The spectrum of association in HLA region with rheumatoid arthritis in a diverse Asian population: evidence from the MyEIRA case-control study.

Background: Fine-mapping of human leukocyte antigen (HLA) region for rheumatoid arthritis (RA) risk factors has identified several HLA alleles and its corresponding amino acid residues as independent signals (i.e., HLA-A, HLA-B, HLA-DPB1, and HLA-DQA1 genes), in addition to the well-established genetic factor in HLA-DRB1 gene.

HLA-A, -B, -C, -DRB1 and -DQB1 alleles and haplotypes in 271 Southeast Asia Indians from Peninsular Malaysia.

A total of 271 Southeast Asia Indians from Peninsular Malaysia were genotyped for HLA-A, -B, -C, -DRB1, and -DQB1 loci using polymerase chain reaction sequence-specific oligonucleotide probe hybridization methods. In this report, HLA-B and HLA-DQB1 was in Hardy-Weinberg proportions (HWEP) (p > 0.05).

Diagnostic performance of anti-RA33 antibody as a serological marker for rheumatoid arthritis.

Introduction: Rheumatoid arthritis is diagnosed based on the 2010 Rheumatoid Arthritis Classification Criteria whereby rheumatoid factor and anti-citrullinated protein antibody are the serological markers included in these criteria. Anti-RA33 antibody has the potential to provide additional diagnostic value in rheumatoid arthritis. The aim of this study is to determine the diagnostic performance of anti-RA33 antibody as a serological marker for rheumatoid arthritis.

HLA-A, -B, -C, -DRB1 and -DQB1 alleles and haplotypes in 194 Southeast Asia Chinese from Peninsular Malaysia.

A total of 194 Southeast Asia Chinese from Peninsular Malaysia were genotyped for HLA-A, -B, -C -DRB1, and -DQB1 loci using polymerase chain reaction sequence-specific oligonucleotide probe hybridization methods. In this report, the HLA-B, HLA-DRB1 and HLA-DQB1 were in Hardy-Weinberg proportions (HWEP) (p > 0.05).

The association between serum prolactin levels and interleukin-6 and systemic lupus erythematosus activity.

Based on the recent evidence of association between hyperprolactinemia and systemic lupus erythematosus disease activity (SLEDAI), a study was conducted to analyze the association of hyperprolactinemia with lupus nephritis disease activity. In this cross-sectional study, the analysis was conducted on SLE patients who visited the University Kebangsaan Malaysia Medical Centre (UKMMC) Nephrology Clinic from August 2015 till February 2016. The disease activity was measured using the SLEDAI score, with more than 4 indicating active lupus nephritis.

HLA-A, -B, -C, -DRB1 and -DQB1 alleles and haplotypes in 951 Southeast Asia Malays from Peninsular Malaysia.

A total of 951 Southeast Asia Malays from Peninsular Malaysia were genotyped for HLA-A, -B, -C -DRB1, and -DQB1 loci using polymerase chain reaction sequence-specific oligonucleotide probe hybridization methods. In this report, there were significant deviation from Hardy-Weinberg proportions for the HLA-A (p<0.0001), -B (p<0.

Beyond the joints in rheumatoid arthritis: Effects of adalimumab on hematologic and lipid indices.

Tumor necrosis factor alpha (TNFα) is a multifunctional cytokine which plays a pivotal role in the pathogenesis of rheumatoid arthritis (RA). Apart from its well recognized proinflammatory properties, it is known to interfere with lipid metabolism and erythropoiesis. We evaluated the effects of adalimumab on hematologic, lipid and inflammatory parameters using data from patients on adalimumab 40 mg fortnightly from 2 centers in Malaysia.

Implications of immunosuppressive agents in cardiovascular risks and carotid intima media thickness among lupus nephritis patients.

Introduction: Patients with systemic lupus erythematosus, particularly with lupus nephritis (LN), are at risk of premature cardiovascular (CV) disease.

Objective: To determine the association between immunosuppressive medications, traditional CV risk factors and carotid intima media thickness (CIMT) among patients with LN.

Methodology: This was a cross-sectional study in which consecutive LN patients attending the Nephrology/SLE Clinic were evaluated for traditional CV risk factors.

Thickened carotid intima media thickness and carotid atherosclerosis among lupus nephritis patients: the role of traditional and lupus-specific factors.

Aim: The objectives of this study were to investigate the frequency of thickened carotid intima media thickness (CIMT) and atherosclerosis among lupus nephritis (LN) patients and to study their associated risk factors.

Method: In this cross-sectional study, carotid ultrasonography was performed on consecutive LN patients to determine CIMT and presence of carotid plaques. CIMT was considered to be abnormally thickened if it was more than the 75th percentile matched for age and sex from the 'Carotid Atherosclerosis Progression Study'.

A cross-sectional study of diastolic dysfunction in rheumatoid arthritis and its association with disease activity.

Aims: The aim of this study was to evaluate the left ventricular (LV) diastolic dysfunction in rheumatoid arthritis (RA) patients without clinically evident cardiovascular manifestations and to estimate whether there is any correlation between RA disease severity and disability and LV diastolic dysfunction.

Methods: The study was a cross-sectional study involving 53 patients (47 female and 6 male) with RA without clinically evident heart disease and 53 healthy subjects (47 female and 6 male) who served as a control group. Both groups were matched for age and sex.

Clinical and high resolution computed tomography characteristics of patients with rheumatoid arthritis lung disease.

Introduction: Rheumatoid arthritis (RA) is a systemic disease of unknown cause. A variety of pulmonary disorders have been described in association with RA. Among the most common are interstitial lung disease (ILD) and bronchiectasis.

Extragonadal germ cell tumor presenting in a woman with systemic lupus erythematosus: a case report.

Introduction: Germ cell tumor of the pituitary gland is a very rare occurrence.

Case Presentation: We describe the case of a 28-year-old Malaysian Malay woman with lupus nephritis who complained of a three month headache and blurring of vision. She was found to have a pituitary mass, which was later proven to be a germ cell tumor.
