According to previous studies in captive cheetah ( Acinonyx jubatus ) populations, one of the most threatening diseases besides amyloidosis, myelopathy, veno occlusive disease, and gastritis, is renal failure. Contrary to captive cheetahs in North America and South Africa, morphological data concerning renal lesions in the cheetah European Endangered Species Program (EEP) are lacking. This study details the histological characterization as well as immunohistochemical and morphometrical analysis of nephropathies in 35 captive cheetahs from the EEP, which were necropsied between 1985 and 2003...

There are few data in the literature on microscopic gastritis and colitis in the pediatric population. The diagnosis is often made after the occurrence of complications. We report the case of a 10.5 year-old girl for whom the diagnosis was made several years after the initial symptoms. Test for infections, inflammation, and auto-immunity yielded normal results. Upper endoscopy and colonoscopy revealed an abnormal mucosa. However, histology showed microscopic inflammation and fibrotic lesions in the lamina propria, and a thick subepithelial collagenous band...

Korean Red Ginseng (KRG) is an herbal medicine prescribed worldwide that is prepared from Panax ginseng C.A. Meyer (Araliaceae). Out of ginseng's various components, ginsenosides are regarded as the major ingredients, exhibiting anticancer and anti-inflammatory activities. Although recent studies have focused on understanding the anti-inflammatory activities of KRG, compounds that are major anti-inflammatory components, precisely how these can suppress various inflammatory processes has not been fully elucidated yet...

Cytotoxic T lymphocyte antigen-4 (CTLA-4) is essential for immunological (self-) tolerance, but due to the early fatality of CTLA-4 KO mice, its specific function in central and peripheral tolerance and in different systemic diseases remains to be determined. Here, we further examined the role of CTLA-4 by abrogating CTLA-4 expression in adult mice and compared the resulting autoimmunity that follows with that produced by congenital CTLA-4 deficiency. We found that conditional deletion of CTLA-4 in adult mice resulted in spontaneous lymphoproliferation, hypergammaglobulinemia, and histologically evident pneumonitis, gastritis, insulitis, and sialadenitis, accompanied by organ-specific autoantibodies...

Hypogammaglobulinemia/common variable immunodeficiency (CVID) may lead to disruption of the gut mucosal immune barrier. Collagenous infiltrative disorders of the intestinal tract (colitis, gastritis, sprue) constitute a relatively new spectrum of gastrointestinal disorders. Our aims were (1) to determine the association between immunoglobulin deficiency state like CVID and collagenous infiltrative disorders of the gut and (2) to study the clinic-pathologic characteristics and treatment outcomes in these patients...

Collagenous gastritis is an extremely rare disease, both in children and adults. Symptoms vary depending on the extent of collagenous changes in the bowel. In most of the children, iron deficiency anemia and abdominal pain are the presenting symptoms. We present a 15-year-old boy with acute abdomen due to gastric perforation the cause of which was collagenous gastritis.

The mucosa of the esophagus, the stomach, the small intestine, the large intestine and rectum are unremittingly challenged by adverse micro-environmental factors, such as ingested pathogenic and non-pathogenic bacteria, and harsh secretions with digestive properties with disparate pH, as well as bacteria and secretions from upstream GI organs. Despite the apparently inauspicious mixture of secretions and bacteria, the normal GI mucosa retains a healthy state of cell renewal. To by-pass the tough microenvironment, the epithelia of the GI react by speeding-up cell exfoliation, by increasing peristalsis, eliminating bacteria through secretion of plasma cell-immunoglobulins and by increasing production of natural antibacterial enzymes (lysozyme) and host defense peptides (defensin-5)...

Collagenous gastritis (CG) is a rare disorder characterized by the thick collagenous subepithelial bands associated with mucosal inflammation. There have been approximately fifty reports in the literature since it was first described in 1989. According to previous reports, CG is heterogeneous and classified into two groups-(1) cases limited to the gastric mucosa in children or young adults, and (2) CG associated with collagenous colitis in elderly adults presenting with chronic watery diarrhea. In Japan, only nine previous cases were reported, and all of them were young adults...

Ultrastructural changes of gastritis due to infection with Physaloptera clausa in 12 fresh carcasses of euthanized European hedgehogs (Erinaceus europaeus) collected from different part of Urmia, Iran, in which they were highly populated with this animal, six females and six males were subjected to detail necropsy with special reference to the stomach. Macroscopic changes of stomach were recorded and some of the worms collected. Based on number of parasites present in the stomach, they were divided into light infection, mild infection, and severe infection...

Collagenous gastritis (CG) is an uncommon condition known in the pediatric age. It is characterized by the presence of subepithelial collagen bands (> 10 microm) associated with lymphoplasmacytic infiltration of the stomach's lamina propria. Symptoms manifested by patients with CG may be common with many other disorders. It typically manifests with epigastralgia, vomiting, and iron deficiency during pre-adolescence. This condition's pathophysiology remains unclear. In contrast to adults, where association with collagenous colitis and other autoimmune conditions is more common, pediatric involvement is usually confined to the stomach...

Collagenous gastritis is a rare condition characterized by surface epithelial damage, subepithelial collagen deposition, and a lamina propria inflammatory infiltrate. Previous studies have proposed 2 clinicopathologic subtypes: (1) children (18 y of age or younger) presenting with severe anemia, nodular gastric mucosa, and isolated gastric disease; and (2) adults with chronic watery diarrhea that is associated with diffuse collagenous involvement of the gastrointestinal tract. However, notable exceptions exist...

Collagenous gastritis is a rare disease characterized by the subepithelial deposition of collagen bands thicker than 10 μm and the infiltration of inflammatory mononuclear cells in the lamina propria. Collagenous colitis and collagenous sprue have similar histological characteristics to collagenous gastritis and are thought to be part of the same disease entity. However, while collagenous colitis has become more common in the field of gastroenterology, presenting with clinical symptoms of chronic diarrhea in older patients, collagenous gastritis is rare...

Rhonda K Yantiss
Eosinophils are commonly detected in normal mucosal biopsies from all sites within the gastrointestinal tract where they are dispersed in the lamina propria and, to a lesser extent, in the epithelium. The distinction between the upper limit of normal and abnormally increased tissue eosinophils is not well defined. However, eosinophils that infiltrate the epithelium in more than occasional numbers, coalesce to form aggregates, or show extensive degranulation are always abnormal and raise a broad differential diagnosis...

Helicobacter pylori is the main aetiologic factor for chronic gastritis worldwide. The degree of inflammation and the evolution of this form of chronic gastritis can vary largely depending on bacterial virulence factors, host susceptibility factors and environmental conditions. Autoimmune gastritis is another cause of chronic inflammation in the stomach, which can occur in all age groups. This disease presents typically with vitamin B12 deficiency and pernicious anaemia. The presence of anti-parietal cell antibodies is highly specific for the diagnosis...

The cells that line the mucosa of the human gastrointestinal tract (GI, that is, oral cavity, oesophagus, stomach, small intestine, large intestine, and rectum) are constantly challenged by adverse micro-environmental factors, such as different pH, enzymes, and bacterial flora. With exception of the oral cavity, these microenvironments also contain remnant cocktails of secreted enzymes and bacteria from upper organs along the tract. The density of the GI bacteria varies, from 103/mL near the gastric outlet, to 1010/mL at the ileocecal valve, to 1011 to 1012/mL in the colon...

Collagenous gastritis is a rare condition defined histologically by a superficial subepithelial collagen layer. This study further characterizes the morphologic spectrum of collagenous gastritis by evaluating a multi-institutional series of 40 patients (26 female and 14 male). The median age at onset was 16 years (range 3-89 years), including 24 patients (60%) under age 18. Twelve patients (30%) had associated celiac disease, collagenous sprue, or collagenous colitis. Hematoxylin and eosin slides were reviewed in biopsies from all patients and tenascin, gastrin, eotaxin, and IgG4/IgG immunohistochemical stains were applied to a subset...

INTRODUCTION: Collagenous gastritis is a rare histopathologic disease. It is characterized by marked subepithelial collagen deposition with associated inflammatory infiltrate. It is considered an uncommon disease among the general population. Collagenous gastritis without colonic involvement is an extremely rare disease. It is not known to be associated with systemic lupus erythromatosis. This is the first report of this type of association. CASE PRESENTATION: We present a 47-year-old woman from southeast Asia with dyspepsia and mild anemia...

AIM: While collagenous colitis represents the most common form of the collagenous gastroenteritides, the collagenous entities affecting the proximal part of the gastrointestinal tract are much less recognized and possibly overlooked. The aim was to summarize the latest information through a systematic review of collagenous gastritis, collagenous sprue, and a combination thereof. METHOD: The search yielded 117 studies which were suitable for inclusion in the systematic review...
