Kidney transplantation in uremic children with cystinosis

Area of Science:

• Pediatric Nephrology
• Transplantation Immunology
• Genetics and Rare Diseases

Background:

• Infantile cystinosis is a rare genetic disorder leading to progressive kidney damage and end-stage renal disease (ESRD).
• Uremia in children with infantile cystinosis presents significant challenges for long-term management and survival.
• Renal transplantation is a potential therapeutic option for these patients, but outcomes data are limited.

Purpose of the Study:

• To evaluate the efficacy and long-term outcomes of cadaveric renal transplantation in children with infantile cystinosis.
• To assess the impact of transplantation on systemic complications of cystinosis.
• To determine if renal transplantation is the preferred treatment for uremic children with this condition.

Main Methods:

• Retrospective analysis of 10 children aged 8.0-12.5 years who underwent cadaveric renal transplantation.
• Monitoring of graft survival, patient survival, and recurrence of systemic complications post-transplantation.
• Assessment of complications including acute rejection and viral encephalitis.

Main Results:

• Six out of ten children are alive with functioning grafts 6-62 months post-transplantation.
• Three patients died from uremia or viral encephalitis after requiring a second graft.
• One patient lost her graft due to acute rejection and is now on hemodialysis.
• No further systemic cystinosis complications were observed in patients with functioning grafts.

Conclusions:

• Cadaveric renal transplantation is a viable and effective treatment for uremic children with infantile cystinosis.
• Successful transplantation can halt the progression of systemic complications associated with the disease.
• Careful monitoring for rejection and opportunistic infections is crucial for long-term graft and patient survival.
