Overview

This study aimed to examine whether aerobic exercises, in addition to home exercises, have anti-inflammatory effects, which are evaluated by disease activity, acute phase reactants, and cytokine levels in axial spondyloarthropathy

Spondyloarthropathies (SpAs) are a group of chronic, inflammatory, and multisystemic diseases with common genetic, epidemiological, and clinical features. These diseases primarily involve the axial skeleton. The pathogenesis of SpA is multiple factors. The disease-specific inflammatory response, with the contribution of environmental factors based on genetic predisposition, is responsible for the pathogenesis of the disease.1 The main cytokines thought to be involved in the pathogenesis of axSpa are tumor necrosis factor-alpha (TNF-α), interleukin-17 (IL-17), IL-23, IL-22, IL-6, IL-7, interferon-gamma (IFN-γ), IL-12, and IL-26. There is no definitive marker associated with disease activity. Studies on cytokine levels and disease activity have shown that TNF-α, IL-6, IL-17, IL-23, and IFN-γ levels may be associated with disease activity in AS patients.4-9 Nonpharmacological and pharmacological methods are used together for the treatment of SpA. Non-pharmacological methods include patient education, smoking cessation, regular exercise, and physiotherapy practices. Aims of exercise therapy are to improve or preserve range of motion, flexibility, balance and to improve muscle strength and aerobic capacity. Posture, stretching, breathing, strengthening, and aerobic exercises are the most recommended in treating AS. Exercise therapy is described as the cornerstone treatment of axSpA by the European Alliance of Associations for Rheumatology (EULAR). Although patient compliance with exercise therapy is not easy, the advantages of exercise are that it is cheap, low-risk, and easy to apply compared to pharmacological treatments. The anti-inflammatory effects of exercise have recently been discussed. Few studies have investigated the anti-inflammatory effects of exercise in patients with AS. While some of these studies showed significant improvement in disease activity, functional status, flexibility, and CRP with aerobic exercise in patients with AS, some did not. Although a few studies have shown a significant decrease in TNF-α levels in AS patients with non-aerobic exercise programs, no study has examined the changes in TNF-α and IL-17 levels with aerobic exercise treatment. The primary aim of our study was to examine whether aerobic exercise, in addition to the home exercise program, has an anti-inflammatory effect in patients with axSpA, as evaluated by disease activity, acute phase reactants, and cytokine levels. Our secondary aim was to determine whether aerobic exercise, in addition to home exercise, has a positive effect on functional status, functional exercise capacity, quality of life, NSAID consumption, chest expansion, and spinal mobility.

Outcomes

Primary Outcomes

ASDAS-CRP

The Ankylosing Spondylitis Disease Activity Score (ASDAS) is an index to assess disease activity in Ankylosing Spondylitis (AS). The prefered score uses CRP. ASDAS-CRP = 0.12 x Back Pain + 0.06 x Duration of Morning Stiffness + 0.11 x Patient Global + 0.07 x Peripheral Pain/Swelling + 0.58 x Ln(CRP+1) Back pain, patient global assessment, duration of morning stiffness and peripheral pain/swelling are all assessed on a numerical rating scale (from 0 to 10). The 3 cut-offs selected to separate these states were: \<1.3 between "inactive disease" and "moderate disease activity", \<2.1 between "moderate disease activity" and "high disease activity", and \>3.5 between "high disease activity" and "very high disease activity". Cut-offs for improvement scores were: a change ≥1.1 units for "clinically important improvement"

Time frame: 12 weeks

Tumor necrosis factor-alpha (TNF-α)

TNF-α is a chemical messenger produced by the immune system that induces inflammation. Its relation with axial spondyloarthropathy's disease activity is uncertain but inhibition of TNF-α is one of the targets of current therapies. There were no cut-off measures for TNF-α on axial spondyloarthropathy patients.

Time frame: 12 weeks

Interleukin-17 (IL-17)

IL-17 is a pro-inflammatory cystine knot cytokines. They are produced by a group of T helper cell known as T helper 17 cell in response to their stimulation with IL-23. Its relation with axial spondyloarthropathy's disease activity is uncertain but inhibition of IL-17 is one of the targets of current therapies. There were no cut-off measures for IL-17 on axial spondyloarthropathy patients.

Time frame: 12 weeks

C-reactive protein (CRP)

CRP is an annular (ring-shaped) pentameric protein found in blood plasma, whose circulating concentrations rise in response to inflammation. It is an acute-phase protein of hepatic origin that increases following interleukin-6 secretion by macrophages and T cells. On axial spondyloarthropathy patients it may be elevated but in some patients there could be no elevation of CRP. Also it is necessary for ASDAS-CRP calculation.

Secondary Outcomes

Pain Visual Analogue Scale (VAS)

The visual analogue scale (VAS) is a psychometric response scale that can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured. We use the 0-10 cm VAS to measure patients' pain severity. We used 0 as no pain and 10 as unbearable pain.

The Bath Ankylosing Spondylitis Functional Index (BASFI)

The Bath Ankylosing Spondylitis Functional Index was named for the location of the institution (Bath, England) where authors A. Calin and co-workers developed this validated index to determine the degree of functional limitation in patients with the inflammatory autoimmune disease Ankylosing Spondylitis (AS). we used BASFI for the patients' functional assessment. BASFI measured by answering a questionaire which has 10 questions about activities of daily life, bending, lie down, position changes, climbing stairs, standing abilities. Then gathered points divided by 10. High scores represents low functional state.

Time frame: 12 weeks

Bath Ankylosing Spondylitis Metrology Index (BASMI)

BASMI used for all the patients who are attended to our study to assessment of the spinal mobility. BASMI has 3 point scale. BASMI is the most applicated and effective method to assessment of axial mobility. It has five different clinical measurements which are cervical rotation, tragus wall distance, lumbar flexion, trunk lateral flexion, and intermalleolar distance. High scores are associated with poor spinal mobility

Time frame: 12 weeks

Chest expansion measurement

Chest expansion is based on the difference between the chest circumference measurement after a deep inspiration at the level of the 4th intercostal space and the chest circumference measurement after a forced expiration. The normal value of chest expansion may vary depending on age and gender. It is expected to be at least 5 cm in young healthy individuals.

Time frame: 12 weeks

6 minute walk test (6 MWT)

6 MWT was used to evaluate the functional exercise capacity of the patients participating in the study. While doing 6 MWT, the patients is asked to go as fast as they can between the marked points on at least 30 meters of flat ground, but not to run. Standard commands are used during the test. The total walking distance is recorded for 6 minutes. An increase of 30 meters in 6 MWT is thought to indicate clinical improvement.

Time frame: 12 weeks

Ankylosing Spondylitis Quality of Life (ASQoL)

The ASQoL scale was used in the evaluation of the patients participating in the study. This scale consists of 18 questions that can be answered "yes" or "no". 1 point is given for a "yes" answer and 0 point is given for a "no" answer. At the end of the test, all scores are added up. Numerically high results indicate a low quality of life.
