[165] Maintaining a balanced diet with proper portion control can help manage symptoms of the disease. It is associated with macrophages' diminished ability to phagocytize MAP. 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. [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. [3] It also often begins after gastroenteritis. 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… It is not to be confused with, CS1 maint: DOI inactive as of November 2020 (, CS1 maint: multiple names: authors list (, CS1 maint: DOI inactive as of December 2020 (. [96] Adherent-invasive Escherichia coli (AIEC), are more common in people with CD,[97][98][96] have the ability to make strong biofilms compared to non-AIEC strains correlating with high adhesion and invasion indices[99][100] of neutrophils and the ability to block autophagy at the autolysosomal step, which allows for intracellular survival of the bacteria and induction of inflammation. [185], Crohn's may result in anxiety or mood disorders, especially in young people who may have stunted growth or embarrassment from fecal incontinence. It is characterised by periods of improvement followed by episodes when symptoms flare up. [215][216], Crohn's is common in parts of the world where helminthic colonisation is rare and uncommon in those areas where most people carry worms. There is no statistical significance between strictureplasty alone versus strictureplasty and resection in cases of duodenal involvement. [59] Also, immunomodulators and biologic agents used to treat this disease may promote developing extra-intestinal cancers. [143] Ferritin levels help assess if iron deficiency is contributing to the anemia. [1], Crohn's disease affects about 3.2 per 1,000 people in Europe and North America. There is usually an abrupt transition between unaffected tissue and the ulcer—a characteristic sign known as skip lesions. It usually reoccurs, although some people can remain disease-free for years or decades. [201] It also has a higher incidence in Ashkenazi Jews[1][204] and smokers. Prolonged use of corticosteroids has significant side-effects; as a result, they are, in general, not used for long-term treatment. [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. In these cases, re-operation rates were 31% and 27%, respectively, indicating that strictureplasty is a safe and effective treatment for selected people with duodenal involvement. 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. [44], Crohn's disease can also cause neurological complications (reportedly in up to 15%). [206] However, only slightly more women than men have Crohn's disease. It usually affects female children more severely than males. [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. Abdominal pain is often most severe in areas of the bowel with stenoses. [209], The incidence of Crohn's disease is increasing in Europe[210] and in newly industrialised countries. [209], The incidence of Crohn's disease is increasing in Europe[210] and in newly industrialised countries. All agree that severe anemia (hemoglobin under 10g/dL) should be treated with parenteral iron. However, due to the precedence of Crohn's name in the alphabet, it later became known in the worldwide literature as Crohn's disease. Guidelines vary as to how iron should be administered. [1] Other conditions that can present similarly include irritable bowel syndrome and Behçet's disease. Those who consume vegetable proteins appear to have a lower incidence of Crohn's disease. [211] For example, in Brazil, there has been an annual increase of 11% in the incidence of Crohn's disease since 1990. [14][15] It has historically been more common in the developed world. [45] The most common of these are seizures, stroke, myopathy, peripheral neuropathy, headache, and depression. [199] However, Crohn's disease is associated with a small increase in risk of small bowel and colorectal carcinoma (bowel cancer). [19], Some evidence supports the hypothesis that the bacterium Mycobacterium avium subspecies paratuberculosis (MAP) is a cause of Crohn's disease (see also Johne's disease). [7][69] Another theory is that the inflammation of Crohn's was caused by an overactive Th1 and Th17 cytokine response. [220][221], There is no good evidence that thalidomide or lenalidomide is useful to bring about or maintain remission. [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. [81] Diventa nostro ambasciatore e aggiungi la tua risposta. [37] This group of diseases is characterized by inflammation of one or more joints (arthritis) or muscle insertions (enthesitis). Other causes of anemia include medication used in treatment of inflammatory bowel disease, like azathioprine, which can lead to cytopenia, and sulfasalazine, which can also result in folate deficiency. This same gene may reduce innate and adaptive immunity in gastrointestinal tissue and impair the ability to resist infection by the MAP bacterium. It is common for people with Crohn's disease to try complementary or alternative therapy. [62][63], Crohn's disease can be problematic during pregnancy, and some medications can cause adverse outcomes for the fetus or mother. [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. 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. Crohn's is responsible for 10% of vesicoenteric fistulae, and is the most common cause of ileovesical fistulae. [134] [64], While the exact cause or causes are unknown, Crohn's disease seems to be due to a combination of environmental factors and genetic predisposition. paratuberculosis infection. [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]. A: Crohn's disease is a chronic condition that causes inflammation of lining of the digestive tract. [1] Diagnosis is based on a number of findings, including biopsy and appearance of the bowel wall, medical imaging, and description of the disease. 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 … Perianal discomfort may also be prominent in Crohn's disease. A disease of both the ileum (the last part of the small intestine that connects to the large intestine), and the large intestine, Ileocolic Crohn's accounts for fifty percent of cases. [1][2][18] Males and females are equally affected. The gene is responsible for making a protein, which collects and eliminates waste product in cells, and is also associated with Parkinson's disease. [5] It is less common in Asia and Africa. Anemia of chronic disease results in a normocytic anemia. 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. [105] Regional and temporal variations in those illnesses follow those associated with infection with the protozoan Blastocystis. In severe cases, an individual may have more than 20 bowel movements per day, and may need to awaken at night to defecate. Rarely autoimmune hemolysis may occur. 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. [47] Fungal infection such as candidiasis is also common, and people have a higher risk of cavities. Eating small meals frequently instead of big meals may also help with a low appetite. [1][2] Treatment options are intended to help with symptoms, maintain remission, and prevent relapse. [14][15] It has historically been more common in the developed world. Medication Individuals with moderate or severe symptoms of Crohn’s disease will typically receive steroid medication to reduce inflammation. Djurić Z, Šaranac L, Budić I, Pavlović V, Djordjević J. In some cases, however, it may not be possible to tell the difference, in which case the disease is classified as indeterminate colitis. [37] The symptoms of arthritis include painful, warm, swollen, stiff joints, and loss of joint mobility or function. [25] Flatulence, bloating, and abdominal distension are additional symptoms and may also add to the intestinal discomfort. [116] [180], Postsurgical recurrence of Crohn's disease is relatively common. Che cos’è la European Crohn’s and Colitis Organisation (ECCO)? [185], Crohn's may result in anxiety or mood disorders, especially in young people who may have stunted growth or embarrassment from fecal incontinence. Some people should follow a low fiber diet to control acute symptoms especially if fibrous foods cause symptoms. The utility of capsule endoscopy for this, however, is still uncertain. When symptoms are in remission, treatment enters maintenance, with a goal of avoiding the recurrence of symptoms. [181] Fewer lesions result in a lower grade. Other causes of anemia include medication used in treatment of inflammatory bowel disease, like azathioprine, which can lead to cytopenia, and sulfasalazine, which can also result in folate deficiency. It usually affects female children more severely than males. These neutrophils, along with mononuclear cells, may infiltrate the crypts, leading to inflammation (crypititis) or abscess (crypt abscess). [84], There was a prevailing view that Crohn's disease is a primary T cell autoimmune disorder; however, a newer theory hypothesizes that Crohn's results from an impaired innate immunity. [211], Inflammatory bowel diseases were described by Giovanni Battista Morgagni (1682–1771) and by Scottish physician T Kennedy Dalziel in 1913. [205], Crohn's disease begins most commonly in people in their teens and 20s, and people in their 50s through to their 70s. The "Rutgeert's score" is an endoscopic scoring system for post-operative disease recurrence in Crohn's disease. (ANSA) - PISA, 09 OTT - Arriva da Pisa la scoperta di un nuovo biomarcatore plasmatico, l'oncostatina M, per la terapia farmacologica del morbo di Crohn. Biopsy samples taken from the colons of all three patient groups were found to produce elevated levels of a serine protease. The gene is responsible for making a protein, which collects and eliminates waste product in cells, and is also associated with Parkinson's disease. 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. They remain useful for identifying anatomical abnormalities when strictures of the colon are too small for a colonoscope to pass through, or in the detection of colonic fistulae (in this case contrast should be performed with iodate substances). [212], Ileitis terminalis was first described by Polish surgeon Antoni Leśniowski in 1904, although it was not conclusively distinguished from intestinal tuberculosis. The gradual loss of blood from the gastrointestinal tract, as well as chronic inflammation, often leads to anemia, and professional guidelines suggest routinely monitoring for this. [215][216], Crohn's is common in parts of the world where helminthic colonisation is rare and uncommon in those areas where most people carry worms. [1][25][26][27] Visible bleeding in the feces is less common in Crohn's disease than in ulcerative colitis, but is not unusual. [2] Dietary microparticles, such as those found in toothpaste, have been studied as they produce effects on immunity, but they were not consumed in greater amounts in patients with Crohn's. [25][28][29], Symptoms caused by intestinal stenosis are also common in Crohn's disease. [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. Clubbing, a deformity of the ends of the fingers, may also be a result of Crohn's disease. [107][108][109], There is an apparent connection between Crohn's disease, Mycobacterium, other pathogenic bacteria, and genetic markers. Abdominal pain is often most severe in areas of the bowel with stenoses. Ileitis typically results in large-volume, watery feces, while colitis may result in a smaller volume of feces of higher frequency. Diets that include higher levels of fiber and fruit are associated with reduced risk, while diets rich in total fats, polyunsaturated fatty acids, meat, and omega-6 fatty acids may increase the risk of Crohn's. Certain lifestyle changes can reduce symptoms, including dietary adjustments, elemental diet, proper hydration, and smoking cessation. [201][202] Crohn's disease is more common in northern countries, and with higher rates still in the northern areas of these countries. [203] The incidence of Crohn's disease is thought to be similar in Europe but lower in Asia and Africa. [110][111] In many individuals, genetic factors predispose individuals to Mycobacterium avium subsp. [84], There was a prevailing view that Crohn's disease is a primary T cell autoimmune disorder; however, a newer theory hypothesizes that Crohn's results from an impaired innate immunity. Biopsies may also show chronic mucosal damage, as evidenced by blunting of the intestinal villi, atypical branching of the crypts, and a change in the tissue type (metaplasia). ", "A systematic review of systematic reviews of homeopathy", "Evidence Check 2: Homeopathy - Science and Technology Committee", "Cannabis for the treatment of Crohn's disease", "Meta-analysis: colorectal and small bowel cancer risk in patients with Crohn's disease", "Epidemiology of inflammatory bowel disease in a defined northern California population", "Incidence of inflammatory bowel disease across Europe: is there a difference between north and south? It is not to be confused with, CS1 maint: DOI inactive as of November 2020 (, CS1 maint: multiple names: authors list (, CS1 maint: DOI inactive as of December 2020 (. These neutrophils, along with mononuclear cells, may infiltrate the crypts, leading to inflammation (crypititis) or abscess (crypt abscess). [207] Parents, siblings or children of people with Crohn's disease are 3 to 20 times more likely to develop the disease. [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%. [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. [1][13] Tobacco smokers are twice as likely to develop Crohn's disease as nonsmokers. The gradual loss of blood from the gastrointestinal tract, as well as chronic inflammation, often leads to anemia, and professional guidelines suggest routinely monitoring for this. Alcuni fattori ambientali egualmente sono associati con il morbo di Crohn. Qui puoi vedere la definizione del Morbo di Crohn e sapere in cosa consiste Non ci sono ancora risposte per questa domanda. 2017 Feb 25;20(2):147-155. doi: 10.1007/s40477-017-0243-8. [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). [69] In this view, the chronic inflammation of Crohn's is caused when the adaptive immune system tries to compensate for a deficient innate immune system. A disease of both the ileum (the last part of the small intestine that connects to the large intestine), and the large intestine, Ileocolic Crohn's accounts for fifty percent of cases. [147][148][149][150], Low serum levels of vitamin D are associated with Crohn's disease. As 30% of Crohn's disease involves only the ileum,[1] cannulation of the terminal ileum is required in making the diagnosis. Crohn’s disease is an inflammatory bowel disease that causes chronic inflammation of the gastrointestinal tract. [115], The increased incidence of Crohn's in the industrialized world indicates an environmental component. [121][122] The use of doxycycline has also been associated with increased risk of developing inflammatory bowel diseases. Bosn J Basic Med Sci. [47], Crohn's disease can lead to several mechanical complications within the intestines, including obstruction,[52] fistulae,[53] and abscesses. Symptoms often include abdominal pain, diarrhea (which may be bloody if inflammation is severe), fever, abdominal distension, and weight loss. [19], Some evidence supports the hypothesis that the bacterium Mycobacterium avium subspecies paratuberculosis (MAP) is a cause of Crohn's disease (see also Johne's disease). Besides other, problems include a limitation in possible daily resorption and an increased growth of intestinal bacteria. [1] Ulceration is an outcome seen in highly active disease. [33] As it may manifest at the time of the growth spurt in puberty, up to 30% of children with Crohn's disease may have retardation of growth. Some[177] advise parenteral iron as first line as it works faster, has fewer gastrointestinal side effects, and is unaffected by inflammation reducing enteral absorption. [203] The incidence of Crohn's disease is thought to be similar in Europe but lower in Asia and Africa. [4] Irritable bowel syndrome is excluded when there are inflammatory changes. Crawford JM. In some cases, however, it may not be possible to tell the difference, in which case the disease is classified as indeterminate colitis. Trials of extracts from the worm Trichuris suis showed promising results when used in people with IBD. "FDA Approves Cimzia to Treat Crohn's Disease", "Natalizumab for induction of remission in Crohn's disease", "Anti-IL-12/23p40 antibodies for induction of remission in Crohn's disease", "Guidelines for the management of iron deficiency anaemia", "Guidelines on the diagnosis and management of iron deficiency and anemia in inflammatory bowel diseases", "Surgical recurrence in Crohn's disease: Are we getting better? Such individuals may require oral supplements to increase their caloric intake, or in severe cases, total parenteral nutrition (TPN). [146] Furthermore, increasing amounts and levels of serological antibodies such as ASCA, antilaminaribioside [Glc(β1,3)Glb(β); ALCA], antichitobioside [GlcNAc(β1,4)GlcNAc(β); ACCA], antimannobioside [Man(α1,3)Man(α)AMCA], antiLaminarin [(Glc(β1,3))3n(Glc(β1,6))n; anti-L] and antichitin [GlcNAc(β1,4)n; anti-C] associate with disease behavior and surgery, and may aid in the prognosis of Crohn's disease. Adequately controlled, Crohn's disease may not significantly restrict daily living. [37][39][40] Erythema nodosum is due to inflammation of the underlying subcutaneous tissue, and is characterized by septal panniculitis. Crohn's disease is an inflammatory bowel disease (IBD). [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). They may have specific dietary intolerances (not allergies). [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. [102] AIEC strains replicate extensively inside macrophages inducing the secretion of very large amounts of TNF-α. [1] It tends to start in the teens and twenties, though it can occur at any age. Smoking increases the risk of the return of active disease (flares). [42] Involvement of the duodenum and jejunum can impair the absorption of many other nutrients including folate. With treatment, most people achieve a healthy weight, and the mortality rate for the disease is relatively low. It can vary from being benign to very severe, and people with CD could experience just one episode or have continuous symptoms. [64], While the exact cause or causes are unknown, Crohn's disease seems to be due to a combination of environmental factors and genetic predisposition. [137], CT and MRI scans are useful for evaluating the small bowel with enteroclysis protocols. These categorizations formalized in the Vienna classification of the disease. [67] Crohn's is the first genetically complex disease in which the relationship between genetic risk factors and the immune system is understood in considerable detail.
