[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.]

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

MÁTYUS János, PARAGH György

[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.]

[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.]

[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.]

Evaluation of anxiety, depression and marital relationships in patients with migraine

DEMIR Fıgen Ulku, BOZKURT Oya

Aim - The aim of this study was to evaluate the frequency and characteristics of attacks in patients with migraine, to determine the effects of anxiety or depressive symptoms, and to evaluate the marital relationships of patients with migraine. Method - Thirty patients who were admitted to the neurology outpatient clinic of our hospital between July 2018 and October 2018 and were diagnosed with migraine according to the 2013 International Headache Society (IHS) diagnostic criteria were included in this cross-sectional study. Age, sex, headache frequency and severity, depressive traits, marital satisfaction and anxiety status were examined. We used the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Maudsley Marital Questionnaire (MMQ) and Visual Analogue Scale (VAS) for measuring relevant parameters. Results - The mean severity of migraine pain according to VAS scale was 6.93 ± 1.41 and the mean number of migraine attacks was 4.50 ± 4.24. The mean BDI score of the patients was 12.66 ± 8.98, the mean MMQ-M score was 19.80 ± 12.52, the mean MMQ-S score was 13.20 ± 9.53, the mean STAI-state score was 39.93 ± 10.87 and the mean STAI-trait score was 45.73 ± 8.96. No significant correlation was found between age, number of migraine attacks, migraine duration, migraine headache intensity, and BDI, STAI and MMQ scores (p>0.05). But there was a positive correlation between MMQ-S and scores obtained from the BDI and STAI-state scales (p<0.05). Conclusion - In this study more than half of the migraine patients had mild, moderate or severe depression. A positive correlation was found between sexual dissatisfaction and scale scores of depression and anxiety.

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.

[Disturbances of bone and mineral metabolism are frequent complications of chronic kidney disease. In the last decades, increasing evidence of both pathophysiological and epidemiological nature support the relationship between bone disease and soft tissue calcification. In this current research, we analysed characteristics, determining factors and relationship of these two complications in a nationwide, cross-sectional cohort of dialysed patients. We collected demographical data (age, gender, body weight, height, diabetes, type of dialysis), laboratory results (serum parathormone, calcium, phosphat, albumin levels) and the presence of diabetes mellitus, bone abnormalities and soft-tissue calcification in patients on maintenance dialysis in 2010. The prevalence of bone abnormalities and soft tissue calcification followed similar pattern: both prevalences were high when parathormone <150 pg/ml (42.9% and 51.5%, respectively) or >500 pg/ml (44.2% and 55.5%) and they were significantly lower when parathormone was between 150-500 pg/ml (30.7% and 47.4%). In a multivariate logistic regression model, independent predictors of bone abnormalities were low (<150 pg/ml) and high (>500 pg/ml) parathormone levels (p<0.001), orhemodialysis (vs peritoneal dialysis) (p<0.001), age (p<0.001) and diabetes (p<0.001). In a similar statistical model, predictors of soft tissue calcification were also low (<65 pg/ml) (p<0.01) and high (>500 pg/ml) parathormone levels (p<0.001), hemodialysis (p<0.001), age (p<0.001), diabetes (p<0.001) and serum calcium level greater than 2.4 mmol/l (p<0.05). In summary, there was a U-shaped relationship between increasing serum parathormone levels and prevalence of bone abnormalities and soft tissue calcification in ESRD patients on maintenance dialysis. Further research and long term follow up are needed in order to reveal more detailed relationship among the two diseases and their determining factors.]

[Physical training in dialysis population]

SCHNEIDER Károly

[The impaired physical activity and the related increased cardiovascular risk is caracteristic in all stages of chronic kidney diseases. The regular physical activity has a beneficial effect on the metabolic risks associated with chronic kidney disease, dialysis and poor activity lifestyle, it also has favorable effect on the inflammatory state, poor physical performance, muscle loss and can improve the quality of life and life expectancy. Accordingly, the international and Hungarian guidelines suggest at least 150 minutes physical activity with moderate intensity per week - at least five days, 30 minutes each day. But there are no particular guidelines for dialysated patients. This article, without being exhaustive, in part using our own experiences, present suggestions for the physical activity of dialysated patients.]

[Terciary hyperparathyreosis or not? ? You cannot solve it alone: combined treatment in severe osteitis fibrosa cystica]

HERSZÉNYI Eszter, PATÓ Éva, SZALAY László, BÍRÓ Zsolt, György Andrea, DEÁK György

[Phosphate retention, consequential rise of the phosphaturic fibroblast growth factor-23 that decreases the level of calcitriol resulting in hypocalcemia facilitates the development of secondary hyperparathyroidism (sHPT) in chronic kidney disease (CKD). Hyperphosphatemia, hypocalcemia and low calcitriol level result in increasing secretion of parathormone (PTH). While sHPT occures frequently in CKD, the development of therapy-resistant and hypercalcemic tertiary hyperparathyroidism is rare due to current therapeutic approaches. We present the case of a 41 year old, treated schizophrenic, hemodialized male patient with severe osteitis fibrosa cystica, severe hyperparathyroidism (PTH 2500 pg/ml) - considered to be tertiary - and with repeated pathologic fractures. While hospitalized, the patient was under supervised, combined therapy with the vitamin D receptor activator paricalcitol and the calcimimetic cinacalcet that resulted in marked decrease of PTH level to 1589 pg/ml. However, after discharge from the hospital due to the lack of compliance he failed to take his medications and PTH had risen to the initial level. This case demonstrates that severe hyperparathyroidism thought to be therapy resistant responds well to a combination of paricalcitol and cinacalcet however, patient compliance is essential to therapeutic success.]
