Hair zinc compared with plasma zinc in uremic patients before and during regular hemodialysis.
Plasma and hair zinc concentrations were measured by atomic absorption spectrophotometry in 34 control subjects, 20 nondialyzed uremic patients and 18 patients treated with regular hemodialysis. Plasma zinc levels were low in both nondialyzed and hemodialyzed patients. Hair zinc levels were low in the nondialyzed uremics, but at least partialy restored to normal in patients on hemodialysis. In both patient groups, hair zinc was positively correlated with plasma zinc. In the nondialyzed patients haie zinc depletion in end-stage renal disease progresses with increasing degree of renal insufficiency and tends to be reversed by regular hemodialysis.
