crohn's disease cos'è

Itchiness or pain around the anus may be suggestive of inflammation, fistulization or abscess around the anal area[1] or anal fissure. These neutrophils, along with mononuclear cells, may infiltrate the crypts, leading to inflammation (crypititis) or abscess (crypt abscess). [104] Experimental introduction of the serine protease into mice has been found to produce widespread pain associated with irritable bowel syndrome, as well as colitis, which is associated with all three diseases. [45] The most common of these are seizures, stroke, myopathy, peripheral neuropathy, headache, and depression. [55], Crohn's disease also increases the risk of cancer in the area of inflammation. [167], Medications used to treat the symptoms of Crohn's disease include 5-aminosalicylic acid (5-ASA) formulations, prednisone, immunomodulators such as azathioprine (given as the prodrug for 6-mercaptopurine), methotrexate,[168] infliximab, adalimumab,[26] certolizumab,[169] vedolizumab, ustekinumab,[170] and natalizumab. [183] Diarrhea is the main symptom, but others may include weight loss, cramping, bloating, and heartburn. [25] Although the association is greater in the context of ulcerative colitis, Crohn's disease may also be associated with primary sclerosing cholangitis, a type of inflammation of the bile ducts.[30]. [83], Crohn's has been linked to the gene LRRK2 with one variant potentially increasing the risk of developing the disease by 70%, while another lowers it by 25%. [82] Genome-wide association studies have shown that Crohn's disease is genetically linked to coeliac disease. [164] Some find relief in eliminating casein (a protein found in cow's milk) and gluten (a protein found in wheat, rye and barley) from their diets. A complete blood count may reveal anemia, which commonly is caused by blood loss leading to iron deficiency or by vitamin B12 deficiency, usually caused by ileal disease impairing vitamin B12 absorption. [54] Obstruction typically occurs from strictures or adhesions that narrow the lumen, blocking the passage of the intestinal contents. [55], Crohn's disease also increases the risk of cancer in the area of inflammation. [116] Come verrà somministrato Entyvio 4. Crohn’s treatment aims to reduce the inflammation in the intestine and to help manage the symptoms of Crohn’s disease, such as weight-loss and abdominal pain. As a result, a barium follow-through X-ray, wherein barium sulfate suspension is ingested and fluoroscopic images of the bowel are taken over time, is useful for looking for inflammation and narrowing of the small bowel. [68] Each individual risk mutation makes a small contribution to the overall risk of Crohn's (approximately 1:200). [61], The major significant complications of Crohn's disease include bowel obstruction, abscesses, free perforation, and hemorrhage, which in rare cases may be fatal. [137], CT and MRI scans are useful for evaluating the small bowel with enteroclysis protocols. [37] Individuals with osteoporosis are at increased risk of bone fractures. [37] The arthritis in Crohn's disease can be divided into two types. CDAI : Crohn's disease activity index IBDQ : inflammatory bowel disease questionnaire *p<0.05 (Kanai T et al., 2000 ‚æ‚è‰ü•Ï) 9) 最近,ク ローン病で最も注目されているサイト カインはTNF-α である10).TNF-α … When symptoms are in remission, treatment enters maintenance, with a goal of avoiding the recurrence of symptoms. This same gene may reduce innate and adaptive immunity in gastrointestinal tissue and impair the ability to resist infection by the MAP bacterium. In some cases of SBS, intestinal transplant surgery may be considered; though the number of transplant centres offering this procedure is quite small and it comes with a high risk due to the chance of infection and rejection of the transplanted intestine. Test subjects were reintroduced to harmless parasites, with positive response. Abscesses are walled-off concentrations of infection, which can occur in the abdomen or in the perianal area. [203] The incidence of Crohn's disease is thought to be similar in Europe but lower in Asia and Africa. A study of heritability and the influence of smoking", "The burden of inflammatory bowel disease in Europe", "Antoni Lésniowski and his contribution to regional enteritis (Crohn's disease)", "Use of antibiotics in the treatment of Crohn's disease", "Translatability of helminth therapy in inflammatory bowel diseases", "Coronado Biosciences Announces Top-Line Results From Its TRUST-I Phase 2 Clinical Trial of TSO for the Treatment of Crohn's Disease", "Coronado Biosciences Announces Independent Data Monitoring Committee Recommendation to Discontinue Falk Phase 2 Trial of TSO in Crohn's Disease", "Thalidomide and thalidomide analogues for maintenance of remission in Crohn's disease", "ACG Clinical Guideline: Management of Crohn's Disease in Adults", National Society for Colitis and Crohn's Disease, List of people diagnosed with ulcerative colitis, Esophageal intramural pseudodiverticulosis, Small bowel bacterial overgrowth syndrome, Hereditary benign intraepithelial dyskeratosis, Neuralgia-inducing cavitational osteonecrosis, https://en.wikipedia.org/w/index.php?title=Crohn%27s_disease&oldid=993692632, Steroid-responsive inflammatory conditions, Articles with dead external links from December 2019, Articles with permanently dead external links, CS1 maint: DOI inactive as of November 2020, CS1 maint: DOI inactive as of December 2020, Articles with dead external links from July 2017, Articles with unsourced statements from July 2020, Articles containing potentially dated statements from 2017, All articles containing potentially dated statements, Wikipedia medicine articles ready to translate, Creative Commons Attribution-ShareAlike License, Crohn disease, Crohn syndrome, granulomatous enteritis, regional enteritis, Leśniowski-Crohn disease, The three most common sites of intestinal involvement in Crohn's disease, Patchy areas of inflammation (skip lesions), Deep geographic and serpiginous (snake-like), A 2006 survey in Germany found that about half of people with IBD used some form of alternative medicine, with the most common being, There are contradicting studies regarding the effect of, This page was last edited on 11 December 2020, at 23:58. [78] Another study theorized that the human immune system traditionally evolved with the presence of parasites inside the body, and that the lack thereof due to modern hygiene standards has weakened the immune system. People with Crohn's often also have issues with small bowel bacterial overgrowth syndrome, which can produce micronutrient deficiencies. As a result, the cholesterol/bile ratio increases in the gallbladder, resulting in an increased risk for gallstones. 2018 Aug 1;18(3):211-216. doi: 10.17305/bjbms.2018.2792. [131] The disease can attack any part of the digestive tract, from mouth to anus. Crohn's disease is a type of inflammatory bowel disease (IBD) that may affect any segment of the gastrointestinal tract from the mouth to the anus. The granulomas of Crohn's disease do not show "caseation", a cheese-like appearance on microscopic examination characteristic of granulomas associated with infections, such as tuberculosis. Those who consume vegetable proteins appear to have a lower incidence of Crohn's disease. Usefulness of panoramic 344 -viewing in Crohn's disease capsule endoscopy : a proof of concept pilot study with the novel PillCam Crohn's system / G.E. The "Rutgeert's score" is an endoscopic scoring system for post-operative disease recurrence in Crohn's disease. Inflammation in different areas of the intestinal tract can affect the quality of the feces. [85] The later hypothesis describes impaired cytokine secretion by macrophages, which contributes to impaired innate immunity and leads to a sustained microbial-induced inflammatory response in the colon, where the bacterial load is high. Blood transfusion should be reserved for those who are cardiovascularly unstable, due to its relatively poor safety profile, lack of long term efficacy, and cost. Later that year, he, along with colleagues Leon Ginzburg and Gordon Oppenheimer, published the case series as "Regional ileitis: a pathologic and clinical entity". The Crohn's and Colitis Foundation of America cites this number as approx 149:100,000; NIH cites 28 to 199 per 100,000. It can vary from being benign to very severe, and people with CD could experience just one episode or have continuous symptoms. [22] The usual onset is in the teens and twenties, but can occur at any age. Crohn's is associated with an increased intake of animal protein, milk protein, and an increased ratio of omega-6 to omega-3 polyunsaturated fatty acids. [113][114], There is a tentative association between Candida colonization and Crohn's disease. [205], Crohn's disease begins most commonly in people in their teens and 20s, and people in their 50s through to their 70s. [175][176][177] Adequate disease control usually improves anemia of chronic disease, but iron deficiency may require treatment with iron supplements. [201] It also has a higher incidence in Ashkenazi Jews[1][204] and smokers. In Cotran RS, Kumar V, Robbins SL. [10] The exact underlying immune problem is not clear; however, it may be an immunodeficiency state. The "Rutgeert's score" is an endoscopic scoring system for post-operative disease recurrence in Crohn's disease. [174] The long term safety and effectiveness of monoclonal antibody treatment is not known. [37][39][40] Erythema nodosum is due to inflammation of the underlying subcutaneous tissue, and is characterized by septal panniculitis. La European Crohn’s and Colitis Organisation è la più grande associazione al mondo di specialisti in Malattie Infiammatorie Intestinali (in inglese IBD, Inflammatory Bowel Disease), e … [147][148][149][150], Low serum levels of vitamin D are associated with Crohn's disease. Disease in the small bowel is particularly difficult to diagnose, as a traditional colonoscopy allows access to only the colon and lower portions of the small intestines; introduction of the capsule endoscopy[129] aids in endoscopic diagnosis. [209], The incidence of Crohn's disease is increasing in Europe[210] and in newly industrialised countries. Alternatives include aminosalicylates alone, though only a minority are able to maintain the treatment, and many require immunosuppressive drugs. After the first resection, another resection may be necessary within five years. [200], The percentage of people with Crohn's disease has been determined in Norway and the United States and is similar at 6 to 7.1:100,000. Come conservare Entyvio 6. Most people with Crohn's live a normal lifespan. After the first surgery, Crohn's usually comes back at the site where the diseased intestine was removed and the healthy ends were rejoined; it can also come back in other locations. [175][176][177] Adequate disease control usually improves anemia of chronic disease, but iron deficiency may require treatment with iron supplements. [217][218][219] However these trials (TRUST -I & TRUST -II) failed in Phase 2 clinical trials and were then discontinued after consistent failure in both North America and Europe. L’organo più colpito è l’intestino tenue (70% dei casi), soprattutto l’ileo terminale. In some cases, however, it may not be possible to tell the difference, in which case the disease is classified as indeterminate colitis. [205], Crohn's disease begins most commonly in people in their teens and 20s, and people in their 50s through to their 70s. [135] A "cobblestone"-like appearance is seen in approximately 40% of cases of Crohn's disease upon colonoscopy, representing areas of ulceration separated by narrow areas of healthy tissue. [164] Some find relief in eliminating casein (a protein found in cow's milk) and gluten (a protein found in wheat, rye and barley) from their diets. [117] Isotretinoin is associated with Crohn's. [38], Crohn's disease may also involve the skin, blood, and endocrine system. [1] Bloody bowel movements are usually intermittent, and may be bright or dark red in color. Certain characteristic features of the pathology seen point toward Crohn's disease; it shows a transmural pattern of inflammation, meaning the inflammation may span the entire depth of the intestinal wall. [116] [88], It is hypothesised that maintenance of commensal microorganism growth in the GI tract is dysregulated, either as a result or cause of immune dysregulation. For example, one association is with mutations in the XBP1 gene, which is involved in the unfolded protein response pathway of the endoplasmic reticulum. A food diary may help with identifying foods that trigger symptoms. "The Gastrointestinal tract, Chapter 17". [2] The disease was named after gastroenterologist Burrill Bernard Crohn, who in 1932, together with two colleagues at Mount Sinai Hospital in New York, described a series of patients with inflammation of the terminal ileum of the small intestine, the area most commonly affected by the illness. This same gene may reduce innate and adaptive immunity in gastrointestinal tissue and impair the ability to resist infection by the MAP bacterium. [47] Signs of anemia such as pallor and angular cheilitis or glossitis are also common. [164], Acute treatment uses medications to treat any infection (normally antibiotics) and to reduce inflammation (normally aminosalicylate anti-inflammatory drugs and corticosteroids). Consultation with an obstetrician and gastroenterologist about Crohn's disease and all medications facilitates preventive measures. Più raramente interessa anche altre parti del tratto gastrointestinale (duodeno, cieco, stomaco ed esofago). For example, individuals with Crohn's disease involving the small bowel are at higher risk for small intestinal cancer. Some people should follow a low fiber diet to control acute symptoms especially if fibrous foods cause symptoms. Because colonoscopy and gastroscopy allow direct visualization of only the terminal ileum and beginning of the duodenum, they cannot be used to evaluate the remainder of the small intestine. È caratterizzata da ulcere intestinali, spesso alternate a tratti di intestino sano, e, se non curata adeguatamente, può portare a complicanze quali stenosi (restringimenti intestinali) o fistole che possono richiedere un intervento chirurgico, sebbe… [1] While surgery should be used as little as possible, it is necessary to address some abscesses, certain bowel obstructions, and cancers. [123][124][125] In one large retrospective study, patients who were prescribed doxycycline for their acne had a 2.25-fold greater risk of developing Crohn's disease.[124]. Smoking may worsen symptoms, and stopping is recommended. [37] This group of diseases is characterized by inflammation of one or more joints (arthritis) or muscle insertions (enthesitis). Erythema nodosum is the most common type of skin problem, occurring in around 8% of people with Crohn's disease, producing raised, tender red nodules usually appearing on the shins. [112], Still, this relationship between specific types of bacteria and Crohn's disease remains unclear. [3] The introduction of hormonal contraception in the United States in the 1960s is associated with a dramatic increase in incidence, and one hypothesis is that these drugs work on the digestive system in ways similar to smoking. Autoimmune hemolytic anemia, a condition in which the immune system attacks the red blood cells, is also more common in Crohn's disease and may cause fatigue, a pale appearance, and other symptoms common in anemia. [199] However, Crohn's disease is associated with a small increase in risk of small bowel and colorectal carcinoma (bowel cancer). [201][202] Crohn's disease is more common in northern countries, and with higher rates still in the northern areas of these countries. [89][90], A number of studies have suggested a causal role for Mycobacterium avium subspecies paratuberculosis (MAP), which causes a similar disease, Johne's disease, in cattle. [173] Biological therapies are medications used to avoid long-term steroid use, decrease inflammation, and treat people who have fistulas with abscesses. [1] Bowel obstruction may occur as a complication of chronic inflammation, and those with the disease are at greater risk of colon cancer and small bowel cancer. Guidelines vary as to how iron should be administered. This leads to the development of excessive watery diarrhea. [147][148][149][150], Low serum levels of vitamin D are associated with Crohn's disease. [151], The most common disease that mimics the symptoms of Crohn's disease is ulcerative colitis, as both are inflammatory bowel diseases that can affect the colon with similar symptoms. As 30% of Crohn's disease involves only the ileum,[1] cannulation of the terminal ileum is required in making the diagnosis. ovviamente è esclusa la combinazione in cui tutte e tre le parti sono presenti. Crohn's disease can be both painf… [1] Bloody bowel movements are usually intermittent, and may be bright or dark red in color. [164] Treatment for Crohn's disease is only when symptoms are active and involve first treating the acute problem, then maintaining remission. [4] Celiac disease cannot be excluded if specific antibodies (anti-transglutaminase antibodies) are negative,[157][158] nor in absence of intestinal villi atrophy.[159][160]. [220][221], There is no good evidence that thalidomide or lenalidomide is useful to bring about or maintain remission. On occasion, the colonoscopy can travel past the terminal ileum, but it varies from person to person. Contenuto della 1. Fecal consistency may range from solid to watery. It usually develops in those patients who have had half or more of their small intestines removed. Inflammatory disease (or nonstricturing, nonpenetrating disease) causes inflammation without causing strictures or fistulae.[132][133]. [42] Involvement of the duodenum and jejunum can impair the absorption of many other nutrients including folate. [34] Fever may also be present, though fevers greater than 38.5 °C (101.3 °F) are uncommon unless there is a complication such as an abscess. [123][124][125] In one large retrospective study, patients who were prescribed doxycycline for their acne had a 2.25-fold greater risk of developing Crohn's disease.[124]. [86][87], In 2007, the ATG16L1 gene was implicated in Crohn's disease, which may induce autophagy and hinder the body's ability to attack invasive bacteria. [7][9] While Crohn's is an immune-related disease, it does not appear to be an autoimmune disease (in that the immune system is not being triggered by the body itself). J Ultrasound. A fistula can develop between two loops of bowel, between the bowel and bladder, between the bowel and vagina, and between the bowel and skin. [166] Fatigue can be helped with regular exercise, a healthy diet, and enough sleep. [44], Crohn's disease can also cause neurological complications (reportedly in up to 15%). A colonoscopy is the best test for making the diagnosis of Crohn's disease, as it allows direct visualization of the colon and the terminal ileum, identifying the pattern of disease involvement. During a colonoscopy, biopsies of the colon are often taken to confirm the diagnosis. [1] Stopping smoking is recommended in people with Crohn's disease. [213] In Poland, it is still called Leśniowski-Crohn's disease (Polish: choroba Leśniowskiego-Crohna). [42][43] The most common is iron deficiency anemia[42] from chronic blood loss, reduced dietary intake, and persistent inflammation leading to increased hepcidin levels, restricting iron absorption in the duodenum. Alcuni fattori ambientali egualmente sono associati con il morbo di Crohn. Anemia of chronic disease results in a normocytic anemia. A food diary may help with identifying foods that trigger symptoms. As a result, a barium follow-through X-ray, wherein barium sulfate suspension is ingested and fluoroscopic images of the bowel are taken over time, is useful for looking for inflammation and narrowing of the small bowel. [178] Surgery may also be required for complications such as obstructions, fistulas, or abscesses, or if the disease does not respond to drugs. [165] Maintaining a balanced diet with proper portion control can help manage symptoms of the disease. [46] Other findings may include diffuse or nodular swelling of the mouth, a cobblestone appearance inside the mouth, granulomatous ulcers, or pyostomatitis vegetans. [1] Among children, growth failure is common. [31] Fecal incontinence may accompany perianal Crohn's disease. It is important to differentiate these diseases, since the course of the diseases and treatments may be different. [45], Recurrent aphthous ulcers are common; however, it is not clear whether this is due to Crohn's disease or simply that they are common in the general population. There is no statistical significance between strictureplasty alone versus strictureplasty and resection in cases of duodenal involvement. [37] The arthritis may also involve the spine, leading to ankylosing spondylitis if the entire spine is involved, or simply sacroiliitis if only the sacroiliac joint is involved. Most people with Crohn's live a normal lifespan. [78] Another study theorized that the human immune system traditionally evolved with the presence of parasites inside the body, and that the lack thereof due to modern hygiene standards has weakened the immune system. [217][218][219] However these trials (TRUST -I & TRUST -II) failed in Phase 2 clinical trials and were then discontinued after consistent failure in both North America and Europe. It usually develops in those patients who have had half or more of their small intestines removed. A: Crohn's disease is a chronic condition that causes inflammation of lining of the digestive tract.

[62][63], Crohn's disease can be problematic during pregnancy, and some medications can cause adverse outcomes for the fetus or mother. [37], Crohn's disease is associated with a type of rheumatologic disease known as seronegative spondyloarthropathy. There is no statistical significance between strictureplasty alone versus strictureplasty and resection in cases of duodenal involvement. Clubbing, a deformity of the ends of the fingers, may also be a result of Crohn's disease. Endoscopic biopsy showing granulomatous inflammation of the colon in a case of Crohn's disease. [176], Crohn's cannot be cured by surgery, as the disease eventually recurs, though it is used in the case of partial or full blockage of the intestine. Abdominal pain is often most severe in areas of the bowel with stenoses. [15][16] Inflammatory bowel disease resulted in 47,400 deaths in 2015,[17] and those with Crohn's disease have a slightly reduced life expectancy. [36] Inflammation of the interior portion of the eye, known as uveitis, can cause blurred vision and eye pain, especially when exposed to light (photophobia). There is usually an abrupt transition between unaffected tissue and the ulcer—a characteristic sign known as skip lesions. Other guidelines[176] advise oral iron as first line with parenteral iron reserved for those that fail to adequately respond as oral iron is considerably cheaper. Erythema nodosum is the most common type of skin problem, occurring in around 8% of people with Crohn's disease, producing raised, tender red nodules usually appearing on the shins. Therapeutic role of methotrexate in pediatric Crohn's disease. Autoimmune hemolytic anemia, a condition in which the immune system attacks the red blood cells, is also more common in Crohn's disease and may cause fatigue, a pale appearance, and other symptoms common in anemia. It is associated with macrophages' diminished ability to phagocytize MAP. [37] Individuals with osteoporosis are at increased risk of bone fractures. Bosn J Basic Med Sci. Certain lifestyle changes can reduce symptoms, including dietary adjustments, elemental diet, proper hydration, and smoking cessation. [211] For example, in Brazil, there has been an annual increase of 11% in the incidence of Crohn's disease since 1990. La malattia di Crohn è una condizione rara che colpisce il tratto digestivo e le viscere del cane. [1] Diagnosis is based on a number of findings, including biopsy and appearance of the bowel wall, medical imaging, and description of the disease.
