Background:
Understanding the relationship between psoriasis and chronic obstructive pulmonary disease (COPD) may enhance disease management.
Objectives:
We aimed to determine the (1) prevalence and (2) incidence and risk of COPD in psoriasis patients.
Results:
The COPD prevalence was 9.64 % in psoriasis patients and 6.94 % in psoriasis-free patients. The COPD incidence was 10.74 per 1000 person-years in psoriasis patients and 6.36 per 1000 person-years in psoriasis-free patients. Multivariable Cox regression showed no association between psoriasis and COPD development (HR 0.99, p = 0.271).
Conclusions:
Our findings suggest that psoriasis is not an independent risk factor for COPD development.

Chronic Obstructive Pulmonary Disease-I: Introduction
Chronic Obstructive Pulmonary Disease
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-III: Symptoms and Complications.
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.
