Clinically "silent" weight loss associated with mycophenolate mofetil in pediatric renal transplant recipients
1Department of Pediatrics, Cincinnati Children's Hospital Medical Center, Cincinnati, OH 45229, USA.
Abstract:
Mycophenolate mofetil (MMF) has become a standard component of immunosuppressive regimens in adult and pediatric renal transplantation. Especially in children, MMF is known to have clinically obvious gastrointestinal side effects such as diarrhea or abdominal pain that can be dose-limiting or require drug discontinuation. In contrast, we report isolated weight loss unaccompanied by obvious clinical gastrointestinal symptoms in two pediatric renal transplant patients taking MMF. Both patients began gaining weight again after conversion to azathioprine. Accordingly, subspecialists and generalists caring for pediatric kidney transplant recipients taking MMF should be aware of this clinically "silent" complication.
Insights
Mycophenolate mofetil (MMF) can cause silent weight loss in pediatric kidney transplant patients. Awareness is crucial as this side effect may require medication adjustment.
Area of Science:
- Nephrology
- Pediatric Transplantation
- Pharmacology
Background:
- Mycophenolate mofetil (MMF) is a standard immunosuppressant in renal transplantation.
- Pediatric patients often experience gastrointestinal side effects with MMF.
Observation:
- Two pediatric renal transplant patients on MMF presented with unexplained weight loss.
- These patients had no obvious gastrointestinal symptoms.
Findings:
- Isolated weight loss occurred in pediatric renal transplant recipients receiving MMF.
- Weight gain was observed after switching to azathioprine.
Implications:
- Clinicians should consider "silent" weight loss as a potential MMF complication in children.
- Early recognition and management of MMF-associated weight loss are important for pediatric transplant outcomes.
