Secondary bacterial peritonitis in cirrhosis: A retrospective study of clinical and analytical characteristics, diagnosis and management

BACKGROUND & AIMS Secondary bacterial peritonitis in cirrhotic patients is an uncommon entity that has been little reported. Our aim is to analyse the frequency, clinical characteristics, treatment and prognosis of patients with secondary peritonitis in comparison to those of patients with spontaneous bacterial peritonitis (SBP). METHODS Retrospective analysis of 24 cirrhotic patients with secondary peritonitis compared with 106 SBP episodes. RESULTS Secondary peritonitis represented 4.5% of all peritonitis in cirrhotic patients. Patients with secondary peritonitis showed a significantly more severe local inflammatory response than patients with SBP. Considering diagnosis of secondary peritonitis, the sensitivity of Runyons criteria was 66.6% and specificity 89.7%, Runyons criteria and/or polymicrobial ascitic fluid culture were present in 95.6%, and abdominal computed tomography was diagnostic in 85% of patients in whom diagnosis was confirmed by surgery or autopsy. Mortality during hospitalization was higher in patients with secondary peritonitis than in those with SBP (16/24, 66.6% vs. 28/106, 26.4%) (p<0.001). There was a trend to lower mortality in secondary peritonitis patients who underwent surgery (7/13, 53.8%) than in those who received medical treatment only (9/11, 81.8%) (p=0.21). Considering surgically treated patients, the time between diagnostic paracentesis and surgery was shorter in survivors than in non-survivors (3.2+/-2.4 vs. 7.2+/-6.1 days, p=0.31). CONCLUSIONS Secondary peritonitis is an infrequent complication in cirrhotic patients but mortality is high. A low threshold of suspicion on the basis of Runyons criteria and microbiological data, together with an aggressive approach that includes prompt abdominal computed tomography and early surgical evaluation, could improve prognosis in these patients.

Role of Albumin Treatment in Patients With Spontaneous Bacterial Peritonitis

BACKGROUND & AIMS Intravenous administration of albumin decreases the incidence of renal failure and mortality among patients with spontaneous bacterial peritonitis (SBP). However, it is unclear whether it should be given to all patients with SBP; we evaluated its efficacy. METHODS We analyzed data from all episodes of SBP (n = 216) during a 7-year period that occurred in a nonselected series of 167 patients with cirrhosis. Low-risk episodes (urea <11 mmol/L and bilirubin <68 μmol/L) were not treated with albumin, whereas high-risk episodes (urea >11 mmol/L and/or bilirubin >68 μmol/L) were or were not given albumin at the discretion of the attending physician. RESULTS Sixty-four episodes of SBP (29.6%) were low risk and not treated with albumin, whereas 152 (70.4%) were high risk; 73 of these (48%) were treated with albumin and 79 (52%) were not. Renal failure before SBP resolution was less frequent after low-risk episodes than high-risk episodes (4.7% versus 25.6%; P = .001), in-hospital mortality was lower (3.1% versus 38.2%; P < .001), and the 3-month probability of survival was higher (93% versus 53%; P < .001). In an analysis of only the high-risk group, patients who received albumin had lower in-hospital mortality than those not treated with albumin (28.8% versus 46.8%; P = .02) and a greater 3-month probability of survival (62% versus 45%; P = .01). CONCLUSIONS Albumin therapy increases survival of patients who have high-risk episodes of SBP, although it does not seem to be necessary for patients with low risk of death.

Impact of anticoagulation on upper-gastrointestinal bleeding in cirrhosis. A retrospective multicenter study.

Recent studies have shown that liver cirrhosis (LC) behaves as an acquired hypercoagulable state with increased thrombotic risk. This is why anticoagulation therapy (AT) is now frequently used in these patients. Variceal bleeding is a severe complication of LC. It is unknown whether AT may impact the outcome of bleeding in these patients. Fifty‐two patients on AT with upper gastrointestinal bleeding (UGIB) were evaluated. Portal vein thrombosis (PVT) and different cardiovascular disorders (CVDs) were the indication for AT in 14 and 38 patients, respectively. Overall, 104 patients with LC and UGIB not under AT matched for severity of LC, age, sex, source of bleeding, and Sequential Organ Failure Assessment (SOFA) score served as controls. UGIB was attributed to portal hypertension (PH) in 99 (63%) patients and peptic/vascular lesions in 57 (37%). Twenty‐six (17%) patients experienced 5‐day failure; SOFA, source of UGIB, and PVT, but not AT, were independent predictors of 5‐day failure. In addition, independent predictors of 6‐week mortality, which was observed in 26 (11%) patients, were SOFA, Charlson Comorbidity index, and use of AT for a CVD. There were no differences between patients with/without AT in needs for rescue therapies, intensive care unit admission, transfusions, and hospital stay. Conclusions: Factors that impact the outcome of UGIB in patients under AT are degree of multiorgan failure and comorbidity, but not AT itself. (Hepatology 2015;62:575–583

Predictive model of mortality in patients with spontaneous bacterial peritonitis

Hospital mortality in patients with spontaneous bacterial peritonitis (SBP) is high despite albumin treatment, particularly in those with worse liver and/or renal function.

Survival of patients with cirrhosis and acute peptic ulcer bleeding compared with variceal bleeding using current first-line therapies

The presence of cirrhosis increases the mortality of patients with peptic ulcer bleeding (PUB). Both acute variceal bleeding (AVB) and PUB are associated with substantial mortality in cirrhosis. This multicenter cohort study was performed to assess whether the mortality of patients with cirrhosis with PUB is different from that of those with AVB. Patients with cirrhosis and acute gastrointestinal bleeding were consecutively included and treated with somatostatin and proton pump inhibitor infusion from admission and with antibiotic prophylaxis. Emergency endoscopy with endoscopic therapy was performed within the first 6 hours. 646 patients with AVB and 144 with PUB were included. There were baseline differences between groups, such as use of gastroerosive drugs or β‐blockers. Child‐Pugh and Model for End‐Stage Liver Disease MELD scores were similar. Further bleeding was more frequent in the AVB group than those in the PUB group (18% vs. 10%; odds ratio [OR] = 0.50; 95% confidence interval [CI] = 0.29‐0.88). However, mortality risk at 45 days was similar in both groups (19% in the AVB group vs. 17% in the PUB group; OR = 0.85; 95% CI = 0.55‐1.33; P = 0.48). Different parameters, such as Child‐Pugh score, acute kidney injury, acute on chronic liver failure, or presence of shock or bacterial infection, but not the cause of bleeding, were related to the risk of death. Only 2% of the PUB group versus 3% of the AVB group died with uncontrolled bleeding (P = 0.39), whereas the majority of patients in either group died from liver failure or attributed to other comorbidities. Conclusion: Using current first‐line therapy, patients with cirrhosis and acute peptic ulcer bleeding have a similar survival than those with variceal bleeding. The risk of further bleeding is higher in patients with variceal hemorrhage. However, few patients in both groups died from uncontrolled bleeding, rather the cause of death was usually related to liver failure or comorbidities. (Hepatology 2018;67:1458‐1471).

Usefulness of indirect noninvasive methods in predicting progression to cirrhosis in chronic hepatitis C.

Background and aims The ability of noninvasive methods to predict the development of cirrhosis has not been established. We evaluated the ability of three noninvasive methods [the Forns index, the aspartate aminotransferase-to-platelet ratio index (APRI), and the Non-Invasive Hepatitis-C-related Cirrhosis Early Detection (NIHCED) score] to determine the risk of developing cirrhosis in chronic hepatitis C. Methods Consecutive patients with chronic hepatitis C who had undergone liver biopsy between 1998 and 2004 were eligible. We used the three methods to evaluate patients at baseline and at follow-up (4–10 years later). When these methods yielded discordant or indeterminate results, a second liver biopsy was performed. Logistic regression models were fitted for each method to predict whether cirrhosis would appear and to predict long-term mortality from cirrhosis. Results We included 289 patients in our study. The mean scores at baseline and at follow-up, respectively, were as follows: Forns, 5.47±1.95 and 6.56±2.02; APRI, 1.1±2.33 and 1.4±1.53; and NIHCED, 7.79±11.45 and 15.48±15.28. The area under the receiver operating characteristic curve for predicting cirrhosis was 0.83 for Forns, 0.79 for APRI, and 0.76 for NIHCED. The sensitivity and specificity for predicting cirrhosis, respectively, were 75 and 71% for Forns (cutoff 4.7), 86 and 42% for APRI (cutoff 0.48), and 41 and 82% for NIHCED (cutoff 0). The area under the receiver operating characteristic curve for predicting mortality was 0.86 for Forns, 0.79 for APRI, and 0.84 for NIHCED. Conclusion Indirect noninvasive markers could help identify patients with chronic hepatitis C at risk of progression to cirrhosis.

Factors related to survival in hepatocellular carcinoma in the geographic area of Sabadell (Catalonia, Spain)

BACKGROUND hepatocellular carcinoma (HCC) is a very frequent tumor. Screening for the disease is effective, but the prognostic factors are difficult to evaluate. OBJECTIVES 1. To determine epidemiological data and the clinical course of HCC in our setting. 2. To compare patient survival according to whether screening is performed or not. 3. To evaluate survival prognostic factors. PATIENTS AND METHODS data on the epidemiology and clinical course of patients diagnosed with HCC were collected on a prospective basis (January 2004-December 2006). Two groups were considered according to whether screening had been performed (group A) or not (group B). RESULTS a total of 110 patients were diagnosed with HCC (70% males). The most common etiology of cirrhosis was hepatitis C (56.1%), and 69% presented mild liver failure (Child-Pugh grade A). The median follow-up was 1.8 years. Fifty-one percent had been subjected to screening. The diagnosis of HCC was established by imaging techniques in 48.2% of the cases, and by histological criteria in 51.8%. The median tumor size was 23 mm in group A and 28 mm in group B (p = 0.005). Treatment with curative intent was provided in 72% of the cases in group A and in 48% in group B (p = 0.011). The median overall survival was 1.99 years -2.67 years in group A and 1.75 years in group B (p = 0.05). The multivariate analysis of overall survival showed the type of treatment (OR = 2.82 95%CI: 1.3-6.12, p = 0.009) and liver function (OR = 1.71 95%CI: 1.1-2.68, p = 0.020) to be independent predictors of survival. CONCLUSIONS screening allows the diagnosis of smaller lesions and a higher percentage of curative treatments. The degree of liver function and the provision of curative treatment are independent predictors of survival.

Larga supervivencia tras resección de metástasis craneal de hepatocarcinoma. Descripción de un caso y revisión de la literatura

The life expectancy of patients with hepatocellular carcinoma (HCC) has increased in the last few years due to recent treatment advances. However, extrahepatic metastases from tumors, previously described only occasionally, are becoming more frequent in clinical practice. The choice between an active or passive approach to these metastatic lesions can sometimes present clinicians with a difficult dilemma. We discuss the case of a male patient with multifocal HCC and cranial metastasis from a primary liver tumor and who, after surgery and radiotherapy over the metastatic lesion, has survived for more than 3 years.

Inter and intra-observer concordance for the diagnosis of portal hypertension gastropathy

INTRODUCTION At present there is no fully accepted endoscopic classification for the assessment of the severity of portal hypertensive gastropathy (PHG). Few studies have evaluated inter and intra-observer concordance or the degree of concordance between different endoscopic classifications. OBJECTIVES To evaluate inter and intra-observer agreement for the presence of portal hypertensive gastropathy and enteropathy using different endoscopic classifications. METHODS Patients with liver cirrhosis were included into the study. Enteroscopy was performed under sedation. The location of lesions and their severity was recorded. Images were videotaped and subsequently evaluated independently by three different endoscopists, one of whom was the initial endoscopist. The agreement between observations was assessed using the kappa index. RESULTS Seventy-four patients (mean age 63.2 years, 53 males and 21 females) were included. The agreement between the three endoscopists regarding the presence or absence of PHG using the Tanoue and McCormack classifications was very low (kappa scores = 0.16 and 0.27, respectively). CONCLUSIONS The current classifications of portal hypertensive gastropathy have a very low degree of intra and inter-observer agreement for the diagnosis and assessment of gastropathy severity.
