Effect of diet intervention and oral zinc supplementation on metabolic control in Berardinelli-Seip syndrome.

Background/aims: Berardinelli-Seip syndrome (BSS), also termed congenital generalized lipodystrophy or congenital generalized lipoatropic diabetes, is a rare autosomal recessive disease characterized by the nearly complete absence of metabolically active adipose tissue from birth, extreme insulin resistance, diabetes mellitus, and hepatomegaly. The aim of this study was to evaluate the effect of diet intervention and oral zinc supplementation on the metabolic control of BSS patients.

Methods: During a 3-month period, 10 BSS patients received individualized diets and oral zinc supplementation.

Effects of zinc supplementation in patients with type 1 diabetes.

The purpose of this study was to identify the effect of oral zinc supplementation in patients with type 1 diabetes (T1DM) on metabolic control and zinc blood concentrations. The sample consisted of 20 patients with T1DM and a control group (n=17). Metabolic control was evaluated by glycemia at fast, 24 h glycosuria, and HbA1c.
