Assessment of Stem Cell Transplant Eligibility in Recipients with Oral Foci of Infection: Appropriate Conditioning Regimens.

Objectives: It is unclear whether patients with oral foci of infection should be approved for hematopoietic stem cell transplant with or without posttransplant cyclophosphamide. We compared the presence of oral foci of infection status on the effects of various conditioning regimens for such patients.

Materials And Methods: Three groups were classified as autologous (carmustine-etoposide-cytarabinemelphalan, mitoxantrone-melphalan, and melphalan 200 mg/m² groups; n = 502 patients), and 6 groups were classified as allogeneic (busulfan-fludarabinerabbit anti-T-lymphocyte globulin, busulfanfludarabine-posttransplant cyclophosphamide, fludarabine-cyclophosphamide-anti-T-lymphocyte globulin, busulfan-fludarabine-anti-T-lymphocyte globulin-posttransplant cyclophosphamide, total body irradiation-posttransplant cyclophosphamide, and other; n = 428 patients).

Comparison of the clinical course of COVID-19 infection in sickle cell disease patients with healthcare professionals.

It is highly expected that COVID-19 infection will have devastating consequences in sickle cell disease (SCD) patients due to endothelial activation and decreased tissue and organ reserve as a result of microvascular ischemia and continuous inflammation. In this study, we aimed to compare the clinical course of COVID-19 in adult SCD patients under the organ injury mitigation and clinical care improvement program (BASCARE) with healthcare professionals without significant comorbid conditions. The study was planned as a retrospective, multicenter and cross-sectional study.

Comparison of Outcomes of Transplant and Nontransplant High-Risk Chronic Lymphocytic Leukemia Patients in the Novel Targeted Therapy Era.

Objectives: Our aim was to compare patients with high-risk chronic lymphocytic leukemia referred to our transplant center who underwent allogeneic stem cell transplant with those who did not receive this treatment. Factors compared included demographics, clinical characteristics, and survival rates in the novel targeted therapy era.

Materials And Methods: All 33 patients with high-risk chronic lymphocytic leukemia who were referred to the hematopoietic stem cell transplant center were enrolled in this retrospective, single-center nonrandomized study.

The Impact of the Ferric Carboxymaltose on Hemoglobin and Ferritin Levels.

Background: Anemia is a frequent disorder worldwide. Iron deficiency anemia (IDA) is the most common form of anemia. Although oral iron is the first choice for treatment, the efficacy of oral iron preparations may be limited.

Factors Associated With Overall Survival in Acute Myeloid Leukemia Patients Before and After Hematopoietic Stem Cell Transplant.

Objectives: Our aim was to identify factors associated with overall survival and the efficacy of postrelapse treatment protocols and to determine whether pretransplant consolidation therapy and minimal residual disease status pose a survival benefit.

Materials And Methods: Patients with acute myeloid leukemia who underwent stem cell transplant between 2007 and 2018 were enrolled retrospectively. The effects of pretransplant cytogenetic and minimal residual disease status, pretransplant consolidation therapies, development of graft-versus-host disease, postrelapse treatment protocols, and type of con-ditioning regimens on overall survival were analyzed.

Frequency of Finding Family Donors: A Single Center Experience.

Objectives: Allogeneic hematopoietic stem cell transplant is a curative treatment option for many hematologic diseases. The existence of a fully compatible donor for recipients is the first condition for minimized transplant-related mortality and morbidity. The best donor for hematopoietic stem cell transplant is an HLA-matched sibling donor.

Organ damage mitigation with the Baskent Sickle Cell Medical Care Development Program (BASCARE).

The Eastern Mediterranean is among the regions where sickle cell disease (SCD) is common. The morbidity and mortality of this disease can be postponed to adulthood through therapies implemented in childhood. The present study focuses on the organ damage-reducing effects of the Baskent Sickle Cell Medical Care Development Program (BASCARE), which was developed by a team who lives in this region and has approximately 25 years of experience.

Anti-HLA Antibody Levels Are Associated With the Risk of Graft Failure After Allogeneic Hematopoietic Stem Cell Transplant.

Objectives: Allogeneic hematopoietic stem cell transplant provides a curative treatment for a considerable amount of hematologic diseases, and it is widely used today. Successful allogeneic stem cell transplant can be compromised by treatment-related toxicity, graft-versus-host disease, infectious complications, disease relapse, and graft failure. Primary graft failure is an important cause of hematopoietic stem cell transplant failure.

East Mediterranean region sickle cell disease mortality trial: retrospective multicenter cohort analysis of 735 patients.

Sickle cell disease (SCD), one of the most common genetic disorders worldwide, is characterized by hemolytic anemia and tissue damage from the rigid red blood cells. Although hydroxyurea and transfusion therapy are administered to treat the accompanying tissue injury, whether either one prolongs the lifespan of patients with SCD is unknown. SCD-related mortality data are available, but there are few studies on mortality-related factors based on evaluations of surviving patients.

Anorectal Complications During Neutropenic Period in Patients with Hematologic Diseases.

Background: Neutropenic patients are susceptible to any anorectal disease, and symptomatic anorectal disease afflicts 2-32% of oncology patients. Perianal infections are the most feared complication, considering the lack of natural defense against infectious microorganisms. When septic complications develop, the anorectal disease is potentially fatal, especially in neutropenic patients in whom mortality rates range between 11-57%.

Clinical Relevance of Apheretic Graft Composition in Patients With Acute Myeloblastic Leukemia Who Received a Busulfan-Fludarabine-Antithymocyte Globulin Conditioning Regimen for Allogeneic Transplant.

Objectives: Sparse data are available about the effects of apheretic graft composition on the clinical transplant outcome in allotransplanted patients who have hematologic malignant disease. Major obstacles in recent studies have included heterogeneity of patient populations and differences in the conditioning regimens used.

Materials And Methods: This prospective study included 50 patients who had acute myeloblastic leukemia and received busulfan-fludarabine-antithymocyte globulin-based conditioning for peripheral allogeneic stem cell transplant.

Prophylactic red blood cell exchange may be beneficial in the management of sickle cell disease in pregnancy.

Background: Sickle cell disease (SCD) is associated with chronic hemolysis and painful episodes. Pregnancy accelerates sickle cell complications, including prepartum and postpartum vasoocclusive crisis, pulmonary complications, and preeclampsia or eclampsia. Fetal complications include preterm birth and its associated risks, intrauterine growth restriction, and a high rate of perinatal mortality.

Clinical significance of circulating blood and endothelial cell microparticles in sickle-cell disease.

Increased thrombocyte activation leads to a higher likelihood of coagulation in sickle-cell disease. On the other hand, chronic inflammation and endothelial cell activation promote vaso-occlusion. The effect of circulating microparticles derived from erythrocytes, monocytes, thrombocytes, and endothelial cells on the vaso-occlusive process is unclear.

Short-term central venous catheter complications in patients with sickle cell disease who undergo apheresis.

Patients with sickle cell disease (SCD) are prone to develop thrombosis and infection due to their inflammatory and immune deficiency state. These patients require red cell exchange therapy for treatment or prevention of hemoglobin S associated complications. Owing to vascular access problems, adult patients need central venous catheterization (CVC) for exchange procedures.

Cranial involvement in sickle cell disease.

Purpose: To evaluate cranial findings in patients with neurologically symptomatic sickle cell disease (SCD).

Materials And Methods: We studied 50 consecutive patients with SCD and neurologic symptoms. All patients underwent brain MR examinations: all 50 underwent classic MR imaging; 42, diffusion-weighted MR imaging; 10, MR angiography; four, MR venography; and three patients, digital subtraction angiography.
