    Using expressed sequence tag (EST) analysis, we previously identified certain molecular machinery that mediates antidepressant effects. To date, several partial cDNA fragments, termed antidepressant-related genes (ADRGs), have been isolated as ESTs from rat brain. In the present study, we identified two of the ADRGs to be rat neuroserpin. Using real-time quantitative PCR, we demonstrated increased neuroserpin mRNA expression in rat frontal cortex after chronic treatment with several classes of antidepressants, including imipramine, fluoxetine, sertraline, and venlafaxine. Electroconvulsive treatment (ECT), another therapeutic treatment for depression, also increased neuroserpin expression in rat frontal cortex. Neuroserpin is a serine protease inhibitor that is implicated in the regulation of synaptic plasticity, neuronal migration, and axogenesis in the central nervous system. In conclusion, our results support the hypothesis that neuroserpin-mediated plastic changes in frontal cortex may underlie the therapeutic action of antidepressants and ECT.

    Selective Serotonin Reuptake Inhibitors (SSRIs) are commonly used drugs for the treatment of psychiatric diseases including major depressive disorder (MDD). For unknown reasons a substantial number of patients do not show any improvement during or after SSRI treatment. We treated DBA/2J mice for 28 days with paroxetine and assessed their behavioral response with the forced swim test (FST). Paroxetine-treated long-time floating (PLF) and paroxetine-treated short-time floating (PSF) groups were stratified as proxies for drug non-responder and responder mice, respectively. Proteomics and metabolomics profiles of PLF and PSF groups were acquired for the hippocampus and plasma to identify molecular pathways and biosignatures that stratify paroxetine-treated mouse sub-groups. The critical role of purine and pyrimidine metabolisms for chronic paroxetine treatment response in the mouse was further corroborated by pathway protein expression differences in both mice and patients that underwent chronic antidepressant treatment. The integrated -omics data indicate purine and pyrimidine metabolism pathway activity differences between PLF and PSF mice. Furthermore, the pathway protein levels in peripheral specimens strongly correlated with the antidepressant treatment response in patients. Our results suggest that chronic SSRI treatment differentially affects purine and pyrimidine metabolisms, which may explain the heterogeneous antidepressant treatment response and represents a potential biosignature.

    Oxidative stress has been claimed a place in pathophysiology of depression; however, the details of the neurobiology of this condition remains incompletely understood. Recently, treatments employing antioxidants have been thoroughly researched. Ferulic acid (FA) is a phenolic compound with antioxidant and antidepressant-like effects. Herein, we investigated the involvement of the antioxidant activity of chronic oral FA treatment in its antidepressant-like effect using the tail suspension test (TST) and the forced swimming test (FST) in mice. The modulation of antioxidant system in blood, hippocampus and cerebral cortex was assessed after stress induction through TST and FST. Our results show that FA at the dose of 1 mg/kg has antidepressant-like effect without affecting locomotor activity. The stress induced by despair tests was able to decrease significantly the activities of superoxide dismutase (SOD) in the blood, catalase (CAT) in the blood and cerebral cortex and glutathione peroxidase (GSH-Px) in the cerebral cortex. Thiobarbituric acid-reactive substances (TBA-RS) levels were increased significantly in the cerebral cortex. Furthermore, the results show that FA was capable to increase SOD, CAT and GSH-Px activities and decrease TBA-RS levels in the blood, hippocampus and cerebral cortex. These findings demonstrated that FA treatment in low doses is capable to exert antidepressant-like effect with the involvement of the antioxidant defense system modulation.

    Hyperlipidemia is associated with increased risk of coronary artery disease and stroke, both of which, in turn, are risk factors of old-age depression. Statins are extensively used for decreasing cholesterol levels. Clinical investigations revealed that long-term use of statins appeared to be associated with a lower risk of anxiety and depression. However, the antidepressant property of statins has not been well examined. This study aimed at examining the antidepressant-like effects of statins in rats exposed to chronic mild stress (CMS). We found that animals exposed to CMS for 4 weeks developed depressive-like state, shown by forced swim test and sucrose preference test. However, these CMS-induced behavioral changes were reversed by simvastatin (5 or 10mg/kg/day) for 14 days, comparable to imipramine (10mg/kg/day) treatment. Locomotor activity and anxiety-like behaviors were not altered by CMS or these treatments. These results demonstrated antidepressant-like effects of statin in CMS model of rats and suggested the potential that statins could be used to facilitate antidepressant treatment in clinical setting.

    To gain insight into the possible immune targets of antidepressant, we evaluated the expression of several inflammatory mediators in the hypothalamus of rats chronically (28 days) treated with the serotonin selective reuptake inhibitor fluoxetine (5mg/kg, i.p.) or the tricyclic compound imipramine (15 mg/kg, i.p.). We focused our attention on the hypothalamus as it plays a key role in determining many of the somatic symptoms experienced by depressed patients. This brain region, critical also for expression of motivated behaviours, participates in the control of the hypothalamic-pituitary-adrenal axis activity and in stress response as well as coordinates physiological functions such as sleep and food intake that have been found altered in a high percentage of depressed patients. Notably, hypothalamus is a key structure for brain cytokine expression and function as it integrates signals from the neuro, immune, endocrine systems. By means of quantitative Real Time PCR experiments we demonstrated that a chronic treatment with either fluoxetine or imipramine resulted in a reduction of IL-6 and IFN-γ mRNAs and increased IL-4 mRNA expression in the rat hypothalamus. Moreover, we demonstrated that hypothalamic expression of members of IL-18 system was differentially affected by chronic antidepressant treatments. Chronically administered fluoxetine decreased IL-8 and CX3CL1 hypothalamic expression, while a chronic treatment with imipramine decreased p11 mRNA. Our data suggest that a shift in the balance of the inflammation toward an anti-inflammatory state in the hypothalamus may represent a common mechanism of action of both the chronic treatments with fluoxetine and imipramine. © 2013 Published by Elsevier B.V.

    Many studies note that changes in oxidative balance are involved in the pathogenesis of major depressive disorder (MDD) and in the success of some antidepressants. Quetiapine exerts a therapeutic response and induces changes in physiological mechanisms that appear to underlie MDD. The objective of this study was to evaluate the antidepressant and antioxidant effects of quetiapine (20 mg /kg) in adult animals. Sixty minutes after an acute treatment or the last administration of chronic treatment (14 days) with quetiapine, animals were subjected to the forced swimming test (FST) to evaluate mobility parameters. Then, the hippocampus, prefrontal cortex (CPF), amygdala and nucleus accumbens (NAc) were removed for the assessment of oxidative stress parameters. Both acute and chronic treatments exerted antidepressant-like effects. Myeloperoxidase (MPO) activity was reduced in the amygdala after acute treatment and in the hippocampus, PFC and amygdala after chronic treatment. In addition, after chronic treatment, the levels of thiobarbituric reactive species (TBARS) were reduced in the amygdala and NAc, and the protein carbonyl content was reduced in the CPF. Superoxide dismutase (SOD) activity increased in the NAc after acute and chronic treatments. Catalase (CAT) activity increased in the PFC after acute treatment and in the NAc after acute and chronic treatments. The concentration of nitrite/nitrate was lower in the CPF after chronic treatment. These results corroborate the antidepressant effect of quetiapine and indicate that quetiapine exhibits an antioxidant profile, a physiological mechanism that appears be involved in the therapeutic function of quetiapine in individuals resistant to classical antidepressant treatments.

  7. Nonnarcotic analgesics and tricyclic antidepressants for the treatment of chronic nonmalignant pain.

    Chronic nonmalignant pain is often characterized by multiple treatment failures, a pattern of maladaptive behavior, and depression. Often there is a history of inappropriate and excessive use of medications for pain. Prior and ongoing use of narcotics and sedatives acts to compound and aggravate the chronic pain syndrome. A first step in treatment is controlled withdrawal of these agents. Nonnarcotic analgesics, NSAIDs, and tricyclic antidepressants are commonly employed in patients with chronic pain. Effective use of these agents requires understanding of their pharmacokinetic and pharmacodynamic properties. Use of a fixed-time schedule is necessary to achieve an effective, sustained therapeutic response. Careful patient education and monitoring for side effects and toxicity are necessary, particularly in the elderly and patients with coexisting medical disorders. Incidence of side effects and toxicity may be reduced by choice of drug and modification of dosing regimen. Nonnarcotic analgesics, TCAs, and NSAIDs are seldom effective by themselves in resolving the pain and distress of patients with chronic nonmalignant pain. This is particularly true when maladaptive behavior coexists. A comprehensive multimodal pain management program encompassing additional pain-relieving strategies and behavior-modifying techniques should be considered and utilized in conjunction with medication.

    Chronic unpredictable stress (CUS) is a widely used animal model of depression. The present study was undertaken to investigate behavioral, physiological and molecular effects of CUS and/or chronic antidepressant treatment (venlafaxine or imipramine) in the same set of animals. Anhedonia, a core symptom of depression, was assessed by measuring consumption of a palatable solution. Exposure to CUS reduced intake of a palatable solution and this effect was prevented by chronic antidepressant treatment. Moreover, chronic antidepressant treatment decreased depressive-like behavior in a modified forced swim test in stressed rats. Present evidence suggests a role for brain-derived neurotrophic factor (BDNF) in depression. BDNF mRNA levels in the ventral and dorsal hippocampus were assessed by in situ hybridization. Exposure to CUS was not correlated with a decrease but rather with an increase in BDNF mRNA expression in both the dentate gyrus of the dorsal hippocampus and the CA3 region of the ventral hippocampus indicating that there is no simple link between depression-like behaviors per se and brain BDNF levels in rats. However, a significant increase in BDNF mRNA levels in the dentate gyrus of the dorsal hippocampus correlated with chronic antidepressant treatment emphasizing a role for BDNF in the mechanisms underlying antidepressant activity.

    Clinical practice guidelines consider the use of antidepressants as one of the standard treatments for anxiety disorders, due to the significant improvements obtained in quality of life and functional disability. In addition, in patients who have not achieved a favorable response after 3 months of psychotherapy, antidepressants are recommended as part of a combined treatment approach. This combination with psychotropic drugs and psychotherapy appears to be indicated from baseline in patients with moderate, severe or recurrent depression. In the last decade, antidepressant prescription rates in general practice have increased between 4 and 10 times. Depression presents high rates of relapse and recurrence. Treatment is often interrupted prematurely, leading to increases in both relapse rates and health care costs. Few studies have analysed the chronic use of antidepressant drugs and long-term adherence. To evaluate compliance with antidepressant treatment between 2003 and 2011 and to explore the associated factors. Retrospective cohort study of antidepressant dispensing. Health Region of Lleida between 2003 and 2011. Patients with chronic prescription of antidepressants (ATC code NO6A) during 2003 were followed up until December 2011. The sample comprised 3684 subjects. The compliance rate was calculated on the basis of the number of units withdrawn from the pharmacy and the theoretical number of units required according to the scheduled duration of treatment: compliance was defined in cases with scores greater than or equal to 80%. 12.5% of patients received chronic antidepressant treatment for at least 4 years. Mean age was 54 years, and 73.2% of patients were female. Almost a third (32.4%) presented anxiety disorders and 26.5% mood disorders. The overall compliance rate was 22% (28% in patients with depression, and 21% in patients with anxiety). According to gender, compliance rates were 21.4% for males and 22.4% for females. Compliance was more likely in

    Full Text Available The involvement of serotonin (5-HT in chronic pain mechanisms is established. 5-HT inhibits central painful stimuli, but recent data suggests that 5-HT could also enhance pain stimulus from the periphery, where mast cells play an important role. We aimed in our study to clarify the influence of selected tricyclic antidepressants (TCAs on mast cell function: secretion, uptake, and reuptake of 5-HT, that could interfere with 5-HT levels and in this way contribute to the generation of pain. As an experimental model, we used isolated rat peritoneal mast cells and incubated them with selected TCAs (clomipramine, amitriptyline, doxepin, and imipramine under different experimental conditions. 5-HT release, uptake, and reuptake were determined spectrofluorometrically. We showed that TCAs were able to inhibit 5-HT secretion from mast cells, as well as uptake of exogenous 5-HT and reuptake of secreted 5-HT back into mast cells. The effects of TCAs were concentration dependent; higher concentrations of TCAs inhibited the secretion of 5-HT induced by compound 48/80, whereas lower concentrations of TCAs inhibited 5-HT uptake. The most effective TCA was halogenated clomipramine. As TCAs are well introduced in chronic pain treatment, the insight into mechanisms of action is important for an understanding of their effect in various pain conditions.

    In the present study, the effects of both single (6 mmol L-serine/10 ml/kg orally administrated) and chronic (2% L-serine solution freely given for 28 days) treatments on depression-like behavior were evaluated in Wistar rats, representing the control, and Wistar Kyoto rats, representing an animal model of depression. Both single and chronic L-serine treatments decreased the duration of immobility, which is an index of a depressive-like state, in the forced swimming test in both strains. However, the decreases in the duration of immobility appear to be regulated differently by the different mechanisms involved in single and chronic L-serine treatments. In the prefrontal cortex and hippocampus, single L-serine treatment increased the concentrations of L-serine, but not D-serine, while chronic L-serine treatment increased those of D-serine, but not L-serine. These data suggest that the antidepressant-like effects of single and chronic L-serine treatments may have been induced by the increased L-serine and D-serine concentrations, respectively, in the brain. In addition, chronic L-serine treatment increased cystathionine concentrations in the hippocampus and prefrontal cortex in Wistar rats, but not in Wistar Kyoto rats, suggesting that Wistar Kyoto rats have an abnormality in the serine-cystathionine metabolic pathway. In conclusion, single and chronic L-serine treatments may induce antidepressant-like effects via the different mechanisms related to serine metabolism in the brain.

    The influence of chronic electroconvulsive seizure (ECS) or antidepressant drug treatments on expression of brain-derived neurotrophic factor (BDNF) and its receptor, trkB, was examined by in situ hybridization and Northern blot. In frontal cortex, acute ECS increased BDNF mRNA approximately twofold, an effect significantly augmented by a prior course of chronic ECS treatment (10 d). In the hippocampus, the influence of chronic ECS varied between the major subfields. In the dentate gyrus granule cell layer, chronic ECS decreased the acute induction of BDNF and trkB mRNA by approximately 50%, but prolonged their expression: levels remained elevated two- to threefold 18 hr later after the last chronic ECS treatment, but returned to control 18 hr after acute ECS. In CA3 and CA1 pyramidal cell layers, chronic ECS significantly elevated the acute induction of BDNF, and tended to prolong the expression of BDNF and trkB mRNA. A similar effect was observed in layer 2 of the piriform cortex, where chronic ECS significantly increased the acute induction and prolonged the expression of BDNF and trkB mRNA. Chronic (21 d), but not acute (1 d), administration of several different antidepressant drugs, including tranylcypromine, sertraline, desipramine, or mianserin, significantly increased BDNF mRNA and all but mianserin increased trkB mRNA in hippocampus. In contrast, chronic administration of nonantidepressant psychotropic drugs, including morphine, cocaine, or haloperidol, did not increase levels of BDNF mRNA. Furthermore, chronic administration of ECS or antidepressant drugs completely blocked the down-regulation of BDNF mRNA in the hippocampus in response to restraint stress. The enhanced induction and prolonged expression of BDNF in response to chronic ECS and antidepressant drug treatments could promote neuronal survival, and protect neurons from the damaging effects of stress.

    Depression's neurobiology begins to be better understood. The last decade data considers neuroplasticity and stress as implicated factors on the pathophisiology of depression. Because antidepressants have a lag-time on their action it is possible that inhibition of neurotransmitters recaptation is not sufficient to explain long term changes. For that purpose, neurogenesis increase, nervous fibers sprouting, new synapses and stabilization of the old ones can be responsible for those changes. AMPc-MAPcinases-CREB-BDNF cellular cascade can play a significant role in the mechanisms of dendritic restructuration, hippocampal neurogenesis increase and nervous cells survival. The aim of this article is to discuss if apoptosis could play a key role as an ethiopathogenic factor on the patogenesis of depression. It was done a medline search for references with apoptosis, stress, neuroplasticity, depression and antidepressants key-words. It were found 101 original or review references about these subjects. Stress plays a key role in the etiopathogeny of depression. Its deletery effects on apoptosis and neuroplasticity can be changed by antidepressants. Neurogenesis' increase is necessary for their action. This increase is reached with chronic antidepressant treatment and not with other psychotropic drugs which means some pharmacological specificity of antidepressants. AMPc, CREB, BDNF and Bcl-2 can be considered as target genes in antidepressant synthesis. At the level of this neurotrophic factors apoptosis might be included in the neuroplastic model of depression and play a prominent role in etiopathogeny of depression. To confirm that, we need more research on the field to know which are the mechanisms that trigger apoptosis and its biological significance. In relation to the last one, we can say that is possible to be physiological apoptosis in deteriorated neurons death which cannot make strong connections and pathological apoptosis because of stress via, namely, HPA axis.

    Serotonin reuptake-inhibiting (SRI) antidepressants are the only FDA-approved pharmacotherapies for the treatment of posttraumatic stress disorder (PTSD). To determine efficacy of the second-generation antipsychotic risperidone as an adjunct to ongoing pharmacologic and psychosocial treatments for veterans with chronic military-related PTSD. A 6-month, randomized, double-blind, placebo-controlled multicenter trial conducted between February 2007 and February 2010 at 23 Veterans Administration outpatient medical centers. Of the 367 patients screened, 296 were diagnosed with military-related PTSD and had ongoing symptoms despite at least 2 adequate SRI treatments, and 247 contributed to analysis of the primary outcome measure. Risperidone (up to 4 mg once daily) or placebo. The Clinician-Administered PTSD Scale (CAPS) (range, 0-136). Other measures included the Montgomery-Asberg Depression Rating Scale (MADRS), Hamilton Anxiety Scale (HAMA), Clinical Global Impression scale (CGI), and Veterans RAND 36-Item Health Survey (SF-36V). Change in CAPS scores from baseline to 24 weeks in the risperidone group was -16.3 (95% CI, -19.7 to -12.9) and in the placebo group, -12.5 (95% CI, -15.7 to -9.4); the mean difference was 3.74 (95% CI, -0.86 to 8.35; t = 1.6; P = .11). Mixed model analysis of all time points also showed no significant difference in CAPS score (risperidone: mean, 64.43; 95% CI, 61.98 to 66.89, vs placebo: mean, 67.16; 95% CI, 64.71 to 69.62; mean difference, 2.73; 95% CI, -0.74 to 6.20; P = .12).

    It is recognized that monoamine reuptake inhibitors (MARIs) exert beneficial effects in the treatment of major depression and general anxiety disorder. The aim of this study was to identify proteins regulated by this class of antidepressant using a proteome differential profiling approach. Either venlafaxine or fluoxetine was administered systemically to adult rats for 2 weeks, and protein patterns from rat hippocampal cytosolic extracts were compared by two-dimensional gel electrophoresis. Silver-stained protein spots displaying differential expression were identified by mass spectrometry. Thirty-three protein spots were modulated by both drug treatments compared to controls. The classification of several proteins that were sorted by function suggested convergent pathway activities for both MARIs at the post-receptor level. These included proteins associated with neurogenesis (insulin like growth factor 1 (IGF-1), glia maturation factor [GMF]-beta), outgrowth/maintenance of neuronal processes (hippocampal cholinergic neurostimulating peptide [HCNP], PCTAIRE-3), and with neural regeneration/axonal guidance collapsin response mediator protein (CRMP-2) systems. Other modulated proteins indicated an increase in neuronal vesicular cell trafficking and synaptic plasticity (Ras-related protein 4a (Rab4a), Ras-related protein 1b (Rab1b), heat shock protein 10 [HSP10]), as well as neurosteroidogenic (hydroxysteroid sulfotransferase A) and possible anti-apoptotic (dimethylargininase-1 L-N,N-dimethylarginine dimethylaminohydrolase-1 [DDAH-1], pyruvate dehydrogenase-E1 [PDH-E1], antioxidant protein-2 [AOP-2]) pathway-mediated regulatory events. Parallel studies to investigate further the effects of venlafaxine and fluoxetine on adult hippocampal neurogenesis in vivo by quantitative bromodeoxyuridine immunolabeling revealed a significant drug-induced increase in the proliferation rate and long-term survivability of progenitor stem cells located in the subgranular zone.

    Selective serotonin reuptake inhibitor use is associated with increased risk of suicidal ideation in adolescent humans, yet the neuropharmacological basis of this phenomenon is unknown. Consequently, we examined the behavioural and neurochemical effects of chronic paroxetine (PRX) treatment in adult and adolescent rats. Rats received PRX in their drinking water (target dose 10 mg/kg) for 22 d, during which time they were assessed for depression- and anxiety-like behaviours. Subsequent ex-vivo analyses examined serum PRX concentrations, striatal neurotransmitter content, and regional serotonin and dopamine transporter (SERT, DAT) binding density. After 11-12 d treatment, PRX-treated adolescent rats showed a significant inhibition of social interaction while adults were unaffected. After 19-20 d treatment, adolescents failed to show an antidepressant-like effect of PRX treatment on the forced swim test (FST), while PRX-treated adults showed a typical decrease in immobility and increase in swimming. Two PRX-treated adolescents died unexpectedly after the FST suggesting a compromised response to physical stress. Despite their greater apparent adverse reaction to the drug, adolescents had significantly lower plasma PRX than adults at day 22 of treatment. Chronic PRX treatment had similar effects in adults and adolescents on striatal 5-HT (unchanged relative to controls) and 5-HIAA levels (decreased), while markers of dopaminergic function (DOPAC, HVA, DA turnover) were increased in adults only. SERT density was up-regulated in the amygdala in PRX-treated adolescents only while DAT density in the nucleus accumbens was down-regulated only in PRX-treated adults. These data suggest that the immature rat brain responds differently to PRX and that this might be of use in modelling the atypical response of human adolescents to antidepressants. The age-specific PRX-induced changes in dopaminergic markers and SERT and DAT binding provide clues as to the neural mechanisms

    Antidepressant medication is generally considered the primary treatment for major depressive disorders (MDD), but antidepressant treatment has recently approached a crisis with shrinking specific effects and growing placebo responses in current trials. The aim of the paper is to review the placebo...... problem within antidepressant treatment for MDD, and to draw lines to similar problems within the field of psychotherapy. Although clinicians might profit from the large placebo response in their treatment of MDD, the small differences between active treatment and placebo groups found in controlled...

  1. Mechanisms Underlying the Antidepressant Response and Treatment Resistance

    Full Text Available Depression is a complex and heterogeneous disorder affecting millions of Americans. There are several different medications and other treatments that are available and effective for many patients with depression. However, a substantial percentage of patients fail to achieve remission with these currently available interventions, and relapse rates are high. Therefore, it is necessary to determine both the mechanisms underlying the antidepressant response and the differences between responders and non-responders to treatment. Delineation of these mechanisms largely relies on experiments that utilize animal models. Therefore, this review provides an overview of the various mouse models that are currently used to assess the antidepressant response, such as chronic mild stress, social defeat, and chronic corticosterone. We discuss how these mouse models can be used to advance our understanding of the differences between responders and non-responders to antidepressant treatment. We also provide an overview of experimental treatment modalities that are used for treatment-resistant depression, such as deep brain stimulation and ketamine administration. We will then review the various genetic polymorphisms and transgenic mice that display resistance to antidepressant treatment. Finally, we synthesize the published data to describe a potential neural circuit underlying the antidepressant response and treatment resistance.

    The experiments has been designed to study unpredictable chronic mild stress effect on anti-depressive activities of amitriptyline (10 mg/kg) and fluoxetine (20 mg/kg) in forced swim test in male outbred mice. It is shown that acute treatment with fluoxetine does not produce any antidepressant effects in mice following stress of 14 days while the sub-chronic injections of fluoxetine result in more deep depressive-like behavior. In 28 daily stressed mice, antidepressant effect of fluoxetine is observed independently of the injection rates. Amitriptyline demonstrates the antidepressant activity regardless of the duration of stress or administration scheduling, but at the same time the severity of anti-immobilization effect of amitriptyline in stressed mice is weaker in compare to non-stressed trails. Thus, the injection rates and duration of unpredictable mild chronic stress are the parameters that determine the efficiency of antidepressants in the mouse forced swimming test.

    The current knowledge of the pharmacological actions of the tricyclic antidepressants (TCAs) has slowly evolved through their over 40-year history. Chronic pain represents one of the most important public health problems, and antidepressants are an essential part of the therapeutic strategy in addition to classical analgesics. This article reviews the available evidence on the efficacy and safety of antidepressants in chronic pain conditions; namely, headaches, low back pain, fibromyalgia, cancer pain and especially neuropathic pain. TCAs are traditionally the main type of depression medication used to treat chronic pain. Recently, new antidepressants were introduced into clinical use, with a significant reduction in side effects and equivalent efficacy on mood disorders. These new drugs that are effective for chronic pain belong to the tetracyclic antidepressants (TeCAs) group (amoxapine, maprotiline), the serotonin and noradrenaline reuptake inhibitors (SNRIs) group (duloxetine, venlafaxine, milnacipran) and the atypical antidepressants group (bupropion, trazodone, mirtazapine, nefazodone). In this review, we present the available publications on TCAs (amitriptyline, doxepin, imipramine, desipramine, nortriptyline), TeCAs (amoxapine, maprotiline), selective serotonin reuptake inhibitors (SSRIs) (citalopram, fluoxetine, paroxetine), SNRIs (duloxetine, venlafaxine, milnacipran) and atypical antidepressants (bupropion) for the treatment of neuropathic pain. We also review analgesics acting as both opioid receptor agonists and also acting as aminergic reuptake inhibitors. Existing data are insufficient to conclude which of these new classes of antidepressants has the best clinical profile and will be the most effective in the treatment of neuropathic pain; in addition, a lower incidence of side effects should be considered. Increased experimental and translational research is a key for further improvement of the treatment of chronic pain with antidepressants. However

    Full Text Available Poisoning with tricyclic antidepressants is one of the main causes of morbidity and mortality compared to all the antidepressants. Main toxic effects are on the cardiovascular system and central nervous system and manifests itself as anticholinergic symptoms. There is no antidote known to be used in the treatment. But sodium bicarbonate treatment is effective in preventing ventricular arrhythmias and hypotension, and resolving metabolic acidosis. There are some treatments that has been used for relief of symptoms and some of them still are in research stage. The drugs that are used can be customized according to the patients symptoms.

    Chronic antidepressant treatment has been shown to increase adenylyl cyclase activity, in part, due to translocation of Galpha(s) from lipid rafts to a nonraft fraction of the plasma membrane where they engage in a more facile stimulation of adenylyl cyclase. This effect holds for multiple classes of antidepressants, and for serotonin uptake inhibitors, it occurs in the absence of the serotonin transporter. In the present study, we examined the change in the amount of Galpha(s) in lipid raft and whole cell lysate after exposing C6 cells to escitalopram. The results showed that chronic (but not acute) escitalopram decreased the content of Galpha(s) in lipid rafts, whereas there was no change in overall Galpha(s) content. These effects were drug dose- and exposure time-dependent. Although R-citalopram has been reported to antagonize some effects of escitalopram, this compound was without effect on Galpha(s) localization in lipid rafts, and R-citalopram did not inhibit these actions of escitalopram. Escitalopram treatment increased cAMP accumulation, and this seemed due to increased coupling between Galpha(s) and adenylyl cyclase. Thus, escitalopram is potent, rapid and efficacious in translocating Galpha(s) from lipid rafts, and this effect seems to occur independently of 5-hydroxytryptamine transporters. Our results suggest that, although antidepressants display distinct affinities for well identified targets (e.g., monoamine transporters), several presynaptic and postsynaptic molecules are probably modified during chronic antidepressant treatment, and these additional targets may be required for clinical efficacy of these drugs.

    Depressive disorders place a large burden on patients and on society. Although efficacious treatment options for unipolar depressive disorders exist, substantial gaps in care remain. In part, the challenge lies in the matching of individual patients with appropriate care. This is complicated by the steady increases in the variety of antidepressants available in the market. The goal of this study is to highlight the decision processes in the selection of antidepressants by clinicians, given that most treatments have similar clinical effectiveness profiles. We conducted a systematic literature review of studies that referred to the decisions surrounding treatment with antidepressants for the treatment of non-psychotic unipolar depression. Our analysis of the literature reveals that the choice of treatment is based on a variety of factors, of which clinical evidence is only one. These factors can be categorized into clinical factors such as illness and treatment characteristics, individual factors such as patient and physician characteristics, and contextual factors such as setting characteristics, decision supports and pharmacoeconomic aspects. Illness characteristics are defined by the type and severity of depression. Treatment characteristics include drug properties, efficacy, effectiveness and favorable as well as unintended adverse effects of the drug. Examples for patient characteristics are co-morbidities and individual preferences, and physician characteristics include knowledge, experience, values and beliefs, and the relationship with the patient. Treatment guidelines, algorithms, and most recently, computational supports and biological markers serve as decision supports.

    There is a close relationship between chronic stress, glucocorticoids and depression. Psychiatric and cognitive symptoms resembling major depression have been observed in patients experiencing elevated glucocorticoid levels, and a high percentage of people suffering from depression have undergone a stressful event/events prior to the onset of this mental disorder. In our study, we investigated whether acute and chronic treatment of dexamethasone induces depression-like behavior in mice and if dexamethasone therapy influences the activity of antidepressant drugs with diverse modes of action. The antidepressant-like effect was assessed by the forced swim test in adult mice. The depressogenic-like activity of dexamethasone turned out to be dose-dependent: only the highest tested dose of the glucocorticoid (i.e., 64μg/kg) given as a single injection increased immobility time, whereas 16μg/kg/day of dexamethasone (but not 4μg/kg/day) administered repeatedly induced a significant alteration in animal behavior. These depressogenic doses of dexamethasone (i.e., 64μg/kg and 16μg/kg/day for an acute and repeated administration, respectively) diminished the antidepressant potential of the therapeutic doses of imipramine (10mg/kg), amitriptyline (10mg/kg), tianeptine (25mg/kg), mianserin (10mg/kg), citalopram (15mg/kg) and moclobemide (25mg/kg). Two main findings of our study should be particularly underlined: (1) both single and repeated administration of dexamethasone evoked a depression-like behavior of mice, (2) both single and repeated administration of dexamethasone were able to modify the activity of the antidepressant agents from various pharmacological groups, which may lead to a considerable reduction in the efficacy of pharmacotherapy prescribed for patients with mood disorders.

    Stress activates the hypothalamo-pituitary-adrenal (HPA) axis, regulates the expression of brain-derived neurotrophic factor (BDNF) in the brain, and mediates mood. Antidepressants alleviate stress and up-regulate BDNF gene expression. In this study, we investigated the effect of chronic unpredictable mild stress (CUMS) and the different kinds of antidepressant treatments on the HPA axis and the BDNF expression in the rat brain. Adult Wistar male rats were exposed to a six-week CUMS procedure and received different antidepressant treatments including venlafaxine, mirtazapine, and fluoxetine. Immunohistochemistry and real-time PCR were used to measure BDNF expression levels in the rat brain, and ELISAs were used to investigate the plasma corticosterone (CORT) and adrenocorticotropic hormone (ACTH) levels. CUMS significantly decreased the BDNF protein level in the DG, CA1, and CA3 of the hippocampus and increased plasma CORT level. Chronic antidepressant treatments all significantly increased BDNF protein levels in the hippocampus and the pre-frontal cortex. In addition, venlafaxine and mirtazapine inhibited the increase of plasma CORT level. These results suggested that an increase in the BDNF level in the brain could be a pivotal mechanism of various antidepressants to exert their therapeutic effects.

    Major depression and bipolar disorder are associated with decreased bone mineral density (BMD). Antidepressants such as imipramine (IMIP) and specific serotonin reuptake inhibitors (SSRIs) have been implicated in reduced BMD and/or fracture in older depressed patients. Moreover, anticonvulsants such as valproate (VAL) and carbamazepine (CBZ) are also known to increase fracture rates. Although BMD is a predictor of susceptibility to fracture, bone strength is a more sensitive predictor. We measured mechanical and geometrical properties of bone in 68 male Sprague Dawley rats on IMIP, fluoxetine (FLX), VAL, CBZ, CBZ vehicle and saline (SAL), given intraperitoneally daily for 8 weeks. Distinct regions were tested to failure by four-point bending, whereas load displacement was used to determine stiffness. The left femurs were scanned in a MicroCT system to calculate mid-diaphyseal moments of inertia. None of these parameters were affected by antidepressants. However, VAL resulted in a significant decrease in stiffness and a reduction in yield, and CBZ induced a decrease in stiffness. Only CBZ induced alterations in mechanical properties that were accompanied by significant geometrical changes. These data reveal that chronic antidepressant treatment does not reduce bone strength, in contrast to chronic anticonvulsant treatment. Thus, decreased BMD and increased fracture rates in older patients on antidepressants are more likely to represent factors intrinsic to depression that weaken bone rather than antidepressants per se. Patients with affective illness on anticonvulsants may be at particularly high risk for fracture, especially as they grow older, as bone strength falls progressively with age.

    With the antidepressant efficacy of Transcranial Magnetic Stimulation well-established by several meta-analyses, there is growing interest in its mechanism of action. TMS has been shown to engage, and in some cases, normalize functional connectivity and neurotransmitter levels within networks dysfunctional in the depressed state. In this review, I will suggest candidate biomarkers, based on neuroimaging, that may be predictive of response to TMS. I will then review the effects of TMS on networks and neurotransmitter systems involved in depression. Throughout, I will also discuss how our current understanding of response predication and network engagement may be used to personalize treatment and optimize its efficacy.

    Obsessive-compulsive disorder (OCD) is a chronic neuropsychiatric disorder with high genetic influence. Antidepressants such as serotonin reuptake inhibitors, are widely accepted as the first-line medications for OCD; however, approximately 50% of OCD patients show poor response. Personalized medicine utilizing genetic testing has recently received much attention because the variability of antidepressant response and tolerability are partly due to an individual's genetic variations. This has led to researchers investigating the role of specific genetic factors on antidepressant response and utility of testing in the clinical realm. Genetic test panels are showing promise for guiding antidepressant treatment to improve outcomes in depression. This article will review the most recent findings in the pharmacogenetics of OCD and its related disorders. Promising results have been reported for several serotonergic and glutamatergic system genes and the cytochrome CYP450 liver enzyme genes, which appear to play an important role in OCD and antidepressant response.

    In short-term efficacy studies, coprescription of a benzodiazepine improves first-month adherence and response to antidepressant treatment. We used Veterans Health Administration data to examine the impact of coprescribed benzodiazepines on initial antidepressant adherence in routine clinical practice and the risks of long-term benzodiazepine use, abuse, and dependence. Our study population was 43,915 Veterans Health Administration patients diagnosed with depression and started on an antidepressant between October 2006 and September 2007. Using logistic regression, adjusting for demographic and clinical covariates, we predicted the likelihood that patients received antidepressant treatment for an adequate duration (90 days), with our primary independent variable of interest being receipt of a benzodiazepine on the same day as the start of the antidepressant. We also assessed the frequency and characteristics of patients whose benzodiazepine use persisted for 1 year or who were diagnosed with anxiolytic abuse or dependence after receiving combined treatment. The adjusted probability of receiving antidepressant treatment of adequate duration was 42.4% for patients who received a benzodiazepine with their initial antidepressant compared with 39.3% for patients initially treated with an antidepressant alone (P benzodiazepines for at least 1 year, and 0.7% were diagnosed with anxiolytic abuse or dependence. Anxiolytic abuse or dependence, but not long-term benzodiazepine use, was associated with other substance use disorders. These findings should be considered by clinicians when assessing the individual risks and benefits of combining a benzodiazepine with antidepressant treatment.

    Depression is common in patients receiving chronic hemodialysis but seems to be ineffectively treated. We investigated the acceptance of antidepressant treatment by patients on chronic hemodialysis and their renal providers. As part of a clinical trial of symptom management in patients on chronic hemodialysis conducted from 2009 to 2011, we assessed depression monthly using the Patient Health Questionnaire 9. For depressed patients (Patient Health Questionnaire 9 score ≥10), trained nurses generated treatment recommendations and helped implement therapy if patients and providers accepted the recommendations. We assessed patients' acceptance of recommendations, reasons for refusal, and provider willingness to implement antidepressant therapy. We analyzed data at the level of the monthly assessment. Of 101 patients followed for ≤12 months, 39 met criteria for depression (Patient Health Questionnaire 9 score ≥10 on one or more assessments). These 39 patients had depression on 147 of 373 (39%) monthly assessments. At 103 of these 147 (70%) assessments, patients were receiving antidepressant therapy, and at 51 of 70 (70%) assessments, patients did not accept nurses' recommendations to intensify treatment. At 44 assessments, patients with depression were not receiving antidepressant therapy, and in 40 (91%) instances, they did not accept recommendations to start treatment. The primary reason that patients refused the recommendations was attribution of their depression to an acute event, chronic illness, or dialysis (57%). In 11 of 18 (61%) instances in which patients accepted the recommendation, renal providers were unwilling to provide treatment. Patients on chronic hemodialysis with depression are frequently not interested in modifying or initiating antidepressant treatment, commonly attributing their depression to a recent acute event, chronic illness, or dialysis. Renal providers are often unwilling to modify or initiate antidepressant therapy. Future efforts

    Background Up to now there have been no satisfactory drugs to treat psychiatric disorders, and now bioactive compound from entomagenous fungi (BCEF0083) is a new type of bioactive compound from entomopathogenic fungi. Our previous investigations have shown that BCEF has an inhibition effect on monoamine oxidase. So, BCEF may be a latent antidepressant. This study aimed at observing the antidepressant effects and its mechanism of BCEF in the chronic unpredictable stress models in mice. Methods The antidepressant effects of BCEF were examined on the chronic unpredictable stress models in mice. Sixty mice were randomly divided to six groups. Animals were housed and isolated except saline group. Mice were exposed to different stressors per day randomly from day 1 to day 21. Body weight were weighed on day 1,day 10 and on day 21 during the 21-day stress procedure. Awarding response was detected by using method of calculating the 24-hour consumption of saccharum water. Step through test was used to evaluate the behavioral response. AVP contents in plasma were also detected by using radioimmunoassays. Results Chronic unpredictable stress resulted in a significant decrease of the body weight and could apparently cause escape behavior disturbance and gradual reduction of sensitivity to reward in animal models. Drug treatment (BCEF 25, 50, 100 mg/kg) could significantly ameliorate the decreased body weight and effectively reverse the escape behavior disturbance. The gradual reduction of sensitivity to reward, the anhedonic state, was also effectively reversed by BCEF. BCEF (50, 100 mg/kg) could also effectively restore the AVP content in the plasma.Conclusions This evidence suggests that BCEF can effectively inhibit the depression behavior and show strong antidepressant effect. BCEF can effectively restore the plasma AVP release and this may be an important mechanism of its antidepressant effect.

    Antidepressants are one of the most common treatment strategies for patients diagnosed with major depressive disorder (MDD). However, antidepressant medications have different mechanisms of action that can theoretically and in practice affect how patients respond. Clinicians should assess their patients' symptoms and response to medication at every visit to determine whether or not the treatment is fully effective. Here, follow the case of Maria, a 42-year-old teacher who is experiencing her first depressive episode.

    Osteoporosis is a chronic skeletal disease marked by microarchitectural deterioration of the bone matrix and depletion of bone mineral density (BMD), with a consequent increased risk for fragility fractures. It has been frequently associated with depression, which is also a chronic and debilitating disorder with high prevalence. Selective serotonin reuptake inhibitors (SSRIs), first-line agents in the pharmacological treatment of mood and anxiety disorders, have also been shown to negatively affect bone metabolism. SSRIs are the most prescribed antidepressants worldwide and a large number of persons at risk of developing osteoporosis, including older patients, will receive these antidepressants. Therefore, a proper musculoskeletal evaluation of individuals who are being targeted for or using SSRIs is a priority. The aim of this article is to review the evidence regarding the effects of depression and serotonergic antidepressants on bone and its implications for clinical care.

    Full Text Available Adenylyl cyclase (AC-cyclic adenosine monophosphate (cAMP-cAMP-dependent protein kinase A (PKA cascade is considered to be associated with the pathogenesis and treatment of depression. The present study was conducted to explore the role of the cAMP cascade in antidepressant action of electroacupuncture (EA treatment for chronic mild stress (CMS-induced depression model rats. The results showed that EA improved significantly behavior symptoms in depression and dysfunction of AC-cAMP-PKA signal transduction pathway induced by CMS, which was as effective as fluoxetine. Moreover, the antidepressant effects of EA rather than Fluoxetine were completely abolished by H89, a specific PKA inhibitor. Consequently, EA has a significant antidepressant treatment in CMS-induced depression model rats, and AC-cAMP-PKA signal transduction pathway is crucial for it.

The reported incidence of sexual dysfunction associated with antidepressant medication varies considerably between studies, making it difficult to estimate the exact incidence or prevalence. The sexual problems reported range from decreased sexual desire, decreased sexual excitement, diminished or delayed orgasm, to erection or delayed ejaculation problems. There are a number of case reports of sexual side effects, such as priapism, painful ejaculation, penile anesthesia, loss of sensation in the vagina and nipples, persistent genital arousal and nonpuerperal lactation in women. The focus of this article is to explore the incidence, pathophysiology, and treatment of antidepressant iatrogenic sexual dysfunction.Keywords: depression, antidepressant, iatrogenic sexual dysfunction, SSRI, SNRI

    Under-diagnosis and under-treatment of depression are major problems in nursing home residents. The purpose of this study was to determine antidepressant use among nursing home residents who were diagnosed with depression using three different methods: (1) the Geriatric Depression Scale, (2) Minimum Data Set, and (3) primary care provider assessments. As one would expect, the odds of being treated with an antidepressant were about eight times higher for those diagnosed as depressed by the primary care provider compared to the Geriatric Depression Scale or the Minimum Data Set. Men were less likely to be diagnosed and treated with antidepressants by their primary care provider than women. Depression detected by nurses through the Minimum Data Set was treated at a lower rate with antidepressants, which generates issues related to interprofessional communication, nursing staff communication, and the need for geropsychiatric role models in nursing homes.

    Full Text Available While studies in the past have focused more on treatment of the manic phase of bipolar disorder (BD, recent findings demonstrate the depressive phase to be at least as debilitating. However, in contrast to unipolar depression, depression in bipolar patients exhibits a varying response to antidepressants, raising questions regarding their efficacy and tolerability. Methods. We conducted a MEDLINE and Cochrane Collaboration Library search for papers published between 2005 and 2011 on the subject of antidepressant treatment of bipolar depression. Sixty-eight articles were included in the present review. Results. While a few studies did advocate the use of antidepressants, most well-controlled studies failed to show a robust effect of antidepressants in bipolar depression, regardless of antidepressant class or bipolar subtype. There was no significant increase in the rate of manic/hypomanic switch, especially with concurrent use of mood stabilizers. Prescribing guidelines published in recent years rely more on atypical antipsychotics, especially quetiapine, as a first-line therapy. Conclusions. Antidepressants probably have no substantial role in acute bipolar depression. However, in light of conflicting results between studies, more well-designed trials are warranted.

    The present study demonstrates that chronic, but not acute, adminstration of several different classes of antidepressants, including serotonin- and norepinephrine-selective reuptake inhibitors, increases the expression of cAMP response element binding protein (CREB) mRNA in rat hippocampus. In contrast, chronic administration of several nonantidepressant psychotropic drugs did not influence expression of CREB mRNA, demonstrating the pharmacological specificity of this effect. In situ hybridization analysis demonstrates that antidepressant administration increases expression of CREB mRNA in CA1 and CA3 pyramidal and dentate gyrus granule cell layers of the hippocampus. In addition, levels of CRE immunoreactivity and of CRE binding activity were increased by chronic antidepressant administration, which indicates that expression and function of CREB protein are increased along with its mRNA. Chronic administration of the phosphodiesterase (PDE) inhibitors rolipram or papaverine also increased expression of CREB mRNA in hippocampus, demonstrating a role for the cAMP cascade. Moreover, coadministration of rolipram with imipramine resulted in a more rapid induction of CREB than with either treatment alone. Increased expression and function of CREB suggest that specific target genes may be regulated by these treatments. We have found that levels of brain-derived neurotrophic factor (BDNF) and trkB mRNA are also increased by administration of antidepressants or PDE inhibitors. These findings indicate that upregulation of CREB is a common action of chronic antidepressant treatments that may lead to regulation of specific target genes, such as BDNF and trkB, and to the long-term effects of these treatments on brain function.

    Previous studies in our laboratory have demonstrated that piperine produced antidepressant-like action in various mouse models of behavioral despair. This study aimed to investigate the role of brain-derived neurotrophic factor (BDNF) signalling in the antidepressant-like effect of piperine in mice exposed to chronic unpredictable mild stress (CUMS). The results showed that CUMS caused depression-like behavior in mice, as indicated by the significant decrease in sucrose consumption and increase in immobility time in the forced swim test. It was also found that BDNF protein expression in the hippocampus and frontal cortex were significantly decreased in CUMS-treated mice. Chronic treatment of piperine at the dose of 10mg/kg significantly ameliorated behavioural deficits of CUMS-treated mice in the sucrose preference test and forced swim test. Piperine treatment also significantly decreased immobility time in the forced swim test in naive mice. In parallel, chronic piperine treatment significantly increased BDNF protein expression in the hippocampus and frontal cortex of both naive and CUMS-treated mice. In addition, inhibition of BDNF signalling by injection of K252a, an inhibitor of the BDNF receptor TrkB, significantly blocked the antidepressant-like effect of piperine in the sucrose preference test and forced swim test of CUMS-treated mice. Taken together, this study suggests that BDNF signalling is an essential mediator for the antidepressant-like effect of piperine.

    The pharmacological treatment of chronic pain differs from acute pain management. In chronic non-cancer pain patients pharmacological treatment is only one element of an interdisciplinary approach. Not pain reduction only but gain in physical and social functioning is mandatory for continuation of therapy. The developpement of a strategy is the most important and difficult step toward an individual and sustained pharmacological pain treatment. Simple practical guidelines can help to find an individual therapeutic straight. Outcome parameters have to be determined. Check-ups for discontinuation of the therapy have to be done periodically. Exact documentation of effect and side effects prevents ungrateful and potential dangerous treatments. The WHO ladder remains the cornerstone of pharmacological pain treatment. Further analgesics as antidepressants and anticonvulsants are important in treatment of neuropathic or mixed pain states. Special considerations have to be done in opioid treatment of non-cancer pain regarding the lack of evidence in long term outcome and possible side effects and risks.

    The neurogenesis hypothesis of major depression has two main facets. One states that the illness results from decreased neurogenesis while the other claims that the very functioning of antidepressants depends on increased neurogenesis. In order to verify the latter, we have used cyclin D2 knockout mice (cD2 KO mice), known to have virtually no adult brain neurogenesis, and we demonstrate that these mice successfully respond to chronic fluoxetine. After unpredictable chronic mild stress, mutant mice showed depression-like behavior in forced swim test, which was eliminated with chronic fluoxetine treatment, despite its lack of impact on adult hippocampal neurogenesis in cD2 KO mice. Our results suggest that new neurons are not indispensable for the action of antidepressants such as fluoxetine. Using forced swim test and tail suspension test, we also did not observe depression-like behavior in control cD2 KO mice, which argues against the link between decreased adult brain neurogenesis and major depression.

    Sexual dysfunction is a common side effect of antidepressants and can have significant impact on the person's quality of life, relationships, mental health, and recovery. The reported incidence of sexual dysfunction associated with antidepressant medication varies considerably between studies, making it difficult to estimate the exact incidence or prevalence. The sexual problems reported range from decreased sexual desire, decreased sexual excitement, diminished or delayed orgasm, to erection or delayed ejaculation problems. There are a number of case reports of sexual side effects, such as priapism, painful ejaculation, penile anesthesia, loss of sensation in the vagina and nipples, persistent genital arousal and nonpuerperal lactation in women. The focus of this article is to explore the incidence, pathophysiology, and treatment of antidepressant iatrogenic sexual dysfunction.

    Major depression and other depressive conditions are common in people with cancer. These conditions are not easily detectable in clinical practice, due to the overlap between medical and psychiatric symptoms, as described by diagnostic manuals such as the Diagnostic and Statistical Manual of Mental Disorders (DSM) and International Classification of Diseases (ICD). Moreover, it is particularly challenging to distinguish between pathological and normal reactions to such a severe illness. Depressive symptoms, even in subthreshold manifestations, have been shown to have a negative impact in terms of quality of life, compliance with anti-cancer treatment, suicide risk and likely even the mortality rate for the cancer itself. Randomised controlled trials (RCTs) on the efficacy and tolerability of antidepressants in this population group are few and often report conflicting results. To assess the effects and acceptability of antidepressants for treating depressive symptoms in adults (18 years or older) with cancer (any site and stage). We searched the following electronic bibliographic databases: the Cochrane Central Register of Controlled Trials (CENTRAL 2014, Issue 3), MEDLINE Ovid (1946 to April week 3, 2014), EMBASE Ovid (1980 to 2014 week 17) and PsycINFO Ovid (1987 to April week 4, 2014). We additionally handsearched the trial databases of the most relevant national, international and pharmaceutical company trial registers and drug-approving agencies for published, unpublished and ongoing controlled trials. We included RCTs allocating adults (18 years or above) with any primary diagnosis of cancer and depression (including major depressive disorder, adjustment disorder, dysthymic disorder or depressive symptoms in the absence of a formal diagnosis) comparing antidepressants versus placebo, or antidepressants versus other antidepressants. Two review authors independently checked eligibility and extracted data using a form specifically designed for the aims of this

    Hypogonadal men are more likely to develop depression, while testosterone supplementation shows antidepressant-like effects in hypogonadal men and facilitates antidepressant efficacy. Depression is associated with hypothalamic-pituitary-adrenal (HPA) axis hyperactivity and testosterone exerts suppressive effects on the HPA axis. The hippocampus also plays a role in the feedback regulation of the HPA axis, and depressed patients show reduced hippocampal neuroplasticity. We assessed the antidepressant-like effects of testosterone with, or without, imipramine on behavioral and neural endophenotypes of depression in a chronic unpredictable stress (CUS) model of depression. A 21-day CUS protocol was used on gonadectomized male Sprague-Dawley rats treated with vehicle, 1mg of testosterone propionate, 10mg/kg of imipramine, or testosterone and imipramine in tandem. Testosterone treatment reduced novelty-induced hypophagia following CUS exposure, but not under non-stress conditions, representing state-dependent effects. Further, testosterone increased the latency to immobility in the forced swim test (FST), reduced basal corticosterone, and reduced adrenal mass in CUS-exposed rats. Testosterone also facilitated the effects of imipramine by reducing the latency to immobility in the FST and increasing sucrose preference. Testosterone treatment had no significant effect on neurogenesis, though the combination of testosterone and imipramine increased PSA-NCAM expression in the ventral dentate gyrus. These findings demonstrate the antidepressant- and anxiolytic-like effects of testosterone within a CUS model of depression, and provide insight into the mechanism of action, which appears to be independent of enhanced hippocampal neurogenesis.

    Full Text Available Major depression is one of the most common psychiatric disorders, severely affecting the quality of life of millions of people worldwide. Despite the availability of several classes of antidepressants, treatment efficacy is still very variable and many patients do not respond to the treatment. Clomipramine (CMI, a classical and widely used antidepressant, shows widespread interindividual variability of efficacy, while the environmental factors contributing to such variability remain unclear. We investigated whether chronic stress modulates the bio-distribution of CMI, and as a result the behavioral response to CMI treatment in a mouse model of chronic social defeat stress. Our results show that stress exposure increased anxiety-like and depressive-like behaviors and altered the stress response. Chronic defeat stress furthermore significantly altered CMI bio-distribution. Interestingly, CMI bio-distribution highly correlated with anxiety-like and depressive-like behaviors only under basal conditions. Taken together, we provide first evidence demonstrating that chronic stress exposure modulates CMI bio-distribution and behavioral responses. This may contribute to CMI’s broad interindividual variability, and is especially relevant in clinical practice.

    The market for pain treatment is a major segment of nervous system pathologies. Despite this dynamism, the management of some pain conditions remains a clinical challenge. Neuropathic pain arises as a direct consequence of a lesion or disease affecting the somatosensory system. It is generally a chronic and disabling condition which is difficult to treat. Antidepressant drugs are recommended as one of the first line treatments, but they display noticeable side effects and are not effective on all patients. Using a murine model of neuropathy, we demonstrated that the stimulation of beta2-adrenergic receptors (beta2-AR) is not only necessary for antidepressant drugs to exert their antiallodynic action but that it is in fact sufficient to alleviate neuropathic allodynia. Chronic, but not acute, treatment with beta-mimetics such as terbutaline, salbutamol, fenoterol, salmeterol, ritodrine, isoprenaline (isoproterenol), metaproterenol (orciprenaline), procaterol, formoterol, clenbuterol or bambuterol, relieves allodynia. Agonists of beta2-ARs, and more generally any molecule stimulating beta2-ARs such as beta-mimetics, are thus proposed as potential new treatments for neuropathic pain. Clinical studies are now in preparation to confirm this potential in patients with neuropathic pain. This article reviews the findings leading to propose beta-mimetics for neuropathic pain treatment and other recent patents on the topic.

    The outcome of treatment with antidepressants varies markedly across people with the same diagnosis. A clinically significant prediction of outcomes could spare the frustration of trial and error approach and improve the outcomes of major depressive disorder through individualized treatment selection. It is likely that a combination of multiple predictors is needed to achieve such prediction. We used elastic net regularized regression to optimize prediction of symptom improvement and remission during treatment with escitalopram or nortriptyline and to identify contributing predictors from a range of demographic and clinical variables in 793 adults with major depressive disorder. A combination of demographic and clinical variables, with strong contributions from symptoms of depressed mood, reduced interest, decreased activity, indecisiveness, pessimism and anxiety significantly predicted treatment outcomes, explaining 5-10% of variance in symptom improvement with escitalopram. Similar combinations of variables predicted remission with area under the curve 0.72, explaining approximately 15% of variance (pseudo R(2)) in who achieves remission, with strong contributions from body mass index, appetite, interest-activity symptom dimension and anxious-somatizing depression subtype. Escitalopram-specific outcome prediction was more accurate than generic outcome prediction, and reached effect sizes that were near or above a previously established benchmark for clinical significance. Outcome prediction on the nortriptyline arm did not significantly differ from chance. These results suggest that easily obtained demographic and clinical variables can predict therapeutic response to escitalopram with clinically meaningful accuracy, suggesting a potential for individualized prescription of this antidepressant drug.

    Selective serotonin reuptake inhibitors (SSRIs) are the most widely used antidepressants, but the efficacy of the treatment varies significantly among individuals. It is believed that complex genetic mechanisms play a part in this variation. We have used a network based approach to unravel the in...... genes involved in calcium homeostasis.

    Full Text Available The use of antidepressant drugs for the management of chronic pelvic pain has been supported in the past. This study aimed to evaluate the available evidence for the efficacy and acceptability of antidepressant drugs in the management of urological chronic pelvic pain. Studies were selected through a comprehensive literature search. We included all types of study designs due to the limited evidence. Studies were classified into levels of evidence according to their design. Ten studies were included with a total of 360 patients. Amitriptyline, sertraline, duloxetine, nortriptyline, and citalopram are the antidepressants that have been reported in the literature. Only four randomized controlled trials (RCTs were identified (two for amitriptyline and two for sertraline with mixed results. We conclude that the use of antidepressants for the management of chronic urological pelvic pain is not adequately supported by methodologically sound RCTs. From the existing studies amitriptyline may be effective in interstitial cystitis but publication bias should be considered as an alternative explanation. All drugs were generally well tolerated with no serious events reported.

    Patient perspectives on antidepressant treatment and physician attention, and responses toward these in consultations with patients diagnosed with depression, are rarely studied. We analyzed video-recorded consultations with general practitioners (GPs) and psychiatrists. We used conversation analysis and systemic functional linguistics and found that the perspectives patients expressed related to the possibility of achieving, and the inability to retain, a sense of agency. Patients also presented indirect expressions of shame and expressions suggesting alienation toward medical treatment. GPs attended to patient perspectives by talking about medication indirectly. When patients expressed their perspectives, GPs responded by being nonauthoritative but also without prompting patients to elaborate on their reflections. Psychiatrists responded authoritatively and never urged patients to reflect on their perspectives. Shared decision making did not take place because physicians did not explore patients' perspectives in depth or offer their expertise by taking these perspectives into consideration.

    Thymol, a bioactive monoterpene isolated from Thymus vulgaris, has displayed inspiring neuroprotective properties. The present study was designed to evaluate the antidepressant-like effects of thymol on a chronic unpredictable mild stress (CUMS) model of depression in mice and explore the underlying mechanisms. It was observed that thymol treatment (15 mg/kg and 30 mg/kg) significantly reversed the decrease of sucrose consumption, the loss of body weight, the reduction of immobile time in the tail suspension tests (TST) and forced swimming tests (FST) induced by CUMS paradigm. The levels of norepinephrine (NE) and serotonin (5-HT) in the hippocampus decreased in the CUMS-treated mice. Chronic treatments with thymol significantly restored the CUMS-induced alterations of monoamine neurotransmitters in the hippocampus. Our results further demonstrated that thymol administration negatively regulated the induction of proinflammatory cytokines including interleukin (IL)-1β, IL-6, and tumor necrosis factor-α in CUMS mice. Furthermore, thymol inhibited the activation of nod-like receptor protein 3 (NLRP3) inflammasome and its adaptor, and subsequently decreased the expression of caspase-1. In sum, our findings suggested that thymol played a potential antidepressant role in CUMS mice model through up-regulating the levels of central neurotransmitters and inhibiting the expressions of proinflammatory cytokines, which might provide potential for thymol in the light of opening up new therapeutic avenues for depression.

Methods Multicenter, non-interventional study in adult outpatients with a DSM-IV-TR diagnosis of MDD and inadequate response to first-line antidepressant medication. Multiple logistic regression analyses were performed to identify independent factors associated with the adoption of a specific second-line strategy.

The most common strategies were: switching antidepressant medication (39.6%, augmentation (18.8%, and combination therapy (17.9%. Atypical antipsychotic drugs were the most commonly used agent for augmenting antidepressant effect. The presence of psychotic symptoms and the number of previous major depressive episodes were associated with the adoption of augmenting strategy (OR = 3.2 and 1.2, respectively. Conclusion The switch to another antidepressant agent was the most common second-line therapeutic approach. Psychiatrists chose augmentation based on a worse patients’ clinical profile (number of previous episodes and presence of psychotic symptoms.

    This study was designed to evaluate antidepressant-like activity of gallic acid in Swiss young male albino mice subjected to unpredictable chronic mild stress and to explore the possible underlying mechanisms for this activity. Gallic acid (5, 10, 20 mg/kg, i.p.) and fluoxetine (10 mg/kg, i.p.) per se were administered daily to unstressed mice and other groups of mice subjected to unpredictable mild stress, 30 min after the injection for 21 successive days. The antidepressant-like activity was evaluated using forced swim test (FST) and sucrose preference test. Stress significantly increased immobility period of mice in FST. Gallic acid (10 and 20 mg/kg, i.p.) and fluoxetine significantly decreased immobility period of unstressed and stressed mice in FST and prevented the stress-induced decrease in sucrose preference, indicating significant antidepressant-like activity. There was no significant effect on locomotor activity of the mice by the drugs. Gallic acid (10 and 20 mg/kg, i.p.) significantly decreased Monoamine oxidase-A (MAO-A) activity, malondialdehyde levels, and catalase activity in unstressed mice; and significantly prevented the stress-induced decrease in reduced glutathione and catalase activity; and also significantly prevented stress-induced increase in MAO-A activity, malondialdehyde levels, plasma nitrite, and corticosterone levels. Thus, gallic acid showed antidepressant-like activity in unstressed and stressed mice probably due to its antioxidant activity and through inhibition of MAO-A activity and decrease in plasma nitrite levels. In addition, gallic acid also showed antidepressant-like activity in stressed mice probably through decrease in plasma corticosterone levels.

    Abstract Objectives. The aim of this study was to compare efficacy of antidepressant monotherapies and combinations of antidepressants in the treatment of resistant patients in current clinical practice. Methods. We reviewed chart documents of resistant depressive inpatients treated at least 4 weeks with a new treatment. Depressive symptoms and clinical status were assessed using Montgomery and Åsberg Depression Rating Scale (MADRS), Beck Depression Inventory-Short Form and Clinical Global Impression at the baseline, week 2 and in the end of treatment. Results. We identified 81 patients (27 with combinations and 51 with monotherapies) that were suitable for analyses. The combination group achieved higher reduction of MADRS score (14.6 vs 10.2 pts., p=0.02) and response rate (≥ 50% reduction of MADRS, 67% vs 39%, p=0.03). Number needed to treat for response was 4. Conclusions. Based on our results, we suggest that combination of antidepressants might be more effective than monotherapy in clinical practice.

    Current pharmacotherapy of schizophrenia remains unsatisfactory with little hope for complete functional restoration in patients once the disease has developed. A preventive approach based on intervention in the prodromal stage of the disease aiming to preserve functional integrity by halting the progress of the disease is therefore extremely attractive. Here, we investigated the effects of preventive antipsychotic or antidepressant drug treatment in a well-established neurodevelopmental mouse model of multiple schizophrenia-related abnormalities. Pregnant mice on gestation day 9 were exposed to the viral mimic polyriboinosinic-polyribocytidylic acid (2 mg/kg, intravenously) or corresponding vehicle treatment, and the resulting offspring from both prenatal treatment conditions were subjected to chronic antipsychotic (haloperidol or clozapine), antidepressant (fluoxetine), or placebo treatment during the periadolescent stage of development. The effects of the preventive pharmacotherapy on behavioral and pharmacological functions were then investigated in adulthood using paradigms relevant to schizophrenia, namely prepulse inhibition, latent inhibition, and sensitivity to psychostimulant drugs. We show that periadolescent treatment with the reference antipsychotic and antidepressant drugs can successfully block the emergence of multiple psychosis-related behavioral and pharmacological abnormalities in subjects predisposed to adult brain pathology by exposure to prenatal immune challenge. At the same time, however, our study reveals numerous negative influences of the early pharmacological intervention on normal behavioral development in control subjects. Hence, even though preventive pharmacotherapy may be beneficial in individuals with predisposition to psychosis-related brain dysfunctions, chronic antipsychotic or antidepressant drug treatment in false-positive subjects is associated with substantial risk for long-term behavioral disturbances in adulthood.

The alterations in brain circuit dynamics that can arise from stress exposure and underlie therapeutic actions of ADs remain, however, poorly understood. Here, enabled by a recently developed voltage-sensitive dye imaging assay in mouse brain slices, we examined the impact of chronic stress and concentration-dependent effects of eight clinically used ADs (belonging to different chemical/funct...

    The effect of treating comorbid depression to achieve optimal management of chronic obstructive pulmonary disease (COPD) has not yet empirically tested. We examined the association between antidepressant treatment and use of and adherence to COPD maintenance medications among patients with new-onset COPD and comorbid depression. Using 2006-2012 Medicare data, this retrospective cohort study identified patients with newly diagnosed COPD and new-onset major depression. Two exposures-antidepressant use (versus non-use) and adherence measured by proportion of days covered (PDC) (PDC ≥0.8 versus <0.8)-were assessed quarterly. We used marginal structural models to estimate the effects of prior antidepressant use and adherence on subsequent COPD maintenance inhaler use and adherence outcomes, accounting for time-varying confounders. A total of 25 458 COPD-depression patients, 82% with antidepressant treatment, were followed for a median of 2.5 years. Nearly half (48%) used at least 1 COPD maintenance inhaler in any given quarter; among users, 3 in 5 (61%) had a PDC of <0.8. Compared to patients with no antidepressant treatment, those with antidepressant use were more likely to use (relative ratio [RR] = 1.15, 95% confidence interval [CI] = 1.12- 1.17) and adhere to (RR = 1.08, 95% = 1.03-1.14) their COPD maintenance inhalers. Patients who adhered to antidepressant treatment were more likely to use and adhere to COPD maintenance inhalers. Regularly treated depression may increase use of and adherence to necessary maintenance medications for COPD. Antidepressant treatment may be a key determinant to improving medication-taking behaviors among COPD patients comorbid with depression. Copyright © 2017 John Wiley & Sons, Ltd.

    Biomarkers to predict clinical outcomes early during the treatment of major depressive disorder (MDD) could reduce suffering and improve outcomes. A quantitative electroencephalogram (qEEG) biomarker, the Antidepressant Treatment Response (ATR) index, has been associated with outcomes of treatment with selective serotonin reuptake inhibitor antidepressants in patients with MDD. Here, we report the results of a post hoc analysis initiated to evaluate whether the ATR index may also be associated with reboxetine treatment outcome, given that its putative mechanism of action is via norepinephrine reuptake inhibition (NRI). Twenty-five adults with MDD underwent qEEG studies during open-label treatment with reboxetine at doses of 8 to 10 mg daily for 8 weeks. The ATR index calculated after 1 week of reboxetine treatment was significantly associated with overall Hamilton Depression Rating Scale (HAM-D) improvement at week 8 (r=0.605, P=.001), even after controlling for baseline depression severity (P=.002). The ATR index predicted response (≥50% reduction in HAM-D) with 70.6% sensitivity and 87.5% specificity, and remission (final HAM-D≤7) with 87.5% sensitivity and 64.7% specificity. These results suggest that the ATR index may be a useful biomarker of clinical response during NRI treatment of adults with MDD. Future studies are warranted to investigate further the potential utility of the ATR index as a predictor of noradrenergic antidepressant treatment response.

  18. [Threshold of Application of Antidepressant Drugs for Treatment of Depressive Disorder].

    In recent years, along with the expansion of medical care for depressive disorder, there has been much controversy regarding the application of antidepressant drugs for its treatment. The aim of this paper is to consider critical issues concerning the threshold of application of antidepressant drugs for the treatment of depression. It was formerly important to diagnose the 'quality' of depression (melancholia or non-melancholia) in order to choose antidepressant treatment, whereas an assessment of the 'quantity' of depression (severity of symptoms) is crucial today to decide on the threshold. Recent guidelines for the treatment of major depressive disorder do not positively recommend the use of medication for the treatment of mild depression. The guidelines published by the Japanese Society of Mood Disorders also state that doctors have to give priority to treatments avoiding medication, although the effectiveness of antidepressant drugs for mild depression is controversial. Actually, in a clinical setting, doctors have to understand the conditions of individual cases and cope with many issues, such as a risk of suicide, comorbidity of other psychiatric disorders, target symptoms of pharmacotherapy, and choices of classes and doses of antidepressant drugs. The threshold of application of antidepressant drugs for the treatment of depression may vary according to the doctor-patient relationship and surrounding conditions. Doctors are required to provide treatment options other than pharmacotherapy.

    This report assessed whether hospital ward overcrowding predicts antidepressant use among hospital staff. The extent of hospital ward overcrowding was determined using administrative records of monthly bed occupancy rates between 2000 and 2004 in 203 somatic illness wards in 16 Finnish hospitals providing specialized health care. Information on job contracts for personnel was obtained from the employers' registers. Comprehensive daily data on purchased antidepressant prescriptions (World Health Organization's Anatomical Therapeutic Chemical classification code N06A) for nurses (N=6,699) and physicians (N=641) was derived from national registers. Cox proportional hazards models were used to examine the association between bed occupancy rate and subsequent antidepressant treatment. Monthly bed occupancy rates were used as a time-dependent exposure that could change in value over the course of observation. Hazard ratios were adjusted for sex, age, occupation, type and length of employment contract, hospital district, specialty, and calendar year. Exposure over 6 months to an average bed occupancy rate over 10% in excess of the recommended limit was associated with new antidepressant treatment. This association followed a dose-response pattern, with increasing bed occupancy associated with an increasing likelihood of antidepressant use. There was no evidence of reverse causality; antidepressant treatment among employees did not predict subsequent excess bed occupancy. The increased risk of antidepressant use observed in this study suggests that overcrowding in hospital wards may have an adverse effect on the mental health of staff.

    Chronic pain and depression frequently coexist in clinical setting, and current clinical treatments for this comorbidity have shown limited efficacy. Triptolide (T10), an active component of Tripterygium wilfordii Hook F., has been demonstrated to exert strong analgesic activities in experimental pain models, but whether it possesses anti-depressive actions remains unknown. Using a depression comorbidity of chronic pain rat model induced by spinal nerve ligation (SNL), we investigated the potency of T10 for the treatment of comorbid depression in comparison with a widely used antidepressant, fluoxetine (FLX). Concomitant neuroinflammation changes were also examined in the hippocampus. The results showed that prophylactic and reversal treatments with T10 dose-dependently (30, 100, 300μg/kg) inhibited the depression-like behaviors (DLB) assessed by the forced swim test, sucrose preference test and body weight measurement. The anti-depressive efficacy of T10 at 300μg/kg was significantly stronger than that of FLX at 18mg/kg. T10 at all three doses exhibited more efficient analgesic effects than FLX at 18mg/kg. The combined application of T10 with FLX markedly augmented the effects of T10 or FLX per se, with the facilitating effects of T10 at 30μg/kg being most prominent. In addition, nerve injury caused the activation of microglia and p38 MAPK, the upregulation of IL-1β and TNF-α as well as the downregulation of IL-10 in the hippocampus at postoperative week (POW) 3. These neuroinflammatory responses were reversed by subchronic treatment with T10. Taken together, these results demonstrate that T10 possesses potent anti-depressive function, which is correlated with its immunoregulation in the hippocampus. The combination of a low dose of T10 with FLX may become a more effective medication strategy for the treatment of comorbid depression and chronic pain.

    This randomized, 6-week, open-label study compared efficacy of CAD and antidepressant monotherapies (ADM) that had been chosen according to clinical judgment of the attending psychiatrist. A total of 60 inpatients (intent-to-treat analysis) with depressive disorder (≥ 1 unsuccessful antidepressant treatment) were randomly assigned to the interventions. The responders who completed the acute phase of study, were evaluated for relapse within 2 months of follow-up treatment. The primary outcome measure was change in the Montgomery-Åsberg Depression Rating Scale (MADRS) and response was defined as a ≥ 50% reduction of MADRS score. Mean changes in total MADRS score from baseline to week 6 for patients in both treatment modalities were not different (ADM = 13.2 ± 8.6 points; CAD = 14.5 ± 9.5 points; P = 0.58). The analysis of covariance performed for significantly higher value of imipramine equivalent dose in CAD group showed only a non-significant between-group difference for total MADRS change (P = 0.17). There were also no differences between groups in response rate (ADM = 48%; CAD = 58%) and number of drop-outs in acute treatment as well as proportion of responders' relapses in the follow-up. Both treatment modalities produced clinically relevant reduction of depressive symptomatology in acute treatment of patients with resistant depression and their effect was comparable.

    Full Text Available Abstract Background Adherence has recently been suggested to be divided into these two components: persistence (i.e., whether patients continue treatment or not and compliance (i.e., whether patients take doses as instructed. However, no study has yet assessed these two clinically relevant components at the same time in adherence to antidepressant treatment in the clinical outpatient setting. Methods In this retrospective chart-review, 6-month adherence to antidepressants was examined in 367 outpatients with a major depressive disorder (ICD-10 (170 males; mean ± SD age 37.6 ± 13.9 years, who started antidepressant treatment from April 2006 through March 2007. Additionally, we evaluated Medication Possession Rate (MPR, defined as the total days a medication was dispensed to patients divided by the treatment period. Results Only 161 patients (44.3% continued antidepressant treatment for 6 months. Among 252 patients who discontinued their initial antidepressant, 63.1% of these patients did so without consulting their physicians. Sertraline use was associated with a higher persistence rate at month 6 (odds ratio 2.59 in comparison with sulpiride, and the use of anxiolytic benzodiazepines had a positive effect on persistence to antidepressant treatment only at month 1 (odds ratio 2.14. An overall MPR was 0.77; 55.6% of patients were considered compliant (i.e., a MPR of ≥ 0.8. Conclusion Given a high rate of antidepressant discontinuation without consulting their physicians, closer communication between patients and their physicians should be encouraged. Although the use of anxiolytic benzodiazepines was associated with a higher persistence to antidepressant treatment at month 1, the use of these drugs should be avoided as a rule, given their well-known serious adverse effects.

    We present two cases of treatment-resistant depression that improved with recognition and correction of the underlying medical etiology of vitamin B12 deficiency. Supplementations of vitamin B12 to the same antidepressant regimen that the patient had not responded earlier led to response. Two male subjects who were vegetarians presented with long-standing histories of depression and had not responded to three adequate trials of antidepressants. Upon investigation, the authors found that the subjects had low vitamin B12 levels. Both cases improved with supplementation of vitamin B12. Subjects with depression who do not respond to conventional antidepressants should be evaluated for nutritional factors.

    Depression is a serious mental disorder in the world, but the underlying mechanisms remain unclear and the effective cures are scarce. Iptakalim (Ipt), an ATP-sensitive potassium (K-ATP) channel opener that can cross the blood-brain barrier freely, has been demonstrated to inhibit neuro-inflammation and enhance adult hippocampal neurogenesis. But it is unknown whether Ipt is beneficial to therapy of depression by modulating neurogenesis and neuro-inflammation. This study aimed to determine the potential antidepressant efficacy of Ipt in a chronic mild stress (CMS) mouse model of depression. We showed that treatment with Ipt (10 mg/kg/day, i.p) for 4 wk restored the decrease of sucrose preference and shortened the immobile time in forced swimming tests (FST) and tail suspension tests (TST) in CMS model mice. We further found that Ipt reversed the CMS-induced reduction of the adult hippocampal neurogenesis and improved cerebral insulin signalling in the CMS mice. Furthermore, Ipt negatively regulated nod-like receptor protein 3 (NLRP3) expression and, in turn, inhibited microglia-mediated neuro-inflammation by suppressing the activation of NLRP3-inflammasome/caspase-1/interleukin 1β axis in the hippocampus of CMS mice. Taken together, our findings demonstrate that Ipt plays a potential antidepressant role in CMS model mice through regulating neuro-inflammation and neurogenesis, which will provide potential for Ipt in terms of opening up novel therapeutic avenues for depression.

    Full Text Available The effects of antenatal depression and antidepressant treatment during pregnancy on both mother and child are vigorously studied, but the underlying biology for these effects is largely unknown. The placenta plays a crucial role in the growth and development of the fetus. We performed a gene expression study on the fetal side of the placenta to investigate gene expression patterns in mothers with antenatal depression and in mothers using antidepressant treatment during pregnancy.Placental samples from mothers with normal pregnancies, from mothers with antenatal depression, and from mothers using antidepressants were collected. We performed a pilot microarray study to investigate alterations in the gene expression and selected several genes from the microarray for biological validation with qPCR in a larger sample.In mothers with antenatal depression 108 genes were differentially expressed, whereas 109 genes were differentially expressed in those using antidepressants. Validation of the microarray revealed more robust gene expression differences in the seven genes picked for confirmation in antidepressant-treated women than in depressed women. Among the genes that were validated ROCK2 and C12orf39 were differentially expressed in both depressed and antidepressant-treated women, whereas ROCK1, GCC2, KTN1, and DNM1L were only differentially expressed in the antidepressant-treated women. In conclusion, antenatal depression and antidepressant exposure during pregnancy are associated with altered gene expression in the placenta. Findings on those genes picked for validation were more robust among antidepressant-treated women than in depressed women, possibly due to the fact that depression is a multifactorial condition with varying degrees of endocrine disruption. It remains to be established whether the alterations found in the gene expression of the placenta are found in the fetus as well.

    Recent data suggests that the glutamatergic system is involved in the pathophysiology and treatment of major depressive disorder (MDD) and that the N-methyl-D-aspartate (NMDA) receptor is a potential target for antidepressant drugs. The magnesium ion blocks the ion channel of the NMDA receptor and prevents its excessive activation. Some preclinical and clinical evidence suggests also that magnesium may be useful in the treatment of depression. The present study investigated the effect of magnesium treatment (10, 15 and 20 mg/kg, given as magnesium hydroaspartate) in the chronic mild stress (CMS) model of depression in rats. Moreover, the effect of CMS and magnesium (with an effective dose) on the level of the proteins related to the glutamatergic system (GluN1, GluN2A, GluN2B and PSD-95) in the hippocampus, prefrontal cortex (PFC) and amygdala were examined. A significant reduction in the sucrose intake induced by CMS was increased by magnesium treatment at a dose of 15 mg/kg, beginning from the third week of administration. Magnesium did not affect this behavioural parameter in the control animals. CMS significantly increased the level of the GluN1 subunit in the amygdala (by 174%) and GluN2A in the hippocampus (by 191%), both of which were significantly attenuated by magnesium treatment. Moreover, magnesium treatment in CMS animals increased the level of GluN2B (by 116%) and PSD-95 (by 150%) in the PFC. The present results for the first time demonstrate the antidepressant-like activity of magnesium in the animal model of anhedonia (CMS), thus indicating the possible involvement of the NMDA/glutamatergic receptors in this activity.

    Dextromethorphan (DM) may have ketamine—like rapid—acting, treatment—resistant, and conventional antidepressant effects.1,2 This reports our initial experience with DM in unipolar Major Depressive Disorder (MDD). A patient with treatment—resistant MDD (failing adequate trials of citalopram and vortioxetine) with loss of antidepressant response (to fluoxetine and bupropion) twice experienced a rapid—acting antidepressant effect within 48 hours of DM administration and lasting 7 days, sustained up to 20 days with daily administration, then gradually developing labile loss of antidepressant response over the ensuing 7 days. Upon full relapse in DSM-5 MDD while taking 600 mg/day of the strong CYP2D6 inhibitor bupropion XL, a 300 mg oral loading dose of DM was given, followed by 60 mg po bid after an additional dose—finding period, without side effects. DM exhibited a ketamine—like rapid—acting antidepressant effect, thought to be mediated by mTOR activation (related to NMDA PCP site antagonism, sigma-1 and beta adrenergic receptor stimulation) and 5HTT inhibition, resulting in AMPA receptor trafficking, and dendritogenesis, spinogenesis, synaptogenesis, and increased neuronal survival (related to NMDA antagonism and sigma-1 and mTOR signaling). This report appears to be the first report of a rapid—acting effect in unipolar MDD and adds to antidepressant effects observed in the retrospective chart review of 77 patients with Bipolar II Disorder (Kelly and Lieberman 2014). If replicated, there is some reason to think that the administration of other agents with DM, such as lithium or D-cycloserine, might prolong the duration of the rapid-antidepressant effect.

    Full Text Available Pleasurable sexual activity is an essential component of many human relationships, providing a sense of physical, psychological, and social well-being. Epidemiological and clinical studies show that depressive symptoms and depressive illness are associated with impairments in sexual function and satisfaction, both in untreated and treated patients. The findings of randomized placebo-controlled trials demonstrate that most of the currently available antidepressant drugs are associated with the development or worsening of sexual dysfunction, in a substantial proportion of patients. Sexual difficulties during antidepressant treatment often resolve as depression lifts but can endure over long periods and may reduce self-esteem and affect mood and relationships adversely. Sexual dysfunction during antidepressant treatment is typically associated with many possible causes, but the risk and type of dysfunction vary with differing compounds and should be considered when making decisions about the relative merits and drawbacks of differing antidepressants. A range of interventions can be considered when managing patients with sexual dysfunction associated with antidepressants, including the prescription of phosphodiesterase-5 inhibitors, but none of these approaches can be considered “ideal.” As treatment-emergent sexual dysfunction is less frequent with certain drugs, presumably related to differences in their pharmacological properties, and because current management approaches are less than ideal, a reduced burden of treatment-emergent sexual dysfunction represents a tolerability target in the development of novel antidepressants.

Animals were divided into six groups (n=6 for treatment with water, genistein, or amitriptyline, either alone or in combination for ten days. Animals were subjected to locomotor activity testing; tail suspension test (TST; and forced swim test (FST and immobility time was recorded on day one and day ten. Acute treatment of all treatment groups did not significantly reduce the immobility time (p>0.05. Chronic treatment of combination of genistein (10 mg/kg and amitriptyline (5 mg/kg and 10 mg/kg significantly reduced the immobility time as compared to control group (p<0.001 and was comparable to amitriptyline alone (10 mg/kg. However, no changes in anti-immobility activity in combination of subeffective doses of genistein (5 mg/kg and amitriptyline (5 mg/kg were observed. Genistein at its standard dose (10 mg/kg rendered synergistic effects in combination with subeffective dose of amitriptyline (5 mg/kg and additive effects in combination with therapeutic dose of amitriptyline (10 mg/kg.

    Long-term treatment with antidepressants can lessen the symptoms of depression, but health-related crises-such as a cancer diagnosis-may disrupt ongoing depression care. The study aims to estimate the effect of receiving a breast cancer diagnosis on antidepressant adherence among women with depression. Using SEER-Medicare administrative claims, we identified women aged 65+ with newly diagnosed breast cancer between 2008 and 2011, who were diagnosed with depression and used antidepressants during the year before pre-diagnosis year. We compared antidepressant adherence among women with breast cancer to similar women without cancer using generalized estimation equations. Antidepressant adherence was estimated using the proportion of days covered 1 year before and after the index date. We included 1142 women with breast cancer and pre-existing depression and 1142 matched non-cancer patients with pre-existing depression. Mean antidepressant adherence was similar for both groups in the year before and after the index date (all around 0.71); adherence decreased by approximately 0.01 following breast cancer diagnosis in cancer group, with similar reductions among non-cancer group (p = 0.19). However, substantial proportion of patients had inadequate adherence to antidepressants in the post-diagnosis period, and almost 40% of patients in each group discontinued antidepressants over the study period. Antidepressant adherence was not associated with receiving a breast cancer diagnosis beyond what would have been expected in a similar cohort of women without cancer; however, adherence was poor among both groups. Ensuring adequate ongoing depression care is important to improve cancer care and patient quality of life in the long term. Copyright © 2017 John Wiley & Sons, Ltd.

  14. The effect of antidepressant medication treatment on serum levels of inflammatory cytokines: a meta-analysis.

    Hannestad, Jonas; DellaGioia, Nicole; Bloch, Michael

    2011-11-01

    Serum levels of inflammatory cytokines, for example, tumor necrosis factor alpha (TNFα), interleukin-6 (IL-6), and IL-1 beta (IL-1β), are elevated in subjects with major depressive disorder (MDD). The reason why this occurs is unclear. Elevated levels of inflammatory cytokines could be a result of brain dysfunction in MDD. It is also possible that inflammatory cytokines contribute to depressive symptoms in MDD. If the first assumption is correct, one would expect levels to normalize with resolution of the depressive episode after treatment. Several studies have measured changes in cytokine levels during antidepressant treatment; however, the results vary. The purpose of this study was to pool all available data on changes in serum levels of TNFα, IL-6, and IL-1β during antidepressant treatment to determine whether these levels change. Studies were included if they used an approved pharmacological treatment for depression, patients had a diagnosis of MDD, and serum levels of TNFα, IL-6, and/or IL-1β were measured before and after treatment. Twenty-two studies fulfilled these criteria. Meta-analysis of these studies showed that, overall, while pharmacological antidepressant treatment reduced depressive symptoms, it did not reduce serum levels of TNFα. On the other hand, antidepressant treatment did reduce levels of IL-1β and possibly those of IL-6. Stratified subgroup analysis by class of antidepressant indicated that serotonin reuptake inhibitors may reduce levels of IL-6 and TNFα. Other antidepressants, while efficacious for depressive symptoms, did not appear to reduce cytokine levels. These results argue against the notion that resolution of a depressive episode is associated with normalization of levels of circulating inflammatory cytokines; however, the results are consistent with the possibility that inflammatory cytokines contribute to depressive symptoms and that antidepressants block the effects of inflammatory cytokines on the brain.

    Objective Chronic cough remains a challenging condition, especially in cases where it persists despite comprehensive medical management. For these particular patients, there appears to be an emerging role for behavior modification therapy. We report a series of patients with refractory chronic cough to assess if there is any benefit of adding behavioral therapy to their treatment regimen. Study Design A case series with planned chart review of patients treated for chronic cough. Setting The review was performed with an outpatient electronic health record system at a tertiary care center. Subjects and Methods The charts of all patients treated for chronic cough by a single laryngologist over a 30-month period were analyzed. Patients' response to treatment and rate of cough improvement were assessed for those with refractory chronic cough who underwent behavior modification therapy. Results Thirty-eight patients with chronic cough were initially treated empirically for the most common causes of cough, of which 32% experienced improvement. Nineteen patients who did not significantly improve with medical management underwent behavior modification therapy with a speech-language pathologist. Of these patients, 84% experienced resolution or marked improvement of their symptoms. Conclusion Behavioral therapy may be underutilized in practice and could lead to improvement of otherwise recalcitrant cough.

  16. [Chronic prostatitis: a new paradigm of treatment].

    This paper proposes health care recommendations for men with chronic prostatitis (CP) taking into account etiopathogenesis and the clinical presentation of the disease. The proposal is based on the experience of federal and regional clinics of urology and gynecology, respective departments for postgraduate education and on the analysis of scientific literature. It is shown that managing patients with CP requires consideration of factors beyond the traditional practice of urology. The author validates the need to use the modern prostatitis classification UPOINT instead of the traditional NIH NIDDK (1995) to increase the effectiveness of treatment. It is demonstrated that the concurrent use of medications and non-pharmacological treatments aimed at different aspects of the state improve the treatment effectiveness. Indications are refined for medical and non-pharmacological treatments: antibiotics, alpha-blockers, anticholinergic agents, analgesics, antidepressants, herbal remedies, pelvic floor physiotherapy, psychotherapy. The shortcomings and mistakes of existing guidelines/standards are analyzed.

    Natural products have been widely reported as effective therapeutic alternatives for treatment of depression. Sanyuansan is a compound recipe composed of ginseng total saponins, fish oil, and valeriana. The aims of this study were to validate whether Sanyuansan has antidepressant-like effects through acute behavioral tests including the forced swimming test (FST), tail suspension test (TST), locomotor activity test, and chronic mild stress (CMS) mice model of depression. C57BL/6 mice were given oral administration of 30 mg/kg imipramine, Sanyuansan, and saline, respectively. The acute behavioral tests including the TST, FST, and locomotor activity test were done after the administration of drugs for consecutively three times (24 hours, 1 hour, and 0.5 hour prior to the tests). Furthermore, the sucrose preference and the serum corticosterone level of mice in the CMS model were examined. Sanyuansan only at 900 mg/kg markedly reduced immobility time in the TST compared with the saline-treated group of mice. Sanyuansan at doses of 225 mg/kg, 450 mg/kg, and 900 mg/kg significantly reduced immobility time of mice in the FST. Sanyuansan reversed the CMS-induced anhedonia and hyperactivation of the hypothalamus-pituitary-adrenal axis. In addition, our results showed that neither imipramine nor Sanyuansan at any dosage increased spontaneous motor activity. These results suggested that Sanyuansan induced significant antidepressant-like effects in mice in both acute and chronic animal models, which seemed unlikely to be attributed to an increase in locomotor activities of mice, and had no sedative-like effects.

    We have previously reported that chronic imipramine and electroconvulsive treatments increase the α(1A)-adrenoceptor (but not the α(1B) subtype) mRNA level and the receptor density in the rat cerebral cortex. Furthermore, we have also shown that chronic treatment with citalopram does not affect the expression of either the α(1A)- or the α(1B)-adrenoceptor, indicating that the previously observed up-regulation of α(1A)-adrenoceptor may depend on the noradrenergic component of the pharmacological mechanism of action of these antidepressants. Here, we report that previous noradrenergic depletion with DSP-4 (50 mg/kg) (a neurotoxin selective for the noradrenergic nerve terminals) significantly attenuated the increase of α(1A)-adrenoceptor mRNA induced by a 14-day treatment with imipramine (IMI, 20 mg/kg, ip) and abolished the effect of electroconvulsive shock (ECS, 150 mA, 0.5 s) in the prefrontal cortex of the rat brain. The changes in the receptor protein expression (as reflected by its density) that were induced by IMI and ECS treatments were differently modulated by DSP-4 lesioning, and only the ECS-induced increase in α(1A)-adrenoceptor level was abolished. This study provides further evidence corroborating our initial hypothesis that the noradrenergic component of the action of antidepressant agents plays an essential role in the modulation of α(1A)-adrenoceptor in the rat cerebral cortex.

    The aim of this study was to determine the effects and underlying mechanism of aripiprazole (APZ) augmentation for cilostazol (CLS)-treated post-ischemic stroke mice that were exposed to chronic mild stress (CMS). Compared to treatment with either APZ or CLS alone, the combined treatment resulted in a greater reduction in depressive behaviors, including anhedonia, despair-like behaviors, and memory impairments. This treatment also significantly reduced atrophic changes in the striatum, cortex, and midbrain of CMS-treated ischemic mice, and inhibited neuronal cell apoptosis, particularly in the striatum and the dentate gyrus of the hippocampus. Greater proliferation of neuronal progenitor cells was also observed in the ipsilateral striatum of the mice receiving combined treatment compared to mice receiving either drug alone. Phosphorylation of the cyclic adenosine monophosphate response element binding protein (CREB) was increased in the striatum, hippocampus, and midbrain of mice receiving combined treatment compared to treatment with either drug alone, particularly in the neurons of the striatum and hippocampus, and dopaminergic neurons of the midbrain. Our results suggest that APZ may augment the antidepressant effects of CLS via co-regulation of the CREB signaling pathway, resulting in the synergistic enhancement of their neuroprotective effects.

    The use of antidepressants in treatment of depression in course of bipolar disorders (BD) is controversial. In case of no improvement during monotherapy with mood stabilizer, the use of antidepressants is often necessary. The safety of this group (in context of phase change, mixed states and rapid cycling) is essential and is the subject of many research. In the paper, the authors review the literature concerning efficacy and safety of use of antidepressants in the treatment of affective disorders and long-term impact on the course of the disease. Selection of articles have been made by searching the Medline and Pubmed databases using keywords: antidepressant drugs, bipolar depression, bipolar disorder, efficacy, safety, mania, hypomania. The risk of mania is greater in bipolar disorder type I, than in type II or during treatment with Tricyclic antidepressants (TCAs) and treatment with venlafaxine. The use of SSRIs and bupropion is associated with a relatively small increase of phase change risk. There are different opinions concerning recommended duration of antidepressant treatment. Generally antidepressant use should end after 2-3 months of remission, the risk of recurrence of depression after discontinuation of antidepressants is, however, higher than in case of continuation. In BD type II or BD spectrum, antidepressant monotherapy is allowed in severe depression. In bipolar disorder type I and in case of phase change after antidepressants use in the past, use of antidepressants should be very cautious. Antidepressants are contraindicated in rapid cycling and in mixed episodes. Further work is needed to evaluate the efficacy and safety of antidepressants use.

    Generalized Anxiety Disorder (GAD) is a persistent condition characterized by chronic anxiety, exaggerated worry and tension, mainly comorbid with Major Depressive Disorder (MDD). Currently, selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors are recommended as first-line treatment of GAD. However, some patients may not respond to the treatment or discontinue due to adverse effects. Vortioxetine (VRX) is a multimodal antidepressant with a unique mechanism of action, by acting as 5-HT3A, 5-HT1D and 5-HT7 receptor antagonist, partial agonist at the 5-HT1A and 5-HT1B receptors and inhibitor at the 5-HT transporter. Preliminary clinical trials showed contrasting findings in terms of improvement of the anxiety symptomatology and/or cognitive impairment. Here, we aim to systematically review the evidence currently available on the efficacy, safety and tolerability of VRX in the treatment of GAD. The generalizability of results on the efficacy of VRX in patients with anxiety symptomatology and GAD is limited due to few and contrasting RCTs so far available. Only two studies, of which one prevention relapse trial, reported a significant improvement in anxiety symptomatology compared to three with negative findings.

    Context Previous studies have found that few chronically depressed patients remit with antidepressant medications alone. Objective To determine the role of adjunctive psychotherapy in the treatment of chronically depressed patients with less than complete response to an initial medication trial. Design This trial compared 12 weeks of (1) continued pharmacotherapy and augmentation with cognitive behavioral analysis system of psychotherapy (CBASP), (2) continued pharmacotherapy and augmentation with brief supportive psychotherapy (BSP), and (3) continued optimized pharmacotherapy (MEDS) alone. We hypothesized that adding CBASP would produce higher rates of response and remission than adding BSP or continuing MEDS alone. Setting Eight academic sites. Participants Chronically depressed patients with a current DSM-IV–defined major depressive episode and persistent depressive symptoms for more than 2 years. Interventions Phase 1 consisted of open-label, algorithm-guided treatment for 12 weeks based on a history of antidepressant response. Patients not achieving remission received next-step pharmacotherapy options with or without adjunctive psychotherapy (phase 2). Individuals undergoing psychotherapy were randomized to receive either CBASP or BSP stratified by phase 1 response, ie, as nonresponders (NRs) or partial responders (PRs). Main Outcome Measures Proportions of remitters, PRs, and NRs and change on Hamilton Scale for Depression (HAM-D) scores. Results In all, 808 participants entered phase 1, of which 491 were classified as NRs or PRs and entered phase 2 (200 received CBASP and MEDS, 195 received BSP and MEDS, and 96 received MEDS only). Mean HAM-D scores dropped from 25.9 to 17.7 in NRs and from 15.2 to 9.9 in PRs. No statistically significant differences emerged among the 3 treatment groups in the proportions of phase 2 remission (15.0%), partial response (22.5%), and non-response (62.5%) or in changes on HAM-D scores.

    Full Text Available Jie Yu Chu Fan capsule (JYCF is a new compounded Chinese herbal medicine for the treatment of depression. The present study was designed to explore the antidepressant effects and the possible mechanisms of JYCF by using chronic unpredictable mild stress (CUMS mouse model and comparing results to that of fluoxetine. Behavioral tests including an open field test, sucrose preference test and forced swim test were performed to evaluate the antidepressant effects of JYCF. The concentrations of monoamine neurotransmitters and metabolic products including norepinephrine (NE, 5-hydroxytryptamine (5-HT, dopamine (DA, 5-hydroxyindoleacetic acid (5-HIAA, homovanillic acid (HVA and 3,4-dihydroxyphenylacetic acid (DOPAC in the cerebral cortex and hippocampus of mice were determined by means of high performance liquid chromatography with electrochemical detection (HPLC-EC. The results show that a successful mouse CUMS model was established through 5 weeks of continuous unpredictable stimulation, as indicated by the significant decrease in sucrose preference and locomotor activity and increase in immobility time in the forced swim test. Chronic treatment of JYCF (1.25, 2.5 and 5 g/kg and fluoxetine (20 mg/kg significantly reversed the CUMS-induced behavioral abnormalities. JYCF (1.25, 2.5 and 5 g/kg significantly increased NE in CUMS mouse prefrontal cortex (P < 0.01, P < 0.01, P < 0.05 respectively and 5-HT in hippocampus (P < 0.05. In summary, our findings suggest that JYCF exerts comparable antidepressant-like effects to that of fluoxetine in CUMS mice. Besides, the antidepressant-like effect of JYCF is mediated by the increase of monoaminergic transmitters including 5-HT and NE.

    During the past decade, one of the most striking discoveries in the treatment of major depression was the clinical finding that a single infusion of a sub-anesthetic dose of the N-methyl-d-aspartate receptor antagonist ketamine produces a rapid (i.e. within a few hours) and long-lasting (i.e. up to two weeks) antidepressant effect in both treatment-resistant depressed patients and in animal models of depression. Notably, converging clinical and preclinical evidence support that responsiveness to antidepressant drugs is sex-differentiated. Strikingly, research regarding the antidepressant-like effects of ketamine has focused almost exclusively on the male sex. Herein we report that female C57BL/6J stress-naïve mice are more sensitive to the rapid and the sustained antidepressant-like effects of ketamine in the forced swim test (FST). In particular, female mice responded to lower doses of ketamine (i.e. 3mg/kg at 30 min and 5mg/kg at 24h post-injection), doses that were not effective in their male counterparts. Moreover, tissue levels of the excitatory amino acids glutamate and aspartate, as well as serotonergic activity, were affected in a sex-dependent manner in the prefrontal cortex and the hippocampus, at the same time-points. Most importantly, a single injection of ketamine (10mg/kg) induced sex-dependent behavioral effects in mice subjected to the chronic mild stress (CMS) model of depression. Intriguingly, female mice were more reactive to the earlier effects of ketamine, as assessed in the open field and the FST (at 30 min and 24h post-treatment, respectively) but the antidepressant potential of the drug proved to be longer lasting in males, as assessed in the splash test and the FST (days 5 and 7 post-treatment, respectively). Taken together, present data revealed that ketamine treatment induces sex-dependent rapid and sustained neurochemical and behavioral antidepressant-like effects in stress-naïve and CMS-exposed C57BL/6J mice.

    Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition among men of a wide age range, with detrimental effects on quality of life. The etiology, pathogenesis, and optimal treatment of CP/CPPS remain unknown, although progress has been made in these domains in recent years. A wide variety of pharmacologic and nonpharmacologic therapies have been studied in clinical trials, but most have shown limited efficacy in symptom alleviation. CP/CPPS is increasingly viewed as a condition that involves variable degrees of neuropathic pain. Medications such as gabapentin, pregabalin, memantine, and tricyclic antidepressants are often used in other neuropathic pain conditions and, therefore, are considered potential treatments for CP/CPPS. Few studies of these agents in patients with CP/CPPS have been reported, but future clinical trials should help to determine their utility and to characterize the pathogenetic mechanisms of pain in CP/CPPS. Combining treatment trials with biomarker, genomic, and imaging studies, in addition to epidemiologic and symptom-based assessments, will maximize the ability to probe disease etiology and pathogenesis, as well as identify effective treatment.

    Full Text Available Abstract This report describes a patient suffering from panic disorder who developed repeated suicidal ideation specifically due to the treatment with Venlafaxine. A first suicide attempt years ago occurred while being treated with Venlafaxine. Subsequent treatment with SSRIs or other antidepressants involved no suicidal ideation. Re-commencement of Venlafaxine four years later immediately led to a second suicide attempt. This unwanted effect subsided immediately after switching to another SNRI (i.e. Duloxetine. The case report underlines the importance of onset of suicide risk in panic disorders due to specific antidepressants.

    Stress constitutes a risk factor for diseases where the immune system plays a significant role. Stress is recognized as a possible trigger for flare ups during the course of multiple sclerosis (MS). The disclosure to the patient of the diagnosis of MS, the commencement of immunomodulatory therapy, and the unpredictability and vagaries of disease progression are all sources of stress. Biological stress systems such as the hypothalamic-pituitary-adrenal system and the sympathetic nervous system may influence the pathogenesis and the disease course of MS. The ability to cope with stress may also be impaired, mediated for example by cognitive deficits or loss of abilities and resources as disease progresses or by the high prevalence of concurrent mood disturbances such as depression and chronic fatigue. Psychiatric comorbidities of MS disease or therapy as well as impairments of coping strategies are underrecognized in clinical practice. Treatment plans for depression among MS patients, as the most common psychiatric comorbidity, should be individualized with integrated approaches. Antidepressants are effective for the treatment of depression in MS patients although further clinical research into the neurobiological and psychological bases of depressive disorders in MS patients is clearly needed. In therapy, coping strategies can be enhanced through multidisciplinary assessment of the various challenges and restrictions imposed by the disease and assisting and supporting the patient in addressing these. Exercise, as a form of positive stress (eustress), also has a role in therapy.

    Treatments for major depressive disorder (MDD) act at different hierarchical levels of biological complexity, ranging from the individual synapse to the brain as a whole. Theories of antidepressant medication action traditionally have focused on the level of cell-to-cell interaction and synaptic neurotransmission. However, recent evidence suggests that modulation of synchronized electrical activity in neuronal networks is a common effect of antidepressant treatments, including not only medications, but also neuromodulatory treatments such as repetitive transcranial magnetic stimulation. Synchronization of oscillatory network activity in particular frequency bands has been proposed to underlie neurodevelopmental and learning processes, and also may be important in the mechanism of action of antidepressant treatments. Here, we review current research on the relationship between neuroplasticity and oscillatory synchrony, which suggests that oscillatory synchrony may help mediate neuroplastic changes related to neurodevelopment, learning, and memory, as well as medication and neuromodulatory treatment for MDD. We hypothesize that medication and neuromodulation treatments may have related effects on the rate and pattern of neuronal firing, and that these effects underlie antidepressant efficacy. Elucidating the mechanisms through which oscillatory synchrony may be related to neuroplasticity could lead to enhanced treatment strategies for MDD.

    Several works report brain impairment of metabolism as a mechanism underlying depression. Citrate synthase and succinate dehydrogenase are enzymes localized within cells in the mitochondrial matrix and are important steps of Krebs cycle. In addition, citrate synthase has been used as a quantitative enzyme marker for the presence of intact mitochondria. Thus, we investigated citrate synthase and succinate dehydrogenase activities from rat brain after chronic administration of paroxetine, nortriptiline and venlafaxine. Adult male Wistar rats received daily injections of paroxetine (10mg/kg), nortriptiline (15mg/kg), venlafaxine (10mg/kg) or saline in 1.0mL/kg volume for 15 days. Twelve hours after the last administration, the rats were killed by decapitation, the hippocampus, striatum and prefrontal cortex were immediately removed, and activities of citrate synthase and succinate dehydrogenase were measured. We verified that chronic administration of paroxetine increased citrate synthase activity in the prefrontal cortex, hippocampus, striatum and cerebral cortex of adult rats; cerebellum was not affected. Chronic administration of nortriptiline and venlafaxine did not affect the enzyme activity in these brain areas. Succinate dehydrogenase activity was increased by chronic administration of paroxetine and nortriptiline in the prefrontal cortex, hippocampus, striatum and cerebral cortex of adult rats; cerebellum was not affected either. Chronic administration of venlafaxine increased succinate dehydrogenase activity in prefrontal cortex, but did not affect the enzyme activity in cerebellum, hippocampus, striatum and cerebral cortex. Considering that metabolism impairment is probably involved in the pathophysiology of depressive disorders, an increase in these enzymes by antidepressants may be an important mechanism of action of these drugs.

    Antidepressants have appeared to be more effective than placebo treatment in treating depressive syndromes in patients with Parkinson's disease (PD). To identify factors that predict improvement in depressive symptoms during antidepressant treatment in depressed PD patients. A secondary analysis was performed on the dataset of the Randomized Placebo-controlled Study of Antidepressants in PD (SAD-PD), in which 76 patients received active treatment with either paroxetine or venlafaxine extended release (XR), and 39 patients received placebo treatment. Backward stepwise regression analyses were conducted with change in 24-item Hamilton Depression Rating Scale (HAMD-24) score between assessments at baseline and week 12 as the main outcome measure, and sex, age, baseline HAMD-24 score, Unified Parkinson's Disease Rating Scale section III (UPDRS-III) score, Mini-Mental State Examination (MMSE), and the Clinical Anxiety Scale (CAS) as independent variables. In both the active treatment and placebo groups, higher baseline HAMD-24 score and lower UPDRS-III score were associated with greater reduction in HAMD-24 score. Higher anxiety scores predicted less response in the active treatment group. Higher MMSE scores predicted greater response only in the placebo-treated group. Sex and age were no predictors of response. Higher pre-treatment depression scores and lower pre-treatment anxiety scores are the two most important predictors for improvement during antidepressant treatment in depressed PD patients, which is in line with those found in treatment studies of depressed non-PD patients. Furthermore, our results indicate the requirement for different or more intensive treatment for depressed PD patients with more severe anxiety symptoms. Copyright © 2014 Elsevier Ltd.

    Antidepressants (ADs) are used as first-line treatment for most stress-related psychiatric disorders. The alterations in brain circuit dynamics that can arise from stress exposure and underlie therapeutic actions of ADs remain, however, poorly understood. Here, enabled by a recently developed voltage-sensitive dye imaging (VSDI) assay in mouse brain slices, we examined the impact of chronic stress and concentration-dependent effects of eight clinically used ADs (belonging to different chemical/functional classes) on evoked neuronal activity propagations through the hippocampal trisynaptic circuitry (HTC: perforant path → dentate gyrus (DG) → area CA3 → area CA1). Exposure of mice to chronic social defeat stress led to markedly weakened activity propagations ("HTC-Waves"). In contrast, at concentrations in the low micromolar range, all ADs, which were bath applied to slices, caused an amplification of HTC-Waves in CA regions (invariably in area CA1). The fast-acting "antidepressant" ketamine, the mood stabilizer lithium, and brain-derived neurotrophic factor (BDNF) exerted comparable enhancing effects, whereas the antipsychotic haloperidol and the anxiolytic diazepam attenuated HTC-Waves. Collectively, we provide direct experimental evidence that chronic stress can depress neuronal signal flow through the HTC and demonstrate shared opposing effects of ADs. Thus, our study points to a circuit-level mechanism of ADs to counteract stress-induced impairment of hippocampal network function. However, the observed effects of ADs are impossible to depend on enhanced neurogenesis.

    Full Text Available Antidepressants (ADs are used as first-line treatment for most stress-related psychiatric disorders. The alterations in brain circuit dynamics that can arise from stress exposure and underlie therapeutic actions of ADs remain, however, poorly understood. Here, enabled by a recently developed voltage-sensitive dye imaging assay in mouse brain slices, we examined the impact of chronic stress and concentration-dependent effects of eight clinically used ADs (belonging to different chemical/functional classes on evoked neuronal activity propagations through the hippocampal trisynaptic circuitry (HTC: perforant path - dentate gyrus - area CA3 - area CA1. Exposure of mice to chronic social defeat stress led to markedly weakened activity propagations (HTC-Waves. In contrast, at concentrations in the low micromolar range, all ADs, which were bath applied to slices, caused an amplification of HTC-Waves in CA regions (invariably in area CA1. The fast-acting antidepressant ketamine, the mood stabilizer lithium, and brain-derived neurotrophic factor (BDNF exerted comparable enhancing effects, whereas the antipsychotic haloperidol and the anxiolytic diazepam attenuated HTC-Waves. Collectively, we provide direct experimental evidence that chronic stress can depress neuronal signal flow through the HTC and demonstrate shared opposing effects of ADs. Thus, our study points to a circuit-level mechanism of ADs to counteract stress-induced impairment of hippocampal network function. However, the observed effects of ADs are impossible to depend on enhanced neurogenesis.

    Curcumin is the active ingredient of commonly used spice Curuma longa Linn. In the present study, the antidepressant like activity of curcumin and its combination with fluoxetine and imipramine was studied in acute model (three doses 24, 5 and 1 h before test) of forced swimming test (FST) in glass jar and tail suspension test (TST) in mice and in chronic model (14 day study) of FST with water wheel in rats. All the tests were carried out in the following seven groups (n = 6 in each group), drugs being given orally (doses for mice): Group 1 (vehicle), group 2 (curcumin 50 mg/kg), group 3 (curcumin 100 mg/kg), group 4 (fluoxetine 20 mg/kg), group 5 (imipramine 15 mg/kg), group 6 (curcumin 100 mg/kg plus fluoxetine 20 mg/kg) and group 7 (curcumin 100 mg/kg plus imipramine 15 mg/kg). Equivalent doses for rats were used. Both the acute model of FST and TST, and the chronic model of FST with water wheel showed significant antidepressant like activity of curcumin in 100 mg/kg dose as compared to vehicle control (p imipramine (p > 0.05) but its addition to fluoxetine and imipramine did not improve their antidepressant activity (p > 0.05). Curcumin increased both the swimming and climbing behavior in FST, thus its antidepressant like activity could be due to an increase in serotonin, norepinephrine and dopamine levels in the brain. Curcumin can be a useful antidepressant especially in cases which respond to drugs having mixed effects on serotonin and catecholamines levels in the brain.

    Efficacy of antidepressants fluvoxamine, amitriptyline and transcranial electrostimulation of the brain in the treatment of chronic daily headache has been studied. Amitriptyline had the highest effect in dosage 50 mg daily but was not well tolerated by patients that resulted in that only 50% of them finished the study. Fluvoxamine had high efficacy and good tolerability in the treatment of chronic daily headache and medication overuse headache. Small dosages of amitriptyline and fluvoxamine potentiated the analgesic effect of transcranial electrostimulation of the brain. The combination of antidepressants with transcranial electrostimulation of the brain alleviated the negative effect of the withdrawal of overused analgesics and may be recommended for out-patient use.

    Objective This study aimed to evaluate the total antioxidant activity (TAA) in patients with major depressive disorder (MDD) and the effect of antidepressants on TAA using a novel potentiometric method. Methods Twenty-eight patients with MDD and thirty-one healthy controls were enrolled in this study. The control group comprised 31 healthy individuals matched for gender, drinking and smoking status. We assessed symptoms of depression using the Hamilton Depression Rating Scale (HAMD) and the Beck Depression Inventory (BDI). We measured TAA using potentiometry. All measurements were made at baseline and four and eight weeks later. Results There was a significant negative correlation between BDI scores and TAA. TAA was significantly lower in the MDD group than in controls. When the MDD group was subdivided into those who showed clinical response to antidepressant therapy (response group) and those who did not (non-response group), only the non-response group showed lower TAA, while the response group showed no significant difference to controls at baseline. After eight weeks of antidepressant treatment, TAA in both the response and non-response groups was similar, and there was no significant difference among the three groups. Conclusion These results suggest that the response to antidepressant treatment in MDD patients might be predicted by measuring TAA. PMID:27081384

    Depression is a complex psychiatric disorder, and its etiology and pathophysiology are not completely understood. Depression involves changes in many biogenic amine, neuropeptide, and oxidative systems, as well as alterations in neuroendocrine function and immune-inflammatory pathways. Oleamide is a fatty amide which exhibits pharmacological effects leading to hypnosis, sedation, and anti-anxiety effects. In the present study, the chronic mild stress (CMS) model was used to investigate the antidepressant-like activity of oleamide. Rats were exposed to 10weeks of CMS or control conditions and were then subsequently treated with 2weeks of daily oleamide (5mg/kg, i.p.), fluoxetine (10mg/kg, i.p.), or vehicle. Protein extracts from the hippocampus were then collected, and hippocampal maps were generated by way of two-dimensional gel electrophoresis (2-DE). Altered proteins induced by CMS and oleamide were identified through mass spectrometry and database searches. Compared to the control group, the CMS rats exhibited significantly less body weight gain and decreased sucrose consumption. Treatment with oleamide caused a reversal of the CMS-induced deficit in sucrose consumption. In the proteomic analysis, 12 protein spots were selected and identified. CMS increased the levels of adenylate kinase isoenzyme 1 (AK1), nucleoside diphosphate kinase B (NDKB), histidine triad nucleotide-binding protein 1 (HINT1), acyl-protein thioesterase 2 (APT-2), and glutathione S-transferase A4 (GSTA4). Compared to the CMS samples, seven spots changed significantly following treatment with oleamide, including GSTA4, glutathione S-transferase A6 (GSTA6), GTP-binding nuclear protein Ran (Ran-GTP), ATP synthase subunit d, transgelin-3, small ubiquitin-related modifier 2 (SUMO2), and eukaryotic translation initiation factor 5A-1 (eIF5A1). Of these seven proteins, the level of eIF5A1 was up-regulated, whereas the remaining proteins were down-regulated. In conclusion, oleamide has antidepressant

    Full Text Available Recent studies have indicated the potential clinical use of near infrared spectroscopy (NIRS as a tool in assisting the diagnosis of major depressive disorder (MDD; however, it is still unclear whether NIRS signal changes during cognitive task are state- or trait-dependent, and whether NIRS could be a neural predictor of treatment response. Therefore, we conducted a longitudinal study to explore frontal haemodynamic changes following antidepressant treatment in medication-naïve MDD using 52-channel NIRS. This study included 25 medication-naïve individuals with MDD and 62 healthy controls (HC. We performed NIRS scans before and after antidepressant treatment and measured changes of [oxy-Hb] activation during a verbal fluency task (VFT following treatment. Individuals with MDD showed significantly decreased [oxy-Hb] values during a VFT compared with HC in the bilateral frontal and temporal cortices at baseline. There were no [oxy-Hb] changes between pre- and post-antidepressant treatment time points in the MDD cohort despite significant improvement in depressive symptoms. There was a significant association between mean [oxy-Hb] values during a VFT at baseline and improvement in depressive symptoms following treatment in the bilateral inferior frontal and middle temporal gyri in MDD. These findings suggest that hypofrontality response to a VFT may represent a potential trait marker for depression rather than a state marker. Moreover, the correlation analysis indicates that the NIRS signals before the initiation of treatment may be a biological marker to predict patient's clinical response to antidepressant treatment. The present study provides further evidence to support a potential application of NIRS for the diagnosis and treatment of depression.

  1. Acute Treatment with a Novel TRPC4/C5 Channel Inhibitor Produces Antidepressant and Anxiolytic-Like Effects in Mice.

    Full Text Available Transient receptor potential canonical (TRPC channels are widely expressed in brain and involved in various aspects of brain function. Both TRPC4 and TRPC5 have been implicated in innate fear function, which represents a key response to environmental stress. However, to what extent the TRPC4/C5 channels are involved in psychiatric disorders remains unexplored. Here, we tested the antidepressant and anxiolytic-like effects of a newly identified TRPC4/C5 inhibitor, M084. We show that a single intraperitoneal administration of M084 at 10 mg/kg body weight to C57BL/6 male mice significantly shortened the immobility time in forced swim test and tail suspension test within as short as 2 hours. The M084-treated mice spent more time exploring in illuminated and open areas in light/dark transition test and elevated plus maze test. In mice subjected to chronic unpredictable stress, M084 treatment reversed the enhanced immobility time in forced swim test and decreased the latency to feed in novelty suppressed feeding test. The treatment of M084 increased BDNF expression in both mRNA and protein levels, as well as phosphorylation levels of AKT and ERK, in prefrontal cortex. Our results indicate that M084 exerts rapid antidepressant and anxiolytic-like effects at least in part by acting on BDNF and its downstream signaling. We propose M084 as a lead compound for further druggability research.

    Excessive activation of the hypothalamic-pituitary-adrenal (HPA) axis has been associated with numerous diseases, including depression, and the tricyclic antidepressant imipramine has been shown to suppress activity of the HPA axis. Central hypothalamic control of the HPA axis is complex and involves a number of neuropeptides released from multiple hypothalamic subnuclei. The present study was therefore designed to determine the effects of imipramine administration on the mouse hypothalamus using a peptidomics approach. Among the factors found to be downregulated after acute (one day) or chronic (21 days) imipramine administration were peptides derived from secretogranin 1 (chromogranin B) as well as peptides derived from cerebellin precursors. In contrast, peptides SRIF-14 and SRIF-28 (1-11) derived from somatostatin (SRIF, somatotropin release inhibiting factor) were significantly upregulated by imipramine in the hypothalamus. Because diminished SRIF levels have long been known to occur in depression, a second part of the study investigated the roles of individual SRIF receptors in mediating potential antidepressant effects. SRA880, an antagonist of the somatostatin-1 autoreceptor (sst1) which positively modulates release of endogenous SRIF, was found to synergize with imipramine in causing antidepressant-like effects in the tail suspension test. Furthermore, chronic co-administration of SRA880 and imipramine synergistically increased BDNF mRNA expression in the cerebral cortex. Application of SRIF or L054264, an sst2 receptor agonist, but not L803807, an sst4 receptor agonist, increased phosphorylation of CaMKII and GluR1 in cerebrocortical slices. Our present experiments thus provide evidence for antidepressant-induced upregulation of SRIF in the brain, and strengthen the notion that augmented SRIF expression and signaling may counter depressive-like symptoms.

    Variant rs2522833 of the Piccolo-encoding gene PCLO has recently been found to be associated with major depressive disorder (MDD). PCLO encodes a presynaptic cytomatrix protein which influences monoamine neurotransmitter release. Piccolo could therefore play an important role in treatment response to antidepressant therapy and the improvement of alterations in HPA system reactivity. We investigated the influence of the coding variant rs2522833 in the PCLO gene on treatment response in 205 in-patients with unipolar depression. Treatment response was measured (1) at the level of psychopathology using the Hamilton Depression Rating Scale (HAMD) and (2) with the combined dexamethasone/corticotropin-releasing hormone (Dex/CRH) test, which is a refined tool for showing dysregulation of the hypothalamic-pituitary-adrenocortical (HPA) system, a neurobiological finding in depression. While we did not find an association between variation in PCLO and HAMD scores, HPA dysregulation was less pronounced in carriers of the AA genotype than in carriers of one or two C alleles. HPA activity of individuals with the AA genotype only marginally changed during 4-wk antidepressant treatment, whereas C allele carriers showed a higher hormonal secretion at admission than carriers of the AA genotype but lower responsivity to the Dex/CRH challenge after 4 wk. Our results point to a moderating role of PCLO SNP rs2522833 on HPA regulation during antidepressant treatment, which may represent a neurobiological feature of stability of clinical response.

    Major depression is a common mental health problem and associated with significant morbidity and mortality, including impaired social and physical functioning and increased risk for suicide. Electroconvulsive therapy (ECT) is highly efficacious in treatment-resistant depressive disorders, but cognitive side effects are frequently associated with the treatment. Magnetic seizure therapy (MST) is a form of convulsive therapy, using magnetic fields in order to induce therapeutic seizures. First studies suggested that cognitive side effects of MST, including postictal recovery time, are more benign than those resulting from ECT treatment. In this open-label study we tested the hypothesis that MST is associated with clinically significant antidepressant effects in treatment-resistant depression (TRD) as an add-on therapy to a controlled pharmacotherapy. Twenty patients suffering from TRD were randomly assigned to receive either MST or ECT starting from July 2006 until November 2008. Primary outcome measure was antidepressant response assessed by Montgomery Åsberg Depression Scale. Secondary outcome measures included Hamilton Depression Rating Scale, Hamilton Anxiety Scale, Beck Depression Inventory and 90-Item Symptom Checklist. Antidepressant response (improvement of 50% in MADRS ratings) was statistically significant and of similar size in both treatment groups. Cognitive side effects were observed in neither group. Characteristics in MST- and ECT-induced seizures were comparable, especially regarding ictal activity and postictal suppression. Thus, MST may be a potential alternative to ECT if efficacy and safety are validated in larger clinical trials.

    Most patients with chronic pain receive multimodal treatment. There is scant literature to guide us, but when approaching combination pharmacotherapy, the practitioner and patient must weigh the benefits with the side effects; many medications have modest effect yet carry significant side effects that can be additive. Chronic pain often leads to depression, anxiety, and deconditioning, which are targets for treatment. Structured interdisciplinary programs are beneficial but costly. Interventions have their place in the treatment of chronic pain and should be a part of a multidisciplinary treatment plan. Further research is needed to validate many common combination treatments.

    Anxiety disorders represent one of the most prevalent forms of psychopathology among children and adolescents. As these problems tend to persist and have a negative impact on young people's development, there is a need for evidence-based interventions. Cognitive-behavioral therapy (CBT) is at present the treatment of first choice, but pharmacotherapy and in particular antidepressant medication may be a viable alternative or adjunct to CBT. This paper provides a detailed overview of controlled treatment outcome studies on the efficacy of tricyclic antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs) and serotonin-noradrenaline reuptake inhibitors (SNRIs) in children and adolescents with anxiety disorders. Further, a discussion is provided on how clinically anxious youths should be preferably treated, with special focus on the position of pharmacotherapy in the treatment process. The short-term efficacy of antidepressants in anxious youths is good, and this is particularly true for SSRIs. Therefore, this type of medication should be viewed as a viable treatment option, in particular for youths with obsessive-compulsive disorder (OCD) or other severe and pervasive anxiety disorders. More research is needed on the long-term effects, the consequences of prolonged use of this type of medication for children's developing brains and the efficacy of an intervention in which CBT and SSRIs are combined.

    The prevalence, characteristics and implications of excessive arousal-activation in children and adolescents treated with antidepressants for specific illnesses have not been systematically examined. We compared reports of antidepressant trials (n = 6,767 subjects) in juvenile depressive (n = 17) and anxiety disorders (n = 25) for consensus-based indications of psychopathological mood elevation or behavioral activation. Rates of excessive arousal-activation during treatment with antidepressants were at least as high in juvenile anxiety (13.8%) as depressive (9.79%) disorders, and much lower with placebos (5.22 vs. 1.10%, respectively; both p antidepressant/placebo risk ratio for such reactions in paired comparisons was 3.50 (12.9/3.69%), and the meta-analytically pooled rate ratio was 1.7 (95% confidence interval: 1.2-2.2; both p ≤ 0.001). Overall rates for 'mania or hypomania', specifically, were 8.19% with and 0.17% without antidepressant treatment, with large drug/placebo risk ratios among depressive (10.4/0.45%) and anxiety (1.98/0.00%) disorder patients. Risks of excessive mood elevation during antidepressant treatment, including mania-hypomania, were much greater than with placebo, and similar in juvenile anxiety and depressive disorders. Excessive arousal-activation in children or adolescents treated with antidepressants for anxiety as well as depressive disorders calls for particular caution and monitoring for potential risk of future bipolar disorder.

    Recent studies have shown overall accuracy rates of 72% and 88% using baseline and/or 1-week change in QEEG biomarkers to predict clinical outcome to treatment with various antidepressant medications. In some cases, findings have been replicated across academic institutions and have been studied in the context of randomized, placebo-controlled trials. Recent EEG findings are corroborated by studies that use techniques with greater spatial resolution (eg, PET, MEG) in localizing brain regions pertinent to clinical response. As such, EEG measurements increasingly are validated by other physiologic measurements that have the ability to assess deeper brain structures. Continued progress along these lines may lead to the realized promise of QEEG biomarkers as predictors of antidepressant treatment outcome in routine clinical practice. In the larger context, use of QEEG technology to predict antidepressant response in major depression may mean that more patients will achieve response and remission with less of the trial-and-error approach that currently accompanies antidepressant treatment.

    Despite the high prevalence of depression in people with neurological disorders, no previous study has sought to summarise existing evidence on the use of antidepressants in this population. A systematic review and meta-analysis was undertaken to determine whether antidepressants are more effective than placebo in the treatment of depression in neurological disorders, and whether any benefit is associated with improvement in function. Embase, Pubmed, Psycinfo and Cochrane trial registers were searched for randomised controlled trials (RCTs) comparing the efficacy of antidepressant and placebo in the treatment of depression in adults with a neurological disorder. 20 RCTs were included in the review, including patients with Parkinson's disease, multiple sclerosis, brain injury, epilepsy and stroke. Outcomes were analysed at four time points: 4-5 weeks, 6-8 weeks, 9-18 weeks and >18 weeks. The primary outcome was response to treatment at 6-8 weeks. The evidence favoured the use of antidepressants over placebo at all time points although pooled results were not statistically significant at all time points. At 6-8 weeks, antidepressant treatment was associated with a greater than twofold odds of remission (OR 2.23; 95% CI 1.54 to 3.23; number needed to treat=7). Fewer data were available for quality of life, and functional and cognitive outcomes, and there was little evidence of improvement with antidepressant treatment. Antidepressants are effective for the treatment of depression in patients with neurological disorders but the evidence for the efficacy of antidepressants in improving quality of life, and functional and cognitive outcomes is inconclusive.

    The relationship between antidepressants and monoamine concentrations in the brain has been well investigated, but few studies have investigated the relationship between antidepressants and amino acid concentrations in the brain. The purpose of the present study was therefore to investigate the effect of the chronic antidepressant imipramine on amino acid and monoamine concentrations in the mouse brain and plasma. Chronic imipramine treatment decreased the concentration of 5-hydroxyindoleaceticacid/5-hydroxytryptamine in the cerebral cortex and increased that of norepinephrine (NE) in the hippocampus. Since these changes were conspicuous effects of the antidepressant, we concluded that imipramine acts on the central nervous system. No change in amino acid concentrations in plasma was induced by chronic imipramine treatment, but several changes were confirmed in the cerebral cortex, the hypothalamus and the hippocampus. Chronic imipramine treatment caused increases in L-methionine, L-tyrosine, and L-lysine in the cerebral cortex, and an increase in L-aspartate in the hypothalamus. Contrary to this, the concentrations of L-aspartate, L-serine, L-asparagine, glycine, L-glutamine, gamma-aminobutyric acid, L-threonine, L-arginine, L-proline, L-valine, and L-methionine in the hippocampus were decreased by chronic imipramine treatment. The present results demonstrate that the metabolism of several amino acids in the brain, but not of those in plasma, was altered by chronic imipramine treatment. The findings in the present study may help to further elucidate the relationship between amino acids and the effects and side effects of antidepressants.

    Chronic mild stress (CMS) procedure was used to study an antidepressant-like activity of AGN 2979, a selective inhibitor of tryptophan hydroxylase (TH) activation. At the dose of 4 mg/kg, AGN 2979 fully reversed the CMS-induced reduction in the consumption of 1% sucrose solution. This effect was maintained for at least 1 week after cessation of treatment and no signs of withdrawal were observed in either stressed or control animals receiving AGN 2979. The lower (1 mg/kg) and higher (16 mg/kg) doses were ineffective. The magnitude of action of AGN 2979 in the CMS model was comparable to that of imipramine (10 mg/kg) but its onset of action appears to be faster since the inhibition of sucrose intake in stressed animals was already reversed after the 1st week of AGN 2979 administration while imipramine required 3 weeks of treatment to cause similar effect. These results provide support for the hypothesis that inhibition of TH activation may result in a potent antidepressant activity.

    Depression is one of the most common mental disorders and a primary cause of disability. To better treat patients suffering this illness, elucidation of the underlying psychopathological and neurobiological mechanisms is urgently needed. Based on the above-mentioned evidence, we sought to investigate the effects of neuropeptide Y (NPY) treatment in tricyclic antidepressant treatment-resistant depression induced by adrenocorticotropic hormone (ACTH) administration. Mice were treated with NPY (5.84, 11.7 or 23.4mmol/μl) intracerebroventricularly (i.c.v.) for one or five days. The levels of serum corticosterone, tryptophan (TRP), kynurenine (KYN), serotonin (5-HT), 5-hydroxyindoleacetic acid (5-HIAA), brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF) and indoleamine 2,3-dioxygenase (IDO) activity in the hippocampus were analyzed. The behavioral parameters (depressive-like and locomotor activity) were also verified. This study demonstrated that ACTH administration increased serum corticosterone levels, KYN, 5-HIAA levels, IDO activity (hippocampus), immobility in the forced swimming test (FST) and the latency to feed in the novelty suppressed feeding test (NSFT). In addition, ACTH administration decreased the BDNF and NGF levels in the hippocampus of mice. NPY treatment was effective in preventing these hormonal, neurochemical and behavioral alterations. It is suggested that the main target of NPY is the modulation of corticosterone and neuronal plasticity protein levels, which may be closely linked with pharmacological action in a model of tricyclic antidepressant treatment-resistant depression. Thus, this study demonstrated a protective effect of NPY on the alterations induced by ACTH administration in mice, indicating that it could be useful as a therapy for the treatment of tricyclic antidepressant treatment-resistant depression.

  19. Antidepressants and dementia

    DEFF Research Database (Denmark)

    2009-01-01

    BACKGROUND: It has been suggested that antidepressants may have neuroprotective abilities but it has newer been investigated lately whether treatment with antidepressants reduces the risk of dementia. METHOD: Linkage of registers of all prescribed antidepressants and diagnoses of dementia...... in Denmark during a period from 1995 to 2005. RESULTS: Persons who purchased antidepressants once (N=687,552) had an increased rate of dementia compared to persons unexposed to antidepressants (N=779,831). Nevertheless, the rate of dementia changed over time; thus during the initial prescription periods...... the rate increased with the number of prescriptions but continued long-term antidepressants treatment was associated with a reduction in the rate of dementia, however, not to the same level as the rate for the general population. This pattern was found for all classes of antidepressants (SSRIs, newer non...

    Current gold standard in the treatment of depression includes pharmacotherapeutic and psychotherapeutic strategies together with social support. Due to the actually discussed controversies concerning the differential efficacy of antidepressants, a contribution to a comprehensive clarification seems to be necessary to avert further deterioration and uncertainty from patients, relatives, and their treating psychiatrists and general practitioners. Both efficacy and clinical effectiveness of antidepressants in the treatment of depressive disorders can be confirmed. Clinically meaningful antidepressant treatment effects were confirmed in different types of studies. Methodological issues of randomized controlled studies, meta-analyses, and effectiveness studies will be discussed. Furthermore, actual data about the differential efficacy and effectiveness of antidepressants with distinct pharmacodynamic properties and about outcome differences in studies using antidepressants and/or psychotherapy are discussed. This is followed by a clinically oriented depiction-the differential clinical effectiveness of different pharmacodynamic modes of action of antidepressants in different subtypes of depressive disorders. It can be summarized that the spectrum of different antidepressant treatments has broadened during the last decades. The efficacy and clinical effectiveness of antidepressants is statistically significant and clinically relevant and proven repeatedly. For further optimizing antidepressant treatment plans, clearly structured treatment algorithms and the implementation of psychotherapy seem to be useful. A modern individualized antidepressant treatment in most cases is a well-tolerated and efficacious tool to minimize the negative impact of the otherwise devastating and life-threatening outcome of depressive disorders.

    Accumulating evidence regarding clinical, neurobiological, genetic, and environmental factors suggests a bidirectional link between obesity and depressive disorders. Although a few studies have investigated the link between obesity/excess body weight and the response to antidepressants in depressive disorders, the effect of weight on treatment response remains poorly understood. In this review, we summarized recent data regarding the relationship between the response to antidepressants and obesity/excess body weight in clinical studies of patients with depressive disorders. Although several studies indicated an association between obesity/excess body weight and poor antidepressant responses, it is difficult to draw definitive conclusions due to the variability of subject composition and methodological differences among studies. Especially, differences in sex, age and menopausal status, depressive symptom subtypes, and antidepressants administered may have caused inconsistencies in the results among studies. The relationship between obesity/excess body weight and antidepressant responses should be investigated further in high-powered studies addressing the differential effects on subject characteristics and treatment. Moreover, future research should focus on the roles of mediating factors, such as inflammatory markers and neurocognitive performance, which may alter the antidepressant treatment outcome in patients with comorbid obesity and depressive disorder.

    Full Text Available Gillian W Reierson, Claudio A Mastronardi, Julio Licinio, Ma-Li WongCenter on Pharmacogenomics, Department of Psychiatry and Behavioral Sciences, University of Miami Miller School of Medicine, Miami, FL, USAAbstract: Circadian rhythm disturbances can occur as part of the clinical symptoms of major depressive disorder and have been found to resolve with antidepressant therapy. The pineal gland is relevant to circadian rhythms as it secretes the hormone melatonin following activation of the cyclic adenosine monophosphate (cAMP signaling cascade and of arylalkylamine N-acetyltransferase (AA-NAT, the rate-limiting enzyme for its synthesis. Cyclic AMP is synthesized by adenylate cyclases (AC and degraded by phosphodiesterases (PDEs. Little is known about the contribution of the PDE system to antidepressant-induced alterations in pineal cAMP signaling and melatonin synthesis. In the present study we used enzyme immunoassay to measure plasma melatonin levels and pineal cAMP levels and as well as quantitative real-time polymerase chain reaction to measure pineal expression of PDE, AC, and AA-NAT genes in rats chronically treated with the prototypic antidepressant fluoxetine. We found elevated melatonin synthesis with increased pineal AA-NAT gene expression and daytime plasma melatonin levels and downregulated cAMP signaling with increased PDE and unchanged AC pineal gene expression, and decreased content of pineal cAMP. We conclude that chronic fluoxetine treatment increases daytime plasma melatonin and pineal AA-NAT gene expression despite downregulated pineal cAMP signaling in the rodent.Keywords: antidepressant, melatonin, pineal, nucleotides, cyclic, phosphodiesterase, rat

  3. 1H-NMR-based metabonomic studies on the anti-depressant effect of genipin in the chronic unpredictable mild stress rat model.

    Full Text Available The purpose of this work was to investigate the anti-depressant effect of genipin and its mechanisms using (1H-NMR spectroscopy and multivariate data analysis on a chronic unpredictable mild stress (CUMS rat model. Rat serum and urine were analyzed by nuclear magnetic resonance (NMR-based metabonomics after oral administration of either genipin or saline for 2 weeks. Significant differences in the metabolic profile of the CUMS-treated group and the control group were observed, which were consistent with the results of behavioral tests. Metabolic effects of CUMS included decreases in serum trimetlylamine oxide (TMAO and β-hydroxybutyric acid (β-HB, and increases in lipid, lactate, alanine and N-acetyl-glycoproteins. In urine, decreases in creatinine and betaine were observed, while citrate, trimethylamine (TMA and dimethylamine were increased. These changes suggest that depression may be associated with gut microbes, energy metabolism and glycometabolism. Genipin showed the best anti-depressive effects at a dose of 100 mg/kg in rats. These results indicate that metabonomic approaches could be powerful tools for the investigation of the biochemical changes in pathological conditions or drug treatment.

    Xiao-Chai-Hu-Tang (XCHT) has been proven to be effective for the clinical treatment of depression. However, the mechanisms of definite antidepressant-like effects and detailed metabolic biomarkers were still unclear in this prior study. Here, we have investigated the metabolic profiles and potential biomarkers in a chronic unpredictable mild stress model after treatment with XCHT. Metabonomics based on ultra-high performance liquid chromatography coupled with mass spectrometry was used to profile the metabolic fingerprints of serum obtained from a rat model with chronic unpredictable mild stress with and without XCHT treatment. The model rats showed a significant decrease in sucrose preference and food consumption, and these depression-like symptoms were significantly improved by XCHT. Through principal component analysis (PCA), nine potential biomarkers of tryptophan, uric acid, phenylalanine, cholic acid and lysophosphatidylcholine (C18:0 LPC, C16:0 LPC, C16:1 LPC, C18:1 LPC, C20:4 LPC) were characterized as potential biomarkers involved the pathogenesis of depression. The therapeutic effect of XCHT on depression may involve in amino acid metabolism, lipid metabolism, oxidative stress and inflammation response. The present investigation highlights that metabonomics is a valuable tool for studying the essence of depression as well as evaluating the efficacy of the corresponding drug treatment.

    Increasing clinical evidence for the effectiveness of herbal antidepressants has led to investigations at the molecular level. Using two-dimensional gel electrophoresis, this study investigated similarities in protein expression between clomipramine, St John's wort and a Chinese herbal formula, xiao-yao-san, often used in mood disorder treatment. HT22 cells, derived from a mouse hippocampal cell line, were treated for 24 h, and protein expression was compared with that of the untreated cells (n = 4/group). Forty-three protein spots were found to be significantly differentially expressed (P < 0.05) in more than one of the treatment groups. Twenty-nine of these were identified using mass spectrometry. The most affected proteins were those involved in the cytoskeleton and energy metabolism, and an up-regulation of vimentin by all three treatments was confirmed by Western blotting. This study provides preliminary evidence for multiple common molecular targets between conventional and alternative antidepressants, which appear to collectively affect neuronal plasticity.

    Background Due to the quick rhythm of life and work pressure, more and more people suffer from sleep quality problems. In this study, we investigated the effect of electroacupuncture on sleep quality of chronic insomniacs and the safety of electroacupuncture therapy.Methods Four courses of electroacupuncture treatment were applied to 47 patients. With pre-treatment and post-treatment self-control statistical method, Pittsburgh sleep quality index (PSQI) scores were used for evaluating sleep quality. Polysomnogram was used for detecting insomniacs' changes in sleep architecture. The safety of electroacupuncture was evaluated by monitoring the self-designed adverse events and side effects during treatment and post-treatment.Results Electroacupuncture considerably improved insomniacs' sleep quality and social function during the daytime.Electroacupuncture had certain repairing effect on the disruption in sleep architecture. At the same time,electroacupuncture prolonged slow wave sleep (SWS) time and relatively rapid eye movement sleep (REM sleep) time.There was no hangover, addiction or decrements in vigilance during the daytime (incidence rate was 0). However,insomnia rebound rate was about 23% within one month.Conclusions These results suggest that electroacupuncture has beneficial effect on sleep quality improvement in the patients with chronic insomnia, which may be associated with repairing sleep architecture, reconstructing sleep continuity,as well as prolonging SWS time and REM sleep time. Electroacupuncture treatment for chronic insomnia is safe.Therefore, electroacupuncture therapy could be a promising avenue of treatment for chronic insomnia.

    To evaluate the effectiveness of pregabalin in patients with resistant generalized anxiety disorder (GAD) and severe depressive symptoms, we carried out a post-hoc analysis of a multicenter, prospective, and observational 6-month study. We included patients who were at least 18 years old, fulfilled the Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV) criteria for GAD, showed inadequate responses to previous courses of antidepressant treatment, had Montgomery-Asberg Rating Scale scores of at least 35, had not received pregabalin previously, and were prescribed pregabalin upon entry into this study. We included 1815 patients fulfilling the DSM-IV criteria for GAD, and 133 (7.3%) fulfilled the selection criteria for these analyses. Ninety-seven percent of the patients received pregabalin (mean dose: 222 mg/day) in combination with other psychotropics. The Hamilton Anxiety Scale total score was reduced by a mean of 20.3 points (95% confidence interval, 22.1-18.4) (57.2% reduction) at month 6. Pregabalin also ameliorated comorbid depressive symptoms, with a reduction in the mean score of the Montgomery-Asberg Rating Scale of 22.3 points (95% confidence interval, 24.2-20.4) (56.6% reduction). Our results suggest that pregabalin, as part of a combination regimen with antidepressants and/or benzodiazepines, might be effective for the treatment of patients with GAD who have shown inadequate response to previous antidepressants and have severe depressive symptoms.

    In the debate on euthanasia and physician-assisted suicide, we have to exclude terminally ill patients in whom the desire for death is caused by major depression. However, it is still not clear to what degree major depression can be treated by psychiatric intervention in this setting. We evaluated the effect of antidepressant treatment in terminally ill cancer patients. Six cancer patients with suicidal ideas thought to be due to major depression were treated with tricyclic antidepressants. Three had requested terminal sedation to relieve them from their suffering. The median survival of five of these patients was 4 weeks after diagnosis; one was lost to follow-up. The efficacy of the antidepressant treatment was assessed using the Hamilton Rating Scale for Depression (HRSD). One week after the start of treatment with antidepressants, five of the six patients showed a marked improvement in their mood and showed no further suicidal thoughts or requests for terminal sedation. The average reduction in the HRSD score was 23.4 points (14-38; SD = 9. 9). Antidepressant treatment can be effective in alleviating the desire for death due to major depression, even in terminally ill cancer patients.

    Beliefs about the controllability of a disorder may be relevant in the causation, maintenance and treatment of disorders. We investigated whether congruence between patients' beliefs about controllability of a panic disorder and the type of treatment provided predicted outcome. The differential effectiveness of cognitive therapy and antidepressant treatment (paroxetine or clomipramine) was investigated in a sample of 129 panic disorder patients in a 12-week, pretest posttest placebo-controlled study. Panic frequency, agoraphobic avoidance, anxiety, depression, and disability were measured with various validated interviewer and self-report measures. Beliefs about controllability were measured with the Multidimensional Anxiety Locus of Control Scale measuring an internal, chance, therapist and medication locus of control. In order to analyze aptitude-treatment interactions a new strategy called the Regression Trunk Approach was used in addition to classical hierarchical multiple regression analysis. Using the Regression Trunk Approach we found that locus of control orientation (LOC) predicted the differential effectiveness of cognitive therapy. Those patients with a medium internal LOC who received cognitive therapy performed significantly better than all patients who received a placebo pill on 8 of the 10 outcome variables. We did not find a differential LOC effect for antidepressant treatment. No evidence for aptitude-treatment interactions using hierarchical multiple regression analysis was found. Moderately strong beliefs about self-control of panic disorder congruent with the cognitive intervention provided seem to moderate treatment effectiveness. Future studies must be more attentive to the nonlinear effects of patient characteristics on the outcome of different types of treatments. Copyright 2007 S. Karger AG, Basel.

    Our recent study demonstrates that adiponectin signaling plays a significant role in mediating physical exercise-exerted effects on hippocampal neurogenesis and antidepression in mice. Whether the findings can be translated to humans remains unknown. This study aimed to investigate the effects of Baduanjin Qigong exercise on adiponectin and to evaluate whether adiponectin is involved in the antidepressive effects of Qigong exercise on chronic fatigue syndrome (CFS)-like illness. This is a randomized, waitlist-controlled trial. One hundred eight female participants were randomly assigned to either Qigong exercise or waitlist groups. Sixteen 1.5-h Qigong lessons were conducted. Outcome measures were taken at three time points. Baseline adiponectin levels were negatively associated with body weight, body mass index, waist circumference, hip circumference, and waist/hip ratio in women with CFS-like illness. Compared with the waitlist control, Qigong exercise significantly reduced anxiety and depression symptoms and significantly raised plasma adiponectin levels (median = 0.8 vs. -0.1, p Qigong exercise were associated with decreases in depression scores for the Qigong group (r = -0.38, p = 0.04). Moreover, adjusted linear regression analysis further identified Qigong exercise and change in adiponectin levels as the significant factors accounting for reduction of depression symptoms. Baduanjin Qigong significantly increased adiponectin levels in females with CFS-like illness. Decreases in depression symptoms were associated with increases in adiponectin levels following Qigong exercise, indicating that the potential contribution of adiponectin to Qigong exercise elicited antidepressive effects in human subjects.

    The objective of this naturalistic, longitudinal treatment outcome study was to determine relapse rates in geriatric depression following treatment with antidepressants and electroconvulsive therapy in a medical-psychiatric population. Thirty-nine elderly patients (average age 71 years) with unipolar major depression were treated with either antidepressants (AD) or, if resistant to AD treatment, ECT followed by maintenance antidepressants. Patients were monitored over 18 months, and relapse rates were closely determined using the Longitudinal Interval Follow-up Evaluation (LIFE) and the 21-item Hamilton Depression Rating Scale. Although 90% of patients recovered from their index episode of depression, relapse rates were approximately 29%. These results indicate that in spite of high chances of recovery from geriatric depression, intensive psychopharmacologic and psychotherapeutic strategies are needed to decrease relapse rates in geriatric depression.

    Explanatory theories of depression have advanced in recent decades from the monoaminergic hypothesis to neurogenesis alterations to the neurohormonal hypothesis that includes the dysfunction of the inflammatory response. Currently there is a growing interest in the development of biomarkers that can contribute to diagnosis and proper treatment. To describe the role of neurotrophins such as brain-derived neurotrophic factor (BDNF) and cytokines in the pathophysiology of depressive disorder in addition to reviewing and analyzing evidence about their clinical application as biomarkers of antidepressant therapy. Relevant data research in several databases. In recent years evidence of alterations in neurogenesis mediated by the expression of BDNF in the hippocampus in the pathophysiology of depression has increased and there is ample evidence that BDNF is a marker of the diagnosis of depressive disorder and also of treatment effectiveness. There is little information about other neurotrophins. There has also been increased interest in relation to depression as an "inflammatory disease" and the link with cytokines in its pathogenesis. Evidence has been found for the usefulness of some cytokines especially IL-1 (interleukin 1), IL-6 (interleukin 6), and TNF (tumor necrosis factor) as biomarkers of antidepressant drug response in humans.

    In order to examine relationships between depression treatments (antidepressant and/or psychotherapy utilization) and adherence to antiretroviral therapy (ART), we conducted a retrospective analysis of medical and pharmacy insurance claims for privately insured persons living with HIV/AIDS (PLWHA) diagnosed with depression (n = 1,150). Participants were enrolled in 80 insurance plans from all 50 states. Adherence was suboptimal. Depression treatment initiators were significantly more likely to be adherent to ART than the untreated. We did not observe an association between psychotherapy utilization and ART adherence, yet given the limitations of the data (e.g., there is no information on types of psychological treatment and its targets), the lack of association should not be interpreted as lack of efficacy.

    Levels of brain-derived neurotrophic factor (BDNF) are reduced in the brain and serum of depressed patients and at least the reduction in serum levels is reversible upon successful treatment. These data, together with a wealth of reports using different animal models with depression-like behavior or manipulation of expression of BDNF or its receptor TrkB have implicated BDNF in the pathophysiology of depression as well as in the mechanism of action of antidepressant treatments. Recent findings have shown that posttranslational processing of BDNF gene product can yield different molecular entities that differently influence signaling through BNDF receptor TrkB and the pan-neurotrophin receptor p75(NTR). We will here review these data and discuss new insights into the possible pathophysiological roles of those new BDNF subtypes as well as recent findings on the role of BDNF mediated neuronal plasticity in mood disorders and their treatments.

Uncovering the genetic basis of the model may unravel the mechanism of antidepressant treatment. METHODS: FVB/NJ (FVB and C57BL/6J (B6 were first identified as the response and non-response strains to fluoxetine (a serotonin-specific reuptake inhibitor antidepressant treatment in the mouse FST. Simple-interval (SIM and composite-interval (CIM mappings were applied to map the quantitative trait loci (QTLs of the anti-immobility effect of fluoxetine in FST (FST(FLX in 865 male B6×FVB-F2 mice. The brain mRNA expressions of the gene with the maximum QTL-linkage signal for FST(FLX after the FST were compared between B6 and FVB mice and also compared between fluoxetine and saline treatment. The association of the variants in the human homologue of the mouse FST(FLX-QTL gene with major depressive disorder (MDD and antidepressant response were investigated in 1080 human subjects (MDD/control = 582/498. RESULTS: One linkage signal for FST(FLX-QTL was detected at an intronic SNP (rs6215396 of the mouse Zfp326 gene (maximal CIM-LOD = 9.36. The Zfp326 mRNA expression in the FVB thalamus was significantly down-regulated by fluoxetine in the FST, and the higher FVB-to-B6 Zfp326 mRNA expressions in the frontal cortex, striatum and hypothalamus diminished after fluoxetine treatment. Two coding-synonymous SNPs (rs2816881 and rs10922744 in the human homologue of Zfp326, ZNF326, were significantly associated with the 8-week antidepressant treatment response in the MDD patients (Bonferroni-corrected p = 0.004-0.028. CONCLUSIONS: The findings suggest the involvement of the Zfp326 and ZNF326 genes in antidepressant treatment response.

    Depressive and anxiety disorders are common in youth who are at risk for bipolar disorder (i.e., youth who have at least one parent with bipolar disorder) and antidepressants are commonly prescribed as treatment. However, there are few data regarding the safety and tolerability of antidepressants in this population. Therefore, we sought to prospectively examine the effects of these medications in children and adolescents who are diagnosed with depressive or anxiety disorders and have a parent with bipolar I disorder. Youth aged 9-20 years, with at least one parent with bipolar I disorder [high risk (HR)], were recruited (n = 118) and assessed using semi-structured diagnostic interviews. Participants were prospectively evaluated using a modified version of the Longitudinal Interval Follow-up Evaluation to assess changes in affective and anxiety symptoms and were treated naturalistically. Over the course of 43-227 weeks (mean duration of follow-up: 106 ± 55 weeks), 21% (n = 25) of youth had antidepressant exposure and, of these, 57% (n = 12) had an adverse reaction (e.g., irritability, aggression, impulsivity, or hyperactivity) that led to antidepressant discontinuation. Those patients who experienced an adverse reaction were significantly younger than those who did not (p = 0.02) and discontinuation of antidepressant therapy secondary to an adverse event occurred at an average of 16.7 ± 17.4 weeks (median: 11 weeks, range: 2-57 weeks). Cox proportional hazard analyses yielded a hazard ratio of 0.725 (p = 0.03), suggesting that there is a 27% decrease in the likelihood of an antidepressant-related adverse event leading to discontinuation with each one-year increase in age. Antidepressant medications may be poorly tolerated in youth with a familial risk for developing mania. Controlled studies further assessing treatments for depression and anxiety in HR youth are urgently needed. © 2013 John Wiley & Sons A/S Published by John Wiley & Sons Ltd.

    Neurosurgical treatment of pain used two kind of techniques: 1) Lesional techniques interrupt the transmission of nociceptive neural input by lesionning the nociceptive pathways (drezotomy, cordotomy, tractotomy…). They are indicated to treat morphine-resistant cancer pain and few cases of selected neuropathic pain. 2) Neuromodulation techniques try to decrease pain by reinforcing inhibitory and/or to limit activatory mechanisms. Chronic electrical stimulation of the nervous system (peripheral nerve stimulation, spinal cord stimulation, motor cortex stimulation…) is used to treat chronic neuropathic pain. Intrathecal infusion of analgesics (morphine, ziconotide…), using implantable pumps, allows to increase their efficacy and to reduce their side effects. These techniques can improve, sometimes dramatically, selected patients with severe and chronic pain, refractory to all other treatments. The quality of the analgesic outcome depends on the relevance of the indications.

    Ketamine and lithium both inhibit glycogen synthase kinase 3. In addition, lithium and ketamine have synergistic antidepressant-like effects at individually subeffective doses in rodents. We hypothesized that ketamine's antidepressant effects would be improved by therapeutic doses of lithium versus valproate and that serum lithium levels would positively correlate with ketamine's antidepressant efficacy. Thirty-six patients with treatment-resistant bipolar depression maintained on therapeutic-dose lithium (n = 23, 0.79 ± 0.15 mEq/L) or valproate (n = 13, 79.6 ± 12.4 mg/mL) received 0.5 mg/kg ketamine infusion in a randomized, double-blind, placebo-controlled, crossover trial. The primary depression outcome measure-the Montgomery-Åsberg Depression Rating Scale (MADRS)-was assessed before infusion and at numerous postinfusion time points. Both lithium (F 1,118 = 152.08, p lithium and valproate levels did not correlate with ketamine's antidepressant efficacy. Although the study was potentially underpowered, our results suggest that lithium may not potentiate ketamine's antidepressant efficacy in treatment-resistant bipolar depression.

    Full Text Available CONTEXT: Most double-blind studies of efficacy and tolerability of sertraline as compared to tricyclics in the treatment of late-life major depression have used amitriptyline as a standard, leading to the inevitable conclusion that the former drug is better tolerated than the latter, with both being equally efficacious. OBJECTIVE: To compare the antidepressant efficacy and tolerability of sertraline (50 mg/day and imipramine (150 mg/day in the first 6 weeks of the treatment of major depression in the elderly. DESIGN: A randomized double-blind parallel study with 6 weeks of follow-up. SETTING: The psychogeriatric clinic at the Institute of Psychiatry, Hospital das Clínicas, Faculty of Medicine of the University of São Paulo. PARTICIPANTS: 55 severe and moderately depressed non-demented outpatients aged 60 years or more. INTERVENTION: Patients were assigned to sertraline 50 mg/day or imipramine 150 mg/day. MAIN MEASUREMENTS: CAMDEX interview. Psychiatric diagnosis followed the guidelines for "Major Depressive Episode" according to DSM-IV criteria. Severity of symptoms was evaluated using the "CGI" and "MADRS" scales. Cognitive state was assessed using the Mini-Mental State Examination. Side effects were assessed using the "Safetee-Up" schedule. RESULTS: Both groups had a significant decrease in depressive symptoms according to the MADRS scores after 6 weeks of treatment (P = 0.01. No significant differences between groups were detected regarding treatment outcome (t = 0.4; P = 0.7. Although the dropout rate was greater in the imipramine group, the overall tolerability among patients who completed the 6-week trial was similar in both test groups. CONCLUSIONS: Both sertraline and imipramine exhibited good efficacy and an acceptable side-effect profile for elderly depressed patients after 6 weeks of antidepressant treatment.

    Previous studies have found that few chronically depressed patients remit with antidepressant medications alone. To determine the role of adjunctive psychotherapy in the treatment of chronically depressed patients with less than complete response to an initial medication trial. This trial compared 12 weeks of (1) continued pharmacotherapy and augmentation with cognitive behavioral analysis system of psychotherapy (CBASP), (2) continued pharmacotherapy and augmentation with brief supportive psychotherapy (BSP), and (3) continued optimized pharmacotherapy (MEDS) alone. We hypothesized that adding CBASP would produce higher rates of response and remission than adding BSP or continuing MEDS alone. Eight academic sites. Chronically depressed patients with a current DSM-IV-defined major depressive episode and persistent depressive symptoms for more than 2 years. Phase 1 consisted of open-label, algorithm-guided treatment for 12 weeks based on a history of antidepressant response. Patients not achieving remission received next-step pharmacotherapy options with or without adjunctive psychotherapy (phase 2). Individuals undergoing psychotherapy were randomized to receive either CBASP or BSP stratified by phase 1 response, ie, as nonresponders (NRs) or partial responders (PRs). Proportions of remitters, PRs, and NRs and change on Hamilton Scale for Depression (HAM-D) scores. In all, 808 participants entered phase 1, of which 491 were classified as NRs or PRs and entered phase 2 (200 received CBASP and MEDS, 195 received BSP and MEDS, and 96 received MEDS only). Mean HAM-D scores dropped from 25.9 to 17.7 in NRs and from 15.2 to 9.9 in PRs. No statistically significant differences emerged among the 3 treatment groups in the proportions of phase 2 remission (15.0%), partial response (22.5%), and nonresponse (62.5%) or in changes on HAM-D scores. Although 37.5% of the participants experienced partial response or remitted in phase 2, neither form of adjunctive psychotherapy

    Full Text Available In this study we assessed differences in new and repeat prescriptions of psycho-tropics between patients receiving prescriptions for drugs to treat a common chronic disease and people without such prescriptions. The study used the databases of two Dutch health insurance companies (3 million people. We selected all Dutch men and women aged 45 and older who were registered for six consecutive years (1999–2004. Our analyses both found a consistent relation between psycho-tropics on the one hand and physical illness on the other. People with multi-morbidity were prescribed these drugs most often, especially men and those younger than 65. Epidemiological studies showed a prevalence of depression among people with multi-morbidity to be twice as high as among people without such conditions. According to recent guidelines non-drug treatment may be the first therapy option for patients with non severe depression. If prescribed for a long time, benzodiazepine prescriptions are especially known to be addictive. Our data raise the question to what extent patients with a chronic physical disease suffering from co-occurring mental problems are prescribed psycho-tropics in accord with the guidelines that also advise mental support in case of non severe mental problems. Further research can answer this important question.

    Full Text Available Chronic constipation is a common functional gastrointestinal disorder that affects patients of all ages. In 2007, a consensus group of 10 Canadian gastroenterologists developed a set of recommendations pertaining to the management of chronic constipation and constipation-dominant irritable bowel syndrome. Since then, tegaserod has been withdrawn from the Canadian market. A new, highly selective serotonin receptor subtype 4 agonist, prucalopride, has been examined in several large, randomized, placebo-controlled trials demonstrating its efficacy and safety in the management of patients with chronic constipation. Additional studies evaluating the use of stimulant laxatives, polyethylene glycol and probiotics in the management of chronic constipation have also been published. The present review summarizes the previous recommendations and new evidence supporting different treatment modalities – namely, diet and lifestyle, bulking agents, stool softeners, osmotic and stimulant laxatives, prucalopride and probiotics in the management of chronic constipation. A brief summary of lubiprostone and linaclotide is also presented. The quality of evidence is presented by adopting the Grading of Recommendations, Assessment, Development and Evaluation system. Finally, a management pyramid for patients with chronic constipation is proposed based on the quality of evidence, impact of each modality on constipation and on general health, and their availabilities in Canada.

    This study evaluated the relationship of sociotropic and autonomous personality traits with response to pharmacotherapy for 217 depressed outpatients using the Sociotropy-Autonomy Scale. Sociotropy was related to nonendogenous depression, whereas autonomy was related to endogenous depression. Subjects who had high autonomous-low sociotropic traits showed greater response to antidepressants (and greater drug-placebo differences) than those who had high sociotropic-low autonomous traits (who showed no drug-placebo differences). Hierarchical multiple regression analysis showed that the sociotropy-autonomy, but not the endogenous-nonendogenous, distinction was a predictor of drug treatment response. The combination of endogeneity and autonomy predicted response to placebo. If replicated, these findings may enable better matching of patient traits to various treatment modalities for depression.

    We attempted to investigate whether dehydroepiandrosterone sulfate (DHEA-S) levels are associated with remission of major depressive disorder by assessing scores on the 17-Item Structured Interview Guide for the Hamilton Depression before and after antidepressant treatment. Plasma DHEA-S levels in 24 patients diagnosed with major depressive disorder on the basis of Diagnostic and Statistical Manual of Mental Disorders, fourth edition (text revision) before and after antidepressant treatment, and 24 healthy, gender-matched, and age-matched controls were measured using a radioimmunoassay kit. Plasma DHEA-S levels in patients were significantly higher than those in healthy controls. In patients who achieved remission after antidepressant treatment, plasma DHEA-S levels significantly declined compared with the levels before treatment. A significant correlation was observed between changes in DHEA-S levels and Absence of Depressive and Anxious Mood scores, which are calculated from the 2-Item Structured Interview Guide for the Hamilton Depression rating as follows: severity of depressive mood and anxiety in patients before and after antidepressant treatment. These findings suggest that plasma DHEA-S levels can be used as a putative indicator of the state of remission in patients with major depressive disorder. Copyright © 2014 John Wiley & Sons, Ltd.

    Major depressive disorder (MDD) is associated with a significantly elevated risk of developing serious medical illnesses such as cardiovascular disease, immune impairments, infection, dementia and premature death. Previous work has demonstrated immune dysregulation in subjects with MDD. Using genome-wide transcriptional profiling and promoter-based bioinformatic strategies, we assessed leukocyte transcription factor (TF) activity in leukocytes from 20 unmedicated MDD subjects versus 20 age-, sex- and ethnicity-matched healthy controls, before initiation of antidepressant therapy, and in 17 of the MDD subjects after 8 weeks of sertraline treatment. In leukocytes from unmedicated MDD subjects, bioinformatic analysis of transcription control pathway activity indicated an increased transcriptional activity of cAMP response element-binding/activating TF (CREB/ATF) and increased activity of TFs associated with cellular responses to oxidative stress (nuclear factor erythroid-derived 2-like 2, NFE2l2 or NRF2). Eight weeks of antidepressant therapy was associated with significant reductions in Hamilton Depression Rating Scale scores and reduced activity of NRF2, but not in CREB/ATF activity. Several other transcriptional regulation pathways, including the glucocorticoid receptor (GR), nuclear factor kappa-B cells (NF-κB), early growth response proteins 1–4 (EGR1–4) and interferon-responsive TFs, showed either no significant differences as a function of disease or treatment, or activities that were opposite to those previously hypothesized to be involved in the etiology of MDD or effective treatment. Our results suggest that CREB/ATF and NRF2 signaling may contribute to MDD by activating immune cell transcriptome dynamics that ultimately influence central nervous system (CNS) motivational and affective processes via circulating mediators.

    Modelling key endophenotypes can be a powerful approach to gain insight into mechanisms underlying the aetiology and pathophysiology of neuropsychiatric disorders. Based on evidence of stress hormone system dysregulations in depression, the Stress Reactivity (SR) mouse model has been generated by a selective breeding approach for extremes in HPA axis reactivity, resulting in high (HR), intermediate (IR) and low (LR) reactive mice. The characterisation of their phenotypic alterations has highlighted many similarities of HR and LR mice with the melancholic and atypical depression, respectively. We therefore aimed to examine whether the antidepressant fluoxetine (10 mg/kg/day i.p., 4-5 weeks) can ameliorate the phenotypic characteristics of HR and LR mice in neuroendocrine functions (HPA axis basal activity, stress reactivity, negative feedback), emotional reactivity/coping-strategy (open field, forced swim tests), spatial learning/memory (Morris water-maze) and hippocampal neurogenesis. Line differences in HPA axis reactivity were maintained under fluoxetine treatment. However, we observed fluoxetine effects on glucocorticoid-induced negative feedback, stress-coping behaviours, cognitive functions and neurogenesis. Specifically, our results revealed line-dependent consequences of fluoxetine treatment: (1) an amelioration of the 'melancholic-like' features of HR mice (reversing the negative feedback resistance, the hyperactive coping style and the memory deficits; increasing hippocampal neurogenesis); (2) an exacerbation of the phenotypic deviations of LR mice (increasing their pronounced negative feedback and passive coping style). Thus, these findings support the predictive validity of antidepressant treatment in the HR mouse line and emphasize the translational value of the SR mouse model for the development of therapeutic strategies based on endophenotype-driven classifications.

    2017-03-27

    Approximately 50% of depressed individuals fail to achieve remission with first-line antidepressant drugs and a third remain treatment-resistant. When first-line antidepressant treatment is unsuccessful, second-line strategies include dose optimisation, switching to another antidepressant, combination with another antidepressant, or augmentation with a non-antidepressant medication. Much of the evidence for the efficacy of augmentation strategies comes from studies using lithium to augment the effects of tricyclic antidepressants. The neural circuitry underlying the therapeutic effects of lithium augmentation is not yet fully understood. Recently, we reported that chronic treatment with a combination of lithium and the antidepressant desipramine, exerted antidepressant-like behavioural effects in a mouse strain (BALB/cOLaHsd) that did not exhibit an antidepressant-like behavioural response to either drug alone. In the present study, we used this model in combination with ΔFosB/FosB immunohistochemistry to identify brain regions chronically affected by lithium augmentation of desipramine when compared to either treatment alone. The data suggest that the dorsal raphe nucleus and the CA3 regions of the dorsal hippocampus are key nodes in the neural circuitry underlying antidepressant action of lithium augmentation of desipramine. These data give new insight into the neurobiology underlying the mechanism of lithium augmentation in the context of treatment-resistant depression.

  20. GABA/glutamate co-release controls habenula output and is modified by antidepressant treatment

    The lateral habenula (LHb), a key regulator of monoaminergic brain regions, is activated by negatively-valenced events. Its hyperactivity is associated with depression. While enhanced excitatory input to the LHb has been linked to depression, little is known about inhibitory transmission. We discovered that GABA is co-released with its functional opponent, glutamate, from long-range basal ganglia inputs (which signal negative events) to limit LHb activity in rodents. At this synapse, the balance of GABA/glutamate signaling is shifted towards reduced GABA in a model of depression and increased GABA by antidepressant treatment. GABA and glutamate co-release therefore controls LHb activity, and regulation of this remarkable form of transmission may be important for determining the impact of negative life events on mood and behavior.

    Previous researches found that apigenin exerted antidepressant-like effects in rodents. However, it is unclear whether the neurotrophic system is involved in the antidepressant-like effects of apigenin. Our present study aimed to explore the neurotrophic related mechanism of apigenin in depressive-like mice induced by chronic corticosterone treatment. Mice were repeatedly injected with corticosterone (40 mg/kg) subcutaneously (s.c) once daily for consecutive 21 days. Apigenin (20 and 40 mg/kg) and fluoxetine (20 mg/kg) were administered 30 min prior to the corticosterone injection. The behavioral tests indicated that apigenin reversed the reduction of sucrose preference and the elevation of immobility time in mice induced by chronic corticosterone treatment. In addition, the increase in serum corticosterone levels and the decrease in hippocampal brain-derived neurotrophic factor (BDNF) levels in corticosterone-treated mice were also ameliorated by apigenin administration. Taken together, our findings intensively confirmed the antidepressant-like effects of apigenin and indicated that the antidepressant-like mechanism of apigenin was mediated, at least partly by up-regulation of BDNF levels in the hippocampus.

    Strong evidence suggests that antidepressants work by induction of neuroplastic changes mediated through regulation of brain-derived neurotrophic factor (BDNF). This study was undertaken to investigate the time-course of the effect of three antidepressants; fluoxetine, imipramine and venlafaxine, which differentially affect monoamine reuptake, on BDNF mRNA expression in the hippocampus. The consequences of increased BDNF in the hippocampus are still indefinite. Here, we also determined the effects on the expression of two other genes (synaptophysin and growth-associated protein-43 (GAP-43)) known to be involved in synapse formation and axonal growth and likely regulated by BDNF. The effects were determined in rats after sub-chronic (7 days) and chronic (14 and 21 days) treatment using semi-quantitative in situ hybridisation. BDNF mRNA levels in the dentate gyrus (DG) were increased after treatment with venlafaxine (7, 14 and 21 days) and imipramine (14 and 21 days), but not after treatment with fluoxetine, indicating that stimulation of BDNF mRNA expression is dependent on the pharmacological profile and on the time-course of drug treatment. A transient increase in synaptophysin mRNA was observed after treatment with venlafaxine and fluoxetine whereas imipramine had no effect. In the CA3 region a reduction of GAP-43 mRNA was observed after treatment with imipramine (21 days) and fluoxetine (7 and 14 days). These results suggest that venlafaxine and imipramine, but not fluoxetine, induce neuroplastic effects in the hippocampus through stimulation of BDNF mRNA expression, and that the effect on BDNF is not directly translated into regulation of synaptophysin and GAP-43 mRNA.

    Several clinical reports have documented a beneficial effect of the addition of a low dose of risperidone to the ongoing treatment with antidepressants, in particular selective serotonin reuptake inhibitors (SSRI), in the treatment of drug-resistant depression and treatment-resistant anxiety disorders. In the present study, we investigated the effect of treatment with the antidepressant escitalopram (SSRI) given separately or jointly with a low dose of risperidone (an atypical antipsychotic) in the forced swim test and in the elevated plus-maze test in rats. The obtained results showed that escitalopram at doses of 2.5 or 5 mg/kg evoked antidepressant-like effect in the forced swim test. Moreover, risperidone at low doses (0.05 or 0.1 mg/kg) enhanced the antidepressant-like activity of escitalopram (1 mg/kg) in this test by increasing the swimming time and decreasing the immobility time in those animals. WAY 100635 (a serotonin 5-HT1A receptor antagonist) at a dose of 0.1 mg/kg abolished the antidepressant-like effect induced by co-administration of escitalopram and risperidone. The active behavior in that test did not reflect an increase in general activity, since the combined treatment with escitalopram and risperidone failed to enhance the exploratory activity of rats. In the following experiment, we showed that escitalopram (5 mg/kg) and mirtazapine (5 or 10 mg/kg) or risperidone (0.1 mg/kg) induced an anxiolytic-like effect in the elevated plus-maze test, and the combined treatment with an ineffective dose of risperidone (0.05 mg/kg) enhanced the anxiolytic-like effects of escitalopram (2.5 mg/kg) or mirtazapine (1 and 2.5 mg/kg) in this test. The obtained results suggest that risperidone applied at a low dose enhances the antidepressant-like activity of escitalopram in the forced swim test, and that 5-HT1A receptors may play some role in these effects. Moreover, a low dose of risperidone may also enhance the anxiolytic-like action of the studied

    Antidepressant treatment attenuates behavioral changes induced by uncontrollable stress. The periaqueductal gray matter (PAG) is proposed to be a brain site involved in the behavioral responses to uncontrollable stress and antidepressant effects. The main goal of the present study was to investigate the effect of antidepressant treatment on the pattern of neural activation of the PAG along its mediolateral and rostrocaudal subregions after a forced swim stress episode. Male Wistar rats were sub-acutely treated with desipramine (a selective noradrenaline re-uptake blocker, three injections of 10 mg/kg in 24 h) or clomipramine (a non-selective serotonin and noradrenaline re-uptake blocker, three injections of 10 mg/kg in 24 h) and submitted to the forced swimming test (FST). Two hours after the test their brain were removed for Fos immunohistochemistry. Fos-like immunoreactivity (FLI) in rostral, intermediate and caudal portions of dorsomedial (dmPAG), dorsolateral (dlPAG), lateral (lPAG) and ventrolateral (vlPAG) PAG were quantified by a computerized system. The FST session increased FLI in most parts of the PAG. Previous treatment with desipramine or clomipramine reduced FLI in all columns of the PAG. FLI in the PAG correlated positively with to the immobility time and negatively with to climbing behavior scored during the test. These results indicate that neurons in the PAG are activated by uncontrollable stress. Moreover, inhibitory action of antidepressants on this activity may be associated with the anti-immobility effects of these drugs in the FST.

    The present study examined the relationship between religiosity/spirituality and treatment response to antidepressant medication (citalopram). One-hundred and forty-eight Caucasian and African-American adults with uncomplicated major depression were treated with citalopram (20–60mg/day) over an 8-week period in a prospective multi-site clinical trial. Treatment response was assessed weekly with the Hamilton Rating Scale for Depression. Religiosity (i.e., religious behaviours) and spirituality (i.e., spiritual well-being) were assessed at Week 3. No significant associations between spirituality and treatment response were found; however, there was a strong curvilinear relationship between religiosity and treatment response. Compared to lower or higher levels of religiosity, a moderate level of religiosity was significantly associated with a higher likelihood of remission and greater reduction in severity of depression. This association was independent of social support, ethnicity, gender, education, and baseline depression severity. A moderate amount of religiosity appears to be independently associated with an enhanced treatment response to citalopram. PMID:22736954

    This is an update of a Cochrane review first published in The Cochrane Library in Issue 4, 2006 and previously updated in 2009.Tinnitus is described as the perception of sound or noise in the absence of real acoustic stimulation. It has been compared with chronic pain, and may be associated with depression or depressive symptoms which can affect quality of life and the ability to work. Antidepressant drugs have been used to treat tinnitus in patients with and without depressive symptoms. To assess the effectiveness of antidepressants in the treatment of tinnitus and to ascertain whether any benefit is due to a direct tinnitus effect or a secondary effect due to treatment of concomitant depressive states. We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; PsycINFO; CINAHL; Web of Science; BIOSIS; ICTRP and additional sources for published and unpublished trials. The date of the most recent search was 5 January 2012. Randomised controlled clinical studies of antidepressant drugs versus placebo in patients with tinnitus. Two authors critically appraised the retrieved studies and extracted data independently. Where necessary we contacted study authors for further information. Six trials involving 610 patients were included. Trial quality was generally low. Four of the trials looked at the effect of tricyclic antidepressants on tinnitus, investigating 405 patients. One trial investigated the effect of a selective serotonin reuptake inhibitor (SSRI) in a group of 120 patients. One study investigated trazodone, an atypical antidepressant, versus placebo. Only the trial using the SSRI drug reached the highest quality standard. None of the other included trials met the highest quality standard, due to use of inadequate outcome measures, large drop-out rates or failure to separate the effects on tinnitus from the effects on symptoms of anxiety and depression.

    Major depressive disorder is a prevalent psychiatric disorder in primary care, associated with impaired patient functioning and well-being. Fluoxetine is a selective serotonin-reuptake inhibitors (SSRIs) and is a commonly prescribed antidepressant compound. Its action is primarily attributed to selective inhibition of the reuptake of serotonin (5-hydroxytryptamine) in the central nervous system. Objectives ; the aims of this study were two-fold: (1) to determine the usefulness for investigation of the transcription profiles in depression patients, and (2) to assess the differences in gene expression profiles between positive response group and negative response groups by fluoxetine treatment. This study included 53 patients with major depression (26 in positive response group with antidepressant treatment, 27 in negative response group with antidepressant treatment), and 53 healthy controls. To examine the difference of gene expression profile in depression patients, radioactive complementary DNA microarrays were used to evaluate changes in the expression of 1,152 genes in total. Using 33p-labeled probes, this method provided highly sensitive gene expression profiles including brain receptors, drug metabolism, and cellular signaling. Gene transcription profiles were classified into several categories in accordance with the antidepressant gene-regulation. The gene profiles were significantly up-(22 genes) and down-(16 genes) regulated in the positive response group when compared to the control group. Also, in the negative response group, 35 genes were up-regulated and 8 genes were down-regulated when compared to the control group. Consequently, we demonstrated that radioactive human cDNA microarray is highly likely to be an efficient technology for evaluating the gene regulation of antidepressants, such as selective serotonin-reuptake inhibitors (SSRIs), by using high-throughput biotechnology.

  8. Endoscopic treatment of chronic pancreatitis

    2007-01-01

    Treatment of chronic pancreatitis has been exclusively surgical for a long time. Recently, endoscopic therapy has become widely used as a primary therapeutic option.Initially performed for drainage of pancreatic cysts and pseudocysts, endoscopic treatments were adapted to biliary and pancreatic ducts stenosis. Pancreatic sphincterotomy which allows access to pancreatic ducts was firstly reported. Secondly, endoscopic methods of stenting, dilatation, and stones extraction of the bile ducts were applied to pancreatic ducts. Nevertheless,new improvements were necessary: failures of pancreatic stone extraction justified the development of extra-corporeal shock wave lithotripsy; dilatation of pancreatic stenosis was improved by forage with a new device; moreover endosonography allowed guidance for celiac block, gastro-cystostomy, duodeno-cystostomy and pancreatico-gastrostomy. Although endoscopic treatments are more and more frequently accepted,indications are still debated.

    To investigate whether the extract of Dendrobium nobile Lindl (DNL) has an antidepressant effect on chronic unpredictable mild stress (CUMS)-induced depressive mice, 72 BALB/c male mice were randomly divided into the control group, the CUMS model group, the extract of DNL groups (50, 100 and 200 mg/kg DNL, i.g.) and the paroxetine group (10 mg/kg, i.g.). The different doses of DNL or the paroxetine was administered orally once daily to CUMS mice for 8 weeks (containing two-week preventive medication before the modeling). The same volume of distilled water was given to the control group and the CUMS group. Except for the control group, the other mice were exposed to chronic stress for 35 days. Behavioral tests were performed by using the sucrose preference test (SPT), the novelty-suppressed feeding (NSF) test, the tail suspension test (TST), and the forced swim test (FST). The levels of dopamine (DA) and 5-hydroxytryptamine (5-HT) were measured by the liquid chromatography-mass spectrometer (LC-MS)/MS. Compared with the control group, obvious behavioral changes were observed in the CUMS group after 5-week CUMS, including a decrease in the sucrose consumption, an increase in the latency to feeding in the NSF test and a prolongation of the immobility time in the TST. Compared with the CUMS group, the application of DNL resulted in a dose-dependent increase in sucrose consumption (P 0.05). In addition, in the hippocampus and cortex, the levels of 5-HT and DA were significantly decreased in the CUMS group compared with the control group (P < 0.05). In comparison with the CUMS group, paroxetine obviously increased the DA levels in the hippocampus and the cortex and the 5-HT level in the hippocampus (P < 0.05). DNL (50 and 200 mg/kg) significantly increased the DA level in cerebral cortex of the brain, and DNL (100 and 200 mg/kg) increased the DA level in the hippocampus. The 5-HT level in the 200 mg/kg DNL group was notably increased in both two brain regions (P < 0

    BACKGROUND: It has been demonstrated that patients with functional dyspepsia have experiences social life stress events, and accompanied by psychological disorders, mainly manifested as depression and anxiety.Mental factors can lead to excessive gastrointestinal consensual reaction, and result in different brain-gut axis disturbance, and then cause the gastrointestinal sensorimotor abnormality and endocrine changes.OBJECTIVE: To observe the effect of antidepressant treatment on the changes of water load and serum cortisol in patients with functional dyspepsia, and analyze the therapeutic mechanism.DESIGN: A comparative observation.SETTING: The First Affiliated Hospital o Zhengzhou University.PARTICIPANTS: Forty-five patients with functional dyspepsia accompanied by depression were selected from the Department of Gastroenterology, the First Affiliated Hospital of Zhengzhou University from July 2004 to July 2006, and they were 25 - 65 years of age, and their disease courses ranged 1 - 10 years. They were all accorded with the diagnostic standards for Rome Ⅱ functional dyspepsia functional dyspepsia. As the patients' will, they were divided into treatment group (n =30, 12 males and 18 females) and control group (n =15, 6 males and 9 females), and there were no significant differences in the data between the two groups (P > 0.05). The programs were discussed and agreed by the committee of medical ethics of the First Affiliated Hospital of Zhengzhou University. Informed contents were obtained from all the patients.METHODS: In the treatment group, the patients were treated with venlafaxine sustained release capsule (75 mg per day), and those with sleep disorder were added by benzodiazepines (alprazolam). In the control group, the patients were given routine treatments of antacid, prokinetics, etc. Before and after 8-week treatment, the following examinations were performed: ① The gastrointestinal symptoms were assessed according to the symptoms; ② The severity of

    The paper will highlight and discuss some of the important issues and controversies of current depression treatment like the efficacy of antidepressants, their effect on suicidality, their place in a complex psychiatric treatment strategy including psychotherapy and other psychosocial activities. The efficacy of antidepressants is clinically significant, but often monotherapy with one drug has to be followed by others or by comedication/augmentation therapy approaches. Psychosocial therapy, predominantly focused on psychotherapeutic strategies, can also contribute in a relevant way to the therapeutic success. Generally, antidepressants reduce suicidality, but under special conditions like young age or personality disorder, they can also be harmful in this respect. However, under the conditions of good clinical practice, the risk-benefit relationship of treatment with antidepressants can be judged as favourable. In addition, the paper tries to analyse the question about how to reach individualised, evidence and value oriented decision making in the complex treatment of depressive patients. The capacity of psychiatrists to individualise treatment decisions in terms of "the right drug/treatment for the right patient" is still restricted since there are currently not enough powerful clinical or biological predictors, which help to achieve this goal. There is hope that in future pharmacogenetics will contribute significantly to a personalised treatment. The ideal that all steps of classical decision making can be based on the strict rule of evidence-based medicine is far away from reality. Individualised decision making is so complex that the rigorous expectations of evidence-based medicine can hardly be fulfilled. Finally, it should be considered that clinical decision making is not only evidence but also value oriented.

    Full Text Available Eiji Kirino, Masao GitohDepartment of Psychiatry, Juntendo University, School of Medicine, Shizuoka, JapanAbstract: Suicide is a serious social problem in many countries, including Japan. The majority of people who commit suicide suffer from depression. Suicide attempt patients suffering from serious physical injuries are initially treated in hospital emergency departments. The present post hoc analysis examined data from patients admitted to an emergency hospital for treatment of physical injuries, resulting from a suicide attempt, and initial psychiatric treatment for depression and prevention of future suicide attempts. The effects on depressive symptoms were studied in two groups of patients using the 17-item Hamilton depression scale (HAMD. One group (n = 6 had received intravenous tricyclic antidepressants (TCA (amitriptyline or clomipramine while the other group (n = 7 had been treated orally with milnacipran, a serotonin and norepinephrine reuptake inhibitor antidepressant. Prior to treatment the four highest scoring items on the HAMD scale were the same in both groups namely, item 1 (depressed mood, item 3 (suicidality, item 7 (interest in work and activities, and item 10 (psychic anxiety. After 1 week of treatment, mean global HAMD scores were significantly reduced in both groups. Treatment resulted in a significant reduction of five HAMD items in the TCA group, whereas in the milnacipran group 12 HAMD items were significantly reduced. Suicidality (item 3 was significantly improved by 1 week treatment with milnacipran, but not by TCAs. Milnacipran rapidly improved a wide range of depressive symptoms, including suicidality within the first week. The improvement with milnacipran would appear to be, at least, equivalent to that achieved with TCAs, possibly affecting a wider range of symptoms. Since milnacipran has been shown in comparative studies to be better tolerated than TCAs, this antidepressant offers an interesting option for the

    Full Text Available Abstract Background The presenting symptoms of depression can be influenced by cultural differences. This study was conducted to compare the presenting symptoms and response to antidepressant medication of patients in Sweden and Turkey, two culturally different European countries. Methods Recruitment was triggered when adult patients were diagnosed with a depressive or anxiety disorder by a primary care physician and prescribed an antidepressant. Physicians and patients recorded presenting symptoms and completed relevant questionnaires just before and 8 weeks after starting treatment with an antidepressant. These included the Hospital Anxiety and Depression Scale (HADS, the Clinical Global Impressions (CGI scale, the Sheehan Disability Scale (SDS, and Likert scales gauging the importance of physical and psychological symptoms. Patients also rated severity of prominent symptoms (depression, anxiety, stress, sleep and pain from zero to ten. The outcomes were compared between patients from Sweden and Turkey using Fisher's Exact test and two-sample t-tests. Results The study was conducted in 460 patients (107, 23.3% in Sweden; 353, 76.7% in Turkey. Presenting symptoms differed between Sweden and Turkey, with Turkish patients more likely to present with physical symptoms, and report a higher number of physical symptoms (mean 2.4 vs. 1.4, p Conclusions The presenting symptoms of patients diagnosed with a depressive or anxiety disorder by a primary care physician and prescribed an antidepressant differ between Turkey and Sweden. Patients in Turkey were more likely to present with physical symptoms than patients in Sweden and present with more physical symptoms. After 8 weeks of antidepressant treatment, the improvement from baseline was greater in Turkish patients, and this was reflected in their improved functioning.

Black-Right-Pointing-Pointer Hydroxyl radical is the most significant contributor to the degradation. Black-Right-Pointing-Pointer Excited state dissolved organic matter also plays a significant role for duloxetine. Black-Right-Pointing-Pointer Tentative reaction byproducts are identified. - Abstract: Antidepressant pharmaceuticals have recently been detected at low concentrations in wastewater and surface water. This work reports studies of the direct and indirect photochemical fate and treatment by advanced oxidation of three antidepressant compounds (duloxetine, venlafaxine and bupropion) in solutions of humic acid in order to elucidate their behavior in the natural environment prior to reaching a water treatment facility and potentially entering a potable water supply. Humic acid solution was prepared by adding to distilled water a known amount of organic matter as a photosensitizer. All three antidepressants react very rapidly with hydroxyl radicals ({center_dot}OH) and hydrated electrons (e{sup -}{sub aq}) with rate constants of {approx}10{sup 8} to 10{sup 10} M{sup -1} s{sup -1}, but significantly slower with singlet oxygen ({sup 1}{Delta}O{sub 2}) ({approx}10{sup 3} to 10{sup 5} M{sup -1} s{sup -1}). The steady-state concentrations of {center_dot}OH and {sup 1}{Delta}O{sub 2}, in a sample of humic acid solution were measured and used with the second order rate constants to show that the hydroxyl radical was an order of magnitude more effective than the singlet oxygen in the solar-induced photochemical degradation of the antidepressants. Excited state dissolved organic matter also accounted for a substantial portion of degradation of duloxetine, decreasing its half-life by 27% under solar irradiation. Several reaction pathways and by-products arising from the photodegradation were identified using gamma-irradiation followed by LC

    The most frequent combinations are SSRIs and tricyclic antidepressants. The active principle most widely combined is fluoxetine. Conclusions. The prevalence of use of antidepressant combination therapy is 2.2% of the global sample and 8.3% of treated patients. Other than duration of the depressive episode, no clinical characteristics exclusive to patients who received combination rather than monotherapy were found. Our study found that the most frequent combination is SSRIs + TCAs, also being the most studied.

    Objective Brain-derived neurotrophic factor (BDNF) and its specific receptor, tropomyosin-related kinase (TrkB), play important roles in treating depression. In this experiment, we examined whether 7,8-dihydroxyflavone, a novel potent TrkB agonist, could reverse the behavioral and biochemical abnormalities induced by the chronic mild stress (CMS) paradigm in rats. Methods SD rats were exposed to a battery of stressors for 56 days. 7,8-dihydroxyflavone (5 and 20 mg/kg) were administered intraperitoneally during the last 28 days of the CMS paradigm. Rats were tested in sucrose consumption test (SCT), forced-swimming test (FST) and elevated T-maze (ETM). Serum corticosterone levels and hippocampal BDNF levels of the rats were measured. Results Four-week CMS on the rats induced their depression-like behavior in SCT. The CMS-reduced sucrose consumption was reversed starting from 7 days after the 7,8-dihydroxyflavone (20 mg/kg) treatment and remained across the subsequent treatment regime. 7,8-dihydroxyflavone, when given at 5 mg/kg for 3 weeks, reduced the immobility time in the FST in the CMS-subjected rats. Additionally, the 4-week treatment with 7,8-dihydroxyflavone (20 mg/kg) attenuated the CMS-induced increase in anxiety-like behavior in the ETM. For the CMS-subjected rats, 7,8-dihydroxyflavone treatment dose-dependently reduced their serum corticosterone levels but increased their hippocampal BDNF levels only at 5 mg/kg. Conclusion 7,8-dihydroxyflavone was beneficial for both depression and anxiety-like behaviors, and may exert fast-onset antidepressant effects. This provides a new insight into the pharmacological management of depression.

    The widely held clinical view of 'antidepressants' as highly effective and specific for the treatment of all types of depressive disorders is exaggerated. This sobering conclusion is supported by recent findings from the NIMH-sponsored STEP-BD and STAR*D projects. Antidepressants have limited short-term efficacy in unipolar depressive disorders and less in acute bipolar depression; their long-term prophylactic effectiveness in recurrent unipolar major depression remains uncertain, and is doubtful in recurrent bipolar depression. These limitations may, in part, reflect the excessively broad concept of major depression as well as unrealistic expectations of universal efficacy of drugs considered 'antidepressants.' Treatment-refractory depression may reflect failure to distinguish depressive conditions, particularly bipolar disorder, that are inherently less responsive to antidepressants. Antidepressants probably should be avoided in bipolar depression, mixed manic-depressive states, and in neurotic depression. Expectations of antidepressants for specific types of patients with symptoms of depression or anxiety require critical re-evaluation. A revival of the concept of neurotic depression would make it possible to identify patients with mild-to-moderate, chronic or episodic dysthymia and anxiety who are unlikely to benefit greatly from antidepressants. Diagnostic criteria for a revival of the concept of neurotic depression are proposed.

    2014-07-01

    Treatment-resistant depression (TRD) is used as a descriptive or diagnostic term and has generated many management guidelines weighting antidepressant (AD) therapy, but which may be an inappropriate paradigm for the nonmelancholic disorders where psychotherapy may be a more salient modality. This study sought to evaluate the effectiveness of psychological therapy in patients whose nonmelancholic depressive condition had been resistant to at least 2 ADs. Principal analyses compared 32 patients, diagnosed with a nonmelancholic depression who received 12 weeks of psychological therapy, with a small control group. Comparative analyses failed to find a distinct therapeutic effect, leading to an extension study pursuing candidate explanatory factors for this lack of response, including psychosocial factors. While our sample showed a 41% response and 22% remission rate to psychotherapy, their improvement pattern was similar to the control group, thus arguing against any specific therapeutic benefit. Explanatory factors nominated by the treating psychologist weighted personality issues for 35% of the patients, distal stressors for 22%, and comorbid anxiety conditions for 18%. When sample members were compared with an age- and sex-matched sample of patients with nonmelancholic depression who improved distinctly during a similar 12-week period, rates of such putative personality, stress, and anxiety risk factors did not differ, arguing against the likelihood of these factors compromising improvement. Patients with nonmelancholic TRD also failed to demonstrate a clear response to a psychotherapeutic approach, while our pursuit of clinically explanatory variables was not supported empirically.

    2016-09-16

    Depression is a significant public health problem for which currently available medications, if effective, require weeks to months of treatment before patients respond. Previous studies have shown that the G protein responsible for increasing cAMP (Gαs) is increasingly localized to lipid rafts in depressed subjects and that chronic antidepressant treatment translocates Gαs from lipid rafts. Translocation of Gαs, which shows delayed onset after chronic antidepressant treatment of rats or of C6 glioma cells, tracks with the delayed onset of therapeutic action of antidepressants. Because antidepressants appear to specifically modify Gαs localized to lipid rafts, we sought to determine whether structurally diverse antidepressants accumulate in lipid rafts. Sustained treatment of C6 glioma cells, which lack 5-hydroxytryptamine transporters, showed marked concentration of several antidepressants in raft fractions, as revealed by increased absorbance and by mass fingerprint. Closely related molecules without antidepressant activity did not concentrate in raft fractions. Thus, at least two classes of antidepressants accumulate in lipid rafts and effect translocation of Gαs to the non-raft membrane fraction, where it activates the cAMP-signaling cascade. Analysis of the structural determinants of raft localization may both help to explain the hysteresis of antidepressant action and lead to design and development of novel substrates for depression therapeutics.

    Desvenlafaxine succinate (DVS) is one of several serotonin-norepinephrine reuptake inhibitors (SNRIs). Others are venlafaxine hydrochloride, milnacipran, and duloxetine. Desvenlafaxine has been approved by the US Food and Drug Administration (FDA) for the treatment of major depressive disorder (MDD) based on a number of randomized, placebo-controlled clinical trials. Clinical studies have investigated the efficacy of DVS in doses ranging from 50 to 400 mg/day for the treatment of MDD in adult outpatients. The effects of DVS 50 mg/day have been clearly distinguished from placebo in the reduction of MDD symptoms in such clinical trials. No additional therapeutic benefits were found at doses > 50 mg/day. The recommended dose of DVS ranges from 50 to 100 mg. Desvenlafaxine is currently the third SNRI approved by the FDA for this indication. Preliminary evidence also suggests the clinical usefulness of DVS in the treatment of vasomotor symptoms of menopause, anxiety symptoms, and painful physical symptoms. The modified pharmacokinetic and pharmacodynamic profiles of DVS differentiate this drug from the original product, venlafaxine. Significant points of difference, compared with venlafaxine, are once-daily dosing and the achievement of steady-state plasma concentrations within 4 to 5 days. To summarize, current evidence indicates that DVS has proven efficacy, acceptable safety and tolerability profiles, convenient dosing, and minimal impact on the cytochrome P450 enzyme system. A reduced risk for pharmacokinetic drug interactions is a potential advantage over other selective serotonin noradrenaline reuptake inhibitors. Desvenlafaxine succinate has demonstrated its efficacy for treating MDD but its variable efficacy, as shown in individual studies, limited long-term data, and its different risk-to-benefit ratio compared with earlier antidepressants, means that further investigation of this drug is necessary.

  10. Is exercise an alternative treatment for chronic insomnia?

    Directory of Open Access Journals (Sweden)

    Giselle Soares Passos

    Full Text Available The purposes of this systematic/critical review are: 1 to identify studies on the effects of exercise on chronic insomnia and sleep complaints in middle-aged and older adults and to compare the results of exercise with those obtained with hypnotic medications and 2 to discuss potential mechanisms by which exercise could promote sleep in insomniac patients. We identified studies from 1983 through 2011 using MEDLINE, SCOPUS and Web of Science. For systematic analyses, only studies assessing the chronic effects of exercise on sleep in people with sleep complaints or chronic insomnia were considered. We used the following keywords when searching for articles: insomnia, sleep, sleep complaints, exercise and physical activity. For a critical review, studies were selected on the effects of exercise and possible mechanisms that may explain the effects of exercise on insomnia. We identified five studies that met our inclusion criteria for systematic review. Exercise training is effective at decreasing sleep complaints and insomnia. Aerobic exercise has been more extensively studied, and its effects are similar to those observed after hypnotic medication use. Mechanisms are proposed to explain the effects of exercise on insomnia. There is additional documented evidence on the antidepressant and anti-anxiety effects of exercise. Exercise is effective to decrease sleep complaints and to treat chronic insomnia. Exercise presented similar results when compared with hypnotics; however, prospective studies comparing the effects of exercise with medical and non-medical treatments are warranted before including exercise as a first-line treatment for chronic insomnia are necessary.

    We previously reported that combined fluoxetine administration at antidepressant doses renders additive antidepressant effects, whereas non-antidepressant doses potentiate the omega-3 fatty acid antidepressant effect. In the present study, we aimed to evaluate putative pharmacokinetic and brain omega-3 fatty acid-related aspects for fluoxetine potentiation of omega-3 fatty acid antidepressant effect in rats. Coadministration of omega-3 fatty acids with a non-antidepressant dose of fluoxetine (1 mg/kg day) failed to affect both brain fluoxetine concentration and norfluoxetine plasma concentration profile. Fluoxetine plasma concentrations remained below the sensitivity limit of the detection method. Either antidepressant (10 mg/kg day) or non-antidepressant (1 mg/kg day) doses of fluoxetine in combination with omega-3 fatty acids increased hippocampal docosapentaenoic acid (DPA, 22:5 omega-3) levels. Although individual treatments had no effects on DPA concentration, DPA increase was higher when omega-3 were combined with the non-antidepressant dose of fluoxetine. Chronic DPA administration exerted antidepressant-like effects in the forced swimming test while increasing hippocampal docosahexaenoic (22:6 omega-3) and DPA levels. Our results suggest no pharmacokinetic interaction and reveal specific hippocampal DPA changes after fluoxetine and omega-3 combined treatments in our experimental conditions. The DPA role in the synergistic effect of fluoxetine and omega-3 combined treatments will be for sure the focus of future studies. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci 103:3316-3325, 2014.

    Most currently available antidepressants target monoamine neurotransmitter function. However, a purely neurotransmitter-based explanation for antidepressant drug action is challenged by the delayed clinical onset of most agents and the need to explain how neurochemical changes reverse the many different symptoms of depression. Novel approaches to understanding of antidepressant drug action include a focus on early changes in emotional and social processing and the role of neural plasticity. In this Review, we discuss the ways in which these two different theories reflect different or complementary approaches, and how they might be integrated to offer novel solutions for people with depression. We consider the predictions made by these mechanistic approaches for the stratification and development of new therapeutics for depression, and the next steps that need to be made to facilitate this translation of science to the clinic.

    Although the symptoms of major depressive disorder (MDD) are often manageable with pharmacotherapy, response to first-line antidepressant treatment is often less than optimal. This study describes long-term treatment patterns in MDD patients in the United States and quantifies the economic burden associated with different treatment patterns following first-line antidepressant therapy. MDD patients starting first-line antidepressant monotherapy and having continuous enrollment ≥12 months before and ≥24 months following the index date (i.e., the first documented prescription fill) were selected from the Truven Health Analytics MarketScan (2003-2014) database. Based on the type of first treatment change following initiation, six treatment cohorts were defined a priori ("persistence"; "discontinuation"; "switch"; "dose escalation"; "augmentation"; and "combination"). Treatment patterns through the fourth line of therapy within each cohort, healthcare resource utilization (HCRU), and cost analyses were restricted to patients with adequate treatment duration (defined as ≥42 days) in each line (analysis sub-sample, N = 21,088). HCRU and costs were described at the cohort and pattern levels. Treatment cohorts representing patterns. Median time to discontinuation was 23 weeks. The switch cohort exhibited the highest HCRU (18.9 days with medical visits per-patient-per-year) and greatest healthcare costs ($11,107 per-patient-per-year) following the index date. Treatment patterns representing a cycling on and off treatment in the switch cohort were associated with the greatest healthcare costs overall. A high proportion of patients discontinue first-line antidepressant shortly after initiation. Patterns representing a cycling on and off treatment in the switch cohort were associated with the highest healthcare costs. These findings underscore challenges in effectively treating patients with MDD and a need for personalized patient management.

    The death of a person is a stressful event. Such stress affects the physical and psychological well-being of the bereaved. As an associated mental disorder, major depressive disorder (MDD) is common. Some dream of the deceased, and these dreams are called bereavement dreams. Some MDD patients also experience dreams. These two types of dreams are sometimes difficult to differentiate. The dream of the bereaved might be only a bereavement-related dream, yet it might be a symptom of MDD. Herein, we report one patient who had distressing dreams after the death of her mother. A 63-year-old woman was referred for psychiatric consultation because of generalized fatigue and insomnia. Questioning her about recent events, she said that her mother had died of colonic carcinoma 5 months previously. Two months after the death, she suddenly started dreaming of her mother, getting angry with her almost every night. Generalized fatigue, insomnia, and distressing dreams appeared simultaneously. The dream caused much distress, making her afraid to fall asleep. Her psychiatric features fulfilled the DSM-IV-TR criteria for MDD, single episode. The death of her mother was considered to be one of the causes of MDD. She was administered 25 mg/day of sertraline hydrochloride. After that, her symptoms gradually disappeared, and the frequency of distressing dreams was reduced. Five months later, physical and psychiatric symptoms of MDD were completely resolved. Subsequently, she has not suffered from any distressing dreams of her mother. This case indicates that dreams experienced after the death of a loved one should not be regarded simply as bereavement dreams. Some of the dreams may be symptoms of MDD. If the dreams are the symptoms of MDD, antidepressant treatment as well as psychotherapy may be useful. Therefore, we should avoid regarding symptoms of MDD as reactions to bereavement.

    Full Text Available Vanillin is a flavoring agent widely used in food and beverages such as chocolates and dairy products and it is also used to mask unpleasant tastes in medicine. It has been reported to have antioxidant, anti-inflammatory and antiapoptotic properties. The current study was designed to investigate the protective effects of vanillin against experimentally induced stress in rats. Briefly rats were subdivided into four groups. Three groups were subjected to chronic mild stress and the fourth group served as normal control group. One week before induction of stress drugs or saline was administered daily and continued for another nine weeks. At the end of the experimental period behavioral tests including sucrose preference test, forced swim test and elevated plus maze test were assessed. In addition, brain biochemical parameters including MDA, GSH, NO and serotonin were determined. Vanillin succeeded to restore the behavioral and biochemical changes associated with stress. It significantly increased sucrose consumption in sucrose preference test and time spent in open arm in elevated plus maze test as compared to stress control group. It also reduced immobility time in forced swim test and time spent in closed arm in elevated plus maze test. Additionally, it significantly decreased brain MDA and NO levels and significantly increased brain GSH and Serotonin levels compared to stress control group. It could be concluded that vanillin showed beneficial protective effects against experimentally induced stress in rats.

    Full Text Available The aim of the present study was to investigate the antidepressant-like effects of two fractions, including petroleum ether soluble fraction (Fraction A, FA and water-EtOH soluble fraction (Fraction B, FB prepared from the Danzhi-xiaoyao-san (DZXYS by using chronic unpredictable mild stress-induced depressive rat model. The results indicated that DZXYS could ameliorate the depression-like behavior in chronic stress model of rats. The inhibition of hyperactivity of HPA axis and the modulation of monoamine and amino acid neurotransmitters in the hippocampus may be the important mechanisms underlying the action of DZXYS antidepressant-like effect in chronically stressed rats.

    A number of studies implicate neuroplasticity in the therapeutic mechanisms of antidepressants, specifically neuroplasticity in the dentate gyrus of the hippocampal formation. The dorsal hippocampal region in rodents is preferentially involved in spatial learning and memory, while the ventral hippocampal region plays a more important role in stress, emotion, and affective behaviors. These findings led us to investigate behavioral changes and gene expression changes in the ventral and dorsal dentate gyrus differentially after chronic treatment in mice with the antidepressant sertraline. Four-week treatment with sertraline significantly decreased immobility in the modified forced swim test, a behavioral test for assessing antidepressant-like effects in rodents. In the novelty-suppressed feeding test, performance of which is affected by functional changes in the dentate gyrus, sertraline treatment significantly decreased latency to feed. Next, we examined the expression of several neuroplasticity-related genes (those for Notch receptors, basic helix-loop-helix transcription factors and related factors, SoxC transcription factors, and glial-related genes) by real-time RT-PCR in the ventral and dorsal dentate gyrus of mice after the sertraline treatment. The gene encoding the neuropeptide galanin was significantly induced in only ventral dentate gyrus, not in dorsal dentate gyrus. These results suggest that sertraline-related galanin induction in ventral dentate gyrus may play an important role in therapeutic mechanisms for depression. Copyright © 2013 Elsevier B.V.

    Reports of beneficial effects of exercise on psychological health in humans are increasingly supported by basic research studies. Exercise is hypothesized to regulate antidepressant-related mechanisms and we therefore characterized the effects of chronic exercise in mouse behavioral paradigms relevant to antidepressant actions. Mice given free access to running wheels showed antidepressant-like behavior in learned helplessness, forced-swim (FST) and tail suspension paradigms. These responses were similar to responses of antidepressant drug-treated animals. When tested under conditions where locomotor activity was not altered, exercising mice also showed reduced anxiety compared to sedentary control mice. In situ hybridization analysis showed that BDNF mRNA was increased in specific subfields of hippocampus after wheel running. We chose one paradigm, the FST, in which to investigate a functional role for brain-derived neurotrophic factor (BDNF) in the behavioral response to exercise. We tested mice heterozygous for a deletion of the BDNF gene in the FST after wheel-running. Exercising wild-type mice showed the expected antidepressant-like behavioral response in the FST but exercise was ineffective in improving FST performance in heterozygous BDNF knockout mice. A possible functional contribution of a BDNF signaling pathway to FST performance in exercising mice was investigated using the specific MEK inhibitor PD184161 to block the MAPK signaling pathway. Subchronic administration of PD184161 to exercising mice blocked the antidepressant-like behavioral response seen in vehicle-treated exercising mice in the FST. In summary, chronic wheel-running exercise in mice results in antidepressant-like behavioral changes that may involve a BDNF related mechanism similar to that hypothesized for antidepressant drug treatment.

    Chronic pain is a large and growing public health concern in Australia. Chronic pain is generally associated with physical, psychological, social and cultural risk factors. Several antidepressants have been efficacious in the management of chronic pain. This article illustrates the use of antidepressants in major chronic neuropathic pain conditions. Knowledge of psychopharmacology is important in the management of chronic pain. The majority of patients with chronic pain have comorbid psychiatric conditions ranging from mild anxiety, depression and adjustment problems, to severe delusional and psychotic disorders. Depression and anxiety are known to enhance the perception of pain. Not all antidepressants have independent analgesic properties. There is now a convincing body of controlled data, as well as extensive longstanding clinical experience, supporting tricyclic antidepressants (TCAs) as analgesics independently of their antidepressant actions.

    Resveratrol is a natural polyphenol enriched in Polygonum cuspidatum and has diverse biological activities. There is only limited information about the antidepressant-like effect of resveratrol. The present study assessed whether resveratrol treatment (20, 40 and 80mg/kg, i.p., 21days) has an antidepressant-like effect on the forced swim test (FST) and tail suspension test (TST) in mice and examined what its molecular targets might be. The results showed that resveratrol administration produced antidepressant-like effects in mice, evidenced by the reduced immobility time in the FST and TST, while it had no effect on the locomotor activity in the open field test. Resveratrol treatment significantly reduced serum corticosterone levels, which had been elevated by the FST and TST. Moreover, resveratrol increased brain-derived neurotrophic factor (BDNF) protein and extracellular signal-regulated kinase (ERK) phosphorylation levels in the prefrontal cortex and hippocampus. All of these antidepressant-like effects of resveratrol were essentially similar to those observed with the clinical antidepressant, fluoxetine. These results suggest that the antidepressant-like effects of resveratrol in the FST and TST are mediated, at least in part, by modulating hypothalamic-pituitary-adrenal axis, BDNF and ERK phosphorylation expression in the brain region of mice.

    Functional magnetic resonance imaging was used during emotion recognition to identify changes in functional brain activation in 21 first-episode, treatment-naive major depressive disorder patients before and after antidepressant treatment. Following escitalopram oxalate treatment, patients exhibited decreased activation in bilateral precentral gyrus, bilateral middle frontal gyrus, left middle temporal gyrus, bilateral postcentral gyrus, left cingulate and right parahippocampal gyrus, and increased activation in right superior frontal gyrus, bilateral superior parietal lobule and left occipital gyrus during sad facial expression recognition. After antidepressant treatment, patients also exhibited decreased activation in the bilateral middle frontal gyrus, bilateral cingulate and right parahippocampal gyrus, and increased activation in the right inferior frontal gyrus, left fusiform gyrus and right precuneus during happy facial expression recognition. Our experimental findings indicate that the limbic-cortical network might be a key target region for antidepressant treatment in major depressive disorder.

    Neurotrophins and glucocorticoids are robust synaptic modifiers, and deregulation of their activities is a risk factor for developing stress-related disorders. Low levels of brain-derived neurotrophic factor (BDNF) increase the desensitization of glucocorticoid receptors (GR) and vulnerability to stress, whereas higher levels of BDNF facilitate GR-mediated signaling and the response to antidepressants. However, the molecular mechanism underlying neurotrophic-priming of GR function is poorly understood. Here we provide evidence that activation of a TrkB-MAPK pathway, when paired with the deactivation of a GR-protein phosphatase 5 pathway, resulted in sustained GR phosphorylation at BDNF-sensitive sites that is essential for the transcription of neuronal plasticity genes. Genetic strategies that disrupted GR phosphorylation or TrkB signaling in vivo impaired the neuroplasticity to chronic stress and the effects of the antidepressant fluoxetine. Our findings reveal that the coordinated actions of BDNF and glucocorticoids promote neuronal plasticity and that disruption in either pathway could set the stage for the development of stress-induced psychiatric diseases.

    Full Text Available Background: It has been suggested, although not proven, that presence of concomitant psychiatric disorders may increase the inpatient costs for patients undergoing elective surgery. This study was designed to test the hypothesis that elective lumbar fusion surgery is more costly in patients with under treatment for depression. Methods: This is a retrospective case-control study of 142 patients who underwent elective lumbar fusion. Of those 142 patients, 41 patients were chronically using an antidepressant medication that considered as a "study group", and 101 patients were not taking an antidepressant medication that considered as a "control group". Data was collected for this cohort regarding antidepressant usage patient demographics, length of stay (LOS, age-adjusted Charlson comorbidity index scores and cost. Costs were compared between those with a concomitant antidepressant usage and those without antidepressant usage using multivariate analysis. Results: Patients using antidepressants and those with no history of antidepressant usage were similar in terms of gender, age and number of operative levels. The LOS demonstrated a non-significant trend towards longer stays in those using anti-depressants. Total charges, payments, variable costs and fixed costs were all higher in the antidepressant group but none of the differences reached statistical significance. Using Total Charges as the dependent variable, gender and having psychiatric comorbidities were retained independent variables. Use of an antidepressant was independently predictive of a 36% increase in Total Charges . Antidepressant usage as an independent variable also conferred a 22% increase in cost and predictive of a 19% increase in Fixed Cost . Male gender was predictive of a 30% increase in Total Charges . Conclusion: This study suggests use of antidepressant in patients who undergo elective spine fusion compared with control group is associated with increasing total cost and

  7. Peripheral administration of lactate produces antidepressant-like effects

    In addition to its role as metabolic substrate that can sustain neuronal function and viability, emerging evidence supports a role for l-lactate as an intercellular signaling molecule involved in synaptic plasticity. Clinical and basic research studies have shown that major depression and chronic stress are associated with alterations in structural and functional plasticity. These findings led us to investigate the role of l-lactate as a potential novel antidepressant. Here we show that peripheral administration of l-lactate produces antidepressant-like effects in different animal models of depression that respond to acute and chronic antidepressant treatment. The antidepressant-like effects of l-lactate are associated with increases in hippocampal lactate levels and with changes in the expression of target genes involved in serotonin receptor trafficking, astrocyte functions, neurogenesis, nitric oxide synthesis and cAMP signaling. Further elucidation of the mechanisms underlying the antidepressant effects of l-lactate may help to identify novel therapeutic targets for the treatment of depression.

    Irritable bowel syndrome (IBS) is a functional disease with good prognosis, which is diagnosed by exclusion of possible causative organic diseases. However, since the patients tend to have strong psychotic symptoms including anxiety, tension, depression, irritation and insomnia, this syndrome has to be elucidated as a psychosomatic disease. Although the symptoms are usually limited to gastrointestinal symptoms such as abdominal pain and abnormal bowel movements, many patients also manifest some kinds of psychiatric abnormalities such as hypochondria, depression, hysteria, panic disorder and posttraumatic stress disorder. Especially, the prevalence of depression is high. Therefore, use of psychotropic drugs is efficient in treating IBS. Antidepressant agents including tricyclic agents such as amitriptyline, trimipramine, imipramine, clomipramine, amoxapine and nortriptyline; tetracyclic antidepressant; antidepressants such as SSRI and SNRI; sulpiride; benzodiazepine class anxiolytic agents; tandospirone; and Chinese herbal medicine are being used. IBS is a stress-related disease. Therefore, in spite of the importance of pharmacotherapy, patients should also be instructed to avoid the stress that aggravates the symptoms in all aspects of daily life.

    Developments increasing our understanding of chronic urticaria have resulted in the simplification and improvement of available treatments. Currently, many treatments target mast cell mediators, but we can now disrupt mast cell activation with the anti-IgE antibody omalizumab, which has markedly advanced the treatment landscape for patients with difficult-to-treat urticaria. Current guidelines provide a framework for the management and treatment of patients with CU but, as each patient is different, knowledge and experience of specialist dermatologists and allergists are key to effective pharmacotherapy. This article reviews the different therapeutic options for patients with chronic spontaneous urticaria (also called chronic idiopathic urticaria) or chronic inducible urticaria and discusses management of special populations or special circumstances related to CU.

  11. The Antidepressant Effect of Angelica sinensis Extracts on Chronic Unpredictable Mild Stress-Induced Depression Is Mediated via the Upregulation of the BDNF Signaling Pathway in Rats

    Full Text Available Angelica sinensis (AS, a traditional Chinese herbal medicine, has pharmaceutical effects on menstrual illness, cerebrovascular diseases, cardiovascular diseases, and cognitive impairments. However, until recently, few studies had explored its antidepressant effect. The current study attempts to investigate the effect of AS extracts on chronic unpredictable mild stress- (CUMS- induced depression in rats. Male SD rats were exposed to a CUMS-inducing procedure for 5 weeks, resulting in rodent depressive behaviors that included reduced sucrose consumption and lessened sucrose preference ratios in sucrose preference test, prolonged immobility times and decreased struggling time in force swim test, and decreased locomotor activity in open field test. Moreover, the expression of brain derived neurotrophic factor (BDNF and the phosphorylation of cAMP-response element binding protein (CREB and extracellular signal-regulated protein kinase (ERK 1/2 were markedly decreased in the hippocampus in depressed rats. However, chronically treating the depressed rats with AS (1 g/kg normalized their depression-related behaviors and molecular profiles. In conclusion, in the present study, we show that AS extracts exerted antidepressant effects that were mediated by the BDNF signaling pathway: in AS-treated depressed rats, the expression of the BDNF protein and the phosphorylation of its downstream targets (ERK 1/2, CREB were upregulated in the hippocampus.

  13. The mechanism of action of antidepressants revised.

    1990-01-01

    The discovery of the clinical efficacy of imipramine and of the MAO-inhibitor iproniazid intensively stimulated biochemical-pharmacological research on the mechanism of action of antidepressants. Due to these investigations, until recently an enhanced activity of the central noradrenergic and/or serotonergic transmitter system was considered essential for the clinical antidepressive action. Such enhancement could be achieved either presynaptically by blocking alpha 2-adrenergic receptors, or in the synaptic cleft by inhibiting the transmitter reuptake or the main metabolic enzyme, MAO. The common final result, especially of chronic treatment, was the down-regulation of postsynaptic beta-receptors, modulated by interaction with the serotonergic system, neuropeptides, and hormones. The delay of clinical response corresponded better with such receptor alterations. However, the introduction of new, more selective antidepressants led to new reflections upon the mechanism of action. On the level of transmitters, alpha 1-upregulation, increased activity of the dopaminergic system, an alteration in the balance between the different transmitter systems, are reported and seem to be important. Most promising are recent investigations of the second messenger systems, the adenylate cyclase system and the phosphatidylinositol system. Both systems are modulated by antidepressant drugs including lithium and carbamazepine. These second messengers, in turn, modulate the phosphorylation status of neuronal proteins via protein kinase, which may lead to elevations of the above mentioned receptors and again their transduction systems.

    What are the benefits and harms of second generation antidepressants and cognitive behavioral therapies (CBTs) in the initial treatment of a current episode of major depressive disorder in adults? This was a systematic review including qualitative assessment and meta-analyses using random and fixed effects models. Medline, Embase, the Cochrane Library, the Allied and Complementary Medicine Database, PsycINFO, and the Cumulative Index to Nursing and Allied Health Literature were searched from January 1990 through January 2015. The 11 randomized controlled trials included compared a second generation antidepressant CBT. Ten trials compared antidepressant monotherapy with CBT alone; three compared antidepressant monotherapy with antidepressant plus CBT. Meta-analyses found no statistically significant difference in effectiveness between second generation antidepressants and CBT for response (risk ratio 0.91, 0.77 to 1.07), remission (0.98, 0.73 to 1.32), or change in 17 item Hamilton Rating Scale for Depression score (weighted mean difference, -0.38, -2.87 to 2.10). Similarly, no significant differences were found in rates of overall study discontinuation (risk ratio 0.90, 0.49 to 1.65) or discontinuation attributable to lack of efficacy (0.40, 0.05 to 2.91). Although more patients treated with a second generation antidepressant than receiving CBT withdrew from studies because of adverse events, the difference was not statistically significant (risk ratio 3.29, 0.42 to 25.72). No conclusions could be drawn about other outcomes because of lack of evidence. Results should be interpreted cautiously given the low strength of evidence for most outcomes. The scope of this review was limited to trials that enrolled adult patients with major depressive disorder and compared a second generation antidepressant with CBT, and many of the included trials had methodological shortcomings that may limit confidence in some of the findings.

    Computers and related technology can increase the amount of treatment received by adults with chronic aphasia. Computers used in treatment, however, are only valuable to the patient if the intervention is efficacious. Real and potential applications of computer technology are discussed in the context of three roles of computerized aphasia treatment for adults with chronic aphasia. Pertinent studies regarding Phases 1 and 2 are briefly described. The only Phase 3 study of efficacy of computerized aphasia treatment is more fully described and its implications discussed.

    Full Text Available Standart antidepressants are needed for the many individuals with major depressive disorder. However they do not respond adequately to treatment and because of a delay of weeks before the emergence of therapeutic effects. Recent studies show that subanesthetic dose of ketamine is efficacy and safety for the treatment of depression. Antidepressant effects of ketamine have been found to be short-lived and its psychotomimetic properties may limit the use of ketamine to depressive patients. Future research studies should focus on identifying predictors of response (pharmalogical and clinical , investigating application of different doses and routes of administration and maintaining antidepressant effect.

    The changes of gene expression resulting from long-term exposure to monoamine antidepressant drugs in experimental animals are key to understanding the mechanisms of action of this class of drugs in man. Many of these genes and their products are either relevant biomarkers or directly involved in structural changes that are perhaps necessary for the antidepressant effect. Tesofensine is a novel triple monoamine reuptake inhibitor that acts to increase noradrenaline, serotonin, and dopamine neurotransmission. This study was undertaken to examine the effect of sub-chronic (5 days) and chronic (14 days) administration of Tesofensine on the expression of brain derived neurotrophic factor (BDNF) and activity-regulated cytoskeleton protein (Arc) in the rat hippocampus. Furthermore, hippocampi from the same animals were used to investigate the effect on cell proliferation by means of Ki-67- and NeuroD-immunoreactivity. We find that chronic, but not sub-chronic treatment with Tesofensine increases BDNF mRNA in the CA3 region of the hippocampus (35%), and Arc mRNA in the CA1 of the hippocampus (65%). Furthermore, the number of Ki-67- and neuroD-positive cells increased after chronic, but not sub-chronic treatment. This study shows that Tesofensine enhances hippocampal gene expression and new cell formation indicative for an antidepressant potential of this novel drug substance.

  4. The importance of new antidepressants in the treatment of anxiety/depressive disorders.

    Patients suffering from anxiety and depression are often seen in clinical practice. In accordance with the diagnostic criteria of DSM-III/IV and ICD-10, respectively, there may be various combinations of symptoms and degrees of severity. The symptoms of these patients may range from subthreshold anxiety or depression to a combination of anxiety and depressive disorders. Besides giving an extensive survey of diagnostic problems and the epidemiological incidence of such combinations, pharmacotherapeutic approaches are critically reviewed. Metaanalyses have shown that various serotonin reuptake inhibitors (SSRI) are equivalent, if not superior, to tricyclic antidepressants (TCA) in their anti-anxiety effectiveness. Hence, SSRI may be considered a therapy of choice, not least on account of very few adverse effects and good tolerance. More recent antidepressants are under scrutiny for their anti-anxiety efficacy. Citalopram, venlafaxine and, because of its established sedative action, nefazodone seem to be particularly suited to fill a possible therapeutic gap and to provide agitated patients with an alternative to TCA.

  5. Assessing substrates underlying the behavioral effects of antidepressants using the modified rat forced swimming test.

    Cryan, John F; Valentino, Rita J; Lucki, Irwin

    2005-01-01

    Selective serotonin reuptake inhibitors (SSRIs) are the most widely prescribed antidepressant class today and exert their antidepressant-like effects by increasing synaptic concentrations of serotonin (5-HT). The rat forced swim test (FST) is the most widely used animal test predictive of antidepressant action. Procedural modifications recently introduced by our laboratory have enabled SSRI-induced behavioral responses to be measured in the modified FST. The use of this model to understand the pharmacological and physiological mechanisms underlying the role of 5-HT in the behavioral effects of antidepressant drugs is reviewed. Although all antidepressants reduced behavioral immobility, those antidepressants that increase serotonergic neurotransmission predominantly increase swimming behavior whereas those that increase catacholaminergic neurotransmission increase climbing behavior. The 5-HT(1A), 5-HT(1B/1D) and 5-HT(2C) receptors are the 5-HT receptors most important to the therapeutic effects of SSRIs, based on extensive evaluation of agonists and antagonists of individual 5-HT receptor subtypes. Studies involving chronic administration have shown that the effects of antidepressants are augmented following chronic treatment. Other studies have demonstrated strain differences in the response to serotonergic compounds. Finally, a physiological model of performance in the rat FST has been proposed involving the regulation of 5-HT transmission by corticotropin releasing factor (CRF).

    2010-07-01

    The aim of the study was to examine whether the reduction of theta prefrontal quantitative EEG (QEEG) cordance after one week of bupropion administration is a predictor of response to a 4-week treatment in patients that had failed to respond to previous antidepressant treatments. EEG data of 18 inpatients were monitored at baseline and after one week. QEEG cordance was computed at 3 frontal electrodes (Fp1, Fp2, Fz). Response to treatment was defined as a >/=50% reduction of MADRS score. Nine of the eleven responders and one of the seven non-responders showed decreased prefrontal cordance value after the first week of treatment (p=0.01). Positive and negative predictive values of cordance reduction for the prediction of response to the treatment were 0.9 and 0.75, respectively. Similar to other antidepressants, the reduction of prefrontal QEEG cordance might be helpful in the prediction of the acute outcome of bupropion treatment. Copyright 2010 Elsevier B.V. and ECNP.

    2017-07-15

    Despite over a half-century's intensive research worldwide, the currently available antidepressants remain sub-optimal. Therapeutic options for treatment-resistant depression, for instance, are rather limited. Here, we found that rats exhibited a lasting treatment-resistant depressive immobility in response to open space swim test at a high intensity of induction. The induced depressive behavior is associated with a dramatic impairment in spatial learning and memory. Both the depressive immobility and impairment in spatial learning and memory are sensitive to a period of chronic treatment with bryopstatin-1, a relatively selective activator of protein kinase Cε. Bryostatin-1-like analogues therefore might have therapeutic values for the treatment of treatment-resistant depression. Copyright © 2017 Elsevier B.V. All rights reserved.

The use of regional anesthesia conducted by anesthesiologists in pain clinics demonstrated the evidence based efficacy of different types of peridural injections of local anesthetics with steroids in patients with root pain syndromes at cervical and lumbar levels. Therapeutic blockades of the occipital nerve is effective method of treatment of cervicogenic and cluster headache as well as occipital nerve neuralgia. There are clear indications of the efficacy of local injections in primary chronic cephalgia (migraine and headache of tension). The possibility of the abortion of the pain information flow in peripheral nociceptive pathways and, as a consequence, breaking the vicious circle is emphasized. Issues on the efficacy of local injections at trigger points in the treatment of chronic pain are highlighted.

    Neuropathic pain arises as a consequence of a lesion or disease affecting the somatosensory system. It is generally chronic and challenging to treat. The recommended pharmacotherapy for neuropathic pain includes the use of some antidepressants, such as tricyclic antidepressants (TCAs) (amitriptyline…) or serotonin and noradrenaline re-uptake inhibitors (duloxetine…), and/or anticonvulsants such as the gabapentinoids gabapentin or pregabalin. Antidepressant drugs are not acute analgesics but require a chronic treatment to relieve neuropathic pain, which suggests the recruitment of secondary downstream mechanisms as well as long-term molecular and neuronal plasticity. Noradrenaline is a major actor for the action of antidepressant drugs in a neuropathic pain context. Mechanistic hypotheses have implied the recruitment of noradrenergic descending pathways as well as the peripheral recruitment of noradrenaline from sympathetic fibers sprouting into dorsal root ganglia; and importance of both α2 and β2 adrenoceptors have been reported. These monoamine re-uptake inhibitors may also indirectly act as anti-proinflammatory cytokine drugs; and their therapeutic action requires the opioid system, particularly the mu (MOP) and/or delta (DOP) opioid receptors. Gabapentinoids, which target the voltage-dependent calcium channels α2δ-1 subunit, inhibit calcium currents, thus decreasing the excitatory transmitter release and spinal sensitization. Gabapentinoids also activate the descending noradrenergic pain inhibitory system coupled to spinal α2 adrenoceptors. Gabapentinoid treatment may also indirectly impact on neuroimmune actors, like proinflammatory cytokines. These drugs are effective against neuropathic pain both with acute administration at high dose and with repeated administration. This review focuses on mechanistic knowledge concerning chronic antidepressant treatment and gabapentinoid treatment in a neuropathic pain context. Copyright © 2016 IBRO. Published by

  13. Preferential reduction of binding of sup 125 I-iodopindolol to beta-1 adrenoceptors in the amygdala of rat after antidepressant treatments

    1991-05-01

    This study utilized quantitative receptor autoradiography to examine the effects of repeated administration of antidepressants to rats on the binding of the beta adrenoceptor antagonist, {sup 125}I-iodopindolol ({sup 125}I-IPIN) to either beta-1 or beta-2 adrenoceptors in various regions of brain. Antidepressants were selected to represent various chemical and pharmacological classes including tricyclic compounds (desipramine and protriptyline), monoamine oxidase inhibitors (clorgyline, phenelzine and tranylcypromine), atypical antidepressants (mianserin and trazodone) and selective inhibitors of the uptake of serotonin (citalopram and sertraline). Additionally, rats were treated with various psychotropic drugs that lack antidepressant efficacy (cocaine, deprenyl, diazepam and haloperidol). Repeated treatment of rats with desipramine, protriptyline, clorgyline, phenelzine, tranylcypromine or mianserin reduced the binding of {sup 125}I-IPIN to beta-1 adrenoceptors in many brain areas. Only in the basolateral and lateral nuclei of the amygdala did all six of these antidepressants significantly reduce {sup 125}I-IPIN binding to beta-1 adrenoceptors. In these amygdaloid nuclei, the magnitude of the reduction in the binding of {sup 125}I-IPIN caused by each of these drugs was comparable to or greater than the reduction in binding produced in any other region of brain. Reductions of binding of {sup 125}I-IPIN after antidepressant treatments were not consistently observed in the cortex, the area of brain examined most often in homogenate binding studies. Only the monoamine oxidase inhibitors caused reductions in the binding of {sup 125}I-IPIN to beta-2 adrenoceptors, and this effect was generally localized to the amygdala and hypothalamus.

    Seasonal changes in the concentration of 21 pharmaceuticals in a wastewater treatment plant (WWTP) in České Budějovice were investigated over 12months. The target compounds were 10 antibiotics, 4 antidepressants, 3 psychiatric drugs, 2 antihistamines and 2 lipid regulators. 272 Wastewater samples (136 influents and 136 effluents) were collected from March 2011 to February 2012 and analyzed using two-dimensional liquid chromatography coupled with tandem mass spectrometry. All studied pharmaceuticals were frequently detected in both the influent and the effluent wastewater samples, except for meclozine, which was only found in the influent. The mean concentration of pharmaceuticals varied from 0.006μgL(-1) to 1.48μgL(-1) in the influent and from 0.003μgL(-1) to 0.93μgL(-1) in the effluent. The concentration of most pharmaceuticals was higher during winter.

    2014-06-01

    Chronic spontaneous urticaria, also known as chronic idiopathic urticaria or simply chronic urticaria, is a common disorder that has a prevalence in the general population that ranges between 0.5% and 1%. This condition negatively affects the patient's quality of life and has considerable impact on direct and indirect health-related costs. Chronic urticaria is difficult to manage. Nonsedating H1 antihistamines are the first line of therapy, but fewer than 50% of patients experience relief at recommended dosages. Although guidelines call for increasing the dosage when response is inadequate, some patients still do not achieve adequate control of symptoms. New treatment alternatives, with proven efficacy under the standards of evidence-based medical practice, must therefore be developed.

    Reduced promoter IV-driven expression of brain-derived neurotrophic factor (BDNF) is implicated in stress and major depression. We previously reported that defective promoter IV (KIV) caused depression-like behavior in young adult mice, which was reversed more effectively by enriched environment treatment (EET) than antidepressants. The effects of promoter IV-BDNF deficiency and EET over the life stages remain unknown. Since early-life development (ED) involves dynamic epigenetic processes, we hypothesized that EET during ED would provide maximum antidepressive effects that would persist later in life due to enhanced, long-lasting BDNF induction. We tested this hypothesis by determining EET effects across three life stages: ED (0–2 months), young adult (2–4 months), and old adult (12–14 months). KIV mice at all life stages showed depression-like behavior in the open-field and tail-suspension tests compared with wild-type mice. Two months of EET reduced depression-like behavior in ED and young adult, but not old adult mice, with the largest effect in ED KIV mice. This effect lasted for 1 month after discontinuance of EET only in ED mice. BDNF protein induction by EET in the hippocampus and frontal cortex was also the largest in ED mice and persisted only in the hippocampus of ED KIV mice after discontinuance of EET. No gender-specific effects were observed. The results suggest that defective promoter IV causes depression-like behavior, regardless of age and gender, and that EET during ED is particularly beneficial to individuals with promoter IV-BDNF deficiency, while additional treatment may be needed for older adults.

However, the major advance is up to now restricted to genotype 1 (GT-1 patients. The development of second-wave and second-generation PIs yields higher antiviral potency through plurigenotypic activity, more convenient daily administration, fewer side effects and, for the second-generation PIs, potential activity against resistance-associated variants. NS5B inhibitors include nucleoside/nucleotide inhibitors (NIs and non-nucleotide inhibitors (NNIs. NIs have high efficacy across all genotypes. Sofosbuvir has highly potent antiviral activity across all genotypes in association with pegylated interferon and ribavirin (PR, thus allowing shortened treatment duration. NS5A inhibitors (NS5A.I have highly potent antiviral activity. It has recently been shown for the first time that NS5A.I in combination with protease inhibitors can cure GT-1b null responders in an interferon-free regimen. Besides, several studies demonstrate that interferon (IFN-free regimens with direct-acting antiviral agent combinations are able to cure a large number of either naïve or treatment-experienced GT-1 patients. Moreover, quadruple regimen with PR is able to cure almost all GT-1 null responders. The development of pan-genotypic direct-acting antiviral agents (NIs or NS5A.I allows new combinations with or without PR that increase the rate of sustained virological response for all patients, even for those with cirrhosis and independently of the genotype. Therefore, the near future of HCV treatment looks promising. The purpose of this article is to provide an overview of the clinical results recently reported for HCV treatment.Keywords: SVR, direct antiviral agents, host

    Switching antidepressant medication may be helpful in depressed patients having no benefit from the initial antidepressant treatment. Before considering switching strategy, the initial antidepressant treatment should produce no therapeutic effect after at least 4 weeks of administration at adequate dosage. Choosing an antidepressant of pharmacologically distinct profile fails to consistently demonstrate a significant superiority in terms of effectiveness over the switching to another antidepressant within the same pharmacological class. Augmenting SSRI/SNRIs with mirtazapine/mianserin has become the most recommended strategy of antidepressant combinations. Augmenting SSRI with tricyclic drugs is now a less recommended strategy of antidepressant combinations given the increased risk for the occurrence of pharmacokinetic drug-drug interactions and adverse effects.

    Chronic constipation is highly prevalent, reduces patients' quality of life, and imposes a significant health care burden on society. Lifestyle modifications and over-the-counter agents improve symptoms of constipation in some patients, however many patients have persistent symptoms and require the use of prescription medications. Three prescription medications are currently Food and Drug Administration (FDA) approved and available for the treatment of chronic constipation in adults. This review will focus on lubiprostone, the newest medication available for the treatment of chronic constipation. Lubiprostone is a bicyclic fatty acid metabolite analogue ofprostaglandin E1. It activates specific chloride channels in the gastrointestinal tract to stimulate intestinal fluid secretion, increase gastrointestinal transit, and improve symptoms of constipation. This article will provide a brief overview on chloride channel function in the gastrointestinal tract, describe the structure, function, and pharmacokinetics of lubiprostone, and discuss the safety and efficacy of this new medication.

    We analyzed the results of treatment of 432 patients with chronic hemorrhoids using different variants of latex ligation. New technique including ligation of mucosa and submucosa of low-ampullar rectum providing ligation of hemorrhoidalvessels, lifting and recto-anal repair is developed and suggested. This method is advisable to use in case of chronic internal hemorrhoids stages I and II. The authors recommend simultaneous combined ligation of mucosa of low-ampullar rectum and internal hemorrhoids for stages III and IV. Different variants of latex ligation with external hemorrhoids excision were used in 103 patients. Pointed variants of latex ligation preserve important advantages including mini-invasiveness, simplicity and wide availability, low cost. Good remote results were obtained after these procedures in 87.3% of observations. Suggested tactics extends use of latex ligation and increases its effectiveness in treatment of different stages and forms of chronic hemorrhoids.

    Abscisic acid (ABA), a crucial phytohormone, is distributed in the brains of mammals and has been shown to have antidepressant effects in the chronic unpredictable mild stress test. The forced swim test (FST) is another animal model that can be used to assess antidepressant-like behavior in rodents. Here, we report that the antidepressant effects of ABA are associated with sensitivities to the FST in mice. Based on mean immobility in the 5-min forced swim pre-test, ICR mice were divided into short immobility mice (SIM) and long immobility mice (LIM) substrains. FST was carried out 8 days after drug administration. Learned helplessness, as shown by increased immobility, was only observed in SIM substrain and could be prevented by an 8-day ABA treatment. Our results show that ABA has antidepressant effects in SIM substrain and suggest that mice with learned helplessness might be more suitable for screening potential antidepressant drugs.

    Depression is the leading psychiatric disorder with a high risk of morbidity and mortality. Clinical studies report lower serum zinc in depressed patients, suggesting a strong link between zinc and mood disorders. Also copper as an antagonistic element to zinc seems to play a role in depression, where elevated concentration is observed. In the present study we investigated serum copper and zinc concentration after acute or chronic antidepressant (AD) treatment under pathological/zinc-deficient conditions. Zinc deficiency in mice was induced by a special diet administered for 6 weeks (zinc adequate diet - ZnA, contains 33.5 mgZn/kg; zinc deficient diet - ZnD, contains 0.2 mgZn/kg). Animals received acute or chronically saline (control), imipramine, escitalopram, reboxetine or bupropion. To evaluate changes in serum copper and zinc concentrations the total reflection X-ray fluorescence (TXRF) and flame atomic absorption spectrometry (FAAS) was performed. In ZnD animals serum zinc level was reduced after acute ADs treatment (similarly to vehicle treatment), however, as demonstrated in the previous study after chronic ADs administration no differences between both ZnA and ZnD groups were observed. Acute ADs in ZnD animals caused different changes in serum copper concentration with no changes after chronic ADs treatment. The calculated serum Zn/Cu ratio is reduced in ZnD animals (compared to ZnA subjects) treated with saline (acutely or chronically) and in animals treated acutely with ADs. However, chronic treatment with ADs normalized (by escitalopram, reboxetine or bupropion) or increased (by imipramine) this Zn/Cu ratio. Observed in this study normalization of serum Zn/Cu ratio in depression-like conditions by chronic (but not acute) antidepressants suggest that this ratio may be consider as a marker of depression or treatment efficacy.

    Full Text Available Background and Objectives: The aim of the study was to examine the antidepressant effect of a single pulse dose of intravenous clomipramine (200 mg i.v. followed by oral administration as an alternative method to electroconvulsive therapy. Methods: Twenty-one inpatients (8 male, 13 female with major depression were included. Depression severity was measured by Montgomery Asberg Rating Scale (MADRS and Clinical Global Impression severity scale (CGI-S before the pulse dose and 1 week after. The day after the pulse dose, the patient was medicated with 75 mg of oral clomipramine and from day two with 150 mg clomipramine daily. Results: The MADRS score dropped with 39% ± 22% and the CGI score with 28% ± 19% in one week. The improvement of the MADRS score after one week was 13.1 (C.I.9.5-17.0. CGI-ratings dropped from a mean of 5.5 (SD 1.2 to 3.9 (SD 1.1, an improvement of 28% ± 19%.(C.I. 1.0-2.1. Both improvements were significant (p<000.1. Conclusions: Single pulse dose clomipramine administration ameliorates depressive symptoms, and may be an alternative to ECT.

    Major depressive disorder (MDD) is a prevalent and disabling psychiatric disease with rates of non-responsiveness to antidepressants ranging from 30–50%. Historically, the monoamine depletion hypothesis has dominated the view on the pathophysiology of depression. However, the lack of responsiveness to antidepressants and treatment resistance suggests that additional mechanisms might play a role. Evidence has shown that a subgroup of depressive patients may have an underlying immune deregulation that could explain the lack of therapeutic benefit from antidepressants. Stimuli like inflammation and infection can trigger the activation of microglia to release pro-inflammatory cytokines, acting on two main pathways: (1) activation of the hypothalamic–pituitary adrenal axis, generating an imbalance in the serotonergic and noradrenergic circuits; (2) increased activity of the enzyme indoleamine-2,3-dioxygenase, resulting in depletion of serotonin levels and the production of quinolinic acid. If this hypothesis is proven true, the subgroup of MDD patients with increased levels of pro-inflammatory cytokines, mainly IL-6, TNF-α and IL-1β, might benefit from an anti-inflammatory intervention. Here, we discuss the pre-clinical and clinical studies that have provided support for treatment with non-steroidal anti-inflammatory drugs in depressed patients with inflammatory comorbidities or an elevated immune profile, as well as evidences for anti-inflammatory properties of standard antidepressants.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a sporadically occurring, acquired neuropathic condition of autoimmune origin with chronic progressive or relapsing-remitting disease course. CIDP is a treatable disorder; a variety of immunosuppressive and immunomodulatory agents are available to modify, impede, and even reverse the neurological deficits and sequelae that manifest in the course of the disease. However, in many cases CIDP is not curable. Challenges that remain in the treatment of CIDP patients are well recognized and include a remarkably individual heterogeneity in terms of disease course and treatment response as well as a lack of objective and feasible measures to predict and monitor the responsiveness to the available therapies. In this chapter an overview of the currently used drugs in the treatment of CIDP patients is given and some important and controversial issues that arise in the context of care for CIDP patients are discussed.

    Migraine is an episodic painful disorder occasionally developing into a chronic form. Such disorder represents one of the most common neurological diseases in clinical practice. Chronicization is often accompanied by the appearance of acute drugs overuse. Chronic migraine (CM) constitutes migraine's natural evolution in its chronic form and involves headache frequency of 15 days/month, with features similar to those of migraine attacks. Medication Overuse Headache (MOH) has been defined as a headache present on > or = 15 days/month, with regular overuse for > 3 months of one or more drugs used for acute and/or symptomatic headache management. Subtypes of MOH attributed to different medications were delineated. Misuse of ergots, triptans, opioids or combination analgesics on > or = 10 days/month was required to make the diagnosis of MOH, while > or = 15 days/month were needed for simple analgesic-overuse headache. CM's low prevalence produces an extremely high disability grade. Therefore, special attention should be paid to both control and reduction of risk factors which might favour the migraine chronicization process and/or the outbreak of MOH. In MOH sufferers, the only treatment of choice is represented by drug withdrawal. Successful detoxification is necessary to ensure improvement in the headache status when treating patients who overuse acute medications. Different procedures have been suggested for withdrawal namely at home, at the hospital, with or without the use of steroids, with re-prophylaxis performed immediately or at the end of the washout period. At the moment we have not a total agreement whether prophylactic treatment should be started before, during, or after discontinuation of the overuse drug. Both drugs have been approved for CM treatment in view of their well-defined resistance to previous prophylaxis drugs. Recently, the PREEMPT clinical program has confirmed onabotulinumtoxinA as an effective, safe, and well-tolerated prophylactic

    A growing body of evidence has pointed to the N-methyl-d-aspartate (NMDA) receptor antagonists as a potential therapeutic target for the treatment of major depression. The present study investigated the possibility of synergistic interactions between antidepressant imipramine with the uncompetitive NMDA receptor antagonist ketamine. Wistar rats were acutely treated with ketamine (5 and 10mg/kg) and imipramine (10 and 20mg/kg) and then subjected to forced swimming tests. The cAMP response element bindig (CREB) and brain-derived neurotrophic factor (BDNF) protein levels and protein kinase C (PKC) and protein kinase A (PKA) phosphorylation were assessed in the prefrontal cortex, hippocampus and amygdala by imunoblot. Imipramine at the dose of 10mg/kg and ketamine at the dose of 5mg/kg did not have effect on the immobility time; however, the effect of imipramine (10 and 20mg/kg) was enhanced by both doses of ketamine. Ketamine and imipramine alone or in combination at all doses tested did not modify locomotor activity. Combined treatment with ketamine and imipramine produced stronger increases of CREB and BDNF protein levels in the prefrontal cortex, hippocampus and amygdala, and PKA phosphorylation in the hippocampus and amygdala and PKC phosphorylation in prefrontal cortex. The results described indicate that co-administration of antidepressant imipramine with ketamine may induce a more pronounced antidepressant activity than treatment with each antidepressant alone. This finding may be of particular importance in the case of drug-resistant patients and could suggest a method of obtaining significant antidepressant actions whilst limiting side effects.

    Sildenafil is a highly effective oral agent for the treatment of erectile dysfunction of multiple etiologies. Although in clinical practice sildenafil is often used in depressed patients, its influence on the pathophysiology of depression remains unclear. The aim of the present study was to evaluate the antidepressant-like activity following acute and subchronic treatment with sildenafil in naïve mice as well as in mice with reserpine- and restraint stress-induced depressive-like behavior. Since corticosterone is released in response to acute stress, we also aimed to assess the influence of sildenafil on serum corticosterone level in non-stressed and stressed animals. The antidepressant activity of sildenafil was assessed in the forced swim test. Corticosterone serum level was determined by using ELISA method, while brain and serum sildenafil level via HPLC method. Sildenafil administered acutely exerted an antidepressant-like effect. Subchronic (14 days) administration of sildenafil resulted only in a weak antidepressant-like effect when evaluated 24 h after the last dose. Acute but not subchronic sildenafil administration reversed the reserpine- and stress-induced immobility in the forced swim test. The lack of effects of sildenafil after subchronic treatment could have been related to its complete elimination from the brain within 24 h from the last injection. Interestingly, acute administration of sildenafil produced a marked increase in serum corticosterone level in both non-stressed and stressed animals. Sildenafil exerts differential effects in the forced swim test after acute and subchronic administration. Further studies on the antidepressant activity of sildenafil are required.

    Background There is hardly evidence on maintenance treatment with antidepressants in primary care. Nevertheless, depression guidelines recommend maintenance treatment i.e. treatment to prevent recurrences, in patients with high risk of recurrence, and many patients use maintenance treatment with antidepressants. This study explores the characteristics of patients on maintenance treatment with antidepressants in general practice, and compares these characteristics with guideline recommendations for maintenance treatment. Methods We used data (baseline, two-year and four-year follow-up) of primary care respondents with remitted depressive disorder (≥6 months) from the Netherlands Study of Depression and Anxiety (n = 776). Maintenance treatment was defined as the use of an antidepressant for ≥12 months. Multilevel logistic regression was used to describe the association between sociodemographic, clinical and care characteristics and use of maintenance treatment with antidepressants. Results Older patients, patients with a lower education, those using benzodiazepines or receiving psychological/psychiatric care and patients with a concurrent history of a dysthymic or anxiety disorder more often received maintenance treatment with antidepressants. Limitations Measurements were not made at the start of an episode, but at predetermined points in time. Diagnoses were based on interview (CIDI) data and could therefore in some cases have been different from the GP diagnosis. Conclusions Since patients with chronic or recurrent depression do not use maintenance treatment with antidepressants more often, characteristics of patients on maintenance treatment do not fully correspond with guideline recommendations. However, patients on maintenance treatment appear to be those with more severe disorder and/or more comorbidity. PMID:24858011

    Recent rodent models of antidepressant response implicate a novel set of genes in mechanisms of antidepressant action. The authors examined variants in four such genes (KCNK2 (TREK1), SLC18A2 (VMAT2), S100A10, and HDAC5) for association with remission in a large effectiveness trial of antidepressant treatments. Subjects were drawn from the Sequenced Treatment Alternatives to Relieve Depression (STAR(*)D) study, a multicenter, prospective, effectiveness trial in major depressive disorder (MDD). Outpatients with nonpsychotic MDD were initially treated with citalopram for up to 14 weeks; those who did not remit with citalopram were sequentially randomized to a series of next-step treatments, each for up to 12 weeks. Single-nucleotide polymorphisms in four genes were examined for association with remission, defined as a clinician-rated Quick Inventory of Depressive Symptomatology (QIDS-C(16)) score < or =5. Of 1554 participants for whom DNA was available, 565 (36%) reached remission with citalopram treatment. No association with any of the four genes was identified. However, among the 751 who entered next-step treatment, variants in KCNK2 were associated with treatment response (Bonferroni-corrected, gene-based empirical p<0.001). In follow-up analyses, KCNK2 was also associated with effects of similar magnitude for third-step treatment among those with unsatisfactory benefit to both citalopram and one next-step pharmacotherapy (n=225). These findings indicate that genetic variation in KCNK2 may identify individuals at risk for treatment resistance. More broadly, they indicate the utility of animal models in identifying genes for pharmacogenetic studies of antidepressant response.

Here, we investigated the efficacy of aripiprazole augmentation for TRD including both major depressive disorder and bipolar disorder and the clinical predictors of treatment efficacy in a Japanese population.  Methods: Eighty-five depressed Japanese patients who underwent aripiprazole augmentation therapy after failing to respond satisfactorily to antidepressant monotherapy were included in the study. Treatment responses were evaluated based on Clinical Global Impression Improvement scores assessed 8 weeks after initiation of aripiprazole administration. We compared demographic and diagnostic variables, psychiatric medication variables, and clinical variables between remission and nonremission groups.  Results: The aripiprazole augmentation remission rate was 36.5%. Multiple logistic regression analysis indicated that aripiprazole augmentation was significantly more effective for bipolar depression than for major depressive disorder, and both absence of comorbid anxiety disorders and current episode duration >3 months were significantly associated with the efficacy of aripiprazole augmentation.  Conclusion: Polarity of depression, comorbidity of anxiety disorders, and current episode duration may predict the efficacy of aripiprazole augmentation for TRD including both major depressive disorder and

    The effect of yohimbine treatment (4 mg three times daily) for 3 weeks on salivary secretion was investigated. In healthy volunteers, acute administration of yohimbine increased salivary volume within 1 h to a similar extent before and at the end of the treatment period. In depressed patients treated with tricyclic antidepressants (and exhibiting a reduced salivary flow), yohimbine also acutely increased salivary volume. In contrast, the alpha 2-adrenoceptor antagonist failed to modify resting values measured in the morning (i.e. 10 and 14 h after the last administration in healthy volunteers and depressed patients respectively). This result indicates that alpha 2-adrenoceptor antagonists may have a potential therapeutic use in the treatment of dry mouth caused by tricyclic antidepressant drugs. PMID:1362888

    Chronic hepatitis C is a leading cause of liver-related morbidity and mortality worldwide. If untreated, chronic hepatitis C can progress to advanced liver fibrosis, cirrhosis, liver failure, hepatocellular carcinoma and death. Until recently, treatment of hepatitis C predominantly constituted an immunomodulatory agent, peg-interferon-alfa and ribavirin. In 2011, the first class of directly acting antiviral agents, HCV NS3/4A serine protease inhibitors, was added to peg-interferon-alfa and ribavirin with increased efficacy. In the past year, an NS5B inhibitor, sofosbuvir, has emerged as a potent agent with pangenotypic efficacy, resulting in the first interferon-free regimen for the treatment of hepatitis C. This review summarizes the data that resulted in regulatory approval of sofosbuvir and highlights the future of hepatitis C therapy with sofosbuvir as the backbone of a highly effective antiviral regimen.

    The purpose of this article was to inform the first-line treatment choice between cognitive-behavioral therapy (CBT) or an antidepressant medication for treatment-naive adults with major depressive disorder by defining a neuroimaging biomarker that differentially identifies the outcomes of remission and treatment failure to these interventions. Functional MRI resting-state functional connectivity analyses using a bilateral subcallosal cingulate cortex (SCC) seed was applied to 122 patients from the Prediction of Remission to Individual and Combined Treatments (PReDICT) study who completed 12 weeks of randomized treatment with CBT or antidepressant medication. Of the 122 participants, 58 achieved remission (Hamilton Depression Rating Scale [HAM-D] score ≤7 at weeks 10 and 12), and 24 had treatment failure (treatment and outcome. Receiver operating characteristic curves constructed using brain connectivity measures were used to determine possible classification rates for differential treatment outcomes. The resting-state functional connectivity of the following three regions with the SCC was differentially associated with outcomes of remission and treatment failure to CBT and antidepressant medication and survived application of the subsample permutation tests: the left anterior ventrolateral prefrontal cortex/insula, the dorsal midbrain, and the left ventromedial prefrontal cortex. Using the summed SCC functional connectivity scores for these three regions, overall classification rates of 72%-78% for remission and 75%-89% for treatment failure was demonstrated. Positive summed functional connectivity was associated with remission with CBT and treatment failure with medication, whereas negative summed functional connectivity scores were associated with remission to medication and treatment failure with CBT. Imaging-based depression subtypes defined using resting-state functional connectivity differentially identified an individual's probability of remission or

    Chronically administered antidepressant drugs, particularly selective serotonin (5-HT) reuptake inhibitors (SSRIs), are clinically effective in the treatment of all anxiety disorders, while the clinical effectiveness of "traditional" anxiolytics, such as benzodiazepines (BDZs), is limited to generalised anxiety disorder or acute panic attacks. This implies that animal models of anxiety should be sensitive to SSRIs and other antidepressants in order to have predictive validity. We reviewed the literature on the effects of antidepressants in the so-called animal models of anxiety and found that only the isolation-induced calls in guinea-pig pups may reveal anxiolytic-like action of all antidepressant classes after acute administration. Some other models, such as marble-burying or conditioned-freezing behaviours, and isolation- or shock-induced ultrasonic vocalisation models, may detect anxiolytic-like activity of acutely administered antidepressants, although the sensitivity of these models is usually limited to SSRIs and other drugs affecting 5-HT uptake. The predictive validity of models of "anxiety", such as the plus-maze and light-dark transition tests or stress-induced hyperthermia, appears to be limited to BDZ-related drugs. Far less work has been done on chronic administration of antidepressants in animal anxiety models. Unless and until such studies have been undertaken, the true predictive value of the anxiety models will remain unknown.

  18. Effectiveness and cost-effectiveness of antidepressants in primary care: a multiple treatment comparison meta-analysis and cost-effectiveness model.

    Full Text Available OBJECTIVE: To determine effectiveness and cost-effectiveness over a one-year time horizon of pharmacological first line treatment in primary care for patients with moderate to severe depression. DESIGN: A multiple treatment comparison meta-analysis was employed to determine the relative efficacy in terms of remission of 10 antidepressants (citalopram, duloxetine escitalopram, fluoxetine, fluvoxamine mirtazapine, paroxetine, reboxetine, sertraline and venlafaxine. The estimated remission rates were then applied in a decision-analytic model in order to estimate costs and quality of life with different treatments at one year. DATA SOURCES: Meta-analyses of remission rates from randomised controlled trials, and cost and quality-of-life data from published sources. RESULTS: The most favourable pharmacological treatment in terms of remission was escitalopram with an 8- to 12-week probability of remission of 0.47. Despite a high acquisition cost, this clinical effectiveness translated into escitalopram being both more effective and having a lower total cost than all other comparators from a societal perspective. From a healthcare perspective, the cost per QALY of escitalopram was €3732 compared with venlafaxine. CONCLUSION: Of the investigated antidepressants, escitalopram has the highest probability of remission and is the most effective and cost-effective pharmacological treatment in a primary care setting, when evaluated over a one year time-horizon. Small differences in remission rates may be important when assessing costs and cost-effectiveness of antidepressants.

    Full Text Available Abstract Background The fate of 14 antidepressants along with their respective N-desmethyl metabolites and the anticonvulsive drug carbamazepine was examined in a primary sewage treatment plant (STP and following advanced treatments with ozone (O3. The concentrations of each pharmaceutical compound were determined in raw sewage, effluent and sewage sludge samples by LC-MS/MS analysis. The occurrence of antidepressant by-products formed in treated effluent after ozonation was also investigated. Results Current primary treatments using physical and chemical processes removed little of the compounds (mean removal efficiency: 19%. Experimental sorption coefficients (Kd of each studied compounds were also calculated. Sorption of venlafaxine, desmethylvenlafaxine, and carbamazepine on sludge was assumed to be negligible (log Kd ≤ 2, but higher sorption behavior can be expected for sertraline (log Kd ≥ 4. Ozonation treatment with O3 (5 mg/L led to a satisfactory mean removal efficiency of 88% of the compounds. Screening of the final ozone-treated effluent samples by high resolution-mass spectrometry (LC-QqToFMS did confirm the presence of related N-oxide by-products. Conclusion Effluent ozonation led to higher mean removal efficiencies than current primary treatment, and therefore represented a promising strategy for the elimination of antidepressants in urban wastewaters. However, the use of O3 produced by-products with unknown toxicity.

    Sleep disturbances have long been considered as a cardinal symptom of endogenous depression and dreams in depressed patients usually differ from those of healthy people. The aim of the present study was to investigate dream subjective experiences and their modifications in relation to clinical response in a group of escitalopram-treated depressed patients. Twenty-seven female patients meeting DSM-IV-TR criteria for Major Depressive Disorder (MDD) and starting SSRI therapy were included in the study. Data about psychopathological status and dreaming subjective experiences were collected at baseline (T0), 4 weeks after the beginning of the treatment (T1) and after further 4 weeks of therapy (T2). At T0 dream experience was impaired and negatively toned. Concomitantly with the decrease of symptoms severity, the 8-week escitalopram treatment yielded to significant improvements in the recall of both quantity and quality of dreams; those patients whit lower clinical benefits kept on reporting impaired dream experiences. The results of the present study evidence how the changes in some specific dreaming characteristics, such as the subjective recall of dream activity, the dream recall quality, the dream emotional content and the dream complexity represent reliable markers of the effectiveness of antidepressant therapy.

    Urticaria commonly presents with intensely pruritic wheals, sometimes with edema of the subcutaneous or interstitial tissue. It has a lifetime prevalence of about 20%. Although often self-limited and benign, it can cause significant discomfort, continue for months to years, and uncommonly represent a serious systemic disease or life-threatening allergic reaction. Urticaria is caused by immunoglobulin E- and non-immunoglobulin E-mediated release of histamine and other inflammatory mediators from mast cells and basophils. Diagnosis is made clinically; anaphylaxis must be ruled out. Chronic urticaria is idiopathic in 80% to 90% of cases. Only a limited nonspecific laboratory workup should be considered unless elements of the history or physical examination suggest specific underlying conditions. The mainstay of treatment is avoidance of triggers, if identified. The first-line pharmacotherapy is second-generation H1 antihistamines, which can be titrated to greater than standard doses. First-generation H1 antihistamines, H2 antihistamines, leukotriene receptor antagonists, high-potency antihistamines, and brief corticosteroid bursts may be used as adjunctive treatment. In refractory chronic urticaria, patients can be referred to subspecialists for additional treatments, such as omalizumab or cyclosporine. More than one-half of patients with chronic urticaria will have resolution or improvement of symptoms within a year.

    Yueju is a traditional herbal medicine which consists of five herbs and formulated to treat depression-related syndromes 800 years ago. Yueju is still widely prescribed to treat conditions which include digestive dysfunction and depression. Recently, Yueju has been shown to promote a fast-onset antidepressant effect clinically and in preclinical studies. Because conventional antidepressants have a delayed onset in treating depression, the novelty of Yueju's rapid antidepressant effect and its underlying mechanism are of great significance both clinically and scientifically. To review the use of Yueju for treatment of mood-related syndromes, and particularly its use in depression. To evaluate recent evidence of Yueju rapid antidepressant actions, based on new findings at behavioral and molecular levels. To suggest direction for future studies to address further scientific issues. Reports regarding to the history and current use of Yueju are summarized. Recent progress on rapid antidepressant effects of Yueju, the crucial constituent, Gardenia jasminoides J.Ellis (GJ) and other herbs, are reviewed. The medical need for rapid antidepressant actions, as well as breakthrough findings using ketamine and its limitations are introduced. Studies with Yueju using a number of acute, subacute and chronic behavioral paradigms are compared with ketamine. Findings from clinical reports also support the rapid action of Yueju. Studies examine the contribution of the constituent herb GJ, in rapid antidepressant effects. Importantly, research into the mechanism of Yueju or GJ's antidepressant response indicate the importance of up-regulation in the neural circuit responsible for antidepressant activity, and highlight common and specific molecular signaling by Yueju that may explain why this herb formula has unique antidepressant activity. Preclinical and clinical studies demonstrate that Yueju confers rapid antidepressant effects. The common mechanisms shared both for ketamine and

    Full Text Available Despite of extensive blood product screening and national immunization programs, chronic hepatitis B and C infections continues to be a global problem with high mortality, morbidity and economic impact. Even though acquisition of these infections mostly occurs in childhood, major problems appear in adulthood. Cirrhosis and HCC are two major expected late events related to chronic hepatitis B and C infections. Rarely, children may also face these complications. To avoid these complications and increase the life expectancy in adults treatment of these two type infections should be started in childhood with appropriate patient selection. In contrast to children, adults are luckier in terms of treatment alternatives. They have the chance to use more potent antivirals with higher genetic barrier and pegylated form of interferons. Recently, the use of pegylated interferon and ribavirin combinations has been approved in children in Chronic HCV infection. However, chronic hepatitis B treatment in children is still dependent on the use of one type antiviral drug and conventional interferon. Treatment in early ages with an antiviral agent that has limited genetic barrier may block the chance of treatment or reduce the response rate in adulthood in chronic hepatitis B infection. This burden indicates the necessity of new therapeutic modalities in children. In this term pegylated interferons may be one of the optiones. In this article we aimed to reviewe the efficacy and safety of conventional and pegylated interferons, for the treatment of Hepatitis C and B infections in children.

    Full Text Available Aim. To evaluate the influence of antidepressant therapy with pirlindol on compliance to the long-term treatment and quality of life in patients with cardiovascular diseases and mild to moderate depression. Material and methods. 61 patients with cardiovascular diseases and mild to moderate depression (according to Beck depression scale were randomized into two groups. Patients of intervention group received pirlindol, while patients of control group did not receive this drug. Compliance to cardiovascular and antidepressant treatment were estimated in 3 and 6 months. Adverse reactions and patients self-assessment of their well-being and global satisfaction in treatmen were also registered.  Results. 24 (75%, 2 (6% and 0 patients of intervention group continue pirlindol treatment in 1, 3 and 6 months, respectively. In 3 months of observation patients of intervention group took drugs for cardiovascular diseases more often than these in control group (81% vs 72%, respectively , р<0.05, they also less frequently showed adverse reactions (56% vs 72%, respectively ,p=0.01 and more often — improvement of their well-being (65% vs 50%, respectively , р=0.03. Compliance to cardiovascular therapy did not differ significantly in patients of both groups by the end the study.  Conclusion. Antidepressant therapy with pirlindol did not influence compliance to long-term cardiovascular treatment in patients with cardiovascular diseases and mild to moderate depression, apparently because of low compliance to pirlindol therapy.

    Increasing interest surrounds potential neuroprotective or neurotrophic actions of antidepressants. While growing evidence points to important early clinical and neuropsychological effects of antidepressants, the time-course of any effect on neuronal integrity is unclear. This study used magnetic resonance spectroscopy to assess effects of short-term treatment with escitalopram on N-acetyl-aspartate (NAA), a marker of neuronal integrity. Thirty-nine participants with major depression were randomly assigned to receive either 10 mg escitalopram or placebo daily in a double-blind, parallel group design. On the seventh day of treatment, PRESS data were obtained from a 30×30×20 mm voxel placed in medial frontal cortex. Age and gender-matched healthy controls who received no treatment were also scanned. Levels of NAA were significantly higher in patients treated with escitalopram than in either placebo-treated patients (p<0.01) or healthy controls (p<0.01). Our findings are consistent with the proposition that antidepressant treatment in depressed patients can produce early changes in neuronal integrity.

    Wikinski, Silvia

    2012-01-01

    The term dysthymia is applied to a clinical picture characterized by depressive feelings of low intensity and chronic evolution. Psychiatric nosology includes it among the mood disorders or among neurosis and personality disorders. This ambiguity has empirical consequences, since bibliography examining the efficacy of the different treatments is relatively scarce, in particular if we consider the incidence of the dysthymic disorder, that rounds 3% of general population. In this work the history of the nosology of dysthimia, the efficacy of pharmacological approaches and a brief mention about the efficacy of adding psychotherapy are summarized. Current literature indicates that antidepressants, independently of the group they form part of, are better than placebo, that maintenance treatment should be recommended and that psychotherapy could bring an additional benefit.

    Miravitlles, Marc

    2005-06-11

    Treatment of chronic obstructive pulmonary disease (COPD) has underwent a very important advance in the last five years. It has been developed a new long-lasting anticholynergic drug, tiotrope bromure, which has been found to improve lung function and exercise capacity and to decrease relapses. Also the combined treatment of long lasting beta 2 adrenergics with inhaled steroids (salmeterol/fluticasone and formoterol/budesonide) has proven similar results. However, the response to these new drugs is not the same in all patients. Individual characteristics such as gravity, degree of bronchial hyperresponsiveness, frequency of relapses, comorbidity, etc will determine the response to several agents. Thus, it is necessary to perform a detailed diagnostic study in COPD patients in order to select the best treatment in an individualized form. In the future, new specific antiinflammatories such as phosphodiesterase 4 inhibitors or agents with a potential action in tissue regeneration could lead to new perspectives, as well as to new questions, in COPD treatment.

    Bupropion is widely used for treating bipolar disorder (BD), and especially those with depressive mood, based on its good treatment effect, safety profile, and lower risk of phase shifting. However, increasing evidence indicates that the safety of bupropion in BD patients may not be as good as previously thought. The aim of this study was to summarize data on the treatment effect and safety profile of bupropion in the treatment of BD via a meta-analysis. Electronic search through PubMed and ClinicalTrials.gov was performed. The inclusion criteria were: (i) studies comparing changes in disease severity before and after bupropion treatment or articles comparing the treatment effect of bupropion in BD patients with those receiving other standard treatments; (ii) articles on clinical trials in humans. The exclusion criteria were (i) case reports/series, and (ii) nonclinical trials. All effect sizes from 10 clinical trials were pooled using a random effects model. We examined the possible confounding variables using meta-regression and subgroup analysis. Bupropion significantly improved the severity of disease in BD patients (P < 0.001), and the treatment effect was similar to other antidepressants/standard treatments (P = 0.220). There were no significant differences in the dropout rate (P = 0.285) and rate of phase shifting (P = 0.952) between BD patients who received bupropion and those who received other antidepressants. We could not perform a detailed meta-analysis of every category of antidepressant, nor could we rule out the possible confounding effect of concurrent psychotropics or include all drug side effects. Furthermore, the number of studies recruited in the meta-analysis was relatively small. Our findings reconfirm the benefits of bupropion for the treatment of bipolar depression, which are similar to those of other antidepressants. However, the rate of phase shifting with bupropion usage was not as low compared to other antidepressants as

    Full Text Available Brian E Lacy, L Campbell LevySection of Gastroenterology and Hepatology, Dartmouth-Hitchcock Medical Center, Lebanon NH, USAAbstract: Chronic constipation is highly prevalent, reduces patients’ quality of life, and imposes a significant health care burden on society. Lifestyle modifications and over-the-counter agents improve symptoms of constipation in some patients, however many patients have persistent symptoms and require the use of prescription medications. Three prescription medications are currently Food and Drug Administration (FDA approved and available for the treatment of chronic constipation in adults. This review will focus on lubiprostone, the newest medication available for the treatment of chronic constipation. Lubiprostone is a bicyclic fatty acid metabolite analogue of prostaglandin E1. It activates specific chloride channels in the gastrointestinal tract to stimulate intestinal fluid secretion, increase gastrointestinal transit, and improve symptoms of constipation. This article will provide a brief overview on chloride channel function in the gastrointestinal tract, describe the structure, function, and pharmacokinetics of lubiprostone, and discuss the safety and efficacy of this new medication.Keywords: chloride, chloride channels, constipation, functional bowel disorders, gastrointestinal motility, intestinal secretion, irritable bowel syndrome, lubiprostone

    2014-12-01

    Chronic pain in children and young adults occurs frequently and contributes to early disability as well as personal and familial distress. A biopsychosocial approach to evaluation and treatment is recommended. Within this approach, there is a role for pharmacologic intervention. A variety of medications are used for chronic pain conditions in pediatric patients. Medication classes include anticonvulsants, muscle relaxants, antidepressants, opioids, local anesthetics, and anti-inflammatory drugs. Data is sparse, and most medications are used without condition-specific approval by national regulatory agencies such as the Food and Drug Administration in the US and the European Medicines Agency. In the absence of evidence on which to base practice, optimal drug therapy decisions rest on understanding proposed mechanisms of pain conditions, extrapolation from adult data-when such exists, and empirical and experiential knowledge. Drug delivery systems have evolved, and practitioners have to decide amongst not only medication classes, but also routes of delivery. Opioids are not recommended for use by non-pain specialists for the treatment of pediatric chronic pain, and even then the issues are more complex than can be addressed here. This article reviews the major medications used for pediatric chronic pain conditions.

    Antidepressant drugs and psychotherapy combined are more effective in treating mood disorders than either treatment alone, but the neurobiological basis of this interaction is unknown. To investigate how antidepressants influence the response of mood-related systems to behavioral experience, we used a fear-conditioning and extinction paradigm in mice. Combining extinction training with chronic fluoxetine, but neither treatment alone, induced an enduring loss of conditioned fear memory in adult animals. Fluoxetine treatment increased synaptic plasticity, converted the fear memory circuitry to a more immature state, and acted through local brain-derived neurotrophic factor. Fluoxetine-induced plasticity may allow fear erasure by extinction-guided remodeling of the memory circuitry. Thus, the pharmacological effects of antidepressants need to be combined with psychological rehabilitation to reorganize networks rendered more plastic by the drug treatment.

  15. Elevated stress-hemoconcentration in major depression is normalized by antidepressant treatment: secondary analysis from a randomized, double-blind clinical trial and relevance to cardiovascular disease risk.

    Directory of Open Access Journals (Sweden)

    Ma-Li Wong

    Full Text Available BACKGROUND: Major depressive disorder (MDD is an independent risk factor for cardiovascular disease (CVD; the presence of MDD symptoms in patients with CVD is associated with a higher incidence of cardiac complications following acute myocardial infarction (MI. Stress-hemoconcentration, a result of psychological stress that might be a risk factor for the pathogenesis of CVD, has been studied in stress-challenge paradigms but has not been systematically studied in MDD. METHODS: Secondary analysis of stress hemoconcentration was performed on data from controls and subjects with mild to moderate MDD participating in an ongoing pharmacogenetic study of antidepressant treatment response to desipramine or fluoxetine. Hematologic and hemorheologic measures of stress-hemoconcentration included blood cell counts, hematocrit, hemoglobin, total serum protein, and albumin, and whole blood viscosity. FINDINGS: Subjects with mild to moderate MDD had significantly increased hemorheologic measures of stress-hemoconcentration and blood viscosity when compared to controls; these measures were correlated with depression severity. Measures of stress-hemoconcentration improved significantly after 8 weeks of antidepressant treatment. Improvements in white blood cell count, red blood cell measures and plasma volume were correlated with decreased severity of depression. CONCLUSIONS: Our secondary data analyses support that stress-hemoconcentration, possibly caused by decrements in plasma volume during psychological stress, is present in Mexican-American subjects with mild to moderate MDD at non-challenged baseline conditions. We also found that after antidepressant treatment hemorheologic measures of stress-hemoconcentration are improved and are correlated with improvement of depressive symptoms. These findings suggest that antidepressant treatment may have a positive impact in CVD by ameliorating increased blood viscosity. Physicians should be aware of the potential

    Full Text Available Background. Poisoning with tricyclic antidepressants (TCAs is still a major concern for emergency physicians and intensivists. Concomitant ingestion of other psychoactive drugs especially benzodiazepines with TCAs may make this clinical situation more complex. This study aimed to compare the arterial blood gas (ABG values and the outcome of treatment in patients with coingestion of TCA and benzodiazepine (TCA + BZD poisoning and TCA poisoning alone. Methods. In this cross-sectional study which was carried out in a tertiary care university hospital in Iran, clinical and paraclinical characteristics of one hundred forty TCA only or TCA + BZD poisoned patients (aged 18–40 years were evaluated. ABG analysis was done on admission in both groups. Outcomes were considered as survival with or without complication (e.g., intubation and the frequency of TCA poisoning complications. Results. Arterial pH was significantly lower in TCA + BZD poisoning group compared with TCA only poisoning group (7.34 ± 0.08 and 7.38 ± 0.08, resp.; P=0.02. However, other complications such as seizure, and the need for the endotracheal intubation were not significantly different. All patients in both groups survived. Conclusions. Concomitant TCA plus BZD poisoning may make the poisoned patients prone to a lower arterial pH level on hospital admission which may potentially increases the risk of cardiovascular complications in TCA poisoning.

    Studies have suggested that discontinuation of treatment in depressed patients is associated with their perceptions about their treatment. We surveyed 403 adults treated for major depressive disorder with a selective serotonin reuptake inhibitor (SSRI) 3 months after onset of treatment to assess their interactions with clinicians, reasons they stopped SSRI treatment, and SSRI side effects (SEs). Bothersome SEs, poorer instruction by physicians about SSRI SEs, and self-reported change in depression, sex, marital status, and employment were significantly (P < 0.05) associated with discontinuation. Logistic regression examined the associations between patients' perceptions during treatment planning and SSRI discontinuation. Seventeen percent of patients felt uninvolved in treatment decisions, 9% disagreed with the diagnosis, and 24% subsequently stopped treatment. Elevated risk of discontinuation was found among patients who felt uninvolved in treatment decisions (unadjusted risk ratio [RR], 2.3; 95% confidence interval [CI], 1.2-4.3) and those who disagreed with the diagnosis (RR, 2.0; CI, 0.9-4.4). Patients who both felt uninvolved and disagreed with the diagnosis were 7-fold as likely to discontinue their SSRI (RR, 7.3; CI, 1.5-36.3) compared with those who felt neither uninvolved nor disagreed. Selective serotonin reuptake inhibitor SEs, specific interactions with clinicians, self-assessed outcomes, and sociodemographics did not explain these associations. To improve adherence to medications, clinicians should consider patients' perceptions about their involvement in treatment decisions and agreement with their diagnosis.

    The objective of this manuscript is to report associations between baseline depressive severity and (1) baseline sociodemographic and clinical characteristics, (2) treatment outcomes, and (3) differential outcomes for three treatment groups. Six hundred and sixty-five outpatients with nonpsychotic, major depressive disorder were prospectively randomized to treatment with either a selective serotonin reuptake inhibitor (SSRI) monotherapy (escitalopram plus placebo) or one of two antidepressant medication combinations (bupropion-sustained release plus escitalopram, or venlafaxine-extended release plus mirtazapine). For purposes of these analyses, participants were divided into four groups based on baseline severity by the 16-item Quick Inventory of Depressive Symptomatology - Self-Report (QIDS-SR16) total score: mild (0–10) [N=81], moderate (11–15) [N=238], severe (16–20) [N=260] and very severe (21–27) [N=67]. Treatment outcomes at 12 and 28 weeks were compared among the four severity groups. A history of childhood neglect and/or abuse was strongly associated with the severity of adult depression (1/2 of participants in the very severy group versus 1/5–1/4 of those in the mild group reported abuse and/or neglect). The degree of suicidality (e.g., 15/.4% of the very severe group ever attempted suicide versus none in the mild group), the number of suicide attempts (e.g., mean of .41 +/− 1.99 suicide attempts in the severe group versus o.o +/−0.0 in the mild group) and severity of suicidality (e.g., 9.2% of participants in very severe group had a plan or made a gesture versus 5.6% in moderate group and none in the mild group) were increased in more severe groups. Participants with a greater baseline depressive severity reported significantly more psychiatric comorbitities (e..g. [at p < 0.05] increased rates of agoraphobia, bulimia, generalized anxiety, hypocondriasis, panic disorder, post-traumatic stress disorder, social phobia and somatoform disorder

    In the present study, the amino acids which have the possibility for the therapeutic efficacy of imipramine were explored and compared between Wistar Kyoto rats, an animal model of depression, and Wistar rats as a normal model. The antidepressant-like effect caused by chronic imipramine treatment was confirmed by decreased immobility in the forced swimming test. Chronic imipramine administration altered the amino acid dynamics in the brain. In the striatum, the concentrations of asparagine, glutamine and methionine were significantly increased by chronic imipramine administration. In the thalamus and hypothalamus, chronic imipramine administration significantly decreased the valine concentration. On the other hand, no amino acid was altered by chronic imipramine administration in the hippocampus, brain stem and cerebellum. In addition, lower concentration of asparagine in the prefrontal cortex of WKY rats was improved by chronic imipramine administration. This amelioration only in WKY rats may be a specific effect of chronic imipramine administration under the depressive state. In conclusion, chronic imipramine administration altered the several amino acid dynamics in the brain. Modification of the amino acid metabolism in the brain may provide a new strategy in the development of therapeutic treatment of major depression.

    1,2,3,4-Tetrahydroisoquinoline (TIQ) is an exo- and endogenous amine naturally present in mammalian brain which displays antidepressant-like effect in various animal models: the forced swim test (FST) and chronic mild stress (CMS) paradigm in rats. To elucidate this action we compared the effects of TIQ with imipramine, a classic antidepressant drug and one of the most clinically effective. Applied behavioral tests showed that TIQ produced an antidepressant-like effect with a potency comparable to that of imipramine. TIQ (25-50mg/kg i.p.), similarly to imipramine (10-30mg/kg i.p.), reduced the immobility time in FST and completely reversed the decrease in sucrose intake caused by CMS in the rat. In addition, in order to avoid the possible psychostimulating effect of TIQ we examined the influence of its administration on locomotor activity in rats. TIQ, like imipramine, produced a reduction in horizontal locomotor activity. This suggested that TIQ did not have psychostimulant properties and that prolonged swimming in the FST was a result of an increased motivation to escape from the stressful situation. The biochemical analyses have shown that TIQ activates monoaminergic systems as a reversible monoamine oxidase (MAO) inhibitor and free radical scavenger. Beyond the activation of noradrenaline and serotonin systems, TIQ also moderately affects the dopamine system. On the basis of the presented behavioral and biochemical studies we suggest that TIQ is a potential new antidepressant which may be effective for the depression therapy in a clinical setting.

    Urticaria is a common and often debilitating dermatological condition defined by the sudden appearance of wheals, angioedema or both. It is further classified into specific subtypes based on duration and specific triggers. Awareness and understanding of urticaria are important to ensure a correct initial diagnosis and initiate appropriate guideline-based treatment outlining a stepwise approach. However, in chronic urticaria, approximately 50% of patients are refractory to the first step, the use of licensed doses of second-generation H1-antihistamines. If the second step, an increase in the dose of the second-generation H1-antihistamines, is also not successful, in the third step omalizumab (Xolair™, Novartis Pharma AG(©)/Genentech, Inc.(©)), an anti-IgE therapy, is recommended as an add-on. Of all alternative treatments mentioned in the guidelines, omalizumab is currently the only licensed treatment for H1-antihistamine-refractory chronic spontaneous urticaria, has a favorable risk/benefit ratio and was well tolerated in clinical studies.

    Terminalia catappa L. belonging to Combretaceae family is a folk medicine, known for its multiple pharmacological properties, but the neuro-modulatory effect of TC against chronic mild stress was seldom explored. The present study was designed to elucidate potential antidepressant-like effect of Terminalia cattapa (leaf) hydro-alcoholic extract (TC) by using CMS model for a period of 7 weeks. Identification of hydrolysable tannins was done by using LC-MS. After the CMS exposure, mice groups were administered with imipramine (IMP, 10mg/kg, i.p.) and TC (25, 50 and 100mg/kg of TC, p.o.). Behavioural paradigms used for the study included forced swimming test (FST), tail suspension test (TST) and sucrose preference test (SPT). After behavioural tests, monoamine neurotransmitter, cortisol, AchE, oxidative stress levels and mRNA expression studies relevant to depression were assessed. TC supplementation significantly reversed CMS induced immobility time in FST and other behavioural paradigms. Moreover, TC administration significantly restored CMS induced changes in concentrations of hippocampal neurotransmitters (5-HT, DA and NE) as well as levels of acetyl cholinesterase, cortisol, monoamine oxidases (MAO-A, MAO-B), BDNF, CREB, and p-CREB. It suggests that TC supplementation could supress stress induced depression by regulating monoamine neurotransmitters, CREB, BDNF, cortisol, AchE level as well as by amelioration of oxidative stress. Hence TC can be used as a complementary medicine against depression-like disorder.

    Presented is a case of chronic methicillin-resistant Staphylococcus aureus osteomyelitis, which was unsuccessfully treated with multiple courses of debridement and potent antibiotic therapies. Amputation of the patient's lower limb was believed to be the only option remaining. A compassionate access program, with approval from the US Food and Drug Administration and the institutional review board, enabled the patient to undergo a course of treatment with oral fusidic acid (CEM-102). The patient tolerated the drug well, with no significant toxicities noted to date. His infection improved rapidly, his flap healed, he has returned to work part-time, and he continues to take daily suppressive doses of oral CEM-102.

    Accumulating evidence suggests an association between patient pretreatment expectations and numerous health outcomes. However, it remains unclear if and how expectations relate to outcomes after treatments in multidisciplinary pain programs. The present study aims at investigating the predictive association between expectations and clinical outcomes in a large database of chronic pain patients. In this observational cohort study, participants were 2272 patients treated in one of 3 university-affiliated multidisciplinary pain treatment centers. All patients received personalized care, including medical, psychological, and/or physical interventions. Patient expectations regarding pain relief and improvements in quality of life and functioning were measured before the first visit to the pain centers and served as predictor variables. Changes in pain intensity, depressive symptoms, pain interference, and tendency to catastrophize, as well as satisfaction with pain treatment and global impressions of change at 6-month follow-up, were considered as treatment outcomes. Structural equation modeling analyses showed significant positive relationships between expectations and most clinical outcomes, and this association was largely mediated by patients' global impressions of change. Similar patterns of relationships between variables were also observed in various subgroups of patients based on sex, age, pain duration, and pain classification. Such results emphasize the relevance of patient expectations as a determinant of outcomes in multimodal pain treatment programs. Furthermore, the results suggest that superior clinical outcomes are observed in individuals who expect high positive outcomes as a result of treatment.

    Studies have shown that the scientific literature has overestimated the efficacy of antidepressants for depression, but other indications for these drugs have not been considered. To examine reporting biases in double-blind, placebo-controlled trials on the pharmacologic treatment of anxiety disorders and quantify the extent to which these biases inflate estimates of drug efficacy. We included reviews obtained from the US Food and Drug Administration (FDA) for premarketing trials of 9 second-generation antidepressants in the treatment of anxiety disorders. A systematic search for matching publications (until December 19, 2012) was performed using PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials. Double data extraction was performed for the FDA reviews and the journal articles. The Hedges g value was calculated as the measure of effect size. Reporting bias was examined and classified as study publication bias, outcome reporting bias, or spin (abstract conclusion not consistent with published results on primary end point). Separate meta-analyses were conducted for the 2 sources, and the effect of publication status on the effect estimates was examined using meta-regression. The findings of 41 of the 57 trials (72%) were positive according to the FDA, but 43 of the 45 published article conclusions (96%) were positive (P antidepressants for anxiety disorders. Although these biases did not significantly inflate estimates of drug efficacy, reporting biases led to significant increases in the number of positive findings in the literature.

    Few reliable predictors indicate which depressed individuals respond to antidepressants. Several studies suggest that a history of early-life trauma predicts poorer response to antidepressant therapy but results are variable and limited in adults. The major goal of the present study was to evaluate the role of early-life trauma in predicting acute response outcomes to antidepressants in a large sample of well-characterized patients with major depressive disorder (MDD). The international Study to Predict Optimized Treatment for Depression (iSPOT-D) is a randomized clinical trial with enrollment from December 2008 to January 2012 at eight academic and nine private clinical settings in five countries. Patients (n=1008) meeting DSM-IV criteria for MDD and 336 matched healthy controls comprised the study sample. Six participants withdrew due to serious adverse events. Randomization was to 8 weeks of treatment with escitalopram, sertraline or venlafaxine with dosage adjusted by the participant's treating clinician per routine clinical practice. Exposure to 18 types of traumatic events before the age of 18 was assessed using the Early-Life Stress Questionnaire. Impact of early-life stressors-overall trauma 'load' and specific type of abuse-on treatment outcomes measures: response: (⩾50% improvement on the 17-item Hamilton Rating Scale for Depression, HRSD17 or on the 16-item Quick Inventory of Depressive Symptomatology-Self-Rated, QIDS_SR16) and remission (score ⩽7 on the HRSD17 and ⩽5 on the QIDS_SR16). Trauma prevalence in MDD was compared with controls. Depressed participants were significantly more likely to report early-life stress than controls; 62.5% of MDD participants reported more than two traumatic events compared with 28.4% of controls. The higher rate of early-life trauma was most apparent for experiences of interpersonal violation (emotional, sexual and physical abuses). Abuse and notably abuse occurring at ⩽7 years of age predicted poorer outcomes

    Antidepressant drugs are a mainstay in psychiatric treatment and have the ability to influence neural substrates related to social bonding and interaction. This article explores the potential neurobiological overlap between social attachment and antidepressant mechanisms and reviews work related to the effects of antidepressants on separation distress, social affiliation, dominance hierarchies, romantic love, and socio-emotional processing. It is proposed that similarities between antidepressant pharmacology and the neurobiological effects of an effective care-giver may help create a sense of safety that in turn promotes changes in behavior and mood.

    1998-05-13

    The conservative medical treatment of chronic pancreatitis entails dealing prevalently with exocrine and endocrine insufficiency, diet and pain. As steatorrhoea can cause malabsorption, it is advisable to reduce first the fat content of the diet and secondly to prescribe, where necessary, pancreatic enzymes. Several factors can lead to a poor therapeutic enzyme effect. Attention should be given to the pharmacological properties of the enzyme-preparation and to the secretion of acid in the stomach. An endocrine insufficiency is more difficult to treat compared to a classical diabetes mellitus, for lack of endocrine regulatory mechanisms. Pain is the consequence of several pathophysiological processes. Before initiating analgetic treatment, a minimal diagnostic program should be completed allowing the exclusion of those primary causes of pain which require an alternative approach such as interventional endoscopy or surgery.

    Treatment non-adherence in psycho-pharmacotherapy remains a significant challenge to the effective clinical management of psychiatric disorders, especially among underserved racial/ethnic groups. This article introduces motivational pharmacotherapy, an approach that integrates motivational interviewing into psycho-pharmacotherapy sessions in order to increase treatment adherence. We describe what aspects of motivational interviewing were incorporated into motivational pharmacotherapy and how we tailored the intervention to the clinical and cultural characteristics of monolingual Spanish-speaking immigrants with major depressive disorder. Transcriptions of the interactions between psychiatrists and patients help illustrate this approach. In our experience, motivational pharmacotherapy differs substantially from standard pharmacotherapy in how it recasts clinicians and patients as equal experts, prioritizes patients' motivation to engage in treatment rather than clinicians' multiple inquiries about symptoms, encourages patients' self-efficacy to overcome barriers, and attends to the momentum of patients' language about commitment to change. We also found that motivational pharmacotherapy can be feasibly incorporated into medication treatment, can be tailored to patients' culture and disorder, and may help increase adherence to psycho-pharmacotherapy.

    Full Text Available Depression is one of the most frequent and severe mental disorder. Since the discovery of antidepressant properties of the imipramine and then after of other tricyclic compounds, several classes of psychotropic drugs have shown be effective in treating major depressive disorder. However, there is a wide range of variability in response to antidepressants that might lead to non response or partial response or in increased rate of relapse or recurrence. The mechanisms of response to antidepressant therapy are poorly understood, and few biomarkers are available than can predict response to pharmacotherapy. Here, we will first review markers that can be used to predict response to pharmacotherapy, such as markers of drug metabolism or blood-brain barrier function, the activity of specific brain areas or neurotransmitter systems, hormonal dysregulations or plasticity, and related molecular targets. We will describe both clinical and preclinical studies and describe factors that might affect the expression of these markers, including environmental or genetic factors and comorbidities. This information will permit us to suggest practical recommendations and innovative treatment strategies to improve therapeutic outcomes.

    Science.gov (United States)

    Howland, Robert H

    2016-07-01

    Antidepressant, atypical antipsychotic, and hallucinogen drugs mediate their actions in part by interactions with the serotonin-2A (5HT2A) receptor. Serotonergic hallucinogen drugs, such as psilocybin, bind most potently as agonists at the 5HT2A receptor, producing profound changes in perception, mood, and cognition. Some of these drugs have been or are currently being investigated in small Phase 2 studies for depression, alcoholism, smoking cessation, anxiety, and posttraumatic stress disorder. However, unlike the synergistic effects of combining antidepressant and atypical antipsychotic drugs, the potential therapeutic effects of hallucinogen drugs may be attenuated by the concurrent use of these medications because antidepressant and atypical antipsychotic drugs desensitize and/or down-regulate 5HT2A receptors. This finding has important implications for optimizing the potential therapeutic use of hallucinogen drugs in psychiatry. [Journal of Psychosocial Nursing and Mental Health Services, 54(7), 21-24.].

    Full Text Available ABSTRACTOBJECTIVE: To report the clinical and functional results from arthroscopic release of the short radial extensor of the carpus (SREC in patients with chronic lateral epicondylitis that was refractory to conservative treatment. METHODS: Over the period from January 2012 to November 2013, 15 patients underwent arthroscopic treatment. The surgical technique used was the one described by Romeo and Cohen, based on anatomical studies on cadavers. The inclusion criteria were that the patients needed to present lateral epicondylitis and that conservative treatment (analgesics, anti-inflammatory agents, corticoid infiltration or physiotherapy had failed over a period of more than six months. The patients were evaluated based on the elbow functional score of the Mayo Clinic, Nirschl's staging system and a visual analog scale (VAS for pain. RESULTS: A total of 15 patients (9 men and 6 women were included. The mean Mayo elbow functional score after the operation was 95 (ranging from 90 to 100. The pain VAS improved from a mean of 9.2 before the operation to 0.64 after the operation. On Nirschl's scale, the patients presented an improvement from a mean of 6.5 before the operation to approximately one. There were significant differences from before to after the surgery for the three functional scores used ( p 0.05. CONCLUSION: Arthroscopic treatment for lateral epicondylitis was shown to be a safe and effective therapeutic option when appropriately indicated and performed, in refractory cases of chronic lateral epicondylitis. It also allowed excellent viewing of the joint space for diagnosing and treating associated pathological conditions, with a minimally invasive procedure.

    Full Text Available Siegfried Kasper, Gerald PailDepartment of Psychiatry and Psychotherapy, Medical University of Vienna, AustriaAbstract: Tricyclic antidepressants (TCAs are among the most effective antidepressants available, although their poor tolerance at usual recommended doses and toxicity in ­overdose make them difficult to use. While selective serotonin reuptake inhibitors (SSRIs are ­better tolerated than TCAs, they have their own specific problems, such as the aggravation of sexual dysfunction, interaction with coadministered drugs, and for many, a discontinuation syndrome. In addition, some of them appear to be less effective than TCAs in more severely depressed patients. Increasing evidence of the importance of norepinephrine in the etiology of depression has led to the development of a new generation of antidepressants, the serotonin and ­norepinephrine reuptake inhibitors (SNRIs. Milnacipran, one of the pioneer SNRIs, was designed from theoretic considerations to be more effective than SSRIs and better tolerated than TCAs, and with a simple pharmacokinetic profile. Milnacipran has the most balanced potency ratio for reuptake inhibition of the two neurotransmitters compared with other SNRIs (1:1.6 for milnacipran, 1:10 for duloxetine, and 1:30 for venlafaxine, and in some studies milnacipran has been shown to inhibit norepinephrine uptake with greater potency than serotonin (2.2:1. Clinical studies have shown that milnacipran has efficacy comparable with the TCAs and is superior to SSRIs in severe depression. In addition, milnacipran is well tolerated, with a low potential for pharmacokinetic drug–drug interactions. Milnacipran is a first-line therapy suitable for most depressed patients. It is frequently successful when other treatments fail for reasons of efficacy or tolerability.Keywords: milnacipran, SNRI, antidepressant efficacy, tolerability

    Several pro-inflammatory cytokines have been implicated in depression and in antidepressant response. This exploratory analysis assessed: 1) the extent to which baseline cytokine levels predicted positive antidepressant response to ketamine; 2) whether ketamine responders experienced acute changes in cytokine levels not observed in non-responders; and 3) whether ketamine lowered levels of pro-inflammatory cytokines, analogous to the impact of other antidepressants. Data from double-blind, placebo-controlled studies of patients with major depressive disorder (MDD) or bipolar disorder (BD) who received a single infusion of sub-anesthetic dose ketamine were used (N = 80). Plasma levels of the eight cytokines were measured at baseline and at 230 min, 1 day, and 3 days post-ketamine. A significant positive correlation was observed between sTNFR1 and severity of depression at baseline. Cytokine changes did not correlate with changes in mood nor predict mood changes associated with ketamine administration. Ketamine significantly increased IL-6 levels and significantly decreased sTNFR1 levels. IL-6 and TNF-α levels were also significantly higher-and sTNFR1 levels were significantly lower-in BD compared to MDD subjects. The functional significance of this difference is unknown. Changes in cytokine levels post-ketamine were not related to antidepressant response, suggesting they are not a primary mechanism involved in ketamine's acute antidepressant effects. Taken together, the results suggest that further study of cytokine levels is warranted to assess their potential role as a surrogate outcome in the rapid antidepressant response paradigm.

    In 2001, the Canadian Psychiatric Association and the Canadian Network for Mood and Anxiety Treatments (CANMAT) partnered to produce evidence-based clinical guidelines for the treatment of depressive disorders. A revision of these guidelines was undertaken by CANMAT in 2008-2009 to reflect advances in the field. This article, one of five in the series, reviews new studies of psychotherapy in the acute and maintenance phase of MDD, including computer-based and telephone-delivered psychotherapy. The CANMAT guidelines are based on a question-answer format to enhance accessibility to clinicians. Evidence-based responses are based on updated systematic reviews of the literature and recommendations are graded according to the Level of Evidence, using pre-defined criteria. Lines of Treatment are identified based on criteria that included evidence and expert clinical support. Cognitive-Behavioural Therapy (CBT) and Interpersonal Therapy (IPT) continue to have the most evidence for efficacy, both in acute and maintenance phases of MDD, and have been studied in combination with antidepressants. CBT is well studied in conjunction with computer-delivered methods and bibliotherapy. Behavioural Activation and Cognitive-Behavioural Analysis System of Psychotherapy have significant evidence, but need replication. Newer psychotherapies including Acceptance and Commitment Therapy, Motivational Interviewing, and Mindfulness-Based Cognitive Therapy do not yet have significant evidence as acute treatments; nor does psychodynamic therapy. Although many forms of psychotherapy have been studied, relatively few types have been evaluated for MDD in randomized controlled trials. Evidence about the combination of different types of psychotherapy and antidepressant medication is also limited despite widespread use of these therapies concomitantly. CBT and IPT are the only first-line treatment recommendations for acute MDD and remain highly recommended for maintenance. Both computer-based and

    No study has examined the effect of cognitive-behavioral therapy (CBT) on moderate-severe major depressive disorders (MDD) in China. The objective of this study was to evaluate the effect of CBT, antidepressants alone (MED), combined CBT and antidepressants (COMB) and standard treatment (ST; i.e., receiving psycho-educational intervention and/or medication treatment determined by treating psychiatrists) on depressive symptoms and social functioning in Chinese patients with moderate-severe MDD. A total of 180 patients diagnosed with MDD according to ICD-10 were randomly allocated to one of the four treatment regimens for a period of 6 months. Depressive symptoms were measured using the Hamilton Rating Scale for Depression (HAMD) and the Quick Inventory of Depressive Symptomatology-Self-Report (C-QIDS-SR). Remission threshold was defined as a C-QIDS-SR total score of <5. Social functioning was evaluated with the Work and Social Adjustment Scale (WSAS). All outcome measures were evaluated at entry, and at 3- and 6-months follow-up. At the 6-months assessment, the remission rates in the whole sample (n=96), the MED, the CBT, the COMB and the ST groups were 54.2%, 48%, 75%, 53.5% and 50%, respectively. Following the treatment periods, there was no significant difference in any of the study outcomes between the four groups. However, the CBT showed the greatest effect in the HAMD total score with the effect size=0.94, whereas the ST has only a moderate effect size in the WSAS total score (effect size=0.47). The findings support the feasibility and effectiveness of CBT as a psychosocial intervention for Chinese patients with moderate-severe MDD. We also found that single treatment using MED or CBT performed equally well as the combined CBT-antidepressant treatment in controlling the remission. The study provided important knowledge to inform the mental health care planning in China. © 2013 Elsevier B.V. All rights reserved.

    Band-pass filtering is a novel statistical methodology that proposes that filtering out data from trial sites generating non-plausible high or low levels of placebo response can yield a more accurate effect size and greater separation of active drug (when efficacious) from placebo. We applied band-pass filters to re-analyze data from a negative antidepressant trial (NCT00739908) evaluating CX157 (a reversible and selective monoamine oxidase inhibitor-A) versus placebo. 360 patients from 29 trial sites were randomized to either CX157 treatment (n=182) or placebo (n=178). We applied two filters of7 points (filter #1) or9 points (filter #2) mean change of the total MADRS placebo scores for each site. Trial sites that had mean placebo MADRS score changes exceeding the boundaries of these band-pass filter thresholds were considered non-informative and all of the data from these sites were excluded from the post-hoc re-analysis. The two band-pass filters reduced the sample of informative patients from 353 patients in the mITT population to 62 in filter #1 and 152 in the filter #2 group. The placebo response was reduced from 31.1% in the mITT population to 9.4% with filter #1 and 20.8% with filter #2. MMRM analysis revealed a non-statistically significant trend of p=0.13 and 0.16 for the two filters in contrast to the mITT population (p= 0.58). Our findings support the band-pass filter hypothesis and highlight issues related to site-based scoring variability and inappropriate subject selection that may contribute to trial failure.

    Full Text Available The clinical effect of electroacupuncture on depression is widely recognized. However, the signal transduction pathways and target proteins involved remain unclear. In the present study, rat models of chronic restraint stress were used to explore the mechanism by which electroacupuncture alleviates depression. Rats were randomly divided into control, model, and electroacupuncture groups. Chronic restraint stress was induced in the model and electroacupuncture groups by restraining rats for 28 days. In the electroacupuncture group, electroacupuncture pretreatment at Baihui (GV20 and Yintang (GV29 acupoints was performed daily (1 mA, 2 Hz, discontinuous wave, 20 minutes prior to restraint for 28 days. Open field tests and body weight measurements were carried out to evaluate the depressive symptoms at specific time points. On day 28, the crossing number, rearing number, and body weights of the model group were significantly lower than those in the control group. Behavior test results indicated that rat models of depressive-like symptoms were successfully established by chronic restraint stress combined with solitary raising. On day 28, an isobaric tag for a relative and absolute quantitation-based quantitative proteomic approach was performed to identify differentially expressed proteins in hippocampal samples obtained from the model and electroacupuncture groups. The potential function of these differential proteins was predicted through the use of the Cluster of Orthologous Groups of proteins (COG database. Twenty-seven differential proteins (uncharacteristic proteins expected were selected from the model and electroacupuncture groups.

    Full Text Available Animal models of anxious disorders found in humans, such as panic disorder and posttraumatic stress disorder, usually include spontaneous and conditioned fear that triggers escape and avoidance behaviors. The development of a panic disorder model with a learned component should increase knowledge of mechanisms involved in anxiety disorders. In our ethological model of extreme anxiety in the rat, forced apnea was combined with cold water vaporization in an inescapable situation. Based on the reactions of vehicle controls, behaviors involved in paroxysmic fear were passive (freezing and active (jumping reactions. Our results show that subchronic fluoxetine (5 mg/kg, IP, 21 days and imipramine (10 mg/kg, IP, 14 days administration alleviated freezing and jumping behaviors, whereas acute fluoxetine (1 mg/kg, IP provoked opposite effects. Acute low dose of diazepam (1 mg/kg, IP was not effective, whereas the higher dose of 3 mg/kg, IP, and clonazepam (1 mg/kg, IP only had an effect on jumping. Paroxysmic fear generated in this experimental condition may therefore mimic the symptomatology observed in patients with anxiety disorders.

    According to both in vitro and in vivo data P-glycoprotein (P-gp) may restrict the uptake of several antidepressants into the brain, thus contributing to the poor success rate of current antidepressant therapies. The therapeutic activity of citalopram resides in the S-enantiomer, whereas the R-enantiomer is practically devoid of serotonin reuptake potency. To date, no in vivo data are available that address whether the enantiomers of citalopram and its metabolites are substrates of P-gp. P-gp knockout (abcb1ab (-/-)) and wild-type (abcb1ab (+/+)) mice underwent acute (single-dose) and chronic (two daily doses for 10 days) treatment with citalopram (10mg/kg) or escitalopram (5mg/kg) Serum and brain samples were collected 1-6h after the first or last i.p. injection for subsequent drug analysis by an enantioselective HPLC method. In brain, 3-fold higher concentrations of S- and R-citalopram, and its metabolites, were found in abcb1ab (-/-) mice than in abcb1ab (+/+) mice after both acute and chronic citalopram treatments. After escitalopram treatment, the S-citalopram brain concentration was 3-5 times higher in the knockout mice than in controls. The results provide novel evidence that the enantiomers of citalopram are substrates of P-gp. Possible clinical and toxicological implications of this finding need to be further elucidated.

    Chronic inflammatory demyelinating polyneuropathy (CIDP) is one of the acquired demyelinating neuropathies and is considered to be immune mediated. Diagnosis is typically based on clinical history, neurologic examination, electrophysiologic studies, CSF studies, and pathologic examination. Early diagnosis and treatment is important to prevent irreversible axonal loss and optimize improvement in function. The first-line agents for treatment are intravenous immunoglobulin (IVIg), corticosteroids, and plasmapheresis, which have all been demonstrated to be effective in controlled studies. Studies have not shown a significant difference between these three treatments, and the initial choice of therapy is often based on availability, cost, ease of administration, and side effect profile. If patients do not respond to one of these agents, they may respond to one of the others and sometimes in combination. If the first-line agents are not effective, chemotherapeutic or immunosuppressive agents may be considered. There are limited controlled studies of these modalities, and they are often used in conjunction with a first-line treatment. The majority of patients require long-term therapy to maintain a response and to prevent relapse.

    The present study aims to evaluate cognitive tolerability profile of SSRIs in long-term treatment. The secondary aim is to explore differences of side effects profile between patients with major depression (MD) and anxiety disorders (AD). Sixty-seven consecutive patients, successfully treated with SSRIs in monotherapy for at least six months for MD or AD, were assessed for side effects, with a special focus on cognition. Over 20% of MD and AD patients in long term treatment with SSRIs reported cognitive symptoms including fatigue, inattentiveness, lack of concentration, memory impairment and apathy. Recall memory impairment, attention deficit and somnolence were most frequently rated as moderate or severe. There were no significant differences in SSRI cognitive side effects profile between MD and AD patients. Subjective measure of cognitive functioning, limited sample size, lack of a control group. A large proportion of depressed and anxious patients treated successfully with SSRIs for over six months reported cognitive, affective, motivational symptoms. These symptoms are likely to represent SSRI side effects rather than residual depressive symptomatology. Copyright © 2014 Elsevier B.V. All rights reserved.

    Depression is a predictor of poor prognosis in patients with heart failure. Selective serotonin (5-HT) reuptake inhibitors (SSRIs) may improve these outcomes. Left ventricular volume overload induced hypertrophy that is associated with aortic regurgitation (AR) leads to ventricular dysfunction and heart failure. The aim of this study was to verify the effects of the SSRI paroxetine on cardiac function, as well as on fluid intake and excretion, in subchronic AR. Male Wistar rats (260 to 280g) received sham (SH) surgery or AR induced by retrograde puncture of the aortic valve leaflets. The presence of AR was confirmed by echocardiography (ECHO) exams. Four weeks after AR surgery, subcutaneous injections of paroxetine (PAR: 10mg/kg 3 times in a week) or saline were administered. The rats were randomly divided into the following 4 groups and treated for 4 weeks: AR-PAR, ARsaline, SH-PAR and SH-saline. At the end of the treatment period, fractional shortening was preserved in AR-PAR, compared to AR-saline (46.6±2.7% vs 38.3±2.2%, respectively). Daily 0.3 M NaCl intake was reduced in PAR-treated rats. Natriuresis was increased in weeks 2-3 after PAR treatment. Our results suggest that augmentation of central 5-HT neurotransmission has a beneficial effect on cardiovascular remodeling following volume overload. The mechanisms underlying this effect are unknown.

    SUMMARY A total of 90 patients including 30 patients of generalized anxiety disorder and 30 of dysthymic disorder according to DSM III criteria plus 30 patients of mixed anxiety-depressive disorder were given a detailed psychiatric evaluation and four rating scales were made for measuring the level of anxiety and depression at intake and to record their improvement with treatment. Half the subjects in each group were randomly selected for treatment with imipramine and the other half with diazepam. Imipramine and diazepam were found to be equally effective (62.8% vs 62.2%) in reducing anxiety in all subjects. Imipramine was significantly better than diazepam in reducing the level of depression in the depressed group but as effective as diazepam in the other two groups. Imipramine was significantly better for the symptoms of ‘depressed mood’ and ‘retardation’, while diazepam was better in the symptom of ‘fears’. None of the other symptoms was discriminatory.

    Due to the rarity of the condition, large and prospective series defining the optimal method of digestive arteries revascularization, for the treatment of chronic intestinal ischemia, are lacking. The aim of this consecutive sample clinical study was to test the hypothesis that flexible application of different revascularization methods, according to individual cases, will yield the best results in the management of chronic intestinal ischemia. Eleven patients, of a mean age of 57 years, underwent revascularization of 11 digestive arteries for symptomatic chronic mesenteric occlusive disease. Eleven superior mesenteric arteries and one celiac axis were revascularized. The revascularization techniques included retrograde bypass grafting in 7 cases, antegrade bypass grafting in 2, percutaneous arterial angioplasty in 1, and arterial reimplantation in one case. The donor axis for either reimplantation or bypass grafting was the infrarenal aorta in 4 cases, an infrarenal Dacron graft in 4, and the celiac aorta in one case. Grafting materials included 5 polytetrafluoroethylene (PTFE) and 3 Dacron grafts. Concomitant procedures included 3 aorto-ilio-femoral grafts and one renal artery revascularization. Mean follow-up length was 31 months. There was no operative mortality. Cumulative survival rate was 88.9% at 36 months (SE 12.1%). Primary patency rate was 90% at 36 months (SE 11.6%). The symptom free rate was 90% at 36 months (SE 11.6%). Direct reimplantation, antegrade and retrograde bypass grafting, all allow good mid-term results: the choice of the optimal method depends on the anatomic and general patients status. Associated infrarenal and renal arterial lesions can be safely treated in the same time of digestive revascularization. Angioplasty alone yields poor results and should be limited to patients at poor risk for surgery.

    Full Text Available Insomnia is a disorder characterized by inability to sleep or a total lack of sleep, prevalence of which ranges from 10 to 15% among the general population with increased rates seen among older ages, female gender, White population and presence of medical or psychiatric illness. Yet this condition is still under-recognized, under-diagnosed, and under-treated. This article aims to review the operational definitions and management of chronic insomnia. A computerized search on PubMed carried from 1980 to January 2009 led to the summarization of the results. There are several strategies to manage chronic insomnia. To initiate treatment, it is necessary to define it and differentiate it from other co-morbid psychiatric disorders. Non-pharmacologic strategies such as stimulus control therapy and relaxation and cognitive therapies have the best effect sizes followed by sleep restriction, paradoxical intention and sleep hygiene education which have modest to less than modest effect sizes. Among pharmacotherapeutic agents, non-benzodiazepine hypnotics are the first line of management followed by benzodiazepines, amitryptiline and antihistaminics. However, adequate trials of combined behavior therapy and pharmacotherapy are the best course of management.

    Full Text Available Although antidepressants are generally effective in the treatment of major depressive disorder (MDD, it can still take weeks before patients feel the full antidepressant effects. Despite the efficacy of standard treatments, approximately two-thirds of patients with MDD fail to respond to pharmacotherapy. Therefore, the identification of blood biomarkers that can predict the treatment response to antidepressants would be highly useful in order to improve this situation. This article discusses inflammatory molecules as predictive biomarkers for antidepressant responses to several classes of antidepressants, including the N-methyl-d-aspartate (NMDA receptor antagonist ketamine.

    Neuropathic pain (NP) is a chronic condition that has human, social, and economic consequences. A variety of agents can be used for treatment; however, antidepressants and anticonvulsants are the 2 classes most widely studied and represent first-line agents in the management of NP. Little information is known about the adherence patterns of these medications during the first year of therapy in patients with NP. To examine the compliance and persistence of antidepressants versus anticonvulsants in patients with NP during the first year of therapy. Using electronic medical and pharmacy data for the Kaiser Permanente Southern California region, the adherence patterns for patients with a NP diagnosis prescribed an antidepressant or an anticonvulsant were studied. Compliance and persistence were measured using the medication possession ratio and the Refill-Sequence model, respectively. The study included 1817 patients with NP diagnosis taking either an antidepressant or an anticonvulsant. Within the antidepressant group, 42.9% were considered compliant, compared with 43.7% in the anticonvulsant group. Subanalysis of the 2 cohorts revealed that patients on venlafaxine were the most compliant (69.4%) compared with patients taking gabapentin (44.4%) and tricyclic antidepressants (41.8%) (Panticonvulsant group were considered persistent with their medication refills. Compliance and persistence rates were similar for patients with NP diagnosis taking antidepressants and anticonvulsants. Higher compliance was observed among patients taking venlafaxine; however, this population did have a small sample size.

    Full Text Available Marco Antonioli, Joanna Rybka, LA CarvalhoPsychoimmunology Translational Laboratory, Health Science Research Centre, Roehampton University, London, UKAbstract: Antidepressant pharmacotherapy is to date the most often used treatment for depression, but the exact mechanism of action underlying its therapeutic effect is still unclear. Many theories have been put forward to account for depression, as well as antidepressant activity, but none of them is exhaustive. Neuroimmune endocrine impairment is found in depressed patients; high levels of circulating corticosteroids along with hyperactivation of the immune system, high levels of proinflammatory cytokines, low levels of melatonin in plasma and urine, and disentrainment of circadian rhythms have been demonstrated. Moreover, antidepressant treatment seems to correct or at least to interfere with these alterations. In this review, we summarize the complex neuroimmune endocrine and chronobiological alterations found in patients with depression and how these systems interact with each other. We also explain how antidepressant therapy can modify these systems, along with some possible mechanisms of action shown in animal and human models.Keywords: antidepressant agents, biological markers, human, cytokines, neuroinflammation, psychoneuroimmunology, endophenotype

  19. Neurobiology of stress, depression, and rapid acting antidepressants: remodeling synaptic connections.

    Science.gov (United States)

    Duman, Ronald S

    2014-04-01

    Stress and depression are associated with atrophy and loss of neurons in limbic and cortical brain regions that could contribute to the symptoms of depression. Typical monoamine reuptake inhibitor antidepressants have only modest efficacy and require long-term treatment, and are only weakly effective in blocking or reversing these structural changes caused by stress. Recent findings demonstrate that ketamine, an NMDA receptor antagonist, produces rapid antidepressant actions in difficult to treat depressed patients. In addition, preclinical studies demonstrate that ketamine rapidly increases synaptic connections in the prefrontal cortex by increasing glutamate signaling and activation of pathways that control the synthesis of synaptic proteins. Moreover, ketamine rapidly reverses the synaptic deficits caused by exposure to chronic stress in rodent models. Studies of the signaling mechanisms underlying the actions of ketamine have provided novel approaches and targets for new rapid acting antidepressants with decreased side effects, as well as a better understanding of the neurobiology of stress, depression, and treatment response.

    Context Cognitive impairment in late-life depression is a core feature of the illness. Objective to test whether donepezil + antidepressant is superior to placebo + antidepressant in (1) improving cognitive performance and instrumental activities of daily living and (2) reducing recurrences of depression over two years of maintenance treatment. Design Randomized, double-blind, placebo controlled maintenance trial. Setting university clinic Main Outcome Measures global neuropsychological performance, cognitive instrumental ADL, and recurrent depression. Results Donepezil + antidepressant temporarily improved global cognition (treatment by time interaction F = 3.78, df = 2, 126, p = .03), but effect sizes were small (Cohen’s d = 0.27: group difference at 1 year). A marginal benefit to cognitive instrumental ADL was also observed (treatment by time interaction; F = 2.94; df = 2, 137, p = 0.06). The donepezil group was more likely to experience recurrent major depression: 35% [95% CI: 24%, 46%] versus 19% [95% CI: 9%, 29%] (log rank chi squared = 3.97, p = .05); hazard ratio = 2.09 [95% CI: 1.00, 4.41]. Post-hoc subgroup analyses showed that, of 57 participants with mild cognitive impairment, 3/30 on donepezil (10%; 95% CI: 0, 21%) and 9/27 on placebo (33%; 95% CI: 16%, 51%) converted to dementia over two years (Fisher exact p = 0.05). The MCI subgroup had a 44 percent recurrence rate of major depression on donepezil verses 12% on placebo (LR=4.91, p=.03). The subgroup with normal cognition (n = 73) showed no benefit on donepezil or increase in recurrence of major depression. Conclusion Whether ChEI should be used as augmentation in the maintenance treatment of late-life depression depends upon a careful weighing of risks and benefits in those with MCI. In cognitively intact patients, donepezil appears to have no clear benefit for preventing progression to MCI/dementia or recurrence of depression. PMID:21199965

  1. Effects of chronic treatment with corticosterone and imipramine on fos immunoreactivity and adult hippocampal neurogenesis.

    In a previous study we showed that rats chronically treated with corticosterone (CORT) display anxiogenic behavior, evidenced by facilitation of avoidance responses in the elevated T-maze (ETM) model of anxiety. Treatment with the tricyclic antidepressant imipramine significantly reversed the anxiogenic effects of CORT, while inhibiting ETM escape, a response related to panic disorder. To better understand the neurobiological mechanisms underlying these behavioral effects, analysis of c-fos protein immunoreactivity (fos-ir) was used here to map areas activated by chronic CORT (200 mg pellets, 21-day release) and imipramine (15 mg/kg, IP) administration. We also evaluated the number of cells expressing the neurogenesis marker doublecortin (DCX) in the hippocampus and measured plasma CORT levels on the 21st day of treatment. Results showed that CORT increased fos-ir in the ventrolateral septum, medial amygdala and paraventricular hypothalamic nucleus and decreased fos-ir in the lateral periaqueductal gray. Imipramine, on the other hand, increased fos-ir in the medial amygdala and decreased fos-ir in the anterior hypothalamus. CORT also decreased the number of DCX-positive cells in the ventral and dorsal hippocampus, an effect antagonized by imipramine. CORT levels were significantly higher after treatment. These data suggest that the behavioral effects of CORT and imipramine are mediated through specific, at times overlapping, neuronal circuits, which might be of relevance to a better understanding of the physiopathology of generalized anxiety and panic disorder.

    Full Text Available Abstract Background Fibromyalgia (FM is characterized by chronic widespread pain, which is often refractory to conventional painkillers. Numerous clinical studies have demonstrated that antidepressants are effective in treating FM pain. We previously established a mouse model of FM-like pain, induced by intermittent cold stress (ICS. Results In this study, we find that ICS exposure causes a transient increase in plasma corticosterone concentration, but not in anxiety or depression-like behaviors. A single intrathecal injection of an antidepressant, such as milnacipran, amitriptyline, mianserin or paroxetine, had an acute analgesic effect on ICS-induced thermal hyperalgesia at post-stress day 1 in a dose-dependent manner. In addition, repeated daily antidepressant treatments during post-stress days 1-5 gradually reversed the reduction in thermal pain threshold, and this recovery was maintained for at least 7 days after the final treatment. In addition, relief from mechanical allodynia, induced by ICS exposure, was also observed at day 9 after the cessation of antidepressant treatment. In contrast, the intravenous administration of these antidepressants at conventional doses failed to provide relief. Conclusions These results suggest that the repetitive intrathecal administration of antidepressants permanently cures ICS-induced FM pain in mice.

    The aim of this study was to investigate if biomarkers in QEEG, genetic and neuropsychological measures are suitable for the prediction of antidepressant treatment outcome in depression. Twenty-five patients diagnosed with major depressive disorder were assessed twice, pretreatment and at 8-wk follow-up, on a variety of QEEG and neuropsychological tasks. Additionally, cheek swab samples were collected to assess genetic predictors of treatment outcome. The primary outcome measure was the absolute decrease on the HAM-D rating scale. Regression models were built in order to investigate which markers contribute most to the decrease in absolute HAM-D scores. Patients who had a better clinical outcome were characterized by a decrease in the amplitude of the Auditory Oddball N1 at baseline. The 'Met/Met' variant of the COMT gene was the best genetic predictor of treatment outcome. Impaired verbal memory performance was the best cognitive predictor. Raised frontal Theta power was the best EEG predictor of change in HAM-D scores. A tentative integrative model showed that a combination of N1 amplitude at Pz and verbal memory performance accounted for the largest part of the explained variance. These markers may serve as new biomarkers suitable for the prediction of antidepressant treatment outcome.

    It has been hypothesized that non-rapid eye movement (NREM) sleep facilitates declarative memory consolidation, and rapid eye movement (REM) sleep is particularly important in promoting procedural learning. The aim of this study was to examine the effects of pharmacological REM sleep suppression on performance in different neuropsychological tasks. For our baseline, we chose 41 moderately depressed patients (age range 19-44 years), who were not taking antidepressants. In the morning after polysomnography, we tested memory recall and cognitive flexibility by assessment of verbal and figural fluency, a shift of attention task and the Trail Making Test B. After recording baseline values, patients were assigned randomly to one of three treatment groups: medication with citalopram; medication with reboxetine; or exclusive treatment with psychotherapy. Retesting took place 1 week after onset of treatment. The main results were: (1) an association of slow-wave sleep with verbal memory performance at baseline; (2) a suppression of REM sleep in patients taking citalopram and reboxetine; (3) no differences regarding neuropsychological performance within the treatment groups; and (4) no association of REM sleep diminution with decreases in memory performance or cognitive flexibility in patients treated with citalopram or reboxetine. In line with other studies, our results suggest that there are no negative effects of a decrease in REM sleep on memory performance in patients taking antidepressants.

    2016-01-01

    Systemic arterial hypertension (SAH) is a progressive cardiovascular syndrome caused by complex and interrelated causes. The early markers of this syndrome are often present even before the blood pressure (BP) elevation; therefore, SAH cannot only be classified by the BP elevation threshold, which sometimes is discreet. Its progression is strongly associated with structural and functional cardiovascular abnormalities, which lead to end-organ damage (heart, kidney, brain, blood vessels and other organs), and cause premature morbidity and death. In this sense, the BP is only a biomarker of this cardiovascular syndrome, which is why it is more useful to consider individual BP patterns of the ill patient rather than a single BP threshold. The study and treatment of hypertension in chronic kidney disease (CKD) has made some progresses, especially in patients requiring dialysis. The use of non-invasive technology to register the BP has reconfigured health care of patients in regards to the diagnosis, circadian pattern, clinical surveillance, pharmacological prescription, prognosis, and risk of cardiovascular events (as well as mortality). The opportunity in the diagnosis and treatment means a delay in the onset of complications and, also, of dialysis. The blockade of the renin-aldotensin-aldosterone system (RAAS), a regular monitoring of the dry weight of the population in dialysis, and non-pharmacological interventions to modify lifestyle are the maneuvers with greater impact on the morbidity and mortality of patients.

  8. Pegloticase: in treatment-refractory chronic gout.

    2011-11-12

    Intravenous pegloticase offers a novel approach to treating chronic gout refractory to conventional therapy. Pegloticase is a recombinant polyethylene glycol-conjugated form of uricase (a uric acid-specific enzyme lacking in humans) that catalyses the oxidation of uric acid to allantoin. In randomized, placebo-controlled, double-blind, 6-month, phase III trials, intravenous pegloticase 8 mg every 2 or 4 weeks provided sustained reductions in plasma uric acid levels to less than the therapeutic target of 6 mg/dL in a substantial proportion of patients with chronic gout who were refractory to, or intolerant of, conventional urate-lowering therapy. Pegloticase 8 mg every 2 weeks was associated with disease-modifying benefits relative to placebo, as shown by significant improvements from baseline in tophi resolution, frequency of gout flares and tender joint count, and clinically relevant and statistically significant improvements from baseline in health-related quality-of-life parameters related to disability, pain and physical function. Pegloticase 8 mg every 4 weeks was also significantly more effective than placebo with regard to most, but not all, of these endpoints. Preliminary data from an open-label extension of the phase III trials indicate that long-term treatment with pegloticase 8 mg every 2 or 4 weeks may maintain plasma uric acid normalization in patients who experienced a sustained uric acid response during the phase III trials. The most common serious adverse events associated with pegloticase are gout flares, infusion reactions and anaphylaxis. In addition, exacerbation of pre-existing congestive heart failure was reported in 2% of patients receiving pegloticase 8 mg every 2 weeks in the phase III trials.

    Ginsenosides Rg1,Rb1,R1,Rd,and Re are major constituents of Panax notoginseng,a famous traditional Chinese medicinal herb,which has both stimulative and inhibitory effects on the central nervous system (CNS).The monoamine hypothesis proposes that depression is a result of the depletion of 5-hydroxytryptamine (5-HT),norepinephrine (NE) and dopamine (DA) in addition to the activation of monoamine oxidase in the CNS.The purpose of this study was to determine whether P.notoginseng Saponin (PNS) has an antidepressant activity.We investigated the antidepressant-like activities of Rg1,Rb1,R1,Rd,and Re in mice,using two animal models of depression.In addition,we analyzed the neurochemicals by the chronic unpredictable mild stress test.Our results showed that Rb 1,Rd,and Re treatment at 10 mg kg-1 significantly reduced the duration of immobility in both the tail suspension and forced swimming tests.Rb1,Rd,and Re increases in 5HT and NE levels at 10 mg kg-1 in both the frontal cortex and hippocampus.Dopamine levels increased in the hippocampus and the striatum.Moreover,5-hydroxyindoleacetic acid (5-HIAA) levels were found increased in the hippocampus.These findings suggest that the antidepressant effects of Rb1,Rd,and Re may be related to the increase in 5-HT and NE in the CNS,and through the alterations in the synthesis or metabolism of dopamine.

    Full Text Available Philippe CourtetCHRU Montpellier, Inserm U888, University of Montpellier I, Montpellier, FranceAbstract: Suicidal behavior (SB represents a major public health issue. Clinical and basic research suggests that SB is a specific entity in psychiatric nosology involving a combination of personality traits, genetic factors, childhood abuse and neuroanatomical abnormalities. The principal risk factor for suicide is depression. More than 60% of patients who complete suicide are depressed at the time of suicide, most of them untreated. There has been a controversy concerning a possible increased risk of SB in some depressed patients treated with antidepressants. Most recent evidence suggests, however, that treatment of depressed patients is associated with a favorable benefit-risk ratio. A recent study has determined the effects of 6 weeks of antidepressant treatment with the serotonin and norepinephrine reuptake inhibitor, milnacipran, on suicidality in a cohort of 30 patients with mild to moderate depression. At baseline, mild suicidal thoughts were present in 46.7% of patients. Suicidal thoughts decreased progressively throughout the study in parallel with other depressive symptoms and were essentially absent at the end of the study. At no time during treatment was there any indication of an increased suicidal risk. Retardation and psychic anxiety decreased in parallel possibly explaining the lack of any “activation syndrome” in this study.Keywords: suicide, milnacipran, SNRI, activation syndrome

    Novel hypotheses suggest that antidepressants, such as the selective serotonin reuptake inhibitor fluoxetine, induce neuronal structural plasticity, resembling that of the juvenile brain, although the underlying mechanisms of this reopening of the critical periods still remain unclear. However, recent studies suggest that inhibitory networks play an important role in this structural plasticity induced by fluoxetine. For this reason we have analysed the effects of a chronic fluoxetine treatment in the hippocampus and medial prefrontal cortex (mPFC) of transgenic mice displaying eGFP labelled interneurons. We have found an increase in the expression of molecules related to critical period plasticity, such as the polysialylated form of the neural cell adhesion molecule (PSA-NCAM), GAD67/65 and synaptophysin, as well as a reduction in the number of parvalbumin expressing interneurons surrounded by perineuronal nets. We have also described a trend towards decrease in the perisomatic inhibitory puncta on pyramidal neurons in the mPFC and an increase in the density of inhibitory puncta on eGFP interneurons. Finally, we have found that chronic fluoxetine treatment affects the structure of interneurons in the mPFC, increasing their dendritic spine density. The present study provides evidence indicating that fluoxetine promotes structural changes in the inhibitory neurons of the adult cerebral cortex, probably through alterations in plasticity-related molecules of neurons or the extracellular matrix surrounding them, which are present in interneurons and are known to be crucial for the development of the critical periods of plasticity in the juvenile brain.

    Background Co-occurring cognitive impairment in geriatric depression may not improve with antidepressant treatment and it may progress to dementia. Aim Assess the relationship between changes in cognitive and depressive symptoms among patients with geriatric depression and their association with the APOE epsilon 4 allele before and after antidepressant treatment. Methods The presence of the APOE epsilon 4 allele was assessed in 64 incident cases of geriatric depression and 31 elderly individuals without depression and the Geriatric Depression Scale (GDS), Mini-Mental State Examination (MMSE), digit span test, and Trail Making Tests A and B (TMT-A, TMT-B) were administered to these subjects at baseline and 12 months after baseline, during which time the depressed group received standardized treatment with selective serotonin reuptake inhibitors (SSRIs). Results Prior to treatment patients with geriatric depression had significantly worse cognitive functioning than control subjects and 31 (48%) met criteria for mild cognitive impairment (MCI). After treatment depressed patients with and without comorbid MCI both had significant improvements in their depressive and cognitive symptoms, but those with MCI had more residual symptoms. The severity of cognitive symptoms was not associated with the severity of depressive symptoms at baseline, but they were positively correlated at the 12-month follow-up. The APOE epsilon 4 allele was identified in 14% (9/64) of the patients and in 3% (1/31) of the controls (Fisher's Exact Test, p=0.158). Compared to depressed patients without the allele, depressed patients with the allele had more severe cognitive deficits both before and after treatment, though only some of these differences were statistically significant. Conclusions There is substantial cognitive impairment in elderly individuals with geriatric depression. Both the depressive and cognitive symptoms improve with standard SSRI treatment, but individuals with comorbid MCI

    Chronic heart failure is a common and complex clinical syndrome that results from impaired cardiac relaxation or contraction. There have been considerable advances in the management of chronic heart failure; however, the mortality rate remains high. Patients with chronic heart failure may experience multiple debilitating symptoms, such as fatigue, pain, and peripheral oedema. However, breathlessness may be considered the most debilitating symptom. The management of chronic heart failure aims to improve the patient's quality of life by reducing symptoms and supporting the patient to manage their condition. Treatment of patients with chronic heart failure may involve a combination of pharmacological therapy, device implantation and cardiac rehabilitation. This is the second of two articles on chronic heart failure. Part 1 discussed the pathophysiology of chronic heart failure, its causes, assessment, signs and symptoms. Part 2 outlines the treatment and management of patients with the condition, including pharmacological strategies, device implantation, lifestyle modification, cardiac rehabilitation and palliative care.

    Full Text Available OBJECTIVE: To determine the impact of periodontal treatment on serum levels of prohepcidin (the prohormone of hepcidin and systemic inflammation markers, as well as correlations among these markers, in patients with chronic periodontitis and chronic kidney disease who were not undergoing dialysis. METHODS: We included 56 chronic periodontitis patients, 36 with chronic kidney disease and 20 without systemic diseases and with normal renal function (control group. Chronic kidney disease was defined as suggested by the clinical practice guidelines in the National Kidney Foundation. Chronic periodontitis was defined through clinical attachment level and by probing pocket depth, according to the American Association of Periodontology. The inflammatory markers ultrasensitive C-reactive protein, interleukin-6, and prohepcidin were evaluated before and 3 months after periodontal treatment. RESULTS: The efficacy of periodontal treatment was confirmed by the improvement in clinical parameters of chronic periodontitis in the control and chronic kidney disease groups. Periodontal treatment resulted in significant reductions in ultrasensitive C-reactive protein, interleukin-6 and serum prohepcidin levels in both groups. Moreover, in multivariate linear regression, the reduction in prohepcidin after periodontal treatment was significantly and independently associated with interleukin-6 levels in the control group. CONCLUSIONS: By inducing a decline in the systemic inflammatory response and a decrease in serum prohepcidin, successful periodontal treatment may represent an important means of ameliorating the inflammatory burden seen in patients with chronic kidney disease.

    Many studies suggest that the prefrontal cortex (PFC) is a target limbic region for stress response because a dysfunction here is linked to anhedonia, a decrease in reactivity to rewards, and to anxiety. It is suggested that stress-induced persistent molecular changes in this brain region could bring some light on the mechanisms perpetuating depressive episodes. In order to address this issue, here we have studied the long-term PFC gene expression pattern and behavioral effects induced by a chronic mild stress (CMS) model and antidepressant treatment in mice. CMS was applied to mice for six weeks and imipramine (10mg/kg, i.p.) or saline treatment was administered for five weeks starting from the third week of CMS. Mice were sacrificed one month after CMS and following two weeks after the discontinuation of drug treatment and the PFC was dissected and prepared for gene (mRNA) and protein expression studies. Using the same experimental design, a separate group of mice was tested for anhedonia, recognition memory, social interaction and anxiety. CMS induced a long-term altered gene expression profile in the PFC that was partially reverted by imipramine. Specifically, the circadian rhythm signaling pathway and functions such as gene expression, cell proliferation, survival and apoptosis as well as neurological and psychiatric disorders were affected. Of these, some changes of the circadian rhythm pathway (Hdac5, Per1, and Per2) were validated by RT-PCR and western-blot. Moreover, CMS induced long-lasting anhedonia that was reverted by imipramine treatment. Impaired memory, decreased social interaction and anxiety behavior were also induced by chronic stress. We have identified in the PFC molecular targets oppositely regulated by CMS and imipramine that could be relevant for chronic depression and antidepressant action. Among these, a possible candidate for further investigation could be the circadian rhythm pathway.

    BACKGROUND: Some patients with chronic pancreatitis (CP) may require surgery mainly because of intractable pain, suspicion of malignancy, or complications related to CP. This study aimed to analyze the efifcacy of surgical treatment for patients with CP in terms of pain relief, control of local complications, and pancreatic endocrine/exocrine function. METHODS: Twenty-six patients with CP were treated surgically at our hospital from June 1985 to November 2005. The clinical data of these patients were analyzed retrospectively. RESULTS:  The follow-up time ranged from 8 to 130 months with a median of 60.6 months. No patients were lost to follow-up. All patients had improvement of clinical symptoms such as abdominal pain, steatorrhea and weight loss, to some degree, especially pain relief in patients with good dilation and high pressure of the main pancreatic duct. The endocrine and exocrine functions were not alleviated in all patients, otherwise the impaired glucose tolerance was improved in 8 (30.8%), 15 (57.7%) maintained the same body weight, one (3.8%) had an acute attack of CP, and 2 (7.7%) developed pancreatic carcinoma in the 16th and 28th month postoperatively and died within 3 years after operation for CP. The 1-, 3-, 5-year pain-free rates of CP patients were 96.2%(25/26), 88.5%(23/26) and 84.6%(22/26), respectively. CONCLUSIONS: In selected patients with CP, surgical treatment is a safe procedure and can effectively relieve pain and control local complications;also, it is helpful to improve the quality of life for patients with pancreatitis, and to control the development of this disease.

  5. Current treatment in chronic obstructive pulmonary disease

    Chronic obstructive pulmonary disease (COPD) is defined by fixed airflow limitation associated with an abnormal pulmonary and systemic inflammatory response of the lungs to cigarette smoke. COPD represents an increasing burden worldwide, reported to be the sixth leading cause of death in 1990 and the fourth in 2000. Discouragingly, it is projected to jump to third place by the year 2020.There is increasing evidence that COPD is a more complex systemic disease than an airway and lung disease. In particular, cachexia, skeletal muscle abnormalities, diabetes, coronary artery disease, heart failure, cancer and pulmonary vascular disease are the most common comorbidities. It is associated with a wide variety of systemic consequences, most notably systemic inflammation. Because COPD patients have in general ahigher cardiovascular risk than the average population, cardiovascular safety in a COPD medication is of critical importance.SINGH et al performed a systematic review and recta-analysis of 17 clinical trials enrolling 14 783 patients treated with inhaled anticholinergic drugs used for the treatment of COPD. Inhaled anticholinergics significantly increased the risk of cardiovascular death, MI, or stroke ( 1.8 % vs 1.2 % for control; RR, 1.58 (95 % CI,1.21 - 2.06); P < 0.001 ). However, UPLIIFT (Understanding the Potential Long-Term Impacts on Function with Tiotropium) , a large, 4-year, placebo controlled clinical trial with tiotropium in approximately 6 000 patients with COPD. The preliminary results of UPLIFT showed that there was no increased risk of stroke with tiotropium bromide compared to placebo.A meta-analysis is always considered less convincing than a large prospective trial designed to assess the outcome of interest. However, COPD is a systemic disease. COPD management needs to focus on four major areas: smoking cessation, pharmacologic therapy, exercise training, and pulmonary rehabilitation. Clinicians and patients should always carefully consider any

  6. Effective physical treatment for chronic low back pain.

    It is now feasible to adopt an evidence-based approach when providing physical treatment for patients with chronic LBP. A summary of the efficacy of a range of physical treatments is provided in Table 1. The evidence-based primary care options are exercise, laser, massage, and spinal manipulation; however, the latter three have small or transient effects that limit their value as therapies for chronic LBP. In contrast, exercise produces large reductions in pain and disability, a feature that suggests that exercise should play a major role in the management of chronic LBP. Physical treatments, such as acupuncture, backschool, hydrotherapy, lumbar supports, magnets, TENS, traction, ultrasound, Pilates therapy, Feldenkrais therapy, Alexander technique, and craniosacral therapy are either of unknown value or ineffective and so should not be considered. Outside of primary care, multidisciplinary treatment or functional restoration is effective; however, the high cost probably means that these programs should be reserved for patients who do not respond to cheaper treatment options for chronic LBP. Although there are now effective treatment options for chronic LBP, it needs to be acknowledged that the problem of chronic LBP is far from solved. Though treatments can provide marked improvements in the patient's condition, the available evidence suggests that the typical chronic LBP patient is left with some residual pain and disability. Developing new, more powerful treatments and refining the current group of known effective treatments is the challenge for the future.

    Apoptosis or programmed cell death is a critical regulator of tissue homeostasis and emerging evidence is focused on the role of apoptosis mechanisms in the central nervous system. Generally, apoptosis is necessary to prevent cancerous growths. However, excessive apoptosis in post-mitotic cells such as neurons leads to neurodegeneration. Chronic stress, which can precipitate depression, has been shown to increase the susceptibility of certain populations of neurons to cell death while antidepressant treatment, in general, shows the ability to oppose these effects and promote neuroprotection. Here, we discuss the major players in cell death pathways, the physiological implications of chronic stress and depression, chronic stress models in animals which result in cell death and the different classes of antidepressants and mood stabilizers that have been shown to prevent cell death. We discuss the cellular effects of antidepressants and possible modes of action in preventing apoptosis. Investigations on the role of apoptosis in mediating the molecular, physiological and behavioural effects of antidepressants may help gain a better mechanistic insight into drug action and allow refinement of current therapeutics in order to target these pathways in a specific manner.

    In the rat forced swimming test (FST), reuptake inhibitors selective of either serotonin (5-HT) or noradrenaline (NA) decrease immobility duration, and increase, respectively, swimming and climbing behaviour. In this study, an almost total 6-OHDA-induced NA-depletion prevented the behavioural effects of desipramine, but not fluoxetine. Interestingly, the serotonin/noradrenaline-reuptake-inhibitor milnacipran, as well as a (desipramine+fluoxetine) combination, could produce both swimming and climbing behaviour in NA-lesioned rats, but not in non-lesioned. The new antidepressant mirtazapine, which enhances both 5-HT and NA transmissions, supposedly through the antagonizing of alpha(2)-adrenoreceptors, dose-dependently reduced immobility and increased climbing behaviour. Interestingly, a (mirtazapine+fluoxetine) combination treatment resulted in additive anti-immobility effects and in the summation of fluoxetine-induced swimming with mirtazapine-induced climbing. Taken together, these data suggest that the NA system mediates presynaptic inhibiting interactions on the 5-HT system, that may involve alpha(2)-receptors, and that may limit the efficacy of mixed serotonin/noradrenaline reuptake inhibition in subacute antidepressant treatments.

    Evidence from previous studies suggests that heart rate variability (HRV) is reduced in major depressive disorder (MDD). However, whether this reduction is attributable to the disorder per se or to medication, since antidepressants may also affect HRV, is still debated. There is a dearth of information regarding the effects of agomelatine, a novel antidepressant, on HRV. Here, we investigated whether HRV is reduced in MDD and compared the effects of agomelatine and paroxetine on HRV. We recruited 618 physically healthy unmedicated patients with MDD and 506 healthy volunteers aged 20-65 years. Frequency-domain measures of resting HRV were obtained at the time of enrollment for all participants. For patients with MDD, these measures were obtained again after 6 weeks of either agomelatine or paroxetine monotherapy. Compared with healthy subjects, unmedicated patients with MDD exhibited significantly lower variance (total HRV), low frequency (LF), and high frequency (HF) HRV, and a higher LF/HF ratio. Depression severity independently contributed to decreased HRV and vagal tone. Fifty-six patients completed the open-label trial (n=29 for agomelatine, n=27 for paroxetine). Between-group analyses showed a significant group-by-time interaction for LF-HRV and HF-HRV, driven by increases in LF-HRV and HF-HRV only after agomelatine treatment. Within the paroxetine-treated group, there were no significant changes in mean R-R intervals or any HRV indices. We therefore concluded that MDD is associated with reduced HRV, which is inversely related to depression severity. Compared with paroxetine, agomelatine has a more vagotonic effect, suggesting greater cardiovascular safety. Clinicians should consider HRV effects while selecting antidepressants especially for depressed patients who already have decreased cardiac vagal tone. Copyright © 2015 Elsevier Inc.

    Interferon-alpha (IFN-alpha), though widely used for the treatment of chronic viral hepatitis, may be associated with the occurrence of autoimmune disorders. In this case report, a patient with chronic hepatitis C virus infection had chronic inflammatory demyelinating polyneuropathy (CIDP) after the initiation of IFN-alpha therapy. The neurological symptoms of this patient continued to progress even though the treatment with IFN-alpha had been withdrawn; the symptoms improved dramatically following treatment with intravenous immunoglobulin. This case may therefore provide an important clue to understand the immune mechanism of CIDP and IFN-alpha.

    Full Text Available Background. There is evidence supporting the effectiveness of psychoeducation (PE in patients with symptoms of depression in primary care (PC, but very few studies have assessed this intervention in antidepressant-naïve patients. The aim of this study is to assess the effectiveness of a PE program in these patients, since the use of antidepressant (AD medication may interfere with the effects of the intervention. Methods. 106 participants were included, 50 from the PE program (12 weekly 1.5-hour sessions and 56 from the control group (CG that received the usual care. Patients were assessed at baseline and at 3, 6, and 9 months. The main outcome measures were the Beck Depression Inventory (BDI and remission based on the BDI. The analysis was carried out on an intention-to-treat basis. Results. The PE program group showed remission of symptoms of 40% (P=0.001 posttreatment and 42% (P=0.012 at 6 months. The analysis only showed significant differences in the BDI score posttreatment (P=0.008; effect size Cohen’s d′=0.55. Conclusions. The PE intervention is an effective treatment in the depressive population not treated with AD medication. Before taking an AD, psychoeducational intervention should be considered.

    Brain-derived neurotrophic factor (BDNF) plays a key role in the regulation of depression in the brain. Recently, increasing studies have focused on the antidepressant-like mechanism of BDNF and its downstream signaling pathway. A previous study has shown that asiaticoside produced an antidepressant-like action in the mouse tail suspension test and forced swimming test. However, the neurotrophic mechanism that is affected by asiaticoside is unclear. Our present study aimed to verify whether asiaticoside produces an antidepressant-like effect through the activation of BDNF signaling in chronic unpredictable mild stress (CUMS). The results showed that mice treated with asiaticoside for four weeks reversed the decreased sucrose preference and increased immobility time that was observed in CUMS mice. In addition, we found that asiaticoside up-regulated BDNF, PSD-95 and synapsin I expression only in the hippocampus but not in the frontal cortex in both non-stressed and CUMS mice. However, K252a, an inhibitor of BDNF receptor tropomyosin-related kinase receptor B (TrkB), completely abolished the antidepressant-like effect of asiaticoside. Moreover, the expression of hippocampal BDNF, PSD-95 and synapsin I that had increased with asiaticoside also declined with K252a pretreatment. In conclusion, our study implies that it is possible that asiaticoside exerts its antidepressant-like action by activating BDNF signaling in the hippocampus.

    Background: The impact of psychotropic drug choice upon admissions for schizophrenia is not well understood. Aims: To examine the association between antipsychotic/antidepressant use and time in hospital for patients with schizophrenia. Methods: We conducted an observational study, using 8 years’ admission records and electronically generated drug histories from an institution providing secondary mental health care in Cambridgeshire, UK, covering the period 2005–2012 inclusive. Patients with a coded ICD-10 diagnosis of schizophrenia were selected. The primary outcome measure was the time spent as an inpatient in a psychiatric unit. Antipsychotic and antidepressant drugs used by at least 5% of patients overall were examined for associations with admissions. Periods before and after drug commencement were compared for patients having pre-drug admissions, in mirror-image analyses correcting for overall admission rates. Drug use in one 6-month calendar period was used to predict admissions in the next period, across all patients, in a regression analysis accounting for the effects of all other drugs studied and for time. Results: In mirror-image analyses, sulpiride, aripiprazole, clozapine, and olanzapine were associated with fewer subsequent admission days. In regression analyses, sulpiride, mirtazapine, venlafaxine, and clozapine–aripiprazole and clozapine–amisulpride combinations were associated with fewer subsequent admission days. Conclusions: Use of these drugs was associated with fewer days in hospital. Causation is not implied and these findings require confirmation by randomized controlled trials. PMID:27336041

    Full Text Available Objective To explore the correlation of depressive symptoms to the microRNA (miRNA expression level in monocytes of patients with depression before and after antidepressant treatment. Methods Eighty-one patients with depression, admitted to the 102 Hospital of PLA from Aug. 2012 to Oct. 2013, having not received antidepressants treatment and meeting the criteria as listed in Diagnostic and Statistical Manual 4th edition (DSM-IV, were selected as case group. Eighty-one normal individuals served as control group. With Affymetrix Expression Array, 26 miRNAs were identified from 3 individuals from each group as candidate miRNA, and among them 9 miRNAs (miR-146b, miR-1972, miR-26b, miR-29b, miR-338, miR-4485, miR-4498, miR-4743 and miR-874 in monocytes were selected for quantitative real-time reverse transcription polymerase chain reaction (RTPCR assessment. Twenty patients from the case group were selected for the assessment of miRNA expression levels, and the clinical symptoms and treatment effect were evaluated using Hamilton Depression Scale (HAMD and Clinical Global Impression (CGI, before and 6 weeks after antidepressant (venlafaxine, sertraline, mirtazapine, etc. treatment. Results Compared with the control group, the expression levels of miRNA-26b, miRNA-4743, miRNA-4498, miRNA-4485 and miRNA-1972 of the case group were significantly up-regulated (P<0.05. The variance of expression level of miRNA-4743, miRNA-4498, miRNA-4485 and miRNA-1972 was respectively positively correlated with improvement in retardation factors (P<0.05, meanwhile the variance of expression level of miRNA-26b was negatively correlated with the improvement of day and night change factors (P<0.05. Logistic regression analysis demonstrated that the alteration of miRNA-4485 expression may account 28.8% of retardation variance (P<0.05. Conclusion  The miRNA-4743, miRNA-4498, miRNA-4485, miRNA-1972 and miRNA-26b in monocytes may serve as the biomarkers for the

    To assess treatment persistence, hospitalization outcomes and mean healthcare costs of geriatric major depressive disorder (MDD) patients treated with escitalopram compared to other selective serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs). Patients aged > or = 65 years with at least one inpatient claim or two independent claims associated with MDD diagnosis were identified in the IHCIS National Managed Care Database (2003-2005). Patients were continuously enrolled for at least > or = 12 months, filled at least one prescription for an SSRI/SNRI and did not use any second-generation antidepressant during the 6 months pre-index date. Unadjusted and multivariate analyses adjusting for baseline characteristics were conducted. Treatment persistence, hospitalization utilization, and average prescription drug, medical, and total healthcare costs were compared between patients initiated on escitalopram versus other SSRI/SNRIs. Escitalopram-treated patients (N = 459) were less likely to discontinue treatment (HR = 0.85, p = 0.012) or switch to another second-generation antidepressant (HR = 0.76, p = 0.006) compared to patients treated with other SSRI/SNRIs (N = 1517). Escitalopram-treated patients had 39% fewer hospitalization days (p = 0.004). Both groups had similar mean prescription drug costs ($1659 vs. $1630, p = 0.687). After controlling for baseline characteristics, escitalopram-treated patients had lower mean total medical service costs ($9425 vs. $12,703, p Geriatric patients treated with escitalopram had higher treatment persistence, fewer hospitalization days and lower total healthcare costs than patients on other SSRI/SNRIs after controlling for baseline characteristics. Most of the cost savings were due to reductions in hospitalizations.

  4. Antidepressant effects of ketamine: mechanisms underlying fast-acting novel antidepressants

    Full Text Available Newer antidepressants are needed for the many individuals with major depressive disorder that do not respond adequately to treatment and because of a delay of weeks before the emergence of therapeutic effects. Recent evidence from clinical trials shows that the NMDA antagonist ketamine is a revolutionary novel antidepressant because it acts rapidly and is effective for treatment-resistant patients. A single infusion of ketamine alleviates depressive symptoms in treatment-resistant depressed patients within hours and these effects may be sustained for up to 2 weeks. Although the discovery of ketamine’s effects has reshaped drug discovery for antidepressants, the psychotomimetic properties of this compound limit the use of this therapy to the most severely ill patients. In order to develop additional antidepressants like ketamine, adequate preclinical behavioral screening paradigms for fast-acting antidepressants need to be established and used to identify the underlying neural mechanisms. This review examines the preclinical literature attempting to model the antidepressant-like effects of ketamine. Acute administration of ketamine has produced effects in behavioral screens for antidepressants like the forced swim test, novelty suppression of feeding and in rodent models for depression. Protracted behavioral effects of ketamine have been reported to appear after a single treatment that last for days. This temporal pattern is similar to its clinical effects and may serve as a new animal paradigm for rapid antidepressant effects in humans. In addition, protracted changes in molecules mediating synaptic plasticity have been implicated in mediating the antidepressant-like behavioral effects of ketamine. Current preclinical studies are examining compounds with more specific pharmacological effects at glutamate receptors and synapses in order to develop additional rapidly acting antidepressants without the hallucinogenic side effects or abuse

    Full Text Available The treatment of young people with chronic pain is a complex endeavor. Many of these youth do not obtain adequate relief from available interventions. Psychological neuromodulatory treatments have been shown to have potential benefit for adults with chronic pain. Here, we review and summarize the available information about the efficacy of three promising psychological neuromodulatory treatments—neurofeedback, meditation and hypnosis—when provided to young people with chronic pain. A total of 16 articles were identified and reviewed. The findings from these studies show that hypnotic treatments are effective in reducing pain intensity for a variety of pediatric chronic pain problems, although research suggests variability in outcomes as a function of the specific pain problem treated. There are too few studies evaluating the efficacy of neurofeedback or meditation training in young people with chronic pain to draw firm conclusions regarding their efficacy. However, preliminary data indicate that these treatments could potentially have positive effects on a variety of outcomes (e.g., pain intensity, frequency of pain episodes, physical and psychological function, at least in the short term. Clinical trials are needed to evaluate the effects of neurofeedback and meditation training, and research is needed to identify the moderators of treatment benefits as well as better understand the mechanisms underlying the efficacy of all three of these treatments. The findings from such research could enhance overall treatment efficacy by: (1 providing an empirical basis for better patient-treatment matching; and (2 identifying specific mechanisms that could be targeted with treatment.

  7. Antidepressants: update on new agents and indications.

    2003-02-01

    A number of antidepressants have emerged in the U.S. market in the past two decades. Selective serotonin reuptake inhibitors have become the drugs of choice in the treatment of depression, and they are also effective in the treatment of obsessive-compulsive disorder, panic disorder, and social phobia. New indications for selective serotonin reuptake inhibitors include post-traumatic stress disorder, premenstrual dysphoric disorder, and generalized anxiety disorder. Extended-release venlafaxine has recently been approved by the U.S. Food and Drug Administration for the treatment of generalized anxiety disorder. Mirtazapine, which is unrelated to the selective serotonin reuptake inhibitors, is unique in its action--stimulating the release of norepinephrine and serotonin. The choice of antidepressant drug depends on the agent's pharmacologic profile, secondary actions, and tolerability. Sexual dysfunction related to the use of antidepressants may be addressed by reducing the dosage, switching to another agent, or adding another drug to overcome the sexual side effects. Augmentation with lithium or triiodothyronine may be useful in patients who are partially or totally resistant to antidepressant treatment. Finally, tapering antidepressant medication may help to avoid discontinuation syndrome or antidepressant withdrawal.

    2017-10-01

    The principle evidence that antidepressant medication (ADM) is an effective maintenance treatment for adults with major depressive disorder (MDD) is from placebo substitution trials. These trials enter responders from ADM efficacy trials into randomized, double-blind placebo-controlled (RDBPC) effectiveness trials to measure the rate of MDD relapse over time. However, other randomized maintenance trial methodologies merit consideration and comparison. A systematic review of ADM randomized maintenance trials included research reports from multiple databases. Relapse rate was the main effectiveness outcome assessed. Five ADM randomized maintenance methodologies for MDD responders are described and compared for outcome. These effectiveness trials include: placebo-substitution, ADM/placebo extension, ADM extension, ADM vs. psychotherapy, and treatment as usual. The placebo-substitution trials for those abruptly switched to placebo resulted in unusually high (46%) rates of relapse over 6-12months, twice the continuing ADM rate. These trials were characterized by selective screening, high attrition, an anxious anticipation of a switch to placebo, and a risk of drug withdrawal symptoms. Selectively screened ADM efficacy responders who entered into 4-12month extension trials experienced relapse rates averaging ~10% with a low attrition rate. Non-industry sponsored randomized trials of adults with multiple prior MDD episodes who were treated with ADM maintenance for 1-2years experienced relapse rates averaging 40%. Placebo substitution trial methodology represents only one approach to assess ADM maintenance. Antidepressant maintenance research for adults with MDD should be evaluated for industry sponsorship, attrition, the impact of the switch to placebo, and major relapse differences in MDD subpopulations.

    Psychological depression is drawing accumulating attention nowadays, due to the skyrocketing incidence worldwide and the enormous burdens it incurs. Physical exercise has been long recog-nized for its therapeutic effects on depressive disorders, although knowledge of the underlying mechanisms remains limited. Suppressed hippocampal neurogenesis in adult brains has been regarded, at least partly, contributive to depression, whereas physical exercise that restores neuro-genesis accordingly exerts the anti-depressive action. Several recent publications have suggested the potential role of adiponectin, a protein hormone secreted by peripheral mature adipocytes, in mediating physical exercise-triggered enhancement of hippocampal neurogenesis and alleviation of depression. Here, we brielfy review these novel ifndings and discuss the possibility of counter-acting depression by modulating adiponectin signaling in the hippocampus with interventions including physical exercise and administration of pharmacological agents.

    Fluoxetine, a selective serotonin reuptake inhibitor (SSRI), has effects beyond its antidepressant properties, altering, e.g., mechanisms involved in blood pressure and vasomotor tone control. Although many studies have addressed the acute impact of fluoxetine on the cardiovascular system, there is a paucity of information on the chronic vascular effects of this SSRI. We tested the hypothesis that chronic fluoxetine treatment enhances the vascular reactivity to vasodilator stimuli by increasing nitric oxide (NO) signaling and activation of potassium (K+) channels. Wistar rats were divided into two groups: (I) vehicle (water for 21 days) or (II) chronic fluoxetine (10 mg/kg/day in the drinking water for 21 days). Fluoxetine treatment increased endothelium-dependent and independent vasorelaxation (analyzed by mesenteric resistance arteries reactivity) as well as constitutive NO synthase (NOS) activity, phosphorylation of eNOS at Serine1177 and NO production, determined by western blot and fluorescence. On the other hand, fluoxetine treatment did not alter vascular expression of neuronal and inducible NOS or guanylyl cyclase (GC). Arteries from fluoxetine-treated rats exhibited increased relaxation to pinacidil. Increased acetylcholine vasorelaxation was abolished by a calcium-activated K+ channel (KCa) blocker, but not by an inhibitor of KATP channels. On the other hand, vascular responses to Bay 41-2272 and 8-bromo-cGMP were similar between the groups. In conclusion, chronic fluoxetine treatment increases endothelium-dependent and independent relaxation of mesenteric resistance arteries by mechanisms that involve increased eNOS activity, NO generation, and KCa channels activation. These effects may contribute to the cardiovascular effects associated with chronic fluoxetine treatment.

    Unlike classic serotonergic antidepressant drugs, ketamine, an NMDA receptor antagonist, exhibits a rapid and persistent antidepressant (AD) activity, at sub-anaesthetic doses in treatment-resistant depressed patients and in preclinical studies in rodents. The mechanisms mediating this activity are unclear. Here, we assessed the role of the brain serotonergic system in the AD-like activity of an acute sub-anaesthetic ketamine dose. We compared ketamine and fluoxetine responses in several behavioral tests currently used to predict anxiolytic/antidepressant-like potential in rodents. We also measured their effects on extracellular serotonin levels [5-HT]ext in the medial prefrontal cortex (mPFCx) and brainstem dorsal raphe nucleus (DRN), a serotonergic nucleus involved in emotional behavior, and on 5-HT cell firing in the DRN in highly anxious BALB/cJ mice. Ketamine (10 mg/kg i.p.) had no anxiolytic-like effect, but displayed a long lasting AD-like activity, i.e., 24 h post-administration, compared to fluoxetine (18 mg/kg i.p.). Ketamine (144%) and fluoxetine (171%) increased mPFCx [5-HT]ext compared to vehicle. Ketamine-induced AD-like effect was abolished by a tryptophan hydroxylase inhibitor, para-chlorophenylalanine (PCPA) pointing out the role of the 5-HT system in its behavioral activity. Interestingly, increase in cortical [5-HT]ext following intra-mPFCx ketamine bilateral injection (0.25 μg/side) was correlated with its AD-like activity as measured on swimming duration in the FST in the same mice. Furthermore, pre-treatment with a selective AMPA receptor antagonist (intra-DRN NBQX) blunted the effects of intra-mPFCx ketamine on both the swimming duration in the FST and mPFCx [5-HT]ext suggesting that the AD-like activity of ketamine required activation of DRN AMPA receptors and recruited the prefrontal cortex/brainstem DRN neural circuit in BALB/c mice. These results confirm a key role of cortical 5-HT release in ketamine's AD-like activity following the

    The first drug repurposed for the treatment of depression was the tuberculostatic iproniazid. At present, drugs belonging to new classes of antidepressants still have antimicrobial effects. Dysbiosis of gut microbiota was implicated in the development or exacerbation of mental disorders, such as major depressive disorder (MDD). Based on the current interest in the gut-brain axis, the focus of this narrative review is to compile the available studies regarding the influences of gut microbiota in behavior and depression and to show the antimicrobial effect of antidepressant drugs. A discussion regarding the possible contribution of the antimicrobial effect of antidepressant drugs to its effectiveness/resistance is included. The search included relevant articles from PubMed, SciELO, LILACS, PsycINFO, and ISI Web of Knowledge. MDD is associated with changes in gut permeability and microbiota composition. In this respect, antidepressant drugs present antimicrobial effects that could also be related to the effectiveness of these drugs for MDD treatment. Conversely, some antimicrobials present antidepressant effects. Both antidepressants and antimicrobials present neuroprotective/antidepressant and antimicrobial effects. Further studies are needed to evaluate the participation of antimicrobial mechanisms of antidepressants in MDD treatment as well as to determine the contribution of this effect to antidepressant resistance.

    The purpose of the present study was to evaluate the effectiveness of nitrofuranes applied for the treatment of chronic tonsillitis. A total of 92 subjects divided into three cohorts were involved in this study. Cohort 1 included 43 patients presenting with decompensated chronic tonsillitis and having pathogens in palatine tonsil lacunae. Cohort 2 was comprised of 13 patients with compensated chronic tonsillitis having pathogenic microflora of the same localization, while Cohort 3 was composed of 36 patients resembling those of cohort 1 in terms of clinical presentation, pathogen composition, and microbial spectrum. While the patients of cohort 1 and cohort 2 were treated by rinsing their tonsil lacunae with a furasol solution as a single-drug therapeutic procedure, those comprising Cohort 3 underwent treatment with furacilinum for the same purpose. The results of the study give evidence of the important advantages of furasol therapy over other modalities for the conservative treatment of chronic tonsillitis.

    Omalizumab is a recombinant humanized monoclonal antibody that inhibits immunoglobulin E. It has been approved for the treatment of severe asthma and chronic spontaneous urticaria refractory to other treatments. Its use in the management of chronic inducible urticaria (a type triggered by certain stimuli) is still considered off-label, although this use has been discussed in some consensus papers. This review brings together case reports and case series describing the use of omalizumab to treat chronic inducible urticaria. We analyze the most important aspects of the cases and the outcomes reported. The results seem to position omalizumab as a potentially effective, safe treatment alternative in some cases of chronic inducible urticaria. Copyright © 2016 AEDV.

Methods: Seventy-eight patients with major depressive disorder were stratified into two subgroups according to the presence of subthreshold bipolarity, identified using the Korean version of the Mood Disorder Questionnaire (K-MDQ, which classifies patients as positive for a screening of bipolarity based on the cutoff for the total K-MDQ score (ie, 7 points. They received AD monotherapy such as escitalopram, sertraline, paroxetine, or tianeptine for 6 months. The Beck Depression Inventory (BDI, Hamilton Depression Rating Scale (HAMD, Hamilton Anxiety Scale, and Beck Scale for Suicide Ideation were applied at baseline, 1 week, 3 weeks, 2 months, 3 months, and 6 months. Results: The mean HAMD, BDI, and Beck Scale for Suicide Ideation scores were higher in the bipolarity group than in the nonbipolarity group at 3 weeks. The mean BDI score was also higher in the bipolarity group than in the nonbipolarity group at 6 months. Evaluation of the ratio of improvement for each scale revealed different patterns of percentage changes between the two groups over the 6-month follow-up period. Furthermore, the response and remission rates (as assessed using BDI and HAMD scores were higher in the nonbipolarity group than in the bipolarity group, with the exception of HAMD scores at the 3-week follow-up time point. Conclusion: The findings of this study showed that depressed patients with bipolarity had a worse response to AD monotherapy than did those without bipolarity. Keywords: subthreshold bipolarity

    Factors contributing to treatment-emergent suicidal ideation (TESI) using antidepressants have been in the focus of recent research strategies. We investigated previously established clinical predictors of TESI and combined these with several polymorphisms of candidate genes in patients with major depressive disorder. Common polymorphisms involved in the tryptophan hydroxylase 1 (TPH1) and 2 (TPH2), serotonin transporter, monoamine oxidase A (MAOA) and brain-derived neurotrophic factor (BDNF) were investigated in a naturalistic inpatient study of the German research network on depression. We compared patients showing TESI with non-TESI suicidal patients and with non-suicidal patients using univariate tests to detect relevant factors, which were further tested in logistic regression and CART (Classification and Regression Trees) analyses. Of the 269 patients, TESI occurred in 22 patients (17 female), 117 patients were defined as non-TESI suicidal patients, and 130 patients were classified as non-suicidal. When comparing cases with both control groups we found the TPH2 rs1386494 (C/T) polymorphism to be moderately associated with TESI (Univariate tests: TESI vs. non-suicidality: p=0.005; adjusted: p=0.09; TESI vs. non-TESI suicidal patients: p=0.0024; adjusted: p=0.086). This polymorphism remained the only significant genetic factor in addition to clinical predictors in logistic regression and CART analyses. CART analyses suggested interactions with several clinical predictors. Haplotype analyses further supported a contribution of this polymorphism in TESI. The TPH2 rs1386494 (C/T) polymorphism might contribute to the genetic background of TESI. This polymorphism has been previously associated with committed suicide and major depressive disorder. The small number of cases warrants replication in larger patient samples. Lack of a placebo control group hampers definite conclusions on an association with antidepressive treatment.

    Meagan Osborn

    Full Text Available Depression is a chronic and debilitating condition with a significant degree of relapse and treatment resistance that could stem, at least in part, from disturbances of neuroplasticity. This has led to an increased focus on treatment strategies that target brain derived neurotrophic factor (BDNF, synaptic plasticity and adult neurogenesis. In the current study we aimed to assess whether erythropoietin (EPO would have antidepressant-like effects given its already established pro-trophic actions. In particular, we assessed whether EPO would diminish the deleterious effects of a social stressor in mice. Indeed, EPO induced anxiolytic and antidepressant-like responses in a forced swim test, open field, elevated-plus maze, and a novelty test, and appeared to blunt some of the negative behavioural effects of a social stressor. Furthermore, EPO promoted adult hippocampal neurogenesis, an important feature of effective antidepressants. Finally, a separate study using the mTOR inhibitor rapamycin revealed that antagonizing this pathway prevented the impact of EPO upon forced swim performance. These data are consistent with previous findings showing that the mTOR pathway and its neurogenic and synaptogenic effects might mediate the behavioral consequences of antidepressant agents. Our findings further highlight EPO as a possible adjunct treatment for affective disorders, as well as other stressor associated disorders of impaired neuroplasticity.

    Tricyclic antidepressants (TCAs) are an important analgesic treatment for neuropathic pain, though the neural substrates mediating these effects are poorly understood. We have used an integrative approach combining behavioural pharmacology with functional magnetic resonance imaging (fMRI) to investigate the effects of chronic treatment with the TCA desipramine, on touch-evoked pain (mechanical allodynia) and brain regional activity in the selective spinal nerve ligation (SNL) model of neuropathic pain. SNL and sham-operated rats received once daily i.p. administration of 10 mg/kg DMI, or saline, for 14 days. Withdrawal responses to the application of a normally non-noxious (10 g) stimulus were recorded in SNL and sham-operated rats over this period. On the final day of the study, SNL and sham-operated rats received a final challenge dose of DMI (10 mg/kg i.p.) during fMRI scanning. Chronic administration of desipramine (DMI) significantly attenuated mechancial allodynia in SNL rats. DMI challenge in chronic DMI-treated neuropathic rats produced significantly greater activation of the deep mesencephalic nucleus, primary somatosensory cortex, insular cortex, medial globus pallidus, inferior colliculus, perirhinal cortex and cerebellum compared to sham-operated rats and saline controls. By contrast, the spatial pattern of brain regional activation by chronic DMI treatment in sham controls encompassed a number of other areas including those associated with learning and memory processes. These novel findings identify key brain regions implicated in the analgesic and mood altering effects associated with chronic treatment with DMI.

    Full Text Available Although pregnancy was once thought to protect against psychiatric disorders, gravid and non gravid women have similar risks for major depression, at 10% to 15%. Both depression and antidepressant treatment during pregnancy have been associated with risks. Few medications have been proved unequivocally safe during pregnancy. Although certain antidepressants have not been linked with an increased risk of birth defects or impaired development including bupropion, citalopram, escitalopram and venlafaxine, the latest studies aren't necessarily reassuring. As researchers continue to learn more about antidepressants, the risks and benefits of taking the drugs during pregnancy must be weighed carefully on a case-by-case basis. This review discusses about the use of new generation of antidepressants in pregnancy

    Chronic urticaria often poses a therapeutic challenge. The human immune response to helminths has a high degree of similarity to an allergic response in terms of skin manifestations, eosinophilia, and IgE elevation. Unfortunately, it is often complicated to diagnose such infections. We sought to assess the effect of empirical anthelmintic treatment among returning travellers diagnosed with chronic urticaria, without clear proof of helminthic infection. This is a retrospective case series of 19 returning travellers with chronic urticaria. All patients were treated with anthelmintic treatment given based on clinical suspicion only. A randomly selected control group of 20 patients with chronic urticaria, with no history of travel, was also enrolled. A positive clinical response was reported in 68.4% (13 patients) of the travellers' group within 3 months after treatment with anthelmintic therapy compared with 10% (2 patients) of chronic urticaria patients in the control group. No adverse effects from treatment were recorded. In patients with chronic urticaria, travel history to developing countries must be obtained. Empiric anthelmintic therapy might be beneficial, even in the absence of findings suggestive of helminthic infection. © 2016 S. Karger AG, Basel.

    The purpose of this article is to present the characteristics of the Acceptance and Commitment Therapy (ACT) for the treatment of chronic pain. The historical context of the development of cognitive and behavioural therapy (CBT) for chronic pain will be described and the theoretical aspects of ACT will be introduced. The components of an acceptance and mindfulness based treatment will also be presented by exploring various processes of the psychological flexibility model. Finally, the article will summarize the scientific evidence supporting ACT based on experimental, correlational and clinical studies in the field of chronic pain. The theoretical aspects underlying ACT, as well as its clinical components in the specific domain of chronic pain were described based on major books in this area, such as McCracken (2005) and Dahl et al. (2005). A descriptive literature review was undertaken to explore the data on the efficacy of ACT for the treatment of chronic pain. Psycinfo and Medline, as well as the Association for Contextual Science website were analyzed for relevant articles. The key search terms were: "Acceptance and Commitment Therapy" or "ACT" or "acceptance" or "mindfulness" or "defusion" and "chronic pain" or "pain." The reference lists of the articles retrieved were also analyzed. The articles that were not in English or French were excluded as well as those that were not specific to ACT and chronic pain. Results show that ACT is a relevant and empirically supported approach that may be used as a complement to CBT strategies in the treatment of chronic pain. There is growing evidence stemming from experimental and correlational studies that support the majority of the ACT processes. Clinical studies undertaken in the field of chronic pain from different backgrounds support the efficacy of ACT for the management of this condition. ACT is a promising and evidence-based approach for the treatment of chronic pain. More research is needed to further validate its

    Full Text Available Migraine is a disabling neurologic condition with a spontaneous clinical evolution into a chronic form. Migraine progression from an episodic into a chronic form is realized through a period of time involving several months or years, during which an increase attack frequency occurs. .According to the International Classification of Headache Disorders (ICHD-3 chronic migraine is a type of primary headache occurring on 15 or more days per month for more than 3 months, in which more than 8 days per month headache meet criteria for migraine with or without aura or respond to specific migraine treatment. The prevalence of chronic migraine is estimated between 1- 3% of general population. Persons with chronic migraine are more likely to suffer from severe disability; chronic migraine has an important socio-economic impact. Diagnostic approach in chronic migraine includes exclusion of a secondary headache disorder and confirmation of a primary episodic headache. When a patient is found to overuse pain medication, diagnosis of both chronic migraine and MOH should be considered. Treating episodic migraine early and managing attack frequency using preventive medication and behavioural interventions will be benefic in reducing the risk of chronicisation. Lifestyle changes are important for avoiding triggers for migraine attacks; treatment of comorbidities is equally important because these conditions exacerbate patient’s tendency to have headaches. The initial relief step for drug abusers always relies in drug withdrawal. For migraine attacks treatment begins with non-pharmacologic interventions (staying in a quiet, dark room, pressure on painful areas, applying cold compresses , simple OTC analgetics (NSAIDs, paracetamol, aspirin, acetaminophen. If these are not effective, triptans are the drugs of choice. Preventive treatment is always recommended in patients with chronic migraine because the high frequency of headache attacks.

    Chronic treatment of pain with opiate drugs can lead to analgesic tolerance and drug dependence. Although all opiate drugs can promote tolerance and dependence in practice, the severity of those unwanted side effects differs depending on the drug used. Although each opiate drug has its own unique set of pharmacological profiles, methadone is the only clinically used opioid drug that produces substantial receptor endocytosis at analgesic doses. Here, we examined whether moderate doses of methadone carry any benefits over chronic use of equianalgesic morphine, the prototypical opioid. Our data show that chronic administration of methadone produces significantly less analgesic tolerance than morphine. Furthermore, we found significantly reduced precipitated withdrawal symptoms after chronic methadone treatment than after chronic morphine treatment. Finally, using a novel animal model with a degrading μ-opioid receptor we showed that, although endocytosis seems to protect against tolerance development, endocytosis followed by receptor degradation produces a rapid onset of analgesic tolerance to methadone. Together, these data indicated that opioid drugs that promote receptor endocytosis and recycling, such as methadone, may be a better choice for chronic pain treatment than morphine and its derivatives that do not.

    Beyond the current hypothesis of depression, several new biological substrates have been proposed for this disorder. The present study investigated whether the anti-inflammatory drugs celecoxib and piroxicam have antidepressant activity in animal models of depression. After acute administration, we observed antidepressant-like effects of celecoxib (10 mg/kg) and piroxicam (10 mg/kg) in the modified forced swim test in rats. Piroxicam increased serotonin and norepinephrine levels in the hippocampus. Prolonged (21-day) treatment with celecoxib (10 mg/kg) and piroxicam (10 mg/kg) rescued sucrose preference in a chronic mild stress model of depression. Additionally, the chronic mild stress-induced reduction of hippocampal glutathione was prevented by treatment with celecoxib and piroxicam. Superoxide dismutase in the hippocampus was increased after chronic mild stress compared with the non-stressed saline group. The non-stressed celecoxib and piroxicam groups and stressed piroxicam group exhibited an increase in hippocampal superoxide dismutase activity compared with the stressed saline group. Lipid hydroperoxide was increased in the stressed group treated with vehicle and non-stressed group treated with imipramine but not in the stressed groups treated with celecoxib and piroxicam. These results suggest that the antidepressant-like effects of anti-inflammatory drugs might be attributable to enhanced antioxidant defenses and attenuated oxidative stress in the hippocampus.

    The efficacy of tamsulosin in the treatment of chronic non-bacterial prostatitis was evaluated in a randomized clinical observation of 105 male outpatients conducted for 90 days. Patients were randomly divided into five groups (n = 21 per group) according to prostatitis type IIIA or IIIB and therapy regimens (tamsulosin, levofloxacin, or tamsulosin plus levofloxacin combination therapy). National Institutes of Health Chronic Prostatitis Symptom Index scores, expressed prostatic massage test and urodynamic urethral pressure and urethral closure pressure tests were performed to evaluate clinical efficacy of the treatments. Scores for pain, urinary symptoms and quality of life were significantly improved by days 45 and 90 after all treatments in both prostatitis categories. Improvements in symptom scores in the combined treatment group were significantly superior to those in the single treatment groups. Tamsulosin and levofloxacin are both effective in the treatment of, and may have an additive effect in, the treatment of non-bacterial prostatitis.

    Chronic Achilles tendinosis is a relatively common but difficult orthopedic condition to treat. In this study, autologous platelet rich plasma (PRP), a concentrated bioactive blood component rich in cytokines and growth factors, was evaluated to determine its potential long-term efficacy in treating chronic cases of Achilles tendinosis resistant to traditional nonoperative management. Thirty patients with chronic Achilles tendinosis who did not respond to a minimum of 6 months of traditional nonoperative treatment modalities were treated with a single ultrasound guided injection of PRP. AOFAS scoring was completed for all patients pretreatment and at 0, 1, 2, 3, 6, 12, and 24 months post-treatment. MRI and/or ultrasound studies were completed for all patients pre-treatment and at 6 months post-treatment. Prior to the PRP treatment all of the patients in this study were considering surgical Achilles repair for their severe symptoms. The average AOFAS score increased from 34 (range, 20 to 60) to 92 (range, 87 to 100) by 3 months after PRP treatment and remained elevated at 88 (range, 76 to 100) at 24 months post-treatment. Pretreatment imaging abnormalities present in the Achilles tendon on MRI and ultrasound studies resolved in 27 of 29 patients at 6 months post-treatment. Clinical success was achieved in 28 of 30 patients. Platelet-rich plasma was used effectively to treat chronic recalcitrant cases of Achilles tendinosis.

    Chronic systemic inflammation, a non traditional risk factor of cardiovascular diseases, is associated with increasing mortality in chronic kidney disease, especially peritoneal dialysis patients. Periodontitis is a potential treatable source of systemic inflammation in peritoneal dialysis patients. Clinical periodontal status was evaluated in 32 stable chronic peritoneal dialysis patients by plaque index and periodontal disease index. Hematologic, blood chemical, nutritional, and dialysis-related data as well as highly sensitive C-reactive protein were analyzed before and after periodontal treatment. At baseline, high sensitive C-reactive protein positively correlated with the clinical periodontal status (plaque index; r = 0.57, P chronic systemic inflammation in peritoneal dialysis patients. Treatment of periodontal diseases can improve systemic inflammation, nutritional status and erythropoietin responsiveness in peritoneal dialysis patients.

    Chronic wounds have become an increasing medical and economic problem of aging societies because they are difficult to manage. Skin grafting is an important treatment method for chronic wounds, which are refractory to conservative therapy. The technique involving epidermal cell suspensions was invented to enable the possibility of treating larger wounds with only a small piece of donor skin. Both uncultured and cultured autologous epidermal cell suspensions can be prepared and survive permanently on the wound bed. A systematic search was conducted of EMBASE, Cochrane Library, PubMed and web of science by using Boolean search terms, from the establishment of the database until May 31, 2014. The bibliographies of all retrieved articles in English were searched. The search terms were: (epithelial cell suspension OR keratinocyte suspension) and chronic and wound. From the included, 6 studies are descriptive interventions and discussed the use of autologous keratinocyte suspension to treat 61 patients' chronic wound. The various methods of preparation of epidermal cell suspension are described. The advantages and shortcomings of different carriers for epidermal cell suspensions are also summarised. Both uncultured and cultured autologous epidermal cell suspensions have been used to treat chronic wounds. Although the limitations of these studies include the small number of patient populations with chronic wounds and many important problems that remain to be solved, autologous epidermal cell suspension is a promising treatment for chronic wounds.

  20. Telbivudine: A new treatment for chronic hepatitis B

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Three hundred and fifty million people worldwide are estimated to be chronically infected with hepatitis B virus. 15%-40% of these subjects will develop cirrhosis,liver failure or hepatocellular carcinoma during their life. The treatment of chronic hepatitis B has improved dramatically over the last decade merits to the advent of nucleoside/nucleotide analogues and the use of pegylated interferons. Approved drugs for chronic hepatitis B treatment include: standard interferonalpha 2b, pegylated interferon-alpha 2a, lamivudine,adefovir dipivoxil, and entecavir. Unfortunately, these agents are not effective in all patients and are associated with distinct side effects. Interferons have numerous side effects and nucleoside or nucleotide analogues,which are well tolerated, need to be used for prolonged periods, even indefinitely. However, prolonged treatment with nucleoside or nucleotide analogues is associated with a high rate of resistance. Telbivudine is a novel,orally administered nucleoside analogue for use in the treatment of chronic hepatitis B. In contrast to other nucleoside analogues, Telbivudine has not been associated with inhibition of mammalian DNA polymerase with mitochondrial toxicity. Telbivudine has demonstrated potent activity against hepatitis B with a significantly higher rate of response and superior viral suppression compared with lamivudine, the standard treatment.Telbivudine has been generally well tolerated, with a low adverse effect profile, and at its effective dose, no doselimiting toxicity has been observed. Telbivudine is one of the most potent antiviral agents for chronic hepatitis B virus and was approved by the FDA in late 2006.

    2013-01-01

    The present study was designed to investigate the antidepressant potential of N-n-butyl-3-ethoxyquinoxalin-2-carboxamide (6p), a novel 5-HT3 receptor antagonist in rodent behavioral models of depression. The compound 6p was examined in various behavioral models like forced swim test (FST), tail suspension test (TST), mechanistic models [5-hydroxytryptophan (5-HTP)-induced head twitch and reserpine-induced hypothermia (RIH)], and in chronic surgery model-olfactory bulbectomy in rats. Compound 6p (1, 2, and 4 mg/kg, i.p.) exhibited antidepressant-like effect in FST and TST after acute treatment without having an effect on baseline locomotor activity. Moreover, 6p (2 mg/kg, i.p.), potentiated the 5-HTP-induced head twitch responses in mice and inhibited the RIH in rats. Chronic treatment (14 days) with 6p (1 and 2 mg/kg, p.o.) and paroxetine (10 mg/kg, p.o.) in rats significantly reversed the behavioral anomalies induced by bilateral olfactory bulbectomy using open field exploration. The preliminary studies reveal that compound 6p exhibits antidepressant-like effect in behavioral rodent models of depression.

  2. Spadin, a sortilin-derived peptide, targeting rodent TREK-1 channels: a new concept in the antidepressant drug design.

    Directory of Open Access Journals (Sweden)

    Jean Mazella

    Full Text Available Current antidepressant treatments are inadequate for many individuals, and when they are effective, they require several weeks of administration before a therapeutic effect can be observed. Improving the treatment of depression is challenging. Recently, the two-pore domain potassium channel TREK-1 has been identified as a new target in depression, and its antagonists might become effective antidepressants. In mice, deletion of the TREK-1 gene results in a depression-resistant phenotype that mimics antidepressant treatments. Here, we validate in mice the antidepressant effects of spadin, a secreted peptide derived from the propeptide generated by the maturation of the neurotensin receptor 3 (NTSR3/Sortilin and acting through TREK-1 inhibition. NTSR3/Sortilin interacted with the TREK-1 channel, as shown by immunoprecipitation of TREK-1 and NTSR3/Sortilin from COS-7 cells and cortical neurons co-expressing both proteins. TREK-1 and NTSR3/Sortilin were colocalized in mouse cortical neurons. Spadin bound specifically to TREK-1 with an affinity of 10 nM. Electrophysiological studies showed that spadin efficiently blocked the TREK-1 activity in COS-7 cells, cultured hippocampal pyramidal neurons, and CA3 hippocampal neurons in brain slices. Spadin also induced in vivo an increase of the 5-HT neuron firing rate in the Dorsal Raphe Nucleus. In five behavioral tests predicting an antidepressant response, spadin-treated mice showed a resistance to depression as found in TREK-1 deficient mice. More importantly, an intravenous 4-d treatment with spadin not only induced a strong antidepressant effect but also enhanced hippocampal phosphorylation of CREB protein and neurogenesis, considered to be key markers of antidepressant action after chronic treatment with selective serotonin reuptake inhibitors. This work also shows the development of a reliable method for dosing the propeptide in serum of mice by using AlphaScreen technology. These findings point out

  4. Outcome measures of antidepressive therapy.

    Rosenberg, R

    2000-01-01

    A variety of outcome measures assessing antidepressive therapy are available. However, in randomized clinical trials, the Hamilton Rating Scale for Depression (HAM-D) is often the primary outcome measure. Results from factor analysis and Rasch item analysis indicate that the HAM-D is heterogeneous and that the sum of items scores may not be an adequate measure of the severity of depression. A Melancholia Scale of 11 items has been suggested as a more valid measure of the core symptoms of affective syndrome. Other global outcome measures, focusing on health-related quality of life issues and on social functioning as well as macro-economic analyses are also used in depression. Applying stringent and well-documented outcome measures in randomized clinical trials of antidepressants may give the clinician a better indication of the most appropriate drug for treatment of the individual patient.

The most prevalent chronic pain condition is chronic low back pain (CLBP). CLBP may be nociceptive or neuropathic, or may incorporate both components. The presence of a neuropathic component is associated with more intense pain of longer duration, and a higher prevalence of co-morbidities. However, many physicians' knowledge of chronic pain mechanisms is currently limited and there are no universally accepted treatment guidelines, so the condition is not particularly well managed. Diagnosis should begin with a focused medical history and physical examination, to exclude serious spinal pathology that may require evaluation by an appropriate specialist. Most patients have non-specific CLBP, which cannot be attributed to a particular cause. It is important to try and establish whether a neuropathic component is present, by combining the findings of physical and neurological examinations with the patient's history. This may prove difficult, however, even when using screening instruments. Multimodal management: The multifactorial nature of CLBP indicates that the most logical treatment approach is multimodal: i.e. integrated multidisciplinary therapy with co-ordinated somatic and psychotherapeutic elements. As both nociceptive and neuropathic components may be present, combining analgesic agents with different mechanisms of action is a rational treatment modality. Individually tailored combination therapy can improve analgesia whilst reducing the doses of constituent agents, thereby lessening the incidence of side effects. This paper outlines the development of CLBP and the underlying mechanisms involved, as well as providing information on diagnosis and the use of a wide range of pharmaceutical agents in managing the condition (including NSAIDs, COX-2 inhibitors, tricyclic antidepressants, opioids and

    This study evaluated the antidepressant-like effect of insulin compared to sertraline and a combination of insulin and sertraline in streptozotocin (STZ)-induced type 2 diabetes mellitus (T2DM) rats submitted to the forced swim test (FST). Male Wistar rats were daily treated for 21 days with insulin (1 or 2 IU/kg, i.p.), with the selective serotonin reuptake inhibitor (SSRI), sertraline (10 mg/kg, i.p.), or with a combination of insulin (1 or 2 IU/kg, i.p.) and sertraline (10 mg/kg, i.p.) and submitted to the FST. We also evaluated the water and food intake, urine volume and weight gain of the rats. Rats treated with STZ showed impaired glucose tolerance. Chronic treatment with sertraline showed an antidepressant-like effect in non-diabetic and diabetic rats. Furthermore, sertraline promoted lower weight gain in diabetic rats. Insulin reduced the immobility behaviour in T2DM rats with impaired glucose tolerance. In conclusion, our results showed that insulin has an antidepressant-like effect comparable to that of sertraline. Sertraline is effective as an antidepressant and reduces weight gain, which reinforces its superiority over other SSRIs in the treatment of major depression disorder in patients with T2DM.

    The conservative management of chronic calcaneal paratenonitis is time-consuming and often unsatisfactory. A new, safe and simple technique is described. The crural fascia on both sides of the tendon is incised and left open, adhesions around the tendon are trimmed away, the strongly hypertrophied portions of the paratenon are removed and mobilisation is begun immediately after operation. Between 1961 and 1978 201 such operations were performed on 182 patients 62 of whom were top-ranking Finnish athletes. Only five patients were not athletes. The results, including early return to full activity, were excellent in 169, good in 25 and poor in seven cases. After operation one of the patients gained an Olympic gold medal; others have attained international prominence.

    Depression and anxiety are the most debilitating mood disorders with poor therapeutic recovery rates. In the last decades, 5-HT3 receptor antagonists have been identified as potential agents for mood disorders. The current investigation focuses on evaluating the, antidepressant and anti-anxiety like effects of a novel 5-HT3 antagonist, 4i (N-(3-chloro-2-methylphenyl) quinoxalin-2-carboxamide). Preliminary, in vitro 5-HT3 receptor binding affinity was performed in isolated longitudinal muscle-myenteric plexus from the guinea pig ileum. Consequently, neurobehavioral effects of 4i in acute and chronic rodent models were evaluated. In addition, involvement of serotonergic system in the postulated effects of the compound was analyzed by in vivo assay. in vitro, 4i demonstrated high 5-HT3 receptor antagonistic activity (pA2, 7.6). in vivo acute study, 4i exhibited decreased duration of immobility in forced swim and tail suspension tests, and increased exploratory parameters as number and duration of nose-poking in hole board test and latency and time spent in aversive brightly illuminated light chamber in light-dark model. Moreover, in chronic model of depression, i.e., olfactory bulbectomy with behavioral deficits, 4i reversed depressive anhedonia in sucrose preference test and anxious hyperactive behavior in open field test in rats. Furthermore, synergistic effect of 4i with fluoxetine (a selective serotonin reuptake inhibitor) and inhibitory effect of 1-(m-chlorophenyl)-biguanide (a 5-HT3 receptor agonist) revealed serotonergic modulation by 4i mediated 5-HT3 receptor antagonism, which was further confirmed by potentiation of 5-hydroxytryptophan (a serotonin synthesis precursor) induced head twitch response. These findings suggest the potential antidepressant and anti-anxiety like effects of 4i, which may be related to the modulation of serotonergic system. Copyright © 2014 Elsevier B.V.

    Chronic stress is the major cause of clinical depression. The behavioral signs of depression, including anhedonia, learning and memory deficits, and sleep disruption, result from the damaging effects of stress hormones on specific neural pathways. The Chinese tree shrew (Tupaia belangeri chinensis) is an aggressive non-human primate with a hierarchical social structure that has become a well-established model of the behavioral, endocrine, and neurobiological changes associated with stress-induced depression. The tricyclic antidepressant clomipramine treats many of the core symptoms of depression in humans. To further test the validity of the tree shrew model of depression, we examined the effects of clomipramine on depression-like behaviors and physiological stress responses induced by social defeat in subordinate tree shrews. Social defeat led to weight loss, anhedonia (as measured by sucrose preference), unstable fluctuations in locomotor activity, sustained urinary cortisol elevation, irregular cortisol rhythms, and deficient hippocampal long-term potentiation (LTP). Clomipramine ameliorated anhedonia and irregular locomotor activity, and partially rescued the irregular cortisol rhythm. In contrast, weight loss increased, cortisol levels were even higher, and in vitro LTP was still impaired in the clomipramine treatment group. These results demonstrate the unique advantage of the tree shrew social defeat model of depression.

    Background Although pharmacological and psychological interventions are both effective for major depression, in primary and secondary care settings antidepressant drugs remain the mainstay of treatment. Amongst antidepressants many different agents are available. Duloxetine hydrochloride is a dual reuptake inhibitor of serotonin and norepinephrine and has been licensed by the Food and Drug Administration in the US for major depressive disorder (MDD), generalised anxiety disorder, diabetic peripheral neuropathic pain, fibromyalgia and chronic musculoskeletal pain. Objectives To assess the evidence for the efficacy, acceptability and tolerability of duloxetine in comparison with all other antidepressant agents in the acute-phase treatment of major depression. Search methods MEDLINE (1966 to 2012), EMBASE (1974 to 2012), the Cochrane Collaboration Depression, Anxiety and Neurosis Controlled Trials Register and the Cochrane Central Register of Controlled Trials up to March 2012. No language restriction was applied. Reference lists of relevant papers and previous systematic reviews were hand-searched. Pharmaceutical company marketing duloxetine and experts in this field were contacted for supplemental data. Selection criteria Randomised controlled trials allocating patients with major depression to duloxetine versus any other antidepressive agent. Data collection and analysis Two review authors independently extracted data and a double-entry procedure was employed. Information extracted included study characteristics, participant characteristics, intervention details and outcome measures in terms of efficacy, acceptability and tolerability. Main results A total of 16 randomised controlled trials (overall 5735 participants) were included in this systematic review. Of these, three trials were unpublished. We found 11 studies (overall 3304 participants) comparing duloxetine with one selective serotonin reuptake inhibitor (SSRI) (six studies versus paroxetine, three studies

    Individuals with chronic widespread pain, including those with fibromyalgia, pose a particular challenge to treatment, given the modest effectiveness of pharmacological agents for this condition. The growing consensus indicates that the best approach to treatment involves the combination of pharmacological and non-pharmacological interventions. Several non-pharmacological interventions, particularly exercise and cognitive-behavioural therapy (CBT), have garnered good evidence of effectiveness as stand-alone, adjunctive treatments for patients with chronic pain. In this article, evidenced-based, non-pharmacological management techniques for chronic widespread pain are described by using two broad categories, exercise and CBT. The evidence for decreasing pain, improving functioning and changing secondary symptoms is highlighted. Lastly, the methods by which exercise and CBT can be combined for a multi-component approach, which is consistent with the current evidence-based guidelines of several American and European medical societies, are addressed.

  15. Antidepressants stimulate hippocampal neurogenesis by inhibiting p21 expression in the subgranular zone of the hipppocampus.

    Directory of Open Access Journals (Sweden)

    Robert N Pechnick

    Full Text Available The relationships among hippocampal neurogenesis, depression and the mechanism of action of antidepressant drugs have generated a considerable amount of controversy. The cyclin-dependent kinase (Cdk inhibitor p21(Cip1 (p21 plays a crucial role in restraining cellular proliferation and maintaining cellular quiescence. Using in vivo and in vitro approaches the present study shows that p21 is expressed in the subgranular zone of the dentate gyrus of the hippocampus in early neuronal progenitors and in immature neurons, but not in mature neurons or astroglia. In vitro, proliferation is higher in neuronal progenitor cells derived from p21-/- mice compared to cells derived from wild-type mice. Proliferation is increased in neuronal progenitor cells after suppression of p21 using lentivirus expressing short hairpin RNA against p21. In vivo, chronic treatment with the non-selective antidepressant imipramine as well as the norepinephrine-selective reuptake inhibitor desipramine or the serotonin-selective reuptake inhibitor fluoxetine all decrease p21 expression, and this was associated with increased neurogenesis. Chronic antidepressant treatment did not affect the expression of other Cdk inhibitors. Untreated p21-/- mice exhibit a higher degree of baseline neurogenesis and decreased immobility in the forced swim test. Although chronic imipramine treatment increased neurogenesis and reduced immobility in the forced swim test in wild-type mice, it reduced neurogenesis and increased immobility in p21-/- mice. These results demonstrate the unique role of p21 in the control of neurogenesis, and support the hypothesis that different classes of reuptake inhibitor-type antidepressant drugs all stimulate hippocampal neurogenesis by inhibiting p21 expression.

    The therapeutic effectiveness of nutritional support in the treatment of severe chronic hepatitis and posthepatitic cirrhosis was evaluated. 143 patients with severe chronic hepatitis and 83 with posthepatitic cirrhosis were evaluated with SGA for assessing the nutritional status before the treatment. Patients with severe chronic hepatitis were divided into three groups: group A subject to enteral nutrition (EN) and parenteral nutrition (PN), group B subject to comprehensive treatment (CT)+PN; group C subject to CT+EN. The patients with posthepatitic cirrhosis were divided into two groups: group D receiving CT and group E receiving CT+PN+EN. The function of liver and kidney and nutritional status were monitored to assess the therapy in 6 weeks. The results showed before treatment, over 90 % patients had moderate to severe malnutrition. After nutritional support, the liver function (ALT, T-bil) and nutritional status (TP, TC) in group A was improved significantly as compared with that in groups B and C (Pcirrhosis had malnutrition to varying degrees. The nutritional support treatment could obviously improve the nutritional status of these patients, and was helpful to ameliorate the liver function of the patients with severe chronic hepatitis. Among the methods of nutritional support treatment, PN combined with EN had the best effectiveness.

  17. Chronic proctalgia and chronic pelvic pain syndromes: New etiologic insights and treatment options

    This systematic review addresses the pathophysiology, diagnostic evaluation, and treatment of several chronic pain syndromes affecting the pelvic organs: chronic proctalgia, coccygodynia, pudendal neuralgia, and chronic pelvic pain. Chronic or recurrent pain in the anal canal, rectum, or other pelvic organs occurs in 7% to 24% of the population and is associated with impaired quality of life and high health care costs. However, these pain syndromes are poorly understood, with little research evidence available to guide their diagnosis and treatment. This situation appears to be changing: A recently published large randomized, controlled trial by our group comparing biofeedback, electrogalvanic stimulation, and massage for the treatment of chronic proctalgia has shown success rates of 85% for biofeedback when patients are selected based on physical examination evidence of tenderness in response to traction on the levator ani muscle-a physical sign suggestive of striated muscle tension. Excessive tension (spasm) in the striated muscles of the pelvic floor appears to be common to most of the pelvic pain syndromes. This suggests the possibility that similar approaches to diagnostic assessment and treatment may improve outcomes in other pelvic pain disorders.

    Full Text Available This is a report of four cases of possible suicidal ideation with the use of antidepressants in Indian population. The patients presented to emergency department of a tertiary care hospital with attempted suicide. All of them were prescribed at least one antidepressant. The association of increased suicidal attempts/ideation with antidepressant drugs themselves has been reported in the West, but data in the Indian population are lacking. Antidepressants are widely used not only for treatment of depression but also many other psychiatric illnesses; it is yet unclear whether suicidal ideation is because of these drugs or the progression of the disease. Hence, careful prescribing of these medicines is warranted.

    In the efficacy evaluation of antidepressant treatments, the total score of the Hamilton Depression Rating Scale (HAMD) is still regarded as the 'gold standard'. We previously had shown that the Inventory of Depressive Symptomatology (IDS) was more sensitive to detect depressive symptom changes than the HAMD17 (Helmreich et al. 2011). Furthermore, studies suggest that the unidimensional subscales of the HAMD, which capture the core depressive symptoms, outperform the full HAMD regarding the detection of antidepressant treatment effects. The aim of the present study was to compare several unidimensional subscales of the HAMD and the IDS regarding their sensitivity to changes in depression symptoms in a sample of patients with mild major, minor or subsyndromal depression (MIND). Biweekly IDS-C28 and HAMD17 data from 287 patients of a 10-week randomised, placebo-controlled trial comparing the effectiveness of sertraline and cognitive-behavioural group therapy in patients with MIND were converted to subscale scores and analysed during the antidepressant treatment course. We investigated sensitivity to depressive change for all scales from assessment-to-assessment, in relation to depression severity level and placebo-verum differences. The subscales performed similarly during the treatment course, with slight advantages for some subscales in detecting treatment effects depending on the treatment modality and on the items included. Most changes in depressive symptomatology were detected by the IDS short scale, but regarding the effect sizes, it performed worse than most subscales. Unidimensional subscales are a time- and cost-saving option in judging drug therapy outcomes, especially in antidepressant treatment efficacy studies. However, subscales do not cover all facets of depression (e.g. atypical symptoms, sleep disturbances), which might be important for comprehensively understanding the nature of the disease depression. Therefore, the cost-to-benefit ratio must be

    38 patients with severe chronic arteritis of the lower limbs were treated with streptokinase intermittently. All had been refused for surgical operation. One patient died, 4 others had early interruption of treatment. Eleven of the 38 patients had efficient thrombolysis confirmed by arteriography. The facts confirm the possibility of thrombolysis during chronic arterial disease. The fact that the aggravation was recent was favourable factor in prognosis. The eleven patients improved, had severe aggravation of symptomes for less than 2 months. Thus thrombolytic treatment has a place of choice in the treatment of severe arterial disease where surgery is impossible, or dangerous, owing to the uncertain state of the vascular bed below the lesion. Efficacious, it permits reconstructive surgery in cases where it had been at first refused. The use of intermittent treatment, apart from advantages of confort and cost, seems to increase the efficacy of treatment.

    Treatment's initiation in chronic inflammatory demyelinating polyradiculopathy (CIDP) remains a difficult medical decision. Only plasma exchanges, intravenous immunoglobulins (IVIg) and corticosteroids are proven effective treatments. Immunosuppressors are actually not first-line treatments in CIDP. Particular CIDP forms are associated with different response to treatments: pure motor CIDP should be treated by IVIg, and corticosteroids should only carefully be used in Lewis-Sumner syndrome. Otherwise, IVIg are first-line treatment in diabetic patients. Patients must be informed of side's effects and expected clinical effects. Early treatment was actually not proved to prevent axonal damages in CIDP patients, and waiting seems to be the best therapeutic option in poorly symptomatic patients. Recently, clinical guidelines were proposed to help clinician in this treatment choice, but there is no consensus about the best dose, duration or administration way to CIDP treatments. Further studies should be performed to clarify these points and to determine immunosuppressor agents place in treatment strategy.

    Pegylated interferon and ribavirin combination therapy is accepted as the standard antiviral treatment for chronic hepatitis C regardless of HCV genotype. This combination therapy achieves higher response rates than previous therapy, but, nevertheless, a large proportion of patients suffer from treatment failure or adverse events. Recent clinical studies of viral kinetics during antiviral treatment have led to the introduction of response-guided therapy, the concept of 'customized therapy depending on viral response', which focuses on modulation of the treatment period depending on the viral response to create a sustained viral response without unnecessary medication and costs. New upcoming direct-acting antivirals (DAAs) maximize response rate, and triple therapy including DAAs along with pegylated interferon and ribavirin combination therapy could soon be the standard therapy. In this article, we reviewed the factors affecting treatment, response guided treatment, retreatment after failure of standard treatment, management of adverse events during treatment, and new treatment options.

    Several multi-target drugs used in treating psychiatric disorders, such as antidepressants (e.g. agomelatine, trazodone, nefazodone, amitriptyline, mirtazapine, mianserin, fluoxetine) or most atypical antipsychotics, have 5-hydroxytryptamine 2C (5-HT2C) receptor-blocking property. Adaptive changes in 5-HT2C receptor-mediated functions are suggested to contribute to therapeutic effects of selective serotonin reuptake inhibitor (SSRI) antidepressants after weeks of treatment, at least in part. Beyond the mediation of anxiety and other functions, 5-HT2C receptors are involved in sleep regulation. Anxiety-related adaptive changes caused by antidepressants have been studied extensively, although sleep- and electroencephalography (EEG)-related functional studies are still lacking. The aim of this study was to investigate the effects of chronic SSRI treatment on 5-HT2C receptor antagonist-induced functions in different vigilance stages and on quantitative EEG (Q-EEG) spectra. Rats were treated with a single dose of the selective 5-HT2C receptor antagonist SB-242084 (1 mg/kg, i.p.) or vehicle at the beginning of passive phase following a 20-day-long SSRI (escitalopram; 10 mg/kg/day, osmotic minipump) or VEHICLE pretreatment. Fronto-parietal electroencephalogram, electromyogram and motility were recorded during the first 3 h of passive phase. We found that the chronic escitalopram pretreatment attenuated the SB-242084-caused suppression in rapid eye movement sleep (REMS). On the contrary, the 5-HT2C receptor antagonist-induced elevations in passive wake and theta (5-9 Hz) power density during active wake and REMS were not affected by the SSRI. In conclusion, attenuation in certain, but not all vigilance- and Q-EEG-related functions induced by the 5-HT2C receptor antagonist, suggests dissociation in 5-HT2C receptor adaptation.

    This study evaluates group treatment for women suffering from chronic pelvic pain. The concept of group treatment was based on psychosomatic and physio-therapeutical principles and on cognitive and operant behavioral therapy. Each group was composed of up to six women suffering from chronic pelvic pain, and two physiotherapists. Each group treatment session lasted 2.5 h per week for a period of 10 weeks. The women completed questionnaires and pain drawings four times during the treatment period from the beginning of the period till 15 months later. During 13 group treatment periods 53 women accomplished the treatment. Before the treatment the women had experienced pain for an average period of 5 years and 9 months (ranging from 6 months to 22 years). The women's descriptions of the changes derived from group treatment were analyzed according to the Grounded Theory Method. A methodical triangulation of quantitative and qualitative data as well as analyzes of the drawings were applied. One year after the end of the treatment, 39% of the women were pain-free. The average level of pain measured according to the Visual Analog Scale was reduced from 2.8 to 0.9 (p Theory Analysis a model of the development process was elaborated. The process begins with the development of self-knowledge, followed by the woman assuming self responsibility for her own life and performing self-activeness. During the process the woman increases her feeling of self-control and personal mastery of her emotions. The women's pain drawings improved, resulting in more detailed drawings, the color intensity abating, the extent of pains declining, and the outlines blurring. In conclusion this kind of group treatment brings the women relief from their pain thus reducing the use of the National Health Service by women suffering from chronic pelvic pain. The women also experience a positive psychological development. This method of treatment, in which a synergetic combination of physical and

    Mindfulness-based cognitive therapy (MBCT) showed efficacy for currently depressed patients. However, most of the available studies suffer from important methodological shortcomings, including the lack of adequate control groups. The present study aims to compare MBCT with a psycho-educational control group designed to be structurally equivalent to the MBCT program but excluding the main putative "active ingredient" of MBCT (i.e., mindfulness meditation practice) for the treatment of patients with major depression (MD) who did not achieve remission following at least 8 weeks of antidepressant treatment. Out of 106 screened subjects, 43 were randomized to receive MBCT or psycho-education and were prospectively followed for 26 weeks. MD severity was assessed with the Hamilton Rating Scale for Depression (HAM-D) and the Beck Depression Inventory-II (BDI-II). Measures of anxiety, mindfulness, and quality of life were also included. All assessments were performed at baseline, 4, 8, 17 and 26-weeks. Both HAM-D and BDI scores, as well as quality of life and mindfulness scores, showed higher improvements, which were particularly evident over the long-term period, in the MBCT group than in the psycho-education group. Although limited by a small sample size, the results of this study suggest the superiority of MBCT over psycho-education for non-remitted MD subjects.

    Recent clinical trials suggest that 3 single biological treatments have effects that persist. Based on research showing that the muscles involved in facial expressions can feed back to influence mood, a single trial diminishing glabella frown lines with botulinum toxin demonstrated a significant antidepressant effect for 16 weeks. Based primarily on research with animal models of depression suggesting that glutamate may be involved in depression, the N-methyl-D-aspartate antagonist ketamine has been tested in several trials. A single dose decreased depression for up to a week. The reported effects of the use of mushrooms containing psilocybin by a number of cultures around the world has stimulated several trials showing beneficial effects of a single dose of psilocybin for over a year in healthy people, and for up to 3 months in patients with anxiety disorders who have advanced cancer. This article discusses these studies, their rationale, their possible mechanisms of action, the future clinical research required to establish these therapies and the basic research required to optimize single treatments that have lasting effects.

    Chronic pruritus is a distressing symptom that is often refractory to treatment. Patients frequently fail topical therapies and oral over-the-counter antihistamines, prompting the clinician to consider alternative therapies such as neuroactive agents. Herein, the use of gabapentin and pregabalin, 2 medications well known for treating neuropathic pain and epilepsy that are occasionally used for relieving chronic pruritus is explored. The findings from original sources published to date to evaluate the use of gabapentin and pregabalin as antipruritic agents are explored. They are found to be promising alternative treatments for the relief of several forms of chronic pruritus, particularly uremic pruritus and neuropathic or neurogenic itch, in patients who fail conservative therapies.

    Full Text Available Chronic migraine is a condition with significant prevalence all around the world and high socioeconomic impact, and its handling has been challenging neurologists. Developments for understanding its mechanisms and associated conditions, as well as that of new therapies, have been quick and important, a fact which has motivated the Latin American and Brazilian Headache Societies to prepare the present consensus. The treatment of chronic migraine should always be preceded by a careful diagnosis review; the detection of possible worsening factors and associated conditions; the stratification of seriousness/impossibility to treat; and monitoring establishment, with a pain diary. The present consensus deals with pharmacological and nonpharmacological forms of treatment to be used in chronic migraine.

  13. Antidepressants reduce extinction-induced withdrawal and biting behaviors: a model for depressive-like behavior.

    The withholding of expected rewards results in extinction of behavior and, hypothetically, to depression-like symptoms. In a test of this hypothesis, we examined the effects of extinction of food-reinforced lever-pressing on collateral behaviors that might be indices of depression. Operant extinction is known to be aversive to the organism and results in avoidance behavior. We hypothesized that avoidance of, or withdrawal from, the former source of reward may serve as a marker for "despair." Adult male Wistar rats (n=6-7 animals per group) were exposed to a Skinner box attached to a second compartment of the same size, providing opportunity for the animals to leave the operant chamber and to enter the "withdrawal" compartment. The animals spent a portion of the time during the extinction trials in this second chamber. To assess the predictive validity of this behavior as a potential marker of "despair," we tested the effects of chronic administration of two common antidepressant drugs on this measure. The tricyclic antidepressant imipramine (20 mg/kg) as well as the selective serotonin reuptake inhibitor citalopram (20 mg/kg) reduced the number of entries and time spent in the withdrawal compartment. We propose that entries into and time spent in the withdrawal compartment may operationalize "avoidance," a core symptom of major depression. Rearing as well as biting behaviors during the extinction trials were also attenuated by the antidepressant treatment. These results lend support to the hypothesis that extinction of positively reinforced operants evokes behaviors that reflect elements of "despair/depression" because these behaviors are modulated by antidepressant treatment. The avoidance of the operant chamber as a consequence of extinction, together with rearing and biting behaviors, may serve as useful measures for the testing of antidepressant treatments.

    Objective To study serious harms associated with selective serotonin and serotonin-norepinephrine reuptake inhibitors. Design Systematic review and meta-analysis. Main outcome measures Mortality and suicidality. Secondary outcomes were aggressive behaviour and akathisia. Data sources Clinical study reports for duloxetine, fluoxetine, paroxetine, sertraline, and venlafaxine obtained from the European and UK drug regulators, and summary trial reports for duloxetine and fluoxetine from Eli Lilly’s website. Eligibility criteria for study selection Double blind placebo controlled trials that contained any patient narratives or individual patient listings of harms. Data extraction and analysis Two researchers extracted data independently; the outcomes were meta-analysed by Peto’s exact method (fixed effect model). Results We included 70 trials (64 381 pages of clinical study reports) with 18 526 patients. These trials had limitations in the study design and discrepancies in reporting, which may have led to serious under-reporting of harms. For example, some outcomes appeared only in individual patient listings in appendices, which we had for only 32 trials, and we did not have case report forms for any of the trials. Differences in mortality (all deaths were in adults, odds ratio 1.28, 95% confidence interval 0.40 to 4.06), suicidality (1.21, 0.84 to 1.74), and akathisia (2.04, 0.93 to 4.48) were not significant, whereas patients taking antidepressants displayed more aggressive behaviour (1.93, 1.26 to 2.95). For adults, the odds ratios were 0.81 (0.51 to 1.28) for suicidality, 1.09 (0.55 to 2.14) for aggression, and 2.00 (0.79 to 5.04) for akathisia. The corresponding values for children and adolescents were 2.39 (1.31 to 4.33), 2.79 (1.62 to 4.81), and 2.15 (0.48 to 9.65). In the summary trial reports on Eli Lilly’s website, almost all deaths were noted, but all suicidal ideation events were missing, and the information on the remaining outcomes was

    The therapeutic effectiveness of nutritional support in the treatment of severe chronic hepatitis and posthepatitic cirrhosis was evaluated. 143 patients with severe chronic hepatitis and 83 with posthepatitic cirrhosis were evaluated with SGA for assessing the nutritional status before the treatment. Patients with severe chronic hepatitis were divided into three groups: group A subject to enteral nutrition (EN) and parenteral nutrition (PN), group B subject to comprehensive treatment (CT) +PN; group C subject to CT+ EN. The patients with posthepatitic cirrhosis were divided into two groups: group D receiving CT and group E receiving CT+PN+EN. The function of liver and kidney and nutritional status were monitored to assess the therapy in 6 weeks. The results showed before treatment, over 90 % patients had moderate to severe malnutrition. After nutritional support, the liver function (ALT, T-biil) and nutritional status (TP, TC) in group A was improved significantly as compared with that in groups B and C (P<0.05). Compared with group D,the values of TP and Alb were increased significantly in group E (P<0.05), but the levels of ALT, AST and T-bil had no obvious change. It was suggested that most patients with severe chronic hepatitis or posthepatitic cirrhosis had malnutrition to varying degrees. The nutritional support treatment could obviously improve the nutritional status of these patients, and was helpful to ameliorate the liver function of the patients with severe chronic hepatitis. Among the methods of nutritional support treatment, PN combined with EN had the best effectiveness.

    Depression has been associated with a low-grade chronic inflammatory state, suggesting a potential therapeutic role for anti-inflammatory agents. Fisetin is a naturally occurring flavonoid in strawberries that has anti-inflammatory activities, but whether fisetin has antidepressant effects is unknown. In this study, we exposed mice to spatial restraint for 2 weeks with or without treatment with fisetin. Immobility time in the forced swimming and tail suspension test after this restraint increased in the untreated group, but this increase did not occur in the fisetin group. We administered fisetin to Abelson helper integration site-1 (Ahi1) knockout mice, which have depressive phenotypes. We found that fisetin attenuated the depressive phenotype of these Ahi1 knockout mice. We further investigated the potential mechanism of fisetin's antidepressant effects. Because TrkB is a critical signaling pathway in the mechanisms of depression, we examined whether phosphorylated TrkB was involved in the antidepressant effects of fisetin. We found that fisetin increased phosphorylated TrkB level without altering total TrkB; this increase was attenuated by K252a, a specific TrkB inhibitor. Taken together, our results demonstrated that fisetin may have therapeutic potential for treating depression and that this antidepressant effect may be mediated by the activation of the TrkB signaling pathway.

    Full Text Available Thomas King, John McKenna, Anton B Alexandroff Department of Dermatology, University Hospitals of Leicester, Leicester Royal Infirmary, Leicester, UK Abstract: Chronic hand eczema is a common and often debilitating condition. Alitretinoin, a 9-cis-retinoic acid and pan-retinoic acid agonist, is a new and effective systemic treatment for chronic hand eczema, which provides another treatment option. A “clear” or “almost clear” response can be achieved in up to half of patients within a 24-week course of treatment. Even higher rates of remission can be obtained with a longer duration of treatment. Alitretinoin has a favorable overall profile of adverse effects; however, female patients who are at risk of becoming pregnant should follow a strict pregnancy-prevention program due to the teratogenic effects of this drug.

    Depression is one of the most frequent and severe mental disorder. Since the discovery of antidepressant (AD) properties of the imipramine and then after of other tricyclic compounds, several classes of psychotropic drugs have shown be effective in treating major depressive disorder (MDD). However, there is a wide range of variability in response to ADs that might lead to non response or partial response or in increased rate of relapse or recurrence. The mechanisms of response to AD therapy are poorly understood, and few biomarkers are available than can predict response to pharmacotherapy. Here, we will first review markers that can be used to predict response to pharmacotherapy, such as markers of drug metabolism or blood-brain barrier (BBB) function, the activity of specific brain areas or neurotransmitter systems, hormonal dysregulations or plasticity, and related molecular targets. We will describe both clinical and preclinical studies and describe factors that might affect the expression of these markers, including environmental or genetic factors and comorbidities. This information will permit us to suggest practical recommendations and innovative treatment strategies to improve therapeutic outcomes. PMID:24319431

    Conclusions: There is wide price variation of different brands of the same generic antidepressant drug in Indian market. Cost of a drug plays an important role in treatment of depression as it follows a long course and adherence to the treatment is related with drug cost. To decrease the wide cost variation among different brands of antidepressant drugs; it is high time to generate physician awareness about impact of cost effectiveness of drug regimen and for regulation of drug prices by the concerned agencies.

    Patients' attributions of effects of treatment are important, as these can affect long-term outcome. Most studies so far focused on the influence of attributions to medication for anxiety and depression disorders. We investigated the effects of patients' attributions made after acute treatment on the long-term outcome of antidepressant medication (ADM) and psychological treatment (behavioural activation, BA). Data are based on a randomized trial testing the effectiveness of BA vs. ADM for major depression (MDD) in Iran. Patients with MDD (N = 100) were randomized to BA (N = 50) or ADM (N = 50). Patients' attributions were assessed at post-test (after completion of the treatments). Scores on an attribution questionnaire were factor analysed, and factor scores were retained as predictors of depressive symptoms at 1-year follow-up. Regression analysis was used to test whether attributions predicted depressive symptoms at 1-yr follow-up, controlling for symptom level, condition, and their interaction at post-test. Belief in coping efficacy was the only attribution factor significantly predicting 1-year HRSD scores, controlling for condition, post-test HRSD and their interaction. It also mediated the condition differences at follow-up. Credit to self was the single attribution factor that predicted BDI follow-up scores, controlling for condition, posttest BDI, and their interaction. It partially mediated the condition differences on the BDI at follow-up. Attribution to increased coping capacities and giving credit to self appear essential. In the long-term (at 1 year follow-up), the difference in outcome between BA and ADM (with BA being superior to ADM) is at least partially mediated by attributions. Copyright © 2015 Elsevier Ltd.
