The Effects of Pilates Exercise Training Combined with Walking on Cardiorespiratory Fitness, Functional Capacity, and Disease Activity in Patients with Non-Radiologically Confirmed Axial Spondylitis.

The objective of the study was to examine the effects of Pilates exercise training combined with walking on cardiorespiratory fitness, functional capacity, and disease activity in patients with non-radiologically confirmed axial spondylitis (nr-axSpA). Thirty patients with nr-axSpA (seven women (90%), with a mean age of 46.07 ± 10.48 years old and C-reactive protein (CRP) 2.26 ± 2.14 mg/L) were randomly divided into two groups: A (n1 = 15 patients) and B (n2 = 15 patients). Group A followed a 6-month home-based Pilates exercise training program, while Group B remained untrained until the end of the study. A cardiopulmonary exercise test (CPET), timed up and go test (TUG), five times sit-to-stand test (5×STS), sit-and-reach test (SR), back scratch test for the right (BSR) and the left arm (BSL), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and Ankylosing Spondylitis Disease Activity Score (ASDAS) were applied to all patients, both at the beginning and at the end of the study. After 6 months, Group A showed higher values in exercise time by 37.41% (p = 0.001), higher peak oxygen uptake (VO2peak) by 25.41% (p = 0.01), a higher ratio between oxygen uptake and maximum heart rate (VO2/HRmax) by 14.83% (p = 0.04), and higher SR by 18.70% (p = 0.007), while lower values were observed in TUG by 24.32% (p = 0.001), 5×STS by 12.13% (p = 0.001), BASDAI score by 20.00% (p = 0.04) and ASDAS score by 23.41% (p = 0.03), compared to Group B. Furthermore, linear regression analysis showed a positive correlation in Group A between BASDAI and 5×STS (r = 0.584, p = 0.02), BASDAI and TUG (r = 0.538, p = 0.03), and ASDAS and 5×STS (r = 0.538, p = 0.03), while a negative correlation was found between BASDAI and VO2peak (r = -0.782, p < 0.001), ASDAS and SR (r = -0.548, p = 0.03), and ASDAS and VO2peak (r = -0.659, p = 0.008). To sum up, cardiorespiratory fitness, functional capacity, and disease activity improved after a long-term Pilates exercise training program in patients with nr-axSpA.

Real-world effectiveness of golimumab in adult patients with rheumatoid arthritis, psoriatic arthritis, and axial spondyloarthritis and an inadequate response to initial TNFi therapy in Greece: the GO-BEYOND prospective, observational study.

The impact of golimumab (GLM) on remission or low disease activity (LDA) was evaluated in patients with moderate-to-severe rheumatoid arthritis (RA), progressive psoriatic arthritis (PsA), or severe axial spondyloarthritis (axSpA), who failed previous treatment for their rheumatic disease with one initial tumor necrosis factor α inhibitor (TNFi). This is a multicenter, prospective, real-world observational 18-month study, conducted in Greece. The primary endpoint, assessed at 6 months, included the proportion of patients attaining LDA and/or remission (Disease Activity Score for 28 joints based on C-reactive protein [DAS28-CRP] ≤ 3.2), minimal disease activity (MDA; MDA criteria), and moderate disease activity (Bath Ankylosing Spondylitis Disease Activity Index [BASDAI] score 4-7), respectively. Other endpoints evaluated the persistence to GLM treatment and its impact on patients' work productivity (Work Productivity and Activity Impairment [WPAI] instrument) and quality of life (QoL; EuroQoL5 dimensions 3 levels [EQ-5D-3L] questionnaire). Descriptive statistics, the Wilcoxon signed-rank test, and Kaplan-Meier method were used for analyses. At 6 months, LDA was achieved by 46.4% of patients with RA, MDA by 57.1% of patients with PsA, and BASDAI 4-7 by 24.1% of patients with axSpA. For all study patients, persistence rates on GLM were high (85.1-93.7%) over 18 months; all WPAI domain scores and the EQ-5D-3L index score improved significantly (p < 0.001) from baseline to 18 months. GLM treatment was effective in patients with RA, PsA, or axSpA who had failed previous treatment with one TNFi and led to significant WPAI and QoL improvements. Persistence rates were high. Trial registration number and date of registration: As per the local regulations the study has been registered at the national registry for non-interventional studies https://www.dilon.sfee.gr/studiesp_d.php?meleti_id=MK8259-6995 .

Effectiveness and Safety of Certolizumab Pegol in Axial Spondyloarthritis in a Real-World Setting in Greece: A Sub-Analysis of the Prospective Non-Interventional CIMAX Cohort Study.

Objectives: We report the effectiveness and safety of certolizumab pegol (CZP) treatment in a real-world Greek axial spondyloarthritis (axSpA) population, including patients with radiographic (r-axSpA) and non-radiographic (nr-axSpA) disease. Methods: We performed a sub-analysis of the Greek cohort from CIMAX (NCT02354105), a multicentre, non-interventional cohort study that prospectively investigated CZP treatment in patients with axSpA. The primary outcome was change from baseline (CfB) in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) to Week 52. Results: Across 12 sites in Greece, 126 patients (r-axSpA: 91; nr-axSpA: 35) received ≥1 dose of CZP and were included in the Safety Set (SS), with 120 patients (r-axSpA: 86; nr-axSpA: 34) included in the Full Analysis Set (FAS). The mean (standard deviation [SD]) CfB in BASDAI at Week 52 was -3.8 (2.0) in the overall axSpA population, with numerically greater improvements observed for nr-axSpA patients compared with r-axSpA (nr-axSpA: -4.2 [2.1]; r-axSpA: -3.7 [2.0]). Improvements in the axSpA population, including r-axSpA and nr-axSpA subpopulations, were observed in key secondary and additional outcomes at Week 52. Overall, 14.3% (18/126) of patients in the axSpA population experienced ≥1 adverse event (AE). There were no serious AEs or deaths reported during the study. Conclusions: Patients with r-axSpA and nr-axSpA treated with CZP in clinical practice in Greece showed improvements in disease activity and key symptoms. CZP treatment may therefore help address the substantial health burden associated with axSpA in Greece.

Real-world evidence of the impact of adalimumab on work productivity and sleep measures in patients with rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis.

OBJECTIVE: Our aim was to evaluate the effect of adalimumab on work productivity measures, overall activity impairment, and sleep quality in patients with active moderate to severe rheumatoid arthritis (RA), psoriatic arthritis (PsA), or ankylosing spondylitis (AS) treated in routine care settings in Greece and determine factors associated with work impairment and sleep disturbance. METHODS: Patients with active moderate to severe RA (n = 184), PsA (n = 166), and AS (n = 150) were enrolled in this 24-month, prospective, observational study at 80 hospital outpatient clinics and private practices throughout Greece. Patients received adalimumab alone or in combination with standard antirheumatic therapies according to routine care. Work productivity and sleep were assessed through two patient-reported outcome measures: the Work Productivity and Activity Impairment-General Health questionnaire and the Medical Outcomes Study Sleep Scale (MOS-SS). Pearson correlation coefficients were estimated to assess the association of work impairment and sleep disturbances with disease activity scores. RESULTS: In the overall population, adalimumab significantly lowered absenteeism [mean (95% confidence interval) reduction, 18.9% (13.3-24.5%); n = 100]; presenteeism [40.0% (33.8-46.3%); n = 98], overall work productivity impairment [46.8% (40.4-53.2%); n = 94], activity impairment [47.0% (44.3-49.6); n = 421], and the MOS-SS sleep problems index [31.6 (29.5-34.1); n = 421] after 24-month treatment (p < 0.001). Significant improvements were also noted across the RA, PsA, and AS subpopulations (p < 0.05). Improvements in overall work impairment and sleep disturbance positively correlated with improvements in disease activity measures. CONCLUSION: Adalimumab improves work productivity and sleep problems while lowering disease activity in patients with moderate to severe RA, PsA, and AS managed in real-world settings.

Persistence and Adherence during the First Six Months of Tocilizumab Treatment Among Rheumatoid Arthritis Patients in Routine Clinical Practice in Greece. Results from the Single Arm REMISSION II Study (NCT01649817).

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.

In vivo study of pro-inflammatory cytokine changes in serum and synovial fluid during treatment with celecoxib and etoricoxib and correlation with VAS pain change and synovial membrane penetration index in patients with inflammatory arthritis.

OBJECTIVES: To determine the impact of celecoxib and etoricoxib therapy on serum and synovial fluid levels of IL-1ß, IL-6, TNF-α, sTNFR1, sTNFR2 and IL-1Ra in patients with inflammatory arthritis. To determine the correlation between cytokine changes and synovial membrane penetration index of the study drugs, and pain VAS change. METHODS: Fifty-one patients with inflammatory synovial fluid accumulation in a knee joint (33 women), randomized on 3 groups of 17 each: 100 mg b.i.d. celecoxib treated group, 90 mg o.d. etoricoxib treated group, and the control group with no NSAID treatment. Cytokines serum and synovial fluid levels as well as membrane penetration index were assessed prior and after treatment. RESULTS: Celecoxib led to decrease of both synovial fluid and serum levels of IL-6 (p=0.017 and p=0.003, respectively). In the etoricoxib treated group synovial fluid IL-6 concentration was significantly decreased after treatment (p=0.019). Correlating the study drugs penetration index with the change of cytokines and their receptors levels, positive correlation was found with the reduction of synovial fluid IL-1ß for the celecoxib (p=0.032) and with the increase of synovial fluid sTNFR1 for the etoricoxib group (p=0.028). Pain VAS reduction was positively correlated with decrease of synovial fluid IL-1ß (p=0.041) and IL-6 levels (p<0.005) and negative with synovial fluid sTNFR1 changes (p=0.045) in celecoxib group, and negative with serum TNF-α decrease (p=0.044) in the etoricoxib group. CONCLUSION: Our results suggest that celecoxib and etoricoxib inhibit the inflammatory cytokines, mostly in synovial fluid but also in serum, causing through this mechanism, decrease of inflammation, irrespective to COX-2 inhibition.

Intravitreal adalimumab for refractory uveitis-related macular edema.

OBJECTIVE: To evaluate the safety and efficacy of intravitreal adalimumab injections on refractory cystoid macular edema (CME) secondary to noninfectious uveitis. DESIGN: Prospective, noncomparative, interventional case series. PARTICIPANTS: Eight consecutive patients with controlled uveitis and chronic, refractory CME who had failed steroid treatment. INTERVENTION: Intravitreal adalimumab injections were given monthly for 3 months. MAIN OUTCOME MEASURES: Mean change in central retinal thickness (CRT) on optical coherence tomography (OCT); secondary objective was the mean change in best-corrected visual acuity (BCVA). RESULTS: Five of the eight patients completed the 6-month follow-up. For all 5 patients, the changes in BCVA from baseline to 3 months were not statistically significant (P=0.070). Similarly, the change in BCVA from baseline to 6 months was not statistically significant (P=1.0). The mean CRT at baseline was 692 microm. The changes from baseline to 3 months were not statistically significant (P=0.466); the changes from baseline to 6 months were also not statistically significant (P=0.808). We did not observe any ocular or systemic adverse effects. CONCLUSIONS: Intravitreal adalimumab showed no efficacy in improving BCVA or reducing CRT in patients with chronic uveitic macular edema.

Hypertrophic osteoarthropathy manifested with isolated calcaneal periostitis in bone scintigraphy.

Hypertrophic osteoarthropathy (HOA) is an incompletely understood syndrome characterized by digital clubbing and periosteal proliferation of long bones and it is commonly associated with primary lung tumors. Bone scintigraphy is a sensitive method in detecting HOA and characteristic findings have been reported. We present the case of a man with newly diagnosed non-small cell lung cancer, unremarkable clinical examination and blood tests and no digital clubbing. During disease staging, however, bone scintigraphy showed intense calcaneal cortical proliferation bilaterally without involvement of other parts of the skeleton. Cortical reaction of both calcanei resolved significantly after chemotherapy. This case indicates that HOA may manifest with isolated calcaneal periostitis bilaterally, which is a new addition to the literature.

Determination of two COX-2 inhibitors in serum and synovial fluid of patients with inflammatory arthritis by ultra performance liquid chromatography-inductively coupled plasma mass spectroscopy and quadrupole time-of-flight mass spectrometry.

The determination of two sulphur-containing drugs, the COX-2 inhibitors celecoxib and etoricoxib, in the serum and synovial fluid of inflammatory arthritis patients, is described using a sensitive ultra performance liquid chromatography-inductively coupled plasma mass spectroscopy (UPLC/ICPMS) method. Confirmation of the identity of the analytes in the samples was also performed by electrospray quadruple time-of-flight mass spectrometry in positive electrospray ionisation mode. The two COX-2 inhibitors were extracted from serum and synovial fluid following dilution with acetate buffer (pH 5) and liquid-liquid extraction (LLE) into ethyl acetate. Extracted samples were then analysed using UPLC/ICPMS with sulphur-specific detection. The limit of detection by UPLC/ICPMS was 0.45 ng/ml of sulphur in both serum and synovial fluid. The UPLC/ICPMS method was applied to the analysis of samples from patients receiving either 200 mg/day of celecoxib (2x 100 mg), 90 mg/day etoricoxib or placebo. The range of concentrations detected in the samples for the two drugs was from 0.3 to 3.3 microg/ml.
