Abstract Background: Dyslipidemia plays an important role in the pathogenesis and evolution of critical illness, but limited information exists regarding the lipid metabolism of severe coronavirus disease 2019 (COVID-19) patients. The aim of this study was to investigate role of dyslipidemia in patients with severe COVID-19Methods: We retrospectively reviewed 216 severe COVID-19 patients with clarified outcomes (discharged or deceased), admitted to the West Court of Union Hospital in Wuhan, China, between February 1 and March 31, 2020. The dynamic changes of lipid profiles and their relationships with disease severity and clinical outcomes were analyzed.Results: A total of 216 severe COVID-19 patients, including 24 non-survivors and 192 survivors, were included in the final analyses. The levels of high-density lipoprotein cholesterol (HDL-C) and apolipoprotein AI (Apo-AI) on admission were significantly lower in non-survivors compared to survivors. During hospitalization, low-density lipoprotein cholesterol (LDL-C), total cholesterol(TC), HDL-C and Apo-AI were shown an increasing trend in survivors, but maintained lower levels or shown downward trend in non-survivors. The serum levels of HDL-C and Apo-AI were inversely correlated with C-reactive protein (CRP), length of hospital stay of survivors and disease severity. The receiver operating characteristic (ROC) curve analysis identified a CRP/ HDL-C ratio cut-off value of 62.54 as the predictor for in-hospital mortality (AUC=0.823, Sensitivity=83.3%, Specificity=70.8%). Logistic regression analysis demonstrated that hypertension, neutrophils-to-lymphocytes ratio(NLR), platelet count and high CRP/ HDL-C ratio (>62.54) were independent factors to predict in-hospital mortality.Conclusions: The results demonstrated that dyslipidemia was associated with the inflammatory response, disease severity and poor prognosis of COVID-19. High CRP/ HDL-C ratio may serve as an independently potential predictor for hospital mortality among patients with severe COVID-19.

Abstract Background The outbreak of the novel coronavirus SARSCoV-2 (coronavirus disease 2019; COVID-19) has spread to most of countries in the world. The tight relationship of plasma lipids and COVID-19 pneumonia (NCIP-19) has not been well invested. To observe lipid profiles and their alterations in hospitalized patients with COVID-19 and evaluated the prognostic value of lipids for the length of hospital stay (LOS). Methods 248 NCIP-19 cases aged 18 years or older were enrolled in this study. Serum lipids, including triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were detected at admission. In 68 severe cases, levels of serum lipids were subsequently detected every 5 ~ 10 days. Results At admission, median levels of TG, TC, HDL-C, and LDL-C in all patients, were 1.11 mmol/L, 4.00 mmol/L, 0.89 mmol/L and 2.11 mmol/L, respectively. Compared with common cases (n = 174), higher TG and HDL-C, lower LDL-C were observed in severe cases (n = 74). Levels of TC and LDL-C at admission were negatively correlated with LOS. In severe cases, the average levels of serum lipids were lowest at admission and gradually increased during hospitalization. Compared with the LOS ≤ 29d group, serum levels of TC, HDL-C, and LDL-C were significantly lower in the LOS > 29d group at admission; this lower trend always existed during the following tests for TC and LDL-C, but not for HDL-C and TG. Patients with LDL-C ≥ 1.70 mmol/L at admission showed a lower risk of LOS prolongation (adjusted HR = 0.557, 95% CI: 0.409–0.759, p < 0.001). Conclusions In NCIP-19, serum lipid levels were low at admission. Levels of TC and LDL-C at admission were negatively correlated with LOS. LDL-C < 1.7 mmol/L at admission may act as the independent predictor of LOS prolongation. In severe cases, the gradual increase of TC, LDL-C, and HDL-C during the hospitalization might indicate the gradual recovery of the disease.

ABSTRACT: CONTEXT AND OBJECTIVE: Red grape seed extract (RGSE) contains oligomeric proanthocyanidin complexes as a class of flavonoids. These compounds are potent antioxidants and exert many health-promoting effects. This study aimed to determine the effects of RGSE on serum levels of triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein AI (apo-AI) levels and paraoxonase (PON) activity in patients with mild to moderate hyperlipidemia (MMH). DESIGN AND SETTINGS: A randomized double-blind placebo-controlled clinical trial was conducted at Shahid-Modarres Hospital (Tehran, Iran) and Tabriz University of Medical Sciences. Seventy MMH patients were randomly assigned to receive treatment (200 mg/day of RGSE) or placebo for eight weeks. RESULTS: Significant elevation in serum levels of apo-AI (P = 0.001), HDL-C (P = 0.001) and PON activity (P = 0.001) and marked decreases in concentrations of TC (P = 0.015), TG (P = 0.011) and LDL-C (P = 0.014) were found in the cases. PON activity was significantly correlated with apo-AI (r = 0.270; P < 0.01) and HDL-C (r = 0.45; P < 0.001). Significant differences between the RGSE and control groups (before and after treatment) for TC (P = 0.001), TG (P = 0.001), PON (P = 0.03), apo-AI (P = 0.001) and LDL-C (P = 0.002) were seen. CONCLUSION: It is possible that RGSE increases PON activity mostly through increasing HDL-C and apo-AI levels in MMH patients. It may thus have potential beneficial effects in preventing oxidative stress and atherosclerosis in these patients.

Glucose And Lipid Metabolism

The effectiveness of anthocyanins may differ according to their chemical structures; however, randomized clinical controlled trials (RCTs) or meta-analyses that examine the consequences of these structural differences have not been reported yet. In this meta-analysis, anthocyanins in test foods of 18 selected RCTs were categorized into three types: cyanidin-, delphinidin-, and malvidin-based. Delphinidin-based anthocyanins demonstrated significant effects on triglycerides (mean difference (MD): −0.24, p < 0.01), low-density lipoprotein cholesterol (LDL-C) (MD: −0.28, p < 0.001), and high-density lipoprotein cholesterol (HDL-C) (MD: 0.11, p < 0.01), whereas no significant effects were observed for cyanidin- and malvidin-based anthocyanins. Although non-significant, favorable effects on total cholesterol (TC) and HDL-C were observed for cyanidin- and malvidin-based anthocyanins, respectively (both p < 0.1). The ascending order of effectiveness on TC and LDL-C was delphinidin-, cyanidin-, and malvidin-based anthocyanins, and the differences among the three groups were significant (both p < 0.05). We could not confirm the significant effects of each main anthocyanin on glucose metabolism; however, insulin resistance index changed positively and negatively with cyanidin- and delphinidin-based anthocyanins, respectively. Therefore, foods containing mainly unmethylated anthocyanins, especially with large numbers of OH groups, may improve glucose and lipid metabolism more effectively than those containing methylated anthocyanins.

OBJECTIVE: The present study aimed to evaluate the effect of feeding diets enriched with fatty fish from the Amazon basin on lipid metabolism. METHODS: Male Wistar rats were divided into four groups: control group treated with commercial chow; Mapará group was fed diet enriched with Hypophthalmus edentatus; Matrinxã group was fed diet enriched with Brycon spp.; and, Tambaqui group was fed diet enriched with Colossoma macropomum. Rats with approximately 240g±0.60 of body weight were fed ad libitum for 30 days, and then were sacrificed for collection of whole blood and tissues. RESULTS: The groups treated with enriched diets showed a significant reduction in body mass and lipogenesis in the epididymal and retroperitoneal adipose tissues and carcass when compared with the control group. However, lipogenesis in the liver showed an increase in Matrinxã group compared with the others groups. The levels of serum triglycerides in the treated groups with Amazonian fish were significantly lower than those of the control group. Moreover, total cholesterol concentration only decreased in the group Matrinxã. High Density Lipoprotein cholesterol levels increased significantly in the Mapará and Tambaqui compared with control group and Matrinxã group. The insulin and leptin levels increased significantly in all treatment groups. CONCLUSION: This study demonstrated that diets enriched with fatty fish from the Amazon basin changed the lipid metabolism by reducing serum triglycerides and increasing high density lipoprotein-cholesterol in rats fed with diets enriched with Mapará, Matrinxã, and Tambaqui.

Lipid metabolism disorder (LMD) is a public health issue. Spirulina platensis is a widely used natural weight-reducing agent and Spirulina platensis is a kind of protein source. In the present study, we aimed to evaluate the effect of Spirulina platensis protease hydrolyzate (SPPH) on the lipid metabolism and gut microbiota in high-fat diet (HFD)-fed rats. Our study showed that SPPH decreased the levels of triglyceride (TG), total cholesterol (TC), low-density-lipoprotein cholesterol (LDL-c), alanine transaminase (ALT), and aspartate transaminase (AST), but increased the level of high-density-lipoprotein cholesterol (HDL-c) in serum and liver. Moreover, SPPH had a hypolipidemic effect as indicated by the down-regulation of sterol regulatory element-binding transcription factor-1c (SREBP-1c), acetyl CoA carboxylase (ACC), SREBP-1c, and peroxisome proliferator-activated receptor-γ (PPARγ) and the up-regulation of adenosine 5’-monophosphate (AMP)-activated protein kinase (AMPK) and peroxisome proliferator-activated receptorα (PPARα) at the mRNA level in liver. SPPH treatment enriched the abundance of beneficial bacteria. In conclusion, our study showed that SPPH might be produce glucose metabolic benefits in rats with diet-induced LMD. The mechanisms underlying the beneficial effects of SPPH on the metabolism remain to be further investigated. Collectively, the above-mentioned findings illustrate that Spirulina platensis peptides have the potential to ameliorate lipid metabolic disorders, and our data provides evidence that SPPH might be used as an adjuvant therapy and functional food in obese and diabetic individuals.

The purpose of this study was to substantiate the possibility of correcting lipid metabolism changes at dark deprivation using linseed oil, melatonin, and their combination. Materials and methods. The experiment involved 130 white outbred male rats with a body weight of 170–220 g. The animals were divided into 5 groups: rats under standard fixed lighting conditions (12 hours light/12 hours dark); rats under modelled dark deprivation with round-the-clock lighting (24 hours light); rats under modelled dark deprivation with round-the-clock lighting (24 hours light) receiving intragastric injections of linseed oil, melatonin or their combination from day 1 of the experiment. Serum concentrations of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total phospholipids (TPL) and atherogenic index (AI) were determined. Results. Long-term dark deprivation led to dyslipoproteinemia, which consists in an increase in serum concentrations of TC by a factor of 1.33 (p = 0.0009), TG by a factor of 1.62 (p = 0.013), LDL-C by a factor of 1.2 (p = 0.026) and TPL by a factor of 1.15 (p = 0.0082). The severity of changes in TC, TG, LDL-C, HDL-C and TPL concentrations varied depending on the duration of the experiment. During the use of linseed oil, melatonin or their combination under dark deprivation, the severity of disorders caused by desynchronosis decreased and lipid metabolism in rat serum normalized, especially at the initial stages of the research. Conclusion. Changes in lipid metabolism due to desynchronosis in rats injected with the substances under study were significantly smaller compared with animals that did not receive them. The most pronounced effects of administering these substances were observed in the group of rats treated with linseed oil and melatonin at the same time.

Abstract Background Obesity is associated with insulin resistance, type2 diabetes, dyslipidemia and cardiovascular diseases. Apelin and chemerin are identified as adipokines and adipose tissue markers. Several adipose-derived peptides are known to influence food intake, including apelin, whose expression is regulated by insulin and chemerin. Oxidative stress thought to be involved in the development of complications associated with obesity. Objective To study the nature of correlation between serum and liver levels of apelin, chemerin and oxidative parameters in obese rats with and without antioxidant. Aiming to clarify the pathophysiology of obesity. Material and Methods Thirty adult male albino rats, divided into three equal groups. Group I (control), group II (obese) and group III (obese and Lepidium sativum (LS) as an antioxidants). At the end of the experiment, blood samples were collected for estimation of the serum levels of chemerin, apelin, fasting glucose, insulin, insulin resistance (IR), lipid profile, reduced glutathione (GSH) and malondialdehyde (MDA). In addition to tissue homogenous extracts of liver were taken for the levels of MDA, CAT, chemerin and apelin. Results After eight weeks, high fat diet group showed a significant increase in serum levels of apelin, chemerin, fasting glucose, insulin, IR, total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) & MDA and a significant decrease in high-density lipoprotein cholesterol (HDL-C) & GSH. HFD also caused a significant increase in tissue levels of MDA, CAT & chemerin and a significant decrease in apelin, compared to control group. While addition of LS to HFD caused a significant decrease in serum levels of apelin, chemerin, fasting glucose, insulin, IR, TC, TG, LDL-C & MDA and a significant increase in HDL-C & GSH. LS also caused a significant decrease in tissue levels of MDA, chemerin & insignificant decrease in CAT and a significant increase in apelin, compared to HFD group. Conclusion This study showed a significant positive correlation between liver & serum chemerin and between liver and serum MDA. On the other hand, it showed a significant negative correlation between liver and serum apelin and liver CAT and serum GSH
