title: Prevalence and treatment of hyperlipidemia in patients with chronic hepatitis C infection.
abstract: BACKGROUND
  Patients with chronic hepatitis C (HCV) infection can also have hyperlipidemia. Glucose intolerance has been associated with HCV infection and treating hyperlipidemia in this and other high-risk groups is warranted. We hypothesized that hyperlipidemia is common in patients with hepatitis C and that it is under-treated for fear of worsening liver function.
  
  
  METHODS
  From the Stratton Veterans Affairs Medical Center computerized database, we collected information on patients with HCV infection enrolled in hepatology clinic. We collected information on age, sex, duration of HCV infection, concomitant diagnoses, medications they were on, laboratory values including hepatic function, glucose, and lipid levels. We collected information on the lipid levels and various cardiovascular risk factors.
  
  
  METHODS
  This is a retrospective study involving record review. We analyzed the data collected from the records for prevalence of high cholesterol (as defined by the National Cholesterol Education Program) and for prevalence of various cardiovascular risk factors. We analyzed prevalence of treatment of hyperlipidemia in various risk groups. In the patients who were treated for hyperlipidemia, we collected information on any worsening hepatic function that led to treatment discontinuation.
  
  
  RESULTS
  Six hundred and twenty-eight (70.5%) out of 891 patients with hepatitis C had hyperlipidemia. Of the 628 patients who had hyperlipidemia, 81 (12.7%) had positive antibody and RNA not tested; 162 (25.4%) had positive antibody but negative RNA testing; and 385 (61.3%) had positive testing for viral RNA. Two hundred and eighty-four (45.2%) of 628 patients with hyperlipidemia were eligible for treatment to lower it. Of 146 patients with hyperlipidemia and diabetes mellitus or arterial disease who were qualified for treatment (LDL >99), 95 (65.1%) were treated with lipid-lowering medication. Of 148 patients with hyperlipidemia and without diabetes or arterial disease who were qualified for treatment, 64 (43.3%) were treated with lipid-lowering medication.
  
  
  CONCLUSIONS
  A high prevalence of hyperlipidemia in patients infected with HCV is observed. Prevalence is highest among those who are positive for viral RNA. About half the patients with hyperlipidemia were eligible for treatment with drugs to lower it. Treatment of hyperlipidemia with medication though surprisingly common could improve.
