Some Haematological Parameters among Urinary Schistosomiasis-Malaria Coinfected Children in Suburb of Malentouen Health District, West Region Cameroon

Background: Schistosomiasis and Malaria are among the most prevalent afflictions of humans who live in areas of poverty in the developing world. The present study was aimed at determining the socio demographic characteristics and prevalence of schistosomiasis and malaria in children living in Suburb of Malentouen Health District and analyzing the effect of co-infection on haemoglobin level, mean corpuscular volume and platelet count.

Methods: Questionnaires were distributed to parents or guardians of children attending public primary school in the area. A total of 429 pupils aged 6-15 years old were screened for urinary schistosomiasis and 228 out of the 429 were tested for. Prevalences of the two parasites were calculated; Haemoglobin level, Mean Corpuscular Volume and platelets count of the 228 participants were recorded.

Results: The prevalence of malaria was 26.75%, where as that of schistosomiasis was 43.82%. 31(13.60%) of the participants were co-infected with the two parasites. Mean haemoglobin level obtained was 11.01± 1.19 G/dL, that of MCV was 84.50±5.31/fl and the mean platelet count was 255.13±96.99/µl. In malaria single infected and co-infected participants, low haemoglobin level (c2 = 50.315, p = .000), low MCV (c2 = 27.448, p = .000) and low platelets count (c2 = 37.253, p = .000) were observed with significant variations.

Conclusions: The three haematological parameters analysed in this study (Hb, MCV, Platelets count), showed low level or amount in malaria and malaria-schistosomiasis infected participants. Moreover, thrombocytopenia in children in this endemic area may be useful as supportive diagnostic criteria for malaria in case with low level of parasite number.
