  Purpose

Hyperlipidemia and atherosclerosis lead to cardiovascular diseases and are an indirect cause of increased death rate in the general population. This association is still more evident in specific subpopulations, like patients with advanced chronic kidney disease (CKD), especially hemodialysis (HD) patients, due to a higher prevalence of lipid disturbances and atherosclerosis compared to the general population. Cardiovascular events in CKD patients are frequently associated with traditional risk factors, including diabetes, male sex, hypertension, dyslipidemia and advanced age. However, these factors failed to fully account for the increased risk of cardiovascular events in CKD. The efforts are made to identify new risk factors that contribute to the development of atherosclerosis and participate in causes of cardiovascular death. In 2003, there were identified peptides designated salusin-alpha and salusin-beta. Development of atherosclerosis may be suppressed by salusin-alpha. Salusin-alpha may have a lipid lowering effect, similar to that of statins.

The purpose of this study is to investigate whether 1) salusin-alpha is associated with lipid metabolism of HD patients (without or with metabolic syndrome or type 2 diabetes mellitus), similarly or not like in healthy or obese subjects; 2) treatment with atorvastatin and its effects are associated with changes in plasma salusin-alpha concentration, if so - whether it is dependent on the direct influence of atorvastatin on salusin-alpha or associated with a decrease in serum lipid level; 3) salusin-alpha may predict mortality in HD patients.

Primary Outcome Measures:
  • normalization of serum LDL cholesterol [ Time Frame: 30 weeks ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 310
Study Start Date: October 2011
Estimated Study Completion Date: December 2016
Estimated Primary Completion Date: October 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: atorvastatin

The prospective, randomized, double-blind, placebo-controlled study:

  • will be preceded by one month non-pharmacological treatment of hyperlipidemia (prerandomization phase)
  • 130 hyperlipidemic hemodialysis (HD) patients will be randomly assigned to receive blinded study drug: 65 patients will be allocated to start with atorvastatin and 65 patients - with placebo.

Atorvastatin will be administered and monitored according to the K/DOQI guidelines (2003).

The prospective, observational study:

- 35 hyperlipidemic patients will be followed for 30 weeks on the prescribed non-pharmacological treatment of hyperlipidemia

Drug: Atorvastatin

Atorvastatin (10 - 80 mg/day) will be administered orally in the one evening dose in the case of strict indications for such a treatment. Before starting atorvastatin, serum lipid profile will be examined two times, and when both results are abnormal the treatment is started. Duration of administration:

  • atorvastatin 12 weeks, 6 weeks washout, placebo 12 weeks or
  • placebo 12 weeks,6 weeks washout,atorvastatin 12 weeks.
Other Name: ATC: C 10 AA 05
No Intervention: Lifestyle counseling

Protocol of the prospective study in obese persons:

  • after taking the anthropometric measurements and collecting a blood sample, the start of weight lowering therapy with a prescribed diet and planned physical activity
  • follow-up for 30 weeks (measurement of body weight every week).
No Intervention: The controls (healthy volunteers)
