Étude comparative en soins primaires du taux d'INR dans la cible thérapeutique chez des patients traités par warfarine ou fluindione pour une fibrillation atriale. L’étude FLOWER (FLuindione Or WarfarinE – Result INR)

IntroductionThe aim of our study was to compare the time spent within the target INR or Time in Therapeutic Range (TTR) of patients treated with fluindione to that of patients treated with warfarin for non-valvular atrial fibrillation (NVAF) and followed in general practice, with the hypothesis of a better TTR with warfarin, which is the VKA most commonly prescribed in France.MethodLiberal nurses and general practitioners working in the Auvergne region recruited patients treated with fluindione or warfarin for NVAF. Patients' INRs (International Normalized Ratios) were recorded by medical analysis laboratories for 6 months. The primary endpoint was TTR, the secondary endpoint the number of hemorrhagic and/or thromboembolic events.ResultsOf the 342 participants with a mean age of 75.3 ± 9.8 years, 239 (70%) were treated with fluindione and 103 (30%) with warfarin. The mean number of INRs achieved per patient was 9.2 ± 4.0 in the fluindione group and 9.3 ± 4.0 in the warfarin group (p=0.73). The median TTR of fluindione was 81.9% [63.5; 94.1] and that of warfarin was 81.3% [65.6; 92.6] (p=0.98). Twenty-eight of 263 patients reported hemorrhage (10.6%) and 4 reported thromboembolic events (0.8%), with no significant difference between the groups.ConclusionThe TTRs of patients treated for NVAF with fluindione versus warfarin do not differ significantly over an observation period of 6 consecutive months in a patient population comparable to that of the publications in this field. However, these TTRs are significantly higher than those reported in the literature, with no difference between the two treatments.The TTRs of patients treated for VANF with fluindione versus warfarin do not differ significantly over a 6-month observation period in a patient population comparable to that of the publications in this indication.     

Intensification thérapeutique et autogreffe de cellules souches hématopoïétiques (CSH) dans le traitement des cancers du sein métastatiques : résultats du programme national Pegase 04

We report hereby the results of the french multicentric randomized PEGASE 04 protocol established to evaluate the impact on survival of high-dose chemotherapy over conventional chemotherapy for MBC patients.Patients and methods:Inclusion criteria were : age < 60 year, PS < 2, adenocarcinoma initially metastatic or in first relapse, chemosensitive disease. Randomization was done after 4-6 courses of conventionnal chemotherapy between high-dose (Mitoxantrone, 45 mg/m², Cyclophosphamide 120 mg/kg, Melphalan 140 mg/m²), and the pursuit of the same conventionnal chemotherapy. Between 09/92 and 12/96, 61 chemosensitive patients were enrolled 29 were referred to standard chemotherapy, 32 to intensive therapy. At randomization, 13 pts (21.3%) were in complete response and 48 in partial response.ResultsThe median progression-free survivals were 20 and 35.3 months in the standard and intensive groups (p=0.06). The relapse rates were respectively 79.3% vs 50.8% at 3 years and 90.8% vs 90.7% at 5 years. The median overall survivals were 20 and 43.4 months, with an overall survival rate of 18.5% vs 29.8% at 5 years (p=0.12).Conclusion The CMA regimen could prolong the progression-free survival of MBC patients, however without any significant impact on overall survival.Remerciements: Ligue Nationale Contre le Cancer, les laboratoires Amgen, Pharmacia-Upjohn et Lederle     

Les déficits immunitaires communs variables (DICV) : partie 2. Mise à jour clinique et thérapeutique

Common variable immunodeficiency disorders (CVID) are the most common symptomatic primary antibody deficiency in adults with an estimated prevalence of 1/25,000. The most frequent clinical manifestations are upper respiratory tract infections (including pneumonia, bronchitis, and sinusitis) predominantly with Streptococcus pneumoniae or H. influenzae. However, CVID are complicated in 20 to 30 % of cases of non-infectious manifestations which have been well characterized in recent years. Several complications can be observed including autoimmune, lymphoproliferative, granulomatous or cancerous manifestations involving one or more organs. These complications, mostly antibody-mediated cytopenias, are correlated with a decrease in the number of circulating switched memory B cells. Replacement therapy with polyvalent gammaglobulins has greatly improved the prognosis of these patients but it remains poor in the presence of digestive complications (especially in the case of chronic enteropathy and/or porto-sinusoidal vascular disease), pulmonary complications (bronchiectasis and/or granulomatous lymphocytic interstitial lung disease) and when progression to lymphoma. Much progress is still to be made, in particular on the therapeutic management of non-infectious complications which should benefit in the future from targeted treatments based on knowledge of genetics and immunology.
