Abstract

Abstract : Background: There is a paucity of epidemiological data in Early Arthritis. SIRENA is an Italian prospective observational study in SpA patients, naïve to conventional, targeted and biological DMARDs. Objectives: To present the baseline data, including demographic characteristics and patterns of clinical presentation, for the population enrolled between June 2017-February 2019. Methods: At the study entry, patients are diagnosed, newly or confirmed, according to ASAS criteria and classified in subjects with predominant axial (AX) or with mainly peripheral (PER) manifestations. Diagnostic delay, subtypes of SpA are evaluated as well as clinical features (i.e. presence of dactylitis, enthesitis, involvement of skin/nails/other organs). Results: In 23 italian sites, 282 patients were enrolled. Baseline data are shown in Table 1. 18% of the patients were obese (maximum BMI=39.7), 22% overweight. Diagnostic delay was registered for 58.1% patients with a mean delay of 57.1 months. Main reasons of the delay were incorrect referrals (44%) and previous misdiagnosis (27%). The most frequent type of SpA was psoriatic arthritis (54.3%), followed by ankylosing spondylitis (18.5%), undifferentiated SpA (11.5%), non-radiographic axial SpA (8.2%), and enteropathic SpA (7.5%). The majority of patients reported as first symptom peripheral arthritis and inflammatory back pain, followed by enthesitis. The most frequently reported comorbidities were psoriasis (50.4%) and cardiometabolic and gastrointestinal diseases (30.1% and 15.7%, respectively) - Table 2. To the 154 psoriatic arthritis (PsA) patients, CASPAR classification criteria were also applied, with a performance of 95% and a mean score of 3.64. Conclusion: SIRENA is the first Italian Disease Registry for SpA patients. The above results are in line with the few evidences found in literature (1), confirming the representativeness of our sample. In case of PsA, our results confirm that the accordance between ASAS and CASPAR criteria is very high. References: [1]Tayel et al. Rheumatol Int 2012; 32:2837-42.
