IBRAHIM Munir Yasmin, BORDA Bernadett, LENGYEL Csaba, VÁRKONYI Tamás, KEMÉNY Éva, SZABÓ Viktor, KUBIK András, LÁZÁR György

[Introduction: New-onset diabetes after transplantation (NODAT) is one of the most common complications following kidney transplantation. The diagnosis of NODAT is often late or missed, therefore it impairs the implanted renal allograft. Patients and methods: Patients were randomized to receive cyclosporine A- or tacrolimusbased immunosuppression. One year after the transplantation, fasting and oral glucose tolerance tests were performed, and the patients were assigned to one of the following three groups based on the results: normal, impaired fasting glucose/impaired glucose tolerance (IFG/IGT), NODAT. Age, laboratory results, renal function, morphological abnormalities, and changes in the Banff score were evaluated. Results: NODAT developed in 14% of patients receiving cyclosporine A-based immunosuppression and in 26% of patients taking tacrolimus (p=0.0002). Albumin levels were similar, but uric acid level (p=0.002) and the age of the recipient (p=0.003) were significantly different between the diabetic and the normal group. The evaluation of renal function showed no significant differences in case of serum creatinine level, eGFR, and urea level. Evaluation of tissue samples revealed that acute cellular rejection (ACR) and interstitial fibrosis/ tubular atrophy (IF/TA) were significantly different in the NODAT group. Changes in the Banff score provided significant difference regarding tubulitis (“t”) and interstitial inflammation (“i”) (p=0.05). Discussion: The pathological effect of new-onset diabetes after kidney transplantation can be detected in the morphology of the renal allograft earlier, before any signs of functional impairment.]

[Monitoring of effectiveness of ramipril-amlodipine fixed combination, a non-interventional trial (Ramona study). Subgroup analysis of patients with chronic kidney disease]

SIMONYI Gábor

[Hypertension and chronic kidney disease are independent cardiovascular risk factors. The 5th Cardiovascular Consensus Conference has recommended chronic kidney disease in high-risk category. In chronic kidney disease hypertension is observed in most cases. In patients with chronic kidney disease blood pressure targets are as 140/90 mmHg blood pressure below must be achieved without overt proteinuria. In chronic kidney disease combined antihypertensive therapy treatment should be initiated according the Hungarian Society of Hypertension recommendations. Aims: Monitoring the effectiveness and safety of the fix combination of ramipril/amlodipine Egiramlon® therapy in chronic kidney disease suffering from mild or moderate hypertension despite antihypertensive treatment. Patients and methods: Open, prospective, phase IV clinical observational study, which involved known chronic kidney disease (age over 18 years) with mild or moderate hypertension. Ramipril/amlodipine fixed combination (5/5, 5/10, 10/5 or, 10/10 mg) were administered or titrated in three visits, during the 4 months of trial period. The doses of the fixed combination drugs were determined individually during the visits by the 923 physicians involved in the study. The target blood pressure value was <140/90 mmHg according the new guidelines of ESH/ESC. Results: 70.1% of total patient (9169) was fulfilled the protocol during the four month of trial (6423 patients). In this population 194 patients suffered from chronic kidney disease. The age of patients was 68.52±1.84 (mean±SD) years, 85 (43.8) women and 109 (56.2%) men. 74.74% of total patients with chronic kidney disease has reached target blood pressure at the end of 4th month (primary endpoint). The blood pressure has decreased significantly (all p<0.0001) from 158.04/90.46±9.97/8.30 mmHg (1. visit) to 138.77/82.12±10.68/7.21 mmHg 2. visit and to 130.40/78.59±7.56/5.75 at the and of trial (3. visit), it means -27.64/- 11.87 mmHg decrease from the beginning of the 4th Month (3. visit). eGFR level increased significantly from 46.3±16.49 ml/min/1,73m2 to 49.0±19.58 ml/min/1,73m2. Patients suffered from chronic kidney disease have tolerated well the various doses of fixed combination of ramipril/amlodipine, and adverse events have no occurred correlation of treatment.]

[Change in prescribing RAS inhibitors with respect of data of National Health Insurance Fund (NHIF)]

BARNA István, GYURCSÁNYI András

[The authors examined and analyzed monthly data of accounted prescription sales that were supported by the National Health Insurance Fund. They wished to determine how the use of angiotensin-converting enzyme inhibitors (ACE inhibitors) and angiotensin receptor blockers (ARB) had changed. They separately evaluated how much this data was in accordance with the several, recently published articles about clinical trial results that compared inhibitors of the renin-angiotensin system (RAS inhibitors). It seemed worthwhile to examine the use of RAS inhibitors in Hungary and more specifically where RAS inhibitors stand among subsidized drugs based on the National Health Insurance Fund (OEP) database. The processed data was obtained from the National Health Insurance database, in the Decembers of 2007-2012 years and was based on prescription sales in pharmacies that were accounted for by the National Health Insurance Fund. During the data analysis we examined the number of prescriptions accounted for by looking at ATC codes and molecules, and examined the number of products (brands) available by ATC with Social Insurance Support in the given period. We examined the monthly turnover of ACE inhibitors and ARB products and the kedveamount of Social Insurance Support on these prescriptions in the given period. Next, we analyzed how much the average cost of prescriptions was by ATC codes and what kind of molecules have been available in Hungary with Social Insurance Support according to ATC codes.]

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

[The connection between the socioeconomic status and stroke in Budapest]

VASTAGH Ildikó, SZŐCS Ildikó, OBERFRANK Ferenc, AJTAY András, BERECZKI Dániel

[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

[Association between cyclothymic affective temperament and hypertension]

NEMCSIK János, BATTA Dóra, KŐRÖSI Beáta, RIHMER Zoltán

[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]

VÁLYI Péter

[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]

Life threatening rare lymphomas presenting as longitudinally extensive transverse myelitis: a diagnostic challenge

TOLVAJ Balázs, HAHN Katalin, NAGY Zsuzsanna, VADVÁRI Árpád, CSOMOR Judit, GELPI Ellen, ILLÉS Zsolt, GARZULY Ferenc

Background and aims – Description of two cases of rare intravascular large B-cell lymphoma and secondary T-cell lymphoma diagnosed postmortem, that manifested clinically as longitudinally extensive transverse myelitis (LETM). We discuss causes of diagnostic difficulties, deceptive radiological and histological investigations, and outline diagnostic procedures based on our and previously reported cases. Case reports – Our first case, a 48-year-old female was admitted to the neurological department due to paraparesis. MRI suggested LETM, but the treatments were ineffective. She died after four weeks because of pneumonia and untreatable polyserositis. Pathological examination revealed intravascular large B-cell lymphoma (IVL). Our second case, a 61-year-old man presented with headache and paraparesis. MRI showed small bitemporal lesions and lesions suggesting LETM. Diagnostic investigations were unsuccessful, including tests for possible lymphoma (CSF flow cytometry and muscle biopsy for suspected IVL). Chest CT showed focal inflammation in a small area of the lung, and adrenal adenoma. Brain biopsy sample from the affected temporal area suggested T-cell mediated lymphocytic (paraneoplastic or viral) meningoencephalitis and excluded diffuse large B-cell lymphoma. The symptoms worsened, and the patient died in the sixth week of disease. The pathological examination of the presumed adenoma in the adrenal gland, the pancreatic tail and the lung lesions revealed peripheral T-cell lymphoma, as did the brain and spinal cord lesions. Even at histological examination, the T-cell lymphoma had the misleading appearance of inflammatory condition as did the MRI. Conclusion – Lymphoma can manifest as LETM. In cases of etiologically unclear atypical LETM in patients older than 40 years, a random skin biopsy (with subcutaneous adipose tissue) from the thigh and from the abdomen is strongly recommended as soon as possible. This may detect IVL and provide the possibility of prompt chemotherapy. In case of suspicion of lymphoma, parallel examination of the CSF by flow cytometry is also recommended. If skin biopsy is negative but lymphoma suspicion remains high, biopsy from other sites (bone marrow, lymph nodes or adrenal gland lesion) or from a simultaneously existing cerebral lesion is suggested, to exclude or prove diffuse large B-cell lymphoma, IVL, or a rare T-cell lymphoma.
