    Notes: Abstract Seventy-nine children with haemolytic uraemic syndrome (mean age 28 months) were randomly assigned either to a group receiving plasma infusions (plasma group,n=39) or to a group treated conservatively (control group,n=40). The duration of haemolysis, thrombocytopenia and anuria was similar in the two groups. Serum creatinine levels were similar in the two groups at the 1-month follow-up but were higher in the control group at 3 months (plasma group 49±14, control group 66±28 μmol/l;P〈0.02) and at 6 months (plasma group 48±13, control group 63±21 μmol/l;P〈0.005). The prevalence of proteinuria was also higher in the control group at the 6-month follow-up (plasma group 17%, control group 46%;P〈0.02). However differences were no longer significant after 1 year. Renal tissue was examined in 54 cases (plasma group,n=27; control group,n=27). Diffuse cortical necrosis was present in 7 cases in the control group but was absent in the plasma group (P〈0.02). Taking into consideration the higher serum creatinine levels, the higher prevalence of proteinuria during the first 6 months of follow-up in the control group and the presence of diffuse cortical necrosis in this group compared with the plasma group, we conclude that plasma infusions should be regarded as beneficial. Further study is needed to determine which plasma fraction is involved.

    Notes: Abstract Background: The treatment of Hodgkin's disease (HD) at advanced stages relies mainly upon multi-agent chemotherapies (CT), while the role of radiation therapy has not been definitely identified. The aim of this report is to analyze the 10-year results of a prospective study including 133 patients with HD clinical stages (CS) IIIA to IVB treated by three monthly courses of ABVD (adriamycin, bleomycin, vinblastin, and dacarbazine) followed by high-dose subtotal or total lymphoid irradiation [(S)TLI]. Patients and methods: From 1 October 1981 to 30 September 1988, 133 adult patients with HD CS IIIA (45), IIIB (33), IVA (seven) and IVB (48) were entered in the non-randomized multicentric prospective trial POF81/34. The number of involved nodal areas (NINA), and the number of visceral sites (NVIS) involved were registered in all patients; patients with bulky mediastinal tumor (BuMT) (mediastinal mass ratio ≥0.45) were also identified. All patients received three monthly cycles of ABVD. Patients in complete remission (CR) or partial remission (PR) after completion of CT received a (S)TLI including the spleen (involved sites 40 Gy, non-involved 30 Gy); initially involved lung(s) and liver received 18 and 20 Gy, respectively; and patients not in CR or PR after CT or RT received salvage treatments. Univariate and multivariate analyses were performed to identify the factors contributing significantly to the prognosis; initial characteristics, as well as status after the three cycles of CT, were entered in the model. Results: Of the 133 patients, 74 (55.6%) entered in CR after CT and 116 (87.2%) after completion of radiation therapy. Ten-year freedom from progression (FFP), freedom from tumor mortality (FFTM) and survival rates were 70.4%, 78.9% and 70.6%, respectively. According to univariate analysis the NVIS (≤ one vs. ≥ two) was the only initial factor simultaneously influencing 10-year FFP (73.9% vs. 38.2%) FFTM (82.5 vs. 34.1%) and survival (73.5% vs. 17.3%) rates; on the other hand, the NINA (≤ four vs. ≥ five) influenced FFP (81.4% vs. 60.7%) and FFTM rates (87.3% vs. 71.4%) while symptoms (A vs. B) influenced FFP (80.7% vs. 63.3%) and survival (82.8% vs. 61.2%) rates. Finally, age (〈40 vs. ≥40) influenced survival rate only (79.2% vs. 50%). According to multivariate analysis, NVIS and NINA had an independent impact on FFP and FFTM, while survival was modified by the NVIS and age. The post-CT status (CR vs. no CR) had a major impact on FFP (85.3% vs. 64.9%) FFTM (92.1% vs. 63.3%) as well as on survival (78.6% vs. 54.7%) rates in both univariate and multivariate analyses. Complications of therapy were mainly due to RT: 11 patients acquired second malignancies, six developed lung fibrosis or severe pulmonary infections, three developed intestinal obstructions and six developed angina pectoris or carotid stenosis. Conclusions: Tumor burden (identified by the number of involved nodal areas and the number of visceral sites) and the response to initial CT were the two independent factors influencing the outcome of this group of 133 patients with HD, CSIII and IV treated by three cycles of ABVD followed by high-dose [(S)TLI].
