Abstract Aim This study explores the connection between Behçet’s disease (BD), characterized by persistent oral and genital ulcers alongside iritis, and periodontal disease. It examines the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and nitric oxide (NO) in gingival crevicular fluid (GCF) and saliva. Methods Forty Behçet’s patients with gingivitis or periodontitis and 47 patients with either gingivitis or periodontitis but without BD were studied. Periodontal status was recorded with standard clinical indexes. GCF and saliva samples were obtained. NO, IL-1β and TNF-α levels were analysed. Current Behçet’s symptoms and medications usage were recorded. Results Mean salivary IL-1β was elevated (p = .045), and mean NO level was decreased in BD patients with gingivitis compared to patients without BD (p = .000). In contrast, mean NO level in crevicular fluid was higher in Behçet’s patients with periodontitis than in patients without BD (p = .009). Furthermore, among Behçet’s patients, those with vascular involvement had lower salivary NO level compared to patients without vascular involvement (p = .000). Conclusions Based on our findings, the elevated levels of IL-1β in the saliva of Behçet’s patients with gingivitis, along with the decreased NO level, indicate an altered inflammatory response in the oral cavity.

ObjectiveInflammation has been associated with an increased risk for cancer development, while innate immune system activation could counteract the risk for malignancies. Familial Mediterranean fever (FMF) is a severe systemic inflammatory condition and also represents the archetype of innate immunity deregulation. Therefore, the aim of this study is to investigate the risk for cancer development in FMF.MethodsThe risk ratio (RR) for malignancies was separately compared between FMF patients and fibromyalgia subjects, Still’s disease patients and Behçet’s disease patients. Clinical variables associated with cancer development in FMF patients were searched through binary logistic regression.Results580 FMF patients and 102 fibromyalgia subjects, 1012 Behçet’s disease patients and 497 Still’s disease patients were enrolled. The RR for the occurrence of malignant neoplasms was 0.26 (95% Confidence Interval [CI.] 0.10-0.73, p=0.006) in patients with FMF compared to fibromyalgia subjects; the RR for the occurrence of malignant cancer was 0.51 (95% CI. 0.23-1.16, p=0.10) in FMF compared to Still’s disease and 0.60 (95% CI. 0.29-1.28, p=0.18) in FMF compared to Behçet’s disease. At logistic regression, the risk of occurrence of malignant neoplasms in FMF patients was associated with the age at disease onset (β1 = 0.039, 95% CI. 0.001-0.071, p=0.02), the age at the diagnosis (β1 = 0.048, 95% CI. 0.039-0.085, p=0.006), the age at the enrolment (β1 = 0.05, 95% CI. 0.007-0.068, p=0.01), the number of attacks per year (β1 = 0.011, 95% CI. 0.001- 0.019, p=0.008), the use of biotechnological agents (β1 = 1.77, 95% CI. 0.43-3.19, p=0.009), the use of anti-IL-1 agents (β1 = 2.089, 95% CI. 0.7-3.5, p=0.002).ConclusionsThe risk for cancer is reduced in Caucasic FMF patients; however, when malignant neoplasms occur, this is more frequent in FMF cases suffering from a severe disease phenotype and presenting a colchicine-resistant disease.

Objective Still’s disease is more frequently observed in the paediatric context, but a delayed onset is not exceptional both in the adulthood and in the elderly. However, whether paediatric-onset, adult-onset and elderly-onset Still’s disease represent expressions of the same disease continuum or different clinical entities is still a matter of controversy. The aim of this study is to search for any differences in demographic, clinical features and response to treatment between pediatric-onset, adult-onset and elderly-onset Still’s disease.Methods Subjects included in this study were drawn from the International AutoInflammatory Disease Alliance Network registry for patients with Still’s disease.Results A total of 411 patients suffering from Still’s disease were enrolled; the disease occurred in the childhood in 65 (15.8%) patients, in the adult 314 (76.4%) patients and in the elderly in 32 (7.8%) patients. No statistically significant differences at post-hoc analysis were observed in demographic features of the disease between pediatric-onset, adult-onset and elderly-onset Still’s disease. The salmon-coloured skin rash (p=0.004), arthritis (p=0.009) and abdominal pain (p=0.007) resulted significantly more frequent among paediatric patients than in adult cases, while pleuritis (p=0.015) and arthralgia (p

INTRODUCTION: Osteoarthritis is a disease characterized by joint cartilage damage, changes in surrounding bone structures and joint inflammation.Musculoskeletal ultrasonography is frequently used to evaluate soft tissue and joint in many rheumatologic diseases.We aimed tostudy the relationship between ultrasonographic findings and disease severity and quality of life in patients with knee osteoarthritis. METHODS: The knee joint of the patients included in the study was evaluated by ultrasonography.Womac index and EQ-5D questionnaire were used to evaluate the quality of life of the patients.The relationship between ultrasonography findings and womac and EQ-5D questionnaire was compared. RESULTS: Twenty-four patients were included in the study. 3 patients were male and 21 patients were female.There was no significant difference in synovial hypertrophy, effusion, baker cyst, calcification and womac score, VAS and EQ-5D score.A significant difference was found in the womac sub-parameter, stiffness parameter, in patients with osteophyte (p = 0.046).There was no significant correlation between Womac score and cartilage thickness.There was a negative correlation between womac and EQ-5D score (p = 0.006, r = -545).There was a negative correlation between VAS score and cartilage thickness (p = 0.017, r = -483). DISCUSSION AND CONCLUSION: In our study, no relation was found between USG findings and clinical complaints and quality of life. This may be related to the low number of patients. However, musculoskeletal ultrasonography is one of the most effective and inexpensive methods to show structural pathologies in the joint. The use of ultrasonography will continue to detect structural problems associated with osteoarthritis.

ObjectiveThe present manuscript aims to describe an international, electronic-based, user-friendly and interoperable patient registry for monogenic autoinflammatory diseases (mAIDs), developed in the contest of the Autoinflammatory Diseases Alliance (AIDA) Network.MethodsThis is an electronic platform, based on the Research Electronic Data Capture (REDCap) tool, used for real-world data collection of demographics, clinical, laboratory, instrumental and socioeconomic data of mAIDs patients. The instrument has flexibility, may change over time based on new scientific acquisitions, and communicate potentially with other similar registries; security, data quality and data governance are corner stones of the platform.ResultsAIDA project will share knowledge and expertise on mAIDs. Since its start, 118 centers from 24 countries and 4 continents have joined the AIDA project. Fifty-nine centers have already obtained the approval from their local Ethics Committees. Currently, the platform counts 337 users (122 Principal Investigators, 210 Site Investigators, 2 Lead Investigators, and 3 data managers). The Registry collects baseline and follow-up data using 3,748 fields organized into 21 instruments, which include demographics, patient history, symptoms, trigger/risk factors, therapies, and healthcare information for mAIDs patients.ConclusionsThe AIDA mAIDs Registry, acts both as a research tool for future collaborative real-life studies on mAIDs and as a service to connect all the figures called to participate. On this basis, the registry is expected to play a pivotal role in generating new scientific evidence on this group of rare diseases, substantially improving the management of patients, and optimizing the impact on the healthcare system.

Abstract Background Systemic sclerosis (SSc) is an autoimmune disease characterized by fibrosis of skin and lung as well as involvement of kidney, gastrointestinal system and heart. Aetiology and exact mechanism of disease is poorly understood. The association between antimicrobial peptides (AMPs) and other diseases such as idiopathic pulmonary fibrosis, diffuse panbronchiolitis, pulmoner alveolar proteinosis and psoriasis have been reported. A small number of studies have examined the role of AMPs on autoimmune diseases which has not been studied in scleroderma yet. We aimed to investigate AMP serum levels and their association with disease characteristics of SSc. Methods Forty-two patients (40 female, mean age 42 years) and 38 healthy subjects (32 female, mean age 38 years) were enrolled. For SSc patients, the following data were recorded: disease subset (limited/diffuse), autoantibodies (antinuclear, anti-centromere (ACA), and anti-SCL-70), blood tests, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP), modified Rodnan skin score, presence and history of digital ulcers, kidney, gastrointestinal disease and lung involvement assessed by computed tomography and pulmonary function tests. Association between serum AMPs and disease characteristics were analysed. Results Twenty-nine of the patients had diffuse (69%) and 13 of the patients had limited (31%) systemic sclerosis. Average disease duration was 5.5 years. Pulmonary involvement was detected in 20 patients (47.6%). Serum concentration of alpha defensin was higher than healthy subjects (563 ± 415 vs 377 ± 269 ng/mL, p = 0.02). However, no difference was observed for beta-1 and beta-2 defensins in SSc patients and healthy controls. In sub-group analysis patients with interstitial lung disease had higher levels of alpha defensin than those without lung involvement (684 ± 473 vs 430 ± 299 ng/ml, p = 0.04). There was also correlation between alfa defensin serum concentrations and CRP (r = 0.34). Conclusions Alpha defensin levels are increased in scleroderma patients and correlated with lung involvement indicating a role in the pathogenesis of disease. Trial registration This study is not a clinical trial study.

Abstract Background Granulomatosis with polyangiitis (GPA) is a granulomatous necrotizing vasculitis with high morbidity and mortality. Anti-neutrophil cytoplasmic antibody is a valuable diagnostic marker, however its titer lacks predictive value for the severity of organ involvement. Platelet to lymphocyte ratio (PLR) and mean platelet volume (MPV) has been regarded as a potential marker in assessing systemic inflammation. We aimed to explore the value of PLR and MPV in the assessment of disease activity and manifestations of disease in GPA. Methods 56 newly diagnosed GPA patients and 53 age-sex matched healthy controls were included in this retrospective and cross-sectional study with comparative group. Complete blood count was performed with Backman Coulter automatic analyzer, erythrocyte sedimentation rate (ESR) with Westergen method and C-reactive protein (CRP) levels with nephelometry. The PLR was calculated as the ratio of platelet and lymphocyte counts. Result Compared to control group, ESR, CRP and PLR were significantly higher and MPV significantly lower in GPA patients. In patients group, PLR was positively correlated with ESR and CRP (r = 0.39, p = 0.005 and r = 0.51, p

Background: We aimed to investigate coronavirus diease 2019 (COVID-19) outcomes in patients with amyloid A protein (AA) amyloidosis secondary to rheumatic diseases and discuss factors associated with disease course. Methods: A retrospective cohort was formed from adult patients with a diagnosis of AA amyloidosis. In patients with a positive severe acute respiratory syndrome coronavirus 2 polymerase chain reaction (PCR) test, rates of hospitalization, intensive care unit admission and mortality due to COVID-19 were collected from medical records. Data regarding to demographics, comorbidities, laboratory tests, medical treatments, adherence to previous treatments during COVID-19 and treatment administered for COVID-19 were collected from hospital databases and patient reviews. Results: In 96 patients with AA amyloidosis, 16 had COVID-19 with a positive PCR. Ten (62.5%) patients were hospitalized, 2 (12.5%) were admitted to ICU, 1 (6.25%) was died. Hospitalized patients tended to be older. Comorbidities seemed to be more frequent in hospitalized patients. None of the patients had rapid progression to end-stage renal disease post-COVID-19. Seven patients had pre-COVID-19 and post-COVID-19 proteinuria levels. Three had notable increase in proteinuria after COVID-19 in 2 of which amyloidosis treatment was revised accordingly. Conclusion: Despite high rates of hospitalization in AA amyloidosis patients, mortality was observed only in 1 patient. Progression of proteinuria requiring treatment adjustment may be an issue in these patients.

Background: Biomarkers of lung injury and interstitial fibrosis give insight about the extent of involvement and prognosis in well-known interstitial lung diseases (ILD). Serum Krebs von den Lungen-6 (KL-6) reflects direct alveolar injury and, transforming growth factor-beta1 (TGF-β1) and fibroblast growth factor-2 (FGF-2) are principal mediators of fibrosis in ILD and in almost all fibrotic diseases. In this sense, we aimed to assess associations of these biomarkers with traditional inflammatory markers and clinical course of COVID-19. Methods: Patients with COVID-19 who had confirmed diagnosis with SARS-CoV-2 nucleic acid RT-PCR were enrolled and followed up prospectively with a standardized approach one month after diagnosis. Patients were divided into severe and non-severe groups according to National Institutes of Health criteria. Outcome was assessed for the requirement of intensive care unit (ICU) admission, long term respiratory support and death. Blood samples were collected at enrollment and serum levels of KL-6, TGF-β1, FGF-2 were determined by ELISA. Association between these markers with other prognostic markers and prognosis were analyzed. Results: Overall 31 severe and 28 non-severe COVID-19 patients were enrolled and were compared with healthy control subjects (n = 30). Serum KL-6 levels in COVID-19 patients were significantly higher (median [IQR]; 11.54 [4.86] vs 8.54 [3.98] ng/mL, P = .001] and FGF-2 levels were lower (median [IQR]; 76.84 [98.2] vs 101.62 [210.6] pg/mL) compared to healthy control group. A significant correlation was found between KL-6 values and CRP, fibrinogen, d -dimer and lymphocyte counts. However, we did not find an association between these markers and subsequent severity of COVID-19, mortality and long-term prognosis. Conclusions: Serum KL-6 levels were significantly elevated at the diagnosis of COVID-19 and correlated well with the other traditional prognostic inflammatory markers. Serum levels of principal fibrosis mediators, TGF-β1, FGF-2, were not elevated at diagnosis of COVID-19, therefore did not help to anticipate long term prognosis.

Objective: To evaluate the cardiac involvement in patients with Still's disease with a focus on myocarditis included in the multicenter AIDA (AutoInflammatory Disease Alliance) network Still's disease registry. To exploit the predictive factors for myocarditis in deriving a clinical risk patient profile for this severe manifestation., Methods: A multicenter observational study was built up assessing consecutive patients with Still's disease characterized by the cardiac involvement among those included in the AIDA Network Still's Disease Registry. The cardiac involvement was defined according to the presence of pericarditis, tamponade, myocarditis, and/or aseptic endocarditis., Results: In total, 73 patients with Still's disease and cardiac involvement were assessed (mean age 36.3±19.9 years, 42.5% male sex); out of them, 21.9% were children. The most common cardiac manifestation was the pericarditis in 90.4% of patients, 26.0% presented with myocarditis, and less frequently endocarditis (2.7%) and tamponade (1.4%). Comparing clinical features of patients with myocarditis than others, significantly increased frequencies of skin rash, and pleuritis as well as higher values of systemic score were recognised. Furthermore, an enhanced mortality rate was registered in patients with myocarditis. In regression models, the skin rash and the systemic score independently predicted the myocarditis., Conclusion: The characteristics of patients with Still's disease and cardiac involvement were assessed in the AIDA network. The most common feature was the pericarditis but also a more severe clinical picture was reported in patients with myocarditis. The latter was associated with increased mortality rate and with higher systemic score, identifying patients to be carefully managed.
