Renal involvement in sepsis: A prospective single-center study of 136 cases

Abstract

Acute kidney injury (AKI) is an independent risk factor for mortality in sepsis syndrome. Few Indian studies have focused on describing the epidemiology of sepsis with AKI. Adult patients with sepsis-induced AKI were evaluated for the clinical characteristics and outcome and to correlate various parameters associated with sepsis to the outcome of patients. This prospective study included 136 patients with sepsis-induced AKI between 2007 and 2009. All patients required renal replacement therapy. Males comprised 44% of the patients while 56% were females; their mean age was 38.6 years. When we compared the survivor and non-survivor groups, it was found that mortality was associated with delayed presentation (6.8 vs 9.4 days), presence of hypotension (132/80 vs 112/70 mmHg), oliguria (300 vs 130 mL), anemia (8 vs 9.3 gm/dL), prolonged prothrombin time (15 vs 29 s) and activated partial thrombin time (38 vs 46 s), creatinine (7.8 vs 6.4 mg/dL), blood urea (161 vs 135 mg/dL), higher D-dimer (1603 vs 2185), short hospital stay (27.9 vs 8.3 days), number of hemodialysis sessions (11.9 vs 6 times), need for vasopressors (14% vs 52%) and ventilator (7.2% vs 75%) and higher Sequential Organ Failure Assessment (SOFA) score (6.7 vs 11.4) (P 11 and multi-organ dysfunction are the risk factors for mortality.
