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

Zhonghua Gan Zang Bing Za Zhi 2021 Apr;29(4):377-380

Department of Hepatobiliary, The Second Affiliated Hospital of Chongqing Medical University, Chongqing 400010, China.

Transarterial chemoembolization is the first choice for patients with advanced stage liver cancer who are not apt for surgical resection. In clinical practice, rare and serious complications occur occasionally, and bile duct injury is one of the complications after transarterial chemoembolization. Therefore, understanding its mechanism and high-risk factors can reduce the occurrence of bile duct injury, and early detection and treatment can significantly improve the prognosis. Read More

Antioxidants resveratrol and SkQ1 attenuate praziquantel adverse effects on the liver in Opisthorchis felineus infected hamsters.

Acta Trop 2021 May 9:105954. Epub 2021 May 9.

Institute of Cytology and Genetics, Siberian Branch of Russian Academy of Sciences, 10 Lavrentiev Ave., Novosibirsk 630090, Russia; Department of Natural Sciences, Novosibirsk State University, 2 Pirogova Str., Novosibirsk 630090, Russia; Institute of Molecular Biology and Biophysics, 2/12, Timakov Str., Novosibirsk, 630117, Russia. Electronic address:

Anthelmintic praziquantel (PZQ) is the drug of the choice for opisthorchiasis, schistosomiasis and other trematodiases therapy for several decades. Despite its good therapeutic performance and effective control of trematode infections, PZQ has some shortcomings; its inability to counteract disease sequelae necessitates novel therapeutic strategies. Testing of antioxidants that have proven themselves in clinical practice, in combination with this anthelmintic drug, offers new opportunities for developing alternatives to PZQ monotherapy.

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.

Continuous suture is a risk factor for benign hepaticojejunostomy stenosis after pancreatoduodenectomy in patients with a non-dilated bile duct.

HPB (Oxford) 2021 Apr 27. Epub 2021 Apr 27.

Department of Gastroenterological Surgery, Aichi Cancer Center Hospital, Kanokoden 1-1, Chikusa-ku, Nagoya, Japan.

Degradable magnesium implants inhibit gallbladder cancer.

Acta Biomater 2021 May 5. Epub 2021 May 5.

State Key Laboratory of Metal Matrix Composites, School of Materials Science and Engineering, Shanghai Jiao Tong University, Shanghai 200240, China; Suzhou Origin Medical Technology Co. Ltd., Suzhou, Jiangsu 215513, China. Electronic address:

Gallbladder cancer can be difficult to detect in its early stages and is prone to metastasize, causing bile duct obstruction, which is usually treated by stent implantation in clinic. However, the commonly used biliary stents are non-degradable, which not only prone to secondary blockage, but also need to be removed by secondary surgery. Biodegradable magnesium (Mg) is expected to one of the promising candidates for degradable biliary stents due to its excellent physicochemical property and biocompatibility. Read More
