Mortality outcomes and clinical background of children on maintenance dialysis without receiving kidney transplantation.

BACKGROUND

Some pediatric patients on maintenance dialysis may need end-of-life care in the future because of being excluded from the indication of kidney transplantation and experiencing difficulty in continuation of their dialysis. This study aimed to thoroughly elucidate mortality outcomes of children on maintenance dialysis including the cause of death and clinical background of exclusion from indication of transplantation.

PATIENTS AND METHODS

This single-center retrospective study enrolled 53 children who received kidney transplantation (5) or maintenance peritoneal dialysis (PD, 48) as initial renal replacement therapy (RRT). We examined the selected RRT modalities, mortality outcomes, clinical backgrounds of cause of death, and risk factors of excluding from future the indication of transplantation.

RESULTS

Nine (17%) of all 53 patients, all receiving PD (9/48, 19%), were finally excluded from next RRT indication-7 were excluded due to severe extrarenal complications that indicated high risk for transplantation and 2 were excluded due to severe psychomotor retardation and at the guardians' discretion. Patients who were excluded from the indication had a younger age at PD induction and higher proportion of cerebral and cardiac complications or psychomotor retardation than patients who were included in the indication. Of the nine patients, seven died; of which, one patient died due to fatal progression of extrarenal complications and six died due to infectious or noninfectious dialysis-related complications.

CONCLUSION

Patients with severe extrarenal complications or psychomotor retardation tend to be excluded from the indication of transplantation. Their condition becomes fatal because of the complications of long-term dialysis and progression in extrarenal complications.
