ABSTRACT
La enfermedad del coronavirus 2019 (COVID-19) causada por la infección por el nuevo coronavirus (SARS-CoV-2) ha creado una pandemia que ha llevado a una lucha mundial para hacer frente al gran número de personas infectadas, muchas de las cuales requieren cuidados intensivos. Hasta la fecha, no existe un tratamiento antivirus específico para COVID-19. El uso de transfusiones de plasma de convalecientes podría ser de gran valor en la pandemia actual. Los pacientes con SRAS-CoV-2 recuperados recientemente que pueden ser donantes adecuados se someten a aféresis para obtener plasma de convalecencia que contenga anticuerpos con títulos elevados, siempre que cumplan los criterios de donación de sangre. En esta revisión, resumimos la literatura existente sobre el plasma convaleciente como una opción terapéutica para COVID-19. Es importante señalar que es necesario estudiar más a fondo el momento adecuado para la administración de plasma de convalecencia y la gravedad de sus efectos adversos. El plasma de convalecencia ofrece la posibilidad de convertirse en una opción de tratamiento prometedora inmediata al evaluar los medicamentos existentes y desarrollar nuevas vacunas y terapias específicas.
The coronavirus disease 2019 (COVID-19) caused by novel coronavirus (SARS-CoV-2) infection has created a pandemic leading to a global struggle to cope with the sheer numbers of infected persons, many of whom require intensive care support. To date, there is no specific antivirus treatment for COVID-19. The use of convalescent plasma transfusions could be of great value in the current pandemic. Recently recovered SARS-CoV-2 patients who may be suitable donors undergo apheresis in order to obtain convalescent plasma containing high-titer antibodies, granted they meet blood donation criteria. In this review, we summarize existing literature around convalescent plasma as a therapeutic option for COVID-19. It is important to note that the appropriate timing on convalescent plasma administration and the severity of its adverse effects needs to be further studied. Convalescent plasma provides the potential to render an immediate promising treatment option while evaluating existing drugs and developing new specific vaccines and therapies.
ABSTRACT
The different types of Ph-negative myeloproliferative neoplasm(MPN) possess the same JAK2V617 F mutation. JAK2 inhibitor, ruxolitinib, is only valid in some of MPN, which indicates JAK2 target is not the only molecular pathway of MPN. Epigenetic genes mutations, including TET2 and ASXL1, are involved in the progression and transformation of MPN. In addition, avoiding thromboembolism and reducing the risk of transformation into acute leukemia(AL) or myelofibrosis(MF) still is the therapeutic goal of polycythemia vera(PV) and essential thrombocytosis(ET). The goal of treatment in primary myelofibrosis(PMF) is to improve the quality of life and prolong the survival of patients. For the patients with PMF, stratification based on the efficacy of ruxolitinib and profound genetic detection is a reasonable supplement to the existing of stratification of clinical risk.
