Objectives: Patients with liver transplant can present to a pediatric emergency department with short- and long-term complications of transplant. Here, we described clinical features of pediatric liver transplant patients admitted to the pediatric emergency department and identified risk factors that may lead to pediatric intensive care unit admission.
Materials and methods: We retrospectively evaluated pediatric liver transplant patients admitted posttransplant to Baskent University Hospital's pediatric emergency department in 2023. We noted symptoms, laboratory tests, hospitalization status, and final diagnoses. We compared clinical and laboratory features of patients admitted or not admitted to the intensive care unit.
Results: In 2023, 108 presentations of 33 liver transplant patients presented to our pediatric emergency department: 46.3% were girls, mean age was 7.79 ± 4.40 years, and median posttransplant day at time of emergency department visit was 622 days. Common symptoms were vomiting (48%), fever (46%), and rhinorrhea and cough (34%). Forty-nine visits (45.4%) resulted in hospitalization; 5 visits (4.6%) resulted in PICU admission, with 2 mortalities (1.8%). Final diagnoses included acute gastroenteritis and upper respiratory tract infections (23 patients) and lower respiratory tract infections (13 patients). Seven patients had cholangitis, 6 had intra-abdominal infection, and 5 had sepsis. Seizures and sepsis were significantly correlated with intensive care unit admission (P <.001). Patients admitted to the intensive care unit had significantly shorter time posttransplant versus other patients (518 ± 324 vs 1498 ± 1658 days; P < .001).
Conclusions: Half of patients who presented to the emergency department required hospitalization mainly for observation and supportive treatment, with a small number requiring intensive care unit admission. Nevertheless, physicians caring for liver transplant patients should be aware of serious complications and monitor patients closely, especially early posttransplant when intensive immunosuppressive treatment regimens are used.
