Psychological Factors Associated With Adherence to Oral Treatment in Ulcerative Colitis

Summary

Self-determination theory (SDT) is a theory of motivation that presumes that humans have three basic psychological needs-autonomy, competence, and relatedness. Each of these needs impacts one's motivation to adhere to a medical regimen. For example, this might mean choosing to take prescribed medications (autonomy), having the mastery to take the medication correctly (competence), and having quality relationships to support those skills (relatedness).

Past research has examined whether SDT can be applied to a variety of health issues, such as asthma, diabetes, and quitting smoking. However, no studies to date have examined this theory in people with ulcerative colitis (UC). Dr. Dasharathy used data from IBD Partners to better understand adherence to oral medications in people with UC, and how this relates to stress, motivation, competence, and relationships with health care providers.

Urgency and its Association with Quality of Life and Clinical Outcomes in Ulcerative Colitis Patients

Summary

Urgency, which is the immediate need to defecate, is common in IBD. In this study, we evaluated the relationship between urgency in ulcerative colitis patients and outcomes like quality of life and hospitalizations.

We studied 632 patients with UC. Urgency, described as "hurry," "immediately," and "incontinence," was associated with many factors like social isolation, depression, anxiety, and fatigue. It was also associated with increased risk of hospitalization, steroids, and surgery.

These findings support using urgency as an important quality of life outcome to be studied in clinical trials.

Evaluation of Gastrointestinal Patient Reported Outcomes Measurement Information System (GI-PROMIS) Symptom Scales in Subjects With Inflammatory Bowel Diseases

Summary

Patient reported outcomes (PROs) are important measures of how well treatments work in inflammatory bowel disease (IBD). PROs are symptoms reported directly by patients, rather than tests like colonoscopies or blood work. The PRO Measurement Information System (PROMIS) is a scale for measuring PROs for physical, mental, and social health. A gastrointestinal (GI) PROMIS scale was recently developed based on responses from people across the United States. The GI PROMIS scale includes questions about eight common GI symptoms: gas, reflux, diarrhea, soilage, constipation, belly pain, nausea and vomiting, and difficulty swallowing. We studied these questions in 2,378 people with Crohn's disease (CD) and 1,455 people with ulcerative colitis (UC) in CCFA Partners. About half of the participants reported being in remission. Compared to participants in remission, those with active CD reported worse symptoms on the GI-PROMIS scale for all symptoms. The same was true for participants with active UC with the exception of difficulty swallowing. Participants with worse quality of life reported worse symptoms on the GI-PROMIS scale for all symptoms. Participants with more diarrhea, belly pain, and gas reported poorer mental and social PROs. In summary, participants who reported worse GI-PROMIS symptoms also reported worse qualify of life, disease activity, and mental and social outcomes. These results suggest that the GI-PROMIS scales could be an important way to measure symptoms in the future.

Variation in Care of Inflammatory Bowel Diseases Patients in CCFA Partners:Role of Gastroenterologist Practice Setting in Disease Outcomes and QualityProcess Measures

Summary

Variation in care of patients with Crohn's disease (CD) and ulcerative colitis (UC) has been used as a marker for quality differences. We studied whether important aspects of IBD patients' care in CCFA Partners varied based on where their GI doctor was in practice. We compared patients who saw an academic (university) GI physician, a private practice GI physician, or other GI physician (such as a Veteran's Affairs physician). The study included about 12,000 IBD patients. Almost 95% reported visiting a GI provider at least once a year: about 74% saw a private practice physician, 15% academic, and 11% other. Those patients with CD seen by academic physicians were younger, has completed higher education, used less mesalamine medications, and used more biologics and immunomodulators. They were more likely to be in remission, were more likely to get a flu shot, smoked less, and were less likely to be on steroids when compared to private or other physicians. Patients with UC seen by academic providers were younger, had more hospitalizations and surgery, with greater biologic and immunomodulator use. There was no difference in steroid use, and no differences in any of the other measures like remission rates, flu shot, quality of life. In summary, there was much more variation in CD care as compared to UC care, with improved outcomes for CD patients seen by academic providers. Studying why this is the case, could help us to improve the quality of care delivered to all IBD patients.

Role of Nonsteroidal Anti-Inflammatory Drugs in Exacerbations of Inflammatory Bowel Disease

Summary

Nonsteroidal anti-inflammatory drugs (NSAIDs, medications such as Advil, ibuprofen, naproxen, etc.) may cause GI inflammation in patients with inflammatory bowel disease (IBD). IBD patients are often told to avoid these medications. We looked at patients in CCFA Partners in who were in remission (with few to no symptoms) and asked about regular NSAID use. We then looked at whether they flared 6 months later. A total of 791 patients were included, of these, 40.6% reported ever using NSAIDS at baseline. Patients with Crohn's disease (CD) who regularly used NSAIDS (at least 5 times/monthly) had a 65% increased risk of later flare. No effect of regular NSAID use was seen for ulcerative colitis (UC). Those with CD who used acetaminophen (Tylenol) also had a 72% increased risk of later flare. Lower doses of NSAIDs had no association with flare. Therefore, regular NSAID use or acetaminophen use may increase the risk of flare in CD, but not UC. This may be related to effects of the medications. It is also possible that those people with IBD who require pain medications at baseline may not be in as full a remission, which may increase the risk of later flare.

Exercise Decreases Risk of Future Active Disease in Patients with Inflammatory Bowel Disease in Remission

Summary

Little is known about how exercise impacts disease activity in patients with inflammatory bowel disease (IBD). This study explored the relationship between exercise level and disease activity in a large group of patients with IBD in remission. A total of 1,857 patients from the CCFA Partners cohort participated by answering online questions about their exercise level and disease activity at the beginning of the study (in remission) and then again after six-months. We found that participants with Crohn's disease who reported higher levels of exercise at the beginning of the study were significantly less likely to report active disease six-months later. We also found this association among participants with ulcerative colitis (UC) and indeterminate colitis (IC), but the results were not significant. Results of this study suggest that for patients with Crohn's disease (and possibly for patients with UC and IC) who are in remission, higher levels of exercise may reduce the risk of developing active disease in the short-term.

Development of CCFA Partners Kids & Teens: an Internet-Based Cohort of Pediatric IBD

Summary

After the successful launch of CCFA Partners for adult patients with inflammatory bowel disease, the kids and teens component (CCFA Partners Kids & Teens) started in 2013. In partnership with the Crohn's and Colitis Foundation of America (CCFA), children <18 years of age were asked to join the internet-based study through email invitations and promotion on social media sites. After informed consent, the children and their parents completed surveys asking questions about their disease, their medications and other patient reported outcomes (such as quality of life, fatigue, sleep, peer relations, mood, etc). In the first month, 419 children joined. The average age was 13, with about 1/2 being female and about 3/4 having Crohn's disease (CD). Common medications used by patients with CD were biologics, thiopurines (6mp or azathioprine) or mesalamine-based medications (Pentasa, Lialda, Apriso, etc). The most common medication for patients with ulcerative colitis (UC) was mesalamine-based medications. Most of the CD patients were in remission and most UC patients had mild disease. Children who had active disease had more depression and anxiety. Following this group of children over time will help us to learn a great deal about living with IBD as a child, and will allow us to follow these children into adulthood to learn even more about the disease itself, the impact of medications, and how symptoms change over time.
