Summary: | Scarcity of organs for transplantation makes living related donor transplantation lifesaving, but it may not be equitably distributed. In pediatric transplants, female adult living donors are more common, while male recipients are more common in low- and middle-income settings. Objective Paediatric living donor liver transplantation (LDLT) has gained popularity due to limited deceased donor organ supply. Some studies report inequalities in donor and recipient gender profiles, but data are sparse. We evaluated LDLT donor-recipient gender profiles, comparing country income categories and gender disparity level. Design We performed a systematic review, searching PubMed, Embase and Cochrane databases for publications dated January 2006-September 2021. We included full-text English articles reporting gender in >= 40 universally sampled donor-recipient pairs. Search terms were permutations of `liver transplant', `living donor' and `paediatric'. Countries were grouped as high/middle/low-income economies based on World Bank criteria and into groups based on deviation from gender parity in Gender Development Index (GDI) values (group 1 indicating closest to gender parity, group 5 indicating furthest). Proportions analysis with corresponding 95% CI were used for analysis of dichotomous variables, with significance when 95% CI did not cross 0.5. Data are reported as female proportion (%) and 95% CI. Results Of 12 525 studies identified, 14 retrospective studies (12 countries; 6152 recipients and 6138 donors) fulfilled study inclusion criteria. Male recipient preponderance was seen in lower middle-income countries (all were also GDI group 5) (39.3 (95% CI 34.7 to 44.0)) and female recipient preponderance in GDI groups 1 and 3. Female donor preponderance was seen overall (57.4% (95% CI 55.1 to 59.6)), in middle income countries and in three of four GDI groups represented. Conclusion There are significant imbalances in recipient-donor gender profiles in paediatric LDLT that are not well explained. The reasons for overall female donor preponderance across income tiers must be scrutinised. |
