A Cross-Sectional Study of the Prevalence of Gastrointestinal Symptoms and Pathology in Patients With Common Variable Immunodeficiency.

Objectives: The objective of this study was to study the prevalence of gastrointestinal (GI) symptoms and histopathology in patients with common variable immunodeficiency (CVID) as well as linking the findings to GI infections and markers of systemic immune activation.

Methods: In this cross-sectional study, we addressed GI symptoms in 103 patients and GI histopathological findings in 53 patients who underwent upper and lower endoscopic examination. The most frequent histopathological findings were linked to GI symptoms, B-cell phenotype, and markers of systemic immune activation (soluble (s)CD14, sCD25, and sCD163).

Mucosal cytokine response after short-term gluten challenge in celiac disease and non-celiac gluten sensitivity.

Objectives: In celiac disease (CD), gluten induces both adaptive and innate immune responses. Non-celiac gluten sensitivity (NCGS) is another form of gluten intolerance where the immune response is less characterized. The aim of our study was to explore and compare the early mucosal immunological events in CD and NCGS.

The load of short telomeres is increased and associated with lifetime number of depressive episodes in bipolar II disorder.

Background: It has recently been hypothesized that bipolar disorders are associated with accelerated aging. Telomere dysfunction, a biomarker of aging, is determined by the load of short telomeres, rather than by the mean telomere length. To our knowledge, the load of short telomeres has not been reported in any psychiatric disorder.

Intestinal malabsorption of D-xylose: comparison of test modalities in patients with celiac disease.

Objective: The aim of the study was to compare three different D-xylose test modalities for small intestinal malabsorption, using patients with celiac disease and healthy persons as experimental models.

Material And Methods: Ninety-one untreated celiac patients, 98 treated celiac patients, and 43 healthy subjects performed the (13)C-D-xylose breath test. 1-h plasma D-xylose levels were measured in 48 untreated patients, 41 treated patients and 41 healthy controls.

Selective COX-2 inhibition affects fatty acids, but not COX mRNA expression in patients with FAP.

Familial adenomatous polyposis (FAP) provides a model for sporadic colorectal cancer development. Cyclooxygenase (COX) inhibition may ameliorate polyp development, but rofecoxib was withdrawn due to cardiovascular side effects. Although this selective COX-2 inhibitor, like diet, may alter the fatty acid and eicosanoid pattern, data on the potential alteration in tissues after use, are scarce.

Serum nutrients and habitual dietary intake in colectomized FAP patients in Norway.

Background: Patients with familial adenomatous polyposis (FAP) are colectomized in young age in order to avoid development of colorectal cancer. Because colectomy radically changes gastrointestinal physiology, and food avoidance may be present, colectomized patients may be at risk for nutritional deficiency.

Aim Of The Study: to evaluate: (1) serum biochemical levels as compared to reference; (2) dietary intake as compared to the recommendations.

No induction of anti-avenin IgA by oats in adult, diet-treated coeliac disease.

Objective: Coeliac disease is effectively treated with a gluten-free diet devoid of wheat, rye, barley and related cereals. Oats has until recently also been considered harmful but is now allowed in several countries. We have, however, identified three adult coeliac disease patients who developed a flare of active coeliac disease after ingestion of oats, which suggests that oats might not be entirely innocent in coeliac disease.

Effect of elemental diet on mucosal immunopathology and clinical symptoms in type 1 refractory celiac disease.

Background & Aims: Patients with celiac disease (CD) who do not improve or exhibit villous atrophy on a gluten-free diet may have type 1 refractory CD (RCD) with a polyclonal mucosal T-cell infiltrate, or type 2 RCD with a monoclonal infiltrate, also termed cryptic T-cell lymphoma. Both conditions are difficult to treat. Here we describe the effects of a nonimmunogenic elemental diet on clinical symptoms and mucosal immunopathology in type 1 RCD.
