Combined therapy of statins and shrimp wing oil in mixed dyslipidemia

Dyslipidemia is recognized as a leading risk factor for the development of cardiovascular disease, and current guidelines focus on lowering LDL cholesterol. Statins are the first choice for lowering elevated LDL cholesterol levels, however, a new approach to treating dyslipidemia involves combining proven therapy with new natural therapeutic options.

• • A new approach to the treatment of dyslipidemia → combining statin therapy and new natural therapeutic options

• • Shrimp wing oil can lower triglycerides (TGL), increase HDL cholesterol and improve endothelial function

• • omega-3 fatty acid preparations, such as shrimp wing oil, are a preferred natural therapeutic option because they do not cause gastrointestinal side effects

• • Combining different approaches to lowering blood lipids such as statins and shrimp wing oil increases the chances of achieving a better lipid profile of the patient

• • Shrimp wing oil contains highly bioavailable EPA and DHA and the antioxidant astaxanthin

Benefits of shrimp wing oil

Numerous scientific studies have shown that shrimp wing oil has a beneficial effect on human health.While fish oil contains biologically valuable omega-3 fatty acids EPA and DHA in the form of triglycerides or ethyl esters, shrimp wing oil contains phospholipid forms of EPA and DHA, mainly in the form of phosphatidylcholine. Their polar structure ensures greater bioavailability of EPA and DHA fatty acids compared to fish oil (1). An additional advantage of shrimp wing oil is the natural content of the antioxidant astaxanthin, which, among other things, increases the stability of omega-3 fatty acids and protects them from oxidation. Ingestion of fish oil often causes gastrointestinal side effects such as reflux, however, shrimp wing oil in the form of a dietary supplement, especially the one that comes in Licaps® capsules, does not leave a characteristic fishy smell and taste or reflux after consumption.

Shrimp wing oil can increase HDL cholesterol and improve endothelial function

Shrimp wing oil has hypolipemic properties and has been shown to reduce serum triglycerides as well as total cholesterol and LDL cholesterol. Also, one of the benefits is that shrimp krill oil can increase HDL cholesterol (2). Epidemiological studies have shown that in addition to elevated LDL cholesterol, a low level of HDL cholesterol is an independent risk factor for the development of coronary heart disease. The level of HDL cholesterol is strongly inversely related to the rate of cardiovascular events (3).

Shrimp wing oil can lead to a moderate reduction in cardiovascular risk by improving endothelial function and increasing HDL cholesterol in people with type 2 diabetes who have a high incidence of cardiovascular disease (4). In the journal BMJ Open Diabetes Research & Care, in 2015, the results of a randomized double-blind study in which 47 subjects participated were published. In subjects who ingested shrimp wing oil for 4 weeks, there was an improvement in endothelial function and a decrease in C-peptide levels and the HOMA index compared to placebo (olive oil). The HOMA index model is an insulin resistance test that assesses the state of existing beta cell function and insulin sensitivity using data from fasting glucose and insulin levels.

A total of 34 subjects continued to consume shrimp wing oil for 17 weeks, and it was shown that in these subjects there was a significant improvement in endothelial function and an increase in HDL cholesterol.

Effect of shrimp wing oil on triglycerides

In people with mixed dyslipidemia, after monotherapy with statins, persistent hypertriglyceridemia may occur, and elevated triglycerides are also an independent risk factor for the development of cardiovascular diseases (5).

In the journal Nutrition Research in 2014, a study was published on the influence of shrimp wing oil on the level of serum triglycerides, and the results of the omega-3 index in the subjects were also published.A double-blind, randomized clinical trial involving 300 subjects with high triglyceride levels tested 4 doses of shrimp wing oil (0.5 g, 1 g, 2 g, or 4 g) over 12 weeks, while the placebo was olive oil. Compared to placebo, shrimp wing oil reduced the level of triglycerides by 10.2%, and it is important to emphasize that there was no effect on LDL cholesterol. The most important discovery of this research was an increase in the omega-3 index in the group that consumed shrimp wing oil by 8, 18, 29 and even 73% depending on the dose taken, while in the group that consumed the placebo there was a decrease in the omega-3 index by 3%.

Despite the fact that the researchers ultimately, for the sake of stronger statistical power of the test, analyzed the aggregate results of all four intervention groups that took shrimp wing oil regardless of the dose, we can conclude that the addition of shrimp wing oil can improve the triglyceride status, which makes it a good choice of supportive therapy in addition to statins with the aim of lowering multiple lipid abnormalities (6).

Efficacy and safety of combination therapy compared with statin monotherapy

A 2018 systematic meta-analysis assessed the safety and efficacy of statin monotherapy and combination therapy with statins and omega-3 fatty acids in dyslipidemia. A total of 6 studies were included in the analysis, and the combination of 4 g of omega per day with 20-40 mg of statins was examined. The scientists concluded that the combination of statins and omega-3 fatty acids led to a significant reduction in the ratio of total cholesterol to HDL cholesterol. There was no difference in the level of LDL cholesterol in both groups, however, subjects who took statins in combination with high-dose omega-3 fatty acids had a significantly higher number of gastrointestinal side effects (7).

The combination of statins and omega-3 fatty acids improves the lipid profile, but due to safety issues, the recommendation of high doses of omega-3 fatty acids was not included in clinical guidelines, as high doses of omega-3 failed to further lower LDL cholesterol, which is the most important factor for the prevention of cardiovascular diseases and related deaths. Therefore, lower-dose preparations of omega-3 fatty acids are a desirable natural therapeutic option, mainly due to the lack of gastrointestinal complaints. Furthermore, the benefits of omega-3 fatty acids from shrimp wing oil certainly contribute to the effect of drug therapy, which is anti-inflammatory and antioxidant and lowers triglyceride levels.Combining different lipid-lowering approaches increases the chances of achieving a better individual's lipid profile, and therefore the comparative use of statins and shrimp wing oil is a recommended cardioprotective strategy (8).

Conclusion

When thinking about which additional natural active substance to introduce in therapy with the aim of lowering elevated blood lipids, along with statins, omega-3 fatty acids in the form of shrimp wing oil are imposed as a logical, safe and effective choice precisely because of additional improvements in lipid status without the need for laboratory tests and without side effects (9).
