Hepatitis A at the Hospital de Especialidades Centro Medico Nacional La Raza. Preliminary report.

Abstract

Introduction and Objectives: The hepatitis A virus in our country is an endemic disease with a benign course that presents in early stages of life, generating lasting immunity so that the frequency of presentation decreases in adulthood. Serious cases often occur at the extremes of life. We have observed an increase in cases of Hepatitis A requiring hospitalization with severe liver dysfunction.This study aimed to determine the clinical, biochemical, complications, and mortality characteristics of patients with acute hepatitis A virus admitted to a tertiary-level hospital. Materials and Patients: A descriptive, cross-sectional, retrospective, observational study was carried out in patients with acute hepatitis A virus hospitalized in the Gastroenterology service of the Hospital de Especialidades CMN La Raza from February 2022 to April 2023. Age, gender, clinical presentation, complications, and comorbidities were assessed. The results were analyzed with relative and central frequency measures to obtain percentages, mean, and arithmetic mean. Results: 31 patients were registered, 29 men (94%) and two women (6%). The average age was 35 years (18-56). 11 patients (35%) presented acute liver failure, and 1 case was a prolonged cholestatic atypical hepatitis. The most frequent complications presented during the hospital stay were the following: coagulopathy (INR>1.5) 64%, acute kidney injury 38%, anemia 35%, encephalopathy 35% (Table 1). Mortality was 13% (4 patients) due to acute liver failure and without comorbidities. The average of relevant biochemical alterations: AST 1849 U/L, ALT 2602 U/L, total bilirubin 18.24 mg/dL, creatinine 2.05 mg/dL, INR 2.56. (Table 2). 64% of patients had no comorbidities. The comorbidities found were cirrhosis, polycystic liver disease, essential thrombocytosis, multiple sclerosis, Evans syndrome, arterial hypertension, diabetes, obesity, dyslipidemia and HIV. Conclusions: The presence of acute liver failure and mortality in our population was high in comparison to what has been reported in the international literature. Coagulation disorders, acute kidney injury and anemia were the most frequent complications in our cases of hepatitis A. It was relevant that most of the patients were <40 years old and 94% were male.
