Maternal correlates of health status in adolescents with inflammatory bowel disease.

OBJECTIVE: People with inflammatory bowel disease (IBD) manifest great variability in health status, but little research has examined correlates of this variability, especially among adolescents with IBD. This study examined family dysfunction, maternal physical symptoms and maternal positive affect (PA) as correlates of variability in depression, pain/fatigue, functional disability and bowel movement frequency among adolescents with IBD. We also tested whether these relationships were independent of maternal negative affect (NA). METHODS: Participants were 62 adolescents with IBD (36 with Crohn's disease (CD) and 26 with ulcerative colitis [UC]) and their mothers. Mothers completed measures about the family and themselves, and adolescents provided health status measures. RESULTS: Controlling for the duration since diagnosis, we found that family dysfunction correlated significantly and positively with bowel movement frequency of the adolescent (partial r=.27), and mother's PA correlated inversely with adolescent's depression (partial r=-.30) and functional disability (partial r=-.28). These relationships remained significant after controlling for maternal NA. Maternal symptoms were not related to the adolescent's health status. Analyses indicated that relationships did not differ for the two IBD subtypes. DISCUSSION: Family dysfunction and maternal PA appear to account for some of previously unexplained variance in the health status of adolescents with IBD. Family interventions should be explored to determine whether these familial and maternal factors influence the health of the adolescent, and whether improving family functioning can lead to health improvements in the children.

Health-related concerns of people who receive psychological support for inflammatory bowel disease.

BACKGROUND: People with inflammatory bowel disease (IBD) cope with a number of disease-specific concerns, which may result in referrals for supportive counselling. OBJECTIVE: To determine differences between the health-related concerns of people with IBD who seek counselling or are referred for psychiatric assessment and those who have no recent contact with counselling or psychiatry. METHODS: Forty-five consecutive patients with IBD referred for psychiatric consultation and 31 IBD out-patients who had recent counselling were compared with 190 IBD out-patients at the same hospital with no recent history of counselling. Disease-related concerns, demographic data and perceived symptom severity were assessed with self-report instruments. RESULTS: Counselling patients had greater overall intensity of concern. Counselling patients differed from noncounselling patients on several measures related to illness severity and were more likely to be female. Correcting statistically for illness severity and sex, the counselled patients had significantly higher levels of concern about being a burden, pain and suffering, feeling out of control, financial difficulties, feeling alone, sexual performance, feeling dirty or smelly and being treated as different. CONCLUSIONS: Beyond the intensity of their physical suffering, patients who seek counselling report a pattern of concern in which interpersonal and emotional concerns are prominent compared with those of out-patients who do not seek counselling. Clinicians should be aware of interpersonal concerns, which may increase the need for empathic support. Psychosocial interventions in IBD may be indicated without respect to psychiatric comorbidity.

Hyperhomocysteinemia and prevalence of polymorphisms of homocysteine metabolism-related enzymes in patients with inflammatory bowel disease.

OBJECTIVES: Patients with inflammatory bowel disease (IBD) have an increased risk of thrombotic complications. Moreover, a hypercoagulable state has been hypothesized as a contributing factor in the pathogenesis of IBD. Recently, a growing amount of interest has focused on mild-to-moderate hyperhomocysteinemia as a risk factor for thromboembolic disease. We aimed to evaluate the prevalence of hyperhomocysteinemia in patients with IBD and to investigate the contribution of genetic defects in the enzymes involved in homocysteine (Hcy) metabolism and vitamin status in determining increased levels of plasma total Hcy (tHcy). METHODS: The concentrations of tHcy, folate, and vitamin B12 as well as the prevalence of methylenetetrahydrofolate reductase (MTHFR) 677C to T mutation and the 68-bp insertion at exon 8 of cystathionine beta-synthase (CBS) were measured in patients with IBD and healthy controls. RESULTS: In all, 17 out of 64 IBD patients (26.5%) and four out of 121 (3.3%) controls had hyperhomocysteinemia with a statistically significant difference (p < 0.0001). No significant difference was found between IBD patients and controls with regard to the prevalence of homozygotes for the C677T variant (TT) of MTHFR or the prevalence of heterozygotes for the CBS-gene mutation (IN). Among the IBD patients the only independent factor significantly associated with hyperhomocysteinemia was folate deficiency (p = 0.0002), regardless of the MTHFR or the CBS genotype. CONCLUSIONS: IBD patients have a higher prevalence of hyperhomocysteinemia than do healthy controls. Folate deficiency is the only independent risk factor in developing hyperhomocysteinemia.

Prevalence of dental caries and periodontal disease in patients with inflammatory bowel disease: a case-control study.

AIM: Previous reports suggest a higher incidence of dental caries in patients with inflammatory bowel disease (IBD) and similarities in the immunopathogenesis of IBD and periodontitis. This study assessed the prevalence of periodontal disease and caries in patients with IBD. METHODS: In the present case-control study, 62 patients seeking treatment of IBD and 59 matched healthy controls of a dental practice were clinically examined. Oral soft-tissue alterations, the decayed, missing and filled tooth surface (DMF-S) index, dentine caries, plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD) and clinical attachment loss (CAL) were evaluated in each patient and in the controls. RESULTS: Patients with IBD showed a significantly higher number of oral manifestations compared with controls. The DMF-S index showed no significant differences, but there was a significantly higher number of subjects with dentine caries in patients with IBD. The mean PPD in patients with IBD was 2.08 versus 2.23 mm in controls (p=0.014). Compared with controls, patients with IBD had more sites with CAL of at least 4 mm (81% versus 64% in controls, p=0.07) and 5 mm (63% versus 46%, p=0.07), respectively. CONCLUSIONS: The results of this case-control study demonstrate a higher frequency of dentine caries in patients with IBD but the periodontal findings showed no distinct differences between cases and controls.

A meta-analysis on the influence of inflammatory bowel disease on pregnancy.

BACKGROUND: Inflammatory bowel disease (IBD) has a typical onset during the peak reproductive years. Evidence of the risk of adverse pregnancy outcomes in IBD is important for the management of pregnancy to assist in its management. AIM: To provide a clear assessment of risk of adverse outcomes during pregnancy in women with IBD. DESIGN: The Medline literature was searched to identify studies reporting outcomes of pregnancy in patients with IBD. Random-effect meta-analysis was used to compare outcomes between women with IBD and normal controls. PATIENTS AND SETTING: A total of 3907 patients with IBD (Crohn's disease 1952 (63%), ulcerative colitis 1113 (36%)) and 320 531 controls were reported in 12 studies that satisfied the inclusion criteria. RESULTS: For women with IBD, there was a 1.87-fold increase in incidence of prematurity (<37 weeks gestation; 95% CI 1.52 to 2.31; p<0.001) compared with controls. The incidence of low birth weight (<2500 g) was over twice that of normal controls (95% CI 1.38 to 3.19; p<0.001). Women with IBD were 1.5 times more likely to undergo caesarean section (95% CI 1.26 to 1.79; p<0.001), and the risk of congenital abnormalities was found to be 2.37-fold increased (95% CI 1.47 to 3.82; p<0.001). CONCLUSION: The study has shown a higher incidence of adverse pregnancy outcomes in patients with IBD. Further studies are required to clarify which women are at higher risk, as this was not determined in the present study. This has an effect on the management of patients with IBD during pregnancy, who should be treated as a potentially high-risk group.

Epidemiology of inflammatory bowel disease among U.S. military veterans.

The Department of Veterans Affairs maintains a computerized patient treatment file that contains all records from veterans treated as inpatients in VA hospitals distributed throughout the United States. Using the patient treatment files from 1986 to 1989, the present study takes advantage of this large national data set to examine demographic and geographic associations of inflammatory bowel disease. Inflammatory bowel disease tended to affect predominantly female, white, and younger veterans, these trends being more marked in cases of Crohn's disease than ulcerative colitis. Hospital discharges secondary to both Crohn's disease and ulcerative colitis appeared to be more frequent in veterans from northern than southern parts of the United States, but did not show a seasonal variation different from the general pattern of all other diagnoses. The results in veterans confirm observations made in other studies and suggest that inflammatory bowel disease among different populations is modulated by similar pathophysiologic mechanisms and environmental risk factors.

Inflammatory bowel disease.

The causes of inflammatory bowel disease (IBD) continue to be an enigma. The incidence has stabilized in Western countries. Involvement of the upper gastrointestinal tract has been found in a high percentage of patients, and can be used to guide the work-up in patients with abdominal complaints. Ileoscopy must be added to the routine investigation when a suspicion of IBD exists. A number of new methods have been proposed, in particular Doppler sonography and magnifying chromoscopy, but their clinical contribution remains to be determined. Carcinoma surveillance is still the major diagnostic problem. New methods are available but need to be evaluated, particularly in patients at increased risk, such as those with primary sclerosing cholangitis.

Nutrition in inflammatory bowel disease.

The nutritional impact of inflammatory bowel disease is notable, both in Crohn's disease and ulcerative colitis. The causes of malnutrition include decreased intake, maldigestion, malabsorption, accelerated nutrient losses, increased requirements, and drug-nutrient interactions. Inflammatory bowel disease causes alterations in body composition and, because of these changes, affects energy expenditure. Various approaches have been most effective in correcting malnutrition, supporting growth, and managing short-bowel syndrome, but the success of primary therapy has been limited.

Interleukin-6 trans-signaling in inflammatory bowel disease.

The pathogenesis of inflammatory bowel disease (IBD) is complex, involving a wide range of molecules including cytokines. Recent investigations support the important role of an interleukin-6 (IL-6) signaling pathway in the development of IBD. However, the molecular mechanisms of this pathway in the intestine remain incompletely understood. The circulating and intestinal levels of IL-6 as well as soluble IL-6 receptor (sIL-6R) are increased in patients with IBD. It is remarkable that the mucosal T cells of IBD patients are extremely resistant to apoptosis and that a large fraction of these cells express membrane-bound gp130 but not IL-6R. The accumulated evidence strongly supports the hypothesis that the development and perpetuation of IBD relies on the increased formation of IL-6/sIL-6R complexes interacting with membrane-bound gp130 on T cells via trans-signaling. These studies suggest that IL-6 trans-signaling may play a role in the development of IBD; they therefore imply the possibility of a selective therapeutic strategy to target this signaling.

Preliminary data on the use of apheresis in inflammatory bowel disease.

In patients with inflammatory bowel disease (IBD), centrifugation has been attempted to remove leukocyte components from whole blood; however, the use of selective filters has proved to result in more active modification of cellular immunity in that 4 times as many white blood cells are removed, which may result in a greater therapeutic effect. Selective apheresis for treatment of IBD, in particular ulcerative colitis (UC), has been used in Japan and some European countries for several years; pilot studies with Adacolumn, a selective therapeutic granulocyte/monocyte apheresis device, in patients with IBD have recently been completed in the United States with favorable results. Unlike conventional pharmacological treatments, selective apheresis may be associated with a relatively low rate of adverse events. Multiple studies have suggested that selective apheresis may be of benefit as a steroid-sparing treatment. In an unblinded randomized trial in 69 steroid-dependent patients with active UC randomized to selective apheresis with Adacolumn or an increased dose of prednisolone, 83% of patients receiving Adacolumn achieved remission compared with 65% of those receiving an increased dose of prednisolone. In another uncontrolled study of 60 patients with active UC, treatment with Adacolumn selective apheresis enabled nearly 70% of steroid-dependent patients to discontinue prednisolone. An unblinded randomized controlled trial of a different selective apheresis device (Cellsorba) versus high-dose prednisolone in patients with active UC showed a greater therapeutic effect (74%) than high-dose prednisolone (38%) and lower frequency of adverse effects (24% versus 68%).

Environment as a critical factor for the pathogenesis and outcome of gastrointestinal disease: experimental and human inflammatory bowel disease and helicobacter-induced gastritis.

Environmental factors play an important role in the manifestation, course, and prognosis of diseases of the gastrointestinal tract such as inflammatory bowel disease (IBD) and Helicobacter pylori-induced gastritis. These two disease complexes were chosen for a discussion of the contribution of environmental factors to the disease outcome in humans and animal models. Dissecting complex diseases like IBD and Helicobacter-induced gastritis has shown that the outcome of disease depends on the allelic constellation of a host and the microbial and physical environments. Host alleles predisposing to a disease in one genomic and/or environmental milieu may not be deleterious in other constellations; on the other hand, microbes can have different effects in different hosts and under different environmental conditions. The impact of the complex interaction between host genetics and environmental factors, particularly microflora, also underlines the importance of a defined genetic background and defined environments in animal studies and is indicative of the difficulties in analyzing complex diseases in humans.

Pathology of chronic inflammatory bowel disease in children.

The term chronic inflammatory bowel disease is usually applied to the idiopathic varieties ulcerative colitis and Crohn's disease but actually encompasses a wide range of colonic inflammatory conditions, which in children includes indeterminate colitis, microscopic colitis, allergic colitis and Behçet's enterocolitis. The pathologist's opinion is considered the final arbiter in the diagnosis of inflammatory bowel disease but classification may be hampered by the considerable histological overlap between the various types of colitis. Accurate diagnosis, particularly in biopsy specimens, thus depends on clinical and radiological input as well as on appropriately selected and adequately prepared material. This chapter discusses in detail the morphological appearances of ulcerative colitis and Crohn's disease with particular emphasis on diagnosis by mucosal biopsy and differential diagnosis in the paediatric age group. The recent demonstration of ulceration-associated cell lineage and trefoil peptide expression in inflammatory bowel disease is also discussed.

[Molecular biology background of inflammatory bowel disease].

The exact pathological background of inflammatory bowel disease has not been clarified yet. Many aspects of genetical and environmental factors, as well as certain alterations of the functions of epithelial cells and immunoregulation which may attenuate chronic inflammation in the gastrointestinal tract are known. These three components have many connecting points. Among the inflammatory bowel disease genes we know only the function of the NOD2/CARD gene, and we have some idea about the OCTN and DRG genes. The function of the intestinal epithelial cells is changed in inflammatory bowel disease. The latter two genes may have a role in the increased permeability, so as the tumor necrosis factor alpha, interferon gamma may play affect it. The interleukin-10 helps the mucosal integrity. The interleukin-6 production is elevated in these diseases, and the interleukin-8 level can be elevated in case of mutation of toll like receptor 5. The tumor necrosis factor alpha, interferon gamma and lymphotoxin-3-alpha increased the chemokine secretion and adhesion molecule expression also. The amount of certain cytokines are changed in inflammatory bowel disease. There were no association between the incidence and phenotype of Crohn's disease and cytokine gene polymorphisms, except the interleukin 6 gene. It seems that these alterations are secondary, and don't play a major role in the pathogenesis of inflammatory bowel disease.

Inflammatory bowel disease in the pediatric patient.

Inflammatory bowel disease is now recognized as a common diagnosis in the pediatric age group. Inflammatory bowel disease has been diagnosed as early as the first few months of life. In addition to the usual gastrointestinal symptoms, diarrhea, abdominal pain, and rectal bleeding, children may exhibit prominent extraintestinal manifestations, such as growth failure, weight loss, anemia, and joint symptoms.

Cerebral sinus thrombosis in patients with inflammatory bowel disease: a case report.

Inflammatory bowel disease (IBD) is an idiopathic inflammatory disease of the gastrointestinal tract. The pathophysiology of IBD is probably the result of the complex interaction of genetic susceptibility and environmental influences. There is a well-known risk of thrombosis in patients with IBD. We present the case of a 53-year-old man with ulcerative colitis, who spontaneously developed intracranial sinus thrombosis that was treated with low molecular weight heparin. Literature was searched to assess the frequency and characteristics of cerebral sinus thrombosis in IBD and the role of certain etiopathological factors in such thrombotic patients.

Cytokine-targeted therapeutic approaches for inflammatory bowel disease.

Although the causes of inflammatory bowel disease currently are not fully understood, increasing evidence implicates cytokines as key factors in the development of this disorder. The rationale for cytokine-targeted therapy for inflammatory bowel disease has been refined significantly and clinical studies have been initiated. Efficacy of therapy with antitumor necrosis factor-alpha antibody has already been established and clinical trials of recombinant interleukin-10 and interleukin-11 are in progress. Recent investigations have also focused on intracellular signaling pathways and transcription factors that regulate production and activation of cytokines. Further elucidation of the immune response and the role of cytokines in inflammatory bowel disease may lead to identification of additional possible targets for therapeutic intervention that could improve management of the disease.

Increased leukocyte adhesiveness/aggregation is the single best biochemical indicator of disease activity in adolescent patients with inflammatory bowel disease.

We determined the relative utility of inflammatory markers in evaluating disease activity in adolescent patients with inflammatory bowel disease (IBD). Sixty-one adolescent patients and 50 age and sex matched volunteers who served as controls were evaluated prospectively. The erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), white blood cell count (WBCC), and the leukocyte adhesiveness/aggregation (LAA) test were determined in each patient. There were 28 subjects in remission and 33 in relapse. Their percentage of aggregated white blood cells in the peripheral blood was 7 +/- 5 and 16 +/- 8, respectively, when compared with the control group (5 +/- 3) (p < 0.0001). Moreover, the LAA test was the only one which could effectively classify patients with IBD into their correct diagnostic categories of remission, mild-moderate, or moderate-severe disease activity. The LAA test is superior to other acute phase reactants used in daily practice to detect the presence of inflammation as well as for the assessment of its severity in adolescent patients with IBD. In addition, our findings may have biological relevance to the disease process and its potential manipulation by anti-adhesive agents.
