Evaluation of Underlying Liver Disease and Its Severity in Children Referred for Liver Transplant: a Single-Center Report From Nemazee Hospital of Shiraz.

OBJECTIVES

Liver transplant has been used as a curative approach for children with end-stage liver diseases. Here, we describe the underlying causes for pediatric liver transplant performed at the Shiraz Organ Transplantation Center, Nemazee Hospital, Shiraz, Iran.

MATERIALS AND

METHODS

In this cross-sectional descriptive study, children < 18 years old who were candidates for liver transplant from 2007 to 2010 at the Shiraz Organ Transplantation Center were included. Patients were evaluated for their underlying diseases leading to liver failure. Disease severity was assessed and compared with Pediatric End-Stage Liver Disease model and the Model for End-Stage Liver Disease scores.

RESULTS

Of 107 patients, 60.8% were males and 39.2% were females. The mean age was 11.6 ± 4.9 years. Thirteen patients (12.5%) were < 2 years old, 26 (24%) were 2 to 6 years old, 33 (30.8%) were 6 to 12 years old, and 35 (32.7%) were 12 to 18 years old. Underlying liver diseases comprised biliary atresia (27.1%), cryptogenic cirrhosis (21.5%), autoimmune cirrhosis (13.1%), familial intrahepatic cholestasis (11.2%), Wilson disease (9.3%), tyrosinemia (7.4%), neonatal hepatitis (4.7%), congenital hepatic fibrosis (3.7%), and Caroli disease (1.9%). Jaundice (83.2%), ascites (57%), and esophageal varices (43%) were the most common clinical findings. Mean serum direct bilirubin, total bilirubin, international normalized ratio, and serum creatinine values were 3.6 ± 0.8 mg/dL, 9.3 ± 9.1 mg/dL, 2.1 ± 1.1, and 0.6 ± 0.2 mg/dL, respectively. The mean Pediatric End-Stage Liver Disease score in children < 12 years old was 11.4 ± 9.1. The mean Model for EndStage Liver Disease score in children > 12 years old was 13.7 ± 5.9. There were no differences in scores among sex, age groups, or different etiologies.

CONCLUSIONS

Scores for disease severity were not significantly different with regard to different causes of underlying diseases for liver transplant in Iranian children.
