title: Frostbite: A Novel Presentation of Glucose-6-Phosphate Dehydrogenase Deficiency?
abstract: Acute hemolytic anemia (AHA) due to glucose 6-phosphate dehydrogenase (G6PD) deficiency has rarely been recognized as a contributor to the development of frostbite. We discuss a case of frostbite in a 32-year-old male Marine with G6PD deficiency during military training on Mount McKinley in Alaska, which eventually led to a permanent disability. In this report, the pathophysiology of G6PD deficiency, the effects of hemolytic anemia, and factors that contribute to frostbite will be discussed, as well as the clinical findings, treatment course, and the outcome of this case. The patient was evacuated and admitted to Alaska Regional Hospital. He was treated for fourth-degree frostbite, ultimately resulting in the complete or partial amputation of all toes. Although it cannot be proved that AHA occurred in this patient, this case potentially adds frostbite to the list of rare but possible clinical presentations of G6PD deficiency.
