Arthritis: Reports from 2003 Arthritis Meeting (cont.)
British researchers found that Remicade infusions could be safely administered at faster rates after the first 4 infusions if no reactions were noted in the first infusions. They also noted that stopping and restarting Remicade as a treatment did not result in any increase in toxicity.
Dr. Shiel's Perspective: Exciting news for patients already using Remicade. It appears that they may not require the usual 2 hour rate of infusion after taking 4 doses of Remicade without side effects. Theoretically, Remicade might have the potential to cause sensitization. So that if Remicade were stopped and restarted at a much later date, there could be an increased chance of allergic reaction. However according to this research, if, for whatever reason, Remicade treatment is interrupted, resumption of the drug at a later time does not come with an increased chance for an infusion reaction!
Researchers from the United Kingdom reported that patients whose rheumatoid arthritis is not controlled with Remicade can respond successfully to Enbrel.
Dr. Shiel's Perspective: Well, this is very interesting. Since both Remicade and Enbrel block TNF as a key method of action, one might expect that switching from one drug to the other might not be effective. Wrong. The researchers point out that the reason for the benefit from switching might be related to the fact that they do differ slightly in their targets (Remicade binds to both a soluble form of TNF-alpha and to TNF-alpha bound to membranes of cells, while Enbrel binds to soluble TNF-alpha and to another chemical messenger lymphotoxin-alpha). Big words! They simply mean that if one fails on one TNF-blocking drug, it is rational to try another.
Dr. Shiel's Perspective: Actually, rheumatologist have been using the drug for these patients for some time because of other preliminary positive reports in these conditions. It is good to have the support of this further long-term follow-up research.
Remicade was effective in treating sarcoidosis of the lungs and its accompanying toxic levels of calcium.
Dr. Shiel's Perspective: Other reports of Remicade treatment of sarcoidosis are supported by this report. Remicade seems to have beneficial effects in many diseases that feature microscopic areas of tissue inflammation called granulomas. These diseases include Crohn's disease, Wegener's granulomatosis, and sarcoidosis.
Remicade was also reported to be effective in juvenile ankylosing spondylitis.
Dr. Shiel's Perspective: Welcome news for this painful form of arthritis in children.
