Dyslipidemia and oxidative modifications of lipid are frequently associated in patients with chronic kidney diseases (CKD) and considered the most important risk factors for cardiovascular events. Melatonin is a well-known potent antioxidant and has beneficial effect on lipid metabolism. the study was designed to evaluate if Melatonin could improve lipid profile and ameliorates lipid peroxidation. This single blind placebo controlled clinical study carried out on 41 patients with CKD who were randomized into two groups, control groups (n=20) those who received placebo cap and melatonin group those who received 5mg melatonin (n=21). Lipid profile [total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL-C), low-density lipoprotein (LDL-C)] and parameters of lipid peroxidation [oxidized LDL (oxLDL) and malondialdehyde (MDA) were measured before and after 12 weeks of the treatment. After 12 weeks of treatment, melatonin significantly increased HDL-C and decreased LDL-C compared to the initial value. The elevation in HDL-C and reduction in LDL-C were significantly different from that in placebo group. Also, both oxLDL and MDA levels significantly lowered by melatonin compared to the baseline and to the placebo group. Collectively, the results of our study showed that melatonin has advantageous effect on lipid profile and inhibit lipid peroxidation in patients with CKD.

Abstract Objective: The aim of this study is to investigate the effect of one-rod levonorgestrel implant on the blood chemistry profile which include random blood glucose (RBG), hemoglobin (Hb), alanine transferase (ALT), aspartate transferase (AST), and lipid profile such as total cholesterol, High-density lipoprotein (HDL), Low-density lipoprotein (LDL), and triglycerideMethods: This prospective cohort study was conducted at Raden Saleh Clinic, Jakarta from 2010 to 2012. The implants were inserted subdermally in 30 patients. The subjects were evaluated for 6 months and the blood chemistry profile was followed up to 2 years. Bivariate analysis using t-test or Wilcoxon signed rank test was performed for all variables. The p <0.05 was considered as a significant value. Results: The level of Hb, RBG, AST, and lipid profile was different significantly before and after 6-months one-rod implant insertion (p<0.05). However, in 24 months, all of parameters were still on normal limit and not different clinically. Conclusion: One-rod levonorgestrel implant insertion shows minimal effect to all blood chemistry profiles.

Peroxidation of low-density lipoprotein (LDL) lipid is generally thought to represent the initial step in a series of modification reactions that ultimately transform the protein moiety of the lipoprotein into a form recognized by receptors different from those that bind native LDL. Uptake of LDL via these alternative receptors can lead to the formation of lipid-laden cells, which are typical for the early stages of atherogenesis. We have studied the oxidative modification of LDL by hypochlorite (-OCl), a powerful oxidant produced from H2O2 and chloride via the action of myeloperoxidase which is released from activated neutrophils and monocytes. Exposure of LDL to reagent or enzymically generated -OCl at 4 or 37 degrees C resulted in immediate and preferential oxidation of amino acid residues of apolipoprotein B-100, the single protein associated with LDL. Lysine residues quantitatively represented the major target and, like tryptophan, were oxidized to approximately the same extent with reagent or enzymically generated -OCl. In contrast, LDL lipid oxidation was less favoured than protein oxidation, as judged by the amounts of lipid hydroperoxides, chlorohydrins, cholesterol or fatty acid oxidation products formed. Treatment with -OCl caused aggregation of LDL, as shown by an increased turbidity of the oxidized LDL solution and elution from a size-exclusion h.p.l.c. column of high-molecular-mass LDL complexes. Chemical modification of lysine residues before oxidation with -OCl prevented aggregation, while it enhanced the extent of lipid peroxidation. Treatment of LDL with -OCl also caused the formation of carbonyl groups and release of ammonia; both these modifications were inhibited by lysine-residue modification before oxidation. These results demonstrate that aggregation reactions are dependent on initial lysine oxidation by -OCl, followed by deamination and carbonyl formation, but do not involve lipid (per)oxidation. We propose that the observed -OCl-mediated aggregation of LDL is caused, at least in part, by cross-linking of apoproteins by Schiff-base formation independently of lipid peroxidation.

Abstract Purpose: Lipid-lowering therapy is guided by Low-density-lipoprotein cholesterol (LDL-c), although the CVD risk could be better reflected by other lipid parameters. This study aimed the evaluation of a comprehensive lipid profile in patients with type 2 diabetes mellitus (T2DM) and comparation of those achieving and not achieving LDL-c control in respect to other non-conventional lipid parameters. Methods: We characterized a comprehensive lipid profile in 96 T2DM patients. ESC/EAS 2016 and 2019 Guidelines for the Management of Dyslipidemias were used to define LDL-c targets. Atherogenic lipoprotein profile was compared in patients with LDL-c within and above the target. Results: Only 28.1% and 16.7% of patients had mean LDL-c levels within the 2016 and 2019 guidelines, respectively. In patients with LDL-c within target by the 2016 guidelines, 22%, 25% and 44% presented levels above the recommended range for non-HDL-c, ApoB and oxidized LDL-c, respectively, whereas accordingly to the 2019 guidelines, 50%, 39% and 44% had elevated levels of -HDL-c, ApoB and oxidized LDL-c, respectively. There was a significant strong association of LDL-c and non-HDL-c (r=0.850), ApoB (r=0.656) and oxidized LDL-c (r=0.508). Similarly, non-HDL-c was significantly strongly correlated with ApoB (r=0.808) and oxidized LDL-c (r=0.588). Conclusions: These findings emphasize the limitations of a sole LDL-c measurement for CV risk assessment. Targeting only LDL-c could result in missed opportunities for CV risk reduction in T2DM individuals. Our data suggest that non-HDL-c, ApoB and oxidized LDL-c could be considered as part of these patients’ evaluation allowing a more accurate estimation of CV risk and treatment among these high-risk patients.

Introduction: Dyslipidemia is one of the most common problems in hemodialysis patients and healthcare system. Some studies have suggested the use of carnitine in the treatment of dyslipidemia in hemodialysis patients. This study was carried out aiming to evaluate the effect of atorvastatin and carnitine combination versus atorvastatin alone on the lipid profile of hemodialyzed patients. Methods: In this clinical trial, 50 hemodialysis patients referred to the educational centres of Tabriz University of Medical Sciences, Tabriz, Iran, for haemodialysis were enrolled. Patients were randomly assigned into two groups. In the first group, patients were treated with carnitine (1000 mg three times daily) and atorvastatin (10-80 mg/day based on the baseline lipid profile of the patients) and in the second group, the patients were treated with atorvastatin alone for six months. The levels of triglyceride (TG), cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and haemoglobin before and after intervention were compared. The side effects of carnitine administration were also evaluated. Results: Results showed that TG, cholesterol, and LDL levels were significantly lower in the carnitine group compared to those in the other group at the end of study (P < 0.050). In addition, HDL and haemoglobin levels were significantly higher in the carnitine group in comparison to the other group (P < 0.050). No major side effects of carnitine were observed among the patients. Conclusion: The use of carnitine plus atorvastatin combination is an effective and safe method in the treatment of dyslipidemia in patients undergoing hemodialysis without imposing significant side effects.

The consequences of maternal experience of Domestic Violence (DV) on their children’s cardio-metabolic risk factors are unclear. We aimed to assess if maternal exposure to any or a specific form of DV (i.e., physical, sexual, emotional and controlling behaviors) before and after childbirth was associated with their children’s lipid biomarkers at the age of 10 years. A current observational sub-study of a larger MINIMat trial included a cohort of 1167 mothers and their children. The conflict tactic scale was used to record women’s experience of lifetime DV before and after childbirth at week 30 of pregnancy and at a 10-year follow up, respectively. Five ml of fasting blood sample was collected from the children to evaluate their lipid profile. Children of women who experienced any DV before childbirth had lower Apo A (βadj −0.04; 95% CI: −0.08, −0.01). Women who experienced physical DV both before and after childbirth had children with higher triglycerides (βadj 0.07; 95% CI: 0.01, 0.14). Children whose mother experienced sexual DV before birth had lower Apo A (βadj −0.05; 95% CI: −0.08, −0.01) and High Density Lipoprotein (HDL) (βadj −0.05; 95% CI: −0.10, −0.01) as well as higher Low Density Lipoprotein (LDL) (βadj 0.17; 95% CI: 0.05, 0.29) and LDL/HDL (β 0.24; 95% CI: 0.11, 0.38). However, levels of LDL (βadj −0.17; 95% CI: −0.28, −0.06), LDL/HDL (βadj −0.12; 95% CI: −0.25, −0.00) and cholesterol (βadj −0.13; 95% CI: −0.25, −0.02) were lower among the children of mothers who experienced controlling behavior after childbirth. Results from the current study suggest that maternal experience of physical or sexual DV might negatively affect their children’s lipid profile at the age of 10 years.

This study aims to know and determine the lipid profile in patients with hyperlipidemia who consumed Generic Simvastatin comparedwith its patent product contained in the Formularium at Sanglah Hospital. The observations made, were the measurement of the totalcholesterol and low-density lipoprotein (LDL) before and after the drug administration. A total of 30 subjects who met the inclusioncriteria, were divided into two (2) groups, each group consist of 15 persons, the first group was given 20 mg generic Simvastatin(1 tablet daily) for 15 days and Group II given 20 mg patent Simvastatin (1 tablet daily) for 15 day. After 15 days, their blood sampleswere taken and examined for total cholesterol and LDL. Once the data were collected, statistical analysis was done by using the normalitytest, homogeneity and t. Statistical analysis using p-value less than or equal to 0.05 was the limit of significance. The statistical analysisshowed that the data was normally distributed and homogeneous (p≥0.05). The T-test showed that there were significant differencesin the levels of total cholesterol and LDL serum samples before and after the administration of generic simvastatin and patents the(sig.=0.000). However, there was no significant difference in decreased levels of totall cholesterol samples between the generic Simvastatinand patent (sig=0.365 with α=0.05 level). Besides this, there was also no significant difference in the decreased levels of LDL betweengeneric Simvastatin and the patent one (sig=0.372 with α=0.05 level).

To evaluate the effect of Ramadan fast on serum lipid profile status of men, the study was carried out in the National Mushroom Development and Extension Centre, Sobhanbag, Savar Dhaka in association with the Department of Pharmacy and Department of Biochemistry and Molecular Biology, Jahangirnagar University, Savar, Dhaka. The experiment was conducted before and after the Arabic month, Ramadan, when there occurs a change both in the pattern and timing of dietary intake. Findings of the study shows Ramadan fast significantly reduced serum Low Density Lipoprotein (LDL-C) (p = 0.011). A statistically non significant reduction of total Cholesterol (TC) (p = 0.340), small elevation of High Density Lipoprotein (HDL-C) (p = 0.252) and Triglyceride (TG) (p = 0.502) were also observed. Considering the findings of the study it was noticeable that one month Ramadan fast can improve lipid profile status of blood and hence able to improve atherosclerotic diseases which includes hypertension, ischemic heart disease and stroke.

Introduction: Family Planning is a national strategy of Indonesia government to manage the population growth. Depo Medroxyprogesterone Acetate (DMPA) is one of injectable contraceptives most widely used because it is simple and easy to obtain. However, it has various side effects causing imbalance of hormone estrogen, in turns to result in a decrease in HDL (High Density Lipoprotein) and an increase in LDL (Low Density Lipoprotein) which will result in an increase in total cholesterol. It will also affect changes in fat metabolism in human body due to hormonal influences. This results in dyslipidemia and atherosclerosis. Method: The method in this study is an experimental study with a pretest-posttest control group design. Results: The purpose of this study was to determine the relationship between duration of use of DMPA injections with lipid profile levels in mice. The data were analyzed by using the Paired t-test parametric test to compare between treatment groups. This study found that there were significant differences in HDL levels and total cholesterol levels between before and after administration of DMPA injections on the 14th and 35th days. There is a significant relationship between the duration of administration of DMPA injections with HDL levels and total cholesterol levels in mice. However, there was no difference in LDL levels and triglyceride levels between before and after administration of DMPA injection on day of 14 and day of 35, while, there was a significant difference between before and after the 35th day. There is no relationship between duration of administration of DMPA injections with LDL levels, while there is a relationship among mice triglycerides. Conclusions: Administration of DMPA injections for a long time lowers HDL.

There are numerous studies concerning the effect of UVB light on skin cells but fewer on other skin components such as the interstitial fluid. This review highlights high-density lipoprotein (HDL) and low-density lipoprotein (LDL) as important targets of UVB in interstitial fluid. Tryptophan residues are the sole apolipoprotein residues absorbing solar UVB. The UVB-induced one-electron oxidation of Trp produces•Trp andO2•-radicals which trigger lipid peroxidation. Immunoblots from buffered solutions or suction blister fluid reveal that propagation of photooxidative damage to other residues such as Tyr or disulfide bonds produces intra- and intermolecular bonds in apolipoproteins A-I, A-II, and B100. Partial repair of phenoxyl tyrosyl radicals (TyrO•) byα-tocopherol is observed with LDL and HDL on millisecond or second time scales, whereas limited repair ofα-tocopherol by carotenoids occurs in only HDL. More effective repair of Tyr andα-tocopherol is observed with the flavonoid, quercetin, bound to serum albumin, but quercetin is less potent than new synthetic polyphenols in inhibiting LDL lipid peroxidation or restoringα-tocopherol. The systemic consequences of HDL and LDL oxidation and the activation and/or inhibition of signalling pathways by oxidized LDL and their ability to enhance transcription factor DNA binding activity are also reviewed.
