Acromegaly by Dr. B. Kamanga - Clinical Features, Diagnosis and Management of GH-Secreting Adenomas

Description

This comprehensive lecture on acromegaly, authored by Dr. B. Kamanga, provides an authoritative overview of this rare endocrine disorder caused by excessive growth hormone secretion, typically from a pituitary adenoma. The presentation details the pathophysiology, including the roles of growth hormone-releasing hormone and somatostatin, and covers the characteristic clinical manifestations such as acral enlargement, soft tissue growth, cardiovascular complications like hypertension and cardiomyopathy, respiratory issues including sleep apnea, and metabolic disturbances such as insulin resistance and diabetes mellitus. It outlines the diagnostic criteria, emphasizing the failure of GH suppression during an oral glucose tolerance test and the evaluation of age-adjusted IGF-1 levels. The lecture thoroughly reviews the management strategies, which include transsphenoidal surgery as the primary treatment for well-circumscribed tumors, medical therapies like somatostatin receptor ligands and the GH receptor antagonist pegvisomant, and the role of radiotherapy as a third-line option. This resource is essential for medical students, postgraduate trainees in endocrinology and internal medicine, and practicing clinicians seeking to deepen their understanding of the clinical evaluation, complex multi-system involvement, and evidence-based therapeutic approaches for acromegaly. It serves as a valuable study and revision tool for mastering this challenging pituitary disorder. Review this detailed presentation to enhance your clinical knowledge and diagnostic acumen.
