In the patients without confirmed leptospirosis, serum KIM-1 (44.94 vs. 13.71, p = 0.0233) showed a significant elevation among the six patients with AKI while urine KIM-1 (156.00 vs. 76.28, p = 0.4956) was not significantly elevated in this group (Table 3). Here, HAVCR1 is linked to acute kidney injury.
