An Assessment of HIV-Infected Patients Dying in Care for Deceased Organ Donation in a United States Urban Center : Potential HIV-Infected Deceased Organ Donors

Delayed graft function (DGF) impacts short- and long-term outcomes. We present a model for predicting DGF after renal transplantation. A multivariable logistic regression analysis of 24,337 deceased donor renal transplant recipients (2003-2006) was performed. We developed a nomogram, depicting relative contribution of risk factors, and a novel web-based calculator (http://www.transplantcalculator.com/DGF) as an easily accessible tool for predicting DGF. Risk factors in the modern era were compared with their relative impact in an earlier era (1995-1998). Although the impact of many risk factors remained similar over time, weight of immunological factors attenuated, while impact of donor renal function increased by 2-fold. This may reflect advances in immunosuppression and increased utilization of kidneys from expanded criteria donors (ECDs) in the modern era. The most significant factors associated with DGF were cold ischemia time, donor creatinine, body mass index, donation after cardiac death and donor age. In addition to predicting DGF, the model predicted graft failure. A 25-50% probability of DGF was associated with a 50% increased risk of graft failure relative to a DGF risk 50% DGF risk was associated with a 2-fold increased risk of graft failure. This tool is useful for predicting DGF and long-term outcomes at the time of transplant. ©2010 The Authors Journal compilation©2010 The American Society of Transplantation and the American Society of Transplant Surgeons.

To determine the distribution of HIV-1 subtypes and the prevalence of transmitted drug resistance-associated mutations (TDRM) among persons newly diagnosed with HIV-1 infection in the United States. We used sequence data from Variant, Atypical, and Resistant HIV Surveillance (VARHS) collected from newly diagnosed persons in 10 states and 1 county health department in 2006. To evaluate TDRM, we used a mutation list for surveillance of TDRM appropriate for the primarily subtype B HIV epidemic in the United States. Sequences were obtained from 2030 of 10,860 persons newly diagnosed with HIV in 11 surveillance areas. Mutations associated with transmitted drug resistance occurred in 292 (14.6%) persons; TDRM associated with a specific drug class occurred in 156 (7.8%) for non-nucleoside reverse transcriptase inhibitors, 111 (5.6%) for nucleoside reverse transcriptase inhibitors and 90 (4.5%) for protease inhibitors. There were no significant differences in prevalence of TDRM by demographic characteristic. The HIV-1 subtype B was the most prevalent subtype occurring in 1922 (96.2%) persons; subtype C (1.3%) was the most prevalent non-B subtype. We presented a clade B-optimized mutation list for evaluating surveillance of TDRM in the United States and analyzed the largest collection of sequence data obtained from individuals newly diagnosed with HIV. The prevalence of TDRM in persons newly diagnosed with HIV is higher than in previous U.S. studies; however, this is not necessarily a significant trend. Continued reporting of sequence data for public health purposes from all sources will improve representativeness and accuracy in analyzing trends in transmitted drug resistance and genetic diversity.

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.
