COVID-19-associated pulmonary aspergillosis (CAPA) in hematological patients: Could antifungal prophylaxis be necessary? A nationwide study.

Background: COVID-19-associated pulmonary aspergillosis (CAPA) has emerged as a relatively common complication. Multiple studies described this relationship in critical patients, however its incidence and outcome in other risk groups such as immunosuppressed patients remains unknown. In this sense, we aimed to evaluate the rates and outcomes of CAPA in hematological patients and according to the different hematological malignances, comparing to invasive pulmonary aspergillosis (IPA) in non-COVID-19 ones.

Phase 2 Clinical Trial of Infusing Haploidentical K562-mb15-41BBL-Activated and Expanded Natural Killer Cells as Consolidation Therapy for Pediatric Acute Myeloblastic Leukemia.

Background: Acute myeloid leukemia (AML) accounts for approximately 20% of pediatric leukemia cases; 30% of these patients experience relapse. The antileukemia properties of natural killer (NK) cells and their safety profile have been reported in AML therapy. We proposed a phase 2, open, prospective, multicenter, nonrandomized clinical trial for the adoptive infusion of haploidentical K562-mb15-41BBL-activated and expanded NK (NKAE) cells as a consolidation strategy for children with favorable and intermediate risk AML in first complete remission after chemotherapy (NCT02763475).

Fluctuating neurological symptoms: should I call the neurologist or the hematologist?

Objectives: The objective of this study was to highlight the role of the clinical laboratory and the relevance of reporting the case immediately to the unit of hematology for the diagnosis and early administration of treatment in the presence of such an urgent hematologic disease as thrombotic thrombocytopenic purpura (TTP).

Case Presentation: An elderly patient was referred to the emergency department of our hospital by his general practitioner for speech difficulty, facial asymmetry and weakness in the upper limb. Stroke code was activated.

Clínica neurológica fluctuante: ¿Llamo al neurólogo o al hematólogo?

Objetivos: Resaltar el papel del laboratorio clínico y la pronta comunicación con el servicio de Hematología en el diagnóstico y la rapidez en la instauración del tratamiento de una patología hematológica tan urgente como la Púrpura Trombótica Trombocitopénica (PTT).

Caso ClÍnico: Varón de edad avanzada derivado a Urgencias hospitalarias por su médico de Atención Primaria por trastorno de emisión del lenguaje, asimetría facial y disminución de fuerza en extremidad superior, por lo que se activa el código ictus. Sin embargo, los hallazgos de laboratorio (anemia y trombocitopenia, creatinina, bilirrubina total y LDH elevadas, test de Coombs directo negativo) y presencia de esquistocitos en el frotis de sangre periférica, acaban derivando en un diagnóstico completamente diferente: microangiopatía trombótica tipo PTT.
