The aim of this study was to determine the expression of Ki-67 and PCNA proliferative antigens and the apoptotic index in dogs with various degrees of severity of inflammatory bowel disease (IBD), and to evaluate the applicability of these markers in diagnosing the disease. The study was performed on 28 dogs of different breeds, both sexes, with body weights of 10 to 20 kg, aged 2 to 10 years. The animals diagnosed with IBD were divided into four groups of 7 dogs each, including three groups characterized by various degrees of severity of IBD and a control group. The expression of Ki-67 and PCNA antigens was determined immunohistochemically, and the apoptotic index was expressed as the number of TUNEL-positive lamina propria cells in the duodenum, jejunum and the colon. Regardless of its form, IBD affected the expression of the analyzed proliferation markers and apoptosis in duodenal, jejunal and colonic mucosa, but most of the analyzed parameters were not correlated with the severity of the disease. The severity of IBD was correlated only with the expression of Ki-67 in duodenal villi. The results of the study point to the limited applicability PCNA and the apoptotic index in differentiating and evaluating the progression of IBD in dogs. The estimation of Ki-67 expression may be useful in the evaluation of the severity of IBD in dogs.

Abstract Objectives Although bowel symptoms are often predominant, inflammatory bowel disease (IBD) patients can have several oral manifestations. The aim of this study was to investigate the prevalence of dental caries and periodontal disease in patients with Crohn’s disease (CD) and ulcerative colitis (UC) compared to an age and gender-matched control group of patients without IBD. Material and methods The DMFT (Decayed, Missing, Filled Teeth) scores and the DPSI (Dutch Periodontal Screening Index) of 229 IBD patients were retrieved from the electronic health record patient database axiUm at the Academic Centre for Dentistry Amsterdam (ACTA) and were compared to the DMFT scores and DPSI from age and gender-matched non-IBD patients from the same database. Results The total DMFT index was significantly higher in the IBD group compared to the control group. When CD and UC were analyzed separately, a statistically significant increased DMFT index was observed in CD patients but not in UC patients. The DPSI did not differ significantly between the IBD and non-IBD groups for each of the sextants. However, in every sextant, IBD patients were more frequently edentulous compared to the control patients. Conclusion CD patients have significantly more dental health problems compared to a control group. Periodontal disease did not differ significantly between IBD and non-IBD groups as determined by the DPSI. Clinical relevance It is important that IBD patients and physicians are instructed about the correlation between their disease and oral health problems. Strict oral hygiene and preventive dental care such as more frequent checkups should be emphasized by dental clinicians.

Összefoglaló. Gyulladásos bélbetegségben (IBD) a fájdalomérzés komplex szomatikus és pszichés jelenség. Ez utóbbi komponens pontosabb megértése segíthet a megfelelő kezelési stratégia megállapításában. A szorongásos hangulati zavarok és egyes maladaptív viselkedési minták (dohányzás és alkoholfogyasztás) előfordulási gyakorisága jól dokumentált IBD-ben, a kannabiszhasználat hatása ugyanakkor kevésbé ismert. A szerzők szisztematikus áttekintést végeztek annak megértéséhez, hogy vajon magasabb-e a marihuánahasználat gyakorisága felnőtt IBD-s betegek között egészséges kontrollpopulációhoz viszonyítva, és ha igen, akkor melyek a szerhasználat legfontosabb jellemzői. A kutatási periódust szándékosan az elmúlt 7 évre korlátoztuk, ugyanis 2013-tól jelentős változások álltak be a kannabinoidok jogi és orvosi megítélésében az USA-ban. Öt elsődleges és több másodlagos adatbázisban kutattunk előre meghatározott kulcsszavak segítségével 2013 óta teljes szöveggel megjelent, angol nyelvű felnőtt IBD-s populációt vizsgáló epidemiológiai tanulmányok vonatkozásában. 143 rekord közül 7 cikk felelt meg a beválogatási kritériumoknak. Eredményeink szerint a kannabiszhasználat gyakorisága IBD-ben szenvedő felnőtt betegek körében valószínűleg magasabb, mint a kontrollpopulációban: a „valaha, bármikor” használók aránya 54–70% között változott (szemben a 46–60% gyakorisággal a kontrollcsoportban), míg az „aktív használók” esetén a gyakoriság 6,8–25% között változott (vs. a kontrollcsoportban tapasztalt 8,6–14%-kal). A prevalenciaadatok széles variabilitása arra utal, hogy a beválogatott epidemiológiai tanulmányok valószínűleg vagy nem voltak megfelelően tervezve, vagy jelentős heterogenitással bírtak. A pszichés tényezők ellentmondásos mintája azt sugallja, hogy a kannabinoidok egyes esetekben ronthatták, más esetben valószínűleg javították bizonyos prominens tünetek megélését. Javasoljuk ezért, hogy a valós prevalencia megállapítása érdekében a keresztmetszeti vizsgálatok mellé ismételt pszichometriai vizsgálatokon alapuló vizsgálatok is bekerüljenek a további kutatásba. Orv Hetil. 2021; 162(12): 443–448. Summary. Pain perception in inflammatory bowel disease (IBD) is beyond a purely somatic process. In-depth understanding of psychologic elements might enable more effective management in this patient group. Anxiety disorders and certain maladaptive coping strategies like smoking and alcohol consumption are well-documented in IBD, unlike the scarcely researched cannabis use. The authors designed a systematic review, to investigate if the prevalence of cannabis use is higher in IBD that in unselected controls. The research window was intentionally set to cover for the past 7 years, as in 2013 major legislative changes took place in the cannabis decriminalisation process in the United States. 5 primary and several secondary databases were researched with a pre-formulated algorithm registered at PROSPERO for full text epidemiological studies published in English language involving adult IBD patients. Out of 143 records, 7 articles met the in/exclusion criteria. Our results suggest that cannabis use among adult patients with IBD is likely to be higher than in the unselected control population. The proportion of “ever” users varied from 54% to 70% (vs. 46–60% in the control group); and for ‘active users’, the prevalence ranged between 6.8% to 25% (vs. 8.6–14% in the control group). The wide variability in prevalence data suggests that the selected epidemiological studies were either inappropriately designed or were too heterogeneous (or both). The contradictory pattern of psychological factors suggests that cannabinoids might improve or worsen IBD depending on case by case basis. We therefore opine that in addition to cross-sectional papers, studies based on repeated psychometric analysis are needed to establish the real prevalence and inform cannabinoid prescription and holistic management in inflammatory bowel disease.

Abstract Purpose Our previous studies demonstrated that mature adipocyte-derived dedifferentiated fat (DFAT) cells possess similar multipotency as mesenchymal stem cells. Here, we examined the immunoregulatory potential of DFAT cells in vitro and the therapeutic effect of DFAT cell transplantation in a mouse inflammatory bowel disease (IBD) model. Methods The effect of DFAT cell co-culture on T cell proliferation and expression of immunosuppression-related genes in DFAT cells were evaluated. To create IBD, CD4+CD45RBhigh T cells were intraperitoneally injected into SCID mice. One week later, DFAT cells (1 × 105, DFAT group) or saline (Control group) were intraperitoneally injected. Subsequently bodyweight was measured every week and IBD clinical and histological scores were evaluated at 5 weeks after T cell administration. Results The T cell proliferation was inhibited by co-cultured DFAT cells in a cell density-dependent manner. Gene expression of TRAIL, IDO1, and NOS2 in DFAT cells was upregulated by TNFα stimulation. DFAT group improved IBD-associated weight loss, IBD clinical and histological scores compared to Control group. Conclusion DFAT cells possess immunoregulatory potential and the cell transplantation promoted recovery from colon damage and improved clinical symptoms in the IBD model. DFAT cells could play an important role in the treatment of IBD.

Concomitant inflammatory bowel disease (IBD) and hepatitis C virus (HCV) infection is a relevant comorbidity since IBD itself exposes to a high risk of liver damage. We aimed to evaluate liver stiffness (LS) in IBD-HCV after antiviral treatment. We enrolled IBD patients with HCV. All patients at baseline underwent LS measurement by elastography. Patients who were eligible for antiviral therapy received direct antiviral agents (DAAs) and sustained viral response was evaluated at the 12th week. A control group was selected within IBD patients without HCV. One year later, all IBD-HCV patients and controls repeated LS measurement. Twenty-four IBD-HCV patients and 24 IBD controls entered the study. Only twelve out of 24 received DAAs and all achieved sustained viral response (SVR). All IBD subjects were in remission at enrollment and maintained remission for one year. After one year, IBD patients who eradicated HCV passed from a liver stiffness of 8.5 ± 6.2 kPa to 7.1 ± 3.9, p = 0.13. IBD patients who did not eradicate HCV worsened liver stiffness: from 7.6 ± 4.4 to 8.6 ± 4.6, p = 0.01. In the IBD control group, stiffness decreased from 7.8 ± 4.4 to 6.0 ± 3.1, p < 0.001. In conclusion, HCV eradication is able to stop the evolution of liver fibrosis in IBD, while failure to treat may lead to its progression. A stable IBD remission may improve LS even in non-infected subjects.

Abstract Background Anthropometric data and dietary intake pattern are poorly known in Asian inflammatory bowel disease (IBD) patients. The aim of this study was to investigate the nutritional status and nutrient intake of IBD patients compared with control population. Methods From February to June 2018, a total of 65 outpatients, including 33 ulcerative colitis (UC) and 32 Crohn’s disease (CD) were prospectively enrolled in Gangnam Severance Hospital. As a control group, age- and gender-matched 260 subjects were included among the Korean National Health and Nutrition Examination Survey (KNHANES) data. Anthropometry and body composition data were collected by bioelectrical impedance analysis(BIA); meanwhile, nutrient intake was measured based on diet diary. Results Based on Asia Pacific criteria, more than half of both UC and control group were obese or overweight, on the other hands, CD was relatively low, about 1/3. Compared with the UC group, body fat index including both fat mass index (FMI) and body fat percentage (BFP) were significantly lower in the CD group. Following nutrients intake including intake of energy, carbohydrate, niacin, sodium and potassium were significantly lower in UC than the control group. Meanwhile, intake of carbohydrate, thiamine, niacin, sodium, potassium and iron was significantly lower in CD than the control group. In addition, the ratio of energy intake through protein and fat was significantly higher in the IBD than the control group. Conclusion Similar to the control group, more than half of UC patients were overweight or obesity, meanwhile, the proportion of obese patients in CD was lower than in the control group. The ratio of energy intake through protein and fat was significantly higher in IBD than in the control group. Our results may have clinical implications for risk of IBD development in terms of dietary pattern and further direction of nutritional intervention.

Increasing rates of inflammatory bowel disease (IBD) are now seen in populations where it was once uncommon. The pattern of IBD in children of Middle Eastern descent in Australia has never been reported. This study aimed to investigate the burden of IBD in children of Middle Eastern descent at the Sydney Children’s Hospital, Randwick (SCHR). The SCHR IBD database was used to identify patients of self-reported Middle Eastern ethnicity diagnosed between 1987 and 2011. Demographic, diagnosis, and management data was collected for all Middle Eastern children and an age and gender matched non-Middle Eastern IBD control group. Twenty-four patients of Middle Eastern descent were identified. Middle Eastern Crohn’s disease patients had higher disease activity at diagnosis, higher use of thiopurines, and less restricted colonic disease than controls. Although there were limitations with this dataset, we estimated a higher prevalence of IBD in Middle Eastern children and they had a different disease phenotype and behavior compared to the control group, with less disease restricted to the colon and likely a more active disease course.

Spermine (SPM) and its precursor putrescine (PUT), regulated by ornithine decarboxylase (ODC) and diamino-oxidase (DAO), are polyamines required for cell growth and proliferation. Only a few studies have investigated the anti-inflammatory and tumour inhibitory properties of probiotics on mucosal polyamine levels. We investigated the effects of a high concentration multistrain probiotic for human use on colonic polyamine biosynthesis in dogs. Histological sections (inflammatory bowel disease, n=10; polyposis, n=5) were assessed after receiving 112 to 225×109 lyophilised bacteria daily for 60 days at baseline (T0) and 30 days after treatment end (T90). Histology scores, expression of PUT, SPM, ODC and DAO, and a clinical activity index (CIBDAI) were compared at T0 and T90. In polyps, cellular proliferation (Ki-67 expression), and apoptosis (caspase-3 protein expression) were also evaluated. After treatment, in inflammatory bowel disease significant decreases were observed for CIBDAI (P=0.006) and histology scores (P<0.001); PUT, SPM and ODC expression increased (P<0.01). In polyps, a significant decrease in polyamine levels, ODC activity, and Ki-67, and a significant increase in caspase-3 positivity and DAO expression (P=0.005) was noted. Our results suggest potential anti-proliferative and anti-inflammatory effects of the probiotic mixture in polyps and inflammation, associated with reduced mucosal infiltration and up-regulation of PUT, SPM, and ODC levels.

Objective To investigate the effect of sequential Helicobacter pylori eradication therapy on serum osteoprotegerin levels in patients with H. pylori infection and co-existing inflammatory bowel disease (IBD). Methods Three groups of patients were involved in this observational cross-sectional study: IBD (n = 83), H. pylori infection (HP, n = 68), and H. pylori infection with co-existing IBD (HP + IBD, n = 52). These groups were compared with a normal control group (NC, n = 50). Serum osteoprotegerin, serum bone alkaline phosphatase (BALP), and fecal calprotectin (FC) levels were measured. Results Serum osteoprotegerin levels were significantly correlated with the simple endoscopic score for Crohn’s disease and Mayo score for ulcerative colitis. The receiver operating characteristic analysis of osteoprotegerin revealed high values for the area under the curve, sensitivity, and specificity. Discriminant analysis illustrated that osteoprotegerin levels significantly differentiated patients with IBD from healthy controls. Osteoprotegerin and FC levels distinguished the IBD and HP + IBD groups from the NC and HP groups. Conclusions Sequential eradication therapy did not affect serum osteoprotegerin levels in patients with H. pylori infection and co-existing IBD. Serum osteoprotegerin elevation might be a marker for IBD development in patients with past or current H. pylori infection.

Abstract The effect of inflammatory bowel disease (IBD) on the density of galanin - immunoreactive (GAL-IR) nerve fibers was determined in the mucosa of canine duodenum, jejunum, and descending colon. Fiber density was evaluated by a single immunofluorescence method in biopsy specimens obtained from healthy dogs and patients with variable severity of the disease. The density of GAL-IR nerve fibers was determined by the semi-quantitative method by counting fibers in the field of view (0.l mm2). Fiber density was higher in dogs with moderate and severe IBD than in healthy animals. The results of the study suggest that GAL present in intestinal nerve fibers could play a role in the pathogenesis and development of canine IBD.

Abstract Background The prevalence of obesity and the number of bariatric surgeries in both the general population and in patients with inflammatory bowel disease (IBD) have increased significantly in recent years. Due to small sample sizes and the lack of adequate controls, no definite conclusions can be drawn from the available studies on the safety and efficacy of bariatric surgery (BS) in patients with IBD. Our aim was to assess safety, weight loss, and deficiencies in patients with IBD and obesity who underwent BS and compare findings to a control group. Methods Patients with IBD and a history of BS were retrospectively recruited to centers belonging to the Groupe d’Etude Thérapeutique des Affections Inflammatoires du Tube Digestif (GETAID). Patients were matched 1:2 for age, sex, body mass index (BMI), hospital of surgery, and type of BS with non-IBD patients who underwent BS. Complications, rehospitalizations, weight, and deficiencies after BS were collected in cases and controls. Results We included 88 procedures in 85 patients (64 Crohn’s disease, 20 ulcerative colitis, 1 unclassified IBD) with a mean BMI of 41.6 ± 5.9 kg/m2. Bariatric surgery included Roux-en-Y gastric bypass (n = 3), sleeve gastrectomy (n = 73), and gastric banding (n = 12). Eight (9%) complications were reported, including 4 (5%) requiring surgery. At a mean follow-up of 34 months, mean weight was 88.6 ± 22.4 kg. No difference was observed between cases and controls for postoperative complications (P = .31), proportion of weight loss (P = .27), or postoperative deficiencies (P = .99). Conclusions Bariatric surgery is a safe and effective procedure in patients with IBD and obesity; outcomes in this patient group were similar to those observed in a control population.
