The Dahl salt-sensitive rat (DS) is a model of genetically determined arterial hypertension exacerbated by dietary salt. We report two additional abnormalities of DS rats, which are both genetically determined and enhanced by salt: 1) immunoglobulin disorders and 2) renal dysfunctions. These abnormalities precede and are not the result of the arterial hypertension. In young, prehypertensive DS rats the plasma and tissue concentrations of immunoglobulin (Ig) G, but not of IgM or IgA, are decreased compared with those of the salt-resistant strain (DR). A high-salt diet (8.0% NaCl) decreases the plasma and tissue IgG levels of DS but not of DR rats. Reduction of IgG in the DS strain results from both decreased synthesis and increased urinary excretion. Renal dysfunction in young, prehypertensive DS animals is manifested by increased excretion of high molecular weight proteins, including albumin, IgG, IgA, and IgM. The high-salt diet increases the urinary excretion of these proteins within 1-2 days, and the effect is much greater in DS compared with DR rats. The urinary excretion of IgG is selectively increased relative to immunoglobulin light chains, IgA and IgM in DS compared with DR animals. The present studies provide new markers characteristic of the DS phenotype and pose the issue of possible genetic or functional interrelationships among the salt-sensitive hypertension, immunoglobulin disorders, and renal dysfunctions.
