This study examined the clinical presentations and laboratory findings in serologically confirmed cases of leptospirosis.Patients and methods: The medical records of all hospitalized patients with presumptive and confirmed leptospirosis between June 2005 and May 2006 at the University Hospital of the West Indies were retrospectively reviewed.Results: There were five serologically confirmed cases of leptospirosis. The mean age of patients with leptospirosis was 57.33 ± 8.21 years (range 41–67 years); all were men exposed to contaminated water or soil, and most cases were diagnosed in November. The most common symptoms were fever, myalgia, nausea, vomiting, headache, abdominal pain, and arthralgia. Increase in the mean serum creatinine concentration in patients with leptospirosis (439.40 ± 129.18 µmol/L) was significant when compared with that in the controls (87.86 ± 4.72 µmol/L; P = 0.005). Four of the five patients with leptospirosis showed evidence of hematuria. All patients with leptospirosis showed evidence of hyperbilirubinemia, which was mostly direct hyperbilirubinemia. The mean concentration of total bilirubin was 291.40 ± 52.33 µmol/L in patients with leptospirosis when compared with 9.83 ± 1.28 µmol/L in controls (P < 0.001). Thrombocytopenia (platelet count
