Enalapril Is Superior to Lisinopril in Improving Endothelial Function without a Difference in Blood-Pressure-Lowering Effects in Newly Diagnosed Hypertensives.

Angiotensin-converting enzyme (ACE) inhibitors are the primarily chosen drugs to treat various cardiovascular diseases, such as hypertension. Although the most recent guidelines do not differentiate among the various ACE inhibitory drugs, there are substantial pharmacological differences. GOAL: Here, we tested if lipophilicity affects the efficacy of ACE inhibitory drugs when used as the first therapy in newly identified hypertensives in a prospective study. METHODS: We tested the differences in the cardiovascular efficacy of the hydrophilic lisinopril (8.3 ± 3.0 mg/day) and the lipophilic enalapril (5.5 ± 2.3 mg/day) (n = 59 patients). The cardiovascular parameters were determined using sonography (flow-mediated dilation (FMD) in the brachial artery, intima-media thickness of the carotid artery), 24 h ambulatory blood pressure monitoring (peripheral arterial blood pressure), and arteriography (aortic blood pressure, augmentation index, and pulse wave velocity) before and after the initiation of ACE inhibitor therapy. RESULTS: Both enalapril and lisinopril decreased blood pressure. However, lisinopril failed to improve arterial endothelial function (lack of effects on FMD) when compared to enalapril. Enalapril-mediated improved arterial endothelial function (FMD) positively correlated with its blood-pressure-lowering effect. In contrast, there was no correlation between the decrease in systolic blood pressure and FMD in the case of lisinopril treatment. CONCLUSION: The blood-pressure-lowering effects of ACE inhibitor drugs are independent of their lipophilicity. In contrast, the effects of ACE inhibition on arterial endothelial function are associated with lipophilicity: the hydrophilic lisinopril was unable to improve, while the lipophilic enalapril significantly improved endothelial function. Moreover, the effects on blood pressure and endothelial function did not correlate in lisinopril-treated patients, suggesting divergent mechanisms in the regulation of blood pressure and endothelial function upon ACE inhibitory treatment.

The Correlation between Two Angiotensin-Converting Enzyme Inhibitor's Concentrations and Cognition.

Both lisinopril and enalapril are angiotensin-converting enzyme (ACE) drugs and widely used in the treatment of hypertension. Enalapril does not cross the blood-brain barrier, but lisinopril is centrally active. Our goal was to find out if there was a link between the actual concentration of ACE inhibitors and cognition and if there was a detectable difference between the two types of ACE inhibitors. Asymptomatic, non-treated patients were diagnosed by screening and the hypertension was confirmed by ambulatory blood pressure monitoring (ABPM). A battery of cognitive tests was used to assess the impact of randomly assigning participants to receive either lisinopril or enalapril. All neurocognitive functions were measured, especially the most affected by conditions of compromised perfusion pressures, such as hypertension, which are attention and executive functions. The lisinopril concentration showed a significant inverse correlation with mosaic test (coeff. = -0.5779) and seemed to have a significant negative effect on perceptual motor skills (coeff. = -0.5779), complex attention (coeff. = -0.5104) and learning (coeff. = -0.5202). Compared with enalapril, lisinopril is less successful in improving the components of cognitive functions.

Neuropsychiatric symptoms, quality of life and caregivers' burden in dementia.

The objective of this research is to identify the relationship between the neuropsychiatric symptoms (NPSs) of patients with major neurocognitive disorder (mNCD), their quality of life, illness intrusiveness and the caregiver's burden. We assessed 131 patients with mNCD. Examination methods included WHO well-being index short version, illness intrusiveness rating scale, Alzheimer's Disease Assessment Scale-Cog, Mini Mental State Examination and neuropsychiatric inventory. The results were analysed using standard statistical tests. In our sample, the prevalence of NPSs is 100%. A significant correlation (p < 0.0001) was observed with quality of life and illness intrusiveness. Additionally, a strong relationship was observed between NPSs and the caregiver's burden (r = 0.9). The result is significantly twice as much stronger in comparison to the relationship between NPS and cognitive symptoms (r = 0.4). This is the first study in Hungary to assess the impact of NPS on the burden of relatives and quality of life. NPS had twice stronger impact on caregivers' burden than cognitive decline. However, further studies are needed to assess the sub-syndromes in mNCD in relation to NPS.

Behavioural and Psychological Symptoms in Neurocognitive Disorders: Specific Patterns in Dementia Subtypes.

BACKGROUND: Behavioural and psychological symptoms in dementia (BPSD) form an important sub-syndrome of dementia. We assessed the frequency and severity of BPSD in a random sample of Hungarian treatment-naïve dementia patients. Furthermore, we examined the relationship between cognitive symptoms and BPSD and the pattern of BPSD in specific types of dementias. METHODS: Patients (n=131) were classified into 3 groups: Alzheimer's (AD), vascular (VD), and mixed (MD) dementia. The Mini-Mental State Examination (MMSE), Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) and Neuropsychiatric Inventory (NPI) neuropsychological tests were employed. RESULTS: Mean age and MMSE score did not differ significantly among groups. BPSD was frequent (100% prevalence, NPI mean total Frequency score: 14.58, SD=7.55); abnormal motor behaviour showed the highest frequency. Hallucinations and delusions were related to the aetiology of dementia and were independent of the level of cognitive deterioration, whereas irritability, sleep-wake cycle dysfunctions, and eating-appetite change were associated with cognitive deterioration and were independent from aetiology. Both aberrant motor behaviour and disinhibition were significantly associated with aetiology and cognitive deterioration. CONCLUSIONS: BPSD symptoms are significant constituents of dementia syndromes, affecting quality of life and substantially contributing to the caregiver's burden. Specific symptom patterns can be identified in different types of dementia.

[The early recognition of mental morbidities during psycho-oncologic treatment]. / A pszichés morbiditások korai felismerése a pszichoonkológiai ellátás során.

Unfortunately there have been no positive changes in the main indicators of cancer incidence in Hungarian population since the turn of the millennium. The main goal of psycho-oncologic treatment is to provide the highest possible quality of life to the patient. The prevalence of mental disorders in cancer patients is high and it is accompanied by a rather small number of qualified staff. Thus, the remedy might be the identification of high-risk patients, i.e. the systematic psycho-oncologic screening. Hungary is still lacking a unified screening method that involves all oncologic treatment-providing units. Compiling the Hungarian standards for the Distress Thermometer and the Problem List is the first step of a complex program for creating a general psycho-oncologic screening. Such a comprehensive program might improve oncologic patient-care and, eventually, the quality and prospect of the lives of patients.

[Clinical and neuropathological characteristics of dementia with Lewy bodies]. / A Lewy-testes demencia klinikai és neuropatológiai jellemzoi.

Dementia with Lewy bodies (DLB) is the second most common neurodegenerative dementia. The accurate diagnosis is often possible only by neuropathological examination. The morphologic hallmarks are the presence of α-synuclein-rich Lewy bodies and Lewy neurites, identical to those seen in Parkinson's disease (PD) and Parkinson's disease dementia (PDD). Neurotransmitter deficits, synaptic and ubiquitin-proteasome system (UPS) dysfunction play major role in the pathomechanism. Characteristic symptoms are cognitive fluctuation, parkinsonism and visual hallucinations. Due to the often atypical clinical presentation novel imaging techniques and biomarkers could help the early diagnosis. Although curative treatment is not available, therapies can improve quality of life. Clinicopathological studies are important in exploring pathomechanisms, ensuring accurate diagnosis and identifying therapeutic targets. Orv Hetil. 2017; 158(17): 643-652.

[Specific quality of life factors in patients with inflammatory bowel disease]. / Specifikus életminoség-jellemzok egészségpszichológiai szempontú vizsgálata gyulladásos bélbetegségben szenvedo betegek körében.

INTRODUCTION: Inflammatory bowel disease is a chronic disease with a fluctuating course and unknown origin. Its two major forms are Crohn's disease and ulcerative colitis. OBJECTIVE: The authors attempted to analyse the quality of life of patients with inflammatory bowel disease as compared to healthy persons and patients with asthma in order to identify specific factors which most significantly affect the quality of life of these patients. METHOD: 269 subjects participated in the study (control group, 115 subjects; Crohn's disease, 67 patients; ulcerative colitis, 25 patients; asthma, 62 patients). The following methods were used: WHO-5, IIRS, SIBDQ and AQLQ(S) questionnaires and content analysis. RESULTS: Patients with inflammatory bowel disease had the worst quality of life with respect to both subjective well-being and burden of disease. The results obtained from questionnaires developed for the analysis of quality of life indicated that extraintestinal symptoms and emotional problems are the major factors which interfere with the quality of life of patients with inflammatory bowel disease. These findings were confirmed by content analysis of interviews with patients. CONCLUSIONS: The authors recommend that more attention should be paid to improving the quality of life of patients with inflammatory bowel disease and helping them to live with the illness, especially at the level of interpersonal relations.
