Evaluation of rhGH Replacement Therapy in Patients With Pseudohypoparathyroidism Type Ia (PHP Ia)

Summary

We have recently demonstrated resistance to GHRH leading to GH deficiency in patients with Pseudohypoparathyroidism type Ia (Mantovani et al., J Clin Endocrinol Metab, 2003. 88: 4070-4074). The purpose of this study is to evaluate the effect of at least 1-year GH replacement in these patients. In particular, we will focus our attention on growth velocity in children affected with this disease.
