Effects of sulphadoxine-pyrimethamine on maternal, neonatal and placental malaria in Port Harcourt, Rivers State, Nigeria
Abstract
Background & objectives: The utilization of Intermittent Preventive Treatment (sulphadoxine-pyrimethamine) in pregnancy (IPTp-SP) for combating malaria has indicated control over adverse birth outcomes and has been recommended for use by pregnant women. The aim of this study was to determine the effectiveness of IPTp-SP on maternal, neonatal and placental malaria in Port Harcourt, Nigeria. Methods: 316 samples of maternal peripheral blood (MPB), placental blood (PLB), neonatal cord blood (NCB) and placental tissue (PT) were collected each from consenting mothers. Blood samples were processed and stained by the Giemsa method. Placental tissues were processed and stained in haematoxylin. Examination of samples for malaria parasitaemia was carried out using standard parasitological methods. Demography of participants was collected through questionnaires and from ante natal care (ANC) records. Results: Overall prevalence of 74 (23.42%) was recorded. Age-related prevalence indicated that ≤ 20 years, 9 (56.25%) had the highest prevalence followed by 21–30 years (23.48%), and ≥41 years (16.67%) (p 0.05). The prevalence in PLB and PT revealed that SP-users had a lower prevalence in PLB, 31 (15.73%) and PT, 12 (6.09%) while non-users recorded a higher prevalence 48 (40.33%) in PLB and 21 (17.65%) in PT (P<0.05). Interpretation & conclusion: The utilization of IPTp-SP is seen to significantly reduce the occurrence of malaria in pregnancy, placental tissue and in neonates thereby helping in improving birth outcomes.
