Proceedings of the 29th European Paediatric Rheumatology Congress.

B Methods: b 21 patients were recruited in rheumatology centres in Flanders: 4 patients with oligo-articular JIA, 4 HLA-B27 SP + sp enthesitis-related JIA patients (JIA-ERA), 2 juvenile PsA patients, 4 adult PsA patients, 1 adult HLA-B27 SP + sp SpA patient, 3 RA patients, and 3 Lyme arthritis patients. In addition, incidental findings included one patient with a glandule pineal lesion, five patients with cysts, two patients with gliosis, one patient with optic neuritis, one patient with venous angioma, one patient with optic nerve atrophy and one patient with plexus papilloma. B Objectives: b to evaluate the levels of sTNF-RI and sTNF-RII in the blood sera of patients with sJA and monogenic autoinflammatory diseses(mAIDs) and their correlation with serum levels of commonly accepted markers of inflammation (C-reactive protein, Serum Amyloid A, Ferritin) B Methods: b 114 patients were included in the study, 43 of them with sJA(38%): male/female 20/23; age of inclusion in the study 3-19 years, FMF 33 (29%) patients; male/female 15/18; age 3-37 years, CAPS 23(20%)patients; male/female 15/8; age 1-51 years,, TRAPS 15(13%)patients; male/female 8/7, age 4-51 years. B Results: b The 28 patients enrolled were stratified into three subgroups based on the position of the variants on the NOD2 gene: N-Terminal (1 patient), Exon 4 (15 patients) and C-Terminal (12 patients). B Methods: b Eighty-three patients with CNO, nine patients with growth pain, nine patients with bone tumor, nine patients with juvenile idiopathic arthritis (JIA), and 30 healthy controls (HCs) who were followed up in Hacettepe University Pediatric Rheumatology Outpatient Clinics were included in the study.
