Multiple myeloma and Chagas disease: qPCR as a marker for preemptive antiparasitic therapy: a case reports series and review.

Multiple myeloma (MM) associated with Chagas disease is rarely described. This disease and its therapy suppress T cell and macrophage functions and increase regulatory T cell function, allowing the increase of parasitemia and the risk of Chagas Disease Reactivation (CDR). We aimed to analyze the role of conventional (cPCR) and quantitative Polymerase Chain Reaction (qPCR) for prospective monitoring of T.

Real-world Imatinib Mesylate Treatment in Patients with Chronic Myeloid Leukemia: The Importance of Molecular Monitoring and the Early Molecular Response.

Introduction: Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder characterized by the Philadelphia (Ph) chromosome. After the introduction of imatinib mesylate (IM) in 2000, the natural history of the disease changed. Data on the treatment of CML with IM are from randomized clinical trials.

Systemic amyloidosis journey from diagnosis to outcomes: a twelve-year real-world experience of a single center in a middle-income country.

Background: Systemic amyloidosis is caused by the deposition of misfolded protein aggregates in tissues, leading to progressive organ dysfunction and death. Epidemiological studies originate predominantly from high-income countries, with few data from Latin America. Due to the non-specific clinical manifestations, diagnosing amyloidosis is often challenging and patients experience a long journey and delay in diagnosis.

Diagnosis and treatment of systemic mastocytosis in Brazil: Recommendations of a multidisciplinary expert panel.

Introduction: Systemic Mastocytosis comprises a group of neoplastic diseases characterized by clonal expansion and infiltration of mast cells into several organs. The diagnosis and treatment of this disease may be challenging for non-specialists.

Objective: Make suggestions or recommendations in Systemic Mastocytosis based in a panel of Brazilian specialists.

Brazilian chronic myeloid leukemia working group recommendations for discontinuation of tyrosine kinase inhibitors in chronic myeloid leukemia in clinical practice.

Introduction: Treatment-free remission (TFR) is a new goal of chronic myeloid leukemia (CML) therapy. TFR is feasible when the patient has achieved a deep and stable molecular response and met the criteria required to ensure its success. Treatment discontinuation should not be proposed to the CML patient if minimum conditions are not met.

Associação Brasileira de Hematologia, Hemoterapia e Terapia Celular Consensus on genetically modified cells. IV: CAR-T cell therapy for multiple myeloma patients.

Extraordinary progress has been made over the last decade in the treatment of multiple myeloma with the incorporation of new drugs, particularly proteasome inhibitors, immunomodulators, and monoclonal antibodies. The combined use of innovative drugs, already in the first lines of treatment, has led to an expressive increase in the survival of these patients. However, the approach to relapse remains a great challenge, and the disease continues to be incurable.

Recommendations for the management of cardiovascular risk in patients with chronic myeloid leukemia on tyrosine kinase inhibitors: risk assessment, stratification, treatment and monitoring.

This manuscript summarizes the results of the consensus meeting composed of hematologists and cardiologists to establish recommendations for the prevention and follow-up of cardiovascular (CV) risk in patients with chronic myeloid leukemia (CML) treated with BCR-ABL tyrosine kinase inhibitors (TKIs) from the point of view of clinical practice and from the perspective of hematology consultation. In the first medical appointment, the CV risk factors should be identified to perform the baseline risk stratification, based on the Brazilian Guideline of Dyslipidemia and Atherosclerosis Prevention Update (risk levels: very high, high, intermediate and low). Once stratified, the treatment of the CV risk factors should be administered.

Salvage treatment for refractory or relapsed acute myeloid leukemia: a 10-year single-center experience.

Objectives: The outcomes of refractory and relapsed acute myeloid leukemia (AML) patients in developing countries are underreported, even though the similar classic regimens are widely used.

Methods: We conducted a retrospective comparison of "MEC" (mitoxantrone, etoposide, and cytarabine) and "FLAG-IDA" (fludarabine, cytarabine, idarubicin, and filgrastim) in adults with first relapse or refractory AML.

Results: In total, 60 patients were included, of which 28 patients received MEC and 32 received FLAG-IDA.

Risk factors and incidence of thrombosis in a Brazilian cohort of patients with Philadelphia-negative myeloproliferative neoplasms.

Few data are available regarding epidemiology and outcomes of Philadelphia-negative chronic myeloproliferative neoplasms (MPN) in Latin America. Therefore, current models for MPN treatment are based in large cohorts of patients from Europe and North America. In this paper, we conducted a retrospective study to evaluate thrombotic and bleeding events in a cohort of patients with MPN from a reference center in Brazil.

Iron overload in a teenager with xerocytosis: the importance of nuclear magnetic resonance imaging.

To report a case of iron overload secondary to xerocytosis, a rare disease in a teenager, diagnosed, by T2* magnetic resonance imaging. We report the case of a symptomatic patient with xerocytosis, a ferritin level of 350ng/mL and a significant cardiac iron overload. She was diagnosed by T2* magnetic resonance imaging and received chelation therapy Ektacytometric analysis confirmed the diagnosis of hereditary xerocytosis.
