Profile of blood elements in leprosy patients.

ABSTRACT

Blood levels of 40 elements in 14 leprosy patients and 5 control subjects living near Mukinge Hospital in the North Western Province of Zambia were determined by spectrophotometry. In patients, compared to controls, serum levels of titanium, silicon, potassium and platinum were significantly higher; red cell levels of phosphorus were lower but those of antimony, bismuth, nickel, titanium, yttrium, silicon and platinum were higher; and whole blood levels of phosphorus, selenium, antimony and silver were lower. There were also significant differences in levels of certain elements when histologically active and inactive patients were compared and between the polar forms of leprosy. The data are consistent with a hypothesis of metabolic and nutritional involvement in the etiology of leprosy.
