Background. Genetic studies of end-stage renal disease (ESRD), including those of human leukocyte antigen (HLA) genes, have been reported in several populations but have not yet been evaluated in Indonesia. Some studies have reported that these genes had a substantial role in ESRD. This study aims to analyze the association between HLA genes and ESRD within the Indonesian community. Method. A retrospective study to investigate HLA class I and II alleles to find out the distribution of HLA-A, -B, -C, -DPB1, -DQB1, and -DRB1 in renal transplant recipients and to ascertain their role in susceptibility to ESRD was performed on totally 149 subjects, consisting of 69 ESRD patients and 80 healthy controls. HLA typing was determined using Luminex techniques. The allele and haplotype frequencies were compared between ESRD patients and controls. Result. High-frequency alleles were HLA-A ∗ 24 (43.6%), B ∗ 15 (38.2%), C ∗ 08 (30.8%), DRB1 ∗ 12 (47.3%), DQB1 ∗ 03 (50.6%), and DPB1 ∗ 13 (22.5%). HLA-A ∗ 24 p = 0.01 and HLA-B ∗ 35 p = 0.02 were associated with a protective effect, with OR 0.537 (95%CI 0.34–0.86) and 0.316 (95%CI 0.11–0.88), respectively. There were some two-locus haplotypes associated with susceptibility to ESRD, such as B ∗ 15-DRB1 ∗ 12, B ∗ 13-DRB1 ∗ 15, A ∗ 02-B ∗ 15, A ∗ 02-C ∗ 08, and B ∗ 13-DQB1 ∗ 05. HLA-A ∗ 02-B ∗ 15-DRB1 ∗ 12 and A ∗ 24-B ∗ 13-DRB1 ∗ 15 appear to be associated with susceptibility to ESRD. Conclusion. The allele groups of HLA-A ∗ 24 and HLA-B ∗ 35 are associated with protection from ESRD. Meanwhile, HLA-B ∗ 13-DRB1 ∗ 15 and A ∗ 24-B ∗ 13-DRB1 ∗ 15 are the most frequent HLAs associated with ESRD in two-locus and three-locus haplotype, respectively.

Systemic Lupus Erythematosus (LES) isan autoimmune inflammatory disease characterized by the formation of antinuclear antibodies (ANA) and anti-double stranded DNA (anti-dsDNA) antibodies as diagnostic markers. Detection of such autoantibodies requires advanced equipment and trained personnel.This study was conducted to acquire candidate antigens that can be used for rapid test kit for practical and accurate detection of ANA and anti-dsDNA to speed up SLE diagnosis.Nuclear proteins and DNA derived from cell lines, hair follicles, and leukocytes of SLE patients and healthy individuals were isolated using QiaGEN kit and modifiedmanual procedure. Antigen-antibody bonds were tested by dot blot assay.The strongest binding between DNA antigens of a healthy individual and antibodies occurred at dilution factors of 1:5,120 for the antigen and 1:2,560 for the antibody. The strongest binding between nuclear protein antigens from the cell line and antibodies occurred at dilution factors of 1:512 for the antigen and 1:1,600 for the antibody.Nuclear antigens derived from cell line and DNA antigens of healthy individuals were antigen candidates for the development of ANA and anti-dsDNA rapid detection tests.
