An Emulated Clinical Trial of Deprescribing Proton Pump Inhibitors in Patients With Cirrhosis.

INTRODUCTION: Proton pump inhibitors (PPI) are overused and carry harms in cirrhosis. Deprescribing is advocated but has not been trialed. METHODS AND FINDINGS: We emulated a clinical trial using Medicare data. All patients were receiving chronic PPI therapy before a compensated cirrhosis diagnosis. We compared the risk death/decompensation over 3 years between continuous users and deprescribers. We find that PPI deprescription is associated with less ascites and that cumulative PPI use is associated with more ascites and encephalopathy. Ultimately, 71% of deprescribers restart PPIs. DISCUSSION: PPI deprescribing has benefits but requires ongoing support and alternative therapies for gastrointestinal symptoms.

Development of a Risk Stratification Model for Pre-liver-Transplant Screening Colonoscopy.

BACKGROUND AND AIMS: Colonoscopies are routinely obtained before liver transplantation, although their utility is a highly debated topic in the literature. We aimed to determine the risk factors in patients with decompensated cirrhosis (DC) for post-colonoscopy complications (PCC). MATERIALS AND METHODS: We performed a single-center retrospective study of patients with DC undergoing colonoscopy as part of their pre-liver-transplant evaluation. The primary composite outcome was defined as a complication occurring within 30 days of the colonoscopy. Complications included acute renal failure, new or worsening ascites or hepatic encephalopathy, gastrointestinal bleeding, or any cardiopulmonary or infectious complication. Logistic regression analysis was utilized to derive a risk score in predicting the primary composite outcome. RESULTS: The strongest predictors of post-colonoscopy complication were MELD-Na ≥21 [aOR 4.0026 ( P =0.0050)] and history of any infection in the 30 days before colonoscopy [aOR 8.4345 ( P =0.0093)]. The area under the receiver operating characteristic curve of the final model was 0.78. The predicted risk of any complication at the lowest quartile was 16.2% to 39.4%, and the observed risk was 30.6% (95% CI: 15.5-45.6%), while the predicted risk at the highest quartile was 71.9% to 97.1%, and the observed risk was 81.3% (95% CI: 67.7-95%). CONCLUSION: In this cohort of patients with DC undergoing colonoscopy for pre-liver-transplant evaluation, a history of ascites, spontaneous bacterial peritonitis, and MELD-Na were found to be predictive of PCC. This risk score may help to predict PCC in patients with DC undergoing a pre-transplant colonoscopy. External validation is recommended.

Prognostic Factors in Alcohol-associated Liver Disease Patients Presenting With First Evidence of Ascites.

GOALS: To identify factors associated with transplantation and death in alcohol-associated liver disease (ALD) patients presenting with first evidence of ascites. BACKGROUND: Ascites development is a poor prognostic sign for patients with cirrhosis. Among ALD patients, the baseline factors at time of ascites development that are associated with eventual transplantation or death are currently unknown. STUDY: Adult patients with ascites in the "Evaluating Alcohol Use in Alcohol-related Liver Disease Prospective Cohort Study" (NCT03267069 clinicaltrials.gov) were identified from 2016 to 2020. Demographic, clinical, and laboratory factors at initial ascites presentation were identified as potential predictors of transplant and death as competing risks. RESULTS: A total of 96 patients were identified. Median (interquartile range) follow-up time was 2.00 years (0.87 to 3.85). By last follow-up, 34/96 patients had been transplanted (35.4%) and 11/96 had died (11.4%). Prognostic factors for transplant included age per decade [hazard ratio (HR): 0.52 (95% CI, 0.33 to 0.83)], employed status [HR: 0.35 (95% CI, 0.14 to 0.90)], and sodium [HR: 0.94 (95% CI, 0.90 to 0.99)], whereas prognostic factors for death were body mass index [HR: 1.11 (95% CI, 1.00 to 1.22)], Charlson index [HR: 2.14 [95% CI, 1.13 to 4.08]), Maddrey Discriminant Function >32 (HR: 5.88 (95% CI, 1.18, 29.39)], aspartate aminotransferase [HR: 0.99 (95% CI, 0.98 to 0.997)], and a prior 12-month abstinence period [HR: 5.53 (95% CI, 1.10 to 27.83)], adjusted for age, sex, and ALD subcategory. CONCLUSIONS: Several factors at initial ascites presentation are associated with increased risk of transplantation or death and validation in larger cohorts will allow for improved risk stratification for ALD patients.

Prophylactic Intra-abdominal Drainage is Associated With Lower Postoperative Complications in Patients With Crohn's Disease: A Randomized Controlled Trial.

BACKGROUND: Prophylactic intraoperative drains have been shown not superior for patients underwent intestinal surgery. However, for patients with Crohn's disease (CD), this needs further exploration. METHODS: In this pilot study, CD patients were randomly assigned to drain (n = 50) and no-drain (n = 50) groups. The primary endpoint was the rate of postoperative prolonged ileus (PPOI). The secondary endpoints were postoperative abdominal ascites, postoperative systemic inflammatory response syndrome (SIRS) and C-reactive protein (CRP) levels. RESULTS: The incidences of PPOI and postoperative abdominal ascites were significantly lower in the drain group (12% vs 44%; 0% vs 24%, both P < .05). Postoperative SIRS incidence and CRP levels were significantly increased in the no-drain group [36% vs 10%; 54.9 vs 34.3 mg/L, both P < .05]. In multivariate analysis, prophylactic drainage was the independent protective factor for PPOI and postoperative LOS. CONCLUSIONS: Prophylactic drainage may be associated with improved clinical outcomes in CD patients.

[Prognostic nutritional index application value for acute-on-chronic liver failure co-infection].

Objective: To explore the predictive value of the prognostic nutritional index (PNI) in concurrently infected patients with acute-on-chronic liver failure (ACLF). Methods: 220 cases with ACLF diagnosed and treated at the First Affiliated Hospital of Xi'an Jiaotong University from January 2011 to December 2016 were selected. Patients were divided into an infection and non-infection group according to whether they had co-infections during the course of the disease. Clinical data differences were compared between the two groups of patients. Binary logistic regression analysis was used to screen out influencing factors related to co-infection. The receiver operating characteristic curve was used to evaluate the predictive value of PNI for ACLF co-infection. The measurement data between groups were compared using the independent sample t-test and the Mann-Whitney U rank sum test. The enumeration data were analyzed using the Fisher exact probability test or the Pearson χ(2) test. The Pearson method was performed for correlation analysis. The independent risk factors for liver failure associated with co-infection were analyzed by multivariate logistic analysis. Results: There were statistically significant differences in ascites, hepatorenal syndrome, PNI score, and albumin between the infection and the non-infection group (P < 0.05). Among the 220 ACLF cases, 158 (71.82%) were infected with the hepatitis B virus (HBV). The incidence rate of infection during hospitalization was 69.09% (152/220). The common sites of infection were intraabdominal (57.07%) and pulmonary infection (29.29%). Pearson correlation analysis showed that PNI and MELD-Na were negatively correlated (r = -0.150, P < 0.05). Multivariate logistic analysis results showed that low PNI score (OR=0.916, 95%CI: 0.865~0.970), ascites (OR=4.243, 95%CI: 2.237~8.047), and hepatorenal syndrome (OR=4.082, 95%CI : 1.106~15.067) were risk factors for ACLF co-infection (P < 0.05). The ROC results showed that the PNI curve area (0.648) was higher than the MELD-Na score curve area (0.610, P < 0.05). The effectiveness of predicting infection risk when PNI was combined with ascites and hepatorenal syndrome complications was raised. Patients with co-infections had a good predictive effect when PNI ≤ 40.625. The sensitivity and specificity were 84.2% and 41.2%, respectively. Conclusion: Low PNI score and ACLF co-infection have a close correlation. Therefore, PNI has a certain appraisal value for ACLF co-infection.

Alternative forms of portal vein revascularization in liver transplant recipients with complex portal vein thrombosis.

BACKGROUND & AIMS: Complex portal vein thrombosis (PVT) is a challenge in liver transplantation (LT). Extra-anatomical approaches to portal revascularization, including renoportal (RPA), left gastric vein (LGA), pericholedochal vein (PCA), and cavoportal (CPA) anastomoses, have been described in case reports and series. The RP4LT Collaborative was created to record cases of alternative portal revascularization performed for complex PVT. METHODS: An international, observational web registry was launched in 2020. Cases of complex PVT undergoing first LT performed with RPA, LGA, PCA, or CPA were recorded and updated through 12/2021. RESULTS: A total of 140 cases were available for analysis: 74 RPA, 18 LGA, 20 PCA, and 28 CPA. Transplants were primarily performed with whole livers (98%) in recipients with median (IQR) age 58 (49-63) years, model for end-stage liver disease score 17 (14-24), and cold ischemia 431 (360-505) minutes. Post-operatively, 49% of recipients developed acute kidney injury, 16% diuretic-responsive ascites, 9% refractory ascites (29% with CPA, p <0.001), and 10% variceal hemorrhage (25% with CPA, p = 0.002). After a median follow-up of 22 (4-67) months, patient and graft 1-/3-/5-year survival rates were 71/67/61% and 69/63/57%, respectively. On multivariate Cox proportional hazards analysis, the only factor significantly and independently associated with all-cause graft loss was non-physiological portal vein reconstruction in which all graft portal inflow arose from recipient systemic circulation (hazard ratio 6.639, 95% CI 2.159-20.422, p = 0.001). CONCLUSIONS: Alternative forms of portal vein anastomosis achieving physiological portal inflow (i.e., at least some recipient splanchnic blood flow reaching transplant graft) offer acceptable post-transplant results in LT candidates with complex PVT. On the contrary, non-physiological portal vein anastomoses fail to resolve portal hypertension and should not be performed. IMPACT AND IMPLICATIONS: Complex portal vein thrombosis (PVT) is a challenge in liver transplantation. Results of this international, multicenter analysis may be used to guide clinical decisions in transplant candidates with complex PVT. Extra-anatomical portal vein anastomoses that allow for at least some recipient splanchnic blood flow to the transplant allograft offer acceptable results. On the other hand, anastomoses that deliver only systemic blood flow to the allograft fail to resolve portal hypertension and should not be performed.

Minimally Invasive Versus Open Liver Resections for Hepatocellular Carcinoma in Patients With Metabolic Syndrome.

OBJECTIVE: To compare minimally invasive (MILR) and open liver resections (OLRs) for hepatocellular carcinoma (HCC) in patients with metabolic syndrome (MS). BACKGROUND: Liver resections for HCC on MS are associated with high perioperative morbidity and mortality. No data on the minimally invasive approach in this setting exist. MATERIAL AND METHODS: A multicenter study involving 24 institutions was conducted. Propensity scores were calculated, and inverse probability weighting was used to weight comparisons. Short-term and long-term outcomes were investigated. RESULTS: A total of 996 patients were included: 580 in OLR and 416 in MILR. After weighing, groups were well matched. Blood loss was similar between groups (OLR 275.9±3.1 vs MILR 226±4.0, P =0.146). There were no significant differences in 90-day morbidity (38.9% vs 31.9% OLRs and MILRs, P =0.08) and mortality (2.4% vs 2.2% OLRs and MILRs, P =0.84). MILRs were associated with lower rates of major complications (9.3% vs 15.3%, P =0.015), posthepatectomy liver failure (0.6% vs 4.3%, P =0.008), and bile leaks (2.2% vs 6.4%, P =0.003); ascites was significantly lower at postoperative day 1 (2.7% vs 8.1%, P =0.002) and day 3 (3.1% vs 11.4%, P <0.001); hospital stay was significantly shorter (5.8±1.9 vs 7.5±1.7, P <0.001). There was no significant difference in overall survival and disease-free survival. CONCLUSIONS: MILR for HCC on MS is associated with equivalent perioperative and oncological outcomes to OLRs. Fewer major complications, posthepatectomy liver failures, ascites, and bile leaks can be obtained, with a shorter hospital stay. The combination of lower short-term severe morbidity and equivalent oncologic outcomes favor MILR for MS when feasible.

Correction and Prevention of Hyponatremia in Patients With Cirrhosis and Ascites: Post Hoc Analysis of the ANSWER Study Database.

INTRODUCTION: We assessed the impact of long-term albumin administration to hyponatremic patients with ascites enrolled in the ANSWER trial. METHODS: The normalization rate of baseline hyponatremia and the 18-month incidence rate of at least moderate hyponatremia were evaluated. RESULTS: The hyponatremia normalization rate was higher with albumin than with standard medical treatment (45% vs 28%, P = 0.042 at 1 month). Long-term albumin ensured a lower incidence of at least moderate hyponatremia than standard medical treatment (incidence rate ratio: 0.245 [CI 0.167-0.359], P < 0.001). DISCUSSION: Long-term albumin administration improves hyponatremia and reduces episodes of at least moderate hyponatremia in outpatients with cirrhosis and ascites.

Carvedilol as the new non-selective beta-blocker of choice in patients with cirrhosis and portal hypertension.

Portal hypertension (PH) is the most common complication ofcirrhosis and represents the main driver of hepatic decompensation. The overarching goal of PH treatments in patients with compensated cirrhosis is to reduce the risk of hepatic decompensation (i.e development of ascites, variceal bleeding and/or hepatic encephalopathy). In decompensated patients, PH-directed therapies aim at avoiding further decompensation (i.e. recurrent/refractory ascites, variceal rebleeding, recurrent encephalopathy, spontaneous bacterial peritonitis or hepatorenal syndrome) and at improving survival. Carvedilol is a non-selective beta-blocker (NSBB) acting on hyperdynamic circulation/splanchnic vasodilation and on intrahepatic resistance. It has shown superior efficacy than traditional NSBBs in lowering PH in patients with cirrhosis and may be, therefore, the NSBB of choice for the treatment of clinically significant portal hypertension. In primary prophylaxis of variceal bleeding, carvedilol has been demonstrated to be more effective than endoscopic variceal ligation (EVL). In patients with compensated cirrhosis carvedilol achieves higher rate of hemodynamic response than propranolol, resulting in a decreased risk of hepatic decompensation. In secondary prophylaxis, the combination of EVL with carvedilol may prevent rebleeding and non-bleeding further decompensation better than that with propranolol. In patients with ascites and gastroesophageal varices, carvedilol is safe and may improve survival, as long as no impairment of the systemic hemodynamic or renal dysfunction occurs, with maintained arterial blood pressure as suitable safety surrogate. The target dose of carvedilol to treat PH should be 12.5 mg/day. This review summarizes the evidence behind Baveno-VII recommendations on the use of carvedilol in patients with cirrhosis.

Clinical outcomes of transjugular intrahepatic portosystemic shunt with PTFE-covered stents after liver transplantation and technical results in split and whole liver graft recipients.

OBJECTIVES: To assess the outcomes of transjugular intrahepatic portosystemic shunt (TIPS) creation using PTFE-covered stents in liver transplant (LT) recipients and to analyze the technical result of TIPS creation in split grafts (SG) compared with whole liver grafts (WG). METHODS AND MATERIALS: Single-center, retrospective study, analyzing LT patients who underwent TIPS using PTFE-covered stents. Clinical and technical variables were analyzed. RESULTS: Between 2005 and 2021, TIPS was created using PTFE-covered stents in 48 LT patients at a median of 43 months (range, 0.5-192) after LT. TIPS indications were refractory ascites (RA) in 33 patients (69%), variceal bleeding (VB) in 9 patients (19%), others in 6 (12%). Ten patients (21%) received a SG. Technical success rate was 100% in both groups: in two WG recipients, (5%) a second attempt was required. An unconventional approach (combined transhepatic or transplenic access) was needed in 2 WG (5%) and 2 SG recipients (20%). Two procedure-related death occurred in the WG group. After a median follow-up of 22 months (range, 0,1-144), 16 patients (48%) in the RA group did not require post-TIPS paracentesis, in the VB group rebleeding occurred in 3 patients (33%). Fifteen patients (31%) underwent TIPS revision. Overt hepatic encephalopathy occurred in 14 patients (29%). Patient survival at 6 months, 1 year, and 3 years was 77%, 66%, and 43%, respectively. CONCLUSIONS: The feasibility and safety of TIPS creation in SG are comparable to that of WG. TIPS creation using PTFE-covered stents represents a viable option to treat portal hypertensive complications in LT recipients. KEY POINTS: • TIPS creation using PTFE-covered stents represents a viable option to treat complications of PH in LT recipients. • TIPS creation in LT SG recipients appears to be safe and feasible as in WG. • Results from this study may help to refine the management of LT patients with recurrent portal hypertensive complications encouraging physicians to consider TIPS creation as a treatment option in both SG and WG recipients.

Trends in Mortality and Health Care Burden of Cirrhotic Decompensation in Hospitalized Patients: A Nationwide Analysis.

INTRODUCTION: Mortality caused by cirrhosis is now the 14th most common cause of death worldwide and 12th most common in the United States. We studied trends in inpatient mortality and hospitalization charges associated with cirrhotic decompensation from esophageal variceal bleeding, ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, and hepatorenal syndrome from 2007 to 2017. MATERIALS AND METHODS: Using the National Inpatient Sample databases, we first isolated patients 18 years or older with the diagnosis of cirrhosis using International Classification of Diseases, Ninth Revision (ICD-9) or International Classification of Diseases, Tenth Revision (ICD-10) codes. We then identified patients with the admission diagnosis of esophageal variceal bleeding, ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, and hepatorenal syndrome. Time-series regression was used to determine whether a trend occurred over the study period. We also evaluated for patient-related demographic changes over the study period. RESULTS: A total of 259,897 cirrhotic patients with the studied decompensations were captured. During the study period, time-series regression confirmed downtrends in mortality rates and length of stay for all types of decompensations. Conversely, we found increases in hospitalization charges for all types of decompensations. Patient age increased over the study period. Patients were also more likely to be White and pay with. CONCLUSION: From 2007 to 2017, inpatient mortality rates and lengths of stay decreased for cirrhotic decompensations for all causes of decompensation. Total charges, conversely, increased for all causes.

Development and validation of a nomogram to predict recompensation in HBV-related cirrhosis with ascites as the single first decompensating event.

BACKGROUND AND OBJECTIVE: Little is known about the influencing factors for recompensation in HBV-related cirrhosis patients with ascites as the single first decompensating event and it's necessary to build a prediction model for these patients. METHODS: Hepatitis B virus-related cirrhosis patients with ascites hospitalized for the first decompensation were included and they were divided into the training cohort (2010.03-2020.03) and the validation cohort (2020.04-2022.04). All patients received antiviral therapy within 3 months before admission or immediately after admission. Recompensation is defined as the patient's ascites disappeared without diuretics, which were maintained for more than 1 year and no other decompensated complications, hepatocellular carcinoma, or liver transplantation occurred. The nomogram was developed from a training cohort of 279 patients and validated in another cohort of 72 patients. RESULTS: Totally, 42.7% of the decompensated patients achieved recompensation. According to the results of logistic regression and competing risk analysis, six independent factors associated with recompensation were found and these factors comprised the nomogram: age, alanine aminotransferase (ALT), albumin (ALB), serum sodium (Na), alpha-fetoprotein (AFP), and maintained virological response (MVR). Through external validation, the area under the receiver operating characteristic curve (AUC) of the nomogram was 0.848 (95% CI: 0.761, 0.936), which was significantly better than CTP, MELD, MELDNa, MELD 3.0, and ALBI grade. CONCLUSIONS: Age, ALT, ALB, Na, AFP, and MVR are closely related to the recompensation. The nomogram developed based on these items can accurately predict the possibility of recompensation in hepatitis B cirrhosis patients with ascites as the single first decompensating event.

Systematically analysis of decompensated cirrhotic patients with spontaneous bacterial peritonitis to identify diagnostic and prognostic indexes.

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is a common complication in patients with cirrhosis. The diagnosis of SBP is still mostly based on ascites cultures and absolute ascites polymorphonuclear (PMN) cell count, which restricts the widely application in clinical settings. This study aimed to identify reliable and easy-to-use biomarkers for both diagnosis and prognosis of cirrhotic patients with SBP. METHODS: We conducted a retrospective study including 413 cirrhotic patients from March 2013 to July 2022 in the First Affiliated Hospital of Guangxi Medical University. Patients' clinical characteristics and laboratory indices were collected and analyzed. Two machine learning methods (Xgboost and LASSO algorithms) and a logistic regression analysis were adopted to screen and validate the indices associated with the risk of SBP. A predictive model was constructed and validated using the estimated area under curve (AUC). The indices related to the survival of cirrhotic patients were also analyzed. RESULTS: A total of 413 cirrhotic patients were enrolled in the study, of whom 329 were decompensated and 84 were compensated. 52 patients complicated and patients with SBP had a poorer Child-Pugh score (P < 0.05). Patients with SBP had a greater proportion of malignancies than those without SBP(P < 0.05). The majority of laboratory test indicators differed significantly between patients with and without SBP (P < 0.05). Albumin, neutrophil-to-lymphocyte ratio (NLR), and ferritin-to-neutrophil ratio (FNR) were found to be independently associated with SBP in decompensated cirrhotic patients using LASSO algorithms, and logistic regression analysis. The model established by the three indices showed a high predictive value with an AUC of 0.808. Furthermore, increased neutrophils, ALP, and C-reactive protein-to-albumin ratio (CAR) were associated with the shorter survival time of patients with decompensated cirrhosis, and the combination of these indices showed a greater predictive value for cirrhotic patients. CONCLUSIONS: The present study identified FNR as a novel index in the diagnosis of SBP in decompensated patients with cirrhosis. A model based on neutrophils, ALP and CAR showed high performance in predicting the prognosis of patients with decompensated cirrhosis.

A new dyslipidemia-based scoring model to predict transplant-free survival in patients with hepatitis E-triggered acute-on-chronic liver failure.

BACKGROUND/AIMS: Hepatitis E virus (HEV)-triggered acute-on-chronic liver failure (ACLF) has unacceptably high short-term mortality. However, it is unclear whether the existing predictive scoring models are applicable to evaluate the prognosis of HEV-triggered ACLF. METHODS: We screened datasets of patients with HEV-triggered ACLF from a regional tertiary hospital for infectious diseases in Shanghai, China, between January 2011 and January 2021. Clinical and laboratory parameters were recorded and compared to determine a variety of short-term mortality risk factors, which were used to develop and validate a new prognostic scoring model. RESULTS: Out of 4952 HEV-infected patients, 817 patients with underlying chronic liver disease were enrolled in this study. Among these, 371 patients with HEV-triggered ACLF were identified and allocated to the training set (n = 254) and test set (n = 117). The analysis revealed that hepatic encephalopathy (HE), ascites, triacylglycerol and apolipoprotein A (apoA) were associated with 90-day mortality (P < 0.05). Based on these significant indicators, we designed and calculated a new prognostic score = 0.632 × (ascites: no, 1 point; mild to moderate, 2 points; severe, 3 points) + 0.865 × (HE: no, 1 point; grade 1-2, 2 points; grade 3-4, 3 points) - 0.413 × triacylglycerol (mmol/L) - 2.171 × apoA (g/L). Compared to four well-known prognostic models (MELD score, CTP score, CLIF-C OFs and CLIF-C ACLFs), the new scoring model is more accurate, with the highest auROCs of 0.878 and 0.896, respectively, to predict 28- and 90-day transplantation-free survival from HEV-triggered ACLF. When our model was compared to COSSH ACLF IIs, there was no significant difference. The test data also demonstrated good concordance. CONCLUSIONS: This study is one of the first to address the correlation between hepatitis E and serum lipids and provides a new simple and efficient prognostic scoring model for HEV-triggered ACLF.

Emergency medicine updates: Spontaneous bacterial peritonitis.

INTRODUCTION: Spontaneous bacterial peritonitis (SBP) is a common infection in patients with cirrhosis and ascites and is associated with significant risk of mortality. Therefore, it is important for emergency medicine clinicians to be aware of the current evidence regarding the diagnosis and management of this condition. OBJECTIVE: This paper evaluates key evidence-based updates concerning SBP for the emergency clinician. DISCUSSION: SBP is commonly due to Gram-negative bacteria, but infections due to Gram-positive bacteria and multidrug resistant bacteria are increasing. The typical presentation of SBP includes abdominal pain, worsening ascites, fever, or altered mental status in a patient with known liver disease; however, some patients may be asymptomatic or present with only mild symptoms. Paracentesis is the diagnostic modality of choice and should be performed in any patient with ascites and concern for SBP or upper gastrointestinal bleeding, or in those being admitted for a complication of cirrhosis. Ultrasound should be used to optimize the procedure. An ascites absolute neutrophil count (ANC) ≥ 250 cells/mm3 is diagnostic of SBP. Ascitic fluid should be placed in blood culture bottles to improve the culture yield. Leukocyte esterase reagent strips can be used for rapid diagnosis if available. While many patients will demonstrate coagulation panel abnormalities, routine transfusion is not recommended. Management traditionally includes a third-generation cephalosporin, but specific patient populations may require more broad-spectrum coverage with a carbapenem or piperacillin-tazobactam. Albumin infusion is associated with reduced risk of renal impairment and mortality. CONCLUSIONS: An understanding of literature updates can improve the care of patients with suspected SBP.

Liver cirrhosis following oxaliplatin-based adjuvant chemotherapy for rectal cancer.

INTRODUCTION: Oxaliplatin is a third-generation platinum-based antineoplastic drug that is widely used to treat patients with colorectal cancer. Reported adverse reactions include hepatic sinusoidal obstruction syndrome and liver fibrosis, but there are few reports of cirrhosis associated with chemotherapy. In addition, the pathogenesis of cirrhosis remains unclear. CASE REPORT: We report a case of suspected oxaliplatin-induced liver cirrhosis, an adverse reaction that has not been previously reported. MANAGEMENT AND OUTCOME: A 50-year-old Chinese man was diagnosed with rectal cancer and underwent laparoscopic radical rectal cancer surgery. The patient had a history of schistosomiasis, but history and serology showed no evidence of chronic liver disease. However, after five oxaliplatin-based chemotherapy cycles, the patient presented dramatic changes in liver morphology and developed splenomegaly, massive ascites, and elevated CA125 levels. Four months after discontinuing oxaliplatin, the patient's ascites had decreased significantly and CA125 levels declined from 505.3 to 124.6 mU/mL. After 15 weeks of follow-up, CA125 levels decreased to the normal range, and there has been no increase in ascites in this patient. DISCUSSION: Oxaliplatin-induced cirrhosis may be a serious complication and should be discontinued based on clinical evidence.

Comparison of the imaging and clinical characteristics between Initial and Recurrent Alcoholic Acute Pancreatitis: a retrospective cross-sectional study.

MATERIALS: Patients with alcoholic acute pancreatitis in our hospital were recruited from Jan 2019 to July 2022 and divided into IAAP and RAAP groups. All patients underwent Contrast-Enhanced Computerized Tomography (CECT) or Magnetic Resonance Imaging (MRI) after administration. Imaging manifestations, local complications, severity scores on the Modified CT/MR Severity Index (MCTSI/MMRSI), Extrapancreatic Inflammation on CT/MR (EPIC/M), clinical severity [Bedside Index for Severity in Acute Pancreatitis (BISAP) Acute Physiology and Chronic Health Evaluation (APACHE-II)], and clinical prognosis were compared between the two groups.Results: 166 patients were recruited for this study, including 134 IAAP (male sex 94%) and 32 RAAP patients (male sex 100%). On CECT or MRI, IAAP patients were more likely to develop ascites and Acute Necrosis collection (ANC) than RAAP patients (ascites:87.3%vs56.2%; P = .01; ANC:38%vs18.7%; P < .05). MCTSI/MMRSI and EPIC/M scores were higher in IAAP than in RAAP patients(MCTSI/MMRSI:6.2vs5.2; P < .05; EPIC/M:5.4vs3.8; P < .05).Clinical severity scores (APACHE-II and BISAP), length of stay, and systemic complications [Systemic Inflammatory Response Syndrome (SIRS), respiratory failure] were higher in the IAAP group than in the RAAP group (P < .05). No mortality outcomes were reported in either group while hospitalized.Conclusions: Patients with IAAP had more severe disease than those with RAAP. These results may be helpful for differentiating care paths for IAAP and RAAP, which are essential for management and timely treatment in clinical practice.

Intestinal anisakiasis: CT imaging findings-a 10-year descriptive study in a single center.

PURPOSE: The aim of this study was to retrospectively review cases of intestinal anisakiasis diagnosed by CT over a 10-year period and to evaluate imaging findings associated with the disease. METHODS: This retrospective study included 71 patients with clinical suspicion of intestinal anisakiasis in whom an abdominopelvic computed tomography (CT) was performed at a single institution between June 2011 and December 2021. To identify the cases, we used medical term search engines and the hospital's radiology case database. Clinical information was gathered from the medical records. A radiologist with five years of experience reviewed and analyzed the CT images to determine the characteristic findings of intestinal anisakiasis. RESULTS: The study included 47 confirmed cases of intestinal anisakiasis. The mean age of the patients was 52 years (range 18-87 years), being more frequent in men than women (26:21). All patients reported ingestion of raw fish, most commonly anchovies in vinegar (30/47, 63,8%). Abdominal pain was the predominant symptom, accompanied by nausea, vomiting, and occasionally fever. The most common clinical suspicions were intestinal obstruction (14/47, 29,8%) and appendicitis (10/47, 21,3%), whereas intestinal anisakiasis was suspected in only 2 cases prior to imaging. CT showed thickening of the bowel wall with submucosal edema in all patients, predominantly involving the ileum (43/47, 91,5%), usually in a relatively long segment (mean of 17,5 cm, range 10-30 cm). Simultaneous involvement of multiple bowel segments was observed in 16 cases (34%). Intestinal obstruction with dilatation of proximal loops (33/47, 70,2%), ascites (45/47, 95,7%), and mesenteric fat striation (32/47, 68,1%) were also common findings. CONCLUSION: This study demonstrates the value of computed tomography in suggesting the diagnosis of intestinal anisakiasis, which often presents with nonspecific clinical manifestations. The characteristic CT findings that provide diagnostic clues are bowel wall thickening with submucosal edema, typically involving a long segment of the ileum, with signs of intestinal obstruction, ascites, and mesenteric fat striation. Simultaneous involvement of several intestinal segments (typically the gastric antrum and right colon) is an additional finding to be considered and may provide a diagnostic clue.

[Comparative analysis of intestinal microbiota distribution characteristics based on metagenomics in patients with hepatitis B cirrhosis with or without ascites].

Objective: To use metagenomic sequencing to compare the differences in intestinal microbiota species and metabolic pathways in patients with hepatitis B cirrhosis with or without ascites and further explore the correlation between the differential microbiota and clinical indicators and metabolic pathways. Methods: 20 hepatitis B cirrhosis cases [10 without ascites (HBLC-WOA), 10 with ascites (HBLC-WA), and 5 healthy controls (HC)] were selected from the previously studied 16S rRNA samples. Metagenome sequencing was performed on the intestinal microbiota samples. The Kruskal-Wallis rank sum test and Spearman test were used to identify and analyse differential intestinal microbiota populations, metabolic pathways, and their correlations. Results: (1) The overall structure of the intestinal microbiota differed significantly among the three groups (R = 0.19, P = 0.018). The HC group had the largest abundance of Firmicutes and the lowest abundance of Proteobacteria at the genus level. Firmicutes abundance was significantly decreased (P(fdr) < 0.01), while Proteobacteria abundance was significantly increased (P(fdr) < 0.01) in patients with cirrhosis accompanied by ascites; (2) LEfSe analysis revealed that 29 intestinal microbiota (18 in the HBLC-WA group and 11 in the HBLC-WOA group) played a significant role in the disease group. The unclassified Enterobacteriaceae and Klebsiella species in the HBLC-WA group and Enterobacteriaceae in the HBLC-WOA group were positively correlated with the Child-Turcotte-Pugh (CTP) score, prothrombin time, and international normalized ratio score and negatively correlated with albumin and hemoglobin levels (P < 0.05). Escherichia and Shigella in the HBLC-WA group were positively correlated with CTP scores (P < 0.05); (3) The correlation analysis results between the KEGG pathway and 29 specific intestinal microbiota revealed that Enterobacteriaceae and arachidonic acid, α-linolenic acid, glycerolipid metabolism, and fatty acid degradation were positively correlated in the lipid metabolism pathway, while most Enterobacteriaceae were positively correlated with branched-chain amino acid degradation and negatively correlated with aromatic amino acid biosynthesis in the amino acid metabolic pathway. Conclusion: A significant increment of Enterobacteriaceae in the intestines of HBLC-WA patients influenced hepatic reserve function and was associated with amino acid and lipid metabolic pathways. Therefore, attention should be paid to controlling the intestinal microbiota to prevent complications and improve the prognosis in patients with hepatitis B cirrhosis, especially in those with ascites.

Acute kidney injury in patients with cirrhosis - practical summary.

Acute kidney injury (AKI) is a relatively common condition in patients with advanced liver disease and which is associated with increased mortality. It mainly affects patients with decompensated cirrhosis, particularly those with advanced portal hypertension and ascites. The dual organ involvement may have different forms. The contributing pathogenetic mechanisms are common and predict a dismal prognosis. Early diagnosis and interventions involving specialists (in particular, hepatologists and nephrologists) are essential to improve outcomes.
