ObjectiveTo determine effectiveness of technetium-99m labelled polyclonal human immunoglobulin G (99mTc-IgG) scintigraphy to monitor variation in arthritis activity in patients with rheumatoid arthritis (RA).MethodsThe results of semiquantitative 99mTc-IgG scintigraphy were compared with those of examination before and 26 weeks after initiation of parenteral gold treatment in 19 patients with RA.ResultsClinical and laboratory variables of arthritis activity as well as the scores of 99mTc-IgG scintigraphy were significantly lower after gold treatment compared to the scores before treatment. However, the difference between the mean scores of 99mTc-IgG scintigraphy before and after treatment was statistically significant for more joints than such difference in scores for joint pain and joint swelling.Conclusion99mTc-IgG scintigraphy is able to reflect variations in arthritis activity in patients with RA.
