High total and LDL cholesterol levels increased risk of chronic kidney disease

From Internal Medicine News, 23 July 2014:

MELBOURNE – Elevated total cholesterol and low-density lipoprotein cholesterol levels in patients with coronary heart disease were significantly associated with an increased risk of chronic kidney disease, according to a retrospective analysis of data from two large, randomized, controlled trials.

Data presented at the World Congress of Cardiology 2014 showed total cholesterol levels above 240 mg/dL were associated with a significant 78% increase in the risk of chronic kidney disease, while LDL cholesterol greater than 190 mg/dL was associated with a 72% increase in risk.

Elevated non–high-density lipoprotein cholesterol levels and the ratio of total cholesterol to HDL cholesterol were both associated with elevated risk of chronic kidney disease, but reduced HDL cholesterol and the ratio of apolipoprotein B/apolipoprotein A did not significantly affect risk.

Dyslipidemia is present in around 60% of patients with chronic kidney disease, noted presenter Dr. Prakash Deedwania, professor of medicine at the University of California, San Francisco. Previous studies in patients with coronary heart disease and chronic kidney disease also have shown that statins have a renoprotective effect.

However, Dr. Deedwania said there has been little exploration of the impact of baseline lipid parameters on renal function. Read more.
