Structural human leukocyte antigen (HLA) matching at the eplet level can be identified by HLAMatchmaker, which requires the entry of four-digit alleles. The aim of this study was to evaluate the agreement between eplet mismatches calculated by serological and two-digit typing methods compared to high-resolution four-digit typing. In a cohort of 264 donor/recipient pairs, the evaluation of measu...
background: thalassemia is probably the most common single gene disorder causing a major public health problem in the world. currently, allogenic hematopoietic stem cell transplantation (hsct) is the only curative therapy for thalassemia. one major limitation of hsct is the lack of hla-identical sibling donors, so attention has turned to finding phenotypically matched unrelated donors. patients...
OBJECTIVES To study the correlation between the HLA-B*5701 allele and the single nucleotide polymorphism in HCP5 (rs2395029). PATIENTS AND METHODS All HIV patients naive for abacavir seen at our institution between September 2007 and December 2008 were prospectively screened for HLA-B*5701. HCP5 rs2395029 genotyping was carried out by allelic discrimination using the TaqMan 5'-nuclease assay....
Human leukocyte antigens (HLA) are important biomarkers because multiple diseases, drug toxicity, and vaccine responses reveal strong HLA associations. Current clinical HLA typing is an elimination process requiring serial testing. We present an alternative in situ synthesized DNA-based microarray method that contains hundreds of thousands of probes representing a complete overlapping set cover...
Epitope-based HLA matching has been emerged over the last few years as an improved method for HLA matching in solid organ transplantation. The epitope-based matching concept has been incorporated in both the PIRCHE-II and the HLAMatchmaker algorithm to find the most suitable donor for a recipient. For these algorithms, high-resolution HLA genotype data of both donor and recipient is required. S...
ABSTRACT: Our primary goal in this study was to find if there is a meaningful correlation between HLA system and congenital UPJO and whether it is possible to use HLA system as a diagnosis marker in congenital UPJO. In this study, 30 patients whose congenital UPJO were confirmed by imaging, underwent HLA typing . The number of the control group who were all kidney donors was two times more th...
previous studies have demonstrated some significant differences in hla allele frequencies in leukemic patients and normal subjects. we have analyzed hla class ii alleles and haplotypes in 60 iranian patients with acute myelogenous leukemia (aml) and 180 unrelated normal subjects. blood samples were collected after obtaining informed consents. from the patients and control dna extraction and hla...
Despite recent advances in DNA-based genotyping, the microcytotoxicity test is still broadly used for the determination of human leukocyte class I antigens in patients as well as organ donors and also for the detection of HLA antibodies. Excellent purity and viability of peripheral blood mononuclear cells (PBMC) are essential for reliable HLA typing results. Background staining and cell loss ca...
OBJECTIVE To devise a new and simple technique to help select normal embryos that are human leukocyte antigen (HLA) matched to their affected siblings for diseases, such as beta-thalassemia or sickle cell anemia, which are common in this part of the world. METHODS This study was conducted between March 2008 and April 2011 at the preimplantation Genetic Diagnosis Laboratory, Saad Specialist Ho...
As compared with related HLA-identical sibling donors, bone marrow transplantation (BMT) with phenotypically HLA ABDR-compatible unrelated donors is associated with increased mortality. This may be due to hidden HLA incompatibilities not detected by conventional typing. We have analyzed 44 unrelated patient-donor pairs who were matched for HLA-A, -B, and -DR by routine tissue typing. Our compre...
