About this study

Official title: Neutrophil to Lymphocyte Ratio in Acute Exacerbation of Chronic Obstructive Pulmonary Disease: A Marker of Severity and Prognosis

Chronic obstructive pulmonary disease (COPD) stands as one of the leading causes of mortality worldwide. Acute exacerbations of COPD (AECOPD) lead to rapid respiratory function decline and worsened disease status. Despite recent studies, the ability of the neutrophil-to-lymphocyte ratio (NLR) to predict outcomes in patients with COPD remains controversial. It remains controversial whether NLR can predict clinical outcomes in hospitalized patients with AECOPD. Therefore, this study was conducted to investigate the predictive value of NLR for severity, adverse outcomes in hospitalized patients with AECOPD, and predicting treatment response in patients with AECOPD

Read the detailed description

Chronic obstructive pulmonary disease (COPD) stands as one of the leading causes of mortality worldwide, posing an increasing economic burden. Acute exacerbations of COPD (AECOPD) are defined as acute deterioration of respiratory symptoms requiring additional treatment, leading to rapid respiratory function decline, diminished quality of life, and worsened disease status. Neutrophils are the most common type of white blood cells (WBC) and participate in multiple inflammatory and immune processes through phagocytosis and cytokine release. Lymphocytes play a crucial role as coordinators of the inflammatory and immune processes in various physiological mechanisms. The neutrophil-to-lymphocyte ratio (NLR) is calculated by dividing the number of neutrophils by the number of lymphocytes in the peripheral blood test, reflecting an increase in neutrophils and a secondary decrease in lymphocyte count during the inflammatory response. The NLR is considered a biological marker reflecting the inflammatory condition and is increasingly recognized in various disorders such as pneumonia, malignant, coronary artery disease, or hematological disorders.

    Neutrophil lymphocyte ratio in determining severity and prognosis in exacerbation of COPD patients

What is being measured

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

  1. The ratio of neutrophils to lymphocytes in (%) in the CBC

    investigate the relation between this % ratio and severity of symptoms and adverse hospitalization outcomes in hospitalized patients with AECOPD

    Measured: baseline

Secondary outcomes (1)
  1. The ratio of neutrophils to lymphocytes in (%) in the CBC

    • investigate the relation between this % ratio and spirometric indices (FEV1, FVC) as percent predicted in hospitalized patients with AECOPD in their follow up

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Obstructive Pulmonary Disease Exacerbation, run by Ain Shams University at 1 site in Egypt.

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 1 inclusion and 2 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: looking for participants now, as of the sponsor's last update on 15 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

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 Hieba G Ezzelregal, MD (01002041611, hiebagamal24@med.asu.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The ratio of neutrophils to lymphocytes in (%) in the CBC (time frame: baseline). 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 15 Aug 2025.
