Seroprevalence of hepatitis B and C viruses in moderate and severe COVID-19 inpatients: A cross-sectional study at a referral center in Mexico.

INTRODUCTION AND OBJECTIVES: The emergence of SARS-CoV-2, which causes the coronavirus disease (COVID-19) has caused a great impact on healthcare systems worldwide, including hepatitis B and C viruses screening and elimination programs. The high number of COVID-19 hospitalizations represent a great opportunity to screen patients for hepatitis B virus (HBV) and hepatitis C virus (HCV), which was the aim of this study. MATERIAL AND METHODS: Cross-sectional, retrospective study performed between April 2020 and 20201 at a referral center in Mexico dedicated to the care of adults with severe/critical COVID-19. We retrieved clinical, demographic, and laboratory results from each patient´s medical records, including antibodies against HCV (anti-HCV), HBV surface antigen (HBsAg), antibodies against the HBV core antigen (anti-HBcAg), and antibodies against HBsAg (anti-HBsAg). RESULTS: Out of 3620 patients that were admitted to the hospital, 24 (0.66%), 4 (0.11%), and 72 (1.99%) tested positive for anti-HCV, HBsAg, and anti-HBcAg, respectively. Of all seronegative patients, 954 (27%) had undetectable anti-HBsAg and 401 (12%) had anti-HBsAg at protective levels. Blood transfusion was the most relevant risk factor. Only 9.7% of the anti-HBc positive, 25% of the HBsAg positive, and 52% of the anti-HCV positive were aware of their serological status. CONCLUSIONS: In this study we found a prevalence of anti-HCV of 0.66%, HBsAg in 0.11%, and isolated anti-HBcAg in 1.99%. We also found that HBV vaccination coverage has been suboptimal and needs to be reinforced. This study gave us a trustworthy insight of the actual seroprevalence in Mexico, which can help provide feedback to the Hepatitis National Elimination Plan.

Pharmacologic management of patients with hepatic and pancreatic diseases that involve immunosuppressive therapies. Position statement within the framework of the SARS-CoV-2 (COVID-19) pandemic. / Manejo farmacológico de pacientes con enfermedades hepáticas y pancreáticas que involucran terapias inmunosupresoras. Posicionamiento en el marco de la pandemia de SARS-CoV-2 (COVID-19).

The coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus2 (SARS-CoV-2) virus. COVID-19 affected more than 6million persons worldwide in fewer than 4 months, after the report of the first cases in China in December 2019. The relation of the disease caused by SARS-Cov-2 to immunosuppressive treatment used in different gastrointestinal disorders is uncertain, resulting in debate with regard to suspending immunosuppressive therapy to improve infection outcome. Said suspension implies the inherent risk for graft rejection or autoimmune disease exacerbation that can potentially worsen the course of the infection. Based on the presently available evidence, a treatment stance has been established for patients with gastrointestinal diseases that require immunosuppressive therapy.

Resumen La enfermedad por coronavirus 2019 (COVID-19) es causada por el virus de Síndrome Respiratorio Agudo Grave - Coronavirus 2 (SARS-CoV-2). COVID 19 afectó cerca de 2 millones de personas en todo el mundo en menos de 4 meses posterior al reporte de los primeros casos en China en diciembre 2019. La relación que guarda la enfermedad por SARS-Cov-2 con el tratamiento inmunosupresor utilizado en diversos trastornos gastrointestinales es incierta, esto genera el debate sobre suspender el tratamiento inmunosupresor para mejorar el pronóstico de la infección, lo cual incluye el riesgo inherente de rechazo de injerto o agudización de enfermedades autoinmunes que potencialmente pudieran agravar el curso de la infección. En base a la evidencia disponible se logra establecer una postura de tratamiento en pacientes con enfermedades gastrointestinales que requieren terapia inmunosupresora.
