Patients with acne vulgaris, it has long been thought, are usually intolerant to carbohydrates. However, much recent evidence does not support such a view. Whereas earlier observations indicated that in many cases of acne borderline hyperglycemia is present, the majority of the more recent reports show that the sugar content of the blood of these patients does not differ significantly from that of normal subjects and that they show no evidence of a lack of tolerance to dextrose. In fact, the observation that the incidence of skin disorders was considerably less in a large series of diabetic patients than in a similar series of normal subjects led one investigator1 to treat patients with furunculosis with a high carbohydrate diet and dextrose injected intravenously. The results obtained were uniformly favorable.
The foregoing alleged beneficial effect of carbohydrate therapy on furunculosis suggests that this regimen might prove of value also in
