Impaired renal tubular function in chronic alcoholics

Despite the well known effects of chronic alcohol abuse on the gastrointestinal, cardiovascular, nervous and endocrine systems, little information is available on its effect on renal function. To assess renal function we measured urinary excretion of albumin, alpha 1 microglobulin and retinol binding protein in 30 chronic alcoholic patients. Our data shows that 40% of chronic alcoholic patients have impaired renal tubular function.
