Adapting the Fitness Criteria for Non-Intensive Treatments in Older Patients with Acute Myeloid Leukemia to the Use of Venetoclax-Hypomethylating Agents Combination-Practical Considerations from the Real-Life Experience of the Hematologists of the Rete Ematologica Lombarda.

A retrospective survey was conducted in hematologic centres of the Rete Ematologica Lombarda (REL) on 529 older AML patients seen between 2020-2022. Compared to 2008-2016, the use of intensive chemotherapy (ICT) decreased from 40% to 18.1% and of hypomethylating agents (HMAs) from 19.5% to 13%, whereas the combination of Venetoclax/HMA, initially not available, increased from 0% to 36.7%. Objective treatment-specific fitness criteria proposed by SIE/SIES/GITMO in 2013 allow an appropriate choice between ICT and HMAs by balancing their efficacy and toxicity. Venetoclax/HMA, registered for patients unfit to ICT, has a unique toxicity profile because of prolonged granulocytopenia and increased infectious risk. Aiming at defining specific fitness criteria for the safe use of Venetoclax/HMA, a preliminary investigation was conducted among expert REL hematologists, asking for modifications of SIE/SIES/GITMO criteria they used to select candidates for Venetoclax/HMA. While opinions among experts varied, a general consensus emerged on restricting SIE/SIES/GITMO criteria for ICT-unfit patients to an age limit of 80-85, cardiac function > 40%, and absence of recurrent lung infections, bronchiectasis, or exacerbating COPD. Also, the presence of an adequate caregiver was considered mandatory. Such expert opinions may be clinically useful and may be considered when treatment-specific fitness criteria are updated to include Venetoclax/HMA.

"There Are Many of Us": Online Testimonies From "Pill Victims" as a New Form of Health Activism.

The French pill scare is usually presented as a "media debate" triggered by the case of Marion Larat, a young woman who suffered a stroke attributed to the pill she was taking. This article intends to focus on a practice that preceded, accompanied, and followed this health scare: the publication of online testimonies of thrombotic reactions posted on the website of the French Association of Victims of Pulmonary Embolism and Stroke Associated with Hormonal Contraception (Avep). Through a discourse analysis, we intend to analyze these online public self-reports as an activist practice aimed at criticizing the dominant medical discourse on contraception. Four discursive frames emerged: unpreparedness of women and doctors, denial of blame and search for the cause, breaking the silence and building solidarity, and collective action. The first two frames concern the process women put in place to obtain the right to speak about and criticize a medical practice. The right to speak is achieved through a concise narrative style focusing on facts, bodily manifestations, and risk factors. The second pair refers to the formation of pill victims as subjects with an ambivalent status and ephemeral agency. The testimonies build what we call "lone solidarity", that is, the creation of a social bond and action around a common experience of witnessing medical injustice that develops without any exchange between members. This proves to be inclusive and viral, but at the same time fiercely anti-representational with respect to political struggles or social identification.

Semi-automated socio-anthropologic analysis of the medical discourse on rheumatoid arthritis: Potential impact on public health.

BACKGROUND: The debilitating effects of noncommunicable diseases (NCDs) and the accompanying chronic inflammation represent a significant obstacle for the sustainability of our development, with efforts spreading worldwide to counteract the diffusion of NCDs, as per the United Nations Sustainable Development Goals (SDG 3). In fact, despite efforts of varied intensity in numerous directions (from innovations in biotechnology to lifestyle modifications), the incidence of NCDs remains pandemic. The present work wants to contribute to addressing this major concern, with a specific focus on the fragmentation of medical approaches, via an interdisciplinary analysis of the medical discourse, i.e. the heterogenous reporting that biomedical scientific literature uses to describe the anti-inflammatory therapeutic landscape in NCDs. The aim is to better capture the roots of this compartmentalization and the power relations existing among three segregated pharmacological, experimental and unstandardized biomedical approaches to ultimately empower collaboration beyond medical specialties and possibly tap into a more ample and effective reservoir of integrated therapeutic opportunities. METHOD: Using rheumatoid arthritis (RA) as an exemplar disease, twenty-eight articles were manually translated into a nine-dimensional categorical variable of medical socio-anthropological relevance, relating in particular (but not only) to legitimacy, temporality and spatialization. This digitalized picture (9 x 28 table) of the medical discourse was further analyzed by simple automated learning approaches to identify differences and highlight commonalities among the biomedical categories. RESULTS: Interpretation of these results provides original insights, including suggestions to: empower scientific communication between unstandardized approaches and basic biology; promote the repurposing of non-pharmacological therapies to enhance robustness of experimental approaches; and align the spatial representation of diseases and therapies in pharmacology to effectively embrace the systemic approach promoted by modern personalized and preventive medicines. We hope this original work can expand and foster interdisciplinarity among public health stakeholders, ultimately contributing to the achievement of SDG3.

Secondary infections worsen the outcome of COVID-19 in patients with hematological malignancies: A report from the ITA-HEMA-COV.

The impact of secondary infections (SI) on COVID-19 outcome in patients with hematological malignancies (HM) is scarcely documented. To evaluate incidence, clinical characteristics, and outcome of SI, we analyzed the microbiologically documented SI in a large multicenter cohort of adult HM patients with COVID-19. Among 1741 HM patients with COVID-19, 134 (7.7%) had 185 SI, with a 1-month cumulative incidence of 5%. Median time between COVID-19 diagnosis and SI was 16 days (IQR: 5-36). Acute myeloid leukemia (AML) and lymphoma/plasma cell neoplasms (PCN) were more frequent diagnoses in SI patients compared to patients without SI (AML: 14.9% vs. 7.1%; lymphoma/PCN 71.7% vs. 65.3%). Patients with SI were older (median age 70 vs. 66 years, p = 0.002), with more comorbidities (median Charlson Comorbidity Index 5 vs. 4, p < 0.001), higher frequency of critical COVID-19 (19.5% vs. 11.5%, p = 0.046), and more frequently not in complete remission (75% vs. 64.7% p = 0.024). Blood and bronchoalveolar lavage were the main sites of isolation for SI. Etiology of infections was bacterial in 80% (n = 148) of cases, mycotic in 9.7% (n = 18) and viral in 10.3% (n = 19); polymicrobial infections were observed in 24 patients (18%). Escherichia coli represented most of Gram-negative isolates (18.9%), while coagulase-negative Staphylococci were the most frequent among Gram-positive (14.2%). The 30-day mortality of patients with SI was higher when compared to patients without SI (69% vs. 15%, p < 0.001). The occurrence of SI worsened COVID-19 outcome in HM patients. Timely diagnosis and adequate management should be considered to improve their prognosis.

Neutralizing monoclonal antibodies in haematological patients paucisymptomatic for COVID-19: The GIMEMA EMATO-0321 study.

COVID-19 continues to be a relevant issue among patients with haematological malignancies (HM). Vaccines are frequently not effective in subjects on active treatment. In this multicentre retrospective study of Gruppo Italiano Malattie EMatologiche dell'Adulto (GIMEMA), we collected data from 91 paucisymptomatic HM patients treated with anti-spike neutralizing monoclonal antibodies (nMoAbs) to determine time to viral clearance, referencing it to the expected value of 28 days from an historical group of untreated paucisymptomatic patients. Secondary endpoints included rate of hospitalization, intensive care unit (ICU) admission, COVID-19 related death and safety. SARS-CoV-2 molecular swab negativity was obtained in 86 patients (95%), with a median time of 18 days (IQR 13-26; p < 0.0001). We did not find significant variations according to age, diagnosis, treatment type, vaccination status or nMoAbs type. Rate of hospitalization due to COVID-19 progression was 12% (11/91), with 2 patients (2.2%) requiring ICU admission. With a median follow-up of 2.33 months, the overall mortality was 5.5% (5/91), with 3 deaths due to COVID-19. Side effects were rare and self-limiting. Our data suggest that nMoAbs can limit the detrimental effect of immunosuppressive treatments on COVID-19 clinical progression and time to viral clearance. The original trial was registered at www.clinicaltrials.gov as #NCT04932967.

Therapeutic Management of Patients with FLT3 + Acute Myeloid Leukemia: Case Reports and Focus on Gilteritinib Monotherapy.

Acute myeloid leukemia is a malignant disorder of the bone marrow, characterized by differentiation, clonal expansion, and uncontrolled proliferation of malignant myeloid progenitor cells and by several molecular and genetic abnormalities. A mutation of FMS-like tyrosine kinase 3 gene can be observed in about one-third of cases of acute myeloid leukemia. Two FLT3 inhibitors are actually approved for FLT3 mutated acute myeloid leukemia: midostaurin, a multikinase first generation inhibitor with lower affinity for FLT3 binding, and gilteritinib fumarate, a potent second-generation inhibitor of both FLT3-ITD and TKD. Gilteritinib is a new effective and well-tolerated drug for patients with relapsing or refractory FLT3-positive acute myeloid leukemia. Thanks to its efficacy, low toxicity, its good manageability (oral formulation), this drug is suitable for all the patients, including elderly frail patient with concomitant therapies or pre-existing or underlying diseases, and can be used also in the outpatient setting, reducing risks and costs related to the hospitalization. We report and discuss seven cases of different patients with FLT3 positive acute myeloid leukemia successfully managed with gilteritinib in the real clinical practice.

Extracellular vesicles mediate the communication between multiple myeloma and bone marrow microenvironment in a NOTCH dependent way.

Multiple myeloma (MM) is an incurable hematologic neoplasm, whose poor prognosis is deeply affected by the propensity of tumor cells to localize in the bone marrow (BM) and induce the protumorigenic activity of normal BM cells, leading to events associated with tumor progression, including tumor angiogenesis, osteoclastogenesis, and the spread of osteolytic bone lesions. The interplay between MM cells and the BM niche does not only rely on direct cell-cell interaction, but a crucial role is also played by MM-derived extracellular vesicles (MM-EV). Here, we demonstrated that the oncogenic NOTCH receptors are part of MM-EV cargo and play a key role in EV protumorigenic ability. We used in vitro and in vivo models to investigate the role of EV-derived NOTCH2 in stimulating the protumorigenic behavior of endothelial cells and osteoclast progenitors. Importantly, MM-EV can transfer NOTCH2 between distant cells and increase NOTCH signaling in target cells. MM-EV stimulation increases endothelial cell angiogenic ability and osteoclast differentiation in a NOTCH2-dependent way. Indeed, interfering with NOTCH2 expression in MM cells may decrease the amount of NOTCH2 also in MM-EV and affect their angiogenic and osteoclastogenic potential. Finally, we demonstrated that the pharmacologic blockade of NOTCH activation by γ-secretase inhibitors may hamper the biological effect of EV derived by MM cell lines and by the BM of MM patients. These results provide the first evidence that targeting the NOTCH pathway may be a valid therapeutic strategy to hamper the protumorigenic role of EV in MM as well as other tumors.

Safety and Efficacy of Subcutaneous Rituximab in Previously Untreated Patients with CD20+ Diffuse Large B-Cell Lymphoma or Follicular Lymphoma: Results from an Italian Phase IIIb Study.

Subcutaneous (SC) rituximab may be beneficial in terms of convenience and tolerability, with potentially fewer and less severe administration-related reactions (ARRs) compared to the intravenous (IV) form. This report presents the results of a phase IIIb study conducted in Italy. The study included adult patients with CD20+ DLBCL or FL having received at least one full dose of IV RTX 375 mg/m2 during induction or maintenance. Patients on induction received ≥4 cycles of RTX SC 1400 mg plus standard chemotherapy and FL patients on maintenance received ≥6 cycles of RTX SC. Overall, 159 patients (73 DLBCL, 86 FL) were enrolled: 103 (54 DLBCL, 49 FL) completed induction and 42 patients with FL completed 12 maintenance cycles. ARRs were reported in 10 patients (6.3%), 3 (4.2%) with DLBCL and 7 (8.1%) with FL, all of mild severity, and resolved without dose delay/discontinuation. Treatment-emergent adverse events (TEAEs) and serious adverse events occurred in 41 (25.9%) and 14 patients (8.9%), respectively. Two patients with DLBCL had fatal events: Klebsiella infection (related to rituximab) and septic shock (related to chemotherapy). Neutropenia (14 patients, 8.9%) was the most common treatment-related TEAE. Two patients with DLBCL (2.8%) and 6 with FL (7.0%) discontinued rituximab due to TEAEs. 65.2% and 69.7% of patients with DLBCL and 67.9% and 73.6% of patients with FL had complete response (CR) and CR unconfirmed, respectively. The median time to events (EFS, PFS, and OS) was not estimable due to the low rate of events. At a median follow-up of 29.5 and 47.8 months in patients with DLBCL and FL, respectively, EFS, PFS, and OS were 70.8%, 70.8%, and 80.6% in patients with DLBCL and 77.9%, 77.9%, and 95.3% in patients with FL, respectively. The switch from IV to SC rituximab in patients with DLBCL and FL was associated with low risk of ARRs and satisfactory response in both groups. This trial was registered with NCT01987505.

Lichen planopilaris-like eruption in chronic myeloid leukemia patient during treatment with nilotinib as second-line therapy.

INTRODUCTION: Chronic myeloid leukemia (CML) is a malignant clonal disorder of hematopoietic stem cells characterized by a translocation of genetic material between chromosomes 9 and 22 resulting in the BCR-ABL fusion oncogene expression. Nilotinib is a potent second-generation tyrosine kinase inhibitor available as first line treatment. Among side effects QTc interval prolongation, pancreatitis, metabolic disorders and skin reactions are the most commonly seen. CASE REPORT: Here we describe a rare case of lichen planopilaris eruption that developed during therapy with nilotinib. MANAGEMENT & OUTCOME: Nilotinib dosage was reduced together with introduction of hydroxychloroquine with progressive improvement of alopecia. DISCUSSION: Collaboration with dermatologist and nilotinib dose reduction allowed to continue the drug maintaining major molecular response and patient's quality of life.

Genomic susceptibility in practice: The regulatory trajectory of non-rare thrombophilia (NRT) genetic tests in the clinical management of venous thrombo-embolism (VTE).

The use of individual genomic risk factors to predict the onset of common diseases is one of the main promises of personalized medicine. This paper aims to contribute to the understanding of how genetic susceptibility shapes clinical practice, by drawing on non-rare thrombophilia (NRT) tests, a common diagnostic technique for congenital predisposition to venous thromboembolism (VTE). Adopting a diachronic approach, we describe the trajectory of NRT usage and its professional regulation since the discovery of NRT variants in the mid-90s. Empirical materials combine biomedical literature, guidelines and recommendations, and interviews with key actors. We show a rapid adoption of these tests by clinicians, followed by a controversy over their clinical utility after epidemiological evaluations of NRT test demonstrated a low capacity to predict VTE in individual carriers. Indeed, alternative views on what should count as clinical utility led to heterogeneous professional regulations. Some clinicians favoured statistical and individualized predictions of risk and proposed a cessation of test prescription in the management of VTE. Others praised the context-specific clinical values of the tests that integrated their connection with aetiology and implications for prevention in healthy relatives, and therefore adopted less stringent regulatory principles. We identify three features of these genetic susceptibility tests that are central in this regulatory trajectory: two epistemological interpretations of the tests - as a molecular determinant of disease and as a multifactorial risk factor for VTE - that are alternatively aligned or opposed to each other; the connections established between different clinical contexts through test use and the correlated possibility of proposing preventive actions "for relatives; the centrality of the tests" in various clinical contexts regarding decisions about pharmacological treatment.

Eltrombopag as second line treatment in patients with primary immune thrombocytopenia: A single center real life experience.

Glucocorticoid treatment is the standard initial therapy for patients with immune thrombocytopenia (ITP). Despite a rate of 60-80% of initial remissions, only 30 to 50% of adults have a sustained response after discontinuation. Second line options are splenectomy, thrombopoietin-receptor agonists (TPO-RAs), rituximab and intravenous immunoglobulin. Third line treatments include a mix of immunosuppressive drugs (e.g. azathioprine, ciclosporin, etc.). Recently international guidelines have proposed a treatment algorithm formalizing TPO-RAs and splenectomy as second and third line respectively, confirming splenectomy as second line choice only in emergency. Here we present a single center observational retrospective study of eltrombopag as second line treatment. We evaluated 48 adult primary chronic ITP patients since 2003. Forty-four out of 48 patients received a first line treatment with glucocorticoids. Twenty-two (61%) patients needed a second line treatment: 18 received eltrombopag, 3 a second course of steroid and one patient underwent splenectomy. Every patient before starting eltrombopag or receiving splenectomy underwent bone marrow examination. Overall response rate to eltrombopag was 94% with a CR rate of 76% and a PR of 23%; only one patient was non responder, underwent splenectomy and received subsequent treatment with rituximab, romiplostim and cyclosporin obtaining CR. One patient developed an autoimmune pancytopenia about a month after starting TPO-RA and in addition to eltrombopag received steroid and rituximab with blood count improvement. After a median follow up of 21,1 months (range 0,4-64,7 months) 16 patients (89%) are still on therapy maintaining response. As regards safety, gastrointestinal side effects were rare and low grade; only one patient discontinued eltrombopag after few weeks, because of dizziness. One patient had a relapse of deep venous thrombosis while no major bleeding complications were observed. Our real-life single center experience confirms efficacy and safety of eltrombopag as second line treatment in chronic ITP patients.

JAK Inhibition with Ruxolitinib in Patients with COVID-19 and Severe Pneumonia: Multicenter Clinical Experience from a Compassionate Use Program in Italy.

Jak inhibitors are potent anti-inflammatory drugs that have the potential to dampen the hyperactive inflammatory response associated with severe COVID-19. We reviewed the clinical outcomes of 218 patients with COVID-19 hospitalized for severe pneumonia and treated with ruxolitinib through a compassionate use program. Data on the duration of treatment; outcomes at 4, 7, 14, and 28 days; oxygen support requirements; clinical status; and laboratory parameters were retrospectively collected. Overall, according to the physician evaluation, 66.5% of patients showed improvement at follow-up; of these, 83.5% showed improvement by day 7. Oxygen support status also showed improvement, and by day 7, 21.6% of patients were on ambient air, compared with 1.4% at baseline, which increased to 48.2% by day 28. Significant decreases in C-reactive protein and increases in the lymphocyte total count were already observed by day 4, which seemed to correlate with a positive outcome. At the end of the observation period, 87.2% of patients were alive. No unexpected safety findings were observed, and grade 3/4 adverse events were reported in 6.9% of patients.

Clinical Course and Risk Factors for In-Hospital Mortality of 205 Patients with SARS-CoV-2 Pneumonia in Como, Lombardy Region, Italy.

The aim of this study is to explore risk factors for in-hospital mortality and describe the effectiveness of different treatment strategies of 205 laboratory-confirmed cases infected with SARS-CoV-2 during the Lombardy outbreak. All patients received the best supportive care and specific interventions that included the main drugs being tested for repurposing to treat COVID-19, such as hydroxychloroquine, anticoagulation and antiviral drugs, steroids, and interleukin-6 pathway inhibitors. Clinical, laboratory, and treatment characteristics were analyzed with univariate and multivariate logistic regression methods to explore their impact on in-hospital mortality. Univariate analyses showed prognostic significance for age greater than 70 years, the presence of two or more relevant comorbidities, a P/F ratio less than 200 at presentation, elevated LDH (lactate dehydrogenase) and CRP (C-reactive protein) values, intermediate- or therapeutic-dose anticoagulation, hydroxychloroquine, early antiviral therapy with lopinavir/ritonavir, short courses of steroids, and tocilizumab therapy. Multivariable regression confirmed increasing odds of in-hospital death associated with age older than 70 years (OR 3.26) and a reduction in mortality for patients treated with anticoagulant (-0.37), antiviral lopinavir/ritonavir (-1.22), or steroid (-0.59) therapy. In contrast, hydroxychloroquine and tocilizumab have not been confirmed to have a significant effect in the treatment of SARS-CoV-2 pneumonia. Results from this real-life single-center experience are in agreement and confirm actual literature data on SARS-CoV-2 pneumonia in terms of both clinical risk factors for in-hospital mortality and the effectiveness of the different therapies proposed for the management of COVID19 disease.

Appraising screening, making risk in/visible. The medical debate over Non-Rare Thrombophilia (NRT) testing before prescribing the pill.

Non-rare thrombophilia (NRT) are hereditary predispositions to thromboembolism, the most severe side effect of combined hormonal contraception. In the mid-1990s, the identification of NRT stirred up a controversy over the possibility of investigating these genetic variants in women wishing to use contraception. Through a review of literature, this article reconstructs the debate over whether and how this genetic test should be prescribed as a way to reconfigure the risk visibility on pharmacological contraception. The main arguments identified concern the epidemiological, social, economic and clinical aspects of the test. In a context where the overall thrombotic risk for hormonal contraception is largely invisible, the genetic tests turn to embody the thrombotic risk itself. Those who opt for selective screening argue that a better estimation of risk implies a test prescription embed in a global medical assessment of women's individual risk. To advocates of universal or 'extended' screening, the tests are valuable tools to inform women on the thrombotic risk and, as such, appraised as a moral/legal obligation, whatever their predictive power. Risk visibility thus appears as an insightful concept to analyse a complex setting associating clinical, political, social and cultural considerations that touches upon medical power, women's responsibility and drug safety.

Nilotinib-induced bone marrow CD34+/lin-Ph+ cells early clearance in newly diagnosed CP-Chronic Myeloid Leukemia: Final report of the PhilosoPhi34 study.

Chronic Myeloid Leukemia is a clonal disorder characterized by the presence of the Ph-chromosome and the BCR-ABL tyrosine-kinase (TK). Target-therapy with Imatinib has greatly improved its outcome. Deeper and faster responses are reported with the second-generation TKI Nilotinib. Sustained responses may enable TKI discontinuation. However, even in a complete molecular response, some patients experience disease recurrence possibly due to persistence of quiescent leukemic CD34+/lin-Ph+ stem cells (LSCs). Degree and mechanisms of LSCs clearance during TKI treatment are not clearly established. The PhilosoPhi34 study was designed to verify the in-vivo activity and timecourse of first-line Nilotinib therapy on BM CD34+/lin-Ph+ cells clearance. Eighty-seven CP-CML patients were enrolled. BM cells were collected and tested for Ph+ residual cells, at diagnosis, 3, 6 and 12 months of treatment. FISH analysis of unstimulated CD34+/lin- cells in CCyR patients were positive in 8/65 (12.3%), 5/71 (7%), 0/69 (0%) evaluable tests, respectively. Per-Protocol analysis response rates were as follows: CCyR 95% at 12 months, MR4.5 31% and 46% at 12 and 36 months, respectively. An exploratory Gene Expression Profiling (GEP) study of CD34+/lin- cells was performed on 30 patients at diagnosis and after, on 79 patients at diagnosis vs 12 months of nilotinib treatment vs 10 healthy subjects. Data demonstrated some genes significantly different expressed: NFKBIA, many cell cycle genes, ABC transporters, JAK-STAT signaling pathway (JAK2). In addition, a correlation between different expression of some genes (JAK2, OLFM4, ICAM1, NFKBIA) among patients at diagnosis and their achievement of an early and deeper MR was observed.

The evolution of personalized healthcare and the pivotal role of European regions in its implementation.

Personalized medicine (PM) moves at the same pace of data and technology and calls for important changes in healthcare. New players are participating, providing impulse to PM. We review the conceptual foundations for PM and personalized healthcare and their evolution through scientific publications where a clear definition and the features of the different formulations are identifiable. We then examined PM policy documents of the International Consortium for Personalised Medicine and related initiatives to understand how PM stakeholders have been changing. Regional authorities and stakeholders have joined the race to deliver personalized care and are driving toward what could be termed as the next personalized healthcare. Their role as a key stakeholder in PM is expected to be pivotal.

First French study relative to preconception genetic testing: 1500 general population participants' opinion.

BACKGROUND: Until very recently, preconception genetic testing was only conducted in particular communities, ethnic groups or families for which an increased risk of genetic disease was identified. To detect in general population a risk for a couple to have a child affected by a rare, recessive or X-linked, genetic disease, carrier screening is proposed in several countries. We aimed to determine the current public opinion relative to this approach in France, using either a printed or web-based questionnaire. RESULTS: Among the 1568 participants, 91% are favorable to preconception genetic tests and 57% declare to be willing to have the screening if the latter is available. A medical prescription by a family doctor or a gynecologist would be the best way to propose the test for 73%, with a reimbursement from the social security insurance. However, 19% declare not to be willing to use the test because of their ethic or moral convictions, and the fear that the outcome would question the pregnancy. Otherwise, most participants consider that the test is a medical progress despite the risk of an increased medicalization of the pregnancy. CONCLUSION: This first study in France highlights a global favorable opinion for the preconception genetic carrier testing under a medical prescription and a reimbursement by social security insurance. Our results emphasize as well the complex concerns underpinned by the use of this screening strategy. Therefore, the ethical issues related to these tests include the risk of eugenic drift mentioned by more than half of the participants.

Validation of the "fitness criteria" for the treatment of older patients with acute myeloid leukemia: A multicenter study on a series of 699 patients by the Network Rete Ematologica Lombarda (REL).

OBJECTIVES: Treatment of older patients with acute myeloid leukemia (AML) is still controversial. To facilitate treatment decisions, the "fitness criteria" proposed by Ferrara et al. (Leukemia, 2013), including age > 75 years, performance status and comorbidities, were verified retrospectively in 699 patients with AML (419 de-novo, 280 secondary AML), diagnosed at 8 Hematological Centers (REL). METHODS: Patients were categorized in FIT to intensive chemotherapy (i-T) (292, 42.5%), UNFIT to i-T (289, 42.1%), or unfit even to non-intensive therapy (non i-T) (FRAIL) (105, 15.3%). Biological characteristics and treatment actually received by patients [i-T, 274 patients (39.2%); non i-T, 134 (19.2%), best-supportive care (BSC), 291 (41.6%)] were recorded. RESULTS: "Fitness criteria" were easily applicable in 98.1% of patients. Overall concordance between "fitness criteria" and treatment actually received by patients was high (79.4%), 76% in FIT, 82.7% in UNFIT and 80% in FRAIL patients. Fitness independently predicted survival (median survival: 10.9, 4.2 and 1.8 months in FIT, UNFIT and FRAIL patients, respectively; p = 0.000), as confirmed also by multivariate analysis. In FRAIL patients, survival with any treatment was no better than with BSC, in UNFIT non i-T was as effective as i-T and better than BSC, and in FIT patients i-T was better than non i-T or BSC. In addition, a non-adverse risk AML, an ECOG PS <2, and receiving any treatment other than BSC had a favorable effect on survival (p < 0.001). CONCLUSION: These simple "fitness criteria" applied at the time of diagnosis could facilitate, together with AML biologic risk evaluation, the choice of the most appropriate treatment intensity in older AML patients.

The first case of Mycobacterium vaccae sepsis in a non-Hodgkin lymphoma patient: biological understandings and clinical consequencies.

Mycobacterium vaccae is a rapidly growing nonpathogenic species of the Mycobacteriaceae family of bacteria that can cause pulmonary and disseminated disease in particular in immunocompromised individuals. Here we describe a first case of matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass-spectrometry (MS) identification of this pathogen in a patient with non-Hodgkin's lymphoma during chemoimmunotherapy salvage treatment, and its impact on clinical decision making.
