INTRODUCTION: Serum cortisol levels within the first days after pituitary surgery have been shown to be a predictor of post-surgical adrenal insufficiency. However, the indication of empirical glucocorticoids to avoid this complication remains controversial. The objective is to assess the role of cortisol in the early postoperative period as a predictor of long-term corticotropic function according to the pituitary perisurgical protocol with corticosteroid replacement followed in our center.
METHODS: One hundred eighteen patients who underwent surgery in a single center between December 2012 and January 2020 for a pituitary adenoma were included. Of these, 54 patients with previous adrenal insufficiency (AI), Cushing's disease, or tumors that required treatment with high-dose glucocorticoids (GC) were excluded. A treatment protocol with glucocorticoids was established, consisting of its empirical administration at rapidly decreasing doses, and serum cortisol was determined on the third day after surgery. Subsequent adrenal status was assessed through follow-up biochemical and clinical evaluations.
RESULTS: Out of the 64 patients treated, there were 56 macroadenomas and 8 microadenomas. The incidence of adrenal insufficiency after pituitary surgery was 4.7%. The optimal cut-off value that predicted an adequate corticotropic reserve, taking into account the best relationship of specificity and sensitivity, was ≥4.1 μg/dl for serum cortisol on the third day (sensitivity 95.1%, specificity 100%).
CONCLUSION: Serum cortisol on the third day predicts the development of adrenal insufficiency. We suggest a cortisol cut-off point of ≥4.1 μg/dl on postoperative on the third day after surgery as a predictor of the adrenal reserve in the long-term.
