Fifteen years single center experience in the management of progressive familial intrahepatic cholestasis of infancy

Recent advances in genetics and in physiopathology of bile com- position and excretion have clarified the understanding of pro- gressive familial intrahepatic cholestasis (PFIC). The aim of the present study is to review the experience of our center in terms of diagnosis, management and outcome of 49 pedi- atric PFIC patients, belonging to the three classical subtypes described. We analyse the clinical, biological, and histological patterns and review the response to the medical and surgical treatment and the global outcome. The only clinical difference between the different subtypes of PFIC patients was the intensity of pruritus. Serum gamma-glu- tamyltransferase (GGT) and liver histology allowed to differenti- ate PFIC III from PFIC I and II patients. High levels of biliary bile acids in 2 low-GGT patients was asso- ciated with favourable outcome. Response to ursodesoxycholic acid (UDCA) varies from patient to patient and was not associat- ed to a particular subtype of PFIC. In five patients of this cohort, external biliary diversion was performed without improvement. Transplantation is indicated whenever medical treatment fails to restore normal social life, growth and well being of the child and it is associated with excellent survival (> 90%).
