Abstract: International audience; Acute lymphoblastic leukemias (ALL) are characterized by a large number of cytogenetic abnormalities of clinical interest that require the use of several complementary techniques. Optical genome mapping (OGM) is based on analysis of ultra-high molecular weight DNA molecules that provides a high-resolution genome-wide analysis highlighting copy number and structural anomalies, including balanced translocations. We compared OGM to standard techniques (karyotyping, fluorescent in situ hybridization, single nucleotide polymorphism-array and reverse transcription multiplex ligation-dependent probe amplification) in 10 selected B or T-ALL. Eighty abnormalities were found using standard techniques of which 72 (90%) were correctly detected using OGM. Eight discrepancies were identified, while 12 additional anomalies were found by OGM. Among the discrepancies, four were detected in raw data but not retained because of filtering issues. However, four were truly missed, either because of a low variant allele frequency or because of a low coverage of some regions. Of the additional anomalies revealed by OGM, seven were confirmed by another technique, some of which are recurrent in ALL such as LMO2-TRA and MYC-TRB fusions. Despite false positive anomalies due to background noise and a case of inter-sample contamination secondarily identified, the OGM technology was relatively simple to use with little practice. Thus, OGM represents a promising alternative to cytogenetic techniques currently performed for ALL characterization. It enables a time and cost effective analysis allowing identification of complex cytogenetic events, including those currently inaccessible to standard techniques.

Abstract: The Gluthation peroxidase (GPX) enzymes are part of the protective system against lipid peroxydation that includes prevention of oxydation and reduction of already oxidized lipid through enzymatic reactions catalyzed by GSH. GPX4 is one of the five GPX able to incorporate selenium. It is also the only GPX able to directly reduce in the membrane the oxidized fatty acids and cholesterol. Recent reports identified GPX4 as the central inhibitor of ferroptosis, a process during which iron-induced peroxydation of membrane lipids causes a specific cell death that can be reverted by lipophilic antioxydants or by iron chelators. GPX4 has recently been involved during mice erythropoiesis: GPX4-/-mice present a hemolytic anemia and a high apoptotic rate in spleen erythroid progenitors. Although transcriptomics and proteomics found it expressed in human erythroid precursors, its role during human erythropoiesis has not been described. Using an in-vitroerythroid differentiation protocol from CD34+cells obtained from apheresis, we confirmed that GPX4 expression was induced at RNA and protein level during differentiation. RSL3, a specific GPX4 inhibitor, didn't affect early steps of erythropoiesis (i.eclonogenic potential and progenitor amplification) nor the early maturation of erythroid precursors (assessed by sequential CD49d/CD235/CD71 staining) but led to a significant decrease in the enucleation rate as assessed by Hoechst staining using flow cytometry (74%±9 DMSO versus 35%±6 RSL3, p Using Western Blot, we observed that RSL3 exposure induced a strong GPX4 depletion in erythroid progenitors while it didn't affect GPX1, another member of the GPX family expressed in erythroid cells. In order to confirm that enucleation defect was related to GPX4 knockdown, we used an Sh-RNA strategy that allowed a 62%±6 GPX4 decrease at RNA level and a 46%±5 at protein level. We observed a significant defect in terminal enucleation in the cells transduced with shGPX4-lentiviruses in comparison with sh-Scramble (59%±5 Sh-Scr versus 39%±6 Sh-Gpx4, p We investigated then whether GPX4-knock-down affected quantitatively or qualitatively the membrane lipid content, which was shown to be involved in the enucleation process. Addition of Cholesterol to RSL3 in the medium partially restored the enucleation rate. However, lipidomics failed to show any significant difference in the total membrane lipid content (and particularly in the cholesterol content) after RSL3 exposure in comparison to DMSO. Since cholesterol is particularly abundant in the lipid rafts, we investigated whether the lipid distribution was qualitatively altered within the cell membrane. We observed a disruption of membrane lipid rafts when cells were exposed to RSL3, as shown by a 60%±12 decrease in the mean cholera toxin fluorescence intensity. GPX4 presence in lipid rafts was confirmed using immunofluorescence showing their co-localization at cell surface in human primary erythroblasts. Since lipid rafts play a role in the contractile ring that separates pyrenocyte from reticulocyte, we evaluated the myosin-light chain phosphorylation using flow cytometry and Western Blot and found it drastically decreased in GPX4-knockdown conditions. In summary, we identified GPX4 as a new actor of human terminal erythroid differentiation, independently to its function in ferroptosis control. We described its interaction at cell surface with lipid rafts that are required for the assembly of the contractile ring and cytokinesis leading to the nucleus extrusion.

Abstract: To compare brain MRI findings in progressive multifocal leukoencephalopathy (PML) associated to rituximab and natalizumab treatments and HIV infection. In this retrospective, multicentric study, we analyzed brain MRI exams from 72 patients diagnosed with definite PML: 32 after natalizumab treatment, 20 after rituximab treatment, and 20 HIV patients. We compared T2- or FLAIR-weighted images, diffusion-weighted images, T2*-weighted images, and contrast enhancement features, as well as lesion distribution, especially gray matter involvement. The three PML entities affect U-fibers associated with low signal intensities on T2*-weighted sequences. Natalizumab-associated PML showed a punctuate microcystic appearance in or in the vicinity of the main PML lesions, a potential involvement of the cortex, and contrast enhancement. HIV and rituximab-associated PML showed only mild contrast enhancement, punctuate appearance, and cortical involvement. The CD4/CD8 ratio showed a trend to be higher in the natalizumab group, possibly mirroring a more efficient immune response. Imaging features of rituximab-associated PML are different from those of natalizumab-associated PML and are closer to those observed in HIV-associated PML. • Nowadays, PML is emerging as a complication of new effective therapies based on monoclonal antibodies. • Natalizumab-associated PML shows more inflammatory signs, a perivascular distribution “the milky way,” and more cortex involvement than rituximab- and HIV-associated PML. • MRI differences are probably related to higher levels of immunosuppression in HIV patients and those under rituximab therapy.

Abstract: IntroductionCoronavirus disease 2019 (COVID-19) can cause life-threatening acute respiratory distress syndrome (ARDS). Recent data suggest a role for neutrophil extracellular traps (NETs) in COVID-19-related lung damage partly due to microthrombus formation. Besides, pulmonary embolism (PE) is frequent in severe COVID-19 patients, suggesting that immunothrombosis could also be responsible for increased PE occurrence in these patients. Here, we evaluate whether plasma levels of NET markers measured shorty after admission of hospitalized COVID-19 patients are associated with clinical outcomes in terms of clinical worsening, survival, and PE occurrence.Patients and MethodsNinety-six hospitalized COVID-19 patients were included, 50 with ARDS (severe disease) and 46 with moderate disease. We collected plasma early after admission and measured 3 NET markers: total DNA, myeloperoxidase (MPO)–DNA complexes, and citrullinated histone H3. Comparisons between survivors and non-survivors and patients developing PE and those not developing PE were assessed by Mann–Whitney test.ResultsAnalysis in the whole population of hospitalized COVID-19 patients revealed increased circulating biomarkers of NETs in patients who will die from COVID-19 and in patients who will subsequently develop PE. Restriction of our analysis in the most severe patients, i.e., the ones who enter the hospital for COVID-19-related ARDS, confirmed the link between NET biomarker levels and survival but not PE occurrence.ConclusionOur results strongly reinforce the hypothesis that NETosis is an attractive therapeutic target to prevent COVID-19 progression but that it does not seem to be linked to PE occurrence in patients hospitalized with COVID-19.

Abstract: International audience; Introduction Acute graft-versus-host disease (aGvHD) is a major source of mortality following allogeneic hematopoietic cell transplantation (allo-HCT). Standard 1st line therapy for the treatment of aGvHD involves corticosteroids (CS). However, more than 50% of patients are refractory to CS (SR-aGvHD) and the associated mortality rate is of up to 80%. Recently, Ruxolitinib has been approved as 2nd line treatment for SR-aGvHD. However, patients with severe gastrointestinal (GI) aGvHD seem less likely to respond to Ruxolitinib and have poor outcomes with limited therapeutic options.In this context, fecal microbiotherapy has shown promising results in several pilot studies in patients with refractory GI-aGvHD. Here we report clinical outcomes from 81 patients diagnosed with SR or dependent (SD) GI-aGvHD treated with the pooled allogeneic microbiotherapy MaaT013 as part of the Early Access Program (EAP) in France.Methods 81 patients with SR/SD GI-aGvHD (Classical n=62, late onset n=12, overlap syndrome n=7) were treated with MaaT013 as part of an EAP in France. These patients had failed 1 to 6 prior systemic GvHD treatment lines (median 2; 66/81 received Ruxolitinib). Most patients had grade III-IV aGvHD (11% grade II, 51% grade III, 38% grade IV).For each patient, a total of 3 MaaT013 administrations were planned every 7 +/- 2 days. Each dose comprised 30g of feces in 150 mL of diluent, from 4 to 8 healthy donors, administered by enema (except for 1 patient by nasogastric tube).Treatment response was calculated among all treated patients based on aGvHD staging and grading at day 28 (D28) at the time of the EAP request.Results At D28, the GI-overall response rate (ORR) was 56%: 30 complete response (CR, 37%), 11 very good response rate (VGPR, 14%), 4 partial response (PR, 5%). The GI-ORR was higher in patients with lower grade aGvHD (89% in grade II, 66% in grade III, 32% in grade IV) and higher in SD versus SR patients (92% versus 49%). Including skin and liver symptoms (n=78), response rate was 49%, including 24 CR, 11 VGPR and 3 PR and inversely correlated with aGvHD initial grade (88% in grade II, 55% in grade III, 30% in grade IV).Overall survival (OS) was 51% at 6 months (M6) and 39% at M12. The median follow-up among surviving patients was 355 days (range, 53-731). OS was significantly higher in patients achieving at least GI-PR at D28 (Responder, R; n=45) compared to patients in treatment failure (Non-responder, NR; n=35): 69% versus 28% at M6, 59% versus 14% at M12, respectively. Median survival duration in R was 451 days versus 32 days in NR.Interestingly, aGvHD response was improved in the subgroup of 31 patients previously treated with Ruxolitinib as 2nd line and MaaT013 as 3rd line (65% D28 GI-ORR, OS M6 55% and 49% M12 and 74% versus 15% at M6 and 74% versus 0% at M12 for R and NR respectively).MaaT013 displayed a good overall safety profile in the EAP population: 20 pharmacovigilance cases were reported in 18 patients: sepsis in 11 patients, C. difficile colitis in 2, E. coli osteoarthritis in 1, G. silvicola in stools from 1, P. aeruginosa sinusitis in 1, appearance of air bubbles in the mesorectum in 1, respiratory distress in 1. No pathogen transmission was reported. In 2 patients, non-pathogenic commensal bacteria isolated following infectious events were detected in the administered MaaT013 batch. Causality could not be formally excluded in these cases.The overall incidence of bacteremia (14%) remains low, compared to an incidence of 31% to 74% in bloodstream infections reported in patients with GI-aGvHD. This suggests that fecal microbiotherapy may have a protective effect on bacterial translocation, but this needs to be confirmed in further clinical trials.47 deaths have been reported; the cause of which was GvHD in 21 patients, severe infection in 13, relapse of underlying malignancy in 6, COVID-19 in 3, hemorrhage during surgery in 1, neurological complications post allo-HCT in 1, and cardiac arrest in 2 patients. No causality link with MaaT013 administration has been identified.Conclusion Overall, EAP clinical data showed that MaaT013 was safe and effective for the treatment of SR/SD-GI-aGvHD especially in patients having previously received ruxolitinib. Interestingly, GI-response to aGvHD correlates with increased OS, suggesting a strong favorable benefit-risk profile for MaaT013. A Phase 3 trial is currently ongoing to confirm these results in ruxolitinib-refractory patients (NCT04769895).

Abstract: International audience; Hereditary xerocytosis is a dominantly inherited red cell membrane disorder caused in most cases by gain-of-function mutations in PIEZO1, encoding a mechanosensitive ion channel that translates a mechanic stimulus into calcium influx. We found that PIEZO1 was expressed early in erythroid progenitor cells, and investigated whether it could be involved in erythropoiesis, besides having a role in the homeostasis of mature red cell hydration. In UT7 cells, chemical PIEZO1 activation using YODA1 repressed glycophorin A expression by 75%. This effect was PIEZO1-dependent since it was reverted using specific short hairpin-RNA knockdown. The effect of PIEZO1 activation was confirmed in human primary progenitor cells, maintaining cells at an immature stage for longer and modifying the transcriptional balance in favor of genes associated with early erythropoiesis, as shown by a high GATA2/GATAI ratio and decreased alpha/beta-globin expression. The cell proliferation rate was also reduced, with accumulation of cells in G0/G1 of the cell cycle. The PIEZO1-mediated effect on UT7 cells required calcium-dependent activation of the NFAT and ERK1/2 pathways. In primary erythroid cells, PIEZO1 activation synergized with erythropoietin to activate STATS and ERK, indicating that it may modulate signaling pathways downstream of erythropoietin receptor activation. Finally, we studied the in-vitro erythroid differentiation of primary cells obtained from 14 PIEZO1-mutated patients, from 11 families, carrying ten different mutations. We observed a delay in erythroid differentiation in all cases, ranging from mild (n=3) to marked (n=8). Overall, these data demonstrate a role for PIEZO1 during erythropoiesis, since activation of PIEZO1 both chemically and through activating mutations - delays erythroid maturation, providing new insights into the pathophysiology of hereditary xerocytosis.

Abstract: IF 15.132 (2017); International audience; The introduction of novel agents has led to major improvements in clinical outcomes for patients with multiple myeloma. To shorten evaluation times for new treatments, health agencies are currently examining minimal residual disease (MRD) as a surrogate end point in clinical trials. We assessed the prognostic value of MRD, measured during maintenance therapy by next-generation sequencing (NGS). MRD negativity was defined as the absence of tumor plasma cell within 1 000 000 bone marrow cells (

Abstract: International audience; Objectives: To compare brain MRI findings in progressive multifocal leukoencephalopathy (PML) associated to rituximab and natalizumab treatments and HIV infection.Materials and methods: In this retrospective, multicentric study, we analyzed brain MRI exams from 72 patients diagnosed with definite PML: 32 after natalizumab treatment, 20 after rituximab treatment, and 20 HIV patients. We compared T2- or FLAIR-weighted images, diffusion-weighted images, T2*-weighted images, and contrast enhancement features, as well as lesion distribution, especially gray matter involvement.Results: The three PML entities affect U-fibers associated with low signal intensities on T2*-weighted sequences. Natalizumab-associated PML showed a punctuate microcystic appearance in or in the vicinity of the main PML lesions, a potential involvement of the cortex, and contrast enhancement. HIV and rituximab-associated PML showed only mild contrast enhancement, punctuate appearance, and cortical involvement. The CD4/CD8 ratio showed a trend to be higher in the natalizumab group, possibly mirroring a more efficient immune response.Conclusion: Imaging features of rituximab-associated PML are different from those of natalizumab-associated PML and are closer to those observed in HIV-associated PML.

Abstract: Gardos channelopathy (Gardos-HX) or type 2 stomatocytosis/xerocytosis is a hereditary hemolytic anemia due to mutations in the KCNN4 gene. It is rarer than inherited type 1 xerocytosis due to PIEZO1 mutations (Piezo1-HX) and its diagnosis is difficult given the absence of a specific clinical or biological phenotype. We report here that this diagnosis can be sped up using red blood cell (RBC) indices performed on an ADVIA 2120 (Siemens®) analyzer, which measures reticulocyte mean corpuscular volume (rMCV) and mean corpuscular hemoglobin concentration (rMCHC). We studied reticulocyte indices in 3 new and 12 described patients (8 families) with Gardos-HX, 11 subjects presented the recurrent p.Arg352His mutation, 4 cases (two families) carried a private KCNN4 mutation. They were compared to 79 described patients (49 families) with Piezo1-HX. Surprisingly, in Gardos-HX cases, rMCV revealed to be smaller than MCV and rMCHC higher than MCHC, in contrast with normal or Piezo1-HX RBC. Consequently, ΔMCV (rMCV-MCV) was −0.9 ± 5 fL vs. 19.8 ± 3 fL (p < 0.001) in Gardos compared with Piezo1-HX and ΔMCHC (rMCHC-MCHC) was 18.7 ± 13 vs. −50 ± 8.7 g/L (p < 0.001). A threshold of 8.6 fL for ΔMCV and −5.5 g/L for ΔMCHC could discriminate between Gardos and Piezo1-HX with 100% sensitivity and specificity, regardless of age, mutation or splenectomy status. Consequently, we showed that reticulocytes indices are useful to suggest Gardos-HX on blood count results, allowing to rapidly target these patients for gene analysis. In addition, these parameters may prove useful as a ‘functional tool’ in interpreting new KCNN4 variants.

Abstract: Acute lymphoblastic leukemias (ALL) are characterized by a large number of genetic abnormalities of prognostic and theranostic interest. Their detection requires the use of several conventional and molecular cytogenetic techniques in order to establish the most exhaustive genetic profile: conventional karyotype, FISH, SNP-Array and RT-MLPA for detection of fusion transcripts. Optical genome mapping technique is based on analysis of ultra-high molecular weight DNA (UHMW: 150 kbp-2.5 Mbp). It allows an automatic, high resolution, genome-wide detection of structural anomalies, including balanced translocations and copy number anomalies, making this technology a promising tool in ALL. However, very few data are available in ALL so far. Our objective was to compare optical mapping (Bionano Genomics) to standard techniques performed routinely (combination of karyotype, FISH, SNP-array and RT-MLPA) in 10 selected B or T-ALL patients carrying at least one major genetic abnormality including t(10;14) TLX1-TRA, t(9;22) BCR-ABL1 (e1a2 and e14a2 transcripts), t(10;11) MLLT10-PICALM, t(11;19) KMT2A-MLLT1, typical hyperdiploid profile, iAMP21, SET-NUP214 fusion, various deletions involving CDKN2A/CDKN2B, IKZF1, PAX5, PTEN, ERG and FBXW7. Abnormalities on SNP-array were retained when allele fraction was > 10% and larger than 1Mbp or > 20 kbp and involving one of the 186 genes defined as potentially relevant in leukemogenesis. A total of 79 anomalies meeting these criteria in SNP-array, and/or found by other standard techniques were identified (45 deletions, 16 whole chromosome gains, 10 duplications or partial gains, and 8 translocations). Bone marrow DMSO pellets from the 10 patients, all treated at the CHU Amiens-Picardie, were used for this study. The UHMW DNA extraction technique provided molecules with an average N50 (≥ 150 kbp) of 286 kbp, and an average coverage of 339x. Direct imaging of the DNA molecules was performed on the Bionano Saphyr system and structural variants were automatically detected using the Rare Variant Pipeline. Abnormalities analysis was blindly performed by two independent operators on the Bionano Access software (v 1.5.2.), one cytogeneticist with no training in optical mapping (operator 1) and the other optical mapping technician without training in cytogenetics (operator 2). Among the 79 relevant anomalies, 72 (91.1%) were found by operator 1 and 71 (89.9%) by operator 2. All (8/8) translocations, 43/45 (95.6%) of deletions, 8/10 (80%) of gains were found by both operators whereas 13/16 (81.25%) and 12/16 (75%) of chromosomal gains were found by operator 1 and 2 respectively. Concerning the 8 discrepancies between optical mapping and standard techniques, 4 of them were filtering issues. Three were low allelic frequency large gains clearly visible in raw data but rejected by software's CNV filters, totally, or partially for a trisomy 3 that caused the discrepancy between the two observers. The fourth was a deletion of VPREB1 gene, erroneously eliminated by operators because included in recurrent deletion zones of IGL locus. The 4 others discrepancies were non detected anomalies. Two of them were copy number variations in Xp22.33 (pseudoautosomal region), a non-covered area with the optical mapping technology, one of which was a P2RY8-CRLF2 fusion. Another sub-clonal gain (trisomy 21) found by karyotype and FISH (quantified at 7% of all nuclei) but not by SNP-array, was missed, even in raw data. The last was a near-tetraploid subclone, found only on karyotype, that might be strictly tetraploid and by definition undetectable by quantitative techniques. Interestingly, new anomalies, not detected by standard techniques, were revealed, including a translocation t(11;14)(p13;q11.2) LMO2-TRA, a translocation with inversion t(7;8)(q34;q24.1) TRB-MYC and a translocation t(14;20)(q32.33;q13.13) IGH-CEBPB. At last, in 3 cases, unidentified complex rearrangements by cytogenetics could be resolved using optical mapping. Thus, optical mapping represents an innovative, time and cost effective alternative to the different cytogenetic techniques currently performed routinely for ALL genetic characterization. It enables identification of complex cytogenetic events, including those currently inaccessible to standard techniques such as chromotripsis or certain complex translocations.

Abstract: BackgroundPrimary central nervous system lymphoma (PCNSL) is a rare form of extra-nodal non-Hodgkin lymphoma. PCNSL is a distinct subtype of non-Hodgkin lymphoma, with over 95% of tumors belonging to the diffuse large B-cell lymphoma (DLBCL) group. We have conducted a genome-wide association study (GWAS) on immunocompetent patients to address the possibility that common genetic variants influence the risk of developing PCNSL.MethodsWe performed a meta-analysis of 2 new GWASs of PCNSL totaling 475 cases and 1134 controls of European ancestry. To increase genomic resolution, we imputed >10 million single nucleotide polymorphisms using the 1000 Genomes Project combined with UK10K as reference. In addition we performed a transcription factor binding disruption analysis and investigated the patterns of local chromatin by Capture Hi-C data.ResultsWe identified independent risk loci at 3p22.1 (rs41289586, ANO10, P = 2.17 × 10−8) and 6p25.3 near EXOC2 (rs116446171, P = 1.95 x 10−13). In contrast, the lack of an association between rs41289586 and DLBCL suggests distinct germline predisposition to PCNSL and DLBCL. We found looping chromatin interactions between noncoding regions at 6p25.3 (rs11646171) with the IRF4 promoter and at 8q24.21 (rs13254990) with the MYC promoter, both genes with strong relevance to B-cell tumorigenesis.ConclusionTo our knowledge this is the first study providing insight into the genetic predisposition to PCNSL. Our findings represent an important step in defining the contribution of common genetic variation to the risk of developing PCNSL.

Abstract: Background : Patients with acute myeloid leukemia in relapse or refractory to induction therapy have dismal prognosis. Response rates to common salvage regimens are low and allogenic hematopoietic stem cell transplantation is the only curative option. Several studies have demonstrated that salvage chemotherapy with sequential conditioning could reduce leukemia relapse risk with an acceptable toxicity profile for unfavorable acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). [1] Therefore, we decided to assess this procedure in our center at Amiens University Hospital. Methods We conducted a monocentric retrospective study, including 53 patients aged over 18 years undergoing a hematopoietic stem cell transplant (HSCT) with sequential conditioning between January 2012 and December 2018, for relapse/refractory AML or high risk MDS. 44 (83%) patients received sequential conditioning containing clofarabine (SET-RIC) or Amsacrine (FLAMSA) and 9 (17%) thiotepa based (TEC-RIC) with post-transplant cyclophosphamide for mismatched donors. Patients who were GVHD free after immunosuppressors withdrawal received immunomodulation as relapse prevention with azacytidine 37.5mg/m²/day 5 days every 4 weeks for 12 cycles with 3 donor lymphocyte infusions (DLI) alterned between azacytidine cycles. Results The median age was 52 years (range 18-70). Before conditioning, 48 patients had unfavorable AML with ELN intermediate score refractory to at least one course of induction therapy or in relapse, or unfavorable ELN score; 5 patients had high risk MDS with complex karyotype. 32 patients (60,5%) had active disease and 21 (39,5%) were in complete remission (CR) including 12 with positive MRD. 13 (24,5%) patients had HLA-identical sibling donors, 27 (51%) match unrelated donors (MUD), 4 (7,5%) mismatch unrelated donors (MMD) and 9 (17%) haploidentical donors. Majority of patients (90,5%) received peripheral blood stem cell (PBSC) PBSC with median CD34+ count of 7,94.106/kg (1,84-8,44). Acute GvHD prophylaxis with Ciclosporin A, in combination with Mycophenolate mofetil for MUD/MMR/Haplo, was withdrawal with a median time of 90 days. With a median follow-up of 40 months, overall survival (OS) at 1 and 2 years was 68% and 52%. Median OS was 18,7 months (0-72,4 months) and median disease free survival (DFS) was 14,9 months (0-72,4 months). 17 patients (32%) experienced relapse after HSCT with a median time from HSCT to relapse of 6 months (1-35 months). 22 (41,5%) of patients presented with grade I-II acute graft versus host disease (GVHD) and 6 (11,3%) with grade III IV aGVHD . GVHD free relapse free survival (GRFS) at 1 and 2 years was 53% and 34,2%. One-year cumulative incidence of disease related death and non-relapse mortality was 12,6% and 17% respectively. 19 patients received immunomodulation with 5 Azacitidine and DLI if no GVHD occurred within day 120. OS was 79 % in the 19 patients receiving DLI. In univariate analysis immunomodulation post HSCT (Figure 1) was significantly associated with overall survival and leukemia free survival (p=0,0164 and p=0,0359 respectively) but not the disease status before HSCT (p=0,7). Immunomodulation administration with azacytidine and DLI was not significantly associated with cGVHD occurrence (p=0.31). Benefit of immunomodulation OS persisted in multivariate analysis (p=0.0284). Conclusion: Sequential conditioning regimen on refractory AML with secondary immunomodulation with azacytidine and DLI shows very good results with an acceptable toxicity profile in unfavorable AML. We achieve very good OS and DFS whatever disease status before HSCT. GRFS is also encouraging comparing to previously report datas [1].

Abstract: International audience; We present results of a prospective, multicenter, phase II study evaluating rituximab, bendamustine, bortezomib and dexamethasone as first-line treatment for patients with mantle cell lymphoma aged 65 years or older. A total of 74 patients were enrolled (median age, 73 years). Patients received a maximum of six cycles of treatment at 28-day intervals. The primary objective was to achieve an 18-month progression-free survival rate of 65% or higher. Secondary objectives were to evaluate toxicity and the prognostic impact of mantle cell lymphoma prognostic index, Ki67 expression, [18F]fluorodeoxyglucose-positron emission tomography and molecular minimal residual disease, in peripheral blood or bone marrow. With a median follow-up of 52 months, the 24-month progression-free survival rate was 70%, hence the primary objective was reached. After six cycles of treatment, 91% (54/59) of responding patients were analyzed for peripheral blood residual disease and 87% of these (47/54) were negative. Four-year overall survival rates of the patients who did not have or had detectable molecular residual disease in the blood at completion of treatment were 86.6% and 28.6%, respectively (P

Abstract: Mantle-cell lymphoma is generally incurable. Despite high rates of complete response after initial immunochemotherapy followed by autologous stem-cell transplantation, patients have relapses. We investigated whether rituximab maintenance therapy at a dose of 375 mg per square meter of body-surface area administered every 2 months for 3 years after transplantation would prolong the duration of response.In a phase 3 trial involving 299 patients who were younger than 66 years of age at diagnosis, we randomly assigned 240 patients to receive rituximab maintenance therapy or to undergo observation after autologous stem-cell transplantation (120 patients per group); 59 patients did not undergo randomization. The primary end point was event-free survival (with an event defined as disease progression, relapse, death, allergy to rituximab, or severe infection) after transplantation among patients who underwent randomization.After four courses of immunochemotherapy induction (rituximab, dexamethasone, cytarabine, and a platinum derivative [R-DHAP]), the overall response rate was 89%, and the complete response rate 77%. Transplantation was performed in 257 patients. The median follow-up from randomization after transplantation was 50.2 months (range, 46.4 to 54.2). Starting from randomization, the rate of event-free survival at 4 years was 79% (95% confidence interval [CI], 70 to 86) in the rituximab group versus 61% (95% CI, 51 to 70) in the observation group (P=0.001). The rate of progression-free survival at 4 years was 83% (95% CI, 73 to 88) in the rituximab group versus 64% (95% CI, 55 to 73) in the observation group (P0.001). The rate of overall survival was 89% (95% CI, 81 to 94) in the rituximab group versus 80% (95% CI, 72 to 88) in the observation group (P=0.04). According to a Cox regression unadjusted analysis, the rate of overall survival at 4 years was higher in the rituximab group than in the observation group (hazard ratio for death, 0.50; 95% CI, 0.26 to 0.99; P=0.04).Rituximab maintenance therapy after transplantation prolonged event-free survival, progression-free survival, and overall survival among patients with mantle-cell lymphoma who were younger than 66 years of age at diagnosis.

Abstract: International audience; Converging sources of evidence point to a role for inflammation in the development of depression, fatigue and cognitive dysfunction. More precisely, the tryptophan (TRP) catabolism is thought to play a major role in inflammation-induced depression. Mastocytosis is a rare disease in which chronic symptoms, including depression, are related to mast cell accumulation and activation. Our objectives were to study the correlations between neuropsychiatric features and the TRP catabolism pathway in mastocytosis in order to demonstrate mast cells' potential involvement in inflammation-induced depression. Fifty-four patients with mastocytosis and a mean age of 50.1 years were enrolled in the study and compared healthy age-matched controls. Depression and stress were evaluated with the Beck Depression Inventory revised and the Perceived Stress Scale. All patients had measurements of TRP, serotonin (5-HT), kynurenine (KYN), indoleamine 2,3-dioxygenase 1 (IDO1) activity (ratio KYN/TRP), kynurenic acid (KA) and quinolinic acid (QA). Patients displayed significantly lower levels of TRP and 5-HT without hypoalbuminemia or malabsorption, higher IDO1 activity, and higher levels of KA and QA, with an imbalance towards the latter. High perceived stress and high depression scores were associated with low TRP and high IDO1 activity. In conclusion, TRP metabolism is altered in mastocytosis and correlates with perceived stress and depression, demonstrating mast cells' involvement in inflammation pathways linked to depression.

Abstract: Background. The combination of pomalidomide and low-dose dexamethasone (Pom-Dex) has been proven effective and safe in patients with end-stage relapsed/refractory multiple myeloma (RRMM), otherwise characterized by a very poor outcome and short survival of less than a year. However, multiple myeloma remains incurable and relapses are inevitable even with pomalidomide-based regimen. It is thought that patients are back to unmet medical need after pomalidomide exposure, although the outcome after pomalidomide remains unknown. We sought to analyse the line of therapy in RRMM after Pom-Dex treatment, the response to further treatment line and survival post pomalidomide era. Methods. We included 134 patients from the 2 IFM studies (IFM2009-02 in end stage RRMM, n=84, median therapy 5 lines and IFM2010-02 in del17p and/or t(4;14) RRMM, n=50, median therapy 2 lines) treated with Pom-Dex. In both studies, patients received pomalidomide (oral 4mg daily) given either 21 days out of 28 or continuous and dexamethasone (oral 40mg weekly, but 20mg if >75 years old in the IFM 2010-02), given until progression. Overall, 95/135 patients (70%) received further therapy post Pom-Dex, 57/84 (68%) and 38/50 (76%) in IFM2009-02 and IFM2010-02 studies, respectively; the remaining patients had palliative care. Results. As a whole for the 95 patients, the median age was 60 (range 31-82), the M/F ratio was 1.5, t(4;14) was observed in 26/50 (52%) and del17p in 14/47 (30%). The post Pom-Dex regimens were very diverse, and varied significantly across the 2 trials; however, the regimens contained alkylating agents in 54% and 60% of patients in IFM2009-02 and IFM2010-02, respectively. The most prescribed alkylator was cyclophosphamide (60%) in IFM2010-02 while similar prescription of cyclophosphamide and bendamustine was observed in about 40% of patients in the IFM2009-02 study (p=0.032). Alkylating agents were administered primarily in a 3 drugs-based combination (or more) in IFM2010-02, 70%, versus in combination solely to dexamethasone for most patients in IFM2009-02, 60% (p=0.034). Amongst the combinations of alkylating agents, novel agents were considered in 55% versus 17.5% in the 2 studies, as expected considering that IFM2010-02 included patients exposed but not refractory to lenalidomide, while IFM2009-02 recruited essentially patients double refractory to lenalidomide and bortezomib (p When no alkylating agent was used, bortezomib plus dexamethasone, dexamethasone alone, or clinical trials were favoured, the latter in a lesser instance. An intensification was proposed in 8% of patients (n=8), with allogeneic transplantation in 3 patients. 27% and 29% responded to the post Pom-Dex regimen, with an extra 35% and 34% having stable disease in the 2 studies, respectively. With a median follow-up of 49 months (IFM2009-02) and 24 months (IFM2010-02), 77% and 52% of patients have died. The median PFS on Pom-Dex was approximately 5 months (CI95% 2.5;6.5) across the studies, with 20% of patients free of relapse beyond a year, similar to the post Pom-Dex phase, 5 months (2.9;7.0) and 4 months (2.2;5.7) in 2010-02 and 2009-02, with 29% and 13% of patients progression-free beyond one year, respectively. Importantly, the median OS of IFM2009-02 study (end stage RRMM, median 5 lines) for patients that had a post pomalidomide regimen was 20 months (14;26), with 30% of patients beyond 3 years, versus 13 months for the study as a whole (Leleu et al. Blood 2013) including patients considered in palliative care after Pom-Dex was stopped. This difference was not observed in IFM2010-02 to the same extent, in patients treated earlier with Pom-Dex but characterized with poor risk cytogenetic features, del17p and/or t(4;14), median OS of 14 months (9;18) across the 2 subgroups versus a median OS of 12 months and 9.8 months for the 2 subgroups in the study as a whole (Leleu et al. Blood 2015). Conclusion. Pom-Dex changed the paradigm in advanced RRMM with a prolonged PFS that translated into a prolonged OS. Importantly, OS was further improved when patients were offered a post pomalidomide therapy particularly in advanced RRMM with no poor risk cytogenetic features. Future studies might confirm the survival impact of pomalidomide used earlier in the disease course.

Abstract: Autologous stem cell transplantation (ASCT) as first-line therapy for follicular lymphoma (FL) remains controversial. The multicenter study randomized 172 patients with untreated FL for either immunochemotherapy or high-dose therapy (HDT) followed by purged ASCT. Conditioning was performed with total body irradiation (TBI) and cyclophosphamide. The 9-year overall survival (OS) was similar in the HDT and conventional chemotherapy groups (76% and 80%, respectively). The 9-year progression-free survival (PFS) was higher in the ASCT than the chemotherapy group (64% vs 39%; P = .004). A PFS plateau was observed in the HDT group after 7 years. On multivariate analysis, OS and PFS were independently affected by the per-formance status score, the number of nodal areas involved, and the treatment group. Secondary malignancies were more frequent in the HDT than in the chemotherapy group (6 secondary myelodysplastic syndrome/acute myeloid leukemia and 6 second solid tumor cancers vs 1 acute myeloid leukemia, P = .01). The occurrence of a PFS plateau suggests that a subgroup of patients might have their FL cured by ASCT. However, the increased rate of secondary malignancies may discourage the use of purged ASCT in combination with TBI as first-line treatment for FL. This trial has been registered with ClinicalTrials.gov under identifier NCT00696735.

Abstract: International audience; Background: Cell therapy has been proposed as a salvage limb procedure in critical limb ischemia (CLI). Autologous cell therapy products (CTP) are obtained from patients with advanced peripheral arterial disease to be injected at the site of ischemia. Thrombogenicity of CTPs has not yet been assessed. The objectives were: 1) to assess thrombotic risk in candidates for cell therapy, 2) to evaluate two different CTPs in terms of thrombogenic potential, and 3) to evaluate clinical thrombotic events.Study design and methods: In this ancillary study of a Phase I and II clinical trial, bone marrow (BM)-CTPs (n = 20) and CTPs obtained by cytapheresis (peripheral blood [PB]-CTPs; n = 20) were compared. Inflammatory and coagulation markers were measured at baseline and 24 hours after CTP implantation. CTP cell content and tissue factor (TF) expression (mRNA and protein) were analyzed. Thrombin generation assessed CTP-related thrombogenicity.Results: All patients presented cardiovascular risk factors. At baseline, the patients' biologic profile was characterized by high levels of fibrinogen, C-reactive protein (CRP), D-dimer, interleukin (IL)-6, and plasmatic TF, whereas IL-10 was low. Although different in terms of cell composition, both BM- and PB-CTPs support low thrombin generation. Twenty-four hours after implantation, biologic markers remained stable in the PB-CTP group, except for IL-6. In the BM-CTP group, a significant increase of IL-6 but also of CRP and D-dimer was observed. Clinically, one single patient developed deep vein thrombosis 24 hours after the implantation of autologous PB-CTP.Conclusion: CTPs supported low thrombin generation and were well tolerated after calf implantation.

Abstract: International audience; We report our experience on bendamustine and rituximab (BR) combination in 26 patients with chronic lymphocytic leukemia (CLL) complicated by autoimmune hemolytic anemia (AIHA). At the time of BR initiation, 88% of the patients had already been treated for AIHA and CLL was progressive regardless of AIHA in all patients but one. Overall response rates were 81% for AIHA and 77% for CLL. Median time to next treatment was 28.3 months and 26.2 months for AIHA and CLL, respectively. BR therapy may represent a good and safe therapeutic option in this setting where adequate control of CLL seems important for long-term AIHA response. Am. J. Hematol. 90:204–207, 2015.

Abstract: International audience; Mastocytosis is a rare and chronic disease with phenotypes ranging from indolent to severe. Prognosis for this disease is variable and very few biomarkers to predict disease evolution or outcome are currently known. We have performed comprehensive screening in our large cohort of mastocytosis patients for mutations previously found in other myeloid diseases and that could serve as prognostic indicators. KIT, SRSF2-P95 and TET2 mutations were by far the most frequent, detected in 81%, 24% and 21% of patients, respectively. Where TET2 and SRSF2-P95 mutation both correlated with advanced disease phenotypes, SRSF2-P95 hotspot mutation was found almost exclusively in patients diagnosed with associated clonal hematologic non-mast cell disease. Statistically, TET2 and SRSF2-P95 mutations were highly associated, suggesting a mechanistic link between these two factors. Finally, analysis of both clonal and sorted cell populations from patients confirms the presence of these mutations in the mast cell component of the disease, suggests an ontological mutation hierarchy and provides evidence for the expansion of multiple clones. This highlights the prognostic potential of such approaches, if applied systematically, for delineating the roles of specific mutations in predisposing and/or driving distinct disease phenotypes.

Abstract: Background. Primary bone lymphoma (PBL) is a rare entity that has only been reviewed in one prospective and small retrospective studies, from which it is difficult to establish treatment guidelines. We prospectively evaluated high-dose or conventional anthracycline-cyclophosphamide dose and radiotherapy for PBL.Patients and Methods. The GOELAMS prospective multicenter study (1986–1998) enrolled adults with localized high-grade PBL according to age and performance status (PS). Patients Results. Among the 26 patients included (VCAP: 19; VCEP-bleomycin: 7), 39% had poor PS ≥2. With a median follow-up of 8 years, overall survival, event-free survival, and relapse-free survival were 64%, 62%, and 65%, respectively, with no significant difference between treatment groups. Poor PS was significantly associated with shorter OS and EFS.Conclusions. Our results confirm the efficacy of our age-based therapeutic strategy. High-doses anthracycline-cyclophosphamide did not improve the outcome. VCEP-bleomycin is effective and well tolerated for old patients. The intensification must be considered for patients with PS ≥2, a poor prognostic factor.

Abstract: International audience; Diagnosis of blastic plasmacytoid dendritic cell neoplasm (BPDCN) or plasmacytoid dendritic cell leukemia (pDCL) is mainly based on immunophenotypical characterization of leukemic cells in blood or bone marrow samples. We tested by flow cytometry intracellular expression of the proto-oncogene T-cell leukemia 1 (TCL1), as well as membrane and intracellular expression of immunoglobulin-like transcript 7 (ILT7) in 21 pDCL samples and 61 non-pDC acute leukemia samples [i.e., 14 B-acute lymphoblastic leukemia (B-ALL), 9 T-ALL and 38 acute myeloid leukemia (AML)]. TCL1 is highly expressed in all pDCL samples while at a statistically lower level in all B-ALL and 34% of AML. Statistical analysis shows that intensity of TCL1 expression is a good marker for differential diagnosis of pDCL versus other acute leukemia (area under the receiver-operating characteristic curve, [AUC]: 0.96). By contrast, ILT7 positivity is limited to few pDCL samples and cannot be useful for diagnosis purpose. In conclusion, high intracellular intensity of TCL1 expression is currently the best marker for pDC lineage assignment by flow cytometry, which is particularly useful to distinguish pDCL from CD4(+) CD56(+/-) undifferentiated or monoblastic acute leukemia. Thus, intracellular TCL1 detection should be included in acute leukemia diagnosis panels used in hematology laboratories. © 2012 International Society for Advancement of Cytometry.

Abstract: International audience; Peripheral T-Cell lymphomas (PTCL) are relatively rare diseases but appear as highly aggressive and display worse remission and survival rates than B-cell lymphomas. Despite non satisfactory results with the CHOP regimen, it remains the reference front line therapy in these diseases, but has not been challenged in phase III trials. The GOELAMS group devised an alternative therapeutic schedule including Etoposide, Ifosfamide, Cisplatin alternating with Doxorubicin, Bleomycin, Vinblastin, Dacarbazine (VIP-reinforced-ABVD) and compared it to CHOP/21 as front-line treatment in non cutaneous PTCL. All newly diagnosed patients were eligible. The primary objective was to improve the 2-years event-free survival (EFS) rate. Secondary objectives were to compare the response rates, overall survival, and toxicities as well as identify prognostic factors. 88 patients were identified between 1996 and 2002. Both arms were well balanced for patients' characteristics in terms of histological and clinical presentation. No significant difference was observed between the two arms in terms of 2-years EFS. ALCL type and Ann Arbor stage I-II were identified as two independent favourable prognostic factors influencing survival. The VIP-rABVD regimen was not superior to CHOP/21 in term of EFS as first-line treatment of PTCL, confirming that CHOP/21 remains the reference arm in these lymphomas.

Abstract: International audience; Aldehyde dehydrogenase 1A1 (ALDH) activity is one hallmark of human bone marrow (BM), umbilical cord blood (UCB), and peripheral blood (PB) primitive progenitors presenting high reconstitution capacities in vivo. In this study, we have identified ALDH(+) cells within human skeletal muscles, and have analyzed their phenotypical and functional characteristics. Immunohistofluorescence analysis of human muscle tissue sections revealed rare endomysial cells. Flow cytometry analysis using the fluorescent substrate of ALDH, Aldefluor, identified brightly stained (ALDH(br)) cells with low side scatter (SSC(lo)), in enzymatically dissociated muscle biopsies, thereafter abbreviated as SMALD(+) (for skeletal muscle ALDH(+)) cells. Phenotypical analysis discriminated two sub-populations according to CD34 expression: SMALD(+)/CD34(-) and SMALD(+)/CD34(+) cells. These sub-populations did not initially express endothelial (CD31), hematopoietic (CD45), and myogenic (CD56) markers. Upon sorting, however, whereas SMALD(+)/CD34(+) cells developed in vitro as a heterogeneous population of CD56(-) cells able to differentiate in adipoblasts, the SMALD(+)/CD34(-) fraction developed in vitro as a highly enriched population of CD56(+) myoblasts able to form myotubes. Moreover, only the SMALD(+)/CD34(-) population maintained a strong myogenic potential in vivo upon intramuscular transplantation. Our results suggest that ALDH activity is a novel marker for a population of new human skeletal muscle progenitors presenting a potential for cell biology and cell therapy.

Abstract: We designed a randomized trial of IC with or without quinine, an agent capable of reverting the multidrug resistance (mdr) phenotype, in patients aged < or = 65 years with high risk MDS. Patients were randomized to receive Mitoxantrone 12 mg/m2/d d2-5 + AraC 1 g/m2/12 h d1-5, with (Q+) or without (Q-) quinine (30 mg/kg/day). 131 patients were included. PGP expression analysis was successfully made in 91 patients and 42 patients (46%) had positive PGP expression. In PGP positive cases, 13 of the 25 (52%) patients who received quinine achieved CR, as compared to 3 of the 17 (18%) patients treated with chemotherapy alone (p = 0.02). In PGP negative cases, the CR rate was 35% and 49%, respectively in patients who received quinine or chemotherapy alone (difference not significant). In the 42 PGP positive patients, median Kaplan-Meier (KM) survival was 13 months in patients allocated to the quinine group, and 8 months in patients treated with chemotherapy alone (p = 0.01). In PGP negative patients, median KM survival was 14 months in patients allocated to the quinine group, and 14 months in patients treated with chemotherapy alone. Side effects of quinine mainly included vertigo and tinnitus that generally disappeared with dose reduction. Mucositis was significantly more frequently observed in the quinine group. No life threatening cardiac toxicity was observed. In conclusion, results of this randomized study show that quinine increases the CR rate and survival in PGP positive MDS cases treated with IC. The fact that quinine had no effect on the response rate and survival of PGP negative MDS suggests a specific effect on PGP mediated drug resistance rather than, for instance, a simple effect on the metabolism of Mitoxantrone and/or AraC.

Abstract: International audience; ACKGROUND AND OBJECTIVES: Zeta-associated protein 70 (ZAP-70), a member of the Syk family of protein tyrosine kinases, is normally expressed in T and NK cells. While little is known about ZAP-70 expression in normal human B cells, it has been reported that ZAP-70 is expressed in a subset of patients with chronic lymphocytic leukemia (CLL) with a poor prognosis. In this study, we examined the expression and phosphorylation status of ZAP-70 in B-lineage acute lymphoblastic leukemia (Blin-ALL).DESIGN AND METHODS: First, ZAP-70 protein expression was assessed by Western blotting and flow cytometry and ZAP-70 mRNA transcripts were analyzed by reverse transcription polymerase chain reaction (RT-PCR) on human precursor B cell lines. Experiments were then carried out on cells obtained from 18 patients with Blin-ALL and from normal human bone marrow.RESULTS: ZAP-70 was constitutively expressed and phosphorylated on tyr319 in human precursor Blin-ALL cell lines as well as in primary B leukemic cells from all examined Blin-ALL patients with pro-B, pre-B and B phenotypes, but not in malignant myeloid cells. Importantly, analysis of normal human bone marrow revealed expression of ZAP-70 transcripts only in the CD34+ cell fraction (either CD19-CD10- or CD19+CD10+) but not in the CD34- cell fraction (CD19+sIgM- pre-B cells or CD19+sIgM+ immature B cells).INTERPRETATION AND CONCLUSIONS: ZAP-70 was found to be expressed in the CD34+ normal bone marrow compartment including earlier B-cell progenitors, but not in CD34- pre-B and immature B cells. By contrast, ZAP-70 was consistently expressed and phosphorylated in Blin-ALL cells. Further studies are required to determine whether ZAP-70 may play a pathophysiological role in Blin-ALL..

39. Red blood cell proteomics reveal remnant protein biosynthesis and folding pathways in PIEZO1-related hereditary xerocytosis.

Author: Caulier A, Jankovsky N, Gautier EF, El Nemer W, Guitton C, Ouled-Haddou H, Guillonneau F, Mayeux P, Salnot V, Bruce J, Picard V, and Garçon L
Abstract: Hereditary xerocytosis is a dominant red cell membrane disorder characterized by an increased leak of potassium from the inside to outside the red blood cell membrane, associated with loss of water leading to red cell dehydration and chronic hemolysis. 90% of cases are related to heterozygous gain of function mutations in PIEZO1, encoding a mechanotransductor that translates a mechanical stimulus into a biological signaling. Data are still required to understand better PIEZO1-HX pathophysiology. Recent studies identified proteomics as an accurate and high-input tool to study erythroid progenitors and circulating red cell physiology. Here, we isolated red blood cells from 5 controls and 5 HX patients carrying an identified and pathogenic PIEZO1 mutation and performed a comparative deep proteomic analysis. A total of 603 proteins were identified among which 56 were differentially expressed (40 over expressed and 16 under expressed) between controls and HX with a homogenous expression profile within each group. We observed relevant modifications in the protein expression profile related to PIEZO1 mutations, identifying two main "knots". The first contained both proteins of the chaperonin containing TCP1 complex involved in the assembly of unfolded proteins, and proteins involved in translation. The second contained proteins involved in ubiquitination. Deregulation of proteins involved in protein biosynthesis was also observed in in vitro -produced reticulocytes after Yoda1 exposure. Thus, our work identifies significant changes in the protein content of PIEZO1-HX erythrocytes, revealing a "PIEZO1 signature" and identifying potentially targetable pathways in this disease characterized by a heterogeneous clinical expression and contra-indication of splenectomy., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Caulier, Jankovsky, Gautier, El Nemer, Guitton, Ouled-Haddou, Guillonneau, Mayeux, Salnot, Bruce, Picard and Garçon.)

40. Plasma Markers of Neutrophil Extracellular Trap Are Linked to Survival but Not to Pulmonary Embolism in COVID-19-Related ARDS Patients.

Abstract: Introduction: Coronavirus disease 2019 (COVID-19) can cause life-threatening acute respiratory distress syndrome (ARDS). Recent data suggest a role for neutrophil extracellular traps (NETs) in COVID-19-related lung damage partly due to microthrombus formation. Besides, pulmonary embolism (PE) is frequent in severe COVID-19 patients, suggesting that immunothrombosis could also be responsible for increased PE occurrence in these patients. Here, we evaluate whether plasma levels of NET markers measured shorty after admission of hospitalized COVID-19 patients are associated with clinical outcomes in terms of clinical worsening, survival, and PE occurrence., Patients and Methods: Ninety-six hospitalized COVID-19 patients were included, 50 with ARDS (severe disease) and 46 with moderate disease. We collected plasma early after admission and measured 3 NET markers: total DNA, myeloperoxidase (MPO)-DNA complexes, and citrullinated histone H3. Comparisons between survivors and non-survivors and patients developing PE and those not developing PE were assessed by Mann-Whitney test., Results: Analysis in the whole population of hospitalized COVID-19 patients revealed increased circulating biomarkers of NETs in patients who will die from COVID-19 and in patients who will subsequently develop PE. Restriction of our analysis in the most severe patients, i.e., the ones who enter the hospital for COVID-19-related ARDS, confirmed the link between NET biomarker levels and survival but not PE occurrence., Conclusion: Our results strongly reinforce the hypothesis that NETosis is an attractive therapeutic target to prevent COVID-19 progression but that it does not seem to be linked to PE occurrence in patients hospitalized with COVID-19., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Prével, Dupont, Labrouche-Colomer, Garcia, Dewitte, Rauch, Goutay, Caplan, Jozefowicz, Lanoix, Poissy, Rivière, Orieux, Malvy, Gruson, Garçon, Susen and James.)

Abstract: Purpose of the Study: Atypical serum protein electrophoresis (SPE) profiles may arise in patients who received allogeneic hematopoietic stem cell transplantation (allo-HSCT), but little is known about their clinical significance. Atypical SPE combine either monoclonal and oligoclonal components, suspected on SPE and confirmed by immunofixation. The aim of the study is to analyze the incidence, the etiology and the clinical significance of atypical SPE profiles in patients who received allo-HSCT., Patients and Methods: This retrospective study enrolled 117 patients with myeloid malignancies who received an allo-HSCT between 2012 and 2018. We excluded patients with lymphoid malignancies or multiple myeloma, patients presenting atypical electrophoresis prior to transplantation and patients who died within 100 days post-transplant., Results: Atypical SPE occurred in 42.7% of patients. The cumulative incidence of atypical profiles was significantly higher in patients with acute Graft Versus Host Disease (GVHD, p = 0.019) and in patients with Cytomegalovirus (CMV) reactivation (p = 0.0017). We observed for the first time that atypical SPE profiles mostly occurred in patients transplanted from a CMV+ donor (p = 0.031). CMV reactivation preceded the occurrence of atypical SPE in the majority of patients. We show that atypical SPE delay the relapse of the underlying malignant disease (486 vs 189 days, p = 0.006), and significantly improve overall survival (OS; 33.1 months vs 28.3 months, p = 0.049). In both univariate and multivariate analyzes, the presence of an atypical SPE is the only factor that significantly improves OS., Conclusions: The occurrence of atypical SPE profiles after allo-HSCT may reflect an adapted post-transplant immune response leading to favourable outcomes., Competing Interests: Declaration of Competing Interest None., (Copyright © 2021 Elsevier Masson SAS.

Abstract: CD30 transmembrane receptor, a member of the tumor necrosis factor receptor family, is expressed in different lymphomas. Brentuximab vedotin (BV), a CD30 monoclonal antibody (Ab)-drug conjugate, is effective in CD30-positive lymphomas. However, the response to BV is not always correlated to CD30 expression detected by immunohistochemistry (IHC). The objectives of this study were to standardize and evaluate CD30 intensity by flow cytometry (FCM) in non-Hodgkin's lymphomas. Twelve centers analyzed 161 cases on standardized cytometers using normalized median fluorescence intensity (nMFI30) of three different Abs, of which one clone can recognize the same epitope as BV. FCM distinguished four groups of cases: negative group (n = 110) which showed no expression with the three clones; high positive group (n = 13) which gave nMFI30 > 5% with all tested clones; dim positive group (n = 17) which showed nMFI30 > 1% with all tested clones and <5% for at least one; discordant group (n = 21) with positive and negative expression of the different clones. In consistency with the literature, CD30 was positive in all anaplastic large cell lymphomas, in some diffuse large B-cell lymphomas (DLBCL), and in other rare lymphomas. FCM results were concordant with those of IHC in 77% of cases. Discrepancies could be explained by clones-related differences, microenvironment, or intracytoplasmic staining. Interestingly, FCM was more sensitive than IHC in 11% of cases, especially in DLBCL. Multicenter standardized FCM of specific CD30 could improve case detection and extend the treatment of BV to various CD30-positive lymphomas., (© 2020 International Clinical Cytometry Society.)

Abstract: Various predictive scores for vitamin K antagonist (VKA)-related bleeding have been developed and validated in outpatients and in patients treated for specific indications (when VKAs are used under optimal therapeutic conditions). However, there are few published data on the evaluation of bleeding risk factors in hospitalized, at-risk patients (with a high international normalized ratio [INR]) treated with VKAs. The objective of the present study was to identify the most relevant bleeding risk factors in 906 VKA-treated patients with an INR of 5 or more hospitalized in a French university medical center.Over a 2-year period, we screened all consecutive VKA-treated adults with a risk of major bleeding (defined as an INR ≥ 5 on admission). Demographic and clinical characteristics, medications, and bleeding characteristics were recorded prospectively.The overall incidence of bleeding was 26.6% (serious bleeding: 21.4%; fatal bleeding: 5.4%). An INR ≥ 8.5, a history of recent digestive tract lesions, trauma in the preceding 2 weeks, and known noncompliance were independent risk factors for bleeding and serious bleeding.Our present findings emphasize that VKAs should not be prescribed to patients with a high risk of bleeding (noncompliant patients and those with recent trauma or recent gastrointestinal lesions). It is essential to monitor the INR on a frequent basis and adjust oral anticoagulant treatment appropriately., Competing Interests: The authors have no conflicts of interest to disclose.

Abstract: Background: Cell therapy has been proposed as a salvage limb procedure in critical limb ischemia (CLI). Autologous cell therapy products (CTP) are obtained from patients with advanced peripheral arterial disease to be injected at the site of ischemia. Thrombogenicity of CTPs has not yet been assessed. The objectives were: 1) to assess thrombotic risk in candidates for cell therapy, 2) to evaluate two different CTPs in terms of thrombogenic potential, and 3) to evaluate clinical thrombotic events., Study Design and Methods: In this ancillary study of a Phase I and II clinical trial, bone marrow (BM)-CTPs (n = 20) and CTPs obtained by cytapheresis (peripheral blood [PB]-CTPs; n = 20) were compared. Inflammatory and coagulation markers were measured at baseline and 24 hours after CTP implantation. CTP cell content and tissue factor (TF) expression (mRNA and protein) were analyzed. Thrombin generation assessed CTP-related thrombogenicity., Results: All patients presented cardiovascular risk factors. At baseline, the patients' biologic profile was characterized by high levels of fibrinogen, C-reactive protein (CRP), D-dimer, interleukin (IL)-6, and plasmatic TF, whereas IL-10 was low. Although different in terms of cell composition, both BM- and PB-CTPs support low thrombin generation. Twenty-four hours after implantation, biologic markers remained stable in the PB-CTP group, except for IL-6. In the BM-CTP group, a significant increase of IL-6 but also of CRP and D-dimer was observed. Clinically, one single patient developed deep vein thrombosis 24 hours after the implantation of autologous PB-CTP., Conclusion: CTPs supported low thrombin generation and were well tolerated after calf implantation., (© 2015 AABB.)

Abstract: The prognostic value of ferritin level at diagnosis in AML patients is unknown. We studied 162 younger AML patients with intermediate-risk cytogenetics who received intensive chemotherapy. The median ferritin level at diagnosis was 633 μg/L and 128 (79%) patients had a ferritin level above the upper normal limit. Hyperferritinemia was significantly associated with a higher cumulative incidence of relapse as well as poorer disease-free and overall survival. In multivariate analysis, hyperferritinemia remained an independent poor prognosis factor. The level of ferritin at diagnosis has a major impact on relapse suggesting a link between inflammation, oxidative stress and chemoresistance in AML., (Copyright © 2015 Elsevier Ltd.

Abstract: In 1996, due to a residual risk of transfusion-transmitted virus, a circular of the French Health Authorities (DGS/DH n degrees 96-609) recommended proposing to recipients of cellular blood products a test for antibodies to human immunodeficiency virus (HIV) and for antibodies to hepatitis C virus, before and three months after transfusion. We have evaluated the application of this recommendation throughout the whole transfused population of a French Hospital over a three month period. In addition, this study allowed us to establish the vaccination status against hepatitis B virus (HBV) infection in this exposed population including transfusion and nosocomial risks. The results showed a failure in the application of the 1996 circular and confirmed the validity of the abrogation of this circular by a recent circular (11 January 2006) of the French health authorities. It also showed that only a minority of patients needing a vaccination against HBV were afforded such treatment during their hospitalization.
