[Changes in the lungs in diabetes mellitus]

Area of Science:

• Pathology
• Pulmonology
• Endocrinology

Context:

• Diabetes mellitus is a systemic disease with significant pulmonary manifestations.
• Autopsy studies provide crucial insights into the long-term effects of diabetes on organ systems.

Purpose:

• To investigate the morphological changes in the lungs of patients with varying degrees of diabetes mellitus.
• To identify the specific vascular and parenchymal alterations in the diabetic lung.

Summary:

• Diabetic microangiopathy affects lung capillaries, arterioles, and pleural vessels, causing plasmorrhagia, basal membrane thickening, and hyalinosis.
• Intraseptal nodules, granulomas, focal proteinosis, microcirculatory sclerosis, and centrilobular emphysema are observed.
• These pathological changes create a predisposition to pneumonia and pulmonary-cardiac insufficiency, common causes of death.

Impact:

• Highlights the critical role of pulmonary complications in diabetes mellitus mortality.
• Underscores the need for pulmonary monitoring in diabetic patients.
• Provides a basis for understanding the pathogenesis of diabetic lung disease.
