Changes in Tumor Necrosis Factor Inhibitor Drug Survival in Patients With Rheumatoid Arthritis, Psoriatic Arthritis, and Ankylosing Spondylitis Over 15 Years.

Objective: To study changes in retention of first biologic disease-modifying antirheumatic drug (DMARD) therapy over a period of 15 years in an inception cohort of patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS).

Methods: We assessed patient and disease characteristics and drug survival of patients starting a biologic (tumor necrosis factor inhibitor [TNFi]) therapy between 2004 and 2019 in routine care at the Amsterdam Rheumatology and Immunology Center, Reade, the Netherlands. Starts were classified as early (2004-2008), intermediate (2009-2013), and recent (2014-2018).

Prevalence and Radiographic Progression of Hip Involvement in Patients With Ankylosing Spondylitis Treated With Tumor Necrosis Factor Inhibitors.

Objective: To examine the prevalence of hip involvement between sexes in patients with ankylosing spondylitis (AS) treated with tumor necrosis factor inhibitors (TNFi) and to estimate the effect of TNFi on radiographic progression of hip involvement compared to the spine.

Methods: Two hundred ninety-nine patients with AS treated with TNFi (215 men; median age: 43 yrs [IQR 36-52], median disease duration: 7.6 yrs [IQR 2-15]) were evaluated for hip involvement, defined radiographically as Bath AS Radiological Hip Index (BASRI-hip) score ≥ 2.

Long-Term Treatment With TNF-Alpha Inhibitors Improves Bone Mineral Density But Not Vertebral Fracture Progression in Ankylosing Spondylitis.

The aim of this cohort study was to evaluate the long-term effects of TNF inhibitors (TNFis) on BMD and the incidence of vertebral fractures (VFxs) in patients with ankylosing spondylitis (AS). Consecutive patients with active AS with TNFi treatment duration up to 4 years with available DXA scans and spine X-rays were included. BMD (classified according to the WHO criteria for osteoporosis) of the hip and lumbar spine, the VFx (classified as a Genant score >1/>20% height loss), and radiological progression (modified stoke ankylosing spondylitis spinal score [mSASSS]) scores were obtained at baseline and at 4 years of TNFi treatment.

Fat Mass Lowers the Response to Tumor Necrosis Factor-α Blockers in Patients with Ankylosing Spondylitis.

Objective: Our main objective was to assess the relationship between body composition (BC) and response to tumor necrosis factor-α (TNF-α) blocker treatment in patients with ankylosing spondylitis (AS). Our secondary objective was to evaluate the change of BC after treatment, accounting for sex and age.

Methods: All included patients fulfilled the modified New York criteria for AS and were naive to TNF-α blocker.

Muscle wasting in male TNF-α blocker naïve ankylosing spondylitis patients: a comparison of gender differences in body composition.

Objective: To assess gender differences in body composition (BC) in a cohort of AS patients naïve to TNF-α blockers.

Methods: Patients included fulfilled the Modified New York criteria for AS. Demographic information and disease activity measures (ASDAS and BASDAI) were reported.

Long-term treatment response in rheumatoid arthritis patients starting adalimumab or etanercept with or without concomitant methotrexate.

Objectives: To observe long-term clinical response and drug survival in a prospective two-year cohort study in rheumatoid arthritis (RA) patients starting adalimumab or etanercept treatment, with or without methotrexate (MTX), after failure of conventional DMARD therapy, including MTX.

Methods: Disease activity score of 28 joints (DAS28) and Health Assessment Questionnaire (HAQ) were collected of 873 consecutive RA patients, treated with adalimumab or etanercept, prospectively at baseline, 4, 16, 28, 40, 52, 78 and 104 weeks of biological therapy. Sustained minimal disease activity (MDA), DAS28 <2.

C-reactive protein polymorphisms influence serum CRP-levels independent of disease activity in ankylosing spondylitis.

Objectives: C-reactive protein (CRP) levels are frequently used to determine disease activity in patients with ankylosing spondylitis (AS), but these levels may not reflect disease activity. We therefore investigated the influence of common single-nucleotide polymorphisms (SNPs) in the CRP gene on CRP levels in AS patients. Additionally, the relation between CRP levels and BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) was examined.

Adalimumab significantly reduces the recurrence rate of anterior uveitis in patients with ankylosing spondylitis.

Objective: To investigate whether use of adalimumab decreases the frequency of attacks of anterior uveitis (AU) in patients with ankylosing spondylitis (AS).

Methods: Consecutive patients with AS, visiting an outpatient clinic and treated for at least 12 weeks with adalimumab, were enrolled. The number of attacks of AU in the year before start and during treatment were assessed by patient history and ophthalmological controls.

Effect of the application of trial inclusion criteria on the efficacy of adalimumab therapy in a rheumatoid arthritis cohort.

Objective: To evaluate the influence of inclusion criteria used in rheumatoid arthritis (RA) trials with adalimumab on clinical outcome and response.

Methods: The different inclusion criteria of published trials of adalimumab in RA were separately applied to a large prospective cohort of patients with RA treated with adalimumab (AdRA cohort), thereby mimicking patient selection for a clinical trial. Clinical response and outcome in the resulting 11 projection groups were compared using the 28-joint Disease Activity Score (DAS28) and time-averaged DAS28 as outcome measures of efficacy.

Beneficial effect of 1-year etanercept treatment on the lipid profile in responding patients with rheumatoid arthritis: the ETRA study.

Background: Effective anti-inflammatory treatment with tumour necrosis factor α (TNFα) inhibitors may have favourable effects on the lipid profile. Available evidence is derived from short-term studies, and it is not clear whether TNFα inhibitors have a similar effect on the lipid profile in responders and non-responders to the treatment.

Objectives: To investigate the effect of long-term etanercept treatment on the lipid profile in a large sample of patients with rheumatoid arthritis (RA), stratified for European League Against Rheumatism (EULAR) response.

Ankylosing spondylitis: a risk factor for myocardial infarction?

Objective: To ascertain the prevalence of myocardial infarction (MI) in ankylosing spondylitis (AS) relative to that in the general population.

Methods: A questionnaire was sent to 593 patients with AS, aged between 50 and 75 years and registered at the Jan van Breemen Institute or VU University Medical Centre. A total of 383 (65%) patients with AS returned their questionnaire that covered the primary outcome, (non-fatal) MI.

Decreasing incidence of symptomatic gastrointestinal ulcers and ulcer complications in patients with rheumatoid arthritis.

Background: Non-steroidal anti-inflammatory drugs (NSAIDs) frequently cause gastrointestinal (GI) ulcers and complications of ulcers. In 1997 in Amsterdam, the incidence of symptomatic GI events was 2.1% (95% CI 1.
