Abstract
Patients with oncohematological or primary hematological diseases have a higher risk of developing severe forms of COVID-19 and their evolution is unfavorable. General care and immunization with vaccines is the current form of protection for these patients. The presence of post-vaccination IgG antibodies was analyzed in 73 oncohematological adult patients or with immune diseases treated at a regional hospital in Argentina. The patients were immunized with the Sputnik V, AstraZeneca or Sinopharm vaccine. 69% were evaluated after one dose and the rest after two. We observed that 65% of the patients achieved IgG seroconversion. In the analysis of the variables that influenced seroconversion with achieved levels >65% were: age <60 years: 67%; no chemotherapy treatment at the time of analysis: 69%; complete remission of the disease: 67%; two doses: 68% and history of COVID-19 infection prior to vaccination: 83%. However, none of these variables showed a statistically significant difference in a univariate analysis. The anti-SARS-Cov2 vaccination in these patients showed a significant tendency to seroconversion, the main factor being COVID-19 infection prior to vaccination.
