RESUMO

BACKGROUND: To evaluate haemostatic changes in coronary sinus (CS) and peripheral circulation (PC) in patients with cardiovascular disease (CAD) following PTCA. PATIENTS AND METHODS: We studied 12 patients scheduled for elective PTCA. Blood samples were obtained from CS and PC before angioplasty and after each balloon dilation. Expression of P selectin and several haemostatic parameters were determined. RESULTS: D-Dimers (DD) plasma levels were significantly increased in samples from CS. No significant differences were found in other haemostatic parameters. A significant decrease of thrombin-antithrombin III levels after PTCA was assessed. CONCLUSIONS: Intracoronary and peripheral hemostatic activation does not occur during and immediately following PTCA. No major differences in hemostatic parameters between CS and PC were observed in patients with CAD.

RESUMO

Philadelphia chromosome-positive chronic myeloid leukaemia (CML) developed three years after the diagnosis of Waldenström macroglobulinemia (WM) in a patient who had received chlorambucil and prednisone during this time. Treatment with busulphan was started and two and a half years later the died in blastic crisis. Six months before the blastic transformation of the leukaemia the amount of IgM, which remains stable (above normal values) along the chronic phase, initiates a decrease, reaching normal values in the phase of acute transformation. CML is a very rare second neoplasia in patients receiving anticancer drugs. The correlation between the decrease of IgM and the blastic crisis is very interesting. We do not find an explanation for this finding although similar observations have been described heralding the appearance of second neoplasias in WM, and one might speculate with a possible role of IgM in the control of chronic phase of the myeloid leukaemia or if the overgrowth of blastic cells could overwhelm the development of lymphoplasmacytoid cells.
