Acute renal failure in accidental hypothermia of cold water immersion
1998
Abstract We report a 27-year-old Japanese man who developed acute renal failure associated with cold water immersion. The clinical course was consistent with that of acute renal failure attributable to acute tubular necrosis. A renal biopsy specimen showed patchy and focal loss of tubule cells, necrotic epithelium, interstitial edema, and arterial lumina obstructed by diffuse and severe intimal thickening. Endothelin increased more than five times in the early phase of the clinical course. Vasoconstriction and ischemia induced by cold exposure seem to lead to endothelin release. Endothelin may be related to the development of acute renal failure and intimal thickening. (Am J Kidney Dis 1998 May;31(5):856-9)
