The aim of this study was to determine the human leukocyte antigen (HLA)-DRB1 alleles in two groups of patients in Latvia: patients with Lyme borreliosis and patients with Lyme neuroborreliosis. The study included 216 patients with Lyme borreliosis, 29 patients with Lyme neuroborreliosis and 282 control persons. All surveyed persons were residents of Latvia. The HLA-DR genotyping was performed ...

We investigated the association of HLA class II alleles and haplotypes with sickle cell anemia vaso-occlusive crisis (VOC). DRB1*100101 was positively associated, while DRB1*140101, DRB1*150101, and DQB1*060101 were negatively associated, with VOC. Both susceptible (DRB1*100101-DQB1*050101) and protective (DRB1*110101-DQB1*030101 and DRB1*150101-DQB1*060101) haplotypes were identified, indicati...

The major histocompatibility complex is directly involved in the immune response, and thus genes coding for its proteins are useful markers study of genetic diversity, susceptibility to disease (autoimmunity infections), transplant medicine, pharmacogenetics, among others. polymorphism system also allows researchers use it as a proxy population genetics analysis, such admixture structure. In or...

OBJECTIVE To provide a table indicating the risk for developing anti citrullinated protein antibody (ACPA) positive rheumatoid arthritis (RA) according to one's HLA-DRB1 genotype. METHODS We HLA-DRB1 genotyped 857 patients with ACPA positive RA and 2178 controls from South Eastern and Eastern France and calculated Odds Ratios (OR) for developing RA for 106 of 132 possible genotypes accounting...

Introduction Systemic Lupus Erythematosus (SLE) is a complex autoimmune and inflammatory disease. Many studies show HLA alleles can be associated with SLE. The aim of this study was to determine the association of HLA-DRB1 alleles with juvenile- onset in Iranian children. Materials and Methods At a case – control study, 31 children with systemic lupus erythematosus (case group) who referred to ...

BACKGROUND The presence of anti-cyclic citrullinated peptide autoantibody is highly specific for rheumatoid arthritis. Certain HLA-DR4 (HLA-DRB1*04) alleles, also known as the "shared epitope," are associated with increased susceptibility to RA. In addition, these alleles may also have relevance for disease outcome. Anti-CCP antibody positivity has been associated with the presence of HLA-DR4 a...

Context: Hepatitis C Virus (HCV) infection is a major cause of chronic cirrhosis and hepatocellular carcinoma. Approximately 30% infected persons with HCV spontaneously clear the viral infection; but, some remaining patients develop HCV. Studies show that HLA molecules play an important role in outcome by influencing efficiency antiviral immune response to infection. It now known polymorphisms ...

OBJECTIVES HLA-DRB1*03 is strongly associated with anti-Jo-1-positive idiopathic inflammatory myopathies (IIM) and there is now increasing evidence that Jo-1 antigen is preferentially expressed in lung tissue. This study examined whether smoking was associated with the development of anti-Jo-1 antibodies in HLA-DRB1*03-positive IIM. METHODS IIM cases were selected with concurrent information ...
