REVIEW
Marina N Magrey, Muhammad A Khan
PURPOSE OF REVIEW: The purpose of the study is to briefly review the molecular mechanisms that leads to structural damage in ankylosing spondylitis (AS), defined as new bone formation resulting in complete or incomplete ankylosis of the spine, and the impact of treatment with biologics to retard this process. RECENT FINDINGS: The understanding of molecular mechanisms leading to new bone formation in AS has significantly improved but is still incomplete. Availability of biologics has greatly enhanced the treatment of patients with AS, but its impact on slowing the structural damage is still a matter of debate, although a few observational studies have shown that long term use of TNF-α blockers may slow radiographic progression...

Ankylosing spondylitis (AS) is a chronic systemic inflammatory disorder. It primarily affects the axial skeleton through involvement of the peripheral joint scan occurs. Temporomandibular joint (TMJ) involvement in AS varies from 4% to 35%. Here, we present a case of a 35-year-old male, follow-up of AS from last 8 years on nonsteroidal anti-inflammatory drugs, presented with fresh complaints of painfully restricted movements of jaw during swallowing. Computer tomography of patient demonstrates articular cartilage changes with disc and joint abnormalities...

The diagnosis of axial spondyloarthritis (axSpA) includes classical ankylosing spondylitis (AS) as well as earlier stages and abortive courses of the disease, in which structural alterations have not yet occurred. These are classified as non-radiographic axSpA (nr-axSpa). Inflammatory changes in the entire axial skeleton are characteristic for axSpA and can be visualized by magnetic resonance imaging (MRI), while in most patients structural alterations, such as new bone formation with syndesmophytes and ankylosis develop in the later course of the disease...

Axial spondyloarthritis (axSpA), which encompasses ankylosing spondylitis, is a complex genetic disease. Aberrant bone formation is a key feature of pathogenesis that can lead to ankylosis of the spine. Our objective is to determine, whether genes whose variants confer susceptibility to AS are expressed in bone progenitors like mesenchymal stem cells (MSCs). Since MSCs from bone marrow is difficult to obtain, we first examined, whether MSCs can be derived from induced pluripotent stem cells (iPSCs). Dermal fibroblasts of two axSpA patients and one healthy control were reprogrammed into iPSCs using a Sendai virus vector encoding pluripotency genes...

Inflammatory and chronic structural changes are objective signs of axial spondyloarthritis. In the sacroiliac joints (SIJs), inflammation (sacroiliitis) can be visualized as bone marrow edema, whereas chronic structural changes are visualized as fat metaplasia, erosions, sclerosis, or ankylosis in the area of the SIJ. In the spine, bone marrow edema in the vertebral bodies represents spondylitis but can also affect the facet and the costovertebral and costotransverse joints (arthritis), whereas structural changes are visualized as fat metaplasia, sclerosis or syndesmophytes and ankylosis at the vertebral edges...

PURPOSE: Chin-brow vertical angle (CBVA) is very important in correction of thoracolumbar kyphotic deformity in ankylosing spondylitis (AS), especially for the patients with cervical ankylosis. In previous study, Suk et al. stated that the patients with CBVA between -10° and 10° had better horizontal gaze. Unfortunately, in our clinical practice, we found the patients with CBVA between -10° and 10° after surgery usually complained of difficulty in cooking, cleaning, desk working and the like, although they had excellent horizontal gaze...

OBJECTIVE: We previously suggested that fibroblast-rich granulation tissue eroding the subchondral bone is instrumental in the joint remodeling that occurs in ankylosing spondylitis (AS). The purpose of this study was to determine if this granulation tissue also carries bone-forming capabilities, which we approached by searching for bone-forming cells (hypertrophic chondrocytes, osteoblasts) in its vicinity. We also assessed adipogenic tissue transformation, which has been suggested to be an intermediate feature in AS bone formation based on imaging studies...

Spondyloarthritis or spondyloarthropathy (SpA) is a multifactorial disease in which a disturbed interplay occurs between the immune system and environmental factors on a predisposing genetic background, which leads to inflammation and structural damage of target tissue. Many recent researches on development of SpA showed important role of innate and adaptive immunity as well as of prominent bone tissue remodeling which leads to osteoproliferation and ankylosis. It is believed that possible sites of inflammation in SpA are entheses, sinovium and gut...

OBJECTIVE: Ankylosing spondylitis (AS) is characterized by chronic inflammation leading to ankylosis, but also to low bone mineral density (BMD) and vertebral fractures (VFx). Treatment with tumor necrosis factor-α blockers decreases inflammation and has shown to be effective in increasing BMD. We studied the effects of etanercept (ETN) on BMD and VFx in patients with AS after 2 years of treatment. Further, we studied changes in bone turnover markers and radiological damage. METHODS: Patients with active AS, treated with ETN for 2 years, were included...

BACKGROUND: Ankylosing spondylitis (AS) is an immune-mediated arthritis particularly targeting the spine and pelvis and is characterised by inflammation, osteoproliferation and frequently ankylosis. Current treatments that predominately target inflammatory pathways have disappointing efficacy in slowing disease progression. Thus, a better understanding of the causal association and pathological progression from inflammation to bone formation, particularly whether inflammation directly initiates osteoproliferation, is required...
