Serum levels of IgA, IgM, IgD and IgE in IgG paraproteinaemias.
The dependence of serum levels of polyclonal IgA, IgM, IgD and IgE on the amount of IgG paraprotein was studied in a series of 58 IgG paraproteinaemias. A significant correlation was found for IgA (r = -0.4782, p = 0.0007), for IgM (r = -0.3296, p = 0.0237) and for IgD (r = -0.3589, p = 0.0143) in the whole series of IgG paraproteinaemias and in the subgroup of myeloma paraproteinaemias (n = 34) for IgM (r = -0.4276, p = 0.0207) and for IgD (r = -0.4384, p = 0.0196).
