Background

This study evaluated the clinicopathological features and survival rates of patients with inflammatory bowel disease who developed colorectal cancer (CRC).

Methods

A retrospective review was performed on a prospectively maintained institutional database (1981–2011) to identify patients with inflammatory bowel disease who developed CRC. Clinicopathological parameters, management and outcomes were analysed.

Results

A total of 2,843 patients with inflammatory bowel disease were identified. One thousand six hundred and forty-two had ulcerative colitis (UC) and 1,201 had Crohn’s disease (CD). Following exclusion criteria, there were 29 patients with biopsy-proven colorectal carcinoma, 22 of whom had UC and 7 had CD. Twenty-six patients had a preoperative diagnosis of malignancy/dysplasia; 16 of these were diagnosed at surveillance endoscopy. Nodal/distant metastasis was identified at presentation in 47 and 71 % of the UC and CD group, respectively. Operative morbidity for UC and CD was 33 and 17 %, respectively. Despite the less favourable operative outcomes following surgery management of UC-related CRC, overall 5-year survival was significantly better in the UC group compared to the CD group (41 vs. 29 %; p = 0.04) reflecting the difference in stage at presentation between the two groups.

Conclusions

Patients who undergo surgery for UC-related CRC have less favourable short-term outcomes but present at a less advanced stage and have a more favourable long-term prognosis than similar patients with CRC and CD.  相似文献

Background

Adipocytokines are associated with energy homeostasis and mediate various immune responses and inflammatory processes. Vaspin is a novel adipocytokine that is thought to exhibit anti-inflammatory effects.

Aim

We aimed to evaluate serum vaspin levels in inflammatory bowel disease (IBD) and determine its possible associations with the course and to clarify its intestinal localization.

Methods

Serum samples were obtained from patients with Crohn’s disease (CD; n = 30) and ulcerative colitis (UC; n = 33) and from healthy volunteers (controls; n = 26). Enzyme-linked immunosorbent assays were performed for all patients. Vaspin immunohistochemical staining was performed for intestines affected with IBD.

Results

Serum vaspin concentrations were significantly higher in patients with UC than in patients with CD and controls (422.9 ± 361.9 vs. 163.4 ± 116.2 vs. 147.5 ± 89.4 pg/mL, respectively; P < 0.01). There was no difference in the serum vaspin concentrations between the patients with CD and controls. There was also no difference in the serum vaspin concentrations between the patients with active IBD and those with inactive IBD. However, the serum vaspin concentrations of most patients with UC increased after remission induction. Vaspin was expressed in the adipocytes of the mesenteric adipose tissues but not in the epithelial or inflammatory cells of large intestines of the patients with IBD.

Conclusions

Serum vaspin concentrations are elevated in patients with UC and increase further after remission induction, suggesting that vaspin may aid the auxiliary diagnosis of UC and may be useful for assessing disease activity in patients.  相似文献

Background

While the incidence of inflammatory bowel disease (IBD) among African-Americans (AAs) is increasing, there is limited understanding of phenotypic differences and outcomes by race.

Aim

To describe disease characteristics of AA patients compared to Caucasian (Ca) patients in a tertiary care population.

Methods

We performed a cross-sectional review of the IBD registry at the University of Chicago from January 2008 to January 2013. Data regarding race, phenotype, disease onset, disease duration, medical therapy, and surgical treatment were abstracted from the database, then compared via Pearson’s chi-square analysis, Kruskal–Wallis analysis, and logistic regression with a significance level of p < 0.05.

Results

A total of 1,235 patients with Crohn’s disease (CD) and 541 patients with ulcerative colitis (UC) included 108 AA CD patients and 28 AA UC patients. AA CD patients had an increased rate of IBD-related arthralgias (36.5 vs. 23.9 %, p < 0.01) and surgery (p < 0.01), less ileal involvement (57.8 vs. 71.0 %, p < 0.01), and no differences for other extraintestinal manifestations or disease locations compared to Ca CD patients. AA UC patients were older at diagnosis, had an increased rate of arthralgias (28.6 vs. 14.6 %, p = 0.047) and ankylosing spondylitis/sacroiliitis (7.1 vs. 1.6 %, p = 0.035), with no differences for disease extent or rate of IBD-related surgeries compared to Ca UC patients. There were no differences in medication usage by race for CD and UC patients.

Conclusion

We identified significant differences in disease characteristics and extraintestinal manifestations between AA and Ca IBD patients in a large tertiary care population. These results have implications for future genotype-phenotype studies.  相似文献

Purpose

Variants modulating expression of the prostaglandin receptor 4 (PTGER4) have been reported to be associated with Cohn’s disease (CD), but the clinical impact remains to be elucidated. We analyzed these variants in a large German inflammatory bowel disease (IBD) cohort and searched for a potential phenotype association.

Methods

The variants rs4495224 and rs7720838 were studied in adult German IBD patients (CD, n?=?475; ulcerative colitis (UC), n?=?293) and healthy controls (HC, n?=?467). Data were correlated to results from NOD2 genotyping and to clinical characteristics.

Results

We found a significant association for the rs7720838 variant with overrepresentation of the T allele to CD (p?=?0.0058; OR 0.7703, 95 % CI 0.641–0.926) but not to UC. Furthermore, logistic regression analysis revealed that the presence of the T allele was associated with stricturing disease behavior in CD patients (p?=?0.03; OR 1.84, 95 % CI 1.07–3.16). Interestingly, the chance for developing stricturing disease behavior was enhanced if mutant alleles in both rs7720838 and NOD2 were present (OR 2.87, 95 % CI 1.42–5.81; p?=?0.003). No overall association to CD or UC was found for the rs4495224 variant.

Conclusions

The PTGER4 modulating variant rs7720838 increases susceptibility for CD and might resemble a risk factor for stricturing disease behavior.  相似文献

Background

Little is known about the role of follow-up endoscopy in patients with inflammatory bowel disease (IBD).

Aim

The present study aimed to evaluate whether repeated endoscopies would be beneficial in improving outcomes of patients with IBD.

Methods

Patients who had been initially confirmed to have IBD at two tertiary hospitals in Korea were regularly followed and included in this study. The clinical impact as assessed by the presence or absence of a change in management after endoscopy and cumulative hospitalization rate was compared between two groups classified according to the presence or absence of indications.

Results

A total of 188 patients with IBD were enrolled [69 patients with Crohn’s disease (CD) and 119 with ulcerative colitis (UC)]. Of these patients, 130 underwent follow-up endoscopy (48 with CD and 82 with UC). The rate of management change was significantly higher in the group with indications for follow-up endoscopy (p = 0.001 in CD and <0.001 in UC). The presence of any indications for follow-up endoscopy was found to be a significant predictor of hospitalization risk in patients with UC (p = 0.015), but not in those with CD. However, there was no significant difference in cumulative hospitalization hazard with respect to treatment change in patients without any endoscopic indications (p = 0.561 in CD and 0.423 in UC).

Conclusions

Follow-up endoscopy might not have a significant impact on the overall clinical course and outcomes in patients with IBD. However, the presence of endoscopic indications predicts a poor clinical outcome in UC.  相似文献

Background

As several factors can contribute to low bone mineral density (BMD), we investigated the role of vitamin D in low BMD while controlling for other risk factors in inflammatory bowel diseases (IBD) patients.

Methods

We conducted a prospective cross-sectional study between 2008 and 2012 in adult IBD patients. Demographic data including age, gender, ethnicity, BMI, along with disease type and location, vitamin D levels, prior corticosteroid use, and anti-TNF use were recorded and evaluated with DEXA results.

Results

A total of 166 patients [105 Crohn’s disease (CD), 61 ulcerative colitis (UC)] qualified for the study. Low BMD was found in 40 %, twice as frequently in CD than in UC (p = 0.048). Higher prevalence of low BMD was associated with those of male gender (p = 0.05), Asian ethnicity (p = 0.02), and history of corticosteroid use (p = 0.001). Age, body mass index, or disease location did not increase the risk of low BMD. The overall prevalence of low vitamin D was 60 %, with insufficiency (25-hydroxy levels between 20 and 30 ng/mL) found in 37 % and deficiency (levels <20 ng/mL) found in 23 % of the patients. Vitamin D insufficient and deficient patients were two times (p = 0.049) and almost 3 times (p = 0.02) as likely to have low BMD, respectively.

Conclusions

Low vitamin D, male gender, Asian ethnicity, CD, and corticosteroid use significantly increased the risk of having low BMD, while age and disease location did not affect BMD in our IBD population. It remains important to evaluate for vitamin D nutritional deficiency and limit corticosteroid use to help prevent low BMD in IBD patients.  相似文献

Introduction

We aimed to determine the prevalence and duration of prodromal periods in patients with celiac disease and inflammatory bowel disease (Crohn??s disease and ulcerative colitis). Furthermore, we explored to what extent vague abdominal symptoms consistent with both disorders were attributed to irritable bowel syndrome (IBS) and if the presence of prodromal IBS (P-IBS) had an impact on prodrome duration.

Methods

In the study, 683 biopsy-proven patients (celiac n = 225, ulcerative colitis n = 228, Crohn??s disease n = 230) completed a postal survey including an assessment of prodromal periods and IBS symptoms during both the prodrome and at present (achieved by completion of the ROME II criteria). Results were compared to age/sex-matched controls (n = 348).

Results

Crohn??s disease patients had the highest prevalence of prodromes (94%) in comparison to ulcerative colitis (48%) and celiac disease (44%). However, Crohn??s disease patients have the lowest prevalence of P-IBS (29%) in comparison to ulcerative colitis (38%) and celiac disease (67%). Prodrome duration in patients with P-IBS Crohn??s disease was 4 years in comparison to 2 years without (p = 0.018). Prodrome duration in P-IBS celiac disease was 10 years in comparison to 7 years without (p = 0.046). Prodrome duration in patients with ulcerative colitis was not affected by P-IBS (p ?? 0.05). Age and sex were not confounding factors.

Conclusions

This is the first study to make direct comparisons of prodrome periods between celiac disease and IBD. Prodrome duration in celiac disease is significantly longer and more often characterized by P-IBS than IBD. In celiac disease and CD, P-IBS increases prodrome duration. This may represent a failure to understand the overlap between IBS and celiac disease/IBD.  相似文献

Background

Recent years have seen the emergence of Crohn's disease (CD) in India and the predictors of disease behavior and surgery in these patients are not known.

Methods

The demographic and clinical profiles of patients diagnosed to have CD from January 1995 to December 2008 were analyzed retrospectively and associations with disease behavior and surgery were determined using multivariate analysis.

Results

Two hundred and twenty-three patients (age 35?±?14.7 years, males 57.9 %) were included. Extraintestinal manifestations were noted in 27.4 % patients. There was a median delay of 24 months to diagnosis; 66 (29.6 %) patients received antitubercular therapy prior to diagnosis. The most common site of involvement was ileocolonic (40.4 %), and the most common disease behavior was nonstricturing and nonpenetrating (57.8 %). The disease was moderate to severe in 79 %. Around 40 % patients had a relapsing course of illness. Seventy-three patients (32.7 %) had at least one surgical intervention. Independent associations with aggressive disease behavior included the presence of small bowel disease and longer duration of illness. Predictors of surgical intervention were male sex, small bowel disease, perianal disease, and aggressive disease behavior.

Conclusion

Diagnosis of CD is still delayed in India. Longer duration of illness predicted aggressive disease behavior. Surgery was performed more often in males with aggressive disease involving the small bowel and perianal area.  相似文献

Background

Approximately 5–10 % of ulcerative colitis (UC) patients who undergo ileal pouch-anal anastomosis (IPAA) will develop postoperative complications such as refractory pouchitis or a change in diagnosis to Crohn’s disease (CD). Serological markers and histologic aspects of the pouch such as pyloric gland metaplasia (PGM) have been associated with a risk for these complications.

Methods

Twenty-eight IPAA patients with either CD of the pouch or chronic pouchitis (cases) and 36 IPAA controls who experienced a normal postoperative course were originally consented. Of these 64 subjects, 22 cases and 17 controls had histopathologic and serologic data available and were subsequently enrolled. Demographic and clinical data were entered into a database, blood analyzed for serological markers (Prometheus Labs, San Diego, CA) and biopsies of the pouch and the afferent limb reviewed by two GI pathologists.

Results

Of the cases, 55 % (12/22) had evidence of PGM in their pouch and/or small bowel biopsies, as compared to 12 % (2/17) of the controls (p = 0.006). Of 13 subjects with CD, 77 % (10/13) were found to have PGM versus subjects with chronic pouchitis in which 22 % (2/9) were found to have PGM (p = 0.03). There was a trend of ASCA positivity (both IgG and IgA, p = 0.20) and of higher ASCA titer levels (p = 0.07) with postoperative complications.

Conclusion

This study suggests that the presence of ileal pouch PGM is associated with postoperative complications and favors a diagnosis of CD over UC with chronic pouchitis.  相似文献

Background

Inflammatory bowel disease (IBD) associated with primary sclerosing cholangitis (PSC) is reported to be mild and prone to right-side predominance with rectal sparing. However, no dedicated studies evaluating patterns of presentation of liver disease with respect to IBD are available.

Methods

We performed a detailed histological examination of the colonic biopsies in the context of PSC, identifying 97 patients [89 with ulcerative colitis and ten with Crohn’s disease (CD)] stratified into two groups, based on their initial disease presentation: hepatic/biliary (group 1—PSC-IBD; n = 56) versus colonic (group 2—IBD-PSC; n = 41).

Results

Inflammatory bowel disease that preceded PSC had a tendency to have a “pan-colitis” distribution; this group included all patients with CD. Inflammatory bowel disease diagnosis that followed PSC presentation was more likely to be right-sided, sparing the descending, sigmoid and rectal regions (p = 0.002). In both groups, colitis was mild with focal deep plasmacytosis and occasional mild cryptitis. Active cryptitis with crypt abscesses, surface erosion and ulceration were not identified in any of the patients.

Conclusion

Colitis associated with PSC shows mild disease activity and the colitis pattern is associated with disease presentation, i.e. colitis preceding PSC (IBD-PSC cohort) typically have a pancolitic distribution, while colitis following PSC (PSC-IBD cohort) demonstrates right-sided predominance. Awareness by pathologists and clinicians of these patterns of inflammatory bowel disease is important and of use in directing appropriate investigations for patients.  相似文献

Background

Current instruments used to measure disease activity and health-related quality of life in patients with Crohn’s disease (CD) and ulcerative colitis (UC) are often cumbersome, time-consuming, and expensive; although used in clinical trials, they are not convenient for clinical practice. A numeric rating scale (NRS) is a quick, inexpensive, and convenient patient-reported outcome that can capture the patient’s overall perception of health.

Aims

The aim of this study was to assess the validity, reliability, and responsiveness of an NRS and evaluate its use in clinical practice in patients with CD and UC.

Methods

We prospectively evaluated patient-reported NRS scores and measured correlations between NRS and a range of severity measures, including physician-reported NRS, Crohn’s disease activity index (CDAI), Harvey-Bradshaw index (HBI), inflammatory bowel disease questionnaire (IBDQ), and C-reactive protein (CRP) in patients with CD. Subsequently, we evaluated the correlation between the NRS and standard measures of health status (HBI or simple colitis clinical activity index [SCCAI]) and laboratory tests (sedimentation rate [ESR], CRP, and fecal calprotectin) in patients with CD and UC.

Results

The patient-reported NRS showed excellent correlation with CDAI (R 2 = 0.59, p < 0.0001), IBDQ (R 2 = 0.66, p < 0.0001), and HBI (R 2 = 0.32, p < 0.0001) in patients with CD. The NRS showed poor, but statistically significant correlation with SCCAI (R 2 = 0.25, p < 0.0001) in patients with UC. The NRS did not correlate with CRP, ESR, or calprotectin. The NRS was reliable and responsive to change.

Conclusions

The NRS is a valid, reliable, and responsive measure that may be useful to evaluate patients with CD and possibly UC.  相似文献

Purpose

In inflammatory bowel diseases (IBD), risk of thrombosis and production of antibodies are increased. In autoimmune and inflammatory disorders, a role of anti-prothrombin (aPT) antibodies in developing thrombosis has been hypothesised. The aim of the study is to evaluate the prevalence of aPT antibodies in IBD patients, with and without thrombosis.

Methods

Thirty-three IBD patients with thrombosis, 33 IBD patients without thrombosis matched for sex, age, diagnosis and disease activity and 66 sex- and age-matched healthy controls were enrolled. Thrombosis was considered recent when blood sample was obtained within 3 months from the event.

Results

Prevalence of aPT antibodies in thrombotic IBD patients (3/33, 9.1 %), non-thrombotic IBD patients (4/33, 12.1 %) and in healthy subjects (3/66, 4.5 %) did not result significantly different (p?=?0.377). The prevalence of aPT antibodies was more frequent in ulcerative colitis (6/32, 18.7 %) than in Crohn’s disease (1/34, 2.9 %) and healthy controls (p?=?0.022). Among thrombotic IBD patients, the prevalence of aPT antibodies was higher in those with recent (2/9, 22.2 %) than in those with previous thrombosis (1/24, 4.2 %) (p?=?0.103). All thrombotic IBD patients with aPT antibodies were affected by ulcerative colitis with previous history of deep venous thrombosis.

Conclusions

aPT antibodies do not appear to play a relevant role in thrombosis complicating IBD course. A possible association in ulcerative colitis patients with DVT could not be excluded.  相似文献

Background

Identifying patient-level and disease-specific predictors of healthcare utilization in inflammatory bowel disease (IBD) may allow targeted interventions to reduce costs and improve outcomes.

Aim

To identify demographic and clinical predictors of healthcare utilization among veterans with IBD.

Methods

We conducted a single-center cross-sectional study of veterans with IBD from 1998 to 2010. Demographics and disease characteristics were abstracted by manual chart review. Annual number of IBD-related visits was estimated by dividing total number of IBD-related inpatient and outpatient encounters by duration of IBD care. Associations between predictors of utilization were determined using stepwise multivariable linear regression.

Results

Overall, 676 patients (56% ulcerative colitis (UC), 42% Crohn’s disease (CD), and 2% IBD unclassified (IBDU)) had mean 3.08 IBD-related encounters annually. CD patients had 3.59 encounters compared to 2.73 in UC (p < 0.01). In the multivariable model, Hispanics had less visits compared to Caucasians and African-Americans (2.09 vs. 3.09 vs. 3.42), current smokers had more visits than never smokers (3.54 vs. 2.43, p = 0.05), and first IBD visit at age <40 had more visits than age >65 (3.84 vs. 1.75, p = 0.04). UC pancolitis was associated with more visits than proctitis (3.47 vs. 2.15, p = 0.04). CD penetrating phenotype was associated with more encounters than inflammatory type (4.68 vs. 4.15, p = 0.04).

Conclusions

We found that current tobacco use, age <40 at first IBD visit, UC pancolitis, and CD fistuilizing phenotype in addition to Caucasian and African-American race were independent predictors of increased healthcare utilization. Interventions should be targeted at these groups to decrease healthcare utilization and costs.

Background

Neuromuscular fatigue is a common complaint in Crohn’s disease (CD) patients. A correlation between serum vitamin D concentrations and neuromuscular function has been found in the elderly or non-ambulant populations.

Aims

The aim of this study was to determine whether CD patients exhibit impaired neuromuscular function and if so, is there a link between vitamin D and neuromuscular function.

Methods

Crohn’s disease patients (n = 19) with at least one prior small bowel resection and matched controls (n = 19) underwent muscle strength and endurance testing, vitamin D, and nerve function analysis.

Results

Knee extension and flexion peak torque (Nm/kg) were greater in the control group than in the CD patients (P = 0.04 and 0.014, respectively. A significant difference was found between fatigue rates of the rectus femoris (P = 0.015) between CD patients and controls, but no difference was found in serum vitamin D levels between groups (P = 0.317). Knee extension and flexion torque measurements, with age as a covariate, were compared with high and low vitamin D levels. Those subjects with high serum vitamin D levels had a significantly greater extension peak torque (P = 0.045) and extension average torque (Nm/kg) (P = 0.014) than those with low levels.

Conclusion

Crohn’s disease patients with sufficient vitamin D levels experienced a 43 % greater extension peak torque. Although vitamin D deficiency has been associated with neuromuscular dysfunction, there were no differences in serum vitamin D levels between the CD and healthy controls to explain the decreased muscle strength.  相似文献

Background

Introduction of biologic agents in inflammatory bowel disease (IBD) has increased the likelihood of disease remission. Despite resolution of active inflammation, a subset of IBD patients report persistent defecatory symptoms.

Aim

To evaluate a group of patients with inflammatory bowel disease with suspected functional defecatory disorders, by use of anorectal manometric testing and subsequent biofeedback therapy.

Methods

A group of IBD patients with persistent defecatory problems despite clinical improvement were included in this study. These patients had no evidence of left-sided disease. Endoscopic and radiographic study findings and timing in relation to the manometry study were recorded. Anorectal manometry was performed by the standard protocol and included rectal sensory assessment, ability to expel a balloon, and pressure dynamics with simulated defecation.

Results

Thirty IBD patients (Crohn’s 23 patients; ulcerative colitis six patients) presented with defecatory disorders including constipation (67 %) increased stooling (10 %), and rectal urgency and/or incontinence and rectal pain (6 %). All but one patient had anorectal manometric criteria of dyssynergia (presence of anismus motor pattern and inability to expel the balloon). Of the patients who completed biofeedback therapy, 30 % had a clinically significant (≥7-point) improvement in SIBDQ score, with a reduction in health-care utilization after a six-month period (p = 0.02).

Conclusions

Despite remission, some inflammatory bowel disease patients have persistent defecatory symptoms. Defecatory symptoms may not be predictive of an underlying inflammatory disorder. Lack of inflammatory activity and absence of left-sided disease should prompt investigation of functional disorders. Anorectal manometric testing and biofeedback therapy for patients with a diagnosis of dyssynergia may be a useful therapy.  相似文献

Background

Data supporting a role of female hormones and/or their receptors in inflammatory bowel disease (IBD) are increasing, but most of them are derived from animal models. Estrogen receptors alpha (ERα) and beta (ERβ) participate in immune and inflammatory response, among a variety of biological processes. Their effects are antagonistic, and the net action of estrogens may depend on their relative proportions.

Aim

To determine the possible association between the balance of circulating ERβ and ERα (ERβ/ERα) and IBD risk and activity.

Methods

Serum samples from 145 patients with IBD (79 Crohn’s disease [CD] and 66 ulcerative colitis [UC]) and 39 controls were retrospectively studied. Circulating ERα and ERβ were measured by ELISA. Disease activities were assessed by clinical and endoscopic indices specific for CD and UC.

Results

Low values of ERβ/ERα ratio were directly associated with clinical (p = 0.019) and endoscopic (p = 0.002) disease activity. Further analyses by type of IBD confirmed a strong association between low ERβ/ERα ratio and CD clinical (p = 0.011) and endoscopic activity (p = 0.002). The receiver operating curve (ROC) analysis showed that an ERβ/ERα ratio under 0.85 was a good marker of CD endoscopic activity (area under the curve [AUC]: 0.84; p = 0.002; sensitivity: 70%; specificity: 91%). ERβ/ERα ratio was not useful to predict UC activity.

Conclusions

An ERβ/ERα ratio under 0.85 indicated CD endoscopic activity. The determination of serum ERβ/ERα might be a useful noninvasive screening tool for CD endoscopic activity.

Background

Although vitamin D deficiency occurs in inflammatory bowel disease (IBD), it is currently unclear to what extent ethnicity affects vitamin D levels. Our aim was therefore to determine the ethnic variation in serum 25-hydroxyvitamin D status and its association with disease severity in adults with IBD.

Methods

We conducted a prospective cohort study in ambulatory care IBD patients. Clinical disease severity was assessed through validated questionnaires. Serum 25-hydroxyvitamin D levels were used for vitamin D status. C-reactive protein (CRP), ferritin and hemoglobin (Hgb) levels were correlated with serum 25-hydroxyvitamin D levels.

Results

Sixty ulcerative colitis (UC) and forty Crohn’s disease (CD) patients were enrolled comprising 65 % Caucasians and 29 % South Asians. However, South Asians had consistently lower average serum 25-hydroxyvitamin D levels (All 44.8 ± 18.1 nmol/L, UC 48.2 ± 18.3 nmol/L, CD 24.3 ± 13.3 nmol/L). Hypovitaminosis D was found in 39 % of All, 36.7 % of UC and 42.5 % of CD patients. A significantly higher proportion of South Asians were vitamin D deficient when compared to Caucasians in All and CD groups (58.6 % vs. 30.8 %, p = 0.01 and 85.7 % vs. 32.3 %, p < 0.01, respectively).

Conclusions

A significantly higher percentage of South Asians had hypovitaminosis D when compared to Caucasians. Disease severity trended towards an inverse relationship with vitamin D status in all South Asian and Caucasian CD patients, although most patients in this study had only mild to moderate disease. We suggest that vitamin D supplementation should be considered in all adult IBD patients.  相似文献

Background

Little is known concerning the relationship of disease activity and sleep disturbances in inflammatory bowel disease (IBD) and specifically in patients with Crohn’s disease.

Aim

This study examined the prevalence of poor sleep quality in patients with active and inactive Crohn’s disease compared with healthy controls.

Methods

Participants included 108 patients with Crohn’s disease attending the IBD clinic of a tertiary medical center in 2009–2010 and 36 healthy volunteers. All prospectively completed a demographic questionnaire and the Pittsburgh sleep quality index (PSQI). Patients with Crohn’s disease completed the Crohn’s disease activity index (CDAI) and were divided into two groups accordingly: inactive disease (CDAI ≤150) and active disease (CDAI >150). Data on disease duration, medications, complications, and treatment were collected from the medical files.

Results

Seventy-one patients had inactive Crohn’s disease and 37 had active disease. All three groups were similar in mean age, sex distribution, and body mass index. Mean duration of Crohn’s disease was 10.22 ± 8.6 years; 40 patients (37 %) had ileal disease, 16 (15 %) colonic disease, and 56 (50 %) ileo-colonic disease. Patients with active disease had a significantly higher mean ± SD global score on the PSQI (8.6 ± 2.4; indicating poorer sleep quality) than patients with inactive disease (4.6 ± 1.9) or control subjects (5.1 ± 1.7) (p < 0.0001 for both), with no significant difference between the inactive-disease and control groups. The correlation between the CDAI and PSQI scores was statistically significant (p < 0.001).

Conclusions

Impaired sleep quality is associated with active Crohn’s disease, but not inactive disease.  相似文献

Background and Objectives

The sudden change in the dietary habits of the Japanese population towards a European/American-style diet since the 1960s is thought to be responsible for the recent increase in the incidence of inflammatory bowel disease (IBD) in Japan. Dietary fatty acid intake influences the fatty acid profiles of vital cell membranes, which might be a source of inflammatory mediators.

Methods

We investigated the fatty acid composition of the erythrocyte membrane in 90 healthy Japanese and 43 initial-onset IBD patients (ulcerative colitis, UC: 25; Crohn’s disease, CD: 18) who had not undergone any dietary intervention to examine the role fatty acids play in the onset of IBD.

Results

The erythrocyte membrane n-3/n-6 ratio of the initial-onset IBD patients was 0.42 ± 0.13, which was not significantly different from that of the healthy Japanese subjects (0.41 ± 0.13). However, the CD patients displayed a significantly lower mean percentage weight (MPW) of linoleic acid (LA) than the healthy subjects (8.25 ± 1.75 vs. 9.90 ± 1.29; p < 0.001), while their MPW of arachidonic acid (AA) was significantly higher than those of the healthy subjects and UC patients (11.22 ± 2.18 vs. 9.76 ± 1.64, p < 0.01; vs. 9.58 ± 1.97, p < 0.01, respectively). The mean delta 6-desaturation index of the CD patients was significantly higher than that of the healthy subjects (1.61 ± 0.65 vs. 1.11 ± 0.26; p < 0.001).

Conclusions

The CD patients displayed significantly higher and lower MPW of AA and LA, respectively, than the healthy subjects, suggesting that delta 6-desaturase is hyperactivated in CD. The cell membrane fatty acid profile might be a therapeutic target in CD.  相似文献

The existing literature on racial differences in Crohn’s disease (CD) activity and quality of life (QOL) is limited and extrapolated from surrogate measures.

Aim

The aim of our study was to compare objective markers of disease activity and QOL over time by race.

Study

A clinical data repository of inflammatory bowel disease (IBD) patients at University of Maryland, Baltimore IBD Program, was used. CD patients from 2004 to 2009 were included if they had greater than or equal to two clinic visits with disease activity and QOL scores during the study period. Differences in disease activity and QOL were compared by race over time.

Results

A total of 296 patients with CD met inclusion criteria; of these, 19 % (56/296) were African Americans (AA) and 81 % (240/296) were Caucasian. Baseline disease activity and QOL scores did not differ by race (p > 0.05). Caucasians had a steady decline in disease activity and increase in QOL. AA experienced a similar pattern of change in disease activity and QOL scores over time; however, the declines were not statistically significant between groups. At each time point post-baseline, disease activity and QOL scores were similar between races.

Conclusion

We found that Caucasian and AA patients with CD had similar disease activity and QOL scores at initial presentation and over time. Thus, AA do not represent a more severe subgroup of CD patients to treat. These findings have important implications for clinicians that care for patients with CD.  相似文献
