RESUMEN
Background & aims: Severe alcoholic hepatitis (SAH) is a grave condition, and the presence of acute kidney injury (AKI) further jeopardizes patient survival. However, the impact of AKI on survival in SAH has not been assessed from this region of Asia. Materials and methods: This study was conducted on consecutive alcohol-associated liver disease (ALD) patients hospitalized in Gastroenterology Department, SCB Medical College, Cuttack, India, between October 2016 and December 2018. On diagnosis of SAH (mDF score ≥32), demographic, clinical, and laboratory parameters were recorded, and survival was compared between patients with and without AKI (AKIN criteria). In addition, survival was compared among SAH patients defined by other criteria and prognostic models in the presence and absence of AKI. Results: 309 (70.71%) of ALD patients had SAH, and 201 (65%) of them had AKI. SAH patients with AKI had higher total leucocyte count, total bilirubin, serum creatinine, serum urea, INR, MELD (UNOS), MELD (Na+), CTP score, mDF score, Glasgow score, ABIC score, and increased prevalence of acute on chronic liver failure (ACLF) as per EASL-CLIF Consortium criteria (P < 0.001). Further, they had prolonged hospital stay, and increased death during hospitalization, at 28 days as well as 90 days (P < 0.001). Significant differences in survival were also seen in SAH (as per MELD, ABIC, and GAHS criteria) patients above the marked cut offs in respect to AKI. Conclusions: Over two-thirds of ALD patients had SAH, and about two-thirds had AKI. Patients with SAH and AKI had an increased prevalence of ACLF, longer hospital stay, and increased mortality during hospitalization at 28 days and 90 days. Lay summary: SAH is a critical condition, and the presence of AKI negatively affects their survival. Hence, early identification of SAH and AKI, as well as early initiation of treatment, is crucial for better survival. Our study from the coastal part of eastern India is the first to demonstrate the prevalence of SAH among patients with ALD along with the prevalence of AKI among SAH patients in this region. This knowledge will be helpful in managing these patients from this region of world.
RESUMEN
BACKGROUND: The occurrence of acute kidney injury (AKI) in acute-on-chronic liver failure (ACLF) negatively impacts the survival of patients. There are scant data on the impact of serum urea on outcomes in these patients. We performed this study to evaluate the relationship between admission serum urea and the survival in patients with ACLF and AKI. METHODS: A prospective study was conducted on patients with ACLF (as per Asian Pacific Association for the Study of the Liver criteria) and AKI (as per Acute Kidney Injury Network criteria) hospitalized in the gastroenterology ward between October 2016 and May 2018. Demographic, clinical and laboratory parameters were recorded, and outcomes were compared in patients with respect to the admission serum urea level. RESULTS: A total of 103 of 143 hospitalized patients with ACLF had AKI and were included as study subjects. The discrimination ability between survivors and the deceased was similar for serum urea levels (area under the receiver operating characteristic curve [AUROC] [95% confidence interval {CI}]: 28 days survival, 0.76 [0.67-0.85]; 90 days survival, 0.81 [0.72-0.91]) and serum creatinine levels (AUROC [95% CI]: 28 days survival, 0.75 [0.66-0.84]; 90 days survival: 0.77 [0.67-0.88]) in patients with ACLF and AKI. However, on multivariate analysis, admission serum urea (not serum creatinine) was an independent predictor of mortality in these patients both at 28 days (p = 0.001, adjusted hazard ratio [AHR]: 1.013 [1.005-1.021]) and 90 days (p = 0.001, AHR: 1.014 [1.006-1.022]). CONCLUSION: Over two-thirds of patients with ACLF had AKI. The discrimination ability between survivors and the deceased was similar for both serum urea and serum creatinine levels. However admission serum urea was found to be a better predictor of mortality than serum creatinine in patients with ACLF and AKI.
RESUMEN
BACKGROUND AND AIM: Acute kidney injury (AKI) is a common complication of chronic liver disease (CLD). We performed a prospective study to evaluate the risk factors and spectrum of AKI among decompensated cirrhosis (DC) patients and the impact of AKI on survival. METHODS: This study was conducted in consecutive DC patients hospitalized in SCB Medical College between December 2016 and October 2018. AKI was defined as per ICA criteria. Demographic, clinical, and laboratory parameters and outcomes were compared between patients with and without AKI. RESULTS: A total of 576 DC subjects were enrolled, 315 (54.69%) of whom had AKI; 34% (n = 106) had stage 1A, 28% (n = 90) stage 1B, 21% (n = 65) stage 2, and 17% (n = 54) stage 3 AKI. Alcohol was the predominant cause of CLD (66.7%). In 207 (65.7%) patients, diuretic/lactulose/nonsteroidal anti-inflammatory drugs use was noted, and infection was present in 190 (60.3%) patients. Compared to those without AKI, patients with AKI had higher leucocyte count, higher serum urea and creatinine, higher Child-Turcotte-Pugh, higher Model of End-Stage Liver Disease (MELD) scores (P < 0.001), longer hospital stay, and lower survival at 28 days and 90 days (P < 0.001). Besides, in patients with stages 1A to 3 AKI, there were differences in overall survival at 28 days (P < 0.001) and 90 days (P < 0.001). CONCLUSIONS: Over half of DC patients had AKI, and alcohol was the most common cause of cirrhosis in them. Use of AKI-precipitating medications was the most common cause of AKI, followed by bacterial infection. AKI patients had increased prevalence of acute-on-chronic liver failure and had prolonged hospitalization and lower survival both at 28 days and 90 days.
