[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]

VÁLYI Péter

[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]

[Sexual problems in CKD – a narrative review]

TÖRÖK Marietta, JÖRGEN Hegbrant, GIOVANNI Strippoli

[Sexual dysfunction is highly prevalent in patients with CKD, especially those receiving dialysis. Given the high prevalence of sexual problems in CKD patients, there has been growing interest in finding effective treatments for sexual dysfunction. PDE5i and zinc have been found promising interventions for treating sexual dysfunction in men with CKD in a systematic review of RCTs, but the evidence supporting their routine use in CKD patients is limited. In the Collaborative Depression and Sexual Dysfunction (CDS) Study, over a cohort of 1611 men in hemodialysis, 83% reported erectile dysfunction and 47% reported severe erectile dysfunction, with depression strongly correlated to this problem. Similarly, sexual dysfunction was highly prevalent in women undergoing hemodialysis. Of the 659 respondents, 555 (84%) reported sexual dysfunction and more than half of sexually active women reported sexual dysfunction, associated with age, depressive symptoms, menopause, low serum albumin, and diuretic therapy.]

[Differential diagnosis and treatment of hyponatraemia]

NÉMETH Zsófia, DEÁK György

[Hyponatraemia (serum sodium concentration < 136 mmol/l) is the most frequent electrolyte abnormality that inceases the risk of both in-hospital, and outpatient mortality. Antidiuretic hormone action or low glomerular fitration rate or low excretable osmoles or their combination are involved in its pathogenesis. Differential diagnosis is based on medical and medication histories, serum- and urine osmolality and urine sodium concentration. Measurement of fractional excretions of urea and uric acid help identifying low effective circulting volume, renal hypoperfusion. Symptomatic hyponatraemia or an acute decrease of serum sodium concentration exceeding 10 mmol/l should be treated with 3% NaCl to avoid impending threat to life. The principles of the treatment of chronic hyponatraemia are restriction of water intake and elimination of etiologic factor(s) (eg. medications - most often thiazides). In case of contracted axtracellular volume, isotonic saline should be given. In case of euvolaemia, restriciton of water intake is fundamental. In case of expanded extracellular volume, (heart failure, liver cirrhosis, nephrosis), water and NaCl intake should be restricted along with aldosteron antagonist and loop diuretic therapy. In chronic hyponatraemia, the rise of serum sodium concentration should not exceed 10 mmol/l during the first 24 hours and 8 mmol/l/day thereafter. ]

[Results of ATTENTION study]

LÉGRÁDY Péter, ÁBRAHÁM György

[In the ATTENTION (Using of ARB and sTaTin basEd iNdividualized Treatments in Hungarian patients In the light Of New CV prevention guidelines) trial’s ARB arm 9996 treated hypertensive patients were enrolled. Based on the results in the medical practice, the choice of the first ARB has a significant impact on the further antihypertensive therapy. Losartan, telmisartan and valsartan are all suitable for reaching the goal blood pressure. If necessary, doctors will not change the composition but the dose or use a diuretic supplement (resistant hypertension, older age etc.). Overall a telmisartan preference was observed in the study.]

[Our clinical practice with perindopril/indapamide/amlodipine triple fixed-dose combination]

BATTYÁNYI Bertalan

[Notwithstanding the abundance of pharmacotherapeutic options available, the rate of optimal blood pressure control may be estimated as low as 20 to 40 per cent throughout Europe. The underlying causes of this include, among others, the substantial impact of using free combinations of several antihypertensive - this practice results in rather poor patient adherence. Fixed-dose dual combinations have been introduced just about two decades ago, and their popularity has been increasing progressively since then. Nevertheless, in a considerable proportion (>30%) of patients, achieving optimal blood pressure control requires treatment with at least three antihypertensive acting on different targets. Accordingly, a rational demand has grown for triple-fixed combinations. In Hungary, the fixed combination of perindopril (an ACEI), indapamide (a thiazide-like diuretic), and amlodipine (a calcium channel-blocker) has been available since last year. Our experience with this product shows, as confirmed by ABPM studies, that its routine use in hypertensive patients with cardiological comorbidities improves patient compliance, thereby enhancing also long-term blood pressure control.]

[A new, effective tool in the treatment of hypertension in light of the available evidence]

MASSZI Gabrilella

[Hypertension is important even in the group of common diseases. Cardiovascular mortality could be significantly reduced if high blood pressure could not only be treated, but controlled as well. The newly introduced fixed combination perindopril-amlodipin-indapamide medication could be a good tool for genereal practitioners, specialists in internal medicine and cardiologists. Combined treatment with the ACE inhibitor perindopril, the new vasorelaxant type diuretic indapamide and the third generation type Ca-chanel blocker amlodipin is effective in reducing blood pressure. Besides effectivity the organ protective pleiotrop qualities (cardioprotective, plakk stabilising, antiatherosclerotic, antithrombotic, stroke preventive, endothel dysfunction reducing, renal protetcion granting) provide a long lasting beneficial impact on life expectancy and a better quality of life to the patients. If we choose the right dosage, we could raise the compliance level of patients resulting in excellent degrees of compliance. In our article we wanted to draw attention to the major evidencies which are the best acknowledgements of this triple combination although we didn’t explore all avenues.]

[Initiation of antihipertensive therapy with fix combinations, focusing on perindopril, amlodipine and indapamide]

FARSANG Csaba

[Early clinical studies proved that most hypertensive patients (>70%) need drug combinations to reach the target blood pressure. We should combine two or three - sometimes more - drugs from different antihypertensive classes for quicker normalisation of blood pressure and to reduce incidence and severity of hypertensive complications. Several international and Hungarian (MHT 2015) guidelines emphasize the advantages of fix combinations against free combinations. Most frequently used combinations contain ACEi + calcium antagonist, or ACEi + diuretic. From them I will focus on the perindopril + amlodipine or perindopril + indapamide combinations. If we do not reach target blood pressure, triple fix combinations (e.g. perindopril + amlodipine + indapamide) can also be used. Now there are fix combinations of different strengths, therefore we may start the therapy with these fix combinations according to patients’ characteristics (e.g. age, complications, concomitant diseases).]

[Changes in prescribing practice of diuretics in the treatment of hypertension between 2007 and 2013 in the mirror of insurance data]

BARNA István, GYURCSÁNYI András

[Amongst diuretics, thiazides are the most commonly used antihypertensive agents. Due to their long-term effect, they are ideal for treatment of hypertension. Indapamide is a long-acting (half-life 14-16 hours) thiazide-like diuretic, which is effective in very small doses (1.25 to 5 mg). Indapamide mainly provides a forceful blood pressure lowering effect, by decreasing arteriolar and peripheral resistance due to its vasodilatative effect. Even in hypertensive, diabetic patients, indapamide does not affect the lipid metabolism or the carbohydrate metabolism. As an antihypertensive medicine, thiazide-type diuretics (only in small doses - 6.25- 12.5 mg hypothiazide, 12.5 mg chlorthalidone, 5 mg clopamide) can be the first choice, when dealing with essential hypertension disease without complications. They may also be used in monotherapy. When dealing with hypertension associated with old age or with isolated systolic hypertension, these products are recommended with “A” type evidence. For the treatment of left ventricular hypertrophy and post-stroke conditions associated with the treatment of hypertension, it is recommended to use indapamide in case of diabetes, furosemide and thiazide in case of a left ventricular dysfunction and heart failure, or a combination of these. When reviewing the national sales of mono-component diuretics between 2007 and 2013 in the National Health Insurance (OEP) database, we could see that the sales of hydrochlorothiazide, clopamide, and chlorthalidone decreased. In 2013 however, the sales of the latter experienced a turnover, which might indicate the activity of the followers of the new guideline. The use of diuretics with indapamide as their active substance increased. The prescription of diuretics used in a combination increased continuously between 2007 and 2010 and reached a monthly one million prescribed boxes. During the time in question, the use of products combined with hydrochlorothiazide (most products contain this agent) was the most dominant, but its share fell from 88% to 66% due to the growth of combinations containing the active ingredient indapamide. This is interesting because this combination is “unique” (perindopril + indapamide). During the period in question, only the prescription of this combination increased steadily. The use of diuretics is very important in antihypertensive therapy. If we compare the diuretics and their combinations to the recommendations, we can state that the treatment is done along the guidelines, or in other words the use of the metabolic neutral combination therapy is increasing.]

[Causes of and therapeutic opportunities in resistant hypertension]

SIMONYI Gábor, GENCSI Kristína

[Hypertension is an independent cardiovascular risk factor and one of the most frequent diseases in Hungary. In the treatment of hypertensive patients usually more than two drugs are needed for the appropriate blood pressure control. Resistant hypertension (RH) is defined when blood pressure remains above target value despite full doses of antihypertensive medications, which consist of at least three different classes of drugs including a diuretic administered in maximal doses. The frequency of RH can reach 20-30% among hypertensive patients. RH increases the cardiovascular risk because of the lack of target blood pressure. RH is multifactorial and it is important to exclude pseudo-resistant hypertension (e.g. poor compliance, white coat effect). In the background of RH we can find lifestyle factors (e.g. obesity, excessive salt intake, alcoholism, etc.) and a variety of drugs (e.g. non-steroids, corticosteroids, sympathomimetics). In the pathogenesis of RH the increased activity of the sympathetic nervous system has an important role. In the treatment of RH we should manage lifestyle factors and it is important to assess the drugs and diseases (e.g. sleep apnea, chronic kidney disease, diabetes mellitus) which may cause increased blood pressure. It is no exact recommendations for the treatment of RH. Therapy often consists of 4-5 various drugs in combination. An important role has the device therapy of RH in recent years (e.g. stimulation of the carotid baroreceptors and renal denervation) as well.]

[The history of diuretic treatment in Hungary. Part I. Imre Fodor]

RADÓ János

[The diuretic effect of mercurial compounds was discovered in 1920. However, the term of “mercurial diuresis” was created 36 years earlier by Ernő Jendrassik. Imre Fodor published his experiences with the mercurial diuretic, which has been cited by several authors worldwide. The Hungarian pharmaceutical industry also took its part from the production of the mercurial diuretic with Novurit that proved to be an excellent and worldwide well known preparation in the next 40 years. Even Imre Fodor required the repeated administration of mercurial diuresis because of his severe cardiac oedema in the last period of his life. When the drug became ineffective, i.e. developed refractory oedema, he made a “self-experiment” with the administration of ACTH to restore the sensitiveness to the mercurial diuretic on the basis of most recent American literature at that time. His experience has been published by his colleagues just before his death. Imre Fodor was an eminent clinician, a school creating internist who entered his name into the science dealing with the use of diuretics.]
