D-lactic acidosis sometimes occurs in malabsorbed patients with short-bowel syndrome and is characterized by recurrent episodes of encephalopathy and metabolic acidosis. The characteristic neurologic abnormalities and the presence of metabolic acidosis raises a diagnostic suspicion, and the diagnosis is made when the serum level of D-lactic acid is greater than 3 mmol/L. ⋯ The authors present a case of D-lactic acidosis in a 22-year-old patient with short-bowel syndrome, to whom intestinal bacterial agents (probiotics) were given in addition to oral kanamycin. Recolonization of the intestine with nonpathogenic floras should be a long-term treatment for D-lactic acidosis.
