PTH and Hypercalcemia: This ectopic production of calcitriol by the granulomas is either unregulated or is regulated by ways different from those controlling the normal renal production of this hormone.[33] Peces et al. reported that a successful management of TB resulted in resolution of hypercalcemia and an adequate parathyroid hormone response.[34] Any attempts at correction of hypercalcemia alone may prove detrimental to these patients.
