Abstract

Abstract : Information related to short‐ and long‐term risks of children born to kidney‐transplanted women remains limited. With the aim of investigating the risk of neonatal complications, and the short‐ and long‐term risk of infections in offspring of kidney‐transplanted women, all children born to kidney‐transplanted women in Denmark from 1964 to 2016 were identified in a nationwide retrospective matched cohort study. A total of 124 children of kidney‐transplanted women were identified and matched on gender, birth year, and number of siblings at birth 1:10 with children born to nontransplanted women identified in the Danish general population. Prevalence of low birth weight (37.9%, risk ratio [RR] = 12.61; 95% confidence interval [CI], 8.5‐18.5), premature birth (46.0%, RR = 11.32; 95% CI, 8.1‐15.7) and malformations (11.3%, RR = 1.98; 95% CI, 1.2‐3.4) was increased in children of kidney‐transplanted women compared with controls. Similarly, prevalence of hospitalization due to infection was increased during the first year of life (21.0%, RR = 1.94; 95% CI, 1.3‐2.8), from age 1 to 5 (34.2%, RR = 1.89; 95% CI, 1.4‐2.5), and overall (41.9%, RR = 1.67; 95% CI, 1.3‐2.1). The risk of infection was also higher in children of kidney‐transplanted mothers born preterm or with low birth weight compared with similar controls. In conclusion, risk of neonatal complications, malformations, and both early and late infection were increased in children born to kidney‐transplanted women. Abstract : A nationwide retrospective matched cohort study shows that the risk of neonatal complications, malformations, and infection, both early and late, was increased for children born to kidney‐transplanted women compared to nontransplanted women.
