OBJECTIVES: We investigated whether polymorphisms (SNPs) in the promoter region of TNFA, or in the autoinflammatory TNFRSF1A and MEFV genes, concur with HLA-B27 in enhancing the risk of Spondyloarthritis (SpA) and/or in predicting the response to anti-TNFα treatment. METHODS: 373 controls and 137 SpA (82 with Psoriatic Arthritis-PsA and 55 with Ankylosing Spondylitis- AS; 98/137 under TNFα inhibitor therapy) from the Veneto Region (Italy) were studied. TNFA polymorphisms (-1031T>C;-857C>T;-376G>A;-308G>A;-238G>A) and HLA-B27 were assayed by RT-PCR...

Immune-mediated inflammatory diseases (IMIDs) are characterized by dysregulation of the normal immune response, which leads to inflammation. Together, they account for a high disease burden in the population, given that they are usually chronic conditions with associated co-morbidities. Examples include systemic lupus erythematosus, rheumatoid arthritis, Crohn's disease and type 1 diabetes. Since the advent of genome-wide association studies, evidence of considerable genetic overlap in the loci predisposing to a wide range of IMIDs has emerged...

BACKGROUND: Psoriatic arthritis (PsA) is a chronic inflammatory arthritis affecting approximately 2% to 3% of the population globally, and is characterized by both peripheral articular manifestations and axial skeletal involvement. Conventional therapies for PsA have not been fully satisfactory, though natural products (NPs) have been shown to be highly effective and represent important treatment options for psoriasis. PsA is a multigenic autoimmune disease with both environmental and genetic factors contributing to its pathogenesis...

BACKGROUND: In the last few decades, a better knowledge of the inflammatory pathways involved in the pathogenesis of Inflammatory Bowel Disease (IBD) has promoted biological therapy as an important tool to treat IBD patients. However, in spite of a wider spectrum of biological drugs, a significant proportion of patients is unaffected by or lose their response to these compounds, along with increased risks of infections and malignancies. For these reasons there is an urgent need to look for new pharmacological targets...

Chronic inflammatory diseases (CIDs), including Crohn's disease and ulcerative colitis (inflammatory bowel diseases, IBD), rheumatoid arthritis, psoriasis, psoriatic arthritis, spondyloarthritides, hidradenitis suppurativa, and immune-mediated uveitis, are treated with biologics targeting the pro-inflammatory molecule tumour necrosis factor-α (TNF) (i.e., TNF inhibitors). Approximately one-third of the patients do not respond to the treatment. Genetics and lifestyle may affect the treatment results. The aims of this multidisciplinary collaboration are to identify (1) molecular signatures of prognostic value to help tailor treatment decisions to an individual likely to initiate TNF inhibitor therapy, followed by (2) lifestyle factors that support achievement of optimised treatment outcome...

INTRODUCTION: Topical, systemic, oral disease modifying, and biologic agents are part of the armamentarium to manage psoriatic disease. The choice of therapy depends upon disease severity, relevant co-morbidities and patient preference. There is great variability in patient response with these agents, and there is still no clear method of selecting the preferred therapeutic agent for efficacy or lack of adverse events. AREAS COVERED: This article will review the pharmacogenetic and pharmacogenomic targets that are currently known with respect to psoriasis vulgaris, and the most frequent co-morbidity of psoriasis, psoriatic arthritis...

OBJECTIVES: We aimed to investigate the early changes in expression of C-type lectin domain family 9, member A (CLEC9A), a C-type lectin that is specifically expressed by the CD141(+) dendritic cell subset that is involved in cross-presentation to CD8(+) T cells, by evaluating gene and/or protein expression in three different compartments [skin, synovial tissue (ST) and serum] after short-term adalimumab treatment in PsA patients compared with placebo. METHODS: Patients with active PsA and psoriasis were randomized to receive adalimumab or placebo for 4 weeks...

OBJECTIVE: There is an increased interest in developing gene therapy approaches for local delivery of therapeutic genes in patients with arthritis. Intra-articular (i.a.) gene delivery, using an adeno-associated virus encoding a TNF soluble receptor, resulted in reduced paw swelling in an arthritis animal model, but i.a. treatment with a similar vector did not induce robust clinical improvement in patients. It is unclear whether this can be explained by for instance insufficient transduction efficiency or the fact that TNF is not a good therapeutic target for i...

TNF-blocking agents, non-biological disease-modifying anti-rheumatic drugs (nbDMARDs) and non-steroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed treatments in psoriatic arthritis. A large proportion of patients do not respond to these medications, although unfortunately clinically useful biomarkers that predict future response are currently lacking. Several candidate gene polymorphisms have been associated with responses to biologic therapies and nbDMARDs; however, replication and validation of these variants in large prospective psoriatic arthritis cohorts are required before translating these to clinical practice...

BACKGROUND: Genetic factors might have a role for lack of therapeutic response to anti-TNF-alpha agents, as previously suggested in patients with rheumatoid arthritis and inflammatory bowel disease. OBJECTIVES: We evaluated the role of the main TNF-alpha polymorphisms (-238G>A, -308G>A, -857C>T) in predicting the response to etanercept, an anti-TNF-alpha fusion protein. MATERIAL AND METHODS: Genomic DNA was extracted from buccal epithelial cells in a series of 97 psoriatic patients who received etanercept for at least 3 months...

P-glycoprotein (Pgp) is a transmembrane protein of 170 kD encoded by the multidrug resistance 1 (MDR-1) gene, localized on chromosome 7. More than 50 polymorphisms of the MDR-1 gene have been described; a subset of these has been shown to play a pathophysiological role in the development of inflammatory bowel disease, femoral head osteonecrosis induced by steroids, lung cancer and renal epithelial tumors. Polymorphisms that have a protective effect on the development of conditions such as Parkinson disease have also been identified...

OBJECTIVE: To our knowledge, there is no broad genomic analysis comparing skin and synovium in psoriatic arthritis (PsA). Also, there is little understanding of the relative levels of cytokines and chemokines in skin and synovium. The purpose of this study was to better define inflammatory pathways in paired lesional skin and affected synovial tissue in patients with PsA. METHODS: We conducted a comprehensive analysis of cytokine and chemokine activation and genes representative of the inflammatory processes in PsA...

OBJECTIVE: The immune inflammatory disorders rheumatoid arthritis (RA), psoriatic arthritis (PsA) and psoriasis (Ps) share common pathologic features and show responsiveness to anti-tumor necrosis factor (TNF) agents yet they are phenotypically distinct. The aim of this study was to examine if anti-TNF therapy is associated with divergent gene expression profiles in circulating cells and target tissues of patients with these diseases. METHODS: Peripheral blood CD14+ and CD14- cells were isolated from 9 RA, 12 PsA and 10 Ps patients before and after infliximab (IFX) treatment...

PURPOSE OF REVIEW: Various novel therapies for spondyloarthritis (SpA) are currently under development. In this review, we discuss the scientific rational to target the interleukin (IL)-23/IL-17 axis in SpA and give an overview of the proof-of-concept trials with drugs directed towards this axis. RECENT FINDINGS: Cumulative evidence from genetics (e.g. the strong genetic association with the IL-23 receptor gene), in-vitro models (e.g. the increased IL-23 production upon HLA-B27 misfolding), human expression studies (e...

Prolactin (PRL) is a hormone synthesized and secreted by lactotroph cells in the anterior pituitary gland. There is also extrapituitary hormone secretion by many cells, including cells of the immune system. In physiological conditions PRL is responsible for lactogenesis and other processes associated with it. PRL plays a significant role during the immune response as a cytokine, affecting proliferation and differentiation of many immune system cells. The biological effect of the hormone depends on binding with the specific prolactin receptor PRL-R, and activation of the transcription factors of targeted genes...

Over the past 2 decades, considerable progress has been made to further elucidate the complex pathogenesis of psoriasis, facilitating the development of a new armamentarium of more effective, targeted therapies. Despite these important advances, substantial deficits remain in our understanding of psoriasis and its treatment, necessitating further research in many areas. In the sixth section of the American Academy of Dermatology Psoriasis Guidelines of Care, gaps in research and care were identified. We discuss the most important gaps in research that currently exist and make suggestions for studies that should be performed to address these deficits...

Psoriatic arthritis (PsA) is a spondyloarthritis with a comorbid association with psoriasis. Without appropriate treatment it can be progressive, severe, deforming and destructive. It has long been recognized that subsets of PsA patients exist, characterized by different patterns of joint involvement. Associations between development of PsA and certain human leukocyte antigens (HLA) have been established. Evidence now suggests that progression of PsA is also genetically determined. The presence of one allele (HLA-B*27) has been associated with a distinct phenotype characterized by early joint involvement, whereas development of musculoskeletal symptoms is much slower in patients with another allele, C*06...

OBJECTIVES: To systematically review literature about the structure and function of nucleotide-binding oligomerization domain containing 2 (NOD2) and its disease association. METHODS: The English literature was searched using keywords "NOD2" and "disease". Relevant original and review articles were reviewed. RESULTS: NOD2 is an intracellular protein and shares similar molecular structure with NOD1, pyrin, and cryopyrin. There are more than 100 NOD2 gene mutations, some of which have been linked to diseases such as Crohn disease, Blau syndrome, and NOD2-associated autoinflammatory disease (NAID)...
