    Full Text Available BACKGROUND: With the availability of new preventive and curative interventions, global malaria control has been strengthened significantly in recent years. Drugs effective in reducing malaria gametocytaemia might contribute to local elimination and possible long-term eradication. We here report on the effects of methylene blue (MB-based malaria combination therapy on gametocytaemia during a randomised-controlled trial in Burkina Faso. METHODS: An open-label randomised controlled phase II study in 180 children aged 6-10 years with uncomplicated falciparum malaria was conducted in Nouna, north-western Burkina Faso. Children were randomised to MB-artesunate (AS, MB-amodiaquine (AQ, and AS-AQ (local standard of care. Overall follow-up was for 28 days, follow-up for gametocytaemia was for 14 days. FINDINGS: The treatment groups were similar in baseline characteristics and there was only one loss to follow-up. Compared to AS-AQ, both MB-containing regimens were associated with significantly reduced gametocyte carrier rates during follow-up days 3, 7, and 14. This effect was seen both in patients with and without P. falciparum gametocytaemia at baseline. INTERPRETATION: MB reveals pronounced gametocytocidal activity which appears to act against both existing and developing P. falciparum gametocytes. MB-based combination therapy thus has the potential to reduce transmission of P. falciparum malaria in endemic regions, which has important implications for future elimination and eradication strategies.

    Molybdenum blues (MB) based nanocomposites of polypyrrole (PPY), polyN-vinylcarbazole (PNVC) and their binary combination (PPY-PNVC) were prepared by in situ polymerization (without using external oxidant) of PY and NVC and also by using ammonium perdisulfate oxidant (PDS). Formation and incorporation of PPY and PNVC in the respective MB based composite was confirmed by FTIR spectral analyses. Scanning electron microscopic (SEM) analyses revealed the formation of PPY-MB, PNVC-MB and PPY-MB-PNVC composite particles with average diameter in the nanometer range. Thermogravimetric analyses (TGA) showed the following thermal stability trend: MB > PPY-MB > PNVC-MB > PPY-MB-PNVC > PPY {>=} PNVC. Differential thermal analysis (DTA) for the PPY-MB-PNVC composite revealed exothermic oxidative degradation process characteristics of PPY and PNVC backbones. DC conductivity values (S/cm) for PPY-MB, PNVC-MB and PPY-MB-PNVC were 1.5 x 10{sup -5} and 7 x 10{sup -2} (a value 10{sup 12}-fold improved compared to that of unmodified PNVC-10{sup -12} to 10{sup -16}), respectively.

    In the prevention of coronary heart disease the aim to achieve the target cholesterol and triglyceride levels and the maximal risk reduction leads to the combination of lipid lowering agents. The importance of the combination is supported by the fact that in monotherapy use of the high dose of the drugs, the lipid lowering effect is modest and the side effects are more frequent. The combined therapy is expected to be used more frequently despite the fact, that the improperly applied combination could have serious unfavourable effects. The authors review the advantages and drawbacks of the fibrate-statin combination, which could be used in the most frequent lipid abnormality, the high cholesterol and high triglyceride level, when the combination of micronized fenofibrate and fluvastatin is recommended. Beside the co-administration of other lipid lowering drugs (nicotine acid and resins), it is discussed the combination of statins and fibrates with a new, cholesterol absorption inhibitor, ezetimibe, a well tolerated drug with advantageous safety profile. Considering further metabolic risks the combination of lipid lowering drugs with glitazones, hormone replacement therapy, homocysteine reducing agents is as well highlighted.

    Full Text Available The availability of oral iron chelators and new non-invasive methods for early detection and treatment of iron overload, have significantly improved the life expectancy and quality of life of patients with b thalassemia major. However, monotherapy is not effective in all patients for a variety of reasons. We analyzed the most relevant reports recently published on alternating or combined chelation therapies in thalassemia major with special attention to safety aspects and to their effects in terms of reduction of iron overload in different organs, improvement of complications, and survival. When adverse effects, such as gastrointestinal upset with deferasirox or infusional site reactions with deferoxamine are not tolerable and organ iron is in an acceptable range, alternating use of two chelators (drugs taken sequentially on different days, but not taken on the same day together may be a winning choice. The association deferiprone and deferoxamine should be the first choice in case of heart failure and when dangerously high levels of cardiac iron exist. Further research regarding the safety and efficacy of the most appealing combination treatment, deferiprone and deferasirox, is needed before recommendations for routine clinical practice can be made.

    Antiresorptive agents for treating postmenopausal osteoporosis include selective estrogen receptor modulator (SERM), bisphosphonates and denoumab. Teriparatide is the only Food and Drug Administration-approved anabolic agent. Synergistic effects of combining teriparatide with an antiresorptive agent have been proposed and studied. This article reviews the trial designs and the outcomes of combination therapies. Results of the combination therapy for teriparatide and bisphosphonates were mixed; while small increases of bone density were observed in the combination therapy of teriparatide and estrogen/SERM and that of teriparatide and denosumab. Those clinical studies were limited by small sample sizes and lack of fracture outcomes.

    2003-01-01

    Hepatocellular carcinoma (HCC) is one of the most commonmalignancies in the world, responsible for an estimated one million deaths annually. It has a poor prognosis due to its rapid infiltrating growth and complicating liver cirrhosis.Surgical resection, liver transplantation and cryosurgery are considered the best curative options, achieving a high rate of complete response, especially in patients with small HCC and good residual liver function. In nonsurgery, regional interventional therapies have led to a major breakthrough in the management of unresectable HCC, which include transarterial chemoembolization (TACE), percutaneous ethanol injection (PEI), radiofrequency ablation (RFA), microwave coagulation therapy (MCT), laser-induced thermotherapy (LITT), etc. As a result of the technical development of locoregional approaches for HCC during the recent decades,the range of combined interventional therapies has been continuously extended. Most combined multimodal interventional therapies reveal their enormous advantages as compared with any single therapeutic regimen alone,and play more important roles in treating unresectable HCC.

    Full Text Available Diabetic macular edema is a main reason for visual loss in diabetic patients. Until recent years, macular laser photocoagulation was the only available therapy. The awareness that inflammation is an important factor in the pathogenetic process of DME gave reason for intravitreal treatment with corticosteroids. The introduction of anti-VEGF drugs brought a revolutionary change in the treatment of DME. This paper will review the important clinical trials with an emphasis on combination therapies.

    2014-04-01

    Pneumonia's burden is still important worldwide not only because of its high incidence and mortality, but also for the elevated costs related to it. Despite the concerted efforts to reduce the incidence of sepsis-related complications, they continue to represent a major human and economic burden. The cornerstone of sepsis management is early appropriate empiric broad spectrum antibiotics, resuscitation, and source control. The association between inappropriate use of antibiotics and increased mortality is the rationale for the use of empiric antibiotic combination therapy in critically ill patients. The aim of this manuscript was to discuss recent literature regarding the management of severe pneumonia, both community-acquired and hospital-acquired/ventilator-associated, in critically ill patients. Use of combination therapy is warranted in severe infections with shock; considerations should be made on the importance of optimal antibiotic administration and adverse reactions, thus providing guidance for a rational use of antibiotics.

    The article discusses the possible etiological factors in the development of chronic bacterial prostatitis. The authors presented a comparative long-term analysis of morbidity from non-viral sexually transmitted infections (STIs) in Russia. Against the background of general decline in STIs incidence, a significant percentage of them is made up by urogenital trichomoniasis. The findings substantiated the advantages of combination therapy (ornidazole and ofloxacin) for bacterial urinary tract infections.

    Full Text Available Objective. The study was designed to determine the efficacy of combined Amodiaquine and Ciprofloxacin in plasmodiasis therapy. Method. The in vivo antiplasmodial effect of different dosage levels of Amodiaquine, Ciprofloxacin, and their combinations against Plasmodium berghei berghei was evaluated using Swiss albino mice. Results. Amodiaquine (a known antiplasmodial agent had a fairly significant antiplasmodial effect reducing the parasites for every 100 red blood cells (RBC from 66 to 16 (75.75% at the tolerable dosage level of 7.5 mg/kg body weight while Ciprofloxacin (an antibiotic known to have antimalarial effect showed an insignificant antiplasmodial effect reducing the parasites for every 100 RBC from 65 to 64 (1.53% at the tolerable dosage level of 10.7 mg/kg body weight. Conversely, the combination therapy of Amodiaquine and Ciprofloxacin had a significant antiplasmodial effect at all the doses administered. The combination of 7.5 mg/kg of Amodiaquine and 12.8 mg/kg of Ciprofloxacin, however, showed the most significant antiplasmodial effect of the doses used reducing the number of parasites per 100 RBC from 60 to 10 (83.33%. Conclusions. Appropriate Amodiaquine and Ciprofloxacin combination will be effective for the treatment of malaria and better than either Amodiaquine or Ciprofloxacin singly at their recommended dosage levels.

    Combination with cabergoline may offer additional benefits to acromegalic patients on pegvisomant monotherapy. We evaluated the safety and efficacy profile of this combination and investigated the determinants of response. An observational, retrospective, cross-sectional study. Fourteen acromegalic patients (9 females), who were partially resistant to somatostatin analogs and on pegvisomant monotherapy. Cabergoline was added because of the presence of persistent mildly increased IGF-I. The mean follow-up time was 18.3 ± 10.4 months. The efficacy and safety profile was assessed. The influence of clinical and biochemical characteristics on treatment efficacy was studied. IGF-I levels returned to normal in 4 patients (28%) at the end of the study. In addition, some decline in IGF-I levels was observed in a further 5 patients. The % IGF-I decreased from 158 ± 64% to 124 ± 44% (p = 0.001). The average change in IGF-I was -18 ± 27% (range -67 to +24%). Lower baseline IGF-I (p = 0.007), female gender (p = 0.013), lower body weight (p = 0.031), and higher prolactin (PRL) levels (p = 0.007) were associated with a better response to combination therapy. There were no significant severe adverse events. Significant tumour shrinkage was observed in 1 patient. Combination therapy with pegvisomant and cabergoline could provide better control of IGF-I in some patients with acromegaly. Baseline IGF-I levels, female gender, body weight, and PRL levels affect the response to this combination therapy.

    The success of sorafenib in prolonging survival of patientswith hepatocellular carcinoma (HCC) makes therapeuticinhibition of angiogenesis a component of treatmentfor HCC. To enhance therapeutic efficacy, overcome drug resistance and reduce toxicity, combination ofantiangiogenic agents with chemotherapy,radiotherapyor other targeted agents were evaluated. Nevertheless,the use of antiangiogenic therapy remains suboptimalregarding dosage, schedule and duration of therapy.The issue is further complicated by combinationantiangiogenesis to other cytotoxic or biologic agents.There is no way to determine which patients are mostlikely respond to a given form of antiangiogenic therapy.Activation of alternative pathways associated with diseaseprogression in patients undergoing antiangiogenictherapy has also been recognized. There is increasingimportance in identifying, validating and standardizingpotential response biomarkers for antiangiogenesistherapy for HCC patients. In this review, biomarkers forantiangiogenesis therapy including systemic, circulating,tissue and imaging ones are summarized. The strengthand deficit of circulating and imaging biomarkerswere further demonstrated by a series of studies inHCC patients receiving radiotherapy with or withoutthalidomide.

  15. Combination therapy in hypertension: An update

    Full Text Available Abstract Meticulous control of blood pressure is required in patients with hypertension to produce the maximum reduction in clinical cardiovascular end points, especially in patients with comorbidities like diabetes mellitus where more aggressive blood pressure lowering might be beneficial. Recent clinical trials suggest that the approach of using monotherapy for the control of hypertension is not likely to be successful in most patients. Combination therapy may be theoretically favored by the fact that multiple factors contribute to hypertension, and achieving control of blood pressure with single agent acting through one particular mechanism may not be possible. Regimens can either be fixed dose combinations or drugs added sequentially one after other. Combining the drugs makes them available in a convenient dosing format, lower the dose of individual component, thus, reducing the side effects and improving compliance. Classes of antihypertensive agents which have been commonly used are angiotensin receptor blockers, thiazide diuretics, beta and alpha blockers, calcium antagonists and angiotensin-converting enzyme inhibitors. Thiazide diuretics and calcium channel blockers are effective, as well as combinations that include renin-angiotensin-aldosterone system blockers, in reducing BP. The majority of currently available fixed-dose combinations are diuretic-based. Combinations may be individualized according to the presence of comorbidities like diabetes mellitus, chronic renal failure, heart failure, thyroid disorders and for special population groups like elderly and pregnant females.

    Full Text Available When managing patients with locomotor pathology, serious attention is paid to symptomatic therapy aimed at eliminating the unpleasant manifestations of the disease. At the same time, rational analgesia is of the greatest importance. If acute pain should be arrested, parenteral or tableted formulations of fast-acting analgesics are used for days. Longer analgesic therapy especially for clinically relevant inflammation is based on the use of nonsteroidal anti-inflammatory drugs (NSAID having analgesic and anti-inflammatory effectiveness and good tolerance. The level of analgesia may be increased, by combining NSAID with tramadol and paracetamol. When clinical muscular spasm is implicated in the pathogenesis of chronic pain, it is expedient to prescribe myorelaxants that have an analgesic potential and are able to potentiate the analgesic effect of NSAID.

    Full Text Available Diabetic macular edema (DME is the main cause of visual impairment in diabetic patients. Macular edema within 1 disk diameter of the fovea is present in 9% of the diabetic population. The management of DME is complex and often multiple treatment approaches are needed. This review demonstrates the benefits of intravitreal triamcinolone, bevacizumab and ranibizumab as adjunctive therapy to macular laser treatment in DME. The published results indicate that intravitreal injections of these agents may have a beneficial effect on macular thickness and visual acuity, independent of the type of macular edema that is present. Therefore, pharmacotherapy could complement focal/grid laser photocoagulation in the management of DME. For this review, we performed a literature search and summarized recent findings regarding combined therapy for DME.

    MicroRNAs (miRNAs) and siRNAs have enormous potential as cancer therapeutics, but their effective delivery to most solid tumors has been difficult. Here, we show that a new lung-targeting nanoparticle is capable of delivering miRNA mimics and siRNAs to lung adenocarcinoma cells in vitro and to tumors in a genetically engineered mouse model of lung cancer based on activation of oncogenic Kirsten rat sarcoma viral oncogene homolog (Kras) and loss of p53 function. Therapeutic delivery of miR-34a, a p53-regulated tumor suppressor miRNA, restored miR-34a levels in lung tumors, specifically down-regulated miR-34a target genes, and slowed tumor growth. The delivery of siRNAs targeting Kras reduced Kras gene expression and MAPK signaling, increased apoptosis, and inhibited tumor growth. The combination of miR-34a and siRNA targeting Kras improved therapeutic responses over those observed with either small RNA alone, leading to tumor regression. Furthermore, nanoparticle-mediated small RNA delivery plus conventional, cisplatin-based chemotherapy prolonged survival in this model compared with chemotherapy alone. These findings demonstrate that RNA combination therapy is possible in an autochthonous model of lung cancer and provide preclinical support for the use of small RNA therapies in patients who have cancer.

    Cancer is a leading cause of death among modern people largely due to metastatic disease. The ideal cancer treatment should target both the primary tumor and the metastases with minimal toxicity towards normal tissue. This is best accomplished by priming the body's immune system to recognize the tumor antigens so that after the primary tumor is destroyed, distant metastases will also be eradicated. Photodynamic therapy (PDT) involves the IV administration of photosensitizers followed by illumination of the tumor with red light producing reactive oxygen species leading to vascular shutdown and tumor cell death. Anti-tumor immunity is stimulated after PDT due to the acute inflammatory response, generation of tumor-specific antigens, and induction of heat-shock proteins. Combination regimens using PDT and immunostimulating treatments are likely to even further enhance post-PDT immunity. These immunostimulants are likely to include products derived from pathogenic microorganisms that are effectively recognized by Toll-like receptors and lead to upregulation of transcription factors for cytokines and inflammatory mediators. The following cascade of events causes activation of macrophages, dendritic and natural killer cells. Exogenous cytokine administration can be another way to increase PDT-induced immunity as well as treatment with a low dose of cyclophosphamide that selectively reduces T-regulatory cells. Although so far these combination therapies have only been used in animal models, their use in clinical trials should receive careful consideration.

    To review the newest research about the effects of combination antiretroviral therapy (cART) on cancer risk. HIV+ persons are at increased risk of cancer. As this risk is higher for malignancies driven by viral and bacterial coinfections, classifying malignancies into infection-related and infection-unrelated has been an emerging trend. Cohorts have detected major reductions in the incidence of Kaposi sarcoma and non-Hodgkin lymphoma (NHL) following cART initiation among immunosuppressed HIV+ persons. However, recent randomized data indicate that cART reduces risk of Kaposi sarcoma and NHL also during early HIV infection before overt immunosuppression occurs. Long-term effects of cART exposure on cancer risk are not well defined; according to basic and epidemiological research, there might be specific associations of each cART class with distinct patterns of cancer risk. The relationship between cART exposure and cancer risk is complex and nuanced. It is an intriguing fact that, whether initiated during severe immunosuppression or not, cART reduces risk of Kaposi sarcoma and NHL. Further research should identify mediators of the benefit of immediate cART initiation in reducing cancer risk, understand the relationship between long-term cART exposure and cancer incidence and assess whether adjuvant anti-inflammatory therapies can reduce cancer risk during treated HIV infection.

    2008-05-01

    Invasive fungal infections have extremely high rates of morbidity and mortality, particularly in immunocompromised hosts. Combination antifungal therapy is conceptually attractive as a life-saving measure. However, in-vitro and in-vivo evidence is often conflicting and clinical trials in this area are limited. Most clinical studies show similar outcomes for combination antifungal therapy when compared to monotherapy, although secondary endpoints and sub-analyses often show advantages for the combinations in endpoints such as culture sterilisation. The logistics of large clinical trials of combination therapy are highly complex. Combination of antifungals with immune modulators is an exciting new research area. Until more data are available, clinicians should approach combination antifungal therapy with caution.

    The introduction of oral phosphodiesterase-5 inhibitors (PDE5ls) in the late 1990s and early 2000s revolutionized the field of sexual medicine and PDE5ls are currently first-line monotherapy for erectile dysfunction (ED). However, a significant proportion of patients with complex ED will be therapeutic non-responders to PDE5I monotherapy. Combination therapy has recently been adopted for more refractory cases of ED, but a critical evaluation of current combination therapies is lacking. A thorough PubMed and Cochrane Library search was conducted focusing on the effectiveness of combination therapies for ED in therapeutic non-responders to PDE5I therapy. Journal articles spanning the time period between January 1990 and December 2010 were reviewed. Criteria included all pertinent review articles, randomized controlled trials, cohort studies and retrospective analyses. References from retrieved articles were also manually scanned for additional relevant publications. Published combination therapies include PDE5I plus vacuum erectile device (VED), intraurethral medication, intracavernosal injection (ICI), androgen supplement, a-blocker or miscellaneous combinations. Based on this review, some of these combination treatments appeared to be quite effective in preliminary testing. Caution must be advised, however, as the majority of combination therapy articles in the last decade have numerous limitations including study biases and small subject size. Regardless of limitations, present combination therapy research provides a solid foundation for future studies in complex ED management.

Combination therapy using anti-angiogenic agents and radiation has shown promise; however, these combined therapies are reported to have many limitations in clinical trials. Here, we show that radiation transformed tumor endothelial cells (ECs) to fibroblasts, resulting in reduced vascular endothelial growth factor (VEGF) response and increased Snail1, Twist1, Type I collagen, and transforming growth factor (TGF)-β release. Irradiation of radioresistant Lewis lung carcinoma (LLC) tumors greater than 250 mm{sup 3} increased collagen levels, particularly in large tumor vessels. Furthermore, concomitant sunitinib therapy did not show a significant difference in tumor inhibition versus radiation alone. Thus, we evaluated multimodal therapy that combined pirfenidone, an inhibitor of TGF-induced collagen production, with radiation and sunitinib treatment. This trimodal therapy significantly reduced tumor growth, as compared to radiation alone. Immunohistochemical analysis revealed that radiation-induced collagen deposition and tumor microvessel density were significantly reduced with trimodal therapy, as compared to radiation alone. These data suggest that combined therapy using pirfenidone may modulate the radiation-altered tumor microenvironment, thereby enhancing the efficacy of radiation therapy and concurrent chemotherapy. - Highlights: • Radiation changes tumor endothelial cells to fibroblasts. • Radio-resistant tumors contain collagen deposits, especially in tumor vessels. • Pirfenidone enhances the efficacy of combined radiation and sunitinib therapy. • Pirfenidone reduces radiation-induced collagen deposits in tumors.

  11. Rationale for combination therapy as initial treatment for hypertension.

    Recent hypertension guidelines recommend initiating antihypertensive therapy with a combination of two or more agents in patients whose blood pressure exceeds their appropriate blood pressure goal by 20/10 mm Hg. This recommendation is based on the knowledge that the majority of patients with blood pressures of this magnitude will not achieve sufficient blood pressure reduction with monotherapy. Further, compared with high-dose monotherapy, combination therapy is often associated with fewer adverse effects and, for this reason, may improve patient adherence. Bringing patients to blood pressure goal quickly is likely to improve clinical outcomes. This article discusses the rationale for using combination antihypertensive therapy as initial therapy for high blood pressure in selected patients and reviews data from a study of 364 high-risk patients with Stage 2 hypertension in which a fixed-dose combination product (amlodipine besylate/benazepril HCl) proved more successful as initial therapy than high-dose monotherapy (amlodipine besylate) in reducing blood pressure.

    Full Text Available Widespread emergence of multidrug resistant (MDR bacterial pathogens is a problem of global dimension. MDR infections are difficult to treat and frequently associated with high mortality. More than one antibiotic is commonly used to treat such infections, but scientific evidence does not favor use of combination therapy in most cases. However, there are certain subgroups where combination therapy may be beneficial, e.g. sepsis due to carbapenem-resistant Enterobacteriaceae (CRE, bacteremic pneumococcal pneumonia, and patients with multiple organ failure. Well-designed prospective studies are needed to clearly define the role of combination therapy in these subgroups.

    Full Text Available Daclatasvir (DCV and asunaprevir (ASV are direct-acting antivirals (DAAs used in the treatment of chronic hepatitis C virus (HCV infection. Combined therapy with DCV and ASV shows high efficacy and safety even in patients with cirrhosis. We encountered a patient exhibiting severe hyperbilirubinemia during combined therapy, which is an unreported side effect of DCV and ASV. A 78-year-old woman with cirrhosis developed hyperbilirubinemia >10 mg/dl without transaminitis 3 weeks after starting combined therapy. We suspected DAAs-induced liver disorder and discontinued treatment, which resulted in the improvement of hyperbilirubinemia. Caution is required in the use of DAAs for patients with advanced cirrhosis.

    Full Text Available Abstract Background The current recommended therapy for diffuse coccidioidal pneumonia involves initial treatment with amphotericin B deoxycholate or high-dose fluconazole, followed by an azole after clinical improvement. Amphotericin B is more frequently used as initial therapy if the patient's deterioration is rapid. Case presentation A 31-year-old Korean male with coccidioidomycosis presented to the hospital with miliary infiltrates on chest X-ray (CXR and skin rash on the face and trunk. Initially, the patient did not respond to amphotericin B deoxycholate therapy. However, following caspofungin and fluconazole combination therapy, the patient showed favourable radiological, serological, and clinical response. Conclusion This appears to be the first case of diffuse coccidioidal pneumonia with skin involvement in an immunocompetent patient who was treated successfully with caspofungin and fluconazole. Combination therapy with caspofungin and fluconazole may, therefore, be an alternative treatment for diffuse coccidioidal pneumonia that does not respond to amphotericin B deoxycholate therapy.

    A combined deferasirox (DFX) and deferiprone (DFP) treatment protocol for relieving thalassemia patients' iron-overload was designed and the pharmacokinetic study was performed by LC-MS/MS. For this open-label, randomized trial, eight patients were recruited and randomly allocated to different treatment regimens: (A) monotherapy with single oral dose of DFX 30 mg/kg, (B) monotherapy with DFP 80 mg/kg/day, twice daily, (C) combined therapy with DFX and DFP (DFX 30 mg/kg for first dose, DFP 40 mg/kg 7 hours later, and DFP 40 mg/kg after another 7 h) and (D) concurrent therapy with DFX 30 mg/kg and DFP 80 mg/kg. Descriptive statistics evaluated pharmacokinetic parameters, AUC0-t, AUC0-inf, Cmax, Tmax, T1/2 and MRT. A positive pharmacokinetic drug interaction was observed in combined therapy. In case of DFX, combined therapy tallied about 2-fold larger than monotherapy in AUC, 1.5-fold larger in Cmax, 1 h longer in Tmax, but 1 h shorter in T1/2. Regarding DFP, most such parameters of combined therapy concurred with monotherapy. Conversely, negative drug interaction was observed in concurrent therapy. With DFX, concurrent therapy attained 1.2- to 2.2-fold lower than monotherapy in AUC0-t and Cmax, 0.6-h shorter in Tmax, and 3-fold longer in T1/2. With DFP, concurrent therapy proved approximately 2-fold larger than monotherapy in AUC and Cmax, 2.5-fold longer in T1/2, and 1.4-fold longer in MRT. Follow-up of subjects' clinical examinations and subjective symptoms showed no adverse events. Our findings showed the combined therapy had advantages, safe, convenient and painless for patients, over the existing concurrent therapy with deferoxamine (DFO) and DFX.

    The combined use of aspirin and oral anticoagulant therapy in patients with atrial fibrillation (AF) and stable coronary artery disease (CAD) has been questioned due to an increased risk of major bleeding with little to no benefit in preventing ischemic events. (1) To better understand patterns and indications for combined antiplatelet and anticoagulant therapy and identify patients who might reasonably be treated with oral anticoagulant (OAC) therapy alone. (2) To perform an updated literature review regarding the use of combined antiplatelet and OAC therapy in patients with AF and stable CAD. Retrospective review. Patients within the University of Cincinnati Health System with a diagnosis of non-valvular AF, excluding those with acute coronary syndrome or revascularization within the last 12 months. Numbers and indications for combined antiplatelet and anticoagulant therapy and sequence of events leading to the initiation of each. Of 948 patients receiving OAC, 430 (45 %) were receiving concomitant OAC and aspirin. Among patients receiving combined antiplatelet and anticoagulant therapy, 49 and 42 % of patients respectively, had CAD or DM. In a more detailed analysis including chart review of 219 patients receiving combined OAC and aspirin, 27 % had a diagnosis of CAD and 14 % had a diagnosis of DM prior to the development of AF. These patients were initially treated with aspirin. Warfarin was added when they subsequently developed AF but aspirin wasn't discontinued. A surprisingly large proportion of patients (22.8 %) had no obvious indication for dual therapy. Prior myocardial infarction, CAD, vascular disease and DM (among others) increase the likelihood of receiving combined antiplatelet and anticoagulant therapy among patients with AF. A literature review suggests this may lead to increased major bleeding with little benefit in decreasing either AF-related stroke or cardiovascular events.

    Carbapenem-resistant Gram-negative bacteria (CR-GNB) represent an increasing hazard in healthcare settings. A central question concerning the treatment of invasive infections caused by CR-GNB involves the use of combination therapy. Potential advantages of combination therapy include improved efficacy due to synergy, while the disadvantages include adverse events and increased antibiotic use with a potential drive towards resistance. Several observational studies have examined whether combination therapy offers an advantage over colistin/polymyxin monotherapy. We highlight the inherent limitations of these studies related to their observational design and sample size to show why they do not at present provide an answer to the question of combination versus monotherapy. This distinction is important to guide clinical practice until solid evidence has been obtained and to enable the recruitment of patients into randomized controlled trials. A few randomized controlled trials examining specific combinations have recently been completed or are ongoing. Currently, however, there is no evidence-based support for most combination therapies against CR-GNB, including colistin/carbapenem combination therapy.

    Full Text Available Background: Rheumatoid arthritis (RA is a chronic inflammatory condition. The condition can affected many tissues throught out the body, but the joints are usually most severely affected. The high incidence of RA, the conventional treatments and the experimental observation have shown by combination therapy, the disease symptoms of the patients reduce. To compare the efficacy and tolerability of single-agent Hydroxychloroquin (HCQ with combination therapies composed of (HCQ and Methotrexate (MTX and (HCQ, (MTX and Sulfasalazin (SSZ in active rheumatoid arthritis patients with additive arthritis. Methods: One hundred and twenty RA patients with active arthritis (male/female: 30/90 who were treated in rheumatology clinic between 2003 and 2005 were enrolled in this trial. Patients treated with (HCQ alone(200 mg/daywere include in group (I, patients treated with combination of (HCQ (200 mg/dayand (MTX (7.5mg/weekin group (II,and patents treated with combination of (HCQ (200mg/day,(MTX (7.5mg/weekand (SSZ(1 gr/dayin group (III, Forty patients (male/female:10/30 in group (I,(II and (IIIwere eligible for statistical analysis at the end of study. Changes in variable were compared by the T-test. Results: The combination of (MTX, (HCQand (SSZ and the combination of (MTX and (HCQ were more effective regarding the clinical and laboratory parameters than (HCQ alone (P<0.05. Moreover the combination of (MTX, (HCQ and (SSZ was more effective than the combination of (MTX and (HCQ (P<0.05. Combination therapies seem to be more effective and no more toxic than monotherapy in RA patients with additive arthritis. Conclusion: Combination therapy with methotrexate, hydroxychloroquin and sulfasalazin is more effective than hydroxychloroquin alone or a combination of methotrexate and hydroxychloroquin in RA. We suggest starting combination therapy for the patients with early RA, when the diagnosis has been established.

    Extensive basic science research has identified the potential therapeutic benefits of active compounds extracted from the Cannabis sativa L. plant (the cannabinoids). It is recognized that a significant proportion of patients suffering with the debilitating symptoms of pain and spasticity in multiple sclerosis or other conditions smoke cannabis despite the legal implications and stigma associated with this controlled substance. GW Pharmaceuticals have developed Sativex (GW- 1,000-02), a combined cannabinoid medicine that delivers and maintains therapeutic levels of two principal cannabinoids, delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), via an oromucosal pump spray, that aims to minimize psychotropic side effects. Sativex has proved to be well tolerated and successfully self-administered and self-titrated in both healthy volunteers and patient cohorts. Clinical assessment of this combined cannabinoid medicine has demonstrated efficacy in patients with intractable pain (chronic neuropathic pain, pain due to brachial plexus nerve injury, allodynic peripheral neuropathic pain and advanced cancer pain), rheumatoid arthritis and multiple sclerosis (bladder problems, spasticity and central pain), with no significant intoxication-like symptoms, tolerance or withdrawal syndrome.

    Full Text Available Abstract From an historical point of view, combination therapy was the basis for the care of important diseases like infection diseases or cancer. Today the "cocktail drug" of the Highly Active Anti Retroviral Therapy (HAART has reduced the death for HIV infection changing the outcome of such disease. Moreover, the combination of different strategies changed the course of transplants (both in haematology and surgical transplant. Different diseases with high social impact including cardiovascular, metabolic (obesity, hypercholesterolaemia and diabetes and autoimmune diseases, have better results with combinations of different drug classes of drugs. After recent successes in the immunotherapy field (Sepuleucel-T, ipilimumab and the new promising small molecule therapies, cancer should be the next challenge for combination strategies.

    Doxycycline is the standard systemic treatment for rosacea. Recently, there have been a few reports on β-adrenergic blockers such as nadolol, carvedilol and propranolol for suppressing flushing reactions in rosacea. To our knowledge, there are no comparative studies of propranolol and doxycycline, and combination therapy using both. The aim of this study was to investigate and compare the efficacy and safety of monotherapy of propranolol, doxycycline and combination therapy. A total of 78 patients who visited Pusan National University Hospital and were diagnosed with rosacea were included in this study. Among them, 28 patients were in the propranolol group, 22 the doxycycline group and 28 the combination group. We investigated the patient global assessment (PGA), investigator global assessment (IGA), assessment of rosacea clinical score (ARCS) and adverse effects. Improvement in PGA and IGA scores from baseline was noted in all groups, and the combination therapy was found to be the most effective during the entire period, but this was statistically insignificant. The reduction rate of ARCS during the treatment period was also highest in the combination group (57.4%), followed by the doxycycline group (52.2%) and the propranolol group (51.0%). Three patients in the combination group had mild and transient gastrointestinal disturbances but there was no significant difference from the other groups. We conclude that the combination therapy of doxycycline and propranolol is effective and safe treatment for rosacea and successful for reducing both flushing and papulation in particular.

    Cancer is characterized by the dysregulation of cell signaling pathways at several steps. The majority of current anticancer therapies involve the modulation of a single target. A tumor-targeting drug-delivery system consists of a tumor detection moiety and a cytotoxic material joined directly or through a suitable linker to form a conjugate. Photodynamic therapy has been used for more than 100 years to treat tumors. One of the present goals of photodynamic therapy research is to enhance the selective targeting of tumor cells in order to reduce the risk and extension of unwanted side-effects, caused by normal cell damage. Sonodynamic therapy is a promising new treatment for patients with cancer. It treats cancer with ultrasound and sonosensitive agents. Porphyrin compounds often serve as photosensitive and sonosensitive agents. The combination of these two methods makes cancer treatment more effective. The present review provides an overview of photodynamic therapy, sonodynamic therapy, sono-photodynamic therapy and the four sensitizers which are suitable candidates for combined sono-photodynamic therapy.

    Background and aim: We investigated the anti-tumor effect induced by the combination of the radiotherapeutic agent {sup 131}I-RC-160 and the prodrug 5-FC in human non-small cell lung cancer (NSCLC) A549 cells that were co-expressing the human somatostatin receptor 2 gene (hSSTR2) and E. coli cytosine deaminase gene (CD). Methods: We cloned both hSSTR2 and CD into a bicistronic mammalian expression plasmid and stably transfected it into A549 cells (pCIS-A549 cells). After antibiotic selection, SSTR expression in stable clones was determined by reverse transcription and polymerase chain reaction (RT-PCR), Western blot, flow cytometry and immunofluorescence analyses. To assess the in vivo targeting efficiency of the 'engineered' A549 cells, the cells were subcutaneously injected into nude mice and the biodistribution of {sup 99m}Tc-RC-160 was assessed at different time points. The tumor inhibitory effects of {sup 131}I-RC-160 and/or 5-FC were evaluated by measurement of tumor growth and immunohistochemical analysis. Results: Multiple analyses demonstrated the successful expression of hSSTR2 in A549 cells. In vivo radioimaging revealed specific targeting of RC-160 to the tumors derived from pCIS-A549 cells when compared to those from control A549 cells. The tumor inhibitory rate of pCIS-A549 tumors in the {sup 131}I-RC-160 plus 5-FC-treated group was significantly higher than that in the single agent-treated group, control group and control tumors. Conclusion: Co-expression of the hSSTR2 and CD genes in tumor cells can selectively sensitize these cells to the infra-additive effects of radioisotope-labeled RC-160 and 5-FC in vivo. This approach offers a potential therapeutic strategy for the treatment of lung cancer.

    Combining the latest targeted biologic agents with the most advanced radiation technologies has been an exciting development in the treatment of cancer patients. Stereotactic body radiation therapy (SBRT) is an ablative radiation approach that has become established for the treatment of a variety of malignancies, and it has been increasingly used in combination with biologic agents, including those targeting angiogenesis-specific pathways. Multiple reports have emerged describing unanticipated toxicities arising from the combination of SBRT and angiogenesis-targeting agents, particularly of late luminal gastrointestinal toxicities. In this review, we summarize the literature describing these toxicities, explore the biological mechanism of action of toxicity with the combined use of antiangiogenic therapies, and discuss areas of future research, so that this combination of treatment modalities can continue to be used in broader clinical contexts.

  12. The role of combination therapy in the treatment of hypertension.

    Science.gov (United States)

    Ruilope, L M; Coca, A

    1998-01-01

    Antihypertensive therapy is indicated for reducing the risk of cardiovascular morbidity and mortality that accompanies arterial hypertension. Usually, pharmacological treatment is started as monotherapy, which, if unsuccessful, is followed by sequential monotherapy, or by combination therapy. Recent data indicate that combination therapy is required in more than 50% of the hypertensive population when the goal is to reduce blood pressure to below 140/90 mm Hg. The choice and doses of drugs used in combination therapy should be such that their synergistic effect on blood pressure is maximized, the tolerability of the drugs is maintained and side-effects are minimized. The combination of a dihydropyridine calcium antagonist with a beta-blocker or an angiotensin-converting enzyme (ACE) inhibitor is one of the most commonly used combination therapies. Two randomized, double-blind, parallel-group studies compared the antihypertensive effects of the dihydropyridine, barnidipine, with the beta-blocker, atenolol (n = 247), and the ACE inhibitor, enalapril (n = 155). The efficacy and tolerability of barnidipine in combination with either atenolol or enalapril was also investigated. Monotherapy with barnidipine was as effective in reducing blood pressure as monotherapy with either atenolol or enalapril. Combining barnidipine with either atenolol or enalapril reduced blood pressure further, and significantly increased the percentage of patients attaining the required reduction in blood pressure. When patients whose blood pressure was not adequately controlled by enalapril monotherapy were switched to barnidipine monotherapy, the majority then achieved the desired reduction in blood pressure. These results indicate that if barnidipine monotherapy fails to lower blood pressure to the desired values, its combination with either a beta-blocker or an ACE inhibitor is effective and well tolerated.

    Full Text Available Introduction Rhabdomyolysis is a rare, but serious and potentially fatal adverse reaction of the statin application that may be developed in any time of therapy. It is characterized by massive destruction of muscles associated with the large increase of creatine kinase (CK leading to myoglobinuria and potential acute renal failure. Combined statin-fibrate therapy increases the risk of rhabdomyolysis, especially in elderly and diabetic patients. Case report An 81-year-old male was admitted to Coronary Care Unit of the Emergency Center, Clinical Center of Serbia (CCS with the clinical picture and electrocardiogram of the acute anterior wall myocardial infarction complicated with pulmonary edema. Laboratory tests on admission showed higher elevated values of serum creatinine 179 μmol/L and BUN 9.2 mmol/L (eGFR 32 mL/min/1.73m2, CK 309 U/L (on day 2: 3476 U/L and mixed hyperlipidemia (total cholesterol 10.3 mmol/L, HDL 2.26 mmol/L, TG 4.85 mmol/L. The patient was treated with thrombolysis medication therapy (Alteplase, anticoagulant and dual antiplatelet therapy, diuretics, organic nitrates, angiotensin-converting enzyme (ACE inhibitors, antibiotics, and proton pump inhibitors. During seven days, his therapy included combined pravastatin 20 mg and fenofibrate (160 mg, which was discontinued due to pains and weakness of muscles and significantly elevated CC to 7080 U/L (upper limit 200 U/L, but no significant deterioration of renal function was observed. Discontinuation of therapy resulted in CC level normalization and improvement of clinical condition. Conclusion Combined statin and fibrate therapy requires strict clinical control and monitoring of CK i transaminases. Four-time or higher increase of CK requires discontinuation of therapy. In addition, patients are advised to report immediately any pains in muscles, sensibility, weakness or cramps.

    Acne vulgaris is a common chronic inflammatory cutaneous disease involving the pilosebaceous unit. Its pathophysiology is multifactorial and complex, including obstruction of the pilosebaceous unit due to increased sebum production, abnormal keratinization, proliferation of Propionibacterium acnes (P. acnes), and inflammation. Topical agents are the most commonly used therapy for acne. First generation topicals mainly consist of single agent retinoids, benzoyl peroxide (BPO) and antibacterials that target comedones, P. acnes, and inflammation. Novel topical therapies include combination products with advanced vehicle formulations that target multiple acne pathophysiologies and offer simplified treatment regimes. For example, the combination of clindamycin and tretinoin in a unique vehicle formulation allows for progressive follicle penetration and decreased irritation, resulting in increased efficacy. Furthermore, adapalene or clindamycin with BPO combinations target comedones, inflammation, and P. acnes synergistically. These newer combination products have the potential to increase both efficacy and patient adherence when compared with single agent treatment.

    A number of reports indicating the growing acceptance of simultaneous therapy with multiple disease-modifying anti-rheumatic drugs (DMARDs), as well as the use of more aggressive treatment measures in the early phases of disease to combat rheumatoid arthritis (RA), have appeared during the last decade. However, only a few randomized controlled clinical trials have been conducted on the use of DMARD combinations in early RA. We review these trials in this article. In two separate one-year studies combination therapy with sulphasalazine (SSZ) and methotrexate (MTX) seemed to offer no benefits compared to either drug used as monotherapy. On the other hand, the DMARD combinations so far proven to be superior to single DMARDs have initially also included a corticosteroid component. In the COBRA study (Combinatietherapie Bij Reumatoide Artritis) the combination of SSZ (2 gm/day), MTX (7.5 mg/week for 40 weeks), and prednisolone (Prd) (initially 60 mg/day, tapered in 6 weekly steps to 7.5 mg/day and stopped after 28 weeks) compared to SSZ alone (2 gm/day) resulted in significantly better clinical outcomes at week 28. Although the difference in clinical response between the treatment arms was lost at week 58, the progression of joint damage remained statistically significantly slower at week 80 in the patients initially assigned to the combination therapy. Furthermore, in the FIN-RACo trial (Finnish Rheumatoid Arthritis Combination Therapy Trial), therapy using a "tailored-steps" strategy with SSZ (1-2 gm/day), MTX (7.5-1.5 mg/week), hydroxychloroquine (300 mg/day), and Prd (up to 10 mg/day) yielded a significantly increased remission rate and less peripheral joint damage at two years than the single DMARD treatment strategy (initially SSZ 2 gm/day), with or without Prd. Adverse effects in both study arms were comparable. Two additional preliminary reports (in abstract form) suggest that intensive local therapy in the form of intra-articular injections added to single or

    Therapeutic options for many infections are extremely limited and at crisis point. We run the risk of entering a second pre-antibiotic era. There had been no miracle drug for the patients infected by resistant microbial pathogens. Most of the very few new drugs under development have problems with their toxicity, or pharmacokinetics and pharmacodynamics. We are already decades behind in the discovery, characterization and development of new antimicrobials. In that scenario, we could not imagine surviving without newer and effective antimicrobial agents. Bacteria have been the champions of evolution and are still evolving continuously, where they pose serious challenges for humans. Along with the crisis of evolving resistance, the condition is made worst by the meager drug pipeline for new antimicrobials. Despite ongoing efforts only 2 new antibiotics (Telavancin in 2009 and Ceftaroline fosamil in 2010) have been approved since 2009 pipeline status report of Infectious Disease Society of America (IDSA). Recent approval of new combination based antiviral drugs such as Stribild (combination of four drugs for HIV treatment) and Menhibrix (combination vaccine to prevent meningococcal disease and Haemophilus influenzae type b in children) proves that combination therapy is still the most promising approach to combat the ever evolving pathogens. Combination therapy involves the drug repurposing and regrouping of the existing antimicrobial agents to provide a synergistic approach for management of infectious diseases. This review article is an effort to highlight the challenges in new drug development and potential of combination drug therapy to deal with them.

    Hypertension incurs a significant healthcare burden in Asia-Pacific countries, which have suboptimal rates of blood pressure (BP) treatment and control. A consensus meeting of hypertension experts from the Asia-Pacific region convened in Hanoi, Vietnam, in April 2013. The principal objectives were to discuss the growing problem of hypertension in the Asia-Pacific region, and to develop consensus recommendations to promote standards of care across the region. A particular focus was recommendations for combination therapy, since it is known that most patients with hypertension will require two or more antihypertensive drugs to achieve BP control, and also that combinations of drugs with complementary mechanisms of action achieve BP targets more effectively than monotherapy. The expert panel reviewed guidelines for hypertension management from the USA and Europe, as well as individual Asia-Pacific countries, and devised a treatment matrix/guide, in which they propose the preferred combination therapy regimens for patients with hypertension, both with and without compelling indications. This report summarizes key recommendations from the group, including recommended antihypertensive combinations for specific patient populations. These strategies generally entail initiating therapy with free drug combinations, starting with the lowest available dosage, followed by treatment with single-pill combinations once the BP target has been achieved. A single reference for the whole Asia-Pacific region may contribute to increased consistency of treatment and greater proportions of patients achieving BP control, and hence reducing hypertension-related morbidity and mortality.

    Full Text Available Kerry Reynolds, Sasmit Sarangi, Aditya Bardia, Don S Dizon Massachusetts General Hospital Cancer Center, Harvard Medical School, Boston, MA, USA Abstract: Trastuzumab (Herceptin, a monoclonal antibody directed against the human epidermal growth-factor receptor 2 (HER2, is the poster child for antibody-based targeted therapy in breast cancer. Pertuzumab, another humanized monoclonal antibody, binds to a different domain of HER2 and prevents the formation of HER2:HER3 dimers, which is the most potent heterodimer in the HER family. The combination of trastuzumab and pertuzumab has synergistic activity, and is associated with improved clinical outcomes. The US Food and Drug Administration (FDA approved pertuzumab in combination with trastuzumab-based chemotherapy originally as first-line therapy for metastatic HER2-positive breast cancer in 2012, and more recently as neoadjuvant therapy for localized disease in 2013. Pertuzumab is the first neoadjuvant drug to receive accelerated approval by the FDA based on pathological complete response as the primary end point. In this article, we review the mechanism of action, pharmacokinetics, clinical efficacy, safety, and current role of pertuzumab in the management of breast cancer, as well as ongoing clinical trials and future directions regarding the utility of pertuzumab as a personalized therapeutic option for HER2-positive breast cancer. In the coming years, we anticipate increased utilization of neoadjuvant trials for drug development, biomarker discovery, and validation, and envision conduct of personalized breast cancer clinics in which therapies will be routinely selected based on genetic alterations in the tumor. Regardless of the targeted therapy combinations employed based on tumor genomic profile, trastuzumab and pertuzumab will likely continue to form the backbone of the personalized regimen for HER2-positive breast cancer.

    Myocardial infarction, stroke, heart failure and end-stage renal disease have all been linked to inadequate control of blood pressure. Despite overwhelming evidence that uncontrolled hypertension is responsible for a sizeable number of adverse health-related outcomes, control of the disease remains considerably suboptimal. Available data demonstrate that in order to achieve adequate blood pressure control, a large number of patients require therapy with more than one medication. Fixed dose combination antihypertensive therapy has many advantages over other treatment options. Positive effects on blood pressure control, rates of adherence, adverse effects and cost have been identified. Amlodipine/benazepril (Lotrel), Novartis) is a fixed dose combination product indicated for the treatment of hypertension. Although not currently recommended as first-line therapy, studies confirm that this combination of a long-acting calcium antagonist and an angiotensin-converting enzyme (ACE) inhibitor possesses substantial blood pressure lowering capabilities. Whereas adverse events tend to become more frequent with increasing doses of antihypertensive monotherapy, the rate of adverse events attributed to amlodipine/benazepril in clinical trials often correlates with rates ascribed to placebo. Amlodipine/benazepril is capable of sustaining blood pressure control over a 24 h period and appears to be minimally affected by an occasional dose omission. Unlike the older calcium antagonists, amlodipine is unlikely to cause alterations in myocardial contractility. Additionally, the amlodipine/benazepril combination product costs less than the same therapy administered as the individual components. It is, therefore, reasonable to consider therapy with amlodipine/benazepril in appropriate patients after an adequate trial of antihypertensive monotherapy.

    2015-02-01

    There has been little improvement in septic shock mortality in the past 70 years, despite ever more broad-spectrum and potent antimicrobials. In the past, resuscitative elements have been the primary area of clinical septic shock management and research. The question of the optimal use of antimicrobial therapy was relatively ignored in recent decades. This review explores the pathophysiology of sepsis in an attempt to produce a better understanding and define key determinants of antimicrobial therapy response in septic shock. Optimizing existing antimicrobials delivery can drive significant improvements in the outcome of sepsis and septic shock. Inappropriate antimicrobial selection and dosing or delays in the administration substantially increase mortality and morbidity in life-threatening infections. Definitive combination therapy (where a pathogen known to be susceptible to a given agent is additionally covered by another agent) remains controversial. Although some in vitro studies, animal models, and clinical studies of infection including endocarditis, gram-negative bacteremia, and neutropenic infections have supported combination therapy, the potential clinical benefit in other severe infections has been questioned. Several meta-analyses have failed to demonstrate improvement of outcome with combination therapy in immunocompetent patients with sepsis and/or gram-negative bacteremia. These meta-analyses did not undertake subgroup analyses of the septic shock population. This article reviews the existing evidence supporting combination therapy for severe infections, sepsis, and septic shock.

    Fibromyalgia syndrome (FMS) is a chronic disorder that is characterized by widespread pain with localized tenderness. We aimed to investigate whether thermal therapy combining sauna therapy and underwater exercise improved pain, symptoms, and quality of life (QOL) in FMS patients. Forty-four female FMS patients who fulfilled the American College of Rheumatology (ACR) criteria received 12-week thermal therapy program comprising sauna therapy once daily for 3 days/week and underwater exercise once daily for 2 days/week. Pain, symptoms, and QOL were assessed using a pain visual analog scale (VAS), a fibromyalgia impact questionnaire (FIQ), and a short form 36-item questionnaire (SF-36), respectively. All of the patients reported significant reductions in pain and symptoms of 31-77% after the 12-week thermal therapy program, which remained relatively stable (28-68%) during the 6-month follow-up period (that is, the thermal therapy program improved both the short-term and the long-term VAS and FIQ scores). Improvements were also observed in the SF-36 score. Thermal therapy combining sauna therapy and underwater exercise improved the QOL as well as the pain and symptoms of FMS patients.

  8. Is fixed combination therapy appropriate for initial hypertension treatment?

    Elliott, William J

    2002-08-01

    Recent clinical trials in hypertension prove how seldom single drug therapy achieves target blood pressure (BP) and reduces cardiovascular morbidity and mortality. A natural response is the testing and marketing of fixed-dose combination products for hypertension, of which 14 have been approved in the United States since 1993. Currently, only five products are indicated by the Food and Drug Administration for initial therapy of hypertension; all include a diuretic. To achieve such an indication, studies must show not only safety and efficacy of the combination, but also BP lowering that is at least additive compared with the two agents given separately, as well as a "synergy" not present when each agent is given alone. Some advantages to initial combination therapy include greater BP reduction, improved adherence to pill taking, fewer side effects, and lower cost. The most likely candidates for initial combination therapy are patients with initial BP higher than 160/100 mm Hg, or those with a BP goal lower than the customary 140/90 mm Hg. These include patients with target organ damage, clinical cardiovascular disease, proteinuria, renal impairment, or diabetes mellitus. In many of these circumstances, an angiotensin converting enzyme inhibitor or angiotensin II receptor antagonist is frequently recommended; adding a diuretic or calcium antagonist to it is much more likely to result in achievement of the BP goal. More research is being done to explore the combination of not only two representatives from classes of conventional agents, but also other drugs that may help address the multiple manifestations of the "metabolic syndrome" that often accompanies hypertension.

    Objective:To investigate the effect of ganglioside and levodopa combined therapy on oxidative stress indexes, serum Parkinson related proteins and inflammatory factors of patients with Parkinson's disease.Methods:A total of 110 patients with Parkinson’s disease treated in our hospital were selected, and randomly divided to be the combination group and the control group, 55 cases for each. Patients in control group were treated with levodopa, patients in combination group were provided with ganglioside and levodopa combined therapy. Oxidative stress indexes, serum Parkinson related proteins and serum inflammatory factors for each group of patients were detected before and after treatment.Results:No statistical difference showed in oxidative stress indexes, serum Parkinson related proteins and serum inflammatory factors between the two groups of patients with Parkinson's disease (P>0.05). Compared with prior treatment, serum Parkinson related proteins (Csy C and S-100B), MDA and inflammatory factors (TNF-α, CRP, IL-6) after relevant treatment were significantly decreased, BDNF, IL-2 and oxidative stress indexes (NO, SOD and GSH) were significantly increased (P<0.05). Oxidative stress indexes (NO, SOD and GSH), BDNF, IL-2 in combination group were significantly higher than which in control group after treatment, serum Parkinson related proteins (Csy C and S-100B), inflammatory factors (TNF-α, CRP, IL-6) and MDA were significantly lower than in control group after treatment (P<0.05).Conclusions:Ganglioside and levodopa combination can significantly improve levels of oxidative stress indexes, serum Parkinson related proteins and serum inflammatory factors in patients with Parkinson’s disease. It has important clinical significance on therapy of patients with Parkinson’s disease.

    Treatment with checkpoint inhibitors has shown durable responses in a number of solid tumors, including melanoma, lung, and renal cell carcinoma. However, most breast cancers are resistant to monotherapy with checkpoint inhibitors. Radiation therapy (RT) has been shown to have a number of immunostimulatory effects, including priming the immune system, recruiting immune cells to the tumor environment, and altering the immunosuppressive effects of the tumor microenvironment. RT therefore represents a promising adjuvant therapy to checkpoint blockade in breast cancer. We review the data from the checkpoint blockade studies on breast cancer reported to date, the mechanisms by which RT potentiates immune responses, the preclinical and clinical data of checkpoint blockade and RT combinations, and the landscape of current clinical trials of RT and immune checkpoint inhibitor combinations in breast cancer. Clinical trials with checkpoint blockade therapy have demonstrated response rates of up to 19% in breast cancer, and many of the responses are durable. Preclinical data indicate that RT combined with checkpoint inhibition synergizes not only to enhance antitumor efficacy but also to induce responses outside of the radiation field. Thus multiple clinical trials are currently investigating the combination of checkpoint inhibition with RT. The use of combination strategies that incorporate chemotherapy and/or local strategies such as RT may be needed to augment responses to immune therapy in breast cancer. Preclinical and clinical results show that RT in combination with checkpoint blockade may be a promising therapeutic option in breast cancer. Copyright © 2017 Elsevier Inc. All rights reserved.

  16. Optimising treatment for COPD--new strategies for combination therapy.

    Science.gov (United States)

    Welte, T

    2009-08-01

    Chronic obstructive pulmonary disease (COPD) is a multi-component disease characterised by airflow limitation and airway inflammation. Exacerbations of COPD have a considerable impact on the quality of life, daily activities and general well-being of patients and are a great burden on the health system. Thus, the aims of COPD management include not only relieving symptoms and preventing disease progression but also preventing and treating exacerbations. Attention towards the day-to-day burden of the disease is also required in light of evidence that suggests COPD may be variable throughout the day with morning being the time when symptoms are most severe and patients' ability to perform regular morning activities the most problematic. While available therapies improve clinical symptoms and decrease airway inflammation, they do not unequivocally slow long-term progression or address all disease components. With the burden of COPD continuing to increase, research into new and improved treatment strategies to optimise pharmacotherapy is ongoing - in particular, combination therapies, with a view to their complementary modes of action enabling multiple components of the disease to be addressed. Evidence from recent clinical trials indicates that triple therapy, combining an anticholinergic with an inhaled corticosteroid and a long-acting beta(2)-agonist, may provide clinical benefits additional to those associated with each treatment alone in patients with more severe COPD. This article reviews the evidence for treatment strategies used in COPD with a focus on combination therapies and introduces the 3-month CLIMB study (Evaluation of Efficacy and Safety of Symbicort as an Add-on Treatment to Spiriva in Patients With Severe COPD) which investigated the potential treatment benefits of combining tiotropium with budesonide/formoterol in patients with COPD with regard to lung function, exacerbations, symptoms and morning activities.

Unlike other ARBs, azilsartan has no clinical data supporting improvement in cardiovascular outcomes, and is not approved for indications other than hypertension, which a select few other ARBs may be used for (eg, diabetic nephropathy and heart failure. Chlorthalidone is a longer acting thiazide-like diuretic that has been demonstrated to improve cardiovascular outcomes. Combination treatment with azilsartan/chlorthalidone is effective for reducing blood pressure. Compared to olmesartan/hydrochlorothiazide and azilsartan/hydrochlorothiazide combinations, azilsartan/chlorthalidone appears to be more efficacious for reducing blood pressure.Conclusions: Azilsartan/chlorthalidone can be considered an antihypertensive therapy option in patients for whom combination therapy is required (blood pressure >20 mmHg systolic or

    Effective treatment of high blood pressure represents a key strategy for reducing the burden of hypertension-related cardiovascular diseases, mostly myocardial infarction and stroke. Despite these well established concepts, however, hypertension remains poorly controlled, worldwide. In addition, treated hypertensive patients often remain at higher risk compared with the normotensive population, even when a satisfactory blood pressure control is achieved, due to the high or very high added cardiovascular risk profile observed in these patients. An emerging strategy to improve blood pressure control and achieve this unmet target for cardiovascular disease prevention in hypertensive patients is represented by a more extensive use of rational and effective combination therapies with respect to monotherapy. Such an approach has been recently proposed even as first-line strategy in hypertensive patients at high added cardiovascular risk or in those in whom strict blood pressure control is required. Within the possible antihypertensive drug combinations currently available for the clinical management of hypertension, those based on the association of drugs inhibiting the renin-angiotensin system and thiazide diuretics or calcium channel blockers have demonstrated to be effective and safe in lowering both systolic and diastolic blood pressure levels with a good tolerability profile. In addition, these strategies have provided evidence for effective cardiovascular protection compared with conventional antihypertensive therapies. Among the antihypertensive drugs able to counteract the deleterious effects of abnormal activation of the renin-angiotensin system, angiotensin II receptor blockers have demonstrated to provide better tolerability profile and greater cardiovascular protection on hypertension-related organ damage compared with ACE inhibitors in randomized controlled clinical trials, in the presence of similar antihypertensive efficacy and safety. In particular, these

    Carfilzomib is a proteasome inhibitor that binds selectively and irreversibly to the 20S proteasome, the proteolytic core particle within the 26S proteasome, resulting in the accumulation of proteasome substrates and ultimately growth arrest and apoptosis of tumor cells. The development and ultimate approval of this medication by regulatory agencies has been an important step toward improving clinical outcomes in multiple myeloma. Although initially approved as a single agent for the treatment of multiply relapsed and/or refractory myeloma, in the USA, it is now widely used in the early relapse setting in combination with lenalidomide and dexamethasone. Carfilzomib has also been studied in combination with second-generation immunomodulatory drugs, histone deacetylase inhibitors, alkylating agents and other novel medications. In this review article, we will discuss the efficacy, safety, tolerability and quality of life of carfilzomib-based combination therapies, as well as novel agents, for relapsed multiple myeloma.

    Full Text Available Preclinical work in murine models suggests that local radiotherapy plus intratumoral syngeneic DC injection can mediate immunologic tumor eradication. Radiotherapy affects the immune response to cancer, besides the direct impact on the tumor cells, and other ways to coordinate immune modulation with radiotherapy have been explored. We review here the potential for immune mediated anticancer activity of radiation on tumors. This is mediated by antigen acquisition and presentation by dendritic cells, and through changes of lymphocytes’ activity. Recent work has implemented the combination of external beam radiation (EBRT with intratumoral injection of dendritic cells (DC. This included a pilot study of coordinated intraprostatic, autologous DC injection together with radiation therapy with five HLA-A2(+ subjects with high-risk, localized prostate cancer; the protocol used androgen suppression, external beam radiation therapy (25 fractions, 45 Gy, DC injections after fractions 5, 15, and 25, and then interstitial radioactive implant. Another was a phase II trial using neo-adjuvant cell death-inducing EBRT plus intra-tumoral DC in soft tissue sarcoma, to test if this would increase immune activity toward soft tissue sarcoma associated antigens. Clinical experience using radiation therapies combined with other systemic immune treatments are additionally surveyed, including use of investigational recombinant vaccinia and fowlpox, interleukin-2, toll like receptor 9 (TLR9 agonists and lymphocyte checkpoint inhibitors directed at PD1 and at CTLA4.

    Full Text Available BACKGROUND: Cardiovascular disease management and prevention represent the leading cost driver in Italian healthcare expenditure. In order to reach the target blood pressure, a large majority of patients require simultaneous administration of multiple antihypertensive agents.OBJECTIVE: To assess the economic impact of the use of fixed dose combinations of antihypertensive agents, compared to the extemporary combination of the same principles.METHODS: A cost minimization analysis was conducted to determine the pharmaceutical daily cost of five fixed dose combinations (olmesartan 20 mg + amlodipine 5 mg, perindopril 5 mg + amlodipine 5 mg, enalapril 20 mg + lercanidipine 10 mg, felodipine 5 mg + ramipril 5 mg, and delapril 30 mg + manidipine 10 mg compared with extemporary combination of the same principles in the perspective of the Italian NHS. Daily acquisition costs are estimated based on current Italian prices and tariffs.RESULTS: In three cases the use of fixed‑dose combination instead of extemporary combination induces a lower daily cost. Fixed combination treatment with delapril 30 mg + manidipine 10 mg induces greater cost savings for the National Health System (95,47 €/pts/year, as compared to free drugs combination therapy.CONCLUSIONS: Compared with free drug combinations, fixed‑dose combinations of antihypertensive agents are associated with lower daily National Health Service acquisition costs.http://dx.doi.org/10.7175/fe.v14i4.886

    In recent years, the field of oncology has witnessed many breakthroughs in the treatment of advanced malignancies, particularly in patients with advanced melanoma. Targeted and immune checkpoint therapies have emerged as the primary treatment strategies for these patients. Molecular profiling of melanoma is incorporated into routine practice to identify potential therapeutic targets, and patients are offered either a targeted or immune checkpoint inhibitor therapy approach. Both strategies have limitations where not all patients experience durable responses. Preclinical data have demonstrated the ability of targeted therapy to enhance activity of effector T cells, reduce immunosuppressive cytokine production, and increase tumor cell antigen presentation, which can augment antitumor immunity. In vivo models have shown synergy with improved tumor control when targeted and immune checkpoint agents are combined. Therefore, combination strategies with targeted and immune checkpoint therapy may improve patient outcomes. Early clinical data with anti-programmed cell-death protein 1/programmed cell-death ligand 1 agents in combination with targeted inhibitors appear to have acceptable toxicity rates and the potential for enhanced antitumor activity. This review explores the current status of preclinical and clinical development for these combination approaches in patients with advanced melanoma.

    The advent of nanomedicine marks an unparalleled opportunity to advance the treatment of various diseases, including cancer. The unique properties of nanoparticles (NPs), such as large surface-to-volume ratio, small size, the ability to encapsulate various drugs, and tunable surface chemistry, give them many advantages over their bulk counterparts. This includes multivalent surface modification with targeting ligands, efficient navigation of the complex in vivo environment, increased intracellular trafficking, and sustained release of drug payload. These advantages make NPs a mode of treatment potentially superior to conventional cancer therapies. This review highlights the most recent developments in cancer treatment using NPs as drug delivery vehicles, including promising opportunities in targeted and combination therapy.

    Metastatic melanoma is an aggressive form of cancer characterised by poor prognosis and a complex etiology. Until 2010, the treatment options for metastatic melanoma were very limited. Largely ineffective dacarbazine, temozolamide or fotemustine were the only agents in use for 35 years. In recent years, the development of molecularly targeted inhibitors in parallel with the development of checkpoint inhibition immunotherapies has rapidly improved the outcomes for metastatic melanoma patients. Despite these new therapies showing initial promise; resistance and poor duration of response have limited their effectiveness as monotherapies. Here we provide an overview of the history of melanoma treatment, as well as the current treatments in development. We also discuss the future of melanoma treatment as we go beyond monotherapies to a combinatorial approach. Combining older therapies with the new molecular and immunotherapies will be the most promising way forward for treatment of metastatic melanoma. Copyright © 2015 Elsevier Ireland Ltd.

    2008-02-01

    Photodynamic therapy (PDT) is a promising treatment modality. It offers alternative options in the treatment of cancer and vascular diseases. In cancer treatment, PDT has been used primarily for localized superficial or endoluminal malignant and premalignant conditions. More recently, its application has also been expanded to solid tumors. However, its antitumor efficacy remains debatable and its acceptance still variable. Pre-clinical studies demonstrate that, in addition to the primary local cytotoxicity, PDT might induce secondary host immune responses, which may further enhance PDT's therapeutic effects on primary tumor as well as metastasis. Therefore, PDT-induced local and systemic antitumor immune response might play an important role in successful control of malignant diseases. Furthermore, PDT's antitumor efficacy might also be enhanced through an effective immunoadjuvant or immunomodulator. Our recent clinical data also indicate that improved clinical outcomes can be obtained by a combination of PDT and immunomodulation therapy for the treatment of pre-malignant skin diseases. For instance, the combination of topical ALA-PDT and Imiquimod is effective for the treatment of genital bowenoid papulosis. This presentation will also report our preliminary data in developing combination approaches of PDT and immunotherapy for actinic keratosis (AK), basal cell carcinomas (BCCs) and Bowen's disease.

The present study evaluated maximum diuresis while minimizing electrolyte imbalances, hemodynamic instability, and kidney dysfunction, to achieve a euvolemic state safely in a shorter period of time.Methods and results: A protocol of combined therapy with furosemide, metolazone, and spironolactone, with or without tolvaptan and acetazolamide, was used in 17 hospitalized patients with AHF. The mean number of days on combination diuretic protocol was 3.8 days. The mean daily fluid balance was 3.0±2.1 L negative. The mean daily urine output (UOP was 4.1±2.0 L (range 1.8–10.5 L. There were minimal fluctuations in serum electrolyte levels and serum creatinine over the duration of diuretic therapy. There was no statistically significant change in patients’ creatinine from immediately prior to therapy to the last day of therapy, with a mean increase in creatinine of 0.14 mg/dL (95% CI −0.03, +0.30, p=0.10.Conclusion: Our strategy of treating AHF by achieving high UOP, while maintaining stable electrolytes and creatinine in a short period to euvolemic state, is safe.

    AIM: To assess the efficacy of triple therapy (peginterferon or high dose standard interferon, plus ribavirin and amantadine) in nonresponders to prior combination therapy.METHODS: A total of 196 patients were enrolled in a multicenter, open, randomized study. Patients were given 180 μg/wk of peginterferon-alpha-2a (40 kD) plus ribavirin (800-1000 mg/d) and amantadine (200 mg/d)for 48 wk (group A) or interferon-alpha-2a (6 MU/d for 4 wk, 3 MU/d for 20 wk, and 3 MU tiw for 24 wk) plus ribavirin (800-1000 mg/d) and amantadine (200 mg/d)for 48 wk (group B).RESULTS: Overall sustained virologic response (SVR)was 26.6% (32.1% and 19.5% in group A and B, P =0.057). Baseline ALT >120 UI/L (OR 2.4; 95% CI:1.11to 5.20; P = 0.026) and HCV RNA negativity after 12 wk (OR 8.7; 95% CI: 3.87 to 19.74; P < 0.0001)were independently associated with SVR. Therapy discontinuation occurred less frequently in patients treated with peginterferon than standard interferon (P =0.036).CONCLUSION: More than 25% of nonresponders to combination therapy can eradicate HCV infection when retreated with triple therapy, especially if they have a high baseline ALT and are treated with pegylated interferon.

    There is increasing urgency in the battle against drug-resistant bacterial pathogens, and this public health crisis has created a desperate need for novel antimicrobial agents. Recombinant human lysozyme represents one interesting candidate for treating pulmonary infections, but the wild type enzyme is subject to electrostatic mediated inhibition by anionic biopolymers that accumulate in the infected lung. We have redesigned lysozyme’s electrostatic potential field, creating a genetically engineered variant that is less susceptible to polyanion inhibition, yet retains potent bactericidal activity. A recent publication demonstrated that the engineered enzyme outperforms wild type lysozyme in a murine model of Pseudomonas aeruginosa lung infection. Here, we expand upon our initial studies and consider dual therapies that combine lysozymes with an antimicrobial peptide. Consistent with our earlier results, the charge modified lysozyme combination outperformed its wild type counterpart, yielding more than an order-of-magnitude reduction in bacterial burden following treatment with a single dose.

    Colorectal cancer remains one of the major causes of cancer death worldwide. During the past years, the development of new effective treatment options has led to a considerable improvement in the outcome of this disease. The advent of agents such as capecitabine, irinotecan, oxaliplatin, cetuximab and bevacizumab has translated into median survival times in the range of 2 years. Intense efforts have focused on identifying novel agents targeting specific growth factor receptors, critical signal transduction pathways or mediators of angiogenesis. In addition, several clinical trials have suggested that some of these molecularly targeted drugs can be safely and effectively used in combination with conventional chemotherapy. In this article we review various treatment options combining cytotoxic and targeted therapies currently available for patients with metastatic colorectal cancer.

    Anthracyclic antibiotics, of which adriamycin is representative, have the ability to bind to cellular DNA and thereby interfere with the X ray repair process. When radiation survival curves of tissue cultures were studied, increased cell-killing was noted in those cultures with adriamycin over those without the drug. The mechanism by which this occurs may be related to a reduced rate of DNA strand break rejoining, as demonstrated by use of alkaline sucrose gradient techniques. A preliminary clinical Phase I study, in which patients with advanced gynecologic malignancy were treated by simultaneous adriamycin and X radiation, suggests that combined therapy is well-tolerated, and that such combinations may prove useful in selected patients.

The hydrophobic heat shock protein 90 inhibitor 17-allylamino-17-demethoxygeldanamycin and the photosensitizer cyanine dye infrared-780 were loaded into the core of the micelles to achieve both chemotherapy and photothermal therapy simultaneously at the tumor site. The release of the drug could be controlled by varying the temperature due to the thermosensitive nature of the micelles. The micelles were less than 200 nm in size, and the drug encapsulation efficiency was >50%. The critical micelle concentrations were small enough to allow micelle stability upon dilution.

    Upon its inception, repetitive transcranial magnetic stimulation (rTMS) was delivered at rest, without regard to the potential impact of activity occurring during or around the time of stimulation. rTMS was considered an experimental intervention imposed on the brain; therefore, the myriad features that might suppress or enhance its desired effects had not yet been explored. The field of rTMS has since grown substantially and therapeutic benefits have been reported, albeit with modest and inconsistent improvements. Work in this field accelerated following approval of a psychiatric application (depression), and it is now expanding to other applications and disciplines. In the last decade, experimental enquiry has sought new ways to improve the therapeutic benefits of rTMS, intended to enhance underlying brain reorganization and functional recovery by combining it with behavioral therapy. This concept is appealing, but poorly defined and requires clarity. We provide an overview of how combined rTMS and behavioral therapy has been delineated in the literature, highlighting the diversity of approaches. We outline a framework for study design and reporting such that the effects of this emerging method can be better understood.

    We performed preoperative combined therapy using nedaplatin (CDGP) and radiation in 12 patients with squamous cell carcinoma originating from the oral cavity and maxillary sinus, and examined for any adverse events that may have occurred during this therapeutic regimen. Regarding the irradiation, external irradiation utilizing a 6 MV linac (linear accelerator) at a dose of 2.0 Gy/day was performed 5 times a week, with the target total radiation dose set at 40 Gy. In addition, CDGP was intravenously administered 30 minutes before irradiation at a dose of 5 mg/m{sup 2}/day. Mucositis was observed in all 12 subjects, however, the severity was observed to be grade 1-2 with no major differences in comparison to the patients given standard radiation monotherapy. Two subjects developed grade 3 leucopenia and were thus given granulocyte colony stimulating factor (G-CSF). In addition, grade 2 and grade 3 thrombocytopenia were both observed in one subject each. The subject with grade 3 thrombocytopenia required a platelet transfusion during surgery. No marked changes in serum creatinine levels were noted. These findings are therefore considered to provide evidence supporting the safety of this combination therapy. (author)

    Pancreatic cancer is the only human malignancy for which patients' survival has not improved substantially during the past 30 years. Despite advances in the comprehension of the molecular mechanisms underlying pancreatic carcinogenesis, current systemic treatments offer only a modest benefit in tumor-related symptoms and survival. Over the past decades, gemcitabine and its combination with other standard cytotoxic agents have been the reference treatments for advanced pancreatic cancer patients. The recent introduction of the three-drug combination regimen FOLFIRINOX or the new taxane nab-paclitaxel represent key advances for a better control of the disease. Novel agents targeting molecular mechanisms involved in cancer development and maintenance are currently under clinical investigation. This review describes the most important findings in the field of systemic combination therapies for the treatment of pancreatic cancer. We discuss the emerging evidences for the clinical activity of combination treatments with standard chemotherapy plus novel agents targeting tumor cell-autonomous and tumor microenvironment signaling pathways. We present some of the most important advances in the comprehension of the molecular mechanisms responsible for the chemoresistance of pancreatic cancer and the emerging therapeutic targets to overcome this resistance.

    Epigenetics is a relatively recent field of molecular biology that has arisen over the past 25 years. Cancer is now understood to be a disease of widespread epigenetic dysregulation that interacts extensively with underlying genetic mutations. The development of drugs targeting these processes has rapidly progressed; with several drugs already FDA approved as first-line therapy in hematological malignancies. Gastrointestinal (GI) cancers possess high degrees of epigenetic dysregulation, exemplified by subtypes such as CpG island methylator phenotype (CIMP), and the potential benefit of epigenetic therapy in these cancers is evident. The application of epigenetic drugs in solid tumors, including GI cancers, is just emerging, with increased understanding of the cancer epigenome. In this review, we provide a brief overview of cancer epigenetics and the epigenetic targets of therapy including deoxyribonucleic acid (DNA) methylation, histone modifications, and chromatin remodeling. We discuss the epigenetic drugs currently in use, with a focus on DNA methyltransferase (DNMT) and histone deacetylase (HDAC) inhibitors, and explain the pharmacokinetic and mechanistic challenges in their application. We present the strategies employed in incorporating these drugs into the treatment of GI cancers, and explain the concept of the cancer stem cell in epigenetic reprogramming and reversal of chemo resistance. We discuss the most promising combination strategies in GI cancers including: (1) epigenetic sensitization to radiotherapy, (2) epigenetic sensitization to cytotoxic chemotherapy, and (3) epigenetic immune modulation and priming for immune therapy. Finally, we present preclinical and clinical trial data employing these strategies thus far in various GI cancers including colorectal, esophageal, gastric, and pancreatic cancer. PMID:27366224

    Full Text Available Benjamin J EpsteinDepartments of Pharmacotherapy and Translational Research and Medicine, Colleges of Pharmacy and Medicine, University of Florida, Gainesville, Florida, USA and East Coast Institute for Research, Jacksonville, Florida, USAAbstract: Combination therapy is necessary for most patients with hypertension, and agents that inhibit the renin-angiotensin-aldosterone system (RAAS are mainstays in hypertension management, especially for patients at high cardiovascular and renal risk. Single blockade of the RAAS with an angiotensin-converting enzyme (ACE inhibitor or angiotensin receptor blocker (ARB confers some cardiorenal protection; however, these agents do not extinguish the RAAS as evidenced by a reactive increase in plasma renin activity (PRA, a cardiovascular risk marker, and incomplete cardiorenal protection. Dual blockade with an ACE inhibitor and an ARB offers no additional benefit in patients with hypertension and normal renal and left ventricular function. Indeed, PRA increases synergistically with dual blockade. Aliskiren, the first direct renin inhibitor (DRI to become available has provided an opportunity to study the merit of DRI/ARB combination treatment. By blocking the first and rate-limiting step in the RAAS, aliskiren reduces PRA by at least 70% and buffers the compensatory increase in PRA observed with ACE inhibitors and ARBs. The combination of a DRI and an ARB or an ACE inhibitor is an effective approach for lowering blood pressure; available data indicate that such combinations favorably affect proteinuria, left ventricular mass index, and brain natriuretic peptide in patients with albuminuria, left ventricular hypertrophy, and heart failure, respectively. Ongoing outcome studies will clarify the role of aliskiren and aliskiren-based combination RAAS blockade in patients with hypertension and those at high cardiorenal risk.Keywords: aliskiren, valsartan, single-pill combination, hypertension, renin

    This preliminary study was performed to investigate the efficacy of the combined therapy of orbital cobalt irradiation and oral prednisolone administration, and pulse therapy, for Graves' ophthalmopathy. The combined therapy was undergone according to procedure of Bartalena et al. (1983) in 5 patients. Excellent or good response to combined therapy were shown by 3 patients with short-standing ocular symptoms (3-4 months), but not by 2 patients with long-standing ocular symptoms (12-13 months). Pulse therapy was performed on 2 patients who showed no improvement from combined therapy, and on a patient who had acute onset of opthalmopathy. One gram of methylprednisolone sodium succinate was given intravenously daily for 3 successive days. This infusion procedure was repeated 3 to 4 times at intervals of 1 week. One of 2 patients who showed no improvement from combined therapy also had no response to pulse therapy. The other 2 patients showed a good response to pulse therapy and showed no relapse of ophthalmopathy for 10 and 8 months, respectively. These data emphasize the need for early immuno-suppressive therapy for Graves' ophthalmopathy. Pulse therapy may be employed in patients who show no response to other therapy method.

    Malignant pleural mesothelioma (MPM) is a relative rare but highly aggressive neoplasm which is associated with asbestos exposure in most patients. The majority of patients are diagnosed in advanced stages so patients neither benefit from chemotherapy (e.g. pemetrexed-platinum combination) nor from surgery. It has been reported that cellular-mesenchymal to epithelial transition factor (MET) and epidermal growth factor receptor (EGFR) were critical for MPM cell proliferation. Moreover, targeting MET and EGFR drugs have gained promising results on anti-tumor therapy. Here, a striking difference in overall survival was observed between the MET and EGFR co-expression group (median survival time = 13.5 months) and non-co-expression group (median survival time = 20.5 months). In addition, treatment with combination of crizotinib and afatinib showed stronger inhibition on cell proliferation of MPM than the treatment by either one in vitro and in vivo. In conclusion, our data illustrated that crizotinib combined with afatinib may be a potentially effective strategy for treating MPM patients with over-expression of MET and EGFR.

    Full Text Available Raphael E Steiner, Elisabet E Manasanch Department of Lymphoma and Myeloma, The University of Texas MD Anderson Cancer Center, Houston, TX, USA Abstract: Carfilzomib is a proteasome inhibitor that binds selectively and irreversibly to the 20S proteasome, the proteolytic core particle within the 26S proteasome, resulting in the accumulation of proteasome substrates and ultimately growth arrest and apoptosis of tumor cells. The development and ultimate approval of this medication by regulatory agencies has been an important step toward improving clinical outcomes in multiple myeloma. Although initially approved as a single agent for the treatment of multiply relapsed and/or refractory myeloma, in the USA, it is now widely used in the early relapse setting in combination with lenalidomide and dexamethasone. Carfilzomib has also been studied in combination with second-generation immunomodulatory drugs, histone deacetylase inhibitors, alkylating agents and other novel medications. In this review article, we will discuss the efficacy, safety, tolerability and quality of life of carfilzomib-based combination therapies, as well as novel agents, for relapsed multiple myeloma.

    Globally, 240,000 infants are newly infected with HIV-1 each year and 3.2 million children are living with the infection. Combination antiretroviral therapy (cART) has reduced HIV-1-related disease and mortality in children but is not curative owing to the early generation of a latent reservoir of long-lived memory CD4(+) T cells bearing replication-competent HIV-1 provirus integrated into cellular DNA. This review focuses on recent advances in our understanding of the establishment of HIV-1 persistence in children and how early initiation of cART in the setting of the developing infant immune system limits the formation of the long-lived latent CD4(+) cell reservoir that remains a barrier to remission or cure.

    Current chemotherapeutic approaches for cancer are in part limited by the inability of drugs to destroy neoplastic cells within poorly vascularized compartments of tumors. We have here systematically assessed anaerobic bacteria for their capacity to grow expansively within avascular compartments of transplanted tumors. Among 26 different strains tested, one (Clostridium novyi) appeared particularly promising. We created a strain of C. novyi devoid of its lethal toxin (C. novyi-NT) and showed that intravenously injected C. novyi-NT spores germinated within the avascular regions of tumors in mice and destroyed surrounding viable tumor cells. When C. novyi-NT spores were administered together with conventional chemotherapeutic drugs, extensive hemorrhagic necrosis of tumors often developed within 24 h, resulting in significant and prolonged antitumor effects. This strategy, called combination bacteriolytic therapy (COBALT), has the potential to add a new dimension to the treatment of cancer.

    Locally advanced rectal cancer has been a surgical challenge because of fixation of the primary tumor to the boney pelvis or to other pelvic soft tissues. During a 12-month period seven patients with locally advanced adenocarcinoma of the rectum were treated preoperatively with simultaneous pelvic irradiation (4500-5040 cGy) and infusion chemotherapy (5-fluorouracil 1000 mg per m2 per day over 96 hours and mitomycin 10 mg per m2. Tolerance was reasonable and all patients underwent successful resection of the primary lesion. Two patients had a complete response to preoperative combined modality therapy with no cancer found in the surgical specimen. With a short follow-up period, all patients have experienced satisfactory healing and none have suffered local or distant recurrence. The results of this limited series are encouraging for future clinical trials.

    For the development of new controlled drug delivery systems, the application of combination therapy using angiogenesis inhibitor and tumor static agents has drawn great attention. This approach would be very beneficial for cancer treatment especially when a new drug deliver system utilizing biodegradable polymers is developed. Therefore, the present study for the combination therapy of angiogenesis inhibitor and chemotherapeutic agents was to carry out prior to the development of the novel drug delivery. In present study, the ability of inhibition on cell growth was investigated with treatment of anti-angiogenetic agent and anticancer agent. Thalidomide was used as an antivasculatory agents and Doxorubicine was treated as a chemotherapeutic agent. To demonstrate apoptotic process in in-vitro study, TUNEL assay was carried out. Also, the alteration of p53 level was examined by using western blotting. For the cell lines, NIH:OVCAR3, MKN45, SNU719, C6, L929, T98G, Hep3B and Calu6 were applied. Results showed that Thalidomide inhibited cell growth in tumor cell lines in a dose-dependent manner and Doxorubicin as well. A significant synergistic effect on the apoptotic was noticed in the combination treatment of Thalidomide and Doxorubicin compared to a single treatment of either drug. Therefore, it can be concluded that the mechanism of cytotoxicity was due to the enhancement of apoptosis in early cell death with combination treatment in tumor cell lines.

  12. Quantifying the pharmacology of antimalarial drug combination therapy

    Most current antimalarial drugs are combinations of an artemisinin plus a ‘partner’ drug from another class, and are known as artemisinin-based combination therapies (ACTs). They are the frontline drugs in treating human malaria infections. They also have a public-health role as an essential component of recent, comprehensive scale-ups of malaria interventions and containment efforts conceived as part of longer term malaria elimination efforts. Recent reports that resistance has arisen to artemisinins has caused considerable concern. We investigate the likely impact of artemisinin resistance by quantifying the contribution artemisinins make to the overall therapeutic capacity of ACTs. We achieve this using a simple, easily understood, algebraic approach and by more sophisticated pharmacokinetic/pharmacodynamic analyses of drug action; the two approaches gave consistent results. Surprisingly, the artemisinin component typically makes a negligible contribution (≪0.0001%) to the therapeutic capacity of the most widely used ACTs and only starts to make a significant contribution to therapeutic outcome once resistance has started to evolve to the partner drugs. The main threat to antimalarial drug effectiveness and control comes from resistance evolving to the partner drugs. We therefore argue that public health policies be re-focussed to maximise the likely long-term effectiveness of the partner drugs. PMID:27604175

    There has been a relentless increase in resistance of malaria parasites to conventional antimalarial drugs, including chloroquine, sulfadoxine-pyrimethamine and mefloquine. In response to this situation, short-course artemisinin-based combination therapies (ACTs) have been developed. The World Health Organization has endorsed ACT as first-line treatment where the potentially life-threatening parasite Plasmodium falciparum is the predominant infecting species. ACTs combine the rapid schizontocidal activity of an artemisinin derivative (artesunate, artemether or dihydroartemisinin) with a longer-half-life partner drug. Although the use of chloroquine and sulfadoxine-pyrimethamine as partners in ACT improves their efficacy, this may only have value as a short-term measure in patients with a degree of immunity to malaria. Alternative currently available partner drugs include mefloquine, lumefantrine and piperaquine. Artesunate-mefloquine is highly effective but is expensive and side effects (mainly neurotoxicity) can be problematic. Artemether-lumefantrine, the only ACT available in Australia, appears less effective than artesunate-mefloquine and needs to be administered with food to ensure adequate bioavailability. Dihydroartemisinin-piperaquine is highly effective, well tolerated and relatively inexpensive. The goal of potent, safe, easy-to-administer and inexpensive ACTs may see trioxolanes in place of artemisinin derivatives, as well as novel partner drugs such as pyronaridine or naphthoquine, in the future.

    The emergence of malaria parasite strains resistant to practically all the antimalarial drugs in clinical use is now making itnecessary to discover and develop both new antimalarial drugs and treatments. Recent advances in molecular techniques along withthe availability of genome sequence ofPlasmodiumfalciparum may provide a wide range of novel targets in metabolic pathways likeisoprenoid biosynthesis, fatty acid biosynthesis and heme biosynthesis in the apicoplast of Plasmodiurn. On the other hand, thecombination therapy approach (currently used to retard the selection of parasite strains resistant to individual components of acombination of drugs) has proved to be a success in the combination of sulphadoxine and pyrimethamine, which targets two differentsteps in the folate pathway of malaria parasite. However, after the success of this therapeutic combination, the efficacy of othercombinations of drugs which target different enzymes in a particular metabolic pathway has, apparently, not been reported. Therefore,herein, we review various drug targets so far discovered in apicoplast-related anabolic pathways, especially, with a sharper focus onthe possibility to target more than one enzyme at a time in a particular metabolic pathway of malaria parasites.

Multivariate logistic regression compared treatment groups based on the likelihood of achieving ≥95% adherence, with sensitivity analyses using alternative thresholds. MPR was assessed as a continuous variable using multivariate linear regression. Covariates included age, gender, insurance payer type, year of study drug initiation, presence of mental health and substance abuse disorders, and third agent class. The study sample consisted of 650 FDC and 1947 NRTI Combo patients. Unadjusted mean adherence to the third agent was higher in the FDC group than the NRTI Combo group (0.92 vs 0.85; P < 0.0001. In regression analyses, FDC patients were 48% and 39% more likely to achieve 95% and 90% third agent adherence, respectively (P ≤ 0.03. None of the other MPR specifications achieved comparable results. Among managed care patients, use of an FDC appears to substantially improve adherence to a third regimen component and thus the likelihood of achieving the accepted standard for adherence to HIV therapy of 95%.Keywords

    Full Text Available Objective: To explore the effect of cognitive behavioral therapy (CBT in combination with systemic family therapy (SFT on mild to moderate postpartum depression and sleep quality. Methods: 249 primiparous women with mild to moderate postpartum depression were recruited and randomly assigned to a control group (n=128, which received conventional postpartum care, or to a psychological intervention group (n=121, which received conventional postpartum care combined with psychological intervention. The Edinburgh Postnatal Depression Scale (EPDS and Pittsburgh Sleep Quality Index (PSQI were employed to evaluate depression and sleep quality, respectively. Results: 104 patients in the intervention group and 109 in the control group completed the study. After intervention, the EPDS score, PSQI score, sleep quality score, sleep latency score, sleep duration score, habitual sleep efficiency score, sleep disturbance score, and daytime dysfunction score were significantly lower in the intervention group than in the control group. The EPDS and PSQI scores of each group at different time points after intervention were markedly decreased compared with those before intervention, and the reduction in the intervention group was more evident than that in the control group. Conclusion: CBT in combination with SFT can improve depression and sleep quality in patients with mild to moderate postpartum depression.

    Full Text Available Purpose: We evaluated the effectiveness of combining behavioral therapy, pharmacologic therapy and endoscopic hydrodistension for treating painful bladder syndrome / interstitial cystitis (PBS/IC. Materials and Methods: Twenty-five patients with PBS/IC were prospectively enrolled in a pilot multimodal behavioral, pharmacologic and endoscopic treatment protocol. Behavioral modification included diet recommendations, fluid restriction to 64 oz. /day, progressive timed voiding and Kegel exercises. Oral pharmacologic therapy consisted of daily doses of macrodantin 100 mg, hydroxyzine 10-20 mg and urised 4 tablets. Patients underwent endoscopic bladder hydrodistention under anesthesia at least 2 weeks after protocol enrollment. Behavioral and pharmacological treatments were continued after the hydrodistention. O'Leary-Sant questionnaire scores were recorded before starting the protocol, after pharmacologic/behavioral therapy, 2 months post-hydrodistension, and at scheduled follow-up. Results: Eighteen patients (72% completed the pilot multimodal treatment protocol and were followed for a mean of 10.2 months. All patients were female with a median age of 36.3 years and had mean bladder capacity under anesthesia of 836 milliliters. Mean O'Leary-Sant symptom index scores for baseline symptoms, after behavioral/pharmacologic treatment, post-hydrodistension and during follow up were 12.5, 8.6, 7.0, and 6.7 (p < 0.05. Mean O'Leary-Sant problem index scores for baseline, after behavioral/pharmacologic treatment, post-hydrodistention and during follow up were 12.7, 8.9, 6.7, and 7.7 (p < 0.05. Conclusion: Our pilot multimodal protocol of behavioral modification, pharmacologic therapy and endoscopic hydrodistention demonstrated a significant progressive improvement in PBS/IC quality of life scores, compared to a pre-treatment baseline. These results should be validated in a larger, placebo controlled trial.

    Poor quality antimalarials, including falsified, substandard, and degraded drugs, are a serious health concern in malaria-endemic countries. Guidelines are lacking on how to distinguish between substandard and degraded drugs. “Forced degradation” in an oven was carried out on three common artemisinin-based combination therapy (ACT) brands to detect products of degradation using liquid chromatography mass spectrometry and help facilitate classification of degraded drugs. “Natural aging” of 2,880 tablets each of ACTs artemether/lumefantrine and artesunate/amodiaquine was undertaken to evaluate their long-term stability in tropical climates. Samples were aged in the presence and absence of light on-site in Ghana and in a stability chamber (London), removed at regular intervals, and analyzed to determine loss of the active pharmaceutical ingredients (APIs) over time and detect products of degradation. Loss of APIs in naturally aged tablets (both in Ghana and the pharmaceutical stability chamber) was 0–7% over 3 years (∼12 months beyond expiry) with low levels of degradation products detected. Using this developed methodology, it was found that a quarter of ACTs purchased in Enugu, Nigeria (concurrent study), that would have been classified as substandard, were in fact degraded. Presence of degradation products together with evidence of insufficient APIs can be used to classify drugs as degraded. PMID:26951346

    To evaluate the efficacy and safety of acupuncture combined with traction therapy for lumbar disc herniation, providing the basis for future research strategies. Randomized control trials. (RCT) of acupuncture combined with traction therapy for lumber disc herniation at home and abroad from 2000 to 2013 were searched, analysis and evaluation of literature and strength of evidence were based on the principles and methods of Evidence-based Medicine. The total effective rate and curative rate were considered as primary outcome measures; pain improvement, quality of life, relapse rate and adverse effects were considered as secondary outcome measures. Seventeen RCTs were identified, Meta-analysis showed that (1) total effective rate and curative rate: acupuncture combined with traction therapy was better than single therapy (acupuncture or traction); (2) pain improvement: acupuncture combined with traction therapy was better than traction therapy; (3) relapse rate: current evidence could not support the conclusion that acupuncture combined with traction therapy was better than traction therapy. Acupuncture combined with traction therapy for lumbar disc herniation was effective. However, the included studies were with high risk of bias, important outcome measures such as quality of life, relapse rate and adverse effects were not found in most of the studies. Current evidence has not yet been able to fully reflect acupuncture combined with traction therapy for lumbar disc herniation is better than single therapy, so more RCTs of higher quality are needed to further confirm its efficacy and safety.

    Access to combination antiretroviral therapy (cART) has decreased mortality in HIV-positive people. We aimed to estimate the expected additional years of life in HIV-positive Thai people after starting cART through the National AIDS Program (NAP), administered by the Thai National Health Security Office (NHSO). The NHSO database collects characteristics of all Thai HIV-infected patients through the National AIDS Program, including linkage with the National Death Registry for vital status. This study included patients aged ≥15 years at cART initiation between 2008 and 2014. The abridged life table method was used to construct life tables stratified by sex and baseline CD4(+) T-cell count. Life expectancy was defined as the additional years of life from age at starting cART. 201,688 eligible patients were included in analyses, contributing 618,837 person-years of follow-up. Median CD4(+) T-cell count was 109 cells/mm(3) and median age 37 years. The overall life expectancy after cART initiation at age 20 was 25.4 (95% CI, 25.3, 25.6) years and 20.6 (95% CI, 20.5, 20.7) at age 35 years. Life expectancy at baseline CD4(+) T-cell count ≥350 cells/mm(3) was 51.9 (95% CI, 51.0, 52.9) years for age 20 years and 43.2 (95% CI, 42.4, 44.1) years for age 35 years, close to life expectancy in the general Thai population. Increasing life expectancy with higher baseline CD4(+) T-cell counts supports the guideline recommendations to start cART irrespective of CD4(+) T-cell count. These results are beneficial to forecast the treatment cost and develop health policies for people living with HIV in Thailand and Asia.

  3. Melanoma: A model for testing new agents in combination therapies

    Streicher Howard Z

    2010-04-01

    Full Text Available Abstract Treatment for both early and advanced melanoma has changed little since the introduction of interferon and IL-2 in the early 1990s. Recent data from trials testing targeted agents or immune modulators suggest the promise of new strategies to treat patients with advanced melanoma. These include a new generation of B-RAF inhibitors with greater selectivity for the mutant protein, c-Kit inhibitors, anti-angiogenesis agents, the immune modulators anti-CTLA4, anti-PD-1, and anti-CD40, and adoptive cellular therapies. The high success rate of mutant B-RAF and c-Kit inhibitors relies on the selection of patients with corresponding mutations. However, although response rates with small molecule inhibitors are high, most are not durable. Moreover, for a large subset of patients, reliable predictive biomarkers especially for immunologic modulators have not yet been identified. Progress may also depend on identifying additional molecular targets, which in turn depends upon a better understanding of the mechanisms leading to response or resistance. More challenging but equally important will be understanding how to optimize the treatment of individual patients using these active agents sequentially or in combination with each other, with other experimental treatment, or with traditional anticancer modalities such as chemotherapy, radiation, or surgery. Compared to the standard approach of developing new single agents for licensing in advanced disease, the identification and validation of patient specific and multi-modality treatments will require increased involvement by several stakeholders in designing trials aimed at identifying, even in early stages of drug development, the most effective way to use molecularly guided approaches to treat tumors as they evolve over time.

    Full Text Available Calreticulin is recognized as one of pivotal damage-associated molecular pattern (DAMP molecules alerting the host of the presence of distressed cells. In this role, calreticulin becomes exposed on the surface of tumor cells treated by several types of cancer therapy including photodynamic therapy (PDT. The goal of the present study was to examine the potential of externally added calreticulin for augmenting antitumor effect mediated by PDT. Recombinant calreticulin was found to bind to mouse SCCVII tumor cells treated by PDT. Compared to the outcome with PDT alone, cure-rates of SCCVII tumors grown in immunocompetent C3H/HeN mice were elevated when calreticulin (0.4 mg/mouse was injected peritumorally immediately after PDT. Such therapeutic gain with PDT plus calreticulin combination was not obtained with SCCVII tumors growing in immunodeficient NOD-scid mice. In PDT vaccine protocol, where PDT-treated SCCVII cells are used for vaccination of SCCVII tumor-bearing mice, adding recombinant calreticulin to cells before their injection produced improved therapeutic effect. The expression of calreticulin gene was reduced in PDT-treated cells, while no changes were observed with the expression of this gene in tumor, liver, and spleen tissues in PDT vaccine-treated mice. These findings reveal that externally added recombinant calreticulin can boost antitumor responses elicited by PDT or PDT-generated vaccines, and can thus serve as an effective adjuvant for cancer treatment with PDT and probably other cancer cell stress-inducing modalities.

    An analysis of literature shows that there is still little evidence concerning the efficacy of electroconvulsive therapy (ECT) combined with antipsychotic therapy in a group of treatment-resistant schizophrenia patients. More precisely, its influence on cognitive functions is still equivocal. The aim of this study was to assess the influence of ECT combined with antipsychotic therapy on working memory, attention, and executive functions in a group of treatment-refractory schizophrenia patients. Twenty-seven patients completed the study: 14 men and 13 women, aged 21 to 55 years (mean age, 32.8 years), diagnosed with treatment-resistant schizophrenia. Each patient underwent a course of ECT sessions and was treated with antipsychotic medications. Before the ECT and within 3 days after the last ECT session, the participants were assessed with the following neuropsychological tests: Trail Making Test (TMT) and Wisconsin Cart Sorting Test (WCST). There were no significant differences in the TMT and WCST results after combined ECT and antipsychotic therapy in treatment-refractory schizophrenia patients. According to the results of the neuropsychological tests, there was no decline in attention, executive functions, or working memory. The current study shows no significant difference in attention, working memory, or executive functions after treatment with a combination of electroconvulsive and antipsychotic therapy. This suggests that combined electroconvulsive therapy may not have a negative influence on the neuropsychological functioning of patients with treatment resistant schizophrenia.

    Peginterferon and ribavirin combination therapy for the treatment of hepatitis C virus (HCV) is well known to be associated with significant adverse effects. Sensorineural hearing loss, that in most cases is unilateral, has been reported as a consequence of therapy with both non-pegylated and pegylated interferon (pegIFN) but is not a well-known adverse effect. We report a 45-year-old Caucasian woman who developed acute sensorineural hearing loss 2 mo after starting therapy with pegIFN-α 2b and ribavirin for the treatment of chronic HCV, genotype 1a. She did not report the hearing loss to the hepatitis clinic until L mo,later whereupon therapy was promptly discontinued.Although her serum alanine aminotransferase (ALT)normalized and her HCV-RNA became undetectable after 12 wk of pegIFN and ribavirin therapy, after discontinuation,her HCV-RNA became detectable with significant elevations of serum ALT. Four months after initial discontinuation,the patient re-commenced pegIFN and ribavirin combination therapy. After 44 of 48 wk of therapy, the patient's liver biochemistry has normalized and the HCV-RNA is undetectable. She has not developed worsening of her hearing loss and hearing on the left-side is unaffected.Both patients and physicians should be aware that sensorineural hearing loss may occur with pegIFN therapy.Our experience suggests that re-institution of therapy is not always associated with further hearing impairment.

    Purpose: The purpose of this study was to demonstrate that a bolus electron conformal therapy (ECT) dose plan and a mixed beam plan, composed of an intensity modulated x-ray therapy (IMXT) dose plan optimized on top of the bolus ECT plan, can be accurately delivered. Methods: Calculated dose distributions were compared with measured dose distributions for parotid and chest wall (CW) bolus ECT and mixed beam plans, each simulated in a cylindrical polystyrene phantom that allowed film dose measurements. Bolus ECT plans were created for both parotid and CW PTVs (planning target volumes) using 20 and 16 MeV beams, respectively, whose 90% dose surface conformed to the PTV. Mixed beam plans consisted of an IMXT dose plan optimized on top of the bolus ECT dose plan. The bolus ECT, IMXT, and mixed beam dose distributions were measured using radiographic films in five transverse and one sagittal planes for a total of 36 measurement conditions. Corrections for film dose response, effects of edge-on photon irradiation, and effects of irregular phantom optical properties on the Cerenkov component of the film signal resulted in high precision measurements. Data set consistency was verified by agreement of depth dose at the intersections of the sagittal plane with the five measured transverse planes. For these same depth doses, results for the mixed beam plan agreed with the sum of the individual depth doses for the bolus ECT and IMXT plans. The six mean measured planar dose distributions were compared with those calculated by the treatment planning system for all modalities. Dose agreement was assessed using the 4% dose difference and 0.2 cm distance to agreement. Results: For the combined high-dose region and low-dose region, pass rates for the parotid and CW plans were 98.7% and 96.2%, respectively, for the bolus ECT plans and 97.9% and 97.4%, respectively, for the mixed beam plans. For the high-dose gradient region, pass rates for the parotid and CW plans were 93.1% and 94

    Oncolytic viral therapy and photodynamic therapy are potential therapies for inoperable or advanced pancreatic cancer. Our aim was to investigate the anti-cancer killing effects of reovirus therapy combined with protoporphyrin IX (PpIX)-mediated photodynamic therapy on a variety of human pancreatic cancer cell lines. Pancreatic cancer cell lines (PsPC-1 and BXPC-3) and a non-cancer control cell line (HEK293) were infected with reovirus serotype 3 strain Dearing (T3D) at 0, 0·1, 1, and 10 plaque-forming units (PFU) per cell for 48 h. Cells were incubated with PpIX pro-drug 5-aminolevulinic acid (5-ALA) at 0, 1, 2, 3, and 4 mM for 4 h. Then, cells were photo-irradiated for 15 min with visible red light-emitting diodes with a light-fluence of 0·54 J/cm(2) of 653 nm (PpIX optimal excitation wavelength). The killing effects of reovirus combined with PpIX-mediated photodynamic therapy were analysed in methylthiazoltetrazolium (MTT) and trypan blue assays. The effect of adding reovirus after photodynamic therapy was also assessed. The statistical significance of the difference between groups was assessed with the two-tailed Student's t test. pphotodynamic therapy resulted in a significantly increased cytotoxic effect compared with reovirus monotherapy and photodynamic therapy (p=0·042) with 100% cell death observed across pancreatic cell lines with 10 PFU per cell combined with 1 and 2 mM 5-ALA. There was no difference in cytotoxicity observed between added reovirus before or after photodynamic therapy. To our knowledge, this is the first in-vitro study to combine reovirus oncolytic viral therapy with PpIX-mediated photodynamic therapy to treat pancreatic cancer. These results show a significant additive effect in cell killing and they provide initial evidence for a novel combined therapeutic intervention. National Institute for Health Research.

    Full Text Available Schwann cell transplantation and hyperbaric oxygen therapy each promote recovery from spinal cord injury, but it remains unclear whether their combination improves therapeutic results more than monotherapy. To investigate this, we used Schwann cell transplantation via the tail vein, hyperbaric oxygen therapy, or their combination, in rat models of spinal cord contusion injury. The combined treatment was more effective in improving hindlimb motor function than either treatment alone; injured spinal tissue showed a greater number of neurite-like structures in the injured spinal tissue, somatosensory and motor evoked potential latencies were notably shorter, and their amplitudes greater, after combination therapy than after monotherapy. These findings indicate that Schwann cell transplantation combined with hyperbaric oxygen therapy is more effective than either treatment alone in promoting the recovery of spinal cord in rats after injury.

    Objective : To evaluate clinical, Quality of Life (QoL) and medical cost outcomes in patients with symptomatic reflux esophagitis (RE) receiving different "triple combination therapy". Methods: A muhicenter medical effectiveness trial conducted in 10 hospitals of 5 regions in Zhejiang Province. 248 patient-volunteers were assigned to 8 weeks of " triple combination therapy" with Lansoprazole plus Cisapride and Sucralfate or Ranitidine plus Cisapride and Sucralfate. Main outcomes assessment included symptoms scale scores, RE severity, QoL at baseline and 8 weeks. Medical cost data were collected with cost analysis questionnaire. Resuits: (1)More Lansoprazole group patients noted RE symptoms resolution than Ranitidine group(92.3 % vs 78.4%, P 0.05) . (2)RE significantly impaired QoL of patients( P 0.05 ) . Conclusion : RE significantly impaired QoL of patients. "Triple combination therapies" can significantly improve RE symptoms and QoL. Lansoprazole combination therapy was more cost-effective than Ranitidine combination group.

    Full Text Available Artemisinin-based combination therapy-resistant malaria is rare in Sub-Saharan Africa. The World Health Organization identifies monitoring and surveillance using day-3 parasitaemia post-treatment as the standard test for identifying suspected artemisinin resistance. We report three cases of early treatment failure due to possible artemisinin-based combination therapy-resistant Plasmodium falciparum malaria. All cases showed adequate clinical and parasitological responses to quinine. This study reveals a need to re-evaluate the quality and efficacy of artemisinin-based combination therapy agents in Nigeria and Sub-Saharan Africa.

    Radiation therapy has long played a role in the management of melanoma. Recent advances have also demonstrated the efficacy of immunotherapy in the treatment of melanoma. Preclinical data suggest a biologic interaction between radiation therapy and immunotherapy. Several clinical studies corroborate these findings. This review will summarize the outcomes of studies reporting on patients with melanoma treated with a combination of radiation therapy and immunotherapy. Vaccine therapies often use irradiated melanoma cells, and may be enhanced by radiation therapy. The cytokines interferon-α and interleukin-2 have been combined with radiation therapy in several small studies, with some evidence suggesting increased toxicity and/or efficacy. Ipilimumab, a monoclonal antibody which blocks cytotoxic T-lymphocyte antigen-4, has been combined with radiation therapy in several notable case studies and series. Finally, pilot studies of adoptive cell transfer have suggested that radiation therapy may improve the efficacy of treatment. The review will demonstrate that the combination of radiation therapy and immunotherapy has been reported in several notable case studies, series and clinical trials. These clinical results suggest interaction and the need for further study.

  2. Combination antibiotic therapy for multidrug-resistant Gram-negative bacteria.

    Combination antibiotic therapy for Gram-negative sepsis is controversial. The present review provides a brief summary of the existing knowledge on combination therapy for severe infections with multidrug-resistant Pseudomonas spp., Acinetobacter spp., and Enterobacteriaceae. Empirical combination antibiotic therapy is recommended for severe sepsis and septic shock to reduce mortality related to inappropriate antibiotic treatment. Because definitive combination therapy has not been proven superior to monotherapy in meta-analyses, it is generally advised to de-escalate antibiotic therapy when the antibiotic susceptibility profile is known, although it cannot be excluded that some subgroups of patients might still benefit from continued combination therapy. Definitive combination therapy is recommended for carbapenemase-producing Enterobacteriaceae and should also be considered for severe infections with Pseudomonas and Acinetobacter spp. when beta-lactams cannot be used. Because resistance to broad-spectrum beta-lactams is increasing in Gram-negative bacteria and because no new antibiotics are expected to become available in the near future, the antibacterial potential of combination therapy should be further explored. In vitro data suggest that combinations can be effective even if the bacteria are resistant to the individual antibiotics, although existing evidence is insufficient to support the choice of combinations and explain the synergistic effects observed. In vitro models can be used to screen for effective combinations that can later be validated in animal or clinical studies. Further, in the absence of clinical evidence, in vitro data might be useful in supporting therapeutic decisions for severe infections with multidrug-resistant Gram-negative bacteria.

    Robot-assisted therapy (RT) and constraint-induced therapy (CIT) both show great promise to improve stroke rehabilitation outcomes. Although the respective treatment efficacy of RT and CIT has been validated, the additive effects of RT combined with CIT remain unknown. This study investigated the treatment effects of RT in sequential combination with a distributed form of CIT (RT + dCIT) compared with RT and conventional rehabilitation (CR). Forty-eight patients with stroke were enrolled and randomized to receive one of the three interventions for 4 weeks. Primary outcomes assessed the changes of motor impairment and motor function on the Fugl-Meyer Assessment (FMA) and Wolf Motor Function Test (WMFT). Secondary outcomes, including the Motor Activity Log (MAL) and accelerometers, examined functional performance during daily activities. The three treatment groups improved significantly on most primary and secondary outcomes over time. The combined RT + dCIT group exhibited significantly greater improvement on the FMA and functional ability subscale of the WMFT than the RT and CR groups. The improvements on the MAL and accelerometers were not significantly different among the three groups. RT in sequential combination with CIT led to additive effects on participants' motor ability and functional ability to perform motor tasks after stroke, which support that combined therapy can be an effective means to intensify outcomes. Further research investigating the potential long-term effects of combination therapy, especially on real-life performance, would be valuable.

    Full Text Available Alberto F Rubio-Guerra1, David Castro-Serna2, Cesar I Elizalde Barrera2, Luz M Ramos-Brizuela21Metabolic and Research Clinic, 2Internal Medicine Department, Hospital General de Ticomán SS DF, MéxicoAbstract: Recent guidelines for the management of hypertension recommend target blood pressures <140/90 mmHg in hypertensive patients, or <130/80 mmHg in subjects with diabetes, chronic kidney disease, or coronary artery disease. Despite the availability and efficacy of antihypertensive drugs, most hypertensive patients do not reach the recommended treatment targets with monotherapy, making combination therapy necessary to achieve the therapeutic goal. Combination therapy with 2 or more agents is the most effective method for achieving strict blood pressure goals. Fixed-dose combination simplifies treatment, reduces costs, and improves adherence. There are many drug choices for combination therapy, but few data are available about the efficacy and safety of some specific combinations. Combination therapy of calcium antagonists and inhibitors of the renin-angiotensin-aldosterone system (RAAS are efficacious and safe, and have been considered rational by both the JNC 7 and the 2007 European Society of Hypertension – European Society of Cardiology guidelines for the management of arterial hypertension. The aim of this review is to discuss some relevant issues about the use of combinations with calcium channel blockers and RAAS inhibitors in the treatment of hypertension.Keywords: hypertension, calcium channel blockers, renin-angiotensin-aldosterone system inhibitors, fixed-dose combination, adherence

    Objective This study investigated the role of a specialized physical therapy program for muscle tension dysphonia patients as an adjunct to standard of care voice therapy. Study Design Retrospective Cohort Study Methods Adult MTD patients seen between 2007 and 2012 were identified from the clinical database. They were prescribed voice therapy and, if concomitant neck pain, adjunctive physical therapy. In a pragmatic observational cohort design, patients underwent one of four potential treatment approaches: voice therapy alone (VT), voice therapy and physical therapy (VT+PT), physical therapy alone (PT), or incomplete/no treatment. Voice handicap outcomes were compared between treatment approaches. Results Of 153 patients meeting criteria (Median age 48 years, 68% female, and 30% had fibromyalgia, chronic pain, chronic fatigue, depression, and/or anxiety), there was a similar distribution of patients with moderate or severe pre-treatment VHI scores across treatment groups (VT 45.5%, VT+PT 43.8%, PT 50%, no treatment 59.1%; p=0.45). Patients treated with VT alone had significantly greater median improvement in VHI than those not treated: 10-point vs. 2-point (p=0.02). Interestingly, median VHI improvement in patients with baseline moderate-severe VHI scores was no different between VT (10), VT+PT (8) and PT alone (10; p=0.99). Conclusions Findings show voice therapy to be an effective approach to treating MTD. Importantly, other treatment modalities incorporating physical therapy had a similar, albeit not significant, improvement in VHI. This preliminary study suggests that physical therapy techniques may have a role in the treatment of a subset of MTD patients. Larger, comparative studies are needed to better characterize the role of physical therapy in this population. PMID:26012419

    The prognosis of recurrent medulloblastoma is dismal, with a median survival of less than 1 year. Our patient was initially diagnosed with high-risk medulloblastoma when he was 14 years old. He had a recurrence 18 months after the end of therapy. Recurrence treatment consisted of 13 intrathecal applications of liposomal cytarabine over an 18-month period, and oral metronomic antiangiogenic therapy with thalidomide, celecoxib, and etoposide. Side effects from the intrathecal treatment were most likely related to arachnoiditis despite prolonged prophylaxis with steroids. He also developed partial hearing loss. Neutropenia was the main side effect of the metronomic therapy. He remains alive, with a good quality of life and without evidence of disease 34 months from the start of recurrence therapy. This combination of local antineoplastic and systemic antiangiogenic therapy seems to be promising for recurrent medulloblastoma. However, more patients and standardized protocols are needed to verify the benefit of this combination therapy and to define the correct duration of treatment.

    Liposomal amphotericin B (LAmB) combined wither either micafungin or deferasirox was synergistic in previous murine studies with mucormycosis or aspergillosis. We hypothesized that triple therapy using LAmB, micafungin, and deferasirox could further improve outcomes of mucormycosis or aspergillosis. Triple therapy improved survival and reduced tissue fungal burden of mice with mucormycosis and to a lesser extent with aspergillosis. Continued investigation into the use of triple therapy against mucormycosis and aspergillosis is warranted.

    Full Text Available The paper gives data on the use of a combination of genetic engineering biological agents (GEBAs and leflunomide in patients with rheumatoid arthritis (RA. In accordance with the international guidelines, the majority of GEBAs should be given in a combination with methotrexate (MTX, which increases the efficacy of a number of GEBAs (tumor necrosis factor-α inhibitors, rituximab and affects tolerability (remikeid, humira. However, MTX cannot be always used in real practice. The data given in the paper on the efficiency and safety of the coadministration of leflunomide and a GEBA in patients with active RA, which are based on the results of randomized studies and national registers, including the Russian one, point to the compatibility of the results of treatment with this and GEBA-MTX combinations.

    Combining controllable photothermal therapy and efficacious gene therapy in a single platform holds great promise in cancer therapy due to the enhanced combined therapeutic effects. Herein, polyethyleneimine-grafted oxidized mesoporous carbon nanospheres (OP) were developed for combined photothermal combined gene therapy in vitro and in vivo. The synthesized OP was characterized to have three dimensional spherical structure with uniformed diameter, ordered mesopores with graphitic domains, high water dispersion with zeta potential of +22 mV, and good biocompatibility. Consequently, OP was exploited as the photothermal convertor with strong NIR absorption and the gene vector via electrostatic interaction, which therefore cannot only deliver the therapeutic gene (pING4) to tumors for gene therapy, but also can eliminate the tumors by photothermal ablation. Moreover, the improved gene therapy accompanied by the NIR photothermally enhanced gene release was also well achieved based on OP. The excellent combined therapeutic effects demonstrated in vitro and in vivo suggested the OP's potential for cancer therapy.

    Disinfectant and antibacterial properties of ozone are utilized in the treatment of nonhealing or ischemic wounds. We present here a case of 59 years old woman with compartment syndrome following surgical treatment of stress fracture of proximal tibia with extensively infected wound and exposed tibia to about 4/5 of its extent. The knee joint was also infected with active pus draining from a medial wound. At presentation the patient had already taken treatment for 15 days in the form of repeated wound debridements and parenteral antibiotics, which failed to heal the wound and she was advised amputation. Topical ozone therapy twice daily and ozone autohemotherapy once daily were given to the patient along with daily dressings and parenteral antibiotics. Within 5 days, the wound was healthy enough for spilt thickness skin graft to provide biological dressing to the exposed tibia bone. Topical ozone therapy was continued for further 5 days till the knee wound healed. On the 15(th) day, implant removal, intramedullary nailing, and latissimus dorsi pedicle flap were performed. Both the bone and the soft tissue healed without further complications and at 20 months follow-up, the patient was walking independently with minimal disability.

    The advances in radiotherapy (3D-CRT, IMRT) have enabled high doses of radiation to be delivered with the least possible associated toxicity. However, the persistence of cancer (local recurrence after radiotherapy) despite these increased doses as well as distant failure suggesting the existence of micro-metastases, especially in the case of higher risk disease, have underscored the need for continued improvement in treatment strategies to manage local and micro-metastatic disease as definitively as possible. This has prompted the idea that an increase in the therapeutic index of radiotherapy might be achieved by combining it with in situ gene therapy. The goal of these combinatorial therapies is to maximize the selective pressure against cancer cell growth while minimizing treatment-associated toxicity. Major efforts utilizing different gene therapy strategies have been employed in conjunction with radiotherapy. We reviewed our and other published clinical trials utilizing this combined radio-genetherapy approach including their associated pre-clinical in vitro and in vivo models. The use of in situ gene therapy as an adjuvant to radiation therapy dramatically reduced cell viability in vitro and tumor growth in vivo. No significant worsening of the toxicities normally observed in single-modality approaches were identified in Phase I/II clinical studies. Enhancement of both local and systemic T-cell activation was noted with this combined approach suggesting anti-tumor immunity. Early clinical outcome including biochemical and biopsy data was very promising. These results demonstrate the increased therapeutic efficacy achieved by combining in situ gene therapy with radiotherapy in the management of local prostate cancer. The combined approach maximizes tumor control, both local-regional and systemic through radio-genetherapy induced cytotoxicity and anti-tumor immunity.

    Full Text Available Purpose: To study the various changes in the course of cytomegalovirus (CMV retinitis following combination antiretroviral treatment. Methods: Combination antiretroviral treatment was given to 12 patients with active CMV retinitis following which all anti-CMV medications were discontinued once the CD4 cell counts were> 100/mm3 for 3 months. Results: The median CD4 cell count increased from 36.5/mm3 (range, 3-74/mm3 at baseline to 175.5/mm3 (range, 97-410/mm3 at 3 months. No patient had reactivation of CMV retinitis or developed extraocular CMV infection during median follow-up of 16.7 months. In one patient with peripheral active CMV retinitis, the retinitis resolved completely and remained so throughout the follow-up period without specific anti-CMV treatment. Five (41.7% patients had immune recovery vitritis. Conclusion: Patients receiving combination antiretroviral treatment following treatment for CMV retinitis have better control of CMV retinitis but immune recovery vitritis is a common sequelae. Reactivation of CMV retinitis is common in patients who discontinue combination antiretroviral treatment

    Chronic prostatitis is characterized by clinical polymorphism, that may include pain, dysuria, asthenovegetative syndrome, and others. Symptoms associated with impaired copulatory cycle in chronic prostatitis have a significant impact on the quality of life of patient. Sexual dysfunction and sexuality cessation can exacerbate the inflammation of the prostate gland and worsen the underlying disease. The study included 60 patients diagnosed with chronic bacterial prostatitis, complicated by sexual disorders. Patients were divided into two comparable groups of 30 persons. Control group ofpatients received standard antibacterial therapy; study group ofpatients in addition received phytodrug prostanorm. At the end of treatment, higher IIEF-5 scores, increasing number of lecithin granules in the prostate secretion, as well as reducing the severity of irritative symptoms were registered in the study group.

  6. Healing the wounded self: combining hypnotherapy with ego state therapy.

    The purpose of this article is to formulate a theoretical conceptualization for utilizing ego state therapy (EST) as an adjunct with cognitive hypnotherapy (CH) for depression. As the relationship between life events and onset of depression is very complex, it is not clear from current literature how stressors cause depressive symptoms. The notion of "wounded self," derived from the work of Wolfe (2005, 2006), is examined as a potential unifying concept for binding the role of risk factors in the precipitation of depression. By incorporating wounded self, the circular feedback model of depression, on which CH for depression is based, is expanded. This revised version provides conceptual and empirical underpinnings for integrating EST with CH in the management of depression.

    In healthy individuals, immune-checkpoint molecules prevent autoimmune responses and limit immune cell-mediated tissue damage. Tumors frequently exploit these molecules to evade eradication by the immune system. Over the past years, immune-checkpoint blockade of cytotoxic T lymphocyte antigen-4 and programed death-1 emerged as promising strategies to activate antitumor cytotoxic T cell responses. Although complete regression and long-term survival is achieved in some patients, not all patients respond. This review describes promising, novel combination approaches involving immune-checkpoint blockade in the context of the cancer-immunity cycle, aimed at increasing response rates to the single treatments. Specifically, we discuss combinations that promote antigen release and presentation, that further amplify T cell activation, that inhibit trafficking of regulatory T cells or MSDCs, that stimulate intratumoral T cell infiltration, that increase cancer recognition by T cells, and that stimulate tumor killing.

    Twelve cases of carcinoma of the rectum were treated preoperatively by combination therapy with 5-fluorouracil (5-FU) suppository (100 mg twice a day consecutively, a total dose of more than 4,000 mg) and irradiation (300 rad x 3/week, a total dose of 3,000 rad). This group was compared with 34 cases given single preoperative 5-FU therapy and 24 control cases given no preoperative adjuvant modality. The group treated by preoperative combination therapy showed marked antitumor effects macroscopically and histologically. In addition, decrease in local recurrence was expected for this group, compared with the other two groups.

    This study investigates the effect of combining both mirror therapy with Electrical Stimulation (ES) on improvement of the function of lower extremity compared to conventional therapy. 18 stroke survivors (sub acute stage) were recruited, 9 of them were randomly assigned to receive conventional treatment and another 9 started the mirror therapy combined with ES treatment. Duration of each session in both interventions was 50 minutes, done 4 times per week over two weeks. After 2 weeks, subjects took one week rest before switching they type of treatment; those started with conventional therapy continued with mirror therapy combined with ES, and vice versa. The duration of this phase was 2 weeks with same schedule as the 1st one. Ankle dorsi-flexion range of motion, lower extremity sensory-motor function, and walking duration were measured at baseline, after 1st 2 weeks, and immediately after the last two weeks, and 4 weeks after end of training (retention test). Repeated Measures ANCOVA was done to compare outcome measures scores in both groups and between all testing days, and paired T-test was used measure the difference between groups. Significant increase in all outcome measures was found after the (MT+ES) training, which is higher than conventional therapy training (pmirror therapy and ES is more effective than conventional therapy in improving lower limb motor function after stroke.

    Brain stroke is the second most important events that lead to disability and morbidity these days. Although, stroke is important, there is no treatment for curing this problem. Nowadays, cell therapy has opened a new window for treating central nervous system disease. In some previous studies the Mesenchymal stem cells and neural stem cells. In this study, we have designed an experiment to assess the combination cell therapy (Mesenchymal and Neural stem cells) effects on brain stroke. The Mesenchymal stem cells were isolated from adult rat bone marrow and the neural stem cells were isolated from ganglion eminence of rat embryo 14 days. The Mesenchymal stem cells were injected 1 day after middle cerebral artery occlusion (MCAO) and the neural stem cells transplanted 7 day after MCAO. After 28 days, the neurological outcomes and brain lesion volumes were evaluated. Also, the activity of Caspase 3 was assessed in different groups. The group which received combination cell therapy had better neurological examination and less brain lesion. Also the combination cell therapy group had the least Caspase 3 activity among the groups. The combination cell therapy is more effective than Mesenchymal stem cell therapy and neural stem cell therapy separately in treating the brain stroke in rats.

    Summary: This paper explores historical and current roles of pharmaceutical industry sponsorship of clinical trials testing radiation therapy combinations with molecularly targeted agents and attempts to identify potential solutions to expediting further combination studies. An analysis of clinical trials involving a combination of radiation therapy and novel cancer therapies was performed. Ongoing and completed trials were identified by searching the (clinicaltrials.gov) Web site, in the first instance, with published trials of drugs of interest identified through American Society of Clinical Oncology, European CanCer Organisation/European Society for Medical Oncology, American Society for Radiation Oncology/European Society for Therapeutic Radiology and Oncology, and PubMed databases and then cross-correlated with (clinicaltrials.gov) protocols. We examined combination trials involving radiation therapy with novel agents and determined their distribution by tumor type, predominant molecular mechanisms examined in combination to date, timing of initiation of trials relative to a novel agent's primary development, and source of sponsorship of such trials. A total of 564 studies of targeted agents in combination with radiation therapy were identified with or without concomitant chemotherapy. Most studies were in phase I/II development, with only 36 trials in phase III. The tumor site most frequently studied was head and neck (26%), followed by non-small cell lung cancer. Pharmaceutical companies were the sponsors of 33% of studies overall and provided support for only 16% of phase III studies. In terms of pharmaceutical sponsorship, Genentech was the most active sponsor of radiation therapy combinations (22%), followed by AstraZeneca (14%). Most radiation therapy combination trials do not appear to be initiated until after drug approval. In phase III studies, the most common (58%) primary endpoint was overall survival. Collectively, this analysis suggests that

    Full Text Available Oral candidiasis is one of the most common opportunistic infections in HIV/AIDS patients. It serves as important markers of HIV infection, viral load, and CD4 cells count in the blood and predict disease progression to AIDS. The development of oral candidiasis in HIV/AIDS patients associated by imbalances between Candida and impaired host immune defenses that caused by decreased of CD4 cell counts and the increased of plasma HIV-viral load. Since the introduction of antiretroviral therapy combination, commonly known as Highly Active Antiretroviral Therapy (HAART, it has been observed that certain oral lesions, such as oral candidiasis as declined. The aim of this paper is to review the mechanism of combination antiretroviral therapy influenced the frequency of oral candidiasis in HIV/AIDS patient. We conclude that combination antiretroviral therapy generally reduced the frequency and severity of oral candidiasis in HIV/AIDS patient.

    The benefits of β-lactam/macrolide combination therapy over β-lactam therapy alone for the treatment of hospitalised community-acquired pneumonia (CAP) in relation to pneumonia severity are uncertain. We studied 5240 adults hospitalised with CAP from 72 secondary care trusts across England and Wales. The overall 30-day inpatient (IP) death rate was 24.4%. Combination therapy was prescribed in 3239 (61.8%) patients. In a multivariable model, combination therapy was significantly associated with lower 30-day IP death rate in patients with moderate-severity CAP (adjusted OR 0.54, 95% CI 0.41 to 0.72) and high-severity CAP (adjusted OR 0.76, 95% CI 0.60 to 0.96) but not low-severity CAP.

    Full Text Available Background Trichuris trichiura is one of the most common soil-transmitted helminths, estimated to infect 1 billion people worldwide. Several studies have compared the efficacies of albendazole and diethylcarbamazine, but the efficacy of a combination of these two drugs has been inconclusive. Objective To assess the effectiveness of a single dose of albendazole compared to a combination of albendazole and diethylcarbamazine for trichuriasis treatment. Methods A randomized, clinical open trial was conducted from June to September 2009 on elementary school children with trichuriasis from two villages in the North Sumatera Province. Stool specimens were collected at baseline and at days 7, 14, 21, and 28 after treatment, and examined by the Kato Katz method. Subjects were randomized into two groups. Group I received a single dose of albendazole (400 mg and group II received albendazole (400 mg plus diethylcarbamazine (6 mg/kg. Statistical analyses used were Chi square test for cure rates and Wilcoxon rank test for egg reduction rates. Results One hundred eight children were enrolled and randomized into group 1 (53 children and group II (55 children. The prevalence of T. trichiura infection was 54.7%. There were no significant differences (P=0.52 in the cure rate between groups I and II (66% and 60%, respectively or in egg reduction rates at day 28 (54.5% and 60.07%, respectively, P= 0.10. Conclusion Albendazole alone and abendazole combined with diethylcarbamazine have similar efficacies for trichuriasis treatment, in terms of cure rates and egg reduction rates.

  17. Use of biologic agents in combination with other therapies for the treatment of psoriasis.

    2014-12-01

    Psoriasis is a chronic inflammatory skin disorder, which is associated with a significant negative impact on a patient's quality of life. Traditional therapies for psoriasis are often not able to meet desired treatment goals, and high-dose and/or long-term use is associated with toxicities that can result in end-organ damage. An improved understanding of the involvement of cytokines in the etiology of psoriasis has led to the development of biologic agents targeting tumor necrosis factor (TNF)-α and interleukins (ILs)-12/23. While biologic agents have improved treatment outcomes, they are not effective in all individuals with psoriasis. The combination of biologic agents with traditional therapies may provide improved therapeutic options for patients who inadequately respond to a single drug or when efficacy may be increased with supplementation of another treatment. In addition, combination therapy may reduce safety concerns and cumulative toxicity, as lower doses of individual agents may be efficacious when used together. This article reviews the current evidence available on the efficacy and safety of combining biologic agents with systemic therapies (methotrexate, cyclosporine, or retinoids) or with phototherapy, and the combination of biologic agents themselves. Guidance is provided to help physicians identify situations and the characteristics of patients who would benefit from combination therapy with a biologic agent. Finally, the potential clinical impact of biologic therapies in development (e.g., those targeting IL-17A, IL-17RA, or IL-23 alone) is analyzed.

    Full Text Available Ian Hamilton-Craig1, Karam Kostner2, David Colquhoun2, Stan Woodhouse21Griffith University School of Medicine, Southport, Queensland, Australia; 2University of Queensland, Brisbane, Queensland, AustraliaAbstract: High-dose potent statin therapy in combination with ezetimibe is now standard practice for the treatment of adult patients with heterozygous familial hypercholesterolemia (heFH, as the result of numerous studies in patients with primary hypercholesterolemia or heFH. These studies have shown the combination to be both effective and safe in the short to medium term. Recently, short-term ezetimibe therapy has also been shown to be effective and safe in combination with statin therapy for children and adolescents with heFH. Effective statin–ezetimibe combination therapy is capable of achieving near-normal lipid profiles in heFH patients, with expected improvement in risk for cardiovascular disease (CVD and improved life expectancy resulting predominantly from reduction in levels of low-density lipoprotein cholesterol. There are few data to support a pleiotropic action of ezetimibe with regard to CVD benefit, unlike therapy with statins. No serious and unexpected clinical adverse effects of combination statin–ezetimibe therapy have emerged till date, although data are limited in children and adolescents, for whom longer-term studies are required. Recent data suggesting possible proatherogenic effects of ezetimibe require confirmation. One large long-term randomized controlled clinical outcomes trial is in progress in non-FH patients to determine the efficacy and safety of ezetimibe therapy; it is unlikely that such a trial will ever be performed in patients with FH.Keywords: familial hypercholesterolemia, ezetimibe, statin, combination therapy, low-density lipoprotein cholesterol

    The aim of the study was to analyze the clinical use of different types of combination therapy in a large sample of consecutive patients with uncontrolled hypertension referred to Hypertension Centre. We performed a retrospective analysis of combination antihypertensive therapy in 1254 consecutive patients with uncontrolled hypertension receiving at least triple-combination antihypertensive therapy. Among the most prescribed antihypertensive classes were renin-angiotensin blockers (96.8%), calcium channel blockers (82.5%), diuretics (82.0%), beta-blockers (73.0%), centrally acting drugs (56.0%) and urapidil (24.1%). Least prescribed were spironolactone (22.2%) and alpha-1-blockers (17.1%). Thiazide/thiazide-like diuretics were underdosed in more than two-thirds of patients. Furosemide was prescribed in 14.3% of patients treated with diuretics, while only indicated in 3.9%. Inappropriate combination therapy was found in 40.4% of patients. Controversial dual and higher blockade of renin-angiotensin system occurred in 25.2%. Incorrect use of a combination of two antihypertensive drugs with the similar mechanism of action was found in 28.1%, most commonly a combination of two drugs with central mechanism (13.5%). In conclusion, use of controversial or incorrect combinations of drugs in uncontrolled hypertension is common. Diuretics are frequently underdosed and spironolactone remains neglected in general practice. The improper combination of antihypertensive drugs may contribute to uncontrolled hypertension.

    Acinetobacter baumannii is a drug-resistant Gram-negative pathogen increasingly causing hospital-acquired infections in critically ill patients. In this review, we summarize the current mechanisms of antimicrobial resistance in A. baumannii and describe in detail recent in vitro and in vivo experimental data on the activity of antimicrobial combinations against this microorganism. We then introduce the rationale for the use of combination antibiotic therapy in resistant A. baumannii infections. Finally, we present and critically discuss both uncontrolled clinical studies and the few randomized clinical trials of combination antimicrobial therapy for these infections, with a special focus on ongoing multinational trials and optimal approach to future research in this field.

    Full Text Available Abstract Recent publications put a serious warning regarding the inefficacy of sulphadoxine-pyrimethamine (SP for the intermittent preventive treatment of malaria in young children (IPTi. Recommendations for other therapies are being made. By using a different and better sulphonamide (sulphamethoxypyrazine, it is possible to manufacture fixed dose combination pills with artesunate and pyrimethamine. This combination permits a full therapy over 24 hours (dosing interval being 12 hours. It is recommended that this combination should be tested in future field studies of IPTi.

    The standard of care for transitional-cell carcinoma of the bladder with invasion to the muscularis propria is radical cystectomy. Sophisticated techniques for urinary diversion have been developed to improve patients' quality of life. Even the construction of a neobladder with continent urinary diversion, however, cannot substitute for the patient's original bladder. Attempts to obtain organ preservation are only justified when they have a high likelihood of achieving local cure with no compromise in survival rates. Adequate local control cannot be achieved with transurethral resection of the bladder tumor (TURBT), chemotherapy, or radiotherapy, when used alone. Several groups have reported the value of combining all three modalities, with salvage cystectomy being reserved for patients with incomplete response or local relapse. (orig.)

    Testing the new combined bronchodilator Anoro Ellipta in different clinical trials gives to its high clinical efficacy and safety in chronic obstructive pulmonary disease. The drug contains the molecules of sustained-release selective β2-adrenergic receptor agonist (vilanterol) and a muscarinic cholinergic receptor antagonist (umeclidinium bromide). The bronchodilating mechanisms of umeclidinium bromide are in the competitive inhibition of the binding of acetylcholine with muscarinic acetylcholine receptors of airway smooth muscles whereas in those of vilanterol are in that with the stimulation of intracellular adenylate cyclase. On days 1 and 24 after inhalation of the first dose of vilanterol and umeclidinium bromide, there was a significant increase in the forced expiratory volume in one second as compared to placebo. No clinical effects on QT interval on an electrocardiogram and cardiac rhythm were found. The benefits of an inhalation device (Ellipta) are its innovation design ensuring the effective delivery of an aerosol dose into the airway, convenience, and simplicity.

    Chronic disease caused by infections, cancer or autoimmunity can result in profound immune suppression. Immunoregulatory networks are established to prevent tissue damage caused by inflammation. Although these immune checkpoints preserve tissue function, they allow pathogens and tumors to persist, and even expand. Immune checkpoint blockade has recently been successfully employed to treat cancer. This strategy modulates immunoregulatory mechanisms to allow host immune cells to kill or control tumors. However, the utility of this approach for controlling established infections has not been extensively investigated. Here, we examined the potential of modulating glucocorticoid-induced TNF receptor-related protein (GITR) on T cells to improve anti-parasitic immunity in blood and spleen tissue from visceral leishmaniasis (VL) patients infected with Leishmania donovani. We found little effect on parasite growth or parasite-specific IFNγ production. However, this treatment reversed the improved anti-parasitic immunity achieved by IL-10 signaling blockade. Further investigations using an experimental VL model caused by infection of C57BL/6 mice with L. donovani revealed that this negative effect was prominent in the liver, dependent on parasite burden and associated with an accumulation of Th1 cells expressing high levels of KLRG-1. Nevertheless, combined anti-IL-10 and anti-GITR mAb treatment could improve anti-parasitic immunity when used with sub-optimal doses of anti-parasitic drug. However, additional studies with VL patient samples indicated that targeting GITR had no overall benefit over IL-10 signaling blockade alone at improving anti-parasitic immune responses, even with drug treatment cover. These findings identify several important factors that influence the effectiveness of immune modulation, including parasite burden, target tissue and the use of anti-parasitic drug. Critically, these results also highlight potential negative effects of combining different

  8. Epigenetic polypharmacology: from combination therapy to multitargeted drugs.

    de Lera, Angel R; Ganesan, A

    The modern drug discovery process has largely focused its attention in the so-called magic bullets, single chemical entities that exhibit high selectivity and potency for a particular target. This approach was based on the assumption that the deregulation of a protein was causally linked to a disease state, and the pharmacological intervention through inhibition of the deregulated target was able to restore normal cell function. However, the use of cocktails or multicomponent drugs to address several targets simultaneously is also popular to treat multifactorial diseases such as cancer and neurological disorders. We review the state of the art with such combinations that have an epigenetic target as one of their mechanisms of action. Epigenetic drug discovery is a rapidly advancing field, and drugs targeting epigenetic enzymes are in the clinic for the treatment of hematological cancers. Approved and experimental epigenetic drugs are undergoing clinical trials in combination with other therapeutic agents via fused or linked pharmacophores in order to benefit from synergistic effects of polypharmacology. In addition, ligands are being discovered which, as single chemical entities, are able to modulate multiple epigenetic targets simultaneously (multitarget epigenetic drugs). These multiple ligands should in principle have a lower risk of drug-drug interactions and drug resistance compared to cocktails or multicomponent drugs. This new generation may rival the so-called magic bullets in the treatment of diseases that arise as a consequence of the deregulation of multiple signaling pathways provided the challenge of optimization of the activities shown by the pharmacophores with the different targets is addressed.

    To describe new users of antihypertensive medications and identify predictors of combination therapy initiation in older Americans. Retrospective observational cohort study. Population-based study using U.S. Medicare fee-for-service healthcare claims (2007-2010). Medicare beneficiaries aged 65 and older with no recent diagnoses, procedures, or medications for cardiovascular disease who newly initiated an antihypertensive therapy (n = 275,493; 210,605 initiated monotherapy, 64,888 initiated combination therapy). Multivariable Poisson regression was used to assess factors associated with initiation of combination therapy versus monotherapy, including participant characteristics, prescriber characteristics, and participant encounters with the healthcare system. Initiation of combination therapy increased from 21.9% in 2007 to 24.7% in 2010. The most frequently initiated combinations were angiotensin-converting enzyme inhibitors with thiazide (29.7%) and angiotensin II receptor antagonists with thiazide (18.7%). Blacks (prevalence ratio (PR) = 1.48, 95% confidence interval (CI) = 1.45-1.51 vs. whites), individuals seeing a generalist (PR = 1.10, 95% CI = 1.07-1.14), individuals seeing more than one doctor (PR = 3.38, 95% CI = 3.33-3.44), and participants with no pharmacy claims in the previous 6 months (PR = 1.34, 95% CI = 1.30-1.37 vs. ≥3 unique drug classes) were more likely to initiate combination therapy, whereas those who had more outpatient visits in the previous 12 months were less likely to initiate combination therapy (per five visits, PR = 0.82, 95% CI = 0.80-0.83). Nearly one in four new users of antihypertensive medications aged 65 and older started treatment with combination therapy. Blacks, individuals living in the south, and those with fewer outpatient physician office visits were more likely to initiate combination therapy. Further research is needed to determine whether this approach to managing hypertension is being well targeted to individuals who

    Full Text Available Periodic assessment of gene expression for diagnosis and monitoring in rheumatoid arthritis (RA may provide a readily available and useful method to detect subclinical disease progression and follow responses to therapy with disease modifying anti-rheumatic agents (DMARDs or anti-TNF-α therapy. We used quantitative real-time PCR to compare peripheral blood gene expression profiles in active ("unstable" RA patients on DMARDs, stable RA patients on DMARDs, and stable RA patients treated with a combination of a DMARD and an anti-TNF-α agent (infliximab or etanercept to healthy human controls. The expression of 48 inflammatory genes were compared between healthy controls (N=122, unstable DMARD patients (N=18, stable DMARD patients (N=26, and stable patients on combination therapy (N=20. Expression of 13 genes was very low or undetectable in all study groups. Compared to healthy controls, patients with unstable RA on DMARDs exhibited increased expression of 25 genes, stable DMARD patients exhibited increased expression of 14 genes and decreased expression of five genes, and combined therapy patients exhibited increased expression of six genes and decreased expression of 10 genes. These findings demonstrate that active RA is associated with increased expression of circulating inflammatory markers whereas increases in inflammatory gene expression are diminished in patients with stable disease on either DMARD or anti-TNF-α therapy. Furthermore, combination DMARD and anti-TNF-α therapy is associated with greater reductions in circulating inflammatory gene expression compared to DMARD therapy alone. These results suggest that assessment of peripheral blood gene expression may prove useful to monitor disease progression and response to therapy.

    The therapeutic effects of intensive insulin therapy in treatment of traumatic shock combined with multiple organ dysfunction syndrome (MODS) were investigated. A total of 114 patients with traumatic shock combined with MODS were randomly divided into two groups: control group (n=56) treated with conventional therapy, and intensive insulin therapy group (n=58) treated with conventional therapy plus continuous insulin pumping to control the blood glucose level at range of 4.4-6.1 mmol/L. White blood cells (WBC) counts, prothrombin time (PT), serum creatinine (SCr), alanine aminotransferase (ALT), serum albumin and PaO(2) were measured before and at the day 1, 3, 5, 7 and 14 after treatment. The incidence of gastrointestinal dysfunction, the incidence of MODS, hospital stay and the mortality were also observed and compared. After intensive insulin therapy, the WBC counts, SCr, ALT and PT were significantly reduced (Pinsulin therapy. The incidence of gastrointestinal dysfunction, the incidence of MODS, the length of hospital stay and the mortality were markedly decreased (Pinsulin therapy is effective for traumatic shock combined with MODS and can decrease the length of hospital stay and the mortality.

    Patients with cerebral malaria (CM) are unable to take oral medication due to impaired consciousness and vomiting thus necessitating parenteral therapy. Quinine, artemether, and artesunate which are currently used for parenteral malaria therapy have their own drawbacks. The World Health Organization (WHO) has now banned monotherapy and recommends artemisinin-based combination therapy for malaria treatment. However, presently there is no intravenous formulation available for combination therapy of malaria. Artemether-Lumefantrine (ARM-LFN) is a WHO approved combination for oral malaria therapy. However, the low aqueous solubility of ARM and LFN hinders their intravenous delivery. The objective of this study was to formulate ARM-LFN nanostructured lipid carriers (NLC) for intravenous therapy of CM. ARM-LFN NLC were prepared by microemulsion template technique and characterized for size, drug content, entrapment efficiency, drug release, crystallinity, morphology, amenability to autoclaving, compatibility with infusion fluids, stability, antimalarial efficacy in mice, and toxicity in rats. The ARM-LFN NLC showed sustained drug release, amenability to autoclaving, compatibility with infusion fluids, good stability, complete parasite clearance and reversal of CM symptoms with 100% survival in Plasmodium berghei-infected mice, and safety in rats. The biocompatible ARM-LFN NLC fabricated by an industrially feasible technique offer a promising solution for intravenous therapy of CM. Copyright © 2016 Elsevier B.V. All rights reserved.

    Clinical studies have shown that the combination of an inhaled corticosteroid (ICS) and a long-acting beta2-adrenoceptor agonist (LABA) for patients with asthma is more effective than the use of ICS alone in equivalent or higher doses, as well as the use of other combinations. However, the relatively higher acquisition costs for the combination therapy require assessment of the value of the incremental costs, especially from a societal perspective.

    A 68-year-old man underwent subtotal esophagectomy with two fields lymphadenectomy and postoperative chemotherapy so called low dose FP therapy for advanced esophageal cancer (Stage IIIa, pT 3, pN 1, M 0) in October 1999. As he was diagnosed with a recurrence of esophageal cancer as metastatic lymph node tumors which were placed in the right anterocervical and supraclavicular region in March 2001, he underwent enucleation of metastatic lymph node tumors and postoperative chemoradiation therapy, so-called low-dose FP-R therapy. Recently, since other metastatic lymph node tumors in the neck appeared again in August 2001, he underwent radical neck lymph node dissection and postoperative chemoradiation treatment, so-called FAP-R therapy. In October 2003, a chest CT showed multiple lung tumors. He was diagnosed with multiple metastatic lung tumors originating from esophageal cancer. Then, two courses of a combined chemotherapy consisting of TS-1 and CDDP were administered at an interval of one month. We judged the effect of this chemotherapy to be a partial response (PR), because the largest metastatic lung tumor 18 mm in diameter showed a reduction rate of 81.9%, and other tumors had almost disappeared in the chest CT after the combined therapy. No severe adverse effects of more than grade 3 were observed during this combined therapy. This combined chemotherapy consisting of TS-1 and CDDP may prove effective for treating recurrent cases of esophageal cancer.

    Full Text Available Background Although the incidence of diarrhea in Indonesia has declined in the last five years, the mortality rate in children under five years old is still high. Therefore, appropriate and comprehensive management of diarrhea is essential. There have been many studies on the role of zinc therapy and probiotic therapy in reducing the severity of acute diarrhea, but not many studies have compared the use of a combination of the two therapies to zinc therapy alone. Objective To compare the efficacy of zinc-probiotic combination therapy to zinc alone in reducing the severity of acute diarrhea. Methods We conducted a randomized, open-label, controlled trial from July 2009 to January 2010 in Adam Malik Hospital and Pirngadi Hospital, Medan. Children aged between 1 month and 5 years who met the criteria were divided into two groups. Group I received zinc sulphate (aged <6 months: 10 mg/day; aged 2:6 months: 20 mg/day combined with heat-killed Lactobacillus acidophilus (3x101O CFU/day for 10 days. Group II received only zinc sulphate at the same dosage as group I. Measurement of disease severity was based on the frequency of diarrhea (times/day and the duration of diarrhea (hours after initial drug consumption. Results Eighty subjects were enrolled, randomised, and divided equally into two groups. 40 children received zinc-probiotic in combination (group I and the remainder (group II received zinc alone. We observed significant differences in frequency of diarrhea (2.1 vs 3.1 times/day, P=0.001, 95%CI -1.62 to -0.49, and duration of diarrhea (52.1 vs. 72.6 hours, P=0.00l, 95%CI -30.91 to -10.18 in the two groups. Conclusion Combination of zinc-probiotic therapy was more effective in reducing the severity of acute diarrhea than zinc therapy alone in children under five years of age.

    Initial antihypertensive therapy with single-pill combinations produced more rapid blood pressure control than initial monotherapy in clinical trials. Other studies reported better cardiovascular outcomes in patients achieving lower blood pressure during the first treatment year. We assessed the effectiveness of initial antihypertensive monotherapy, free combinations, and single-pill combinations in controlling untreated, uncontrolled hypertensives during their first treatment year. Electronic record data were obtained from 180 practice sites; 106 621 hypertensive patients seen from January 2004 to June 2009 had uncontrolled blood pressure, were untreated for ≥ 6 months before therapy, and had ≥ 1 one-year follow-up blood pressure data. Control was determined by the first follow-up visit with blood pressure blood pressure, body mass index, diabetes mellitus, chronic kidney disease, cardiovascular disease, initial therapy, final blood pressure medication number, and therapeutic inertia. Patients on initial single-pill combinations (N = 9194) were more likely to have stage 2 hypertension than those on free combinations (N = 18 328) or monotherapy (N = 79 099; all Phypertension control in the first year than free combinations (HR, 1.34; [95% CI, 1.31-1.37]) or monotherapy (reference) with benefits in black and white patients. Greater use of single-pill combinations as initial therapy may improve hypertension control and cardiovascular outcomes in the first treatment year.

    Respiratory lung infections due to multidrug-resistant (MDR) superbugs are on a global upsurge and have very grim clinical outcomes. Their MDR profile makes therapeutic options extremely limited. Although a highly toxic antibiotic, colistin, is favored today as a "last-line" therapeutic against these hard-to-treat MDR pathogens, it is fast losing its effectiveness. This work therefore seeks to identify and tailor-make useful combination regimens (that are potentially rotatable and synergistic) as attractive alternative strategies to address the rising rates of drug resistance. Three potentially rotatable ternary dry powder inhaler constructs (each involving colistin and 2 other different-classed antibiotics chosen from rifampicin, meropenem, and tigecycline) were identified (with distinct complementary killing mechanisms), coformulated via spray drying, evaluated on their aerosol performance using a Next-Generation Impactor and tested for their efficacies against a number of MDR pathogens. The powder particles were of respirable size (d50, 3.1 ± 0.3 μm-3.4 ± 0.1 μm) and predominantly crumpled in morphology. When dispersed via a model dry powder inhaler (Aerolizer(®)) at 60 L/min, the powders showed concomitant in vitro deposition with fine particle fractions of ∼53%-70%. All formulations were successfully tested in the laboratory to be highly effective against the MDR pathogens. In addition, a favorable synergistic interaction was detected across all 3 formulations when tested against MDR Pseudomonas aeruginosa.

    In 20 patients with essential arterial hypertension, grade II or III, the haemodynamic effect of a fixed combination of antihypertensive drugs (bemetizide, triamteren, bupranolol and dihydralazine) was studied by percutaneously-introduced flow-guided catheter in the pulmonary artery before, after three weeks and at the end of a six-month period of treatment; systemic arterial blood pressures were measured by the cuff method. Mean pressures, both at rest and on exercise were significantly and persistently lowered. Mean blood pressure at rest fell from 184/110 mmHg before treatment to 167/98 mmHg after three weeks, and to 158/93 mmHg after six months. The initial blood pressure on exercise was 226/129 mmHg, which fell after three weeks to 199/113 mmHg and after six months to 190/106 mmHg. At the same time, pulmonary artery pressure (as a measure of preload) fell by 23% at rest and 30% on exercise. Exercise tolerance of the patients rose by 28%. Pressure-heartrate product fell by 18%, as a pointer to an additional favourable effect on left ventricular oxygen consumption.

  20. The Power of Combination Topical Therapy for Psoriasis.

    Kircik, Leon H; Zografos, Panagiotis

    2015-10-01

    Psoriasis is a chronic inflammatory skin disease where the use of topical corticosteroids is a mainstream treatment. However, the continuous use of high potency topical corticosteroids is limited by a variety of well known adverse events which include, atrophy, and telangiectasia. Also, inhibition of lipid synthesis by steroids can cause impairment of the epidermal barrier, which is already disrupted in most of the inflammatory cutaneous disorders such as psoriasis. This will further lead to increase transepidermal water loss (TEWL), decreased hydration, dry skin, and irritation. On the other hand, topical vitamin D analogs directly affect keratinocyte proliferation and differentiation as well as modulation of epidermal lipids and antimicrobial peptides. Although the exact mechanism of action of topical vitamin D analogs is not well understood in the treatment of psoriasis, their efficacy and safety has been shown in several clinical trials over the years and they are widely used for psoriasis. Therefore, combination of topical steroids and vitamin D analogs may be a logical option for the treatment of psoriasis.

    The hybrid platinum@iron oxide core-shell nanorods with high biocompatibility were synthesized and applied for combined therapy. These hybrid nanorods exhibit a good photothermal effect on cancer cells upon irradiation with a NIR laser. Furthermore, due to the presence of a high atomic number element (platinum core), the hybrid nanorods show a synergistic effect between photothermal and radiation therapy. Therefore, the as-prepared core-shell nanorods could play an important role in facilitating synergistic therapy between photothermal and radiation therapy to achieve better therapeutic efficacy.The hybrid platinum@iron oxide core-shell nanorods with high biocompatibility were synthesized and applied for combined therapy.

    Full Text Available Background: In most studies, patients with schizoaffective disorder (SAD are often combined into one group along with schizophrenia patients or less commonly with those suffering from affective disorders, which makes it difficult to obtain data about the peculiarities of SAD treatment. Articles dedicated to SAD treatment in the interictal period are rare. Methods and Results: The prospective cohort study was conducted from 2011 to 2015. The study involved 86 patients diagnosed with SAD according to ICD-10. Patients received neuroleptics (NLs as antirelapse therapy for 2 years (NL therapy; then mood stabilizers (MSs were added to the antirelapse treatment (NL+MS therapy. The results of this combined therapy with MSs were evaluated after 2 years of treatment. Our results suggest that the use of combination therapy that includes antipsychotics and MSs leads to maintenance of a higher quality remission. Remission becomes more prolonged and affective swings less pronounced, resulting in improved quality of life in SAD patients. Improving the quality of remission can be attributed to the following characteristics of the combined therapy: a the use of lower doses of neuroleptics; b a reduction in the frequency and severity of mood swings; and c an increase in patient compliance. Conclusion: The use of combined pharmacotherapy including antipsychotics and MSs produces a longer, high-quality remission. The inclusion of MSs in the scheme of treatment increases the patient adherence to a medication regimen. The use of MSs in combination therapy reduces affective fluctuations, thereby increasing the probability of maintaining remission with complete symptom relief.

    Full Text Available Nathan M Radcliffe Ophthalmology, New York University, New York, NY, USA Abstract: Glaucomatous optic atrophy is the second most common cause of blindness worldwide, and lowering intraocular pressure (IOP is the only proven method to slow or stop the progression of the disease. Approximately 40% of patients with elevated IOP will require more than one medication to obtain a modest 20% reduction in IOP, and as a result, some patients may require two medications, provided in either two separate bottles or in one bottle with the use of fixed-combination therapies. Each therapy has its own unique safety and efficacy profile. Topical beta-blockers have a particularly favorable ocular-tolerability profile, and several studies of fixed-combination medications containing the beta-blocker timolol maleate have shown a lower prevalence of some ocular adverse events for the fixed-combination therapy compared to the non-beta-blocker individual component. In this review, we examined clinical data pertaining to the ocular surface tolerability of fixed-combination medications containing timolol maleate in comparison to the individual components. In particular, preference was given to prospective, randomized, multicenter trials of 3 months in duration or longer that compared a fixed-combination therapy to monotherapy with the individual components. A review of the literature revealed that some fixed-combination therapies can provide a reduced risk of common side effects compared to their individual components, with conjunctival hyperemia and ocular allergy being less frequent in some timolol-containing fixed-combination therapies. This effect appears to be most significant for latanoprost 0.005%, bimatoprost 0.03%, and brimonidine 0.2%. Keywords: bimatoprost, brimonidine, hyperemia, latanoprost, ocular allergy

Summary Transitioning from individual drugs to an FDC tablet needs to be managed carefully, particularly regarding stock management, ordering processes, supply-chain integrity and comprehensive patient counselling. Priority groups • Initially, FDC supply will be insufficient to provide for all FDC-suitable patients • Therefore, the National Department of Health (NDoH has recommended that the following patient groups be prioritized for FDC initiation/switch: • Priority group 1: All HIV-positive patients newly initiating ART – adults, adolescents and pregnant women (regardless of CD4 count (amendment to the guidelines for the prevention of mother-to-child transmission of HIV (PMTCT anticipated in April 2013 – and who do not have contra-indications to the FDC component drugs • Priority group 2: HIV-positive pregnant women and breastfeeding mothers currently stable on lamivudine (3TC, TDF and EFV • Priority group 3: Virologically suppressed patients on a stavudine (d4T-based regimen and who have normal renal function • Priority group 4: Stable patients receiving individual TDF, 3TC and EFV and who have tuberculosis (TB co-infection • Priority group 5: Stable patients receiving individual TDF, 3TC and EFV and who have other co-morbidites (e.g. hypertension, diabetes • Priority group 6: Patients receiving individual TDF, 3TC and EFV and who request to switch to the FDC treatment • Priority group 7: Patients receiving individual TDF, 3TC and EFV and who, after counselling, agree to switch to the FDC treatment. Important: Clinic staff must co-ordinate this process and only switch as many patients to the FDC tablet as stock allows. This should avoid patients being switched back and forth

    2013-06-01

    β-thalassemias are caused by nearly 300 mutations of the β-globin gene, leading to a low or absent production of adult hemoglobin (HbA). Two major therapeutic approaches have recently been proposed: gene therapy and induction of fetal hemoglobin (HbF) with the objective of achieving clinically relevant levels of Hbs. The objective of this article is to describe the development of therapeutic strategies based on a combination of gene therapy and induction of HbFs. An increase of β-globin gene expression in β-thalassemia cells can be achieved by gene therapy, although de novo production of clinically relevant levels of adult Hb may be difficult to obtain. On the other hand, an increased production of HbF is beneficial in β-thalassemia. The combination of gene therapy and HbF induction appears to be a pertinent strategy to achieve clinically relevant results.

    Full Text Available Cancer stem cells (CSC are considered to be a major driver of cancer progression and successful therapies must control CSCs. However, CSC are often less sensitive to treatment and they might survive radiation and/or chemotherapies. In this paper we combine radiation treatment with differentiation therapy. During differentiation therapy, a differentiation promoting agent is supplied (e.g. TGF-beta such that CSCs differentiate and become more radiosensitive. Then radiation can be used to control them. We consider three types of cancer: head and neck cancer, brain cancers (primary tumors and metastatic brain cancers, and breast cancer; and we use mathematical modelling to show that combination therapy of the above type can have a large beneficial effect for the patient; increasing treatment success and reducing side effects.

Patients control meets the standard management of patients in biological therapy. Results. The study shows that in the case of the resistance progressing when applying preparations of biological therapy, methotrexate is useful at a dose of 15-20mg/week for up to 6 months. The combined use of biologic therapy and methotrexate in the treatment of patients with psoriasis vulgaris, "escape effect" contributes to the marked regression of clinical symptoms and allows to control the process long enough, which is confirmed by the dynamics of the index PASI, BRS and DLQI. The combined method is highly safe, as evidenced by the lack of inhibition of hematopoiesis, the normal level of hepatic transaminases and serum creatinine, which greatly improves patient compliance in this type of therapy. Conclusion. The article presents the data of the combined application of biological medication therapy (ustekinumab and methotrexate for the treatment of patients with the common form of psoriasis vulgaris. In the case of the development of resistance of biological therapy recommended the appointment of methotrexate. The combined use of methotrexate and biologic therapy in the treatment of patients with psoriasis vulgaris contributes to marked regression of clinical symptoms and allows to control the process for a long time.

    Melanoma is the deadliest form of skin cancer and has an incidence that is rising faster than any other solid tumor. Metastatic melanoma treatment has considerably progressed in the past ifve years with the introduction of targeted therapy (BARF and MEK inhibitors) and immune checkpoint blockade (anti-CTLA4, anti-PD-1, and anti-PD-L1). However, each treatment modality has limitations. Treatment with targeted therapy has been associated with a high response rate, but with short-term responses. Conversely, treatment with immune checkpoint blockade has a lower response rate, but with long-term responses. Targeted therapy affects antitumor immunity, and synergy may exist when targeted therapy is combined with immunotherapy. hTis article presents a brief review of the rationale and evidence for the potential synergy between targeted therapy and immune checkpoint blockade. Challenges and directions for future studies are also proposed.

    2015-12-17

    Highly active antiretroviral therapy (ART) has successfully turned Human immunodeficiency virus type 1 (HIV-1) from a deadly pathogen into a manageable chronic infection. ART is a lifelong therapy which is both expensive and toxic, and HIV can become resistant to it. An alternative to lifelong ART is gene therapy that targets the CCR5 co-receptor and creates a population of genetically modified host cells that are less susceptible to viral infection. With generic mathematical models we show that gene therapy that only targets the CCR5 co-receptor fails to suppress HIV-1 (which is in agreement with current data). We predict that the same gene therapy can be markedly improved if it is combined with a suicide gene that is only expressed upon HIV-1 infection.

  18. The role of combination medical therapy in the treatment of acromegaly.

    2017-02-01

    Uncontrolled acromegaly results in approximately 2-fold excess mortality. Pituitary surgery is first-line therapy, and medical treatment is indicated for persistent disease. While cabergoline and pegvisomant are used in select patients, somatostatin receptor ligands (SRLs) remain the cornerstone of medical treatment. Management of patients poorly responsive to SRLs is therefore, challenging. The purpose of this review is to highlight the options for combination medical therapy in the treatment of acromegaly, with an emphasis on efficacy and safety. All original articles/abstracts detailing combination medical therapy in acromegaly were identified from a PubMed search. Studies reviewed included retrospective and open-label prospective studies. While the combination of SRL and cabergoline was generally well tolerated, a lower baseline insulin-like growth factor-1 (IGF-1) level was the best predictor of efficacy; this combination may be most effective in patients with mildly elevated IGF-1. SRL-pegvisomant combination normalized IGF-1 in the majority of patients; continued efficacy despite individual drug dosing reduction was also reported. The risk of significant liver enzyme elevation was, however, higher than that reported with SRL monotherapy; close monitoring is recommended. Data on pegvisomant-cabergoline combination is limited, but this may be an option in the setting of SRL intolerance. Reports on temozolomide used in combination with other medical therapies in patients with aggressive GH-secreting tumors are also summarized. While more prospective, randomized controlled trials on long-term efficacy and safety are needed, combination medical therapy remains a treatment strategy that should be considered for acromegaly patients poorly responsive to SRLs.

    Combination therapy with a long-acting antimuscarinic agent and a long-acting β2-agonist are recommended in chronic obstructive pulmonary disease (COPD) if control is not adequate with one long-acting bronchodilator alone. We evaluated the effects of indacaterol and tiotropium combination therapy, including the effects of adding indacaterol to tiotropium (indacaterol add-on group) and adding tiotropium to indacaterol (tiotropium add-on group). We recruited 79 patients with COPD already treated with tiotropium or indacaterol. We undertook pulmonary function tests, the COPD assessment test (CAT), and the multi-frequency forced oscillation technique (to measure respiratory resistance and reactance) before and after 8 weeks of indacaterol and tiotropium combination therapy. The median age was 72.1 years and the mean forced expiratory volume in 1 s (FEV1) as a proportion of predicted was 57.2 ± 18.3%. After 8 weeks of combination therapy, FEV1 and %predicted FEV1 had increased significantly. There was no change in CAT score. For respiratory impedance, combination therapy improved resistance at 5 Hz (R5) and resistance at 20 Hz (R20) in the whole-breath, inspiratory and expiratory phases, and resonant frequency (Fres) in the inspiratory phase. The indacaterol add-on group (43 patients) and tiotropium add-on group (36 patients) showed improvements in FEV1 and %predicted FEV1 over monotherapy, although the CAT score fell significantly in the indacaterol add-on group (p = 0.005). Indacaterol and tiotropium combination therapy improved airflow limitation and respiratory resistances. Adding indacaterol to tiotropium, or tiotropium to indacaterol, had similar effects on airflow limitation. Copyright © 2014 Elsevier Ltd. All rights reserved.

  1. Targeting the NF-κB Pathway as a Combination Therapy for Advanced Thyroid Cancer.

    Nikita Pozdeyev

    Full Text Available NF-κB signaling plays an important role in tumor cell proliferation, cell survival, angiogenesis, invasion, metastasis and drug/radiation resistance. Combination therapy involving NF-κB pathway inhibition is an attractive strategy for the treatment of advanced forms of thyroid cancer. This study was designed to test the efficacy of NF-κB pathway inhibition in combination with cytotoxic chemotherapy, using docetaxel and ionizing radiation in in vitro models of thyroid cancer. We found that while both docetaxel and ionizing radiation activated NF-κB signaling in thyroid cancer cells, there was no synergistic effect on cell proliferation and/or programmed cell death with either genetic (transduction of a dominant negative mutant form of IκBα or pharmacologic (proteasome inhibitor bortezomib and IKKβ inhibitor GO-Y030 inhibition of the NF-κB pathway in thyroid cancer cell lines BCPAP, 8505C, THJ16T and SW1736. Docetaxel plus bortezomib synergistically decreased in vitro invasion of 8505C cells, but not in the other cell lines. Screening of a panel of clinically relevant targeted therapies for synergy with genetic NF-κB inhibition in a proliferation/cytotoxicity assay identified the histone deacetylase (HDAC inhibitor suberoylanilide hydroxamic acid (SAHA as a potential candidate. However, the synergistic effect was confirmed only in the BCPAP cells. These results indicate that NF-κB inhibitors are unlikely to be beneficial as combination therapy with taxane cytotoxic chemotherapy, external radiation therapy or radioiodine therapy. There may be unique circumstances where NF-κB inhibitors may be considered in combination with docetaxel to reduce tumor invasion or in combination with HDAC inhibitors to reduce tumor growth, but this does not appear to be a combination therapy that could be broadly applied to patients with advanced thyroid cancer. Further research may identify which subsets of patients/tumors may respond to this therapeutic

    From hypertension to diabetes, cancer to HIV, stroke to memory loss and learning disorders to septic shock, male impotence to tuberculosis, there is probably no pathological condition where nitric oxide does not play an important role. Nitric oxide is an analgesic, immune-modulator, vasodilator, anti-apoptotic, growth modulator, angiogenetic, anti-thrombotic, anti-inflammatory and neuro-modulator. Because of the above actions of nitric oxide, many clinical conditions associated with abnormal Nitric oxide (NO) production and bioavailability. Our novel therapeutic approach is to restore the homeostasis of nitric oxide and replace the lost cells by combining nitric oxide therapy, anti-oxidative therapy, low level laser therapy, plasma rich platelet therapy and stem cell therapy.

    Natural killer T (iNKT) cells can help mediate immune surveillance against tumors in mice. Prior studies targeting human iNKT cells were limited to therapy of advanced cancer and led to only modest activation of innate immunity. Clinical myeloma is preceded by an asymptomatic precursor phase. Lenalidomide was shown to mediate antigen-specific costimulation of human iNKT cells. We treated 6 patients with asymptomatic myeloma with 3 cycles of combination of α-galactosylceramide-loaded monocyte-derived dendritic cells and low-dose lenalidomide. Therapy was well tolerated and led to reduction in tumor-associated monoclonal immunoglobulin in 3 of 4 patients with measurable disease. Combination therapy led to activation-induced decline in measurable iNKT cells and activation of NK cells with an increase in NKG2D and CD56 expression. Treatment also led to activation of monocytes with an increase in CD16 expression. Each cycle of therapy was associated with induction of eosinophilia as well as an increase in serum soluble IL2 receptor. Clinical responses correlated with pre-existing or treatment-induced antitumor T-cell immunity. These data demonstrate synergistic activation of several innate immune cells by this combination and the capacity to mediate tumor regression. Combination therapies targeting iNKT cells may be of benefit toward prevention of cancer in humans.

    To evaluate the efficacy and safety of photothermal with dinitrophenyl hapten (DNP) for patients with malignant melanoma (MM), Patients with pathology confirmed stage III or IV MM were enrolled. Seventy-two patients were randomized into two groups, DNP alone group (n=36) and DNP plus photothermal therapy group (n=36). The results showed that the patients in the combination treatment group had longer median progression-free survival time (19.0m vs. 12.0m, p=0.007). No severe adverse events were observed in both groups. Thus, the combination of photothermal therapy and DNP maybe a new therapeutic strategy for patients with advanced MM.

    Although multidrug therapy is required in order to achieve good blood pressure control in many hypertensives, there are no studies directly comparing fixed-dose combinations as initial therapy. The Avoiding Cardiovascular events through COMbination therapy in Patients Living with Systolic Hypertension (ACCOMPLISH) trial compares regimens of benazepril plus amlodipine versus benazepril plus hydrochlorothiazide, force-titrated to 40/10 and 40/25mg, respectively. A total of 12,600 high-risk hypertensives have been randomised and will be followed for 3 - 5years, during which cardiovascular events will be monitored. The investigators hypothesise that the benazepril plus amlodipine regimen will decrease cardiovascular events by 15% compared with benazepril plus hydrochlorothiazide. Recruitment began in 2003, and the trial is expected to end in 2008. The ACCOMPLISH trial shares important limitations with many other recent trials that will make it difficult to apply the results in clinical practice. These include the focus on high-risk hypertensive patients, in whom significant reductions in relative risk will translate into meaningful reductions in absolute risk: in lower-risk hypertensives with a low absolute risk, similar relative risk reductions may not be of great impact on the population disease burden. In ACCOMPLISH, as in most industry-sponsored clinical trials, the main goal appears to be market-driven: doses of drugs tested are not those available for clinical practice. The question asked, whether the combination of benazepril with either diuretic or dihydropyridine calcium channel blocker is more efficacious, is not a clinically compelling one. Finally, the univariate subgroup analyses proposed are unlikely to lead to an understanding of whether either combination has specific advantages for patients encountered clinically, most of whom have multiple risk factors. Thus, it appears that ACCOMPLISH, as with many recent pharmacological trials, will not greatly

In this study, we explore the possibility of treating the disease with a novel combination approach of oleanolic acid (OA, a glycogen phosphorylase (GP inhibitor, and metformin. Methods. Db/db mice were randomly divided into four groups: a db/db control group, db/db mice treated with OA (250 mg/kg, db/db mice treated with metformin (100 mg/kg, and db/db mice treated with a combination of OA and metformin. All mice were treated for four weeks. The effects of the treatments on glucose homeostasis were measured using an OGTT, an assessment of insulin sensitivity and signaling in the liver, and the hepatic glucose production. Results. Combination therapy with OA and metformin significantly reduced the blood glucose and insulin levels and improved the liver pathology compared with that for the monotherapy in the db/db diabetic mouse model. We also found that the combination therapy significantly increased the mRNA expression of glycogen synthesis and decreased the GP, PGC-1α, PEPCK1, and G-6-Pase levels. In addition, the combination therapy with OA and metformin significantly increased the phosphorylation of AKT, PI3K, AMPK, and ACC and decreased the protein expression levels of G-6-Pase, PEPCK1, and TORC compared with those for either monotherapy. The combination therapy also reduced the phosphorylation of mTOR and CREB. Conclusions. Our results suggest that the combination therapy with OA and metformin has synergistic effects on the symptoms of db/db diabetic mice by improving glucose and insulin homeostasis.

    Combination therapy with several antibiotics is one strategy that has been applied in order to limit the spread of antimicrobial resistance. We compared the de novo evolution of resistance during combination therapy with the β-lactam ceftazidime and the fluoroquinolone ciprofloxacin with the resistance evolved after single-drug exposure. Combination therapy selected for mutants that displayed broad-spectrum resistance, and a major resistance mechanism was mutational inactivation of the repressor gene mexR that regulates the multidrug efflux operon mexAB-oprM. Deregulation of this operon led to a broad-spectrum resistance phenotype that decreased susceptibility to the combination of drugs applied during selection as well as to unrelated antibiotic classes. Mutants isolated after single-drug exposure displayed narrow-spectrum resistance and carried mutations in the MexCD-OprJ efflux pump regulator gene nfxB conferring ciprofloxacin resistance, or in the gene encoding the non-essential penicillin-binding protein DacB conferring ceftazidime resistance. Reconstruction of resistance mutations by allelic replacement and in vitro fitness assays revealed that in contrast to single antibiotic use, combination therapy consistently selected for mutants with enhanced fitness expressing broad-spectrum resistance mechanisms.

    This retrospective study investigated the effects of combining manual therapy and acupuncture on the pain and maximal mouth opening (MMO), which were associated with temporomandibular joint dysfunction (TMD). The 49 TMD patients (15 men, 34 women; mean age = 30.47 years, SD = 13.52 years) were treated with a combination of acupuncture and manual therapy two or three times a week at the hospital. The pain and maximal mouth opening were assessed before and after 1 and 4 weeks of treatment. The combination therapy produced significant changes in pain levels (p < 0.001) and mouth opening (p < 0.001). All pairwise non-parametric comparison showed a significant improvement in pain (p < 0.05 for all pairs) and MMO (p < 0.05 for all pairs). These findings suggest that combining manual therapy and acupuncture decreases the pain level and increases the MMO of TMD patients. However, future studies should further investigate the efficacy of combined treatment on TMD with more rigorous randomized clinical trials.

    Full Text Available Aspirin and clopidogrel are usually used individually to prevent adverse cardiovascular events and stroke. They are used in stabilizing the blood pressure in patients of myocardial infarction while combination therapy of aspirin and Clopidogrel (dual anti-platelet therapy is used for preventing adverse cardiovascular events in myocardial infarction patients. A cross-sectional observational study is conducted through a structured questionnaire from 110 patients of K.I.H.D (Karachi Institute of Heart Disease hospital, Karachi, Pakistan. Indoor/admitted patients with diagnosis of acute coronary syndrome (ACS, non-ST elevation myocardial infarction (NSTE-MI, ST elevation myocardial infarction (STE-MI, supra ventricular tachycardia (SVT were included along with those with previous or current onset of angina pectoris or heart attack. Information from the test reports of these patients was included in the data. Patients without proper test reports were excluded from the study. Combination therapy duration is considered as key tool for evaluation. Out of 100 patients (after exclusion criteria applied almost 18% patients were using the combination therapy for 10 to 25 years while 52% of patients were using the combination therapy for 1 to 10 years. Platelet count of 88% patients was found to be in between 1,50,000–3,50,000/µl. Remaining patients had less than 1,50,000 µl to more than 3,50,000 to 4,50,000 µl. Most frequently reported side effects were chest pain, respiratory issues, headache and depression. On the basis of our data analysis it is concluded that long duration dual anti-platelet therapy will not harm platelet count in human blood but it can create drug dependency in patients. Hypertension is not completely cured with this therapy but can help in stabilizing blood pressure.

    Objective Electroconvulsive therapy (ECT) is one of the most effective treatments for severe Major Depressive Disorder (MDD). However, after acute phase treatment and initial remission, relapse rates are significant. Strategies to prolong remission include continuation phase ECT, pharmacotherapy, psychotherapy, or their combinations. This systematic review synthesizes extant data regarding the combined use of psychotherapy with ECT for the treatment of patients with severe MDD and offers the hypothesis that augmenting ECT with depression-specific psychotherapy represents a promising strategy for future investigation. Methods The authors performed two independent searches in PsychInfo (1806 – 2009) and MEDLINE (1948 – 2009) using combinations of the following search terms: Electroconvulsive Therapy (including ECT, ECT therapy, electroshock therapy, EST, shock therapy) and Psychotherapy (including cognitive behavioral, interpersonal, group, psychodynamic, psychoanalytic, individual, eclectic, and supportive). We included in this review a total of six articles (English language) that mentioned ECT and psychotherapy in the abstract, and provided a case report, series, or clinical trial. We examined the articles for data related to ECT and psychotherapy treatment characteristics, cohort characteristics, and therapeutic outcome. Results Although research over the past seven decades documenting the combined use of ECT and psychotherapy is limited, the available evidence suggests that testing this combination has promise and may confer additional, positive functional outcomes. Conclusions Significant methodological variability in ECT and psychotherapy procedures, heterogeneous patient cohorts, and inconsistent outcome measures prevent strong conclusions; however, existing research supports the need for future investigations of combined ECT and psychotherapy in well-designed, controlled clinical studies. Depression-specific psychotherapy approaches may need special

    We analyzed the effectiveness of combination therapy (CT) for idiopathic sudden sensorineural hearing loss (ISSNHL) and the utility of intratympanic dexamethasone injection (ITDI) reapplication as salvage treatment for ISSNHL refractory to CT. Case series with chart review. Academic university hospital. We reviewed 229 patients with ISSNHL and divided these patients into 2 groups according to treatment: systemic steroid therapy (SST) and CT groups. The SST group received prednisolone therapy. The CT group also received ITDI daily. Patients who demonstrated no recovery (Hearing recovery rates were 77.8% (77/99) in the CT group and 60.8% (79/130) in the SST group. The difference was statistically significant (P = .011). Initial pure-tone audiometry and vertigo were affective factors on hearing recovery rates in the CT group. After salvage therapy, hearing improvement of 10 dB or greater was noted in 6 of the 22 (27.3%) patients in the CT group and 16 of the 51 (31.4%) patients in the SST group. The difference in efficacy of salvage therapy between the CT and SST groups was simply not significant (P = .612). Combination therapy was more effective for ISSNHL in achieving hearing gain than SST alone. Furthermore, ITDI reapplication for ISSNHL refractory to CT was as effective as salvage ITDI for ISSNHL refractory to SST. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    SUMMARY Glioblastoma is a common aggressive primary malignant brain tumor, and is nearly universal in progression and mortality after initial treatment. Re-irradiation presents a promising treatment option for progressive disease, both palliating symptoms and potentially extending survival. Highly conformal radiation techniques such as stereotactic radiosurgery and hypofractionated radiosurgery are effective short courses of treatment that allow delivery of high doses of therapeutic radiation with steep dose gradients to protect normal tissue. Patients with higher performance status, younger age, and longer interval between primary treatment and progression represent the best candidates for re-irradiation. Multiple studies are also underway involving combinations of radiation and systemic therapy to bend the survival curve and improve the therapeutic index. In the multimodal treatment of recurrent high-grade glioma, the use of surgery, radiation, and systemic therapy should be highly individualized. Here we comprehensively review radiation therapy and techniques, along with discussion of combination treatment and novel strategies. PMID:26781426

    Full Text Available Results of clinical follow-up of the patient with squamous cell skin carcinoma of the nasal dorsum are represented. The patient underwent a course of combined photodynamic therapy (PDT with distant gamma-ray therapy. Distant gamma-ray therapy was performed daily during 12 days (single dose of 3 Gy, total dose of 36 Gy with the first session 24 h after injection of the photosensitization. For PDT the photosensitizer photosens at dose of 0,3 mg/kg was used. The method of prolonged PDT was applied, sessions of laser irradiation were performed daily during 7 days. The PDT sessions were carried out 2 h after session of gamma-ray therapy using distant (150 J/cm2, 40 mW/cm2 and contact (500 J/cm2, 100 mW/cm2 modalities. According to multiple cytological studies after treatment there were no signs of tumor, but inflammation. Four months after treatment according to cytological data continued tumor growth was detected. The patient underwent an additional course of PDT. Currently the patient is under follow-up: no recurrence during 8 months after repeated treatment.

    Palacios, S; Mejía, A

    2015-01-01

    Osteoporosis is a chronic disease which may require treatment for many years and requires not only individual management but often sequential or combination treatments. Monotherapy with antiresorptives is usually the first choice. Sometimes, it is necessary to modify this option for therapeutic failure or for the time of use and risk of side-effects. Due to their different mode of action, therapy with anabolic drugs has increased our options in the treatment of osteoporosis. Postmenopausal women and men with severe and progressive osteoporosis despite antiresorptive treatment ('therapeutic failure') should be evaluated for treatment with an anabolic option. Moreover, anabolic agents are indicated for 18-24 months in patients at high risk. Then, sequential antiresorptive therapy is recommended to maintain drug increases in bone mass and support secondary mineralization of the newly formed bone. Combination therapies of antiresorptives and anabolic agents have shown a significant increase in bone mineral density compared to monotherapies. However, none of the combinations have been studied for the prevention of fractures. Combination therapy may not be recommended because of the possible increase in cost.

  13. Predictive factors for interferon and ribavirin combination therapy in patients with chronic hepatitis C

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    AIM: To confirm the predictive factors for interferon (IFN)-α and ribavirin combination therapy for chronic hepatitis patients with hepatitis C virus (HCV) genotype 1b.METHODS: HCV RNA from 50 patients infected with HCV genotype 1b was studied by cloning and sequencing of interferon sensitivity determining region (ISDR), PKR-eIF2α phosphorylation homology domain (PePHD).Patients were treated with IFN-α and ribavirin for 6 mo and grouped by effectiveness of the therapy. A variety of factors were analyzed.RESULTS: Our data showed that age, HCV RNA titer,and ISDR type could be used as the predictive factors for combined IFN-α and ribavirin efficacy. Characteristically,mutations in PePHD appeared only when the combination therapy was effective. Other factors, such as sex and alanine aminotransferase (ALT) level, were not related to its efficacy. Adjusting for age and HCV RNA titer indicated that the ISDR type was the most potent predictive factor.CONCLUSION: HCV RNA ISDR type is an important factor for predicting efficacy of IFN-α and ribavirin combination therapy in Korean patients.

    This retrospective review of patients with severe combined immunodeficiency and Pneumocystis jiroveci pneumonia (PCP) evaluated the relationship between duration of therapy to treat PCP and overall survival. We found that 80% of patients receiving only 21 days of antibiotics survived to 12 months beyond hematopoietic cell transplant, whereas only 25% of patients who required longer treatment for PCP survived to stem cell engraftment.

  15. Can the combination of localized "proliferative therapy" with "minor ozonated autohemotherapy" restore the natural healing process?

    Science.gov (United States)

    Gracer, R I; Bocci, V

    2005-01-01

    Regenerative injection therapy (RIT), also known as proliferative therapy, has been used for over 30 years in the USA in patients with spinal and peripheral joint and ligamentous pathologies. It involves the injection of mildly irritating medications onto ligaments and tendons, most commonly at origins and insertions. These injections cause a mild inflammatory response which "turns on" the normal healing process and results in the regeneration of these structures. At the same time they strengthen and become less sensitive to pain through a combination of neurolysis of small nerve fibers (C-fibers) and increased stability of the underlying structures. Oxygen/ozone therapy is a well established complementary therapy practiced in many European countries. The ozone dissolves in body fluids and immediately reacts with biomolecules generating messengers responsible for biological and therapeutic activities. This results in an anti inflammatory response, which also results in a similar trophic reaction to that of RIT. It is logical to expect that combining these two modalities would result in enhanced healing and therefore improved clinical outcomes. Oxygen/ozone therapy, accomplished by autohemotherapy (AHT), is performed by either administering ozonated blood intravenously (Major AHT) or via intramuscular route (Minor AHT). These procedures result in stimulation of the immune and healing systems. Our concept is that the local injection of this activated blood injected directly to the ligamentous areas that are also being treated with RIT will act as a direct stimulation to the healing process. In addition, combining this with intravenous major AHT should stimulate the immune system to augment and support this process. RIT and oxygen/ozone therapy have been extensively studied separately. We propose a study of lumbosacral ligamentous pain to explore this therapeutic combination. We hope that this paper will stimulate general interest in this area of medicine and result

  16. Ribavirin-induced anemia in hepatitis C virus patients undergoing combination therapy.

    Directory of Open Access Journals (Sweden)

    Sheeja M Krishnan

    Full Text Available The current standard of care for hepatitis C virus (HCV infection - combination therapy with pegylated interferon and ribavirin - elicits sustained responses in only ∼50% of the patients treated. No alternatives exist for patients who do not respond to combination therapy. Addition of ribavirin substantially improves response rates to interferon and lowers relapse rates following the cessation of therapy, suggesting that increasing ribavirin exposure may further improve treatment response. A key limitation, however, is the toxic side-effect of ribavirin, hemolytic anemia, which often necessitates a reduction of ribavirin dosage and compromises treatment response. Maximizing treatment response thus requires striking a balance between the antiviral and hemolytic activities of ribavirin. Current models of viral kinetics describe the enhancement of treatment response due to ribavirin. Ribavirin-induced anemia, however, remains poorly understood and precludes rational optimization of combination therapy. Here, we develop a new mathematical model of the population dynamics of erythrocytes that quantitatively describes ribavirin-induced anemia in HCV patients. Based on the assumption that ribavirin accumulation decreases erythrocyte lifespan in a dose-dependent manner, model predictions capture several independent experimental observations of the accumulation of ribavirin in erythrocytes and the resulting decline of hemoglobin in HCV patients undergoing combination therapy, estimate the reduced erythrocyte lifespan during therapy, and describe inter-patient variations in the severity of ribavirin-induced anemia. Further, model predictions estimate the threshold ribavirin exposure beyond which anemia becomes intolerable and suggest guidelines for the usage of growth hormones, such as erythropoietin, that stimulate erythrocyte production and avert the reduction of ribavirin dosage, thereby improving treatment response. Our model thus facilitates, in

    Full Text Available Abstract Background: The efficacy of combined psychotherapy and benzodiazepine treatment for panic disorder is still unclear despite its widespread use. The present systematic review aims to examine its efficacy compared with either monotherapy alone. Methods: All randomised trials comparing combined psychotherapy and benzodiazepine for panic disorder with either therapy alone were identified by comprehensive electronic search on the Cochrane Registers, by checking references of relevant studies and of other reviews, and by contacting experts in the field. Two reviewers independently checked eligibility of trials, assessed quality of trials and extracted data from eligible trials using a standardized data extraction form. Our primary outcome was "response" defined by global judgement. Authors of the original trials were contacted for further unpublished data. Meta-analyses were undertaken synthesizing data from all relevant trials. Results: Only two studies, which compared the combination with behaviour (exposure therapy, met our eligibility criteria. Both studies had a 16-week intervention. Unpublished data were retrieved for one study. The relative risk for response for the combination was 1.25 (95%CI: 0.78 to 2.03 during acute phase treatment, 0.78 (0.45 to 1.35 at the end of treatment, and 0.62 (0.36 to 1.07 at 6–12 months follow-up. Some secondary outcomes hinted at superiority of the combination during acute phase treatment. One study was identified comparing the combination to benzodiazepine. The relative risk for response was 1.57 (0.83 to 2.98, 3.39 (1.03 to 11.21, statistically significant and 2.31 (0.79 to 6.74 respectively. The superiority of the combination was observed on secondary outcomes at all the time points. No sub-group analyses were conducted due to the limited number of included trials. Conclusion: Unlike some narrative reviews in the literature, our systematic search established the paucity of high quality evidence for

    2011-03-01

    Full Text Available Abstract Background Pain in general and headache in particular are characterized by a change in activity in brain areas involved in pain processing. The therapeutic challenge is to identify drugs with molecular targets that restore the healthy state, resulting in meaningful pain relief or even freedom from pain. Different aspects of pain perception, i.e. sensory and affective components, also explain why there is not just one single target structure for therapeutic approaches to pain. A network of brain areas ("pain matrix" are involved in pain perception and pain control. This diversification of the pain system explains why a wide range of molecularly different substances can be used in the treatment of different pain states and why in recent years more and more studies have described a superior efficacy of a precise multi-target combination therapy compared to therapy with monotherapeutics. Discussion In this article, we discuss the available literature on the effects of several fixed-dose combinations in the treatment of headaches and discuss the evidence in support of the role of combination therapy in the pharmacotherapy of pain, particularly of headaches. The scientific rationale behind multi-target combinations is the therapeutic benefit that could not be achieved by the individual constituents and that the single substances of the combinations act together additively or even multiplicatively and cooperate to achieve a completeness of the desired therapeutic effect. As an example the fixesd-dose combination of acetylsalicylic acid (ASA, paracetamol (acetaminophen and caffeine is reviewed in detail. The major advantage of using such a fixed combination is that the active ingredients act on different but distinct molecular targets and thus are able to act on more signalling cascades involved in pain than most single analgesics without adding more side effects to the therapy. Summary Multitarget therapeutics like combined analgesics broaden

Several clinical studies indicate the high efficacy of antihypertensive combinations, and recent guidelines recommend them in some situations even as initial therapies. In general practice they seem widespread, but only limited data are available on their effectiveness under the conditions of everyday life. The objectives of this survey among Swiss primary care physicians treating hypertensive patients were: to know the frequency of application of different treatment modalities (monotherapies, free individual combinations, single-pill combinations; to see whether there are relationships between prescribed treatment modalities and patient characteristics, especially age, treatment duration, and comorbidities; and to determine the response rate (percentage of patients reaching target BP of different treatment modalities under the conditions of daily practice. Methods: This cross-sectional, observational survey among 228 randomly chosen Swiss primary care physicians analyzed data for 3,888 consecutive hypertensive patients collected at one single consultation. Results: In this survey, 31.9% of patients received monotherapy, 41.2% two substances, 20.9% three substances, and 4.7% more than three substances. By combination mode, 34.9% took free individual combinations and 30.0% took fixed-dose single-pill combinations. Combinations were more frequently given to older patients with a long history of hypertension and/or comorbidities. In total, 67.8% of patients achieved their BP target according to their physician's judgment. When compared, single

The combined treatment (ADT–EBRT also seems to play a significant role in improving treatment results in the intermediate-risk group of prostate cancer patients. On the other hand, there is a growing body of evidence that treatment with ADT can be associated with serious and lifelong adverse events including osteoporosis, cardiovascular disease, diabetes, and many others. Almost all ADT adverse events are time dependant and tend to increase in severity with prolongation of hormonal manipulation. Therefore, it is crucial to clearly state the optimal schedule for ADT in combination with EBRT, that maintaining the positive effect on treatment efficacy would keep the adverse events risk at reasonable level. To achieve this goal, treatment schedule may have to be highly individualized on the basis of the patient-specific potential vulnerability to adverse events. In this study, the concise and evidence-based review of current literature concerning the general rationales for combining radiotherapy and hormonal therapy, its mechanism, treatment results, and toxicity profile is presented.Keywords: prostate cancer, radiotherapy, androgen deprivation, combined treatment

    Catechins and caffeine, which are green tea components, have a slimming effect; however, the combinational effect of fat metabolism in 3T3-L1 cells remains unclear. In the present study, 3T3-L1 cells were treated with catechins and caffeine in combination, and it was found that combination therapy with catechins and caffeine markedly reduced intracellular fat accumulation, mRNA expression levels of peroxisome proliferator-activated receptor-γ and CCAAT/enhancer-binding protein α in the early stage of cell differentiation were significantly reduced, and mRNA expression of fatty acid synthetase(FAS) andglycerol-3-phosphate dehydrogenase protein expression levels of FAS were downregulated. Noradrenaline-induced lipolysis was enhanced by caffeine, which markedly increased the protein expression of adipose triglyceride lipase and hormone sensitive lipase. These results indicated that combination therapy with catechins and caffeine synergistically inhibited lipid accumulation by regulating the gene and protein expression levels of lipid metabolism-related enzymes. Therefore, catechins and caffeine combination therapy has potential as a functional food that may be used to prevent obesity and lifestyle-associated diseases. PMID:28352352

    AIM To observe the therapeutic effect of corneal collagen cross-linking (CXL) in combination with liposomal amphotericin B in fungal corneal ulcers. METHODS New Zealand rabbits were induced fungal corneal ulcers by scratching and randomly divided into 3 groups, i.e. control, treated with CXL, and combined therapy of CXL with 0.25% liposomal amphotericin B (n=5 each). The corneal lesions were documented with slit-lamp and confocal microscopy on 3, 7, 14, 21 and 28d after treatment. The corneas were examined with transmission electron microscopy (TEM) at 4wk. RESULTS A rabbit corneal ulcer model of Fusarium was successfully established. The corneal epithelium defect areas in the two treatment groups were smaller than that in the control group on 3, 7, 14 and 21d (Pulcers. The combined therapy could alleviate corneal inflammattions, accelerate corneal repair, and shorten the course of disease. PMID:27990355

    Full Text Available Recent discoveries of direct acting antivirals against Hepatitis C virus (HCV have raised hopes of effective treatment via combination therapies. Yet rapid evolution and high diversity of HCV populations, combined with the reality of suboptimal treatment adherence, make drug resistance a clinical and public health concern. We develop a general model incorporating viral dynamics and pharmacokinetics/ pharmacodynamics to assess how suboptimal adherence affects resistance development and clinical outcomes. We derive design principles and adaptive treatment strategies, identifying a high-risk period when missing doses is particularly risky for de novo resistance, and quantifying the number of additional doses needed to compensate when doses are missed. Using data from large-scale resistance assays, we demonstrate that the risk of resistance can be reduced substantially by applying these principles to a combination therapy of daclatasvir and asunaprevir. By providing a mechanistic framework to link patient characteristics to the risk of resistance, these findings show the potential of rational treatment design.

    Aim: To study the effect of combined androgen block therapy on hemoglobin and hematocrit values in patients with prostate cancer. Methods: One hundred and thirty-six patients with adenocarcinoma of prostate were treated with combined androgen block (orchiectomy and flutamide 250 mg, tid). Complete blood counts were determined before and after 1,2,3,6,9 and 12 months of therapy. Results: The hemoglobin and hematocrit levels declined significantly in all patients and at all the time points after treatment (P<0.05). Conclusion: Prostate cancer patients treated with combined androgen block would develop obvious anemia. Recombinant human erythropoietin can be used to treat patients with severe anemia.

    Positioning therapy may improve lung recruitment and oxygenation and is part of the standard care in severe acute respiratory distress syndrome (ARDS). Venovenous extracorporeal membrane oxygenation (vvECMO) is a rescue strategy that may ensure sufficient gas exchange in ARDS patients failing conventional therapy. The aim of this case series was to describe the feasibility and pitfalls of combining positioning therapy and vvECMO in patients with severe ARDS. A retrospective cohort of nine patients is described. The patients received 20 (15-86) hours (median, 25(th) and 75(th) percentile) of positioning therapy while being treated with vvECMO. The initial PaO2/FiO2 index was 64 (51-67) mmHg and the arterial carbon dioxide tension was 60 (50-71) mmHg. Positioning therapy included 135 degrees prone, prone positioning and continuous lateral rotational therapy. During the first three days, the oxygenation index improved from 47 (41-47) to 12 (11-14) cmH2O/mmHg. The lung compliance improved from 20 (17-28) to 42 (27-43) ml/cmH2O. Complications related to positioning therapy were facial oedema (n=9); complications related to vvECMO were entrance of air (n=1) and pump failure (n=1). However, investigation of root causes revealed no association with the positioning therapy and had no documented effect on the outcome. The reported cases suggest that positioning therapy can be performed safely in ARDS patients treated with vvECMO, providing appropriate precautions are in place and a very experienced team is present.

    Full Text Available Background: Combination therapy with antihypertensive agents utilises different mechanisms of action and may be responsible for a more effective decrease in blood pressure. Objective: To review the recently published trials on efficacy and safety of the combination therapy with olmesartan and amlodipine. Results: The double-blind American COACH (Combination of Olmesartan Medoxomil and Amlopdine Besylate in Controlling High Blood Pressure study (2008 showed in 1,940 patients that after eight weeks of treatment the BP goals were most frequently achieved in the ‘combination therapy group’, with 56.3% (54.1–58.5% and 54.0% (51.8–56.2% of patients reaching adequate blood pressure of <140/90 mmHg with olmesartan/amlodipine 20/10 and 40/10 respectively. Combination therapy was generally well tolerated. The most common side effect was oedema [olmesartan 20 mg 9.9% (8.6–11.3%, amlodipine 10 mg 36.8% (34.7–39.0%, placebo 12.3% (10.9–13.8%]. The frequency of oedema was lower in the groups combining amlodipine 10 mg with olmesartan 10 mg (26.5%, 24.5–28.5%, 20 mg (25.6%, 23.7–27.6% or 40 mg (23.5%, 21.6–25.4%. In 2009 three double-blind controlled European studies including 500–1,000 patients each and performed independently of one another have confirmed the above study, and have demonstrated similar efficacy-safety effects from the combination of olmesartan medoxomil with amlodipine, particularly for patients not achieving adequate blood pressure control with olmesartan monotherapy. Conclusions: Combinations of olmesartan and amlodipine were significantly more effective at reducing blood pressure and realising guideline blood pressure goals in patients with mild to severe hypertension than monotherapy (with a placebo component. Combination therapy is well tolerated and is associated with a lower incidence of side effects, such as oedema, compared to monotherapy with high amlodipine dosages (10 mg.

    A 26-year-old man diagnosed with nephrotic syndrome was administered steroid monotherapy. Urinary protein excretion was 2-3 g/day despite the therapy. Percutaneous renal biopsy revealed Type I idiopathic membranoproliferative glomerulonephritis (IMPGN). Although intravenous steroid therapy at the dose of 1,000 mg/day for 3 days was administered, proteinuria persisted at the level of 1 g/day. Renal dysfunction (cystatin C, 1.33 mg/L) was evident. Strong inflammation was suggested by occult blood (3+) and urinary (red blood cells: 30-50/high power field) sediment. We considered steroid monotherapy to be ineffective, and initiated combina-tion therapy with mycophenolate mofetil (MMF) and steroids. Consequently, urinary protein excretion moderately decreased to 0.34 g/day without adverse events or worsening of the renal function. The steroid quantity could be reduced without relapse. Subsequently, we were able to reduce the dose of MMF gradually, then terminated the medication. IMPGN is a rare disease with a poor renal prognosis. Recently, MMF therapies for IMPGN have been attempted, but there are few cases in Japan. Our case suggests that combination therapy with MMF and steroids is effective and safe for treating IMPGN.

    Full Text Available Abstract Introduction Clinical evidence indicates that certain types of movement disorders are due to psychosomatic factors. Patients with myoclonic movements are usually treated by a variety of therapeutic agents. Autogenic training (AT, a recognized form of psychosomatic therapies, is suitable for certain types of neurological diseases. We describe a patient with myoclonus who failed to respond to conventional medical therapy. His symptoms were exaggerated by psychogenic factors, especially anger. Case presentation A 42-year-old man was admitted to our hospital, Preventive Welfare Clinic, for severe paroxysmal axial myoclonus of the left shoulder and abdominal muscles. The initial diagnosis was "combination of spinal segmental myoclonus and propriospinal myoclonus". The myoclonic movements did not occur during sleep but were aggravated by bathing, alcohol drinking, and anger. Psychological examination indicated hostile attribution. Although considered not to be a case of psychogenic myoclonus, a "psychogenic factor" was definitely involved in the induction of the organic myoclonus. The final diagnosis was "combination of spinal segmental myoclonus and propriospinal myoclonus accompanied by features of psychosomatic disorders". The patient underwent psychosomatic therapy including AT and surface electromyography (EMG-biofeedback therapy and treatment with clonazepam and carbamazepine. Results AT and EMG-biofeedback resulted in shortening the duration and reducing the amplitude and frequency of the myoclonic discharges. Conclusion Psychosomatic therapy with AT and surface EMG-biofeedback produced excellent improvement of myoclonic movements and allowed the reduction of the dosage of conventional medications.

    Despite aggressive conventional therapy, lasting hemiplegia persists in a large percentage of stroke survivors. The aim of this article is to critically review the rationale behind targeting multiple sites along the motor learning network by combining robotic therapy with pharmacotherapy and virtual reality-based reward learning to alleviate upper extremity impairment in stroke survivors. Methods for personalizing pharmacologic facilitation to each individual's unique biology are also reviewed. At the molecular level, treatment with levodopa was shown to induce long-term potentiation-like and practice-dependent plasticity. Clinically, trials combining conventional therapy with levodopa in stroke survivors yielded statistically significant but clinically unconvincing outcomes because of limited personalization, standardization, and reproducibility. Robotic therapy can induce neuroplasticity by delivering intensive, reproducible, and functionally meaningful interventions that are objective enough for the rigors of research. Robotic therapy also provides an apt platform for virtual reality, which boosts learning by engaging reward circuits. The future of stroke rehabilitation should target distinct molecular, synaptic, and cortical sites through personalized multimodal treatments to maximize motor recovery.

    The photo-based therapeutic approaches have attracted tremendous attention in recent years especially in treatment and management of tumors. Photodynamic and photothermal are two major therapeutic modalities which are being applied in clinical therapy. The development of nanomaterials for photodynamic combined with photothermal therapy has gained significant attention for its treatment efficacy. In the present study, we designed chlorin e6 (Ce6) conjugated copper sulfide (CuS) nanoparticles (CuS-Ce6 NPs) through amine functionalization and the synthesized nanoparticles act as a dual-model agent for photodynamic therapy and photothermal therapy. CuS-Ce6 NPs showed enhanced photodynamic effect through generation of singlet oxygen upon 670nm laser illumination. The same nanoparticles exerted thermal response under an 808nm laser at 2W/cm(2). The fabricated nanoparticles did not show any cytotoxic effect toward breast cancer cells in the absence of light. In vitro cell viability assay showed a potent cytotoxicity in photothermal and photodynamic treatment. Rather than singular treatment, the photodynamic combined photothermal treatment showed an enhanced cytotoxic effect on treated cells. In addition, the CuS-Ce6 NPs exert a photoacoustic signal for non-invasive imaging of treated cells in tissue-mimicking phantom. In conclusion the CuS-Ce6 NPs act as multimodal agent for photo based imaging and therapy. Copyright © 2017 Elsevier B.V. All rights reserved.

    2016-01-01

    Treatment with BRAF inhibitors such as vemurafenib or dabrafenib in patients with advanced BRAFV600 mutated melanoma has shown objective tumor responses in approximately half of the patients. However, the duration of responses is limited in a majority of these patients, with progression-free survival rates around 6 months due to tumor progression from development of acquired resistance. Preclinical studies have suggested that concurrent inhibition of the BRAF kinases and MEK of the mitogen-activated protein kinase (MAPK) pathway could decrease MAPK-driven acquired resistance, resulting in longer duration of responses, higher rate of tumor responses, and a decrease in the cutaneous toxicities observed from paradoxical MAPK pathway activation with BRAF inhibitor monotherapy. This review provides an overview of the currently available clinical trial data on BRAF and MEK inhibitors together and in combinations with other therapeutic agents. PMID:26753005

    The objective of this study was to evaluate the effects of combination therapy with methylene blue (MB) assisted photodynamic therapy (PDT) and salicylic acid (SA) as chemo-therapy anticancer agent. The binding of salicylic acid to methylene blue was studied using spectrophotometric method. The results show the 1:2 complex formation between SA and MB. The binding constants and related Gibbs free energies o are obtained (Kb1 = 183.74, Kb2 = 38.13 and ∆ Gb1° = 12.92 kJ·mol- 1, ∆ Gb2° =9.02 kJ·mol- 1). The spectrophotometric results show the improvement in solubilization and reduction prevention for SA and MB in the complex form. These results are in agreements with cellular experiments. The dark toxicity measurements represent the improve efficacy of chemotherapy using combination of SA and MB. The photodynamic therapy results (using red LED as light source (630 nm; power density: 30 mW cm- 2)) show that the cancer cell killing efficiency of MB increases in the combination with SA due to reduction prevention and stabilization of monomeric form of MB.

    Background: Adequate therapy for chronic invasive rhinocerebral aspergillosis in immunocompetent patients is controversial. The incidence of the disease is high in the Sudan and the Middle East. Misinterpretation of diagnostic criteria, failure to verify tissue invasion of fungi, and a lack of understanding of the pathophysiology of various forms of fungal rhinosinusitis lead to controversies in nomenclature, diagnosis, and therapy. Objective: The aim of this report was to detail the clinical presentation and the endoscopic and imaging study findings of a patient with invasive Aspergillus rhinosinusitis with endocranial and orbital extension. This patient was treated with surgical débridement and a combination of antifungal drugs and immunomodulatory therapy. Methods: Endoscopic débridement and high-dose liposomal amphotericin B, in combination with flucytosine and immunomodulators, were used to treat this patient. Results: After treatment, the patient experienced 3 years of disease-free follow-up. Conclusion: Surgical débridement and high-dose systemic combined antifungal therapy with immunomodulatory drugs produced an excellent long-term result for this apparently immunocompetent patient with extensive invasive fungal rhinosinusitis with cerebral and orbital involvement.

Prevention of exacerbations is thus an important goal of COPD management. In patients with COPD, treatment with a combination of the inhaled corticosteroid fluticasone propionate (250 μg and the long-acting β2-agonist salmeterol (50 μg in a single inhaler (250/50 μg is an effective therapy option that has been shown to reduce the frequency of exacerbations, to improve lung function, dyspnea and health status, and to be relatively cost-effective as a COPD maintenance therapy. Importantly, results of various studies suggest that fluticasone propionate and salmeterol have synergistic effects when administered together that improve their efficacy in controlling symptoms and reducing exacerbations. The present non-systematic review summarizes the role of fluticasone propionate/salmeterol combination therapy in the prevention of exacerbations of COPD and its related effects on lung function, survival, health status, and healthcare costs.Keywords: Advair, COPD, disease exacerbation, fluticasone propionate, salmeterol, combination drug therapy

    Cancer combination therapy to treat tumors with different therapeutic approaches can efficiently improve treatment efficacy and reduce side effects. Herein, we develop a theranostic nano-platform based on polydopamine (PDA) nanoparticles, which then are exploited as a versatile carrier to allow simultaneous loading of indocyanine green (ICG), doxorubicin (DOX) and manganese ions (PDA-ICG-PEG/DOX(Mn)), to enable imaging-guided chemo & photothermal cancer therapy. In this system, ICG acts as a photothermal agent, which shows red-shifted near-infrared (NIR) absorbance and enhanced photostability compared with free ICG. DOX, a model chemotherapy drug, is then loaded onto the surface of PDA-ICG-PEG with high efficiency. With Mn(2+) ions intrinsically chelated, PDA-ICG-PEG/DOX(Mn) is able to offer contrast under T1-weighted magnetic resonance (MR) imaging. In a mouse tumor model, the MR imaging-guided combined chemo- & photothermal therapy achieves a remarkable synergistic therapeutic effect compared with the respective single treatment modality. This work demonstrates that PDA nanoparticles could serve as a versatile molecular loading platform for MR imaging guided combined chemo- & photothermal therapy with minimal side effects, showing great potential for cancer theranostics.

  18. Genetic variability of hepatitis C virus before and after combined therapy of interferon plus ribavirin.

    Directory of Open Access Journals (Sweden)

    José Manuel Cuevas

    Full Text Available We present an analysis of the selective forces acting on two hepatitis C virus genome regions previously postulated to be involved in the viral response to combined antiviral therapy. One includes the three hypervariable regions in the envelope E2 glycoprotein, and the other encompasses the PKR binding domain and the V3 domain in the NS5A region. We used a cohort of 22 non-responder patients to combined therapy (interferon alpha-2a plus ribavirin for which samples were obtained before initiation of therapy and after 6 or/and 12 months of treatment. A range of 25-100 clones per patient, genome region and time sample were sequenced. These were used to detect general patterns of adaptation, to identify particular adaptation mechanisms and to analyze the patterns of evolutionary change in both genome regions. These analyses failed to detect a common adaptive mechanism for the lack of response to antiviral treatment in these patients. On the contrary, a wide range of situations were observed, from patients showing no positively selected sites to others with many, and with completely different topologies in the reconstructed phylogenetic trees. Altogether, these results suggest that viral strategies to evade selection pressure from the immune system and antiviral therapies do not result from a single mechanism and they are likely based on a range of different alternatives, in which several different changes, or their combination, along the HCV genome confer viruses the ability to overcome strong selective pressures.

    Tinnitus is a phantom perception of sound in the absence of overt acoustic stimulation. The focus of our attention is a combined therapy of tinnitus. In this prospective study (2013-2014) we evaluated the data of normal-hearing patients with tinnitus treated with various treatment modalities. In Group 1 we evaluated the data of 84 patients/124 ears after six weeks of treatment with betahistine dihydrochloride (72 mg). In Group 2, we evaluated the data of 36 patients/ 55 ears unimproved from Group 1 who were then treated for six weeks with hyperbaric oxygen (HBO₂) therapy combined with gingko biloba extract (120 mg). In Group 1, tinnitus disappeared in 9.7%, alleviated in 18.5% and improved overall in 28.2%. Average intensity of tinnitus before/after treatment was 37 decibels (dB)/33 dB. Tinnitus intensities after treatment are statistically significantly lower (p = 0.001) than the values before treatment. In Group 2 tinnitus disappeared in 5.4%, 36.4% achieved alleviation, and 41.8% showed overall improvement. The average intensity of tinnitus before/after treatment was 41dB/ 38dB. The values of tinnitus intensity after combined therapy are statistically significantly lower (p = 0.046). We have shown that both methods treatment of tinnitus are statistically significant. HBO₂therapy was recommended for the general public.

    In this investigation, we have designed and synthesized a novel core-shell polymer nanoparticle system for highly effective chemo-photothermal combination therapy. A nanoscale DSPE-PEG micelle encapsulating doxorubicin (Dox-M) was designed as a core, and then modified by a polydopamine (PDA) shell for photothermal therapy and bortezomib (Btz) administration (Dox-M@PDA-Btz). The facile conjugation of Btz to the catechol-containing PDA shell can form a reversible pH-sensitive boronic acid-catechol conjugate to create a stimuli-responsive drug carrier system. As expected, the micelle@PDA core-shell nanoparticles exhibited satisfactory photothermal efficiency, which has potential for thermal ablation of malignant tissues. In addition, on account of the PDA modification, both Dox and Btz release processes were pH-dependent and NIR-dependent. Both in vitro and in vivo studies illustrated that the Dox-M@PDA-Btz nanoparticles coupled with laser irradiation could enhance the cytotoxicity, and thus combinational therapy efficacy was achieved when integrating Dox, Btz, and PDA into a single nanoplatform. Altogether, our current study indicated that the micelle@polydopamine core-shell nanoparticles could be applied for NIR/pH-responsive sustained-release and synergized chemo-photothermal therapy for breast cancer.In this investigation, we have designed and synthesized a novel core-shell polymer nanoparticle system for highly effective chemo-photothermal combination therapy.

    Current treatments for vitiligo are largely unsatisfactory. Topical corticosteroids and phototherapy (narrow-band UVB and psoralen+UVA) are the most prescribed, however, these therapies are often not effective and have important side-effect, especially when used for a long time. Many studies have reported the efficacy and safety of tacrolimus ointment in adults and children with vitiligo, particularly when located on the head and neck. Successful treatment is possible when it is combined with other therapies, such as narrow-band UVB, microphototherapy, helium-neon laser, or narrow-band excimer laser.

    Vascular dysfunction, including impaired perfusion has a pivotal role in the pathogenesis of microvascular complications in diabetes mellitus. Both pentoxifylline (PF) and pentosan polysulphate (PPS) are known to improve microcirculation. Antioxidant and antiproteinuric effects of PF are also known. In a placebo-controlled study, we determined the possible efficacy of PF-PPS combination therapy on diabetic neuropathy and nephropathy in type 2 diabetic patients. Patients in Verum group (n = 77) received PF-PPS infusions (100-100 mg/day) for 5 days. Control diabetics (Placebo group; n = 12) were given only saline infusions. Specialized cardiovascular autonomic reflex tests, vibration threshold values and urinary albumin excretion were assessed before and after therapy. In Verum group, autonomic score, indicating the severity of cardiac autonomic dysfunction, decreased after therapy (p < or = 0.001). Of the reflexes, deep breath and handgrip tests also improved after therapy (p < or = 0.001). Vibration threshold values, an indicator of the loss of sensory nerve function, were increased after therapy (p < or = 0.001). Results of cardiac autonomic tests and vibration threshold values remained unaltered in Placebo group. Majority of patients had normalbuminuria, which was not affected by PF-PPS. In conclusion, short-term PF-PPS therapy was effective on cardiovascular autonomic function and vibration perception, whereas it failed to reduce albuminuria within normal range in type 2 diabetic patients.

    Recent breakthroughs in the treatment of advanced melanoma are based on scientific advances in understanding oncogenic signaling and the immunobiology of this cancer. Targeted therapy can successfully block oncogenic signaling in BRAF(V600)-mutant melanoma with high initial clinical responses, but relapse rates are also high. Activation of an immune response by releasing inhibitory check points can induce durable responses in a subset of patients with melanoma. These advances have driven interest in combining both modes of therapy with the goal of achieving high response rates with prolonged duration. Combining BRAF inhibitors and immunotherapy can specifically target the BRAF(V600) driver mutation in the tumor cells and potentially sensitize the immune system to target tumors. However, it is becoming evident that the effects of paradoxical mitogen-activated protein kinase pathway activation by BRAF inhibitors in non-BRAF-mutant cells needs to be taken into account, which may be implicated in the problems encountered in the first clinical trial testing a combination of the BRAF inhibitor vemurafenib with ipilimumab (anti-CTLA4), with significant liver toxicities. Here, we present the concept and potential mechanisms of combinatorial activity of targeted therapy and immunotherapy, review the literature for evidence to support the combination, and discuss the potential challenges and future directions for rational conduct of clinical trials.

    Androgen-deprivation therapy (ADT) is used routinely in combination with definitive external beam radiation therapy (EBRT) in patients with high-risk clinically localized or locally advanced disease. The combined treatment (ADT-EBRT) also seems to play a significant role in improving treatment results in the intermediate-risk group of prostate cancer patients. On the other hand, there is a growing body of evidence that treatment with ADT can be associated with serious and lifelong adverse events including osteoporosis, cardiovascular disease, diabetes, and many others. Almost all ADT adverse events are time dependant and tend to increase in severity with prolongation of hormonal manipulation. Therefore, it is crucial to clearly state the optimal schedule for ADT in combination with EBRT, that maintaining the positive effect on treatment efficacy would keep the adverse events risk at reasonable level. To achieve this goal, treatment schedule may have to be highly individualized on the basis of the patient-specific potential vulnerability to adverse events. In this study, the concise and evidence-based review of current literature concerning the general rationales for combining radiotherapy and hormonal therapy, its mechanism, treatment results, and toxicity profile is presented.

    Full Text Available BACKGROUND: Visceral leishmaniasis is a systemic parasitic disease that is fatal unless treated. We assessed the cost and cost-effectiveness of alternative strategies for the treatment of visceral leishmaniasis in the Indian subcontinent. In particular we examined whether combination therapies are a cost-effective alternative compared to monotherapies. METHODS AND FINDINGS: We assessed the cost-effectiveness of all possible mono- and combination therapies for the treatment of visceral leishmaniasis in the Indian subcontinent (India, Nepal and Bangladesh from a societal perspective using a decision analytical model based on a decision tree. Primary data collected in each country was combined with data from the literature and an expert poll (Delphi method. The cost per patient treated and average and incremental cost-effectiveness ratios expressed as cost per death averted were calculated. Extensive sensitivity analysis was done to evaluate the robustness of our estimations and conclusions. With a cost of US$92 per death averted, the combination miltefosine-paromomycin was the most cost-effective treatment strategy. The next best alternative was a combination of liposomal amphotericin B with paromomycin with an incremental cost-effectiveness of $652 per death averted. All other strategies were dominated with the exception of a single dose of 10mg per kg of liposomal amphotericin B. While strategies based on liposomal amphotericin B (AmBisome were found to be the most effective, its current drug cost of US$20 per vial resulted in a higher average cost-effectiveness. Sensitivity analysis showed the conclusion to be robust to variations in the input parameters over their plausible range. CONCLUSIONS: Combination treatments are a cost-effective alternative to current monotherapy for VL. Given their expected impact on the emergence of drug resistance, a switch to combination therapy should be considered once final results from clinical trials are

    Drug resistance limits the success of many anticancer drugs. Reduced accumulation of the drug at its intracellular site of action because of overexpression of efflux transporters such as P-glycoprotein (P-gp) is a major mechanism of drug resistance. In this study, we investigated whether photodynamic therapy (PDT) using methylene blue, also a P-gp inhibitor, can be used to enhance doxorubicin-induced cytotoxicity in drug-resistant tumor cells. Aerosol OT (AOT)-alginate nanoparticles were used as a carrier for the simultaneous cellular delivery of doxorubicin and methylene blue. Methylene blue was photoactivated using light of 665 nm wavelength. Induction of apoptosis and necrosis following treatment with combination chemotherapy and PDT was investigated in drug-resistant NCI/ADR-RES cells using flow cytometry and fluorescence microscopy. Effect of encapsulation in nanoparticles on the intracellular accumulation of doxorubicin and methylene blue was investigated qualitatively using fluorescence microscopy and was quantitated using HPLC. Encapsulation in AOT-alginate nanoparticles significantly enhanced the cytotoxicity of combination therapy in resistant tumor cells. Nanoparticle-mediated combination therapy resulted in a significant induction of both apoptosis and necrosis. Improvement in cytotoxicity could be correlated with enhanced intracellular and nuclear delivery of the two drugs. Further, nanoparticle-mediated combination therapy resulted in significantly elevated reactive oxygen species (ROS) production compared to single drug treatment. In conclusion, nanoparticle-mediated combination chemotherapy and PDT using doxorubicin and methylene blue was able to overcome resistance mechanisms and resulted in improved cytotoxicity in drug-resistant tumor cells.

    Tuberculosis remains a worldwide problem, particularly with the advent of multi-drug resistance. Shortening therapy duration for Mycobacterium tuberculosis is a major goal, requiring generation of optimal kill rate and resistance-suppression. Combination therapy is required to attain the goal of shorter therapy. Our objective was to identify a method for identifying optimal combination chemotherapy. We developed a mathematical model for attaining this end. This is accomplished by identifying drug effect interaction (synergy, additivity, antagonism) for susceptible organisms and subpopulations resistant to each drug in the combination. We studied the combination of linezolid plus rifampin in our hollow fiber infection model. We generated a fully parametric drug effect interaction mathematical model. The results were subjected to Monte Carlo simulation to extend the findings to a population of patients by accounting for between-patient variability in drug pharmacokinetics. All monotherapy allowed emergence of resistance over the first two weeks of the experiment. In combination, the interaction was additive for each population (susceptible and resistant). For a 600 mg/600 mg daily regimen of linezolid plus rifampin, we demonstrated that >50% of simulated subjects had eradicated the susceptible population by day 27 with the remaining organisms resistant to one or the other drug. Only 4% of patients had complete organism eradication by experiment end. These data strongly suggest that in order to achieve the goal of shortening therapy, the original regimen may need to be changed at one month to a regimen of two completely new agents with resistance mechanisms independent of the initial regimen. This hypothesis which arose from the analysis is immediately testable in a clinical trial.

  13. Targeted Therapy of Cancer Using Photodynamic Therapy in Combination with Multi-faceted Anti-Tumor Modalities

    Full Text Available Photodynamic therapy (PDT has emerged as one of the important therapeutic options in the management of cancer and other diseases. PDT involves a tumor-localized photosensitizer (PS, which when appropriately illuminated by visible light converts oxygen into cytotoxic reactive oxygen species (ROS, that attack key structural entities within the targeted cells, ultimately resulting in necrosis or apoptosis. Though PDT is a selective modality, it can be further enhanced by combining other targeted therapeutic strategies that include the use of synthetic peptides and nanoparticles for selective delivery of photosensitizers. Another potentially promising strategy is the application of targeted therapeutics that exploit a myriad of critical pathways involved in tumorigenesis and metastasis. Vascular disrupting agents that eradicate tumor vasculature during PDT and anti-angiogenic agents that targets specific molecular pathways and prevent the formation of new blood vessels are novel therapeutic approaches that have been shown to improve treatment outcome. In addition to the well-documented mechanisms of direct cell killing and damage to the tumor vasculature, PDT can also activate the body’s immune response against tumors. Numerous pre-clinical studies and clinical observations have demonstrated the immuno-stimulatory capability of PDT. Herein, we aim to integrate the most important findings with regard to the combination of PDT and other novel targeted therapy approaches, detailing its potential in cancer photomedicine.

    Full Text Available Kenneth S Hershon1,2 1North Shore Diabetes and Endocrine Associates, New Hyde Park, 2Department of Medicine, Hofstra Northwell School of Medicine, Hempstead, NY, USA Objective: To update clinicians with an overview of empagliflozin for the treatment of type 2 diabetes mellitus (T2DM, with focus on use in combination regimens. Methods: Keyword searches were conducted in the Medline database to identify literature reporting clinical trials of at least 12 weeks' duration using empagliflozin treatment in patients with T2DM. Results: When given as monotherapy or in combination therapy (as add-on or single-pill therapy with metformin, pioglitazone, sulfonylurea, linagliptin, and insulin, empagliflozin produced clinically meaningful reductions in glycated hemoglobin levels, plasma glucose concentrations, bodyweight, and blood pressure. These changes were sustained during long-term treatment. In a dedicated cardiovascular event trial, empagliflozin on top of standard of care demonstrated a significant reduction in the risk of cardiovascular mortality and all-cause mortality. Across the clinical trials, empagliflozin combination therapies were well tolerated, and empagliflozin used alone was not associated with increased risk of hypoglycemia versus placebo. Indeed, the combination of empagliflozin and metformin had a significantly reduced rate of hypoglycemia compared with the combination of metformin and a sulfonylurea. On the other hand, empagliflozin treatment did have increased risk of genital infections compared with placebo. In clinical trials to date, diabetic ketoacidosis was not seen more frequently with empagliflozin than with placebo, but physicians should be alert to the possibility of this rare event. Conclusion: Empagliflozin has the potential to make an important contribution to the treatment of patients with T2DM. In some patients, empagliflozin may be used as monotherapy, but it is most likely to be used in combination with other

    Strategies in rheumatoid arthritis (RA) based on ‘treat to target’ aim to control disease activity, minimize structural damage, and promote longer life. Several disease-modifying antirheumatic drugs (DMARDs) have been shown to be effective including biological DMARDs (bDMARDs). Treatment guidelines and recommendations for RA have also been published. According to those guidelines, conventional synthetic DMARDs (csDMARDs), as monotherapy or combination therapy, should be used in DMARD-naïve patients, irrespective of the addition of glucocorticoids (GCs). Combination therapies with bDMARDs are also essential for conducting treatment strategies for RA, because in every recommendation or guideline for the management of RA, combination therapies of csDMARDs with bDMARDs are recommended for RA patients with moderate or high disease activity after failure of csDMARD treatment. bDMARDs are more efficacious if used concomitantly with methotrexate (MTX) than with MTX monotherapy or bDMARD monotherapy. Thus, retention has been reported to be longer when combined with MTX. The superior efficacy of combination therapy compared with MTX monotherapy or bDMARD monotherapy could be because: (1) it could help to minimize MTX toxicity by reducing the dose of MTX, thus retention rate of the same therapeutic regimen would become high; (2) anti-bDMARD antibodies are observed at lower concentrations when using MTX concomitantly, so less clearance of bDMARDs via less formation of bDMARD and an anti-bDMARD immune complex; (3) of the additive effects of MTX to bDMARD, especially the combination of tumor necrosis factor inhibitors (TNFis) with MTX. Hence, evidence suggests that combination therapy with bDMARDs is more efficacious than monotherapy using a csDMARD or bDMARD, and that MTX is the best drug for this purpose (if MTX is not contraindicated). Finding the most effective drug regimen at the lowest cost will be the aim of RA treatment in the future. PMID:27721905

    The history of stem cell gene therapy is strongly linked to the development of gene therapy for severe combined immunodeficiencies (SCID) and especially adenosine deaminase (ADA)-deficient SCID. Here we discuss the developments achieved in over two decades of clinical and laboratory research that led to the establishment of a protocol for the autologous transplant of retroviral vector-mediated gene-modified hematopoietic stem cells, which has proved to be both successful and, to date, safe. Patients in trials in three different countries have shown long-term immunological and metabolic correction. Nevertheless, improvements to the safety profile of viral vectors are underway and will undoubtedly reinforce the position of stem cell gene therapy as a treatment option for ADA-SCID. PMID:24198507

    Depressive disorders are common in children and adolescents and, if left untreated, are likely to recur in adulthood. Depression is highly debilitating, affecting psychosocial, family and academic functioning. To evaluate the effectiveness of psychological therapies and antidepressant medication, alone and in combination, for the treatment of depressive disorder in children and adolescents. We have examined clinical outcomes including remission, clinician and self reported depression measures, and suicide-related outcomes. We searched the Cochrane Depression, Anxiety and Neurosis Review Group's Specialised Register (CCDANCTR) to 11 June 2014. The register contains reports of relevant randomised controlled trials (RCTs) from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (1950 to date), EMBASE (1974 to date), and PsycINFO (1967 to date). RCTs were eligible for inclusion if they compared i) any psychological therapy with any antidepressant medication, or ii) a combination of psychological therapy and antidepressant medication with a psychological therapy alone, or an antidepressant medication alone, or iii) a combination of psychological therapy and antidepressant medication with a placebo or'treatment as usual', or (iv) a combination of psychological therapy and antidepressant medication with a psychological therapy or antidepressant medication plus a placebo.We included studies if they involved participants aged between 6 and 18 years, diagnosed by a clinician as having Major Depressive Disorder (MDD) based on Diagnostic and Statistical Manual (DSM) or International Classification of Diseases (ICD) criteria. Two review authors independently selected studies, extracted data and assessed the quality of the studies.

    Full Text Available Introduction: The aim of this study was to evaluate the efficacy of combined intratympanic and systemic steroid therapy compared with systemic steroid therapy alone in idiopathic sudden sensorineural hearing loss (ISSNHL patients with poor prognostic factors.     Materials and Methods: Seventy-seven patients with sudden sensorineural hearing loss (SSNHL who had at least one poor prognostic factor (age greater than 40 years, hearing loss more than 70 db, or greater than a 2-week delay between the onset of hearing loss and initiation of therapy were included in this study. Patients were randomized to the intervention group (combined intratympanic and systemic steroid therapy or the control group (systemic steroid therapy alone. All patients received oral treatment with systemic prednisolone (1 mg/kg/day for 10 days, acyclovir (2 g/day for 10 days, divided into four doses, triamterene H (daily, and omeprazole (daily, during steroid treatment, and were advised to follow a low salt diet. The intervention group also received intratympanic dexamethasone injections (0.4 ml of 4 mg/ml dexamethasone two times a week for two consecutive weeks (four injections in total. A significant hearing improvement was defined as at least a 15-db decrease in pure tone average (PTA.  Results: Among all participants, 44 patients (57.14% showed significant improvement in hearing evaluation. More patients showed hearing improvement in the intervention group than in the control group (27 patients (75% versus 17 patients (41.4%, respectively; P = 0.001.  Conclusion:  The combination of intratympanic dexamethasone and systemic prednisolone is more effective than systemic prednisolone alone in the treatment of poor-prognosis SSNHL.

    To test whether a combined intervention of art therapy and clown visits could enhance the efficacy of oral medication in reducing children's anxiety at parental separation prior to induction of anaesthesia. Approximately 50% of children undergoing surgery report high anxiety at anaesthesia induction. Complementary therapies have been used to decrease children's anxiety, but no study has evaluated the efficacy of a combination of such therapies. This is an observational study, which involved allocating different interventions to two groups and measuring their anxiety at two time points. This study assigned 78 children (aged 3-11 years) undergoing general anaesthesia for surgery to two conditions. The control group underwent general anaesthesia following standard practice, and the intervention group received an intervention of integrated art therapy and clown visits upon their arrival at the hospital and throughout their time in the preoperating room. Each child in both groups received 0·5 mg/kg oral midazolam 30 minutes before surgery and had a parent present throughout their time in the preoperating room. Each child's anxiety was evaluated twice using the Modified Yale Preoperative Anxiety Scale: at baseline and at separation from parents. Repeated measures anova was used to test for differences between the time points and the two groups. Children in the intervention group showed a significant (p art therapy and clown visits enhanced the effect of midazolam in reducing children's anxiety at preoperative separation from parents. Paediatric staffs may consider using such a combination of strategies in preparing children for anaesthesia induction. © 2016 John Wiley & Sons Ltd.

    The aim of the current research is to identify the clinical and microbiological effect of 5-nitroimidazol therapy for the treatment of bacterial vaginosis and in combination with probiotics and the influence of such therapy upon vaginal flora. Women (n = 539) with bacterial vaginosis who meet the criteria were included in the study. They were randomized into two groups with the following therapeutic regimes: in the first group (n = 242 women) the treatment included applications of 2g BID tinidazole for two days and vaginal suppositories of 1000 mg metronidazol at day 1 and 3 (T+M). In the second group (n = 297) the women were cured with the same treatment as those in the first group. In addition to it from the fifth day of the treatment was added a topical administration of vaginal probiotic which contains species of alive lactobacilli: Lactobacillus acidophilus, Lactobacillus rhamnosus (T+M+P). The efficacy from the therapy was evaluated using the clinical compliances of the women, the data from the clinical examination and the microbiological tests results. The results showed expected increase of clinical therapy efficacy (Amsel - criteria) from 42.8% (T+M; n = 211/242) to 84.06% (T+M+P; n = 274/297) in groups and of microbiological efficacy (Nugent) from 44.7% (T+M; n = 211/242) to 83.3% (T+M+P; n = 274/297), in follow up 35-40 days from the beginning of treatment. The percentage of women with normal vaginal flora on 35-40 day after the therapy increase with 57% in the (T+M) first group while in the second group (T+M+P) with 94%. Combining the therapies of 5-nitroimidazoles and vaginal probiotic reduce bacterial vaginosis recurrence and restores permanently normal vaginal flora.

    We aimed to examine the effectiveness of combined neurofeedback therapy and imagery training in adolescent patients with refractory Tourette syndrome. Two patients, aged respectively 14 and 16 years, had been treated with haloperidol and tiapride; however, this medication was ineffective and accompanied by intolerable side effects. In this study, the patients completed 80 sessions of neurofeedback treatment followed by imagery training. The patients were assessed with behavior rating scales both before and after the treatment as well as during follow-up examinations to evaluate the effect of the combined therapy. Patients showed significant improvement in motor tic and vocal tic symptoms, exemplified by a reduction in the frequency and intensity of tics, indicating that neurofeedback, together with imagery training, has a positive therapeutic effect on adolescent patients with medication-refractory Tourette syndrome.

    Psoriasis is an autoimmune, chronic, inflammatory skin disease characterized by epidermal hyperplasia, proliferation of blood vessels, and infiltration of leukocytes in dermis and epidermis. Several immunosuppressants such as methotrexate (MXT) and cyclosporine are used but they are associated with adverse effects due to down regulation of immune system. Numerous approaches have been explored to overcome the problems of conventional topical system such as high frequency of application, impermeability to skin barrier, and limited efficacy. Photodynamic therapy is another non-invasive technique currently used for skin diseases. The combination of two drugs is also commonly observed to achieve more effective therapy. In the present study, antipsoriatic activity of niosomal formulations for the treatment of psoriasis in combination with narrow and broad band UV radiation had been explored in experimental animal model.

Here we discuss the developments achieved in over two decades of clinical and laboratory research that led to the establishment of a protocol for the autologous transplant of retroviral vector-mediated gene-modified hematopoietic stem cells, which has proved to be both successful and, to date, safe. Patients in trials in three different countries have shown long-term immunological and metabolic correction. Nevertheless, improvements to the safety profile of viral vectors are underway and will undoubtedly reinforce the position of stem cell gene therapy as a treatment option for ADA-SCID.Keywords: adenosine deaminase, severe combined immunodeficiency, gene therapy, hematopoietic stem cell, retrovirus, clinical trial

    One of the important problems of modern medicine is treatment of infected wounds. There are many diversified expedients of treatment, but none of them obey the modern physician completely. The aim of this study is to develop and test a new combined method of photodynamic ultrasonic therapy (PDUST) for treatment of infected wounds with focus on experimental trials. PDUST is based on a combination of two methods: photodynamic (PD) therapy (PDT) with photosensitizer and low frequency ultrasonic (US) therapy with antibiotic as tools for treatment of wounds and effectively killing bacteria. The main parameters are: US frequency - 26.5 kHz; US tip elongation - 40+/-20 μm wavelength of light emitting diodes (LED) array - 660+/-10 nm; light intensity on biotissue surface - 1-2 mW/cm2; photosensitizer - an aluminum disulfonated phtalocyanine dissolved in a physiological solution in concentration 10 mg/l. The experiments were carried out with 70 male chinchilla rabbits divided into 7 groups, thus the dynamics of wounds healing were studied in different modes of PDUST. The PD and US methods supplement each other and in conjunction provide additive and especially synergetic effects. The experimental data demonstrated advantages of new technology in comparison with conventional methods in cases of treatment of extended suppurative inflammatory and profound wounds. The more detailed study of PDUST method's mechanism, which is based on low intensity of LED light, PD therapy and US influence is required.

    The aims of this study were to evaluate the effectiveness of the Fear Hunter cognitive behavioral therapy program, which was developed for the treatment of childhood anxiety disorders, and to compare its effectiveness with standard medication treatment. A total of 46 participants (aged 8 to 12) that applied to the Ege University, Faculty of Medicine, Child and Adolescent Psychiatry clinic and had a diagnosis of anxiety disorder were recruited for the study. The participants were randomly assigned to cognitive behavioral therapy (CBT), standard drug treatment (ST), or combined treatment (CBT+ ST) groups according to the order of application. Subjects were evaluated using pretest, posttest and 3 months follow-up measurements. The participants were assessed by the researcher using The Screen for Child Anxiety Related Emotional Disorders (SCARED), The Children's Negative Cognitive Errors Questionnaire (CNCEQ), Health Related Quality of Life in Children (Kid-KINDL), and Children's Depression Inventory (CDI). The results of repeated measures ANOVA showed that, although general anxiety scores of all treatment conditions significantly decreased at posttest and follow up, a combination of two therapies (CBT+ST) had a significantly superior response rate. Moreover, all treatment conditions including CBT (CBT+ST and CBT) were superior to ST in terms of negative cognitive errors, quality of life, and depression. It is thought that The Fear Hunter Therapy Program is an effective treatment technique because; it provides significant improvement in the primary and secondary symptoms (e.g. quality of life, depression, negative automatic thoughts) of childhood anxiety disorders.

    Full Text Available Background: Childhood vitiligo is always a challenge to treat, especially when the disease is progressing rapidly in such a patient. Oral minipulse with betamethasone has been tried in childhood vitiligo and also in some other immune mediated skin disorders with good results. Aims: The aim of the present study was to see the overall efficacy of methylprednisolone oral minipulse therapy in combination with topical fluticasone in progressive childhood vitiligo. The combination was tried to achieve a significant amount of repigmentation of vitiligo lesions already present at the initial visit. Materials and Methods: Four hundred children with progressive vitiligo were enrolled for this study and were prescribed oral methylprednisolone on two consecutive days every week in a minipulse form for a period of six months. In addition, the patients were instructed to apply fluticasone ointment topically once a day on their vitiligo lesions. The patients were assessed for the remission achieved as well as the extent of repigmentation of their already existent lesions. Results: More than 90% of patients went into complete remission after the start of the therapy. Moreover, about 65% (two-thirds of patients achieved good to excellent repigmentation of lesions at the end of six months of therapy. The therapy was also well tolerated and the side effects seen were almost negligible. Conclusions: Oral minipulse treatment with methylprednisolone is an effective treatment option for controlling the disease spread in childhood vitiligo and with the addition of topical fluticasone the extent of repigmentation achieved is also quite significant.

    Full Text Available Studies have shown that topical 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT can be used successfully for the treatment of oral verrucous hyperplasia (OVH. Studies have also demonstrated that cryotherapy could be used as a treatment modality for OVH lesions. In this case report, we tested the efficacy of topical ALA-PDT, combined with cryogun cryotherapy, for an extensive OVH lesion on the right buccal mucosa of a 65-year-old male areca quid chewer. The tumor was cleared after six treatments of combined topical ALA-PDT and cryogun cryotherapy. No recurrence of the lesion was found after a follow-up period of 18 months. We suggest that our combined treatment protocol may be effective in treating OVH lesions. The treatment course may be slightly shortened with this combined protocol and was well tolerated by the patient.

    In this paper, we argue that circulating metaphors and beliefs can create an environment in which particular biomedical treatments make cultural sense, even if they seem to be ineffective or are associated with unpleasant side effects. We develop this argument in relation to interferon combined therapy. An innovative methodology combining the collection and deconstructive analysis of visual and narrative texts produced by people with hepatitis C is used to demonstrate links between a predisposition towards Western biomedical practice, discomfort with uncertainty, a desire to reassert control, and adoption of conflict metaphors associated with the tropes of invasion and eradication.

However, the usefulness of combination therapy with a selective neutrophil elastase inhibitor, sivelestat, and recombinant human soluble thrombomodulin (rhTM for patients with ARDS and DIC remains unknown. Methods: We conducted a retrospective data analysis of 142 ARDS patients with DIC to assess the effects of sivelestat combined with rhTM. Patients were divided into four groups: control (no sivelestat or rhTM treatment, sivelestat treatment alone, rhTM treatment alone, and combined treatment with sivelestat and rhTM. A Cox proportional hazard model was used to assess subject mortality rates. The efficacy of these drugs was evaluated based on survival rate, number of ventilator-free days, and change in PaO2/FIO2 (P/F ratios and DIC scores before and at 7 days after a diagnosis of ARDS with DIC. Results: Multivariate analysis showed that patient age, combination therapy, gas exchange, organ failure, cause, associated disease score, and serum C-reactive protein levels were predictors of mortality for patients with ARDS and DIC. As compared with untreated controls, combination therapy significantly improved the 60-day survival rate of patients with ARDS and DIC

    Type 2 diabetes is characterized by an insulin secretory defect that cannot compensate for insulin resistance. Such relative defect is present in the fasting state (insufficient basal insulin levels) and contributes to overnight hyperglycaemia; it is even more pronounced in the postprandial state when it is then the main responsible factor for hyperglycaemia following meals. An original approach to correct these two disturbances is to propose a therapy combining the injection of a basal insul...

    We analyzed the effect of combination therapy on seizure frequency in all adult patients (N=193) with focal epilepsy followed at a single institution in a cross-sectional study. One hundred and thirty-five patients were on two AEDs, of them, 37 (27%) were seizure-free, 50 patients were on three AEDs including 5 (10%) seizure-free patients (pseizure-freedom with two AEDs versus three AEDs). Thirty-five different combinations were used in patients on two AEDs and 40 combinations on patients on three drugs emphasizing the difficulties involved in evaluation of the efficacy and tolerability of specific combinations. The significant proportion of seizure-free cases (27%) on duotherapy is suggesting the usefulness of combination therapy in achieving seizure-freedom in epilepsies refractory to single drug treatment. The material in the study was not from a randomized trial and therefore the comparability of patients on different AEDs is uncertain, but on the other hand the clinical practice followed provides a natural experiment suitable for comparative, non-randomized assessment of treatment outcomes.

    Full Text Available Ceramide (CE-based combination therapy (CE combination as a novel therapeutic strategy has attracted great attention in the field of anti-cancer therapy. The principal purposes of this study were to investigate the synergistic effect of CE in combination with docetaxel (DTX (CE + DTX and to explore the synergy mechanisms of CE + DTX. The 3-(4,5-Dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide (MTT and combination index (CI assay showed that simultaneous administration of CE and DTX with a molar ratio of 0.5:1 could generate the optimal synergistic effect on murine malignant melanoma cell (B16, CI = 0.31 and human breast carcinoma cell (MCF-7, CI = 0.48. The apoptosis, cell cycle, and cytoskeleton destruction study demonstrated that CE could target and destruct the microfilament actin, subsequently activate Caspase-3 and induce apoptosis. Meanwhile, DTX could target and disrupt the microtubules cytoskeleton, leading to a high proportion of cancer cells in G2/M-phase arrest. Moreover, CE plus DTX could cause a synergistic destruction of cytoskeleton, which resulted in a significantly higher apoptosis and a significantly higher arrest in G2/M arrest comparing with either agent alone (p < 0.01. The in vivo antitumor study evaluated in B16 tumor-bearing mice also validated the synergistic effects. All these results suggested that CE could enhance the antitumor activity of DTX in a synergistic manner, which suggest promising application prospects of CE + DTX combination treatment.

    Despite expansion of the antifungal armamentarium over the past decade, the mortality rate for invasive fungal infections remains high in severely immunocompromised patients. Furthermore, in recent years, difficult-to-treat invasive infections caused by rare molds and yeasts have emerged in high-risk patients receiving antifungal prophylaxis or empirical treatment. Antifungal combinations are increasingly used in clinical practice to improve outcomes for refractory mycoses because of the suboptimal efficacy of current antifungal agents. Herein we review recent advances in the area of antifungal combinations in high-risk patients to separate empiricism from evidence-based medicine. Thus far, the benefits of combination antifungal therapy have been difficult to prove for invasive fungal infections other than cryptococcal meningitis. The recent introduction of a new class of antifungal agents (the echinocandins) and extended-spectrum triazoles has rejuvenated interest in studying those combinations for difficult-to-treat aspergillosis, as recent observational studies show promise. In view of the evolving epidemiology of invasive fungal infections, combination antifungal therapy could be most valuable in preemptive management of carefully selected high-risk patients; however, this should be studied in appropriate trials.

Unfortunately, most patients require multiple medications to obtain glycemic control. One of the newest additions to the antidiabetic armamentarium is the class of drugs known as dipeptidyl-peptidase IV (DPP-IV inhibitors. This novel approach focuses on harnessing the beneficial effects of GLP-1, an incretin hormone released from the gut postprandially. The first DPP-IV inhibitor approved in the United States was sitagliptin. It has been studied in both monotherapy and combination therapy. Combination studies with metformin realize a hemoglobin A1c reduction of 0.65%–1.1%. The combination of the two has a modest positive effect on body weight with the convenience of an oral route of administration. It has also been shown to be highly tolerable, efficacious and with little risk of hypoglycemia. This review will focus on combination therapy with sitagliptin with emphasis on combination with metformin. Keywords: DPP-IV inhibitor, sitagliptin, metformin, type 2 diabetes, incretins

    Full Text Available OBJECTIVES: The purpose is to study the effects of hyperbaric oxygen therapy and autologous platelet concentrates in healing the fibula bone of rabbits after induced fractures. METHODS: A total of 128 male New Zealand albino rabbits, between 6-8 months old, were subjected to a total osteotomy of the proximal portion of the right fibula. After surgery, the animals were divided into four groups (n = 32 each: control group, in which animals were subjected to osteotomy; autologous platelet concentrate group, in which animals were subjected to osteotomy and autologous platelet concentrate applied at the fracture site; hyperbaric oxygen group, in which animals were subjected to osteotomy and 9 consecutive daily hyperbaric oxygen therapy sessions; and autologous platelet concentrate and hyperbaric oxygen group, in which animals were subjected to osteotomy, autologous platelet concentrate applied at the fracture site, and 9 consecutive daily hyperbaric oxygen therapy sessions. Each group was divided into 4 subgroups according to a pre-determined euthanasia time points: 2, 4, 6, and 8 weeks postoperative. After euthanasia at a specific time point, the fibula containing the osseous callus was prepared histologically and stained with hematoxylin and eosin or picrosirius red. RESULTS: Autologous platelet concentrates and hyperbaric oxygen therapy, applied together or separately, increased the rate of bone healing compared with the control group. CONCLUSION: Hyperbaric oxygen therapy and autologous platelet concentrate combined increased the rate of bone healing in this experimental model.

    In 2003, the program "The combined DAK therapy of obesity for children and adolescents", funded and conducted by the Deutsche Angestellten Krankenkasse (DAK) (A German Health Insurance Company), has started. The whole treatment lasts for 1 year including an initial inpatient therapy for 6 weeks followed by an outpatient treatment at home that adresses the overweight patients and their families. The therapy contents are developed according to the recommendations of the "Arbeitsgemeinschaft Adipositas im Kindes- und Jugendalter (AGA)". In a prospective cohort study a sample of 604 subjects was studied in order to examine the achievement of the treatment goals weight reduction, behaviour modification and improvement of quality of life. The development of weight was evaluated using BMI-SDS. 44,1% of children and adolescents had a successful weight reduction, they reduced their weight at least by 0,3 BMI-SDS. Furthermore, significant changes of health behaviour, physical fitness and quality of life were observed. However, during the outpatient treatment an impairment of some behaviour changes were observed. Nevertheless, the study has identified significant, positive effects in weight loss, behaviour modifications, changes in physical fitness and in the development of quality of life as a result of the therapy. It is demonstrated that a relapse in "old behaviour" followed by an increase of weight after the inpatient treatment can be avoided bythe subsequent outpatient therapy.

    We managed 6 cases of severe liver atrophy and failure associated with paclitaxel and bevacizumab combination therapy (PB therapy)for HER2-negative metastatic breast cancer. In this case-controlstudy, we examined the records of these 6 patients to investigate past treatment, medication history, and degree of atrophy, and compared their data with that of 67 patients without liver atrophy. The degree of the liver atrophy used SYNAPSE VINCENT®of the image analysis software. The results showed that patients with liver atrophy had a longer pretreatment period than those without liver atrophy(33.5 months vs 15.5 months), and they also experienced a longer median time to treatment failure with PB therapy than other patients(11 months vs 6 months). The ratio of individuals presenting with diffuse liver metastasis among patients with liver metastasis was 80% with liver atrophy, compared to 8% without liver atrophy. The degree of liver atrophy was an average of 67%in terms of volume ratio before/after PB therapy(57-82%). The individualwith the greatest extent of liver atrophy died of liver failure, not as a result of breast cancer progression. The direct causal link between bevacizumab and liver atrophy and failure is unclear, but the individuals in this study had a long previous history of treatment, and diffuse liver metastases may develop in patients undergoing long periods of PB therapy, which may also cause liver atrophy; therefore, the possibility of liver failure should be considered in such cases.

    Full Text Available Carlos M Ferrario, Ronald D SmithWake Forest University School of Medicine, Winston-Salem, North Carolina, USAAbstract: Angiotensin receptor blockers have emerged as a first-line therapy in the management of hypertension and hypertension-related comorbidities. Since national and international guidelines have stressed the need to control blood pressure to <140/90 mmHg in uncomplicated hypertension and <130/80 mmHg in those with associated comorbidities such as diabetes or chronic kidney disease, these goal blood pressures can only be achieved through combination therapy. Of several drugs that can be effectively combined to attain the recommended blood pressure goals, fixed-dose combinations of angiotensin receptor blockers and the calcium channel blocker amlodipine provide additive antihypertensive effects associated with a safe profile and increased adherence to therapy. In this article, we review the evidence regarding the beneficial effects of renin–angiotensin system blockade with olmesartan medoxomil and amlodipine in terms of blood pressure control and improvement of vascular function and target organ damage.Keywords: amlodipine, angiotensin receptor blockers, angiotensin-converting enzyme 2, hypertension, renin–angiotensin system

    In spite of the advances in drug delivery, the preparation of smart nanocomposites capable of precisely controlled release of multiple drugs for sequential combination therapy is still challenging. Here, a novel drug delivery nanocomposite was prepared by coating porous silicon (PSi) nanoparticles with poly(beta-amino ester) (PAE) and Pluronic F-127, respectively. Two anticancer drugs, doxorubicin (DOX) and paclitaxel (PTX), were separately loaded into the core of PSi and the shell of F127. The nanocomposite displayed enhanced colloidal stability and good cytocompatibility. Moreover, a spatiotemporal drug release was achieved for sequential combination therapy by precisely controlling the release kinetics of the two tested drugs. The release of PTX and DOX occurred in a time-staggered manner; PTX was released much faster and earlier than DOX at pH 7.0. The grafted PAE on the external surface of PSi acted as a pH-responsive nanovalve for the site-specific release of DOX. In vitro cytotoxicity tests demonstrated that the DOX and PTX coloaded nanoparticles exhibited a better synergistic effect than the free drugs in inducing cellular apoptosis. Therefore, the present study demonstrates a promising strategy to enhance the efficiency of combination cancer therapies by precisely controlling the release kinetics of different drugs.

  20. Combination therapies: The next logical Step for the treatment of synucleinopathies?

    Valera, Elvira; Masliah, Eliezer

    2016-02-01

    Currently there are no disease-modifying alternatives for the treatment of most neurodegenerative disorders. The available therapies for diseases such as Parkinson's disease (PD), PD dementia (PDD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA), in which the protein alpha-synuclein (α-Syn) accumulates within neurons and glial cells with toxic consequences, are focused on managing the disease symptoms. However, using strategic drug combinations and/or multi-target drugs might increase the treatment efficiency when compared with monotherapies. Synucleinopathies are complex disorders that progress through several stages, and toxic α-Syn aggregates exhibit prion-like behavior spreading from cell to cell. Therefore, it follows that these neurodegenerative disorders might require equally complex therapeutic approaches to obtain significant and long-lasting results. Hypothetically, therapies aimed at reducing α-Syn accumulation and cell-to-cell transfer, such as immunotherapy against α-Syn, could be combined with agents that reduce neuroinflammation with potential synergistic outcomes. Here we review the current evidence supporting this type of approach, suggesting that such rational therapy combinations, together with the use of multi-target drugs, may hold promise as the next logical step for the treatment of synucleinopathies.

    An estimated 300 million people worldwide suffer fromchronic hepatitis C with a prevalence of 0.8%-1.0% of the general population in Canada. An increasing pool of evidence exists supporting the use of pegylatedinterferon (pegIFN) and ribavirin combination therapy for hepatitis C. We report a 49-year old male of North American aboriginal descent with chronic hepatitis C (genotype 2b). Biopsy confirmed that he had cirrhosis with a 2-wk history of left eye pain and decreased visual acuity. He developed retinal vein thrombosis after 16 of 24 wk of pegIFN-α 2a and ribavirin combination therapy. He was urgently referred to a retinal specialist and diagnosed with non-ischemic central retinal vein occlusion of the left eye. PegIFN and ribavirin combination therapy was discontinued and HCV RNA was undetectable after 16 wk of treatment. Hematologic investigations revealed that the patient was a factor V Leiden heterozygote with mildly decreased protein C activity. Our patient had a number of hypercoagulable risk factors, including factor V Leiden heterozygosity, cirrhosis, and hepatitis C that alone would have most likely remained clinically silent. We speculate that in the setting of pegIFN treatment, these risk factors may coalesce and cause the retinal vein thrombosis.

    BACKGROUND The outcomes of gene therapy to correct congenital immunodeficiencies are unknown. We reviewed long-term outcomes after gene therapy in nine patients with X-linked severe combined immunodeficiency (SCID-X1), which is characterized by the absence of the cytokine receptor common γ chain. METHODS The nine patients, who lacked an HLA-identical donor, underwent ex vivo retrovirus-mediated transfer of γ chain to autologous CD34+ bone marrow cells between 1999 and 2002. We assessed clinical events and immune function on long-term follow-up. RESULTS Eight patients were alive after a median follow-up period of 9 years (range, 8 to 11). Gene therapy was initially successful at correcting immune dysfunction in eight of the nine patients. However, acute leukemia developed in four patients, and one died. Transduced T cells were detected for up to 10.7 years after gene therapy. Seven patients, including the three survivors of leukemia, had sustained immune reconstitution; three patients required immunoglobulin-replacement therapy. Sustained thymopoiesis was established by the persistent presence of naive T cells, even after chemotherapy in three patients. The T-cell–receptor repertoire was diverse in all patients. Transduced B cells were not detected. Correction of the immunodeficiency improved the patients’ health. CONCLUSIONS After nearly 10 years of follow-up, gene therapy was shown to have corrected the immunodeficiency associated with SCID-X1. Gene therapy may be an option for patients who do not have an HLA-identical donor for hematopoietic stem-cell transplantation and for whom the risks are deemed acceptable. This treatment is associated with a risk of acute leukemia. (Funded by INSERM and others.) PMID:20660403

    Full Text Available Kazuya Horiuchi, Keita Kasahara, Yusuke Kuroda, Haruna Morohoshi, Yosuke Hagiwara, Gen Ishii Respiratory Disease Center, Showa University Northern Yokohama Hospital, Yokohama-shi, Kanagawa-ken, Japan Purpose: A combination therapy with inhaled corticosteroid (ICS and a long-acting β agonist (LABA is the standard treatment for asthmatic patients, and step-down treatment is recommended once control has been achieved. However, little data exist that evaluate the long-term outcomes after step-down treatment. Objective: To compare the long-term outcomes of step-down therapy with ICS/LABA or ICS alone for asthmatic patients who have achieved well-controlled asthma by the ICS (250 µg fluticasone/LABA (50 µg salmeterol combination (SFC, two puffs per day. Patients and methods: We randomized 40 well-controlled patients with asthma receiving SFC (250 µg to two groups; one group of patients received step-down therapy with low-dose SFC (100 µg, two puffs daily and another group of patients received step-down therapy with high-dose fluticasone propionate (FP alone (500 µg, daily. The two groups were monitored over 12 months for changes in asthma control test scores, respiratory function (percent forced expiratory volume in 1 second, maximal expiratory flow rate at 50% of the vital capacity [%FEF50], and maximal expiratory flow rate at 25% of the vital capacity [%FEF25], and the concentration of fractional exhaled nitric oxide. Results: There was no significant difference in the dropout rate between the SFC and FP groups. Low-dose SFC maintained the stability of all parameters over 12 months, whereas the FP group exhibited a rapid 5% decrease in forced expiratory volume in 1 second within 2 months after discontinuation of salmeterol; furthermore, after 10 months, there was a gradual decrease in %FEF50 and %FEF25. Conclusion: This study suggests that a balanced step-down protocol, including both ICS and LABA, is essential in providing long-term stability

    Full Text Available BACKGROUND AND AIM: A large number of studies have tried to combine sorafenib with TACE for patients with unresectable hepatocellular carcinoma (HCC and the results were controversial. We conducted this systematic review and meta-analysis to evaluate the safety and efficacy of combination therapy of sorafenib and TACE in the management of unresectable HCC. METHODS: MEDLINE, PsycINFO, Scopus, EMBASE, and the Cochrane Library were searched from January 1990 to October 2013 and these databases were searched for appropriate studies combining TACE and sorafenib in treatment of HCC. Two authors independently reviewed the databases and extracted the data and disagreements were resolved by discussion. Effective value and safety were analyzed. Effective value included disease control rate (DCR, time to progression (TTP and overall survival (OS. RESULTS: 17 studies were included in the study. In the 10 noncomparative studies, DCR ranged from 18.4 to 91.2%. Median TTP ranged from 7.1 to 9.0 months, and median OS ranged from 12 to 27 months. In the 7 comparative studies, the hazard ratio (HR for TTP was found to be 0.76 (95% CI 0.66-0.89; P<0.001 with low heterogeneity among studies (P = 0.243; I(2 = 25.5%. However, the HR for OS was found to be 0.81 (95% CI 0.65-1.01; P = 0.061 with low heterogeneity among studies (P = 0.259; I(2 = 25.4%. The common toxicities included fatigue, diarrhea, nausea, hand foot skin reaction (HFSR, hematological events, hepatotoxicity, alopecia, hepatotoxicity, hypertension and rash/desquamation. AEs are generally manageable with dose reductions. CONCLUSIONS: Combination therapy may bring benefits for unresectable HCC patients in terms of TTP but not OS. Further well-designed randomized controlled studies are needed to confirm the efficacy of combination therapy.

    Telmisartan suppresses the development of endometriotic lesions. However, the drug also up-regulates the expression of COX-2, which has been suggested to promote the progression of endometriosis. Accordingly, in the present study we analysed whether a combination therapy with telmisartan and a COX-2 inhibitor may be more effective in the treatment of endometriotic lesions than the application of telmisartan alone. Endometriotic lesions were induced in the peritoneal cavity of C57BL/6 mice, which were treated daily with an i.p. injection of telmisartan (10 mg·kg(-1) ), parecoxib (5 mg·kg(-1) ), a combination of telmisartan and parecoxib or vehicle. Therapeutic effects on lesion survival, growth, vascularization, innervation and protein expression were studied over 4 weeks by high-resolution ultrasound imaging as well as immunohistochemical and Western blot analyses. Telmisartan-treated lesions exhibited a significantly reduced lesion volume when compared with vehicle-treated controls and parecoxib-treated lesions. This inhibitory effect of telmisartan was even more pronounced when it was used in combination with parecoxib. The combination therapy resulted in a reduced microvessel density as well as lower numbers of proliferating Ki67-positive cells and higher numbers of apoptotic cleaved caspase-3-positive stromal cells within the lesions. This was associated with a lower expression of COX-2, MMP-9 and p-Akt/Akt when compared with controls. The application of the two drugs further inhibited the ingrowth of nerve fibres into the lesions. Combination therapy with telmisartan and a COX-2 inhibitor represents a novel, effective pharmacological strategy for the treatment of endometriosis. © 2017 The British Pharmacological Society.

    Full Text Available Introduction: The pathophysiology of type 2 diabetes (T2DM mainly focused on insulin resistance and insulin deficiency over the past decades. Currently, the pathophysiologies expanded to ominous octet and guidelines were updated with newer generation of antidiabetic drug classes. However, many patients had yet to achieve their target glycaemic control. Although all the guidelines suggested metformin as first line, there was no definite consensus on the second line drug agents as variety of drug classes were recommended. Objectives: The aim of this review was to evaluate the drug class after metformin especially sulphonylurea and issues around add-on or fixed dose combination therapy. Methods: Extensive literature search for English language articles, clinical practice guidelines and references was performed using electronic databases. Results: Adding sulphonylurea to metformin targeted both insulin resistance and insulin deficiency. Sulphonylurea was efficacious and cheaper than thiazolidinedione, dipeptidyl peptidase-4 inhibitor, glucagon-like peptide 1 analogue and insulin. The main side effect of sulphonylurea was hypoglycaemia but there was no effect on the body weight when combining with metformin. Fixed dose sulphonylurea/metformin was more efficacious at lower dose and reported to have fewer side effects with better adherence. Furthermore, fixed dose combination was cheaper than add-on therapy. In conclusion, sulphonylurea was feasible as the second line agent after metformin as the combination targeted on two pathways, efficacious, cost-effective and had long safety history. Fixed dose combination tablet could improve patient’s adherence and offered an inexpensive and more efficacious option regardless of original or generic product as compared to add-on therapy.

    Iron overload is the main cause of morbidity and mortality especially from heart failure in patients with beta thalassemia major (TM). Successful iron chelation is therefore essential for the optimal management of TM. Although desferrioxamine (DFX) has been the major iron-chelating treatment of transfusional iron overload, compliance is a major hindrance in achieving optimal therapeutic results. The availability of oral iron chelation with deferiprone (L(1)) since 1987 is useful but showed poor efficacy when used alone as compared to DFX. We therefore decided to compare DFX alone with a prospective combined therapy with DFX and L(1) in beta thalassemia major patients with iron overload. We studied 91 patients with beta thalassemia major (mean age+/-SD, 15.02+/-5.8; range 2-30 years) attending the day care unit for regular transfusional support. They received packed red cells every 3-4 weeks to maintain pretransfusion hemoglobin concentration above 9 g/dl. They had been receiving DFX at a daily dose of 40 mg kg(-1) day(-1) by subcutaneous infusion for 8-10 h on 4-5 nights each week for the past several years. However, due to various reasons, they had developed considerable transfusional iron overload. These patients were allocated to prospectively receive additional therapy with oral iron chelator L(1) at 75 mg kg(-1) day(-1) body weight in three divided doses with food after informed consent and continued to receive treatment with DFX as per the above dosage. Of the 91 patients, six developed severe gastrointestinal (GI) upset, two agranulocytosis, two arthropathy, one persistently raised liver enzymes, two died owing to sepsis, and two received allogeneic bone marrow transplantation. Amongst the remaining 76 patients, 21 were found noncompliant (not taking DFX regularly, but taking L(1) regularly). Thus, in the 55 evaluable patients {6-48 months on combination therapy; mean [(+/-SD)22+/-12 months]}, the mean serum ferritin (+/-SD) fell dramatically from 3

    Full Text Available Abstract Background Combinations of disease-modifying anti-rheumatic drugs (DMARDs are increasingly used to control active rheumatoid arthritis (RA; however there is little information about patients’ perspectives, their expectations, concerns and experiences of this intensive treatment. Method We interviewed a quota sample of 18 patients from a single tertiary outpatient clinic, stratified by gender, ethnicity and age, based on the outpatient clinic population. Patients with early RA (2 years received combined conventional DMARDs or DMARDs with biologics. Results Four main themes emerged from the analytical framework: (i patients’ expectations about the combined treatment focuses mainly on physical symptoms; (ii the impact of the treatment on quality of life varied with the new medication in both groups (iii concerns about new interventions concentrated mainly on potential side effects; and (iv combination therapy can be self-managed in close collaboration with clinic staff, but this requires individualised management approaches. These themes resonate with von Korff’s collaborative management of chronic illness model. Conclusion To our knowledge this is the first qualitative study that examined systematically in patients with early and established RA their expectations, impact on quality of life, concerns about side effects and the management of the treatment when taking combined medication with DMARDs or DMARDs and biologics. Patients have generally positive views of combination DMARDs. Within routine practice settings, achieving medication concordance with complex combined DMARD regimens is challenging, and the concerns vary between patients; careful individual assessments are essential to successfully deliver such intensive treatment.

    As the immunotherapy of cancer comes of age, adding immunotherapeutic agents to radiation therapy has the potential to improve the outcomes for patients with a wide variety of malignancies. Despite the enormous potential of such combination therapy, laboratory data has been lacking and there is little guidance for pursuing novel treatment strategies. Animal models have significant limitation in combining radiation therapy with immunotherapy and some of the limitations of preclinical models are discussed in this article. In addition to the preclinical challenges, radiation therapy and immunotherapy combinations may have overlapping toxicities, and for both types of therapy, early and late manifestations of toxicity are possible. Given these risks, special attention should be given to the design of the specific Phase I clinical trial that is chosen. In this article, we describe several Phase I design possibilities that may be employed, including the 3 + 3 design (also known as the cohort of 3 design), the continual reassessment method (CRM), and the time-to-event continual reassessment method (TITE-CRM). Efficacy end points for further development of combination therapy must be based on multiple factors, including disease type, stage of disease, the setting of therapy and the goal of therapy. While the designs for future clinical trials will vary, it is clear that these two successful modalities of therapy can and should be combined for the benefit of cancer patients.

    Full Text Available Abstract Objective Determine the long-term effectiveness of quetiapine in combination with standard treatments in preventing relapses for patients with bipolar I disorders Method Twenty-one outpatients with type I bipolar disorder who had inadequate responses to ongoing standard therapies were treated with add-on quetiapine in an open-label study. The quetiapine dose was increased until clinical response occurred. Illness response was assessed using the Clinical Global Impression (CGI scale. Relapse rates before and during quetiapine treatment were compared by calculating incidence risk ratios. Results Quetiapine was added to ongoing standard therapy for 26 to 78 weeks. Thirteen patients received combination therapy for at least 52 weeks. The mean quetiapine dose received was 518 ± 244 mg/day. There were highly significant improvements in overall relapse rate, manic/mixed relapse rate, and depression relapse rate in the period during quetiapine treatment compared with the period before quetiapine was initiated. The calculated relative risk of relapse in the absence of quetiapine treatment was 2.9 overall (95% confidence interval, 1.5~5.6, 3.3 for manic/mixed relapse (95% confidence interval, 1.5~7.1, and 2.4 for depressive relapse (95% confidence interval, 1.3~4.4. The mean Clinical Global Impression scores improved significantly from baseline during 26 weeks of quetiapine treatment in 21 patients (p = 0.002 and remained significantly better during a 52-week treatment period in 13 patients (p = 0.036. Conclusion Long-term treatment with quetiapine combination therapy reduced the probability of manic/mixed and depressive relapses and improved symptoms in patients with bipolar I disorder who had inadequate responses to ongoing standard treatment.

    Recently, microRNA (miRNA or miR) has emerged as a new cancer biomarker because of its high expression level in various cancer types and its role in the control of tumor suppressor genes. In cancer studies, molecular imaging and treatment based on target cancer markers have been combined to facilitate simultaneous cancer diagnosis and therapy. In this study, for combined therapy with diagnosis of cancer, we developed a doxorubicin-conjugated miR-221 molecular beacon (miR-221 DOXO MB) in a single platform composed of three different nucleotides: miR-221 binding sequence, black hole quencher 1 (BHQ1), and doxorubicin binding site. Imaging of endogenous miR-221 was achieved by specific hybridization between miR-221 and the miR-221 binding site in miR-221 DOXO MB. The presence of miR-221 triggered detachment of the quencher oligo and subsequent activation of a fluorescent signal of miR-221 DOXO MB. Simultaneous cancer therapy in C6 astrocytoma cells and nude mice was achieved by inhibition of miRNA-221 function that downregulates tumor suppressor genes. The detection of miR-221 expression and inhibition of miR-221 function by miR-221 DOXO MB provide the feasibility as a cancer theragnostic probe. Furthermore, a cytotoxic effect was induced by unloading of doxorubicin intercalated into miR-221 DOXO MB inside cells. Loss of miR-221 function and cytotoxicity induced by the miR-221 DOXO MB provides combined therapeutic efficacy against cancers. This method could be used as a new theragnostic probe with enhanced therapy to detect and inhibit many cancer-related miRNAs.

    Chemo-photodynamic combination therapy has been received widespread attention in cancer treatment due to its excellent characteristics, such as reducing the adverse side effects of chemo-drugs and improving the therapeutic effects for various cancers. In this study, RGD and DOX was conjugated to PEG by thiol-ene addition and Schiff's base reaction, respectively, to prepare the targeted and pH-sensitive antitumor prodrug nanoparticles (RGD-PEG-DOX NPs, RGD-NPs). Subsequently, the photosensitizer chlorin e6 (Ce6) was encapsulated into RGD-NPs, thus obtaining a simple and efficient chemo-photodynamic combination platform (RGD-PEG-DOX/Ce6 NPs, RGD-NPs/Ce6). This nanoparticle possessed high drug loading property of both the chemo-drug and photosensitizer and could simultaneously release them under the mild acidic microenvironment of cancer cells, which was expected to realize the synchronization therapy of chemotherapy and photodynamic therapy (PDT). Compared with free DOX and Ce6, RGD-NPs/Ce6 could significantly improve the cellular uptake capacities of DOX and Ce6, resulting in the increased contents of ROS in cancer cells and effective cytotoxicity for tumor cells (MDA-MB-231 cells and MCF-7 cells) upon a laser radiation. The in vivo experiment showed that RGD-NPs/Ce6 displayed superior tumor targeting, accumulation, and retention ability than the other groups (free DOX, free Ce6 and NPs/Ce6), and thus significantly enhancing the antitumor effect in vivo with a laser radiation. In addition, the cardiotoxicity induced by DOX was thoroughly wiped out after being loaded and delivered by the nanoparticles according to the pathological analysis. Therefore, the targeted chemo-photodynamic combination therapeutic platform may be a promising candidate for enhanced cancer therapy.

  14. Aspirin and low-molecular weight heparin combination therapy effectively prevents recurrent miscarriage in hyperhomocysteinemic women.

    Full Text Available The management of recurrent pregnancy loss (RPL still remains a great challenge, and women with polycystic ovarian syndrome (PCOS are at a greater risk for spontaneous abortion. Treatment with low-molecular-weight heparin (LMWH has become an accepted treatment option for women with RPL; however, the subgroup of women, who are likely to respond to LMWH, has not been precisely identified. The present study evaluated the efficacy of LMWH with reference to PCOS and associated metabolic phenotypes including hyperhomocysteinemia (HHcy, insulin resistance (IR and obesity. This prospective observational study was conducted at Institute of Reproductive Medicine, Kolkata, India. A total of 967 women with history of 2 or more consecutive first trimester abortions were screened and 336 were selected for the study. The selected patients were initially divided on the basis of presence or absence of PCOS, while subsequent stratification was based on HHcy, IR and/or obesity. The subjects had treatment with aspirin during one conception cycle and aspirin-LMWH combined anticoagulant therapy for the immediate next conception cycle, if the first treated cycle was unsuccessful. Pregnancy salvage was the sole outcome measure. The overall rate of pregnancy salvage following aspirin therapy was 43.15%, which was mostly represented by normohomocysteinemic women, while the salvage rate was lower in the HHcy populations irrespective of the presence or absence of PCOS, IR, or obesity. By contrast, aspirin-LMWH combined therapy could rescue 66.84% pregnancies in the aspirin-failed cases. Logistic regression analyses showed that HHcy remained a significant factor in predicting salvage rates in the PCOS, IR, and obese subpopulations controlled for other confounding factors. With regard to pregnancy salvage, combined anticoagulant therapy with aspirin and LMWH conferred added benefit to those with HHcy phenotype.

    The side effects of antitumor drugs and low treatment efficacy are two major challenges of current chemotherapy. To address these issues, we developed a new kind of smart nanocarriers that combine pH-responsive chemotherapy and near-infrared (NIR) light triggered photodynamic therapy. These nanocarriers were based on upconversion nanoparticle (UCN)-loaded folate-conjugated polymeric lipid vesicles (UFPLVs). Merocyanine 540 (MC540), as a photosensitizer, was loaded in the UFPLVs; doxorubicin hydrochloride (DOX), as an antitumor drug, was conjugated to the surfaces of UFPLVs by pH-sensitive hydrazone bonds. The newly developed MC540&DOX-UFPLVs had a nanosized structure with targeting ligand modification, so they had the potential to accumulate into tumor sites via a combination of passive and active targeting effects. An in vitro singlet oxygen test showed that the nanocarriers can generate cytotoxic singlet oxygen successfully under the irradiation of NIR light. In vitro DOX release profiles demonstrated that the nanocarriers can achieve a pH-triggered drug release. It has been demonstrated by a cellular uptake study that the nanocarriers can efficiently deliver drugs and photosensitizers into tumor cells. In vitro and in vivo combination treatments evidenced the high antitumor effects of MC540&DOX-UFPLVs under NIR light irradiation. These results suggest that the MC540&DOX-UFPLVs may be promising nanocarriers for tumor combination therapy applications.

    This study was designed as a retrospective analysis of clinical outcomes of cases of periimplantitis treated by mechanical debridement and the administration of antibiotics combined or not with the administration of either the proteolytic enzyme serratiopeptidase (SPEP) or non-steroidal anti-inflammatory drugs (NSAIDs). Clinical charts of 544 partially edentulous patients treated for periimplantitis between June 1996 and December 2010 were analyzed to obtain clinical data of the affected implants just before the beginning of treatment and 12 months later to evaluate the outcomes of combined mechanical antibiotic treatment alone or in combination with the co-administration of the anti-inflammatory SPEP or NSAIDs. The comparative analysis revealed that therapeutic outcomes were significantly different in the three groups. Failure rate in the group that received SPEP (6 percent) was significantly lower compared to the group that received NSAIDS (16.9 percent; P less than 0.01) and to the group that received no anti-inflammatory therapy (18.9 percent; P less than 0.01). Treatment including SPEP was associated with significantly better healing also when successful treatments alone were considered. The data reported in this paper strongly support the hypothesis that SPEP is a valid addition to protocols for the combined therapy of peri-implantitis. In fact, it allows to enhance success rates significantly and also favors better tissue repair around successfully treated implants as compared to other regimens.

    Forty-four patients with erectile dysfunction (ED) aged 21-72 years aged 21-72 years (mean age 61 years) were examined and treated with sildenafil and alprostadil monotherapy or combined therapy. ED was psychogenic in 9(20.5%), arterial in 12(27.2%), vein occlusive in 9(20.5%) and neurogenic in 14(31.8%) patients. Monotherapy was most effective in psychogenic ED (alprostadil--100%, sildenafil--88.9%), least effective in vein occlusive ED (alprostadil--33.3%, sildenafil--22.2%). Alprostadil was more effective in arterial and neurogenic ED (83.3 vs 66.7 and 78.6 vs 57.1%, respectively). Combination of the two drugs produced much high response: 100, 85.7 and 55.5% in arterial, neurogenic and vein occlusive ED, respectively. Thus, combined treatment with sildenafil and alprostadil is a method of choice in the treatment of ED in failure of monotherapy with these drugs or in vein occlusive ED. In the combined treatment dose of the drugs, number of side effects and cost of therapy are lower.

    Forty-seven patients with intrapelvic recurrent rectal cancer were prescribed radiation alone (17 cases), radiation and chemotherapy (18 cases) or radiation with hyperthermia (12 cases) from 1989 to 1995. To discuss efficacies and disadvantages of these combined therapies, tumor response rate, pain control rate, duration of tumor control and pain control, and influence on patients` survival were evaluated. Radiation was delivered to the whole pelvis. Mean total dose was 45.5 Gy (1.5-2 Gy/fraction). Chemotherapy consisted 5-FU or CDDP and ADM. Hyperthermia were added 3-6 times concomitantly to the radiation. In all patients receiving more than 30 Gy radiation, tumor response rate was 56.8%. Tumor response rates were 35.3%, 43.7% and 41.7% in the radiation alone group, radiation and chemotherapy group and radiation with hyperthermia group respectively. Radiation combined chemotherapy was more effective for the tumor less than 5 cm diameter than radiation alone. In cases receiving over 50 Gy radiation, combined treatments were more effective than radiation alone. Pain relief was obtained in 75.9% of patients and there were no difference between three treatment groups. Tumor control was significantly prolonged in combined groups. Median survival periods were 6, 10 and 7 months for radiation alone, radiation and chemotherapy, and radiation with hyperthermia respectively. In PR cases and for tumors under 5 cm in diameter, there were no difference between three groups. In cases receiving over 50 Gy radiation, survival period was prolonged in radiation with hyperthermia. Fourteen patients developed acute toxicity (Leucopenia) and late complication due to bowel obstruction. The incidence of bowel complication was 27.8% for radiation and chemotherapy and 33.3% for radio-hyperthermia, while 17.6%, significantly low percentage, for radiation alone. Bowel obstruction may occur positively correlated with postsurgical adhesions and infections at initial surgery. (K.H.)

    Patients 1 and 2 were treatment-naive women who had genotype 1b chronic hepatitis C. Both had IL-28B genotype TT, and amino acid substitutions of core 70 and 91 were both wild type. Search for the presence of resistance-associated variants (RAV) in non-structural (NS)3 and NS5A regions confirmed wild-type D168 and L31, along with Y93H, in both patients. These patients participated in a Japanese phase III clinical study of asunaprevir and daclatasvir at the age of 52 and 67 years, respectively, and were treated with the combination regimen for 24 weeks. However, both experienced post-treatment relapse, and then treated with triple combination therapy with simeprevir, pegylated interferon (IFN) and ribavirin at the age of 53 and 68 years, respectively, and achieved sustained virological response. A search for RAV prior to simeprevir treatment identified multiple resistance including D168E, Y93H and L31V in both patients. It has been demonstrated that, in many cases, a treatment failure with a combination of asunaprevir and daclatasvir results in acquisition of RAV in NS3 and NS5A regions and that drug-resistant mutants, particularly those in the NS5A region, survive for a long time. In these cases, direct-acting antivirals targeted towards the NS5A region may have a limited efficacy. The present case report is based on an idea that a regimen containing IFN with simeprevir could be a therapeutic option particularly for those who are likely to be highly sensitive and tolerable to IFN.

    Full Text Available Non-drug rehabilitation in Parkinson’s disease (PD has recently attracted the increasing attention of neurologists worldwide. Symptomatic medical treatment only prolongs the period of relative wellbeing and little affects the course of the disease, without preventing its progression. Today this raises the question of whether other or additional therapeutic approaches to rehabilitating patients with this disease should be sought. The elaboration and practical implementation of a program for multidisciplinary patient rehabilitation are most effective to date. This program includes combination therapy based on the use of current drugs and different variants of nondrug therapy. Within the current concept of medical treatment for PD, there are two strategic approaches: 1 to search for agents that are able to slow, delay, or stop its progression (the so-called neuroprotection and 2 to develop more effective symptomatic therapies. The latter approach is presently considered to be basic. At large, more than 40-year experience in using dopaminergic and other antiparkinsonian agents indicates that this therapy cannot drastically solve the problem of PD treatment. So nondrug care methods whose improvement has become a relevant task of current therapeutic strategy in this disease are the focus of attention today. A nonpharmacological approach to treating PD is appropriate at all its stages. Here are just some of these methods: medicinal vacation, phototherapy, sleep deprivation, electroconvulsive therapy, and transcranial magnetic stimulation. Patients’ compliance to dietary advice is of significance. The experience shows that the most accessible and efficient and safe nondrug treatment is of course a package of measures to stimulateand restore a patient’s physical activity, which encompasses special functional training programs, kinesitherapy, multisensory training,physical exercises, etc. There is a need to further accumulate experience

    Metallic nanostructures as excellent candidates for nanosensitizers have shown enormous potentials in cancer radiotherapy and photothermal therapy. Clinically, a relatively low and safe radiation dose is highly desired to avoid damage to normal tissues. Therefore, the synergistic effect of the low-dosed X-ray radiation and other therapeutic approaches (or so-called "combined therapeutic strategy") is needed. Herein, we have synthesized hollow and spike-like gold nanostructures by a facile galvanic replacement reaction. Such gold nanospikes (GNSs) with low cytotoxicity exhibited high photothermal conversion efficiency (η = 50.3%) and had excellent photostability under cyclic near-infrared (NIR) laser irradiations. We have demonstrated that these GNSs can be successfully used for in vitro and in vivo X-ray radiation therapy and NIR photothermal therapy. For the in vitro study, colony formation assay clearly demonstrated that GNS-mediated photothermal therapy and X-ray radiotherapy reduced the cell survival fraction to 89% and 51%, respectively. In contrast, the cell survival fraction of the combined radio- and photothermal treatment decreased to 33%. The synergistic cancer treatment performance was attributable to the effect of hyperthermia, which efficiently enhanced the radiosensitizing effect of hypoxic cancer cells that were resistant to ionizing radiation. The sensitization enhancement ratio (SER) of GNSs alone was calculated to be about 1.38, which increased to 1.63 when the GNS treatment was combined with the NIR irradiation, confirming that GNSs are effective radiation sensitizers to enhance X-ray radiation effect through hyperpyrexia. In vivo tumor growth study indicated that the tumor growth inhibition (TGI) in the synergistically treated group reached 92.2%, which was much higher than that of the group treated with the GNS-enhanced X-ray radiation (TGI = 29.8%) or the group treated with the GNS-mediated photothermal therapy (TGI = 70.5%).

    This is a retrospective study to evaluate the response rate, acute toxicity, and survival rate of a combined chemotherapy and radiation therapy in limited disease small cell lung cancer. Forty six patients with limited disease small-cell lung cancer who underwent combined chemotherapy and radiation therapy between October 1994 and April 1998 were evaluated. Six cycles of chemotherapy were planned either using a VIP regimen (etoposide, ifosfamide, and cis-platin) or a EP regimen (etoposide and cis-platin). Thoracic radiation therapy was planned to deliver 44 Gy using 10MV X-ray, starting concurrently with chemotherapy. Response was evaluated 4 weeks after the completion of the planned chemotherapy and radiation therapy, and the prophylactic cranial irradiation was planned only for the patients with complete responses. Acute toxicity was evaluated using the SWOG toxicity criteria, and the overall survival and disease-free survival were calculated using the Kaplan-Meier Method. The median follow-up period was 16 months (range:2 to 41 months). Complete response was achieved in 30 (65%) patients, of which 22 patients received prophylactic cranial irradiations. Acute toxicities over grade III were granulocytopenia in 23 (50%), anemia in 17 (37%), thrombo-cytopenia in nine (20%), alopecia in nine (20%), nausea/vomiting in five (11%), and peripheral neuropathy in one (2%). Chemotherapy was delayed in one patient, and the chemotherapy doses were reduced in 58 (24%) out of the total 246 cycles. No radiation esophagitis over grade III was observed, while interruption during radiation therapy for a mean of 8.3 days occurred in 21 patients. The local recurrences were observed in 8 patients and local progressions were in 6 patients, and the distant metastases in 17 patients. Among these, four patients had both the local relapse and the distant metastasis. Brain was the most common metastatic site (10 patients), followed by the liver as the next common site (4 patients).

    Treatment of stage IA non-Hodgkin`s lymphoma (NHL) of Waldeyer`s ring remains controversial, probably because of the small number of patients and the scarcity of controlled studies. Between 1981 and 1991, 316 patients with stage I NHL of Waldeyer`s ring were randomised for treatment with radiotherapy alone (extended fields), 101 patients; combined chemotherapy with a regimen of CHOP (cyclophosphamide, vincristine, doxorubicin, and prednisone) or CHOP-like (epirubicin instead of doxorubicin), 106 patients; and combined therapy (radiotherapy followed by the same combination chemotherapy), 109 patients. Median follow-up was 6.8 years. Complete response was achieved in 93, 87 and 97%, respectively. Relapses were least frequent in patients treated with combination therapy. The 5-year rate for failure-free survival was 48% for radiation therapy, 45% for the patients who were treated with chemotherapy, which was statistically significantly less than the 83% for patients treated with combined therapy (P < 0.001). Overall survival was also better in the combined therapy arm: 90%, statistically different to 58% for the patients treated with chemotherapy alone and 56% for patients treated with radiation therapy (P < 0.001). Toxicity was mild and late side-effects were not observed in any patients. From these results combined therapy should be considered as the best therapeutic approach in patients with localised NHL of Waldeyer`s ring. (author).

  7. Overcoming clinical inertia to achieve blood pressure goals: the role of fixed-dose combination therapy.

    The treatment of hypertension should cause blood pressure (BP) changes that reduce the long-term risks of cardiovascular morbidity and mortality. There are considerable clinical benefits to be gained by promptly treating patients to recognized BP goals, particularly for those at high risk. This may be achieved by the use of combination therapy as first-line treatment. However, despite widely acknowledged therapeutic guidelines, there are significant gaps between current treatment recommendations and their implementation in clinical practice. One important explanation for inadequate treatment and subsequent poor BP control is clinical inertia. Undertreatment and clinical inertia may sometimes be mistaken for treatment-resistant hypertension, as is often the case in specific patient populations whose disease is often considered a challenge to treat because of a greater risk of cardiovascular complications (e.g. Blacks, obese patients, and those with diabetes). The availability of fixed-dose drug combinations may address some of the common misconceptions thought to promote clinical inertia. Few studies have specifically focused on subpopulations with difficult-to-treat hypertension that is uncontrolled on monotherapies. One example is an ongoing 20-week, multicenter, prospective, blinded endpoint, dose-titration, treat-to-goal study evaluating the efficacy and safety of initial fixed-dose combination therapy with amlodipine/olmesartan medoxomil, and further up-titration with hydrochlorothiazide, in patients with hypertension who are uncontrolled on antihypertensive monotherapy. This study may demonstrate the benefits of treating patients with hypertension to goal using initial fixed-dose combination therapy, even in patients considered to be at a higher risk of cardiovascular complications.

    Various polymer drug conjugates (13-16) such as primaquine and dihydroartemisinin conjugated 2-propoxy substituted polyphosphazenes (13), primaquine and dihydroartemisinin conjugated 4-acetamidophenoxy substituted polyphosphazenes (14), primaquine and dihydroartemisinin conjugated 4-formyl substituted polyphosphazenes (15) and primaquine and dihydroartemisinin conjugated 4-aminoethylbenzoate substituted polyphosphazenes (16) were synthesized using substituted polyphosphazenes as polymer and primaquine and dihydroartemisinin as combination antimalarial pharmacophores and formulated to nanoparticles to achieve novel controlled combined drug delivery approach for radical cure of malaria. The polymeric backbone was suitably substituted to impart different physicochemical properties. The polymer-drug conjugates were characterized by IR, (1)H NMR, (31)P NMR and their molecular weights were determined by Gel Permeation Chromatography. The thermal properties of the conjugates (13-16) were studied by DSC and TGA. The conjugates (13-16) were then formulated to nanoparticles formulations to increase their uptake by hepatocytes and to achieve targeted drug delivery. The nanoparticle formulations were characterized by Zeta Sizer and their morphology were studied by TEM (Transmission Electron Microscopy) imaging. The nanoparticles formulations exhibited biphasic in vitro drug release profile, the initial burst release followed by a sustained release owing to the non-fickian diffusion during first step release and fickian diffusion during second step release. In vivo antimalarial efficacy was tested using Plasmodium berghei (NK65 resistant strain) infected swiss albino mice at different doses. The combination therapy exhibited promising antimalarial efficacy at lower doses in comparison to the standard drug combination. Further, this combination therapy provided protection over 35days without any recrudescence, thus proving to be effective against resistant malaria. The study

    Full Text Available AIM: To observe the therapeutic effect of corneal collagen cross-linking (CXL in combination with liposomal amphotericin B in fungal corneal ulcers. METHODS: New Zealand rabbits were induced fungal corneal ulcers by scratching and randomly divided into 3 groups, i.e. control, treated with CXL, and combined therapy of CXL with 0.25% liposomal amphotericin B (n=5 each. The corneal lesions were documented with slit-lamp and confocal microscopy on 3, 7, 14, 21 and 28d after treatment. The corneas were examined with transmission electron microscopy (TEM at 4wk. RESULTS: A rabbit corneal ulcer model of Fusarium was successfully established. The corneal epithelium defect areas in the two treatment groups were smaller than that in the control group on 3, 7, 14 and 21d (P<0.05. The corneal epithelium defect areas of the combined group was smaller than that of the CXL group (P<0.05 on 7 and 14d, but there were no statistical differences on 3, 21 and 28d. The corneal epithelium defects of the two treatment groups have been healed by day 21. The corneal epithelium defects of the control group were healed on 28d. The diameters of the corneal collagen fiber bundles (42.960±7.383 nm in the CXL group and 37.040±4.160 nm in the combined group were thicker than that of the control group (24.900±1.868 nm, but there was no difference between the two treatment groups. Some corneal collagen fiber bundles were distorted and with irregular arrangement, a large number of fibroblasts could be seen among them but no inflammatory cells in both treatment groups. CONCLUSION: CXL combined with liposomal amphotericin B have beneficial effects on fungal corneal ulcers. The combined therapy could alleviate corneal inflammattions, accelerate corneal repair, and shorten the course of disease.

    Full Text Available Purpose. Glioblastoma multiforme (GBM is optimally treated by maximal debulking followed by combined chemoradiation. Intensity modulated radiation therapy (IMRT is gaining widespread acceptance in other tumour sites, although evidence to support its use over three-dimensional conformal radiation therapy (3DCRT in the treatment of gliomas is currently lacking. We examined the survival outcomes for patients with GBM treated with IMRT and Temozolomide. Methods and Materials. In all, 31 patients with GBM were treated with IMRT and 23 of these received chemoradiation with Temozolomide. We correlated survival outcomes with patient functional status, extent of surgery, radiation dose, and use of chemotherapy. Results. Median survival for all patients was 11.3 months, with a median survival of 7.2 months for patients receiving 40.05 Gray (Gy and a median survival of 17.4 months for patients receiving 60 Gy. Conclusions. We report one of the few series of IMRT in patients with GBM. In our group, median survival for those receiving 60 Gy with Temozolomide compared favourably to the combined therapy arm of the largest randomised trial of chemoradiation versus radiation to date (17.4 months versus 14.6 months. We propose that IMRT should be considered as an alternative to 3DCRT for patients with GBM.

    The objective of this study was to construct a clinical trial profile assessing the risk of drug failure among anti-obesity agents. Research was conducted by looking at anti-obesity therapies currently on the market or in clinical trials (phases I to III) conducted from 1998 to September 2014, with the exclusion of any drugs whose phase I trial was conducted prior to January 1998. This was completed primarily through a search on http://clinicaltrials.gov where a total of 51 drugs met the search criteria. The transition probabilities were then calculated based on various classifications and compared against industry standards. The transition probability of anti-obesity agents was 8.50% whereas the transition probability of industry standards was 10.40%. Combination therapies had four times the transition probability than monotherapies, 40% and 4.75%, respectively. Therefore, it was determined that 92% of drugs fail during clinical trial testing for this indication and combination therapy appears to improve clinical trial success rates to 10-fold. © 2015 World Obesity.

  12. A mathematical model of combined therapies against cancer using viruses and inhibitors

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    This paper deals with a procedure for combined therapies against cancer using oncolytic viruses and inhibitors. Replicating genetically modified adenoviruses infect cancer cells, reproduce inside them and eventually cause their death (lysis). As infected cells die, the viruses inside them are released and then proceed to infect other tumor cells. The successful entry of virus into cancer cells is related to the presence of the coxsackie-adenovirus receptor (CAR). Mitogen-activated protein kinase kinase (known as MEK) inhibitors can promote CAR expression, resulting in enhanced adenovirus entry into cancer cells. However, MEK inhibitors can also cause G1 cell-cycle arrest, inhibiting reproduction of the virus. To design an effective synergistic therapy, the promotion of virus infection must be optimally balanced with inhibition of virus production. We introduce a mathematical model to describe the effects of MEK inhibitors and viruses on tumor cells, and use it to explore the reduction of the tumor size that can be achieved by the combined therapies. Furthermore, we find an optimal dose of inhibitor: Poptimal = 1 - μ/δ for a certain initial density of cells (where μ is the removal rate of the dead cells and δ is the death rate of the infected cells). The optimal timing of MEK inhibitors is also numerically studied.

    Bothrops atrox snakes are the leading cause of snake bites in Northern Brazil. The venom of this snake is not included in the antigen pool used to obtain the Bothrops antivenom. There are discrepancies in reports on the effectiveness of this antivenom to treat victims bitten by B. atrox snakes. However, these studies were performed using a pre-incubation of the venom with the antivenom and, thus, did not simulate a true case of envenomation treatment. In addition, the local lesions induced by Bothrops venoms are not well resolved by antivenom therapy. Here, we investigated the efficacy of the Bothrops antivenom in treating the signs and symptoms caused by B. atrox venom in mice and evaluated whether the combination of dexamethasone and antivenom therapy enhanced the healing of local lesions induced by this envenomation. In animals that were administered the antivenom 10 minutes after the envenomation, we observed an important reduction of edema, dermonecrosis, and myonecrosis. When the antivenom was given 45 minutes after the envenomation, the edema and myonecrosis were reduced, and the fibrinogen levels and platelet counts were restored. The groups treated with the combination of antivenom and dexamethasone had an enhanced decrease in edema and a faster recovery of the damaged skeletal muscle. Our results show that Bothrops antivenom effectively treats the envenomation caused by Bothrops atrox and that the use of dexamethasone as an adjunct to the antivenom therapy could be useful to improve the treatment of local symptoms observed in envenomation caused by Bothrops snakes.

    Purpose: This study describes the early clinical outcomes of a prospective phase 2 study of consolidative involved-node proton therapy (INPT) as a component of combined-mode therapy in patients with stages I to III Hodgkin lymphoma (HL) with mediastinal involvement. Methods and Materials: Between September 2009 and June 2013, 15 patients with newly diagnosed HL received INPT after completing chemotherapy in an institutional review board-approved protocol comparing the dosimetric impact of PT with those of three-dimensional conformal radiation therapy (3DCRT) and intensity modulated RT. Based on {sup 18}F-Fluorodeoxyglucose positron emission tomography/computed tomography ({sup 18}F-FDG PET/CT) response, 5 children received 15 to 25.5 cobalt Gy equivalent (CGE) of INPT after receiving 4 cycles of Adriamycin, Bleomycin, Vincristine, Etoposide, Prednisone, Cyclophosphamide or Vincristine, adriamycin, methotrexate, Prednisone chemotherapy, and 10 adults received 30.6 to 39.6 CGE of INPT after 3 to 6 cycles of Adriamycin, Bleomycine, Vinblastine, Dacarbazine. Patients were routinely evaluated for toxicity during and after treatment, using Common Terminology Criteria for Adverse Events, version 3.0, and for relapse by physical examination and routine imaging. Relapse-free survival (RFS) and event-free survival (EFS) rates were calculated using the Kaplan-Meier method from the time of diagnosis. Results: The median follow-up was 37 months (range, 26-55). Two events occurred during follow-up: 1 relapse (inside and outside the targeted field) and 1 transformation into a primary mediastinal large B cell lymphoma. The 3-year RFS rate was 93%, and the 3-year EFS rate was 87%. No acute or late grade 3 nonhematologic toxicities were observed. Conclusions: Although decades of follow-up will be needed to realize the likely benefit of PT in reducing the risk of radiation-induced late effects, PT following chemotherapy in patients with HL is well-tolerated, and disease outcomes

    The field of nanotechnology is currently undergoing explosive development on many fronts. The technology is expected to generate innovations and play a critical role in cancer therapeutics. Among other nanoparticle (NP) systems, there has been tremendous progress made in the use of spherical gold NPs (GNPs), gold nanorods (GNRs), gold nanoshells (GNSs) and gold nanocages (GNCs) in cancer therapeutics. In treating cancer, radiation therapy and chemotherapy remain the most widely used treatment options and recent developments in cancer research show that the incorporation of gold nanostructures into these protocols has enhanced tumor cell killing. These nanostructures further provide strategies for better loading, targeting, and controlling the release of drugs to minimize the side effects of highly toxic anticancer drugs used in chemotherapy and photodynamic therapy. In addition, the heat generation capability of gold nanostructures upon exposure to UV or near infrared light is being used to damage tumor cells locally in photothermal therapy. Hence, gold nanostructures provide a versatile platform to integrate many therapeutic options leading to effective combinational therapy in the fight against cancer. In this review article, the recent progress in the development of gold-based NPs towards improved therapeutics will be discussed. A multifunctional platform based on gold nanostructures with targeting ligands, therapeutic molecules, and imaging contrast agents, holds an array of promising directions for cancer research.

    X-linked severe combined immunodeficiency (SCID-X1) is a profound deficiency of T, B, and natural killer (NK) cell immunity caused by mutations inIL2RGencoding the common chain (γc) of several interleukin receptors. Gamma-retroviral (γRV) gene therapy of SCID-X1 infants without conditioning restores T cell immunity without B or NK cell correction, but similar treatment fails in older SCID-X1 children. We used a lentiviral gene therapy approach to treat five SCID-X1 patients with persistent immune dysfunction despite haploidentical hematopoietic stem cell (HSC) transplant in infancy. Follow-up data from two older patients demonstrate that lentiviral vector γc transduced autologous HSC gene therapy after nonmyeloablative busulfan conditioning achieves selective expansion of gene-marked T, NK, and B cells, which is associated with sustained restoration of humoral responses to immunization and clinical improvement at 2 to 3 years after treatment. Similar gene marking levels have been achieved in three younger patients, albeit with only 6 to 9 months of follow-up. Lentiviral gene therapy with reduced-intensity conditioning appears safe and can restore humoral immune function to posthaploidentical transplant older patients with SCID-X1.

    Both music therapy and reminiscence therapy are currently being used to increase aspects of wellbeing in older people, including those with memory diseases such as dementia, as alternatives to pharmacological treatments. There is growing evidence that combining these therapies in a focused way would provide unique wellbeing outcomes for this population. This review aims to report on the existing intervention studies that utilize both music and reminiscence activities in equal measure in elderly adult populations. A systematic review of intervention-based studies published between 1996 and 2016 was carried out: five studies were included in this review. Included studies were predominantly carried out in aged care facilities with aged populations affected by a range of conditions; all studies assessed aspects of mental well-being. The review found music reminiscence therapy to have positive effects for participants in four out of five studies. Further research incorporating qualitative methods and mapping of intervention procedures would complement existing findings. Copyright © 2017 Elsevier Ltd. All rights reserved.

    This study aimed to perform a systematic review of the effectiveness of nonsurgical treatment associated with different adjuvant therapies on periimplantitis. Different individuals, following a research process, performed a network research of controlled and randomized controlled clinical trials on PubMed, Embase/MEDLINE, with 20 years' time constraint and the last search in January 2016. From 108 articles found by the first search, they analyzed 10 full texts, and in none did they find a standard control group. When compared, mechanical therapies combined with adjuvant therapy decreased prevalence of periimplant ratios; however, some groups showed unsatisfactory results, mainly related to the probing depth and bleeding index. When comparing debridement with other nonsurgical therapies (Er:YAG, Vector, air abrasive with amino acid glycine powder), increased periimplant levels were noticed in the test and control groups, although in different periods. Despite the improvement in the periimplant indices, there is no sufficient evidence to score the best results or even to choose the best association for nonsurgical treatment of periimplantitis; hence, more trials are necessary to answer this question.

    Full Text Available Abstract Background Ocular melanoma is the leading intraocular malignancy. There is no effective treatment for metastatic ocular melanoma. We sought a treatment targeting the tumor microenvironment as well as the tumor cells. Methods Migration of HUVEC cells, the ability of HUVEC cells to form tubes, and proliferative capacity of a human ocular melanoma cell line were tested in the presence of lenalidomide and sorafenib alone and in combination. The compounds were also tested in a rat aortic ring assay and were tested in a highly aggressive human ocular melanoma xenograft model. Results Lenalidomide and Sorafenib inhibit HUVEC ability to migrate and form tubes and when used in combination the inhibition is increased. The agents alone and in combination inhibit outgrowth in the rat aortic ring model. The combination of the agents improved the inhibition over either single agent. In a xenograft model, combination therapy inhibited tumor growth over inhibition by single agent alone in a significant fashion (p Conclusion Lenalidomide and sorafenib are effective at targeting endothelial cells, inhibiting growth of ocular melanoma cells and can inhibit growth of tumors in a xenograft model as well as inhibit development of metastases. Combining these agents works in an additive to synergistic way to inhibit the growth of tumors and development of metastases.

    We have demonstrated that tumor irradiation enhanced the therapeutic effect of interleukin 2 (IL-2) on pulmonary metastases from a murine renal adenocarcinoma, Renca. To investigate the mechanism of interaction between tumor irradiation and IL-2 therapy, we have histologically evaluated the effects of each therapy alone or in combination on Renca pulmonary metastases. Following treatment of established lung metastases with irradiation and IL-2 therapy, lung sections were processed for H&E or immunohistochemical staining. We found that tumor irradiation or IL-2 therapy locally induced vascular damage, resulting in multifocal hemorrhages and mononuclear cell mobilization in the lung tissue. This effect was amplified in lungs treated with the combined therapy. Immunohistochemistry showed that irradiation produced a macrophage influx into irradiated tumor nodules, and systemic IL-2 therapy induced T-cell infiltration in tumor nodules. Lungs treated with the combined therapy exhibited massive macrophage, T-cell, and natural killer cell mobilization in disintegrating tumor nodules and in the lung tissue. This combined therapy caused a decrease in the number of proliferating tumor cells and an increase in the number of apoptotic cells, which were more marked than with either therapy alone. We suggest that the macrophages mobilized by radiation-induced tissue injury could play a role in phagocytosis of apoptotic tumor cells, processing and presenting of tumor antigens for a systemic immune response activated by IL-2. Tumor destruction may result from the concomitant action of activated T cells, natural killer cells, and macrophages infiltrating the tumor nodules.

    Epigenetic silencing and inappropriate activation of gene expression are frequent events during the initiation and progression of cancer. These events involve a complex interplay between the hypermethylation of CpG dinucleotides within gene promoter and enhancer regions, the recruitment of transcriptional corepressors and the deacetylation and/or methylation of histone tails. These epigenetic regulators act in concert to block transcription or interfere with the maintenance of chromatin boundary regions. However, DNA/histone methylation and histone acetylation states are reversible, enzyme-mediated processes and as such, have emerged as promising targets for cancer therapy. This review will focus on the potential benefits and synergistic/additive effects of combining DNA-demethylating agents and histone deacetylase inhibitors or lysine-specific demethylase inhibitors together in epigenetic therapy for solid tumors and will highlight what is known regarding the mechanisms of action that contribute to the antitumor response.

    Week-old chickens infected with Salmonella infantis when one day old were treated with antimicrobial drugs either given alone or followed by peroral inoculation of bacterial culture. The bacteria were derived from the cecal contents of adult chickens. The antimicrobial drugs used were: neomycin, neomycin plus oxytetracycline, neomycin plus polymyxin, and sulfadiazine plus trimethoprim. The combined therapy with oxytetracycline plus neomycin and bacterial culture seemed to be the most effective, although the efficacy varied between the parallel trials. Sulfadiazine plus trimethoprim followed by treatment with the bacterial culture decreased the infection rate. The bacterial culture alone also had a slight anti-salmonella effect. When only antimicrobials were given, salmonellae rapidly reappeared in the intestines when the therapy was stopped.

    Objectives To examine the long-term efficacy of combination therapy of amiodarone and bisoprolol in patients with paroxysmal atrial fibrillation (P-AF). Methods Eighty-eight patients with P-AF were divided into two groups: 44 pa-tients treated with bisoprolol and amiodarone were enrolled in group A; 44 patients treated with amiodarone alone were enrolled in group B. Survival rates, rates of conversing to permanent atrial fibrillation (AF), subjective symptom im-provement rates and secondary bradyarrhythmia rates of the two groups were measured and analyzed. Results At 12 and 24 months, the survival rates for patients free from atrial fibrillation recurrence were 75 % and 59. 1% in group A, and 54.5 % and 36.4 % in group B (P0.05, group A vs. Group B). Conclusions In patients with P-AF, bisoprolol appears to enhance the efficacy of amiodarone therapy in maintaining sinus rhythm and improving subjective symptoms.

    AIM: To assess the efficacy of hemoclip application in combination with epinephrine injection in the treatment of bleeding peptic ulcers and to compare the clinical outcomes between patients treated with such a combination therapy and those treated with epinephrine injection alone.METHODS: A total of 293 patients (211 males, 82females) underwent endoscopic therapy for bleeding peptic ulcers. Of these, 202 patients (152 males, 50females) received epinephrine injection therapy while 91patients (59 males, 32 females) received combination therapy. The choice of endoscopic therapy was made by the endoscopist. Hemostatic rates, rebleeding rates, need for emergency surgery and 30-d mortality were the outcome measures studied.RESULTS: Patients who received combination therapy were significantly older (mean age 66±16 years, range24-90 years) and more suffered from chronic renal failure compared to those who received epinephrine injection therapy alone (mean age 61±17 years, range 21-89 years).Failure to achieve permanent hemostasis was 4% in the group who received epinephrine injection alone and 11%in the group who received combination therapy. When the differences in age and renal function between the two treatment groups were taken into account by multivariate analysis, the rates of initial hemostasis,rebleeding rates, need for surgery and 30-d mortality for both treatment options were not significantly different.CONCLUSION: Combination therapy of epinephrine injection with endoscopic hemoclip application is an effective method of achieving hemostasis in bleeding peptic ulcer diseases. However, superiority of combination therapy over epinephrine injection alone, could not be demonstrated.

    Full Text Available Luis M RuilopeUnidad de Hipertensión, Hospital 12 de Octubre, Madrid, SpainAbstract: Hypertension is a major risk factor for cardiovascular disease that contributes to the premature death of millions of people each year, and identification and treatment of hypertension continues to be a challenge. Guidelines recommend that many patients will require two or more antihypertensive agents from different classes. Combining an angiotensin II receptor blocker (ARB with hydrochlorothiazide (HCTZ has been shown in clinical studies to increase the antihypertensive efficacy of both agents compared with either agent alone. This review covers several clinical trials and aims to examine several aspects of the efficacy of the combination of olmesartan and HCTZ, including dose-responsiveness, long-term efficacy, goal rate achievement, and efficacy in patients with moderate to severe hypertension. The results presented here demonstrate that olmesartan is effective when added to HCTZ monotherapy or when HCTZ is added to olmesartan monotherapy, both over the short and long term. Moderate to severe hypertension responds well to olmesartan/HCTZ combination therapy, and the great majority of patients are able to achieve recommended blood pressure targets. Thus olmesartan/HCTZ is a well-tolerated option for patients who fail to respond to monotherapy and as initial therapy in those who require large reductions in diastolic blood pressure or systolic blood pressure to achieve goal blood pressure.Keywords: hypertension, olmesartan medoxomil; hydrochlorothiazide, angiotensin II receptor blocker, thiazide diuretic

    Although photodynamic therapy (PDT), a therapeutic approach that involves a photosensitizer, light and O₂, has been principally considered for the treatment of specific types of cancers, other applications exist, including the treatment of infections. Unfortunately, PDT does not always guarantee full success since it exerts lethal effects only in cells that have taken up a sufficient amount of photosensitizer and have been exposed to adequate light doses, conditions that are not always achieved. Based on our previous experience on the combination PDT/chemotherapy, we have explored the possibility of fighting bacteria that commonly crowd infected surfaces by combining PDT with an antibiotic, which normally does not harm the strain at low concentrations. To this purpose, we employed 5-aminolevulinic acid (5-ALA), a pro-drug that, once absorbed by proliferating bacteria, is converted into the natural photosensitizer Protoporphyrin IX (PpIX), followed by Gentamicin. Photoactivation generates reactive oxygen species (ROS) which damage or kill the cell, while Gentamicin, even at low doses, ends the work. Our experiments, in combination, have been highly successful against biofilms produced by several Gram positive bacteria (i.e., Staphylococcus aureus, Staphylococcus epidermidis, etc.). This original approach points to potentially new and wide applications in the therapy of infections of superficial wounds and sores.

    When administering several anticancer drugs within a single carrier, it is important to regulate their spatial distribution so as to avoid possible mutual interference and to thus enhance the drugs' selectivity and efficiency. To achieve this, we proposed to develop human serum albumin (HSA)-based multidrug delivery systems for combination anticancer therapy. We used three anticancer agents (an organic drug [5-fluorouracil, or 5FU], a metallic agent [2-benzoylpyridine thiosemicarbazide copper II, or BpT], and a gene agent [AS1411]) to treat liver cancer and confirm our hypothesis. The structure of the HSA-palmitic acid (PA)-5FU-BpT complex revealed that 5FU and BpT, respectively, bind to the IB and IIA subdomains of HSA. Our MALDI-TOF-MS spectral data show that one AS1411 molecule is conjugated to Cys-34 of the HSA-5FU-BpT complex via a linker. Compared with unregulated three-drug combination therapy, the HSA-5FU-BpT-AS1411 complex enhances cytotoxicity in Bel-7402 cells approximately 7-fold in vitro; however, in normal cells it does not raise cytotoxicity levels. Importantly, our in vivo results demonstrate that the HSA-5FU-BpT-AS1411 complex is superior to the unregulated three-drug combination in enhancing targeting ability, inhibiting liver tumor growth, and causing fewer side effects.

    Malaria has been very prevalent vector-borne disease in India and until date bears enormous implications on health care services of the country. Over the period of time, the development of resistance to traditional antimalarials like chloroquine has been posed as major deterrent in efforts of malaria control. As the drug resistance is today universally prevalent, especially in Plasmodium falciparum species, major burden of malarial control resides with the new artemisinin drug class. However, arterolane is one of the first fully synthetic non-artemisinin antimalarial compound with rapid schizontocidal activity, hence offering an alternative to artemisinin drugs in malaria control. Piperaquine is a synthetic bisquinoline (4-amioquinoline Antimalarial) with slow and longer schizontocidal activity. Therefore their combination has been shown to provide rapid parasitemic clearance and quick relief of most malaria-related symptoms along with prevention of recrudescences. This combination was approved by Drugs Controller General of India in 2011 for treatment of uncomplicated P. falciparum malaria. The article is aimed at to review this newer prospect in antimalarial therapy for which comprehensive database search was done in Google, Google Scholar, PubMed using the terms "Malaria," "Arterolane," "OZ277," "Piperaquine," and "Artemisinin combination therapy." A total of 323 articles were screened and 28 articles were considered for this review along with the World Health Organization and National malarial program guidelines.

    The initial treatment of childhood-onset systemic lupus erythematosus (SLE) is not standardized. Although corticosteroids are the first-line therapy for SLE, long-term, high-dose steroid therapy is associated with various side effects in children. The Japanese Study Group for Renal Disease in Children (JSRDC) has carried out a multi-center, randomized, controlled trial to evaluate the efficacy and safety of corticosteroid and mizoribine (MZB) therapy as an initial treatment for newly diagnosed juvenile SLE. Twenty-eight patients were treated with a combination steroid and MZB (4-5 mg/kg/day) (group S+M) drug therapeutic regimen, while 29 patients were treated with steroid only (group S); both groups were followed up for 1 year. The time to the first flare from treatment initiation was not significantly different between the two groups (Kaplan-Meier method, p = 0.09). During the period when the steroid was given daily (day 0-183), the time to the first flare from treatment initiation was significantly longer in the patients of group S+M than in those of group S (log-rank test, p = 0.02). At the end of the study period, there were no differences in the severity of proteinuria and renal function impairment between the two groups. No patients dropped out of the trial due to adverse events. In conclusion, our combined steroid and MZB drug therapeutic regimen was not shown to be significantly better than the steroid-only therapy as initial treatment for juvenile SLE. Whether MZB administered in a higher dose would be therapeutically advantageous can only be answered by further studies.

    Full Text Available Background: hemiparetic children usually tend to avoid the use of their impaired arm and are remarkably tend to perform inherently bimanual tasks of daily living with the less impaired arm only rather than with both arms. In fact, these children actually may have never learned to use their impaired arm for certain motor tasks or may only use it in the simplest manner, so the purpose of the study was to determine the impact of combining HABIT and mirror therapy on hand grip in hemiparetic children. Methods: A total of 30 hemiparetic children divided randomly into two groups (A and B of equal number, (N of each =15. Eligibility criteria to our study were age ranged from 4-8 years, ability to score more than 50 % of grasps and associated domains of quality of upper extremity skills test (QUEST and grade 2 in manual ability classification system (MACS, assessment done by baseline hand held dynamometer for hand palmar & pinch grasp strength (in pounds at start (0 week, reassessed at 4 & 8 weeks. The treatment protocol for two groups include: 2 months total time, 3 sessions\\ week, 1.5 hour\\session. Children in study group (A received selected occupational therapy program with modified mirror apparatus while children in control group (B Children received the same occupational therapy program as in study group but without modified mirror apparatus. Results: there is significant improvement in both groups when comparing the pre and post I & II treatment mean values. However comparing the post treatment results of both groups were statistically non-significant. Conclusion: This study confirmed that combining mirror therapy and HABIT is effective in improving hand function.

    Full Text Available OBJECTIVE: A variety of methods is used in the treatment of upper extremity functional impairment after stroke.In recent years, a new therapeutic approach in the treatment of stroke rehabilitation is the mirror therapy.The purpose of this study is to investigate the efficacy of mirror therapy,which is applied through motor imagination training, combined with conventional stroke rehabilitation program on upper extremity motor and functional recovery in patients with subacute stroke. MATERIAL and METHODS: This is a randomized,prospective,controlled single-blind trial.The study included 20 patients who were diagnosed with stroke.Patients were randomly divided into two groups:first group received conventional rehabilitation program and the second group received conventional rehabilitation program plus mirror therapy on nonparetic upper extremity consisting of wrist extension daily 4 times for 15minutes per session. Both groups received the conventional rehabilitation program for 4 weeks, 5 days a week and daily 1-2h. All patients were evaluated at baseline and at the end of the treatment(week 4.The evaluations were performed by using Brunnstrom Staging, Fugl Meyer Motor Function Scale(FM,Barthel Index(BI and goniometric measurement of wrist extension. RESULTS: The Brunnstrom stage(p<0.01, total score on FM and BI scores (p<0.01 were improved at week 4 compared to the baseline, whereas wrist subscore on FM and the goniometric measurements of the wrist and wrist extension were significantly improved only in group II.The two treatment groups were not statistically different in terms of posttreatment evaluation parameters. CONCLUSION: In our study,the mirror therapy combined with conventional rehabilitation program was not superior to conventional rehabilitation program alone in terms of upper extremity motor and functional recovery.

  1. Combined EGFR and VEGFR versus single EGFR signaling pathways inhibition therapy for NSCLC: a systematic review and meta-analysis.

    Full Text Available BACKGROUND: Lung cancer is a heterogeneous disease with multiple signaling pathways influencing tumor cell survival and proliferation, and it is likely that blocking only one of these pathways allows others to act as salvage or escape mechanisms for cancer cells. Whether combined inhibition therapy has greater anti-tumor activity than single inhibition therapy is a matter of debate. Hence, a meta-analysis comparing therapy inhibiting both VEGFR and EGFR signaling pathways with that inhibiting EGFR signaling pathway alone was performed. METHODOLOGY AND PRINCIPAL FINDINGS: We searched PubMed, EMBASE database and the proceedings of major conferences for relevant clinical trials. Outcomes analyzed were objective tumor response rate (ORR, progression-free survival (PFS, overall survival (OS and toxicity. Besides, subgroup analyses were performed to investigate whether the combined inhibition therapy is best performed using combination of selective agents or a single agent with multiple targets. Six trials recruiting 3,302 patients were included in the analysis. Combined inhibition therapy was associated with a 3% improvement in OS as compared with single-targeted therapy, but this difference was not statistically significant (HR, 0.97; 95% CI, 0.89-1.05; P=0.472. Patients receiving combined inhibition therapy had significant longer PFS than the group with single-targeted therapy (HR, 0.80; 95% CI, 0.67-0.95; P=0.011. There was no difference in the ORR between the groups (OR, 1.44; 95% CI, 0.95-2.18; P=0.085. Subgroup analysis revealed that combined inhibition therapy using combination regimens was associated with statistically significant improvement in both ORR and PFS. Toxicity was greater in combined inhibition therapy. CONCLUSIONS: There is no evidence to support the use of combined inhibition therapy in unselected patients with advanced NSCLC. However, given the significant advantage in ORR and PFS, combined inhibition therapy using combination

    Glioblastoma (GBM) is a type of intracranial brain tumor, for which there is no cure. In spite of advances in surgery, chemotherapy and radiotherapy, patients die within a year of diagnosis. Therefore, there is a critical need to develop novel therapeutic approaches for this disease. Gene therapy, which is the use of genes or other nucleic acids as drugs, is a powerful new treatment strategy which can be developed to treat GBM. Several treatment modalities are amenable for gene therapy implementation, e.g. conditional cytotoxic approaches, targeted delivery of toxins into the tumor mass, immune stimulatory strategies, and these will all be the focus of this review. Both conditional cytotoxicity and targeted toxin mediated tumor death, are aimed at eliminating an established tumor mass and preventing further growth. Tumors employ several defensive strategies that suppress and inhibit anti-tumor immune responses. A better understanding of the mechanisms involved in eliciting anti-tumor immune responses has identified promising targets for immunotherapy. Immunotherapy is designed to aid the immune system to recognize and destroy tumor cells in order to eliminate the tumor burden. Also, immune-therapeutic strategies have the added advantage that an activated immune system has the capability of recognizing tumor cells at distant sites from the primary tumor, therefore targeting metastasis distant from the primary tumor locale. Pre-clinical models and clinical trials have demonstrated that in spite of their location within the central nervous system (CNS), a tissue described as 'immune privileged', brain tumors can be effectively targeted by the activated immune system following various immunotherapeutic strategies. This review will highlight recent advances in brain tumor immunotherapy, with particular emphasis on advances made using gene therapy strategies, as well as reviewing other novel therapies that can be used in combination with immunotherapy.

    Previous work has demonstrated that intestinal bacteria, such as Fusobacterium varium (F. varium), contribute to the clinical activity in ulcerative colitis (UC); thus, an antibiotic combination therapy (amoxicillin, tetracycline, and metronidazole (ATM)) against F. varium can induce and maintain UC remission. Therefore, we investigated whether ATM therapy induces a long-term alteration of intestinal microbiota in patients with UC. Patients with UC were enrolled in a multicenter, randomized, double-blind, placebo-controlled study. Biopsy samples at the beginning of the trial and again at 3 months after treatment completion were randomly obtained from 20 patients. The terminal restriction fragment length polymorphism (T-RFLP) in mucosa-associated bacterial components was examined to assess the alteration of the intestinal microbiota. Profile changes of T-RFLP in mucosa-associated bacterial components were found in 10 of 12 patients in the treatment group and in none of 8 in the placebo group. Dice similarity coefficients using the unweighted pair group method with arithmetic averages (Dice-UPGMA) confirmed that the similarity of mucosal microbiota from the descending colon was significantly decreased after the ATM therapy, and this change was maintained for at least 3 months. Moreover, at 3 months after treatment completion, the F. varium/β-actin ratio, examined by real-time PCR using nested PCR products from biopsy samples, was reduced less than 40% in 8 of 12 treated patients, which was higher, but not significantly, than in 4 of 8 patients in the placebo group. Together, these results suggest that ATM therapy induces long-term alterations in the intestinal microbiota of patients with UC, which may be associated, at least in part, with clinical effects of the therapy.

    Full Text Available Cutaneous melanoma arises from the malignant transformation of skin melanocytes; its incidence and mortality have been increasing steadily over the last fifty-years, now representing 3% of total tumors. Once melanoma metastasizes, prognosis is somber and therapeutic options are limited. However, the discovery of prevalent BRAF mutations in at least 50% of melanoma tumors led to development of BRAF inhibitors, and other drugs targeting the MAPK pathway including MEK inhibitors, are changing this reality. These recently approved treatments for metastatic melanoma have made a significant impact on patient survival; though the results are shadowed by the appearance of drug-resistance. Combination therapies provide a rational strategy to potentiate efficacy and potentially overcome resistance. Undoubtedly, the last decade has also born an renaissance of immunotherapy, and encouraging advances in metastatic melanoma treatment are illuminating the road. Immune checkpoint blockades, such as CTLA-4 antagonist-antibodies, and multiple cancer vaccines are now invaluable arms of anti-tumor therapy. Recent work has brought to light the delicate relationship between tumor biology and the immune system. Host immunity contributes to the antitumor activity of oncogene-targeted inhibitors within a complex network of cytokines and chemokines. Therefore, combining immunotherapy with oncogene-targeted drugs may be the key to melanoma control. Here we review ongoing clinical studies of combination therapies using both oncogene inhibitors and immunotherapeutic strategies in melanoma patients. We will revisit the preclinical evidence that tested sequential and concurrent schemes in suitable animal models and formed the basis for the current trials. Finally, we will discuss potential future directions of the field.

    Full Text Available Background: Multiple sclerosis is an inflammatory, chronic demyelinating disease of the central nervous system (CNS with unknown etiology. Multiple sclerosis causes disability in young people. An Immunomodulatory drug like Avonex (IFN β1a is used to prevent relapses or disease progression. The aim of this study is to evaluate efficacy of combination therapy (Avonex and doxycycline with standard therapy (Avonex in remitting-relapsing multiple sclerosis (RRMS.Materials and Method: A double blind clinical trial was conducted. During four-month study period, 46 patients with RRMS, under standard medication (Avonex, were entered into the study. Their EDSS score were between 1-5. They randomly allocated in to two study groups with 23cases in each arm (cases and controls. All cases were allocated to each group based on blocking method. They received Avonex only in control group and Avonex and doxycycline in case group. EDSS was measured in both groups in the beginning and at the end of study. First EDSS and EDSS scores at the end of first, second, third and fourth months in both groups were compared. Number and rate of clinical attacks and side effects of treatment were assessed in both groups. Results: In case group, there was significant changes between the first EDSS and final EDSS score, but there was not any statistically significant finding in control group after 4 months. There was no significant difference between case and control group in EDSS scores during four-month study period and there was not significant difference between case and control groups in clinical attacks. Combination therapy was well tolerated without additive side effects. Conclusion: It seems that combination of both Avonex and doxycycline in RRMS patients were effective, safe, and well tolerated

    The objective of this study is to systematically evaluate the efficacy of renal denervation (RD), adjusted drugs, or combined therapy for resistant hypertension (RH) through a systematic review and meta-analysis of controlled studies.Publications were comprehensively searched. Studies that investigated the effects of RD and/or adjusted drugs in lowering blood pressure (BP) were included. After quality assessment and data extraction, subgroup analyzes were first performed according to blinding method. Meta-regression and inverted funnel plots were also conducted.A total of 13 studies containing 1604 RH patients were included. Compared with control, the meta-analysis showed that RD significantly reduced office-based BP and ambulatory BP in 6 months in the unblinded studies, while no significant difference was found in the blinded studies. Meta-regression demonstrated the significant influence of blinding method on BP reduction, and further analysis revealed a significant BP reduction compared with baseline even in the control arm of blinded studies. RD had similar effects compared with adjusted drugs, and combined therapy seemed to further reduce the level of BP.The efficacy of RD was different between blinded and unblinded studies, and our data revealed a significant BP-lowering effect in the control arm of blinded studies, which was helpful to explain this finding. Furthermore, RD seemed to be equivalent to adjusted drugs, and also we suggested a potential advantage of combined therapy of RD and adjusted drugs compared with monotherapy for RH. However, more studies are warranted to better address the issue.

    three 6-hour periods (p less than 0.01); a lesser peak was noted in the evening. The effects of metoprolol and combined therapy with metoprolol and nifedipine on the circadian variation of ischemic activity were studied in two subgroups of patients in a random, double-blind study design (31 patients...... receiving metoprolol and 42 receiving combined therapy). During therapy with metoprolol the morning increase in ischemic activity was attenuated, and the highest frequency of ischemia was then noted in the evening (6 AM to 12 noon compared with 6 PM to 12 midnight; p less than 0.05). Combined therapy...... abolished the morning peak as did metoprolol monotherapy, but even the evening increase in ischemic activity was attenuated (p less than 0.05). The diurnal distribution of the mean heart rate at the onset of ischemia, when patients were off therapy, showed a morning increase similar to the increase...

    [Purpose] This study compared the effectiveness of home exercise alone versus home exercise combined with ultrasound for patients with temporomandibular joint disorders. [Subjects and Methods] This study enrolled 23 female and 15 male patients who were divided randomly into two groups. The home exercise group performed a home exercise program consisting of an exercise program and patient education, and the home exercise combined with ultrasound group received ultrasound therapy in addition to the home exercise program. Pain intensity was evaluated using a visual analogue scale. Pain free maximum mouth opening was evaluated at baseline and 2 weeks after the treatment. [Results] There was no difference between the two groups in baseline values. After the treatment, the visual analogue scale decreased and pain free maximum mouth opening scores improved significantly in each group. Additionally, both values were higher in the home exercise combined with ultrasound group than in the home exercise group. [Conclusion] The combination of home exercise combined with ultrasound appears to be more effective at providing pain relief and increasing mouth opening than does home exercise alone for patients with temporomandibular joint disorders.

    Full Text Available Preliminary reports suggest that patients with interferon (IFN-resistant chronic hepatitis C respond better to a combination of IFN-α and nonsteroidal anti-inflammatory drugs than to IFN alone. The efficacy of IFN combined with ketoprofen in the treatment of patients with IFN-resistant chronic hepatitis C was evaluated. Seventeen patients, nonresponsive after at least six months of treatment with IFN-α2b and subsequently treated with the combination of IFN-α2b plus ketoprofen for four months, were studied. Serum aminotransferases (alanine aminotransferase [ALT] and aspartate aminotransferase [AST] and serum hepatitis C virus (HCV RNA were analyzed before and throughout treatment. No patient normalized serum aminotransferases after combination therapy. There were no significant differences in mean serum ALT and AST levels before and after ketoprofen intervention. Serum HCV RNA became undetectable after treatment in only one patient, but was detectable again three months after treatment cessation. These results provide no convincing evidence that the combination of IFN-α2b with ketoprofen improves the response to IFN in patients nonresponsive to IFN alone.

    The aim of the present study was to evaluate efficacy and side effects of glycididazole sodium (CMNa) combined with radioiodine therapy for patients with DTC cervical metastases. 53 patients of DTC cervical lymph node metastasis were randomly divided into 2 groups, where 24 cases were treated with 4.44 GBq of (131)I alone, 29 cases were treated with 800 mg/m(2) of CMNa combined with 4.44 GBq of (131)I. Peripheral blood samples were collected before and after treatment to perform measurements of routine blood test, liver function, renal function, parathyroid hormone (PTH), lymphocyte micronucleus rates and chromosome mutation. The results showed that rates of complete response (CR) in CMNa combined with radioiodine group (65.5%) were significantly higher than that in radioiodine monotherapy group (37.5%). Furthermore, CMNa combined with adioiodine treatment significantly increased the percentage of thyroglobulin (Tg) reduction at 12 weeks after treatment (P0.05). These results indicate 4.44 GBq of (131)I treatment combined with 800 mg/m(2) of CMNa could significantly improve clinical efficacy of DTC patients without increasing side effects.

    Combination therapy can play a significant role in the amelioration of several toxic effects of lead (Pb) and recovery from associated cardiovascular changes. To investigate the effects of combination therapy on the cardiovascular effects of perinatal lead exposure in young and adult rats Female Wistar rats received drinking water with or without 500 ppm of Pb during pregnancy and lactation. Twenty-two- and 70-day-old rat offspring who were or were not exposed to Pb in the perinatal period received meso-dimercaptosuccinic acid (DMSA), L-arginine, or enalapril and a combination of these compounds for 30 additional days. Noradrenaline response curves were plotted for intact and denuded aortas from 23-, 52-, 70-, and 100-day-old rats stratified by perinatal Pb exposure (exposed/unexposed) and treatment received (treated/untreated). Systolic blood pressure was evaluated and shown to be higher in the 23-, 52-, 70-, and 100-day age groups with Pb exposure than in the corresponding control age groups: 117.8 ± 3.9*, 135.2 ± 1.3*, 139.6 ± 1.6*, and 131.7 ± 2.8*, respectively and 107.1 ± 1.8, 118.8 ± 2.1, 126.1 ± 1.1, and 120.5 ± 2.2, respectively (p < 0.05). Increased reactivity to noradrenaline was observed in intact, but not denuded, aortas from 52-, 70-, and 100-day-old exposed rats, and the maximum responses (g of tension) in the respective Pb-exposed and control age groups were as follows: 3.43 ± 0.16*, 4.32 ± 0.18*, and 4.21 ± 0.23*, respectively and 2.38 ± 0.33, 3.37 ± 0.13, and 3.22 ± 0.21, respectively (p < 0.05). All treatments reversed the changes in vascular reactivity to noradrenaline in rats perinatally exposed to Pb. The combination therapy resulted in an earlier restoration of blood pressure in Pb-exposed rats compared with the monotherapies, except for enalapril therapy in young rats. These findings represent a new approach to the development of therapeutic protocols for the treatment of Pb-induced hypertension.

    Full Text Available Few studies reported the efficacy and safety in combination of clozapine and electroconvulsive therapy (ECT in schizophrenia; systematic studies are lacking. Side effects like seizure, and confusional state are reported. Authors report two cases of delayed onset/protracted delirium with ECT and clozapine in schizophrenia, one of whom developed aspiration pneumonitis possibly due to clozapine hyper-salivation. Delirium improved with stopping of ECT and clozapine. Clozapine monotherapy restarted to previous dosages in both cases without recurrence of delirium. Authors recommend for careful monitoring for delirium in ECT augmentation on high dose clozapine. Unilateral ECT may be preferred for augmenting clozapine.

    2017-07-01

    Esophageal cancer is associated with a poor prognosis with 5-year survival rates of approximately 15% to 20%. Although patients with early stage disease may adequately be treated with a single modality, combined therapy typically consisting of neoadjuvant chemoradiation followed by esophagectomy is being adopted increasingly in patients with locally advanced disease. In patients who are not surgical candidates, definitive chemoradiation is the preferred treatment approach. All patients with newly diagnosed esophageal cancer should be evaluated in the multidisciplinary setting by a surgeon, radiation oncologist, and medical oncologist owing to the importance of each specialty in the management of these patients.

    We report a case of multinodular thyroid goiter in an 80-year-old man who successfully underwent tracheal stent placement for respiratory distress caused by the thyroid goiter and following two radiofrequency (RF) ablation sessions performed for thyroid volume reduction. This sequential treatment allowed elective stent removals four weeks after the second RF ablation session because the thyroid volume had been progressively reduced. Combination therapy of temporary airway stenting and RF ablation for the treatment of thyroid goiter has two advantages, i.e., immediate reliefs of dyspnea with airway stenting and reductions of the thyroid volume with RF ablation, and thus, allowing symptom reliefs even after the stent removals.

  1. [Drug therapy of benign prostatic hyperplasia. Is combination therapy with 5 alpha-reductase inhibitors and alpha-receptor blockers effective?].

    Science.gov (United States)

    Horninger, W; Bartsch, G

    2002-09-01

    5 alpha-reductase inhibitors and alpha 1-receptor blockers are the two main drug therapies used in the management of symptomatic benign prostatic hyperplasia. As alpha-reductase inhibitors and alpha 1-receptor blockers act through different mechanisms, a combination of the two agents might be promising. The potential benefits of combination therapy with selective alpha 1-receptor blockers and finasteride, a 5 alpha-reductase inhibitor, are currently being evaluated in several placebo-controlled prospective multicenter studies (VA Study, ALFIN Study, PREDICT Study, and MTOPS Study). The data from these studies available so far demonstrate a statistically significant benefit for the study groups receiving alpha 1-receptor blockers and combination therapy vs placebo and finasteride monotherapy in terms of symptom scores and peak urine flow rates. However, none of the studies yielded a statistically significant advantage of combination therapy over treatment with alpha 1-receptor blockers. These results should be interpreted with reference to the prostatic volume, which in the studies mentioned above was relatively low. From the results of all these studies, it can be concluded that in symptomatic patients with prostate volumes of up to 40-45 ml a combination of 5 alpha-reductase inhibitors with alpha 1-receptor blockers does not appear to provide any benefit. Yet, it can be assumed that in symptomatic patients with prostate volumes of more than 60 ml combination therapy may indeed prove more effective.

    Observe the effect of Tai Chi in combination with auricular plaster therapy on treating obesity patient with secondary hyperlipidemia. Select 45 patients who suffer from simple obesity and secondary hyperlipidemia and then adopt random digital table to divide them into a Tai Chi group, an auricular plaster therapy group and a combination group. Each group consists of 15 patients. The patients in Tai Chi group are trained with Tai Chi twice a day, while those in auricular plaster therapy are treated with auricular plaster therapy 3-5 times a day and those in the combination group are trained with Tai Chi and auricular plaster therapy twice a day. BMI, body fat percentage and blood lipid indexes are respectively detected for the selected patients in the three groups before treatment and after 180 days' treatment. After 180 days' treatment, BMI index and body fat percentage of Tai Chi group are significantly improved in comparison with those before treatment (Pplaster therapy group are not improved obviously in comparison with those before the treatment (P>0.05) but the blood lipid index is improved significantly (Pplaster therapy can show the obvious synergistic therapeutic effect and thus the combined curative effect is obviously superior to that of the single therapy method.

    Intravenous epoprostenol is recommended for World Health Organization functional class(WHO-FC) Ⅳ patients with pulmonary arterial hypertension(PAH) in the latest guidelines. However, in portopulmonary hypertension(PoP H) patients, advanced liver dysfunction and/or thrombocytopenia often makes the use of intravenous epoprostenol challenging. Here we report the cases of two WHO-FC Ⅳ PoP H patients who were successfully treated with a combination of two oral vasodilators used to treat PAH: ambrisentan and tadalafil. Oral vasodilator therapy using a combination of ambrisentan and tadalafil may be a safe and effective therapeutic option for WHO-FC Ⅳ PoP H patients and should be considered for selected patients with severe and rapidly progressing PoP H.

    [Purpose] This study assessed the effects of combined application of raloxifene and aerobic exercise on senile osteoporosis. [Subjects and Methods] A total of 70 elderly patients with osteoporosis, who treated at our hospital between April 2013 and August 2014, were divided into equal-sized observation and control groups. The control group was administered raloxifene, whereas the observation group received raloxifene treatment plus aerobic exercise. [Results] Outpatient outcomes were considered dependent variables. After treatment, the two groups differed significantly in terms of lumbar spine (L2-L4) and proximal femoral bone mineral density. The urine pyridine/creatinine ratio decreased significantly and serum calcitonin level increased significantly in the observation group. These differences were statistically significant. [Conclusion] Raloxifene combined with aerobic exercise therapy significantly improves bone density and promotes bone formation in patients with senile osteoporosis.

  10. Modelling combined chemotherapy and particle therapy for locally advanced pancreatic cancer

    2015-07-01

    Full Text Available Pancreatic ductal adenocarcinoma is the only cancer for which deaths are predicted to increase in 2014 and beyond. Combined radiochemotherapy protocols using gemcitabine and hypofractionated X-rays are ongoing in several clinical trials. Recent results indicate that charged particle therapy substantially increases local control of resectable and unresectable pancreas cancer, as predicted from previous radiobiology studies considering the high tumour hypoxia. Combination with chemotherapy improves the overall survival. We compared published data on X-ray and charged particle clinical results with or without adjuvant chemotherapy calculating the biological effective dose. We show that chemoradiotherapy with protons or carbon ions results in 1-year overall survival significantly higher than those obtained with other treatment schedules. Further hypofractionation using charged particles may result in improved local control and survival. A comparative clinical trial using the standard X-ray scheme vs. the best current standard with carbon ions is crucial and may open new opportunities for this deadly disease.

    2011-07-01

    Several classes of drugs have been developed to treat type 2 diabetes mellitus (T2DM). Pioglitazone is now the only thiazolidinedione approved for the treatment of T2DM and can be administered in combination with metformin, sulfonylureas, exenatide, dipeptidyl peptidase 4 (DPP-4) inhibitors or insulin. It improves glycemic control with an extremely low incidence of hypoglycemia. In addition to reducing insulin resistance, it may also improve pancreatic beta-cell secretory function. Moreover, it exhibits a variety of favorable pleiotropic effects. The latter include anti-inflammatory, antioxidant, vasoprotective, antihypertensive and hypolipidemic actions. Finally, this agent has been shown to improve experimental diabetic neuropathy and alleviate neuropathic pain, as well as decreasing urinary albumin excretion in patients with diabetes. Thus, pioglitazone emerges as a valuable hypoglycemic agent for combination therapy in T2DM. Importantly, however, patients should be appropriately selected, especially to avoid those with heart failure, in order to minimize adverse events attributable to water retention.

    Fludarabine combination chemotherapy achieves high response rates in chronic lymphocytic leukemia (CLL) and indolent lymphoma. The aim of this study was to investigate the incidence and characteristics of treatment-related myelodysplasia and acute myeloid leukemia (t-MDS/AML) after treatment with fludarabine in combination for lymphoproliferative disorders and identify risk factors for its development. In all, 176 patients treated with fludarabine combination were followed for a median of 41 months (range 6-125 months). In all, 19 cases of t-MDS/AML have been identified for an overall rate of 10.8%. Median overall survival post-t-MDS/AML diagnosis was 11 months. Patients developing t-MDS/AML included 11/54 with follicular lymphoma (FL) (crude rate 20.4%), 5/82 with CLL (6.1%) and 3/24 with Waldenstrom macroglobulinemia or marginal zone lymphoma (12.5%). Most patients had other cytotoxic treatments (median 4, range 0-7) but three with FL had fludarabine combination as their only line of treatment. Of the eleven patients (6.3%) who received mitoxantrone with their first fludarabine combination, four (36.4%) developed t-MDS/AML (P=0.007). There was a trend toward prior cytotoxic therapy increasing the risk for t-MDS/AML (P=0.067). Fludarabine combination chemotherapy is associated with a moderate risk of t-MDS/AML particularly when combined with mitoxantrone. This complication should be considered when evaluating the potential benefit of this treatment in lymphoproliferative disorders.

    Metformin (Met) and coenzyme Q10 (CoQ10) are reported to have therapeutic functions in several inflammatory diseases. These drugs have shown anti-inflammatory effects and have been utilized in mouse models of rheumatoid arthritis (RA). However, there is no evidence of the additive effect of Met and CoQ10 in RA. Although Met and CoQ10 may be involved in the improvement of mitochondrial dysfunction, limited information is available regarding whether this effect can improve mitochondrial dysfunction in RA in particular. In this study, we sought to determine whether Met and CoQ10 attenuate the severity of collagen-induced arthritis (CIA) and show an additive effect in a mouse model. The combination of Met and CoQ10 improved CIA, reducing joint inflammation, Th17 differentiation and IgG production. In contrast, the combination of Met and CoQ10 induced Treg differentiation. Osteoclastogenesis was reduced by the combination of Met and CoQ10. The protein expression of interleukin-1β, interleukin-6 and tumor necrosis factor-alpha in mice splenocytes exposed to lipopolysaccharide decreased after drug combination therapy. We also found that the expression of JC-1 and COX IV were enhanced by treatment with the combination of Met and CoQ10. Moreover, the combination of Met and CoQ10 promoted mitochondrial O2 consumption. These findings suggest that the combination of Met and CoQ10 reduced CIA severity, improving mitochondrial dysfunction compared to Met or CoQ10 alone. These results present a novel, significant preventive targets in RA and may enhance our understanding of its pathogenesis.

    Pancreatic cancer is a common malignancy of gastrointestinal system, with features of early metastasis, easy invasion to adjacent tissues and organs and neural metastasis. Therapies include surgery, chemotherapy, radiotherapy, physi-cal and biological therapy and so on. Surgical management, including radical resection and palliative operation, is a major approach. Radiotherapy and chemotherapy could improve the resectional rate and decrease the tumor dissemination. Physical and biological therapies are widely recommended, and there is a rapid progress in zoopery. However, the efficacy of all the thera-pies is far from satisfactory. Recently, the therapy consisting of surgical resection, radiotherapy, chemotherapy, physical and biological therapy in increasing the long-term survival rate and improving the life quality of patients, along with combined thera-py has attracted the attention of surgeons.

    Full Text Available Potential benefits of combination antibiotic therapy for the treatment of plague have never been evaluated. We compared the efficacy of a ciprofloxacin (CIN and gentamicin (GEN combination therapy with that of each antibiotic administered alone (i against Yersinia pestis in vitro and (ii in a mouse model of bubonic plague in which animals were intravenously injected with antibiotics for five days, starting at two different times after infection (44 h and 56 h. In vitro, the CIN+GEN combination was synergistic at 0.5x the individual drugs' MICs and indifferent at 1x- or 2x MIC. In vivo, the survival rate for mice treated with CIN+GEN was similar to that observed with CIN alone and slightly higher than that observed for GEN alone 100, 100 and 85%, respectively when treatment was started 44 h post challenge. 100% of survivors were recorded in the CIN+GEN group vs 86 and 83% in the CIN and GEN groups, respectively when treatment was delayed to 56 h post-challenge. However, these differences were not statistically significant. Five days after the end of treatment, Y. pestis were observed in lymph nodes draining the inoculation site (but not in the spleen in surviving mice in each of the three groups. The median lymph node log(10 CFU recovered from persistently infected lymph nodes was significantly higher with GEN than with CIN (5.8 vs. 3.2, p = 0.04 or CIN+GEN (5.8 vs. 2.8, p = 0.01. Taken as the whole, our data show that CIN+GEN combination is as effective as CIN alone but, regimens containing CIN are more effective to eradicate Y. pestis from the draining lymph node than the recommended GEN monotherapy. Moreover, draining lymph nodes may serve as a reservoir for the continued release of Y. pestis into the blood - even after five days of intravenous antibiotic treatment.

Despite the significant advances, challenges remain on which combination strategies will provide the optimal response for any given patient. Defining optimal combination strategies and corresponding companion diagnostics, that will guide clinical decisions are required to target relapsed or refractory multiple myeloma (RRMM in order to improve disease progression, survival and quality of life for patients with MM. Elotuzumab is a humanized monoclonal antibody that targets signaling lymphocytic activation molecule F7 (SLAMF7, approved by the US Food and Drug Administration (FDA in 2015 and the European Medicines Agency in 2016 for the treatment of MM. SLAMF7 is expressed in normal and malignant plasma cells and has lower expression on natural killer (NK cells. Experimental evidence indicates that elotuzumab exhibits anti-myeloma activity through 1 antibody-dependent cell-mediated cytotoxicity, 2 enhancing NK cells cytotoxicity and 3 interfering with adhesion of MM cells to bone marrow stem cells (BMSCs. Although elotuzumab has no single agent activity in patients with RRMM who have received one to three prior therapies, the combination of elotuzumab with anti-myeloma agents, such as immunomodulatory drugs-lenalidomide, or proteasome inhibitors (PIs-bortezomib, remarkably improved the overall response rates and progression-free survival in MM patients with only minimal incremental toxicity. In brief, the clinical data for elotuzumab indicate that targeting SLAMF7 in combination with the use of conventional therapies is feasible and

    [Purpose] The objective of this study was to investigate the effects of mirror therapy combined with exercise tasks on the function of the upper limbs and activities of daily living. [Subjects and Methods] Twenty-five stroke patients who were receiving physical therapy at K Hospital in Gyeonggi-do, South Korea, were classified into a mirror therapy group (n=12) and a conventional therapy group (n=13). The therapies were applied for 30 minutes per day, five times per week, for a total of four weeks. Upper limb function was measured with the Action Research Arm test, the Fugl-Meyer Assessment, and the Box and Block test, and activities of daily living were measured with the Functional Independence Measure. A paired test was performed to compare the intragroup differences between before training and after four weeks of therapy, and an independent t-test was performed to compare the differences between the two groups before and after four weeks of therapy. [Results] In the intragroup comparison, both groups showed significant differences between measurements taken before and after four weeks of therapy. In the intergroup comparison, the mirror therapy group showed significant improvements compared with the conventional therapy group, both in upper limb function and activities of daily living. [Conclusion] The findings of this study demonstrated that mirror therapy is more effective than conventional therapy for the training of stroke patients to improve their upper limb function and activities of daily living.

    X-linked severe combined immunodeficiency (SCID-X1) is an inherited genetic immunodeficiency associated with mutations in the common cytokine receptor γ chain (γc) gene, and characterized by a complete defect of T and natural killer (NK) cells. Gene therapy for SCID-X1 using conventional retroviral (RV) vectors carrying the γc gene results in the successful reconstitution of T cell immunity. However, the high incidence of vector-mediated T cell leukemia, caused by vector insertion near or within cancer-related genes has been a serious problem. In this study, we established a gene therapy model of mouse SCID-X1 using a modified foamy virus (FV) vector expressing human γc. Analysis of vector integration in a human T cell line demonstrated that the FV vector integration sites were significantly less likely to be located within or near transcriptional start sites than RV vector integration sites. To evaluate the therapeutic efficacy, bone marrow cells from γc-knockout (γc-KO) mice were infected with the FV vector and transplanted into γc-KO mice. Transplantation of the FV-treated cells resulted in the successful reconstitution of functionally active T and B cells. These data suggest that FV vectors can be effective and may be safer than conventional RV vectors for gene therapy for SCID-X1.

    In the treatment of recurrent breast cancer in patients previously treated with anthracycline drugs, taxane drugs are generally used. This time, we retrospectively studied the safety of docetaxel/cyclophosphamide combination therapy (hereinafter referred to as TC therapy). Ten patients (mean age: 52.8 years old) were included in the study. Metastatic/recurrent sites included 3 skin, 2 each of contralateral breast, lung and bone, and 1 each of liver, carcinomatous pleurisy and supraclavicular lymph node. Seven patients had a history of anthracycline treatment. The patients received TC at doses of 60 mg/m(2) and 500 mg/m(2), respectively, every 3 weeks. With regard to adverse events, non-hematotoxic events included alopecia in all the patients, generalized malaise in 5, and abnormal nail in 1. Hematotoxic events were grades 2 and 3 decreased neutrophil count in 5 patients. One patient had grade 4 pyrexia associated with oral candida. The patient was admitted and treated with fluid replacement and granulocyte colony-stimulating factor (G-CSF). There were no other patients in whom the treatment was prolonged or dosage was reduced due to adverse reactions. TC therapy is considered to be a beneficial treatment method in terms of safety since it can be instituted on an outpatient basis.

METHODS:A retrospective study was performed for 6 eyes(6 casesdiagnosed as CCH. Before treatment, OCT examination showed macular cystoid edema and retinal neurepithelium layer detachment in all patients. All patients underwent photodynamic therapy, then intravitreal injection of ranibizumab 0.5mg(0.05mLwere administered at 48h after PDT. The best corrected visual acuity(BCVA, examination of the ocular fundus, fundus photography, fluorescence fundus angiography(FFA, indocyanine green angiography(ICGA, eye B ultrasonic and optical coherence tomography(OCTwere performed respectively at 1, 3 and 6mo after treatment. RESULTS:The patients were followed up for 4 to 10mo, the final vision of follow-up increased than before, it was raised 7 lines. The images of ICGA revealed hypofluorescence or no leakage in focal area. Eye B ultrasonic showed that hemangioma shrunk or faded. The images of ICGA revealed macular region retinal reattached well and edema disappeared completely. Mean flow-up was 6mo postoperative. There had no evidence of recurrence. CONCLUSION:For CCH patients, hemangioma got smaller obviously by PDT. Intravitreal ranibizumab injection promote effusion absorption under the retina. Combining use of the two therapies could improve visual acuity in a short-term.

    More than 20 years ago, X-linked severe combined immunodeficiency (SCID-X1) appeared to be the best condition to test the feasibility of hematopoietic stem cell gene therapy. The seminal SCID-X1 clinical studies, based on first-generation gammaretroviral vectors, demonstrated good long-term immune reconstitution in most treated patients despite the occurrence of vector-related leukemia in a few of them. This gene therapy has successfully enabled correction of the T cell defect. Natural killer and B cell defects were only partially restored, most likely due to the absence of a conditioning regimen. The success of these pioneering trials paved the way for the extension of gene-based treatment to many other diseases of the hematopoietic system, but the unfortunate serious adverse events led to extensive investigations to define the retrovirus integration profiles. This review puts into perspective the clinical experience of gene therapy for SCID-X1, with the development and implementation of new generations of safer vectors such as self-inactivating gammaretroviral or lentiviral vectors as well as major advances in integrome knowledge.

    Objective: To observe clinical therapeutic effects of acupuncture combined with music therapy for treatment of cerebral palsy. Methods: Sixty children with cerebral palsy were randomly divided into an acupuncture group (Group Acup.) and an acupuncture plus music group (Group Acup.+ M). Simple acupuncture was applied in Group Acup., and acupuncture at 5 groups of points plus music were applied in Group Acup. +M. The treatment was given once every two days with 3 treatments weekly, and 36 treatments constituted a therapeutic course. Therapeutic effects including movement improvement were observed for comparison after 3 courses of treatments. Results: The comprehensive functions were elevated in both groups, and the total effective rate in Group Acup. + M was obviously better than that in Group Acup (P<0.05). Movement functions were also improved in both groups, but the differences in improvement of creeping and kneeling, standing, and walking were significant between the two groups (P<0.01), showing the effect in Group Acup. +M was better than that in Group Acup.. Conclusion: The therapy of acupuncture plus music gained better therapeutic effect on cerebral palsy than simple acupuncture, which provided new thoughts for treating the disease by comprehensive therapies.

    Median overall survival (OS) of patients with metastatic colorectal cancer (mCRC) has reached up to 30months in recent clinical trials of first line therapies. Following disease progression after the standard in both, 1st and 2nd line, combination chemotherapy with monoclonal antibodies, many patients maintain a good performance status and a significant proportion is motivated to undergo further therapy. Choices of treatment beyond the second line setting for mCRC are therefore becoming increasingly important. New options have entered the therapeutic field recently: Regorafenib is a multikinase inhibitor approved for mCRC patients who have progressed on chemotherapy (including fluoropyrimidines, irinotecan, and oxaliplatin), plus VEGF inhibitor(s) and - if RAS wild-type - an anti-EGFR inhibitor. Regorafenib significantly improved OS, compared to placebo, in two phase III trials (CORRECT and CONCUR) in mCRC patients. Trifluridine/Tipiracil, an oral fluoropyrimidine, also resulted in significantly improved OS when compared to placebo in the phase III RECOURSE trial, which was conducted in a similar patient population to CORRECT. Reintroduction of previously administered therapy is another valid and commonly used approach, especially for those regimens which were discontinued before progression, e.g. if associated with cumulative toxicities, such as peripheral neuropathy or due to treatment breaks. Re-challenge of drugs to which patients developed resistance is also feasible although evidence for this strategy is limited. Copyright © 2017 The Authors. Published by Elsevier Ltd..
