Endoscopically Active Ulcerative Colitis Is Associated With Asymptomatic Atherosclerotic Vascular Disease: A Case-Control Study.

BACKGROUND: Chronic inflammation in immune-mediated conditions has been associated with an increased risk in atherosclerotic disease. There is paucity of evidence regarding the prevalence of asymptomatic atherosclerosis in patients with ulcerative colitis (UC) and its association with disease activity. We sought to compare the prevalence of asymptomatic atherosclerotic disease between young patients with UC with and without mucosal healing (MH) and healthy control individuals. METHODS: An observational study was conducted in 2 hospitals in Buenos Aires, Argentina. Patients with UC 18 to 50 years of age with at least 1 previous colonoscopy in the last year were enrolled, along with age- and sex-matched healthy control individuals. Carotid and femoral ultrasound assessments were performed to determine the prevalence of atherosclerotic lesions and abnormal intima-media thickness (IMT). We compared the prevalence of atherosclerotic disease and the prevalence of abnormally increased IMT in at least 1 vascular territory. RESULTS: Sixty patients with UC and 60 healthy control individuals were enrolled. Mean age was 38 years and 53.33% were men. Although the prevalence of atherosclerotic lesions was similar in patients with UC without MH when compared with both patients with UC with MH and control individuals (3.7% vs 0% vs 6.67%; P = .1), we found a significant increase in abnormal IMT in at least 1 vascular territory in UC patients without MH when compared with healthy control individuals (48.15% vs 26.67%; P = .05). CONCLUSIONS: Patients with UC with active mucosal inflammation showed a significantly increased odds of asymptomatic femoral or carotid vascular disease when compared with control individuals.

Young patients with endoscopically active ulcerative colitis showed a significantly higher prevalence of abnormal intima-media thickness when compared with control individuals. Among patients with ulcerative colitis, age, disease duration, and C-reactive protein were associated with increased odds of asymptomatic vascular lesions.

IgA Deficiency Is Not Systematically Ruled Out in Patients Undergoing Celiac Disease Testing.

BACKGROUND: Guidelines for celiac disease (CD) testing recommend total serum IgA determination alongside anti-transglutaminase IgA antibodies. It is not well known if lack of serum IgA determination is a common finding in clinical practice. AIM: To determine the prevalence of lack of serum IgA determination among patients screened for celiac disease. MATERIALS AND METHODS: We identified all subjects who underwent serum anti-transglutaminase IgA and/or other CD-related antibodies determination at a single teaching hospital in Buenos Aires from October 2019 to February 2020. Medical records were reviewed to select adult patients who were tested for celiac disease. The primary outcome was the proportion of patients with inadequate testing for celiac disease due to lack of serum IgA determination. We retrieved the following variables from each patient's record: age, gender, body mass index, symptoms present at screening, first-grade family history of CD, history of type-1 diabetes mellitus, autoimmune hypothyroidism, Down's syndrome. RESULTS: Overall, 1122 patients were included for analysis. Lack of serum IgA determination prevalence was 20.49%. Among patients who did have serum IgA determination, the prevalence of IgA deficiency was 5.16%. The following variables were independently associated with a significantly increased odds of serum IgA determination: diarrhea [OR 1.55 (1.01-2.34)] and abdominal pain [OR 2.28 (1.44-3.63)]; higher body mass index [OR 0.91 (0.85-0.98)], osteoporosis [OR 0.49 (0.28-0.89)], hypothyroidism [OR 0.18 (0.07-0.45)], arthralgia/arthritis [OR 0.47 (0.27-0.85)], or testing by endocrinologist [OR 0.46 (0.23-0.91)] and gynecologist [OR 0.14 (0.06-0.31)] were inversely associated. CONCLUSION: IgA deficiency is not systematically ruled out in a relatively high proportion of patients undergoing serological screening of celiac disease.

[Endoscopic ultrasound-guided hepaticogastrostomy for treatment of malignant biliary obstruction in patient with Roux-en-Y gastrectomy]. / Hepático-gastrostomía guiada por eco endoscopia en obstrucción biliar maligna y gastrectomía subtotal con reconstrucción en Y de Roux.

Endoscopic retrograde cholangiography with biliary stenting is the generally recognized optimal treatment of malignant biliary obstruction. This procedure, though, is challenging in patients with surgically altered anatomy. Endoscopic ultrasound (EUS) enables tissue sampling by means of fine-needle aspiration and also represents an alternative recourse for biliary drainage in preference to a percutaneous approach. We aimed to report a case in which EUS enabled a definitive diagnosis of the recurrence of oncologic disease and the relief of biliary obstruction in a patient with a surgically altered anatomy.

RESUMEN La colangiopancreatografía retrógrada endoscópica (CPRE) representa el tratamiento de primera línea para el drenaje biliar en pacientes con obstrucción biliar maligna avanzada. Sin embargo, este procedimiento representa un desafío en pacientes con anatomía alterada quirúrgicamente. El ultrasonido endoscópico (USE) permite la toma de muestras de tejido mediante punción aspiración con aguja fina y también representa una alternativa de drenaje biliar al abordaje percutáneo o quirúrgico. Nuestro objetivo es comunicar un caso en el que la ecoendoscopia permitió el diagnóstico definitivo de la recurrencia de la enfermedad oncológica de base y el alivio de la obstrucción biliar en un paciente con anatomía alterada quirúrgicamente.
