Review article: prevention, diagnosis and management of COVID-19 in the IBD patient

The impact of the COVID-19 surge after the end of China's Zero-COVID policy on the health-related quality of life of IBD patients

INTRODUCTION

In December 2019, COVID-19 emerged in Wuhan, Hubei Province, China, and rapidly spread worldwide. On December 2022, the Chinese government ended the zero-COVID policy, leading to a surge in cases and significantly impacting daily life. IBD patients face heightened infection risks and substantial effects on their quality of life during the pandemic.

METHODS

This cross-sectional study collected demographic, COVID-19-related, and HRQoL data from 224 IBD patients who had previously received treatment at Nanjing BenQ Medical Center. Participants completed an online survey between January 9, 2023, and January 23, 2023. The SIBDQ was used to assess HRQoL. Statistical analysis was performed using SPSS version 26.

RESULTS

The study found that UC patients reported higher HRQoL compared to CD patients (p = 0.037). Patients who perceived themselves as less susceptible to COVID-19 had higher scores (p = 0.006 and p = 0.009). Those whose work or study was unaffected also had higher scores (p < 0.001 and p = 0.002). Additionally, irregular medication adherence was associated with lower HRQoL scores (p = 0.014 and p = 0.007). Multivariate linear regression results showed that IBD patients whose work or study was affected during the COVID-19 pandemic scored lower than those who were not affected (p = 0.038; 95% CI, -7.96 to -0.25). Patients who discontinued IBD medication scored higher than those with irregular medication use (p = 0.020; 95% CI, 1.00 to 10.90).

CONCLUSIONS

This study highlights the significant impact of the COVID-19 pandemic on the HRQoL of IBD patients. The findings emphasize the need for integrated care addressing both the physical and psychological aspects of IBD.

COVID-19 IN INFLAMMATORY BOWEL DISEASE: SHOULD WE BE MORE CAREFUL WITH THE USE OF SALICYLATES?

BACKGROUNDS

Fortunately, much has been studied about COVID-19 in patients with inflammatory bowel diseases (IBD). Evidence suggests that these patients do not appear to be at increased risk of severe COVID-19. However, there are still some uncertainties regarding the clinical manifestations of COVID-19 in patients with immune-mediated diseases.

OBJECTIVE

This study aimed to describe the main symptoms of COVID-19 and their frequency in IBD patients and evaluate the impact of the IBD therapeutic drugs on clinical presentation of COVID-19 and to determine factors associated with COVID-19 in this population.

METHODS

Adult patients with IBD from three tertiary-care public, teaching hospitals in Ceará, Northeastern Brazil, were evaluated during one scheduled appointment from March to December 2020. Patients with possible or confirmed COVID-19 were compared with patients without COVID-19. Furthermore, incidences of each symptom were evaluated based on the use of IBD therapeutic drugs.

RESULTS

A total of 515 patients with IBD were included in the study: 234 with CD, and 281 with UC. Of these, 174 patients (34%) had possible/confirmed COVID-19 of whom 156 (90%) were symptomatic. Main symptoms were fever (65%) and headache (65%); gastrointestinal symptoms occurred in one third of patients and were higher than COVID-19 in general population. The factors associated with having COVID-19 were female gender (OR 1.71, 95%CI: 1.17-2.50); contact at home (OR 5.07, 95%CI: 3.31-7.78) and outside the home (OR 3.14, 95%CI: 2.10-4.71) with a case of COVID-19; work outside of the home (OR 1.87, 95%CI: 1.26-2.78); family history of COVID-19 (OR 2.29, 95%CI 1.58-3.33) use of salicylate (OR 1.71, 95%CI: 1.17-4.28); and asthma (OR 7.10, 95%CI: 1.46-34.57).

CONCLUSION

IBD patients at high risk of COVID-19 infection may need to avoid salicylate therapy but further studies are necessary to confirm this association.

Life changes, self-prevention, knowledge and mental health among inflammatory bowel disease patients during COVID-19 pandemic: a cross-sectional study

Background

With the COVID-19 pandemic going to be COVID-19 endemic, the negative impact of COVID-19 on the mental health of IBD patients cannot be ignored. This study aimed to investigate the occurrence of anxiety and depression in IBD patients during the COVID-19 pandemic and analyze the factors associated with mental health.

Methods

Patients registered at the IBD center were enrolled. Electronic questionnaires about the IBD patient's demographic information, basic knowledge of COVID-19, public self-prevention measures, daily life changes, and anxiety and depression were distributed.

Results

Two hundred and fifteen IBD patients finished this study and reported to have anxiety (27%) or depression (34%). During the COVID-19 pandemic, 10.2% of IBD patients reported their diet changes, 58.5% of IBD patients changed their daily physical activities from 3.27 ± 3.252 h to 2.30 ± 2.78 h, 33.7% of IBD patients changed their sleeping duration from 7.99 ± 1.322 h to 8.18 ± 1.447 h. IBD patients' waiting time for admission (OR: 3.688, 95%CI: 1.003-13.554), regularly oral medicine administration (OR: 18.407, 95%CI: 1.975-171.530) and diet changes (OR: 6.167, 95%CI: 2.158-17.626) were positively correlated with anxiety or depression. IBD patients' timely periodic infusion of biological agents (OR: 0.586, 95%CI: 0.413-0.830) was negatively correlated with anxiety or depression. IBD patients' knowledge of COVID-19, public self-prevention, physical activities, and sleep duration changes showed no significant correlation with anxiety and depression, all p values > 0.05.

Conclusion

The main factors of IBD patients' mental health were diet changes, waiting time for admission, taking oral medicine regularly, and timely periodic infusions of biological agents. Ensuring the supply of routine treatment and medication for IBD patients and establishing systemic online IBD self-management programs would be the focus of major public health events.

The effectiveness of continuity of care in patients with inflammatory bowel disease: a systematic review

AIM

To investigate the effectiveness of continuity of care in patients with inflammatory bowel disease.

BACKGROUND

The prevalence of inflammatory bowel disease(IBD) is increasing by years, especially in China. Moreover, IBD is prolonged and difficult to heal, which seriously impairs the quality of life of patients. Some studies have identified that continuity of care could contribute to the improvement of the quality of life, but the results remains inconclusive in patients with IBD.

METHODS

PRISMA guidelines was the outline of this study. Review Manager Software (version 5.3) was used to carry out the data analysis. Outcome assessments included quality of life (QoL), remission rates, number of outpatient clinic visits, and medication adherence.

RESULTS

Ultimately, 12 studies involving 2415 patients were brought into this meta-analysis. The results indicated there was no significant difference for continuity of care to improve the QoL in intervention group (SMD = 0.02, 95% CI: -0.08, 0.12). Besides, the remission rates of disease had no difference with those patients in the two groups (OR = 1.07, 95% CI: 0.72, 1.60). However, continued care could contribute to the number of outpatient clinic visits (MD = -0.84, 95% CI: -1.19, -0.49) and patients' adherence to medication significantly (OR = 2.40, 95% CI: 1.16, 4.95).

CONCLUSIONS

IBD patients could benefited from continuity of care with reducing their number of clinic visits and improving medication adherence. Nonetheless, there was no evidence of continuity of care contribute to QoL and remission of disease for these patients.

SARS-CoV-2 vaccination in inflammatory bowel disease (IBD) patients - does treatment for IBD negatively affect SARS-CoV-2 antibodies? A single-centre, prospective study

Introduction

Inflammatory bowel disease (IBD) patients use a wide variety of immunosuppressive drugs, including biologics, but their effect on SARS-CoV-2 vaccine antibody levels remains a mystery.

Aim

We analysed whether the drugs used in the treatment of IBD patients could affect the concentration of SARS-CoV-2 antibodies.

Material and methods

This is a prospective, single-centre evaluation of the persistence of SARS-CoV-2 antibodies after vaccination at various time points: every 2 months throughout the 6th month after the first dose.

Results

We included a total of 346 vaccinated IBD patients in the study. A negative correlation between antibody level and time from full vaccination was confirmed for the following types of therapy: infliximab (rho = -0.32, p < 0.001), adalimumab (rho = -0.35, p = 0.025), and vedolizumab (rho = -0.50, p < 0.001). In the case of other, long-term drug administration, a negative correlation between antibody level and time from full vaccination was confirmed for mesalazine (rho = -0.35, p < 0.001), budesonide (rho = -0.58, p = 0.004), systemic glucocorticoids (rho = -0.58, p < 0.001), and azathioprine (rho = -0.44, p < 0.001).

Conclusions

Due to the immunosuppressive and biological treatment, IBD patients are exposed to a shorter persistence of SARS-CoV-2 antibodies and require booster doses. The role of gastroenterologists in educating patients about the need to continue SARS-CoV-2 vaccination remains crucial.

The Factors Associated with the Development of COVID-19 Symptoms among Employees in a U.S. Healthcare Institution

Healthcare workers have experienced increased occupational health risks caused by COVID-19 disease. The purpose of this project was to examine the relationships between reporting COVID-19 symptoms by employees in a healthcare institution in the United States and employees' demographics, vaccination status, co-morbid conditions, and body mass index (BMI). This project employed a cross-sectional design. It involved the analysis of data on COVID-19 exposure and infection incidents among employees in the healthcare institution. The dataset contained more than 20,000 entries. The results indicate that being female, African American, between 20 and 30 years old, diagnosed with diabetes, diagnosed with chronic obstructive pulmonary disease (COPD), or on immunosuppressive medicines is associated with greater reporting of COVID-19 symptoms by the employees. Furthermore, BMI is associated with reporting COVID-19 symptoms; the higher the BMI, the greater the likelihood of reporting a symptomatic infection. Moreover, having COPD, being 20-30 years old, being 40-50 years old, BMI, and vaccination status were significantly associated with employees reporting symptoms while controlling for other variables associated with reporting the symptoms among the employees. These findings may be applicable to other infectious disease outbreaks or pandemics.

Frequent brushing of teeth inhibits the dissemination of the SARS-CoV-2: the biochemical mechanism

The SARS-CoV-2 virus is primarily transmitted through direct or indirect contact with the mucous membranes of the mouth and nostrils. The presence of SARS-CoV-2 in sputum with a high viral load suggested that maintaining good oral hygiene could be critical in limiting COVID-19 disease. Brushing the teeth frequently and regularly with widely available amphiphilic detergent, sodium lauryl sulfate (SLS)-based toothpastes could help in preventing the spread of SARS-CoV-2. We proposed a community survey-based methodology followed by an in vitro biochemical strategy to test the virucidal potentiality of SLS, an amphiphilic detergent found in these toothpastes. Through biomolecular structure and docking analysis using models of spike protein and SLS, we showed a possible molecular mechanism of action for SLS-enabled viral particle inactivation.

Remote care through telehealth for people with inflammatory bowel disease

BACKGROUND

People with inflammatory bowel disease (IBD) require intensive follow-up with frequent consultations after diagnosis. IBD telehealth management includes consulting by phone, instant messenger, video, text message, or web-based services. Telehealth can be beneficial for people with IBD, but may have its own set of challenges. It is important to systematically review the evidence on the types of remote or telehealth approaches that can be deployed in IBD. This is particularly relevant following the coronavirus disease 2019 (COVID-19) pandemic, which led to increased self- and remote-management.

OBJECTIVES

To identify the communication technologies used to achieve remote healthcare for people with inflammatory bowel disease and to assess their effectiveness.

SEARCH METHODS

On 13 January 2022, we searched CENTRAL, Embase, MEDLINE, three other databases, and three trials registries with no limitations on language, date, document type, or publication status.

SELECTION CRITERIA

All published, unpublished, and ongoing randomised controlled trials (RCTs) that evaluated telehealth interventions targeted at people with IBD versus any other type of intervention or no intervention. We did not include studies based on digital patient information resources or education resources, unless they formed part of a wider package including an element of telehealth. We excluded studies where remote monitoring of blood or faecal tests was the only form of monitoring.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data from the included studies and assessed their risk of bias. We analysed studies on adult and paediatric populations separately. We expressed the effects of dichotomous outcomes as risk ratios (RRs) and the effects of continuous outcomes as mean differences (MDs) or standardised mean differences (SMDs), each with their 95% confidence intervals (CIs). We assessed the certainty of the evidence using GRADE methodology.

MAIN RESULTS

We included 19 RCTs with a total of 3489 randomised participants, aged eight to 95 years. Three studies examined only people with ulcerative colitis (UC), two studies examined only people with Crohn's disease (CD), and the remaining studies examined a mix of IBD patients. Studies considered a range of disease activity states. The length of the interventions ranged from six months to two years. The telehealth interventions were web-based and telephone-based. Web-based monitoring versus usual care Twelve studies compared web-based disease monitoring to usual care. Three studies, all in adults, provided data on disease activity. Web-based disease monitoring (n = 254) is probably equivalent to usual care (n = 174) in reducing disease activity in people with IBD (SMD 0.09, 95% CI -0.11 to 0.29). The certainty of the evidence is moderate. Five studies on adults provided dichotomous data that we could use for a meta-analysis on flare-ups. Web-based disease monitoring (n = 207/496) is probably equivalent to usual care (n = 150/372) for the occurrence of flare-ups or relapses in adults with IBD (RR 1.09, 95% CI 0.93 to 1.27). The certainty of the evidence is moderate. One study provided continuous data. Web-based disease monitoring (n = 465) is probably equivalent to usual care (n = 444) for the occurrence of flare-ups or relapses in adults with CD (MD 0.00 events, 95% CI -0.06 to 0.06). The certainty of the evidence is moderate. One study provided dichotomous data on flare-ups in a paediatric population. Web-based disease monitoring (n = 28/84) may be equivalent to usual care (n = 29/86) for the occurrence of flare-ups or relapses in children with IBD (RR 0.99, 95% CI 0.65 to 1.51). The certainty of the evidence is low. Four studies, all in adults, provided data on quality of life. Web-based disease monitoring (n = 594) is probably equivalent to usual care (n = 505) for quality of life in adults with IBD (SMD 0.08, 95% CI -0.04 to 0.20). The certainty of the evidence is moderate. Based on continuous data from one study in adults, we found that web-based disease monitoring probably leads to slightly higher medication adherence compared to usual care (MD 0.24 points, 95% CI 0.01 to 0.47). The results are of moderate certainty. Based on continuous data from one paediatric study, we found no difference between web-based disease monitoring and usual care in terms of their effect on medication adherence (MD 0.00, 95% CI -0.63 to 0.63), although the evidence is very uncertain. When we meta-analysed dichotomous data from two studies on adults, we found no difference between web-based disease monitoring and usual care in terms of their effect on medication adherence (RR 0.87, 95% CI 0.62 to 1.21), although the evidence is very uncertain. We were unable to draw any conclusions on the effects of web-based disease monitoring compared to usual care on healthcare access, participant engagement, attendance rate, interactions with healthcare professionals, and cost- or time-effectiveness. The certainty of the evidence is very low.

AUTHORS' CONCLUSIONS

The evidence in this review suggests that web-based disease monitoring is probably no different to standard care in adults when considering disease activity, occurrence of flare-ups or relapse, and quality of life. There may be no difference in these outcomes in children, but the evidence is limited. Web-based monitoring probably increases medication adherence slightly compared to usual care. We are uncertain about the effects of web-based monitoring versus usual care on our other secondary outcomes, and about the effects of the other telehealth interventions included in our review, because the evidence is limited. Further studies comparing web-based disease monitoring to standard care for the clinical outcomes reported in adults are unlikely to change our conclusions, unless they have longer follow-up or investigate under-reported outcomes or populations. Studies with a clearer definition of web-based monitoring would enhance applicability, enable practical dissemination and replication, and enable alignment with areas identified as important by stakeholders and people affected by IBD.

Seroprevalence of ANTI-SARS-CoV-2 antibodies in patients with inflammatory bowel disease

Patients with inflammatory bowel disease (IBD) treated with biologic and/or immunosuppressant drugs are at increased risk for opportunistic infections. Seroprevalence studies can confirm the diagnosis of SARS-CoV-2 infections as well as the associated risk factors. This is a descriptive study which primary endpoints were to highlight the prevalence of SARS-CoV-2 antibodies in a cohort of IBD patients in March 2021, and to analyze seroconversion in patients with known COVID-19 infection and its relationship with IBD treatments. Patients filled in a questionnaire about symptoms of COVID-19 infection and clinical information about their IBD. All included patients were tested for SARS-CoV-2 antibodies. 392 patients were included. Among patients with clinical infection, 69 patients (17,65%) were IgG-positive, 286 (73,15%) IgG-negative and 36 (9,21%) indeterminate. In relation to seroconversion among patients under biologic treatment, 13 patients of the 23 with a previous positive CRP developed antibodies (56.5%). However, when the influence of immunosuppressive treatment on the probability of developing antibodies was analyzed, no significant differences were seen between those patients with or without treatment (77.8% vs. 77.1%, p = 0.96). In our cohort of IBD patients, after one year of pandemic, there were 18.64% IgG positive patients, a higher prevalence than the general population (15.7%).

COVID-19 susceptibility and clinical outcomes in inflammatory bowel disease: An updated systematic review and meta-analysis

The susceptibility, risk factors, and prognosis of COVID-19 in patients with inflammatory bowel disease (IBD) remain unknown. Thus, our study aims to assess the prevalence and clinical outcomes of COVID-19 in IBD. We searched PubMed, EMBASE, and medRxiv from 2019 to 1 June 2022 for cohort and case-control studies comparing the prevalence and clinical outcomes of COVID-19 in patients with IBD and in the general population. We also compared the outcomes of patients receiving and not receiving 5-aminosalicylates (ASA), tumour necrosis factor antagonists, biologics, systemic corticosteroids, or immunomodulators for IBD. Thirty five studies were eligible for our analysis. Pooled odds ratio of COVID-19-related hospitalisation, intensive care unit (ICU) admission, or death in IBD compared to in non-IBD were 0.58 (95% confidence interval (CI) = 0.28-1.18), 1.09 (95% CI = 0.27-4.47), and 0.67 (95% CI = 0.32-1.42), respectively. Inflammatory bowel disease was not associated with increased hospitalisation, ICU admission, or death. Susceptibility to COVID-19 did not increase with any drugs for IBD. Hospitalisation, ICU admission, and death were more likely with 5-ASA and corticosteroid use. COVID-19-related hospitalisation (Odds Ratio (OR): 0.53; 95% CI = 0.38-0.74) and death (OR: 0.13; 95% CI = 0.13-0.70) were less likely with Crohn's disease than ulcerative colitis (UC). In conclusion, IBD does not increase the mortality and morbidity of COVID-19. However, physicians should be aware that additional monitoring is needed in UC patients or in patients taking 5-ASA or systemic corticosteroids.

The natural history of COVID-19 in vaccinated inflammatory bowel disease patients

AIM

Assess the characteristics of break through COVID-19 in Inflammatory Bowel Disease (IBD) patients, despite complete vaccination.

METHODS

Patients who reported a COVID-19 at least 3 weeks after complete vaccination were asked to answer an on-line anonymous questionnaire which included patient and disease characteristics, vaccination history, and the evolution of COVID-19.

RESULTS

Among 3240 IBD patients who reported complete vaccination between 1st May 2021 and 30thJune 2022, 402 (12.4%) were infected by SARS Cov-2 [223 male, 216 Crohn's disease (CD), 186 Ulcerative Colitis (UC), mean (SD) age 42.3 (14.9) years, mean (SD) IBD duration 10.1 (9.7) years]. Three hundred and sixty-nine patients (91.8%) were infected once and 33 (8.2%) twice. The mean (SD) time between last vaccination and infection was 4.1 (1.6) months. Overall, 351 (87.3%) patients reported mild constitutional and/or respiratory symptoms, 34 (8.4%) were asymptomatic and only 17 patients (4.2%) required hospitalization. Of hospitalized patients, 2 UC patients died of COVID-19 pneumonia. The remaining hospitalized patients did not need high flow oxygen supply or ICU admission.

CONCLUSIONS

A minority of completely vaccinated IBD patients developed COVID-19 which evolved with mild symptoms and a favorable outcome. These results reinforce the importance of vaccination especially in vulnerable populations.

Diarrhea and Coronavirus Disease 2019 Infection

The global coronavirus disease-2019 (COVID-19) pandemic has caused significant morbidity and mortality, thoroughly affected daily living, and caused severe economic disruption throughout the world. Pulmonary symptoms predominate and account for most of the associated morbidity and mortality. However, extrapulmonary manifestations are common in COVID-19 infections, including gastrointestinal (GI) symptoms, such as diarrhea. Diarrhea affects approximately 10% to 20% of COVID-19 patients. Diarrhea can occasionally be the presenting and only COVID-19 symptom. Diarrhea in COVID-19 subjects is usually acute but is occasionally chronic. It is typically mild-to-moderate and nonbloody. It is usually much less clinically important than pulmonary or potential thrombotic disorders. Occasionally the diarrhea can be profuse and life-threatening. The entry receptor for COVID-19, angiotensin converting enzyme-2, is found throughout the GI tract, especially in the stomach and small intestine, which provides a pathophysiologic basis for local GI infection. COVID-19 virus has been documented in feces and in GI mucosa. Treatment of COVID-19 infection, especially antibiotic therapy, is a common culprit of the diarrhea, but secondary infections including bacteria, especially Clostridioides difficile, are sometimes implicated. Workup for diarrhea in hospitalized patients usually includes routine chemistries; basic metabolic panel; and a complete hemogram; sometimes stool studies, possibly including calprotectin or lactoferrin; and occasionally abdominal CT scan or colonoscopy. Treatment for the diarrhea is intravenous fluid infusion and electrolyte supplementation as necessary, and symptomatic antidiarrheal therapy, including Loperamide, kaolin-pectin, or possible alternatives. Superinfection with C difficile should be treated expeditiously. Diarrhea is prominent in post-COVID-19 (long COVID-19), and is occasionally noted after COVID-19 vaccination. The spectrum of diarrhea in COVID-19 patients is presently reviewed including the pathophysiology, clinical presentation, evaluation, and treatment.

Has the COVID-19 Pandemic Worsened Health-Related Quality of Life of Patients with Inflammatory Bowel Disease? A Longitudinal Disease Activity-Controlled Study

The present longitudinal study aimed to investigate the burden of disease activity change on health-related quality of life (HRQoL) of patients with inflammatory bowel disease (IBD) during the two different pandemic waves in 2020 and 2021. A sample of 221 IBD patients (recruited during March-May 2020 for T0 and March-May 2021 for T1) was included. The psychological impact of the COVID-19 pandemic (Impact of Event Scale-Revised (IES-R)) and HRQoL (Inflammatory Bowel Disease Questionnaire (IBDQ)) were assessed. Post-traumatic COVID-19-related symptoms (IES-R) were not significantly different across the disease activity-related groups. Conversely, IBDQ was consistently higher in patients with persistent, quiescent disease activity compared to the other groups, as expected. Even after controlling for baseline IES-R, repeated-measures ANCOVA showed a non-significant main effect of time (p = 0.60) but a significant time-per-group interaction effect with a moderate effect size (η2 = 0.08). During the two different phases of pandemic restrictions, IBD-specific HRQoL was modified by disease-related factors such as disease activity, rather than by the post-traumatic symptoms of COVID-19. This lends further weight to the need for developing an evidence-based, integrated, biopsychosocial model of care for patients with IBD to identify subjective and objective factors that affect the burden of disease.

Risk of COVID-19 Infection After Full Immunization in Patients With Inflammatory Bowel Disease on Treatment: A Research Network Analysis

BACKGROUND

Acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is an issue in treating patients with Inflammatory Bowel Disease (IBD) due to concerns for infection risk and poor post-vaccination antibody response. We examined the potential impact of IBD treatments on SARS-CoV-2 infection rates after full immunization against COVID-19.

METHODS

Patients who received vaccines between January 2020 and July 2021 were identified. The post-immunization Covid-19 infection rate at 3 and 6 months was assessed in IBD patients receiving treatment. The infection rates were compared to patients without IBD.  Results: The total number of IBD patients was 143,248; of those (n=9405), 6.6% were fully vaccinated. In IBD patients taking biologic agents/small molecules, no difference in Covid-19 infection rate was found at 3 (1.3% vs. 0.97%, p=0.30) and 6 months (2.2% vs. 1.7%, p=0.19) when compared to non-IBD patients. No significant difference in Covid-19 infection rate was found among patients receiving systemic steroids at 3 (1.6% vs. 1.6%, p=1) and 6 months (2.6% vs. 2.9%, p=0.50) between the IBD and non-IBD cohorts.  Conclusions: The COVID-19 immunization rate is suboptimal among IBD patients (6.6%). Vaccination in this cohort is under-utilized and should be encouraged by all healthcare providers.

Can vitamin D status influence seroconversion to SARS-COV2 vaccines?

Existing data indicate an association between vitamin D deficiency and increased severity of respiratory distress due to COVID-19 infection, especially in high-risk populations. To date, the effect of vitamin D on immunogenicity to SARS-CoV-2 vaccines has been investigated solely in young healthcare workers in a few studies, yielding conflicting findings, yet highlighting that the response to immunization is inversely related to age. Vitamin D status can potentially influence the antibody titers in people with a previous (or naïve) SARS-CoV-2 infection and vaccination, given its role in immune regulatory functions. From this standpoint, vitamin D supplementation can help reduce the risk of SARS-CoV-2 infection, COVID-19 severity/mortality and rebalance immunological function, particularly in subjects with vigorous T lymphocyte responses to COVID-19. However, more research is needed to establish a correlation between vitamin D status and the generation of protective serological responses to SARS-CoV-2 vaccination.

COVID-19 Vaccines for Adults and Children with Autoimmune Gut or Liver Disease

The SARS-CoV-2 pandemic raised many challenges for all patients with chronic conditions and those with autoimmune diseases, both adults and children. Special attention is paid to their immunological status, concomitant diseases, and the need for immunosuppressive therapy. All of these factors may impact their COVID-19 course and outcome. COVID-19 vaccination is accepted as one of the most successful strategies for pandemic control. However, individuals with immune-mediated chronic diseases, including autoimmune liver and gut diseases, have been excluded from the vaccine clinical trials. Therefore, we rely on real-world data from vaccination after vaccine approval for these patients to fill the evidence gap for the long-term safety and efficacy of COVID-19 vaccines in patients with autoimmune gut and liver diseases. Current recommendations from inflammatory bowel disease (IBD) societies suggest COVID-19 vaccination in children older than 5 years old, adults and even pregnant females with IBD. The same recommendations are applied to patients with autoimmune liver diseases. Nevertheless, autoimmune disease patients still experience high levels of COVID-19 vaccine hesitancy, and more studies have to be conducted to clarify this issue.

COVID-19 and inflammatory bowel disease crosstalk: From emerging association to clinical proposal

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can cause coronavirus disease 2019 (COVID-19), an acute respiratory inflammation that has emerged worldwide since December 2019, and it quickly became a global epidemic. Inflammatory bowel disease (IBD) is a group of chronic nonspecific intestinal inflammatory diseases whose etiology has not been elucidated. The two have many overlapping symptoms in clinical presentation, such as abdominal pain, diarrhea, pneumonia, etc. Imbalance of the autoimmune system in IBD patients and long-term use of immunosuppressive drugs may increase the risk of infection; and systemic symptoms caused by COVID-19 may also induce or exacerbate intestinal inflammation. It has been found that the SARS-CoV-2 receptor angiotensin converting enzyme 2, which is highly expressed in the lung and intestine, is an inflammatory protective factor, and is downregulated and upregulated in COVID-19 and IBD, respectively, suggesting that there may be a coregulatory pathway. In addition, the immune activation pattern of COVID-19 and the cytokine storm in the inflammatory response have similar roles in IBD, indicating that the two diseases may influence each other. Therefore, this review aimed to address the following research questions: whether SARS-CoV-2 infection leads to the progression of IBD; whether IBD increases the risk of COVID-19 infection and poor prognosis; possible common mechanisms and genetic cross-linking between the two diseases; new treatment and care strategies for IBD patients, and the feasibility and risk of vaccination in the context of the COVID-19 epidemic.

The Effects of the COVID Pandemic on Patients with IBD: Lessons Learned and Future Directions

The COVID-19 pandemic has caused extended global disruption and changed healthcare behaviour and delivery in patients with inflammatory bowel disease, many of whom take immune modifying treatment. Although there were fears about the vulnerability of IBD patients to SARS-CoV-2 infection, we have learnt that overall IBD patients are equivalent to the general population in both viral acquisition and infection outcomes. Overall IBD patients obtain effective vaccine-induced immune responses, although in some groups an additional vaccine dose is required to constitute a primary course. The pandemic has led to significant changes in healthcare delivery, some of which will be enduring. As we grapple with the challenges of recovery, the lessons learnt will continue to be important in optimising outcomes in future outbreaks.

COVID-19 induces gastrointestinal symptoms and affects patients' prognosis

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection caused the pandemic of coronavirus disease 2019 (COVID-19). Gastrointestinal (GI) involvement is common among patients with COVID-19, and GI symptoms can appear earlier than respiratory symptoms. Except for direct infectious effects, patients infected with SARS-CoV-2 are at risk of complications requiring gastroenterological management. Diarrhea is the most common GI symptom in patients with COVID-19 and occurs in up to half of them. Other GI symptoms, such as anorexia, discomfort, nausea, abdominal pain, loss of taste sensation, and vomiting, have been reported. GI symptoms are associated with a poor prognosis. Fecal viral excretion may have clinical significance because of the possible fecal-oral transmission of infection. In the present narrative review article, six different aspects of studies published to date are summarized as follows: GI manifestations of COVID-19, the roles of fecal-oral transmission, poor prognosis of GI symptoms; abnormal abdominal imaging findings, COVID-19 in patients with irritable bowel disease, and prevention and control of SARS-CoV-2 infection in the digestive endoscopy room. Timely understanding of the association between COVID-19 and the digestive system and effective preventive measures are critical to improve this disease and help clinicians take appropriate measures to mitigate further transmission.

Application and Challenges of IoT Healthcare System in COVID-19

The importance of the IoT is increasing in every field of life, and it especially has a significant role in improving the efficiency of the healthcare system. Its demand further increased during COVID-19 to facilitate the patient remotely from their home digitally. Every time the COVID-19 patient visited the doctor for minor complications, it increased the risk of spreading the virus and the cost for the patient. Another alarming situation arose when a patient was in a critical position and may not claim an emergency service from the nearby healthcare system, increasing the death rate. The IoT uses healthcare services to properly monitor COVID-19 patients by using the interconnected network to overcome these issues. Through the IoT, the patient is facilitated by the health care system without spreading the virus, decreasing the death ratio during COVID-19. This paper aims to discuss different applications, technologies, and challenges of the IoT healthcare system, related to COVID-19. Different databases were searched using keywords in PubMed, ResearchGate, Scopus, ACM, Springer, Elsevier, Google Scholar, etc. This paper is trying to discuss, identify, and highlight the useful applications of the IoT healthcare system to provide guidelines to the researchers, healthcare institutions, and scientists to overcomes the hazards of COVID-19 pandemics. Hence, IoT is beneficial by identifying the symptoms of COVID-19 patients and by providing better treatments that use the healthcare system efficiently. At the end of the paper, challenges and future work are discussed, along with useful suggestions through which scientists can benefit from the IoT healthcare system during COVID-19 and in a severe pandemic. The survey paper is not limited to the healthcare system and COVID-19, but it can be beneficial for future pandemics or in a worse situation.

COVID-19: Current Status in Gastrointestinal, Hepatic, and Pancreatic Diseases—A Concise Review

The gastrointestinal tract plays an important role in the pathogenesis of COVID-19. The angiotensin-converting enzyme 2 receptor and the transmembrane protease serine 2 receptor bind and activate SARS-CoV-2 and are present in high concentrations throughout the gastrointestinal tract. Most patients present with gastrointestinal symptoms and/or abnormal liver function tests, both of which have been associated with adverse outcomes. The mechanisms of liver damage are currently under investigation, but the damage is usually transient and nonsevere. Liver transplantation is the only definitive treatment for acute liver failure and end-stage liver disease, and unfortunately, because of the need for ventilators during the COVID-19 pandemic, most liver transplant programs have been suspended. Patients with gastrointestinal autoimmune diseases require close follow-up and may need modification in immunosuppression. Acute pancreatitis is a rare manifestation of COVID-19, but it must be considered in patients with abdominal pain. The gastrointestinal tract, including the liver and the pancreas, has an intimate relationship with COVID-19 that is currently under active investigation.

Effects of Different Biological Therapies on S1/S2 Antibody Response to SARS-CoV-2 Vaccination in a Cohort of Patients with Inflammatory Bowel Disease

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has affected the entire planet. The objectives of our study were to compare responses to the vaccine (Pfizer-Biontech COMIRNATY) in a population of patients with intestinal bowel syndrome undergoing different biological therapies or conventional therapy. The study recruited 390 patients who received the first vaccination dose during the dedicated vaccination campaign for inflammatory bowel disease (IBD) patients. The inclusion criteria were a diagnosis of CD or UC and complete vaccination with the Pfizer–BioNTech COVID-19 (Comirnaty) vaccine. The exclusion criteria were other significant diseases or important therapies under way or contraindications to vaccination according to the European drug surveillance recommendations. Linear rank models were run to assess the association between the different therapies and S1/S2 antibodies at three different times. The models showed that in patients with IBD receiving Vedolizumab a significant increase in mean IgG levels was observed, independently of other therapies and confounding factors (β: 57.45, 95% CI 19.62 to 19.00). This study confirmed the complete antibody response to vaccination against COVID-19 in patients with IBD undergoing biological therapy—particularly Vedolizumab treatment—but also a reduced immune response due to concomitant steroid therapy.

COVID-19 Vaccination in Inflammatory Bowel Disease (IBD)

Vaccines against SARS-CoV-2 are believed to play a key role in the suppression of the COVID-19 pandemic. However, patients suffering from inflammatory bowel diseases (IBD) were excluded from SARS-CoV-2 vaccines trials. Therefore, concerns regarding vaccination efficacy and safety among those patients were raised. Overall, vaccination is well tolerated in the IBD population, and different gastroenterological societies recommend vaccinating patients with IBD at the earliest opportunity to do so. Nevertheless, very little is known about the safety of COVID-19 vaccines in special IBD populations such as pregnant and breastfeeding women or pediatric patients, and further research on this matter is crucial. The available data on vaccine efficacy are promising and show high seroconversion rates in IBD patients on different immune-modifying therapies. However, patients treated with high doses of systemic corticosteroids, infliximab or infliximab and immunomodulators may have a blunted response to the vaccination. The data on COVID-19 vaccination willingness among patients with IBD are conflicting. Nevertheless, vaccine effectiveness and safety are reported to be the most common reasons for hesitancy. This review examines the effectiveness and safety of COVID-19 vaccines and describes vaccination willingness and the reasons for potential hesitancy among patients with IBD.

Susceptibility of Patients with Inflammatory Bowel Disease to COVID-19 Compared with Their Households

BACKGROUND: Immunosuppressive agents used in the treatment of inflammatory bowel diseases (IBDs) could potentially increase the risk of coronavirus disease 2019 (COVID-19). We aimed to compare COVID-19 frequency in patients with IBD with their households and identify the related risk factors. METHODS: Firstly, a multi-centered, observational study on 2110 patients with IBD and 2110 age-matched household members was conducted to compare COVID-19 frequency. Secondly, the data of patients with IBD and COVID-19 who had called the COVID-19 hotline were added. Multivariable logistic regression was used to evaluate the effect of age, type and severity of IBD, the number of comorbidities, and medications on the frequency of COVID-19 among the patients with IBD. RESULTS: The prevalence of COVID-19 in patients with IBD and household groups was similar (34 [1.61%] versus 35 [1.65%]; P = 0.995). The prevalence of COVID-19 increased from 2.1% to 7.1% in those with three or more comorbidities (P = 0.015) and it was significantly higher in those with severe IBD (P = 0.026). The multivariable analysis only showed a significant association with anti-TNF monotherapy (OR: 2.5, CI: 0.97-6.71, P = 0.05), and other medications were not associated with COVID-19. CONCLUSION: The prevalence of COVID-19 in patients with IBD was similar to the household members. Only patients with IBD receiving anti-TNF monotherapy had a higher risk of COVID-19 susceptibility. This finding could be attributed to the higher exposure to the virus during administration in health care facilities.

Inflammatory Bowel Disease Management during the COVID-19 Pandemic: A Literature Review

BACKGROUND: Coronavirus disease 2019 (COVID-19) caused a global pandemic. Since its start, widespread safety measures have been adopted by nations worldwide. Crohn's disease (CD) and ulcerative colitis are two forms of inflammatory bowel disease (IBD). IBD is a common inflammatory illness with a high worldwide incidence. Its clinical symptoms include stomach discomfort, diarrhea, anorexia, and weight loss. Genetics, microbes, cigarette smoking, appendectomy, lack of personal hygiene, using anti-inflammatory agents, vitamin D deficiency, and stress are the main risk factors for IBD. COVID-19 pandemic raised concerns about the exacerbation of COVID clinical manifestations in patients with IBD and increasing the risk of mortality. During COVID-19 pandemic, intestinal inflammation, and promoting adherence need to be controlled using medications and vaccinations as a primary goal. In this review, we reviewed unique concerns about IBD risk in the population as well as management of the disease, and the effectiveness of vaccination during COVID-19 pandemic.

PREVALENCE AND PREDICTIVE FACTORS ASSOCIATED WITH POSITIVITY OF SARS-COV-2 SEROLOGICAL MARKERS IN PATIENTS WITH INFLAMMATORY BOWEL DISEASE AT AN IBD REFERRAL CENTER

BACKGROUND

Data related to SARS-CoV-2 exposure rates in patients with inflammatory bowel diseases (IBD) are scarce. Objective - Our aim was to determine the prevalence of serological markers of SARS-Cov-2 and the predictive factors for positivity in patients with IBD.

METHODS

This is a cross-sectional, observational study carried out from May to September 2020. SARS-CoV-2 serological markers were determined using chemiluminescence immunoassay in 233 IBD patients without evidence of COVID-19 symptoms. Patient age was 36.6±11.1 years, 118 patients were male (50.6%), and 63.1% had Crohn's disease. Patient clinical data were extracted from individual electronic medical records and complemented by a structured interview.

RESULTS

Twenty-six out of the 233 patients with IBD had positive serum markers for SARS-CoV-2 (11.2%). Female sex (P<0.003), extra-intestinal manifestations (P=0.004), use of corticosteroids (P=0.049), and previous contact with individuals with flu-like symptoms (P<0.001) or confirmed diagnosis of COVID-19 (P<0.001), were associated with a significant increased rate of positive SARS-Cov-2 serological markers. No significant difference was observed regarding to adherence to protection measures and positivity of SARS-Cov-2 serological markers (P>0.05).

CONCLUSION

SARS-CoV-2 previous infection in IBD patients was not that uncommon, and its prevalence was 11.2% in our series. Positivity to SARS-CoV-2 serological markers was associated with female sex, extra-intestinal manifestations, use of corticosteroids, and contact with individuals with suspected or confirmed COVID-19. Studies with longer follow-up periods are needed to confirm these findings.

COVID-19 pandemic and inflammatory bowel disease from patients' perspective: A survey from COVID epicenter in India

Background and Aim

The COVID pandemic and countrywide lockdown has had significant impact on patients with inflammatory bowel disease (IBD), with delay in diagnosis, difficulty in access to healthcare and unavailability of drugs. We conducted a telephonic survey to assess this impact.

Methods

Out of 350, 302 participated in the survey. Demographic data, disease severity at the time of survey, extent of disease, details of therapy, and adherence were noted. A validated questionnaire addressing information source, perception of COVID‐19 situation, contact with healthcare, and adherence to standard precautions was administered telephonically.

Results

Out of 350 contacted patients, 302 (86.28%) patients participated in the survey. Median age of cohort was 39 years. Ulcerative colitis (UC) constituted 79%, 16% Crohn's disease (CD), and 5% IBD‐unclassified. At the time of survey, 86.98% patients with UC were in clinical remission and 75.75% of CD patients were generally well. A total of 115 (38%) cases were nonadherent to therapy due to unavailability of medicines (66.38%), financial constraints (25.21%) and inability to reach healthcare facility (3.6%). Disease flare was seen in 14.2% and correlated well with nonadherence. Existing drug therapy was switched to alternative drug in 70 (23.17%) cases due to unavailability (74%). Social media (52.3%) and television (40.4%) were the common sources of information about the pandemic. Telemedicine platforms (WhatsApp and telephone) were used by 180 (59.6%) patients for consultation with good acceptance (81.6%). 87 (28.8%) patients failed to contact healthcare. Apprehension regarding severe COVID infection was noted in 80% while 29% thought that IBD therapy could increase infection risk. Adherence to wearing mask, hand washing, and social distancing was 100%.

Conclusion

Pandemic resulted in disruption of healthcare visits and medication supply. Majority were concerned about increased risk of COVID‐19 infection and adhered to standard precautions. Mobile phone‐based formats for patient care may be an alternative due to patient acceptance and convenience.

Inflammatory Bowel Disease during COVID-19 Pandemic: A Prospective Cohort Study of Incidence Rate and Patients' Concerns

BACKGROUND: During the coronavirus disease 2019 (COVID-19) pandemic, it is imperative to focus on the concerns of patients with chronic diseases regarding the influence of such conditions and medications prescribed for this purpose on their susceptibility to COVID-19 and its severity. This study aimed to evaluate COVID-19 incidence rate, patients' concerns, sources of information, and medication compliance in a cohort of patients suffering from inflammatory bowel disease (IBD). METHODS: In this prospective cohort study, 214 confirmed cases of IBD were followed up within 8 months up to December 20, 2020. In the confirmed cases of COVID-19, the interviews were repeated 3 months later to assess the post-COVID-19 symptoms and conditions. RESULTS: Among 214 patients with IBD, 113 cases (52.8%) were female, and 169 individuals (79%) were suffering from ulcerative colitis (UC). The mean±SD scores of commitment to standard preventive guidance on COVID-19 were 81.6±19. Moreover, 147 patients (69%) had further stated at least one critical apprehension. The main sources of their information on COVID-19 were physicians (n=89, 41.5%) and websites (n=71, 33.1%). In addition, 10 patients with IBD were diagnosed as confirmed cases of COVID-19, one of them expired due to severe acute respiratory syndrome (SARS). CONCLUSION: The incidence of COVID-19 in the cohort of the patients with IBD in this study was broadly comparable to the general reference population. Tight adherence to physical distancing, and if possible, encouragements of patients with IBD to do remote work along with the provision of virtual care to them cannot be overemphasized. Physicians and websites can also play crucial roles in providing accurate information to patients affected with IBD, especially in terms of reassurances for medication compliance.

An Update on the Status of Vaccine Development for SARS-CoV-2 Including Variants. Practical Considerations for COVID-19 Special Populations

The progress in the development of various vaccine platforms against SARS-CoV-2 have been rather remarkable owing to advancement in molecular and biologic sciences. Most of the current vaccines and those in development focus on targeting the viral spike proteins by generating antibodies of varying spectrum. These vaccines represent a variety of platforms including whole virus vaccines, viral vector vaccines, nucleic acid vaccines representing RNA, DNA, and their hybrid forms.The therapeutic efficacy of these vaccines varies owing to their pharmacodynamic individualities. COVID-19 variants are capable of inducing different pathologic responses and some of which may be resistant to antibodies generated by current vaccines. The current clinical use of these vaccines has been through emergency use authorization until recently. Moreover, the efficacy and safety of these vaccines have been tested in substantial numbers of individuals but studies in special populations that better reflect the global population are pending results. These specialized populations include young children, immunocompromised patients, pregnant individuals, and other specialized groups. Combination approaches, molecularly modified vaccination approaches, and vaccines conferring longer periods of immunity are being currently being investigated, as well as pharmacovigilance studies.The continual transformation of SARS-CoV-2 and its variants are of concern along with the breakthrough infections. These considerations pose new challenges for the development of vaccination platforms. For this purpose, booster doses, combination vaccine approaches, and other modalities are being discussed. This review provides an updated account of currently available vaccines and those in advanced development with reference to their composition and mechanisms of action.A discussion on the use of vaccines in special populations including immunocompromised patients, pregnant women and other specialized populations are also included.

Promising Expectations for Pneumococcal Vaccination during COVID-19

The emergence of new viral infections has increased over the decades. The novel virus is one such pathogen liable for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, popularly known as coronavirus disease 2019 (COVID-19). Most fatalities during the past century's influenza pandemics have cooperated with bacterial co/secondary infections. Unfortunately, many reports have claimed that bacterial co-infection is also predominant in COVID-19 patients (COVID-19 associated co/secondary infection prevalence is up to 45.0%). In the COVID-19 pandemic, Streptococcus pneumoniae is the most common coinfecting pathogen. Half of the COVID-19 mortality cases showed co-infection, and pneumonia-related COVID-19 mortality in patients >65 years was 23%. The weakening of immune function caused by COVID-19 remains a high-risk factor for pneumococcal disease. Pneumococcal disease and COVID-19 also have similar risk factors. For example, underlying medical conditions on COVID-19 and pneumococcal diseases increase the risk for severe illness at any age; COVID-19 is now considered a primary risk factor for pneumococcal pneumonia and invasive pneumococcal disease. Thus, pneumococcal vaccination during the COVID-19 pandemic has become more critical than ever. This review presents positive studies of pneumococcal vaccination in patients with COVID-19 and other medical conditions and the correlational effects of pneumococcal disease with COVID-19 to prevent morbidity and mortality from co/secondary infections and superinfections. It also reports the importance and role of pneumococcal vaccination during the current COVID-19 pandemic era to strengthen the global health system.

Transmembrane serine protease 2 and angiotensin-converting enzyme 2 anti-inflammatory receptors for COVID-19/inflammatory bowel diseases treatment

Inflammatory bowel diseases (IBD) refer to a subgroup of chronic, progressive, long-term, and relapsing inflammatory disorders. IBD may spontaneously grow in the colon, and in severe cases may result in tumor lesions such as invasive carcinoma in inflamed regions of the intestine. Recent epidemiological reports indicate that old age and underlying diseases such as IBD contribute to severity and mortality in patients with coronavirus disease 2019 (COVID-19). Currently, the ongoing COVID-19 pandemic caused serious morbidity and mortality worldwide. It has also been shown that the transmembrane serine protease 2 is an essential factor for viral activation and viral engulfment. Generally, viral entry causes a 'cytokine storm' that induces excessive generation of proinflammatory cytokines/chemokines including interleukin (IL)-6, IL-2, IL-7, tumor necrosis factor-α, and interferon-γ. Future research could concentrate on developing inflammatory immunological responses that are efficient to encounter COVID-19. Current analysis elucidates the role of inflammation and immune responses during IBD infection with COVID-19 and provides a list of possible targets for IBD-regulated therapies in particular. Data from clinical, in vitro, and in vivo studies were collected in English from PubMed, Google Scholar, Scopus, and the Cochrane library until May 2021.

DrugWAS: Drug-wide Association Studies for COVID-19 Drug Repurposing

This study aimed to systematically investigate if any of the available drugs in the electronic health record (EHR) can be repurposed as potential treatment for coronavirus disease 2019 (COVID-19). Based on a retrospective cohort analysis of EHR data, drug-wide association studies (DrugWAS) were performed on 9,748 patients with COVID-19 at Vanderbilt University Medical Center (VUMC). For each drug study, multivariable logistic regression with overlap weighting using propensity score was applied to estimate the effect of drug exposure on COVID-19 disease outcomes. Patient exposure to a drug between 3-months prior to the pandemic and the COVID-19 diagnosis was chosen as the exposure of interest. All-cause of death was selected as the primary outcome. Hospitalization, admission to the intensive care unit, and need for mechanical ventilation were identified as secondary outcomes. Overall, 17 drugs were significantly associated with decreased COVID-19 severity. Previous exposure to two types of 13-valent pneumococcal conjugate vaccines, PCV13 (odds ratio (OR), 0.31, 95% confidence interval (CI), 0.12-0.81 and OR, 0.33, 95% CI, 0.15-0.73), diphtheria toxoid and tetanus toxoid vaccine (OR, 0.38, 95% CI, 0.15-0.93) were significantly associated with a decreased risk of death (primary outcome). Secondary analyses identified several other significant associations showing lower risk for COVID-19 outcomes: acellular pertussis vaccine, 23-valent pneumococcal polysaccharide vaccine (PPSV23), flaxseed extract, ethinyl estradiol, estradiol, turmeric extract, ubidecarenone, azelastine, pseudoephedrine, dextromethorphan, omega-3 fatty acids, fluticasone, and ibuprofen. In conclusion, this cohort study leveraged EHR data to identify a list of drugs that could be repurposed to improve COVID-19 outcomes. Further randomized clinical trials are needed to investigate the efficacy of the proposed drugs.

Long COVID in Inflammatory Bowel Diseases

BACKGROUND AND AIMS

SARS-CoV-2-infected patients can experience long-lasting symptoms even after the resolution of the acute infection. This condition, defined as Long COVID, is now recognized as a public health priority and its negative impact on the quality of life of the patients could be more relevant in individuals with debilitating pathologies. We here evaluated the frequency of Long COVID in patients with inflammatory bowel diseases (IBD).

METHODS

IBD patients afferent for scheduled visits to our tertiary referral center at the Tor Vergata University Hospital, Rome, were recruited from 7 September to 22 October 2021. During the visits, patients were investigated about previous COVID-19 infection and the possible development of Long COVID.

RESULTS

Fifty-three out of 528 IBD patients (10%) have had a SARS-CoV-2 infection. Of these, 21 patients (40%) developed Long COVID, and asthenia was the more frequent symptom as it occurred in nearly two-thirds of patients. Patients with Long COVID were more frequently females, while other clinical and demographic characteristics did not differ between patients with Long COVID and those without Long COVID. In particular, the IBD relapses occurred with the same frequency in the two groups.

CONCLUSIONS

Long COVID appears to be common in IBD patients even though it does not influence the IBD course.

COVID-19 and the Gastrointestinal Tract

Since it was discovered at the end of 2019; the pandemic of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has made a serious public health threat worldwide, with over 175 million confirmed cases reported globally. Even when COVID-19 was initially considered a respiratory disease, it was actually known to be multisystemic, with gastrointestinal involvement a common clinical finding. Furthermore, COVID-19 may affect patients with gastrointestinal comorbidities, being the clinical intersectionality of utmost interest for gastroenterologists; critical care physicians and all the healthcare team taking care of COVID-19 patients. The present article presents a brief review of the reported gastrointestinal manifestations of COVID-19 disease in both previously healthy individuals and in patients with gastrointestinal comorbidities.

COVID-19 in gastroenterology: Where are we now? Current evidence on the impact of COVID-19 in gastroenterology

BACKGROUND

The COVID-19 pandemic has created unprecedented challenges in all fields of society with social, economic, and health-related consequences worldwide. In this context, gastroenterology patients and healthcare systems and professionals have seen their routines changed and were forced to adapt, adopting measures to minimize the risk of infection while guaranteeing continuous medical care to chronic patients.

OBJECTIVE

At this point, it is important to evaluate the impact of the pandemic on this field to further improve the quality of the services provided in this context.

METHODS/RESULTS/CONCLUSION

We performed a literature review that summarizes the main aspects to consider in gastroenterology, during the pandemic crisis, and includes a deep discussion on the main changes affecting gastroenterology patients and healthcare systems, anticipating the pandemic recovery scenario with future practices and policies.

Risk, Course, and Effect of SARS-CoV-2 Infection in Children and Adults with Chronic Inflammatory Bowel Diseases

Susceptibility and disease course of COVID-19 among patients with inflammatory bowel diseases (IBD) are unclear and epidemiological data on the topic are still limited. There is some concern that patients with immuno-mediated diseases such as IBD, which are frequently treated with immunosuppressive therapies, may have an increased risk of SARS-CoV-2 infection with its related serious adverse outcomes, including intensive care unit (ICU) admission and death. Corticosteroids, immunomodulators, and biologic drugs, which are commonly prescribed to these patients, have been associated with higher rates of severe viral and bacterial infections including influenza and pneumonia. It is not known whether these drugs can be so harmful as to justify their interruption during COVID-19 infection or if, on the contrary, patients with IBD can benefit from them. As shown by recent reports, it cannot be excluded that drugs that suppress the immune system can block the characteristic cytokine storm of severe forms of COVID-19 and consequently reduce mortality. Another cause for concern is the up-regulation of angiotensin converting enzyme-2 (ACE2) receptors that has been noticed in these patients, which could facilitate the entry and replication of SARS-CoV-2. The aim of this narrative review is to clarify the susceptibility of SARS-CoV-2 infection in patients with IBD, the clinical characteristics of patients who contract the infection, and the relationship between the severity of COVID-19 and immunosuppressive treatment.

A machine learning approach identifies 5-ASA and ulcerative colitis as being linked with higher COVID-19 mortality in patients with IBD

Inflammatory bowel diseases (IBD), namely Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammation within the gastrointestinal tract. IBD patient conditions and treatments, such as with immunosuppressants, may result in a higher risk of viral and bacterial infection and more severe outcomes of infections. The effect of the clinical and demographic factors on the prognosis of COVID-19 among IBD patients is still a significant area of investigation. The lack of available data on a large set of COVID-19 infected IBD patients has hindered progress. To circumvent this lack of large patient data, we present a random sampling approach to generate clinical COVID-19 outcomes (outpatient management, hospitalized and recovered, and hospitalized and deceased) on 20,000 IBD patients modeled on reported summary statistics obtained from the Surveillance Epidemiology of Coronavirus Under Research Exclusion (SECURE-IBD), an international database to monitor and report on outcomes of COVID-19 occurring in IBD patients. We apply machine learning approaches to perform a comprehensive analysis of the primary and secondary covariates to predict COVID-19 outcome in IBD patients. Our analysis reveals that age, medication usage and the number of comorbidities are the primary covariates, while IBD severity, smoking history, gender and IBD subtype (CD or UC) are key secondary features. In particular, elderly male patients with ulcerative colitis, several preexisting conditions, and who smoke comprise a highly vulnerable IBD population. Moreover, treatment with 5-ASAs (sulfasalazine/mesalamine) shows a high association with COVID-19/IBD mortality. Supervised machine learning that considers age, number of comorbidities and medication usage can predict COVID-19/IBD outcomes with approximately 70% accuracy. We explore the challenge of drawing demographic inferences from existing COVID-19/IBD data. Overall, there are fewer IBD case reports from US states with poor health ranking hindering these analyses. Generation of patient characteristics based on known summary statistics allows for increased power to detect IBD factors leading to variable COVID-19 outcomes. There is under-reporting of COVID-19 in IBD patients from US states with poor health ranking, underpinning the perils of using the repository to derive demographic information.

Administration of COVID-19 vaccines in immunocompromised patients

Since the beginning of vaccination programs against COVID-19 in different countries, several populations such as patients with specific immunological conditions have been considered as the priorities for immunization. In this regard, patients with autoimmune diseases or those receiving immunosuppressive agents and anti-cancer therapies, need special attention. However, no confirmed data is presently available regarding COVID-19 vaccines in these populations due to exclusion from the conducted clinical trials. Given the probable suppression or over-activation of the immune system in such patients, reaching a consensus for their vaccination is critical, besides gathering data and conducting trials, which could probably clarify this matter in the future. In this review, besides a brief on the available COVID-19 vaccines, considerations and available knowledge about administering similar vaccines in patients with cancer, hematopoietic stem cell transplantation, solid organ transplantation, multiple sclerosis (MS), inflammatory bowel disease (IBD), and rheumatologic and dermatologic autoimmune disorders are summarized to help in decision making. As discussed, live-attenuated viruses, which should be avoided in these groups, are not employed in the present COVID-19 vaccines. Thus, the main concern regarding efficacy could be met using a potent COVID-19 vaccine. Moreover, the vaccination timing for maximum efficacy could be decided according to the patient’s condition, indicated medications, and the guides provided here. Post-vaccination monitoring is also advised to ensure an adequate immune response. Further studies in this area are urgently warranted.

Treatment of severe acute ulcerative colitis in SARS-CoV-2 infected patients: report of three cases and discussion of treatment options

In the wake of the coronavirus disease 2019 (COVID-19) pandemic, it is unclear how asymptomatic severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-infected patients who present with acute severe ulcerative colitis (UC) can be treated effectively and safely. Standard treatment regimens consist of steroids, immunomodulatory drugs, and biological therapies, but therapeutic decision-making becomes challenging as there are uncertainties about how to deal with these drugs in patients with COVID-19 and active UC. Importantly, guidelines for this particular group of patients with UC are still lacking. To inform therapeutic decision-making, we describe three consecutive cases of patients with active UC and COVID-19 and discuss their treatments based on theoretical knowledge, currently available evidence and clinical observations. Three patients were identified through our national inflammatory bowel disease network [Initiative on Crohn's and Colitis (ICC)] for whom diagnosis of SARS-CoV-2-infection was established by reverse transcription-polymerase chain reaction (RT-PCR) testing in nasopharynx, stools, and/or biopsies. Acute severe UC was diagnosed by clinical parameters, endoscopy, and histopathology. Clinical guidelines for SARS-CoV-2-negative patients advocate the use of steroids, calcineurin inhibitors, or tumor necrosis factor alpha (TNF-α)-antagonists as induction therapy, and experiences from the current three cases show that steroids and TNF-α-antagonists could also be used in patients with COVID-19. This could potentially be followed by TNF-α-antagonists, vedolizumab, or ustekinumab as maintenance therapy in these patients. Future research is warranted to investigate if, and which, immunomodulatory drugs should be used for COVID-19 patients that present with active UC. To answer this question, it is of utmost importance that future cases of patients with UC and COVID-19 are documented carefully in international registries, such as the SECURE-IBD registry.

Remote care through telehealth for people with inflammatory bowel disease

This is a protocol for a Cochrane Review (intervention). The objectives are as follows:

To identify the communication technologies used for remote healthcare sessions, how they are used, their accessibility, and their potential benefits and drawbacks for people with inflammatory bowel disease.

The complex relationship between viruses and inflammatory bowel disease - review and practical advices for the daily clinical decision-making during the SARS-CoV-2 pandemic

The coronavirus disease 2019 (COVID-19) outbreak emerged in December 2019 in China and rapidly spread worldwide. Inflammatory bowel disease (IBD) patients are likely to be more susceptible to viral infections, and this is significantly influenced by the type of therapy they receive. Thus, issues specifically concerning the medical treatment of IBD patients were shortly addressed at the beginning of the pandemic. However, recently available data on the occurrence and outcome of SARS-CoV-2 infection in IBD patients does not address the concerns raised at the beginning of the pandemic. Growing evidence and the rapid changes happening over the past few weeks have helped elucidate the current situation, contribute to our understanding of the disease, and many previously raised questions could now be answered. We hereby summarise available evidence regarding viral infections and IBD, focusing on SARS-CoV infections, and we provide practical recommendations related to patient management during the COVID-19 pandemic era.

How to manage inflammatory bowel disease during the COVID-19 pandemic: A guide for the practicing clinician

Managing inflammatory bowel disease (IBD) during the coronavirus disease 2019 (COVID-19) pandemic has been a challenge faced by clinicians and their patients, especially concerning whether to proceed with biologics and immunosuppressive agents in the background of a global outbreak of a highly contagious new coronavirus (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2). The knowledge about the impact of this virus on patients with IBD, although it is still scarce, is rapidly evolving. In particular, concerns surrounding medications' impact for IBD on the risk of acquiring SARS-CoV-2 infection or developing COVID-19, and potentially exacerbate viral replication and the COVID-19 course, are a current thinking of both practicing clinicians and providers caring for patients with IBD. Managing patients with IBD infected with SARS-CoV-2 depends on both the clinical activity of the IBD and the occasional development and severity of COVID-19. In this review, we summarize the current data regarding gastrointestinal involvement by SARS-CoV-2 and pharmacologic and surgical management for IBD concerning this infection, and the COVID-19 impact on both the patient's psychological functioning and endoscopy services, and we concisely summarize the telemedicine roles during the COVID-19 pandemic.

Evaluation of a personal protective equipment support programme for staff during the COVID-19 pandemic in London

BACKGROUND

The coronavirus disease 2019 pandemic has presented an enormous challenge to healthcare providers worldwide. The appropriate use of personal protective equipment (PPE) has been essential to ensure staff and patient safety. The 'PPE Helper Programme' was developed at a large London hospital group to counteract suboptimal PPE practice. Based on a behaviour change model of capability, opportunity and motivation (COM-B), the programme provided PPE support, advice and education to ward staff.

AIM

Evaluation of the PPE Helper Programme.

METHODS

Clinical and non-clinical ward staff completed a questionnaire informed by the Theoretical Domains Framework and COM-B model. The questionnaire was available in paper and electronic versions. Quantitative responses were analysed using descriptive and non-parametric statistics, and free-text responses were analysed thematically.

FINDINGS

Over a 6-week period, PPE helpers made 268 ward visits. Overall, 261 questionnaires were available for analysis. Across the Trust, 68% of respondents reported having had contact with a PPE helper. Staff who had encountered a PPE helper responded significantly more positively to a range of statements about using PPE than staff who had not encountered a PPE helper. Black and minority ethnic staff were significantly more anxious regarding the adequacy of PPE. Non-clinical and redeployed staff (e.g. domestic staff) were most positive about the impact of PPE helpers. Free-text comments showed that staff found the PPE Helper Programme supportive and would have liked it earlier in the pandemic.

CONCLUSION

The PPE Helper Programme is a feasible and beneficial intervention for providing support, advice and education to ward staff during infectious disease outbreaks.

Risk of COVID 19 in patients with inflammatory bowel diseases compared to a control population

BACKGROUND

It is unclear whether patients with inflammatory bowel disease (IBD) are at increased risk of COVID-19.

OBJECTIVES

This observational study compared the prevalence of COVID-19 symptoms, diagnosis and hospitalization in IBD patients with a control population with non-inflammatory bowel disorders.

METHODS

This multicentre study, included 2733 outpatients (1397 IBD patients and 1336 controls), from eight major gastrointestinal centres in Lombardy, Italy. Patients were invited to complete a web-based questionnaire regarding demographic, historical and clinical features over the previous 6 weeks. The prevalence of COVID-19 symptoms, diagnosis and hospitalization for COVID-19 was assessed.

RESULTS

1810 patients (64%) responded to the questionnaire (941 IBD patients and 869 controls). IBD patients were significantly younger and of male sex than controls. NSAID use and smoking were more frequent in controls. IBD patients were more likely treated with vitamin-D and vaccinated for influenza. Highly probable COVID-19 on the basis of symptoms and signs was less frequent in the IBD group (3.8% vs 6.3%; OR:0.45, 95%CI:0.28-0.75). IBD patients had a lower rate of nasopharyngeal swab-PCR confirmed diagnosis (0.2% vs 1.2%; OR:0.14, 95%CI:0.03-0.67). There was no difference in hospitalization between the groups (0.1% vs 0.6%; OR:0.14, 95%CI:0.02-1.17).

CONCLUSION

IBD patients do not have an increased risk of COVID-19 specific symptoms or more severe disease compared with a control group of gastroenterology patients.

Humoral response to COVID-19 infection in immunosuppressed patients with inflammatory bowel disease

The course of coronavirus 19 (COVID-19) might be determined by certain comorbidities (e.g. diabetes, hypertension and other cardiovascular diseases) and advanced age. Because the impact of immunosuppression on disease severity is not entirely clear, management of patients under immunosuppressive treatment remains controversial. Six cases of inflammatory bowel disease (IBD) patients with COVID-19 on immunosuppressive medication are presented. The aim of this study was to describe patients' clinical manifestation and chronologic development of virus-specific antibodies of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection before and after restart with immunosuppressive/biological therapy as an indicator for a specific immune response. All patients were tested for the presence of SARS-CoV-2-RNA with PCR, were in clinical remission prior to COVID-19 and only one patient continued his immunosuppressive treatment during the COVID-19 infection. Initial symptoms of COVID-19 were pyrexia, diarrhea, cephalea, and dysgeusia and anosmia. No patient needed admission to hospital or ICU. The SARS-CoV-2 antibody development was described to be late in three of the six patients. Late antibody development seems to be more frequent in older patients and in patients with combined immunosuppressive treatment. In this scenario, SARS-CoV-2 antibody testing could be useful prior to restarting immunosuppressive therapy.
