Racial and Ethnic Disparities in Patients With Inflammatory Bowel Disease: An Online Survey.

BACKGROUND: Data regarding care access and outcomes in Black/Indigenous/People of Color/Hispanic (BIPOC/H) individuals is limited. This study evaluated care barriers, disease status, and outcomes among a diverse population of White/non-Hispanic (W/NH) and BIPOC/H inflammatory bowel disease (IBD) patients at a large U.S. health system. METHODS: An anonymous online survey was administered to adult IBD patients at Ochsner Health treated between Aug 2019 and Dec 2021. Collected data included symptoms, the Consumer Assessment of Healthcare Providers and Systems and Barriers to Care surveys, health-related quality of life (HRQOL) via the Short Inflammatory Bowel Disease Questionnaire, the Medication Adherence Rating Scale-4, and the Beliefs about Medicines Questionnaire. Medical record data examined healthcare resource utilization. Analyses compared W/NH and BIPOC/H via chi-square and t tests. RESULTS: Compared with their W/NH counterparts, BIPOC/H patients reported more difficulties accessing IBD specialists (26% vs 11%; P = .03), poor symptom control (35% vs 18%; P = .02), lower mean HRQOL (41 ± 14 vs 49 ± 13; P < .001), more negative impact on employment (50% vs 33%; P = .029), worse financial stability (53% vs 32%; P = .006), and more problems finding social/emotional support for IBD (64% vs 37%; P < .001). BIPOC/H patients utilized emergency department services more often (42% vs 22%; P = .004), reported higher concern scores related to IBD medication (17.1 vs 14.9; P = .001), and worried more about medication harm (19.5% vs 17.7%; P = .002). The survey response rate was 14%. CONCLUSIONS: BIPOC/H patients with IBD had worse clinical disease, lower HRQOL scores, had more medication concerns, had less access to specialists, had less social and emotional support, and used emergency department services more often than W/NH patients.

This study examined care access and outcomes in a diverse population of inflammatory bowel disease patients, comparing White/non-Hispanic and Black/Indigenous/People of Color/Hispanic individuals. The analysis revealed that Black/Indigenous/People of Color/Hispanic patients reported greater difficulties accessing inflammatory bowel disease specialists, poorer symptom control, and lower quality of life, and faced challenges in employment, financial stability, and finding social/emotional support. Additionally, they utilized emergency department services more frequently, expressed higher medication concerns, and had increased worries about medication harm.

Ulcerative colitis immune cell landscapes and differentially expressed gene signatures determine novel regulators and predict clinical response to biologic therapy.

The heterogeneous pathobiology underlying Ulcerative Colitis (UC) is not fully understood. Using publicly available transcriptomes from adult UC patients, we identified the immune cell landscape, molecular pathways, and differentially expressed genes (DEGs) across patient cohorts and their association with treatment outcomes. The global immune cell landscape of UC tissue included increased neutrophils, T CD4 memory activated cells, active dendritic cells (DC), and M0 macrophages, as well as reduced trends in T CD8, Tregs, B memory, resting DC, and M2 macrophages. Pathway analysis of DEGs across UC cohorts demonstrated activated bacterial, inflammatory, growth, and cellular signaling. We identified a specific transcriptional signature of one hundred DEGs (UC100) that distinctly separated UC inflamed from uninflamed transcriptomes. Several UC100 DEGs, with unidentified roles in UC, were validated in primary tissue. Additionally, non-responders to anti-TNFα and anti-α4ß7 therapy displayed distinct profiles of immune cells and pathways pertaining to inflammation, growth, and metabolism. We identified twenty resistant DEGs in UC non-responders to both therapies of which four had significant predictive power to treatment outcome. We demonstrated the global immune landscape and pathways in UC tissue, highlighting a unique UC signature across cohorts and a UC resistant signature with predictive performance to biologic therapy outcome.

Open-label prospective therapeutic clinical trials: oral vancomycin in children and adults with primary sclerosing cholangitis.

BACKGROUND: Oral vancomycin (OV) in primary sclerosing cholangitis (PSC) has been evaluated as a potential therapeutic agent. We report the long-term biochemical course and outcomes of patients with PSC treated with OV. METHODS: Patients were enrolled in 2 open-label clinical trials (ClinicalTrials.gov Identifier: NCT01802073 and NCT01322386) and offered OV at 50 mg/kg/day in 3 divided doses if weight <30kg, and 500 mg 3 times/day if weight ≥30kg. Patients with biliary strictures requiring stenting or awaiting liver transplant were excluded. Liver biochemistry, MRCP and histology were documented at baseline and while on OV. The primary outcome was a decrease in elevated gamma glutamyl transferase (GGT), alkaline phosphatase (ALP), and/or alanine aminotransferase (ALT) from baseline. RESULTS: 30 subjects were enrolled, and 29 additional subjects who learned of the clinical trial requested OV (total n = 59; median age was 13.5 years [range, 1.5-44 years]; 64.4% were male; and 94.9% had inflammatory bowel disease [IBD]). The median treatment duration was 2.7 years (range, 0.2-14 years). Ninety-six percent (57/59), 81.3% (48/59), and 94.9% (56/59) experienced reduction of GGT, ALP, and ALT, respectively. Furthermore, 39% (23/59), 22% (13/59), and 55.9% (33/59) experienced normalization of GGT, ALP, and ALT, respectively, within the first 6 months of OV treatment. One patient underwent liver transplantation 8 years after beginning OV treatment, and one developed biliary strictures requiring endoscopic intervention. OV was well-tolerated by patients, and no patient developed treatment-related adverse events. CONCLUSION: In PSC, OV was well-tolerated and was associated with improvement in liver chemistry. A randomized placebo-controlled clinical trial is warranted.

Prevalence and factors associated with gluten sensitivity in inflammatory bowel disease.

OBJECTIVES: Gluten sensitivity (GS) arises with celiac disease and has also been found in non-celiac disorders, although its characteristics in inflammatory bowel disease (IBD) are unclear. This study evaluated the prevalence of GS and factors associated with GS in IBD. METHODS: Adult IBD patients at a tertiary-care medical center completed a survey of their demographics, medical history, family history, social history and symptoms. Data on IBD characteristics were abstracted from the medical records. Descriptive analyses estimated the prevalence of GS. Multivariable logistic regression assessed the association between GS and patient or disease factors. RESULTS: Of 102 IBD patients (55 Crohn's disease [CD], 46 ulcerative colitis [UC] and 3 IBD-unclassified), GS was reported in 23.6 and 27.3% of CD and UC patients, respectively. Common symptoms included fatigue, abdominal pain, diarrhea, bloating and hematochezia. There was no difference in these symptoms when comparing patients with and without GS. When evaluating IBD-related factors, GS was associated with having had a recent flare (adjusted odds ratio [aOR] 7.4; 95% confidence interval [CI] 1.6-34.1), stenotic disease in CD (aOR 4.7; 95% CI 1.1-20.2) and dermatologic manifestations (aOR 5.5; 95% CI 1.2-24.1). CONCLUSION: GS was common in IBD and associated with having had a recent flare. GS may be transient for some patients, whereby dietary recommendations during and after a flare could focus on the avoidance of specific food triggers with possible reintroduction of these foods over time. This study prompts further prospective investigation into the temporal evolution of GS in IBD.

Effects of caregiver burden on quality of life and coping strategies utilized by caregivers of adult patients with inflammatory bowel disease.

BACKGROUND: While previous studies have evaluated caregivers' quality of life (QOL), burnout, and stress amongst across a variety of chronic illnesses, few such studies have been related to inflammatory bowel disease (IBD). METHODS: Caregivers accompanying adult patients with IBD at 6 tertiary centers were enrolled. They completed self-administered surveys related to QOL and burden, including the QOL scale, Zarit Burden Interview (ZBI), and Brief COPE. RESULTS: Of the 200 consecutive caregivers asked to participate, 162 (81.0%) enrolled and completed the survey. A total of 43.8% caregivers reported having a high level of burden as measured by the ZBI. Factors predictive of a high burden included female gender, younger age of caregiver, household income <$30,000, having more than one dependent in the household, caring for a patient with active disease and higher disease severity, and a personal history of psychiatric illness. Over one third of the caregivers reported a maladaptive coping pattern. The caregiver factors predictive of maladaptive coping skills included male gender, lack of involvement in a support group, a personal history of psychiatric illness, and living in a different household from the patient. CONCLUSIONS: A large proportion of caregivers of IBD patients experience a high level of caregiver burden and reduced QOL. Participation in religious/spiritual activities and support groups appeared to reduce perceived caregiver burden and improve QOL. This study suggests there is an unmet need to address the caregiver burden of adult IBD patients.

Prevalence of Anal Dysplasia in Patients With Inflammatory Bowel Disease.

BACKGROUND & AIMS: Although the prevalence of anal dysplasia is higher in some immunosuppressed populations, the prevalence in patients with inflammatory bowel disease (IBD) is unknown. We examined the prevalence of abnormal anal cytology among IBD patients, and its relation to the human papilloma virus (HPV). METHODS: Adults with IBD and age-matched healthy controls (HC) were recruited. IBD patients were categorized as nonimmunosuppressed (IBD-N) or immunosuppressed (IBD-I). Anal Papanicolaou tests were performed for HPV testing and classification by a cytopathologist as follows: negative, atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion, high-grade squamous intraepithelial lesion, cancer, or unsatisfactory. RESULTS: A total of 270 subjects (100 IBD-I, 94 IBD-N, and 76 HC) were recruited. ASC-US were detected in 19 subjects, with a trend toward a higher prevalence among IBD subjects compared with HC (8.8% vs 2.6%; P = .10). The prevalence did not differ with respect to immunosuppression. Crohn's disease (CD) subjects had a higher prevalence of ASC-US compared with others with IBD (P = .02). Among those with CD, female sex and disease duration longer than 10 years were risk factors. There were no cases of low-grade squamous intraepithelial lesion, high-grade squamous intraepithelial lesion, or anal cancer in the cohort. HPV was present in 5.3% and 1.5% of subjects with and without ASC-US, respectively (P = .26). CONCLUSIONS: Although there was a trend toward abnormal anal Papanicolaou tests in IBD subjects compared with HC, there was no difference based on immunosuppression. The presence of HPV did not correlate with abnormal anal cytology. Risk factors associated with this increased trend include female CD subjects and those with a longer duration of CD.

Coping Strategies Used by Adult Patients with Inflammatory Bowel Disease.

OBJECTIVES: Symptoms of and treatments for inflammatory bowel disease (IBD) have a significant impact on patients' quality of life (QOL) and result in an increased prevalence of depression and anxiety disorders. Little is known about the type of coping strategies used by adult patients with IBD to better cope with their chronic illness, however. The objectives of this study were to identify the types of coping styles and their impact on the QOL of patients with IBD. METHODS: The first 150 consecutive participants with IBD were recruited at five major tertiary hospitals and given an anonymous survey consisting of demographic information, the Jalowiec Coping Scale, and the Shortened Inflammatory Bowel Disease Questionnaire. RESULTS: The cohort was 51.3% men and included 150 participants with a mean age of 39.3 years. The primary coping mechanisms used were confrontive (46.7%), evasiveness (30.0%), optimistic (18.7%), and fatalistic (4.6%) coping. Participants rated confrontive (62.0%), optimistic (26.6%), and evasive (11.4%) coping styles as the most effective. Those who reported an increased frequency of flares scored lower on QOL (P <0.05) and more often used evasive and fatalistic coping styles (P < 0.05) compared with other coping strategies; however, after controlling for disease activity, QOL was significantly better for those who primarily used adaptive coping styles compared with those who used maladaptive styles (P <0.001). CONCLUSIONS: We demonstrated that confrontive, evasive, and optimistic styles of coping are most widely used among patients with IBD. Despite controlling for disease activity, we demonstrated that those who used adaptive coping styles had a higher QOL compared with those who used maladapative coping styles. Future research on coping is warranted to assess coping styles on therapeutic compliance and disease perception.

Incidence and risk of intestinal and extra-intestinal complications in Medicaid patients with inflammatory bowel disease: a 5-year population-based study.

BACKGROUND AND AIM: Intestinal and extra-intestinal complications are associated with inflammatory bowel disease (IBD) but their exact incidence is not well known. In order to improve our understanding of their incidence and impact, we assessed the complications associated with ulcerative colitis (UC) and Crohn's disease (CD) in a population-based study in Medicaid patients. METHODS: We utilized a retrospective cohort design and identified cases of UC and CD using Medi-Cal, the Medicaid program for the State of California. The disease cohort was age- and gender-matched to four controls each and the intestinal and extra-intestinal complications of CD and UC (analyzed separately) were studied over a period of 5 years following the initial diagnosis. RESULTS: For UC, the total number of intestinal complications, per 100 cases, was 92 observed compared to 21 expected; the total number of extra-intestinal complications was 42 observed compared to 30 expected. For CD, the number of intestinal complications was 81 observed compared to 20 expected and for extra-intestinal complications, 37 observed compared to 26 expected (all p < 0.001). For both UC and CD, bleeding was the most frequently seen intestinal complication, while the most common extra-intestinal complication was osteoporosis. CONCLUSIONS: IBD is associated with several intestinal and extra-intestinal complications of variable incidence and risk. Success of therapeutic regimens should be measured by decreases in incidence, risks, and costs of these complications, in addition to the usual impact on disease activity.

Risks and benefits of the use of concomitant immunosuppressives and biologics in inflammatory bowel disease.

With the introduction of biologic therapies for inflammatory bowel disease, significant questions have arisen regarding their best optimization. Although initial recommendations were to combine immunosuppressives with biologics to reduce immunogenicity, trials with 3 different anti-tumor necrosis factor agents (infliximab, adalimumab, and certolizumab) and a humanized monoclonal antibody that targets alpha-4 integrins (natalizumab) have failed to demonstrate the clinical superiority of combination therapy when high-dose induction and scheduled maintenance therapy was prescribed for up to 1 year. However, immunosuppressive agents should be considered with episodic biologic therapy to decrease immunogenicity and secondary loss of response. The issue of whether induction with biologics and maintenance therapy with immunosuppressives as monotherapy is as safe and effective as induction and maintenance with biologics alone still remains to be addressed. Further, with the use of concomitant immunosuppressives and biologics, evolving data raise concerns for an increase in adverse events, including opportunistic infections, neurological disorders, and cancer. Specific therapeutic decisions need to be individualized and the clinician must help the patient weigh quality-of-life issues with readiness to assume possible risks.
