On Golimumab For Psoriatic Arthritis. High Gamma GT Reading And High BP. What Is Causing This?
Many thanks,
Thank you for writing to us.
As you know, Golimumab is a humanized anti-TNF agent and approved for psoriatic arthritis.
It also helps in lowering the dose of steroids.
Phase II and III trials had shown that golimumab leads to a mild increase in ALT and AST and very high levels (>5 times upper limit) was rare. The raised GGT in your case may mean something similar but it is not very high (you should check what the upper limit of normal GGT is from the lab). You have not mentioned the AST and ALT levels. If those, along with alkaline phosphatase, white cell count, CRP is normal or just mildly raised, then the GGT is not very significant. Also GGT is quite sensitive, hence most Rheumatologists would check the AST and ALT levels.
You are right in saying that steroids may be affecting the GGT and the blood pressure. Your previous BP was quite low and the new one is more acceptable, although I get your point. You should check with your doctor on the possibility of changing over to Deflazacort from Prednisolone as it has much lower side effects.
You must give the Golimumab a chance and please do not hesitate to ask if you have any more queries.
Best Wishes.
