A case of transcutaneous
diethylene glycol poisoning with severe
acute kidney injury, but a positive outcome, is described. A man without significant medical history was admitted to our hospital due to
anuria, gastrointestinal symptoms, and
hypertension. Ultrasonography excluded vascular damage and postrenal obstruction. Laboratory tests showed
acute kidney injury and
metabolic acidosis with increased anion gap;
hemodialysis therapy was started. The brother of the patient reported that the patient had been smearing his skin with brake fluid containing
diethylene glycol to treat a "
dermatitis." Only supportive
therapy was given due to the lack of a specific
antidote.
Continuous venovenous hemofiltration was performed. The kidney biopsy showed acute toxic proximal tubulonecrosis, without deposition of
oxalate crystals. His neurologic condition worsened dramatically; supportive care was continued. Over time,
acute kidney injury and neurologic damage gradually improved; 33 days after admission, he went to a rehabilitation unit for 5 months, with complete clinical recovery. Historically,
diethylene glycol has been the cause of large-scale
poisonings from ingestion of contaminated drugs. The clinical evolution is unpredictable. Treatment is not well defined; early
hemodialysis treatment reduces levels of toxic metabolites, and
fomepizole could be useful in cases with an early diagnosis. A comparison of the characteristics of
diethylene glycol versus
ethylene glycol poisoning is given.
