Nonalcoholic fatty liver disease as a risk factor for cytomegalovirus hepatitis in an immunocompetent patient: A case report

BACKGROUND: Almost 80 percent of adults in the United States have had cytomegalovirus (CMV) infection by age 40. The number of symptomatic CMV hepatitis cases has been increasing along with non-alcoholic fatty liver disease (NAFLD) cases in the United States that is estimated to be 25 percent of the population. In this paper, we try to link these two entities together. CASE SUMMARY: In this case report, we describe a young female who presented with fever, nausea, and vomiting who was found to have NAFLD and CMV hepatitis that was treated supportively. CONCLUSION: In this case report, we describe NAFLD as a risk factor for CMV hepatitis and discuss the possible impact on clinical practice. We believe, it is essential to consider NAFLD and it’s disease mechanisms’ localized immu-nosuppression, as a risk factor of CMV hepatitis and severe coronavirus disease 2019 infection.
