Background and Aims: Inflammatory bowel diseases (IBD) patients management has been challenging during the ongoing coronavirus disease 2019 (COVID-19) pandemic, due to lockdowns, limitation of access to medical facilities and new recommendations regarding patient management. The implications of the COVID-19 pandemic on IBD patients’ management were assessed in our Tertiary Gastroenterology Center in Bucharest, Romania. Methods: Medical records of IBD patients admitted between 15th of March and 15th of August 2020 were retrospectively reviewed and compared to a control cohort of consecutive IBD patients admitted to our unit during the corresponding period of 2019. Results: There was a highly significant shift towards one-day hospitalization during the referral period in 2020 for IBD cases (91% in 2020 vs 82.2% in 2019, p=0.0001). There was no statistically significant difference between the distribution of patient’s gender, IBD phenotype or newly diagnosed IBD cases. A significantly lower proportion of admitted patients received 5-aminosalicylic acid (29% vs 41.2%, p=0.0001), whereas a substantially higher number of patients were prescribed biological therapy in 2020 in comparison to the corresponding 2019-time frame (79.5% vs 57.9%, p<0.0001). The distribution of the biological agent used was significantly different in 2019 in comparison to the 2020 period mainly due to the increase in vedolizumab prescription in 2020 (p<0.0001). During the study period in 2020, seven IBD patients (1.7%) were diagnosed with severe acute respiratory syndrome coronavirus 2 (SARS-Cov2) infection, all of them with mild symptoms without impact on the IBD course. Conclusions: The COVID-19 pandemic led to reorganizing medical care, limiting the hospital admissions in favor of severe IBD cases, favoring telemedicine for mild disease and optimization of treatment for moderate to severe IBD with an increased use of biologicals aimed to maximize the risk/benefit ratio. Incidence of SARS-Cov2 infection during the first wave of COVID-19 infection in our study group was 1.7% and did not adversely impact the IBD disease course.
Background In spite of prolonged disease remission of IBD patients, induced by the new biological molecules, a significant number of them suffer from persistent debilitating symptoms with major impact on the quality of life. Frequently, these symptoms are due to post-inflammatory motility changes and misinterpreted as functional disorders. Our aim is to identify and characterize the anorectal motility dysfunction in IBD patients. Methods We are conducting an ongoing prospective study started in August 2019, which includes the IBD patients admitted in a Tertiary Gastroenterology Centre in Bucharest, with specific symptoms (anorectal pain, incontinence, difficult defecation). We perform high resolution anorectal manometry using Sandhill Scientific systems, the parameters being analysed using InSIGHT software. The manometric testing comprise measurements of anorectal pressure at rest, during squeeze, simulated evacuation, rectoanal inhibitory reflex (RAIR) and rectal sensory testing, in compliance with International Anorectal Physiology Working Group protocol. Results We studied 21 patients (12 patients with Ulcerative Colitis and 9 patients with Crohn’s Disease, 15 females and 6 males, mean age 40 (±11.43) years. Only 23.1% (5 patients) had rectal active involvement. Symptoms were reported by 81.0% (17) patients: pain (57.1%), anal incontinence (94.1%), difficult evacuation (29.4%), urgency (64.7%) and intolerance of rectal therapies (35.3%); rectal inflammation was not correlated with the presence of symptoms in our study group (p= 0.53). Modified manometric parameters were found in 81.0% patients and were associated with previous pelvic surgical interventions (p<0.05); although, the latter does not seem to increase the risk of incontinence (p=0.33). In 61.9% cases the manometric measurements correlated with the symptoms. 85% of the patients with passive incontinence presented lower resting pressure and 57.1% of those with active incontinence were found with lower squeeze pressures. Changes compatible with dyssynergia were detected in 61.9% of the cases. Sensory testing revealed alterations in 46.2% of patients, and RAIR was negative in 33.3% of the cases. Conclusion There is a considerable number of patients with anorectal motility changes. Therefore, pelvic floor investigation is an essential tool in the management of IBD patients with anorectal symptoms.
Background Bowel ultrasonography (BUS) is an accurate imaging method for detecting and monitoring inflammatory bowel disease (IBD) patients. This technique is recommended by current guidelines besides gold standard endoscopic assessment in managing IBD patients. Several BUS characteristics strongly correlate with biological markers of inflammation suggesting that these tests could be used in monitoring IBD patients but is yet unknown how these features predict the patient’s evolution. Methods Our study included 95 consecutive IBD patients (24 diagnosed with ulcerative colitis, 71 with Crohn’s disease) with both active and inactive disease at presentation. IBD diagnosis was established endoscopically and histologically. Patients with superimposed infection (viral or bacterial) and patients that had solely rectal involvement of the disease were excluded. BUS was conducted at baseline by one skilled examiner blinded to biological data. Biological markers were evaluated at baseline and all cases were prospectively followed-up for the need of therapy escalation during the next 6 months. The following BUS characteristics were registered in every patient: bowel wall thickness, alteration of wall structure, thickened mucosa or submucosa, presence of hyperechoic spots in the mucosal wall, irregularity of the external wall, Doppler signal, presence of mesenteric hypertrophy, presence of lymph nodes, and an overall assessment of the examination. No special preparation was needed before BUS. Results Of all the monitored sonographic features, the following characteristics correlated with the need of increasing treatment in the following 6 months: bowel wall thickness, altered structure of the wall, hypertrophic mucosa, Doppler signal, and the overall assessment of the examination (p < 0.001). The presence of the lymph nodes, hyperechoic spots in the mucosa, thickened submucosa and the irregularity of the external wall were not statistically significant correlated with the need for treatment escalation. The strongest correlation with the need for increasing treatment was documented for a mean bowel wall thickness > 5 mm and for Doppler signal presence in the bowel wall (p < 0.00001). In the multivariate analysis, Doppler signal presence was the only independent predictor for the need treatment escalation during a 6-month follow-up. Conclusion The most important sonographic features with an impact on therapeutic decision making in IBD patients are: bowel wall thickness, Doppler signal, altered stratification of the wall and mesenteric hypertrophy. In our analysis, the Doppler signal was the only independent predictor for the need for step-up therapy.
A limited role of cytokine storm and fibrogenesis in COVID-19 related liver injury To the Editor, Symptomatic transaminases elevations are common in coronavirus disease 2019 (COVID-19). In approximately 23% of all patients elevated transaminases are seen. COVID-19 related liver injury may be caused by primary liver injury but also as collateral damage related to drug-induced-liver-injury, hypoxia, and preexisting liver disease [1]. Hepatitis may aggravate disease severity, and lead to mortality. In this context, it is important to understand the impetus for liver injury [2].We performed a multimodality approach to dissect the contributing factors to liver injury in a well-defined cohort of COVID-19 patients. The aim was to explore inflammatory and fibrosis biomarkers and their relation to pre-existing liver disease. We examined a cohort of 25 patients (mean age 57.9 years, male 72%, median body mass index 27.3 kg/m 2) who were hospitalized in 2020 in the Radboudumc, Nijmegen, The Netherlands. All presented with COVID-19 infection established on basis of a positive polymerase chain reaction Letters to the Editor
