Data were collected for 1735 patients treated with NECT in nine disease endemic countries during 2010–2011. At least one adverse event (AE was described in 1043 patients (60.1% and a total of 3060 AE were reported. Serious adverse events (SAE were reported for 19 patients (1.1% of treated, leading to nine deaths (case fatality rate of 0.5%. The most frequent AE were gastrointestinal disorders (vomiting/nausea and abdominal pain, followed by headache, musculoskeletal pains, and vertigo. The most frequent SAE and cause of death were convulsions, fever, and coma that were considered as reactive encephalopathy. Two hundred and sixty-two children below 15 years old were treated. The characteristics of AE were similar to adults, but the major AE were less frequent in children with only one SAE and no deaths registered in this group. Gastrointestinal problems (vomiting and abdominal pain were more frequent than in adults, but musculoskeletal pains, vertigo, asthenia, neuropsychiatric troubles (headaches, seizures, tremors, hallucinations, insomnia were less

    Various adjunctive treatments are now frequently used in combination with PUVA therapy with the aims of limiting adverse effects, improving efficacy and decreasing the cost of treatment. In the management of psoriasis, PUVA plus retinoids, PUVA plus methotrexate and PUVA plus UVB phototherapy are the most frequently used combinations. PUVA plus topical corticosteroids and PUVA plus anthralin are also efficacious but adverse effects and poor acceptance by patients are limiting factors. Combinations of PUVA plus nitrogen mustard and ionizing radiation are used in mycosis fungoides to treat tumors and residual disease in secluded sites. In the management of photodermatoses with PUVA therapy, prednisone is often required to prevent exacerbation of disease. A combination of prednisone and PUVA therapy can also be useful in lichen planus and atopic eczema. The selection of a suitable combination treatment, will depend upon the preferences of the clinician, the disease being treated, and the characteristics of the patient.

  4. Strategies for combinational cancer therapies

    The countless pre-clinical studies and many clinical trials that have applied tumor antigen-based therapies for the cancer treatment, and although the necessary tumor-specific immune response may be elicited in tumor-bearing hosts, this was not sufficient for the positive therapeutic outcome since there are multiple mechanisms that tumors develop to escape immune surveillance. The tumor-mediated inhibitory mechanisms involve co-inhibitory receptor-ligand interactions, such as PD-1/ PD-L1, secretion of inhibitory molecules, such as TGFb, and recruitment of suppressive cells, such as regulatory T cells (Treg), myeloid derived suppressor cells (MDSC), etc. Therefore, we hypothesized that successful cancer immunotherapy requires not only induction and enhancement of effector immune response but also simultaneous targeting of suppressor arm of immune system, thus in addition to enhancing antigen-specific immunity using vaccines or radiation therapy, one should also target tumor-mediated immune suppression to improve the overall efficacy of therapy. We developed multiple strategies to target various tumor-mediated immune inhibitory mechanisms that can enhance anti-tumor immunity and restructure tumor microenvironment to allow effector cells generated due to vaccination or radiation therapy to function potently. We evaluated the immune and therapeutic efficacy of multiple combinational therapies, including blocking and agonist antibodies to co-inhibitory/co-stimulatory molecules, such as PD-1, PD-L1, OX40, CTLA-4, GITR, inhibitors and neutralizing antibodies to inhibitory cytokines/molecules, such as IL-10, TGFb, IDO, and small molecules for selective inhibition of Tregs. In addition to evaluation of anti-tumor efficacy we are also investigated cellular and molecular mechanisms of action for these agents when combined with vaccine or radiation therapy and exploring the interactions between compounds within combinational therapies in animal tumor models.

    Human African trypanosomiasis (HAT) is a parasitic disease affecting sub-Saharan Africa. The parasites are able to traverse the blood-brain barrier (BBB), which marks stage 2 (S2) of the disease. Delivery of anti-parasitic drugs across the BBB is key to treating S2 effectively and the difficulty in achieving this goal is likely to be a reason why some drugs require highly intensive treatment regimes to be effective. This study aimed to investigate not only the drug transport mechanisms utilised by nifurtimox at the BBB, but also the impact of nifurtimox-eflornithine combination therapy (NECT) and other anti-HAT drug combination therapies (CTs) on radiolabelled-nifurtimox delivery in an in vitro model of drug accumulation and the human BBB, the hCMEC/D3 cell line. We found that nifurtimox appeared to use several membrane transporters, in particular breast-cancer resistance protein (BCRP), to exit the BBB cells. The addition of eflornithine caused no change in the accumulation of nifurtimox, nor did the addition of clinically relevant doses of the other anti-HAT drugs suramin, nifurtimox or melarsoprol, but a significant increase was observed with the addition of pentamidine. The results provide evidence that anti-HAT drugs are interacting with membrane transporters at the human BBB and suggest that combination with known transport inhibitors could potentially improve their efficacy.

    The importance of polichemotherapy in multibacilar leprosy (LL and LD) in patients without any previous therapy as in those diagnosticated and under monotherapy most of all in the resistance patients is presented. Sulphones, clofazimine and rifampicine are selected as first rate drugs and protionamide-etionamide as second rate drugs. The therapy plans with the association of two and three drugs and the convenience of continuing indefinitely with at least one of the drugs are presented insisting on the advantages of the clofazimine-sulphones and rifampicine-sulphones associations. The necessity of immunotherapy for recover of celular immunity against the bacilus, is the only form of preventing relapses and drug resistance.

  7. Chemotherapy and molecular target therapy combined with radiation therapy

    2012-01-01

    Combined chemotherapy and radiation therapy has been established as standard treatment approach for locally advanced head and neck cancer, esophageal cancer and so on through randomized clinical trials. However, radiation-related morbidity such as acute toxicity also increased as treatment intensity has increased. In underlining mechanism for enhancement of normal tissue reaction in chemo-radiation therapy, chemotherapy enhanced radiosensitivity of normal tissues in addition to cancer cells. Molecular target-based drugs combined with radiation therapy have been expected as promising approach that makes it possible to achieve cancer-specific enhancement of radiosensitivity, and clinical trials using combined modalities have been performed to evaluate the feasibility and efficacy of this approach. In order to obtain maximum radiotherapeutic gain, a detailed understanding of the mechanism underlying the interaction between radiation and Molecular target-based drugs is indispensable. Among molecular target-based drugs, inhibitors targeting epidermal growth factor receptor (EGFR) and its signal transduction pathways have been vigorously investigated, and mechanisms regarding the radiosensitizing effect have been getting clear. In addition, the results of randomized clinical trials demonstrated that radiation therapy combined with cetuximab resulted in improvement of overall and disease-specific survival rate compared with radiation therapy in locally advanced head and neck cancer. In this review, clinical usefulness of chemo-radiation therapy and potential molecular targets for potentiation of radiation-induced cell killing are summarized. (author)

    Full Text Available Abstract Patients with congestive heart failure (CHF that are not eligible for transplantation have limited therapeutic options. Stem cell therapy such as autologous bone marrow, mobilized peripheral blood, or purified cells thereof has been used clinically since 2001. To date over 1000 patients have received cellular therapy as part of randomized trials, with the general consensus being that a moderate but statistically significant benefit occurs. Therefore, one of the important next steps in the field is optimization. In this paper we discuss three ways to approach this issue: a increasing stem cell migration to the heart; b augmenting stem cell activity; and c combining existing stem cell therapies to recapitulate a "therapeutic niche". We conclude by describing a case report of a heart failure patient treated with a combination stem cell protocol in an attempt to augment beneficial aspects of cord blood CD34 cells and mesenchymal-like stem cells.

    Currently, the development of medicines for complex diseases requires the development of combination drug therapies. It is necessary because in many cases, one drug cannot target all necessary points of intervention. For example, in cancer therapy, a physician often meets a patient having a genomic profile including more than five molecular aberrations. Drug combination therapy has been an area of interest for a while, for example the classical work of Loewe devoted to the synergism of drugs was published in 1928-and it is still used in calculations for optimal drug combinations. More recently, over the past several years, there has been an explosion in the available information related to the properties of drugs and the biomedical parameters of patients. For the drugs, hundreds of 2D and 3D molecular descriptors for medicines are now available, while for patients, large data sets related to genetic/proteomic and metabolomics profiles of the patients are now available, as well as the more traditional data relating to the histology, history of treatments, pretreatment state of the organism, etc. Moreover, during disease progression, the genetic profile can change. Thus, the ability to optimize drug combinations for each patient is rapidly moving beyond the comprehension and capabilities of an individual physician. This is the reason, that biomedical informatics methods have been developed and one of the more promising directions in this field is the application of artificial intelligence (AI). In this review, we discuss several AI methods that have been successfully implemented in several instances of combination drug therapy from HIV, hypertension, infectious diseases to cancer. The data clearly show that the combination of rule-based expert systems with machine learning algorithms may be promising direction in this field. © The Author(s) 2018.

    Introuction. One of the risk factors for LUTS is an infravesical obstruction, which is most often caused by benign prostatic hyperplasia (BPH). BPH symptoms are formed due to three components: static (mechanical), dynamic, and impaired functional capacity of the bladder. Medical treatment with 1-blockers decreases the outflow obstruction. 5-alpha reductase inhibitors are used to inhibit the static component of BPH. To investigate the effectiveness of various modifications of medical therapy of BPH using -blockers and 5-reductase inhibitors and combinations thereof. The study comprised 90 BPH patients who were divided into three groups, with each group containing 30 people. Patients of group I, II and III received monotherapy with -blockers, a combination of 5-reductase and -blockers, and fixed-dose combination drug Duodart, respectively. Evaluation of the treatment effectiveness included filling out voiding diaries, completing the I-PSS and QL questionnaires, uroflowmetry, transrectal ultrasonography of the prostate and estimation of the incidence of adverse effects. Also, compliance with the treatment was evaluated, and the number of patients who had episodes of acute urinary retention and required surgical treatment during the 12 month treatment course was registered. Compared to monotherapy, combination therapy with -blockers and 5-reductase inhibitors more effectively reduces the LUTS, increases Qmax and prevents the disease progression, which manifests in a lower incidence of AUR and fewer surgical interventions in groups II and III. However, the combination therapy can be associated with some side effects. Patients who received fixed-dose combination drug Duodart had a greater compliance rate than patients on the combination of drugs, which, in our opinion, is associated with fewer cases of AUR and surgical interventions. The use of Duodart in patients with BPH effectively alleviates LUTS and reduces the risk of the disease progression, which manifests itself

    Full Text Available Novel drugs to treat human African trypanosomiasis (HAT are still urgently needed despite the recent addition of nifurtimox-eflornithine combination therapy (NECT to WHO Model Lists of Essential Medicines against second stage HAT, where parasites have invaded the central nervous system (CNS. The pharmacology of a potential orally available lead compound, N-methoxy-6-{5-[4-(N-methoxyamidino phenyl]-furan-2-yl}-nicotinamidine (DB844, was evaluated in a vervet monkey model of second stage HAT, following promising results in mice. DB844 was administered orally to vervet monkeys, beginning 28 days post infection (DPI with Trypanosoma brucei rhodesiense KETRI 2537. DB844 was absorbed and converted to the active metabolite 6-[5-(4-phenylamidinophenyl-furanyl-2-yl]-nicotinamide (DB820, exhibiting plasma C(max values of 430 and 190 nM for DB844 and DB820, respectively, after the 14th dose at 6 mg/kg qd. A 100-fold reduction in blood trypanosome counts was observed within 24 h of the third dose and, at the end of treatment evaluation performed four days post the last drug dose, trypanosomes were not detected in the blood or cerebrospinal fluid of any monkey. However, some animals relapsed during the 300 days of post treatment monitoring, resulting in a cure rate of 3/8 (37.5% and 3/7 (42.9% for the 5 mg/kg×10 days and the 6 mg/kg×14 days dose regimens respectively. These DB844 efficacy data were an improvement compared with pentamidine and pafuramidine both of which were previously shown to be non-curative in this model of CNS stage HAT. These data show that synthesis of novel diamidines with improved activity against CNS-stage HAT was possible.

    A scheme of therapy of radiation cystitis is suggested. It was developed on the basis of evaluation of literature data and clinical of 205 patients with radiation injury of the urinary bladder. The method is based on general and local therapy of damaged tissues by antiinflammatory drugs, anesthetics and stimulators of reparative regeneration. Severe ulcerative and incrustation cystites, refractory to conservative therapy, were treated by surgery, using antiseptics and reparation stimulators before, during and after operation. As a result, there were hardly any complications after reconstruction of the bladder with intestinal and peritoneal tissues. 104 patients (96.1%) were cured completely and ability to work was restored in 70 patients (76.9%) [ru

    2017-06-01

    Full Text Available Oncolytic virus (OV therapy utilizes replication-competent viruses to kill cancer cells, leaving non-malignant cells unharmed. With the first U.S. Food and Drug Administration-approved OV, dozens of clinical trials ongoing, and an abundance of translational research in the field, OV therapy is poised to be one of the leading treatments for cancer. A number of recombinant OVs expressing a transgene for p53 (TP53 or another p53 family member (TP63 or TP73 were engineered with the goal of generating more potent OVs that function synergistically with host immunity and/or other therapies to reduce or eliminate tumor burden. Such transgenes have proven effective at improving OV therapies, and basic research has shown mechanisms of p53-mediated enhancement of OV therapy, provided optimized p53 transgenes, explored drug-OV combinational treatments, and challenged canonical roles for p53 in virus-host interactions and tumor suppression. This review summarizes studies combining p53 gene therapy with replication-competent OV therapy, reviews preclinical and clinical studies with replication-deficient gene therapy vectors expressing p53 transgene, examines how wild-type p53 and p53 modifications affect OV replication and anti-tumor effects of OV therapy, and explores future directions for rational design of OV therapy combined with p53 gene therapy.

    Pogue, Jason M; Kaye, Keith S

    2013-09-01

    Despite many theoretical and in vitro advantages, clinical data comparing combination therapy with colistin + rifampicin to colistin alone for infection due to extremely-drug resistant (XDR) Acinetobacter baumanni are scarce and limited by small numbers and/or low quality evidence. This article represents the first large, randomized, controlled, prospective study comparing colistin monotherapy and combination therapy. The reviewed article found no difference in all cause or infection related mortality, though there was an improved rate of microbiological clearance in the combination therapy arm. This study adds important new data to the literature and sets the stage for future studies that can be designed to overcome the limitations of this study, which are discussed in detail below. Based on this study, we cannot say definitively that combination therapy is not warranted for treatment of invasive infection due to A. baumannii, but the results do suggest that rifampicin is not an ideal agent to be combined with colistin.

    Asthma treatment guidelines recommend medications based on the level of asthma control. To evaluate differences in asthma control between patients who initiated asthma controller monotherapy versus combination therapy. Children (5-16 years; n = 488) and adults (17-80 years; n = 530) with asthma and no controller therapy in the prior 6 months were included. Telephone surveys were conducted within 5 days of filling a new asthma controller prescription with either the caregiver of children or the adult patient. Demographics, asthma control before therapy, and asthma-related resource use were assessed for patients initiating monotherapy (filling one asthma controller prescription) and combination therapy (filling more than one controller medication or a fixed-dose combination). Mean pediatric age was 10 years; 53% were male. Mean adult age was 47 years; 25% were male. There were no significant differences in asthma control score between patients receiving monotherapy and combination therapy. Children on combination therapy did not have more nighttime awakening or short-acting β-agonist use but were more likely to have been hospitalized due to asthma attack (p = .05) and have more unscheduled (p = .0374) and scheduled (p = .009) physician visits. Adults on combination therapy were more likely to have been hospitalized due to asthma attack (p asthma (p asthma control scores in the 4 weeks before index medication suggests that asthma severity during a treatment-free period did not differ significantly for patients initiating controller monotherapy versus combination therapy. From these findings, it appears that although physicians may not focus on asthma control when choosing the intensity of initial controller therapy, the intensity of health-care encounters may be an influence.

    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.

Radiation response of tumor was remarkable in 35 (37%) of 95 cases, irradiated more than 5,000 rad. Yearly survival rates in 81 cases, in which the scheduled curative treatment was completed, were 63% in one, 31% in two, 21% in three, 17% in four and 13% in five years. These rates were intimately correlated to tumor size and cancer type. However, this combination therapy accompanied some fatal complications in a few percent. From the results, it was concluded that this combination therapy should be valuable to prolong the life of patients with gastric cancer, and that the curable indications for this treatment should be T1-T3: M0 cases with radio-responsive tumor.

    2014-01-01

    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.

    Hypothyroidism is currently a condition that can be treated, but not cured. Although levothyroxine reverses stigmata of hypothyroidism in most individuals, some patients feel dissatisfied with 'monotherapy', and this has stimulated interest in 'combination therapy' with both levothyroxine and liothyronine. A search of PubMed was conducted using terms including hypothyroidism, treatment, benefits, risks, and safety. Based on the articles identified, the body of evidence regarding the efficacy of traditional levothyroxine is reviewed. Concerns with levothyroxine therapy including impaired quality of life in treated patients, thyroxine-predominant hormone ratios, and inadvertent iatrogenic thyroid disease are discussed. The trials of combination therapy performed since 1999 were reviewed. The heterogeneity of these trials, both in terms of design and results, is discussed. The potential for new trials to determine whether combination therapy can reverse the dissatisfaction associated with monotherapy, while avoiding non-physiologic hormone ratios, inadvertent thyrotoxicosis, and unacceptable side effects is discussed. Expert commentary: Research regarding which therapy fully reverses hypothyroidism at a tissue and cellular level is ongoing. The field would be advanced by the development of an extended release preparation of liothyronine. In the future regeneration of functional thyroid follicles from stem cells may offer hope for curing hypothyroidism.

    The purpose of this study was to conduct a review of randomized controlled trials (RCTs) to determine the treatment effectiveness of the combination of manual therapy (MT) with other physical therapy techniques. Systematic searches of scientific literature were undertaken on PubMed and the Cochrane Library (2004-2014). The following terms were used: "patellofemoral pain syndrome," "physical therapy," "manual therapy," and "manipulation." RCTs that studied adults diagnosed with patellofemoral pain syndrome (PFPS) treated by MT and physical therapy approaches were included. The quality of the studies was assessed by the Jadad Scale. Five RCTs with an acceptable methodological quality (Jadad ≥ 3) were selected. The studies indicated that MT combined with physical therapy has some effect on reducing pain and improving function in PFPS, especially when applied on the full kinetic chain and when strengthening hip and knee muscles. The different combinations of MT and physical therapy programs analyzed in this review suggest that giving more emphasis to proximal stabilization and full kinetic chain treatments in PFPS will help better alleviation of symptoms.

    The purpose of this study was to illustrate the effects of growth hormone (GH) therapy and fixed functional appliance treatment in a 13-year-old Class II malocclusion patient without GH deficiency. GH has been shown to effectively increase endochondral growth and induce a more prognathic skeletal pattern. Although a major concern in Class II retrognathic patients is chin deficiency, long-term studies have shown that the mandibular growth enhancement effects of functional appliances are clinically insignificant. This case report demonstrates that the mandible grew significantly during fixed functional appliance treatment combined with GH therapy, with stable results during 2 years 11 months of retention. More studies are needed to evaluate GH therapy as a supplement in Class II treatment. Copyright © 2017 American Association of Orthodontists. Published by Elsevier Inc. All rights reserved.

    Lead, a ubiquitous and potent neurotoxicant causes oxidative stress which leads to numerous neurobehavioral and physiological alterations. The ability of lead to bind sulfhydryl groups or compete with calcium could be one of the reasons for its debilitating effects. In the present study, we addressed: i) if chelation therapy could circumvent the altered oxidative stress and prevent neuronal apoptosis in chronic lead-intoxicated rats, ii) whether chelation therapy could reverse biochemical and behavioral changes, and iii) if mono or combinational therapy with captopril (an antioxidant) and thiol chelating agents (DMSA/MiADMSA) is more effective than individual thiol chelator in lead-exposed rats. Results indicated that lead caused a significant increase in reactive oxygen species, nitric oxide, and intracellular free calcium levels along with altered behavioral abnormalities in locomotor activity, exploratory behavior, learning, and memory that were supported by changes in neurotransmitter levels. A fall in membrane potential, release of cytochrome c, and DNA damage indicated mitochondrial-dependent apoptosis. Most of these alterations showed significant recovery following combined therapy with captopril with MiADMSA and to a smaller extend with captopril + DMSA over monotherapy with these chelators. It could be concluded from our present results that co-administration of a potent antioxidant (like captopril) might be a better treatment protocol than monotherapy to counter lead-induced oxidative stress. The major highlight of the work is an interesting experimental evidence of the efficacy of combinational therapy using an antioxidant with a thiol chelator in reversing neurological dystrophy caused due to chronic lead exposure in rats.

    Full Text Available Streptococcus suis is a major swine pathogen, an emerging zoonotic agent responsible for meningitis, endocarditis and septicaemia followed by deafness in humans. The development of antimicrobial resistance in S. suis increases the risk for therapeutic failure in both animals and humans. In this study, we report the synergism of combination therapy against multi-resistant S. suis isolates from swine. Twelve antibiotic profiles were determined against 11 S. suis strains. To investigate their synergistic/antagonistic activity, checkerboard assay was performed for all the possible combinations. In-vitro killing curves and in-vivo treatment trials were used to confirm the synergistic activity of special combinations against S. suis dominant clones. In this study, 11 S. suis isolates were highly resistant to erythromycin, clindamycin, trimethoprim/sulfamethoxazole, and tetracycline with ratios of 80–100%, and the resistance percentages to enrofloxacin, florfenicol, and spectinomycin were ~50%. The checkerboard data identified two combination regimens, ampicillin plus apramycin and tiamulin plus spectinomycin which gave the greatest level of synergism against the S. suis strains. In-vitro kill-curves showed a bacterial reduction of over 3-logCFU with the use of combination treatments, whilst the application of mono-therapies achieve less than a 2-logCFU cell killing. In-vivo models confirm that administration of these two combinations significantly reduced the number of bacterial cells after 24 h of treatment. In conclusions, the combinations of ampicillin plus apramycin and tiamulin plus spectinomycin showed the greatest synergism and may be potential strategies for treatment of multi-resistant S. suis in animal.

    An alternative form of gene therapy involves immunoisolation of a nonautologous cell line engineered to secrete a therapeutic product. Encapsulation of these cells in a biocompatible polymer serves to protect these allogeneic cells from host-versus-graft rejection while recombinant products and nutrients are able to pass by diffusion. This strategy was applied to the treatment of cancer with some success by delivering either interleukin 2 or angiostatin. However, as cancer is a complex, multifactorial disease, a multipronged approach is now being developed to attack tumorigenesis via multiple pathways in order to improve treatment efficacy. A combination of immunotherapy with angiostatic therapy was investigated by treating B16-F0/neu melanoma-bearing mice with intraperitoneally implanted, microencapsulated mouse myoblasts (C2C12) genetically modified to deliver angiostatin and an interleukin 2 fusion protein (sFvIL-2). The combination treatment resulted in improved survival, delayed tumor growth, and increased histological indices of antitumor activity (apoptosis and necrosis). In addition to improved efficacy, the combination treatment also ameliorated some of the undesirable side effects from the individual treatments that have led to the previous failure of the single treatments, for example, inflammatory response to IL-2 or vascular mimicry due to angiostatin. In conclusion, the combination of immuno- and antiangiogenic therapies delivered by immunoisolated cells was superior to individual treatments for antitumorigenesis activity, not only because of their known mechanisms of action but also because of unexpected protection against the adverse side effects of the single treatments. Thus, the concept of a "cocktail" strategy, with microencapsulation delivering multiple antitumor recombinant molecules to improve efficacy, is validated.

    2018-02-01

    Recent developments in nanotechnology has provided new tools for cancer therapy and diagnosis. Among other nanomaterial systems, gold nanoparticles are being used as radiation dose enhancers and anticancer drug carriers in cancer therapy. Fate of gold nanoparticles within biological tissues can be probed using techniques such as TEM (transmission electron microscopy) and SEM (Scanning Electron Microscopy) due to their high electron density. We have shown for the first time that cancer drug loaded gold nanoparticles can reach the nucleus (or the brain) of cancer cells enhancing the therapeutic effect dramatically. Nucleus of the cancer cells are the most desirable target in cancer therapy. In chemotherapy, smart delivery of highly toxic anticancer drugs through packaging using nanoparticles will reduce the side effects and improve the quality and care of cancer patients. In radiation therapy, use of gold nanoparticles as radiation dose enhancer is very promising due to enhanced localized dose within the cancer tissue. Recent advancement in nanomaterial characterization techniques will facilitate mapping of nanomaterial distribution within biological specimens to correlate the radiobiological effects due to treatment. Hence, gold nanoparticle mediated combined chemoradiation would provide promising tools to achieve personalized and tailored cancer treatments in the near future.

    The advent of nanomedicine marks an unparalleled opportunity to advance the treatment of a variety of diseases, including cancer. The unique properties of nanoparticles, such as large surface-to volume ratio, small size, the ability to encapsulate a variety of drugs, and tunable surface chemistry, gives 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 nanoparticles a mode of treatment potentially superior to conventional cancer therapies. This article highlights the most recent developments in cancer treatment using nanoparticles as drug-delivery vehicles, including promising opportunities in targeted and combination therapy.

    Use of total body irradiation (TBI) and/or chemotherapy as a preparation for marrow transplantation in the treatment of leukemia has been only moderately successful in the clinic. Although cyclophosphamide (CY) has shown promise as a marrow ablative agent, leukemia relapses are often found, and optimal therapeutic protocols have not been established. Our transplantation therapy studies of murine leukemia with parental recipients and hybrid donors provide an excellent model for research aimed at improved survival of human transplant patients. Utilizing a murine leukemia induced by a virus, various doses of CY in combination with sub-lethal irradiation were compared to determine the optimal pretreatment for transplantation therapy. Both normal and leukemic mice were engrafted with virus resistant, histocompatible marrow following these preparations, then monitored for survival and long term effects. Leukemic mice were also evaluated for pluripotent as well as myeloid committed stem cells as a measure of the effectiveness of the treatment in elimination of leukemic cells. Leukemic groups were also compared for the percentage and time of leukemia relapse. All CY/X-ray combinations were more effective in elimination of stem cell populations than supralethal TBI alone. However, the best survival was obtained with lethal TBI alone or low dose CY in combination with 550 R

    The biological basis for combination therapy with radiation and bleomycin (BLM) was studied on C 2 W cells growing in vitro. When BLM was added to the medium before or after irradiation, a potentiating effect was observed. The potentiation remained for 4-6 hours after irradiation. To make clear the mechanism, both type of repair from radiation damage (Elkind type and PLD) by BLM were examined. BLM didn't inhibit the Elkind type recovery but it did inhibit the repair of potentially lethal damage (PLD repair). Plateau phase C 2 W cells were irradiated, incubated at 37 0 C for a various number of hours, then trypsinized for colony formation. PLD repair was inhibited when BLM was added immediately after irradiation. Based on such experimental results, we treated lung cancer with combination of radiation and BLM. BLM was injected intravenously within 30 minutes after irradiation. Although it seems too early to discuss the result of the combination therapy, it is very promising. (J.P.N.)

    2010-01-01

    Given the critical role of tumor vasculature in tumor development, considerable efforts have been spent on developing therapeutic strategies targeting the tumor vascular network. A variety of agents have been developed, with two general approaches being pursued. Antiangiogenic agents (AAs) aim to interfere with the process of angiogenesis, preventing new tumor blood vessel formation. Vascular-disrupting agents (VDAs) target existing tumor vessels causing tumor ischemia and necrosis. Despite their great therapeutic potential, it has become clear that their greatest clinical utility may lie in combination with conventional anticancer therapies. Radiotherapy is a widely used treatment modality for cancer with its distinct therapeutic challenges. Thus, combining the two approaches seems reasonable. Strong biological rationale exist for combining vascular-targeted therapies with radiation. AAs and VDAs were shown to alter the tumor microenvironment in such a way as to enhance responses to radiation. The results of preclinical and early clinical studies have confirmed the therapeutic potential of this new treatment strategy in the clinical setting. However, concerns about increased normal tissue toxicity, have been raised

    In this study, we investigated an effective strategy of treatment for unresectable gallbladder cancer (GBC) by the retrospective analysis of prognostic factors and anti-tumor therapies, especially combination therapy of arterial infusion chemotherapy and radiation therapy (AI+PT). Forty-three patients with unresectable GBC were enrolled, and prognostic factors were investigated by multivariate analysis using a proportional hazard model. In addition, we examined the indication and after-therapy by analyzing the each factor cumulative survival rates and anti-tumor effect about the AI + RT group (n=24). AI + RT and the responders to the first-line therapy were significant prognostic factors. In AI + RT group, median survival time, progression-free survival and the 1-year survival rate, the response and disease control rates was 15.5 months, 7.1 months, 62.5%. 54.2% and 95.8%, respectively; which suggested prolonged survival and high anti-tumor effect. Cumulative survival rate was significantly shorter in cases with distant metastasis except liver metastases, and has been tendency to extend in the group who underwent systemic chemotherapy as after-therapy. The treatment strategy, using the Al + RT as first-line with the systemic chemotherapy as after-therapy, suggested contribute to the prolonged survival in locally advanced and liver metastases cases of GBC.

    The combined effects of cisplatin and irradiation were investigated in 44 patients with bladder cancer accompanied by the infiltration of T 2 ∼T 4 cells, in a study commencing in September 1985. The antitumor effect and adverse reactions to the therapy were recorded. The majority of these patients had not undergone total bladder excision, for a variety of reasons. Thirty-two patients were male and 12 were female; the average age was 66.7 years, with ranging from 33∼83 years of age. Irradiation was performed using table cobalt 60 or a linear accelerator at a dose of 2 Gy per day, 5 days a week. The total radiation dose ranged from 40 to 70 Gy. Cisplatin was administered systemically at a dose of 20∼30 mg/day for 5 consecutive days during the first and fourth weeks of irradiation. At the time of final assessment of the antitumor effect, 24 out of 40 eligible patients (60%) had achieved complete remission (CR). The duration of CR averaged 18.8 months, with a range of 1∼50 months. The actual survival rates were as follows: 81% at 1 year, 69% at 2 years, and 52% at 3 and 4 years. Regarding adverse reactions, anorexia occurred in 28 patients (70%), nausea and vomiting in 21 (53%), diarrhea in 8 (20%), leukopenia in 16 (40%), mild thrombocytopenia in 5 (13%), and dermatitis in 8 (20%). All of these adverse reactions were mild and were alleviated after completion of the combined therapy. The present investigation demonstrated that combined therapy with cisplatin and irradiation is effective for the regional treatment of invasive bladder cancer. (author)

    To describe a case of myxedema coma (MC) associated with combination aripiprazole and sertraline therapy. A 41-year-old male presented to the emergency department with confusion, right-sided numbness and tingling, slurred speech, dizziness, and facial edema. His blood pressure was 160/113 mm Hg, with a pulse of 56 beats/min and temperature of 35.4 degrees C. Initial abnormal laboratory values included creatine kinase (CK) 439 U/L; serum creatinine 1.6 mg/dL; aspartate aminotransferase 85 U/L; and alanine aminotransferase 35 U/L. Repeat cardiac markers revealed an elevated CK level of 3573 U/L with a CK-MB of 24 ng/mL. Thyroid function tests showed thyroid-stimulating hormone 126.4 microIU/mL and free thyroxine 0.29 ng/dL. Home medications of unknown duration were sertraline 200 mg and aripiprazole 20 mg daily. He was admitted to the intensive care unit and initially treated with intravenous levothyroxine and dexamethasone. By hospital day 4, the patient was clinically stable and discharged to home. Myxedema coma, the most significant form of hypothyroidism (HT), is a rare but potentially fatal condition. The known precipitating causes of MC were ruled out in this patient, which left his home medications as the likely cause. Cases of HT caused by certain atypical antipsychotics and antidepressants are found in the literature, but none was reported with aripiprazole therapy. There are also no reported cases of sertraline or aripiprazole inducing MC. Use of the Naranjo probability scale indicates that the combination of aripiprazole and sertraline was a probable inducer of MC in this patient. Due to the widespread use of psychotropic medications, clinicians should be reminded of the rare, yet life-threatening, occurrence of MC when treating patients, especially with combination therapies such as sertraline and aripiprazole.

    Combination therapy is a common practice in many medical disciplines. It is defined as the use of more than one drug to treat the same disease. Sometimes this expression describes the simultaneous use of therapeutic approaches that target different cellular/molecular pathways, increasing the chances of killing the diseased cell. This short review is concerned with therapeutic combinations in which PDT (Photodynamyc Therapy) is the core therapeutic partner. Besides the description of the principal methods used to assess the efficacy attained by combinations in respect to monotherapy, this review describes experimental results in which PDT was combined with conventional drugs in different experimental conditions. This inventory is far from exhaustive, as the number of photosensitizers used in combination with different drugs is very large. Reports cited in this work have been selected because considered representative. The combinations we have reviewed include the association of PDT with anti-oxidants, chemotherapeutics, drugs targeting topoisomerases I and II, antimetabolites and others. Some paragraphs are dedicated to PDT and immuno-modulation, others to associations of PDT with angiogenesis inhibitors, receptor inhibitors, radiotherapy and more. Finally, a look is dedicated to combinations involving the use of natural compounds and, as new entries, drugs that act as proteasome inhibitors

    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)

    Solitary bone plasmacytoma (SBP) is a rare presentation of plasma cell dyscrasias. Radiotherapy has been considered the treatment of choice, however, most patients will develop multiple myeloma, 3 to 10 years after initial diagnosis and treatment. No innovations have been introduced in the treatment of SBP in the last 30 years. We began a prospective clinical trial to assess the efficacy and toxicity of adjuvant chemotherapy with low doses of melphalan and prednisone administered to patients with SBP after radiation therapy in an attempt to improve the disease-free survival and overall survival. Between 1982 and 1989, 53 patients with SBP were randomly assigned to be treated with either local radiotherapy with doses ranged from 4000 to 5000 cGy to achieve local control of disease (28 patients) or the same radiotherapy schedule followed by melphalan and prednisone given every 6 weeks for 3 years (25 patients). After a median follow-up of 8.9 years, disease-free survival and overall survival were improved in patients who were treated with combined therapy, 22 patients remain alive and free of disease in the combined treatment group compared to only 13 patients in the radiotherapy group (p radiotherapy in patients with SBP improved duration of remission and survival without severe side-effects. However, as with other studies in SBP, the group was too small to draw definitive conclusions and more controlled clinical trials are necessary to define the role of this therapeutic approach in patients with SBP.

    2018-03-05

    Cocrystallization is a technique for modifying the physicochemical and pharmacokinetic properties of an active pharmaceutical ingredient (API) embodying the concept of supramolecular synthon. Most of the examples cited in the literature are of cocrystals formed between an API and a coformer chosen from the generally recognized as safe (GRAS) substance list, however, few examples exist where a cocrystal consists of two or more APIs. These cocrystals are commonly known as multi API, multi drug or drug- drug cocrystals. The formation of such cocrystals is feasible by virtue of non covalent interactions between the APIs, which help them in retaining their biologic activity. In addition, drug- drug cocrystals also offer the potential solution to the limitations such as solubility, stability differences and chemical interaction between the APIs which is often faced during the traditional combination therapy. Cocrystallization of two or more APIs can be employed for delivery of combination drugs for the better and efficacious management of many complex disorders where existing monotherapies do not furnish the desired therapeutic effect. This review on the existing drug-drug cocrystals is to gain insight for better designing of multi API cocrystals with improved physicochemical and pharmacokinetic profile and its application in multiple target therapy.

    2001-01-01

    Cerivastatin is the new 3rd-generation of the synthetic 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors, the 1st drugs of choice for treating hypercholesterolemia. A potent inhibitor of HMG-CoA reductase, it possesses a high affinity for liver tissue and decreases plasma low-density lipoprotein cholesterol at microgram doses. Cerivastatin produces reductions in low-density lipoprotein cholesterol of 31.3% and 36.1% at doses of 0.3 and 0.4 mg/day, respectively. It is an uncomplicated agent with regard to its pharmacokinetic profile, low potential for interaction with other drugs, and suitability for use in those with impaired renal function. Most other statins have been implicated in causing rhabdomyolysis, either as mono-therapy or in combination with other agents. We report what to our knowledge is the most profound case yet in the literature of rhabdomyolysis in association with ceriva-statin-gemfibrozil combination therapy, in regard both to the extreme elevation in serum creatinine kinase and to the patient's near-paralytic weakness.

    The data of 14 patients with squamous cell carcinoma of the maxillary sinus who were admitted to our hospital and received radiation therapy and concurrent superselective intraarterial infusion therapy between 1998 and 2008 were analyzed to determine the effect of the primary treatment and the adverse events. The subjects were between 43 and 79 years old (median, 61 years old), and there were 10 male and 4 female patients. Superselective intraarterial infusion therapy was administered using the Seldinger method, and cisplatin (CDDP) was administered by intraarterial infusion at a total of 200 mg/m 2 . 5-fluorouracil (FU) was systemically administered by intravenous infusion at the dose of 800 mg/m 2 from day 2 to day 5. In addition, radiation therapy was given concurrently, beginning on day 2. At 4 weeks after completion of the scheduled radiation therapy combined with superselective intraarterial infusion therapy, the treatment effect was judged based on macroscopic, radiological and histopathological findings. The response rates to the primary treatment were as follows: 57.1%, complete response (CR) (8 patients) and 42.9%, partial response (PR) (6 patients). Thus, the overall response rate was 100%. As for the adverse events, while grade 4 cerebral infarction occurred in one patient, all of the other adverse events were reversible and not serious. The safety of the treatment was therefore considered to be acceptable. We are planning to investigate the long-term outcomes in a future study. (author)

Method included percutaneous transhepatic biliary drainage, endoscopic fluorescence diagnosis, photodynamic therapy of tumor stricture, and stenting of bile ducts. Fourteen patients who underwent the treatment in the surgery department clinic of I.M. Sechenov First Moscow State Medical University were enrolled in the study. Fluorescence diagnosis and photodynamic therapy were carried out using photosensitizers photosens (0.5 mg/kg, fotolon (1 mg/kg, and radachlorin (1 mg/kg. The average light dose for one session was 115±5 J/cm2. Fluorescence diagnosis using endoscopic video-fluorescence system for endoscopy and minimally invasive surgery allowed to obtain videoassisted fluorescence image of the tumor and to measure level of photosensitizer fluorescence in tumor in all patients. Malignant tumor was confirmed by morphological study in 12 patients, biopsy of material for morphological study failed in 2 patients with Klatskin tumor. The preliminary results of combined minimally invasive treatment were assessed as promising. The survival time in 4 patients after treatment accounted for 21, 17, 13 and 11 months, respectively. For now 5 patients are under follow-up. Follow-up periods are 13 and 19 months in 2 of them and from 4 to 6 months in 3 of them. Five patients with multiple distant metastases before the treatment died in 3±1 months after therapy. The average lifetime in the treatment group is 9.5 months up to date, however the duration is expected to belonger because 5 of 14 patients are alive.

    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

    2005-01-01

    The aim of this article is to present a new and challenging model of treatment that combines two therapeutic interventions: hydrotherapy and Snoezelen or controlled multisensory stimulation. The combination of the two therapeutic approaches enhances the treatment effect by utilizing the unique characteristics of each approach. We believe that this combined model will further enhance each media to the benefit of the clients and create a new intervention approach. This article relates to a hydrotherapy swimming pool facility that has been established at the Williams Island Therapeutic Swimming and Recreation Center, Beit Issie Shapiro, Raanana in Israel, after acquiring many years of experience and gaining substantial knowledge both in the field of hydrotherapy and Snoezelen intervention. Beit Issie Shapiro is a non-profit community organization providing a range of services for children with developmental disabilities and their families. The organization provides direct services for nearly 6,000 children and adults each year. This article provides an overview of hydrotherapy and Snoezelen and presents a case study, which will demonstrate the new model of treatment and show how this new and innovative form of therapy can be used as a successful intervention. We believe it will open a path to enriching the repertoire of therapists helping people with special needs. This article is also addressed to researchers to provide ideas for further studies in this area.

    Radiation therapy combined with radiofrequency (RF) hyperthermia was performed on 5 advanced cancer patients. Included were one each with urinary bladder cancer, hepatoma with left axillary node metastasis, breast cancer, tongue cancer with left cervical metastasis, and mandibular cancer. All had large tumors, which were judged to be uncontrollable by radiotherapy alone. They were treated with irradiation (Linac: 10 MV X-ray 1.8 - 2.0 Gy/day, 5 days/week), followed within an hour by RF hyperthermia once or twice a week. Partial response was obtained in the urinary bladder cancer patient. Surface overheating around the margin of electrodes occurred in all but no severe complications were observed. (author)

    2017-01-01

    Glioblastoma is the most malignant brain tumor in adults. Median survival is only about 15 months despite aggressive treatment, consisting of surgery followed by radio- and chemotherapy, stressing the need for new therapies. Development of glioblastoma is thought to be a result of both genetic...... and epigenetic alterations, ultimately leading to oncogenic transformation of normal glia cells. Several features are suggested to give rise to the poor prognosis of glioblastoma including treatment resistance, a high degree of abnormal blood vessels, and high heterogeneity, both within the single tumor and from...... patient to patient. Thus, investigations are needed to identify the genetic-molecular alterations that glioblastoma tumors depend on in order to overcome treatment and regrow after initial surgery. The findings presented in this thesis illustrate the promising potential of combinational treatments...

    1979-08-01

    Intention of this study is to detect in 49 patients suffering from prostate carcinomas, effects and side effects of radiotherapy. According to the present results, there is not any doubt that prostate carcinomas are radiosensitive. In all patients radiotherapy induced a prostate shrinkage and an increasing of consistency. It resulted that a prostate biopsy must be carried out in order to control the success of therapy. The success of the treatment depends upon tumour spreading and on its degree of differentiation. Within the observation period only in four cases metastasation of the prostate carcinoma occurred after radiotherapy. According to literature, the 5-year survival rate with an organ-defined prostate carcinoma ranges between 70 and 80% when radiotherapeutic methods are applied. The same authors indicate a 5-year survival rate between 42 and 48% for scattered carcinomas. Only minor side effects are provoked by radiotherapy. In 75% of the patients pollakisuria and dysuria resulted. After irradiation was finished, the symptoms disappeared and did not cause in any case any late complications. In 12% of the cases proctitic pain occurred during irradiation, which in 6% remained even after the treatment was terminated. We could prove unequivocally on our patients that passage impairments caused by a prostate carcinoma are improved by radiotherapy. Finally it can be said that this treatment is applicable for curing carcinoma which is localised on the prostate. In the case of an undefined, scattered carcinoma radiotherapy combined with hormone therapy is the treatment of choice. With regards to undesired side effects radiotherapy is superior to other therapeutic measures. (orig./MG) [de

    Anghel, R M; Gales, L N; Trifanescu, O G

    2016-01-01

    Rationale: Urinary bladder cancer is the fourth most common cancer in men and the eighth in women, being an important public health issue. Methods: : Medical files of 155 patients (132M/ 23F) with urinary bladder cancer treated between 2006 and 2012 were retrospectively analyzed. The median age at diagnosis was 65 years (range: 19-85 years). Disease free survival (DFS) for patients with complete tumor resection receiving adjuvant treatment and progression free survival (PFS) for patients with post-operative residual disease was estimated. Results: The distribution of the stage disease was: 50 patients (32.2%) stage II, 47 (30.3%) stage III, 58 (37.4%) stage IV. Radical cystectomy was performed in 56 patients (36.1%), while 99 patients (63.9%) underwent repeated transurethral resection of the urinary bladder tumor (TURBT). Postoperative treatment included multimodal therapy in 47 patients (30.3%) (chemotherapy and external beam radiation), external beam radiation alone in 57 patients (36.8%) and chemotherapy alone (methotrexate, vinblastine, doxorubicin, and cisplatin-MVAC or gemcitabine+platinum) in 51 patients (32.9%). After a median follow-up of 31 months (range: 3-79 months), 51 patients (32.9%) presented local recurrence, 32 patients (21%) distant recurrence (metastases), 10 patients (6.4%) both local and distant recurrence, and 62 patients (40%) were free of disease. The median duration until progression was 27 months. Discussion: Despite the combined therapy approaches, urinary bladder carcinoma remains an aggressive disease, with a high relapse rate. Earlier diagnosis, aggressive radical surgery in intention to cure (cystectomy), and adjuvant multimodal treatment (radiotherapy and chemotherapy) are needed for survival improvement.

    Anticancer therapy has always been a vital challenge for the development of nanomedicine. Repeated single therapeutic agent may lead to undesirable and severe side effects, unbearable toxicity and multidrug resistance due to complex nature of tumor. Nanomedicine-based combination anticancer therapy can synergistically improve antitumor outcomes through multiple-target therapy, decreasing the dose of each therapeutic agent and reducing side effects. There are versatile combinational anticancer strategies such as chemotherapeutic combination, nucleic acid-based co-delivery, intrinsic sensitive and extrinsic stimulus combinational patterns. Based on these combination strategies, various nanocarriers and drug delivery systems were engineered to carry out the efficient co-delivery of combined therapeutic agents for combination anticancer therapy. This review focused on illustrating nanomedicine-based combination anticancer therapy between nucleic acids and small-molecular drugs for synergistically improving anticancer efficacy.

    2006-12-28

    To investigate the therapeutic effectiveness of colonic exclusion and combined therapy for refractory constipation. Thirty-two patients with refractory constipation were randomly divided into treatment group (n = 14) and control group (n = 18). Fourteen patients in treatment group underwent colonic exclusion and end-to-side colorectal anastomosis. Eighteen patients in control group received subtotal colectomy and end-to-end colorectal anastomosis. The therapeutic effects of the operations were assessed by comparing the surgical time, incision length, volume of blood losses, hospital stay, recovery rate and complication incidence. All patients received long-term follow-up. All operations were successful and patients recovered fully after the operations. In comparison of treatment group and control group, the surgical time (h), incision length (cm), volume of blood losses (mL), hospital stay (d) were 87 +/- 16 min vs 194 +/- 23 min (t = 9.85), 10.4 +/- 0.5 cm vs 21.2 +/- 1.8 cm (t = 14.26), 79.5 +/- 31.3 mL vs 286.3 +/- 49.2 mL (t = 17.24), and 11.8 +/- 2.4 d vs 18.6 +/- 2.6 d (t = 6.91), respectively (P 0.05), 21.4% vs 33.3% (P = 0.73 > 0.05), respectively. Colonic exclusion has better therapeutic efficacy on refractory constipation. It has many advantages such as shorter surgical time, smaller incision, fewer blood losses and shorter hospital stay.

    Objective: To analyze the clinical characteristics and prognosis of the second primary lung cancer. Methods: The interval between the second primary lung cancer and the previous primary cancer ranged from 10 days to 317 months (median 49 months). Of the 129 patients treated from 1971 to 1997 by surgery only, radiotherapy only and chemotherapy only or combined therapy, 11 (8.5%) patients had stage I, 29 (22.5%) stage II, 75 (58.1%) stage III and 14 (10.9%) stage IV; 30 patients received surgery alone, 54 radiotherapy alone, 8 chemotherapy alone, 12 surgery plus radiotherapy, 20 radiotherapy plus chemotherapy, 4 surgery plus chemotherapy and 1 surgery plus radiotherapy plus chemotherapy. Results: The overall 2-, 3- and 5-year survival rates were 40.2%, 27.2% and 15.3%. The stage I, II, III and IV 2-year survival rates were 71.6%, 60.7%, 32.9% and 0%, respectively (P 49 and ≤49 months of the interval between the second primary lung cancer and the previous primary cancer (P>0.05). Conclusions: Second primary lung cancer are similar to the first primary lung cancer in clinical characteristics and prognosis. The main cause of failure is lung cancer perse. Stage and being able to operation are prognostic factors

    A significant percentage of patients infected with HIV-1 experience only suboptimal CD4 cell recovery while treated with combination therapy (cART). It is still unclear whether viral properties such as cell tropism play a major role in this incomplete immune response. This study therefore intended to follow the tropism evolution of the HIV-1 envelope during periods of suppressive cART. Viruses from two distinct patient groups, one with good and another one with poor CD4 recovery after 5 years of suppressive cART, were genotypically analysed for viral tropism at baseline and at the end of the study period. Patients with CCR5-tropic CC-motif chemokine receptor 5 viruses at baseline tended to maintain this tropism to the study end. Patients who had a CXCR4-tropic CXC-motif chemokine receptor 4 virus at baseline were overrepresented in the poor CD4 recovery group. Overall, however, the majority of patients presented with CCR5-tropic viruses at follow-up. Our data lend support to the hypothesis that tropism determination can be used as a parameter for disease progression even if analysed long before the establishment of a poorer immune response. Moreover, the lasting predominating CCR5-tropism during periods of full viral control suggests the involvement of cellular mechanisms that preferentially reduce CXCR4-tropic viruses during cART. © 2016 British HIV Association.

    Purpose: The most likely clinical application of vascular targeting agents (VTAs) is in combination with more conventional therapies. In this study, we report on preclinical studies in which VTAs were combined with hyperthermia and/or radiation. Methods and Materials: A C3H mammary carcinoma grown in the right rear foot of female CDF1 mice was treated when at 200 mm 3 in size. The VTAs were combretastatin A-4 disodium phosphate (CA4DP, 25 mg/kg), flavone acetic acid (FAA, 150 mg/kg), and 5,6-dimethylxanthenone-4-acetic acid (DMXAA, 20 mg/kg), and were all injected i.p. Hyperthermia and radiation were locally administered to tumors of restrained, nonanesthetized mice, and response was assessed using either a tumor growth or tumor control assay. Results: Heating tumors at 41.5 degree sign C gave rise to a linear relationship between the heating time and tumor growth with a slope of 0.02. This slope was increased to 0.06, 0.09, and 0.08, respectively, by injecting the VTAs either 30 min (CA4DP), 3 h (FAA), or 6 h (DMXAA) before heating. The radiation dose (±95% confidence interval) that controls 50% of treated tumors (the TCD 50 value) was estimated to be 53 Gy (51-55 Gy) for radiation alone. This was decreased to 48 Gy (46-51 Gy), 45 Gy (41-49 Gy), and 42 Gy (39-45 Gy), respectively, by injecting CA4DP, DMXAA, or FAA 30-60 min after irradiating. These values were further decreased to around 28-33 Gy if the tumors of VTA-treated mice were also heated to 41.5 degree sign C for 1 h, starting 4 h after irradiation, and this effect was much larger than the enhancement seen with either 41.5 degree sign C or even 43 degree sign C alone. Conclusions: Our preclinical studies and those of others clearly demonstrate that VTAs can enhance tumor response to hyperthermia and/or radiation and support the concept that such combination studies should be undertaken clinically for the full potential of VTAs to be realized

    Selective mutism (SM) is a debilitating childhood anxiety disorder characterized by a persistent lack of speech in certain social settings and is considered hard to treat. Cognitive behavioral therapy (CBT) and pharmacological treatments are the best described treatments in the literature. To test whether there is evidence on treatment based on CBT, medication or a combination of these. Systematic and critical review of the literature on CBT and/or pharmacological treatments of SM. Literature was sought on PubMed, Embase and Psycinfo in March 2017. Of the included studies, six examined CBT, seven pharmacologic treatment and two a combination of these. Using CBT 53/60 children improved symptomatically whilst respectively 55/67 and 6/7 improved using pharmacologic- and combination-treatment. Pharmacologic treatment and especially CBT showed promising results supported by some degree of evidence, which combination treatment lacks. Yet small numbers, few RCTs, heterogeneous study designs, lack of consistent measures, short treatment and follow-up periods, generally limits the evidence. This needs focus in future research.

Three historical eras followed the exclusive clinical approach of the 19th century. At the turn of the century, the “initial research” era was initiated because of the dramatic spread of HAT throughout intertropical Africa, and scientists discovered the agent and its vector. Two entities, recurrent fever and sleeping sickness, were then considered a continuum between hemolymphatic stage 1 and meningoencephalitic stage 2. Treatments were developed. Soon after World War I, specific services and mobile teams were created, initiating the “epidemiological” era, during which populations were visited, screened, and treated. As a result, by 1960, annual new cases were rare. New mass screening and staging tools were then developed in a third, “modern” era, especially to counter a new epidemic wave. Currently, diagnosis still relies on microscopic detection of trypanosomes without (wet and thick blood films or with concentration techniques (capillary tube centrifugation, miniature anion-exchange centrifugation technique. Staging is a vital step.Stage 1 patients are treated on site with pentamidine or suramin. However, stage 2 patients are treated in specialized facilities, using drugs that are highly toxic and/or that require complex administration procedures (melarsoprol, eflornithine, or nifurtimox-eflornithine combination therapy. Suramin and melarsoprol are the only medications active against Rhodesian HAT. Staging still relies on cerebrospinal fluid examination for trypanosome detection and white blood cell counts: stage 1, absence of trypanosomes, white blood cell counts ≤ 5/µL; stage 2, presence of

    Nanomedicine of synergistic drug combinations has shown increasing significance in cancer therapy due to its promise in providing superior therapeutic benefits to the current drug combination therapy used in clinical practice. In this article, we will examine the rationale, principles, and advantages of applying nanocarriers to improve anticancer drug combination therapy, review the use of nanocarriers for delivery of a variety of combinations of different classes of anticancer agents including small molecule drugs and biologics, and discuss the challenges and future perspectives of the nanocarrier-based combination therapy. The goal of this review is to provide better understanding of this increasingly important new paradigm of cancer treatment and key considerations for rational design of nanomedicine of synergistic drug combinations for cancer therapy.

    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.

    Objective. Binge eating disorder is a serious, prevalent eating disorder that is associated with overweight. Zonisamide is an antiepileptic drug that can promote weight loss. We evaluated the efficacy and safety of zonisamide as augmentation to individual cognitive behavioral therapy in the treatment of binge eating disorder patients. Design: controlled open study. Participants: Twenty four threshold and subthreshold binge eating disorder patients were enrolled in the cognitive behavioral therapy treatment group, and 28 patients in the cognitive behavioral therapy plus zonisamide group. Measurements: At the beginning (T0), at the end (T1) of treatment, and one year after the end of treatment (T2), body mass index was measured and Eating Disorder Examination-Questionnaire, Binge Eating Scale, Beck Depression Inventory, and State-Trait Anxiety Inventory were administered. Results. At T1 the cognitive behavioral therapy plus zonisamide group showed a higher mean reduction of body mass index, Eating Disorder Examination-Questionnaire, Beck Depression Inventory, and Binge Eating Scale scores. At T2, the cognitive behavior therapy group regained weight, while the cognitive behavioral therapy plus zonisamide group reduced their body mass and showed a higher reduction in binge eating frequency and Binge Eating Scale, Eating Disorder Examination-Questionnaire Restraint, and State and Trait Anxiety Inventory scores. Conclusion. The zonisamide augmentation to individual cognitive behavior therapy can improve the treatment of binge eating disorder patients, reducing body weight and the number of binge eating episodes. These results are maintained one year after the end of treatment. PMID:20049147

    Aldosterone levels increase in 30%-40% of patients on angiotensin-converting enzyme inhibitors and/or angiotensin receptor blockers over the long term. This "aldosterone breakthrough" may carry important clinical consequences given aldosterone's nonepithelial, pro-fibrotic actions. The renin inhibitor, aliskiren, by suppressing the renin-angiotensin-aldosterone system (RAAS) proximally, may limit breakthrough compared to conventional RAAS blockade. This open-label study (NCT01129557) randomized subjects to aliskiren 300 mg daily (A), valsartan 320 mg daily (V), or aliskiren 150 mg + valsartan 160 mg daily (A+V) for 9 months. Eligible subjects had proteinuria >300 mg/day, estimated glomerular filtration rate (eGFR) >45 mL/min/1.73 m(2), and systolic blood pressure (BP) >130 or diastolic BP >80 mm Hg. Serum and 24-hour urine aldosterone (indexed to 24-hour urine Na) were checked before initiation of therapy and at 3, 6, and 9 months. Aldosterone breakthrough was defined as a sustained increase from baseline aldosterone by study end. The study was intended to enroll 120 subjects but was terminated early by the sponsor. We present here the results of 33 subjects who completed the protocol, of which 12 were randomized to A, 11 were randomized to V, and 10 were randomized to A+V. Mean baseline eGFR was 75.5 (±23.3) mL/min/1.73 m(2); baseline proteinuria was 3104 (±2943) mg/day; and baseline BP was 134.7 (±10.5)/84.8 (±8.4) mm Hg. Three (27%) subjects on V, three (25%) subjects on A, and three (30%) subjects on A+V had aldosterone breakthrough. Mean proteinuria reduction was 31% from baseline in all subjects: 30% in subjects with breakthrough vs. 32% in subjects without breakthrough. Mean BP reduction was 11.0/8.8 mm Hg in all subjects: 8.4/6.1 mm Hg in subjects with breakthrough vs. 12.0/9.8 mm Hg in subjects without breakthrough. Aliskiren, alone or in combination with valsartan, did not reduce the incidence of aldosterone breakthrough in subjects with hypertension

    Dexa-Scheroson and Primobolan-Depot were used together with radiation therapy (Linac therapy) required in 13 cases. The following results were obtained. The decrease in white cell counts, which often occurs in radiation therapy, was inhibited by the drugs. There was no case in which radiation therapy should necessarily withdraw because the number of leuckocytes was decreased to less than 3,000. The patients whose liver function was poor should be treated with both drugs at the beginning of radiation therapy. It was found that the combined use of the drugs is effective in the prevention and the treatment of cerebral edema in radiation therapy of intracranial lesion.

    The purpose of the research was to compare the effectiveness of the following treatment methods for fear of flying: cognitive behavioral therapy (CBT) integrated with systematic desensitization, CBT combined with eye movement desensitization and reprocessing therapy, and CBT combined with virtual reality exposure therapy. Overall, our findings have proven the efficacy of all interventions in reducing fear of flying in a pre- to post-treatment comparison. All groups showed a decrease in flight anxiety, suggesting the efficiency of all three treatments in reducing self-report measures of fear of flying. In particular, our results indicated significant improvements for the treated patients using all the treatment programs, as shown not only by test scores but also by participation in the post-treatment flight. Nevertheless, outcome measures maintained a significant effect at a 1-year follow-up. In conclusion, combining CBT with both the application of eye movement desensitization and reprocessing treatment and the virtual stimuli used to expose patients with aerophobia seemed as efficient as traditional cognitive behavioral treatments integrated with systematic desensitization.

    The Polycosanol, a mixture of superior primary aliphatic alcohols obtained from the sugarcane wax (Sacharum officinarum, L.) and the grape seeds extract (Vitis vinifera, L.) produces antioxidant effects experimentally and clinically demonstrated. The aim of present paper was to compare the effects of Polycosanol, the grape seed extract, and its combined therapy on oxidative markers in plasma and liver of rats. The rats were distributed into 4 groups: a control one and three treated with Polycosanol, grape seed extract and its combined therapy, respectively, using a 25 mg/kg dose over 4 weeks. The single-therapies significantly reduced the plasmatic concentrations of malonyldialdehyde and of protein-associated carbonyl groups regarding the control, showing a similar efficacy. Combined therapy reduced in a more effective way (p < 0,001) the malonyldialdehyde concentrations of carbonyl groups, and also decreased (p < 0,01) the concentrations of carbonyl groups, but no more than the single-therapies. Each single-therapy reduced the malonyldialdehyde concentrations generated by spontaneous oxidant system in liver homogenate. The effect of combined therapy was higher (p < 0,05) than the grape seed extract, but no more than that of polycosanol. We concluded that oral single-therapies using polycosanol and grape seed extract, administered during 4 weeks, decreased in a similar way, the lipid peroxidation in plasma and liver of rats. Combined therapy was more effective to inhibits the lipid peroxidation in plasma than each single-therapy, separately

    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.

    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

    Purpose: To determine the rate of tumor response and patterns of relapse following combined hormonal-radiation therapy of adenocarcinoma of the prostate and to measure the survival in a group of men with tumor metastatic to pelvic lymph nodes. Methods and Materials: 66 patients with adenocarcinoma of the prostate with pathologically confirmed pelvic lymph node involvement were treated with combined radiation therapy and hormonal therapy. An additional five patients declined hormonal therapy. The patients treated with combined therapy represented a group with locally advanced disease including 44 patients (67%) with T3 or T4 tumors and 51 patients (80%) had N2 or N3 lymph node metastases. The pelvic lymph nodes were treated to a dose of 45 Gy and the prostate was boosted to a dose of 65 to 71 Gy. Hormonal therapy began up to 2 months before radiation and continued indefinitely. Patients were allowed to select their hormonal therapy and could choose DES (2 patients), orchiectomy (21 patients), LHRH agonist (7 patients) or combined androgen blockade (34 patients). Results: Median follow-up is 49 months (range 12 to 131 months) and 21 patients have been followed for longer than 5 years. There have been 15 recurrences the entire group including three local recurrences in the prostate, seven patients with distant metastases, four patients with biochemical recurrences without clinical evidence of disease, and one patient where the location was unknown. Two of the PSA recurrences occurred in patients who elected to discontinue hormones after less than 3 years of therapy. The overall survival at 5 and 8 years is 94 and 84%, the clinical disease free survival is 85 and 67%, and the biochemical disease-free survival is 78 and 47%. There was no increased toxicity of the combined modality regimen compared to the expected effects of radiation and hormonal therapy. Conclusion: Combined hormonal and radiation therapy represents an effective treatment option for patients with

    2014-01-01

    Full Text Available Successful cancer control relies on overcoming resistance to cell death and on activation of host antitumor immunity. Oncolytic viruses are particularly attractive in this regard, as they lyse infected tumor cells and trigger robust immune responses during the infection. However, repeated injections of the same virus promote antiviral rather than antitumor immunity and tumors may mount innate antiviral defenses to restrict oncolytic virus replication. In this article, we have explored if alternating the therapy virus could circumvent these problems. We demonstrate in two virus-resistant animal models a substantial delay in antiviral immune- and innate cellular response induction by alternating injections of two immunologically distinct oncolytic viruses, adenovirus, and vaccinia virus.

    Full Text Available Prevention and treatment of postoperative purulent-inflammatory complications in urological practice remains a subject for study and improvement in all medical centers. The principle of evidence must be taken as a basis of effectiveness of therapy. In this study the quality criteria of demonstrated therapy are immunological parameters.The purpose of this study is to identify the effectiveness of using monooxidase (NO containing a gas stream replenishing the deficiency of endogenous NO in a group of patients; and to investigate immunological reactivity in patients under complex therapy included nitrogen monoxide and immunomodulators.Materials and methods. In this experimental study we determined the functioning of the main links of the patient’s immunological system. They were determined on the basis of the levels of general T-lymphocytes (T-total, T-helper (T-h, T-suppressor (T-s, natural killer (NK, B-lymphocyte and immunoglobulin G, M, A, circulating immune complexes (CIC.Results. Based on the obtained data, we concluded that the traditional treatment of patients with postoperative complications was less effective than the one proposed in our study. Immunological picture of patient’s condition come back to normal almost from the first day of treatment, and under traditional treatment it was only on the 7th day. Under using complex treatment with nitrogen monoxide, parameters of humoral immunity corresponded to the norm already on the 7–14th day from the beginning of treatment.Conclusion. NO-containing gas flow application in complex prevention of purulent-inflammatory complications made possible to eliminate wound infection in shorter terms and to shorten the period of patient’s hospitalization. The best results were obtained in terms of immunological reactivity in a clinical trial in patients who received complex therapy included nitrogen monoxide and lymphotropic administration of the immunomodulators.

    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.

  1. Current concepts in combination therapy for the treatment of hypertension: combined calcium channel blockers and RAAS inhibitors

    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

    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

    A combined therapy of radiation and hyperthermia is said to be fairly effective when applied to certain malignant tumors. However, the utility of this therapy for the treatment of angiosarcoma has not been well discussed. Recently, we have had a chance to treat a patient with metastatic angiosarcoma of the neck by using this combined therapy. In this paper, the clinical course of this patient and the availability of this combined therapy for angiosarcoma is reported. The patient was a 77-year-old man, having a primary lesion on the head and a metastatic tumor over the left cheek and neck. This combined therapy was used for the treatment of the metastatic tumor which caused severe pain and uncontrollable bleeding. The results were considered good ; the tumor decreased in size, pain disappeared and no further bleeding or severe side effects were observed. Though the patient died of another metastatic lesion which could not be treated with this combined therapy because the area of its localization could not allow placement in our hyperthermal apparatus, it is concluded that the combined therapy of radiation and hyperthermia is useful selectively for the treatment for angiosarcoma.

    2000-01-01

    We conducted an experimental study, using a combination of coarse crystal cisplatin and radiotherapy for bone tumors, to evaluate the possibility of the clinical application of chemical embolus therapy in the field of orthopedic surgery. Experimental femoral bone tumors were produced, in rabbits, using VX2 carcinoma. The rabbits were allocated to five groups: untreated control, embolus, chemical embolus, irradiation alone, and chemical embolus and irradiation combination. These therapies were evaluated comparatively, in terms of local antitumor effects (including body weight, X-ray findings, angiography, and histopathology) and in terms of inhibition of pulmonary metastasis. Local antitumor effects, as evaluated by all parameters, except for body weight, were significantly greater for the chemical and irradiation combination group than for the chemical embolus, irradiation alone, untreated control, and embolus groups. There was no significant difference in the inhibition of pulmonary metastasis among the chemical embolus and irradiation combination, chemical embolus, and irradiation alone groups. These findings demonstrated the synergistic effect of the combination of chemical embolus therapy and radiotherapy. In this study, however, no significant difference was found between the chemical embolus therapy alone and the combination therapy groups in the inhibitory effect on pulmonary tumor metastasis, suggesting the need to conduct combination therapy repeatedly in the clinical setting.

    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 question of superiority concerning operative or radiation therapy should not make us forget that the combined therapy of gynaecologic carcinomas was proven to be good. The differing therapy results are due to the problems of classifying the phases, the ages of the patients, the histology, and, not less important, the radiation sensibility of gynaecologic tumours. The psychological and psychosomatic aspects of treating gynaecologic tumours are discussed. (APR) [de

  8. Ethical hot spots of combined individual and group therapy: applying four ethical systems.

    Brabender, Virginia M; Fallon, April

    2009-01-01

    Abstract Combined therapy presents ethical quandaries that occur in individual psychotherapy and group psychotherapy, and dilemmas specifically associated with their integration. This paper examines two types of ethical frameworks (a classical principle-based framework and a set of context-based frameworks) for addressing the ethical hot spots of combined therapy: self-referral, transfer of information, and termination. The principle-based approach enables the practitioner to see what core values may be served or violated by different courses of action in combined therapy dilemmas. Yet, the therapist is more likely to do justice to the complexity and richness of the combined therapy situation by supplementing a principle analysis with three additional ethical frameworks. These approaches are: virtue ethics, feminist ethics, and casuistry. An analysis of three vignettes illustrates how these contrasting ethical models not only expand the range of features to which the therapist attends but also the array of solutions the therapist generates.

    From 496 case reports of patients with a corpus carcinoma collected between 1970 and 1976, the clinical findings, separation into clinical stages and the various therapy forms were compiled and evaluated. As a mean age of 62.3 years, 56.9 per cent of patients reached an average five-year, recidivation-free survival periods. Metastases occurred in 19.1 per cent of all treated women, vaginal recidivations in 1.8 per cent. Particular attention was given to the side effects of radiation therapy and retarded harmful effects. In this connexion an increase in complications following treatment with newly introduced radiation qualities had to be recorded. 21.9 per cent of all radiation-treated patients differed side-effects, and in 11.7 per cent of all radiation-treated women retarded harmful effects were found. Owing to the experience collected meanwhile in radiotherapy with ultra-hard X-rays and to the use of computerized tomography establishing the adequate quantity of radiation, complications following radiation treatment are expected to occur less frequently in future.

    Full Text Available 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 15th 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 impact of antihypertensive treatment on blood pressure (BP) control is fairly unknown. The aim of the study was to evaluate the degree of BP control and its relationship with treatment-related factors in hypertensive patients treated with 2 or 3 agents and attended in referral units. We studied 1,337 hypertensive subjects (41% women) with a mean age (SD) of 63 (12) years, who were receiving 2 or 3 antihypertensive drugs. The degree of BP control was estimated in a single visit by the proportion of patients with BP below 140/90mmHg. BP was controlled in 767 patients (57%). Lack of BP control was related to older age (12% risk for each 10-year increase) and the presence of microalbuminuria (64% risk increase). In those treated with 2 agents, BP control was 61%, without differences between those treated with fixed-drug or free combinations. BP control in those treated with 3 agents was 55%, higher in those receiving 3 agents in a fixed-drug combination (68%) compared with those on 3 agents administered separately (52%; P=.025). Drug classes used in combinations did not influence the degree of BP control. The degree of BP control in patients treated with 2 or 3 agents is 57%. Microalbuminuria is related to a lack of BP control. In those receiving 3 agents, the use of fixed-drug combinations is associated with better BP control. Copyright © 2013 Elsevier España, S.L.U.

    2013-07-01

    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.

  18. Locally advanced cervix carcinoma - innovation in combined modality therapy

    International Nuclear Information System (INIS)

    Swift, Patrick S.

    1996-01-01

    Locally advanced cervical carcinoma continues to be a challenge to the clinician due to local failure as well as systemic metastases. Standard intracavitary and external beam techniques result in local control rates of only 35-65%, with long term survival rates of 25-60% in patients with state IIIA-IVA disease, indicating the need to identify new treatment strategies. Optimization programs for remote-afterloading interstitial brachytherapy allow the delivery of higher local doses of radiation to volumes that more closely approximate tumor target volumes as identified on MR scans, leading to improved therapeutic ratios. Identification of subsets of patients more likely to fail standard therapy, either locally or systemically, may be possible through such techniques as in vivo measurements of hypoxia with Eppendorf oxygen electrodes, interstitial fluid pressure measurements, the Comet assay, and nitroimidazole binding methods. Traditional chemotherapies, administered in either a neoadjuvant role or concomitantly with radiation have been disappointing in prospective trials. A variety of new agents are being investigated to determine if they can increase the frequency or duration of complete response. The taxanes, with response rates of 17-23% by themselves, are being assessed as potential radiosensitizers. The camptotheicin CRT-11 (Irinotecan) has demonstrated activity in platinum resistant cervix cancer, with response rates of 24%. Bioradiotherapeutic approaches, using 13-cis-retinoic acid and interferon-2a, are undergoing phase II studies. Neoangiogenesis inhibitors and vaccines against HPV are also being examined. The aggressive pursuit of techniques that help identify those patients most likely to fail, that allow the delivery of higher radiation doses more safely to the target volume, and that incorporate the use of more effective systemic therapies is necessary to improve the outcome for this disease

    Siemann, D.W.; Hill, S.A.

    1984-01-01

    Studies were performed to determine whether the radiation sensitizer misonidazole (MISO) could enhance the tumor control probability in a treatment strategy combining radiation and the nitrosourea 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU). In initial experiments KHT sarcoma-bearing mice were injected with 1.0 mg/g of MISO simultaneously with a 20 mg/kg dose of CCNU 30-40 min prior to irradiation (1500 rad). With this treatment protocol approximately 60% of the mice were found to be tumor-free 100 days post treatment. By comparison all 2 agent combinations led to 0% cures. To evaluate the relative importance of chemopotentiation versus radiosensitization in the 3 agent protocol, tumors were treated with MISO plus one anti-tumor agent (either radiation of CCNU) and then at times ranging from 0 to 24 hr later exposed to the other agent. When the time between treatments was 0 to 6 hr, a 60 to 80% tumor control rate was achieved for both MISO plus radiation followed by CCNU and MISO plus CCNU followed by radiation. However if the time interval was increased to 18 or 24 hr, the cure rate in the former treatment regimen dropped to 10% while that of the latter remained high at 40%. The data therefore indicate that (1) improved tumor responses may be achieved when MISO is added to a radiation-chemotherapy combination and (2) MISO may be more effective in such a protocol when utilized as a chemopotentiator

    2015-01-01

    Combined therapy of ovarian cancer has a long history. It has been applied for many years. The first drug which was commonly combined with other chemotherapeutics was cisplatin. It turned out to be effective given together with alkylating agents as well as with taxanes. Another drug which is often the basis of first-line therapy is doxorubicin. The use of traditional chemotherapy is often limited due to side effects. This is why new drugs, targeted specifically at cancer cells (e.g. monoclonal antibodies or epidermal growth factor receptor inhibitors), offer a welcome addition when used in combination with conventional anticancer agents. Drugs applied in combination should be synergistic or at least additive. To evaluate the type of interaction between drugs in a plausible sequence, isobolographic analysis is used. This method allows one to assess whether the two agents could make an efficient combination, which might improve the therapy of ovarian cancer.

    1983-01-01

    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. (Chiba, N.)

    Several risk factors such as abnormality of lipid metabolism (e.g. high levels of low-density lipoprotein cholesterol (LDL-C), elevated triglycerides and low levels of high-density lipoprotein cholesterol (HDL-C)) play a central role in the aetiology of cardiovascular disease (CVD). Nutraceutical combination together with a cholesterol- lowering action, when associated with suitable lifestyle, should furnish an alternative to pharmacotherapy in patients reporting statin-intolerance and in subjects at low cardiovascular risk. The present review is focused on nutraceuticals and their synergetic combinations demonstrating a beneficial effect in the management of dyslipidaemia. Several nutraceuticals have been shown to positively modulate lipid metabolism having different functions. Plant sterols and soluble fibres can, for example, decrease the intestinal assimilation of lipids and increase their elimination. Furthermore, berberine and soybean proteins improve the cholesterol uptake in the liver. Policosanols, monacolins and bergamot inhibit hydroxy-methyl-glutaryl coenzyme A reductase (HMGCoA reductase) enzyme action determining the cholesterol hepatic synthesis. Moreover, pomegranate can decrease LDL oxidation and positively affect subclinical atherosclerosis; red yeast rice and berberine play, instead, an important role on endothelial dysfunction and psyllium, plant sterols and bergamot have positive effects on LDL subclasses. To the best of our knowledge, there are no long-term large-scale studies on the anti-atherogenic effect of the nutraceuticals that are available on the market. Thus, further clinical studies should investigate in order to achieve long term tolerability and safety and to provide a better nutraceutical combination tailored to the patient needs.

    2016-11-01

    Full Text Available 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 (CTLA-4 and programmed death-1 (PD-1 emerged as promising strategies to activate anti-tumor 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, aimed at increasing response-rates to the single treatments.

    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.

TCC had to be applied daily at night for two months by group A patients while group B was consigned for IPL therapy fortnightly, and those in group C were given both for two months. Efficacy was compared by recalculating MASI score at treatment end as well as at follow-up after 4 weeks, using Chi-square test with significance at p < 0.05. Results:Male and female patients were 10 (31.2%) and 22 (68.8%) in group A, 7 (21.9%) and 25 (78.1%) in group B, while in group C were 12 (37.5%) and 20 (62.5%). The average age was 28.70 +8.70 years. MASI score reduction was achieved in 22 (68.8%) patients in group A; whereas, in 20 (62.5%) and 30(93.8%) patients in group B and C, respectively. Efficacy-wise distribution was significant (p=0.009). Conclusion:Intense pulse light therapy and triple combination cream are more efficacious in epidermal melasma treatment than intense pulse light therapy and triple combination cream alone. (author)

    Microenvironmental acidity is becoming a key target for the new age of cancer treatment. In fact, while cancer is characterized by genetic heterogeneity, extracellular acidity is a common phenotype of almost all cancers. To survive and proliferate under acidic conditions, tumor cells up-regulate proton exchangers and transporters (mainly V-ATPase, Na⁺/H⁺ exchanger (NHE), monocarboxylate transporters (MCTs), and carbonic anhydrases (CAs)), that actively extrude excess protons, avoiding intracellular accumulation of toxic molecules, thus becoming a sort of survival option with many similarities compared with unicellular microorganisms. These systems are also involved in the unresponsiveness or resistance to chemotherapy, leading to the protection of cancer cells from the vast majority of drugs, that when protonated in the acidic tumor microenvironment, do not enter into cancer cells. Indeed, as usually occurs in the progression versus malignancy, resistant tumor clones emerge and proliferate, following a transient initial response to a therapy, thus giving rise to more malignant behavior and rapid tumor progression. Recent studies are supporting the use of a cocktail of proton exchanger inhibitors as a new strategy against cancer.

    Full Text Available Interventional therapy has become the first choice of non-surgical treatment for hepatocellular carcinoma (HCC due to its advantages such as little trauma and marked local effect. However, the clinical efficiency is less than expected. One of the possibilities is the resistance of cancer cells to anti-cancer drugs. Increasing attention has been paid to the combination of traditional Chinese medicine (TCM and interventional therapy in HCC treatment. This paper reviews the progress in TCM combined with interventional therapy for HCC at animal experiment and clinical study levels in recent ten years. It is pointed out that the combination therapy with TCM and intervention for HCC has a unique advantage.

    Objective: To explore the anti-tumor effects of Egr-IFNγ gene therapy combined with 125 I-UdR radionuclide therapy in mice bearing H22 hepatocarcinoma and its mechanism. Methods: The recombinant plasmid pcDNAEgr-IFNγ mixed with liposome was injected into tumor. 48 h later, 370 kBq 125 I-UdR was injected into tumor. The tumor growth rates at different times were observed. After 3 d gene-radionuclide therapy, the concentration of IFNγ in cytoplasm of H22 cells and cytotoxic activities of splenic CTL of the mice in different groups were examined. Results: The tumor growth rates of pcDNAEgr-IFNγ + 125 I-UdR group were obviously lower than those of control group, 125 I-UdR group and pcDNAEgr-1 + 125 I-UdR group 6-15 d after gene-radionuclide therapy. IFNγ protein was found in cytoplasm of H22 cells in pcDNAEgr-IFNγ + 125 I-UdR group after 3 d gene-radionuclide therapy. Cytotoxic activity of splenic CTL in pcDNAEgr-IFNγ + 125 I-UdR group was significantly higher than that in the other groups (P 125 I-UdR radionuclide therapy are better than those of 125 I-UdR therapy.

    Ten patients with histologically confirmed inoperable malignant mesothelioma of the pleura were treated with doxorubicin and fractionated radiotherapy courses. Three patients derived significant clinical benefit from this treatment, although only one of the three had measureable tumor shrinkage that could be defined as partial response. Two of the ten patients showed only progressive disease, while the remaining five showed disease stabilization for 30--100 weeks. The treatment was subjectively well-tolerated and hematopoietic toxicity was acceptable. Radiation pneumonitis did not occur. Two of the four patients who lived greater than or equal to 94 weeks developed fibrosis of the irradiated hemithorax. The median survival time for all patients was 46 weeks. Although the combined treatment could be given with acceptable toxic effects and although four patients benefited from it, the best objective assessment, namely, survival time, did not appear to be adequately influenced to justify an extension of this series

  10. 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.

  11. Combined Immune Therapy for the Treatment of Visceral Leishmaniasis.

    Full Text Available 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 silver-based dressings with negative pressure therapy after radical excision of chronically infected breast disease is a novel application of two technologies. One patient with complex, chronic, infected breast disease underwent radical excision of the affected area and was treated early with a combination of silver-based dressings and topical negative pressure therapy. The wound was then assessed sequentially using clinical measurements of wound area and depth, pain severity scores and level of exudation. It is possible to combine accepted techniques with modern dressing technologies that result in a positive outcome. In this case, the combination of a silver-based dressing with negative pressure therapy following radical excision proved safe and was well tolerated by the patient. Full epithelisation of the wound was achieved and there was no recurrence of the infection for the duration of the treatment. © 2011 The Authors. © 2011 Blackwell Publishing Ltd and Medicalhelplines.com Inc.

    The paper is concerned with immunological evaluation of different stages of combined therapy with local UHF-hyperthermia in children with osteogenic sarcoma. Combined therapy (polychemo- and raditherapy) was shown to cause a decrease in the number of immunocompetent cells, to enhance dysbalance of immunoregulatory T-lymphocytes, to weaken T-lymphocyte function on PHA; immunosuppressive action of combined therapy did not depend on a tumor site. The incorporation of UHF-hyperthermia in the therapeutic scheme weakened the manifestations of secondary immunodeficiency, got back to normal structure of T-lymphocyte population. A favorable immunomodulating effect of hyperthermia was more frequently observed in patients with crural bone tumors. The effect of hyperthermia was revealed after direct influence of thermotherapy but it was absent in continuation of combined treatment

    This study aims to evaluate the efficacy of Methotrexate (MTX) alone and combined therapy with Etanercept (ETN) and Methotrexate in patients with active rheumatoid arthritis (RA). In the randomised control study, conducted in the period from March 2014 until March 2016, we evaluated the efficacy of the treatment of patients with RA with MTX as monotherapy and combination treatment with MTX and ETN. In the Clinic of Rheumatology in Prishtina, 90 adult patients with RA were treated in combination with ETN (doses of 50 mg subcutaneously/weekly), with oral MTX (doses up to 20 mg weekly), and MTX alone (doses up to 20 mg weekly) during this period of two years. Clinical response was assessed using European League against Rheumatism (EULAR)/American College of Rheumatology (ACR) Criteria and the Disease Activity Score (DAS28). Radiographic changes were measured in the beginning and at the end of the study using Larsen's method. Of the cohort groups of 90 patients, mean age of 55.63, 15 patients, (16.6 %) were treated with combined therapy (ETN plus MTX) and 75 patients (83.3%) with monotherapy (MTX). After two years of treatment the group with combined therapy resulted with improvement of acute phase reactants as erythrocyte sedimentation rate (ESR) for the first hour (41.1 vs. 10.3 mm/hour) and C - reactive protein (CRP) (40.8 vs. 6 mg/liter), and compared to the group treated with monotherapy, there were no significant changes (ESR: 45.7 vs 34.3 mm/hour; CRP: 48 vs 24 mg/liter). Before the treatment, the severity of the disease was high, wherein the group with combined therapy DAS28 was 5.32, compared to the monotherapy group whom DAS28 was 5.90. After 2 years of treatment, we had significant changes in the results of DAS28, wherein the group treated with ETN plus MTX DAS28 was 2.12 ± 0.15, while in the group of patients treated with MTX DAS28 were 3.75 ± 0.39 (t = 13.03; df = 58; p < 0.0001). The group with combined therapy showed no evidence of radiographic

    The spread of carbapenemase-producing K. pneumoniae (CPKP) has become a significant problem worldwide. Combination therapy for CPKP is encouraging, but polymyxin resistance to many antibiotics is hampering effective treatment. Combination therapy with three or more antibiotics is being increasingly reported, therefore we performed a systematic review of triple combination cases in an effort to evaluate their clinical effectiveness for CPKP infections. The PubMed database was searched to identify all published clinical outcomes of CPKP infections treated with triple combination therapy. Articles were stratified into two tiers depending on the level of clinical detail provided. A tier 1 study included: antibiotic regimen, regimen-specific outcome, patient status at onset of infection, and source of infection. Articles not reaching these criteria were considered tier 2. Thirty-three studies were eligible, 23 tier 1 and ten tier 2. Among tier 1 studies, 53 cases were included in this analysis. The most common infection was pneumonia (31%) followed by primary or catheter-related bacteremia (21%) and urinary tract infection (17%). Different combinations of antibiotic classes were utilized in triple combinations, the most common being a polymyxin (colistin or polymyxin B, 86.8%), tigecycline (73.6%), aminoglycoside (43.4%), or carbapenem (43.4%). Clinical and microbiological failure occurred in 14/39 patients (35.9%) and 22/42 patients (52.4%), respectively. Overall mortality for patients treated with triple combination therapy was 35.8% (19/53 patients). Triple combination therapy is being considered as a treatment option for CPKP. Polymyxin-based therapy is the backbone antibiotic in these regimens, but its effectiveness needs establishing in prospective clinical trials.

    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.

    Radiation accidents of the 5-7 th levels according to IAEA scale lead to life-threatening acute radiation syndrome and many patients will probably suffer from additional thermal burns. These combined injuries (CI) will be among the most difficult to achieve survival. Present therapeutic means need to augment with new approaches to stimulate host defence mechanisms, blood system recovery and to enhance survival. The evaluation of therapeutic properties of human recombinant G-CSF, IL-1,IL-2 and other so called 'biological response modifiers' on survival and blood recovery after CI was the purpose of this work. Experiments carried out with mice CBA x C57BL6 receiving 7 Gy total body irradiation followed by a full-thickness thermal bum of 10% of body surface. It established that G-CSF does not exhibit a positive modifying action on the damage level and on hematopoietic recovery. I.p two-four/fold infusion of IL-2 during the initial 2 days has provided a significant statistically survival increase from 40% (untreated mice with CI) to 86%. Single s.c IL-1 injection resulted in abrupt deterioration of the outcome when dealing with CI; three/fold administration of IL-1 in 2,4 and 6 days after CI did not increase survival. Extracellular yeast polysaccharides resulted only a 15 to 30% increase in survival it given 1 h after CI. The best results obtained when mixture of heat-killed L.acidophilus injected s.c immediately alter CI - survival has increased from 27% (untreated mice) to 80%. Revealed beneficial effects of IL-2 and biological response modifiers did not accompany by a corresponding correction of depressed hematological parameters

    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.

    Intravenous enzyme replacement therapy is a first-line therapy for Gaucher disease type 1, and substrate reduction therapy represents an oral treatment alternative. Both enzyme replacement therapy and substrate reduction therapy are generally used as monotherapies in Gaucher disease. However, one randomized study and several case reports have described combination therapy over short time periods. We report two female Gaucher disease type 1 patients of mainly Anglo-Saxon descent, where combined enzyme replacement therapy and miglustat substrate reduction therapy were administered to overcome refractory clinical symptoms. The first patient was diagnosed at age 17 and developed Gaucher disease-related bone manifestations that worsened despite starting imiglucerase enzyme replacement therapy. After switching to miglustat substrate reduction therapy, her bone symptoms improved, but she developed tremors and eventually switched back to enzyme replacement therapy. Miglustat was later recommenced in combination with ongoing enzyme replacement therapy due to continued bone pain, and her bone symptoms improved along with maintained visceral manifestations. Enzyme replacement therapy was subsequently tapered off and the patient has since been successfully maintained on miglustat. The second patient was diagnosed aged 3, and commenced imiglucerase enzyme replacement therapy aged 15. After 9 years on enzyme replacement therapy she switched to miglustat substrate reduction therapy and her core symptoms were maintained/stable for 3 years. Imiglucerase enzyme replacement therapy was later added as a boost to therapy and her symptoms were subsequently maintained over a 2.3-year period. However, miglustat was discontinued due to her relocation, necessitating an increase in enzyme replacement therapy dose. Overall, both patients benefited from combination therapy. While the majority of Gaucher disease type 1 patients will not need treatment with both substrate reduction therapy

    Full Text Available 2-Methoxyestradiol (2-ME has potent anti proliferative effects on cancer cells. Its utility alone or in combination with other therapies for treating prostate cancer, however, has not been fully explored. Androgendependent, independent human prostate cancer cells were examined in vivo for their response to combination therapy. Efficacy was assessed by terminal deoxynucleotide transferase-mediated dUTP nick-end labeling assay, measuring microvessel density (MVD in excised tumors. Animals harboring hormonedependent tumors treated with 2-ME alone, androgen deprivation therapy alone, or the combination of the two had a 3.1-fold, 5.3-fold, 10.1-fold increase in apoptosis, respectively. For hormone-independent tumors, treatment with 2-ME resulted in a 2.43-fold increase in apoptosis, a 73% decrease in MVD. 2-ME was most effective against hormone-dependent tumors in vivo, combination therapy resulted in a significant increase in efficacy compared to no treatment controls, trended toward greater efficacy than either 2-ME or androgen deprivation alone. Combination therapy should be investigated further as an additional therapeutic option for early prostate cancer.

    The metabolic syndrome is strongly associated with insulin resistance and has been recognized as a cluster of risk factors for cardiovascular disease. Insulin resistance and/or impaired early-phase insulin secretion are major determinants of postprandial hyperglycemia. In this study, we investigated the potential utility of combination therapy with telmisartan, an angiotensin II receptor blocker and nateglinide, a rapid-onset/short-duration insulinotropic agent, for the treatment of postprandial hyperglycemia and metabolic derangements in Zucker Fatty (ZF) rats. ZF rats fed twice daily were given vehicle, 50 mg/kg of nateglinide, 5 mg/kg of telmisartan, or both for 6 weeks. Combination therapy with nateglinide and telmisartan for 2 weeks ameliorated postprandial hyperglycemia in ZF rats fed twice daily. Furthermore, 6-week treatment with nateglinide and telmisartan not only decreased fasting plasma insulin, triglycerides, and free fatty acid levels, but also improved the responses of blood glucose to insulin and subsequently reduced the decremental glucose areas under the curve in the ZF rats. Combination therapy also restored the decrease of plasma adiponectin levels in the ZF rats. Monotherapy with nateglinide or telmisartan alone didnot significantly improve these metabolic parameters. These observations demonstrate that combination therapy with nateglinide and telmisartan may improve the metabolic derangements by ameliorating early phase of insulin secretion as well as insulin resistance in ZF rats fed twice daily. Our present findings suggest that the combination therapy with nateglinide and telmisartan could be a promising therapeutic strategy for the treatment of the metabolic syndrome.

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

    A new multimodality therapy, radio-hyperthermo-chemotherapy, has been performed in a total of 31 pancreatic cancer patients with the purpose of improving treatment outcome. Combination of hyperthermia and chemotherapy was given as a pre-irradiation therapy in 7 resectable cancer patients. Among 24 unresectable cancer patients, 17 had irradiation in combination with hyperthermia and chemotherpay. Although both degeneration and necrosis of cancer cells were observed in all resectable cases at biopsy, these were not predictive of a better outcome. Of evaluable 17 patients with unresectable cancer, tumor regression was observed in 5 (29.4%). Although 22 patients had pain before therapy, 8 and 5 patients had remarkable and moderate pain relief, respectively, with therapy. Performance status was improved in 7 patients (29.2%). Survival rate at 12 months was still low (8.3%). However, the radio-hyperthermo-chemotherapy appears to help in increasing the quality of life in view of pain relief. (N.K.)

    Type 2 diabetes is characterized by decreases in insulin secretion and insulin sensitivity. Several classes of oral antidiabetic medications are currently approved for the treatment of type 2 diabetes. A stepwise treatment approach from monotherapy to combination therapy is traditionally used; however, the frequency of treatment failure with monotherapy has resulted in a move towards earlier treatment with combination therapies that target the two principal defects in glycaemic control. One such combination regimen is repaglinide (a prandial glucose regulator that increases insulin release) plus metformin (an insulin sensitizer that inhibits hepatic glucose output, increases peripheral glucose uptake and utilization and minimizes weight gain). Findings from several clinical trials have shown that combination therapy with repaglinide plus metformin is well tolerated and results in greater reductions of haemoglobin A(1c) and fasting plasma glucose values compared with either monotherapy. Repaglinide may also provide a more suitable alternative to combination therapy with sulphonylureas and metformin because of its reduced propensity for hypoglycaemia. The combination regimen of repaglinide plus metformin should therefore be considered as a valuable option in the management of patients with type 2 diabetes when monotherapy is no longer adequate.

    Full Text Available Aim: the study of the efficacy of methotrexate in patients with the "escape effect" during the ustekinumab therapy. Materials and Methods. The results of methotrexate at a dose of 15-20mg/week in treatment of 4 patients receiving biologic and developed "escape effect". Ustekinumab is used as a hypodermic injection at a dose of 45 mg for a body weight of a patient no more than 100 kg, and 90 mg of body weight over 100 kg, at the zero week, the 4th week and then every 12 weeks. 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.

    Both acitretin and methotrexate are effective in ameliorating psoriatic lesion. However, their combination has been seldom reported in the treatment of psoriasis because of the warning regarding the potential hepatotoxicity of the drug interactions. This study was designed to investigate the effectiveness of such combination therapy for psoriasis vulgaris, and the potential benefit as well as side effect during the treatment. Thirty-nine patients with psoriasis vulgaris were treated with acitretin, methotrexate or their combination or as control. Similarly, K14-VEGF transgenic psoriasis-like mice were treated with these drugs. Human primary keratinocytes and hepatic stellate cells were used for analyzing their effect in vitro. The results showed that the combination therapy exhibited higher effectiveness in remitting skin lesion, but did not significantly affect the liver function of both patients and mice. Moreover, the combination groups showed less elevation of profibrotic factors in sera when compared with methotrexate alone groups accordingly. Furthermore, primary keratinocytes expressed more involucrin as well as loricrin and proliferated more slowly on the combined stimulation. Interestingly, such combination treatment induced lower expression of profibrotic factors in hepatic stellate cells. In conclusion, the acitretin-methotrexate combination therapy for psoriasis vulgaris can achieve higher effectiveness and result in less liver fibrosis. Copyright © 2017 Elsevier Ltd.

    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.

    Recent advances in bioengineering have introduced materials that enhance wound healing. Even with such new tools, some deep ulcers surrounded by avascular tissues, including bone, tendon, and fascia, are resistant to various therapies and easily form deep cavities with loss of subcutaneous tissue. Atelocollagen sponges have been used as an artificial dermis to cover full-thickness skin defects. Topical recombinant human basic fibroblast growth factor has been introduced as a growth factor to induce fibroblast proliferation in skin ulcers. We applied these materials in combination in two patients with deep resistant wounds: one with a cavity reaching the mediastinum through a divided sternum and one with deep necrotic wounds caused by electric burns. These wounds did not respond to the topical basic fibroblast growth factor alone. In contrast, the combination therapy closed the wounds rapidly without further surgical treatment. This combination therapy is a potent treatment for resistant wounds with deep cavities.

    Several histone deacetylase inhibitors including Vorinostat have received FDA approval for the treatment of haematological malignancies. However, data from these trials indicate that Vorinostat has limited efficacy as a monotherapy, prompting the need for rational design of combination therapies. A number of epi-sensitised pathways, including sonic hedgehog (SHH), were identified in AML cells by integration of global patterns of histone H3 lysine 9 (H3K9) acetylation with transcriptomic analysis following Vorinostat-treatment. Direct targeting of the SHH pathway with SANT-1, following Vorinostat induced epi-sensitisation, resulted in synergistic cell death of AML cells. In addition, xenograft studies demonstrated that combination therapy induced a marked reduction in leukemic burden compared to control or single agents. Together, the data supports epi-sensitisation as a potential component of the strategy for the rational development of combination therapies in AML.

    2012-07-01

    Levothyroxine therapy is the traditional lifelong replacement therapy for hypothyroid patients. Over the last several years, new evidence has led clinicians to evaluate the option of combined T(3) and T(4) treatment to improve the quality of life, cognition, and peripheral parameters of thyroid hormone action in hypothyroidism. The aim of this review is to assess the physiological basis and the results of current studies on this topic. We searched Medline for reports published with the following search terms: hypothyroidism, levothyroxine, triiodothyronine, thyroid, guidelines, treatment, deiodinases, clinical symptoms, quality of life, cognition, mood, depression, body weight, heart rate, cholesterol, bone markers, SHBG, and patient preference for combined therapy. The search was restricted to reports published in English since 1970, but some reports published before 1970 were also incorporated. We supplemented the search with records from personal files and references of relevant articles and textbooks. Parameters analyzed included the rationale for combination treatment, the type of patients to be selected, the optimal T(4)/T(3) ratio, and the potential benefits of this therapy on symptoms of hypothyroidism, quality of life, mood, cognition, and peripheral parameters of thyroid hormone action. The outcome of our analysis suggests that it may be time to consider a personalized regimen of thyroid hormone replacement therapy in hypothyroid patients. Further prospective randomized controlled studies are needed to clarify this important issue. Innovative formulations of the thyroid hormones will be required to mimic a more perfect thyroid hormone replacement therapy than is currently available.

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

    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

    Objective: To investigate the synergistic antitumor effects of adenovirus-mediated IL-12 gene therapy in combination with radiotherapy in mice bearing liver cancer. Methods: Balb/c mice bearing liver cancer received the treatment at day 1 with tumor local irradiation (TLI) of 20 Gy or mask irradiation when tumor size reached 0.6-1.0 cm. Within 1 hour after irradiation, adenovirus containing IL-12 gene or PBS was intra-tumor injected once a week. Forty-eight hours after the second injection, IFN-γ levels in sera and the supernatant of cultured spleen cells were assayed by ELISA, CTL activity of spleen cells was measured by 3 H-TdR release assay, and phenotypes of tumor-infiltrating lymphocytes were analysed by immunohistochemical staining. Results: The growth of tumors in animals treated with a combination of IL-12 gene therapy and TLI was inhibited more significantly than those with either single treatment (P + and CD8 + lymphocyte infiltration and tumor-specific cytolytic activities, and the levels of IFN-γ in sera were higher in IL-12 gene therapy and IL-12 gene therapy combined with TLI groups. Conclusion: These results suggest that IL-12 gene therapy combined with radiotherapy is more effective than both single treatment modalities and can induce specific antitumor immuno-response greatly

    Adolescents with anorexia nervosa who have obsessive-compulsive (OC) features respond poorly to family-based treatment (FBT). This study evaluated the feasibility of combining FBT with either cognitive remediation therapy (CRT) or art therapy (AT) to improve treatment response in this at-risk group. Thirty adolescents with anorexia nervosa and OC features were randomized to 15 sessions of FBT + CRT or AT. Recruitment rate was 1 per month, and treatment attrition was 16.6% with no differences between groups. Suitability, expectancy and therapeutic relationships were acceptable for both combinations. Correlations between changes in OC traits and changes in cognitive inefficiencies were found for both combinations. Moderate changes in cognitive inefficiencies were found in both groups but were larger in the FBT + AT combination. This study suggests that an RCT for poor responders to FBT because of OC traits combining FBT with either CRT or AT is feasible to conduct.

    To study the effect of Tadalafil combined with behavior therapy in helping obtain semen from infertile men in whom masturbation has failed. Sixty male infertile patients from whom masturbation had failed to obtain semen were equally assigned to receive Tadalafil combined with behavior therapy (combination group) or Tadalafil only (control group). All the patients took Tadalafil 20 mg orally the night before the day of semen collection by masturbation. Before this procedure, the patients of the combination group practiced masturbation 16 - 24 times at home. The average ages of the patients were (37.0 +/- 5.1) yr and (37.5 +/- 5.2) yr and their IIEF-5 scores were 16.50 +/- 1.25 and 16.90 +/- 1.09 in the combination and the control group, respectively, neither with statistically significant difference between the two groups. Semen was successfully obtained from 9 patients (30.0%) of the combination group and 1 patient (3.33%) of the control group, with statistically significant difference between the two groups (chi2 = 7.680, P masturbation, Tadalafil combined with behavior therapy can significantly increase the success rate of semen collection from the male infertile patients in whom masturbation fails.

    Combining peritoneal dialysis (PD) and hemodialysis (HD) has been common treatment option in Japan. In this retrospective, multicenter, observational study, the clinical characteristics and outcomes of 104 patients (57 ± 11 years, males 72%) who had switched from PD alone to combined therapy with PD and HD were studied. Clinical parameters were measured at baseline and after 3 months of combined therapy. At baseline, urine volume, dialysate-to-plasma ratio of creatinine (D/P Cr), and total Kt/V were 150 ml/day (range: 0-2,000 ml/day), 0.67 ± 0.11, and 1.8 ± 0.4, respectively. During the first 3 months of combined therapy, body weight, urine volume, serum creatinine level, and D/P Cr decreased, whereas hemoglobin levels increased. In patients where PD does not result in acceptable outcomes, combined therapy with PD and HD may have potential benefits in terms of dialysis adequacy and hydration status.

    The variants of neuronopathic Gaucher disease may be viewed as a clinical phenotypic continuum divided into acute and chronic forms. The chronic neuronopathic form of Gaucher disease is characterized by a later onset of neurological symptoms and protracted neurological and visceral involvement. The first-choice treatment for nonneuronopathic Gaucher disease is enzyme replacement therapy with recombinant analogues of the deficient human enzyme glucocerebrosidase. Enzyme replacement therapy has been shown to improve hematological and bone manifestations associated with Gaucher disease, but, as with most proteins, recombinant enzymes cannot cross the blood-brain barrier, which prevents effects on neurological manifestations. Substrate reduction therapy with miglustat (N-butyldeoxynojirimycin) inhibits glucosylceramide synthase, which catalyzes the first step in glycosphingolipid synthesis. Because miglustat can cross the blood-brain barrier, it has been suggested that, combined with enzyme replacement therapy, it might be effective in treating neurological symptoms in patients with neuronopathic Gaucher disease. We report observed effects of combined enzyme replacement therapy and substrate reduction therapy in a 7-year-old Caucasian boy with neuronopathic Gaucher disease who was homozygous for L444P mutations. He had received enzyme replacement therapy from the age of 18 months, and concomitant miglustat treatment was commenced, with dosing according to body surface area uptitrated over 1 month with dietary modifications when he reached the age of 30 months. He experienced mild diarrhea after commencing miglustat therapy, which decreased in frequency/severity over time. His splenomegaly was reduced, and his hematological values and plasma angiotensin-converting enzyme activity normalized. Plasma chitotriosidase also showed substantial and sustained decreases. After 5 years of combination therapy, the patient showed no signs of neurological impairment. This case

    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.

    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.

    Full Text Available Interferon (IFN and ribavirin (RBV combination therapy was previously the standard of care for treatment of hepatitis C virus (HCV genotype 2 infection. But, it often induced hemolytic anemia. In 2014, sofosbuvir (SOF was approved for the treatment of chronic HCV genotype 2 in Japan. SOF/RBV therapy is more effective against genotype 2 than IFN/RBV therapy. We report a case of a 74-year-old woman with chronic HCV genotype 2b infection. She received five treatments including RBV and IFN therapy before SOF was approved and all of them were ineffective. Therapies that included RBV induced severe anemia and led to discontinuation of treatment. With pegylated IFN/RBV therapy, the maximum change in hemoglobin (Hb from baseline was −3.7 g/dL. However, SOF/RBV therapy was effective and she achieved sustained virologic response (SVR with a maximum change in Hb from baseline of only −1.2 g/dL. We also found reticulocyte count was very low during treatment in this case and speculate it was one of the reasons that she developed hemolytic anemia with RBV. In conclusion, SOF/RBV therapy is effective and allowed the patient to achieve SVR. An SOF/RBV regimen is safe and effective for patients who have or are at risk of anemia induced by RBV.

    Combination effect of lentinan with X-ray irradiation on the metastatic mouse tumors, L1210, KLN205 and Lewis lung carcinoma were studied. Combination use of lentinan with X-ray therapy prolonged the life of BDF 1 mice bearing L1210 leukemia in the suitable combination conditions. Combination effects of lentinan with X-ray therapy were also observed on the suppression of the growth of KLN205 squamus cell carcinoma and on the suppression of the metastasis of Lewis lung carcinoma. Especially, in the case that lentinan was administered before or after X-ray local irradiation in the pulmorary metastasis system of Lewis lung carcinoma, a marked suppressin of pulmonary metastasis was observed and 2 to 4 mice among 8 tested mice were tumor free.

    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

    Objective: To investigate the clinical curative effects of 131 I therapy combined with low-dose lithium carbonate for Graves disease. Methods: Patients with Graves disease took lithium carbonate (250 mg, once per day) orally for 5 weeks. Then they were treated with 131 I (doses=3.15 MBq(80 uCi)/g, based on 60%-70% of the thyroid size). We kept track from 6 to 24 months (averaging 14 months) and classified the results into three: cured, improved or no effect. Results: After a single cycle of 131 I therapy combined with low-dose lithium carbonate, 106 patients with Graves disease were cured, 28 were improved and 8 saw no effects, respectively 74.6%, 19.7% and 5.6% among the 142 patients. We then treated 23 of them with another 131 I therapy (without lithium carbonate). 10 of such were cured (43.5%), 8 were improved (34.8%) and the other 5 saw no effects. Among all patients, hypothyroidism was observed from 25(17.6%), 6 months after the first 131 I therapy. Conclusions: Notable curative results were observed from 131 I therapy combined with low-dose lithium carbonate for Graves disease. Moreover, the dosage of 131 I was therefore decreased, which also lowered the toxicity response. (authors)

    The functional connectivity and structural proximity of elements of the language and motor systems result in frequent co-morbidity post brain injury. Although rehabilitation services are becoming increasingly multidisciplinary and "integrated", treatment for language and motor functions often occurs in isolation. Thus, behavioural therapies which promote neural reorganisation do not reflect the high intersystem connectivity of the neurologically intact brain. As such, there is a pressing need for rehabilitation tools which better reflect and target the impaired cognitive networks. The objective of this research is to develop a combined high dosage therapy tool for language and motor rehabilitation. The rehabilitation therapy tool developed, MaLT (Motor and Language Therapy), comprises a suite of computer games targeting both language and motor therapy that use the Kinect sensor as an interaction device. The games developed are intended for use in the home environment over prolonged periods of time. In order to track patients' engagement with the games and their rehabilitation progress, the game records patient performance data for the therapist to interrogate. MaLT incorporates Kinect-based games, a database of objects and language parameters, and a reporting tool for therapists. Games have been developed that target four major language therapy tasks involving single word comprehension, initial phoneme identification, rhyme identification and a naming task. These tasks have 8 levels each increasing in difficulty. A database of 750 objects is used to programmatically generate appropriate questions for the game, providing both targeted therapy and unique gameplay every time. The design of the games has been informed by therapists and by discussions with a Public Patient Involvement (PPI) group. Pilot MaLT trials have been conducted with three stroke survivors for the duration of 6 to 8 weeks. Patients' performance is monitored through MaLT's reporting facility

    Daptomycin β-Lactam combination therapy offers "protection" against daptomycin non-susceptibility (DNS) development in Enterococcus faecium. We report failure of this strategy and the importance of source control. Mutations were detected in the LiaF and cls genes in DNS isolates. A single DNS isolate contained an unrecognized mutation, which requires confirmation. Copyright © 2017 Elsevier Inc. All rights reserved.

    To compare the effectiveness of antimicrobial photodynamic therapy (PDT), standard endodontic treatment and the combined treatment to eliminate bacterial biofilms present in infected root canals. Ten single-rooted freshly extracted human teeth were inoculated with stable bioluminescent Gram-negative bacteria, Proteus mirabilis and Pseudomonas aeruginosa to form 3-day biofilms in prepared root canals. Bioluminescence imaging was used to serially quantify bacterial burdens. PDT employed a conjugate between polyethylenimine and chlorin(e6) as the photosensitizer (PS) and 660-nm diode laser light delivered into the root canal via a 200-micro fiber, and this was compared and combined with standard endodontic treatment using mechanical debridement and antiseptic irrigation. Endodontic therapy alone reduced bacterial bioluminescence by 90% while PDT alone reduced bioluminescence by 95%. The combination reduced bioluminescence by >98%, and importantly the bacterial regrowth observed 24 hours after treatment was much less for the combination (Ptreatment. Bioluminescence imaging is an efficient way to monitor endodontic therapy. Antimicrobial PDT may have a role to play in optimized endodontic therapy. (c) 2006 Wiley-Liss, Inc.

    The effective therapy of small cell lung cancer is the combination of polychemotherapy and radiation treatment. A randomized small cell lung cancer study of 141 patients revealed that with an agressive treatment more than 50 % complete remissions and nearly 90 % complete and partial remissions can be achieved by corresponding selection of patients.

    The authors present an unusual case of small-cell carcinoma of the esophagus, which manifested on double-contrast esophagography as an ulcerated submucosal mass. The lesion underwent dramatic regression after combination chemotherapy and radiation therapy, which has occasionally been used as an alternative to surgery in patients with this rare but aggressive esophageal neoplasm.

  5. Valsartan combination therapy in the management of hypertension – patient perspectives and clinical utility

    The morbidity and mortality benefits of lowering blood pressure (BP) in hypertensive patients are well established, with most individuals requiring multiple agents to achieve BP control. Considering the important role of the renin-angiotensin-aldosterone system (RAAS) in the pathophysiology of hypertension, a key component of combination therapy should include a RAAS inhibitor. Angiotensin receptor blockers (ARBs) lower BP, reduce cardiovascular risk, provide organ protection, and are among the best tolerated class of antihypertensive therapy. In this article, we discuss two ARB combinations (valsartan/hydrochlorothiazide [HCTZ] and amlodipine/valsartan), both of which are indicated for the treatment of hypertension in patients not adequately controlled on monotherapy and as initial therapy in patients likely to need multiple drugs to achieve BP goals. Randomized, double-blind studies that have assessed the antihypertensive efficacy and safety of these combinations in the first-line treatment of hypertensive patients are reviewed. Both valsartan/HCTZ and amlodipine/valsartan effectively lower BP and are well tolerated in a broad range of patients with hypertension, including difficult-to-treat populations such as those with severe BP elevations, prediabetes and diabetes, patients with the cardiometabolic syndrome, and individuals who are obese, elderly, or black. Also discussed herein are patient-focused perspectives related to the use of valsartan/HCTZ and amlodipine/valsartan, and the rationale for use of single-pill combinations as one approach to enhance patient compliance with antihypertensive therapy.

    Forty consecutive patients with small cell carcinoma of the lung were treated with chemotherapy, radiotherapy or both. Of 34 patients treated with chemotherapy, 24 were treated with combination chemotherapy, containing cyclophosphamide vincristine methotrexate and procarbazine, concurrent with small dose radiation therapy (500 cGy/5 fraction) as a chemosensitizer (COMPrt). The response rate to this regimen was 81 % (29 % complete) and the 2 year survival rate was 28.6 %. These results have been superior to other regimens and the toxicity was not see to be any higher. After completion of COMPrt regimen, 10 patients were treated with intrathoracic radiation therapy (average dose 3000 cGy) and 3 recieved surgical treatment. Radiation therapy improved the 2-year survival rate (42.2 %) when compared with those patients who received no radiation therapy (18.2 %). Three patients received surgical treatment were considered to be disease-free for 23, 17, and 9 months respectively, after induction of chemotherapy. (author)

    The aim of the present study was to compare the effects of a galantamine only therapy and a combination therapy with galantamine plus ambulatory cognitive rehabilitation for Alzheimer's disease patients. For this retrospective cohort study, we enrolled 86 patients with Alzheimer's disease, dividing them into two groups - a galantamine only group (group G, n = 45) and a combination with galantamine plus ambulatory rehabilitation group (group G + R, n = 41). The present cognitive rehabilitation included a set of physical therapy, occupational therapy and speech therapy for 1-2 h once or twice a week. We compared the Mini-Mental State Examination and Frontal Assessment Battery for cognitive assessment, and Geriatric Depression Scale, Apathy Scale, and Abe's Behavioral and Psychological Symptoms of Dementia score for affective assessment in two groups over 6 months. The baseline Mini-Mental State Examination score was 20.2 and 18.7 in groups G and G + R, respectively. Other baseline data (Frontal Assessment Battery, Geriatric Depression Scale, Apathy Scale, and Abe's Behavioral and Psychological Symptoms of Dementia) were not different between the two groups. Although group G kept all the scores stable until 6 months of the treatment, the Apathy Scale score showed a significant improvement in group G + R as early as 3 months, followed by the Mini-Mental State Examination and Frontal Assessment Battery improvements at 6 months (*P = 0.04 and *P = 0.02, respectively). The Geriatric Depression Scale and Abe's Behavioral and Psychological Symptoms of Dementia did not show any changes. The combination therapy of galantamine plus ambulatory cognitive rehabilitation showed a superior benefit both on cognitive and affective functions than galantamine only therapy in Alzheimer's disease patients. © 2015 Japan Geriatrics Society.

    Locally advanced prostate cancer (LAPC) is defined as histologically proven T3–4 prostatic adenocarcinoma. In this review, we define the individual roles of radiotherapy (RT), short-term (ST-) and long-term (LT-) androgen deprivation therapy (ADT), and their combination in multimodal therapy for LAPC. Despite limitations in comparing the clinical outcomes among published papers, in the present study, a trend of 10-year clinical outcomes was roughly estimated by calculating the average rates weighted by the cohort number. With RT alone, the following rates were estimated: 87% biochemical failure, 34% local failure (LF), 48% distant metastasis (DM), 38% overall survival (OS), and 27% disease-specific mortality (DSM). Those associated with ADT alone were 74% BCF, 54% OS, and 25% DSM, which appeared to be better than those of RT alone. The addition of ADT to RT produced a notable local and systemic effect, regardless of ST- or LT-ADT. The LF rate decreased from 34% with RT alone to 21% with ST-ADT and further to 15% with LT-ADT. The DM and DSM rates also showed a similar trend among RT alone, RT+ST-ADT, and RT+LT-ADT. The combination of RT+LT-ADT resulted in the best long-term clinical outcomes, indicating that both RT and ADT are important parts of multimodal therapy.

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

    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

    Objective: To evaluate the efficacy and safety of Saccharomyces boulardii Sachets combined with bismuth quadruple therapy for initial Helicobacter pylori ( H . pylori ) eradication. Methods: From March 2014 to March 2015, 240 participants from the third hospital of Hebei medical university with H . pylori infection were recruited and randomized into three groups: Quadruple therapy group received bismuth potassium citrate 220 mg bid + Rabeprazole 10 mg bid + amoxicillin 1 000 mg bid+ furazolidone 100 mg bid for 10 days. Short-term group and long-term group received the same quadruple therapy for 10 days as above, as well as Saccharomyces boulardii Sachets 500 mg bid for 14 days and 28 days, respectively. H . pylori eradication was confirmed by (13)C/(14)C-UBT at least 4 weeks after completion of therapy. And side effects were investigated during the therapy. Results: The H . pylori eradication rates in quadruple therapy, short-term and long-term group were 80%, 87.5% and 87.5% by ITT analysis ( P =0.321) and 92.8%, 94.6% and 95.9% by PP analysis ( P =0.717), respectively. The overall side effect rate and occurrence of diarrhea and abdominal distension were significantly lower in short-term or long-term group as compared with quadruple therapy group( P =0.007, 0.003, 0.004), but there was no significant difference between the two probiotics groups. Conclusions: Both short and long-term Saccharomyces boulardii Sachets reduced the overall side effect rate and occurrence of diarrhea or abdominal distension when combined with bismuth quadruple therapy for initial H . pylori eradication and no difference was observed in efficacy or safety between the two groups.

    Patients with hypothyroidism are increasingly enquiring about the benefit of using combination therapy of levothyroxine (LT4) and liothyronine (LT3) as a potential treatment for hypothyroidism. Combination therapy, however, remains controversial. The purpose of this study was to systematically review available hypothyroidism treatment recommendations from clinical practice guidelines from around the world to identify the consensus regarding combination therapy. Clinical practice guidelines were obtained from searches of PubMed, EMBASE, and MEDLINE, using several combinations of MeSH terms. The search was limited to clinical guidelines in English-language publications, published between January 1, 1990 and May 1, 2015. A quantitative approach was utilized for data synthesis. Thirteen guidelines were identified, including three regarding pregnancy, two regarding pediatric populations and eight regarding adult populations. There were six guidelines from North America, four guidelines from Europe and three guidelines from South America. Twelve of the guidelines were published after 2010. Nine guidelines addressed combination therapy of LT4 plus LT3, and all nine concluded that LT4 therapy alone is the standard of care, with insufficient evidence to recommend widespread combination therapy. Only the 2012 ETA Guidelines and the 2015 BTA Guidelines concluded that combination therapy could be used, although only in certain circumstances and as an experimental treatment. This systematic review illustrates that clinical practice guidelines worldwide do not recommend and do not support routine use of combination LT4 and LT3 therapy to treat hypothyroidism.

    To compare the clinical efficacy on cervical spondylotic radiculopathy between the combined therapy of massage and magnetic-sticking at the auricular points and the simple massage therapy, and conduct the health economics evaluation. Seventy-two patients of cervical spondylotic radiculopathy were randomized into a combined therapy group, and a simple massage group, 36 cases in each one. Finally, 35 cases and 34 cases were met the inclusive criteria in the corresponding groups separately. In the combined therapy group, the massage therapy and the magnetic sticking therapy at auricular points were combined in the treatment. Massage therapy was mainly applied to Fengchi (GB 20), Jianjing (GB 21), Jianwaishu (SI 14), Jianyu (LI 15) and Quchi (LI 11). The main auricular points for magnetic sticking pressure were Jingzhui (AH13), Gan (On12) Shen (CO10), Shenmen (TF4), Pizhixia (AT4). In the simple massage group, the simple massage therapy was given, the massage parts and methods were the same as those in the combined therapy group. The treatment was given once every two days, three times a week, for 4 weeks totally. The cervical spondylosis effect scale and the simplified McGill pain questionnaire were adopted to observe the improvements in the clinical symptoms, clinical examination, daily life movement, superficial muscular pain in the neck and the health economics cost in the patients of the two groups. The effect was evaluated in the two groups. The effective rate and the clinical curative rate in the combined therapy group were better than those in the control group [100. 0% (35/35) vs 85. 3% (29/34), 42. 9% (15/35) vs 17. 6% (6/34), both Pmassage therapy, the massage therapy combined with magnetic sticking therapy at auricular points achieves the better effect and lower cost in health economics.

    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. 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 fixed-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.

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

    Full Text Available In advanced nonsmall cell lung cancer (NSCLC patients, platinum-based combination chemotherapy is standard treatment in the first-line setting; however, the large majority of patients ultimately progress. For more than a decade, single-agent therapy with docetaxel, pemetrexed or erlotinib has been the standard of care after failure with platinum salts, showing some benefit over best supportive care. Nonetheless, prognosis remains poor and new second-line strategies are urgently needed. Combinations of cytotoxic agents, including rechallenge with platinum salts, do not offer clear benefit over single-agent therapy for the majority of patients. In patients without a known tumoural oncogenic driver mutation, regimens based on combinations of targeted agents have shown promising results; however, a clear role in therapeutic management is yet to be established. Some success has been reported in recent research combining a cytotoxic agent with targeted therapies. In this review, we summarise published data for the various strategies evaluated over the past decade in second-line treatment of NSCLC patients without a known driver mutation. We focus on combination treatments and consider future perspectives, including the need to identify predictive markers to support personalised therapeutic strategies.

    Adequate control of hyperlipidemia is of paramount importance for prevention of vascular events. Statins and fibrates are well established treatments for hyperlipidemia. Combination therapy with a statin and fibrate offers significant therapeutic advantage for the treatment of severe or refractory mixed hyperlipidemia. Although such a combination does increase the risk of myopathy, with an incidence of approximately 0.12%, this small risk of myopathy rarely outweighs the established morbidity and mortality benefits of achieving lipid goals. Nevertheless, a higher incidence of myopathy has been reported with statin monotherapy. Statin+fibrate therapy should be considered if monotherapy or adding other drugs (e.g. cholesterol absorption inhibitors, omega-3 fatty acids or nicotinic acid) did not achieve lipid targets or is impractical. The current article focuses on recent studies highlighting the beneficial effects of this combination. Copyright © 2012 Diabetes India. Published by Elsevier Ltd. All rights reserved.

    The combination of antidepressants and brief psychotherapies has been proven more efficacious in treating major depression and is particularly recommended in patients with concomitant personality disorders. We compare the effects of 2 combined therapies, fluoxetine and interpersonal therapy (IPT) or fluoxetine and cognitive therapy (CT), on major depression in patients with borderline personality disorder (BPD). Thirty-five consecutive outpatients with a diagnosis of BPD and a major depressive episode (not bipolar and not psychotic) were enrolled. They were randomly assigned to 1 of the 2 combined treatments and treated for 24 weeks. Assessment included a semistructured interview, Clinical Global Impression (CGI) scale, Hamilton Depression Rating Scale (HDRS), Hamilton Anxiety Rating Scale (HARS), Beck Depression Inventory-II (BDI-II), Social and Occupational Functioning Assessment Scale (SOFAS), Satisfaction Profile (SAT-P) for quality of life (QOL), and Inventory of Interpersonal Problems (IIP-64). Statistical analysis was performed using the univariate General Linear Model to calculate the effects of duration and type of treatment. No significant differences between treatments were found at CGI, HDRS, BDI-II, and SOFAS score. Combined treatment with CT had greater effects on HARS score and on psychological functioning factor of SAT-P. Combined treatment with IPT was more effective on social functioning factor of SAT-P and on domains domineering or controlling and intrusive or needy of IIP-64. Both combined therapies are efficacious in treating major depression in patients with BPD. Differences between CT and IPT concern specific features of subjective QOL and interpersonal problems. These findings lack reliable comparisons and need to be replicated.

    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.

    Graphene oxide (GO)-based theranostic nanohybrid is designed for tumor induced imaging and potential combinational tumor therapy. The anti-tumor drug, Doxorubicin (DOX) is chemically conjugated to the poly(ethylenimine)-co-poly(ethylene glycol) (PEI-PEG) grafted GO via a MMP2-cleavable PLGLAG peptide linkage. The therapeutic efficacy of DOX is chemically locked and its intrinsic fluorescence is quenched by GO under normal physiological condition. Once stimulated by the MMP2 enzyme over-expressed in tumor tissues, the resulting peptide cleavage permits the unloading of DOX for tumor therapy and concurrent fluorescence recovery of DOX for in situ tumor cell imaging. Attractively, this PEI-bearing nanohybrid can mediate efficient DNA transfection and shows great potential for combinational drug/gene therapy. This tumor induced imaging and potential combinational therapy will open a window for tumor treatment by offering a unique theranostic approach through merging the diagnostic capability and pathology-responsive therapeutic function. © 2013 WILEY-VCH Verlag GmbH & Co.

    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.

    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.

    Tumors cannot grow beyond a certain size (about 1-2 mm in diameter) through simple diffusion of oxygen and other essential nutrients into the tumor. Angiogenesis, the formation of blood vessels from pre-existing vessels, is a crucial and observed step, through which a tumor obtains its own blood supply. Thus, strategies that interfere with the development of this tumor vasculature, known as anti-angiogenic therapy, represent a novel approach to controlling tumor growth. Several pre-clinical studies have suggested that currently available angiogenesis inhibitors are unlikely to yield significant sustained improvements in tumor control on their own, but rather will need to be used in combination with conventional treatments to achieve maximal benefit. Optimal sequencing of anti-angiogenic treatment and radiotherapy or chemotherapy is essential to the success of these combined treatment strategies. Hence, a major challenge to mathematical modeling and computer simulations is to find appropriate dosages, schedules and sequencing of combination therapies to control or eliminate tumor growth. Here, we present a mathematical model that incorporates tumor cells and the vascular network, as well as their interplay. We can then include the effects of two different treatments, conventional cytotoxic therapy and anti-angiogenic therapy. The results are compared with available experimental and clinical data.

    Full Text Available Prognosis of patients with carcinoma of the exocrine pancreas is particularly poor. A combination of chemotherapy with immunotherapy could be an option for treatment of pancreatic cancer. The aim of this study was to perform an immunomonitoring of 17 patients with pancreatic cancer from the CapRI-2 study, and tumor-bearing mice treated with combination of chemo (radio therapies with interferon-2α. Low doses of interferon-2α led to a decrease in total leukocyte and an increase in monocyte counts. Furthermore, we observed a positive effect of interferon-2α therapy on the dendritic cells and NK (natural killer cell activation immediately after the first injection. In addition, we recorded an increased amount of interferon-γ and IL-10 in the serum following the interferon-2α therapy. These data clearly demonstrate that pancreatic carcinoma patients also show an immunomodulatory response to interferon-2α therapy. Analysis of immunosuppressive cells in the Panc02 orthotopic mouse model of pancreatic cancer revealed an accumulation of the myeloid-derived suppressor cells in spleens and tumors of the mice treated with interferon-2α and 5-fluorouracil. The direct effect of the drugs on myeloid-derived suppressor cells was also registered in vitro. These data expose the importance of immunosuppressive mechanisms induced by combined chemo-immunotherapy.

    Nasopharyngeal carcinoma (NPC) is very common in Southern China and Southeast Asian countries. To explore a novel and more effective approach to NPC therapy, a combined strategy of suicide genes and radiation was designed in this study. Five suicide gene expression cassettes, yeast cytosine deaminase (CD), yeast CD/uracil phosphoribosyl-transferase (UPRT), and yeast CDglyTK gene controlled by CMV, and Egr-1 and a synthetic CMV-enhanced Egr-1 promoter (CE) were constructed in an expression vector p11MS. The expression of suicide genes in NPC CNE-2 cells were detected by reverse transcription polymerase chain reaction (RT-PCR) and Western blot. The cytotoxicity of suicide gene therapy and radiation were analyzed by MTT assay. An animal study in which yeast CD/UPRT-expressing CNE-2 tumors in nude mice were treated with 5-fluorocytosine (5-FC) and radiation was also developed. Our results revealed that p11MSCEyCD/UPRT and p11MSCEyCDglyTK are superior over three other constructs in the killing of NPC cells in vitro. We combined suicide gene-expressing tumors, 5-FC treatment, and radiation in vivo and found that the tumors greatly regressed, some disappeared completely in 3 nude mice in the yCD/UPRT group, and a significant difference of tumor volumes was observed between this group and the other four groups (p<0.05). Our results indicated that suicide gene therapy and radiation have a synergic effect on NPC therapy, and the combined strategy of radiogene therapy is of great potential as a substitute for the traditional method, radiation alone, in NPC therapies.

    While conventional chemotherapy is effective at eliminating the bulk of leukemic cells, chemotherapy resistance in acute myeloid leukemia (AML) is a prevalent problem that hinders conventional therapies and contributes to disease relapse, and ultimately patient death. We have recently shown that allogeneic double negative T cells (DNTs) are able to target the majority of primary AML blasts in vitro and in patient-derived xenograft models. However, some primary AML blast samples are resistant to DNT cell therapy. Given the differences in the modes of action of DNTs and chemotherapy, we hypothesize that DNT therapy can be used in combination with conventional chemotherapy to further improve their anti-leukemic effects and to target chemotherapy-resistant disease. Drug titration assays and flow-based cytotoxicity assays using ex vivo expanded allogeneic DNTs were performed on multiple AML cell lines to identify therapy-resistance. Primary AML samples were also tested to validate our in vitro findings. Further, a xenograft model was employed to demonstrate the feasibility of combining conventional chemotherapy and adoptive DNT therapy to target therapy-resistant AML. Lastly, blocking assays with neutralizing antibodies were employed to determine the mechanism by which chemotherapy increases the susceptibility of AML to DNT-mediated cytotoxicity. Here, we demonstrate that KG1a, a stem-like AML cell line that is resistant to DNTs and chemotherapy, and chemotherapy-resistant primary AML samples both became more susceptible to DNT-mediated cytotoxicity in vitro following pre-treatment with daunorubicin. Moreover, chemotherapy treatment followed by adoptive DNT cell therapy significantly decreased bone marrow engraftment of KG1a in a xenograft model. Mechanistically, daunorubicin increased the expression of NKG2D and DNAM-1 ligands on KG1a; blocking of these pathways attenuated DNT-mediated cytotoxicity. Our results demonstrate the feasibility and benefit of using DNTs as

    Congestion is the most common reason for admissions and readmissions for heart failure (HF). The vast majority of hospitalized HF patients appear to respond readily to loop diuretics, but available data suggest that a significant proportion are being discharged with persistent evidence of congestion. Although novel therapies targeting congestion should continue to be developed, currently available agents may be utilized more optimally to facilitate complete decongestion. The combination of loop diuretics, natriuretic doses of mineralocorticoid receptor antagonists and vasopressin antagonists represents a regimen of currently available therapies that affects early and persistent decongestion, while limiting the associated risks of electrolyte disturbances, hemodynamic fluctuations, renal dysfunction and mortality.

    HER2-positive disease is an aggressive subtype of breast cancer that has been revolutionized by anti-HER2 directed therapies. Multiple drugs have been developed and are currently in clinical use, including trastuzumab, lapatinib, pertuzumab, T-DM1, and neratinib, alone or combined in 'dual HER2-blockade' regimens. Areas covered: A comprehensive literature review was performed regarding the current state and the future of combination regimens containing anti-HER2 agents, focusing on their efficacy, toxicity, and cost-effectiveness. Expert commentary: The combination of trastuzumab/pertuzumab is approved in all disease settings, while trastuzumab/neratinib is approved in the adjuvant setting and trastuzumab/lapatinib in metastatic disease. Meanwhile, as breast cancer biology and resistance mechanisms become clearer, combinations with drugs like PI3K/Akt/mTOR inhibitors, CDK4/6 inhibitors, anti-PD(L)1 antibodies, endocrine therapy, and new anti-HER2 agents (panHER and HER2 tyrosine kinase inhibitors, bispecific antibodies, anti-HER3 antibodies, and antibody-drug conjugates) are being extensively tested in clinical trials. More specific strategies for the 'triple-positive' (estrogen receptor-positive/HER2-positive) disease are also being explored. However, there is an urgent need for the development of predictive biomarkers for a better tailoring of anti-HER2 directed therapy. This is the only way to further improve clinical outcomes and quality of life and to decrease costs and toxicities of unnecessary treatments.

    Tumor drug resistance significantly limits the success of chemotherapy in the clinic. Tumor cells utilize multiple mechanisms to prevent the accumulation of anticancer drugs at their intracellular site of action. In this study, we investigated the anticancer efficacy of doxorubicin in combination with photodynamic therapy using methylene blue in a drug-resistant mouse tumor model. Surfactant-polymer hybrid nanoparticles formulated using an anionic surfactant, Aerosol-OT (AOT), and a naturally occurring polysaccharide polymer, sodium alginate, were used for synchronized delivery of the two drugs. Balb/c mice bearing syngeneic JC tumors (mammary adenocarcinoma) were used as a drug-resistant tumor model. Nanoparticle-mediated combination therapy significantly inhibited tumor growth and improved animal survival. Nanoparticle-mediated combination treatment resulted in enhanced tumor accumulation of both doxorubicin and methylene blue, significant inhibition of tumor cell proliferation, and increased induction of apoptosis. These data suggest that nanoparticle-mediated combination chemotherapy and photodynamic therapy using doxorubicin and methylene blue has significant therapeutic potential against drug-resistant tumors.

    Full Text Available 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.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.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 available.

  3. Analysis of combination drug therapy to develop regimens with shortened duration of treatment for tuberculosis.

    George L Drusano

    Full Text Available 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.

    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.

    Combination therapy with S-1, superselective intra-arterial infusion of carboplatin (CBDCA) and radiation therapy has been used to treat patients with oral cancer since 2005. In this study, the histopathological effects and toxicities following concurrent chemoradiotherapy were examined. The subjects consisted of 15 patients (10 men and 5 women) who were treated with S-1 (60-80 mg/day, 4 weeks), superselective intra-arterial infusion of CBDCA (300 mg/body) and radiation therapy (total dose 30-36 Gy) in our department from 2005 to 2009. Nine patients, showed T2 disease, 3 showed T3 disease, and another 3 showed T4 diseases. The primary cancer sites were the tongue (6 cases), buccal mucosa (4 cases), mandible gingival (3 cases), maxillary gingival (1 case), and the floor of the mouth (1 case). The histopathological effects were evaluated according to Oboshi-Shimosato classification. Grade IV was shown in 10 cases (66.7%), grade III in 1 case (6.7%), II bin 3 cases (20.0%), and II a in 1 case (6.7%). All patients completed the treatment. The pathological response of the resected tumor was grade IIb or higher in 14 cases (93.3%). While good histological effects were noted, there was one patient for whom viable tumor cells remained in the central part of the tumor. The present study indicates that further investigation is needed to determine the best dosing and dosing schedule. (author)

    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

    Full text of publication follows. Aim: successful treatment of patients with somatostatin receptor over-expressing neuroendocrine tumours (NET) with Lutetium-177-labelled octreotate, (PRRT) or temozolomide (TMZ) as single treatments has been described. Their combination might result in additive response, so we studied tumour characteristics and therapeutic responses after different administration schemes in mice to obtain the optimal strategy to combine PRRT and TMZ. Materials and methods: Initially we performed imaging studies of nu/nu mice, (n=5-8) bearing somatostatin receptor-expressing human H69 small cell lung carcinoma xenografts, after single administration of 177 Lu-octreotate (30 MBq/μg) or TMZ therapy (50 mg/kg/day (d) 5 x/ week for 2 weeks). Weekly tumour perfusion was measured by DCE-MRI and tumour 111 In-uptake 24 hours after administration of 30 MBq 111 In-octreotide was quantified using SPECT/CT. Based on the imaging results, seven groups were included in a combination therapy study in H69 tumour-bearing mice (n=8-9): 1: control (saline), 2: TMZ, 3: PRRT, 4: PRRT + TMZ both d1, 5: PRRT d1, TMZ from d15, 6: TMZ from d1, PRRT d15, 7: PRRT d1 and d15. Study endpoint was tumour volume >1800-2000 mm 3 . Results: single treatment with 177 Lu-octreotate or TMZ therapy resulted in reduction of tumour size, which led to changes in MRI characteristics such as intrinsic T2, T2* and perfusion values. Moreover, TMZ treatment not only showed tumour size reduction 9 days after start of treatment and an increase in MRI perfusion parameters but uptake of 111 In-octreotide peaked at day 15 followed by a decrease afterwards. In the combination therapy study no complete cure was found in control, single TMZ and single and double PRRT groups, while in the TMZ/PRRT combination groups resp. 44%, 38% and 55% of mice (groups 4, 5 and 6) showed cure without recurrence of tumour growth during follow-up. This was also reflected in an extended median survival time (MST), resp

    Full Text Available To construct and validate a prediction model for individual combined benefit and harm outcomes (stroke with no major bleeding, major bleeding with no stroke, neither event, or both in patients with atrial fibrillation (AF with and without warfarin therapy.Using the Kaiser Permanente Colorado databases, we included patients newly diagnosed with AF between January 1, 2005 and December 31, 2012 for model construction and validation. The primary outcome was a prediction model of composite of stroke or major bleeding using polytomous logistic regression (PLR modelling. The secondary outcome was a prediction model of all-cause mortality using the Cox regression modelling.We included 9074 patients with 4537 and 4537 warfarin users and non-users, respectively. In the derivation cohort (n = 4632, there were 136 strokes (2.94%, 280 major bleedings (6.04% and 1194 deaths (25.78% occurred. In the prediction models, warfarin use was not significantly associated with risk of stroke, but increased the risk of major bleeding and decreased the risk of death. Both the PLR and Cox models were robust, internally and externally validated, and with acceptable model performances.In this study, we introduce a new methodology for predicting individual combined benefit and harm outcomes associated with warfarin therapy for patients with AF. Should this approach be validated in other patient populations, it has potential advantages over existing risk stratification approaches as a patient-physician aid for shared decision-making.

  10. 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.

    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. We applied a random-effects meta-analysis, using the odds ratio (OR) to describe dichotomous outcomes, mean difference (MD) to describe continuous outcomes when the same measures were used, and standard mean difference (SMD) when

Effect of the two variants of combination therapy on LVH was used to estimate treatment effectiveness and to build the model. Patients were distributed according to the left ventricular mass (LVM at baseline and after 24 weeks of therapy. Significant decrease in LVM was observed in V/A group: from 225.1±71.7 to 186.3±44.5 g (p<0.05. There was no LVM dynamics in L/A group. The model took into account economic and frequency factors for 10 years forecast. V/A therapy is able to prevent 94 deaths, 22 strokes, and 64 myocardial infarction per 1000 patients. Absence of need in treatment of these prevented events can save about 5.5 million RUR for every 1000 patients. It would reduce the total costs per patient during 10 years. V/A therapy is able to save maximal number of quality adjusted life years (QALY due to LVM regression (5.016 years. L/A combination is the most economical variant of pharmacotherapy due to low cost of treatment (16.491.25 RUR per 1 QALY.

    During the period 1982-1988, 34 patients with advanced oral or oropharyngeal carcinoma were treated with radical radiation therapy combined with intraarterial chemotherapy. Five patients were clinically staged as Stage II,15 as Stage III, and 14 as Stage IV. For intraarterial chemotherapy, ACNU (25mg/body) or CDDP (20 mg/m 2 ) plus MMC (6 mg/m 2 ) was used. Overall, the complete response rate was 56%: it was independent of the site of carcinoma, clinical stage, and the kind of drugs. The two-year cumulative survival rate was 80% for Stage II, 56% for Stage III, and 61% for Stage IV. Side effects were not so severe as to continue with the withdrawal of chemotherapy. In view of the efficacy and safety, combined radiation therapy and intraarterial chemotherapy should be performed in the treatment of oral or oropharyngeal carcinoma. (N.K.)

    We report "smart" nickel oxide nanoparticles (NOPs) as multimodal cancer therapy agent. Water-dispersible and light-sensitive NiO core was synthesized with folic acid (FA) connected bovine serum albumin (BSA) shell on entrapped doxorubicin (DOX). The entrapped drug from NOP-DOX@BSA-FA was released in a sustained way (64 hours, pH=5.5, dark conditions) while a robust release was found under red light exposure (in 1/2 hour under λmax=655 nm, 50 mW/cm(2), at pH=5.5). The cell viability, thiobarbituric acid reactive substances and diphenylisobenzofuran assays conducted under light and dark conditions revealed a high photodynamic therapy potential of our construct. Furthermore, we found that the combined effect of DOX and NOPs from NOP-DOX@BSA-FA resulted in cell death approximately eightfold high compared to free DOX. We propose that NOP-DOX@BSA-FA is a potential photodynamic therapy agent and a collective drug delivery system for the systemic administration of cancer chemotherapeutics resulting in combination therapy.

    Rat glioma model was used to evaluate the effect of hyperthermia with and without radiation therapy. The animal model was induced by left frontal burr hole opening and inoculation of a small piece of G-XII glioma tissue to 6- to 8-week-old rats. The therapeutical experiments were given 10 - 14 days after inoculation of the tumor. Interstitial heating at 44 and 45 deg C at the surface of the inserting probe using 2450 MHz microwave was delivered for 30 minutes. Deep X-ray whole head irradiation of 800 R using Stabilipan 2 (Siemens) was given just after the hyperthermia therapy. The survival of treated animals of hyperthermia, radiation, and combination of hyperthermia and radiation was significantly superior to that of non-treated control group. There was no significant difference of survival among the treated groups, though median survival was longest in the group of combination therapy of hyperthermia and radiation. Large tumors developed at the time of death in all the control and the treated animals. Histological examination showed some tendencies of macrophage infiltration in tumor tissue of hyperthermia therapy. (author)

    Treatment of prosthetic joint infections often involves a two-stage exchange, with implant removal and antibiotic spacer placement followed by systemic antibiotic therapy and delayed reimplantation. However, if antibiotic therapy can be improved, one-stage exchange or implant retention may be more feasible, thereby decreasing morbidity and preserving function. In this study, a mouse model of prosthetic joint infection was used in which Staphylococcus aureus was inoculated into a knee joint containing a surgically placed metallic implant extending from the femur. This model was used to evaluate whether combination therapy of vancomycin plus rifampin has increased efficacy compared with vancomycin alone against these infections. On postoperative day 7, vancomycin with or without rifampin was administered for 6 weeks with implant retention. In vivo bioluminescence imaging, ex vivo CFU enumeration, X-ray imaging, and histologic analysis were carried out. We found that there was a marked therapeutic benefit when vancomycin was combined with rifampin compared with vancomycin alone. Taken together, our results suggest that the mouse model used could serve as a valuable in vivo preclinical model system to evaluate and compare efficacies of antibiotics and combinatory therapy for prosthetic joint infections before more extensive studies are carried out in human subjects.

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

    Enterococci are common causes of infective endocarditis (IE) in both health care and community-based setting. Enterococcal IE requires bactericidal therapy for an optimal outcome. For decades, cell-wall-active antimicrobial agents (penicillins or vancomycin) in combination with aminoglycosides were the cornerstone of the treatment; however, the emergence of antibiotic resistance has significantly reduced the efficacy of these regimens. Data for this review were identified by searches of MEDLINE and references from relevant articles on antibiotic combination regimens for the treatment of enterococcal IE. Abstracts presented in scientific conferences were not searched for. New effective and safe combination treatments, including double-β-lactam and daptomycin/β-lactam combination, are proving useful for the management of IE due to enterococci.

    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.

    Combination therapy for the treatment of cancer is becoming more popular because it generates synergistic anticancer effects, reduces individual drug-related toxicity and suppresses multi-drug resistance through different mechanisms of action. In recent years, nanotechnology-based combination drug delivery to tumor tissues has emerged as an effective strategy by overcoming many biological, biophysical and biomedical barriers that the body stages against successful delivery of anticancer drugs. The sustained, controlled and targeted delivery of chemotherapeutic drugs in a combination approach enhanced therapeutic anticancer effects with reduced drug-associated side effects. In this article, we have reviewed the scope of various nanotechnology-based combination drug delivery approaches and also summarized the current perspective and challenges facing the successful treatment of cancer.

    Full Text Available Current antiviral treatment strategy for chronic hepatitis B (CHB includes pegylated interferon (PEG-IFN and nucleos(tide analogues (NAs. Whether combination therapy with PEG-IFN and NAs improve therapeutic efficacy has become the key question regarding the antiviral therapy for CHB. This article reviews the recent progress in combination therapy for the management of CHB. The results indicate that the efficacy of simultaneous combination of PEG-IFN and NAs is not superior to that of PEG-IFN monotherapy in terms of HBeAg seroconversion and response after drug withdrawal. Sequential combination or switching therapy in PEG-IFN- or NAs-treated patients, as well as combination with immune cell therapy, is a promising treatment strategy.

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

Combined therapy with PD and hemodialysis (HD) is the treatment of choice for patients who cannot control body fluid status and/or cannot obtain adequate solute removal by PD alone. The aim of this study was to evaluate the clinical efficacy of this combined therapy. In this retrospective study, 53 patients on PD and diagnosed with underdialysis and/or overhydration with declining RRF were recruited. Parameters of volume control, uremic solute removal, anemia, and predictors for encapsulating peritoneal sclerosis (EPS) were compared before and 1 year after combined therapy. The patients' hydration status improved significantly with reductions in atrial natriuretic peptide and blood pressure. Serum creatinine and beta2 microglobulin also decreased significantly. The hemoglobin level increased remarkably from 8.2 ± 1.6 to 10.7 ± 1.2 g/dl (p < 0.01) and the reticulocyte count also increased significantly, even though at the same time the dose of recombinant human erythropoietin decreased significantly. The dialysate to plasma creatinine ratio obtained from the fast peritoneal equilibration test (PET) decreased significantly from 0.65 ± 0.11 to 0.59 ± 0.13, and the level of interleukin 6 in PET drainage also significantly decreased. Furthermore, serum C-reactive protein and fibrinogen decreased significantly. Combined therapy with PD and HD is an effective way to control fluid status and to correct inadequate solute removal, leading to improvement in inflammation, peritoneal function and anemia.

    The morbidity and mortality benefits of lowering blood pressure (BP) in hypertensive patients are well established, with most individuals requiring multiple agents to achieve BP control. Considering the important role of the renin-angiotensin-aldosterone system (RAAS) in the pathophysiology of hypertension, a key component of combination therapy should include a RAAS inhibitor. Angiotensin receptor blockers (ARBs) lower BP, reduce cardiovascular risk, provide organ protection, and are among t...

    To compare the effectiveness of music, oral sucrose, and combination therapy for pain relief in neonates undergoing a heel prick procedure. This randomized, controlled, blinded crossover clinical trial included stable neonates >32 weeks of postmenstrual age. Each neonate crossed over to all 3 interventions in random order during consecutive heel pricks. A video camera on mute mode recorded facial expressions, starting 2 minutes before until 7 minutes after the heel prick. The videos were later analyzed using the Premature Infant Pain Profile-Revised (PIPP-R) scale once per minute by 2 independent assessors, blinded to the intervention. The PIPP-R scores were compared between treatment groups using Friedman test. For the 35 participants, the postmenstrual age was 35 weeks (SD, 2.3) with an average weight of 2210 g (SD, 710). The overall median PIPP-R scores following heel prick over 6 minutes were 4 (IQR 0-6), 3 (IQR 0-6), and 1 (IQR 0-3) for the music, sucrose, and combination therapy interventions, respectively. The PIPP-R scores were significantly lower at all time points after combination therapy compared with the groups given music or sucrose alone. There was no difference in PIPP-R scores between the music and sucrose groups. In relatively stable and mature neonates, the combination of music therapy with sucrose provided better pain relief during heel prick than when sucrose or music was used alone. Recorded music in isolation had a similar effect to the current gold standard of oral sucrose. www.anzctr.org.au ACTRN12615000271505. Copyright © 2017 Elsevier Inc. All rights reserved.

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 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.

    1979-01-01

    Seventeen consecutive patients with localized, high grade soft tissue sarcomas had resection of their primary tumor, radiation therapy and chemotherapy. The soft tissue sarcoma was primary in 14 patients and regionally recurrent in 3 patients. Chemotherapy consisted of cyclophosphamide 500 mg/M 2 day 1, Adriamycin (ADR) 60 mg/M 2 day 2, and DTIC 400 mg/M 2 days 1 and 2, given every 21 days to a maximum ADR dose of 450 mg/M 2 . Cyclophosphamide and DTIC were then given to a total duration of 1 year. Radiation therapy consisted of 4000 to 5000 rad by megavoltage photons in 5 weeks, and in selected cases, an additional 1500 to 2000 rad by electron beam boost in the tumor bed delivered over 2 additional weeks. Following surgery, 12 patients were treated sequentially with an interval of chemotherapy, radiation therapy and then the completion of chemotherapy. The added morbidity of this sequential approach is minimal: one patient of 12 had delayed primary healing of her wound, 1 of 10 patients required a break in radiation therapy because of skin erythema. Four patients were treated with intensive pre-chemotherapy radiation therapy because of inadequate surgical margins. The median time on study was 18 months from onset of treatment (range, 8 to 41 months). Although there have been no local, regional or distant recurrences, the follow-up time is inadequate to assess the therapeutic benefit of this combined modality treatment

    2013-06-01

    This study examined (a) duration of generalized anxiety disorder (GAD) as a moderator of cognitive behavioral therapy (CBT) versus its components (cognitive therapy and self-control desensitization) and (b) increases in dynamic flexibility of anxious symptoms during the course of psychotherapy as a mediator of this moderation. Degree of dynamic flexibility in daily symptoms was quantified as the inverse of spectral power due to daily to intradaily oscillations in four-times-daily diary data (Fisher, Newman, & Molenaar, 2011). This was a secondary analysis of the data of Borkovec, Newman, Pincus, and Lytle (2002). Seventy-six participants with a principle diagnosis of GAD were assigned randomly to combined CBT (n = 24), cognitive therapy (n = 25), or self-control desensitization (n = 27). Duration of GAD moderated outcome such that those with longer duration showed greater reliable change from component treatments than they showed from CBT, whereas those with shorter duration fared better in response to CBT. Decreasing predictability in daily and intradaily oscillations of anxiety symptoms during therapy reflected less rigidity and more flexible responding. Increases in flexibility over the course of therapy fully mediated the moderating effect of GAD duration on condition, indicating a mediated moderation process. Individuals with longer duration of GAD may respond better to more focused treatments, whereas those with shorter duration of GAD may respond better to a treatment that offers more coping strategies. Importantly, the mechanism by which this moderation occurs appears to be the establishment of flexible responding during treatment.

    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.

    Full Text Available Abstract Background Photodynamic therapy (PDT is a promising cancer treatment modality that involves the interaction of the photosensitizer, molecular oxygen and light of specific wavelength to destroy tumor cells. Treatment induced hypoxia is one of the main side effects of PDT and efforts are underway to optimize PDT protocols for improved efficacy. The aim of this study was to investigate the anti-tumor effects of PDT plus Erbitux, an angiogenesis inhibitor that targets epidermal growth factor receptor (EGFR, on human bladder cancer model. Tumor-bearing nude mice were assigned to four groups that included control, PDT, Erbitux and PDT plus Erbitux and tumor volume was charted over 90-day period. Results Our results demonstrate that combination of Erbitux with PDT strongly inhibits tumor growth in the bladder tumor xenograft model when compared to the other groups. Downregulation of EGFR was detected using immunohistochemistry, immunofluorescence and western blotting. Increased apoptosis was associated with tumor inhibition in the combination therapy group. In addition, we identified the dephosphorylation of ErbB4 at tyrosine 1284 site to play a major role in tumor inhibition. Also, at the RNA level downregulation of EGFR target genes cyclin D1 and c-myc was observed in tumors treated with PDT plus Erbitux. Conclusion The combination therapy of PDT and Erbitux effectively inhibits tumor growth and is a promising therapeutic approach in the treatment of bladder tumors.

    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

    The purpose of this study was to evaluate vocal tract function and the voice quality in singers with muscle tension dysphonia (MTD) after undergoing combined functional voice therapy of the singing voice. This is a prospective, randomized study. Forty singers (29 females and 11 males, mean age: 24.6 ± 8.8 years) with MTD were enrolled in the study. The study group consisted of 20 singers who underwent combined functional voice therapy (10-15 individual sessions, 30-40 minutes each). Singers who did not opt for vocal rehabilitation consisted of the control group. Effects of rehabilitation were assessed with videolaryngostroboscopy, palpation of the vocal tract structures, flexible fiberoptic evaluation of the pharynx and the larynx, perceptual speaking and singing voice assessment, acoustic analysis, maximal phonation time, and the Voice Handicap Index. After combined functional voice therapy in the study group, great improvement was noticed in palpation of the vocal tract structures (P singing range obtained from acoustic analysis of glissando (P singing. Development of palpation and perceptual singing voice examination protocols enables one to compare results before and after rehabilitation in clinics. Copyright © 2017 The Voice Foundation.

    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.

    As the use of hormone replacement therapy for the menopausal women increases, some caution is advised, since there is an increased risk of breast cancer. Accordingly, the importance of regular mammography has been addressed. This cross-setional study analyzed the effects of different hormone therapies on mammographic density. Sixty-seven postemenopausal women who had completed one year of hormone therapy and had undergone follow-up mammography, were divided into two groups : Group I : continuous conjugated equine estrogen, 0.625mg, plus continuous medroxyprogesterone acetate, 2.5mg (n=48), Group II : continuous conjugated equine estrogen 0.625mg (n=19). The mammograms were read by two radiologists. With regard to the radiologists involved, interobserver reliabillity (kappa) was 0.70 and intraobserver reliability (kappa) was 0.51 and 0.67. Before hormone therapy, factors related to decreased mammographic density were age and number of full term pregnancies (p<0.05). After one year of hormone therapy, body fat showed a significant increase (p<0.05), but in spite of this, increased mammographic density induced by hormone therapy remained significantly high (p<0.05). Compared with Group II, Group I showed a significant increase in mammographic density (p<0.05). In Group I, mammographic density increased from P2 to DY pattern in two cases, but there was no such change in Group II. The increase of mammographic density seen in Group II was much more significant statistically than that seen in Group I. The mammograms of women who have undergone continuous combined hormone therapy should therefore be interpreted very cautiously.

    L-thyroxine replacement therapy is the treatment of choice for hypothyroidism. Recently, several studies suggested to complete it with l-triiodothyronine in acquired hypothyroidism. To study the role of combined l-thyroxine and l-triiodothyronine therapy in special cases with congenital hypothyroidism. Data of 16 patients (age: 11.9 ± 6.3 years; mean ± SD) are presented who had high serum free thyroxine values or even above the upper limit of reference range (21.16 ± 2.5 pmol/l) together with nonsuppressed TSH levels (15.7 ± 5.7 mIU/l), and therefore received l-triiodothyronine in completion (0.18 ± 0.09 μg/kg) once a day. The combined replacement therapy resulted in a rapid improvement of the hormone parameters (TSH: 4.2 ± 3.15 mIU/l; free thyroxine: 16.55 ± 2.4 and free triiodothyronine: 7.4 ± 1.8 pmol/l). The efficiency of this combined therapy proved to be more evident (TSH: 4.33 ± 3.2 mIU/l; free thyroxine: 16.85 ± 3.1 and free triiodothyronine: 6.4 ± 0.85 pmol/l) in 10 patients treated for a longer period of time (duration of treatment: 2.9 ± 2.0 years). The dose of thyroxine substitution decreased from 2.6 ± 0.9 to 2.18 ± 0.6 μg/kg/day), the ratio of these hormones was between 5:1 and 19:1 and the quotient of free fractions was normalized (3.8 ± 0.4→2.6 ± 0.3) during the replacement therapy. According to the observation of the authors a serious disturbance of feed-back mechanism may develop in some (>5%) children with congenital hypothyroidism (increased TSH release despite elevated free thyroxine level) after normal function of the feed-back system for years. Hormone parameters of these patients improve, then become normal on combined therapy supporting the rationale for this treatment method.

    Purpose: To determine the rate of treatment deviations during combined modality therapy for rectal cancer in elderly patients aged 75 years and older. Methods and Materials: We reviewed the records of consecutively treated patients with rectal cancer aged 75 years and older treated with combined modality therapy at Massachusetts General Hospital and Brigham and Women’s Hospital from 2002 to 2007. The primary endpoint was the rate of treatment deviation, defined as a treatment break, dose reduction, early discontinuation of therapy, or hospitalization during combined modality therapy. Patient comorbidity was rated using the validated Adult Comorbidity Evaluation 27 Test (ACE-27) comorbidity index. Fisher’s exact test and the Mantel–Haenszel trend test were used to identify predictors of treatment tolerability. Results: Thirty-six eligible patients had a median age of 79.0 years (range, 75–87 years); 53% (19/36) had no or mild comorbidity and 47% (17/36) had moderate or severe comorbidity. In all, 58% of patients (21/36) were treated with preoperative chemoradiotherapy (CRT) and 33% (12/36) with postoperative CRT. Although 92% patients (33/36) completed the planned radiotherapy (RT) dose, 25% (9/36) required an RT-treatment break, 11% (4/36) were hospitalized, and 33% (12/36) had a dose reduction, break, or discontinuation of concurrent chemotherapy. In all, 39% of patients (14/36) completed ≥4 months of adjuvant chemotherapy, and 17% (6/36) completed therapy without a treatment deviation. More patients with no to mild comorbidity completed treatment than did patients with moderate to severe comorbidity (21% vs. 12%, p = 0.66). The rate of deviation did not differ between patients who had preoperative or postoperative CRT (19% vs. 17%, p = 1.0). Conclusions: The majority of elderly patients with rectal cancer in this series required early termination of treatment, treatment interruptions, or dose reductions. These data suggest that further intensification

    The goal of the study was to assess the efficacy of combined extracellular matrix metalloprotease inducer (EMMPRIN)- and death receptor 5 (DR5)-targeted therapy for pancreatic adenocarcinoma in orthotopic mouse models with multimodal imaging. Cytotoxicity of anti-EMMPRIN antibody and anti-DR5 antibody (TRA-8) in MIA PaCa-2 and PANC-1 cell lines was measured by ATPlite assay in vitro. The distributions of Cy5.5-labeled TRA-8 and Cy3-labeled anti-EMMPRIN antibody in the 2 cell lines were analyzed by fluorescence imaging in vitro. Groups 1 to 12 of severe combined immunodeficient mice bearing orthotopic MIA PaCa-2 (groups 1-8) or PANC-1 (groups 9-12) tumors were used for in vivo studies. Dynamic contrast-enhanced-MRI was applied in group 1 (untreated) or group 2 (anti-EMMPRIN antibody). The tumor uptake of Tc-99m-labeled TRA-8 was measured in group 3 (untreated) and group 4 (anti-EMMPRIN antibody). Positron emission tomography/computed tomography imaging with (18)F-FDG was applied in groups 5 to 12. Groups 5 to 8 (or groups 9 to 12) were untreated or treated with anti-EMMPRIN antibody, TRA-8, and combination, respectively. TRA-8 showed high killing efficacy for both MIA PaCa-2 and PANC-1 cells in vitro, but additional anti-EMMPRIN treatment did not improve the cytotoxicity. Cy5.5-TRA-8 formed cellular caps in both the cell lines, whereas the maximum signal intensity was correlated with TRA-8 cytotoxicity. Anti-EMMPRIN therapy significantly enhanced the tumor delivery of the MR contrast agent, but not Tc-99m-TRA-8. Tumor growth was significantly suppressed by the combination therapy, and the additive effect of the combination was shown in both MIA PaCa-2 and PANC-1 tumor models.

Water-dispersible and light-sensitive NiO core was synthesized with folic acid (FA connected bovine serum albumin (BSA shell on entrapped doxorubicin (DOX. The entrapped drug from NOP-DOX@BSA-FA was released in a sustained way (64 hours, pH=5.5, dark conditions while a robust release was found under red light exposure (in 1/2 hour under λmax=655 nm, 50 mW/cm2, at pH=5.5. The cell viability, thiobarbituric acid reactive substances and diphenylisobenzofuran assays conducted under light and dark conditions revealed a high photodynamic therapy potential of our construct. Furthermore, we found that the combined effect of DOX and NOPs from NOP-DOX@BSA-FA resulted in cell death approximately eightfold high compared to free DOX. We propose that NOP-DOX@BSA-FA is a potential photodynamic therapy agent and a collective drug delivery system for the systemic administration of cancer chemotherapeutics resulting in combination therapy.

    The normal tissue effects of radiation-adriamycin combination therapy were studied in the renoprival weanling mouse in an attempt to determine whether compensatory renal growth inhibition from radiation and chemotherapy could be associated with structural or functional abnormalities. Weanling BLc/sub Fl/ mice underwent unilateral nephrectomy, then single fraction renal irradiation, LD 1/21 doses of adriamycin in 5 daily doses, or combination therapy with radiation and adriamycin. Animals were sacrificed at 3, 12, and 24 weeks. Compensatory renal growth, body growth, serum blood urea nitrogen (BUN), and renal morphology by light microscopy were evaluated. Significant compensatory renal growth inhibition from radiation-adriamycin therapy exceeded that produced by adriamycin alone and radiation alone, at all time periods (p < 0.005). Body growth inhibition from radiation-adriamycin therapy or adriamycin alone significantly exceeded that produced by radiation alone (p < 0.005). Kidney and body growth inhibition from radiation-adriamycin therapy was proportionately severe. Kidney growth inhibition proportionately exceeded body growth inhibition with radiation alone; body growth inhibition proportionately exceeded kidney growth inhibition with adriamycin alone. Comparable azotemia developed by 24 weeks in both the radiation alone (p < .005) and radiation-adriamycin animals (p < 0.005), but not in the adriamycin only animals. Morphologic alterations consisting of increased glomerular density, tubular atrophy, and stromal fibrosis occurred with greater severity in the radiation-adriamycin animals than in the radiation only animals by 24 weeks; no alterations were seen in the adriamycin only animals. Using histologic criteria 750 rad plus adriamycin produced comparable injury as seen with 1000 rad alone, thus adriamycin produced an apparent dose-modifying factor of 1.33

    Background Drug resistance in Plasmodium falciparum poses a major threat to malaria control. Combination antimalarial therapy including artemisinins has been advocated recently to improve efficacy and limit the spread of resistance, but artemisinins are expensive and relatively untested in highly endemic areas. We compared artemisinin-based and other combination therapies in four districts in Uganda with varying transmission intensity. Methods and Findings We enrolled 2,160 patients aged 6 mo or greater with uncomplicated falciparum malaria. Patients were randomized to receive chloroquine (CQ) + sulfadoxine-pyrimethamine (SP); amodiaquine (AQ) + SP; or AQ + artesunate (AS). Primary endpoints were the 28-d risks of parasitological failure either unadjusted or adjusted by genotyping to distinguish recrudescence from new infections. A total of 2,081 patients completed follow-up, of which 1,749 (84%) were under the age of 5 y. The risk of recrudescence after treatment with CQ + SP was high, ranging from 22% to 46% at the four sites. This risk was significantly lower (p AQ + SP or AQ + AS (7%–18% and 4%–12%, respectively). Compared to AQ + SP, AQ + AS was associated with a lower risk of recrudescence but a higher risk of new infection. The overall risk of repeat therapy due to any recurrent infection (recrudescence or new infection) was similar at two sites and significantly higher for AQ + AS at the two highest transmission sites (risk differences = 15% and 16%, pAQ + AS was the most efficacious regimen for preventing recrudescence, but this benefit was outweighed by an increased risk of new infection. Considering all recurrent infections, the efficacy of AQ + SP was at least as efficacious at all sites and superior to AQ + AS at the highest transmission sites. The high endemicity of malaria in Africa may impact on the efficacy of artemisinin-based combination therapy. The registration number for this trial is ISRCTN67520427 (http

    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.

    Full Text Available Treatment outcomes in patients with age-related vascular degeneration due to formation of subretinal neovascular membrane (SNM of two groups: photodynamic therapy (PDT with Photosens alone (18 patients and in combination with anti-VEGF therapy with Lucentis (20 patients. For both groups Photosens was administrated i.v. in single dose of 0.05 mg/kg. The irradiation was performed on the 3rd day (the wave length 675 nm, light dose 120 J/cm2, total light dose did not exceed 500 J/cm2. The number of sessions accounted for 3 to 5 per week according to clinical manifestation of SNM. Patients with multimodality treatment had intravitreal administration of Lucensis in dose 0.05 ml (0.5 mg. The study showed that combination of PDT and anti-VEGF therapy improved vision better and with more stable effect then PDT alone. Thus vision improvement and decrease of SNM activity occurred in 50% of patients with PDT alone and in 60% of patients with multimodality treatment. For 2-year follow-up in the group of PDT alone the vision gradient gradually decreased compared with baseline vision (from 0.11 to 0.06, in the group of multimodality treatment gradual increase of vision gradient was noticed (from 0.03 to 0.155. The superior efficiency of PDT combined with anti-VEGF therapy compared with PDT alone in patients with age-related vascular degeneration was confirmed by study of vision, fundus angiography and average thickness of retina in foveola in both groups.

    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. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To improve the effectiveness of treatment for patients with stage C prostate cancer, therapy in combination with hormonal, radiation and chemotherapy was given for the initial period, and there after, hormonal therapy was continuously administered to 18 patients with chemotherapy and three patients without it. At the Social Health Insurance Medical Center, between May 1988 and August 1991, 21 patients were diagnosed to have stage C histologically confirmed adenocarcinoma of the prostate. The average age of the patients was 69.0 years. The tumor was well, moderate and poorly differentiated in 5, 6 and 10 patients, respectively. As hormonal therapy, orchiectomy was performed on 19 of the 21 patients. Furthermore, 11 patients were administered estramustine phosphate, 9 chlormadinone acetate, and one diethylstilbesterol diphosphate. As, radiation therapy, all patients were treated with AP-PA parallel opposing technique to small pelvis with a 12 cm x 12 cm treatment field (44-45 Gy) combined with conformation radiotherapy to prostate (20-26 Gy). Chemotherapy was performed using either one or a combination of the following; cis-diamminedichloroplatinum, adriamycin, cyclophosphamide, 5-fluorouracil, methotrexate and etoposide. The observation period was 54.5 months on the average. Recurrence was observed in 3 patients, for all of which the sites were at bone. The 5-year non-recurrence rate was 90.4% by Kaplan-Meier's method. There were 4 deaths, three were due to prostate cancer and one to gastric cancer. The 5-year cumulative survival rate by Kaplan-Meier's method was 90.5%. In conclusion, this treatment was effective for stage C cases of prostate cancer. (author)

    Edaravone, a potent antioxidant, may improve thrombolytic therapy because it benefits ischemic stroke patients on its own and mitigates adverse effects of tissue plasminogen activator (tPA) in preclinical models. However, whether the combined tPA-edaravone therapy is more effective in reducing infarct size than singular treatment is uncertain. Here we investigated this issue using a transient hypoxia-ischemia (tHI)-induced thrombotic stroke model, in which adult C57BL/6 mice were subjected to reversible ligation of the unilateral common carotid artery plus inhalation of 7.5% oxygen for 30 min. While unilateral occlusion of the common carotid artery suppressed cerebral blood flow transiently, the addition of hypoxia triggered reperfusion deficits, endogenous thrombosis, and attenuated tPA activity, leading up to infarction. We compared the outcomes of vehicle-controls, edaravone treatment, tPA treatment at 0.5, 1, or 4 h post-tHI, and combined tPA-edaravone therapies with mortality rate and infarct size as the primary end-points. The best treatment was further compared with vehicle-controls in behavioral, biochemical, and diffusion tensor imaging (DTI) analyses. We found that application of tPA at 0.5 or 1 h--but not at 4 h post-tHI--significantly decreased infarct size and showed synergistic (pedaravone treatment, respectively. The acute tPA-edaravone treatment conferred >50% reduction of mortality, ∼ 80% decline in infarct size, and strong white-matter protection. It also improved vascular reperfusion and decreased oxidative stress, inflammatory cytokines, and matrix metalloproteinase activities. In conclusion, edaravone synergizes with acute tPA treatment in experimental thrombotic stroke, suggesting that clinical application of the combined tPA-edaravone therapy merits investigation.

    Nowadays, there are several noninvasive technologies being used for improving of body contouring. The objectives of this pilot study were to verify the effectiveness of the Heccus ® device, emphasizing the synergism between nonfocused ultrasound plus Aussie current in the improvement of body contour, and to determine if the association of this therapy with whole-body vibration exercises can have additional positive effects in the results of the treatments. Twenty healthy women aged 20-40 years participated in the study. Ten patients received Combined Therapy treatment (G1) and the other 10 participants received Combined Therapy with additional vibratory platform treatment (G2). Anthropometric and standardized photography analysis, ultrasonography, cutometry and self-adminestered questionnaires of tolerance and satisfaction levels with the treatment were used. Compared with baseline values, reduction of fat thickness was observed by ultrasonography in the posterior thigh area in the G1 group ( P <0.05) and in the buttocks ( P <0.05) and the posterior thigh areas ( P <0.05) in the G2. All the treated areas in both groups showed reduction in cellulite degree in the buttocks, G1 ( P <0.05) and G2 ( P <0.05), and in posterior thigh areas, G1 ( P <0.05) and G2 ( P <0.05). Optimal improvement of skin firmness (G1, P <0.0001; G2, P =0.0034) in the treated areas was observed in both groups. We conclude that the synergistic effects of the Combined Therapy (nonfocused ultrasound plus Aussie current) might be a good option with noninvasive body contouring treatment for improving the aspect of the cellulite, skin firmness and localized fat. If used in association with the whole-body vibratory platform, the results can be better, especially in the treatment of localized fat. Further studies with larger sample size should be performed to confirm these results.

    Fixed orthodontic appliance (FOA) increases the cariogenic microorganisms of mouth including candida. The aim was to evaluate the pharmacodynamic effects of some antibacterial drugs in combination with most applicable antifungal agents on candida isolated from patients with FOA. Three antifungal agents (amphotericin B (AMB), ketoconazole (KET), and itraconazole (ITZ)) and three antibacterial drugs (ciprofloxacin (CIP), doxycycline (DOX), and metronidazole (MET)) with serial concentrations have been used and microdilution broth method has been done for single and combination therapy, then fungal growth was assessed spectrophotometrically, and the combinations were evaluated by bliss independent analysis. According to bliss independent interaction, the synergistic interactions depended on Δ E values that showed the best for CIP was with AMB (Δ E = 55.14) followed with KET (Δ E = 41.23) and lastly ITR (Δ E = 39.67) at CIP = 150 mg/L. DOX was optimal with KET (Δ E = 42.11) followed with AMB (Δ E = 40.77) and the lowest with ITR (Δ E = 9.12) at DOX = 75 mg/L. MET is the best with AMB (Δ E = 40.95) and then with ITR (Δ E = 35.45) and finally KET (Δ E = 15.15) at MET 200 mg/L. Moreover, usage of higher concentrations of antibacterial agents revealed inhibitory effects. This study uncovers the optimum antibiotic combination therapy against cariogenic candida with FOA by usage of low therapeutic concentrations.

    Full Text Available Schizophrenia is one of mental disorders with high cost and lifetime morbidity risk. Hence, it is necessary to analyze the cost-effectiveness of various combinations of antipsychotics. The aim of this study was to analyze the most cost-effective group of antipsychotic combinations in schizophrenia inpatients in West Java Psychiatric Hospital during 2012–2013. Data were collected retrospectively from medical record of patients who used antipsychotics clozapine-haloperidol or clozapine-risperidone therapy. Direct medical costs were obtained from antipsychotics costs, costs of medical treatment, medical expenses, hospitalization costs, and administrative costs. The results showed that the average cost-effectiveness ratio of antipsychotic clozapine-haloperidol was Rp126.898/day and Rp132.781/day for the combination of clozapine-haloperidol and clozapine-risperidone, respectively. Considering length of stay as the therapy effectiveness, it can be concluded that the combination of clozapine-haloperidol is more cost-effective than clozapine-risperidone.

    In this work, we investigated the bystander effect of the tumor and normal cells surrounding the target region caused by radiation-inducible target gene therapy combined with α-particle irradiation. The receptor tumor cell A549 and normal cell MRC-5 were co-cultured with the donor cells irradiated to 0.5 Gy or the non-irradiated donor cells, and their survival and apoptosis fractions were evaluated. The results showed that the combined treatment of Ad-ET and particle irradiation could induce synergistic antitumor effect on A549 tumor cell, and the survival fraction of receptor cells co-cultured with the irradiated cells decreased by 6%, compared with receptor cells co-cultured with non-irradiated cells, and the apoptosis fraction increased in the same circumstance, but no difference was observed with the normal cells. This study demonstrates that Ad-ET combined with α-particle irradiation can significantly cause the bystander effect on neighboring tumor cells by inhibiting cell growth and inducing apoptosis, without obvious toxicity to normal cells. This suggests that combining radiation-inducible TRAIL gene therapy and irradiation may improve tumor treatment efficacy by specifically targeting tumor cells and even involving the neighboring tumor cells.

    The gold standard for the treatment of muscle-invasive bladder cancer Without metastasis is radical cystectomy. However, there increase patients very elderly and with serious complications. They are not good candidates for invasive surgical operation. Intraarterial infusion of 70 mg/m"2 of cisplatin and 30 mg/m"2 of pirarubicin into bilateral bladder arteries was conducted for 5 patients diagnosed with muscle invasive bladder cancers without distant metastasis. Right and left distribution of anti-cancer drugs was determined based on the location of bladder tumor(s). External beam radiation therapy was commenced immediately following intraarterial infusion. The patients were followed up with clinical and radiographic investigations and bladderbiopsy was performed as needed. Patients were all males who are smoking or with smoking history ranging from 73 to 85 years of age (median 82). The duration between transurethral resection of bladder tumors (TUR-Bt) and intraarterial infusion of anti-cancer drugs was 47.4 days (range 26-68), the median follow-up period after intraarterial infusion was 21.5 months (range 87-547) without death. Total radiation dose was 59.2 ±3.0 Gy. Complete remission was accomplished in all cases. One patient showed intravesical recurrence of non muscle-invasive tumors 45.8 months following intraarterial infusion and underwent TUR-Bt. Two cases underwent bladder biopsies showing no tumors. All patients but one case with bladder recurrence were free of tumor recurrence with radiographic investigation. For adverse events, acute renal failure was in one case and leukocytopenia was in all 5 cases, Grade 2 for one and Grade 3 for 4 cases. Follow-up periods are not long enough, but early results of a combination therapy of selective intraarterial anti-cancer drug infusion and radiation therapy for muscle-invasive bladder cancer were good.

    A 68-year-old man was referred to our outpatient clinic with left renal cell cancer and bladder cancer. He had undergone combination therapy comprising chemotherapy plus radiation therapy following radical orchiectomy for testicular cancer at the age of 48 years. The right testis could be felt within the scrotum, however the left testis could not. Blood tests showed no abnormality in regard to testicular tumor markers. Urine cytology was class V. Computed tomography revealed a 3.0 x 3.4 cm mass in the left kidney and a 4.5 x 1.5 cm mass in the left wall of the bladder. We made it a priority to treat the bladder cancer which was strongly suspected to be invasive cancer. At first the patient underwent radical cystectomy. Then left partial nephrectomy was carried out. Our case would appear to be the 24th case of triple primary urogenital cancer in Japan that consisted of left testicular cancer, left renal cancer and bladder cancer. Our case was also thought to be a case of secondary cancer that developed following treatment for testicular cancer. (author)

    Purpose: To develop a method to quantify the therapeutic effect of radiosensitization by hyperthermia; to this end, a numerical method was proposed to convert radiation therapy dose distributions with hyperthermia to equivalent dose distributions without hyperthermia. Methods and Materials: Clinical intensity modulated radiation therapy plans were created for 15 prostate cancer cases. To simulate a clinically relevant heterogeneous temperature distribution, hyperthermia treatment planning was performed for heating with the AMC-8 system. The temperature-dependent parameters α (Gy −1 ) and β (Gy −2 ) of the linear–quadratic model for prostate cancer were estimated from the literature. No thermal enhancement was assumed for normal tissue. The intensity modulated radiation therapy plans and temperature distributions were exported to our in-house-developed radiation therapy treatment planning system, APlan, and equivalent dose distributions without hyperthermia were calculated voxel by voxel using the linear–quadratic model. Results: The planned average tumor temperatures T90, T50, and T10 in the planning target volume were 40.5°C, 41.6°C, and 42.4°C, respectively. The planned minimum, mean, and maximum radiation therapy doses were 62.9 Gy, 76.0 Gy, and 81.0 Gy, respectively. Adding hyperthermia yielded an equivalent dose distribution with an extended 95% isodose level. The equivalent minimum, mean, and maximum doses reflecting the radiosensitization by hyperthermia were 70.3 Gy, 86.3 Gy, and 93.6 Gy, respectively, for a linear increase of α with temperature. This can be considered similar to a dose escalation with a substantial increase in tumor control probability for high-risk prostate carcinoma. Conclusion: A model to quantify the effect of combined radiation therapy and hyperthermia in terms of equivalent dose distributions was presented. This model is particularly instructive to estimate the potential effects of interaction from different treatment

    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).

    Full Text Available Archaeosomes constitute archaeal lipid vesicle vaccine adjuvants that evoke a strong CD8+ T cell response to antigenic cargo. Therapeutic treatment of murine B16-ovalbumin (B16-OVA melanoma with archaeosome-OVA eliminates small subcutaneous solid tumors; however, they eventually resurge despite an increased frequency of circulating and tumor infiltrating OVA-CD8+ T cells. Herein, a number of different approaches were evaluated to improve responses, including dose number, interval, and the combination of vaccine with checkpoint inhibitors. Firstly, we found that tumor protection could not be enhanced by repetitive and/or delayed boosting to maximize the CD8+ T cell number and/or phenotype. The in vivo cytotoxicity of vaccine-induced OVA-CD8+ T cells was impaired in tumor-bearing mice. Additionally, tumor-infiltrating OVA-CD8+ T cells had an increased expression of programmed cell death protein-1 (PD-1 compared to other organ compartments, suggesting impaired function. Combination therapy of tumor-bearing mice with the vaccine archaeosome-OVA, and α-CTLA-4 administered concurrently as well as α-PD-1 and an α-PD-L1 antibody administered starting 9 days after tumor challenge given on a Q3Dx4 schedule (days 9, 12, 15 and 18, significantly enhanced survival. Following multi-combination therapy ~70% of mice had rapid tumor recession, with no detectable tumor mass after >80 days in comparison to a median survival of 17–22 days for untreated or experimental groups receiving single therapies. Overall, archaeosomes offer a powerful platform for delivering cancer antigens when used in combination with checkpoint inhibitor immunotherapies.

    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.

    The object of this study is to evaluate the efficacy of preoperative chemotherapy combined with radiation therapy for bladder cancer. A total of 44 patients with bladder cancer were treated by preoperative chemotherapy combined with radiation therapy between October, 1981 and December, 1986. Clinical stages included 4 patients in Ta, 25 in T1, 11 in T2, and 4 in T3. Each patient was treated twice with 15 gray of radiation to the small pelvic cavity and a chemotherapy combination of adriamycin, cis-platinum, tegaful, and peplomycin. The average observation time after the therapy was 83 month, with the maximum being 146 months. Complete remission was included in 5 patients, partial remission in 27, and no change in 12. Thus, the overall effective rate was 72.8%. Operations, selected by the results of the preoperative therapy, included transurethral resection on 28 patients, transurethral fulguration on 2, partial cystectomy on 4, resection of tumor on 4, and total cystectomy on 3. Operations were not performed on 2 patients and not allowed on 1 patient. The outcome during the long-term follow-up included cancer related deaths in 4 patients, and death resulting from other disorders in 9. The 5-year survival rates for superficial and invasive bladder cancer were 92.4%, and 83.9%, respectively. The 10-year survival rates for superficial and invasive bladder cancer were also 92.4% and 83.9%, respectively. The 3-year and 5-year non-recurrence rates for superficial bladder cancer were 75.8%, and 66.9% respectively, according to the Kaplan-Meier method. On the other hand, the 3-year and 5-year non-recurrence rates for invasive bladder cancer were both 73.8%. During the follow-up between 9 and 11 years, 3 upper tract tumor were diagnosed (2 ureteral cancer, and 1 renal pelvic cancer). We concluded that preoperative chemotherapy combined with radiation therapy may be effective for the treatment of bladder cancer. (author)

    Full Text Available 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.

    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.

    Purpose: To assess the efficacy of balloon dilation combined with chemotherapy and/or radiation therapy for palliation of dysphagia due to malignant esophagogastric junction strictures. Methods: Fluoroscopically guided balloon dilation was attempted in 20 patients. The causes of strictures were gastric adenocarcinoma (n = 10) and esophageal squamous cell carcinoma (n = 10). Scheduled chemotherapy and/or radiation therapy followed balloon dilation in all patients. Results: There were no technical failures or major complications. After balloon dilation, 15 (75%) patients showed improvement of dysphagia. No patient complained of reflux esophagitis during the follow-up period. Among the 15 patients, seven needed no further treatment for palliation of dysphagia until their deaths. The remaining eight patients underwent repeat balloon dilation(n = 4) or stent placement (n = 4)3-43 weeks (mean 15 weeks) after the initial balloon dilation because of recurrent dysphagia. Conclusion: Balloon dilation combined with chemotherapy and/or radiation therapy seems to be an easy and reasonably effective palliative treatment for malignant esophagogastric strictures

    Background and objectives Nowadays, there are several noninvasive technologies being used for improving of body contouring. The objectives of this pilot study were to verify the effectiveness of the Heccus® device, emphasizing the synergism between nonfocused ultrasound plus Aussie current in the improvement of body contour, and to determine if the association of this therapy with whole-body vibration exercises can have additional positive effects in the results of the treatments. Subjects and methods Twenty healthy women aged 20–40 years participated in the study. Ten patients received Combined Therapy treatment (G1) and the other 10 participants received Combined Therapy with additional vibratory platform treatment (G2). Anthropometric and standardized photography analysis, ultrasonography, cutometry and self-adminestered questionnaires of tolerance and satisfaction levels with the treatment were used. Results Compared with baseline values, reduction of fat thickness was observed by ultrasonography in the posterior thigh area in the G1 group (Pcellulite degree in the buttocks, G1 (Ptreatment for improving the aspect of the cellulite, skin firmness and localized fat. If used in association with the whole-body vibratory platform, the results can be better, especially in the treatment of localized fat. Further studies with larger sample size should be performed to confirm these results. PMID:29731654

    With the increasing incidence of cancer worldwide, the need for specific, effective therapies is ever more urgent. One example of targeted cancer therapeutics is hypoxia-activated prodrugs (HAPs), also known as bioreductive prodrugs. These prodrugs are inactive in cells with normal oxygen levels but in hypoxic cells (with low oxygen levels) undergo chemical reduction to the active compound. Hypoxia is a common feature of solid tumors and is associated with a more aggressive phenotype and resistance to all modes of therapy. Therefore, the combination of radiation therapy and bioreductive drugs presents an attractive opportunity for synergistic effects, because the HAP targets the radiation-resistant hypoxic cells. Hypoxia-activated prodrugs have typically been precursors of DNA-damaging agents, but a new generation of molecularly targeted HAPs is emerging. By targeting proteins associated with tumorigenesis and survival, these compounds may result in greater selectivity over healthy tissue. We review the clinical progress of HAPs as adjuncts to radiation therapy and conclude that the use of HAPs alongside radiation is vastly underexplored at the clinical level.

    The aims of this study were to investigate the effect of exercise therapy on the oxidative stress in fibromyalgia patients and relationship between oxidative stress and fibromyalgia symptoms. Thirty women diagnosed with fibromyalgia according to the American College of Rheumatology preliminary criteria, and 23 healthy women whose age- and weight-matched women were enrolled the study. Pain intensity with visual analog scale (VAS), the number of tender points, the fibromyalgia impact questionnaire (FIQ), the Beck depression inventory (BDI) were evaluated. The oxidative stress parameters thiobarbituric acid reactive substances, protein carbonyls, and nitric oxide, and antioxidant parameters thiols and catalase were investigated in patients and control group. After, combined aerobic and strengthen exercise regimen was given to fibromyalgia group. Exercise therapy consisted of a warming period of 10 min, aerobic exercises period of 20 min, muscle strengthening exercises for 20 min, and 10 min cooling down period. Therapy was lasting 1 h three times per week over a 12-week period. All parameters were reevaluated after the treatment in the patient group. The oxidative stress parameters levels were significantly higher, and antioxidant parameters were significantly lower in patients with fibromyalgia than in the controls. VAS, FIQ, and BDI scores decreased significantly with exercise therapy. The exercise improved all parameters of oxidative stress and antioxidant parameters. Also, all clinical parameters were improved with exercise. We should focus on oxidative stress in the treatment for fibromyalgia with the main objective of reducing oxidative load.

    Full Text Available Objectives. To investigate the safety and feasibility of sorafenib neoadjuvant therapy combined with retroperitoneoscopic radical nephrectomy (RRN in treating T2 large renal cell carcinoma (RCC. Methods. Retrospectively analyzed 5 cases (2 males and 3 females, aged 52–73 years of T2 stage large RCC who receive preoperative sorafenib targeted treatment (400 mg bid for 1–3 months and RRN between March, 2013, and July, 2014. Patient information, therapeutic regimen, drug adverse effect, tumor changes before and after surgery, and perioperative parameters were recorded. Results. During the sorafenib therapy adverse effects included 2 cases of hypertension (Grade I toxicity, 1 case of hand-foot syndrome (Grade I, and 1 case of diarrhea (Grade II, which were all tolerable for patients. CT scan and histopathological tests confirmed significant reduction in the longest dimension (LD and medium density (MD of the tumor after therapy as well as tumor hemorrhage, necrosis, and cystic degeneration. All 5 patients received RRN surgery successfully around 2 weeks after drug discontinuation with only 1 case of perioperative complication. Conclusions. Sorafenib neoadjuvant therapy could significantly reduce the size and aggressiveness of T2 large renal tumors, thus reducing the operative challenge and enabling patients who were previously disqualified for operation to receive surgical treatment.

    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 18 F-Fluorodeoxyglucose positron emission tomography/computed tomography ( 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 were similar

    The Virtual Environment for Radiotherapy Training (VERT) system is a recently available tool for radiation therapy education. The majority of research regarding VERT-based education is focused on students, with a growing area of research being VERT's role in patient education. Because large differences in educational requirements exist between students and patients, focused resources and subsequent evaluations are necessary to provide solid justification for the unique benefits and challenges posed by VERT in a patient education context. This commentary article examines VERT's role in patient education, with a focus on salient visual features, VERT's ability to address some of the spatial challenges associated with RT patient education and how to combine technology with human care. © 2018 The Authors.

    In 43 cases of small cell carcinoma of the lung, a combined treatment has been initiated with three drugs (cyclophosphamide 750 mg/m 2 , adriamycin 50 mg/m 2 and vincristine sulphate 1 or 2 mg total dosis), split-course-radiation therapy on the primary tumour (3500 rads) and prophylactic irradiation of the brain (2000 rads). The median survival of the 34 cases evaluable at day 50 attains 253 days. A more favourable evolution is observed for patients with a good response after therapy (median survival: 315 days) and for cases with limited disease (321 days) than for non-responders (median survival: 157 days) and for cases with extensive disease (median survival: 214 days). In spite of tumour site irradiation, prophylactic irradiation of CNS and chemotherapy, there were six local relapses, two CNS extensions and six metastatic relapses and only two autopsied cases without macroscopic evidence of relapse.

    Recent evidence suggests that transcriptional dysregulation may play a role in the pathogenesis of amyotrophic lateral sclerosis (ALS). The histone deacetylase inhibitor, sodium phenylbutyrate (NaPB), is neuroprotective and corrects aberrant gene transcription in ALS mice and has recently been shown to be safe and tolerable in ALS patients while improving hypoacetylation. Since many patients are already on riluzole, it is important to ensure that any proposed therapy does not result in negative synergy with riluzole. The combined treatment of riluzole and NaPB significantly extended survival and improved both the clinical and neuropathological phenotypes in G93A transgenic ALS mice beyond either agent alone. Combination therapy increased survival by 21.5%, compared to the separate administration of riluzole (7.5%) and NaPB (12.8%), while improving both body weight loss and grip strength. The data show that the combined treatment was synergistic. In addition, riluzole/NaPB treatment ameliorated gross lumbar and ventral horn atrophy, attenuated lumbar ventral horn neuronal cell death, and decreased reactive astrogliosis. Riluzole/NaPB administration increased acetylation at H4 and increased NF-kappaB p50 translocation to the nucleus in G93A mice, consistent with a therapeutic effect. These data suggest that NaPB may not interfere with the pharmacologic action of riluzole in ALS patients.

    Full Text Available Type 2 diabetes mellitus (T2DM management is complex, with few patients successfully achieving recommended glycemic targets with monotherapy, most progressing to combination therapy, and many eventually requiring insulin. Sodium glucose cotransporter 2 (SGLT2 inhibitors are an emerging class of antidiabetes agents with an insulin-independent mechanism of action, making them suitable for use in combination with any other class of antidiabetes agents, including insulin. This review evaluates a 78-week, randomized, double-blind, placebo-controlled trial investigating the impact of empagliflozin, an SGLT2 inhibitor, as add-on to basal insulin in patients with inadequate glycemic control on basal insulin, with or without metformin and/or a sulfonylurea. Empagliflozin added on to basal insulin resulted in significant and sustained reductions in glycated hemoglobin (HbA1c levels compared with placebo. Empagliflozin has previously been shown to induce weight loss, and was associated with sustained weight loss in this study. This combination therapy was well tolerated, with similar levels of hypoglycemic adverse events in the empagliflozin and placebo groups over the 78-week treatment period. Urinary tract infections and genital infections, side effects associated with SGLT2 inhibitors, were reported more commonly in the empagliflozin group; however, such events led to treatment discontinuation in very few patients. These findings suggest that, with their complementary mechanisms of action, empagliflozin added on to basal insulin may be a useful treatment option in patients on basal insulin who need additional glycemic control without weight gain.

    Purpose To assess the efficacy and safety of switching from prostaglandin analog (PGA) monotherapy to tafluprost/timolol fixed-combination (Taf/Tim) therapy. Subjects and Methods Patients with primary open-angle glaucoma, normal-tension glaucoma, or ocular hypertension who had received PGA monotherapy for at least 3 months were enrolled. Patients were examined at 1, 2, and 3 months after changing therapies. Subsequently, the patients were returned to PGA monotherapy. The examined parameters included intraocular pressure (IOP) and adverse events. A questionnaire survey was conducted after the switch to Taf/Tim therapy. Results Forty patients with a mean age of 66.5 ± 10.3 years were enrolled; 39 of these patients completed the study protocol. Switching to Taf/Tim significantly reduced the IOP from 18.2 ± 2.6 mmHg at baseline to 14.8 ± 2.5 mmHg at 1 month, 15.2 ± 2.8 mmHg at 2 months, and 14.9 ± 2.5 mmHg at 3 months (P Taf/Tim reduced the pulse rate insignificantly. No significant differences were observed in blood pressure, conjunctival hyperemia, or corneal adverse events. A questionnaire showed that the introduction of Taf/Tim did not significantly influence symptoms. Conclusions Compared with PGA monotherapy, Taf/Tim fixed-combination therapy significantly reduced IOP without severe adverse events. PMID:29675274

    PURPOSE: To examine the acute toxicity and outcome in patients (pts) treated with combined modality therapy following resection of adenocarcinoma of the pancreas. MATERIALS AND METHODS: From 2/88 to 2/96, 34 pts (M:20, F:14) received postoperative combined modality therapy following a pancreatic resection. Tumor location included; head only: 28, head and ampulla: 1, ampulla only: 1, body and tail: 2, and tail only: 2. Postoperative stages included: stage I: 7 (21%) and stage III: 27 (79%). Pts were referred for combined modality therapy based on surgeon preference. In general, pts were treated who had one or more adverse prognostic factors. These included positive local/regional lymph nodes (79%), positive margins (50%) or disease invasive into adjacent structures (85 %). Radiation fields included the original primary tumor bed (based on preoperative CT scans) and peri-pancreatic and para-aortic lymph nodes adjacent to vertebral bodies T10 through L3. No attempt was made to include the entire pancreas in the radiation field. Patients received 5040 cGy at 180 cGy/day using a 3 or 4 field technique and CT-based treatment planning. Concurrent bolus 5-FU (375-500 mg/m 2 ) was delivered on the first three and last three days of radiation. Post-radiation maintenance bolus 5-FU was given to 7 patients for a median of 6 cycles. A toxicity assessment using the NCI toxicity criteria was performed at each weekly visit and 4 weeks following the completion of combined modality therapy. The median follow-up was 13 months (range: 2-36 months). Patterns of failure as a component of failure were assessed by radiographic criteria and, in 2 pts, by intraoperative evaluation for symptomatic progression of disease. Local/regional failure was defined as recurrence within the radiation field. Distant failure included liver, peritoneal seeding, and extra-abdominal sites. Actuarial survival was calculated from the time of surgery using the Kaplan-Meier method. RESULTS: The only grade 3

    Full Text Available The purpose of this study was to investigate the influence of the invasion process and different strategies of treatment on some biochemical blood indices of mice infested with Syphacia obvelata and Trichocephalus muris of gastrointestinal tract, in order to optimize etiotropic therapy and improve its efficiency. Materials and methods. In the experiment were used albino mice, divided into the following groups: intact animals (control group; animals infected with Syphacia obvelata; animals infected with Trichocephalus muris; infected animals, who received a single dose of albendazole (7 mg/kg; infected animals, who received a single dose of albendazole (7 mg/kg and gamavit dose intramuscularly (0.3 cm3/kg simultaneously. Blood for the studies was taken from the animals at 1, 3, 7, 10, 14, 17, 21 days after the infection and after drug administration. From biochemical parameters were determined activities of next enzymes: alanine aminotransferase (ALT, aspartate aminotransferase (AST, gamma-glutamyl transferase (γ-GTP and alkaline phosphatase (AP – with kinetic method IFCC. Results. Infecting animals with helminthes caused a noticeable increase in AP and gamma-GTP levels and cytolytic activity of enzymes: ALT and AST compared with intact group. The above-mentioned complex of metabolic changes clearly reveals a disturbance in hepatocyte metabolism that leads to the decrease in detoxifying function of the liver. This can be apparently explained with toxic effects of helminthes waste products. Albendazole mono-therapy in the therapeutic dose (7 mg/kg of mice infected with both Syphacia and Trichocephalus caused an even greater increase in ALT and AST levels and also increased serum levels of alkaline phosphatase and γ-GTP, compared with the control and infected animals, that clearly shows an additional toxic effect from the antihelmintic drug. The use of albendazole in combination with a complex antioxidant “Gamavit” in animals infected with

    We observed the effects of physical rehabilitation therapy combined with medication on pelvic floor dysfunction (PFD). We collected the medical records of 84 maternal patients with PFD who received treatment at the Affiliated Hospital of Hebei University between May 2015 and October 2016. These patients were randomly divided into two groups, the control group (n=42) and observation group (n=42). In the control group, patients received conventional physical rehabilitation therapy while in observation group, patients received the shixiao powder combined with siwu decoction in addition to the physical rehabilitation. The therapeutic effects were compared between the two groups. The total effective rate of the observation group was 97.6%, which was significantly higher than 78.6% in the control group (Ppelvic floor function under rest state, such as electromyo-graphy amplitude, contraction force, coordinate strength and urine flow rate, were significantly higher than those in control group (P0.05). In observation group, after treatment, the rehabilitation effects of urinary incontinence and sexual life quality at 3 months post-delivery were significantly better than those in control group (P0.05), however, after treatment, the levels of CRP and IL-10 of patients in observation group were significantly lower than those in control group (Pphysical rehabilitation therapy combined with the shixiao powder and siwu decoction exhibits significant efficacy in the treatment of PFD by effectively improving the pelvic floor functions, increasing perineal muscle strength, and decreasing expression levels of inflammatory factors, which can significantly ameliorate life quality and reduce the incidence rate of complications. Thus, this treatment method shows great application value in clinical practice.

  12. 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

    PURPOSE Cognitive impairment after critical illness is common and debilitating. We developed a cognitive therapy program for critically ill patients and assessed the feasibility and safety of administering combined cognitive and physical therapy early during a critical illness. METHODS We randomized 87 medical and surgical ICU patients with respiratory failure and/or shock in a 1:1:2 manner to three groups: usual care, early once-daily physical therapy, or early once-daily physical therapy plus a novel, progressive, twice-daily cognitive therapy protocol. Cognitive therapy included orientation, memory, attention, and problem solving exercises, and other activities. We assessed feasibility outcomes of the early cognitive plus physical therapy intervention. At 3-months, we also assessed cognitive, functional and health-related quality of life outcomes. Data are presented as median [interquartile range] or frequency (%). RESULTS Early cognitive therapy was a delivered to 41/43 (95%) of cognitive plus physical therapy patients on 100% [92–100%] of study days beginning 1.0 [1.0–1.0] day following enrollment. Physical therapy was received by 17/22 (77%) of usual care patients, by 21/22 (95%) of physical therapy only patients and 42/43 (98%) of cognitive plus physical therapy patients on 17% [10–26%], 67% [46–87%] and 75% [59–88%] of study days, respectively. Cognitive, functional and health-related quality of life outcomes did not differ between groups at 3-month follow-up. CONCLUSIONS This pilot study demonstrates that early rehabilitation can be extended beyond physical therapy to include cognitive therapy. Future work to determine optimal patient selection, intensity of treatment and benefits of cognitive therapy in the critically ill is needed. PMID:24257969

    Combining narrowband UVB (NB-UVB) phototherapy with biologics has been shown to enhance the therapeutic response of plaque psoriasis patients. The objective of this study was to evaluate the effectiveness of apremilast combined with NB-UVB in patients with moderate to severe plaque psoriasis. This was a 12-week, open-label study of 29 patients diagnosed with moderate to severe psoriasis. Patients received apremilast 30 mg twice daily, and increasing doses of NB-UVB (310-312 nm) 3 times per week for 12 weeks. Twenty-two of 29 patients (76%) completed the 12-week apremilast and NB-UVB combination therapy; 73% (16 of 22 completers) achieved a PASI 75 response at week 12. Mean scores for PASI, VAS pain, VAS itch, DLQI, and PGA improved by 77%, 77%, 69%, 70%, and 67%, respectively, at week 12. The most commonly reported adverse events (AEs) were mild and moderate first-degree burns related to NB-UVB (n=11 [38%] patients). A second-degree NB-UVB burn was reported (likely due to an underlying photosensitivity) and was considered a serious AE. The combination of apremilast with NB-UVB was effective for the treatment of moderate to severe plaque psoriasis, without any unexpected safety signals. Apremilast combined with NB-UVB provided a high treatment response in patients with moderate to severe plaque psoriasis, and may be an option for patients to enhance a patient's initial therapeutic response.

    34 patients operated on for malignant gliomas were successively treated by combination chemotherapy with VM 26 and CCNU and conventional radiation therapy with an average dosage of 5,800 rads, six months after surgery. The general and haematological tolerance of delayed irradiation after chemotherapy was satisfactory. Twelve patients developed neurological complications during or after irradiation. The complications were early in 10 cases, and delayed in 2. They were probably due to tumour growth in five cases, and secondary to irradiation in seven. In four of the seven cases the preradiation chemotherapy seemed to potentiate the radiation effect on the central nervous system. (author)

    Full Text Available 2.6% of pancreatic cancer patients have the primary manifestation of gastrointestinal bleeding. It is not feasible to stop the duodenal hemorrhage caused by the pancreatic cancer infiltration. A 43-year-old woman who was diagnosed as having pancreatic cancer with multiple hepatic metastases and duodenal infiltration was administered gemcitabine and S-1 combination therapy. During the chemotherapy, initially, bleeding occurred due to duodenal infiltration. However, we continued the chemotherapy and duodenal infiltration was markedly reduced in size and did not rebleed. Aggressive chemotherapy contributed to maintenance of performance status as well as improvement of quality of life for the patient.

    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

    2005-01-01

    Purpose: Photodynamic therapy (PDT) can be designed to target either tumor vasculature or tumor cells by varying the drug-light interval. Photodynamic therapy treatments with different drug-light intervals can be combined to increase tumor response by targeting both tumor vasculature and tumor cells. The sequence of photosensitizer and light delivery can influence the effect of combined treatments. Methods and materials: The R3327-MatLyLu rat prostate tumor model was used in this study. Photosensitizer verteporfin distribution was quantified by fluorescence microscopy. Tumor blood flow changes were monitored by laser-Doppler system and tumor hypoxia was quantified by the immunohistochemical staining for the hypoxic marker EF5. The therapeutic effects of PDT treatments were evaluated by the histologic examination and tumor regrowth assay. Results: Fluorescence microscopic studies indicated that tumor localization of verteporfin changed from predominantly within the tumor vasculature at 15 min after injection, to being throughout the tumor parenchyma at 3 h after injection. Light treatment (50 J/cm 2 ) at 15 min after verteporfin injection (0.25 mg/kg, i.v.) induced significant tumor vascular damage, as manifested by tumor blood flow reduction and increase in the tumor hypoxic fraction. In contrast, the vascular effect observed after the same light dose (50 J/cm 2 ) delivered 3 h after administration of verteporfin (1 mg/kg, i.v.) was an initial acute decrease in blood flow, followed by recovery to the level of control. The EF5 staining revealed no significant increase in hypoxic fraction at 1 h after PDT using 3 h drug-light interval. The combination of 3-h interval PDT and 15-min interval PDT was more effective in inhibiting tumor growth than each individual PDT treatment. However, it was found that the combined treatment with the sequence of 3-h interval PDT before 15-min interval PDT led to a superior antitumor effect than the other combinative PDT treatments

    Full Text Available Insomnia is defined as a disorder of difficulty initiating sleep, difficulty maintaining sleep, sleep is not fresh during 1 month or more that makes a significant clinical disturbance or distress. Insomnia affects 15% to 40% of world general population and predominantly in women 65 to 79 years. Insomnia also reported in individuals aged 18 to 34 years. If neglected for a long time, insomnia can diminish job performance and quality of live for each individuals. The new strategy to solve this problem in the future is combining pharmacotherapy like eszopiclone a nonbenzodiazepine derivate and mind-body therapy (MBT to the patients. It can lowering severe risk of conventional drugs side effects, but from pharmacoeconomic this drug is not costly effective. It must combine with MBT to decrease frequency and duration of drug consumption.

    Ghana changed their antimalarial drug policy from monotherapies to Artemisinin-based Combination Therapies in 2004 in order to provide more efficacious medicines for treatment of malaria. The policy change can be eroded if poor quality Artemisinin-based Combination Therapies are allowed to remain on the Ghanaian market unchecked by regulatory bodies and law enforcement agencies. The presence and prevalence of substandard and counterfeit Artemisinin-based Combination Therapies need to be determined on open markets in Ghana; a review of the current policy; identifying any gaps and making recommendations on actions to be taken in addressing gaps identified are essential as the data provided and recommendations made will help in ensuring effective control of malaria in Ghana. A field survey of antimalarial drugs was conducted in the central part of Ghana. The amount of active pharmaceutical ingredient in each Artemisinin-based Combination Therapy sample identified in the survey was measured using high performance liquid chromatographic analyses. Active pharmaceutical ingredient within the range of 85-115 % was considered as standard and active pharmaceutical ingredient results out of the range were considered as substandard. All samples were screened to confirm stated active pharmaceutical ingredient presence using mass spectrometry. A total of 256 Artemisinin-based Combination Therapies were purchased from known medicine outlets, including market stalls, hospitals/clinics, pharmacies, drug stores. Artemether lumefantrine (52.5 %) and artesunate amodiaquine (43.2 %) were the predominant Artemisinin-based Combination Therapies purchased. Of the 256 Artemisinin-based Combination Therapies purchased, 254 were tested, excluding two samples of Artesunate-SP. About 35 % of Artemisinin-based Combination Therapies were found to be substandard. Nine percent of Artemisinin-based Combination Therapies purchased were past their expiry date; no counterfeit (falsified) medicine

    Combined treatment with interpersonal psychotherapy (IPT) and antidepressants (ADs) has been found more effective than single pharmacotherapy in patients with major depression and concomitant borderline personality disorder (BPD). The aim of our study is to investigate whether combined treatment with a modified version of IPT is still superior to ADs when treating patients with a single diagnosis of BPD. Fifty-five consecutive outpatients with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, diagnosis of BPD were enrolled. They were randomly assigned to 2 treatment arms for 32 weeks: fluoxetine 20 to 40 mg per day plus clinical management; and fluoxetine 20 to 40 mg per day plus IPT adapted to BPD (IPT-BPD). Eleven patients (20%) discontinued treatment owing to noncompliance. Forty-four patients completed the treatment period. They were assessed at baseline, and at week 16 and 32 with: a semi-structured interview for demographic and clinical variables; Clinical Global Impression Scale (CGI-S); Hamilton Depression Rating Scale (HDRS); Hamilton Anxiety Rating Scale (HARS); Social and Occupational Functioning Assessment Scale (SOFAS); BPD Severity Index (BPD-SI); and a questionnaire for quality of life (Satisfaction Profile [SAT-P]). A univariate general linear model was performed with 2 factors: duration and type of treatment. P values of less than 0.05 were considered significant. Remission rates did not differ significantly between subgroups. Duration, but not type of treatment, had a significant effect on CGI-S, HDRS, SOFAS, and total BPD-SI score changes. Combined therapy was more effective on the HARS; the items: interpersonal relationships, affective instability, and impulsivity of BPD-SI; and the factors: psychological functioning and social functioning of SAT-P. Combined therapy with adapted IPT was superior to fluoxetine alone in BPD patients, concerning a few core symptoms of the disorder, anxiety, and quality of life.

    2013-01-01

    Background Dipeptidyl peptidase-4 (DPP-4) inhibitors modulate incretin hormones and exert anti-diabetic effects in type 2 diabetes mellitus. Treatment with angiotensin II type 1 receptor blockers (ARB) is a proven successful intervention for hypertension with type 2 diabetes. The present study investigated the combined effects of the DPP-4 inhibitor vildagliptin and the ARB valsartan in a mouse model of type 2 diabetes. Methods C57BL/6 J mice fed with high-fat diet (HFD) or db/db mice were treated with placebo, phloridzin (PHZ), vildagliptin alone (ViL), valsartan alone (VaL) or ViL with VaL (ViLVaL) for 8 weeks. Results Glucose metabolism was improved in response to PHZ, ViL and ViLVaL in both HFD and db/db mice. Upon glucose challenge, ViLVaL showed the greatest suppression of blood glucose excursions, with increased insulin secretion, in db/db mice. ViLVaL treatment also showed an improvement of insulin sensitivity in db/db mice. Serum inflammatory cytokines were significantly decreased, and adiponectin was highest, in the ViLVaL group. ViLVaL improved insulin signaling and attenuated stress signaling in liver with amelioration of hepatic steatosis due to activated fatty acid oxidation in db/db mice. Furthermore, immunohistochemical analysis of the pancreas revealed that the combination treatment resulted in an increased expression of insulin and PDX-1, and increased insulin content. Conclusions The combination therapy of ViL and VaL improves both pancreatic beta-cell function and insulin sensitivity, with a reduction of the inflammatory and cell stress milieu in mouse models of T2DM. Our results suggest that this combination therapy exerts additive or even synergistic benefits to treat T2DM. PMID:24188631

    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.

    Treatment was studied of oro-facial epidermoid carcinoma by combined chemo- and radiotherapy and eventual surgery. Cytostatic drugs were applied intraarterially. After a monocytostatic treatment trial with Methotrexate (MTX), a combined cytostatic program was developed alternating two cytostatic drugs, viz., MTX and Bleomycin (BLM). The usefulness of chemotherapy and its inclusion in the treatment of epidermoid carcinoma in the oro-facial region was found justified for combined therapy. The selected intraarterial administration, however, is not suitable for routine application. For this reason, the combination irradiation or surgical therapy with chemotherapy was adopted.

    Purpose To report the effects of combined onabotulinumtoxinA (Botox) injections and myofascial release physical therapy on myofascial pelvic pain (MFPP) by comparing pre- and posttreatment average pelvic pain scores, trigger points, and patient self-reported pelvic pain. Secondary outcomes were to examine posttreatment complications and determine demographic differences between patients with/without an improvement in pain. Materials and Methods This was an Institutional Review Board approved retrospective case series on women over 18 years with MFPP who received Botox and physical therapy between July 2006 and November 2014. Presence of trigger points and pelvic pain scores were determined by digital palpation of the iliococcygeus, puborectalis, obturator internus, and rectus muscles. Average pelvic pain scores (0–10) reflected an average of the scores obtained from palpation of each muscle. Self-reported improvement in pain was recorded as yes/no. Results Fifty women met the inclusion/exclusion criteria. Posttreatment, patients had lower average pelvic pain scores (3.7±4.0 vs. 6.4±1.8, p=0.005), and fewer trigger points (44% vs. 100%, pphysical therapy under anesthesia can be effective in treating women with chronic pelvic pain secondary to MFPP.

    Palliative radiotherapy is often required for patients with metastatic malignant melanoma in the case of bone or brain metastases. Since BRAF inhibitor therapy is highly efficient in V600-mutated melanomas, there is hesitation to stop it during radiotherapy. Consequently, radiotherapy under simultaneous vemurafenib treatment is frequently needed. We report the case of a patient receiving palliative radiotherapy of spinal bone metastases before and during vemurafenib therapy. The skin reactions were quantitatively scored using computer-assisted digital image evaluation. Radiotherapy without vemurafenib was tolerated very well, whereas radiotherapy under simultaneous vemurafenib treatment resulted in accentuated skin reactions. Furthermore, the patient developed dysphagia and had to be hospitalized for parenteral nutrition. In the quantitative analysis, there was a twofold increase in pigmentation and erythema of the irradiated skin area of the thoracic spine when vemurafenib was combined with radiotherapy compared with radiotherapy treatment alone. This is the first reported case of a patient showing no complications during radiotherapy without vemurafenib but remarkable skin and mucosal toxicity under concurrent vemurafenib therapy. Thus, a genetically conditioned individually elevated radiosensitivity can definitely be excluded. Compared with other reported cases, radiosensitization was not limited to the skin, but also affected the esophageal mucosa. Vemurafenib is a strong radiosensitizer. Patients receiving radiotherapy under simultaneous vemurafenib treatment should be monitored very closely. (orig.) [de

    Cancer immunotherapies are dramatically reshaping the clinical management of oncologic patients. For many of these therapies, the guidelines for administration, monitoring, and management of associated toxicities are still being established. This is especially relevant for adoptively transferred, genetically-modified T cells, which have unique pharmacokinetic properties, due to their ability to replicate and persist long-term, following a single administration. Furthermore, in the case of CAR-T cells, the use of synthetic immune receptors may impact signaling pathways involved in T cell function and survival in unexpected ways. We, herein, comment on the most salient aspects of CAR-T cell design and clinical experience in the treatment of solid tumors. In addition, we discuss different possible scenarios for combinations of CAR-T cells and other treatment modalities, with a special emphasis on kinase inhibitors, elaborating on the strategies to maximize synergism. Finally, we discuss some of the technologies that are available to explore the molecular events governing the success of these therapies. The young fields of synthetic and systems biology are likely to be major players in the advancement of CAR-T cell therapies, providing the tools and the knowledge to engineer patients' T lymphocytes into intelligent cancer-fighting micromachines.

    Full Text Available Abstract Cellular therapy for spinal cord injury (SCI is overviewed focusing on bone marrow mononuclear cells, olfactory ensheathing cells, and mesenchymal stem cells. A case is made for the possibility of combining cell types, as well as for allogeneic use. We report the case of 29 year old male who suffered a crush fracture of the L1 vertebral body, lacking lower sensorimotor function, being a score A on the ASIA scale. Stem cell therapy comprised of intrathecal administration of allogeneic umbilical cord blood ex-vivo expanded CD34 and umbilical cord matrix MSC was performed 5 months, 8 months, and 14 months after injury. Cell administration was well tolerated with no adverse effects observed. Neuropathic pain subsided from intermittent 10/10 to once a week 3/10 VAS. Recovery of muscle, bowel and sexual function was noted, along with a decrease in ASIA score to "D". This case supports further investigation into allogeneic-based stem cell therapies for SCI.

    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.

    Full Text Available External therapy with topical steroids is used for a long time. To date topical glucocorticosteroids (TGCS are in the leading position in dermatology among all medicines for external therapy. TGCS as a powerful tool of pathogenic action can rapidly reduce or decrease inflammatory changes in the skin and eliminate subjective symptoms of dermatoses (itching, burning. their positive effect lead to the rehabilitation of working ability and daily living activity, positively affect the psychoemotional state and significantly improve the patient’s quality of life. Urea in dermatology has been used for a very long time, as it softens the skin, reduces its dryness and eliminates peeling. In recent decades interest in this compound has intensified after a formation of an idea about natural moisturizing factor (NMF - a complex of substances (which includes urea being a part of the intercellular matrix of the epidermis and capable of retaining the water in the epithelial layer of the skin necessary for its normal functioning. The article presents modern literature data on the reasoning of the inclusion of a combination of topical glucocorticosteroids with urea in a complex therapy of steroid-responsive dermatoses.

    Full Text Available Aim: to assess the efficacy and tolerability of low-dose iodine therapy compared with the combination of iodine and levothyroxine in endemic goitre patients. Methods: 12-month prospective study was performed, in which 81 patients were randomized on two groups: Group 1 (n = 40 - KI (200 micrograms/day and Group 2 (n = 41 - KI (100 mcg/day + L-T4 (1.0 mcg/kg. Thyroid volume, TSH and Anti-TPO-Ab levels were evaluated at baseline, at 8 month of the treatment and at 12 month (4 month after the cessation of the therapy. Results: the significant decreasing of thyroid volumes was found in group 1 at 8 month compared with baseline (20.5 ml at baseline and 16,4 ml at 8 month р < 0.001. After the therapy cessation the further benefit of a sustained effect was demonstrated (16.4 ml at 8 month and 16.1 ml at 12 month, р = 0.31. Iodine-induced hypo- and hyperthyroidism were not observed. High Anti-TPO-Ab level was found in one of 31 patients (3%. In group 2 significant difference between thyroid volumes was found at 8 month compared with baseline (20,5 ml at baseline and 16.2 ml at 8 month р < 0.001. The sustained effect was revealed at least 4 month after the therapy cessation (16.2 ml at 8 month and 16.1 ml at 12 month, р = 0.77. One man had iodine-induced subclinical hyperthyroidism. Anti-TPO-Ab was not detected in this group. No significant difference between thyroid volume decreasing, TSH and Anti-TPO-Ab levels in two comparable groups was observed. Conclusion: KI alone (200 mcg/day or the combination of L-T4 (1.0 mcg/kg and KI (100 mcg/day are equally effective and tolerable for endemic goitre therapy.

    Full Text Available BACKGROUND: Drug resistance in Plasmodium falciparum poses a major threat to malaria control. Combination antimalarial therapy including artemisinins has been advocated recently to improve efficacy and limit the spread of resistance, but artemisinins are expensive and relatively untested in highly endemic areas. We compared artemisinin-based and other combination therapies in four districts in Uganda with varying transmission intensity. METHODS AND FINDINGS: We enrolled 2,160 patients aged 6 mo or greater with uncomplicated falciparum malaria. Patients were randomized to receive chloroquine (CQ + sulfadoxine-pyrimethamine (SP; amodiaquine (AQ + SP; or AQ + artesunate (AS. Primary endpoints were the 28-d risks of parasitological failure either unadjusted or adjusted by genotyping to distinguish recrudescence from new infections. A total of 2,081 patients completed follow-up, of which 1,749 (84% were under the age of 5 y. The risk of recrudescence after treatment with CQ + SP was high, ranging from 22% to 46% at the four sites. This risk was significantly lower (p < 0.01 after AQ + SP or AQ + AS (7%-18% and 4%-12%, respectively. Compared to AQ + SP, AQ + AS was associated with a lower risk of recrudescence but a higher risk of new infection. The overall risk of repeat therapy due to any recurrent infection (recrudescence or new infection was similar at two sites and significantly higher for AQ + AS at the two highest transmission sites (risk differences = 15% and 16%, p < 0.003. CONCLUSION: AQ + AS was the most efficacious regimen for preventing recrudescence, but this benefit was outweighed by an increased risk of new infection. Considering all recurrent infections, the efficacy of AQ + SP was at least as efficacious at all sites and superior to AQ + AS at the highest transmission sites. The high endemicity of malaria in Africa may impact on the efficacy of artemisinin-based combination therapy. The registration number for this trial is ISRCTN

    Background Excessive iron accumulation leads to iron toxicity in the brain; however the underlying mechanism is unclear. We investigated the effects of iron overload induced by high iron-diet consumption on brain mitochondrial function, brain synaptic plasticity and learning and memory. Iron chelator (deferiprone) and antioxidant (n-acetyl cysteine) effects on iron-overload brains were also studied. Methodology Male Wistar rats were fed either normal diet or high iron-diet consumption for 12 weeks, after which rats in each diet group were treated with vehicle or deferiprone (50 mg/kg) or n-acetyl cysteine (100 mg/kg) or both for another 4 weeks. High iron-diet consumption caused brain iron accumulation, brain mitochondrial dysfunction, impaired brain synaptic plasticity and cognition, blood-brain-barrier breakdown, and brain apoptosis. Although both iron chelator and antioxidant attenuated these deleterious effects, combined therapy provided more robust results. Conclusion In conclusion, this is the first study demonstrating that combined iron chelator and anti-oxidant therapy completely restored brain function impaired by iron overload. PMID:24400127

    Red blood cells (RBCs)-based vesicles have been widely used for drug delivery due to their unique advantages. Intact RBCs contain a large amount of oxyhemoglobin (oxyHb), which can assist with photodynamic therapy (PDT). Indocyanine green (ICG), a photosensitizer both for photothermal therapy (PTT) and PDT, shows potent anticancer efficacy when combined with chemotherapeutic drug doxorubicin (DOX). In this study, we prepared nanoscaled RBCs (RAs) containing oxyHb and gas-generating agent ammonium bicarbonate (ABC) for co-loading and controlled release of ICG and DOX, thus hoping to achieve synergistic effects of PTT/PDT and chemotherapy against breast cancer. Compared to free ICG, ICG and DOX co-loaded RAs (DIRAs) exhibited nearly identical PTT efficiency both in vitro and in vivo, but meanwhile their PDT efficiency was enhanced significantly. In mouse breast cancer cells, DIRAs significantly inhibited cell growth and induced cell apoptosis after laser irradiation. In breast tumor-bearing mice, intratumoral injection of DIRAs and followed by local laser irradiation almost completely ablated breast tumor and further suppressed tumor recurrence and metastasis. In conclusion, this biomimetic multifunctional nanosystem can facilitate breast cancer treatment by combining PTT/PDT and chemotherapy. Copyright © 2017 Elsevier Ltd. All rights reserved.

  4. Effectiveness of a positive psychology intervention combined with cognitive behavioral therapy in university students

    Directory of Open Access Journals (Sweden)

    Rosario-Josefa Marrero

    Full Text Available The aim of this study was to design and implement a positive intervention combined with cognitive-behavioral therapy to enhance subjective and psychological well-being and other positive functioning constructs in a convenience sample. Participants analysed were 48 university students (mean age 22.25, 25 assigned nonrandomized to intervention condition and 23 to no-treatment waiting-list control condition. All participants were assessed pre- and post-intervention to test the treatment program effectiveness. Repeated-measures ANCOVAs, controlling baseline differences between the two groups, indicated that the intervention group reported greater social support after the intervention period than the waiting-list control group. Within-group differences were found for happiness, selfacceptance, positive relations with others, optimism, and self-esteem in the intervention group; these differences did not appear in the waiting-list control group. These findings suggest the limited capacity of this intervention program for improving well-being through positive activities combined with cognitive-behavioral therapy. Future research should analyse what kind of activities could be more effective in promoting well-being depending on the characteristics of participants.

  5. Treatment of vitiligo vulgaris with the combination therapy of topical steroid and vitamin D3 compound

    2012-06-01

    Full Text Available We reported here two cases of vitiligo vulgaris successfully treated with the combination therapy of topical steroid and vitamin D3 compound and currently maintained by vitamin D3 analog without any adverse effects: skin atrophy, striae or telangiectasia on the exposed areas. The best-known mechanism of topical vitamin D3 analog is the enhancement of keratinocytes differentiation and anti-proliferative effects. Vitamin D3 analog is also reported to suppress T-cell mediated immunity, T-cell skin recruitment, and skin infiltration via down-regulating cutaneous lymphocyte antigen expression. Furthermore, vitamin D3 compounds are known to influence melanocyte maturation and differentiation and also to up-regulate melanogenesis. Autoreactive lymphocytes against melanocytes are one of the causes. Topical vitamin D3 analog may control vitiligo itself, however stronger immunosuppressive effects of topical corticosteroid may contribute to rapid re-pigmentation suppressing auto-reactive lymphocytes. The topical combination therapy is a simple, effective and safe option for vitiligo vulgaris in sun-exposed areas.

    A highly sensitive second generation HCV core antigen assay has recently been developed. We compared viral disappearance and kinetics data between commercially available core antigen assays, Lumipulse Ortho HCV Ag, and a quantitative HCV RNA PCR assay, Cobas Amplicor HCV Monitor Test, Version 2 to estimate the predictive benefit of sustained viral response (SVR) and non-SVR in 59 patients treated with interferon and ribavirin combination therapy. We found a good correlation between HCV core Ag and HCV RNA level regardless of genotype. Although the sensitivity of the core antigen assay was lower than PCR, the dynamic range was broader than that of the PCR assay, so that we did not need to dilute the samples in 59 patients. We detected serial decline of core Ag levels in 24 hrs, 7 days and 14 days after interferon combination therapy. The decline of core antigen levels was significant in SVR patients compared to non-SVR as well as in genotype 2a, 2b patients compared to 1b. Core antigen-negative on day 1 could predict all 10 SVR patients (PPV = 100%), whereas RNA-negative could predict 22 SVR out of 25 on day 14 (PPV = 88.0%). None of the patients who had detectable serum core antigen on day 14 became SVR(NPV = 100%), although NPV was 91.2% on RNA negativity. An easy, simple, low cost new HCV core antigen detecting system seems to be useful for assessing and monitoring IFN treatment for HCV.

    Keloids were characterized by excessive growth of fibrous tissues, and shared several pathological characteristics with cancer. They did put physical and emotional stress on patients in that keloids could badly change appearance of patients. N-(4-hydroxyphenyl) retinamide (4HPR) showed cytotoxic activity on a wide variety of invasive-growth cells. Our work was aim to prepare N-(4-hydroxyphenyl) retinamide-loaded lipid microbubbles (4HPR-LM) combined with ultrasound for anti-keloid therapy. 4HPR-loaded liposomes (4HPR-L) were first prepared by film evaporation method, and then 4HPR-LM were manufactured by mixing 4HPR-L and perfluoropentane (PFP) with ultrasonic cavitation method. The mean particle size and entrapment efficiency 4HPR-LM were 113 nm and 95%, respectively. The anti-keloids activity of 4HPR-LM was assessed with BALB/c nude mice bearing subcutaneous xenograft keloids model. 4HPR-LM, combined with ultrasound, could significantly induce apoptosis of keloid fibroblasts in vitro and inhibited growth of keloids in vivo. Thus, 4HPR-LM could be considered as a promising agent for anti-keloids therapy.

    We devised new combination therapy of radiation and local administration of OK-432 and performed for 26 patients with esophageal cancer between March, 1987 and December, 1988 as a pilot study. The average age was 73 years. Among 26 patients, males were 20 and females were six. Patients were irradiated at the schedule of under 2 Gy/day and the dose of TDF (time, dose and fractionation factor) 100 totally. OK-432, 10KE was endoscopically administered around cancer lesion at the beginning of the radiotherapy, and two weeks later, 5KE was given in the same manner. Complete response was obtained in 20 out of 26 cases (77%) and partial response was obtained in the remaining six cases (23%). All six patients with tumor length less than five cm showed complete response. All 16 patients who could not eat food orally before treatment, became to take food enough orally after the treatment and could discharge in good condition. One year and two years survival rate of 26 patients by Kaplan Meier method were 67.4% and 47.2%, respectively. Six patients with tumor length less than five cm, are all alive without a sign of recurrence. This combination therapy will improve not only the response rate and the survival rate, but also the quality of life of patients with esophageal cancer. (author)

    Cancer cells contain multiple genetic changes in cell signaling pathways that drive abnormal cell survival, proliferation, invasion, and metastasis. Unfortunately, patients treated with single agents inhibiting only one of these pathways--even if showing an initial response--often develop resistance with subsequent relapse or progression of their cancer, typically via the activation of an alternative uninhibited pathway. Combination therapies offer the potential for inhibiting multiple targets and pathways simultaneously to more effectively kill cancer cells and prevent or delay the emergence of drug resistance. However, there are many unique challenges to developing combination therapies, including devising and applying appropriate preclinical tests and clinical trial designs, prioritizing which combination therapies to test, avoiding overlapping toxicity of multiple agents, and overcoming legal, cultural, and regulatory barriers that impede collaboration among multiple companies, organizations, and/or institutions. More effective strategies to efficiently develop combination cancer therapies are urgently needed. Thus, the Institute of Medicine's National Cancer Policy Forum recently convened a workshop with the goal of identifying barriers that may be impeding the development of combination investigational cancer therapies, as well as potential solutions to overcome those barriers, improve collaboration, and ultimately accelerate the development of promising combinations of investigational cancer therapies. ©2012 AACR.

    Multiple treatment strategies are available for empiric antibiotic therapy in hospitals, but neither clinical studies nor theoretical investigations have yielded a clear picture when which strategy is optimal and why. Extending earlier work of others and us, we present a mathematical model capturing treatment strategies using two drugs, i.e the multi-drug therapies referred to as cycling, mixing, and combination therapy, as well as monotherapy with either drug. We randomly sample a large parameter space to determine the conditions determining success or failure of these strategies. We find that combination therapy tends to outperform the other treatment strategies. By using linear discriminant analysis and particle swarm optimization, we find that the most important parameters determining success or failure of combination therapy relative to the other treatment strategies are the de novo rate of emergence of double resistance in patients infected with sensitive bacteria and the fitness costs associated with double resistance. The rate at which double resistance is imported into the hospital via patients admitted from the outside community has little influence, as all treatment strategies are affected equally. The parameter sets for which combination therapy fails tend to fall into areas with low biological plausibility as they are characterised by very high rates of de novo emergence of resistance to both drugs compared to a single drug, and the cost of double resistance is considerably smaller than the sum of the costs of single resistance.

    Controlling effects of drugs administered in combination is particularly challenging with a densified regimen because of life-threatening hematological toxicities. We have developed a mathematical model to optimize drug dosing regimens and to redesign the dose intensification-dose escalation process, using densified cycles of combined anticancer drugs. A generic mathematical model was developed to describe the main components of the real process, including pharmacokinetics, safety and efficacy pharmacodynamics, and non-hematological toxicity risk. This model allowed for computing the distribution of the total drug amount of each drug in combination, for each escalation dose level, in order to minimize the average tumor mass for each cycle. This was achieved while complying with absolute neutrophil count clinical constraints and without exceeding a fixed risk of non-hematological dose-limiting toxicity. The innovative part of this work was the development of densifying and intensifying designs in a unified procedure. This model enabled us to determine the appropriate regimen in a pilot phase I/II study in metastatic breast patients for a 2-week-cycle treatment of docetaxel plus epirubicin doublet, and to propose a new dose-ranging process. In addition to the present application, this method can be further used to achieve optimization of any combination therapy, thus improving the efficacy versus toxicity balance of such a regimen.

    Carnosic acid is a phenolic diterpene with anti-inflammation, anticancer, anti-bacterial, anti-diabetic, as well as neuroprotective properties, which is generated by many species from Lamiaceae family. Fisetin (3,3',4',7-tetrahydroxyflavone), a naturally flavonoid is abundantly produced in different vegetables and fruits. Fisetin has been reported to have various positive biological effects, including anti-proliferative, anticancer, anti-oxidative and neuroprotective effects. Lung cancer is reported as the most common neoplasm in human world-wide. In the present study, the possible benefits of carnosic acid combined with fisetin on lung cancer in vitro and in vivo was explored. Carnosic acid and fisetin combination led to apoptosis in lung cancer cells. Caspase-3 signaling pathway was promoted in carnosic acid and fisetin co-treatment, which was accompanied by anti-apoptotic proteins of Bcl-2 and Bcl-xl decreasing and pro-apoptotic signals of Bax and Bad increasing. The death receptor (DR) of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) was enhanced in carnosic acid and fisetin combined treatment. Furthermore, the mouse xenograft model in vivo suggested that carnosic acid and fisetin combined treatment inhibited lung cancer growth in comparison to the carnosic acid or fisetin monotherapy. This study supplies a novel therapy to induce apoptosis to inhibit lung cancer through caspase-3 activation.

    In an effort to improve tumor control by radiation therapy, a treatment regimen consisting of concurrent combination of bleomycin (90 mg/3 weeks) and radiation (30 Gy/3 weeks) was applied. Between 1972 and 1981, 287 patients with squamous cell carcinoma in the oral cavity were subjected to this bleomycin-radiation combination regimen. All except 4 patients experienced marked response after treatment using the bleomycin-radiation combination alone. One hundred thirty-four patients (47 %) obtained CR and 149 (53 %) PR. Higher CR rates were obtained in patients with carcinoma of the lower gum (62 %), of the upper gum (68 %), and of the cheek mucosa (43 %), compared to patients with carcinoma of the floor of the mouth (21 %), and of the tongue (15 %). In each of the tumor sites, small lesions (T1, T2) obtained higher CR rates, compared with large lesions (T3, T4). Of the 134 patients who experienced CR, 83 were observed without any further treatment after bleomycin-radiation combination alone. Local recurrence-free rates of these patients were 72 % for T1, T2 lesions and 48 % for T3, T4 lesions. Local control rates were increased to 85 % and 78 %, respectively, with successful salvage treatment involving surgery or interstitial radiotherapy for post-irradiation failures. (author)

    Context • Interest has been rising in the use of complementary and alternative medicine (CAM) for the promotion of health and treatment of disease. To date, the majority of CAM research has focused on exploring the demographic characteristics, attitudes, and motivations of CAM users and on the efficacy of different therapies and products. Less is known with respect to the psychological characteristics of people who use CAM. Previous research has not investigated the usefulness of integrating mind-body therapies with natural products in a combined mood intervention. Objective • The study intended to investigate attitudes toward a proposed new approach to the treatment of mood, one that integrates psychological mind-body therapies and natural nutritional products. Design • Participants completed an online survey covering demographics, personality traits, locus of control, use of CAM, attitudes toward the proposed psychonutritional approach, and mood. Setting • This study was conducted at the University of Adelaide School of Psychology (Adelaide, SA, Australia). Participants • Participants were 333 members of the Australian general public, who were recruited online via the social-media platform Facebook. The majority were women (83.2%), aged between 18 and 81 y. Outcome Measures • Measures included the Multidimensional Health Locus of Control Scale Form B, the Ten-Item Personality Inventory, and the Depression, Anxiety and Stress Scale. Results • Participants were positive about the proposed approach and were likely to try it to enhance their moods. The likeliness of use of the combined approach was significantly higher in the female participants and was associated with higher levels of the personality trait openness and an internal health locus of control, after controlling for all other variables. Conclusions • Interest exists for an intervention for mood that incorporates both psychological and nutritional approaches. Further research into the

    Because of the longstanding controversy regarding whether hypothyroid patients can be optimally replaced by treatment with levothyroxine (L-T4) alone, numerous studies have addressed potential benefits of combined therapy of triiodothyronine (T3) with L-T4. Results of these studies have failed to support a potential benefit of combined therapy. A strong argument for the addition of L-T3 to L-T4 monotherapy has been lacking until recent genetic studies indicated a rationale for such therapy among a small fraction of the hypothyroid patient population. Interest in this issue has focused on the importance of the deiodinases in maintaining the euthyroid state and the role of genetic polymorphisms in the deiodinase genes that would affect thyroid hormone concentrations in both blood and tissues. One such polymorphism in the D2 gene, Thr92Ala, is associated with reduced T4 to T3 activation in skeletal muscle and thyroid, linked to obesity and alterations in thyroid-pituitary feedback, and in responses to thyroid hormone treatment. Although our professional organizations continue to recommend L-T4 alone for the treatment of hypothyroidism, the possibility of a D2 gene polymorphism should be considered in patients on L-T4 monotherapy who continue to complain of fatigue in spite of dosage achieving low normal serum thyroid stimulating hormone levels. A suggestive clue to the presence of this polymorphism could be a higher than normal free T4/free T3 ratio. Clinicians could consider adding T3 as a therapeutic trial in selected patients. Future well controlled clinical trials will be required to more fully resolve the controversy.

    Twenty-three patients with invasive bladder cancer (T2 in 17, T3 in 6) were treated initially with combined intraarterial cisplatin infusion and radiation therapy. Cisplatin (50 mg) was infused into the internal iliac artery through a subcutaneous reservoir twice a week over three weeks while concurrent radiation therapy with 30 Gy, delivered in 15 fractions, was given. In 23 patients, 6 received additional cisplatin infusion and the other 17 had transurethral resection of bladder tumor (TURBT). Two of the patients undergoing total cystectomy exhibited a complete response (CR). Thus overall response rate was 87% (CR in 13 and partial response in 7). CR was achieved in 53% for T2 patients and 67% for T3 patients. CR was slightly higher in patients with non-papillary cancer than those with papillary one. Toxic reaction included a decrease in bladder capacity in 2 patients and severe diarrhea due to methicillin-resistant Staphylococcus aureus colitis in one. The other toxicities, including nausea, vomiting, neurotoxicity and myelosuppression, were tolerable. All except for one are alive. Seven patients had a local recurrence of bladder cancer. One patient developed invasive bladder cancer reaching the prostatic urethra. One other patient had recurrence at the same site as the previous tumor. Five others had superficial bladder cancer and were managed by TURBT. Bladder function was preserved in 65% at a mean follow-up of 29 months. In conclusion, the combined intraarterial cisplatin infusion and radiation therapy is useful for the initial treatment of invasive bladder cancer. (N.K.)

    Objective: To explore the anti-tumor effects of Egr-IFNgamma gene therapy combined with {sup 125}I-UdR radionuclide therapy in mice bearing H22 hepatocarcinoma and its mechanism. Methods: The recombinant plasmid pcDNAEgr-IFNgamma mixed with liposome was injected into tumor. 48 h later, 370 kBq {sup 125}I-UdR was injected into tumor. The tumor growth rates at different times were observed. After 3 d gene-radionuclide therapy, the concentration of IFNgamma in cytoplasm of H22 cells and cytotoxic activities of splenic CTL of the mice in different groups were examined. Results: The tumor growth rates of pcDNAEgr-IFNgamma + {sup 125}I-UdR group were obviously lower than those of control group, {sup 125}I-UdR group and pcDNAEgr-1 + {sup 125}I-UdR group 6-15 d after gene-radionuclide therapy. IFNgamma protein was found in cytoplasm of H22 cells in pcDNAEgr-IFNgamma + {sup 125}I-UdR group after 3 d gene-radionuclide therapy. Cytotoxic activity of splenic CTL in pcDNAEgr-IFNgamma + {sup 125}I-UdR group was significantly higher than that in the other groups (P<0.01). Conclusions: The anti-tumor effects in vivo of pcDNAEgr-IFNgamma gene therapy combined with {sup 125}I-UdR radionuclide therapy are better than those of {sup 125}I-UdR therapy. (authors)

    Objective: To test the hypothesis that p53 gene therapy combined with endostatin can enhance tumor response to radiation therapy of RM-1 mouse xenograft prostate cancer and to investigate its mechanism. Methods: A mouse prostate cancer model was established. Then mice with xenograft tumor were randomly divided into group A (control), B (radiation), C (radiation and rAdp53), D (radiation and rh-endostatin) and E (radiation and rAdp53 and rhendostatin). On day 1, rAdp53 was injected intra-tumorously with 1 x 10 10 vp per animal to group C and E. From day 1 to 14, rh-endostatin was given 15 mg/kg intraperitoneally daily to group D and E. On day 4 single fraction of 15 Gy was given to tumors in groups B, C, D and E. Normal saline was injected intra-tumorously or intraperitoneaUy accordingly as control. No treatment was done to group A. Tumor volume was measured daily. Samples were collected on Days 5, 10 and 15. Ki67, CD31, p53 and VEGF were detected by means of immunohistochemistry. Results: (1) Radiation alone, radiation combined with intra-tumorous injection of Adp53 and/or intraperitoneal injection of rhendostatin resulted in tumor growth arrest of RM-1 cells in vivo (P = 0.000). Radiation combined with both rAdp53 and rhendostatin was the most effective treatment (P < 0.05). (2) All the four treatment groups had a decreased expression of mutant type P53 (P = 0.000). The expression of Ki67 in groups B and C were equal (P 0.05) and increasing (P = 0.000), respectively. Group D had a up-down-up curve (P < 0.05), but group E had a up-down one. On day 5 the expresion of VEGF in group E was the lowest (P < 0.05). An increased expression of MVD compared with the control was shown, and MVD in groups C, D and E were always higher than that in the control (P < 0.05). Conclusions: The limitation of radiotherapy could be overcome by combination with beth p53 gene therapy and endostatin on the growth of mouse prostate cancer cell. Radiation, rAdp53 and endostatin have their

We compared the efficacy and safety of risperidone monotherapy versus combination therapy of haloperidol with sertaline for the acute treatment of schizoaffective disorder, depressed type. This is an open label study of 52 female inpatients randomly assigned to risperidone alone (N = 26 or haloperidol in combination with sertraline (N = 26 for 12 weeks. The mean daily doses of medications were: risperidone: 3.75–3.29 mg/day, haloperidol: 5.35–4.15 mg/day, sertraline: 65.39–133.82 mg/day. Efficacy was measured using clinical rating scales of treatment, safety, and tolerability. Risperidone patients showed statistically significant greater improvement than haloperidol-sertraline patients on efficacy measures including Positive and Negative Syndrome Scale and Clinical Global Impressions rating. A higher number of risperidone patients dropped out of the study early. Fewer adverse events and lesser need for concomitant medications occurred in patients on risperidone. The risperidone group showed better psychological, social and occupational functioning (Global Assessment of Functioning and higher quality of life (Heinrich’s Quality of Life Scale. Risperidone has higher antipsychotic efficacy and tolerability compared with haloperidol-sertraline combination for the acute treatment of schizoaffective disorder, depressed type. Both treatments were comparable in terms of antidepressant efficacy.Keywords: schizoaffective disorder, depressed type

    Combination effect of lentinan with X-ray irradiation on the metastatic mouse tumors, L1210, KLN205 and Lewis lung carcinoma were studied. Combination use of lentinan with X-ray therapy prolonged the life of BDF/sub 1/ mice bearing L1210 leukemia in the suitable combination conditions. Combination effects of lentinan with X-ray therapy were also observed on the suppression of the growth of KLN205 squamus cell carcinoma and on the suppression of the metastasis of Lewis lung carcinoma. Especially, in the case that lentinan was administered before or after X-ray local irradiation in the pulmorary metastasis system of Lewis lung carcinoma, a marked suppressin of pulmonary metastasis was observed and 2 to 4 mice among 8 tested mice were tumor free.

    Full Text Available Abstract Background Standard chemotherapy protocols in NSCLC are of limited clinical benefit. Histone deacetylase (HDAC inhibitors represent a new strategy in human cancer therapy. In this study the combination of the HDAC inhibitor phenylbutyrate (PB and the nucleoside analogue gemcitabine (GEM was evaluated and the mechanisms underlying increased cell death were analyzed. Methods Dose escalation studies evaluating the cytotoxicity of PB (0.01–100 mM, GEM (0.01–100 μg/ml and a combination of the two were performed on two NSCLC cell lines (BEN and KNS62. Apoptotic cell death was quantified. The involvement of caspase-dependent cell death and MAP-kinase activation was analyzed. Additionally, mitochondrial damage was determined. In an orthotopic animal model the combined effect of PB and GEM on therapy was analyzed. Results Applied as a single drug both GEM and PB revealed limited potential to induce apoptosis in KNS62 and Ben cells. Combination therapy was 50–80% (p = 0.012 more effective than either agent alone. On the caspase level, combination therapy significantly increased cleavage of the pro-forms compared to single chemotherapy. The broad spectrum caspase-inhibitor zVAD was able to inhibit caspase cleavage completely, but reduced the frequency of apoptotic cells only by 30%. Combination therapy significantly increased changes in MTP and the release of cyto-c, AIF and Smac/Diabolo into the cytoplasm. Furthermore, the inhibitors of apoptosis c-IAP1 and c-IAP2 were downregulated and it was shown that in combination therapy JNK activation contributed significantly to induction of apoptosis. The size of the primary tumors growing orthotopically in SCID mice treated for 4 weeks with GEM and PB was significantly reduced (2.2–2.7 fold compared to GEM therapy alone. The Ki-67 (KNS62: p = 0.015; Ben: p = 0.093 and topoisomerase IIα (KNS62: p = 0.008; Ben: p = 0.064 proliferation indices were clearly reduced in tumors treated by combination

Historically, treatment options for melanoma brain metastases (MBM have predominantly consisted of surgery and radiotherapy. While these options can help provide local control, the majority of patients still develop intracranial progression. Indeed, novel therapeutic options, including molecularly targeted agents and immunotherapy, have improved outcomes and are now changing the role of radiotherapy. Up to 50% of melanomas contain an activating BRAF mutation, resulting in hyperactive cellular proliferation and survival. Drugs that target BRAF have been introduced for the treatment of metastatic melanoma and offer hope in improving disease outcomes; however, many of these trials either excluded or had a limited amount of patients with MBM. Recent studies have revealed that melanoma cell lines become more radiosensitive following BRAF inhibition, thus providing a potential synergistic mechanism when combining BRAF inhibitor (BRAFi and radiotherapy. However, neurotoxicity concerns also exist with this combination. This article reviews the efficacy and limitations of BRAFi therapy for MBM, describes current evidence for combining BRAFis with radiation, discusses the rationale and evidence for combination modalities, and highlights emerging clinical trials specifically investigating this combination in MBM.

    Palliative radiotherapy is often required for patients with metastatic malignant melanoma in the case of bone or brain metastases. Since BRAF inhibitor therapy is highly efficient in V600-mutated melanomas, there is hesitation to stop it during radiotherapy. Consequently, radiotherapy under simultaneous vemurafenib treatment is frequently needed. We report the case of a patient receiving palliative radiotherapy of spinal bone metastases before and during vemurafenib therapy. The skin reactions were quantitatively scored using computer-assisted digital image evaluation. Radiotherapy without vemurafenib was tolerated very well, whereas radiotherapy under simultaneous vemurafenib treatment resulted in accentuated skin reactions. Furthermore, the patient developed dysphagia and had to be hospitalized for parenteral nutrition. In the quantitative analysis, there was a twofold increase in pigmentation and erythema of the irradiated skin area of the thoracic spine when vemurafenib was combined with radiotherapy compared with radiotherapy treatment alone. This is the first reported case of a patient showing no complications during radiotherapy without vemurafenib but remarkable skin and mucosal toxicity under concurrent vemurafenib therapy. Thus, a genetically conditioned individually elevated radiosensitivity can definitely be excluded. Compared with other reported cases, radiosensitization was not limited to the skin, but also affected the esophageal mucosa. Vemurafenib is a strong radiosensitizer. Patients receiving radiotherapy under simultaneous vemurafenib treatment should be monitored very closely. (orig.) [German] Bei Patienten mit metastasiertem Melanom ist die palliative Bestrahlung von Knochen- oder Hirnmetastasen haeufig erforderlich.

    The purpose of this study was to investigate the potential of combining cytosine deaminase/5-fluorocytosine (CD/5-FC) gene therapy and radiation therapy (either external beam radiation or radioimmunotherapy [RIT]), for the treatment of prostate cancer. Tumor xenografts of CD-transduced LNCaP cells grown in the testes of severe combined immunodeficiency (SCID) mice were used to evaluate antitumor effect. The mice were injected intraperitoneally with 500 mg/kg of 5-FC, or with 5, 15 or 30 mg/kg of 5-fluorouracil (5-FU), for 9 days. The tumors were treated with fractionated radiation at a dose of 1 or 3 Gy/day for 3 days, or I-131 labelled anti-prostate specific antigen (anti-PSA) monoclonal antibody (mAb) administration at a subtherapeutic dose of 20 or 80 {mu}Ci. Intratumoral and serum concentrations of 5-FU were measured using high performance liquid chromatography. Mice treated with CD/5-FC gene therapy presented a significant tumor growth inhibition comparable to that obtained with 15 mg/kg, 5-FU systemic administration without marked weight loss. Treatment with CD/5-FC gene therapy resulted in higher tumor but lower serum concentrations of 5-FU than treatment with systemic 5-FU chemotherapy. An additive antitumor effect was obtained when CD/5-FC therapy was combined with 1 Gy irradiation, which by itself did not produce a significant antitumor effect. However, the efficacy of CD/5-FC therapy was not enhanced when combined with RIT, probably due to poor accumulation of the mAb as the tumor/blood ratio never exceeded 1. These findings indicate that CD/5-FC gene therapy for prostate cancer may function with enhanced antitumor effect when combined with external beam radiation. However, combining CD/5-FC gene therapy and RIT using an anti-PSA mAb may not be effective because of insufficient accumulation of the mAb at the target tumors. (author)

    The purpose of this study was to investigate the potential of combining cytosine deaminase/5-fluorocytosine (CD/5-FC) gene therapy and radiation therapy (either external beam radiation or radioimmunotherapy [RIT]), for the treatment of prostate cancer. Tumor xenografts of CD-transduced LNCaP cells grown in the testes of severe combined immunodeficiency (SCID) mice were used to evaluate antitumor effect. The mice were injected intraperitoneally with 500 mg/kg of 5-FC, or with 5, 15 or 30 mg/kg of 5-fluorouracil (5-FU), for 9 days. The tumors were treated with fractionated radiation at a dose of 1 or 3 Gy/day for 3 days, or I-131 labelled anti-prostate specific antigen (anti-PSA) monoclonal antibody (mAb) administration at a subtherapeutic dose of 20 or 80 μCi. Intratumoral and serum concentrations of 5-FU were measured using high performance liquid chromatography. Mice treated with CD/5-FC gene therapy presented a significant tumor growth inhibition comparable to that obtained with 15 mg/kg, 5-FU systemic administration without marked weight loss. Treatment with CD/5-FC gene therapy resulted in higher tumor but lower serum concentrations of 5-FU than treatment with systemic 5-FU chemotherapy. An additive antitumor effect was obtained when CD/5-FC therapy was combined with 1 Gy irradiation, which by itself did not produce a significant antitumor effect. However, the efficacy of CD/5-FC therapy was not enhanced when combined with RIT, probably due to poor accumulation of the mAb as the tumor/blood ratio never exceeded 1. These findings indicate that CD/5-FC gene therapy for prostate cancer may function with enhanced antitumor effect when combined with external beam radiation. However, combining CD/5-FC gene therapy and RIT using an anti-PSA mAb may not be effective because of insufficient accumulation of the mAb at the target tumors. (author)

Combination of photothermal and photodynamic therapy (PTT/PDT with chemotherapy offers unique advantages over monotherapy alone. However, free drugs, such as photosensitizers and chemotherapeutic agents, lack tumor-targeted accumulation and can be easily eliminated from the body. Moreover, most of the PTT drugs are hydrophobic and their organic solvents have in vivo toxicity, thereby limiting their potential in clinical translation. Herein, simple multifunctional nanoparticles (NPs using IR780 (a near-infrared dye and docetaxel (DTX-loaded nanoplatform based on human serum albumin (HSA (HSA@IR780@DTX was developed for targeted imaging and for PTT/PDT with chemotherapy for the treatment of castration-resistant prostate cancer treatment. In this platform, HSA is a biocompatible nanocarrier that binds to both DTX and IR780. DTX and IR780, as hydrophobic drug, can induce the self-assembly of HSA proteins. Transmission electron microscopic imaging showed that NPs formed by self-assembly are spherical with a smooth surface with a hydrodynamic diameter of 146.5±10.8 nm. The cytotoxicity of HSA@IR780@DTX NPs with or without laser irradiation in prostate cancer cells (22RV1 was determined via CCK-8 assay. The antitumor effect of HSA@IR780@DTX plus laser irradiation was better than either HSA@IR780@DTX without laser exposure or single PTT heating induced by HSA@IR780 NPs under near-infrared laser, suggesting a significant combined effect in comparison to monotherapy. Near-infrared fluorescence imaging showed that HSA@IR780@DTX NPs could preferentially

While a combination of telmisartan and a calcium channel blocker is often used to achieve a target BP level, the metabolic effects of this drug combination remain unclear. Therefore, this study evaluated the metabolic effects of telmisartan plus nifedipine controlled release (CR therapy, in hypertensive patients without metabolic disease.Methods: Sixteen patients with essential hypertension, who had not undergone antihypertensive therapy in the previous 6 months, were studied. Patients were initiated on telmisartan (40 mg/day. If their office BP was not reduced to 140/90 mmHg after 6 weeks, nifedipine CR (20–40 mg per day was added for 18 weeks.

    In order to guide the antimalarial treatment policy of Somalia, we conducted therapeutic efficacy studies of routinely used antimalarial monotherapies as well as artemisinin-based combination therapies (ACTs) for uncomplicated malaria in three sentinel sites during 2003-2006. Therapeutic efficacy of chloroquine (CQ), amodiaquine (AQ) and sulfadoxine/pyrimetahmine (SP) monotherapies, and artesunate plus SP (AS+SP) or AQ (AS+AQ) were evaluated in children 6 months to 10 years old with uncomplicated malaria. For the assessment of the monotherapies, 2003 WHO protocol with 14-day follow-up was used while the 2005 WHO protocol with 28-day follow-up was used for testing the ACTs. Of the monotherapies, CQ performed very poorly with treatment failures varying from 76.5% to 88% between the sites. AQ treatment failure was low except for Janale site with treatment failure of 23.4% compared to 2.8% and 8% in Jamame and Jowhar, respectively. For SP, treatment failures from 7.8% to 12.2% were observed. A 28-day test of artemisinin-based combinations, AS+SP and AS+AQ, proved to be highly efficacious with cure rates of 98-100% supporting the choice of AS+SP combination as first line treatment for uncomplicated malaria for Somalia.

    Kleptomania is characterized by repetitive stealing of things not needed for personal use. Comorbidity with affective disorders, personality disorders and attention deficit hyperactivity disorder (ADHD) is often described. Pharmacological treatment options are serotonin reuptake inhibitors, naltrexone or mood stabilizers. There are no controlled studies for cognitive-behavioral (CBT) and psychodynamic psychotherapies. However, literature suggests that patients respond to CBT, especially when combined with pharmacological strategies. Dialectical behavioral therapy (DBT) is successfully applied in the treatment of borderline personality disorder. and, in a modified manner, of ADHD. We report a treatment of an in-patient with kleptomania, depressive episode, combined personality disorder and ADHD. Under combined treatment with DBT, which has been successfully used in the treatment of impulsive disorders, and duloxetine, the patient's urge to steal decreased markedly, and no corresponding actions were detectable in follow-up examinations. Particularly for the kleptomania subtype with comorbid ADHD and / or personality disorder, DBT may be a promising approach. In addition, duloxetine as a serotonin-epinephrine reuptake inhibitor (SNRI) might fit into a complementary treatment strategy.

    Highly relevant mouse models of human neuroblastoma (NB) are needed to evaluate new therapeutic strategies against NB. In this study, we characterized transgenic mice with bilateral adrenal tumors. On the basis of information from the tumoral gene expression profiles, we examined the antitumor effects of unencapsulated and liposomal doxorubicin (DXR), alone and in combination with gefitinib, on adrenal NB. We showed that intravenous injection of unencapsulated or liposomal DXR alone inhibited tumor growth in a dose-dependent manner, as assessed by magnetic resonance imaging (MRI). However, liposomal DXR did not exhibit greater antitumor effect than unencapsulated DXR. Immunohistochemical analysis revealed that the adrenal tumor vasculature with abundant pericyte coverage was a less leaky structure for liposomes. Combination therapy with unencapsulated or liposomal DXR plus gefitinib strongly suppressed tumor growth and delayed tumor regrowth than treatment with unencapsulated or liposomal DXR alone, even at a lower dose of DXR. Dynamic contrast-enhanced MRI analysis revealed that gefitinib treatment increased blood flow in the tumor, indicating that gefitinib treatment changes the tumor vascular environment in a manner that may increase the antitumor effect of DXR. In conclusion, the combination of gefitinib and DXR induces growth inhibition of adrenal NBs in transgenic mice. These findings will provide helpful insights into new treatments for NB

    Benign prostatic hyperplasia (BPH) is a frequent cause of lower urinary symptoms, with a prevalence of 50% by the sixth decade of life. Hyperplasia of stromal and epithelial prostatic elements that surround the urethra cause lower urinary tract symptoms (LUTS), urinary tract infection and acute urinary retention. Medical treatments of symptomatic BPH include; 1) the 5α-reductase inhibitors, 2) the α1-adrenergic antagonists, and 3) the combination of a 5α-reductase inhibitor and a α1-adrenergic antagonist. Selective α1-adrenergic antagonists relax the smooth muscle of the prostate and bladder neck without affecting the detrussor muscle of the bladder wall, thus decreasing the resistance to urine flow without compromising bladder contractility. Clinical trials have shown that α1-adrenergic antagonists decrease LUTS and increase urinary flow rates in men with symptomatic BPH, but do not reduce the long-term risk of urinary retention or need for surgical intervention. Inhibitors of 5α-reductase decrease production of dihydrotestosterone within the prostate resulting in decreased prostate volumes, increased peak urinary flow rates, improvement of symptoms, and decreased risk of acute urinary retention and need for surgical intervention. Interim results of the ongoing Combination of Avodart and Tamsulosin (CombAt) study have shown combination therapy with the 5α-reductase inhibitor dutasteride and the α1-adrenergic antagonist tamsulosin offer significant improvements from baseline compared with either drug alone.

    To evaluate the methods and major outcomes of transcranial direct current stimulation (tDCS) combined with virtual reality (VR) therapy in randomized controlled trials. A systematic review was performed following PRISMA guidelines using PubMed, PubMed Central, Web of Science and CAPES periodic databases, with no time restriction. The studies were screened for the following inclusion criteria: human subjects, combination of VR and tDCS methods, and randomized controlled study design. All potentially relevant articles were independently reviewed by two researchers, who reached a consensus on which articles met the inclusion criteria. The PEDro scale was used to evaluate the studies. Eleven studies were included, all of which utilized a variety of tDCS and VR application methods. The main outcomes were found to be beneficial in intervention groups of different populations, including improvements in body sway, gait, stroke recovery, pain management and vegetative reactions. The use of tDCS combined with VR showed positive results in both healthy and impaired patients. Future studies with larger sample sizes and homogeneous participants are required to confirm the benefits of tDCS and VR. Implications for Rehabilitation tDCS with VR intervention can be an alternative to traditional rehabilitation programs. tDCS with VR is a promising type of intervention with a variety of positive effects. Application of tDCS with VR is appropriated to both healthy and impaired patients. There is no consensus of tDCS with VR application.

    The objective of the present study was to evaluate the efficacy of combination of endovascular graft exclusion and drugs for hypertension/hyperglycemia for the treatment of abdominal aortic aneurysm (AAA). We analyzed 156 patients with AAA. Eighty-four patients were hypertensive and 72 were hyperglycemic. After endovascular graft exclusion, hypertensive patients were divided into four groups and treated with cyclopenthiazide, reserpine, propranolol, and placebo respectively. Hyperglycemic patients were divided into three groups and treated with metformin, insulin, and placebo respectively. Body temperature and peripheral blood leukocytes were measured at day 1, 2, 7, and 14 after endovascular graft exclusion. Size of AAAs, blood pressure, and blood sugar were measured again after 1 year. In hypertensive patients, the size of AAAs reduced after endovascular graft exclusion, while the combined treatments with cyclopenthiazide, reserpine, or propranolol helped to reduce blood pressure (blood pressure decrease AAA size decreased in the control group (PAAAs reduced after endovascular graft exclusion. Combined treatment with Metformin and Insulin reduced blood sugar (control, blood sugar >7.8 mmol/L (22/24), AAA size (P7.8 mmol/L (14/24), AAA size (P7.8 mmol/L (11/24), AAA size (PAAA therapy.

    Full Text Available Abstract Background The combination of spinal manipulation and various physiotherapeutic procedures used to correct the curvatures associated with scoliosis have been largely unsuccessful. Typically, the goals of these procedures are often to relax, strengthen, or stretch musculotendinous and/or ligamentous structures. In this study, we investigate the possible benefits of combining spinal manipulation, positional traction, and neuromuscular reeducation in the treatment of idiopathic scoliosis. Methods A total of 22 patient files were selected to participate in the protocol. Of these, 19 met the study criterion required for analysis of treatment benefits. Anteroposterior radiographs were taken of each subject prior to treatment intervention and 4–6 weeks following the intervention. A Cobb angle was drawn and analyzed on each radiograph, so pre and post comparisons could be made. Results After 4–6 weeks of treatment, the treatment group averaged a 17° reduction in their Cobb angle measurements. None of the patients' Cobb angles increased. A total of 3 subjects were dismissed from the study for noncompliance relating to home care instructions, leaving 19 subjects to be evaluated post-intervention. Conclusions The combined use of spinal manipulation and postural therapy appeared to significantly reduce the severity of the Cobb angle in all 19 subjects. These results warrant further testing of this protocol.

    Purpose: To report the preliminary results of a Phase I/II study combining radiotherapy and in situ gene therapy (adenovirus/herpes simplex virus thymidine kinase gene/valacyclovir) with or without hormonal therapy in the treatment of prostate cancer. Methods and Materials: Arm A: low-risk patients (T1-T2a, Gleason score <7, pretreatment PSA <10) were treated with combined radio-gene therapy. A mean dose of 76 Gy was delivered to the prostate with intensity-modulated radiotherapy. Arm B: high-risk patients (T2b-T3, Gleason score ≥7, pretreatment PSA ≥10) were treated with combined radio-gene therapy and hormonal therapy. Hormonal therapy was comprised of a 4-month leuprolide injection and 2-week use of flutamide. Arm C: Stage D1 (positive pelvic lymph node) patients received the same regimen as Arm B, with the additional 45 Gy to the pelvic lymphatics. Treatment-related toxicity was assessed using Cancer Therapy Evaluation Program common toxicity score and Radiation Therapy Oncology Group (RTOG) toxicity score. Results: Thirty patients (13 in Arm A, 14 in Arm B, and 3 in Arm C) completed the trial. Median follow-up was 5.5 months. Eleven patients (37%) developed flu-like symptoms (Cancer Therapy Evaluation Program Grade 1) of fatigue and chills/rigors after gene therapy injection but recovered within 24 h. Four patients (13%) and 2 patients (7%) developed Grade 1 and 2 fever, respectively. There was no patient with weight loss. One patient in Arm B developed Grade 3 elevation in liver enzyme, whereas 11 and 2 patients developed Grade 1 and 2 abnormal liver function tests. There was no Grade 2 or above hematologic toxicity. Three patients had transient rise in creatinine. There was no RTOG Grade 3 or above lower gastrointestinal toxicity. Toxicity levels were as follows: 4 patients (13%), Grade 2; 6 patients (20%), Grade 1; and 20 patients (67%), no toxicity. There was 1 patient with RTOG Grade 3 genitourinary toxicity, 12 patients (40%) with Grade 2, 8 patients

    Purpose: To explore long-term immune responses after combined radio-gene-hormonal therapy. Methods and Materials: Thirty-three patients with prostate specific antigen 10 or higher or Gleason score of 7 or higher or clinical stage T2b to T3 were treated with gene therapy that consisted of 3 separate intraprostatic injections of AdHSV-tk on Days 0, 56, and 70. Each injection was followed by 2 weeks of valacyclovir. Intensity-modulated radiation therapy was delivered 2 days after the second AdHSV-tk injection for 7 weeks. Hormonal therapy was initiated on Day 0 and continued for 4 months or 2.3 years. Blood samples were taken before, during, and after treatment. Lymphocytes were analyzed by fluorescent antibody cell sorting (FACS). Results: Median follow-up was 26 months (range, 4-48 months). The mean percentages of DR + CD8 + T cells were increased at all timepoints up to 8 months. The mean percentages of DR + CD4 + T cells were increased later and sustained longer until 12 months. Long-term (2.3 years) use of hormonal therapy did not affect the percentage of any lymphocyte population. Conclusions: Sustained long-term (up to 8 to 12 months) systemic T-cell responses were noted after combined radio-gene-hormonal therapy for prostate cancer. Prolonged use of hormonal therapy does not suppress this response. These results suggest the potential for sustained activation of cell-mediated immune responses against cancer

This meta-analysis aimed to systemically evaluate the impact of fixed-dose combination (FDC) therapy on hypertensive medication adherence compared with free-equivalent combination therapies. Articles were retrieved from MEDLINE and Embase databases using a combination of terms "fixed-dose combinations" and "adherence or compliance or persistence" and "hypertension or antihypertensive" from January 2000 to June 2017 without any language restriction. A meta-analysis was performed to parallel compare the impact of FDC vs free-equivalent combination on medicine adherence or persistence. Studies were independently reviewed by two investigators. Data from eligible studies were extracted and a meta-analysis was performed using R version 3.1.0 software. A total of nine studies scored as six of nine to eight of nine for Newcastle-Ottawa rating with 62 481 patients with hypertension were finally included for analysis. Results showed that the mean difference of medication adherence for FDC vs free-equivalent combination therapies was 14.92% (95% confidence interval, 7.38%-22.46%). Patients in FDC group were more likely to persist with their antihypertensive treatment, with a risk ratio of 1.84 (95% confidence interval, 1.00-3.39). This meta-analysis confirmed that FDC therapy, compared with free-equivalent combinations, was associated with better medication adherence or persistence for patients with hypertension. It can be reasonable for physicians, pharmacists, and policy makers to facilitate the use of FDCs for patients who need to take two or more antihypertensive drugs. ©2018 Wiley Periodicals, Inc.

    Cell transplantation and gene therapy each show promise to enhance the treatment of Parkinson's disease (PD). However, because cell transplantation and gene therapy generally require direct delivery to the central nervous system, clinical trial design involves unique scientific, ethical, and financial concerns related to the invasive nature of the procedure. Typically, such biologics have been tested in PD patients who have not received any neurosurgical intervention. Here, we suggest that PD patients undergoing deep brain stimulation (DBS) device implantation are an ideal patient population for the clinical evaluation of cell transplantation and gene therapy. Randomizing subjects to an experimental group that receives the biologic concurrently with the DBS implantation-or to a control group that receives the DBS treatment alone-has several compelling advantages. First, this study design enables the participation of patients likely to benefit from DBS, many of whom simultaneously meet the inclusion criteria of biologic studies. Second, the need for a sham neurosurgical procedure is eliminated, which may reduce ethical concerns, promote patient recruitment, and enhance the blinding of surgical trials. Third, testing the biologic by "piggybacking" onto an established, reimbursable procedure should reduce the cost of clinical trials, which may allow a greater number of biologics to reach this critical stage of research translation. Finally, this clinical trial design may lead to combinatorial treatment strategies that provide PD patients with more durable control over disabling motor symptoms. By combining neuromodulation with biologics, we may also reveal important treatment paradigms relevant to other diseases of the brain. © 2014 International Parkinson and Movement Disorder Society.

    Full Text Available The paper provides the clinical and ettological characteristics of viral encephalitis in 103 children aged 1 month to 3 years and the results of a comparative study of the efficiency of recombinant interferon-a 2b (VIFERON® as rectal suppositories incorporated into the combination therapy of the disease. The VIFERON® regimen and duration in the study were determined by the pattern of encephalitis. In the acute course of the latter, VIFERON® was given twice daily for 14 days; in its protracted or chronical course, the drug was used twice daily for 14 days, then thrice daily for 1 and 3 months, respectively. The administration of VIFERON® in viral encephalitis was established to accelerate sanogenetic processes and to reduce the time of progression and preservation of major extracerebral and cerebral symptoms and the length of sanitization of cerebrospinal fluid (CSF and viremia. The use of VIFERON® resulted in better disease outcomes, prevented deaths, decreased the rate of an autonomic state from 8 to 1,8%, increased recovery rates without defects from 22 to 51%, and reduced the rate of cystic and gliotic changes in the brain by 2,1 times. Slower CSF sanitization and longer viremia were ascertained in children with chronic and protracted viral encephalitis, which necessitated the longer administration of VIFERON®. Incorporation of recombinant interferon-a 2b into the therapy of viral encephalitis in infants ensures higher serum concentrations of interferon-a and helps keep compensatory capacities for its production, leading to the promptest recovery. The findings suggest that the incorporation of VIFERON® as rectal suppositories into the therapy of viral encephalitis is effective and safe in infants.

    The effect of adjuvant preoperative treatments with radiation and 5-fluorouracil (5-FU) on rectal carcinomas was investigated. The radiation therapy was administered in the area including the rectum and regional lymph nodes up to the level of the promontorium with 10 doses of 300 rad in three-week periods (a total dose of 3,000 rad). The suppository containing 100 mg of 5-FU was given intrarectally twice daily in the same period (a total dose of 4,000 mg of 5-FU). The surgical procedure with either abdominoperineal excision or anterior resection was performed within 14 days after the last preoperative treatment. The resected specimens were examined microscopically. The mean thickness of excised tumor-free tissue around the rectal wall having the most extended tumor growth was 6.2 mm in 16 patients receiving the treatment with radiation and 5-FU, 3.9 mm in 31 patients with 5-FU alone and 3.7 mm in 19 patients without preoperative treatments. Lymph node metastases were detected in 3 of 17 patients (19 %) with radiation and 5-FU, in 18 of 33 patients (55 %) with 5-FU alone, and in 11 of 24 patients (46 %) without preoperative treatments. The extensive degenerative pictures of cancer cells such as nuclear picnosis, and the growth of collagen fibers in carcinoma foci were observed in resected specimens with radiation and 5-FU treatments. Those findings suggest that preoperative adjuvant therapy with moderate dose of radiation and 5-FU affected significantly rectal carcinomas. There were no adverse effects. It seems likely, thus, that this combined therapy could prevent postoperative local or intrapelvic recurrence, which was the most frequent form of recurrence after curative surgery in rectal cancer.

    Purpose: To evaluate the outcome and patterns of failure for patients with nodal metastases from melanoma treated with combined-modality therapy. Methods and Materials: Between 1983 and 2003, 466 patients with nodal metastases from melanoma were managed with lymphadenectomy and radiation, with or without systemic therapy. Surgery was a therapeutic procedure for clinically apparent nodal disease in 434 patients (regionally advanced nodal disease). Adjuvant radiation was generally delivered with a hypofractionated regimen. Adjuvant systemic therapy was delivered to 154 patients. Results: With a median follow-up of 4.2 years, 252 patients relapsed and 203 patients died of progressive disease. The actuarial 5-year disease-specific, disease-free, and distant metastasis-free survival rates were 49%, 42%, and 44%, respectively. By multivariate analysis, increasing number of involved lymph nodes and primary ulceration were associated with an inferior 5-year actuarial disease-specific and distant metastasis-free survival. Also, the number of involved lymph nodes was associated with the development of brain metastases, whereas thickness was associated with lung metastases, and primary ulceration was associated with liver metastases. The actuarial 5-year regional (in-basin) control rate for all patients was 89%, and on multivariate analysis there were no patient or disease characteristics associated with inferior regional control. The risk of lymphedema was highest for those patients with groin lymph node metastases. Conclusions: Although regional nodal disease can be satisfactorily controlled with lymphadenectomy and radiation, the risk of distant metastases and melanoma death remains high. A management approach to these patients that accounts for the competing risks of distant metastases, regional failure, and long-term toxicity is needed

    Full Text Available Abstract Introduction Phantom limb sensation and phantom limb pain is a very common issue after amputations. In recent years there has been accumulating data implicating 'mirror visual feedback' or 'mirror therapy' as helpful in the treatment of phantom limb sensation and phantom limb pain. Case presentation We present the case of a 24-year-old Caucasian man, a left upper limb amputee, treated with mirror visual feedback combined with auditory feedback with improved pain relief. Conclusion This case may suggest that auditory feedback might enhance the effectiveness of mirror visual feedback and serve as a valuable addition to the complex multi-sensory processing of body perception in patients who are amputees.

    The therapy of Paget's bone disease is essentially based on the use of calcitonin and diphosphonates: both drugs, if used in large doses for long periods, have shown themselves able to provoke particular side-effects. It was, therefore, decided to study the therapeutic efficacy of combined low-dosage treatment using synthetic salmon calcitonin and sodium-etidronate on a group of patients with Paget's osteodystrophy. A clear evident diminution in plasma alkaline phosphatase, hydroxyprolinuria and whole body retention (WBR) of MDP-Tc99m was observed, demonstrating a reduction of metabolic turnover in the bone. No changes in the bone mass (BMC), evaluated by bone mineral detector, were observed at the end of treatment. With this treatment the plateau effect was shown to be appreciably less than normally occurs when either calcitonin or sodium etidronate are used alone.

    Combined antiretroviral therapy (cART) does not eradicate HIV, which persists for years and can re-establish replication if treatment is stopped. The current challenge is identifying those tissues harboring virus through cART. Here, we used HIV env-nef single genome sequencing and HIV gag droplet digital PCR (ddPCR) to survey 50 tissues from five subjects on cART with no detectable plasma viral load at death. The spleen most consistently contained multiple proviral and expressed sequences (4/5 participants). Spleen-derived HIV demonstrated two distinct phylogenetic patterns: multiple identical sequences, often from different tissues, as well as diverse viral sequences on long terminal branches. Our results suggested that ddPCR may overestimate the size of the tissue-based viral reservoir. The spleen, a lymphatic organ at the intersection of the immune and circulatory systems, may play a key role in viral persistence.

    A compact proton synchrotron with combined function lattice has been designed as a dedicated machine for cancer therapy because of its merits of easy operation and low construction cost. The lattice has a six-fold symmetry and its radius of curvature and circumference are 1.9 m and 23.9 m, respectively. For the purpose of establishing a good reference design, we have constructed a model magnet based on the three-dimensional magnetic field calculation. A magnetic field measurement has been performed with use of a three-dimensional Hall- probe. In the present paper, the results of these developments is presented together with the outline of the reference design. (3 refs) .

    Results obtained while studying 165 patients with esophageal cancer are presented. It is shown that radiation therapy and combined treatment result in the body mass loss, in the increase of katabolic processes in organism, in the negative nitrogen balance. Weaken patients, being under starvation conditions, are subjected more often to reaction changes and complications developing during the treatment. A comparison characteristics of two methods providing the organism with nutrition is given, i.e. gastrostomy and parenteral nutrition. Shown is the advantage of the adequate parenteral nutrition preventing the appearence of reaction changes and complications, improving the subjective state of patients, homeostasis indices, promoting the elimination of esophagitis phenomena, general radiation response and reaction to chemical preparations; resulting in the increase of quantity of leucocytes at leukopenia

    To improve the quality of life (QOL) of the patients with prostate cancer, we limit the radiotherapy target volume to the prostate and seminal vesicles while using endocrine therapy towards the disease outside the target volume. Radiotherapy technique was rotation conformation technique with computer-controlled multileaf collimators to the total doses of up to 66-70 Gy. Among 145 evaluable cases with the median age of 74, overall and cause-specific 5-year survival rates were 59.3% and 84.1%, respectively, and the relative survival rate of the Stage A-C cases was 100%. The two thirds (33/50) of the deaths were not of prostate cancer. The rate of severe complication was 1.4%. As for QOL, the rate of impotence was 90%, however, the patients' overall satisfaction towards the treatment was 90%. From this analysis, this combined treatment seems beneficial in the treatment of prostate cancer. (author)

    2016-01-01

    LDLc levels are associated with increase of cardiovascular risk, and statins are currently used for their control. Nevertheless, a despite of LDLc levels at goal, a residual risk is persistent, commonly associated with persistent lipids modifications (high triglycerides and low HDLc). So, it is necessary to evaluate triglycerides and HDL to assessment cardiovascular risk. Clinical data are consistent with efficacy and safety of combination therapy with statin and other lipid lowering drugs, for instance fenofibrate. Patients with hipertriglyceridemia and low HDLc are the group with most potential improve. In that patients with atherogenic dyslipidemia, the target for therapeutic objectives related with non-HDL-cholesterol is a priority, because non-HDL-cholesterol is considered as a more accuracy measure to assessment cardiovascular risk.

    Benign cicatricial airway stenosis (BCAS) is a life-threatening disease. While there are numerous therapies, all have their defects, and stenosis can easily become recurrent. This study aimed to investigate the efficacy and complications of nonstent combination interventional therapy (NSCIT) when used for the treatment of BCAS of different causes and types. This study enrolled a cohort of patients with BCAS resulting from tuberculosis, intubation, tracheotomy, and other origins. The patients were assigned to three groups determined by their type of stenosis: Web-like stenosis, granulation stenosis, and complex stenosis, and all patients received NSCIT. The efficacy and complications of treatment in each group of patients were observed. The Chi-square test, one-factor analysis of variance (ANOVA), and the paired t -test were used to analyze different parameters. The 10 patients with web-like stenosis and six patients with granulation stenosis exhibited durable remission rates of 100%. Among 41 patients with complex stenosis, 36 cases (88%) experienced remission and 29 cases (71%) experienced durable remission. When five patients with airway collapse were eliminated from the analysis, the overall remission rate was 97%. The average treatment durations for patients with web-like stenosis, granulation stenosis, and complex stenosis were 101, 21, and 110 days, respectively, and the average number of treatments was five, two, and five, respectively. NSCIT demonstrated good therapeutic efficacy and was associated with few complications. However, this approach was ineffective for treating patients with airway collapse or malacia.

    Full Text Available Magnetic nanoparticle (MNP-mediated hyperthermia (MH coupled with radiation therapy (RT is a novel approach that has the potential to overcome various practical difficulties encountered in cancer treatment. In this work, we present recommendations for the in vitro and in vivo testing and application of the two treatment techniques. These recommendations were developed by the members of Working Group 3 of COST Action TD 1402: Multifunctional Nanoparticles for Magnetic Hyperthermia and Indirect Radiation Therapy (“Radiomag”. The purpose of the recommendations is not to provide definitive answers and directions but, rather, to outline those tests and considerations that a researcher must address in order to perform in vitro and in vivo studies. The recommendations are divided into 5 parts: (a in vitro evaluation of MNPs; (b in vitro evaluation of MNP-cell interactions; (c in vivo evaluation of the MNPs; (d MH combined with RT; and (e pharmacokinetic studies of MNPs. Synthesis and characterization of the MNPs, as well as RT protocols, are beyond the scope of this work.

    Full Text Available The current recommendations for the pharmacotherapy of osteoarthritis (OA primarily focus on analgesics and main concern is with the use of paracetamol and nonsteroidal anti-inflammatory drugs (NSAIDs. Intraarticular injections of first of all hyaluronic acid (HA preparations that have proven to be effective in clinical practice are a promising treatment for OA. By taking into account the favorable safety profile of HA preparations, it may be suggested that these injections may be an acceptable alternative to NSAIDs or successfully used in combination with the latter. There have been recently the recommendations for the administration of HA preparations in OA treatment, which characterize the current practice of HA use for OA and had been prepared by a group of experts from 5 European countries. The experts consider that there is today rather solid evidence to demonstrate the efficacy of HA in mild and moderately severe knee OA; moreover, its effect is clinically significant in such patients. In the authors’ view, topical HA therapy should be a compulsory component of treatment for knee OA, since the alternative possibilities of therapy for this disease are limited. Although the optimal effect of HA is observed when it is applied in the early stage of OA, this treatment may be also useful in its late stage. HA should be regarded as an adjunct method that must be applied if surgery cannot be performed in these patients.

    Introduction The multifactorial etiology of septic cardiomyopathy is not fully elucidated. Recently, high catecholamine levels have been suggested to contribute to impaired myocardial function. Methods This retrospective analysis summarizes our preliminary clinical experience with the combined use of milrinone and enteral metoprolol therapy in 40 patients with septic shock and cardiac depression. Patients with other causes of shock or cardiac failure, patients with beta-blocker therapy initiated more than 48 hours after shock onset, and patients with pre-existent decompensated congestive heart failure were excluded. In all study patients, beta blockers were initiated only after stabilization of cardiovascular function (17.7 ± 15.5 hours after shock onset or intensive care unit admission) in order to decrease the heart rate to less than 95 beats per minute (bpm). Hemodynamic data and laboratory parameters were extracted from medical charts and documented before and 6, 12, 24, 48, 72, and 96 hours after the first metoprolol dosage. Adverse cardiovascular events were documented. Descriptive statistical methods and a linear mixed-effects model were used for statistical analysis. Results Heart rate control (65 to 95 bpm) was achieved in 97.5% of patients (n = 39) within 12.2 ± 12.4 hours. Heart rate, central venous pressure, and norepinephrine, arginine vasopressin, and milrinone dosages decreased (all P milrinone dosages were increased in nine (22.5%) and six (15%) patients, respectively. pH increased (P < 0.001) whereas arterial lactate (P < 0.001), serum C-reactive protein (P = 0.001), and creatinine (P = 0.02) levels decreased during the observation period. Twenty-eight-day mortality was 33%. Conclusion Low doses of enteral metoprolol in combination with phosphodiesterase inhibitors are feasible in patients with septic shock and cardiac depression but no overt heart failure. Future prospective controlled trials on the use of beta blockers for septic cardiomyopathy

The instigation enrolled 7 patients after ischemic stroke (7 years ago with the signs of upper limb spasticity. All the patients received combination treatment that involved daily kinesiotherapy sessions and electrical stimulation of the paralyzed limbs. Relatox® was once injected into the forearm muscles of the paralyzed arm 6 months or later after stroke. Muscles were chosen according to clinical and electromyographic findings. The patients' status was assessed before, 2 weeks and 3 months after injection.There were changes in muscle tone, motor abilities of the hand, in the degree of self-service, the presence of subjective sensations, and the degree of local and systemic reactions. The efficiency of therapy was evaluated clinically (Ashworth scale, Frenchay test, Barthel index and on the basis of an analysis of video monitoring a patient's status and of the consideration of care-givers' views.Before included in the study, all the patients were treated with different types of botulinum neurotoxin type A made by other manufacturers.Results. The clinical efficiency of local intramuscular injection of the botulinum toxin type Relatox® in combination with kinesiotherapy and electrical stimulation after 14 days and 3 months after injection was noted in all cases.The good tolerability, efficacy, and long-term of action of relatox, which were comparable to those of other botulinum neurotoxin type A products, were noted during a 3-month follow-up. Neither side effects no adverse events were identified.Conclusion. Accumulation of data on the doses and effects of drugs for the local therapy of post-stroke spasticity, which have been obtained by different clinical centers, and the possibility of choosing a medication will be able to improve treatment in such

    Full Text Available Objectives: This study aimed at describing the pattern of outpatient antimalarial drug prescribing in a secondary and a tertiary hospital, and to assess adherence to the National Antimalarial Treatment Guideline (ATG. Methods: An audit of antimalarial prescription files from the two health facilities for a period of six months in 2008 was conducted. Semi structured questionnaires were used to collect information from the doctors and pharmacists on their awareness and knowledge of the National Antimalarial Treatment Guideline. Results: Artemisinin-based combination therapies (ACTs were the most prescribed antimalarials. Overall, 81.4% of the total prescriptions contained ACTs, out of which 56.8% were artemether-lumefantrine. However, adherence to the drugs indicated by national guideline within the DU90% was 38.5% for the tertiary and 66.7 % for the secondary hospital. The standard practice of prescribing with generic name was still not adhered to as evidenced in the understudied hospitals. The percentage of health care providers that were aware of the ATG was 88.2% for doctors and 85.1% for pharmacists. However, 13.3% and 52.2% of doctors and pharmacists respectively could not properly list the drugs specified in the guideline. Amodiaquine was the most commonly preferred option for managing children aged 0 – 3 months with malaria infection against the indicated oral quinine.Conclusion: This study showed an increased use of artemisinin-based combination therapy for the treatment of uncomplicated malaria compared previous reports in Nigeria. This study also highlights the need for periodic in-service quality assurance among health professionals with monitoring of adherence to and assessment of knowledge of clinical guidelines to ensure the practice of evidence based medicine.

    Hepatitis C virus (HCV) presents several regions involved potentially in evading antiviral treatment and host immune system. Two regions, known as PKR-BD and V3 domains, have been proposed to be involved in resistance to interferon. Additionally, hypervariable regions in the envelope E2 glycoprotein are also good candidates to participate in evasion from the immune system. In this study, we have used a cohort of 22 non-responder patients to combined therapy (interferon alpha-2a plus ribavirin) for which samples obtained just before initiation of therapy and after 6 or/and 12 months of treatment were available. A range of 25-100 clones per patient, genome region and time sample were obtained. The predominant amino acid sequences for each time sample and patient were determined. Next, the sequences of the PKR-BD and V3 domains and the hypervariable regions from different time samples were compared for each patient. The highest levels of variability were detected at the three hypervariable regions of the E2 protein and, to a lower extent, at the V3 domain of the NS5A protein. However, no clear patterns of adaptation to the host immune system or to antiviral treatment were detected. In summary, although high levels of variability are correlated to viral adaptive response, antiviral treatment does not seem to promote convergent adaptive changes. Consequently, other regions must be involved in evasion strategies likely based on a combination of multiple mechanisms, in which pools of changes along the HCV genome could confer viruses the ability to overcome strong selective pressures.

    2016-03-01

    Full Text Available Cognitive behavioural psychotherapy is, just like other psychotherapeutic systems, of an eclectic nature. Should a therapist be successful across a wide range of issues, he/she needs to be adaptable, flexible and eclectic in terms of the techniques applied. Eclectically oriented therapists use a wide range of interventions; however, they adhere to individual theoretical structures. The aim of the paper is to point out the application of a combination of artistic activities within the system of the Cognitive behavioural therapy. For this purpose the paper presents a qualitative analysis of two case studies. We formulated the following research questions. Can the methods of combining the cognitive behavioural therapy and art accelerate the course of therapy? Can the methods of combining the cognitive behavioural therapy and art be perceived by the client as effective? The phenomenon investigated in the case study is a functional analysis of a client’s case and subsequent application of therapeutic and educational techniques of the Cognitive behavioural therapy and art. In both case studies it was demonstrated that the involvement of therapeutic elements accelerated the course of therapy. The clients in the research sample assessed the therapy as beneficial.

    Early reports cautioned against the combination of lithium and electroconvulsive therapy (ECT), citing risk of excessive cognitive disturbance, prolonged apnea, and spontaneous seizures. However, recent case series with larger numbers of patients indicate that the combination may be used safely and with optimal efficacy in certain clinical circumstances. In this report, we describe 12 patients in whom the combination of lithium and ECT was deemed safe. We also provide a comprehensive review of published literature and provide detailed recommendations for clinical practice.

    Multi-targeted agents represent the next generation of targeted therapies for solid tumors, and patients with acquired resistance to EGFR-tyrosine kinase inhibitors (TKIs) may also benefit from their combination with TKI therapy. Third-generation targeted drugs, such as osimertinib, are very expensive, thus a more economical solution is required. The aim of this study was to explore the use of apatinib combined with icotinib therapy for primary acquired resistance to icotinib in three patients with advanced pulmonary adenocarcinoma with EGFR mutations. We achieved favorable oncologic outcomes in all three patients, with progression-free survival of four to six months. Unfortunately, the patients ultimately had to cease combination therapy because of intolerable adverse effects of hand and foot syndrome and oral ulcers. Combination therapy of apatinib with icotinib for primary acquired resistance to icotinib may be an option for patients with advanced pulmonary adenocarcinoma with EGFR mutations, but physicians must also be aware of the side effects caused by such therapy. © 2018 The Authors.

  9. Upfront triple combination therapy-induced pulmonary edema in a case of pulmonary arterial hypertension associated with Sjogren's syndrome

    Directory of Open Access Journals (Sweden)

    Kimikazu Takeuchi

    Full Text Available Clinical efficacy of combination therapy using vasodilators for pulmonary arterial hypertension (PAH is well established. However, information on its safety are limited. We experienced a case of primary Sjogren's syndrome associated with PAH where the patient developed pulmonary edema immediately after the introduction of upfront triple combination therapy. Although the combination therapy successfully stabilized her pre-shock state, multiple ground glass opacities (GGO emerged. We aborted the dose escalation of epoprostenol and initiated continuous furosemide infusion and noninvasive positive pressure ventilation (NPPV, but this did not prevent an exacerbation of pulmonary edema. Chest computed tomography showing diffuse alveolar infiltrates without inter-lobular septal thickening suggests the pulmonary edema was unlikely due to cardiogenic pulmonary edema and pulmonary venous occlusive disease. Acute respiratory distress syndrome was also denied from no remarkable inflammatory sign and negative results of drug-induced lymphocyte stimulation tests (DLST. We diagnosed the etiological mechanism as pulmonary vasodilator-induced trans-capillary fluid leakage. Following steroid pulse therapy dramatically improved GGO. We realized that overmuch dose escalation of epoprostenol on the top of dual upfront combination poses the risk of pulmonary edema. Steroid pulse therapy might be effective in cases of vasodilator-induced pulmonary edema in Sjogren's syndrome associated with PAH.

    Purpose: This phase 2 study evaluated the efficacy of radiation therapy (RT) with concurrent and sequential sorafenib therapy in patients with unresectable hepatocellular carcinoma (HCC). Methods and Materials: Forty patients with unresectable HCC unfit for transarterial chemoembolization were treated with RT with concurrent and sequential sorafenib. Sorafenib was administered from the commencement of RT at a dose of 400 mg twice daily and continued to clinical or radiologic progression, unacceptable adverse events, or death. All patients had underlying Child-Pugh A cirrhosis. The maximal tumor diameter ranged from 3.0 cm to 15.5 cm. Coexisting portal vein thrombosis was found in 24 patients and was irradiated simultaneously. The cumulative RT dose ranged from 40 Gy to 60 Gy (median, 50 Gy). Image studies were done 1 month after RT and then every 3 months thereafter. Results: Thirty-three (83%) completed the allocated RT. During RT, the incidence of hand-foot skin reactions ≥ grade 2 and diarrhea were 37.5% and 25%, respectively, and 35% of patients had hepatic toxicities grade ≥2. Twenty-two (55.0%) patients achieved complete or partial remission at the initial assessment, and 18 (45%) had stable or progressive disease. The 2-year overall survival and infield progression-free survival (IFPS) were 32% and 39%, respectively. A Cancer of the Liver Italian Program (CLIP) score ≥2 was associated with an inferior outcome in overall survival. Six patients (15%) developed treatment-related hepatic toxicity grade ≥3 during the sequential phase, and 3 of them were fatal. Conclusions: When RT and sorafenib therapy were combined in patients with unresectable HCC, the initial complete or partial response rate was 55% with a 2-year IFPS of 39%. A CLIP score ≥2 was associated with an inferior outcome in overall survival. Hepatic toxicities are a major determinant of the safety; the combination should be used with caution and needs further investigation.

    AIM: To elucidate the frequency and risk factors for retinopathy in patients with chronic hepatitis C who are treated by interferon-ribavirin combination therapy.METHODS: We prospectively analyzed 73 patients with histologically confirmed chronic hepatitis C, who underwent combination therapy for 24 wk. Optic fundi were examined before, and 2, 4, 12 and 24 wk after the start of combination therapy.RESULTS: Fourteen patients (19%) developed retinopathy, which was initially diagnosed by the appearance of a cotton wool spot in 12 patients. Retinal hemorrhage was observed in 5 patients. No patient complained of visual disturbance. Retinopathy disappeared in 9 patients (64%)despite the continuation of combination therapy. However, retinopathy persisted in 5 patients with retinal hemorrhage. A comparison of the clinical background between the groups with and without retinopathy showed no significant differences in age, gender, viral genotype, RNA level, white blood cell count, platelet count, prothrombin time, complications by diabetes mellitus or hypertension,or pretreatment arteriosclerotic changes in the optic fundj. However, multiple logistic regression analysis revealed that complication by hypertension was observed with a high frequency in the group with retinopathy (P=0.004,OR=245.918, 95% CI=5.6-10786.2).CONCLUSION: Retinopathy associated with combination therapy of interferon α-2b and ribavirin tends to develop in patients with hypertension.

    Full Text Available This study aimed to describe the epidemiology and risk factors of cholelithiasis and nephrolithiasis among HIV-positive patients in the era of combination antiretroviral therapy.We retrospectively reviewed the medical records of HIV-positive patients who underwent routine abdominal sonography for chronic viral hepatitis, fatty liver, or elevated aminotransferases between January 2004 and January 2015. Therapeutic drug monitoring of plasma concentrations of atazanavir was performed and genetic polymorphisms, including UDP-glucuronosyltransferase (UGT 1A1*28 and multidrug resistance gene 1 (MDR1 G2677T/A, were determined in a subgroup of patients who received ritonavir-boosted or unboosted atazanavir-containing combination antiretroviral therapy. Information on demographics, clinical characteristics, and laboratory testing were collected and analyzed.During the 11-year study period, 910 patients who underwent routine abdominal sonography were included for analysis. The patients were mostly male (96.9% with a mean age of 42.2 years and mean body-mass index of 22.9 kg/m2 and 85.8% being on antiretroviral therapy. The anchor antiretroviral agents included non-nucleoside reverse-transcriptase inhibitors (49.3%, unboosted atazanavir (34.4%, ritonavir-boosted lopinavir (20.4%, and ritonavir-boosted atazanavir (5.5%. The overall prevalence of cholelithiasis and nephrolithiasis was 12.5% and 8.2%, respectively. Among 680 antiretroviral-experienced patients with both baseline and follow-up sonography, the crude incidence of cholelithiasis and nephrolithiasis was 4.3% and 3.7%, respectively. In multivariate analysis, the independent factors associated with incident cholelithiasis were exposure to ritonavir-boosted atazanavir for >2 years (adjusted odds ratio [AOR], 6.29; 95% confidence interval [CI], 1.12-35.16 and older age (AOR, 1.04; 95% CI, 1.00-1.09.

    The multidrug resistance profiles of Klebsiella pneumoniae carbapenemase (KPC) producers have led to increased clinical polymyxin use. Combination therapy with polymyxins may improve treatment outcomes, but it is uncertain which combinations are most effective. Clinical successes with intravenous minocycline-based combination treatments have been reported for infections caused by carbapenemase-producing bacteria. The objective of this study was to evaluate the in vitro activity of polymyxin B and minocycline combination therapy against six KPC-2-producing K. pneumoniae isolates (minocycline MIC range, 2 to 32 mg/liter). Polymyxin B monotherapy (0.5, 1, 2, 4, and 16 mg/liter) resulted in a rapid reduction of up to 6 log in bactericidal activity followed by regrowth by 24 h. Minocycline monotherapy (1, 2, 4, 8, and 16 mg/liter) showed no reduction of activity of >1.34 log against all isolates, although concentrations of 8 and 16 mg/liter prolonged the time to regrowth. When the therapies were used in combination, rapid bactericidal activity was followed by slower regrowth, with synergy (60 of 120 combinations at 24 h, 19 of 120 combinations at 48 h) and additivity (43 of 120 combinations at 24 h, 44 of 120 combinations at 48 h) against all isolates. The extent of killing was greatest against the more susceptible polymyxin B isolates (MICs of ≤0.5 mg/liter) regardless of the minocycline MIC. The pharmacodynamic activity of combined polymyxin B-minocycline therapy against KPC-producing K. pneumoniae is dependent on polymyxin B susceptibility. Further in vitro and animal studies must be performed to fully evaluate the efficacy of this drug combination. Copyright © 2017 American Society for Microbiology.

Effleurage massage and consuming green coconut water are considered able to reduce menstrual pain. However, little is known about the effect of the combination between the two interventions. Objective: To compare the effectiveness of effleurage massage and in combination with green coconut water on pain, anxiety, and ß-endorphin level in teenage girls with menstrual pain (dysmenorrhea. Design: A quasy experiment with pretest-posttest approach design with control group. There were 36 samples recruited in this study by purposive sampling, which were divided into a massage therapy group, the combination therapy group, and a control group. Menstrual pain was measured using Numeric Rating Scale, while anxiety was measured using Zung Self rating Anxiety Scale (ZSAS, and endorphin level using ELISA (Enzyme-Linked Immunosorbent Assay. One way anova test and repeated anova were performed as a bivariate analysis. Mancova and post hoc anova were used for multivariate analysis. Result: The combination of massage and green coconut water was more effective in reducing pain (p 0.013 and anxiety levels (p 0.000, and in increasing β-endorphin (p 0.029 with significant value of <0.05 compared to the massage therapy alone. Conclusion: The combination of effleurage massage and green coconut water had significant effect in decreasing anxiety and pain levels, and increasing β-endorphin levels in teenage girls with painful periods (dysmenorrhea; and more effective than performing effleurage massage only. It is suggested that this combination therapy could be used as an alternative therapy for women with dysmenrrohea.

    We have studied efficiency of a complex therapy with metformin and ramipril combination (1000 mg and 5 mg per day) respectively in patients with metabolic syndrome (MS). The group of patients with MS which answered the basic criteria IDF (2005) was determined. Carbohydrate and Lipidic metabolism were studied. Patients were characterized with raised weight index (WI), arterial hypertension, increased concentration of triglycerides in blood serum, of glucose, of HbAlc level and S-peptide, and also high level of endotelin (1-38) and CD32+CD40+circulating particles of endothelium. Three months treatment lead to decrease in WI, arterial pressure, triglycerides concentration, HbAlc, glucose, except CD32+CD40+. Six months treatment lead to more expressed positive dynamics. Thus, metformin and ramipril combination in patients with MS leads to decrease in insulin resistancy, carbohydrate and lipid metabolism normalization, to restoration of endothelium functions that is possible to consider as prophylaxis of the development of type 2 diabetes melitus and its cardiovascular complications.

    Full Text Available Background. For large basal cell carcinomas (BCCs of the head and neck, definitive surgery often requires extensive resection and reconstruction that may result in prolonged recovery and limited cosmesis. Vismodegib, a small-molecule inhibitor of the hedgehog pathway, is approved for advanced and metastatic BCCs. We present a case of advanced BCC treated with combination of vismodegib, radiotherapy, and local excision resulting in excellent response and cosmesis. Case Presentation. A 64-year-old gentleman presented with a 5-year history of a 7 cm enlarging right cheek mass, with extensive vascularization, central ulceration, and skin, soft tissue, and buccal mucosa involvement. Biopsy revealed BCC, nodular type. Up-front surgical option involved a large resection and reconstruction. After multidisciplinary discussion, we recommended and he opted for combined modality of vismodegib, radiotherapy, and local excision. The patient tolerated vismodegib well and his right cheek lesion decreased significantly in size. He was then treated with radiotherapy followed by local excision that revealed only focal residual BCC. Currently, he is without evidence of disease and has excellent cosmesis. Conclusions. We report a case of locally advanced BCC treated with trimodality therapy with vismodegib, radiotherapy, and local excision, resulting in excellent outcome and facial cosmesis, without requiring extensive resection or reconstructive surgery.

    Diabetic kidney disease (DKD) is the most common cause of end stage renal disease. The comprehensive management of DKD depends on combined target-therapies for hyperglycemia, hypertension, albuminuria, and hyperlipaemia, etc. Sodium-glucose co-transporter 2 (SGLT2) inhibitors, the most recently developed oral hypoglycemic agents acted on renal proximal tubules, suppress glucose reabsorption and increase urinary glucose excretion. Besides improvements in glycemic control, they presented excellent performances in direct renoprotective effects and the cardiovascular (CV) safety by decreasing albuminuria and the independent CV risk factors such as body weight and blood pressure, etc. Simultaneous use of SGLT-2 inhibitors and renin-angiotensin-aldosterone system (RAAS) blockers are novel strategies to slow the progression of DKD via reducing inflammatory and fibrotic markers induced by hyperglycaemia more than either drug alone. The available population and animal based studies have described SGLT2 inhibitors plus RAAS blockers. The present review was to systematically review the potential renal benefits of SGLT2 inhibitors combined with dipeptidyl peptidase-4 inhibitors, glucagon-like peptide-1 receptor agonists, mineralocorticoid receptor antagonists, and especially the angiotensin-converting enzyme inhibitors/angiotensin receptor blockers.

    Combination effects of photodynamic therapy (PDT) with meso-tetra (di-adjacent- sulfonatophenyl) porphine (TPPS2a) and the microtubule (MT) inhibitor, vincristine (VCR), were studied in the CaD2 mouse tumor model in mice. A synergistic effect was found when VCR, at an almost nontoxic dose (1 mg/kg), was injected i.p. into the mice 6 hr before PDT. The data on mitotic index show a 4 - 5 fold accumulation of the cells in mitosis 6 hr after injection of VCR into the mice. Cell cycle and ploidy distributions in tumor tissues were determined by means of image analysis with measurement of integrated optical density after Feulgen reaction on monolayers. Ploidy distribution of the tumors was not significantly changed 6 and 12 hr after administration of VCR only, while an increasing aneuploidy was observed 24 and 48 hr after VCR treatment. No prominent changes of the cell cycle and ploidy distributions were found in the tumor tissues after PDT or PDT combined with VCR.

    Full Text Available Objective. This is a retrospective interventional case series describing the results of 5 eyes from 5 patients with symptomatic peripapillary choroidal neovascularization (CNVM receiving initial bevacizumab treatment followed by thermal laser and bevacizumab combination therapy. Methods. Patients received intravitreal bevacizumab injections until the lesions were well-defined. Thermal laser ablation was then administered and followed by an additional bevacizumab injection after one week. Visual outcomes, OCT changes, and rates of recurrence were recorded and analyzed. Results. Median visual outcomes improved from 20/50 to 20/30 (p=0.0232. Median central macular thickness decreased from 347 μm to 152 μm (p=0.0253. The mean visual improvement was 3 lines. An average of 3.8 bevacizumab injections per patient were given overall. Patients were followed for an average of 24 months, during which all eyes were absent for recurrence. Conclusion. Symptomatic peripapillary CNVM may be successfully managed with bevacizumab followed by a combination of thermal laser and bevacizumab without the need for frequent retreatment. The area requiring treatment may be better defined using bevacizumab, limiting the ablation of the healthy retina and improving treatment margins. With this treatment regimen, the patients experience improved visual outcomes and have a low rate of recurrence.

  6. Emerging combination therapies for metastatic colorectal cancer – impact of trifluridine/tipiracil

    2017-01-01

    Patients with metastatic colorectal cancer (mCRC) are surviving longer now than ever before, but mortality rates are still high and more effective therapies are clearly needed. For patients with disease that is refractory to fluoropyrimidines, oxaliplatin, irinotecan, and biologic agents targeting the vascular endothelial growth factor and epidermal growth factor receptor pathways, novel treatment options trifluridine/tipiracil (TAS-102) and regorafenib can be effective disease stabilizers. However, objective clinical responses are rare and toxicities are manageable but common. In order to tackle poor clinical responses to TAS-102, there is an ongoing effort to effectively combine this drug with other agents, particularly those targeting angiogenesis. Certain subpopulations appear to benefit more than others from TAS-102; those that benefit often have underlying genetic defects in DNA repair pathways and/or develop neutropenia. In this review, we focus on the role of TAS-102 in the treatment of mCRC, including its use in combination with other agents, potential predictive biomarkers of response to TAS-102, and possible future directions.

For patients with disease that is refractory to fluoropyrimidines, oxaliplatin, irinotecan, and biologic agents targeting the vascular endothelial growth factor and epidermal growth factor receptor pathways, novel treatment options trifluridine/tipiracil (TAS-102 and regorafenib can be effective disease stabilizers. However, objective clinical responses are rare and toxicities are manageable but common. In order to tackle poor clinical responses to TAS-102, there is an ongoing effort to effectively combine this drug with other agents, particularly those targeting angiogenesis. Certain subpopulations appear to benefit more than others from TAS-102; those that benefit often have underlying genetic defects in DNA repair pathways and/or develop neutropenia. In this review, we focus on the role of TAS-102 in the treatment of mCRC, including its use in combination with other agents, potential predictive biomarkers of response to TAS-102, and possible future directions.

    Colon 26, a transplantable strain of colon cancer, was implanted in BALB/C mice, and the effect of combination therapy with irradiation and ACNU on the mice was studied. Regional irradiation with 9 MeV electron beams was administered once without anesthetization, and ACNU was injected intraperitoneally. The 102 mice used as subjects were divided into 6 groups: nontreated group, 3 Gy irradiation group, 9 Gy irradiation group, 20 mg/kg ACNU group, 40 mg/kg ACNU group, and 3 Gy irradiation + 20 mg/kg ACNU group. Antitumor effects were evaluated based on survival time and inhibition of tumor volume growth, which were calculated from mean days of survival, Kaplan-Meier survival rate curves, and tumor volume growth curves, and the results were compared among these 6 groups. In addition, pathological and cytological studies were performed. As a result, antitumor effect was found to be significantly remarkable in the group receiving the combination of irradiation and ACNU compared to any other group given either irradiation or ACNU alone, suggesting that the antitumor effect of irradiation was potentiated by ACNU.

    The opioid antagonist naltrexone, combined with cognitive behavioural therapy (CBT), has proven efficacious for patients with alcohol dependence, but studies examining how this treatment works in a naturalistic treatment setting are lacking. This study examined predictors of the outcome of targeted naltrexone and CBT in a real-life outpatient setting. Participants were 315 patients who attended a treatment program providing CBT combined with the targeted use of naltrexone. Mixture models for estimating developmental trajectories were used to examine change in patients' alcohol consumption and symptoms of alcohol craving from treatment entry until the end of the treatment (20 weeks) or dropout. Predictors of treatment outcome were examined with analyses of multinomial logistic regression. Minimal exclusion criteria were applied to enhance the generalizability of the findings. Regular drinking pattern, having no history of previous treatments, and high-risk alcohol consumption level before the treatment were associated with less change in alcohol use during the treatment. The patients with low-risk alcohol consumption level before the treatment had the most rapid reduction in alcohol craving. Patients who drank more alcohol during the treatment had lower adherence with naltrexone. Medication non-adherence is a major barrier to naltrexone's effectiveness in a real-life treatment setting. Patients with more severe alcohol problems may need more intensive treatment for achieving better treatment outcome in real-word treatment settings.

Our in vitro data showed that the cytotoxicity of PDT in combination with EP increases fourfold on the average. Based on the results we suggest...... tumor therapy (PDT)--the cancer treatment method based on the use of photosensitizers that localize selectively in malignant tumors and become cytotoxic when exposed to light, and EP, with the aim to enhance the delivery of photosensitizers into the tumor and therefore to increase the efficacy of PDT....... Thus, the aim of study was to evaluate the cytotoxic effect of PDT in combination with EP. A Chinese hamster lung fibroblast cell line (DC-3F) was used. The cells were affected by photosensitizers chlorin e(6) (C e(6)) at the dose of 10 mug/ml and aluminium phthalocyanine tetrasulfonate (AlPcS4...

    Purpose: Nasopharyngeal carcinoma (NPC) is a malignant disease of the head/neck region, with a 5-year survival level of approximately 65%. To explore gene therapy as a novel approach which might improve outcome, we have shown previously that introduction of human recombinant wild-type p53 mediated by the adenoviral vector (Ad5CMV-p53) was cytotoxic in two human nasopharyngeal carcinoma (NPC) cell lines (CNE-1 and CNE-2Z). The current work was designed to determine whether this strategy, combined with ionizing radiation (XRT), was more effective than either treatment alone. Methods and Materials: CNE-1, CNE-2Z, and a normal human nasopharyngeal fibroblast strain, KS1, were infected with 2- and 6-plaque-forming units (pfu)/cell of Ad5CMV-p53, respectively. These doses were iso-effective for β-galactosidase activity in the CNE-1 and CNE-2Z cells. XRT was administered 24 h post-infection, and Western blot analyses were conducted for p53, p21 WAF1/CIP1 , bax, and bcl-2 2 days after XRT. Cell survival was assessed using a clonogenic assay. Presence of DNA ladders reflecting apoptosis was detected using DNA agarose gel electrophoresis, and cell cycle was analyzed using flow cytometry. Results: The combination of Ad5CMV-p53 plus XRT (2, 4, and 6 Gy) resulted in an approximately 1-log greater level of cytotoxicity compared to that observed with XRT alone for both NPC cell lines. The two modalities appear to be interacting in a synergistic manner in cancer cells, but not in KS1 fibroblasts. XRT alone stimulated minimal p53 expression in control cells; Ad5CMV-p53 alone induced significant recombinant p53 expression, which was not further enhanced by the addition of XRT. Similar observations were made for p21 WAF1/CIP1 expression. No changes were observed for bax or bcl-2 expression with any of these treatments. Apoptosis was induced following 4 Gy of XRT alone, but was observed after only 2 Gy when combined with Ad5CMV-p53. Cell cycle analysis indicated that Ad5CMV-p53

    DMG, a degraded D-manno-D-glucan with a host-mediated antitumor activity did not significantly enhance nor inhibit the development of suppressor cells for either the antibody-forming response or the delayed hypersensitivity reaction to sheep red blood cells. Cyclophosphamide (CY), which inhibited the generation of suppressor cells, was combined with DMG in treatment of murine syngeneic tumors to obtain a higher antitumor activity. The antitumor activity of the combination against MH134 hepatoma was synergistically higher than that of either component alone. A marked antitumor effect of the combination treatment against MM46 mammary carcinoma was also shown. High levels of antitumor delayed hypersensitivity reactions were observed with this combination therapy. The possible roles of DMG and CY in this combination therapy are discussed.

    Chest tube removal is an extremely painful procedure and patients may not respond well to palliative therapies. This study aimed to examine the effect of cold and music therapy individually, as well as a combination of these interventions on reducing pain following chest tube removal. A factorial randomized-controlled clinical trial was performed on 180 patients who underwent cardiac surgery. Patients were randomized into four groups of 45. Group A used ice packs for 20 minutes prior to chest tube removal. Group B was assigned to listen to music for a total length of 30 minutes which started 15 minutes prior to chest tube removal. Group C received a combination of both interventions; and Group D received no interventions. Pain intensity was measured in each group every 15 minutes for a total of 3 readings. Analysis of variance, Tukey and Bonferroni post hoc tests, as well as repeated measures ANOVA were employed for data analysis. Cold therapy and combined method intervention effectively reduced the pain caused by chest tube removal (P < 0.001). Additionally, there were no statistically significant difference in pain intensity scores between groups at 15 minutes following chest tube removal (P = 0.07). Cold and music therapy can be used by nursing staff in clinical practice as a combined approach to provide effective pain control following chest tube removal. Copyright © 2018 Elsevier Ltd.

    Full Text Available The multikinase inhibitor regorafenib (BAY 73-4506 exerts both anti-angiogenic and anti-tumorigenic activity in adult solid malignancies mainly advanced colorectal cancer and gastrointestinal stromal tumors. We intended to explore preclinically the potential of regorafenib against solid pediatric malignancies alone and in combination with anticancer agents to guide the pediatric development plan. In vitro effects on cell proliferation were screened against 33 solid tumor cell lines of the Innovative Therapies for Children with Cancer (ITCC panel covering five pediatric solid malignancies. Regorafenib inhibited cell proliferation with a mean half maximal growth inhibition of 12.5 μmol/L (range 0.7 μmol/L to 28 μmol/L. In vivo, regorafenib was evaluated alone at 10 or 30 mg/kg/d or in combination with radiation, irinotecan or the mitogen-activated protein kinase kinase (MEK inhibitor refametinib against various tumor types, including patient-derived brain tumor models with an amplified platelet-derived growth factor receptor A (PDGFRA gene. Regorafenib alone significantly inhibited tumor growth in all xenografts derived from nervous system and connective tissue tumors. Enhanced effects were observed when regorafenib was combined with irradiation and irinotecan against PDGFRA amplified IGRG93 glioma and IGRM57 medulloblastoma respectively, resulting in 100% tumor regressions. Antitumor activity was associated with decreased tumor vascularization, inhibition of PDGFR signaling, and induction of apoptotic cell death. Our work demonstrates that regorafenib exhibits significant antitumor activity in a wide spectrum of preclinical pediatric models through inhibition of angiogenesis and induction of apoptosis. Furthermore, radio- and chemosensitizing effects were observed with DNA damaging agents in PDGFR amplified tumors.

    Cancer is an important cause of morbidity and mortality in individuals infected with human immunodeficiency virus (HIV), but patterns of cancer incidence after combination antiretroviral therapy (ART) initiation remain poorly characterized. We evaluated the incidence and timing of cancer diagnoses among patients initiating ART between 1996 and 2011 in a collaboration of 8 US clinical HIV cohorts. Poisson regression was used to estimate incidence rates. Cox regression was used to identify demographic and clinical characteristics associated with cancer incidence after ART initiation. At initiation of first combination ART among 11 485 patients, median year was 2004 (interquartile range [IQR], 2000-2007) and median CD4 count was 202 cells/mm(3) (IQR, 61-338). Incidence rates for Kaposi sarcoma (KS) and lymphomas were highest in the first 6 months after ART initiation (P cancers combined increased from 416 to 615 cases per 100 000 person-years from 1 to 10 years after ART initiation (average 7% increase per year; 95% confidence interval, 2%-13%). Lower CD4 count at ART initiation was associated with greater risk of KS, lymphoma, and human papillomavirus-related cancer. Calendar year of ART initiation was not associated with cancer incidence. KS and lymphoma rates were highest immediately following ART initiation, particularly among patients with low CD4 cell counts, whereas other cancers increased with time on ART, likely reflecting increased cancer risk with aging. Our results underscore recommendations for earlier HIV diagnosis followed by prompt ART initiation along with ongoing aggressive cancer screening and prevention efforts throughout the course of HIV care.

    The aim of the present study was to evaluate the effect of bevacizumab on local tumor response and lung metastatic potential during boron neutron capture therapy (BNCT) and in particular, the response of intratumor quiescent (Q) cells. B16-BL6 melanoma tumor-bearing C57BL/6 mice were continuously administered bromodeoxyuridine (BrdU) to label all proliferating (P) tumor cells. The tumors were irradiated with thermal neutron beams following the administration of a 10B-carrier [L-para-boronophenylalanine-10B (BPA) or sodium mercaptoundecahydrododecaborate-10B (BSH)], with or without the administration of bevacizumab. This was further combined with an acute hypoxia-releasing agent (nicotinamide) or mild temperature hyperthermia (MTH, 40°C for 60 min). Immediately following the irradiation, cells from certain tumors were isolated and incubated with a cytokinesis blocker. The responses of the Q cells and the total (P+Q) cell populations were assessed based on the frequency of micronuclei using immunofluorescence staining for BrdU. In other tumor-bearing mice, 17 days following irradiation, lung metastases were enumerated. Three days following bevacizumab administration, the sensitivity of the total tumor cell population following BPA-BNCT had increased more than that following BSH-BNCT. The combination with MTH, but not with nicotinamide, further enhanced total tumor cell population sensitivity. Regardless of the presence of a 10B-carrier, MTH enhanced the sensitivity of the Q cell population. Regardless of irradiation, the administration of bevacizumab, as well as nicotinamide treatment, demonstrated certain potential in reducing the number of lung metastases especially in BPA-BNCT compared with BSH-BNCT. Thus, the current study revealed that BNCT combined with bevacizumab has the potential to sensitize total tumor cells and cause a reduction in the number of lung metastases to a similar level as nicotinamide.

    Hepatitis C is the most common health problem worldwide and is major cause of death due to proliferation of hepatocellular carcinoma. The medicines available for HCV treatment overcome up-to 95% complications of HCV. However, liver cancer needs some additional care. Normally Sorafenib tosylate 200 mg is recommended for liver cancer. There is no such trial in which this drug could effectively be used in combination of direct acting antivirals for HCV. The study was conducted for HCV patients (n=30) with liver cancer having decompensated stage. Combination of Sorafenib tosylate, Ribavirn and Sofosbuvir were used for the pharmacokinetics of these medicines. Child pugh score less then 7 (CP A) in adults during treatment phase (received 12 weeks of Sorafenib tosylate 200 mg, Ribavirn and Sofosbuvir 400 mg once daily) have no side effect while child pugh score 7-9 (CP B) have evidence of hypertension. The main efficiency end point sustained virology response with overcoming liver cancer as well in 12 weeks after end treatment (SVR-LLC 12). Mean pharmacokinetic exposure to Sorafenib tosylate 200 mg, Ribavirn and Sofosbuvir at week 8th was 2.1, 1.5,1.2 times greater in CP B than in CP A. Adverse effects (AEs) were observed in 12 out of 30 patients but not severe as lethal for life. Treatment with Sorafenib tosylate, Ribavirn and Sofosbuvir for twelve weeks was harmless and well accepted, 100 % patients achieve (SVR LLC 12) with 10-fold cure rate more than previous ones. The combination therapy of Sorafenib tosylate, Ribavirn and Sofosbuvir was found helpful for the management of decompensated liver cancer.
