RESUMEN
OBJECTIVE: STAT 3 deficiency (autosomal dominant hyper immunoglobulin E syndrome (AD-HIES)) is a primary immunodeficiency disorder with multi-organ involvement caused by dominant negative signal transducer and activator of transcription gene 3 (STAT3) mutations. We sought to describe the gastrointestinal (GI) manifestations of this disease. METHODS: Seventy subjects aged five to 60 years with a molecular diagnosis of AD-HIES were evaluated at the National Institutes of Health (NIH). Data collection involved a GI symptom questionnaire and retrospective chart review. RESULTS: In our cohort of 70 subjects, we found that 60% had GI symptoms (42/70). The most common manifestations were gastroesophageal reflux disease (GERD) observed in 41%, dysphagia in 31%, and abdominal pain in 24%. The most serious complications were food impaction in 13% and colonic perforation in 6%. Diffuse esophageal wall thickening in 74%, solid stool in the right colon in 50% (12/24), and hiatal hernia in 26% were the most prevalent radiologic findings. Esophagogastroduodenoscopy (EGD) demonstrated esophageal tortuosity in 35% (8/23), esophageal ulceration in 17% (4/23), esophageal strictures requiring dilation in 9% (2/23), and gastric ulceration in 17% (4/23). Esophageal eosinophilic infiltration was an unexpected histologic finding seen in 65% (11/17). CONCLUSION: The majority of AD-HIES subjects develop GI manifestations as part of their disease. Most notable are the symptoms and radiologic findings of GI dysmotility, as well as significant eosinophilic infiltration, concerning for a secondary eosinophilic esophagitis. These findings suggest that the STAT3 pathway may be implicated in a new mechanism for the pathogenesis of several GI disorders.

INTRODUCTION: Behçet's disease (BD) is a chronic systemic vasculitis characterized by oral and genital ulcers, uveitis, and skin lesions. Patients with BD may develop gastrointestinal (GI) disease; however, characterization of GI disease in American cohorts is lacking. In this article, we present clinical, endoscopic, and histopathologic GI findings in an American cohort of patients with BD. METHODS: Patients with established BD were evaluated prospectively at the National Institutes of Health. Demographic and clinical data were collected including BD manifestations and GI symptoms. Endoscopy with histopathologic sampling was performed for both clinical and research indications with written consent. RESULTS: Eighty-three patients were evaluated. The majority were female (83.1%) and white (75.9%). Mean age was 36 ± 14.8 years. GI symptoms were reported in 75% of cohort with nearly half of reporting abdominal pain (48.2%) and significant numbers reporting acid reflux, diarrhea, and nausea/vomiting. Esophagogastroduodenoscopy was performed in 37 patients; erythema and ulcers were the most common found abnormalities. Colonoscopy was performed in 32 patients with abnormalities including polyps, erythema, and ulcers. Endoscopy was normal in 27% of esophagogastroduodenoscopies and 47% of colonoscopies. Vascular congestion was demonstrated on the majority of random biopsies throughout the GI tract. Inflammation was not highly prevalent on random biopsies except in the stomach. Wireless capsule endoscopy was performed on 18 patients; ulcers and strictures were the most common abnormalities. DISCUSSION: GI symptoms were common in this cohort of American patients with BD. Endoscopic examination was often normal; however, histopathologic examination demonstrated vascular congestion throughout the GI tract.

Complete colonoscopy for cancer screening requires cecal intubation. Failure to reach and examine the cecum may result in missed right colon pathology. We developed and validated a novel classification scheme for the endoscopic appearance of the normal appendiceal orifice (AO). We analyzed 1,456 AO images and grouped them into four categories based on distinguishing features: "diverticuloid," "umbilicoid," "crescent," and "linear." An expert panel classified the images and modified these categories, combining crescent and linear categories into "curvilinear." A 100-image subset was classified twice by a validation cohort consisting of gastroenterology faculty and fellows. Inter-observer agreement among the expert panel, and intra- and inter-observer agreement among the validation cohort were analyzed using Fleiss' kappa statistic. The distribution of AO images was 67% curvilinear, 19% umbilicoid, and 10% diverticuloid; 85 images (4%) were not classifiable. There was substantial inter-observer agreement among the expert panel (κ, 0.72). Inter-observer agreement among the validation cohort was moderate (κ, 0.53 and 0.55 for the first and second viewing, respectively). Intra-observer κ values among the validation cohort were 0.69 for the overall classification, 0.65 for diverticuloid, 0.70 for umbilicoid, and 0.70 for curvilinear, indicating substantial agreement. This simple, validated classification scheme for the endoscopic appearance of the normal AO can be used both as a research and clinical tool to measure endoscopic quality, improve cecal examination, and document successful cecal intubation.

Anti-tumor necrosis factor-α agents are key therapeutic options for the treatment of ulcerative colitis. Their efficacy and safety have been shown in large randomized controlled trials. The key evidence gained from these trials of infliximab, adalimumab, and golimumab is reviewed along with their effect on mucosal healing and long-term outcomes. Also reviewed are methods for optimizing their effectiveness, including therapeutic drug monitoring and treat-to-target strategies. Finally, remaining unresolved questions regarding their role and effectiveness are considered including how these may be addressed in future clinical trials.
