Hydroxychloroquine in a G6PD-Deficient Patient with COVID-19 Complicated by Haemolytic Anaemia: Culprit or Innocent Bystander?

Abstract

Hydroxychloroquine has been used worldwide as a first-line treatment for patients hospitalized with COVID-19. Little is known about COVID-19 and its effects on patients with congenital red blood cell disorders. We report a case of haemolytic anaemia in a 32-year-old patient and a fortuitous highlighting of G6PD deficiency. We reviewed the literature to assess the risk of hydroxychloroquine use in this context.

Learning points: A rapid drop in haemoglobin in COVID-19 patients should alert physicians to test for haemolytic anaemia and enzymopathies.Our review of the literature shows that use of hydroxychloroquine is safe in G6PD-deficient patients.
