Curative Strategy for High-Risk Smoldering Myeloma: Carfilzomib, Lenalidomide, and Dexamethasone (KRd) Followed by Transplant, KRd Consolidation, and Rd Maintenance.

Purpose: Early treatment of high-risk smoldering myeloma has been shown to delay progression to multiple myeloma (MM). We conducted this trial with curative intention using a treatment approach employed for newly diagnosed patients with MM.

Methods: Patients with high-risk smoldering myeloma (>50% progression risk at 2 years) and transplant candidates were included and received induction therapy with carfilzomib, lenalidomide, and dexamethasone (KRd), six cycles, followed by high-dose melphalan (200 mg/m) autologous stem-cell transplantation (HDM-ASCT), two KRd consolidation cycles, and Rd maintenance for 2 years.

Recommendations for the diagnosis and treatment of patients with thrombotic thrombocytopenic purpura.

Thrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathy (TMA) characterized by the development of microangiopathic haemolytic anaemia, thrombocytopenia, and ischaemic organ dysfunction associated with ADAMTS13 levels lower than 10% in most cases. Recently there have been numerous advances in the field of PTT, new, rapid and accessible techniques capable of quantifying ADAMTS13 activity and inhibitors. The massive sequencing systems facilitate the identification of polymorphisms in the ADAMTS13 gene.

Consensus document for the diagnosis and treatment of pyruvate kinase deficiency.

Pyruvate kinase (PK) deficiency is the second most frequent enzymopathy and the most common cause of chronic hereditary non-spherocytic haemolytic anaemia. Its global prevalence is underestimated due to low clinical suspicion of mild cases, associated with difficulties in the performance and interpretation of PK enzymatic activity assays. With the advent of next generation sequencing techniques, a better diagnostic approach is achieved.

Impact of hematologic malignancy and type of cancer therapy on COVID-19 severity and mortality: lessons from a large population-based registry study.

Background: Patients with cancer have been shown to have a higher risk of clinical severity and mortality compared to non-cancer patients with COVID-19. Patients with hematologic malignancies typically are known to have higher levels of immunosuppression and may develop more severe respiratory viral infections than patients with solid tumors. Data on COVID-19 in patients with hematologic malignancies are limited.

Prognostic implications of Anemia in patients with acute heart failure in emergency departments. ANEM-AHF Study.

Introduction: The presence of anaemia leads to a worse prognosis in patients with heart failure (HF). There are few data on the impact of anaemia on mortality in patients with acute heart failure (AHF), and the studies available are mainly retrospective, and include hospitalised patients.

Objective: Evaluate the role of anaemia on 30-day and 1-year mortality in patients with AHF attended in hospital emergency departments (HEDs).

Executive summary of the consensus document of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), the Spanish Network for Research in Infectious Diseases (REIPI) and the Spanish Society of Haematology and Haemotherapy (SEHH) on the management of febrile neutropenia in patients with hematological malignancies.

Febrile neutropenia is a very common complication in patients with hematological malignancies receiving chemotherapy, and is associated with high morbidity and mortality. Infections caused by multidrug-resistant bacteria have become a therapeutic challenge in this high-risk patient population, since inadequate initial empirical treatment can seriously compromise prognosis. However, reducing antimicrobial exposure is one of the most significant cornerstones in the fight against resistance.

C3G, through its GEF activity, induces megakaryocytic differentiation and proplatelet formation.

Background: Megakaryopoiesis allows platelet formation, which is necessary for coagulation, also playing an important role in different pathologies. However, this process remains to be fully characterized. C3G, an activator of Rap1 GTPases, is involved in platelet activation and regulates several differentiation processes.

Perioperative and Periprocedural Management of Antithrombotic Therapy: Consensus Document of SEC, SEDAR, SEACV, SECTCV, AEC, SECPRE, SEPD, SEGO, SEHH, SETH, SEMERGEN, SEMFYC, SEMG, SEMICYUC, SEMI, SEMES, SEPAR, SENEC, SEO, SEPA, SERVEI, SECOT and AEU.

During the last few years, the number of patients receiving anticoagulant and antiplatelet therapy has increased worldwide. Since this is a chronic treatment, patients receiving it can be expected to need some kind of surgery or intervention during their lifetime that may require treatment discontinuation. The decision to withdraw antithrombotic therapy depends on the patient's thrombotic risk versus hemorrhagic risk.

[Spanish consensus statement for diagnosis and treatment of paroxysmal nocturnal haemoglobinuria].

Paroxysmal nocturnal haemoglobinuria (PNH) is an acquired clonal disorder of the haematopoietic progenitor cells due to a somatic mutation in theX-linked phosphatidylinositol glycan class A gene. The disease is characterized by intravascular haemolytic anaemia, propensity to thromboembolic events and bone marrow failure. Other direct complications of haemolysis include dysphagia, erectile dysfunction, abdominal pain, asthenia and chronic renal failure (65% of patients).

Hb La Coruña [beta38(C4)Thr-->Ile]: a new hemoglobin variant leading to familial polycythemia.

Hb La Coruña [beta38(C4)Thr --> Ile] is a new hemoglobin (Hb) variant that has an increased oxygen affinity. Clinically, this Hb leads to erythrocytosis. Hb La Coruña is an electrophoretically silent variant that can be detected by reversed phase high performance liquid chromatography (HPLC) and characterized by DNA sequencing.

The first case of Hb E-Saskatoon associated with Hb Lepore-Baltimore found in Spain.

Hb E-Saskatoon [beta22(B4)Glu-->Lys] does not cause any clinical symptoms in the heterozygous state. The homozygous state shows moderate phenotype expression. It has also been detected in association with beta-thalassemia.

[Study of deferoxamine in subcutaneous profusion treatment of iron overload in myelodysplastic syndromes].

Background And Objective: The progressive accumulation of iron in the organism contribute to one of the most important problems of morbidity and mortality in patients with myelodysplastic syndrome (MDS). We present an observational protocol, multicentre, open and non-aleatheorised, in patients diagnosed with MDS on transfusional regime with iron overload. The study was meant to prove the effectiveness of the parenteral treatment with desferrioxamine using continuous devices of subcutaneous profusion and evaluate the evolution of iron overload as well as transfusional requirements.

[Value of analyzing reticulocyte subpopulations in polycythemia].

Objective: The evaluation of the RNA content in reticulocytes by means of flow cytometry allows us to differentiate three reticulocyte populations by their degree of maturity: LFR, MFR and HFR. We have studied the value of those reticulocyte subpopulations for the differential diagnosis in polycythemia.

Patients And Methods: We have studied 25 polycythemia patients, 12 of these were diagnosed of polycythemia vera (PV) and 13 of secondary polycythemia (PS).

[Second neoplasms as a late complication of the treatment of Hodgkin's disease].

Purpose: To determine the incidence of a second malignancy in patients with Hodgkin's disease (HD) diagnosed and treated in the same hospital.

Patients And Methods: A retrospective study was performed on 99 patients diagnosed and treated for HD in the Hospital San Carlos, in Madrid, between January 1976 and december 1987. The clinical records were revised; the diagnosis and staging followed the Rye and Ann Arbor criteria, and the treatment included radiation therapy (RT), chemotherapy (CT), or a combination of both.
