A clinical overview of paediatric sarcoidosis: Multicentre experience from Turkey.

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.

Do Pediatric Emergency Physicians Comply With Guideline Recommendations in Management of Patients With Acute Urticaria?

OBJECTIVES: To determine the level of knowledge and practical preferences of pediatricians regarding acute urticaria (AU) management and to assess the effects of training provided in accordance with the current urticaria guideline recommendations on pediatricians who work in the pediatric emergency department (PED). METHODS: A theoretical training was provided to pediatricians regarding the diagnosis and treatment of AU in line with current urticaria guideline recommendations. Before the training, pediatricians completed a 10-item questionnaire. This prospective study assesses their treatment approaches in patients admitted to PED because of AU during the 6-month period before and the 1-year period after training. RESULTS: Four hundred seventeen children in the pretraining and 1085 children in the posttraining periods were treated for AU in PED. Forty-eight pediatricians participated in the training. According to their questionnaire responses, 35% of them used only H1 antihistamine (AH) treatment, 50% used second-generation H1 AH (2nd-GAH) as AHs, 75% preferred the oral route of administration, and 85.4% did not administer systemic corticosteroid (sCS) to all patients. Comparing the practice approaches of the pediatricians in the pretraining and posttraining periods, first-generation H1 antihistamine (1st-GAH) preference rate decreased from 68.4% to 30.3% and the sCS preference rate decreased from 58.5% to 25.7%, while the 2nd-GAH preference rate increased from 31.7% to 69.7% (P < 0.001 for all). No treatments were prescribed for 10.8% of patients before the training and 3% after the training during discharge at home (P < 0.05). Comparing the home treatment choices of the pediatricians in the pretraining and posttraining periods, 1st-GAH preference rate decreased from 11.5% to 5%, while the 2nd-GAH preference rate increased from 78.7% to 91.5% (for both parameters, P < 0.001). CONCLUSIONS: Practical treatment preferences of pediatricians in the treatment of children with AU differ considerably from both current guideline recommendations and their own theoretical knowledge, and training can enhance pediatricians' compliance with current guideline recommendations.

Real-life data of etanercept efficacy and safety in juvenile idiopathic arthritis: a 24-month retrospective study at a single center.

OBJECTIVE: The aim of this study was to assess the efficacy and safety of etanercept (ETA) use in juvenile idiopathic arthritis (JIA). METHODS: The 24-month data of patients with JIA on etanercept in a single center were evaluated retrospectively. Response to treatment was assessed according to 10-joint Juvenile Arthritis Disease Activity Score (JADAS10), and JIA-American College of Rheumatology (ACR) improvement criteria. Safety assessments were based on adverse event (AE) reports. RESULTS: The study included 152 patients with JIA. The mean age at diagnosis of JIA was 8.5 ± 4.4 years, and treatment with ETA started at a mean age of 11.1 ± 4.4 years. The mean duration of ETA use was 16 ± 11.1 months. The mean JADAS10 score at baseline was 18.5 ± 5.9. By the third month, it had reduced to 8.6 ± 6.6 and by the sixth month to 5.7 ± 6. By the twelfth month, the JADAS10 score was 4.9 ± 6.7, and by the twenty-fourth month, it had worsened to 7.3 ± 7.8. ACR50 response was achieved in 79.6% of patients at 3 months, 67.1% at 6 months, 79.3% at twelfth months, 70.7% at the twenty-fourth month. During ETA treatment, 10 patients required hospitalization for serious infections. CONCLUSION: Etanercept is a safe and effective option for patients with JIA. However, variations in response between JIA subtypes highlight the need for individualized treatment strategies.

The cultural differences in transition assessment: Evaluation of TRANSITION-Q and STARx scales on Turkish rheumatic patients.

Objectives: This study aimed to assess the readiness of our patient population for the transfer to adult care and the applicability of the TRANSITION-Q and STARx scales to the Turkish adolescent patient population. Patients and methods: A total of 153 patients (92 males, 61 females; mean age: 15.5±1.9 years; range, 12 to 18 years) were included in the study between September 15, 2021, and December 15, 2021. The patients were divided into two groups according to age groups: 12 to 15 years old and 16 to 18 years old. The patients were also divided into four groups according to their diagnosis: connective tissue diseases, juvenile idiopathic arthritis, vasculitis, and autoinflammatory diseases. The TRANSITION-Q and STARx scales were administered face-to-face by a nurse and a doctor. The transition readiness of the patients was evaluated according to their scores. Results: Sixty-nine (45%) patients were in the 12 to 15 age group, and 84 (55%) were in the 16 to 18 age group. Eight-four (54.9%) patients had juvenile idiopathic arthritis, 47 (30.7%) patients had an autoinflammatory disease, 14 (9.2%) patients had vasculitis, and eight (5.2%) patients had a connective tissue disease. There was no significant difference in the scale scores according to disease groups and sexes in both scales. Considering the age of the patients, the mean scores of the patients in the 16 to 18 age group were found to be significantly higher compared to the 12 to 15 age group for both the TRANSITION-Q (74.3±13.3 vs. 65.4±9.6, p<0.001) and STARx scales (51.8±8.1 vs. 44.8±9.1, p<0.001). Cronbach's alpha score was 0.71 for the STARx scale and 0.79 for the TRANSITION-Q scale. Conclusion: TRANSITION-Q and STARx scales could guide the Turkish patient population in determining the pretransition needs of patients in planning individualized transition processes.

Real-life data on efficacy and safety of original Adalimumab and biosimilar Adalimumab (ABP 501) in pediatric rheumatic diseases.

BACKGROUND: We aimed to compare the efficacy and safety of the original product (OP) and biosimilar product (BP) of adalimumab in pediatric rheumatic diseases. RESEARCH DESIGN AND METHODS: The study group consisted of patients who had received original or biosimilar adalimumab (ABP 501) therapy for at least 3 months. The patients were divided into uveitis and arthritis groups based on the indication of adalimumab treatment. Assessment of disease activity was performed by Juvenile Arthritis Disease Activity Score in patients with juvenile idiopathic arthritis, and by standardization of uveitis nomenclature criteria in patients with uveitis. RESULTS: The study included 140 patients, of which 87 were treated with OP and 53 with BP. In the arthritis group, 26 (63.4%) and 20 (57.1%) patients reached inactive disease according to JADAS-27 in the original and biosimilar adalimumab groups, respectively. In the uveitis group the mean number of exacerbations throughout the treatment period was 0.84 ± 1.07 in the OP group, and 0.58 ± 0.79 in the BP group. There were 71 treatment-emergent adverse events in the OP group and 38 in the BP group. CONCLUSION: There was no significant difference between the biosimilar and the original product in efficacy and safety.

The assessment of autoinflammatory disease classification criteria (Eurofever/PRINTO) in a real-life cohort.

OBJECTIVE: The aim of the study was to determine the sensitivity and specificity rates of Eurofever/PRINTO autoinflammatory recurrent fever classification criteria with real-life data in patients with an autoinflammatory disease. METHODS: A total of 119 patients were included in the study. Based on clinical symptoms, they were divided into four subgroups: cryopyrin-associated periodic syndromes (CAPS), TNF receptor-associated periodic syndrome (TRAPS), mevalonate kinase deficiency (MKD), and syndrome of undifferentiated recurrent fever (SURF) using the Eurofever/PRINTO clinical classification criteria. In the last step, the patients were re-evaluated in the light of genetic results and their final diagnosis was reached. RESULTS: A total of 119 patients, including 37 CAPS, 13 TRAPS, 8 MKD, 39 SURF, 14 NLRP12-related autoinflammatory disease (NLRP12-AID), and 8 familial Mediterranean fever (FMF) patients were evaluated in the study. While the sensitivity of the new clinical Eurofever/PRINTO criteria was 48% for CAPS, 77% for TRAPS, 87.5%for MKD, and the specificity of the clinical criteria was 86% for CAPS, 85% for TRAPS, and 60% for MKD. The sensitivity of the new mixed (genetic plus clinical variables) Eurofever/PRINTO criteria was 27% for CAPS, 61% forTRAPS, 85% for MKD, and the specificity of the mixed criteria for each group was 100%. CONCLUSION: We found the sensitivity of the Eurofever/PRINTO classification criteria to be low as genotypic changes between populations cause phenotypic differences. For this reason, we think that patient-based evaluation is correct rather than standard classification criteria in real life. Key-points • In systemic autoinflammatory diseases, common variants in the populations may alter the phenotype, and making it difficult to classify some patients with the current classification criteria. • In populations with common genetic variants, the classification criteria should be modified according to the clinical phenotype.
