INTRAVENOUS REGIONAL ADMINISTRATION OF METHYLPREDNISOLONE IN RHEUMATOID-ARTHRITIS

Intravenous regional administration of corticosteroid (IVRAS) in the treatment of rheumatoid arthritis of the hand has not been reported previously. The method is based on a modification of Bier's block, with substitution of corticosteroid for local anaesthetic. Twenty-two patients were assessed in this double-blind, placebo-controlled study. The technique was safe and effective in improving grip strength, with a group mean improvement of more than 50%. Because suppression of endogenous cortisol production 24 h after treatment was commensurate with the dose of methylprednisolone used (40 mg), we could not exclude that the response may have been due to systemic steroid. Further studies are required to define the real value of IVRAS as it may offer alternative treatment of the joints and tendons within the hand and wrist in some patients rather than more prolonged oral therapy or individual, multiple joint or sheath injections.
