Ankylosing Spondylitis (AS) is the prototype of a group of systemic rheumatic diseases collectively referred to as Spondyloarthitides (SpA). It is has recently become clear that AS is not as rare as previously thought and, although it has an early onset in life affecting patients in their reproductive years, it has not been proved to adversely affect fertility in females. Furthermore, new pharmaceutical agents have been introduced for its therapeutical management. The interaction between systematic rheumatic diseases and pregnancy has been under investigation with the majority of studies focusing on systemic lupus erythematosus and rheumatoid arthritis (RA)...

OBJECTIVE: To understand the limitations with current patient-reported outcome measures (PROM) used to generate quality-adjusted life-years (QALY) in rheumatology, and set a research agenda. METHODS: Two activities were undertaken. The first was a scoping review of published studies that have used PROM to generate QALY in rheumatology between 2011 and 2016. The second was an interactive "eyeball test" exercise at Outcome Measures in Rheumatology 13 that compared subdomains of widely used generic PROM, as identified through the scoping review, to subdomains of the Assessment of SpondyloArthritis Health Index (ASAS-HI) condition-specific PROM for ankylosing spondylitis...

OBJECTIVE: The interleukin 17 (IL-17) cytokine family is involved in a number of chronic inflammatory diseases. In spite of contradictory findings and a lack of causality in clinical studies, IL-17 inhibition for systemic lupus erythematosus (SLE) has regained attention as a potential therapeutic pathway, after demonstrating disease-modifying capabilities in ankylosing spondylitis. We investigated the clinical associations of interleukin 17 A (IL-17A) in patients with SLE. MATERIAL AND METHODS: A cross-sectional study was performed involving SLE patients (n=102; age: 49 years; 86% female) recruited from a regional registry...

Etanercept, a recombinant human tumor necrosis factor (TNF) receptor Fc fusion protein is an effective treatment option in adults with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis or plaque psoriasis and paediatrics with juvenile idiotypic arthritis and plaque psoriasis. Patent expiration in Europe and intense development of various etanercept products worldwide triggered a need for an international reference standard to facilitate determination of biological activity. Therefore, three candidate preparations of etanercept were lyophilized and evaluated in a multi-centre collaborative study comprising twenty eight laboratories from 15 countries for their suitability to serve as an international standard for the bioactivity of TNF receptor II Fc fusion proteins (international nonproprietary name, Etanercept)...

Patients treated with the TNF antagonist adalimumab develop anti-therapeutic antibodies (ATA), the prevalence of which varies depending on the assay used. Most assays are compromised due to the presence of adalimumab in the clinical samples. Our objective was to develop an antibody assay, applicable for clinical testing, which overcomes the limitation of therapeutic interference and to further determine the relationship between ATA development, adalimumab levels and disease activity in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) or ankylosing spondylitis (AS)...

Human major histocompatibility complex class I (MHC I) - or human leukocyte antigen (HLA) - proteins present intracellularly processed peptides to cytotoxic T lymphocytes in the adaptive immune response to pathogens. A high level of polymorphism in human MHC I proteins defines the peptide-binding specificity of thousands of different MHC alleles. However, polymorphism as well as the peptide ligand can also affect the global dynamics of the complex. In this study, we conducted classical molecular dynamics simulations of two HLA alleles, the ankylosing spondylitis (AS) associated/tapasin-dependent HLA-B*27:05 and nondisease-associated/tapasin-independent HLA-B*27:09, both in peptide-free forms as well as complex with four different peptides ligands...

We report the first documented case of retrobulbar optic neuropathy associated with golimumab. A 48-year-old man was admitted with a 3-week history of progressive visual loss of his left eye. He had received a second infusion of golimumab for ankylosing spondylitis 10 days before admission. A magnetic resonance imaging scan showed enhancement of both optic nerves and visual evoked potentials were consistent with demyelinating bilateral optic neuropathy, although visual acuity drop in the right eye could not be determined because of deep amblyopia...

BACKGROUND: Through mounting genetic investigations, it has been established that IL12B and IL23R gene single nucleotide polymorphisms have significant associations with autoimmune diseases including inflammatory bowel disease, psoriasis, and ankylosing spondylitis. IL-12/IL-23 pathway plays a pivotal role in etiopathogenesis of multiple sclerosis (MS), suggested by studies both in patients and animal models. METHODS: In a case-control study, 145 MS patients and 200 healthy subjects were genotyped for polymorphisms in IL12B and IL23R genes using Real-Time PCR allelic discrimination approach...

REVIEW
Michael Croft, Richard M Siegel
TNF blockers are highly efficacious at dampening inflammation and reducing symptoms in rheumatic diseases such as rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis, and also in nonrheumatic syndromes such as inflammatory bowel disease. As TNF belongs to a superfamily of 19 structurally related proteins that have both proinflammatory and anti-inflammatory activity, reagents that disrupt the interaction between proinflammatory TNF family cytokines and their receptors, or agonize the anti-inflammatory receptors, are being considered for the treatment of rheumatic diseases...

BACKGROUND: Programmed cell death protein 1 (PD-1) plays an important role in immune response regulation as a co-inhibitory signal during T cell activation. However, there is little known about the serum autoantibody profile of PD-1 in systemic lupus erythematosus (SLE), a disease characterized by the breakdown of immune tolerance to self-antigens and an excessive production of autoantibodies. Thus, we aim to investigate the serum levels and function of anti-PD-1 in patients with new-onset SLE...
