A study of chest infections in HIV seropositive patients in Kuala Lumpur.
A retrospective study of 144 adults with HIV infection was conducted to investigate the prevalence of upper and lower respiratory tract infections (URTIs and LRTIs). The patients were divided into two groups: those with acquired HIV through intravenous drug abuse (IVDA), and those who had acquired HIV through 'other' risk behaviours. LRTIs were more prevalent than URTIs overall, and LRTIs were significantly more common (p < 0.001) in IVDAs than in the other-risk group. Tuberculosis (40%) and bacterial pneumonias (33%) comprised the majority of LRTIs among IVDAs, while Pneumocystis carinii pneumonia (40%) was the commonest LRTI in the other-risk group. Analysis of CD4 T-lymphocyte counts indicated that HIV-seropositive IVDAs are at greater risk of developing chest infections at higher CD4 counts than other-risk patients. The IVDAs were also found to have a much higher rate of co-infection with hepatitis C and B, which may be a factor accelerating the progression from HIV infection to AIDS. The mean time averaged for the two groups from known seroconversion to development of respiratory tract infection is only 1.37 years, which suggests HIV-infected patients are presenting late for treatment in Malaysia.
