In lupus-prone NZM2328 mice, a locus Cgnz1 on chromosome 1 was linked to chronic glomerulonephritis, severe proteinuria, and early mortality in females. A locus Adnz1 on chromosome 4 was linked to antinuclear antibody (ANA) and anti-double stranded DNA (dsDNA) antibody (Ab) production. In this investigation, two congenic strains, NZM2328.C57L/Jc1 (NZM.C57Lc1) and NZM2328.C57L/Jc4 (NZM.C57Lc4), ...

Systemic lupus erythematosus (SLE) predominantly affects women in their reproductive years. Renal disease (glomerulonephritis) is one of the most frequent and serious manifestations of SLE. Of the various histological types of lupus glomerulonephritis, diffuse proliferative nephritis carries the worst prognosis. Combined with high-dose prednisone, mycophenolate mofetil (MMF) has emerged as a fi...

R enal involvement is frequent in patients with systemic lupus erythematosus (SLE) and may strongly influence their expectancy and quality of life. Until recently, the treatment of lupus nephritis mainly rested on three drugs: corticosteroids, cyclophosphamide, and azathioprine. However, newer agents have been introduced in the last few years. In this paper, the available treatments for lupus n...

The C1q solid phase and Raji cell radioimmune assays were used to determine the frequency of detectable circulating immune complexes in patients with glomerulonephritis. In this study, 46% of 56 patients with glomerulonephritis had evidence of circulating immune complexes. More important, circulating immune complexes were associated with some, but not other, types of glomerulonephritis. Thus, i...

Systemic lupus erythematosus (SLE) is a systemic autoimmune syndrome defined by clinical and serologic features, including arthritis, glomerulonephritis, and certain autoantibodies such as anti-nuclear ribonucleoprotein (nRNP)/Smith antigen (Sm), DNA, and ribosomal P. Although lupus is considered primarily a genetic disorder, we recently demonstrated the induction of a syndrome strikingly simil...

A kidney biopsy was performed in 7 hypocomplementemic discoid lupus erythematosus patients despite the absence of overt renal involvement. Five patients had glomerular immune deposits and 2 patients with disseminated discoid lupus erythematosus exhibited definite proliferative glomerulonephritis. Those findings show that silent lupus nephritis may be encountered in discoid as well as in systemi...

nephritis remains an important problem in patients with systemic lupus erythematosus (sle). we conducted retrospective study to evaluate the efficiency of intravenous pulse cyclophosphamide in lupus nephritis: from 1983 to 1993, we reviewed 133 patients with biopsy proven lupus nephritis, 47 of them excluded because of short period of follow-up or defective laboratory data. eighty six patients ...

BACKGROUND Many children with kidney diseases can be diagnosed and treated without a biopsy. However, biopsy is a valuable method for the diagnostic and prognostic evaluation of children with kidney diseases. AIMS To evaluate the clinical and pathological profiles of the kidney biopsies in our department to provide epidemiological data for clinical practice. STUDY DESIGN Retrospective cross...
