A Study on the Values of Static and Dynamic Biological Tests Used in the Diagnosis of Hypersomatotropinism and Its Complications

Abstract

The role of routine, classic, and modern diagnostic tests in the diagnosis of active hypersomatotropinism was investigated by examining 80 cases of acromegaly. Phosphoremia and diurnal variations in phosphorus levels did not provide significant information for diagnosis or for the determination of disease activity. The examination of basal somatotropin (STH) levels was found to be useful in determining activity, except in 7.5% of the cases. It became apparent that at least two basal STH determinations in each case are essential for diagnosis. In cases of 'forme fruste' or inactive acromegaly, and for monitoring the effectiveness of treatment in previously treated patients, early diagnosis is only possible through the dynamic study of STH secretion. In this regard, the determination of autonomous STH secretion via insulin stimulation and glucose suppression tests is the most significant evidence for disease activity. In contrast, demonstrating the stimulability and suppressibility of this secretion serves as the most crucial evidence for treatment effectiveness.
