RESUMEN
OBJECTIVE: To analyse the effect of secukinumab on self-reported variables of patients diagnosed with psoriatic arthritis and/or ankylosing spondylitis in relation to their health status, pain, fatigue, sleep and quality of life. METHODS: A six-month, observational, longitudinal, prospective, multicentre study was conducted with 39 patients who initiated treatment with secukinumab as therapy for psoriatic arthritis and/or spondylitis. The main variables were changes in patient-reported measures and they were evaluated by means of the questionnaires: FACIT-fatigue, Insomnia Severity Index, EuroQol-3L-5D and PsAQoL. In addition, depending on the type of disease (peripheral psoriasis or spondyloarthritis) the DAS28 with ESR or the BASDAI were calculated, respectively. RESULTS: Levels of fatigue, moderate and severe insomnia significantly reduced after 6 months of treatment with secukinumab. At the same time, patient-reported quality of life increased significantly (Pâ¯=â¯.006). Data on pain and discomfort also show significant improvement after the treatment. CONCLUSIONS: Patients with psoriatic arthritis and/or ankylosing spondylitis who start treatment with secukinumab show improvement at 6 months in all effect sizes of the treatment, particularly in sleep, fatigue and quality of life. Furthermore, patient-reported outcome measures are of additional clinical value and allow more accurate and closer assessment of their real status of health and well-being.
