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.

Salmonella typhimurium, a non-typhoidal salmonella, is an unusual cause of spontaneous bacterial peritonitis (SBP). It is usually reported in asymptomatic patients with normal or high ascitic fluid protein levels with underlying immunosuppression, as high opsonic activity in the ascitic fluid of these patients protects them from the usual organisms causing spontaneous bacterial peritonitis, unless they are exposed to a particularly virulent organism like salmonella. We report a case of culture-proven non-typhoidal salmonella in a patient with decompensated cirrhosis, with low protein and without any underlying immunosuppression, and no other source to explain its origin.
ABSTRACT
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.
