A 35-year-old renal transplant patient with stable renal function developed an unexplained anaemia. Appropriate investigations proved non-diagnostic. Only when enalapril therapy was stopped did the anaemia reverse and haemoglobin levels returned to pre-treatment levels. An association between angiotensin-converting enzyme inhibitors and anaemia in patients with renal failure is becoming more evident. A literature review of this problem and its possible pathogenesis in patients with renal failure is given.
