Insights
Regular antimalarial drug administration, including prophylaxis or intermittent treatment, significantly reduces clinical malaria episodes and severe anemia in young children. This approach is a key strategy for malaria prevention in endemic regions.
Area of Science:
- Public Health
- Tropical Medicine
- Pediatrics
Background:
- Malaria frequently causes illness in children residing in malaria-endemic areas.
- Preventive strategies, such as regular antimalarial drug administration (prophylaxis or intermittent treatment), are being considered for preschool-aged children.
Purpose of the Study:
- To evaluate the effectiveness of antimalarial drugs administered at regular intervals (prophylaxis or intermittent treatment) in preventing malaria among young children in malaria-endemic regions.
Main Methods:
- A systematic review and meta-analysis of individually and cluster-randomized controlled trials were conducted.
- Searches included major databases (Cochrane, MEDLINE, EMBASE, LILACS) and contacted researchers.
- Data extraction and quality assessment were performed independently by two authors, with meta-analyses using random-effects models where appropriate.
Main Results:
- Twenty-one trials involving 19,394 children were included.
- Antimalarial prophylaxis or intermittent treatment significantly reduced clinical malaria episodes (RR 0.53, 95% CI 0.38 to 0.74) and severe anemia (RR 0.70, 95% CI 0.52 to 0.94).
- Fewer hospital admissions were observed (RR 0.64, 95% CI 0.49 to 0.82), with no significant difference in all-cause mortality (RR 0.90, 95% CI 0.65 to 1.23).
Conclusions:
- Regular administration of antimalarial drugs, through prophylaxis or intermittent treatment, is effective in reducing clinical malaria and severe anemia in preschool-aged children.
- This intervention is a valuable public health strategy for malaria control in endemic areas.
- Long-term effects on morbidity and mortality require further investigation with larger sample sizes.
Background:
Malaria causes repeated illness in children living in endemic areas. Policies of giving antimalarial drugs at regular intervals (prophylaxis or intermittent treatment) are being considered for preschool children.
Objectives:
To evaluate prophylaxis and intermittent treatment with antimalarial drugs to prevent malaria in young children living in malaria-endemic areas.
Search Strategy:
We searched the Cochrane Infectious Diseases Group Specialized Register (August 2007), CENTRAL (The Cochrane Library 2007, Issue 3), MEDLINE (1966 to August 2007), EMBASE (1974 to August 2007), LILACS (1982 to August 2007), mRCT (February 2007), and reference lists of identified trials. We also contacted researchers.
Selection Criteria:
Individually randomized and cluster-randomized controlled trials comparing antimalarial drugs given at regular intervals (prophylaxis or intermittent treatment) with placebo or no drug in children aged one month to six years or less living in a malaria-endemic area.
Data Collection And Analysis:
Two authors independently extracted data and assessed methodological quality. We used relative risk (RR) or weighted mean difference with 95% confidence intervals (CI) for meta-analyses. Where we detected heterogeneity and considered it appropriate to combine the trials, we used the random-effects model (REM).
Main Results:
Twenty-one trials (19,394 participants), including six cluster-randomized trials, met the inclusion criteria. Prophylaxis or intermittent treatment with antimalarial drugs resulted in fewer clinical malaria episodes (RR 0.53, 95% CI 0.38 to 0.74, REM; 7037 participants, 10 trials), less severe anaemia (RR 0.70, 95% CI 0.52 to 0.94, REM; 5445 participants, 9 trials), and fewer hospital admissions for any cause (RR 0.64, 95% CI 0.49 to 0.82; 3722 participants, 5 trials). We did not detect a difference in the number of deaths from any cause (RR 0.90, 95% CI 0.65 to 1.23; 7369 participants, 10 trials), but the CI do not exclude a potentially important difference. One trial reported three serious adverse events with no statistically significant difference between study groups (1070 participants). Eight trials measured morbidity and mortality six months to two years after stopping regular antimalarial drugs; overall, there was no statistically significant difference, but participant numbers were small.
Authors' Conclusions:
Prophylaxis and intermittent treatment with antimalarial drugs reduce clinical malaria and severe anaemia in preschool children.
