RESUMO

The diagnostic work-up in iron deficiency anaemia (IDA) patients can be challenging when bleedings or malabsorption are not clinically manifest. Lesions on the small bowel mucosa may cause IDA. We evaluated the prevalence of lesions on the small bowel mucosa detected at Videocapsule Endoscopy (VCE) in IDA patients following negative upper and lower endoscopies. Clinical and endoscopic data collected in 5 centres were retrieved. Lesions with a high bleeding potential (P2) were computed, and predictive factors investigated at multivariate analysis. By considering data of 230 patients, the endoscopic examination detected a total of 96 (41.7%; 95% CI: 35.4-48.1) P2 lesions on the small bowel mucosa, including 4 (1.7%) cancers. The use of non-steroidal anti-inflammatory drugs was found to be the only associated factor at both univariate (OR: 5.7, 95% CI: 2.4-13.4; P <0.001) and multivariate (OR: 2.8; 95% CI: 1.7-3.9, P <0.01) analyses. Present study showed that evaluation of small bowel mucosa with VCE allows to disclose a potential cause of IDA in near half patients. The cooperation between haematologists and gastroenterologists in the diagnostic work-up may be useful.

RESUMO

BACKGROUND: Golimumab is a new anti-TNF-alpha monoclonal antibody for patients with ulcerative colitis. AIMS: To assess the short- and long-term effectiveness and safety of golimumab in daily clinical practice and to identify predictors of response. METHODS: Consecutive patients treated with golimumab in 22 Italian centers were enrolled. Clinical, laboratory, and endoscopic data were prospectively collected before and during treatment. A subgroup of patients completed a questionnaire to assess personal satisfaction with a golimumab autoinjector system. RESULTS: A total of 196 patients were included. After 3 months, 130 patients were responders (66.3%) and showed significant reductions in mean partial, total, and endoscopic Mayo scores and in mean ESR, C-reactive protein, and fecal calprotectin levels (p < 0.001). Multivariate analysis revealed that a higher total Mayo score (p < 0.001, OR 1.5, 95% CI 1.2-1.8) and naïve status to anti-TNF-alpha (p = 0.015, OR 3.0, 95% CI 1.2-7.5) were predictive of a favorable response. Seventy-seven (39.3%) of the 130 responders maintained a response at month 12 of therapy. There were 17 adverse events, 28 patients needed hospitalization, and 15 patients underwent surgery. Self-administration of the drug was appreciated by most patients. CONCLUSIONS: The efficacy and safety of golimumab in daily clinical practice were confirmed for the short- and long-term treatment of patients with active ulcerative colitis. Patients naïve to the anti-TNF-alpha monoclonal antibody and those with a higher total Mayo score were more likely to respond to golimumab.

RESUMO

Anisakis simplex is a parasite that, if present in uncooked and contaminated saltwater fish, can invade the human gut. Two different clinical situations are recognized: the first, known as a gastrointestinal disease, varying from an asymptomatic episode to vomiting and diarrhea, and the second, classified as an adverse reaction to food, characterized by a wide spectrum of allergic reactions like rhinitis, conjunctivitis, or even anaphylaxis causing hypotension and/or shock. The intestinal epithelium, the major defense system against external molecules, represents an open gate for toxins and allergens if its protective function is compromised. Previous data have demonstrated a strict relationship between an altered intestinal permeability (I.P.) and worsening of the clinical manifestations in patients with adverse reactions to the food. In this article we evaluated the sensitization to A. simplex among patients who referred clinical symptoms of allergy. All subjects underwent commonly used alimentary skin prick test for food allergens, to which Ani s1, an A. simplex allergen, was added. In addition, in A. simplex-sensitized subjects, I.P. was determined upon their enrolment to the study (time 0) and after 6 months of consuming a raw fish-free diet (time 6). Five hundred and forty subjects were screened, and 170 had a positive skin prick test, 87 (51.2%) of whom were positive to Ani s1. Increased I.P. was evidenced in A. simplex-sensitized subjects with worse clinical symptoms, which receded after 6 months' elimination of raw seafood. With our data we demonstrated that the alimentary habit to eat raw fish represents a high risk for the integrity of the intestinal mucosa, and we suggest that this pathological situation may constitute an ideal, under-estimated, open gate for molecules that predispose to other, more important pathologies.
