A case-control study was conducted on patients with chronic periodontitis (CP) and healthy controls with the aim of evaluating possible association between interleukin17A (IL17A)G197A (rs2275913) andIL17FT7488C (rs763780) polymorphisms and periodontitis. Genotypes were determined by PCR-RFLP method. Statistical analyses were conducted using the OpenEpi and SNPStas software to calculate Chi-square with Yates correction or Fisher’s exact tests, odds ratios (OR), and 95% confidence intervals (CIs). SNPStas software was used to calculate Hardy-Weinberg equilibrium.IL17AAA genotype was more frequent in patients with chronic periodontitis (CP) in the codominant and recessive models (P=0.09; OR = 2.53 andP=0.03; OR = 2.46, resp.), the females with CP (P=0.01, OR = 4.34), Caucasoid patients with CP (P=0.01, OR = 3.45), and nonsmoking Caucasian patients with CP (P=0.04, OR = 3.51). TheIL17AA allele was also more frequent in Caucasians with CP (P=0.04, OR = 1.59).IL17FT7488C polymorphism was not associated with chronic periodontitis. In these patients from Southern Brazil, theIL17Ars2275913 polymorphisms,IL17AAA genotype, and the A allele were associated with a susceptibility to chronic periodontitis.

HLA-B*27 is an important marker for spondyloarthritis (SpA), however, many SpA patients are HLA-B*27 negative. Thus, the aim of this study was to investigate the influence of IL17, TNF and VDR gene polymorphisms in SpA patients who were HLA-B*27 negative. This case-control study was conducted in 158 patients [102 patients with ankylosing spondylitis (AS) and 56 with psoriatic arthritis (PsA)] and 184 controls. HLA-B*27 genotyping was performed using PCR-SSP and IL17A (rs2275913), IL17F (rs763780), TNF-308 (rs1800629), TNF-238 (rs361525), FokI C>T (rs2228570), TaqI C>T (rs731236), ApaI A>C (rs7975232), and BsmI C>T (rs1544410) using PCR-RFLP. Statistical analyses were performed by Chi-square and logistic regression using OpenEpi and SNPStats software. The IL17F C allele frequency was higher in patients with SpA, AS and PsA compared to controls. The IL17F T/C genotype frequency was higher in SpA patients in an overdominant inheritance model and when men and women were separately analyzed. IL17A_IL17F AC haplotype was significantly associated to the risk for SpA patients. As for VDR, the ApaI a/a was a potential risk factor for SpA in men. In conclusion, IL17F C variant contributed to the risk of SpA in Brazilian patients who were HLA-B*27 negative and could be a potential marker for SpA.

Genetic variations contribute to the susceptibility in the development of periodontitis. The aim of this study was to investigate the influence of IL18, IL12, and MMP9 polymorphisms in the chronic periodontitis. This case-control study involved 381 individuals matched by gender and age. Genotyping of IL18 (rs187238 and rs1946518) and IL12B (rs3212227) was performed by PCR-SSP and PCR-RFLP was used for MMP9 (rs3918242). IL-18 and MMP-9 were quantified in the serum by ELISA. SNPStats and OpenEpi software were used for statistical analysis and, in order to eliminate smoking as a confounding factor, the analyses were also performed in nonsmoking subjects. The IL18-137G/C genotype was associated with the risk of chronic periodontitis in nonsmokers (Pc=0.03; OR=1.99; overdominant inherence model). In the multivariate analyses, homozygous IL18-137G/G and IL18-607C/C were more frequent in males compared to women with these same genotypes (OR=2.51 and OR=3.30, respectively). The serum levels of the IL-18 in patients were higher than those in healthy controls (P=0.005). IL12B and MMP9 polymorphisms and MMP-9 serum concentration were similar in patients and controls. In this study, IL18 was associated with chronic periodontitis susceptibility. Men had greater risk than women for developing the disease when IL18 polymorphism was considered and the susceptibility was independent of the smoking status.

Background Data suggest that estrogen-metabolizing genes may be involved in breast cancer carcinogenesis. Objective The aim of this study was to determine the association of CYP1A1 and COMT polymorphisms with this disease. Material and methods: A pilot case-control study was conducted with Mexican women. Ninety-one breast cancer patients and 94 healthy controls were selected. Epidemiological and clinical questionnaires were answered by all participants, and genotyping data were obtained. CYP1A1 3801 T>C (rs4646903), CYP1A1 4889 A>G (rs1048943) and COMT 1947 G>A (rs4680) polymorphisms were analyzed by PCR-RFLP. Results The results showed a high risk of breast cancer in women carrying the CYP1A1 (3801 T>C) m2/m2 genotype (OR=2.52; 95%CI=1.04–6.08). The risk was higher in postmenopausal women (OR=3.38; 95%CI=1.05–10.87). No association between COMT 1947 G>A (rs4680) or CYP1A1 4889 A>G (rs1048943) and breast cancer was found. Conclusions This study suggests that the CYP1A1 (3801 T>C) m2/m2 genotype may contribute to breast cancer susceptibility in Mexican women.

Background:Cardiovascular disease (CV) is the most frequent cause of death in rheumatoid arthritis (RA) patients. It is well known that RA acts as an independent cardiovascular risk factor.Objectives:To assess the CV risk in RA patients using carotid ultrasonography (US) additionally to the traditional CV risk factors.Methods:A prospective transversal case control study was performed, including adult RA patients who fulfilled ACR/EULAR 2010 criteria and healthy controls matched according to CV risk factors. Population over 75 years old, patients with established CV disease and/or chronic kidney failure (from III stage) were excluded. The US evaluator was blinded to the case/control condition and evaluated the presence of plaques and the intima-media thickness. Statistical analysis was performed with R (3.6.1 version) and included a multivariate variance analysis (MANOVA) and a negative binomial regression adjusted by confounding factors (age, sex and CV risk factors).Results:A total of 200 cases and 111 healthy controls were included in the study. Demographical, clinical and US data are exposed in table 1. Not any difference was detected in terms of CV risk factors between the cases and controls. In both groups a relationship between age, BMI and high blood pressure was detected (p<0.001).Table 1.Table 2.RA basal characteristicsDisease duration (years)16,98 (11,38)Erosions (X-Ray of hands/feet)163 (81,5%)Seropositive (RF/anti-CCP)146 (73%)Extra-articular symptoms44 (22%)Intersticial difusse lung disease10 (5%)Rheumatoid nodules14 (7%)Prednisone use103 (51,5%)Median dose of Prednisone last year (mg)2,34 (2,84)sDMARDsMethotrexate104 (52%)Leflunomide29 (14,5%)Hydroxycloroquine9 (4,5%)bDMARDs89 (44,5%) TNFi41 (20,5%) Abatacept15 (7,5%) IL6i22 (11%) RTX11 (5,5%)JAKi26 (13%) Baricitinib11 (5,5%) Tofacitinib15 (7,5%)DAS 28-ESR3,1 (2,3, 3,9)SDAI7,85 (4,04, 13,41)HAQ0,88 (0,22, 1,5)RF (U/mL)51 (15, 164,25)Anti-CCP (U/mL)173 (22, 340)Patients showed higher intima-media (both right and left) thickness compared to controls (p<0.006). Moreover it was also related to the disease duration and DAS28 score (p<0.001). A higher plaque account was noted in cases(p<0.004) and it was also related to the disease duration (p<0.001).Conclusion:RA implies a higher CV risk. Traditional CV risk factors explains only partially the global risk. These findings support that RA acts as an independent cardiovascular risk factor.Disclosure of Interests:None declared

Background: Infusion reactions (IRs) are the most common adverse events (AEs) of infliximab (IFX) treatment in patients with inflammatory bowel disease (IBD). Prophylactic premedication (PM) with corticosteroids or antihistamines prior to IFX infusions has been used in clinical practice, but its efficacy is not known. The aim of this study was to assess the influence of steroid PM on IR incidence in pediatric patients with IBD receiving IFX. Methods: We performed a case–control study that included pediatric patients with IBD receiving IFX. Patients were divided into four subgroups according to the agent and PM they received: Remicade (original drug) + PM, and two biosimilars—Reshma +/− PM, and Flixabi—PM. At our site, until 2018, PM with steroids was used as a part of standard IFX infusion (PM+); however, since then, this method has no longer been administered (PM−). IRs were divided into mild/severe reactions. Differences between subgroups were assessed with the appropriate chi-square test. Multivariate logistic regression was used to assess associations between PM and IR incidence, correcting for co-medication usage. Results: There were 105 children (55 PM+, 44 male, mean age 15 years) included in the study who received 1276 infusions. There was no difference between the PM+ and PM− subgroups, either in incidence of IR (18.2% vs. 16.0% of patients, p > 0.05) or in percentage of infusions followed by IR (2.02% vs. 1.02% of infusions, p > 0.5). The OR of developing IR when using PM was 0.34, and the difference in IRs ratio in PM+ and PM− patients was not statistically significant (95% CI, 0.034–1.9). There were 11/18 (61.1%) severe IRs (anaphylactic shock) reported in all patients (both PM+ and PM−). Conclusion: At our site, the incidence of IR was low, and PM did not decrease the incidence of IR in pediatric patients with IBD receiving IFX. These results indicate that PM with steroids should not be a standard part of IFX infusion to prevent IR.

Citrullinated proteins have been suggested to play a critical role in the pathogenesis of multiple sclerosis (MS). Anticyclic citrullinated peptide (anti-CCP) antibody is used in the early diagnosis of rheumatoid arthritis (RA). The objective of this study was to investigate the presence of anti-CCP antibody in patients with MS compared to RA patients and healthy controls. Fifty patients with MS (38 females, 12 males; mean age 36.72 ± 8.82 years), 52 patients with RA (40 females, 12 males; mean age 40.87 ± 10.17 years), and 50 healthy controls (32 females, 18 males; mean age 38.22 ± 11.59 years) were included in this study. The levels of serum anti-CCP antibody were measured using an enzyme-linked immunosorbent assay (ELISA). The results of the study showed that anti-CCP antibody levels were significantly higher in RA patients versus MS or healthy controls(P<0.001). Moreover, anti-CCP antibody was positive in 43 (83%) patients with RA, while it was negative in all MS patients as well as in all healthy controls. Also, no significant correlation was found between the anti-CCP levels and EDSS scores(r=-0.250). In conclusion, the results of this study did not support a positive association between serum anti-CCP antibody and MS.
