Decreased level of serum NT-proCNP associates with disease severity in COVID-19.

BACKGROUND: C-type natriuretic peptide (CNP) is an endothelium-derived paracrine molecule with an important role in vascular homeostasis. In septic patients, the serum level of the amino-terminal propeptide of CNP (NT-proCNP) shows a strong positive correlation with inflammatory biomarkers and, if elevated, correlates with disease severity and indicates a poor outcome. It is not yet known whether NT-proCNP also correlates with the clinical outcome of patients suffering from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. In the current study, we aimed to determine possible changes in the NT-proCNP levels of patients with coronavirus disease 2019 (COVID-19), with special regard to disease severity and outcome. METHODS: In this retrospective analysis, we determined the serum level of NT-proCNP in hospitalized patients with symptoms of upper respiratory tract infection, using their blood samples taken on admission, stored in a biobank. The NT-proCNP levels of 32 SARS-CoV-2 positive and 35 SARS-CoV-2 negative patients were measured to investigate possible correlation with disease outcome. SARS-CoV-2 positive patients were then divided into two groups based on their need for intensive care unit treatment (severe and mild COVID-19). RESULTS: The NT-proCNP was significantly different in the study groups (e.g. severe and mild COVID-19 and non-COVID-19 patients), but showed inverse changes compared to previous observations in septic patients: lowest levels were detected in critically ill COVID-19 patients, while highest levels in the non-COVID-19 group. A low level of NT-proCNP on admission was significantly associated with severe disease outcome. CONCLUSIONS: Low-level NT-proCNP on hospital admission is associated with a severe COVID-19 disease course. The pathomechanism underlying this observation remains to be elucidated, while future studies in larger patient cohorts are necessary to confirm these observations and reveal therapeutic importance.

Association Between Alcohol Consumption and Cardiovascular Risk Based on Data from the Three Generations for Health Program in Hungary.

BACKGROUND Alcohol consumption has a significant effect on cardiovascular health, and risk factors, such as excessive alcohol use, should be avoided. Although alcohol consumption has decreased over the last decade in Hungary, it is still significantly higher than the average across the European Union. The objective of this study was to describe the patterns of alcohol use based on the Alcohol Use Disorders Identification Test (AUDIT), with a special focus on cardiovascular risk status (low, moderate, high, or very high). MATERIAL AND METHODS The Three Generations for Health program focuses on the development of primary health care in Hungary. One of the key elements of the program is the identification of risk factors of cardiovascular diseases. An ordinal multiple logistic regression analysis was performed with 10 categorical explanatory variables and the outcome was the categorical cardiovascular risk. RESULTS The database consisted of patients aged 40-65 years with a sample size of 11 348. A significant relationship was found between alcohol consumption and cardiovascular risk status; people with high-risk drinking patterns had higher a value of odds ratio (OR=1.306 [1.003-1.701]) for having a more serious cardiovascular status. According to multiple regression analysis, alcohol dependence was associated with cardiovascular risk. CONCLUSIONS From a public health perspective, the results highlight the importance of reducing alcohol consumption with the help of primary care and preventive services in countries with a high cardiovascular risk profile to reduce the cardiovascular disease-related burden.

Metabolic syndrome and periodontitis among adults: The 2018 Indonesia National Health Survey.

AIM: This study aimed to examine the association between metabolic syndrome (MetS), its components, and periodontitis among Indonesian adults. MATERIALS AND METHODS: Cross-sectional data from the 2018 Indonesia National Health Survey (Riskesdas) was analysed. The sample included dentate individuals aged 35 years or older for whom complete information was available on components of MetS and periodontitis, including bleeding on probing (BOP) (N = 13,356), pocket depth (PD) (N = 13,273), and clinical attachment loss (CAL) (N = 13,000). Rate ratios (RRs) and 95% confidence intervals (CIs) were estimated with negative binomial regression models. RESULTS: The prevalence of MetS was 41.0%. The prevalence of individuals having at least one tooth with BOP, one tooth with PD ≥4 mm, or one sextant with CAL ≥4 mm was 74.9%, 40.7%, and 40.6%, respectively. No associations were observed between MetS and BOP, PD, or CAL, but hyperglycaemia was constantly positively associated with BOP (RR = 1.06; 95% CI 1.01-1.11), PD (RR = 1.13; 95% CI 1.03-1.23), and CAL (RR = 1.15; 95% CI 1.08-1.23). CONCLUSIONS: Our findings support the potential influence of hyperglycaemia on periodontitis. Incorporating oral disease prevention strategies into the management of systemic diseases could be beneficial for reducing the burden of these diseases in Indonesia.

Altered irisin/BDNF axis parallels excessive daytime sleepiness in obstructive sleep apnea patients.

STUDY OBJECTIVES: Obstructive sleep apnea hypopnea syndrome (OSAHS) is a sleep-related breathing disorder, characterized by excessive daytime sleepiness (EDS), paralleled by intermittent collapse of the upper airway. EDS may be the symptom of OSAHS per se but may also be due to the alteration of central circadian regulation. Irisin is a putative myokine and has been shown to induce BDNF expression in several sites of the brain. BDNF is a key factor regulating photic entrainment and consequent circadian alignment and adaptation to the environment. Therefore, we hypothesized that EDS accompanying OSAHS is reflected by alteration of irisin/BDNF axis. METHODS: Case history, routine laboratory parameters, serum irisin and BDNF levels, polysomnographic measures and Epworth Sleepiness Scale questionnaire (ESS) were performed in a cohort of OSAHS patients (n = 69). Simple and then multiple linear regression was used to evaluate data. RESULTS: We found that EDS reflected by the ESS is associated with higher serum irisin and BDNF levels; ß: 1.53; CI: 0.35, 6.15; p = 0.012 and ß: 0.014; CI: 0.0.005, 0.023; p = 0.02, respectively. Furthermore, influence of irisin and BDNF was significant even if the model accounted for their interaction (p = 0.006 for the terms serum irisin, serum BDNF and their interaction). Furthermore, a concentration-dependent effect of both serum irisin and BDNF was evidenced with respect to their influence on the ESS. CONCLUSIONS: These results suggest that the irisin-BDNF axis influences subjective daytime sleepiness in OSAS patients reflected by the ESS. These results further imply the possible disruption of the circadian regulation in OSAHS. Future interventional studies are needed to confirm this observation.

The Effect of Passive Movement for Paretic Ankle-Foot and Brain Activity in Post-Stroke Patients.

BACKGROUND: This study aims at investigating the short-term efficacy of the continuous passive motion (CPM) device developed for the therapy of ankle-foot paresis and to investigate by fMRI the blood oxygen level-dependent responses (BOLD) during ankle passive movement (PM). METHODS: Sixty-four stroke patients were investigated. Patients were assigned into 2 groups: 49 patients received both 15 min manual and 30 min device therapy (M + D), while the other group (n = 15) received only 15 min manual therapy (M). A third group of stroke patients (n = 12) was investigated by fMRI before and immediately after 30 min CPM device therapy. There was no direct relation between the fMRI group and the other 2 groups. All subjects were assessed using the Modified Ashworth Scale (MAS) and a goniometer. RESULTS: Mean MAS decreased, the ankle's mean plantar flexion and dorsiflexion passive range of motion (PROM) increased and the equinovalgus improved significantly in the M + D group. In the fMRI group, the PM of the paretic ankle increased BOLD responses; this was observed in the contralateral pre- and postcentral gyrus, superior temporal gyrus, central opercular cortex, and in the ipsilateral postcentral gyrus, frontal operculum cortex and cerebellum. CONCLUSION: Manual therapy with CPM device therapy improved the ankle PROM, equinovalgus and severity of spasticity. The ankle PM increased ipsi- and contralateral cortical activation.

Prestroke alcohol consumption and smoking are not associated with stroke severity, disability at discharge, and case fatality.

BACKGROUND: Heavy alcohol consumption and smoking are known risk factors for stroke, but their influence on stroke severity and outcome may also be important. We tested if alcohol consumption and smoking relate to initial stroke severity, disability at discharge from hospital, and outcome at 30 days and at 1 year in 1049 patients of the Mures-Uzhgorod-Debrecen database. METHODS: Initial stroke severity was scored by the National Institutes of Health Stroke Scale. Case fatality and the modified outcome scale of the First International Stroke Trial were used to assess outcome. We used multiple regression analysis. RESULTS: Before their stroke, 24.5% were smokers and 24.7% admitted regular alcohol consumption. Neither smoking nor alcohol consumption status was associated with initial stroke severity. Case fatalities at discharge, at 30 days, and at 1 year were 12.2%, 16.9%, and 28.3%, respectively. Initial stroke severity, hemorrhagic subtype, and age in men over 60 years were strong predictors of outcome. We did not find significant difference among alcohol consumers and nonconsumers in 30-day and in 1-year case fatality in all stroke patients and in ischemic stroke patients. In hemorrhagic stroke, there was a nonsignificant tendency for higher case fatality among alcohol consumers (39.5% versus 26.4%, P > .2, at 30 days and 48.8% versus 35.8%, P > .2, at 1 year). Smoking did not influence significantly the outcome at 30 days and at 1 year. CONCLUSION: Despite being risk factors, prestroke smoking and alcohol consumption do not have a significant influence on stroke severity and on short- and long-term outcome.

Relevance of Proteinuria in Kidney Transplant Recipients and Allograft Outcomes.

BACKGROUND: The onset of proteinuria in renal allograft recipients is frequently associated with an increased risk for both graft failure and mortality. We investigated the risk associated with post-transplant proteinuria and its time-dynamics in a select group treated for biopsy proven antibody-mediated rejection (ABMR). METHODS: Eighty-five patients who underwent transplantation were enrolled in our study and followed up from transplantation until October 31, 2020, death, or the date of the return to dialysis. We created two main groups: the ABMR group (n = 19) and an ABMR-negative control group with stable kidney function (n = 52) without donor-specific antibodies (DSA) and a subgroup with DSAs but stable graft function (n = 14) without ABMR. Differences in patient, donor, and transplant graft characteristics between the groups were assessed by Fisher's exact test for categorical variables. Death-censored graft loss was evaluated with the help of Kaplan-Meier analysis using log risk statistics. RESULTS: Proteinuria decreased after treatment in the ABMR group (P < .0009). Pre-treatment every 10 mg/mmol increase in proteinuria was associated with a 7% increase in the risk for graft failure in the ABMR group. The estimated 3-year graft survival was 87.5% in the ABMR group, compared to 93% in the group without ABMR but with pre-formed DSA, and 100% in the DSA negative subgroup (log-rank probe P < .0666). CONCLUSION: Proteinuria is an independent predictor for graft failure, can be lowered by treatment for ABMR but ABMR is associated with lower graft survival in our study population.

Increased level of platelet P-selectin in nonarteritic anterior ischemic optic neuropathy.

PURPOSE: P-selectin receptor is expressed in platelets and endothelial cells in a cell-activation-dependent manner. Platelet P-selectin (CD62) levels may become elevated in a number of vasoocclusive diseases, including arteriosclerosis, atherothrombosis, and diabetes mellitus (DM). Nonarteritic anterior ischemic optic neuropathy (NAION) is associated with a sudden loss of vision due to the vascular insufficiency of ciliary arteries supplying the optic nerve. In this study, our aim was to investigate the presence of increased platelet reactivity in the development of NAION. METHODS: Twenty-one NAION patients, 39 healthy control subjects, and 44 patients suffering from diabetes mellitus (DM) were examined in our case-control, pilot study. Platelet activation was investigated by flow cytometric analysis of the mean fluorescence intensity (MFI) of CD62 on platelets. These results were compared among the different study groups. RESULTS: NAION patients showed considerably although not significantly (p = 0.2017) higher P-selectin MFI values (71.98 ± 40.30) versus healthy subjects (55.48 ± 20.95), insulin-dependent DM patients (50.02 ± 13.08), and non-insulin-dependent DM subjects (54.72 ± 24.74). However, logistic regression analysis resulted in a statistically significant adjusted effect on the odds of NAION when CD62 MFI values were logarithmically transformed (OR: 3.86, 95 % CI: 1.10 to 13.53, p = 0.0346). CONCLUSION: Elevated platelet CD62 positivity may be related to NAION, suggesting a possible role of enlarged platelet activity in the generation of this type of ischemic optic neuropathy.

[Experiences with a self developed accelerometer]. / Saját fejlesztésu mozgásérzékelovel szerzett tapasztalataink.

OBJECTIVE: In neurology the objective evaluation of improvement of paresis on every-day practice. The aim of this study was to develop and test a small 3-d acceleration measuring device and validate its usefulness. PATIENTS AND METHODS: We collected data from 17 mild and medium severity hemiparetic, bedridden acute ischaemic and hemorrhagic stroke patients and compared with data of 22 control subjects. The devices were attached to the paretic and non-paretic extremities and any movements (m/s2) and movement-durations were registered (24h). The data of movement-monitors were compared also with the changes of National Institute of Health Stroke Scale and European Stroke Scale. The electromyograph-sensor of polysomnograph was used for validation. RESULTS: Mild differences could be found in the use of dominant and non-dominant upper extremities of control persons. The control persons used their upper extremities more frequently than the stroke patients. Our data showed significant correlation with National Institute of Health Stroke Scale. Higher values on the scores were accompanied with less intensive use of extremities. We found a correlation between the consiousness level of patients and their activity of upper extremities. If the patients had severe consiousness disturbances they used significantly less their upper extremities. CONCLUSION: Our device sensitively detected the movement-differences between paretic and non-paretic extremities and can be used for quantitative evaluation of patient's neurological and consciousness status.

The Seattle Heart Failure Model predicts survival in patients with cardiac resynchronization therapy: a validation study.

BACKGROUND: The Seattle Heart Failure Model (SHFM) predicts mortality in patients with heart failure, but no study has investigated model performance in subjects with cardiac resynchronization therapy (CRT). METHODS AND RESULTS: Prospectively collected registry data of 427 patients with CRT were used for the evaluation of the discrimination and calibration performance of the SHFM. The primary end point was all-cause mortality. Calibration profile was assessed with the use of Hosmer-Lemeshow tests, and discrimination was assessed by calculating areas under receiver operating characteristic curves (AUCs) derived from the model. Mean (SD) age of the study population was 61.2 (11.1) years (72.6% male). During a median follow-up of 24.7 months, 16.9% (72/427) of the patients reached the primary end point, with observed outcomes of 34/303, 54/234, and 72/97 at years 1, 2, and 5, respectively. No evidence of insufficient fit was found in any calibration tests. AUC estimates in all subjects were 0.7377 (95% CI 0.6575-0.8179) at year 1, 0.7936 (95% CI 0.7317-0.8556) at year 2, and 0.7572 (95% CI 0.6455-0.8689) at year 5. CONCLUSIONS: SHFM offers an accurate prediction of survival in patients with CRT, with good observed calibration and AUC estimates indicating discrimination performance similar to those found by earlier validation studies.

Leukoaraiosis is associated with arterial wall thickness: a quantitative analysis.

Leukoaraiosis refers to an age-related, abnormal appearance of the brain white matter on neuroimaging. The association between leukoaraiosis and cerebrovascular disease suggests that ischemia may be an important contributing factor; however, the pathogenesis of the condition remains controversial. We hypothesized that physical abnormalities of blood vessels might be culpable and compared the external and internal measurements of blood vessel walls between brains that demonstrated leukoaraiosis on imaging and normal control brains. Fourteen brains of individuals who had been diagnosed as having severe leukoaraiosis and five non-leukoaraiosis control brains were studied. Arterial cross-sections were evaluated by length measurements with an image analysis device. Arterial wall thickness and the ratio of the outer and inner diameters of the vessel were measured. We measured a total of 108 vessels in the leukoaraiosis group and 95 vessels in the control group. The vessel walls of the leukoaraiosis patients were an average of 5.5 µm thicker than the walls of control vessels of the same inside diameter (P = 0.0000, 95% CI 3.01-8.08) and an average of 2.3 µm thicker than walls of control vessels of the same outside diameter (P = 0.016, 95% CI 0.48-4.17). Our data provide evidence that leukoaraiosis is associated with vessel wall thickening in an additive fashion and indicate that structural vascular abnormalities are associated with leukoaraiosis.

[The comparative analysis of arterial wall thickness and arterial wall stiffness in smoking and non-smoking university students]. / Az érfalvastagság és érfalmerevség összehasonlító vizsgálata dohányzó és nem dohányzó egyetemisták körében.

AIM: Our aim was to detect the adverse effects of smoking on arterial wall thickness and arterial wall stiffness in young, healthy university students. QUESTION: Does only a few years of smoking result in measurable vascular alterations in healthy young people? METHODS: We measured the intima-media thickness (IMT) on both common carotids by means of carotid ultrasound, then we examined the stiffnessparameters of the blood vessels (pulse wave velocity, PWV; augmentation index, Aix) with the help of arteriograph. SUBJECTS: We recruited 25 smoking and 25 non-smoking young volunteers aged 19-33 for our examinations. Exclusion citeria included any known diseases, abnormally high cholesterol levels, BMI value exceeding 30 kg/m2. Only regular smokers were allowed to participate in the smoking group (at least for six months, minimum five cigarettes a day). RESULTS: In case of smokers morphological, hemodinamic and stiffnessparameters showed significantly higher values compared to non-smokers. Mean bilateral IMT was 0.52 +/- 0.034 mm in case of smokers, while in non-smokers we measured 0.46 +/- 0.036 mm (this difference is significant: p<0.01). PWV and heart rate also showed significantly higher values in smoking group (PWV: p<0.01; heart rate: p<0.05). Unadjusted to age, gender and smoking status there was a significant correlation between IMT and PWV (0.1 mm thicker IMT - 0.6354 m/s faster PWV). Gender differences were found in vascular changes caused by smoking. CONCLUSION: The adverse effects of smoking on arterial wall thickness and arterial wall stiffness can be seen even at a young age, only after a few years of smoking. Both higher IMT and higher PWV sensitively predict vascular damages.

Clinical Spectrum and CSF Findings in Patients with West-Nile Virus Infection, a Retrospective Cohort Review.

West Nile Virus (WNV) infection is a world-wide zoonotic disease transmitted by mosquitoes. The infection is usually self-limiting; however, elderly patients or those with comorbidities are predisposed to developing severe, and sometimes fatal complications of the infection. Recently, the incidence of WNV infection in Europe had seen a sharp increase, as compared to previous years. We are currently reporting on the clinical presentation and laboratory findings in 23 cases of WNV infection, of which one resulted in a fatal outcome. The clinical picture was predominantly that of meningitis/meningoencephalitis of varying severity. One patient suffered a fatal outcome, and a rare manifestation of chorioretinal lesions and iridocyclitis was also reported as a result of WNV infection. Cerebrospinal fluid analysis predominantly showed lymphocytic pleocytosis, and total protein levels were increased in all but three of the patients. Levels of total protein in CSF samples were found to show a positive correlation with age. Given the ever-increasing incidence of WNV infection in Europe, a high index of clinical suspicion should always accompany cases of meningitis, especially during the summer period, as a similar epidemic pattern is predicted to recur.

Influenza Vaccination Coverage and Its Predictors among Self-Reported Diabetic Patients-Findings from the Hungarian Implementation of the European Health Interview Survey.

In high-risk populations, such as the elderly or those with serious medical issues, for instance, people with cardiovascular diseases or diabetes, influenza can have devastating effects because it might contribute to severe complications or even death. This makes vaccination against influenza an essential component of public health. The primary objective of our research was to identify the characteristics that influenced whether an individual chose to become vaccinated against influenza, with an emphasis on whether they reported having diabetes. The data were obtained from the Hungarian implementation of the European Health Interview Surveys, which were conducted in 2009, 2014, and 2019. The total sample size was 15,874 people. To determine the variables that were related to vaccination, a multivariate logistic regression analysis that included interactions was performed. The overall vaccination coverage was 13% in 2009 and 12% in 2014 and 2019 among non-diabetic respondents; the coverage was 26% in 2009, 28% in 2014, and 25% in 2019 among diabetic respondents. Despite vaccination coverage in both groups being below the optimal level of 75%, we were able to identify factors influencing vaccination coverage. Among diabetic respondents, younger age, lower education level, sex, and co-morbidities were factors that influenced vaccination status. It is important for authorities managing healthcare and medical practitioners to be aware of the potential effects that influenza can have on diabetic patients; therefore, more efforts need to be made to increase the number of diabetic people receiving a vaccination against influenza.

An Exploratory Assessment of Factors with Which Influenza Vaccine Uptake Is Associated in Hungarian Adults 65 Years Old and Older: Findings from European Health Interview Surveys.

Influenza vaccination is an imperative public health task for elderly people due to a higher risk of developing more severe complications. The main aim of our study was to determine the influencing factors of being vaccinated against influenza among subjects aged 65 and above. Data were from the Hungarian implementations of the European Health Interview Survey 2009, 2014 and 2019 studies with a final sample size of 3355. A multivariate logistic regression model with interactions was used to identify the possible factors associated with vaccination. Approximately 32% of the participants were vaccinated for the most recent influenza season. The most important factors were identified that contributed to influenza vaccination among individuals, which were the following: educational attainment, having a partner, the annual frequency of specialist and doctor visits, and having comorbidities. Respondents who thought that they could do a lot for their health had higher odds of being immunized. Being obese seemed to be a risk factor. According to our findings, the current influenza vaccination coverage was considered as low in Hungary; hence, the implementation of minor reformulations in the field of health policy is suggested.

Behaviour does not fully explain the high risk of chronic liver disease in less educated men in Hungary.

BACKGROUND: Hungary has among the highest mortality rates from chronic liver disease (CLD) and cirrhosis in Europe. Usually, conventional behavioural factors are hypothesized as the cause of the high risk of CLD. METHODS: A case-control study was performed with 287 cases and 892 controls to study the relationship between socio-economic and behavioural factors and the risk of CLD. Liver disease was verified by physical examination and blood tests. Blood samples were collected for detecting hepatitis B, C and E virus infection. Information on exposure factors was recorded by the participating physicians and by self-administered questionnaire. Simple regression analysis was used to study the relationship between CLD/cirrhosis and potential risk factors as alcohol intake (amount and source), problem drinking, cigarette smoking, physical activity, viral hepatitis infections, socio-economic factors (education, financial and marital status). Multiple regression analysis was used to identify whether the effect of socio-economic factors is fully mediated by health behaviour (smoking, alcohol consumption, physical activity). RESULTS: The univariate analysis showed that heavy alcohol consumption, problem drinking, former and heavy cigarette smoking, single, separated or divorced marital status, bad or very bad perceived financial status and lower education significantly increased the risk of CLD/cirrhosis. The effect of marital status and of education did not change after adjustment for behavioural factors, but the effect of perceived financial status disappeared. CONCLUSIONS: The effect of low socio-economic status on the risk of CLD/cirrhosis is only partially explained by conventional behavioural risk factors in Hungary.

[Postoperative surveillance of wound infection after cesarean section at Kenézy Hospital, Debrecen, Hungary]. / A császármetszés posztoperatív sebfertozés surveillance tapasztalatai a debreceni Kenézy Kórházban.

UNLABELLED: Wound infection is a typical, partly preventable complication of cesarean sections. We started extended recording of cesarean section data in October, 2008 as part of our general wound infection surveillance program. AIM: To describe the circumstances and outcomes of the sections and analyze associations between them. METHODS: We analyzed 523 cases over the period October 1, 2008 to September 30, 2009. Variables were assessed using descriptive statistics. Associations between explanatory factors and wound infection were evaluated using logistic regression. RESULTS: Infections (overall rate: 3.6%) were more frequent in younger subjects, those with anemia, subcutaneous hematoma, in pregnancies with meconium stained or purulent amniotic fluid, and decreased to about a third after infection control was tightened. CONCLUSIONS: by being a proxy variable of factors with which wound infection is associated, age is a clinically valuable predictive variable. Good infection control practice is effective in preventing wound infections. The results are consistent with appropriate prescription practices of prophylactic antibiotic use, and with prophylactic measures being effective.

Management of antibody-mediated rejection after kidney transplantation in our clinical practice / Az antitestmediált rejekció diagnosztikája és kezelése gyakorlatunkban.

Összefoglaló. Bevezetés: Az antitest közvetítette kilökodés a graftvesztés gyakori oka a vesetranszplantáltak körében. Célkituzés: Célul tuztük ki, hogy ismertetjük a centrumunkban biopsziával igazolt humorális kilökodéssel rendelkezo betegeknek a kezelésre (standard kezelés: plazmaferézis, immunglobulin, rituximab) adott válaszát, valamint hogy vizsgáljuk a proteinuria grafttúlélésre kifejtett hatását és azt, hogy ezt a DSA-tól függetlenül teszi-e. Vizsgáltuk az eGFR-, a DSA-MFI-értéknek az antirejekciós terápia hatására bekövetkezo változásait is. Módszer: 85 beteg retrospektív analízisét végeztük el. A szövettani elemzésben a Banff-klasszifikációt vettük alapul. A csoportok összehasonlításához kategorikus változók esetén a Fisher-féle egzakt próbát, folyamatos változók esetén a Kruskal-Wallis-próbát használtuk. Eredmények: A biopsziával igazolt humorális rejekciós csoportba (ABMR-csoport) 19, a DSA-pozitív csoportba 14, a DSA-negatív csoportba 52 beteget választottunk be. A DSA-érték az ABMR-csoportban 61,16%-kal csökkent, a DSA-pozitív csoportban 42,86%-kal redukálódott (Fisher-féle egzakt: p = 0,1). Az ABMR-csoportban 9 betegnek a jelentos, 4-nek a nephroticus mértéku proteinuriája csökkentheto volt (az ABMR-csoport 68%-a). A legjobb grafttúlélés a legalacsonyabb fehérjeürítésnél adódott. Az antirejekciós terápiát követoen készült biopsziákban: a glomerulitis, az interstitialis gyulladás, az arteritis mértéke csökkent az antihumorális kezelés hatására, azonban krónikus elváltozások jelentek meg. Következtetés: Az ABMR-csoportban az antirejekciós terápiát követoen a fehérjeürítés monitorizálása javasolt, hiszen becsülheto vele a grafttúlélés. Orv Hetil. 2021; 162(26): 1029-1037. INTRODUCTION: Antibody-mediated rejection is a common cause of graft loss among kidney transplant recipients. OBJECTIVE: We aimed to describe the response of patients with biopsy-proven humoral rejection to treatment (standard treatment: plasmapheresis, immunoglobulin, rituximab) in our center. We also analyzed the effect of proteinuria on graft survival and whether this effect is independent of donor-specific antibodies (DSAs). Changes of eGFR and level of DSA following rejection treatment were examined. METHOD: In this study, laboratory data of 85 patients were analysed. Histological analysis was based on the Banff classification. Fisher's exact test was used for statistical analysis, and Kruskal-Wallis test was used to compare patient groups per variable. RESULTS: Data from 85 patients were processed retrospectively. 19 patients were selected for the biopsy-confirmed humoral rejection group (ABMR group), 14 for the DSA-positive group, and 52 for the DSA-negative group. DSA titer decreased by 61.16% in the ABMR group after treatment and by 42.86% in the DSA-positive group (Fisher's exact test: p = 0.1). In the ABMR group, significant nephrotic proteinuria in 4 patients and severe proteinuria in 9 patients were reduced (68% of ABMR group). The patients with the lowest protein excretion had the best graft survival. In biopsies performed after antirejection therapy, the extent of glomerulitis, interstitial inflammation, arteritis decreased with antihumoral treatment, but chronic lesions appeared. CONCLUSION: Following treatment of biopsy-proven ABMR, reduction of proteinuria predicts graft survival and should be monitored as an important factor-predicting prognosis.

Measuring health-related quality of life in Hungarian children with heart disease: psychometric properties of the Hungarian version of the Pediatric Quality of Life Inventory 4.0 Generic Core Scales and the Cardiac Module.

OBJECTIVES: The aim of the study was to investigate the psychometric properties of the Hungarian version of the Pediatric Quality of Life Inventory (PedsQL) Generic Core Scales and Cardiac Module. METHODS: The PedsQL 4.0 Generic Core Scales and the PedsQL 3.0 Cardiac Module was administered to 254 caregivers of children (aged 2-18 years) and to 195 children (aged 5-18 years) at a pediatric cardiology outpatient unit. A postal survey on a demographically group-matched sample of the general population with 525 caregivers of children (aged 2-18 years) and 373 children (aged 5-18 years) was conducted with the PedsQL 4.0 Generic Core Scale. Responses were described, compared over subgroups of subjects, and were used to assess practical utility, distributional coverage, construct validity, internal consistency, and inter-reporter agreement of the instrument. RESULTS: The moderate scale-level mean percentage of missing item responses (range 1.8-2.3%) supported the feasibility of the Generic Core Scales for general Hungarian children. Minimal to moderate ceiling effects and no floor effects were found on the Generic Core Scales. We observed stronger ceiling than floor effects in the Cardiac Module. Most of the scales showed satisfactory reliability with Cronbach's alpha estimates exceeding 0.70. Generally, moderate to good agreement was found between self- and parent proxy-reports in the patient and in the comparison group (intraclass correlation coefficient range 0.52-0.77), but remarkably low agreement in the perceived physical appearance subscale in the age group 5-7 years (0.18) and for the treatment II scale (problems on taking heart medicine) scale of the Cardiac Module in children aged 8-12 years (0.39). Assessing the construct validity of the questionnaires, statistically significant difference was found between the patient group and the comparison group only in the Physical Functioning Scale scores (p = 0.003) of the child self-report component, and in Physical (p = 0.022), Emotional, (p = 0.017), Psychosocial Summary (p = 0.019) scores and in the total HRQoL (health-related quality of life) scale score (p = 0.034) for parent proxy-report. CONCLUSION: The findings generally support the feasibility, reliability and validity of the Hungarian translation of the PedsQL 4.0 Generic Core Scales and the PedsQL 3.0 Cardiac Module in Hungarian children with heart disease.

Measuring health-related quality of life in Hungarian children attending a cardiology clinic with the Pediatric Quality of Life Inventory.

The aim of the study was to evaluate health-related quality of life (HRQoL) of Hungarian children attending a pediatric cardiology outpatient unit with the Pediatric Quality of Life Inventory (PedsQL) questionnaire. The PedsQL Generic Core Scales and Cardiac Module were administered to 254 families including 195 children during a pediatric cardiology outpatient visit, and 525 families including 373 children from the general population were examined by the PedsQL Generic Core Scale by a postal survey. The relationships between PedsQL scores and patient characteristics were analyzed. Hungarian children attending a cardiology outpatient unit as an entire group and patients with severe heart diseases report significantly lower physical functioning than the general population, while more HRQoL dimensions are negatively affected according to the parents' opinion. Children with congenital heart disease of mild and great complexity also report impaired psychosocial functioning. HRQoL impairment is concentrated to the age of 5-7 years. Comparing our results with previous ones on U.S. pediatric cardiologic samples, we found significantly lower scores mainly for the physical functioning and heart symptoms subscales. This HRQoL study with an internationally well-validated instrument on children with heart disease in a Central European country highlights certain aspects of the health-care system and brings the possibility for the assessment of pediatric cardiology outcomes in a more comprehensive way.
