Abstract
Intravenous dimethylsulfoxide (DMSO) was used to treat seven patients with stable spinal cord injuries. Because of drug-associated hemoglobinemia and hemoglobinuria, the patients were studied for subtle evidence of renal tubular dysfunction by serial measurements of urinary beta-2-microglobulin excretion. No increases in tubular protein excretion or decreases in glomerular filtration rate were observed following short-term infusions of 10-40% DMSO. It is concluded that there is no significant short-term nephrotoxicity from intravenous DMSO.
