Here’s an interesting case. An adult with what appears to be an aplastic crisis. The white cell count is something of a red herring – the patient is known to have long-standing chronic lymphocytic leukaemia.
The salient feature here is the low haemoglobin and reticulocyte count. Utterly at odds with previous findings, but totally in keeping with the clinical picture. The cause of the anaemia – parvo virus infection.
A search of the internet shows that parvo virus is not an uncommon cause of anaemia in patients with a range of diseases. For myself (who sees all of health care being based around red cells, white cells and platelets) the message is that I need to broaden my horizons…
