title: Lipid parameters in a hyperendemic area for malaria.
abstract: BACKGROUND
  This is a cross-sectional study with the objective to analyze lipid parameters of individuals living in Brazilian Amazon, where malaria is endemic.
  
  
  METHODS
  The city chosen was Anajás in the state of Pará, Brazil, in Amazon region. The study analyzed lipid parameters of 46 subjects, 31 male and 15 female, aged between 20-60 years without malaria, and residents for more than five years in this city considered an area hyperendemic for disease. It was established three groups according to the number of previous episodes of malaria: group I (n = 22) one to five episodes, group II (n = 20) six to ten episodes and group III (n = 4) eleven to fifteen episodes. Total cholesterol, high density lipoprotein (HDL cholesterol), and low density lipoprotein (LDL cholesterol) were measured and was confected the thick smear for malaria of all individuals.
  
  
  RESULTS
  The hypocholesterolemia, the main characteristic of hyperendemic areas for malaria, was confirmed, but the mean of HDL cholesterol levels were 9.78% higher than the reference of World Health Organization.
  
  
  CONCLUSIONS
  Although other factors might have contributed to lipid profile, the constant exposure to infection by Plasmodium, according to the physiology of the parasite, may have played an important role in defining the lipid parameters observed for this region. Further studies, such as the case-control is needed to confirm this hypothesis.
