Folate supplementation in people with sickle cell disease.

CONCLUSIONS: One doubIe-blind, placebo-controlled triaI on folic acid supplementation in children with SCD was included in the review. Overall, the trial presented mixed evidence on the review's outcomes. No trials in adults were identified. With the limited evidence provided, we conclude that, while it is possible that folic acid supplementation may increase serum folate levels, the effect of supplementation on anaemia and any symptoms of anaemia remains unclear.If further trials were conducted, these may add evidence regarding the efficacy of folate supplementation. Future trials should assess clinical outcomes such as folate concentration, haemoglobin concentration, adverse effects and benefits of the intervention, especially with regards to SCD-related morbidity. Such trials should include people with SCD of all ages and both sexes, in any setting. To investigate the effects of folate supplementation, trials should recruit more participants and be of longer duration, with long-term follow-up, than the trial currently included in this review. However, we do not envisage further trials of this intervention will be conducted, and hence the review will no longer be regularly updated. PMID: 29546732 [PubMed - as supplied by publisher]
