[Lymphocyte membrane markers in monoclonal gammopathies].

The distribution of peripheral blood lymphocytes with immunoglobulins (Ig) in 14 patients with monclonal gammapathies has been studied. The patients have been divided in two groups, one including patients never treated, the other those studied during or after treatment. The results, compared with 11 control subjects, show that lymphocytes with surface Ig from the same class of the serum paraprotein increased in every case of the first group and in some cases of the second.
