    Notes: Summary In 39 patients with hemodynamically significant stenoses of the internal carotid artery thrombendarterectomy was performed. Hemorheological properties and plasma protein levels were studied pre- and postoperatively over a period of 14 days. In comparison to age-matched healthy controls preoperative plasma viscosity, red cell aggregation, fibrinogen, haptoglobin and alpha-1-antitrypsin were significantly elevated. After surgical trauma there was an increase in fibrinogen, alpha-1-antitrypsin, haptoglobin and ceruloplasmin, whereas alpha-2-macroglobulin, immunglobulin A and immunglobulin G decreased significantly. Plasma viscosity, red cell aggregation, red cell filterability, fibronectin and immunglobulin M remained unchanged. We conclude that our patients showed a non specific chronic “hematological stress syndrome” with raised acute phase reactants and corresponding hemorheological changes preoperatively; despite postoperative acute phase reaction no further deterioration of the rheological parameters could be observed; this might be caused by a decrease of plasma proteins with high frictional ratios compensating the increase of acute phase proteins. Besides, tissue damage and consecutive acute phase reaction in carotid arterial surgery seem to be of relatively minor degree.

    Description / Table of Contents: Zusammenfassung Aufgrund klinischer Befunde wurden 71 Patienten als chronisch lymphatische Leukämie (CLL) diagnostiziert, wobei die meisten den Stadien 0, I und II und nur 18% den Stadien III und IV nach Rai zuzuordnen waren. In allen Fällen stellte die Erkrankung eine Vermehrung der B-Lymphocyten Subpopulation dar (B-CLL). Beim Nachweis membrangebundener Immunglobuline (Ig) besaßen die leukämischen B-Zellen meist eine schwach ausgeprägte Immunfluoreszenz-Intensität. Damit in Übereinstimmung ergab die quantitative Bestimmung der Ig im Serum bei 72% der Patienten eine Verminderung einer oder mehrerer Ig-Klassen. Es war nicht möglich, die Zahl der B-Lymphocyten (und auch der T-Lymphocyten) oder die Konzentration der Ig im Serum mit dem Stadium der Erkrankung zu korrelieren. Um eine Abgrenzung der CLL von anderen lymphoproliferativen Erkrankungen, vor allem dem immunocytischen Lymphom, zu erreichen, wurde bei einem Großteil der Patienten ein Lymphknoten exstirpiert und histologisch sowie immunmorphologisch auf intracytoplasmatische Ig untersucht. Danach konnte die Diagnose einer CLL in 33 von 40 Fällen aufrechterhalten werden. Sechs Lymphknoten wurden als immunocytisches Lymphom erkannt, wobei sich klinisch in drei dieser Fälle eine Ig-Verminderung im Serum fand. Diese Beobachtung macht deutlich, daß die klinisch gestellte Verdachtsdiagnose einer CLL durch immunmorphologische Untersuchungen gesichert werden sollte.
    Notes: Summary Chronic lymphatic leukemia (CLL) was diagnosed in 71 patients based on clinical data. Most of the patients were in the stages 0, I and II, only 18% were in the stages III and IV according to Rai. In all cases, the disease was characterized by an increased number of B lymphocytes (B-CLL). The B cells mostly expressed a weak fluorescence intensity when tested for membrane bound immunoglobulins (Ig). In accordance to that, the quantitative measurement of Ig in the serum revealed a decrease of one or more Ig classes in 72% of the patients. No correlation existed between the number of B lymphocytes (and T lymphocytes) or the Ig concentration in the serum and the stage of the disease. To distinguish the CLL from related lymphoproliferative disorders, especially the immunocytic lymphoma, lymphnode biopsies were examined histologically and immunomorphologically for intracytoplasmic Ig. This examination confirmed the diagnosis of CLL in 33 out of 40 cases. Six lymphnodes were classified as immunocytic lymphoma of the lymphoplasmacytoid type. In three of the latter, the immunocytic lymphoma was clinically associated with decreased Ig concentrations in the serum. These findings emphasize that the clinically established diagnosis of CLL should be corroborated by immunomorphology.
