Parasitologic Assessment of Two-Dose and Monthly Intermittent Preventive Treatment of Malaria during Pregnancy with Sulphadoxine-Pyrimethamine (IPTP-SP)‎ in Lagos, Nigeria

الملخص EN

Intermittent preventive treatment of malaria with sulphadoxine-pyrimethamine (IPTP-SP) is a key strategy in the control of malaria in pregnancy.

However, reports of increasing level of resistance to SP using nonpregnant populations have made it imperative for the continuous monitoring of the efficacy of SP in pregnant women.

This study assessed using microscopy, monthly dosing and the standard two-dose regimen among 259 pregnant women attending antenatal clinics in Lagos, Nigeria that consented 122 in the two-dose arm (Arm A) and 137 in the monthly dose arm (Arm B).

Baseline parasitaemia in the two groups was 5 (4.1%) and 3 (2.2%) in Arms A and B, respectively.

Few of the women developed parasitaemia after the initial SP dose in Arms A 4 (3.3%) and B 2 (1.5%).

However, none of the women had malaria infection after the second dose in both Arms.

Although IPTP-SP is suggestive of protecting the women from malaria infection, there was no significant difference observed between the two dosing schemes.
