Respiratory problems like Pneumocystic carinni and Pulmonary tuberculosis (PTB) are among the common opportunistic infections in patients with HIV/AIDS. The risk of acquiring Mycobacterium tuberculosis in a community becomes greater with increase in the number of HIV positive persons with active tuberculosis. This study was carried out to determine the magnitude of HIV infection among PTB patients in different parts of Nigeria as part of the year 2000 national HIV surveillance programme. Blood samples were collected on blotting paper from a total of 2826 individuals attending TB clinics between 1st of September and 1st November, 2000. Samples were collected from patients with confirmed PTB from 12 states in the 6 geopolitical/health zone (2 states/zone) of Nigeria as part of high risk sentinel population groups. Samples were tested for the presence of HIV antibodies using commercial ELISA (Genescreen HIV-1/2, Sanofi Pasteur, Paris). All initially reactive samples were retested with a rapid EIA (Gene II, Sanofi Pasteur, Paris) according to the WHO recommendations (option II). HIV Prevalence in the states varied from 4.2% in Oyo to 35.1% in Benue States with a median prevalence of 17.0%. HIV Prevalence increased with age to a peak of 23.9% among PTB patients 30-39 years and then declined progressively to 12.8% among those 60 years and above. A relatively high HIV infection rate (13.8%) was found among the young adolescent age group 10-19 years. There was no significant difference in the rate among male and female PTB patients tested. Comparison with results of previous HIV sero-surveys shows a steady increase in HIV prevalence among PTB patients over the years. The high prevalence of HIV among young PTB patients aged 10-19 years in this study is worrisome and must be noted for intervention.
Human immunodeficiency seropositivity among mother-child pairs in South west Nigeria: a community-based survey.
(2001) Omotunde, O. O.; Olaleye, D. O.; Saliu, I.; Odaibo, N. G.; Adeyemo, A. A.
A community based survey to determine the prevelence of human immunodeficiency infection in Nigeira women and children in south western Nigeria is reported. A multi-stage cluster random sampling procedure was used to select mother-child pairs from 35 enumeration areas in south western Nigeria. The final study sample consisted of 460 mothers and 476 children (including 16 sets of twins). A commercially available recombinant antigen-based ELISA method was used to test for HIV-I and HIV-2 anti-body in sera and western blotting was used as a confirmatory test for initially reactive samples. Only one mother-child pair (out of 460 mother-child pairs) was found to the positive for HIV antibody giving a mother-child concordance for HIV infection of 0.22%. Antibody to either HIV-1 of HIV-2 was detected in 3.8% (18/476) of the children's sera and in 4.3% (20/460) of mothers sera. HIV-1 reactivity was commoner than HIV-2 reactivity (2.9% versus 0.8% among children and 2.8% versus 1.5% among mothers). There were many more positive samples in the rural than in urban areas among children (7.1% versus 1.1%) and also among mothers (6.8% versus 2.4%),(p<0.001). Ths, HIV infection appears to be a real problem in south western Nigeria. The lack of concordance between mother-child sera suggests that vertical transmission may not be a major route of tansmission of HIV infection in children in South western Nigeria. It suggested that certain high risk practices(such as the re-use of unsterillised hypodermic needles for injections and surgical knives in local scarfication) which are common practices, especially in rural areas, need to be investigated as potential major modes of transmission of the infection. Control programmes need to take note of these finidngs in order to adequatly paln comprhensive health education which will cover the whole population, invluding children.
