Although a number of studies have reported that human leukocyte antigen (HLA)-DRB1 alleles may be correlated with tuberculosis (TB), most were based on small samples or inconsistent and unclear results. Here, we present a meta-analysis to investigate the relationship between HLA-DRB1 alleles and TB susceptibility. We gathered relevant information from published studies on the association betwee...

To investigate why human leukocyte-associated antigen-DRB1*0301 (HLA-DRB1*0301) positive Scandinavian patients have a better prognosis than HLA-DRB1*0301 negative patients, the present authors examined patterns of cytokine expression in bronchoalveolar lavage (BAL) cells and BAL fluid (BALF) from patients with pulmonary sarcoidosis and controls. Using real-time PCR, the mRNA expression of selec...

Multiple Sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system. It is a clinically heterogeneous disorder especially in terms of disease severity. Current investigations suggest that genes and gene-gene interactions not only influence on susceptibility to MS but also affect the disease severity. In this study, we investigated the contribution of the HLADRB1*1501 ...

OBJECTIVE This study aimed to investigate the association between HLA class II alleles and the occurrence of FVIIIinhibitor in Thai hemophilia A patients. MATERIAL AND METHODS The distribution of HLA-DRB1 alleles and DQB1 alleles in 57 Thai hemophilia A patientsand 36 blood donors as controls was determined using the PCR sequence-specific primer (PCR-SSP) method, and theassociation between th...

Background: Cholecystitis is one of the major digestive diseases. Its prevalence is particularly high in some populations. Significant risk factors associated with cholecystitis include age, sex, obesity, diet, parity and type 2 diabetes. Objective: To determine the association between HLA-DRB1 and cholecystitis. Methods: This casecontrol study included forty Iraqi Arab patients who had cholecy...

Genetic control of immune reactions has a major role in the development of rheumatic heart disease (RHD) and differs between patients with rheumatic fever (RF). Some authors think the risk of acquiring RHD is associated with the HLA class II DR and DQ loci, but other views exist, due to the various HLA-typing methods and ways of grouping cases. Our goal was to determine the relations between HL...

The aim of this study was to analyze the relationship between polymorphism of the MHC-DRB1/DQB1 gene and its resistance to Cystic Echinococcosis (C.E), as well as to screen out the molecular genetic marker of antiechinococcosis in Chinese Merino sheep. The MHCII-DRB1/DQB1 exon 2 was amplified by polymerase chain reaction (PCR) from DNA samples of healthy and hydatidosis sheep. PCR products were...

BACKGROUND A strong genetic influence by the MHC class II region has been reported in sarcoidosis, however in many studies with different results. This may possibly be caused by actual differences between distinct ethnic groups, too small sample sizes, or because of lack of accurate clinical subgrouping. SUBJECTS AND METHODS In this study we HLA typed a large patient population (n = 754) recr...

BACKGROUND We evaluated the significance of the genes, defined as DRB1*04 or DRB1*01, in rheumatoid arthritis (RA) patients. We focused on the role of genetic and serologic markers to predict disease activity and destructive process of joints. METHODS Sixty patients with RA were examined. Radiographic changes were evaluated by (Larsen score) and disease activity was measured by disease activi...

Objective. To re-evaluate the roles of HLA-DRB1 alleles in susceptibility to SLE and RA and their effects on autoantibody status in large-scale Japanese cohorts. Methods. A total of 656 SLE, 2410 RA and 911 control subjects, who were all Japanese, were genotyped for HLA-DRB1 alleles using sequence-specific oligonucleotide probes. The association of alleles with disease susceptibility was tested...
