ABSTRACT

OBJECTIVE/AIM: One of the most important factors that affect a treatment's performance in rheumatoid arthritis (RA) is adherence to medications. According to literature, there are several reasons for non-adherence in RA patients with some of them being related to a specific patient profile of the study population. In this study, we investigated persistence to intravenous tocilizumab (TCZ) therapy in RA during routine clinical practice in Greece and identified causes for non-adherence. METHODS: 183 RA patients who mostly attended private practice Rheumatologists and received intravenous TCZ treatment at a schedule of 1 infusion per 4-weeks in the first 6 months were recorded retrospectively. RESULTS: Persistence estimated rate to TCZ therapy was 92.0% for patients that received 6 infusions and 83.4% for patients that received 7 infusions of TCZ. Potential factors that influence persistence to therapy were the occurrence of adverse events and response to the therapy. The main reasons for non-adherence to TCZ therapy were non-medically related with the most common being drug supply issues. The 6-month mean change from baseline in DAS28-ESR after initiation of TCZ therapy was -1.3, and the mean CDAI dropped from 29.6 at baseline to 16.7 at 6 months. Good/Moderate response was achieved by 89.1% of patients and remission by 23.5%. The safety profile was similar to that observed in other TCZ trials with the most common being infections, hematologic manifestations and musculoskeletal disorders. CONCLUSION: Overall, persistence to therapy appeared to be high in the rheumatology private practice setting and non-adherence to the TCZ treatment schedule is attributed mainly to non-medical reasons.

ABSTRACT

OBJECTIVE: To evaluate the prevalence of abnormal pulse wave velocity (PWV), pulse contour analysis (PCA) and abnormal ankle-brachial pressure index (ABPI) in patients with livedo reticularis (livedo) and without livedo. METHODS: We recruited 74 patients, of whom 41 had livedo: 16 APS, 9 APS with SLE and 16 with livedo (negative for aPL or lupus). The other group of 33 patients without livedo consisted of 10 APS, 8 APS with SLE and 15 with SLE only. Livedo was diagnosed and confirmed by a dermatologist. PWV was assessed in fasting patients by the Micro Medical PulseTrace analyser using a 4 MHz continuous-wave directional Doppler probe and digital PCA was analysed by Micro Medical PulseTrace by the same operator. Chi-square with Yates's correction was used for comparing results. RESULTS: The median age of the livedo patients was 46 (29-71) years and of the non-livedo patients was 45 (25-68) years. Abnormal values of PWV in 10/41 (24.40%), ABPI in 4/41 (9.8%) and PCA in 10/41 (24.40%) patients were observed in the livedo group and in the non-livedo group abnormal values of PWV in 1/33 (P ≤ 0.025), ABPI in 0/33 (P = NS) and PCA in 5/33 (P = NS) were observed. CONCLUSION: Patients with livedo reticularis are more likely to have abnormal PWV, indicating arterial stiffness.
