Association Between Vulvovaginal Discomfort and Activity of Inflammatory Bowel Diseases

Summary

Inflammatory bowel diseases (IBD) affect 200-400 people per 100,000 in the United States, about half of whom are women. Our goal was to research how common it is for women with IBD to experience vulvovaginal symptoms. For this study, we recruited women more than 18 years old with IBD (1250) who agreed to complete an online survey that asks questions about the presence and severity of vulvar or vaginal itch, burn, or irritation, vaginal discharge or dryness, and vulvovaginal pain. The survey collected information on background information and a history of their IBD activity history. Women with and withou t symptoms were compared for analyses. For the results, we found a total of 512 women reported at least 1 moderate-severe vulvovaginal symptom. All vulvovaginal symptoms except vaginal dryness were more common in women with active IBD and vulvovaginal discomfort frequently or always decreased interest in sex or ability to have sex. In conclusion, we found that women with more active IBD have increased prevalence of vulvovaginal discomfort, compared to women in remission. These symptoms affect sexual health.

Changes in Patient-Reported Outcomes With Vedolizumab Therapy in Patients With Inflammatory Bowel Diseases (IBD): Results From the IBD Partners Patient Powered Research Network

Summary

We studied whether patients starting Entyvio® (vedolizumab), who had previously used an anti-TNF biologic, such as Remicade® (infliximab) or Humira® (adalimumab), responded differently than people who had not used one of these therapies. We studied 380 patients with Crohn's disease and ulcerative colitis in the IBD Partners cohort who were starting vedolizumab. We found that patients who had not previously used an anti-TNF biologic had higher remission rates and improved quality of life.

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.

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.

Profiles of Patients Who Use Marijuana for Inflammatory Bowel Disease

Summary

Marijuana is legal in a number of states for indications that include inflammatory bowel diseases (IBD), and patients are interested in its potential benefits. For this study, we aimed to describe the legal use of marijuana in individuals with IBD in the USA who participate within the IBD Partners Patient Network. Approximately 2400 participants who lived in states where prescription or recreational marijuana was legal, were offered the chance to complete a survey on marijuana use and IBD symptoms. Surveys were completed by 1666 participants (71%). Within the surveyed group, 234 participants lived where both medical and recreational marijuana is legal and 49 mentioned recreational marijuana use specifically for IBD. Most of the users reported positive benefits, but users also reported more depression, anxiety, pain, and lower social satisfaction than non-users. Overall, we found that few IBD patients consulted their medical doctors about marijuana use or used prescription marijuana. Where recreational marijuana was available, usage rates were higher. Users reported benefits but also more I BD symptoms, depression, anxiety, and pain. Marijuana use may be higher in patients with IBD symptoms not well treated by traditional medical treatments.

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.

Infertility Care Among Men and Women With Inflammatory Bowel Diseases in the CCFA Partners Cohort

Summary

We studied how often women and men with inflammatory bowel disease (IBD) seek care for infertility (problems getting pregnant). We also looked at reasons why individuals had trouble getting pregnant. A total of 12.5% of women in CCFA Partners went to see a doctor for problems getting pregnant. This was a little higher in women with Crohn's disease (14.1%) than in women with ulcerative colitis (9.5%). Risk factors for needing help getting pregnant were: prior GI surgery and older age. The most common cause of fertility problems in women was blocked fallopian tubes. For men, 8.7% needed help with fertility. Age was a risk factor. The most common cause of fertility problems was a problem with their female partner. Nearly 80% of women and men who went to the doctor for fertility problems were able to get pregnant. These rates of pregnancy with fertility treatment are similar to those of people without IBD.

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.

Hormonal Contraception Use is Common Among Patients with Inflammatory Bowel Diseases and an Elevated Risk of Deep Vein Thrombosis

Summary

People with inflammatory bowel disease (IBD) have an increased risk of blood clots due to having inflammation. Other risk factors can include things like smoking, using steroids, and being overweight. Most forms of hormonal contraception (birth control pills) have estrogen which can also increase clotting risk. We studied whether people with IBD that had risk factors for clotting were also put on birth control pills. This could be an opportunity for prevention (as other birth control options are available that do not increase clotting risk). Over 3000 women with IBD completed surveys asking about birth control methods and other risk factors for clotting. Birth control pills were used in over 30% of women with IBD. Women with risk factors for clotting (smoking, steroids, obesity) still had the same rates of birth control pill use as those without these risk factors. Based on this study, it is important for GI doctors to ask patients about birth control use and find out whether they also have other risk factors for a blood clot. By changing the form of contraception, this could prevent a complication of a blood clot 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.

Keep or Destroy? Attitudes of Patients With Inflammatory Bowel Diseases on Biospecimen Handling at Biobank Closure

Summary

A biobank is a collection of samples from patients (including spit, stool or blood). Biobanks are important for understanding risk factors for developing disease or for severity of disease. The purpose of this study was to understand how patients with inflammatory bowel diseases (IBD) feel about the continued use of their samples after the biobank has closed. A total of 26 CCFA Partners members participated in a phone interview about the risks and benefits of their samples being used for research, and the results of these conversations were used to create a survey. The survey included three primary themes: 1) degree to which samples remain an individual's property after donation; 2) samples are a good that can be sold; and 3) the belief that results from sample analysis could lead to discrimination. About 1,000 CCFA Partners participants completed the survey online. Most participants expressed the desire to know what would happen to their samples and genetic information if the biobank closed. Most were comfortable with the samples and genetic information being destroyed. Most were also comfortable donating their samples and genetic information to IBD research. Most participants were not comfortable with selling their samples and genetic information after the biobank closes. We learned that it is important for researchers to create a plan for samples if the biobank closes and to communicate this plan to the participant at the beginning of the study.

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.

Evaluation of the Patient Reported Outcomes Measurement Information System in a Large Cohort of Patients with Inflammatory Bowel Diseases

Summary

Patient-reported outcomes, or PROs, can give useful information to doctors and researchers about patient health. In a study of over 7000 patients with inflammatory bowel disease, or IBD, PROs showed that IBD patients had more anxiety, depression, fatigue and sleep disturbance, and less social satisfaction than the general population. Using corticosteroids made all of the outcomes worse. These results showed that IBD patients, like patients with other chronic illnesses, were lower functioning than the general population.

Prevalence of a Gluten-free Diet and Improvement of Clinical Symptoms in Patients with Inflammatory Bowel Diseases

Summary

Patients with celiac disease (an autoimmune disorder where eating gluten can damage the small intestine) benefit from a gluten free diet (GFD). Few data are available to tell us if patients with inflammatory bowel diseases (IBD) may also benefit from this diet. Individuals with GI symptoms such as bloating, abdominal pain, diarrhea, fatigue and nausea can have non-celiac gluten sensitivity, for which a GFD can be beneficial. Non-celiac gluten sensitivity can also co-exist with IBD. We therefore asked patients enrolled in CCFA Partners whether they have ever tried a gluten free diet (GFD), whether they followed this diet closely, and whether it helped with any symptoms. A total of 1647 people took the survey on GFD. A total of 314 (19.1%) reported that they had ever tried a GFD and 135 (8.1%) were currently following the diet. Overall, 206/314 (65.6%) trying a GFD reported improvement in any GI symptom while on this diet. Over a 1/3 of people (38.3%) felt that they experienced fewer or less severe flares while on the diet. Improvements in clinical symptoms were reported for bloating (56.5%), diarrhea (42.6%), abdominal pain (41.5%), fatigue (27.5%), and nausea (26.3%) while on a GFD. Fatigue was significantly improved with excellent adherence to the diet. Because many patients had improved symptoms on the GFD, it is possible that patients with IBD could suffer from non-celiac gluten sensitivity. Fewer people who felt better on a GFD were taking biologics medications, suggesting that flare symptoms in those with more severe disease may not respond to a GFD. Future studies are needed to understand the benefits of this diet in IBD patients, and the mechanism of improvement with this dietary intervention.

Sexual Interest and Satisfaction in an Internet Cohort of Patients with Inflammatory Bowel Diseases

Summary

In a survey of over 2500 patients with inflammatory bowel disease, 80% said that their disease symptoms affected their sexual interest and satisfaction. In general, women, patients with disease around their rectum and patients with more active disease had less sexual interest and satisfaction. Half of patients with ostomies said that their ostomy affected their sexual satisfaction.

Quality of Life in Patients with Inflammatory Bowel Diseases within the CCFA Partners Cohort

Summary

In a survey of over 7000 patient with Crohn's disease or ulcerative colitis, patients had about the same quality of life for both diseases. Patients with severe ulcerative colitis had low quality of life, but quality of life returned to around average when patients had surgery to remove their colon and replace it with an internal pouch. These results show that status of inflammatory bowel disease can be an important factor in quality of life.

Medication Adherence in Patients with Inflammatory Bowel Diseases within the CCFA Partners Cohort

Summary

In a survey of over 7000 patients with inflammatory bowel disease, or IBD, more than half of all patients got a low score on medication adherence questions, which means that most patients are not taking their IBD medications correctly all of the time. In general, people felt better when they had a high medication adherence score. The researchers recommend educating patients to improve medication adherence.

Status of Prevention in Patients with Inflammatory Bowel Diseases within the CCFA Partners Cohort

Summary

Patients with inflammatory bowel disease, or IBD, may be more likely to develop weak bones, infections like influenza and tuberculosis and certain cancers of the skin, cervix and colon, depending on the type of medications they use. Fortunately, there are simple activities that can prevent these from occurring. In a survey of over 7000 patients with IBD, only about half had a bone density scan or took calcium or vitamin D supplements to promote bone health. Only 40% reported having a skin exam and 16% reported always wearing sunscreen to prevent skin cancer. Less than two thirds had an influenza (flu) vaccine. These results show that not enough patients are doing simple activities to prevent weak bones, infections and cancers that may be related to IBD.
