A Subgroup of First-Degree Relatives of Crohn's Disease Patients Shows a Profile of Inflammatory Markers in the Blood Which Is More Typical of Crohn's Disease Patients Than of Normal Individuals
Introduction. Family member with IBD is the greatest risk factor for developing the disease. The hematological profile of first-degree relatives (FDRs) of Crohn's disease (CD) patients was studied in order to identify healthy FDRs at risk to develop disease. Materials and methods. Thirty CD patients, 90 FDRs, and 28 non-related individuals (controls) were enrolled. Hematological profile and C-reactive protein were determined. Results. All hematological parameters were significantly different in CD patients compared to controls, with significantly higher levels of CRP, WBC, PMN, MONO, and PLT and lower Hb and lymphocyte count. The hematological profile of FDRs showed values between the controls and CD patients with ten FDRs that their parameters matched those of CD patients and significantly different from other FDRs. This group was defined as high-risk relatives (HRRs). Conclusions. Analysis of the hematological profile and CRP level might be proven as a fast, reliable, and less money-consuming tool to identify FDRs with a probable increased risk to develop the disease
The Immunohistochemistry Profile of Lymphocytic Gastritis in Celiac Disease and Helicobacter Pylori Infection: Interplay between Infection and Inflammation
Lymphocytic gastritis (LG) is associated with helicobacter pylori (Hp) and celiac disease (CD). We aimed to clarify
the relationship between Hp infection and CD by defining a unique histopathology profile of LG in these two diseases.
Forty patients who underwent upper endoscopy were divided into four groups: eight controls, ten active CD patients
without Hp, twelve CD negative with Hp, and ten active CD with Hp infection. Antral samples were assessed by
immunohistochemical staining for CD20, CD3, CD4, CD8, CD57, CNA42, and Ki67 for lymphoid aggregates,
intraepithelial lymphocytes (IELs) number, density of lamina propria (LP) lymphocytes, and inflammatory glandular
involvement. Only IELs positive for CD3 and CD8 were increased significantly in CD patients with or without Hp infection.
Hp did not contribute to the number of CD8 IELs. In complicated cases with Hp and suspicious for CD, the number of
CD8+ IELs hints toward a CD rather than Hp infection
Once-Versus Twice-daily Mesalazine to Induce Remission in Paediatric Ulcerative Colitis : A Randomised Controlled Trial
Background: Trials in adults suggested that, in ulcerative colitis [UC], once-daily [OD] dosing of 5-ASA [5-amino salicylic acid] may be as or more effective than twice-daily [BD] dosing. In this induction of remission, investigator-blinded, randomised controlled-trial, we aimed to compare effectiveness and safety of once-versus twice-daily mesalazine in paediatric UC. Methods: Children, aged 4-18 years with a PUCAI [Paediatric Ulcerative Colitis Activity Index] of 10-55 points at inclusion, were randomised in blocks of six with blinded allocation to OD or BD mesalazine, using a weight-based dosing table. The primary outcome was mean PUCAI score at Week 6. Results: A total of 83/86 randomised children were eligible and analysed: 43 in the OD group and 40 in the BD group (mean age 14 +/- 2.7 years, 43 [52%] males, 51 [62%] extensive colitis). The groups did not differ with regard to disease activity or any other parameter at baseline. There was no difference in median PUCAI score between the OD group and BD group at Week 6: 15 (interquartile range [IQR] 5-40) versus 10 [0-40]; p = 0.48]. Response was seen in 25 [60%] OD versus 25 [63%] BD dosing [p = 0.78]. Proportion of children in remission [PUCAI 0.2]. Conclusions: In this first randomised controlled trial in children, no differences were found between OD and BD dosing for any clinical outcome. Remission was achieved in 35% of children treated with mesalazine for active UC.Peer reviewe
Simultaneous analyses of carbohydrate-mediated serum GLP-1 and GLP-2 and duodenal receptor expression in children with and without celiac disease
Background: Variability in glucagon-like peptide (GLP)-1 and GLP-2 plasma concentrations has been suggested in Celiac disease (CD), with inconclusive results. We assessed the association between serum levels of GLP-1 and GLP-2 and their duodenal receptor expression in children with and without CD. Methods: This was a two-part, cross-sectional and prospective cohort study. Group assignment, performed after duodenal samples for mRNA expression of GLP-1 receptor (GLP1R) and GLP-2 receptor (GLP2R) , were taken during esophagogastroduodenoscopy. The control group consisted of patients with normal endoscopy and negative serology. The CD group consisted of patients with positive serology and endoscopy suggestive of CD. All had an oral glucose-tolerance test (OGTT). CD patients underwent a second OGTT after 6 months of a gluten-free diet (GFD). Results: The CD group included 12 patients; 7 males with mean age 9.2 ± 2.5 years. The control group included 10 patients; 5 males with mean age 12 ± 4 years, ( p = 0.14). No differences were detected in basal or peak levels of GLP-1 or GLP-2 between control, naïve CD (before GFD) and treated CD (after GFD) groups. Expression of GLP1R and GLP2R mRNA was similar. Significant positive correlations between glucose and C-peptide secretion ( r = 0.9, p < 0.01) and GLP-1 and GLP-2 ( r = 0.8, p = 0.01) were detected in the control group. Significant negative correlations were found in the naïve CD group between GLP2R expression and glucose secretion ( r = −0.68, p = 0.015) and GLP1R expression and serum GLP-1 ( r = −0.7, p = 0.016). Conclusions: Although no significant differences were detected in secretion patterns or gut receptor expression of GLP-1 and GLP-2 in healthy versus CD pediatric patients, the detected discrepancy between the ligand levels and their tissue receptors requires additional study
Expression of Duodenal Iron Transporter Proteins in Diabetic Patients with and without Iron Deficiency Anemia
The role of iron transport proteins in the pathogenesis of anemia in patients with diabetes mellitus (T2DM) is still unclear. We investigated the expression of duodenal transporter proteins in diabetic patients with and without iron deficiency anemia (IDA). Methods. Overall, 39 patients were included: 16 with T2DM and IDA (group A), 11 with T2DM without IDA (group B), and 12 controls (group C). Duodenal mucosal expression of divalent metal transporter 1 (DMT1), ferroportin 1 (FPN), hephaestin (HEPH), and transferrin receptor 1 (TfR) was evaluated by Western blotting. Chronic disease activity markers were measured as well. Results. FPN expression was increased in group A compared to group B and controls: 1.17 (0.72–1.46), 0.76 (0.53–1.04), and 0.71 (0.64–0.86), respectively (p=0.011). TfR levels were over expressed in groups A and B compared to controls: 0.39 (0.26–0.61), 0.36 (0.24–0.43), and 0.18 (0.16–0.24), respectively, (p=0.004). The three groups did not differ significantly with regard to cellular HEPH and DMT1 expression. The normal CRP and serum ferritin levels, accompanied with normal FPN among diabetic patients without IDA, do not support the association of IDA with chronic inflammatory state. Conclusion. In patients with T2DM and IDA, duodenal iron transport protein expression might be dependent on body iron stores rather than by chronic inflammation or diabetes per se

Nutrient Induced Type 2 and Chemical Induced Type 1 Experimental Diabetes Differently Modulate Gastric GLP-1 Receptor Expression
T2DM patients demonstrate reduced GLP-1 receptor (GLP-1R) expression in their gastric glands. Whether induced T2DM and T1DM differently affect the gastric GLP-1R expression is not known. This study assessed extrapancreatic GLP-1R system in glandular stomach of rodents with different types of experimental diabetes. T2DM and T1DM were induced in Psammomys obesus (PO) by high-energy (HE) diet and by streptozotocin (STZ) in Sprague Dawly (SD) rats, respectively. GLP-1R expression was determined in glandular stomach by RT PCR and immunohistomorphological analysis. The mRNA expression and cellular association of the GLP-1R in principal glands were similar in control PO and SD rats. However, nutrient and chemical induced diabetes resulted in opposite alterations of glandular GLP-1R expression. Diabetic PO demonstrated increased GLP-1R mRNA expression, intensity of cellular GLP-1R immunostaining, and frequency of GLP-1R positive cells in the neck area of principal glands compared with controls. In contrast, SD diabetic rats demonstrated decreased GLP-1 mRNA, cellular GLP-1R immunoreactivity, and frequency of GLP-1R immunoreactive cells in the neck area compared with controls. In conclusion, nutrient and chemical induced experimental diabetes result in distinct opposite alterations of GLP-1R expression in glandular stomach. These results suggest that induced T1DM and T2DM may differently modulate GLP-1R system in enteropancreatic axis
