Abstract

COVID-19 infection and hereditary haemochromatosis (HH) have something in common; the disease course can be monitored with ferritin levels. Throughout the pandemic, physicians have looked for markers to help predict disease severity. Ferritin levels are commonly used to predict and monitor disease severity in hospitalised patients with COVID-19. While ferritin is elevated as part of the acute-phase reaction in response to infection, it can also be elevated due to iron overload. We report a case of undiagnosed, asymptomatic HH that was unveiled after COVID-19 infection via monitoring for resolution of ferritin levels that were found to be extremely elevated during a moderate COVID-19 infection. This diagnosis allowed the patient to initiate phlebotomy treatment before symptoms of HH arose.
