Role of esophagogastroduodenoscopy in the initial assessment of children with inflammatory bowel disease.

INTRODUCTION: Diagnosis of inflammatory bowel disease (IBD) and differentiation between Crohn's disease (CD) and ulcerative colitis (UC) can be difficult in children. Several previous studies suggest that esophagogastroduodenoscopy (EGD) and biopsies are important in the initial investigation of children with suspected IBD. The aim of the present paper was to assess the importance of EGD in the initial diagnostic appraisal of children with suspected IBD. METHODS: Children diagnosed with IBD over a 4-year period were identified from a dedicated IBD database. Retrospective chart review documented presenting signs and symptoms, endoscopic features in the upper and lower gastrointestinal tract and histological findings on mucosal biopsies. RESULTS: Eighty-six children were diagnosed with IBD of whom 61 (70.9%) had CD, 13 (21.3%) UC, and the remainder, indeterminate colitis. Esophagogastroduodenoscopy was performed in 76 (88.4%). Nine children were diagnosed with IBD solely on the basis of information obtained following EGD. None of these children had colitis and all had abnormal histological findings on review of mucosal biopsies from the upper gastrointestinal tract. Thirteen (23.6%) of 55 children with CD had granulomas noted within biopsies obtained during EGD and another 20 had significant inflammatory changes on histological examination of upper gastrointestinal tract biopsies. Crohn's disease was diagnosed in 25 of 38 children with pan-colitis. Thirteen children were correctly classified as having CD only following assessment of their upper gastrointestinal tract. This included the presence of upper gut granulomata in eight children. CONCLUSION: The performance of EGD in these children with IBD provided additional diagnostic yield and guided the differentiation of disease type in many patients. Esophagogastroduodenoscopy is an essential component in the initial diagnostic assessment of children with possible CD or UC.

Food allergy, coeliac disease and chronic inflammatory bowel disease in man.

It is often stated that the gastrointestinal tract has a limited number of responses to pathogens. Entirely different agents can produce a similar histopathological reaction. However, the expression of the disease in man is very heterogeneous, it varies with the age of the subject and is to a certain extent genetically determined. For example, food allergy is frequent in childhood and not common in adulthood. The intestinal mucosa in the child with cows milk allergy shows a 'flat' mucosa, which may be indistinguishable of that observed in gluten sensitive enteropathy or coeliac disease. Subjects with other forms of food allergy may have a morphologically normal small intestinal mucosa, occasionally with increased IgE plasma cells and often only characterised by an increased intestinal permeability. An abnormal intestinal permeability is one of the hallmarks of an inflamed gut, however, subjects with a latent form of coeliac disease have an abnormal permeability only without overt signs of inflammation. Recently, it has become clear that what determines the characteristics of the intestinal inflammatory response is dependent on the cytokines involved during the response and this seems to be the same in the stomach, the small intestine and the colon. A so-called Th1 response, with an increased production of IFN-gamma, TNF-alpha and other pro-inflammatory cytokines, occurs in the stomach when infected by Helicobacter pylori, in the small intestine when the subject with coeliac disease consumes normal bread and during the active phases of Crohn's disease. A Th2 response is characteristic of the allergic subject and there is some evidence that it is the predominant response in subjects with ulcerative colitis. We still do not know the fine-tuning of the cytokine response but IL-12 appears to be a key cytokine in polarising the response to a Th1 type. More recently it has become clear that the intestinal mucosa has a unique subset of CD4+ T cells that secrete TGF-beta (Th3 cells) that provide help for IgA. These cells have downregulatory properties for Th1 cells and therefore play an important role in the active suppression of oral tolerance and IgE response. What determines that an individual develops one of these diseases? It is now clear that these different pathological entities are multifactorial. Different environmental factors and a complex genetic predisposition where more that one gene and more than one chromosome are involved. The extent and severity of the inflammatory response depends on the genetic diversity of the bacteria or the amount of the antigen on the one hand and on the genetic constitution of the host on the other. The abnormal immune response in the human gut is predominantly a Th1-like inflammatory response. This can be elicited by bacteria, peptides, possibly the bacterial flora and some viruses. The recent findings in the pathogenesis of the intestinal inflammatory response will probably alter the therapy of the future.

Thrombosis and inflammatory bowel disease.

Interaction between thrombosis and inflammation is increasingly recognized. With this, interest has arisen in the role of thrombosis in inflammatory conditions, including the inflammatory bowel diseases. Although the association between active inflammatory bowel disease and thromboembolic complications has long been known, there has been a resurgence in research into the role of thrombosis and the hemostatic system in the pathogenesis of both ulcerative colitis and Crohn's disease. Here we review the increased frequency of thromboembolic complications occurring in patients with inflammatory bowel disease; whether thrombosis might play a part in the initiation and maintenance of inflammation in inflammatory bowel disease; abnormalities of the coagulation system found in patients with inflammatory bowel disease; platelet dysfunction in inflammatory bowel disease; the mechanisms by which hemostatic processes might be proinflammatory in inflammatory bowel disease; and how these interactions might impact not only on the prevention of complications, but also on the treatment of the underlying inflammation in inflammatory bowel disease.

Reduced migration of fibroblasts in inflammatory bowel disease: role of inflammatory mediators and focal adhesion kinase.

BACKGROUND & AIMS: Crohn's disease (CD) and ulcerative colitis (UC) are associated with chronic tissue damage and continuous tissue repair. A central, but not well-characterized, event during this process is the migration of activated fibroblasts to the wound. METHODS: Human colonic lamina propria fibroblasts (CLPF) were isolated from patients with CD and UC and from healthy controls and were characterized by immunocytochemistry. Migration assays of CLPF were performed in the modified 48-well Boyden chamber. Focal adhesion kinase (FAK) and FAK autophosphorylation in migrating CLPF were determined by Western blotting. FAK mRNA expression was investigated by Northern blotting. RESULTS: The migration of CD-CLPF and UC-CLPF was significantly reduced when compared with control-CLPF. This was correlated with a decrease in FAK phosphorylation, whereas, in migrating control-CLPF, an increase was found. Similarly, the presence of the inflammatory mediators interferon (IFN)-gamma (50 ng/mL) or tumor necrosis factor (TNF) (30 ng/mL) in conditioned medium significantly reduced the migration of control-CLPF to 41% +/- 4% or 30% +/- 7%, respectively. Preincubation of control-CLPF with TNF (20 ng/mL) and IFN-gamma (10 ng/mL) for 3 days reduced their migratory response to 10% of control (P < 0.001), which also was correlated with a decrease in FAK phosphorylation. Culture of IFN-gamma/TNF-treated CLPF for a further 7 days without cytokines did not restore the migratory potential and FAK phosphorylation, indicating a persistent functional change. CONCLUSIONS: CD- and UC-CLPF have a reduced migratory potential compared with normal CLPF. That may be caused by contact with IFN-gamma and TNF. This loss of migratory potential was correlated with diminished FAK phosphorylation.

ANCA in systemic vasculitides, collagen vascular diseases, rheumatic disorders and inflammatory bowel diseases.

It was the aim of this study to reevaluate the diagnostic significance and clinical implication of ANCA after testing sera from 13,606 patients for the presence of ANCA. Our data confirm the high specificity (97%) and sensitivity (80%) of cANCA for Wegener's granulomatosis. pANCA were found in renal vasculitides (60%), collagen vascular diseases (SLE 20%, Sjögren's syndrome 26%, polymyositis 16%) and rheumatic disorders (Felty's syndrome 50%, rheumatoid arthritis 20%). A third fluorescence pattern in sera of patients with inflammatory bowel disease (ulcerative colitis 28/72, Crohn's disease 6/84), here called xANCA, was seen. Target antigens of granule proteins from PMN and monocytes (proteinase 3, myeloperoxidase, elastase, cathepsin G, lactoferrin, lysozyme) were identified.

Skeletal muscle disorders associated with inflammatory bowel diseases: occurrence of myositis in a patient with ulcerative colitis and Hashimoto's thyroiditis--case report and review of the literature.

Ulcerative colitis (UC) and Crohn's disease are inflammatory bowel diseases often associated with extra-intestinal manifestations. Of these, neutrophilic dermatoses and arthropathies are the more frequently observed, while the occurrence of striated muscle disorders, namely, myositis, has been very rarely diagnosed in these kinds of patients. The coexistence of immuno-mediated diseases in patients with inflammatory bowel diseases and myositis suggests a common aetiopathogenetic mechanism underlying these conditions. The present report refers to a rare case of a 51-year-old female with UC and Hashimoto's thyroiditis who developed myositis.

Health-related quality of life and psychological distress in a population-based sample of Swedish patients with inflammatory bowel disease.

BACKGROUND: The chronicity of inflammatory bowel disease (IBD) and effects of medical and surgical treatments probably affect the daily lives of patients and may thus impair their health-related quality of life and psychological well-being. METHODS: Health-related quality of life and psychological distress were investigated in a population-based Swedish sample of patients with IBD. A total of 492 patients, 331 with ulcerative colitis (UC) and 161 with Crohn disease (CD), filled out the Short Form-36 (SF-36), the Inflammatory Bowel Disease Questionnaire (IBDQ) and the Hospital Anxiety and Depression (HAD) scale. RESULTS: Patients with UC reported higher (superior) levels in all dimensions of health-related and disease-specific quality of life than did patients with CD. CONCLUSIONS: Having an ileostomy does not seem to affect patients' quality of life, while having ileoanal anastomosis appears to reduce patients' quality of life in several of the dimensions assessed. CD patients reported more anxiety and depression than did patients with UC. The higher psychological distress in the CD group could be explained by more severe symptoms of the disease. Having ileoanal anastomosis may lead to more anxiety and depression, while having an ileostomy does not.

Thromboxane synthase immunohistochemistry in inflammatory bowel disease.

BACKGROUND: Thromboxanes are produced in excess in inflammatory bowel disease. Preliminary reports suggest that ridogrel, a thromboxane synthase inhibitor, is anti-inflammatory and may have therapeutic benefits in patients with ulcerative colitis. AIMS: To investigate the immunohistochemical expression of thromboxane synthase in the colorectal mucosa of patients with inflammatory bowel disease. METHODS: Immunostaining of colonic biopsies from patients with inflammatory bowel disease (n = 13) and controls (n = 5) was performed using a monoclonal antibody to human thromboxane synthase. The extent of staining in cells of the lamina propria was compared in patient and control groups, and was assessed in relation to disease activity scored macroscopically and histologically. RESULTS: The percentage of cells in the lamina propria staining for thromboxane synthase was higher in patients with active inflammatory bowel disease than in those with inactive disease or in controls (p = 0.02 and p = 0.002, respectively). There was a direct correlation between disease activity, measured endoscopically and histologically, and the percentage of lamina propria cells staining for thromboxane synthase (R = 0.71, p = 0.001 and R = 0.72, p = 0.001, respectively). CONCLUSIONS: Increased thromboxane synthase expression in lamina propria cells occurs in active inflammatory bowel disease. It is possible that this results in increased thromboxane synthesis, which may in turn contribute to mucosal inflammation and intramucosal thrombogenesis.

Current concepts of rectum and sphincter preservation in inflammatory bowel disease.

The treatment of inflammatory bowel disease has gone through a dramatic evolution in the last 40 years. Although the medical treatment has shown little progress during this time, surgical concepts have continued to change. Resection of the disease with formation of a well-functioning ileostomy stoma was a great milestone. In recent years, the development of an internal reservoir with a continent ileostomy has greatly improved the status of these patients. However, a pelvic reservoir, using the natural anorectal sphincter, may well be the next step in this evolutionary process.

Extraintestinal Complications of Inflammatory Bowel Disease.

Extraintestinal complications of inflammatory bowel disease (IBD) are often secondary to the underlying disease. Therefore, the first priority is to get active IBD into remission with medications, since surgery for IBD is not indicated for the treatment of extraintestinal complications. Symptoms of extraintestinal complications usually can be treated with simple agents; the treatment of patients with refractory symptoms and the use of more complex drug regimens should be done in cooperation with specialists on affected organ systems. Careful consideration of prescribed drugs is necessary because they may negatively influence the course of IBD.

Long-term monitoring of psychosocial stress and symptomatology in inflammatory bowel disease.

Eleven subjects with inflammatory bowel disease (IBD) participated in a longterm self-monitoring investigation of the relationship between psychosocial stress and IBD symptomatology. Two measurement instruments, the IBD Symptom Diary and the Psychosocial Stress Diary, were completed by each subject for 7 consecutive days each month for one year. Pooled time-series analysis of the influence of daily stress on IBD activity revealed a significant effect. A positive concurrent relationship was found between both daily and monthly psychosocial stress and IBD activity. Investigations of temporal relationship among variables revealed a negative effect of previous month stress on IBD. Results suggest a monthly rebound effect whereby IBD symptom severity is negatively responsive to the severity of the previous month stress. The effects of stress upon IBD were not found to be modified by behavioral coping strategies. These results support the prevailing impression that psychosocial stress contributes to the clinical course of IBD, and specifically suggest an influential role of daily and monthly stress. A pattern matching IBD's characteristic waxing and waning clinical course emerges when the association between stress and IBD is examined from a monthly viewpoint. Refinement of our knowledge of the IBD-stress model calls for replication and explanation of the monthly rebound effect as well as investigations into type of stressor and coping strategy that may influence IBD activity.

Hemostatic abnormalities in inflammatory bowel disease.

Patients affected by inflammatory bowel disease (IBD) frequently suffer from thromboembolic events. Aims of this study were to investigate hemostatic system and the presence of antiphospholipid antibodies (aPL) in IBD patients. Forty-one patients affected by Crohn's disease (CD) and 19 by ulcerative colitis (UC) were studied, compared to 40 healthy control subjects. Platelet count (PLT), PT, aPTT, fibrinogen (Fib), prothrombin fragment F1+2, antithrombin (AT), protein C (PC), protein S (PS), factor XIII (FXIII), plasminogen (PLG), plasminogen activator inhibitor (PA1), spontaneous platelet aggregation in platelet-rich plasma (PRP-SPA) and in whole blood (WB-SPA), and antiphospholipid antibodies (aPL) were evaluated. PLT, Fib, F1+2 and WB-SPA were significantly increased in IBD patients (p at least <0.05) both in active and inactive phases; aPL positivity was more frequent (p<0.05) and FXIII was significantly decreased (p<0.05) in comparison to control subjects. The thrombophilic state of IBD patients is not related to the degree of activity of the disease or to previous thrombotic events; aPL express the immunological alterations connected with IBD and are not the main cause of thrombotic events.

The epidemiology and the pathogenesis of inflammatory bowel disease.

The etiology of inflammatory bowel disease (IBD) is still unknown. However, a satisfactory solution cannot be far away. IBD actually encompasses two diseases, i.e. Crohn's disease (CD) and ulcerous colitis (UC). These diseases resemble each other so closely that they cannot be distinguished even pathologically, but differ from each other sufficiently to regard them as independent entities. Epidemiological observations may be helpful in identifying the true causative factors of this evasive disease. Geographically, the prevalence of the disease has a slope from North to South and, to a lesser degree, from West to East. The Western-Eastern discrepancy can be attributed to a difference in Western life styles. The incidence of the disease has been increasing world-wide of late, but its spread has been slowing down in highly affected countries. Racial and ethnic relations in different populations and immigration studies offer interesting data which can reflect genetic, inherited, environmental and behavioural factors. The disease seems to have a characteristic racial-ethnic distribution: the Jewish population is highly susceptible everywhere, but its prevalence in that population nears that of the domestic society in which they live. In Hungary, the Roma (Gypsies) have a considerably lower prevalence than the average population. This can be attributed to a genetic or environmental influence. According to age, the onset of the disease occurs more often in the second or the third decade of life, but there also is another peak in the 60s. Regarding sexual distribution, there is a slight preponderance of colitis ulcerosa in men and of Crohn's disease in women. It may correspond to the stronger auto-immune affection in the process of Crohn's disease. Environmental factors and behavioural influences also are investigated. Diet, the role of the early ages, smoking habits and the influence of hormonal status and drugs are viewed as useful contributing factors in the manifestation of the disease. Genetic studies show that one-fourth of IBD patients have an affected family member. HLAB27 histocombatibility also plays an important, but not determining role in the development of the disease. Genetic factors seem to have a stronger influence in Crohn's disease than ulcerative colitis. The existence of multiple sclerosis-IBD families may reflect the common genetic background or the similar microbial effect as well. A great number of bacterial and viral factors has been suspected of being infectious factors in IBD, mostly in CD. Mycobacteria, Yersinia, Campylobacter, Clostridium, Clamidias, etc. as well as bacteria and some viruses such as herpes and rotavirus and the primary measles virus. None of them has been proven as a real and exclusively pathogenic factor. Immunological background has an important function in the manifestation of the disease. If an individual has a genetic susceptibility to infections, the down regulation of an inflammation in the bowel wall does not occur in a proper way. This initiates the auto-immune process which is a self-increasing cycle. Extra-intestinal manifestations of IBD are of high importance because they can not only follow intestinal symptoms, but precede them by years. Hepatic and biliary disturbances (primary sclerosing cholangitis), are the most serious complications. Mucocutaneous manifestations can be the first appearance of the main disease (in the mouth). Auto-immune consequences (erythema nodosum) or complications caused even by the therapy can occur. Ocular and musculoskeletal manifestations supposedly have the same genetic background and often precede the intestinal symptoms. Considering the epidemiological, genetic and immunological data, we can conclude that ulcerative colitis and Crohn's disease are heterogeneous disorders of mutifactorial etiology in which hereditary (genetic) and environmental (microbial, behaviour) factors interact to produce the disease.

Cholangiographic abnormalities in patients with inflammatory bowel disease.

Twenty patients with inflammatory bowel disease, abnormal liver function tests and abnormal endoscopic retrograde cholangiograms were found to have a spectrum of abnormalities affecting the intra- and extrahepatic biliary trees. The intrahepatic systems were abnormal in all patients and demonstrated ductal stenosis, ectasia, decreased arborization and major duct obstruction. The extrahepatic systems were abnormal in 75 percent of cases with stenosis, diverticula formation and mural irregularity being the most frequent abnormalities. The value of endoscopic retrograde cholangiography in this patient group is to exclude extrahepatic obstruction, establish a nonoperative diagnosis, and assist in determining the method of treatment.

Perceived sexual dysfunction amongst patients with inflammatory bowel disease.

300 patients with inflammatory bowel disease (IBD) were randomly selected from the community-based register held in Leicester. They were invited to participate in a study investigating personal problems of patients with IBD. 188 patients agreed to participate and were subsequently sent a previously validated questionnaire. A similar questionnaire was sent to buddy controls of similar age, sex and background (n = 76) as well as matched controls drawn at random from general practitioner lists (n = 46). Details sought included demographic data, patients' perception of their disease severity, data relating to treatment, family history, fertility, frequency of sexual intercourse and the effect IBD had on personal relationships. 150 questionnaires were returned from patients (response rate 80%) and 122 from controls. The reliability of a randomly selected group of questionnaires was assessed by direct interview 4 months after the main study (n = 20). There were no demographic differences between the patient and control groups (age: t = 0.67, ns; duration of marriage: t = 0.92, and marital status/number with a regular partner: chi 2 = 14, 12 d.f., p = 0.3). Dyspareunia was commoner amongst patients (n = 15, 38%) than controls (n = 7, 18%), although this was not statistically significant (z = 2.6). There was no significant difference in the overall frequency of sexual intercourse amongst patient and control groups (chi 2 = 12.78, 12 d.f.), even when comparing those with infrequent or no sexual intercourse (chi 2 = 6.98, 4 d.f.) The reliability of these results was confirmed after 4 months when there was no difference in responses in the re-interviewed group.(ABSTRACT TRUNCATED AT 250 WORDS)

Alexithymic characteristics in patients with inflammatory bowel disease.

Twenty patients with inflammatory bowel disease and twenty psychoneurotic patients were studied to assess differences in psychopathology, verbal expression and fantasy formation. The method combined clinical observation, self-assessment questionnaires and quantified projective tests. The psychoneurotic patients showed a higher level of psychopathology, were more verbally expressive, more able to verbalize emotion, and better able to modulate their emotions. Differences in fantasy formation were found. The results provide partial support for the concept of alexithymia (pensée opératoire), a cluster of cognitive traits which have been reported in many psychosomatic patients.
