Abstract: Streptococcus pneumoniae is the most common typical bacterial cause of pneumonia among children. The World Health Organization (WHO) recommends a 5-day Amoxicillin-based empiric treatment. However, longer treatments are frequently used. This study aimed to compare shorter and longer Amoxicillin regimens for children with uncomplicated community acquired pneumonia (CAP). A search of PubMed, EMBASE, and Cochrane Central was conducted to identify randomized controlled trials (RCTs) comparing 5-day and 10-day courses of Amoxicillin for the treatment of CAP in children older than 6 months in an outpatient setting. Studies involving overlapping populations, lower-than-standard antibiotic doses, and hospitalized patients were excluded. The outcome of interest was clinical cure. Statistical analysis was performed using RevMan 5.4. Heterogeneity was assessed using the Cochran Q test and I2 statistics. Two independent authors conducted the critical appraisal of the included studies according to the RoB-2 tool for assessing the risk of bias in randomized trials, and disagreements were resolved by consensus. We used the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) tool to evaluate the certainty of evidence of our results. Three RCTs and 789 children aged from 6 months to 10 years were included, of whom 385 (48.8%) underwent a 5-day regimen. Amoxicillin-based therapy was used in 774 (98%) patients. No differences were found between 5-day and 10-day therapy regarding clinical cure (RR 1.01; 95% CI 0.98–1.05; p = 0.49; I2 = 0%). Subgroup analysis of children aged 6–71 months showed no difference in the rates of the same outcome (RR 1.01; 95% CI 0.98–1.05; p = 0.38; I2 = 0%). The GRADE tool suggested moderate certainty of evidence.
Conclusion: These findings suggest that a short course of Amoxicillin (5 days) is just as effective as a longer course (10 days) for uncomplicated CAP in children under 10 years old. Nevertheless, generalizations should be made with caution considering the socioeconomic settings of the studies included.
