    We describe a case report that documented the efficacy and safety of medical therapy in stabilizing and resolving a complex and unstable aortic atheroma after a relatively short period. The patient had a large protruding, mobile, calcified nonulcerated atheroma involving the descending aorta and was therefore treated with aggressive combination therapy with high statin dosages (atorvastatin = 80 mg) and dual antiplatelet treatment (clopidogrel = 75 mg and aspirin = 100 mg). At follow-up, the echocardiogram showed a significant regression in the atheroma volume, with no signs suggestive of ulceration on its surface with the complete mobile component resolution.

  2. Reduction of the treated volume to involved node radiation therapy as part of combined modality treatment for early stage aggressive non-Hodgkin’s lymphoma

    International Nuclear Information System (INIS)

    Background and purpose: This retrospective study investigated whether focused involved node radiation therapy (INRT) can safely replace involved field RT (IFRT) in patients with early stage aggressive NHL. Patients and methods: We included 258 patients with stage I/II aggressive NHL who received combined modality treatment (87%) or primary RT alone (13%). RT consisted of a total dose of 30–40 Gy in 15–20 fractions IFRT or INRT. We compared survival, relapse pattern, radiation-related toxicity and quality of life for both RT techniques. Results: Type of RT was not related to the outcome in either the uni- or multivariate survival analysis. Relapses developed in 59 of 252 patients (23%) of which 47 (80%) were documented as distant recurrence only. Failure of the INRT technique was noted in one patient. There was no significant difference in acute radiation-related toxicity between RT-groups but IFRT showed a significantly higher incidence of higher grade toxicities. Patients treated with INRT had a significantly better physical functioning and global quality of life compared to the IFRT group. Conclusions: Given the retrospective nature of this study, no solid conclusions can be drawn. However, in view of the equivalent efficacy and more favorable toxicity profile, the replacement of IFRT by INRT in combination with chemo-(immuno)-therapy looks very attractive for patients with early stage aggressive NHL

    Prognosis is poor for patients with biologically aggressive Non-Hodgkin lymphoma (NHL), refractory to chemotherapy or relapsed after autologous transplantation, especially when no disease control before allogeneic transplantation is achieved. In 16 patients (median age 53, median prior regimes 5) with relapsed or refractory non-remission NHL, we analysed retrospectively the efficacy of a sequential therapy comprising clofarabine re-induction followed by a reduced-intensity conditioning with fludarabine, CY and melphalan, and T-cell-replete HLA-haploidentical transplantation. High-dose CY was utilized post-transplantation. All patients engrafted. Early response (day +30) was achieved in 94%. Treatment-related grade III-IV toxicity occurred in 56%, most commonly transient elevation of transaminases (36%), while there was a low incidence of infections (19% CMV reactivation, 19% invasive fungal infection) and GVHD (GVHD: acute III-IV: 6%; mild chronic: 25%). One-year non-relapse mortality was 19%. After a median follow-up of 21 months, estimated 1- and 2-year PFS was 56 and 50%, respectively, with 11 patients (69%) still alive after 2 years. In summary, sequential therapy is feasible and effective and provides an acceptable toxicity profile in high-risk non-remission NHL. Presumably, cytotoxic reinduction with clofarabine provides enough remission time for the graft-versus lymphoma effect of HLA-haploidentical transplantation to kick in, even in lymphomas that are otherwise chemo-refractory.

    2012-01-01

    Full Text Available Aggressive B-cell lymphoma (BCL comprises a heterogeneous group of malignancies, including diffuse large B-cell lymphoma (DLBCL, Burkitt lymphoma, and mantle cell lymphoma (MCL. DLBCL, with its 3 subtypes, is the most common type of lymphoma. Advances in chemoimmunotherapy have substantially improved disease control. However, depending on the subtype, patients with DLBCL still exhibit substantially different survival rates. In MCL, a mature B-cell lymphoma, the addition of rituximab to conventional chemotherapy regimens has increased response rates, but not survival. Burkitt lymphoma, the most aggressive BCL, is characterized by a high proliferative index and requires more intensive chemotherapy regimens than DLBCL. Hence, there is a need for more effective therapies for all three diseases. Increased understanding of the molecular features of aggressive BCL has led to the development of a range of novel therapies, many of which target the tumor in a tailored manner and are summarized in this paper.

    Schema therapy (ST) is increasingly used in personality-disordered (PD) patients. ST is an integrative psychotherapy that blends elements of cognitive-behavioral, psychodynamic and experiential approaches. The key concepts in ST are early maladaptive schemas, (dysfunctional) coping styles and schema modes or emotional states. Schema therapy has recently been adapted for forensic settings. In aggressive offenders with PDs, ST specifically focuses on those schema modes that are risk factors for...

In present study we compared the effect of reinforcement behavioral therapy and Ellis cognitive therapy on decreasing of aggression in derelict children aged 10 to 18 years old at hostelry care center of Welfare Organization of Kermanshah. Methods: Fifty-seven out of 89 children (31 male, 26 female was diagnosed as aggressive according to the AGQ results from six hostelry care center of welfare organization of Kermanshah, were selected and participated in the study. Participants allocated in to reinforcement behavioral therapy, Ellis cognitive therapy or control group randomly. Each groups received two hours therapeutic teaching for 10 sessions during 10 weeks. The control group had not been received any intervention. After 10 weeks, the posttest AGQ was performed on participant. The results of pretest and posttest were compared using T-test and ANOVA.Results: The posttest aggression score in reinforcement behavioral therapy group was decreased significantly after intervention (P=0.011. We didn’t find significant differences between pre and post tests aggression score in Ellis cognitive therapy (P=0.258. Result of ANOVA show that there was no significant difference between three group after intervention (P=0.691Conclusion: Reinforcement behavioral therapy and Ellis cognitive therapy did not change the aggression score in derelict children. This may relate to specific hard and stressful life of these children due to ineffectiveness of these short-term methods.

    Donohue, J F; Ohar, J A

    2001-03-01

    Combination products often have useful clinical benefits in asthma. The scientific rationale for combination therapy includes the fact that different agents have complimentary modes of action. Long-acting beta(2)-agonists have effects on airway smooth muscle, and inhaled corticosteroids have potent topical antiinflammatory effect. This combination has been shown to effectively reduce exacerbations and improve symptoms. Substantial clinical trial data provide a rationale for dual-control therapy supported by basic scientific data. Another combined therapy is inhaled steroids plus leukotriene-receptor antagonists, which provides the patient with two effective therapies. Leukotriene-receptor antagonist can also be combined with antihistamines for improved asthma control. Older therapies including theophylline and controlled release albuterol have been effectively added to inhaled corticosteroids, enabling a reduction in the dose of the inhaled steroids. Many other combination therapies are presently being tested. PMID:11224725

  13. [Pro and contra: aggressive or conservative thrombosis therapy? - Pro aggressive thrombosis therapy].

    Science.gov (United States)

    Grommes, J

    2014-10-01

    The post-thrombotic syndrome (PTS), long-term sequelae of a deep vein thrombosis (DVT), reduces quality of life and is of great socio-economic importance. Despite conservative treatment which does not directly facilitate recanalization more than 25% of patients develop PTS. Early thrombus removal may decrease the incidence and severity of PTS. Although the evidence for surgical thrombectomy is weak which allows an early and rapid recanalization, this therapy appears to reduce the risk of PTS and iliofemoral thrombosis. Systemic thrombolysis can reduce the incidence of PTS but it is no longer recommended due to serious bleeding complications. Previous studies with new endovascular catheter-guided procedures allowing local application of thrombolysis and thrombus aspiration displayed promising results. However, so far one prospective randomised study (CaVent study) with long-term results has revealed a significant reduction of PTS. The current evidence recommends early thrombus removal for patients at high risk for PTS. New endovascular procedures such as catheter-guided thrombolysis allow rapid thrombus removal but more prospective randomised studies are necessary to ensure the long-term success of this therapy.

  15. Strategies for combinational cancer therapies

    International Nuclear Information System (INIS)

    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.

    Full Text Available Background: Students’ aggression at schoolshas attracted the attention of many professionals and researchers. The purpose of this study was to analyze the effect of mindfulness-based cognitive therapy on the reduction of male secondary students' aggression in Kermanshah. Methods: In this experimental study, a pretest-posttest control group design was used. A total of 400 students were randomly selected from among the high school male students in Kermanshah using multistage sampling. Of these, 40 students who had a higher mean score were randomly divided into control and experimental groups. The experimental group underwent with mindfulness-based cognitive therapy once a week for eight sessions. The subjects completed Buss and Perry Aggression Questionnaire (1992 twice, one before treatment and another after treatment. The data were analyzed by multivariate analysis of covariance (MANCOVA. Results: The results of multivariate analysis of covariance showed that after removing the effect of pretest, the experimental group indicated a significant reduction compared to the control group in the total aggression scale (F=1059.531; P<0.001. Also, after removing the effect of the pretest, the experimental group experienced a significant decrease compared to the control group at the micro scales of aggressive feeling (F=639.936; P<0.001, the subscales of aggressive thoughts (F=154.240; P<0.001, and aggressive behaviors (F=502.836; P<0.001,. Conclusion: This study showed that mindfulness-based cognitive therapy reduced aggression in all three components of aggressive behavior, aggressive thoughts and aggressive feelings in the students.

    Maladaptive aggression in adolescents is an increasing public health concern. Cognitive Behavior Therapy (CBT) is one of the most common and promising treatments of aggression. However, there is a lack of information on predictors of treatment response regarding CBT. Therefore, a meta-analysis was performed examining the role of predictors on treatment response of CBT. Twenty-five studies were evaluated (including 2,302 participants; 1,580 boys and 722 girls), and retrieved through searches on PubMed, PsycINFO and EMBASE. Effect sizes were calculated for studies that met inclusion criteria. Study population differences and specific CBT characteristics were examined for their explanatory power. There was substantial variation across studies in design and outcome variables. The meta-analysis showed a medium treatment effect for CBT to reduce aggression (Cohen'd = 0.50). No predictors of treatment response were found in the meta-analysis. Only two studies did examine whether proactive versus reactive aggression could be a moderator of treatment outcome, and no effect was found of this subtyping of aggression. These study results suggest that CBT is effective in reducing maladaptive aggression. Furthermore, treatment setting and duration did not seem to influence treatment effect, which shows the need for development of more cost-effective and less-invasive interventions. More research is needed on moderators of outcome of CBT, including proactive versus reactive aggression. This requires better standardization of design, predictors, and outcome measures across studies. PMID:25138144

    We seek to confirm the effect and explore the indications of aggressive locoregional management in patients with metastatic inflammatory breast cancer (IBC). Between 2003 and 2014, we reviewed the records of 156 patients with metastatic IBC from five large centers of Breast Surgery in the region of central south of China. Clinicopathologic data were collected to access overall survival (OS), prognostic factors and the indications for locoregional treatment. 75 (48%) patients underwent aggressive locoregional therapy. Patients in locoregional therapy group had a median OS of 24 months compared with 17 months of those in no locoregional therapy group. 2-year OS rate of these two groups was 52% and 32%, separately. Locoregional therapy (HR = 0.556; 95% CI 0.385-0.803; p = 0.002) was confirmed to be an independent prognostic factor, which could significantly improve OS of patients with metastatic IBC. For locoregional therapy group, statistical differences were observed in all subgroups stratified by the factors that were significant in univariate analysis except in the subgroups of stable disease, Charlson comorbidity index ≥3 and cerebral metastasis. Therefore, systemic therapy efficacy, Charlson comorbidity index and cerebral metastasis status appeared to be important indexes for choice of locoregional therapy in different individuals.

    Full Text Available BACKGROUND: Few systematic studies exist on the effects of chronic reuptake of monoamine neurotransmitter systems during pregnancy on the regulation of maternal behavior, although many drugs act primarily through one or more of these systems. Previous studies examining fluoxetine and amfonelic acid treatment during gestation on subsequent maternal behavior in rodents indicated significant alterations in postpartum maternal care, aggression and oxytocin levels. In this study, we extended our studies to include chronic gestational treatment with desipramine or amitriptyline to examine differential effects of reuptake inhibition of norepinephrine and combined noradrenergic and serotonergic systems on maternal behavior, aggression, and oxytocin system changes. METHODS: Pregnant Sprague-Dawley rats were treated throughout gestation with saline or one of three doses of either desipramine, which has a high affinity for the norepinephrine monoamine transporter, or amitriptyline, an agent with high affinity for both the norepinephrine and serotonin monoamine transporters. Maternal behavior and postpartum aggression were assessed on postpartum days one and six respectively. Oxytocin levels were measured in relevant brain regions on postpartum day seven. Predictions were that amitriptyline would decrease maternal behavior and increase aggression relative to desipramine, particularly at higher doses. Amygdaloidal oxytocin was expected to decrease with increased aggression. RESULTS: Amitriptyline and desiprimine differentially reduced maternal behavior, and at higher doses reduced aggressive behavior. Hippocampal oxytocin levels were lower after treatment with either drug but were not correlated with specific behavioral effects. These results, in combination with previous findings following gestational treatment with other selective neurotransmitter reuptake inhibitors, highlight the diverse effects of multiple monoamine systems thought to be involved in

    2003-01-01

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

    2016-06-10

    In recent years combination therapies have become increasingly popular in most therapeutic areas. We present a qualitative and quantitative approach and elucidate some of the challenges and solutions to a more optimal therapy. For tumor growth this involves the study of semi-mechanistic cell-growth/kill models with multiple sites of action. We introduce such models and analyze their dynamic properties using simulations and mathematical analysis. This is done for two specific case studies, one involving a single compound and one a combination of two compounds. We generalize the notion of Tumor Static Concentration to cases when two compounds are involved and develop a graphical method for determining the optimal combination of the two compounds, using ideas akin to those used in studies employing isobolograms. In studying the dynamics of the second case study we focus, not only on the different concentrations, but also on the different dosing regimens and pharmacokinetics of the two compounds.

    Full Text Available We evaluated results of temozolomide (TMZ therapy in six patients, aged 34–78 years, presenting aggressive pituitary tumors. In all the patients tested O6-methylguanine-DNA methyltransferase (MGMT immunoexpression in surgical specimens was absent. Patients received temozolomide 140–320 mg/day for 5 days monthly for at least 3 months. In two patients minimum time for evaluation could not be reached because of death in a 76-year-old man with a malignant prolactinoma and of severe neutro-thrombopenia in a 47-year-old woman with nonfunctioning pituitary adenoma. In two patients (a 34-year-old acromegalic woman and a 39-year-old woman with Nelson’s syndrome no response was observed after 4 and 6 months, respectively, and the treatment was stopped. Conversely, two 52- and 42-year-old women with Cushing’s disease had long-term total clinical and radiological remissions which persisted after stopping temozolomide. We conclude that TMZ therapy may be of variable efficacy depending on—until now—incompletely understood factors. Cooperative work on a greater number of cases of aggressive pituitary tumors should be crucial to establish the indications, doses, and duration of temozolomide administration.

    International Nuclear Information System (INIS)

    Purpose: This study was conducted to evaluate the effectiveness of trimodal combination therapy (radiotherapy, intra-arterial chemotherapy, antrotomy) for the treatment of primary maxillary sinus carcinoma. Methods and Materials: Between 1977 and 1996, 110 patients with maxillary squamous cell carcinoma were treated with trimodal combination therapy at Tokyo Medical and Dental University Hospital. All tumors were classified according to the 1997 UICC TNM staging system. Eighty percent of patients had T3 or T4 tumors. The T3 and T4 tumors were also classified into three groups according to their location, as visualized using computed tomography: the posterior-lateral (P) group, the medial (M) group, and the upper (U) group. Eight patients received additional radiotherapy, and 37 patients underwent a second surgical procedure, in addition to the trimodal combination therapy. Results: The 5-year cause-specific survival and local control rates were 71% and 65%, respectively. The 5-year local control rate was 80% for the T1+2 tumors, 64% for the T3 tumors, and 52% for the T4 tumors (p=0.06). Patients in the P+M group who received a 5-fluorouracil (5-FU) dosage of more than 3500 mg had a better 5-year local control rate than patients who received a 5-FU dosage of less than 3500 mg (p=0.01). No improvement in the local control rate after a second surgical procedure or additional irradiation treatment was observed in any of the groups. Conclusion: Trimodal combination therapy provides good local control, with the final outcome depending on the T stage of the tumor and the dosage of 5-FU

  8. Rates and Durability of Response to Salvage Radiation Therapy Among Patients With Refractory or Relapsed Aggressive Non-Hodgkin Lymphoma

    International Nuclear Information System (INIS)

    Purpose: To evaluate the response rate (RR) and time to local recurrence (TTLR) among patients who received salvage radiation therapy for relapsed or refractory aggressive non-Hodgkin lymphoma (NHL) and investigate whether RR and TTLR differed according to disease characteristics. Methods and Materials: A retrospective review was performed for all patients who completed a course of salvage radiation therapy between January 2001 and May 2011 at Brigham and Women's Hospital/Dana-Farber Cancer Institute. Separate analyses were conducted for patients treated with palliative and curative intent. Predictors of RR for each subgroup were assessed using a generalized estimating equation model. For patients treated with curative intent, local control (LC) and progression-free survival were estimated with the Kaplan-Meier method; predictors for TTLR were evaluated using a Cox proportional hazards regression model. Results: Salvage radiation therapy was used to treat 110 patients to 121 sites (76 curative, 45 palliative). Salvage radiation therapy was given as part of consolidation in 18% of patients treated with curative intent. Median dose was 37.8 Gy, with 58% and 36% of curative and palliative patients, respectively, receiving 39.6 Gy or higher. The RR was high (86% curative, 84% palliative). With a median follow-up of 4.8 years among living patients, 5-year LC and progression-free survival for curative patients were 66% and 34%, respectively. Refractory disease (hazard ratio 3.3; P=.024) and lack of response to initial chemotherapy (hazard ratio 4.3; P=.007) but not dose (P=.93) were associated with shorter TTLR. Despite doses of 39.6 Gy or higher, 2-year LC was only 61% for definitive patients with refractory disease or disease that did not respond to initial chemotherapy. Conclusions: Relapsed or refractory aggressive NHL is responsive to salvage radiation therapy, and durable LC can be achieved in some cases. However, refractory disease is associated with a

    Purpose: To evaluate the response rate (RR) and time to local recurrence (TTLR) among patients who received salvage radiation therapy for relapsed or refractory aggressive non-Hodgkin lymphoma (NHL) and investigate whether RR and TTLR differed according to disease characteristics. Methods and Materials: A retrospective review was performed for all patients who completed a course of salvage radiation therapy between January 2001 and May 2011 at Brigham and Women's Hospital/Dana-Farber Cancer Institute. Separate analyses were conducted for patients treated with palliative and curative intent. Predictors of RR for each subgroup were assessed using a generalized estimating equation model. For patients treated with curative intent, local control (LC) and progression-free survival were estimated with the Kaplan-Meier method; predictors for TTLR were evaluated using a Cox proportional hazards regression model. Results: Salvage radiation therapy was used to treat 110 patients to 121 sites (76 curative, 45 palliative). Salvage radiation therapy was given as part of consolidation in 18% of patients treated with curative intent. Median dose was 37.8 Gy, with 58% and 36% of curative and palliative patients, respectively, receiving 39.6 Gy or higher. The RR was high (86% curative, 84% palliative). With a median follow-up of 4.8 years among living patients, 5-year LC and progression-free survival for curative patients were 66% and 34%, respectively. Refractory disease (hazard ratio 3.3; P=.024) and lack of response to initial chemotherapy (hazard ratio 4.3; P=.007) but not dose (P=.93) were associated with shorter TTLR. Despite doses of 39.6 Gy or higher, 2-year LC was only 61% for definitive patients with refractory disease or disease that did not respond to initial chemotherapy. Conclusions: Relapsed or refractory aggressive NHL is responsive to salvage radiation therapy, and durable LC can be achieved in some cases. However, refractory disease is associated with a

    Full Text Available Working as a music therapist in a psychiatric unit for children with learning disabilities, one is often confronted with a lot of aggression. Most of these children have attachment disorders and severe behavioural problems. By which means can music exist in music therapy within this specific setting? Can we speak of a traumatic nature in music and body? This article will present a case study, where finding a safe place within music therapy is of major importance. Learning and listening to songs can be a necessary way to safeguard control for the client, gain some self-confidence, and create a place for regression. Going through this process in finding a safe and contained place within music therapy, the possibility of playing techniques arises, offering the freedom for exploration and a form of control and predictability. The case study concludes with the importance of playfulness whereby traumatic material can be digested through the music. Also, the role of singing songs in music therapy with this population is highlighted briefly.

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

    Mantle cell lymphoma (MCL) is a heterogeneous disease, and it has been well-established over the last decade that a subset of patients can have indolent presentation. It is therefore important to adopt a risk-stratified approach in order to minimize unnecessary toxicities while maximizing survival and quality of life in selected MCL patients. This review provides an up-to-date assessment of clinical and pathologic entities associated with indolent disease course and delineates available biomarkers with predictive significance. Initial treatment decisions should be guided by risk assessment to discern patients who might do well with deferred therapy, from those who would require treatment with non-aggressive first-line regimens.

    After years of therapeutic nihilism due to the inefficacy of conventional cytotoxic chemotherapy, the multikinase inhibitor sorafenib was the first agent to demonstrate a significant improvement in the survival of patients with advanced hepatocellular carcinoma (HCC). However, survival benefits on sorafenib treatment remain modest in clinical practice and developing more effective systemic therapies is challenging. No other targeted agent or regimen has proven efficacy to improve survival in a phase III trial in the first- or second-line setting, and no standard treatment option currently exists outside of clinical trials for patients with acquired resistance or intolerance to sorafenib. In contrast to other malignancies, no oncogene addiction has been identified in hepatocarcinogenesis thus far, which may explain why currently tested agents do not achieve sustained partial or complete response in the majority of patients. Several agents with mainly antiangiogenic properties are currently in phase II and III development, including brivanib, ramucirumab, everolimus, tivantinib and resminostat. In addition, the role of molecularly targeted therapy (MTT) in earlier stages of the disease in combination with transcatheter arterial chemoembolization or in the adjuvant setting after potentially curative approaches is under investigation. The identification of the key driver mutations and the assessment of relevant targets for specific subpopulations of patients according to their biomarker-based profile will hopefully lead to a more personalized medicine. This article attempts to provide a concise overview on recent developments of MTT in the phase II-III setting in advanced HCC with an additional focus on synergistic combinations and combined treatment approaches.

    We used {sup 18}F-FDG PET to evaluate the FDG uptake in patients with aggressive fibromatosis (AF, also known as desmoid tumours) undergoing therapy with imatinib (imatinib mesylate, Glivec). The pilot study included nine patients with progressive AF receiving oral treatment with imatinib at a daily dose of 800 mg. Patients were examined using PET prior to the start of therapy and during imatinib treatment. Restaging according to the Response Evaluation Criteria in Solid Tumors (RECIST) was performed in parallel using CT and/or MRI and served as reference. The clinical outcomes in nine evaluable patients were as follows: seven patients with stable disease, and two patients with progressive disease. A 27% decrease in the median average standardized uptake value (SUV) of the sequential PET examinations was demonstrated in all evaluable patients with three patients (33%) showing a decrease in SUV of more than 40% (48%, 52% and 54%, respectively); no patient showed a substantial increase in SUV. To our knowledge, this is the first series of AF patients undergoing treatment with imatinib and monitored using sequential PET imaging, that allows detection of SUV changes after imatinib induction, thus helping to decide whether treatment should be continued or not.

    Full Text Available Abstract Background Due to time-dependent confounding by blood pressure and differential loss to follow-up, it is difficult to estimate the effectiveness of aggressive versus conventional antihypertensive combination therapies in non-randomized comparisons. Methods We utilized data from 22,576 hypertensive coronary artery disease patients, prospectively enrolled in the INternational VErapamil-Trandolapril STudy (INVEST. Our post-hoc analyses did not consider the randomized treatment strategies, but instead defined exposure time-dependently as aggressive treatment (≥3 concomitantly used antihypertensive medications versus conventional treatment (≤2 concomitantly used antihypertensive medications. Study outcome was defined as time to first serious cardiovascular event (non-fatal myocardial infarction, non-fatal stroke, or all-cause death. We compared hazard ratio (HR estimates for aggressive vs. conventional treatment from a Marginal Structural Cox Model (MSCM to estimates from a standard Cox model. Both models included exposure to antihypertensive treatment at each follow-up visit, demographics, and baseline cardiovascular risk factors, including blood pressure. The MSCM further adjusted for systolic blood pressure at each follow-up visit, through inverse probability of treatment weights. Results 2,269 (10.1% patients experienced a cardiovascular event over a total follow-up of 60,939 person-years. The HR for aggressive treatment estimated by the standard Cox model was 0.96 (95% confidence interval 0.87-1.07. The equivalent MSCM, which was able to account for changes in systolic blood pressure during follow-up, estimated a HR of 0.81 (95% CI 0.71-0.92. Conclusions Using a MSCM, aggressive treatment was associated with a lower risk for serious cardiovascular outcomes compared to conventional treatment. In contrast, a standard Cox model estimated similar risks for aggressive and conventional treatments. Trial registration Clinicaltrials

    In May 2011,editorial boards of Chinese Journal of Experimental and Clinical Infectious Diseases (Electronic Edition),Chinese Journal of Liver Diseases (Electronic Edition) and Infection International (Electronic Edition) organized an expert committee to form an expert consensus on antiviral combination therapy of chronic hepatitis B (CHB).The consensus publication promoted and standardized the combination therapy concept of chronic hepatitis B.Clinical evidence of combination therapy for CHB is incomplete.The concept of combination therapy is gradually extended,from combination of antiviral drugs plus antiviral drugs,to antiviral drugs plus hepatoprotective drugs,and antiviral drugs plus immunomodulatory drugs.Therefore,editorial boards once again asked experts to analyze the new clinical evidence,and form the expert consensus on combination therapy of chronic hepatitis B.The formulation of this consensus is according to the principles of evidence-based medicine.Large number of clinical studies of combination therapy is still in progress.This consensus can not fully answer all the problems encountered in the combination therapy of CHB.With the progress of clinical practice of antiviral therapy,and the accumulation of evidence in combination therapy,the expert committee will update the consensus timely.

    Full Text Available In the present paper is analysed concrete behavior from strength structure elements, subjected to combined sulphatic and magnesian aggressive actions. In order to clearly relieve cement influence regarding corrosion behavior and to be as close as possible of concrete structural characteristics, tests are realized on standard mortars, which from compositional point of view are mocro-concretes. These were used different W/C ratios in order to obtain different structural characteristics, knowing that in the first period after casting, when concrete porosity is sensibly higher, corrosion process is more emphatic, with subsequent negative effects. It was taken into account the fact that sulphatic corrosion effect appears after a long duration of aggressive agent action, in the present paper proposing a three year duration for aggressive attack. In the same time it was considered the fact that usual cement for structural elements is composite cement type CEM II/A-S 32,5, studying combined sulphatic and magnesian corrosion evolution on a large type of micro-concrete compositions with different compactness and aggressive agent concentrations.

    Full Text Available Periodontal maintenance care is an essential part of periodontal therapy for patients diagnosed with Aggressive Periodontitis, being, however, hard to instruct and to motivate these patients to follow a careful and effective program of maintenance for all their lives. A literature review was done, by means of relevant papers published on the last four decades, pointing out the importance of individual susceptibility for the appearance of aggressive periodontitis and to discuss the importance of a maintenance therapy on its treatment, applying Homeopathy and Isopathy. Homeopathy consists on a complex therapeutic system mainly based on the “Law of Similarity”, that is, the illness may be healed by drugs that produce similar symptoms in a healthy organism and, in this conception, the disease is understood as an energetic unbalance, in which internal and external factors acting on the subject’s susceptibility are considered and can be expressed by an individual symptomathology that goes from the rational sphere to the somatic sphere. On the other hand, Isopathy is the method of treatment with therapeutic agent, which actions on a healthy subject consist on pharmacodynamic manifestations similar to those observed in a sick person. Based on these concepts, the authors establish a hypothesis of the effectiveness of Homeopathy and Isopathy, the latter through auto-medications or auto-biotherapies, that are products which the active principal is obtained from the patient himself (gingival tissue and secretions, and that may be used as auxiliary treatments in the maintenance therapy of Aggressive Periodontitis.

    The aim of this systematic review was to investigate whether the use of antimicrobial photodynamic therapy (aPDT) as an adjuvant to scaling and root planning (SRP) yields better results than SRP alone or associated with systemic antibiotics in the treatment of aggressive periodontitis (AgP). A meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statements and Cochrane Collaboration recommendations. The search for relevant studies (earliest record to January 2015) was carried out in seven databases, followed by a manual search. Methodological quality assessment of the studies selected was based on an analysis of the risk of bias. At each time point of follow-up, the existence of significant differences (p outcomes) between groups was assessed with RevMan software 5.0. Heterogeneity between studies was assessed by the Higgin test (I (2)). Four randomized controlled trials (RCTs) satisfied the eligibility criteria of this review. Only one study was found to have a low risk of bias. There were no significant differences in PD reduction (mean difference 0.33, 95 % confidence interval -0.32 to 0.98, p = 0.32) and CAL gain (mean difference 0.20, 95 % confidence interval -0.41 to 0.81, p = 0.53) between the test and control interventions. At present, therefore, when compared to SRP alone or associated with systemic antibiotics, the evidence suggests that the association of aPDT + SRP is of no additional benefit in the nonsurgical treatment of AgP.

    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.

  4. Combined effects of IL-8 and CXCR2 gene polymorphisms on breast cancer susceptibility and aggressiveness

    International Nuclear Information System (INIS)

    Interleukin-8 (IL-8/CXCL-8) is a prototype of the ELR+CXC chemokines that play an important role in the promotion and progression of many human cancers including breast cancer. We have recently showed the implication of polymorphism (-251) T/A of IL-8 gene in the susceptibility and prognosis of breast carcinoma. IL-8 acts through its CXCR1 and CXCR2 receptors. CXCR2, expressed on the endothelial cells, is the receptor involved in mediating the angiogenic effects of ELR+CXC chemokines and in particular IL-8. In the current study, we investigated the susceptibility and prognostic implications of the genetic variation in CXCR2 in breast carcinoma. We also confirmed the implication of IL-8 (-251) T/A polymorphism in a larger cohort. Finally, we combined the IL-8 and CXCR2 variant alleles and analyzed their effects in breast cancer risk and prognosis. We used the allele-specific polymerase chain reaction to characterize the variation of IL-8 and CXCR2 for 409 unrelated Tunisian patients with breast carcinoma and 301 healthy control subjects. To estimate the relative risks, Odds ratios and 95% confidence intervals were calculated using unconditional logistic regression after adjusting for the known risk factors for breast cancer. Associations of the genetic marker with the rates of breast carcinoma-specific overall survival and disease-free survival were assessed using univariate and multivariate analyses. A highly significant association was found between the homozygous CXCR2 (+ 1208) TT genotype (adjusted OR = 2.89; P = 0.008) and breast carcinoma. A significantly increased risk of breast carcinoma was associated with IL-8 (-251) A allele (adjusted OR = 1.86; P = 0.001). The presence of two higher risk genotypes (the TA and TT in IL-8, and the TT in CXCR2) significantly increased the risk of developing breast carcinoma (adjusted OR = 4.15; P = 0.0004). The CXCR2 (+ 1208) T allele manifested a significant association with an aggressive phenotype of breast carcinoma as

  6. Pirfenidone enhances the efficacy of combined radiation and sunitinib therapy

    International Nuclear Information System (INIS)

    Radiotherapy is a widely used treatment for many tumors. Combination therapy using anti-angiogenic agents and radiation has shown promise; however, these combined therapies are reported to have many limitations in clinical trials. Here, we show that radiation transformed tumor endothelial cells (ECs) to fibroblasts, resulting in reduced vascular endothelial growth factor (VEGF) response and increased Snail1, Twist1, Type I collagen, and transforming growth factor (TGF)-β release. Irradiation of radioresistant Lewis lung carcinoma (LLC) tumors greater than 250 mm3 increased collagen levels, particularly in large tumor vessels. Furthermore, concomitant sunitinib therapy did not show a significant difference in tumor inhibition versus radiation alone. Thus, we evaluated multimodal therapy that combined pirfenidone, an inhibitor of TGF-induced collagen production, with radiation and sunitinib treatment. This trimodal therapy significantly reduced tumor growth, as compared to radiation alone. Immunohistochemical analysis revealed that radiation-induced collagen deposition and tumor microvessel density were significantly reduced with trimodal therapy, as compared to radiation alone. These data suggest that combined therapy using pirfenidone may modulate the radiation-altered tumor microenvironment, thereby enhancing the efficacy of radiation therapy and concurrent chemotherapy. - Highlights: • Radiation changes tumor endothelial cells to fibroblasts. • Radio-resistant tumors contain collagen deposits, especially in tumor vessels. • Pirfenidone enhances the efficacy of combined radiation and sunitinib therapy. • Pirfenidone reduces radiation-induced collagen deposits in tumors

    A scheme of therapy of radiation cystitis is suggested. It was developed on the basis of evaluation of literature and clinical data 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%).

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

    ABSTRACT Despite aggressive conventional therapy, lasting hemiplegia persists in a large percentage of stroke survivors. The aim of this article is to critically review the rationale behind targeting multiple sites along the motor learning network by combining robotic therapy with pharmacotherapy and virtual reality–based reward learning to alleviate upper extremity impairment in stroke survivors. Methods for personalizing pharmacologic facilitation to each individual’s unique biology are also reviewed. At the molecular level, treatment with levodopa was shown to induce long-term potentiation-like and practice-dependent plasticity. Clinically, trials combining conventional therapy with levodopa in stroke survivors yielded statistically significant but clinically unconvincing outcomes because of limited personalization, standardization, and reproducibility. Robotic therapy can induce neuroplasticity by delivering intensive, reproducible, and functionally meaningful interventions that are objective enough for the rigors of research. Robotic therapy also provides an apt platform for virtual reality, which boosts learning by engaging reward circuits. The future of stroke rehabilitation should target distinct molecular, synaptic, and cortical sites through personalized multimodal treatments to maximize motor recovery. PMID:26829074

    Full Text Available Background: Post traumatic stress disorder (PTSD in war veterans has been linked with symptoms in their children, including symptoms resembling those of the traumatized parents, especially aggression. This study aims to examine the effectiveness of cognitive-behavioral group therapy in reducing aggressive behaviors of male adolescents whose fathers have war related PTSD. Method: 36 male children (aged 11 19 years whose fathers had PTSD, were randomly assigned into three groups for Rational-Emotive- Behavioral Therapy (REBT, Relaxation Therapy, and Wait-List control group. Each method had a course of ten therapeutic group sessions of 60 minutes once a week. Rates of aggression were assessed by Aggression Questionnaire (AGQ at baseline, end of intervention, and two months later. Results: The difference between AGQ scores of three groups was statistically significant. The behaviors of the three groups were not homogenous across the time (group × time interaction and showed a statistically significant difference. Conclusion: This study revealed that the intervention groups were superior to control group in reduction of aggressive behaviors in male adolescents of war veterans with PTSD. Further studies with greater sample size, prolonged duration of follow up, and multiple assessment procedures may be needed for better conclusions.

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

  20. Combined therapy of tumors in adult persons

    International Nuclear Information System (INIS)

    A significant amelioration of treatment results is achieved by sequential chemotherapy and radiotherapy in patients with lymphogranulomatosis of stage IIb to IVb and in patients with non-Hodgkin's lymphomas in corresponding stages. Similar results will probably be obtained in patients with small cell bronchial carcinomas in a limited stage. Patients suffering from an initially inoperable ovarian cancer often reach an operable condition by sequential chemotherapy and radiotherapy. In the stages Dukes B2 and C of the rectum carcinoma, preoperative and/or postoperative irradiation significantly reduces the recurrence rates and increases the survival times. A considerable reduction of recurrence rates is obtained by postoperative radiotherapy in soft tissue sarcomas of the stages T1 to T3. Another improvements is anticipated by a neutron or neutron boost irradiation for stage T3 and by adjuvant chemotherapy for G3 tumors. In the osteasarcoma of adult persons, the results of the limb-sparing sequential therapy will not be worse than the results achieved by amputation. Retrospective analyses of the long-term results of radical mastectomy and conservative operation with postoperative irradiation in case of mammary carcinoma did not show any difference for the stages T1 to T3, N0 to N1.

  1. Combination therapy: New hope for alcoholic hepatitis?

    Gao, Bin; Shah, Vijay H

    2015-09-01

    Alcoholic hepatitis (AH) is a severe form of alcoholic liver disease with high mortality. The pathogenesis of AH is not fully understood, but it is generally believed that inflammation is a key factor leading to liver failure in AH. Steroids, which have broad immunosuppressive effects, have been used for the treatment of AH over the last forty years. Steroids elicit modest improvement in short-term survival rate in patients with severe AH, but also cause severe side effects. Several specific inflammatory targets (e.g., IL-1, LPS, and gut microbiota) are currently under investigation for the treatment of AH with the goal to obviate or reduce steroid administration. In addition to inflammation, impaired liver regeneration is another major cause of liver failure in AH, which deteriorates further after steroid treatment because inflammation plays a key role in promoting liver repair. Interleukin-22 (IL-22) is a promising drug for the treatment of AH because of its hepatoprotective and anti-fibrotic functions and relatively few known side effects. In addition, IL-22 treatment also ameliorates bacterial infection and kidney injury, two major complications associated with severe AH. IL-22 is currently under investigation in preclinical and clinical studies and may hold great promise for AH by providing more beneficial effects and fewer side effects than current therapies.

    Aggressive angiomyxoma is a rare soft tissue neoplasm that usually arises within the perineum. It often occurs as a vulvar mass and clinically simulates a Bartholin's gland cyst. Most patients are in the second or third decade of life, but some cases have also been reported in children. This is the report of a 21 year old woman with 4.5 × 3 × 1.5 cm mass in right labia major. The patient underwent wide local excision surgical treatment. Histological examination showed high vascular myxoid tumor containing spindle cells. Immunohistochemical study of cells showed positive reaction to estrogen and progesterone and negative reaction to S100, SMA and desmin. Treatment with a gonadotropin-releasing hormone agonist was administered to deal with residual tumor and prevent local recurrence for 6 months.

    2006-08-01

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

    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.

    Given the complex neuropathology Alzheimer's disease (AD), combination therapy may be necessary for effective treatment. However, scientific, pragmatic, regulatory, and business challenges need to be addressed before combination therapy for AD can become a reality. Leaders from academia and industry, along with a former member of the Food and Drug Administration and the Alzheimer's Association, have explored these challenges and here propose a strategy to facilitate proof-of-concept combination therapy trials in the near future. First, a more integrated understanding of the complex pathophysiology and progression of AD is needed to identify the appropriate pathways and the disease stage to target. Once drug candidates are identified, novel clinical trial designs and selection of appropriate outcome assessments will be needed to enable definition and evaluation of the appropriate dose and dosing regimen and determination of efficacy. Success in addressing this urgent problem will only be achieved through collaboration among multiple stakeholders. PMID:27017906

    To review key trials of monotherapy and combination therapy of alpha(1)-adrenergic receptor antagonists (alpha(1)-ARAs), 5alpha-reductase inhibitors (5alphaRIs) and anti-muscarinic agents in the treatment of lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). To assess the safety and efficacy of combination therapies for LUTS associated with BPH, a search of the MEDLINE and Cochrane databases (1976-2008) was conducted for relevant trials and reviews using the terms benign prostatic hyperplasia, lower urinary tract symptoms, alpha(1)-adrenergic receptor antagonists, 5alpha-reductase inhibitors, anti-muscarinics, anticholinergics, combination therapy, alfuzosin, doxazosin, tamsulosin, terazosin, dutasteride, finasteride, tolterodine, flavoxate, propiverine, oxybutynin, erectile dysfunction, sildenafil, vardenafil and tadalafil. Data from the Medical Therapy of Prostatic Symptoms (MTOPS) study indicated a role for long-term use of alpha(1)-ARAs and 5alphaRIs in combination. In the MTOPS study, combination therapy with the alpha(1)-ARA doxazosin and the 5alphaRI finasteride was significantly more effective than either component alone in reducing symptoms (P=0.006 vs doxazosin monotherapy; Pfinasteride monotherapy) and in lowering the rate of clinical progression (Pdutasteride resulted in a significantly greater decrease in International Prostate Symptom Score (IPSS) when compared with either monotherapy. Several recent trials have studied the efficacy of combining alpha(1)-ARAs and anti-muscarinic agents in the treatment of BPH. These studies have found this combination to result in statistically significant benefits in quality of life scores, patient satisfaction, urinary frequency, storage symptoms and IPSS scores. Studies have not shown an increased risk of urinary retention associated with the use of anti-muscarinics in a highly select cohort of men with BPH. The available data suggest that combination therapy can be beneficial

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

    Full Text Available Background: hypertension is one of the main cardiovascular risk factors, so its control improves the life expectancy of patients.Objective: to assess the effects of a treatment combining medication with auricular therapy and phyto-therapy in hypertensive patients assisted at the health area of ”Romárico Oro” Polyclinic, in Puerto Padre, Las Tunas province.Methods: an intervention study was carried out in 68 hypertensive patients of the health area of “Romárico Oro” Polyclinic in Puerto Padre from April, 2013 to April, 2014. The patients were distributed at random into two equal groups; the first received medication combined with auricular therapy and phyto-therapy, while the second one received only medication. The statistical analysis was done by means of Statistic system, t-student and Chi-Square tests were used and p< or =0.05 was considered as level of statistical significance.Results: by the end of the intervention, 73, 53% of the patients of the group with the combination of drug treatment and auricular therapy and phyto-therapy were controlled. In this group, the diastolic filling pressure diminished to 2, 2 mm Hg and the systolic gradient to 3, 66 mm, regarding the group treated only with drugs. Only one patient, representing the 2, 94% showed adverse reaction to the natural and traditional treatment.Conclusions: the combination of medication with auricular therapy and phyto-therapy proved to be effective, corroborated by a significant decrease of quantity of crisis, diastolic and systolic filling pressure values and increase of number of patients with their disease controlled; the report of only one complication shows the innocuousness of the auricular therapy and phyto-therapy treatment.

  16. Evaluation of tyrosine kinase inhibitor combinations for glioblastoma therapy.

    Directory of Open Access Journals (Sweden)

    Avadhut D Joshi

    Full Text Available Glioblastoma multiforme (GBM is the most common intracranial cancer but despite recent advances in therapy the overall survival remains about 20 months. Whole genome exon sequencing studies implicate mutations in the receptor tyrosine kinase pathways (RTK for driving tumor growth in over 80% of GBMs. In spite of various RTKs being mutated or altered in the majority of GBMs, clinical studies have not been able to demonstrate efficacy of molecular targeted therapies using tyrosine kinase inhibitors in GBMs. Activation of multiple downstream signaling pathways has been implicated as a possible means by which inhibition of a single RTK has been ineffective in GBM. In this study, we sought a combination of approved drugs that would inhibit in vitro and in vivo growth of GBM oncospheres. A combination consisting of gefitinib and sunitinib acted synergistically in inhibiting growth of GBM oncospheres in vitro. Sunitinib was the only RTK inhibitor that could induce apoptosis in GBM cells. However, the in vivo efficacy testing of the gefitinib and sunitinib combination in an EGFR amplified/PTEN wild type GBM xenograft model revealed that gefitinib alone could significantly improve survival in animals whereas sunitinib did not show any survival benefit. Subsequent testing of the same drug combination in a different syngeneic glioma model that lacked EGFR amplification but was more susceptible to sunitinib in vitro demonstrated no survival benefit when treated with gefitinib or sunitinib or the gefitinib and sunitinib combination. Although a modest survival benefit was obtained in one of two animal models with EGFR amplification due to gefitinib alone, the addition of sunitinib, to test our best in vitro combination therapy, did not translate to any additional in vivo benefit. Improved targeted therapies, with drug properties favorable to intracranial tumors, are likely required to form effective drug combinations for GBM.

  17. Reduction in arterial wall strain with aggressive lipid-lowering therapy in patients with carotid artery disease

    International Nuclear Information System (INIS)

    Inflammation and biomechanical factors have been associated with the development of vulnerable atherosclerotic plaques. Lipid-lowering therapy has been shown to be effective in stabilizing them by reducing plaque inflammation. Its effect on arterial wall strain, however, remains unknown. The aim of the present study was to investigate the role of high- and low-dose lipid-lowering therapy using an HMG-CoA reductase inhibitor, atorvastatin, on arterial wall strain. Forty patients with carotid stenosis >40% were successfully followed up during the Atorvastatin Therapy: Effects on Reduction Of Macrophage Activity (ATHEROMA; ISRCTN64894118) Trial. All patients had plaque inflammation as shown by intraplaque accumulation of ultrasmall super paramagnetic particles of iron oxide on magnetic resonance imaging at baseline. Structural analysis was performed and change of strain was compared between high- and low-dose statin at 0 and 12 weeks. There was no significant difference in strain between the 2 groups at baseline (P=0.6). At 12 weeks, the maximum strain was significantly lower in the 80-mg group than in the 10-mg group (0.085±0.033 vs. 0.169±0.084; P=0.001). A significant reduction (26%) of maximum strain was observed in the 80-mg group at 12 weeks (0.018±0.02; P=0.01). Aggressive lipid-lowering therapy is associated with a significant reduction in arterial wall strain. The reduction in biomechanical strain may be associated with reductions in plaque inflammatory burden. (author)

    This study was designed to determine the value of 2-[fluorine-18]-fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET) in the early assessment of therapy response in lymphoma patients. We studied 20 patients with pathologically proven lymphoma, including 17 patients with aggressive non-Hodgkin's lymphoma and three patients with Hodgkin's lymphoma. All patients underwent whole-body FDG-PET imaging at baseline and after 1-2 cycles of chemotherapy. PET images were analysed visually and quantitatively by calculating the standardised uptake value (SUV). In each patient, we measured the SUV of the tumour demonstrating the highest FDG uptake at baseline study and the SUV of the same tumour after 1-2 cycles of therapy. The achievement of complete response was assessed on the basis of a combination of clinical findings and the results of conventional imaging modalities. Follow-up of progression-free survival (PFS) was obtained for the validation of PET data. Of the 20 patients, ten achieved complete remission at the completion of chemotherapy and the other ten did not respond to chemotherapy. Of the ten responders, four are still in remission (PFS 24-34 months) while the other six have relapsed (PFS 8-16 months). For the prediction of 24-month clinical outcome, visual analysis of PET after 1-2 cycles showed high sensitivity (87.5%) and accuracy (80%) but low specificity (50%). Comparison with the baseline SUVs revealed that the responders showed a significantly greater percent reduction in SUV after 1-2 cycles of therapy as compared with the non-responders (81.2%{+-}9.5% vs 35.0%{+-}20.2%, P<0.001). In addition, using 60% reduction as a cut-off value, the responders were clearly separated from the non-responders, with the exception of one non-responder. In conclusion, when performed early during chemotherapy, FDG-PET may be predictive of clinical outcome and allows differentiation of responders from non-responders in cases of aggressive lymphoma.

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

    Combination products play an important role in medicine as they offer improved clinical effectiveness, enhanced patient adherence, and reduced administrative costs. In combination antimicrobial therapy, the desired outcome is to extend the antimicrobial spectrum and to achieve a possible synergistic effect. However, adverse antagonistic species may sometimes emerge from such combinations, leading to treatment failure. Therefore, it is crucial to screen the drug candidates for compatibility and possible antagonistic interactions. This work aims to develop a novel synergistic dry powder inhaler (DPI) formulation for antimicrobial combination therapy via the pulmonary route. Binary and ternary combinations were prepared via spray drying on a BUCHI® Nano Spray Dryer B-90. All powders were within the respirable size range, and were consisted of spherical particles that were slightly corrugated. The powers yielded fine particle fractions (of the loaded dose) of over 40% when dispersed using an Aerolizer® DPI at 60 L/min. Time-kill studies carried out against common respiratory tract pathogenic bacteria Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumonia and Acinetobacter baumannii at 1x the minimum inhibitory concentration (MIC) over 24 hours revealed no antagonistic behavior for both combinations. While the interactions were generally found to be indifferent, a favorable synergistic effect was detected in the binary combination when it was tested against Pseudomonas aeruginosa bacteria.

    Full Text Available Abstract Polyarticular juvenile idiopathic arthritis (JIA is a category of JIA where multiple joints are affected by chronic inflammation, and where serious and lasting damage to joints is the expected natural history in untreated disease. There is evidence of response to disease-modifying antirheumatic and biologic drugs, but little evidence of permanent remission from any of the existing therapeutic trials. The TREAT trial by Wallace et al., recently published in Arthritis and Rheumatism, used a collaborative multicenter approach to studying early aggressive treatment of polyarticular JIA in an attempt to achieve full clinical inactive disease after 6 months of treatment. The study's main finding that the earlier in the disease course that treatment is started, the better the chance of disease control, has provided evidence that there is a 'window of opportunity' for treating JIA as there is in adult rheumatoid arthritis (RA. The study provides both a platform and an impetus for concentrating future treatment trials on early rather than established disease and investigating a standard of starting treatment within 10 to 12 weeks.

    It is accepted that combination DMARD therapy is a useful tool in current rheumatological practice. However, well-designed, large, long-term, controlled clinical trials are needed to determine which combinations, dosage schedules, and sequences of administration are most beneficial and least toxic. Until we develop treatment regimens that reliably induce and sustain acceptable control of disease manifestations in all patients for the rest of their natural lifespan, daily oral prednisone will continue to be a troublesome component of 'bridge' therapy, as it becomes the sole surviving constant in complex regimens whose other components are eventually discontinued because of toxicity, lack of efficacy, or non-compliance. We have often seen patients in whom the replacement of a well-tolerated but presumable ineffective DMARD with another DMARD has led to worsening of disease, when the modest benefits of the discontinued DMARD were lost before the hoped for onset of benefit from its replacement became evident. Since the toxicity of combinations of DMARDs has not appeared to be excessive, one can reasonably add the second DMARD to the first, while carefully monitoring for adverse effects and planning ton continue the combination until increased benefit occurs. Subsequently, if the second DMARD is not tolerated, the partial benefit from the first has not been given up, and a longer duration of treatment with the initial DMARD is sometimes associated with satisfactory improvement. If better control of rheumatoid arthritis is evident after 3-6 months of treatment with the combination of DMARDs, one must still decide whether to stop the first DMARD, stop the second, or continue with the combination. In the absence of major toxicity, we are most likely to choose to continue the combination if the patient has had a good response, thus inadvertently embarking on prolonged combined DMARD therapy (Paulus, 1990). Of course, other drugs besides those discussed above are available

  6. Combinational chelation therapy abrogates lead-induced neurodegeneration in rats

    International Nuclear Information System (INIS)

    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.

  7. Optimal therapy for chronic hepatitis B: hepatitis B virus combination therapy?

    2015-01-01

    Currently available antiviral treatment for chronic hepatitis B can be divided into two classes of therapeutic agents: pegylated interferon alpha (PEG-IFN) and nucleos(t)ide analogues (NAs). The major advantages of NAs are good tolerance and potent antiviral activity associated with high rates of on-treatment response to therapy. The advantages of PEG-IFN include a finite course of treatment, the absence of drug resistance, and an opportunity to obtain a durable post-treatment response to therapy. The use of these two antiviral agents with different mechanisms of action in combination is theoretically an attractive approach for treatment, either simultaneously, as sequential combination therapy (add-on), or even as an immediate switch from one agent to the other. Different NAs have also been combined in certain clinical situations. At present, several studies have confirmed certain virological advantages to combination therapies, but pivotal prospective studies demonstrating long-term clinical benefit to patients are still missing. Therefore, combination treatment, especially with PEG-IFN plus NAs, is not indicated and was not recommended by the European Association for the Study of the Liver Clinical Practice Guidelines written in 2012, while the guidelines for the use of combination NAs is limited to very few clinical situations.

    Perianal fistulas are the most common and frequently encountered types of fistulas in Crohn's disease (CD). They are incurable, may worsen quality of life in a patient and increase the risk of total bowel resection. Despite the significant impact of biological (anticytokine) therapy for fistular CD, treatment in this category of patients remains a difficult task with the high risk of recurrent CD. Mesenchymal stromal cells (MSCs) having immunomodulatory properties and a great regenerative potential are currently also used to treat fistulas in CD and perianal fistulas of another etiology. The given clinical case demonstrates that complete fistula healing could be achieved only after a few local administrations of MSCs in combination with infliximab and azathioprine. World and our experiences indicate that there is a need for randomized controlled trials with a sufficient number of patients to prove the efficacy of MSCs in the combination therapy of fistulas in CD.

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

    International Nuclear Information System (INIS)

    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

    2012-07-01

    Intraocular pressure (IOP) reduction is currently the only therapeutic approach demonstrated to preserve visual function in patients with glaucoma. The first line of glaucoma treatment consists of topical IOP-lowering medications, usually initiated as monotherapy. A significant proportion of patients require more than one medication to reach a target IOP at which optic nerve damage will not progress. As prostaglandin analogues (PGAs) are the most effective class for reducing IOP, one of the other commonly used classes (β-adrenoceptor antagonist [β-blocker], carbonic anhydrase inhibitor or α(2)-adrenoceptor agonist) is frequently combined with a PGA. In the last decade, the use of fixed combinations containing two medications in a single bottle has steadily increased. Fixed combinations have the potential to simplify the dosing regimen, increase patient adherence, avoid the washout effect of the second drop on the first medication instilled, decrease exposure to preservatives and, sometimes, reduce the cost of treatment. Clinical trials have evaluated PGA-based fixed combinations versus unfixed combinations (individual components administered concomitantly) or versus individual monotherapies; however, any advantage that the fixed combinations may have in terms of IOP-lowering efficacy is still debated. For these reasons, the PGA-based fixed combinations are not approved by regulatory authorities in some countries, such as the US. We review the published studies evaluating the efficacy and tolerability of the IOP-lowering unfixed and fixed combination therapies with PGAs. Regarding unfixed combinations, the review shows that α(2)-adrenergic agonists-PGA and carbonic anhydrase inhibitor-PGA combinations seem to be at least as effective at reducing IOP as the β-blocker-PGA combinations. As for the fixed combinations, the review shows that the three PGA-timolol fixed combinations are more effective than their component medications used separately as monotherapy and

    Benign prostatic hyperplasia (BPH) is a highly prevalent condition of older men caused by unregulated growth of the prostate gland. Clinical trials of medical therapy for BPH have consistently demonstrated that combined therapy with an α(1)-adrenergic receptor (AR) antagonist and a 5α-reductase inhibitor is superior to either agent alone. The addition of anticholinergic therapy to a treatment regimen could effectively improve symptoms in men with persistent storage lower urinary tract symptoms (LUTS) who have not seen a benefit with an α(1)-AR antagonist or 5α-reductase inhibitor. Among α(1)-AR antagonists, doxazosin, terazosin, tamsulosin, and alfuzosin, although with slight differences in adverse event profiles, are equivalent in effectiveness and efficacy. No data in the form of direct comparator trials exist to suggest a difference in clinical efficacy of finasteride and dutasteride, the two 5α-reductase inhibitors currently available. Current American Urological Association guidelines do not recommend phytotherapy or dietary supplements in any combination for the medical management of BPH. The current literature supports the safety and efficacy of the combination of an α(1)-AR antagonist and a 5α-reductase inhibitor in the treatment of symptomatic BPH and, in select patients, the use of an α(1)-AR antagonist and anticholinergic medication in the treatment of LUTS suggestive of BPH.

    Treatment for pulmonary arterial hypertension (PAH) has been underpinned by single-agent therapy to which concomitant drugs are added sequentially when pre-defined treatment goals are not met.This retrospective analysis of real-world clinical data in 97 patients with newly diagnosed PAH (86% in New York Heart Association functional class III-IV) explored initial dual oral combination treatment with bosentan plus sildenafil (n=61), bosentan plus tadalafil (n=17), ambrisentan plus tadalafil (n=11) or ambrisentan plus sildenafil (n=8).All regimens were associated with significant improvements in functional class, exercise capacity, dyspnoea and haemodynamic indices after 4 months of therapy. Over a median follow-up period of 30 months, 75 (82%) patients were still alive, 53 (71%) of whom received only dual oral combination therapy. Overall survival rates were 97%, 94% and 83% at 1, 2 and 3 years, respectively, and 96%, 94% and 84%, respectively, for the patients with idiopathic PAH, heritable PAH and anorexigen-induced PAH. Expected survival rates calculated from the French equation for the latter were 86%, 75% and 66% at 1, 2 and 3 years, respectively.Initial combination of oral PAH-targeted medications may offer clinical benefits, especially in PAH patients with severe haemodynamic impairment.

  17. An evaluation of the efficacy and toxicity of the MACOP-B regimen alone and in combination with radiotherapy for advanced, aggressive non-Hodgkin's lymphoma

    International Nuclear Information System (INIS)

    24 patients with clinically advanced and histologically aggressive non-Hodgkin's lymphoma received MACOP-B chemotherapy. 18 patients completed the full course of chemotherapy, 9 patients also received consolidation limited-field radiation therapy. Twelve out of 18 eligible patients (66.7%) achieved a complete remission (CR) after chemotherapy, and further 2 patients achieved a subsequent CR after consolidation therapy. Total CR rate was 77.8%. The absolute 3-year survival rate was 33.3% in the group of all 24 patients treated. The results confirm the effectiveness of the MACOP-B regimen for patients with advanced, aggressive non-Hodgkin's lymphoma. MACOP-B is however toxic, and should be modified, especially for patients older than 60 years of age. (author)

The FDA website, as well as manufacturer prescribing information, was also reviewed to identify other relevant information.Results: Azilsartan is a new ARB with high affinity for the angiotensin 1 receptor, approved by the FDA for hypertension management. Unlike other ARBs, azilsartan has no clinical data supporting improvement in cardiovascular outcomes, and is not approved for indications other than hypertension, which a select few other ARBs may be used for (eg, diabetic nephropathy and heart failure. Chlorthalidone is a longer acting thiazide-like diuretic that has been demonstrated to improve cardiovascular outcomes. Combination treatment with azilsartan/chlorthalidone is effective for reducing blood pressure. Compared to olmesartan/hydrochlorothiazide and azilsartan/hydrochlorothiazide combinations, azilsartan/chlorthalidone appears to be more efficacious for reducing blood pressure.Conclusions: Azilsartan/chlorthalidone can be considered an antihypertensive therapy option in patients for whom combination therapy is required (blood pressure >20 mmHg systolic or

    Highlights: ► p38 and Akt are the crucial molecular targets in the pathogenesis of SCCs in OTRs. ► Combined inhibition of these targets diminished tumor growth by 90%. ► Inhibition of these targets act through downregulating mTOR signaling pathway. -- Abstract: Non-melanoma skin cancers (NMSCs) are the most common neoplasm in organ transplant recipients (OTRs). These cancers are more invasive and metastatic as compared to those developed in normal cohorts. Previously, we have shown that immunosuppressive drug, cyclosporine A (CsA) directly alters tumor phenotype of cutaneous squamous cell carcinomas (SCCs) by activating TGF-β and TAK1/TAB1 signaling pathways. Here, we identified novel molecular targets for the therapeutic intervention of these SCCs. We observed that combined blockade of Akt and p38 kinases-dependent signaling pathways in CsA-promoted human epidermoid carcinoma A431 xenograft tumors abrogated their growth by more than 90%. This diminution in tumor growth was accompanied by a significant decrease in proliferation and an increase in apoptosis. The residual tumors following the combined treatment with Akt inhibitor triciribine and p38 inhibitors SB-203580 showed significantly diminished expression of phosphorylated Akt and p38 and these tumors were less invasive and highly differentiated. Diminished tumor invasiveness was associated with the reduced epithelial–mesenchymal transition as ascertained by the enhanced E-cadherin and reduced vimentin and N-cadherin expression. Consistently, these tumors also manifested reduced MMP-2/9. The decreased p-Akt expression was accompanied by a significant reduction in p-mTOR. These data provide first important combinatorial pharmacological approach to block the pathogenesis of CsA-induced highly aggressive cutaneous neoplasm in OTRs.

    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. PMID:15585110

    Full Text Available Diabetes mellitus (DM is a spectrum of metabolic disorder characterized by chronic hyperglycemia either due to an absolute or a relative insulin deficiency. The prevalence of diabetes varies between various countries and ethnic groups and of late, it has reached epidemic proportions in both the developed as well as in the developing countries. There is an intense need for new and effective therapies for Type 2 DM (T2DM with improved safety and tolerability profiles to reduce the outcome of the acute and chronic complications of this condition. Empagliflozin is a new class of selective sodium glucose cotransporter-2 inhibitor approved for the treatment of T2DM in 2014. It has a novel and a unique mechanism of action in that it inhibits the reabsorption of glucose in the kidneys, promotes excessive glucose excretion through a non-insulin dependent mechanism and induces glycosuria. Metformin is the only biguanide which is currently the widely accepted first-line drug for T2DM. It is effective as monotherapy and as combination therapy and has proven beneficial effects on microvascular and macrovascular complications of DM. Recently, the US Food and Drug Administration has approved the fixed dose combination of empagliflozin with metformin hydrochloride during August 2015. The combination of empagliflozin/metformin hydrochloride can be used as an adjunctive therapy to diet and exercise in patients those who are not adequately controlled with monotherapy of either empagliflozin or metformin. This drug update focuses on the insulin-independent unique mechanism of action of empagliflozin and its beneficial effects alone and in combination with metformin in patients with T2DM.

    Hypertensive cardiomyopathy is a common complication of hypertension, with a prevalence ranging from 12% to 26%. It is associated with an increased cardiac mortality and morbidity. Lifestyle changes and antihypertensive therapy usually have a significant, but relatively small effect on left ventricular hypertrophy (LVH), which is associated with a reduction in cardiovascular risk. In this paper, we describe a 39-year-old woman with severe LVH. On transthoracic echocardiogram there was concentric LVH, systolic function was a mildly reduced and there was diastolic dysfunction grade III. After only 6 months of therapy with a combination of antihypertensive agents, the left ventricular mass index was reduced by 29%, systolic function was normal and the diastolic dysfunction improved to grade I. This paper shows that in hypertensive cardiomyopathy, even severe LVH can be completely reversible. PMID:27060071

  5. New and emerging combination therapies for esophageal cancer

    International Nuclear Information System (INIS)

    Esophageal cancer comprises two different histological forms – squamous cell carcinoma (SCC) and adenocarcinoma (AC). While the incidence of AC has increased steeply in Western countries during the last few years, the incidence of SCC is fairly stable. Both forms differ in pathogenesis and response to chemotherapy and radiation therapy. Plenty of studies have evaluated new chemotherapy combination regimens in the neoadjuvant, adjuvant, and palliative setting. In addition, new radiation and chemoradiation protocols have been investigated. Finally, molecular-targeted therapy has been included in several new randomized prospective trials. Therefore, this review presents new data on this topic and critically discusses promising approaches towards a more effective treatment in a disease with a grim prognosis

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

    Full Text Available Background. Calcific uremic arteriolopathy (CUA or calciphylaxis though generally noted for its high mortality, recent case reports have shown promising results using single agent therapies. However, it is not clear whether combination therapeutic agents will improve course of the disease. Objective. To determine clinical outcome in subjects with CUA on multimodal treatment. Methods. All patients with end-stage renal failure (ESRF at The Townsville Hospital, Australia, from April 1, 2006, to March 31, 2011, with diagnosis of CUA were retrospectively studied. Results. Six subjects with CUA (4 females and 2 males were on various combination therapeutic agents comprising sodium thiosulphate, hyperbaric oxygen, prednisolone, cinacalcet, and parathyroidectomy in addition to intensified haemodialysis, specialist local wound care, and antibiotics. The wounds failed to heal in 3 patients while 5 of the 6 subjects died; cause of death being sepsis in 3 and myocardial infarction in 2. Conclusion. Prognosis of CUA remains poor in spite of multimodal combination therapy. Further prospective studies on a larger population are needed to verify our findings.

  8. Combination of photodynamic therapy and immunotherapy - evolving role in dermatology

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

  9. Biological basis of combination therapy with radiation and bleomycin

    International Nuclear Information System (INIS)

    The biological basis for combination therapy with radiation and bleomycin (BLM) was studied on C2W 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 C2W cells were irradiated, incubated at 370C 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.)

    Introduction Aggressive periodontitis comprises a group of rare, severe, rapidly progressive form of periodontitis. Conventional treatment includes mechanical debridement augmented with adjunctive antimicrobial therapy. Development of antibiotic resistance has led to use of lasers. Photodynamic therapy (PDT) is a novel non-invasive therapeutic approach with increased site and pathogen specificity. This study compares PDT and Lasers as an adjunct to conventional Scaling in the treatment of patients with aggressive periodontitis. Materials and Methods Fifteen untreated aggressive periodo-ntitis patients were randomly assigned in a split mouth design for one of the following treatment modalities: 1) SRP alone; (2) SRP + Diode Laser irradiation with 810 nm at 1W, continuous mode for 30 sec per tooth; (3) SRP + PDT on “0” day; (4) SRP + PDT on “0”, 7th and 21st day. The clinical parameters included PI, BOP, PPD, CAL recorded at the baseline & 3rd month. The site with greatest probing pocket depth (PPD) was selected from each quadrant for bacterial sampling and cultured for Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis & Prevotella intermedia. Results Statistically significant reduction in clinical & microbial parameters was seen. Sites 4 showed a greater reduction compared to other groups. Conclusion Photodynamic therapy is a valuable treatment modality adjunctive to conventional scaling and root planing. PMID:27042576

    2006-08-01

    Many medications are available for the management of acne. The armamentarium includes topical retinoids (ie, adapalene, tazarotene, tretinoin), antimicrobial and antibacterial agents (ie, benzoyl peroxide, clindamycin, erythromycin, sulfacetamide with or without sulfur), oral antibiotics (ie, doxycycline, minocycline, tetracycline), hormonal agents (ie, oral contraceptives, spironolactone), and systemic retinoids (ie, isotretinoin). Acne usually is treated with combination therapy to address its multifactorial pathophysiology. The combination of clindamycin 1%-benzoyl peroxide 5% gel, available as a stable formulation in a single tube, is efficacious and well-tolerated. The product's excipients, glycerin and dimethicone, minimize treatment-related irritation, thereby increasing patient compliance. Clindamycin-benzoyl peroxide may be well-tolerated when applied with topical retinoids, creating a more targeted and complete treatment strategy. PMID:17966494

    Non-melanoma skin cancer (NMSC) is the most common form of cancer in the Caucasian population. Among NMSC types, basal cell carcinoma (BCC) has the highest incidence and squamous cell carcinoma (SCC) is less common although it can metastasize, accounting for the majority of NMSC-related deaths. Treatment options for NMSC include both surgical and non-surgical modalities. Even though surgical approaches are most commonly used to treat these lesions, Photodynamic Therapy (PDT) has the advantage of being a non-invasive option, and capable of field treatment, providing optimum cosmetic outcomes. Numerous clinical research studies have shown the efficacy of PDT for treating pre-malignant and malignant NMSC. However, resistant or recurrent tumors appear and sometimes become more aggressive. In this sense, the enhancement of PDT effectiveness by combining it with other therapeutic modalities has become an interesting field in NMSC research. Depending on the characteristics and the type of tumor, PDT can be applied in combination with immunomodulatory (Imiquimod) and chemotherapeutic (5-fluorouracil, methotrexate, diclofenac, or ingenol mebutate) agents, inhibitors of some molecules implicated in the carcinogenic process (COX2 or MAPK), surgical techniques, or even radiotherapy. These new strategies open the way to a wider improvement of the prevention and eradication of skin cancer. PMID:26516853

    After surgical excision adjuvant therapy of desmoid tumors is necessary in such cases, where a radical excision with a wide margin is not possible, or must be doubted or after the surgical excision of a locally recurrent tumor. Radiation doses of 50 to 60 Gy reduce the risk of local recurrence of desmoid tumors to 18%. In such cases, where surgery and radiotherapy have been leading to incomplete responses, systemic therapy with hormons, with alkylating agents or with prostaglandin antagonists is possible. The published data on therapeutic responses to the treatment of desmoid tumors are scarce. We are reporting on seven of our own cases, treated with surgery and radiotherapy (four) or with a combination of surgery, radiotherapy, hormons and chemotherapy (three). (orig./MG)

    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)

    Nanocarrier-based anti-tumor drugs hold great promise for reducing side effects and improving tumor-site drug retention in the treatment of solid tumors. However, therapeutic outcomes are still limited, primarily due to a lack of drug penetration within most tumor tissues. Herein, we propose a strategy using a nanocarrier-based combination of vascular disrupting agents (VDAs) and cytotoxic drugs for solid tumor therapy. Specifically, combretastatin A-4 (CA4) serves as a "cannon" by eradicating tumor cells at a distance from blood vessels; concomitantly, doxorubicin (DOX) serves as a "pawn" by killing tumor cells in close proximity to blood vessels. This "cannon and pawn" combination strategy acts without a need to penetrate every tumor cell and is expected to eliminate all tumor cells in a solid tumor. In a murine C26 colon tumor model, this strategy proved effective in eradicating greater than 94% of tumor cells and efficiently inhibited tumor growth with a weekly injection. In large solid tumor models (C26 and 4T1 tumors with volumes of approximately 250 mm(3)), this strategy also proved effective for inhibiting tumor growth. These results showing remarkable inhibition of tumor growth provide a valuable therapeutic choice for solid tumor therapy. PMID:27217835

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

    For patients with sarcoma, metastatic disease remains very difficult to cure, and outcomes remain less than optimal. Treatment options have not largely changed, although some promising gains have been made with single agents in specific subtypes with the use of targeted agents. Here, we developed a system to investigate synergy of combinations of targeted and cytotoxic agents in a panel of sarcoma cell lines. Agents were investigated alone and in combination with varying dose ratios. Dose-response curves were analyzed for synergy using methods derived from Chou and Talalay (1984). A promising combination, dasatinib and triciribine, was explored in a murine model using the A673 cell line, and tumors were evaluated by MRI and histology for therapy effect. We found that histone deacetylase inhibitors were synergistic with etoposide, dasatinib, and Akt inhibitors across cell lines. Sorafenib and topotecan demonstrated a mixed response. Our systematic drug screening method allowed us to screen a large number of combinations of sarcoma agents. This method can be easily modified to accommodate other cell line models, and confirmatory assays, such as animal experiments, can provide excellent preclinical data to inform clinical trials for these rare malignancies.

  3. Therapeutic Cancer Vaccines in Combination with Conventional Therapy

    Mads Hald Andersen

    2010-01-01

    Full Text Available The clinical efficacy of most therapeutic vaccines against cancer has not yet met its promise. Data are emerging that strongly support the notion that combining immunotherapy with conventional therapies, for example, radiation and chemotherapy may improve efficacy. In particular combination with chemotherapy may lead to improved clinical efficacy by clearing suppressor cells, reboot of the immune system, by rendering tumor cells more susceptible to immune mediated killing, or by activation of cells of the immune system. In addition, a range of tumor antigens have been characterized to allow targeting of proteins coupled to intrinsic properties of cancer cells. For example, proteins associated with drug resistance can be targeted, and form ideal target structures for use in combination with chemotherapy for killing of surviving drug resistant cancer cells. Proteins associated with the malignant phenotype can be targeted to specifically target cancer cells, but proteins targeted by immunotherapy may also simultaneously target cancer cells as well as suppressive cells in the tumor stroma.

    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. PMID:15900815

  9. Combination radiation therapy for bone metastases in thyroid cancer

    International Nuclear Information System (INIS)

    sentinel and distant lymph nodes. The presence of bone metastases was revealed using x-ray study and confirmed using bone scan with Tc-99m pyrophosphate. During the treatment the patients with bone metastases were administered 1480-14,134 MBq of I-131. Of all patients with bone metastases, bone metastases accumulated I-131 only in 4 (19%) patients. Thus, treatment of TC with bone metastases only with I-131 did not produce a desirable palliative effect as well as did not control the progress of metastasizing. Therefore, together with I-131 treatment the patients received P-32 (sodium phosphate) treatment. P-32 treatment was started not earlier then 4 months after treatment with I-131. P-32 was administered orally in 100 ml of 10% glucose solution on an empty stomach, 74-120 MBq pert treatment with 4-7- day intervals. Total P-32 activity during one course of treatment made up 296-444 Mbq. Combination radionuclide therapy with I-131 sodium iodide and P-32 sodium phosphate was given to 4 patients with papillary and follicular TC with bone metastases which did not accumulate I-131. Two of these patients had diffuse metastases to the lung parenchyma. The patients received 305-369 MBq of P-32. The radiation load on the red bone marrow was 1098-1328.4 mSv at oral P-32 administration that on the body was 823.5-996.3 mSv. The signs of myelosuppression were not observed during the stay at the Institute. One patient had insignificant reduction of thrombocyte level up to 91.0 x 109 /l and leukocyte level to 2,4 o-tilde 109/l 2 month after the treatment. Three months after systemic radionuclide therapy the signs of inconsiderable myelosuppression disappeared. Pain syndrome disappeared 5-12 days after combination systemic radionuclide therapy, and the patients were able to care for themselves. Flare phenomenon was not seen. A positive feature of combination radionuclide therapy with I-131 sodium iodide and P-32 sodium phosphate together with treatment of bone metastases is possibility

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

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

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

  14. Combined radio- and hormone therapy of the prostate carcinoma

    International Nuclear Information System (INIS)

    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)

    Single drug therapy that leads to the multidrug resistance of cancer cells and severe side-effect is a thing of the past. Combination therapies that affect multiple signaling pathways have been the focus of recent active research. Due to the successful development of prodrug-based nano-drug delivery systems (P-N-DDSs), their use has been extended to combination therapy as drug delivery platforms. In this review, we focus specifically on the P-N-DDSs in the field of combination therapy including the combinations of prodrugs with different chemotherapeutic agents, other therapeutic agents, nucleic acid or the combination of different types of therapy (e.g. chemotherapy and phototherapy). The relevant examples of prodrug-based nanoparticulate drug delivery strategy in combination cancer therapy from the recent literature are discussed to demonstrate the feasibilities of relevant technology.

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

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

  1. Results of combined therapy for maxillary sinus squamous cell carcinoma

    International Nuclear Information System (INIS)

    The results of 54 cases of maxillary sinus squamous cell carcinoma treated between 1980 and 2002 were analyzed retrospectively. The T classification according to the 1997 Union Internationale Contre le Cancer (UICC) was as follows: 2 with stage T1, 29 with T3, and 23 with T4. Ten patients (18.5 %) had lymph node metastases at diagnosis. All patients underwent combined therapy including radiotherapy, surgery, and regional or systemic chemotherapy. Fifteen patients received hyperfractionated twice-daily radiotherapy (1.2 Gy or 1.5 Gy/fraction), and the remaining 39 patients received a conventional once-daily regimen (1.5-2 Gy/fraction). The 5-year overall survival and 5-year disease-free survival for all patients were 56.0% and 46.7%, respectively. The N classification was the only significant prognostic factor for 5-year disease-free survival by univariate analysis (favoring N=0, p=0.04). There were no significant differences in other prognostic factors including gender, T classification (T1-3 vs. T4), hyperfractionated radiotherapy (yes vs. no), total dose (biological effective dose (BED): 10 vs. ≥69 Gy10), and intra-arterial chemotherapy (yes vs. no). Although radiation-induced cataract was observed in 9 patients, no other severe late complications developed. (author)

    An increasing number of older patients are suffering from aggressive lymphoma. Effective and more tolerable treatment regimens are urgently needed for this growing patient population. Patients with aggressive lymphoma not eligible for anthracycline-based first-line therapy or intensive salvage regimens were treated with the rituximab-bendamustine-lenalidomide (R-BL) regimen (rituximab 375 mg/m(2)  day 1, bendamustine 70 mg/m(2)  d 1, 2, lenalidomide 10 mg d 1-21) for six cycles every 4 weeks. Forty-one patients with a median age of 75 (range 40-94) years were enrolled: 33 patients had substantial co-morbidities. 13 patients were not eligible for anthracycline-based first-line chemotherapy, 28 patients had relapsed/refractory disease. The primary endpoint, overall response, was achieved by 25 (61%) patients (95% confidence interval 45-76%). Grade ≥ 3 toxicity comprised haematological (59%), skin (15%), constitutional (15%) and neurological (12%) events. 9 patients died during trial treatment: 5 from lymphoma progression, 2 from toxicity, 2 with sudden death. After a median follow-up of 25·9 (interquartile range 20·4-31·6) months, 13 patients were still alive. Median overall survival was 14·5 months. In conclusion, R-BL can be considered a treatment option for elderly patients with treatment naïve or relapsed/refractory aggressive lymphoma not eligible for standard aggressive regimens.

  3. Aggressive local treatment containing intraoperative radiation therapy (IORT) for patients with isolated local recurrences of pancreatic cancer: a retrospective analysis

    International Nuclear Information System (INIS)

    To evaluate the use of intraoperative radiation therapy (IORT) in the multimodality treatment of patients with isolated local recurrences of pancreatic cancer. We retrospectively analyzed 36 patients with isolated local recurrences of pancreatic cancer who have been treated with a combination of surgery, IORT and EBRT. Median time from initial treatment to recurrence was 20 months. All patients were surgically explored. In 18 patients a gross total resection was achieved, whereas the other half received only debulking or no resection at all. All patients received IORT with a median dose of 15 Gy. Additional EBRT was applied to 31 patients with a median dose of 45 Gy, combined with concurrent, mainly gemcitabine-based chemotherapy. Median follow-up in surviving patients was 23 months. Local progression was found in 6 patients after a median time of 17 months, resulting in estimated 1- and 2-year local control rates of 91% and 67%, respectively. Distant failure was observed in 23 patients, mainly in liver or peritoneal space. The median estimated progression-free survival was 9 months with 1- and 2-year rates of 40% and 26%, respectively. We found an encouraging estimated median overall survival of 19 months, transferring into 1- and 2-year rates of 66% and 45%. Notably 6 of 36 patients (17%) lived for more than 3 years. Severe postoperative complications were found in 3 and chemoradiation-related grade III toxicity in 6 patients. No severe IORT related toxicity was observed. Combination of surgery, IORT and EBRT in patients with isolated local recurrences of pancreatic cancer resulted in encouraging local control and overall survival in our cohort with acceptable toxicity. Our approach seems to be superior to palliative chemotherapy or chemoradiation alone and should be further investigated in a prospective setting specifically addressing isolated local recurrences of pancreatic cancer

    2015-02-01

    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.

  10. Cancer therapy improvement with mesoporous silica nanoparticles combining photodynamic and photothermal therapy

    International Nuclear Information System (INIS)

    In this work, we develop novel mesoporous silica composite nanoparticles (hm-SiO2(AlC4Pc)@Pd) for the co-delivery of photosensitizer (PS) tetra-substituted carboxyl aluminum phthalocyanine (AlC4Pc) and small Pd nanosheets as a potential dual carrier system to combine photodynamic therapy (PDT) with photothermal therapy (PTT). In the nanocomposite, PS AlC4Pc was covalently conjugated to a mesoporous silica network, and small Pd nanosheets were coated onto the surface of mesoporous silica by both coordination and electrostatic interaction. Since small Pd nanosheets and AlC4Pc display matched maximum absorptions in the 600–800 nm near-infrared (NIR) region, the fabricated hm-SiO2(AlC4Pc)@Pd nanocomposites can generate both singlet oxygen and heat upon 660 nm single continuous wavelength (CW) laser irradiation. In vitro results indicated that the cell-killing efficacy by simultaneous PDT/PTT treatment using hm-SiO2(AlC4Pc)@Pd was higher than PDT or PTT treatment alone after exposure to a 660 nm CW-NIR laser.

    We have tested a very aggressive combination protocol with cisplatin and escalated paclitaxel in combination with accelerated hyperfractionated radiotherapy to assess the maximum tolerated dose (MTD), dose-limiting toxicity (DLT), overall toxicity, and response rate. Patients and Methods: The trial recruited 24 patients (21 males, three females, mean age 57 years) treated at our department from 1998 through 2001. Irradiation was administered in daily doses of 2 Gy up to 30 Gy followed by 1.4 Gy twice daily up to 70.6 Gy to the primary tumor and involved nodes and 51 Gy to the clinically negative regional nodes. The chemotherapy schedule included cisplatin in a fixed dose of 20 mg/m{sup 2} on days 1-5 and 29-33 and paclitaxel at increasing dose levels of 20, 25, 30 mg/m{sup 2} twice weekly over the whole treatment time. Patients were recruited in cohorts of three to six, and the MTD was reached if two out of six patients in one cohort developed DLT. DLT was defined as any grade 4 toxicity or any grade 3 toxicity requiring treatment interruption or unplanned hospitalization or any grade 3 neurotoxicity. We recruited mainly patients with large tumors for this protocol; all patients were stage IV, and the mean tumor volume (primary + metastases) amounted to 72 {+-} 61 cm{sup 3}. The mean follow-up was 30 months (range 4-39 months). Results: One early death (peritonitis and sepsis a t day 10) occurred, and 23 patients were evaluable for acute toxicity and response. The MTD of paclitaxel was reached at the third dose level (30 mg/m{sup 2} paclitaxel twice weekly). The DLT was severe mucositis grade 3 (n = 1) and skin erythema grade 4 (n = 2). After determining the MTD, another 14 patients were treated at the recommended dose level of paclitaxel with 25 mg/m{sup 2} twice weekly. In summary, 13/23 patients (57%) developed grade 3 and 10/23 (43%) grade 2 mucositis. Two patients (9%) had grade 4, five (22%) grade 3, and 16 (69%) grade 2 dermatitis. One patient died at day 30

  12. Effect of Polycosanol, a grape seed extract and its combined therapy on oxidation markers in rats

    International Nuclear Information System (INIS)

    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

    Functional imaging by 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) is being increasingly incorporated into the evaluation of patients with aggressive non-Hodgkin lymphoma (NHL). Its use for the initial staging in combination with computed tomography has now become standard. PET has recently been included in consensus criteria for response after therapy for Hodgkin lymphoma and aggressive NHL. At the end of therapy, PET has a high positive and negative predictive value (PP...

  16. Impact of combined clenbuterol and metoprolol therapy on reverse remodelling during mechanical unloading.

    Full Text Available Clenbuterol (Cl, a β2 agonist, is associated with enhanced myocardial recovery during left ventricular assist device (LVAD support, and exerts beneficial remodelling effects during mechanical unloading (MU in rodent heart failure (HF. However, the specific effects of combined Cl+β1 blockade during MU are unknown.We studied the chronic effects (4 weeks of β2-adrenoceptor (AR stimulation via Cl (2 mg/kg/day alone, and in combination with β1-AR blockade using metoprolol ((Met, 250 mg/kg/day, on whole heart/cell structure, function and excitation-contraction (EC coupling in failing (induced by left coronary artery (LCA ligation, and unloaded (induced by heterotopic abdominal heart transplantation (HATx failing rat hearts. Combined Cl+Met therapy displayed favourable effects in HF: Met enhanced Cl's improvement in ejection fraction (EF whilst preventing Cl-induced hypertrophy and tachycardia. During MU combined therapy was less beneficial than either mono-therapy. Met, not Cl, prevented MU-induced myocardial atrophy, with increased atrophy occurring during combined therapy. MU-induced recovery of Ca2+ transient amplitude, speed of Ca2+ release and sarcoplasmic reticulum Ca2+ content was enhanced equally by Cl or Met mono-therapy, but these benefits, together with Cl's enhancement of sarcomeric contraction speed, and MU-induced recovery of Ca2+ spark frequency, disappeared during combined therapy.Combined Cl+Met therapy shows superior functional effects to mono-therapy in rodent HF, but appears inferior to either mono-therapy in enhancing MU-induced recovery of EC coupling. These results suggest that combined β2-AR simulation +β1-AR blockade therapy is likely to be a safe and beneficial therapeutic HF strategy, but is not as effective as mono-therapy in enhancing myocardial recovery during LVAD support.

  17. Treatment considerations for inflammatory acne: clinical evidence for adapalene 0.1% in combination therapies.

    Acne vulgaris is an exceptionally common, chronic, and recurring disease. It involves multiple etiological factors including follicular hyperkeratinization, increased sebum production, Propionibacterium acnes proliferation, and inflammation. Presently, oral isotretinoin is the only single agent that is effective against all 4 major pathophysiologic features. However, this drug is also responsible for several serious side effects, including teratogenicity. Therefore, it should be used in only the most severe cases and alternative treatment approaches for inflammatory acne, such as initial combination therapy, should be considered first. Combination therapy in inflammatory acne simultaneously targets multiple pathogenic factors. Current guidelines recommend early initiation of combination therapy with a topical retinoid and antimicrobials for mild to moderate inflammatory acne and topical retinoids with oral antibiotics (with or without the use of benzoyl peroxide) for moderate to severe cases of acne, followed by maintenance therapy with topical retinoids. This review evaluates the rationale and clinical evidence for the use of adapalene in combination therapy for inflammatory acne. PMID:16989194

    Interstitial lung disease is an important cause of mortality and morbidity in patients with systemic sclerosis (SSc). There are currently no recommended guidelines for management of these patients. This is probably due to the rarity of this condition, as well as clinical trials with only a small number of cases. There are published case report and case series along with the two main trials, viz. Scleroderma Lung Study and the Fibrosing Alveolitis Study, but again, there is no consensus on treatment protocols. In this report, we present a case of aggressive interstitial lung disease in a patient with SSc, which improved dramatically on treatment with intra-venous cyclophosphamide and high dose prednisolone therapy.

    Waldenstrom's macroglobulinemia is generally treated with alkylating agents, purine analogs and monoclonal antibodies, alone or in combination. We report the outcomes of 82 patients (median age 61 years) treated with the RFC combination. Twenty-five patients were treatment-naive. RFC was administered every 4 weeks, for a median of five cycles. At treatment discontinuation, the overall response rate was 85.4%. The responses improved after treatment discontinuation in 25 patients, with a median time to best response achievement of 10.8 months, raising the major response rate (PR, VGPR and CR) from 64.6% to 76.8%. With a median follow-up of 47 months, the median progression-free survival time had not been reached (67% PFS at 48 months) and was influenced by age and treatment status before RFC. Likewise, the median time to next therapy had not been reached. Two cases of myelodysplastic syndrome/AML and 3 cases of transformation to aggressive lymphoma occurred. Thirteen patients died. The 3-year overall survival rate was 90%. Long-lasting cytopenias occurred in 19 patients. The RFC combination thus gave a high response rate and durable responses, even in heavily treatment-experienced patients. The high incidence of long-lasting cytopenia might be reduced by giving fewer courses and thereby minimizing myelotoxicity. Am. J. Hematol. 91:782-786, 2016. © 2016 Wiley Periodicals, Inc.

  20. Treatment of non-Hodgkin's lymphoma of Waldeyer's ring: radiotherapy versus chemotherapy versus combined therapy

    International Nuclear Information System (INIS)

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

    2013-02-01

    A combination of antiglaucoma medications is indicated if monotherapy is not sufficient to achieve the predefined target pressure and/or in case of a progression of glaucomatous damage or conversion from ocular hypertension to glaucomatous optic neuropathy. Most recently many fixed combinations with two active compounds have become available for the medical treatment of glaucoma. Compared to non-fixed combinations, these drugs offer a much easier use for the patients. Fixed combinations have to be applied less frequently which may improve adherence. Furthermore, they most likely contain a lower amount of toxic preservatives compared to non-fixed combinations. And finally, fixed combinations may eliminate the risk of a "washout" of the first medication by using the second product of a non-fixed combination too soon after the first drop has been installed. This review aims to examine the most important aspects of IOP-lowering fixed and non-fixed combinations in glaucoma management with a clear focus on the results obtained with fixed combinations. In Germany, fixed combinations with the compositions dorzolamide/timolol (FCDT), brinzolamide/timolol (FCBRINT), latanoprost/timolol (FCLT), travoprost/timolol (FCTT), bimatoprost/timolol (FCBIMT), brimonidine/timolol (FCBT), pilocarpine/timolol (FCPT) and metipranolol/timolol (FCMT) are approved for the medical management of glaucoma and ocular hypertension. The results of clinical studies comparing fixed combinations with their active ingredients and with the corresponding non-fixed combinations will be discussed. Furthermore - if available - the results of direct comparisons of the efficacy and safety of different IOP-lowering fixed combinations are summarised. PMID:23335083

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

  6. Combinations of Radiation Therapy and Immunotherapy for Melanoma: A Review of Clinical Outcomes

    International Nuclear Information System (INIS)

    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

    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.

  9. The use of combination therapy in pulmonary arterial hypertension: new developments

    2009-09-01

    Full Text Available There is a strong clinical rationale for combination therapy in pulmonary arterial hypertension (PAH, as several pathological pathways have been implicated in its pathogenesis and no single agent has yet been shown to deliver completely satisfactory results. Registry data indicate that use of combination therapy is in fact common in existing clinical practice, even though support has been largely empirical or derived from small-scale observational studies. Data from large, adequately powered, randomised controlled trials of combination therapy in PAH are now emerging and suggest that combination therapy may be clinically beneficial. Studies of bosentan in combination with prostanoids and phosphodiesterase (PDE-5 inhibitors show consistent evidence of improvements in exercise capacity compared with placebo. Similar improvements have been observed with PDE-5 inhibitors in combination with prostanoids. The appropriate timing of combination therapy requires further evaluation but goal-oriented therapy using combinations of oral and inhaled drugs has been shown to provide acceptable long-term results in patients with advanced PAH. Monitoring should be performed regularly and be based on repeatable, noninvasive, measurable parameters that have prognostic value.

    Upconversion nanoparticles (UCNPs) have drawn much attention in cancer imaging and therapy in recent years. Herein, we for the first time report the use of UCNPs with carefully engineered surface chemistry for combined photodynamic therapy (PDT) and gene therapy of cancer. In our system, positively charged NaGdF4:Yb,Er UCNPs with multilayered polymer coatings are synthesized via a layer by layer strategy, and then loaded simultaneously with Chlorin e6 (Ce6), a photosensitizing molecule, and small interfering RNA (siRNA), which targets the Plk1 oncogene. On the one hand, under excitation by a near-infrared (NIR) light at 980 nm, which shows greatly improved tissue penetration compared with visible light, cytotoxic singlet oxygen can be generated via resonance energy transfer from UCNPs to photosensitizer Ce6, while the residual upconversion luminescence is utilized for imaging. On the other hand, the silencing of Plk1 induced by siRNA delivered with UCNPs could induce significant cancer cell apoptosis. As the result of such combined photodynamic and gene therapy, a remarkably enhanced cancer cell killing effect is realized. Our work thus highlights the promise of UCNPs for imaging guided combination therapy of cancer.Upconversion nanoparticles (UCNPs) have drawn much attention in cancer imaging and therapy in recent years.

    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. Our results are in support of clinical development of heterologous adeno-/vaccinia virus therapy of cancer. PMID:27119097

    Full Text Available Abstract Background Despite aggressive multimodal treatments the overall survival of patients with high-risk neuroblastoma remains poor. The aim of this study was to identify novel combination chemotherapy to improve survival rate in patients with high-risk neuroblastoma. Methods We took a synthetic lethal approach using a siRNA library targeting 418 apoptosis-related genes and identified genes and pathways whose inhibition synergized with topotecan. Microarray analyses of cells treated with topotecan were performed to identify if the same genes or pathways were altered by the drug. An inhibitor of this pathway was used in combination with topotecan to confirm synergism by in vitro and in vivo studies. Results We found that there were nine genes whose suppression synergized with topotecan to enhance cell death, and the NF-κB signaling pathway was significantly enriched. Microarray analysis of cells treated with topotecan revealed a significant enrichment of NF-κB target genes among the differentially altered genes, suggesting that NF-κB pathway was activated in the treated cells. Combination of topotecan and known NF-κB inhibitors (NSC 676914 or bortezomib significantly reduced cell growth and induced caspase 3 activity in vitro. Furthermore, in a neuroblastoma xenograft mouse model, combined treatment of topotecan and bortezomib significantly delayed tumor formation compared to single-drug treatments. Conclusions Synthetic lethal screening provides a rational approach for selecting drugs for use in combination therapy and warrants clinical evaluation of the efficacy of the combination of topotecan and bortezomib or other NF-κB inhibitors in patients with high risk neuroblastoma.

    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.

    Full Text Available Aggressive periodontitis which is an uncommon condition is characterized by severe loss of attachment and destruction of alveolar bone around one or more permanent teeth during the period of pubescence. Aggressive periodontitis have localized and generalized forms. It is currently believed that combination of bacteriologic, immunologic and hereditary factors are of major importance in the etiology of this disease. The case was of a 14 - year old female and his clinical and radiographic findings were typical for generalized aggressive periodontitis. Treatment consisted of thorough training in techniques of plaque control, scaling and root planning and administration of tetracycline 250 mg every six hours for three weeks, as well as combined surgery and antibiotic therapy. But both failed to cure or control the disease mostly because of the non-cooperation with the oral hygiene instructions.

    Full Text Available Purpose: To evaluate the outcomes of the patients who were infected with colistin-only-susceptible (COS Acinetobacter baumannii and treated with either colistin monotherapy or colistin combined therapy. Materials and Methods: This retrospective case-control study was conducted in the training and research hospital with an 800 beds between August 2008 and December 2011. The patients, who were infected with COS A. baumannii and received either colistin monotherapy or colistin combined therapy, were included into the study. Results: In total, 51 patients fulfilling study criteria were evaluated. Colistin monotherapy was found effective as much as colistin combined therapy in terms of clinical and microbiological responses in patients with ventilator associated pneumonia (VAP and also in patients with blood stream infections. Conclusion: Although there is no randomised controlled study yet, colistin monotherapy and colistin combined therapy are likely to achieve similar treatment responses rates. Heteroresistant strains can emerge in patients who receive colistin monotherapy

    Combining controllable photothermal therapy and efficacious gene therapy in a single platform holds great promise in cancer therapy due to the enhanced combined therapeutic effects. Herein, polyethyleneimine-grafted oxidized mesoporous carbon nanospheres (OP) were developed for combined photothermal combined gene therapy in vitro and in vivo. The synthesized OP was characterized to have three dimensional spherical structure with uniformed diameter, ordered mesopores with graphitic domains, high water dispersion with zeta potential of +22 mV, and good biocompatibility. Consequently, OP was exploited as the photothermal convertor with strong NIR absorption and the gene vector via electrostatic interaction, which therefore cannot only deliver the therapeutic gene (pING4) to tumors for gene therapy, but also can eliminate the tumors by photothermal ablation. Moreover, the improved gene therapy accompanied by the NIR photothermally enhanced gene release was also well achieved based on OP. The excellent combined therapeutic effects demonstrated in vitro and in vivo suggested the OP's potential for cancer therapy. PMID:27258483

    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.

  11. Combined therapy of corpus carcinoma with special regard to radiotherapy

    International Nuclear Information System (INIS)

    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.

    Objective:To evaluate the current approaches for multimodality therapy for stage ⅠB cervical cancer. Methods:The relevant literature has served as a source for identified high or intermediate risks and management of stage ⅠB cervical cancer. Result:The high risks include pelvic lymph node metastasis (PLNM), positive resection margin (PRM), and the in-volvement of parametrium (IPM). The intermediate risks include deep stromal invasion (DSI), bulky tumor size ( BTS), lymphovascular space invasion (LVSI). Adeno-carcinomatous histo-type is the new risk feature relevant to poor prognoses. Both radical hysterectomy plus bilateral pelvic lymph node dissection(PLND) and radical radiotherapy have proven to be equally effec-tive. Surgery is more performed for stage ⅠB1 disease;radiotherapy or chemoradiotherapy is preferable for stage ⅠB2 disease. For patients with one high risk or two of intermediate risks, radical hysterectomy plus PLND followed by concurrent chemoradiotherapy can improve overall survival(OS) and disease-free survival (DFS). Conclusion:The management should be indi-vidualized for stage ⅠB cervical cancer. The optimized multidisciplinary therapy can benefit pa-tients with the best cure and minimum morbidity and complications.

    The ideal goal of chronic hepatitis B(CHB) treatment should be suppression of emergence of hepatocellular carcinoma through the disappearance of hepatitis B s antigen(HBs Ag) rather than the control of serum hepatitis B virus-DNA level. For this purpose, various types of combination therapies using nucleoside analogs(NAs) and interferon(IFN) have been conducted. The therapeutic effects of combination of two different kinds of agents are better than those of the monotherapy using NAs or IFN alone, probably because different pharmaceutical properties might act in a coordinated manner. Recently, combination therapies with NAs and IFN and sequential therapies with NAs administration followed by IFN therapy have been routinely employed. We previously reported that combination therapy using entecavir(ETV) and pegylated(PEG)-IFN showed antiviral effects in 71% of CHB patients; the effect of this combination was better than that using lamivudine(LAM) and PEG-IFN. This is partially explained by the better antiviral effects of ETV than those of LAM. In our analysis, the cohort of CHB consisted of the patients who showed a flare-up of hepatitis before antiviral therapy, and their baseline HBs Ag levels were relatively low. Therefore, in addition to the combination of the agents, the appropriate selection of patients is critical to achieve a good viral response.

    International Nuclear Information System (INIS)

    The subjects were 52 patients (5-78 years, average 51.4 years) with primary brain tumor treated in 4 institutes in Chugoku and Shikoku districts during 3 years from April 1991. Histopathologically, the subject diseases were glioblastoma in 16, well differentiated glioblastoma in 19, brain primary lymphoma in 9, and malignant meningioma in 5. In the glioblastoma group, 14 received surgery, radiotherapy, and chemotherapy at the first admission. Three patients who survived more than 1 year and 6 patients who died within 1 year were compared. No significant difference was observed in terms of radiotherapy between the both groups. In the astrocytoma and oligodendroglioma groups, 16 patients received radiotherapy and chemotherapy as the initial treatment, and 14 underwent several course of maintenance therapy. In the comparison between 7 patients who died within 3 years from the first treatment and 9 patients surviving more than 3 years, no significant difference was observed in terms of radiation doses.

    International Nuclear Information System (INIS)

    216 malignant renal tumors were postoperatively or directly irradiated. More than 80% of them were adenocarcinomas which were classified according to the UICC. The 5-year survival rates were 80% for T 1, 60% for T 2, 45% for T 3 and T x, 37.5% for T 4. Even inoperable patients still had a 4-year survival rate of 11%. Carcinomas of the renal pelvis had the same 5-year survival rate as the T 4 group. The therapeutic results of other authors are tabulated. A female patient with Wilm's tumor out of 3 cases has already survived for 7 years, though she had undergone exstirpation of an isolated liver metastasis together with cholecystectomy 4 years after starting therapy.

    Full Text Available Cervical cancer is one of the most common cancers in women worldwide, being high-risk group the HPV infected, the leading etiological factor. The raf kinase inhibitory protein (RKIP has been associated with tumor progression and metastasis in several human neoplasms, however its role on cervical cancer is unclear. In the present study, 259 uterine cervix tissues, including cervicitis, cervical intraepithelial lesions and carcinomas, were analyzed for RKIP expression by immunohistochemistry. We found that RKIP expression was significantly decreased during malignant progression, being highly expressed in non-neoplastic tissues (54% of the samples; 73/135, and expressed at low levels in the cervix invasive carcinomas (∼15% (19/124. Following in vitro downregulation of RKIP, we observed a viability and proliferative advantage of RKIP-inhibited cells over time, which was associated with an altered cell cycle distribution and higher colony number in a colony formation assay. An in vitro wound healing assay showed that RKIP abrogation is associated with increased migratory capability. RKIP downregulation was also associated with an increased vascularization of the tumors in vivo using a CAM assay. Furthermore, RKIP inhibition induced cervical cancer cells apoptotic resistance to cisplatin treatment. In conclusion, we described that RKIP protein is significantly depleted during the malignant progression of cervical tumors. Despite the lack of association with patient clinical outcome, we demonstrate, in vitro and in vivo, that loss of RKIP expression can be one of the factors that are behind the aggressiveness, malignant progression and chemotherapy resistance of cervical cancer.

Even with current targeting therapies, such as rituximab and other chemotherapeutic agents, there is a need to develop new treatment strategies. Combination therapy seems the best option to target the tumor cells by different mechanisms. Virotherapy is a very promising treatment modality, as it is selective, safe, and causes cancer destruction. The Iraqi strain of Newcastle disease virus (NDV has proved to be effective both in vitro and in vivo. In the current work, we tested its ability on anti-hematological tumors and enhanced current treatments with combination therapy, and studied this combination using Chou–Talalay analysis. p53 concentration was measured to evaluate the mechanism of this proposed synergism. The results showed that NDV was synergistic with doxorubicin in low doses on plasmacytoma cells, with no involvement of p53 pathways, but involved p53 when the combination was used on non-Hodgkin lymphoma cells. NDV in combination with rituximab showed enhanced cytotoxicity that was p53-independent. In conclusion, this work proposes a novel combination modality for treatment of some hematological malignancies.Keywords: oncolytic viruses, virotherapy, combination therapy

  4. The Clinical Development of Molecularly Targeted Agents in Combination With Radiation Therapy: A Pharmaceutical Perspective

    International Nuclear Information System (INIS)

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

    Full Text Available Ewing's sarcoma's relapse rarely occurs more than two years after the initial diagnosis. We report the case of a 26-year-old man with a history of Ewing's sarcoma of the left maxillary sinus at the age of 10 who presented with a very late local relapse, 16 years after the first occurrence of disease. Ultimate control was achieved after multimodal therapy including surgery, high-dose chemotherapy, and radiotherapy. This report indicates that local relapses of Ewing's sarcoma can be treated with curative intent in selected cases.

    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.

  11. The combination therapy with hepatic arterial infusion chemotherapy and radiation therapy for advanced intrahepatic cholangiocarcinoma

    International Nuclear Information System (INIS)

    Intrahepatic cholangiocarcinoma is rare, usually diagnosed at the considerably advanced stage and thereby difficult for surgery. For such cases, the therapy in the title is conducted in authors' hospital, of which outcome is described herein. Stage III-IVB cases of 25 patients underwent the therapy (1996-2005). Chemotherapy was by cisplatin (CDDP)+5 fluorouracil (FU), or Epirubicin (FARM)+Mitomycin C (MMC)+5FU. Radiation therapy was performed on the vascular invasion and metastatic lymphaden and if possible, on the primary site, at total 39-50 Gy in a fractionated manner, by internal irradiation at 15 Gy (2 cases), and on bone metastasis at 25 Gy (1 case). Efficacy was evaluated by the Criteria 2004 by the Liver Cancer Study Group in Japan. Evaluation 6 months after therapy was partial response (PR) in 9 cases, standard deviation (SD) in 2, progressive disease (PD) in 13, data unavailable in 1: the efficacy rate was 36% (9/25). One-year survival was 52.5%, 2-year 43.7%, and 3-year 28.1%. The predicting prognosis factor found was significantly good in female and in cases without remote metastases and/or metastatic lymphadens around aorta. Thus the therapy was valuable to try and cooperative, multi-center study was thought necessary in future. (R.T.)

    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. PMID:21883932

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

    Lanthanide-doped upconversion nanoparticles (UCNPs) have the ability to generate ultraviolet or visible emissions under continuous-wave near-infrared (NIR) excitation. Utilizing this special luminescence property, UCNPs are approved as a new generation of contrast agents in optical imaging with deep tissue-penetration ability and high signal-to-noise ratio. The integration of UCNPs with other functional moieties can endow them with highly enriched functionalities for imaging-guided cancer therapy, which makes composites based on UCNPs emerge as a new class of theranostic agents in biomedicine. Here, recent progress in combined cancer therapy using functional nanocomposites based on UCNPs is reviewed. Combined therapy referring to the co-delivery of two or more therapeutic agents or a combination of different treatments is becoming more popular in clinical treatment of cancer because it generates synergistic anti-cancer effects, reduces individual drug-related toxicity and suppresses multi-drug resistance through different mechanisms of action. Here, the recent advances of combined therapy contributed by UCNPs-based nanocomposites on two main branches are reviewed: i) photodynamic therapy and ii) chemotherapy, which are the two most widely adopted therapies of UCNPs-based composites. The future prospects and challenges in this emerging field will be also discussed. PMID:26505885

  16. Clinical Considerations for Use of Initial Combination Therapy in Type 2 Diabetes.

    2016-08-01

    Type 2 diabetes is a progressive disorder characterized by increasing hyperglycemia and the need to gradually intensify therapy in order to achieve and maintain glycemic control. Early initiation of combination therapy has been proposed as an approach to achieve glycemic goals earlier and delay the deterioration of glycemic control and with possible better preservation of β-cell function. We discuss in this article the pros and cons of this approach, focusing on individuals with HbA1c at diagnosis of 7.5-9.0%, where difference of opinion still exists on management. Initial combination therapy is proposed to lead to better and faster achievement of glycemic targets versus monotherapy and to impede clinical inertia and may possibly slow the deterioration of β-cell function. However, treating patients with sequential therapy is proposed to allow one to fully assess the efficacy and risk-to-benefit ratio of each drug as it is added. Furthermore, there is no evidence to support that rapid addition and titration of medications according to the glycemic profile achieved are inferior to initial combination therapy if glycemic targets are attained in a timely manner. Initial combination therapy is argued to postpone clinical inertia to the next decision point but does not eliminate it. Additionally, it may have been the agents chosen and not the timing of their initiation that led to improved β-cell function in the studies of initial combination therapy, and there are no data currently comparing use of the same drugs initiated simultaneously or sequentially. Heightened awareness of providers, individualization of therapy and setting, and reaching glycemic targets remain the mainstays of care. PMID:27440826

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

  18. Single-pill triple-combination therapy: an alternative to multiple-drug treatment of hypertension.

    Hypertension (HTN) affects an estimated 76.4 million US adults. Despite improvements in blood pressure (BP) control rates and the availability of effective antihypertensive agents, only 50% of these individuals achieve BP control. It is now recognized that many patients will require ≥ 2 antihypertensive agents to achieve BP control. Both the current US and reappraisal of the 2007 European guidelines include dual-combination regimens among recommended treatments for initial HTN therapy. For patients requiring 3 drugs, the combination of agents with complementary mechanisms of action (ie, renin-angiotensin-aldosterone system blocker, calcium channel blocker, and diuretic) has been recognized as rational and effective. Three single-pill triple-drug combinations have recently been approved for use in HTN in the United States: valsartan (VAL)/amlodipine (AML)/hydrochlorothiazide (HCTZ); olmesartan medoxomil (OM)/AML/HCTZ; and aliskiren (ALI)/VAL/HCTZ. Triple-combination regimens have resulted in a greater proportion of patients achieving BP control compared with dual-combination regimens, with significantly lower BP levels documented after only 2 weeks at maximum doses. Single-pill combinations offer convenience to address barriers to BP control such as poor adherence to therapy and therapeutic inertia. Additional benefits of combining antihypertensive agents from different classes include improved efficacy, safety, and reduction of cardiovascular risk. In patients with essential HTN for whom dual therapy is inadequate, single-pill triple-drug therapy can offer a simplified and effective treatment strategy. PMID:22104451

    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.

  2. Intensive combined modality therapy of small round cell and undifferentiated sarcomas in children and young adults

    International Nuclear Information System (INIS)

    Seventy-five patients (ages 4-35 years) with the following small round cell tumors and undifferentiated sarcoma were treated at the National Cancer Institute: Ewing's sarcome (n=32), peripheral neuroepithelioma (n=14), rhabdomyosarcoma (n=24), undifferentiated sarcoma (n=5). Most patients had poor prognostic features including 36 (48%) with metastatic disease, and 42 (56%) with central (truncal) tumors (22 in the pelvis). Treatment included 5 cycles of intensive induction chemotherapy with vincristine, cyclophosphamide and adriamycin, plus aggressive local radiation therapy using simulation and computerized treatment planning for all patients. Thereafter, complete clinical responses were consolidated with intensive chemotherapy, total body irradiation and autologous bone marrow transplantation. There were three local only failures, 10 local plus distant failures, 36 distant only failures, 3 treatment-related deaths, and one intercurrent death. Overall actuarial survival and event-free survival at 4 years are 49 and 29%, respectively. Actuarial freedom from local progression was seen in 74% of patients at 4 years, quite remarkable considering the bulk and location of most of these tumors. Without aggressive surgery, many of these high risk patients had satisfactory outcomes, but better systemic treatments are still needed.(author). 44 refs.; 8 figs.; 6 tabs

    Traumatic brain injury (TBI) is a significant health care crisis that affects two million individuals in the United Sates alone and over ten million worldwide each year. While numerous monotherapies have been evaluated and shown to be beneficial at the bench, similar results have not translated to the clinic. One reason for the lack of successful translation may be due to the fact that TBI is a heterogeneous disease that affects multiple mechanisms, thus requiring a therapeutic approach that can act on complementary, rather than single, targets. Hence, the use of combination therapies (i.e., polytherapy) has emerged as a viable approach. Stringent criteria, such as verification of each individual treatment plus the combination, a focus on behavioral outcome, and post-injury vs. pre-injury treatments, were employed to determine which studies were appropriate for review. The selection process resulted in 37 papers that fit the specifications. The review, which is the first to comprehensively assess the effects of combination therapies on behavioral outcomes after TBI, encompasses five broad categories (inflammation, oxidative stress, neurotransmitter dysregulation, neurotrophins, and stem cells, with and without rehabilitative therapies). Overall, the findings suggest that combination therapies can be more beneficial than monotherapies as indicated by 46% of the studies exhibiting an additive or synergistic positive effect versus on 19% reporting a negative interaction. These encouraging findings serve as an impetus for continued combination studies after TBI and ultimately for the development of successful clinically relevant therapies. PMID:27166858

    Respiratory lung infections due to multidrug-resistant (MDR) superbugs are on a global upsurge and have very grim clinical outcomes. Their MDR profile makes therapeutic options extremely limited. Although a highly toxic antibiotic, colistin, is favored today as a "last-line" therapeutic against these hard-to-treat MDR pathogens, it is fast losing its effectiveness. This work therefore seeks to identify and tailor-make useful combination regimens (that are potentially rotatable and synergistic) as attractive alternative strategies to address the rising rates of drug resistance. Three potentially rotatable ternary dry powder inhaler constructs (each involving colistin and 2 other different-classed antibiotics chosen from rifampicin, meropenem, and tigecycline) were identified (with distinct complementary killing mechanisms), coformulated via spray drying, evaluated on their aerosol performance using a Next-Generation Impactor and tested for their efficacies against a number of MDR pathogens. The powder particles were of respirable size (d50, 3.1 ± 0.3 μm-3.4 ± 0.1 μm) and predominantly crumpled in morphology. When dispersed via a model dry powder inhaler (Aerolizer(®)) at 60 L/min, the powders showed concomitant in vitro deposition with fine particle fractions of ∼53%-70%. All formulations were successfully tested in the laboratory to be highly effective against the MDR pathogens. In addition, a favorable synergistic interaction was detected across all 3 formulations when tested against MDR Pseudomonas aeruginosa. PMID:27019964

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

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

  10. Therapy of combined radiation injuries with hemopoietic growth factors

    International Nuclear Information System (INIS)

    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

The BxPC-3 pancreatic cancer xenogeneic mice model received treatment with physiological saline, inhibition of SIRT1, gemcitabine, and combination therapy with inhibition of SIRT1 and gemcitabine in vivo and the results showed that the tumor volumes decreased and the survival rate within 45 days increased according to the order of the given drugs and the difference was significant (P < 0.05.Conclusion: Combination therapy with inhibition of SIRT1 and gemcitabine could improve efficacy and survival time in a BxPC-3 pancreatic cancer xenogeneic mice model, compared with single inhibition of SIRT1, or single

  12. Soft tissue sarcoma of the extremity. Limb salvage after failure of combined conservative therapy

    International Nuclear Information System (INIS)

    Purpose: To assess the results of salvage therapy using surgery alone or surgery and re-irradiation for patients with locally recurrent extremity soft tissue sarcoma (STS) following conservative surgery and radiotherapy. Materials and methods: 25 patients with locally recurrent STS after conservative surgery and irradiation were assessed between 1990 and 1995. Two patients with concurrent systemic relapse were treated palliatively. Seven patients were not candidates for conservative re-excision and underwent amputation, 11 patients underwent conservative resection without irradiation. Seven of these patients relapsed, and five went on to receive combined conservative surgery and re-irradiation. A further five patients initially received combined retreatment, for a total of ten patients treated with combined conservative surgery and re-irradiation. Six of these ten patients were treated with brachytherapy alone, one with brachytherapy and external beam therapy, and three with external beam therapy alone. The median retreatment dose was 49.5 Gy (range 35-65 Gy), and the median cumulative soft tissue dose was 100 Gy (range 93-120 Gy). Results: The median follow-up from the most recent treatment is 24 months (range 7-42 months). At the last follow-up 14 patients are alive and disease free; two are alive with local disease and four with systemic disease, and five are dead of disease. Overall local control is(19(23)) (91%). The local control for patients treated with conservative excision without irradiation is(4(11)) (36%) and for conservative excision with re-irradiation (10(10)) (100%). Six (60%) of these patients experienced significant post-irradiation wound-healing complications, but three have recovered fully. Functional scores for the entire treated group are significantly lower after treatment, as are those for patients undergoing combined surgery and re-irradiation, but 70% of those treated with conservative surgery and re-irradiation had a good or excellent

    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 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.

    We report on a 47-year-old man who was initially treated with finasteride for androgenetic alopecia. Despite continuous treatment, after year 4 his hair density was not as good as at year 2, and low-dose dutasteride at 0.5 mg/week was added to the finasteride therapy. This resulted in a dramatic increase in his hair density, demonstrating that combined therapy with finasteride and dutasteride can improve hair density in patients already taking finasteride.

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

    Anti-rotaviral activities of Sophora flavescens extract (SFE) and stevioside (SV) from Stevia rebaudiana Bertoni either singly or in various combinations were examined in vitro and in vivo using a porcine rotavirus G5[P7] strain. Combination of SFE and SV inhibited in vitro virus replication more efficiently than each single treatment. In the piglet model, SV had no effect on rotavirus enteritis, whereas SFE improved but did not completely cure rotaviral enteritis. Interestingly, combination therapy of SFE and SV alleviated diarrhea, and markedly improved small intestinal lesion score and fecal virus shedding. Acute toxicity tests including the piglet lethal dose 50, and body weight, organ weight and pathological changes for the combination therapy did not show any adverse effect on the piglets. These preliminary data suggest that the combination therapy of SV and SFE is a potential curative medication for rotaviral diarrhea in pigs. Determination of the efficacy of this combination therapy in other species including humans needs to be addressed in the future. PMID:24704033

  3. Long term observations in combined modality therapy for limited stage small cell lung cancer

    International Nuclear Information System (INIS)

    overall survival for the concurrent group was 23.8 months, vs. 19.2 months for the sequential group (p=0.015). Similarly, the median disease free survival was higher in the concurrent group (p=0.033). Thirty-five patients (49%) treated concurrently survived two years, vs. 38 (32%) of the sequential cohort (p=0.017). This significant improvement in survival persisted at three years (35% vs. 22%, p=0.044). The sequential arm had a higher number of intercurrent deaths. Disease free survival was strongly influenced by KPS >=90 (p=0.0008). Those patients who presented with pleural effusion were less likely to survive 2 years (p=.002). Patients with a normal LDH had an improved median overall survival (p=0.013). On multivariate analysis, when controlling for the significant covariates of KPS and pleural effusion, The overall survival of the concurrent arm remained statistically significantly superior to the sequential arm (p=0.03). Conclusion: Selected patients with favorable performance status benefitted from a concurrent treatment approach, achieving an improvement in overall survival. Following a complete response to combined modality therapy, the early administration of PCI may be beneficial. Pretreatment patient characteristics including good performance status, absence of pleural effusion, and normal LDH were found to be highly significant as prognostic factors. Patients with favorable pretreatment characteristics should continue to be offered enrollment in randomized trials evaluating the impact of novel sequencing and treatment regimens. The search for improved systemic agents, as well as the optimal timing and dose of thoracic irradiation in the concurrent setting, must be aggressively pursued

Photobox Waldmann 7002 K (Germany with TL-01 lamps which generate radiation in 310 – 315 nm wavelength range with maximum 311 nm wavelength emission. The procedures have been carried out 4 times a week. Methotrexate should be received as tours 7.5 mg once a week, according to Weinstein — Frost scheme under the supervision of laboratory parameters. The treatment course consists of three tours. Treatment has been carried out on a background of traditional therapy.The comparison group received conventional therapy in combination with narrowband UVB phototherapy and nonsteroidal anti-infammatory drugs. Evaluation of the effectiveness of the therapy was based upon dynamic assessment of PASI and DLQI indexes and proved by earlier reduction of clinical symptoms than in the comparison group, which resulted in reduction of absolute PASI and DLQI values. No adverse effects caused by the therapy undertaken have been noted. The results of the study appear to prove safety and effectiveness of such therapy in treatment of psoriasis.

    Intratumoral heterogeneity of signaling networks may contribute to targeted cancer therapy resistance, including in the highly lethal brain cancer glioblastoma (GBM). We performed single-cell phosphoproteomics on a patient-derived in vivo GBM model of mTOR kinase inhibitor resistance and coupled it to an analytical approach for detecting changes in signaling coordination. Alterations in the protein signaling coordination were resolved as early as 2.5 days after treatment, anticipating drug resistance long before it was clinically manifest. Combination therapies were identified that resulted in complete and sustained tumor suppression in vivo. This approach may identify actionable alterations in signal coordination that underlie adaptive resistance, which can be suppressed through combination drug therapy, including non-obvious drug combinations.

    The outcome was retrospectively examined and prognostic factors were discussed for arterial chemo-infusion therapy (ACT) through an implanted reservoir system and radiation therapy (RT) in patients with unresectable intrahepatic cholangiocarcinoma (CCC). ACT plus RT were conducted to 25 patients (mean age 61.7 y, M/F 12/13, stage III-IVB) during 10 years from 1996 to 2005 with various regimens of cisplatin (CDDP), 5- fluorouracil (FU), epirubicin (FARM), mitomycin C (MMC) plus 39-50 Gy of radiation in a fractionated manner partly involving internal RT (2 cases, 15 Gy) and RT for metastatic bone (1, 25 Gy). The survival rates at 1, 2 and 3 years after ACT+RT were respectively 52.5, 43.7 and 28.1%; total efficacy (PR) was 36% (9/25) at 6 months; and significantly good prognostic factors were found to be female and absence of metastasis remote and/or lymphatic around artery. Authors concluded that ACT+RT was a meaningful treatment for highly advanced non-respectable CCC and that multi-center cooperative study was necessary for establishing the usefulness and application of the therapy.

    International Nuclear Information System (INIS)

    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 3H-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

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

    Directory of Open Access Journals (Sweden)

    Nikita Pozdeyev

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

    International Nuclear Information System (INIS)

    Purpose: To examine prognostic indicators in aggressive fibromatoses that may be used to optimize case-specific management strategy. Methods and Materials: One hundred and seven fibromatoses presenting between 1971 and 1992 were analyzed. The following treatment modalities were utilized: (a) surgery alone for 51 tumors; (b) radiation alone for 15 tumors; and (c) radiation and surgery (combined modality) for 41 tumors. Outcome analysis was based on 5-year actuarial local control rates. Results: Control rates among surgery, radiation therapy, and combined modality groups were 69%, 93%, and 72%. Multivariate analysis identified age 60 Gy was seen in patients with unresected or gross residual disease. Of the patients, 23 with disease involving the plantar region had a control rate of 62%, with significantly worse outcomes in children. Conclusions: These results are consistent with those found in the relevent literature. They support primary resection with negative margins when feasible. Radiation is a highly effective alternative in situations where surgery would result in major functional or cosmetic defects. When negative surgical margins are not achieved in recurrent tumors, radiation is recommended. Perioperative radiation should be considered in other high-risk groups (recurrent disease, positive margins, and plantar tumors in young patients). Doses of 60-65 Gy for gross disease and 50-60 Gy for microscopic residual are recommended. Observation may be considered for primary tumors with disease remaining in situ when they are located such that progression would not cause significant morbidity. Although plantar lesions in children may represent a group at high risk for recurrence or aggressive behavior, the greater potential for radiation-induced morbidity in this group must also temper its use. Given the inconsistent nature and treatment response of this tumor, it is fundamental that treatment recommendations should be made based on the risk:benefit analysis for

    Full Text Available Monotherapeutic options for carbapenem resistant infections are limited. Studies suggest that combination therapy may be associated with better outcomes than monotherapies. However, this is still controversial. This study assessed, the efficacy of combination therapy against carbapenem resistant Enterobacteriaceae harboring singly various ESBL or carbapenemase encoding genes. Thus, four isolates harboring either blaCTXM-15, blaCTXM-15 and blaOXA-48, blaNDM-1, or blaKPC-2 genes were selected for testing. Minimal Inhibitory Concentration (MIC was determined by broth dilution method. Gene transcript levels on single and combined treatments were done in vitro and in vivo by q RT-PCR. Assessment of treatments was done in BALB/c mice according to a specific protocol. As such, the qRT-PCR revealed a significant decrease of transcript levels in all isolates upon using rifampicin or tigecycline, singly or in combination with colistin. However, variable levels were obtained using colistin singly or in combination with meropenem or fosfomycin. In vivo assessment showed that all combinations used were effective against isolates harboring blaCTXM-15, blaOXA-48, and blaNDM-1. Conversely, the most significant combination against the isolate harboring blaKPC-2 gene was colistin with carbapenem, fosfomycin, or kanamycin. As a conclusion, combination therapy selected based on the type of carbapenemase produced, appeared to be non-toxic and might be effective in BALB/c mice. Therefore, the use of a rationally optimized combination therapy might lead to better results than monotherapy, however, clinical trials are needed for human consumption.

  15. Toxicity of aggressive multimodality therapy including cisplatinum, bleomycin and methotrexate with radiation and/or surgery for advanced head and neck cancer

    International Nuclear Information System (INIS)

    A combined modality regimen employing induction chemotherapy with cisplatinum, bleomycin and methotrexate followed by surgery and/or radiation therapy was initiated in patients with advanced squamous cell carcinoma of the head and neck. In the first 23 patients treated with this program there was a 90% response rate to induction chemotherapy (9% CR and 81% PR). Toxicity associated with radiotherapy, but not surgery, was increased with 11 of 23 patients (48%) who experienced some toxicity during or immediately after radiotherapy. Mucositis was worse than expected and severe delayed mucositis was seen in 2 patients, one of whom required hospitalization. Late complications, possibly related to therapy included one myocardial infarction and one episode of hypoglycemia, both of which were fatal. One other patient voluntarily failed to take prescribed oral leucovorin, dying of unrescued methotrexate toxicity during adjuvant therapy, a questionable suicide. Further follow-up analysis of failure will be necessary to determine if the value of a combined modality regimen in producing an increased cure rate and long term survival will out weigh increased toxicity

At the time of diagnosis the surgical treatment was decided to abstain because of the trachea invasion in 9 patients, wide mediastinal invasion in 2 patients and contralateral mediastinal lymph nodes metastases in 2 patients; pneumonectomy was not possible due to the poor respiratory function in 7 patients. Neoadjuvant therapy included 3 courses of chemotherapy and endobronchial photodynamic therapy. During the operation, along with the lung resection (pneumonectomy - 15, lobectomy - 5), photodynamic therapy of the resection margins were carried out. No adjuvant treatment was done. Preoperative treatment led to partial regress of the disease in all cases; the goal of surgery was the complete tumor removal. No complications of the photodynamic therapy were observed. 18 surgical interventions were radical and two non-complete microscopically (R1). Postoperative morbidity was 20%, one patient died due to massive gastrointestinal bleeding. The average follow-up period was 18 months: 19 patients were alive, of them 18 with no signs of the disease recurrence. The first experience of the combined use of neoadjuvant chemotherapy and surgery with pre- and intraoperative photodynamic therapy demonstrates safety and efficacy of the suggested treatment tactics.

  2. Absence of osteoporosis in an adult population undergoing combined immunosuppressive therapy for chronic active hepatitis

    International Nuclear Information System (INIS)

    Thirty adult patients who had received 1-20 years of combined immunosuppressive therapy (CIT) for chronic active hepatitis (CAH) underwent dual-photon absorptiometry (DPA) of L-2 through L-4 CIT consisted of azathioprine and prednisone supplemented and calcium and vitamin D. Osteoporosis is known to occur in patients with CAH, and in other clinical settings prednisone therapy has been shown to induce osteoporosis. For these 30 adult CAH patients undergoing CIT, absorptiometric measurements did not differ significantly from those in age- and sex-matched normal controls. CIT therapy for CAH may have arrested the long-term loss of bone mineral often produced by CAH. The authors' hypothesize that a combined azathioprine and prednisone regimen with reduced corticosteroid requirements was responsible for this favorable outcome

  3. Nonsurgical combined modality therapies in non-small cell lung cancer

    International Nuclear Information System (INIS)

    Nonsurgical combined approaches of non-small cell lung cancer represent a concept that has only been investigated so far with chemotherapy and radiation therapy. Thoracic irradiation of locoregional disease is associated with a high rate of local control and a 5-10% long-term (5-year) survival; however, distant metastases remain the main cause of failure. This observation suggests that the tumor is often microscopically disseminated at the time of diagnosis. Systemic therapy therefore must be associated to radiation therapy to try to control both the undetectable metastases and the local disease. However, the results reported so far have been disappointing, probably because of the modest activity of the available chemotherapy. Further progress with the combined approach requires new developments in the chemotherapy of non-small cell lung cancer, particularly the introduction of new active drugs.67 references

    2011-01-01

    Antiepileptic drug combination therapy remains an empirical second-line treatment approach in trigeminal neuralgia, after treatment with one antiepileptic drug or other nonantiepileptic drugs have failed. The results in three patients followed in our clinic are not sufficient to draw definitive conclusions, but suggest the possibility of developing this type of therapeutic approach further.

    Erythropoietin (EPO) and granulocyte-colony stimulating factor (G-CSF) are known to have neuroprotective actions. Based on previous reports showing the synergistic effects of EPO+G-CSF combination therapy in experimental models, we investigated the safety of EPO+G-CSF combination therapy in patients with chronic stroke. In a pilot study, 3 patients were treated with EPO and G-CSF for 5 consecutive days, with follow-up on day 30. In an exploratory double-blind study, 6 patients were allocated to treatment with either EPO+G-CSF or placebo. Treatment was applied once a day for 5 days per month over 3 months. Participants were followed up for 6 months. To substantiate safety, vital signs, adverse events, and hematological values were measured on days 0, 5, and 30 in each cycle and on day 180. Functional outcomes were determined on day 0 and 180. In the laboratory measurements, EPO+G-CSF combination therapy significantly elevated erythropoietin, CD34⁺ hematopoietic stem cells, white blood cells, and neutrophils on day 5 of each cycle. There were no observations of serious adverse events. In the functional outcomes, the grip power of the dominant hand was increased in the EPO+G-CSF treatment group. In conclusion, this exploratory study suggests a novel strategy of EPO+G-CSF combination therapy for stroke patients. PMID:27043535

    2007-01-01

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

  17. Optimization of combination therapy of arsenic trioxide and fractionated radiotherapy for malignant glioma

    International Nuclear Information System (INIS)

    Purpose: The primary objective was to optimize the combined treatment regimen using arsenic trioxide (ATO) and fractionated radiotherapy for the treatment of malignant glioma. Methods and Materials: Nude mice with human glioma xenograft tumors were treated with fractionated local tumor radiation of 250 cGy/fraction/day and 5 mg/kg ATO for 5-10 days. Results: Time course experiments demonstrated that maximal tumor growth delay occurred when ATO was administered between 0 and 4 h after radiation. The combination treatment of ATO and radiation synergistically inhibited tumor growth and produced a tumor growth delay time of 13.2 days, compared with 1.4 days and 6.5 days for ATO and radiation alone (p < 0.01), respectively. The use of concurrent therapy of radiation and ATO initially, followed by ATO as maintenance therapy, was superior to the use of preloading with ATO before combined therapy and produced a tumor growth delay time of 22.7 days as compared with 11.7 days for the ATO preloading regimen (p < 0.01). The maintenance dose of ATO after concurrent therapy was effective and important for continued inhibition of tumor growth. Conclusions: The combined use of fractionated radiation and ATO is effective for the treatment of glioma xenograft tumors. ATO was most effective when administered 0-4 h after radiation without pretreatment with ATO. These results have important implications for the optimization of treatment regimen using ATO and fractionated radiotherapy for the treatment of brain tumors

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

    Directory of Open Access Journals (Sweden)

    Sheeja M Krishnan

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

Translocations involving ALK, the anaplastic lymphoma kinase gene, are associated with a favorable clinical outcome. Such ALK-positive ALCLs are usually responsive to a multidrug chemotherapy with CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone. However, there is no general consensus on the optimal therapy for relapsed or refractory ALCL. We report the case of a 24-year-old male suffering from ALK-positive ALCL with an uncommon manifestation of only extranodal disease in the gastric cardia region that showed primary refractoriness to standard CHOP chemotherapy. A combination therapy consisting of the anti-CD30 drug conjugate, brentuximab vedotin, and classical lymphoma salvage regimen DHAP (cisplatin, high-dose cytarabine and dexamethasone was administered. Following two treatment cycles in 21-day intervals, the lymphoma showed considerable regression based on imaging diagnostics and no evidence of vital lymphoma in a subsequent biopsy. We did not observe any increase in toxicity; in particular, polyneuropathy and febrile neutropenia were not observed. In summary, we report that the antibody-drug conjugate brentuximab vedotin and a classical regimen used for aggressive lymphoma, DHAP, could be combined as salvage therapy in a case of refractory ALK-positive ALCL. Phase I/II studies will be required for safety and efficacy analysis.Keywords: anaplastic large cell lymphoma (ALCL, refractory/relapsed lymphoma, anti-CD30 drug conjugate, DHAP

  5. Combination therapy for advanced oral squamous cell carcinoma with radiation and bleomycin, 1

    International Nuclear Information System (INIS)

    Twenty-five patients of advanced oral cancers (squamous cell carcinoma) were treated with combination of radiation and bleomycin in the first course of treatment, and then treated with either Ra needle or 198Au grain implantation, 2 to 3 weeks after the first course of treatment for severe mucositis. The treatments were performed during 1975 to 1977. In the combination therapy, external irradiation (daily 250 rad) of Telecobalt γ-ray or Betatron electron beam was given by 4 fractionations per week during 2.5 to 3 weeks (2,500 to 3,000 rad). Bleomycin (5 mg) was injected intramuscularly about 30 min before the irradiation, giving a total of 50 to 60 mg during therapy. In the second course of therapy, Ra needle or 198Au grain implants were employed in 14 cases and further external irradiation was given for the remaining cases except one which had two primary origins of cancer in the tongue and liver. As a result of the combination therapy, 12 primary tumors out of 25 cases markedly regressed (more than 50% regression) and by subsequent radiotherapy, 11 primary tumors out of 24 were completely controlled during more than 14 months of follow-up observation. The tongue cancer in one exceptional case was controlled by the combination of radiation (3,000 rad) and bleomycin (60 mg) alone. Fifteen of 25 patients are still alive, while 10 patients died of cancer. This therapy of combined irradiation and bleomycin seems to be effective on advanced oral cancers because the local tumor control rate increased markedly. (author)

  6. Combined analgesics in (headache pain therapy: shotgun approach or precise multi-target therapeutics?

    Directory of Open Access Journals (Sweden)

    Fiebich Bernd L

    2011-03-01

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

    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.

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

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

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

    Currently, in vitro synergy with colistin has not translated into improved clinical outcomes. This study aimed to compare colistin combination therapy to colistin monotherapy in critically ill patients with multi-drug resistant gram-negative (MDR-GN) pneumonia. This was a retrospective analysis of critically ill adult patients receiving intravenous colistin for MDR-GN pneumonia comparing colistin combination therapy to colistin monotherapy with a primary endpoint of clinical cure. Combination therapy was defined by administration of another antibiotic to which the MDR-GN pathogen was reported as susceptible or intermediate. Ninety patients were included for evaluation (41 combination therapy and 49 monotherapy). Baseline characteristics were similar between groups. No difference in clinical cure was observed between combination therapy and monotherapy in univariate analysis, nor when adjusted for APACHE II score and time to appropriate antibiotic therapy (57.1 vs. 63.4 %, adjusted OR 1.15, p = 0.78). Microbiological cure was significantly higher for combination therapy (87 vs. 35.5 %, p Colistin combination therapy was associated with a significant improvement in microbiological cure, without improvement in clinical cure. Based on the in vitro synergy and improvement in microbiological clearance, colistin combination therapy should be prescribed for MDR-GN pneumonia. Further research is warranted to determine if in vitro synergy with colistin translates into improved clinical outcomes. PMID:27230510

    International Nuclear Information System (INIS)

    Purpose: To improve the therapeutic effectiveness of hilar cholangiocarcinoma and prolong the survival period by stenting and local therapy. Materials and methods: Twenty-four patients (men 8, women 16) with hilar cholangiocarcinoma were treated by percutaneous transhepatic cholangiography and drainage (PTCD), 18 of them were treated by local therapy and placement of stents, then PTCD tubes were pulled out one week later. Another 6 patients were treated only by PTCD. Results: Among 24 patients receiving PTCD, total bilirubin value was decreased in 22 patients, and no change occurred in 2 patients, who died within 1 month. For the 18 patients receiving combined treatment of local therapy and placement of metallic stents after PTCD, the mean survival period was 10 months and the longest survival period was 24 months, while the mean survival period with tube-free was 5.5 months, and the longest survival period with tube-free was 17 months. Another 6 patients were treated only by PTCD, with mean survival period of 2 months and the longest survival period of 6 months. conclusion: (1) The survival time for patients receiving local therapy and placement of metallic stent was much longer than those receiving PTCD alone. (2) Unfavorable prognosis occurred when BIL level had no change or even an increase after PTCD. (3) The combination of placement of metallic stents and local therapy after PTCD offered an effective nonoperative method in the treatment of hilar cholangiocarcinoma

    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.

    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 therapies. Given the reduced risk of mortality seen when empagliflozin was added to standard care in patients at high cardiovascular risk, as well as the lack of alternative options for

  15. The combination of suicide gene therapy and radiation enhances the killing of nasopharyngeal carcinoma xenographs

    International Nuclear Information System (INIS)

    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.

    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.

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

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

  1. Combination therapy with IFN-beta, ACNU and radiation (IAR) for malignant brain tumors

    International Nuclear Information System (INIS)

    In order to analyze the efficacy of combination therapy with Hu-IFN-β, ACNU and radiation (IAR), nine patients with malignant glioma were treated as a control study. They received 100 x 104 IU Hu-IFN-β daily for seven days intravenously or intratumorally, 3 mg/kg ACNU on day 2 and 5,000 - 6,000 rads of radiation from day 3. Four out of nine patients showed complete response and one partial response with this IAR therapy. Case 1 was a 64-year-old man who had glioblastoma in the left frontal lobe. Postoperative residual tumors disappeared completely with this therapy. Case 3 was a 8-year-old girl who had an enhanced high-density lesion in the medulla oblongata and pons. After IAR therapy, the high-density lesion was completely vanished and her clinical manifestations of multiple cranial nerve palsy and pyramidal sign were improved remarkably. The major side effects of IAR therapy were mild or moderate myelosuppression, and some patients also showed hepatic dysfunction, mild fever and gastrointestinal toxicities. However, all these side effects were mild and transient and soon recovered to normal levels. These results suggest that IAR therapy is effective and will prolong the survival time of patients with malignant glioma. (author)

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

    In 44 patients with chronic plaque psoriasis anthralin therapy was used as high-strength short-contact therapy in a bilateral comparison of anthralin versus 5% crude coal tar-anthralin combination. These two trials were undertaken with and without ultraviolet (UV) irradiation immediately after anthralin therapy. The combined tar-anthralin therapy was significantly less of an irritant during the first 3 weeks of treatment than anthralin alone, and it did not decrease the antipsoriatic efficacy. The use of UV irradiation, either with anthralin or tar-anthralin combination, did not produce an additional therapeutic effect. These findings lead us to prefer combined tar-anthralin therapy because of its lower irritancy in comparison with anthralin alone and they show the ineffectiveness of additional UV irradiation under the conditions of this study.

  6. Radiotherapy combined with hormonal therapy in prostate cancer: the state of the art

    International Nuclear Information System (INIS)

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

    Statins, angiotensin-converting enzyme (ACE) inhibitors, and calcium channel blockers (CCBs) have markedly changed the clinical progression of patients with coronary artery disease (CAD). The goal of this paper is to review the rationale and evidence for combining these three drug classes in hypertensive patients with hypercholesterolemia or CAD. Data sources include a literature search for publications on the use of a statin combined with various antihypertensive drugs in patients with hypertension and hypercholesterolemia or stable CAD. Hypercholesterolemia and hypertension constitute major physiological risk factors of ischemic heart disease. Current guidelines recommend a global approach to risk management, using agents that address as many risk factors as possible. Dual combination therapies are an important component of guideline-recommended therapy in hypertension. Our review of the literature indicates that triple therapy with a statin, ACE inhibitor, and CCB is associated with a significant reduction in major cardiovascular events. For example, a post hoc analysis in 1056 patients with stable CAD participating in the EUROPA trial indicated that the addition of perindopril to a CCB and a lipid-lowering agent was associated with a 46 % reduction in the composite of cardiovascular death, myocardial infarction, and resuscitated cardiac arrest (p = 0.023). In addition, single pill formulations are known to result in better adherence to the treatment. Single-pill formulations that combine a statin, an ACE inhibitor, and a CCB appear to offer an effective approach to the management of global cardiovascular risk. PMID:27256435

    Despite more modern therapeutics approaches and the use of new drugs for chemotherapy, patients with ovarian cancer still have poor prognosis and therefore, new strategies for its cure are highly needed. One of the promising ways is combined therapy, which has many advantages as minimizing drug resistance, enhancing efficacy of treatment, and reducing toxicity. Combined therapy has rich and successful history in the field of ovarian cancer treatment. Currently use therapy is usually based on platinum-containing agent (carboplatin or cisplatin) and a member of taxanes (paclitaxel or docetaxel). In the mid-2000s this standard regimen has been expanded with bevacizumab, monoclonal antibody directed to Vascular Endothelial Growth Factor (VEGF). Another drug combination with promising perspectives is WP 631 given together with epothilone B (Epo B). WP 631 is a bisanthracycline composed of two molecules of daunorubicin linked with a p-xylenyl linker. Epo B is a 16-membered macrolide manifesting similar mechanism of action to taxanes. Their effectiveness against ovarian cancer as single agents is well established. However, the combination of WP 631 and Epo B appeared to act synergistically, meaning that it is much more potent than the single drugs. The mechanism lying under its efficacy includes disturbing essential cell cycle-regulating proteins leading to mitotic slippage and following apoptosis, as well as affecting EpCAM and HMGB1 expression. In this article, we summarized the current state of knowledge regarding combined therapy based on WP 631 and Epo B as a potential way of ovarian cancer treatment. PMID:26944437

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

    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.

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

    Malini Olivo

    2010-05-01

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

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

  13. Optimization of combination of peptide receptor radionuclide therapy (PRRT) and temozolomide therapy using SPECT/CT and MRI in mice

    International Nuclear Information System (INIS)

    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 177Lu-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 111In-uptake 24 hours after administration of 30 MBq 111In-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 mm3. Results: single treatment with 177Lu-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 111In-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. 101

    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

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

    FederAnziani Senior Italia and SIU - Italian Society of Urology - have decided to work together to draft a document focussing on Benign Prostatic Hyperplasia (BPH), and to stress the importance of adherence with pharmacological treatment in this setting, from both a scientific and a patient standpoint. Starting from a literature search, the two associations analysed to what extent an increase in treatment adherence amongst these patients influences hospital savings and to what extent therapy persistence levels are affected by monotherapy rather than free drug combinations. These estimates were performed only on patients taking medicinal products belonging to the 5 α-reductase inhibitors (5ARI) class that, although not indispensable, are the compounds that bring the greatest benefits, especially in the elderly and for which we know that every additional 30 days of therapy reduced the likelihood of acute urinary retention (AUR) and surgery by 14% and 11% respectively *. The results show that the use of fixed combination therapy would involve an increase in persistence due to the lower rate of patients abandoning treatment over time. Each 30 day-increment of 5ARI therapy, i.e. for an expenditure of 10.6 million euros extra per year for 5ARI medication, savings of approximately 24.3 million euros in hospital costs could be achieved.

    2014-02-01

    Vascular endothelial growth factor A (VEGF-A), commonly known as VEGF, is one of the primary factors that affect tumor angiogenesis. It was found to be expressed in cancer cell lines including oral squamous cell carcinoma. Photodynamic therapy (PDT) is a novel therapeutic modality to treat cancer by using a photosensitizer which is activated by a light source to produce reactive oxygen species and mediates oxygen-independent hypoxic conditions to tumor. Another emerging treatment to cure cancer is the use of interference RNA (e.g. siRNA) to silence a specific mRNA sequence. VEGF-A was found to be expressed in oral squamous cell carcinoma and overexpressed after 24 hour post-PDT by Western blot analysis. Cell viability was found to decrease at 25 nM of transfected VEGF-A siRNA. In vitro combined therapy of PDT and VEGF-A siRNA showed better response as compared with PDT and gene therapy alone. The results suggest that PDT combined with targeted gene therapy has a potential mean to achieve better therapeutic outcome.

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

    Full Text Available The antitumor effects of indomethacin and interleukin 2 (IL-2 were studied in C3H/HeJ mice inoculated with MH134 hepatoma cells. Combined treatment with indomethacin and IL-2 augmented natural killer (NK cells in mice with MH134-induced peritoneal carcinomatosis, and the survival of the treated mice was significantly longer than the non-treated mice. In animals with subcutaneous MH134 tumors, the combined therapy with indomethacin and IL-2 significantly suppressed tumor growth and induced complete regression of the tumor in three out of five mice. These results suggest that indomethacin and IL-2 therapy could be effective on human gastrointestinal cancer cells as well.

Patients (n= 65; 19 males and 46 females with essential HT accompanied by metabolic disorders, history of previous ineffective antihypertensive therapy were included into the study. Patients were randomized into 2 groups. Group V/A was treated with valsartan and amlodipine in fixed-dose combinations of 160/5 and 160/10 mg depending on blood pressure (BP level. Patients of group L/A were treated with losartan 100 mg and amlodipine 5 or 10 mg daily. Treatment duration was 24 weeks. Changes in BP level, and left ventricular hypertrophy (LVH regression were assessed. Economic evaluation was performed on the basis of modeling with specialized software Decision Tree 4.xla.Results. 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. It would take 286.698.7 RUR additionally for one additional QALY in the treatment with V/A, and it is

  8. Role of targeted therapy in combination with surgery in renal cell carcinoma.

    Bex, Axel; Powles, Thomas; Karam, Jose A

    2016-01-01

    Surgical complete resection is the only curative treatment of renal cell carcinoma including patients with locally advanced disease and those with limited metastatic disease. Patients at high risk of recurrence after complete resection might theoretically benefit from adjuvant and neoadjuvant systemic treatment strategies to prolong disease-free survival and ultimately overall survival. Another rationale for using targeted therapy includes downsizing/downstaging of surgically complex locally advanced renal cell carcinoma to facilitate complete resection or primary tumors to allow for nephron-sparing strategies. Unfortunately, a considerable percentage of patients are diagnosed with metastatic disease at first presentation. Although large population-based studies consistently show a survival benefit after cytoreductive nephrectomy in the targeted therapy era, confounding factors preclude definite conclusions for this heterogeneous patient group until ongoing phase III trials are published. Presurgical targeted therapy has been proposed to identify patients with clinical benefit and potentially long-term survival after cytoreductive nephrectomy. Recently, the use of targeted therapy before or after local treatment of metastases has been reported in small retrospective series. The present review revisits the current evidence base of targeted therapy in combination with surgery for the various disease stages in renal cell carcinoma. PMID:26238981

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.

  10. Mammographic changes in postmenopausal women : comparative effects between continuous combined hormone and single estrogen replacement therapy

    International Nuclear Information System (INIS)

    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

  12. Radiotherapy for aggressive fibromatosis

    International Nuclear Information System (INIS)

    Purpose/Objective: To evaluate local control with radiotherapy for aggressive fibromatosis. Materials and Methods: Fifty-three patients with histologically confirmed aggressive fibromatosis were treated with radiotherapy at the University of Florida between March 1975 and June 1992. The minimum length of follow-up was 2 years; 88% of patients had follow-up for at least 5 years. Thirty-nine patients had lesions in an extremity and 14 patients had lesions in the trunk. Twenty-nine patients were treated for gross disease. Patients were treated with total doses between 35 Gy and 70 Gy; 83% of patients received 50 Gy to 60 Gy. Results: Local control was achieved in 23 of 29 patients (79%) treated for postoperative microscopic residual disease. Local control was achieved in 21 of 24 patients (88%) treated for gross disease; gross disease was controlled in 8 of 8 patients with previously untreated lesions, and in 13 of 16 patients treated for postoperative gross residual and recurrent disease. Overall, aggressive fibromatosis was locally controlled in 83% of treated patients. All 9 treatment failures occurred with extremity lesions 4 to 68 months after initiation of treatment. Of the 9 recurrences, 4 were out-of-field, 3 were in-field, and 4 occurred at the margin of the irradiated field. Salvage was successful in 8 of 9 patients in whom salvage was attempted with surgery alone or combined with postoperative radiotherapy. A functional limb was maintained in 38 of 39 patients with extremity or limb girdle lesions. The most serious complication of treatment was pathologic fracture, which occurred in 3 of 53 treated patients; all 3 fractures healed with conservative management. Conclusion: Radiotherapy is a valuable adjunct to surgery in the management of aggressive fibromatosis and can be used alone in patients with unresectable or inoperable disease

Treating illness promptly with artemisinin-based combination therapy (ACT) is likely to cure people and avoid the disease progressing to more severe forms and death. In many countries, ACT use remains low. Part of the problem is that most people seek treatment from the retail sector where ACTs are expensive; this expense is a barrier to their use.

    Malaria parasites carrying genes conferring resistance to antimalarials are thought to have a selective advantage which leads to higher rates of transmissibility from the drug-treated host. This is a likely mechanism for the increasing prevalence of parasites with resistance to chloroquine (CQ) and sulfadoxine-pyrimethamine in sub-Saharan Africa. Combination therapy is the key strategy being implemented to reduce the impact of resistance, but its effect on the transmission of genetically resi...

    Background and Aims: A small mass of melanocytic nevi on the face is commonly treated by surgical resection. This method is associated with cosmetic complications, such as scarring and scar contracture. The use of CO2 Laser treatment to avoid these complications is increasing. However, scarring or recurrence may still occur after CO2 Laser treatment. To resolve these problems, we developed a new Combined Laser Therapy (CLT) protocol using three laser instruments.

    In this paper, we present results of a hyperthermia treatment of malignant tumors using a gyrotron as a radiation source for heating of the cancerous tissue. They clearly demonstrate the efficiency of the irradiation by sub-THz waves, which leads to steady decrease of the volume of the tumor and finally to its disappearance. A combination of hyperthermia and photodynamic therapy (PDT) that utilizes a novel multifunctional photosensitizer has also been explored. In the latter case, the results are even more convincing and promising. In particular, while after a hyperthermia treatment sometimes a regrowth of the tumor is being observed, in the case of combined hyperthermia and PDT such regrowth has never been noticed. Another combined therapy is based on a preheating of the tumor by gyrotron radiation to temperatures lower than the hyperthermia temperature of 43 °C and followed then by PDT. The results show that such combination significantly increases the efficiency of the treatment. We consider this phenomenon as a synergy effect since it is absent when hyperthermia and PDT are applied separately, and manifests itself only when both methods are combined.

    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

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

  14. Investigation of 177Lu-folate based radionuclide tumor therapy in combination with pemetrexed

    International Nuclear Information System (INIS)

    Full text of publication follows. Aim: The antifolate pemetrexed (PMX) was shown to improve the tissue distribution profile of radio-folates by reducing undesired renal accumulation without affecting uptake in the tumor. We hypothesized that PMX would have a dual role in combination with therapeutic radio-folates as it may protect kidneys from radio-nephrotoxicity and contribute to the anticancer effect as a chemotherapeutic and/or radiosensitizing agent. Therefore, the aim of the study was to investigate the combined application of 177Lu-folate and PMX in vitro an in vivo. Material and Methods: The DOTA-folate conjugate (EC0800, Endocyte Inc.) was labeled with 177Lu at high specific activity. In vitro the effects of 177Lu-EC0800 alone and in combination with PMX was tested with FR-positive KB tumor cells using MTT and clonogenic assays. In vivo, undesired effects of 177Lu-EC0800 (20 MBq/mouse) with/without co-application of PMX were investigated in non-tumor bearing mice over six months. Kidney function was monitored by the determination of renal accumulation of 99mTc-DMSA using SPECT. Therapy studies in KB tumor-bearing mice were performed with 177Lu-EC0800 (20 MBq) combined with subtherapeutic (0.4 mg) and therapeutic amounts (1.6 mg) of PMX. Results: Determination of the combination index revealed a synergistic inhibitory effect of 177Lu-EC0800 and PMX on the viability of both FR-positive cancer cell lines in vitro (CI < 0.8). In vivo application of 20 MBq 177Lu-EC0800 impaired kidney function 6 months as demonstrated by a significantly reduced renal uptake of 99mTc-DMSA and elevated plasma levels of blood urea nitrogen. Pre-injection of subtherapeutic amounts of PMX (0.4 mg) protected kidneys effectively as demonstrated by parameters which were in the same range as those of untreated control animals. Therapy studies revealed a 3-fold more pronounced anticancer effect and 25% increased survival if 177Lu-EC0800 was combined with therapeutic amounts of PMX

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

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

    As the immunotherapy of cancer comes of age, adding immunotherapeutic agents to radiation therapy has the potential to improve the outcomes for patients with a wide variety of malignancies. Despite the enormous potential of such combination therapy, laboratory data has been lacking and there is little guidance for pursuing novel treatment strategies. Animal models have significant limitation in combining radiation therapy with immunotherapy and some of the limitations of preclinical models are discussed in this article. In addition to the preclinical challenges, radiation therapy and immunotherapy combinations may have overlapping toxicities, and for both types of therapy, early and late manifestations of toxicity are possible. Given these risks, special attention should be given to the design of the specific Phase I clinical trial that is chosen. In this article, we describe several Phase I design possibilities that may be employed, including the 3 + 3 design (also known as the cohort of 3 design), the continual reassessment method (CRM), and the time-to-event continual reassessment method (TITE-CRM). Efficacy end points for further development of combination therapy must be based on multiple factors, including disease type, stage of disease, the setting of therapy and the goal of therapy. While the designs for future clinical trials will vary, it is clear that these two successful modalities of therapy can and should be combined for the benefit of cancer patients. PMID:25003314

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.

    With the emergence of new oral therapies for metastatic melanoma to the market, as well as ongoing pre-marketing trials and special access schemes, it is important to keep up to date with the side effect profiles of these medications. A common side effect associated with the BRAF inhibitor dabrafenib is severe fever symptoms such as pyrexia and rigors/chills; however, treatment options are limited. We report a patient who was debilitated by severe pyrexia and rigors caused by dabrafenib used in combination with trametinib to treat metastatic melanoma, who was treated with low-dose steroids. To our knowledge, the use of prednisolone for the treatment and prevention of further dabrafenib-associated pyrexia is not published; however, it is a low risk and low cost option that was very effective in this case.

  20. Synergy of combined tPA-edaravone therapy in experimental thrombotic stroke.

    Directory of Open Access Journals (Sweden)

    Yu-Yo Sun

    Full Text Available 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 (p50% 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.

    The main outcomes of the therapies for rheumatoid arthritis (RA) must be preventing, or at least lessening, the development of structural damage. Biological disease-modifying anti-rheumatic drugs (bDMARDs), targeting tumour necrosis factor-α (TNF-α) or other key steps (IL-1, IL-6, T cells, B cells) in the pathogenesis of RA, have given clues to be effective and safe as treatments for RA, being capable of improving disease activity, ameliorating functional ability and halting joint damage. A large body of evidence, stemming from randomized clinical trials, observational studies, and registries, has shown that the beneficial effects of the bDMARDs become optimal when combined with synthetic (s)-DMARDs, mainly methotrexate (MTX). Despite combination therapy is advocated by the international guidelines for the management of RA, data from the daily standard of care indicate that almost one third of RA patients are treated with bDMARDs as monotherapy. Many reasons may be taken into account to explain this gap from official recommendations, among which the fact that in real-life settings, the assessment of clinical outcomes is exclusively based on clinical indices, disregarding the evolution of bone damage. Furthermore, some bDMARDs have been launched in the market with the official approval to be used as monotherapy. But even for the latter, there is no conclusive proof that monotherapy regimen is comparable to co-therapy with MTX in preventing articular damage. In conclusion, the most recent published data show that combination therapy with bDMARDs and MTX represents the best therapeutic option for the treatment of RA since it can stop or at least slow the progression of disabling structural damage.

    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)

    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. PMID:26454049

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

    International Nuclear Information System (INIS)

    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)

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

  8. Long-term results in 144 localized Ewing's sarcoma patients treated with combined therapy

    International Nuclear Information System (INIS)

    The results of 144 previously untreated cases of primary Ewing's sarcoma of bone are reported with a minimum follow-up of 5 years. This series was treated between 1972 and 1982 at Istituto Ortopedico Rizzoli with a combined therapy. The local control of the disease consisted of amputation (ten cases), resection followed by radiation therapy (35-45 Gy) (48 cases) and radiation therapy alone (40-60 Gy) (86 cases). Adjuvant chemotherapy, rigorously standardized, was performed according two different protocols: the first (85 cases treated in the period 1972-1978) consisted of vincristine (VCR) Adriamycin (doxorubicin) (ADM), and cyclophosphamide (EDX); the second (59 cases treated in the period 1979-1982) of VCR, ADM, EDX and dactinomycin (DACT). At a follow-up of 5 to 16 years (median, 9), 59 patients (41%) are continuously disease-free (CDF), 81 (56%) developed metastatic disease and/or local recurrence, and four (3%) had a second malignancy. Three factors seem to be correlated to prognosis: the site of the initial lesion (only 23% of the pelvic lesions are represented in the CDF group versus 46% of the other locations); the chemotherapy protocol (32% of the cases in the first protocol are CDF versus 54% in the second); the type of local treatment (60% of the patients treated with amputation or resection plus radiotherapy versus 28% of those treated with radiation therapy alone are CDF). A local recurrence was observed in 24% of the patients (8% in the group locally treated with surgery or surgery plus radiation therapy versus 36% in the group treated with radiation therapy alone). These data suggest that even though adjuvant chemotherapy can improve the long-term results in localized Ewing's sarcoma patients, this disease still represents, in a high percentage of cases, a lethal process whose final prognosis widely depends on the local control of the lesion

  9. Antitumor bystander effect induced by radiation-inducible target gene therapy combined with α particle irradiation

    International Nuclear Information System (INIS)

    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.

    Polymyxins are last-resort antibiotics for treating infections of Gram-negative bacteria. The recent emergence of polymyxin-resistant bacteria, however, urgently demands clinical optimisation of polymyxin use to minimise further evolution of resistance. In this study we developed a novel combination therapy using minimal concentrations of polymyxin B. After large-scale screening of Streptomyces secondary metabolites, we identified a reliable polymixin synergist and confirmed as netropsin using high-pressure liquid chromatography, nuclear magnetic resonance, and mass spectrometry followed by in vitro assays using various Gram-negative pathogenic bacteria. To evaluate the effectiveness of combining polymixin B and netropsin in vivo, we performed survival analysis on greater wax moth Galleria mellonella infected with colistin-resistant clinical Acinetobacter baumannii isolates as well as Escherichia coli, Shigella flexineri, Salmonella typhimuruim, and Pseudomonas aeruginosa. The survival of infected G. mellonella was significantly higher when treated with polymyxin B and netropsin in combination than when treated with polymyxin B or netropsin alone. We propose a netropsin combination therapy that minimises the use of polymyxin B when treating infections with multidrug resistant Gram-negative bacteria. PMID:27306928

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

  12. Combined chemotherapy and radiation therapy in limited disease small-cell lung cancer

    International Nuclear Information System (INIS)

    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).

    International Nuclear Information System (INIS)

    Introduction: The cancer bone metastases in 40% of patients with advanced breast cancer are detected; osteolysis predominates in 70% of cases, but in 30% osteoblastic component is observed, that gives the possibility for use of strontium-89. Aim: The aim of this study was to evaluate the effectiveness of connected therapy using strontium-89 (osteoblastic component) and pamidronate therapy (osteolytic component) in the group of breast cancer patients with multiple osteoblastic-osteolytic (mixed) bone metastases. Material and methods. 13 patients with breast cancer and multiple bone painful metastases (2 or more) detected by scintigraphy and by radiogram or CT or MRI (character of metastases) were included in the study. All patients have been treated with analgetics (NSAID + opioids). Each patient received 150 MBq of strontium-89 (Metastron, Nycomed-Amersham) combined with intravenous infusion of 60 mg pamidronate (Aredia, Novartis) and short low-dose steroid therapy. The bisphosphonate therapy was repeated every month. For assessment of therapy effectiveness, pain relief (VAS scale), a reduction in analgesic requirements and motor activity (ECOG and Karnofsky scale) were evaluated. The group of 10 patients treated with bisphosphonate only in the same time was observed. Results. During follow-up after 4 weeks and 10 weeks of the end of strontium-89 therapy, we noticed pain relief effects as follows: 'good' (VAS5) in 4 patients. We have observed that the analgesic requirements decreased to 30% of dose on average. The motor activity of the points evaluated increased from 3 to 2 in the ECOG scale and from 40 to 60 in the Karnofsky scale. No pathological fractures, hypercalcaemia and other serious side effects with clinical manifestations were observed. The results of treatment in the group with strontium 89 and bisphosphonate were better than in the group treated with bisphosphonates only (40% 'good' and 'moderate' response rate, one case of pathological fracture

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

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

    X-linked severe combined immunodeficiency (SCID-X1) is a profound deficiency of T, B, and natural killer (NK) cell immunity caused by mutations inIL2RGencoding the common chain (γc) of several interleukin receptors. Gamma-retroviral (γRV) gene therapy of SCID-X1 infants without conditioning restores T cell immunity without B or NK cell correction, but similar treatment fails in older SCID-X1 children. We used a lentiviral gene therapy approach to treat five SCID-X1 patients with persistent immune dysfunction despite haploidentical hematopoietic stem cell (HSC) transplant in infancy. Follow-up data from two older patients demonstrate that lentiviral vector γc transduced autologous HSC gene therapy after nonmyeloablative busulfan conditioning achieves selective expansion of gene-marked T, NK, and B cells, which is associated with sustained restoration of humoral responses to immunization and clinical improvement at 2 to 3 years after treatment. Similar gene marking levels have been achieved in three younger patients, albeit with only 6 to 9 months of follow-up. Lentiviral gene therapy with reduced-intensity conditioning appears safe and can restore humoral immune function to posthaploidentical transplant older patients with SCID-X1. PMID:27099176

    In recent years, magnetic hyperthermia nanoparticles have drawn great attention for cancer therapy because they have no limitation of tissue penetration during the therapy process. In this study, cubic nanoporous Fe2O3 nanoparticles derived from cubic Prussian blue nanoparticles were used as magnetic cores to generate heat by alternating the current magnetic field (AMF) for killing cancer cells. In addition, polypyrrole (PPy) was coated on the surfaces of the cubic Fe2O3 nanoparticles to load doxorubicin hydrochloride (DOX). The PEG component was then physically adsorbed onto the surfaces of the nanoparticles, resulting in a Fe2O3@PPy-DOX-PEG nanocomposite. The nanocomposite was triggered by acid stimulus and AMF to release DOX, resulting in a remarkable combination therapeutic effect via chemotherapy and magnetic hyperthermia. Furthermore, the nanocomposite could realize magnetic resonance imaging (MRI) due to the magnetic core structure. The study provides an alternative for the development of new nanocomposites for combination cancer therapy with MR imaging in vivo.

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

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

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

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

    Full Text Available Abstract Background Diuretics are recommended as initial treatment for hypertension. Several studies have suggested suboptimal persistence and adherence to thiazide diuretic monotherapy; this study compared patient persistence and adherence with hydrochlorothiazide (HCTZ monotherapy to fixed-dose combinations containing HCTZ. Methods Patients with at least one prescription claim during 2001 to 2003 for either HCTZ or one of the following fixed-dose combinations: angiotensin-receptor blockers/HCTZ (ARB/HCTZ, angiotensin-converting enzyme inhibitor/HCTZ (ACEI/HCTZ, or beta blockers/HCTZ (BB/HCTZ were identified. Patients were required to be continuously benefit-eligible six months pre- and one year post-index date, and to have no prescription claims for any antihypertensive therapy six months prior to the index date. Patients were followed for one year to assess persistence, medication possession ratio (MPR, adherence (MPR >80%, and proportion of days covered (PDC with initial antihypertensive therapy. Logistic regression was used to calculate adjusted odds ratios for persistence, adherence and PDC, adjusted for age, gender, business segment, RxRisk disease categories, average co-pay and concurrent cardiovascular-related medication utilization. Results The study cohort consisted of 48,212 patients; 72.5% used HCTZ, 13.2% ACEI/HCTZ, 9.3% ARB/HCTZ, and 5.0% BB/HCTZ. Mean age was 53.7 years and 66.5% were female. A significantly lower proportion of patients using HCTZ (29.9% remained persistent with therapy at 12 months compared with ARB/HCTZ (52.6%; OR = 0.37, CI = 0.36, 0.38, ACEI/HCTZ (51.4%; OR = 0.38, CI = 0.37, 0.39, and BB/HCTZ (51.9%; OR = 0.38, 0.37, 0.40.

    Full Text Available Background. The high rate of epileptic disease spreading determines the need of antiepileptic drugs investigation. Carbamazepine, being one of the most effective anticonvulsant drugs, has a wide spectrum of common side effects, and one of the supposed ways to solve this problem is to combine carbamazepine with nootrops. The possibility of the combined anticonvulsant and nootropic therapy still needs further researches. Objective. To study the efficiency of the combined carbamazepine and nootrops use in the experiment on rats and mice to reduce the side effects of anticonvulsant therapy in the form of impaired cognitive brain function and performance. Methods. The research was conducted on 50 white rats and 30 white mice divided randomly in 5 groups: group 1 received carbamazepine 40mg/kg; group 2 – carbamazepine 40 mg/kg + pyracetam 500 mg/kg; group 3 – carbamazepine 40 mg/kg + citicoline 500 mg/kg; group 4 – carbamazepine 40 mg/kg + memantine 10 mg/kg; group 5 – intact animals (control group. The myorelaxing effects of the therapy, physical working capacity, neurotoxity of the drugs were estimated on the 4th day of nootrops administration and 30 minutes after single carbamazepine administration. Histological examination of the brain specimens was performed; the doses of carbamazepine used in morphological study were 40 mg/kg, 150 mg/kg and 720 mg/kg intragastrally. Results. Administration of carbamazepine occurs moderate morphological changes of brain tissue caused by a reaction on the part of the microvasculature, the severity of which depends on the dose of the drug. Conclusion. The most effective combinations that remove the central side effects of carbamazepine are carbamazepine + gliatilin and carbamazepine + citicoline.

All patients were evaluated at baseline and at the end of the treatment(week 4.The evaluations were performed by using Brunnstrom Staging, Fugl Meyer Motor Function Scale(FM,Barthel Index(BI and goniometric measurement of wrist extension. RESULTS: The Brunnstrom stage(p<0.01, total score on FM and BI scores (p<0.01 were improved at week 4 compared to the baseline, whereas wrist subscore on FM and the goniometric measurements of the wrist and wrist extension were significantly improved only in group II.The two treatment groups were not statistically different in terms of posttreatment evaluation parameters. CONCLUSION: In our study,the mirror therapy combined with conventional rehabilitation program was not superior to conventional rehabilitation program alone in terms of upper extremity motor and functional recovery.

  12. Human Exportin-1 is a Target for Combined Therapy of HIV and AIDS Related Lymphoma

    Full Text Available Infection with HIV ultimately leads to advanced immunodeficiency resulting in an increased incidence of cancer. For example primary effusion lymphoma (PEL is an aggressive non-Hodgkin lymphoma with very poor prognosis that typically affects HIV infected individuals in advanced stages of immunodeficiency. Here we report on the dual anti-HIV and anti-PEL effect of targeting a single process common in both diseases. Inhibition of the exportin-1 (XPO1 mediated nuclear transport by clinical stage orally bioavailable small molecule inhibitors (SINE prevented the nuclear export of the late intron-containing HIV RNA species and consequently potently suppressed viral replication. In contrast, in CRISPR-Cas9 genome edited cells expressing mutant C528S XPO1, viral replication was unaffected upon treatment, clearly demonstrating the anti-XPO1 mechanism of action. At the same time, SINE caused the nuclear accumulation of p53 tumor suppressor protein as well as inhibition of NF-κB activity in PEL cells resulting in cell cycle arrest and effective apoptosis induction. In vivo, oral administration arrested PEL tumor growth in engrafted mice. Our findings provide strong rationale for inhibiting XPO1 as an innovative strategy for the combined anti-retroviral and anti-neoplastic treatment of HIV and PEL and offer perspectives for the treatment of other AIDS-associated cancers and potentially other virus-related malignancies.

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

    Xinji Zhang

    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

    Malaria parasites carrying genes conferring resistance to antimalarials are thought to have a selective advantage which leads to higher rates of transmissibility from the drug-treated host. This is a likely mechanism for the increasing prevalence of parasites with resistance to chloroquine (CQ) and sulfadoxine-pyrimethamine in sub-Saharan Africa. Combination therapy is the key strategy being implemented to reduce the impact of resistance, but its effect on the transmission of genetically resistant parasites from treated patients to mosquito vectors has not been measured directly. In a trial comparing CQ monotherapy to the combination CQ plus artesunate (AS) in Gambian children with uncomplicated falciparum malaria, we measured transmissibility by feeding Anopheles gambiae mosquitoes with blood from 43 gametocyte-positive patients through a membrane. In the CQ-treated group, gametocytes from patients carrying parasites with the CQ resistance-associated allele pfcrt-76T prior to treatment produced infected mosquitoes with 38 times higher Plasmodium falciparum oocyst burdens than mosquitoes fed on gametocytes from patients infected with sensitive parasites (P < 0.001). Gametocytes from parasites carrying the resistance-associated allele pfmdr1-86Y produced 14-fold higher oocyst burdens than gametocytes from patients infected with sensitive parasites (P = 0.011). However, parasites carrying either of these resistance-associated alleles pretreatment were not associated with higher mosquito oocyst burdens in the CQ-AS-treated group. Thus, combination therapy overcomes the transmission advantage enjoyed by drug-resistant parasites. PMID:15388456

  15. Local tumor hyperthermia in combination with radiation therapy. I. Malignant cutaneous lesions

    International Nuclear Information System (INIS)

    There is increasing evidence that the use of hyperthermia alone or in conjunction with other modalities may improve the therapeutic effectiveness of treatment of cancer. The present clinical studies were carried out to evaluate the response of normal and tumor tissues in patients with various cutaneous malignant lesions to repeated courses of hyperthermia alone or in conjunction with radiation therapy. Thirty-six patients with malignant cutaneous lesions (mycosis fungoides, Kaposi sarcoma, malignant melanoma, lymphoma cutis, and other metastatic skin lesions) have been studied. The heating methods used were: temperature regulated water bath immersion; and radiofrequency inductive heating. The normal tissue effects of the combined treatments of radiation and hyperthermia do not appear to be greater than those treated with radiation alone. The initial tumor regression rates were faster in patients treated with radiation plus hyperthermia than in radiation alone, particularly in patients with Kaposi sarcoma and lymphoma cutis. Among ten locally recurrent patients, seven showed significant prolonged benefits achieved by the combined treatments as compared with the radiation therapy alone. Fractionated hyperthermia alone caused significant tumor regression in four out of five patients. Possible mechanisms leading to the improved results from the combined treatments are discussed

  16. Clinical effect observation of 125I seed implantation combined with endocrinal therapy for prostate cancer

    International Nuclear Information System (INIS)

    Objective: To retrospectively study the efficacy and side-effect of 125I seed implantation combined with endocrinal therapy in stage T3N0M0 prostate cancer. Methods: The study included 22 patients with clinical stage T3N0M0 prostate cancer who were treated with transperineal 125I seed implantation guided by transrectal ultrasound, real time TPS and endocrinal therapy. The minimum peripheral doses (MPD) were 140-160 Gy. The median number of seeds was 74(26-90). The activity of each seed was 1.55 × 107 (1.30 × 107-1.85 × 107) Bq. 11 patients were treated with orchidectomy, and 11 patients were treated with androgen deprivation therapy. Results: All 22 patients completed the seed implantation successfully. The 5-year biochemical progression-free survival was 70.6%, and 5-year overall survival was 81.8%. 2 patients were found biochemical failure in 12 months after seed implantation, and another 1 patient failed in 90 months. Endocrinal therapy was followed thereafter. After the seed implantation, the urinary complications of grade 1 and 2 were 54.5% and 9.1% respectively, and the rectum side-effect of grade 1 and 2 were 22.7% and 9.1%.1 patient suffered rectal complication of grade 4. Conclusions: Good effect and tolerance are observed in prostate cancer patients of stage T3N0M0 receiving 125I seed implantation plus endocrinal therapy.The treatment can be considered for those who refuse to receive external beam radiotherapy.

  17. Acute toxicity and efficacy of postoperative combined modality therapy for adenocarcinoma of the pancreas

    International Nuclear Information System (INIS)

    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/m2) 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 Cutaneous melanoma arises from the malignant transformation of skin melanocytes; its incidence and mortality have been increasing steadily over the last fifty-years, now representing 3% of total tumors. Once melanoma metastasizes, prognosis is somber and therapeutic options are limited. However, the discovery of prevalent BRAF mutations in at least 50% of melanoma tumors led to development of BRAF inhibitors, and other drugs targeting the MAPK pathway including MEK inhibitors, are changing this reality. These recently approved treatments for metastatic melanoma have made a significant impact on patient survival; though the results are shadowed by the appearance of drug-resistance. Combination therapies provide a rational strategy to potentiate efficacy and potentially overcome resistance. Undoubtedly, the last decade has also born an renaissance of immunotherapy, and encouraging advances in metastatic melanoma treatment are illuminating the road. Immune checkpoint blockades, such as CTLA-4 antagonist-antibodies, and multiple cancer vaccines are now invaluable arms of anti-tumor therapy. Recent work has brought to light the delicate relationship between tumor biology and the immune system. Host immunity contributes to the antitumor activity of oncogene-targeted inhibitors within a complex network of cytokines and chemokines. Therefore, combining immunotherapy with oncogene-targeted drugs may be the key to melanoma control. Here we review ongoing clinical studies of combination therapies using both oncogene inhibitors and immunotherapeutic strategies in melanoma patients. We will revisit the preclinical evidence that tested sequential and concurrent schemes in suitable animal models and formed the basis for the current trials. Finally, we will discuss potential future directions of the field.

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

  2. Combination therapy of temporary tracheal stenting and radiofrequency ablation for multinodular thyroid goiter with airway compression

    International Nuclear Information System (INIS)

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

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.

    The synthesis of mesoporous silica nanoparticles (MSN) covalently encapsulating fluoresceine or a photosensitizer, functionalized with galactose on the surface is described. Confocal microscopy experiments demonstrated that the uptake of galactose-functionalized MSN by colorectal cancer cells was mediated by galactose receptors leading to the accumulation of the nanoparticles in the endosomal and lysosomal compartments. The MSN functionalized with a photosensitizer and galactose were loaded with the anti-cancer drug camptothecin. Those MSN combining drug delivery and photodynamic therapy were tested on three cancer cell lines and showed a dramatic enhancement of cancer cell death compared to separate treatments.

    Full Text Available Several simple ordinary differential equation (ODE models of tumor growth taking into account the development of its vascular network are discussed. Different biological aspects are considered from the simplest model of Hahnfeldt et al. proposed in 1999 to a model which includes drug resistance of cancer cells to chemotherapy. Some of these models can be used in clinical oncology to optimize antiangiogenic and cytostatic drugs delivery so as to ensure maximum efficacy. Simple models of continuous and periodic protocols of combined therapy are implemented. Discussion on the dynamics of the models and their complexity is presented.

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

  18. Combining vascular and cellular targeting regimens enhances the efficacy of photodynamic therapy

    International Nuclear Information System (INIS)

    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/cm2) 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/cm2) 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

    The main goal of our study was to compare the quality of resulting facials scar 12 weeks after single and combined laser therapy. Forty-one children from age 1.5 to 5 years with facial scars after injury participated in the study. Thirty-one underwent laser therapy, 14 were treated using single low-level laser therapy (670 nm, fluence 3-5 J/cm(-2) ), and 17 underwent combined high-level laser therapy with non-ablative pulsed dye laser (PDL; 595 nm, spot size 7 mm, delay 0.45 ms or 1.5 ms, fluence 9-11 J/cm(-2) , cryogen spray/delay 20/30 ms) and low-level laser therapy. The control group consisted of 10 untreated children. Before treatment and at week 4, 8, and, 12 the scars were evaluated using the POSAS questionnaire. A statistically significant improvement in scars (between ratings before treatment and 4 weeks after therapy, before treatment and 8 weeks after therapy and before treatment and 12 weeks after therapy) was observed in all parameters in both treatment groups (p < 0.0001). For the HLLT+LLLT group the most significant enhancement in the quality of scars was found for all items and at all evaluations, except pigmentation and pliability. There was no improvement observed in quality of facial scars in the control group. PMID:26031491

    Full Text Available Background and objective At present, there is no standard salvage treatment strategies for lung cancer. The aim of this study is to compare the efficacies and safeties of pemetrexed alone with pemetrexed combined with oxaliplatin as salvage therapy in stage IV lung adenocarcinoma to provide evidences for combination therapy. Methods From January 2009 to February 2011, 83 patients with stage IV lung adenocarcinoma received pemetrexed alone (single agent arm, n=47 or pemetrexed combined with oxaliplatin (combination arm, n=36 as salvage therapy. All 83 patients had performance status (PS scores of 0-2. Results Eighty-one patients were included in the final analysis. The median progression-free survival (PFS in the single agent arm was 3.6 months versus 4.1 months in the combination arm (P=0.268. The objective response rate (ORR was 6.5% versus 20% (P=0.092, and the disease control rate (DCR was 56.5% versus 65.7% (P=0.493, respectively. The response rates of the hematological and gastrointestinal toxicities in the single agent and combination arms were 33.9% versus 47.2% (P=0.460 and 21.2% versus 25.0% (P=0.213, respectively. Conclusion For salvage therapy, pemetrexed combined with oxaliplatin is tolerable in stage IV lung adenocarcinoma patients with good PS scores. Compared with pemetrexed alone, pemetrexed combined with oxaliplatin therapy showed higher response rate, but did not significantly prolong the PFS.

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

    Eighty-three patients suffering from moderate or advanced malignant tumors were treated by combined chemotherapy and photodynamic therapy (PDT) in our hospital. The short term result of such management is very promising, the effectiveness seems to be nearly 100% and the general responsive rate is 79.5% (CR + PR). If compared with another group of 84 similar patients whom were treated with PDT alone, the short term efficacy is 85.7% while the general response rate is 54.7% (P statistic. The better result of the combined approach is probably due to the action of the chemotherapeutic agent, potentially blocking the mitosis of the cellular cycle at certain phases of the cancer cells, making the cell membrane become more permeable to the photochemical agent, HPD, and eliciting a better cancerocidal effect.

    Vision loss associated with the idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) syndrome most commonly occurs from macular edema or complications related to neovascularization. The authors present a case of advanced IRVAN associated with a massive exudative response characterized by peripheral retinal telangiectasias, exudative retinal detachment, and macular edema with lipid maculopathy. The patient was managed successfully with visual acuity from hand motion to 20/150 using a combination of local corticosteroids, intravitreal bevacizumab, panretinal photocoagulation, and eventually pars plana vitrectomy for progressive vitreomacular traction. VEGF- and non-VEGF-mediated mechanisms appear to be involved in the pathogenesis of IRVAN given the efficacy of combination therapy. [ophthalmic surg lasers imaging retina. 2013;44:599-602.].

    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.

  8. Internal parameters monitored during intraarterial cytostatic therapy with methotrexate and bleomycin combined with radiotherapy

    International Nuclear Information System (INIS)

    Over a period of ten years, i.e., 1973 to 1983, the Vienna Clinic of Mandibular and Facial Surgery treated 109 patients with primary inoperable malignant tumors using regional chemotherapy, i.e., a combination of methotrexate and bleomycin. 95 patients in the groups were also irradiated. The aim of the internal examinations was to assess whether from the beginning of cytostatic therapy it would be possible to deduct from laboratory chemical examinations some prognostic factors, or whether changes in internal parameters during therapy correspond to the further development of the growth. The examination of chemical parameters showed that the permanently reduced levels of Fe and anemia are demonstrably adverse factors for prognosis. The drop in leukocyte and thrombocyte counts and the toxic damage of bone marrow also proved to be such an adverse factor. On the other hand the rise in serum levels of LDH, AST and ALT in the process of therapy may be assessed as favourable factors for the prognosis of the disease. (author). 1 fig., 12 refs

  9. Intracavitary γ-therapy in combined treatment of cervical cancer with different dose fractionation

    International Nuclear Information System (INIS)

    A cooperative study of comparative assessment of the efficacy of 3 dose fractionation regimes in intracavitary γ-therapy used in combined radiation therapy of cervical cancer is presented (5 Gy, 10 fractions, 2-3 times a week; 7 Gy, 7 fractions, once in 5 days; 10 Gy, 4 fractions, once a week). Over the period of 1979-1983 1193 patients were treated by uniform methods of intracavitary and distant irradiation. The groups were identical with relation to the number of patients, stage of disease, histological characterization and growth type. By the end of therapy the cure rate among 1183 patients was 90-3%. In 2-3 months the cure rate in the same group was 97.5%. Delayed regression was most noticeable in stages I and III. The 5-year survival rates in 3 groups were: for stage I - 95.3±2.6%; for stage II - 83.1±2.5%; for stage III - 73.3±4.7%. In stage I and II tumors the 5-year survival rates in different regiments were similar whereas in stage III better results were obtained with a fractional dose of 5 Gy. The frequency and degree of severity of late radiation complications of the rectum, bladder,vaginal mucous membrane grew with an increase in a fractional dose

    Full Text Available Subhabrata Moitra,1 Arvind B Bhome,2 Bill B Brashier1 1Chest Research Foundation, Pune, Maharashtra, India; 2Indian Coalition of Obstructive Lung Diseases (ICOLD Network, Pune, Maharashtra, India Abstract: The quest for the right combination of bronchodilators with different mechanisms of action such as long-acting muscarinic antagonists and long-acting β-agonists in the management of stable moderate-to-severe chronic obstructive pulmonary disease (COPD is a topic of intense research activity currently, given the rising morbidity and mortality due to this disease. The fixed-dose combination of aclidinium bromide and formoterol fumarate in a single inhaler seems to offer superior advantages over either drugs given alone or as separate inhalers concurrently. Since the fixed-dose combination needs to be given twice daily, it is likely to achieve control of symptoms most crucial to the quality of life in COPD, namely, the morning hours. This is reflected in significant trough FEV1 (forced expiratory volume in 1 second improvements after the dose. This paper reviews the various studies related to this combination put in the perspective of its safety and efficacy and potential benefits over other therapeutic options. However, there is a dearth of data on the long-term safety and efficacy in terms of improvement in lung function. This combination could emerge as an excellent option in the management of stable COPD if data on exacerbation rates and patient-reported outcomes become available from longer-term studies. Moreover, we need some more studies to define the ideal phenotype of COPD best suited for the use of this combination.

    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

    Statins are the frontline in cholesterol reduction therapies; however use in combination with agents that possess complimentary mechanisms of action may achieve further reductions in LDL-C. Thirty-nine patients were treated with either 80mg simvastatin (n=20) or 10mg simvastatin plus 10mg ezetimibe (n=19) for 6 weeks. Dosing was designed to produce comparable LDL-C reductions, while enabling assessment of potential simvastatin-associated pleiotropic effects. Baseline and post-treatment plasma were analyzed for lipid mediators (e.g., eicosanoids, endocannabinoids) and structural lipids by liquid chromatography tandem mass spectrometry. Following statistical analysis and orthogonal projections to latent structures (OPLS) multivariate modeling, no changes were observed in lipid mediator levels, while global structural lipids were reduced in response to both mono- (R2Y=0.74, Q2=0.66, CV-ANOVA p=7.0×10-8) and combination therapy (R2Y=0.67, Q2=0.54, CV-ANOVA p=2.6×10−5). OPLS modeling identified a subset of 12 lipids that classified the two treatment groups after 6 weeks (R2Y=0.65, Q2=0.61, CV-ANOVA p=5.4×10−8). Decreases in the lipid species PC(15:0/18:2) and HexCer(d18:1/24:0) were the strongest discriminators of LDL-C reductions for both treatment groups (q<0.00005), while PE(36:3e) contributed most to distinguishing treatment groups (q=0.017). Shifts in lipid composition were similar for high-dose simvastatin and simvastatin/ezetimibe combination therapy, but the magnitude of the reduction was linked to simvastatin dosage. Simvastatin therapy did not affect circulating levels of lipid mediators, suggesting that pleiotropic effects are not associated with eicosanoid production. Only high-dose simvastatin reduced the relative proportion of sphingomyelin and ceramide to phosphatidylcholine (q=0.008), suggesting a pleiotropic effect previously associated with a reduced risk of cardiovascular disease.

    Episodes of delayed hemolysis 2–6 weeks after treatment of severe malaria with intravenous artesunate have been described. We performed a prospective observational study of patients with uncomplicated malaria to investigate whether posttreatment hemolysis also occurs after oral artemisinin-based combination therapy. Eight of 20 patients with uncomplicated malaria who were given oral artemisinin-based combination therapy met the definition of posttreatment hemolysis (low haptoglobin level and increased lactate dehydrogenase level on day 14). Five patients had hemolysis persisting for 1 month. Patients with posttreatment hemolysis had a median decrease in hemoglobin level of 1.3 g/dL (interquartile range 0.3–2.0 g/dL) in the posttreatment period, and patients without posttreatment hemolysis had a median increase of 0.3 g/dL (IQR −0.1 to 0.7 g/dL; p = 0.002). These findings indicate a need for increased vigilance for hemolytic events in malaria patients, particularly those with predisposing factors for anemia. PMID:27434054

  15. Combination total lymphoid irradiation and low-dose corticosteroid therapy for progressive multiple sclerosis

    International Nuclear Information System (INIS)

    Total lymphoid irradiation (TLI) has been reported to delay deterioration in patients with progressive multiple sclerosis and other autoimmune disorders. Methods - In an open trial, the effect of TLI combined with a one year course of low dose prednisone was compared to the effect of sham TLI and TLI only in a prior double-blind study of patients with progressive multiple sclerosis. Results - Twenty-seven patients receiving TLI combined with corticosteroids had significantly greater lymphocytopenia in the year post-therapy than those receiving TLI only or sham TLI and Kaplan Meier product-limit survival analysis showed significantly less progression in the TLI plus steroid group over 4 years of follow-up. No difference in lymphocytopenia or progression was found with TLI plus corticosteroid therapy when the spleen was removed from the field of irradiation. Conclusion - These results lend further support to the hypothesis that TLI may be effective in progressive MS, and indicates that adding low-dose prednisone may enhance this effect. The study also suggests that TLI may be equally effective whether or not the spleen is irradiated. (au) (14 refs.)

    The efficacy of combination therapy with a "suicide gene" and a cytokine gene to treat metastatic colon carcinoma in the liver was investigated. Tumor in the liver was generated by intrahepatic injection of a colon carcinoma cell line (MCA-26) in syngeneic BALB/c mice. Recombinant adenoviral vectors containing various control and therapeutic genes were injected directly into the solid tumors, followed by treatment with ganciclovir. While the tumors continued to grow in all animals treated with a control vector or a mouse interleukin 2 vector, those treated with a herpes simplex virus thymidine kinase vector, with or without the coadministration of the mouse interleukin 2 vector, exhibited dramatic necrosis and regression. However, only animals treated with both vectors developed an effective systemic antitumoral immunity against challenges of tumorigenic doses of parental tumor cells inoculated at distant sites. The antitumoral immunity was associated with the presence of MCA-26 tumor-specific cytolytic CD8^+ T lymphocytes. The results suggest that combination suicide and cytokine gene therapy in vivo can be a powerful approach for treatment of metastatic colon carcinoma in the liver.

  17. New combined therapy of radiation and local administration of OK-432 for esophageal cancer

    International Nuclear Information System (INIS)

    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)

    Glycyrrhizin has been used clinically for several years due to its beneficial effect on immunoglobulin E (IgE)-induced allergic diseases, alopecia areata and psoriasis. In this study, glycyrrhizin, ultraviolet B light (UVB) or a combination of both were used to treat active-stage generalized vitiligo. One hundred and forty-four patients between the ages of 3 and 48 years were divided into three groups: group A received oral compound glycyrrhizin (OCG); group B received UVB applications twice weekly, and group C received OCG+UVB. Follow-ups were performed at 2, 4, and 6 months after the treatment was initiated. The Vitiligo Area Scoring Index (VASI) and the Vitiligo Disease Activity (VIDA) instrument were used to assess the affected body surface, at each follow-up. Results showed that 77.1, 75.0 and 87.5% in groups A, B and C, respectively, presented repigmentation of lesions. Responsiveness to therapy seemed to be associated with lesion location and patient compliance. Adverse events were limited and transient. This study showed that, although the three treatment protocols had positive results, OCG and UVB combination therapy was the most effective and led to improvement in disease stage from active to stable.

It was confirmed that liposomal CQ can sensitize PTX by means of autophagy inhibition and competitively binding with multidrug-resistance transporters. Furthermore, according to the in vitro cytotoxicity and apoptosis assay, real-time observation of cellular uptake, and in vivo tissue distribution study, co-encapsulation of PTX and CQ in liposomes was validated as superior to the mixture of PTX liposome plus CQ liposome due to the simultaneous delivery and synergetic effect of the two drugs. Consequently, this composite liposome achieved significantly stronger anticancer efficacy in vivo than the PTX liposome plus CQ liposome mixture. This study helps to guide and enlighten ongoing and future clinical trials about the optimal administration modes for drug combination therapy.

    The potential of low molecular weight heparin (LMWH) in anti-angiogenic therapy has been tempered by poor in vivo delivery to the tumor cell and potentially harmful side effects, such as the risk of bleeding due to heparin's anticoagulant activity. In order to overcome these limitations and further improve the therapeutic effect of LMWH, we designed a novel combination nanosystem of LMWH and ursolic acid (UA), which is also an angiogenesis inhibitor for tumor therapy. In this system, an amphiphilic LMWH-UA (LHU) conjugate was synthesized and self-assembled into core/shell nanodrugs with combined anti-angiogenic activity and significantly reduced anticoagulant activity. Furthermore, DSPE-PEG-AA-modified LHU nanodrugs (A-LHU) were developed to facilitate the delivery of nanodrugs to the tumor. The anti-angiogenic activity of A-LHU was investigated both in vitro and in vivo. It was found that A-LHU significantly inhibited the tubular formation of human umbilical vein endothelial cells (HUVECs) (pnanodrugs are a promising multifunctional antitumor drug delivery system.

    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.

    We investigated the combination of near infrared (NIR) photothermolysis and photodynamic therapy against different models of bacteria (S. aureus, S. epidermidis both methicillin susceptible and resistant), in order to discover possible synergistic pathways in the fight against cancer. Photothermolysis was mediated by NIR light absorption from gold nanorods, which were coated with polyethylene glycol to gain biocompatibility and provide for a convenient interface with the bacterial cell walls. At the same time photodynamic therapy was delivered by administration of Indocyanine Green (ICG), whose spectrum of molecular excitation overlaps the plasmonic oscillations of gold nanorods (~ 800 nm). Therefore irradiation with NIR light from a low power diode laser resulted into simultaneous photothermolysis and generation of reactive oxygen species and cytotoxic byproducts of ICG. We assessed the inhibition of the bacterial colony forming ability under different NIR light exposures, and compared the performance of the combined treatment (gold nanorods plus ICG) with the projected addition of the separate treatments (either gold nanorods or ICG). Our preliminary results may originate from the interplay of synergistic and conflicting interactions, which may include e.g. the enhanced intake of cytotoxic species due to permeabilization of the bacterial cell walls, quenching of ICG and modification of the bleaching of ICG due to the noble metal surface.

  6. Kyphoplasty combined with intraoperative radiotherapy (Kypho-IORT). Alternative therapy for patients with oligometastatic spinal metastases

    International Nuclear Information System (INIS)

    Due to a more effective systemic therapy the survival of patients suffering from malignant tumors has been significantly improved but a longer life span is often associated with a higher incidence of osseous metastases. The majority of these metastases are localized in the spine causing pain, instability and neurological impairments. The interdisciplinary management of spinal metastases previously consisted of stabilization followed by fractionated external body radiation therapy. A reduction in procedural severity and morbidity as well as consideration of self-sufficiency and hospitalization time are important target parameters for these palliative patients. Kyphoplasty combined with intraoperative radiotherapy (Kypho-IORT) is one of several modern treatment options, which involves a minimally invasive procedure with local high-dose transpedicular irradiation of the spine with low-energy (50 kV) X-rays. Immediately following irradiation, stabilization of the spine is carried out using kyphoplasty via the same access route so that a single stage procedure with excellent pain reduction and good local tumor control can be achieved. This article presents clinical data for this procedure and the different fields of indications are critically reviewed and compared to other therapy options. Methodological improvements and options for further individualization of therapy are demonstrated. The Kypho-IORT procedure is a safe, feasible and beneficial modern treatment option for instant stabilization and local tumor control in patients with spinal metastases. More than 100 operations have been successfully performed so that the method can be deemed suitable for inclusion in the clinical routine. A phase II dose escalation study has now been completed and submitted for publication and a 2-arm non-inferiority trial (phase III study) for comparison with conventional irradiation is in progress.

    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

  8. Spatiotemporally synchronized cancer combination therapy using photo-activated nanoparticle drug delivery systems (Conference Presentation)

    Science.gov (United States)

    Hasan, Tayyaba

    2016-03-01

    This talk will introduce a new nanotechnology platform for cancer combination therapy that utilizes near infrared light activation not only for photodynamic damage but also as an extrinsic mechanism to initiate release of complimentary drugs to suppress dynamic bursts in molecular signaling networks that promote tumor cell survival and treatment escape. The goal is to achieve co-delivery with concomitant activity of photodynamic, molecular inhibitor and chemotherapeutic agents, selectively within the tumor. This approach overcomes challenges in achieving synergistic interactions using sequential drug delivery. Conventional drug delivery is compromised by the differential pharmacokinetics of individual agents and potentially antagonistic effects—such as vascular shutdown by one agent that limits delivery of the second. Here, photodynamic damage—which efficiently kills drug-resistant cells via damage of common proteins involved in drug-resistance (such as anti-apoptosis factors and drug-efflux transporters)—is synchronized spatially and temporally with the photo-initiated release of complimentary agents—to enable full interaction amongst the individual therapies. This spatiotemporal synchronization offers new prospects for exploiting time-sensitive synergistic interactions. Specific implementations of these concepts will be presented in preclinical models of cancer. Strategies to enable molecular-targeting of cancer cells via site-specific attachment of targeting moieties to the outer lipid shell of these nanovehicles will also be discussed. If successful in humans, this new paradigm for synchronized, tumor-focused combination therapy will ultimately supersede the present use of chronic drug injection by increasing efficacy per cycle whilst reducing systemic exposure to toxic drugs.

  9. The role of bleomycin combination in radiation therapy for squamous cell carcinoma in the oral cavity

    International Nuclear Information System (INIS)

    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)

    [Purpose] Systemic lupus erythematosus (SLE) is a chronic, immune-mediated disease, affecting 0.1% of the general population. To date, few studies have investigated the efficacy of physical therapy for SLE patients with CNS involvement. The aim of this study was to report whether the combined use of corticosteroids and physical therapy, consisting of reflex inhibition and functional training, was beneficial to functional recovery. [Subjects and Methods] A 22-year-old male SLE patient with CNS involvement requested physical therapy due to strong spasticity of the trunk and limbs in a bedridden state. Corticosteroid intervention and physical therapy were undertaken for 16 days. [Result] After 16 days of the interventions, the patient demonstrated stabilized and alleviated neurological symptoms and an improved functional level. [Conclusion] The present case indicates that physical therapy combined with corticosteroids might be a possible treatment and rehabilitation method to effectively recover motor function for SLE patients who have strong spasticity due to CNS involvement.

    Posttraumatic stress disorder (PTSD) and smoking are often comorbid, and both problems are in need of improved access to evidence-based treatment. The combined approach could address two high-priority problems and increase patient access to both treatments, but research is needed to determine whether this is feasible and has promise for addressing both PTSD and smoking. We collected data from 15 test cases that received a treatment combining two evidence-based treatments: cognitive processing therapy-cognitive version (CPT-C) for PTSD and integrated care for smoking cessation (ICSC). We explored two combined treatment protocols including a brief (six-session) CPT-C with five follow-up in-person sessions focused on smoking cessation (n=9) and a full 12-session CPT-C protocol with ICSC (n=6). The combined interventions were feasible and acceptable to patients with PTSD making a quit attempt. Initial positive benefits of the combined treatments were observed. The six-session dose of CPT-C and smoking cessation resulted in 6-month bioverified smoking abstinence in two of nine participants, with clinically meaningful PTSD symptom reduction in three of nine participants. In the second cohort (full CPT-C and smoking treatment), both smoking and PTSD symptoms were improved, with three of six participants abstinent from smoking and four of six participants reporting clinically meaningful reduction in PTSD symptoms. Results suggested that individuals with PTSD who smoke are willing to engage in concurrent treatment of these problems and that combined treatment is feasible. PMID:26763497

    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

    The identification of key driver mutations in melanoma has led to the development of targeted therapies aimed at BRAF and MEK, but responses are often limited in duration. There is growing evidence that MAPK pathway activation impairs antitumor immunity and that targeting this pathway may enhance responses to immunotherapies. There is also evidence that immune mechanisms of resistance to targeted therapy exist, providing the rationale for combining targeted therapy with immunotherapy. Preclinical studies have demonstrated synergy in combining these strategies, and combination clinical trials are ongoing. It is, however, becoming clear that additional translational studies are needed to better understand toxicity, proper timing, and sequence of therapy, as well as the utility of multidrug regimens and effects of other targeted agents on antitumor immunity. Insights gained through translational research in preclinical models and clinical studies will provide mechanistic insight into therapeutic response and resistance and help devise rational strategies to enhance therapeutic responses.

    This study focuses on the co-engineering of salbutamol sulphate (SS), a common bronchodilator, and mannitol (MA), a mucolytic, as a potential combination therapy for mucus hypersecretion. This combination was chosen to have a synergic effect on the airways: the SS will act on the β2-receptor for relaxation of smooth muscle and enhancement of ciliary beat frequency, whilst mannitol will improve the fluidity of mucus, consequently enhancing its clearance from the lung. A series of co-spray-dried samples, containing therapeutically relevant doses of SS and MA, were prepared. The physico-chemical characteristics of the formulations were evaluated in terms of size distribution, morphology, thermal and moisture response and aerosol performance. Additionally, the formulations were evaluated for their effects on cell viability and transport across air interface Calu-3 bronchial epithelial cells, contractibility effects on bronchial smooth muscle cells and cilia beat activity using ciliated nasal epithelial cells in vitro. The formulations demonstrated size distributions and aerosol performance suitable for inhalation therapy. Transport studies revealed that the MA component of the formulation enhanced penetration of SS across the complex mucus layer and the lung epithelia cells. Furthermore, the formulation in the ratios of SS 10(-6) and MA 10(-3) M gave a significant increase in cilia beat frequency whilst simultaneously preventing smooth muscle contraction associated with mannitol administration. These studies have established that co-spray dried combination formulations of MA and SS can be successfully prepared with limited toxicity, good aerosol performance and the ability to increase ciliary beat frequency for improving the mucociliary clearance in patients suffering from hyper-secretory diseases, whilst simultaneously acting on the underlying smooth muscle.

    AIM: To evaluate whether combination therapy with anti-tumour necrosis factor α (TNFα). Zantibody and Zn acetate is beneficial in dextran sodium sulphate(DSS) colitis. METHODS: Colitis was induced in CD1-Swiss mice with 5% DS for 7 d. The exp erimental mice were th en randomised into the following subgroups: standard diet + DSS treated (induced colitis group); standard diet + DSS + subcutaneous 25. Μg anti-TNFα treated group; Zn acetate treated group + DSS + subcutaneous 25 μg anti-TNFα; standard diet + DS + subcut aneou s 6.25 μg anti-TNFα treated group and Zn acetate treated group + DS + subcut aneou s 6.25 μg anti-TNFα. Each group of mice was matched with a similar group of sham contro l animals. Macro scop ic and histo logical featur es were scor ed blindly. Homo genates of th e colonic mu cosa were assessed for myeloperoxidase activity as a biochemical marker of inflamm ation and DNA addu cts (8OHdG) as a measur e of ox idative damage. RESULTS: DSS produced submucosal erosions, ulcers, inflammatory cell infiltration and cryptic abscesses which were reduced in both groups of mice receiving either anti-TNFα alone or com bined with zinc. The effect was more pronounced in the latter group. .(vs Zn diet, P < 0.02).Myeloperoxidase activity (vs controls, P < 0.02) and DNA addu cts, greatly elevated in th e DSS fed colitis group (vs controls,. P < 0.05), were significantly redu ced in th e tr eated group s, with a mor e remarkable effect in the group receiving combined therapy (vs standard diet,. P < 0.04). CONCLUSION: DSS induces colonic inflammation which is modulated by the administration of anti-TNFα. Combining anti-TNFα Zwith Zn acetate offers marginal benefit in colitis severity.

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

  1. Potential benefits of combining cytosine deaminase/5-fluorocytosine gene therapy and irradiation for prostate cancer. Experimental study

    International Nuclear Information System (INIS)

    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)

    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. Da eine Therapie mit BRAF-Inhibitoren bei Patienten mit V600-mutierten Melanomen hoch effektiv ist, sollte man sie waehrend einer Strahlentherapie nicht unterbrechen. Daher ist eine Strahlentherapie unter laufender Behandlung mit

    Purpose: The outcome of radiotherapy can be further improved by combining irradiation with dose enhancers such as high-Z nanoparticles. Since 2004, spectacular results have been obtained when low-energy x-ray irradiations have been combined with nanoparticles. Recently, the same combination has been explored in hadron therapy. In vitro studies have shown a significant amplification of the biological damage in tumor cells charged with nanoparticles and irradiated with fast ions. This has been attributed to the increase in the ionizations and electron emissions induced by the incident ions or the electrons in the secondary tracks on the high-Z atoms, resulting in a local energy deposition enhancement. However, this subject is still a matter of controversy. Within this context, the main goal of the authors’ work was to provide new insights into the dose enhancement effects of nanoparticles in proton therapy. Methods: For this purpose, Monte Carlo calculations (GATE/GEANT4 code) were performed. In particular, the GEANT4-DNA toolkit, which allows the modeling of early biological damages induced by ionizing radiation at the DNA scale, was used. The nanometric radial energy distributions around the nanoparticle were studied, and the processes (such as Auger deexcitation or dissociative electron attachment) participating in the dose deposition of proton therapy treatments in the presence of nanoparticles were evaluated. It has been reported that the architecture of Monte Carlo calculations plays a crucial role in the assessment of nanoparticle dose enhancement and that it may introduce a bias in the results or amplify the possible final dose enhancement. Thus, a dosimetric study of different cases was performed, considering Au and Gd nanoparticles, several nanoparticle sizes (from 4 to 50 nm), and several beam configurations (source-nanoparticle distances and source sizes). Results: This Monte Carlo study shows the influence of the simulations’ parameters on the local

    The development of non-chemotherapeutic agents, including monoclonal antibodies (mAbs) and other targeted drugs, makes chemotherapy-free treatment an attractive option for chronic lymphocytic leukemia (CLL). The classical mAb, rituximab, has been authorized for use in both first-line and second-line therapy for CLL. New mAbs directed against CD20, ofatumumab, and obinutuzumab (GA-101) have also been approved for the treatment of this disease. Recently, several new mAbs with potential benefits over the approved anti-CD20 antibodies have been developed for use in CLL. Anti-CD37, anti-CD19, and anti-CD40 mAbs are in early clinical trials and show promise in treating CLL. In addition, the combination of mAbs with B-cell receptor signaling pathway inhibitors and immunomodulatory drugs makes the chemotherapy-free option a reality today. Combinations of antibodies with targeted drugs like ibrutinib, idelalisib, or lenalidomide are expected to replace chemotherapy-based combinations for treating CLL in the near future. However, phase III trials should confirm the benefit of these new treatment strategies and establish their exact place in the therapeutic armamentarium for CLL. PMID:27040707

    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.

    The SAPHO syndrome represents a variety of clinically similar disorders with the key features of hyperostotic bone lesions in combination with chronic pustular skin disease. The respective pathophysiology of bone and joint manifestations in SAPHO syndrome is still a matter of discussion. For example it does not appear to represent reactive arthritis and HLA B27 antigen, with the latter being typically present in patients with spondyloarthopathies. Treatment of SAPHO syndrome is also not well established and consists of various antiinflammatory and antirheumatic drugs. Here, we report a female patient with active SAPHO syndrome suffering from sternal swelling of unknown origin that had been known for 10 years and a 4-year-history of severe lower back pain. Remarkable were also a typical pustulous palmar erythema associated with swelling and decreased motility of both MCP-I joints. Inflammation parameters were high with an ESR 68 mm/1st hour and a CRP of 19.6 mg/l. She was initially treated with rofecoxib and doxycycline, followed by sulfasalazine with only partial clinical response. Thereafter, both articular symptoms as well as cutaneous lesions responded well to a combination therapy with methotrexate and sulfasalazine. Thus, the case illustrates nicely that methotrexate in combination with another DMARD can be successfully applied to patients with long-term active SAPHO syndrome. PMID:19471601

    AIM: To evaluate the effects of bowel rehabilitation and combined trophic therapy on intestinal adaptation in short bowel patients.METHODS: Thirty-eight patients with severe short-bowel syndrome (SBS) were employed in the present study, whose average length of jejunum-ileum was 35.8±21.2 cm. The TPN treatment was initiated early to attain positive nitrogen balance and prevent severe weight loss. The TPN composition was designated to be individualized and altered when necessary. Enteral feeding was given as soon as possible after resection and increased gradually. Meals were distributed throughout the day. Eight patients received treatment of growth hormone (0.14 mg/kg.day) and glutamine (0.3 g/kg.day) for 3 weeks. D-xylose test, 15N-Gly trace test and 13C-palmitic acid breath test were done to determine the patients' absorption capability.RESULTS: Thirty-three patients maintained well body weight and serum albumin concentration. The average time of follow-up for 33 survival patients was 5.9±4.3 years.Twenty-two patients weaned from TPN with an average TPN time of 9.5±6.6 months. Two patients, whose whole small bowel, ascending and transverse colon were resected received home TPN. An other 9 patients received parenteral or enteral nutritional support partly as well as oral diet. Three week rhGH+GLN therapy increased nutrients absorption but the effects were transient.CONCLUSION: By rehabilitation therapy, most short bowel patients could wean from parenteral nutrition. Dietary manipulation is an integral part of the treatment of SBS.Treatment with growth hormone and glutamine may increase nutrients absorption but the effects are not sustained beyond the treatment period.

  18. The Efficacy and Safety of Entecavir and Interferon Combination Therapy for Chronic Hepatitis B Virus Infection: A Meta-Analysis.

    Full Text Available The objective of this study was to evaluate the effectiveness and safety of entecavir (ETV and interferon (IFN combination therapy in the treatment of chronic hepatitis B (CHB mono-infection via a meta-analysis of randomized controlled trials (RCTs. All eligible RCTs evaluating combination therapy for treating CHB were identified from nine electronic databases. A meta-analysis was performed in accordance with the Cochrane Systemic Review handbook. Eleven trials encompassing 1010 participants were included in this meta-analysis. It showed that at 12 and ≥ 96 weeks of therapy, the combination of ETV and IFN was not better than ETV in improving the undetectable HBV DNA (12 weeks: RR=1.12, 95% CI=0.88-1.42; ≥ 96 weeks: RR = 0.64, 95% CI=0.21-1.98, respectively and HBeAg seroconversion rates (12 weeks: RR=1.35, 95% CI=0.60-3.04; ≥ 96 weeks: RR=1.36, 95% CI=0.75-2.64, respectively. But at 48 weeks of therapy and approximately 2 years of follow up, combination therapy was superior to ETV in improving the undetectable HBV DNA (48 weeks: RR=1.46, 95% CI=1.13-1.90; follow up: RR=2.20, 95% CI=1.26-3.81, respectively and HBeAg seroconversion rates (48 weeks: RR=1.82, 95% CI=1.44-2.30; follow up: RR=1.92, 95% CI=1.19-3.11, respectively. When compared to IFN group, at 24 and 48 weeks of therapy, combination group showed a greater undetectable HBV DNA (24 weeks: RR=2.14, 95% CI=1.59-2.89; 48 weeks: RR=2.28, 95% CI=1.54-3.37, respectively and ALT normalization rate (24 weeks: RR=1.56, 95% CI= 1.24-1.96; 48 weeks: RR=1.55, 95% CI = 1.16-2.07, respectively. At 48 weeks of therapy, combination group achieved a greater HBeAg seroconversion rate than IFN (48 weeks: RR=1.58, 95% CI=1.24-2.00. No significant differences were observed in the side effects of the three therapies. So we can conclude that ETV and IFN combination therapy is more effective than ETV or IFN mono-therapy in CHB treatment. ETV, IFN, and the combination of the two are safe in CHB treatment.

  19. Combination therapy with a nucleos(t)ide analogue and interferon for chronic hepatitis B: simultaneous or sequential.

    Currently available antiviral treatment for chronic hepatitis B virus infection can be divided into two classes of therapeutic agents: nucleos(t)ide analogues (NAs) and interferon (IFN). The major advantages of NAs are good tolerance and potent antiviral activity associated with high rates of on-treatment response to therapy; the advantages of IFN include a finite course of treatment, absence of drug resistance, and an opportunity to obtain a post-treatment durable response to therapy. The use of these two antiviral agents with different mechanisms of action in combination is theoretically an attractive approach for treatment. Here, we have reviewed previous reports of either simultaneous or sequential combination therapy with NA and IFN for chronic hepatitis B patients. In previous studies comparing the lamivudine/IFN combination and lamivudine monotherapy in a finite course, combination therapy was associated with higher rates of sustained post-treatment response and lower rates of drug resistance than lamivudine monotherapy. However, NAs such as lamivudine are generally administered indefinitely because of high rates of post-treatment relapse. In addition, concern for drug resistance has decreased significantly with newer, high-potency NAs even when administered alone. In previous studies comparing the lamivudine/IFN combination and IFN monotherapy, the combination therapy showed greater on-treatment viral suppression, but no difference was observed in the post-treatment sustained response. Thus, whether combination therapy confers an additional benefit compared to monotherapy for treating chronic hepatitis B remains unclear. The efficacy of IFN in combination with a more potent NA, such as entecavir or tenofovir, remains to be comprehensively evaluated. PMID:23338486

    Despite the rise in popularity of both acupuncture and manual therapy in veterinary medicine, and the increasing number of Canadian veterinarians practising these techniques, there is little research demonstrating their effectiveness. In this repeated measures, therapeutic trial, 47 client-owned dogs with naturally occurring lameness were assessed for clinical response to treatment. Owners were blinded to the treatment schedule and completed questionnaires to assess their dogs' comfort and mobility. Comparison between pre- and post-treatment results demonstrated that combined acupuncture and manual therapy provides immediate short-term improvement in comfort and mobility, as demonstrated by owner observed changes in play behavior (P = 0.015), walking (P trotting (P = 0.002), jumping (P < 0.001), descending stairs (P = 0.003), rising from a lying position (P < 0.001), and reduced stiffness after rest (P < 0.001) or following exercise (P < 0.001). Mood and attitude also improved, but did not attain statistical significance. PMID:27041759

  1. Use of hyaluronic acid preparations in the combination therapy of osteoarthritis

    2016-01-01

    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.

    Full Text Available CONTEXT: The treatment of Chagas' disease colopathy is limited to clinical management in the initial of the process, and for patients for whom surgery is not indicated or is not possible, anti-constipation diets are used, along with judicious administration of laxatives and enemas. OBJECTIVE: To evaluate over time the effects of physical-therapy interventions combined with daily ingestion of a laxative fruit drink in the treatment of chagasic megacolon. METHOD: In a quantitative, prospective, and comparative study, 12 patients of both sexes and with a mean age of 67 ± 12 years were clinically evaluated to receive 12 sessions of physical therapy twice a week, along with fruit drink, and were evaluated for intestinal constipation before and after treatment. RESULTS: A significant difference (P0.05. CONCLUSION: The proposed protocol is easy to implement, safe, non-invasive, and low-cost, with the potential to be deployed in health care by providing benefits independent of gender, age, or whether the participant has undergone surgery, improving the condition of patients with chagasic megacolon.

    The introduction of potent combination antiretroviral therapy (cART) has had a remarkable impact on the natural history of HIV infection, leading to a dramatic decline in the mortality rate and a considerable increase in the life expectancy of HIV-positive people. However, cART use is frequently associated with several metabolic complications, mostly represented by lipid metabolism alterations, which are reported very frequently among persons treated with antiretroviral agents. In particular, hyperlipidaemia occurs in up to 70%-80% of HIV-positive subjects receiving cART and is mainly associated with specific antiretroviral drugs belonging to three classes of antiretroviral agents: NRTIs, NNRTIs and PIs. The potential long-term consequences of cART-associated dyslipidaemia are not completely understood, but an increased risk of premature coronary heart disease has been reported in HIV-infected patients on cART, so prompt correction of lipid metabolism abnormalities is mandatory in this population. Dietary changes, regular aerobic exercise and switching to a different antiretroviral regimen associated with a more favourable metabolic profile are the first steps in clinical management, but lipid-lowering therapy with fibrates or statins is often required. In this case, the choice of hypolipidaemic drugs should take into account the potential pharmacokinetic interactions with many antiretroviral agents. PMID:26846208

    A multifunctional organic-inorganic hybrid nanocapsule based on Bi2S3-embedded poly (lactic-co-glycolic acid) (PLGA) nanocapsule has been elaborately designed to combine the merits of both polymeric shell structure and Bi2S3 nanoparticles. Hydrophobic Bi2S3 nanoparticles were successfully introduced into the PLGA nanocapsules via a facile and efficient water/oil/water (W/O/W) emulsion strategy. The elastic polymeric PLGA shell provides the excellent capability of ultrasound contrast imaging to the Bi2S3/PLGA. Meanwhile, the potential of these microcapsules to enhance the high intensity focused ultrasound (HIFU) therapy was demonstrated. Importantly, this research provided the first example of both in vitro and in vivo to demonstrate the radiosensitization effect of Bi2S3-embedded PLGA hybrid nanocapsules against prostate cancer under external X-ray irradiation. Thus, the successful integration of the Bi2S3 and PLGA nanocapsules provided an alternative strategy for the highly efficient ultrasound guided HIFU/RT synergistic therapy. PMID:24973300

    Introduction Some antiretroviral therapy naïve patients starting combination antiretroviral therapy (cART) experience a limited CD4 count rise despite virological suppression, or vice versa. We assessed the prevalence and determinants of discordant treatment responses in a Rwandan cohort. Methods A discordant immunological cART response was defined as an increase of health facilities in two regions in Rwanda. Results Among 382 patients with an undetectable VL at 12 months, 112 (29%) had a CD4 rise of travel to the clinic were independent determinants of an immunological discordant response, but sex, baseline CD4 count, body mass index and WHO HIV clinical stage were not. Among 326 patients with a CD4 rise of ≥100 cells/mm3, 56 (17%) had a detectable viral load at 12 months. Male sex was associated with a virological discordant treatment response (P = 0.05), but age, baseline CD4 count, BMI, WHO HIV clinical stage, and travel time to the clinic were not. Conclusions Discordant treatment responses were common in cART-naïve HIV patients in Rwanda. Small CD4 increases could be misinterpreted as a (virological) treatment failure and lead to unnecessary treatment changes. PMID:27438000

    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.

    2006-01-01

    BACKGROUND: Changes in virologic response to initial combination antiretroviral therapy (cART) over calendar time may indicate improvements in cART or emergence of primary resistance. Regional variations may identify differences in available antiretroviral drugs or patient management. METHODS......: Virologic response (viral load < 500 copies/mL) 6 to 12 months after starting cART was analyzed in antiretroviral-naive EuroSIDA patients. Analyses were stratified by region (south, central west, north, east) or time started cART (early, 1996-1997; mid, 1998-1999; late, 2000-1904). RESULTS: Virologic...... time (P < 0.001) on virologic response after adjustment for confounders. Stratified by period, regional differences were less evident (early cART, P = 0.967; mid cART, P = 0.291; late cART, P = 0.163). Stratified by region, temporal changes were observed (south, P = 0.061; central west, P < 0...

    BACKGROUND: Combination antiretroviral therapy (cART) may vary in ability to suppress viral load and increase CD4+ T-cell count in people infected with different HIV-1 subtypes, possibly due to differences in resistance development. Antiretroviral drugs have predominantly been developed in Western...... Europe/North America on the basis of the most prevalent subtype, B. However, non-B subtypes are increasingly spreading worldwide. OBJECTIVE: To compare virological and immunological response to cART between patients infected with B and non-B subtypes across Europe. DESIGN: EuroSIDA prospective......, observational cohort with 11,928 HIV-1-infected patients. METHODS: Response to cART was analysed in patients with subtypes determined pre-cART, via multivariable logistic regression on the first measurements 6–12 months after starting cART.

    A 31-year-old female who had well-established polycythemia vera one year before, presented with the sudden onset. She had severe ascites and hepatic encephalopathy 12 d prior to admission. Real-time ultrasonography revealed a supra hepatic thrombosis extending toward the inferior vena cava (IVC).Thrombolytic therapy with systemic streptokinase (250000 IU loading + 100000 IU/h infusion) was started. At the end of 72 h infusion, the patient's general condition improved. A color Doppler ultrasonography then showed complete and partial resolution of the thrombosis in the supra hepatic vein and IVC,respectively. Despite this good response, 12 d later, the symptoms recurred. Venography detected complete obstruction of the IVC. Percutanous balloon angioplasty with stent insertion was performed successfully and the patient was discharged without any evidence of liver disease. A combination of systemic streptokinase and radiological intervention was effective in our patient.

    Full Text Available Over 90 per cent of HIV infected babies were born to HIV positive mothers in Sub-Saharan Africa and worldwide. It is estimated that currently 2.3 million i.e 5.9% are children less than 15 yrs of age infected with HIV. Worldwide, children under age 15 who were newly infected with HIV, more than 90 percent were babies were born to HIV-positive women. An estimated 1500 children get newly infected with HIV each day globally. The scenario is similar at home in Andhra Pradesh, India. This present exploratory study is to find out the effectiveness of fixed drug combination of antiretroviral therapy in children. The results are encouraging and are similar to results from such studies elsewhere.

  12. Combined Néel and Brown rotational Langevin dynamics in magnetic particle imaging, sensing, and therapy

    International Nuclear Information System (INIS)

    Magnetic nanoparticles have been studied intensely because of their possible uses in biomedical applications. Biosensing using the rotational freedom of particles has been used to detect biomarkers for cancer, hyperthermia therapy has been used to treat tumors, and magnetic particle imaging is a promising new imaging modality that can spatially resolve the concentration of nanoparticles. There are two mechanisms by which the magnetization of a nanoparticle can rotate, a fact that poses a challenge for applications that rely on precisely one mechanism. The challenge is exacerbated by the high sensitivity of the dominant mechanism to applied fields. Here, we demonstrate stochastic Langevin equation simulations for the combined rotation in magnetic nanoparticles exposed to oscillating applied fields typical to these applications to both highlight the existing relevant theory and quantify which mechanism should occur in various parameter ranges

  14. Cell-targeted 114Inm and drug (BCNU) combination therapy in a rat acute lymphoblastic leukaemia

    International Nuclear Information System (INIS)

    A proportion of syngeneic female rats inoculated intramuscularly with a lethal T-cell lymphoblastic (Roser) leukaemia are cured by a single intraperitoneal injection of bischloroethylnitrosourea (BCNU) (Carmustine)(10 mg kg-1) given towards the end of the preleukaemic phase (day 7). Additional therapy on day 4, using intravenous leukaemia cells lethally labelled with the radionuclide 114Inm, enhanced the overall cure rate by 30%. The spleen is a major site of indium concentration from the targeting cells so that the continuous local radiation field appears to result in a substantial reduction of the body load of leukaemia cells in the enlarged spleen particularly, thus enhancing the curative potential of the drug. The results demonstrate in principle that in patients in remission a single dose of targeted radiotherapy in the spleen combined sequentially with an appropriate drug might provide considerable aid in eliminating a residual population of leukaemia cells.

    Full Text Available Pulmonary alveolar proteinosis (PAP is an orphan disease characterized by the accumulation of excess of surfactant within alveoli and bronchioles. The primary form of PAP (P-PAP; also referred to as idiopathic or autoimmune is the most common form. It is mediated through a circulating neutralizing antibody against granulocyte-macrophage colony-stimulating factor. Secondary PAP (S-PAP can be induced by a host of inciting agents and is far more liable to progress to terminal respiratory failure. We describe a rare case of S-PAP occurring in a renal transplant recipient due to mycophenolate and cyclosporine combination-therapy, which resolved spontaneously following withdrawal of these drugs.

  16. Parenteral nutrition in radiation therapy and combined treatment of patients with esophageal cancer

    International Nuclear Information System (INIS)

    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

    2007-10-01

    Babesia gibsoni is a protozoan parasite of dogs worldwide yet both an effective treatment and a reliable method for detecting subclinical cases of this emerging infection remain elusive. Experimental B. gibsoni infections were established in vivo to investigate the efficacy of combined atovaquone and azithromycin drug therapy and to determine the detection limits of a nested-PCR, IFAT and microscopy during various stages of infection. While atovaquone and azithromycin produced a reduction in parasitaemia, it did not eliminate the parasite and drug resistance appeared to develop in one dog. Polymerase chain reaction was found to be most useful in detecting infection in the pre-acute and acute stages, while IFAT was most reliable during chronic infections. Microscopy is suggested to be only effective for detecting acute stage infections. This study also describes the detection of B. gibsoni in tissue samples during chronic infections for the first time, suggesting possible sequestration of this parasite. PMID:17543304

There are two mechanisms by which the magnetization of a nanoparticle can rotate, a fact that poses a challenge for applications that rely on precisely one mechanism. The challenge is exacerbated by the high sensitivity of the dominant mechanism to applied fields. Here, we demonstrate stochastic Langevin equation simulations for the combined rotation in magnetic nanoparticles exposed to oscillating applied fields typical to these applications to both highlight the existing relevant theory and quantify which mechanism should occur in various parameter ranges.

    Under the influence of electric pulses cells undergo membrane electroporation (EP), which results in increased permeability of the membrane to exogenous compounds. EP is applied in oncology as a method to enhance delivery of anticancer drugs. For that reason it was essential to combine photodynamic...... 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...... dose of 50 microg/ml. Immediately after adding of photosensitizers the cells were electroporated with 8 electric pulses at 1200 V/cm intensity, 0.1 ms duration, 1 Hz frequency. Then, after 20 min of incubation the cells were irradiated using a light source--a visible light passing through a filter (KC...

    Although blood pressure control is crucial in patients with hypertension, current clinical practice guidelines recommend that the goal of treatment should be aimed at not only reducing blood pressure values but decreasing global cardiovascular risk. Available data suggest that blood pressure and LDL-cholesterol control rates, two of the most common cardiovascular risk factors, are low, not only in the primary care setting but also in specialists setting. Clinical trials, such as the Anglo-Scandanavian Cardiac Outcomes Trial (ASCOT), have demonstrated that the integration of a multifactorial approach through the treatment of different risk factors effectively reduces the risk of cardiovascular morbidity and mortality. The aim of this review was to update the current knowledge about the combined therapy of different risk factors in the hypertensive population. PMID:20359702
