Fracture risk not associated with vitamin A analogue treatment

The aim of this case-control study was to study fracture risk associated with use of systemic vitamin A analogue (isotretinoin and acitretin) treatment involving a total of 124,655 patients with fractures (cases) and 373,962 age- and sex-matched controls.

No trend in risk of any fracture or of hip, forearm, or spine fractures was present with increasing doses or durations of treatment with vitamin A analogues. Subdividing vitamin A analogues into isotretinoin and acitretin did not change the results.

The researchers concluded: "Risk of fracture is not associated with vitamin A analogue treatment."

This is reassuring, but may require longer term follow up.
