HLA-DQA1*04: 01 is related to a higher multiple sclerosis lesion load on T2/Flair MRI sequences

Arq. neuropsiquiatr; 79 (12), 2021
ABSTRACT Background: The genetic predisposition to multiple sclerosis (MS) is associated with HLA alleles, especially HLA-DRB1*15:01. Objective: To identify associations between findings in magnetic resonance imaging (MRI) and genetic features in a Brazilian cohort of patients with MS. Methods: We retros...

Distribution of HLA-DRB1 alleles in BRICS countries with a high tuberculosis burden: a systematic review and meta-analysis

Abstract INTRODUCTION: Tuberculosis (TB) is the leading cause of death worldwide caused by a single infectious disease agent. Brazil, Russia, India, China, and South Africa (BRICS) account for more than half of the world's TB cases. Bacillus Calmette-Guérin (BCG) remains the only vaccine available des...

Polimorfismos do gene HLA-DRB1 em pacientes pediátricos com hepatite autoimune tipo 1 e hepatite autoimune associada à colangite autoimune

Arq. gastroenterol; 56 (2), 2019
ABSTRACT BACKGROUND: Autoimmune hepatitis (AIH) is a rare chronic inflammatory liver disease associated with a loss of immunological tolerance to self-antigens. Susceptibility to AIH is partially determined by the presence of genes related to human leukocyte antigen (HLA), mainly allelic variants of DR...

Human leukocyte antigen HLADRB1 determinants susceptibility to gastroesophageal reflux disease

Arq. gastroenterol; 54 (1), 2017
ABSTRACT BACKGROUND Gastroesophageal reflux disease (GERD) is characterized by diverse symptoms. There is an evidence for a genetic component to GERD as supported by familial aggregation of this disease. OBJECTIVE To investigate whether certain human leucocyte antigen genes HLA-DRB1 are associated with...

Lack of association between alopecia areata and HLA class I and II in a southeastern Brazilian population

An. bras. dermatol; 91 (3), 2016
Abstract: Background: Alopecia areata (AA) is a common disorder of unknown etiology that affects approximately 0.7% to 3.8% of patients among the general population. Currently, genetic and autoimmune factors are emphasized as etiopathogenic. Studies linking Human Leukocyte Antigens (HLA) to AA have sugg...
