Megjegyzések:Objectives: HLA-DRB1*03 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-DRB1*03-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-DRB1*03 and anti-Jo-1status was observed across all four cohorts (DRB1*03frequency: 74% Jo-1-positive vs 35% Jo-1-negative, OR5.55, 95% CI 3.42 to 9.14, p<0.0001). The frequency ofHLA-DRB1*03 was increased in smokers. The frequencyof anti-Jo-1 was increased in DRB1*03-positive smokersvs DRB1*03-negative non-smokers (42% vs 8%, OR 7.75,95% CI 4.21 to 14.28, p<0.0001) and DRB1*03-positivenon-smokers (42% vs 31%, p=0.08). In DRB1*03-negative patients, anti-Jo-1 status between smokers andnon-smokers was not signifi cantly different. No signifi cantinteraction was noted between smoking and DRB1*03status using anti-Jo-1 as the outcome measure.Conclusion Smoking appears to be associated withan increased risk of possession of anti-Jo-1 in HLADRB1*03-positive IIM cases. The authors hypothesisethat an interaction between HLA-DRB1*03 and smokingmay prime the development of anti-Jo-1 antibodies.

Cím:Association of rheumatoid arthritis with HLA-DR1 and HLA-DR4 in Hungary / Kapitany, A., Zilahi, E., Szanto, S., Szucs, G., Szabo, Z., Vegvari, A., Rass, P., Sipka, S., Szegedi, G., Szekanecz, Z.

Megjegyzések:Susceptibility to and outcome for rheumatoid arthritis (RA) have been associated with particular HLA-DR alleles, but these alleles vary among ethnic groups and geographic areas. The frequency of HLA-DR1 (HLA-DRB1*0101, DRB1*0102) and HLA-DR4 (DRB1*0401, DRB1*0404) alleles is elevated among Caucasian patients with RA. We studied a northeastern Hungarian population of RA patients to determine the frequency of HLA-DR1 and HLA-DR4 phenotypes in this population and to compare it with healthy control subjects, as well as to investigate whether the presence of these alleles could be a marker for RA. We performed HLA-DRB1 genotyping (DRB1*01-DRB1*16) in 83 RA patients and 55 healthy controls using polymerase chain reaction with sequence-specific primers (PCR-SSP). In the case of HLA-DR1- or HLA-DR4-positive patients, the DR1 and DR4 subtypes were also determined. The frequency of HLA-DR4 alleles was significantly higher in RA patients than in controls (31.3 vs. 10.9%; P <.05). HLA-DR1, in particular, tended to be more frequent in patients than in controls (32.5 vs. 18.1%). Among the HLA-DR4 subtypes, DRB1*0401 and DRB1*0404 were the most common alleles found in both groups. However, no significant differences were seen in the frequency of HLA-DRB1*0401 and HLA-DRB1*0404 between RA patients and controls. In contrast, HLA-DRB1*0405 and HLA-DRB1*0408 were significantly more common in RA patients than in control subjects. Among HLA-DR1 subtypes, the DRB1*0101 allele was most commonly detected, but HLA-DRB1*0101 as well as DRB1*0102 and DRB1*0105 were similarly frequent in RA patients and controls. HLA-DR12 was more common among controls than in RA patients (18.1 vs. 0%; P <.05). Our results generally agree with the findings in other Caucasian populations. Nonetheless, we found differences in the frequency of HLA-DR1 and HLA-DR4 subtypes among Hungarian patients compared with reports from other geographic regions (e.g., Finland and Asia). Our data suggest that in northeastern Hungary, HLA-DR4 as well as its subtypes DRB1*0405 and DRB1*0408 may be involved in susceptibility to RA, but HLA-DR1 may not. In addition, the presence of HLA-DR12, at least in Hungary, may protect from this disease.

Cím:Primary lung adenocarcinoma associated with anti-Jo-1 positive polymyositis / Melinda Vincze, Peter A. Molnár, Erika Zilahi, Anikó Kapitány, Balázs Dezső, István Takács, Katalin Dankó
Dátum:2011
ISSN:1778-7254
Megjegyzések:We present a female with anti-Jo-1 positive polymyositis and lung adenocarcinoma. Her polymyositis diagnosis was based on her clinical symptoms, electromyography results, and highly elevated muscle enzymes, including creatine kinase and lactate-dehydrogenase. Anti-Jo-1 positivity, leukocytosis and elevated tumor markers: CA 15-3 and CA 72-4 were also certified at the diagnosis. Her malignancy was finally diagnosed by transthoracic needle biopsy, two years after the appearance of first symptoms of polymyositis. After surgical removal of the tumor, polymyositis was in remission. Due to the symptoms mentioned above and the coincidence of the tumor, a paraneoplastic myositis was suspected.

Cím:Systemic sclerosis-rheumatoid arthritis overlap syndrome : a unique combination of features suggests a distinct genetic, serological and clinical entity / Szucs, G., Szekanecz, Z., Zilahi, E., Kapitany, A., Barath, S., Szamosi, S., Vegvari, A., Szabo, Z., Szanto, S., Czirjak, L., Kiss, C.

Megjegyzések:To determine the genetic, clinical and serological characteristics of systemic sclerosis (SSc)-rheumatoid arthritis (RA) overlap syndrome. METHODS: Clinical manifestations and immunolaboratory features of 22 SSc-RA patients were assessed. The HLA-DR genotype of the 22 SSc-RA patients determined by SSP-PCR was compared with that of 38 SSc patients, 100 RA patients and 50 healthy controls. RESULTS: All overlap patients fulfilled the American College of Rheumatology (ACR) criteria for SSc and RA. Five of the 22 patients (23%) had diffuse cutaneous SSc (dcSSc) and 17 patients (77%) had limited cutaneous SSc (lcSSc). Antinuclear antibody, anti-Scl70, IgM rheumatoid factor and anti-CCP antibody positivity were detected in 22 (100%), 5 (23%), 16 (73%) and 18 patients (82%), respectively. Seventeen patients (77%) had pulmonary fibrosis, 12 (55%) had oesophageal dismotility, 11 (50%) had cardiac and five (23%) had renal involvement. Hand joint destruction was observed in 18 patients (82%). Significantly increased frequencies of HLA-DR3 (36% vs 5%), HLA-DR7 (9% vs 4%), HLA-DR11 (36% vs 7%) and HLA-DRw53 (23% vs 5%) were observed in SSc-RA compared with RA patients (P < 0.05). Allele frequencies of the 'shared epitope' (HLA-DR1 and -DR4) were significantly increased in SSc-RA (32% and 27%, respectively) and RA patients (46% and 31%, respectively) in comparison with SSc patients (10.5% and 16%, respectively) or healthy controls (16% and 14%, respectively) (P < 0.05). CONCLUSIONS: To date this is the largest SSc-RA overlap cohort. Genetics, clinical and immunolaboratory features suggest a mixed phenotype. Our data suggest that SSc-RA overlap syndrome may be a distinct genetic, immunological and clinical entity.

Cím:HLA-DR genotypes in familial rheumatoid arthritis : increased frequency of protective and neutral alleles in a multicase family / Szilvia Zsilák, János Gál, László Hodinka, Katalin Rajczy, Attila Balog, Sándor Sipka, Sándor Baráth, Anikó Kapitány, Erika Zilahi, Zoltán Szekanecz
Dátum:2005
Megjegyzések:We describe a unique family where each of the 5 siblings in the second generation has rheumatoid arthritis (RA). Two other members of the family have RA and systemic lupus erythematosus (SLE), respectively. No members of previous generations in the family had documented inflammatory arthritis. Due to the suspected genetic predisposition, HLA-DR genotypes were determined in the affected siblings and their parents, children, and grandchildren. We investigated the possible role of various HLA-DR alleles in the evolution of RA in this multicase family. METHODS: HLA-DRB1* alleles were determined by polymerase chain reaction using the sequence-specific primer-Olerup method. RESULTS: The most common alleles in the 6 persons with RA were HLA-DRB1*07 and DRB1*15, which are known to be protective and neutral in RA. No patient or family member carried any HLA-DR4 alleles. CONCLUSION: HLA-DRB1*07 and DRB1*15 alleles are thought to be protective or neutral in RA. However, the majority of RA patients in the family and nearly half of all family members carried these alleles, suggesting a role of these genotypes in susceptibility to RA. No RA patient in this family carried HLA-DR4 alleles. Thus, in our rare family with 6 RA cases, an unexpected genetic background may be involved in the increased susceptibility to inflammatory arthritis.
