New Treatment Methods in Multiple Myeloma

Abstract

Multiple myeloma accounts for 10% of the hematologic malignancies and is characterized by a single clone of plasma cells producing a monoclonal protein. The aim of this review is to summarize the current treatment methods of multiple myeloma. In the last 15 years, the incidence of myeloma has increased in patients younger than 65 years, thus treatment became even more important in order to obtain a long lasting remission or plateau phase. The treatment of this disease is complex and focuses not only on increasing the patients’ survival, but also improving their quality of life.

Acute Coronary Syndromes in Patients with Hematological Disorders

Abstract

Hematological conditions can lead to serious disturbances in blood rheology, being frequently associated with increased systemic inflammation and increased risk of bleeding. The imbalance between coagulation and thrombolytic factors in patients with acute coronary syndromes may lead to undesirable outcomes, and the success of emergency coronary angioplasty or by-pass grafting may be altered by increased bleeding in coagulopathies such as hemophilia. This paper intends to review the present knowledge in the field of acute coronary syndromes in subjects with hematological and onco-hematological disorders such as thrombotic thrombocytopenic purpura, immune thrombocytopenic purpura, von Willebrand disease, hemophilia, polycythemia vera, erythrocyte disorders, myelodysplastic syndrome, leukemia, lymphoma or myeloma.

Imaging-derived Biomarkers Associated with Atrial FIBROsis, Structural Remodeling and the Risk of Cardioembolic Events in Patients with Atrial Fibrillation – the FIBROS Study

Abstract

Recent studies demonstrated that despite restoration of the sinus rhythm, patients with a positive history of atrial fibrillation (AF) are still at risk of thromboembolic events. The primary objective of this study is to identify new imaging-derived biomarkers provided by modern imaging technologies, such as cardiac computed tomography angiography, delayed enhancement magnetic resonance imaging, or speckle tracking echocardiography, as well as hematological biomarkers, associated with the risk of intracavitary thrombosis in patients with AF, in order to identify the imaging-derived characteristics associated with an increased risk of cardioembolic events. Imaging data collected will be post-processed using advanced techniques of computational modeling, in order to fully characterize the degree of structural remodeling and the amount of atrial fibrosis. The primary endpoint of the study is represented by the rate of thromboembolic events. The rate of cardiovascular death, the rate of major adverse cardiovascular events, and the rate of AF recurrence will also be determined in relation to the degree of structural remodeling and atrial fibrosis.

Therapeutic Angiogenesis for Severely Ischemic Limbs — from Bench to Bedside in Acute Vascular Care

Abstract

Severe limb ischemia represents a critical condition, being associated with high morbidity and mortality rates. Patients with critical limb ischemia (CLI) require urgent initiation of interventional or surgical treatment, as restoration of the blood flow is the only way to ensure limb salvage in these critical cases. At the same time, in acute limb ischemia, a dramatic form of sudden arterial occlusion of the lower limbs, the integrity of the limb is also seriously threatened in the absence of urgent revascularization. From patients with CLI, 40% are “no option CLI”, meaning patients in whom, due to anatomical considerations or to the severity of the lesions, there is no possibility to perform interventional or surgical treatment or they have failed. Therapeutic angiogenesis has been proposed to serve as an effective and promising alternative therapy for patients with severe limb ischemia who do not have any other option for revascularization. This review aims to present the current status in therapeutic angiogenesis and the role of different approaches (gene or cell therapy, intra-arterial vs. intramuscular injections, different sources of cells) in increasing the rates of limb salvage in patients with severe ischemia of the lower limbs.

Noninvasive Assessment of Coronary Arteries in Patients with Hematologic Disorders

Abstract

Hematological conditions and their treatments have an increased risk of cardiovascular events, and invasive interventions have a higher risk of periprocedural complications in this group of patients. The aim of this review was to evaluate the risk of invasive interventions in patients with hematologic disorders and to underline the role of noninvasive cardiovascular screening in patients with hematological disorders such as Hodgkin and non-Hodgkin lymphoma, anemia, hemophilia, thrombocythemia, polycythemia vera, and leukemia. Based on present knowledge in the field, our opinion is that the screening of patients with hematological diseases is very important to reduce the morbidity and mortality due to cardiovascular events. Noninvasive assessments are suitable for this purpose with a significantly lower risk compared to invasive interventions.

The Importance of Positive Immunomagnetic Cell Separation Prior to Autologous Hematopoetic Stem Cell Transplantation for Advanced Stage Lymphomas

Abstract

We present the method of immunomagnetic stem cell separation with the ISOLEX 300i device (Isolex® 300i Magnetic Cell Selection System, Nextell Therapeutics Inc. Irvine California 21618 USA) and the results obtained using this method in patients admitted to the Hematology and Bone Marrow Transplantation Clinic of Tîrgu Mureş, Romania. Cell selection has a great importance in separating stem cells from tumor cells, therefore contributing to the success of autologous stem cell transplantation.

Unrelated Allogeneic Stem Cell Transplantation in a Patient with Chronic Myeloid Leukemia in Blast Crisis

Abstract

Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder, which can involve the hematopoietic stem cell or early progenitor cells, without the loss of their capacity to differentiate. Typically, CML has three clinical phases: a chronic phase, an accelerated phase, and an aggressive transformation in blast crisis, analogous to acute leukemia. The following article presents the case of a 49-year-old patient diagnosed with Philadelphia-negative CML in blastic transformation, where after multiple conventional acute leukemia induction chemotherapy regimens an unrelated allogeneic hematopoietic stem cell transplant was performed.

Prognosis of Patients with Acute Myeloid Leukemia Regarding the Presence FLT3 Gene Mutation – a Case Report

Abstract

Acute myeloid leukemia (AML) is a cancerous disease affecting the myeloid line of the bone marrow cells. FLT3, also known as CD135, is a proto-oncogene, which, if mutated, leads to different types of cancer. The protein it encodes presents tyrosine-kinase activity, and its intratandem mutation, FLT3-ITD, leads to uncontrolled proliferation of myeloblasts and worse outcomes in AML patients. There are currently several pharmacological agents that can inhibit the effect of either the proteins with tyrosine-kinase activity or the mutated FLT3 gene. We present the case of a 68-year-old patient, smoker, with a history of arterial hypertension, chronic obstructive pulmonary disease, presenting with headache unresponsive to antalgics, dyspnea after physical exertion, and epistaxis, with onset 2 months prior to his presentation. The patient was diagnosed with AML with positive FTL3 mutation for which conventional induction therapy was initiated. Within the next days, the patient presented several complications related to the disease itself or caused by the treatment, which eventually led to his death.
