OBJECTIVE: Acrocyanosis (AC) is a common manifestation of starving syndrome in anorexia nervosa. We characterized microvascular changes associated with AC and determined discriminating factors between acrally symptomatic and nonsymptomatic patients. METHODS: We examined 34 patients with anorexia nervosa (15 restrictive-anorectic type, 19 binge-eating/purging type, duration 1-25 years). Nineteen were symptomatic (SP) and 15 were nonsymptomatic (NSP). All underwent photo-pletysmography, sonography of the brachial artery, capillary microscopy and laboratory analysis. RESULTS: Disease characteristics and body mass index did not differ between SP and NSP. In SP more dilated efferent capillary loops and venoles were present (P<.001) and capillary flow velocities were reduced (0.21+/-0.12 ml/min vs. 0.34+/-0.15 ml/min; P=.015). Flow-mediated and nitroglycerin-induced dilatation showed no differences. Symptomatic patients had lower leukocyte counts (P=.008), lower eosinophils (P=.003) and lower LDL (P=.045) concentrations. A logistic regression model identified only leukocytes (P=.017) and eosinophils (P=.023) to be associated with AC. CONCLUSIONS: In acrally symptomatic patients the typical microvascular features of AC are present. AC is associated with lower leukocyte counts and lower eosinophils.
