Zusammenfassung

Bei 21 Patienten mit chronischer lymphatischer LeukÄmie (CLL) und 8 Normalpersonen wurde die Anzahl der DNA-synthetisierenden peripheren Blutlymphozyten autoradiografisch untersucht. Die Lymphozyten wurden dabei mit Hilfe des EN-Rosettentests in T-Zellen und Nicht-T-Zellen differenziert. Es zeigt sich eine normale T-Zellproliferation und eine erhöhte Nicht-T-Zellproliferation im Stadium O-I. In den fortgeschritteneren Krankheitsstadien erfÄhrt die Proliferation für T- und Nicht-T-Lymphozyten eine signifikante Steigerung. Die Proliferation der T-Zellen ist im Stadium IV auf das ca. 20fache, die der Nicht-T-Zellen auf das ca. 50fache gesteigert. Auf die Möglichkeit zu prognostischen Aussagen wird hingewiesen.

Summary

In 21 patients with chronic lymphocytic leukemia (CLL) and in 8 hematologically normal persons the number of DNA-synthesizing peripheral blood lymphocytes was investigated by autoradiographic techniques. The lymphocytes were differentiated by En-rosette tests into T and non-T lymphoid cells. The results show a normal number of proliferating T lymphoid cells and an increased number of proliferating non-T lymphoid cells in clinical stages O-I. Stages III–IV demonstrate a significant increase of the proliferation rate of both T and non-T lymphoid cells. The possible pathogenetic factors and the prognostic value of these results are discussed.
