[Proteinuria in the aged]

The Authors for a better knowledge of the senile kidney have studied the urinary proteins of a group of elderly people resident in a geriatric institute. For instance they have noted the percentage of proteinuria in the urine of 313 patients (M and F) with various pathology, making also an electrophoresis of the urinary proteins. They put in evidence that the subjects with proteinuria were older than others, without proteinuria, and noted the high incidence of the infectious diseases of the urinary tract in these patients. In a second time the urine of 247 apparently healthy elderly people has been studied. Through an accurate examination (that is comprehensive of some serum parameters and a comparison with subjects without proteinuria) the Authors discussed a way of growing old defined "with biological trouble".
