Hematopoietic Stem Cell Transplantation in Sickle Cell Disease: A Multidimentional Review.

While exagamglogene autotemcel (Casgevy) and lovotibeglogene autotemcel (Lyfgenia) have been approved by the US Food and Drug Administration (FDA) as the first cell-based gene therapies for the treatment of patients 12 years of age and older with sickle cell disease (SCD), this treatment is not universally accessible. Allogeneic hematopoietic stem cell transplant (HSCT) has the potential to eradicate the symptoms of patients with SCD, but a significant obstacle in HSCT for SCD is the availability of suitable donors, particularly human leukocyte antigen (HLA)-matched related donors. Furthermore, individuals with SCD face an elevated risk of complications during stem cell transplantation due to SCD-related tissue damage, endothelial activation, and inflammation.

Graft failure after allogeneic hematopoietic stem cell transplantation in pediatric patients with acute leukemia: autologous reconstitution or second transplant?

Background: Graft failure (GF) is a rare but serious complication after allogeneic hematopoietic stem cell transplantation (HSCT). Prevention of graft failure remains the most advisable approach as there is no clear recommendation for the best strategies for reversing this complication. Administration of growth factor, additional hematopoietic progenitor boost, or a salvage HSCT are current modalities recommended for the treatment of GF.

Determining the predictive impact of donor parity on the outcomes of human leukocyte antigen matched hematopoietic stem cell transplants: a retrospective, single-center study.

Introduction: Donor choosing remains to play a pivotal role in allogeneic hematopoietic stem cell transplantation (allo-HSCT). Numerous criteria beyond HLA compatibility impact the selection of a suitable donor.

Methods: We evaluated the effect of donor parity on transplant outcomes in a large homogeneously treated population that received an HLA-matched allo-HSCT between 2010 and 2021 at our center.

Clinical Features and Risk Factors of Relapse and Mortality in Thrombotic Thrombocytopenic Purpura Patients: A Seven-Year Experience.

: Thrombotic thrombocytopenic purpura (TTP) is associated with microangiopathic hemolytic anemia, thrombocytopenia, and microvascular thrombosis. No comprehensive report exists on clinical characteristics and risk factors of relapse and mortality in Iranian TTP patients. In this study, we aimed to report clinical features of Iranian TTP patients, to evaluate disease relapse and mortality rate and their associated risk factors.

Comparable Outcomes of Pre- Versus Post-Tyrosine Kinase Inhibitor Era Treatment in Chronic Myeloid Leukemia: A Retrospective Cohort Study With Long-term Follow-up.

Imatinib, a selective BCR-ABL tyrosine kinase inhibitor (TKI), was introduced after allogeneic hematopoietic stem cell transplantation (allo-HSCT) for patients with chronic myeloid leukemia (CML). However, the long-term effects of allo-HSCT in chronic phase CML patients are mostly unknown. We retrospectively analyzed the outcomes of 204 patients with sibling donors who received peripheral stem cells and underwent allo-HSCT of chronic phase I (CP1) in the pre- and post-TKI era at Shariati Hospital in Tehran, Iran, from 1998 to 2017 and followed up till the end of 2021.

The Economic Burden of Acute Myeloid Leukemia in Iran.

Background: Cancer imposes a significant economic burden on the health system and society. Acute myeloid leukemia (AML) is the third deadliest leukemia and is one of the leading health problems worldwide. The present study aimed to estimate the economic burden of AML in Iran for 2020.

Radiation-free reduced-intensity hematopoietic stem cell transplantation with in vivo T-cell depletion from matched related and unrelated donors for Fanconi anemia: prognostic factor analysis.

Fanconi anemia (FA) is a rare and complex genetic disorder, clinically characterized by bone marrow failure, congenital defects, and cancer predisposition. Hematopoietic stem cell transplantation (HSCT) represents the only therapeutic option to restore normal hematopoiesis after the occurrence of marrow failure or clonal hematopoietic abnormality. However, radiation exposure during transplant may increase the risk of later malignancies.

COVID-19 and cancer: A comparative case series.

Background: Cancer patients, with an incidence of more than 18 million new cases per year, may constitute a significant portion of the COVID-19 infected population. In the pandemic situation, these patients are considered highly vulnerable to infectious complications due to their immunocompromised state.

Material & Methods: In this retrospective case series, the documents of solid cancer patients infected by SARS-CoV-2, hospitalized in Shariati hospital between 20 February and 20 April 2020, were evaluated.

Clinical characteristics, outcomes, and risk factors for mortality in hospitalized patients with COVID-19 and cancer history: a propensity score-matched study.

Background: COVID-19 has caused great concern for patients with underlying medical conditions. We aimed to determine the prognosis of patients with current or previous cancer with either a PCR-confirmed COVID-19 infection or a probable diagnosis according to chest CT scan.

Methods: We conducted a case control study in a referral hospital on confirmed COVID-19 adult patients with and without a history of cancer from February to April, 2020.

Hematologic predictors of mortality in hospitalized patients with COVID-19: a comparative study.

: The first cases of proved COVID-19 in Iran were reported in February 2020 and has since rapidly spread worldwide. We aimed to clarify the clinical significance of hematologic parameters alteration in COVID-19. : Different hematologic parameters were measured in 225 hospitalized COVID-19 patients in a tertiary care university hospital, during the peak of COVID-19 outbreak and their association with duration of hospitalization, ICU admission and especially mortality was analyzed.

Outcome of Peripheral Blood Allogeneic Hematopoietic Stem Cell Transplantation as a Treatment Option in Patients With Severe Aplastic Anemia Between 40 and 50 Years.

The frontline treatment for patients younger than 40 years with severe aplastic anemia (AA) is allogeneic hematopoietic stem cell transplantation (HSCT) from a human leukocyte antigen-identical sibling donor. However, in patients with severe AA who are older than 40 years, allogeneic HSCT has been found to be associated with increased treatment-related mortality and toxicity, even when matched sibling donors are used. We report our institutional experience with allogeneic HSCT in patients with severe AA between 40 and 50 years.

Indicators of male fertility potential in adult patients with beta-thalassemia major: a comparative study between patients undergone allogeneic stem cell transplantation and transfusion-dependent patients.

Background: Allogeneic hematopoietic stem cell transplantation (HSCT) remains the only potentially curative treatment for thalassemia major (TM). Infertility and its indicators have been assessed in transfusion dependent TM men, but in this study, we sought to compare the fertility indicators of TM patients after HSCT with those in patients treated conventionally. The possible influential factors on reproductive capacity in TM patients undergone allogeneic HSCT were also evaluated.

Microvesicles of osteoblasts modulate bone marrow mesenchymal stem cell-induced apoptosis to curcumin in myeloid leukemia cells.

Microvesicles (MVs) derived from bone marrow niche components have an important role in genetic reprogramming and subsequent drugs induce apoptosis in leukemic cells. Here, we have found that undertreatment of curcumin or daunorubicin, the cross-talk through MVs of KG-1-bone marrow mesenchymal stem cells (BMSCs), significantly downregulates the expression of the survival gene osteopontin (OPN), CXCL-12, IL-6 (interleukin-6), STAT-3, and VCAM-1 (vascular cell adhesion molecule 1) in treated-KG-1 cells as well as exclusively upregulates CXCL-12 in BMSCs. Drug treated-cell populations' MVs of both single cultured osteoblasts (OBs) and cocultured KG-1 + BMSCs + OBs similarly upregulate survival mediators' OPN, CXCL-12, IL-6, STAT-3, and VCAM-1 in treated-KG-1 cells.

Evaluation of procalcitonin and neopterin level in serum of patients with acute bacterial infection.

Background: Fever as a common presenting complaint in pediatric patients can be due to various causes. Differentiating bacterial infection from other causes is important because the prompt use of antibiotics is critical in bacterial infection. Traditional markers of infection such as BT and WBC count may be unspecific and culture may be late or absent.
