Megjegyzések:	The C1858T allele of the PTPN22 gene has been reported to confer risk for RA; but in some reports, the effect was restricted to RF- and/or anti-CCP-seropositive patients. Hungarian RA patients and matched controls were genotyped. The 1858T allele showed an increased prevalence in RA patients compared to controls. The 1858T allele represents a risk factor in the whole RA population (P = 0.001); an association was found both in RF-seropositive (P = 0.001) and anti-CCP-seropositive patients (P = 0.001), and in subjects with the combination of these factors (P = 0.002). In TT homozygotes, the estimated susceptibility to RA was more than double (OR = 5.04) of that seen in TC heterozygotes (OR = 1.89); the same gene dosage effect was observed in all seropositive RA subgroups. Our data show that the Hungarian RA patients belong to the populations in which the 1858T allele represents a susceptibility factor both in the RF- and/or anti-CCP-seropositive subjects, and the association exhibit a gene dosage dependency.

Megjegyzések:	Cardiovascular (CV) morbidity and mortality have been associated with rheumatoid arthritis (RA) and ankylosing spondylitis (AS). Natural autoantibodies (nAAb) are involved in innate immunity, as well as autoimmunity, inflammation, and atherosclerosis. There have not been any studies assessing the effects of biologics on nAAbs in RA and AS, also in relation to vascular pathophysiology. Fifty-three anti-TNF-treated RA and AS patients were included in a 12-month follow-up study. Anti-citrate synthase (CS) and anti-topoisomerase I fragment 4 (TOPO-F4) IgM and IgG levels were determined by ELISA. Ultrasonography was performed to assess brachial artery flow-mediated vasodilation (FMD), common carotid intima-media thickness (ccIMT), and arterial pulse-wave velocity (PWV). Other variables were also evaluated at baseline and 6 and 12 months after treatment initiation. Anti-TNF therapy improved FMD in RA and PWV in AS and stabilized ccIMT. TNF inhibition increased anti-CS IgM and IgG, and possibly also anti-TOPO-F4 IgG levels. Various correlation analyses revealed that nAAbs might be independently involved in autoimmunity as well as changes in inflammation and vascular pathology over time in biologic-treated patients (p < 0.05). We also found associations between anti-TOPO-F4 IgG and anti-Hsp60 IgG (p < 0.05). Baseline nAAb levels or nAAb level changes might determine changes in CRP, disease activity, FMD, PWV, and ccIMT over time (p < 0.05). The interplay between arthritis and inflammatory atherosclerosis, as well as the effects of anti-TNF biologics on these pathologies, might independently involve nAAbs.
