Association between 5-aminosalicylates in patients with IBD and risk of severe COVID-19: an artefactual result of research methodology?

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.

Managing IBD in the COVID-19 era

Over the last 2 years the lives of millions have changed because of the emergence of Coronavirus disease 2019 (COVID-19). Patients living with inflammatory bowel disease (IBD) represent a sizable population with their own sets of challenges to providers in the wake of so much uncertainty. The Centers for Disease Control considers immunocompromised individuals at higher risk of infection and complications from COVID-19. Early in the pandemic, the specific risks for IBD patients were unclear as guidance was based on expert opinion regarding the management of IBD during a COVID-19 era. Fortunately, after considerable work in the field, the overwhelming evidence suggests that IBD patients as a whole do not appear to be at increased risk for more severe disease from COVID-19. Certain risk factors such as age, steroids, comorbidities, combination immunomodulatory therapy, and IBD disease activity have been associated with worse outcomes. Most IBD medications are low risk, with the exception of immunomodulator monotherapy and combination therapy with thiopurine and anti-TNF. Vaccination remains safe and effective for all IBD patients, although additional booster doses may be necessary, particularly in patients taking anti-TNF agents.

COVID-19 and Inflammatory Bowel Disease

The COVID-19 pandemic caused by the SARS-CoV-2 virus represents an unprecedented global health crisis. Safe and effective vaccines were rapidly developed and deployed that reduced COVID-19-related severe disease, hospitalization, and death. Patients with inflammatory bowel disease are not at increased risk of severe disease or death from COVID-19, and data from large cohorts of patients with inflammatory bowel disease demonstrate that COVID-19 vaccination is safe and effective. Ongoing research is clarifying the long-term impact of SARS-CoV-2 infection on patients with inflammatory bowel disease, long-term immune responses to COVID-19 vaccination, and optimal timing for repeated COVID-19 vaccination doses.

The Impact of COVID-19 on Patients with IBD in a Prospective European Cohort Study

BACKGROUND AND AIMS

There are concerns regarding the potential impact of the COVID-19 outbreak on patients with inflammatory bowel disease [IBD]. We report on the impact of the COVID-19 outbreak in a European prospective cohort study of patients with IBD.

PATIENTS AND METHODS

We prospectively collected data from 5457 patients with IBD nested in the ongoing I-CARE project and still followed up in April 2020, with monthly online monitoring of clinical activity, treatment, imaging and endoscopy. Investigators were also contacted to report incidental cases.

RESULTS

In total, 233 [4.3%] reported COVID-19 and 12 [0.2%] severe COVID-19, with no COVID-19 deaths. The risk of COVID-19 in patients with IBD was not increased compared to the general population (standardized incidence ratio [SIR]: 1.18, 95% confidence interval [CI] [1.03-1.34], p = 0.009), as well as the risk of severe COVID-19 (SIR: 0.69, 95% CI [0.35-1.20], p = 0.93). We did not observe any negative impact of the different IBD-related medication on the risk of either COVID-19 or severe COVID-19. In 2020, the COVID-19 outbreak resulted in a drastic decrease in endoscopic and imaging procedures from March to May 2020 compared to 2018 and 2019. No impacts on clinical IBD disease activity as well as ongoing treatment were noted.

CONCLUSION

No increases in either COVID-19 or severe COVID-19 incidences were observed in patients with IBD. There was no impact of COVID-19 on IBD-related medication and clinical activity. Access to endoscopy and imaging was restricted during the first months of the first COVID-19 outbreak.

Risk Factors for COVID-19 in Inflammatory Bowel Disease: A National, ENEIDA-Based Case-Control Study (COVID-19-EII)

(1) Scant information is available concerning the characteristics that may favour the acquisition of COVID-19 in patients with inflammatory bowel disease (IBD). Therefore, the aim of this study was to assess these differences between infected and noninfected patients with IBD. (2) This nationwide case−control study evaluated patients with inflammatory bowel disease with COVID-19 (cases) and without COVID-19 (controls) during the period March−July 2020 included in the ENEIDA of GETECCU. (3) A total of 496 cases and 964 controls from 73 Spanish centres were included. No differences were found in the basal characteristics between cases and controls. Cases had higher comorbidity Charlson scores (24% vs. 19%; p = 0.02) and occupational risk (28% vs. 10.5%; p < 0.0001) more frequently than did controls. Lockdown was the only protective measure against COVID-19 (50% vs. 70%; p < 0.0001). No differences were found in the use of systemic steroids, immunosuppressants or biologics between cases and controls. Cases were more often treated with 5-aminosalicylates (42% vs. 34%; p = 0.003). Having a moderate Charlson score (OR: 2.7; 95%CI: 1.3−5.9), occupational risk (OR: 2.9; 95%CI: 1.8−4.4) and the use of 5-aminosalicylates (OR: 1.7; 95%CI: 1.2−2.5) were factors for COVID-19. The strict lockdown was the only protective factor (OR: 0.1; 95%CI: 0.09−0.2). (4) Comorbidities and occupational exposure are the most relevant factors for COVID-19 in patients with IBD. The risk of COVID-19 seems not to be increased by immunosuppressants or biologics, with a potential effect of 5-aminosalicylates, which should be investigated further and interpreted with caution.

Mesalazine in Inflammatory Bowel Disease and COVID-19: Hospitalization and Adverse In-Hospital Outcomes Based on Nationwide Data

BACKGROUND

We assessed whether 5-aminosalicylic acid (5-ASA), as treatment for inflammatory bowel disease (IBD), was associated with an increase in hospitalization for coronavirus disease 2019 and adverse in-hospital outcomes.

METHODS

This was a Danish nationwide register study. The study population consisted of all patients with an IBD diagnosis between March 1, 2010, and March 1, 2020, and living in Denmark on March 1, 2020. Patients with IBD treated with 5-ASA (exposed) were compared with patients not receiving 5-ASA (unexposed).

RESULTS

We identified 60 242 patients with IBD; 15 635 (40.5%) with ulcerative colitis (UC) and 964 (4.5%) with Crohn's disease (CD) were exposed to 5-ASA. For patients with UC who were 5-ASA exposed, the hazard ratio of hospitalization was 1.18 (95% confidence interval, 0.79-1.78). In-hospital outcomes were not statistical significant from those not exposed to 5-ASA (median length of hospital stay 5.6 days vs 7.2 days), mechanical ventilation (0% vs 14%), continuous positive airway pressure (7.9% vs 9.4%), and in-hospital mortality (21.1% vs 17.2%). For patients with CD, the hazard ratio of hospitalization was 2.25 (95% confidence interval, 1.02-4.97). We found no statistically significant difference in length of hospital stay (7.1 days vs 3.9 days), mechanical ventilation (0% vs 1.8%), use of continuous positive airway pressure (0% vs 1.8%), or in-hospital mortality (0% vs 9%) between exposed and unexposed patients.

CONCLUSIONS

Patients with UC, treated with 5-ASA, had no increased risk of hospitalization for coronavirus disease 2019 or more adverse in-hospital outcomes. In patients with CD, 5-ASA may be associated with an increased risk of hospitalization but not with more adverse in-hospital outcomes.

Outcomes and Long-Term Effects of COVID-19 in Patients with Inflammatory Bowel Diseases - A Danish Prospective Population-Based Cohort Study with Individual-Level Data

BACKGROUND AND AIMS

The health consequences of coronavirus disease 2019 [COVID-19] among patients with ulcerative colitis [UC] and Crohn's disease [CD] remain largely unknown. We aimed to investigate the outcomes and long-term effects of COVID-19 in patients with UC or CD.

METHODS

We conducted a prospective, population-based study covering all Danish patients with CD or UC and confirmed COVID-19 between January 28, 2020 and April 1, 2021, through medical records and questionnaires.

RESULTS

All 319 patients with UC and 197 patients with CD who developed COVID-19 in Denmark were included in this study and compared with the Danish background population with COVID-19 [N = 230 087]. A significantly higher risk of COVID-19-related hospitalization was observed among patients with UC (N = 46 [14.4%], relative risk [RR] = 2.49 [95% confidence interval, CI, 1.91-3.26]) and CD (N = 24 [12.2%], RR = 2.11 [95% CI 1.45-3.07]) as compared with the background population (N = 13 306 [5.8%]). A similar pattern was observed for admission to intensive care (UC: N = 8 [2.51%], RR = 27.88 [95% CI 13.88-56.00]; CD: N = 3 [1.52%], RR = 16.92 [95% CI 5.46-52.46]). After a median of 5.1 months (interquartile range [IQR] 4.5-7.9), 58 [42.3%] and 39 [45.9%] patients with UC and CD, respectively, reported persisting symptoms which were independently associated with discontinuation of immunosuppressive therapies during COVID-19 (odds ratio [OR] = 1.50 [95% CI 1.07-10.22], p = 0.01) and severe COVID-19 (OR = 2.76 [95% CI 1.05-3.90], p = 0.04), but not with age or presence of comorbidities.

CONCLUSION

In this population-based study of 516 patients with IBD and COVID-19, 13.6% needed hospitalization and 2.1% required intensive care. Furthermore, sequelae were frequent, affecting 43.7% of COVID-19-infected patients. These findings might have implications for planning the healthcare of patients in the post-COVID-19 era.

Effect of inflammatory bowel disease and related medications on COVID-19 incidence, disease severity, and outcome: the Israeli experience

OBJECTIVES

The coronavirus disease 2019 (COVID-19) pandemic raised concerns among inflammatory bowel disease (IBD) patients fearing an increased risk of infection and poor outcomes. We aimed to evaluate the incidence of COVID-19 among IBD patients; its influence on disease severity and outcome; its relationship to medication use and how the pandemic affected IBD management.

METHODS

An anonymous questionnaire was posted online to members of the Israel Crohn's Disease and Ulcerative Colitis Foundation (November 2020-January 2021). The questionnaire addressed the course of IBD disease and COVID-19 infection over the past year.

RESULTS

Total 2152 IBD patients completed the questionnaire. Of which 104 (4.8%) had been infected with COVID-19, significantly lower than the 'expected' infected cases among the Israeli population (P = 0.033). The median age of participants was 39 years; 60.5% were female. Most patients (75.6%) had no comorbidities other than IBD. No correlation was found between IBD type or disease severity and COVID-19 infection. Most IBD patients reported mild COVID-19 disease, regardless of the type of IBD medications. Multivariable logistic regression analysis revealed that younger age, elevated BMI and diabetes were independent risk factors for COVID-19 infection. IBD treatment methods including 5-aminosalicylic acid, smoking and hypertension were protective factors. In total 25.2% of COVID-19 patients discontinued their IBD treatment, compared to 8.5% of non-COVID-19-infected patients. IBD flares were significantly higher in those who discontinued treatment (P < 0.001).

CONCLUSIONS

IBD patients do not have an increased risk for COVID-19, regardless of IBD activity or treatment. Patients should be encouraged to continue effective IBD therapy, including biologics and steroids, to minimize active IBD.

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.

Clinical Course of COVID-19 in Patients with Inflammatory Bowel Disease in Korea: a KASID Multicenter Study

In 2020, the novel coronavirus disease 2019 (COVID-19) began to spread worldwide and remains an ongoing medical challenge. This case series reports on the clinical features and characteristics of patients with inflammatory bowel disease (IBD) and confirmed COVID-19 infection. From February 2020 to March 2021, nine patients with IBD had confirmed COVID-19 across four hospitals in Korea. The median age at COVID-19 diagnosis was 42 years. Six patients were male, and seven patients had ulcerative colitis (UC). No patients required oxygen therapy, intensive care unit hospitalizations, or died. The most common symptom was fever, and gastrointestinal (GI) symptoms developed as diarrhea in five patients with UC. Oral steroids were used to combat UC aggravation in two patients. In this case series of nine IBD patients diagnosed with COVID-19 in Korea, the clinical presentation was predominately a mild respiratory tract infection. Most patients with UC developed new GI symptoms including diarrhea.

SARS-CoV-2 vaccination in patients with inflammatory bowel disease

BACKGROUND

The current COVID-19 pandemic, caused by Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2), has drastically impacted societies worldwide. Vaccination against SARS-CoV-2 is expected to play a key role in the management of this pandemic. Inflammatory conditions such as inflammatory bowel disease (IBD) often require chronic immunosuppression, which can influence vaccination decisions.

AIM

This review article aims to describe the most commonly available SARS-CoV-2 vaccination vectors globally, assess the potential benefits and concerns of vaccination in the setting of immunosuppression and provide medical practitioners with guidance regarding SARS-CoV-2 vaccination in patients with IBD.

METHODS

All published Phase 1/2 and/or Phase 3 and 4 studies of SARS-CoV-2 vaccinations were reviewed. IBD international society position papers, safety registry data and media releases from pharmaceutical companies as well as administrative and medicines regulatory bodies were included. General vaccine evidence and recommendations in immunosuppressed patients were reviewed for context. Society position papers regarding special populations, including immunosuppressed, pregnant and breast-feeding individuals were also evaluated. Literature was critically analysed and summarised.

RESULTS

Vaccination against SARS-CoV-2 is supported in all adult, non-pregnant individuals with IBD without contraindication. There is the potential that vaccine efficacy may be reduced in those who are immunosuppressed; however, medical therapies should not be withheld in order to undertake vaccination. SARS-CoV-2 vaccines are safe, but data specific to immunosuppressed patients remain limited.

CONCLUSIONS

SARS-CoV-2 vaccination is essential from both an individual patient and community perspective and should be encouraged in patients with IBD. Recommendations must be continually updated as real-world and trial-based evidence emerges.

Management of patients with Intestinal Bowel Disease and COVID-19: A review of current evidence and future perspectives

The COVID-19 pandemic has been a challenge for countries and health professionals worldwide. Viral entry by ACE-2 receptor and an excessive activation of the immune system are key to understand both incidence and severity of disease. Inflammatory Bowel Disease (IBD) represents a special condition associated with an inordinate response of the immune system to external agents. IBD treatments have been associated to an increased risk of bacterial and viral infections. This has raised the question of possible higher incidence and severity of COVID-19 infection in IBD patients. Several papers have been published during this year of pandemic to answer that question. Moreover, COVID-19 vaccination offers great promise in controlling infection in patients with IBD. Based on current evidence, patients with IBD do not have a higher incidence of COVID-19 than the general population, and they do not have worse disease evolution. Advanced age and presence of a greater number of comorbidities have been associated with worse outcomes, similar to the general population. Corticosteroids are associated to an increased risk of COVID-19 infection, higher hospitalization rate and higher risk of severe COVID-19. 5-ASA/Sulfasalazine and Thiopurines have a possible increased risk of severe COVID-19, although studies are lacking. On the other hand, Anti-TNF may have a possible protective effect. It is recommended to maintain the treatment. Anti-IL-12/23, anti-integrins and tofacitinib have results comparable to anti-TNF. Based on the efficacy, expert recommendations, and the absence of other evidence, it is recommended that patients with IBD be vaccinated.
