Conclusion: We conclude that miR-221/222 cluster correlates with more favorable R-ISS stage, revealing a potential favorable prognostic value in MM patients. MiR-15a and miR-16 correlate with the presence of osteolytic disease in MM. The observed decreased expression of these two miRNAs in symptomatic MM patients with osteolytic lesions could constitute a possible biomarker for the occurrence of bone disease. Moreover, decreased expression of miR-16 and miR-155 in MM patients, compared to sMM patients may indicate a putative predictive biomarker able to distinguish symptomatic patients from sMM patients. This ongoing study will further reveal the possible prognostic significance of this 10 miRNAs signature studied, when response to therapy, progression-free and overall survival is available.

The methods of detection of MRD has remarkably improved regarding sensitivity and specificity, and different methods such as real time quantitative polymerase chain reaction (RQ-PCR), multi-parametric flow cytometry (MFC), digital PCR or next generation sequencing (NGS) are currently used in clinical practice. Recently, Digital PCR has been adopted for quantitative assessment of MRD. However, the best method still needs to be determined. While enhancement in standardization of the different MRD approaches was reported, optimal timing and specific threshold for intervention need to be defined. Therefore well-designed clinical studies are required to diminish the risk of relapse and improve overall survival.

However, DT has not been studied in Egyptian patients. We aimed to study the prevalence of distress among Egyptian patients with different types of cancers using DT. Methods: A total of 550 patients with newly diagnosed hematological and solid cancers who were followed up at 3 Oncology Centers in Egypt were enrolled. They completed a sociodemographic and clinical status questionnaire, the DT and the Problem List (PL) scale. Results: At a DT cutoff score of ≥4, 46% of patients had significant distress, which was related to the tumor site and stage. The most frequent problems reported were treatment decision (64.4%), worry (47%), and fears (44.5%). In univariate logistic regression analysis, participants who had significant distress described 23 out of 36 problems in the practical, family, emotional, and physical areas. After adjustment to sociodemographic and clinical characteristics, multivariable analysis confirmed that insurance, depression, fear, sadness, worry, loss of interest in usual activity, and sleep were independent factors associated with significant distress in cancer patients. Conclusions: Almost half of Egyptian patients newly diagnosed with cancer reported significant distress. Those who had significant distress described extra problems in the practical, family, emotional, and physical areas. We recommend the routine use of DT for screening Egyptian patients with cancer, as well as the involvement of the psycho-oncology and social services, at the time of their initial diagnosis.

Th22 cells have been reported to play a role in infection, chronic inflammation, tumor development, autoimmune disease pathogenesis, and cell development. However, the role and number of cells whose carrying IL-22 in patients with hematopoietic stem cell transplantation is unknown. In this study, the number of circulating cells carrying IL-22, IL-17A, TNF-␣ and IFN-␥ were investigated before hematopoietic stem cell transplantation (at stem cell infusion day) and during engraftment. Methodology: A total of 10 patients who underwent autologous or allogeneic hematopoietic stem cell transplantation consecutively at the

Transthoracic echocardiography revealed a free-floating large thrombus traversing the right atrial cavity. Transesophageal echocardiography confirmed the presence of an unattached thrombus that originated from the most proximal part of the inferior vena cava. Multi-slice computed tomography of the chest and abdomen revealed the thrombus to start from the intra-hepatic part of the inferior vena cava and extend through the right atrium. It also demonstrated multiple thrombi in the pulmonary vasculature, the largest being in the right main pulmonary artery and its lower lobe branch. The patient was triaged for surgical embolectomy under cardio-pulmonary bypass. Follow-up trans-thoracic and transesophageal echocardiography confirmed adequate removal of the thrombus. By genetic examination, she proved to have factor V 'Leiden' gene and two thrombophilia genes, all of which were positive in the heterozygous state. She had also a high serum homocysteine.

Chronic myelogenous leukemia, or CML, is another name for chronic myeloid leukemia (CML), a cance... more Chronic myelogenous leukemia, or CML, is another name for chronic myeloid leukemia (CML), a cancer type that starts in certain bone marrow blood-forming cells. The primary initiator of granulocytic proliferation in CML, a myeloproliferative malignancy, is the BCR-ABL1 fusion protein or Philadelphia chromosome. CML is classified into three stages: chronic, accelerated, and blast. It has been widely recognized that the likelihood of developing CML varies by gender, geography, and age. In the chronic phase of CML (CML-CP), bleeding is a rare sign since the thrombocyte and coagulation functions are still adequate. Uncertainties exist regarding the CML bleeding mechanism. We report four cases of CML-CP in adult patients. The majority of these patients had CML and had idiopathic spontaneous bleeding in multiple locations.

However, most clinical trials excluded patients with central nervous system (CNS) involvement due to uncertain efficacy and safety. Material and methods: On January 1, 2022, we searched PubMed to identify all published literature associated with current commercial CAR T-cell therapies for B-NHL, including tisagenlecleucel (tisa-cel), axicabtagene ciloleucel (axicel), brexucabtagene autoleucel (brexu-cel), and lisocabtagene maraleucel (liso-cel). Studies that involved patients with either primary or secondary CNS lymphoma, and evaluated response rate, adverse events (AEs), or survival were included and summarized. Result: Herein, we summarize the results of 11 studies qualified for our inclusion criteria, reporting 58 lymphoma patients with CNS Involvement with 44 evaluable for clinical response, 25 for immune effector cell-associated neurotoxicity syndrome (ICANS) and 48 for Cytokine release syndrome (CRS). Objective response was achieved in 62% (16/26) of patients, and CR was achieved in 52% (23/44) of patients. Forty-four percent (11/25) developed ICANS, and 35% (17/48) developed severe ICANS (grade≥3). CRS was reported in 63% (15/24) of patients, while severe CRS (grade≥3) was reported in 7% (3/42) of patients. Conclusion: Based on our PubMed literature review, we conclude that CAR T-cell therapy may benefit patients with CNS lymphoma with promising response rates and acceptable AE. However, definite conclusions cannot be drawn until data with a larger sample size is available.

MiHA alleles were analysed using the PCR-SSP. Results: Among 200 healthy individuals, 45.7% had HA-1H allele and 54.2% the HA-1 R allele matching according to Hardy-Weinberg Equilibrium (HWE). Allelic variant genotype distribution in healthy population was as follows; RR with 26.5%, HH with 8% and HR with 55.5%. Among individuals with hematopoietic malignancies, the allelic frequency was for H 43.3%, and for R allele 56.6% which was not different in recipients/donor pairs. Allelic variant genotype distribution was for RR 35%, for HH 10% and for HR 55%. Ten patients were MiHA incompatibile and 50% of them developed aGVHD. Conclusion: MiHA distribution in Turkish population as a mixed ethnic Asian European population was found to be similar to the other populations. However, the study conducted by Kotzampasaki et al. from Greece, with 49 healthy bone marrow donors revealed the HA-1H, and HA-1R in a frequency of 29%, and 70%, respectively. Goulmy et al. found the HA-1H, and HA-1R as 47.6%, 52.4% in Asian/Pasific islanders, as 47.8%, and 52.2% in the black population, and as 35.9%, 64.1% in white population. This study included a large study cohort as 2262 individuals with 10 different MiHA genotyping from 16 countries, and in 6 different ethnic groups in 5 different continents. MiHA frequency n healthy Turkish population based on our study seemed to be not different from other countries. İn addition to MHAs, MiHA identification may determine the immune response type which may be predictive for the clinical outcome. As a target for posttransplant T-cell immunotherapy.

For blood centers, extension of WB storage time from 8 to 24 h would very useful because of significant operational and logistical benefits. This work was carried out to assess the quality of PCs prepared from WB that had been held overnight at ambient temperature compared with that of PCs prepared from fresh WB donations over a 5-day storage period. Study design and methods Thirty units of WB were collected; 15 U were kept at room temperature for 6-8 h before platelet preparation (fresh group) and 15 U were kept in a controlled environment of 20-24°C for 22-24 h before platelet preparation (overnight group). Results PCs prepared after an 8-h or a 24-h hold were comparable in platelet count per PC. CD62P expression and pH values were significantly lower in PCs prepared from 24-h hold donations. Conclusion The quality of PC may in fact improve because of the ambient overnight hold period as evidenced by lower CD62P expression throughout the storage period, which indicates a lower level of platelet activation. The lower pH values detected in overnight PCs remained within the international acceptable range. Egyptian J Haematol 39:-0 © 2014 The Egyptian Society of Haematology.

A subset analysis was performed on patients whose date of engraftment was known. Results In total, 216 individual patients were included in the ...

For blood centers, extension of WB storage time from 8 to 24 h would very useful because of significant operational and logistical benefits. This work was carried out to assess the quality of PCs prepared from WB that had been held overnight at ambient temperature compared with that of PCs prepared from fresh WB donations over a 5-day storage period. Study design and methods Thirty units of WB were collected; 15 U were kept at room temperature for 6-8 h before platelet preparation (fresh group) and 15 U were kept in a controlled environment of 20-24°C for 22-24 h before platelet preparation (overnight group). Results PCs prepared after an 8-h or a 24-h hold were comparable in platelet count per PC. CD62P expression and pH values were significantly lower in PCs prepared from 24-h hold donations. Conclusion The quality of PC may in fact improve because of the ambient overnight hold period as evidenced by lower CD62P expression throughout the storage period, which indicates a lower level of platelet activation. The lower pH values detected in overnight PCs remained within the international acceptable range. Egyptian J Haematol 39:-0 © 2014 The Egyptian Society of Haematology.
