Neuromuscular complication after liver transplant in children: a single-center experience

Area of Science:

• Pediatric Hepatology
• Pediatric Neurology
• Transplant Medicine

Background:

• Neurologic complications are a significant source of morbidity in children undergoing liver transplantation.
• Understanding these complications is crucial for improving post-transplant outcomes in pediatric patients.

Purpose of the Study:

• To prospectively evaluate the incidence and types of neurologic complications in children after liver transplant.
• To identify potential associations between immunosuppressive regimens and observed neurologic side effects.

Main Methods:

• A prospective study included children under 18 who received a liver transplant between June 2004 and June 2007.
• Data collected included patient demographics, transplant indications, immunosuppressive medications, and documented neurologic complications.
• Follow-up duration averaged 21.6 months.

Main Results:

• The most common indications for liver transplant were biliary atresia, Wilson disease, and tyrosinemia.
• Tacrolimus was the primary immunosuppressant (91.7%), often combined with mycophenolate mofetil.
• The most frequent neurologic complications observed were tremor (16.7%), convulsions (12.5%), and insomnia (12.5%).

Conclusions:

• Tremor is the predominant neurologic complication in children post-liver transplant, consistent with findings in adult populations.
• The high prevalence of tremor may be associated with the widespread use of tacrolimus in this pediatric cohort.
• Further research is warranted to explore the specific mechanisms linking tacrolimus and tremor in pediatric liver transplant recipients.
