The effect of LILRB1 but not LILRA3 gene polymorphism in immunopathology of ankylosing spondylitis-A parallel to KIR genes.

LILR and KIR receptors recognize HLA-B27 and may influence immune response in ankylosing spondylitis (AS) development. Purpose of the study was to analyse LILRB1/LILRA3 polymorphisms in AS. We observed a possible protective effect of the T allele of LILRB1 rs1061680:T>C and no association with insertion/deletion polymorphisms of LILRA3 with AS.

ERAP1-ERAP2 haplotypes are associated with ankylosing spondylitis in Polish patients.

The objective of this case-control study was to evaluate the role of four single-nucleotide polymorphisms in the ERAP1 (rs2287987, rs30187, rs27044) and ERAP2 (rs2248374) genes and their haplotypes in predicting the risk for ankylosing spondylitis (AS) on a well-defined Polish population. Our study confirmed the strong association between the HLA-B*27 allele and the disease. For all tested ERAP1 SNPs we found significant differences in the minor allele and genotype distribution between patients and controls.

Disease activity in axial spondyloarthritis after discontinuation of TNF inhibitors therapy.

Objective: Use of tumour necrosis factor inhibitors (TNFi) has proved to be an important step forward in the treatment of axial spondyloarthritis (axSpA), but the duration of the therapy as well as the management in case of low disease activity (LDA) or remission are not clearly established. Currently, the identification of potential predictors associated with the treatment discontinuation is the basic purpose of many clinical studies. The aim of this study was to analyze the influence of the discontinuation of TNFi therapy on the disease activity in patients with low disease activity.

The variety of clinical presentations in IgG4-related disease in Rheumatology.

IgG4-related disease (IgG4-RD) belongs to the group of rare diseases in which the identification of the characteristic histology and immunohistochemistry provides with the gold standard in the diagnosis. The variable organ dysfunction reflects the clinical presentation. The examples of different IgG4-RD presentations in the Rheumatology Unit were discussed in this article.

Activity of JAK/STAT and NF-kB in patients with axial spondyloarthritis.

Background: The etiology of axial spondyloarthritis (axSpA) is not fully elucidated. Research continues in determining the mechanisms responsible for initiation of the disease process, its maintenance and development.

Objectives: The aim of this study was to evaluate the expression of transcription factors STAT (signal transducer and activator of transcription) and NF-κB (nuclear factor kappa B) as well as Janus kinase3 (JAK3) in the peripheral blood leukocytes.

Cytokine profiles in axial spondyloarthritis.

Objectives: Current studies concentrate on the cytokine network and its role in the pathogenesis of spondyloarthritis (SpA). In this study, we analyzed whether the serum cytokine profile (interleukins: IL-10, IL-11, IL-12, IL-15, IL-17, IL-23 and IL-33) correlates with demographic data, clinical manifestations, disease activity and treatment outcome in a group of patients with axial spondyloarthritis.

Material And Methods: Forty-nine patients with an established diagnosis of axial spondyloarthritis (aSpA) and 19 healthy volunteers as controls were enrolled in the study.

Does the KIR2DS5 gene protect from some human diseases?

Background: KIR2DS5 gene encodes an activating natural killer cell receptor whose ligand is not known. It was recently reported to affect the outcome of hematopoietic stem cell transplantation.

Methodology/principal Findings: In our studies on KIR2DS5 gene associations with human diseases, we compared the frequencies of this gene in patients and relevant controls.

[Analysis of efficacy and safety of multiple intravenous infusion of anti-tumor necrosis factor-alpha monoclonal antibody (Remicade) combined with methotrexate compared with sodium aurothiomalate and intramuscular depot methylprednisolone in rheumatoid arthritis].

The objective of the paper was compare the effects and tolerability of combined therapy of multiple intravenous infusions of anti-tumour necrosis factor-alfa (TNF-alfa) monoclonal antibody (Remicade) with methotrexate versus treatment with sodium aurothiomalate and intramuscular depot methylprednisolone in rheumatoid arthritis (RA). We investigate also the interval necessary to obtain the improvement in both treatment groups. 36 patients commencing intramuscular sodium aurothiomalate therapy with intramuscular depot methylprednisolone acetate at weeks 0, 4, 8 and 12 in addition to chrysotherapy were compared in retrospective analysis with 32 patients starting with multiple intravenous infusions of infliximab, anti-TNF-alfa monoclonal antibody (Remicade) and methotrexate at a stable dose.
