OBJECTIVE: We aimed to develop of a risk stratification model for the pharmaceutical care (PC) of patients with solid or hematologic neoplasms who required antineoplastic agents or supportive treatments. METHOD: The risk stratification model was collaboratively developed by oncology pharmacists from the Spanish Society of Hospital Pharmacy (SEFH). It underwent refinement through three workshops and a pilot study. Variables were defined, grouped into four dimensions, and assigned relative weights...

BACKGROUND AND OBJECTIVES: Elevated serum levels of vitamin B12 have been associated with oncohematological diseases. However, the relevance of its incidental detection in subjects without a previous diagnosis of cancer is unknown. The aim of this study was to evaluate the relationship between incidental hypercobalaminemia (vitamin B12 > 1000 pg/mL) and the diagnosis of a tumor process in patients without a diagnosis and to establish the risk factors. MATERIAL AND METHODS: Retrospective observational study of a cohort of patients with hypercobalaminemia...

BACKGROUND AND OBJECTIVE: IgG replacement therapy (IgG-RT) has radically changed the clinical evolution of primary immunodeficiencies, yet the information regarding secondary hypogammaglobulinemia (SHG) is insufficient or conflicting. We aim to describe clinical features, evolution and treatment of SHG patients in our center. METHODS: Dynamic retrospective cohort between January 2001 and July 2021 of adults with gamma globulin fraction <0.6g/dL in a serum protein electrophoresis and a coincident decrease of IgG levels - with a disease-related SHG or treatment that reduces serum immunoglobulins...

BACKGROUND: Acute myocardial infarction is a major cause of mortality worldwide, and atherosclerotic plaque formation is the main pathophysiological mechanism, which results in chronic inflammation that induces erythrocyte maturation and may cause an increase in the red cell distribution width (RDW) index. OBJECTIVE: Evaluate the role of the anisocytosis index in patients with acute myocardial infarction in both types of infarctions as a predictor of severity. METHODS: Patients were included in the study according to the inclusion/exclusion criteria, following the hospital routine based on their clinical and laboratory history...

OBJECTIVE: Chemotherapy-induced nausea and vomiting continue to pose a significant challenge for patients undergoing hematopoietic stem cell transplantation. This study aims to synthesize available evidence on antiemetic prophylaxis regimens in patients with hematologic malignancies undergoing hematopoietic stem cell transplantation, in order to identify the best standard of care. METHODS: A systematic review will be conducted using MEDLINE via PubMed, EMBASE, ClinicalTrials...

OBJECTIVES: Linezolid is an oxazolidin commonly related to the development of haematological toxicity, being renal clearance the major factor involved in the drug clearance. The aim of this study is to evaluate the influence of increased filtration rates in the incidence of linezolid-induced haematological toxicity by comparing augmented renal clearance (ARC) patients versus normal renal function patients. MATERIAL AND METHODS: A retrospective, observational study was conducted on hospitalized patients treated with linezolid for 5 days or more during 2014-2019 period...

Background: This study aimed to construct a preoperative model predicting lymph node metastasis (LNM) in IB1-IIA2 stage cervical squamous cell cancer (CSCC) based on hematological indexes. Merhods: Between February 2011 and February 2022, 463 patients with IB1-IIA2 stage CSCC underwent radical resection. Patients were allocated to either a model-development cohort (n=337) or a validation cohort (n=126). The final model was determined by comparing different methods of variable selection, and then its discrimination and calibration metrics were evaluated...

When a SARS-CoV-2 RT-qPCR test is performed, it may determine an indirect measure of viral load called cycle threshold (Ct). Respiratory samples with Ct <25.0 cycles are considered to contain a high viral load. We aimed to determine whether SARS-CoV-2 Ct at diagnosis could predict mortality in patients with hematologic malignancies (lymphomas, leukemias, multiple myeloma) who contracted COVID-19. We included 35 adults with COVID-19 confirmed by RT-qPCR performed at diagnosis. We evaluated mortality due to COVID-19 rather than mortality due to the hematologic neoplasm or all-cause mortality...

BACKGROUND: Pregnancy-induced hypertension (PIH) has been related to impaired fetal growth, possibly by affecting hematopoiesis. This study aimed to analyze the most frequent hematological alterations in preterm infants born to mothers with PIH. METHODS: We conducted a cross-sectional study in newborns born to mothers with PIH. We reviewed 130 hemograms of preterm infants: 45 from mothers with PIH, 71 with preeclampsia, and 14 with HELLP syndrome (hemolysis, elevated liver enzymes, and low platelet count)...

BACKGROUND: Several studies to evaluate the accuracy of galactomannan (GM) in bronchoalveolar lavage fluid (BALF) as a diagnostic tool have been carried out; however, there are still controversies about the optimal cut-off point of BALF GM. AIMS: The objective of this study was to determine the diagnostic accuracy and the optimal cut-off point on BALF GM from patients with suspected invasive pulmonary aspergillosis (IPA) in a tertiary care hospital. METHODS: A cross-sectional study with 188 patients (≥18 years) that had undergone a bronchoscopy with BAL due to suspected IPA was carried out...

Introduction: Hemophagocytic lymphohistiocytosis (HHL), a severe hyperinflammatory syndrome caused by aberrant activation of macrophages and cytotoxic T cells, is clinically manifested as a febrile onset along with cytopenias, high ferritin serum level and splenomegaly. In adult patients, secondary causes of it should be looked for, such as autoimmune and infectious diseases and neoplasms. Prompt initiation of treatment is important due to the high mortality of this syndrome. Methods: A case of a 53-year-old patient diagnosed with HHL associated with T-cell lymphoma is presented as a sudden onset of several symptoms and signs of HHL, along with infectious complications...

SARS-CoV-2 infection in patients with hematological malignancies and hematopoietic stem cell transplants (HSCT) can be severe and with significant mortality. We carried out a prospective and observational study to describe the clinical and epidemiological characteristics and outcome of SARS-CoV-2 infection in patients with hematological malignancies and HSCT. Twenty adult patients were included with a median age of 58 years and a median Charlson score of 3. Infections were community-acquired and nosocomial in 60% and 40%, respectively, and 30% of the patients had a history of contact with a SARS-CoV-2 infected person...

Liposomal amphotericin B (L-AmB) has been a key cornerstone for the management of invasive fungal infections (IFI) caused by a wide array of molds and yeasts during the last three decades. Multiple studies performed over this period have generated a large body of evidence on its efficacy and safety, becoming the main antifungal agent in the management of IFI in patients with hematologic malignancies in several not mutually exclusive clinical settings. First, L-AmB is the most commonly used antifungal agent in patients undergoing intensive chemotherapy for acute leukemia and high-risk myelodysplastic syndrome, as well as in hematopoietic stem cell transplant recipients...

The pathophysiology of the inflammatory profile induced by SARS-COV2 infection has similarities with conditions of immune system activation with cytokine release such as hemophagocytic syndrome and some cases of acute graft-versus-host disease. There are encouraging results of clinical studies, performed with increasingly better methodological quality, supporting the use of targeted and specific anti-inflammatory therapy in selected groups of patients with COVID-19 with severe inflammation. In this review we describe the inflammatory pathophysiology of the disease and the recent findings about its treatment...

Introduction: COVID-19 disease is an acute viral pneumonia with multiple extrapulmonary manifestations, including certain hematological alterations. The leukoerythroblastic reaction or leukoerythroblastosis is defined by the presence in peripheral blood of nucleated erythroid cells and immature myeloids. Among its most frequent causes is medullary invasion by solid tumors and hematological neoplasms, so the recognition and consequent study of this reaction is extremely important. To date, only a single case of COVID-19 disease associated with a leukoerythroblastic reaction has been reported worldwide in adult patients...
