Does Reverse Causality Underlie the Temporal Relationship Between Depression and Crohn s Disease?

Summary

Studies suggest that there is a temporal relationship between depression and Crohn's disease (CD) activity. We evaluated the existence of reverse causality reflected in a possible bidirectional relationship between patient-reported CD activity and depression. To research this, we studied 3307 adult volunteers with a self-reported diagnosis of CD who completed a baseline survey that included demographics, CD activity, and depression. Crohn's disease status and depression were also measured 6 and 12 months after the first evaluation. The results of the hypothesis testing showed the most support for the hypothesis stating that depression is a stronger predictor of patient-reported CD activity. In conclusion, our findings suggest that CD patients' negative self-regard is clinically important to understanding change in patient reports of their CD activity. Gastroenterologists should screen for affective-cognitive symptoms of depression in CD patients. Evaluation and treatment of depression may improve the course of CD.

A Diet Low in Red and Processed Meat Does Not Reduce Rate of Crohn s Disease Flares

Summary

Diet may be an important factor in the development and progression of IBD. A previous study demonstrated that patients with ulcerative colitis were more likely to flare with increased consumption of red and processed meats. We sought to examine whether increased consumption of red and processed meats was associated with Crohn's disease (CD) flares. To do this, adults with CD were recruited from IBD Partners. Patients who were in remission were randomly assigned to groups that consumed a minimum of 2 servings/week of red or processed meat (118 patients) or not more than 1 serving per month (96 patients) for 49 weeks. The primar y outcome was relapse of CD, defined as increase in short Crohn's Disease Activity Index or a need for surgery or a need for new medication. During the trial, patients in the high-meat group reported compliance with eating 2 or more servings of red or processed meat during 98.5% of weeks compared to 18.8% of weeks for the low-meat group. In an analysis of data from the FACES trial, we found that among patients with CD in remission, amount of red and processed meat consumption was not associated with risk of flare.

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.

The impact of ostomy on quality of life and functional status of Crohn's disease patients within CCFA Partners

Summary

Patients with Crohn's disease, or CD, may require surgery during the course of their disease. This can result in the need to create a permanent or a temporary ostomy. Ostomy is the term used to describe the surgically created connection between the intestine and the abdominal wall. It allows for the evacuation of the fecal matter through the abdominal wall. The potential need for an ostomy is a major concern for many patients with inflammatory bowel disease as it may impact their daily function and quality of life. Within the CCFA Partners network, we evaluated the characteristics of CD patients who had an ostomy for at least 6 months. We also looked at how ostomy impacts their daily function and quality of life. A total of 4733 patients were included, of these, 402 reported an ostomy for at least 6 months. Patients with ostomy were more likely to be in clinical remission compared to those with no ostomy. Also, only half the patients with ostomy were receiving specific IBD therapies. Having an ostomy did not impact the quality of life or sexual function (interest and satisfaction) of CD patients. Additionally, there was no association between having an ostomy and anxiety, depression, or sleep disturbances. However, having an ostomy was associated with increased pain interference, fatigue and lower social satisfaction. It was also associated with higher rated of narcotic use. Appropriate counseling before and after surgery can help improving social satisfaction for patients with ostomy. Further studies are needed to determine the nature of pain and fatigue in this population.

Evaluation of Gastrointestinal Patient Reported Outcomes Measurement Information System (GI-PROMIS) Symptom Scales in Patients with Crohn's Disease in CCFA Partners

Summary

Patient reported outcomes (PROs) are important measures of how well treatment works in Crohn's disease (CD). PROs are symptoms reported directly by patients, rather than tests like colonoscopies or blood work. The PRO Measurement Information System (PROMIS) is a new scale for measuring PROs for physical, mental and social health. The results can be compared to those from people that don't have IBD. A gastrointestinal (GI) PROMIS scale was recently developed. The GI scales were not studied in large numbers of Crohn's patients, but were studied in people all across the United States. We studied these questions in 1839 people with Crohn's disease in CCFA Partners. Most (75%) were women. People with Crohn's disease reported more fatigue, anxiety and pain compared to people without Crohn's disease. People with Crohn's disease reported less reflux, problems swallowing and constipation than people without Crohn's disease. Other GI symptoms for people with Crohn's disease were similar to those reported by people without Crohn's disease. Compared to people in remission, people with active CD reported worse symptoms on the GI-PROMIS scales for all symptoms except problems swallowing and constipation. Those with a worse quality of life, as measured by the Short IBD Questionnaire (SIBDQ), reported worse symptoms on the GI-PROMIS scales all symptoms. People who reported more nausea, diarrhea, gas/bloat and abdominal pain reported more psychosocial symptoms on the PROMIS scales. In summary, those with worse symptoms on the GI-PROMIS scales scored worse disease activity scales, quality of life scales and more symptoms of depression and anxiety. These scales could be important ways 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.

Association Between Affective-Cognitive Symptoms of Depression and Exacerbation of Crohn's Disease

Summary

Depression is common among patients with Crohn's disease (CD). In this study, we wanted to understand if CD patients in remission who reported symptoms of depression were more likely to experience worsened CD symptoms later in time. To answer this question we looked at responses to CCFA Partners survey questions submitted by more than 2,000 CD patients about negative mood (I felt depressed), negative beliefs about the self (I felt worthless, I felt hopeless), and decreased life engagement/negativity (I felt hopeless) during the past seven days. Twelve months later, we asked about the severity of their CD activity using a standard CD questionnaire about diarrhea, pain, and well-being. We found that symptoms of depression predicted CD activity a year later. In other words, CD patients who were depressed were more likely to have CD symptoms a year later than those who were not depressed.

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.

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.
