| pubmed-article:1808638 | pubmed:abstractText | Clinical and pathological findings were studied in 23 male patients with lupus nephritis who were followed up for a period of 41 +/- 36 months after renal biopsy. Age at renal biopsy was 31 +/- 14 years and 19 patients (83 per cent) were between 15 and 50 years old. C3 and C4 levels were below normal in 23 (100 per cent) and 16 (70 per cent) respectively, CH50 was less than 25 u/ml in 67 per cent, and antinuclear and anti-DNA antibodies were found in 87 per cent and 82 per cent respectively. Serum albumin level increased from 2.9 +/- 0.8 g/dl to 3.7 +/- 0.8 g/dl during the follow up period (p less than 0.01), while urinary protein decreased from 2.0 +/- 2.3 g/day to 1.4 +/- 2.5 g/day. There was a significant improvement in the degree of haematuria (p less than 0.01), but serum creatinine levels showed no change (mean 1.5 mg/ml). Active proliferative lupus nephritis of moderate or severe degree was observed in 65 per cent of patients at the initial biopsy. A trend to regression in this activity was seen in most serial biopsies, but the chronicity index showed a slight increase. These data demonstrate that systemic lupus erythematosus in males, in comparison to our previous report of the disease in female patients, is accompanied by more active nephritis, but that it follows a benign course with therapy. | lld:pubmed |
