Nausea, vomiting, and fever may occur. Symptoms begin within 48 hours of ingestion, and quickly self-resolve or become chronic.
What does terminal ileum and colon mean?
The terminal ileum, located in the cecum,or caecum,connects the small intestine to the large. The terminal ileum is part of the digestive system. The most distant portion of the small intestine, it aids in digestion by absorbing materials not previously digested by the jejunum, the middle portion of the small intestine.

What is terminal ileitis?
Ileitis also called terminal ileitis, is an inflammation of the ileum, the last part of the small intestine that joins the large intestine. Ileitis symptoms include weight loss, diarrhea, cramping or pain in the abdomen, or fistulas (abnormal channels that develop between parts of the intestine). Ileitis can be caused by a wide variety of other diseases, Crohn’s disease being the most common 1). Other causes of ileitis include infectious diseases, effects of non-steroidal anti-inflammatory drugs (NSAIDs), spondyloarthropathies, vasculitides, ischemia, neoplasms, medication-induced, eosinophilic enteritis, abnormal growths, sarcoidosis, amyloidosis, and others 2).
Why is ileitis important?
Delayed growth or sexual development, in children. The diagnosis of the cause of ileitis is of paramount importance because misdiagnosis may result in critical delays or errors in management.
What causes ischemic ileitis?
Other conditions aside from vasculitis cause ischemic ileitis. An important cause is nonocclusive mesenteric ischemia (nonocclusive mesenteric ischemia) as a result of splanchnic hypoperfusion and vasospasm observed predominantly in elderly patients with atherosclerotic vascular disease in the setting of low-flow states (eg, shock, heart failure, drugs such as cocaine). The microvasculature is patent in nonocclusive mesenteric ischemia, but blood flow is inadequate to meet intestinal tissue demands. Because the ileocolic branches are the longest branches of the superior mesenteric artery, the ileocecal region is most susceptible to ischemia from poor perfusion 50).
What are the most common causes of ileitis?
Vasculitides that are primary to the intestine or occur secondary to systemic vasculitis represent a rare cause of ileitis. The most common vasculitides with gastrointestinal involvement include the medium-sized vessel vasculitides of systemic lupus erythematosus and polyarteritis nodosa, and the small vessel vasculitides of Henoch-Schönlein purpura and Behçet’s disease. Visceral vasculitis presents with abdominal pain, nausea, vomiting, diarrhea, and gastrointestinal bleeding. Small-vessel or leukocytoclastic vasculitis is characterized by mucosal ischemia, whereas vasculitis involving medium-size or larger vessels may more likely result in transmural involvement, leading to peritoneal findings or perforation. Other serious complications include obstruction, protein-losing enteropathy, and intussusception. Moreover, patients with acquired antiphospholipid antibodies and systemic lupus erythematosus or related disorders are at increased risk for mesenteric artery thrombosis and subsequent bowel infarction 47).

What is terminal ileitis?
Terminal ileitis (TI) is an inflammatory condition of the terminal portion of the ileum described in medical literature since a long time ago. It may occur acutely with right lower quadrant pain followed or not by diarrhea, or exhibit chronic obstructive symptoms and bleeding [1-4].
What is TI in medical terms?
In 1936, the Epitome of Current Medical Literature [5] described the TI or ileitis terminalis and pointed that this condition recognized by Crohn in 1932 should be described as a new disease. In that Epitome, it is possible to read that “ileitis is a non-specific inflammation of the terminal portion of the ileum which sometimes spreads to the cecum causes ulceration of the intestinal mucosa, thickening and retraction of the intestinal wall... The diagnosis is based on the exclusion of specific infective processes in the ileum such as ileo-cecal tuberculosis and actinomycosis ”
What is TI in UC?
When TI is observed in UC, the name used is BWI that refers to an inflammation process in the distal few centimeters of terminal ileum. This inflammation condition of the ileum occurs due to reduced ileocecal valve function in severe UC (when present, may indicate the differential diagnosis of CD), allowing for retrograde flow of colonic content and inflammation of the ileum. There is stasis that occurs from inflammation-induced colonic hypomotility, or continuous extension of inflammation from the colon. This ileitis is normally mild and is related to neutrophilic inflammation in the lamina propria, focal cryptitis/crypt abscesses and, rarely, superficial mucosal erosions. Occasionally it may only exhibit mucosal injury, as villous blunting and regenerative epithelial changes. It can be differentiated from CD by the large length of involved small bowel separated by skip regions in the cecum or distal ileum, higher inflammatory process and mucosal injury in the ileum, transmural ileal inflammation and neural hyperplasia, and mucous gland metaplasia of the ileal mucosa. Literature also reports that ileal changes in UC may reach 17%. Normally, the severity of ileum inflammation parallels the severity of the colonic activity, commonly with pancolitis and cecal involvement [3, 34-36].
How are enterocolitis microorganisms acquired?
These microorganisms are mainly acquired more commonly by ingestion of contaminated water or food and the most frequent clinical aspect is the presence of enterocolitis with pain, diarrhea, low-grade fever, mucosal ulceration, neutrophil invasion, thickening of the ileal wall (leading to perforation), rectal bleeding, reactive polyarthritis and septicemia. Diagnosis is by stool culture and colonoscopy with biopsy. Endoscopic patterns include aphthoid lesions of the cecum and TI with round or oval elevations with ulcerations that are mostly uniform in size and shape, in contrast to CD. The formation of fistula and fibrotic stenosis appears commonly in CD [4, 60-62].
What is the response of the innate immune system to pathogens?

Is ileitis a symptom of MD?
Many studies have shown the association among MD and CD, and some authors postulate that ileitis is attributable to acid-secreting gastric heterotopia. Complications of MD are more frequent in male and younger individuals. Bleeding occurs more frequently in adult males and in children, mainly younger than 4 years of age, and it occurs mainly as obstruction [43-45].
What causes ileocolitis?
Infiltrative causes of ileitis include a number of diseases: eosinophilic gastroenteritis (EG), systemic mastocytosis, sarcoidosis and endometriosis. The endoscopic findings of EG vary from normal mucosa to mild erythema, nodularity and ulceration. Diffuse enteritis with complete loss of villi, submucosal edema, and fibrosis may be present. Multiple biopsies are required because of the patchy nature of the disease, and full-thickness surgical biopsies may be necessary if disease is confined to the muscle layer. CD can usually be differentiated by the typical architectural distortion that is not found in EG. Eosinophilic ileocolitis may be more common than originally thought and the counting of high-power microscopic fields for eosinophils may be a useful way of distinguishing eosinophilic ileocolitis from CD ileocolitis. Rarely, CD is associated with peripheral eosinophilia and/or an eosinophil-rich tissue infiltrate [20,21].
What is Yersinia enterocolitica?
Yersinia enterocoliticainfection occurs mainly in the TI and causes mucosal ulceration, neutrophil invasion, and thickening of the ileal wall. Distal ileal and cecal involvement predominates, and patients present with symptoms of small-bowel obstruction and a tender abdominal mass. The diagnosis is made most directly by colonoscopy with biopsy and culture. Endoscopic features of Yersiniainclude aphthoid lesions of the cecum and TI with round or oval elevations with ulcerations. The ulcers are mostly uniform in size and shape, in contrast to CD [8]. Mycobacterium avium-intracellulare complex infection occurs in advanced stages of HIV infection and in other immunocompromized states; it usually manifests as a systemic infection with diarrhea, abdominal pain, weight loss, fever, and malabsorption. Diagnosis is established by culture of mucosal biopsies. Disseminated histoplasmosis can also involve the ileocecal area. TI can be affected in other intestinal infections caused by Salmonella spp., cytomegalovirus. Ileitis was described in infection with Clostridium difficile(BI/NAP1/027 strains [9]), typical pseudomembranes were seen on ileal mucosa.
What is the cause of TI?
Chronic inflammation in the terminal ileum (TI) suggests a cause for the patient’s symptoms, especially when the clinical suspicion is Crohn’s disease (CD). Clinic, laboratory, endoscopic, histopathological evaluation of patients is required for the diagnosis of CD. The most frequent localization of CD is the TI. There are many other diseases affecting the TI. Non-steroidal antiinflammatory drug (NSAID) intake as well as other pathological conditions such as lymphoid hyperplasia, intestinal infections, lymphoma, infections and ulcerative colitis (UC) can mimic CD terminal ileitis.
What is the significance of ileocolonoscopy for sarcoidosis?
In patients with sarcoidosis and suspected ileitis, ileocolonoscopy with biopsy revealing noncaseating granulomas containing multinucleated giant cells is nearly diagnostic. Precise interpretation of ileal biopsies is crucial because CD, mycobacterial infections, histoplasmosis and lymphoma are granulomatous conditions that mimic sarcoidosis.

Why are malignant tumors of the small intestine easy to misdiagnose?
Primary malignant tumors of the small intestine are easy to be misdiagnosed because of nonspecific symptoms and signs and the limited examination methods. In the ileum, malignant lymphoma constitutes about half of all malignancies (48.3% in this group), followed by adenocarcinoma, leiomyosarcoma and carcinoid tumors.
Is focal lymphoid hyperplasia a terminal ileitis?
Focal lymphoid hyperplasia of the TI is a rare cause of terminal ileitis. In 1996 the case of a 13-year-old boy was described with a stricture of the TI that was diagnosed as CD on barium follow through. This patient had no response to steroid therapy and the boy required resection of TI. Histology findings of TI showed focal lymphoid hyperplasia and not CD [10].

Is ileitis associated with spondylarthropathy?
Ileitis associated with spondylarthropathy or nonsteroidal anti- inflammatory drugs is typically subclinical and often escapes detection unless further testing is warranted by symptoms. In a minority of patients with long-standing Crohn's ileitis, the recrudescence of symptoms may represent a neoplasm involving the ileum.
