Insights
Mefloquine effectively treats imported childhood malaria. While vomiting is common in younger children, a second dose can ensure successful treatment outcomes for Plasmodium falciparum.
Area of Science:
- Pediatric Infectious Diseases
- Tropical Medicine
- Pharmacology
Background:
- Uncomplicated Plasmodium falciparum malaria in children is treated with various antimalarials, including mefloquine.
- Limited data exist on mefloquine's efficacy for imported malaria in pediatric populations.
Purpose of the Study:
- To evaluate the treatment efficacy of oral mefloquine for uncomplicated imported Plasmodium falciparum malaria in children.
- To identify factors associated with early vomiting after mefloquine administration.
Main Methods:
- Prospective study of 95 children (3 months–16 years) treated with oral mefloquine and an antiemetic.
- Clinical data, including travel history, symptoms, and laboratory parameters, were collected.
- Follow-up for 45 days to assess treatment efficacy and relapse.
Main Results:
- Mefloquine achieved initial cure in all children, with no P. falciparum relapses within 45 days.
- Vomiting occurred within 1 hour of dosing in 20% of children, significantly associated with lower weight (≤ 15 kg).
- Most children (94%) had traveled to the Indian Ocean region; compliance with chemoprophylaxis was low.
Conclusions:
- Mefloquine is an effective treatment for uncomplicated imported P. falciparum malaria in children from regions with low mefloquine resistance.
- Early vomiting is a frequent side effect, particularly in children under 15 kg, but can be managed with a second dose.
- This highlights the importance of weight-based dosing and antiemetic co-administration.
Background:
Children with uncomplicated Plasmodium falciparum imported malaria are treated with various antimalarial regimens including mefloquine depending on national guidelines. Little is known regarding mefloquine treatment efficacy in this setting.
Methods:
In this prospective study, children 3 months to 16 years of age admitted in a tertiary hospital emergency ward in France with uncomplicated P. falciparum malaria were treated with oral mefloquine. Each dose was given with an antiemetic.
Results:
Between 2004 and 2009, 95 children were evaluated. In all, 94% had traveled in the Indian Ocean region (Comoros and Madagascar); 79% used a malaria chemoprophylaxis, but none was fully compliant with World Health Organization recommended regimens. Main clinical features at admission were fever (91%), vomiting (44%), and headaches (44%). Hemoglobin < 80 g/L and platelets <100 G/L were observed in 16% and 17%, respectively. All children were initially cured by mefloquine, and no relapse was noted within 45 days after admission. One Plasmodium vivax relapse occurred 6 months later. Vomiting within 1 hour after dosing occurred in 20% of children. Significant features associated with early vomiting by univariate analysis were a weight ≤ 15 kg, C-reactive protein ≥ 50 mg/L, and parasitemia ≥ 1%, but only low weight was significant by multivariate analysis.
Conclusion:
Mefloquine is an effective treatment for uncomplicated imported P. falciparum malaria in children returning from countries with low mefloquine resistance. Early vomiting after mefloquine dosing is frequent, especially in children < 15 kg of weight, but a second dose can be given successfully.
