Premature Atherosclerosis in Systemic Lupus Erythematosus (PASLE)

July 29, 2019 updated by: Peking Union Medical College Hospital

Premature Atherosclerosis in Systemic Lupus Erythematosus: a Prospective Cohort Study

Patients with SLE have increased rates of atherosclerosis, while the risk factors for atherosclerosis in those patients were not fully revealed. This study is an observational study to investigate the natural process and risk factors for atherosclerosis based on a Chinese SLE cohort. Carotid intima media thickness (CIMT) and brachial-ankle pulse wave velocity (baPWV) will be measured for each patient at baseline and 5-year follow-up. Blood tests including cholesterol levels, fasting plasma glucose levels and etc. will also be performed.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Accelerated atherosclerosis is a major complication of systemic lupus erythematosus (SLE), and it leads to increased cardiovascular morbidity and mortality in patients with SLE. Prevention and intervention of premature atherosclerosis is beneficial for prognosis and survival of patients with SLE.

The primary aim of this study was to investigate the natural progress of carotid intima media thickness (CIMT) in 5 years, and examine the risk factors for progression of CIMT and atherosclerotic plaques based on a Chinese SLE cohort. The secondary aims of the study were to investigate progression of brachial-ankle pulse wave velocity (baPWV), and to examine the risk factors for increasing baPWV in patients with SLE.

Based on sample size calculation, 440 patients who meet the eligibility criteria will be enrolled in this study. All patients will be enrolled from Peking Union Medical College Hospital. After informed consent is obtained, the patients will be comprehensively evaluated from demographic characteristics, medical history, clinical assessments, laboratory tests results, CIMT and baPWV at baseline and 5-year follow-up. Descriptive analysis, univariate analysis, and multivariate analysis will be used to analyze the correlation between potential risk factors and CIMT/baPWV.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

The target population was patients with the clinical diagnosis of SLE. Study participants were recruited through a nationwide registry system created by the Chinese SLE Treatment and Research group. All patients were continuously enrolled as outpatients of the Department of Rheumatology in Peking Union Medical College Hospital (PUMCH), which is a renowned hospital in China.

Description

Inclusion Criteria:

  • Age≥18 years
  • Fulfillment of clinical classification criteria of SLE (four or more 1997 American College of Rheumatology classification criteria)
  • Provision of signed written informed consent

Exclusion Criteria:

  • Clinically overt coronary artery disease
  • A history of cardiovascular disease (previous stroke, heart failure, myocardial infarction, angina, or symptomatic PAD)
  • Malignancy
  • Pregnant/lactating women

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
quantitative change in CIMT from baseline
Time Frame: Year 5
quantitative changes in CIMT at 5-year follow-up from baseline will be documented
Year 5

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
quantitative change in baPWV from baseline
Time Frame: Year 5
quantitative changes in baPWV at 5-year follow-up from baseline will be documented
Year 5
Major cardiovascular events
Time Frame: 5 years
the prevalence rate of nonfatal stroke, nonfatal myocardial infarction, and cardiovascular death
5 years

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
