Intravenous High-dose Anakinra Drops Venous Thrombosis and Myocardial Infarction in Severe and Critical COVID-19 Patients: A Propensity Score Matched Study (preprint)

Introduction: In our study, we aimed to evaluate the effect of high-dose intravenous anakinra treatment on the development of thrombotic events in severe and critical COVID-19 patients. Material and methods: This retrospective observational study was conducted at a tertiary referral center in Aksaray, Turkey. The study population consisted of two groups as follows; the patients receiving high-dose intravenous anakinra (anakinra group) added to background therapy and the patients treated with standard of care (SoC) as a historical control group. Age, gender, mcHIS scores, and comorbidities such as DM, HT, and CHD of the patients were determined as the variables to be matched. Results: We included 114 patients in SoC and 139 patients in the Anakinra group in the study. Development of any thromboembolic event (5% vs 12.3%, p = 0.038; OR:4.3) and PTE (2.9% vs 9.6%, p = 0.023; OR:5.1) were lower in the Anakinra group than SoC. No patient experienced CVA and/or clinically evident DVT both in two arms. After 1:1 PS matching, 88 patients in SoC and 88 patients in the Anakinra group were matched and included in the analysis. In survival analysis, the development of any thromboembolic event, PTE, and MI were higher in SoC compared to Anakinra. Survival rate was also lower in patients with SoC arm than Anakinra in patients who had any thromboembolic event as well as MI. Conclusion: In our study, the development of thrombosis was associated with hyperinflammation in patients with severe and critical COVID-19. Intravenous high-dose anakinra treatment decreases both venous and arterial events in patients with COVID-19.

Comparison of long-term outcome of patients with ST-segment elevation myocardial infarction between pre-COVID-19 and COVID-19 era.

AIMS: To compare major cardiovascular and cerebrovascular events (MACCE) rates between patients in the pre-COVID-19 era and COVID-19 era, and to assess the impact of the presence of COVID-19 (+) on long-term MACCE in ST-segment elevation myocardial infarction (STEMI) in Turkey. METHODS: Using the TURSER study (TURKISH ST-segment elevation myocardial infarction registry) data, the current study included 1748 STEMI patients from 15 centres in Turkey. Patients were stratified into COVID-19 era (March 11st-May 15st, 2020; n = 723) or pre-COVID-19 era (March 11st-May 15st, 2019; n = 1025) cohorts. Long-term MACCE rates were compared between groups. In addition, the effect of COVID-19 positivity on long-term outcomes was evaluated. The primary outcome was the occurrence of MACCE at long-term follow-up, and the secondary outcome was hospitalization with heart failure. RESULTS: The MACCE and hospitalization with heart failure rates between pre-COVID-19 era and COVID-19 era were 23% versus 22% (p = .841), and 12% versus 8% (p = .002), respectively. In the COVID-19 era, the rates of MACCE and hospitalization with heart failure COVID-19-positive versus COVID-19-negative patients were 40% versus 20%, (p < .001), and 43% versus 11% (p < .001), respectively. CONCLUSION: There was no difference between the pre-COVID-19 era and the COVID-19 era in terms of MACCE  in STEMI patients in Turkey. In the COVID-19 era, STEMI patients positive for COVID-19 had a higher rate of MACCE and heart failure hospitalization at the long-term follow-up.

High Dose Intravenous Anakinra Treatment is Safe and Effective in Severe and Critical COVID-19 Patients: A Propensity Score Matched Study in a Single Center (preprint)

Background: In COVID-19 severe disease course such as need of intensive care unit (ICU) as well as development of mortality is mainly due to cytokine storm. In this study, we aimed to evaluate the high dose intravenous anakinra treatment response and outcome in patients with severe and critically ill COVID-19 compared to standard of care. Method : This retrospective observational study was carried out at a tertiary referral center. The study population consisted of two groups as follows; the patients receiving high dose intravenous anakinra (anakinra group) between 01.09.2021 and 01.02.2022 and the patients treated with standard of care (SoC, control group) as historical control group who were hospitalized between 01.07.2021 and 01.09.2021. Results:After the propensity score 1:1 matching 79 patients in anakinra and 79 patients in SoC matched and included into the analysis. Mean±SD patient age was 67.4±16.7 and 67.1±16.3 years in anakinra and SoC group, respectively (p=0.9). Male gender was 38 (48.7 %) in anakinra and 36 (46.2 %) SoC (p=0.8). Overall, ICU admission was in 14.1 % (n=11) and 30.8 % (n=24) (p=0.013; OR: 6.2), intubation in 12.8 % (n=10) and 16.7 % (n=13) patients (p=0.5), 14.1 % (n=11) and 32.1 % (n=25) patients died in anakinra and control group, respectively (p=0.008; OR: 7.1) Conclusion : In our study mortality was lower in patients receiving anakinra compared to SoC. Intravenous high dose anakinra is safe and effective treatment in patients with severe and critical COVID-19.

Impact of COVID-19 outbreak on patients with ST-segment elevation myocardial infarction (STEMI) in Turkey: results from TURSER study (TURKISH St-segment elevation myocardial infarction registry).

OBJECTIVE: We aimed to investigate both the impact of COVID-19 pandemic on ST-segment elevation myocardial infarction (STEMI) admission, and demographic, angiographic, procedural characteristics, and in-hospital clinical outcomes of patients with COVID-19 positive STEMI in Turkey. METHODS: This was a multi-center and cross-sectional observational study. The study population included 1788 STEMI patients from 15 centers in Turkey. The patients were divided into two groups: COVID-19 era (March 11st-May 15st, 2020; n = 733) or pre- COVID-19 era group (March 11st-May 15st, 2019; n = 1055). Also, the patients in COVID-19 era were grouped as COVID-19 positive (n = 65) or negative (n = 668). RESULTS: There was a 30.5% drop in STEMI admission during COVID-19 era in comparison to pre-COVID-19 era. The patients admitted to the medical centers during COVID-19 era had a longer symptom-to-first medical contact time [120 (75-240) vs. 100 (60-180) minutes, p < 0.001]. COVID-19 positive STEMI patients had higher thrombus grade and lower left ventricular ejection fraction compared to COVID-19 negative patients. COVID-19 positive patients had higher mortality (28% vs. 6%, p < 0.001) and cardiogenic shock (20% vs. 7%, p < 0.001) rates compared with those without COVID-19. Matching based on propensity scores showed higher mortality and high thrombus grade in STEMI patients who were infected by SARS-COV-2 (each p < 0.05). CONCLUSIONS: We detected significantly lower STEMI hospitalization rates and significant delay in duration of symptom onset to first medical contact in the context of Turkey during the COVID-19 outbreak. Moreover, high thrombus grade and mortality were more common in COVID-19 positive STEMI patients.

Prognostic value of D-dimer/fibrinogen ratio on in-hospital outcomes of patients with heart failure and COVID-19.

Aim: In the present study, the relationship between D-dimer/fibrinogen ratio (DFR) and in-hospital outcomes was evaluated in patients with COVID-19 and a diagnosis of heart failure (HF). Materials & methods: In-hospital outcomes were compared in patients with high and low DFR values. Results: With regard to in-hospital outcomes, patients in the third tertile of DFR had a higher rate of mechanical ventilation, cardiogenic shock and death (p < 0.001). The length of ICU stay was longer in the third tertile group (p < 0.001). When evaluated together with infection markers, DFR was found to be an independent predictor of outcomes. Conclusion: DFR can be used as a prognostic marker in patients with COVID-19 with a diagnosis of HF, and perhaps more valuable than other infection markers.

Clinical characteristics and in-hospital outcomes of COVID-19 patients with history of heart failure: a propensity score-matched study.

BACKGROUND: Data on the clinical course and outcomes of COVID-19 disease among patients with a history of heart failure (HF) are scarce. Therefore, the aim of this study was to assess the clinical characteristics, prognostic biomarkers and in-hospital outcomes of patients with a history of HF hospitalised with confirmed COVID-19. METHODS: A total of 8321 consecutive patients hospitalised with suspected COVID-19 disease were screened. Furthermore, 3849 patients with laboratory-confirmed SARS-CoV-2 infection were included in the study. Two hundred and forty COVID-19 patients with a history of HF and 240 without HF paired with PSM were evaluated. RESULTS: Mean age was 72.7 ± 9.90 years, and 64.6% were men. Oxygen saturation, systolic and diastolic blood pressure at admission were significantly lower and heart rate was significantly higher in patients with a history of HF compared to those without. Patients with HF, compared to those without, had significantly higher leukocyte count, D-dimer, CRP, procalcitonin, hsTnI, lactate and lower albumin and lymphocyte. Compared with patients without HF, those with previous HF had a longer length of stay at ICU (6.22 d vs. 3.71 d; p < 0.001), increased risk of mechanical ventilation (42.1% vs. 15.4%; p < 0.001), in-hospital death (39.2% vs. 15.4%; p < 0.001) and composite outcomes (52.9% vs. 17.1%; p < 0.001). CONCLUSION: History of HF is associated with a higher risk of mechanical ventilation, cardiogenic shock, mortality and longer ICU stay in patients hospitalised for COVID-19, therefore the diagnosis of HF alone is important for predicting clinical outcomes.
