Effect of curative parathyroidectomy on insulin resistance

Background: Primary hyperparathyroidism (PHPT) is characterized by inappropriately elevated serum parathyroid hormone (PTH) level despite elevated serum calcium. Insulin resistant is the basic pathophysiology, behind the higher prevalence of diabetes mellitus in patients with PHPT. However, the impr...

description Background: Primary hyperparathyroidism (PHPT) is characterized by inappropriately elevated serum parathyroid hormone (PTH) level despite elevated serum calcium. Insulin resistant is the basic pathophysiology, behind the higher prevalence of diabetes mellitus in patients with PHPT. However, the improvement in insulin resistance (IR) after curative parathyroidectomy (CPTX) has not been established yet, as the study results are conflicting. Materials and Methods: In this prospective interventional study, ten patients with mild PHPT (Group 1) and another ten patients with moderate to severe PHPT (Group 2) were undergone CPTX. The IR was assessed by homeostasis model assessment-IR (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), fasting plasma glucose (FPG), and fasting serum insulin (FSI), before and 3 months after CPTX. Results: There was no significant change of FPG and FSI, before and after CPTX in Group 1 (P = 0.179 and P = 0.104) and Group 2 (P = 0.376 and P = 0.488). Before surgery, HOMA-IR was higher, and QUICKI was significantly lower, in both Group 1 (P = 0.058 and P = 0.009) and Group 2 (P = 0.023 and P = 0.005) as compared to published normal reference mean, with no significant difference between the groups. Three months after surgery HOMA-IR increased further and QUICKI remained unchanged as compared to baseline, in both Group 1 (P = 0.072 and 0.082) and Group 2 (P = 0.54 and 0.56), but statistically insignificant. Conclusion: IR remained unchanged after CPTX in mild as well as moderate to severe PHPT. Asymptomatic PHPT with abnormal IR should not be used as criteria for parathyroidectomy.
