ABSTRACT

Abstract Acute myeloid leukemia (AML) comprises a heterogeneous group of hematopoietic cell neoplasms of myeloid lineage that arise from the clonal expansion of their precursors in the bone marrow, interfering with cell differentiation, leading to a syndrome of bone marrow failure. AML is a consequence of genetic and epigenetic changes (point mutations, gene rearrangements, deletions, amplifications, and arrangements in epigenetic changes that influence gene expression) in hematopoietic precursor cells, which create a clone of abnormal cells that are capable of proliferating but cannot differentiate into mature hematopoietic cells or undergo programmed cell death. The diagnosis requires more than 20% myeloid blasts in the bone marrow and certain cytogenic abnormalities. Treatment will depend on age, comorbidities, and cytogenetic risk among the most frequent.
ABSTRACT
Resumen La infección por coronavirus 2 del síndrome respiratorio agudo grave (SARS-CoV-2) es la causante de la pandemia de enfermedad por coronavirus 2019 (COVID-19), con un índice de letalidad alto. La mayoría de los pacientes graves desarrollan un tipo especial de coagulopatía no descrito hasta ahora y la cual se considera ahora la principal causa de muerte. Por esta razón, el tratamiento anticoagulante se ha convertido en una de las piedras angulares del tratamiento de esta infección. Sin embargo, la velocidad con la que se genera la evidencia respecto al uso de anticoagulantes es muy rápida y, en ocasiones difícil de interpretar y contradictoria. Luego de hacer una revisión extensa de la literatura publicada, se hace esta propuesta para el uso del tratamiento anticoagulante tomando en cuenta los recursos disponibles en México.
Abstract Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is the cause of the coronavirus disease 2019 (COVID-19) pandemic, which has a high case fatality rate. Most severely ill patients develop a special type of coagulopathy that had not been described before and that is now considered the main cause of death. For this reason, anticoagulant treatment has become one of the cornerstones of the treatment of this infection. However, the rate at which the evidence regarding the use of anticoagulants is generated is quite fast, and sometimes it is difficult to interpret and conflicting. After having performed an extensive review of the published literature, this proposal for the use of anticoagulant treatment is made, taking into account available resources in Mexico.
