Posttraumatic Stress in Patients With Inflammatory Bowel Disease: Prevalence and Relationships to Patient-Reported Outcomes

Summary

Post-traumatic stress (PTS) is a chronic psychological reaction to an event where the person experiences actual or perceived threat to life or bodily harm. PTS symptoms include nightmares, flashbacks, irritability or low mood, feeling keyed up or on edge, and avoiding situations that trigger trauma memories.

Before this study, only one study on PTS and IBD, with 140 patients, had been conducted in the US. In the previous study, a much higher than expected proportion of patients (32%) reported moderate to severe symptoms of PTS. Because of the nature of IBD and its treatment, researchers aimed to see if there was a similar proportion of PTS in a larger patient sample through IBD Partners and to see how PTS symptoms are related to patient outcomes.

Researchers measured PTS symptoms in a large study of 797 participants using a standard symptom questionnaire and collected other data from IBD Partners including IBD disease activity, hospitalizations, surgeries, and quality of life. Researchers then looked at relationships between PTS symptom severity and each of these important IBD metrics. As expected, PTS was associated with more severe IBD, increased hospitalizations and surgeries, and increased anxiety, depression, fatigue, and pain impact in daily life. Researchers also found women, and racial and ethnic minorities were disproportionally affected by PTS.

Pregnancy and Neonatal Outcomes After Fetal Exposure to Biologics and Thiopurines Among Women With Inflammatory Bowel Disease

Summary

Researchers included nearly 1500 women with Crohn's disease and ulcerative colitis who became pregnant. To better understand pregnancy outcomes, those on medications like biologics were compared to those not on these medications. Children were followed for the first year of life.

Importantly, being on biologics and thiopurine medications did not increase any pregnancy or neonatal complications. In fact, higher disease activity of IBD was associated with complications like miscarriage and preterm birth. Researchers concluded that medications should be continued throughout pregnancy to control IBD symptoms and reduce pregnancy-related complications.

Trends and Characteristics of Clinical Trials Participation for Inflammatory Bowel Disease in the United States: A Report From IBD Partners

Summary

Between 2011 and 2018, participation in randomized controlled trials (RCTs) for inflammatory bowel disease declined while available RCTs in-creased. Younger patients, patients in community settings, and patients with milder disease were underrepresented in RCTs. Nonparticipants had disease activity failing remission criteria, highlighting the role of RCT participation.

Impact of Obesity on Disease Activity andPatient-Reported Outcomes Measurement InformationSystem (PROMIS) in Inflammatory Bowel Diseases

Summary

The rate of diagnoses has increased for both obesity and IBD, and some research suggests that obesity may play a part in the development of IBD. About 15-40% of patients with IBD are obese, which is defined as having a body mass index (BMI) of 30 or higher. However, there has been little research on how obesity might affect outcomes in patients with IBD. In this study of nearly 7300 patients with IBD, we found that about one in 5 patients with IBD were obese. Obese patients were more likely to have active symptoms related to IBD, as compared to patients with normal BMI. Over a period of 12-18 months, we obs erved that obese patients with active disease were significantly less likely to achieve remission. Similarly, among patients in remission at baseline, obese patients were 2-3 times more likely to relapse on follow-up, as compared to patients with normal BMI. Obese patients with IBD were more likely to have anxiety, depression, fatigue, and experience pain. They were also less satisfied with their ability to participate in social roles. These effects were seen in patients with both ulcerative colitis and Crohn's disease. Future studies to find out whether treating obesity may improve outcomes in patients with IBD are needed.

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.

Paternal Disease Activity Is Associated With Difficulty inConception Among Men With Inflammatory Bowel Diseases

Summary

IBD commonly affects men and women during their reproductive ages. Because of this, researchers are interested in knowing how the disease affects fertility and pregnancy. Much research on the impact of IBD on fertility and pregnancy has focused on women, but for this study, researchers focused on men. They wanted to know how men's IBD and their use of IBD medication affect reproductive outcomes. The study results showed that men who received a diagnosis of IBD before trying to conceive were more likely to have difficulty conceiving than men who developed IBD after conceiving. However, these fi ndings were noted only in those with recently active disease within the past 6 months. Men with IBD who were in long-term remission were similar to the rates prior to development of IBD. Exposure to any of the medications for treating IBD was not associated with congenital anomalies, low birth weight or preterm births.

Inflammatory Bowel Diseases Can Adversely Impact Domains of Sexual Function Such as Satisfaction with Sex Life

Summary

Little research has been done exploring how inflammatory bowel disease (IBD) affects sexual health. In this study, investigators asked a large group of IBD patients to complete a 6-question online survey. The questions asked about sexual interest and satisfaction. Researchers found that these IBD patients had similar levels of sexual interest as the general population, but they had lower sexual satisfaction and lower quality of life as it related to their IBD. Older age, disease activity, depression, anxiety, and pain were associated with these findings. Exploring these sexual health topics during clinical encounters can help improve IBD quality of life.

Body Image Dissatisfaction in Pediatric Patients with Inflammatory Bowel Diseases

Summary

Children and teenagers with Inflammatory Bowel Disease (IBD) are at increased risk of being unhappy with their body image. This study aimed to learn more about how common body image dissatisfaction (or "BID") is among these children and teenagers and to see if we could point to any risk factors for having BID. A total of 664 participants in the IBD Partners Kids & Teens study, ages 9-18, completed an online survey about anxiety, depression, disease activity, and quality of life. We found that about 3% of participants met the criteria for having BID by selecting the answer choices "I look awful" or "I look bad" when asked about their appearance. Young patients with BID tended to have worse disease, to be taking steroids, to be female, and to be diagnosed at an older age. These participants were also much more anxious and depressed than those who were satisfied with their appearance. Pediatric patients with BID should discuss these concerns with their physicians and healthcare teams.

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.

Obesity Is Associated with Worse Disease Activity in Patients with Inflammatory Bowel Diseases: an Internet Based Cohort Study

Summary

More than 1/3 of adults in the US are obese and the rates of obesity are increasing. However, relatively little is known about the prevalence of obesity in patients with inflammatory bowel disease (IBD) or the impact of obesity on IBD disease activity. In this study, we reviewed patients in the CCFA Partners database to better understand these issues. We found that approximately 30% of IBD patients were overweight and an additional 20% were obese. Patients who were overweight or obese were less likely to have their IBD in remission at baseline. We also found that patients who were obese (but not overweight patients) were more likely to have a relapse of their IBD within 6-12 months compared to normal weight patients. In summary, obesity appears to be relatively common amongst patients with IBD and may be a risk factor for worsened disease.

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.

Menopause and Hormone Replacement Therapy in Women with Inflammatory Bowel Diseases in CCFA Partners

Summary

Women with inflammatory bowel disease, or IBD, frequently experience changes in abdominal symptoms (e.g. bowel frequency and pain) in relation to the different stages of the menstrual cycle. This may be related to the hormonal changes during the various stages of the cycle. Menopause is the state when the menstrual cycles and associated hormonal fluctuations stop permanently. This can occur naturally in relation to age or can be secondary to surgery or medical therapy that impact the reproductive organs. The impact of menopause on disease activity of patients with IBD is unknown. We assessed the disease characteristics of menopausal women within the CCFA Partners network. We also evaluated the impact of menopause and hormone replacement therapy, or HRT, on disease activity. A total of 2252 women were included in this study. Of these, 799 indicated that they had gone through menopause. The majority of post-menopausal women reported natural menopause with an average age of 50 in both Crohn's disease and ulcerative colitis patients. About half the post-menopausal women indicated a current or prior use of HRT. The post-menopausal state was associated with increased disease activity in both Crohn's disease and ulcerative colitis patients. This association was more prominent for women at age = 45 compared to those older than 45 years. Interestingly, the use of HRT did not impact disease activity at any age. Those findings suggest that the cessation of hormonal fluctuation in post-menopausal women as well as the age play role in predicting disease activity in women with IBD.

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.

Perceptions of Patients with Inflammatory Bowel Diseases on Biobanking

Summary

A biobank is a collection of samples from patients (including spit, stool or blood). Biobanks are very important for understanding risk factors for developing disease or for severity of disease. We wanted to understand more about why patients with inflammatory bowel disease (IBD) would or would not participate in a biobank. We first did a series of interviews over the phone with patients who were participating in the CCFA Partners study. This helped us to understand the important concerns about biobanks and develop a survey for use in CCFA Partners. We then sent a survey to over 800 people with IBD in CCFA Partners. We did a total of 26 phone interviews. Patients doing the interviews told us that they had concerns about how samples would be collected/stored; who would be allowed access; whether these samples would be used for other things (not only research); and whether this would affect whether they could get life insurance. Most people were not that worried about using the blood for genetic studies. People thought that that biobanks were important for research, that they might lead to a cure; that by donating they would be helping others or family members with IBD; and hoped that they might personally benefit, although most understood that they likely would not. These themes aided in the development of a survey instrument to assess perceptions of biobanking. A total of 476 people initially finished the survey. Almost 40% said that they would 'definitely yes' donate samples, 56.0% would 'probably yes' donate, 5.1% 'probably no' and 0.7% 'definitely no'. There were no factors that made someone more likely to donate (reported donation rates were not different for Crohn's disease (CD) versus ulcerative colitis (UC), remission versus active disease, or education level. People were most willing to donate spit, followed by blood and lastly stool. Knowing these important thoughts on sample donation/biobanks will help researchers to develop consents for IBD biobanks and design educational materials on biobanks for IBD A biobank is a collection of biological samples, such as saliva, blood, and stool, from individuals with a common condition such as inflammatory bowel disease (IBD). Biobanks are important for understanding risk factors for developing disease or for severity of disease. We wanted to learn more about IBD patients' understanding of and willingness to participate in a biobank. We first did 26 phone interviews with patient volunteers participating in the CCFA Partners study. Those interviews helped us better understand concerns related to biobanks. Patients doing the interviews told us that they had concerns about how samples would be collected/stored, who would be allowed access, whether these samples would be used for anything other than research, and whether participation in a biobank would affect life insurance eligibility. Most patients were not that worried about using blood for genetic studies. Participants thought biobanks were important for research, that they might lead to a cure, that by donating they would be helping others or family members with IBD, and hoped that they might personally benefit. These results from the phone interviews were used to develop an online survey instrument to assess perceptions of biobanking. In a larger sample, a total of 1,007 people with IBD completed the online survey. Almost 40% said they would 'definitely' donate samples, 56.4% would ‘probably’ donate, 3.6% ‘probably not’, and 0.6% 'definitely not'. There were no differences in willingness to donate specimens based on disease type (Crohn's vs. ulcerative colitis) or on disease activity (in remission vs. currently active disease). People were most willing to donate saliva specimens, followed by blood and lastly stool samples. Knowing these important attitudes and beliefs about sample donations and biobanks will help researchers develop consents and educational materials related to biobanks that will encourage wider involvement.

Sleep Disturbance and Risk of Active Disease in Patients With Crohn's Disease and Ulcerative Colitis

Summary

People with inflammatory bowel disease (IBD), like Crohn's disease and ulcerative colitis, tend to have poor quality of sleep. In this study of over 3000 people with IBD, those with more disease activity, depression, female gender, a history of smoking, or those currently taking corticosteroids or narcotics were more likely to have sleep disturbance. Of people with Crohn's disease who were in remission at the beginning of the study, those with sleep disturbance were twice as likely to have a flare in 6 months. No effect was seen for ulcerative colitis. These results suggest that sleep is important for maintaining remission in IBD.

Risk Factors for Depression in the Elderly Inflammatory Bowel Disease Population

Summary

Depression is common among patients with inflammatory bowel disease, or IBD. This study showed that as many as 1 in 4 elderly patients with IBD may suffer from depression. Depressed elderly patients with IBD were more likely to have more severe disease activity. They were also less likely to take their medication correctly all of the time.
