COVID-19, caused by severe acute respiratory syndrome coronavirus 2 infection, has caused the ongoing global pandemic. Initially considered a respiratory disease, it can manifest with a wide range of complications (gastrointestinal, neurological, thromboembolic and cardiovascular) leading to multiple organ dysfunction. A range of immune complications have also been described. We report the case of a 57-year-old man with a medical history of hypertension, prediabetes and beta thalassemia minor, who was diagnosed with COVID-19 and subsequently developed fatigue and arthralgias, and whose blood work showed hyperferritinemia, elevated liver enzymes (AST/ALT/GGT), hypergammaglobulinemia, anti-smooth muscle antibody, anti-mitochondrial antibody, and anti-double-stranded DNA antibodies. The patient was diagnosed with autoimmune hepatitis-primary biliary cholangitis overlap syndrome triggered by COVID-19. To our knowledge, this is the first such case reported. LEARNING POINTS: COVID-19 can precipitate a wide range of immune complications; we report a case of autoimmune hepatitis-primary biliary cholangitis overlap syndrome triggered by COVID-19.Clinicians should be aware of this unusual manifestation of COVID-19 so that prompt and appropriate diagnostic and therapeutic interventions can be initiated if the syndrome is suspected or confirmed.Our case further suggests the necessity for continued and regular follow-up of patients who have recovered from COVID-19 in order to uncover the long-term effects of the novel virus.
