Abstract

Background:

The effect of association between chronic obstructive pulmonary disease (COPD) and diabetes (DM) on platelet function has not been studied before.

Objectives:

To evaluate the effect of the association between COPD and DM on platelet function and C reactive protein (CRP).

Patients And Methods:

This case control study was carried out on 110 stable COPD patients who were classified into diabetic and nondiabetic groups. In addition, 40 apparently healthy, age and sex-matched individuals were included in this study as a control group. Chest X-ray, pulmonary function testing and arterial blood gases were done for COPD patients. CRP and complete blood count (CBC) were measured in both patient and control groups.

Results:

Mean platelet volume (MPV), platelet distribution width (PDW), platelet crit (PCT) and CRP were significantly higher in COPD patients either nondiabetic or diabetic compared to control group. Moreover, MPV and CRP markers were significantly higher in COPD diabetic patients compared to nondiabetic. There was no significant difference in various laboratory data among different stages of COPD either diabetic or nondiabetic (P > 0.05). In COPD patients, MPV was a significantly positively correlated with CRP and PDW (r = 0.346, P < 0.001; r = 0.510, P < 0.001, respectively) and negatively correlated with PLT count (r = -0.294, P = 0.002).

Conclusion:

MPV, PDW, PCT and CRP were significantly higher in COPD patients either nondiabetic or diabetic. Platelet function may be modified by the systemic inflammation that associated with COPD. Platelet activation as a prothrombotic sequence of this disease may be used as novel therapeutic target.

Chronic Obstructive Pulmonary Disease-II: Pathophysiology

Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:
Chronic Inflammation

Chronic Obstructive Pulmonary Disease

Chronic Obstructive Pulmonary Disease

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Chronic Obstructive Pulmonary Disease-I: Introduction

Chronic Obstructive Pulmonary Disease-I: Introduction

Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Chronic Obstructive Pulmonary Disease-IV: Assessement and Diagnostic Studies

Assessing and diagnosing Chronic Obstructive Pulmonary Disease (COPD) involves a detailed approach that includes a comprehensive review of medical history, physical examination, and a variety of diagnostic tests. This thorough evaluation is essential to ensure an accurate diagnosis and guide effective management strategies.

Chronic Obstructive Pulmonary Disease-V: Management

Managing Chronic Obstructive Pulmonary Disease (COPD) involves a multifaceted approach to reduce symptoms, prevent exacerbations, improve overall health status, and slow disease progression. Key strategies include lifestyle modifications, pharmacotherapy, supportive therapies, and, in some cases, surgery. Here is an overview of the primary COPD management strategies:

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
