Liver Damage and Exposure to Toxic Concentrations of Endogenous Retinoids in the Pathogenesis of COVID-19 Disease: Hypothesis.

Viral Immunol 2021 May 13. Epub 2021 May 13.

Department of Ophthalmology and Pathology, University of Mississippi Medical Center, Jackson, Mississippi, USA.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has a marked tropism for the biliary tract; it damages the bile ducts and hepatocytes and can lead to liver decompensation, cirrhosis, and sepsis. The pathogenesis of liver damage and its association with damage to the lung, heart, and brain and to the other protean manifestations of COVID-19 disease are not fully understood. In particular, tissue damage from thinning and leaky blood vessels appears to result from an inflammatory response to the virus rather than the virus itself. Read More

Cholangiocyte Organoids as a Cell Source for Biliary Repair.

Transpl Int 2021 May 11. Epub 2021 May 11.

Department of Pathology, Division of Experimental Pathology, School of Medicine, University of Pittsburgh, Pittsburgh, PA, USA.

Preoccupied with the astounding regenerative capabilities and metabolic importance of hepatocytes in the liver, the role of the resident "plumbers" of the liver, the cholangiocytes, can be overlooked in comparison. Cholangiocytes form the ductal network which makes up the biliary tree and transports bile from the liver to the gallbladder for secretion into the intestine during digestion. Chronic accumulation of bile in the liver is cytotoxic, causing fibrosis and eventually leads to cirrhosis and liver failure. Read More

Practical approach for the diagnosis of biliary atresia on imaging, part 2: magnetic resonance cholecystopancreatography, hepatobiliary scintigraphy, percutaneous cholecysto-cholangiography, endoscopic retrograde cholangiopancreatography, percutaneous liver biopsy, risk scores and decisional flowchart.

Pediatr Radiol 2021 May 11. Epub 2021 May 11.

APHM, Equipe d'Accueil 3279 - IFR 125, Service d'Imagerie Pédiatrique et Prénatale, Hôpital Timone Enfants, Aix Marseille Univ, Marseille, France.

We aim to present a practical approach to imaging in suspected biliary atresia, an inflammatory cholangiopathy of infancy resulting in progressive fibrosis and obliteration of extrahepatic and intrahepatic bile ducts. Left untreated or with failure of the Kasai procedure, biliary atresia progresses to biliary cirrhosis, end-stage liver failure and death within the first years of life. Differentiating biliary atresia from other nonsurgical causes of neonatal cholestasis is difficult as there is no single method for diagnosing biliary atresia and clinical, laboratory and imaging features of this disease overlap with those of other causes of neonatal cholestasis.

Zhonghua Gan Zang Bing Za Zhi 2021 Mar;29(3):209-212

Department of Gastroenterology, Shanghai General Hospital, Shanghai Jiaotong University School of Medicine, Shanghai 200080, China.

Endoscopic retrograde cholangiopancreatography (ERCP) is the most direct and effective method for the diagnosis and treatment of biliary and pancreatic diseases. Compared with surgery, ERCP has the advantages of minimal trauma, shorter surgery time, fewer complications, and shorter hospital stay. Liver cirrhosis, as the advanced stage of liver disease, has reduced tolerance to surgical stresses, and complications such as hepatic encephalopathy, esophagogastric varices, and coagulation dysfunction may occur during the decompensated stage, which poses a challenge to ERCP, and thus increase the intraoperative risk and postoperative complications.
