Abnormalities of prostanoid metabolism, which may affect renal function, were studied in lupus nephritis. The subjects were 31 patients with lupus nephritis, ten with non-renal SLE, and four with renal, non-SLE collagen disease. Urinary levels of various prostanoids, thromboxane B2(TXB2), 11-dehydro-TXB2, 6-keto-PGF1 alpha,2,3-dinor-6-keto-PGF1 alpha and PGE2, and plasma level of 11-dehydro-TXB...
BACKGROUND AND OBJECTIVES The prevalence and significance of remission and relapse in children, adolescents, and young adults with lupus nephritis in the United States are poorly understood. Patterns and predictors of disease progression in a southeastern U.S. pediatric cohort with severe lupus nephritis are presented. DESIGN, SETTINGS, PARTICIPANTS, & MEASUREMENTS Individuals age 21 or less ...
This study investigated the relationship between urinary protein excretion in lupus nephritis New Zealand black mice and renal pathology. A total of 328 lupus nephritis New Zealand black mice were established by a backcross hybridization method, and renal pathology was determined. The urinary protein excretion of the backcross mice over 24 h was compared and analyzed. Urinary protein excretion ...
The occurrence of nephritis in patients with systemic lupus erythematosus is associated with increased morbidity and mortality. The pathogenesis of lupus nephritis is complex, involving innate and adaptive cellular and humoral immune responses. Autoantibodies in particular have been shown to be critical in the initiation and progression of renal injury, via interactions with both Fc-receptors a...
Interleukin 23 receptor expressing IL-17 producing T cells have been shown to be important in the development of murine lupus. The usefulness of IL-23 inhibition in ameliorating lupus nephritis is unknown. We hypothesized that inhibition of IL-23 will ameliorate nephritis in lupus-prone mice. To this end, we treated MRL/lpr lupus-prone mice for 6 weeks with a rat anti-IL-23p19 antibody, which r...
Lupus nephritis is a frequent manifestation of systemic lupus erythematous. Lupus nephritis usually presents with abnormal urinalysis, proteinuria, and/or renal insufficiency. We report a case of a 48-year-old woman who underwent partial nephrectomy for a fortuitously discovered solid enhancing left kidney mass. No neoplastic cells were found in the biopsy specimen; however, the pathology findi...
Lupus nephritis develops from a combination of genetic and environmental factors such as microbial infection. A role for microbial nucleic acids (e.g., via nucleic acid-specific Toll-like receptors [TLR]) was hypothesized, in this context, because microbial nucleic acids can trigger multiple aspects of autoimmunity in vitro and in vivo. Eight-week-old MRL(lpr/lpr) and MRL wild-type mice receive...
BACKGROUND AND OBJECTIVES Although the accepted standard of care for induction of lupus nephritis has been cyclophosphamide, recent trials suggest that mycophenolate mofetil may be as or more effective and less toxic. A systematic review and meta-analysis were performed to determine the risk for failure to induce remission of lupus nephritis in patients who were treated with mycophenolate mofet...
Macrophages mediate kidney disease and are prominent in a mouse model (MRL-Fas(lpr)) of lupus nephritis. Colony stimulating factor-1 (CSF-1) is the primary growth factor for macrophages, and CSF-1 deficiency protects MRL-Fas(lpr) mice from kidney disease and systemic illness. Whether this renoprotection derives from a reduction of macrophages and whether systemic CSF-1, as opposed to intrarenal...
BACKGROUND AND OBJECTIVES Lupus nephritis is a classic immune complex glomerulonephritis. In contrast, antineutrophil cytoplasmic antibodies are associated with necrotizing and crescentic glomerulonephritis, in the absence of significant immune deposits. Antineutrophil cytoplasmic antibodies are detected by indirect immunofluorescence in 20% of patients with systemic lupus erythematosus. We rep...
