Coexistence of glucocorticoid resistance and pseudohypoparathyroidism

Abstract

We report for the first time the case of a young man who developed both glucocorticoid resistance and resistance to parathyroid hormone. Treatment with high doses of dexamethasone together with administration of calcium and calcitriol resulted in a significant improvement in the patient's condition. In this paper, we discuss in detail diagnostic and treatment strategies used on the patient and the impact on the course and outcome of both disorders. We associate the development of both these disorders with a possible inherited defect in the signal pathways common to glucocorticoid and parathyroid hormone receptors.
