[Recommendation for the treatment of hyperlipidemia in chronic renal disease]


JUNE 20, 2010

Hypertension and nephrology - 2010;14(03)

[The incidence of chronic kidney disease continuously increases worldwide. Studies suggest that kidney disease is an as powerful cardiovascular risk factor as diabetes mellitus. Because of the high prevalence of lipid disorders, it is likely that dyslipidaemia plays a major role in the high cardiovascular risk of these patients. Evidence supports treating dyslipidaemia in patients with mild or moderate kidney disease, but the results of statin trials in dialysed patients are inconclusive. A practical treatment algorithm is proposed considering the special aspects, the effectiveness and safety of the drugs in the whole spectrum of kidney disease.]

[Sevelamer: an old-new phosphate binder in chronic kidney disease]


[Sevelamer HCl is a non-metal and non-calcium based phosphate binder, ion exchange resin, which not selectively binds the phosphate ions in the gastrointestinal tract. In Hungary since 2005, on the basis of strict professional guidelines, sevelamer is available therapy for chronic kidney disease patients with severe hyperphosphatemia on dialysis. On the basis of 17 prospective and retrospective studies, sevelamer HCl is an at least as effective phosphate binder as other calcium based binders, in reducing the serum phosphate level. The advantage of sevelamer compared to the other widely used calcium based phosphate binders is the significantly lower serum calcium level and less hypercalcemic episodes. Sevelamer therapy in chronic kidney disease patients reduces the progression of cardiovascular calcification and it has also a positive effect on cholesterol and LDL-cholesterol levels. The side effects of sevelamer therapy may be acidosis, and gastrointestinal complaints. This year the improved form, sevelamer carbonate, becomes available in Hungary. Sevelamer carbonate has similar phosphate and cholesterol binding capacity as that of sevelamer HCl, but it has several advantages: it has a positive effect on acid-base parameters, and may be administered in powder form, which is beneficial for children and for patients with swallowing disorders. The primary analysis of the DCOR study has not revealed any significant difference in the survival and cardiovascular mortality between patient groups treated with calcium based binder or sevelamer. The RIND trial data showed improved survival of new dialysis patients, who were initially treated with sevelamer. Further clinical studies are needed to kaverify the benefits of sevelamer therapy (mortality, cardiovascular calcification) in chronic kidney disease patients. The management of hyperphosphatemia in chronic renal failure is a major challenge even in the first decade of the 21th century. This is the fact, despite that recently three different groups of phosphate binders are available in the clinical practice: the calcium based binders (calcium carbonate, calcium acetate), sevelamer and lanthanum. Which is the best binder? A calcium based or a non-calcium based one? Over the past decade, these issues are in the mainstream of clinical research of nephrology.]

[Cardiovascular prevention in hypertensive patients - use an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker?]

BARNA István

[The primary aim of cardiovascular prevention is to reach adequate blood pressure control. To prevent the development of target organ lesion it is essential to use long-acting, well tolerable drugs without significant side effects. Angiotensin-converting enzyme (ACE) inhibitors are popular and excellent preparations but their side effects reduce life long patient compliance. Angiotensin II receptor blockers (ARBs) are effective drugs having unique tolerability and a capability to reduce cardiovascular morbidity and mortality to the same extent as the ACE inhibitors. Especially high risk patients benefit from their combination with thiazide diuretics or with calcium channel blockers. Clinical trials proved that telmisartan can be safely given and well tolerable alone or in combination to high risk cardiovascular patients, in heart and renal, peripheral vascular and cerebrovascular diseases combined or not with diabetes.]

[The significance of depressive disorders in patients with chronic kidney diseases]

ZALAI Dóra Márta, SZEIFERT Lilla, NOVÁK Márta

[In this article a practice-oriented narrative review of the depressive disorders in chronic kidney disease is provided. Depressive disorders affect approximately one fourth of the chronic kidney disease population. These mental disorders interfere with physical, cognitive and social functioning and are associated with poor prognosis of patients with chronic kidney disease. Bio-psycho-social factors, including immuno-inflammatory processes, disturbance in glucose- insulin homeostasis, sleep disorders, chronic pain, sexual difficulties, changes in social roles, losses in multiple areas of life and low social support increase the risk for the development of depression. Routine, regular screening of depression in the chronic kidney disease population seems to be warranted. Only limited published evidence is available on the therapeutic possibilities of depression in chronic kidney disease. Preliminary evidence indicates that short, structured psychotherapy may be effective for acute treatment and prevention of psychological distress. Some antidepressants can be applied without the need for dose adjustments. On the other hand, some of the psychotropic medications require dose reduction or should be avoided.]

[Recognition of subclinical atherosclerosis: new results of the ÉRV Programme and the ÉRV Registry]

FARKAS Katalin, KOLOSSVÁRY Endre, JÁRAI Zoltán, KISS István

[In the ÉRV Programme of the Hungarian Society of Hypertension hypertensive patients were screened for the presence of peripheral arterial disease (PAD). Ankle/brachial index (ABI) and major cardiovascular risk factors were recorded before the five years long prospective phase of the program. A total of 21 892 hypertensive men and women (9162 males; mean age: 61.45 years) who were attended at 55 hypertension outpatient clinics in Hungary during a 17 month period, were included in the study. The prevalence of PAD defined by low ABI (≤0.9) was 14.0%. In the two blood pressure target groups (140/90 mmHg and 130/80 mmHg) the ratio of patients with controlled blood pressure was 45% and 33%, respectively. The prevalence of PAD (ABI≤0.9) was 10.9% in the controlled and 16.1% in the uncontrolled group (p<0.0001). During the control visits a significant decrease of blood pressure was observed. ÉRV Registry was initiated for ABI screening in subjects at risk for PAD in the general practice. The prevalence of PAD was 18.3%. The prevalence of PAD (low ABI value) is high in hypertensive patients. Uncontrolled hypertension increases the risk of PAD. The results indicate, that ABI screening is a simple and cost-effective method for the diagnosis of preclinical atherosclerosis, which may improve cardiovascular risk prediction.]

[Changes in endothelial cells caused by cigarette smoke]

WAGNER László, LACZY Boglárka, CSEH Judit, TAMASKÓ Mónika, MAZÁK István, MARKÓ Lajos, MOLNÁR Gergő Attila, WAGNER Zoltán, MOHÁS Márton, FEKETE Andrea, WITTMANN István

[Endothelial nitric oxide synthase enzyme is regulated through the phosphorylation of the Ser(1177) and the Thr(495) sites, which influence the biological availabilaty of nitric oxide. We examined the acute effect of cigarette smoke, which decreases nitric oxide production. Endothelial cells were treated with different concentrations and for different times with cigarette smoke buffer, then with reduced glutathione or different protein kinase inhibitors. We determined the total and the phosphorylated nitric oxide synthase levels with Western blot. Cigarette smoke increased phosphorylation in a concentration- and time dependent manner at the Ser(1177) site and more pronounced at the Thr(495) site. Besides, it also led to the dissociation of the active dimer form of the enzyme. Reduced glutathione inhibited these phosphorylations and prevented the dissociation of endothelial nitric oxide synthase enzyme. The inhibition of protein kinase A or B did not influence the effect of cigarette smoke. However, protein kinase C inhibitors increased the phosphorylation caused by cigarette smoke at Ser(1177), but decreased it at Thr(495) sites. Summarized, cigarette smoke shifts the phosphorylation of the enzyme towards an inhibitory state, further on, it leads to the dissociation of the enzymatically active form. This results in the decreased biological availabilaty of nitric oxide, in which protein kinase C may play an important role.]

[Benefits of SGLT-2 inhibitors: beyond glycemic control]

BALOGH Zoltán, SIRA Lívia

[In the recent years, according to international and Hungarian guidelines, in addition to lifestyle modification, metformin is the preferred initial glucose-lowering drug for most people with type 2 diabetes, if not contraindicated. Sodium glucose co­transporter-2 inhibitors have been shown to reduce progression of chronic kidney disease, or kidney failure, as well as the risk of hospitalizations for congestive heart failure and (mainly in secondary prevention) cardiovascular death in patients with type 2 diabetes. For major adverse cardiovascular events and for the renoprotection, there seems to be no class effect. On the other hand, a class effect of sodium glucose co­transporter-2 inhibitors is evident for hospitalization for heart failure. In this review the authors summarize novel data about sodium glucose cotransporter-2 inhibitors, and about their new perspectives in the near future.]

[Guidelines for the treatment of traumatic brain injury - 2017]

BÜKI András, BARZÓ Pál, DEMETER Béla, KANIZSAI Péter, EZER Erzsébet, TÓTH Péter, HORVÁTH Péter, VARGA Csaba

[Traumatic brain injury (TBI) is recognized to be the main cause of death and disability in the first four decades representing a major socio-economical problem worldwide. Recent communications revealed a particularly worrying image about the quality of care for TBI in Hungary. For any improvement a systematic approach characterized by utilization of scientific evidence based guidelines forming the basis for close monitoring of the actual care are considered a prerequisite. In Hungary the first evidence based guidelines in the field of TBI have been issued by the National Society for Anesthesiology and Intensive Care more than two decades ago followed by joint guidelines of the Hungarian Neurosurgical Society and the Hungarian College of Neurosurgeons. These publications were primarily based on the work of the European Brain Injury Consortium as well as guidelines issued by the Brain Trauma Foundation. Recent renewal of the latter and a need to refresh the outdated national guidelines was met by a call from regulatory authorities to issue the updated version of the Hungarian TBI-guidelines. The present review is aimed to briefly summarize the most fundamental elements of the national head injury guidelines that would hopefully be officially issued in a far more detailed format soon.]

[Pharmacological and nonpharmacological treatment of insomnias with regard to sleep medicine]


[Insomnia - one of the most prevalent sleep complain - has a great impact on the everyday life. Basically two different form of insomnia can be defined: the insomnia disorder and the co-morbid insomnias. To treat adequately determination of background pathology is essential, which is based on the help of Sleep Medicine Centers. According to the newest guidelines, the treatment of insomnia disorder is based on cognitive behavioural therapies followed by pharmaceutical intervention. In this review we provide the short description of cognitive behavioural therapies and basic principles of hypnotic drugs. Despite the availability of insomnia guidelines the huge variation of the insomnia medication can be seen in the daily practice. Due to the above mentioned reasons we summarize the good clinical practice of hypnotic drug administration for insomnia patients.]

Risk factors for ischemic stroke and stroke subtypes in patients with chronic kidney disease

GÜLER Siber, NAKUS Engin, UTKU Ufuk

Background - The aim of this study was to compare ischemic stroke subtypes with the effects of risk factors, the relationship between grades of kidney disease and the severity of stroke subtypes. Methods - The current study was designed retrospectively and performed with data of patients who were hospitalised due to ischemic stroke. We included 198 subjects who were diagnosed with ischemic stroke of Grade 3 and above with chronic kidney disease. Results - In our study were reported advanced age, coronary artery disease, moderate kidney disease as the most frequent risk factors for cardioembolic etiology. Hypertension, hyperlipidemia, smoking and alcohol consumption were the most frequent risk factors for large-artery disease. Female sex and anaemia were the most frequent risk factors for small-vessel disease. Dialysis and severe kidney disease were the most frequent risk factors in unknown etiologies, while male sex, diabetes mellitus, prior stroke and mild kidney disease were the most frequent risk factors for other etiologies. National Institute of Health Stroke Scale (NIHSS) scores were lower for small-vessel disease compared with other etiologies. This relation was statistically significant (p=0.002). Conclusion - In order to improve the prognosis in ischemic stroke with chronic kidney disease, the risk factors have to be recognised and the treatment options must be modified according to those risk factors.

[Case report of supine hypertension and extreme reverse dipping phenomenon decades after kidney transplantation]

BATTA Dóra, KŐRÖSI Zita Beáta, NEMCSIK János

[Supine hypertension, a consequence of autonomic neuropathy, is a rarely recognized pathological condition. Reported diseases in the background are pure autonomic failure, multiple system atrophy, Parkinson’s disease, diabetes and different autoimmune disorders. In our case report we present a case of supine hypertension which developed in a patient decades after kidney transplantation. The patient was followed for 25 months and we demonstrate the effect of the modification of antihypertensive medications. At the time of the diagnosis supine hypertension appeared immediately after laying down (office sitting blood pressure (BP): 143/101 mmHg; office supine BP: 171/113 mmHg) and on ambulatory blood pressure monitoring (ABPM) extreme reverse dipping was registered (daytime BP: 130/86 mmHg, nighttime BP: 175/114 mmHg). After the modification of the antihypertensive medications in multiple times, both office supine BP (office sitting BP: 127/92 mmHg; office supine BP: 138/100 mmHg) and on ABPM nighttime BP improved markedly (daytime BP: 135/92 mmHg, nighttime BP: 134/90 mmHg). In conclusions, our case report points out that autonomic neuropathy-caused supine hypertension and extreme reverse dipping can develop in chronic kidney disease, after kidney transplantation. The modification of the antihypertensive medications can slowly restore this pathological condition.]
