Endoscopy

Endoscopy is a medical procedure that allows healthcare providers to visually examine the interior of the body using a specialized instrument called an endoscope.
This minimally invasive technique is widely used in the diagnosis and treatment of various conditions, particularly those affecting the digestive, respiratory, and urinary systems.
Endoscopic procedures can range from simple examinations to complex interventions, providing valuable insights into the underlying causes of symptoms and enabling targeted therapies.
By utilizing advanced imaging technologies, endoscojes enable healthcare professionals to navigate the body's intricate structures, detect abnormalities, and perform delicate procedures with precision.
This versatile tool has become an indispensable part of modern medicine, empowering clinicians to deliver more effective and personalized care to patients.
Reasearch protocols play a vital role in ensuring the accuracy and reproducibility of endoscopic findings, underscoreing the importance of tools like PubCompare.ai that can streamline the identification and comparison of protocols from a vast array of literature sources.

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)

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 used data from two prospective cohort studies, the Nurses’ Health Study (NHS, involving 121,700 women who were enrolled in 1976) and the Health Professionals Follow-up Study (HPFS, involving 51,500 men who were enrolled in 1986).22 (link),23 (link) Every 2 years, participants were sent follow-up questionnaires to update information on lifestyle factors and to identify newly diagnosed cancers and other diseases. The National Death Index was used to ascertain deaths of study participants. The cause of death was assigned by study physicians. Paraffin-embedded tissue blocks were collected from hospitals where participants with colorectal cancer had undergone colorectal resection or endoscopic biopsy (for preoperatively treated rectal cancer). Tumor-tissue data, information on aspirin use, and survival data were available for 1097 patients with colorectal cancer that was diagnosed before July 1, 2006. Among these patients, we used data from 964 patients for whom information about the presence or absence of PIK3CA mutation, based on analysis of tumor tissue, was available. Patients were followed until death or January 2011, whichever came first.
Written informed consent was obtained from all study participants. Tissue collection and analyses were approved by the human subjects committees at the Harvard School of Public Health and Brigham and Women's Hospital. The last two authors were responsible for the study concept and design. All authors acquired, analyzed, and interpreted the data. The first two authors and the last two authors take responsibility for the integrity of the data and the accuracy of the data analysis and vouch for the fidelity of the study to the protocol.

As a proof of concept, the patient population of this study is patients that (1) have moderate to severe ulcerative colitis, regardless of extent, and (2) have had an insufficient response to a previous treatment, e.g., a conventional therapy (e.g., 5-ASA, corticosteroid, and/or immunosuppressant) or a FDA-approved treatment. In this placebo-controlled eight-week study, patients are randomized. All patient undergo a colonoscopy at the start of the study (baseline) and at week 8. Patients enrolled in the study are assessed for clinical status of disease by stool frequency, rectal bleeding, abdominal pain, physician's global assessment, and biomarker levels such as fecal calprotectin and hsCRP. The primary endpoint is a shift in endoscopy scores from Baseline to Week 8. Secondary and exploratory endpoints include safety and tolerability, change in rectal bleeding score, change in abdominal pain score, change in stool frequency, change in partial Mayo score, change in Mayo score, proportion of subjects achieving endoscopy remission, proportion of subjects achieving clinical remission, change in histology score, change in biomarkers of disease such as fecal calprotectin and hsCRP, level of adalimumab in the blood/tissue/stool, change in cytokine levels (e.g., TNFα, IL-6) in the blood and tissue.

FIG. 72 describes an exemplary process of what would occur in clinical practice, and when, where, and how the ingestible device will be used. Briefly, a patient displays symptoms of ulcerative colitis, including but not limited to: diarrhea, bloody stool, abdominal pain, high c-reactive protein (CRP), and/or high fecal calprotectin. A patient may or may not have undergone a colonoscopy with diagnosis of ulcerative colitis at this time. The patient's primary care physician refers the patient. The patient undergoes a colonoscopy with a biopsy, CT scan, and/or MRI. Based on this testing, the patient is diagnosed with ulcerative colitis. Most patients are diagnosed with ulcerative colitis by colonoscopy with biopsy. The severity based on clinical symptoms and endoscopic appearance, and the extent, based on the area of involvement on colonoscopy with or without CT/MRI is documented. Treatment is determined based on diagnosis, severity and extent.

For example, treatment for a patient that is diagnosed with ulcerative colitis is an ingestible device programmed to release a single bolus of a therapeutic agent, e.g., 40 mg adalimumab, in the cecum or proximal to the cecum. Prior to administration of the treatment, the patient is fasted overnight and is allowed to drink clear fluids. Four hours after swallowing the ingestible device, the patient can resume a normal diet. An ingestible device is swallowed at the same time each day. The ingestible device is not recovered.

In some embodiments, there may be two different ingestible devices: one including an induction dose (first 8 to 12 weeks) and a different ingestible device including a different dose or a different dosing interval.

In some examples, the ingestible device can include a mapping tool, which can be used after 8 to 12 weeks of induction therapy, to assess the response status (e.g., based on one or more of the following: drug level, drug antibody level, biomarker level, and mucosal healing status). Depending on the response status determined by the mapping tool, a subject may continue to receive an induction regimen or maintenance regimen of adalimumab.

In different clinical studies, the patients may be diagnosed with Crohn's disease and the ingestible devices (including adalimumab) can be programmed to release adalimumab in the cecum, or in both the cecum and transverse colon.

In different clinical studies, the patients may be diagnosed with illeocolonic Crohn's disease and the ingestible devices (including adalimumab) can be programmed to release adalimumab in the late jejunum or in the jejunum and transverse colon.

We included all adults (≥ 18 years) with an inpatient or ambulatory surgery performed between April 1 2005 and February 28 2019 in Alberta, Canada. Surgeries were identified using the Canadian Classification of Health Interventions (CCI) coding [14 ], which is a standardized coding system for procedures. Radiologic or non-surgical procedures were excluded (e.g., endoscopy, hemodialysis catheter insertion, arteriovenous [AV] fistulogram, etc.). Further, we included only those with preoperative kidney failure, defined as an eGFR < 15 mL/min/1.73m2 or receiving hemodialysis or peritoneal dialysis for at least 90 days as an outpatient before the index surgical procedure. For non-dialysis participants, at least two outpatient measures of serum creatinine between 7–365 days were necessary prior to surgery to avoid misclassification of people with preoperative acute kidney injury, per a validated algorithm [15 (link)]. We estimated eGFR using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation without including the Black race coefficient [16 (link)]. We excluded people that left Alberta within 30 days of their surgery, and those without available demographic data.

In all centres, patients undergoing FMT treatment were registered prospectively. Data about IBD outcome and long-term follow-up were in part collected retrospectively (Supplemental Figure 1).
Data collection was performed by each centre using files of the FMT services and hospital records for the patients. If possible, patients were contacted directly. The following baseline characteristics were collected: age, gender, and the use of PPIs. The following data about the CDI were collected: number of episodes; diagnostics by polymerase chain reaction or toxin enzyme immunoassay; and information about previous treatment with metronidazole, vancomycin, fidaxomicin, or bezlotoxumab. Severe CDI was defined as leukocytes ⩾15 × 109/L and/or a 50% increase in creatinine at baseline.17 (link) FMT data included the pre-treatment regimen (antibiotics, bowel lavage), total number of FMTs needed per patient, the route of administration of FMT, and the total amount of faeces (grams) used for preparation of the suspensions or capsules that were administered per patient. Data about clinical recurrence and microbiological testing for CDI after FMT were collected at 8–12 weeks after FMT. Long-term follow-up data of CDI recurrence were included if available.
For IBD, information was collected about the diagnosis according to the Montreal classification and the disease duration. Previous and current IBD medication at the moment of FMT and the use of immunosuppressive medication (including corticosteroids and budesonide, immunomodulators and biologicals) was assessed. Both at baseline and 8 weeks after FMT, the presence of an IBD flare was based on information from the treating physician and/or endoscopic scores. In case of a concomitant flare, remission-induction therapy was defined as the use of prednisolone or budesonide at the moment of FMT, or recently initiated antitumor necrosis factor (TNF) treatment (⩽2 months before FMT). Also haemoglobin (mmol/l) and C-reactive protein (mg/l) in the blood and the calprotectin (µg/g) in the faeces were collected at baseline and after 8 weeks.
The long-term follow-up period per patient was calculated from the date of FMT up to 31 December 2020. Long-term follow-up data included information about possibly occurring events and if yes, the number of days after FMT it occurred. Possible occurring events, collected via patient recall or from hospital records, were as follows: a recurrence of CDI, the development of an IBD flare, general infection and antibiotic use, hospital admission, colectomy, and occurrence of death.
