Mild Crohn's Disease: Definition and Management.

PURPOSE OF REVIEW: Crohn's Disease (CD) is a chronic inflammatory disease that can lead to progressive damage to the gastrointestinal tract and significant disability. Early, "top-down" biologic therapy is recommended in moderate-to-severe CD to induce remission and to prevent hospitalization and complications. However, an estimated 20-30% of patients with CD have a mild disease course and may not garner sufficient benefit from expensive, immunosuppressing agents to justify their risks. Herein, we review characteristics of patients with mild CD, the available options for disease treatment and monitoring, and future directions of research. RECENT FINDINGS: For ambulatory outpatients with low-risk, mild, ileal or ileocolonic CD, induction of remission with budesonide is recommended. For colonic CD, sulfasalazine is a reasonable choice, although other aminosalicylates have no role in the treatment of CD. No large, randomized trial has supported the use of antibiotics or antimycobacterials in the treatment of CD. Partial Enteral Nutrition and Crohn's Disease Exclusion Diets may be appropriate for inducing remission in some adult patients, with trials ongoing. Select patients with mild-to-moderate CD may benefit from maintenance therapy with azathioprines or gut specific biologics, such as vedolizumab. The role of complementary and alternative medicine is not well defined. The identification, risk stratification, and monitoring of patients with mild CD can be a challenging clinical scenario. Some patients with low risk of disease progression may be appropriate for initial induction of remission with budesonide or sulfasalazine, followed by close clinical monitoring. Future research should focus on pre-clinical biomarkers to stratify disease, novel therapies with minimal systemic immune suppression, and validation of rigorous clinical monitoring algorithms.

TNF-α inhibition in the setting of undiagnosed HIV infection: a call for enhanced screening guidelines.

BACKGROUND: Despite the risks of immunosuppression, recommendations regarding screening for HIV infection prior to initiation of biologic therapies targeting common rheumatologic disorders, including inflammatory bowel disease (IBD) and inflammatory arthritides, are limited. Few cases of patients started on biologics while living with undiagnosed HIV infection have been reported. METHODS: We report three cases of patients initiated on biologics in the absence of recent or concurrent HIV screening who developed refractory disease or unanticipated complications and were later found to have undiagnosed chronic HIV infection. RESULTS: In Case 1, a 53-year-old MSM with negative HIV testing 2 years prior presented with presumed rheumatoid arthritis. He did not respond to methotrexate, so adalimumab was started. HIV testing to evaluate persistent symptoms was positive 9 months later; CD4+ T-cell count was 800 cells/µl. Antiretroviral therapy (ART) resulted in resolution of symptoms, which were attributed to HIV-associated arthropathy. In Case 2, a 55-year-old woman with injection drug use in remission and no prior HIV testing presented with hidradenitis suppurativa. She started infliximab and methotrexate therapy with good response. After she developed weight loss and lymphopenia, an HIV test was positive; CD4+ T-cell count was 334 cells/µl. Biologic hidradenitis suppurativa therapy was discontinued, with subsequent poor hidradenitis suppurativa control. In Case 3, a 32-year-old MSM with no prior HIV testing presented with presumed IBD; infliximab and steroids were started. Symptoms progressed despite IBD-directed therapy, and he was diagnosed with extensive Kaposi sarcoma with visceral and cutaneous involvement, likely exacerbated by immunosuppression. HIV testing was positive; CD4+ T-cell count was 250 cells/µl. Kaposi sarcoma initially worsened due to ART-associated immune reconstitution inflammatory syndrome. He is now improving with systemic chemotherapy and ART. HIV-associated Kaposi sarcoma is presumed to be the underlying diagnosis. CONCLUSION: All three patients had elevated risk for HIV infection, and two had final diagnoses attributed to chronic HIV infection, not warranting therapeutic immunosuppression. Screening for HIV infection prior to initiation of biologic therapy should be incorporated into clinical practice guidelines.

Fecal microbial transplant for inflammatory bowel disease.

PURPOSE OF REVIEW: The purpose of this brief review is to investigate the current utility of fecal microbial transplantation (FMT) to ameliorate dysbiosis contributing to inflammatory bowel disease pathogenesis. RECENT FINDINGS: Increasing data from randomized, controlled trials support a role for multiple FMT administrations in the induction of remission and even as a maintenance therapy in mild-to-moderate Ulcerative Colitis. Small series and one small randomized controlled trial among patients with Crohn's Disease and with pouchitis continue to produce conflicting clinical results and microbial profile data on the host and donor levels. It is not clear whether patients with Crohn's disease are more susceptible to disease flare after FMT. Novel FMT delivery systems, including oral, and early-intensity colonoscopic devices, are under investigation. SUMMARY: The allure of minimizing the risks and cost of long-term immunosuppression via modulation of patient microbiota remains enticing, and the most recent randomized controlled data in ulcerative colitis reveals acceptable clinical remission rates. However, prior to wide adoption of FMT within the inflammatory bowel disease treatment armamentarium, large clinical trials identifying biomarkers of treatment success, ensuring safety across all indications, and cultivating optimized donor and host selection are needed.

Body Image Dissatisfaction among Pediatric Patients with Inflammatory Bowel Disease.

OBJECTIVES: To determine risk factors for body image dissatisfaction among pediatric patients with inflammatory bowel disease (IBD). STUDY DESIGN: We performed a cross-sectional study of children aged 9-18 years in the IBD Partners Kids & Teens cohort. Participants completed surveys including demographics, disease characteristics and activity indices, and psychosocial outcomes measured by IMPACT-III questionnaires. We defined body image dissatisfaction if participants answered "I look awful" or "I look bad." Bivariate analyses assessed associations between body image dissatisfaction and demographic, disease-related and psychosocial factors; logistic regression models evaluated associations between risk factors and body image dissatisfaction. RESULTS: IMPACT-III was completed by 664 patients, with 74 (11.1%) reporting body image dissatisfaction. Patients with body image dissatisfaction were more likely to be female (P < .01), older (median age 15 vs 13 years, P < .01), and diagnosed with IBD at an older age (12 vs 10 years, P < .01). Those with body image dissatisfaction had greater body mass index percentile (P = .02), more active disease (P < .01), more current steroid use (P < .01), and more depression and anxiety (P < .01). Female sex (OR 2.31; 95% CI 1.22-4.39), depression (OR 4.73; 95% CI 2.41-9.26), and anxiety (OR 5.42; 95% CI 2.48-11.80) were independently associated with body image dissatisfaction. CONCLUSIONS: In this cohort, risk factors for body image dissatisfaction include female sex, older age at diagnosis, active disease, current steroid use, greater body mass index, and comorbid mood disorder. Interventions targeting modifiable risk factors for body image dissatisfaction may improve quality of life in pediatric patients with body image dissatisfaction.

Colonic Involvement of Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis: A Rare Cause of Gastrointestinal Bleeding.

Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) represents a spectrum of rare but severe mucocutaneous drug reactions. Gastrointestinal involvement of SJS/TEN is associated with high morbidity and mortality and often presents 2-3 weeks after the initial appearance of skin lesions. There are no evidence-based treatment algorithms for the management of SJS/TEN. We report a case of life-threatening gastrointestinal bleeding from colonic involvement of SJS/TEN and discuss potential therapeutic options.
