We attempted the cocktail treatment of favipiravir, steroid, and heparin for COVID-19. This study aimed to evaluate the effect of cocktail therapy for severe COVID-19.The treatment protocol was as follows: oral favipiravir (3600 mg on Day 1, 1600 mg from day 2 to day 14), methylprednisolone (1000 mg for 3 days), and low molecular weight (2000 IU every 12 h) or unfractionated heparin (10,000-12,000 IU/day). Thirteen patients with COVID-19 requiring mechanical ventilation were admitted during the study period. Mean patient age was 63 (range, 46-80) years, and 69.0% were men. Only one patient required extracorporeal membrane oxygenation. Time from first symptom appearance to favipiravir administration was 8.7 (range, 4-13) days. The P/F ratio changed very little over the first 6 days and then gradually recovered. The Interleukin-6 peaked on Day 4 and decreased thereafter. Presepsin also peaked on Day 3, remained about the same until Day 6, and then decreased. The clinical course of SARS-CoV-2 treatment with the cocktail in mechanically ventilated patients with COVID-19 indicated that favipiravir could partially control inflammatory mediators but could not completely control them or respiratory status.
Aim The aim of this study was to investigate the prognostic factors and evaluate the change in inflammatory markers of patients with coronavirus disease 2019 (COVID‐19) requiring mechanical ventilation. Methods This retrospective observational study conducted from April 1, 2020, to February 18, 2021, included 97 adult patients who required mechanical ventilation for severe COVID‐19 pneumonia and excluded nonintubated patients with a positive COVID‐19 polymerase chain reaction test and those who had any obvious bacterial infection on admission. All patients were followed up to discharge or death. We obtained clinical information and laboratory data including levels of presepsin, interleukin‐6, procalcitonin, and severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) antibody every day. Poor outcome was defined as death or receiving a tracheostomy during hospitalization, and favorable outcome was defined as discharge after extubation. Results Differences (median [interquartile range]) were detected in age (76 [70–82] versus 66 [55–74] years), day from the onset of first symptoms to admission for mechanical ventilation (5 [3–7] versus 10 [8–12] days), and P/F ratio (i.e., ratio of arterial oxygen concentration to the fraction of inspired oxygen) after intubation (186 [149–251] versus 236 [180–296]) in patients with poor outcome versus those with favorable outcome on admission. Serum SARS‐CoV‐2 antibody levels had already increased on admission in patients with favorable outcome. We determined the day from the onset of first symptoms to admission for mechanical ventilation to be one of the independent prognostic factors of patients with COVID‐19 (adjusted odds ratio 0.69, confidence interval 0.56–0.85). Conclusion These results may contribute to understanding the mechanism of progression in severe COVID‐19 and may be helpful in devising an effective therapeutic strategy.
Background Many patients with severe COVID-19 have impaired glucose tolerance, and steroid therapy is a standard treatment. Thus, good glycemic control is important and correlates with better patient outcomes. We began using a continuous intravenous insulin infusion protocol for glycemic control whose infusion rate changes based on the currently measured value and previous value. This study aimed to evaluate this protocol for COVID-19 patients requiring mechanical ventilation. Methods This single-center, retrospective, case control study was conducted on all adult patients who required mechanical ventilation for severe COVID-19 pneumonia admitted to our critical care center from April 1, 2020 through June 20, 2021. Blood glucose levels were measured in all patients every 4 h after admission. We started using the insulin infusion protocol from August 1, 2020. Patients before starting the protocol comprised the non-protocol group and those after starting the protocol comprised the protocol group. Blood glucose levels and hypo- or hyperglycemia events were compared between groups. We also surveyed ICU nurses about their experience using the protocol. Results During the study period, 173 patients with COVID-19 were admitted. After 15 patients were excluded for several reasons, the study included 158 patients: non-protocol group (n = 14) and protocol group (n = 144). In the initial phase (days 1–2), blood glucose levels of the protocol group were higher compared with the non-protocol group, and as the number of measurements increased, blood glucose levels were gradually brought under control within the target range in the protocol group. Almost no hypoglycemic events (blood glucose < 80 mg/dL) were detected in either group. The rate of hyperglycemia (blood glucose > 300 mg/dL) was about 5–10% in the initial phase in the protocol group and about 10–15% in the early phase (days 3–4) in the non-protocol group. The questionnaire survey revealed that 80% of ICU nurses responded favorably. Conclusions This insulin protocol gradually brought the blood glucose level within target levels in severe COVID-19 patients treated with high-dose steroid. Some hyperglycemia events were detected despite patients being under the protocol in the initial phase, and thus, minor modifications of the protocol might be required in the initial phase.
