From a historical and genetic point of view, the Otomi of the Mezquital Valley are a frontier people that have played an important role in the population dynamics of the Mexican Central Plateau. Due to the antiquity of their presence in the area, the Otomi may be bearers of ancient genetic variability, shared mainly today with other groups belonging to the Otomanguean linguistic family and with...
Objective: This study aimed to investigate the association between HLA alleles and visceral leishmaniasis (VL) in a sample of Iraqi patients. Methods: A total of 30 patients were studied, in addition to 20 age, gender and ethnicity matched controls. All subjects were genotyped by polymerase chain reaction-sequence specific primers (PCR-SSP) method. Results: For HLA-class I region (A and B loci)...
Hepatitis C virus (HCV) infection is a global medical problem. The current standard of treatment consists of the combination of peginterferon plus ribavirin. This regimen eradicates HCV in 55% of cases. The immune response to HCV is an important determinant of disease evolution and can be influenced by various host factors. HLA class II may play an important role in immune response against HCV....
Association of the major histocompatibility complex (MHC) class II-encoded HLA-DRB1-DQA1-DQB1 haplotype with Graves' disease (GD) has been known for several years. Recent evidence from other autoimmune diseases has suggested that the HLA class I encoded HLA-B/-C molecules could be conferring HLA-DRB1-DQA1-DQB1 independent effects on disease. The aim of this study was to determine the effect of ...
INTRODUCTION Rheumatoid arthritis is an autoimmune disease with poorly understood pathophysiology. Genetic components of disease etiology, especially human leukocyte antigen (HLA) associations, are well known. Ethnic differences account for a number of variations in disease association with the HLA locus and there seem to be differences in various studies regarding its genetic predisposition. T...
An association of several HLA alleles with myasthenia gravis (MG) has been reported. Aim of this work was to analyze the HLA allele profile in a survey of 76 unselected Italian MG patients and in a subgroup characterized by disease onset after the age of 50 years, absence of thymoma, and presence of antiacetylcholine receptor antibodies. We defined this subgroup by the acronym LOAb. Typing was ...
Occupational asthma caused by western red cedar is a common problem in sawmill industries. The objective of this study was to examine a possible association of human leukocyte antigen (HLA) class II genetic markers with susceptibility or resistance to western red cedar induced asthma. The distribution of DRB1 and DQB1 HLA class II alleles and DRB1-DQB1 haplotypes was studied in 56 Caucasian pat...
Genetic susceptibility to insulin-dependent diabetes mellitus (IDDM) is associated with the HLA-DR3 and DR4 haplotypes. The HLA-DR2 haplotype is negatively associated with IDDM, an association that has been interpreted as dominant protection. Here, we describe the molecular analysis of the HLA class II genes in an unusual family with three HLA-DR1/2 siblings, all of whom have IDDM. With polymer...
BACKGROUND The objective of this study was to investigate HLA-DRB1*and DQB1* allelic polymorphisms in Iranian patients with hydatidose. This is the first survey dealing with the correlation between HLA-DRB1* and DQB1* alleles and cystic echinococcosis in Iranian patients. METHODS The study was carried out on 56 patients with confirmed cystic echinococcosis and 30 apparently healthy individual...
Human papillomavirus (HPV) infection is a major risk factor for cervical cancer. However, only some high risk human papillomavirus (HR-HPV)-infected women progress to cervical cancer, host immunogenetic factors human leukocyte antigen (HLA) may account for viral antigens presenting individually or together in the progression to cervical cancer. This study examined the association between the de...
