Hashimoto's thyroiditis-induced cryptogenic organizing pneumonia: A case report

Area of Science:

• Pulmonology and Endocrinology
• Autoimmune diseases and respiratory conditions

Background:

• Cryptogenic organizing pneumonia (COP) is an idiopathic interstitial pneumonia.
• Hashimoto's thyroiditis (HT) is a common autoimmune endocrine disorder.
• The co-occurrence of COP and HT is infrequently reported, suggesting a potential link.

Purpose of the Study:

• To report a case of a patient presenting with symptoms suggestive of pulmonary infection.
• To investigate the association between respiratory symptoms and autoimmune thyroid disease.
• To explore the potential causal relationship between Hashimoto's thyroiditis and cryptogenic organizing pneumonia.

Main Methods:

• Clinical presentation and initial investigations including chest radiography and CT scan.
• Diagnostic procedures: Bronchoscopy with biopsy for lung tissue analysis.
• Endocrine evaluation: Thyroid ultrasound and thyroid function tests.

Main Results:

• Initial treatment for presumed pulmonary infection was ineffective.
• Histopathological examination confirmed cryptogenic organizing pneumonia (COP).
• Concurrent diagnosis of Hashimoto's thyroiditis (HT) was established.
• Patient showed significant improvement following corticosteroid therapy.

Conclusions:

• Cryptogenic organizing pneumonia (COP) can co-exist with Hashimoto's thyroiditis (HT).
• Hashimoto's thyroiditis (HT) may be implicated in the pathogenesis of COP.
• Prompt diagnosis and management, including corticosteroids, are crucial for favorable outcomes.
