Post-COVID-19 Secondary Sclerosing Cholangitis: A Rare but Severe Condition with no Treatment Besides Liver Transplantation.

BACKGROUND The incidence of abnormal liver function, mainly aspartate aminotransferase and alanine aminotransferase elevations, in patients with COVID-19 is not uncommon, but persistent liver damage after the acute phase of the disease is uncommon and has been recently recognized as a new entity named post-COVID-19 cholangiopathy. CASE REPORT We report a clinical case with progressive cholestatic disease following severe COVID-19. AST and ALT peaked at hospital admission and while its serum concentration went down, bilirubin and cholestatic liver enzymes started to increase, reaching the maximum at day 122. Magnetic resonance imaging (MRI) revealed a diffuse irregularity of intra- and extrahepatic bile ducts, with multiple focal strictures alternating with mild focal dilations of the biliary tree, suggesting a sclerosing cholangiopathy. A transjugular liver biopsy showed a prominent bile ductular reaction, cholangiocyte injury, inflammatory infiltrate rich in neutrophils, biliary infarctions, marked cholestasis, and portal fibrosis, suggesting the diagnosis of post-Covid-19 secondary sclerosing cholangitis. The patient evolved with a continuous deterioration of liver functions, but liver transplantation was not performed due to his poor clinical condition. CONCLUSIONS Post-COVID-19 SSC is a severe disease with no effective clinical treatment and has liver transplantation as the only treatment for a few selected patients.

Hemorragia digestiva alta varicosa: relatório do 1º consenso da Sociedade Brasileira de Hepatologia / Varicel bleeding: consensus meeting report from the brazilian society of hepatology

Nas últimas duas décadas, foi observada redução importante na mortalidade associada ao primeiro sangramento varicoso, que vem sendo atribuída à melhoria na assistência ao paciente cirrótico e à abordagem multidisciplinar do paciente com hemorragia digestiva alta varicosa (HDAV), particularmente por emergencistas, hepatologistas, gastroenterologistas, endoscopistas e intensivistas. Visando estabelecer recomendações para o manejo da HDAV, a Sociedade Brasileira de Hepatologia (SBH) realizou reunião de consenso para elaboração de documento a ser utilizado como orientação de conduta médica. Dentro da sistemática utilizada, foi criada pela SBH uma comissão organizadora composta por quatro membros que escolheram 27 pesquisadores, representando as diversas regiões do país, para serem moderadores ou expositores dos tópicos relacionados à prevenção, diagnóstico e tratamento da HDAV. Todos os tópicos foram abordados de acordo com o grau de evidência científica disponível. As recomendações foram elaboradas em reunião após ampla discussão com os membros da comissão organizadora, expositores, moderadores e participantes da reunião do consenso, ficando a cargo da comissão organizadora a redação do documento final. A reunião do consenso ocorreu em Salvador em 06 de maio de 2009 e esta publicação exibe as principais conclusões do consenso organizadas sob a forma de resumo da literatura médica seguido pelas recomendações da SBH.

In the last decades, several improvements in the management of variceal bleeding have resulted in a significant decrease in morbidity and mortality of cirrhotis with bleeding varices. Progress in the multidisciplinary approach to the patient with variceal blleding has led to a better management of this disease by critical care physicians, hepatologists, gastroenterologists, endoscopists, radiologists and surgeons. In this respect, the Brazilian Society of Hepatology has, recently, sponsored a consensus meeting in order to draw evidence-based recommendations on the management of these difficult-totreat subjects. An organizing committee comprised of four people was elected by the Governing Board and was responsible to invite 27 researchers from distinct regions of the country to make a systematic review of the subject and to present topics related to variceal bleeding, including prevention, diagnosis, management and treatment, accoding to evidence-based medicine. After the meeting, all participants were held together for discussion of the topics and the elaboration of the aforementioned recommendations. The organizing committee was responsible for writing the final document. The meeting was held at Salvador, May 6th, 2009 and the present manucrispt is the summary of the systematic review that was presented during the meeting organized in topics followed by the reccomendations of the Brazilian Society of Hepatology.

Association of polymorphisms of glutamate-cystein ligase and microsomal triglyceride transfer protein genes in non-alcoholic fatty liver disease.

BACKGROUND AND AIMS: Although the metabolic risk factors for non-alcoholic fatty liver disease (NAFLD) progression have been recognized, the role of genetic susceptibility remains a field to be explored. The aim of this study was to examine the frequency of two polymorphisms in Brazilian patients with biopsy-proven simple steatosis or non-alcoholic steatohepatitis (NASH): -493 G/T in the MTP gene, which codes the protein responsible for transferring triglycerides to nascent apolipoprotein B, and -129 C/T in the GCLC gene, which codes the catalytic subunit of glutamate-cystein ligase in the formation of glutathione. METHODS: One hundred and thirty-one biopsy-proven NAFLD patients (n = 45, simple steatosis; n = 86, NASH) and 141 unrelated healthy volunteers were evaluated. Genomic DNA was extracted from peripheral blood cells, and the -129 C/T polymorphism of the GCLC gene was determined by restriction fragment length polymorphism (RFLP). The -493 G/T polymorphism of the MTP gene was determined by direct sequencing of the polymerase chain reaction products. RESULTS: The presence of at least one T allele in the -129 C/T polymorphism of the GCLC gene was independently associated with NASH (odds ratio 12.14, 95% confidence interval 2.01-73.35; P = 0.007), whereas, the presence of at least one G allele in the -493 G/T polymorphism of the MTP gene differed slightly between biopsy-proven NASH and simple steatosis. CONCLUSION: This difference clearly warrants further investigation in larger samples. These two polymorphisms could represent an additional factor for consideration in evaluating the risk of NAFLD progression. Further studies involving a larger population are necessary to confirm this notion.

Evaluation of reagent strips for ascitic fluid leukocyte determination: is it a possible alternative for spontaneous bacterial peritonitis rapid diagnosis?

In order to evaluate the accuracy of a urine reagent dipstick (Multistix 10SG) to determine ascitic fluid leukocyte count, we prospectively studied 106 cirrhotic patients from April 2003 to December 2004, in two different centers (Federal University of São Paulo - UNIFESP-EPM and Federal University of Juiz de Fora - HU-UFJF) for the rapid bedside diagnosis of spontaneous bacterial peritonitis. The mean age 54 +/- 12 years, there was a predominance of males (eighty-two patients, 77%), and alcohol was the most frequent etiology (43%). Forty-four percent of patients were classified as Child B and fifty-one as Child C (51%). Abdominal paracentesis was performed both in outpatient and inpatient settings and the Multistix 10SG was tested. Eleven cases of spontaneous bacterial peritonitis were identified by means of polymorphonuclear count. If we considered the positive Multistix 10SG result of 3 or more, the sensitivity, specificity, positive and negative predictive value were respectively 71%, 99%, 91% and 98%. With a positive reagent strip result taken as grade 2 (traces) or more, sensitivity was 86% and specificity was 96% with positive and negative predictive values of 60% and 99%, respectively. Diagnostic accuracy was 95%. We concluded that the use of a urine reagent dipstick (Multistix 10SG) could be considered a quick, easy and cheap method for ascitic fluid cellularity determination in SBP diagnosis.
