Abstract
Background
Pituitary adenomas are benign tumors located in the anterior hypophysis. Its appearance is associated with the development of parameters related to metabolic syndrome; therefore, surgical treatment could reduce associated morbimortality.
Methods
Pre- and post-surgical MRI, using the Hardy–Wilson and Knosp classification, and clinical data according to the American Association of Clinical Endocrinology (AACE) criteria for metabolic syndrome: all the patients were followed-up until 208.57 days were reviewed on 217 consecutive patients with pituitary surgery.
Results
Seventy-four patients were included in this study. There was a significant reduction in tumor size in mm3 [average pre- and post-surgery respectively: 12,362 mm3 (±12,397); 3,910 mm3 (±7,160)], (p < 0.0001). This was confirmed by the Hardy–Wilson and Knosp classification, where most patients went from grade IV C (33.7%) to grade 0 (12.1%), IA (20.2%), IIB (21.36%), and IIC (16.2%); as well as from grade 4 (24.3%) to grade 0 (45.9%), respectively. After surgery, there were statistically significant reductions in total serum levels of glucose [average pre- and post-surgery, respectively: 116 mg/dL (±26.9); 90 mg/dL (±10.2)], (p < 0.001), triglycerides [average pre- and post-surgery, 240 mg/dL (±102); 171 mg/dL (±60.5)], (p = 0.001); and HDL-c [average pre- and post-surgery, respectively: 39 mg/dL (±11.8); 44.6 mg/dL (±8.4)], (p = 0.029). The other parameters remained unchanged.
Conclusion
This is the first study to demonstrate the relationship between the presence of pituitary adenoma and significative changes in serum glucose, triglycerides and c-HDL related to metabolic syndrome.
