There was for female relatives a highly significant negative correlation between NK cell numbers and IgM ( r = −0.54, p < 0.005) and a weaker negative correlation between B cells and IgM (−0.40, p < 0.05).
There was for female relatives a highly significant negative correlation between NK cell numbers and IgM ( r = −0.54, p < 0.005) and a weaker negative correlation between B cells and IgM (−0.40, p < 0.05).
There was a strong negative correlation with NKT cell numbers in the male relative group (−0.69, p < 0.01) while a similar relationship in the female relatives approached significance (−0.34, p < 0.08).
It may be significant that reduced levels of the regulatory cytokines TGF-β and IL-10 have been observed in relatives. 13 In the study by Wither et al. 12 abnormalities were demonstrated in first-degree relatives of SLE patients relating to the proportion of various B and T cell subsets and in the frequency of antinuclear antibody (ANA) positivity.
