    Description / Table of Contents: Summary Peripheral blood lymphocytes from 32 patients with defined paraproteinaemia (16 IgG, 9 IgA and 7 IgM) and from 15 healthy donors were studied for their in vitro response to various stimuli, including unspecific mitogens such asPhytohaemagglutinin (PHA),Pokeweedmitogen (PWM) and Concanavalin A (ConA) as well as specific antigens such as purified Tuberculin, Candida, Varidase, Tetanus Toxoid, Vaccinia antigen and Vaccinia-control antigen. Mitogens and antigens were lyophilized in Microtiter plates. The lymphocytes of all tested patient-groups responded (measured by H3-Thymidin-up-take) significantly lower towards the unspecific mitogens than those of the control group. If the patients' lymphocytes were stimulated by the specific antigens, their in vitro response was significantly diminished to candida and vaccinia. Macroglobulinaemia showed significantly lower response to ConA if compared to myelomas of IgG- and IgA-type. No correlation was found between mitogen and antigen response and the serum concentration of the paraproteins or immunoglobulins. The results show that monoclonal gammopathy and especially macroglobulinaemia are associated with abnormalities of the cellular immunity which correlates with the clinical observation of increased fungal and viral infections.
    Notes: Zusammenfassung Periphere Lymphozyten von 32 Patienten mit monoclonaler Gammopathie (16 IgG, 9 IgA and 7 IgM) und von 15 gesunden Spendern wurden hinsichtlich ihrer in vitro-Antwort auf folgende Stimuli untersucht: unspezifische Mitogene wiePhytohämagglutinin (PHA),PokeweedMitogen (PWM) andConcanavalinA (COnA), sowie die spezifischen Antigene Tuberkulin, Candida, Varidase, Tetanus Toxoid, Vaccinia-Antigen and Vaccinia-Kontroll-Antigen. Mitogene und Antigene wurden in lyophilisierter Form in Microtiter-Platten benützt. Die Lymphozyten aller getesteten Patienten-Gruppen antworteten signifikant niedriger auf Mitogenstimulation (gemessen am H3-Thymidin-Einbau) als diejenigen der Kontrollgruppe. Wenn die Patientenlymphozyten mit spezifischen Antigenen stimuliert wurden, ergab sich eine signifikant erniedrigte Antwort auf Candida- und Vaccinia-Antigen. Es zeigte sich eine signifikant erniedrigte Antwort auf ConA-Stimulation in Makroglobulinämie im Vergleich mit den Myelomen vom IgG-und IgA-Typ. Es bestand keine Korrelation zwischen Mitogen- oder Antigen-Antwort und der Serumkonzentration der Paraproteine oder polyclonalen Immunglobuline. Die Resultate zeigen, daß monoclonale Gammopathien, und hier besonders IgM-Paraproteinämien, mit einer gestörten zellulären Immunfunktion einhergehen, was mit der klinischen Beobachtung gehäufter viraler und fungaler Infektionen übereinstimmt.
