Postmortem neuropathologic reports for a consecutive series of 436 HIV-seropositive patients who died between 1985 and 1999 were matched with clinical data for 371 of them. Cases were divided into four groups depending on the date of death. The chosen time periods reflected the type of antiretroviral therapy available: before 1987 (before zidovudine);(More)
OBJECTIVE There is controversy over whether or not chronic HIV infection contributes to atherosclerosis. We investigated the relationship between HIV infection, antiretroviral medication and ultrasound evidence of early atherosclerosis in the context of vascular risk factors. DESIGN A case-control design with 292 HIV-positive subjects and 1168 age- and(More)
To investigate if possible mitochondrial injury can be found in adipose tissue of nucleoside analogue reverse transcriptase inhibitor (NRTI)-treated patients, subcutaneous fat was taken from the buttocks of 24 HIV-positive patients and 8 HIV-negative controls. The content of mitochondrial DNA (mtDNA) was quantified using a Southern blot technique. Fat(More)
BACKGROUND The safety of interrupting maintenance therapy for previous opportunistic infections other than Pneumocystis carinii pneumonia among patients with HIV infection who respond to potent antiretroviral therapy has not been well documented. OBJECTIVE To assess the safety of interrupting maintenance therapy for cytomegalovirus (CMV) end-organ(More)
UNLABELLED Chronic kidney disease (CKD) is an important cause of morbidity and mortality in HIV-positive individuals. Hepatitis C (HCV) co-infection has been associated with increased risk of CKD, but prior studies lack information on potential mechanisms. We evaluated the association between HCV or hepatitis B (HBV) co-infection and progressive CKD among(More)
OBJECTIVES Renal disease is a common and serious complication in HIV-infected patients. METHODS A 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:(More)
BACKGROUND To determine the rate of seroconversion after 2 doses of a novel split virion, inactivated, adjuvanted pandemic H1N1 influenza vaccine (A/California/7/2009) in human immunodeficiency virus type 1 (HIV-1)-infected patients ( NCT01017172). METHODS Diagnostic study of adult HIV-1-infected patients scheduled for H1N1 influenza A(More)
To evaluate the treatment outcome of antiretroviral therapy, depending on the use and utility of a concept of resistance-guided switch, patients from the Frankfurt HIV cohort have been followed for 24 weeks. If available, prior resistance data have been evaluated and patients were grouped into their expected viral response. The data of 354 patients were(More)
BACKGROUND Several studies have shown beneficial effects of recombinant human growth hormone (r-hGH) in reducing visceral adipose tissue (VAT) in HIV-1-infected patients with lipodystrophy. METHODS Patients were randomized to r-hGH 4 mg daily (group A) or three times per week (group B) over 12 weeks, followed by a 2 mg daily maintenance dose for 12 weeks.(More)
BACKGROUND With increasing life spans of HIV-infected individuals under highly active antiretroviral therapy, long-term consequences of the chronic infection and antiretroviral treatment are becoming more prevalent. Data on prevalence and consequences of hypertension are limited, but recent studies suggest that HIV-infected individuals are at a higher risk(More)
