What symptom improvement can be expected after operation for primary hyperparathyroidism?

Area of Science:

• Endocrinology
• Surgical Oncology
• Neurosurgery

Background:

• Primary hyperparathyroidism (pHPT) is typically cured by parathyroidectomy (PTx).
• Current National Institute of Health (NIH) guidelines for PTx may not identify all symptomatic pHPT patients.
• Subtle, nonspecific symptoms in pHPT are often overlooked or misattributed.

Purpose of the Study:

• To review evidence on symptoms associated with pHPT.
• To assess the impact of PTx on these symptoms.
• To inform recommendations for PTx indications.

Main Methods:

• Evidence-based literature review.
• Assessment of symptoms related to bone, neuropsychiatry, cognition, quality of life, and neuromuscular system.
• Assignment of evidence levels and recommendation grades.

Main Results:

• pHPT is linked to decreased bone density, increased fracture risk, neuropsychiatric and cognitive issues, reduced quality of life, and neuromuscular symptoms.
• Studies varied in quality regarding the effects of PTx on these symptoms.

Conclusions:

• Few Level I randomized clinical trials exist for PTx in pHPT.
• Supportive data suggest most pHPT patients benefit from surgical cure.
• Parathyroidectomy offers a potential cure for symptomatic pHPT.
