Relationship between thyroid nodule, prolactin, and thyroid peroxidase antibody levels: A case-control study

Area of Science:

• Endocrinology
• Oncology

Background:

• Thyroid nodules are a clinical concern due to potential malignancy.
• Elevated prolactin, a mitogen, may contribute to cancer.
• Thyroid peroxidase antibody (TPO-Ab) is linked to thyroid nodularity in hyperprolactinemia.

Purpose of the Study:

• Investigate the relationship between serum prolactin, thyroid nodularity, and TPO-Ab presence.
• Analyze correlations between thyroid nodules and specific biomarkers.
• Determine if TPO-Ab status influences nodule characteristics.

Main Methods:

• Ninety patients were divided into control, TPO-Ab positive, and TPO-Ab negative nodule groups.
• Serum prolactin, TPO-Ab, TSH, T4, and ultrasound data were analyzed.
• Statistical significance was determined using p < 0.05.

Main Results:

• Serum TSH, prolactin, and TPO-Ab levels were significantly higher in patients with thyroid nodules.
• Hyperprolactinemia was more prevalent in the nodule group (35% vs. 13.3%).
• TPO-Ab positive nodules showed greater solidity compared to TPO-Ab negative nodules.

Conclusions:

• Thyroid nodules correlate positively with increased serum TSH, prolactin, and TPO-Ab.
• TPO-Ab positive nodules exhibit greater solidity and elevated TSH levels.
• These findings highlight potential links between hormonal factors and thyroid nodule characteristics.
