ABSTRACT
BACKGROUND: This study aims to determine the predictive power of baseline C-reactive protein (CRP) value in cirrhotic patients with ascites, without overt infection, that might lead to spontaneous bacterial peritonitis (SBP)/ cellullitis. METHODS: 152 consecutive cirrhotic patients with ascites, without overt infection were included in the study, after measuring the baseline CRP value. All patients were followed up for a duration of one year, or till development of SBP/cellulitis. RESULTS: Baseline CRP was elevated in 76.8% of the patients. Development of infection was observed in 78 (51.3%) patients. SBP was diagnosed in 54 patients, cellulitis was documented in 15 patients. 9 patients had simultaneous SBP and cellulitis Baseline CRP was 10.2 ± 6.34 mg/dL in the group who developed infection, it was 4.81 ± 4.41 mg/dL in the group who did not develop infection (p = 0.002). Baseline CRP > 9.5 mg/dL, serum albumin < 2.8 g/dL and a previous history of infection were independent predictors of developing SBP/cellulitis. CONCLUSIONS: Along with low serum albumin and previous history of infection, CRP can be used as a predictive tool for early detection of infection, thus enabling to reduce the morbidity and mortality.

BACKGROUND: This study aimed to assess whether QT interval prolongation is an independent risk factor for development of hepatorenal syndrome (HRS) in cirrhotic patients with acute variceal bleeding. METHODS: 78 consecutive cirrhotic patients with acute variceal bleeding were included in the study. All patients were evaluated before bleeding (T0), during bleeding (T1) and 6 weeks later (T2). RESULTS: HRS developed in 14 (17.9%) patients. QT corrected by heart rate (QTc) prolonged at T1, returning towards baseline at T2 (mean ± SD; from 424.0 ± 10.2 to 461.2 ± 17.6 to 426.1 ± 8.8ms, P < 0.001). At T1, patients who developed HRS had longer QTc (P = 0.017) and lower serum sodium (P = 0.039). QTc and serum sodium independently predicted HRS; the best cut-off values were QTc > 468 ms and sodium < 120 mEq/L. Patients on beta-blocker were found to have significant risk for developing HRS (p = 0.040). Based on these three factors, the risk for HRS was nil for patients without risk factors; 6.1%, 11.1%, and 83.3% for those with one, two or three risk factors, respectively (p < 0.001). CONCLUSIONS: Acute variceal bleeding causes further prolongation of QTc in cirrhosis. The combination of beta-blocker, QTc interval and serum sodium can aid in early detection of patients at increased risk of developing bleed-precipitated HRS, thus improving their outcome.
