Abstract

Purpose: Data regarding the relationship between acromegaly and oxidative stress (OS) remain limited. Dynamic thiol-disulfide homeostasis (TDH) is vital for antioxidant protection, and ischemia-modified albumin (IMA) serves as a marker of OS. This study aimed to measure serum TDH parameters and IMA levels in acromegaly patients, comparing them with healthy controls.

Methods: This cross-sectional study consecutively included 81 patients and 55 controls, matched for age, gender, and body mass index. Serum levels of native thiol, total thiol, and disulfide (TDH parameters) were measured using the automated spectrophotometric method developed by Erel and Neselioglu, along with serum IMA levels.

Results: In patients, serum native and total thiol levels were significantly lower (p = 0.005 and p = 0.007), while serum IMA levels were significantly higher (p = 0.001). Disulfide levels were similar. Patients with active disease (N = 32), patients in remission (N = 49), and controls (N = 55) were compared. In post-hoc analyses; serum TDH parameters and IMA levels were similar in remission and active disease patients. Native and total thiol levels were significantly lower in patients in remission compared to controls (p = 0.01 and p = 0.04). IMA levels were significantly higher in patients in remission compared to controls (p = 0.04). Serum thiol levels positively correlated with serum insulin-like growth factor-1 levels and negatively with age and disease duration, while age independently exerted a negative impact on serum thiol levels.

Conclusion: Our findings may indicate increased OS in the acromegalic process, which may contribute to the development of acromegaly and its related complications and comorbidities.

期刊介绍： Pituitary is an international publication devoted to basic and clinical aspects of the pituitary gland. It is designed to publish original, high quality research in both basic and pituitary function as well as clinical pituitary disease. The journal considers: Biology of Pituitary Tumors Mechanisms of Pituitary Hormone Secretion Regulation of Pituitary Function Prospective Clinical Studies of Pituitary Disease Critical Basic and Clinical Reviews Pituitary is directed at basic investigators, physiologists, clinical adult and pediatric endocrinologists, neurosurgeons and reproductive endocrinologists interested in the broad field of the pituitary and its disorders. The Editorial Board has been drawn from international experts in basic and clinical endocrinology. The journal offers a rapid turnaround time for review of manuscripts, and the high standard of the journal is maintained by a selective peer-review process which aims to publish only the highest quality manuscripts. Pituitary will foster the publication of creative scholarship as it pertains to the pituitary and will provide a forum for basic scientists and clinicians to publish their high quality pituitary-related work.
