Vanishing Bile Duct Syndrome in Pediatric Hodgkin Lymphoma: First Statistical Analysis of All Published Cases in...

Hodgkin lymphoma with vanishing bile duct syndrome is a rare paraneoplastic syndrome and has never been studied in the pediatric population. The objectives of this study were to determine the clinical characteristics of this rare condition in children through a literature review, and a descriptive analysis of all published cases with the index case report. All reported cases fulfilling the inclusion criteria were found through a literature search, and analyzed in descriptive statistics. A total of 10 cases were included in the study with a median age of 9.5 years and a male-to-female ratio of 9:1. The median duration of symptoms was 5.5 weeks with 3 cases having jaundice before the symptoms of lymphoma. The median bilirubin level was 8.4 mg/dL. Seven cases received modified chemotherapy, and 5 used ursodeoxycholic acid. The survival rate was 50%. Normalization of liver functions after the lymphoma treatment was observed in 4 cases and was the only statistically significant factor ( P =0.01) associated with the outcome. This is a rare entity in the pediatric population with a guarded prognosis comparable to the adult counterparts but a marked male predominance.
