[Functional state of the kidneys in patients with chronic diffuse bronchitis]

Radionuclide renography and enzyme immunoassay used to evaluate renal function and renin--angiotensin--aldosterone system in 95 patients with chronic diffuse bronchitis demonstrate impairment of renal secretion and excretion in all the examinees. There are shifts in plasma renin activity and aldosterone concentration. The above defects depend on cardial--pulmonary insufficiency and respiratory--hemodynamic disorders.
