Leptospirosis is recognized as a globally re-emerging zoonosis. Interstitial nephritis is the principal feature of the disease. Leptospirosis-induced acute kidney injury typically is nonoliguric and includes hypokalemia. ⋯ The severe form (Weil's disease) manifests as diffuse alveolar hemorrhage, pulmonary edema, acute respiratory distress syndrome, or a combination of these features, accompanied by acute kidney injury and can be highly lethal. Antibiotic treatment is efficient in the early and late/severe phases. For critically ill leptospirosis patients, the following are recommended: daily hemodialysis, low daily net fluid intake (because of the risk for pulmonary hemorrhage), and lung-protective strategies (low tidal volumes and high positive end-expiratory pressures after recruitment maneuvers).
