CCL2 and acute kidney injury: Among patients with confirmed leptospirosis (n = 79), median serum (457.30 vs. 120.90, p = 0.0080) and urine (450.90 vs. 133.30, p = 0.0019) MCP-1 were also significantly higher in patients with AKI, whereas among leptospirosis-unconfirmed patients, the findings were not significant between the two groups in the serum (132.60 vs. 94.09, p = 0.6178) and urine (209.50 vs. 144.60, p = 0.9036) (Table 3).
