[Leptospirosis (Weil's disease) in Augsburg].

HISTORY: Three unrelated patients presented within three months at the Central Hospital of Augsburg, Southern Germany, with jaundice of initially unknown etiology. Patient (Pt.) 1, a 51-year old man was admitted with a history of nausea, vomiting, diarrhea, jaundice and anuria. Pt. 2 was a 58-year-old man who had fever and shivering, and had developed jaundice after a fishing-trip to Canada. Pt. 3 was a 66-year-old woman who presented at the Emergency Unit with recently developed jaundice and pain in the right lateral epigastric area.

INVESTIGATIONS: Laboratory results showed elevated levels for bilirubin, CK, BUN, creatinine and low thrombocytes in patients 1 and 2. An elevated lipase level was found in Pt 1, while Pt 3 had an elevated bilirubin and thrombocytopenia. In Pt 1 and 2 active leptospirosis was diagnosed by serological tests. The third patient showed a subsided leptospirosis, the jaundice having been due to a histologically confirmed drug-associated hepatitis.

TREATMENT AND COURSE: Patients 1 and 2, who had active disease, showed the full-blown clinical picture of Weil's disease with jaundice, renal failure and thrombocytopenia. After administration of penicillin G and a third generation cephalosporin (ceftriaxone), respectively, all symptoms disappeared. The 66-year-old woman (Pt 3) developed pneumonia and died of multiple organ failure.

CONCLUSION

Leptospirosis is an important differential diagnosis in patients with recent onset of jaundice and acute renal failure. A detailed history may offer the crucial hint and serological tests provide proof. The clinical outcome mainly depends on starting antimicrobial therapy with penicillin G or a third generation cephalosporin as soon as practicable.
