Changes In Serum Lipid Profile Research Articles

Assessment of Lipid Profile and Clinical Manifestation of Obese Patients with Type 2 Diabetes

This case-control study involved 356 diabetic patients and 384 apparently healthy individuals, matched for age and sex, who attended the outpatient department at Al-Zahrawi Private Hospital in Mosul from January to December 2004. The study aimed to evaluate changes in serum lipid profile among type 2 diabetics in relation to body mass index (BMI) and determine the extent and pattern of dyslipidemia in obese diabetics. Fasting plasma glucose and serum lipid profile were compared between type 2 diabetics and control subjects based on BMI. Data analysis utilized chi-square, Z, ANOVA, and Duncan tests. Fasting plasma glucose levels were highest in obese diabetics, and the frequency of poorly controlled diabetics increased with higher BMI. There was a significant positive association between BMI and serum triglyceride (TG) (p < 0.01), total cholesterol (TC) (p < 0.001), LDL-C (p < 0.001), and VLDL-C (p < 0.01). Serum HDL-C levels significantly decreased (p < 0.01) with increasing BMI. The prevalence of dyslipidemia increased with higher BMI levels in both genders. In conclusion, several lipid abnormalities in type 2 diabetics underscore the importance of diabetic control, regular lipid profile monitoring, and obesity management.

The Antioxidant Dendrobium officinale Polysaccharide Modulates Host Metabolism and Gut Microbiota to Alleviate High-Fat Diet-Induced Atherosclerosis in ApoE-/- Mice.

The discovery of traditional plants' medicinal and nutritional properties has opened up new avenues for developing pharmaceutical and dietary strategies to prevent atherosclerosis. However, the effect of the antioxidant Dendrobium officinale polysaccharide (DOP) on atherosclerosis is still not elucidated. This study aims to investigate the inhibitory effect and the potential mechanism of DOP on high-fat diet-induced atherosclerosis in Apolipoprotein E knockout (ApoE-/-) mice. The identification of DOP was measured by high-performance gel permeation chromatography (HPLC) and Fourier transform infrared spectroscopy (FTIR). We used high-fat diet (HFD)-induced atherosclerosis in ApoE-/- mice as an animal model. In the DOP intervention stage, the DOP group was treated by gavage with 200 μL of 200 mg/kg DOP at regular times each day and continued for eight weeks. We detected changes in serum lipid profiles, inflammatory factors, anti-inflammatory factors, and antioxidant capacity to investigate the effect of the DOP on host metabolism. We also determined microbial composition using 16S rRNA gene sequencing to investigate whether the DOP could improve the structure of the gut microbiota in atherosclerotic mice. DOP effectively inhibited histopathological deterioration in atherosclerotic mice and significantly reduced serum lipid levels, inflammatory factors, and malondialdehyde (F/B) production. Additionally, the levels of anti-inflammatory factors and the activity of antioxidant enzymes, including superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX), were significantly increased after DOP intervention. Furthermore, we found that DOP restructures the gut microbiota composition by decreasing the Firmicutes/Bacteroidota (F/B) ratio. The Spearman's correlation analysis indicated that serum lipid profiles, antioxidant activity, and pro-/anti-inflammatory factors were associated with Firmicutes, Bacteroidota, Allobaculum, and Coriobacteriaceae_UCG-002. This study suggests that DOP has the potential to be developed as a food prebiotic for the treatment of atherosclerosis in the future.

Effects of ethanolic extract of <i>Aristolochia repens</i> on biochemical and histological changes in high-fat diet and streptozotocin-induced rats

The study evaluated the lipid profile, electrolytes and histological changes in diabetic Wistar rats treated with stem bark extract of Aristolochia repens. Type 2 diabetes was induced in rats with high-fat diet and low dose of streptozotocin (35 mg/kg body weight). A total of thirty-five Wistar rats were fed with high-fat diet for eight (8) weeks, while five (5) Wistar rats (Sham control) were fed with low-fat diet. Non-induced male Wistar rats were treated with distilled water (Sham control); while the induced male Wistar rats were treated with distilled water, metformin (100 mg/kg), 50, 100 and 200 mg/kg ethanolic extract of Aristolonchia repens stem bark for 28 days. The rats were sacrificed; liver, kidney and serum were collected and analyzed for serum glucose, lipid profile, electrolytes and histological changes. Treatment with ethanolic extract of Aristolonchia repens stem bark significantly reduced the body weight, glucose level, total cholesterol concentration, triglycerides, low-density lipoprotein concentration and atherogenic indices. Mild pathological alterations were observed in the liver and kidney of diabetic rats at dosage above 50 mg/kg. However, the extract reduced the blood glucose, lipids and improve the selected electrolyte balance. This study suggests that ethanolic extract of stem bark of A. repens possesses antihyperglycaemia and antilipidaemic potential and might not be safe at dosage above 50 mg/kg.

Bischofia javanica and Phaleria macrocarpa nano herbal combination on blood and liver-kidney biochemistry in Oral Squamous Cell Carcinoma-induced rats

This research explores a contemporary approach to managing Oral Squamous Cell Carcinoma (OSCC) by integrating nano-technology into herbal production, combining Bischofia javanica leaves and Phaleria macrocarpa fruits. Benzo[a]pyrene (BaP)-induced OSCC rats were treated with nano herbals from Bischofia javanica leaves, Phaleria macrocarpa fruits, a combination of both, and Vitamin C as a control. Blood and organ analyses were compared with negative and positive controls. BaP induction in OSCC revealed cell transformation into carcinoma, confirmed by Papanicolaou staining. OSCC induction also caused significant changes in Complete Blood Count (CBC) and serum lipid profile. Nano herbals from both plants showed potential in reducing hematological and lipid damage in OSCC, especially in white blood cells, red blood cells, hemoglobin, and platelets. Statistical analysis also indicated that the combination of nano herbals was more effective in reducing (Low-Density Lipoprotein) LDL and total cholesterol levels than uncombined use while increasing (High-Density Lipoprotein) HDL levels comparable to Vitamin C. Liver and kidney functions were also significantly affected by OSCC, with nano herbals showing potential in normalizing albumin levels and positively impacting liver enzymes. In conclusion, both individually and in combination, nano herbals from Bischofia javanica leaves, and Phaleria macrocarpa fruits have the potential to be a promising treatment strategy for OSCC.

Metabolomic Alterations in Methotrexate Treatment of Moderate-to-Severe Psoriasis.

BACKGROUND Aberrant lipid metabolism alterations in skin tissue, blood, or urine have been implicated in psoriasis. Here, we examined lipid metabolites related to psoriasis and their association with the age of disease onset. MATERIAL AND METHODS Differences in lipid metabolites before and after methotrexate (MTX) treatment were evaluated. The discovery cohort and validation cohort consisted of 50 and 46 patients, respectively, with moderate-to-severe psoriasis. After MTX treatment, the patients were divided into response (Psoriasis Area and Severity Index [PASI] 75 and above) and non-response (PASI below 75) groups, blood was collected for serum metabolomics, and multivariate statistical analysis was performed. RESULTS We detected 1546 lipid metabolites. The proportion of the top 3 metabolites was as follows: triglycerides (TG, 34.8%), phospholipids (PE, 14.5%), phosphatidylcholine (PC, 12.4%); diglycerides (DG) (16: 1/18: 1), and DG (18: 1/18: 1) showed strong positive correlations with onset age. There were marked changes in TG (16: 0/18: 0/20: 0), TG (18: 0/18: 0/22: 0), TG (14: 0/18: 0/22: 0), TG (14: 0/20: 0/20: 0), lysophosphatidylcholine (LPC) (16: 0/0: 0), LPC (18: 0/0: 0), LPC (14: 0/0: 0), and LPC (18: 1/0: 0) levels before and after 12 weeks of MTX treatment. The glycerophospholipid metabolic pathway was implicated in psoriasis development. Of the 96 recruited patients, 35% were MTX responders and 65% non-responders. PE (34: 4) and PE (38: 1) levels were significantly different between the groups. Obvious differences in lipid metabolism were found between early-onset (<40 years) and late-onset (≥40 years) psoriasis. Significant changes in serum lipid profile before and after MTX treatment were observed. CONCLUSIONS The specific lipid level changes in responders may serve as an index for MTX treatment efficacy evaluation.

The clinical importance and correlations of post-partum changes in the clinical findings, reproductive cyclicity, serum-milk oxidant/antioxidant parameters as a stress indicator in female dromedary camel (Camelus dromedarius) and their effect on milk palatability

Dramatic metabolic changes during pregnancy and post-partum period resulted in alteration of the biochemical parameters in dromedary she-camels. The current study focused on assessment of stress indicators in post-partum dromedary she-camels on days 14, 28 and 42 post-calving through monitoring the clinical findings, serum steroid hormones, serum or milk oxidant/antioxidant indicators, and milk somatic cell count (SCC) status with reference to serum lipid profile changes. The study also stated several correlations between reproductive cyclicity parameters, stress biomarkers and serum-milk oxidant/antioxidant indicators. The study was conducted on clinically healthy recently calved she-camels (n = 25). They were subjected to clinical and laboratory assays including lipid profiles, serum steroid hormones [Progesterone (P4) and estradiol (E2)], serum or milk oxidant/antioxidant biomarkers [Malondialdehyde (MDA), reduced glutathione (GSH) and cortisol], and milk SCC on days 14, 21 and 28 post-calving. The study concluded the influence of stress as a result of lactation in post-partum period in recently calved she-camels and its relationship with reproductive cyclicity as well as changes in serum steroids, lipid profiles, serum-milk oxidant/antioxidants parameters, and milk SCC that was reflected through significant elevations in serum levels of P4, E2, cortisol, MDA and glucose, and milk values of MDA, cortisol and SCC as well as significant drop in serum levels of GSH, TPs, albumins and globulins on day 14 post-calving comparing with their values particularly on day 42. The study stated variable correlation relationships between reproductive cyclicity parameters, lipid profiles, serum-milk oxidant/antioxidants parameters and milk SCC.

Comparative evaluation of the serum biochemical and lipid profile changes in spayed male and female rats

Background and aims: This study investigated the effects of gonadal removal in male and female rats on changes in serum biochemical parameters. Methods: Twenty-eight adult male and female rats were divided into four groups of 7 animals for a period of 9 weeks. The first and second groups of intact male and female rats, as well as the third and fourth groups of male and female rats, were gonadectomized, respectively. At the end of the ninth week of the study, the rats were anesthetized with chloroform, and the amount of glucose, some lipid parameters in serum, and the activity of a number of serum enzymes were measured after taking blood from the heart. Results: Alanine aminotransferase, and alkaline phosphatase (ALP) levels were higher in intact male rats than in intact female rats, respectively (P=0.03, P=0.015). The amounts of glucose and cholesterol of low-density lipoprotein (LDL) in intact female rats were higher than in the ovariectomized rats, respectively (P=0.07, P=0.039, P=0.03). The amount of lactate dehydrogenase (LDH) in spayed female rats demonstrated a significant increase compared to other groups (P=0.001). However, there was a significant decrease in calcium levels in gonadectomized rat groups in comparison to intact female rats (P=0.02). Finally, a significant increase was found in phosphorous levels in the intact male rats group compared to other groups (P=0.002). Conclusion: Decreased sex hormones in gonadectomized rats compared with intact rats could lead to increased serum levels of LDH, ALP, and LDL cholesterol that may result in the development of metabolic and atherogenesis syndromes and acute liver failure.

Exploring Serum Lipid Profile Changes in Patients During Laparoscopic Choecystectomy

Background: For quite some time, cholecystectomy has been perceived as a safe surgical procedure, often with limited attention given to potential secondary effects. It's worth noting that the gallbladder plays a significant role as a regulatory component in coordination with vital metabolic pathways responsible for maintaining equilibrium in the body. When the gallbladder is removed, bile from the liver flows directly into the upper portion of the intestine. Therefore, this study aims to evaluate the impact of laparoscopic cholecystectomy on the serum lipid profile of patients. Material and methods: A total of 60 patients diagnosed with gallstones were enrolled in this study. Preoperative blood samples were collected from all patients under sterile conditions, two hours prior to their scheduled surgery, to evaluate their lipid profile. Results: The preoperative mean Total Cholesterol (TC) levels were measured at 160.5 mg%, while postoperatively, they showed a slight decrease to 150.8 mg%. Similarly, the mean High-Density Lipoprotein Cholesterol (HDL-C) levels before surgery were 42.1 mg%, and they decreased to 40.8 mg% after the procedure. In contrast, the mean Triglyceride (TG) levels saw an increase from 180.8 mg% preoperatively to 200.8 mg% postoperatively. Notably, the comparison of mean TC and TG levels before and after the surgery yielded significant results, indicating changes in these lipid parameters following laparoscopic cholecystectomy. Conclusion: Patients undergoing laparoscopic cholecystectomy experience noteworthy changes in their serum lipid profile.

The protective role of l-carnitine on oxidative stress, neurotransmitter perturbations, astrogliosis, and apoptosis induced by thiamethoxam in the brains of male rats

Synthetic organic insecticides such as pyrethroids, organophosphates, neonicotinoids, and others have the potential to disrupt ecosystems and are often toxic to humans. Thiamethoxam (TMX), a neonicotinoid insecticide , is a widely used insecticide with neurotoxic potential. l-Carnitine (LC) is regarded as the “gatekeeper” in charge of allowing long-chain fatty acids into cell mitochondria. LC is an endogenous chemical that is renowned for its prospective biological activity in addition to its role in energy metabolism. This study investigated the protective effects of LC against TMX-induced neurotoxicity in male Wistar rats. For 28 days, animals were divided into four groups and treated daily with either LC (300 mg/kg), TMX (100 mg/kg), or both at the aforementioned doses. Our results revealed marked serum lipid profile and electrolyte changes, declines in brain antioxidants and neurotransmitters (acetylcholine, dopamine, and serotonin levels) with elevations in thiobarbituric acid reactive substances and proinflammatory cytokine levels, as well as acetylcholinesterase and monoamine oxidase brain activity in TMX-treated rats. TMX also increased the expression of caspase-3 and glial fibrillary acidic protein. In contrast, pretreatment with LC attenuated TMX-induced brain injury by suppressing oxidative stress and proinflammatory cytokines and modulating neurotransmitter levels. It also ameliorated the expression of apoptotic and astrogliosis markers. It could be concluded that LC has antioxidant, anti-inflammatory, anti-astrogliosis, and anti-apoptotic potential against TMX neurotoxicity.Graphical abstract

Effect of pregnancy and lactation on the serum lipid profiles: cholesterol and triacylglycerol ratios of apparently healthy large white sows

This study evaluated the effects of pregnancy and lactation on the serum lipid profiles of large white (LW) sows. Twenty (20) sexually matured LW sows and three (3) LW boars, of mean weight 45.38±1.29 kg, aged between 8 and 10 months were used for this study. The sows were randomly assigned to five groups (A to E) of four sows per group in a completely randomized design (CRD). Group A: Non pregnant (control), Group B: Early gestation (38 days), Group C: Mid gestation (78 days), Group D: Late gestation (112 days) and Group E: Post gestation (14 days postpartum). Blood samples were collected during five stages of gestation. The mean total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) concentrations of group A (non-mated or control group) were significantly (p &lt; 0.05) higher than groups B and C. The mean total cholesterol:high density lipoprotein cholesterol (TC/HDL-C) and low density lipoprotein cholesterol:high density lipoprotein cholesterol (LDL-C/HDL-C) ratios of the postpartum sows were significantly (p &lt; 0.05) lower than group C. There were however no significant (p &gt; 0.05) variations in the mean triacylglycerol (TAG), low density lipoprotein cholesterol (LDL-C), triacylglycerol:high density lipoprotein cholesterol (TAG/HDL-C) ratio and very low density lipoprotein cholesterol (VLDL-C) concentrations among all the groups. This present study has presented preliminary information on the changes of serum lipid profiles, cholesterol and triacylglycerol ratios during gestation in LW sows that can be sought by the scientific community

A bifunctional anti-PCSK9 scFv/Exendin-4 fusion protein exhibits enhanced lipid-lowering effects via targeting multiple signaling pathways in HFD-fed mice

Fusion protein which encompasses more than one functional component, has become one of the most important representatives of macromolecular drugs for disease treatment since that monotherapy itself might not be effective enough to eradicate the disease. In this study, we sought to construct a bifunctional antibody fusion protein by fusing anti-PCSK9 scFv with Exendin-4 for simultaneously lowering both LDL-C and TG. Firstly, three Ex4-anti-PCSK9 scFv fusion proteins were constructed by genetically connecting the C-terminal of Exendin-4 to the N-terminal of anti-PCSK9 scFv through various flexible linker peptides (G4S)n (n = 2, 3, 4). After soluble expression in E. coli, the most potent Ex4-(G4S)4-anti-PCSK9 scFv fusion protein was selected based on in vitro activity assays. Then, we investigated the in vivo therapeutic effects of Ex4-(G4S)4-anti-PCSK9 scFv on the serum lipid profile and bodyweight changes as well as underlying molecular mechanism in HFD-fed C57BL/6 mice. The data showed that Ex4-(G4S)4-anti-PCSK9 scFv exhibits enhanced effects of lowering both LDL-C and TG in serum, reducing food intake and body weight via blocking PCSK9/LDLR, activating AMPK/SREBP-1 pathways, and up-regulating sirt6. Conclusively, Ex4-(G4S)4-anti-PCSK9 has the potential to serve as a promising therapeutic agent for effectively treating dyslipidemia with high levels of both LDL-C and TG.

Increased Carotid Intima-media Thickness and Its Association with Carbohydrate Metabolism and Adipocytokines in Children Treated with Recombinant Growth Hormone.

Reports on the association between growth hormone therapy and cardiovascular risk factors in children are limited. This study aimed to evaluate carotid intima-media thickness (cIMT) in children treated with recombinant human growth hormone (rhGH) and assess the effects of rhGH therapy and changes in serum carbohydrate metabolism, lipid profile and adipocytokines on cIMT. Seventy-one isolated idiopathic GH deficiency (GHD) children and 44 age- and sex-matched, healthy controls were enrolled in this study. The study group was divided into two subgroups according to insulin resistance (IR) on oral glucose tolerance tests. Insulin secretion (HOMA B, total insulin) and sensitivity (HOMA-IR, QUICKI, Matsuda) indices were calculated. cIMT was measured and the standard deviation scores (SDS) were calculated. Associations between cIMT-SDS and insulin secretion and sensitivity indices, serum lipid levels, adipocytokines (leptin, resistin, ghrelin), and the other rhGH treatment-related factors were evaluated. The cIMT-SDS was increased in GHD children treated with rhGH compared to controls (0.02 (2.27) vs -1.01 (1.63), p=0.003). cIMT-SDS did not differ between children on rhGH treatment with or without IR. High cIMT-SDS was significantly associated with higher serum ghrelin level and lower serum high density lipoprotein level (ß=0.491, p=0.001 and ß= -0.027, p=0.017), but not with BMI-SDS, blood pressure, insulin secretion and sensitivity indices, or dose and duration of rhGH therapy. Our findings showed that GHD children treated with rhGH have increased cIMT. Alterations in carbohydrate metabolism were not associated with cIMT in children treated with rhGH. GH therapy per se appears to be associated with this increased cIMT but causality should be elucidated in further studies. cIMT also appears to be associated with higher ghrelin and lower HDL levels.

Antioxidant and antidiabetic activities of a polyphenol rich extract obtained from Abelmoschus esculentus (okra) seeds using optimized conditions in microwave-assisted extraction (MAE).

Functional foods have gained popularity in recent decades. They are exploited for their bioactive compounds like polyphenols, which are highly demanded in cosmetic, pharmaceutical and nutraceutical industries. However, extractive techniques and conditions used up to recently are almost obsolete and must be optimized for higher efficiency. The current study aimed to evaluate the antidiabetic potential of an optimized extract of Abelmoschus esculentus (okra) seeds. The optimal conditions for extracting polyphenolic compounds from okra seeds were determined using Microwave Assisted Extraction (MAE). A Face Center Composite Design (FCCD) was used for optimization. Solvent/dry matter ratio, wavelength and time were considered while the response studied was the polyphenolic content. The extract obtained at optimal conditions was characterized using Thin Layer Chromatography (TLC) and Fourier Transform Infra-Red (FTIR) spectroscopy, then tested for its antioxidant, alpha amylase inhibitory and antidiabetic activities. Response Surface Methodology (RSM) permitted the determination of the optimal conditions for phenols extraction as: microwave power 330 W, with a solvent ratio of 97.04/1 mL/g for 9.5 min of extraction time. The optimized extract showed a phenolic content up to 86.37 ± 1.13 mg GAE/g containing quercetin and catechin as revealed by the TLC. Functional groups characteristic of polyphenols were identified on FTIR spectra, and the extract exhibited good in vitro antioxidant capacities with DPPH (2, 2-diphenyl-1-picrylhydrazyl) radical scavenging capacity and FRAP (Ferric Reducing Antioxidant Power Assay). An IC50 of 3.99 ± 0.15 μg/mL was obtained with the DPPH scavenging test. Alpha amylase inhibitory assay revealed that the optimized okra extract behaved as a non-competitive inhibitor of porcine pancreatic amylase with an IC50 of 484.17 ± 2.33 μg/mL. Antidiabetic activity of the extract was observed in streptozotocin-induced diabetic males Wistar rats, as shown by the fasting blood glucose levels, food intake, changes in body weight and serum lipid profile among others.

Changes in serum lipid profiles of weaner rabbits fed diets fortified with processed Garcinia kola seed

Background: A fifty-six (56) day experiment was conducted at the small animal experimental unit of Federal College of Wildlife Management, New-Bussa, Niger State to determine the effect of fortifying the feed of weaned rabbits with graded levels of Garcinia kola (G. kola). Methods: Forty unsexed New-Zealand white rabbits weighing between 0.90-0.92kg used for this experiment were randomly distributed into five dietary treatments tagged T1, T2, T3, T4 and T5 using a Completely Randomized Design (CRD). The experimental rabbits were fed with Iso-Caloric and Iso-Nitrogenous diets that are rich in lipids with a very high metabolizable energy (M/E). Rabbits in T1which served as the control were fed plain diets not fortified with G. kola. Rabbits in treatments 2 to 5 were fed diets fortified with graded level of processed G. kola seeds at 5g/100g, 10g/100g, 15g/100g and 20g/100g respectively and the animals were fed at 10% of their body biomass by monitoring the weight on weekly basis. Results: Data obtained from this study revealed that feeding of weaner rabbits with feed fortified with powdered G. kola seed produced a significant (p&lt;0.05) dose-dependent serum-lipid lowering effects as compared to the control group, this may be mediated by some of the phytochemical and nutritional constituents of G. kola. The phytochemical analysis revealed that values of Tannin Flavonoids, Saponin and Alkaloids ranges from 5.94 ± 0.58%, 1.57 ± 0.37%, 3.46 ± 0.365% and 6.58 ± 0.38% respectively while the results of the Proximate analysis revealed that G. kola seed contained 8.51 ± 0.045% Moisture, 2.39 ± 0.420% Protein, 4.65 ± 0.365% Ash and 75.91 ± 2.265%NFE. Conclusion: This research work has revealed that G. kola seed has a hypolipidemic effect when consumed and that consumption of G. kola seed may help in the reduction of the incidence of cardiovascular.

Changes of serum lipid profiles and the correlation analysis in clinic-pathological features of pancreatic cancer patients

Objective: To examine the characteristics of blood lipid profile and the correlation with clinic-pathological features of pancreatic cancer patients. Methods: The clinical and pathological data of 265 pancreatic cancer patients who received radical surgical treatment at Department of General Surgery,Qilu Hospital,Shandong University from January 2013 to September 2020 were collected and analyzed retrospectively. Among the 265 pancreatic cancer patients,there were 170 males and 95 females,with age of (61.0±9.6)years(range:28 to 86 years). General information,lipid indicators and clinic-pathological information were collected from electronic medical record system,and follow-up information gained by telephone. According to level of serum lipid in pancreatic cancer patients,265 patients were divided into dyslipidemia group(n=115) and normal lipid group(n=150). Pearson χ2,Student's t tests, variance analysis or univariate Logistic regression was used to analyze the correlation between dyslipidemia and clinico-pathological characteristics of pancreatic cancer,respectively. Kaplan-Meier survival curve was used to assessed the influence of dyslipidemia on prognosis of pancreatic cancer patients. Results: In 265 pancreatic cancer patients,115(43.4%)of them had dyslipidemias,and the most common form was increase of triglyceride(TG)(72.2%). In pancreatic cancer with dyslipidemias group,patients with body mass index ≥25 kg/m2 had higher proportion than normal lipid group(36.1%(26/72) vs. 21.2%(21/99),χ²=4.643,P=0.031); The proportion of carcinoma located at head of pancreas(83.5%(96/115) vs. 40.7%(61/150),χ²=49.412,P<0.01), staging of T1/T2(79.1%(91/115) vs. 60.7%(91/150),χ²=10.316,P<0.01) and lymphatic metastasis(36.5%(42/115) vs. 22.7%(34/150),χ²=6.007,P<0.01) were higher. In patients of pancreatic cancer, dyslipidemias were closely associated with tumor location(OR=10.529,P<0.01)and body mass index(OR=3.671,P=0.008). Serum lipid profile results showed that TG,total cholesterol and high-density lipoprotein(HDL) disorders were associated with tumor location(P<0.05). TG disorder had association with body mass index(P<0.05), and HDL disorder had association with tumor stage(P<0.05). Moreover, the result of survival analysis showed that dyslipidemia was not a factor to impact the prognosis of pancreatic cancer patients underwent surgery(P>0.05). Conclusions: In pancreatic cancer patients,TG disorder was the most common type of dyslipidemia. Dyslipidemia has closely association with clinicopathologic features,including tumor location,body mass index,tumor stage. However,dyslipidemia had little effect on prognosis of pancreatic cancer patients.

A STUDY OF LIPID PROFILE IN ANAEMIA

Objectives:Both anemia and dyslipidemia are widely prevalent public health problems, especiallyin the Indian population. Associationof anemia and dyslipidemias were reported in some individual experimental animals. The study was planned to find thechanges in serum lipid profile in adult Indian patients with anemia. Material and methods:100 cases of anemia (hemoglobin &lt;13 g% in men and &lt;12 g% in women), and 100 age and sex matched healthy controls, in the age group 18-40 years were investigated for any possible changes in serum lipid profile i.e.,triglycerides, total cholesterol, high density lipoprotein cholesterol, very low density lipoprotein cholesterol. Results:The mean cholesterol in patients with anemia was 122.47 ± 29.32 mg/dl, whereas in controls group was 160.43 ± 38.91 mg/dl. The mean serum triglyceride level in patients with anemia was 89.41 ± 33.1532 mg/dl and in control group was 111.45 ± 40.6632 mg/dl. Mean high-density lipoprotein levels were 36.13 ± 12.8132 mg/dl in anemic group and 45 ± 13.032 mg/dl in control group, whereas low-density lipoprotein (LDL) cholesterol level was 70.12 ± 21.64 mg/dl in the anemic group and 100.45 ± 30.8032 mg/dl in control group. VLDL levels were higher in control group (21.96 ± 8.132 mg/dl) compared to the anemic group (18.34 ± 7.6432 mg/dl). Conclusion: Lipoproteins levels were significantly abnormal in anemic as compared to non-anemic subjects.

Standard-Dose Atorvastatin Treatment in Patients With Symptomatic Middle Cerebral Artery Atherosclerotic Stenosis: A Vessel Wall Magnetic Resonance Imaging Study.

Background and Purpose: Ischemic stroke can be caused by atherosclerotic lesions of the middle cerebral artery (MCA). Some studies have described the effects of statin treatment on carotid artery plaques, but little is known about the effects of statin treatment on MCA plaques. The purpose of this study was to validate the efficacy of standard-dose atorvastatin (20 mg/day) in patients with symptomatic MCA atherosclerotic stenosis (SMAS) in northern China.Materials and Methods: This study is a prospective, single-arm, single-center, 12-month follow-up observational study monitoring imaging, and clinical outcomes of standard-dose atorvastatin treatment among patients with SMAS. The primary outcomes were changes in vessel wall magnetic resonance imaging (VWMRI) and serum lipid profiles before and after (1, 3, 6, and 12 months) statin treatment.Results: A total of 46 patients were recruited for this study, and 24 patients completed the follow-up. During the follow-up period, serum non-high-density lipoprotein cholesterol concentrations gradually decreased in the patients. Fourteen patients (54.33%) had a reversal of MCA plaques and 10 patients (41.67%) had no significant progression of MCA plaques and remained stable at the follow-up endpoint. At the 12 months follow-up time-point, the treatment did not reverse vascular remodeling or change the shape and distribution of plaques. Altered serum low-density lipoprotein cholesterol (LDL-C) concentrations in patients were strongly associated with plaque reversal.Conclusion: Vessel wall magnetic resonance imaging could accurately characterize changes in MCA plaques after lipid-lowering therapy. Standard-dose atorvastatin treatment could stabilize and reverse plaques in northern Chinese patients with SMAS.

Changes in Serum Lipid Profiles among Canine Patients Suffering from Chronic Hepatitis

Hyperlipidemia is a risk factor for nonalcoholic fatty liver disease (NAFLD) in humans. However, the association between serum lipids and canine chronic hepatitis remains unknown. In this study, serum lipids, hepatic profiles, and hepatic ultrasound scores of healthy dogs and dogs with chronic hepatitis were evaluated. Serum triglyceride and cholesterol concentrations were significantly higher (p < 0.01) in dogs with chronic hepatitis. There were 62.2% of dogs with chronic hepatitis accompanied by hypertriglyceridemia, hypercholesterolemia, or both. Positive correlations were observed between serum ALT and cholesterol (r = 0.8287, p < 0.01), serum ALP and cholesterol (r = 0.8436, p < 0.01), serum GGT and cholesterol (r = 0.5640, p < 0.01), serum bile acid and cholesterol (r = 0.3310, p < 0.01) and serum ALP and triglycerides (r = 0.2582, p < 0.05). No significant differences were found between ultrasound scores of diseased dogs with and without hypertriglyceridemia and diseased dogs with and without hypercholesterolemia. Canine chronic hepatitis is associated with hyperlipidemia. A significant positive association was identified between hyperlipidemia, especially hypercholesterolemia, liver enzymes, and bile acid concentration in dogs suffering from chronic hepatitis. The underlying mechanisms connecting hyperlipidemia and canine chronic hepatitis remain elusive.

Predictive value of a reduction in the level of high-density lipoprotein-cholesterol in patients with non-small-cell lung cancer undergoing radical resection and adjuvant chemotherapy: a retrospective observational study

BackgroundCancer patients often exhibit chemotherapy-associated changes in serum lipid profiles, however, their prognostic value before and after adjuvant chemotherapy on survival among non-small-cell lung cancer (NSCLC) patients is unknown.MethodsNSCLC patients undergoing radical resection and subsequent adjuvant chemotherapy from 2013 to 2017 at Sun Yat-sen University Cancer Center were retrospectively reviewed. Fasted serum lipid levels were measured before and after chemotherapy. The optimal lipid cut-off values at baseline and fluctuation were determined using X-tile™. The fluctuations in serum lipid levels and disease-free survival (DFS) were assessed.ResultsSerum cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), triglyceride, apolipoprotein (Apo) A-I, and ApoB all significantly increased after adjuvant chemotherapy. X-tile determined 1.52 mmol/L of HDL-C and 0.74 g/L of ApoB as the optimal cut-off values before chemotherapy. Patients with HDL-C ≥ 1.52 mmol/L (median DFS: not reached vs. 26.30 months, P = 0.0005) and a decreased HDL-C level after adjuvant chemotherapy (median DFS: 80.43 vs. 26.12 months, P = 0.0204) had a longer DFS. An HDL-C level that increased by ≥ 0.32 mmol/L after chemotherapy indicated a worse DFS. A high baseline ApoB level were associated with a superior DFS. In the univariate analysis and the multivariate Cox analyses, a high baseline HDL-C level and a HDL-C reduction after adjuvant chemotherapy were independent indicators for superior DFS. High baseline HDL-C was related to N0-1 stage (χ2 = 6.413, P = 0.011), and HDL-C fluctuation was significantly correlated with specific chemotherapy regimens (χ2 = 5.002, P = 0.025).ConclusionsAdjuvant chemotherapy increased various lipid levels in resected NSCLC patients. A higher HDL-C level before chemotherapy and a reduced HDL-C level after adjuvant chemotherapy were independent predictors of longer DFS in patients with curable NSCLC.
