title: Change in lipid profile in celiac disease: beneficial effect of gluten-free diet.
abstract: OBJECTIVE
  Celiac disease is associated with hypocholesterolemia, which is thought to contribute to a favorable cardiovascular risk profile. This led to suggestions that the diagnosis of celiac disease and its treatment with a gluten-free diet may result in elevation of the serum cholesterol level and worsen this risk profile. However, no study proves this in adults. We therefore examined the effect of a gluten-free diet on the lipid profile in patients with celiac disease.
  
  
  METHODS
  We identified 132 patients with celiac disease who adhered to a gluten-free diet and had lipid profiles performed before and after a median of 20.5 months on the diet. The patients lacked diseases that may affect serum lipids.
  
  
  RESULTS
  There were significant increases in total cholesterol and high-density lipoprotein (HDL) cholesterol (P < .0001) but not low-density lipoprotein (LDL) cholesterol (P=.06). The LDL/HDL ratio decreased by 0.36+/-0.7 (P < .0001). Both men and women had a significant increase in total cholesterol and HDL and a significant decrease in the LDL/HDL ratio. Only men had increases in LDL (P=.02). The greatest increase in lipid values was seen in those with the lowest initial values. The largest increase in HDL was seen in subjects with more severe disease as indicated by low albumin level and presence of total villous atrophy.
  
  
  CONCLUSIONS
  Diagnosis of celiac disease and its treatment with a gluten-free diet resulted in improvement in the lipoprotein profile, which included an increase in HDL and a decrease in the LDL/HDL ratio.
