title: Lipoprotein(a) in 505 hospitalized patients with various pathological states: correlations with cardiovascular diseases and therapies.
abstract: OBJECTIVE
  Our aim was to study the lipoprotein (a) (Lp(a)) levels in various pathological states.
  
  
  METHODS
  This investigation was prospective and included a healthy control group.
  
  
  METHODS
  This study was carried out in two internal medicine and angiology services in teaching hospitals.
  
  
  METHODS
  505 patients were included with various diseases: 66 acute infections, 9 HIV infections, 25 cancers, 86 diabetes, 36 systemic diseases, 94 atheromatous vascular disease, 27 arterial hypertensions. A control group was composed of 21 healthy subjects.
  
  
  METHODS
  There was no therapeutic intervention but cardiovascular treatments were recorded.
  
  
  METHODS
  Serum Lp(a), total cholesterol, triglycerides, HDL-cholesterol, calculated LDL-cholesterol, apolipoproteins A-I and B were measured together with inflammatory parameters, serum creatinine, proteinuria, serum aminotransferase activity.
  
  
  RESULTS
  There was no difference in Lp(a) levels between controls and each patient group. However, a correlation was found in systemic diseases between Lp(a) and C reactive protein (r = 0.371, p = 0.026) or serum albumin concentration (r = 0.453, p = 0.006). In hypertension, Lp(a) correlated with serum creatinine (r = 0.420, p = 0.03). In the whole patient population, Lp(a) was correlated with cholesterol (r = 0.156, p = 0.0001), apolipoprotein B (r = 0.215, p = 0.0001), age (r = 0.108, p = 0.015), arterial events (r = 0.174, p = 0.0001) and platelet anti-aggregant drugs (r = 0.169, p = 0.0001).
  
  
  CONCLUSIONS
  Lp(a), was related to atheromatous events and in systemic diseases to inflammation, suggesting that Lp(a) might vary in some patients in a manner similar to acute phase proteins.
