Abstract BackgroundKawasaki disease (KD) is a form of systemic febrile vasculitis that can be complicated by coronary artery lesions (CAL). A murine model of KD vasculitis showed that the vasculitis depended on intestinal barrier dysfunction, as well as that the tight junctions maintain the intestinal barrier. In this study, we aimed to investigate the role of tight junction Zonula occludens-1 (Zo-1) in intravenous immunoglobulin (IVIG) treatment response and the occurrence of CAL formation in KD patients.MethodsForty KD patients, 12 healthy controls, and 12 febrile controls were enrolled in this study. Tight junction ZO-1 levels were measured in sera by enzyme-linked immunosorbent assay.ResultsThe serum Zo-1 level was higher in the fever control group but did not achieve statistical significance. Patients who received a second dose of IVIG due to a failure to respond to the initial IVIG treatment had a higher serum tight junction Zo-1 level, but also without statistical significance (p value =0.0582). Patients who developed a coronary artery lesion had a lower serum tight junction Zo-1 level with statistical significance (p value =0.0275).ConclusionsTight junction ZO-1 levels decrease in KD patients with coronary artery lesions and are associated with the intestinal barrier dysfunction of Kawasaki disease and the occurrence of CAL in KD patients.

Abstract Background Kawasaki disease (KD) is a form of systemic febrile vasculitis that is complicated with coronary artery lesions (CAL). The tight junctions that maintain the intestinal barrier also play a role in systemic inflammatory diseases. Serum zonula occludens-1 (ZO-1) expression was found to be significantly lower in asthmatic patients, and another study reported that elevated systemic ZO-1 was positively correlated with inflammation in cirrhotic patients. A murine model of KD vasculitis demonstrated that vasculitis depended on intestinal barrier dysfunction, which is maintained by tight junctions. In this study, we aimed to investigate the role of the tight junction zonula occludens-1 (ZO-1) in the treatment response of intravenous immunoglobulin (IVIG) and the occurrence of CAL formation in KD patients. Methods We enrolled 40 KD patients, 12 healthy controls, and 12 febrile controls in this study. The serum levels of tight junction ZO-1 were determined by enzyme-linked immunosorbent assay. Results The serum ZO-1 level was higher in the fever control group but did not reach a statistical significance. KD patients who received a second dose of IVIG treatment due to initial IVIG unresponsiveness had a higher serum levels of tight junction ZO-1, but without statistical significance (2.15 ± 0.18 vs. 2.69 ± 0.31 ng/mL, p = 0.058). KD patients who developed a CAL demonstrated a significant lower serum tight junction ZO-1 levels than KD without CAL formation (1.89 ± 0.16 vs. 2.39 ± 0.15 ng/mL, p = 0.027). After multiple logistic regression analysis, ZO-1 levels [(95% confidence interval (CI): 0.058 ~ 0.941, odds ratio (OR) = 0.235, p = 0.041)] showed as the risk factor for CAL formation. Conclusion Serum levels of tight junction ZO-1 levels were lower in KD patients than fever controls and associated with CAL formation.

AbstractIntestinal oxidative stress produces pro-inflammatory cytokines, which increase tight junction (TJ) permeability, leading to intestinal and systemic inflammation. Cystine (Cys2) is a substrate of glutathione (GSH) and inhibits inflammation, however, it is unclear whether Cys2 locally improves intestinal barrier dysfunction. Thus, we investigated the local effects of Cys2 on oxidative stress-induced TJ permeability and intestinal inflammatory responses. Caco-2 cells were cultured in a Cys2-supplemented medium for 24 h and then treated with H2O2 for 2 h. We assessed TJ permeability by measuring transepithelial electrical resistance and the paracellular flux of fluorescein isothiocyanate–dextran 4 kDa. We measured the concentration of Cys2 and GSH after Cys2 pretreatment. The mRNA expression of pro-inflammatory cytokines was assessed. In addition, the levels of TJ proteins were assessed by measuring the expression of TJ proteins in the whole cells and the ratio of TJ proteins in the detergent-insoluble fractions to soluble fractions (IS/S ratio). Cys2 treatment reduced H2O2-induced TJ permeability. Cys2 did not change the expression of TJ proteins in the whole cells, however, suppressed the IS/S ratio of claudin-4. Intercellular levels of Cys2 and GSH significantly increased in cells treated with Cys2. Cys2 treatment suppressed the mRNA expression of pro-inflammatory cytokines, and the mRNA levels were significantly correlated with TJ permeability. In conclusion, Cys2 treatment locally reduced oxidative stress-induced intestinal barrier dysfunction possively due to the mitigation of claudin-4 dislocalization. Furthermore, the effect of Cys2 on the improvement of intestinal barrier function is related to the local suppression of oxidative stress-induced pro-inflammatory responses.

Abstract Objectives Kawasaki disease (KD) is an acute systemic vasculitis of unknown aetiology that affects infants and young children. Recent reports of elevated serum high mobility group box 1 (HMGB1) level during the acute phase of KD and its relationship to poor response to IVIG treatment suggest a possible association of HMGB1 polymorphisms with KD. We investigated the association between the polymorphisms of the HMGB1 gene, KD susceptibility, coronary artery lesions, and KD response to IVIG treatment. Methods Whole genome sequencing of the HMGB1 gene was performed to identify causative variants. Two tagging single nucleotide polymorphisms of the HMGB1 gene were selected using linkage disequilibrium analysis. The tagging single nucleotide polymorphisms were genotyped using the TaqMan Allelic Discrimination assay in a total of 468 subjects (265 KD patients and 203 controls). Results The HMGB1 single nucleotide polymorphisms were not associated with KD susceptibility. However, in KD patients, there was a significant association of rs1412125 with coronary artery lesions formation in the recessive model (GG vs AA + GA: odds ratio = 4.98, 95% CI = 1.69–14.66, P = 0.005). In addition, rs1412125 was associated with IVIG resistance in the recessive (GG vs AA + GA: odds ratio = 4.11, 95% CI = 1.38–12.23, P = 0.017) and allelic models (G vs A: odds ratio = 1.80, 95% CI = 1.06–3.06, P = 0.027). Conclusion The rs1412125 in HMGB1 might be a risk factor for the development of coronary artery lesions and IVIG resistance in KD patients.

Abstract Background: Kawasaki Disease (KD) is considered a major acquired heart disease in children under the age of 5. Coronary artery lesions (CAL) can occur in serious cases despite extreme therapy efforts. Previous studies have reported low serum albumin level was associated with disease outcome, but no further investigation was addressed yet. Method: This retrospective (case-control) study randomly included children with KD who were admitted and underwent laboratory tests before undergoing IVIG treatment in this institution, the largest tertiary medical center in southern Taiwan from 2012-2016. PNI, an albumin-based formula product, was evaluated as a predictor of CAL the first time. The progression of CAL was monitored using serial echocardiography for six months. We performed multivariable logistic regression analysis on the laboratory test and PNI with the disease outcome of the KD patients. Result: Of the 284 children, 158 had CAL, including transient dilatation, while the other 126 did not develop CAL during the 6-month follow-up period. A multivariate logistic regression model revealed that PNI and platelet count are significant predictors of CAL with a 95% confidence interval estimator of 2.532 (1.394-4.599) and1.004 (1.002-1.006), respectively. Using PNI to predict CAL presence gave an area under the receiver-operating-characteristics (ROC) curve of 0.596, and the PNI cut-off point is taken as 55.24, with a sensitivity of 0.509 and specificity of 0.678. Conclusion: This is the first study to demonstrate that PNI, an albumin-based formula product, is a useful index with clearly cut-off value for predicting CAL formation prior to initial IVIG therapy and thus warn clinicians to adopt aggressive therapeutic and coronary arteries imaging surveillance strategies before CAL can develop.

Introduction: There are several reports that coronary artery lesions (CALs) are increased/or not increased in patients who predominantly showed arthritis in patients with Kawasaki disease (KD). Patients with eczematoid skin lesions which seem like atopic dermatitis have not been reported in association with CALs. We intended to evaluate the risk of development of CALs in patients with two different phenotypes. Materials and methods: We retrospectively reviewed the medical records in 220 patients who diagnosed as KD and received IVIG treatment in Kyung Hee University Hospital at Gangdong from August 2006 to December 2013. In both patients groups (6 patients with arthritis and 52 patients with eczematoid skin lesion), we reviewed the state of coronary artery, clinical characteristics, associated viral or bacterial infections. Results: In patients with eczematoid lesions (52/220, 23.6%), the ages of patients were significantly older, the duration of fever was longer, and the prevalence of CAL was significantly higher than that of controls ( P =.000, P =.041, P =.033, respectively). In patients with arthritis (6/220, 3%), there were higher incidence of methylprednisolone or infliximab therapy ( P =.000, P =.004, respectively), and higher incidence of viral infection like influenza A and B, rhinovirus, parainfluenza 2, metapneumovirus, and coronavirus OC43 ( P =.018). Conclusions: The incidence of CAL was higher in group of eczematoid skin lesion in KD patients than in group of patients with arthritis. Associated viral infections were higher in arthritis group, therefore, it is better to find associated pathogens aggressively that might be a certain trigger of the development of KD in this group of patients.

Intestinal Dysbiosis

Background:While it is known that microbial dysbiosis is associated with the onset of rheumatoid arthritis, mechanistic insights how it facilitates the development of arthritis remained largely elusive to date. It is especially interesting how microbial dysbiosis affects the transition from asymptomatic autoimmunity to arthritis. We speculated that a breakdown of intestinal barrier function caused by microbial dysbiosis allows immune cells to shuttle from the gut to the joints.Objectives:To test whether intestinal barrier function is impaired before the onset of human RA and experimental arthritis and to seek for evidence that immune cells from the gut migrate to the joints.Methods:In a longitudinal cohort of RA-at risk individuals markers of disturbed intestinal barrier function, such as zonulin, were analysed and linked to RA onset. Furthermore, new-onset RA patients were assessed for gut leakiness and their intestinal biopsies for the expression of tight junction proteins and immune cell infiltration. In the murine model of collagen-induced arthritis, sequential analysis of intestinal dysbiosis, intestinal barrier function and arthritis onset was carried out. Additionally, barrier function was assessed on intestinal organoids exposed to faecal supernatants from eu- and dysbiotic mice with and without inhibition of zonulin. Furthermore, three types of interventions restoring intestinal barrier function were carried out for testing their effects on the inhibition of arthritis onset. Finally, photo- converted cells from the gut were traced in the joints to test for cellular trafficking from one to the other compartment.Results:Zonulin, a potent regulator for intestinal tight junctions, was elevated in autoimmune mice and men before the onset of arthritis and predicted the onset of human RA. Intestinal barrier functions as well as epithelial tight junctions were decreased before the onset of experimental arthritis and at onset of human RA. In mice, induction of autoimmunity was followed by rapid intestinal dysbiosis followed by gut leakiness before arthritis started. Faecal supernatants of arthritic mice induce epithelial barrier dysfunction in intestinal organoids in zonulin dependent manner. Restoration of the intestinal barrier in the pre-phase of arthritis using butyrate, CB1R agonist or zonulin antagonist larazotide inhibited the development of arthritis. Finally, using photoconvertible mice, gut-borne immune cells were identified that homed to the joints when barrier function was impaired.Conclusion:In summary, these data show the intestinal barrier dysfunction precedes the onset of RA and allows the trafficking of immune cells from the gut to the joints. Targeting of intestinal tight junction function may therefore allow preventing the onset of RA.Acknowledgments:Funded by the DFG-FOR2886 PANDORA, DFG–CRC118, Staedtler foundation, Johannes und Frieda Marohn-Stiftung, Else Kröner-Fresenius foundation, Interdisciplinary Centre for Clinical Research, Erlangen (IZKF), BMBF-MASCARA and the IMI funded projectRTCure.Disclosure of Interests:Mario Zaiss: None declared, Narges Taijc: None declared, Kerstin Sarter: None declared, Vugar Azizov: None declared, laura Bucci: None declared, Yubin Luo: None declared, Juan de Dios Cañete: None declared, francesco ciccia Grant/research support from: pfizer, novartis, roche, Consultant of: pfizer, novartis, lilly, abbvie, Speakers bureau: pfizer, novartis, lilly, abbvie, Georg Schett Speakers bureau: AbbVie, BMS, Celgene, Janssen, Eli Lilly, Novartis, Roche and UCB

Abstract Background Coronary artery lesions (CALs) are the most severe complication of Kawasaki disease (KD). Approximately 9–20% of the patients with KD develop CAL despite receiving regular treatment (intravenous immunoglobulin [IVIG] and aspirin). Some patients develop coronary aneurysms, leading to coronary artery stenosis or thrombosis, resulting in ischaemic heart disease and significantly affect the patients’ lives. The purpose of this study was to investigate the factors associated with the duration of CAL in patients with KD. Methods The data of 464 patients with KD and CAL admitted to the Children’s Heart Centre, The Second Affiliated Hospital and Yuying Children’s Hospital from 2010 to 2018 were retrospectively analysed. Demographic and clinical information and echocardiographic follow-up data were collected. Kaplan–Meier curves were used to estimate the overall CAL duration, and the log-rank test was used to compare statistical differences. Univariate and multivariate Cox regression models were used to identify variables related to the CAL duration. Results The median CAL duration was 46 days (95% confidence interval: 41–54 days). CALs were observed in 61.5, 41.5, 33.3, 22.3, 10.3, and 7.7% of the patients at 1 month, 2 months, 3 months, 6 months, 1 year, and 2 years after the onset of KD, respectively. Univariate Cox regression model showed that sex (p = 0.016), rash symptoms (p = 0.035), delayed IVIG treatment (p = 0.022), CAL type (p < 0.001), degree of CAL (p < 0.001), white blood cell count before IVIG treatment (p = 0.019), and platelet count after IVIG treatment (p = 0.003) were statistically significant factors associated with the overall CAL duration. Multivariable Cox regression showed that delayed IVIG treatment (p = 0.020), multiple dilatations (p < 0.001), a greater degree of dilatation (p < 0.001), and higher platelet count after IVIG treatment (p = 0.007) were positively related to CAL duration. Conclusions CAL duration was affected by delayed IVIG treatment, type of CAL, degree of CAL, and platelet count after IVIG treatment. These factors should be monitored carefully during the follow-up and management of patients with KD and CAL.
