Mild primary hyperparathyroidism: a literature review

Area of Science:

• Endocrinology
• Metabolic Disorders
• Surgical Oncology

Background:

• Classic primary hyperparathyroidism (pHPT) is defined by elevated calcium and parathyroid hormone (PTH) levels.
• Parathyroidectomy is the standard treatment for pHPT, unless medically contraindicated.
• Mild pHPT, characterized by isolated elevated calcium or PTH, is increasingly detected through routine screenings.

Purpose of the Study:

• To review literature on mild pHPT.
• To characterize patients with mild pHPT.
• To determine the benefits of parathyroidectomy for mild pHPT.

Main Methods:

• Literature review of studies on mild primary hyperparathyroidism.
• Analysis of patient populations with mild pHPT.
• Evaluation of outcomes following parathyroidectomy in mild pHPT cases.

Main Results:

• Some patients with mild pHPT experience symptom improvement after parathyroidectomy.
• A subset of mild pHPT patients progress to classic pHPT over time, unpredictably.
• Parathyroidectomy is safe in carefully selected patients at high-volume centers.

Conclusions:

• Early intervention with parathyroidectomy may prevent bone, psychiatric, and renal complications in mild pHPT.
• Identifying patients who will progress from mild to classic pHPT remains a challenge.
• Parathyroidectomy can be a safe and effective option for select mild pHPT patients.
