1. The current state of knowledge on statins, therapeutic solutions in the dyslipidaemia of type 2 diabetes.

1.1. Diabetes and cardiovascular risk

In type 2 diabetes mellitus (DM 2) leading cause of mortality is

generated by the clinical consequences of atherosclerosis. LDL

cholesterol and atherosclerosis are related both to the healthy people

and those with diabetes, only those with DM 2 predisposition for

atheromatosis is higher, although their levels of LDL are similar to

those of healthy people. Atherosclerosis begins with endothelial

dysfunction, lipid accumulation in macrophages and an inflammatory

response, leading to plaque formation and narrowing of the vascular

lumen. Less resistant plates will crack and could lead to myocardial

infarction (MI) or stroke. Atherosclerotic cardiovascular disease is the

leading cause of morbidity and mortality in patients with type2 diabetes,

and the risk of developing the disease is two to four times higher than

in non-diabetic subjects [1]. In addition, the risk of cardiac morbidity

and mortality in individuals with type 2 diabetes without previous MI

has been shown to be similar to that in non-diabetic subjects with a

history of MI [1]. Several prospective studies have shown that cross a

preponderance of small LDL particles is associated with an increased

risk of coronary artery disease (CAD) and Diabetes Atherosclerosis

Intervention Study (DAIS, 2003) reported that small LDL particles are

significantly associated with progression of the disease [2].

LDL particle size can be used with LDL cholesterol determination,

to give an indication of the number of circulating LDL particles. Two

individuals may have the same concentration of LDL-cholesterol, but

that with predominantly small LDL particles will need more particles to

carry the same amount of cholesterol.

The observation that diabetics have small particles of LDL but

normal plasma levels of LDL-cholesterol, shows that particle number is

increased in type 2 DM.

1.1.1. LDL oxidation and oxidative stress LDL oxidation initiates a series of events that ultimately will lead

to increased acquisition of LDL by macrophages, the formation of

foamy cells and the development board aterom [3]. Oxidized LDL and

antibodies against the modified form of the lipoproteins were found in

atherosclerotic lesions [4], but not in normal arteries or veins. Some

characteristics of oxidized LDL play a role in the development of

atherosclerotic plaques: oxidised LDL is toxic for endothelial cells [5],

recruits lymphocytes in atherosclerotic lesions [6] and promotes

proliferation of macrophages within plaques [7].

1.1.2. LDL oxidation and association with atherosclerosis and diabetes

Small and dense LDL particles are considered more prone to

oxidation than large ones and at least three studies have shown an

inverse relationship between lag phase of LDL oxidation and LDL

density [10]. Using LDL split, these studies show that small and dense

LDL particles are less resistant to in vitro oxidation than large LDL

particles, energetic harvested from the same individual.

Plasma levels of oxidized LDL, measured by ELISA-sandwich

were increased in individuals with impaired glucose tolerance (TAG)

compared with control subjects after adjusting for age and body mass

index (BMI), and increased in patients with type 2 DM with

macroalbuminuria than in those with normo-or microalbuminuria and

healthy subjects [13]. Patients with well controlled DM have increased

plasma levels of oxidized LDL compared with control subjects, when

adjusted for LDL-cholesterol concentration [15, 16]. Moreover, it was

observed an inverse relationship between circulating levels of LDL and

oxidised LDL particle size in patients with DM 2 [16]. The middle-aged

men observed an independent association between serum oxidised

LDL and subclinical atherosclerosis assessed by intimate-media

thickness at common carotid artery [14].

1.1.3. Conclusions and perspectives There is evidence of increasingly numerous, showing that

changes in LDL increase aterogenitatea. Since the modified LDL is not

a homogeneous entity, no single diagnostic marker that adequately

reflect the risk of cardiovascular disease associated with modified LDL.

The presence in plasma of small dense LDL particles is

associated with hypertriglyceridaemia and an increased risk of

coronary artery disease (CAD). Small LDL particles predominate in

patients with insulin resistance and an inverse relationship has been

observed between LDL particle size and circulating oxidised LDL

particle number in patients with type 2 diabetes [16]. LDL particle size

may be influenced favorably by establishing a strong control of blood

glucose [17]. This supports the importance of glycemic control benefits

above and beyond established microvascular disease. LDL particle

size is increased fenofibrat [2], while therapy with statins, although

significantly reduce the total level of LDL cholesterol, not affecting

Page 6: Appreciation efficacy and safety of statin therapy in ... efficacy and safety of statin... · Appreciation efficacy and safety of statin therapy in lowering cardiovascular risk in

their size [18].

In conclusion, LDL cholesterol is a poor predictive factor for CAD

risk assessment associated with DM 2. Some oxidative and non-

oxidative modification of LDL, as oxidation and glycation contributes to

accelerating atherosclerosis in diabetes. Measuring these changes in

LDL is very technically demanding and therefore unsuitable for routine

practice. Serum triglycerides are closely related to the predominance

of small LDL particles and increased levels of oxidised LDL. In addition,

the number of LDL particles is positively correlated with risk of CAD.

1.2. Inflammatory biomarkers predictive of acute cardiovascular events

1.2.1. C-reactive protein (CRP) and cardiovascular risk in type 2 diabetes

Development high-sensitive CRP (hs-CRP) by a stable and

cheaper method, increased ability to obtain more useful determinations

of circulating levels of this cytokine and therefore redefine the

assessment of cardiovascular risk, particularly those where the risk is

intermediate, as individuals with medium LDL-cholesterol levels.

CRP is considered to be an important inflammatory cytokine,

which acts as a nonspecific defense mechanism in response to

permanent damage or infection tissue. Synthesized primarily in the

liver, CRP activity is stimulated by other cytokines, particularly

interleukin IL-6, IL-1β and tumor necrosis factor-α (TNF-α). CRP binds

to a variety of other molecules, particularly liposomes and lipoproteins,

the LDL and VLDL cholesterol and is a potent activator of classical

complement pathway. The data accumulated suggest that CRP, which

Some data [26], reinforcing the concept that inflammation plays

an important role in the pathogenesis of type 2 diabetes and linking

diabetes with concomitant states there is an inflammatory component

[27]. There is evidence that insulin resistance with normal glycemia is

an proinflammatory state and there with long before the actual onset of

type 2 diabetes [28]. The mechanism has a major role in the

inflammatory cascade of events leading to rupture aterom plate. Up-

regulation of receptor for advanced glycation and products (AGES)

was associated with increased inflammatory reactions. Increased

expression of these receptors was correlated with poor control of

blood glucose and could contribute to the area of complex

is also found in macrophages from the ateroma plaque is associated

atherothrombosis as concerned or mechanism.

1.2.2. CRP - predictor of cardiovascular events

Moderate increases in CRP can be found even in apparently

healthy people [6]. A progressive increase of CRP may reflect vascular

inflammation amplification stages, but specific clinical conditions in

which the event is not fully understood. Although LDL cholesterol

remains a major risk factor for cardiovascular disease, at least one

third of coronary events occur in individuals with an LDL level below

130 mg/dl [25], which is generally considered a medium level in

individuals without known coronary artery disease. Monitoring levels of

CRP in these clinical conditions can be very useful for risk assessment.

Evidence that CRP levels are elevated during cardiovascular and

cerebrovascular events suggests that CRP is valuable in predicting the

subsequent evolution of these events.

mechanisms that lead to acceleration of atherosclerosis in patients

with diabetes [29].

1.2.4. Conclusions and perspectives

Current Opinions differ regarding the value of CRP test additive,

in addition to classical risk factors for cardiovascular risk assessment.

Continue discussion on the use of CRP as part of screening for global

risk assessment.

1.3. Lipid and non-lipid effects of statins in the prevention of cardiovascular pathology

1.3.1. Statin-brief history, definition, mechanisms of action

First clinical experience of administration of statins was held in

1976, and since the 80 trials were initiated extensive research of the

effects of statins in U.S. clinics. The emergence of 3-hydroxy-3

inhibitors -metilglutaril-coenzyme A reductase inhibitors (statins) has

revolutionized treatment of hypercholesterolemia. In the liver, statins

specifically inhibit competitive, reversible HMG-CoA reductase, the

enzyme that catalyzes the conversion of HMG-CoA (hydroxymethyl-

glutaryl coenzyme A) to mevalonic acid, limiting stage the formation of

cholesterol [37]. By decrease in cholesterol synthesis, statins also

reduce, the formation of lipoproteins, especially LDL and VLDL.

Because diabetes is considered equivalent for heart disease,

aggressive treatment of dyslipidemia (especially when using statins) to

reduce coronary risk, is a priority in the care of diabetic patients.

Observations of large-scale randomized clinical trials underlying of

recommendations of international guidelines that support the need and

importance of reaching lipid targets all people with diabetes. Lipid

control is part of multifactorial management of diabetes, which should

be early and intensive.

1.3.2. Statins and diabetes

Endothelial dysfunction is representative of the DM and insulin

resistance and is characterized by reduction effective action of nitric

oxide. Hyperglycemia status implies a cascade of mechanisms leading

to increased vascular tone. In patients with DM statins improve

endothelial dysfunction by stimulating NO production by endothelial

cells, modulating the release and action vasoconstrictors.

2. Own contributions

2.1. Motivating the study and current working hypothesis Is well studied many effects of statins: lipid-lowering, anti-

inflammatory, antiproliferative, antioxidant, immunosuppressive,

positive influence on rheological parameters and thrombogenesys,

correction of endothelial function. These effects have been well studied

in patients with ischemic heart disease and less in patients with type 2

diabetes. How atherosclerosis is a diffuse process, serum biomarkers

have the potential to provide a general measure of risk that can allow a

more targeted, with a variety of techniques focused on those with

abnormal levels. In addition, they can provide an overall assessment of

treatment response to various interventions. Serum biomarkers are

likely to play an important role in the future, risk stratification and

prognosis of cardiovascular disease, especially when established risk

factors are complementary. Compared to invasive or noninvasive

procedures, their evaluation has the advantage of being relatively free

Page 10: Appreciation efficacy and safety of statin therapy in ... efficacy and safety of statin... · Appreciation efficacy and safety of statin therapy in lowering cardiovascular risk in

9

of risks, less expensive, and applicable to a wide range of populations

at risk.

Although it was shown that treatment with statins reduce CRP

levels in a manner that is largely independent of LDL cholesterol level,

lack of evidence linking a greater reduction in CRP levels by reducing

the rate of cardiovascular events.

Provocative information now suggests that hsCRP is useful in

monitoring the effectiveness of statins in primary prevention, after the

stent implantation, and in increased risk of acute coronary syndromes.

Applying biology of inflammation in atherosclerosis has already

provided a new perspective on how current interventions, both

pharmacological and in lifestyle can reduce cardiovascular risk. There

are no studies that examine various lipid or non-lipid effects of statins,

according to the dose administered to prevent acute cardiovascular

events (especially the influence of hs-CRP and oxidized LDL) in

patients with type 2 diabetes with or without dyslipidemia or who

suffered a heart attack or stroke.

There is data showing the association between blood levels of

hs-CRP and LDL-ox, and that would be predictive value for the

cardiovascular risk of the two biomarkers together, in diabetic patients.

2.2. Study Objectives 1. Evaluation of inflammatory biomarkers (hs-CRP), of oxidative

stress (oxidized LDL), lipids (cholesterol, triglycerides), blood glucose

(blood sugar, HbA1c) and hepato-renal (ALT, AST, microalbuminuria)

The study included 84 patients with type 2 diabetes, of whom 43

patients without acute cardiovascular events (group A) and 41

patients with type 2 diabetes without manifest cardiovascular disease

and those with heart attack or stroke.

3. The changes that inflammatory biomarkers (hs-CRP), oxidised

LDL, the metabolism of blood glucose and lipid parameters in patients

untreated with lipid-lowering drugs and patients treated with

atorvastatin.

patients with acute cardiovascular events (group B). In each of the two

study groups were distinguished two subgroups: patients who not

received lipid-lowering medication (A1, B1) and patients treated with

atorvastatin (A2, B2).

Diagnosis of type 2 diabetes was based on historical data,

clinical and laboratory explorations. The absence of cardiovascular

disease was defined as documented absence of myocardial infarction,

stroke or peripheral arterial disease. Retinopathy and nephropathy

have been refuted by practitioners.

The average age of patients included in the study was 61.12 ±

11.38 years (age limits - 39 and 84 years), with significant difference

between the two groups: the group A (without acute cardiovascular

events) mean age was 53.61 ± 6.68 years and in group B (acute

cardiovascular events) mean age was 69.88 ± 9.27 years. The gender

distribution showed a predominance of women in group A vs. 61.9%.

38.1% and a high proportion of men in group B 72.22% vs.. 27.78%.

1. Type 2 diabetes is a complex disease associated with an

increased risk of ischemic heart disease and premature death. Among

patients with acute coronary syndrome and stroke have predominantly

In this study we evaluated the efficacy and safety of atorvastatin

in lowering cardiovascular risk, given at a dose of 10 mg/day and 20

mg/day on lipid metabolism, glycemic and inflammatory biomarkers in

patients with type 2 diabetes without manifest cardiovascular disease

and in patients with acute cardiovascular events, which were given

treatment for a period between 4 and 24 weeks.

In our study we found evidence of benefit for patients whose

treatment with statins resulted in concentrations of hs-CRP of less than

2 mg/l, whether levels of LDL cholesterol were reduced to the target

value of less than 70 mg/l or not. In this respect, our data are

consistent with research witch indicating inflammation as a factor of

plaque instability and experimental data showing that statins, in

addition to lipid lowering effect, also have important anti-inflammatory

effects [42].

In our study, oxidized LDL levels were significantly higher values

in diabetic patients untreated with lipid-lowering compared with diabetic

patients treated with atorvastatin, regardless of cardiovascular status.

Significant changes in this biomarker were recorded depending on the

dose of atorvastatin in type 2 DM patients without manifest

cardiovascular disease (A2) - 10 mg/day: 70.75 ± 3.32 U/l vs. 20

mg/day: 60.24 ± 7.54 U/l.

men aged 60-80 years.

2. In acute cardiovascular events diabetes is not only an

important cardiovascular risk factor, but has a strong impact on other

risk factors- hypertension, elevated total cholesterol, triglycerides, low

HDL-cholesterol- showing a tendency to associate their the same

patient.

3. Glicate hemoglobin and blood sugar levels, total cholesterol

and LDL cholesterol were not significantly affected by the dose of

atorvastatin administered, but blood glucose was as high as the

effectiveness of statins in reducing lipids was lower.

4. Patients with received low-dose atorvastatin (10 mg/day or 20

mg/day) long term (12-24 weeks) had lower blood glucose levels

(statistically insignificant) than those who received short-term treatment

(4-8 weeks)

5. The group of patients without manifest cardiovascular disease,

diabetes mean age was 42.61 ± 57.86 months and the group of

patients with acute cardiovascular events 29.05 ± 49.49 months, which

proves, surprisingly and contrary data literature, that age of type 2

diabetes does not influence the incidence of acute cardiovascular

events. Myocardial infarction or stroke, in diabetic patients, may occur

regardless of age diabetes, but dependent on the existing metabolic

imbalance.

9. Oxidized LDL and hs-CRP were significantly elevated in

patients with acute myocardial infarction or stroke than those without

manifest cardiovascular disease, irrespective of lipid profile of patients,

suggesting that may be considered independent predictive factors for

cardiovascular risk.

10. Our research findings suggest a higher sensitivity of hsCRP

at atorvastatin therapy compared with oxidized LDL, both in patients

without manifest cardiovascular disease, and especially in patients with

acute MI or stroke.

11. Treatment with statins reduce hsCRP levels in a manner that

is largely independent of LDL cholesterol level, but lack of evidence

linking a greater reduction in hsCRP levels by reducing the rate of

cardiovascular events.

15. Statins exercise beneficial pleiotrope effects on vascular wall

cells. Treatment with statins was one of the most significant advances

in prevention and treatment of atherosclerosis. The benefits of statin

therapy in reducing cardiovascular risk extend beyond their effects on

serum lipids.

16. In general, statins are well tolerated drugs, the primary side

effect is hepatotoxicity, which increases in direct proportion to the dose

of statin administered and seems to not be influenced by the duration

of treatment.

17. Atorvastatin, at doses of 10 mg/day and 20 mg/day, did not

cause a deterioration in the biological samples of liver (ALT, AST),

requiring discontinuation of therapy.

18. Because clinical trials with statin therapy was initiated only on

total cholesterol and LDL cholesterol, suggest that evaluation of

biomarkers hsCRP and oxidized LDL is an objective way to assess the

need for administration of statins, and establishing the effectiveness of

statins in preventing acute cardiovascular events.
