Superior outcomes in HIV-positive kidney transplant patients compared with HCV-infected or HIV/HCV-coinfected recipients.

ABSTRACT: The prerequisite for an 'undetectable' HIV viral load has restricted access to transplantation for HIV-infected kidney recipients. However, HCV-infected recipients, owing to the historic limitations of HCV therapy in patients with renal disease, are commonly viremic at transplant and have universal access. To compare the effect of HIV, HCV, and HIV/HCV coinfection on kidney transplant patient and allograft outcomes, we performed a retrospective study of kidney recipients transplanted from January 1996 through December 2013. In multivariable analysis, patient (hazard ratio 0.90, 95% confidence interval 0.66-1.24) and allograft survival (0.60, 40-0.88) in 492 HIV patients did not differ significantly from the 117,791 patient-uninfected reference group. This was superior to outcomes in both the 5605 patient HCV group for death (1.44, 1.33-1.56) and graft loss (1.43, 1.31-1.56), as well as the 147 patient HIV/HCV coinfected group for death (2.26, 1.45-3.52) and graft loss (2.59, 1.60-4.19). HIV infection did not adversely affect recipient or allograft survival and was associated with superior outcomes compared with both HCV infection and HIV/HCV coinfection in this population. Thus, pretransplant viral eradication and/or immediate posttransplant eradication should be studied as potential strategies to improve posttransplant outcomes in HCV-infected kidney recipients.

Project description:BackgroundThe measurement of hepatitis C virus core antigen (HCV-coreAg) has been shown to be an indicator of active HCV infection. The aim of the present study was 1) to investigate the stability and effectiveness of HCV-coreAg and HCV-RNA quantification in HCV infection with or without HIV-1 coinfection, 2) to explore the association between the HCV-coreAg/HCV-RNA (Ag/RNA) ratio and the immune status in chronic HCV/HIV-1-coinfected patients.MethodsA longitudinal investigation comprised of 227 HCV-monoinfected (n = 129) and HCV/HIV-1-coinfected (n = 98) patients was initiated in August 2009, and 139 (73 with HCV monoinfection and 66 with HCV/HIV-1 coinfection) were followed up in August 2012. Both HCV core antigen and HCV RNA quantification were determined on this cryopreserved plasma. HCV core antigen and HCV RNA quantification were performed subsequently. In addition, an in vitro experiment investigating the possibility of degradation of HCV components (core antigen and RNA) were conducted.ResultsSignificant and stable correlations (p < 0.001) were observed both in chronic HCV-monoinfected and HCV/HIV-1-coinfected patients over the 3-year observation. Coinfected patients with immunocompromised condition had a significantly higher (p < 0.05) Ag/RNA ratios than those patients with immunocompetent condition both at two time points (2009 and 2012). Moreover, the Ag/RNA ratios were negatively correlated with CD4+ T-cell counts (p < 0.001). An in vitro experiment investigated the possibility of the slower degradation of HCV particles under HIV-related immunocompromised condition was conducted and the data demonstrated that the Ag/RNA ratios were significantly higher in HIV-1-positive plasma than in healthy plasma (p = 0.005) in this study.ConclusionsOur longitudinal study indicated that the HCV-coreAg presented comparable dynamics over time as HCV RNA in chronic HCV-infected patients. Meanwhile, the HCV-coreAg/HCV-RNA ratio was closely associated with immune status in HCV/HIV-1-coinfected patients.
