The importance of "His" story.

A 73-year-old previously healthy man presented with a 3-day history of rigours, abdominal pain, diarrhoea, haemoptysis and myalgia. He had not been abroad recently, but reported being a farmer and having had a recent rat infestation. Laboratory investigations revealed acute kidney failure, deranged liver function tests, raised C reactive protein and a chest CT revealed bilateral ground-glass opacities. This presentation was consistent with icteric leptospirosis which was confirmed by serological testing. Following haemofiltration and the administration of antibiotics the patient made an excellent recovery from his leptospirosis. 2014 BMJ Publishing Group Ltd.
