Endogenous factors with biological and immunological activity similar to cardiac glycoside drugs (endogenous digitalis-like factors; EDLF) have been found in several tissues and body fluids of animals and humans. Detectable EDLF concentrations were found in blood and urine extracts of adults (normal healthy controls, hypertensive patients and salt-loaded healthy subjects), while higher levels were generally observed in plasma samples of pregnant women, newborns, and patients with renal insufficiency. The chemical characteristics of this endogenous factor are, at present, unknown, although it has been suggested that EDLF could be a substance with low molecular weight. Experimental studies and theoretical considerations suggest that EDLF, in addition to the ability to react with antibodies, might also bind to the specific cellular receptor of the cardiac glycosides and thus inhibit the membrane Na+/K(+)-ATPase (sodium pump). Therefore, it has been suggested that EDLF is an endogenous modulator of the membrane sodium-potassium pump, and that it could play a role in the regulation of fluids and electrolytes, in the myocardial muscular tone and also in the pathogenesis of hypertension.
