Abstract
Summary
We report a case of HIV-1 infection transmission caused by a fist fight between brothers. A 30-year-old Caucasian UK resident man developed ‘flu-like illness with symptoms of lethargy and weakness. Persistent lymphadenopathy six months later lead to HIV antibody testing, which was positive. Of note, his 37-year-old brother, who was HIV antibody-positive since August 2000, was taking HAART (combivir and nevaripine) with CD4 350 × 106/L (16%) with viral load 4800 copies/mL (log 2.58). A bloody fight had occurred between them four weeks prior to onset of symptoms. Phylogenetic analysis was undertaken. Analysis of the pol gene region indicated that samples from both brothers belonged to the subtype C clade of HIV-1, and that the sequences were closely related to one another. Exposure risk data are extremely useful in helping counsel patients prior to HIV-testing but, as this case illustrates, does not cover all situations.
