Cinacalcet and primary hyperparathyroidism: systematic review and meta regression

Area of Science:

• Endocrinology
• Metabolic Disorders
• Pharmacology

Background:

• Primary hyperparathyroidism (PHPT) is a prevalent endocrine disorder.
• Parathyroidectomy is the primary treatment for PHPT.
• The role of cinacalcet in PHPT management is not well-established.

Purpose of the Study:

• To evaluate the efficacy of cinacalcet in treating PHPT.
• To assess cinacalcet's impact on serum calcium and parathyroid hormone levels in PHPT patients.

Main Methods:

• Systematic literature search of Medline and Embase databases.
• Inclusion of prospective/retrospective cohorts and randomized controlled trials.
• Meta-analysis of continuous outcomes using weighted mean difference (WMD).

Main Results:

• Ninety percent of patients achieved normalized serum calcium levels.
• Significant reductions in serum calcium and PTH levels were observed.
• Phosphate levels significantly increased with cinacalcet therapy.

Conclusions:

• Cinacalcet demonstrates significant efficacy in reducing hypercalcemia in PHPT.
• The findings support cinacalcet as an alternative or bridging therapy for PHPT.
• Baseline calcium levels correlate with the degree of calcium reduction.
