The development of systemic sclerosis in a female patient with multiple sclerosis following beta interferon treatment.

ABSTRACT

We describe a 38-year-old patient with relapsing remitting multiple sclerosis who subsequently develops systemic sclerosis following a course of interferon B-1a injections. This rare association between MS and systemic sclerosis is interesting due to the added factor of beta interferon therapy prior to the onset of the systemic sclerosis. It is also important, as more patients are treated with interferon B-1a for multiple sclerosis, this is a potential association.
