A rare, chronic disease caused by excessive secretion of growth hormone (GH), usually due to a pituitary somatotroph adenoma. It is associated with increased morbidity and premature mortality.
The diagnosis is often delayed. Early recognition and appropriate treatment are crucial for reducing the potentially debilitating complications of the disease.
Must be screened for in the presence of acral growth, coarsening of facial features, and when suspected in conjunction with commonly associated conditions, such as carpal tunnel syndrome, arthralgia, glucose intolerance or diabetes, amenorrhea, HTN, and sleep apnea.
Modern surgical and pharmacologic modalities are associated with improved outcomes. While the overall mortality ratio remains increased (1.6-fold compared with the general population), normalization of plasma insulin-like growth factor 1 (IGF-1) and a decrease of plasma GH to below 1 microgram/L bring the mortality rate to normal.
Monitoring and treatment of the comorbidities associated with acromegaly are essential for improving the quality of life of patients.
The term acromegaly is derived from the Greek akros (meaning extremity) and megas (large). It refers to the characteristic growth of extremities, which describes one aspect of the disease. Acromegaly is a chronic, progressive, multisystemic disease associated with significant morbidity and increased mortality. It is caused by excessive secretion of growth hormone, usually due to a pituitary somatotroph adenoma. Gigantism occurs with disease onset in childhood (prior to epiphyseal closure).
