Sometimes the relaxation after stress may trigger a migraine attack. This is the principle that underlies that particular variant of migraine called "weekend headache". We hypothesize the presence in weekend headache prone subjects of a particular psychological background, different from that of common migraine sufferers. In order to detect possible differences supporting our hypothesis, we studied 104 new outpatients: 46 patients suffering from headache only on weekends (23 males and 23 females) and 58 matched common migraineurs (26 males and 32 females) with no weekend predilection. The psychological assessment was performed using the following psychometric tools: MMPI, BDI, STAIX1-X2. A clinical assessment of each patient was also carried out. Significant differences were found after statistically analyzing the test results. Most of the MMPI scales were found to be more elevated in both male and female weekend headache sufferers. From a clinical point of view, the weekend headache attacks proved to be similar to those of common migraine, but with a significantly higher incidence of concomitant symptoms. Our study confirms the important role that psychological factors play in the pathogenesis and clinical development of migraine and leads us to conclude that a psychic tension component is associated with the vascular one in weekend headache.
Pure RBC aplasia (PRCS) is a well-recognized complication after allogeneic hematopoietic stem cell transplantation (HSCT). Many therapeutic options are available to treat this condition, including erythropoietin, rituximab, bortezomib, plasma exchange, immunoadsorption, donor lymphocyte infusion, mesenchymal stem cells, antithymocyte globulin, and high-dose steroids; however, treatment outcomes are often variable and can sometimes lead to disappointing results. In this brief article we report our experience with 2 patients with PRCA after major ABO-incompatible HSCT who were resistant to multiple therapeutic interventions and who eventually benefited from treatment with eltrombopag, a thrombopoietin mimetic approved by the US Food and Drug Administration for the treatment of patients with immune thrombocytopenic purpura or severe aplastic anemia refractory to immunosuppressive agents or not eligible for HSCT. Data from these 2 patients show that eltrombopag was effective in treating erythroid aplasia and transfusion dependence after HSCT in patients who did not benefit from multiple previous treatments. Moreover, eltrombopag was well tolerated, with only a transient thrombocytosis requiring dose adjustment and no evidence of clonal evolution. Based on the positive results obtained in these 2 patients, we suggest that eltrombopag may have a favorable effect on unilineage cytopenias such as PRCA. Further studies in a large proportion of patients are mandatory to confirm these preliminary results.
Summary Deferasirox (DFX) is used for the management of iron overload (IOL) in many haematological malignancies including myelofibrosis (MF). The ‘RUX‐IOL’ study retrospectively collected 69 MF patients treated with ruxolitinib (RUX) and DFX for IOL to assess: safety, efficacy in term of iron chelation response (ICR) and erythroid response (ER), and impact on overall survival of the combination therapy. The RUX–DFX therapy was administered for a median time of 12.4 months (interquartile range 3.1–71.2). During treatment, 36 (52.2%) and 34 (49.3%) patients required RUX and DFX dose reductions, while eight (11.6%) and nine (13.1%) patients discontinued due to RUX‐ or DFX‐related adverse events; no unexpected toxicity was reported. ICR and ER were achieved by 33 (47.8%) and 32 patients (46.4%) respectively. Thirteen (18.9%) patients became transfusion‐independent. Median time to ICR and ER was 6.2 and 2 months respectively. Patients achieving an ER were more likely to obtain an ICR also (p = 0.04). In multivariable analysis, the absence of leukocytosis at baseline (p = 0.02) and achievement of an ICR at any time (p = 0.02) predicted improved survival. In many MF patients, the RUX–DFX combination provided ICR and ER responses that correlated with improved outcome in the absence of unexpected toxicities. This strategy deserves further clinical investigation.
611 Background: Improvements in hematologic parameters have been associated with iron chelation therapy (ICT) in transfusion-dependent patients with chronic anemia associated with hematologic malignancies. Data from a significant cohort of myelodysplastic syndromes (MDS) patients enrolled in the EPIC study and treated with deferasirox reported a percentage of 22.6% of erythroid responses. Several sporadic reports showed hematologic improvement in patients treated with deferoxamine or deferasirox in patients affected by myelofibrosis (PMF) and Aplastic Anemia (AA). The aim of this study was to retrospectively evaluate the hematologic response in the entire cohort of chronic anemias with iron overload receiving ICT with both deferasirox (DFX) or deferoxamine (DFO) in 6 hematological Italian centers from 1993 to 2011. Methods: 105 patients received ICT for at least 3 months. Sixteen were PMF, 8 AA, 75 MDS, 4 Chronic Myelomonocytic Leukemia (CMML), 2 Acute Myeloid Leukemia (AML). 30 patients received deferoxamine (6 PMF, 3 AA, 1 CMML, 2 AML, 18 MDS), and 68 deferasirox (9 PMF,5 AA, 3 CMML, 51 MDS), and 7 received deferasirox after a prior treatment with deferoxamine (1 PMF, 6 MDS). The median serum ferritin levels at the time of ICT was 1983 ng/ml and it was not significantly different between the two cohorts (p=0,8). Patients, at the time of ICT, had transfused a median of 30 Units of RBC (40 in the DFO cohort and 24.5 in DFX cohort, p=0.001). 25 out of 105 were receiving EPO therapy at the time of chelation, started at least 6 months before ICT, without a significant clinical improvement and three were receiving a JAK2 inhibitor started at least 1 year before ICT. Patients receiving any kind of therapy able to modify the erythroid response including azacitidine were excluded as well as patients receiving EPO started less than 6 months before ICT or JAK2 inhibitors or immunosuppressive therapy less than 12 months before. Hematological response (HR) was evaluated as follow: Achieving a RBC transfusion independency (complete HR) or Hematological improvement (HI-e) for patients showing a Hb increase of 1.5 g/dL or a reduction of 4 RBC transfusions/8 weeks (IWG 2006). Results: We retrospectively analyzed an unselected cohort of patients with transfusion dependent iron overload affected by different hematologic malignancies who received ICT outside clinical trials thus allowing the inclusion of high risk MDS/AML. 13 patients were not evaluable because they were receiving ICT for less than 3 months. 41 patients out of 92 (42.7%) evaluable patients achieved a hematologic response. In details: 18 (19,5%) became completely RBC transfusion independent. Six (1 AA, 3 RARS, 1 RCMD, 1 AML) were under DFO treatment and 12 (3 AA, 2 RA, 3 RARS, 1 RAEBII, 1 CMML, 2 PMF) under DFX. In addition, all 4 AA patients who achieved transfusion independency significantly increased the number of platelets ( median 17.000/mm3 before ICT and 35.000 and 55.000 after 6 and 12 months of ICT). Median time to response was 15 months for DFO and 3 months for DFX. 16 patients (17.3%) (6 RA, 4 RARS,1 RCMD, 1 RAEB, 4 PMF) obtained HI-e defined as a reduction of 4 U/8 weeks (5 in DFO and 11 in DFX cohorts) after a median of 6 months for both DFO and DFX. HI-e defined as an increased of 1.5 g/dL was observed in 7 patients (7.6%) ( 4 RA, 1 RARS, 1 RCMD, 1 PMF) after a median of 6 months for DFO and 3 for DFX. The hematologic improvement is not strictly related to an effective reduction of serum ferritin (p=0,4). Conclusions: Our data show a high rate of complete responses, mainly in AA and RARS but also in high risk MDS/AML representing 11% of those achieving complete transfusion independency. Notably 50% of AA achieved RBC and platelet transfusion independency. Despite the limitation due to the retrospective collection of data we suggest the ICT could result in hematologic improvement in a wide population including patients who are, at present, outside the published ICT guidelines. This study warrants further investigation on the mechanism of action of ICT in inducing erythroid response.
