Armanni-Ebstein Lesions in Terminal Hyperglycemia.

Armanni-Ebstein lesions (AEL) occur in deaths related to uncontrolled diabetes mellitus. To investigate the relationship between AEL and terminal hyperglycemia, we retrospectively reviewed 71 cases with vitreous glucose levels ≥11.1 mmol/L; 27 (38%) cases had AEL (vitreous glucose 14.0-77.3 mmol/L); and 44 cases (62%) did not (vitreous glucose 11.1-91.9 mmol/L). There was no significant difference (p = 0.271) in vitreous glucose levels between the cases with AEL (mean 39.2, SD 16.7 mmol/L) and those without (mean 34.2, SD 19.8 mmol/L). Similarly, there was no difference in the degree of dehydration, renal failure, or osmolality. However, there was a significantly higher level of β-hydroxybutyrate among the cases with AEL compared to those without (p = 0.007), suggesting that ketoacidosis may facilitate the development of AEL. Given the possible synergistic role of β-hydroxybutyrate, the correlation between AEL and terminal hyperglycemia in animal studies may not be applicable to humans. AEL may also possibly occur with sublethal elevations in glucose.
