Osteonecrosis of the hip after short courses of oral and inhaled steroids in a child with an increased number of glucocorticoid receptors

Abstract: We report an unusual case of osteonecrosis of the femoral head associated with recurrent myopathy and bone abnormalities in a two-year-old girl, in whom symptoms occurred after a ten-day course of oral betamethasone for infectious wheezy bronchitis, and eventually recurred and were worsened by topical treatment; a hypersensitivity to glucocorticoids is hypothesised.

“…In theory, the cumulative dose of inhaled steroid over a lifetime could add up to sizeable amounts. However, conclusions regarding steroid risk are again difficult to draw from the 4 reported cases related to inhaled steroids [14][15][16][17] because all cases were concurrently or subsequently treated with oral steroids prior to the diagnosis of osteonecrosis. Though no studies have been performed, the recent unapproved but commonplace use of swallowed ultra high dose inhaled steroids (specifically fluticasone dipropionate) to treat eosinophilic esophagitis will increase the risk of osteonecrosis in these patients.…”

“…However, the concurrence of them is rarely reported possibly due to overlook of either condition. Drigo I et al (7) described a child with increased number of GC receptors developed osteonecrosis and recurrent myopathy with steroid therapy. Here we reported concurrence of GC-induced osteonecrosis and pathologically confirmed myopathy in a patient with ABCB1 polymorphisms.…”

“…Other than the corticosteroid use, she had no known risk factors for the development of osteonecrosis. However, upon further testing she was found to have an increased number of glucocorticoid receptor sites per cell and thus an increased sensitivity to the medication [9]. …”
