Abstract
Es wurde in vitro an 51 Patienten mit chronischer Polyarthritis die lymphozytäre Blastogenese zu PHA in Kulturen mit autologem oder normalem Plasma sowie auch die E-Rosetten-Bildung und die Gegenwart an Oberflächen-Ig untersucht. Während der Prozentsatz an T- und B-Zellen fast normal bleibt (52,1±2,1% und 18,1±2,1%, n.W. 55,6±2,0% und 16,2±0,8%), ist die Blastogenese in den Kulturen mit 25% autologem Plasma (5 399±709 cpm gegen dem Standartwert von 13 182±920 cpm) bedeutend verringert. Diese kehrt fast zu den Normalwerten zurück, sobald man das Patientenplasma mit Plasma von Gesunden ersetzt (12 189±1 081 cpm). Das rheumatoide Plasma ist imstande die Blastogenese von 11 normalen Personen zu hemmen (7 395±750 cpm). Eine vorhergehende Inkubation für 90′ der Lymphozyten von 14 Kontrollpersonen in rheumatoidem oder autologem Plasma führt zu einer bedeutenden Differenz in der E-Rosettenbildung (40,8±1,4% und 56,2±2,1%). Dies bedeutet das die funktionelle Hemmung der T-Lymphozyten bei dieser Krankheit auf plasmatische Faktoren zurückzuführen ist. The lymphocytes blastigenesis to PHA in culture with autologous or normal plasma, the formation of E rosettes and the presence of immunoglobulins on the lymphocytes surface were evaluated in 51 patients with chronic primary polyarthritis. While the percentage of T and B cells was almost normal (52.1±2.1% and 18.1±1.1%, N.V. 55.6±2.0% and 16.2±0.8%), the blastigenesis was significantly reduced in cultures with a 25% autologous plasma (5399±709 cpm compared to 13,182±920 cpm of the normal standard) and returned towards normal values when it was replaced by the plasma of a normal subject (12,189±1 081 cpm). The rheumatoid plasma was capable of reducing the blastigenesis in 11 normal subjects (7 395±750 cpm). The preincubation for 90′ of the lymphocytes of 14 controls in rheumatoid or autologous plasma induced a significant reduction in the formation of spontaneous rosettes (40.8±1.4% and 56.2±1.7%). These results suggest that the reduced function of the T lymphocytes in this disease is due to plasma factors.Keywords
