Many clinical human leukocyte antigen (HLA) laboratories are adopting next-generation sequencing (NGS) technology for HLA genotyping. There have been several reports of the cost-benefit and reduction in turn-around-time provided by NGS. Ninety-six percent of buccal swabs and peripheral blood samples had reportable HLA genotyping by NGS. The HLA loci most likely to fail genotyping from buccal swabs were DQB1, DPB1, and DPA1. Successful buccal swab samples had significantly less genomic DNA fragmentation compared to buccal swab samples that were unsuccessful...

To improve assistance for patients awaiting a bone marrow transplant from an unrelated donor, it is important to genetically characterize the Brazilian volunteer bone marrow donors registry (REDOME). Our objective was to describe the antigenic groups and haplotype frequencies of HLA-A, HLA-B and HLA-DRB1 in the five regions of Brazil and by self-reported ethnicity groups using the REDOME data. Our study included 3,038,286 individuals. HLA antigenic groups and haplotype frequencies were estimated using an Expectation-Maximization (EM) algorithm...

BACKGROUND: Psoriasis is a chronic inflammatory disease of the skin. Vascular endothelial growth factor (VEGF), a pro-angiogenic factor, is involved in the pathogenesis of psoriasis. Being highly polymorphic, several SNPs of VEGF have been reported to be associated with increased risk of psoriasis. OBJECTIVES: We determined the association of VEGF gene polymorphisms with risk of psoriasis in South Indian Tamils. METHODS: 300 cases of psoriasis and 300 controls were recruited in this case-control study...

Outbreaks of the Zika, dengue, and chikungunya viruses, especially in the Americas, pose a global threat due to their rapid spread and difficulty controlling the vector. Extreme phenotypes are often observed, from asymptomatic to severe clinical manifestations, which are well-studied in dengue. Host variations are also important contributors to disease outcomes, and many case-control studies have associated single nucleotide polymorphisms (SNPs) with severe dengue. Here, we found that the TC genotype and T-carriers for SNP rs1285933 in the C-type lectin superfamily member 5 (CLEC5A) gene was associated with severe dengue in a Northern Brazilian population (OR=2...

Killer immunoglobulin-like receptors (KIR) are transmembrane proteins that regulate NK and T cell subsets by recognizing HLA-I molecules as ligands. The KIR gene family consists of 16 genes, located at chromosome 19q13.4. KIR gene frequencies vary among populations. In Mexico, HLA and genetic ancestry studies show that Mestizo populations have different genetic backgrounds based on admixture with European, African, and Asian ancestry. This study aimed to evaluate the frequencies of KIR genes and genotypes in Guerrero and Jalisco, two Mexican Mestizo populations located in the south and the west of the country, respectively, and to compare these frequencies with those of other populations...

The detrimental impact of preformed anti-HLA donor-specific antibodies (DSA) is well defined, contrarily to non-donor-specific antibodies (NDSA). We sought to evaluate their clinical impact in a cohort of 724 kidney graft recipients in whom anti-HLA antibodies were thoroughly screened and identified in pre-transplant sera by solid-phase assays. NDSA or DSA were detected in 100 (13.8%) and 47 (6.5%) recipients respectively, while 577 (79.7%) were non-allosensitized (NaS). Incidence of antibody-mediated rejection at 1-year was 0...

BACKGROUND: A simplified protocol for HLA-typing -by NGS, developed for use with the Illumina MiSeq, was performed by technologists with varying NGS experience to assess accuracy and reproducibility. METHODS: Technologists from six laboratories typed the same 16 samples at HLA-A, B, C, DRB1, and DQB1. The protocol includes long range PCR, library preparation, and paired-end 250bp sequencing. Two indexing strategies were employed: locus-specific indexing whereby each locus was tagged uniquely and sample-specific indexing whereby all 5 loci for a sample were pooled prior to library preparation...

The Peer Approaches to Lupus Self-Management program sought to address the disparate impact of systemic lupus erythematosus (SLE) on African American women through a peer mentoring intervention with aims of reducing stress, anxiety, and depression. Given the association between psychological health and immune function this study examines the relationship between patient reported outcomes (PROs) in these domains and immunologic indicators of disease activity. Twenty-three African American women with SLE served as mentees in the intervention from whom PRO measures were collected at the outset, midpoint, and end of the 12 week pilot study...

IL-22 provides a new insight into the mechanisms of autoimmunity, and copy number variations (CNVs) are associated with autoimmune diseases. This study aims to explore the association of IL-22 gene CNVs with ankylosing spondylitis (AS) susceptibility. The copy numbers of IL-22 gene (2 fragments: IL-22_1, IL-22_2) were examined by AccuCopy™ methods in a cohort of 649 AS patients and 628 controls. Association of IL-22 CNVs and AS susceptibility was analyzed, and AS risk was estimated by Odds Ratio (ORs) and 95% confidence intervals (CIs), and the Benjamini-Hochberg method was applied to regulate the false discovery rate (FDR)...

The human platelet antigen (HPA)-1, -2, -3, -5, and -15 systems are characterized as polymorphic alloantigens expressed on platelets and endothelial cells. In this retrospective study, we investigated, whether HPA-1, -2, -3, -5, and -15 incompatibilities are associated with acute cellular liver transplant rejection. A total of 96 Caucasian liver transplant recipients and corresponding donors were analyzed, 43 with biopsy proven acute cellular rejection (BPAR) and 53 without acute cellular rejection (No-BPAR)...

Accumulated evidence indicates that polymorphisms in human leukocyte antigens (HLA) are associated with susceptibility to coronary artery disease (CAD). However, whether HLA-DQB1 alleles are correlated with susceptibility to CAD is unclear. In this study, significantly lower frequencies of the allele groups (DQB1*03:01:01G and DQB1*05:03:01G) and the genotypes (DQB1*03:01:01G/DQB1*03:01:01G and DQB1*03:01:01G/DQB1*05:03:01G) were observed in the CAD group compared with that in the controls. However, notably higher frequencies of DQB1*04:01:01G and genotype DQB1*05:01:01G/DQB1*03:01:01G were observed in the CAD patients than in the controls...

The posttransplant development of donor specific antibodies (DSA) initiates the antibody mediated rejection (AMR), which is associated with the increased rate of graft loss. One of the characteristics of AMR is the infiltration of innate immune system including macrophages, monocytes, neutrophils or NK cells. Macrophage inhibitory factor (MIF) and B-cell activating factor (BAFF) are well known cytokines that are associated with the activation of the innate immune system which can damage kidney allograft. In this article, the association of the genetic polymorphisms of MIF and BAFF with the development of DSA including Class I and II in kidney transplant patients is investigated...

BACKGROUND: Presence of antibody[Ab] against angiotensin receptor[AT1R] indicates heightened risk for antibody mediated rejection[AMR] after transplantation but is insufficient as a marker. We speculated AT1R might be released systemically because of AMR and might be a useful biomarker. METHODS: AT1R was measured in blood from 73 Normals and 72 renal patients pre- and post-transplantation. Patients were stratified as AMR-free[Gp1], AMR<1yr[Gp2] and AMR>1yr[Gp3]...

Alarm antiproteases, i.e. secretory leukocyte protease inhibitor ad elafin, are key mediators in innate immune response and integrate innate and adaptive immunity systems. The aim of the study was to assess clinical significance of serum levels of alarm antiproteases, elafin and secretory leukocyte protease inhibitor (SLPI) in patients with systemic sclerosis (SSc). Twenty-eight patients with SSc, 25 patients with rheumatoid arthritis (RA) and 22 healthy controls were recruited. Serum elafin and SLPI levels were examined using enzyme-linked immunosorbent assay (ELISA)...

REVIEW
Harold C Sullivan, Howard M Gebel, Robert A Bray
As the practice of medicine becomes more reliant on imaging and laboratory tests, medical decisions will be increasingly based on numbers. Accordingly, following the introduction of solid-phase testing to the HLA testing repertoire, laboratory directors and physicians have employed preset mean fluorescence intensity (MFI) thresholds as the basis for decisions in the management of transplant patients. However, what do MFI values mean? The literature is rife with reports detailing numerous factors that influence antibody assessment including (but not limited to) sensitization history of the patient, level of mismatch between donor and recipient, presence of interfering substances in the serum, whether the antigen on multiplex beads is native or denatured, day-to-day and technologist variability, and the historical performance of an assay in a given institution...

Killer-cell Immunoglobulin-like Receptor (KIR) and Human Leukocyte Antigen (HLA) genotypes vary considerably between individuals and populations due to KIR/HLA allelic variation and variable haplotype configurations of KIR. HLA mediate natural killer cell activity by serving as KIR ligands. KIR/HLA polymorphisms associate with both disease susceptibility and severity. We determined the frequencies of KIR, KIR genotypes and KIR-HLA combinations in 364 healthy individuals from four South African populations. Study participants included black African (n=167), Caucasian (n=97), Mixed ancestry (n=50) and Indian (n=50) individuals...

Rheumatoid arthritis (RA) is a common autoimmune disease with a complex genetic background. The peptidyl arginine deiminase type IV (PADI4) gene has been associated with RA susceptibility in several populations. We addressed the relationship between three exonic PADI4 gene single nucleotide polymorphisms (SNPs) PADI4_89 (rs11203366), PADI4_90 (rs11203367) and PADI4_92 (rs874881) and related haplotypes with RA in a population from Southern México. This study included 200 RA patients and 200 control subjects...
