title: Seroprevalence of toxoplasmosis among AIDS patients in Hospital Kuala Lumpur, 2001.
abstract: Four hundred and six AIDS patients were recruited in this retrospective study. The seroprevalence of toxoplasmosis among 406 AIDS patients was 208 (51.2%). Their age ranged from 17 to 74 years with a median of 35 years. The majority of patients were males 172 (82.6%), Malays 99 (47.5%), single 109 (52.4%), unemployed 99 (47.6%) and heterosexual with commercial sex workers (CSW) 97 (46.6%) as the risk marker to HIV infection. Thirty-one (14.9%) of 208 AIDS-related toxoplasmosis were diagnosed as active toxoplasmic encephalitis. The most common clinical manifestation was headache (67.7%). The CT scan findings showed most lesions to be multiple (87.5%), hypodense (66.7%), and in frontal region (41.7%). Twenty-two (71%) patients had chronic (latent) Toxoplasma infection as evidenced by seropositivity for anti-Toxoplasma (IgG) antibody. They were statistically significant in the association between CD4 count and toxoplasmic encephalitis (P = 0.019; OR = 2.6; 95% CI = 1.14-6.02). After the initial six weeks of anti-TE therapy, relapsing toxoplasmic encephalitis was detected in 9.7% in this study.
