Collagenous colitis associated with novel sprue-like intestinal diseases.

Almost a half-century ago, an unusual and distinct form of colitis was first recognized, collagenous colitis, characterized by sub-epithelial trichrome-positive deposits having the ultrastructural features of collagen. Later, other reports documented more extensive collagenous dis-ease in these patients, sometimes in the stomach and small bowel, a close linkage with other forms of microscopic colitis and its association with celiac and other immune-mediated diseases. Moreover, emerging genetic methods permitted large studies of collagenous colitis to complement these intriguing clinical and pathological studies.

Segmental Colitis Associated with Diverticulosis (SCAD).

Purpose Of Review: A distinctive, possibly "novel" form of a segmental inflammatory colonic disease process associated with diverticular disease (so-called SCAD or segmental-colitis-associated-diverticulosis) is reviewed.

Recent Findings: Although this phenotype of inflammatory colonic disease was initially recognized decades ago, mainly in the elderly, recent evidence from long term natural history studies along with meta-analyses confirms that its clinical course is usually benign and drug-responsive. Interestingly, its appearance in some treated with monoclonal agents (eg.

Role of biopsy in diagnosis and treatment of adult celiac disease.

Celiac disease (CD) is an immune-mediated enteropathy that characteristically responds to treatment with a gluten-free diet. In most, clinical features improve with resolution of diarrhea and weight loss. Serological studies also tend to normalize.

Dietary compliance in celiac disease.

Celiac disease is an immune-mediated disorder that causes severe architectural disturbance in the small intestinal mucosa of genetically-predisposed individuals. Impaired absorption of multiple nutrients results and diarrhea and weight loss develop. Evidence has accumulated that a strict gluten-free diet can result in resolution of diarrhea, weight gain and normalization of nutrient malabsorption.

Endocrine manifestations in celiac disease.

Celiac disease (CD) is an autoimmune small intestinal mucosal disorder that often presents with diarrhea, malabsorption and weight loss. Often, one or more associated endocrine disorders may be associated with CD. For this review, methods involved an extensive review of published English-language materials.

Segmental colitis associated diverticulosis syndrome.

Segmental colitis associated diverticulosis (SCAD) has become increasingly appreciated as a form of inflammatory disease of the colon. Several features suggest that SCAD is a distinct disorder. SCAD tends to develop almost exclusively in older adults, predominately, but not exclusively, males.

Iron deficiency anemia in celiac disease.

Iron is an important micronutrient that may be depleted in celiac disease. Iron deficiency and anemia may complicate well-established celiac disease, but may also be the presenting clinical feature in the absence of diarrhea or weight loss. If iron deficiency anemia occurs, it should be thoroughly evaluated, even if celiac disease has been defined since other superimposed causes of iron deficiency anemia may be present.

Clinical relevance of intestinal peptide uptake.

Aim: To determine available information on an independent peptide transporter 1 (PepT1) and its potential relevance to treatment, this evaluation was completed.

Methods: Fully published English language literature articles sourced through PubMed related to protein digestion and absorption, specifically human peptide and amino acid transport, were accessed and reviewed. Papers from 1970 to the present, with particular emphasis on the past decade, were examined.

Celiac disease: a disorder emerging from antiquity, its evolving classification and risk, and potential new treatment paradigms.

Celiac disease is a chronic genetically based gluten-sensitive immune-mediated enteropathic process primarily affecting the small intestinal mucosa. The disorder classically presents with diarrhea and weight loss; however, more recently, it has been characterized by subclinical occult or latent disease associated with few or no intestinal symptoms. Diagnosis depends on the detection of typical histopathological biopsy changes followed by a gluten-free diet response.

Emerging drugs for celiac disease.

Introduction: Celiac disease is an immune-mediated gluten-dependent disorder, primarily affecting the small intestine in genetically predisposed individuals. The disorder has a very heterogeneous clinical and histopathological spectrum. Current treatment with a gluten-free diet is very effective, but the diet is difficult to maintain and remains costly.

Prescriber preference for a particular tumour necrosis factor antagonist drug and treatment discontinuation: population-based cohort.

Objective: To assess the effect of physician preference for a particular tumour necrosis factor α (TNF) antagonist on the risk of treatment discontinuation in rheumatoid arthritis.

Design: Population-based cohort study.

Setting: British Columbia administrative health data (inpatients, outpatients and pharmacy).

Spontaneous free perforation of the small intestine in adults.

Spontaneous free perforation of the small intestine is uncommon, especially if there is no prior history of visceral trauma. However, free, even recurrent, perforation may complicate a defined and established clinical disorder, such as Crohn's disease. In addition, free perforation may be the initial clinical presentation of an occult intestinal disorder, such as a lymphoma complicating celiac disease, causing diffuse peritonitis and an acute abdomen.

Natural history and long-term clinical course of Crohn's disease.

Crohn's disease is a chronic inflammatory disease process involving different sites in the gastrointestinal tract. Occasionally, so-called metastatic disease occurs in extra-intestinal sites. Granulomatous inflammation may be detected in endoscopic biopsies or resected tissues.
