Clinical impact of multidrug-resistant bacterial infections in patients with cirrhosis.

Aim: Recently, the emergency of multidrug-resistant organisms (MDRO) has complicated the management of bacterial infections (BI) in cirrhosis. We aimed to assess their clinical impact on patients with decompensated cirrhosis. Methods: A retrospective study included consecutive cirrhotic patients hospitalized for acute decompensation (AD) between January 2010 and December 2019. Results: A total of 518 AD admissions in 219 patients were included, with 260 BI episodes (50.2%). MDRO prevalence was 38.2% of the total isolates. Recent antibiotic use (OR = 4.91), nosocomial infection (OR = 2.95), and healthcare-associated infection (OR = 3.45) were their main risk factors. MDROs were associated with empiric treatment failure (OR = 23.42), a higher prevalence of sepsis (OR = 4.93), ACLF (OR = 3.42) and mortality. Conclusion: The clinical impact of MDROs was pejorative, with an increased risk of empiric treatment failure, organ failure and death.

In recent years, an increasing spread of multidrug-resistant bacteria had been observed worldwide. The emergence of these strains could represent a major problem in fragile patients such as cirrhotic patients. Over 10 years, our study analyzed the bacteriological profile of cirrhotic patient infections. The multidrug-resistant bacteria prevalence was 38.2%. Exposure to healthcare facilities and recent antibiotic use, were their main risk factors. These strains had a negative impact with an increased risk of treatment failure and death.

New Study Alert! Significant prevalence and negative clinical impact of multidrug-resistant organism (MDRO) infections in patients with cirrhosis. Main risk factors: recent antibiotic use and exposure to healthcare facilities. #cirrhosis #bacterialinfection #antibiotherapy #resistance.

Associated factors with liver fibrosis in rheumatoid arthritis patients treated with methotrexate.

INTRODUCTION: There are conflicting findings on the link between liver fibrosis and cumulative methotrexate dosages. We aimed to determine the frequency of liver fibrosis in rheumatoid arthritis patients treated with methotrexate and to identify its associated factors. METHODS: We conducted a cross-sectional study over 9 months (April-December 2021), including rheumatoid arthritis patients treated with methotrexate. Demographic and clinical data were collected. Liver stiffness was assessed by FibroScan. Fibrosis and significant liver fibrosis were defined as liver stiffness higher than 6 and 7.2 kPa, respectively. Liver tests, albuminemia, lipid profile, and blood glycemia were measured. Metabolic syndrome was also evaluated. Statistical analyses were performed using SPSS. RESULTS: We included 21 men and 47 women. The mean age was 51.60 ± 1.82 years. The mean disease duration was 8.29 ± 6.48 years. The mean weekly intake of methotrexate was 13.76 ± 3.91 mg. The mean methotrexate duration was 4.67 ± 4.24 years. The mean cumulative dose was 3508.87 ± 3390.48 mg. Hypoalbuminemia and metabolic syndrome were found in 34% and 25% of cases. We noted increased alkaline phosphatase levels in four cases. The mean liver stiffness was 4.50 ± 1.53 kPa. Nine patients had liver fibrosis, and four had significant fibrosis. Associated factors with liver fibrosis were as follows: age ≥ 60 years (OR:22.703; 95%CI [1.238-416.487]; p = 0.035), cumulated dose of methotrexate ≥ 3 g (OR: 76.501; 95%CI [2.383-2456.070]; p = 0.014), metabolic syndrome (OR: 42.743; 95%CI [1.728-1057.273]; p = 0.022), elevated alkaline phosphatase levels (OR: 28.252; 95%CI [1.306-611.007]; p = 0.033), and hypoalbuminemia (OR: 59.302; 95%CI [2.361-1489.718]; p = 0.013). CONCLUSION: Cumulating more than 3 g of methotrexate was associated with liver fibrosis in rheumatoid arthritis patients. Having a metabolic syndrome, higher age, hypoalbuminemia, and elevated alkaline phosphatase levels were also likely to be independently associated with liver fibrosis. Key points • Rheumatoid arthritis patients require monitoring hepatic fibrosis when the cumulated dose of methotrexate is above 3 g. • Metabolic syndrome is a risk factor for liver fibrosis, suggesting that its management is necessary to prevent this complication. • Hypoalbuminemia and elevated alkaline phosphatase levels (twice the upper limit) in rheumatoid arthritis patients treated with methotrexate were associated with liver fibrosis.

Endoscopic removal of a transgastric migrated textiloma: a case report.

Aim: Abdominal textiloma is an uncommon postoperative complication which can result in a fistula with luminal migration in the digestive tract. Surgery has been the mainstay method for textiloma removal; however, removal of retained gauze by upper gastrointestinal endoscopy is possible avoiding reoperation. Case report: We report a case of an abdominal textiloma in a 38-year-old male, which migrated into the stomach and was extracted by upper endoscopy. Conclusion: Endoscopic extraction after a luminal migration of the abdominal textiloma in the digestive tract facilitate its management and could avoid surgery.

The diagnosis of abdominal textiloma must be considered in front of unexplained symptoms in patients with a surgical history. Surgery has been the mainstay method for textiloma removal; however, endoscopic removal may be the best option which avoids reoperation. We report a case of an abdominal textiloma in a 38-year-old male, which migrated into the stomach and was extracted by upper endoscopy.

EncephalApp Stroop Test for covert hepatic encephalopathy screening in Tunisian cirrhotic patients.

Background: Covert hepatic encephalopathy (CHE) is underdiagnosed and is difficult to detect. The EncephalApp Stroop test is validated for its screening. The aim of the study was to define Tunisian norms for the test based on healthy controls norms and to estimate the prevalence of CHE in cirrhotic Tunisian patients. Methods: A prospective, multicenter, cross-sectional study was conducted. Ambulatory or hospitalized cirrhotic patients aged 40 years and over were recruited at 11 centers. Healthy subjects aged 40 years and over were recruited at 8 centers. We used a translated Arabic version of the streamlined EncephalApp Stroop test. The task has two components: "Off" and "On" state depending on the discordance or concordance of the stimuli. Results: 142 patients were included. The mean age was 57.26 years [40-86]. 40 (28.17%) of cirrhotic patients who were included were diagnosed as having a minimal hepatic encephalopathy or CHE. Among the ineligible patients, 22 had overt hepatic encephalopathy. If we consider these patients, the overall prevalence rate of CHE was around 24.39% in cirrhotic patients. It was more frequent in women (34.21% vs 25.96%), and in patients whose level of school education is between 6 and 13 years. Its prevalence does not appear to be affected by gender, MELD score, etiology of cirrhosis and age group of patients, as these variables were independent with respective p according to the chi-square test 0.413; 0.736; 0.663 and 0.1. The stroop times (On / Off and On + Off) correlated significantly with each other, are associated significantly and positively with age (respective Pearson coefficients: 0.578; 0.567 and 0.6). The more the age increases, the more the stroop response times increases (p > 10 -3). Conclusions: EncephalApp Stroop test was an efficient screening tool for CHE in Tunisian cirrhotic patients.

Antibiotic Prescribing Patterns for Hospitalized children with Community-Acquired Pneumonia in a Secondary Care Center.

BACKGROUND: Narrow-spectrum antibiotics are recommended as the first-line therapy for management of children hospitalized with community-acquired pneumonia (CAP). There are limited data evaluating the antibiotic prescription patterns for CAP in Saudi Arabia. The goal of this study to report on the antibiotic patterns in children hospitalized with CAP. METHODS: A prospective cross-sectional study was conducted in children aged 1 month to 13 years who were hospitalized with a diagnosis of CAP at King Khalid Hospital in Majmaah, Saudi Arabia, between January 2019 and January 2020. RESULTS: Data from 233 patients were collected. The majority of patients received amoxicillin clavulanate (57.9%), followed by ceftriaxone (30%), azithromycin (20.6%), cefuroxime (6%), ampicillin (2.1%), and piperacillin-tazobactam (2.1%). None of our patients were started on narrow-spectrum therapy. The younger age group (1-3 months) and patients with severe pneumonia were more likely to receive broad-spectrum cephalosporin and have a longer hospital stay (P = .000 and P = .002, respectively). However, the 4 months to 5 years age group was more likely to receive amoxicillin clavulanate (P = .001). Male gender was a significate risk factor for patients with severe pneumonia (P=.013) CONCLUSIONS: We demonstrated the inappropriate use of broad-spectrum therapy in children hospitalized with CAP. Further large multicenter studies are necessary to evaluate the patterns of antibiotic use and implement antimicrobial stewardship programs or quality-improvement projects to improve adherence to guidelines.

Does Anemia Have a Potential Effect on Type 2 Hepatorenal Syndrome?

Background/Aims. Hepatorenal syndrome (HRS) is a form of functional renal failure arising in advanced cirrhosis and is characterized by a poor survival rate. Anemia is frequently observed during the clinical course of cirrhosis. Our study aimed to investigate the hematologic findings in patients with cirrhosis to determine the effects of anemia on renal functions in type 2 HRS and if it was a potential aggravating factor. Materials and Methods. This prospective study, in which all consecutive patients with cirrhosis were enrolled, was performed at a tertiary-level hospital (Military Hospital of Tunis) from January 2019 to June 2019. A total of 9 patients with HRS fulfilled the type 2 HRS diagnostic criteria, and 41 patients with cirrhosis without HRS were included. All data regarding patients were obtained from the medical record. Demographic data, routine hemograms, biochemical, and urinary test results were collected. Models of end-stage liver disease (MELD) and Child-Turcotte-Pugh (CTP) scores were calculated. Results. The most common etiology of cirrhosis was viral hepatitis (66%). According to the CTP score, 23 patients were in the CTP-A stage, 13 in the CTP-B stage, and 14 patients were in the CTP-C stage. Patients with type 2 HRS had significantly lower hemoglobin levels compared with non-HRS stable cirrhosis patients. As hemoglobin levels decreased, renal function worsened on patients with type 2 HRS. Patients with lower hemoglobin levels had poor prognosis and survival compared with patients with higher hemoglobin levels. Logistic regression analysis showed that lower hemoglobin levels and higher MELD and CTP scores were statistically significant for an onset of type 2 HRS. Conclusion. Renal dysfunction is a frequent complication in patients with end-stage chronic liver disease. The role of anemia in aggravating HRS in patients with cirrhosis is explained by hypoxia that can lead to microcirculatory renal ischemia. Other studies are required to determine if anemia is a precipitant factor for HRS or not.

Gastric sarcoidosis: Rare revealing feature of systemic sarcoidosis.

Gastric sarcoidosis is clinically manifest in less than 1% of patients with systemic disease. Stomach is the most commonly involved site. Clinical signs are non-specific. We report the case of a female patient presenting with abdominal pain with no associated symptoms. Upper gastrointestinal endoscopy showed mucosal erosions. Biopsy and histological study revealed the presence of a gastric non-caseating granuloma. No other involvement was found and infectious granulomatosis was ruled out. Patient was treated with corticosteroids with substantial improvement. One year later, the patient presented with respiratory symptoms and joint pain. Chest computed tomography showed multiple mediastinal and bilateral hilar lymphadenopathies. It also highlighted the presence of interstitial lung disease and a 1 cm pulmonary nodule. Histological examination of this nodule revealed non-caseating granuloma. Serum angiotensin converting enzyme level was elevated. Lymphocytic alveolitis was diagnosed with bronchoalveolar lavage. Systemic sarcoidosis with gastric involvement was suggested. Patient was treated with corticosteroids and developed a favourable clinical course. Isolated gastric sarcoidosis is a challenging diagnosis. Histological findings are the key to diagnosis. Other granulomatous diseases need to be excluded especially infectious diseases before establishing the diagnosis of sarcoidosis. Corticosteroids are used in treating gastric sarcoidosis, yet no guidelines exist for the treatment of this rare condition.

Cholestatic hepatitis due to Ecballium elaterium ingestion.

Ecballium elaterium is an herbaceous plant belonging to the Cucurbitaceae family. This plant is fairly common in the Mediterranean regions. It is frequently consumed in infusion, mixture of fruit or even in aerosol in cases of fever or flu. This plant is known for its respiratory and ocular toxicity. Hepatotoxicity has never been described in the literature. We report a case of acute cholestatic hepatitis due to Ecballium elaterium in a 39 years old patient, with no past medical history.

[Predictive factors of response to peginterferon and ribavirin in Tunisians patients with chronic hepatitis C: report of 141 cases]. / Facteurs prédictifs de réponse à la bithérapie pégylée au cours de l'hépatite chronique c dans une population tunisienne: à propos de 141 cas.

BACKGROUND: The current treatment recommendation for chronic hepatitis c is the combination of peginterferon and ribavirin. AIMS: To report our experience in the treatment of chronic hepatitis c and determine the predictive factors of sustained virologic response. METHODS: Analysis of consecutive patients treated with peginterferon and ribavirine from 1st January 2000 and 31st December 2009. results: 141 patients with an average age of 50 years were included. 75 % of the patients were infected by a VHc of genotype 1. 22.6 % of the patients were cirrhotics. 7 % of the patients (n=10) had to stop the treatment because of severe side-effects. A reduction of the dose was indicated for 16 % of the patients (n=23). Among the 117 patients with the end of treatment virologic response, 24 patients (20.5%) relapse during the 6 months after the end of therapy. The sustained virologic response in intention to treat was 66 % (57.9 % in case of genotype 1-4 and 91 % in case of genotype 2-3). In multivariate analysis, 4 independent factors of sustained virologic response were identified: the male gender, a viral genotype not 1, a pre-therapeutic viral load ≤ 600 000 UI / ml and a rapid virologic response. CONCLUSION: Approximately two thirds of the patients with chronic hepatitis c achieved a sustained virologic response with peginterferon and ribavirin. Our results are comparable to those of the literature. They will credibly be improved by the introduction of the new antiviral agents.

[Outcomes of endoscopic gluing with cyanoacrylate glue of bleeding gastric varices]. / Résultats de l'obturation endoscopique des varices gastriques hémorragiques par colle biologique.

BACKGROUND: Gastric variceal bleeding is associated with significant morbidity and mortality. Its optimal treatment is not yet standardized and glue injection is the most often proposed treatment. The longterm results of this technique are still controversial. AIM: To assess the safety and efficacy of gastric variceal glue injection. METHODS: Consecutive patients that underwent glue injection for gastric variceal bleeding in our endoscopy unit, from January 2000 to August 2011, were assessed. RESULTS: Sixteen patients (9 men, 7 women) underwent cyanoacrylate glue injections for gastric variceal bleeding. The median follow-up period of 13 patients was 33 months (three were lost to follow-up). The average age was 60 years (3 - 80 years). All patients had stigmata of recent bleeding at endoscopy. Patients underwent an average of 2 gluing sessions (1-3 sessions). N-butyl-2-cyanoacrylate (Histoacryl ®) was the most often product used. No significant complications from cyanoacrylate injection were observed. No patient had a recurrent variceal bleeding. During the median follow-up period, two patients died. CONCLUSION: Our data suggest that cyanoacrylate injection therapy is safe and effective for the prevention of short- and long-term bleeding from gastric varices.
