Objective To review the influence of 131I therapy on bone mineral density (BMD) in patients with hyperthyroidism.Methods Published articles of prospective randomized controlled study,clinical controlled study or case-control study on BMD change in patients with hyperthyroidism after 131I therapy were selected from PubMed,the Excerpta Media Database (Embase),Cochrane library,Chinese Journal Full-text Database,Wanfang Database,Vip Database and Chinese Biomedical Literature Database.Data from the date of database establishment to October 2015 were all reviewed.The languages were restricted to English and Chinese.Meta-analysis was performed with RevMan 5.3.Results Thirteen trials with a total of 668 hyperthyroidism patients were included.The meta-analysis showed that BMD of the lumbar spine,hip joint,femoral neck and osteocalcin were significantly improved after 131I therapy.The weighted mean difference (WMD) for BMD of the lumbar spine was 0.07 (95% CI:0.04-0.11),P=0.O00 2;that of the hip joint and the femoral neck was 0.13(95% CI:0.09-0.16) and 0.05(95% CI:0.03-0.06),respectively(both P<0.01).The standardized mean difference (SMD) of osteocalcin was-1.20(95% CI:-1.43--0.97) with P<0.01.Furthermore,the improvements were time dependent within the 2 years' follow-up.Conclusions 131I therapy improves the BMD and osteocalcin in patients with hyperthyroidism in a time dependent manner within 2 years' follow-up.
