| Abstract: | The relationship between quantitative splenic uptake of sulfur colloid and immunoglobulin M level in serum was studied in 15 patients with systemic lupus erythematosus (SLE). Splenic function correlated positively with IgM level (r = 0.58, p = 0.02) and inversely with antibody titre to n-DNA (r = -0.74, p = 0.003), and was reduced (p greater than 0.001) in patients with depressed IgM levels. IgM level in serum may be a useful correlate of splenic phagocytic function in SLE patients. |
