Inflammatory Bowel Diseases

Inflammatory Bowel Diseases refer to a group of chronic, relapsing conditions affecting the gastrointestinal tract.
This umbrella term encompasses disorders such as Crohn's Disease and Ulcerative Colitis, which are characterized by inflammation, ulceration, and impaired intestinal function.
Symptoms may include abdominal pain, diarrhea, rectal bleeding, and weight loss.
The exact causes are not fully understood, but are thought to involve a complex interplay of genetic, immunologic, and environmental factors.
Effective management often requires a multidisciplinary approach, including medication, dietary modifications, and in some cases, surgical intervention.
Ongoing research aims to better understand the pathophysiology and develop more targeted, individualized therapies to improve quality of life for those affected by these debilitating conditions.

Data for this study were acquired from a recently completed placebo-controlled randomized trial of rosiglitazone for mild to moderately active ulcerative colitis (clinicaltrials.gov #NCT00065065) which has been described in greater detail previously.7 (link) The trial used a slight modification of the Mayo score to assess disease activity (Table 1). Specifically, the bleeding component as described in the Mayo index was modified such that a score of 3 required both visible blood in 50% or more of bowel movements and at least some bowel movements with blood alone.
The study included 105 patients with mild to moderately active disease defined as a total DAI score of 4 to 10, inclusively. Patients were randomized in a 1:1 ratio to receive either rosiglitazone 4 mg or placebo twice daily for 12 weeks. Disease activity was measured at randomization and every four weeks thereafter until week 12, however lower endoscopy was only completed at week 0 and week 12, such that only a partial Mayo score (9 point scale that excludes the endoscopic appearance of the mucosa) could be calculated at the interim visits. In the very early accrual period of the study, a follow-up visit was included at week 2. Without knowledge of the response rates in either arm, the Data and Safety Monitoring Board (DSMB) requested that the week 2 follow-up evaluation be eliminated with the hopes of minimizing the placebo response rate and maximizing recruitment and retention.6 (link), 8 (link), 9 (link) Eighteen patients completed the week 2 follow-up visit.
During the course of the study, patients could be treated with other conventional medications used to treat active ulcerative colitis including mesalamine, oral corticosteroids, immunomodulators, or topical therapies (mesalamine or corticosteroids) at stable doses. Use of corticosteroids at doses greater than 20mg per day of prednisone or the equivalent was an exclusion criterion. Steroid tapering was not permitted during the study.
In anticipation of this sub-study, at each visit we also included questions about change in disease activity compared to the previous visit and compared to the randomization visit on a global seven-point scale (Table 2). The choices included much better, moderately better, a little better, unchanged, a little worse, moderately worse, and much worse. Patients also graded their current disease activity at each visit on a 6 point Likert scale – perfect, very good (minimal symptoms), good (only mild symptoms), moderately active, moderately severe, or severe. Data on quality of life were measured with the Inflammatory Bowel Disease Questionnaire (IBDQ) authored by Dr. Jan Irvine under license from McMaster University, Hamilton, Canada.10 (link)

In this study, we revised and expanded our earlier PheWAS phenotype categorization to a total of 1,645 phenotypes identified from International Classification of Disease, Ninth revision, Clinical Modification (ICD9) codes. (Our initial PheWAS phenotype categorization included 744 phenotypes9 (link).) The ICD9 coding system is divided into four components: diseases, signs and symptoms (“three digit” codes, 001–999), external causes of injury (“E” codes), procedures (“two digit” codes 00.0–99.9) and supplemental classifications (“V” codes). The prior PheWAS code groupings included only diseases, signs and symptoms (three digit) ICD9 codes9 (link). We revised and expanded the PheWAS phenotypes by (i) adding V codes (commonly used to record personal histories of given diseases) and E codes (which refer to external causes of injury) to the PheWAS code mapping, (ii) redesigning the code system to be hierarchical, such that one phenotype could be a parent of another subphenotype (e.g., cardiac arrhythmias is a parent of atrial fibrillation, atrial flutter and other arrhythmias), and (iii) including more granular phenotypes into the coding system (e.g., “type 1 diabetes with ketoacidosis”). Creation of hierarchical phenotypes included creation of phenotypes not present in the ICD9 billing hierarchy, such as “inflammatory bowel disease” as the parent phenotype for “Crohn’s disease” and “ulcerative colitis.” In this process, we were guided by the hierarchical organization of the Clinical Classifications Software (CCS) produced by the Agency for Healthcare Research and Quality42 (link); the 2011 version of the CCS contains 727 phenotypes. The resulting PheWAS code group currently contains 1,645 phenotypes, 1,358 of which had at least 25 cases (a prevalence of 0.18% in our data set) in the eMERGE cohort, our threshold for these analyses. The current version of the PheWAS codes, with ICD9 mappings and control groups, is available from http://knowledgemap.mc.vanderbilt.edu/research/content/phewas.

The Clinical IBD data was obtained from the Inflammatory Bowel Disease Multiomics Database [15 (link)]. A large cohort of IBD patients were included for this study. The stool samples of CD (n = 266), UC (n = 144), and non-IBD (n = 135) were collected. The extraction and purification steps have already been described previously [29 (link)]. The quality control (QC, n = 59) samples were also included. All clinical information from the samples is summarized in Table S2. The data format conversion and initial parameters were identical to the NIST dilution series above. The TICs of the data are shown in Figure S4. Parameter optimization was performed using four QC samples from each group randomly selected from the whole batch. The optimized parameters are provided in Table S1. The data analysis was finished with the whole MetaboAnalystR 3.0 workflow. Functional analysis was performed by integration with Mummichog2 for the comparisons between different groups (cutoff of p value 2.0 × 10−6).

Ten specialists in inflammatory bowel disease (IBD, the authors) graded videos of flexible sigmoidoscopy according to their own practice, in the absence of clinical information. Twenty-four representative videos were selected to represent the widest range of UC activity, guided by the Mayo Clinic score (by PK and BRY) from a library of 670 videos recorded in a standard manner during clinical trials for the treatment of moderately active UC6 (link) (EUDRACT 2006-001310-32). Within each Mayo Clinic score stratum, consecutive videos were reviewed by one of the co-authors for image quality. Satisfactory quality recordings (sharp image, sufficient bowel preparation) were selected. Videos from fibreoptic endoscopes were discarded. Sixteen videos represented the complete range of severity; 24 videos enabled choice from additional videos in the mid-range of severity, most likely to be affected by interobserver variation. Each investigator was randomly assigned 16 of the 24 videos in randomised order using a set of Latin squares: a core set of eight videos that all investigators evaluated (two for each Baron score) and eight of 16 non-core videos, This kept the number of evaluations by each investigator in the 2–3 h session to a manageable number (16), while still having a common core set (8) and a broad overall pool of videos (24). Investigators were explicitly advised not to apply the Baron index themselves, to avoid biasing their overall assessment of severity in relation to this index. To assess potential scoring differences based on the length of the video,11 (link) each investigator had two pairs that were shortened from 10–15 min to approximately 5 min, giving a total of 18 videos for each investigator to view. Descriptors of endoscopic severity were selected from previous studies.3 (link)

13 (link) Investigators recorded the presence or absence of 11 descriptors. Overall severity was assessed on a visual analogue scale (VAS, between 0=completely normal and 100=worst ever seen).
To substantiate variability in endoscopic assessment, the level of the Baron index derived from the assessments by investigators was compared with the level assigned by the central reader in the original trial.7 The precise wording of definitions and video clips illustrating anchor points on three-, four- or five-point Likert scales of severity for each descriptor, were subsequently agreed by consensus during a video teleconference between investigators (table 1).

We also include a brief analysis of microbiome data from a study of inflammatory bowel diseases (IBDs) [28] (link). This comprised faecal samples from 78 individuals where the V5-6 region of the 16S rRNA gene was pyrosequenced using 454. 35 samples were from healthy individuals, 12 from individuals with colonic Crohn's disease (CCD), 15 from individuals exhibiting ileal Crohn's disease (ICD), and 16 from individuals with ulcerative colitis (UC). We processed the data as above. This gave a total of 134,276 reads with individual samples varying in size from 394 to 3,258 with a median of 1,710 reads. 93 separate genera were observed in these samples with a genera diversity per sample that varied from 8 to 33 with a median of 22.

Clinical outcomes were collected for all patients who provided a viable sample, by requesting copies of examination reports from participating sites every month. All diagnoses were determined by reviewing endoscopy, radiology, and histology reports, clinic letters, and urgent referral forms provided by the participating sites. Patient and clinical data included symptoms, reasons for the referral, medical history, and sociodemographic factors. All diagnoses were verified by medical members of the central research team.
All neoplastic bowel polyps, either adenomatous polyps or sessile serrated polyps, were identified and were given a risk of either ‘low’, ‘intermediate’, or ‘high’ depending on their size and frequency; contemporary UK and European guidelines were used in this study23 ,24 (link), with low risk defined as 1–2 adenomas less than 10 mm, intermediate risk as 3–4 small adenomas less than 10 mm or one adenoma 10 mm or more, and high risk as five or more adenomas less than 10 mm or three or more adenomas with at least one 10 mm or more.
Non-neoplastic polyps, such as hyperplastic, inflammatory, or pseudopolyps, were classified separately. Patients with a risk score for their polyps at first, second, or third examinations had their cumulative number and/or highest risk polyp taken as their final score. Remaining bowel pathology was classified as one of CRC, inflammatory bowel disease (colitis/proctitis), diverticulosis, haemorrhoids, normal examination, or procedure stopped/incomplete. Patients with concurrent polyps and CRC were classified as CRC and not included in the analysis, as our target group for this study was those without CRC in whom we could potentially identify polyps and plan for removal before they could progress to CRC.

The outcome of interest in this study was newly diagnosed autoimmune diseases after the index dates. In Taiwan, people with several autoimmune diseases can apply for catastrophic illness certification to receive a copayment exemption from the NHI program, and all the applications are reviewed by rheumatologists. These autoimmune diseases, including SLE, systemic sclerosis, Sjögren’s syndrome, inflammatory myopathy, rheumatoid arthritis, Behcet’s syndrome, systemic vasculitis, type I diabetes mellitus, multiple sclerosis, myasthenia gravis, inflammatory bowel diseases, autoimmune hemolytic anemia, and pemphigus, were identified from the Registry for Catastrophic Illness, and thus the diagnoses should be valid. For autoimmune diseases that did not fulfill the requirements to be considered catastrophic illnesses in Taiwan, including ankylosing spondylitis, post-infectious arthritis, uveitis, psoriasis, autoimmune thyroid disease, primary adrenocortical insufficiency, Guillain–Barré syndrome, autoimmune encephalomyelitis, and celiac disease, one hospital admission or at least three outpatient visits with relevant ICD-9-CM or ICD-10-CM codes were regarded as the confirmed diagnosis (S1 Table). The follow-up of study participants started on the index dates and continued until the confirmation of study outcomes, death, or August 31, 2018, whichever occurred first.
