    To compare two regimens of reduced bowel preparation and faecal tagging for CT colonography. Single centre, prospective, randomized, noninferiority study, in which 52 consecutive adults underwent routine CT colonography. Patients, following a three-day low-fibre diet, received one of the two reduced preparations: 1-L polyethylene glycol and four tablets of bisacodyl in association with 90 mL of Iopamidol for faecal tagging administered on the same day as CTC examination (group 1); or a standard ''iodine-only'' preparation, consisting in 180 ml of Iopamidol the day before the examination (group 2). Primary outcome was the overall quality of bowel preparation. Twenty-six patients per group were included. Per segment analysis showed preparation of diagnostic quality in 97.4 % of segments in group 1 and in 95.5 % in group 2 (p = ns). Per-patient analysis showed optimal quality of preparation in 76.9 % of patients in group 1 and in 84.6 % in group 2 (p = ns). Patient tolerability to both preparations was not different. A limited bowel preparation consisting of 1-L PEG and four tablets of bisacodyl in association with 90 mL of Iodine for faecal tagging administered on the same day as CTC examination is feasible and offers bowel cleansing comparable to ''iodine-only'' preparation.

    Full Text Available Cyclophosphamide is an immunosuppressive agent and an anticancer prodrug which requires bioactivation catalyzed primarily by cytochrome P450 enzymes in order to be transformed into its active alkylating compounds. Concomitant administration of drugs known to inhibit or induce this enzyme system is a clinical concern. Herein, we present the case of a chronically ill 21-year-old patient who received high-dose cyclophosphamide, equine antithymocyte globulin (eATG, and total body irradiation (TBI followed by an allogeneic hematopoietic stem cell transplant (HSCT for severe aplastic anemia. Throughout her hospitalization, she continued to receive quadruple anticonvulsant therapy including phenobarbital for her long-standing seizure history. The preparative regimen was tolerated well aside from a hypersensitivity reaction to eATG, and minimal cyclophosphamide-related toxicities. Safe and effective administration of high-dose cyclophosphamide was possible with multidisciplinary care consisting of physician, nursing, pharmacy, neurology consultation, as well as social work and case management.

    AIM: To compare(using the Ottawa Bowel Preparation Scale) the efficacy of split-dose vs morning administration of polyethylene glycol solution for colon cleansing in patients undergoing colonoscopy, and to assess the optimal preparation-to-colonoscopy interval.METHODS: Single-centre, prospective, randomized, investigator-blind stud in an academic tertiarycare centre. Two hundred patients requiring elective colonoscopy were assigned to receive one of the two preparation regimens(split vs morning) prior to colonoscopy. Main outcome measurements were bowel preparation quality and patient tolerability.RESULTS: Split-dose regimen resulted in better bowel preparation compared to morning regimen [Ottawascore mean 5.52(SD 1.23) vs 6.02(1.34); P = 0.017]. On subgroup analysis, for afternoon procedures, both the preparations were equally effective(P = 0.756). There was no difference in tolerability and compliance between the two regimens.CONCLUSION: Overall, previous evening- same morning split-dosing regimen results in better bowel cleansing for colonoscopy compared to morning preparation. For afternoon procedures, both schedules are equally effective; morning preparation may be more convenient to the patient.

    Sena-Graph syrup has recently been formulated by an Iranian pharmaceutical company for being used in bowel evacuation before radiography, colonoscopy and surgery. This study compares the efficacy, adverse effects and patient compliance of two bowel preparation regimens with castor oil and Sena-Graph syrup in of outpatients for Intravenous Urography (IVU). One hundred and fourteen consecutive outpatients were randomized to receive either the standard bowel preparation with 60 mL of castor oil or the test method with 60 mL of Sena-Graph syrup before IVU examination. Demographic data of patients and their prior bowel preparation experience were collected before the examination. Two radiologists, blinded to the method of bowel preparation, reviewed the radiographs and graded the bowel preparation. The compliance and acceptability of both regimens were assessed by using structured questionnaires filled by the patients. The Numbers, ages, weights and gender distribution of patients and their prior bowel preparation experience in the two groups did not differ significantly. The cleanliness scores for the castor oil and Sena-Graph group were 3.97 ± 0.971 and 4.87 ± 0.917, respectively. The results indicated that Sena-Graph syrup causes a better bowel cleansing compared castor oil. Adverse effects in Sena-Graph groups were significantly lower than the castor oil group. Acceptability of the regimen in patients who used Sena-Graph was higher than the other group. The Sena-Graph regimen is significantly more effective and better tolerated than of Castor oil regimen in bowel cleansing. The incidence and severity of the adverse effects from Castor oil was higher than Sena-Graph.

  7. Role of total body irradiation as based on the comparison of preparation regimens for allogeneic bone marrow transplantation for acute leukemia in first complete remission

    International Nuclear Information System (INIS)

    The role of total body irradiation (TBI) for allogeneic bone marrow transplantation (BMT) for acute leukemia in first complete remission was reevaluated in this study. From Japanese BMT Registry, data of 123 acute leukemia patients in first complete remission who underwent allogeneic bone marrow transplantation in 22 hospitals between 1988 and 1990 were available for the present comparative study of preparation regimens with or without total body irradiation. Two-year survivals were 77% and 51% in the TBI containing regimen group and in the non-TBI regimen group, respectively (p=0.0010). Corresponding two-year relapse rates were 16% and 37%, respectively (p=0.0197). Corresponding probabilities of developing interstitial pneumonitis were 21% and 24%, respectively (p=0.8127). The analysis of causes of death indicated that non-TBI regimen increased the incidence of septicemia and lethal organ failures, such as liver, heart, lung and other multiple sites. It was emphasized that an additional role of total body irradiation was to disperse the treatment-related toxicity in allogeneic bone marrow transplantation for acute leukemia. (orig.)

    We compared total body irradiation (TBI, 700 cGy)/cyclophosphamide (Cy, 3.6 g/m(2))/simustine (250 mg/m(2)) plus antithymocyte globulin (ATG) (TBI/Cy plus ATG) with cytarabine (8 g/m(2))/i.v. busulfan (Bu, 9.6 mg/kg)/Cy (3.6 g/m(2))/simustine (250 mg/m(2)) plus ATG (modified Bu/Cy plus ATG) as preparative therapy in T cell-replete haploidentical hematopoietic stem cell transplantation (haplo-HSCT) for acute leukemia. From August 2009 to August 2013, 38 consecutive patients using TBI/Cy plus ATG regimen for T cell-replete haplo-HSCT (TBI group) at our center were eligible, which contained 28 high-risk and 10 standard-risk patients. A nested case-control study was designed. Seventy-seven patients using modified Bu/Cy plus ATG regimen (Bu group) were randomly selected in a 1 to 3:1 ratio matching for age, disease and status, year of HSCT (±2 years), and length of follow-up. Only 1 graft failure occurred in the TBI group. The incidence and time of neutrophil and platelet engraftment were comparable between the 2 groups. Severe grades III/IV graft-versus-host disease was observed in 13.4% of Bu group and only 2.6% of TBI group (P = .083). More toxicity of the liver (37.7% versus 10.5%; P = .002) and more hemorrhagic cystitis occurred in the Bu group (49.3% versus 23.7%, P = .008). Diarrhea was more common in the TBI group (44.7% versus 22.1%; P = .031). No significant differences were found in the 2-year incidences of relapse (26.5% for TBI group versus 32.3% for Bu group, P = .742), 1-year transplant-related mortality (12.6% versus 16.2%, P = .862), 2-year overall survival (60.2% versus 57.0%, P = .937), and 2-year incidence of disease-free survival (57.9% versus 56.6%, P = .845) between the 2 groups. We conclude that the TBI/Cy plus ATG regimen seems to be feasible in T cell-replete haplo-HSCT, which promotes stable engraftment and a lower incidence of liver toxicity and hemorrhagic cystitis. However, longer follow-up is necessary to

    Full Text Available Abstract For patients who require replacement therapy for primary immunodeficiency, subcutaneous infusions of immunoglobulin G (IgG may be preferable to intravenous infusions for several reasons. However, at present, there is no preparation marketed for use by this route in North America. In this article, we describe the reasons patients have selected this route of therapy and the range of treatment regimens used. Approximately 20% of our patients have chosen the subcutaneous route, mainly because of adverse effects from intravenous (IV infusions or difficulties with venous access. Unit dose regimens using whole bottles of currently available 16% intramuscular preparations or sucrose-containing lyophilized preparations intended for IV use but reconstituted to 15% IgG for subcutaneous administration were individually tailored to each patient. In most cases, self-infusions or home infusions were administered once or twice a week, most commonly requiring two subcutaneous sites and 2 to 3 hours per infusion. On average, patients took 0.18 mL of IgG per kilogram of body weight per site per hour. There were no systemic adverse effects. In patients for whom comparative data were available, trough serum IgG levels were higher with subcutaneous therapy than with IV therapy.

The concept of an individually tailored medicine accounts for a broad variety of different insulin regimens applied. Despite clear recommendations for insulin management in children and adolescents with type 1...... diabetes there is little distinctiveness about concepts and the nomenclature is confusing. Even among experts similar terms are used for different strategies.

    We investigated a dose-reduced conditioning regimen consisting of treosulfan and fludarabine followed by allogeneic stem cell transplantation (SCT) in 26 patients with secondary AML or MDS. Twenty patients were transplanted from matched or mismatched unrelated donors and six from HLA-identical sibling donors. The median age of the patients was 60 years (range, 44-70). None of the patients was eligible for a standard myeloablative preparative regimen. No graft-failure was observed, and leukocyte and platelet engraftment were observed after a median of 16 and 17 days, respectively. Acute graft-versus-host disease (GvHD) grade II-IV was seen in 23% and severe grade III GvHD in 12% of the patients. No patients experienced grade IV acute GvHD. Chronic GvHD was noted in 36% of the patients, which was extensive disease in 18%. The 2-year cumulative incidence of relapse was 21%. The relapse rate was higher in patients beyond CR1 or with intermediate two or high risk MDS (P = 0.02). The treatment-related mortality at day 100 was 28%. The 2-year estimated overall and disease-free survival was 36-34%, respectively. No difference in survival was seen between unrelated and related SCT.

    Helicobacter pylori (H pylori)infection is the main cause of gastritis,gastroduodenal ulcer disease,and gastric cancer.After more than 20 years of experience in Hpylori treatment,in my opinion,the ideal regimen to treat this infection is still to be found.Currently,apart from having to know first-line eradication regimens well,we must also be prepared to face lyeatment failures.Therefore,in designing a treatment strategy we should not focus on the results of primary therapy alone,but also on the final (overall) eradication rate.The choice of a "rescue" treatment depends on which treatment is used initially.If a clarithromycinbased regimen was used initially,a subsequent metronidazole-based treatment (quadruple therapy)may be used afterwards,and then a levofloxacinbased combination would be a third "rescue" option.Alternatively,it has recently been suggested that levofloxacin-based rescue therapy constitutes an encouraging second-line strategy,representing an alternative to quadruple therapy in patients with previous PPI-clarithromycin-amoxicillin failure,with the advantage of efficacy,simplicity and safety.In this case,a quadruple regimen may be reserved as a third-line rescue option.Finally,rifabutin-based rescue therapy constitutes an encouraging empirical fourthline strategy after multiple previous eradication failures with key antibiotics such as amoxicillin,clarithromycin,metronidazole,tetracycline,and levofloxacin.Even after two consecutive failures,several studies have demonstrated that H pylor/eradication can finally be achieved in almost all patients if several rescue therapies are consecutively given.Therefore,the attitude in H pylori eradication therapy failure,even after two or more unsuccessful attempts,should be to fight and not to surrender.

    We aimed to examine whether doses of melphalan higher than 200 mg/m(2) improve response rates when used as conditioning before autologous transplant (ASCT) in multiple myeloma (MM) patients. Patients with MM, n=131, were randomized to 200 mg/m(2) (mel200) vs 280 mg/m(2) (mel280) using amifostine pretreatment. The primary end point was the proportion of patients achieving near complete response (⩾nCR). No treatment-related deaths occurred in this study. Responses following ASCT were for mel200 vs mel280, respectively, ⩾nCR 22 vs 39%, P=0.03, ⩾PR 57 vs 74%, P=0.04. The hazard of mortality was not statistically significantly different between groups (mel200 vs mel280; hazard ratio (HR)=1.15 (95% confidence interval (CI), 0.62-2.13, P=0.66)) nor was the rate of progression/mortality (HR=0.81 (0.52-1.27, P=0.36)). The estimated PFS at 1 and 3 years were 83 and 46%, respectively, for mel200 and 78 and 54%, respectively, for mel280. Amifostine and mel280 were well tolerated, with no grade 4 regimen-related toxicities and only one grade 3 mucositis (none with mel200) and three grade 3 gastrointestinal (GI) toxicities (two in mel200). Hospitalization rates were more frequent in the mel280 group (59 vs 43%, P=0.08). Mel280 resulted in a higher major response rate (CR+nCR) and should be evaluated in larger studies. PMID:26367217

    Tuberculosis is an airborne infectious disease treated with combination therapeutic regimens. Adherence to long-term antituberculosis therapy is crucial for maintaining adequate blood drug level. The emergence and spread of drug-resistant Mycobacterium tuberculosis strains are mainly favored by the inadequate medical management of the patients. The therapeutic approach for drug-resistant tuberculosis is cumbersome, because of the poor, expensive, less-effective, and toxic alternatives to the first-line drugs. New antituberculosis drugs (bedaquiline and delamanid) have been recently approved by the health authorities, but they cannot represent the definitive solution to the clinical management of drug-resistant tuberculosis forms, particularly in intermediate economy settings where the prevalence of drug resistance is high (China, India, and former Soviet Union countries). New research and development activities are urgently needed. Public health policies are required to preserve the new and old therapeutic options. PMID:25573773

    To establish the optimum barium-based reduced-laxative tagging regimen prior to CT colonography (CTC). Ninety-five subjects underwent reduced-laxative (13 g senna/18 g magnesium citrate) CTC prior to same-day colonoscopy and were randomised to one of four tagging regimens using 20 ml 40%w/v barium sulphate: regimen A: four doses, B: three doses, C: three doses plus 220 ml 2.1% barium sulphate, or D: three doses plus 15 ml diatriazoate megluamine. Patient experience was assessed immediately after CTC and 1 week later. Two radiologists graded residual stool (1: none/scattered to 4: >50% circumference) and tagging efficacy for stool (1: untagged to 5: 100% tagged) and fluid (1: untagged, 2: layered, 3: tagged), noting the HU of tagged fluid. Preparation was good (76-94% segments graded 1), although best for regimen D (P = 0.02). Across all regimens, stool tagging quality was high (mean 3.7-4.5) and not significantly different among regimens. The HU of layered tagged fluid was higher for regimens C/D than A/B (P = 0.002). Detection of cancer (n = 2), polyps {>=}6 mm (n = 21), and {<=}5 mm (n = 72) was 100, 81 and 32% respectively, with only four false positives {>=}6 mm. Reduced preparation was tolerated better than full endoscopic preparation by 61%. Reduced-laxative CTC with three doses of 20 ml 40% barium sulphate is as effective as more complex regimens, retaining adequate diagnostic accuracy. (orig.)

    Colonoscopy has been accepted as the standard method for evaluation of colon and rectum,its success rate depends on the quality of bowel preparation. Aims:To evaluate the cleanliness and tolerance of fractionated dose versus single dose polyethylene glycol electrolyte solution( PEG-ES) bowel preparation regimens for colonoscopy. Methods:A total of 427 consecutive asymptomatic individuals undergoing colorectal cancer screening were enrolled and randomly assigned into 2 groups. Subjects in group A drank 1. 5 L PEG-ES on the eve and 4 hours before colonoscopy, respectively;subjects in group B received a single dose of 3 L PEG-ES 5 hours before colonoscopy. Score and degree of Boston bowel preparation scale(BBPS)and PEG-ES related adverse effects of the two groups were assessed and compared. Results:There were no significant differences in gender,age and cecal insertion rate between group A and group B(P ﹥ 0. 05). Score of BBPS was significantly higher in group A than in group B(P ﹤0. 01). Both regimens met the requirement of conventional colonoscopy,however,the cleanliness of colon was graded as excellent in more subjects of group A( P ﹤ 0. 01),and less subjects of group A complained PEG-ES related nausea(P ﹤0. 05). Logistic regression analysis revealed that the PEG-ES drinking pattern was associated with cleanliness of colon and occurrence of nausea( P ﹤ 0. 05). Conclusions:Fractionated dose PEG-ES regimen provides a better colonic cleansing quality and tolerance for bowel preparation of colonoscopy,which is superior to that of single dose regimen.%背景:结肠镜检查是公认的结直肠检查的金标准,而良好的肠道准备是检查成功的前提条件。目的:评价聚乙二醇电解质溶液( PEG-ES)分次与单次口服作为结肠镜检查肠道准备方案的清洁效果和耐受性。方法:连续纳入427例进行结直肠癌筛查的无症状个体,随机分为A组和B组。A组于检查前夜和检查前4 h分别口服1

  3. Cleansing the colon in gallium-67 scintigraphy: a prospective comparison of regimens

    International Nuclear Information System (INIS)

    Colonic accumulation of gallium-67 frequently complicates the interpretation of gallium-67 scintigrams. Although various modes of cleansing the colon prior to scintigraphy have been suggested, there is controversy over their efficacy and none have been tested prospectively. Three hundred nine patients undergoing gallium-67 scintigraphy were randomly assigned to one of four cleansing regimens: (1) a high fiber diet (78 patients); (2) castor oil (76); (3) milk of magnesia and cascara (76); and (4) not preparation (79). Patient compliance rates for the four regimens were 17%, 32%, 36%, and 46%, respectively. After noncompliant patients were excluded, gallium-67 scintigrams were graded for colonic activity on a scale of 0-3 by three independent, experienced observers. Gallium-67 activity in the colon was significantly less after administration of castor oil than after no preparation (p . 0.047). A high fiber diet also resulted in a substantial reduction of colonic activity when compared with no preparation; the difference, however, was not statistically significant (p . 0.083). Regimen 3 did not produce significantly better results than regimen 4 (p . 0.42). A major impediment to the success of any cleansing regimen seems to be poor compliance of patients

  7. CT colonography: optimisation, diagnostic performance and patient acceptability of reduced-laxative regimens using barium-based faecal tagging

    International Nuclear Information System (INIS)

    To establish the optimum barium-based reduced-laxative tagging regimen prior to CT colonography (CTC). Ninety-five subjects underwent reduced-laxative (13 g senna/18 g magnesium citrate) CTC prior to same-day colonoscopy and were randomised to one of four tagging regimens using 20 ml 40%w/v barium sulphate: regimen A: four doses, B: three doses, C: three doses plus 220 ml 2.1% barium sulphate, or D: three doses plus 15 ml diatriazoate megluamine. Patient experience was assessed immediately after CTC and 1 week later. Two radiologists graded residual stool (1: none/scattered to 4: >50% circumference) and tagging efficacy for stool (1: untagged to 5: 100% tagged) and fluid (1: untagged, 2: layered, 3: tagged), noting the HU of tagged fluid. Preparation was good (76-94% segments graded 1), although best for regimen D (P = 0.02). Across all regimens, stool tagging quality was high (mean 3.7-4.5) and not significantly different among regimens. The HU of layered tagged fluid was higher for regimens C/D than A/B (P = 0.002). Detection of cancer (n = 2), polyps ≥6 mm (n = 21), and ≤5 mm (n = 72) was 100, 81 and 32% respectively, with only four false positives ≥6 mm. Reduced preparation was tolerated better than full endoscopic preparation by 61%. Reduced-laxative CTC with three doses of 20 ml 40% barium sulphate is as effective as more complex regimens, retaining adequate diagnostic accuracy. (orig.)

    Full Text Available Previous published evidences showed that taking HAART once-daily (OD is associated to better adherence when compared to BID or TID regimens. However, no further studies investigated whether, among OD regimens, adherence levels can be differently influenced. Aim of the study was to evaluate levels of self-reported adherence in HIV+ people according to type of HAART dosing (STR, OD with more than one pill or BID. To limit reporting biases, the study was performed in five different non-clinic settings covering North and Central Italy. A total of 230 patients on stable HAART were asked to complete a semi-structured, anonymous questionnaire reporting their attitude toward HAART, their adherence and the acceptability of their regimen. Self-perception of adherence was also investigated with a single item for comparison with real adherence behavior. Most of the subjects were males (66% with a mean age of 46 years, with higher education level (72% and a long history of HIV infection (mean 13.6 years. 17% of patients were on a first-line regimen. 21% reported to miss at least one dose during the past week (STR: 6%; OD >1 pill 23% and BID 21%; p<0.05. People taking STR and BID tend to report less discontinuations (all the drug of the day for at least 3 times in a month compared to OD>1 pill (6 and 4% vs 11%. People taking therapies other than HAART reported similar adherence levels of people taking only HAART, even when stratified for dosing groups. Even people judging their adherence as ‘optimal’ or ‘very good’, 10 and 17% respectively, reported having missed a dose during the last week. At stepwise regression model, optimal adherence was correlated to being male (OR: 2.38; 95% CI: 1.19–4.74, younger (OR: 3.04; 95% CI: 1.01–9.13 and with a shorter HIV infection (OR: 3.58; 95% CI: 1.04–12.38. People taking simpler once-daily STR tend to report better adherence than people taking OD>1 pill or BID. Perception of optimal adherence is largely

    Full Text Available During video capsule endoscopy (VCE, several factors, such as air bubbles, food material in the small bowel, and delayed gastric and small bowel transit time, influence diagnostic yield, small bowel visualization quality, and cecal completion rate. Therefore, bowel preparation before VCE is as essential as bowel preparation before colonoscopy. To date, there have been many comparative studies, consensus, and guidelines regarding different kinds of bowel cleansing agents in bowel preparation for small bowel VCE. Presently, polyethylene glycol- (PEG- based regimens are given primary recommendation. Sodium picosulphate-based regimens are secondarily recommended, as their cleansing efficacy is less than that of PEG-based regimens. Sodium phosphate as well as complementary simethicone and prokinetics use are considered. In this paper, we reviewed previous studies regarding bowel preparation for small bowel VCE and suggested optimal bowel preparation of VCE.

    This paper examines the use of evolutionary algorithms in the development of antibiotic regimens given to production animals. A model is constructed that combines the lifespan of the animal and the bacteria living in the animal's gastro-intestinal tract from the early finishing stage until the animal reaches market weight. This model is used as the fitness evaluation for a set of graph based evolutionary algorithms to assess the impact of diversity control on the evolving antibiotic regimens. The graph based evolutionary algorithms have two objectives: to find an antibiotic treatment regimen that maintains the weight gain and health benefits of antibiotic use and to reduce the risk of spreading antibiotic resistant bacteria. This study examines different regimens of tylosin phosphate use on bacteria populations divided into Gram positive and Gram negative types, with a focus on Campylobacter spp. Treatment regimens were found that provided decreased antibiotic resistance relative to conventional methods while providing nearly the same benefits as conventional antibiotic regimes. By using a graph to control the information flow in the evolutionary algorithm, a variety of solutions along the Pareto front can be found automatically for this and other multi-objective problems.

    The level of pain following the extraction of impacted third molars was evaluated in 75 patients. Participants were administered acetaminophen 1,000 mg or a placebo before surgery. After surgery, acetaminophen 650 mg was administered either at fixed intervals or as needed to relieve pain. When acetaminophen was administered before surgery, the onset of peak pain was delayed and patient discomfort was decreased 3, 4, and 5 hours after surgery. Patients following the fixed interval regimen after surgery experienced more pain overall and requested the backup narcotic analgesic more frequently. Of the regimens tested, patients preferred the regimen of acetaminophen 1,000 mg administered before surgery with acetaminophen administered as needed for pain after surgery. PMID:3465787

    Full Text Available The relationship between characteristics of HIV antiretroviral regimens and treatment adherence was studied in adolescent and adult patients who underwent antiretroviral therapy from January 1998 to September 2000, at the Service for Specialized Assistance in Pelotas. The patients were interviewed on two occasions, and the use of antiretrovirals during the previous 48 hours was investigated by a self-report. Adherence was defined as use of 95% or more of the prescribed medication. Social-demographic variables were collected through direct questionnaires. The antiretroviral regimen and clinical data were copied from the patients' records. Associations between the independent variables and adherence were analyzed by means of logistic regression. The multivariate analysis included characteristics of the antiretroviral regimens, social-demographic variables, as well as perception of negative effects, negative physiological states, and adverse effects of the treatment. Among the 224 selected patients, 194 participated in our study. Their ages varied from 17 to 67 years; most patients were men, with few years of schooling and a low family income. Only 49% adhered to the treatment. Adherence to treatment regimens was reduced when more daily doses were indicated: three to four doses (odds ratio of adherence to treatment (OR=0.47, 95% confidence interval (CI 0.22-1.01 and five to six (OR=0.24, 95% CI 0.09-0.62; two or more doses taken in a fasting state (OR=0.59, 95% CI 0.11-0.68, and for patients who reported adverse effects to the treatment (OR=0.39, 95% CI 0.19-0.77. Most of the regimens with more than two daily doses of medication included at least one dose apart from mealtimes. The results suggest that, if possible, regimens with a reduced number of doses should be chosen, with no compulsory fasting, and with few adverse effects. Strategies to minimize these effects should be discussed with the patients.

    Abstract Patients’ experience during treatment may affect treatment adherence. Our aim was to assess the impact of patient-reported outcomes (PROs) on adherence to different anti-hepatitis C virus (HCV) regimens. Clinical, demographic, and PRO data (short form-36 [SF-36], chronic liver disease questionnaire-hepatitis C version [CLDQ-HCV], functional assessment of chronic illness therapy-fatigue [FACIT-F], work productivity and activity impairment: specific health problem [WPAI:SHP]) from 13 multinational clinical trials of anti-HCV treatment were available. Treatment adherence was defined as >80% of prescribed doses taken. Included were 4825 HCV patients. Regimens were grouped into: interferon- and ribavirin (RBV)-containing (±sofosbuvir [SOF]), interferon-free RBV-containing (RBV + SOF ± ledipasvir [LDV]), and interferon-free RBV-free (LDV/SOF). The adherence to these regimens were 77.6%, 84.3%, and 96.2%, respectively (P  0.05) for the small number of patients who were nonadherent to LDV/SOF. In multivariate analysis, being treatment-naive, longer treatment duration, and receiving an interferon- or RBV-containing regimen were associated with a lower likelihood of adherence (all P < 0.003). Better baseline and on-treatment PRO scores were associated with a higher likelihood of adherence to interferon and RBV. The use of interferon and/or RBV, longer duration of treatment, and lower baseline and on-treatment PRO scores were linked to a decreased likelihood of being adherent to interferon + RBV-containing or interferon-free RBV-containing antiviral regimens. Interferon- and RBV-free regimens were associated with excellent adherence. PMID:27428205

Reducing the frequency of RBV intake from twice to once a day will improve compliance and opens up the opportunity to combine RBV with new and more specific direct-acting agents in one pill. Therefore, the purpose of this study was to evaluate the pharmacokinetic profile of RBV in a once-daily to twice-daily regimen. The secondary aim was to determine tolerability as well as the severity and differences in side effects of both treatment regimens. Methods: In this randomized open-label crossover study, twelve patients with chronic type 1 hepatitis C infection and weighing more than 75 kg were treated with 180 µg of PEG-IFN weekly and 1,200 mg RBV daily for 24 weeks. The patients received RBV dosed as 1,200 mg once-daily for 12 weeks followed by RBV dosed as 600 mg twice-daily for 12 weeks, or vice versa. In addition to the pharmacokinetic profile, the hematological profile and side effects were recorded. The RBV concentrations in plasma were determined using liquid chromatography-tandem mass spectrometry. Results: Eight of twelve patients completed the study. Neither the time taken for RBV to reach peak plasma concentration nor the AUC0-last (adjusted for difference in dose was significantly different between the two groups (P>0.05. Furthermore, the once-daily regimen did not give more side effects than the twice-daily regimen (P>0

    Calcium and vitamin D supplementation has been shown to reduce secondary hyperparathyroidism and play a role in the management of senile osteoporosis. In order to define the optimal regimen of calcium and vitamin D supplementation to produce the maximal inhibition of parathyroid hormone secretion, we have compared the administration of a similar amount of Ca and vitamin D, either as a single morning dose or split in two doses, taken 6 hours apart. Twelve healthy volunteers were assigned to three investigational procedures, at weekly intervals. After a blank control procedure, when they were not exposed to any drug intake, they received two calcium-vitamin D supplement regimens including either two doses of Orocal D3 (500 mg Ca and 400 IU vitamin D) 6 hours apart or one water-soluble effervescent powder pack of Cacit D3 in a single morning dose (1000 mg Ca and 880 IU vitamin D). During the three procedures (control and the two calcium-vitamin D supplementations), venous blood was drawn every 60 minutes for up to 9 hours, for serum Ca and serum PTH measurements. The order of administration of the two Ca and vitamin D supplementation sequences was allocated by randomization. No significant changes in serum Ca were observed during the study. During the 6 hours following Ca and vitamin D supplementation, a statistically significant decrease in serum PTH was observed with both regimens, compared with baseline and with the control procedure. Over this period of time, no differences were observed between the two treatment regimens. However, between the sixth and the ninth hour, serum PTH levels were still significantly decreased compared with baseline with split dose Orocal D3 administration, while they returned to baseline value with the Cacit D3 preparation. During this period, the percentage decrease in serum PTH compared with baseline was significantly more pronounced with Orocal D3 than with Cacit D3 (P = 0.0021). We therefore conclude that the administration of two

    The advent of combination antiretroviral drug regimens has transformed HIV infection from a fatal illness into a manageable chronic condition. All patients with HIV infection should be considered for antiretroviral therapy, regardless of CD4 count or HIV viral load, for individual benefit and to prevent HIV transmission. Antiretroviral drugs affect HIV in several ways: entry inhibitors block HIV entry into CD4 T cells; nucleotide and nucleoside reverse transcriptase inhibitors prevent reverse transcription from RNA to DNA via chain-terminating proteins; nonnucleoside reverse transcriptase inhibitors prevent reverse transcription through enzymatic inhibition; integrase strand transfer inhibitors block integration of viral DNA into cellular DNA; protease inhibitors block maturation and production of the virus. Current guidelines recommend six combination regimens for initial therapy. Five are based on tenofovir and emtricitabine; the other uses abacavir and lamivudine. Five include integrase strand transfer inhibitors. HIV specialists should assist with treating patients with complicated HIV infection, including patients with treatment-resistant HIV infection, coinfection with hepatitis B or C virus, pregnancy, childhood infections, severe opportunistic infections, complex drug interactions, significant drug toxicity, or comorbidities. Family physicians can treat most patients with HIV infection effectively by choosing appropriate treatment regimens, monitoring patients closely, and retaining patients in care. PMID:27092564

    Full Text Available A taxa de mortalidade entre os pacientes em hemodiálise (HD é extremamente elevada. A expectativa de vida restante de um paciente ao iniciar HD é apenas cerca de um quarto daquela da população geral com a mesma idade. O esquema convencional de HD, com três sessões semanais de cerca de quatro horas, foi estabelecido de maneira empírica há cerca de quatro décadas e merece ser reavaliado criticamente. Desde a falha do Estudo HEMO em demonstrar benefícios clínicos com o aumento do Kt/V de ureia nos pacientes em esquema convencional de HD, tem havido um crescente interesse pelos esquemas alternativos de HD com o intuito de prover um tratamento associado com uma melhor sobrevida. Dentre os esquemas mais promissores, destacam-se a HD diária de curta duração e a HD noturna prolongada. As limitações econômicas que inibem a aplicação dos conhecimentos emergentes nesta área devem ser vencidas.The mortality rate among patients on hemodialysis (HD is extremely high. Remaining life expectancy for a patient initiating HD is only approximately one quarter of that of the general population at the same age bracket. The conventional HD regimen based on four-hour sessions three times a week was empirically established nearly four decades ago and needs to be revisited. Since the failure of the HEMO Study to demonstrate the clinical benefits of higher urea Kt/V for patients on conventional HD, an increasing interest for alternative HD regimens has emerged aiming at providing a treatment for improving survival rates. Short daily HD and long nocturnal HD stand out as the most promising alternative regimens. Economical obstacles which could hinder the clinical application of emerging knowledge in the field should be overcome.

    A pharmacokinetic slide rule to facilitate the computations based on relatively simple pharmacokinetic principles involved in the development of individualized drug dosage regimens is described. The calculations are based on the assumption that the body can be conceived as a one-compartment open model with drug elimination proceeding by apparent first-order kinetics. Examples are presented (1) to illustrate the clinical application of a slide rule to compute the time-course of drug in the body, (2) to calculate steady-state maximum and minimum levels, and accumulation during multiple dosage and (3) to estimate appropriate maintenance doses and intravenous infusion rates.

    @@ It has been of a long long history to treat tumor with traditional Chinese medicine (TCM), in the last 50years, Chinese medicine (CM) has been accepted by more and more medical professionals and patients, and used as one of the principal methods for treating tumor in China. But, tumor is a kind of disease with rapid progress and complicated causes, and applying CM in treating tumor has to meet some requirement, as improper application could induce contrary effects. To reduce the chance of blind and improper application of CM in the treatment of tumor, it is vital to work out a standardized therapeutic regimen that can be used as the guideline.

    While diaphyseal fractures of the forearm are a common orthopedic injury, Galeazzi fractures are difficult to treat. The current knowledge on pathobiomechanics and modified therapeutic decisions implicate the need to devise an updated classification and treatment regimen of Galeazzi fractures. We challenge the concept that isolated fractures of the radius should be considered as a Galeazzi fractures as long as stability of the distal radioulnar joint is not proven. Contrary to others we demonstrate that the fracture location alone is not sufficient to determine the stability of the distal radioulnar joint.

  1. Fractionated External Beam Radiotherapy as a Suitable Preparative Regimen for Hepatocyte Transplantation After Partial Hepatectomy

    International Nuclear Information System (INIS)

    Purpose: Hepatocyte transplantation is strongly considered to be a promising option to correct chronic liver failure through repopulation of the diseased organ. We already reported on extensive liver repopulation by hepatocytes transplanted into rats preconditioned with 25-Gy single dose selective external beam irradiation (IR). Herein, we tested lower radiation doses and fractionated protocols, which would be applicable in clinical use. Methods and Material: Livers of dipeptidylpeptidase IV (DPPIV)-deficient rats were preconditioned with partial liver external beam single dose IR at 25 Gy, 8 Gy, or 5 Gy, or fractionated IR at 5 x 5 Gy or 5 x 2 Gy. Four days after completion of IR, a partial hepatectomy (PH) was performed to resect the untreated liver section. Subsequently, 12 million wild-type (DPPIV+) hepatocytes were transplanted via the spleen into the recipient livers. The degree of donor cell integration and liver repopulation was studied 16 weeks after transplantation by means of immunofluorescence and DPPIV-luminescence assay. Results: Donor hepatocyte integration and liver repopulation were more effective in the irradiated livers following pretreatment with the IR doses 1 x 25 Gy and 5 x 5 Gy (formation of large DPPIV-positive cell clusters) than single-dose irradiation at 8 Gy or 5 Gy (DPPIV-positive clusters noticeably smaller and less frequent). Quantitative analysis of extracted DPPIV revealed signals exceeding the control level in all transplanted animals treated with IR and PH. Compared with the standard treatment of 1 x 25 Gy, fractionation with 5 x 5 Gy was equally efficacious, the Mann-Whitney U test disclosing no statistically significant difference (p = 0.146). The lower doses of 1 x 5 Gy, 1 x 8 Gy, and 5 x 2 Gy were significantly less effective with p < 0.05. Conclusion: This study suggests that fractionated radiotherapy in combination with PH is a conceivable pretreatment approach to prime the host liver for hepatocyte transplantation, thus bringing the experimental model a step closer to clinical application.

    2013-06-01

    The current treatment regimen against drug susceptible tuberculosis (DS-TB) was defined by the 1980s. Since then the emergence of the global HIV pandemic and the escalation of drug resistant (DR-) forms of TB have presented new challenges for therapeutic research. Priority goals include shortening DS-TB treatment, improving DR-TB treatment and making combined TB-HIV therapy easier. To help achieve these goals, a range of new drugs and treatment strategies are currently being evaluated. Phase IIb and III clinical trials are ongoing to assess combinations involving the high-dose rifamycins, the 8-methoxyquinolones, a diarylquinoline (bedaquiline) and the nitroimidazoles. Other compounds (e.g. novel oxazolidinones and ethylenediamines) are at earlier stages of clinical development. Overall, there are grounds for optimism that recent advances will contribute towards achievement of new treatment regimens in the foreseeable future. However, long-term investment, political commitment and scientific endeavour are crucial to ensure that progress is sustained and the benefits of recent advances reach those in the greatest need.

    Full Text Available Over 480 000 cases of multidrug-resistant (MDR tuberculosis (TB occur every year globally, 9% of them being affected by extensively drug-resistant (XDR strains of Mycobacterium tuberculosis. The treatment of MDR/XDR-TB is unfortunately long, toxic and expensive, and the success rate largely unsatisfactory (<20% among cases with resistance patterns beyond XDR. The aim of this review is to summarise the available evidence-based updated international recommendations to manage MDR/XDR-TB, and to update the reader on the role of newly developed drugs (delamanid, bedaquiline and pretomanid as well as repurposed drugs (linezolid and meropenem clavulanate, among others used to treat these conditions within new regimens. A nonsystematic review based on historical trials results as well as on recent literature and World Health Organization (WHO guidelines has been performed, with special focus on the approach to managing MDR/XDR-TB. The new, innovative global public health interventions, recently approved by WHO and known as the “End TB Strategy”, support the vision of a TB-free world with zero death, disease and suffering due to TB. Adequate, universally accessed treatment is a pre-requisite to reach TB elimination. New shorter, cheap, safe and effective anti-TB regimens are necessary to boost TB elimination.

    Without any doubt the regimen used to mature multiple capable oocytes for IVF impacts IVF outcomes. Studies have indicated that the inclusion of LH activity, adjuvant agents such as growth hormone (GH), and regimens providing for simultaneous action of both LH and FSH during final oocyte maturation may have beneficial effects on IVF outcomes. Because of the difficulty in improving IVF outcomes in poor responders, the studies on GH are of particular interest. As pointed out in this review, the apparent beneficial effects of GH on oocyte competence may also apply to older women or to normal responders with reduced embryo quality. A much more difficult question is whether and how much ovarian stimulation impacts on oocyte competence. Paradoxically it seems that there are not demonstrated differences between the stimulated and the natural unstimulated cycle, whereas studies in laboratory animals and IVF patients have shown deleterious effects of higher compared with lower doses of gonadotropins. Recent studies suggest that the use of high doses of gonadotropins as an independent factor correlates negatively with the probability of live birth, whereas a high ovarian response per se is associated with better cumulative pregnancy rates, owing to the availability of more euploid and good-quality embryos. Although adjunctive use of androgens has not been discussed here, it is briefly covered in the first review of this series. PMID:26826273

    2016-04-01

    There is an extensive literature regarding nonadherence with both therapeutic regimens and medication. This literature includes reviews of empirical research regarding the factors associated with nonadherence. Health care system, provider, and patient factors as well as the nature of the illness and therapeutic regimen all effect adherence rates. Different behavioral models for adherence counseling such as the Health Belief Model, the Theory of Reasoned Action, the Medication Interest Model, and Motivational Interviewing have also been reported in the research literature. This article will discuss the development of a brief model for patient counseling with specific techniques illustrated for pharmacists based on empirical findings that have demonstrated effectiveness in the adherence research literature. In addition, the article will address the measurement of the economic impact of medication nonadherence and propose a framework for assessing the cost-effectiveness of pharmacist counseling to increase adherence. The problem of nonadherence has significant effects upon health care expenditures through increase in physician's visits, emergency department incidents, rehospitalizations, and nursing home readmissions. Thus, the overall goal is to assist the pharmacist in developing a brief adherence counseling program in community pharmacy and evaluating the economic feasibility of the intervention demonstrating the value-added proposition of pharmacist intervention.

    Full Text Available Objectives. To compare the effectiveness of postcesarean thromboprophylaxis with two different regimens of bemiparin. Material and Methods. The study included 646 women with cesarean delivery in our hospital within a 1-year period, randomly assigned to one of two groups for prophylaxis with 3500 IU bemiparin once daily for 5 days or 3500 IU bemiparin once daily for 10 days. Results. There was one case of pulmonary embolism (first day following cesarean. An additional risk factor was present in 98.52% of the women, most frequently emergency cesarean, anemia, or obesity. The only risk factors for thromboembolic disease significantly related to pulmonary thromboembolism were placental abruption and prematurity. There were no differences in thromboembolic events among the two thromboprophylaxis regimens. Conclusions. Cesarean-related thromboembolic events were reduced in our study population due to the thromboprophylactic measures taken. Thromboprophylaxis with 3500 IU bemiparin once daily for 5 days following cesarean was sufficient to avoid thromboembolic events.

    Full Text Available Background: Chemotherapy Induced Nausea and Vomiting (CINV is a major problem for all cancer patients. 5-hydroxytryptamine 3 (5-HT3-receptor antagonists or serotonin antagonists used along with dexamethasone is the most widely used antiemetic regimen in chemotherapy. But the best drug of the different serotonin antagonists, which is both efficacious and economic, remains a matter of debate. Aims & Objectives: To compare the relative efficacies and safeties of ondansetron, granisetron and palonosetron, when used along with equal dose of dexamethasone, in moderately to highly emetogenic chemotherapy by a double blind, randomized controlled trial in order to obtain the most potent and cost effective drug. Methods: 1213 adult patients, 487 on highly and 726 on moderately emetogenic chemotherapy, admitted in various departments of a teaching hospital in India from November 05, 2007 to September 30, 2009 were included in the study. Patients were randomly assigned to receive ondansetron 8 mg or granisetron 3mg or palonosetron 0.75 mg (single dose, 30 min before receiving chemotherapy, along with 16 mg of intravenous dexamethasone on Day 1 and 4mg on Day 2 and 3. The observation period started with the initiation of chemotherapy (0 h and continued for 24 h after completion of the chemotherapy for acute emesis and up to Day 5 for delayed nausea and vomiting. Results: For highly emetogenic regimens, 52 of 64 patients (81.2% had complete response during the acute phase in palonosetron group compared with 181 of 237 patients (76.4% in the ondansetron group and 130 of 186 patients (69.9% in granisetron group. During the delayed phase, 41 patients (64% had complete response in the palonosetron group compared with 133 patients (56.1% in the ondansetron group and 114 patients (61.2% in granisetron group. For moderately emetogenic regimens, 86 of 93 patients (92.5% had complete response during the acute phase in palonosetron group compared with 291 of 379

    2006-01-01

    Rifaximin is a non-absorbed semisynthetic rifamycin derivative with a broad spectrum of antibacterial activity including Gram-positive and Gram-negative bacteria, both aerobes and anaerobes. Although originally developed for the treatment of infectious diarrhea, the appreciation of the pathogenic role of gut bacteria in several organic and functional gastrointestinal diseases has increasingly broadened its clinical use. Being the antibiotic active against Helicobacter pylori, even towards clarithromycin-resistant strain, and being the primary resistance very rare, several investigations explored its potential use for eradication of the microorganism. Rifaximin alone proved to be effective, but even the highest dose (1,200 mg daily) gave a cure rate of only 30%. Dual and triple therapies were also studied, with the better results obtained with rifaximin-clarithromycin and rifaximin-clarithromycin-esomeprazole combinations. However, the eradication rates (60-70%) obtained with these regimens were still below the standard set by the Maastricht Consensus guidelines. Although rifaximin-based eradication therapies are promising, new antimicrobial combinations (with and without proton pump inhibitors) need to be explored in well-designed clinical trials including a large cohort of H. pylori-infected patients. The remarkable safety of rifaximin will allow high-dose regimens of longer duration (e.g. 10 or 14 days) to be tested with confidence in the hope of achieving better eradication rates. A drawback of rifaximin could be its inability to reach sufficiently high concentrations in the gastric mucus layer under and within which H. pylori is commonly located and this would likely affect eradication rate. Taking these considerations into account, bioadhesive rifaximin formulations able to better and persistently cover gastric mucosa, or combination with mucolytic agents, such as pronase or acetylcysteine, need to be evaluated in order to better define the place of this

    Full Text Available A comparative study of cutaneous toxicities of two different commonly used combination chemotherapeutic regimens was conducted on 16 patients of non-Hodgkin′s lymphoma. The common drugs in the two regimens were cyclophosphamide, vincristine and prednisone. One of the regimens which was administered to 10 patients, included doxorubicin as an additional drug. This combination is preferred in high grade malignancy. However, the addition of doxorubicin resulted in enhanced severity and multiplicity of cutaneous manifestations. If it is possible to choose between two or more regimens for a given malignancy, the risk-benefit ratio can be weighed to choose the appropriate and least toxic drugs.

    Full Text Available RATIONALE: A better understanding of the composition of optimal treatment regimens for multidrug-resistant tuberculosis (MDR-TB is essential for expanding universal access to effective treatment and for developing new therapies for MDR-TB. Analysis of observational data may inform the definition of an optimized regimen. OBJECTIVES: This study assessed the impact of an aggressive regimen-one containing at least five likely effective drugs, including a fluoroquinolone and injectable-on treatment outcomes in a large MDR-TB patient cohort. METHODS: This was a retrospective cohort study of patients treated in a national outpatient program in Peru between 1999 and 2002. We examined the association between receiving an aggressive regimen and the rate of death. MEASUREMENTS AND MAIN RESULTS: In total, 669 patients were treated with individualized regimens for laboratory-confirmed MDR-TB. Isolates were resistant to a mean of 5.4 (SD 1.7 drugs. Cure or completion was achieved in 66.1% (442 of patients; death occurred in 20.8% (139. Patients who received an aggressive regimen were less likely to die (crude hazard ratio [HR]: 0.62; 95% CI: 0.44,0.89, compared to those who did not receive such a regimen. This association held in analyses adjusted for comorbidities and indicators of severity (adjusted HR: 0.63; 95% CI: 0.43,0.93. CONCLUSIONS: The aggressive regimen is a robust predictor of MDR-TB treatment outcome. TB policy makers and program directors should consider this standard as they design and implement regimens for patients with drug-resistant disease. Furthermore, the aggressive regimen should be considered the standard background regimen when designing randomized trials of treatment for drug-resistant TB.

    The aim of this study was to investigate the dietary regimens reported by athletes competing at a major international competition and report whether these were based on nutrient composition, religious beliefs, cultural eating style, food intolerance or avoidance of certain ingredients. A questionnaire was randomly distributed to 351 athletes in the main dining hall of the athletes' village over the three main meal periods during the Delhi 2010 Commonwealth Games (23rd Sept-14th Oct, 2010). The majority (n = 218, 62%) of athletes reported following one or more dietary regimens, with 50% (n = 174) following a diet based on the nutrient composition of the food. Significantly more athletes from weight category and aesthetic sports (28%, p = .005) and from power/sprint sports (41%, p = .004) followed low fat and high protein regimens respectively. Other specialized dietary regimens were followed by 33% of participants, with avoidance of red meat (13%), vegetarian (7%), Halal (6%), and low lactose regimens (5%) reported most frequently. Significantly more athletes from non-Western regions followed a vegetarian diet (p eating was the most commonly reported cultural regimen (72% of total with 23% from non-Western regions). Those following a Western diet were significantly more likely to report following a regimen based on nutrient composition (p = .02). As a high proportion of athletes from differing countries and sports follow specialized dietary regimens, caterers and organizers should ensure that adequate nutrition support and food items are available at similar events.

    This study was purposed to compare the clinical efficacy and adverse reactions of low-dose decitabine combined with CAG regimen (aclarubicin, Ara-C, and G-CSF) and CAG regimen alone in intermediate to high-risk myelodysplastic syndromes (MDS), and evaluate the validity and efficacy of the former regimen as new treatment method of intermediate to high-risk myelodysplastic syndromes. A total of 12 patients with intermediate (IR) to high-risk (HR) MDS treated by low-dose decitabine combined with CAG regimen and 10 patients with IR to HR MDS treated by CAG regimen alone were evaluated after treatment of 1 cycle and at least after 2 cycles. The complete remission (CR) after 1 cycle, overall remission rate (ORR), progression free survival (PFS) and overall survival (OS) between them were analyzed. The results showed that 9 patients treated by low-dose decitabine combined with CAG regimen achieved complete remission after 1 cycle, 2 patients achieved partial remission, 1 patient did not show reaction. The complete remission rate was 75.0% and overall response rate was 91.7%. The median time of disease free survival was 9 months (0-27 months). The median overall survival time was 16 months (3-28 months). 4 patients suffered from pulmonary infection after treatment and then were all cured after treatment with anti-infective therapy. The 5 patients treated by CAG regimen alone achieved complete remission,3 patients achieved partial remission, 2 patients showed non-reaction. The complete remission rate was 50.0% and overall response rate was 80.0%. The median time of disease free survival was 6 months(0-18 months). The median overall survival time was 13 months(3-31 months), 4 patients suffered from pulmonary infection, 1 patient suffered from enteric infection and 1 patient suffered from Escherichia coli septicemia after treatment, all of them becomed better after active treatment.

    Full Text Available Objective To assess the influence of final irrigation protocols with chlorhexidine in the coronal leakage of Enterococcus faecalis in filled root canals. Material and Methods Seventy single-root canals from extracted teeth were prepared using ProTaper instruments. The irrigation protocol accomplished an alternating irrigation with 5 mL of 2.5% sodium hypochlorite (NaOCI and 17% EDTA between each file. The teeth were randomly divided into four experimental groups (n=15 according to the final irrigation regimen: group 1, without final irrigation; group 2, irrigation with 10 mL 2.0% chlorhexidine (CHX; group 3, with a final application of EC40™; and group 4, irrigation with the combination (1:1 of 0.2% CHX + 0.1% cetrimide (CTR. All the teeth were mounted in a two-chamber apparatus and the coronal access was exposed to E. faecalis. The presence of turbidity in the BHI broth over a period of 180 days was observed. The Friedman test was used for statistical analysis. Results EC40™ varnish showed the least leakage at 180 days, and was statistically similar to 2% CHX. No significant differences were observed between the group without final irrigation and the 2% CHX group or 0.2% CHX + 0.1% CTR. Conclusions In this ex vivo study, EC40™ showed the longest delayed coronal leakage of E. faecalis, although without significant differences from 2% CHX.

    One hundred forty-three Angus x Simmental crossbred steers (initial BW = 155.1 +/- 4.5 kg) were used in a 2-yr study (yr 1, n = 67; yr 2, n = 76) to determine the effects of weaning age, implant regimen, and the weaning age x implant regimen interaction on steer growth and performance, organ mass, carcass characteristics, and cooked beef palatability. Steers were early-weaned at an average age of 108 d (EW) or normally weaned at an average age of 202 d (NW) and allotted by weight to an aggressive or nonaggressive implant regimen. On their respective weaning dates, EW and NW steers were penned individually and fed a grain-based diet until they were slaughtered at a final BW of 546 kg. A subsample of steers (n = 2 per treatment) were slaughtered at 254 kg. At 254 kg, EW steers implanted with the aggressive implant regimen had 64% greater backfat depth than those implanted with the nonaggressive implant regimen; conversely, NW steers implanted with the aggressive implant regimen had 52% lower backfat depth than those implanted with the nonaggressive implant regimen (weaning status x implant regimen interaction; P 0.37) or feed efficiency (P > 0.15). Weaning status did not affect carcass characteristics (P > 0.14), final empty body composition (P > 0.25), or final longissimus muscle composition (P > 0.18); however, steaks from EW steers had higher (P 0.86) compared to the nonaggressive implant regimen. Placing early-weaned steers on an aggressive implant regimen is a viable management option. PMID:11374527

    2015-01-01

    Objective: To compare efficacy and safety of primaquine regimens currently used to prevent relapses by P. vivax. Methods: A systematic review was carried out to identify clinical trials evaluating efficacy and safety to prevent malaria recurrences by P. vivax of primaquine regimen 0.5 mg/kg/ day for 7 or 14 days compared to standard regimen of 0.25 mg/kg/day for 14 days. Efficacy of primaquine according to cumulative incidence of recurrences after 28 days was determined. The overall relative risk with fixed-effects meta-analysis was estimated. Results: For the regimen 0.5 mg/kg/day/7 days were identified 7 studies, which showed an incidence of recurrence between 0% and 20% with follow-up 60-210 days; only 4 studies comparing with the standard regimen 0.25 mg/kg/day/14 days and no difference in recurrences between both regimens (RR= 0.977, 95% CI= 0.670 to 1.423) were found. 3 clinical trials using regimen 0.5 mg/kg/day/14 days with an incidence of recurrences between 1.8% and 18.0% during 330-365 days were identified; only one study comparing with the standard regimen (RR= 0.846, 95% CI= 0.484 to 1.477). High risk of bias and differences in handling of included studies were found. Conclusion: Available evidence is insufficient to determine whether currently PQ regimens used as alternative rather than standard treatment have better efficacy and safety in preventing relapse of P. vivax. Clinical trials are required to guide changes in treatment regimen of malaria vivax. PMID:26848199

    High-dose chemotherapy (HDC) applied together with autologous stem cell transplantation (ASCT) is a commonly used treatment modality in patients with malignant lymphoma. At present, there is a limited number of studies which compare toxicity and efficacy of various high-dose regimens applied in the treatment of malignant lymphoma. For this reason, the aim of this study was to investigate the efficacy and toxicity of BuCyE (busulfan, cyclophosphamide and etoposide) and BEAM (carmustine, etoposide, cytarabine and melphalan) preparative regimens in the patients with malignant lymphoma scheduled for autologous stem cell transplantation. Between November, 2010 and April, 2015, 42 patients with relapsed or refractory malignant lymphoma who underwent autologous stem cell transplantation following BEAM (n=11) and BuCyE (n=31) preparative regimens were analyzed at Bone Marrow Transplantation Unit of TurgutOzal Medicine Center in Turkey. The groups were compared in terms of patient characteristics, hematopoietic engraftment time, toxicity profiles and survival. No significant differences were detected between the groups with regard to age, gender distribution, international prognostic index, ASCT indications, disease status at the time of ASCT and type of lymphoma (P>0.05). Median number of infused CD34+ cells/kg, neutrophil and platelet engraftment statuses of BuCyE and BEAM groups were found to be similar (P>0.05). More patients in BuCyE group developed mucositis and nausea, but this difference was not statistically significant (P>0.05). A similar statistically insignificant difference was seen in that infectious complications occurred more commonly in BEAM group (P>0.05). Overall survival and event-free survival rates were not significantly different between the groups (P>0.05). BuCyE is a conditioning regimen which can be effectively used as an alternative to BEAM in the patients with malignant lymphoma undergoing ASCT. Moreover, toxicity rates of both regimens are

    Full Text Available AbstractBackground and Purpose: Pre-menstrual syndrome (PMS is one of the abnormalities associated with pre-menstrual cycles. Approximately 85% to 97% of women are suffering from psycho-somatic of physiological and behavioral symptoms from PMS, prior to menstruation. The most common PMS symptoms include: flatulence, stress anxiety, breast tenderness, depression, fatigue, unknown irritability, anger, poor concentration, and some degree in extremities edema. There are several therapeutic methods for PMS such as: oral contraceptive pills, GnRH antagonisms, diazole, use of Calcium and vitamin supplements, and dietary modification in which there is a controversy regarding type of diet. We assessed the effect of third- hour starch dietary regimen on pre-menstrual syndrome among high school students.Materials and Methods: This randomized quasi- experimental study was performed on students in grade 2 and 3 in Private and Governmental high schools in Sari. The sample size was calculated using randomize numbers table (478 participants. A questionnaire composed of two parts was prepared. The first part included demographic characteristics, while the second part consisted of data related to history of menstrual cycle, pervious diseases and use of drugs. The symptoms of PMS were assessed at the beginning of the study and also at the end of the first, second and third month after beginning of the third-hours starch regimen. Data was gathered by self-reporting technique, analyzed by descriptive and comprehensive statistical techniques.Results: The age range of participants was 14 to 19 years of age (16.891.12. The mean of menstrual cycle was 28.872.1 days, and the mean of menstrual duration was 6.321.8.

El objetivo secundario del estudio fue determinar factores predictores de persistencia. Material y métodos: Estudio observacional retrospectivo que incluyo los siguientes criterios: pacientes VIH+ con tratamiento antirretroviral (TAR) con un regimen basado en STR o LDR. Se recogieron variables demograficas, factores de riesgo de adquisicion, consumo de drogas, presencia de algun trastorno psiquiatrico y coinfeccion por el virus de la hepatitis B o C. Para comparar la persistencia entre ambas estrategias se realizo un analisis de supervivencia de Kaplan-Meir y se aplico el metodo de log-rank. Se realizo un analisis de regresion de Cox para identificar los factores predictores de persistencia. Resultados: Se incluyeron 244 pacientes, 176 con STR y 68 con LDR. El 34,1% (n = 60) de los pacientes que recibieron un regimen STR abandonaron y en el LDR el 19,1% (n = 13). Los efectos adversos fueron la principal causa de abandono del tratamiento en los pacientes que recibieron STR y el fallo virologico en el regimen LDR. La persistencia de las estrategias STR y LDR fue similar, no encontrandose diferencias estadisticamente significativas entre ambas. El consumo de drogas fue el unico factor predictivo asociado con una menor persistencia (HR = 2,59; p = 0,005). Conclusiones: La persistencia entre los regimenes STR y LDR fue similar, no detectandose diferencias significativas entre ambos. El consumo de drogas fue el unico factor independiente asociado con una menor persistencia del tratamiento antirretroviral.

    Multiple chemotherapy regimens are available for the treatment of metastatic pancreas cancer (mPCA). Choice of regimen is based on the patient's performance status and toxicity profile of the regimen. The objective of this study was to analyze the costs of first-line regimens to further aid in decision-making and develop a platform upon which to assess value. We calculated the monthly cost for individual standard regimens (gemcitabine, gemcitabine/nab-paclitaxel, gemcitabine/erlotinib and FOLFIRINOX) and the overall treatment cost for a course of therapy based on the median progression-free survival achieved in published studies. In addition to cost of drugs, we included administration costs and costs of toxicities (including growth factor support, blood product transfusion and hospitalization for toxicities). Costs for administration and management of adverse events were based on Medicare reimbursement rates for hospital and physician services. Drug costs were based on Medicare average sale prices (all 2014 US$). The monthly costs for gemcitabine, FOLFIRINOX, gemcitabine/erlotinib and gemcitabine/nab-paclitaxel were $1363, $7234, $8007 and $12,221, respectively. The overall treatment costs for a course of the same regimens based on median PFS were $5043, $46,298, $51,004 and $67,216, respectively. The choice of chemotherapy regimen for mPCA should be based on tolerability and efficacy of the regimen individualized to patient's performance status. Healthcare systems have finite resources; thus, there is increasing emphasis on metrics to define value in health care when outcomes of therapy are similar or produce marked differences in value. These data provide useful financial information to incorporate into the decision-making process. PMID:27067436

    The aim of this simulation study was to evaluate the ability of three regimens proposed in official French recommendations for gentamicin to hit defined pharmacokinetic (PK) and pharmacodynamic targets in a population of elderly patients. The first drug regimen tested consisted of a loading dose of 1 mg/kg and a maintenance dose weighted by creatininemia, every 8 h. The second regimen consisted of a fixed dose of 1 mg/kg at various intervals of time, calculated from creatinine clearance. The last regimen was a fixed dose of 3 mg/kg once a day. All regimens were for 5 days. We used a bicompartmental PK model and implemented a Monte Carlo simulation to generate a large sample of geriatric subjects. The analysis examined three ranges of creatinine clearance. Simulations showed that for the two regimens using multiple doses per day, neither was able to reach an efficacy level without significant toxicity after 5 days of treatment, regardless of the level of renal function. The use of creatininemia or creatinine clearance to adjust the drug dose did not alter these findings. The once-a-day dosing regimen gave better results both in efficacy and toxicity, except for patients with creatinine clearance lower than 60 mL/min, where the incidence of potential toxicity was above 25%. These results strongly suggest that official French recommendations about aminoglycoside dosage regimens in elderly patients with renal impairment should be updated, and that the frequent need for therapeutic drug monitoring and dosage individualization should be clearly stated.

Urine samples were collected at baseline and daily to determine the concentrations of kidney injury molecule 1 (KIM-1), a marker for early kidney injury. When a clinically relevant exposure of telavancin was given daily to rats, some differences in kidney injury were attributed to the dosing regimen. Further investigations of alternative telavancin dosing regimens are warranted.

    Objective: To develop agents that are specifically effective in controlling the key disturbance of visceral hyperalgesia besides abating of associated multiple symptoms, and evaluate comparative effectiveness for IBS symptom relief for standard regimen (antispasmodic and probiotic) and add-on amitriptyine or riluzole regimens following two weeks administration.Methods:groups were studied. First group received standard treatment (mebeverine 200 mg twice daily and probiotic 200 mg twice daily). Second group received add-on amitriptyline 25 mg before bedtime, while the third group got add-on riluzole 50 mg twice daily. Overall gastrointestinal symptom rating scale improving symptoms and hospital anxiety depression scale improving associated psychological morbidity were employed as measures at induction and at two-week follow-up period. Individual symptom scores were also examined to define the outcome profiles.Results:108 patients with visceral hypersensitivity accompanying IBS, divided into three rating scale score, not the other two regimens. Pain relief was seen with both riluzole and amitriptyline regimens significantly superior to standard treatment regimen, but riluzole effect appeared specific and independent anxiolytic effect. Amitriptyline caused relief in diarrhea and did not benefit in constipation point to non-specific remedial role in IBS. Riluzole regimen resulted in significant reduction of overall gastrointestinal symptom Conclusions: Riluzole specifically relieves visceral hypersensitivity and is proved to be superior to current treatments in IBS patients. It appears a lead remedy based on glutamate transporter mechanisms in visceral hypersensititvity.

    Cereblon (CRBN) has been identified as a primary target of immunomodulatory drugs and is considered a biomarker for the prediction of outcomes after thalidomide- or lenalidomide-based treatments. In this study, we evaluated CRBN expression in bone marrow (BM) tissue at diagnosis and investigated the relationship between CRBN expression and treatment outcomes after thalidomide- or bortezomib-based front-line therapies in 89 elderly patients with multiple myeloma (MM). CRBN expression at the time of diagnosis was evaluated with immunohistochemical (IHC) staining for myeloma cells in paraffin wax-embedded BM tissue. CRBN-immunostained slides were scored by intensity and diffuseness, and a total score of >6 was defined as CRBN-positive (CRBN(+)). Thirty-eight patients (45.2 %) were CRBN(+). Among patients treated with thalidomide-based regimens, CRBN(+) patients showed a better treatment response than did CRBN-negative patients (35.0 vs. 11.8 % complete response rate, respectively; HR = 4.038, P = 0.137). During a median follow-up of 31.8 months, patients treated with bortezomib-based regimens had a longer time to progression (TTP) than did patients treated with thalidomide-based regimens (15.6 vs. 13.2 months, respectively; P = 0.047), but early mortality occurred frequently in patients treated with bortezomib-based regimens. Additionally, there was no significant difference in survival outcomes between thalidomide- and bortezomib-based regimens in CRBN(+) patients (median TTP, 13.8 vs. 15.6 months, respectively; P = 0.842 and median OS, 39.3 vs. 30.1 months, respectively; P = 0.074). These data suggest that thalidomide-based regimens are as effective as bortezomib-based regimens in elderly patients with MM who are CRBN(+). Thus, CRBN positivity, by IHC staining, may be useful in deciding appropriate treatment options in elderly patients with MM. PMID:27365142

    In order to have an adequate view of the whole small intestine during capsule endoscopy,the preparation recommended consists of a clear liquid diet and an overnight fast.However,visualization of the small bowel during video capsule endoscopy can be impaired by intestinal contents.To improve mucosal visualization,some authors have evaluated different regimens of preparation.There is no consensus about the necessity of intestinal preparation for capsule endoscopy and it should be interesting to develop adequate guidelines to improve its efficacy and tolerability.Moreover,the effect of preparation type (purgative) on intestinal transit time is not clear.Since a bowel preparation cannot definitively improve its visibility (and theoretically the yield of the test),it is not routinely recommended.

    Allogeneic hematopoietic stem cell transplantation remains the sole curative option for myelofibrosis. Many transplantation recipients receive a reduced-intensity conditioning (RIC) regimen owing to age or comorbidities; however, there is little published evidence to guide the choice of RIC regimen. In this study, we compared outcomes in patients who received 1 of 2 frequently used RIC regimens for patients with myelofibrosis: fludarabine-busulfan (FB) and fludarabine-melphalan (FM). A total of 160 patients underwent a RIC allograft procedure (FB group, n = 105; FM group, n = 55). We have developed a complex statistical model involving weighting and adjustment to permit comparison between these 2 groups. After weighting, the incidence of acute graft-versus-host disease (GVHD) was 62% in the FM group and 31% in the FB group (P = .001), and the corresponding incidence of chronic GVHD was 49% and 53%, respectively. The 7-year progression-free survival was were 52% in the FM group versus 33% in the FB group, and the 7-year overall survival rate 52% in the FM group versus 59% in the FB group. Nonrelapse mortality (NRM) was 43% in the FM group and 31% in the FB group. Multivariable analyses revealed no significant differences in PFS between the 2 groups; however, the relapse rate was significantly lower in the FM group (hazard ratio, 9.21; P = .008), whereas a trend toward reduced NRM was seen in the FB group (hazard ratio, 0.51; P = .068). In conclusion, both regimens appear to be efficient in mediating disease control and can be used to successfully condition patients with myelofibrosis. The FM regimen appears to induce more NRM than the FB regimen, but with augmented control of disease, leading to comparable overall survival rates for both regimens.

    Modern insulin regimens for the treatment of type 1 diabetes are highly individualized. The concept of an individually tailored medicine accounts for a broad variety of different insulin regimens applied. Despite clear recommendations for insulin management in children and adolescents with type 1 diabetes there is little distinctiveness about concepts and the nomenclature is confusing. Even among experts similar terms are used for different strategies. The aim of our review--based on the experiences of the Hvidoere Study Group (HSG)--is to propose comprehensive definitions for current insulin regimens reflecting current diabetes management in childhood and adolescence. The HSG--founded in 1994--is an international group representing 24 highly experienced pediatric diabetes centers, from Europe, Japan, North America and Australia. Different benchmarking studies of the HSG revealed a broad variety of insulin regimens applied in each center, respectively. Furthermore, the understanding of insulin regimens has been persistently different between the centers since more than 20 yr. Not even the terms 'conventional' and 'intensified therapy' were used consistently among all members. Besides the concepts 'conventional' and 'intensified', several other terms for the characterization of insulin regimens are in use: Basal Bolus Concept (BBC), multiple daily injections (MDI), and flexible insulin therapy (FIT) are most frequently used, although none of these expressions is clearly or consistently defined. The proposed new classification for insulin management will be comprehensive, simple, and catchy. Currently available terms were included. This classification may offer the opportunity to compare therapeutic strategies without the currently existing confusion on the insulin regimen.

    A multicenter comparative study was carried out to investigate the efficacy and safety of hematopoietic stem cell transplantation with conditioning regimens containing melphalan in pediatric patients with acute lymphoblastic leukemia. One hundred twenty three patients at a variety of remission stages were eligible for study participation. Eighty-nine were transplanted with allogeneic grafts and 34 patients with autologous grafts (23 cases with bone marrow and 11 cases with peripheral blood stem cells). Conditioning regimens used were as follows: melphalan and busulfan for 40 patients, melphalan, busulfan and TBI for 44 patients, other regimens for 39 patients. To accelerate engraftment G-CSF (lenograstim) was administered as a 1-hour or 24-hour drip infusion daily at 5 {mu}g/kg from day 5 until hematological recovery. The five year disease free survival (DFS) was 63% for 42 patients at CR1, 41% for 41 patients at CR2 and 33% for 40 patients at other stages. There was no significant difference in the DFS between allogeneic-transplantation and autologous-transplantation in all disease stages. In patients at remission stage for CR1 and CR2, the 5-year DFS by conditioning regimen was 63% for regimen with melphalan and busulfan, 54% for regimen with melphalan, busulfan and TBI and 54% for regimens with melphalan and TBI. There was no significant difference in the DFS between the groups. Serious complications such as renal failure were observed in 11%, veno-occlusive disease in 9%, and interstitial pneumonia in 9%. The most dominating cause of death was relapse in the disease (48% of deaths) which was most commonly observed in autologous transplantation. Contrary to that, treatment related toxic death was the most frequent cause of deaths in allogeneic-transplantation. (author)

    Purpose: To exam the relationship between HER2 over-expression and different adjuvant chemotherapies in breast cancer. Patients and Methods: A total of 1625 primary breast cancer patients who received post-surgery adjuvant chemotherapy in Tianjin Cancer Hospital, China, from July 2002 to November 2005 were included in the study. Among them, 600 patients were given CMF (CTX+MTX+5-Fu) regimen, 600 given CEF (CTX+E-ADM+5-Fu) regimen, and 425 given anthracyclines plus taxanes regimen, with mean follow-up time of 42 months. Results: In CMF treatment group, the 3-year disease free survival (DFS)in HER2 over-expressed patients was lower than that of the HER2-negative ones (89.80% vs 91.24%, P=0.0348); in node-positive subgroup, the 3-year DFS was 84.72% in HER2 over-expressed patients, and 90.18% in the HER-2-negative ones (P=0.0271).Compared to CMF regimen, anthracyclines and anthracyclines plus taxanes regimens are more effective (P<0.05) in node-positive HER2 over-expression than those in the node-negative. Conclusion: HER2 over-expression is an independent index for predicting poor prognosis and short DFS for breast cancer patients. HER2 over-expressed patients are resistant to CMF regimen chemotherapy, but sensitive to anthracyclines-based or anthracyclines plus taxanes regimen. HER2 expression can be taken as a marker for therapies in breast cancer.

    The standard therapy for preventing copper accumulation in Wilson's disease, D-penicillamine, has been a life-saving drug, but it has many side effects and some patients are completely intolerant. We have been using oral zinc as another approach to the therapy for Wilson's disease, with copper balance studies as the key initial assessment of the adequacy of a given dose or regimen of zinc therapy. We earlier reported that an intensive regimen of zinc (zinc taken every 4 hr) was effective in controlling copper balance. We have now shown with balance studies that a simplified zinc therapy regimen of 50 mg zinc taken 3 times per day is effective in controlling copper balance. Preliminary work presented here with other simplified regimens also indicate their effectiveness. These studies increase the data base, in terms of copper balance, for zinc therapy of Wilson's disease, and expand the dose range and regimens of zinc which have been shown to control copper balance.

    Full Text Available Background: The entire effects of different bleaching regimens on the mechanical properties of composite resins have remained unknown. The purpose of this study was to evaluate the effects of different bleaching regimens on the flexural strength (FS of hybrid composite resins. Materials and Methods: In this in vitro study, 80 bar-shaped specimens of hybrid composite resins were fabricated and randomly divided into four groups, 20 specimens in each group. First group (C was considered as control. The other groups were treated by home bleaching (HB agent, in-office bleaching (IB agent, and the combination regimens (HIB, respectively. The FS was evaluated by three-point bending test by using a Universal Testing Machine. All data were analyzed by using Statistical Package for the Social Sciences (SPSS software version 18, analysis of variance (ANOVA, and Turkey′s post hoc statistical tests (α = 0.05. Results: The maximum mean value of FS was seen in HB group with significant differences to other groups (P < 0.05. Also, the minimum FS was observed in group HIB. Conclusion: Application of different bleaching regimens does not have any adverse effect on the FS of hybrid composite resins. However, the administration of HB regimens seemed to have lesser negative impact on the FS.

    Pharmacokinetic estimation for therapeutic dosage regimens (PETDR) is a soft-ware program used to design individualized intravenous dosage regimens, determine concentration-time profiles, predict serum concentrations at a specific time after intravenous dosing and predict the time after the last dose to achieve a specified concentration of drug. The reference pharmacokinetic parameters may be based on an individual animal's pharmacokinetic disposition of drug or on FARAD (Food Animal Residue Avoidance Databank) mean population kinetic parameters. An individual animal's kinetic parameters may be input for predetermined analysis or the program can calculate these values by input of raw serum concentration-time data. The program allows the user to specify certain parameters of the dosage regimen, then calculates the other parameters (given desired maximum and minimum serum concentrations, dose and interval are calculated; given desired maximum serum concentration and interval, dose is calculated, etc.). Given the kinetic parameters, the dose and dosing interval, the program calculates and plots the serum concentration-time profile of the drug for that animal. The time and the number of doses to reach steady state can be calculated as well as the determination of loading dose. The percentage of the time of a dosing interval at steady state that the serum concentration is above a specific minimum inhibitory concentration (MIC) allows evaluation of efficacy of an antimicrobial regimen. Similarly, the time to reach a specific concentration (e.g. residue tolerance) or the MIC of a drug can be calculated. Legal tissue tolerances can be accessed from FARAD to aid in predicting for what period of time illegal residues will remain in the animal.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3210265

    Full Text Available A prospective study was conducted on 79 advanced immunosuppressed AIDS patients from 1997 to 1999, during which nine cases of tuberculosis (TB were diagnosed. The main clinical and laboratory characteristics and the response to TB treatment were reviewed. The clinical manifestations of TB were: pulmonary (six cases, extrapulmonary (two cases and disseminated (one case. These patients were being treated with highly active antiretroviral treatment (HAART and were not responding. In three cases an optional regimen without rifampicin (RMP was indicated to maintain HAART during TB treatment. A clinical response to TB treatment (disappearance of fever was observed in 6/9 patients during a mean of 73 days (SD = 96. The three unresponsive patients were those treated without RMP. A switch to TB regimens containing RMP was proposed and successful. In our study, though it was limited by a small sample size, the response to TB regimens without rifampin was poor in immunossupressed patients failing HAART.

    Episodes of human immunodeficiency virus low-level viremia (LLV) are common in the clinical setting, but its association with antiretroviral therapy (ART) regimen and adherence remains unclear. Antiretroviral therapy adherence was evaluated in participants of the Research on Access to Care in the Homeless cohort by unannounced pill counts. Factors associated with increased risk of LLV include treatment with a protease inhibitor (PI)-based regimen (ritonavir-boosted PI vs nonnucleoside reverse-transcriptase inhibitor: adjusted hazard ratio [HR], 3.1; P = .01) and lower ART adherence over the past 3 months (HR, 1.1 per 5% decreased adherence, adjusted; P = .050). Patients with LLV may benefit from ART adherence counseling and potentially regimen modification. PMID:25884007

    Treatment guidance for non-multidrug-resistant (MDR) rifampicin-resistant (RMP-R) tuberculosis (TB) is variable. We aimed to undertake a systematic review and meta-analysis of the randomised controlled trial (RCT) data behind such guidelines to identify the most efficacious treatment regimens. Ovid MEDLINE, the Web of Science and EMBASE were mined using search terms for TB, drug therapy and RCTs. Despite 12 604 records being retrieved, only three studies reported treatment outcomes by regimen for patients with non-MDR RMP-R disease, preventing meta-analysis. Our systematic review highlights a substantial gap in the literature regarding evidence-based treatment regimens for RMP-R TB.

    Full Text Available RATIONALE: The sterilizing activity of the regimen used to treat multidrug resistant tuberculosis (MDR TB has not been studied in a mouse model. OBJECTIVE AND METHODS: Swiss mice were intravenously inoculated with 6 log10 of Mycobacterium tuberculosis (TB strain H37Rv, treated with second-line drug combinations with or without the diarylquinoline TMC207, and then followed without treatment for 3 more months to determine relapse rates (modified Cornell model. MEASUREMENTS: Bactericidal efficacy was assessed by quantitative lung colony-forming unit (CFU counts. Sterilizing efficacy was assessed by measuring bacteriological relapse rates 3 months after the end of treatment. MAIN RESULTS: The relapse rate observed after 12 months treatment with the WHO recommended MDR TB regimen (amikacin, ethionamide, pyrazinamide and moxifloxacin was equivalent to the relapse rate observed after 6 months treatment with the recommended drug susceptible TB regimen (rifampin, isoniazid and pyrazinamide. When TMC207 was added to this MDR TB regimen, the treatment duration needed to reach the same relapse rate dropped to 6 months. A similar relapse rate was also obtained with a 6-month completely oral regimen including TMC207, moxifloxacin and pyrazinamide but excluding both amikacin and ethionamide. CONCLUSIONS: In this murine model the duration of the WHO MDR TB treatment could be reduced to 12 months instead of the recommended 18-24 months. The inclusion of TMC207 in the WHO MDR TB treatment regimen has the potential to further shorten the treatment duration and at the same time to simplify treatment by eliminating the need to include an injectable aminoglycoside.

Predicting HIV resistance would be much easier, but unfortunately we rarely have enough structural information available to train a neural network. To network model designed to predict how long the HIV patient can prolong his/her life time with certain regimen specification. To learn this model 300 patient's details have taken as a training set to train the network and 100 patients medical history has taken to test this model. This network model is trained using MAT lab implementation.

    High-dose etoposide is used in conditioning regimens for allogeneic stem cell transplantation. The limited stability of the drug induces barriers for its use for pharmacists, nurses and patients. When using a concentration of 10 mg/mL etoposide in physiologic saline, limitations can be overcome. This study provides stability data for etoposide in a high concentration that can be used in conditioning regimens. The solution was stable for 48h at 5°C, for 48h at 5°C followed by 8h at 25°C and for 24 h at 25°C.

    Abstract Objective: To compare regimens consisting of either ritonavir-boosted atazanavir or efavirenz and a nucleoside reverse transcriptase inhibitor (NRTI) backbone with respect to clinical, immunologic, and virologic outcomes. Design: Prospective studies of human immunodeficiency virus (HIV)-infected individuals in Europe and the United States included in the HIV-CAUSAL Collaboration. Methods: HIV-positive, antiretroviral therapy-naive, and acquired immune deficiency syndrome (AIDS)-free individuals were followed from the time they started an atazanavir or efavirenz regimen. We estimated an analog of the “intention-to-treat” effect for efavirenz versus atazanavir regimens on clinical, immunologic, and virologic outcomes with adjustment via inverse probability weighting for time-varying covariates. Results: A total of 4301 individuals started an atazanavir regimen (83 deaths, 157 AIDS-defining illnesses or deaths) and 18,786 individuals started an efavirenz regimen (389 deaths, 825 AIDS-defining illnesses or deaths). During a median follow-up of 31 months, the hazard ratios (95% confidence intervals) were 0.98 (0.77, 1.24) for death and 1.09 (0.91, 1.30) for AIDS-defining illness or death comparing efavirenz with atazanavir regimens. The 5-year survival difference was 0.1% (95% confidence interval: −0.7%, 0.8%) and the AIDS-free survival difference was −0.3% (−1.2%, 0.6%). After 12 months, the mean change in CD4 cell count was 20.8 (95% confidence interval: 13.9, 27.8) cells/mm3 lower and the risk of virologic failure was 20% (14%, 26%) lower in the efavirenz regimens. Conclusion: Our estimates are consistent with a smaller 12-month increase in CD4 cell count, and a smaller risk of virologic failure at 12 months for efavirenz compared with atazanavir regimens. No overall differences could be detected with respect to 5-year survival or AIDS-free survival. PMID:27741139

    Full Text Available This article contains analysis of current combination treatment regimens for chronic hepatitis C after liver transplantation. Antiviral therapy with long-acting interferons and ribavirin is of low efficiency and high costs. The clinical and economic benefits of interferon-free treatment regimen for patients infected with genotype 1 HCV using dasabuvir, paritaprevir boosted with ritonavir, ombitasvir (Viekira Pak and ribavirin have been shown. Registration and introduction into clinical practice of new direct-acting antiviral drugs will significantly expand the arsenal of tools for the treatment of recurrent HCV infections, in particular in patients infected with hepatitis C virus genotypes 2 and 3.

The comparisons were performed with the help of a Markov decision model over a 10-year time horizon. Based on the ADONE (ADherence to ONE pill study, it was then possible to identify the utility score increment in patients switching from a multipill regimen of TDF-FTC + EFV therapy to a single-tablet regimen.Results: The single-tablet regimen (0.755 quality-adjusted life-years [QALYs]/year resulted in better patient quality of life, with a higher number of QALYs than for the TDF-FTC + EFV multipill regimen (0.716 QALYs/year. The single-tablet regimen was the most cost-effective treatment strategy, with an incremental cost-effectiveness ratio of €22,017.00 versus €26,558.00 for the multipill regimen. A 24% decrease in cost of the multipill regimen determined equivalence with the single-tablet regimen in terms of the incremental cost-effectiveness ratio. Univariate sensitivity and probabilistic analysis carried out on the main variables did not highlight significant variations with respect to the base case scenario.Conclusion: The single-tablet regimen resulted in better adherence, and therefore better quality of life as perceived by patients, corresponding to a €4541.00 lower

    Full Text Available Background: Pemphigus has been treated with Dexamethasone Cyclophosphamide Pulse (DCP Therapy since 1981.Various modifications have been suggested in the original regimen. These include Dexamethasone Azathioprine Pulse (DAP and Dexamethasone Methotrexate Pulse (DMP therapies. Aims: To report our experience on the noncomparative study of various Pulse regimens DCP, DAP AND DMP therapies in patients with Pemphigus. Materials and Methods: The patients were put on three regimens depending upon the situation-Conventional DCP, DAP in the reproductive age group, DMP in patients who showed prolonged Phase I more than 12 months while on DCP. Results: 30 patients were put on DCP therapy. The duration of phase I was on an average six months. Relapse was seen in 3 patients in phase IV. 12 patients on DAP therapy were considered. In Phase III 5 patients relapsed in phase IV four patients relapsed. Five patients were put on the DMP. Disease activity was poorly controlled and in three DMP was discontinued. Conclusion: DCP remains the most effective regimen with quickest onset of remission and continuance of remission. In DAP therapy fixation of dose of azathioprine at 50 mgs daily may be counterproductive. DMP does not fulfil the promise of a viable treatment option in recalcitrant pemphigus and this lacunae needs to be plugged.

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

    This study was designed to test the hypothesis that there are regimen-specific differences in the thermal, metabolic, and cardiovascular responses of nonpregnant women when they perform their chosen type of aerobics at their usual performance level. Thirty-six instructors and 53 participants were studied while performing their chosen aerobics regimen under simulated field conditions using oxygen consumption as the index of exercise intensity. Under these conditions no significant differences were observed in the physiological response to low impact, high impact, or step regimens. However, although their ratings of perceived exertion were lower, the participants worked at a much higher exercise intensity than the instructors (76 +/- 1 vs 62 +/- 2% VO2max). As a result they attained a higher respiratory exchange ratio (0.96 vs 0.90), rectal temperature (38.62 vs 38.12 degrees C), and blood levels of glucose (5.70 vs 4.95 mmol.l-1), lactate (3.65 vs 1.60 mmol.l-1), and norepinephrine (2656 vs 1191 pg.ml-1). We conclude that both intensity and physiological response to aerobics are individual specific not regimen specific and that participants consistently underestimate their level of performance.

    Full Text Available Abstract Indolent lymphoma (IL, the second most common lymphoma, remains incurable with chemotherapy alone. While R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone remains the standard frontline regimen for diffuse Large B –cell lymphoma, the optimal chemotherapy regimen for frontline therapy of advanced IL remains uncertain. FCR (fludarabine, cyclophosphamide, rituximab has been shown to be better than fludarabine alone and fludarabine plus cyclophosphamide for IL. In FOLL05 trial, R-CHOP was compared with R-CVP (cyclophosphamide, vincristine, prednisone and R-FM (fludarabine, mitoxantrone. The study showed that R-CHOP appears to have the best risk-benefit ratio for IL. The StiL NHL1 trial showed that BR (bendamustine, rituximab has longer progression free survival and is better tolerated than R-CHOP. Long-term complications with secondary malignancies between the two regimens appear to be comparable. In this review, new combination regimens reported at 2012 ASCO annual meeting were evaluated for frontline and salvage therapy of indolent lymphoma.

    The aim of this study is to explore the efficacy of the 3C therapeutic regimen for type 1 diabetes. Thirty-nine patients with type 1 diabetes, who were hospitalized from January 2013 to April 2014, were included to receive 3C therapeutic regimen. Evidence-based nursing was performed in the treatment period and the efficacy was observed 6 days after therapy. Six days after the administration of the 3C therapeutic regimen, the fasting glucose levels in all 39 patients were controlled to be 4.4-6.0 mmol/L and 2h-postprandial glucose levels to be 4.4-7.8 mmol/L. Three patients had a glucose level <3.9 mmol/L, which was corrected after adjusting the dose of insulin infusion. Evidence-based nursing was provided in the treatment period and no nursing-associated complication occurred. All patients were satisfied with the nursing service. The efficacy of the 3C therapeutic regimen for type 1 diabetes is satisfactory. The evidence-based nursing can help to ensure the efficacy and improve the quality of nursing service. PMID:25424358

    To investigate the best first-line chemotherapy regimen for the treatment of advanced epithelial ovarian cancer (AEOC), the efficacy of three chemotherapy regimens for treatment of the patients with AEOC in our hospital during Jan. 1992- Jan. 1999 was retrospectively analyzed. The therapeutic effects were compared with the supplement of Melphalan + Hexamethylme (PAM + HMM), cisplatin + adriamycin +cyclophosphamide or isofamide (PAC) or cisplatin + cyclophosphamide or isofamide (PC), Taxol+cisplatin (TP) combined chemotherapy after cytoreductive surgery. The results showed that the overall effective rate of TP was significantly higher than that of PAM+ HMM (P<0. 05); The complete remission rate of TP was significantly higher than that of PAM+ HMM and PAC or PC (all P<0.05);The 2-year survival rate free of tumor of TP was obviously higher than that of PAM+HMM and PAC or PC(all P<0. 05). It was concluded that the therapeutic effect of TP regimen in the treatment of AEOC was better than PAM +HMM and PAC or PC and TP regimen could be recommended currently as the preferred first-line one for the treatment of AEOC.

    Patients with resistant hypertension (RH) are at greater risk for stroke, renal insufficiency, and cardiovascular disease (CVD) events than are those for whom blood pressure (BP) is responsive to and well controlled by therapeutic interventions. Although all chronotherapy trials have compared the effects on BP regulation of full daily doses of medications when ingested in the morning versus at bedtime, prescription of the same medications in divided doses twice daily (BID) is frequent. Here, we investigated the influence of hypertension treatment-time regimen on the circadian BP pattern, degree of BP control, and relevant clinical and laboratory medicine parameters of RH patients evaluated by 48-h ambulatory BP monitoring (ABPM). This cross-sectional study evaluated 2899 such patients (1701 men/1198 women), 64.2 ± 11.8 (mean ± SD) yrs of age, enrolled in the Hygia Project. Among the participants, 1084 were ingesting all hypertension medications upon awakening (upon-awakening regimen), 1436 patients were ingesting the full daily dose of ≥1 of them at bedtime (bedtime regimen), and 379 were ingesting split doses of ≥1 medications BID upon awakening and at bedtime (BID regimen). Patients of the bedtime regimen compared with the other two treatment-time regimens had lower likelihood of microalbuminuria and chronic kidney disease; significantly lower albumin/creatinine ratio, glucose, total cholesterol, and low-density lipoprotein (LDL) cholesterol; plus higher estimated glomerular filtration rate and high-density lipoprotein (HDL) cholesterol. The bedtime regimen was also significantly associated with lower asleep systolic (SBP) and diastolic (DBP) BP means than the upon-awakening and BID regimens. The sleep-time relative SBP and DBP decline was significantly attenuated by the upon-awakening and BID regimens (p treatment-time regimen groups (80.5% and 77.3%, respectively) than in the bedtime regimen (54.4%; p treatment regimens, compared with the

    Full Text Available Background: As the long-term efficacy of antiretroviral therapy regimens is confirmed, we need to identify additional combinations with long-term safety and potency, while also favoring simplicity of administration. In this light, we have undertaken a review of the use of abacavir/lamivudine (Kivexa, KVX-based regimens using integrase or CCR5 inhibitors as the third agent. Methods: A retrospective chart review was undertaken, with informed patient consent. We identified all the patients in whom KVX was prescribed (following appropriate HLA-B5701 screening with either raltegravir (RGV or maraviroc (MVC as initial therapy or as a switch from another regimen for reasons other than virologic failure. Virologic efficacy over 48 weeks was evaluated, along with specific drug-associated toxicity, adherence, and regimen modifications. Results: A total of 38 patients (5 women were evaluated, 24 on KVX/RGV, 13 on KVX/MVC, 1 on KVX/RGV/MVC. This was used as initial therapy in drug-naïve subjects in three cases, and was selected as a modification of previous (current or not therapy in 35 cases. Switches included replacement of the third agent with RGV or MVC (n=13, replacement of the NRTI backbone with KVX (n=13 or both. In all cases, the change was implemented to address a current or previous medication-associated toxicity, most commonly to address jaundice (n=8, diarrhea (n=5 or reduced renal function (n=5. Patients were predominantly MSMs (n=17 or IDUs (n=13 with a mean baseline CD4 cell count of 363 cells/mm3, and plasma viral load of 46407 copies/mL (20 with full suppression at time of study entry. At 48 weeks, 34/38 (89% achieved or maintained full suppression, with a mean CD4 count of 553 cells/mm3. Virologic failure with the development of the M184V mutation was observed in 3/4 non-suppressed patients, and a loss of CCR5 tropism and RGV resistance were observed in one case each, all in the context of reduced adherence.

    Full Text Available Background: Outcomes of antiretroviral treatment have been documented in both developed and developing countries. It has been reported consistently that the treatment is associated with many adverse events. However, little is known about their impact on the quality of life, clinical management, and survival in children aged less than 6 years in Uganda.Objectives: The purpose of this study was to determine the prevalence of the adverse events of antiretroviral treatment, their impact on mortality and the change in regimens prescribed to children treated at Mildway Centre in Uganda.Method: A retrospective chart review was performed for children younger than 6 years, treated since the Mildway Centre was opened in 1999. In order to achieve a larger sample, the records of children treated from January 2000 to July 2005 were included in the study. A pre-tested data collection form was used to collate socio-demographic and clinical data of the patients. These included the documented adverse events, causes of death, stage of infection, duration of treatment, regimen prescribed, year of enrolment into the treatment program, as well as whether or not they were still alive. Descriptive statistics were used in the analysis of data.Results: Of the 179 children, the majority were males and had a median age of 4 years. The majority (58.8% of children had suffered from severe immune depression since they met the WHO clinical stage III and IV, 73.8% had a baseline CD4T of less than 15%. Four regimens were prescribed to the children. The most common was a regimen containing zidovudine, lamivudine, and nevirapine (34.6%, followed by a regimen containing stavudine, lamivudine, and nevirapine (27.9%. Eleven children (6.1% had their regimen changed, of which six (54.5% were due to adverse events.

    Full Text Available Aim: To compare the changes in microhardness of root dentin caused by two novel irrigation regimens with conventional irrigation. Materials and Methods: Forty extracted human permanent incisor teeth were selected. Decoronated roots were separated longitudinally to get 80 specimens that were embedded in autopolymerizing acrylic resin and grounded flat with silicon carbide abrasive papers. Of these, 60 root segments without any cracks or defects were selected and divided into four groups according to the irrigation regimen used (n = 15. Group I: 5% sodium hypochlorite (NaOCl + 17% ethylenediaminetetraacetic acid (EDTA + 0.2% chlorhexidine digluconate (CHX (conventional. Group II: 6% Morinda Citrifolia Juice + 17% EDTA (MCJ. Group III: 5% NaOCl + Q Mix 2 in 1 (QMix. Group IV: Distilled water (control. Irrigation regimens were performed for 5 minutes. Dentin microhardness was measured with a Vickers indenter under a 200-g load and a 20-s dwell time at the midroot level of root dentin. The data were analyzed using Kruskal Wallis test and Dunn′s multiple comparison tests. Results: A significant difference was seen in the median values of the four groups. The control group showed the least reduction in microhardness when comparison with the other groups. Except for Group III (Q Mix, the other groups that were tested (MCJ and conventional regimens showed statistically significant difference from the control group. Conclusion: Within the limitation of this study, it was concluded that NaOCl + Q Mix were least detrimental to root dentin microhardness when compared with MCJ and conventional irrigation regimens.

    Children with tuberculosis are treated with drug regimens copied from adults despite significant differences in antibiotic pharmacokinetics, pathology, and the microbial burden between childhood and adult tuberculosis. We sought to develop a new and effective oral treatment regimen specific to children of different ages. We investigated and validated the concept that target drug concentrations associated with therapy failure and death in children are different from those of adults. On that basis, we proposed a 4-step program to rapidly develop treatment regimens for children. First, target drug concentrations for optimal efficacy are derived from preclinical models of disseminated tuberculosis that recapitulate pediatric pharmacokinetics, starting with monotherapy. Second, 2-drug combinations were examined for zones of synergy, antagonism, and additivity based on a whole exposure–response surface. Exposures associated with additivity or synergy were then combined and the regimen was compared to standard therapy. Third, several exposures of the third drug were added, and a 3-drug regimen was identified based on kill slopes in comparison to standard therapy. Fourth, computer-aided clinical trial simulations are used to identify clinical doses that achieve these kill rates in children in different age groups. The proposed program led to the development of a 3-drug combination regimen for children from scratch, independent of adult regimens, in <2 years. The regimens and doses can be tested in animal models and in clinical trials. PMID:27742637

    2011-07-01

    Full Text Available Abstract Background Tafenoquine is an 8-aminoquinoline being developed for radical cure (blood and liver stage elimination of Plasmodium vivax. During monotherapy treatment, the compound exhibits slow parasite and fever clearance times, and toxicity in glucose-6-phosphate dehydrogenase (G6PD deficiency is a concern. Combination with other antimalarials may mitigate these concerns. Methods In 2005, the radical curative efficacy of tafenoquine combinations was investigated in Plasmodium cynomolgi-infected naïve Indian-origin Rhesus monkeys. In the first cohort, groups of two monkeys were treated with a three-day regimen of tafenoquine at different doses alone and in combination with a three-day chloroquine regimen to determine the minimum curative dose (MCD. In the second cohort, the radical curative efficacy of a single-day regimen of tafenoquine-mefloquine was compared to that of two three-day regimens comprising tafenoquine at its MCD with chloroquine or artemether-lumefantrine in groups of six monkeys. In a final cohort, the efficacy of the MCD of tafenoquine against hypnozoites alone and in combination with chloroquine was investigated in groups of six monkeys after quinine pre-treatment to eliminate asexual parasites. Plasma tafenoquine, chloroquine and desethylchloroquine concentrations were determined by LC-MS in order to compare doses of the drugs to those used clinically in humans. Results The total MCD of tafenoquine required in combination regimens for radical cure was ten-fold lower (1.8 mg/kg versus 18 mg/kg than for monotherapy. This regimen (1.8 mg/kg was equally efficacious as monotherapy or in combination with chloroquine after quinine pre-treatment to eliminate asexual stages. The same dose of (1.8 mg/kg was radically curative in combination with artemether-lumefantrine. Tafenoquine was also radically curative when combined with mefloquine. The MCD of tafenoquine monotherapy for radical cure (18 mg/kg appears to be biologically

    Reviewed in this statement are methods of preparing solutions to be used in laboratory experiments to examine technical issues related to the safe disposal of nuclear waste from power generation. Each approach currently used to prepare solutions has advantages and any one approach may be preferred over the others in particular situations, depending upon the goals of the experimental program. These advantages are highlighted herein for three approaches to solution preparation that are currently used most in studies of nuclear waste disposal. Discussion of the disadvantages of each approach is presented to help a user select a preparation method for his particular studies. Also presented in this statement are general observations regarding solution preparation. These observations are used as examples of the types of concerns that need to be addressed regarding solution preparation. As shown by these examples, prior to experimentation or chemical analyses, laboratory techniques based on scientific knowledge of solutions can be applied to solutions, often resulting in great improvement in the usefulness of results

  14. Modelling and analysis of the feeding regimen induced entrainment of hepatocyte circadian oscillators using petri nets.

    Directory of Open Access Journals (Sweden)

    Samar Hayat Khan Tareen

    Full Text Available Circadian rhythms are certain periodic behaviours exhibited by living organism at different levels, including cellular and system-wide scales. Recent studies have found that the circadian rhythms of several peripheral organs in mammals, such as the liver, are able to entrain their clocks to received signals independent of other system level clocks, in particular when responding to signals generated during feeding. These studies have found SIRT1, PARP1, and HSF1 proteins to be the major influencers of the core CLOCKBMAL1:PER-CRY circadian clock. These entities, along with abstracted feeding induced signals were modelled collectively in this study using Petri Nets. The properties of the model show that the circadian system itself is strongly robust, and is able to continually evolve. The modelled feeding regimens suggest that the usual 3 meals/day and 2 meals/day feeding regimens are beneficial with any more or less meals/day negatively affecting the system.

    2015-01-01

    This systematic review aims to assess irinotecan-based salvage regimens for patients with recurrent glioblastoma multiforme (GBM) beyond first line treatment. Eligible trials were identified using databases search and 25 studies were included in the final analysis. Among the 25 studies, PFS-6 rate was reported in 15 studies and it ranged from 16% to 63%. Median PFS was reported in 18 studies and it ranged from 1 to 7.6 months. While for median OS, it was reported in 17 studies and it ranged from 5.8 months to 17.9 months. The available data suggests that routine use of irinotecan-based salvage regimens cannot be recommended outside the setting of well-controlled prospective randomized studies investigating novel combinations of irinotecan.

    Full Text Available For full HIV virological suppression, three fully active antiretroviral agents are required. New drug classes should be included to ensure that agents are fully active. The addition of enfuvirtide and efavirenz to the present patient’s new antiretroviral regimen ensured that two fully active agents were in use in the setting of a moderate degree of nucleoside resistance and a high level of protease resistance, and where non-nucleoside reverse transcriptase inhibitors were still fully active. Both viral load and CD4 count responded favourably to this regimen. The patient received support from physicians and clinic staff in the introduction and use of enfuvirtide. To reduce injection site reactions, a needle-free injection system (Biojector proved effective.

  19. Intestinal microbiota of broiler chickens as affected by litter management regimens

    2016-05-01

    Full Text Available Poultry litter is a mixture of bedding materials and enteric bacteria excreted by chickens, and it is typically reused for multiple growth cycles in commercial broiler production. Thus, bacteria can be transmitted from one growth cycle to the next via litter. However, it remains poorly understood how litter reuse affects development and composition of chicken gut microbiota. In this study, the effect of litter reuse on the microbiota in litter and in chicken gut was investigated using 2 litter management regimens: fresh vs. reused litter. Samples of ileal mucosa and cecal digesta were collected from young chicks (10 days of age and mature birds (35 days of age. Based on analysis using DGGE and pyrosequencing of bacterial 16S rRNA gene amplicons, the microbiota of both the ileal mucosa and the cecal contents was affected by both litter management regimen and age of birds. Faecalibacterium, Oscillospira, Butyricicoccus, and one unclassified candidate genus closely related to Ruminococcus were most predominant in the cecal samples, while Lactobacillus was predominant in the ileal samples at both ages and in the cecal samples collected at day 10. At days 10 and 35, 8 and 3 genera, respectively, in the cecal luminal microbiota differed significantly in relative abundance between the 2 litter management regimens. Compared to the fresh litter, reused litter increased predominance of halotolerant/alkaliphilic bacteria and Faecalibacterium prausnitzii, a butyrate-producing gut bacterium. This study suggests that litter management regimens affect the chicken GI microbiota, which may impact the host nutritional status and intestinal health.

    Retention wires permanently bonded to the anterior teeth are used after orthodontic treatment to prevent the teeth from relapsing to pre-treatment positions. A disadvantage of bonded retainers is biofilm accumulation on the wires, which produces a higher incidence of gingival recession, increased pocket depth and bleeding on probing. This study compares in vivo biofilm formation on single-strand and multi-strand retention wires with different oral health-care regimens. Two-centimetre wires we...

    2012-01-01

    Full Text Available Background: Oncologists today are greatly concerned about the treatment of relapsed/refractory acute leukemia. FLANG regimen, combination of novantron, cytarabine, fludarabine, and granulocyte-colony stimulating factor, has been used in treatment of refractory/relapsed acute leukemia since 1990s. The present study has evaluated mortality and response rate of this regimen. Materials and Methods: In this study, 25 patients with refractory/relapsed acute leukemia aged 15-55 years underwent FLANG regimen at Seyed-Al-Shohada Hospital, Isfahan, Iran during 2008-2009. One month later, bone marrow samples were taken to evaluate the responsiveness to treatment. Participants were followed for a year. The data was analyzed by student-t and chi-square tests, logistic, and Cox regression analysis, and Kaplan-Meier curves in SPSS 19. Results: Out of the 25 patients, 8 patients (32% had acute lymphoblastic leukemia (5 refractory and 3 relapsed cases and 17 subjects had acute myeloid leukemia (7 refractory and 10 relapsed cases. According to the bone marrow biopsies taken one month after FLANG regimen, 10 patients (40% had responded to treatment. Five patients of the 10 responders underwent successful bone marrow transplantation (BMT. On the other hand, 13 patients (52%, who had not entered the CR period, died during the follow-up. Logistic regression analysis did not reveal any significant associations between disease type and responsiveness to treatment. Conclusion: This study indicated higher rates of unresponsiveness to treatment while its mortality rate was comparable with other studies. Overall, according to limitations for BMT (as the only chance for cure in Iran, it seems that FLANG therapy is an acceptable choice for these patients.

    The treatment of chronic hepatitis C is revolutionizing rapidly. The aim of this study is to review the efficacy and safety of daclatasvir (DCV)-containing all-oral regimens in clinical studies for chronic hepatitis C treatment. Using PubMed and search terms of 'DCV,' 'hepatitis C virus (HCV) treatment,' and 'HCV NS5A inhibitors,' literature on the clinical development of DCV, as well as abstracts presented at the April 2015 annual meeting of the European Association for the Study of the Liver (EASL) and November 2014 annual meeting of the American Association for the Study of Liver Diseases were reviewed. The final search was undertaken on 14 July 2015. With its potent antiviral activity to all HCV genotypes (GT) demonstrated in preclinical, phases 1-3 studies, DCV has been acting as a very competent team player in clinical trials of all-oral regimens. It is generally safe and well tolerated with a low genetic barrier to resistance and low potential for drug-drug interaction. Administered with a non-structural protein 3 (NS3) protease inhibitor (asunaprevir, ASV) with or without a non-nucleoside NS5B polymerase inhibitor (beclabuvir, BCV), or a nucleotide NS5B polymerase inhibitor (sofosbuvir, SOF), DCV is able to achieve greater than a 90-% HCV eradication rate in both treatment-naïve and treatment-experienced patients with GT 1. A triple combination regimen with DCV/ASV/BCV results in 100% sustained virologic response (SVR) rates in HCV GT 4 treatment-naïve subjects. DCV/SOF combination also had demonstrated up to 90-% SVR rates in GT 3-infected non-cirrhotic patients. The efficacy and safety of DCV-containing all-oral regimens highlight a new era of interferon-free therapy for chronic hepatitis C. PMID:26542068

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

    Directory of Open Access Journals (Sweden)

    George L Drusano

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

    Objective: The aim of our study was to investigate if common toxicities are correlated to objective response rate (ORR) in metastatic colorectal cancer (mCRC) patients treated by irinotecan based regimens. Methods: Univariate and multivariate logistic regression analyses were performed to evaluate correlations between common toxicities and binary ORR in 106 mCRC patients from a prospective cohort treated with irinotecan based regimens. Results: The most frequent severe toxicities (Grade 3/4) were as follows: neutropenia (27.4%), diarrhea (16.9%), leucopenia (12.6%), vomiting (3.2%) and thrombocytopenia (2.1%). Thrombocytosis was observed in 25 (26.3%) patients. ORR was 25.3%. Thrombocytopenia (P = 0.014), line of chemotherapy (P = 0.028) and thrombocytosis (P = 0.033) were correlated with ORR in univariate analysis. In multivariate analysis, thrombocytopenia (odds ratio [OR] = 8.600, 95% confidence interval [CI] = 1.705–43.385, P = 0.009) and first line chemotherapy (OR = 5.155, 95% CI = 1.153–23.256, P = 0.032) positively related to ORR. Conclusion: Throm-bocytopenia may be an indicator of ORR in mCRC patients treated by irinotecan plus 5-fluorouracil/capecitabine. Evidence is not strong enough to prove that irinotecan based regimens-induced diarrhea, leucopenia, neutropenia or vomiting is associ-ated with ORR.

  10. Effects of an overfeeding regimen--the affective component of the sweet sensation.

    In some isolated parts of North Africa, there persists an ancient Berber custom of imposing an overfeeding regimen on young girls before marriage, to achieve an obesity which is regarded as aesthetically pleasing. We have studied the effect of such a regimen, lasting 12--16 weeks, on blood lipids and on the affective reactions to sweet tastes in nine subjects. It is known that the pleasantness of alimentary cues i.e., the feeding behaviour, depends on the subject's nutritional state. Only three subjects gained weight (by 3,5 and 8 kg), in spite of the strong pressure to overeat. No change in plasma lipid concentrations were observed. Nevertheless, at the end of the regimen every subject showed a highly significant decrease in the rated pleasantness of sweet stimuli when they were tested fasting. However, the reduction in sweet pleasantness induced by ingestion of a 200 ml load of 1.4 M glucose solution was not changed by the overfeeding. Thus, pressure to overfeed can reduce hunger, as seen in the attractiveness of sweet foods in fasted subjects, without modifying glucose-induced satiety. PMID:6582799

    Essential thrombocythaemia (ET) is characterised by enhanced platelet generation and thrombosis. Once daily (od) aspirin incompletely inhibits platelet thromboxane (TX)A2 production in ET. A twice daily (bid) dosing is necessary to fully inhibit TXA2. Whether this dosing regimen affects in vivo prostacyclin (PGI2) biosynthesis is unknown. PGI2 biosynthesis was characterised in 50 ET patients on enteric-coated (EC) aspirin 100 mg od, by measuring its urinary metabolite, 2,3-dinor-6-keto-PGF1α (PGI-M). Moreover, in a crossover study 22 patients poorly responsive to standard aspirin based on serum TXB2 levels (≥4 ng/ml) were randomised to different seven-day aspirin regimens: EC aspirin 100 mg od, 100 mg bid, 200 mg od, or plain aspirin 100 mg od. PGI-M measured 24 hours after the last aspirin intake (EC, 100 mg od) was similar in patients and healthy subjects both on (n=10) and off (n=30) aspirin. PGI-M was unrelated to in vivo TXA2 biosynthesis, and not affected by EC aspirin 100 mg bid or 200 mg od as compared to EC 100 mg od. PGI2 biosynthesis in aspirin-treated ET patients appears unrelated to TXA2 biosynthesis, and not affected by an improved aspirin regimen, demonstrating its vascular safety for future trials.

    Food allergy can be considered a failure in the induction of oral tolerance. Recently, great interest has been focused on understanding the mechanisms and the contributing factors of oral tolerance development, hoping for new definitive interventions in the prevention and treatment of food allergy. Given that food processing may modify the properties and the nature of dietary proteins, several food processing methods could affect the allergenicity of these proteins and consequently may favour oral tolerance induction to food allergic children. Indeed, effective thermal food processing regimens of altering food proteins to reduce allergenicity have been recently reported in the literature. This article is mainly focused on the effect of selective thermal processing regimens on the main infant allergenic foods, with a potential clinical relevance on their allergenicity and therefore on oral tolerance induction. In the light of recent findings, the acquisition of tolerance in younger age and consequently the ability of young children to "outgrow" food allergy could be achieved through the application of selective thermal processing regimens on certain allergenic foods. Therefore, the ability of processed foods to circumvent clinical disease and at the same time to have an impact on the immune system and facilitate tolerance induction could be invaluable as a component of a successful therapeutic strategy. The opening in the new avenues of research in the use of processed foods in clinical practice for the amelioration of the impact on the quality of life of patients and possibly in food allergy prevention is warranted.

    Full Text Available Knowledge of bed bug development under varying conditions can lead to more sophisticated management techniques. Development rate, age and stage-specific life tables were compared for a laboratory strain (HS and field strain (ECL-05 of bed bug Cimex lectularius L. (Hemiptera: Heteroptera reared on two blood regimens: human or rabbit blood. Harlan and ECL-05 bed bugs reared on human blood had a life expectancy of 207 and 208 days respectively from the egg stage. Egg to adult development of HS bed bugs reared on human blood (~35 days was significantly longer than that of the ECL-05 strain (~33 days in the third, fourth, and fifth instars. The HS and ECL-05 bed bugs reared on rabbit blood had a life expectancy of 149 and 174 days respectively. Egg to adult development time of HS on rabbit blood (~52 days was significantly longer than ECL-05 (~37 days in every instar, and HS total life span was significantly shorter compared to ECL-05. Developmental differences based on strain and blood regimen suggest rabbit blood is an inferior blood source for colony maintenance, and strain has variable effects on bed bug development. Findings suggest that blood regimen should strongly be considered in bed bug colony maintenance.

    This paper describes a quality improvement project designed to decrease postoperative pain, decrease post-operative nausea and vomiting (PONV), decrease time in the recovery room, and increase patient satisfaction in adult ambulatory septoplasty patients using a multimodal, preemptive analgesic regimen. The project was conducted in a community hospital setting with nine operating rooms, and a twenty one bed recovery room. Project participants included certified registered nurse anesthetists, anesthesiologists, operating room nurses, recovery room nurses, and otolaryngology surgeons. Following a period of departmental education, adult patients scheduled for outpatient septoplasty surgery received a preoperative regimen of medications that included gabapentin, celecoxib, and acetaminophen. Using a pre-post test design, (intervention group n = 17, non-intervention group n = 17) data was collected from patient and analyzed using SPSS version 18.0. The change in practice resulted in a significant decrease in pain scores in the recovery room and on discharge from the recovery room. In addition, patients who received the preemptive regimen also required significantly fewer opioid medications and were ready to be discharged from the recovery room in less time. PMID:26753247

    The presence of concomitant diseases is an independentpredictive factor for non-Helicobacter pylori(H. pylori) peptic ulcers. Patients contracting concomitant diseases have an increased risk of developing ulcer disease through pathogenic mechanisms distinct from those of H. pylori infections. Factors other than H. pylori seem critical in peptic ulcer recurrence in end stage renal disease(ESRD) and cirrhotic patients. However, early H. pylori eradication is associated with a reduced risk of recurrent complicated peptic ulcers in patients with ESRD and liver cirrhosis. Resistances to triple therapy are currently detected using culture-based and molecular methods. Culture susceptibility testing before first- or second-line therapy is unadvisable. Using highly effective empiric first-line and rescue regimens can yield acceptable results. Sequential therapy has been included in a recent consensus report as a valid first-line option for eradicating H. pylori in geographic regions with high clarithromycin resistance. Two novel eradication regimens, namely concomitant and hybrid therapy, have proven more effective in patients with dual-(clarithromycin- and metronidazole-) resistant H. pylori strains. We aim to review the prevalence of and eradication therapy for H. pylori infection in patients with ESRD and cirrhosis. Moreover, we summarized the updated H. pylori eradication regimens.

    New regimens based on two or more novel agents are sought to shorten or simplify treatment of tuberculosis (TB). Pretomanid (PMD) is a nitroimidazole in phase 3 trials that has significant bactericidal activity alone and in combination with bedaquiline (BDQ) and/or pyrazinamide (PZA). We previously showed that the novel combination of BDQ+PMD plus the oxazolidinone sutezolid (SZD) had sterilizing activity superior to that of the first-line regimen in a murine model of TB. The present experiments compared the activity of different oxazolidinones in combination with BDQ+PMD with or without PZA in the same model. The 3-drug regimen of BDQ+PMD plus linezolid (LZD) had sterilizing activity approaching that of BDQ+PMD+SZD and superior to that of the first-line regimen. The addition of PZA further enhanced activity. Reducing the duration of LZD to 1 month did not significantly affect the activity of the regimen. Halving the LZD dose or replacing LZD with RWJ-416457 modestly reduced activity over the first month but not after 2 months. AZD5847 and tedizolid also increased the bactericidal activity of BDQ+PMD, but they were less effective than the other oxazolidinones. These results provide optimism for safe, short-course oral regimens for drug-resistant TB that may also be superior to the current first-line regimen for drug-susceptible TB. PMID:26503656

    Full Text Available Introduction: Raltegravir intensification is associated with an increase in 2-LTR episomal HIV DNA= circles, indicating a persistent low-level replication, in some individuals in ART with suppressed HIV RNA. We aimed at monitoring residual plasma HIV RNA and cellular HIV DNA in virologically suppressed patients switching to a raltegravir-based regimen. Materials and Methods: Forty-six HIV-infected subjects on PI or NNRTI based-regimens, with plasma HIV RNA level 200 cells/µL for ≥12 months were enrolled. Thirty-four patients switched to raltegravir-based regimen (RASTA study group and 12 continued a PI or NNRTI based-regimen (control group. Ultrasensitive HIV residual viremia and total PBMC HIV DNA were assessed at baseline (W0, 24 (W24 and 48 (W48 weeks. HIV RNA levels were determined by an ultrasensitive test derived from a commercial real time PCR (limit of detection 5 copies/ml. A real time PCR was used to quantify HIV DNA copy numbers in PBMCs. Results: At W0, HIV DNA was detected in all patients while at W48 it was detectable in 82.3% of RASTA group vs 100% of controls (p=0.01. The difference between the average values of HIV DNA log10 copies/10°6 CD4 at W0 (median 3.11, IQR 2.70–3.45 and W48 (median 2.87, IQR 2.24–3.38 was statistically significant for RASTA group (p=0.035. Male gender (mean difference −0.37 log10 copies/10°6 PBMC, p=0.023 and previous PI based-ART (mean difference +0.39 log10 copies/10°6 PBMC, p=0.036 were predictive of HIV DNA level at W0. After adjusting for previous PI based-ART, male gender was the only variable independently associated with HIV DNA size at W0 (mean difference −0.326 log10 copies/10°6 PBMC, 95% CI −0.641, −0.011 p=0.043. Ultrasensitive HIV-1 RNA was detectable at W0 in 50% of RASTA group versus 66.7% of controls and at W48 in 32.4% versus 45.5%, respectively. No differences were found between HIV RNA levels at W0 and W48 within and between the two groups. Conclusions: Switching to

    Full Text Available Introduction: Recent single-site studies and case reports have linked atazanavir (ATV with the occurrence of nephrolithiasis. The purpose of this study was to estimate and compare the incidence rate of nephrolithiasis and to characterize the occurrence of subsequent renal failure among patients on ATV, other protease inhibitors (PIs and PI-free regimens using real world data. Materials and Methods: This was a retrospective cohort analysis using claims data from a US commercial and a US public health insurance database (Medicaid spanning 2003–2011 and 2006–2011, respectively. We identified adult HIV patients who were prescribed ATV, other PIs or PI-free regimens with at least 6 months of continuous enrolment prior to the index claim. Nephrolithiasis was defined as an inpatient or outpatient ICD-9 diagnosis code for nephrolithiasis or an associated condition, plus an imaging/corrective procedure code. Renal failure was also identified using diagnosis codes among patients experiencing nephrolithiasis. Hazard ratios were estimated using propensity score (PS adjusted Cox regression, crude and adjusted for demographics, baseline comorbidities and comedications. Results: A total of 14,477 patients (ATV: 4,150; other PIs: 4,153; PI-free: 6,174 were identified in the commercial database: 83% male and 20% age ≥50 years. In the Medicaid database, 9,104 patients (ATV: 3,460; other PIs: 3,117; PI-free: 2,527 were identified: 53% male and 25% age ≥50 years. There were significant baseline differences in demographics, comorbidities and concomitant medications among the three cohorts. In adjusted analyses, ATV use was not significantly associated with nephrolithiasis when compared to other PIs. When ATV was compared to PI-free regimens, a positive association was observed in the commercial insurance but not the Medicaid database. In both databases, previous history of nephrolithiasis was the strongest predictor of nephrolithiasis in the ATV

    Full Text Available Five isocaloric (3200kcal/kg diets were used in an experiment designed to investigate the effects of dietary crude protein (CP and feeding regimens on broiler performance. Day-old broilers were randomly distributed into four groups using a completely randomized design. Each group was replicated three times with ten broiler chicks per replicate. The experiment lasted for eight weeks. Broilers in group 1 received 23% CP from 0 to 3 weeks, 20% CP from 3 to 6 weeks and 18% CP from 6 to 8 weeks, while broilers in group 2 received 23% CP between 0 and 6 weeks and 18% CP between 6 and 8 weeks. Besides, broilers in group 3 were fed 23% CP from 0 to 4 weeks and 16% CP from 4 to 8 weeks, whereas group 4 was given 18% CP from 0 to weeks. Water was supplied ad libitum for broilers in the different dietary groups. A metabolic trial was carried out on the third week of the experiment using a total collection method. Proximate analyses of diets and faecal samples were performed according to the methods outlined by the Association Of the Official Analytical Chemists. Results at market age showed that broiler performance with respect to feed intake, weight gain, feed to gain ratio and water intake were not significantly influenced by CP regimens (p>0.05. Furthermore, CP regimens did not significantly influence broilers liveability (p>0.05. Protein retention, fat utilization and available fiber were not significantly influenced among treatments (p> 0.05. Economic data showed that cost to benefit ratio of producing broilers was comparable among broilers for all CP regimens used in this trial (p>0.05. It was concluded that a single diet of 18% CP and 3200kcal/kg metabolizable energy would be most suitable and convenient for farmers who are engaged in on-farm feed production for broilers as compared with the standard feeding regimens of broiler starter and broiler finisher diets.

    Twenty human immunodeficiency virus-infected patients experiencing virologic failure of an indinavir- or ritonavir-containing treatment regimen were evaluated in a prospective, open-label study. Subjects received nelfinavir, saquinavir, abacavir, and either another nucleoside analog (n=10) or nevirapine (n=10). Patients treated with the nevirapine-containing regimen experienced significantly greater virologic suppression at week 24 than those not treated with nevirapine (P=.04). Baseline phenotypic drug susceptibility was strongly correlated with outcome in both treatment arms. Subjects with baseline virus phenotypically sensitive to 2 or 3 drugs in the salvage regimen experienced significantly greater virus load suppression than those with baseline virus sensitive to 0 or 1 drug (median week-24 change=-2.24 log and -0.35 log, respectively; P=.01). In conclusion, non-nucleoside reverse transcriptase inhibitors may represent a potent drug in salvage therapy regimens after failure of an indinavir or ritonavir regimen. Phenotypic resistance testing may provide a useful tool for selecting more effective salvage regimens. PMID:10228057

    Full Text Available Purpose of the study: Guidelines are based on clinical trial data as well as expert opinion and do not reflect economic considerations. Cost-efficacy analysis of recommended regimens allows for a ranking which takes into account both clinical and economic considerations. The aim of the present analysis was thus complement the information provided by the EACS (v6 guidelines regarding recommended initial treatment for HIV-1 infection. Methods: The methodology used was that described in Blasco et al. 2011 [1], but applied to Portugal in terms of (i resource prices, (ii resource utilization upon ART initiation, regimen switch and treatment of adverse events, and (iii subsequent regimen selection according to the initial regimen and the reason for switch. Regarding costs, the payer (National Healthcare Service perspective was considered taking into account only differential direct costs. The time horizon was 48 weeks. Summary of results: In this analysis, efficacy ranged from 66% with ABC/3TC+LPV/r to 86% for TDF/FTC+RAL. TDF/FTC+NVP was the least expensive regimen both in terms of the 48 weeks’ cost of the initial regimen and in terms of the total 48 weeks’ costs (i.e., including sequential therapy and other direct medical costs (7,592#x20AC;. Nonetheless, once cost and efficacy are considered simultaneously, TDF/FTC+NVP ranks third (11,419#x20AC;, ABC/3TC+EFV ranks second (11,073#x20AC; and TDF/FTC+EFV (also available, in a single tablet regimen ranks first (10,888#x20AC; indicating that this is the regimen yielding the lowest cost per suppressed patient. Among regimens containing boosted protease inhibitors, TDF/FTC+DRV/r was the regimen with the lowest cost/efficacy ratio (13,020#x20AC; and TDF/FTC+ATV/r had the highest ratio (15,102#x20AC;. Conclusions: Viral suppression is a relevant efficacy outcome not only due to individual benefits but also from a public health perspective. In this analysis, TDF/FTC+EFV was the initial ART regimen with

    Immunosuppression management in kidney transplantation has evolved to include an increasingly diverse choice of medications. Although informed by patient and donor characteristics, choice of immunosuppression regimen varies widely across transplant programs. Using a novel database integrating national transplant registry and pharmacy fill records, immunosuppression use at 6-12 and 12-24 mo after transplant was evaluated for 22 453 patients transplanted in 249 U.S. programs in 2005-2010. Use of triple immunosuppression comprising tacrolimus, mycophenolic acid or azathioprine, and steroids varied widely (0-100% of patients per program), as did use of steroid-sparing regimens (0-77%), sirolimus-based regimens (0-100%) and cyclosporine-based regimens (0-78%). Use of triple therapy was more common in highly sensitized patients, women and recipients with dialysis duration >5 years. Sirolimus use appeared to diminish over the study period. Patient and donor characteristics explained only a limited amount of the observed variation in regimen use, whereas center choice explained 30-46% of the use of non-triple-therapy immunosuppression. The majority of patients who received triple-therapy (79%), cyclosporine-based (87.6%) and sirolimus-based (84.3%) regimens continued them in the second year after transplant. This population-based study of immunosuppression practice demonstrates substantial variation in center practice beyond that explained by differences in patient and donor characteristics.

    Retention wires permanently bonded to the anterior teeth are used after orthodontic treatment to prevent the teeth from relapsing to pre-treatment positions. A disadvantage of bonded retainers is biofilm accumulation on the wires, which produces a higher incidence of gingival recession, increased pocket depth and bleeding on probing. This study compares in vivo biofilm formation on single-strand and multi-strand retention wires with different oral health-care regimens. Two-centimetre wires were placed in brackets that were bonded to the buccal side of the first molars and second premolars in the upper arches of 22 volunteers. Volunteers used a selected toothpaste with or without the additional use of a mouthrinse containing essential oils. Brushing was performed manually. Regimens were maintained for 1 week, after which the wires were removed and the oral biofilm was collected to quantify the number of organisms and their viability, determine the microbial composition and visualize the bacteria by electron microscopy. A 6-week washout period was employed between regimens. Biofilm formation was reduced on single-strand wires compared with multi-strand wires;bacteria were observed to adhere between the strands. The use of antibacterial toothpastes marginally reduced the amount of biofilm on both wire types, but significantly reduced the viability of the biofilm organisms. Additional use of the mouthrinse did not result in significant changes in biofilm amount or viability. However, major shifts in biofilm composition were induced by combining a stannous fluoride-or triclosan-containing toothpaste with the mouthrinse. These shifts can be tentatively attributed to small changes in bacterial cell surface hydrophobicity after the adsorption of the toothpaste components, which stimulate bacterial adhesion to the hydrophobic oil, as illustrated for a Streptococcus mutans strain.

  15. Central nervous system HIV infection in "less-drug regimen" antiretroviral therapy simplification strategies.

    2014-02-01

    Less-drug regimens (LDR) refer to combinations of either two antiretroviral drugs or ritonavir-boosted protease inhibitor (PI) monotherapy. They may represent a simplification strategy in patients with persistently suppressed human immunodeficiency virus (HIV) viremia, with the main benefits of reducing drug-related toxicities and costs. Systemic virological efficacy of LDR is slightly lower as compared with combined antiretroviral therapy (cART), but patients with failure do not usually develop drug resistance and resuppress HIV replication after reintensification. A major concern of LDR is the lower efficacy in the virus reservoirs, especially in the central nervous system (CNS), where viral compartmentalization and independent evolution of infection may lead to CNS viral escape, often associated with neurologic symptoms. The authors reviewed studies of virological and functional CNS efficacy of LDR, particularly of boosted PI monotherapy regimens, for which more information is available. Symptomatic viral CSF escape was observed mainly in PI/r monotherapy patients with plasma failure and low nadir CD4+ cell counts, and resolved upon reintroduction of triple drug cART, whereas asymptomatic viral failure in CSF was not significantly more frequent in patients on PI/r monotherapy compared with patients on standard cART. In addition, there was no difference in functional outcomes between PI monotherapy and cART patients, irrespective of CSF viral escape. More data are needed on the CNS effect of dual ART regimens and, in general, on long-term efficacy of LDR. Simplification with LDR may be an attractive option in patients with suppressed viral load, if they are well selected and monitored for potential CNS complications.

    Glucocorticoids (GC) are widely used to treat systemic sclerosis (SSc). The lack of efficacy data and patient/physician concerns may prompt therapy discontinuation. The aim of this study is to identify factors hampering GC discontinuation in patients with stable disease on oral GC for longer than 12 months. Consecutive patients fulfilling the 2013 ACR/EULAR criteria for SSc and with stable disease were prescribed a slow tapering GC regimen to achieve discontinuation. At study entry and 6 months later (T6), patients were assessed for disease activity and severity. Moreover, the Short-Form-36; the Health Assessment Questionnaire Disability Index (HAQ-DI); and visual analog scales for fatigue, pain, and general health were completed. Reasons for stopping the discontinuation regimen were recorded. Forty-eight patients (46 females, 9 diffuse SSc), with a mean ± SD age of 56±14 years and a median disease duration of 10 years (range 2-22), were enrolled. The median daily GC dose was 5 mg (range 5-10; all patients treated with prednisone). At T6, 33 (68.7 %) patients had discontinued GC. The remaining 15 patients could not discontinue GC because of arthralgia in eight, arthritis in two, puffy fingers in two, increased creatine-kinase in two, and bursitis in one patient. At multiple logistic analysis, a higher baseline HAQ-DI was the only independent factor associated with GC need (OR 2.98, 95 % CI 1.20-7.41; p = 0.01). About one third of SSc patients did not achieve a GC-free regimen. Disability as assessed by HAQ-DI was the leading factor hindering GC discontinuation. A low HAQ-DI score can identify candidates for GC discontinuation. PMID:27184047

    The aim of the current study was to assess the acid demineralization susceptibility of bleached dental enamel submitted to different fluoride regimens. One hundred bovine enamel blocks (6×6×3 mm) were randomly divided into 10 groups (n=10). Groups 1 and 2 received no bleaching. Groups 3 to 6 were submitted to an at-home bleaching technique using 6% hydrogen peroxide (HP; G3 and G4) or 10% carbamide peroxide (CP; G5 and G6). Groups 7 to 10 were submitted to an in-office bleaching technique using 35% HP (G7 and G8) or 35% CP (G9 and G10). During bleaching, a daily fluoridation regimen of 0.05% sodium fluoride (NaF) solution was performed on groups 3, 5, 7, and 9, while weekly fluoridation with a 2% NaF gel was performed on groups 4, 6, 8, and 10. The samples in groups 2 to 10 were pH cycled for 14 consecutive days. The samples from all groups were then assessed by cross-sectional Knoop microhardness at different depths from the outer enamel surface. The average Knoop hardness numbers (KHNs) were compared using one-way analysis of variance and Tukey tests (α=0.05). The comparison between groups 1 and 2 showed that the demineralization method was effective. The comparison among groups 2 to 6 showed the same susceptibility to acid demineralization, regardless of the fluoridation method used. However, the samples from groups 8 and 10 showed more susceptibility to acid demineralization when compared with group 2 (penamel to acid demineralization. However, the use of 35% HP and 35% CP must be associated with a daily fluoridation regimen, otherwise the in-office bleaching makes the bleached enamel more susceptible to acid demineralization.

    Hematopoietic stem cell transplantation (HSCT) is a curative treatment for otherwise incurable diseases. Conditioning regimen is an important part of HSCT and consists of chemotherapy with or without irradiation. Conditioning exerts myelosuppressive, immunosuppressive and antitumor effects, but also contributes to HSCT-related complications including graft-versus-host disease (GVHD). Since almost 50% of the transplanted patients are conditioned with cytostatics without irradiation, we developed and characterized a GVHD mouse model following conditioning with busulphan and cyclophosphamide. Recipient Balb/c female mice were treated with busulphan (20 mg/kg/day for 4 days) and cyclophosphamide (100 mg/kg/day for two days). After one day of rest, recipient mice were transplanted with 2×10(7) bone marrow and 3×10(7) spleen cells from male C57BL/6 (allogeneic group) or female Balb/c (syngeneic/control group) mice. The allogeneic, but not syngeneic transplanted mice developed GVHD. Histopathology of the major internal organs (liver, pancreas, spleen, lungs, heart and kidney) was examined before conditioning start, after conditioning's end and 5, 7 and 21 days after transplantation using hematoxylin-eosin staining. Decreased spleen cellularity and diminished glycogen content in the liver were observed after conditioning regimen. Histopathological changes such as vasculitis, inflammation and apoptotic cell forms in liver, spleen, pancreas, lungs and heart were observed in allogeneic transplanted mice, however, only hypocellular spleen and extramedullar hematopoiesis were detected in syngeneic transplanted animals. No morphological changes were observed in kidney in either HSCT setting. This is the first study describing early histopathological changes after conditioning regimen with busulphan/cyclophosphamide and dynamics of GVHD development in several major internal organs.

  19. A novel approach to pharmacodynamic assessment of antimicrobial agents: new insights to dosing regimen design.

    Full Text Available Pharmacodynamic modeling has been increasingly used as a decision support tool to guide dosing regimen selection, both in the drug development and clinical settings. Killing by antimicrobial agents has been traditionally classified categorically as concentration-dependent (which would favor less fractionating regimens or time-dependent (for which more frequent dosing is preferred. While intuitive and useful to explain empiric data, a more informative approach is necessary to provide a robust assessment of pharmacodynamic profiles in situations other than the extremes of the spectrum (e.g., agents which exhibit partial concentration-dependent killing. A quantitative approach to describe the interaction of an antimicrobial agent and a pathogen is proposed to fill this unmet need. A hypothetic antimicrobial agent with linear pharmacokinetics is used for illustrative purposes. A non-linear functional form (sigmoid Emax of killing consisted of 3 parameters is used. Using different parameter values in conjunction with the relative growth rate of the pathogen and antimicrobial agent concentration ranges, various conventional pharmacodynamic surrogate indices (e.g., AUC/MIC, Cmax/MIC, %T>MIC could be satisfactorily linked to outcomes. In addition, the dosing intensity represented by the average kill rate of a dosing regimen can be derived, which could be used for quantitative comparison. The relevance of our approach is further supported by experimental data from our previous investigations using a variety of gram-negative bacteria and antimicrobial agents (moxifloxacin, levofloxacin, gentamicin, amikacin and meropenem. The pharmacodynamic profiles of a wide range of antimicrobial agents can be assessed by a more flexible computational tool to support dosing selection.

    Tuberculosis is the leading infectious cause of death worldwide, with 9·6 million cases and 1·5 million deaths reported in 2014. WHO estimates 480,000 cases of these were multidrug resistant (MDR). Less than half of patients who entered into treatment for MDR tuberculosis successfully completed that treatment, mainly due to high mortality and loss to follow-up. These in turn illustrate weaknesses in current treatment regimens and national tuberculosis programmes, coupled with operational treatment challenges. In this Review we provide an update on recent developments in the tuberculosis drug-development pipeline (including new and repurposed antimicrobials and host-directed drugs) as they are applied to new regimens to shorten and improve outcomes of tuberculosis treatment. Several new or repurposed antimicrobial drugs are in advanced trial stages for MDR tuberculosis, and two new antimicrobial drug candidates are in early-stage trials. Several trials to reduce the duration of therapy in MDR and drug-susceptible tuberculosis are ongoing. A wide range of candidate host-directed therapies are being developed to accelerate eradication of infection, prevent new drug resistance, and prevent permanent lung injury. As these drugs have been approved for other clinical indications, they are now ready for repurposing for tuberculosis in phase 2 clinical trials. We assess risks associated with evaluation of new treatment regimens, and highlight opportunities to advance tuberculosis research generally through regulatory innovation in MDR tuberculosis. Progress in tuberculosis-specific biomarkers (including culture conversion, PET and CT imaging, and gene expression profiles) can support this innovation. Several global initiatives now provide unique opportunities to tackle the tuberculosis epidemic through collaborative partnerships between high-income countries and middle-income and low-income countries for clinical trials training and research, allowing funders to

    Histone deacetylase (HDAC) inhibitors are promising new compounds for the therapy of fibrotic diseases. In this study we compared the effect of two HDAC inhibitors, trichostatin A and valproic acid, in an experimental model of kidney fibrosis. In mice, doxorubicin (adriamycin) can cause nephropathy characterized by chronic proteinuria, glomerular damage and interstitial inflammation and fibrosis, as seen in human focal segmental glomerulosclerosis. Two treatment regimens were applied, treatment was either started prior to the doxorubicin insult or delayed until a significant degree of proteinuria and fibrosis was present. Pre-treatment of trichostatin A significantly hampered glomerulosclerosis and tubulointerstitial fibrosis, as did the pre-treatment with valproic acid. In contrast, the development of proteinuria was only completely inhibited in the pre-treated valproic acid group, and not in the pre-treated trichostatin A animals. In the postponed treatment with valproic acid, a complete resolution of established doxorubicin-induced proteinuria was achieved within three days, whereas trichostatin A could not correct proteinuria in such a treatment regimen. However, both postponed regimens have comparable efficacy in maintaining the kidney fibrosis to the level reached at the start of the treatments. Moreover, not only the process of fibrosis, but also renal inflammation was attenuated by both HDAC inhibitors. Our data confirm a role for HDACs in renal fibrogenesis and point towards a therapeutic potential for HDAC inhibitors. The effect on renal disease progression and manifestation can however be different for individual HDAC inhibitors. - Highlights: • Valproic acid is a potent antiproteinuric drug, whereas trichostatin A is not. • Trichostatin A and valproic acid reduce kidney fibrosis in doxorubicin nephropathy. • Both valproic acid and trichostatin A attenuate renal inflammation.

    Full Text Available BACKGROUND: Daily pre-exposure prophylaxis (PrEP with Truvada (a combination of emtricitabine (FTC and tenofovir (TFV disoproxil fumarate (TDF is a novel HIV prevention strategy recently found to prevent HIV transmission in men who have sex with men and heterosexual couples. We previously showed that a coitally-dependent Truvada regimen protected macaques against rectal SHIV transmission. Here we examined FTC and tenofovir TFV exposure in vaginal tissues after oral dosing and assessed if peri-coital Truvada also protects macaques against vaginal SHIV infection. METHODS: The pharmacokinetic profile of emtricitabine (FTC and tenofovir (TFV was evaluated at first dose. FTC and TFV levels were measured in blood plasma, rectal, and vaginal secretions. Intracellular concentrations of FTC-triphosphate (FTC-TP and TFV-diphosphate (TFV-DP were measured in PBMCs, rectal tissues, and vaginal tissues. Efficacy of Truvada in preventing vaginal SHIV infection was assessed using a repeat-exposure vaginal SHIV transmission model consisting of weekly exposures to low doses of SHIV162p3. Six pigtail macaques with normal menstrual cycles received Truvada 24 h before and 2 h after each weekly virus exposure and six received placebo. Infection was monitored by serology and PCR amplification of SHIV RNA and DNA. RESULTS: As in humans, the concentration of FTC was higher than the concentration of TFV in vaginal secretions. Also as in humans, TFV levels in vaginal secretions were lower than in rectal secretions. Intracellular TFV-DP concentrations were also lower in vaginal tissues than in rectal tissues. Despite the low vaginal TFV exposure, all six treated macaques were protected from infection after 18 exposures or 4 full menstrual cycles. In contrast, all 6 control animals were infected. CONCLUSIONS: We modeled a peri-coital regimen with two doses of Truvada and showed that it fully protected macaques from repeated SHIV exposures. Our results open the possibility

    Full Text Available INTRODUCTION: Bortezomib has significantly improved multiple myeloma (MM response rates, but strategies for choosing bortezomib-based regimens for initial MM therapy are not standardized. Here, we describe four bortezomib-based therapies in Chinese MM patients to determine the optimal chemotherapeutic approach. METHODS: Newly diagnosed symptomatic MM patients at three hematological centers between February 1, 2006 and May 31, 2013 were treated with therapies including bortezomib plus dexamethasone (PD or combinations of PD with either adriamycin (PAD, cyclophosphamide (PCD or thalidomide (PTD for every 28 days. RESULTS: The overall response rate of all the 215 eligible patients was 90.2%. The ORR for PCD, PAD, PTD and PD were 97.4%, 93.2%, 85.3% and 77.8% while the effects with VGPR or better were 63.7%, 62.7%, 44.2% and 37.8%, respectively. The effect of ORR, VGPR and CR/nCR for the PCD regimen was better than the PD protocol. Median PFS for all patients was 29.0 months with significant differences observed among treatment groups. Median OS of all the patients was not reached, but three-drug combinations were superior to PD alone. Frequently observed toxicities were neutropenia, thrombocytopenia, fatigue, infection, herpes zoster, and peripheral neuropathy. The incidence of peripheral neuropathy (PN in PTD group was significantly higher than other three groups, especially grade 2-3 PN. Treatment with anti-viral agent acyclovir significantly reduced the incidence of herpes zoster. CONCLUSIONS: Our experience indicated that bortezomib-based regimens were effective and well-tolerated in the Chinese population studied; three-drug combinations PCD, PAD were superior to PD, especially with respect to PCD.

    Full Text Available Background: Induction therapy followed by high-dose chemotherapy and autologous transplantation is the standard treatment for suitable patients with multiple myeloma. Objective: The aim of this study was to assess whether induction therapy with thalidomidecontaining regimens was associated with improved results compared to vincristine, doxorubicin, and dexamethasone, and whether cyclophosphamide, thalidomide, and dexamethasone were associated with better results than thalidomide and dexamethasone. Methods: The records of 152 patients who underwent autologous transplantation at this institution from August of 2004 to January of 2012 were reviewed, selecting those with at least partial response to a maximum of eight cycles of induction therapy and sufficient follow-up information for analysis. Results: This study included 89 patients; 44 were female, with a mean age of 55 years (there was a significant trend for increasing age over the years of the study.The median number of induction therapy cycles was four, again with a trend of increase over the years.At least a very good partial response to induction therapy was achieved more often in the cyclophosphamide, thalidomide, and dexamethasone group (61.1% and in the thalidomide and dexamethasone group (59.2% than in the vincristine, doxorubicin, and dexamethasone group (16.2%. The overall median progression-free survival was 34 months, with no statistically significant difference between the three groups. The overall median survival was not reached, and there was no significant difference between the three groups; the estimated five-year overall survival was 55%. Conclusion: Although the quality of responses appeared to be better with thalidomidecontaining regimens, these improvements did not translate into improved long-term outcomes. Given its track record, cyclophosphamide, thalidomide, and dexamethasone is currently considered the preferred regimen for first-line induction therapy in the

    Full Text Available Objective: To evaluate the treatment outcome of second line drugs used in directly observed treatment, short-course (DOTS-Plus regimen under Revised National Tuberculosis Control Program (RNTCP. Materials and Methods: A prospective, observational study was carried out on multidrug resistant tuberculosis (MDR-TB patients enrolled for DOTS-Plus regimen at TB and Chest Disease Department from January to December 2009. Demographic details, symptoms, sputum examination and adverse drug reactions were recorded in a case record form. Patients were followed up for 24 months. The data were analysed by Fisher′s exact test and paired student′s ′t′ test. Results: Out of 130 patients, 51 (39% were cured, 7 (5% completed the treatment, 25 (19% died, 30 (23% defaulted and 17 (13% failure. A significant increase in body weight (P < 0.0001 was observed at the end of the 24 months. Out of 89 patients with sputum culture conversion, majority (73 turned negative within first 3 months. Female gender (P < 0.05, conversion of sputum culture from positive to negative (P < 0.0001, and radiological improvement (P < 0.0001 were found to be positive predictors of a successful treatment outcome. While smoking habit (P < 0.05 and alcohol consumption (P < 0.05 were negative predictors of successful treatment outcome. Thirty five (26% patients developed ADRs that required withdrawal of causal drug. The most common ADR was joint pain due to pyrazinamide (11 followed by neurological and psychiatric disturbances due to cycloserine (9. Conclusion: The treatment outcome of standardized regimen in MDR-TB patients was low. The long duration of treatment and defaulters are major challenges for a successful outcome.

    The prevailing view is that the popular recreational drug (+/-)3,4-methylenedioxymethamphetamine (MDMA, or ``ecstasy'') is a selective serotonin neurotoxin in animals and possibly in humans. Nonhuman primates exposed to several sequential doses of MDMA, a regimen modeled after one used by humans, developed severe brain dopaminergic neurotoxicity, in addition to less pronounced serotonergic neurotoxicity. MDMA neurotoxicity was associated with increased vulnerability to motor dysfunction secondary to dopamine depletion. These results have implications for mechanisms of MDMA neurotoxicity and suggest that recreational MDMA users may unwittingly be putting themselves at risk, either as young adults or later in life, for developing neuropsychiatric disorders related to brain dopamine and/or serotonin deficiency.

    Early rejection can still complicate renal transplantation even with cyclosporin. We added low-dose allopurinol (25 mg on alternative days) to "triple" immunosuppression with cyclosporin, prednisolone, and azathioprine for twelve recipients of cadaver renal grafts. The controls were fifteen patients on triple therapy alone. Only one rejection episode occurred among the allopurinol-treated patients, whereas eleven controls had rejections (seven with more than one episode). Allopurinol may be toxic when combined with azathioprine, yet the bone marrow tolerated the new regimen well. As expected, reduction of the azathioprine dose was necessary in the treated group.

For each drug, the patient was asked to specify medication-related factors of interest, ie, dosage form, dosage interval, required relationship with food intake, and the planned time of day for intake, and to rate the individual relevance of each prevalent parameter on a three-point Likert scale (discriminating between prefer, neutral, and dislike.Results: Tablets with a once-daily dosage frequency were the most preferred dosage form, with a high prevalence in the ambulatory setting. Drug intake in the morning and evening were most preferred, and drug intake at noon was least preferred, but also had a low prevalence in contrast with drug intake independent of meals that was most preferred. Interestingly, only one quarter (26.4% of all the patients were able to indicate clear preferences or dislikes.Conclusion: When patients are asked to specify their preferences for relevant medication regimen characteristics, they clearly indicated regimens that have been associated with better adherence in earlier studies. Therefore, our results suggest that adaptation of drug regimens to individual preferences might be a promising strategy to improve adherence. Because the German health care system may differ from other systems in relevant aspects, our findings should be confirmed by evaluation of patient

    Nancy C Sambol

    Full Text Available The combination of short-acting dihydroartemisinin and long-acting piperaquine (DP is among the first-line therapies for the treatment of uncomplicated Plasmodium falciparum malaria. Population pharmacokinetic models of piperaquine (PQ based on data from acute treatment of young children can be used to predict exposure profiles of piperaquine under different DP chemoprevention regimens. The purpose of our study was to make such predictions in young children.Based on a prior population pharmacokinetic model of PQ in young Ugandan children, we simulated capillary plasma concentration-time profiles (including their variability of candidate chemoprevention regimens for a reference population of 1-2 year olds weighing at least 11 kg. Candidate regimens that were tested included monthly administration of standard therapeutic doses, bimonthly dosing, and weekly dosing (with and without a loading dose.Once daily doses of 320 mg for three days (960 mg total at the beginning of each month are predicted to achieve an average steady-state trough capillary piperaquine concentration of 35 ng/mL, with 60% achieving a level of 30 ng/mL or higher. In contrast, weekly dosing of 320 mg (i.e., 33% higher amount per month is predicted to approximately double the average steady-state trough concentration, increase the percent of children predicted to achieve 30 ng/mL or higher (94%, while at the same time lowering peak concentrations. Exposure at steady-state, reached at approximately 3 months of multiple dosing, is expected to be approximately 2-fold higher than exposure following initial dosing, due to accumulation. A loading dose improves early exposure, thereby reducing the risk of breakthrough infections at the initiation of chemoprevention.Once weekly chemoprevention of DP predicts favourable exposures with respect to both trough and peak concentrations. These predictions need to be verified, as well as safety evaluated, in field-based clinical studies of young

  14. NOVP: a novel chemotherapeutic regimen with minimal toxicity for treatment of Hodgkin's disease

    International Nuclear Information System (INIS)

    Patients with early-staged Hodgkin's disease have had a higher relapse rate following radiotherapy alone if they have B symptoms, large mediastinal masses, hilar involvement, or stage III disease. From June 1988 to December 1989, 27 previously untreated patients with early-staged Hodgkin's disease with adverse features for disease-free survival received combined-modality therapy. Seventeen patients had stage I or II disease, 10 had stage III, 5 had B symptoms, 13 had large mediastinal masses, and 6 had peripheral masses measuring 10 cm or more in diameter. All patients initially received three cycles of a novel chemotherapeutic regimen combining Novantrone (mitoxantrone, American Cyanamid Company), vincristine, vinblastine, and prednisone (NOVP). Twenty-four patients with clinically staged I or II disease with adverse features or stage III disease did not undergo laparotomy; three patients had favorable stage I or II disease and at laparotomy had stage III disease. Radiotherapy-treatment fields depended on the extent of nodal involvement. Twenty-six patients completed all therapy as planned to complete remission (CR) and one of these has had progression; she is in second CR following additional radiotherapy. With a median follow-up of 12 months, all patients are alive. Tolerance to treatment was excellent with only grade 1 or 2 nausea, alopecia and myalgias, and brief myelosuppression. NOVP is an effective adjuvant chemotherapy regimen for inducing responses, with minimal toxicity, prior to definitive radiotherapy for patients with early-staged Hodgkin's disease

    Objective: To evaluate the efficacy of neoadjuvant chemotherapy and explore a sensitive and objective way in the evaluation of neoadjuvant chemotherapy, the pathological changes and BCSG1 expression were studied by pathological and immunohistochemical method in breast cancer patients with CAF neoadjuvant chemotherapy (Cyclophosphamide, Adriamycin and Fluorouracil, CAF) and those without at the same period. Methods: Specimens were obtained from 34 breast cancer patients receiving neoadjuvant CAF regimen chemotherapy (CAF group) and 110 breast cancer patients not receiving neoadjuvant chemotherapy (control group). The BCSG1 expression was detected by SP immunohistochemistry.Correlation between BCSG1 expression and pathological response to CAF neoadjuvant chemotherapy was analyzed. Results: Overall response rate to neoadjuvant chemotherapy was 79.4%. The strong cytoplasm expression of BCSG1 was significantly lower in CAF group than in control group (29.4% vs. 64.5%,P<0.01). In CAF group, the positive cytoplasm expression in partial response (PR) (grade Ⅱ) cases was significantly lower than that in no response (NR) (grade Ⅲ) cases (P=0.002). Conclusion: Neoadjuvant chemotherapy of CAF regimen could decrease the nuclear expression of BSCG1 in breast cancer.

    Allogeneic stem cell transplantation (SCT) is a potentially curative treatment for patients with hematological malignancies. These diseases, however, have their peak incidence in the sixth to eighth decades of life. Historically, elderly patients have been considered unsuitable candidates for SCT because of high treatment-related mortality (TRM). Over the past 15 years, the use of reduced-intensity conditioning (RIC) regimens before SCT has allowed patients in the sixth and seventh decades of life to be routinely transplanted. Despite major differences among transplant centers in the intensity and composition of the conditioning regimen and immunosuppression, choice of graft source, postgraft immunomodulation, and supportive care, there has been a dramatic decrease in TRM, allowing safer delivery of SCT. Major obstacles to SCT in elderly patients include donor availability, graft-versus-host disease, delayed immune recovery, multiple comorbidities, and chemo refractoriness. Here we review the current results of SCT in elderly patients, focusing on the role of RIC, and using myeloid diseases as the model for discussion.

    Forty-two children, all over one year of age, were given vincristine, cyclophosphamide, and sequentially timed cisplatin and VM-26 (OPEC) or OPEC and doxorubicin (OPEC-D) as initial treatment for newly diagnosed stage III or IV neuroblastoma. Good partial response was achieved in 31 patients (74%) overall and in 28 (78%) of 36 patients whose treatment adhered to the chemotherapy protocol, compared with a 65% response rate achieved in a previous series of children treated with pulsed cyclophosphamide and vincristine with or without doxorubicin. Only six patients, including two of the six children whose treatment did not adhere to protocol, failed to respond, but there were five early deaths from treatment-related complications. Tumor response to OPEC, which was the less toxic of the two regimens, was at least as good as tumor response to OPEC-D. Cisplatin-induced morbidity was clinically significant in only one patient and was avoided in others by careful monitoring of glomerular filtration rate and hearing. Other centers should test the efficacy of OPEC or equivalent regimens in the treatment of advanced neuroblastoma. PMID:6539811

    Aim This study aimed to evaluate the success of H.pylori eradication therapy in patients with dyspepsia by therapeutics regimes with and without clidinium C. Background Helicobacter pylori infections are reported in all parts of the world. Appropriate antibiotic therapy can treat infection. The ideal treatment regimen has not been specified. Patients and methods In a randomized, double blind clinical trials study, 250 patients with dyspepsia were enrolled. All patients were treated by Omeprazole, Metronidazole, Amoxicillin and Bismuth (OMAB) for two weeks. One tablet clidinium C before each meal was added to this regimen in the intervention group (A). Urea Breath Test (UBT) was carried out after 8-12 weeks after treatment for evaluation of H.pylori eradication. Results 132 patients in the intervention group (A) and 118 patients in the control group (B) were enrolled to the study. The rate of eradication in group A was significantly higher than group B (62.1% vs. 50%, p=0.04). Conclusion The results supported the effect of clidinium C for increasing of helicobacter pylori eradication, but further studies need to be performed. PMID:24834261

    Patients with early-staged Hodgkin's disease have had a higher relapse rate following radiotherapy alone if they have B symptoms, large mediastinal masses, hilar involvement, or stage III disease. From June 1988 to December 1989, 27 previously untreated patients with early-staged Hodgkin's disease with adverse features for disease-free survival received combined-modality therapy. Seventeen patients had stage I or II disease, 10 had stage III, 5 had B symptoms, 13 had large mediastinal masses, and 6 had peripheral masses measuring 10 cm or more in diameter. All patients initially received three cycles of a novel chemotherapeutic regimen combining Novantrone (mitoxantrone, American Cyanamid Company), vincristine, vinblastine, and prednisone (NOVP). Twenty-four patients with clinically staged I or II disease with adverse features or stage III disease did not undergo laparotomy; three patients had favorable stage I or II disease and at laparotomy had stage III disease. Radiotherapy-treatment fields depended on the extent of nodal involvement. Twenty-six patients completed all therapy as planned to complete remission (CR) and one of these has had progression; she is in second CR following additional radiotherapy. With a median follow-up of 12 months, all patients are alive. Tolerance to treatment was excellent with only grade 1 or 2 nausea, alopecia and myalgias, and brief myelosuppression. NOVP is an effective adjuvant chemotherapy regimen for inducing responses, with minimal toxicity, prior to definitive radiotherapy for patients with early-staged Hodgkin's disease.

    Objective The purpose of this study was to investigate compliance of long-term xylitol and sorbitol chewing gum regimens in adult women participating in a double-blind randomized controlled clinical trial. Design The participants included 122 mothers (age range: 16–35 years) residing in the city of Bauru, São Paulo, Brazil. Compliance with the xylitol and sorbitol chewing gum regimens was assessed by weighing, with a precision balance, all used gums returned in zip-lock bags during the study period of 33 months. The total number of returned bags in both chewing gum groups was computed and the differences between groups were determined by one-way ANOVA. Compliance was further categorized into excellent, good, fair or poor based on the distribution of the combined data for both groups by quartiles. These distributions for the xylitol and sorbitol groups were subjected to chi-square analysis. Results Compliance was always superior for the xylitol group in all categories. These distributions were, however, not significantly different in statistical terms. Average compliance in the xylitol chewing gum group was significantly higher when compared to the sorbitol chewing gum group (p=0.0481). Conclusions The results suggest that compliance, and possibly acceptance in this population, was superior for xylitol chewing gum than for sorbitol chewing gum. PMID:22241940

    Promoting adherence to treatment among pediatric and adult patients with inflammatory bowel disease (IBD) is a critical yet challenging task for health care providers. Several existing interventions to enhance adherence among individuals with IBD offer useful information about practical strategies to enhance adherence. The current review article has 3 goals. First, the review provides a context for understanding treatment regimen adherence in IBD by reviewing key definitional, measurement, and conceptual challenges in this area. Next, published studies focused on interventions to enhance adherence in IBD are briefly summarized, followed by a synthesis of practical adherence promotion strategies for use in IBD by health care providers. Strategies are distinguished by the level of evidence supporting their utility as well as by age group. Finally, recommendations for future research to facilitate the development and implementation of practical, evidence-based strategies for adherence promotion in IBD are provided. Findings from the literature review suggest that strategies including education, regimen simplification, and use of reminder systems and organizational strategies (e.g., pill boxes) are likely to be best suited for addressing accidental nonadherence. In contrast, addressing motivational issues, teaching problem-solving skills, and addressing problematic patterns of family functioning are more likely to benefit individuals displaying intentional nonadherence.

    Full Text Available Single tablet regimens (STRs for HIV infection improve patient satisfaction, quality of life, medication adherence, and virological suppression compared to multitablet regimens (MTRs. This is the first study assessing STR uptake and durability in Australia. This retrospective audit of all patients receiving an STR (n=299 at a large Sydney HIV clinic (January 2012–December 2013 assessed patient demographics, treatment prior to STR, HIV RNA load and CD4 during MTR and STR dosing, and reasons for STR switch. 206 patients switched from previous antiretroviral treatment to an STR, of which 88% switched from an MTR. Reasons for switching included desire to simplify treatment (57%, reduced side effects or toxicity (18%, and cost-saving for the patient. There was no switching for virological failure. Compared to when on an MTR, patients switching to an STR had significantly lower HIV RNA counts (p<0.001 and significantly higher CD4 counts (p<0.001. The discontinuation rate from STR was very low and all patients who switched to an STR maintained virological suppression throughout the study duration, although the study is limited by the absence of a control group.

    Full Text Available Over the past 30 years, there has been no significant improvement in treatment outcomes for patients with advanced stage IV metastatic melanoma, and prognosis remains poor. Melanoma is known to be responsive to immunomodulatory agents, to be a highly vascular tumor, and to be fairly resistant to standard cytotoxic chemotherapy. Ongoing research is attempting to find novel combinations that may have therapeutic synergy. Alternative dosedense schedules of temozolomide appear promising and are being actively investigated, based on their potential to overcome chemoresistance to alkylating agents and the proven activity of temozolomide in the brain. Outcomes of studies investigating single-agent temozolomide suggest that it has activity similar to single-agent dacarbazine. Other studies combining temozolomide with either interferon- alfa or thalidomide suggest that the addition of these immunomodulatory agents to temozolomide improves response rates and may improve overall survival. The best results have been achieved with the extended, daily, dosedense temozolomide regimen. Further research is needed to determine the optimal temozolomide regimen and best combination approach

    2010-02-01

    Full Text Available Currently, there are more than 30 million people infected with HIV-1 and thousands more are infected each day. Vaccination is the single most effective mechanism for prevention of viral disease, and after more than 25 years of research, one vaccine has shown somewhat encouraging results in an advanced clinical efficacy trial. A modified intent-to-treat analysis of trial results showed that infection was approximately 30% lower in the vaccine group compared to the placebo group. The vaccine was administered using a heterologous prime-boost regimen in which both target antigens and delivery vehicles were changed during the course of inoculations. Here we examine the complexity of heterologous prime-boost immunizations. We show that the use of different delivery vehicles in prime and boost inoculations can help to avert the inhibitory effects caused by vector-specific immune responses. We also show that the introduction of new antigens into boost inoculations can be advantageous, demonstrating that the effect of ‘original antigenic sin’ is not absolute. Pre-clinical and clinical studies are reviewed, including our own work with a three-vector vaccination regimen using recombinant DNA, virus (Sendai virus or vaccinia virus and protein. Promising preliminary results suggest that the heterologous prime-boost strategy may possibly provide a foundation for the future prevention of HIV-1 infections in humans.

    Full Text Available Abstract Prognostic markers, such as NPM1, Flt3-ITD, and cytogenetic abnormalities have made it possible to formulate aggressive treatment plans for unfavorable acute myeloid leukemia (AML. However, the long-term survival of AML with unfavorable factors remains unsatisfactory. The latest data indicate that the standard dose of daunorubicin (DNR at 45 mg/m2 is inferior to high dose 90 mg/m2 for induction therapy. The rates of complete remission and overall survival are significantly better in the high dose induction regimen. New regimens exploring the new liposomal encapsulation of Ara-C and DNR as well as addition of gemtuzumab ozogamicin monoclonal antibody have been studied. New agents, including the nucleoside analogues (clofarabine, sapacitabine, elacytarabine, FLT3 inhibitor (sorafenib, farnesyl-transferase inhibitor (tipifarnib, histone deacetylase inhibitor (vorinostat, lenalidomide, as well as DNA methyltransferase inhibitors (decitabine, azacitidine, were recently reported for AML treatment in the 2009 ASH annual meeting. This review also summarizes the updates of the clinical trials on novel agents including voreloxin, AS1413, behenoylara-C, ARRY520, ribavirin, AZD1152, AZD6244, and terameprocol (EM-1421 from the 2009 ASH annual meeting.

    Full Text Available Context Direct acting antivirals (DAAs have recently emerged as a promising therapeutic regimen for the treatment of hepatitis C virus (HCV infection, which is a major public health problem. Among the known DAAs, daclatasvir (DCV, an inhibitor of the non-structural 5A protein, has been used in combination with several drugs for treatment of infection with HCV of different genotypes under different conditions. We conducted a systematic review and meta-analysis of combination therapy with DCV. Evidence Acquisition We performed a systematic search in PubMed, Scopus, Science Direct and Web of Science with appropriate keywords for DCV. Studies that evaluated any regimen containing DCV and reported the sustained virological response (SVR 12 weeks after therapy based on the HCV genotype, treatment duration and use of ribavirin (RBV were included. The selected studies were considered for meta-analysis using STATA 11.0. Results We found six different regimens containing DCV: DCV/asunaprevir (ASV, DCV/ASV/beclubavir, DCV/pegylated interferon lambda or alpha/RBV with or without ASV, DCV/simeprevir, DCV/VX-135 and DCV/sofosbuvir (SOF. Most of these regimens were used for the treatment of HCV genotype 1 infections, and in most cases, treatment failure was noted in subtype 1a infections. Among all these regimens, DCV/SOF with or without RBV for 12 or 24 weeks was found to be an efficacious approach for treatment of different types of patients with infections with different HCV genotypes. Conclusions Among the treatment regimens containing DCV, DCV/SOF has the highest SVR rate for the treatment of infection with different HCV genotypes in different patient contexts; thus, this regimen shows promise for the treatment of HCV infections.

    Onchocerciasis (river blindness), caused by the filarial nematode Onchocerca volvulus, is a major cause of visual impairment and dermatitis in sub-Saharan Africa. As O. volvulus contains an obligatory bacterial symbiont (Wolbachia), it is susceptible to antibiotic chemotherapy, although current regimens are considered too prolonged for community-level control programs. The aim of this study was to compare the efficacies of oxytetracycline and rifampin, administered separately or in combination, against a close relative of O. volvulus (Onchocerca ochengi) in cattle. Six animals per group were treated with continuous or intermittent oxytetracycline regimens, and effects on adult worm viability, dermal microfilarial loads, and Wolbachia density in worm tissues were assessed. Subsequently, the efficacies of 3-week regimens of oxytetracycline and rifampin alone and a combination regimen were compared, and rifampin levels in plasma and skin were quantified. A 6-month regimen of oxytetracycline with monthly dosing was strongly adulticidal, while 3-week and 6-week regimens exhibited weaker adulticidal effects. However, all three regimens achieved >2-log reductions in microfilarial load. In contrast, rifampin monotherapy and oxytetracycline-rifampin duotherapy failed to induce substantive reductions in either adult worm burden or microfilarial load, although a borderline effect on Wolbachia density was observed following duotherapy. Dermal rifampin levels were maintained above the MIC for >24 h after a single intravenous dose. We conclude that oxytetracycline-rifampin duotherapy is less efficacious against O. ochengi than oxytetracycline alone. Further studies will be required to determine whether rifampin reduces oxytetracycline bioavailability in this system, as suggested by human studies using other tetracycline-rifampin combinations.

    Full Text Available Background: If administered properly, dexamethasone cyclophosphamide pulse (DCP therapy has the potential to effect lifelong recovery from pemphigus. Aims: The objective of this paper is to highlight various parameters of DCP therapy and also, to report the effects of a few modifications in the regimen. Methods: An analysis of 123 patients treated with the DCP/DP regimen over a period of five years (1998 to 2002 is presented here. Seventeen patients who did not start/continue the treatment and three patients who died during the treatment have been excluded from the analysis. Twenty patients who had not yet started families were given only dexamethasone pulses (DPs while 103 patients received DCPs. Low dose (50 mg/day cyclophosphamide was used as in the standard regimen. The three modifications introduced into the regimen were: (1 an additional daily dose of oral betamethasone sufficient to control the disease activity during phase I, which was progressively tapered off completely as the patient recovered, (2 use of systemic antibiotics if the patient had skin lesions, and oral anti-candida drugs if the patient had oral ulcers until complete healing, and (3 insistence on thorough cleaning of the skin and scalp with a normal soap and shampoo, and proper maintenance of oral hygiene in spite of skin/mucosal lesions. The regimen consisted of DCP/DP repeated in exactly 28-day cycles, along with 50 mg cyclophosphamide per day, insistence on completing the treatment and avoiding irregular pulses in all patients. The number of DCPs/DPs during phase I varied in different patients depending upon the dose of betamethasone used and the rate of recovery, but phase II (nine DCPs/DPs in exactly 28-day cycles along with 50 mg cyclophosphamide per day and phase III (only 50 mg cyclophosphamide per day was fixed at nine months each. This was followed by posttreatment follow-up (phase IV. Results: At present, all the patients are in complete remission. The

    Full Text Available Objective: To analyze self-reported adherence to antiretroviral regimens containing ritonavir-boosted protease inhibitors, non-nucleoside reverse transcriptase inhibitors (NNRTI, raltegravir, and maraviroc. Methods: Overall, 372 consecutive subjects attending a reference center for HIV treatment in Florence, Italy, were enrolled in the study, from December 2010 to January 2012 (mean age 48 years. A self-report questionnaire was filled in. Patients were defined as “non-adherent” if reporting one of the following criteria:<90% of pills taken in the last month, ≥1 missed dose in the last week, spontaneous treatment interruptions reported, or refill problems in the last 3 months. Gender, age, CD4, HIV-RNA, years of therapy, and type of antiretroviral regimen were analyzed with respect to adherence. Results: At the time of the questionnaire, 89.8% of patients had <50 copies/mL HIV-RNA and 14.2% were on their first combined antiretroviral therapy. 57% of patients were prescribed a regimen containing ritonavir boosted protease inhibitors (boosted PI, 41.7% NNRTI, 17.2% raltegravir, and 4.8% maraviroc; 49.5% of the subjects were on bis-in-die regimens, while 50.5% were on once-daily regimens, with 23.1% of these on the single tablet regimen (STR: tenofovir/emtricitabine/efavirenz. The non-adherence proportion was lower in NNRTI than in boosted-PI treatments (19.4% vs 30.2%, and even lower in STR patients (17.4%. In multivariable logistic regression, patients with the NNRTI regimen (OR: 0.56, 95% CI: 0.34–0.94 and the STR (OR: 0.45, 95% CI: 0.22–0.92 reported lower non-adherence. Efavirenz regimens were also associated with lower non-adherence (OR: 0.42, 95% CI: 0.21–0.83, while atazanavir/ritonavir regimens were associated with higher non-adherence. No other relation to specific antiretroviral drugs was found. A higher CD4 count, lower HIV-RNA, and older age were also found to be associated with lower non-adherence, while a longer time on

    Full Text Available Background: Low adherence to the treatment regimen in tuberculosis patients has been recognized as a major threat for tuberculosis (TB control program. Thus, the present study was conducted to assess the factors affecting adherence to the treatment regimen of TB patients via Health Belief Model (HBM. Methods: In this cross-sectional study,110 tuberculosis patients attending anti-TB center in Zabol were selected and included in the study using census method. Data were collected using Health Belief Model (HBM questionnaire and reviewing the patients' medical files. The collected data were analyzed by SPSS software using t-test, ANOVA and multiple regression analysis with 95 % confidence level. Results: The mean age of the participants was 55.7±18.6 years. 89% of the patients had pulmonary tuberculosis and 11% had extra-pulmonary tuberculosis. The multiple regression analysis showed knowledge, self-efficacy, perceived benefits and perceived threat were significant predictors of adherence to the treatment regimen. The HBM constructs accounted for 29% of the variance observed in adherence to the treatment regimen. Conclusion: The findings of the study highlight the need to increase awareness and change the patients’ beliefs about the risks of low adherence to the treatment regimen in patients.

    Helicobacter pylori infection is a prevalent disease among Iranian children. The purpose of this study was to compare the effect of ciprofloxacin and furazolidone on eradicating helicobacter pylori in Iranian children in combination with amoxicillin and omeprazole. In this cohort study, helicobacter pylori infection was confirmed by gastroscopy, rapid urease test or pathologic assessments. A total of 66 children were randomly enrolled; based on the random number table, and were divided into two groups; first, a combination regimen consisting of ciprofloxacin, amoxicillin, and omeprazole; second, a three-medication regimen consisting of amoxicillin, furazolidone, and omeprazole. The effect of both medical regimens on the successful eradication of helicobacter pylori infection was assessed and compared. Chi-square test was used for evaluating the association between quantitative variables. All comparisons were made at the significance of Peradication of the helicobacter pylori infection was reported 87.9% (29/33) in the first group (CAO) and 60.6% (20.33) in the second group (FAO) (P=0.011). It appears that a major advantage of our proposed regimen over others is a lack of wide use of fluoroquinolones for treating children's diseases. Given FDA's recommendation about the possibility of prescribing ciprofloxacin for infected patients with multidrug resistance, we can use the regimen proposed in this study in patients with resistance to standard treatments.

    2011-01-01

    Full Text Available Background: Oral isotretinoin is recommended for severe nodulocystic acne in the doses of 1-2 mg/kg/day which is usually associated with higher incidence of adverse effects. To reduce the incidence of side-effects and to make it more cost-effective, the lower dose regimen of isotretinoin has been used. Aim: To compare the efficacy and tolerability of oral isotretinoin in daily, alternate, pulse and low-dose regimens in acne of all types and also to assess whether it can be used for mild and moderate acne also. Methods: One hundred and twenty patients with acne were randomized into four different treatment regimens each consisting of 30 patients. Group A was prescribed isotretinoin 1 mg/kg/day, Group B 1 mg/kg alternate day, Group C 1 mg/kg/day for one week/four weeks and Group D 20 mg every alternate day for 16 weeks. Patients were further followed for eight weeks to see any relapse. Side-effects were also recorded. Results: Though the daily high dose treatment Group A performed better initially at eight weeks, at the end of therapy at 16 weeks results were comparable in Group A , B and D. Patients with severe acne did better in Group A than in Group B, C and D. Patients with mild acne had almost similar results in all the groups while patients with moderate acne did better in Group A, B and D. Frequency and severity of treatment-related side-effects were significantly higher in treatment Group A as compared to Group B, C and D. Conclusion: We conclude that for severe acne either conventional high doses of isotretinoin may be used or we can give conventional high dose for initial eight weeks and later maintain on low doses. Use of isotretinoin should be considered in mild to moderate acne also, in low doses; 20 mg, alternate day seems to be an effective and safe treatment option in such cases.

    Despite the clinical success in the real-world of all oral hepatitis C virus (HCV) therapy with response rates approaching that seen in the clinical trials, access has been limited by many payers with discussion of prioritization of treatment based upon AASLD guidelines. We evaluated patients in the TRIO network who were prescribed sofosbuvir (SOF)-based regimens to determine reasons for not starting treatment. Trio Health is a disease management company that works in partnership with academic medical centres, community physicians and specialty pharmacies in the United States to optimize care for HCV. Data for 3841 patients prescribed a sofosbuvir-containing regimen between December 2013 and September 2014 were obtained through this programme. Of the entire group, 315 (8%) patients did not start the prescribed sofosbuvir-containing therapy. A total of 141 (45%) of the nonstart patients had a commercial plan as their primary insurance, 137 (44%) were primarily covered by Medicaid, 17 (5%) were primarily covered by Medicare, and 20 (6%) were either without coverage or coverage was not specified. Reasons for nonstarts were varied and overlapping. Only 15 patients (5% of nonstarts) did not start because they were unreachable or failed to complete required testing. Another 39 patients who did not start (12%) were following their physicians' direction to either wait for new treatment options or to hold treatment for an unspecified reason. Insurance-related processes and financial reasons accounted for 254 (81%) of the 315 nonstarts. The remaining 7 (2%) patients did not have a specified reason for not starting treatment. Nonstart rates were highest in the Medicaid-covered population at 35%. Medicare and Commercial nonstart rates were 2% and 6%, respectively. In a matched comparison, patients with commercial coverage were 6.5 times as likely to start SOF-based therapy compared to patients with Medicaid. Despite high SVR rates of SOF-based regimens in clinical practice

Outcomes were measured using categorical PDC variable (of adherence, PDC ≥ 85%, versus nonadherence, PDC < 85%, with model fit estimated using receiver operator characteristic analysis.Results: The area under the receiver operator characteristic curve for past behavior (Az = 0.78 was significantly greater (P < 0.05 than for patient health beliefs (Az = 0.69, indicating that past prescription-refill behavior is a better predictor of medication adherence than prospective health beliefs. Among health beliefs, the factor most related to medication adherence was behavioral intent (odds ratio, 5.12; 95% confidence interval, 1.84 to 15.06. The factor most strongly related to behavioral intent was impact of regimen on daily routine (odds ratio, 3.3; 95% confidence interval, 1.41 to 7.74.Conclusion: Electronic medical records and community health-information networks may make past prescription-refill rates more accessible and assist physicians with managing medication-regimen adherence. Health beliefs, however, may still play an

    Full Text Available Abstract Background Children with type 1 diabetes (DM1 often use three daily (TID injections with intermediate acting insulin at breakfast and bedtime, and rapid acting insulin at breakfast and dinner. Substituting the evening intermediate acting insulin with a long acting insulin analogue (LAIA at dinner in a twice daily (BID injection regimen may be as effective as a TID regimen. The objective of this pilot study was to compare HbA1c in children with DM1 using a BID regimen with a LAIA at dinner (intervention to those using a standard TID regimen (control over 6 months. Methods Randomized controlled trial with main outcome measure being HbA1c at 0, 3 and 6 months. Secondary outcomes were frequency of adverse events (hypoglycemia, diabetic ketoacidosis, weight gain and scores on the Diabetes Quality of Life Measure for Youth (DQOLY. Results 18 subjects (10 control, 8 intervention. Mean years (standard deviations for control and intervention respectively were: age at diagnosis of DM1 6.31 (2.91 vs 7.76 (3.22, duration of DM1 5.96 (4.95 vs 3.76 (3.37. No significant differences were seen in the mean HbA1c between control and intervention at 0 months [8.48(0.86 vs 8.57(1.13], 3 months [8.47(0.50 vs 7.99(0.61], or 6 months [8.42(0.63 vs 8.30(0.76]. No significant differences were found between groups for frequency of adverse events or DQOLY. Conclusions In this pilot study, incorporating LAIA in a BID regimen did not cause deterioration in HbA1c or increases in adverse events; suggesting that this may be a viable option for families where a more simplified insulin regimen would be beneficial and compliance may be improved.

  18. Cell kinetics of gastrointestinal tumors after different nutritional regimens. A preliminary report

    International Nuclear Information System (INIS)

    Forty-four cases of different untreated gastrointestinal tumors were studied with regard to cell kinetic activity. As a pilot experiment, the authors also determined the 3H-TdR Labeling Index (LI) in 28 patients in basal conditions and after 15 days of nutritional manipulation with prevalently lipid-based or glucose-based feeding to ascertain whether selective nutritional regimens could affect tumor proliferation. Preliminary results from this study indicate that a kinetic perturbation is induced in tumor cells by nutritional manipulation. Lipid-based feeding seems to produce effects similar to those of chemical or physical anticancer agents, thus suggesting a possible supporting role of nutritional manipulation in cancer treatment strategy

  19. Disturbance Of Sleep-Wake Regimen As Prognosis Criterion Of Gastroesophageal Reflux Disease Exacerbation

    Directory of Open Access Journals (Sweden)

    2009-09-01

    Full Text Available The goal of the present research is to define correlation of disease exacerbation risk within the next month and sleep-wake regimen changes in patients with gastroesophageal reflux disease. 40 patients with remission have been examined three times a week to determine qualitative and quantitative indices of sleep characteristic. During the following month the dynamic examination of the mentioned group of patients has been carried out for the purpose of timely acute condition diagnostics. It has been revealed that disturbances of sleep indices, such as late falling asleep, long-term falling asleep, frequency of awakening and unpleasant dreams become unfavorable risk factors for the development of the next recurrence of gastroesophageal reflux disease during the nearest month, but the remission of this disease is significantly connected with falling asleep duration and awakening time.

    Experiments are described which were designed to assess the degree of adaptation that occurs in rats chronically exposed to the stress of a water-deprivation regimen and to determine if that adaptation represents a normalization of the hypothalamic-pituitary-adrenal axis. There were no significant differences in mean corticosterone concentrations among control nondeprived rats 1, 4, and 8 weeks after the start of the experiment. The water-deprived rats, however, had significantly elevated plasma steroids 1 and 4 weeks after the onset of deprivation as compared to controls, but not after 8 weeks. Thus, there was a significant decrease in mean plasma corticosterone levels during water deprivation from 1 week to 8 weeks.

    The increasing number of heart transplant recipients receiving immunosuppression with mammalian target of rapamycin inhibitors prompted the implementation of a South American Transplant Physicians Group to register these patients in a database. Everolimus (EVL) is a signal proliferation inhibition that reduces graft vascular disease when used de novo. Recently, its administration has expanded to subjects with resistant rejection or with side effects due to other immunosuppressive drugs (calcineurin inhibitors and/or steroids), allowing for better regulation of the immunosuppressive regimen. Herein we have shown the data collected from patients receiving EVL in ten South American Heart Transplant Centers. We have concluded that the administration of EVL is a useful adjunctive therapy that allows the reduction or suspension of other immunosuppressive drugs that caused unwanted side effects, without a loss of immunosuppressive efficacy, with manageable side effects, and constituting a valuable therapeutic option.

    In palliative medicine, constipation is the third most common symptom after pain and anorexia, causing some patients to discontinue opioid therapy. Women experience higher incidence of constipation than men. The prevalence of infrequent bowel movements (<3 times/wk) and adherence to an established bowel regimen among women receiving opioids were studied. Referral to the palliative care team decreased the prevalence of infrequent bowel movements from 72% to 45%, and algorithm adherence increased from 38% to 78%. Education of oncology nurses decreased the prevalence of infrequent bowel movements among patients with cancer from 71% to 60%, and algorithm adherence increased from 0% to 10%. Patients benefit from stool softeners and stimulants when receiving opioids. PMID:25964648

    Background Relapses occur frequently in patients with lupus nephritis.Renal biopsy is the gold standard for assessing renal activity and hence guiding the treatment.Whether repeat renal biopsy is helpful during flares of lupus nephritis remains inconclusive.In the present study,we retrospectively reviewed the patients with lupus nephritis who had more than one renal biopsy with the hope to find the clinical value of repeat biopsy.Methods Patients who had a diagnosis of lupus nephritis and two or more renal biopsies were selected from the database of the patient pathology registration at this renal division.Renal biopsy was evaluated according to the International Society of Nephrology/Renal Pathology Society (ISN/RPS) classification of lupus nephritis.The pathological patterns and treatment regimens were analyzed after a repeat biopsy.Results We identified 44 systemic lupus erythematosus patients with serial renal biopsies.In total,there were 94 renal biopsies.Overall,the pathological transition occurred in 64% instances according to the ISN/RPS class.When the transition was analyzed according to proliferative,membranous or mix lesions,it showed different profile:35% in patients with proliferative lesion,23.5% patients with mix lesions,100% in patients with pure membranous lesion.The pathological transition could not be predicted by any clinical characteristics.After the repeat renal biopsy,34% of patients had a change in their treatment regimens.Conclusions The pathological conversion was very prevalent in patients with lupus nephritis.However,the transitions became less prevalent when they were analyzed according to pure membranous,proliferative,and mix lesion.Repeat biopsy might be helpful to avoid unnecessary increased immunosuppression therapy.

    Full Text Available Aims: To study the toxicity of ABVE-PC (doxorubicin, bleomycin, vincristine, etoposide, prednisone and cyclophosphamide and modified-BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide,vincristine, procarbazine, prednisone in intermediate-risk and high-risk Hodgkin lymphoma patients. Methods: High-risk patients received 4 cycles of modified-BEACOPP (m-BEACOPP plus 4 cycles of ABVD. Intermediate-risk patients received 4 cycles of ABVE-PC plus 2 cycles of ABVD. Results: From 2010 to 2014, 17 patients received 66 cycles of m-BEACOPP and 9 patients received 40 cycles of ABVE-PC. In the m-BEACOPP and ABVE-PC courses, respectively, significant thrombocytopenia (<50,000/mm3 occurred in 10.6% vs 0% of courses; anemia (Hb. <8 gm/dl in 27.3% vs 15%; neutropenia (ANC<500/mm3 in 46.9% vs 32.5%; and febrile neutropenia in 33.3% vs. 22.5%. Only episode of documented infection (hepatic abscess occurred in ABVE-PC. There were no episodes of sepsis, typhlitis or pneumonia in either group. All 26 patients are in remission with a median follow-up of 35 months (range, 17-61; and there have been no relapses. Two of 26 (7.7% patients failed to achieve rapid early response after 2 cycles and complete remission after 4 cycles of chemotherapy; both achieved remission with more intensive regimens followed by radiation. The remaining 24 patients did not receive radiation therapy. Conclusions: Both m-BEACOPP and ABVE-PC regimens have acceptable toxicity; and thus can be used in most centres with optimum supportive care facilities. They offer promising response rate and relapse free survival without the need for radiation therapy in most patients; and thus may be considered for children with high-risk and intermediate-risk Hodgkin lymphoma.

    The aim of this cross-over study was to compare clindamycin pharmacokinetics in the serum of clinically normal dogs when administered orally at two dosage regimens (5.5 mg/kg, twice daily, and 11 mg/kg, once daily), separated by a 1 week wash-out period. Serum samples were obtained from six clinically normal laboratory beagles before, 3, 6, 9 and 12 h after the first and fifth dose of clindamycin at 5.5 mg/kg, twice daily, and before, 3, 6, 9, 12, 18 and 24 h after the first and third dose at 11 mg/kg, once daily. Serum clindamycin concentrations were determined by reverse-phase liquid chromatography coupled with mass spectrometry. Results were analysed using Student's paired t-test, at a 5% level of significance. Values of pharmacokinetic parameters that differed significantly between the two dosage regimens included the following: maximal concentration and area under the concentration-time curve were higher at 11 mg/kg, once daily, than at 5.5 mg/kg, twice daily; and, more importantly, the ratio of AUC(0-24) to the minimal inhibitory concentration (MIC) value of 0.5 μg/mL for a 24 h period (AUC(0-24)/MIC) was higher when clindamycin was administered at 11 than at 5.5 mg/kg, at least during the first day of drug administration. Therefore, a better pharmacokinetic profile may be expected when clindamycin is administered at 11 mg/kg, once daily, for the treatment of canine pyoderma caused by Staphylococcus pseudintermedius.

    Crossbred beef x dairy calves were randomly allocated at 3 wk of age to different gonadotropin treatment regimens for stimulation of follicle development and induction of oocyte maturation in vivo. Follicular responses were assessed laparoscopically, and oocytes were aspirated for assessment of maturational state or for in vitro fertilization (IVF) and culture to determine developmental capacity. Follicle-stimulating Hormone (FSH), administered in a single subcutaneous injection together with a low dosage of PMSG, was as effective as the same total dosage of FSH administered in 6 injections over a 3-d period. Without accompanying PMSG, this dose of FSH was ineffective in stimulating follicle development. The mean number of preovulatory follicles (> 5mm, with hyperemic appearance) doubled with each successive stimulation at 3-wk intervals, reaching 35 follicles per calf at 9 wk of age. Oocyte yields ranged from 55 to 81% of follicles aspirated, and did not differ significantly among age, FSH regimen and oocyte maturation stimulus. A combination of LH + FSH was more effective in stimulating cumulus cell expansion than LH by itself (73 vs 22% of recovered oocyte-cumulus cell complex (OCC) respectively; Poocytes (cumulus unexpanded) subjected to in vitro maturation (IVM) and IVF, 30% developed to blastocysts during co-culture with bovine oviduct epithelial cells, which was not significantly different from 25% of 36 oocytes from adult ovaries which reached the blastocyst stage under similar conditions. The results indicate that follicle responses of calf ovaries to FSH stimulation increase progressively from 3 to 9 wk of age, and that oocytes recovered laparoscopically from these follicles produce blastocysts in culture at rates similar to oocytes from adult cattle ovaries collected at slaughter. The approach offers promise for embryo production from donor calves of superior genetic merit for embryo transfer, thereby enhancing the rate of genetic gain above that

    Two CYP51 inhibitors, posaconazole and the ravuconazole prodrug E1224, were recently tested in clinical trials for efficacy in indeterminate Chagas disease. The results from these studies show that both drugs cleared parasites from the blood of infected patients at the end of the treatment but that parasitemia rebounded over the following months. In the current study, we sought to identify a dosing regimen of posaconazole that could permanently clear Trypanosoma cruzi from mice with experimental Chagas disease. Infected mice were treated with posaconazole or benznidazole, an established Chagas disease drug, and parasitological cure was defined as an absence of parasitemia recrudescence after immunosuppression. Twenty-day therapy with benznidazole (10 to 100 mg/kg of body weight/day) resulted in a dose-dependent increase in antiparasitic activity, and the 100-mg/kg regimen effected parasitological cure in all treated mice. In contrast, all mice remained infected after a 25-day treatment with posaconazole at all tested doses (10 to 100 mg/kg/day). Further extension of posaconazole therapy to 40 days resulted in only a marginal improvement of treatment outcome. We also observed similar differences in antiparasitic activity between benznidazole and posaconazole in acute T. cruzi heart infections. While benznidazole induced rapid, dose-dependent reductions in heart parasite burdens, the antiparasitic activity of posaconazole plateaued at low doses (3 to 10 mg/kg/day) despite increasing drug exposure in plasma. These observations are in good agreement with the outcomes of recent phase 2 trials with posaconazole and suggest that the efficacy models combined with the pharmacokinetic analysis employed here will be useful in predicting clinical outcomes of new drug candidates.

    Background A prior study showed significant antibioti resistance to quinotone in our poputation.In this study we aimed to evaluate and compare the efficacy of a single versus a combined prophylactic antibiotic regimen before transrectal ultrasound-guided prostate biopsy(TRUGPB).Methods A prospective randomized study was conducted at a university hospital.Patients undergoing TRUGPB were randomized into an amoicillin-clavulanate alone(1mg;one dose before and two doses after biopsy)or an amoxicllin-clavulanate+ciprofloxacin group(250mg;one dose before and two doses after biopsy).Patients were surveyed for infection symptoms by phine on days 3 and 30 after TRUGPB.We defined an infective complication as the iccurrence of symptoms including fever,chills or rigor within 30 days after prostate biopsy,requiring medical treatment or hospitalization,aided by a tertiory-wide etectronic medical record system.Results Between November 2007 and July 2009,367 patients were randomized to either amoxicillin-clavulanate alone or amoxicillin-caavulanate+ciprofloxacin group.The infection rates after TRUGPB were 3.9%in the former group(7 out of 179 patoents)versus 0.53%(1 out of 188 patients)in the latter.Sixty-three percent(5/8)of patients with infective complications needed hospitalization.There was no intensive care unit admission or mortality during the study period.Conclusions Combining prophylactic antibiotics with amoxicllin-clavulanate+soprofloxacin significantly reduced the in cidence of infective complications after TRUGPB.We recommended a combination regimen,especially in centre with high incidence of post-TRUGPB infection.

    Full Text Available Based on the evidence that hyperglycaemia aggravates ischaemic cerebral injury, it has been suggested that blood glucose levels be kept within 200 mg/dL during intracranial neurosurgery. Hypoglycaemia, however, can be a serious problem if glucose-containing solutions are avoided during the first four hours, as suggested in some studies. In order to explore the possibility of administering glucose in moderation so that the blood glucose levels are within acceptable limits, but at the same time the risk of hyoglycaemia is eliminated, we compared two intraoperative fluid regimens. Of the 52 neurosurgical patients studied, 32 patients received alternately 500 ml of 5% dextrose in normal saline and Ringer′s lactate (DNS/RL Group and 18 patients received alternately 500 ml of Ringer′s lactate and normal saline (RL/NS Group. Blood glucose concentrations were determined at the end of each unit of fluid, until the patient received 4 units of fluid. In the DNS/RL group, blood glucose values peaked with the administration of each unit of DNS and tended to return towards the baseline with the subsequent RL, but remained higher than the previous control value. In the RL/NS group, there was a progressive increase in blood glucose values throughout the study period, but the increase was not statistically significant. The blood glucose levels were significantly different between the two groups after each unit of fluid except at the end of the fourth unit. Two patients in the RL/NS group had hypoglycaemia. In conclusion, the DNS/RL regimen maintains blood glucose levels within acceptable limits while avoiding the risk of hyperglycaemia. Withholding glucose completely, lowers blood glucose levels, but carries a risk of hypoglycaemia in some patients.

    Introduction Consensus on the best treatment regimens for patients with isoniazid-resistant TB is limited; global treatment guidelines differ. We undertook a systematic review and meta-analysis using mixed-treatment comparisons methodology to provide an up-to-date summary of randomised controlled trials (RCTs) and relative regimen efficacy. Methods Ovid MEDLINE, the Web of Science and EMBASE were mined using search terms for TB, drug therapy and RCTs. Extracted data were inputted into fixed-effects and random-effects models. ORs for all possible network comparisons and hierarchical rankings for different regimens were obtained. Results 12 604 records were retrieved and 118 remained postextraction, representing 59 studies—27 standalone and 32 with multiple papers. In comparison to a baseline category that included the WHO-recommended regimen for countries with high levels of isoniazid resistance (rifampicin-containing regimens using fewer than three effective drugs at 4 months, in which rifampicin was protected by another effective drug at 6 months, and rifampicin was taken for 6 months), extending the duration of rifampicin and increasing the number of effective drugs at 4 months lowered the odds of unfavourable outcomes (treatment failure or the lack of microbiological cure; relapse post-treatment; death due to TB) in a fixed-effects model (OR 0.31 (95% credible interval 0.12–0.81)). In a random-effects model all estimates crossed the null. Conclusions Our systematic review and network meta-analysis highlight a regimen category that may be more efficacious than the WHO population level recommendation, and identify knowledge gaps where data are sparse.

    Purpose The optimal dosage and frequency of platinum-based chemoradiotherapy (CRT) regimen for treating advanced head and neck squamous cell carcinoma remains unresolved. This study aims to compare the toxicity and efficacy of weekly versus more dose-intensive cisplatin-based CRTs. Methods We reviewed 155 stage III/IV head and neck squamous cell carcinoma patients with no evidence of distant metastasis treated with one of two CRT regimens from 2000 to 2010 at Greater Baltimore Medical Center. Twice-daily radiation was provided as a split course over a 45-day period. Regimen A consisted of concomitant cisplatin (30 mg/m2/1 h) weekly for 6 cycles; regimen B consisted of concomitant cisplatin (12 mg/m2/1 h) and 5-fluorouracil (600 mg/m2/20 h) on days 1 through 5 and days 29 through 33. Main outcome measures included acute toxicities (myelosuppression, neurotoxicity, nephrotoxicity, gastrointestinal dysfunction), unplanned hospitalizations, and disease control at 12 months. Results Patients on regimen A were much less likely to experience ototoxicity due to their treatment (0% vs. 9.8%, P = 0.04). They were more likely to experience thrombocytopenia acutely (46% vs. 26%, P = 0.02), but the toxicity was not limiting (grade 1–2). No significant differences exist in the incidence of other toxicities or unplanned hospitalizations. At 1 year, 97% of patients on A vs. 86% of patients on regimen B were free of disease (P = 0.11). Conclusions With concurrent radiotherapy, low-dose, single-agent, weekly cisplatin is less likely than higher-dose daily cisplatin plus 5-fluorouracil provided at the beginning and end of treatment to be associated with ototoxicity. The preliminary data suggest at least equivalent efficacy, but longer follow-up is required. PMID:22290566

    Full Text Available Background - Colonoscopy is an important diagnostic and therapeutic procedure. Adequate bowel preparation is mandatory. Several regimens were discussed in the literature. Among the drugs which has recently used, polyethylene glycol is one of the most popular agents. Objectives - The aim of this study was to compare efficacy of three different methods for 1 day preparation before colonoscopy. Methods - This study included children with the range of ages (2-21 who had an indication of colonoscopy. Exclusion criteria were based on the history of previous surgery, parental disagreement, and patients who did not use preparation protocol. Three methods for bowel preparation were studied: 1- Polyethylene glycol only; 2- Polyethylene glycol and bisacodyl suppositories; 3- Polyethylene glycol plus normal saline enema. Boston Bowel Preparation Score was used for evaluation of preparation. SPSS version 16.0 (Chicago, IL, USA were used for data analysis. Results - In this study 83 cases completed the bowel preparation completely. Acceptable bowel preparation was seen in 24 (85.71%, 36 (94.73%, and 14 (82.35% of cases in PEG, PEG + bisacodyl, and PEG + normal saline enema groups respectively. PEG + bisacodyl suppositories was more effective than PEG + normal saline for the preparation of the first segment ( P=0.05. For second and third segment of colon, BPPS score was higher in PEG + bisacodyl suppositories compared to other regimens, but this difference was not statistically significant. Conclusion - There was no significant difference between 1 day colonoscopy regimens in terms of bowel preparation score. Lowest score was seen in PEG + enema group compared to other group.

    Full Text Available The different choices of immunosuppression (IS regimens influenced the outcomes of liver transplantation. Steroid was applied as a standard IS to prevent and treat rejections. However, steroid-related complications were increasingly prominent. This study compared the efficacy and safety of standard IS regimens with the efficacy and safety of steroid-free IS regimen and induction IS regimen in Chinese liver transplantation recipients for hepatocellular carcinoma (HCC. A total of 329 patients who underwent liver transplantation from January 2008 to December 2012 were retrospectively reviewed. Three different groups of patients received standard triple-drug IS regimen of steroid, tacrolimus (TAC and mycophenolate mofetil (MMF (triple-drug regimen group; n=57, induction-contained IS regimen of basiliximab, steroid, TAC and MMF (BS group; n=241, and induction-contained and steroid-free regimen of basiliximab, TAC and MMF (SF group; n=31, respectively. There were no significant differences in terms of patient, tumor-free and graft survival rates. The acute rejection rate and rejection time were equivalent in different groups. But compared with BS group, higher incidences of biliary complications (11.52% vs. 30.77%, p=0.013 and graft dysfunction (0.48% vs. 13.64%, p=0.003 were observed in SF group. Furthermore, compared with the two groups, incidence of pleural effusion was also higher in SF group (15.79%, 11.96% vs. 45.45%, respectively, both p<0.01. And a trend towards less proportion of De novo diabetes was revealed in SF group. Although it was found that patient, tumor-free and graft survival rates were equivalent among three IS regimens, higher incidences of complications were demonstrated in steroid-free regimen in patients for HCC. These findings suggested that steroid-free IS regimen has no clear advantages in comparison with standard IS regimens for liver transplant recipients with HCC and the postoperative complications should be treated with

    Conditioning regimens that include cyclophosphamide (CY) and total body irradiation (TBI) induce severe gonadal toxicity and permanent infertility in approximately 90 % of female patients who undergo hematopoietic stem cell transplantation (HSCT). However, the use of ovarian shielding or non-myeloablative regimens may preserve ovarian function. To evaluate the ovarian reserve, serum anti-Müllerian hormone (AMH) levels were retrospectively measured in 11 female HSCT recipients aged less than 40 years, including seven with acute leukemia (AL) and four with aplastic anemia (AA), who received a myeloablative conditioning regimen with ovarian shielding or a reduced-intensity conditioning regimen. In most patients, menstruation had stopped and AMH level had decreased to an undetectable level (<0.1 ng/ml) after HSCT. Most patients showed a recovery of regular menstruation, but AMH levels did not increase immediately after the resumption of menstruation. However, in three AL patients and two AA patients who were evaluable for long-term recovery, AMH level increased gradually beyond 1 year after HSCT. In conclusion, recovery of the serum AMH level may be delayed after HSCT, and the AMH level early after HSCT may not accurately reflect ovarian reserve. A prospective study is required to address the usefulness of measuring the AMH level in HSCT recipients. PMID:27084256

    Previous studies suggest that multiple transplantations might be equally efficient to a single regimen for human adult islets. The aim of this study was to compare metabolic parameters after each of the two regimens of human fetal islet (HFI) transplantation in type 1 diabetics. In group A (single transplant, n = 9), 180 +/- 20 x 1000 HFI equivalents (IEQs) were implanted by a single IM injection; in group B (multiple transplants, n = 8) islets were implanted as three consecutive injections (60 +/- 10 x 1000 IEQs) at 7-day intervals. We analyzed the metabolic parameters on days -1, 30, 60, 90, 120, 150, and 180 after the procedure. Among the metabolic parameters, we evaluated insulin secretion capacity-ISC (C peptide, RIA), metabolic control (HbA1c, chromatography), and insulin daily dose IDD. We found that C peptide levels increased, peaking on day 90 (A: 0.38 +/- 0.15; B: 0.34 +/- 0.19 nmol/L, P = NS) and then rapidly decreasing without differences, the HbA1c levels and IDD decreased in the same manner without differences between the groups. Our results demonstrate that multiple and single islet transplant regimens are equally efficient to temporarily restore a significant ISC with improvement of metabolic and clinical parameters. The results imply that the two regimens have an equal clinical value.

    OBJECTIVE: To estimate the extent of drug resistance accumulation in patients kept on a virologically failing regimen and its determinants in the clinical setting. DESIGN: The study focused on 110 patients of EuroSIDA on an unchanged regimen who had two genotypic tests performed at two time points...... January 2006. Patients were grouped according to the number of active drugs in the failing regimen at t0 (GSS_f-t0). RESULTS: At t0, patients had been on the failing combination antiretroviral therapy (cART) for a median of 11 months (range, 6-50 months). Even patients with extensive resistance...... to the failing regimen were still receiving benefit from treatment. An overall 6-monthly increase of 1.96 (SD, 2.23) International Aids Society-mutations and an average loss of 1.25 (SD, 1.81) active drugs were estimated. In comparison with patients with GSS_f-t0 = 0, the number of active drugs lost was -1...

    Shortening the lengthy treatment duration for tuberculosis patients is a major goal of current drug development efforts. The common marmoset develops human-like disease pathology and offers an attractive model to better understand the basis for relapse and test regimens for effective shorter duration therapy. We treated Mycobacterium tuberculosis-infected marmosets with two drug regimens known to differ in their relapse rates in human clinical trials: the standard four-drug combination of isoniazid, rifampin, pyrazinamide, and ethambutol (HRZE) that has very low relapse rates and the combination of isoniazid and streptomycin that is associated with higher relapse rates. As early as 2 weeks, the more sterilizing regimen significantly reduced the volume of lung disease by computed tomography (P = 0.035) and also significantly reduced uptake of [(18)F]-2-fluoro-2-deoxyglucose by positron emission tomography (P = 0.049). After 6 weeks of therapy, both treatments caused similar reductions in granuloma bacterial load, but the more sterilizing, four-drug regimen caused greater reduction in bacterial load in cavitary lesions (P = 0.009). These findings, combined with the association in humans between cavitary disease and relapse, suggest that the basis for improved sterilizing activity of the four-drug combination is both its faster disease volume resolution and its stronger sterilizing effect on cavitary lesions. Definitive data from relapse experiments are needed to support this observation. PMID:25941223

    The purposes of this study were to explore parents' perceptions of satisfaction with care from primary care pediatric nurse practitioners (PNPs) and to explore the relationships of the four components of parental satisfaction with parents' intent to adhere to recommended health care regimen. The study used a descriptive correlational research design. A convenience sample of 91 participants was recruited from practices in southeastern Pennsylvania. The 28-item, Parents' Perceptions of Satisfaction with Care from Pediatric Nurse Practitioners (PPSC-PNP) tool was developed to measure four components of satisfaction and overall satisfaction of parents with PNP care after the health visit. A 100 mm visual analog (VAS) scale measured parental intent to adhere to the care regimen recommended by the PNP. Parents' perceptions of overall satisfaction with care from PNPs and satisfaction with each of the four components (communication, clinical competence, caring behavior, and decisional control) were high as measured by the PPSC-PNP. Multiple regression analysis revealed that clinical competence had the strongest positive relationship with parental intent to adhere to PNP recommended health regimen and was the only variable to enter the regression equation. The findings of this study have implications for nursing practice. The PPSC-PNP instrument may be used with a variety of pediatric populations and settings as a benchmark for quality care. Clinical competence is important for the role of the PNP. Other variables of parental intent to adhere to the health regimen should be explored in future studies. PMID:27468517

    OBJECTIVE To evaluate the clinical effectivity and toxicity of the regimen FMD (fludarabine, mitoxantrone, dexamethasone)in patients with non-Hodgkin's lymphoma. METHODS Thirty-two patients, twenty-four of whom had indolent B-cell lymphoma,6 peripheral T-cell lymphoma, two diffuse large B-cell lymphoma, received FMD. Treatment comprised: fludarabine 25-30 mg/m2 days 1-3, mitoxantrone 8-10 mg/m2day 1, and dexamethasone 20-30 mg/m2 days 1-5.At the same time, patients received prophylaxis against conditional infection with trimethoprim-sulfamethoxazole, fluconazole, acyclovir and immunoglobulin. RESULTS of the thirty-two patients treated, the complete Response(CR)rate, partial response(PR)rate and overall response (OR)rate were 56.3%,21.9%and 78.2%respectively.The CR and OR rate of 24 patients with indolent B-cell lymphoma were 66.7%and 88.3%respectively.Two of six patients with peripheral T-cell lymphoma were of complete response type and one was of partial response type. One of two patients with diffuse large B-cell lymphoma was partial response. The dominating toxicity was myelotoxicity and immunotoxicity. There was no treatment associated death in all patients treated with FMD. Grade 3-4 neutropenia occurred in 43.8%patients,12.5%patients had infections and 9.3%developed grade 3-4 thrombocytopenia. At a median follow-up of 24(5~54)months, the 2-year overall-survival rate and progression-free survival rate were(87.5±1.4)%and(83.3 ±1.6)%respectively. The 2-year OS and PFS rates of the indolent group were (93.75±6.25)%and(87.5±8.54)%. CONCLUSION FMD regimen was highly effective with low toxicity in the treatment of non-Hodgkin's lymphoma, especially in indolent B-cell lymphoma. It also helps to improve the prognosm even in some aggressive lymphoma, such as peripheral T cell lymphoma.

    Full Text Available BACKGROUND Appropriate antibiotic regimens for prevention of infection in open fractures of the facial region are controversial. Although, many randomised and retrospective studies have been performed to evaluate the effect of antibiotic prophylaxis, unfortunately important information is lacking regarding the type, duration, dosage, route of administration, and the time between injury and definitive treatment. AIM The main aim of this study is to evaluate and compare the efficacy of one day versus five day regimens of postsurgical antibiotics in the management of open facial fractures. SETTING AND DESIGN The participants were randomly divided into Group A (35 and Group B (35 based on the duration of receiving postoperative antibiotics. Group A patients received antibiotics for not more than 24 hours postsurgically whereas Group B patients received antibiotics for 5 days postoperatively. Patients in both groups were followed up at 7th , 14th , and 21 days postsurgery and any patient having signs of infection such as pus discharge and fever were counted as infected. METHODS AND MATERIAL 70 patients with open facial fractures requiring open reduction and internal fixation were enrolled for this study. Written and informed consent was taken from the patients regarding the purpose of this study and also the risks involved. STATISTICAL ANALYSIS Chi-square test was applied for comparing categorical variables and student unpaired t test was used to analyse the duration between injury and surgery (In days. RESULTS Postoperative infection rate in Group A was seen in two patients and in one patient in Group B, which was found to be statistically not significant at 0.5 value. In adverse habits, smoking was found to be significant at 0.01. CONCLUSION Preoperative and intraoperative prophylactic antibiotics have proven to be efficacious in lowering infection rates postoperatively, but there is no added advantage if they are continued for more than 24 hours

    Purpose/Objective(s): To perform a meta-regression on published data and to model the 5-year probability of cataract development after hematopoietic stem cell transplantation (HSCT) with and without total body irradiation (TBI). Methods and Materials: Eligible studies reporting cataract incidence after HSCT with TBI were identified by a PubMed search. Seventeen publications provided complete information on radiation dose schedule, fractionation, dose rate, and actuarial cataract incidence. Chemotherapy-only regimens were included as zero radiation dose regimens. Multivariate meta-regression with a weighted generalized linear model was used to model the 5-year cataract incidence and contributory factors. Results: Data from 1386 patients in 21 series were included for analysis. TBI was administered to a total dose of 0 to 15.75 Gy with single or fractionated schedules with a dose rate of 0.04 to 0.16 Gy/min. Factors significantly associated with 5-year cataract incidence were dose, dose times dose per fraction (D•dpf), pediatric versus adult status, and the absence of an ophthalmologist as an author. Dose rate, graft versus host disease, steroid use, hyperfractionation, and number of fractions were not significant. Five-fold internal cross-validation showed a model validity of 83% ± 8%. Regression diagnostics showed no evidence of lack-of-fit and no patterns in the studentized residuals. The α/β ratio from the linear quadratic model, estimated as the ratio of the coefficients for dose and D•dpf, was 0.76 Gy (95% confidence interval [CI], 0.05-1.55). The odds ratio for pediatric patients was 2.8 (95% CI, 1.7-4.6) relative to adults. Conclusions: Dose, D•dpf, pediatric status, and regimented follow-up care by an ophthalmologist were predictive of 5-year cataract incidence after HSCT. The low α/β ratio indicates the importance of fractionation in reducing cataracts. Dose rate effects have been observed in single institution studies but not in the

    Full Text Available The purpose of the study was to assess the acute effects of the self-selected regimen of rapid body mass loss (RBML on muscle performance and metabolic response to exercise in combat sports athletes. Seventeen male athletes (20.8 ± 1.0 years; mean ± SD reduced their body mass by 5.1 ± 1.1% within 3 days. The RBML was achieved by a gradual reduction of energy and fluid intake and mild sauna procedures. A battery of tests was performed before (Test 1 and immediately after (Test 2 RBML. The test battery included the measurement of the peak torque of knee extensors for three different speeds, assessment of total work (Wtot performed during a 3-min intermittent intensity knee extension exercise and measurements of blood metabolites (ammonia, lactate, glucose and urea. Absolute peak torque was lower in Test 2 compared with Test 1 at angular velocities of 1.57 rad·s-1 (218.6 ± 40.9 vs. 234.4 ± 42.2 N·m; p = 0.013 and 3.14 rad·s-1 (100.3 ± 27.8 vs. 111.7 ± 26.2 N·m; p = 0.008. The peak torque in relation to body mass remained unchanged for any speed. Absolute Wtot was lower in Test 2 compared with Test 1 (6359 ± 2326 vs. 7452 ± 3080 J; p = 0.003 as well as Wtot in relation to body mass (89.1 ± 29.9 vs. 98.6 ± 36.4 J·kg-1; p = 0.034, respectively. As a result of RBML, plasma urea concentration increased from 4.9 to 5.9 mmol·l-1 (p = 0.003. The concentration of ammonia in a post-test sample in Test 2 tended to be higher in comparison with Test 1 (80.9 ± 29.1 vs. 67.6 ± 26.5 mmol·l-1; p = 0.082. The plasma lactate and glucose responses to exercise were similar in Test 1 and Test 2. We conclude that the self-selected regimen of RBML impairs muscle performance in 3-min intermittent intensity exercise and induces an increase in blood urea concentration in experienced male combat sports athletes

    Full Text Available BACKGROUND: Limited antiretroviral treatment regimens in resource-limited settings require long-term sustainability of patients on the few available options. We evaluated the incidence and predictors of combined antiretroviral treatment (cART modifications, in an outpatient cohort of 955 patients who initiated cART between January 2009 and January 2011 in western Kenya. METHODS: cART modification was defined as either first time single drug substitution or switch. Incidence rates were determined by Poisson regression and risk factor analysis assessed using multivariate Cox regression modeling. RESULTS: Over a median follow-up period of 10.7 months, 178 (18.7% patients modified regimens (incidence rate (IR; 18.6 per 100 person years [95% CI: 16.2-21.8]. Toxicity was the most common cited reason (66.3%. In adjusted multivariate Cox piecewise regression model, WHO disease stage III/IV (aHR; 1.82, 95%CI: 1.25-2.66, stavudine (d4T use (aHR; 2.21 95%CI: 1.49-3.30 and increase in age (aHR; 1.02, 95%CI: 1.0-1.04 were associated with increased risk of treatment modification within the first year post-cART. Zidovudine (AZT and tenofovir (TDF use had a reduced risk for modification (aHR; 0.60 95%CI: 0.38-0.96 and aHR; 0.51 95%CI: 0.29-0.91 respectively. Beyond one year of treatment, d4T use (aHR; 2.75, 95% CI: 1.25-6.05, baseline CD4 counts ≤350 cells/mm3 (aHR; 2.45, 95%CI: 1.14-5.26, increase in age (aHR; 1.05 95%CI: 1.02-1.07 and high baseline weight >60kg aHR; 2.69 95% CI: 1.58-4.59 were associated with risk of cART modification. CONCLUSIONS: Early treatment initiation at higher CD4 counts and avoiding d4T use may reduce treatment modification and subsequently improve sustainability of patients on the available limited options.

    Full Text Available Introduction: The costs of combination antiretroviral therapy (cART consisting of separate, particularly generic, components are generally much lower than of a single tablet regimen (STR including the same active ingredients. Our aim was to evaluate whether patients in care in the Netherlands would be willing to take separate component regimens (SCR instead of an STR and to examine whether willingness was associated with particular patient characteristics. Materials and Methods: Data from the HIV Monitoring Foundation of all adult HIV-1-infected patients in care taking cART>6 months were used to randomly select 1000 patients. As part of a questionnaire developed for a study assessing patient experience, patients were asked whether they were willing to take an SCR instead of an STR. Logistic regression was used to examine associations between age, gender, region of origin, mode of HIV transmission, socioeconomic status, duration of cART and answering “yes” to the question versus “maybe” or “no.” Variables with p<0.1 in the univariate analysis were entered in a multivariate model. Results: Of the 300 patients who completed the questionnaire, 49% answered “yes,” 24% “maybe” and 27% “no” to the question whether they would be willing to use a SCR. Reasons for answering “no” included difficulties swallowing pills, convenience of STR (especially when travelling/at work, and concerns about side effects. Respondents who answered “maybe” often indicated that they preferred STRs, emphasized the importance of taking the pills once daily, and pointed out that efficacy/safety of an SCR should not be less. Having to pay for medication was reported as a reason to consider switching to an SCR. In the multivariate analysis, respondents who were born outside the Netherlands were less likely; and those with cART use ≥15 yrs were more likely to answer “yes” (Table 1. Conclusions: Half of the respondents were willing to take SCRs

    Full Text Available Abstract Background After the introduction of novel effective immunosuppressive therapies, kidney transplantation became the treatment of choice for end stage renal disease. While these new therapies lead to better graft survival, they can also cause a variety of complications. Only small series or case reports describe pulmonary pathology in renal allograft recipients on mTOR inhibitor inclusive therapies. The goal of this study was to provide a systematic review of thoracic biopsies in kidney transplant recipients for possible association between a type of immunosuppressive regimen and pulmonary complications. Methods A laboratory database search revealed 28 of 2140 renal allograft recipients (18 males and 10 females, 25 to 77 years old, mean age 53 years who required a biopsy for respiratory symptoms. The histological features were correlated with clinical findings including immunosuppressive medications. Results The incidence of neoplasia on lung biopsy was 0.4% (9 cases, which included 3 squamous cell carcinomas, 2 adenocarcinomas, 1 diffuse large B-cell lymphoma, 1 lymphomatoid granulomatosis, and 2 post transplant B-cell lymphoproliferative disorders. Diffuse parenchymal lung disease was identified in 0.4% (9 cases, and included 5 cases of pulmonary hemorrhage, 3 cases of organizing pneumonia and 1 case of pulmonary alveolar proteinosis. Five (0.2% cases showed histological features indicative of a localized infectious process. Patients on sirolimus had neoplasia less frequently than patients on other immunosuppressive combinations (12.5% vs. 58.3%, p = 0.03. Lung biopsies in 4 of 5 patients with clinically suspected sirolimus toxicity revealed pulmonary hemorrhage as the sole histological finding or in combination with other patterns. Conclusions Our study documents a spectrum of neoplastic and non-neoplastic lesions in renal allograft recipients on current immunosuppressive therapies. Sirolimus inclusive regimens are associated with

    Full Text Available OBJECTIVES: Fixed-dose combination formulations, which simplify the administration of drugs and prevent the development of drug resistance, have been recommended as a standard anti-tuberculosis treatment regimen. However, the composition and dosage recommendations for fixed-dose combination formulations differ from those for separate formulations. Thus, questions about the effectiveness and side effects of combination formulations remain. The aim of this study was to compare the safety and efficacy of these two types of anti-tuberculosis regimens for pulmonary tuberculosis treatment. METHOD: A prospective, randomized controlled study was conducted using the directly observed treatment short-course strategy. Patients were randomly allocated to one of two short-course regimens. One year after completing the treatment, these patients’ outcomes were analyzed. ClinicalTrials.gov: NCT00979290. RESULTS: A total of 161 patients were enrolled, 142 of whom were evaluable for safety assessment. The two regimens had a similar incidence of adverse effects. In the per-protocol population, serum bilirubin concentrations at the peak level, at week 4, and at week 8 were significantly higher for the fixed-dose combination formulation than for the separate formulations. All patients had negative sputum cultures at the end of the treatment, and no relapse occurred after one year of follow-up. CONCLUSIONS: In this randomized study, transient higher serum bilirubin levels were noted for the fixed-dose combination regimen compared with the separate formulations during treatment. However, no significant difference in safety or efficacy was found between the groups when the directly observed treatment short-course strategy was used.

    Full Text Available Nutritional infertility is very common in societies where women fail to eat enough to match their energy expenditure and such females often present as clinical cases of anorexia nervosa. The cellular and molecular mechanisms that link energy balance and central regulation of reproduction are still not well understood. Peripheral hormones such as estradiol, testosterone and leptin, as well as neuropeptides like kisspeptin and neuropeptides Y (NPY play a potential role in regulation of reproduction and energy balance with their primary target converging on the hypothalamic median eminence-arcuate region. The present study was aimed to explore the effects of negative energy state resulting from intermittent fasting dietary restriction (IF-DR regimen on complete hypothalamo-hypophysial-gonadal axis in Wistar strain young female and male rats. Significant changes in body weight, blood glucose, estrous cyclicity and serum estradiol, testosterone and LH level indicated the negative role of IF-DR regimen on reproduction in these young animals. Further, it was elucidated whether serum level of metabolic hormone, leptin plays a mechanistic role in suppressing hypothalamo-hypophysial-gonadal (HPG axis via energy regulators, kisspeptin and NPY in rats on IF-DR regimen. We also studied the effect of IF-DR regimen on structural remodeling of GnRH axon terminals in median eminence region of hypothalamus along with the glial cell marker, GFAP and neuronal plasticity marker, PSA-NCAM using immunostaining, Western blotting and RT-PCR. Together these data suggest that IF-DR regimen negatively influences reproduction in young animals due to its adverse effects on complete hypothalamus-hypophysial-gonadal axis and may explain underlying mechanism(s to understand the clinical basis of nutritional infertility.

    Objectives To summarise the literature evaluating the association between different insulin regimens and the incidence of cardiovascular morbidity and mortality in adults with type 2 diabetes. Design Systematic review. Methods Multiple biomedical databases (The Cochrane Library, PubMed, EMBASE, and International Pharmaceutical Abstracts) were searched from their inception to February 2014. References of included studies were hand searched. Randomised controlled trials (RCTs), cohort studies or case–control studies examining adults (≥18 years) with type 2 diabetes taking any type, dose and/or regimen of insulin were eligible for inclusion in this review. Outcome measures Primary outcomes were cardiovascular morbidity and mortality including fatal and/or non-fatal myocardial infarction, fatal and/or non-fatal stroke, major adverse cardiac events and cardiovascular death. All-cause mortality was assessed as a secondary outcome. Results Of the 3122 studies identified, 2 RCTs and 6 cohort studies were selected. No case–control studies met the inclusion criteria. The studies examined a total of 109 910 patients. Quantitative synthesis of the results from included studies was not possible due to a large amount of clinical heterogeneity. Each study evaluated cardiovascular outcomes across different insulin-exposure contrasts. RCTs did not identify any difference in cardiovascular risks among a fixed versus variable insulin regimen, or a prandial versus basal regimen, albeit clinically important risks and benefits cannot be ruled out due to wide CIs. Findings from cohort studies were variable with an increased and decreased risk of cardiovascular events and all-cause mortality being reported. Conclusions This systematic review of randomised and non-randomised studies identifies a substantive gap in the literature surrounding the cardiovascular morbidity and mortality of patients using different regimens of insulin. There is a need for more consistent high

    Objective. This study compared the eradication rates of of Helicobacter pylori (HP) infection by a 7-day and 14-day anti-HP regimen. Materials and Methods. An open, randomized, prospective study was performed to evaluate the response to anti-HP treatment in adult HP-positive patients following a 7-day course (Regimen A) of a proton pump inhibitor in association with clarithromycin and amoxicillin compared to a 14-day course (Regimen B). Gastric biopsies were performed at baseline and two months after anti-HP treatment. Results. Seventy-eight patients aged 18–64 years (28 males, 50 females) diagnosed with HP infection were included. Fifty-two (66.7%) patients received Regimen B and 26 (33.3%) Regimen A. The overall eradication rate was 70.5%. Better treatment response (p duodenal lesions in both regimens. Younger patients ≤35 years had a better response to Regimen B. Better treatment response was seen in women, urban residents, and those with tertiary level of education in both groups. Conclusion. 14-day anti-HP regimen offered a significant better overall eradication of HP in study population. PMID:26858750

    Aim of this study was to report the 204-week efficacy and safety results of a novel PI- and NRTI-sparing regimen for salvage therapy including maraviroc, raltegravir, etravirine in 28 failing HIV-infected patients with R5-tropic virus. The trend of laboratory parameters was tested by ANOVA for repeated measures and Greenhouse-Geisser probabilities were reported. Results were described as median (Q1-Q3) values. Twenty-six (93%) out of 28 patients completed 204 weeks of treatment. Virological success (HIV-RNA<50 copies/mL) at week 204 was 96%. CD4+ counts significantly increased [244 (158-213) cells/mm3, p<0.0001] from baseline [247 (68-355) cells/mm(3)] as well as CD4+ percentage. Four serious adverse events (1 death due to Hodgkins's lymphoma, 1 anal cancer, 1 Hodgkins's lymphoma, 1 recurrence of mycobacterial spondylodiscitis) were observed; three events led to transitory discontinuation of the antiretroviral therapy due to drug-drug interaction. BMI (p<0.0001) and waist circumference (p<0.0001) significantly increased over 204 weeks. An amelioration was also observed in relation to haemoglobin (p=0.0006), platelets (p<0.0001), white blood cell (p=0.013), neutrophils (p=0.301), lymphocytes (p=0.207) and creatinine (p<0.0001). In highly treatment-experienced patients the maraviroc, raltegravir and etravirine combination is associated with a good long-term efficacy and safety profile.

    We compared retrospectively the level of hemoglobin and the percentage of patients with anemia among 59 kidney transplant recipients receiving everolimus, cyclosporine, and corticosteroids and 128 treated with cyclosporine, mycophenolic acid, and corticosteroids. We also compared age at the time of transplantation, sex and ferritine, serum creatinine, creatinine clearance, folic acid, cyanocobalamine levels, use od recombinant erythropoietin, mean corpuscolar volume at the last ambulatory control. Statistical analysis included Student t test, χ(2) test, and logistic regression. The analysis was performed using SPSS software. We observed no difference in terms of hemoglobin levels in patients treated with everolimus (12.9 ± 1.6 vs 12.7 ± 1.5 g/dL). Anemia (defined as hemoglobin erythropoietin) was found in 49% and 45% of patients in the 2 groups respectively (P = .6). The other parameters evaluated were similar except for the mean corpuscular volume, which was significantly lower in the everolimus group. In the multivariate analysis only serum creatinine and estimated glomerular filtration rate influenced the level of hemoglobin. We observed no differences in terms of development of anemia in renal transplanted patients treated with everolimus-based regimen. PMID:27109950

    Background A phase Ⅲ trial involving docetaxel, cisplatin, and fluorouracil (DCF) in the treatment of advanced gastric cancer was shown to have superior efficacy compared to cisplatin and fluorouracil alone, but with a high rate of hematologic toxicity. To reduce toxicity while maintaining the efficacy of DCF, we reduced the doses of docetaxel (D) and cis-platinum (CDDP), and administered 5-fluorouracil (5-FU) via a continuous intravenous (CIV) infusion.Methods Chemotherapy-naive patients with gastric adenocarcinomas received D (60 mg/m2 1 hour on day 1), CDDP (30 mg/m2on days 1 and 2), and 5-FU (1500 mg·m-2·24 h-1 CIV on days 1 and 8 every 3 weeks). The primary endpoint was the response rate.Results Fourteen patients were enrolled. Based on the efficacy evaluation following at least 2 cycles of treatment, there was 7.1% complete remission (CR), 71% partial remission (PR), 14% stable disease (NC/SD), and 7.1% progressive disease (PD). The median survival time was 13 months. Nine patients (64%) had grade Ⅲ-Ⅳ neutropenia, and 4 patients (29%) had grade Ⅳ neutropenia, among whom 1 had grade Ⅳ neutropenia with grade Ⅲ nausea and vomiting.Conclusion The modified DCF regimen is highly active and has a favorable toxicity profile in Chinese patients with gastric cancer.

    Objectives To evaluate the prevalence of atrial thrombi in patients with atrial fibrillation undergoing different anticoagulation regimens before cardioversion; to evaluate the usefulness of transoesophageal echocardiography (TOE) guided cardioversion to prevent thromboembolic complications; and to correlate the presence of atrial thrombi with clinical and echocardiographic data. Methods 757 consecutive patients admitted as candidates for cardioversion of atrial fibrillation were enrolled in the study. They were divided into four groups: effective conventional oral anticoagulation, short term anticoagulation, ineffective oral anticoagulation or subtherapeutic anticoagulation, and effective oral anticoagulation with a duration of < 3 weeks for various clinical reasons. All patients underwent TOE before cardioversion; in the presence of atrial thrombi or extreme left atrial echo contrast, cardioversion was postponed. The incidence of thromboembolic events was evaluated after cardioversion. Results Atrial thrombi were detected in 48 of the 757 (6.3%) patients. No significant differences in the percentage of atrial thrombosis were found in the four study groups. Patients with atrial thrombosis were older and had a higher percentage of mitral prosthetic valves, lower left ventricular ejection fraction, more severe atrial spontaneous echo contrast, and lower Doppler left atrial appendage velocities. 648 patients were scheduled for cardioversion. Cardioversion was successful in 89% of patients without any major thromboembolic event. Conclusions The prevalence of atrial thrombosis before cardioversion despite different treatments with anticoagulants is about 7% and a TOE guided approach may prevent the risk of embolic events.

    Patrick S Sullivan

    Full Text Available BACKGROUND: Nonadherence to antiretroviral therapy (ARVT is an important behavioral determinant of the success of ARVT. Nonadherence may lead to virological failure, and increases the risk of development of drug resistance. Understanding the prevalence of nonadherence and associated factors is important to inform secondary HIV prevention efforts. METHODOLOGY/PRINCIPAL FINDINGS: We used data from a cross-sectional interview study of persons with HIV conducted in 18 U.S. states from 2000-2004. We calculated the proportion of nonadherent respondents (took or=4 medications; living in a shelter or on the street; and feeling "blue" >or=14 of the past 30 days. We found weaker associations with having both male-male sex and injection drug use risks for HIV acquisition; being prescribed ARVT for >or=21 months; and being prescribed a protease inhibitor (PI-based regimen not boosted with ritonavir. The median proportion of doses missed was 50%. The most common reasons for missing doses were forgetting and side effects. CONCLUSIONS/SIGNIFICANCE: Self-reported recent nonadherence was high in our study. Our data support increased emphasis on adherence in clinical settings, and additional research on how providers and patients can overcome barriers to adherence.

    Bed rest increases pressure distension in arteries, arterioles, and veins of the leg. We hypothesized that bed-rest-induced deconditioning of leg vessels is governed by the removal of the local increments in transmural pressure induced by assuming erect posture and, therefore, can be counteracted by intermittently increasing local transmural pressure during the bed rest. Ten men underwent 5 wk of horizontal bed rest. A subatmospheric pressure (-90 mmHg) was intermittently applied to one lower leg [pressure habituation (PH) leg]. Vascular pressure distension was investigated before and after the bed rest, both in the PH and control (CN) leg by increasing local distending pressure, stepwise up to +200 mmHg. Vessel diameter and blood flow were measured in the posterior tibial artery and vessel diameter in the posterior tibial vein. In the CN leg, bed rest led to 5-fold and 2.7-fold increments (P pressure-distension and flow responses, respectively, and to a 2-fold increase in tibial vein pressure distension. In the PH leg, arterial pressure-distension and flow responses were unaffected by bed rest, whereas bed rest led to a 1.5-fold increase in venous pressure distension. It thus appears that bed-rest-induced deconditioning of leg arteries, arterioles, and veins is caused by removal of gravity-dependent local pressure loads and may be abolished or alleviated by a local pressure-habituation regimen.

    For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use of other waste-management practices. As a result, summer dissolved-oxygen levels have increased, salmon runs have returned, and the overall effort is widely regarded as a singular water-quality success. To document the improved dissolved-oxygen regimen, the U.S. Geological Survey conducted intensive studies of the Willamette during the summer low-flow seasons of 1973 and 1974. During each summer the mean daily dissolved-oxygen levels were found to be higher than 5 milligrams per liter throughout the river. Because of the basinwide secondary treatment, carbonaceous deoxygenation rates were low. In addition, almost half of the biochemical oxygen demand entering the Willamette was from diffuse (nonpoint) sources rather than outfalls. These results indicated that point-source biochemical oxygen demand was no longer the primary cause of dissolved-oxygen depletion. Instead, the major causes of deoxygenation were nitrification in a shallow ' surface active ' reach below Salem and an anomalous oxygen demand (believed to be primarily of benthal origin) in Portland Harbor.

    The behavioral outcomes of a calorie restricted diet are often neglected in favour of a more physiological examination of the consequences of calorie restriction (CR). This is especially the case with social behavior. A few findings within the maternal CR literature suggest that adult male social behavior is altered by this regimen. Despite the paucity of findings within the maternal CR literature, a systematic investigation of the behavioral phenotype of males administered an adult-onset CR is completely lacking and was the focus of the current study. Adult male hooded Wistar rats were administered a three week CR, with one group receiving a 25% CR and another group receiving a 50% CR before male-to-male social behavior was examined and compared with ad libitium fed males. Various behavioral elements were modulated by CR, both the CR25% and 50% group initiated contact sooner and engaged in greater social activity compared to the ad libitum fed controls. The CR25% group also demonstrated less non-social (self-grooming) behavior and a greater frequency of walkovers compared to all groups, indicating a propensity towards dominance. The CR50% group demonstrated greater environmental assessment/exploration, as measured by the frequency of rearing. As with the maternal CR literature, an adult-onset chronic CR induces a more socially active behavioral phenotype and reduces interest in non-social behavior in the moderately CR group. Taken together, the social behavioral phenotype can be modulated by a CR initiated and maintained during adulthood.

    A search of the Medline database and ASCO 2003 conference proceedings was conducted to identify clinical trials currently underway using single-agent therapy for renal cell carcinoma (RCC). Combination trials were identified using the ASCO 2003 conference proceedings. Fourteen single-agent therapies employing different mechanisms of action were identified in the published literature: imatinib mesylate (Gleevec); bevacizumab (Avastin); thalidomide (Thalomid); gefitinib (ZD1839) (Iressa); cetuximab (IMC-C225) (Erbitux); bortezomib (PS-341) (Velcade); HSPPC-96 (Oncophage); BAY 59-8862; ABT-510; G250; CCI-779; SU5416; PTK/ZK; and ABX-EGF. Six distinct fields of clinical research have emerged: monoclonal antibodies, small molecules, vaccines, second-generation taxanes, nonapeptides and immunomodulators. Five combination regimens, primarily biological response modifiers (interleukin-2 or interferon-alpha), chemotherapy- or thalidomide-based, were identified. All therapies demonstrated acceptable toxicity profiles. Clinical benefit was assessed based on each study's reported criteria: antitumor response (regression or stability) ranged from 5% to 71%. In the past several years, significant advances in the underlying biological mechanisms of RCC, particularly the role of tumor angiogenesis, have permitted the design of molecularly targeted therapeutics. Based on preliminary and limited studies, combination therapies offer the greatest clinical benefit in the management of this malignancy, although additional basic research is still warranted.

    In this study, the effect of genetic constitution (stock) and rearing temperature on the occurrence of hemorrhages in thighs and breasts of water bath stunned broilers was investigated. Particular attention was given to the relation between the susceptibility for hemorrhages, body composition, and adaptations in blood variables induced by low rearing temperatures. A factorial experiment was performed with five parental stocks, differing with respect to growth rate, feed conversion, and body composition, and two temperature regimens (thermoneutral and below the zone of thermoneutrality). Hemorrhage scores in thighs were dependent on rearing temperature, not on stock, and were highest in broilers reared at low temperatures. In all stocks, high scores in the thighs were accompanied by an increased carbon dioxide pressure and bicarbonate and triiodothyronine concentration of the venous blood, and by an increased relative heart weight, hematocrit, and blood loss at slaughter. Hemorrhage scores in breasts were dependent on stock, confounded with day of scoring. An effect of rearing temperature was present only for the leanest, slow-growing stock having the lowest feed conversion ratio at thermoneutral rearing conditions. Scores in breasts were related neither to body composition nor to metabolic and hemodynamic adaptations to low rearing temperatures. It is concluded that high hemorrhage scores in thighs are related to hemodynamic and metabolic adaptations to an increased need for energy and oxygen caused by low rearing temperatures. Hemorrhage scores are not related to stock-dependent differences. PMID:9495502

    Full Text Available Hepatic cirrhosis is one of the leading causes of death worldwide, especially if complicated by ascites. This chronic condition can be related to the classical disease entity jalodara in Traditional Indian Medicine (Ayurveda. The present paper aims to evaluate the general potential of Ayurvedic therapy for overall clinical outcomes in hepatic cirrhosis complicated by ascites (HCcA. In form of a nonrandomized, uncontrolled, single group, open-label observational clinical study, 56 patients fulfilling standardized diagnostic criteria for HCcA were observed during their treatment at the P. D. Patel Ayurveda Hospital, Nadiad, India. Based on Ayurvedic tradition, a standardized treatment protocol was developed and implemented, consisting of oral administration of single and compound herbal preparations combined with purificatory measures as well as dietary and lifestyle regimens. The outcomes were assessed by measuring liver functions through specific clinical features and laboratory parameters and by evaluating the Child-Pugh prognostic grade score. After 6 weeks of treatment and a follow-up period of 18 weeks, the outcomes showed statistically significant and clinically relevant improvements. Further larger and randomized trials on effectiveness, safety, and quality of the Ayurvedic approach in the treatment of HCcA are warranted to support these preliminary findings.

    Two ultraviolet A (UVA) regimens for oral 8-methoxypsoralen (8-MOP) photochemotherapy (PUVA) for moderate/severe chronic plaque psoriasis using a half-body study technique were compared. Each patient received both regimens. A higher-dose regimen based on minimal phototoxic dose (MPD) with percentage incremental increases was given to one-half of the body. The other half received a lower dose regimen based on skin type with fixed incremental UVA increases. Patients were treated twice weekly. Symmetrical plaques were scored to determine the rate of resolution with each regimen. In addition, the number of treatments, cumulative UVA dose and number of days in treatment to achieve overall clearance were recorded. Patients were reviewed monthly for one year to record remission data. Thirty-three patients completed the study. Both regimens were effective and well tolerated. With the MPD-based approach, number of exposures was significantly less for patients with skin types I and II but not III. Although the cumulative UVA dose was higher with the MPD regimen for all skin types studied, the reduced number of exposures required for clearance for skin types I and II but not III, combined with the security of individualized MPD testing, has practical attractions. MPD testing also identified five patients who required an increased psoralen dose and six patients who required a reduction of the initial UVA dose with the skin type regimen. Forty-two percent were still clear 1 year after treatment and there was no significant difference in the number of days in remission between the regimens for those whose psoriasis had recurred. The reduction in the number of exposures required for clearance with the MPD-based regimen may be safer and more cost effective in the long term. (author).

    2015-08-15

    Human onchocerciasis (river blindness), caused by the filarial nematode Onchocerca volvulus, has been successfully controlled by a single drug, ivermectin, for over 25 years. Ivermectin prevents the disease symptoms of severe itching and visual impairment by killing the microfilarial stage, but does not eliminate the adult parasites, necessitating repeated annual treatments. Mass drug administration with ivermectin does not always break transmission in forest zones and is contraindicated in individuals heavily co-infected with Loa loa, while reports of reduced drug efficacy in Ghana and Cameroon may signal the development of resistance. An alternative treatment for onchocerciasis involves targeting the essential Wolbachia symbiont with tetracycline or its derivatives, which are adulticidal. However, implementation of antibiotic therapy has not occurred on a wide scale due to the prolonged treatment regimen required (several weeks). In the bovine Onchocerca ochengi system, it has been shown previously that prolonged oxytetracycline therapy increases eosinophil counts in intradermal nodules, which kill the adult worms by degranulating on their surface. Here, in an "immunochemotherapeutic" approach, we sought to enhance the efficacy of a short, sub-lethal antibiotic regimen against O. ochengi by prior immunotherapy targeting onchocystatin, an immunomodulatory protein located in the adult female worm cuticle. A key asparagine residue in onchocystatin was mutated to ablate immunomodulatory activity, which has been demonstrated previously to markedly improve the protective efficacy of this vaccine candidate when used as an immunoprophylactic. The immunochemotherapeutic regimen was compared with sub-lethal oxytetracycline therapy alone; onchocystatin immunotherapy alone; a gold-standard prolonged, intermittent oxytetracycline regimen; and no treatment (negative control) in naturally infected Cameroonian cattle. Readouts were collected over one year and comprised adult

    Several studies reported improved outcomes of adolescents and young adults (AYA) with acute lymphoblastic leukemia (ALL) treated with pediatric-based ALL regimens. This prompted the prospective investigation of a pediatric Augmented Berlin-Frankfurt-Münster (ABFM) regimen, and its comparison with hyper-fractionated cyclophosphamide, vincristine, Adriamycin, and dexamethasone (hyper-CVAD) in AYA patients. One hundred and six AYA patients (median age 22 years) with Philadelphia chromosome- (Ph) negative ALL received ABFM from October 2006 through March 2014. Their outcome was compared to 102 AYA patients (median age 27 years), treated with hyper-CVAD at our institution. The complete remission (CR) rate was 93% with ABFM and 98% with hyper-CVAD. The 5-year complete remission duration (CRD) were 53 and 55%, respectively (P = 0.98). The 5-year overall survival (OS) rates were 60 and 60%, respectively. The MRD status on Day 29 and Day 84 of therapy was predictive of long-term outcomes on both ABFM and hyper-CVAD. Severe regimen toxicities with ABFM included hepatotoxicity in 41%, pancreatitis in 11%, osteonecrosis in 9%, and thrombosis in 19%. Myelosuppression-associated complications were most significant with hyper-CVAD. In summary, ABFM and hyper-CVAD resulted in similar efficacy outcomes, but were associated with different toxicity profiles, asparaginase-related with ABFM and myelosuppression-related with hyper-CVAD.

    A new dose regimen of artesunate and amodiaquine (NDRAA) based on age or body weight range was compared with standard dose regimen of artesunate and amodiaquine (SDRAA) calculated according to body weight and with fixed-dose artesunate-amodiaquine (FDAA) and artemether-lumefantrine (AL) in 304 children afflicted by malaria aged 15 years or younger. In initial comparison (n = 208), children on NDRAA received 1-3 times amodiaquine per kilogram of body weight and 1-1.5 times of artesunate per kilogram of body weight compared with those receiving SDRAA. Parasite but not fever clearance was significantly faster in children who received NDRAA (19.4 ± 8.4 hours vs. 24.6 ± 15.5 hours, P = 0.003). Polymerase chain reaction-uncorrected cure rates on days 28-42 were also significantly higher in children who received NDRAA (P < 0.02 in all cases). Therapeutic responses in children younger than 5 years (n = 96) treated with NDRAA, FDAA, and AL were similar. Changes in hematocrit values and reported adverse events after commencing therapy were similar in those who received NDRAA and SDRAA. All drug regimens were well tolerated. NDRAA based on age or body weight range is simple, is therapeutically superior to SDRAA calculated according to body weight, and is as efficacious as AL in children younger than 5 years.

    2014-01-01

    Full Text Available Renexin, a compound of cilostazol and ginkgo biloba extract, has been reported to produce neuroprotective effects through antioxidant, antiplatelet, and vasodilatory mechanisms. This study was designed to investigate the protective effects of renexin on hearing, the organ of Corti (OC, and medial olivocochlear efferents against noise-induced damage. C57BL/6 mice were exposed to 110 dB SPL white noise for 60 min and then randomly divided into three groups: high- and low-dose renexin-treated groups and noise only group. Renexin were administered for 7 days: 90 mg/kg to the low-dose, and 180 mg/kg to the high-dose groups. All mice, including the controls underwent hearing tests on postnoise day 8 and were killed for cochlear harvest. We compared the hearing thresholds and morphology of the OC and cochlear efferents across the groups. The renexin-treated groups recovered from the immediate threshold shifts in a dose-dependent manner, while the noise group showed a permanent hearing loss. The renexin-treated ears demonstrated less degeneration of the OC. The diameters of the efferent terminals labeled with α-synuclein were preserved in the high-dose renexin-treated group. In the western blot assay of the cochlear homogenates, the treated groups displayed stronger expressions of α-synuclein than the noise and control groups, which may indicate that noise-induced enhanced activity of the cochlear efferent system was protected by renexin. Our results suggest that pharmacologic treatment with renexin is hopeful to reduce or prevent noise-induced hearing loss as a rescue regimen after noise exposure.

  18. Comparison of radiation regimens in the treatment of Glioblastoma multiforme: results from a single institution

    International Nuclear Information System (INIS)

    The optimal fractionation schedule of radiotherapy (RT) for Glioblastoma multiforme (GBM) is yet to be determined. We aim to compare different fractionation regimens and identify prognostic factors to better tailor RT for newly diagnosed GBM patients. All data for patients who underwent surgery for GBM between January 2005 and December 2012 were compiled. Clinical information was collected using patient charts and government registry. Cox analysis was used to identify variables affecting survival and treatment outcome. The median follow-up time was 13.2 months. Two hundred and seventy-six patients met the inclusion criteria, including 147 patients in the 60 Gy in 30 fractions (ConvRT) group, 86 patients in the 60 Gy in 20 fractions (HF60) group, and 43 patients in the 40 Gy in 15 fractions (HF40) group. Median survival (MS) was 16.0 months with a median progression-free survival (PFS) of 9.23 months in the ConvRT group. This was comparable to outcome in the HF60 group with MS 15.0 months and a median PFS of 9.1 months. Patients in the HF40 group had MS of 8 months, with a median PFS 5.4 months. Cox analysis showed no significant difference in OS between the ConvRT and HF60 groups but worse outcome in the HF40 group (HR 2.22, P = 0.04). MGMT methylation, extent of resection, use of chemotherapy, and repeat surgery were found to be significant independent prognostic factors for survival. HF60 constitutes a safe RT approach that shows survival comparable to standard RT while allowing for a shorter treatment time

    The objective of this study was to determine if a single loading dose (LD), 3× the label dose of firocoxib oral paste, followed by nine maintenance doses at the current label dose achieves and maintains near steady state concentrations. Six healthy, adult mares were administered 0.3mg/kg of firocoxib on Day 0, and 0.1 mg/kg 24 h later on Day 1, and at 24 h intervals from Day 2 to Day 9, for a total of 10 doses. Blood samples were collected throughout the study. The mean firocoxib maximum plasma concentration and standard deviation was 199±97 ng/mL, 175±44 ng/mL and 183±50 ng/mL after the LD, and first and last maintenance doses, respectively. The minimum mean concentration (C(min)) increased from 100±23 ng/mL after the LD to 132±38 ng/mL at Day 7. Then, the C(min) remained constant until Day 9. The average concentration at steady state (C(avg)) was 150±45 ng/mL, which compares well to the C(avg) (130±36 ng/mL) reported after multiple daily doses at 0.1 mg/kg. The administration of the single LD allowed achievement of the average steady state drug concentrations faster than a multi-dose regimen without a loading dose. After the LD, firocoxib at 0.1 mg/kg every 24 h was able to maintain a relatively constant average drug concentration which should produce less variability in onset of action and efficacy.

    Full Text Available In this study, efficacies of different therapeutic regimens along with 10% zinc-sulfate footbath for the treatment of acute foot rot in adult sheep were evaluated. The research work conducted on the adult sheep (n=104 of both sexes which were presented to the Teaching Veterinary Clinical Complex during April 2013 to May 2014. Foot rot was confirmed based on clinical and physical examinations. The sheep were divided into four equal groups; G-I, G-II, G-III, and G-IV. The animals of the G-I, II and IV were treated with a mixture of amoxicillin and cloxacillin at 15 mg/kg body weight (b.wt. through intramuscular (IM route, oxytetracycline at 20 mg/kg b.wt., IM, and enrofloxacin at 5 mg/kg b.wt., IM, respectively. The animals of G-III were treated with gamma benzene hexachloride cream. Along with the above treatments, all four groups were given footbath with 10% zinc-sulfate. Mean recovery time (days was recorded as lowest in G-II (3.83±0.64 followed by G-I (4.17±0.31, G-IV (4.38±0.0.79 and G-III (5.67±0.98, respectively. The mean±SE values of rectal temperature and ruminal motility that were recorded before and after the treatment showed significant (p<0.05 differences. In conclusion, administration of parenteral antibiotics in combination with footbath was highly effective to treat combination with footbath was highly effective to treat the acute foot rot in sheep.

    Infections caused by vancomycin-resistant enterococci (VRE) may be difficult to treat because of the limited armamentarium of antimicrobial agents. The difficulty is compounded in pediatric patients in general and neonates in particular because many of the newer antimicrobials have not been studied or approved for children. We report a 3-week-old infant who developed enterococcal bacteremia on post-operative day 10 after a surgical palliation for complex congenital heart disease that was complicated by acute renal failure. Despite removal of vascular catheters and antimicrobial regimens that included linezolid, quinupristin/dalfopristin, ampicillin/sulbactam, rifampin, and gentamicin, bacteremia persisted. It was not cleared until daptomycin (in combination with doxycycline) was started. This is the first case of successful treatment of probable endocarditis due to VRE in a neonate using a daptomycin-containing regimen. PMID:21694874

    Full Text Available Introduction: An association of persistent low level viremia (LLV below 500 copies/mL and a higher risk of therapy failure is still point of controversial discussion. Furthermore, it seems that LLV occurs more frequently in patients with protease-inhibitor regimens than in NNRTI- / or integrase-inhibitor containing therapies. The focus of this work was to assess the prevalence of LLV (50–200 copies/mL and weak viremia (201–500 copies/mL in firstline-treated patients according to their therapy regimen. Methods: A total of 832 and 944 patients from 23 German centres were under firstline therapy in 2012 and 2013, respectively. All patients received their therapy for more than 24 weeks. VL data was related to clinical data retrospectively including ART-composition, subdivided into NNRTIs (Efavirenz, Nevirapine, PIs (Atazanavir, Darunavir, Lopinavir and INIs (Raltegravir. Low viremic patients were classified into two arms of 50–200 copies/mL (group A and 201–500 copies/mL (group B. Results: Success of therapy was defined as <50 copies/mL and was observed in 90.0% and 91.1% (2012/2013, respectively. An additional 2.0% and 2.3% had LLV. The amount of viremic patients with VLs <500 copies/mL differed significantly between NNRTI-based firstline regimens 1.7% and 2.5% and PI-based regimens 4.8% and 5.7% (2012/2013, respectively. LLV was clearly less often observed in EFV-based- (1.6% and 1.1% [group A] / 0.4% and 0.4% [group B] or NVP-based firstline therapies (1.0% and 3.6% [group A] + 0% and 0% [group B] than in ATV-based- (7.5% and 3.8% [group A] + 1.5% and 2.5% [group B], DRV-based- (2.9% and 3.0% [group A] + 2.2% and 0% [group B] or LPV-based firstline therapies (1.6% and 3.3% [group A] + 0.8% and 2.5% [group B] and also in parts for RAL-based regimens (0% and 3.7% [group A] + 0% and 1.9% [group B]. Conclusions: LLV is more often observed under PI-based firstline than under NNRTI-regimens. Only one NNRTI-patient of group B remained on therapy

    Studies have shown that cancer requires two conditions for tumor progression: cancer cell proliferation and an environment permissive to and conditioned by malignancy. Chemotherapy aims to control the number and proliferation of cancer cells, but it does not effectively control the two best-known conditions of the tumor-permissive environment: neoangiogenesis and tolerogenic immunity. Many malignant diseases exhibit poor outcomes after treatment with chemotherapy. Therefore, we investigated the potential benefits of adding an induction regimen of antiangiogenesis and antitumor immunity to chemotherapy in poor outcome disease. In a prospective, randomized trial, we included patients with advanced, unresectable pancreatic adenocarcinomas, non-small cell lung cancer, or prostate cancer. Two groups of each primary condition were compared: group 1 (G1), n = 30, was treated with the standard chemotherapy and used as a control, and group 2 (G2), n = 30, was treated with chemotherapy plus an induction regimen of antiangiogenesis and antitumor immunity. This induction regimen included a low dose of metronomic cyclophosphamide, a high dose of Cox-2 inhibitor, granulocyte colony-stimulating factor, a sulfhydryl (SH) donor, and a hemoderivative that contained autologous tumor antigens released from patient tumors into the blood. After treatment, the G2 group demonstrated significantly longer survival, lower blood level of neoangiogenesis and immune-tolerance mediators, and higher blood levels of antiangiogenesis and antitumor immunity mediators compared with the G1 group. Toxicity and quality of life were not significantly different between the groups. In conclusion, in several advanced malignancies of different primary localizations, an increase in survival was observed by adding an induction regimen of antiangiogenesis and antitumor immunity to standard chemotherapy.

    Onchocerciasis (river blindness), caused by the filarial nematode Onchocerca volvulus, is a major cause of visual impairment and dermatitis in sub-Saharan Africa. As O. volvulus contains an obligatory bacterial symbiont (Wolbachia), it is susceptible to antibiotic chemotherapy, although current regimens are considered too prolonged for community-level control programs. The aim of this study was to compare the efficacies of oxytetracycline and rifampin, administered separately or in combinatio...

    Full Text Available BACKGROUND: Intermittent preventive treatment (IPT is a promising malaria control strategy; however, the optimal regimen remains unclear. We conducted a randomized, single-blinded, placebo-controlled trial to evaluate the efficacy, safety, and tolerability of a single course of sulfadoxine-pyrimethamine (SP, amodiaquine + SP (AQ+SP or dihydroartemisinin-piperaquine (DP among schoolchildren to inform IPT. METHODS: Asymptomatic girls aged 8 to 12 years and boys aged 8 to 14 years enrolled in two primary schools in Tororo, Uganda were randomized to receive one of the study regimens or placebo, regardless of presence of parasitemia at enrollment, and followed for 42 days. The primary outcome was risk of parasitemia at 42 days. Survival analysis was used to assess differences between regimens. RESULTS: Of 780 enrolled participants, 769 (98.6% completed follow-up and were assigned a treatment outcome. The risk of parasitemia at 42 days varied significantly between DP (11.7% [95% confidence interval (CI: 7.9, 17.1], AQ+SP (44.3% [37.6, 51.5], and SP (79.7% [95% CI: 73.6, 85.2], p<0.001. The risk of parasitemia in SP-treated children was no different than in those receiving placebo (84.6% [95% CI: 79.1, 89.3], p = 0.22. No serious adverse events occurred, but AQ+SP was associated with increased risk of vomiting compared to placebo (13.0% [95% CI: 9.1, 18.5] vs. 4.7% [95% CI: 2.5, 8.8], respectively, p = 0.003. CONCLUSIONS: DP was the most efficacious and well-tolerated regimen tested, although AQ+SP appears to be a suitable alternative for IPT in schoolchildren. Use of SP for IPT may not be appropriate in areas with high-level SP resistance in Africa. TRIAL REGISTRATION: ClinicalTrials.gov NCT00852371.

    Purpose Nausea and vomiting are among the most feared complications of chemotherapy reported by patients. The objective of this study was to establish the overall complete response (CR; no emesis or use of rescue medication 0–120 h after chemotherapy) with either ondansetron- or palonosetron-containing antiemetic regimens in patients receiving highly emetogenic chemotherapy (HEC). Methods This was a prospective, open-label, randomized, single-center, pilot study that enrolled patients receiving their first cycle of HEC. Patients were randomized to receive either palonosetron 0.25 mg IV (PAD) or ondansetron 24 mg orally (OAD) on day 1 prior to HEC. All patients received oral aprepitant 125 mg on day 1, then 80 mg on days 2 and 3, and oral dexamethasone 12 mg on day 1, then 8 mg on days 2, 3, and 4. Descriptive statistics were used to summarize the data. Results A total of 40 patients were enrolled, 20 in each arm. All patients were female, and 39 received doxorubicin/cyclophosphamide chemotherapy for breast cancer. For the primary endpoint, 65 % (95 % CI, 40.8–84.6 %) of patients in the PAD arm and 40 % (95 % CI, 19.1–63.9 %) of patients in the OAD arm achieved an overall CR. Conclusions While CR rates for aprepitant and dexamethasone plus palonosetron or ondansetron-containing regimens have been published previously, this is the first documentation of CR rates with these regimens in the same patient population. These results may be used to design a larger, adequately powered, prospective study comparing these regimens. PMID:23748485

    The purpose of this study was to compare survival and risk of adverse events in women with early stage breast cancer (BC) treated with (1) doxorubicin (A), cyclophosphamide (C) + paclitaxel (P), (2) fluorouracil (F), epirubicin (E), cyclophosphamide (C) + docetaxel (D), or (3) dose-dense AC-P. Retrospective cohort study including 8462 women aged ≥18 years, with resected stage I-III BC, diagnosed between 2003 and 2009 in Ontario, identified through linkage of administrative databases. Primary outcome is overall survival (OS). Secondary outcomes are emergency room (ER) visits/hospitalizations, heart failure (HF), and leukemia. 4710 women were treated with FEC-D, 2065 with AC-P, and 1687 with dd AC-P. Adjusted 5-year OS was 92.1, 87.7, and 90.3 %, for each regimen, respectively (p = 0.0006). There was no difference in OS for FEC-D and dd AC-P in the propensity score-matched analyses (HR 1.24, 95 % CI 0.99-1.55). Five-year risk of HF was also similar (HR 1.09; 0.66-1.791.4 % for dd AC-P and 1.3 % for FEC-D and, p = 0.72). Treatment with FEC-D was significantly associated with ER visits and hospital admissions (p < 0.0001). The risks of leukemia were low and similar among the 3 groups (AC-P: 0.34 %, FEC-D: 0.08 %, dd AC-P: 0.12 %; p = 0.09). Although the efficacy of the three regimens was similar to that observed in randomized trials, we report higher toxicity with the use of these regimens in clinical practice. This was especially concerning for the docetaxel-containing regimen.

    The introduction of agents such as thalidomide, lenalidomide, and bortezomib has changed the management of patients with multiple myeloma who are not eligible for autologous transplantation, many of whom are elderly. We sought to compare three thalidomide-based oral regimens among such patients in Latin America. We randomized patients with newly diagnosed multiple myeloma with measurable disease to one of the following regimens: melphalan, prednisone, and thalidomide (MPT); cyclophosphamide, thalidomide, and dexamethasone (CTD); and thalidomide and dexamethasone (TD). The TD arm was closed prematurely and was analyzed only descriptively. The primary endpoint was the overall response rate (ORR), whereas progression-free survival (PFS) and overall survival (OS) were secondary endpoints. The accrual rate was slower than expected, and the study was terminated after 82 patients had been randomized. The ORRs were 67.9 % with MPT, 89.7 % with CTD, and 68.7 % with TD (p = 0.056 for the comparison between MPT and CTD). The median PFS was 24.1 months for MPT, 25.9 months for CTD, and 21.5 months for TD. There were no statistically significant differences in PFS or OS between MPT and CTD. In an unplanned logistic regression analysis, ORR was significantly associated with treatment with CTD (p = 0.046) and with performance status of 0 or 1 (p = 0.035). Based on the current results, no definitive recommendations can be made regarding the comparative merit of the regimens tested. Nevertheless and until the results of further studies become available, we recommend either CTD or MPT as suitable frontline regimens for patients with multiple myeloma who are not candidates to transplantation in settings where lenalidomide and bortezomib are not available.

    Full Text Available Limited data are available on the durability and effectiveness of maraviroc in routine clinical practice. We assessed the durability of maraviroc-containing regimens during a 30-month period, as well as their immunovirological and clinical efficacy, according to viral tropism in treatment-experienced individuals with viral load (VL >50 copies/ml in the French Hospital Database on HIV.Virological success was defined as VL50 copies/ml of whom 223 harbored R5 viruses, 44 non-R5 viruses and 89 viruses of unknown tropism. Individuals with non-R5 viruses were more likely than individuals with R5 viruses to discontinue maraviroc (75% vs 34%, p<0.0001. At 30 months, the estimated rates of virological and immunological success were respectively 89% and 51% in individuals with R5 viruses and 48% and 23% in individuals with non-R5 viruses. In multivariable analysis, non-R5 viruses were associated with a lower likelihood of both virological success (hazard ratio (HR: 0.42; 95% confidence interval (CI, 0.25-0.70 and immunological success (HR: 0.37; 95% CI, 0.18-0.77. No difference in clinical outcome was found between individuals with R5 and non-R5 viruses. The effectiveness of maraviroc-containing regimens in individuals with unknown viral tropism was not significantly different from that in individuals with R5 viruses. A limitation of the study is the absence of genotypic susceptibility score.In this observational study, maraviroc-containing regimens yielded high rates of viral suppression and immunological responses in individuals with R5 viruses in whom prior regimens had failed.

    Background The benefit of neoadjuvant chemotherapy in the management of head and neck squamous cell carcinomas (HNSCC) still remains controversial. The aim of this meta-analysis is to evaluate the role of the neoadjuvant chemotherapy with the cisplatin and fluororacil (PF) regimen in enhancing the overall survival of and decreasing locoregional relapse and distant metastasis in HNSCC patients.Methods Medline and manual searches were performed to identify all published randomized controlled trials (RCTs) investigating the efficacy of the neoadjuvant chemotherapy with the PF regimen. Outcomes assessed by meta-analysis included Iocoregional relapse, distant metastasis, and overall survival. The odds ratio was the principle measurement of effect, which was calculated as the treatment group (chemotherapy plus Iocoregional treatment) versus the control group (Iocoregional treatment alone) and was presented as a point estimate with 95% confidence intervals (Cl).Results Eight RCTs were adopted for analysis. The meta-analysis showed that the odds ratio for the Iocoregional relapse was 0.92 (0.70-1.22, 95%Cl), which was not statistically significant. The odds ratios for distant metastasis and overall survival were 0.47 (0.33-0.68, 95% Cl) and 1.28 (1.01-1.62, 95% Cl) respectively, which were both statistically significant.Conclusions Neoadjuvant chemotherapy with the PF regimen in HNSCC patients has no effect on Iocoregional relapse. However, it shows a small but significant benefit in reducing distant metastasis and improving the overall survival.

    Oak barrels have long been the preferred method for oak maturation of wine, but barrels contribute significantly to production costs, so alternate oak maturation regimens have been introduced, particularly for wines at lower price points. To date, few studies have investigated consumers' acceptance of wines made using non-traditional oak treatments. In this study, two Cabernet Sauvignon wines were aged using traditional (i.e., barrel) and/or alternative (i.e., stainless steel or plastic tanks and vats, with oak wood added) maturation regimens. Chemical and sensory analyses were subsequently performed to determine the influence on wine composition and sensory properties, that is, the presence of key oak-derived volatile compounds and perceptible oak aromas and flavor. The quality of a subset of wines was rated by a panel of 10 wine experts using a 20-point scoring system, with all wines considered technically sound. Consumer acceptance of wines was also determined. Hedonic ratings ranged from 5.7 to 5.9 (on a 9-point scale), indicating there was no significant difference in consumers' overall liking of each wine. However, segmentation based on individual liking scores identified three distinct clusters comprising consumers with considerably different wine preferences. These results justify wine producers' use of alternative oak maturation regimens to achieve wine styles that appeal to different segments of their target market.

    Psoriasis is a chronic inflammatory skin disease with a profound effect on quality of life and psychosocial stress. The relationship between clinical improvement and psycho-social impact after treatment is complex. The objective of this study was to compare changes in quality of life and psychosocial distress, and overall cost-effectiveness, in patients with psoriasis receiving the modified Goeckerman regimen (UV irradiation and coal tar) with those receiving conventional treatment. Patients with moderate/severe psoriasis receiving the Goeckerman regimen were followed from admission to discharge. Clinical severity, was evaluated weekly using the Psoriasis Area and Severity Index (PASI). Psoriasis Disability Index (PDI) and Hospital Anxiety and Depression Scale (HADS) questionnaires were applied at admission and one month after discharge. Thirty-six patients with psoriasis receiving conventional treatment and 48 patients receiving the Goeckerman regimen were recruited to the study. The mean PASI score in the Goeckerman group decreased from 27.1 to 6.9 and PDI scores decreased from 25.3 to 13.8. HADS scores for anxiety and depression decreased significantly from 9.8 to 6.3 and 9.1 to 6.8, respectively. In comparison with conventional therapy, the modified Goeckerman regime showed similar clinical efficacy, with additional benefits in improving overall quality of life and psychosocial distress in patients with moderate/severe psoriasis, and more cost-effectiveness.

    A health-economic study of newly formed skin tears and stage II ulcers used an unblinded, comparative, parallel-group design to evaluate two topical regimens as to time required for complete healing and assessment of cost minimization. Thirty-six elderly patients, at risk for developing indolent wounds of the skin and underlying tissues, were assigned to receive either a saline spray and a topical antibiotic ointment (TAM, n = 14) or Dermagran Spray and Dermagran Ointment (DSO, n = 22). The 76 wounds that appeared in these patients had comparable pretreatment surface areas of 3.73 +/- 0.96 cm2 in the DSO group versus 5.57 +/- 1.13 cm2 in the TAM group (P = NS). All wounds were treated twice daily, starting within 24 hours of their appearance, until complete healing. The 19 wounds in the TAM group healed within 48.0 +/- 25.3 days versus 15.4 +/- 1.9 days for the 57 wounds in the DSO group (P < .05). The cost of wound management for a given patient was calculated by adding the costs of nursing labor and the amount of product consumed to effect complete healing. To this end, the cost of the TAM regimen was $323.23 +/- 171.70 versus $104.75 +/- 12.92 for the DSO regimen (P < .05). Results are presented in light of the increasing pressure on long-term care facilities to provide effective and affordable treatment.

    Capecitabine (Xeloda), Roche Laboratories Inc., Nutley, NJ) is an orally administered fluoropyrimidine carbamate that serves as a prodrug of 5-fluorouracil (5-FU), an integral component of chemotherapy (CT) regimens for metastatic colorectal cancer (mCRC). As the drug is orally administered, capecitabine permits greater convenience and flexibility in dosing by eliminating the need for continuous infusion and its potential complications. In phase 3 trials, capecitabine has been used as an alternative to 5-FU, both as a monotherapy and in combination with agents such as oxaliplatin (as XELOX), with good efficacy and tolerability. Combination therapy with capecitabine and irinotecan (XELIRI), however, has produced more variable results, with some dose combinations and schedules resulting in excessive and/or unexplained treatment-related toxicity. Recent initiatives using lower doses of capecitabine and irinotecan, as well as alternative dosing schedules, have resulted in more favorable outcomes (efficacy and tolerability), even in combination with targeted-agents such as bevacizumab. Dose reduction in elderly populations and in those with moderate renal impairment also appears to be important for minimizing toxicity with XELIRI regimens. Although additional phase 3 studies are needed, XELIRI may be an effective base CT regimen, allowing a greater number of treatment options for tumor control in patients with mCRC.

    There are currently no conventional guidelines for radiotherapy in gliomas. The treatment program is mainly formed in accordance with tumor morphology and the "golden standard" of irradiation is still the traditional mode of fractionation with a single focal dose of 2 Gy and total focal dose (TFD) of 60 Gy. In this report the treatment results of 396 patients with morphologically verified grade 3-4 malignant brain tumors receiving conventional irradiation regimen and irradiation by medium-sized fractions were analyzed to form institutional guidelines. The standard fractionation mode with a single focal dose of 2 Gy is preferable in patients with grade 3 glioma or elderly patients (over 60 years). TFD increase to 60-62 Gy in grade 4 gliomas and 54-56 Gy in grade 3 gliomas grants a significant improve in overall survival. An increase of a single irradiation fraction to 3 Gy may be used for patients younger than 60 years. In these cases it is advisable to use the TFD of 45 Gy or more (TFD of equivalent regimen with a dose greater than 54 Gy). The mentioned fractionation regimens could be recommended for the use in clinical practice to improve the results of high-grade gliomas treatment. PMID:22888654

    Background. We examined the efficacy of a new regimen to treat AGA, with attention to male patients who are atopic. Objective. To assess the efficacy of a four-part regimen for the treatment of AGA in atopic and nonatopic patients. NuH Hair is a novel topical combination of finasteride, dutasteride, and minoxidil, which is blended in a hypoallergenic lotion. The other three components included Rogaine foam, Propecia, and ketoconazole shampoo. Methods. A prospective pilot study was conducted in 15 patients. All patients were assessed for the presence of atopy. Each patient served as their own control. All patients were treated specifically with NuH Hair and were given the option to add any of the other components of the protocol to their regimen. Photographs were taken of each patient's scalp at months 0, 1, 3, 6, and 9. Results. All 15 patients demonstrated significant growth of hair. In those patients who utilized all 4 components, significant growth was achieved in as little as 30 days. In those patients who choose only to utilize NuH Hair, significant growth was demonstrated after 3 months. Conclusion. Aggressively treating AGA achieves significant and rapid growth of new hair. This is effective in atopic and nonatopic male patients. PMID:22363845

    Full Text Available Standard short course chemotherapy is recommended by the World Health Organization to control tuberculosis worldwide. However, in settings with high drug resistance, first line standard regimens are linked with high treatment failure. We evaluated treatment outcomes after standardized chemotherapy with the WHO recommended category II retreatment regimen in a prison with a high prevalence of drug resistant tuberculosis (TB. A cohort of 233 culture positive TB patients was followed through smear microscopy, culture, drug susceptibility testing and DNA fingerprinting at baseline, after 3 months and at the end of treatment. Overall 172 patients (74% became culture negative, while 43 (18% remained positive at the end of treatment. Among those 43 cases, 58% of failures were determined to be due to treatment with an inadequate drug regimen and 42% to either an initial mixed infection or re-infection while under treatment. Overall, drug resistance amplification during treatment occurred in 3.4% of the patient cohort. This study demonstrates that treatment failure is linked to initial drug resistance, that amplification of drug resistance occurs, and that mixed infection and re-infection during standard treatment contribute to treatment failure in confined settings with high prevalence of drug resistance.

    We examined the real-world utilization and persistence of rapid acting insulin (RAI) in elderly patients with type 2 diabetes who added RAI to their drug (OAD) regimen. Insulin-naïve patients aged ≥65 years, with ≥1 OAD prescription during the baseline period, who were continuously enrolled in the US Humana Medicare Advantage insurance plan for 18 months and initiated RAI were included. Among patients with ≥2 RAI prescriptions (RAIp), persistence during the 12-month follow-up was assessed. Multivariate logistic regression analyses identified factors affecting RAI use and persistence. Of 3734 patients adding RAI to their OAD regimen, 2334 (62.5%) had a RAIp during follow-up. Factors associated with RAIp included using ≤2 OADs; cognitive impairment, basal insulin use during follow-up; and higher RAI out-of-pocket costs ($36 to <$56 versus $0 to $6.30). Patients were less likely to persist with RAI when on ≤2 OADs versus ≥3 OADs and when having higher RAI out-of-pocket costs ($36 to <$56 versus $0 to $6.30) and more likely to persist when they had cognitive impairment and basal insulin use during follow-up. Real-world persistence of RAI in insulin-naïve elderly patients with type 2 diabetes was very poor when RAI was added to an OAD regimen. PMID:27761472

    Exogenous gonadotropins are used to stimulate ovarian follicular growth and ovulation in mammalian species, including wild cats. However, successes in application of assisted reproduction techniques in nondomestic felids have been sparse. Our objectives were to assess the effectiveness of alternating gonadotropin regimens on ovarian responses. Five adult female ocelots and four adult female tigrinus were treated four to six times, using alternating eCG/hCG and pFSH/pLH at 4-month intervals. Laparoscopies were done to assess follicular development and to collect oocytes from matures follicles. The average number of follicles and corpus luteum (CL) per stimulation was higher in ocelots (7.0 +/- 0.8; mean +/- S.E.M.) than in tigrinus (2.5 +/- 0.4; P < 0.05), but the percentage of mature oocytes did not differ between the two species (mean range, 54-55%). Within species, both gonadotropin regimens were equally effective in inducing follicular growth and oocyte maturation. The total number of ovarian structures and oocyte maturation percentages did not decrease in either species with sequential stimulations. In summary, female ocelots and tigrinus continued to respond to repeated alternating ovarian stimulation protocols. In conclusion, the use of alternating gonadotropin regimens may permit more intensive reproductive management in these endangered cats. PMID:16472853

    Creating and changing habits around dieting behaviour can be a way to help consumers to consume more healthy products and to control their weight. Previous studies suggested that implementation intentions - deliberate plans on when, where and how - increase the likelihood that consumers perform the intended behaviour (Armitage, 2004; Gollwitzer & Sheeran, 2006; Jackson et al., 2005). This study investigated the effect of forming implementation intentions on compliance to a regimen based on a range of meal-replacement food products and snacks. Participants (n = 57) were allocated to one of two groups, either: (1) an implementation-intention group, who formed deliberate plans (implementation intentions) to consume the products - these implementation intentions were formed only once at the beginning of the study -, or (2) a control group who formed no implementation intentions. Participants were then instructed to follow a daily regimen, which included the consumption of foods from a range of meal-replacement products and snacks provided gratis for four weeks. Results showed that the implementation-intention group consumed significantly more meal-replacement food products per week (p intentions was apparent for 18 days. These findings indicate that forming implementation intentions may assist individuals in their compliance to a meal-replacement product regimen. PMID:20883734

    Full Text Available Background. Recent studies confirmed cardioprotective role of intravenous magnesium for the prevention of cardiac events, but effect of dietary intake of this mineral via recommended dietary regimens on control and inhibition of coronary artery disease (CAD risk factors has been questioned. The aim of the present study was to determine effect of Mediterranean dietary approach on serum magnesium concentration among Iranian patients with CAD. Method. Baseline characteristics and clinical data of 102 consecutive patients with the diagnosis of CAD and candidates for isolated coronary artery bypass surgery were entered into the study. Laboratory parameters especially serum magnesium concentration were measured after 12–14 h of overnight fasting and before operation. Nutritional status was assessed by food frequency questionnaire and the diet score was calculated on the basis of Mediterranean diet quality index (Med-DQI. Results. No significant differences were found in the concentrations of albumin, last fasting blood sugar, last creatinine, and lipid profiles between the groups with Mediterranean dietary score < 5 and the group with higher dietary score; however, serum magnesium concentration in the first group was higher than that in the group with higher dietary score. Linear multivariate regression analysis showed that the lower Mediterranean dietary score was a predictor for serum magnesium concentration after adjusting for confounders. Conclusion. Taking Mediterranean dietary regimen can be associated with increased level of serum magnesium concentration, and thus this regimen can be cardioprotective because of its effects on serum magnesium.

    Background Fluoroquinolone is recommended as a pivotal antituberculous agent for treating multi-drug-resistant pulmonary tuberculosis. However, its effectiveness as first-line treatment remains controversial. The present study was conducted to validate the fluoroquinolone-containing regimen for drug-sensitive pulmonary tuberculosis. Methods We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials until June 5, 2015. Randomized controlled trials (RCTs) that compared antituberculous regimens containing fluoroquinolone with the standard regimen were included. Results Eleven RCTs that included 6,334 patients were selected. Fluoroquinolone-containing regimens had a higher rate of sputum culture conversion at 2 months of treatment (M-H fixed odds ratio [OR], 1.36; 95% confidence interval [CI], 1.20–1.54). However, the outcomes were less favorable (M-H fixed OR, 0.69; 95% CI, 0.59–0.82) and the associated total adverse events were more frequent (M-H fixed OR, 1.84; 95% CI, 1.46–2.31) in the fluoroquinolone-containing regimen group, without a significant heterogeneity according to treatment duration. Treatment with the fluoroquinolone-containing regimen for 4 months showed a higher relapse rate. Conclusions Despite a higher culture conversion rate at 2 months of treatment, the fluoroquinolone-containing regimen had limitations, including less favorable outcomes and more adverse events, as the first-line therapy for drug-sensitive pulmonary tuberculosis.

    Full Text Available Abstract Background Data regarding CD4+ recovery after switching from protease inhibitor (PI-based regimens to regimens not containing PI are scarce. Methods Subjects with virological success on first-PI-regimens who switched to NNRTI therapy (NNRTI group or to nucleoside reverse transcriptase (NRTI-only (NRTI group were studied. The effect of the switch on the ongoing CD4+ trend was assessed by two-phase linear regression (TPLR, allowing us to evaluate whether a change in the CD4+ trend (hinge occurred and the time of its occurrence. Furthermore, we described the evolution of the frequencies in CD4-count classes across four relevant time-points (baseline, before and immediately after the switch, and last visit. Finally, we explored whether the CD4+ counts evolved differently in patients who switched to NNRTI or NRTI-only regimens by considering: the overall CD4+ trends, the time to CD4+≥ 500/mm3 after the switch, and the area-under-the-curve (AUC of the CD4+ after the switch. Results Eight hundred and ninety-six patients, followed for a median of 2,121 days, were included. At TPLR, hinges occurred in 581/844 (68.9%, but in only 40/581 (6.9% within a time interval (180 days compatible with a possible relationship to the switch; furthermore, in 19/40 cases, CD4+ counts appeared to decrease after the hinges. In comparison with the NNRTI group, the NRTI group showed CD4+ count greater at baseline (P = 0.0234 and before the switch (P ≤ 0.0001, superior CD4+ T-cell increases after HAART was started, lower probability of not achieving CD4+ ≥ 500/mm3 (P = 0.0024, and, finally, no significant differences in the CD4+ T-cell AUC after the switch after adjusting for possible confounders (propensity score and pre-switch AUC. Persistence at CD4+ 3 was observed in 34/435 (7.5% patients, and a decrease below this level was found in only 10/259 (3.9% with baseline CD4+ ≥ 350/mm3.

    Gwenan M Knight

    Full Text Available A 4-month first-line treatment regimen for tuberculosis disease (TB is expected to have a direct impact on patient outcomes and societal costs, as well as an indirect impact on Mycobacterium tuberculosis transmission. We aimed to estimate this combined impact in a high TB-burden country: South Africa.An individual based M. tb transmission model was fitted to the TB burden of South Africa using a standard TB natural history framework. We measured the impact on TB burden from 2015-2035 of introduction of a non-inferior 4-month regimen replacing the standard 6-month regimen as first-line therapy. Impact was measured with respect to three separate baselines (Guidelines, Policy and Current, reflecting differences in adherence to TB and HIV treatment guidelines. Further scenario analyses considered the variation in treatment-related parameters and resistance levels. Impact was measured in terms of differences in TB burden and Disability Adjusted Life Years (DALYs averted. We also examined the highest cost at which the new regimen would be cost-effective for several willingness-to-pay thresholds.It was estimated that a 4-month regimen would avert less than 1% of the predicted 6 million person years with TB disease in South Africa between 2015 and 2035. A similarly small impact was seen on deaths and DALYs averted. Despite this small impact, with the health systems and patient cost savings from regimen shortening, the 4-month regimen could be cost-effective at $436 [NA, 5983] (mean [range] per month at a willingness-to-pay threshold of one GDP per capita ($6,618.The introduction of a non-inferior 4-month first-line TB regimen into South Africa would have little impact on the TB burden. However, under several scenarios, it is likely that the averted societal costs would make such a regimen cost-effective in South Africa.

    This study compared the efficacies of two N-methylglucomine antimoniate (MA) dose regimens for treating macaques with Leishmania braziliensis-induced chronic skin disease. Whereas all animals treated with the full dose (20 mg MA/kg/day) were cured, 50% of the monkeys receiving a low-dose regimen (5 mg MA/kg/day) relapsed. The antimony concentrations in macaque plasma and tissue samples were greater in the full-dose group than in that receiving a subtherapeutic MA regimen. Our data also suggest the presence of drug-induced hepatic pathology. PMID:19822700

  15. Total body irradiation, busulfan and cyclophosphamide as a conditioning regimen for allogeneic bone marrow transplantation for patients with hematological malignancies

    International Nuclear Information System (INIS)

    Between May 1989 and October 1998, 44 patients with hematological malignancies received allogeneic bone marrow transplantation from HLA-matched related (n=25), unrelated (n=16) or 1 locus HLA-mismatched related donors (n=3). Busulfan (BU) (8 mg/kg) and cyclophosphamide (CY) (90 mg/kg) with fractionated total body irradiation (TBI) (12 Gy) (n=30) or BU (16 mg/kg) and CY (120 mg/kg) (n=14) were given as conditioning regimen. All patients receiving BU/CY were transplanted from related donors in first remission of acute leukemia or in first chronic phase of CML (standard risk group; S-group). For 30 patients receiving TBI/BU/CY, 13 were transplanted in standard risk and 17 were in advanced stage of hematological malignancies (high risk group; H-group); 7 in S-group and 9 in H-group transplanted from unrelated donor. Severe regimen-related toxicity was found in 10% of patients receiving TBI/BU/CY (one in standard risk group and 2 in high risk group), but not found in patients receiving BU/CY. Probability of disease free survival (DFS) at 5 years was 38% in patients receiving BU/CY, and 43% in patients receiving TBI/BU/CY (52% in S-group and 35% in H-group). For patients transplanted from related donor at standard risk, probability of DFS was higher in patients receiving TBI/BU/CY than in patients receiving BU/CY (83% vs 38%; p<0.05). For patients receiving TBI/BU/CY as preparatory regimen, probability of DFS was higher in patients transplanted from related donors than in patients transplanted from unrelated donors (63% vs 29%; p<0.05), that was due to lower rate of non-relapse mortality (8% vs 61%; p<0.001). Probability or relapse was 33% in patients receiving BU/CY, and 28% in patients receiving TBI/BU/CY (23%, in S-group and 31% even in H-group), and no significant difference was found between the three groups. We conclude that this TBI/BU/CY regimen is well tolerated and is very effective in reducing relapse and improving survival, especially in standard risk

    Full Text Available Introduction: Rilpivirine (RPV is a new once-daily, non-nucleoside, reverse transcriptase inhibitor (NNRTI. In treatment-naïve patients, RPV has shown non-inferior antiviral activity to efavirenz but data in treatment-experienced patients are more limited. We assessed the efficacy and safety of RPV in treatment-experienced patients switching to a RPV-based regimen. Methods: Between September 2012 and June 2013, all antiretroviral therapy (ART experienced HIV-1 infected patients with a plasma HIV-RNA level <50 cp/mL, and switching to a RPV-based regimen, were enrolled in this prospective monocentric cohort study. Clinical and laboratory data were collected every 3 months to assess safety and efficacy. The primary endpoint was the proportion of patients with virologic success (HIV-RNA load <50 cp/mL at 12 months using the FDA snapshot algorithm. Results: A total of 281 patients (76% male, median age: 47 years, 56% MSM were enrolled in this study. Median lymphocyte CD4 count at baseline was 640/mm3. Patients have received ART for a median of 7 years and viral replication was fully suppressed for a median of 3 years. Before the switch, 39% patients were treated with NNRTI, 52% with protease inhibitor and 7% with integrase inhibitor-based regimens. Reasons for switch were simplification (176 cases, adverse events (AEs (93 cases and others (12 cases. At month 12 (database frozen on June 2014 in the snapshot analysis, 56% of patients met virologic success, 5% experienced virologic failure (n=14 and 39% had no data in the window period. In the LOCF analysis (using data from the previous available visit before month 12, 89% patients were suppressed, 5% had virologic failure and 6% had no data. Genotypic resistance analysis was performed in 7/14 patients at the time of virologic failure (3 of whom had previous NRTI/NNRTI resistance-associated mutations (RAMs, and new NNRTI and NRTI RAMs emerged in 4 patients. RPV-based regimen was generally well

    Full Text Available Background: The complexity of a medication regimen is related to the multiple characteristics of the prescribed regimen and can negatively influence the health outcomes of patients. Objective: To propose cut-off points in the complexity of pharmacotherapy to distinguish between patients with low and high complexities seen in a primary health care (PHC setting to enable prioritization of patient management. Methods: This is a cross-sectional study, which included 517 adult and elderly patients, analyzing different cut-off points to define the strata of low and high pharmacotherapy complexities based on percentiles of the population evaluated. Data collection began with the solicitation of prescriptions, followed by a questionnaire that was administered by an interviewer. The complexity of a medication regimen was estimated from the Medication Regimen Complexity Index (MRCI. High complexity pharmacotherapy scores were analyzed from patient profiles, the use of health services, and pharmacotherapy. The criteria for subject inclusion in the sample population were as follows: inhabitant of the area covered by the municipality, 18 years or older, and being prescribed at least one drug during the collection period. Exclusion criteria at the time of collection were the use of any medication whose prescription was not available. All medications were accessed through the Primary Healthcare Service (PHS. Results: The median total pharmacotherapy complexity score was 8.5. High MRCI scores were correlated with age, medications taken with in the Brazilian PHS, having at least one potential drug-related problem, receiving up to eight years of schooling, number of medications and polypharmacy (five or more medicines, number of medical conditions, number of medical appointments, and number of cardiovascular diseases and endocrine metabolic diseases. We suggest different complexity tracks according to age (e.g., adult or elderly that consider the pharmacotherapy

Via the telephone interview questions, patients were required to provide information about persistence to insulin treatment, self-reported blood glucose values, and side effects; data on demographics and diabetes characteristics were obtained from medical records.Results: Self-reported treatment withdrawal occurred in 20.1% patients, while 20.3% patients were nonadherent to daily insulin. Negative beliefs about insulin therapy (24.1% and forgetting injections (40.9% were the most common reasons for treatment withdrawal and dose skipping, respectively. Younger age (49.5±15.0 vs 56.4±12.0 years (P=0.001 and shorter duration of diabetes (4.8±4.3 vs 8.8±6.3 years (P=0.0008 and treatment duration (5.2±2.4 vs 10.7±2.4 months (P=0.0001 were noted, respectively, in discontinuers vs continuers. Basal bolus was the most commonly prescribed insulin regimen (51.0%, while associated with higher likelihood of skipping a dose than regular use (61.3% vs. 46.0%, P=0.04.Conclusions: Persistence to insulin therapy was poorer than anticipated but appeared to be higher in patients with the basal bolus regimen. Negative perceptions about insulin therapy seemed to be the main cause for poor adherence in our cohort.Keywords: type 2 diabetes, insulin treatment adherence

    Full Text Available This study was aimed to determine peculiarities in regimens of the pump insulin therapy and to reveal the optimal basal-to-bolus insulin ratio that are necessary for achieving optimal glycemic control in adoles-cents with type 1 diabetes mellitus (T1DM.  82 adolescents at the age of 14–18 with T1DM, using continuous subcutaneous insulin infusion (CSII from 5 months to 7.5 years were monitored with continuous glucose monitoring (CGM system «Guar-dian Real Time» or CGM system, built in MiniMed Paradigm Revel System 722 (Medtronic Minimed, USA. Assessing the quality of glycaemic control was based on the level of glycated haemoglobin (HbA1c. The results of CGM were reviewed and average for 3 days performances: total daily dose of insulin, dose of basal and bolus insulin, basal-to-bolus insulin ratio, carbohydrate content of the meal, expressed in BE, carbohydrate ratio, insulin sensitivity factor were determined. The patients were subdivided into 2 groups: group 1 – adolescents with the optimal/suboptimal glycemic control (n = 55, 2 – adolescents with long-standing poorly controlled T1DM (n = 27. Average total daily dose of basal insulin (U in a day, U per kg in a day in adolescents group 1 was significantly higher, com-pared with patients in group 2 (р = 0.043; р = 0.038 respectively. Patients in group 2 received more car-bohydrates with a meal intake and had higher doses of average total daily bolus insulin. The average ba-sal-to-bolus ratio from group 1 patients was 51/49%, compared with group 2 patients – 45/55% (р = 0.026.  An important condition for achieving optimal glycemic control is a high level of compliance and skills of adolescents. Optimal well-balanced basal-to-bolus insulin ratio in adolescents with T1DM on CSII, which can provide improvements in blood glucose management and reducing the risk of complications of the disease, is 51/49%.

This regimen also seems to be feasible in elderly people. Although high response rates and prolonged response duration indicate the potential efficacy of this treatment, our results should be interpreted cautiously because of the small number of patients involved. Capecitabine was most effective in the pancreatic subgroup, which would seem to be more sensitive to chemotherapy.Keywords: capecitabine, gastroenteropancreatic neuroendocrine tumors, metronomic chemotherapy

    The objective of the study was to assess the post-weaning growth response of Sahiwal calves reared on four different pre-weaning dietary regimens. The four diets were: (a) whole cow's milk, starter ration (SR; CP = 20%, total digestible nutrients (TDN) = 72%) and Berseem hay (H; Egyptian clover; CP = 21%, TDN = 63%); (b) whole cow's milk + H; (c) milk replacer (MR; reconstituted to supplier specification; Sprayfo®) + SR + H; and (d) MR + H. The protein and fat percentages of reconstituted MR were 2.22 and 1.84, respectively. Milk or MR were fed at the rate of 10% of the calves' body weight (BW) until 56 days of age, and then withdrawn gradually until weaned completely by 84 days of age. The average initial BW of calves in groups A, B, C and D were 56.3 ± 1.0, 47.5 ± 1.0, 40.4 ± 1.0 and 30.3 ± 1.0 kg, respectively. Initially, there were 12 calves in each group with six of each sex; however, one male calf died from each of groups B and C and were not replaced. During the post-weaning period, 13 to 24 weeks, the calves were fed a single total mixed ration ad libitum based on maize, canola meal, wheat straw and molasses containing 16% CP and 70% TDN. Daily feed intake and weekly BW gains were recorded. The data were analyzed by MIXED model analysis procedures using the statistical program SAS. The intake of calves as percent of their BW, feed conversion ratio and cost per kg of BW gain were not different (P > 0.05) across treatments. The daily gain at 24 weeks of age for the pre-weaning treatments A, B, C and D were 746 ± 33, 660 ± 33, 654 ± 33 and 527 ± 33 g/day and the final liveweights of calves were 119 ± 4.2, 102 ± 4.2, 95 ± 4.2 and 75 ± 4.2 kg, respectively. Gains were influenced significantly (P calves fed MR and H only during the pre-weaning period were unable to catch up post weaning with calves on other dietary treatments. The calves fed whole milk from birth at the rate of 10% of liveweight together with concentrates had higher weaning weight

However, there is no clear evidence to date about which chemotherapy regimen should be the proper initial treatment of indolent lymphoma. More recently, the use of fludarabine has raised concerns due to its high number of toxicities, especially hematological toxicity and infectious complications. The present study aimed to retrospectively evaluate both the efficacy and the potential toxicities of the two main regimens (fludarabine-based and CHOP-like regimens in patients with previously untreated indolent lymphoma. Among a total of 107 patients assessed, 54 patients received fludarabine-based regimens (FLU arm and 53 received CHOP or CHOPE (doxorubicin, cyclophosphamide, vincristine, prednisone, or plus etoposide regimens (CHOP arm. The results demonstrated that fludarabine-based regimens could induce significantly improved progression-free survival (PFS compared with CHOP-like regimens. However, the FLU arm showed overall survival, complete response, and overall response rates similar to those of the CHOP arm.

    Background. The regimen of linezolid and moxifloxacin was found to be efficacious in the hollow fiber system model of pediatric intracellular tuberculosis. However, its kill rate was slower than the standard 3-drug regimen of isoniazid, rifampin, and pyrazinamide. We wanted to examine the effect of adding a third oral agent, faropenem, to this dual combination. Methods. We performed a series of studies in the hollow fiber system model of intracellular Mycobacterium tuberculosis, by mimicking pediatric pharmacokinetics of each antibiotic. First, we varied the percentage of time that faropenem persisted above minimum inhibitory concentration (TMIC) on the moxifloxacin-linezolid regimen. After choosing the best faropenem exposure, we performed experiments in which we varied the moxifloxacin and linezolid doses in the triple regimen. Finally, we performed longer-duration therapy validation experiments. Bacterial burden was quantified using both colony-forming units per milliliter (CFU/mL) and time to positivity (TTP). Kill slopes were modeled using exponential regression. Results. TTP was a more sensitive measure of bacterial burden than CFU/mL. A faropenem TMIC > 62% was associated with steepest microbial kill slope. Regimens of standard linezolid and moxifloxacin plus faropenem TMIC > 60%, as well as higher-dose moxifloxacin, achieved slopes equivalent to those of the standard regimen based by both TTP and CFU/mL over 28 days of treatment. Conclusions. We have developed an oral faropenem-linezolid-moxifloxacin (FLAME) regimen that is free of first-line drugs. The regimen could be effective against both multidrug-resistant and drug-susceptible tuberculosis in children. PMID:27742640

  16. Modified Folfox regimen combined with interventional therapy for the treatment of advanced gastric cancer: a clinical study

    International Nuclear Information System (INIS)

    Objective: To evaluate the efficacy and safety of modified Folfox regimen in combination with interventional therapy for patients with advanced gastric cancer. Methods: Thirty-four patients were treated with modified Folfox regimen in combination with interventional therapy which was given at intervals of 4 or 5 weeks until the disease became worse, or the patient could not tolerate the drug toxicity, or the patient decided to stop the treatment. On an average,each patient received 7 therapeutic courses. Response to treatment and toxicity reaction to the drug were recorded according to NCI toxicity criteria. All data were analyzed by using Kaplan-Meier method with SPSS software(version 15.0, Chicago, IL, USA). Results: All patients tolerated the toxicity and treatment. The mean follow-up period was 17 months, with the longest period being of 32 months. Of 34 patients, complete remission was seen in 4(11.8%), partial remission in 20(58.8%), stable condition in 6(17.6%) and deterioration in 4(11.8%). The overall response rate was 70.6%. The cumulated survival rate at 12, 24 and 32 months was 76.5%, 33.1% and 12.5% respectively, with a median survival time of 18 months. NCI grade 1 or 2 toxicities occurred, including alopecia (64.7%), peripheral neuritis (11.8%), anemia (11.8%), leucopenia(31.9%), diarrhea (29.4%), stomatitis (23.5%), thrombocytopenia (11.8%) and elevated ALT(5.9%). Grade 3 or 4 occurred in 47.1% and 11.8% of patients respectively,which included nausea, vomiting and diarrhea. Four patients developed grade 3 ALT elevation. No treatment-related death occurred. Conclusion: Modified Folfox regimen in combination with interventional therapy is a safe and effective treatment for advanced gastric cancer with fewer adverse effects. (authors)

    Full Text Available We combined the outcomes of all randomised controlled trials to investigate the safety and efficacy of steroid avoidance or withdrawal (SAW regimens in paediatric kidney transplantation compared with steroid-based (SB regimens.A systematic literature search of PubMed, Embase, Cochrane Library, the trials registry and BIOSIS previews was performed. A change in the height standardised Z-score from baseline (ΔHSDS and acute rejection were the primary endpoints.Eight reports from 5 randomised controlled trials were included, with a total of 528 patients. Sufficient evidence of a significant increase in the ΔHSDS was observed in the SAW group (mean difference (MD = 0.38, 95% confidence interval (CI 0.07-0.68, P = 0.01, particularly within the first year post-withdrawal (MD = 0.22, 95% CI 0.10-0.35, P = 0.0003 and in the prepubertal recipients (MD = 0.60, 95% CI 0.21-0.98, P = 0.002. There was no significant difference in the risk of acute rejection between the groups (relative risk = 1.04, 95% CI 0.80-1.36, P = 0.77.The SAW regimen is justified in select paediatric renal allograft recipients because it provides significant benefits in post-transplant growth within the first year post-withdrawal with minimal effects on the risk of acute rejection, graft function, and graft and patient survival within 3 years post-withdrawal. These select paediatric recipients should have the following characteristics: prepubertal; Caucasian; with primary disease not related to immunological factors; de novo kidney transplant recipient; with low panel reactive antibody.

    Full Text Available Background and Objectives: The present study aimed to evaluate the effect of classical and azithromycin-containing triple therapy eradication regimen against H. Pylori in children, and to determine the level of patients’ tolerance. Patients and Methods: This single clinical trial was performed in 2014 on 2 to 15 years old children. All children, in whom H. Pylori infection was confirmed through multiple biopsies of the stomach and required treatment, were enrolled in the study. H. Pylori-positive patients were treated alternately with two different drug regimens; Group OCA received clarithromycin 7.5 mg/kg/day every 12 hours for 10 days, amoxicillin 50 mg/kg/day every 12 hours for 10 days, and omeprazole 1 mg/kg/day every 12 hours for two weeks, and Group OAA received azithromycin 10 mg/kg/day once a day (before meal for 6 days along with amoxicillin and omeprazole. Four to six weeks after completion of treatment, patients’ stool was tested for H. Pylori through the monoclonal method using the Helicobacter antigen quick kit. Results: There were no significant differences between the two groups regarding gender and age of patients. Based on ITT analysis, the therapeutic response in the OAA and OCA groups were 56.2% and 62.5%, respectively (P = 0.40. Drug adverse effects were 15.6% in the OCA and 3.1% in the OAA group (P = 0.19. Conclusions: The therapeutic response was seen in more than half of the patients treated with triple therapy of H. Pylori eradication regimen including azithromycin or clarithromycin, and there was no significant difference between the two treatment groups.

    Objectives To determine whether an individualised hydration regimen reduces thermal, physiological and perceptual strain during match-play tennis in the heat, and minimises alterations in neuromuscular function and physical performance postmatch and into recovery. Methods 10 men undertook two matches for an effective playing time (ball in play) of 20 min (∼113 min) in ∼37°C and ∼33% RH conditions. Participants consumed fluids ad libitum during the first match (HOT) and followed a hydration regimen (HYD) in the second match based on undertaking play euhydrated, standardising sodium intake and minimising body mass losses. Results HYD improved prematch urine specific gravity (1.013±0.006 vs 1.021±0.009 g/mL; p<0.05). Body mass losses (∼0.3%), fluid intake (∼2 L/h) and sweat rates (∼1.6 L/h) were similar between conditions. Core temperature was higher during the first 10 min of effective play in HOT (p<0.05), but increased similarly (∼39.3°C) on match completion. Heart rate was higher (∼11 bpm) throughout HOT (p<0.001). Thermal sensation was higher during the first 7.5 min of effective play in HOT (p<0.05). Postmatch knee extensor and plantar flexor strength losses, along with reductions in 15 m sprint time and repeated-sprint ability (p<0.05), were similar in both conditions, and were restored within 24 h. Conclusions Both the hydration regimen and ad libitum fluid consumption allowed for minimal body mass losses (<1%). However, undertaking match-play in a euhydrated state attenuated thermal, physiological and perceptual strain. Maximal voluntary strength in the lower limbs and repeated-sprint ability deteriorated similarly in both conditions, but were restored within 24 h. PMID:24668383

    Cetuximab is a human-murine chimeric monoclonal antibody to the epidermal growth factor receptor, active for advanced colorectal cancer treatment in combination with chemotherapy. Cetuximab mainly acts by inhibiting epidermal growth factor receptor-mediated pathways in cancer cells; however, in the human host, its IgG1 backbone may offer additional antitumor activity that includes FcγRs-mediated antibody-dependent cell cytotoxicity, phagocytosis, cross priming, and tumor-specific T-cell-mediated immune response. These mechanisms are still under active investigation. At this purpose, we have performed an immunologic investigation in advanced colon cancer patients enrolled in an ongoing phase II trial aimed to test the toxicity and the biological and antitumor activity of a novel biochemotherapy regimen combining polychemotherapy with gemcitabine, irinotecan, levofolinic acid, and fluorouracil with cetuximab and with subcutaneous low-dose metronomic aldesleukin (GILFICet regimen). The peripheral blood mononuclear cells of the first 20 patients enrolled in the GILFICet trial were collected at baseline and after 6 treatment cycles and examined for immune-phenotype change by flow cytometry. Colon cancer-specific T-cell lines were also generated ex vivo from these samples and subsequently characterized for immune phenotype, functional activity, and antigen specificity. We found a treatment-related increase of circulating dendritic cells, natural killer cells, central memory T cells, and activated T cells with a T-helper 1 (Th1)-cytotoxic phenotype. In addition, the ex-vivo characterization of antigen-specific T cells derived from the treated patients revealed a significant increase in proliferating cytotoxic T-lymphocyte precursors specific for carcinoembryonic antigen and thymidylate synthase derivative epitope peptides. On these basis, we concluded that the GILFICet regimen exerts substantial immune-modulating activity that significantly affects tumor antigen

    Full Text Available Background Pre-eclampsia and the subsequent eclampsia account for a common cause of maternal mortality worldwide and efforts aimed at reducing its menace are vital. Objective To estimate the serum magnesium levels in pre-eclampsia and eclampsia and to study the effect of using different regimens of magnesium sulphate. Methods 70 cases of pre-eclampsia and eclampsia and 35 normal pregnant women as controls were studied. Serum magnesium levels were estimated using Atomic Absorption Spectrophotometer (Model AAS-4139 at baseline and at frequent intervals during gestation and the overall parameters were meticulously observed. Results Majority (60% of studied cases was nullipara with gestation age of 36-40 weeks. Statistically significant reduction of mean diastolic blood pressure and protein-urea was observed after using both intramuscular and intravenous regimens of magnesium sulphate. Mean initial serum magnesium level (mg/dl±SD was 1.81±0.58 in group A,1.55±0.41 in group B and 1.49±0.41 in group C. Mean serum magnesium levels during first 4 hours after therapy were statistically significant between intramuscular and intravenous regimen groups while same were statistically insignificant at 8,12,16,24 and 32 hours. Besides, few minor side effects including headache, vomiting, reduced tendon reflexes and thrombocytopenia, no severe side effects and no maternal mortality were seen. Conclusion Hypomagnesemia occurs during states of preeclampsia and eclampsia, and, administration of magnesium sulphate is effective and safe in preventing maternal mortality.

    In preclinical testing of antituberculosis drugs, laboratory-adapted strains of Mycobacterium tuberculosis are usually used both for in vitro and in vivo studies. However, it is unknown whether the heterogeneity of M. tuberculosis stocks used by various laboratories can result in different outcomes in tests of antituberculosis drug regimens in animal infection models. In head-to-head studies, we investigated whether bactericidal efficacy results in BALB/c mice infected by inhalation with the laboratory-adapted strains H37Rv and Erdman differ from each other and from those obtained with clinical tuberculosis strains. Treatment of mice consisted of dual and triple drug combinations of isoniazid (H), rifampin (R), and pyrazinamide (Z). The results showed that not all strains gave the same in vivo efficacy results for the drug combinations tested. Moreover, the ranking of HRZ and RZ efficacy results was not the same for the two H37Rv strains evaluated. The magnitude of this strain difference also varied between experiments, emphasizing the risk of drawing firm conclusions for human trials based on single animal studies. The results also confirmed that the antagonism seen within the standard HRZ regimen by some investigators appears to be an M. tuberculosis strain-specific phenomenon. In conclusion, the specific identity of M. tuberculosis strain used was found to be an important variable that can change the apparent outcome of in vivo efficacy studies in mice. We highly recommend confirmation of efficacy results in late preclinical testing against a different M. tuberculosis strain than the one used in the initial mouse efficacy study, thereby increasing confidence to advance potent drug regimens to clinical trials.

    Coronary artery disease (CAD) is a major cause of mortality internationally and in Pakistan. Angioplasty has been proven to be an effective treatment for CAD. Stent thrombosis is a known but preventable complication of angioplasty. Several factors may lead to stent thrombosis with non-compliance with the prescribed drug regimen, being one of the most important factors. We report a case of stent thrombosis after four months of angioplasty. After exploring of patient's post angioplasty routines, it was found that the patient was non-compliant with the prescribed anti- platelets and other prescribed drugs. This time the patient presented with another acute myocardial infarction, and he went through angioplasty again.

    Full Text Available The life-long antiretroviral treatment of HIV-1 infection requires effective and well tolerated medications complemented by high rates of adherence in order to achieve viral suppression, immunologic reconstitution and to prevent the development of resistance. Single-tablet regimens (STRs, combining a full antiretroviral regimen in one tablet taken once daily, have been designed to achieve high adherence and better long-term outcomes. “STRike” is the first cohort study, describing the use of various STRs in routine clinical practice in Germany. In this observational cohort study 800 participants will be included in 4 treatment arms, treated with the STRs of TDF/FTC/EFV (a retrospective and prospective arm, TDF/FTC/RPV or TDF/FTC/COBI/EVG after regulatory approval. Patients are followed for at least two years, and reasons for choice of medications and treatment satisfaction will be collected, in addition to safety, demographic, effectiveness data. To date 344 patients on TDF/FTC/EFV and 123 patients on TDF/FTC/RPV are being followed. In general, the spectrum of patients in the study reflects the German HIV-1 infected population with regards to gender (88%/89% male, age (median 40/38 years of age and mode of infection (71%/63% MSM. However, patients starting TDF/FTC/RPV are less progressed in their disease according to their CDC stage compared with patients on TDF/FTC/EFV (74.5% stage “A” vs. 53.2%. Patients starting TDF/FTC/RPV show less comorbidities (54% vs. 82% with a spectrum different from patients on TDF/FTC/EFV. Pre-existing neuropsychiatric comorbidities are relatively more common (10% more among patients starting TDF/FTC/RPV than TDF/FTC/EFV. The decision to use an STR is mostly driven by patient preference to start with a more convenient ART regimen (56% or to simplify their current ART regimen (75%. STRs aim to make treatment of HIV more convenient, more efficacious and more durable and by that allowing for earlier initiation of

    Full Text Available Introduction: The long-term effects of an intensified induction regimen are unknown. In this pilot, randomized, prospective study we evaluate the effect of a short-term four-drugs induction regimen in patients with high baseline viral load. Methods: Naive patients with HIV-RNA>100.000 copies/ml receiving TDF+FTC+EFV+RAL (group ER for 4 months and were then simplified to TDF+FTC+EFV. Two randomized control groups treated ab-initio with TDF+FTC+EFV (E or TDF+FTC+RAL (R were used. Results: 19 patients with a mean age of 38 years and mean baseline CD4 count of 334 (SD 216 cells/mcL and HIV-RNA of 5.47 log (SD 0.32 copies/mL were enrolled. No baseline significant difference was observed among groups. Early HIV-RNA reduction was significantly higher in ER compared to the other groups from week 1 to week 4 (P from 0.026 to 0.003 (figure 1, thereafter HIV-RNA values were comparable among the groups. At week 96, all patients had an HIV-RNA < 50 copies/mL, however only patients in the ER group had in all cases an HIV-RNA level < 3 copies/mL with a statistically significant difference compared to E (60%; P=0.038 and R (50%; P=0.020. At 96 weeks, CD4 cell median counts were 765 cells/mcL for ER, 600 cells/mcL for E and 771 for R (P=0.16, however patients in the ER group presented a lower proportion of activated CD4+CD38+HLADR+ cells (1.9% versus 3.9 and 3.8% and CD8+CD38+HLADR+ cells (10.3% versus 16.8 and 16.5% and a significantly better CD4/CD8 ratio (0.98 versus 0.53 and 0.61; P=0.03. Conclusions: A four-drug regimen in naive patients with high pre-therapy viral load improves early virologic response. A quick drop of HIV-RNA seems to correlate with a sustained virologic response. Although limited in time (four months, the four-drug regimens correlates with an improved immunological response as measured by the CD4/CD8 ratio or the percentage of activated CD4+ and CD8+ cells. The reasons why this happens deserve further studies. This study highlights the

    This study sought to determine the completeness and congruence of records for drugs ordered and received by outpatients. The setting was a large outpatient medical facility that was part of a large multispecialty hospital. It was found that a listing of current drugs orders (prepared by physicians) and a listing of current prescription drugs consumed (prepared from pharmacy drug profiles) each agreed 73 per cent of the time with a list of 107 prescription drugs actually consumed by 26 study patients. Lists were compared based on drug name, strength and directions for use. Further, the physician and pharmacy lists correlated with one another 70 per cent of the time, indicating a substantial degree of inconsistent as well as incomplete drug records within the same setting. In another comparison involving medical chart drug notations and pharmacy drug profiles, a complete match or drug name, strength and directions for use occurred in 39 per cent of the cases, while a match on drug name only occurred 64 per cent of the time. The highest degree of congruence occurred between hospital discharge medication notes and outpatient drug profile records. Based on the results of this study, the common assumption that drug records in such settings are congruent and complete appears unwarranted. PMID:7266115

    Full Text Available Abstract Objective The objective of this work was to study the virological outcomes associated with two different types of treatment interruption strategies in patients with allergic reactions to nevirapine (NVP. We compared the virological outcomes of (1 HIV-1-infected patients who discontinued an initial NVP-based regimen because of cutaneous allergic reactions to NVP; different types of interruption strategies were used, and second-line regimen was based on efavirenz (EFV; and (2 HIV-1-infected patients who began an EFV-based regimen as a first-line therapy (controls. Methods This retrospective cohort included patients who began an EFV-based regimen, between January 2002 and December 2008, as either an initial regimen or as a subsequent regimen after resolving a cutaneous allergic reaction against an initial NVP-based regimen. The study ended in March 2010. The primary outcome was virological failure, which was defined as either (a two consecutive plasma HIV-1 RNA levels >400 copies/mL or (b a plasma HIV-1 RNA level >1,000 copies/mL plus any genotypic resistance mutation. Results A total of 559 patients were stratified into three groups: (a Simultaneous Interruption, in which the subjects simultaneously discontinued all the drugs in an NVP-based regimen following an allergic reaction (n=161; (b Staggered Interruption, in which the subjects discontinued NVP treatment while continuing nucleoside reverse transcriptase inhibitor (NRTI backbone therapy for a median of 7 days (n=82; and (c Control, in which the subjects were naïve to antiretroviral therapy (n=316.

    Purpose: To retrospectively assess the influence of prophylactic cranial irradiation (PCI) timing on brain relapse rates in patients treated with two different chemoradiotherapy (CRT) regimens for Stage IIIB non-small-cell lung cancer (NSCLC). Methods and Materials: A cohort of 134 patients, with Stage IIIB NSCLC in recursive partitioning analysis Group 1, was treated with PCI (30 Gy at 2 Gy/fr) following one of two CRT regimens. Regimen 1 (n = 58) consisted of three cycles of induction chemotherapy (ICT) followed by concurrent CRT (C-CRT). Regimen 2 (n = 76) consisted of immediate C-CRT during thoracic radiotherapy. Results: At a median follow-up of 27.6 months (range, 7.2-40.4), 65 patients were alive. Median, progression-free, and brain metastasis-free survival (BMFS) times for the whole study cohort were 23.4, 15.4, and 23.0 months, respectively. Median survival time and the 3-year survival rate for regimens 1 and 2 were 19.3 vs. 26.1 months (p = 0.001) and 14.4% vs. 34.4% (p < .001), respectively. Median time from the initiation of primary treatment to PCI was 123.2 (range, 97-161) and 63.4 (range, 55-74) days for regimens 1 and 2, respectively (p < 0.001). Overall, 11 (8.2%) patients developed brain metastasis (BM) during the follow-up period: 8 (13.8%) in regimen 1 and 3 (3.9%) in regimen 2 (p = 0.03). Only 3 (2.2%) patients developed BM at the site of first failure, and for 2 of them, it was also the sole site of recurrence. Median BMFS for regimens 1 and 2 were 17.4 (13.5-21.3) vs. 26.0 (22.9-29.1 months), respectively (p < 0.001). Conclusion: These results suggest that in Stage IIIB NSCLC patients treated with PCI, lower BM incidence and longer survival rates result from immediate C-CRT rather than ITC-first regimens. This indicates the benefit of earlier PCI use without delay because of induction protocols.

    Mature B-cell non-Hodgkin lymphoma (B-NHL) comprises more than 50% of all non-Hodgkin lymphoma (NHL) in children and adolescents. Many B-NHL subtypes frequently observed in adults are rarely diagnosed in children and adolescents. In this age group, Burkitt lymphoma (BL), Burkitt leukemia or FAB L3 leukemia (B-AL), diffuse large B-cell lymphoma (DLBCL), primary mediastinal large B-cell lymphoma (PMLBL), follicular lymphoma (FL), and aggressive mature B-NHL not further classifiable (B-NHL nfc) are the most common subtypes. Diverse clinical trials demonstrated similar results of current combination chemotherapy regimens succeeding in overall survival rates of more than 80%. However, treatment-related toxicity and the poor prognosis of relapse are serious concerns. Furthermore, specific histological B-NHL subtypes are rare in children and optimal treatment is not established. New treatment modalities are urgently needed for these patient groups. Rituximab, a monoclonal antibody that is already established in the treatment of adults with mature B-NHL, demonstrated promising results in pediatric patients. The definitive role of rituximab in the treatment of children and adolescents with B-NHL needs to be evaluated in prospective controlled clinical trials. This review provides a comprehensive overview of chemotherapy regimens and the perspectives for children and adolescents with mature B-cell lymphoma and leukemia. PMID:23570584

    In order to increase the availability of adjuvant radiotherapy of breast cancer patients and make it more convenient and cheaper, in numerous cancer centres, the dose per fraction has been increased from 2 Gy to 2.25-2.75 Gy and the total dose has been decreased from 50 Gy to 40-45 Gy. The risk of developing any late complications after conventionally fractionated megavoltage radiotherapy is estimated to be below 1%. The aim of this review is to determine whether hypofractionated regimens increase the risk of damage to the brachial plexus. A review of the published literature shows that the use of doses per fraction in the range from 2.2 Gy to 4.58 Gy with the total doses between 43.5 Gy and 60 Gy causes a significant risk of brachial plexus injury which ranged from 1.7% up to 73%. The risk of radiation induced brachial plexopathy was smaller than 1% using regimens with doses per fraction between 2.2 and 2.5 Gy with the total doses between 34 and 40 Gy. Surgical manipulations in the axilla and chemotherapy have to be taken into account as additional factors which may increase the risk of brachial plexopathy.

    Full Text Available Cyclosporine A (CsA is one of the most effective systemic drugs available for the treatment of psoriasis, as evidenced by the results of several randomized studies and by a prolonged experience in dermatological setting. In clinical practice, CsA is usually used for the induction of psoriasis remission at a daily dose included in the range of 2.5–5 mg/kg and with intermittent short-term regimens, lasting on average 3–6 months. The magnitude and rapidity of response are dose dependent, as well as the risk of development of adverse events. Therefore, the dose should be tailored to patient’s needs and general characteristics and adjusted during the treatment course according to both the efficacy and tolerability. Some studies support the feasibility of pulse administration of CsA for a few days per week for both the induction and the maintenance of response in psoriasis patients. This paper will review the data on CsA regimens for plaque-type psoriasis and will focus the attention on dose, treatment duration, novel schedules, and role in combination therapies, including the association with biologicals.

    The inclusion of antithymocyte globulin (ATG) in cord blood transplantation is controversial. We evaluated outcomes according to ATG inclusion in 297 children and adolescents with acute lymphoblastic leukemia (ALL) who received myeloablative total body irradiation-based conditioning and either single-unit (74%) or double-unit (26%) grafts. Ninety-two patients (31%) received ATG and 205 (69%) did not. ATG recipients were more likely to be cytomegalovirus seronegative. The incidences of day 100 grades II to IV acute graft-versus-host disease (GVHD; 30% versus 54%, P = .0002) and chronic GVHD (22% versus 43%, P = .0008) were lower with ATG compared with non-ATG regimens. However, day 100 grades III to IV acute GVHD was comparable (11% versus 17%, P = .15). The 3-year incidences of transplant-related mortality (16% versus 17%, P = .98), relapse (17% versus 27%, P = .12), and leukemia-free survival (66% versus 55%, P = .23) in ATG and non-ATG recipients were similar. There were no differences in viral reactivation between treatment groups (60% versus 58%, P = .83). Therefore, the data suggest that incorporation of ATG with myeloablative conditioning regimens may be useful in reducing the risk of acute and chronic GVHD without any deleterious effect on transplant-related mortality, relapse, or leukemia-free survival in children and adolescents with ALL.

    An increasing number of children with non-malignant diseases can be cured by allogeneic haematopoietic stem cell transplantation (HSCT). Treosulfan (L-treitol-1,4-bis-methanesulfonate) is being used more frequently for conditioning, owing to its' lower toxicity profile compared with conventional myeloablative regimens. A retrospective analysis was performed of children registered in the EBMT database, who received treosulfan before HSCT between January 2005 and 2010, to identify possible dose-related toxicity and determine the incidence of engraftment, treatment-related mortality and overall survival (OS). Results from 316 transplants from 11 different countries are presented. Ninety-five (30%) were under 1 year of age at the time of transplant. OS was 83% and event-free survival was 76%; 3-year OS and event-free survival of infants below 1 year were 79% and 73%, respectively. No association was found with age at transplant, dose of treosulfan given, other agents used in combination with treosulfan, donor type, stem cell source, or second or subsequent transplant. In this report of the largest number of children to date receiving treosulfan for non-malignant diseases, treosulfan is shown to be a safe and effective agent even for those under 1 year of age at the time of transplant. Further prospective studies are needed using precisely defined protocols with pharmacokinetic monitoring and detailed chimerism analysis. In addition, long-term studies will be vital to determine long-term effects, for example, on fertility in comparison with other regimens.

    Hematopoietic stem cell transplantation (HSCT) is an effective treatment for patients with refractory lymphomas. Nucleoside analogs (NAs) and DNA alkylating agents are efficacious in treating hematologic malignancies. To design an efficacious and more economical pretransplant regimen for lymphoma patients, we analyzed the cytotoxicity of cladribine (Clad), gemcitabine (Gem), busulfan (Bu), and suberoylanilide hydroxamic acid (SAHA) in lymphoma cell lines. J45.01 and U937 lymphoma cell lines were exposed to drugs, alone or in combination, for 48 hours and analyzed with the MTT and annexin V assays, Western blotting, and flow cytometry. On the basis of the IC5-10 values of the drugs, the Clad+Gem+Bu combination inhibited the proliferation of both cell lines to ∼55%-60%. Addition of SAHA to this combination decreased proliferation further to ∼30%. Exposure to the Clad+Gem+Bu+SAHA combination activated the DNA damage response and ATM-CHK2 pathway; modified histones; decreased mitochondrial membrane potential, which caused leakage of apoptosis-inducing factors; and activated apoptosis. Pretreatment of cells with the pan-caspase inhibitor Z-VAD-FMK blocked the phosphorylation of histone 2AX and cleavage of PARP-1 and caspases. The Clad+Gem+Bu+SAHA combination provides synergistic cytotoxicity in lymphoma cell lines. Our results may be a basis for using this combination as a pretransplant conditioning regimen in a clinical trial for lymphoma patients undergoing hematopoietic stem cell transplantation, replacing the more expensive nucleoside analog clofarabine.

    A cluster randomised controlled trial was conducted to evaluate the effectiveness of a twice-daily moisturising regimen as compared to 'usual' skin care for reducing skin tear incidence. Aged care residents from 14 Western Australian facilities (980 beds) were invited to participate. The facilities were sorted into pairs and matched in terms of bed numbers and whether they provided high or low care. One facility from each matched pair was randomised to the intervention group. Consenting residents in an intervention facility received a twice-daily application of a commercially available, standardised pH neutral, perfume-free moisturiser on their extremities. Residents in the control facilities received ad hoc or no standardised skin-moisturising regimen. Participant numbers were sufficient to detect a 5% difference in incidence rate between the two groups with 80% power and a significance level of P = 0·05, and the inter-cluster correlation coefficient was 0·034. Data were collected over 6 months. A total of 1396 skin tears on 424 residents were recorded during the study. In the intervention group, the average monthly incidence rate was 5·76 per 1000 occupied bed days as compared to 10·57 in the control group. The application of moisturiser twice daily reduced the incidence of skin tears by almost 50% in residents living in aged care facilities.

    Full Text Available Warfarin is still the most clinically used oral anti-coagulant despite of its narrow therapeutic index and high risk of hemorrhage. The mean daily dose of warfarin varies widely from patient to patient, and to achieve the same therapeutic effect, the daily dose of warfarin could be varied over 20-fold. The variability in warfarin dosage depends on several factors, including gene polymorphisms, index of body mass, age and other drugs, and these factors compelled the clinicians to individualize warfarin dosage in order to optimize the therapeutic regimen. A number of genes are involved in metabolism of warfarin, such as cytochrome P450 2C9 (CYP2C9, vitamin K epoxide reductase complex subunit 1 (VKORC1, cytochrome P450 4F2 (CYP4F2, gamma-glutamylcarboxylase (GGCX, etc. Of them CYP2C9 and VKORC1 are the emphasis of current researches. The association between the polymorphism of CYP2C9 and VKORC1 and individualized warfarin therapeutic regimen are mainly discussed in this paper. DOI: 10.11855/j.issn.0577-7402.2015.02.16

    The aim of this study was to assess the impact of the regimen of screening on the frequency of early diagnosis and resection in two computed tomography screening programs. The stage and size distribution of all screen-diagnosed lung cancers was compared. A total of 775 patients in the International Early Lung Cancer Action Program (I-ELCAP) and 664 patients in the National Lung Screening Trial (NLST) were screen-diagnosed; that is, resulting from a positive result requiring further diagnostic workup. The frequency of stage I diagnoses, resections, tumor size, and lung cancer-specific survival were determined. Cox regression was used to identify the key determinants of lung cancer cure. The frequency of clinical stage I lung cancer in I-ELCAP was 82%, and in the NLST it was 67% (Ppathologic and clinical if not resected) was 78% in I-ELCAP and 62% in the NLST (Pdeterminants of survival, independent of age, smoking history, and tumor size. The higher frequency of stage I disease and resection and smaller tumor size resulted in a significantly higher survival rate in I-ELCAP than in the NLST. These differences strongly support the importance of a specified regimen of screening, as alternative explanations have been addressed.

    Full Text Available BACKGROUND: The knowledge-base of emerging drug resistance profiles in children exposed to abacavir-based antiretroviral regimens in South Africa is very limited. This study investigated the suitability of didanosine-based 2nd-line regimens for children in the context of antiretroviral drug resistance patterns emerging after 1st-line virologic failure. METHODS: A retrospective dataset of 354 antiretroviral drug resistant genotypes from children failing either abacavir (n = 81 or stavudine (n = 273 based 1st-line regimens, was analysed. Samples were sent to the HIV genotyping laboratory at Charlotte Maxeke Johannesburg Academic Hospital, for routine testing. Pol sequences were submitted to the Stanford HIV drug resistance database for genotypic predictions. RESULTS: Children were exposed to abacavir or stavudine-based 1st-line regimens for an average of 21 and 36 months, respectively. The frequency of reduced susceptibility to didanosine was substantial in the abacavir-exposed group (69.1%.This reduced susceptibility was commonly attributed to L74V/I (n = 44 and to a lesser extent K65R (n = 10 mutations. Didanosine resistance was observed in 43.2% of patients exposed to stavudine-based regimens. In contrast, most children remained susceptible to stavudine regardless of exposure to abacavir (77.8% or stavudine (74.7%. At least 80% of children remained susceptible to zidovudine irrespective of stavudine or abacavir-exposure. The presence of the K65R mutation was more common after abacavir pressure (12.3% vs 1.8%. CONCLUSION: Analysis revealed that didanosine-based 2nd-line regimens have limitations for South African children, given the high frequency of mutations that confer cross-resistance to didanosine; especially after abacavir-exposure. This data has influenced South African paediatric treatment guidelines, which now recommend zidovudine-based 2nd-line regimens.

    Full Text Available Abstract Background Thalidomide based regimen is an effective and well tolerated therapy in multiple myeloma (MM patients, however, there were a small number of studies written about the results of thalidomide therapy in non-transplant MM patients. We therefore conducted a retrospective study of 42 consecutive patients with newly diagnosed and relapsed/refractory MM treated with thalidomide- based induction regimens followed by thalidomide maintenance therapy. Results Induction regimens with thalidomide and dexamethasone, and the oral combination of melphalan, prednisolone and thalidomide were administrated in 22 and 16 patients, respectively. The remaining 4 patients received other thalidomide- containing regimens. Twenty-nine patients received thalidomide as a salvage regimen. Twenty-three out of 26 patients achieving complete remission (CR and very good partial remission (VGPR received thalidomide maintenance. Of the 41 evaluable patients, median time of treatment was 21 months (3- 45 months, ORR was 92.7% with a 63.4% CR/VGPR. With a median follow up of 23 months, 3-year- PFS and 3-year-OS were 58.6 and 72.6%, respectively. Median time to progression was 42 months. While 3-year-PFS and 3-year-OS in non-transplant patients receiving thalidomide maintenance therapy were 67 and 80%, respectively. Conclusions Prolonged thalidomide therapy enhanced survival rate and less frequently developed serious toxicity in non-transplant multiple myeloma patients.

    Full Text Available The combination of rifapentine and moxifloxacin administered daily with other anti-tuberculosis drugs is highly active in mouse models of tuberculosis chemotherapy. The objective of this phase 2 clinical trial was to determine the bactericidal activity, safety, and tolerability of a regimen comprised of rifapentine, moxifloxacin, isoniazid, and pyrazinamide administered daily during the first 8 weeks of pulmonary tuberculosis treatment.Adults with sputum smear-positive pulmonary tuberculosis were randomized to receive either rifapentine (approximately 7.5 mg/kg plus moxifloxacin (investigational arm, or rifampin (approximately 10 mg/kg plus ethambutol (control daily for 8 weeks, along with isoniazid and pyrazinamide. The primary endpoint was sputum culture status at completion of 8 weeks of treatment.121 participants (56% of accrual target were enrolled. At completion of 8 weeks of treatment, negative cultures using Löwenstein-Jensen (LJ medium occurred in 47/60 (78% participants in the investigational arm vs. 43/51 (84%, p = 0.47 in the control arm; negative cultures using liquid medium occurred in 37/47 (79% in the investigational arm vs. 27/41 (66%, p = 0.23 in the control arm. Time to stable culture conversion was shorter for the investigational arm vs. the control arm using liquid culture medium (p = 0.03, but there was no difference using LJ medium. Median rifapentine area under the concentration-time curve (AUC0-24 was 313 mcg*h/mL, similar to recent studies of rifapentine dosed at 450-600 mg daily. Median moxifloxacin AUC0-24 was 28.0 mcg*h/mL, much lower than in trials where rifapentine was given only intermittently with moxifloxacin. The proportion of participants discontinuing assigned treatment for reasons other than microbiological ineligibility was higher in the investigational arm vs. the control arm (11/62 [18%] vs. 3/59 [5%], p = 0.04 although the proportions of grade 3 or higher adverse events were similar (5/62 [8%] in the

    Hematopoietic stem cell transplantation (HSCT) is the only proven curative option for patients with hemoglobinopathies, both thalassemia and sickle cell anemia (SCA). A busulfan-based myeloablative conditioning regimen is the standard of care for HSCT in these patients, although increased treatment-related morbidity, including veno-occlusive disease (VOD), has been demonstrated. Thirty-eight pediatric patients, median age 8 years (range, 6 months to 22 years), suffering from hemoglobinopathy were treated at Rambam Medical Center in Haifa, Israel, between 1998 and 2011. Thirty-four patients had thalassemia major and 4 had SCA. The 38 patients underwent 40 HSCTs, 34 of which were first transplants and 6 second transplants. Most transplants (32/40) were from matched sibling donors. Sources of stem cells were peripheral blood in 30 transplants, bone marrow in 7 transplants, and cord blood in 3 transplants. All received different customized busulfan-based conditioning regimens tailored by pharmacokinetic analysis of busulfan levels. Primary engraftment occurred in 37 of 40 transplants. Neutrophil engraftment (>.5 × 10(9)/L) occurred at a median of 15.3 days post-transplantation (range, 10 to 45). Platelet transfusion independence (>20 × 10(9)/L) occurred at a median of 22.3 days (range, 11 to 60). The rate of 5-year overall survival for thalassemia patients after first transplantation was 90.5% ± 5.3%. The rate of 5-year thalassemia-free survival was 81.7% ± 6.8%. Cumulative incidence of acute graft-versus-host disease (GVHD) was 17.6%. Rate of grades III to IV GVHD was 8.8%. Cumulative incidence of chronic GVHD was 23.5%, with 11.8% incidence of extensive chronic GVHD. One patient developed VOD. Full donor chimerism occurred in 36.4% of patients with class 1 + 2 thalassemia, compared with 78.6% in class 3 thalassemia (P = .049).

    Background The combination of rifapentine and moxifloxacin administered daily with other anti-tuberculosis drugs is highly active in mouse models of tuberculosis chemotherapy. The objective of this phase 2 clinical trial was to determine the bactericidal activity, safety, and tolerability of a regimen comprised of rifapentine, moxifloxacin, isoniazid, and pyrazinamide administered daily during the first 8 weeks of pulmonary tuberculosis treatment. Methods Adults with sputum smear-positive pulmonary tuberculosis were randomized to receive either rifapentine (approximately 7.5 mg/kg) plus moxifloxacin (investigational arm), or rifampin (approximately 10 mg/kg) plus ethambutol (control) daily for 8 weeks, along with isoniazid and pyrazinamide. The primary endpoint was sputum culture status at completion of 8 weeks of treatment. Results 121 participants (56% of accrual target) were enrolled. At completion of 8 weeks of treatment, negative cultures using Löwenstein-Jensen (LJ) medium occurred in 47/60 (78%) participants in the investigational arm vs. 43/51 (84%, p = 0.47) in the control arm; negative cultures using liquid medium occurred in 37/47 (79%) in the investigational arm vs. 27/41 (66%, p = 0.23) in the control arm. Time to stable culture conversion was shorter for the investigational arm vs. the control arm using liquid culture medium (p = 0.03), but there was no difference using LJ medium. Median rifapentine area under the concentration-time curve (AUC0-24) was 313 mcg*h/mL, similar to recent studies of rifapentine dosed at 450–600 mg daily. Median moxifloxacin AUC0-24 was 28.0 mcg*h/mL, much lower than in trials where rifapentine was given only intermittently with moxifloxacin. The proportion of participants discontinuing assigned treatment for reasons other than microbiological ineligibility was higher in the investigational arm vs. the control arm (11/62 [18%] vs. 3/59 [5%], p = 0.04) although the proportions of grade 3 or higher adverse events were

    Background Allogeneic stem cell transplantation is a potential curative approach in patients with multiple myeloma.The very high transplant related mortality associated with standard allogeneic stem cell transplantation is currently the major limitation to wider use of this potentially curative treatment modality. The challenge for clinical investigators is to reduce the incidence of post-transplant complications for patients receiving autologous hematopoietic stem cell transplantion for multiple myeloma. In this study the toxicity and efficacy of modified myeloablative conditioning regimen followed by allogeneic stem cell transplantation was investigated in patients with multiple myeloma.Methods The conditioning regimen consisted of hydroxyurea, cytarabine, busulfan, cyclophosphamide, and semustine.Ten patients underwent allogeneic transplantation among them hydroxyurea (40 mg/kg) was administered twice on day -10 and cytarabine (2 g/m2) was given on day -9, busulfan was administered orally in four divided doses daily for 3 days (days -8 to -6). The dose of busulfan was 12 mg/kg in the protocol followed by cyclophosphamide intravenously over 1hour on days -5 and -4 (1.8 g/m2), and with semustine (Me-CCNU) 250 mg/m2 on day -3.Results Chimerism data were available on all patients and all patients achieved full donor chimerism without graft failure. Six patients had not acute graft-versus-host disease (GVHD, 36.4%; 95% CI:13.9%-38.6%). Two patients (18.2%) developed grade Ⅰ acute GVHD (95% CI:10.9%-35.9%) and grade Ⅱ acute GVHD occurred in one patient (9.1%;95% CI: 8.4%-32.3%). Severe grade Iva GVHD was seen in one patient, who died from acute GVHD. The incidence of chronic GVHD was 22.2% (95% CI: 11.7%-36.7%), among them one died of severe grade IV GVHD and one developed multiorgan failure on day +170; the treatment-related mortality was 22.0% (95% CI: 10.3%-34.1%). The overall 4-year survival rate was 67.8% (95% CI: 16.3%-46.7%). The estimated 4-year

    The results of selected chemotherapy trials and philosophical considerations regarding the role of chemotherapy in Non-Small Cell Lung Cancer are discussed in this review. The issue of treating patients within a clinical or with a "standard regimen" is addressed. In addition, the survival results of randomized trials in which chemotherapy was compared with supportive care and the related quality of life and economic concerns are reviewed. Physicians' attitudes regarding treating advanced non-small cell lung cancer patients as well as the questions of patient selection and the choice of regimen including the consideration of single versus combination regimens are discussed. The results of single agent phase II trials that identified new agents with response rates >/=15%-paclitaxel, docetaxel, vinorelbine, gemcitabine, CPT11-are described, and their implications for the design of new clinical trials are discussed.

    BACKGROUND: Interruption of a non-nucleoside reverse transcriptase inhibitor (NNRTI)-regimen is often necessary, but must be performed with caution because NNRTIs have a low genetic barrier to resistance. Limited data exist to guide clinical practice on the best interruption strategy to use....... METHODS: Patients in the drug-conservation arm of the Strategies for Management of Antiretroviral Therapy (SMART) trial who interrupted a fully suppressive NNRTI-regimen were evaluated. From 2003, SMART recommended interruption of an NNRTI by a staggered interruption, in which the NNRTI was stopped before...... mutations (i.e. 69.2%) achieved HIV-RNA of 400 copies/ml or less compared with those in whom no mutations were detected (i.e. 86.7%; P = 0.05). CONCLUSION: In patients who interrupt a suppressive NNRTI-regimen, the choice of interruption strategy may influence resuppression rates when restarting a similar...

    We recruited consecutive patients with stage III epithelial ovarian, tubal, and peritoneal cancers who had optimal residual tumor after primary cytoreductive surgery and who received intraperitoneal chemotherapy between 2002 and 2012. Two propensity score‑matched sample cohorts were created. We found that the addition of paclitaxel as a second intraperitoneal agent on a 3‑week dosing schedule did not yield significant incremental survival benefits over the intraperitoneal delivery of a single cisplatin‑based regimen. If our findings could be confirmed by a prospective randomized study, then it would be interesting to explore the efcacy of shifting back to a dose‑dense intraperitoneal delivery of paclitaxel or a dose‑dense delivery of a new formulation of paclitaxel for the patients with stage III epithe‑lial ovarian, tubal, and peritoneal cancers.

    @@ Insulin lispro is an insulin analogue that has the advantages of being fast-acting, convenient, and less likely to lead to hypoglycaemic episodes. Previous studies have proven its value in treating both Type 1 and Type 2 diabetes both alone and in combination with different treatment regimens.1,2 However, diabetes is heterogeneous and differs in etiology and clinical characteristics in different ethnic groups. Even with the same insulin treatment, different diets will produce different glycaemic profiles. Diet patterns differ between different ethnic groups. Traditional oriental foods are characterized by a higher proportion of carbohydrates and a lower proportion of fat compared to Caucasian diets. To date, there has been no study on the use of insulin lispro in Chinese diabetic patients. Whether the Chinese dietary pattern will affect the efficacy of insulin lispro treatment remains unknown. Therefore, we conducted this trial to assess the efficacy of insulin lispro treatment in Chinese patients.

    Full Text Available Abstract Background Hydroxyurea (HU is the first approved pharmacological treatment of sickle cell anemia (SCA. The objectives of this study were to develop population pharmacokinetic(PK-pharmacodynamic(PD models for HU in order to characterize the exposure-efficacy relationships and their variability, compare two dosing regimens by simulations and develop some recommendations for monitoring the treatment. Methods The models were built using population modelling software NONMEM VII based on data from two clinical studies of SCA adult patients receiving 500-2000 mg of HU once daily. Fetal hemoglobin percentage (HbF% and mean corpuscular volume (MCV were used as biomarkers for response. A sequential modelling approach was applied. Models were evaluated using simulation-based techniques. Comparisons of two dosing regimens were performed by simulating 10000 patients in each arm during 12 months. Results The PK profiles were described by a bicompartmental model. The median (and interindividual coefficient of variation (CV of clearance was 11.6 L/h (30%, the central volume was 45.3 L (35%. PK steady-state was reached in about 35 days. For a given dosing regimen, HU exposure varied approximately fivefold among patients. The dynamics of HbF% and MCV were described by turnover models with inhibition of elimination of response. In the studied range of drug exposures, the effect of HU on HbF% was at its maximum (median Imax was 0.57, CV was 27%; the effect on MCV was close to its maximum, with median value of 0.14 and CV of 49%. Simulations showed that 95% of the steady-state levels of HbF% and MCV need 26 months and 3 months to be reached, respectively. The CV of the steady-state value of HbF% was about 7 times larger than that of MCV. Simulations with two different dosing regimens showed that continuous dosing led to a stronger HbF% increase in some patients. Conclusions The high variability of response to HU was related in part to pharmacokinetics and

    In patients with relapsed ALL, minimal residual disease (MRD) identified prior to allogeneic hematopoietic cell transplantation (HCT) is a strong predictor of relapse. We report our experience using a combination of reduced-dosing clofarabine, CY and etoposide as a 'bridge' to HCT in eight patients with high risk or relapsed ALL and pre-HCT MRD. All patients had detectable MRD (>0.01%, flow cytometry) at the start of therapy with all eight achieving MRD reduction following one cycle. The regimen was well tolerated with seven grade 3/4 toxicities occurring among four of the eight patients. Five patients (62.5%) are alive, one died from relapse (12.5%) and two from transplant-related mortality (25%). The combination of reduced-dose clofarabine, CY and etoposide as bridging therapy appears to be well tolerated in patients with relapsed ALL and is effective in reducing pre-HCT MRD. PMID:24317126

  4. Comparison of two preoperative chemoradiotherapy regimens for locally advanced rectal cancer: capecitabine alone versus capecitabine plus irinotecan

    International Nuclear Information System (INIS)

    To compare the short-term tumor response and long-term clinical outcome of two preoperative chemoradiotherapy (CRT) regimens for locally advanced rectal cancer. This study included 231 patients scheduled for preoperative CRT using two chemotherapeutic protocols from April 2003–August 2006. Pelvic radiotherapy (50.4 Gy) was delivered concurrently with capecitabine (n = 148) or capecitabine/irinotecan (n = 83). Surgery was performed 4–8 weeks after CRT completion. Tumor responses to CRT were assessed using both radiologic and pathologic measurements. Radiologic responses were evaluated by magnetic resonance volumetry, which was performed at the initial work-up and after completion of preoperative CRT just before surgery. Pathologic responses were assessed with downstaging (ypStage 0-1) and grading tumor regression. Clinical outcomes were evaluated in terms of local control, relapse-free survival, and overall survival rates. Radiologic examination demonstrated that tumor volume decreased by 65.6% in the capecitabine group and 66.8% capecitabine/irinotecan group (p = 0.731). Postoperative pathologic stage determination showed that tumor downstaging occurred in 44.1% of the capecitabine group and 48.6% of the capecitabine/irinotecan group (p = 0.538). The sum of tumor regression grade 3 (near complete response) and 4 (complete response) after CRT were 28.6% in the capecitabine group and 37.5% in the capecitabine/irinotecan group (p = 0.247). There were no significant differences between the two groups in 5-year local control (91.7% vs. 92.5%; p = 0.875), relapse-free survival (80.8% vs. 77.2%; p = 0.685), and overall survival (88.4% vs. 90.4%; p = 0.723). This study revealed no differences in the short-term tumor response and long-term clinical outcome between preoperative capecitabine and capecitabine/irinotecan CRT regimens for locally advanced rectal cancer

    New regimens based on two or more novel agents are sought in order to shorten or simplify the treatment of both drug-susceptible and drug-resistant forms of tuberculosis. PA-824 is a nitroimidazo-oxazine now in phase II trials and has shown significant early bactericidal activity alone and in combination with the newly approved agent bedaquiline or with pyrazinamide with or without moxifloxacin. While the development of PA-824 continues, a potential next-generation derivative, TBA-354, has been discovered to have in vitro potency superior to that of PA-824 and greater metabolic stability than that of the other nitroimidazole derivative in clinical development, delamanid. In the present study, we compared the activities of PA-824 and TBA-354 as monotherapies in murine models of the initial intensive and continuation phases of treatment, as well as in combination with bedaquiline plus pyrazinamide, sutezolid, and/or clofazimine. The monotherapy studies demonstrated that TBA-354 is 5 to 10 times more potent than PA-824, but selected mutants are cross-resistant to PA-824 and delamanid. The combination studies revealed that TBA-354 is 2 to 4 times more potent than PA-824 when combined with bedaquiline, and when administered at a dose equivalent to that of PA-824, TBA-354 demonstrated superior sterilizing efficacy. Perhaps most importantly, the addition of either nitroimidazole significantly improved the sterilizing activities of bedaquiline and sutezolid, with or without pyrazinamide, confirming the value of each agent in this potentially universally active short-course regimen.

    Full Text Available Abstract Background Vitamin D is an important determinant of bone health and also plays a major role in the regulation of the immune system. Interestingly, vitamin D status before the start of highly active antiretroviral therapy (HAART has been recently associated with HIV disease progression and overall mortality in HIV-positive pregnant women. We prospectively studied vitamin D status in HIV individuals on HAART in Belgium. We selected samples from HIV-positive adults starting HAART with a pre-HAART CD4 T-cell count >100 cells/mm3 followed up for at least 12 months without a treatment change. We compared 25-hydroxyvitamin D plasma [25-(OHD] concentration in paired samples before and after 12 months of HAART. 25-(OHD levels are presented using two different cut-offs: Results Vitamin D deficiency was common before HAART, the frequency of plasma 25-(OHD concentrations below 20 ng/ml and 30 below ng/ml was 43.7% and 70.1% respectively. After 12 months on HAART, the frequency increased to 47.1% and 81.6%. HAART for 12 months was associated with a significant decrease of plasma 25-(OHD concentration (p = 0.001. Decreasing plasma 25-(OHD concentration on HAART was associated in the multivariate model with NNRTI-based regimen (p = 0.001 and lower body weight (p = 0.008. Plasma 25-(OHD concentrations decreased significantly in both nevirapine and efavirenz-containing regimens but not in PI-treated patients. Conclusions Vitamin D deficiency is frequent in HIV-positive individuals and NNRTI therapy further decreases 25-(OHD concentrations. Consequently, vitamin D status need to be checked regularly in all HIV-infected patients and vitamin D supplementation should be given when needed.

    Full Text Available Objective: Non-responsiveness to hepatitis B virus (HBV vaccines is not rare in hemato-oncological patients due to disease-associated or treatment-induced immune suppression. Although different strategies have been employed to improve the response rates, to date there is not an approved schedule for HBV immunization in patients with hematological malignancies. We designed a prospective randomized study to evaluate the efficacy of 3 different induction regimens for HBV vaccination. Materials and Methods: In the standard-dose (SD group, total vaccine dose delivered was 40 μg and patients were vaccinated with 20 μg at weeks 0 and 4. In the high-dose dose-intensive (HDDI group, total vaccine dose delivered was 80 μg and patients were vaccinated with 40 μg at weeks 0 and 4. In the high-dose time-intensive (HDTI group, total vaccine dose delivered was 80 μg and patients were vaccinated with 20 μg at weeks 0, 2, 4, and 6. Results: In a cohort of 114 patients, 38.6% responded to HBV vaccination. The response rate in the SD arm, HDDI arm, and HDTI arm was 26.2%, 29.7%, and 44.4%, respectively (p>0.05. Age was the only variable identified as having a negative impact on response. Conclusion: Short of achieving statistical significance, a higher response rate was observed in the HDTI arm. Therefore, this study supports a high-dose, time-intensive HBV vaccine induction regimen in patients with hematological malignancies who are not on chemotherapy.

  8. Pharmacokinetic modeling of an induction regimen for in vivo combined testing of novel drugs against pediatric acute lymphoblastic leukemia xenografts.

    Full Text Available Current regimens for induction therapy of pediatric acute lymphoblastic leukemia (ALL, or for re-induction post relapse, use a combination of vincristine (VCR, a glucocorticoid, and L-asparaginase (ASP with or without an anthracycline. With cure rates now approximately 80%, robust pre-clinical models are necessary to prioritize active new drugs for clinical trials in relapsed/refractory patients, and the ability of these models to predict synergy/antagonism with established therapy is an essential attribute. In this study, we report optimization of an induction-type regimen by combining VCR, dexamethasone (DEX and ASP (VXL against ALL xenograft models established from patient biopsies in immune-deficient mice. We demonstrate that the VXL combination was synergistic in vitro against leukemia cell lines as well as in vivo against ALL xenografts. In vivo, VXL treatment caused delays in progression of individual xenografts ranging from 22 to >146 days. The median progression delay of xenografts derived from long-term surviving patients was 2-fold greater than that of xenografts derived from patients who died of their disease. Pharmacokinetic analysis revealed that systemic DEX exposure in mice increased 2-fold when administered in combination with VCR and ASP, consistent with clinical findings, which may contribute to the observed synergy between the 3 drugs. Finally, as proof-of-principle we tested the in vivo efficacy of combining VXL with either the Bcl-2/Bcl-xL/Bcl-w inhibitor, ABT-737, or arsenic trioxide to provide evidence of a robust in vivo platform to prioritize new drugs for clinical trials in children with relapsed/refractory ALL.

    The treatment of adults who present with rare pediatric tumors is not characterized well in the literature. We report an instance of a 40-year-old African American woman with a diagnosis of choroid plexus carcinoma admitted to the intensive care unit for severe sepsis seven days after receiving chemotherapy consisting of carboplatin (350 mg/m(2) on Days 1 and 2 plus etoposide 100 mg/m(2) on Days 1-5). Her laboratory results were significant for an absolute neutrophil count of 0/µL and blood cultures positive for Capnocytophagia species. She was supported with broad spectrum antibiotics and myeloid growth factors. She eventually recovered and was discharged in stable condition. The management of adults with malignancies most commonly seen in pediatric populations presents substantial challenges. There are multiple age-specific differences in renal and hepatic function that explain the need for higher dosing in pediatric patients without increasing the risk of toxicity. Furthermore, differences in pharmacokinetic parameters such as absorption, distribution, and clearance are present but are less likely to affect patients. It is expected that the pediatric population will have more bone marrow reserve and, therefore, less susceptible to myelosuppression. The extrapolation of pediatric dosing to an adult presents a problematic situation in treating adults with malignancies that primarily effect pediatric patients. We recommend extrapolating from adult treatment regimens with similar agents rather than extrapolating from pediatric treatment regimens to reduce the risk of toxicity. We also recommend the consideration of adding myeloid growth factors. If the treatment is tolerated without significant toxicity, dose escalation can be considered.

    Full Text Available Allogeneic hematopoietic stem cell transplantation (AHSCT is the treatment of choice for young patients with severe aplastic anemia (SAA. The association of antithymocyte globulin (ATG and cyclophosphamide (CY is the most frequently used conditioning regimen for this disease. We performed this retrospective study in order to compare the outcomes of HLA-matched sibling donor AHSCT in 41 patients with SAA receiving cyclophosphamide plus ATG (ATG-CY, N = 17 or cyclophosphamide plus busulfan (BU-CY, N = 24. The substitution of BU for ATG was motivated by the high cost of ATG. There were no differences in the clinical features between the two groups, including age, gender, cytomegalovirus status, ABO match, interval between diagnosis and transplant, and number of total nucleated cells infused. No differences were observed in the time to neutrophil and platelet engraftment, or in the risk of veno-occlusive disease and hemorrhage. However, there was a higher risk of mucositis in the BU-CY group (71 vs 24%, P = 0.004. There were no differences in the incidence of neutrophil and platelet engraftment, acute and chronic graft-versus-host disease, and transplant-related mortality. There was a higher incidence of late rejection in the ATG-CY group (41 vs 4%, P = 0.009. Although the ATG-CY group had a longer follow-up (101 months than the BU-CY group (67 months, P = 0.04, overall survival was similar between the groups (69 vs 58%, respectively, P = 0.32. We conclude that the association BU-CY is a feasible option to the conventional ATG-CY regimen in this population.

Here, we directly compare the immune response and benefit of the intradermal (ID protocol for rabies vaccine delivery with the intramuscular (IM route. Methods: Sixty health workers who were willing to participate in this study have been randomly selected and grouped into ID, IM, and control groups, each with 20 volunteers. The Thai Red Cross ID- and Zangreb IM-protocols have been applied to the respective group. The sera of the volunteers were collected at day 0, week 1, week 3, week 4, month 3, month 6, month 9, and month 12 after the first vaccination. Anti-rabies virus IgG was detected using PlateliaTM Rabies II Kit (Bio-Rad. Results: Anti-rabies IgG could be detected in the ID-group at one week. The ID-vaccine delivery induced a slightly higher maximum antibody titer compared to IM, though not statistically significant (p>0.05. ID vaccination caused less adverse reactions and produces longer lasting protective immune response.  Cost minimization analysis (CMA on the provincial and national PEP data in 2009-2011 shows that the ID-delivery will reduce the total cost for a completed regimen by USD 28.5, and would have saved the Indonesian government budget approximately USD 3.6 and 4.3 million for complete regimens in Bali and Indonesia, respectively. Conclusion: The ID administration of anti-rabies vaccine induces a similar immune response compared to that of intramuscular injection. It also produces longer lasting protective immune response. It offers additional advantages of potential net cost savings as well as decreasing the pressure on vaccine availability due to the high number of dog bite cases.

    Full Text Available Multidrug-resistant tuberculosis (MDR-TB treatment in Bangladesh is empiric or based on qualitative drug-susceptibility testing (DST by comparative growth in culture media with and without a single drug concentration.Adult patients were enrolled throughout Bangladesh during the period of 2011-2013 at MDR-TB treatment initiation. Quantitative DST by minimum inhibitory concentration (MIC testing for 12 first and second-line anti-TB drugs was compared to pretreatment clinical characteristics and treatment outcomes. MIC values at or one dilution lower than the resistance breakpoint used for qualitative DST were categorized as borderline susceptible, and MIC values one or two dilutions greater as borderline resistant.Seventy-four patients were enrolled with a mean age of 35 ± 15 years, and 51 (69% were men. Of the rifampin isolates with MIC >1.0 μg/ml, 12 (19% were fully susceptible or borderline susceptible to rifabutin (MIC ≤ 0.5 μg/ml. Amikacin was fully susceptible in 73 isolates (99%, but kanamycin in only 54 (75% (p<0.001. Ofloxacin was borderline susceptible in 64%, and fully susceptible in only 14 (19% compared to 60 (81% of isolates fully susceptible for moxifloxacin (p<0.001. Kanamycin non-susceptibility and receipt of the WHO Category IV regimen trended with interim treatment failure: adjusted odd ratios respectively of 5.4 [95% CI 0.82-36.2] (p = 0.08 and 7.2 [0.64-80.7] (p = 0.11.Quantitative MIC testing could impact MDR-TB regimen choice in Bangladesh. Comparative trials of higher dose or later generation fluoroquinolone, within class change from kanamycin to amikacin, and inclusion of rifabutin appear warranted.

    In allogeneic hematopoietic cell transplantation (HCT), donor T cell-mediated graft versus host leukemia (GVL) and graft versus autoimmune (GVA) activity play critical roles in treatment of hematological malignancies and refractory autoimmune diseases. However, graft versus host disease (GVHD), which sometimes can be fatal, remains a major obstacle in classical HCT, where recipients are conditioned with total body irradiation or high-dose chemotherapy. We previously reported that anti-CD3 conditioning allows donor CD8(+) T cells to facilitate engraftment and mediate GVL without causing GVHD. However, the clinical application of this radiation-free and GVHD preventative conditioning regimen is hindered by the cytokine storm syndrome triggered by anti-CD3 and the high-dose donor bone marrow (BM) cells required for induction of chimerism. Histone deacetylase (HDAC) inhibitors such as suberoylanilide hydroxamic acid (SAHA) are known to induce apoptosis of cancer cells and reduce production of proinflammatory cytokines by nonmalignant cells. Here, we report that SAHA inhibits the proliferative and cytotoxic activity of anti-CD3-activated T cells. Administration of low-dose SAHA reduces cytokine production and ameliorates the cytokine storm syndrome triggered by anti-CD3. Conditioning with anti-CD3 and SAHA allows induction of chimerism with lower doses of donor BM cells in old nonautoimmune and autoimmune lupus mice. In addition, conditioning with anti-CD3 and SAHA allows donor CD8(+) T cell-mediated GVA activity to reverse lupus glomerulonephritis without causing GVHD. These results indicate that conditioning with anti-CD3 and HDAC inhibitors represent a radiation-free and GVHD-preventative regimen with clinical application potential.

The objective of this study was to define, from the UK payer perspective, the cost-effectiveness of an antiemetic regimen using aprepitant, a selective neurokinin-1 receptor antagonist, for patients receiving chemotherapy for breast cancer. Methods: A decision-analytic model was developed to compare an aprepitant regimen (aprepitant, ondansetron, and dexamethasone with a standard UK antiemetic regimen (ondansetron, dexamethasone, and metoclopramide for expected costs and health outcomes after single-day adjuvant chemotherapy for breast cancer. The model was populated with results from patients with breast cancer participating in a randomized trial of CINV preventative therapy for cycle 1 of single-day chemotherapy. Results: During 5 days after chemotherapy, 64% of patients receiving the aprepitant regimen and 47% of those receiving the UK comparator regimen had a complete response to antiemetic therapy (no emesis and no rescue antiemetic therapy. A mean of £37.11 (78% of the cost of aprepitant was offset by reduced health care resource utilization costs. The predicted gain in quality-adjusted lifeyears (QALYs with the aprepitant regimen was 0.0048. The incremental cost effectiveness ratio (ICER with aprepitant, relative to the UK comparator, was £10,847/QALY, which is well below the threshold commonly accepted in the UK of £20,000–£30,000/QALY. Conclusion: The results of this study suggest that aprepitant is cost-effective for preventing CINV associated with chemotherapy for patients with breast cancer in the UK health

    Full Text Available PURPOSE: Oral fluoropyrimidine (S-1, capecitabine has been considered as an important part of various regimens. We aimed to evaluate the efficacy and safety of S-1-based therapy versus capecitabine -based therapy in gastrointestinal cancers. METHODS: Eligible studies were identified from Pubmed, EMBASE. Additionally, abstracts presented at American Society of Clinical Oncology (ASCO conferences held between 2000 and 2013 were searched to identify relevant clinical trials. The outcome included overall survival (OS, progression-free survival (PFS, overall response rate (ORR, disease control rate (DCR and advent events. RESULTS: A total of 6 studies (4 RCTs and 2 retrospective analysis studies containing 790 participants were included in this meta-analysis, including 401 patients in the S-1-based group and 389 patients in the capecitabine-based group. Results of our meta-analysis indicated that S-1-based and capecitabine-based regimens showed very similar efficacy in terms of PFS (HR 0.92, 95% CI 0.78-1.09, P = 0.360, OS (HR 1.01, 95% CI 0.84-1.21, P = 0.949, ORR (HR 1.04, 95% CI 0.87-1.25, P = 0.683 and DCR (HR 1.02, 95% CI 0.94-1.10, P = 0.639. There was also no significant difference in toxicity between regimens other than mild more hand-foot syndrome in capecitabine-based regimens. CONCLUSION: Both the S-1-based and capecitabine-based regimens are equally active and well tolerated, and have the potential of backbone chemotherapy regimen in further studies of gastrointestinal cancers.

  16. Particle size distribution of nicotine in mainstream smoke from 2R4F, Marlboro Medium, and Quest1 cigarettes under different puffing regimens.

    Nicotine's dose and rate of delivery to the brain play an important role in its addiction and cardiovascular effects. Nicotine is mainly present in the particulate phase of cigarette smoke, and since particle size distribution controls the deposition behavior of particles in the respiratory tract, changes in the particle size distribution can produce variations in its regional and total dose to the lung. These variations can change its absorption rate and delivery to the brain. The particle size distribution of mainstream smoke (MS) varies with changes in puffing regimen and cigarette design and composition. This study examined nicotine in different particle size fractions of MS generated from 2R4F, Marlboro Medium, and Quest1 cigarettes using 3 puffing regimens: (1) FTC-like puff, 35 ml over 2 s; (2) short puff, 50 ml over 2 s; and (3) long puff, 100 ml over 10 s. MS was generated in a chamber at 37 degrees C and >95% relative humidity (RH), and size-segregated particles were collected using RJR cascade impactors. Particle size distribution was determined by spectrophotometry. Nicotine was analyzed using gas chromatography and mass spectrometry. Results showed that nicotine speciates in larger particles (1.1-1.9 microm diameter) under the long puffing regimen and in smaller particles (0.4-1.1 microm diameter) under the short puffing regimen, while mass median aerodynamic diameter of mainstream smoke particles was found to be approximately constant (0.9-1.0 microm) for the three puffing regimens. Overall, changes in puffing regimen have a significant effect on particle size distribution of nicotine and its deposited dose. PMID:19496699

    A 27-year-old male bodybuilder was studied during a 30-day precontest period when his goal was to lose fat and retain muscle mass. Weighted dietary intakes were obtained for each day of the study. The subject trained 6 days per week with weights and included an aerobic component on most days. Ergogenic drugs and a diuretic were self-administered. At the contest, the subject placed in the top three for his weight division. The strict diet enabled the subject to lose fat weight predictably in preparation for the contest. However, some weight lost was lean body tissue, suggesting the rate of loss was too fast. Blood chemistry studies revealed abnormalities, including hemoconcentration and alterations in cholesterol metabolism, which could have placed the subject at risk for thromboembolic phenomena because of increased blood viscosity. Those abnormalities could reflect the use of ergogenic drugs. For this subject, bodybuilding included diet, exercise, and drug regimens, which are common among competitive athletes.

    For patients with recurrent/metastatic (R/M) head and neck squamous cell carcinoma (SCCHN) limited therapeutic options exist. Only a subset of patients is suitable for combination chemotherapy regimens. Biweekly docetaxel plus cetuximab might be an alternative option. Thus, we performed this retrospective analysis in unselected patients in order to investigate the efficacy and safety of this regimen. Thirty-one patients receiving off protocol docetaxel (50 mg/m2) plus cetuximab (500 mg/m2) biweekly were included. Data collection included baseline demographic, response rate (ORR), disease control rate (DCR), overall survival (OS), progression free survival (PFS) as well as toxicity. OS and PFS were 8.3 months (95% CI 4.8–11.8) and 4.0 months (95% CI 1.0–7.0), respectively. Three (9.7%) patients achieved a complete response and one patient (3.2%) a partial response. The DCR was 41.9% and we observed an ORR of 12.9%. The one-year survival rate was 25.8%. The therapy was well tolerated and the most common grade 3/4 adverse events were neutropenia (19.4%), hypomagnesaemia (12.9%) and acne-like rash (9.7%). Biweekly cetuximab/docetaxel is an effective regimen and well tolerated in R/M SCCHN patients not suitable for platinum doublet treatment. Further evaluation of this regimen in prospective clinical trials is warranted.

    Aim: The aim was to assess the influence of two irrigation regimens having ethylenediaminetetraacetic acid (EDTA) and ethylenediaminetetraacetic acid with cetrimide (EDTAC) as final irrigants, respectively, on the dentine wettability for AH Plus sealer by comparing its contact angle formed to the irrigated dentine. Materials and Methods: Study samples were divided into two groups (n = 10). The groups were irrigated with 3% sodium hypochlorite (NaOCl) solution followed by either 17% EDTA or 17% EDTAC solution. AH Plus was mixed, and controlled volume droplet (0.1 mL) of the sealer was placed on the dried samples. The contact angle was measured using a Dynamic Contact Angle Analyzer and results were analyzed using SPSS 21.0 and 2 sample t-test. Results: There was a significant difference in the contact angle of AH Plus formed to the dentine irrigated with the above two regimens. AH Plus showed significantly lower contact angle with the regimen having EDTAC as a final irrigant than the one with EDTA (P < 0.05). Conclusion: An irrigation regimen consisting of NaOCl with either EDTA or EDTAC solution as a final irrigant influences the dentine wettability and contact angle of a sealer. EDTAC as a final irrigant facilitates better dentin wettability than EDTA for AH Plus to promote its better flow and adhesion. PMID:26180409

    Full Text Available Upon HIV infection diagnosis, an 8-month-old boy was transferred for evaluation of worsening respiratory distress requiring mechanical ventilation. Pneumocystis jirovecii pneumonia (PCP was diagnosed; the boy also had a nonhealing ulcer at the site of vaccination with Statens Serum Institut (Danish strain Bacillus Calmette-Guérin (BCG vaccine and associated axillary lymphadenopathy. PCP treatment resulted in weaning from mechanical ventilation. Antimycobacterial treatment was immediately attempted but was discontinued because of hepatotoxicity. Over several months, he developed splenic lesions and then disseminated skin and cystic bone lesions. M. bovis was repeatedly cultured from both skin and bone lesions despite various multidrug antimycobacterial regimens which included linezolid. Eventually, treatment with a regimen of rifabutin, isoniazid, ethambutol, and linezolid led to definitive cure. Clinicians should consider a linezolid-containing regimen for treatment of severe disseminated BCG infection, especially if other drug regimens have failed. Although drug toxicity is a particular concern for young children, this patient received linezolid for 13 months without serious toxicity. This case also highlights the need for universal screening among pregnant women to prevent vertical transmission of HIV. Finally, routine immunization with BCG vaccine at birth should be questioned in countries with low and declining burden of tuberculosis.

    The determination of an optimal dosing regimen is a critical step to enhance the drug efficacy and avoid toxicity. Rational dosing recommendations based on mathematical considerations are increasingly being adopted in the process of drug development and use. In this paper, we propose a quantitative approach to evaluate the efficacy of antibiotic agents. By integrating both pharmacokinetic (PK) and pharmacodynamic (PD) information, this approach gives rise to a unified formalism able to measure the cause-effect of dosing regimens. This new pharmaco-metric allows to cover a whole range of antibiotics, including the two well known concentration and time dependent classes, through the introduction of the Hill-dependency concept. As a direct fallout, our formalism opens a new path toward the bioequivalence evaluation in terms of PK and PD, which associates the in vivo drug concentration and the in vitro drug effect. Using this new approach, we succeeded to reveal unexpected, but relevant behaviors of drug performance when different drug regimens and drug classes are considered. Of particular notice, we found that the doses required to reach the same therapeutic effect, when scheduled differently, exhibit completely different tendencies for concentration and time dependent drugs. Moreover, we theoretically confirmed the previous experimental results of the superiority of the once daily regimen of aminoglycosides. The proposed methodology is appealing for its computational features and can easily be applicable to design fair clinical protocols or rationalize prescription decisions. PMID:23201275

Moreover, the impact of different treatment regimens on T-cell phenotype reconstitution remains unknown. We conducted a prospective randomized study of 17 renal transplant patients to determine the pharmacokinetics of total and active (bound to human cells) rATG and T-cell phenotype reconstitution after rATG administration. Patients received rATG at a total dose of 6mg/kg, administered either as 1.5mg/kg/day on days 0-3 (Group 1, n=8) or 3mg/kg on days 0 and 3 (Group 2, n=9). All patients received tacrolimus, mycophenolate mofetil and steroids. Blood samples were assayed for total rATG by enzyme linked immunosorbent assay and active rATG by flow cytometry. Maximum concentrations and terminal half-lives were similar between the two groups but at month 3 Group 1 had significantly lower values for total rATG (concentration was 6.2±1.1μg/mL versus 10.2±2.9μg/mL in Group 2, p=0.027) and total rATG dose-normalized AUC (374±83dayg/mL versus 508±149dayg/mL in Group 2, p=0.046). Time to sub-therapeutic levels (<1μg/mL) of active rATG was significantly shorter in Group 1 (18.75±6.9days versus 20±7.5days in Group 2, p<0.001). rATG induced significant depletion followed by slow reconstitution of CD3(+), CD4(+) and CD8(+) cells, with no marked differences between groups. B-cell count was unaffected, whereas CD3(-)CD56(+) NK-cell depletion was observed in both groups. rATG induced a significant decrease in the proportion of naïve CD4(+) T-cells, which plateaued after month 1 in Group 1 and after month 6 in Group 2. The proportion of central memory CD4(+) T-cells increased to a similar extent in both groups (Group 1: 38±18% at baseline, 74±23% at one year, p=0.009; Group 2: 32±14% at baseline, 65±14% at one year, p=0.001). In conclusion, our results suggest that the dosing regimen for r

    AIM: To prospectively investigate the effectiveness and patient's tolerance of two low-cost bowel cleansing preparation protocols based on magnesium citrate only or the combination of magnesium citrate and senna. METHODS: A total of 342 patients who were referred for colonoscopy underwent a colon cleansing protocol with magnesium citrate alone ( n = 160) or magnesium citrate and senna granules ( n = 182). The colonoscopist rated the overall efficacy of colon cleansing using an established score on a 4-point scale. Patients were questioned before undergoing colonoscopy for side effects and symptoms during bowel preparation. RESULTS: The percentage of procedures rescheduled because of insufficient colon cleansing was 7% in the magnesium citrate group and 4% in the magnesium citrate/senna group ( P = 0.44). Adequate visualization of the colonic mucosa was rated superior under the citramag/senna regimen ( P = 0.004). Both regimens were well tolerated, and did not significantly differ in the occurrence of nausea, bloating or headache. However, abdominal cramps were observed more often under the senna protocol (29.2%) compared to the magnesium citrate only protocol (9.9%, P < 0.0003). CONCLUSION: The addition of senna to the bowel preparation protocol with magnesium citrate significantly improves the cleansing outcome.

    Full Text Available Abstract Background This study compares the costs and effects of a regimen with ritonavir-boosted tipranavir (TPV/r to a physician-selected genotypically-defined standard-of-care comparator protease inhibitor regimen boosted with ritonavir (CPI/r in HIV infected patients that were previously exposed to antiretroviral therapy in the Netherlands. Methods We compared the projected lifetime costs and effects of two theoretical groups of 1000 patients, one receiving a standard of care regimen with TPV/r as a component and the other receiving a standard of care regimen with CPI/r. A 3-stage Markov model was formulated to represent three different consecutive HAART regimens. The model uses 12 health states based on viral load and CD4+ count to simulate disease progression. The transition probabilities for the Markov model were derived from a United States cohort of treatment experienced HIV patients. Furthermore, the study design was based on 48-week data from the RESIST-2 clinical trial and local Dutch costing data. Cost and health effects were discounted at 4% and 1.5% respectively according to the Dutch guideline. The analysis was conducted from the Dutch healthcare perspective using 2006 unit cost prices. Results Our model projects an accumulated discounted cost to the Dutch healthcare system per patient receiving the TPV/r regimen of €167,200 compared to €145,400 for the CPI/r regimen. This results in an incremental cost of €21,800 per patient. The accumulated discounted effect is 7.43 life years or 6.31 quality adjusted life years (QALYs per patient receiving TPV/r, compared to 6.91 life years or 5.80 QALYs per patient receiving CPI/r. This translates into an incremental effect of TPV/r over CPI/r of 0.52 life years gained (LYG or 0.51 QALYs gained. The corresponding incremental cost effectiveness ratios (iCERs are €41,600 per LYG and €42,500 per QALY. Conclusion We estimated the iCER for TPV/r compared to CPI/r at approximately €40

    Background Given the increasing number of patients who require dual antiplatelet (DAP) therapy and electrophysiological device (EPD) placement, perioperative antiplatelet management is a current challenge. In this study, we investigated the incidence of pocket hema-toma formation after EPD placement in patients undergoing DAP therapy or an alternative low-molecular-weight heparin (LMWH) regimen. Methods This clinical observational study was performed from July 2010 to July 2012. In total, 171 patients were enrolled in the analysis after meeting the inclusion criteria. These patients were divided into two groups: 86 patients were treated with DAP therapy at the time of device implantation, and the DAP therapy was discontinued for 5 to 7 days and replaced with enoxaparin before device implantation in the other 85 patients. Adenosine phosphate (ADP)-mediated platelet aggregation and arachidonic acid-induced platelet aggregation were tested preoperatively. We compared the incidence of pocket hematoma between the two groups and the association of pocket hematoma develop-ment with ADP-mediated platelet aggregation and arachidonic acid-induced platelet aggregation.Results The incidence of pocket hema-toma in the patients who continued DAP was lower than that in the patients who replaced the dual antiplatelet regimen with LMWH (3.49%vs. 16.47%, respectively;X2 = 6.66,P < 0.01). Among the patients who continued DAP therapies, the rate of ADP-mediated platelet aggre-gation inhibition in patients with pocket hematomas was higher than that in patients without pocket hematomas. None of the patients under-going DAP or enoxaparin therapy developed pocket infection, thromboembolic events, or other serious complications. Multiple logistic re-gression analysis revealed that LMWH therapy was an independent risk factor for the development of pocket hematoma (RR = 0.054, 95%CI = 0.012-0.251). Furthermore, patients undergoing LMWH therapy were 5.1-fold more likely to develop pocket

    Full Text Available Little evidence about the effects of antenatal iron supplementation on infant anaemia is available. The aim was to compare effects on six-month-old infants' Haemoglobin (Hb concentration and anaemia of daily iron-folic acid (IFA, twice-weekly IFA with or without other micronutrients (MMN and usual antenatal care in rural Vietnam.Secondary data analysis from: a prospective population-based observational study (OS which examined effects of antenatal psychosocial factors, anaemia and iron deficiency on infant development and health; and a three-arm cluster randomised trial (CRT of different antenatal iron supplementation regimens. In the OS 497 women (<20 weeks gestation from 50 randomly-selected communes participated, and in the CRT 1,258 pregnant women (<16 weeks gestation in 104 communes were allocated randomly to trial arms. The main outcome was six-month-old infant Hb concentration. Baseline data included women's socio-demographic characteristics, reproductive health, Hb and serum ferritin. Mean differences in infant Hb and odds ratios of infant anaemia between CRT arms and OS were calculated by multivariable regression models, controlling for baseline differences and clustering, using robust standard errors. Infant anaemia prevalence was 68.6% in the OS, 47.2% daily IFA, 53.5% weekly IFA, and 50.3% MMN conditions. After adjustment, mean infant haemoglobin levels in daily IFA (mean difference = 0.95 g/dL; 95%CI 0.7-11.18; weekly IFA (0.91; 95%CI 0.69-1.12 and MMN (1.04; 95%CI 0.8-1.27 were higher than in the OS. After adjustment there were lower odds ratios of anaemia among infants in the daily IFA (OR = 0.31; 95% CI 0.22-0.43, weekly IFA (0.38; 95%CI 0.26-0.54 and MMN (0.33; 95%CI 0.23-0.48 groups than in the OS.Infant anaemia is a public health problem in Vietnam and other resource-constrained countries. All supplementation regimens could have clinically significant benefits for Hb and reduce anaemia risk among six-month-old infants

    The inflammatory process plays an important role in sulfur mustard (HD) injury and HD pathogenesis, suggesting that anti-inflammatory treatments applied as soon as possible following HD injury may reduce tissue damage and accelerate healing. This study used the HD dermal weanling swine model to investigate the efficacy of two non-steroidal anti-inflammatory drugs, capsaicin and diclofenac, when applied in combination with the steroid, clobetasol. The therapeutic regimen was also investigated with respect to initiation of treatment post-exposure, frequency and duration. Yorkshire-cross pigs were randomly assigned to experimental groups, corresponding to all combinations of treatment (capsaicin with clobetasol or diclofenac with clobetasol), onset time (1, 2 or 4 h post-exposure), treatment duration (1, 3 or 5 days) and frequency of applications (2, 3 or 4 per day). For each animal, two sites on the ventral abdomen were exposed to 400 μL of neat HD for 8 min to achieve superficial dermal (SD) lesions and two sites were exposed to 400 μL neat HD for 30 min to achieve deep dermal (DD) lesions. Each treatment regimen was tested against a SD and a DD injury. Untreated SD and DD lesion sites served as within-animal controls. Assessments, up to one week post-challenge, included digital photographs, clinical assessments (lesion size measurements and modified Draize scoring), transepidermal water loss (TEWL), reflectance colorimetry and histopathologic evaluations that included an estimate for depth of injury and wound healing parameters. Diclofenac plus clobetasol treatment resulted in significant reductions in lesion contracture and modified Draize scores, increased barrier function (decreased TEWL), and increased healing as determined by histopathology for both SD and DD injury when compared with untreated sites and sites treated with capsaicin plus clobetasol. An increased duration of treatment from 1 to 5 days was most commonly associated with decreased

    Full Text Available Abstract Objective To study the effectiveness and tolerance of an antiretroviral therapy (ART regimen composed of the antiretroviral agents (ARVs stavudine (d4T plus didanosine (ddI plus efavirenz (EFV in patients with advanced HIV infection in Senegal. Design and methods This was an open-label, single-arm, 18-month trial in treatment-naive patients. The primary virologic end point was the percentage of patients with plasma HIV RNA Results The staging of HIV disease, performed using the definitions of the US Centers for Disease Control and Prevention (CDC, was CDC stage B or C for all 40 recruited patients. At baseline, the mean CD4+ cell count was 133 ± 92/mcL (± standard deviation [SD]; range 1–346, and 23% of patients had CD4+ cell counts below 50/mcL. The mean baseline plasma HIV RNA level was 5.5 ± 0.4 log10 copies/mL (± SD; range 4.6–5.9. The proportion of patients with plasma HIV-1 RNA below 500 copies/mL fell during the study from 73% (95% CI [56; 85] at M6 to 56% (95% CI [41; 73] at M12 and 43% (95% CI [27; 59] at M18. Plasma HIV-RNA was below 50 copies/mL in 50% of study subjects (95% CI [31; 66] at M6, 43% (95% CI [27; 59] at M12, and 33% (95% CI [19; 49] at M18. The mean increase in the CD4+ cell count was 105 ± 125/mcL (n = 38 at M3 and 186 ± 122/mcL (n = 21 at M18. Eight patients died, including 6 because of infectious complications. The last viral load (VL value before death was Conclusion Virologic efficacy combination therapy with d4T, ddI, and EFV was measured by the percentage of patients with plasma HIV RNA values below 500 copies/mL and 50 copies/mL; for both parameters, virologic efficacy decreased during the study period. This is explained by the high mortality rate (20% and treatment modifications due to adverse events (13%. These data strengthen the recently revised World Health Organization (WHO guidelines advocating initiation of highly active antiretroviral therapy (HAART before profound CD4 lymphocyte

    AIM: To evaluate the efficacy and acceptability of magnesium citrate and a single dose of oral sodium phosphate (45 mL) solution for morning colonoscopy bowel preparation.METHODS: A total of 159 patients were randomly assigned to receive two split doses of 90 mg of sodium phosphate (Group Ⅰ, n = 79) or magnesium citrate (250 mL,the day before the procedure) followed by 45 mL of sodium phosphate (the day of procedure, Group Ⅱ, n =80). The quality of bowel cleansing and the acceptability of each regimen were compared, including the satisfaction,taste, willing to repeat and adverse effects of each regimen.RESULTS: The quality of bowel cleansing of Group Ⅱ was as good as that of Group Ⅰ (An Aronchick scale score of good or excellent: 70.9% vs 81.0%, respectively,P = 0.34; the Ottawa system score: 4.4 ± 2.6 vs 3.8± 3.0, respectively, P = 0.76). There was no statistically significant difference between both groups with regard to acceptability, including the satisfaction, taste and willingness to repeat the regimen. A significantly greater number of older patients (over 65 years old) in Group Ⅱ graded the overall satisfaction as satisfactory (48.1%vs 78.1%, respectively; Group Ⅰ vs Group Ⅱ, P = 0.01).There were no significant adverse reactions. CONCLUSION: Magnesium citrate and a single dose of sodium phosphate was as effective and tolerable as the conventional sodium phosphate regimen and is a satisfactory option.

    Given the increasing budget impact of Hepatitis C virus (HCV) treatment, robust real-world cost data are essential for healthcare decision-makers to evaluate and understand the costs and benefits of these treatments. To determine the direct cost of treating HCV infection in a hospital-based ambulatory care setting in Ireland based on available data from the Irish national hepatitis C treatment registry. A microcosting study of the direct costs of patients with hepatitis C treated with interferon-based and interferon-free direct-acting antiviral regimens was conducted. Attendance at the outpatient clinic for clinical assessment, the quantity of resources used per patient, the medication prescribed and the identification and timing of staff involvement was measured and combined to establish a mean cost of treatment per patient and a cost per sustained virological response (SVR). One hundred and sixty-eight patients were included in the analysis; 119 treated with interferon-based direct-acting antiviral regimens and 47 treated with interferon-free regimens. The mean costs of treatment with the interferon-based regimens per patient were €38 286 (95% CI €35 305-€41 061). The cost per SVR was €62 457. The mean cost of treatment with interferon-free regimens per patient was €55 734 (95% CI €50 906-€60 880). The cost per SVR was €81 873. Real-world cost data provide valuable information to enhance reimbursement decisions. While the direct costs associated with hepatitis C treatment in Ireland are substantial, it is reasonable to expect that the mean cost of treatment and the cost per SVR will reduce as patients with less advanced disease are treated with interferon-free therapies.

    This study was aimed to investigate the clinical characteristics of relapsed-refractory acute myeloid leukemia (AML) with AML1-ETO⁺, and its therapeutic efficacy and side effects when decitabine combined with modified CAG regimen was used. Clinical data of 5 cases of AML with AML1-ETO⁺ from January 2013 to Agust 2013 were analyzed retrospectively. The analyzed data included age, sex, initial symptoms, peripheral blood and bone marrow characteristics. Meanwhile, the therapeutic effecacy and side effects of decitabine combined with modified CAG regimen were evaluated. The 5 patients were with median age of 35 (17-43) years. Among these 5 patients, 2 patients were relapsed and other 3 patients were relapsed-refractory patients, their median white blood cell count was 12.55 (7.8-66.55) × 10⁹/L, median platelets count was 44 (20-72) × 10⁹/L, median hemoglobin level was 110 (77-128) g/L, median lactate dehydrogenase level was 312.9 U/L (123.6-877.8) at the initial diagnosis. The results showed that after decitabine combined with modified CAG regimen was administered, 4 patients achieved complete remission, 1 patient did not achieve remission, the overall remission rate was 80% (4/5). The main side effects of this regimen was myelosuppression, these were no new lung infection and other serious complications, one case without complete remission treated with FLAG once again died of heart failure when being mobilized for transplantation. It is concluded that according to preliminary results of decitabine combined with modified CAG regimen for relapsed and refractory AML patients with AML1-ETO⁺ displays higher remission rate and lower side effects, which worthy to further explore for clinal application.

    Full Text Available Emerging antimalarial drug resistance in mobile populations remains a significant public health concern. We compared two regimens of dihydroartemisinin-piperaquine in military and civilians on the Thai-Cambodian border to evaluate national treatment policy.Efficacy and safety of two and three-day regimens of dihydroartemisinin-piperaquine were compared as a nested open-label evaluation within a malaria cohort study in 222 otherwise healthy volunteers (18% malaria-infected at baseline. The first 80 volunteers with slide-confirmed Plasmodium falciparum or vivax malaria were randomized 1:1 to receive either regimen (total dose 360 mg dihydroartemisinin and 2880 mg piperaquine and followed weekly for up to 6 months. The primary endpoint was malaria recurrence by day 42. Volunteers with vivax infection received primaquine at study discharge with six months follow-up.Eighty patients (60 vivax, 15 falciparum, and 5 mixed were randomized to dihydroartemisinin-piperaquine. Intention-to-treat all-species efficacy at Day 42 was 85% for the two-day regimen (95% CI 69-94 and 90% for the three-day regimen (95% CI 75-97. PCR-adjusted falciparum efficacy was 75% in both groups with nearly half (45% still parasitemic at Day 3. Plasma piperaquine levels were comparable to prior published reports, but on the day of recrudescence were below measurable in vitro piperaquine IC50 levels in all falciparum treatment failures.In the brief period since introduction of dihydroartemisinin-piperaquine, there is early evidence suggesting declining efficacy relative to previous reports. Parasite IC50 levels in excess of plasma piperaquine levels seen only in treatment failures raises concern for clinically significant piperaquine resistance in Cambodia. These findings warrant improved monitoring of clinical outcomes and follow-up, given few available alternative drugs.ClinicalTrials.gov NCT01280162.

    Full Text Available Background and Aims: To investigate the clinical charcteristics and treatment response of patients with chronic coinfection of hepatitis B virus (HBV and hepatitis C virus (HCV. .Methods: The study included nine consecutive patients with chronic HBV/HCV coinfection. Diagnosis was performed by liver biopsy and/or clinical and laboratory evaluation. Six patients received 48 weeks of pegylated interferon (Peg-IFN monotherapy or combination therapy with Peg-IFN plus ribavirin according to the dominant virus..Results: The dominant infection was hepatitis C in six cases. Of the four patients who completed the treatment and follow-up period, only one had a sustained viral response (SVR to HCV, but unfortunately, this was accompanied by a reactivation of HBV-DNA without flaring of hepatitis. No patient had an HBV-DNA response. Another two patients are still in the follow-up period. One of these patients had an undetectable level of HCV-RNA, and the other had an undetectable level of HBV-DNA at baseline. At the end of treatment, both HBV-DNA and HCV-RNA were negative in these patients. The HBV-DNA-negative patient showed a transient HBV-DNA positivity after clearance of HCV-RNA..Conclusions: In the majority of HBV/HCV coinfected cases in our sample, HCV was the dominant virus. Currently, the standard treatment regimens are not effective for clearance of HBV and/or HCV. HCV clearance may induce HBV reactivation without flaring of hepatitis.

    Extranodal natural killer/T-cell lymphoma (ENKTL) is an aggressive neoplasm with a poor outcome. Novel L-asparaginase-based treatment regimens, such as GELOX (gemcitabine, oxaliplatin, and L-asparaginase) and P-gemox (gemcitabine, oxaliplatin, and pegaspargase), have shown promising results against stage IE/IIE ENKTL. To define the general applicability of P-gemox, in a retrospective analysis we examined the efficacy and safety of P-gemox in a cohort of 117 patients with newly diagnosed or relapsed/refractory ENKTL. Treatment included 2 to 8 cycles of P-gemox: intravenous gemcitabine (1250 mg/m2) and oxaliplatin (85 mg/m2) and intramuscular pegaspargase (2500 IU/m2) on day 1 and repeated every 2 weeks, or intravenous gemcitabine (1000 mg/m2) on days 1 and 8 and intravenous oxaliplatin (130 mg/m2) and intramuscular pegaspargase (2500 IU/m2) on day 1 and repeated every 3 weeks. Upon completion of treatment, the overall response rate was 88.8%, and responses were similar for newly diagnosed and relapsed/refractory patients. After a median follow-up of 17 months, the 3-year overall and progression-free survival rates were 72.7% and 57.8%, respectively. Multivariate analysis showed that CR after treatment was the most significant factor affecting survival. P-gemox thus appears to be an effective and well-tolerated treatment for patients with ENKTL.

    Full Text Available Introduction: Brucellosis, a serious zoonosis, is a widespread disease in many countries, especially the developing ones, with an annual report of 500,000 new cases to the World Health Organization (WHO. Although successful results have been achieved by the combination therapies recommended by the WHO, their relapse rates have been high, and therefore, the most effective agents with least side-effects are still undetermined. Materials and Methods: An observational study has been prospectively carried out from 2007 to 2010 in the Infectious Clinics of Hashemi-nejad and Imam Reza Hospitals, Mashhad, Iran. In this study, among the patients of brucellosis, whose diseases were recently diagnosed, 50 patients, receiving one of the two common authentic regimens of doxycycline plus rifampin for eight weeks or ciprofloxacin plus rifampin for six weeks, were selected. The diagnosis was based on the presence of signs and symptoms compatible with brucellosis, including a positive Wright and 2ME tests, with titers equal to or more than 1/160 and 1/40 respectively. Results: The cure rate was the same for the groups (P=0.55. However, the relapse rate was much more for the latter (P= 0.02. Conclusion: Doxycycline plus rifampin was considered better than ciprofloxacin plus rifampin for the treatment of acute brucellosis.

    Adaptation of skin barrier function and interleukin-1α (IL-1α) content in diapered and nondiapered skin are poorly characterized in newborns receiving standard skin care. In a monocentric, prospective pilot study 44 healthy, full-term neonates were randomly assigned to skin care with baby wipes (n = 21) or water-moistened washcloth (n = 23) at each diaper change. Transepidermal water loss (TEWL), skin hydration, skin-pH, IL-1α, and epidermal desquamation were measured on days 2, 14, and 28 postpartum. Microbiological colonization was evaluated at baseline and on day 28. Significantly lower TEWL was found on the buttock in the group using baby wipes compared to water. IL-1α and skin hydration significantly increased and pH decreased independent of skin care regimen. IL-1α was significantly higher in diapered skin compared to nondiapered skin. Although skin care with wipes seems to stabilize TEWL better than using water, the skin condition and microbiological colonization were comparable using both cleansing procedures. Increase of epidermal IL-1α may reflect postnatal skin barrier maturation. These data suggest that neither of the two cleansing procedures harms skin barrier maturation within the first four weeks postpartum. Longer observations on larger populations could provide more insight into postnatal skin barrier maturation. PMID:22260233

    Full Text Available Breast cancer is the leading cancer among South African women. There is limited South African epidemiological data on triple-negative breast cancer (TNBC. Taxpas was a nonrandomized observational survey conducted in multiple centres in South Africa from April 2004 to December 2010. 1632 female patients diagnosed with breast cancer, with a median age of 51 years, were enrolled in the survey. Patients were treated on a docetaxel-based chemotherapy regimen. The objective of the study was to assess epidemiological data and survival data. The incidence of TNBC was 14%. The one-year survival rate for the total cohort was 84%. The one-year survival rate for patients with early stage and metastatic breast cancer was recorded as 94% and 65%, respectively. Patients with TNBC stage III (all ages and stage IV (≤50 years had statistically significant worse 1-year survival rate compared to N-TNBC patients of the same age and stages. Conclusion. The incidence of TNBC in South Africa which is 14% is comparable to global incidence. The 1-year survival data for certain subgroups supports the literature saying that TNBC carries a worse prognosis compared to N-TNBC. Women ≤50 years diagnosed with late stage TNBC carried the worst prognosis in this survey.

    Despite an abundance of research on calorie restriction (CR) altering gonadal and appetite regulating hormones, the sexual behavioural consequences of CR remain to be examined systematically. This study compared the sexual behaviour, partner preference, serum testosterone and leptin levels of male adult Hooded Wistar rats administered a CR (continuous 25%, 50% CR or a temporary restriction) with ad libitum fed controls. The temporary restriction (Previous CR) failed to alter sexual behaviour, partner preference and levels of testosterone and leptin. The moderately 25% CR males did not demonstrate an impairment in sexual behaviour but did demonstrate a reduced level of attractiveness to females in one measure of partner preference. Sexual performance was affected by a substantial CR, as the CR 50% group exhibited a longer latency to the first intromission, indicating alteration in sexual arousal. Females also consistently demonstrated a clear preference for the control group compared to the CR 50% group. These findings indicate a possible reduction in the overall reproductive potential of the substantially CR animals. Testosterone levels were equally suppressed by both the 25% and 50% CR, while leptin levels were only reduced in the CR 50% group. Leptin, rather than testosterone, may have influenced the impairment in sexual behaviour only demonstrated by the substantially CR animals. Testosterone, may, however, play a role in modulating the preference of control over CR males, as attractiveness was totally reduced by a substantial CR, and partially reduced by a moderate restricted regimen.

    Full Text Available Helicobacter pylori, a Gram-negative bacterium found in the human stomach, is often present in patients with chronic gastritis. Traditional treatment for H. pylori infection includes metronidazole or clarithromycin, both being associated with development of resistance. In this retrospective report, we describe our clinical experience using a multi-drug treatment regimen for pediatric H. pylori that included nitazoxanide, a newer nitrothiazole benzamide compound used in treating intestinal protozoa infections. Charts were identified for patients who were treated between January 1, 2008 and December 31, 2013 with an ICD-9-CM code 041.86 (H. pylori and who underwent elective endoscopy. All patients were exposed to nitazoxanide for 3 days plus azithromycin, and cefixime (or another 3rd-generation oral cephalosporin for 7-10 days, plus a proton pump inhibitor for 30 days. The clinical cure criteria were predefined. There were 127 individual occurrences or cases identified for inclusion in the review, with 111 occurrences meeting the inclusion criteria. The success rate or clinical cure for the new therapy combination prescribed as defined prior to the chart review was 99 out of 111 cases (89.2%. There were no serious adverse events observed or reported during the treatment of any patient. Approximately 10% of patient charts reflected minor complaints of nausea, vomiting or abdominal cramps during the time of active drug therapy. Nitazoxanide appears to be an effective and well-tolerated option for use in combination with other agents to treat H. pylori-induced gastritis.

    The treatment for infections in hospitalized patients can be summarized in the timely start of empirical therapy, followed by adjustment on the basis of isolates and microbial susceptibilities. Initial therapy may be based on international guidelines. However, to know local frequencies of bacterial and fungal strains together with patterns of drug resistance should be a better approach to therapy. REGIMEN is a retrospective observational study of all consecutive recorded bacterial and fungal isolates, collected between October 2009 and August 2011 from patients admitted in a 53-bedded ward of internal medicine of a non-teaching Italian hospital. We investigated type of samples and of microorganisms, patterns of susceptibility and resistance to antibiotics, and in-hospital mortality. A total of 504 samples were examined (244 from urine, 189 from blood and 71 from skin and various exudates). Participants were old (mean age, 83 years), and so overall mortality was high (20 %). There were high frequencies of drug resistance; only 27.9 % of urinary gram-negatives and 52.6 % of blood gram-negatives were susceptible to levofloxacin. Susceptibility profiles compatible with the presence of extended-spectrum beta-lactamases were present in 64.2 % of gram-negative strains, and 10.1 % were also resistant to carbapenems. ESKAPE organisms account for a third of all bacterial infections. Local patterns of drug resistance should influence empirical antibiotic therapy for patients admitted in internal medicine wards, where mortality is high.

    2016-03-01

    Selective decontamination of the digestive tract (SDD) using combinations of oral non-absorbable antibiotics has been proposed as a means of preventing multidrug-resistant (MDR) infections. The minimum inhibitory concentrations (MICs) of rifaximin (RIFAX) were determined against 262 Gram-negative and Gram-positive bacterial isolates by broth microtitre assay. Rifampicin (RIF) was used as a comparator in the analysis. Synergistic interactions between RIFAX and polymyxin B (PMB) were assessed by using the chequerboard method and calculating the fractional inhibitory concentration index (FICI). The antimicrobial activities of both RIFAX and RIF were similar with little variation in the overall MIC distributions for Gram-negative non-fermenters and Gram-positive bacteria. However, against Enterobacteriaceae higher MICs (>16mg/L) were observed for RIFAX than for RIF (50% vs 27%). Amongst the 262 isolates tested, 100 could be considered resistant to RIFAX. Overall, the combination of RIFAX and PMB was more active against all of the isolates tested compared with either drug alone, with reductions of 2-11 doubling dilutions in individual MICs. Potent synergy was observed with the RIFAX+PMB combination using FICI criteria (FICI range 0.02-0.5). The data presented here suggest that combination therapy may be significantly more effective against isolates with RIFAX and/or PMB resistance and could be considered as part of a SDD regimen aimed at reducing enteric carriage of MDR pathogens in colonised and infected patients.

    Despite great advances in haemophilia care in the last 20 years, a number of questions on haemophilia therapy remain unanswered. These debated issues primarily involve the choice of the product type (plasma-derived vs. recombinant) for patients with different characteristics: specifically, if they were infected by blood-borne virus infections, and if they bear high or low risk of inhibitor development. In addition, the most appropriate treatment regimen in non-inhibitor and inhibitor patients compel physicians operating at the haemophilia treatment centres (HTCs) to take important therapeutic decisions, which are often based on their personal clinical experience rather than on evidence-based recommendations from published literature data. To know the opinion on the most controversial aspects in haemophilia care of Italian expert physicians, who are responsible for common clinical practice and therapeutic decisions, we have conducted a survey among the Directors of HTCs affiliated to the Italian Association of Haemophilia Centres (AICE). A questionnaire, consisting of 19 questions covering the most important topics related to haemophilia treatment, was sent to the Directors of all 52 Italian HTCs. Forty Directors out of 52 (76.9%) responded, accounting for the large majority of HTCs affiliated to the AICE throughout Italy. The results of this survey provide for the first time a picture of the attitudes towards clotting factor concentrate use and product selection of clinicians working at Italian HTCs. PMID:24533954

    Full Text Available Accurate assessment of left ventricular function in rodent models is essential for the evaluation of new therapeutic approaches for cardiac diseases. In our study, we provide new insights regarding the role of a 1.5 Tesla (T magnetic resonance imaging (MRI device and different anesthetic regimens on data validity. As dedicated small animal MRI and echocardiographic devices are not broadly available, we evaluated whether monitoring cardiac function in small rodents with a clinical 1.5 T MRI device is feasible. On a clinical electrocardiogram (ECG synchronized 1.5 T MRI scanner we therefore studied cardiac function parameters of mice with chronic virus-induced cardiomyopathy. Thus, reduced left ventricular ejection fraction (LVEF could be verified compared to healthy controls. However, our results showed a high variability. First, anesthesia with medetomidine, midazolam and fentanyl (MMF led to depressed cardiac function parameters and more variability than isoflurane gas inhalation anesthesia, especially at high concentrations. Furthermore, calculation of an average ejection fraction value from sequenced scans significantly reduced the variance of the results. To sum up, we introduce the clinical 1.5 T MRI device as a new tool for effective analysis of left ventricular function in mice with cardiomyopathy. Besides, we suggest isoflurane gas inhalation anesthesia at high concentrations for variance reduction and recommend calculation of an average ejection fraction value from multiple sequenced MRI scans to provide valid data and a solid basis for further clinical testing.

    Each stage of root canal treatment should be carried out to the highest possible standard. The access cavity is arguably the most important technical stage, as subsequent preparation of the root canal(s) can be severely comprised if this is not well executed. Inadequate access can lead to canals being left untreated, poorly disinfected, difficult to shape and obturate, and may ultimately lead to the failure of the treatment. This paper highlights common features in root canal anatomy and outlines basic principles for locating root canals and producing a good access cavity. It also explores each phase of the preparation in detail and offers suggestions of instruments that have been specifically designed to overcome potential difficulties in the process. Good access design and preparation will result in an operative environment which will facilitate cleaning, shaping and obturation of the root canal system in order to maximise success.

  5. Surface preparation of niobium

    International Nuclear Information System (INIS)

    Any discussion of surface preparation for superconducting rf-surfaces is certainly connected with the question what is the best recipe for achieving high Q-values and high break-down fields. Since the break-down in a cavity is not understood so far and because several mechanisms play a role, it also is not possible to give one recipe which always works. Nevertheless in the past certain preparation techniques for niobium surfaces have been developed and certain rules for preparation can be applied. In the following the to-days state of the art will be described and it is attempted to give a short description of the surface in conjunction with the methods of surface treatments, which generally can be applied to niobium cavities.

    Using the method of NGR-spectroscopy with the aid of 241Am isotope chemical state of transuranium elements in the volume and on the surface of amalgams is studied. Amalgam preparation was realized in a simplified electrolytic cell. It is shown that in the process of amalgam preparation the first order of reaction as to actinide is observed; americium is distributed gradually over the volume and it is partially sorbed by the surface of glass capillary. NGR spectrum of dry residue after mercury distillation at 200 deg C points to the presence of americium-mercury intermetal compounds

    Full Text Available BACKGROUND: It is unknown whether HIV-positive patients experiencing virologic failure (VF on boosted-PI (PI/r regimens without drug resistant mutations (DRM by standard genotyping harbor low-level PI resistant variants. CASTLE compared the efficacy of atazanavir/ritonavir (ATV/r with lopinavir/ritonavir (LPV/r, each in combination with TVD in ARV-naïve subjects. OBJECTIVE: To determine if VF on an initial PI/r-based regimen possess low-level resistant variants that may affect a subsequent PI-containing regimen. METHODS/RESULTS: Patients experiencing VF on a Tenofovir/Emtricitabine+PI/r regimen were evaluated by ultra deep sequencing (UDS for mutations classified/weighted by Stanford HIVdb. Samples were evaluated for variants to 0.4% levels. 36 VF subjects were evaluated by UDS; 24 had UDS for PI and RT DRMs. Of these 24, 19 (79.2% had any DRM by UDS. The most common UDS-detected DRM were NRTI in 18 subjects: M184V/I (11, TAMs(7 & K65R(4; PI DRMs were detected in 9 subjects: M46I/V(5, F53L(2, I50V(1, D30N(1, and N88S(1. The remaining 12 subjects, all with VLs12 for ATV or LPV: N88S (at 0.43% level-mutational load 1,828 in 1 subject on ATV; I50V (0.44%-mutational load 110 and L76V (0.52%-mutational load 20 in 1 subject each, both on LPV. All VF samples remained phenotypically susceptible to the treatment PI/r. CONCLUSION: Among persons experiencing VF without PI DRMs with standard genotyping on an initial PI/r regimen, low-level variants possessing major PI DRMs were present in a minority of cases, occurred in isolation, and did not result in phenotypic resistance. NRTI DRMs were detected in a high proportion of subjects. These data suggest that PIs may remain effective in subjects experiencing VF on a PI/r-based regimen when PI DRMs are not detected by standard or UDS genotyping.

    Full Text Available Introduction: In HIV+ patients exhibiting multidrug resistance (MDR, NRTIs often have little activity, increased toxicity, drug interactions and add unnecessary treatment costs. The 48 week VERITAS study demonstrated that these patients can have a safe and effective simplification of salvage regimen by removing inactive NRTIs as determined by genotypic data. Virological, immunological, clinical and financial outcomes were evaluated at an additional 96 weeks of follow-up. Materials and Methods: MDR patients with an undetectable viral load (VL on a stable regimen containing at least four ARVs (including one inactive NRTI were enrolled in an open-label, prospective simplification trial, where one inactive NRTI was removed at baseline (BL. A second NRTI could be removed at week 24 if the regimen contained at least five ARVs at enrolment. Results: 31 male patients participated. The mean length of treatment was 14 years, with a median CD4 count of 525. The BL regimen consisted of 4 ARVs in 22 patients (71% and 5 ARVs in 9 patients (29%. 3TC or FTC was removed in 29 patients (94%, and either AZT or TDF was interrupted in 2 others. Four patients had a second NRTI stopped. One patient was removed at W26 as an active NRTI was removed for creatinine elevation. 30 well-controlled patients continued follow-up after W48. At W144, six patients had additional changes in their ARV regimen. Half were due to toxicity (jaundice, neuropathy and nephrotoxicity while the other half were the result of treatment simplification. None of the patients exhibited virologic failure at the time of treatment change and maintained undetectable VLs throughout the entire follow-up. These six patients had a mean gain of 79 CD4 (p=0.17 compared to baseline. 22 of the 24 patients (92% with no changes in ARV therapy after W48 had undetectable VLs. The other two had confirmed virologic failure, one with genotypic resistance. All 24 had elevated CD4 counts (mean +118 CD4, p<0.0001. No

    Background Several reports of chloroquine treatment failure and resistance in Plasmodium vivax malaria from Southeast Asian countries have been published. Present study was undertaken to assess the efficacy of chloroquine-primaquine (CQ-PQ) combined regimen for the treatment of P. vivax malaria patients who were catered by the selected primary health centres (PHCs) of Udupi taluk, Udupi district, Karnataka, India. Method Five PHCs were selected within Udupi taluk based on probability proportional to size. In-vivo therapeutic efficacy assessment of CQ (1500 mg over three days) plus PQ (210 mg over 14 days) regimen was carried out in accordance with the World Health Organization’s protocol of 28 days follow-up among microscopically diagnosed monoinfection P. vivax cohort. Results In total, 161 participants were recruited in the study of which, 155 (96.3%) participants completed till day 28 follow-up, fully complied with the treatment regimen and showed adequate clinical and parasitological response. Loss to follow up was noted with 5 (3.1%) participants and non-compliance with treatment regimen occurred with one participant (0.6%). Glucose-6-phosphate dehydrogenase deficiency (G6PDd, <30% of normal mean activity) was noted among 5 (3.1%) participants and one of them did develop PQ induced dark-brown urination which subsided after PQ discontinuation. G6PDd patients were treated with PQ 45 mg/week for eight weeks while PQ was discontinued in one case with G6PD 1.4 U/g Hb due to complaint of reddish-brown coloured urine by 48 hours of PQ initiation. Nested polymerase chain reaction test revealed 45 (28%) cases as mixed (vivax and falciparum) malaria. Conclusions The CQ-PQ combined regimen remains outstandingly effective to treat uncomplicated P. vivax malaria in Udupi taluk and thus it should continue as first line regimen. For all P. vivax cases, G6PD screening before PQ administration must be mandatory and made available in all PHCs. PMID:27315280

    Full Text Available Target-controlled infusion (TCI provides precise pharmacokinetic control of propofol concentration in the effect-site (Ce, eg. brain. This pilot study aims to evaluate the feasibility and optimal TCI regimen for flexible bronchoscopy (FB sedation.After alfentanil bolus, initial induction Ce of propofol was targeted at 2 μg/ml. Patients were randomized into three titration groups (i.e., by 0.5, 0.2 and 0.1 μg/ml, respectively to maintain stable sedation levels and vital signs. Adverse events, frequency of adjustments, drug doses, and induction and recovery times were recorded.The study was closed early due to significantly severe hypoxemia events (oxyhemoglobin saturation <70% in the group titrated at 0.5 μg/ml. Forty-nine, 49 and 46 patients were enrolled into the 3 respective groups before study closure. The proportion of patients with hypoxemia events differed significantly between groups (67.3 vs. 46.9 vs. 41.3%, p = 0.027. Hypotension events, induction and recovery time and propofol doses were not different. The Ce of induction differed significantly between groups (2.4±0.5 vs. 2.1±0.4 vs. 2.1±0.3 μg/ml, p = 0.005 and the Ce of procedures was higher at 0.5 μg/ml titration (2.4±0.5 vs. 2.1±0.4 vs. 2.2±0.3 μg/ml, p = 0.006. The adjustment frequency tended to be higher for titration at 0.1 μg/ml but was not statistically significant (2 (0∼6 vs. 3 (0∼6 vs. 3 (0∼11. Subgroup analysis revealed 14% of all patients required no further adjustment during the whole sedation. Comparing patients requiring at least one adjustment with those who did not, they were observed to have a shorter induction time (87.6±34.9 vs. 226.9±147.9 sec, p<0.001, a smaller induction dose and Ce (32.5±4.1 vs. 56.8±22.7 mg, p<0.001; 1.76±0.17 vs. 2.28 ±0.41, p<0.001, respectively, and less hypoxemia and hypotension (15.8 vs.56.9%, p = 0.001; 0 vs. 24.1%, p = 0.008, respectively.Titration at 0.5 μg/ml is risky for FB sedation.

    educational levels. The patients were submitted to a regimen of exclusive parenteral antibiotic, only during the hospitalization period (ATP-EX group. These results were compared with results obtained in a historical cohort in the same hospital (20 cases submitted to a regimen of hospital parenteral antibiotic therapy complemented with ambulatory oral treatment (ATP+VO group. The patients were evaluated clinically on the occasion of periodic return visits in order to identify cases of recurrence and infectious complications. RESULTS: one patient from the ATP+VO group needed to be readmitted to the hospital on the 6th day after her discharge from the hospital with a diagnosis of endometritis recrudescence. No complications were observed among patients from ATP-EX group. CONCLUSION: for the treatment of puerperal endometritis, there was no additional advantage in using supplementary oral antibiotic therapy after patient discharge. The results using exclusive parenteral antibiotic treatment during hospitalization time indicate that it is effective and can be safely used in a population of low socioeconomic level.

    Generic substitution of antiepileptic drugs (AEDs) is still a matter of controversy and concern among clinicians and patients. We aimed to assess intrasubject variation in plasma concentrations of lamotrigine (LTG), levetiracetam (LEV) and topiramate (TPM) after generic substitution compared with a stable brand-name drug regimen in a population of patients with epilepsy. A retrospective analysis was performed on prospectively collected and stored data from our therapeutic drug monitoring (TDM) database for the years 2009-2014. The main outcome variable was the proportion of patients who, after switching from branded to generic formulations, showed a greater than ±20% change in AED plasma concentrations compared to the proportion of control patients showing a change in AED plasma concentrations of the same extent while receiving stable branded formulations over repeated TDM tests. Fifty patients on LTG, 27 on LEV and 16 on TPM showing at least one TDM test while receiving generic products fulfilled the inclusion/exclusion criteria for the analysis and were compared with 200 control patients for LTG, 120 for LEV and 80 for TPM. The proportion of patients showing an intrasubject change greater than ±20% in AED plasma concentrations was similar in the brand name vs generic group compared with the control one for LTG (22% vs 33%) and LEV (44% vs 38%), while it was higher in the control group for TPM (41% vs 6%, pTPM plasma concentrations can be observed even in patients stabilized with the same brand name product over time. This suggests that any change in plasma AED concentration and possible related clinical effects after generic substitution may be not necessarily related to the switch. Our results should be confirmed by large, prospective, blinded, randomized controlled studies in people with epilepsy. PMID:26987080
