Abstract

Leptospirosis is the most common zoonosis in the world but remains underreported, owing to protean manifestations and ignorance about the disease among health care providers in Taiwan. From September 2000 to March 2006, surveillance of 455 patients with multiple organ dysfunction syndrome with unclear cause or clinical suspicion of leptospirosis was performed. Diagnosis was further confirmed by microscopic agglutination test or isolation of Leptospira. Cases were classified as excluded based on confirmed etiology other than leptospirosis or negative paired serologic test. Forty-two patients were confirmed as having leptospirosis, which accounted for 9.2% of total patients with multiple organ dysfunction syndrome. Forty-nine excluded cases were identified for a case-control analysis for clinical distinction. The most common presentations of leptospirosis were fever (97.6%), acute kidney injury (85.7%), and jaundice (61.9%). The leptospirosis group showed lower urine specific gravity (cutoff value, 1.0145) and enlarged kidney size (cutoff value, 11.05 cm) as compared with the excluded cases by multivariate logistics regression. Delayed antibiotic administration prolongs the duration of hospitalization (R 2 = 0.486, P <0.01). No mortality has been found in the leptospirosis group after initiation in 2003 of rapid immunoglobulin M serology assay that showed considerably high sensitivity and specificity. Leptospirosis accounts for a salient cause of multiple organ dysfunctions in Taiwan. Early awareness of leptospirosis by distinct presentations, followed by prompt antibiotics therapy, can dramatically save the patients. The easily performed rapid immunoglobulin M serology assay is suitable as a rapid screening test for the diagnosis of leptospirosis.
