[Statins for elderly people, in primary prevention?]

BAJNOK László

[In a recent, retrospective cohort study, statin usage in primary prevention was found being not beneficial for patients (i) without diabetes over 75 years of age, and (ii) with diabetes over 85 years of age (75-84 years total mortality of diabetics was also lower). These findings are in sharp contrast to the two outstanding, double-blind, placebo controlled, randomized, a primary prevention studies done with rosuvastatin. Of these, 50% reduction in LDL-C in JUPITER was associated with a 50% reduction in risk and 25% reduction in LDL-C in HOPE-3 with 25% reduction in risk. Furthermore, subgroup analyzes did not indicate lower efficacy for the elderly. The recommendation of the European Atherosclerosis Society for primary preventions of the elderlies recommending consideration of statin use in these cases (Class IIa) is particularly relevant, especially in the presence of other risk factors such as hypertension. In the primary prevention lipid treatment, we can see quite clearly till 75 years of age and hopefully, we will even further after learning about the results of STAREE, a study that is designed to elderly and in which 40 mg atorvastatin is applied.]

[The importance of anticoagulant therapy in patients with artial fibrillation in stroke prevention – summary of international data and novel therapeutic modalities]

MIROLOVICS Ágnes, PAPP Csaba, ZSUGA Judit, BERECZKI Dániel

[The most common cardiogenic cause of ischaemic stroke is atrial fibrillation which increases the probability of stroke five-fold and doubles case fatality. Based on international data the incidence of atrial fibrillation is approx. 2% however this rapidly increases with age. The necessity of using oral anticoagulants in the prevention of non-valvular atrial fibrillation related stroke is decided based on estimated stroke risk. The CHADS2 and the more predictive CHA2DS2-VASc scales are used for this purpose while the bleeding risk of patients treated with anticoagulant may be estimated by the HAS-BLED scoring scale. For decades oral anticoagulation meant using vitamin-K antagonists. Based on international data we can see that rate of anticoagulation is unacceptably low, furthermore most of the anticoagulated patients aren’t within the therapeutic range of INR (INR: 2-3). A lot of disadvantages of vitamin-K antagonists are known (e.g. food-drug interaction, need for regular coagulation monitoring, increased risk of bleeding), therefore compounds with new therapeutic target have been developed. The novel oral anticoagulants (NOAC) can be divided in two major subgroups: direct thrombin inhibitors (dabigatran etexilate) and Xa-factor inhibitors (rivaroxaban, apixaban, edoxaban). These products are administered in fix doses, they less frequently interact with other medications or food, and regular coagulation monitoring is not needed when using these drugs. Moreover several studies have shown that they are at least as effective in the prevention of ischaemic stroke than the vitamin-K antagonists, with no more haemorrhagic complications.]

[Meta-analysis about the Incontinence-associated dermatitis prevention ]

KÓSZÓ Lilla, NAGY Erika

[Background: The maintenance of tissue integrity is an essential part of qualitative nursing. There is a wide scale of products serving the prevention of Incontinence-associated Dermatitis (IAD). However, there is little evidence nurses know about them, making their choice of strategy difficult. Aim: To produce an evidence based publication about the preventive products of IAD, helping nurses in their choice of strategy. Method: In our meta analysis we examined the content of the Medline and Scopus database with special focus on English and Hungarian publications from the last ten years. From the 17459 articles relevant in this topic we analyzed and included 9 studies serving our criteria. Records: We found several methods of prevention; Washing without water, special absorbent pants, protocols and a study about the ’perineal pouch’. The studies were compared from the aspect of IAD prevalence, severity and cost effects. The 3in1 products and protokolls are should be used is the hungarian nursing practice.]

[Blood pressure management for stroke prevention and in the acute stroke. The new guideline of European Society of Hypertension (ESH, 2018), European Society of Cardiology and Hungarian Society of Hypertension (HSH, 2018)]

JENEI Zoltán

[Hypertension is the leading modifiable risk factor for stroke. Its prevalence amongst stroke patient is about 60-70% and the benefit of blood pressure (BP) lowering therapy on stroke risk reduction is well established. However the optimal BP targets for preventing stroke and reducing stroke consequences have been controversial. The new European (ESC/ESH) and Hungarian (HSH) hypertension guideline published in 2018 highlighted the primary and secondary prevention of stroke and the BP management in the acute stroke care as well. According results from ACCORD, SPRINT, HOPE-3, and other metaanalysis the systolic blood pressure (SBP) lowering < 120 mmHg has not favourable effect, thus in hypertensive patients < 65 years the SBP should be lowered to a BP range of 120-129 mmHg. In older patients ≥ 65 years the SBP should be targeted to a BP range of 130-139 mmHg (IA). In patients with acute intracerebral haemorrhage careful acute BP lowering with iv. therapy, to <180 mmHg should be considered only in case of SBP ≥ 220 mmHg (IIaB). In patients with acute ischaemic stroke who are eligible for iv. thrombolysis, BP should be carefully lowered and maintained to < 180/105 mmHg for at least the first 24 h after thrombolysis (IIaB). If the patient is not eli gible for lysis and BP ≤ 220/110 mmHg, routine BP lowering drug therapy is not recommended inside 48-72 h (IA). In patients with markedly elevated BP > 220/110 mmHg who do not receive fibrinolysis, drug therapy may be considered, based on clinical judgement, to reduce BP by 15% during the first 24 h after the stroke onset (IIbC). After 72 h of acute stroke in case of hypertensive patients < 65 years the SBP should be lowered to a BP range of 120-129 mmHg (IIaB). In older patients ≥ 65 years the SBP should be targeted to a BP range of 130-139 mmHg (IA). If BP < 140/90 mmHg after stroke, the BP lowering should be considered (IIbA). It is recommended to initiate an antihypertensive treatment with combination, preferably single pill combination of renin-angiotensin system blockers plus a calcium channel blocker and/or a thiazide like diuretics (IA). Lowering SBP < 120 mmHg is not recommended due to advers events regardless of age and type of stroke either in primary or secondary stroke prevention.]

[Prevention of polyuria during lithium treatment. Recent research and history]

[Renal toxicity of lithium is a highly important subject which may jeopardize the use of an agent needed by millions suffering from recurrent episodes of bipolar disorder. Lithium induced severe renal damage leading to end stage renal disease can be almost prevented today using lowered plasma lithium levels. But administration of medicines are necessary for the prevention of the lithium induced disturbance in renal concentrating operation and development of nephrogenic diabetes insipidus. Use of thiazides, non-steroid anti-inflammatory compounds (indomethacine) amiloride, high doses of desmopressin and their combinations are our present armamentarium. The present therapy for lithiuminduced nephrogenic diabetes insipidus in man is to counter anti-vasopressin action of lithium. The “future” treatment seems to be (on the basis of recent animal experiments) to enhance the sensitivity of the kidney to vasopressin action by administering pharmacologic blockade of the renal P2Y12 receptor by using clopidrogel or prasugrel.]

[Prevention and treatment of venous thromboembolism in cancer patients]

[Venous thromboembolism (VTE) is a common and severe complication of cancer. Deep vein thrombosis and pulmonary embolism are the second most common cause of death in cancer patients. Cancer, tumor-related factors as well as patient’s general condition and comorbidities are responsible for the increased risk of VTE. Chemotherapy is one of the most important risk factors for VTE, increasing incidence of VTE by 6.5-fold. In my paper, current guidelines for cancer VTE prevention and treatment are reviewed. Hospitalized patients with active tumor are at higher risk for VTE, and thrombosis prophylaxis is recommended in all cases. Extensive, routine prophylaxis for advanced cancer patients receiving chemotherapy is not recommended, but may be considered in high-risk ambulatory cancer patients (Khorana-score ≥ 3). Risk factors may change during the course of cancer disease, and the score should be continually reviewed and prophylactic treatment changed as necessary. LMWH is the recommended agent for both primary and secondary prophylaxis/treatment. Direct oral anticoagulants (DOACs) are knocking on our door, but results from further clinical trials are pending to determine their exact role.]

[Suicide endangering elderly people: risk factors, prevention and care]

BARACZKA Krisztina

[According to the data of the Hungarian Central Statistical Office (HCSO), the Hungarian citizens aged over 65 represented in 2001 11.8%, 2011 13.2% and 2019 19.3% of the total population. Providing services for aging (>60 years), aged (>75 years), very old (>90 years) and Matusalem (>100 years) individuals burdens heavily the health system and the socio-economic sector. Maintaining these people’s physical and mental health and self-perceived well-being is a pre-eminently important task. According to the World Health Organization (WHO) statistics based on data providing countries, the number of suicides committed in the population aged 60-79 has risen approximately by 21% between 1987 and 2006. The suicide rate in Hungary has decreased steadily and significantly since 1980 (4809 in 1980, 1656 in 2018, i.e. a decrease of 66%). Thus since 2018, Hungary is not among the top three countries in Europe and the top 15 in the world. However, the number of completed suicides and suicide attempts remains high and shows rising tendency in the elderly. Preventing suicide, exploring the risk factors and caring patients after attempted suicide we need to analyse thoroughly and disseminate widely the results of the recent researches. In this study, we re­viewed international and domestic literature data to find answers primarily to prevention issues. ]

[Prevention of drug-related neuropathy in the clinical practice]

VAJDICS Tímea

[There was a revolution of oncological treatments in the last fi ve years caused by introduction of immuncheckpoint inhibitors. Platinum and taxane based chemotherapies are the standard of care of the most frequent malignancies such as colon and breast cancer. Signifi cant improvement was achieved concerning side effects of chemotherapy in the few past decades. Preventive treatment of vomiting, neutropenia, aneamia are now based on clinical evidences. Meanwhile, there remained side effects (including chemotherapy induced neuropathy) which are diffi cult to treat. This article provides overwiev of the pharmacological therapies, vitamins and non-pharmacological procedures aimed to prevent chemotherapy induced neuropathy. Unfortunately still there are no drugs that are highly effective of preventing of chemotherapy induced periferial neuropathy validated in randomized clinical trials.]

[Recommendations of the European Atherosclerosis Society (EAS) and the European Society of Cardiology (ESC) for dyslipidaemia. Focused on: primary prevention]

BAJNOK László

[In 2019 the European Atherosclerosis So­ciety (EAS) and European Society of Car­dio­logy (ESC) renewed their dyslipidae­mia guidelines. The new version is more progressive than the previous ones. Thus, in the low-risk, not severely hy­per­choles­te­ro­lae­mic population cholesterol-lowering medication is also suggested. Except this low-risk group, atherogenic target values, e.g. for LDL-cholesterol, were reduced by an entire category, in some cases to the lowest one. If these goals cannot be achieved with statin-monotherapy, combined treatment is recommended generally by the cholesterol inhibitor ezetimib, and in some very high-risk cases also by innovative cholesterol lowering so-called PCSK9 inhibitor. ]
