Abstract
We prospectively studied 23 episodes of suspected alcoholic ketosis in order to learn whether there was objective evidence of the patients having stopped drinking ethanol a few days before admission, and of being starved. Eight patients had moderate ketosis (plasma 3-hydroxybutyrate 4.1-7.8 mmol/liter): seven patients had mild ketosis (2-4 mmol/liter); and eight had little or no ketosis (less than 2 mmol/liter). The latter eight patients had mainly lactic acidosis (plasma lactate 2.0-13.3 mmol/liter). Most of the ketotic patients did not have ethanol detected in their blood. The presence of starvation was supported by the finding of subnormal plasma triiodothyronine levels (less than 90 .mu.g/dl) in six of seven ketotic patients (average 60 .mu.g/dl for all seven). The ketotic patients usually had low-normal plasma insulin levels (3-16 .mu.U/ml), as is common in starvation. Our findings support the previously undocumented belief that most patients with alcoholic ketosis did stop drinking ethanol some time before admission, and that starvation is a major pathogenetic factor in the disorder.
