RESUMO

Hormographiella aspergillata is a basidiomycete exceptionally involved in invasive fungal infections (IFI). We report a case of H. aspergillata pulmonary infection in a 30-year-old female in a context of pancytopenia and relapsed of acute myeloid leukemia (AML). She presented with fever, thoracic pain, left pleural effusion and pneumonia, diagnosed on chest X-ray and CT-scan. Direct examination of a bronchoalveolar lavage (BAL) specimen performed on day (d) 10 was negative, while the culture was positive on d30. H. aspergillata was suspected, considering macroscopic and microscopic examination. Its identification was confirmed using Microflex® Bruker mass spectrometry and pan-fungal (PF)-PCR assay followed by DNA sequencing. After this initial diagnosis, the patient was monitored for 2.8 years. She was treated with liposomal amphotericin B and/or voriconazole until switching to isavuconazole on d298 due to side-effects. This antifungal treatment was maintained until d717 and then discontinued, the patient being considered as cured. Over this follow-up period, the patient was submitted to recurrent pulmonary sampling. Each time, cultures were negative, while PF - PCR assays and DNA sequencing confirmed the presence of H. aspergillata. The present case-report is the 32nd observation of H. aspergillata invasive infection showing that this IFI is still infrequent. Fifteen have occurred in patients with AML, which appears as the most frequent underlying disease favoring this IFI. Six recent case-reports in addition to ours highlight PF-PCR assays and DNA sequencing as relevant diagnostic tools that must be included in routine diagnosis and monitoring of IFI, specifically those due to rare basidiomycetes.

RESUMO

Relapse after allogeneic hematopoietic cell transplantation (allo-HCT) remains a major concern because it is associated with poor survival. A second allo-HCT is a valid option in this situation. During the 13th annual harmonization workshops of the francophone Society of bone marrow transplantation and cellular therapy (SFGM-TC), a designated working group reviewed the literature in order to update the second allo-HCT recommendations elaborated during the previous workshop (2016). The main indication for a second allo-HCT remains relapse of initial hematologic malignancy. Disease status; complete remission (CR), and relapse time after the first allo-HCT>6 months impact positively the overall survival of patients after the second allo-HCT. Donor change is a valid option, particularly if there is HLA loss on leukemic cells after a first haploidentical or following a mismatched allo-HCT is documented. Reduced intensity conditioning is recommended, while a sequential protocol is a reasonable option in patients with proliferative disease. A post-transplant maintenance strategy after hematological recovery is recommended as soon as day 60, even if the immunosuppressive treatment has not yet been stopped. Hypomethylating agents, and targeted therapies such as anti FLT3, anti BCL2, anti-IDH1/2, TKI, anti-TP53, anti-CD33, anti-CD19, anti-CD22, anti-CD30, check point inhibitors, and CAR-T cells can be used as a bridge to transplant or as an alternative treatment to the second allo-HCT.

RESUMO

The combination of carmustine, etoposide, cytarabine, and melphalan (BEAM) followed by autologous stem cell transplantation (ASCT) is a commonly used intensification regimen for patients with Hodgkin lymphoma. As etoposide and cytarabine dosing are not defined, we conducted a retrospective, multicenter study, to compare efficacy and toxicity in 130 patients with Hodgkin lymphoma receiving etoposide and cytarabine at either 200 mg/m2/d (n = 50), 400 mg/m2/d (n = 35), or etoposide 200 mg/m2/d and cytarabine 400 mg/m2/d (n = 45). Progression-free survival and overall survival were not associated with the intensity of conditioning. Increased conditioning intensity was associated with longer duration of thrombocytopenia, a higher number of transfused RBC and platelet units and a higher frequency of mucositis, but serious adverse events or infectious complications were not increased. The intensity of BEAM regimen was not associated with survival but with the rate of cytopenia and mucositis advocating for the use of lower dosing in frail patients.

RESUMO

Acute myeloid leukemia (AML) can lead to life-threatening complications that may require intensive care unit (ICU) management. It has been advocated that early preemptive (ePE) ICU admission, before the onset of organ failure, could benefit some high-risk patients such as those with hyperleukocytosis. The aim of this study was to retrospectively analyze the outcome of newly diagnosed AML patients who required ICU admission in five academic centers with a special focus on patients with an ePE admission strategy, i.e., those transferred to the ICU without any organ failure (modified SOFA score ≤ 2 [omitting thrombocytopenia] and no life-sustaining intervention in the first 24 h following ICU admission) before the start of induction therapy. Between January 2017 and December 2019, 428 patients were included among which 101 were admitted to the ICU. Among patients requiring life-sustaining interventions (n = 83), 18 (22%) died while in the ICU but ICU survivors had the same survival as those not admitted to the ICU. Patients with an ePE admission (n = 18) had more comorbidities and high-risk disease features such as hyperleukocytosis but required no life-sustaining interventions while in the ICU. In a subgroup analysis of patients with hyperleukocytosis ≥ 50 G/l at diagnosis (n = 85), patients not admitted to the ICU and those admitted with an ePE strategy had similar outcomes. This study provides encouraging results about ICU outcome in AML patients during induction therapy but the potential benefit of an ePE strategy must be confirmed prospectively.

RESUMO

Several scoring systems have been developed to assess suitability of individual patients for intensive acute myeloid leukemia (AML) therapy. We sought to compare the performance of these scores in a cohort of 428 consecutive adults with AML who received conventional induction chemotherapy in five academic centers in France. All scoring systems identified a subset of patients with increased 28 and 56-day mortality although the prediction accuracy was overall limited with C-statistics of ranging from 0.61 to 0.71 Overall survival (OS) prediction was more limited and restricted to scoring systems that include AML-related parameters. The outcome of 104 patients (24%) considered unsuitable for intensive chemotherapy based on criteria used in recent randomized trials was similar to that of the other 324 patients (28-day mortality, odds ratio [OR] = 1.88, P = 0.2; 56-day mortality, OR = 1.71, P = 0.21; event-free survival, hazard ratio [HR] = 1.08, P = 0.6; OS, HR = 1.25, P = 0.14) with low discrimination (C-statistic: 0.57, 0.56, 0.50, and 0.52 for 28-day, 56-day mortality, EFS, and OS, respectively). Together, our findings indicate that the accuracy of currently available approaches to identify patients at increased risk of early mortality and shortened survival after intensive AML therapy is relatively limited. Caution regarding the use of available scoring systems should be warranted in clinical decision-making.

RESUMO

BACKGROUND: Early antibiotic discontinuation according to the Fourth European Conference on Infections in Leukaemia (ECIL-4) recommendations is not systematically applied in high-risk neutropenic patients with haematological malignancies. METHODS: A retrospective multicentre observational study was conducted over 2 years to evaluate the safety of early antibiotic discontinuation for fever of unknown origin (FUO) during neutropenia after induction chemotherapy or HSCT, in comparison with a historical cohort. We used Cox proportional hazards models, censored on neutropenia resolution, to analyse factors associated with febrile recurrence. RESULTS: Among 147 included patients in the ECIL-4 cohort, mainly diagnosed with acute leukaemia (n = 104, 71%), antibiotics were discontinued during 170 post-chemotherapy neutropenic episodes. In comparison with the historical cohort of 178 episodes of neutropenia without antibiotic discontinuation, no significant differences were observed regarding febrile recurrences [71.2% (121/170) versus 71.3% (127/178), P = 0.97], admission in ICUs [6.5% (11/170) versus 11.2% (20/178), P = 0.17], septic shock [0.6% (1/170) versus 3.9% (7/178), P = 0.07] and 30 day mortality [1.4% (2/147) versus 2.7% (4/150), P = 0.084]. In the ECIL-4 cohort, the rate of bacteraemia in case of febrile recurrence was higher [27.1% (46/170) versus 11.8% (21/178), P < 0.01] and antibiotic consumption was significantly lower (15.5 versus 19.9 days, P < 0.001). After early antibiotic discontinuation according to ECIL-4 recommendations, enterocolitis was associated with febrile recurrence [HR = 2.31 (95% CI = 1.4-3.8), P < 0.001] and stage III-IV oral mucositis with bacteraemia [HR = 2.26 (95% CI = 1.22-4.2), P = 0.01]. CONCLUSIONS: After an FUO episode in high-risk neutropenia, compliance with ECIL-4 recommendations for early antibiotic discontinuation appears to be safe and mucosal damage was associated with febrile recurrence and bacteraemia. Prospective interventional studies are warranted to assess this strategy in high-risk neutropenic patients.

RESUMO

BACKGROUND: Three different scoring systems have been developed to assess pre-transplant comorbidity in allogeneic hematopoietic stem cell transplantation (Allo-HSCT): the Hematopoietic Cell Transplantation-Specific Comorbidity Index, the Comorbidity/Age index, and the Augmented Comorbidity/Age index. All were devised to predict overall survival (OS) and disease-free survival (DFS) survivals and non-relapse mortality (NRM) in patients receiving HLA-matched Allo-HSCT, but their performance has scarcely been studied in the haploidentical Allo-HSCT setting with post-transplant cyclophosphamide, a procedure in constant expansion worldwide. METHODS: To address this issue, their impact on survivals and NRM was examined in a cohort of 223 patients treated with haploidentical Allo-HSCT in four different centers. RESULTS: With a median follow-up of 35.6 months, 3-year OS, DFS, and NRM were 48.1% ± 4%, 46.3% ± 4%, and 30.0% ± 3%, respectively. No impact was found for any of the three comorbidity scores in univariate analysis. In multivariate analyses, the only three factors associated with lower OS were DRI (p < 0.001), an older age of recipients (≥55 years old, p = 0.02) and of donors (≥40 years old, p = 0.005). Older donor age was also associated with lower DFS and higher NRM. CONCLUSION: The comorbidity scores do not predict survivals nor NRM in haploidentical Allo-HSCT with PTCY, suggesting that pre-transplant comorbidities should not be a contra-indication to this procedure.

RESUMO

The negative impact of high serum ferritin level (SFL) before and after allogeneic hematopoietic cell transplantation (allo-HSCT) on outcomes is well recognized. However, it is poorly documented in adults undergoing haploidentical HSCT (haplo-HSCT) with post-transplantation cyclophosphamide (PTCY) for hematologic malignancies. The main objective was to assess the impact of pretransplantation and post-transplantation SFL on overall survival (OS), disease-free survival (DFS), and nonrelapse mortality (NRM) in patients undergoing haplo-HSCT with PTCY. The secondary objective was to identify factors associated with outcomes after transplantation by comparing SFL with other parameters related to the status of patients or donors. This multicentric retrospective study included 223 consecutive patients who underwent haplo-HSCT with PTCY in 4 French centers (Nantes, Angers, Besançon, and Brest) between October 2013 and January 2020. The impact of SFL on OS, DFS, and NRM at different time points was assessed based on receiver operating characteristic curves. With a median follow-up of 37.6 months (interquartile range, 23.5 to 51.0 months), 3-year OS, DFS, and NRM were 48.1 ± 4%, 46.3 ± 4%, and 30.0 ± 3%, respectively. Pretransplantation SFL had no impact on outcomes irrespective of the cutoff tested. Considering patients alive at 3 months post-transplantation, an SFL ≥3500 µg/L at 3 months was statistically significantly associated with worse 3-year OS (32.7 ± 8.7% versus 53.4 ± 7.2%; P = .01) and DFS (30.1 ± 8.2% versus 53.1 ± 7.1%; P = .008), with a trend toward higher NRM (33.2 ± 8.6% versus 17.6 ± 5.4%; P = .10). Similarly, high SFL (≥2700 µg/L) at 6 months post-transplantation was associated with worse 3-year OS (56.1 ± 9.1% versus 79.2 ± 6.0%; P = .02) and DFS (53.6 ± 8.7% versus 74.9 ± 6.2%; P = .01), with a trend toward higher NRM (21.4 ± 7.4% versus 8.2 ± 4.0%; P = .10). In multivariate analysis, high 3-month and 6-month FL remained associated with lower OS and DFS, with a trend toward higher NRM. Pretransplantation SFL appears to have no impact on outcomes in haplo-HSCT with PTCY, in contrast to what is documented in the matched allo-HSCT setting. In contrast, in the haplo-HSCT setting, high SFL early post-transplantation is associated with lower survival and a trend toward higher NRM.

RESUMO

This study explores the hypothesis that genetic differences related to an ethnic factor may underlie differences in phenotypic expression of myelodysplastic syndrome (MDS). First, to identify clear ethnic differences, we systematically compared the epidemiology, and the clinical, biological and genetic characteristics of MDS between Asian and Western countries over the last 20 years. Asian MDS cases show a 2- to 4-fold lower incidence and a 10-year younger age of onset compared to the Western cases. A higher proportion of Western MDS patients fall into the very low- and low-risk categories while the intermediate, high and very high-risk groups are more represented in Asian MDS patients according to the Revised International Prognostic Scoring System. Next, we investigated whether differences in prognostic risk scores could find their origin in differential cytogenetic profiles. We found that 5q deletion (del(5q)) aberrations and mutations in TET2, SF3B1, SRSF2 and IDH1/2 are more frequently reported in Western MDS patients while trisomy 8, del(20q), U2AF1 and ETV6 mutations are more frequent in Asian MDS patients. Treatment approaches differ between Western and Asian countries owing to the above discrepancies, but the overall survival rate within each prognostic group is similar for Western and Asian MDS patients. Altogether, our study highlights greater risk MDS in Asians supported by their cytogenetic profile.

RESUMO

We retrospectively examined the results of a new chemo-free approach combining blinatumomab with ponatinib (blina/pona) in 26 relapsed/refractory Philadelphia positive (Ph+) acute lymphoblastic leukemia (ALL) patients. All but one achieved complete morphologic remission, and 23 achieved a complete molecular response. With a median follow-up of 34.4 months, the median overall (OS) and event-free (EFS) survivals were 20 and 15.3 months, respectively. After blina/pona, 8 patients underwent an allotransplant (allo), while among the 18 non-transplanted cases, 15 received ponatinib in maintenance. Fifteen relapse/progressions occurred with a significant difference between allo and non allo cases (12.5% vs 82.3%, p = 0.003). However, OS and EFS were similar between both groups. Finally, blina/pona was well tolerated with eight reversible neurologic events and three cytokine release syndromes. Prospective studies are needed to properly assess the safety, tolerability and efficacy of the combination therapy.

RESUMO

PURPOSE OF THE STUDY: Invasive aspergillosis (IA) is the most prevalent invasive fungal disease (IFD) in neutropenic patients. Environment is the main source of Aspergillus spores aerosolization especially during building construction. International guidelines recommend mechanical protection during hospital building works; otherwise the use of antifungal prophylaxis is not clearly indicated. Our objective was to determine the efficacy of antifungal prophylaxis by posaconazole on IA incidence in acute myeloid leukemia population and to analyse the benefit of this prophylaxis and HEPA-filters during hospital buildings works. PATIENTS AND METHODS: We included patients treated for acute myeloid leukemia at Brest teaching hospital from January 2009 to December 2015. We compared incidence of IA in the group treated by posaconazole from 2012 to 2015 to the incidence of IA in the first group who did not receive antifungal prophylaxis (from 2009 to 2011). The one-year overall survival was also analyzed using the Kaplan-Meier method. RESULTS: 245 patients were enrolled including 151 treated with posaconazole. 23 IA were diagnosed between 2009 and 2011 (without antifungal prophylaxis), then 31 between 2012 and 2015 (with posaconazole) without statistical difference between the incidence densities (0.34 per 100 hospitalization-days vs. 0.30 per 100 hospitalization-days, p = 0.71). Incidence density of IA increased during building works (2.40 per 100 hospitalization-days vs. 0.28 per 100 hospitalization-days, p < 0.0001). The incidence density of IA significantly decreased during construction periods when posaconazole prophylaxis was used (1.59 per 100 hospitalization-days vs. 4.87 per 100 hospitalization-days p < 0.0001). CONCLUSION: Our study suggests, for the first time, the interest of antifungal prophylaxis in addition to HEPA filtration in prevention of IA during hospital building works.

RESUMO

BACKGROUND: Thromboses and phenotypic evolutions (leukemia, myelofibrosis) are the most frequent complications in polycythemia vera (PV) and essential thrombocythemia (ET). Aquagenic pruritus (AP) is not only PV symptom, but is also present in ET. The presence of pruritus in PV is associated with a lower risk of arterial thrombosis. AIMS: To date, no equivalent study has been done to analyse the impact of AP for ET patients. MATERIALS & METHODS: We used the data from our cohort of patients with myeloproliferative neoplasms seen in our institution (OBENE database, NCT02897297). We collect information at diagnosis, presence or not of AP and all types of complications during their follow-up. To avoid masked PV, all JAK2 positive cases were tested isotopic red mass cell if appropriate. RESULTS: Among 396 ET patients, presence of AP was found in 42 (10.6%). ET patients with AP were more proliferative, more symptomatic at diagnosis and more difficult to treat. Furthermore, they presented increased risk of thromboses (30.9 versus 17%, P = .03; OR = 2.2 [1.01;4.66]) and phenotypic evolutions (33.3 versus 13.3%, P = .0007; OR = 3.2 [1.44;6.77]), during follow-up. DISCUSSION: Aquagenic pruritus is classically associated to PV. But we confirmed here that AP is also present in ET and characterizes patients with higher risk of morbidity (thrombotic events and phenotypic evolutions). CONCLUSIONS: The systematic determination of the presence of AP in ET patients should permit us to better identify these high-risk patients for better management and follow-up.

RESUMO

Disease recurrence and graft dysfunction after allogeneic hematopoietic stem cell transplantation (allo-HSCT) currently remain among the major causes of treatment failure in malignant and non-malignant hematological diseases. A second allo-HSCT is a valuable therapeutic option to salvage those situations. During the 8th annual harmonization workshops of the french Society of bone marrow transplantation and cellular therapy (SFGM-TC), a designated working group reviewed the literature in order to elaborate unified guidelines on feasibility, indications, donor choice and conditioning in the case of a second allo-HSCT. In case of relapse, a second allo-HSCT with reduced intensity or non-myeloablative conditioning is a reasonable option, particularly in patients with a good performance status (Karnofsky/Lansky>80%), low co-morbidity score (EBMT score≤3), a longer remission duration after the first allo-HSCT (>6 months), and who present low disease burden at the time of second allo-HSCT. Matched related donors tend to be associated with better outcomes. In the presence of graft dysfunction (primary and secondary graft rejection), an immunoablative conditioning regimen is recommended. A donor change remains a valid option, especially in the absence of graft-versus-host disease after the first allo-HSCT.

RESUMO

Myeloproliferative neoplasms (MPN) are chronic disorders that can sometimes evolve into accelerated or leukemic phases. We retrospectively identified 122 patients with such blastic phases. The overall median survival was four months: 10.2 months for patients treated with intensive treatments compared to three months for best supportive care (p = .005). Azacytidine, intensive chemotherapies, or allogeneic stem cell transplantation gave the highest median survivals with 9, 10.2, and 19.4 months, respectively. Accelerated phases (AP) had a longer median survival compared to acute leukemia (4.8 months vs. 3.1 months; p = .02). In this retrospective and observational study, we observe that the longest survivals are seen in patients eligible for intensive treatments. Azacytidine shows interesting results in patients non-fit for intensive chemotherapy. Supportive care should probably be restricted to elderly patients and those with unfavorable karyotype. An early diagnosis of AP could also result in a better survival rate.

RESUMO

INTRODUCTION: Immediate empirical antibiotic therapy is mandatory in febrile chemotherapy-induced neutropenia, but its optimal duration is unclear, especially in patients with fever of unknown origin (FUO). OBJECTIVES: The primary objective of this 20-month prospective observational study was to evaluate the feasibility and safety of short-term antibiotic treatment in afebrile or febrile patients exhibiting FUO, irrespective of their neutrophil count. The secondary objective was to describe the epidemiology of all episodes of febrile neutropenia. METHODS: In the first phase of the study, empirical antibiotic therapy in FUO patients was stopped after 48 h of apyrexia, in accordance with European Conference on Infections in Leukaemia guidelines (n = 45). In the second phase of the study, antibiotics were stopped no later than day 5 for all FUO patients, regardless of body temperature or leukocyte count (n = 37). RESULTS: Two hundred and thirty-eight cases of febrile neutropenia in 123 patients were included. Neither the composite endpoint (p = .11), nor each component (in-hospital mortality (p = .80), intensive care unit admission (p = 0.48), relapse of infection ≤48 h after discontinuation of antibiotics (p = .82)) differed between the two FUO groups. Violation of protocol occurred in 17/82 episodes of FUO without any major impact on statistical results. Twenty-six (57.3%) and 22 (59.5%) FUO episodes did not relapse during hospital-stay (p = 1), and nine (20%) and five (13.5%) presented another FUO, respectively. One hundred and fifty-six episodes of febrile neutropenia (65.5%) were clinically or microbiologically documented, including 85 bacteremia. CONCLUSIONS: These results suggest that early discontinuation of empirical antibiotics in FUO is safe for afebrile neutropenic patients.

RESUMO

Direct oral anticoagulants (DOACs) have been approved to treat and prevent thrombotic events. However, they are not yet labeled for use in patients with active cancers. Myeloproliferative neoplasms (MPNs) are clonal chronic disorders with a high incidence of thrombotic events, for which low-dose aspirin (LDA) is the standard drug treatment. We analyzed efficacy and safety of DOACs prescription in patients treated for MPNs. An MPN database, the OBENE registry, was established at our institution. We collected biological and clinical data from diagnosis to last follow-up for every patient included in this study. Thrombotic and hemorrhagic events and hematologic evolutions were categorized as major events in the database. Of the 760 MPN patients in the OBENE registry, 25 (3.3%) were treated with a DOAC. Median follow-up duration was 2.1 years (0.12-4.3 years). The reasons for prescribing DOACs were atrial fibrillation and thrombotic events for 13 and 12 patients, respectively. We only observed one thrombotic event (4%) and three major hemorrhagic events (12%). A case-control study did not detect a significant difference in thrombotic or hemorrhagic events in patients treated with LDA and DOACs. These preliminary results suggest that DOACs may be highly efficient and safe for use in MPN patients.
