OBJECTIVES Ankylosing spondylitis is strongly associated with HLA-B27. However, the strength of the association with HLA-B27 and the clinical features may vary in different parts of the world. The aim of this study is to compare the clinical features of AS and the frequencies of HLA-B27 and its alleles in patients from Turkey with other series. METHODS(More)
Chronic myeloid leukemia (CML) occurs from childhood to old age. The adult form is characterized by the presence of Philadelphia chromosome resulting from bcr/abl translocation. The BCR-ABL fusion proteins are immunogenic, and the junctional sequences show unique HLA class I and class II restriction patterns in vitro. A previous study in the west of(More)
The central Asian country Mongolia is home to more than 20 tribes and ethnic groups, some of which are related to neighboring Turkic populations. The main Mongolian people, Khalkha, live in central and eastern Mongolia while the Tsaatan minority lives in the north of the country. The Oold minority is from the western Altai mountain region and live in close(More)
Exposure to human leukocyte antigens (HLA) via blood transfusions, pregnancies, and previous transplantations can result in anti-HLA antibody production. The presence of anti-HLA antibodies in recipient sera before transplantation is an important risk factor. To demonstrate the anti-HLA antibody status of Turkish end-stage renal disease (ESRD) patients, 674(More)
This study has been designed to investigate the immunogenetic susceptibility of Cyclosporine-A (CsA) immunosuppressed renal transplant patients to development of gingival overgrowth, and the amplifying effect of calcium channel blockers on the severity of this clinical entity. 52 renal transplant recipients were selected and initially grouped as follows:(More)
The frequency and the distribution of HLA-B27 subtypes in spondylarthropathy (SpA) patients and controls were investigated in a sample Turkish population. B27 subtyping was performed by PCR-SSP method in two groups: 49 unrelated HLA-B27 positive Turkish patients with the diagnosis of SpA according to the European Spondyloarthropathy Study Group Criteria,(More)
BACKGROUND Certain cytokine gene polymorphisms (CGPs) have been shown to be associated with renal transplant rejection episodes or graft outcomes. We sought to evaluate the relationships between gene polymorphisms and acute rejection episodes (RG, n = 19) versus stable graft function (NRG, n = 71) in transplant recipients compared with healthy control(More)
HLA-A, B, C and DR antigen frequencies were determined in a group of patients with juvenile periodontitis and rapidly progressive periodontitis. In juvenile periodontitis patients, HLA-A24 and DR4 were found at a significantly higher level than in the control group, and in rapidly progressive periodontitis patients, A9 and DR4 were found at a significantly(More)
AIM Anti-donor antibodies, denoted as "panel-reactive antibodies" (PRAs), are one of the most important factors influencing graft survival after renal transplantation. PRA is generally analyzed with enzyme-linked immunosorbent assay or flow cytometry (FC), which identify the HLA antigen specific for the preformed antibody. PATIENTS AND METHODS We tested(More)
The number of patients with end stage renal disease (ESRD) is increasing faster than the number of renal transplantations performed per year worldwide. Of the primary diseases leading to ESRD, diabetic nephropathy is the leading cause. The purpose of the present study is to investigate the association of HLA with the primary diseases leading to ESRD in(More)
