The usual Interstitial pneumonia pattern in autoimmune rheumatic diseases

Area of Science:

• Pulmonology
• Rheumatology
• Radiology
• Pathology

Background:

• Usual Interstitial Pneumonia (UIP) pattern is observed in autoimmune rheumatic diseases (ARDs).
• UIP in ARDs can present with specific imaging (e.g., "straight-edge" sign) and histologic features, distinguishing it from Idiopathic Pulmonary Fibrosis (IPF).
• Systemic involvement and comorbidities in ARDs impact functional evaluation and patient outcomes.

Purpose of the Study:

• To review the definition, radiological, and morphological features of UIP in ARDs.
• To outline risk factors, diagnostic criteria, prognostic evaluation, and management strategies for UIP in ARDs.
• To discuss the multidisciplinary approach for diagnosis, severity assessment, and treatment response in UIP-ARDs.

Main Methods:

• Review of literature on UIP in the context of ARDs.
• Analysis of diagnostic features, including HRCT and histology.
• Discussion of multidisciplinary team's role in diagnosis and management.

Main Results:

• UIP in ARDs exhibits distinct features from IPF, aiding differential diagnosis.
• Multidisciplinary diagnosis (MDD) is crucial for evaluating severity, progression, and treatment response.
• Treatment involves balancing systemic and lung disease control with comorbidity management.

Conclusions:

• Accurate diagnosis of UIP in ARDs requires a multidisciplinary approach.
• Management strategies must consider systemic disease, comorbidities, and therapeutic risks.
• Further evidence is needed for optimal pharmacological treatment of UIP in ARDs.
