Safety of renal transplantation in patients with bipolar or psychotic disorders: a retrospective study

Solid organ transplantation societies recommend a relative contraindication of transplantation for people with bipolar or psychotic disorders. Very few data are available on the outcome of kidney transplantation and the increased risk of kidney disease in those patients. We conducted a retrospective multicenter cohort study (1979-2014) including kidney allograft recipients with either bipolar (BD) or psychotic disorders prior to transplant. Objectives were kidney allograft and patient outcomes compared to a matched control group without psychiatric disorders and the evolution of psychiatric disorder at 60months after transplantation. Forty-seven patients including 25 women were identified, 34 with BD and 13 with psychotic disorder. Patients' overall cumulative death rates at 60months were not significantly different in both groups [12.2%; 95% confidence interval: (4.5-24.1) in the group with psychiatric disorder versus 5.2%; (1.7-11.7) in control group P=0.11] as for cumulative allograft loss rates [11.7% (3.5-25.2) vs. 9.4% (4.4-16.8) in control group (P=0.91)]. Twenty-three patients (16 with BD and seven with psychotic disorder) experienced at least one psychiatric relapse [incidence rate: 1.8/100 persons- months; 95% CI; (1.2-2.7)] totaling 13 hospitalizations within 60months of follow-up. Four patients stopped immunosuppressive therapy leading to allograft loss in three. Our study suggests that patients with BD or psychotic disorders have to be considered for renal transplantation with close psychiatric follow-up after transplant.
