[In the fight against atherosclerosis, statin therapy is one of the most important elements. On the basis of data from the past few years the clinical introduction of a more effective statin is not expected, however, in order to improve cardiovascular prevention further development of agents that reduce LDL-cholesterol levels more effectively than currently used statins is warranted. The need for the development of new cholesterol-lowering therapeutic options is also supported by the existence of statin intolerance. The currently available combination therapies do not provide additional mortality benefits compared with statin monotherapy. The new solutions include fourth-generation statin molecules that primarily aim to enhance the NO-donor capacity of statins, and to reduce their muscle toxicity. Certain compounds that affect cholesterol synthesis (squalene synthase inhibitors, MTP inhibitors, ACAT inhibitors) need to be further analysed because of the risk of side effects. The use of an antisense oligonucleotid that blocks the mRNA of apoB, the main protein on the LDL-particle and antibodies that inhibit the protein PCSK9 that promotes the intracellular breakdown of the LDL-receptor seems to be much more promising. Besides the lowering of LDLcholesterol level, studies have focused on the benefits of increasing HDL-cholesterol levels. Unfortunately, recently completed analyses show that new forms of the strong HDL-C increasing nicotinic acid have not provided any additional benefit when added to statin therapy. Similarly, the adverse effects associated with the promising CETP inhibitors and the lack of additional benefit when combined with statins question the significance of this drug class. The necessity for an absolute increase of HDL-cholesterol levels needs to be revised on the basis of new data, in other words, the exact role of the HDL particle in atherosclerosis needs to be further investigated.]

[A remarkably successful therapy with gliclazid treatment in type 2 diabetes mellitus]

KIS János Tibor

[INTRODUCTION - Sulfonylureas have become sidelined as second-line preparations as their use has been associated with an increased occurrence of weight gain and hypoglykaemia. In the case reported, however, therapeutic goals have been achieved with the use of gliclazid. CASE REPORT - A 45-year-old man with type 2 diabetes mellitus was using a metformin XR preparation. His HbA1c level was high and his main complaint was distention. His abdominal complaint was also obstructing his diet. Because of the high HbA1c level and overweight I initiated incretin-mimetic treatment. Due to the worsening of abdominal complaints I replaced the treatment with gliclazid, after thoroughly informing the patient. With gliclazid treatment the patient's abdominal complaints subdued, he was able to maintain his diet, lost 14 kg in three months and the parameters of his carbohydrate metabolism normalised. CONCLUSION - In case of abdominal complaints, a repeated anamnesis of the diet can reveal metformin intolerance. In such cases, the use of gliclazid can lead to therapeutic success with no gastrointestinal adverse effects.]

[Anti-atherosclerotic effects of Ca-antagonists in the light of new clinical data]

ALFÖLDI Sándor

[Based on in vitro and animal research, it has been found that calcium antagonist drugs are capable of inhibiting directly the atherosclerotic process. In spite of their advantegous antiatherosclerotic effect, the fast-release, first-generation dihydropyridines had an unfortunate effect on the number of newly developed myocardial infarctions and on cardiovascular mortality. New, controlled clinical studies have found long acting calcium antagonists to decrease significantly the progression of the atherosclerosis in the carotid artery - verified with B-mode ultrasound scans - and the appearance of cardiovascular clinical events, when either proven coronary sclerosis (PREVENT, CAPARES studies) or hypertension (INSIGHT, ELSA, VHAS) was present. If further clinical trials (CAMELOT, NORMALISE - now under way) justify these promising clinical data, then long-acting calcium channel blockers may become new and significant tools in the prevention of the progression and clinical complications of atherosclerotic disease.]

[SIGNIFICANCE OF MICROCIRCULATION IN ARTERIAL DISEASES]

FARKAS Katalin

[The microvascular bed is an anatomical entity, which constitutes of blood vessels smaller than 50 μm (i.e. arterioles, capillaries and venules), and its major function is the nutritive perfusion of organs and tissues. In search of cardiovascular diseases, there are growing evidences that impaired microcirculation plays an important role in the patophysiology of arterial diseases. Beside the well known consequence of diabetic microangiopathy in the development of diabetic complications, new data support the role of microcirculation in the pathogenesis of hypertension and atherosclerosis, as well. There are different non-invasive methods for the investigation of the microcirculation. Capillarmicroscopy, laser doppler flowmetry and transcutaneous oxygen pressure measurement are used not only in the scientific research, but also in the clinical practice. Laser doppler flowmetry gives us the possibility to assess microvascular endothelial function and other early microcirculatory disturbances. Capillarmicroscopy is particularly useful in the diagnosis of different autoimmune diseases. Transcutaneous oxygen pressure measurement is mostly used in the diagnosis of critical limb ischemia, because it has proven prognostic relevance. Vascular specialist should prescribe all investigations. General practitioners play key role in the early diagnosis of vascular diseases that can be achieved through the screening of patients at risk for vascular disease. In case of suspected vascular disease, the patient should refer to angiology outpatient clinic, to decide further investigations and prescribe therapy. The conservative treatment includes the complex cardiovascular risk management supplemented with medication, acting on the microcirculation.]

[UNSOLVED THERAPY - COMPLEX TREATMENT OF BUERGER’S DISEASE]

SZOMJÁK Edit, DÉR Henrietta, KEREKES György, VERES Katalin, DEZSŐ Balázs, TAKÁCS István, TÓTH Judit, MÓZES Péter, SOLTÉSZ Pál

[INTRODUCTION - Buerger’s disease is a nonatherosclerotic, segmental, inflammatory, progressive obliterative disease of the blood vessels that most commonly affects the small and medium-sized arteries and also the veins of the lower limb. It is strongly associated with tobacco use. CASE REPORT - A 37-year-old heavy smoker forest worker presented with severe gangrenous changes on the fingers as the upper limb manifestations of Buerger’s disease, which required acral amputation. After complex medical treatment, pharmacological sympathectomy on the left side and surgical sympathectomy on the right side, bilateral conserving necrectomy, cessation of smoking and 2 cycles of cyclophosphamid, the patient's status significantly improved, his pain diminished and, although to a limited extent, he could use both hands. CONCLUSIONS - Buerger’s disease is a disorder with unclear aethiology and is difficult to diagnose. Despite of a good prognosis, a causal treatment is not yet possible, so any antithrombotic, haemorheological, vasodilator or immunosuppressive therapy that have been reported to have beneficial effect should be considered for treatment.]

[The atherosclerosis can not only be prevented, but also can be cured ]

MÁRK László

[The process of atherosclerosis nowadays plays an important role in the health care not just as a major cause of the most common cardiovascular diseases which lead to death, but also as a major factor in the loss of age-related elasticity in the blood vessels. Over the past two decades, large studies have shown that the treatment of high cholesterol levels can reduce the frequency of cardiovascular events and death and have confirmed the ability to reduce the already existing atherosclerotic plaque, which is almost unique in pharmacotherapy. Using lipid lowering therapy, if we do it properly, we can not only prevent vascular events, but can also cure atherosclerosis. Currently there are three drug groups (statins, ezetimibe and PCSK9- inhibitors), which have complete evidence that their use can reduce the number of cardiovascular events and plaque regression can be achieved. Despite many convincing clinical trials, lipid-lowering therapy is on the cardiovascular prevention palette in the just tolerated or forced applied category. In order to take advantage of its potentials at an appropriate level, as doctors, we have to approach to it by considering its importance. We should communicate to our patients that it’s about a life-long treatment, which not only can reduce the possibility of cardiovascular events, but also can slow down the aging process of the arteries. ]

Hypertension and nephrology

[Sándor Gerő, the researcher clinician (1904-1992)]

GÁCS János

[Sándor Gerő presents two theories concerning the origin of atherosclerosis. The first one is called “primary lipid infiltration concept” which means the penetration of high concentration plasma lipids into the arterial wall without its damage. The other theory for the origin of atherosclerosis is primary damage of the vascular wall (namely of fibers, mucopolysaccharid etc.) which is followed by lipid infiltration. In the literature it is named “primary vascular concept” of atherosclerosis. The author investigates the two possibilities with experimental and clinical methods and concludes that primary vascular damage is more probable to be the origin of atherosclerosis.]
