RESUMO
Objectives: This study aimed to investigate coronavirus disease 2019 (COVID-19) vaccination rates and factors affecting vaccination in children with rheumatic diseases. Patients and methods: This multicenter cross-sectional survey-based study was conducted between July 2022 and September 2022. Four hundred seventy-four patients (256 females, 218 males; median age: 15 years; interquartile range, 13 to 16 years) were included in the patient group, and 211 healthy children (124 females, 87 males; median age: 15 years; interquartile range, 13 to 16 years) were included in the control group. A questionnaire was administered to the parents face-to-face during routine outpatient visits. Results: Of the patients, 220 were followed up with the diagnosis of autoinflammatory disease, 174 with juvenile idiopathic arthritis, 48 with connective tissue disease, 23 with vasculitis, eight with uveitis, and one with sarcoidosis. In the study group, 256 (54%) patients and 115 (54.5%) healthy children received at least one dose of COVID-19 vaccine. Parents' concern regarding potential side effects of the vaccine was the most common reason for COVID-19 vaccination hesitancy in both groups. The median patient age, follow-up period, colchicine treatment rates, childhood vaccination and influenza vaccination rates, median parental age, parental vaccination rate, and parental education level were higher in vaccinated patients (p<0.001). Conclusion: Parents' concerns about safety and side effects were found to be the most important factors affecting vaccination success. Identification of the underlying causes of parental vaccine hesitancy will facilitate the development of effective vaccination strategies for potential future outbreaks.
RESUMO
OBJECTIVE: In this study, we aimed to evaluate the characteristics of pediatric rhupus patients including all the related series in the literature. METHODS: Thirty pediatric patients with rhupus syndrome from 12 different centers in Turkey were included in this study. The literature was also reviewed for pediatric patients with rhupus syndrome. RESULTS: The most prominent phenotype of these 30 patients was juvenile idiopathic arthritis (JIA) (60%) at the disease onset and SLE (73.3%) at the last visit. Major SLE-related organ involvements were skin (80%), hematological system (53.3%), and kidney (23.3%). Arthritis was polyarticular (73.3%), asymmetric (66.7%), and erosive (53.3%) in most patients. Hydroxychloroquine (100%), glucocorticoids (86.7%), and mycophenolate mofetil (46.7%) were mostly used for SLE, while glucocorticoids (76.6%), methotrexate (73.3%), and nonsteroidal anti-inflammatory drugs (NSAIDs) (57.6%) were mainly preferred for JIA. Our literature search revealed 20 pediatric patients with rhupus syndrome (75% were RF positive). The most prominent phenotype was JIA (91.7%) at the disease onset and SLE (63.6%) at the last visit. Major SLE-related organ involvements were skin (66.7%), hematological system (58.3%), and kidney (58.3%). Arthritis was polyarticular (77.8%), asymmetric (63.6%), and erosive (83.3%) in most patients. Glucocorticoid (100%), hydroxychloroquine (76.9%), and azathioprine (46.2%) were mostly used for SLE, while methotrexate (76.9%) and NSAIDs (46.2%) were mainly preferred for the JIA phenotype. CONCLUSION: Our study is the largest cohort in the literature evaluating pediatric rhupus cases. Most of the pediatric patients had polyarticular, asymmetric, and erosive arthritis, as well as organ involvements associated with SLE, including the skin, hematological system, and kidney.

AIM: The aim of this study was to investigate the frequency and type of FMF-associated inflammatory diseases in a large FMF pediatric patients and to compare them to those FMF patients without concomitant inflammatory diseases. MATERIALS AND METHODS: Familial Mediterranean fever patients enrolled in the Pediatric Rheumatology Academy (PeRA)-Research Group (RG) were included. The patients were divided into two groups according to concomitant inflammatory disease as FMF patients who had a concomitant inflammatory disease (group 1) and FMF patients who did not have a concomitant inflammatory disease (group 1). The clinical findings and treatments were compared between the two groups. RESULTS: The study group comprised 3475 patients with FMF. There were 294 patients (8.5%) in group 1 and 3181 patients (91.5%) in group 2. Juvenile idiopathic arthritis (n = 136) was the most common accompanying inflammatory disease. Arthritis, M694V homozygosity, and the need for biological therapy were more frequently observed in Group 1 (p < 0.05). Fever and abdominal pain were more frequently detected in Group 2 (p < 0.05). FMF patients with concomitant inflammatory diseas more frequently demonstrated colchicine resistance. There were no significant differences in the median attack frequency, chest pain, amyloidosis, erysipelas-like erythema, or family history of FMF between the two patient groups. CONCLUSION: To the best of our knowledge, this is the largest pediatric cohort reviewed to date. FMF patients may have different clinical profiles and colchicine responses if they have with concomitant inflammatory diseases. Key points ⢠FMF is associated with some inflammatory comorbidities diseases. ⢠To the best of our knowledge, this is the largest cohort evlauated pediatric FMF associated inflammatory comorbidities diseases reviewed to date.

OBJECTIVES: We aimed to outline the demographic data, clinical spectrum, and treatment approach of sarcoidosis in a large group of patients and sought to figure out the variations of early-onset (EOS) and late-onset paediatric sarcoidosis (LOS). METHODS: The study followed a retrospective-descriptive design, with the analysis of medical records of cases diagnosed as paediatric sarcoidosis. RESULTS: Fifty-two patients were included in the study. The median age at disease onset and follow-up duration were 83 (28.2-119) and 24 (6-48) months, respectively. Ten (19.2%) cases had EOS (before 5th birthday) and 42 (80.7%) cases had LOS. The most common clinical findings at the time of the disease onset were ocular symptoms (40.4%) followed by joint manifestation (25%), dermatological symptoms (13.5%), and features related to multi-organ involvement (11.5%). Anterior uveitis was the most common (55%) one among ocular manifestations. Patients with EOS displayed joint, eye, and dermatological findings more commonly than patients with LOS. The recurrence rate of disease in patients with EOS (5.7%) and LOS (21.1%) were not statistically different (P = .7). CONCLUSIONS: Patients with EOS and LOS may present with variable clinical features and studies addressing paediatric sarcoidosis cases in collaboration between disciplines will enhance the awareness of this rare disease among physicians and assist early diagnosis with lesser complications.

OBJECTIVES: Colchicine forms the mainstay of treatment in FMF. Approximately 5-10% of FMF patients are colchicine resistant and require anti-IL-1 drugs. We aimed to compare the characteristics of colchicine-resistant and colchicine-responsive patients and to develop a score for predicting colchicine resistance at the time of FMF diagnosis. METHODS: FMF patients (0-18 years) enrolled in the Turkish Paediatric Autoinflammatory Diseases (TURPAID) registry were included. The predictive score for colchicine resistance was developed by using univariate/multivariate regression and receiver operating characteristics analyses. RESULTS: A total of 3445 FMF patients [256 (7.4%) colchicine-resistant and 3189 colchicine-responsive) were included (female:male ratio 1.02; median age at diagnosis 67.4 months). Colchicine-resistant patients had longer, more frequent attacks and were younger at symptom onset and diagnosis (P < 0.05). Fever, erysipelas-like erythema, arthralgia, arthritis, myalgia, abdominal pain, diarrhoea, chest pain, comorbidities, parental consanguinity and homozygosity/compound heterozygosity for exon 10 MEFV mutations were significantly more prevalent among colchicine-resistant than colchicine-responsive patients (P < 0.05). Multivariate logistic regression analysis in the training cohort (n = 2684) showed that age at symptom onset, attack frequency, arthritis, chest pain and having two exon 10 mutations were the strongest predictors of colchicine resistance. The score including these items had a sensitivity of 81.3% and a specificity of 49.1%. In the validation cohort (n = 671), its sensitivity was 93.5% and specificity was 53.8%. CONCLUSION: We developed a clinician-friendly and practical predictive score that could help us identify FMF patients with a greater risk of colchicine resistance and tailor disease management individually at the time of diagnosis.

Objectives: The study aimed to determine the factors that increase the risk of disease flare in patients with juvenile idiopathic arthritis who stopped methotrexate (MTX) monotherapy following inactive disease (ID). Patients and methods: In the retrospective study, files of all juvenile idiopathic arthritis cases between April 1992 and June 2022 were examined. Patients who stopped MTX monotherapy following ID were evaluated. Patients with disease flare and persistent ID were compared. Juvenile idiopathic arthritis subgroup, age of symptom onset, autoantibodies, acute phase reactants, MTX method of use, and withdrawal strategy were recorded. Systemic juvenile idiopathic arthritis patients were excluded from the study due to different clinical symptoms, diagnosis, and treatment methods. Results: Files of 1,036 patients were evaluated, and 107 patients (88 females, 19 males; mean age: 5.9±4.2 years; range, 0.8-16.5 years) were included in the study. The median age at symptom onset was 4.8 (interquartile range [IQR]: 2-7.6) years. In terms of juvenile idiopathic arthritis subgroups, 52 (48.6%) had oligoarticular juvenile idiopathic arthritis, 43 (40.2%) had polyarticular juvenile idiopathic arthritis, and 12 (11.2%) had juvenile psoriatic arthritis. The patients reached ID in nine (IQR: 4.8-17.7) months after starting MTX, and MTX treatment was discontinued after one (IQR: 0.7-1.3) year following ID. The disease flare developed in 59 (55%) of the cases. The ID continued in 48 (45%) patients. In multivariate analysis, the risk of flare was associated with younger symptom onset (odds ratio [OR]=2.2, p=0.006), antinuclear antibody positivity (OR=1.6, p=0.03), higher erythrocyte sedimentation rate (OR=1.01, p=0.04), and C-reactive protein (OR=1, p=0.02) at the MTX onset. No difference was observed between the two groups regarding MTX dose, route of administration, prior and concomitant treatments, time to reach ID, and time and method of MTX discontinuation. Conclusion: In this study, the risk of flare was associated with patient's characteristics, rather than the administration and discontinuation method of MTX.
RESUMO
OBJECTIVE: To evaluate the safety of canakinumab using real-world data in patients with systemic juvenile idiopathic arthritis (sJIA) and autoinflammatory diseases (AID). RESEARCH DESIGN AND METHODS: This was a cross-sectional observational, multicenter study. Patients diagnosed with AID and sJIA treated with canakinumab were included in the study. The participating 13 centers retrospectively collected their patients' data. RESULTS: A total of 335 patients were involved in the study. Among these patients, 280 were in the AID group and 55 were in the sJIA group. Canakinumab was administered at a median dose of 3 (2.5-4) mg/kg. The median total exposure time to canakinumab was 1.9 (0.8-3.2) years, corresponding to 759.5 patient-years. Seven hundred and seventy-nine total adverse events (AE) were identified. The total incidence of AE, and serious adverse events (SAE) throughout the study period was 1.02 per patient-years. The upper respiratory tract infection rate was 0.7 per patient-years, while the other infection rate was 0.13 per patient-years. While no death was observed in any patient, SAE were observed in 8 patients. Interstitial lung disease, anaphylaxis, or anaphylactoid reactions were not observed in any patient. CONCLUSIONS: Real-life data from a large cohort of patients suggests that canakinumab is as safe as claimed in clinical trials.

Objectives: The aim of this study was to examine the clinical and phenotypic features of pediatric Behçet's disease (PEDBD) in our clinic and present the rates of fulfilling the diagnostic criteria. Patients and methods: Thirty-four patients (20 males, 14 females; mean age: 16.0±2.1 years; range, 10 to 18 years) diagnosed with PEDBD between January 2010 and December 2019 were retrospectively evaluated. Patients were reclassified according to 1990 International Study Group (ISG) criteria, 2014 International Criteria for Behçet's Disease (ICBD), and PEDBD criteria. Results: The mean age at diagnosis was 12.6±3.1 years, the median diagnosis delay time was 12.0 (range, 4.5 to 27.0) months, and the mean age at symptom onset was 10.8±2.9 years. The mean follow-up period was 31.9±20.9 months. Oral aphthous ulcer was observed in 33 (97.1%), genital ulcer in 16 (47.0%), ocular involvement in 15 (44.1%), skin lesion in 11 (32.3%), joint involvement in nine (26.4%), both vascular and neurological involvement in six (17.6%) patients. The pathergy test was positive in 11 (37.8%) patients, and human leukocyte antigen (HLA)-B51 was positive in 11 (78.5%) of 14 patients. The rates of patients meeting the criteria for ISG, ICBD, and PEDBD were 52.9%, 82.4%, and 50.0%, respectively. Conclusion: Pathergy and HLA-B51 can be used as supportive findings in patients who do not meet the diagnostic criteria. However, expert opinion is still the gold standard in diagnosis.
