Long-Term Outcome of Kidney Transplant Among Iranian Children: A Systematic Review and Meta-Analysis.

Objectives: End-stage kidney disease has dramatic health effects and life consequences in children. Presently, kidney transplant has been globally accepted as a treatment of choice for end-stage kidney disease in both children and adults, leading to better quality of life and longer patient survival. Because of lack of comprehensive information on the outcome of kidney transplant among children in Iran, we aimed to present a proper vision of pediatric kidney transplant in Iran by systematically reviewing the current literature.

Materials And Methods: Major databases were searched, including Medline, Web of Knowledge, Google Scholar, Scopus, Cochrane, and the Iranian Scientific Information Database for all eligible studies in accordance with specific keywords. The inclusion criteria forthe retrieved studies were determination of graft survival, patient survival, and reasons for graft failure. The exclusion criteria were as follows: (1) a lack of clearresults; (2) non-English or non-Persian language format; (3) lack of access to the full-text manuscripts; and (4) case reports, case series, and review papers. A total of 115 studies were initially assessed based on the keywords; of these, 8 met inclusion criteria and were considered for final analysis; these were published between 2005 and 2017.

Results: According to our results, 1-year graft survival rates were overall 89.7%, and 5-year graft survival rates were 65.4%. The 1-year patient survival rates were estimated to be 97.1%, and 5-year patient survival rates were estimated to be 89.8%. Acute rejection, dialysis status before transplant, and inappropriate immunosuppression were the main risk factors.

Conclusions: Our systematic review and meta-analysis indicated a high success rate of childhood kidney transplant in Iran according to long-term graft and patient survival rates.
