Measles-Associated Severe Pneumonia in a Patient with HBeAg-Negative Chronic Hepatitis B: A Case Report

Abstract

Background: Every year, approximately 800,000 people die from liver diseases associated with hepatitis B virus (HBV) infection. Complications outside the liver are common, such as fungal lung infections and viral infections. These complications may be associated with poor immune function, thus making clinical treatment difficult and increasing the risk of death. Therefore, HBV-infection-related liver diseases are worthy of clinical attention and further research. Case summary: We report a case of HBeAg-negative chronic hepatitis B in which the patient received entecavir as an anti-HBV treatment after liver dysfunction. During the treatment, the patient was diagnosed with measles and severe viral pneumonia. After comprehensive treatment, including active antiviral medications and mechanical ventilation, the patient recovered and was discharged. Conclusion: HBV infection causes liver damage, affects immune function, and is likely to be associated with viral infections such as measles. Consequently, infections may lead to complications, such as severe viral pneumonia, that endanger patients’ lives. To decrease complications and mortality, better understanding of the disease is necessary to enable early diagnosis.
