Meta-analysis: Post-COVID-19 functional dyspepsia and irritable bowel syndrome.

INTRODUCTION: The burden of post-COVID-19 functional dyspepsia (FD) and irritable bowel syndrome (IBS) remains unclear. The aim of this meta-analysis was to estimate the rate of post-COVID-19 FD and IBS. METHODS: MEDLINE, Scopus and Embase were searched through 17 December 2022. Studies reporting the incidence of FD and/or IBS in COVID-19 survivors and controls (without COVID-19), when available, according to the Rome criteria, were included. Estimated incidence with 95% confidence intervals (CI) was pooled. The odds ratio (OR) with 95% confidence intervals (CI) was pooled; heterogeneity was expressed as I2 . RESULTS: Ten studies met the inclusion criteria and were included in the analysis. Overall, four studies including 1199 COVID-19 patients were considered for FD. Post-COVID-19 FD was reported by 72 patients (4%, 95% CI: 3%-5% and I2 0%). The pooled OR for FD development (three studies) in post-COVID-19 patients compared to controls was 8.07 (95% CI: 0.84-77.87, p = 0.071 and I2 = 67.9%). Overall, 10 studies including 2763 COVID-19 patients were considered for IBS. Post-COVID-19 IBS was reported by 195 patients (12%, 95% CI: 8%-16%, I2 95.6% and Egger's p = 0.002 test). The pooled OR for IBS development (four studies) in COVID-19 patients compared to controls was 6.27 (95% CI: 0.88-44.76, p = 0.067 and I2 = 81.4%); considering only studies with a prospective COVID-19 cohort (three studies), the pooled OR was 12.92 (95% CI: 3.58-46.60, p < 0.001 and I2 = 0%). CONCLUSIONS: COVID-19 survivors were found to be at risk for IBS development compared to controls. No definitive data are available for FD.

Post-Covid-19 Gastro-Intestinal Disturbances.

BACKGROUND: Since the end of 2019, SARS-CoV-2 has been responsible for the multisystemic hyper-inflammatory disease, namely, COVID-19, as a majorly impactful pandemic. Gastrointestinal (GI) symptoms occurring during and after disease are gaining increasing attention among experts. METHODS: We briefly review and comment on preliminary and recent evidences on prevalence, pathophysiology, and perspective treatment options for GI disturbances during and after COVID-19. RESULTS: Several reports from the literature show a significant portion of COVID-19 patients suffering from GI symptoms both at the early stages of the disease and after the end of it, sometimes for several months, namely "long-COVID-19 " patients, irrespective of vaccination. An unsolved issue regarding COVID-19 is the association between GI symptoms and the outcome of COVID-19 patients. Several studies and metanalyses suggest a worse evolution of COVID-19 in patients presenting with GI symptoms. However, these data have not been agreed. Indeed, only one uniform observation can be found in the literature: patients with chronic liver disease have a worse outcome from COVID-19 infection. Upper and lower GI symptoms have similarities with postinfectious functional dyspepsia (FD) and irritable bowel syndrome (IBS). FD and IBS following infection are recognized as a pathophysiological factor, which is a gut microbial quali- and quantitative unbalance, namely dysbiosis. Furthermore, several preliminary reports and ongoing clinical trials have shown gut microbiota modulation by pre-, pro- and post-biotics to be effective in changing and preventing COVID-19 natural course. CONCLUSION: GI symptoms characterize both long- and non-long-COVID-19 with a potentially significant impact on its natural course. Gut microbiota modulation seems to be a sensible target for disease treatment and/or prevention.

Functional Disorders of the Gastrointestinal Tract During the Pandemic of a New Coronavirus Infection

Aim. To analyze the literature data devoted to the study of the features of functional gastrointestinal diseases (FGID) during the pandemic of a new coronavirus infection. Key findings. Measures taken in connection with the pandemic of COVID-19 infection (introduction of lockdown, social isolation) leads to an increase in the level of depression and anxiety and, as a consequence, to an increase in the frequency and prevalence of functional dyspepsia (FD) and irritable bowel syndrome (IBS), as well as an increase in the severity of clinical symptoms of these diseases. In turn, the overcoming of COVID-19 infection contributes to an increase in the permeability of the mucous membrane of the gastrointestinal tract and the occurrence of its inflammatory changes, which lead to the development of postinfectious (postcovid) FD and postinfectious (postcovid) IBS. Conclusion. The problem of functional gastrointestinal diseases during the pandemic of a new coronavirus infection is very important and requires further research. © 2022 Russian Journal of Gastroenterology, Hepatology, Coloproctology

Anxiety level and functional dyspepsia incidence during COVID-19 pandemic

The adaptation process of the learning system, the hospital environment, and the high risk of COVID-19 infection can be stressors for anxiety in clinical clerkship. Through the brain-gut–axis, the interaction of psychological factors, such as anxiety, can trigger symptoms related to functional dyspepsia. This study aimed to determine the relationship between anxiety levels and functional dyspepsia during the COVID-19 pandemic among clinical clerkship students. This research was conducted on clinical clerkship students/young doctors in 2021. This was an observational analytic study with a cross-sectional approach and involved 131 respondents. The hamilton anxiety rating scale (HARS) questionnaire was utilized to quantify the level of anxiety, while functional dyspepsia was measured based on Rome IV criteria. The data were analyzed by the Lambda (λ) coefficient of correlation test. This study revealed a significant relationship between anxiety level and functional dyspepsia during the COVID-19 pandemic. © 2023, Intelektual Pustaka Media Utama. All rights reserved.

Post-infection functional gastrointestinal disorders following coronavirus disease-19: A case-control study.

BACKGROUND AND AIM: Because acute infectious gastroenteritis may cause post-infection irritable bowel syndrome and functional dyspepsia and the severe acute respiratory syndrome coronavirus-2 affects gastrointestinal (GI) tract, coronavirus disease-19 (COVID-19) may cause post-infection-functional GI disorders (FGIDs). We prospectively studied the frequency and spectrum of post-infection-FGIDs among COVID-19 and historical healthy controls and the risk factors for its development. METHODS: Two hundred eighty patients with COVID-19 and 264 historical healthy controls were followed up at 1 and 3 months using translated validated Rome Questionnaires for the development of chronic bowel dysfunction (CBD), dyspeptic symptoms, and their overlap and at 6-month for IBS, uninvestigated dyspepsia (UD) and their overlap. Psychological comorbidity was studied using Rome III Psychosocial Alarm Questionnaire. RESULTS: At 1 and 3 months, 16 (5.7%), 16 (5.7%), 11 (3.9%), and 24 (8.6%), 6 (2.1%), 9 (3.2%) of COVID-19 patients developed CBD, dyspeptic symptoms, and their overlap, respectively; among healthy controls, none developed dyspeptic symptoms and one developed CBD at 3 months (P < 0.05). At 6 months, 15 (5.3%), 6 (2.1%), and 5 (1.8%) of the 280 COVID-19 patients developed IBS, UD, and IBS-UD overlap, respectively, and one healthy control developed IBS at 6 months (P < 0.05 for all except IBS-UD overlap). The risk factors for post-COVID-19 FGIDs at 6 months included symptoms (particularly GI), anosmia, ageusia, and presence of CBD, dyspeptic symptoms, or their overlap at 1 and 3 months and the psychological comorbidity. CONCLUSIONS: This is the first study showing COVID-19 led to post-COVID-19 FGIDs. Post-COVID-19 FGIDs may pose a significant economic, social, and healthcare burden to the world.

Gastrointestinal symptoms and healthcare utilization have increased among patients with functional gastrointestinal and motility disorders during the COVID-19 pandemic.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has led to unprecedented disruptions in healthcare. Functional gastrointestinal and motility disorders (FGIMD) are associated with significant healthcare utilization. The clinical implications of these healthcare disruptions due to the COVID-19 pandemic on clinical outcomes in patients with FGIMD are unclear. METHODS: We performed a retrospective study of patients with three common FGIMD (irritable bowel syndrome [IBS], gastroparesis, functional dyspepsia [FD]) tested for SARS-CoV-2 to describe alterations in gastrointestinal symptoms, medication use, and healthcare utilization during and before the pandemic and factors associated with COVID-19. KEY RESULTS: The prevalence of COVID-19 during the pandemic (03/2020-09/2020) was 3.20% (83/2592) among patients with FGIMD, 3.62% in IBS (57/1574), 3.07% in gastroparesis (23/749), and 2.44% in FD (29/1187) at our institution. Patients with FGIMD had increased abdominal pain, nausea/vomiting, diarrhea, constipation, and weight loss (p < 0.001) along with increased proton pump inhibitor, H2 blocker, and opioid use (p < 0.0001). Both inpatient hospitalizations and outpatient visits (p < 0.0001) and number of diagnostic tests including cross-sectional imaging (p = 0.002), and upper and lower endoscopies (p < 0.0001) were significantly higher during the pandemic as compared to 6 months prior. Diarrhea-predominant IBS was positively (OR 2.37, 95% CI 1.34-4.19, p = 0.003) associated with COVID-19, whereas functional dyspepsia was negatively (OR 0.46, 95% CI 0.27-0.79, p = 0.004) associated. CONCLUSIONS & INFERENCES: Patients with common functional gastrointestinal and motility disorders have reported more gastrointestinal symptoms during the COVID-19 pandemic with concurrent increased medication use and healthcare utilization.

Increased prevalence of gastrointestinal symptoms and disorders of gut-brain interaction during the COVID-19 pandemic: An internet-based survey.

BACKGROUND: Quarantine with social distancing has reduced transmission of COVID-19; however, fear of the disease and these remedial measures cause anxiety and stress. It is not known whether these events have impacted the prevalence of gastrointestinal (GI) symptoms and disorders of brain-gut interaction (DGBI). METHODS: An online platform evaluated the prevalence of GI symptoms during the COVID-19 pandemic. Data collection utilized validated questionnaires and was fully anonymized. Findings were compared with identical data acquired in 2019. The association of results with stress and anxiety was analyzed. RESULTS: Data were collected from 1896 subjects May - August 2019 to 980 non-identical subjects May - June 2020. GI symptoms were reported by 68.9% during the COVID-19 lockdown compared with 56.0% the previous year (p < 0.001). The prevalence of irritable bowel syndrome (26.3% vs. 20.0%; p < 0.001), functional dyspepsia (18.3% vs. 12.7%; p < 0.001), heartburn (31.7% vs. 26.2%, p = 0.002), and self-reported milk intolerance (43.5% vs. 37.8% p = 0.004) was higher during the pandemic. Many individuals reported multiple symptoms. Anxiety was associated with presence of all GI symptoms. High levels of stress impacted functional dyspepsia (p = 0.045) and abdominal pain (p = 0.013). The presence of DGBI (p < 0.001; OR 22.99), self-reported milk intolerance (p < 0.001; OR 2.50), and anxiety (p < 0.001; OR 2.18) was independently associated with increased GI symptoms during COVID-19 pandemic. CONCLUSIONS: The prevalence of GI symptoms was significantly higher during the COVID-19 lockdown than under normal circumstances the previous year. This increase was attributable to increased numbers of patients with DGBI, an effect that was associated with anxiety.

Impacts of the COVID-19 pandemic on functional dyspepsia and irritable bowel syndrome: A population-based survey.

BACKGROUND AND AIM: Functional gastrointestinal disorders are a group of stress-sensitive gut-brain disorders. The COVID-19 outbreak has caused immense stress and anxiety among the general public. Strict measures to counter COVID-19 emergency, including physical distancing, have also taken a toll on physical and mental health. We investigated the impact of the COVID-19 pandemic on the gastrointestinal and psychological symptoms of functional dyspepsia (FD) and irritable bowel syndrome (IBS). METHODS: An online survey was conducted in Japan for a group of randomly assigned panelists from May 26 to 27, 2020. Each respondent answered a questionnaire on stress, physical distancing, and worries about COVID-19. Gastrointestinal symptoms were assessed to diagnose FD and IBS (Rome III), and psychological symptoms were assessed using the Hospital Anxiety and Depression Scale. RESULTS: A total of 5157 subjects were finally enrolled, with FD in 8.5%, IBS in 16.6%, and FD-IBS overlap in 4.0%. For both gastrointestinal and psychological symptoms, respondents with FD-IBS overlap showed the worst scores, followed by IBS-alone, then FD-alone respondents. During the COVID-19 pandemic, 11.9% of respondents reported deterioration and 2.8% reported improvement of gastrointestinal symptoms. FD-IBS overlap, psychological disease comorbidity, and stress at work/school were significantly associated with symptom deterioration. Younger age, commuting by public transport, and work/study from home were associated with symptom improvement. CONCLUSIONS: The COVID-19 pandemic negatively affected FD/IBS subjects, with respondents showing FD-IBS overlap syndrome as the most important independent factor associated with deterioration in gastrointestinal symptoms. Physicians need to take extra care of FD/IBS patients in the post-COVID period.
