Liu Y, Zhu P, Tian J. Case report: Rare genetic liver disease - a case of congenital hepatic fibrosis in adults with autosomal dominant polycystic kidney disease. Front Med (Lausanne) 2024; 11:1344151.

Abstract
Congenital hepatic fibrosis (CHF) is considered to be a rare autosomal recessive hereditary fibrocystic liver disease, mainly found in children. However, cases of adult CHF with autosomal dominant polycystic kidney disease (ADPKD) caused by PKD1 gene mutation are extremely rare. We report a 31-year-old female patient admitted for esophageal and gastric variceal bleeding. Physical examination revealed significant splenomegaly, biochemical tests showed a slight increase in liver enzymes, and a decrease in platelet count. Imaging examinations showed significant dilatation of the common bile duct and intrahepatic bile ducts, as well as multiple renal cysts. Liver biopsy revealed enlarged portal areas, bridging fibrosis, and numerous variably shaped small bile ducts. Genetic testing identified two unique mutations in the PKD1 gene, identified as biallelic mutations compound heterozygous mutations composed of a mutation inherited from the father (c.8296 T > C) and one from the mother (c.9653G > C). Based on multiple test results, the patient was diagnosed with the portal hypertension type CHF associated with ADPKD. During her initial hospital stay, the patient underwent endoscopic treatment for gastrointestinal bleeding. To date, the patient has recovered well. Moreover, a significant reduction in varices was observed in a gastroscopy examination 18 months later.

Abstract
A variety of cystic and fibrocystic lesions can occur in the liver, which may be single or multiple and etiologically can be acquired or have genetic underpinnings. Although the morphology of ductal plate development and various associated malformations has been well described, the genetic etiologies of many of these disorders are still poorly understood. Multiple clinical phenotypes in the liver are proposed to originate from ductal plate malformations: congenital hepatic fibrosis, Caroli's disease, Von Meyenburg complex, and the liver cysts of autosomal dominant polycystic kidney and liver diseases. Although many of the patients with these disorders, particularly with isolated liver involvement remain asymptomatic, some develop portal hypertension or symptoms from cyst enlargement. Development of hepatocellular malignancy is a risk in a small subset. Recent advances have made it now possible for some of these phenotypes to be genetically defined, and intriguingly animal models of adult polycystic liver disease suggest that abnormal organ development is not required. This review describes the current understanding, genetic underpinning, and key clinicopathologic and imaging features of these fibropolycystic liver diseases.

Abstract
BACKGROUND Congenital hepatic fibrosis (CHF) is a rare autosomal recessive disorder characterized by variable degrees of periportal fibrosis and malformation of bile ducts. CHF is generally accompanied by a variety of conditions or syndromes with other organ involvement.
CASE SUMMARY We report a 5-year-4-month-old Chinese boy with congenital hypothyroidism (CH) diagnosed with CHF. The patient was diagnosed with CH by a newborn screening test and has since been taking levothyroxine. He has developed normally without neurocognitive deficits. Abnormal liver function was observed in the patient at the age of 4 years and 11 mo, and elevated levels of liver function indices were persistent for 5 mo. Radiological imaging indicated hepatospleno-megaly without narrowing of the portal vein but dilated splenic vein. A liver biopsy confirmed the pathological features of CHF. Genetic testing revealed two novel homozygous mutations, namely, c.2141-3T>C variant in PKHD1 related to CHF and c.2921G>A (p.R974H) in DUOX2 related to CH. The patient was treated with compound glycyrrhizin tablet, ursodeoxycholic acid, and levothyroxine after diagnosis. The patient achieved a favorable clinical outcome during a follow-up period of over 2 years.
CONCLUSION Herein, we report the first case of a Chinese boy with comorbidity of CHF and CH, carrying both PKHD1 gene and DUOX2 gene novel mutations. Liver biopsy and genetic testing should be considered for the diagnosis of coexistent liver disease in CH patients with unexplained abnormal liver function.

Abstract
Fibropolycystic liver disorders (FLD) arise from abnormal development of the ductal plate and are classified according to the size of the affected hepatobiliary duct. Congenital hepatic fibrosis (CHF) has small duct involvement characterized by a variable degree of periportal fibrosis and hyperplasia without affecting the liver’s architecture. Caroli’s disease (CD) is a rare autosomal recessive disorder with a prevalence of one case per 1,000,000 people and is characterized by cystic dilation of large intrahepatic ducts. When the disease presents with congenital hepatic fibrosis, it is referred to as Caroli’s syndrome (CS). Patients are usually diagnosed around the age of 20 with episodes of cholangitis, portal hypertension or hepatomegaly. We present the case of a two-year-old male with a previous history of autosomal recessive polycystic kidney disease (ARPKD) who presented to the emergency room with variceal bleeding secondary to portal hypertension. The physical examination showed an acutely ill-looking boy, with evident paleness and distended abdomen. Past medical history was negative for previous gastrointestinal bleeding or episodes of cholangitis. An upper gastrointestinal endoscopy was performed, showing esophageal varices secondary to portal hypertension. Imaging studies revealed hepatosplenomegaly, alterations in liver echogenicity, and dilated saccular bile ducts affecting both liver lobes without observing any apparent obstruction, highly suggestive of CD. A liver biopsy revealed nodular liver tissue with marked fibrosis between nodules, which confirmed the presence of CHF. Both kidneys were increased in size, hyperechoic and with loss of corticomedullary differentiation. FLD commonly present with coexisting hepatobiliary and renal alterations. Therefore, starting at the time of initial diagnosis, all patients with ARPKD should be evaluated to detect liver abnormalities due to the high association. Despite the rarity of CS, especially in early childhood, the association between ARPKD and FLD is well documented. So if this clinical presentation arises, CS should be suspected.

Natural Sulfur-Containing Compounds: An Alternative Therapeutic Strategy against Liver Fibrosis. Cells 2019; 8:cells8111356.

Abstract
Liver fibrosis is a pathophysiologic process involving the accumulation of extracellular matrix proteins as collagen deposition. Advanced liver fibrosis can evolve in cirrhosis, portal hypertension and often requires liver transplantation. At the cellular level, hepatic fibrosis involves the activation of hepatic stellate cells and their transdifferentiation into myofibroblasts. Numerous pro-fibrogenic mediators including the transforming growth factor-β1, the platelet-derived growth factor, endothelin-1, toll-like receptor 4, and reactive oxygen species are key players in this process. Knowledge of the cellular and molecular mechanisms underlying hepatic fibrosis development need to be extended to find novel therapeutic strategies. Antifibrotic therapies aim to inhibit the accumulation of fibrogenic cells and/or prevent the deposition of extracellular matrix proteins. Natural products from terrestrial and marine sources, including sulfur-containing compounds, exhibit promising activities for the treatment of fibrotic pathology. Although many therapeutic interventions are effective in experimental models of liver fibrosis, their efficacy and safety in humans are largely unknown. This review aims to provide a reference collection on experimentally tested natural anti-fibrotic compounds, with particular attention on sulfur-containing molecules. Their chemical structure, sources, mode of action, molecular targets, and pharmacological activity in the treatment of liver disease will be discussed.
