Summary Background Since the start of the COVID‐19 pandemic, there have been many scientific reports regarding gastrointestinal manifestations. Several reports indicate the possibility of viral shedding via faeces and the possibility of faecal‐oral transmission. Aims To critically assess the clinical relevance of testing stool samples and anal swabs and provide an overview of the potential faecal‐oral transmission of SARS‐CoV‐2. Methods A systematic literature search with MeSH terms was performed, scrutinising the Embase database, Google scholar, MEDLINE database through PubMed and The Cochrane Library, including articles from December 2019 until July 7 2020. Data were subsequently analysed with descriptive statistics. Results Ninety‐five studies were included in the qualitative analysis. 934/2149 (43%) patients tested positive for SARS‐CoV‐2 in stool samples or anal swabs, with positive test results up to 70 days after symptom onset. A meta‐analysis executed with studies of at least 10 patients revealed a pooled positive proportion of 51.8% (95% CI 43.8 ‐ 59.7%). Positive faecal samples of 282/443 patients (64%) remained positive for SARS‐CoV‐2 for a mean of 12.5 days, up to 33 days maximum, after respiratory samples became negative for SARS‐CoV‐2. Viable SARS‐CoV‐2 was found in 6/17 (35%) patients in whom this was specifically investigated. Conclusions Viral shedding of SARS‐CoV‐2 in stool samples occurs in a substantial proportion of patients, making faecal‐oral transmission plausible. Furthermore, detection in stool samples or anal swabs can persist long after negative respiratory testing. Therefore, stool sample or anal swab testing should be (re)considered in relation to decisions for isolating or discharging a patient.
Background Work productivity (WP) loss includes absence from work (absenteeism) and productivity loss while working (presenteeism), which leads to high indirect costs in inflammatory bowel disease (IBD). Prior health economic analyses predominantly focused on absenteeism. Here we focus on presenteeism and assess predictors of WP loss, fatigue, and reduced health-related quality of life (HRQL). Methods Employed IBD patients completed the following surveys: Work Productivity and Activity Impairment, Multidimensional Fatigue Inventory, and Short Inflammatory Bowel Disease Questionnaire. Predictors were assessed using uni- and multivariable regression analyses. Annual costs were calculated using percentages of WP loss, hourly wages, and contract hours. Results Out of 1590 invited patients, 768 (48%) responded and 510 (32%) were included. Absenteeism, presenteeism, and overall WP loss were reported by 94 (18%), 257 (50%), and 269 (53%) patients, respectively, resulting in mean (SD) annual costs of €1738 (5505), €5478 (8629), and €6597 (9987), respectively. Disease activity and active perianal disease were predictors of WP loss (odds ratio [OR] = 6.6; 95% confidence interval [CI], 3.6-12.1); OR = 3.7; 95% CI, 1.5-8.7). Disease activity and arthralgia were associated with fatigue (OR = 3.6; 95% CI, 1.9-6.8; OR = 1.8; 95% CI, 1.0-3.3)) and reduced HRQL (OR = 10.3; 95% CI, 5.9-17.9; OR = 2.3; 95 % CI, 1.4-3.8). Fatigue was the main reason for absenteeism (56%) and presenteeism (70%). Fatigue and reduced HRQL led to increased costs compared with absence of fatigue and normal HRQL (mean difference = €6630; 95% CI, €4977–€8283, P < 0.01; mean difference = €9575; 95% CI, €7767–€11,384, P < 0.01). Conclusions Disease activity and disease burden lead to WP loss in approximately half of the employed IBD population, driving indirect costs. Fatigue is the most important reason for WP loss.
SUMMARY BackgroundTen percent of patients with autoimmune hepatitis (AIH) are nonresponsive or intolerant to thiopurine therapy. A skewed metabolism, leading to the preferential generation of (hepato)toxic thiopurine metabolites (6-MMPs) instead of the metabolic active 6-tioguanine (thioguanine) nucleotides (6-TGNs), may explain this unfavourable outcome. Co-administration of allopurinol to low-dose thiopurine therapy may effectively revert this deviant metabolism, as has been shown in inflammatory bowel disease.
Summary Background Few data are available on the effects of age and comorbidity on treatment outcomes of vedolizumab and ustekinumab in inflammatory bowel disease (IBD). Aims To evaluate the association between age and comorbidity with safety and effectiveness outcomes of vedolizumab and ustekinumab in IBD. Methods IBD patients initiating vedolizumab or ustekinumab in regular care were enrolled prospectively. Comorbidity prevalence was assessed using the Charlson Comorbidity Index (CCI). Association between age and CCI, both continuously assessed, with safety outcomes (any infection, hospitalisation, adverse events) during treatment, and effectiveness outcomes (clinical response and remission, corticosteroid‐free remission, clinical remission combined with biochemical remission) after 52 weeks of treatment were evaluated. Multivariable logistic regression was used to adjust for confounders. Results We included 203 vedolizumab‐ and 207 ustekinumab‐treated IBD patients, mean age 42.2 (SD 16.0) and 41.6 (SD 14.4). Median treatment duration 54.0 (IQR 19.9‐104.0) and 48.4 (IQR 24.4‐55.1) weeks, median follow‐up time 104.0 (IQR 103.1‐104.0) and 52.0 weeks (IQR 49.3‐100.4). On vedolizumab, CCI associated independently with any infection (OR 1.387, 95% CI 1.022‐1.883, P = 0.036) and hospitalisation (OR 1.586, 95% CI 1.127‐2.231, P = 0.008). On ustekinumab, CCI associated independently with hospitalisation (OR 1.621, 95% CI 1.034‐2.541, P = 0.035). CCI was not associated with effectiveness, and age was not associated with any outcomes. Conclusions Comorbidity ‐ but not age ‐ is associated with an increased risk of hospitalisations on either treatment, and with any infection on vedolizumab. This underlines the importance of comorbidity assessment and safety monitoring of IBD patients.
The use of corticosteroids in autoimmune hepatitis is an established therapy. To avoid the possible serious side effects of corticosteroids, immunosuppression with azathioprine is often warranted. Azathioprine, a purine analogue, is frequently used to taper or replace corticosteroids. However, approximately 10% of the patients are intolerant to azathioprine. Alternative therapies using mycophenolate, tacrolimus, budesonide, cyclosporine and 6-mercaptopurine have been studied, with variable results. The use of 6-thioguanine, an agent more directly leading to the down-stream active metabolites of azathioprine (6-thioguanine nucleotides) in inflammatory bowel disease patients intolerant to azathioprine or 6-mercaptopurine showed conflicting results. We report three patients with autoimmune hepatitis who could not tolerate azathioprine but tolerated 6-thioguanine 0.3 milligram per kilogram daily well. All three patients improved clinically. Therapeutic drug monitoring was performed. The prospective evaluation of 6-thioguanine as a possible immunosuppressive drug in autoimmune hepatitis patients is warranted.
Background: Inflammatory Bowel Disease (IBD) can have considerable effects on employment outcomes because of its disabling character. Goals: We aimed to investigate the impact of IBD in the workplace and to better understand the need for accommodations and adaptations. Study: Between November 2017 and March 2018, IBD patients were recruited from outpatient clinics in Christchurch Hospital, New Zealand. The survey assessed employment, the need for workplace accommodations and the difficulty arranging it, insurance, and disability using the item-reduced Inflammatory Bowel Disease Disability Index for self-report (IBD-DI-SR). Data were analyzed using descriptive statistics and multivariate logistic regression modeling. Results: One hundred twenty-three patients were included (response rate 64%), 112 of whom reported that they experienced symptoms while working (60% female, 71% Crohn’s disease, mean age 41.9 years). Ninety-one percent needed at least 1 workplace accommodation when symptoms were most severe. Almost half of the patients who needed an accommodation had difficulty arranging it. The most needed accommodations were time to go to medical appointments (71%) and easy access to a suitable toilet (71%). Being female, having less effective medication, and being distressed were associated with the need for 2 or more accommodations, difficulty in arranging accommodations, and not asking for needed accommodation. Conclusions: Many IBD patients need accommodations at work while symptomatic in order to overcome workplace disability, which can be difficult to arrange. Improved resources are needed to inform employees and employers about the disease, the possibilities for workplace accommodations, and practical strategies to request them.
Objectives Although bowel symptoms are often predominant, inflammatory bowel disease (IBD) patients can have several oral manifestations. The aim of this study was to investigate the prevalence of dental caries and periodontal disease in patients with Crohn’s disease (CD) and ulcerative colitis (UC) compared to an age and gender-matched control group of patients without IBD. Material and methods The DMFT (Decayed, Missing, Filled Teeth) scores and the DPSI (Dutch Periodontal Screening Index) of 229 IBD patients were retrieved from the electronic health record patient database axiUm at the Academic Centre for Dentistry Amsterdam (ACTA) and were compared to the DMFT scores and DPSI from age and gender-matched non-IBD patients from the same database. Results The total DMFT index was significantly higher in the IBD group compared to the control group. When CD and UC were analyzed separately, a statistically significant increased DMFT index was observed in CD patients but not in UC patients. The DPSI did not differ significantly between the IBD and non-IBD groups for each of the sextants. However, in every sextant, IBD patients were more frequently edentulous compared to the control patients. Conclusion CD patients have significantly more dental health problems compared to a control group. Periodontal disease did not differ significantly between IBD and non-IBD groups as determined by the DPSI. Clinical relevance It is important that IBD patients and physicians are instructed about the correlation between their disease and oral health problems. Strict oral hygiene and preventive dental care such as more frequent checkups should be emphasized by dental clinicians.
SummaryBackgroundAzathioprine (AZA) and mercaptopurine (MP) are the cornerstone of steroid‐sparing strategies in autoimmune hepatitis (AIH). Up to 20% of patients do not tolerate or respond to these regimens.AimTo evaluate retrospectively the tolerability and efficacy of tioguanine (thioguanine) (TG) therapy in selected patients with AIH and AIH variant syndromes.MethodsRecords of 52 patients who received TG therapy were retrieved from nine hospitals in the Netherlands. Indications for TG treatment were intolerable side effects on AZA or MP (n = 38), insufficient response (n = 11) or first‐line treatment (n = 3). Treatment efficacy was defined as normalisation of serum aminotransferases and serum immunoglobulin G.ResultsNo serious adverse events occurred in patients treated with TG during a median follow‐up of 18 months (range 1‐194). Treatment was well tolerated in 41 patients (79%), whereas four had tolerable (8%) and seven (13%) intolerable side effects. Thirty‐eight patients were treated with TG after intolerable side effects on AZA or MP; 29 patients continued TG therapy of whom 24 (83%) achieved complete biochemical remission, four (14%) had incomplete and one (3%) had no response; nine discontinued treatment. Seven of 11 patients with insufficient response to AZA or MP were responsive to TG, three with complete and four with incomplete biochemical remission; four discontinued due to intolerance (n = 2) and non‐response (n = 2). TG was effective in all AIH patients as first‐line maintenance treatment.ConclusionIn our retrospective review of TG therapy in selected patients with AIH or AIH variants who previously failed on AZA or MP, TG appeared tolerable with biochemical efficacy.
