Summary
Infectious diseases are among the most common causes of mortality in the over 2.5 million children under 5 years of age (U5) who died in 2018 in sub-Saharan Africa (SSA). New approaches to treatment and prevention of these diseases are needed to increase child survival. Sierra Leone has one of the highest rates of under-five child mortality in the world. It is estimated that 32,000 children die each year, the leading causes being neonatal conditions, malaria, pneumonia and diarrhea. In Sierra Leone, the available information on malaria indicates that it accounts for 38% of deaths among under-five children. Reducing the prevalence and impact of the disease among the general population is a major priority of the Ministry of Health and Sanitation (MoHS) of Sierra Leone .
Intermittent Preventative Treatment in infants (IPTi) - the administration of a full course antimalarial treatment to infants at individual timepoints regardless of infection statushas been shown to reduce clinical malaria and anemia in infants in the first year of life . When delivered alongside the Expanded Program on Immunization (EPI), IPTi with Sulphadoxine-pyrimethamine (SP) is a highly cost-effective intervention. . Sierra Leone is currently the only country that implements nationwide the World Health Organization's (WHO) IPTi guideline, which is administered within the first year of life. However, its benefit when expanded into the second year of life remains unknown. Taking the advantage of the inclusion in the EPI program of a booster dose of measles vaccine at 15 months of age, the ICARIA trial will also assess the efficacy of adding a dose of IPTi-SP at this age.
Recent studies show that azithromycin (AZi) - a macrolide antibiotic with some antimalarial effect- is associated with a significant reduction in childhood mortality when used in mass drug administration (MDA) for trachoma elimination in areas of sub-Saharan Africa (SSA) with child mortality rates far beyond Sustainable Development Goals , . However, despite the potential benefit of the intervention several fundamental scientific questions need to be answered before it can be recommended for large-scale implementation.
Description
In order to generate the conclusive evidence needed to inform policy and accelerate the implementation of this intervention, we propose to carry out a large-scale clinical trial on the impact on all-cause mortality up to 18 months of age of AZi administration through EPI. The potential development of antibiotic and SP resistance, AZi and SP interactions with routine immunizations, as well as the safety and the impact on the health system will be all assessed in the ICARIA trial.
To provide the evidence needed to inform policy and practice and to accelerate the implementation of this intervention, a large-scale clinical trial on the impact on all-cause mortality up to 18 months of age of AZi administration through the World Health Organisation Expanded Program on Immunisation (EPI) will be carried out in Sierra Leone. The clinical trial will be individually randomised, placebo-controlled with a factorial design whereby AZi will be administered alongside routine preventive health interventions of the EPI, such as immunisations and Intermittent Preventive Treatment in infants (IPTi), which is recommended by the WHO for malaria prevention in this age group. The potential development of antibiotic resistance, the interactions with routine immunisations, the safety and the impact on the health system of AZi administration will be all assessed in this trial.
