title: Effects of intravenous regional administration of methylprednisolone plus mepivacaine in rheumatoid arthritis.
abstract: To evaluate the subjective and objective response to intravenous regional administration of a glucocorticoid (IVRAG) on rheumatoid arthritis (RA), twenty RA-patients received, in a randomised, double-blind crossover and placebo-controlled fashion, either 50 mg methylprednisolone in mepivacaine 0.25% or mepivacaine (placebo) in one hand only using a Bier-block technique. The other hand was given the opposite. One week later the procedure was repeated but the previous placebo hand was now treated with the glucocorticoid. About 50% of the patients experienced a subjective improvement at 1 and 6 weeks. After one week a significant reduction was recorded in grip diastasis with no difference between the glucocorticoid and the placebo. In the other outcome measures (grip strength, handvolume, rest pain, and movement provoked pain) no differences were recorded between the glucocorticoid and placebo. At six weeks a significant reduction in grip diastasis and movement provoked pain as well as a significant increase in grip strength were noted. Hand volume was unchanged. IVRAG is a safe, easy and well-tolerated technique. The beneficial results are probably due to both a systemic and a regional effect. The findings of benefit in both hands at the end of one week seem to suggest that mepivacaine can give some short term improvement.
