Rapid onset and progression of myelopathy following an STI: a case for screening?

Human T lymphotropic virus type 1 (HTLV-1) is recognised as an STI with serious manifestations of the disease in approximately 10% of those infected. This case report is the first to describe the short interval from sexual acquisition of HTLV-1 to the onset of HTLV-1-associated myelopathy and rapid progression to spastic paraparesis. The number of adult infections in the UK per annum is unknown, but surveillance data indicate that around 30% of newly diagnosed infections are occurring in persons born in the UK, rather than in migrants from HTLV-1-endemic regions.

Differential adipose tissue gene expression profiles in abacavir treated patients that may contribute to the understanding of cardiovascular risk: a microarray study.

Objective: To compare changes in gene expression by microarray from subcutaneous adipose tissue from HIV treatment naïve patients treated with efavirenz based regimens containing abacavir (ABC), tenofovir (TDF) or zidovidine (AZT).

Design: Subcutaneous fat biopsies were obtained before, at 6- and 18-24-months after treatment, and from HIV negative controls. Groups were age, ethnicity, weight, biochemical profile, and pre-treatment CD4 count matched.

Evidence for a shift to anaerobic metabolism in adipose tissue in efavirenz-containing regimens for HIV with different nucleoside backbones.

Background: Antiretroviral (ARV) treatment has been associated with abnormalities in lipid and mitochondrial metabolism. We compared patterns of gene expression in the subcutaneous adipose tissue (SAT) of HIV-positive subjects before and after 18-24 months of ARV therapy with HIV-negative controls.

Methods: HIV patients naive to ARV were randomized to receive zidovudine (AZT), lamivudine (3TC) with efavirenz (EFV) or tenofovir disoproxil fumarate (TDF) with emtricitabine (FTC) and EFV.

Adipocyte differentiation, mitochondrial gene expression and fat distribution: differences between zidovudine and tenofovir after 6 months.

Background: Abnormal lipid metabolism and cell oxidative mechanisms are reported in patients on antiretroviral treatment. We compared the expression of several key adipocyte genes in HIV-infected patients randomized to antiretroviral regimens containing zidovudine (AZT) or tenofovir disoproxil fumarate (TDF).

Methods: Subcutaneous fat was sampled from 32 HIV-positive treatment-naive patients before and 6 months after randomization to AZT/lamivudine/efavirenz (n=15) or TDF/emtricitabine/efavirenz (n=17) plus 15 HIV-negative matched controls.

An unusual vulval lesion in an HIV-infected woman.

This is the case of a black African woman who presented with three distinct episodes of herpes simplex virus (HSV) infection unresponsive to first-line therapy. Clinical and virological resistance to aciclovir therapy was demonstrated, and although the first two episodes manifested as the deep ulceration often associated with HIV/HSV coinfection, the third was an atypical hypertrophic lesion. This is despite her CD4 count being persistently above 300 and there being no previous diagnosis of AIDS.

Managing genital chlamydial infection: the effects of ethnic origin and method of follow-up.

We assessed if ethnicity and method of follow-up were associated with differences in the number of patients and the number of partners successfully treated for genital chlamydial infection. This was done by retrospectively reviewing the first 400 cases of genital chlamydia diagnosed between February and June 2001 who had a traditional clinic follow-up and the first 400 cases from the same period in 2002 when the telephone follow-up was used. The telephone follow-up appointment system, when compared to a traditional clinic follow-up appointment system, eliminated differences between Black and White ethnic groups in the numbers of patients and partners satisfactorily treated.
