Atypical imported loiasis characterised by recurrent anaemia in a patient from China.

In March, 2021, a 49-year-old man was admitted to The Fourth People's Hospital of Nanning (Nanning, China) with recurrent dizziness and fatigue that had persisted for more than 1 year. Physical examination revealed paleness on his face and a slightly yellow sclera. He had no hepatomegaly, but he had splenomegaly. His laboratory results showed a low haemoglobin concentration of 84 g/L, a normal blood eosinophil percentage of 3·1%, a high reticulocyte percentage of 4·6%, haemoglobinuria (score of 2+), a low haptoglobin concentration of 1·01 mg/dL (normal range 32–205 mg/dL), a high lactic acid dehydrogenase concentration of 750 U/L (normal range 120–160 U/L), and a high 3-hydroxybutyrate dehydrogenase concentration of 711 U/L (normal range 72–182 U/L).
