RESUMO

BACKGROUND: Non-celiac wheat sensitivity (NCWS) most frequently presents clinically with irritable bowel syndrome (IBS)-like symptoms, although many extra-intestinal manifestations have also been attributed to it. No studies to date have evaluated the presence and frequency of gynecological symptoms in NCWS. AIM: To evaluate the frequency of gynecological disorders in patients with NCWS. PATIENTS AND METHODS: Sixty-eight women with NCWS were included in the study. A questionnaire investigating gynecological symptoms and recurrent cystitis was administered, and patients reporting symptoms were then examined by specialists. Three control groups were selected: 52 patients with IBS not related to NCWS, 56 patients with celiac disease (CD), and 71 healthy controls. RESULTS: 59% of the patients with NCWS showed gynecological symptoms, a higher frequency than in healthy controls (P = 0.04), IBS controls (P = 0.01) and CD controls (P = 0.02). Menstrual cycle alterations were more frequent in patients with NCWS than in healthy controls (26.5% vs 11.3%; P = 0.03); the patients with NCWS suffered from recurrent vaginitis (16%) and dyspareunia (6%) significantly more frequently than healthy controls. Twenty-nine percent of patients with NCWS reported recurrent cystitis, a finding higher than in the control groups (vs healthy P = 0.0001, vs IBS P = 0.001, vs CD controls P = 0.04). Microbiological examinations were negative in most of the patients with NCWS and recurrent vaginitis or cystitis. During the 1-year follow-up, 46% of patients with menstrual disorders and 36% with recurrent vaginitis reported resolution of symptoms on a wheat-free diet. CONCLUSIONS: Patients with NCWS showed a significantly higher frequency of gynecological symptoms and recurrent cystitis than patients with IBS.

RESUMO

In recent years, a new gluten- or wheat-related disease has emerged, a condition labeled "nonceliac gluten sensitivity" (NCGS) or "nonceliac wheat sensitivity" (NCWS). NCWS pathogenesis is still uncertain and attributed to very different mechanisms. We aimed to study the different T-lymphocyte subsets in the rectal mucosa of NCWS patients to demonstrate the possible contribution of adaptative immune response. Twelve patients (11 women, 1 man, age range 23-61 yr, median 32 yr) with a definitive diagnosis of NCWS were recruited at random for the present study. They underwent rectal endoscopy with multiple mucosal biopsies at the end of a double-blind placebo-controlled (DBPC) wheat challenge when they reported the reappearance of the symptoms. As controls we included 11 "healthy patients", sex- and age-matched with the patients who underwent colonoscopy evaluation for rectal bleeding due to hemorrhoids. Cells freshly obtained from rectal tissue were stained to detect anti-CD45, anti-CD3, anti-CD4, and anti-CD8. Furthermore, intracellular staining was performed with anti-tumor necrosis factor (TNF)-α, anti-interleukin (IL)-17, and anti-IL-22. Production of TNF-α by CD45+, CD3+, CD4+, and CD8+ cells, as well as of IL-17 by CD4+ cells, was higher in the rectal tissue of NCWS patients than in controls. On the contrary, IL-22 production by CD8+ cells was lower in NCWS patients than in the controls. In NCWS patients diagnosed by DBPC wheat challenge, there is a complex immunological activation, with a significant role for the adaptive response.NEW & NOTEWORTHY Nonceliac wheat sensitivity (NCWS) is a syndrome characterized by symptoms triggered by gluten intake. The pathogenesis is still uncertain. Studies have shown a role for innate immunity. We demonstrated that production of TNF-α by CD45+, CD3+, CD4+, and CD8+ cells and of IL-17 by CD4+ cells is higher in the rectal tissue of NCWS patients than in controls. We clearly demonstrated that in patients with NCWS there is a significant role for the adaptive response.

RESUMO

BACKGROUND & AIMS: Studies of non-celiac gluten or wheat sensitivity (NCGWS) have increased but there are no biomarkers of this disorder. We aimed to evaluate histologic features of colon and rectal tissues from patients with NCGWS. METHODS: We performed a prospective study of 78 patients (66 female; mean age, 36.4 years) diagnosed with NCGWS by double-blind wheat challenge at 2 tertiary care centers in Italy, from January 2015 through September 2016. Data were also collected from 55 patients wither either celiac disease or self-reported NCGWS but negative results from the wheat-challenge test (non-NCGWS controls). Duodenal and rectal biopsies were collected and analyzed by immunohistochemistry to quantify intra-epithelial CD3+ T cells, lamina propria CD45+ cells, CD4+ and CD8+ T cells, mast cells, and eosinophils and to determine the presence and size of lymphoid nodules in patients with NCGWS vs patients with celiac disease or non-NCGWS controls. RESULTS: Duodenal tissues from patients with NCGWS had significantly higher numbers of intra-epithelial CD3+ T cells, lamina propria CD45+ cells, and eosinophils than duodenal tissues from non-NCGWS controls. Duodenal tissues from patients with NCGWS and dyspepsia had a higher number of lamina propria eosinophils than patients with NCGWS without upper digestive tract symptoms. Rectal mucosa from patients with NCGWS had a larger number of enlarged lymphoid follicles, intra-epithelial CD3+ T cells, lamina propria CD45+ cells, and eosinophils than rectal mucosa from non-NCGWS controls. Duodenal and rectal mucosal tissues from patients with celiac disease had more immunocytes (CD45+ cells, CD3+ cells, and eosinophils) than tissues from patients with NCGWS or non-NCGWS controls. CONCLUSIONS: We identified markers of inflammation, including increased numbers of eosinophils, in duodenal and rectal mucosa from patients with NCGWS. NCGWS might therefore involve inflammation of the entire intestinal tract. Eosinophils could serve as a biomarker for NCGWS and be involved in its pathogenesis. Clinicaltrials.gov: NCT01762579.

RESUMO

The gastrointestinal tract of healthy individuals is colonized by hundreds of saprophytes and mycetes, especially the Candida species, are habitual ones. Under certain conditions, the fungal flora may overgrow, resulting in lesions of the digestive mucosa which, rarely, can have a local diffusion and/or spread to the lympho-hematogenous system. Mycotic infections of the stomach can sometimes look like benign gastric ulcers. Here, we present the case report of a woman, aged 64, who presented with type II diabetes mellitus and psoriasis, on chronic treatment with cyclosporin A and with endoscopic evidence of an ulcerated, vegetating gastric lesion secondary to Candida albicans infection. Although strongly suggestive of malignancy, it completely healed after cyclosporin withdrawal and the administration of oral antifungal drugs.

RESUMO

BACKGROUND: Epidemiologic studies have demonstrated that elderly patients with fixed airflow obstruction can be affected by asthma or chronic obstructive pulmonary disease (COPD). METHODS: We studied 49 consecutive elderly outpatients, presenting fixed airflow obstruction, by clinical history (smoking), pulmonary function tests, blood gas analysis, and induced sputum. RESULTS: The age was not different in patients with COPD (n=28) and asthma (n=21) (70.2+/-3.9 years vs. 69.6+/-3.7 years), also the degree of fixed airflow obstruction was similar (FEV1: 58.3+/-1.5% vs. 59.0+/-1.4% of predicted). Patients with asthma had significantly more eosinophils in peripheral blood (0.43+/-0.05x10(-3)microL vs. 0.27+/-0.1x10(-3)microL, P<0.0001), and in induced sputum (5.0% [(p25th and p75th) 5.0-6.0%] vs. 1.0% [(p25th and p75th) 0.01-1.0%]; P<0.0001), as well as serum ECP (18.6+/-4.9ng/mL vs. 7.7+/-4.7ng/mL, P<0.0001) and ECP in the induced sputum (31.6+/-2.9ng/mL vs. 5.6+/-4.9ng/mL, P<0.0001). Finally, in induced sputum the eosinophils EG2+ were higher in patients with asthma than in patients with COPD (40.5 [(p25th and p75th) 39.3-44.3] MFI vs. 3.9 [(p25th and p75th) 0-11.4] MFI, P<0.0001). They also had significantly higher diffusing capacity, and a greater reversibility to steroids, after 14-day course of therapy, whereas the reversibility to 400microg of salbutamol was similar. CONCLUSION: Despite similar fixed airflow obstruction, elderly patients with asthma have distinct characteristics compared with patients with COPD.
