Leptospirosis is a zoonotic disease frequently found in Indonesia, with clinical presentations ranging from asymptomatic cases to severe conditions such as acute kidney injury (AKI), also known as Weil’s disease. In urban areas like Jakarta, the incidence of leptospirosis remains relatively high, particularly among individuals with occupational or environmental exposure to rats and contaminated environments
This descriptive study was conducted on patients diagnosed with leptospirosis at Tarakan General Hospital, Jakarta, from 2022 to 2025. The study assessed patient demographics, occupational background, history of exposure, clinical and laboratory manifestations, kidney involvement, and in-hospital outcomes including the need for hemodialysis and mortality.
Out of 34 leptospirosis patients confirmed positive for Leptospirosis IgM antibodies, the majority of patients were male (82.4%), with an average age of 51.5 years. The occupational backgrounds of patients diagnosed with leptospirosis in this study were diverse. The most common occupations were laborers (29.4%) and sanitation workers (23.5%), indicating a higher risk among individuals with frequent exposure to potentially contaminated environments. A history of direct or indirect contact with rats was identified in 19 patients (55.9%), supporting the zoonotic transmission route of Leptospira spp., particularly in urban settings with poor sanitation
The initial clinical manifestations included fever (94.1%), jaundice (82.4%), nausea and vomiting (73.5%), diarrhea (52.9%), muscle pain (50%), and shortness of breath (44.1%). Initial laboratory results in this study revealed anemia, leukocytosis, and thrombocytopenia. In addition, hepatic dysfunction was observed as one of the early manifestations of leptospirosis, characterized by elevated serum levels of AST, ALT, direct bilirubin, and indirect bilirubin.
Acute kidney injury was observed in 30 patients (88.2%), with mean initial blood urea level of 205.2 ± 117.9 mg/dL and mean initial creatinine level of 5.4±2.9 mg/dL. According to the AKIN criteria, 1 patient was classified as AKI stage 1, 5 patients as AKI stage 2, and 24 patients as AKI stage 3. Among the patients with AKI stage 3, 27 hemodialysis procedures were performed. The frequency of hemodialysis sessions during hospitalization was as follows: 1 session in 3 patients, 2 sessions in 6 patients, and 3 sessions in 14 patients. The average length of hospital stay was 11.2 ± 6.3 days, and 8 patients (23.5%) required treatment in the intensive care unit (ICU). The mortality rate was 11.8%, and all deaths occurred in patients with AKI stage 3
Acute kidney injury is one of the common clinical manifestations found in leptospirosis. In addition to adequate antibiotic therapy, hemodialysis is often required when accompanied by severe acute kidney injury.
