RESUMEN

In a previous prospective study on 62 patients who underwent an HLA-matched allogeneic stem cell transplantation, we have observed that proportion of donor-derived CCR7(+)/CD4(+) T cells in the graft provided a predictive indicator of acute GVHD without interfering on chronic GVHD and relapse rate. Here we present our results on a confirmatory cohort of 137 consecutive patients. Indeed patients who received more than 76% of CCR7(+)/CD4(+) T cells in the graft developed more often acute GVHD be it of low or high grade than those who did not. Determination of the CCR7(+)/CCR7(neg) ratio of CD4(+) T cells in the graft provides a predictive indicator of acute GVHD and could help to define strategies of partial selective T cell depleted transplantation.

RESUMEN

The number of Hematopoietic Stem Cell Transplantations has globally taken off in the past decade. However, this increase in transplantation activity has put in the spotlight the need to create a special transplantation-skilled population of nurses. This type of specialisation allocated solely to this activity has not existed within the French nursing community until now. In the attempt to harmonize clinical practices between different French transplantation centers, the French Society of Bone Marrow Transplantation and Cell Therapy (SFGM-TC) sets up its forth annual series of workshops which brought together practitioners from all member centers and took place in September 2013 in Lille. Here we report our results and recommendations regarding the implementation of a transplant nurse status for post-transplant follow-up care.

RESUMEN

Haploidentical allogeneic stem cell transplantation (CST) has globally taken off in the past decade. It appears to be a valid alternative to other sources of stem cells; however, further research is necessary to validate the use of this approach in standard patient care. In the attempt to harmonize clinical practices between different French transplantation centers, the French Society of Bone Marrow Transplantation and Cell Therapies (SFGM-TC) set up its fourth annual series of workshops which brought together practitioners from all of its member centers. These workshops took place in September 2013 in Lille. This is part one of the recommendations regarding allogeneic stem cell transplantation from an HLA-haploidentical related donor.

RESUMEN

We present a search for differences in the oscillations of antineutrinos and neutrinos in the Super-Kamiokande-I, -II, and -III atmospheric neutrino sample. Under a two-flavor disappearance model with separate mixing parameters between neutrinos and antineutrinos, we find no evidence for a difference in oscillation parameters. Best-fit antineutrino mixing is found to be at (Δm2,sin2 2θ)=(2.0×10(-3) eV2, 1.0) and is consistent with the overall Super-K measurement.

RESUMEN

Antifungal prophylaxis (AP) has dramatically changed the epidemiology of invasive aspergillosis (IA). To better understand the differences in terms of clinical significance of IA between allogeneic stem cell transplantation (allo-SCT) recipients and patients treated for leukemia, we report a single-center study of 735 unselected consecutive patients treated between 2000 and 2004, before the era of systematic AP. Probable or confirmed IA were observed in 29 patients (2008 EORTC/MSG criteria), including 7/235 undergoing allo-SCT (5.2%), 19/380 treated for acute leukemia (5.0%), 1/116 for chronic lymphocytic leukemia (0.9%) and 2/104 for myelodysplastic syndrome (1.9%). In allo-SCT recipients, IA occurred later than in leukemia patients, after the neutropenic period. The median time between the last treatment and the diagnosis of IA was 231 days (range, 68-341) in allo-SCT recipients and 17 days (6-57) in leukemia patients (P<0.001). Importantly, the 7 cases of IA after allo- SCT occurred only in patients treated with corticosteroids for graft-versus-host disease (GVHD). Mortality directly related to IA was 24%. The 100-day, 2-year and 10-year overall survival were 42.9%, 0%, 0% in allo-SCT recipients compared to 68.1%, 18.2%, 13.6% in leukemia patients, respectively (P≥0.05). These poor outcomes were mainly attributable to non-relapse mortality (NRM). In conclusion, our data allows distinguishing 2 types of IA occurring at different time in the treatment course. In both cases, the NRM is very high and treatment remains challenging. Thus, systematic broad-spectrum AP against Aspergillus should be considered in acute leukemia patients during the neutropenic phase and in all patients undergoing allo-SCT who develop GVHD.

RESUMEN

Chronic GvHD-related keratoconjunctivitis sicca (cGvHD-related KCS) can significantly alter the quality of life of patients after allogeneic hematopoietic stem cell transplantation. The aim of this work was to assess the efficacy and tolerability of scleral lenses to treat severe cGvHD-related KCS. In this retrospective, multicenter study, we included 60 consecutive patients diagnosed with cGvHD-related KCS and fitted with scleral lenses. Patients were evaluated at baseline and at 2 months with the following tests: the Ocular Surface Disease Index (OSDI) to assess quality of life, the Oxford score to grade corneal damage and the logarithm of minimal angle of resolution (Log MAR) scale to determine visual acuity. We observed improvement in quality of life in 58 patients (97%). All parameters improved at 2 months. We observed significant differences at 2 months compared with baseline for the mean OSDI (86 versus 30, respectively, P<0.001), the mean Oxford score (3.2 versus 1.3, respectively, P<0.001) as well as visual acuity (Log MAR of 0.33 versus 0.10, respectively, P<0.001). Treatment with scleral lenses was discontinued in only 5 patients (8%) with a median follow-up of 20.5 months (range: 2-125 months). Scleral lenses were very efficient and well tolerated in patients with severe cGvHD-related KCS.

RESUMEN

The monitoring of the minimal residual disease by Wilms' tumor 1 expression (MRDWT1) is a standardized test, which can be used in over 80% of patients with AML. To investigate the prognostic value of MRDWT1 in patients undergoing allogeneic stem cell transplantation (allo-SCT) for AML, MRDWT1 was monitored 3 months after transplantation in 139 patients. MRDWT1 positivity did not lead to any therapeutic intervention. Median follow-up was 39.3 (6.4-99.8) months. Patients with positive MRDWT1 at 3 months experienced more often post-transplant relapse (27/30, 90%) than those with negative MRDWT1 (16/109, 14.7%) (P<0.0001). Similarly, a shorter 3-year event-free survival (EFS) was observed in MRDWT1-positive patients (10% vs 72.3% in MRDWT1-negative patients, P<0.0001). The correlation between relapse and MRDWT1 was stronger in blood than in bone marrow samples. Multivariate analysis confirmed the detrimental role of 3-month positive MRDWT1 for relapse (hazard ratio (HR): 15.42; 95% confidence interval (CI): 7.53-31.59; P<0.0001) and EFS (HR: 10.71; 95% CI: 5.41-21.21; P<0.0001). Interestingly, 3-month chimerism was less predictive of relapse than positive MRDWT1. In conclusion, our results demonstrate the usefulness of peripheral blood MRDWT1 monitoring in identifying very high-risk patients, who could benefit from an early preemptive treatment, and those who do not need such an intervention.

RESUMEN

Sclerotic chronic GvHD (cGvHD) is one of the most severe complications after allo-hematopoietic stem cell transplantation (HSCT). Risk factors associated with this complication remain not very well defined. With the aim to define a pre-transplantation risk profile, we have conducted a French retrospective analysis in 705 consecutive patients between 2005 and 2010. Analyses to determine pre-transplantation risk factors included as variables: patient and donor age, kind of donor, HLA matching, ABO matching, sex-matching, diagnosis, stem cell source, gender, GvHD prophylaxis and antithymocyte globulin (ATG) in the conditioning regimen. The cumulative incidence of sclerotic cGvHD was 18% (95% CI, 16.6-19.6) 3 years after onset of cGvHD. In univariate analysis, we found a significantly lower number of sclerotic cGvHD form in patients transplanted from cord blood cells (P=0.0021), in patients with a one mismatched donor (P=0.041) and in patients who had received ATG in the conditioning regimen (P=0.002). In multivariate analysis, factors associated with an increased risk of sclerotic cGvHD were young patient age, multiple myeloma and PBSC as the stem cell source. ATG in conditioning regimen and cord blood unit as the stem cell source were associated with a lower risk.

RESUMEN

The IgM globulin response has been measured following the onset of primary Q fever infections. A complement fixation test method was used to measure the IgM after separation by ultracentrifugation in a sucrose density gradient. Specific IgM was demonstrable between 2 and 10 wk after onset of symptoms. The test can be used to confirm a recent infection when only a 'convalescent' blood specimen has been collected and will be useful in the assessment of workers' compensation claims.

RESUMEN

BACKGROUND: Decision making about the opportunity of starting or continuing hormone replacement therapy (HRT) in menopause should rely on an overall evaluation of its risks and benefits for the women's health; the evaluation of HRT cost-benefit ratio, however, should include its possible outcomes from an economical point of view. In this view, and with the certainty that menopausal patients should be protected by proper treatments, our case series has been evaluated in order to improve the quality of our clinical schedules for both their access to HRT and the treatment follow-up. METHODS: Two groups of patients have been considered the first one consisted of 560 women observed during '97 for climacteric symptoms and candicated to begin HRT. The second one consisted of 100 women on HRT for 1 to 6 years. In the first group we considered which test and with which frequency were responsible for stopping or delay the beginning of therapy; while in the second group we evaluated the reasons for stopping treatment. RESULTS AND CONCLUSIONS: On the basis of our experience, the exams required before starting HRT seem to be the following: patient history, mammography, densitometry and endometrial sample as well as the parameters of glucose lipidic, coagulative and hepatic metabolism. Densitometry is useful in the annual follow-up only in patients with bone alterations from the beginning. The same exams seem required for the follow-up, with the exception of bone densitometry which should be performed yearly only in patients with bone demineralization.

RESUMEN

In this study we evaluated different metabolic parameters and bone mass, before and after 18 months of treatment by transdermal estradiol associated with oral sequential MPA in menopause. We treated 46 physiologically postmenopausal patients (44-55 years old) for at least six months, by TTS/E2 50 mcg for 3 weeks and MPA 10 mg for the last 12 days of estradiol treatment. The fourth week was free of therapy. Before treatment and after 18 months, we evaluated bone density (BMC/BW), body mass index (W/sqH), systolic and diastolic blood tension, lipid parameters, coagulation parameters, mineral metabolism with statistical elaboration of our results. After therapy we found a significant decrease in diastolic blood tension, a significant reduction in triglyceride levels and a slight but significant increase in HDL-cholesterol levels. The only variation in coagulation parameters was a decrease of circulating fibrinogen. No variation occurred in the body mass index, mineral metabolism or bone density. In conclusion even long term transdermal treatment seems metabolically well tolerated and very useful in relieving neurovegetative climacteric symptoms and dystrophic genital ones.

RESUMEN

In an attempt to reduce the incidence of chronic GVHD (cGVHD) after reduced-intensity conditioning (RIC), we used BM instead of PBSC and added melphalan 100 mg/m(2) to the classical association of fludarabine, 30 mg/m(2)/day for 3 days and TBI, 200 cGy (FLUIM regimen). Between 2000 and 2012, 51 patients received BM with the FLUIM regimen (group A), and 124 received BM (n=22) or PBSC (n=102) with another RIC regimen (group B). Donors were siblings (n=123) or HLA-matched 10/10 unrelated (n=52). Full donor-type chimerism at day 100 was more often recorded in group A (86%) than in group B (62%); P<0.001. There was no difference between the two groups in terms of OS and EFS, acute GVHD, relapse and non-relapse mortality incidence. cGVHD occurred more often in group B (41%) than in group A (23%); P=0.021. In multivariate analysis, the two risk factors associated with the development of cGVHD were conditioning in group B (hazard ratio (HR)=2.871, 95% confidence interval (CI) (1.372-6.006); P=0.005) and CD34(+) count (HR=1.009, 95% CI (1.006-1.011); P<0.001). In conclusion, the FLUIM regimen followed by BM leads to more frequent full-donor chimerism and a reduced incidence of cGVHD without compromising relapse and survival.

RESUMEN

T-cell reconstitution after allo-SCT initially depends on homeostatic peripheral expansion of donor T cells, the level of which may promote the differentiation of alloreactive and tumor-reactive effectors. IL-7 and IL-15 exert their effect as key homeostatic cytokines. We prospectively investigated plasma levels of IL-7 and IL-15 in a homogeneous group of 40 patients in CR of their hematologic malignancy undergoing myeloablative, fully (10/10) HLA-matched BMT. IL-7 and IL-15 proceeded along similar kinetic courses, peaking at wide ranges (3.8-30.2 and 14.3-66 pg/ml, respectively) on day +14 when all patients were profoundly lymphopenic. Occurrence and grade of subsequent acute GVHD were significantly associated with heightened day +14 IL-7 and IL-15 levels. Association of peak IL-7 level to grade 2-4 acute GVHD was confirmed by Cox multivariate analysis (hazard ratio (HR)=5.38; P=0.022). Malignancy relapse was significantly associated with reduced day +14 levels of IL-15 (Cox multivariate analysis: HR=0.93; P=0.035). Plasma IL-7 and IL-15 levels in the early post transplantation period are therefore biomarkers that can help predict subsequent development of acute GVHD and malignancy relapse.

RESUMEN

Treatment of sclerodermatous chronic GVHD (cGVHD) remains disappointing. Imatinib mesylate enables selective, dual inhibition of the transforming growth factor beta (TGFbeta) and PDGF pathways. Recently, the drug's effects on fibroblasts have been reported in both in vitro and in vivo studies. The inhibition of fibroblast growth and decreased collagen production in dermal fibroblasts is thus a logical therapeutic approach. Two patients who developed refractory sclerodermatous cGVHD following allo-SCT received imatinib mesylate at the dose of 400 mg/day. In both patients, the scleroderma symptoms disappeared within 3 months of initiation of the treatment. At the time of this report, the two patients were both alive and had a very good skin response. This report shows that imatinib is effective in patients with refractory sclerodermatous cGVHD. Considering its well-documented clinical profile in other diseases, imatinib is a promising candidate for the treatment of sclerodermatous cGVHD.

RESUMEN

OBJECTIVE: To analyze prescriptions in a general-practitioner database over 1 year to determine the frequency, the characteristics, and the monitoring of the severe potential drug-drug interactions (DDIs). METHODS: We retrospectively analyzed the clinical records from 16 general practitioners in the Veneto region, an area in northern Italy. The study covered the period from January 1 to December 31, 2004. We selected all severe and well-documented interactions according to the book Drug Interaction Facts by David S. Tatro (Facts and Comparisons, St. Louis, MO, 2006). We grouped severe potential DDIs according to their specific potential risk, and for the most frequently interacting drug pairs, we investigated whether some specific tests had been prescribed by physicians for safety monitoring. RESULTS: During the study period, 16,037 patients (55% female) with at least one drug prescription were recorded, and a total of 185,704 prescriptions relating to 1,020 different drugs were analyzed. Ramipril was the most frequently prescribed drug followed by acetylsalicylic acid and atorvastatin. The final number of different types of severe potential DDIs was 119, which occurred 1,037 times in 758 patients (4.7% of the total number of patients). More than 80% of drugs involved in severe potential DDIs were cardiovascular drugs. Digoxin was the most frequently involved drug. Electrolyte disturbances, increase in serum digoxin levels, risk of hemorrhage, severe myopathy or rhabdomyolysis, and cardiac arrhythmias were the most commonly implicated potential risks. When considering patients using digoxin with loop or thiazide diuretics for more than 5 months, 72% had at least one test to monitor potential digoxin toxicity, whereas 28% had no tests. Sixty-four percent of patients using digoxin with amiodarone, verapamil, or propafenone had an ECG and/or digoxin monitoring, and 36% of them did not have any tests. CONCLUSIONS: The present study revealed that, in a group of Italian general practitioners, the risks of severe potential drug interactions are relatively low and the drugs concerned are few. Analyses of specific tests showed that physicians are generally aware of the potential risks caused by digoxin drug associations. However not all patients were closely monitored and this should be improved.

RESUMEN

OBJECTIVE: To analyse and discuss the use and the safety profile of individual antiepileptic drugs (AEDs) in Italy. METHODS: The AED safety data referred to the period January 1988-June 2005 and were obtained from the database of the Italian Interregional Group of Pharmacovigilance (GIF). This database collects all spontaneous reports of suspected adverse drug reactions (ADRs) from six Italian regions which are the main contributors to the Italian spontaneous reporting system. Individual AED consumption data (defined daily dose/1,000 inhabitants per day) in the GIF area and in the whole of Italy referred to the period January 2003-June 2005 and were derived from drug sales data (Institute for Medical Statistics Health). RESULTS: Phenobarbital was the most frequently used AED in the GIF area (4.26 DDD/1,000 inhabitants per day) followed by carbamazepine (1.97), valproic acid (1.33) and gabapentin (1.10). AED consumption in the whole of Italy showed a similar pattern. Gabapentin was the most frequently used AED among newer AEDs. In the GIF database 37,906 reports (up to June 2005) were present; 666 of them (1.76%) were associated with at least one AED (Anatomical Therapeutic Chemical code N03A). The AED with the highest number of reports was carbamazepine (208 reports) followed by phenobarbital (98), gabapentin (80), phenytoin (56), valproic acid (55), lamotrigine (51), oxcarbazepine (43) and vigabatrin (35). Use and toxicity profile were evaluated only for AEDs associated with at least 30 reports. Skin reactions were the most frequently reported ADRs, followed by haematological, general condition, hepatic, neurological and gastrointestinal adverse reactions. Phenobarbital, lamotrigine, carbamazepine and phenytoin had the highest percentage of skin reactions (69, 67, 60 and 54%, respectively). Many haematological reactions were reported for each AED; the highest percentage was related to valproic acid (25%). Vigabatrin was associated with the highest percentage of reactions related to hearing, vision and other senses (97%). Phenytoin and valproic acid had the highest percentage of hepatic reactions (30 and 20%), whereas gabapentin of nervous system, psychiatric, gastrointestinal and urinary reactions (26, 21, 21 and 14%, respectively) and phenobarbital of musculoskeletal reactions (13%). CONCLUSIONS: In Italy antiepileptic drug therapy appears to be still dominated by traditional drugs. Our analysis showed a different safety profile related to each AED. Some of the drug-adverse reaction associations discussed are not included in the Italian drug leaflets or have not been reported before in the literature.

RESUMEN

We studied 18 early (6 to 36 months) postmenopausal patients with a mean age of 51 years (47-53), who had never undergone hormone replacement therapy before and had no contraindications to hormone replacement. All cases of menopause were spontaneous. The treatment consisted in the continuous transdermal administration of 17-beta-estradiol (50 microg/daily) by skin patch to be replaced every 84 hours. The patients were further treated with a two-week progestogen administration every fortnight. This consisted of transdermal norethisterone acetate (0.25 mg/daily) combined with estradiol in the same patch in the first year, and oral dihydrogesterone (10 mg/daily) in the second year, without wash-out period. Before treatment (T0), and at the 12th (T1) and 24th (T2) month we measured the body mass index, the arterial blood pressure (AP), lipoproteins, coagulation parameters and bone metabolism parameters. The systolic pressure presented mean values (+/-SD) equal to 128.5+/-10.2 mmHg (T0), 131.1+/-7.4 mmHg (T1) and 130.4+/-7.5 mmHg (T2). Diastolic pressure values showed mean value ranging from 85.4+/-8.7 mmHg (T0) to 83.9+/-5.3 (T1) and 83.4+/-5.8 mmHg (T2). The detailed analysis of values of triglycerides, HDL cholesterol, apolipoprotein A1, apolipoprotein B and coagulation parameters at different times of therapy showed no statistically significant changes. With regard to bone metabolism, no statistically significant changes from baseline values were observed in parathormone, alkaline phosphatase, calcitonin, urinary calcium/creatinine ratio, and bone mineral content expressed by the bone density.
