In this series of work, we examined the role of measuring cytokine mRNA expression in the urinary sediments for the assessment of SLE disease activity. The Th-1/Th-2 imbalance observed in patients with active lupus nephritis supports its relevance in pathogenesis. Our results also suggest that urinary T-BET-to-GATA-3 expression ratio may predict lupus flare. The measurement of mRNA expression in the urinary sediment may provide valuable information for the assessment and risk stratification of SLE patients. (Abstract shortened by UMI.) / In this series of work, we investigated (i) the pattern of cytokine gene expression in the urinary sediment of lupus patients, (ii) the relation between the gene expression profile in the urinary sediment and the clinical and histological disease activity of lupus patients; and (iii) the application of this non-invasive method on the assessment and monitoring of SLE disease activity. / Systemic lupus erythematosus (SLE) is a relapsing autoimmune disease with clinical manifestations that affect multiple organ systems. Lupus nephritis (LN) is recognized as one of the most severe organ involvement in SLE and affects half of the lupus patients. LN is characterized by intra-renal lymphocyte activation and inflammation. Since most of the cytokines exert their effects in a paracrine fashion, measuring their expression at the site of pathology should be of biologic relevance. Although kidney biopsy is widely used to determine the histology and severity of LN, this invasive procedure has its own risk and is not practical for serial monitoring. We hypothesize that measurement of messenger RNA (mRNA) expression in the urinary sediment may provide a non-invasive means to assess the disease activity of lupus patients. / Chan Wing Yan. / "August 2005." / Adviser: Cheuk Chun Szeto. / Source: Dissertation Abstracts International, Volume: 67-07, Section: B, page: 3692. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2005. / Includes bibliographical references (p. 302-333). / Electronic reproduction.
