Reducing the Effects of Malaria in Children by Administering Repeated Preventive Doses
A Longitudinal Study Assessing the Infectious Status and Immunity of Mothers and Their Children in Lambaréné, Including Intermittent Treatment of Children With Sulfadoxine-pyrimethamine for Malaria Control and Its Impact on Long-term Health
Study Overview
Detailed Description
More than 1.5 million deaths of African children under 5 years of age are due to Plasmodium falciparum malaria. There is an urgent need for available and affordable strategies to control malaria morbidity in childhood.
Malaria control measures have been assessed for their potential to reduce intensity of infection in order to decrease the risk of malaria. It has been shown that malaria prevention using drugs is potentially capable to reduce malaria morbidity, school absenteeism, and all-cause mortality. However, prevention using drugs in the first years of life can also result in the loss or delay of acquired resistance which can lead to a rebound phenomenon (i.e. an increased risk of severe malaria after the therapy ended). In a recent study on intermittent treatment with Fansidar® at 2, 3, and 9 months of age, the number of malaria cases during the first 12 months of life was significantly reduced and no rebound effect was observed. This study has demonstrated that the intermittent administration of Fansidar® is safe and has beneficial effects for the children. However, the effectiveness decreased some months after discontinuing the drug. The promising effect of the intermittent administration of fansidar shown in this study needs to be confirmed in areas of different endemicity such as Lambaréné, Gabon. It is assumed that a more extended intermittent application of Fansidar® than performed in the above example would likely result in a longer period of protection from malaria, and the extended intermittent administration of Fansidar should not lead to rebound effects resulting in a higher occurrence of malaria.
The framework of this study offers a unique opportunity to study characteristics of infectious disease of importance in the Lambaréné area and the development of resistance against microbes at the maternofetal (mother/foetus) interface. Comparable studies will simultaneously take place in two associated study sites (Kumasi and Tamale) with different malaria endemicity in Ghana, West Africa.
Comparison: Comparison of malaria attacks in children with and without intermittent Fansidar® treatment with drug administration at months 3 and 9 (alongside with routine vaccinations delivered through child vaccination programme) and an additional administration at month 15.
