8539 Curcumin a Double Edged Sword: A Case of Curcumin Induced Pituitary Macroadenoma Apoplexy

Abstract Disclosure: P. Balozian: None. D. Alfakara: None. M. Linz: None. <Curcumin, the active component of turmeric, exerts numerous beneficial anti-inflammatory, antiplatelet, and anticoagulant effects. Recent literature has shown however that curcumin inhibits proliferation and induces apoptosis of pituitary cells. Despite these findings, there are limited clinical cases reporting an association between curcumin and pituitary adenoma apoplexy.We report the case of a 39-year old G9P6A3 female with Hashimoto’s disease and class II obesity who presented with a constant bifrontal excruciating headache, blurry vision, photophobia, and nausea. She also had fatigue and amenorrhea for two years. Her exam showed normal vitals, decreased visual acuity, diplopia, and bitemporal hemianopsia. Data showed a serum prolactin of 69 ug/L , plasma IGF-1 of 133 ng/ml (Z score -0.4), TSH of 2.58 with a free T4 of 0.47 ng/dl [0.61-1.12 ng/dL], a random cortisol of 12.7 mcg/dl despite her stress and pain, ACTH of 27 pg/ml, DHEA-S of 46 mcg/dl, an LH of 0.5 IU/L, and an FSH of 4mIU/ml with an estradiol of 25 pg/ml. MRI of the pituitary revealed a 1.8 cm macroadenoma with a mass effect on the overlying optic chiasm and a T1 intrinsic hyperintense signal indicative of a hemorrhagic component. She was given IV dexamethasone for 24 hours then underwent transsphenoidal resection of the hemorrhagic tumor that resulted in rapid resolution of headaches and visual symptoms. She was not given any glucocorticoids during or after surgery. Labs immediately after surgery revealed a prolactin of <1ug/L and a cortisol of 26.7 mcg/dl. Pathology showed corticotroph tumor with hemosiderin deposition with a 4.2% Ki67 and negative ACTH immunostaining. On medication review, patient had been taking large doses of curcumin. In the absence of other recent precipitating factors, it was highly likely that she had curcumin-triggered apoplexy of a pituitary macroadenoma. Most recent bloodwork, about 20 months from presentation, revealed a serum prolactin of 5.0 ug/L, IGF-1 of 123ng/mL (Z score -0.6), TSH of 0.97 mIU/L with a free T4 of 0.85 ng/dL, a random cortisol of 5.3 ug/dL, ACTH of 18.2 pg/mL, DHEA-S of 94 ug/dL, LH of 2.5 IU/L, FSH of 4.3 IU/L, and an estradiol of 45 pg/mL. Regular menstrual cycles had resumed. Headaches, nausea, and vision abnormalities completely resolved.The case illustrates the need to identify any herbal remedies and supplements a patient is taking, particularly turmeric, as supplements may contribute to increased bleeding tendency of an already existing adenoma. The case also emphasizes the potential rapid recovery of pituitary function after surgical resection of an apoplectic pituitary tumor.> Presentation: 6/3/2024
