Delayed sensorimotor neuropathy and renal failure: an additional report in a patient with diethylene glycol poisoning

Dear Editor, We previously reported a case of delayed autonomic neuropathy in a patient with diethylene glycol (DEG) poisoning, and would like to emphasize two characteristic complications, sensorimotor neuropathy and renal failure, occurring in the same case, because of their severity and possible reversibility. Although once recovered from acute symptoms by day 3, the patient suffered from long-term ventilator dependence (days 11–54), unresponsiveness, and quadriparesis. Despite no remarkable finding on brain magnetic resonance imaging, electroencephalogram, or lumber puncture, a nerve conduction study showed reductions in the amplitudes and conduction velocities of compound muscle and sensory nerve action potentials in the limbs (Table 1). The patient recovered from all neurological symptoms within 2 years of exposure to DEG. Sensorimotor neuropathy from DEG poisoning can be delayed until at least 5–10 days
