[Facial vasomotor flushing due to alcohol-chlorpropamide. Prevalence in diabetic and non-diabetic patients].

Using a standard test (sherry 40 ml 12 hours and 36 hours after 250 mg chlorpropamide), chlorpropamide-alcohol flush (CPAF) prevalence was 34 p. 100 (19/56) in non insulin-dependent diabetics (NIDD), 10 p. 100 (3/30) in insulin-dependent diabetics and 7 p. 100 (2/27) in controls. Family history of diabetes was not associated with CPAF trait. Conflicting results in the literature might be explained by bias in patients selection or methodology.
