Cohort event monitoring of patients treated for uncomplicated malaria with artemisinin-based combination therapies in selected hospitals and community pharmacies in Nigeria.

AIMS AND OBJECTIVES: The study was designed with the broad objective of determining the safety profile of artemisinin-based combination therapies amongst Nigerian population. PATIENTS AND METHODS: This was a cohort event monitoring (CEM) programme involving monitoring adverse events (AEs) in malaria patients treated with either artemether-lumefantrine (AL) or artesunate-amodiaquine (AA) in healthcare facilities in Nigeria. The study involved continuous enrolment of patients with malaria and treated with either AL or AA at the various sites until a total cohort of 600 patients were enrolled at each site. Patients were monitored from the onset of therapy, and on days 3 and 7 from the first day of treatment to identify AEs that may occur. RESULTS: A total of 6102 AEs were recorded in 10,259 patients monitored during the programme. Of 4896 patients who received AA, 4233 (86.5%) patients reported at least one AE while 1869 (34.8%) AEs out of 5363 patients who received AL were reported (P = 0.010). The predominant incidence of each specific AE reported in each group among the patients who received AA and AL includes body weakness 30.8%/7.5%, dizziness 10.3%/3.9%, restlessness 5.02/1.12%, vomiting 3.5/1.03% and drowsiness 3.1/1.5% for AA and AL, respectively. There were more AEs among patients with co-morbid conditions and patients in the younger age groups (9-<15 years), P = 0.000. CONCLUSIONS: Various types of AEs were seen and documented during the CEM programme. The findings suggested that the AA/AL monitored during this programme was generally safe and remarkably well tolerated among the Nigerian populations.

PREVALENCE, CO-PREVALENCE AND RISK FACTORS OF PULMONARY PARAGONIMIASIS AND PULMONARY TUBERCULOSIS IN NIGERIAN CHILDREN IN THE NIGER DELTA AREA.

BACKGROUND: Nigeria has the highest burden of paragonimiasis in Africa and it is also among the high burden countries with tuberculosis. The true prevalence of these reemerging diseases is unknown in the country. OBJECTIVE: To determine the prevalence and co-prevalence of thesere-emerging diseases among children in a rural Nigerian community. DESIGN: Descriptive cross-sectional study. SETTING: Ewang, a rural fishing community in Mbo Local government Area of Akwa Ibom State, Nigeria. SUBJECTS: Primary and secondary school children aged 5-18years living in Ewang village, Mbo Local government Area of Akwa Ibom State, Nigeria. RESULTS: A total of 204 children were examined: 91(44.6%) were males, while 113(55.4%) were females. Ten of the subjects were sputum positive for paragonimus eggs, giving an overall prevalence rate of 4.9%,while six children were sputum positive for pulmonary tuberculosis with a prevalence rate of 2.9%. There was no case of co-infection. The peak age prevalence of paragonimus ova-positive and Acid and Alcohol fast positive subjects was recorded in the five to nine year old age group with prevalence rate of 5.6% and7.4% respectively. There was a female preponderance among the paragonimus ova-positive subjects (90%) and the AAFB positive subjects (66.7%). CONCLUSIONS: The findings show that paragonimiasis is an emerging/re-emerging disease in southern Nigeria and further confirmed that the prevalence of tuberculosis is still on an upward rise.
