Background Spondylartritis (SpA) are usually observed in young patients and a clinical onset after 45 years is rare. The average life expectancy is getting longer and the proportion of late onset of SpA in rheumatology practice may became more common. SpA patients with late onset may have a distinctive clinical pattern in terms of functional impairment, extra-articular disease, co-morbidities and treatment status. Objectives The aim of this study was to compare the drug survival and effectiveness of tumour necrosis factor (TNF) inhibitors in patients with late onset SpA (LoSpA) compared with early onset SpA (EoSpA). Methods TReasure is a prospective, multicenter biological treatments registry from Turkey since 2016. It includes 15 different rheumatology centres. Patients with SpA fulfilling the ASAS criteria from TReasure database were divided into two groups as LoSpA (symptom onset >45 years of age) and EoSpA (symptom onset ≤45 years of age). Drug retention rates of first TNF inhibitors were calculated using the time until drug discontinuation independent of the reason that drug interruption. Specific reasons for discontinuing drugs were also assessed. Results Of 1382 SpA patients treated with TNF inhibitors, 9.4% (n=130) were included in the LoSpA and 90.6% (n=1252) were included in the EoSpA group. LoSpA had more female, enthesitis and psoriasis The median treatment duration was 53 months in LoSpA and 61 months in EoSpA. The baseline disease activity measures were similar except from ASDAS-ESH which is higher in LoSpA (table 1). The rate of major treatment response (BASDAI50) was lower in LoSpA than EoSPA at the last visit (26.1% vs 46.2%; p=0.009). Regarding the survival rates of TNF inhibitors, there was no significant difference between the patient groups (figure 1). The major cause of discontinuation in both of groups was drug ineffectiveness (68.6% in LoSpa and 60% in EoSpA, p>0.05). Conclusions LoSpA patients were almost 10% of all biological registry. LoSpA patients were predominantly female, and they had relatively higher baseline disease activity and lower biological treatment response. On the other hand the drug survival rate and discontinuation reasons of TNF inhibitors in the LoSpA group was comparable to that in the younger group.
