Objectives: The long-term consequences of COVID-19 infection on the gastrointestinal tract remain unclear. Here, we aimed to evaluate the prevalence of gastrointestinal symptoms and post-COVID-19 disorders of gut-brain interaction after hospitalisation for SARS-CoV-2 infection. Design: GI-COVID-19 is a prospective, multicentre, controlled study. Patients with and without COVID-19 diagnosis were evaluated on hospital admission and after 1, 6 and 12 months post hospitalisation. Gastrointestinal symptoms, anxiety and depression were assessed using validated questionnaires. Results: The study included 2183 hospitalised patients. The primary analysis included a total of 883 patients (614 patients with COVID-19 and 269 controls) due to the exclusion of patients with pre-existing gastrointestinal symptoms and/or surgery. At enrolment, gastrointestinal symptoms were more frequent among patients with COVID-19 than in the control group (59.3% vs 39.7%, p, Fondazione Cassa di Risparmio in Bologna; Ministero dell’Istruzione, dell’Università e della Ricerca, MIUR; Korean Society of Neurogastroenterology and Mobility, KSNM; Fondazione del Monte di Bologna e Ravenna: H2020, SC1-BHC-01-2019; United European Gastroenterology, UEG; Fondazione Roma, GB’s contribution to this research was partly supported by funding from Fondazione Cassa di Risparmio in Bologna, the Italian Ministry of Education, University and Research; and Fondazione del Monte di Bologna e Ravenna and European Grant H2020, DISCOvERIE, SC1-BHC-01-2019, We thank the European Society of Neurogastroenterology and Motility, the United European Gastroenterology, and the Rome Foundation for supporting this study.

Due to its extreme virulence, COVID-19 virus has rapidly spread, developing a severe pandemic. SARS-COV-2 mostly affected the respiratory tract, causing a severe acute lung failure. Although the infection of airways, COVID-19 can be associated with chronic and systemic damages still not so much known. The purpose of this research is to collect recent evidence in literature about systemic diseases caused by COVID-19. The format of the present article has features of a systematic case-based review (level of evidence), and it is structured as a case series report (patients of our COVID-19 Medicine Ward have been selected as cases). Data for this review have been selected systematically, taking evidence only from indexed journals and databases: PubMed, Scopus, MEDLINE, and Cochrane systems. Papers chosen included systematic reviews, case series, clinical cases, meta-analysis studies, and RCTs. We start collecting studies since 2003. The main keywords used were “COVID-19” “OR” “SARS” “OR” “SARS – COV 2” “AND” “systemic disease” / “nephropathy” / “cardiac pathology” / “central nervous system.” Clinical cases belong to our COVID-19 Medicine Ward. One of the most severe COVID-19 clinical presentations includes cardiovascular problems, like myocarditis, pericarditis, and acute hearth failure. Cytokine release syndrome caused by COVID-19 develops severe acute kidney failure. It is still unknown the way coronavirus damages the liver, brain, and reproductive system. Considering the majority of the new studies about this pathology, it issues that COVID-19 is considered to be a multi-organ disease.

Bile acid malabsorption (BAM) represents a common cause of chronic diarrhea whose prevalence is under-investigated. We reviewed the evidence available regarding the pathophysiology and clinical management of bile acid diarrhea (BAD). BAD results from dysregulation of the enterohepatic recirculation of bile acids. It has been estimated that 25–33% of patients with functional diarrhea and irritable bowel syndrome with diarrhea have BAM. Currently, the selenium homotaurocholic acid test is the gold standard for BAD diagnosis and severity assessment. However, it is an expensive method and not widely available. The validation of the utility in the clinical practice of several other serum markers, such as 7α-hydroxy-4-cholesten-3-one (C4) and the fibroblast growth factor 19 (FGF19) is ongoing. The first-line treatment of patients with BAD is bile acid sequestrants. Patients that are refractory to first-line therapy should undergo further diagnostics to confirm the diagnosis and to treat the underlying cause of BAD. An early and correct diagnosis of BAD would improve patient’s quality of life, avoiding additional diagnostic tests that burden health care systems. Considering the limited availability and tolerability of specific medications for BAD treatment, future research is awaited to identify other therapeutic approaches, such as gut microbiota modulating therapies.

In patients with colonic diverticulosis, the prevalence of segmental colitis associated with diverticulosis (SCAD) is debated. The aim of this study was to assess the prevalence of SCAD in consecutive patients with diverticulosis in a single tertiary center. Over a six-month period, consecutive adult patients with colonic diverticulosis were included. Patients with endoscopic signs of interdiverticular mucosal inflammation (erythema, friability, and ulcerations) were considered suspected SCAD and underwent multiple biopsy samplings to confirm diagnosis. Clinical features were collected from diverticulosis and suspected SCAD patients. In total, 367 (26.5%) of 1383 patients who underwent colonoscopy presented diverticulosis. Among diverticulosis patients, 4.3% (n = 16) presented macroscopic signs of interdiverticular mucosal inflammation and were identified as suspected SCAD. Compared to that of patients with diverticulosis, the age of suspected SCAD patients was significantly lower (60 ± 12.9 years (41.0–86.0) vs. 70 ± 10.6 years (38.0–93.0)) (p = 0.047). Among patients with suspected SCAD, one patient received a new diagnosis of Crohn’s disease, one had spirochetosis infection, and one presented drug-induced colitis. The remaining patients with suspected SCAD (n = 13) were not confirmed by histology. This observational study suggests that SCAD diagnosis is a challenge in clinical practice due to the heterogeneity of endoscopic findings and lack of stated histological criteria.

The coronavirus disease 19 (COVID-19) infection requires major efforts in healthcare systems, due to the high risk of mortality, particularly in subjects with significant comorbidity (≥ 2 pathologies) and polypharmacy (≥ 5 drugs). The treatment of COVID-19 needs a careful evaluation, to reduce the risk of potentially adverse drug reactions. The aim of the study was to examine the use of computerized prescription support in the management and treatment of the COVID-19 infection. We evaluated n.33 patients (51% females) admitted to the west COVID Low-Medium Intensity of Care of Sant’Andrea Hospital during the period March–April 2020 and n.42 subjects (50% females) admitted to the Internal Medicine ward (as control group), by INTERCheck® and Drug-PIN®. The comorbidity (n. pathologies), polypharmacy (n. drugs), and total INTERCheck score in COVID-19 patients and controls were, respectively (mean ± standard deviation): 5.8 ± 3.8, 7.9 ± 4.5, and 9.2 ± 7.1 and 6.8 ± 2.6, 8.0 ± 2.6, and 4.9 ± 3.8 (statistically significant for comorbidity p

Recent evidence showed that dietary habits play a role as risk factors for the development of diverticular complications. This systematic review aims to assess the effect of dietary habits in the prevention of diverticula complications (i.e., acute diverticulitis and diverticula bleeding) in patients with diverticula disease. PubMed and Scopus databases were searched up to 19 January 2021, 330 records were identified, and 8 articles met the eligibility criteria and were subjected to data extraction. The quality of the studies was evaluated by the Newcastle-Ottawa quality assessment form. No study meets the criteria for being a high-quality study. A high intake of fiber was associated to a decreased risk of diverticulitis or hospitalization due to diverticular disease, with a protective effect for fruits and cereal fiber, but not for vegetable fiber; whereas, a high red meat consumption and a generally Western dietary pattern were associated with an increased risk of diverticulitis. Alcohol use seemed to be associated to diverticular bleeding, but not to recurrent diverticulitis or diverticular complications. Further high-quality studies are needed to better define these associations. It is mandatory to ascertain the role of dietary habits for the development of recurrent acute diverticulitis and diverticular bleeding.

Background Pathogenesis of acute diverticulitis and diverticular bleeding remains poorly defined, and few data compare directly risk factors for these complications. Aims to assess differences in clinical features, lifestyles factors and concurrent drug use in patients with acute diverticulitis and those with diverticular bleeding. Methods Data were obtained from the REMAD Registry, an ongoing 5-year prospective, observational, multicenter, cohort study conducted on 1,217 patients. Patient- and clinical- related factors were compared among patients with uncomplicated diverticular disease, patients with previous acute diverticulitis, and patients with previous diverticular bleeding. Results Age was significantly lower (OR 0.48, 95% CI: 0.34–0.67) and family history of diverticular disease was significantly higher (OR 1.60, 95% CI: 1.11–2.31) in patients with previous diverticulitis than in patients with uncomplicated diverticular disease, respectively. Chronic obstructive pulmonary disease was significantly higher in patients with previous diverticular bleeding as compared with both uncomplicated diverticular disease (OR 8.37, 95% CI: 2.60–27.0) and diverticulitis (OR 4.23, 95% CI: 1.11–16.1). Conclusion This ancillary study from a nationwide Registry showed that some distinctive features identify patients with acute diverticulitis and diverticular bleeding. These information might improve the assessment of risk factors for diverticular complications.

Autoimmune atrophic gastritis (AAG) diagnosis is based on specific histological findings and anti-parietal cell antibodies (PCA) considered the serological hallmark of AAG, although a subgroup of AAG patients may be seronegative.To assess the occurrence and clinical features of seronegative compared to seropositive AAG.This is a cross-sectional study including 516 consecutive adult patients (age 59.6 ± 12.8 years, F:M = 2.2:1) with histologically proven AAG diagnosed in two Italian academic referral centers over the last 10 years. PCA were detected at AAG diagnosis. Variables related to the dependent variable of interest (i.e.PCA-negativity) were assessed by univariate/logistic regression analysis.109/516 AAG patients were seronegative. The mean age of seronegative AAG patients was significantly higher compared to PCA-positive (65.9 ± 14.1vs57.9 ± 15.1 years; p0.0001). The proportion of patients aged 70-79 and ≥80 years were, respectively, lower for PCA-positivity (5.1vs12.8%;21.3vs38.5%;p0.005). Seronegativity was associated with age ≥50 years (OR2.4;95%CI 1.1-5.2), while for other variables (gender, comorbidities, anemia, atrophy severity) no association was found. In a sub-cohort of 101 AAG patients, PCA levels detected by ELISA were inversely correlated with age at AAG diagnosis (rho=-0.250;p = 0.0118).Roughly 20% of patients are seronegative at the time of AAG histological diagnosis and this is more common in elderly individuals.

The new virus called severe acute respiratory syndrome coronavirus 2 (SARSCov-2) causing Coronavirus disease 2019 (COVID-19) has spread quickly in several countries and it has become pandemic. Different types of clinical manifestations are attributed to this infection. Some mechanisms related to the infection regarding the immune response are not still elucidated. Herein we reported a case of a 66-years-old patient affected by myelodysplasia who was referred to our hospital because of clinical and radiological manifestations of viral pneumonia. The clinical course has become complicated due to bacterial secondary over-infection by Pseudomonas aeruginosa during stay in internal medicine unit whilst a persistent positive oral and naso-pharyngeal swab test was reported up to 100 days of admission. The patient had a fast clinical and radiological worsening that led her to be admitted to an intensive care unit. Despite intubation and mechanical ventilation she died in a few days.
