BACKGROUND Abacavir/lamivudine and tenofovir/emtricitabine fixed-dose combinations are commonly used first-line antiretroviral therapies, yet few studies have comprehensively compared their safety profiles. METHODS Forty-eight-week data are presented from this multicenter, randomized, open-label study comparing the safety profiles of abacavir/lamivudine(More)
Protective immunity against pulmonary tuberculosis (TB) is characterized by the formation in the lungs of granulomas consisting of macrophages and activated T cells producing tumor necrosis factor alpha and gamma interferon, both required for the activation of the phagocytes. In 90% of immunocompetent humans, this response controls the infection. To(More)
OBJECTIVES To estimate life expectancy for people with HIV undergoing treatment compared with life expectancy in the general population and to assess the impact on life expectancy of late treatment, defined as CD4 count <200 cells/mm(3) at start of antiretroviral therapy. DESIGN Cohort study. SETTING Outpatient HIV clinics throughout the United Kingdom.(More)
OBJECTIVE(S) To identify factors (including exposure to specific antiretroviral drugs) associated with severe vitamin D deficiency (VDD) in HIV-infected individuals and to explore the effects of severe VDD and antiretroviral drug exposure on serum alkaline phosphatase (ALP) as surrogate marker of bone turnover. DESIGN Cross-sectional survey of vitamin D(More)
OBJECTIVES To evaluate the safety and efficacy of the novel tenofovir prodrug, tenofovir alafenamide (TAF), as part of a single-tablet regimen (STR) for the initial treatment of HIV-1 infection. DESIGN Phase 2, randomized, double-blind, double-dummy, multicenter, active-controlled study. METHODS Antiretroviral naive adults with HIV-1 RNA ≥5000 copies(More)
OBJECTIVES The aim of the study was to investigate the prevalence and aetiology of chronic kidney disease (CKD) and trends in estimated glomerular filtration rate (eGFR) in HIV-infected patients. METHODS Ascertainment and review of CKD cases among patients attending King's College and Brighton Hospitals, UK were carried out. CKD was defined as eGFR <60(More)
BACKGROUND Tenofovir disoproxil fumarate can cause renal and bone toxic effects related to high plasma tenofovir concentrations. Tenofovir alafenamide is a novel tenofovir prodrug with a 90% reduction in plasma tenofovir concentrations. Tenofovir alafenamide-containing regimens can have improved renal and bone safety compared with tenofovir disoproxil(More)
OBJECTIVE The objective of this study is to estimate life expectancies of HIV-positive patients conditional on response to antiretroviral therapy (ART). METHODS Patients aged more than 20 years who started ART during 2000-2010 (excluding IDU) in HIV clinics contributing to the UK CHIC Study were followed for mortality until 2012. We determined the latest(More)
BACKGROUND The clinical epidemiology of acute renal failure (ARF) in human immunodeficiency virus (HIV)-infected patients remains poorly defined. METHODS We conducted a retrospective analysis of patients who developed ARF while attending King's College Hospital (London, United Kingdom) during January 1998-December 2005. Serum creatinine level and(More)
Pathogenetic processes that facilitate the entry, replication, and persistence of Mycobacterium tuberculosis (MTB) in the mammalian host likely include the regulated expression of specific sets of genes at different stages of infection. Identification of genes that are differentially expressed in vivo would provide insights into host-pathogen interactions(More)
