Transition of adolescent and young adult patients with childhood-onset chronic kidney disease from pediatric to adult renal services: a nationwide survey in Japan.

BACKGROUND

Transition of adolescent and young adult (AYA) patients with childhood-onset chronic kidney diseases (C-CKD) from pediatric to adult renal services has received increasing attention. However, information on transition of Japanese patients with C-CKD is limited.

METHODS

The Transition Medicine Working Group, in collaboration with the Japanese Society for Nephrology, the Japanese Society for Pediatric Nephrology and the Japanese Society of Pediatric Urology, conducted a retrospective cross-sectional study in 2014 on issues concerning the transition of Japanese patients with C-CKD.

RESULTS

Few institutions in Japan had transition programs and/or transition coordinators for patients with C-CKD. Refusal to transfer by patients or their families, lack of concern about transition and inability to decide on transfer were common reasons for non-transfer of patients still followed by pediatric renal services. Around 25 % of patients who had ended or interrupted follow-up by pediatric renal services presented to adult renal services because of symptoms associated with C-CKD. Patients with various types of childhood-onset nephrourological diseases were transferred from pediatric to adult renal services. IgA nephropathy, minimal change nephrotic syndrome and congenital anomalies of the kidney and urinary tract were the most frequent primary kidney diseases in adult patients with C-CKD.

CONCLUSION

These survey results indicate the need for introduction of transitional care for Japanese AYA patients with C-CKD. Consensus guidelines for the optimal clinical management of AYA patients with C-CKD are required to ensure the continuity of care from child to adult renal services.
