Psychometric Evaluation of the Hungarian Adaptation of the Diabetes Distress Scale in Individuals with Type 2 Diabetes.

Background and Purpose: Diabetes-specific distress (DD) is a crucial predictor of patients' self-care, necessitating reliable screening tools. The Diabetes Distress Scale captures typical sources of patients' distress effectively. Methods: The Hungarian Diabetes Distress Scale (HDDS) was employed in two studies with 450 type 2 diabetes patients. Study 1 explored DD's link to the specific quality of life, while study 2 examined its associations with depressive symptoms, anxiety, and illness perception. We evaluated HDDS's construct validity, internal consistency, and intercorrelations. Convergent validity and discriminant validity were analyzed in the second study. Results: Exploratory and confirmatory factor analyses validated HDDS's structure. Subscales exhibited strong internal consistency and correlated as expected with quality of life, anxiety, depression, illness perception, and demographic/medical data. Conclusions: The Hungarian DDS demonstrates robust psychometric properties, affirming its reliability and validity.

Effectiveness of SARS-CoV-2 primary vaccines and boosters in patients with type 2 diabetes mellitus in Hungary (HUN-VE 4 Study).

INTRODUCTION: Type 2 diabetes mellitus is a risk factor for severe COVID-19 infection and is associated with increased risk of complications. The present study aimed to investigate effectiveness and persistence of different COVID vaccines in persons with or without diabetes during the Delta wave in Hungary. RESEARCH DESIGN AND METHODS: Data sources were the national COVID-19 registry data from the National Public Health Center and the National Health Insurance Fund on the total Hungarian population. The adjusted incidence rate ratios and corresponding 95% CIs were derived from a mixed-effect negative binomial regression model. RESULTS: A population of 672 240 cases with type 2 diabetes and a control group of 2 974 102 non-diabetic persons free from chronic diseases participated. Unvaccinated elderly persons with diabetes had 2.68 (95% CI 2.47 to 2.91) times higher COVID-19-related mortality rate as the 'healthy' controls. Primary immunization effectively equalized the risk of COVID-19 mortality between the two groups. Vaccine effectiveness declined over time, but the booster restored the effectiveness against mortality to over 90%. The adjusted vaccine effectiveness of the primary Pfizer-BioNTech against infection in the 14-120 days of postvaccination period was 71.6 (95% CI 66.3 to 76.1)% in patients aged 65-100 years with type 2 diabetes and 64.52 (95% CI 59.2 to 69.2)% in the controls. Overall, the effectiveness tended to be higher in individuals with diabetes than in controls. The booster vaccines could restore vaccine effectiveness to over 80% concerning risk of infection (eg, patients with diabetes aged 65-100 years: 89.1 (88.1-89.9)% with Pfizer-on-Pfizer, controls 65-100 years old: 86.9 (85.8-88.0)% with Pfizer-on-Pfizer, or patients with diabetes aged 65-100 years: 88.3 (87.2-89.2)% with Pfizer-on-Sinopharm, controls 65-100 years old: 87.8 (86.8-88.7)% with Pfizer-on-Sinopharm). CONCLUSIONS: Our data suggest that people with type 2 diabetes may have even higher health gain when getting vaccinated as compared with non-diabetic persons, eliminating the marked, COVID-19-related excess risk of this population. Boosters could restore protection.

Determinants of the heart rate variability in type 1 diabetes mellitus.

Background: Evaluation of heart rate variability (HRV) detects the early subclinical alterations of the autonomic nervous system. Thus, impaired HRV is the earliest subclinical marker of cardiac autonomic neuropathy (CAN) in type 1 diabetes mellitus (T1DM). Objectives: We aimed to explore the HRV parameters in asymptomatic T1DM patients and compare them with the results obtained in healthy subjects. Potential associations between HRV parameters and the established risk factors for CAN and cardiovascular diseases were also investigated. Methods: Seventy T1DM patients (38 ± 12 years, 46 females) and 30 healthy subjects were enrolled into the study. For HRV analysis, beat-to-beat heart rate was recorded for 30 min. The less noisy 5-min segment of the recording was analyzed by Bittium Cardiac Navigator HRV analysis software. Time domain, frequency domain, and nonlinear indices were calculated. Results: Regarding ratio of low to high frequency component (LF/HF), no differences were found between the two populations (p = 0.227). All the further, time domain, frequency domain, and nonlinear HRV indices were significantly lower in T1DM patients (each p < 0.001). In multiple linear models, disease duration remained the only independent predictor of LF/HF ratio (p = 0.019). HbA1c was found to be significant independent predictor of all further time domain (SDNN, p < 0.001; rMSSD, p < 0.001), frequency domain (VLF, p < 0.001; LF, p = 0.002; HF, p = 0.006; Total Power, p = 0.002), and nonlinear indices (SD1, p = 0.006; SD2, p = 0.007), alone, or in combination with other factors, such as age or body mass index. Conclusion: Asymptomatic T1DM patients have significantly reduced overall HRV as compared with healthy subjects, indicating subclinical CAN. Quality of the glycemic control is important determinant of HRV among T1DM patients. This relationship is independent of other risk factors for CAN or cardiovascular diseases.

Deficiencies in the Recognition and Reporting of Chronic Kidney Disease in Patients With Type 2 Diabetes Mellitus; A Hungarian Nationwide Analysis.

Objectives: Recognition of chronic kidney disease (CKD) is crucial in type 2 diabetes mellitus (T2DM). We conducted a nationwide epidemiological study to evaluate T2DM-associated CKD in Hungary between 2016 and 2020. Methods: Annual incidence and prevalence rates of registered CKD amongst all pharmacologically treated T2DM patients were analyzed in different age-groups by the central database of the Hungarian Health Insurance Fund Management. Statistical methods included Poisson regression, Bonferroni test, Chi-square test. Results: We found 499,029 T2DM patients and 48,902 CKD patients in 2016, and 586,075 T2DM patients and 38,347 CKD patients in 2020. The majority of all prevalent T2DM and CKD patients were older (aged 60-69 years: 34.1% and 25.8%; ≥70 years: 36.1% and 64.4%, respectively). The annual incidence of T2DM and incidence rates of CKD in T2DM decreased in 2017-2020 (p < 0.001). The annual prevalence of T2DM increased (p < 0.01), the prevalence rates of CKD in T2DM were low and decreased from 9.8% to 6.5% in 2016-2020 (p < 0.001). Conclusion: Incidence and prevalence of T2DM-associated CKD decreased significantly in Hungary in 2016-2020. Lower prevalence rates of CKD may suggest under-recognition and/or under-reporting.

[One-year persistence of renin-angiotensin-aldosterone system inhibitors fixed drug combinations in hypertensive patients]. / Renin-angiotenzin-aldoszteron-rendszer-gátlók fix gyógyszer-kombinációinak egyéves perzisztenciája hypertoniás betegekben.

INTRODUCTION: Various fixed combinations of antihypertensive agents are highlighted in European and Hungarian hypertension guidelines. A renin-angiotensin-aldosterone system antagonist (RAAS inhibitor) in combination with calcium channel blockers (CCBs) or diuretics are recommended as the first step in antihypertensive therapy. OBJECTIVES: The aim of the authors was to compare the one-year persistence of RAAS inhibitor fixed-dose combinations (FDCs) in hypertension. METHOD: The authors have analyzed the prescription database of the National Health Insurance Fund and selected patients who first filled prescriptions for any RAAS inhibitor FDC between October 1, 2012, and September 30, 2013, and who did not redeem prescriptions for similar preparations in the year preceding the selection period. Apparatus of survival analysis was used, where "survival" was the time to abandon the medication. RESULTS: A total of 443 149 patients met the selection criteria. The one-year persistence of angiotensin-converting enzyme inhibitor (ACE inhibitor)/CCB FDCs was 44.59%, while that of angiotensin II receptor inhibitor (ARB)/thiazide diuretic (HCT) FDCs was 42.52%. This was followed by ACE inhibitor/indapamide FDCs at 37.27%, ARB/CCB FDCs at 29.04%, and ACE inhibitors/HCT FDCs at 27.47%. Compared to ACE inhibitor/indapamide FDCs (reference), the risk of discontinuing ACE inhibitor/CCBs was 31 percentage points lower (HR = 0.69, 95% CI 0.6855-0.6996, p<0.0001), and the risk of discontinuing ARB/HCT FDCs was 18 percentage points lower (HR = 0.82, 95% CI 0.8096-0.8267, p<0.0001). However, the risk of discontinuing ACE inhibitor/HCT FDCs was 17 percentage points higher (HR = 1.17, 95% CI 1.1562-1.1825, p<0.0001), and the risk of discontinuing ARB/CCB FDCs was 20 percentage points higher (HR = 1.20, 95% CI 1.17316-1.2239, p<0.0001). The average medication adherence time limited to 360 days was 239.9 days for ACE inhibitor/CCB FDCs, 214.8 days for ARB/HCT FDCs, 193.8 days for ACE inhibitor/indapamide FDCs, 178.8 days for ARB/CCB FDCs, and 177.6 days for ACE inhibitor/HCT FDCs. CONCLUSIONS: The authors have demonstrated that the one-year persistence of RAAS inhibitor FDCs varies significantly in hypertensive patients. ACE inhibitor/CCB FDCs were found to be the most advantageous. Orv Hetil. 2023; 164(34): 1337-1341.

[Hyponatraemia in palliative care regarding a case report]. / Hyponatraemia a palliatív ellátásban egy esetbemutatás kapcsán.

Hyponatremia is a very common abnormality in palliative care which can cause a sudden decline in the patient's general condition. The diagnostic and therapeutic procedures are based on the patient's symptoms and life-expectancy. The inadequate diagnostic and therapeutic interventions result in an unnecessary burden, while the adequate treatment could improve the quality of life. In palliative care, acute hyponatremia is very rare, the chronic form without any symptoms or mild complaints is more common. Asymptomatic patients should be observed. In patients with mild symptoms and months or years plus prognosis contributing factors should be discontinued. The electrolyte abnormality of patients with moderate or severe symptoms and at least weeks prognosis should be treated. Patients with day prognosis needs no treatment. This case report of an early palliative care patient with moderate symptoms caused by chronic, severe hyponatremia aims to give a suggestion for the management of the most common electrolyte abnormality in everyday palliative care. Orv Hetil. 2023; 164(18): 713-717.

Morbidity and mortality of patients with diabetic neuropathy treated with pathogenetically oriented alpha-lipoic acid versus symptomatic pharmacotherapies - A nationwide database analysis from Hungary.

AIMS: Diabetic neuropathy is associated with increased risk of morbidity and all-cause mortality. It is unclear whether these outcomes differ in patients with diabetic neuropathy treated with pathogenetically oriented vs symptomatic pharmacotherapies. METHODS: We performed a retrospective (2009-2019) database analysis of patients treated with pathogenetically oriented alpha-lipoic acid (ALA) or symptomatic pharmacotherapies for diabetic neuropathy. We investigated clinical outcomes in propensity score matched patients in Hungary. Changes in hazard ratios and annualized event rates were assessed and sensitivity analyses performed. RESULTS: Hazard ratios favored treatment with ALA vs symptomatic pharmacotherapies regarding acute myocardial infarction (HR 0.73, 95% CI: 0.60-0.89, p = 0.0016), stroke (HR 0.71, 95% CI: 0.62-0.82, p < 0.0001), hospitalization for heart failure (HR 0.72, 95% CI: 0.66-0.78, p < 0.0001), cancer events (HR 0.83, 95% CI: 0.76-0.92, p = 0.0002) and all-cause mortality (HR 0.55, 95% CI: 0.49-0.61, p < 0.0001), but not for lower limb amputation (HR 1.05, 95% CI: 0.89-1.25, p = 0.5455). This association was supported by results of evaluating annual event rates and sensitivity analyses. CONCLUSIONS: This retrospective database analysis revealed a lower occurrence of cardio- and cerebrovascular morbidity, cancer events and all-cause mortality in patients with diabetic neuropathy treated with pathogenetically oriented ALA vs symptomatic pharmacotherapies. This hypothesis-generating result requires further investigations.

Prevalence, Cardiometabolic Comorbidities and Reporting of Chronic Kidney Disease; A Hungarian Cohort Analysis.

Objectives: Chronic kidney disease (CKD) implies increased comorbidity burden, disability, and mortality, becoming a significant public health problem worldwide, however, prevalence data are lacking in Hungary. Methods: We determined CKD prevalence, stage distribution, comorbidities using estimated glomerular filtration rate (eGFR), albuminuria, and international disease codes in a cohort of healthcare utilizing residents within the catchment area of the University of Pécs, in the County Baranya, Hungary, between 2011 and 2019 by database analysis. The number of laboratory-confirmed and diagnosis-coded CKD patients were compared. Results: Of the total 296,781 subjects of the region, 31.3% had eGFR tests and 6.4% had albuminuria measurements, of whom we identified 13,596 CKD patients (14.0%) based on laboratory thresholds. Distribution by eGFR was presented (G3a: 70%, G3b: 22%, G4: 6%, G5: 2%). Amongst all CKD patients 70.2% had hypertension, 41.5% diabetes, 20.5% heart failure, 9.4% myocardial infarction, 10.5% stroke. Only 28.6% of laboratory-confirmed cases were diagnosis-coded for CKD in 2011-2019. Conclusion: CKD prevalence was 14.0% in a Hungarian subpopulation of healthcare-utilizing subjects in 2011-2019, and substantial under-reporting of CKD was also found.

Optimal Renal Artery-Aorta Angulation Revealed by Flow Simulation.

INTRODUCTION: In the circulatory system, the vessel branching angle may have hemodynamic consequences. We hypothesized that there is a hemodynamically optimal range for the renal artery's branching angle. METHODS: Data on the posttransplant kinetics of estimated glomerular filtration rate (eGFR) were analyzed according to the donor and implant sides (right-to-right and left-to-right position; n = 46). The renal artery branching angle from the aorta of a randomly selected population was measured using an X-ray angiogram (n = 44). Computational fluid dynamics simulation was used to elucidate the hemodynamic effects of angulation. RESULTS AND DISCUSSION: Renal transplant patients receiving a right donor kidney to the right side showed faster adaptation and higher eGFR values than those receiving a left donor kidney to the right side (eGFR: 65 ± 7 vs. 56 ± 6 mL/min/1.73 m2; p < 0.01). The average branching angle on the left side was 78° and that on the right side was 66°. Simulation results showed that the pressure, volume flow, and velocity were relatively constant between 58° and 88°, indicating that this range is optimal for the kidneys. The turbulent kinetic energy does not change significantly between 58° and 78°. CONCLUSION: The results suggest that there is an optimal range for the renal artery's branching angle from the aorta where hemodynamic vulnerability caused by the degree of angulation is the lowest, which should be considered during kidney transplantations.

[Fat tissue as the primary target organ of insulin resistance in diabetes mellitus.] / A zsírszövet mint a 2-es típusú diabetest kíséro inzulinrezisztencia egyik célszerve.

Insulin resistance is a pathological condition in which the effect of endogenous or externally administered (exogenous) insulin to promote tissue glucose uptake and utilization falls short of that observed in metabolically healthy individuals. It affects the entire organism, but the pathogenetic and underlying molecular biological processes of its selected target tissues - the liver, muscle and adipose tissue - are partially different. Recently, knowledge about the role of adipose tissue has expanded significantly, and it increasingly seems that dysfunctional adipose tissue is the central player in these pathological events. The manuscript reviews the structure of adipose tissue, the regulation of adipogenesis and lipolysis, data on the relationship between the microbiome and adipose tissue, the typical differences of the acute and chronic insulin resistance as well as the therapeutic tools currently available to reduce adipose tissue insulin resistance. It may well be that a molecule with a selective adipose tissue attack point and enabling safe long-term use in humans is not yet within the hoped-for proximity, the first animal experimental observations related to the first "adipeuticum" being under development outline the promise of a new treatment option.

Expression of Wilms-tumor 1 antigen, vimentin and corticotropin releasing factor in human kidney with focal segmental glomerulosclerosis and effect of oxidative stress on these markers in HEK 293 cells.

INTRODUCTION: Wilms-tumor 1 antigen (WT1) expression in podocytes has the important role of maintaining their integrity and glomerular function. Vimentin also plays a role in preserving podocyte function and in morphologic changes observed after injury. Corticotropin releasing factor (CRF) is important in stress and in maintaining homeostasis. According to our previous studies, tyrosine (Tyr) isoforms (meta- and ortho-Tyr) may play a role in the development of many diseases. INTRODUCTION: Wilms-tumor 1 antigen (WT1) expression in podocytes has the important role of maintaining their integrity and glomerular function. Vimentin also plays a role in preserving podocyte function and in morphologic changes observed after injury. Corticotropin releasing factor (CRF) is important in stress and in maintaining homeostasis. According to our previous studies, tyrosine (Tyr) isoforms (meta- and ortho-Tyr) may play a role in the development of many diseases. METHODS: Our aim was to investigate the expression of WT1, vimentin and CRF in human kidney and in HEK 293 cell cultures. Histological and clinical feature of 42 FSGS patients were evaluated and compared to patients with thin-basement membrane as a control group. Cells were cultured in medium containing para-, meta-, and ortho-tyrosine, and their expression of WT1, vimentin, and CRF were determined by immunocytochemistry. Podocyte foot process effacement was investigated by electron microscope (EM). RESULTS: The intensity of WT1 staining in glomeruli was the same in focal segmental glomerulosclerosis (FSGS) and control groups, but it was lower in the tubulointerstitium of FSGS patients. Vimentin was lower in glomeruli of FSGS patients (p=0.009), and it was higher in the tubulointerstitium compared to the control group (p=0.003). CRF intensity was lower in the glomeruli (p=0.002). Podocyte foot process effacement determined by electron microscope (EM) showed correlation with vimentin and CRF in glomeruli. WT1 staining intensity was lower in meta- and ortho-Tyr group (p=0.001; p=0.009). Vimentin was lower in the meta-Tyr group (p=0.001). DISCUSSION: Our observations on kidney biopsy samples support that the reduction of WT1 and vimentin could be characteristic for FSGS. Our results on HEK cells suggest that meta- and ortho-tyrosine may play a role in the development of FSGS.

Quality of glycemic control has significant impact on myocardial mechanics in type 1 diabetes mellitus.

The potential associations between disease duration, glycemic control, and the echocardiographic markers of the myocardial mechanics were investigated in asymptomatic T1DM patients. Seventy T1DM patients (38.2 ± 11.7 years, 46 female) and 30 healthy volunteers were investigated. Besides the conventional and tissue Doppler measurements, left ventricular global longitudinal (GLS) and circumferential (GCS) strain as well as left and right atrial strain parameters were measured with 2D speckle tracking technique. Median HbA1c level was 7.4 (1.8)%. Even when added age and hypertension to the model, current HbA1c level remained independent predictor of left ventricular GLS (p = 0.002), GCS (p < 0.001), mitral e' (p = 0.018), tricuspid e' (p = 0.018) and left (p = 0.039) and right atrial conduit strain (p = 0.047) in multiple linear regression models. Correlations between disease duration and the echocardiographic variables lost their significance in multiple models. In patients with a combination of HbA1c ≤ 7.4% and no hypertension, echocardiographic findings did not differ from those in healthy volunteers. Patients with HbA1c > 7.4% and no hypertension and especially patients with coexisting hypertension and HbA1c > 7.4%, exhibited significantly impaired myocardial mechanics. Quality of glycemic control has a significant impact on myocardial mechanics in T1DM patients. Regarding disease duration this relationship was not proved.

Changing Patterns of Antihyperglycaemic Treatment among Patients with Type 2 Diabetes in Hungary between 2015 and 2020-Nationwide Data from a Register-Based Analysis.

Background and objectives: In the last couple of years, pharmacological management of patients with type 2 diabetes mellitus (T2DM) have been markedly renewed. The aim of this study was to analyse the changes in prescribing patterns of antidiabetic drugs for treating patients with T2DM in Hungary between 2015 and 2020. Material and Methods: In this retrospective, nationwide analysis, we used the central database of the National Health Insurance Fund. We present annual numbers and their proportion of T2DM patients with different treatment regimens. Results: In the period of 2015−2020, the number of incident cases decreased from 60,049 to 29,865, while prevalent cases increased from 682,274 to 752,367. Patients with metformin (MET) monotherapy had the highest prevalence (31% in 2020). Prevalence of insulin (INS) monotherapy continuously but slightly decreased from 29% to 27% while that of sulfonylurea (SU) monotherapy markedly decreased from 37% to 20%. Dipeptidyl peptidase (DPP-4) inhibitors remained popular in 2020 as monotherapy (5%), in dual combination with MET (12%) and in triple combination with MET and SU (5%). The prevalence of patients with sodium-glucose co-transporter-2 (SGLT-2) inhibitors increased from 1% to 4% in monotherapy, from <1% to 6% in dual combination with MET, and from <1% to 2% in triple oral combination with MET and SU or DPP-4-inhibitors. The prevalence of patients using glucagon-like peptide-1 receptor agonists (GLP-1-RAs) also increased but remained around 1−2% both in monotherapy and combinations. For initiating antihyperglycaemic treatment, MET monotherapy was the most frequently used regime in 2020 (50%), followed by monotherapy with SUs (16%) or INS (10%). After initial MET monotherapy, the incidence rates of patients with add-on GLP-1-RAs (2%, 3%, and 4%) and those of add-on SGLT-2 inhibitors (4%, 6%, and 8%) slowly increased in the subsequent 24, 48, and 72 months, respectively. Conclusions: In the period of 2015−2020, we documented important changes in trends of antihyperglycaemic therapeutic patterns in patients with T2DM which followed the new scientific recommendations but remained below our expectations regarding timing and magnitude. More efforts are warranted to implement new agents with cardiovascular/renal benefits into therapeutic management in time, in a much larger proportion of T2DM population, and without delay.

Effectiveness and Waning of Protection With Different SARS-CoV-2 Primary and Booster Vaccines During the Delta Pandemic Wave in 2021 in Hungary (HUN-VE 3 Study).

Background: In late 2021, the pandemic wave was dominated by the Delta SARS-CoV-2 variant in Hungary. Booster vaccines were offered for the vulnerable population starting from August 2021. Methods: The nationwide HUN-VE 3 study examined the effectiveness and durability of primary immunization and single booster vaccinations in the prevention of SARS-CoV-2 infection, Covid-19 related hospitalization and mortality during the Delta wave, compared to an unvaccinated control population without prior SARS-CoV-2 infection. Results: The study population included 8,087,988 individuals who were 18-100 years old at the beginning of the pandemic. During the Delta wave, after adjusting for age, sex, calendar day, and chronic diseases, vaccine effectiveness (VE) of primary vaccination against registered SARS-CoV-2 infection was between 11% to 77% and 18% to 79% 14-120 days after primary immunization in the 16-64 and 65-100 years age cohort respectively, while it decreased to close to zero in the younger age group and around 40% or somewhat less in the elderly after 6 months for almost all vaccine types. In the population aged 65-100 years, we found high, 88.1%-92.5% adjusted effectiveness against Covid-19 infection after the Pfizer-BioNTech, and 92.2%-95.6% after the Moderna booster dose, while Sinopharm and Janssen booster doses provided 26.5%-75.3% and 72.9%-100.0% adjusted VE, respectively. Adjusted VE against Covid-19 related hospitalization was high within 14-120 days for Pfizer-BioNTech: 76.6%, Moderna: 83.8%, Sputnik-V: 78.3%, AstraZeneca: 73.8%, while modest for Sinopharm: 45.7% and Janssen: 26.4%. The waning of protection against Covid-19 related hospitalization was modest and booster vaccination with mRNA vaccines or the Janssen vaccine increased adjusted VE up to almost 100%, while the Sinopharm booster dose proved to be less effective. VE against Covid-19 related death after primary immunization was high or moderate: for Pfizer-BioNTech: 81.5%, Moderna: 93.2%, Sputnik-V: 100.0%, AstraZeneca: 84.8%, Sinopharm: 58.6%, Janssen: 53.3%). VE against this outcome also showed a moderate decline over time, while booster vaccine types restored effectiveness up to almost 100%, except for the Sinopharm booster. Conclusions: The HUN-VE 3 study demonstrated waning VE with all vaccine types for all examined outcomes during the Delta wave and confirmed the outstanding benefit of booster vaccination with the mRNA or Janssen vaccines, and this is the first study to provide clear and comparable effectiveness results for six different vaccine types after primary immunization against severe during the Delta pandemic wave.

Management of diabetes in patients receiving palliative care / A diabetes mellitus kezelése palliatív ellátásban részesülo betegekben

Introduction: The prevalence of diabetes mellitus is increasing worldwide. According to Hungarian data from 2014, it affects 7,3% of the population. At the time of their cancer diagnosis, 8-18% of all patients have preexisting diabetes mellitus. Some studies have identified a diabetes prevalence up to 30% of cancer patients. The treatment of diabetic patients in palliative care differs from the curative methods and this is very important to be communicated with the patient, the family members and health-care providers. Objective: The aim of this publication is to develop a method of control and treatment of the palliative care patients with diabetes mellitus. Method: Based on studies in international literature, a suggestion can be made that can be applied in domestic practice. Suggestions: This suggestion introduces individual and more liberal control and management methods for a better quality of life in this special patient group. Conclusion: The suggestion for the treatment of diabetes helps provide quality care for palliative patients.

Effect of HEAT therapy in patiEnts with type 2 Diabetes mellitus (HEATED): protocol for a randomised controlled trial.

INTRODUCTION: The burden of type 2 diabetes mellitus (T2DM) is increasing worldwide. Heat therapy has been found effective in improving glycaemic control. However, to date, there is a lack of randomised controlled studies investigating the efficacy of heat therapy in T2DM. Therefore, we aim to investigate whether heat therapy with natural thermal mineral water can improve glycaemic control in patients with T2DM. METHODS AND ANALYSIS: The HEAT therapy in patiEnts with type 2 Diabetes mellitus (HEATED) Study is a single-centre, two-arm randomised controlled trial being conducted at Harkány Thermal Rehabilitation Centre in Hungary. Patients with T2DM will be randomly assigned to group A (bath sessions in 38°C natural thermal mineral water) and group B (baths in thermoneutral water (30°C-32°C)). Both groups will complete a maximum of 5 weekly visits, averaging 50-60 visits over the 12-week study. Each session will last 30 min, with a physical check-up before the bath. At baseline, patients' T2DM status will be investigated thoroughly. Possible microvascular and macrovascular complications of T2DM will be assessed with physical and laboratory examinations. The short form-36 questionnaire will assess the quality of life. Patients will also be evaluated at weeks 4, 8 and 12. The primary endpoint will be the change of glycated haemoglobin from baseline to week 12. An estimated 65 patients will be enrolled per group, with a sample size re-estimation at the enrolment of 50% of the calculated sample size. ETHICS AND DISSEMINATION: The study has been approved by the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (818-2/2022/EÜIG). Written informed consent is required from all participants. We will disseminate our results to the medical community and will publish our results in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov, NCT05237219.

Non-alcoholic fatty liver disease and type 2 diabetes mellitus. II. Treatment / A nem alkoholos zsírmájbetegség és a 2-es típusú cukorbetegség. II. Kezelés

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease. Non-alcoholic steatohepatitis (NASH), the aggressive form of NAFLD can progress to cirrhosis, and is becoming the leading cause of end-stage liver disease. NAFLD and NASH are prevalent in obese individuals and frequently coexist with type 2 diabetes mellitus as well as cardiovascular and renal complications. There is no approved therapy for the treatment of NAFLD and NASH. Their current management focuses on controlling risk factors, and lifestyle modification, weight reduction, caloric restriction, diet and exercise, but these can be difficult to achieve and maintain. Thus, there is an urgent need for effective pharmacotherapy. This review summarizes pharmacological agents available to treat diabetes mellitus, the main risk factor of NAFLD, drugs that could potentially be useful also for the therapy of NASH. Furthermore, we describe novel therapies targeting different pathogenic pathways of NAFLD, several agents that are under development specifically for the treatment of NASH. These new classes of medications may target hepatic fat accumulation, de novo lipogenesis, farnesoid X receptor-bile acid axis, oxidative stress, inflammation, gut microbiome and fibrogenesis. Until now, the use of pioglitazone and vitamin E has only been recommended by guidelines for selected patient groups with biopsy-proven NASH. It is likely that in the future, the combination of different types of targeted pharmacotherapies will provide an effective treatment for NASH. Since NAFLD is a systemic metabolic disease, cooperation between diabetologists, nephrologists, cardiologists and hepatologists is also highly advised in the management of these patients.

Nationwide Effectiveness of First and Second SARS-CoV2 Booster Vaccines During the Delta and Omicron Pandemic Waves in Hungary (HUN-VE 2 Study).

Background: In Hungary, the pandemic waves in late 2021 and early 2022 were dominated by the Delta and Omicron SARS-CoV-2 variants, respectively. Booster vaccines were offered with one or two doses for the vulnerable population during these periods. Methods and Findings: The nationwide HUN-VE 2 study examined the effectiveness of primary immunization, single booster, and double booster vaccination in the prevention of Covid-19 related mortality during the Delta and Omicron waves, compared to an unvaccinated control population without prior SARS-CoV-2 infection during the same study periods. The risk of Covid-19 related death was 55% lower during the Omicron vs. Delta wave in the whole study population (n=9,569,648 and n=9,581,927, respectively; rate ratio [RR]: 0.45, 95% confidence interval [CI]: 0.44-0.48). During the Delta wave, the risk of Covid-19 related death was 74% lower in the primary immunized population (RR: 0.26; 95% CI: 0.25-0.28) and 96% lower in the booster immunized population (RR: 0.04; 95% CI: 0.04-0.05), vs. the unvaccinated control group. During the Omicron wave, the risk of Covid-19 related death was 40% lower in the primary immunized population (RR: 0.60; 95% CI: 0.55-0.65) and 82% lower in the booster immunized population (RR: 0.18; 95% CI: 0.16-0.2) vs. the unvaccinated control group. The double booster immunized population had a 93% lower risk of Covid-19 related death compared to those with only one booster dose (RR: 0.07; 95% CI. 0.01-0.46). The benefit of the second booster was slightly more pronounced in older age groups. Conclusions: The HUN-VE 2 study demonstrated the significantly lower risk of Covid-19 related mortality associated with the Omicron vs. Delta variant and confirmed the benefit of single and double booster vaccination against Covid-19 related death. Furthermore, the results showed the additional benefit of a second booster dose in terms of SARS-CoV-2 infection and Covid-19 related mortality.

Plasma Levels and Renal Handling of Amino Acids Contribute to Determination of Risk of Mortality or Feed of Ventilation in Patients with COVID-19.

COVID-19 infection may lead to serious complications, e.g., need for mechanical ventilation or death in some cases. A retrospective analysis of patients referred to our COVID Emergency Department, indiscriminately, was performed. A routine lab analysis measured amino acids in plasma and urine of patients. Data of surviving and deceased patients and those requiring or not requiring mechanical ventilation were compared, and logistic regression analyses have been performed. Deceased patients were older, had higher blood glucose, potassium, AST, LDH, troponin, d-dimer, hsCRP, procalcitonin, interleukin-6 levels (p < 0.05 for all). They had lower plasma serine, glycine, threonine, tryptophan levels (p < 0.01), higher tyrosine and phenylalanine levels (p < 0.05), and higher fractional excretion of arginine, methionine, and proline (p < 0.05) than survivors. In a regression model, age, severity score of COVID-pneumonia, plasma levels of threonine and phenylalanine were predictors of in-hospital mortality. There was a difference in ventilated vs. non-ventilated patients in CT-scores, glucose, and renal function (p < 0.001). Using logistic regression, CT-score, troponin, plasma level, and fractional excretion of glycine were predictors of ventilation. Plasma levels and renal excretion of certain amino acids are associated with the outcome of COVID-19 infection beside other parameters such as the CT-score or age.
