E25 The pattern of juvenile psoriatic arthritis in a tertiary centre in Libya
Bibliographic record
Abstract
Abstract Background Juvenile psoriatic arthritis (JPsA) is a relatively rare condition in childhood as it represents ∼5% of the whole Juvenile Idiopathic Arthritis (JIA). There are fewer reports describing the characteristics and outcome of patients with JPsA. Aim To describe the characteristic features and the treatment modalities of JPsA among Libyan children in pediatric rheumatology clinic at the Tripoli Children Hospital which is the only referral clinic covering the western, northern and southern part of Libya and to compare our results with other populations worldwide. Methods All the medical records of the children who were diagnosed to have JPsA according to ILAR classification criteria or Vancouver criteria (definite or probable) from January 2001 to January 2020 were included and retrospectively reviewed. Data were collected about demographic, clinical, and laboratory features and treatment Results The study included a total of 30 cases of JPsA that represents a 12% of total JIA cases over the study period, the mean age at presentation was 5.8 ± 5.3 years with male to female ratio of 1:1, with the mean duration of symptoms prior to diagnosis of JIA of 9 ± 10 months. The foremost common type of arthritis was peripheral polyarthritis (83% & 58.3%), with the Small joints commonly affected, 30% of patients had hip joint involvement. 13% of the patient had psoriasis, half of them before presentation of arthritis. Nail changes secondary to psoriasis was seen in 1 of the cohort, and the percentage of patients with dactylitis among the group was 30%. Family history of psoriasis found in 83% of the cohort, 26% found to be ANA positive. Chronic uveitis occurred in 10%. Patients of the total cohort, ANA positive, Unilateral anterior uveitis being the most common presentation. The following table summarizes the Medications used during the course of the disease At the time of the first visit 100%of total patients fulfilled the Vancouver criteria for juvenile PsA, While 5 of the12 patients didn’t fulfilled the ILAR criteria for JPsA. Conclusions Juvenile psoriatic arthritis constituted 12% of our patients with juvenile idiopathic arthritis. Juvenile psoriatic arthritis constitutes 8% to20% of JIA patients worldwide with equal gender distribution and peak age at presentation of 6–13 years. More than four peripheral joints involvement were the most frequent presentation. Half of the patients had skin involvement before the development of arthritis. Prevalence of chronic anterior uveitis was higher in our cohort than worldwide (10% vs 5% respectively) as an extra articular manifestation. All patients were treated with NSAIDs at presentation and/or during follow-up. Methotrexate was the most commonly used second-line agent Ethics Our study was approved by local ethical committee of pediatric department at Tripoli children hospital.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
