Cholesterol Counts in Kidney Disease Patients
Patients with CKD often develop and die from cardiovascular disease (CVD). While it's well known that high cholesterol puts people at risk for CVD in the general population, the relationship is not so clear in CKD patients. In fact, research has shown that dialysis patients with higher cholesterol levels die at a lower rate than those with lower cholesterol levels. It's not that high cholesterol is beneficial; rather, it may indicate a lesser degree of malnutrition and inflammation, two serious and interrelated complications of kidney disease.
To see whether malnutrition and/or inflammation might modify the relationship of cholesterol and CVD, Gabriel Contreras MD MPH (University of Miami Miller School of Medicine), senior author Lawrence Appel, MD (Welch Center for Prevention, Epidemiology and Prevention, Johns Hopkins Medical Institutions), and colleagues studied 990 African-Americans with hypertension and CKD who were not yet on dialysis, 31% of whom had malnutrition and/or inflammation. Over the course of 12 years, 20% of patients experienced a new CVD event such as heart attack, stroke, congestive heart failure, or death from heart disease, with similar numbers in the groups with (19%) and without malnutrition and/or inflammation (21%). In the patients with malnutrition and/or inflammation, high blood cholesterol levels were not associated with CVD events; however, in the patients without malnutrition and/or inflammation (69%), patients' risk of developing a new CVD event increased as cholesterol levels rose. (Compared to patients with cholesterol levels less than 200 mg/dL, patients with cholesterol levels between 200 and 239 mg/dL had a 1.19-fold increased risk; those with cholesterol levels of 240 mg/dL or more had a 2.18-fold increased risk.)
