Background
The only cure for primary hyperparathyroidism (pHPT) is operative resection of the parathyroid gland(s) responsible for the disease. The 1990 National Institute of Health’s (NIH) consensus development conference on asymptomatic pHPT and its subsequent workshop in 2001 established which clinical criteria warranted parathyroidectomy (PTx) versus observation. While there is no debate that these NIH criteria capture a group of patients likely to benefit from PTx, there is concern that these guidelines miss a significant percentage of pHPT patients who actually are symptomatic. Unfortunately, these additional symptoms are often subtle, nonspecific, not traditionally measured, frequently not assessed or considered in this patient population, and are usually attributed to other diagnoses or simply advanced age.
Methods
An evidence-based literature review was performed assessing symptoms and clinical conditions associated with bone, neuropsychiatry, cognition, quality of life, and the neuromuscular system. The level of evidence and grade of recommendations were assigned to key studies to help determine recommendations regarding indications and potential benefits of parathyroidectomy (PTx).
Results
Symptoms ranging from decreased bone mineral density, increased fracture risk, neuropsychiatric symptoms and cognitive changes, lower quality of life, and neuromuscular symptoms were found to be associated with pHPT. The effects of PTx on these symptoms was addressed in a variety of studies that varied in quality.
Conclusion
Although there are few Level I randomized clinical trials addressing the benefit of PTx in patients with pHPT, there are supportive data to suggest that most patients with pHPT would benefit from operative cure.
