Abstract
The relapse rate in antiphospholipid syndrome (APS) remains high, i.e. around 20%-21% at 5 years in thrombotic APS and 20-28% in obstetrical APS [2, 3]. Hydroxychloroquine (HCQ) appears as an additional therapy, as it possesses immunomodulatory and anti-thrombotic various effects [4-16]. Our group recently obtained the orphan designation of HCQ in antiphospholipid syndrome by the European Medicine Agency. Furthermore, the leaders of the project made the proposal of an international project, HIBISCUS, about the use of Hydroxychloroquine in secondary prevention of obstetrical and thrombotic events in primary APS. This study has been launched in several countries and at now, 53 centers from 16 countries participate to this international trial. This trial consists in two parts: a retrospective and a prospective study. The French part of the trial in thrombosis has been granted by the French Minister of Health in December 2015 (the academic trial independent of the pharmaceutical industry PHRC N PAPIRUS) and is coordinated by one of the members of the leading consortium of HIBISCUS.

Abstract
Primary antiphospholipid syndrome (PAPS) and antiphospholipid syndrome associated to lupus (SAPS) have several overlapping characteristics. As systemic manifestations are also reported in patients with PAPS, and as a subgroup of PAPS patients could evaluate to a SAPS, the differentiation between the two types of APS could be performed based on the clinical experience of the medical teams and is related to a variety of clinical, biological, histological and genetic features. Several data are available in the literature with respect to the identification of distinctive features between these two entities. However, there are some limitation in the interpretation of results issued from studies performed prior to updated Sydney criteria. Based on recent data, a certain number of features more frequent in one type of APS as compared to the other could be distinguished. The major differentiation between these two entities is genetical. New genetic data allowing the identification of specific subgroups of APS are ongoing.

Abstract
OBJECT Experimental circuits for biomaterial surface testing are frequently limited by the tested blood volume, composition of the circuit, flow conditions and the use of animal blood. This report describes an ex vivo set-up for simulated cardiopulmonary bypass with human blood perfusion. We investigated the clinical generalizability of the observed effects on hematological and metabolic parameters and the hemocompatibility of the system. METHODS The simulated cardiopulmonary bypass circuit consisted of a heparin-coated tubing system connected to an oxygenator and a venous reservoir. Normothermic flow of blood obtained from healthy donors was maintained at 2.4 L/min/m(2) by a roller pump. Heparin was dosed to obtain a target activated clotting time (ACT) ⩾500 s. Blood was drawn at baseline and 0, 10, 60 and 120 minutes following the initiation of blood flow to determine hematological and metabolic parameters and the hemocompatibility of the extracorporeal system. Data were analyzed using repeated measures ANOVA. RESULTS Two hours of blood perfusion resulted in a small, but clinically unimportant reduction in hematocrit, whereas hemoglobin levels and red blood cell, platelet and leukocyte counts remained stable. There was a significant increase in ACT throughout the experiment. While pO2 levels and the pH remained unaltered during the experiment, pCO2 values decreased from 51 ± 6 mmHg at T0 to 41 ± 3 mmHg at T120 (p<0.001). Simulated cardiopulmonary bypass induced a two-fold increase in C3a (p=0.001) while tissue factor was decreased from 44 ± 14 pg/mL at T0 to 38 ± 13 pg/mL at T120 (p=0.009). Levels of CD40L, prothrombin fragment 1+2, β-thromboglobulin and factor VIIa remained stable over time. CONCLUSION The ex vivo set-up for simulated cardiopulmonary bypass mimicked the clinical cardiosurgical setting. Exposure of fresh donor blood to the extracorporeal circuit showed a good hemocompatibility, indicated by maintained hematological parameters and a mild immune response.

Abstract
OBJECTIVES Bioactive Carmeda® heparin-coated extracorporeal circuits (ECCs) have been shown to reduce contact phase and coagulation activation during cardiopulmonary bypass (CPB). Heparin coating is therefore effective in safely reducing coagulation during routine CPB. Balance® Biosurface is a new, recently developed biopassive coating containing negatively charged sulphonated polymers. This study sought to compare the clotting activation and thromboresistance of the Balance® (B) circuit with that of the Carmeda® (C) with full-dose systemic heparin (FDH) and reduced-dose systemic heparin (RDH). METHODS This ex vivo study set-up comprising 40 experiments consisted of simplified ECC and circulation of freshly donated human blood. RDH and FDH regimens were obtained with 0.5 IU/ml and 1 IU/ml heparin administered to reach target activated clotting times (ACTs) of 250 and 500 s, respectively. The study design comprised four groups: FDH-C, FDH-B, RDH-C and RDH-B (all n = 10). Blood was sampled prior to and during the 2-h CPB. Coagulation activation was assessed (FXIIa, F1.2) and electron microscope scan imaging of oxygenators enabled determination of adhesion scores. RESULTS With a biopassive compared with bioactive surface, mean ACT was lower, regardless of the heparin regimen applied (P < 0.001), whereas the total heparin dose required to maintain ACT was above target level (P < 0.001). However, FXIIa and F1.2 values were similar in all groups throughout, as were pressure gradients among oxygenators. All groups demonstrated similar adhesion scores following ultrastructural oxygenator assessment. CONCLUSIONS In the absence of surgical-related haemostatic disturbances and based on target ACT levels under reduced- or full-dose heparin, the clotting process was similar to heparin-coated and new sulphonated polymer-coated ECC, both demonstrating similar thromboresistance.

Abstract
On the occasion of the coverage of a cervical tumefaction in a child, which led to the diagnosis of acinic cell carcinoma of ectopic salivary gland, the authors conducted a literature review of this tumour. If it is well known to pathologists when it is developed in the major or accessories salivary glands, its location within heterotopy of salivary tissue is much rarer. From a histological point of view it is difficult to distinguish, if primitive location, the occurrence of the tumour in an ectopic salivary gland, its occurrence in intra-node heterotopic salivary tissue. This distinction between glandular ectopia and intra-node heterotopia remains purely theoretical, and does not affect the therapeutic decision. This one remains empirical and discussed on a case-by-case basis for a malignant tumour that is exceptional in this location and at that age.

Abstract
We previously showed a prolonged inhibition of current-induced vasodilation (CIV) after a single oral high dose of aspirin. In this study, we tested the hypothesis of platelet involvement in CIV. Nine healthy volunteers took 75 mg aspirin/day, 98 mg of clopidogrel bisulfate/day, or placebo for 4 days. CIV was induced by two consecutive 1-min anodal current applications (0.08 mA/cm(2)) through deionized water with a 10-min interval. CIV was measured with laser Doppler flowmetry and expressed as a percentage of baseline cutaneous vascular conductance: %C(b). In a second experiment in 10 volunteers, aspirin and placebo were given as in experiment 1, but a 26-h delay from the last aspirin intake elapsed before ACh iontophoresis and postocclusive hyperemia were studied in parallel to CIV. In experiment 1, the means +/- SE amplitude of CIV was 822 +/- 314, 313 +/- 144, and 746 +/- 397%C(b) with placebo, aspirin (P < 0.05 from placebo and clopidogrel), and clopidogrel (NS from placebo), respectively. In experiment 2, CIV impairment with aspirin was confirmed: CIV amplitudes were 300 +/- 99, and 916 +/- 528%C(b) under aspirin and placebo, respectively (P < 0.05), whereas vasodilation to ACh iontophoresis (322 +/- 74 and 365 +/- 104%C(b)) and peak postocclusive hyperemia (491 +/- 137 and 661 +/- 248%C(b)) were not different between aspirin and placebo, respectively. Low-dose aspirin, even 26 h after oral administration, impairs CIV, while ACh-mediated vasodilation and postocclusive hyperemia are preserved. If platelets are involved in the neurovascular mechanism triggered by galvanic current application in humans, it is likely to occur through the cyclooxygenase but not the ADP pathway.

Abstract
Bone marrow necrosis is defined by extensive necrosis of the myeloid tissue and bone marrow stroma. Diagnosis is done on characteristic cytological pattern of the bone marrow aspiration and/or biopsy. We report two observations. The first patient, aged 75, has been hospitalized for fever, asthenia and lower back pain. An haematological malignancy was suspected after observation of a few peripheral blood blast cells, but necrosis was found on the bone marrow aspiration and could not lead to further haematological diagnosis. Within next days, the white blood cell count and the number of blasts increased, leading to the diagnosis of acute monoblastic leukaemia. A chemotherapy was started but the patient died 20 days after admission. The second patient, aged 28, has been hospitalized for severe bleeding a few days after the diagnosis of a metastatic gastric tumour. The bone marrow aspiration, made for the evaluation of a thrombocytopenia, showed a massive necrosis. The patient deceased shortly after hospitalization. According to literature, bone marrow necrosis is in most instances secondary to either an haematological malignancy (60%) or to a solid tumour (30%), but only at times observed with a non-malignant disorder. Bone pain, fever, cytopenias and elevated serum lactic dehydrogenase and alkaline phosphatase are frequently reported, but are mostly non specific of the diagnosis in these malignant conditions. Examination of the bone marrow leads to the diagnosis: cells are pycnotic, scarcely recognizable in a background of amorphous extracellular eosinophilic proteinaceous material, and histology shows disappearance of fat spaces with preservation of the bone tissue. Tissue hypoxemia due to microcirculation failure may be the main mechanism leading to the necrosis, whatever the related disorder. Supportive care together with specific therapy of the causal disease must be started promptly. The prognosis depends on the underlying illness and is generally very poor when extensive necrosis is observed.

Abstract
OBJECTIVES To evaluate the inter-laboratory reproducibility of blood test for liver fibrosis: FibroMeter, Fibrotest, APRI and their composites variables. DESIGN AND METHODS Four studies, including 147 patients, were performed: study #1 included 2 metachronous blood samples and 2 laboratories; studies #2, #3 and #4 included synchronous samples with assays delayed at day 1 in 12 laboratories, at day 0 in 10 laboratories and at day 0 or 1 in 2 laboratories, respectively. Agreement was evaluated by the intraclass correlation coefficient (r(ic)). RESULTS In studies #1, #2 and #4, r(ic) for FibroMeter was 0.893, 0.942 and 0.991, respectively. In study #3, the r(ic) were: FibroMeter: 0.963, Fibrotest: 0.984, APRI: 0.949. Large simulated variations in composite variables had a weak impact on FibroMeter. CONCLUSIONS When blood marker limits are controlled, inter-laboratory agreement of blood tests is excellent in clinical practice conditions. Blood tests are robust against the variability of composite blood variables.

Abstract
Haematology analysers provide quick and accurate results in most situations. However, spurious results, related either to platelets (part I of this report) or to other parameters from the cell blood count (CBC) may be observed in several instances. Spuriously low white blood cell (WBC) counts may be observed because of agglutination in the presence of ethylenediamine tetra-acetic acid (EDTA). Cryoglobulins, lipids, insufficiently lysed red blood cells (RBC), erythroblasts and platelet aggregates are common situations increasing WBC counts. In most of these instances flagging and/or an abnormal WBC differential scattergram will alert the operator. Several situations lead to abnormal haemoglobin measurement or to abnormal RBC count, including lipids, agglutinins, cryoglobulins and elevated WBC counts. Mean (red) cell volume (MCV) may be also subject to spurious determination, because of agglutinins, excess of glucose or salts and technological considerations. In turn, abnormality related to one measured parameter will lead to abnormal calculated RBC indices: mean cell haemoglobin content (MCHC) is certainly the most important RBC indices to consider, as it is as important as flags generated by the haematology analysers (HA) in alerting the user to a spurious result. In many circumstances, several of the measured parameters from CBC may be altered, and the discovery of a spurious change on one parameter frequently means that the validity of other parameters should be considered. Sensitive flags now allow the identification of several spurious counts, but only the most sophisticated HA have optimal flagging and more simple HA, especially those without a WBC differential scattergram, do not possess the same sensitivity for detecting anomalous results. Reticulocytes are integrated now into the CBC in many HA, and several situations may lead to abnormal counts.

Abstract
INTRODUCTION AL-amyloidosis is a rare disease due to monoclonal immunoglobulin deposits, secondary to lymphoproliferative disorder or primitive. The deposits of amyloidosis have usually a systemic repartition. We report a tumor like presentation of amyloidosis, so-called amyloidoma. EXEGESIS A 72-year old woman lost 10 kg within 6 months, associated with epigastric and mediastinal bulks. The biopsy of the abdominal mass showed AL-amyloidosis with kappa light chains. Since no secondary etiology could be found, the final diagnosis of primary AL-amyloidosis in a tumour like presentation, or amyloidoma, was performed. Investigations showed cardiac involvement with MRI findings, as well as kidney and bone marrow involvement. Oral melphalan as monotherapy was administered. The prognosis and the treatment of this unusual disease are discussed. CONCLUSION Amyloidoma is a rare presentation of amyloidosis which should be evocated in front of a soft tissue mass with no clear etiology.

Abstract
The widespread use of haematology analysers (HA) has led to a major improvement of cellular haematology, because of quick and accurate results found in most instances. However, in several situations, spurious results are observed. Inadequate blood samples, situations induced by the anticoagulant(s) used, peculiar changes related to the pathology in the patient, and technical considerations about performances of the various HA must be considered. Spurious thrombocytopenia occurs in several circumstances related to the presence of ethylenediamine tetra-acetic acid (EDTA) used as the anticoagulant. Mechanism of EDTA-dependent platelet (PLT) agglutination is related to circulating (auto)antibodies directed against normally hidden epitope(s) in the glycoprotein alpha IIb/beta IIIa complex from PLT membrane exposed only in the presence of EDTA. Other spuriously low PLT counts may be related to EDTA, including PLT rosetting around white blood cells (WBC; satellitism) and PLT-WBC aggregates, but mechanisms responsible for those latter phenomena are less well known. Spurious increase of PLT count may be related to several situations, including fragmented red blood cells, cytoplasmic fragments of nucleated cells, cryoglobulins, bacteria or fungi, and lipids. Flags generated in several of these situations alert the operator on possible abnormal findings and may identify the problem. Analysing only PLT parameters is not sufficient: in many situations the WBC differential scattergram is of crucial help for flagging. Flags generated depend on the software version on the HA used, the performance in detecting the same anomalies may differ according to which analyser is used, even those from the same manufacturer. Operators must be aware of the characteristics of their analyser and be able to recognize and circumvent anomalous results.

Abstract
Bacterial infections are responsible for several changes in the cell blood count, which are usually non specific, although some morphological changes of polymorphonuclear neutrophils may be indicative of sepsis. The presence of bacteria on peripheral blood smears is a rare but extreme situation, related in most instances to a fatal prognosis. The presence of both free and intracellular bacteria was observed in the peripheral blood smear of a critically ill patient with a pneumococcal septicaemia which led to a fatal outcome within the next following hours. If the finding of bacteria on the blood smear is a sign of severe sepsis, the literature review shows that less than 10% of septic patients demonstrate bacteria on the blood smear, and routine search for the diagnosis of sepsis is not recommended. Samples taken from infected central venous catheters are another situation of bacteraemia which must be known, but prognosis is usually not fatal if prompt medical care is performed. Some preanalytical conditions are also associated with the presence of bacteria on the peripheral blood smear, but unrelated to infection of the relevant patient.

Abstract
The WHO classification describes a group of myelodysplastic/myeloproliferative diseases, including a provisional entity, refractory anaemia with ringed sideroblasts (RARS) associated with marked thrombocytosis, underlining that is a provisional entity without consensus of belonging to myelodysplastic rather than to myeloproliferative syndromes. The authors report two cases with features of refractory anaemia with excess of ringed sideroblasts and marked thrombocytosis. In the first case, RARS is concomitant with thrombocytosis and fits the WHO criteria for this temporary entity. The second case is a typical RARS, who developed a thrombocytosis after several years and emphasizes that a link, at least progressive, exists between RARS and myeloproliferative disorders. The authors summed up the various situations related to secondary or primary acquired sideroblastic anaemia, likewise to primitive and reactive thrombocytosis. The cases of RARS + marked thrombocytosis reported in the literature are few in number and do not allow to settle between a particular form of myelodysplastic syndrome and a myeloproliferative disorder, a fully justified reason to classify these patients in a temporary group. To date, there is no codified therapy for this disorders.

Abstract
Morphological changes of plasma cells (PC) are common in multiple myeloma (MM). Loss of round or oval nuclear shape has been related to cell malignancy in human, and we looked for the occurrence of such morphological change on PC from bone marrow (BM) smears in a retrospective series of 169 MM patients at diagnosis. Nuclear shape changes of PC differed according to the patients (notch, dumb-bell, folded or monocytoid appearance), even in the same patient; all subtypes were pooled and defined as PC with irregular nuclear shape (PCIN). A significant number of PCIN (>/=5% of all BMPC) was found at diagnosis in 20.7%. Median survival was of 22 months for patients with >/=5% PCIN, and 41 months for others (p=0.0001). Significant relationship was observed with prognostic parameters related intrinsic malignancy of the tumour process but not with beta-2-microglobulin (b2m). A clear-cut relationship was found also between PCIN and hypodiploidy (p=0.0001), but not with deletion of chromosome 13. This study emphasises the relationship between PCIN, an easy-to-ascertain marker of intrinsic malignancy of the tumour process, and adverse prognosis.

Abstract
Idiopathic hypereosinophilic syndrome is characterised by chronic hypereosinophilia leading to tissue damage, and after exclusion of reactive eosinophilia. Until recently no specific or efficient therapeutic was available. In 2003, a recurrent interstitial deletion 4q12 leading to the fusion of the FIP1L1 and PDGFRA genes was detected in hypereosinophilic syndromes. The resulting protein has constitutive tyrosine kinase activity which explains clinical and cytological remission of hypereosinophilic syndrome after treatment by a specific tyrosine kinase inhibitor, imatinib mesylate or Glivec, usually used in chronic myeloid leukaemia. Here we report a patient with hypereosinophilic syndrome associated to peculiar morphology of neutrophilic series and the 4q12 deletion. He presented clinical and haematological remission since the introduction of imatinib mesylate therapy.

Abstract
To decrease red blood cell (RBC) transfusion requirements during high-dose therapy (HDT) for hematological malignancies, we conducted a pilot study to assess the effect of recombinant human erythropoietin (rHuEpo) given during chemotherapy before HDT and autologous peripheral stem-cell transplantation (APSCT). The transfusion histories of 15 HDT and APSCT for hematological disease performed in 11 consecutive patients who received rHuEpo (10 000 U subcutaneously three times/week) were compared to those of 22 HDT and ASCT performed in 17 consecutive historical controls matched for hematological parameters. rHuEpo increased the hemoglobin (Hb) level from 10.3+/-2.3 g/dl at diagnosis to 12.9+/-2.2 g/dl at the time of HDT in 11 patients; no major adverse effects occurred. Compared to historical controls (95%, 21/22), RBC transfusion requirements were significantly lower for rHuEpo recipients (26%, 4/15) (P=0.00001) and rHuEpo responders (15%, 2/13) (P=0.000002). After HDT and APSCT, fewer RBC transfusions were needed: 3.3, 1.2 and 0.3 RBC units for controls, rHuEpo recipients and rHuEpo responders, respectively (P=0.006 and 0.00002). Therefore, rHuEpo should be administered before, and not after HDT and APSCT, to lower RBC transfusion requirements after HDT and APSCT.

Abstract
Cytogenetic studies in lymphomas classically require fresh or frozen tissue, whereas in many instances only paraffin-embedded biopsies are available. We applied an interphase FISH assay on nuclei extracted from thick paraffin sections to determine accuracy of molecular cytogenetics in such samples. Twenty-three lymphoma samples and 4 reactive lymph nodes were tested with various commercially available DNA probes, and hybridization patterns were compared with those obtained on frozen nuclei counterparts. Successful hybridization with all probes tested was observed for 23/27 (85%) paraffin-embedded tissues and for all (100%) frozen samples, and cut-off levels defining positivity were superimposable for both situations. Chromosome changes were detected in the same way, without any false-positive or false-negative cases. Hybridization signals observed on dewaxed samples were either those classically expected to define the relevant chromosome change or were atypical: all atypical changes could be demonstrated also into nuclei from the frozen counterpart. Moreover, all typical and atypical chromosome changes observed on frozen nuclei were also detected in paraffin-embedded tissues. Our study shows that our interphase FISH assay performed on paraffin-embedded samples is a valuable alternate to conventional methods to ascertain diagnosis of lymphomas as to include patients into therapeutic trials.

Abstract
The translocation (14;18)(q32;q21) is the hallmark of follicular lymphoma (FL). However, conventional cytogenetics and PCR techniques fail to detect it in at least 10% of cases. In order to evaluate the true incidence of this translocation in FL, we analyzed 63 patients with FL, and 17 patients with diffuse large cell lymphoma (DLCL) corresponding to suspected FL transformations using interphase fluorescence in situ hybridization (FISH). Colocalized signals related to the translocation were observed in 19-92% of cells (median = 51%), corresponding to positivity over the threshold in all (63/63) cases. Similarly, 16/17 possibly secondary DLCL displayed the translocation. Although some cytogenetic changes might be missed by this FISH assay (such as rare insertion, or translocations with other chromosomal partners), our results stress t(14;18)(q32;q21) as an almost constant finding in FL. Our sensitive interphase FISH assay should be of great value to define FL more accurately, namely in patients included into therapeutic trials. Furthermore, this approach could be of interest in (re)defining some types of FL, especially the grade 3 FL which frequently lack t(14;18).

Abstract
The AML1/CBFA2/RUNX1 gene is the target of many recurrent translocations seen in different leukemia subtypes. The t(12;21)(p13;q22) is the most frequent translocation observed in childhood B acute lymphoblastic leukemia (ALL), occurring in 20% to 25% of cases. In adult ALL this rearrangement is scarce. Another route of AML1deregulation could be point mutations in the runt domain. We now report on AML1amplification in two cases of childhood ALL, found in a series of 107 consecutive children with B-lineage ALL analyzed by fluorescence in situ hybridization (FISH). A parallel analysis of 42 adult B-ALL failed to detect any AML1 rearrangement by FISH. The two patients with AML1 amplification were further analyzed using molecular techniques. SSCP analysis did not detect any mutation. Furthermore, direct sequencing of the cDNA did not reveal any mutation. In conclusion, AML1amplification seems to be observed only in childhood ALL and is not associated with AML1 gene mutation. Other mechanisms, such as gene dosage effects could be hypothesized.

Abstract
Asthma is an inflammatory disease of the airways clinically characterised by recurrent bronchial obstructions at least partially reversible. Recent epidemiologic data suggest that asthmatics have an increased rate of decrease of their expiratory volumes during life. This irreversible lung function impairment is associated with fundamental structural changes of the bronchial wall in terms of conjunctive tissue and smooth muscle composition. We describe these changes and explore the different mechanisms proposed to explain these structural modifications. We also review their consequences in terms of bronchial physiology and their potential influence on bronchial hyperresponsiveness.

Abstract
Inflammatory bowel diseases (IBD) are characterized by a sustained inflammatory cascade that gives rise to the release of mediators capable of degrading and modifying bowel wall structure. Our aims were (i) to measure the production of matrix metalloproteinase-3 (MMP-3), and its tissue inhibitor, tissue inhibitor of metalloproteinase-1 (TIMP-1), by inflamed and uninflamed colonic mucosa in IBD, and (ii) to correlate their production with that of proinflammatory cytokines and the anti-inflammatory cytokine, IL-10. Thirty-eight patients with IBD, including 25 with Crohn's disease and 13 with ulcerative colitis, were included. Ten controls were also studied. Biopsies were taken from inflamed and uninflamed regions and inflammation was graded both macroscopically and histologically. Organ cultures were performed for 18 h. Tumour necrosis factor-alpha (TNF-alpha), IL-6, IL-1beta, IL-10, MMP-3 and TIMP-1 concentrations were measured using specific immunoassays. The production of both MMP-3 and the TIMP-1 were either undetectable or below the sensitivity of our immunoassay in the vast majority of uninflamed samples either from controls or from those with Crohn's disease or ulcerative colitis. In inflamed mucosa, the production of these mediators increased significantly both in Crohn's disease (P < 0.01 and 0.001, respectively) and ulcerative colitis (P < 0.001 and 0.001, respectively). Mediator production in both cases was significantly correlated with the production of proinflammatory cytokines and IL-10, as well as with the degree of macroscopic and microscopic inflammation. Inflamed mucosa of both Crohn's disease and ulcerative colitis show increased production of both MMP-3 and its tissue inhibitor, which correlates very well with production of IL-1beta, IL-6, TNF-alpha and IL-10.
