Megjegyzések:	Objectives: HLA-DRB103 is strongly associated withanti-Jo-1-positive idiopathic infl ammatory myopathies (IIM)and there is now increasing evidence that Jo-1 antigen ispreferentially expressed in lung tissue. This study examinedwhether smoking was associated with the development ofanti-Jo-1 antibodies in HLA-DRB103-positive IIM.Methods IIM cases were selected with concurrentinformation regarding HLA-DRB1 status, smoking historyand anti-Jo-1 antibody status. DNA was genotypedat DRB1 using a commercial sequence-specifi coligonucleotide kit. Anti-Jo-1 antibody status wasestablished using a line blot assay or immunoprecipitation.Results 557 Caucasian IIM patients were recruited fromHungary (181), UK (99), Sweden (94) and Czech Republic(183). Smoking frequency was increased in anti-Jo-1-positive IIM cases, and reached statistical signifi cance inHungarian IIM (45% Jo-1-positive vs 17% Jo-1-negative,OR 3.94, 95% CI 1.53 to 9.89, p<0.0001). A strongassociation between HLA-DRB103 and anti-Jo-1status was observed across all four cohorts (DRB103frequency: 74% Jo-1-positive vs 35% Jo-1-negative, OR5.55, 95% CI 3.42 to 9.14, p<0.0001). The frequency ofHLA-DRB103 was increased in smokers. The frequencyof anti-Jo-1 was increased in DRB103-positive smokersvs DRB103-negative non-smokers (42% vs 8%, OR 7.75,95% CI 4.21 to 14.28, p<0.0001) and DRB103-positivenon-smokers (42% vs 31%, p=0.08). In DRB103-negative patients, anti-Jo-1 status between smokers andnon-smokers was not signifi cantly different. No signifi cantinteraction was noted between smoking and DRB103status using anti-Jo-1 as the outcome measure.Conclusion Smoking appears to be associated withan increased risk of possession of anti-Jo-1 in HLADRB103-positive IIM cases. The authors hypothesisethat an interaction between HLA-DRB103 and smokingmay prime the development of anti-Jo-1 antibodies.

Cím:	Functional variants of interleukin-23 receptor gene confer risk for rheumatoid arthritis but not for systemic sclerosis / Farago, B., Magyari, L., Safrany, E., Csongei, V., Jaromi, L., Horvatovich, K., Sipeky, C., Maasz, A., Radics, J., Gyetvai, A., Szekanecz, Z., Czirjak, L., Melegh, B.

Megjegyzések:	Recently, an association was found between Crohn's disease and the interleukin-23 receptor (IL-23R) gene. Since the IL-23/IL-17 pathway is known to associate with other autoimmune diseases, including rheumatoid arthritis (RA) and systemic sclerosis (SSc), we hypothesised that IL-23R could be a shared susceptibility gene. METHODS: Groups of patients with rheumatoid arthritis (n = 412), systemic sclerosis (n = 224), Crohn's disease (n = 190) and healthy controls (n = 220) were genotyped for rs10889677 (exon-3'UTR C2370A), rs2201841, and rs1884444 variants; the first two have been shown to confer risk for Crohn's disease. RESULTS: We observed an increased prevalence of the homozygous rs10889677 AA and homozygous rs2201841 CC genotypes both in the Crohn's disease and in the RA groups as compared to the controls (12.1%, 11.9% vs 5.91%, p<0.05; and 13.2%, 13.1% vs 5.91%, p<0.05), but not in the SSc patients. Logistic regression analysis revealed that bearing these alleles represent risk for the development of rheumatoid arthritis (chi(2) = 5.58, p = 0.018, OR = 2.15, 95% CI 1.14-4.06 for rs10889677; and chi(2) = 7.45, p = 0.006, OR = 2.40, 95% CI 1.28-4.51 for rs2201841). The rs1884444 allele, which has been previously reported as neutral for development of Crohn's disease, was also found neutral for all studied groups in the present study. CONCLUSIONS: The data reported here provide direct evidence that some allelic variants or haplogroups of IL-23R represent independent risk factors for rheumatoid arthritis as well as Crohn's disease, but not for scleroderma.
