We report two cases of siblings presenting coexisting non-radiographic axial spondyloartrhritis and joint hypermobility syndrome, complaining of back pain with morning stiffness, enthesitis, peripheral arthralgia, high erythrocyte sedimentation rate and C-reactive protein level and positive HLA-B27. The association of these two conditions is rare, but especially interesting in view of their contrasting features, one causing axial skeleton stiffness, the other a wider range of peripheral joint movements. Coexistence of these two opposite disorders causes confusion in diagnosis and management, resulting in lower quality of life for patients, as they are in pain from the early stages...

KIR3DL2 is a member of the killer cell immunoglobulin-like receptor (KIR) family that was initially identified at the surface of natural killer (NK) cells. KIR3DL2, also known as CD158k, is expressed as a disulfide-linked homodimer. Each chain is composed of three immunoglobulin-like domains and a long cytoplasmic tail containing two immunoreceptor tyrosine-based inhibitory motifs. Beside its expression on NK cells, it is also found on rare circulating T lymphocytes, mainly CD8(+). Although the KIR gene number varies between haplotype, KIR3DL2 is a framework gene present in all individuals...

OBJECTIVE: The strong genetic association between HLA-B27 and ankylosing spondylitis has been known for over 40 years. HLA-B27 positivity is possibly associated with severity of ankylosis. We studied the in vitro and in vivo impact of HLA-B27 in models of chondrogenesis and osteogenesis. METHODS: Different in vitro differentiation systems were used to mimic endochondral and direct bone formation. ATDC5 cells and primary human periosteum-derived cells (hPDCs) were transduced with lentiviral vectors expressing HLA-B27 or HLA-B7...

BACKGROUND: Poncet's disease is a rare syndrome characterized by articular impairment in a form of rare tuberculid. One of the theories of its cause involves an autoimmune response induced by the intravesical administration of the Calmette-Guerin Bacillus or the treatment of bladder carcinoma. Furthermore, there may be an appearance of oligoarticular or polyarticular arthritis, beginning 1-3 months after the start of therapy. Few physicians know the disease and the literature related to that syndrome is scarce and restricted to case reports, which contributes to its under diagnosis...

Human leukocyte antigen (HLA) class I ligands and Killer immunoglobulin-like receptors (KIRs) regulate the cytolytic activity of natural killer (NK) cells and certain T cells. We examined their genetic predisposition to disease susceptibility and clinical phenotypes in Taiwanese ankylosing spondylitis (AS) patients. KIR genotyping and Human Leucocyte Antigen C (HLA-C) sequencing were performed in 653 Taiwanese AS patients and 952 healthy controls. KIR genotype distributions and HLA-C allele frequencies were compared in patients and controls and among patients with and without HLA-B27 positivity, early age onset and spinal syndesmophytes...

Acute anterior uveitis (AAU) is the most frequent uveitis subtype. It is often associated with HLA-B27 and with inflammatory rheumatic diseases, in particular with spondyloarthritis (SpA), which itself is strongly associated with HLA-B27. About 40-60% of patients with AAU have an associated spondyloarthritis, and 20-40% of patients with spondyloarthritis also have uveitis. The incidence of AAU in patients with SpA clearly correlates with disease duration. The AAU has an acute onset, usually affects only one eye at a time, and shows a tendency for recurrence...

Spondyloarthritides are of a group of inflammatory rheumatic diseases, with negative rheumatoid factor, associated with the HLA-B27 gene. They comprise ankylosing spondylitis, psoriatic arthritis, reactive arthritis, and enteropathic-related spondylitis. The presence of sacroiliitis represents the most characteristic feature of these disorders and is an important criterion in diagnosis. Nonradiographic axial spondyloarthritis is a new classification concept. Conventional radiography is recommended as the first imaging method to diagnose sacroiliitis and different entities and to monitor established structural changes...

The genetic factors associated with susceptibility or resistance to viral infections are likely to involve a sophisticated array of immune response. These genetic elements may modulate other biological factors that account for significant influence on the gene expression and/or protein function in the host. Among them, the role of the major histocompatibility complex in viral pathogenesis in particular human immunodeficiency virus (HIV) and hepatitis C virus (HCV), is very well documented. We, recently, added a novel insight into the field by identifying the molecular mechanism associated with the protective role of human leukocyte antigen (HLA)-B27/B57 CD8(+) T cells in the context of HIV-1 infection and why these alleles act as a double-edged sword protecting against viral infections but predisposing the host to autoimmune diseases...

The human leukocyte antigen class I gene HLA-B27 is the strongest risk factor for Ankylosing Spondylitis (AS), a chronic inflammatory arthritic disorder. More recently, the Endoplasmic Reticulum Aminopeptidases (ERAP) 1 and 2 genes have been identified by genome-wide association studies (GWAS) as additional susceptibility factors. In the ER, these aminopeptidases trim the peptides to a length suitable to fit into the groove of the MHC class I molecules. Noteworthy, an epistatic interaction between HLA-B27 and ERAP1, but not between HLA-B27 and ERAP2, has been highlighted...

BACKGROUND: Few studies have investigated the impact of obesity on the response to tumor necrosis factor inhibitors (TNFi) in patients with axial spondyloarthritis (axSpA). The aim of our study was to investigate the impact of different body mass index (BMI) categories on TNFi response in a large cohort of patients with axSpA. METHODS: Patients with axSpA within the Swiss Clinical Quality Management (SCQM) program were included in the current study if they fulfilled the Assessment in Spondyloarthritis International Society (ASAS) criteria for axSpA, started a first TNFi after recruitment, and had available BMI data as well as a baseline and follow-up visit at 1 year (±6 months)...

The definition of axial involvement in psoriatic arthritis (PsA) is still under debate. Currently, the axial spondyloarthritis (SpA) criteria defined by Assessment of Spondyloarthritis International Society (ASAS) may be the most adequate.(1) The aims of present study were to assess axial involvement according to ASAS criteria in an observational PsA cohort and define the clinical characteristics more associated with this kind of involvement. Our study included consecutive patients who had a visit in a tertiary Rheumatology centre...

OBJECTIVE: To estimate sacroiliac joint radiographic (X-SIJ) progression in patients with axial spondyloarthritis (axSpA) and to evaluate the effects of inflammation on MRI (MRI-SIJ) on X-SIJ progression. METHODS: X-SIJ and MRI-SIJ at baseline and after 2 and 5 years in patients with recent onset axSpA from the DESIR cohort were scored by three central readers. Progression was defined as (1) the shift from non-radiographic (nr) to radiographic (r) sacroiliitis (by modified New York (mNY) criteria) or alternative criteria, (2) a change of at least one grade or (3) a change of at least one grade but ignoring a change from grade 0 to 1...

BACKGROUND: Axial spondyloarthritis (AxSpA) is a relatively frequent and debilitating disease, with a prevalence ranging from 0.1 to 2% in the Caucasian population. Current Assessment of Spondyloarthritis International Society (ASAS) classification criteria of AxSpA rely either on sacroiliitis on imaging plus one SpA feature or positive HLAB27 antigen plus two SpA features, in a patient with chronic low back pain and age at onset of less than 45 years. Therefore, HLA-B27 is a central feature in SpA classification and plays a pivotal role in referral strategies and early diagnosis...
