Does 25-hydroxyvitamin D status affect intraoperative parathyroid hormone dynamics in patients with primary hyperparathyroidism?
Lower 25OHD levels are correlated with higher PTH and alkaline phosphatase levels in patients with primary hyperparathyroidism. 25OHD status did not affect the average percent ioPTH decrease or the rate of cure. 25OHD deficiency does not affect ioPTH dynamics.
Male gender and coexisting COPD were shown to be independent predictors of non-response to CRT in this cohort of patients fulfilling current criteria for CRT.
