Henoch-Schönlein purpura associated with acetaminophen and codeine.
We report a case of a relapse of Henoch-Schönlein Purpura (HSP) associated with intake of paracetamol (also known as acetaminophene) and codeine. A 69-year-old man presented with fever, gross hematuria, acute renal failure, palpable purpuric skin rash over the legs, feet and arms, arthralgias and abdominal discomfort. 1 week before he had started therapy with co-efferalgan (association of paracetamol and codeine) for cervical arthrosis. Blood test revealed increase in serum creatinine levels (2.6 mg/dl), CRP (375 mg/dl), with no thrombocytopenia or hypocomplementemia. Co-efferalgan was discontinued. Gross hematuria resolved in 2 days, purpuric rash disappeared in 10 days, renal function returned to normal after 2 weeks and abdominal pain and arthralgias improved on the following 2 - 3 weeks. An objective causality assessment in accordance with the Naranjo algorithm, revealed that the adverse drug reaction was probable between paracetamol/codeine and Henoch-Schönlein purpura. To our knowledge, and based on a medline search (up to 2005), we believe that this could be considered the first case of Henoch-Schönlein purpura, associated with intake of paracetamol and codein. Although this event could be considered rare, clinicians should to be aware of possible associations between HUS and the intake of paracetamol and/or codeine to provide an early therapeutic intervention and a close monitoring.
