Abstract

BACKGROUND: Various therapeutic iron preparations are available in the market, which differ in their pharmacokinetic and safety profiles. There is insufficient evidence regarding the superior safety or efficacy of one over the other. OBJECTIVES: To study the effects of iron preparations on various parameters like hemoglobin, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and serum ferritin. STUDY DESIGN: A systematic review and meta-analysis of randomized controlled trials (RCT) was conducted from inception till 3 June, 2022. DATA SOURCES AND SELECTION CRITERIA: Databases like MEDLINE and COCHRANE were searched for RCTs evaluating the effects and safety profile of various iron salts in the management of iron deficiency anemia in children and adolescents. MAIN RESULTS: Eight studies with a total of 495 children were included the review. Pooled analysis showed ferrous sulphate to cause a significant increase in hemoglobin compared with other iron compounds [mean difference (95% CI) 0.53 (0.22 to 0.83; P <0.001]. Also ferrous sulphate is superior to iron polymaltose complex (IPC) (P<0.001). However, there was a significant increase in gastrointestinal adverse effects with ferrous sulphate compared to IPC (P=0.03). Other iron compounds were more efficacious than IPC in raising hemoglobin levels (P<0.001). Among the few studies evaluating iron indices like MCV, MCH, and serum ferritin, there was no significant difference between the iron preparations (P>0.05). CONCLUSION: A low quality evidence suggests that ferrous sulphate is more efficacious than other compounds (P<0.001); though, there is an increase in gastrointestinal side effects with ferrous sulphate.
