Matrix metalloproteinases (MMPs) are believed to play a role in the pathogenesis of multiple sclerosis (MS).

As methylprednisolone is the treatment of choice for a relapse, we investigated the effect of methylprednisolone on blood levels of MMPs.

Baseline TIMP-1 and MMP-2 levels were lower in MS patients than in healthy controls.

MMP-9 levels tended to be elevated.

During therapy, MMP-9 levels demonstrate a dose-dependent increase.

No effect was noted on TIMP-1 and MMP-2 levels.

The short-lived increase of MMP-9 plasma levels may be at least in part due to an activation and an increase of granulocytes and monocytes by methylprednisolone.
