Abstract: | Acute kidney injury (AKI) can become complicated after paracentesis due to extrarenal fluid loss and inadequate blood flow to the kidneys. The objective of this study was to explore the incidence and clinical implications of postparacentesis AKI.A retrospective cohort of 137 liver cirrhosis patients (mean age: 61.3 ± 11.8 years, male: 100 73.0%], viral hepatitis: 93 67.9%]) who underwent paracentesis was analyzed. The incidence of AKI as defined by the international club of ascites (ICA) criteria, the risk factors, and its impact on early mortality were all assessed.Thirty two patients (23.4%) developed AKI after paracentesis. In multivariate analysis, the Model for end-stage liver disease (MELD)-Na score was an independent factor associated with AKI development (odds ratio OR], 1.14; 95% confidence interval CI], 1.07–1.23) after paracentesis. The incidence of early mortality was significantly higher for those with AKI than without AKI (71.9% 23/32 patients] vs 11.4% 12/105 patients], P < .001). AKI (hazard ratio HR], 7.56; 95% CI, 3.40–16.8) and MELD-Na score (HR, 1.08; 95% CI, 1.02–1.14) were independent factors associated with early mortality. In subgroup analysis, AKI after paracentesis was associated with significantly higher early mortality in both MELD-Na groups, that is, patients with a MELD-Na score >26 (87.5% vs 22.2%, P < .001) and those with a MELD-Na score ≤26 (56.3% vs 9.2%, P < .001).Postparacentesis AKI occurred frequently in cirrhotic patients. Furthermore, it was associated with early mortality. Baseline MELD-Na score was associated with AKI, indicating that careful attention is required for those with a higher MELD-Na score who are being considered for therapeutic paracentesis. |
