title: Variables discriminating between cryptogenic glomerular lesions in adults with the nephrotic syndrome.
abstract: A univariate analysis of individual clinical and biochemical values of adult patients with cryptogenic nephrotic syndrome has shown that significant differences exist between patients with proliferative glomerulonephritis, 'minimal change' nephritis and membranous nephropathy. For any given adult patient with the condition, the most likely clinical diagnosis is proliferative disease and the next, minimal change. These two diagnoses together account for most cases. The best clinical discriminants between them are the systolic blood pressure and plasma cholesterol concentration. If the systolic pressure is greater than 145 mm Hg proliferative disease is more likely, but if the cholesterol is greater than 530 mgm/100ml, a minimal change lesion is more likely. A scattergram for combining these variables in clinical practice is given, showing a zone of uncertainty where renal biopsy would be indicated. Although single variables do not permit discrimination between membranous nephropathy and the other two groups, it is suggested that analytical techniques where combinations of variables are used may be helpful, and should be developed.
