Abstract
Severe Acute Respiratory Syndrome CoronaVirus‐2 (SARS‐CoV‐2) infection can result in different clinical manifestations (COVID-19), starting from asymptomatic disease to life threatening respiratory insufficiency. Onco-haematologic patients are at higher risk to develop severe COVID-19. In particular, patients affected by lymphoproliferative diseases, given the impaired cell-mediated and antibody-mediated immunity and treatment toxicity, develop more often a symptomatic and a more serious disease of Covid-19. Various therapeutic and prophylactic agents are being used against COVID‐19 such as antiviral drugs, vaccines and antiviral S‐protein monoclonal antibodies. Pre-exposure prophylaxis with AZD442/Evusheld (tixagevimab-cilgavimab) may be a complementary strategy to decrease the incidence or severity of COVID-19 for patients with B-cell malignancies. Tixagevimab-cilgavimab is a combination of two monoclonal antibodies that bind SARS-CoV-2 spike protein and inhibits the attachment to the surface of cells, preventing viral entry in the cell and COVID-19 development. In the setting of hematology real-life, few data are available on the impact of pre-exposure prophylaxis, given the multiple factors involved in the clinical behavior of SARS-CoV-2 . Our aim was to evaluate the clinical benefit and the safety of this strategy at our center.
期刊介绍:
Reciprocal interdependence between infectious and hematologic diseases (malignant and non-malignant) is well known. This relationship is particularly evident in Mediterranean countries. Parasitosis as Malaria, Leishmaniosis, B Hookworms, Teniasis, very common in the southeast Mediterranean area, infect about a billion people and manifest prevalently with anemia so that they are usually diagnosed mostly by experienced hematologist on blood or bone marrow smear. On the other hand, infections are also a significant problem in patients affected by hematological malignancies. The blood is the primary vector of HIV infection, which otherwise manifest with symptoms related to a reduction in T lymphocytes. In turn, infections can favor the insurgency of hematological malignancies. The causative relationship between Epstein-Barr virus infection, Helicobacter pylori, hepatitis C virus, HIV and lymphoproliferative diseases is well known.
