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:The Impact of Drug Metabolism Gene Polymorphisms on Therapeutic Response and Survival in Diffuse Large B-Cell Lymphoma Patients / Ildikó Pál, Árpád Illés, Lajos Gergely, Tibor Pál, Zita Radnay, Zoltán Szekanecz, Erika Zilahi, László Váróczy
Dátum:2018
ISSN:1565-1088
Megjegyzések:Background: Diffuse large B-cell lymphoma (DLBCL) accountsfor 30% of all non-Hodgkin lymphomas (NHL) and 80% ofagressive lymphomas. Besides the traditional InternationalPrognostic Index (IPI), some other factors may also influencethe prognosis of DLBCL patients.Objectives: To study how the genetic polymorphisms in themetabolic pathway influence the event-free and overall survivalsand therapeutic responses in DLBCL.Methods: The study was comprised of 51 patients (32 men, 19women). The average age was 53.1 years. DLBCL was diagnosedbetween 2011 and 2016 and the average follow-up time was3.78 years. These patients received 1?8 cycles (an average of6.2 cycles) of rituximab, cyclophosphamide, doxorubicin, vincristin,prednisolon (R-CHOP) immunochemotherapy. Real-timepolymerase chain reaction was used to determine the geneticpolymorphisms of CYP2E1, GSTP1, NAT1, and NAT2 genes.Results: Our results showed that the polymorphisms of CYP2E1,GSTP1, and NAT1 genes did not influence the prognosis ofDLBCL patients significantly. In terms of the NAT2 gene, GGhomozygous patients showed slightly better therapeuticresponse and survival results compared to those bearing an Aallele; however, the differences were not statistically significant.Conclusions: Our results could not confirm that genetic polymorphismin metabolic pathways has any predictive role inDLBCL.

Cím:Vitamin D receptor gene polymorphism in rheumatoid arthritis and associated osteoporosis / Rass, P., Pakozdi, A., Lakatos, P., Zilahi, E., Sipka, S., Szegedi, G., Szekanecz, Z.
Dátum:2006
ISSN:0172-8172
Megjegyzések:Rheumatoid arthritis (RA) is commonly associated with decreased bone mineral density (BMD) due to numerous factors. BsmI polymorphism of the vitamin D receptor (VDR) gene has been implicated in the pathogenesis of osteoporosis. Vitamin D has several immunomodulatory effects and thus may play a role in the course of arthritis. However, little data is available on the possible relationship between RA and VDR gene polymorphisms. In this study, the frequency of BsmI polymorphism genotypes were compared with that found in other countries. In this study, 64 RA patients and 40 healthy controls were tested for VDR gene BsmI polymorphism genotypes. Frequencies of B and b alleles were associated with markers of bone metabolism and RA. Among control subjects, the frequency of the BB genotype is relatively high (27.5%). In RA with secondary osteopenia/osteoporosis the BB genotype was more rare, the bb was more common than in control subjects. Markers of bone metabolism were associated with the B allele. RA patients carrying the B allele had lower BMD and increased bone loss over 1 year. The B allele was also correlated with increased osteoclast and osteoblast function, as determined by the assessment of biochemical markers of bone metabolism. Rheumatoid factor titer, which is an independent marker for disease progression in RA, was higher in bb patients. Our data suggest, that the imbalance in B and b allele expression may be involved in the pathogenesis of RA-associated osteoporosis. The possible involvement of vitamin D and VDR gene polymorphisms in the development and progression of RA needs further elucidation.

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.
