Celiac disease seroprevalence in patients with infertility. A case-control study.

Background: Although most patients with celiac disease (CD) have digestive manifestations, in some of them they may be of extraintestinal (atypical) nature, such as chronic anemia, ataxia, and fertility disorders.

Objective: To determine the prevalence of CD-related antibodies in Mexican women with fertility disorders.

Material And Methods: Case-control study of women who attended evaluation for fertility disorders in a specialized center.

Metabolic effects in patients with celiac disease, patients with nonceliac gluten sensitivity, and asymptomatic controls, after six months of a gluten-free diet.

Introduction And Objectives: It is essential for patients with celiac disease (CD) to be on a gluten-free diet (GFD) but said diet has also been reported to increase the risk for metabolic syndrome. There is no evidence on the metabolic effects of a GFD in patients with nonceliac gluten sensitivity (NCGS) or in asymptomatic subjects. Therefore, the aim of the present study was to evaluate the metabolic effects of a GFD over a 6-month period in patients with CD, patients with NCGS, and in asymptomatic controls (ACs).

Eosinophilic esophagitis prevalence in an adult population undergoing upper endoscopy in southeastern Mexico.

Eosinophilic esophagitis (EoE) prevalence fluctuates according to the population studied and varies from 0.4% in an open population to 6.5% in subjects with esophageal symptoms.

Esophageal motor disorders in subjects with incidentally discovered Chagas disease: a study using high-resolution manometry and the Chicago classification.

In patients with chronic indeterminate Chagas disease, conventional manometry has shown that 25-48% had esophageal motor disorders. Recently, esophageal high-resolution manometry (HRM) has revolutionized the assessment of esophageal motor function. In this study, we performed esophageal HRM in a group of subjects with incidentally positive serological findings for Trypanosoma cruzi.

[Comparative analysis between breath test, serological immunoassay and rapid-urease test for detection of Helicobacter pylori infection in Mexican patients with non-investigated dyspepsia].

Introduction: There are multiple Helicobacter pylori (Hp) detection tests, some are invasive and other noninvasive. The diagnostic accuracy of these methods varies according to the prevalence of the disease.

Objective: To determine the diagnostic accuracy of the breath test, serology and rapid urease test, considering gastric biopsy with Giemsa stain as the gold standard in Hp-infected subjects with uninvestigated dyspepsia.
