[Cold lymphocytotoxins in various pathological situations]

Cold lymphocytotoxins have been described extensively in many situations. In the present work, this kind of antibody has been found less frequently than previously in some diseases like infectious mononucleosis, rheumatoïd arthritis, or kidney transplanted patients. These discrepancies may be due to technical considerations. In contrast, cold lymphocytotoxins, in the present work, have been frequently detected in auto-immune hemolytic anemias with cold agglutinins, and in patients having immuno-deficiencies.
