Hematological- and Immunological-Related Biomarkers to Characterize Patients with COVID-19 from Other Viral Respiratory Diseases
COVID-19 has overloaded health system worldwide; thus, it demanded a triage method for an efficient and early discrimination of patients with COVID-19. The objective of this research was to perform a model based on commonly requested hematological variables for an early featuring of patients with COVID-19 form other viral pneumonia. This investigation enrolled 951 patients (mean of age 68 and 56% of male) who underwent a PCR test for respiratory viruses between January 2019 and January 2020, and those who underwent a PCR test for detection of SARS-CoV-2 between February 2020 and October 2020. A comparative analysis of the population according to PCR tests and logistic regression model was performed. A total of 10 variables were found for the characterization of COVID-19: age, sex, anemia, immunosuppression, C-reactive protein, chronic obstructive pulmonary disease, cardiorespiratory disease, metastasis, leukocytes and monocytes. The ROC curve revealed a sensitivity and specificity of 75%. A deep analysis showed low levels of leukocytes in COVID-19-positive patients, which could be used as a primary outcome of COVID-19 detection. In conclusion, this investigation found that commonly requested laboratory variables are able to help physicians to distinguish COVID-19 and perform a quick stratification of patients into different prognostic categories
Outcomes and clinical characteristics of the compassionate use of plitidepsin for immunocompromised adult patients with COVID-19
Objectives: To evaluate the compassionate use of plitidepsin as an antiviral treatment in hospitalized immunocompromised adult patients with moderate-to-severe COVID-19. Design: Retrospective observational study of data —collected from January 01, 2021 to April 30, 2022— from 35 immunocompromised adult patients with COVID-19 non-eligible for other available antiviral treatments. Main outcome measures were time to respiratory recovery (SpFi ≥ 315); COVID-19-related 30-day-cumulative mortality after first plitidepsin infusion; and time to undetectable levels of viral RNA. Results: Thirty-three patients receiving a full course of plitidepsin (2.5 mg [n = 29] or 1.5 mg [n = 4]) were included. Most (69.7%) had a malignant hematologic disease and 27.3% had solid tumors. A total of 111 infusions were administered with lack of relevant safety events. Median time from plitidepsin initiation to SpFi ≥315 was 8 days (95% confidence interval [CI], 7-19). Median time to first negative reverse transcription-polymerase chain reaction for SARS-CoV-2 (cycle threshold >36) was 17 days (95% CI 13-25). Mortality rate was 16.3% (95% CI 3-37.3). Conclusion: These data support plitidepsin as a well-tolerated treatment that might have potential clinical and antiviral efficacy in COVID-19 immunocompromised patients
