African trypanosomiasis medical therapy
Introduction
Overview
Overview
Medical treatment of African trypanosomiasis should begin as soon as possible and is based on the infected personβs symptoms and laboratory results. Pentamidine isethionate and suramin (under an investigational New Drug Protocol from the CDC Drug Service) are the drugs of choice to treat the hemolymphatic stages of West and East African Trypanosomiasis, respectively. Melarsoprol is the drug of choice for late disease with central nervous system involvement (infections by T.b. gambiense or T. b. rhodiense). Hospitalization for treatment is necessary. Periodic follow-up exams including a spinal tap are required for 2 years. If a person fails to receive medical treatment for African trypanosomiasis, death will occur within several weeks to months.[1][2][3][4]

- 1.2.2 Pediatric
- Preferred regimen: Melarsoprol 2-3.6 mg/kg/day IV for 3 days. After 7 days, 3.6 mg/kg/day for 3 days. Give a 3rd series of 3.6 mg/kg/d after 7 days
- 2. West African trypanosomiasis
- 2.1 T. b. gambiense, hemolymphatic stage
- 2.1.1 Adult
- Preferred regimen: Pentamidine 4 mg/kg/day IM/IV for 7-10 days
- 2.1.2 Pediatric
- Preferred regimen: Pentamidine 4 mg/kg/day IM/IV for 7-10 days
- Note (1): Pentamidine should only be used during pregnancy and lactation if the potential benefit justifies the potential risk
- Note (2): IM/IV Pentamidine have a similar safety profile in children age 4 months and older as in adults. Pentamidine is listed as a medicine for the treatment of 1st stage African trypanosomiasis infection (Trypanosoma brucei gambiense) on the WHO Model List of Essential Medicines for Children, intended for use in children up to 12 years of age
- 2.2 T. b. gambiense, CNS involvement
- 2.2.1 Adult
- Preferred regimen: Eflornithine 400 mg/kg/day IV qid for 14 days
- 2.2.2 Pediatric
- Preferred regimen: Eflornithine 400 mg/kg/day IV qid for 14 days
- Note (1): Eflornithine should only be used during pregnancy and lactation if the potential benefit outweighs the potential risk
- Note (2): The safety of eflornithine in children has not been established. Eflornithine is not approved by the Food and Drug Administration (FDA) for use in pediatric patients. Eflornithine is listed for the treatment of 1st stage African trypanosomiasis in Trypanosoma brucei gambiense infection on the WHO model List of Essential Medicines for Children, intended for use in children up to 12 years of age
