Abstract
Multiple mechanisms may contribute to the occurrence of renal impairment (RI) in patients with spontaneous bacterial peritonitis (SBP). One such mechanism is systemic inflammatory response syndrome, which involves the release of pro-inflammatory cytokines (tumour necrosis factor [TNF]-α, interleukin [IL]-6 and vascular cell adhesion molecule [VCAM]-1). The goal of this research was to evaluate the role of IL-6, TNF-α and VCAM-1 as potential predictors of RI and mortality in cirrhotic patients with SBP. This study included 90 cirrhotic patients with SBP, divided into two equal groups: group A was patients without RI and group B was patients with RI. Based on mortality outcomes, the patients were further categorized into group 1 (recovery, n=70) and group 2 (death, n=20). TNF-α, IL-6 and VCAM-1 serum levels were measured using enzyme-linked immunosorbent assay. RI occurred in 50% (45/90) of the study population. Among the 90 patients, 10 (11.1%) had elevated IL-6 levels, 8 (8.9%) had elevated TNF-α levels and 6 (6.7%) had elevated VCAM-1 levels. There were no significant variations in cytokine levels between groups A and B. With an area under the curve of 0.5, the three cytokines showed comparable sensitivity and specificity as predictors of RI. The use of TNF-α, IL-6 and VCAM-1 as predictive markers for RI and mortality in SBP patients is not recommended, as these biomarkers demonstrated limited diagnostic value.
