Subclinical high-resolution chest CT scan features in psoriasis.

Area of Science:

• Pulmonology
• Dermatology
• Radiology

Background:

• Psoriasis is a systemic inflammatory disease with unclear associations to lung conditions.
• Subclinical pulmonary involvement in psoriasis requires further investigation.

Purpose of the Study:

• To detect and characterize subclinical pulmonary abnormalities in psoriasis patients.
• To explore the relationship between cutaneous and pulmonary manifestations.

Main Methods:

• High-resolution computed tomography (HRCT) scans of the chest were used to screen adult psoriasis patients without active lung disease.
• Patients were categorized based on psoriasis severity, and clinical and radiographic data were analyzed.

Main Results:

• Nearly 80% of psoriasis patients exhibited abnormal HRCT findings.
• The most frequent findings included lung micronodules and nonspecific interstitial changes.
• Abnormalities correlated with older age and longer psoriasis duration, but not skin severity.

Conclusions:

• Psoriasis patients may present with subclinical lung alterations, such as micronodules and interstitial changes.
• These findings suggest a potential pulmonary involvement in the systemic nature of psoriasis.
• Larger multicenter studies are recommended to validate these preliminary results.
