title: Effect of weight loss on serum lipoprotein(a) concentrations in an obese population.
abstract: To assess the distribution of serum concentrations of the atherogenic lipoprotein(a) [Lp(a)] in an obese population and the possible effects of weight reduction, we determined Lp(a) in 52 white, moderately obese subjects (16 men and 36 women). The subjects were participating in a weight-reduction program of diet, exercise, and behavior modification plus combination anorectic drug therapy (fenfluramine and phentermine). This placebo-controlled, double-blind study lasted 104 weeks. We also determined concentrations of fasting insulin, triglycerides, total cholesterol, high-density lipoprotein cholesterol, apolipoprotein (apo) A-I, low-density lipoprotein cholesterol, and apo B. Results showed the following: a highly skewed, nongaussian distribution of serum Lp(a) values in the obese population, virtually identical to that reported for healthy adults; no clinically significant change in Lp(a) concentrations with weight loss; and further evidence of normalization of insulin, lipid, and lipoprotein concentrations with weight loss.
