Clinical and Sonographic Pattern of Late-Onset and Early-Onset Rheumatoid Arthritis: Comparative Study

Abstract

Patients with LORA demonstrated more active synovitis and a higher frequency of erosions compared with those with EORA, despite the non-significant difference in DAS 28 scores. Moreover, patients with LORA exhibited a greater burden of comorbidities than those with EORA. Therefore, regular evaluation of inflammatory activity using MSUS, along with assessment of associated comorbid conditions, is recommended in patients with LORA.
