Background: The esophagogastric junction (EGJ) is classified into 3 anatomical subtypes according to lower esophageal sphincter-crural diaphragm (LES-CD) separation. We aimed to assess their relationship to esophageal motility, reflux characteristics, and symptom perception. Methods: We analyzed data from 1740 consecutive patients with typical reflux symptoms, who underwent high resolution manometry and a 24-h pH-impedance study during a 13-year period. A diagnosis of gastroesophageal reflux disease (GERD) was made if acid exposure time (AET) was >6%. EGJ types were classified as 1, 2, or 3, if LES-CD separation was up to 1 cm, 1-3 cm, or =3 cm, respectively. Results: EGJ type distribution was 72.2%, 22.1% and 5.7%, for types 1, 2 and 3, respectively. GERD was diagnosed in 31.2% and was more common among patients with EGJ type 2/3 vs. 1 (P<0.001). Length of LES-CD separation significantly correlated with AET and number of reflux episodes. Patients with type 2 or 3 EGJ more often showed ineffective or absent peristalsis compared with type 1 (P=0.008 and P<0.001 respectively). In the multivariate analysis, EGJ type 2/3 correlated with AET (P=0.001) and reflux episodes (P=0.041) but not with positive symptomatic markers or with ineffective/absent peristalsis. Conclusions: Our study confirms that EGJ anatomical morphology is a strong risk factor for GERD and correlates with both AET and the number of reflux events, though the length of separation is more important than the type. The multivariate analysis revealed that EGJ type 2 or 3 was not correlated with symptom perception or esophageal hypomotility. [ABSTRACT FROM AUTHOR]

Background Functional chest pain (FCP) is characterized by the presence of chest pain of presumed esophageal origin, but with a negative workup on routine investigations, including ruling out gastroesophageal reflux disease (GERD). Antidepressants are frequently prescribed to treat FCP and are presumed to act as neuromodulators of visceral hypersensitivity. However, there is little evidence of their efficacy in patients with FCP. We retrospectively assessed the efficacy of citalopram or amitriptyline vs. no treatment in patients with FCP. Methods Esophageal diseases, including GERD, eosinophilic esophagitis and major esophageal motility disorders, were excluded. Thus, patients with established FCP according to Rome IV criteria were included in the study. Then, patients treated for at least 3 months with citalopram 20 mg, amitriptyline 50 mg, or observation were selected. The primary endpoint was complete disappearance or significant amelioration of symptoms at the end of treatment. Results Over a 5-year period, 102 patients (74 female; mean age 49±10 years) were diagnosed with FCP and were recognized to have received once daily citalopram (n=32), amitriptyline (n=34), or no treatment (n=36). After a 3-month follow up, improvement in chest pain was reported by 16 (47.1%) patients treated with citalopram, 18 (56.3%) patients treated with amitriptyline, and 4 (11.1%) patients without treatment (P=0.02 and 0.01 for no treatment vs. citalopram and amitriptyline therapy, respectively). Conclusion Both citalopram and amitriptyline are effective pharmacological options in the symptomatic relief of almost 50% patients with well characterized FCP. [ABSTRACT FROM AUTHOR]

(1) Introduction/aim: Gastroesophageal reflux disease (GERD) affects 8–33% globally. The gold standard examination technique in diagnosing GERD is 24 h pHmetry ± impedance. Recently, new diagnostic criteria were introduced by the Lyon Consensus for GERD diagnosis. Our aim was to investigate the diagnostic yield of pHmetry + impedance using the Lyon Consensus criteria in a real-world study. (2) Patients and methods: Our study included 249 consecutive patients (M/F: 120/129, mean age 50 ± 15 years) who underwent 24 h pH+ impedance monitoring in our department, during a 5-year period. Epidemiological, endoscopic, clinical, and 24 h pH+ impedance data were retrospectively collected. (3) Results: Typical GERD symptoms were reported by 140/249 (56.2%) patients, whereas 99/249 (39.6%) patients reported various extraesophageal symptoms. Endoscopic findings supportive of GERD based on the Lyon Consensus were present in 42/185 (22.7%). An AET value of >6% was observed in 60/249 (24.1%). GERD diagnosis according to the Lyon Consensus criteria was set in 63/249 (25.3%) patients; a rate significantly lower than that observed by implementing the older criteria (32.1%), p < 0.001. In the multivariate analysis, the existence of endoscopic findings supportive of GERD diagnosis as defined by the Lyon Consensus (p = 0.036), a De Meester score of over 14.7, and the presence of typical GERD symptoms were correlated to GERD diagnosis (p < 0.001, respectively) using the criteria defined for pH–impedance monitoring. (4) Conclusions: Changes in the diagnostic criteria concerning the 24 h pH–impedance monitoring of GERD based on the Lyon Consensus led to a conclusive GERD diagnosis in approximately 25% of the patients. This rate of GERD diagnosis is reduced in comparison to the one confirmed with the use of previously established criteria. [ABSTRACT FROM AUTHOR]

Background Peptic ulcer disease (PUD) is more prevalent in cirrhotics and this may aggravate prognosis. We investigated the prevalence of PUD in cirrhotics and its potential association with Helicobacter pylori (H. pylori) infection, the underlying etiology and severity of liver disease, and other manifestations of portal hypertension (PH). Methods We enrolled consecutive asymptomatic cirrhotic patients who underwent screening endoscopy in a tertiary hospital during a 12-month period. We recorded the presence of PUD and the endoscopic findings associated with PH. H. pylori infection was documented through either histology or CLO-test. The diagnosis of cirrhosis was based on elastography, liver biopsy or a combination of clinical, biochemical and imaging data. Results One hundred patients (M/F: 54/46, mean age: 61±14 years) were included in the analysis. Viral hepatitis (37%) and alcohol (22%) were the most common causes of cirrhosis. Child-Pugh stage was A/B/C: 60/35/5. PUD was found in 19 patients (14 gastric, 5 duodenal). H. pylori infection was diagnosed in 54%. Varices were detected in 59% (39% needed treatment). PH gastropathy was present in 81% (severe in 33%). The presence of PUD was unrelated to the etiology and the severity of liver disease or to other endoscopic manifestations of PH. No correlation was found between PUD and H. pylori infection. Conclusions A high prevalence of PUD was observed in our cirrhotic patients, although they were asymptomatic and had no known risk factors of ulcerogenicity. The value of screening endoscopy for the early diagnosis and treatment of PUD in cirrhotics deserves further investigation. [ABSTRACT FROM AUTHOR]

Chronic hepatitis C virus infection is associated with significant morbidity and mortality, as a result of progression towards advanced natural course stages including cirrhosis and hepatocellular carcinoma. On the other hand, the SVR following successful therapy is generally associated with resolution of liver disease in patients without cirrhosis. Patients with cirrhosis remain at risk of life-threatening complications despite the fact that hepatic fibrosis may regress and the risk of complications such as hepatic failure and portal hypertension is reduced. Furthermore, recent data suggest that the risk of HCC and all-cause mortality is significantly reduced, but not eliminated, in cirrhotic patients who clear HCV compared to untreated patients and nonsustained virological responders. Data derived from studies have demonstrated a strong link between HCV infection and the atherogenic process. Subsequently HCV seems to represent a strong, independent risk factor for coronary heart disease, carotid atherosclerosis, stroke, and, ultimately, CVD related mortality. The advent of new direct acting antiviral therapy has dramatically increased the sustained virological response rates of hepatitis C infection. In this scenario, the cardiovascular risk has emerged and represents a major concern after the eradication of the virus which may influence the life expectancy and the quality of patients’ life.

Background: Preventing disease progression and viral suppression are the main goals of antiviral therapy in chronic hepatitis B (CHB). Liver stiffness measurement (LSM) by transient elastography is a reliable non-invasive method to assess liver fibrosis in patients with CHB. Our aim was to explore factors that may affect changes in LSMs during long term tenofovir (TDF) monotherapy in a well characterized cohort of patients with compensated CHB. Methods: We analyzed serial LSMs in 103 adult patients with CHB who were on TDF monotherapy and had at least three LSMs over a period of 90 months. Results: Twenty-five (24%) patients had advanced fibrosis at baseline. A significant decline in mean LSM between baseline and last visit (8.7 ± 6.2 kPa vs. 6.7 ± 3.3, p = 10− 3) was observed. Twenty-four (23%) patients had progression of liver fibrosis with mean increase in liver stiffness of 2.8 kPa (range: 0.2–10.2 kPa). Multivariate analysis showed that BMI ≥ 25 (OR, 0.014; 95% CI, 0.001–0.157; p = 0.001) and advanced fibrosis (OR, 5.169; 95% CI, 1.240–21.540; p = 0.024) were independently associated with a fibrosis regression of > 30% of liver stiffness compared to baseline value. Conclusions: In CHB patients TDF monotherapy resulted in liver fibrosis regression, especially in patients with advanced fibrosis. Despite the successful antiviral effect of TDF, 1 out of 4 patients had liver fibrosis progression. Obesity and advanced fibrosis at baseline were independently associated with significant liver fibrosis regression. [ABSTRACT FROM AUTHOR]

Background The existing literature does not provide adequate guidance on the diagnosis and management of patients with nonspecific terminal ileitis, while data regarding the percentage of patients who ultimately develop Crohn's disease (CD) are scarce. We evaluated the prevalence and natural course of nonspecific terminal ileitis in patients who underwent colonoscopy during a 11-year period. Methods All patients with endoscopic findings of terminal ileitis and nonspecific histological findings were included. Exclusion criteria were a clinical history of CD or any other disease that can cause terminal ileitis, or a recent history of using drugs implicated in lesions of the terminal ileum. Results From 5353 colonoscopies, 92 patients with nonspecific terminal ileitis were identified (prevalence: 1.7%). Among these patients, 56 (61%) had available follow up for =6 months after the initial endoscopy. Main indications for endoscopy were chronic diarrhea (37.5%), screening endoscopy (23%), and abdominal pain (20%). Sixteen (29%) patients received medical treatment, while recession of symptoms was recorded in 19 of 43 symptomatic patients (44.1%). Twenty-three (41%) of the 56 patients underwent a second endoscopy and 15 (65.2%) cases had persistent endoscopic findings. Eleven (19.6%) of the 56 patients were eventually diagnosed with CD. The probability of CD diagnosis was significantly higher in patients with persistent symptoms (P=0.002) and endoscopic findings at follow up (P=0.038). Conclusions Nonspecific terminal ileitis generally has a benign clinical course. However, patients with persistent symptoms and endoscopic lesions are at increased risk for subsequent development of CD. [ABSTRACT FROM AUTHOR]

Background: We estimated the frequency of cirrhotic cardiomyopathy (CC) using all of the proposed diagnostic criteria, to describe the whole spectrum of cardiac alterations, and to investigate the role of stress in unmasking latent cases of CC. Methods: Ninety consecutive patients were recruited. CC was evaluated using the Montreal, the American Society of Echocardiography 2009 criteria, and the 2019 modified criteria of the CCM consortium. A dobutamine stress test was also performed. Results: Left ventricular diastolic dysfunction (LVDD) was identified in 72 (80%), 36 (40%), and 10 (11.1%) patients based on the above criteria, respectively. None of the patients had right ventricular systolic dysfunction, either at rest or after stress. The dobutamine stress test revealed left systolic dysfunction in 4 (4.5%) patients. There was agreement among the 3 criteria that the presence of LVDD was not associated with the severity of liver disease, using Child-Pugh stage. However, patients with Child-B/C had longer QTc intervals (P=0.004), higher levels of brain natriuretic peptide (P=0.016), and greater echocardiographic E/e' ratio (P<0.001) and E/e'(s) (P=0.003), compared to Child-A patients, while a significant correlation was demonstrated between Child-Pugh score and E/e' (P<0.001), or E/e'(s) (P=0.002). Conclusions: The prevalence of LVDD seems to be lower than previously considered. Right ventricular function seems to remain unimpaired. A dobutamine stress uncovered only a small percentage of patients with left systolic dysfunction. Nevertheless, the aggravation of several sonographic variables during stress, particularly in Child-B/C patients, potentially indicates a higher risk for clinical heart failure during stressful invasive interventions.

Background Patients with primary biliary cholangitis (PBC) who have advanced disease are hypercoagulable, with no thrombophilic factors compared to non-cholestatic cirrhotics. We investigated whether hypercoagulability is present in early-stage PBC. Methods PBC patients with biopsy-documented early disease and healthy controls matched by sex and age were asked to participate in the study. All were evaluated using rotational thromboelastometry (ROTEM), platelet aggregation, and flow cytometry. Four ROTEM parameters were evaluated (clotting time, clotting formation time, α-angle, and maximum clot firmness [MCF]). Platelet aggregation was determined as the maximal change in light transmission after the addition of adenosine diphosphate, collagen and epinephrine. Flow cytometry was used to evaluate the expression of glycoprotein (GP) IIb, GPIIa, and P-selectin on the platelet surface. Results We enrolled 50 individuals in the study (25 PBC patients, 25 controls). Prothrombin time and activated partial thromboplastin time did not differ significantly between PBC patients and controls (P-value not significant). In ROTEM, α-angle and MCF parameters were abnormally elevated in 9 (36%) PBC patients compared to 3 (12%) healthy controls and the difference was statistically significant (P=0.026). Platelet aggregation in PBC patients was not significantly different from controls. In flow cytometry, GPIIb and P-selectin expression was greater in PBC patients than in the control group and the difference was statistically significant (P=0.005 and P=0.006 respectively). Conclusion In this study, we used a combination of sophisticated methods to detect evidence of platelet activation and hypercoagulability in patients with early PBC. Our findings may have important clinical implications and merit further investigation. [ABSTRACT FROM AUTHOR]
