Aetiology, Prevention and Control of Anaemia in Sub-Saharan Africa - Work Package 2: Efficacy Study: Efficacy of 2 Iron Fortified Porridges and IPT for the Prevention of Anemia in Young Children in Côte d'Ivoire.

The proposed project is aimed at testing two interventions, namely a highly bioavailable iron compound and a combination of SP plus amodiaquine for intermittent preventive treatment (IPT) of malaria, to reduce anaemia in very young children.

Descripción detallada

Efficacy study - ANAEMIA project Côte d'Ivoire The proposed project is aimed at testing two interventions, namely a highly bioavailable iron compound and a combination of SP plus amodiaquine for intermittent preventive treatment (IPT) of malaria, to reduce anaemia in very young children. The fortified product will be provided as porridge (Nutribon produced by PKL) with an optimized formula (2 mg in the form of NaFeEDTA and 3.8 mg in the form of ferrous fumarate) of the premix. In addition, we will assess the Nutribon product currently available on the market and we will compare it to an optimized premix formula. The current and the optimized formula contain each 2 mg iron in the form of NaFeEDTA. In addition to the NaFeEDTA the current premix contains 3.8 mg in the form of ferric pyrophosphate, which is less bioavailable than the 3.8 mg ferrous fumarate in the optimized formula. The study will be carried out between May and December 2012 which includes the rainy season (April - October) with its two peaks in Côte d'Ivoire and thus the period when malaria transmission is highest. The study will be implemented in a Health and Demographic Surveillance System in Taabo in Côte d'Ivoire and comprise 625 children between 12 to 36 months. 375 eligible infants will receive a fortified porridge (250 with the improved formula and 125 with the current formula), whereas 250 infants will continue with their local diet (control group). Infants receiving the optimized formula and infants in the control group will be randomly assigned to IPT of malaria (125 in each group) or placebo (125 in each group). Thus, infants can be assigned to one of the following five groups: 1. group (n=125): fortified porridge (optimized formula) and IPT of malaria 2. group (n=125): fortified porridge (optimized formula) and placebo 3. group (n=125): local diet and IPT of malaria and 4. group (n=125): local diet and placebo. 5. group (n=125): fortified porridge (current formula) and placebo, representing the current situation in Côte d'Ivoire in infants consuming fortified complementary food. This efficacy trial will deepen our understanding in preventing anaemia and the interaction of bioavailable iron compounds with an antimalarial drug and related conditions in very young children. Further, the study should demonstrate whether the earlier study failed to show an impact on anaemia due to the use of an iron compound that lacked bioavailability and/or using an antimalarial drug in the IPT intervention arm that lacked efficacy perhaps due to resistance by P. falciparum, or other yet to be investigated causes.

Periodo de tiempo
Hemoglobin
Periodo de tiempo: 9 months
The study population will consist of 12 to 36-month-old infants in villages covered by the Taabo DSS site. Assuming a mean Hb of 97.3±19.6 g/l and that an increase of 8 g/l in Hb would be clinically relevant, and allowing for a dropout rate of 20%, we calculated that 125 infants per group were initially needed to achieve a power level of 90% at a 5% level of significance.
