Multiple myeloma (MM) is a malignancy of plasma cells, terminally differentiated B cells, with complications like hypercalcemia, renal failure, anemia, and bone disease, which are also known as CRAB criteria. MM develops from monoclonal gammopathy of unknown significance (MGUS), a pre-malignant plasma cell dyscrasia. Over some time, MGUS has the potential to progress into smoldering multiple myeloma (SMM), which can evolve into MM. MM rarely progresses into plasma cell leukemia (PCL), a condition in which malignant plasma cells no longer stay in the bone marrow niche and circulate in the peripheral blood. In MM, various soluble factors play important roles, and interleukin-6 has different vital roles. Interleukin-6, an inflammatory cytokine, has significant roles in the growth, survival, angiogenesis, metastasis, and apoptosis resistance in MM. Interleukin-6 is produced and secreted by both autocrine from myeloma cells and paracrine from bone marrow stromal cells. To tackle MM, various therapeutic approaches were applied over many years, and according to the results, most patients with MM can respond well to first-line treatment. However, the majority of patients may relapse as conventional treatment may not be curative. So, there is an urgent need for novel cell-based and cell-free therapeutic strategies, such as mesenchymal stem cell-based therapies and their products to offer new therapeutic strategies for MM. Materials and Methods: In the present study, we investigated the impacts of exosomes derived from human placental mesenchymal stem cells (hPMSCs) on apoptosis and interleukin-6 expression in a myeloma cell line, U-266, for the first time. hPMSCs were isolated from the human placenta and cultured in a DMEM medium. After characterizing the cells and acknowledging their identity, they underwent several passages and their supernatant was collected to harvest exosomes. The exosomes were isolated by ultracentrifugation and characterized by DLS and TEM, and their concentration was measured by BCA protein assay. U266 cells were treated with different concentrations of exosomes and then MTT and annexin/propidium iodide flow cytometry tests were performed to evaluate cell viability. Afterward, a real-time PCR test was performed to evaluate interleukin-6 gene expression. Results: According to our findings, treatment of U-266 cells with hPMSCS-derived exosomes led to the preservation of myeloma cells without changes in their cell cycle. Surprisingly, treatments did not hinder the expression of interleukin-6 in the myeloma cells. Conclusion: In MM patients, interleukin-6 plays different roles, and it is a desirable target to design new therapeutic strategies. To evaluate the effects of new therapeutic strategies, we designed and performed our study to estimate the effects of cell-free therapeutic strategy. In the present study, the impacts of hPMSCS-derived exosomes on the viability of MM cells and interleukin-6 gene expression were evaluated.
多发性骨髓瘤（MM）是一种浆细胞（终末分化的 B 细胞）恶性肿瘤，具有高钙血症、肾功能衰竭、贫血和骨病等并发症，这也被称为 CRAB 标准。MM 是由意义不明的单克隆丙种球蛋白病（MGUS）发展而来的，MGUS 是一种恶性前浆细胞异常。经过一段时间后，MGUS 有可能发展为烟雾型多发性骨髓瘤（SMM），SMM 又可能发展为 MM。MM很少发展为浆细胞白血病（PCL），在这种情况下，恶性浆细胞不再停留在骨髓龛中，而是在外周血中循环。在 MM 中，各种可溶性因子发挥着重要作用，其中白细胞介素-6 发挥着不同的重要作用。 白细胞介素-6 是一种炎性细胞因子，在 MM 的生长、存活、血管生成、转移和抗凋亡中起着重要作用。白细胞介素-6通过骨髓瘤细胞的自分泌和骨髓基质细胞的旁分泌产生和分泌。针对骨髓瘤，多年来人们采用了多种治疗方法，结果表明，大多数骨髓瘤患者对一线治疗反应良好。不過，由於傳統治療未必能根治，大部分病人可能會復發。因此，迫切需要新型的细胞和无细胞治疗策略，如间充质干细胞疗法及其产品，为 MM 提供新的治疗策略。材料与方法：在本研究中，我们首次研究了从人胎盘间充质干细胞（hPMSCs）中提取的外泌体对骨髓瘤细胞系U-266的细胞凋亡和白细胞介素-6表达的影响。在确定细胞特征并确认其身份后，对其进行了多次传代，并收集其上清液以收获外泌体。通过超速离心法分离外泌体，用 DLS 和 TEM 对其进行表征，并用 BCA 蛋白检测法测定其浓度。用不同浓度的外泌体处理 U266 细胞，然后用 MTT 和附件素/碘化丙啶流式细胞术检测细胞活力。之后，进行实时 PCR 检测以评估白细胞介素-6 基因的表达。结果根据我们的研究结果，用源自 hPMSCS 的外泌体处理 U-266 细胞可保存骨髓瘤细胞，且细胞周期不会发生变化。令人惊讶的是，治疗并未阻碍骨髓瘤细胞中白细胞介素-6的表达。结论是在 MM 患者体内，白细胞介素-6 发挥着不同的作用，是设计新治疗策略的理想靶点。为了评估新治疗策略的效果，我们设计并开展了无细胞治疗策略的效果评估研究。 本研究评估了源自 hPMSCS 的外泌体对 MM 细胞活力和白细胞介素-6 基因表达的影响。结果表明，hPMSCS衍生的外泌体可使骨髓瘤细胞存活下来，而细胞周期不会发生变化。 此外，白细胞介素-6基因表达水平也没有发生显著变化。

Background: Von Willebrand disease (VWD) is one of the most common coagulative diseases, so identifying the effective factors in preventing this complication is essential. The study aimed to evaluate the frequency of demographic and epidemiological findings in VWD patients referred to a hospital in Zahedan, Iran. Materials and Methods: This study was performed on 76 patients with VWD referred to Hazrat Ali-Asghar Hospital in Zahedan City, Sistan, and Baluchestan province. After obtaining consent from the patients, the demographic information and clinical symptoms of the disease were recorded. All statistical analyses were performed using SPSS 22.0 software. All descriptive data were expressed as mean ±SD and percent (%) depending on the continuous and dichotomous variables. A P-value ≤0.05 was considered significant statistically. Results: The present study results showed that the highest age group of VWD patients at the time of disease diagnosis was in the age group 1-5 years (47.3%), and most patients had type III VWD (80.3%). It was also found that 67.1% of patients had a positive family history and their parents' consanguineous marriage (77.6%). The most common complaints were epistaxis (88.15%), cutaneous bleeding (78.94%), and oral cavity bleeding (61.84%), respectively. Conclusion: Due to the high prevalence of VWD in consanguineous marriages and an increase in adverse complications and symptoms in VWD patients, proper diagnosis and screening at an early age, especially in people with family history, is essential. Efforts are needed to develop national registries and widely provide the required and available basic services for diagnosis and treatment.

Background: Busulfan plus cyclophosphamide (Bu/Cy) is considered one of the classical myeloablative conditioning regimens. However, its toxicity can significantly increase mortality rates. To reduce both acute and long-term complications after hematopoietic stem cell transplantation (HSCT), newer conditioning regimens are being investigated. The purposes of this study were to assess the efficacy and safety of busulfan plus cyclophosphamide (Bu/Cy) and busulfan plus fludarabine (Bu/Flu) conditioning regimen for allogeneic HSCT (allo-HSCT) in acute myelogenous leukemia (AML). Materials and Methods: We conducted a single-center, retrospective analysis of AML, both adults and children, who underwent either Bu/Cy or Bu/Flu conditioning regimen for allo-HSCT and received peripheral blood stem cell transplants from HLA-matched donors. Results: From 2005 – 2019, 49 AML patients receiving Bu/Cy and 21 receiving Bu/Flu were identified, meeting inclusion criteria. The two groups showed no significant differences in age, gender, disease status pre-transplant, the median time to neutrophil and platelet engraftment. Bu/Flu patients had a shorter duration of neutropenia (median 7 days vs 10 days, p = 0.001) and shorter duration of thrombocytopenia (median 10 days vs 15 days, p = 0.016) than Bu/Cy. No difference was observed in disease-free survival (DFS) and overall survival (OS) between the two groups. Both univariate and multivariate analyses showed that age, disease status pre-transplant, and chronic graft-versus-host disease (GvHD) are related to worse DFS and OS. Conclusion: With similar efficacy to Bu/Cy but faster neutrophil and platelet recovery time, Bu/Flu is suitable as a pre-HSCT conditioning regimen for patients with AML.

Background: Thrombocytopenia is a frequent complication after hematopoietic stem cell transplantation (HSCT). Although platelet transfusion is the most used treatment for severe thrombocytopenia, it is associated with well-established risks. High-intensity interval exercise (HIIE) results in thrombocytosis. Therefore, this study aimed to reduce thrombocytopenia by increasing platelet count through exercise. Materials and Methods: Twenty lymphoma and multiple myeloma patients were divided into HIIE and control groups. To determine the maximal exercise capacity, patients in the HIIE group performed a graded exercise test. All patients received granulocyte colony-stimulating factor for 5 days, followed by a HIIE trial. After 5 min warm up at 10 to 20% of peak power, patients in the HIIE group performed an HIIE protocol that included 12 intervals of one-minute work at 100% peak power interspersed by one-minute active rest at 20% of peak power. Patients in the control group were seated for the same duration without any physical activity. Two blood samples were taken before and immediately after the trials and were analyzed for measuring complete blood count. Results: Platelet count on the day of platelet engraftment in the HIIE group was significantly higher than in the control group (P=0.02). Single-donor platelet transfusion was significantly lower in the HIIE group than in the control group (P=0.05). Conclusion: Based on the findings of the present study, a short bout of HIIE had a positive effect on platelet engraftment through thrombocytosis and reduced platelet transfusion and its complications, which could be a useful strategy for HSCT patients.

Background: Hematological abnormalities in COVID-19 infection included quantitative and qualitative changes and should be further characterized. Evaluation for myelodysplastic syndromes (MDS) is usually prompted by abnormal hematologic findings and the presence of dysplastic morphologies. Viral infections are considered to be the cause of dysplastic morphologies and should be considered by morphologists. There are few reports of dysplastic abnormal morphologies in patients with COVID-19 infection. However, such correlations still have to be clarified. Materials and Methods: In the present study, we examined the granulocyte lineage morphological abnormalities in symptomatic RT-PCR-confirmed COVID patients. Peripheral blood samples were collected from 82 patients with symptomatic COVID-19. Blood smears were prepared according to the standard Wright-Giemsa staining procedure. The morphological examination was carried out by two laboratory experts. Results: Blood smear examination revealed common myelodysplastic syndrome (MDS) type abnormalities including but not limited to pseudo-pelger nuclear lobulation (4.8%), hypogranulation (7.3%), Howell-Jolly-like bodies or detached nuclear segments (6.0%) and elongated and thin nuclear filaments (6.0%). One case of abnormal immature granulocyte and ring form nucleus is also evident. Conclusion: Our results accounted for the possibility of active COVID-19 infection in all subjects with granulocyte dysplasia. These results are of practical importance for patients suspected of having myelodysplastic syndromes or disease processes associated with myeloid malignancies.

Background: Graft Versus Host Disease (GvHD), which can be observed at a rate of 30-80% after allogeneic stem cell transplantation (ASCT) is an important complication that adversely affects the survival and quality of the life of patients. Posttransplant cyclophosphamide (PTCy) effectively prevents GvHD after HLA-haploidentical ASCT. In our study, the use of PTCy in 1-antigen HLA-mismatched unrelated donor (9/10MMUD) ASCT was compared with standard GvHD prophylaxis in HLA-identical related donor (MRD) ASCT. Materials and Methods: We conducted a retrospective study of the comparison of 42 patients with 9/10 MMUD ASCT receiving PTCy+Methotrexate (MTX)+Calcineurin Inhibitor (CNI) and 37 patients with HLA-identical MRD who received MTX+CNI in 3 bone marrow transplantation centers. Results: Cumulative incidences of grade I-II (64.6% vs 45.4%, p=0.187) or grade III to IV acute GvHD (35.4% vs54.6%, p=0.187) and chronic GvHD (11.9% vs 29.7%, p=0.096) were similar in the PTCy group and control group. No statistically significant differences were observed between PTCy and the control group in overall survival rate (52.4% vs 62.2%, p=0.381), progression-free survival (1483.97 vs 1200.70 days, p=0.502), relapsed-related mortality rate (21.4% vs 16.2%, p=0.556) and treatment-related mortality rate (16.7% vs 21.6%, p=0.575). Conclusion: With the addition of PTCy to standard GvHD prophylaxis in 9/10MMUD ASCT, the risk of GvHD due to incompatibility and unrelated transplantation is eliminated, and transplantation success is achieved with MRD ASCT. PTCy-based prophylaxis is an effective and safe strategy to prevent GvHD in 9/10 MMUD ASCT without increasing the risk of relapse and treatment-related mortality.
背景：同种异体干细胞移植（ASCT）后，移植物抗宿主疾病（GvHD）的发病率高达30%-80%，它是影响患者生存和生活质量的重要并发症。移植后环磷酰胺（PTCy）可有效预防HLA-同种异体干细胞移植后的GvHD。在我们的研究中，我们将在 1 抗原 HLA 不匹配的非亲属供者（9/10MMUD）ASCT 中使用 PTCy 与在 HLA 相同的亲属供者（MRD）ASCT 中使用标准 GvHD 预防措施进行了比较。材料与方法：我们进行了一项回顾性研究，比较了在 3 个骨髓移植中心接受 PTCy+ 甲氨蝶呤 (MTX)+ 钙嘌呤抑制剂 (CNI) 的 42 例 9/10 MMUD ASCT 患者和接受 MTX+CNI 的 37 例 HLA 相同的 MRD 患者。 研究结果PTCy组和对照组的I-II级（64.6% vs 45.4%，P=0.187）或III-IV级急性GvHD（35.4% vs 54.6%，P=0.187）和慢性GvHD（11.9% vs 29.7%，P=0.096）累积发生率相似。PTCy组与对照组在总生存率（52.4% vs 62.2%，P=0.381）、无进展生存期（1483.97 vs 1200.70天，P=0.502）、复发相关死亡率（21.4% vs 16.2%，P=0.556）和治疗相关死亡率（16.7% vs 21.6%，P=0.575）方面均无统计学差异。结论在9/10MMUD ASCT的标准GvHD预防中加入PTCy，可消除因不相容和非亲缘移植导致的GvHD风险，并通过MRD ASCT获得移植成功。在9/10MMUD ASCT中，以PTCy为基础的预防是预防GvHD的有效而安全的策略，同时不会增加复发风险和治疗相关死亡率。

Background: Hematopoietic stem cell transplantation (HSCT) is considered as the last treatment option in many life-threatening diseases. The number of donated cells can affect transplantation success. This study attempted to investigate the relationship between the health-promoting lifestyle of allogeneic stem cell donors and the number of donated CD34+ and CD3+ cells. Materials and Methods: The study was a descriptive correlational study in which 100 peripheral blood stem cells donors participated. A demographic form and health-promoting lifestyle profile-II questionnaire were distributed to participants, and then cell separation was started. Afterward, the results of CD34 + and CD3 + cell counts, as well as other clinical parameters of the participants, were recorded. The collected data were analyzed by descriptive and analytical statistical methods. Results: The results showed that the mean total health-promoting lifestyle profile score for hematopoietic stem cell donors was 2.876±0.461. There was no significant relationship between the health- promoting lifestyle score and the number of CD34+, CD3+ cells and CD3+/CD34+ ratio. A positive and significant correlation was found between the weight of the donors and the number of CD34+ (P < 0.001) and CD3+ cells (P = 0.001). The number of CD34+ cells was significantly different between women and men (P = 0.009). Conclusion: Lifestyle had no significant effect on the number of CD3+/CD34+ cells. Moreover, the number of CD34+ cells was significantly higher in men, so males should be preferentially recruited as donors for the HSCT procedure.

Background: Extranodal natural killer (NK)/T-cell lymphoma, nasal type is a rare, aggressive, and poor prognostic subtype. The concurrent chemoradiotherapy followed by chemotherapy showed a relatively high response rate and the toxicity due to the treatment is acceptable. The study attempted to report the clinicopathological features, the survival outcome, and response rates of stages I-II, nasal type ENKTL patients treated with CCRT followed by adjuvant VIPD chemotherapy in Vietnam. Materials and Methods: The current study was conducted on 31 stage I or II NK/T cell lymphoma, nasal-type patients received by CCRT, followed by adjuvant VIPD chemotherapy. Information on patient demographics, disease stage, clinical symptoms, tumor, and paraclinical characteristics were collected. The primary endpoints of this study were OS and response rates. Results: After CCRT, 26 out of 31 (83.9%) patients had stable disease or response. Overall response rate (ORR) was observed in 80.6% of patients with a complete response rate of 67.7%. Low-risk PINK patients had a higher response rate than the intermediate- risk group (p=0.038). Mean disease-free survival was 44.3±4.5 months (95% CI, 35.4-53.1 months). Mean overall survival was 46.8±4.5 months (95% CI, 37.99-55.8 months). The intermediate-risk PINK patients had a significantly lower OS rate than low-risk patients. Conclusion: Concurrent chemoradiotherapy followed by adjuvant VIPD chemotherapy showed a high response rate and survival benefit in stages I-II, nasal type, and extranodal natural killer (NK)/T-cell lymphoma Vietnamese patients.
