RESUMEN
OBJECTIVE: To compare the 2-year retention rate between a second tumor necrosis factor alpha inhibitor (TNFi) and secukinumab (SEK) or ustekinumab (UST), in Psoriatic Arthritis (PsA) patients with previous inadequate response to their first TNFi. METHODS: Prospective longitudinal cohort study with a follow-up period of 2 years using the Nationwide Portuguese Reuma.pt database. Patients with a clinical diagnosis of PsA who also fulfill the CASPAR classification criteria, with previous treatment failure to a first-line TNFi and having started a second biotechnological drug (TNFi, SEK or UST) were included. The Cycling group was defined as switching from a first TNFi to a second TNFi, and the Swapping group as switching from a first TNFi to SEK or UST. Sociodemographic data, disease characteristics, disease activity scores and physical function at baseline and after 6, 12 and 24 months were recorded. Cox-proportional hazards regression was used to compare retention rates between Cycling and Swapping groups. To obtain a predictor model of 2-year discontinuation, a multivariable Cox regression model was performed. RESULTS: In total, 439 patients were included, 58% were female, with a mean age (standard deviation) of 49 (12) years. Globally, 75.6% initiated a second TNFi (Cycling group), and 24.4% started SEK/UST (Swapping group). The retention rates after 6, 12 and 24 months were 72%/66%/59% in the Cycling group; and 77%/66%/59% in the Swapping group. There were no significant differences in retention rates between both strategies (HR: 1.06, 95% CI 0.72-1.16). After 2 years of follow-up, 34.4% of patients discontinued their second biologic, mainly due to inefficacy (72.8%), with no differences found between groups. Baseline treatment with glucocorticoids was the only predictor of discontinuation after 2 years of follow-up (HR:1.668, 95% CI 1.154-2.409). CONCLUSIONS: After failure of a first TNF inhibitor, Cycling and Swapping strategies result in similar retention rates suggesting that both are acceptable in the management of patients with psoriatic arthritis.
RESUMEN
Introduction: The presence of another rheumatological condition in patients with systemic sclerosis (SSc) is not uncommon. To report a case of a patient with SSc-RA overlap and perform a review of the cases reported in the literature. Material and methods: A chart review of the present case report was performed. After, we performed a literature search in MEDLINE, EMBASE and Cochrane databases. Results: We included 26 articles. Sixty-three patients were reviewed, 51 were female with a mean age of 45.03 years at the time of the first diagnosis. Sixty-three patients were diagnosed with limited cutaneous SSc. Regarding organ involvement, the most frequently reported were cutaneous, vascular, pulmonary and gastrointestinal involvement. Erosions were presenting 65.08% of patients. A panoply of treatments was used. Conclusions: The authors concluded that screening for an associated disease should be encouraged since the overlap with SSc may affect prognosis and treatment.
