Prevalence, predictors, and perceived susceptibility to placental malaria parasitemia among pregnant women in a tertiary hospital in South-Western Nigeria

Objective: Is to determine the prevalence and predictors of placental malaria among pregnant women.Methodology: The study was cross-sectional in design. It was carried out over six months. We administered Pretested questionnaire to 300 eligible subjects. The researchers took maternal peripheral blood for malaria parasites while cord and placental blood sample at delivery for neonatal packed cell volume (PCV) and Malaria parasite. Data were analyzed using STATA 10.Result: One hundred and forty-four (48%) participants had placental malaria parasitemia, while 173 (57.7%) had peripheral malaria parasitemia. Maternal age less than 20 years (P=0.008), low parity, and hemoglobin type AA (P=0.002) were significantly associated with a higher prevalence of placental parasitemia. Maternal secondary and tertiary education (P=0.013), perceived susceptibility to placental malaria and IPT use (p=0.014) were significantly associated with lower prevalence.Conclusion: This study has shown that placental parasitemia is a significant problem in pregnancy as it is strongly associated with certain maternal factors. There is the need to intensify control efforts aimed at reducing malaria in pregnancy in Nigeria, and mothers with increased risk factors should receive more focused attention. Keywords: Prevalence, risk factors, placental malaria, pregnanc

Seroprevalence of syphilis among blood donors in Ilorin

Background: One of the greatest values of serological test for syphilis is as a surrogate marker for lifestyle known to be associated with high risk of HIV and HCV infections. This study was designed to determine the prevalence of syphilis among blood donors in Ilorin and also the relationship between seropositivity and lifestyle known to be associated with high risk for HIV and Hepatitis infection.Method: This was a hospital based cross sectional study involving 350 consenting blood donors. The socio-demographic details (e.g., age, sex, occupation, risk behavior etc) were obtained using a structured questionnaire designed for the study. Screening for syphilis was carried out using the DiaSpot Rapid Diagnostic Test kit (DS 401- Syphilis test strips; lot: SYP2070028) according to the manufacturer's (Sam Tech Diagnostics) instructions.Result: The seroprevalence of syphilis among the blood donors was 1.1%. None of the seropositive donors was a homosexual, commercial sex worker or intravenous drug user. None of them had history of blood transfusion. Only one out of the 4 seropositive donors engaged in extramarital sex.Conclusion: The seroprevalence of syphilis among blood donors in Ilorin was low and therefore the relationship between syphilis seropositivity and high risk lifestyle could not be determined. A prospective study design where cases and controls are appropriately matched to exclude confounders would be more appropriate. The relationship of syphilis seropositivity and high risk lifestyle can therefore be better studied among patients attending Sexually Transmitted Infection clinic and using seronegative patients as controls.Keywords: syphilis, blood donors, risky lifestyl

Psychotropic Medications and QTc Parameters in a Nigerian Cohort

Aims: Evidence is increasing to indicate that individuals with mental illness may be at risk of premature death. We studied the prevalence of QTc prolongation, QT dispersion (QTd) and cardiac arrhythmias in patients on psychotropic drugs. Study Design: Cross-sectional study. Place and Duration of Study: Department of Medicine and Department of Behavioral Sciences, University of Ilorin Teaching Hospital, Nigeria Between Januaryand June 2010. Methodology: One hundred and ninety-one consecutive patients on psychotropic medications with 121 controls were studied. All the subjects had detailed clinical examination and resting electrocardiogram (ECG) at 25mm/sec. QTc was determined using Bazett formula and QTd by subtracting shortest from longest QTc in 12-lead ECG. Results: Mean QTc of the patients (450±46msc) was longer (p=0.0001) than that of the controls (390±27msc) but mean QTd was similar (p=0.13) in both groups. QTc was prolonged in 68(35.6%) patients compared to 11(9.1%) controls, p=0.0001. LVH, arrhythmias and abnormal T-wave morphology occurred more (p=0.01, 0.01 and 0.001 respectively) in the patients than controls. Age, duration of treatment and total daily doses of antipsychotics were independent predictors of QTc. Cardiac arrhythmias were seen in 24.1% of the patients but none had ventricular arrhythmias. Conclusion: Psychotropic drug use is a risk factor for QTc prolongation and cardiac arrhythmias. We suggest periodic electrocardiography, discourage polypharmacy and recommend drug holiday in stable patients
