About this study

Official title: Correlation Between Echocardiographic Parameters of Left Ventricular Diastolic Dysfunction and Inflammatory Biomarkers in Critically Ill Patients With Lupus Nephritis

This cross-sectional observational study aims to investigate the correlation between echocardiographic parameters of left ventricular diastolic dysfunction (E/A ratio, e', E/e' ratio, LAVI, and LVEF) and systemic inflammatory biomarkers (CRP, ESR, NLR, PLR, and SII) in critically ill patients with lupus nephritis. A total of 90 participants will be enrolled and divided into three groups: control group without SLE or lupus nephritis (n=30), SLE without lupus nephritis (n=30), and SLE with lupus nephritis (n=30). Transthoracic echocardiography and blood sampling for inflammatory biomarkers will be performed at baseline (ICU admission). The findings may help evaluate the potential role of these biomarkers in early cardiac risk assessment in this patient population.

Read the detailed description

Lupus nephritis is a frequent and severe manifestation of systemic lupus erythematosus (SLE) and often develops early in the disease course. Its pathophysiology is heterogeneous, driven by genetic, environmental, and immune-mediated mechanisms that produce inflammatory kidney injury. Despite therapeutic advances, lupus nephritis remains a major cause of chronic kidney disease, end-stage kidney disease, death, and reduced quality of life.

Lupus nephritis can promote heart failure through intertwined inflammatory, renal, vascular, and hemodynamic pathways. Patients with SLE have increased heart failure risk, and cardiovascular risk is higher when nephritis is present. Renal impairment and proteinuria in lupus nephritis are linked to hypertension, dyslipidemia, endothelial dysfunction, and prothrombotic tendency, which can accelerate myocardial remodeling and dysfunction. Lupus nephritis directly causes diastolic heart failure through systemic inflammation and immune-complex deposition that produce interstitial myocardial fibrosis, edema, and diastolic dysfunction.

This study addresses an important gap in patients with lupus nephritis, where subclinical myocardial dysfunction is increasingly recognized but poorly characterized in critically ill patients. Echocardiographic and tissue Doppler abnormalities correlate with inflammatory biomarkers such as CXCL10 and sST2 in SLE. Lupus nephritis is also associated with more severe myocardial involvement and higher inflammatory burden than extra-renal disease. However, adult intensive-care data linking left ventricular diastolic dysfunction parameters with systemic inflammatory biomarkers in lupus nephritis remain limited.

This cross-sectional observational study will enroll 90 participants divided into three groups: control group without SLE or lupus nephritis (n=30), SLE without lupus nephritis (n=30), and SLE with lupus nephritis (n=30). Participants will undergo comprehensive clinical assessment, transthoracic echocardiography to assess left ventricular diastolic function (E/A ratio, e', E/e' ratio, LAVI, and LVEF), and blood sampling for inflammatory biomarkers (CRP, ESR, NLR, PLR, and SII). Disease activity will be assessed using the SLEDAI-2K score, and renal function will be assessed by eGFR and CKD stage. The correlation between echocardiographic diastolic parameters and inflammatory biomarkers will be determined, and independent predictors of diastolic dysfunction will be identified.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Correlation Between Echocardiographic Diastolic Parameters and Inflammatory Biomarkers

    Correlation coefficient between echocardiographic parameters of left ventricular diastolic dysfunction (E/A ratio, e', E/e' ratio, LAVI, and LVEF) and systemic inflammatory biomarkers (CRP and ESR) in critically ill patients with lupus nephritis, assessed by Pearson's or Spearman's correlation coefficient.

    Measured: Baseline (at ICU admission)

Secondary outcomes (6)
  1. Mean E/A Ratio

    Mean early-to-late diastolic filling velocity ratio (E/A) measured by transthoracic echocardiography.

    Measured: Baseline (at ICU admission)

  2. Mean E/e' Ratio

    Mean ratio of early mitral inflow velocity to early diastolic mitral annular velocity (E/e') measured by tissue Doppler echocardiography.

    Measured: Baseline (at ICU admission)

  3. Mean Left Atrial Volume Index (LAVI)

    Mean left atrial volume index in mL/m² measured by transthoracic echocardiography.

    Measured: Baseline (at ICU admission)

  4. Mean C-Reactive Protein (CRP) Level

    Mean serum C-reactive protein level in mg/L measured by immunoturbidimetry.

    Measured: Baseline (at ICU admission)

  5. Mean Neutrophil-to-Lymphocyte Ratio (NLR)

    Mean neutrophil-to-lymphocyte ratio calculated from complete blood count.

    Measured: Baseline (at ICU admission)

  6. Mean SLEDAI-2K Score

    Mean Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score. Scores range from 0 to 105, with higher scores indicating greater disease activity.

    Measured: Baseline (at ICU admission)

Questions about this trial

What is this clinical trial studying?

An observational study of Lupus Nephritis and Diastolic Dysfunction, run by Assiut University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 24 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Alaa M Abdelaal, Resident (01156604132, Alaa.18313526@med.aun.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Correlation Between Echocardiographic Diastolic Parameters and Inflammatory Biomarkers (time frame: Baseline (at ICU admission)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Sep 2026.
