Summary: This study aims to improve the accuracy of the diagnosis of familial progressive intrahepatic cholestasis type 3 (PFIC3). Through the analysis of clinical records, laboratory tests, liver morphology, and molecular genetics in four PFIC3 patients, it was found that MDR3 immunohistochemistry and molecular genetic analyses of ABCB4 are essential for the accurate diagnosis of PFIC3.

Summary: The study evaluated the effects of odevixibat, an ileal bile acid transporter inhibitor, versus placebo in children with PFIC. The results showed that odevixibat effectively reduced pruritus and serum bile acids compared to placebo, and it was generally well-tolerated.

Summary: In this study, we reported two novel variants of the ABCB11 gene in a PFIC2 infant. We confirmed the splicing effects of these variants and designed an ASOs that successfully rescued the splicing defect. These findings expand the genotype of PFIC2 and provide evidence for a therapeutic approach for PFIC2 patients carrying intronic variants.

Summary: The homozygous mutation of SEMA7A(R145W) leads to intrahepatic cholestasis in both mice and children, with further studies showing that this mutation affects the expression of hepatic bile acid transporters and export pumps.

Summary: Progressive familial intrahepatic cholestasis type 3 (PFIC-3) is a rare autosomal recessive disorder with poor prognosis. This study reports a case of a 16-year-old male with acute episodes of jaundice and pruritus, which progressed to end-stage liver disease. Gene testing identified two missense mutations in the ABCB4 gene, one of which is a novel heterozygous mutation. Liver transplantation resulted in significant improvement of symptoms, confirming the diagnosis of PFIC-3.

Summary: Odevixibat, an IBAT inhibitor, is effective for treating pruritus in children with PFIC type 1 and 2. However, there is a lack of studies on the efficacy of Odevixibat in children with different subtypes of PFIC.

Summary: Idiosyncratic Drug-Induced Liver Injury (iDILI) is a significant health challenge, accounting for a high percentage of hepatitis and acute fulminant hepatic failure cases. It has been found that approximately 30% of iDILI cases are cholestatic, with drugs inhibiting specific transport proteins responsible for bile salt export and bile acids' metabolism and transport. Understanding the molecular pathways and links with familial intrahepatic cholestasis is crucial in identifying the main cholestasis-inducing drugs.

Summary: A case of low-gamma-glutamyltranspetidase cholestasis in a Brazilian child was found to be associated with a mutation in the USP53 gene. The patient initially presented with jaundice and hypocholia at 10 days old, and later developed cholelithiasis and intracranial hemorrhage. At 18 months old, the patient no longer had jaundice but experienced moderate pruritus, with genetic testing revealing a novel homozygous mutation in the USP53 gene.

Summary: The study presents a case of a boy with severe intrahepatic cholestasis and a homozygous mutation in NR1H4. Although the boy showed good liver function after liver transplantation, he eventually died from an acute infection one year post-transplantation. The study suggests that patients with FXR deficiency may respond well to liver transplantation without developing allograft steatosis.

Summary: Progressive familial intrahepatic cholestasis (PFIC) is a rare genetic disorder characterized by defects in biliary epithelial transporters. The disease mainly presents as low gamma-glutamyltransferase cholestasis. USP53 has been identified as a novel gene associated with PFIC. This study reports a case of late-onset PFIC in a 21-year-old Korean male patient, who showed improvement in symptoms after treatment.

Summary: This study presents the long-term outcomes after liver transplantation for PFIC1, with a focus on liver function and extrahepatic manifestations. The results show excellent patient and graft survival rates, low complication rates, and minimal impact on graft function. Further multicenter studies are needed to better understand the clinical presentation and courses after liver transplantation for PFIC1.

Summary: The study revealed a correlation between post-LT outcomes in PFIC-1 patients with ATP8B1 genotypes and extrahepatic manifestations, especially intestinal function. Further research into this correlation could help identify patients who will achieve favorable post-LT outcomes.
