Brief Summary

Following the development of drug resistance to antimalarial first line treatment of uncomplicated malaria with SP by P.falciparum in mainland Tanzania, the Ministry of Health - Tanzania, introduced ACTs with AL as first line treatment for uncomplicated falciparum malaria in 2006. In the advent of wide scale deployment of ACT together with strengthened vector control with LLIN in mainland Tanzania, there is a trend of shrinking the burden of malaria. The decline of outpatient malaria cases in recent years and declining entomological inoculation rates (EIR) that are currently being recorded in most areas that were before considered to be holo/hyper-endemic to malaria transmission is another indicator of the shift in the epidemiology of malaria transmission in Tanzania. This current shift provides a new and yet critical challenge with regards to assessment and monitoring of the efficacy of the first-line treatment specifically considering that artemisinin resistance has been confirmed in the Greater Mekong sub-region. The aim of the study was to set up a system for country wide representative surveillance to obtain data of the safety and efficacy of AL following countrywide use of ACTs for treatment of uncomplicated malaria in Tanzania. The study was conducted in the framework of the existing NMCP sentinel sites that are ecological representative for malaria endemicity in Tanzania Objective: To assess the efficacy and safety of artemether-lumefantrine, artesunate-amodiaquine and dihydroartemisinin-piperaquine for the treatment of uncomplicated falciparum malaria in Tanzania. Methods: The study was conducted in eight sentinel sites of NMCP (Kyela, Mkuzi, Kibaha, Ujiji, Nagaga, Chamwino, Igombe and Mlimba) in mainland Tanzania. Four sentinel sites (Mlimba, Mkuzi, Kibaha, and Ujiji) were covered in 2016 and the rest will be involved in the second round to be undertaken in 2017. Patients were treated with AL for 3 days and the study was conducted from April to Sept 2016. The results of this study will assist the Ministry of Health to monitor the efficacy and safety of the ACTs in Tanzania, provide baseline data on parasite clearance time and for assessing the current national treatment guidelines for uncomplicated falciparum malaria.
