Abstract:
Malaria prevention in pregnancy especially in endemic areas has been greatly emphasized. This is especially so during the antenatal periods. Malaria prevention is important for reducing the problems of malaria in pregnancy. Early trimester miscarriages, preterm labours, anaemia in pregnancy, small for date babies and increased admissions into special care baby units are some of the problems encountered that are traceable to malaria infection. It is also noteworthy that some favourable antioxidants have been noted to help pregnant women enjoy and cope with their pregnancies. In that same way, it has also been noted that optimal levels of superoxide dismutase is equally necessary to help pregnant women enjoy uneventful pregnancies as well as stay free from some problems associated with malaria in pregnancy.
Objectives: We have comparatively and objectively assessed the plasma Levels of superoxide dismutase in Parturients on Intermittent Preventive Treatment with Sulphadoxine Pyrimethamine and their Controls at Current Confinements.
Method: This comparative study was conducted at the Obstetrics and Gynaecology Department of the Federal Medical Centre (FMC) Owerri, South East Nigeria. Owerri is widely known for its heavy malaria endemicity. Prior to participant recruitment, appropriate ethical clearance was applied for and obtained from the ethics committee of FMC Owerri. This enabled the commencement of the longitudinal recruitment of participants after due counseling and adequate informed consent involving both study groups. This bench-based research and cross-sectional descriptive study involved two hundred and ninety-six (296) consented participants. The participants were made to understand clearly the study protocol as well as satisfy the inclusion criteria for either the study (case) or control groups. Upon recruitment, participants were then followed up all throughout their entire antenatal course culminating in the delivery. The follow up enabled the collection of blood samples for the estimation of Superoxide Dimutase (SOD) plasma levels at delivery. The SOD levels were estimated using the Misra and Fridovich method, 1972. The ability of superoxide dismutase to inhibit the auto oxidation of adrenaline at pH 10.2 makes this reaction a basis for the SOD assay. Superoxide anion (O2) generated by the xanthine oxidase reaction is known to cause the oxidation of adrenaline to adrenochrome. The yield of adrenochrome produced per superoxide anion introduced increased with increasing pH and also with increasing concentration of adrenaline. These led to the proposal that auto oxidation of adrenaline proceeds by at least two distinct pathways, one of which is a free radical chain reaction involving superoxide radical and hence could be inhibited by SOD.
Data analysis: Data computation and analysis were done using the computer Software Package for Social Science (SPSS) version 20.0 (SPSS, Inc, 2007, Chicago). Important descriptive statistics (mean, standard deviation, range, percentages etc) were determined for continuous variables. P-value less than (<0.05) at 95% confidence interval was considered statistically significant.
Result: The mean serum level of superoxide dismutase (SOD) in the study group was 12.61 U/ml ± 3.105 while the minimum and maximum serum superoxide dismutase were 7 and 20 U/ml respectively. For their controls, the mean serum level of superoxide dismutase was 11.69 U/ml ± 2. 969. However, the minimum and maximum serum superoxide dismutase were 7 and 20 U/ml respectively. The difference was found to be statistically significant (p= 0.011) with odds ratio 1.12 (CI of 95% 1.024-1.193).
