[Weil-Vasil'ev disease in the Burgas region]

31 patients with Weil-Vassilev's disease are discussed epidemiologically, clinically and by laboratory indices. The disease is predominantly professional, the minors prevailing. Clinically it is manifested by acute onset, febrile and toxiinfectious syndrome and various organ manifestations--liver, renal, meningeal. The hepato-renal syndrome is leading (64.5%). The patient's fate is determined by the renal failure mainly. Hemodialysis and proper intensive care play a decisive role in the treatment. Since the patients are admitted to hospital late, on the sixth day mean, the antibiotic treatment is of less importance. The disease is not well known by the physicians and the initial diagnosis is usually wrong.
