Abstract Background Thiamine is a precursor of the essential coenzyme thiamine pyrophosphate required for glucose metabolism; it improves the immune system function and has shown to reduce the risk of several diseases. The role of thiamine in critically ill septic patient has been addressed in multiple studies; however, it’s role in COVID-19 patients is still unclear. The aim of this study was to evaluate the use of thiamine as an adjunctive therapy on mortality in COVID-19 critically ill patients. Methods This is a two-center, non-interventional, retrospective cohort study for critically ill patients admitted to intensive care units (ICUs) with a confirmed diagnosis of COVID19. All patients aged 18 years or older admitted to ICUs between March 1, 2020, and December 31, 2020, with positive PCR COVID-19 were eligible for inclusion. We investigated thiamine use as an adjunctive therapy on the clinical outcomes in critically ill COVID-19 patients after propensity score matching. Results A total of 738 critically ill patients with COVID-19 who had been admitted to ICUs were included in the study. Among 166 patients matched using the propensity score method, 83 had received thiamine as adjunctive therapy. There was significant association between thiamine use with in-hospital mortality (OR = 0.39; 95% CI 0.19–0.78; P value = 0.008) as well as the 30-day mortality (OR = 0.37; 95% CI 0.18–0.78; P value = 0.009). Moreover, patients who received thiamine as an adjunctive therapy were less likely to have thrombosis during ICU stay [OR (95% CI) 0.19 (0.04–0.88), P value = 0.03]. Conclusion Thiamine use as adjunctive therapy may have potential survival benefits in critically ill patients with COVID-19. Additionally, it was associated with a lower incidence of thrombosis. Further interventional studies are required to confirm these findings.

Abstract Background: Thiamine is a precursor of the essential coenzyme thiamine pyrophosphate (TPP) required for glucose metabolism; it improves the immune system function and has been shown to reduce the risk of several diseases. The role of thiamine in COVID-19 critically ill patients is still unclear, however, its role in the critically ill septic patient has been addressed in multiple studies. The objective of this study was to evaluate the use of thiamine as adjunctive therapy on the mortality in COVID 19 critically ill patients. Methods: This is a multicenter, non-interventional, retrospective cohort study for all critically ill patients admitted to intensive care units (ICUs) with a confirmed diagnosis of COVID19. All patients aged 18 years or older who were admitted to ICUs between March 1st to December 31st, 2020 with positive PCR COVID-19 were included in the study. We investigated the association between thiamine use as an adjunctive therapy and clinical outcomes in COVID -19 after propensity score matching using baseline severity scores, systemic use of corticosteroids and study centers. Results: A total of 738 critically ill patients with COVID-19 who had been admitted in ICUs at the two governmental hospitals included in the study. Among 166 patients matched using propensity score, 83 had received thiamine as adjunctive therapy. There was significant association between thiamine use with in-hospital mortality (OR=0.49; 95% CI = 0.25- 0.97; P=0.04) as well with 30-day ICU mortality (OR=0.45; 95% CI = 0.215- 0.935; P=0.03). Moreover, patients who received thiamine as an adjunctive therapy were less likely to have thrombosis during ICU stay by 81 % (OR (95%CI): 0.19 (0.040,0.884), p-value=0.034).Conclusion: Thiamine use as an adjunctive therapy may have potential survival benefits in critically ill patients with COVID-19.

Abstract Background Zinc is a trace element that plays a role in stimulating innate and acquired immunity. The role of zinc in critically ill patients with COVID-19 remains unclear. This study aims to evaluate the efficacy and safety of zinc sulfate as adjunctive therapy in critically ill patients with COVID-19. Methods Patients aged ≥ 18 years with COVID-19 who were admitted to the intensive care unit (ICU) in two tertiary hospitals in Saudi Arabia were retrospectively assessed for zinc use from March 1, 2020 until March 31, 2021. After propensity score matching (1:1 ratio) based on the selected criteria, we assessed the association of zinc used as adjunctive therapy with the 30-day mortality. Secondary outcomes included the in-hospital mortality, ventilator free days, ICU length of stay (LOS), hospital LOS, and complication (s) during ICU stay. Results A total of 164 patients were included, 82 patients received zinc. Patients who received zinc sulfate as adjunctive therapy have a lower 30-day mortality (HR 0.52, CI 0.29, 0.92; p = 0.03). On the other hand, the in-hospital mortality was not statistically significant between the two groups (HR 0.64, CI 0.37–1.10; p = 0.11). Zinc sulfate use was associated with a lower odds of acute kidney injury development during ICU stay (OR 0.46 CI 0.19–1.06; p = 0.07); however, it did not reach statistical significance. Conclusion The use of zinc sulfate as an additional treatment in critically ill COVID-19 patients may improve survival. Furthermore, zinc supplementation may have a protective effect on the kidneys.

Abstract Background: Due to its supposed clinical efficacy, relative safety, and low cost, ascorbic acid represents an appealing option for clinicians to utilize in the context of a global health pandemic of COVID-19 patients.Objectives: The aim of this study was to evaluate the efficacy and safety of using ascorbic acid as adjunctive therapy in critically ill patients with COVID-19. Methods: This was a multi-center, non-interventional, retrospective cohort study. All critically ill adult patients admitted to ICU with a confirmed COVID-19 between March 1st to December 31st, 2020 were included in the final analysis. The study was conducted at two large governmental tertiary hospitals in Saudi Arabia. The purpose was to investigate the association between clinical outcomes with ascorbic acid use as an adjunctive therapy in COVID-19 after propensity score matching using baseline severity scores, systemic use of corticosteroids and study centers. Results: A 739 patients were included in this study; 296 patients were included after propensity score matching. There was no association between the administration of ascorbic acid and in-hospital mortality nor 30-day ICU mortality (OR (95%CI): 0.77 (0.476, 1.234), p-value=0.2738 and OR (95%CI): 0.73 (0.438 ,1.204), p-value=0.215 respectively). Using ascorbic acid was associated with lower incidence of thrombosis compared with the non-ascorbic acid group (6.1% vs. 13% respectively); OR (95%CI): 0.42 (0.184, 0.937), p-value=0.0342).Conclusion: Ascorbic acid use as an adjunctive therapy in COVID19 critically ill patients was not associated with mortality benefits; but associated with lower incidence of thrombosis. Further studies are required to confirm these findings.

Abstract Background: Zinc is a trace element that plays a role in stimulating innate and acquired immunity. The role of zinc in critically ill patients with COVID-19 remains unclear. This study aims to evaluate the efficacy and safety of zinc sulfate as adjunctive therapy in critically ill patients with COVID-19.Methods: Patients aged ≥ 18 years with a COVID-19 who were admitted to the intensive care unit (ICU) in two tertiary hospitals in Saudi Arabia were retrospectively assessed for zinc use, from 01 March 2020 until 31-December 2020. We assessed the association of zinc use as adjunctive therapy with the in-hospital and 30-day mortality after propensity score matching. Secondary outcomes included mechanical ventilation (MV) duration, ICU length of stay (LOS), hospital LOS, and complication (s) during ICU stay. Results: A total of 266 patients were included in this study after using propensity score matching. Zinc sulfate as adjunctive therapy during ICU stay was not associated with statistically significant reduction in 30-day mortality nor in-hospital mortality compared to those who did not receive zinc (HR= 0.65 CI = 0.41,1.01; p= 0.05 and HR= 0.67 CI = 0.45,1.00; p= 0.05; respectively). Moreover, MV duration (Beta coefficient 0.10 CI = -0.19,0.39; p= 0.48), ICU LOS (Beta coefficient 0.19 CI = -0.02,0.40; p=0.08) and hospital LOS (Beta coefficient 0.15 CI = -0.02,0.32; p=0.08) were not statistically significant between the two groups. Patients who received zinc have a higher odds of acute kidney injury (AKI) during ICU stay (OR= 1.80 CI = 1.08-3.0; p= 0.02). Conclusion: Zinc sulfate as adjunctive therapy in critically ill patients with COVID-19 may have survival benefit; however, was not statistically significant. Zinc use was linked with an increased risk of AKI development during ICU stay.

Abstract BackgroundRBC-transfusions can be lifesaving, but are also associated with harm. To further examine any effect of red blood cell (RBC)-transfusions given to critically ill patients that were not exposed to the risks of anemia or sepsis, we designed this retrospective propensity score matched study. The aim was to compare mortality and morbidity in non-septic critically ill patients that were given low-grade RBC-transfusions at hemoglobin level > 70 g/L with patients without RBC-transfusions any of the first 5 days in intensive care.MethodsAdult patients admitted to a general 9-bed intensive care unit between 2007-2018 at a tertiary university hospital, were eligible for inclusion. Patients that received > 2 units RBC-transfusion during the first five days after admission, with pre-transfusion hemoglobin level <70 g/L or with severe sepsis or septic shock were excluded. Outcomes were 28-, 90- and 180-day mortality, highest acute kidney injury network (AKIN) score, days alive and free of organ support the first 28 days and highest sequential organ failure assessment score (SOFA-max).ResultsIn total 9491 admissions were recorded during the study period. Propensity score matching at 1:1 ratio resulted in two well matched group with 682 unique patients in each. Median pre-transfusion hemoglobin was 98 g/L (interquartile range 91-106 g/L). Mortality at the measured time points were higher in the RBC-group with an absolute risk increase for death at 180 days of 4.8% [95% confidence interval 2.5 to 7.2%], (p<0.001). Low grade RBC-transfusion was also associated with renal, circulatory and respiratory failure as well as higher SOFA-max score. ConclusionLow-grade leukoreduced RBC-transfusions given to non-septic critically ill patients without significant anemia, was strongly associated with increased mortality, increased kidney-, circulatory- and respiratory- failure as well as with higher SOFA-max score. These findings further strengthen the evidence supporting a restrictive use of RBC-transfusions in critically ill patients.

AbstractAscorbic acid represents an appealing option for clinicians to utilize in the context of the global COVID-19 pandemic due to its proposed clinical efficacy, relative safety, and low cost. The aim of this study was to evaluate the efficacy and safety of using ascorbic acid in supplemental doses as adjunctive therapy for patients critically ill with COVID-19. This was a two-center, non-interventional, retrospective cohort study. All critically ill adult patients admitted to ICU with a confirmed COVID-19 diagnosis between March 1st and December 31st, 2020, were included in the final analysis. The study was conducted at two large governmental tertiary hospitals in Saudi Arabia. The purpose was to investigate the clinical outcomes of low-dose ascorbic acid as adjunctive therapy in COVID-19 after propensity score matching using baseline severity scores, systematic use of corticosteroids, and study centers. A number of 739 patients were included in this study, among whom 296 patients were included after propensity score matching. There was no association between the administration of ascorbic acid and in-hospital mortality or the 30-day mortality [OR (95% CI) 0.77 (0.47, 1.23), p value = 0.27 and OR (95% CI) 0.73 (0.43, 1.20), p value = 0.21, respectively]. Using ascorbic acid was associated with a lower incidence of thrombosis compared with the non-ascorbic-acid group [6.1% vs. 13% respectively; OR (95% CI) 0.42 (0.184, 0.937), p value = 0.03]. Low dose of ascorbic acid as an adjunctive therapy in COVID-19 critically ill patients was not associated with mortality benefits, but it was associated with a lower incidence of thrombosis. Further studies are required to confirm these findings.
