    ABSTRACT: Human platelets undergo structural and biochemical alternations during storage which are collectively called platelet storage lesion (PSL). PSL is characterized as metabolic and functionally changes. It causes decrease in platelet recovery and survival. Here, we evaluated the effect of L-carnitine (LC) on the metabolism, function, and mitochondrial metabolic activity of platelet during storage. Platelet-rich plasma was used to prepare platelet concentrate (PC) in Iranian Blood Transfusion Organization. For this purpose, ten PC bags from healthy donors were stored at 22 °C with gentle agitation in the presence or absence of LC. The effects of LC (15 mM) on the platelet quality were assessed by analyzing the levels of glucose, lactate, ATP, and lactate dehydrogenase (LDH) activity. Platelet aggregations induced by arachidonate and ristocetin were analyzed by aggregometer. Platelet mitochondrial melablolic activity was measured by tetrazolium salt 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide (MTT) assay; platelet count and mean platelet volume were also determined by a hematology analyzer during 5 days of PC storage. The results indicated that LC could significantly decrease lactate concentration and glucose consumption accompanied with the increased oxygen consumption in stored PC. LDH activity also less significantly increased in LC-treated PC on days 2 and 5 of storage. Platelet aggregation in response to the ristocetin and arachidonate was significantly higher in LC-treated PC than that in untreated PC on day 5 of storage. Finally, platelet mitochondrial metabolic activity less significantly decreased in LC-treated PC compared to the control group on days 2 and 5 of storage. It seems that LC would be a good additive to reduce PSL and improve the platelet metabolism and quality of the stored PC for platelet transfusion therapy.

    ABSTRACT: The human leukocyte antigen DR surface expression on CD14+ monocytes reflects the degree to which these cells have been activated. Given the central role monocytes and macrophages play in the immune system, a decreased human leukocyte antigen DR expression on CD14+ monocytes results in a hallmark of altered immune status during systemic inflammatory response syndrome. We hypothesize that human leukocyte antigen DR expression might be similarly altered after hematopoietic stem cell transplantation and during post-transplant complications. Using flow cytometry, this study investigates the human leukocyte antigen DR surface expression of CD14+ monocytes in 30 pediatric and young adult patients up to 1 year after hematopoietic stem cell transplantation. Normal values were derived from a control group of healthy children, adolescents, and young adults. Human leukocyte antigen DR expression decreased significantly prior and during bacterial infection or sepsis. By contrast, human leukocyte antigen DR expression levels were elevated before and at the time of viremia. Human leukocyte antigen DR expression was also elevated during acute graft-versus-host disease. In contrast, the expression was reduced when patients had hepatic veno-occlusive disease. A significant decrease of human leukocyte antigen DR expression was associated with a relapse of the underlying disease and before death. Human leukocyte antigen DR expression on CD14+ monocytes appears to be a promising parameter that might allow identification of patients at risk after hematopoietic stem cell transplantation.

    ABSTRACT: High-risk myelodysplastic syndrome (MDS) patients have usually a less favorable outcome after intensive treatment compared with de novo acute myeloid leukemia (AML) patients. This may reflect different disease-related and patient-related factors. The purpose of this analysis is to identify disease-specific prognostic factors and to develop prognostic scores for both patient groups. A total of 692 patients in the EORTC/GIMEMA AML-10 study and 289 patients in the CRIANT study received identical remission-induction and consolidation treatment. Estimated 5-year survival rate was 34 % in the AML-10 versus 27 % in the CRIANT study, and estimated disease-free survival was 40 % versus 28 %, respectively. In multivariate analysis, cytogenetic characteristics, white blood count, and age appeared prognostic for survival in both studies. French-American-British (FAB) subtype and performance status were prognostic in the AML-10 study only, whereas number of cytopenias and duration of antecedent hematologic disorder >6 months were prognostic in the CRIANT study only. The prognostic scores distinguish three groups with a 5-year survival rate of 54, 38, and 19 % in the AML-10 study versus 69, 37, and 5 % in the CRIANT study. The prognostic value of these scores has been validated on two external series. The new scoring systems form a practical tool to predict the outcome of individual MDS and AML patients treated with intensive antileukemic therapy.

    ABSTRACT: Delayed platelet engraftment (DPE) is a common complication following allogeneic hematopoietic stem cell transplantation (allo-HSCT). This phenomenon is also a predictor of increased treatment-related mortality and poor survival. Therefore, therapies that promote platelet engraftment to prevent DPE are needed. This prospective randomized controlled trial was designed to investigate whether recombinant human thrombopoietin (rhTPO), administered subcutaneously at a daily dose of 15,000 U from the first day after transplantation, promotes platelet engraftment after haploidentical HSCT. The cumulative incidence of platelet engraftment (platelet recovery to ≥20 × 10(9)/L without transfusion support for seven consecutive days) on day 60 post-transplantation was significantly higher in the rhTPO group (n = 60) than in the control group (n = 60) (91.7 ± 3.8 % vs. 74.5 ± 5.8 %, P = 0.041). Additionally, the number of platelet transfusions from day 14 to day 60 was significantly lower in the rhTPO group than in the control group (4 ± 5 vs. 7 ± 9 Units, P = 0.018). No severe adverse effects were observed, with a median follow-up duration of 256 days (range, 48-586 days). The incidences of acute graft-versus-host disease (GVHD), chronic GVHD, and cytomegalovirus viremia and the probabilities of overall survival and disease-free survival did not differ between the two groups. A multivariate analysis of all patients revealed that regardless of assignment to the rhTPO group or the control group (hazard ratio (HR) = 1.514; 95 % CI (1.024-2.238); P = 0.038), the number of total infused CD34(+) cells (HR = 1.304; 95 % CI (1.148-1.482); P < 0.001) and slower neutrophil engraftment (HR = 2.777; 95 % CI (1.841-4.189); P < 0.001) were associated with platelet engraftment. In conclusion, rhTPO promotes platelet engraftment and safely reduces the requirement for platelet transfusion in patients after unmanipulated haploidentical HSCT. This trial was registered with the Chinese Clinical Trial Registry ( ) as ChiCTR-TRC-11001774. .

    ABSTRACT: Hydroxycarbamide (hydroxyurea or HU) has been shown to increase fetal hemoglobin (HbF) in patients with β-thalassemia intermedia (TI). The reported effects of HU in increasing the total hemoglobin (Hb) have been inconsistent. Studies of long-term therapy with HU in pediatric TI are rather uncommon. A retrospective observational study was carried out to evaluate the clinical responses to HU in Egyptian patients with β-TI. One hundred patients; children (n = 82, mean age 9.9 ± 4.1 years) and adults (n = 18) were studied for the mean Hb, HbF%, median serum ferritin, transfusion history, and splenic size before and after HU therapy (mean dose 20.0 ± 4.2 mg/kg/day, range 10-29 mg/kg/day) over a follow-up period 4 to 96 months (mean 35.4 ± 19.2 months). Molecular studies were also done for group of patients (n = 42). The overall response rate to HU was 79 %; 46 % were minor responders (with a reduction in transfusion rate by 50 % or more and/or an increase in their total hemoglobin level by 1-2 g/dl) and 33 % major responders (becoming transfusion-free and/or having an increase in total hemoglobin level by >2 g/dl). Mean hemoglobin increased among responders from 6.9 ± 0.9 g/dl to 8.3 ± 1.4 g/dl (p < 0.001). A significant rise in mean HbF (27.0 vs. 42.5 %; p < 0.011) and a decrease in median serum ferritin (800 vs. 644 ng/ml; p < 0.001) were also observed among responders (n = 45). Transfusions stopped in 44 % of pretreatment frequently transfused responders (n = 11/25). Splenic size decreased in 37 % of patients (n = 30/81). The predominant β-thalassemia mutation was 1-6 (T > C) in 32/42 (76 %) of studied patients; 28/32 were responders. Bivariate analysis showed no predictors of response as regards sex, pediatric and adult age, splenic status, or genotype. Hydroxycarbamide is a good therapeutic modality in the management of pediatric as in adult TI patients. It can minimize the need for blood transfusion, concomitant iron overload, and blood-born viral transmission especially in developing countries like Egypt.

    ABSTRACT: As survival of patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) increases and the number of patients who live long rises, health-related quality of life (HRQoL) becomes a relevant endpoint. Few studies investigated this, mainly as a secondary endpoint in randomized clinical trials where patients with early stage CLL/SLL, and elderly/frail patients were underrepresented. The aim of our study was to assess HRQoL in a population-based setting, including these previously underrepresented patients. Out of 175 patients diagnosed with CLL/SLL between 2004 and 2011, 136 (78 %) returned the HRQoL questionnaire. The outcomes were compared to an age- and sex-matched norm population. Detailed data on stage and treatment were extracted from a population-based hematological registry (PHAROS). Patients ever treated for CLL/SLL reported significantly poorer HRQoL than the norm population (p < 0.01 with large clinically important differences. Interestingly, no differences were observed between the norm population and patients under active surveillance. In contrast to our hypothesis, patients treated with chlorambucil reported the lowest HRQoL scores. Drastic, long-lasting negative effects of starting treatment on HRQoL cannot be excluded, whereas active surveillance does not seem to provoke worrying, anxiety, or depressive symptoms. Further elaborate research into the impact of starting therapy on HRQoL is needed, especially in patients that are underrepresented in most clinical trials, and thoroughly consider its results during revision of treatment guidelines.

    ABSTRACT: Cytokine-induced killer (CIK) cells, one of the feasible and effective methods of adoptive immunotherapy, have shown anti-leukemia activity in vivo and in vitro. But the strategy exhibits limited cytotoxic activity in clinical studies. In this study, CIK cells were transfected with an interleukin-3/Pseudomonas exotoxin gene (IL3PE38KDEL). RT-PCR and ELISA were used to verify the expression of IL3PE38KDEL in the transfected CIK cells. These cells released 1,186.7 ± 149.6 pg IL3PE38KDEL/10(4) cells over 48 h into the medium and the culture supernatant selectively killed IL3 receptor(IL3R)-positive HL60 cells, but not IL3R-negative K562 cells. Moreover, IL3PE38KDEL transfection did not influence phenotypes and cytokine production of CIK cells. Co-cultured with leukemia cells, IL3PE38KDEL transfected CIK cells showed enhanced cytotoxicity against IL3R-positive HL60 cells at all effector-to-target (E:T) ratios, but exerted a basal anti-leukemia activity against IL3R-negative K562 cells. Our findings demonstrate that IL3PE38KDEL gene transfection may be a novel strategy for improving anti-leukemia activity of CIK cells.

    ABSTRACT: Hereditary hemochromatosis is an autosomal recessive disorder characterized by severe iron overload. It is usually associated with homozygosity for the HFE gene mutation c.845G > A; p.C282Y. However, in some cases, another HFE mutation (c.187C > G; p.H63D) seems to be associated with the disease. Its penetrance is very low, suggesting the possibility of other iron genetic modulators being involved. In this work, we have screened for HAMP promoter polymorphisms in 409 individuals presenting normal or increased serum ferritin levels together with normal or H63D-mutated HFE genotypes. Our results show that the hepcidin gene promoter TG haplotype, originated by linkage of the nc.-1010C > T and nc.-582A > G polymorphisms, is more frequent in the HFE_H63D individuals presenting serum ferritin levels higher than 300 μg/L than in those presenting the HFE_H63D mutation but with normal serum ferritin levels or in the normal control group. Moreover, it was observed that the TG haplotype was associated to increased serum ferritin levels in the overall pool of HFE_H63D individuals. Thus, our data suggest that screening for these polymorphisms could be of interest in order to explain the phenotype. However, this genetic condition seems to have no clinical significance.

    ABSTRACT: Numbers of observational studies suggest that the JAK2 46/1 (GGCC) haplotype may increase the risk of myeloproliferative neoplasms (MPNs) and splanchnic vein thrombosis (SVT), but the results remain controversial. We aimed to examine the association between the JAK2 46/1 haplotype and risk of MPNs and SVT by conducting a meta-analysis. PubMed, EMBASE, Cochrane Library, CBM, and CNKI databases were searched to identify eligible studies without restrictions and by reviewing reference lists of obtained articles. Both fixed and random-effects models were used to calculate the summary risk estimates. We identified 26 observational studies of the JAK2 46/1 haplotype and risk of MPNs and SVT involving 8,561 cases and 7,434 participants. In the overall analysis, it was found that the JAK2 46/1 haplotype significantly elevated the risk of MPNs (rs10974944: C vs T: odds ratio (OR) = 2.19, 95 % confidence interval (CI) = 1.86-2.57, P < 0.0001; CC vs TT: OR = 4.63, 95 % CI = 3.32-6.47, P < 0.0001; CT vs TT: OR = 2.49, 95 % CI = 2.11-2.95, P < 0.0001; (CC + CT) vs TT: OR = 2.92, 95 % CI = 2.51-3.39, P < 0.0001; rs12343867: C vs T: OR = 1.88, 95 % CI = 1.59-2.22, P < 0.0001; CC vs TT: OR = 3.16, 95 %CI = 2.14-4.65, P < 0.0001; CT vs TT: OR = 2.04, 95 % CI = 1.51-2.74, P < 0.0001; (CC + CT) vs TT: OR = 2.25, 95 % CI = 1.73-2.95, P < 0.0001) and SVT (C vs T: OR = 1.27, 95 % CI = 1.06-1.52, P = 0.011; CC vs TT: OR = 2.33, 95 % CI = 1.42-3.81, P = 0.001; (CC + CT) vs TT: OR = 1.25, 95 % CI = 1.02-1.53, P = 0.034). There was no evidence of a significant association between the rs12343867 and the risk of SVT in the genetic model (CT vs TT: OR = 1.01, 95 % CI = 0.80-1.29, P = 0.906). This meta-analysis provides new evidence supporting the conclusion that the JAK2 46/1 haplotype enrichment is significantly associated with the development of MPNs and SVT in these patients.

    ABSTRACT: Dear Editor,Iron deficiency and iron deficiency anemia (IDA) are the most common nutritional deficiencies worldwide, and severe IDA in childhood results in serious complications [1, 2]. The incidence of IDA caused by congenital duodenal malformation, however, is very low [1, 3]. We report herein a rare case of congenital duodenal stenosis (CDS) misdiagnosed as simple IDA for 20 years.On 23 April 2012, a 20-year-old man was referred to our department with the complaints of 20 years of progressive vomiting, anorexia, pallor, upper abdominal pain, and 3-kg weight loss in the previous 6 months. He occasionally vomited milk after birth. At 5 years of age, he was diagnosed with IDA based on pallor, hemoglobin concentration of 57 g/L, mean corpuscular volume of 61 fL, mean corpuscular hemoglobin (MCH) of 23.5 pg, and MCH concentration of 241 g/L. Oral iron therapy improved his pallor, but this symptom recurred after treatment discontinuation. At 10 years of age, he had lower body weight, heig

    ABSTRACT: Induction therapy with fludarabine followed by rituximab and consolidation plus maintenance with rituximab improved response duration (RD) and overall survival (OS) in our patients with chronic lymphocytic leukemia (CLL). The aim of our study was to investigate the clinical impact of NOTCH1 mutations in this setting of patients. The study included 123 progressive CLL patients homogeneously assigned to first-line induction treatment with fludarabine followed by rituximab. Fifty-nine patients either in complete remission (CR) minimal residual disease positive (MRD+) after induction (n = 39) or in partial remission (PR, n = 20) underwent consolidation/maintenance therapy with rituximab. Sixteen patients in CR MRD + or PR underwent observation only. The presence of NOTCH1 mutations was investigated by amplification refractory mutation system (ARMS) PCR and by Sanger sequencing. NOTCH1 mutations occurred in 20 out of 123 (16.3 %) cases. Consolidated patients showed longer OS than unconsolidated patients (p = 0.030). Both NOTCH1 mutated and CR MRD+ or PR NOTCH1 mutated patients showed significantly shorter OS after treatment (p = 0.00014 and p = 0.0021, respectively). Moreover, NOTCH1 wild-type consolidated cases experienced significantly longer RD and OS than NOTCH1 mutated consolidated or not consolidated cases (p = 0.00001 and p = 0.018, respectively). Finally, the independent prognostic impact of NOTCH1 mutations for OS was confirmed in multivariate analysis (p < 0.001). The presence of NOTCH1 mutations identifies a CLL subset with worse prognosis in the setting of a rituximab-based induction and consolidation treatment.

    ABSTRACT: AIDS-related aggressive B cell lymphoma (HIV-NHL) is the second most common HIV-associated malignancy. In contrast, Hodgkin-lymphoma (HL) is one of the most common non-AIDS-defining malignancies. Current evidence-based recommendations for the treatment of HIV-associated lymphoma (HIV-lymphoma) are not available. A panel of experts in the field of HIV-related lymphoma performed literature searches of the PubMed, Medline, and Cochrane databases. The consensus process was carried out as an e-mail and meeting-based discussion group. Six cycles of R-CHOP or R-EPOCH are standard of care for patients (pts) with diffuse large B cell lymphoma (DLBCL). Pts with Burkitt lymphoma and good performance status should receive dose-intensive regimens such as the GMALL B-ALL/NHL protocol. Standard therapy has not been defined for pts with plasmablastic and primary effusion lymphoma. Pts with lymphoma in sensitive relapse should receive high-dose chemotherapy followed by autologous stem cell transplantation. Stage- and risk adapted treatment yields high remission and survival rates in pts with HIV-HL similar to those achieved in HIV-negative HL pts. Combination antiretroviral therapy (cART) should be applied concurrently to chemotherapy provided that pharmacokinetic interactions are being considered. Pts with HIV-lymphoma should usually be treated in an identical manner to HIV-negative patients.
