A Trial of Rosuvastatin in Systemic Lupus Erythematosus
|ClinicalTrials.gov Identifier: NCT01170585|
Recruitment Status : Completed
First Posted : July 27, 2010
Last Update Posted : June 23, 2015
Systemic Lupus Erythematosus (SLE) is a condition that affects the whole body. It can cause inflammation of the blood vessels resulting in an earlier thickening and hardening of the arteries resulting in strokes. It has been reported that SLE can worsen the function resulting in heart failure.
The aim of the study is to examine what effects Rosuvastatin, a cholesterol lowering drug, given to patients has on the degree of thickening of the arteries over the course of two years. We also want to see how it affects the function of the blood vessels and also of the heart.
Individuals who agree to participate will be randomly assigned into two groups. One group will be given the active drug whereas the other will have a placebo. Subjects in the study will all have a cardiac magnetic resonance (CMR) scan before treatment, at 1 year and then 2 years at the end of the treatment. Each scan will involve imaging the carotid arteries in the neck, the arteries in the arm and also the heart. Individuals will continue to have regular out-patient reviews by their own team of doctors, regular blood tests will be taken to monitor the disease and also to ensure the safety and well being of the individual.
At the end of the 2 year study we hope that we will be able to slow down the rate of arterial thickening and retard any plaque build up in the arteries. We also want to see what effect rosuvastatin has on heart function. Ultimately, we hope to prove that people with SLE should be treated with a cholesterol lowering drug as part of their routine treatment.

- Change from baseline in bilateral carotid artery wall volume and distensibility [ Time Frame: 3 CMR of 24 months (baseline; 12 and 24 mnths) ]
A series of 20 contiguous 2 dimensional images, centred about the carotid bifurcation will be obtained. These images are then used to calculate the vessel area, but because they are contiguous a three dimensional structure can be formed and the vessel volume can be calculated. These values can be plotted against age and sex-matched graphs of normal ranges.
The carotid artery distensibility will be calculated by obtaining a short cine film of the carotid artery as it pulsates. This can be contoured in the diastolic and systolic phases of the cardiac cycle.
- Endothelial function assessed by brachial artery reactivity. [ Time Frame: 3 CMR, baseline; 12 and 24 mnths. ]Endothelial function is assessed by imaging the area of the brachial artery at baseline & post intervention.Endothelial dependent function will be assessed by inflating a blood pressure cuff around the forearm for 5 minutes to occlude arterial blood flow and create hyperaemia on release which induces brachial artery dilation by shear effects on endothelium.Glyceryl trinitrate spray will be given to the patient, and further images will be obtained.Both sets of images will be compared to the baseline and the percentage change in vessel size calculated providing a measure of endothelial function.
- Correlation of vascular findings to ventricular volumes and function [ Time Frame: baseline; 12 and 24 months ]The correlation of ventricular indices in SLE patients is determined through assessment of cardiac function. Patients will have left and right ventricular volumes measured, allowing calculation of the ejection fraction. These will be compared with age and sex matched normal subjects
