title: [Leptospirosis after a stay in Thailand].
abstract: METHODS
  A 35-year-old man was admitted to our hospital with chills, headache, pain in the calves for five days and a bloody sputum. The day before he had returned from a 4-week trip to the north of Thailand. There he had participated in hiking trips and walked sometimes over wet fields with small skin injuries on his feet. The admission examination was uneventful except fever as high as 39 Celsius, particularly no rash, no conjunctivitis, no spleno- or hepatomegaly and no palpable lymph nodes could be noted.
  
  
  METHODS
  An x-ray of the chest showed confluent opacities, a bronchoscopy revealed diffuse alveolar hemorrhagy. Blood chemistry showed elevated liver enzymes, elevated kidney retention parameters and an increased C-reactive protein. An extended microbiological diagnostic procedure showed elevated antibody titers for leptospira and a PCR detected leptospira-DNA, representing acute leptospirosis.
  
  
  RESULTS
  After initiation of an antibiotic regimen including ceftriaxone and erythromycine the fever resolved immediately and the general condition improved. The patient could be discharged after two weeks in a good physical condition.
  
  
  CONCLUSIONS
  The constellation of flu-like symptoms, hepatitis and nephritis, eventually escorted by bloody sputum, may suggest leptospirosis.
