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)
As sequence data sets used for the investigation of pathogen transmission patterns increase in size, automated tools and standardized methods for cluster analysis have become necessary. We have developed an automated Cluster Picker which identifies monophyletic clades meeting user-input criteria for bootstrap support and maximum genetic distance within(More)
After an increase in the number of reported cases of Pneumocystis jirovecii pneumonia in England, we investigated data from 2000-2010 to verify the increase. We analyzed national databases for microbiological and clinical diagnoses of P. jirovecii pneumonia and associated deaths. We found that laboratory-confirmed cases in England had increased an average(More)
BACKGROUND There is interest in expanding ART to prevent HIV transmission, but in the group with the highest levels of ART use, men-who-have-sex-with-men (MSM), numbers of new infections diagnosed each year have not decreased as ARTcoverage has increased for reasons which remain unclear. METHODS We analysed data on the HIV-epidemic in MSM in the UK from a(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 Control of HIV transmission could be achievable through an expansion of HIV testing of at-risk populations together with ready access and adherence to antiretroviral therapy. To examine whether increases in testing rates and antiretroviral therapy coverage correspond to the control of HIV transmission, we estimated HIV incidence in men who have(More)
There are few data on the persistence of individual human immunodeficiency virus type 1 (HIV-1) transmitted drug resistance (TDR) mutations in the absence of selective drug pressure. We studied 313 patients in whom TDR mutations were detected at their first resistance test and who had a subsequent test performed while ART-naive. The rate at which mutations(More)
BACKGROUND Long-term regular clinic follow up is an important component of HIV care. We determined the frequency and characteristics of HIV-infected patients lost to follow up from a London HIV clinic, and factors associated with loss to all HIV follow up in the UK. METHODS We identified 1859 HIV-infected adults who had registered and attended a London(More)
OBJECTIVE To evaluate whether the prevalence of HIV-1 transmitted drug resistance has continued to decline in infections probably acquired within the United Kingdom. DESIGN Multicentre observational study. SETTING All UK public laboratories conducting tests for genotypic HIV resistance as a part of routine care. PARTICIPANTS 14,584 patients infected(More)
