[Chronic kidney disease has profound effects on the health related quality of life (HRQoL) of patients with serious physiological, psychological and socio-economic implications. The co-occurrence of protein-energy wasting (PEW) and inflammation in end stage renal disease patients is associated with worse HRQoL and increased mortality. We designed this study to examine the relationship between nutritional and inflammatory status and HRQoL in kidney transplant recipients. Data from 100 randomly selected kidney transplant patients were analyzed in a crosssectional survey. Socio-demographic parameters, laboratory results, transplantation related data, co-morbidities, medication and malnutrition-inflammation score (MIS) (Kalantar Score) were tabulated at baseline. Patients completed the Kidney Disease Quality of Life-SF (KDQoL-SFTM) self-administered questionnaire. Mean age was 51±13 years, median (interquartile range, IQR) time since transplantation 66 (83) months, 57% were males and 19% had diabetes. The median (IQR) MIS was 3 (3). MIS significantly and negatively correlated with almost all HRQoL domains analyzed, and this association remained significant in multivariate linear regression analysis for the log-transformed scores on energy/fatigue (β=-0.059, p<0.001), bodily pain (β=-0.056, p=0.004), physical functioning (β=-0.029, p=0.022), and symptoms/problems (β=-0.023, p=0.005) domains after statistical correction for age, gender, eGFR, dialysis vintage, Charlson Comorbidity Index and occupational status. Additionally, cubic spline analyses revealed linearly increasing, “dose-response” relationship between almost all domains of KDQoL-SFTM and the MIS. Malnutrition Inflammation Score is independently associated with different dimensions of health related quality of life in kidney transplant recipients.]

[Is there a role of triple combination in the therapy of hypertension? - Antihypertensive efficiency of perindopril-amlodipine-indapamide]

PÁLL Dénes, SZÁNTÓ Ildikó, PARAGH György, KATONA Éva

[Blood pressure reduction to target level decreases cardiovascular morbidity and mortality. However, in the vast majority of cases, this can be achieved only with a (multiple) combination regimen. The primary objective of the PAINT (Perindopril- Amlodipine plus Indapamide Combination for Controlled Hypertension Non-intervention Trial) study was to evaluate the efficacy of combination therapy with perindopril, amlodipine, and indapamide in patients who had not reached target blood pressure with their pre-existing therapy. Secondary objectives included the monitoring of metabolic parameters and the number of antihypertensive tablets taken by the subjects. In this subgroup-analysis we involved 126 patients (74 females and 52 males, mean age 59.8±12.5 years) who had a valid 24-hour ambulatory blood pressure monitoring both at baseline and at the end of the 4-months follow-up. At the beginning of the study none of the subjects reached blood pressure target despite taking on average 2.4±1.4 antihypertensive drugs. During the study, the subjects received the combination of amlodipine, perindopril, and indapamide instead of their pre-existing antihypertensive regimen. 24-hour mean systolic blood pressure decreased from 139.2±13.4 mmHg to 126.5±12.9 mmHg (p<0.01), as well as mean diastolic blood pressure from 77.3±11.3 mmHg to 71.1±8.7 mmHg (p<0.01). Heart rate remained unchanged. Blood pressure reduction was statistically significant both during the day and the night. We found significant blood pressure reduction in all hours (10.1-15.4/5.1-7.8 mmHg; p<0.001). Hyperbaric impact decreased from 366.9±251.1 mmHg × hour to 166.2±185.4 mmHg × hour (p<0.01) for systolic blood pressure, and from 112±130.6 mmHg × hour to 41.6±65.6 mmHg × hour (p<0.01) for diastolic blood pressure. We also could observe favourable changes in metabolic parameters, not only in lipids, but also in blood sugar level. The mean number of tablets taken by the subjects increased from 2.4 to 2.9, but this led to a significantly improved control of blood pressure. Triple combinations of state-of-the-art antihypertensive agents - such as of perindopril, amlodipine and indapamide - ensure effective blood pressure control in sufficiently compliant patients.]

[Hypertensive and cardiovascular risks of nonsteroidal antiinflammatory drugs]

FARSANG Csaba, BEDROS J. Róbert, ALFÖLDI Sándor

[Nonsteroidal antiinflammatory drugs (NSAIDs) are among the most frequently used medicines. During the last ten years several original publications, reviews and meta-analyses were published on the cardiovascular safety of NSAIDs and the results underlined their potentially harmful cardiovascular side effects. It can also be emphasized that there are substantial differences between different compounds, and the CV risk does not depend on the ratio of COX-1/COX-2 selectivity. Cardiovascular risk can be increased by all NSAIDs and paracetamol with the possible exception of naproxen and probably aceclofenac.]

[The apparatus which controls our kidney too. - Part 1]

ROSIVALL László

[The series gives a brief overview on the discovery of the juxtaglomerular apparatus (JGA), an interesting story, as well as on details of its structure and function down to the molecular level. The discovery of JGA, i.e., a phylogenetically ancient organ, is a fine example of the close morphological and functional correlations characteristic of living organisms. Presented are the JGA related misconcepts and the underlying theoretical and practical difficulties. Utilization of the most modern methods, such as atomic force microscopy, as well as the in vivo multiphoton laser microscopy revealed previously unrecognized phenomen highlighting the ambiguities of textbook information, accepted paradigms. The author is looking for relationship between the new and provocative theoretical research and clinical consequences of pharmacological interventions. He shows that JGA is not only a participant of the salt-water balance and blood pressure regulation, but it can also play a significant role in the pathogenesis of the major public diseases. Finally, he makes an attempt to analyze the current research directions that predict some potential scientific discoveries and describe some general lessons from his own research career.]

[Etiology and diagnosis of renal failure after pediatric cardiac surgery]

TÓTH Roland, CSERÉP Zsuzsanna, SZÉKELY Andrea

[Acute kidney injury is a common and severe clinical problem in children after cardiac surgery, defined by abrupt decline in renal function, with manifestations ranging from minimal elevation of serum creatinine to anuric renal failure. The condition can have a negative influence on the long-term outcome of the illness. The problem is more likely in pediatric cardiac surgery, where the low birth-weight neonates and premature infants can be even more affected. On the other hand chronic renal disease can occur as a severe consequence of acute renal failure. The standard methods to diagnose the acute renal failure in patients are henceforward good applicable, but besides these based on the latest articles of scientific journals there are a lot of new alternatives, which could help us to establish the diagnosis of renal failure more quickly and correctly. These renal specific biomarkers and proteins could predict renal failure sensitively and specifically. Although the applicability of these methods is limited yet, there are a lot of cardiac centres for children, where they are used as routine tests.]

[Estimation of serum uric acid in the Hungarian population]

KÉKES Ede, BARNA István, DAIKI Tenno, DANKOVICS Gergely, KISS István

[The clinical significance of serum uric acid markedly increased in the last years, especially in the civilized countries, but the abnormal serum uric acid level shows a significantly strong increasing tendency worldwide. The high level of uric acid is an integral part of metabolic syndrome. Today we recognized the important role of xanthine oxidase in the clinical practice for developing of oxidative stress in some tissues and organs. In 2011 during the Hungarian Health Care Screening Program we analyzed the prevalence of metabolic factors in 18 886 subjects. In the present publication we have dealt with uric acid and calculated the occurrence of abnormal values in percentage of the observed population. We found abnormal values in 12.3% of women (over 350 µmol/l) and 16.5% of men (over 400 µmol/l). The average values were higher in hypertensive subjects against normotensive ones in both gender. There was a close correlation among the metabolic components and the elevated uric acid level. The screening had given a possibility for detecting hidden gout and some other diseases, where the elevated uric acid level is specific of the clinical entity.]

KOZMANN Krisztina, JÁNOSNÉ PÁNKI Roxána, FERENCZY Mónika, KOMLÓSI Kálmánné, KARÁCSONY Ilona

[To assess sexual function, functionality and quality of life in women with cervical cancer. Descriptive, cross-sectional, quantitative, non-random, purposive sampling of women (N=91) with FIGO stage I/II/III cervical cancer, more than 5 months after last treatment. The study used standard questionnaires with self-designed questions. Data were analysed using Microsoft Excel, descriptive and mathematical statistics (p<0.05). Completers who received radiotherapy scored significantly higher in functional status (p<0.05) and emotional function than those who did not receive radiotherapy (p<0.05). Completers with lower levels of emotional well-being were significantly more likely to have lower levels of sexual function and higher levels of gynaecological problems (p<0.05). Women affected by cervical cancer often experience somatic and psychological disturbances that reflect on quality of life associated with the disease and treatment.]

RÁCZ Viktória Kinga, HEGEDŰS Bianka Ágnes , SZEBENI-KOVÁCS Gyula , FERENCZY Mónika

[The aim of this study is to assess the relationship between the physical activity of asthmatics, sleep disorders, the extent of asthma treatment, and to assess the quality of life in terms of physical activity. We conducted our quantitative, cross-sectional survey between 2020-2021. In a non-randomized, comfort sampling the target group was defined as adolescents aged between 14–18 years, their diagnosis of asthma bronchiale had to be for at least 1 year ago. The data were collected by a self-prepared questionnaire, the domains included: socio-demographic questions related to physical activites, symptoms, sleep disorders, severity of asthma. We used miniAQLQ to assess quality of life. The statistical analysis were performed by using Microsoft Excel 2016 and SPSS v 24 programs. Descriptive statistics (mean, standard deviation, minimum, maximum), two-sample t-test, Chi-square test were performed. The mean age of the respondents was 16±1.51, 38% were boys and 62% were girls (N=105). There was no significant difference between physical activity and the frequency of seizures and sleep disorders (p>0.05). There is a significant difference between the genders and the symptoms increasing with intense exercise (p=0.02). We found significant correlation between the active participations in physical education classes and the severity of the disease (p=0.021). There is a significant correlation between moderate-, social activities and physical activity (p<0.05). Appropriate health education, recommendation in career choices as well as in physical activities done by nurses may lead to decrease in the number of suffocation attacks in cases of adolescents suffering from asthma bronchiale.]

[Background and purpose - Data on the disease burden of Duchenne Muscular Dystrophy are scarce in Hungary. The aim of this study was to assess patients’ and their caregivers’ health related quality of life and healthcare utilisations. Methods - A cross sectional survey was performed as part of the European BURQOL-RD project. The EQ-5D-5L and Barthel Index questionnaires were applied, health care utilisations and patients’ informal carers were surveyed. Results - One symptomatic female carer, 50 children (boys 94%) and six adult patients (five males) participated in the study, the latter two subgroups were included in the analysis. The average age was 9.7 (SD=4.6) and 24.3 (SD=9.8) years, respectively. Median age at time of diagnosis was three years. The average EQ-5D score among children and adults was 0.198 (SD=0.417) and 0.244 (SD=0.322), respectively, the Barthel Index was 57.6 (SD=29.9) and 53.0 (SD=36.5). Score of satisfaction with healthcare (10-point Likert-scale) was mean 5.3 (SD=2.1) and 5.3 (SD=2.9). 15 children were hospitalised in the past 12 months for mean 12.9 (SD=24.5) days. Two patients received help from professional carer. 25 children (mean age 11.1, SD=4.4 years) were helped/supervisied by principal informal carer (parent) for mean 90.1 (SD=44.4) hours/week and further family members helped in 21 cases. Correlation between EQ-5D and Barthel Index was strong and significant (0.731; p<0.01) as well as with informal care time (-0.770; p<0.01), but correlation with satisfaction with health care was not significant (EQ-5D: 0.241; Barthel Index: 0.219; informal care: -0.142). Conclusion - Duchenne muscular dystrophy leads to a significant deterioration in the quality of life of patients. Parents play outstanding role in the care of affected children. This study is the first in the Central and Eastern European region that provides quality of life data in this rare disease for further health economic studies.]

[The quality of life of the cluster headache patients during the active phase of the headache]

DIÓSSY Mária, BALOGH Eszter, MAGYAR Máté, GYÜRE Tamás, CSÉPÁNY Éva, BOZSIK György, ERTSEY Csaba

[Introduction - Cluster headache (CH), which affects 0.1% of the population, is one of the most painful human conditions: despite adequate treatment, the frequent and severe headaches cause a significant burden to the patients. According to a small number of previous studies, CH has a serious negative effect on the sufferers’ quality of life (QOL). In the current study, we set out to examine the quality of life of the CH patients attending our outpatient service between 2013 and 2016, using generic and headache-specific QOL instruments. Methods - A total of 42 CH patients (16 females and 26 males; mean age: 39.1±13.5 years) completed the SF-36 generic QOL questionnaire and the headache- specific CHQQ questionnaire (Comprehensive Headache- related Quality of life Questionnaire), during the active phase of their headache. Their data were compared to those of patients suffering from chronic tension type headache (CTH) and to data obtained from controls not suffering from significant forms of headache, using Kruskal-Wallis tests. Results - During the active phase of the CH, the patients’ generic QOL was significantly worse than that of normal controls in four of the 8 domains of the SF-36 instrument. Apart from a significantly worse result in the ‘Bodily pain’ SF-36 domain, there were no significant differences between the CH patients’ and the CTH patients’ results. All the dimensions and the total score of the headache-specific CHQQ instrument showed significantly worse QOL in the CH group than in the CTH group or in the control group. Conclusion - Cluster headache has a significant negative effect on the quality of life. The decrease of QOL experienced by the patients was better reflected by the headache-specific CHQQ instrument than by the generic SF-36 instrument. ]

[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.]
