Extrapulmonary involvement in patients with sarcoidosis in Turkey

Area of Science:

• Pulmonology
• Rheumatology
• Dermatology

Background:

• Extrapulmonary sarcoidosis is frequently observed alongside thoracic involvement.
• Manifestations of extrapulmonary sarcoidosis can differ based on demographic factors like gender, age, and ethnicity.
• Understanding these variations is crucial for comprehensive patient care.

Purpose of the Study:

• To investigate the prevalence and characteristics of extrapulmonary involvement in sarcoidosis patients within Turkey.
• To identify common sites of extrapulmonary disease and associated demographic factors.

Main Methods:

• A multicenter study involving new sarcoidosis cases recorded between June 2004 and May 2006.
• Data collection utilized electronic case record forms to gather information on extrapulmonary manifestations.
• The Turkish Thoracic Society Clinical Problems Study Group coordinated the data collection.

Main Results:

• 40.6% of 293 sarcoidosis patients exhibited extrapulmonary involvement.
• The most common symptoms were skin lesions (33.4%), arthralgia (20.8%), and back pain (16.4%).
• Ocular involvement was significantly higher in patients younger than 40 years (P = 0.007).

Conclusions:

• Skin and peripheral lymph node involvement are the predominant sites of extrapulmonary sarcoidosis in the Turkish population.
• Ocular sarcoidosis demonstrates a higher incidence in younger patients (under 40).
• These findings highlight the importance of considering specific extrapulmonary sites based on patient demographics.
