Abstract
An EMS-based forward genetic screen was conducted in an apoptotic null background to identify genetic aberrations that contribute to regulation of cell growth in Drosophila melanogaster . The current work maps the genomic location of one of the identified mutants, L.3.2 . Genetic crosses conducted through the Fly-CURE consortium determined that the gene locus for the L.3.2 mutation is p47 on chromosome 2R.

Abstract
Achievement of a sustained virologic response (SVR) with antiviral therapy significantly improves graft survival in hepatitis C virus (HCV) monoinfected liver transplant (LT) patients. Risks and benefits of HCV therapy in HCV-human immunodeficiency virus (HIV) coinfected LT recipients are not well established. Among 89 HCV-HIV LT recipients in the HIVTR cohort, 39 (23% Black, 79% genotype 1, 83% fibrosis stage ≤ 1) were treated with peginterferon-a2a or a2b plus ribavirin for a median 363 days (14-1373). On intent-to-treat basis, 22% (95% CI: 10-39) and 14% (95% CI: 5-30) achieved an end-of-treatment response (EOTR) and SVR, respectively. By per-protocol analysis (completed 48 weeks of therapy ± dose reductions), 42% and 26% had EOTR and SVR, respectively. Severe adverse events occurred in 85%, with 26% hospitalized with infections and 13% developing acute rejection. Early discontinuations and dose reductions occurred in 38% and 82%, respectively, despite use of growth factors in 85%. Eighteen of 39 treated patients (46%) subsequently died/had graft loss, with 10 (26%) attributed to recurrent HCV. In conclusion, SVR rates are low and tolerability is poor in HCV-HIV coinfected transplant recipients treated with peginterferon and ribavirin. These results highlight the critical need for better tolerated and more efficacious HCV therapies for HCV-HIV coinfected transplant recipients.

Abstract
Chronic inflammation may contribute to human immunodeficiency virus (HIV) persistence through a number of potential pathways. We explored the impact of immunosuppressant therapy on peripheral blood measures of HIV persistence following kidney transplantation. Stored plasma and peripheral blood mononuclear cells prior to transplantation and at weeks 12, 26, 52 and 104 posttransplant were obtained from 91 transplant recipients. In a multivariate model, higher pretransplant plasma HIV RNA level (p < 0.0001) and a longer duration of follow-up posttransplant (p = 0.09) were associated with higher posttransplant plasma HIV RNA levels. A higher baseline HIV DNA (p < 0.0001) was significantly associated with higher HIV DNA levels posttransplant, while higher CD4+ T cell count (p = 0.001), sirolimus use (p = 0.04) and a longer duration of follow-up (p = 0.06) were associated with lower posttransplant HIV DNA levels. The association between sirolimus exposure and lower frequency of cells containing HIV DNA levels posttransplant suggest that the immune-modifying drugs may affect the level of HIV persistence during effect therapy. Future studies of sirolimus as a reservoir-modifying agent are warranted.

Abstract
INTRODUCTION As more solid organ transplantations are performed in patients infected with human immunodeficiency virus (HIV), post-transplant complications in this population are becoming better defined. METHODS Using serum samples from the Solid Organ Transplantation in HIV: Multi-Site Study, we studied the epidemiology of acquired hypogammaglobulinemia (HGG) after liver transplantation (LT) in 79 HIV-infected individuals with a median CD4 count at enrollment of 288 (interquartile range 200-423) cells/μL. Quantitative immunoglobulin G (IgG) levels before and after LT were measured, with moderate and severe HGG defined as IgG 350-500 mg/dL and <350 mg/dL, respectively. Incidence, risk factors, and associated outcomes of moderate or worse HGG were evaluated using Kaplan-Meier estimator and proportional hazards (PH) models. RESULTS The 1-year cumulative incidence of moderate or worse HGG was 12% (95% confidence interval [CI]: 6-22%); no new cases were observed between years 1 and 2. In a multivariate PH model, higher pre-transplant model for end-stage liver disease score (P = 0.04) and treated acute rejection (P = 0.04) were both identified as significant predictors of moderate or worse HGG. There was a strong association of IgG levels <500 mg/dL with non-opportunistic serious infection (hazard ratio [95% CI]: 3.5 [1.1-10.6]; P = 0.03) and mortality (3.2 [1.1-9.4]; P = 0.04). These associations held after adjustment for important determinants of infection and survival among the entire cohort. CONCLUSION These results suggest that a proportion of HIV-positive LT recipients will develop clinically significant HGG after transplantation.

Abstract
Hepatitis C virus infection is the major cause of end-stage liver disease and the major indication for transplantation (OLTX), including among HIV-HCV co-infected individuals. The age of HCV acquisition differs between haemophilic and non-haemophilic candidates, which may affect liver disease outcomes. The purpose of the study was to compare rates of pre- and post-OLTX mortality between co-infected haemophilic and non-haemophilic subjects without hepatocellular cancer participating in the Solid Organ Transplantation in HIV Study (HIV-TR). Clinical variables included age, gender, race, liver disease aetiology, BMI, antiretroviral therapy, MELD score, CD4 + cell count, HIV RNA PCR and HCV RNA PCR. Time to transplant, rejection and death were determined. Of 104 HIV-HCV positive subjects enrolled, 34 (32.7%) underwent liver transplantation, including 7 of 15 (46.7%) haemophilic and 27 of 89 (30.3%) non-haemophilic candidates. Although haemophilic subjects were younger, median 41 vs. 47 years, P = 0.01, they were more likely than non-haemophilic subjects to die pre-OLTX, 5 (33.3%) vs. 13 (14.6%), P = 0.03, and reached MELD = 25 marginally faster, 0.01 vs. 0.7 years, P = 0.06. The groups did not differ in baseline BMI, CD4, detectable HIV RNA, detectable HCV RNA, time to post-OLTX death (P = 0.64), graft loss (P = 0.80), or treated rejection (P = 0.77). The rate of rejection was 14% vs. 36% at 1-year and 36% vs. 43% at 3-year, haemophilic vs. non-haemophilic subjects, respectively, and post-OLTX survival, 71% vs. 66% at 1-year and 38% vs. 53% at 3-year. Despite similar transplant outcomes, pretransplant mortality is higher among co-infected haemophilic than non-haemophilic candidates.

Abstract
Improvements in human immunodeficiency virus (HIV)-associated mortality make it difficult to deny transplantation based upon futility. Outcomes in the current management era are unknown. This is a prospective series of liver or kidney transplant recipients with stable HIV disease. Eleven liver and 18 kidney transplant recipients were followed for a median of 3.4 years (IQR [interquartile range] 2.9-4.9). One- and 3-year liver recipients' survival was 91% and 64%, respectively; kidney recipients' survival was 94%. One- and 3-year liver graft survival was 82% and 64%, respectively; kidney graft survival was 83%. Kidney patient and graft survival were similar to the general transplant population, while liver survival was similar to the older population, based on 1999-2004 transplants in the national database. CD4+ T-cell counts and HIV RNA levels were stable; and there were two opportunistic infections (OI). The 1- and 3-year cumulative incidence (95% confidence intervals [CI]) of rejection episodes for kidney recipients was 52% (28-75%) and 70% (48-92%), respectively. Two-thirds of hepatitis C virus (HCV)-infected patients, but no patient with hepatitis B virus (HBV) infection, recurred. Good transplant and HIV-related outcomes among kidney transplant recipients, and reasonable outcomes among liver recipients suggest that transplantation is an option for selected HIV-infected patients cared for at centers with adequate expertise.
