REVIEW
Anna Truszewska, Bartosz Foroncewicz, Leszek Pączek
Cell-free DNA (cfDNA) represents a small fraction of total DNA pool that circulates freely in the blood both in normal and pathological conditions. Data indicate that cfDNA plays an important role in the pathogenesis of systemic lupus erythematosus (SLE) and hypomethylation may be crucial for its immunogenic properties. Although differences in quantification methodology hinder the comparison of results between the studies, it appears that levels of cfDNA are abnormally elevated in SLE patients and correlate with various antibody titers, but not with disease activity...

OBJECTIVES: Neutrophils play a major role in rheumatoid arthritis (RA) pathogenesis. We aimed to evaluate if neutrophil DNA damage in RA patients is associated with the disease activity, autoantibodies status, carriage of the RA shared epitope (SE) and treatment. METHODS: DNA damage was assessed by alkaline comet assay in peripheral blood (77 patients and 55 healthy controls) and in 10 RA synovial fluid neutrophils. Evaluation of the respiratory burst of 30 patients with RA and 30 healthy controls was done...

OBJECTIVES: Based on a novel approach suggesting a role of adipose tissue in osteoarthritis (OA), we aimed to determine whether the infrapatellar fat pad (IFP) may affect joint cell functions through adipokines. METHODS: The conditioned media of IFP and subcutaneous adipose tissue from OA patients were used to determine the production of leptin and adiponectin, and to stimulate chondrocytes and fibroblast-like synoviocytes (FLS). Blocking experiments were carried out to evaluate the contribution of adipokines to IFP effects...

OBJECTIVES: We aimed to assess the outcome of a large Takayasu arteritis (TAK) cohort using the vasculitis damage index (VDI) and quality of life (QoL) scale, tools which have been validated for vasculitis. METHODS: Disease activity, damage and QoL were cross-sectionally evaluated in 165 TAK patients from 6 centres. SF-36 were applied to 51 age-matched healthy controls (HC). Persistent activity for ≥6 months was considered as treatment resistance (r-TAK). The correlation between VDI, clinical characteristics and mental (MCS)/physical (PCS) component scores of SF-36 were analysed...
