The impacts of hypoxia-inducible factor stabilizers on laboratory parameters and clinical outcomes in chronic kidney disease patients with renal anemia: a systematic review and meta-analysis

Abstract

Renal anemia in chronic kidney disease (CKD) is associated with poor outcomes. Hypoxia-inducible factor (HIF) stabilizer, which induces endogenous erythropoietin synthesis and enhances iron mobilization, is a novel treatment for anemia in CKD. We conducted a systematic review and meta-analysis to analyze the effect of HIF stabilizers in anemic CKD patients. This meta-analysis included 43 officially published articles and 3 unpublished studies (27 338 patients). HIF stabilizer treatment significantly increased hemoglobin (Hb) level when compared with placebo (mean difference 1.19 g/dL; 95% confidence interval 0.94 to 1.44 g/dL; P
