ABSTRACT
Background Inflammatory Bowel Disease(IBD) and Irritable Bowel Syndrome(IBS) are gastrointestinal disorders which differ in pathophysiology and management. The use of immunomodulatory drugs brings concerns which increased during the pandemic. Similarly, patients with IBS may have concerns about the effect of infection and vaccine on their wellbeing. The aim of this study was to assess for any differences in swabbing, vaccine uptake, COVID-19 infection, hospitalisation rates and outcomes in patients with IBD on immunomodulatory treatment and patients with IBS. Methods Patients were recruited through the local database (March, 2020 – August, 2021). All IBD patients had a histological diagnosis while IBS patients were diagnosed according to ROME IV criteria. All patients were offered vaccination. Apart from demographic data the following was collected: number of COVID-19 swabs taken, vaccination rates, type of vaccine administered, infection secondary to COVID-19, hospitalization and outcomes. Results Overall, 250 IBD patients (43.6% female) and, 250 patients with IBS (78.4% female) were recruited. The mean patient age in the IBS cohort was, 40.6 years (SD ±, 11.99) whilst the mean patient age in the IBD cohort was, 40.7 years (SD±15.7). Patients with IBD underwent significantly more COVID-19 swab tests (n=759) than patients with IBS (n=615) (p =0.02). Patients with IBD were having the following biological therapy:, 62.8% Infliximab, 24.8% Adalimumab, 10% Vedolizumab and, 2.4% Ustekinumab. There was no significant difference in COVID-19 infection rate between the IBS cohort (8.8%;n=22 patients;, 2 patients not vaccinated) and the IBD cohort (6.4%;n=16 patients;, 3 patients not vaccinated)(p=0.3). The vaccine uptake rate was similar (IBD:, 91.2%, IBS: 90%). Table, 1 demonstrates the type of vaccine administered to both cohorts. In the IBS cohort, 1 patient was admitted to hospital in view of symptomatic hypoxaemia. The patient was treated with oxygen and dexamethasone, but did not require ventilatory support. Within the IBD cohort, 3 patients requiring admission for IBD related treatment, tested positive asymptomatically on pre-admission COVID-19 screening. All had an uneventful outcome.Table 1CohortPfizerAstraZenecaJohnson&JohnsonModernaIBD43%54%1%2%IBS57%31%7%5% Conclusion This study demonstrates that vaccine uptake, Covid-19 infection rates and outcomes were similar in patients with IBS and IBD patients on immunosuppressive therapy. However, IBD patients underwent significantly more swabbing than patients with IBS and this was generally due to patient concern of acquiring Covid-19 while being on immunosuppresive medications. This added psychological burden may further impact patients’ psychological state and thus their quality of life.
ABSTRACT
Since the novel coronavirus disease 2019 (COVID-19) has been declared a pandemic, the possibility of recurrence of the disease after recovery has become a debated issue. We report a case of an 84-years-old male patient who was admitted to our hospital for dyspnea and fever. Lab and clinical workout showed that he had COVID-19. After a full recovery of symptoms and a double negative nasopharyngeal swab of severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) by realtime polymerase chain reaction assay, he was discharged from the hospital. One month later, he developed dyspnea and fever again with lung involvement. Surprisingly, the nasopharyngeal swab of SARS-CoV-2 was positive. Since he denied contacts with confirmed or suspected cases of COVID-19, he probably experienced a reactivation of a persistent infection. The failed eradication of the virus could depend on both virus' escape mechanisms and dysfunctional immune response. Further studies are needed to confirm the hypothesis of viral reactivation and identify signs of an incomplete clearance.
