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: 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: 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 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]

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]

Clinical practice guidelines drive clinical practice and clinicians rely to them when trying to answer their most common questions. One of the most important position papers in the field of gastro-esophageal reflux disease (GERD) is the one produced by the Lyon Consensus. Recently an updated second version has been released. Mean nocturnal baseline impedance (MNBI) was proposed by the first Consensus to act as supportive evidence for GERD diagnosis. Originally a cut-off of 2292 Ohms was proposed, a value revised in the second edition. The updated Consensus recommended that an MNBI < 1500 Ohms strongly suggests GERD while a value > 2500 Ohms can be used to refute GERD. The proposed cut-offs move in the correct direction by diminishing the original cut-off, nevertheless they arise from a study of normal subjects where cut-offs were provided by measuring the mean value ± 2SD and not in symptomatic patients. However, data exist that even symptomatic patients with inconclusive disease or reflux hypersensitivity (RH) show lower MNBI values in comparison to normal subjects or patients with functional heartburn (FH). Moreover, according to the data, MNBI, even among symptomatic patients, is affected by age and body mass index. Also, various studies have proposed different cut-offs by using receiver operating characteristic curve analysis even lower than the one proposed. Finally, no information is given for patients submitted to on-proton pump inhibitors pH-impedance studies even if new and extremely important data now exist. Therefore, even if MNBI is an extremely important tool when trying to approach patients with reflux symptoms and could distinguish conclusive GERD from RH or FH, its values should be interpreted with caution., Competing Interests: Conflict-of-interest statement: The authors declare that they have no conflict of interest., (©The Author(s) 2024.
