Abstract
The invention concerns the use of essential fatty acids with a high content in eicosapentaenoic acid ethyl ester (EPA) or docosahexaenoic acid ethyl ester (DHA) useful for preventing of cardiovascular events in patients with diabetes mellitus.
Description
Use of Omega-3-Fatty Acids in the Treatment of Diabetic Patients DESCRIPTION
This invention concerns the use of a pharmaceutical composition containing essential fatty acid ethyl esters originating from fish oils, in particular as a high concentration mixture of ethyl esters of (20:5w 3) eicosapentaenoic acid (EPA) and (22:6w 3) docosahexaenoic acid (DHA) in patients who suffer from diabetes.
It is well known that certain essential fatty acids confiained in fish oil have a fiherapeutic effect in the prevention and treatment of cardiovascular disorders, such as in the treat-ment of hypertension, thrombosis, hypercholesterolemia, arteriosclerosis, cerebral in-farction, prevention of sudden death in post myocardial infarction patients, improve-ment of endothelial function and hyperlipedemias.
US Patents US 5,502,077, US 5,656,667 and US 5,698,594 can be quoted as exam-ples. The prevention of cardiovascular events, especially of mortality in patients who have survived the hospitalization phase of acute myocardial infarction (ARdll) is de-scribed in the international patent application'JVO 00/48592.
The above prior art in particular provide knowledge about the utility of fatty acids be-longing to the cal-3 family, more specifically (20:5w 3) eicosapentaenoic acid (EPA) and (22:6t~J 3) docosahexaenoic acid (DNA), in treating the above-mentioned disorders.
The fatty acid EPA, being a precursor of PG13 and TxA3, exerts a preventing platelet aggregation effect and an antithombotic effect that can be ascribed to inhibition of cyclooxygenase (similar effect to that of aspirin) andlor to competition with arachidonic acid for this enzyme, with consequent reduction in the sythesis of PGE2 and TxA2, which are well known platelet aggregating agents.
On the other hand the fatty acid DHA is the most important component of cerebral lip-ids in man and furthermore, being a structural component of the platelet cell it inter-venes indirectly in increasing platelet fluidity, thus playing an important role in an-tithombotic activity.
The international patent application WO 89/11521, whose description is herein incorpo-rated by reference, describes in particular an industrial process for extracting mixtures with a high content in poly-unsaturated acids, including EPA and DHA and their ethyl esters, from animal andlor vegetable oils.
Mixtures of fatty acids, especially EPA/DHA, obtained according to WO
89/11521, are reported to be particularly useful in the treatment of cardiovascular diseases.
However, current methods of treatment used in human therapy have been shown to be insufficient in patients who have a diabetes mellitus, in particular in those patients in whom it is desired to also prevent cardiovascular events. It is well known that patients with diabetes, in particular with diabetes mellitus, are at a substantially increased risk of cardiovascular events and death.
Therefore, there still is a substantial need for improved and effective treatments with drugs, in particular for preventing these recurrences. Object of this invention, therefore, is to provide such improved and effective treatment of diabetic patients.
This invention, therefore, suggests the novel use of essential fatty acids with a high content in EPA-ethyl ester or DHA-ethyl ester or a high concentration mixture thereof, in the preparation of a medicament useful for the treatment of patients suffering from diabetes. In particular, the invention is directed to preventing cardiovascular events in patients who have diabetes mellitus.
For ease of description "EPA-ethyl ester and "DHA-ethyl ester" will be also quoted here as °'EPA" and "DHA".
In particular this invention pertains to the use of essential fatty acids containing a mix-ture of eicosapentanoic acid ethyl ester (EPA) and docosahexaenoic acid ethyl ester (DNA) in the preparation of a medicament useful for the treatment of patients suffering from diabetes, preferably for preventing cardiovascular events in patienfis who have diabetes, where the content in EPA and DHA in such mixture is greater than 25%
b.w.
An essential fatty acid with high content in EPA or DHA, according to the present in-vention, preferably contains more than 25°!° by weight (b.w.), in particular from about 60 to about 100% of such ester. These compounds can be obtained by known meth-ods.
In an essential fatty acid with a high concentration mixture of EPA and DHA, preferably such mixture has a content in EPA and DHA greater than 25% by weight, in particular from about 30 to about 100% by weight, preferably about 85% by weight.
In the EPA/DHA mixture, EPA preferably is present in a percentage from about 40 to 60% by weight and DHA, preferably in a percentage from about 25 to about 45-50%.
In any case the preferred EPA/DHA ratio in such EPAIDHA mixture is about 0.9/1.5.
PHARMAC~L~~Y
Diabetes mellitus has become an increasingly prevalent disease worldwide. The preva-lence of diabetes is increasing rapidly and the number of individuals with type II diabe-tes (80-90% of all diabetic people) is depicted to reach 300 million in the year 2025, accounting for 5.4% of the global population. Furthermore, cardiovascular events are important contributors to morbidity and mortality in patients with diabetic disease. The risk of death from cardiovascular disease is in patients with diabetes two to six times that among persons without diabetes. Currently, over 50% of diabetic patients die from coronary heart disease. In contrast to non-diabetic people, coronary heart mortality has not declined in diabetic people. Type II diabetes eliminates the protective advantage of female sex against coronary heart disease mortality. The prognosis after a coronary heart disease event is poorer in diabetic people than in non-diabetic people.
V9lithin 1 year after an acute myocardial infarction, 44..2% of type II diabetic men and 38.9% of type II diabetic women die.
All manifestations of coronary heart disease are at least twice as common in pafiients with diabetes as in non diabetic individuals. Moreover, recently close interrelations be-tween diabetes and cardiovascular disease, not at least with coronary artery disease, were elucidated. It has been demonstrated in a number of studies that 28% of patients with known coronary artery disease have diabetes, and as many as 70% of patients with acute coronary syndromes have abnormal glucose metabolism, either in the form of diabetes or impaired glucose tolerance. Major risk factors for coronary heart disease in patients with diabetes are:
1. unfavorable lipoprotein profile, characterized by increased serum triglycerides;

Major risk factors for coronary heart disease in patients with diabetes are:
1. unfavorable lipoprotein profile, characterized by increased serum triglycerides;
2. elevated blood pressure;
3. predisposition to formation of thrombosis, including the following manifestations:
high concentrations of plasminogen activator-1 and cytokines;
high concentrations of plasminogen activator-1 and cytokines;
4. impairment of endothelia-dependent vasodilatation;
5. cardiac autonomic impairment leading to decreased ischaemic pain perception, higher heart rate and decresed heart rate variability, which in turn increases the risk for sudden death.
The efficacy of the treatment, according to the present invention, is proven by ample pre-clinical and clinical evidence:
1. EPA plus DHA induces a reduction in the levels of triglycerides and of very-low density lipoprotein cholesterol (VLDL) in patients with hypertriglyceremia;
2. EPA plus DHA does lower blood pressure in patients with hypertension;
3. Dietary EPA and DHA down-regulate gene expression of platelet-derived growth factor-A and of platelet-derived growth factor-B in human mononuclear cells;
4. ~upplemeniation with EPA plus DHA mitigates the course of coronary athero-sclerosis in patients with coronary heart disease;
5. EPA and DHA improves endothelial function in heart transplant recipients.
ft. Experimental studies have shown that EPA and DHA are antiarrhythmic in sev-eral animal models, probably due to specific modulation of ion currents;
7. EPA and DHA increases heart rate variability in healthy volunteers and in survi-vors of a myocardial infarction;
8. EPA plus DHA decreases the incidence of sudden death in survivors of a myo-cardial infiarction.
The above mentioned evidence of reducing risk fiactors shows that the present inven-tion provides a new and valuable therapeutic tool for treating diabetic patients, and in particular for preventing cardiovascular events in diabetic patients.
Accordingly, this invention also provides a method for treating diabetic patients, pref-erably patients with diabetes mellitus and in particular for preventing cardiovascular events in diabetic patients, preferably in patients with diabetes mellitus, comprising administering to such patient a therapeutically effective amount of a medicament con-taining essential fatty acids with a high content in EPA-ethyl ester or DHA-ethyl ester or a high concentration mixture thereof.
