Insights
Vitamin A supplementation for children with pneumonia improves clinical response and shortens recovery time without increasing adverse effects. This review highlights vitamin A
Area of Science:
- Pediatric Pulmonology
- Nutritional Science
- Evidence-Based Medicine
Background:
- Pneumonia is a leading cause of childhood mortality globally.
- Vitamin A deficiency is common in children with pneumonia.
- The role of vitamin A as an adjuvant therapy for pneumonia requires clarification.
Purpose of the Study:
- To systematically review and meta-analyze randomized controlled trials (RCTs) investigating the efficacy and safety of vitamin A supplementation in children with pneumonia.
Main Methods:
- Comprehensive literature search across multiple databases (Cochrane Library, EMbase, PubMed, etc.).
- Inclusion of 15 RCTs involving 3,021 pediatric patients.
- Meta-analysis performed using RevMan5.3 software.
Main Results:
- Vitamin A supplementation did not significantly reduce pneumonia-related mortality.
- It significantly increased the overall clinical response rate.
- It shortened the duration of fever, cough, abnormal chest X-ray findings, and hospital stay.
Conclusions:
- Vitamin A as an adjuvant therapy effectively alleviates clinical symptoms and signs in pediatric pneumonia.
- It contributes to a reduced length of hospital stay.
- No increased incidence of adverse reactions was observed with vitamin A supplementation.
Objective:
To investigate the effect and safety of vitamin A supplementation in children with pneumonia through a systematic review.
Methods:
Cochrane Library, EMbase, PubMed, China Biology Medicine disc, CNKI, and Wanfang Data were searched for randomized controlled trials (RCTs) on vitamin A as an adjuvant therapy for pneumonia in children. Two reviewers independently screened the studies and evaluated their quality according to the inclusion and exclusion criteria. RevMan5.3 was used for the Meta analysis.
Results:
A total of 15 RCTs with 3 021 patients were included. The Meta analysis showed that vitamin A supplementation did not reduce the mortality of children with pneumonia (P>0.05), but it increased the overall clinical response rate (P<0.05) and shortened the duration of pyrexia and cough, clearance time of signs and abnormal chest X-ray results, and length of hospital stay (P<0.05). As an adjuvant therapy, vitamin A did not increase the incidence rates of adverse reactions such as nausea, vomiting, diarrhea, allergy, and bregma bulging.
Conclusions:
Current evidence shows that in the treatment of pneumonia in children, vitamin A supplementation helps to relieve clinical symptoms and signs and shorten the length of hospital stay.The adjuvant therapy does not increase the incidence rates of adverse reactions.
