Abstract
HISTORY: A 40-year-old teacher fell ill one week after returning from a two weeks back-packing trip to Thailand and Laos. He developed high fever, severe headache, myalgias and a conjunctivitis. INVESTIGATIONS: CRP and liver enzymes were elevated. The patient developed acute renal failure. Total leucocyte count was normal but the differential count showed an extreme left shift. Imaging procedures revealed hepato-splenomegaly and enlarged kidneys. TREATMENT, COURSE AND DIAGNOSIS: The patient was treated with moxifloxacin and ceftriaxon based on the initial suspicion of a severe infection potentially due to leptospirosis. This treatment led to a rapid improvement of the patient's condition and also of the laboratory findings. Leptospirosis could be confirmed by the seroconversion of specific antibodies to L. grippotyphosa 2 1/2 weeks after onset of complaints (initial serology negative). CONCLUSIONS: In febrile travelers returning from Southeast Asia, leptospirosis has to be considered especially in case of severe headache, myalgias, elevated liver enzymes and renal failure and a history of close contact to potentially contaminated water (rivers, lakes). Diagnosis is confirmed by the detection of specific antibodies.
