Abstract Background: It is essential in clinical management to determine the disease activity in ulcerative colitis (UC) patients. At present, the most accurate way of evaluating the UC severity is endoscopy with biopsy. Fecal calprotectin (FCP) is a non-invasive biomarker that is frequently used for monitoring of intestinal inflammation. Aims: The purpose of our study was to assess the role of FCP as a noninvasive indicator for UC disease activity. Materials and methods: This prospective study enrolled 116 patients with UC (56 with quiescent UC and 60 with active UC) and 36 controls, referred for colonoscopy to our Center. Colonoscopy was performed in all the patients and the findings were graded according to Mayo endoscopic score (EMS) and UC endoscopic index of severity (UCEIS). FCP was analyzed in stool samples by means of point-of-care desk-top Quantum Blue® method. Results: There was no significant difference between mean FCP levels in controls and UC patients in remission (р=0.205). Mean FCP in patients with active UC was significantly higher than that in controls (p<0.001) and in patients in remission (p<0.001). FCP significantly correlated with UCEIS (r = 0.869, p<0.001) and EMS (r = 0.814, p<0.001). Conclusion: The strong correlation with endoscopic disease activity suggests that FCP is a useful biomarker for noninvasive diagnosis and monitoring of disease activity in UC patients.

Abstract Background: Fecal calprotectin is largely applied as a non-invasive intestinal inflammation biomarker in human medicine. Previous studies in pigs investigated the levels of fecal calprotectin in healthy animals only. Thus, there is a knowledge gap regarding its application during infectious diarrhea. This study investigated the usefulness of fecal calprotectin as a biomarker of intestinal inflammation in Brachyspira hyodysenteriae and Salmonella Typhimurium infected pigs. Results: Fecal samples from pigs with colitis (n=18) were collected from animals experimentally inoculated with B. hyodysenteriae G44 or from sham-inoculated controls. Fecal samples from pigs with enteritis (n=14) were collected from animals inoculated with Salmonella enterica serovar Typhimurium or from sham-inoculated controls. For both groups, fecal samples were scored as: 0 = normal; 1 = soft, wet cement; 2 = watery feces; 3 = mucoid diarrhea; and 4 = bloody diarrhea. Fecal calprotectin levels were assayed using a sandwich ELISA, a turbidimetric immunoassay and a point-of-care dipstick test. Fecal calprotectin levels were greater in colitis samples scoring 4 versus ≤ 4 using ELISA, and in feces scoring 3 and 4 versus ≤ 1 using immunoturbidimetry (P < 0.05). No differences were found in calprotectin concentration among fecal scores for enteritis samples, regardless of the assay used. All samples were found below detection limits using the dipstick method.Conclusions: Fecal calprotectin is a potential non-invasive biomarker of infectious colitis, but it is not suitable for detection of enteritis. While practical, the use of commercially available human presents sensitivity limitations. Further studies are needed to validate the field application of calprotectin as a marker.

BACKGROUND Introducing a non-invasive method for determining disease activity is important in patients with ulcerative colitis (UC). So in this study, we aimed to assess the association between disease activity index and microalbuminuria in patients with UC. METHODS In the present cross-sectional study, 84 patients with UC were selected. The disease activity was calculated by the partial Mayo clinic score. Microalbuminuria was assessed using the immunoturbidimetric method in a first-voided sample in the morning in two consecutive days and the mean of these two measurements was reported as urinary microalbumin level. Serum C reactive protein (CRP), erythrocyte sedimentation rate (ESR), and fecal calprotectin were measured respectively using conventional turbidimetric immunoassay, Westergren method, and ELISA methods. RESULTS The mean age of the participants was 40.01 ± 12.85 years, 60.8% of them were female and 53.5% had microalbuminuria. The frequency of microalbuminuria was significantly higher in patients with active compared with inactive inflammatory bowel disease (IBD). There were significant differences between the patients with active and inactive disease regarding CRP, ESR, and calprotectin (p < 0.001). Moreover, there was a strong correlation between microalbuminuria and CRP (r = 0.89, p < 0.001), ESR (r = 0.92, p < 0.001), and calprotectin (r = 0.91, p < 0.001). CONCLUSION Microalbuminuria could be used as a non-invasive marker of disease activity in patients with UC.

Abstract Background Fecal calprotectin is largely applied as a non-invasive intestinal inflammation biomarker in human medicine. Previous studies in pigs investigated the levels of fecal calprotectin in healthy animals only. Thus, there is a knowledge gap regarding its application during infectious diarrhea. This study investigated the usefulness of fecal calprotectin as a biomarker of intestinal inflammation in Brachyspira hyodysenteriae and Salmonella Typhimurium infected pigs. Results Fecal samples from pigs with colitis (n = 18) were collected from animals experimentally inoculated with B. hyodysenteriae (n = 8) or from sham-inoculated controls (n = 3). Fecal samples from pigs with enteritis (n = 14) were collected from animals inoculated with Salmonella enterica serovar Typhimurium (n = 8) or from sham-inoculated controls (n = 4). For both groups, fecal samples were scored as: 0 = normal; 1 = soft, wet cement; 2 = watery feces; 3 = mucoid diarrhea; and 4 = bloody diarrhea. Fecal calprotectin levels were assayed using a sandwich ELISA, a turbidimetric immunoassay and a point-of-care dipstick test. Fecal calprotectin levels were greater in colitis samples scoring 4 versus ≤ 4 using ELISA, and in feces scoring 3 and 4 versus ≤ 1 using immunoturbidimetry (P < 0.05). No differences were found in calprotectin concentration among fecal scores for enteritis samples, regardless of the assay used. All samples were found below detection limits using the dipstick method. Conclusions Fecal calprotectin levels are increased following the development of colitis, but do not significantly change due to enteritis. While practical, the use of commercially available human kits present sensitivity limitations. Further studies are needed to validate the field application of calprotectin as a marker of intestinal inflammation.

Abstract Background: Endoscopic assessment of disease activity is a key parameter in the management of ulcerative colitis. Whether sigmoidoscopy alone is sufficient to evaluate the disease activity in ulcerative colitis lacks studies. Methods: We retrospectively analyzed the medical records and endoscopic results of patients with ulcerative colitis followed by colonoscopy in seven tertiary hospitals between January 2012 and December 2018. Endoscopic disease activity was scored using the Mayo Endoscopic Score (MES) and Ulcerative Colitis Endoscopic Index of Severity (UCEIS) for each segment from the colonoscopy images. Concordance was evaluated by comparing the highest MES and UCEIS in the rectosigmoid and proximal regions to confirm the usefulness of sigmoidoscopy. Results: A total of 500 colonoscopic examinations from 333 patients were enrolled. Only in 7.6% [k(kappa): 0.893, r(Spearman): 0.906, p<0.001] and 8.6% [k(kappa): 0.890, r(Spearman): 0.914; p<0.001] of cases, MES and UCEIS scored more severely in the proximal colon. Comparison of active disease (MES ≥2) in the rectosigmoid area and the entire colon showed a high concordance rate [k(kappa): 0.899, r(Spearman): 0.904, p<0.001]. Endoscopic healing (MES=0) also showed a high concordance rate [k(kappa): 0.882, r(Spearman): 0.887, p<0.001]. In 38 cases (7.6%) of patients with a higher MES in the proximal area, it was significantly higher in patients with previous extensive colitisConclusions: Sigmoidoscopy and colonoscopy showed a high concordance rate. Therefore, sigmoidoscopy is considered a sufficient substitute for colonoscopy. However, colonoscopy should be considered in patients with previous extensive colitis

Objective. To evaluate the efficacy and safety of mesalamine in conjunction with probiotics for ulcerative colitis. Methods. Random controlled trials (RCTs) were searched in PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure, Wanfang, and VIP (VIP Database for Chinese Technical Periodicals) from inception to October 2019. Methodological quality was assessed by the Cochrane Collaboration tool. The quality of evidence was rated by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). Data analysis was carried out in Review Manager 5.3. Results. A total of fifteen studies met the criteria for inclusion. Thirteen studies reported the clinical efficacy, three studies provided data on the clinical symptom scores, two trials reported disease activity index, four studies evaluated endoscopic score, and twelve studies reported adverse events. For ulcerative colitis (UC), mesalamine and probiotics had better clinical efficacy than mesalamine alone (≤8 weeks: RR = 1.12, 95% CI: 1.07–1.18, P<0.0001; >8 weeks: RR = 1.25, 95% CI: 1.11–1.41, P=0.0003). On the clinical symptom scores, disease activity index, and endoscopic score, UC patients receiving mesalamine and probiotics had significant difference than patients receiving mesalazine alone (MD = −2.02, 95% CI: −3.28 to −0.76, P=0.002; MD = −1.20, 95% CI: −1.76 to −0.65, P<0.001; and MD = −0.42, 95% CI: −0.61 to −0.23, P<0.0001, respectively). There was no statistically significant difference in adverse events between the two groups (RR = 0.88, 95% CI: 0.54 to 1.43, P=0.60). Conclusion. Our meta-analysis results supported that mesalamine and probiotics were effective and safe in treating ulcerative colitis.

Background/Aim. Many arguments prove the pathophysiologic role of histamine in the process of remodeling and joint destruction in rheumatoid arthritis. The aim of our study was to find out if there was a relation between histamine concentration in synovial fluid and blood with clinical expression of disease activity. Methods. Histamine concentration in synovial fluid and blood was determinated in 19 patients with rheumatoid arthritis. Histamine concentration measurement was based on the Shore's fluorometric method. Histamine index (HI) was evaluated as a ratio between histamine concentration in synovial fluid and blood. Disease activity score, DAS 28 (3), with three variables (erythrocyte sedimentation rate, the number of swelled joints and the number of tender joints) was also evaluated. Results. Our results showed that there was no significant difference in concentration of histamine in synovial fluid and blood related to disease activity. However, there was a significant difference in the histamine index which was increased proportionally with disease activity. Conclusion. Our study indicates that histamine index could be useful in estimation of rheumatoid arthritis activity.

Background: Designation of disease activity is serious for the management of systemic lupus erythematosus (SLE). Serum level of β2 microglobulin (β2M) may be associated with illness activity in SLE disease. Since the role of β2M for assessing of illness activity in SLE is not completely clear, the current study aimed to discern evaluation of β2M in patients with SLE and its correlation with sickness activity. Materials and Methods: In this case-control study, 50 patients with SLE disease and 25 healthy individuals were selected in Imam Khomeini Hospital in central of Urmia. Blood samples were collected safely from patients, serum was removed, and β2M measured using an ELISA method. The results for other parameters including C reactive protein, C3, C4, anti dsDNA and erythrocyte sedimentation rate were obtained from patients’ medical record. Data analyzed using appropriate statistical tests including Mann-Whitney U test, Independent f-test, Kruskal-Wallis, and Spearman used for analysis of data. Results: In the current study, a significant difference was seen between two groups in terms of β2M (p < 0.001). Remarkable correlation was seen between the level of β2M with disease activity (p < 0.001). Furthermore, there are significant relevancy between the level of β2M with 24-hour urine protein, ESR, disease activity score, and CRP (p < 0.05). Conclusion: The results revealed that serum amount of β2M in SLE patients is higher compared to healthy ones, which is significantly correlated to score of illness activity, CRP, and ESR in patients with SLE disease. Hence β2M might be an excellent serological marker helping the prediction of sickness activity and inflammation in SLE patients.

Background: Nutritional support is very important in the treatment of Paediatric Inflammatory Bowel Disease (IBD). The role of the Mediterranean Diet (MD) has been understudied in children with IBD. The aims of this study were to assess the dietary intakes of IBD children in comparison with healthy controls (HCs), their adherence to MD; and the relationship between inflammation and dietary behaviors. Methods: Paediatric IBD patients in clinical remission and HCs were enrolled. The nutritional status and adherence to the Mediterranean Diet was evaluated through a 3-day food diary and the Mediterranean Diet Quality Index for Children and Adolescents (KIDMED). Results: The analysis of food diaries showed a significantly higher kilocalorie intake in IBD patients compared to HCs (p = 0.012), an increase in carbohydrates (p = 0.015) and in protein intake (p = 0.024). Both IBD and HCs have an intermediate adherence to MD. The comparison between Crohn’s disease (CD) and Ulcerative colitis (UC) patients showed significant difference in protein intake in CD patients (p = 0.047), as well as for vitamin D (p = 0.044) and iron intake (p = 0.023). Interestingly; in IBD patients we found a significant association between adherence to MD and a low level of fecal calprotectin (p = 0.027). Conclusion: Children with IBD in remission have a sub-optimal food intake compared to HCs. MD seems to correlate to decreased intestinal inflammation.
