Meta-analysis: anti-viral therapy of hepatitis C virus-related liver disease in renal transplant patients.

BACKGROUND: The efficacy and safety of interferon-based therapy in renal transplant recipients with hepatitis C remains unclear, although a number of small clinical trials have been published addressing this issue. AIM: To evaluate efficacy and safety of antiviral therapy with interferon (interferon alone or interferon plus ribavirin) in renal transplant patients with hepatitis C by performing a systematic review of the literature with a meta-analysis of clinical trials. METHODS: The primary outcomes were sustained virological response (as a measure of efficacy) and/or drop-out rate (as a measure of tolerability). We used the random-effects model of DerSimonian and Laird, with heterogeneity and sensitivity analysis. RESULTS: We identified 12 clinical trials (102 unique patients); there was one controlled study. The summary estimate for sustained virological response and drop-out rate was 18.0% (95% CI 7.0-29.0%) and 35.0% (95% CI 20-50%), respectively. The most frequent side-effect requiring interruption of treatment was graft dysfunction (n = 28; 71.7%). Meta-regression analysis showed an inverse and significant association between reference year and drop-out logit rate (P = 0.012); an inverse link between sustained virological response logit rate and frequency of hepatitis C virus genotype 1 (P = 0.067) and cirrhosis (P = 0.08) was found, even if no statistical significance was reached. No publication bias was observed. CONCLUSIONS: Interferon-based therapy of hepatitis C has poor tolerance and safety after renal transplant. The optimal treatment of hepatitis C after renal transplant requires additional agents or alternative therapeutic approaches.

Meta-analysis: terlipressin therapy for the hepatorenal syndrome.

BACKGROUND: The hepatorenal syndrome is a severe and well-known complication of end-stage liver disease, but its management is controversial. Recent reports have shown the efficacy of terlipressin therapy, a vasopressin analogue, in hepatorenal syndrome patients. AIM: To evaluate the efficacy and safety of terlipressin in the treatment of hepatorenal syndrome. METHODS: We performed a systematic review of the literature with a meta-analysis of clinical trials. The primary outcome (as a measure of efficacy) was the rate of responder patients (i.e. patients who had hepatorenal syndrome reversal after terlipressin therapy). The secondary outcomes were the rate of responders who had hepatorenal syndrome recurrence after terlipressin withdrawal, and the drop-out rate (as a measure of tolerability). We used the random effects model of DerSimonian and Laird with heterogeneity and sensitivity analysis. RESULTS: We identified 10 clinical trials (154 unique patients); two (20.0%) were randomized, controlled trials. The pooled rate of patients who reversed hepatorenal syndrome after terlipressin therapy was 0.52 (95% CI, 0.42; 0.61), P = 0.0001; I2 = 24.6%. The pooled frequency of responder patients who showed hepatorenal syndrome recurrence after terlipressin withdrawal was 0.55 (95% CI, 0.40; 0.69), P = 0.00001; I2 = 44.3%. The pooled rate of patients who showed side-effects to terlipressin therapy was 0.29 (95% CI, 0.17; 0.42), P < 0.0001, I2 = 66.6%. The drop-out rate was 0%. The pooled OR for mortality rate in hepatorenal syndrome patients who were not responders to terlipressin vs. responder patients was 5.746 (95% CI, 1.5; 21.9). We did not find any predictive factor of response to terlipressin therapy. CONCLUSIONS: This meta-analysis shows efficacy and safety of terlipressin in the treatment of hepatorenal syndrome. However, a significant number of responder patients relapsed after terlipressin withdrawal. Further studies are in progress to address the link between terlipressin and survival in hepatorenal syndrome patients.

Meta-analysis: the adjuvant role of granulocyte macrophage-colony stimulating factor on immunological response to hepatitis B virus vaccine in end-stage renal disease.

BACKGROUND: Chronic dialysis patients often fail to produce protective antibodies to hepatitis B virus surface antigen after vaccination towards hepatitis B virus (HBV). Several authors suggested a benefit for granulocyte macrophage-colony stimulating factor (GM-CSF) as an adjuvant to HBV vaccination in patients with end-stage renal disease (ESRD). However, consistent information is still lacking. AIMS: To evaluate efficacy and safety of GM-CSF as adjuvant to hepatitis B vaccine in patients with ESRD by performing a systematic review with a meta-analysis of prospective controlled clinical trials (CCTs). METHODS: Only trials comparing the seroresponse rate in study (GM-CSF plus HBV vaccine) versus control (HBV vaccine alone) patients were included. We used the random effects model of DerSimonian and Laird, with heterogeneity and sensitivity analyses. The end-point of interest was the rate of patients showing seroprotective anti-hepatitis B titers at completion of HBV vaccine schedule in study versus control groups. RESULTS: We identified seven studies involving 187 unique patients with ESRD. Only prospective CCTs were included. Pooling of study results showed a significant increase in response rates among study (GM-CSF plus HBV vaccine) versus control (HBV vaccine alone) patients (pooled Odds Ratio, 4.63 [95% Confidence Intervals, 1.42; 15.14]). The P-value was 0.02 for our test of study heterogeneity. CONCLUSIONS: Our meta-analysis showed improved seroprotection rates with HBV vaccine after GM-CSF administration.

Meta-analysis: anti-viral therapy of hepatitis B virus-associated glomerulonephritis.

BACKGROUND: Hepatitis B virus-associated glomerulonephritis is an infrequent complication of chronic hepatitis B virus (HBV) with significant morbidity. A causal association between hepatitis B virus infection and the development of glomerulonephritis remains controversial. Also, the optimal therapy is undefined although several approaches have been made. AIM: To evaluate the efficacy and safety of anti-viral therapy (interferon or lamivudine) in HBV-associated glomerulonephritis by a systematic review and meta-analysis of clinical trials. METHODS: The primary outcome was clinical response (as a measure of efficacy); the secondary outcomes were drop-out rate (as a measure of tolerability), and virological response. We used the random effects model of DerSimonian and Laird, with heterogeneity, sensitivity and meta-regression analyses. RESULTS: We identified six clinical trials (84 unique patients); three had controlled design. The overall estimate for proteinuria remission was 65.2% (95% confidence intervals: 52.7-75.9%), Q-test for heterogeneity = 7.731, P = 0.172, I(2) = 35.327. The overall estimate for hepatitis B e antigen clearance was 62.0% (95% confidence intervals: 50.5-72.2%). The overall estimate for drop-out rate was 12.7% (95% confidence intervals: 6.4-23.6%). Meta-regression analysis showed a significant link between hepatitis B e antigen clearance and logit rate of proteinuria remission after interferon therapy [coefficient -2.585 (S.E. 1.089), P = 0.017]. CONCLUSION: Remission of the nephrotic syndrome is accompanied by clearance of HBV replication, supporting the role of the virus in the pathogenesis of the disease.

Meta-analysis: intradermal vs. intramuscular vaccination against hepatitis B virus in patients with chronic kidney disease.

BACKGROUND: Dialysis patients have suboptimal response towards hepatitis B virus (HBV) vaccine and intradermal hepatitis B virus vaccination has been used to improve the response rate; however, its efficacy remains unclear. DESIGN: Meta-analysis of controlled trials comparing intradermal vs. intramuscular vaccine against HBV among chronic kidney disease patients. IDENTIFICATION: Twelve studies involving 640 unique patients were included if they had controlled design, intervention and control group patients received intradermal or intramuscular vaccine against HBV, respectively. Patients were followed for a minimum of 7 months after the first vaccine dose. MAIN OUTCOME MEASURES: The odds ratio of failure to respond to HBV vaccine among patients who received vaccine by intradermal vs. intramuscular route was the end point of interest. It was calculated at completion of HBV vaccination and over follow-up. RESULTS: Pooling of study results demonstrated a decreased risk of failure to respond to HBV vaccine among patients who were vaccinated by intradermal vs. intramuscular route (pooled odds ratio at completion of vaccine protocol: 0.36; 95% CI: 0.21-0.62; test of study heterogeneity, P = 0.089). This difference did not occur over follow-up (6-60 months after completing vaccine schedule; pooled odds ratio: 1.1; 95% CI: 0.47-2.5). CONCLUSIONS: Dialysis patients show higher seroprotection after intradermal than intramuscular vaccination schedules; this was not apparent over follow-up. Further studies are warranted to assess if the higher seroprotection rates obtained by intradermal route translates into reduced incidence of de novo HBV virus among chronic kidney disease patients.

Meta-analysis: the adjuvant role of thymopentin on immunological response to hepatitis B virus vaccine in end-stage renal disease.

BACKGROUND: It has been calculated that 30-40% of dialysis patients fail to produce antibodies to HBsAg antigen after vaccination towards hepatitis B virus. Several authors have reported on the benefit of thymopentin (TP5) as adjuvant to vaccine against hepatitis B virus in patients receiving regular dialysis. However, consistent information on this issue is still lacking. AIMS: To evaluate efficacy and safety of thymopentin as adjuvant to hepatitis B vaccine in dialysis patients by performing a systematic review with a meta-analysis of clinical trials. METHODS: We used the random effects model of DerSimonian and Laird, with heterogeneity and sensitivity analyses. RESULTS: We identified 11 studies involving 272 unique patients with end-stage renal disease. Only prospective, controlled trials were included. Pooling of study results did not show a significant increase in seroresponse rate among study (thymopentin plus hepatitis B virus vaccine) vs. control (hepatitis B virus vaccine alone) patients; the pooled odds ratio of failure to respond to hepatitis B virus vaccine was 0.677 (95% confidence intervals: 0.285-1.605); no heterogeneity was found (P = 0.0001). Thymopentin significantly improved the seroresponse rate in the subgroup of trials based on greater thymopentin doses (OR: 0.184; 95% CI: 0.085-0.398). CONCLUSIONS: Our meta-analysis showed that thymopentin significantly improved the seroresponse rate towards hepatitis B vaccine only in dialysis patients treated with higher thymopentin doses. The limited number of patients precluded definitive conclusions.

Functional analysis of the regulatory requirements of B-Raf and the B-Raf(V600E) oncoprotein.

The BRAF(V600E) mutation is found in approximately 6% of human cancers and mimics the phosphorylation of the kinase domain activation segment. In wild-type B-Raf (B-Raf(wt)), activation segment phosphorylation is thought to cooperate with negative charges within the N-region for full activation. In contrast to Raf-1, the N-region of B-Raf is constitutively negatively charged owing to the presence of residues D447/D448 and the phosphorylation of S446. Therefore, it has been suggested that this hallmark predisposes B-Raf for oncogenic activation. In this study, we demonstrate that neutralizing mutations of these residues (in particular S446 and S447), or uncoupling of B-Raf from Ras-guanine 5'-triphosphate (GTP), strongly reduce the biological activity of B-Raf in a PC12 cell differentiation assay. We also confirm that S365 is a 14-3-3 binding site, and determine that mutation of this residue rescues the impaired biological activity of B-Raf proteins with a neutralized N-region, suggesting that the N-region opposes a 14-3-3-mediated transition into an inactive conformation. However, in the case of B-Raf(V600E), although complete N-region neutralization resulted in a 2.5-fold reduction in kinase activity in vitro, this oncoprotein strongly induced PC12 differentiation or transformation and epithelial-mesenchymal transition of MCF-10A cells regardless of its N-region charge. Furthermore, the biological activity of B-Raf(V600E) was independent of its ability to bind Ras-GTP. Our analysis identifies important regulatory differences between B-Raf(wt) and B-Raf(V600E) and suggests that B-Raf(V600E) cannot be inhibited by strategies aimed at blocking S446 phosphorylation or Ras activation.

Meta-analysis: the dialysis mode and immunological response to hepatitis B virus vaccine in dialysis population.

BACKGROUND: Patients on maintenance dialysis typically show a suboptimal immune response to hepatitis B virus vaccine compared with the non-uraemic population. Some authors have claimed that dialysis mode has an impact on the immune response to hepatitis B virus vaccine but consistent information is lacking on this issue. AIM: To evaluate the relationship between dialysis mode and immune response to hepatitis B vaccine in dialysis population by performing a systematic review with a meta-analysis of clinical trials. METHOD: We used the random effects model of DerSimonian and Laird; sources of heterogeneity in effect estimates were explored by performing sensitivity analyses. RESULTS: The relative risk of failure to respond to hepatitis B vaccine among patients who underwent maintenance haemodialysis vs. peritoneal dialysis was the end point of interest. We identified 14 clinical trials involving 1211 unique patients on maintenance dialysis. Pooling of study results did not show a significant decreased risk of response to hepatitis B vaccine among haemodialysis patients (overall risk ratio: 1.0, 95% confidence intervals: 0.92-1.1). The P-value was 0.13 for our test of study heterogeneity. CONCLUSION: There is no significant link between dialysis mode and seroresponse to hepatitis B virus vaccine in dialysis population.

Primary and memory T cell responses induced by hepatitis C virus multiepitope long peptides.

To develop a vaccine against hepatitis C virus, we synthesized four long peptides from nonstructural proteins NS3, NS4 and NS5B containing HLA-class I and class II epitopes mainly inducing responses in natural infection. In HLA-A2.1 transgenic mice, the four peptides primed higher CTL responses to 6:7 minimal HLA-A2 epitopes than those induced by the minimal epitopes. HLA-A2.1/HLA-DR1 transgenic mice immunized with one peptide, containing a class II epitope implicated in viral resolution, developed IFNgamma-producing CD4+-T and CD8+-T cells. These peptides recalled HCV-specific IFNgamma-producing cells from HCV-infected patients' PBMC. This support the selection of these domains for inclusion in a vaccine formulation.

Transport barrier inside the reversal surface in the chaotic regime of the reversed-field pinch.

Magnetic field lines and the corresponding particle orbits are computed for a typical chaotic magnetic field provided by a magnetohydrodynamics numerical simulation of the reversed-field pinch. The m = 1 modes are phase locked and produce a toroidally localized bulging of the plasma which increases particle transport. The m = 0 and m = 1 modes produce magnetic chaos implying poor confinement. However, they also allow for the formation of magnetic islands which induce transport barriers inside the reversal surface.

[Coadministration benzodiazepine and antidepressant drugs: the state of art].

SUMMARY: The potential for drug-drug interactions in psychiatric patients is very high as combination psychopharmacotherapy used to treat comorbid psychiatric disorders, to treat the adverse effects of a medication, to augment a medication effect or to treat concomitant medical illnesses, etc. Interactions can be pharmacodynamic or pharmacokinetic in nature. In clinical practice the benzodiazepines (BZD) are often prescribed together with antidepressant drugs for the treatment of depression. Although there has been no convincing evidence to show that such a combination is more effective than antidepressants alone and no clear indication for the use of this combination. Yet, anxiety frequently coexists with depression, and an anxiolytic is often added. But, it is BZD which are systematically prescribed together with antidepressants. However, BZD themselves have no antidepressive effects and we lack firm evidence for or against this combination therapy. We are focused on the pharmacodynamic interactions between anxiolytic such as BZD, and antidepressant drugs which may resulting in a reduction of the effects of one of the drugs. It is known that BZD decrease the serotoninergic transmission. Also, it may be suggested that combined BZD-specific serotonin reuptake inhibitors, should be avoided. This paper reviews, in vitro and in vivo and particularly in clinical, the evidences for drug interactions between BZD and antidepressant drugs. In clinical, all trials that compared antidepressant-benzodiazepine treatment with antidepressant alone for adult patients with major depression were sought by electronic searches of Medline and several other databases (1970 to 2005), combined with hand searching, reference searching and SciSearch.

Folic acid supplementation during methotrexate immunosuppression is not associated with early toxicity, risk of acute graft-versus-host disease or relapse following hematopoietic transplantation.

Methotrexate (MTX) is used as an immunosuppressive agent for acute graft-versus-host disease (GVHD) prophylaxis following hematopoietic cell transplantation (HCT). Concerns that folate intake may impair MTX effectiveness or selectively rescue leukemic cells have led to variations in clinical practice regarding supplemental folic acid during MTX administration. A retrospective, observational study was undertaken to determine the association between folic acid intake (days 0-18 post transplant) and MTX toxicity and efficacy following HCT. The study population consisted of 311 adult patients who received a myeloablative HCT for chronic myelogenous leukemia, all four scheduled doses of MTX, and did not require leucovorin rescue. Multiple linear regression models were used to assess the relationships between folic acid intake (days 0-18 post-HCT) and oral mucositis index (OMI) scores, time to engraftment and risk of detectable acute GVHD. No statistically significant differences in mean OMI scores, time to engraftment, risk of acute GVHD, days to acute GVHD, risk of relapse or survival were observed when comparing patients taking, on average, <400 (14%), 400 (58%) or >400 microg (28%) folic acid per day. Our results suggest that concurrent folic acid supplementation does not change MTX effectiveness or toxicity in this patient population.

Happiness and congruence in older adulthood: a structural model of life satisfaction.

The purpose of this study was to determine how health impairment, socioeconomic status, and social support relate to life satisfaction in later life. Using data from a sample of 320 older adults from The Georgia Centenarian Study, we constructed a structural model of life satisfaction. LISREL analysis was performed to test a two-factor model that included Happiness and Congruence and to determine the relationship of health impairment, socioeconomic status (SES), and social support to Happiness and Congruence, two measures of the Life Satisfaction Index-A (LSI-A). Data were found to provide a satisfactory fit of the model (GFI = 0.94; AFGI = 0.91). Social support and SES were found to have direct effects on health impairment. Health impairment was a key predictor and mediating variable of Happiness and Congruence. Findings also support a relationship between social resources and subjective well-being in later life. In particular, the association between social resources and life satisfaction was mediated through health impairment. These findings offer understanding relative to how health and social resources influence past and present assessments of subjective well-being among the elderly.

Radio-frequency ablation of hepatocellular carcinoma before liver transplantation: a histologic and 'TUNEL' study.

BACKGROUND: Radio-frequency ablation (RFA) is an increasingly used treatment modality for hepatocellular carcinoma (HCC) in patients awaiting liver transplantation (OLTX). The current study evaluates the effectiveness of RFA in this setting based on evaluation of total cell death in explanted native livers. DESIGN: We evaluated 36 tumors from 35 patients with RFA-treated HCC who underwent OLTX at our center between 1998 and 2002. Native livers from OLTX were extensively sampled for histologic evaluation. For each HCC, an estimate ratio of necrotic tumor areas was calculated based on hematoxylin and eosin (H&E) sections. In tumors with 10% or more residual viable areas, Tdt-mediated UTP nick-end labeling (TUNEL) was further performed to assess apoptosis in the morphologically 'viable' areas. A final 'tumor cell death' (TCD) ratio was recalculated for each HCC to include areas of apoptosis identified by TUNEL. RESULTS: Based on H&E evaluation, 22/36 (61.1%) HCC revealed > or = 90% necrosis including 12/36 HCC (33.3%) showing no evidence of residual viable tumor. The overall median tumor necrosis was 79%. When TUNEL findings were added, 26/36 (72.2%) HCC revealed > or = 90% TCD including 14/36 HCC (38.8%) showing complete TCD (median TCD of 88.4%). None of our patients died of HCC while awaiting OLTX. Longer RFA-to-transplant time appears to be associated with a higher TCD rate (median of 154.5 days in patients with less than 90% TCD vs 326 days for patients with > or = 90% TCD; P = 0.019). There was no significant correlation between tumor grade or pre-RFA size of the tumors and TCD rate in RFA-treated HCC (P = 0.11). CONCLUSION: Extensive TCD (88.4% median) can be obtained using RFA for HCC in patients awaiting OLTX. Our TUNEL findings suggest that RFA-induced cell injury could be associated with apoptosis.

Nocardia infections in cats: a retrospective multi-institutional study of 17 cases.

OBJECTIVE: To record 17 cases of nocardiosis in cats from eastern Australia and to compare this series with cases previously reported. DESIGN: Retrospective/prospective study. RESULTS: Nocardia spp infections were diagnosed in 17 cats over 14 years from the three eastern states of Australia. There were no isolates from dogs during this period, but one isolate from a koala and two from dairy cows. The majority of cats presented with spreading lesions of the subcutis and skin associated with draining sinus tract(s). Early cutaneous lesions consisted of circumscribed abscesses. Infections spread at a variable rate, generally by extension to adjacent tissues. Lesions were generally located in regions subjected to cat bite or scratch injuries, including limbs, body wall, inguinal panniculus and nasal bridge. In some other cases, lesions were situated on distal extremities. The clinical course was variable, from chronic, indolent, initially localised infections to acute fulminating disease. Of the 17 cats, 14 were domestic crossbreds and three were purebreds. There was a preponderance of male cats (12 castrated, 1 entire young adult, 1 entire kitten). Nine of 17 cats were 10 years or older. Interestingly, the majority of infections were attributable to N nova. Immediate and/or predisposing causes could be identified in all cases, and included: renal transplantation [one cat]; chronic corticosteroid administration [three cats]; catabolic state following chylothorax surgery [one cat]; fight injuries [seven cats]; FIV infections [three of seven cats tested]. Of the 17 cats, three were apparently cured. Four were thought to be cured, but infection recurred after several months. Three cats responded partially but were euthanased, while another was improving when it died of unrelated complications. Two died despite treatment and two were euthanased without an attempt at therapy. For two cats there were either insufficient records or the patient was lost to follow up. CONCLUSION: Nocardiosis is a rare, serious disease. Currently it is more common in cats than dogs. Nocardial panniculitis may be clinically indistinguishable from the syndrome caused by rapidly growing mycobacteria. Although the prognosis is guarded, patients with localised infections caused by N nova often respond to appropriate therapy. If definitive treatment is delayed because of misdiagnosis, the disease tends to become chronic, extensive and refractory. Insufficient duration of therapy leads to disease recurrence.

Long-term outcome of therapy for 59 cats and 11 dogs with cryptococcosis.

OBJECTIVE: To determine the outcome of therapy in cats and dogs with naturally occurring cryptococcosis. Design Retrospective study of 59 cats and 11 dogs at the University Veterinary Centre Sydney from 1986 to 2004. METHOD: Following detailed analysis of case notes potential associations between patient characteristics, cryptococcal species, retroviral status (cats), disease severity and type of therapy were examined in relation to duration and success of therapy. Treatment protocols based on amphotericin B, fluconazole and itraconazole were compared. RESULTS: Seventy-six percent of feline patients were successfully treated. For cats, the presence of central nervous system disease was the only factor found to influence outcome. Cats with neurological involvement, disseminated disease or refractory disease treated with amphotericin B containing protocols did as well, on average, as cats with less severe disease treated with azole monotherapy. Amphotericin B was thus an effective agent for treating severe cases of cryptococcosis. The median cumulative dose of amphotericin B for cats cured at the first attempt was 16 mg/kg (range 7 to 23 mg/kg). The median duration of treatment required to effect a cure at first attempt was significantly shorter for fluconazole (4 months; range 1 to 8 months) than for itraconazole (9 months; range 3 to 24 months; P = 0. 0191; Mann Whitney U test). The success rate for treatment of canine cases was 55%. No factor appeared to influence disease outcome in dogs. Large cumulative doses of amphotericin B could be administered via the subcutaneous route in both species and generally with minimal nephrotoxicity. Recrudescence occurred in a significant proportion of animals, in some cases despite a reduction of serum latex cryptococcal antigen agglutination test to zero. CONCLUSION: Although the prognosis of cryptococcosis should be described as guarded, a majority of the canine and especially feline patients can be expected to be cured, although treatment is protracted and expensive.

Hepatitis C virus infection and diabetes mellitus in end-stage renal disease: evidence of a negative association.

Epidemiological studies have implicated hepatitis C virus (HCV) infection in the pathogenesis of diabetes mellitus (DM) both in the population as a whole and after solid organ transplantation. Whether this association exists in patients with end-stage renal disease (ESRD) undergoing dialysis is unclear. The aim of this study is to investigate the relationship between HCV and DM in a large group (n=742) of patients with ESRD from Europe and North America. The presence of diabetes was ascertained by using American Diabetes Association guidelines based on fasting glucose measurement and medication history. Presence of HCV infection was assessed by serum testing for anti-HCV antibodies. The prevalence of anti-HCV antibody positive patients was 15% (112/742); the frequency of DM was higher among anti-HCV positive than -HCV negative patients but the difference did not approach statistical significance, 32% (36/112) vs 29.5% (186/630). The frequency of patients with diabetic nephropathy was not higher in anti-HCV positive than -negative patients; 21.4% (24/112) vs 23.3% (147/630), NS. Logistic regression model showed an independent and significant link between anti-HCV seropositive status and raised GPT (P=0.032), male gender (P = 0.0462), positive history of prior renal transplant (P=0.0006), and longer time on dialysis (P=0.00001). In summary, no link between anti-HCV antibody and DM occurred in this ESRD population; there was no association between rate of anti-HCV antibody and diabetic nephropathy.
