Clinical Characteristics, Risk Factors and Cardiac Manifestations of Cancer Patients with COVID-19 (preprint)

Background: Coronavirus disease 2019 (COVID-19) has been associated with cardiovascular features, which may be deteriorated in cancer patients.Methods: We retrospectively assessed 1,244 COVID-19 patients from February 1st to August 31st (140 cancer and 1104 non-cancer patients). Clinical data and laboratory findings were obtained and compared between cancer and non-cancer groups. Risk factors for in-hospital mortality were identified by multivariable COX regression models.Findings: The median age of cancer group was older than that in non-cancer patients [61 (57-67) vs. 56 (40-68), p < 0.001]. For cancer group, 56% were in severe and critical status, while the proportion was 10% for non-cancer group. Cancer patients had increased levels of leukocyte, neutrophil count and BUN (all p < 0.01), while lymphocyte count was significantly lower (p < 0.001). The most common solid tumor types were gastrointestinal cancer (26%), lung cancer (21%), breast and reproductive cancer (both 19%). There is a rising for cardiac biomarkers, including Pro-BNP, cTnI, MYO, CK-MB, and D-Dimer in COVID-19 cancer population, especially in deceased cancer subjects. The 30-day in hospital mortality in cancer group was dramatically raised than that in non-cancer group (12.9% vs. 4.0%, p<0.01). In multivariable COX regression models, fever, disease severity status, underlying diseases were risk factors for mortality. The Pro-BNP and D-Dimer levels were significantly increased in cancer subjects with cardiovascular disease.Interpretation: COVID-19 cancer patients relate to deteriorating conditions, increased risk of admission to intensive care units and in-hospital mortality. They display severely impaired myocardium, damaged heart function and imbalanced homeostasis of coagulation, which warrants more aggressive treatment.

Serum lipid profile changes and their clinical diagnostic significance in COVID-19 Mexican Patients (preprint)

Background: COVID-19 has been recognized as an emerging and rapidly evolving health condition. For this reason, efforts to determine changes in laboratory parameters of COVID-19 patients as biomarkers are urgent. Lipids are essential components of the human body, and their modulation has been observed implicated in some viral infections. Methods: To evaluate the clinical diagnosis utility of the lipid profile changes in Mexican COVID-19 patients, the lipid profile of one hundred two COVID-19 positive patients from three hospitals in Culiacan, Sinaloa in northwest Mexico, was analyzed. ROC curves and binary logistic regression analysis were used as a predictive model to determine their clinical diagnostic utility. Results: Significant changes in the serum lipid profile of patients with COVID-19, such as low levels of cholesterol, LDL, and HDL, while high triglycerides and VLDL were observed. The same abnormalities in the lipid profile among non-critical and critical COVID-19 patients were detected. The predictive model analysis suggests that cholesterol and LDL have AUC values of 0.710 and 0.769, respectively, for COVID-19 (p= 0.0002 and p= <0.0001), and LDL low levels might be a risk factor for critical COVID-19 (OR= 2.07, 95% IC: 1.18 to 3.63; p= 0.01). Conclusion: Our findings suggest that low cholesterol and LDL levels could be considered an acceptable predictor for COVID-19, and low levels of LDL might be a risk factor for critical COVID-19 patients.
