A retrospective study of 55 HIV-1 seropositive African patients living
in the UK, seen between January 1986 and November 1993, showed a tota
l of 26 (47%) patients with AIDS. Thirty-one (56%) had symptomatic HIV
disease at the time of presentation of whom 19 (34.5%) had an AIDS de
fining condition. Tuberculosis was the most common AIDS defining illne
ss, accounting for 27% of all initial AIDS diagnoses, followed by Pneu
mocystis carinii pneumonia and oesophageal candidiasis in 19% each and
chronic mucocutaneous genital herpes in 15%. The mean CD4 count at th
e time of the first AIDS defining event was 91 x 10/mm(3) (range 4-320
x 10/mm(3)). The profile of AIDS defining illnesses was different to
published data of homosexual men and injecting drug users in the UK. T
his has practical implications when considering differential diagnoses
and screening as well as prophylaxis for opportunistic infections in
this group of patients.
