Abstract

IgG antibodies to monophosphoryl lipid A (MPL) are more concentrated in synovial fluids than in the blood of children with pauciarticular juvenile arthritis. Correlations between IgG anti-MPL levels and numbers of inflamed joints were highly significant in 2 of 10 patients followed for 8 years and suggestive in 2 patients followed for shorter periods. A fifth patient had a correlation between IgM anti-MPL and joint count.
