Abstract
Context: Nelson's syndrome refers to aggressive pituitary corticotroph adenoma growth after bilateral adrenalectomy for treatment of Cushing's disease (CD). Pasireotide, a novel somatostatin analog, has been effective in treating CD. Here, the first case report of a patient with Nelson's syndrome treated with pasireotide is presented. Case Presentation: A 55-year-old female was diagnosed with CD in 1973 at age 15 years and underwent bilateral adrenalectomy 1 year later. She subsequently developed Nelson's syndrome and underwent multiple surgeries and radiotherapy for adenoma growth. After presentation with ocular pain, third cranial nerve palsy, and a finding of suprasellar tumor enlargement with hemorrhage, she began pasireotide long-acting release 60 mg/28 days im. At baseline, fasting plasma ACTH was 42 710 pg/mL (normal, 5-27 pg/mL), and fasting plasma glucose was 98 mg/dL. After 1 month, ACTH declined to 4272 pg/mL, and it has remained stable over 19 months of follow-up. Hyperpigmentation progressively improved. Magnetic resonance imaging scans show reduction in the suprasellar component. Fasting plasma glucose increased to 124 mg/dL, and the patient underwent diabetes management. Evidence Acquisition and Synthesis: In this clinical case seminar, the current understanding of the treatment of Nelson's syndrome and the use of pasireotide in CD are summarized. Conclusion: A case of Nelson's syndrome with clinically significant and dramatic biochemical and clinical responses to pasireotide administration is reported. Hyperglycemia was noted after pasireotide administration. Pasireotide may represent a useful tool in the medical management of Nelson's syndrome. Further study of the potential benefits and risks of pasireotide in this population is necessary.
