Inflammatory Bowel

Tenascin-C (TNC) is an extracellular matrix glycoprotein expressed in response to inflammation and tissue damage. The role of TNC in patients with inflammatory bowel disease (IBD) is not well understood. In this study, we analyzed the expression of TNC in the inflamed mucosa of patients with ulcerative colitis (UC) and Crohn’s disease (CD). Serum TNC levels were determined by the enzyme-linked immunosorbent assay (ELISA), and the levels of TNC in patients with different disease activities were compared. The expression of TNC was derived from a GEO dataset. THP-1 cells were stimulated with TNC to evaluate the proinflammatory role of TNC. We found higher TNC expression in the inflamed mucosa of patients with UC and CD compared with normal controls (NCs). TNC was mainly expressed in the stromal area of the intestinal mucosa. The median serum levels of TNC were significantly higher in UC (median 74.1 ng/ml, range 42.6–102.1 ng/ml) and CD (median 59.2 ng/ml, range 44.0–80.9 ng/ml). We also found that serum TNC levels were correlated with Mayo scores in UC and Crohn’s disease activity index (CDAI) in CD. Through GSE14580, we demonstrated that patients who were nonresponsive to infliximab treatment had higher mucosal TNC mRNA expression. High TNC mRNA expression in the inflamed intestinal mucosa was associated with poor response to infliximab therapy in patients with UC. Furthermore, THP-1 cells stimulated with TNC showed increased expression of IL-6, but not TNF-α, IL-8, MCP-1, or IL-1β. Thus, increased TNC levels may participate in the pathogenesis of IBD and may serve as a biomarker for disease activity and response to treatment with infliximab.

<b><i>Background:</i></b> Intestinal ultrasound is emerging as a non-invasive tool for monitoring disease activity in inflammatory bowel disease patients due to its low cost, excellent safety profile, and availability. Herein, we comprehensively review the role of intestinal ultrasound in the management of these patients. <b><i>Summary:</i></b> Intestinal ultrasound has a good accuracy in the diagnosis of Crohn’s disease, as well as in the assessment of disease activity, extent, and evaluating disease-related complications, namely strictures, fistulae, and abscesses. Even though not fully validated, several scores have been developed to assess disease activity using ultrasound. Importantly, intestinal ultrasound can also be used to assess response to treatment. Changes in ultrasonographic parameters are observed as early as 4 weeks after treatment initiation and persist during short- and long-term follow-up. Additionally, Crohn’s disease patients with no ultrasound improvement seem to be at a higher risk of therapy intensification, need for steroids, hospitalisation, or even surgery. Similarly to Crohn’s disease, intestinal ultrasound has a good performance in the diagnosis, activity, and disease extent assessment in ulcerative colitis patients. In fact, in patients with severe acute colitis, higher bowel wall thickness at admission is associated with the need for salvage therapy and the absence of a significant decrease in this parameter may predict the need for colectomy. Short-term data also evidence the role of intestinal ultrasound in evaluating therapy response, with ultrasound changes observed after 2 weeks of treatment and significant improvement after 12 weeks of follow-up in ulcerative colitis. <b><i>Key Messages:</i></b> Intestinal ultrasound is a valuable tool to assess disease activity and complications, and to monitor response to therapy. Even though longer prospective data are warranted, intestinal ultrasound may lead to a change in the paradigm of inflammatory bowel disease management as it can be used in a point-of-care setting, enabling earlier intervention if needed.

Leukocyte Imaging

A prospective study was initiated to compare the clinically proven results concerning localization/extent and activity of inflammatory bowel diseases with those of 111ln-oxine leukocyte imaging. All patients studied were completely examined with barium enema x-ray, clinical and laboratory investigations, and endoscopy with histopathology. A total of 31 leukocyte scans were performed in 15 patients (12 with Crohn’s disease, 3 with ulcerative colitis). The scans were graded by comparing the cell uptake of a lesion (when present) and a bone marrow area providing a count ratio (CR). The inflammatory lesions were correctly localized on 26 leukocyte scans, and in 21 scans the scintigraphically estimated extent of disease was identical to endoscopy. In 5 cases the disease extent was underestimated, 4 scans in patients with relapse of Crohn’s disease were falsely negative, and in one patient with remission truly negative. The scintigraphically assessed disease activity was also in a good agreement with clinical disease activity based on histopathology in all cases. We conclude that leukocyte imaging provides valuable information about localization and activity of inflammatory bowel disease.

Abstract Background This multicenter prospective study (UMIN000019958) aimed to evaluate the usefulness of serum leucin-rich alpha-2 glycoprotein (LRG) levels in monitoring disease activity in inflammatory bowel disease (IBD). Methods Patients with moderate-to-severe IBD initiated on adalimumab therapy were enrolled herein. Serum LRG, C-reactive protein (CRP), and fecal calprotectin (fCal) levels were measured at week 0, 12, 24, and 52. Colonoscopy was performed at week 0, 12, and 52 for ulcerative colitis (UC), and at week 0, 24, and 52 for Crohn’s disease (CD). Endoscopic activity was assessed using the Simple Endoscopic Score for Crohn’s Disease (SES-CD) for CD and the Mayo endoscopic subscore (MES) for UC. Results A total of 81 patients was enrolled. Serum LRG levels decreased along with improvements in clinical and endoscopic outcomes upon adalimumab treatment (27.4 ± 12.6 μg/ml at week 0, 15.5 ± 7.7 μg/ml at week 12, 15.7 ± 9.6 μg/ml at week 24, and 14.5 ± 6.8 μg/ml at week 52), being correlated with endoscopic activity at each time point (SES-CD: r = 0.391 at week 0, r = 0.563 at week 24, r = 0.697 at week 52; MES: r = 0.534 at week 0, r = 0.429 at week 12, r = 0.335 at week 52). Endoscopic activity better correlated with LRG compared to CRP and fCal on pooled analysis at all time points (SES-CD: LRG: r = 0.636, CRP: r = 0.402, fCal: r = 0.435; MES: LRG: r = 0.568, CRP: 0.389, fCal: r = 0.426). Conclusions Serum LRG is a useful biomarker of endoscopic activity both in CD and UC during the adalimumab treatment.

Abstract Introduction Assessment of disease activity in Crohn’s disease (CD) and ulcerative colitis (UC) is usually based on the physician’s evaluation of clinical symptoms, endoscopic findings, and biomarker analysis. The German Inflammatory Bowel Disease Activity Index for CD (GIBDICD) and UC (GIBDIUC) uses data from patient-reported questionnaires. It is unclear to what extent the GIBDI agrees with the physicians’ documented activity indices. Methods Data from 2 studies were reanalyzed. In both, gastroenterologists had documented disease activity in UC with the partial Mayo Score (pMS) and in CD with the Harvey Bradshaw Index (HBI). Patient-completed GIBDI questionnaires had also been assessed. The analysis sample consisted of 151 UC and 150 CD patients. Kappa coefficients were determined as agreement measurements. Results Rank correlations were 0.56 (pMS, GIBDIUC) and 0.57 (HBI, GIBDICD), with p < 0.001. The absolute agreement for 2 categories of disease activity (remission yes/no) was 74.2 % (UC) and 76.6 % (CD), and for 4 categories (none/mild/moderate/severe) 60.3 % (UC) and 61.9 % (CD). The kappa values ranged between 0.47 for UC (2 categories) and 0.58 for CD (4 categories). Discussion There is satisfactory agreement of GIBDI with the physician-documented disease activity indices. GIBDI can be used in health care research without access to assessments of medical practitioners. In clinical practice, the index offers a supplementary source of information.

Abstract Background Diet may play a role in disease status in patients with inflammatory bowel disease. We tested whether the inflammatory potential of diet, based on a summation of pro- and anti-inflammatory nutrients, is associated with disease activity in patients with Crohn’s disease and ulcerative colitis. Methods Participants completed a disease activity questionnaire (short Crohn’s Disease Activity (sCDAI) or Patient Simple Clinical Colitis Activity Index (P-SCCAI)) and a Food Frequency Questionnaire (FFQ). FFQ data were used to calculate the Dietary Inflammatory Index (DII) which enables categorization of individuals’ diets according to their inflammatory potential on a continuum from pro- to anti-inflammatory. Associations with disease activity were investigated by multiple linear regression. Results The analysis included 329 participants; 168 with Crohn’s disease (median sCDAI score 93 [IQR 47–156]), and 161 with ulcerative colitis (median P-SCCAI score 1 [IQR 1–3]). Mean DII was 0.71 ± 1.33, suggesting a slightly pro-inflammatory diet. In Crohn’s disease, the DII was positively associated with disease activity, even after adjustment for confounders (p = 0.008). The mean DII was significantly different between participants in remission and with mild and moderately active disease (0.64, 0.97 and 1.52 respectively, p = 0.027). In ulcerative colitis, the association was not significant. Conclusions Disease activity was higher in IBD participants with a more pro-inflammatory diet with statistical significance in Crohn’s disease. Although the direction of causality is not clear, this association strengthens the role for diet in medical treatment, which should be tested in an intervention study.

Inflammatory bowel disease (IBD) is often associated with malnutrition. The aim of this study was to compare the body composition of outpatients with IBD during remission and active phase. In order to evaluate disease activity we used Crohn's Disease Activity Index for Crohn's disease (CD) patients and Lichtiger's Index for ulcerative colitis (UC) patients. All patients underwent the analysis of BMI, arm muscle area (AMA) and triceps plus subscapula skinfold thickness (TST+SST) to identify total, muscle and fat mass, respectively. In total 102 patients were evaluated (CD,n50; UC,n52) and the majority was young women. Malnutrition according to BMI was found in 14·0 % of patients with CD and 5·7 % of UC patients. Muscle mass depletion was detected in more than half of the CD and UC patients. The BMI, TST+SST and AMA values were lower in the active phase only in CD patients (P < 0·05). Fat mass depletion was associated with active phase in both CD and UC patients. Body composition parameters obtained using BMI, TST+SST and AMA were not correlated with the presence of fistula in CD patients (P>0·05). In conclusion, patients without signs of malnutrition had fat mass depletion especially in the active phase and muscle mass depletion occurred both in CD and UC patients.

The Impact

Background and Objectives: Anemia is the most frequent complication of inflammatory bowel diseases. Clinically, anemia can affect important quality-of-life (QoL) components, such as exercise capacity, cognitive function, and the ability to carry out social activities. The disease activity has a significant impact on QoL, mainly due to clinical manifestations, which are more severe during the periods of disease activity. Our aim was to estimate the impact of anemia on QoL in patients with Crohn’s disease. Material and Methods. We made a prospective study on 134 patients with Crohn’s disease (CD) in a Romanian tertiary center. The CD diagnosis was established by colonoscopy and histopathological examination. In particular cases, additional examinations were required (small bowel capsule endoscopy, computed tomography enterography, and magnetic resonance enterography). Anemia was defined according to the World Health Organization’s definition, the activity of the disease was assessed by Crohn’s disease activity index (CDAI) score, and the QoL was evaluated by Inflammatory Bowel Disease Questionnaire 32 (IBDQ 32). Results: 44.8% patient had anemia, statistically related to the activity of the disease and corticoids use. We found a strong association between QoL and disease activity on all four sub-scores: patients with more severe activity had a significantly lower IBDQ (260.38 ± 116.96 vs. 163.85 ± 87.20, p = 0.001) and the presence of anemia (127.03 vs. 148.38, p = 0.001). In multiple regression analyses, both disease activity and anemia had an impact on the QoL. Conclusions: Anemia has high prevalence in the CD in northeastern region of Romania. Anemia was more common in female patients, in patients undergoing corticosteroid treatment, and in those with active disease. Both anemia and disease activity had a strong negative and independent impact on QoL.

Abstract Background The prevalence of opportunistic infections in individuals with inflammatory bowel disease (IBD) remains relevant. Viral infections are a common cause of systemic inflammation of the digestive tract. Clinically expressed herpes infections are a serious problem, especially for individuals with prolonged immunosuppression. The aim of this study was t o assess the frequency of detection of herpes-6 type with polyps in patients with IBD. Methods 189 patients with IBD, 102 with ulcerative colitis and 87 with Crohn’s disease were examined. Of the number of patients: 98women, 91man. The age of the patients is from 16 to 63 years (mean age 41.4 ± 4.8), out of 189 patients intestinal polyps were identified in 61 patients with a colonoscopy. In addition to standard clinical and endoscopic examinations, disease activity was assessed by indicators of highly sensitive C-reactive protein, homocysteine, vitamin D in blood serum, albumin in urine, calprotectin, lactoferrin and pyruvate kinase in faeces. All patients underwent a serological blood test by ELISA for specific antibodies to herpesvirus type 1–6 IgG/IgM antibodies, as well as avidity, determination of DNA to herpes viruses of types 1–6 species by PCR in blood and mucosal biopsy. Results Among patients with IBD (n = 189), active herpes viruses in the blood were found in 65 patients (34.4%); of them, 39 patients (20.6% (n = 189) and 60%(n = 65),respectively) were diagnosed with monoherpesvirus infections, and 26 (13.7%(n = 189) and 40%(n = 65), respectively) of myxedvirus infections. PCR of the biopsy material was positive in isolation for type 6 herpes virus in 22 cases (11.6% (n = 189) and 33.8% (n = 65)) and in 34 cases (17.9% (n = 189) and 52.3% (n = 65)) a myxedvirus lesion was detected in the tissue (HV6 + EPB, HV6 + CMV), these indicators were detected in patients with intestinal polyps. Although clinical and endoscopic and laboratory indicators of disease activity were significantly higher in patients with mixed tissue lesions (p˂0.05), the level of faecal pyruvate kinase was higher in patients with polyps, indicating a negative effect of herpes type 6 on the course of inflammatory bowel diseases. At the same time, no significant differences were found between patients with ulcerative colitis and Crohn’s disease. Conclusion The frequency of occurrence of herpes type 6 on PCR biopsy in patients with polyps with IBD is more than 91.8% (36.5% in isolation and 55.7% of mixed lesions) and is accompanied by higher rates of faecal pyruvate kinase, which is already an indicator of emerging malignancy. The authors propose the determination of polyps in patients with IBD HV6 by PCR biopsy of intestinal tissue.
