Background We examined specific causes of mortality in human immunodeficiency virus type 1 (HIV-1)–infected patients who initiated antiretroviral therapy (ART) in Europe and North America from 1996 through 2006, and we quantified associations of prognostic factors with cause-specific mortality. Methods We retrospectively classified all deaths among 39,272 patients enrolled in 13 HIV-1 cohorts (154,667 person years of follow-up) into the categories specified in the Cause of Death (CoDe) project protocol. Results In 1597 (85%) of 1876 deaths, a definitive cause of death could be assigned. Among these, 792 deaths (49.5%) were AIDS related, followed by non-AIDS malignancies (189; 11.8%), non-AIDS infections (131; 8.2%), violence- and/or drug-related causes (124; 7.7%), liver disease (113; 7.0%), and cardiovascular disease (103; 6.5%). Rates of AIDS-related death (hazard ratio [HR] per 100 cell decrease, 1.43; 95% confidence interval [CI], 1.34–1.53) and death from renal failure (HR, 1.73; 95% CI, 1.18–2.55) were strongly inversely related to CD4 count at initiation of ART, whereas rates of death attributable to AIDS (HR for viral load >5 vs ≤5 log copies/mL, 1.31; 95% CI, 1.12–1.53), infection (HR, 1.85; 95% CI, 1.25–2.73), cardiovascular (HR, 1.54; 95% CI, 1.05–2.27), and respiratory causes (HR, 3.62; 95% CI, 1.30–10.09) were higher in patients with baseline viral load >5 log copies/mL than in other patients. Rates of each cause of death were higher in patients with presumed transmission via injection drug use than in other patients, with marked increases in rates of liver-related (HR for injection drug use vs non–injection drug use, 6.06; 95% CI, 4.03–9.09) and respiratory tract–related (HR, 4.94; 95% CI, 1.96–12.45) mortality. The proportion of deaths classified as AIDS related decreased with increasing duration of ART. Conclusions Important contributors to non-AIDS mortality in treated HIV-1–infected individuals must be addressed if decreases in mortality rates are to continue.

ObjectivesRenal disease is a common and serious complication in HIV-infected patients. MethodsA retrospective cohort analysis for the period 1989-2010 was carried out to determine the prevalence, incidence and risk factors for end-stage renal disease (ESRD). ESRD was defined as initiation of renal replacement therapy. Three time periods were defined: 1989-1996 [pre-highly active antiretroviral therapy (HAART)], 1997 (early HAART) and 2004. ResultsData for 9198 patients [78.2% male; 88.9% Caucasian; cumulative observation time 68 084 patient-years (PY)] were analysed. ESRD was newly diagnosed in 35 patients (0.38%). Risk factors for ESRD were Black ethnicity [relative risk (RR) 5.1; 95% confidence interval (CI) 2.3-10.3; P < 0.0001], injecting drug use (IDU) (RR 2.3; 95% CI 1.1-4.6; P = 0.02) and hepatitis C virus (HCV) coinfection (RR 2.2; 95% CI 1.1-4.2; P = 0.03). The incidence of ESRD decreased in Black patients over the three time periods [from 788.8 to 130.5 and 164.1 per 100 000 PY of follow-up (PYFU), respectively], but increased in Caucasian patients (from 29.9 to 41.0 and 43.4 per 100 000 PYFU, respectively). The prevalence of ESRD increased over time and reached 1.9 per 1000 patients in 2010. Mortality for patients with ESRD decreased nonsignificantly from period 1 to 2 (RR 0.72; P = 0.52), but significantly from period 1 to 3 (RR 0.24; P = 0.006), whereas for patients without ESRD mortality decreased significantly for all comparisons. ESRD was associated with a high overall mortality (RR 9.9; 95% CI 6.3-14.5; P < 0.0001). ConclusionAs a result of longer survival, the prevalence of ESRD is increasing but remains associated with a high mortality. The incidence of ESRD declined in Black but not in Caucasian patients. IDU and HCV were identified as additional risk factors for the development of ESRD.Keywords: chronic kidney disease, haemodialysis, HIV-associated nephropathy, renal failure, renal replacement therapy Accepted 18 July 2012 IntroductionThe prevention and treatment of cardiovascular, liver and kidney diseases have increasingly been the focus of attention in attempts to reduce the morbidity and mortality of HIV-infected individuals [1]. In the USA, HIV-associated ESRD has become epidemic among Black patients [11,12]. Black individuals are more prone to kidney disease than any other ethnic group in the general [13,14] and HIV-infected populations, possibly as a consequence of predisposing genetic polymorphisms [15]. The risk of ESRD in Black HIV-infected individuals has been reported to be three-to six-fold higher than in Caucasian HIV-infected patients [7,16,17], reflecting the susceptibility of Black patients to develop HIVAN. The introduction of highly active antiretroviral therapy (HAART) has reduced the incidence of HIVAN and ESRD among Black patients [18][19][20], but the prevalence of ESRD is projected to further increase [11,12]. Earlier studies, mainly from the USA, concluded that, almost exclusively in Black patients, HIVAN is one of the major causes of ESRD [6,21,22], but histologica...

Among HIV-infected patients, the rate of seroconversion after the first dose of an adjuvanted H1N1 influenza A vaccine was 68% and increased to 92% after a second doses.

Seroconversion after one dose of a split virion, inactivated, adjuvanted pandemic H1N1 influenza vaccine of HIV-infected patients was 69%. Studies to investigate whether a second dose of the vaccine will increase seroconversion rate are needed.
