ABSTRACT
INTRODUCTION: Covid Convalescent Plasma (CCP) failed to demonstrate its efficacy in severe and life-threatening coronavirus disease 2019 (COVID-19) cases. However, the role of CCP in hospitalized moderate cases is unclear. This study aims to examine the efficacy of administering CCP to hospitalized moderate coronavirus disease 2019 patients. METHODOLOGY: An open-label randomized controlled clinical trial design was used from November 2020 - August 2021 at two referral hospitals in Jakarta, Indonesia, and the primary outcome was mortality at 14 days. The secondary outcomes were mortality at 28 days, the time-to-discontinuation of supplemental oxygen, and the time-to-hospital discharge. RESULTS: This study recruited 44 subjects, and the intervention arm consisted of 21 respondents who received CCP. The control arm consisted of 23 subjects who received standard-of-care treatment. All subjects survived during the fourteen-day follow-up period, and the 28-day mortality rate in the intervention group was lower than the control (4.8% vs 13.0%; p = 0.16, HR = 4.39 (95% CI = 0.45-42.71). There was no statistically significant difference in the time-to-discontinuation of supplemental oxygen and time-to-hospital discharge. During the total follow-up period (41 days), the mortality rate in the intervention group was also lower than the control (4.8% vs 17.4%, p = 0.13, HR = 5.47, 95% CI = 0.60-49.55). CONCLUSIONS: This study concluded that in hospitalized moderate COVID-19 patients, CCP did not reduce 14-day mortality compared to the control. Mortality during 28 days and total length of stay (41 days) were lower in the CCP group compared to the control, although they did not reach statistical significance.

Background: In the era of coronavirus disease 2019 (COVID-19), it is mandatory to identify vulnerable people with cancers as they have impaired immune system that can lead to high mortality. This study analyzes the complete blood count (CBC) derived inflammatory biomarkers and the level of anti-SARS-CoV-2 neutralizing antibody (NAb) and spike protein's receptor-binding domain immunoglobulin G (S-RBD IgG) among cancer survivors. Methods: A cross-sectional study was conducted in patients with either solid or hematological cancers who had received two-doses of COVID-19 vaccinations within six months. Results: From 119 subjects, the COVID-19 vaccines demonstrated laboratory efficacy (median NAb=129.03 AU/mL;median S-RBD IgG=270.53 AU/mL). The seropositive conversion of NAb reached 94.1% and S-RBD IgG reached 93.3%. Additionally, the S-RBD IgG had very weak correlation with absolute monocyte count (R=-0.185;p-value=0.044). The NAb also had very weak correlation with leukocyte (Kendall's tau-b (τb)=-0.147;p-value=0.019), absolute neutrophil count (τb=-0.126;p-value=0.044), absolute eosinophil count (τb=-0.132;p-value=0.034). Conclusion: The seropositivity rate of anti-SARS-CoV-2 NAb and S-RBD IgG were significantly high. However, the CBC derived inflammatory biomarkers had poor correlation with anti-SARS-CoV-2 NAb and S-RBD IgG. Thus, anti-SARS-CoV-2 NAb and S-RBD IgG are currently the only reliable markers for measuring the COVID-19 vaccine efficacy which should be widely accessible.
