    Notes: Summary 51Cr-platelet kinetic studies were performed in 77 patients with idiopathic thrombocytopenic purpura. The sequestration site was splenic for 63, splenic/hepatic for 7 or hepatic for remaining 7 patients. In 20 patients platelet survival was extremely shortened to 0–3 h, whereas only 26 patients had a survival time of more than 24 h. Those patients with low platelet counts also had a very short platelet survival time, whereas patients with higher platelet counts (〉50×109/l) had longer platelet survival times. 51 patients (66%) were splenectomized following the kinetic studies. 25 patients who had a splenic sequestration site had normalized platelet counts and 6 patients had platelet counts between 80–149×109/l 12 months after splenectomy (i.e. in 92% of cases with splenic sequestration site a full or partial remission). Of the 11 patients with a hepatic or splenic/hepatic sequestration site, 2 patients had full remission, 1 partial remission, 3 patients had minimal improvement and 5 other patients were treatment failures in respect to the splenectomy.

    Notes: Summary The dose-response relationship in the intravenous immunoglobulin treatment of idiopathic thrombocytopenic purpura was studied in 20 adult patients in a multicenter prospective crossover trial. The rate of response increases from 3 out of 11 (27%) to 6 out of 10 treatment periods (60%) by raising the 7S-IgG dose given on 5 consecutive days from 164.50±24.55 to 359.65±58.62 mg/kg body weight. The onset and duration of response as well as the peak platelet count were found to be independent of the doses. A long-term benefit induced by intravenous immunoglobulin treatment could be achieved in 2 out of 14 patients with chronic idiopathic thrombocytopenic purpura.

    Notes: Summary In a national multicentre trial in the FRG patients with Hodgkin's lymphoma in stages CS/PS III B/IV were entered into the HD 3 protocol and received induction chemotherapy with 3× (COPP+ABVD). Patients in complete remission (CR) received consolidation therapy by either radiotherapy (20 Gy IF) or chemotherapy (COPP+ABVD). Patients not in CR received salvage therapy (40 Gy in case of persisting nodal disease, else 4× CEVD chemotherapy). Between July 1983 and May 1987 230 untreated patients aged 15 to 60 qualified for this HD 3 protocol. This analysis is based on the first 137 patients evaluable for response. Of these, 86 (63%) achieved CR after induction chemotherapy. Including salvage therapy a total of 104 patients (76%) achieved CR. Univariate and multivariate prognostic risk factor analyses were performed using freedom from treatment failure (FFTF) as endpoint. Sex, age, splenectomy, bone marrow, liver and bone involvement had no prognostic impact nor had stage according to the Ann Arbor classification. In contrast, a pretreatment erythrocyte sedimentation rate (ESR) above 80 mm/h and a serum alkaline phosphatase (AP) above 230 IU/ml appeared as significant risk factors (p〈0.01, relative risk 2.3). The two parameters were not independent. Comparing a group A (ESR ≤ 80 and AP ≤ 230) versus a pooled group B (ESR〉80 and/or AP〉230) increased the difference (p〈0.001, relative risk of 2.8) which was also significant for survival (p〈0.04).

    Notes: Summary Protein C, a potent anticoagulant, has been detected in large amounts in some prothrombin complex concentrates (PCC). We extended these findings to eight PCC commercially available in West Germany detecting 0.82 to 1.92 plasma equivalent units of protein C antigen (PC: Ag) per unit factor IX. Infusion of PCC in four patients on stable oral anticoagulation resulted in a recovery of 58.6±10.9%. Estimated from the decrease in plasma levels of PC:Ag half life was 7.9±0.6 h.
