CXCR4-tropic (X4) HIV-1 variants are associated with faster disease progression compared with CCR5-tropic variants; however, the mechanism for this is unclear. We measured T-cell activation in 120 individuals with primary HIV-1 infection. X4-utilizing variants, determined genotypically, were present in 8.3% of the participants and were associated with… (More)
The use of antiretroviral therapy as post-exposure prophylaxis against human immunodeficiency virus (HIV) is now routine following high-risk exposure to the HIV virus. This article summarizes the management of health care workers and others exposed to HIV in an occupational setting, and the evidence behind it.
OBJECTIVES The magnitude of HIV viral rebound following ART cessation has consequences for clinical outcome and onward transmission. We compared plasma viral load (pVL) rebound after stopping ART initiated in primary (PHI) and chronic HIV infection (CHI). DESIGN Two populations with protocol-indicated ART cessation from SPARTAC (PHI, n = 182) and SMART… (More)
Travellers engaging in sexual contact with a new partner abroad may be at high risk of acquiring a sexually transmitted infection. This review examines the impact of travel on sexual health and provides prevention, management and treatment recommendations to practising occupational health physicians.
Treatment of HIV-1 infection with antiretroviral therapy (ART) in the weeks following transmission may induce a state of 'post-treatment control' (PTC) in some patients, in whom viraemia remains undetectable when ART is stopped. Explaining PTC could help our understanding of the processes that maintain viral persistence. Here we show that immunological… (More)
PURPOSE OF REVIEW This review will discuss the role of antiretroviral therapy to treat primary HIV infection (PHI) as a strategy to prevent onward viral transmission. RECENT FINDINGS Novel technology has greatly enhanced the appreciation of the characteristics of recently transmitted HIV-1 variants. Recent primate data demonstrate marked enhanced… (More)
The objective of this study was to assess changes in the uptake of sexually transmitted infection (STI) screening resulting from implementation of a specific STI clinic for HIV-positive patients. An audit of STI screening in HIV-positive patients was undertaken before and after the establishment of the clinic. Significant increases in the number of patients… (More)
Sexually transmitted infections such as chlamydia, gonorrhoea, herpes simplex virus and syphilis commonly present with rectal symptoms. Recent outbreaks of lymphogranuloma venereum among homosexual men throughout Europe highlight the need to consider sexually transmitted infections in the differential diagnosis of proctitis. This article examines the… (More)
We describe three homosexual men presenting to the ear, nose and throat clinic with severe tonsillitis. All were subsequently diagnosed with secondary syphilis of the tonsil. Syphilis should be considered as a diagnosis in high risk patients presenting with tonsillar lesions, even in the absence of other classical features of the disease.
OBJECTIVE Inflammation and coagulation biomarkers interleukin (IL)-6 and D-dimer are predictive of all-cause mortality in chronic HIV-1 infection; however, their predictive value in individuals with recent infection has not been described. METHODS SPARTAC was a randomized controlled trial comparing three strategies of intervention in primary HIV-1… (More)
