Hypertriglyceridemia in Critically Ill Patients With SARS-CoV-2 Infection.

BACKGROUND: Patients with SARS-CoV-2 infection could develop severe disease requiring critical care admission. Case reports indicated high incidence of hypertriglyceridemia (HTG) in critically ill patients infected with SARS-CoV-2, which might be related to the drugs. OBJECTIVE: We sought to determine the risk factors associated with HTG in this population and to investigate the relationship between HTG and lipase. METHODS: A retrospective observational study was conducted at our hospital between March 1 and June 30, 2020. Patients were included if they were ≥18 years old, admitted to the intensive care unit (ICU), tested positive for SARS-CoV-2, and had triglycerides (TG) checked during their hospital stay. RESULTS: Of the 111 critically ill patients, 103 patients were included. Males comprised 88.3% of the sample. The median TG at baseline was 197.4 (IQR: 139.8-283) mg/dL. The lipase median level at baseline was 23.00 (IQR: 0.00-69.50) IU/L. The results of the mixed-effects logistic regression analysis indicated that patient-level variables, favipiravir use, blood glucose level, and propofol use were significantly associated with HTG. There was no relationship between lipase and TG levels over time. Furthermore, TG concentrations over time showed a similar trend to inflammatory markers. CONCLUSION AND RELEVANCE: The incidence of clinically significant HTG was high and was associated with propofol and favipiravir use. HTG might reflect the high inflammatory state in these patients. Clinicians should look at the full picture before changing therapies based only on HTG. Our findings need to be replicated in a larger prospective study.

Thromboelastography findings in critically ill COVID-19 patients.

The rate of venous and arterial thrombotic events among patients infected with severe acute respiratory syndrome coronavirus-2 (SAR-CoV-2) is high. This may be due to a hypercoagulable state induced by the severe inflammation that results from the SAR-CoV-2 infection. We aimed to determine hypercoagulable states' incidence based on thromboelastography study and its association with thrombotic events in critically ill patients with coronavirus disease 2019 (COVID-19). Fifty-two COVID-19 patients who had thromboelastography study were retrospectively included. All patients received pharmacologic thromboprophylaxis. The hypercoagulable state was observed in 16 patients (30.8%). Among them, maximum amplitude and a-angle were elevated in 75% and 25%, respectively. Reaction time and K were low in only 12.5% for both of them. Inflammatory and coagulation markers, as well as thromboprophylaxis regimens, were not associated with a hypercoagulable state. Fourteen patients (27%) experienced a total of 16 thrombotic events, including 8 (57%) deep venous thrombosis, 6 (43%) pulmonary embolism, and 2 (14.3%) arterial thrombosis. The hypercoagulable state was not significantly associated with thrombotic events. In summary, we observed a lower rate of hypercoagulable state on thromboelastography study in critically ill COVID-19 patients. Also, the hypercoagulable state was not associated with the occurrence of thrombotic events.

Treatment of severe pneumonia due to COVID-19 with peginterferon alfa 2a.

The outbreak of the new coronavirus disease 2019 (COVID-19) has spread rapidly worldwide. Until now, no definite effective treatment has been identified. We reported 3 patients with severe COVID-19 treated with pegylated interferon alfa 2a with satisfactory recovery. Based on these observations, randomized studies with interferons should be considered in deteriorating patients infected with COVID-19.

Major bleeding with apixaban in atrial fibrillation: patient characteristics, management, and outcomes.

OBJECTIVES: To identify patient characteristics, bleed management, and bleed outcomes in patients experiencing an apixaban major bleeding event and to identify opportunities to improve the safe use of apixaban. METHODS: This retrospective single health-system study identified apixaban patients experiencing a major bleeding event between January 2013 and May 2016 through electronic medical record review. Patient characteristics, bleed management, and outcomes were extracted in those with a confirmed major bleed assessed by the International Society on Thrombosis and Haemostasis criteria. RESULTS: Fifty major bleeding events occurred in 49 patients (79 ± 9.8 years). Patient characteristics included history of hypertension (94%), anemia (68%), and concomitant antiplatelet use (68%). Gastrointestinal bleeding occurred in 72% of patients and intracranial hemorrhage in 14% of patients. Packed red blood cells (PRBCs) were utilized in 82% of patients and reversal agents were administered to 6% of patients. Mortality during the hospital admission for the bleed was 0%. Anticoagulation was held at discharge in 64% of patients and remained held at 30 days in the majority of patients. Of those on concurrent aspirin therapy, an appropriate indication was not found in 64.7% of patients. CONCLUSIONS: Patients with major bleeding were elderly and frequently on inappropriate concomitant antiplatelet therapy. The majority of patients were managed with PRBC transfusion. More than half of patients had anticoagulation therapy held at discharge. Concerns with prescribing and patient management were identified leading to recommendations for improving the safe use of apixaban therapy.

Cement pulmonary embolism as a complication of percutaneous vertebroplasty in cancer patients.

BACKGROUND: Vertebroplasty is a minimally invasive procedure commonly performed for vertebral compression fractures secondary to osteoporosis or malignancy. Leakage of bone cement into the paravertebral venous system and cement pulmonary embolism (cPE) are well described, mostly in patients with osteoporosis. Little is known about the clinical sequelae and outcomes in cancer patients. In this study, we report our experience with cPE following vertebroplasty performed in cancer patients. METHODS: Records of all consecutive cancer patients who underwent vertebroplasty at our institution were retrospectively reviewed. The procedure was performed via percutaneous injection of barium-opacified polymethyl-methacrylate cement. RESULTS: A total of 102 cancer patients with a median age of 53 (19-83) years were included. Seventy-eight (76.5%) patients had malignant vertebral fractures, and 24 (23.5%) patients had osteoporotic fractures. Cement PE was detected in 13 (12.7%) patients; 10 (76.9%) patients had malignant fractures, and the remaining three had osteoporotic fractures. Cement PE was mostly asymptomatic; however, 5 (38.5%) patients had respiratory symptoms that led to the diagnosis. Only the five symptomatic patients were anticoagulated. Cement PE was more common with multiple myeloma (MM); it occurred in 7 (18.9%) of the 37 patients with MM compared with only three (7.3%) of the 41 patients with other malignancies. No difference in incidence was observed between patients with osteoporotic or malignant vertebral fractures. CONCLUSIONS: Cement PE is a relatively common complication following vertebroplasty and is mostly asymptomatic. Multiple myeloma is associated with the highest risk. Large-scale prospective studies can help identify risk factors and clinical outcomes and could lead to better prevention and therapeutic strategies.
