Progressive familial intrahepatic cholestasis (PFIC) and benign recurrent intrahepatic cholestasis (BRIC) are two rare autosomal recessive disorders, characterized by cholestasis. They are related to mutations in hepatocellular transport system genes involved in bile formation. The differentiation between PFIC and BRIC is based on phenotypic presentation: PFIC is a progressive disease, with evolution to end-stage liver disease. BRIC is characterized by intermittent recurrent cholestatic episodes, with irresistible pruritus, mostly without evident liver damage. Between symptomatic periods, patients are completely asymptomatic. In this article, a short overview of the aetiology, the clinical and diagnostic characteristics and the therapy of both PFIC and BRIC are given.

    ABSTRACT: Introduction: The liver is the central place for the metabolism of drugs and other xenobiotics. In the liver cell, oxidation and conjugation of compounds take place, and at the same time, bile formation helps in extrusion of these compounds via the biliary route. A large number of transporters are responsible for drug uptake into the liver cell and excretion into bile or efflux to the sinusoidal blood. Areas covered: Genetic variants of these transporters and their transactivators contribute to changes in drug handling and are also responsible for cholestatic syndromes of different severity. This review summarizes the current knowledge regarding the influence of these genetic changes. The review covers progressive hereditary cholestatic syndromes as well as recurrent or transient cholestatic syndromes such as drug-induced liver injury, intrahepatic cholestasis of pregnancy, and benign recurrent intrahepatic cholestasis. Expert opinion: Polymorphisms in transporter genes are frequent. For clinically relevant cholestatic syndromes, it often requires a combination of genetic variants or acquired triggers such as pregnancy or drug treatment. In combination with other pathogenetic aspects, genetic variants in drug transporters may contribute to our understanding of not only cholestatic diseases such as primary sclerosing cholangitis or primary biliary cirrhosis, but also the natural course of chronic liver disease in general.

    ABSTRACT: This article discusses common liver diseases in the adolescent. Briefly reviewed is the evaluation of the adolescent with new-onset liver enzyme elevation. Then the article discusses common liver diseases, such as nonalcoholic fatty liver disease, hepatitis, metabolic disease, biliary atresia, cystic fibrosis, and inherited disorders of cholestasis. Finally, a management approach to the adolescent with liver disease is outlined, noting the challenges that must be addressed to effectively care for not only liver disease in the adolescent but also the patient as a whole.

    ABSTRACT: Hepatic cirrhosis is an important cause of morbidity and mortality. An unusual case of cirrhosis and portal hypertension in an 18-year-old patient secondary to Progressive Intrahepatic Cholestasis is discussed. The clinical and biochemical findings are discussed and a clinical approach to determining the underlying etiology of cirrhosis is outlined. Significant complications of portal hypertension include ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, varices, and hepatic encephalopathy. A clinical approach to these complications of cirrhosis is presented. Progressive Familial Intrahepatic Cholestasis (PFIC) is a rare congenital metabolic abnormality. There are 3 subtypes and Type 3 PFIC commonly presents in late adolescence and early adulthood. Clinical and laboratory findings as well as management for the condition are described.
