Abstract
The discovery of hemolytic anemia requires a meticulous investigation to determine its etiology. Among patients of African origin, it is not uncommon to find multiple constitutional red blood cell abnormalities, which can complicate diagnosis. We herein describe the case of a two-year-old child presenting with acute hemolytic anemia. A G6PD deficiency, hereditary spherocytosis, and a sickle cell trait A/S were simultaneously identified, all within the context of a primary infection with Parvovirus B19. This virus commonly triggers acute anemia in children exhibiting constitutional red blood cell abnormalities and need to be considered in such cases.

Abstract
Introduction Sickle cell disease (SCD) is an inherited hemoglobinopathy disorder. The main consequence is synthesis of hemoglobin S leading to chronic hemolysis associated with morbidity. The aim of this study was to investigate Thrombin Generation Assay (TGA) to assess hypercoagulability in SCD and TGA parameters as biomarkers of vaso-occlusive crisis (VOC) risk and hospitalization within 1 year. Materials and methods We performed TGA in platelet poor plasma (PPP) with 1 pM of tissue factor and 4 μM of phospholipid-standardized concentration, in duplicate for patients and controls. We measured thrombomodulin (TM), soluble endothelial Protein C Receptor and Tissue Factor Pathway Inhibitor (TFPI). Results A total of 113 adult patients with SCD, 83 at steady state and 30 during VOC, and 25 healthy controls matched on age and gender were included. Among the 83 patients at steady state, (36 S/S-1 S/β0, 20 S/Sα3.7, and 19 S/C-7 S/β+) 28 developed a VOC within 1 year (median: 4 months [2.25–6]). We observed an increase of peak and velocity associated with a shortening of lagtime and time to peak (TTP) and no difference of endogenous thrombin potential (ETP) in patients compared to controls. TFPI (p < 0.001) and TM (p = 0.006) were significantly decreased. TGA confirmed hypercoagulability in all SCD genotypes and clinical status. The association of ETP > 1,207 nM.min and peak >228.5 nM presented a sensitivity of 73.5% and a specificity of 93.9% to predict VOC development within 1 year. Conclusion We have demonstrated a hypercoagulable state in SCD associated with chronic hemolysis. These preliminary findings suggest that TGA parameters, as ETP and peak, could be used to predict VOC development within 1 year.

Abstract
Sickle cell disease is a complex genetic disease involving cell adhesion between red blood cells, white blood cells, platelets and endothelial cells, inducing painful vaso-occlusive crisis (VOC). We assessed reticulocyte and erythrocyte parameters in a cohort of confirmed SCD patients, and investigated whether a combination of these routine laboratory biomarkers of haemolysis could be used to predict VOC development. Reticulocyte and erythrocyte parameters were evaluated using the Sysmex XN-9000 analyser. A total of 98 patients with SCD were included, 72 in steady state and 26 in VOC. Among the 72 patients in steady state, 22 developed a VOC in the following year (median: 3 months [2-6]). The following parameters were increased in SCD patients with VOC development compared to SCD patients without VOC development in the following year: reticulocyte count (94.6 109/L [67.8-128] vs. 48.4 109/L [24.9-87.5]), immature reticulocyte count (259 109/L [181-334] vs. 152 109/L [129-208]) reticulocyte/immature reticulocyte fraction (IRF) ratio (6.63 109/(L*%) [4.67-9.56] vs. 4.94 109/(L*%) [3.96-6.61]), and medium fluorescence reticulocytes (MFR) (19.9% [17.4-20.7] vs. 17.1% [15.95-19.75]). The association of a reticulocyte count of >189.4 109/L and an MFR of >19.75% showed a sensitivity of 81.8% and a specificity of 88% to predict VOC development in the following year. Based on our findings, a combination of routine laboratory biomarkers, as reticulocyte count, immature reticulocyte count and fluorescent reticulocyte fraction at steady state, could be used to predict VOC development in SCD.

Abstract
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/GATA1 ratio and decreased α/β-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 STAT5 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
We describe the clinical, hematologic and genetic characteristics of a retrospective series of 126 subjects from 64 families with hereditary xerocytosis. Twelve patients from six families carried a KCNN4 mutation, five had the recurrent p.Arg352His mutation and one had a new deletion at the exon 7-intron 7 junction. Forty-nine families carried a PIEZO1 mutation, which was a known recurrent mutation in only one-third of the cases and private sequence variation in others; 12 new probably pathogenic missense mutations were identified. The two dominant features leading to diagnosis were hemolysis that persisted after splenectomy and hyperferritinemia, with an inconstant correlation with liver iron content assessed by magnetic resonance imaging. PIEZO1-hereditary xerocytosis was characterized by compensated hemolysis in most cases, perinatal edema of heterogeneous severity in more than 20% of families and a major risk of post-splenectomy thrombotic events, including a high frequency of portal thrombosis. In KCNN4-related disease, the main symptoms were more severe anemia, hemolysis and iron overload, with no clear sign of red cell dehydration; therefore, this disorder would be better described as a ‘Gardos channelopathy’. These data on the largest series to date indicate that PIEZO1-hereditary xerocytosis and Gardos channelopathy are not the same disease although they share hemolysis, a high rate of iron overload and inefficient splenectomy. They demonstrate the high variability in clinical expression as well as genetic bases of PIEZO1-hereditary xerocytosis. These results will help to improve the diagnosis of hereditary xerocytosis and to provide recommendations on the clinical management in terms of splenectomy, iron overload and pregnancy follow-up.

Abstract
The risk and clinical significance of cardiac iron overload due to chronic transfusion varies with the underlying disease. Cardiac iron overload shortens the life expectancy of patients with thalassemia, whereas its effect is unclear in those with myelodysplastic syndromes (MDS). In patients with sickle cell anemia (SCA), iron does not seem to deposit quickly in the heart. Our primary objective was to assess through a multicentric study the prevalence of cardiac iron overload, defined as a cardiovascular magnetic resonance T2*<20 ms, in patients with thalassemia, SCA, or MDS. Patient inclusion criteria were an accurate record of erythrocyte concentrates (ECs) received, a transfusion history >8 ECs in the past year, and age older than 6 years. We included from 9 centers 20 patients with thalassemia, 41 with SCA, and 25 with MDS in 2012-2014. Erythrocytapharesis did not consistently prevent iron overload in patients with SCA. Cardiac iron overload was found in 3 (15%) patients with thalassemia, none with SCA, and 4 (16%) with MDS. The liver iron content (LIC) ranged from 10.4 to 15.2 mg/g dry weight, with no significant differences across groups (P = 0.29). Abnormal T2* was not significantly associated with any of the measures of transfusion or chelation. Ferritin levels showed a strong association with LIC. Non-transferrin-bound iron was high in the thalassemia and MDS groups but low in the SCA group (P<0.001). Hepcidin was low in thalassemia, normal in SCA, and markedly elevated in MDS (P<0.001). Two mechanisms may explain that iron deposition largely spares the heart in SCA: the high level of erythropoiesis recycles the iron and the chronic inflammation retains iron within the macrophages. Thalassemia, in contrast, is characterized by inefficient erythropoiesis, unable to handle free iron. Iron accumulation varies widely in MDS syndromes due to the competing influences of abnormal erythropoiesis, excess iron supply, and inflammation.

Abstract
INTRODUCTION The use of a red blood cell transfusion in a patient with major sickle cell disease is sometimes necessary. The occurrence of delayed haemolytic transfusion reaction is a rare but potentially serious complication. This event can occur at any age. It is probably under diagnosed due to the difficulty in diagnosis with few specific signs. CASE REPORTS We describe in this article the clinical, biological, and hazards of therapeutic management of three cases of delayed haemolytic transfusion reaction in sickle cell disease patients. The high performance chromatography, which evaluates the percentage of HbA1, is the biological investigation used to establish the diagnosis of this event. The pathophysiology of this event remains still poorly understood. Several treatments have been used during this event. However, the therapeutic management remains controversial. CONCLUSION Transfusion in any patient likely to suffer from delayed haemolytic transfusion reaction is not recommended because of the risk of worsening this reaction. Prevention of recurrence is essential.

Abstract
OBJECTIVES To analyze the main characteristics of adults with sickle cell disease (SCD) and concurrent connective tissue disease (CTD). METHODS A retrospective investigational study was performed. CTD was diagnosed according to standard international criteria. Severity of SCD was assessed by a clinical severity score. RESULTS Thirty patients, 23 women (76%) and 7 men, with hemoglobin S/S (n = 25) or S/C (n = 5) SCD were included. The subtypes of CTD were rheumatoid arthritis (RA) (n = 15), definite systemic lupus erythematosus or "incomplete lupus" requiring treatment (n = 13), primary Sjögren's syndrome with central nervous system involvement (n = 1), and systemic sclerosis (n = 1). Twenty-five of the 30 patients (83%) received steroid treatment, and 15 (50%) received at least 1 immunosuppressive agent (methotrexate in 14 cases) to control CTD. Four RA patients were given antitumor necrosis factor (TNF)alpha and 1 was treated with rituximab without SCD exacerbation. After a median follow-up of 4.5 years [range: 6 months to 30 years] from CTD diagnosis, 11 of the 25 (44%) patients receiving steroids had at least 1 episode of severe infection (mostly due to Staphylococcus aureus or Escherichia coli). SCD exacerbated in 13 of the 30 (43%) patients after CTD onset; 12 of these patients were receiving prednisone and/or methotrexate. Six patients (20%) had died from sepsis (n = 2), stroke (n = 2), or acute chest syndrome (n = 2). CONCLUSIONS CTD-related clinical manifestations and outcome were not particularly severe in patients with SCD. However, those with active CTD and undergoing steroid +/- methotrexate treatment had more serious SCD-related manifestations, a higher rate of severe infections, and an overall patient mortality rate of 20%. Thus, the management of patients with CTD and underlying SCD should consider the risk/benefit ratio of each treatment and steroid-sparing strategies should be implemented.

Abstract
Although dehydroepiandrosterone (DHEA) is widely used in the elderly to prevent some adverse effects of ageing, possible deleterious side effects have not been fully assessed. We evaluated the direct actions of DHEA and DHEA sulphate on angiogenesis, a critical event in pathologies that are common in the elderly (cancer, atherosclerosis, inflammation... etc.). At physiological concentrations found in human plasma following DHEA therapy (1-50 nM), DHEA had no action on angiogenesis in vitro. In contrast, higher concentrations of DHEA (10-100 microM), which can be found in tissues after local administration or storage, inhibited in vitro endothelial cell proliferation (blockage in G2/M), migration and capillary tube formation and in vivo angiogenesis in the Matrigel plug assay. This inhibition might be due to a decreased glucose-6-phosphate dehydrogenase activity and to a modification of the tubulin network involved in cell proliferation and migration. The sulphate ester form of DHEA had no effect on angiogenesis.

Abstract
Hemoglobinopathies have become a significant national health problem in France. The biologists have a pivotal role in the genetic diagnoses. Although sickle cell disease (SCD) is the most frequent abnormality found: not less than 200 new cases are observed each year at birth, many other globin gene variations are found in the various ethnic groups. Since 1995 a neonatal sickle cell screening program has been established for at risk newborns. This programme is supported by the "Association française de dépistage et prévention des handicaps de l'enfant" (AFDPHE). The characterization of hemoglobin genetic variations requires a comprehensive set of laboratory techniques for which we specify here main clinical and technical recommendations.

Abstract
To assess the influence of initial diameter on the gender difference in flow-dependent dilatation (FDD) of the conduit artery, we measured radial artery internal diameter (echotracking), flow (Doppler) and total blood viscosity in 24 healthy (25 +/- 0.8 yr) men and women during reactive hyperemia (RH) and during a gradual hand skin heating (SH). At baseline, mean diameter (men, 2.76 +/- 0.09 vs. women, 2.32 +/- 0.07 mm, P < 0.05), flow (men, 21 +/- 4 vs. women, 10 +/- 1 ml/min, P < 0.05), and blood viscosity (men, 4.13 +/- 0.07 vs. women, 3.92 +/- 0.13 cP, P < 0.05) were higher in men but mean shear stress (MSS) was not different between groups. During RH, the percent increase in diameter was lower in men (men, 9 +/- 1 vs. women, 13 +/- 1%, P < 0.05). This difference was suppressed after correction for baseline diameter. During SH, the increase in diameter with flow was higher in women (P < 0.01). However, the increase in MSS was higher in women because of their smaller diameter at each level of flow (P < 0.01) and there was no difference between groups for the increase in diameter at each level of MSS. These results demonstrate in a direct manner that initial diameter influences the magnitude of FDD of conduit arteries in humans by modifying the value of the arterial wall shear stress at each level of flow and support the interest of the heating method in presence of heterogeneous groups.

Abstract
Hb Mont Saint-Aignan [beta128(H6)Ala-->Pro] is a mildly unstable variant, associated with hemolytic anemia, marked microcytosis and increased alpha/beta biosynthetic ratio (1.55 versus 1.1 +/- 0.1 in the control). The abnormal chain was isolated by selective precipitation with isopropanol and the structural modification determined by protein chemistry methods (reversed phase high performance liquid chromatography and mass spectrometry). Possible mechanisms underlying the beta(+)-thalassemia-like expression of this variant are discussed.

UNLABELLED Drug administration during the last trimester of pregnancy may have adverse effects for the newborn. CASE REPORT A hemolytic anemia occurred during the first hours of life in a full-term neonate whose mother had taken nitrofurantoin during the last month of pregnancy. CONCLUSION The immature enzymatic systems of the neonate are exposed to this adverse effect and justify the recommendation not to prescribe nitrofurantoin at the end of pregnancy.

Abstract
Erythropoietin (EPO) is the main red cell growth factor and its release into the blood stream is stimulated by anemia and also by various kinds of hypoxia. We studied the blood EPO concentration in a population of 96 infants who died suddenly and compared their mean EPO levels to control infants. The normal values were low at birth and progressively increased during the first 2 years. In the sudden infant death (SID) group the EPO level was significantly higher (p = 0.001) for the entire population and particularly in the youngest group (0-2 months): 14.7 +/- 2.4 IU/l (mean +/- SEM) in SID group vs. 3.6 +/- 0.4 IU/l in control group (p < 0.001). Although we could not analyze the blood hemoglobin concentration after death, the anemia hypothesis was refuted by an assay of the percentage of fetal hemoglobin which was normal for age in the control and SID groups. Moreover, there was no significant difference in EPO levels between explained and unexplained deaths. We also observed an increase in the stress hormones, cortisol and beta-endorphin, in the entire SID group. These SID results suggest a profound and long-lasting hypoxia at least during terminal agony.

Abstract
Recent studies noted the contribution of alpha42Tyr to the T-R-dependent UV resonance Raman (UVRR) spectral changes of HbA [Nagai, M., et al. (1996) J. Mol. Struct. 379, 65-75; Huang, S., et al. (1997) Biochemistry 36, 6197-6206], but the observed UVRR changes of the Tyr residue cannot be fully interpreted with alpha42Tyr alone. To identify the remaining contributions, the 235 nm-excited UVRR spectra of Tyr mutant Hbs at alpha140, beta35, and beta145 were investigated here. The Fe-His stretching mode demonstrated that all of these mutant Hbs take the T structure in the deoxy form under these experimental conditions. The UVRR change of the Trp residue of these mutants upon the T-R transition was the same as that in HbA, indicating that the T-R-dependent UVRR change of beta37Trp is not due to stacking with Tyr residues but is due to the formation or destruction of a hydrogen bond. The recombinant Hbs beta35Tyr --> Phe and beta35Tyr --> Thr both exhibited UVRR spectra identical with that of HbA, meaning that beta35Tyr is not responsible. In the spectra of des(beta146His,beta145Tyr)Hb with inositol hexaphosphate, the frequency shift of the Tyr RR bands was the same as that in HbA but the intensity enhancement in the CO form was small, suggesting that beta145Tyr contributes to a part of the intensity change, but scarcely relates to the frequency shift. In the spectra of Hb Rouen (alpha140Tyr --> His), the frequency shifts of bands at 1617 (Y8a) and 1177 (Y9a) cm-1 following ligation were half of those in HbA, while the intensity enhancement was not detected. This result means that alpha140Tyr is responsible for both the frequency shift and the intensity changes. It is suggested that the frequency shift of the Tyr RR bands upon the T --> R transition is due to changes in the hydrogen bonding state of alpha42- and alpha140Tyr and that the intensity enhancement is due to changes in the environment of the penultimate Tyr in both alpha and beta subunits (alpha140 and beta145). These alterations in the vibrational spectra clearly demonstrate which tyrosine residues are involved in the T-R transition as a result of modification of their local environments.

Abstract
Hb Les Andelys [alpha83(F4)Leu-->Pro] is a mildly unstable variant that was found during glycated hemoglobin measurement in a French family. In this hemoglobin molecule the affected site, in the alpha chain, and the amino acid substitution are identical to those of Hb Santa Ana, an unstable beta chain variant. The structural abnormality was demonstrated by protein chemistry methods, involving, in addition to the classical techniques, a selective precipitation of the abnormal hemoglobin by isopropanol and a mass spectrometry analysis of the alphaT-9 peptide following carboxypeptidase digestion. DNA sequencing demonstrated that the mutation was CTG-->CCG at codon 83 of the alpha2 gene.

Abstract
Hb Rouen (alpha 140(HC2) Tyr-->His) is a moderately high oxygen-affinity variant that was found in coincidence with polycythemia vera in a French patient. This hemoglobin provides an example of an alteration of the C-terminus of the alpha-chain, a region involved in the mechanisms of allosteric regulation. The increase in oxygen-affinity and decrease in cooperativity of this variant is much smaller than that resulting from the same substitution in the beta-chain. This model provides additional evidence for the inequivalence between the alpha- and beta-subunits.

Abstract
Spectrin Rouen (beta 220/218) is a novel variant, carrying a shortened beta chain with an apparent molecular weight of 218 kDa. It was detected in a French family. All affected members suffered from haemolytic hereditary elliptocytosis. As other shortened beta chain variants described before, the beta Rouen chain is truncated at its carboxyl terminus. Spectrin Rouen is associated with a defect in spectrin dimer self-association and with an abnormally high amount of the alpha I 74 kDa peptide following partial tryptic digestion. Dimer reconstitution experiments from normal and abnormal purified Sp subunits indicated that the increased alpha I 74 kDa fragment is induced by the altered beta chain. However, spectrin Rouen is different from other mutants with a truncated beta chain in several respects: its amount is low (less than 10%) and the spectrin dimer self-associated defect is mild. Critically, the beta Rouen chain has retained the ability of undergoing phosphorylation, even though it is modified in its C-terminal region. These results, compared to those obtained with beta 220/214 spectrin Le Puy and beta 220/216 spectrin Nice, allowed better localization of the beta chain sites that can be phosphorylated by a membrane-bound casein kinase.
