INTRODUCTION
Rheumatology and immunology are fields of medicine focused on understanding and treating autoimmune and inflammatory conditions that affect the joints, connective tissues, and immune system.Biotechnological advancements have significantly enhanced our understanding of these diseases and expanded treatment options.Biotechnology has revolutionized the detection and management of rheumatic and immunological diseases, offering sophisticated tools and techniques for accurate diagnosis and personalized treatment.By harnessing advancements in genomics, proteomics, and immunology, biotechnology has enabled earlier detection, better understanding of disease mechanisms, and the development of targeted therapies.Here's an overview of how biotechnology has contributed to the detection of rheumatic and immunological diseases.There are several aspects of biotechnology which have helped in disease diagnosis in rheumatic and immunological diseases such as genomic biomarkers, biomarker panel, immunological assays, NGS, point care diagnostics, and precision medicine approaches.
GWAS have identified numerous genetic variants associated with susceptibility to auto-inflammatory diseases.GWAS have identified variants in genes encod ing components of the innate immune system, such as NLRP3, TNFAIP3, and IL1RN, which are implicated in disorders like cryopyrin-associated periodic syndromes (CAPS) and familial Mediterranean fever (FMF) (Xavier and Rioux 2008;Jain et al. 2021).Moreover, NGS technologies, including whole genome sequencing (WGS) and whole exome sequencing (WES), have revolutionized the ability to uncover rare genetic variants and mutations underlying auto inflam matory diseases (Satam et al. 2023;Fernandez-Marmiesse et al. 2018).NGS has been instrumental in identifying mutations in TNFRSF1A responsible for TNF receptor-associated periodic syndrome (TRAPS).GWAS and NGS have transformed our understanding of auto inflammatory diseases by discovery of genetic variants, disease stratification, and personalized medi cines.Over all, GWAS and NGS have revolutionized the field of auto-inflammatory diseases through the enhancing ge netic discovery, enabling precise disease stratification, and paving the way for personalized therapeutic strategies based on individual genetic profiles.
Biotechnology has facilitated the identification of genetic markers associated with rheumatic diseases such as rheumatoid arthritis (RA) and lupus.Genome-wide association studies (GWAS) have uncovered specific genetic variations linked to susceptibility and disease progression.For instance, a study by Plenge et al. (2007) identified the association between certain genetic variants in the HLA region and RA susceptibility, providing insights into the disease's pathogenesis.Biotechnological advancements have led to the development of multiplex biomarker panels for rheumatic diseases.These panels detect a combination of biomarkers, including autoantibodies, cytokines, and acute-phase proteins, providing a more comprehensive assessment of disease activity and prognosis.The use of biomarker panels has been shown to improve diagnostic accuracy and guide treatment decisions (Ingegnoli et al., 2014).Biotechnology has facilitated the development of highly sensitive immunological assays for detecting autoantibodies and immune complexes associated with rheu matic diseases.Techniques such as enzymelinked immunosorbent assay (ELISA), immunoblotting, and multiplex bead-based assays allow for the simultaneous detection of multiple autoantibodies, aiding in the differential diagnosis of conditions like systemic lupus erythematosus (SLE) and Sjögren's syndrome (Agmon-Levin et al. 2014).NGS technologies have enabled comprehensive analysis of the immune repertoire in patients with immunological diseases.By sequencing the variable regions of T-cell receptors (TCRs) and B-cell receptors (BCRs), researchers can characterize the diversity and clonality of immune cell populations, providing valuable insights into disease pathogenesis and identifying potential therapeutic targets (Mazzotti et al. 2022).Biotechnology has facilitated the development of point-of-care diagnostic devices for rapid and decentralized testing of rheumatic and immunological diseases.These devices leverage miniaturized biosensors and microfluidic platforms to detect biomarkers in patient samples with high sensitivity and specificity, enabling early intervention and improved patient outcomes (Firestein et al. 2014).Biotechnology has paved the way for precision medicine approaches in the management of rheumatic and immunological diseases.By integrating genetic, molecular, and clinical data, researchers can stratify patients into subgroups with distinct disease phenotypes and treatment responses.This personalized approach allows for the selection of optimal therapies based on individual patient characteristics, maximizing efficacy and minimizing adverse effects (Kuret et al. 2022).

REVIEW AND LITERATURE
A comprehensive review published in the Journal of Autoimmunity by Firestein GS highlights the pivotal role of biotechnological techniques in unraveling the complex pathogenesis of rheumatic diseases such as rheumatoid arthritis (RA) and systemic lupus erythe matosus (SLE).Through techniques like genome-wide association studies (GWAS), researchers have identified numerous genetic variants associated with disease susceptibility and severity (Firestein, 2019).Furthermore, a study published in Nature Reviews Rheumatology by Smolen et al. discusses the transfor mative impact of biologic therapies on the manage ment of rheumatic diseases.Biologics, including tumor necrosis factor-alpha (TNF-α) inhibitors and inter leukin-6 (IL-6) receptor antagonists, have revolu tion ized treatment by targeting specific inflammatory pathways with greater precision and efficacy than conventional therapies (Smolen et al. 2020).The bio tech nical advancements and the overview of impact on the diagnosis of rheumatic and immuno logical diseases, along with specific examples and citations supporting each advancement are illus trated (Table 1).
Multiplex immunoassays enable the simultaneous detection of multiple antibodies, cytokines, and other immune markers in patient samples.These assays offer high sensitivity and specificity, allowing for comprehensive profiling of immune system activity.They are particularly useful in diagnosing autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, and multiple sclerosis (Agmon-Levin N et al. 2014).NGS technologies allow for the comprehensive analysis of the immune repertoire, including T-cell receptors (TCRs) and B-cell receptors (BCRs).By sequencing the variable regions of these receptors, NGS facilitates the characterization of immune cell diversity and clonality, providing insights into disease pathogenesis and GWAS identify genetic variants associated with susceptibility to immunological disorders.By analyzing the genomes of large patient cohorts, GWAS reveal novel disease-associated loci and provide insights into the genetic basis of autoimmune and immune-mediated diseases (Okada et al. 2014).High-throughput flow cytometry enables quantitative analysis of immune cell subsets in patient samples.By measuring surface markers and intracellular proteins, flow cytometry provides valuable information about immune cell populations, aiding in the diagnosis of immune deficiencies and monitoring of disease progression (Goronzy et al. 2019).
