OBJECTIVES The aim of this study was to investigate the frequency of CYP2B6 polymorphisms (according to ethnicity) and the influence of heterozygosity and homozygosity on plasma concentrations of efavirenz and nevirapine. METHODS Following written informed consent, 225 Caucasians and 146 Blacks were recruited from the German Competence Network for(More)
The "D drug" HIV reverse-transcriptase inhibitors zalcitabine, didanosine, and stavudine are relatively strong inhibitors of polymerase-gamma compared with the "non-D drugs" zidovudine, lamivudine, and abacavir. D drugs deplete mitochondrial DNA (mtDNA) in cultured hepatocytes. This mtDNA depletion is associated with an increased in vitro production of(More)
In the developed world, the majority of new and existing hepatitis C virus (HCV) infections occur among people who inject drugs (PWID). The burden of HCV-related liver disease in this group is increasing, but treatment uptake among PWID remains low. Among PWID, there are a number of barriers to care that should be considered and systematically addressed,(More)
BACKGROUND Hepatitis B coinfection is common in HIV-positive individuals and as antiretroviral therapy has made death due to AIDS less common, hepatitis has become increasingly important. Several drugs are available to treat hepatitis B. The most potent and the one with the lowest risk of resistance appears to be tenofovir (TDF). However there are several(More)
BACKGROUND & AIMS There is increasing interest in identifying patients with chronic hepatitis C genotype 2 or 3 infection in whom it is possible to lower the burden of therapy while retaining high levels of efficacy. METHODS Treatment-naive patients with chronic hepatitis C genotype 2/3 infection were randomized to receive peginterferon alfa-2b(More)
Fibrosis progression after acute hepatitis C virus (HCV) infection in human immunodeficiency virus (HIV)-infected patients with follow-up >9 months became similar to reported rates from studies in chronic HIV/HCV coinfection, as measured with transient elastometry. The duration of follow-up and serum alanine transaminase correlated with liver stiffness, and(More)
BACKGROUND Persons infected with human immunodeficiency virus (HIV) have increased rates of coronary artery disease (CAD). The relative contribution of genetic background, HIV-related factors, antiretroviral medications, and traditional risk factors to CAD has not been fully evaluated in the setting of HIV infection. METHODS In the general population, 23(More)
Motor tests comprising the analysis of postural tremor, most rapid voluntary alternating index finger movements (MRAM) and the rise time of most rapid index finger extensions (CT) allow us to quantify HIV-associated minor motor deficits electrophysiologically. The electrophysiological results in 57 HIV-positive individuals who acquired HIV infection by(More)
HBsAg clearance is associated with clinical cure of chronic hepatitis B virus (HBV) infection. Quantification of HBsAg may help to predict HBsAg clearance during the natural course of HBV infection and during antiviral therapy. Most studies investigating quantitative HBsAg were performed in HBV mono-infected patients. However, the immune status is(More)
BACKGROUND Previous trials have often defined genotype 2 and 3 patients as an "easy to treat" group and guidelines recommend similar management. AIMS The present study looks for differences between the two genotypes and analyzes predictive factors for SVR. METHODS Prospective, community-based cohort study involving 421 physicians throughout Germany. The(More)
