Lege Artis Medicinae - 2005;15(08-09)

[Pathologist have recognized arterial calcification for over a century described also by Virchow in the 19th century. Vascular calcification, an active mechanism, involves a complex, regulated process of biomineralization resembling osteogenesis. Evidence indicates that proteins controlling bone mineralization are also involved in the regulation of vascular calcification. The atherosclerotic plaque calcification can be easily detected noninvasively with radiological methods currently available and it correlates with the amount of atherosclerotic plaque. Also, it serves as a surrogate measure for atherosclerosis, allowing preclinical detection of the disease. There are several examples for the relationship between hyperlipidaemia and increased loss of bone mass. It is not surprising that the base drugs for osteoporosis also have the characteristics for lowering vascular calcification and are antiatherogenous and antilipaemic drugs. The clinical importance ot these facts is that vascular calcification is associated with higher risk of cardiovascular events. In the summary, the authors review the four histopathological types of arterial calcification and the molecules and proteins involved in these processes.]

[MARITAL STRESS, DEPRESSIVE SYMPTOMS AND CARDIOVASCULAR VULNERABILITY IN WOMEN]

BALOG Piroska, MÉSZÁROS Eszter

[INTRODUCTION - Marital stress and depression have proved to be independent biopsychosocial risk factors for cardiovascular disorders. At the same time their interaction increases cardiovascular vulnerability. The Stockholm Female Coronary Risk Study has shown that marital stress was statistically significantly associated with depressive symptoms, in both groups of healthy women and in patients, even after adjusting for age, educational level, menopausal status, body mass index, cigarette smoking, sedentary lifestyle and the severity of heart failure. METHODS - The aim of this study was to investigate the effect of marital stress on depressive symptoms and psychosocial vulnerability in women with coronary heart disease and in healthy women, cohabiting and currently working. Data were obtained from the Hungarostudy 2002, representing the Hungarian population over the age of 18, according to age, sex and county. RESULTS - The results have shown that an increase in marital stress contributes to an increase in psychosocial vulnerability (depression, anxiety, vital exhaustion, sleep complaints) in healthy women and in women with cardiovascular disorders as well. Higher depression has been related with higher marital stress as well. DISCUSSION - The relation between marital stress and depression seems to be independent from socio-cultural, economical differences: the same results have been found in Hungarian and Swedish women. This relation seems to be bidirectional: a bad marriage increases the prevalence rate of depressive symptoms and depression worsens marital quality. At the end we propose a conceptual framework for how marital stress and depression increases cardiovascular vulnerability in women, emphasizing circular causality.]

[THE INFLUENCE OF GASTROESOPHAGEAL REFLUX DISEASE AND ITS TREATMENT ON ASTHMATIC COUGH]

BÖCSKEI Csaba, VICZIÁN Magdolna, BÖCSKEI Renáta, HORVÁTH Ildikó

[INTRODUCTION - Gastroesophageal reflux is known to cause chronic cough and it is also implicated in worsening of asthma. We conducted a prospective study to examine the clinical significance of gastroesophageal reflux disease in asthmatic patients with chronic cough, to analyse the temporal relationship between reflux events and coughing and to assess the effect of esomeprazole treatment on respiratory symptoms and lung function in these patients. PATIENTS AND METHODS - 126 asthmatic patients with chronic dry cough were studied. Diagnosis of gastroesophageal reflux disease was based on typical symptoms and the effectiveness of therapeutic test or on pH monitoring, while control group consisted of the patients without gastroesophageal reflux (negative pH results). The study group patients received the proton pump inhibitor esomeprazole (40 mg/day for three months) and standard treatment for asthma was continued. During the study pulmonary function tests (forced expiratory volume in one second and peak expiratory flow) were evaluated four times and the reflux symptom scores as well, using a questionnaire. RESULTS - The results of pH monitoring showed that 64% of cough episodes were related to acid reflux and in 91% of reflux events preceded coughing. Esomeprazole treatment (40 mg/day for three months) not only diminished gastroesophageal reflux symptoms but also improved asthma outcome measures. Baseline pulmonary function values increased significantly together with a decrease in symptom scores and the use of rescue medication. In most patients included in the extended part of the study for another three months, the dose of inhaled steroids could be reduced with sustained therapy against gastroesophageal reflux. CONCLUSION - Our data shows that reflux events preceded coughing in most cases and that treatment of gastroesophageal reflux disease caused an improvement in different outcome measures of asthma suggest that gastroesophageal reflux disease worsens asthma and its treatment is of clinical importance in the effective management of these patients.]

[BIVENTRICULAR PACING - A NEW TREATMENT OPTION IN CONGESTIVE HEART FAILURE]

BŐHM Ádám

[Cardiac resynchronisation therapy with biventricular pacing is a new treatment option in patients with moderate-to-advanced heart failure and left bundle branch block. Cardiac resynchronisation therapy leads to improved haemodynamics at diminished energy cost. Beneficial effects include reverse remodelling resulting in decreased heart size and ventricular volumes, improved ejection fraction and decreased functional mitral regurgitation. The haemodynamic improvements are associated with a significantly better quality of life, improved exercise tolerance and less frequent hospitalisation. Several randomised trials have evaluated the short- and longterm effect of biventricular pacing on haemodynamics and clinical parameters and recent preliminary data suggest that cardiac resynchronisation therapy can reduce the mortality. Despite major advances of lead and pacemaker techniques, the implantation of a biventricular pacemaker is still a challenging and complex procedure. To introduce the left ventricular pacing lead into the sinus coronarius may cause difficulties. Approximately one third of the patients do not respond to the therapy, therefore better pre-implant identification of the responders are needed. For patient selection and follow- up echocardiography has a major role.]

[TRAVEL MEDICINE IN GP PRACTICE]

FELKAI Péter, KOVÁCS Erzsébet

[The authors describe the basic ideas of travel medicine, as a newly introduced interdiscipline of the medical science in Hungary. Recently, this segment is considered to be the part of Insurance Medicine, on the other hand the methods and the practice of the travel medicine is based on the other medical specialities’ knowledge. Due to the growing number of travellers in our country as well as the consequences of the joining Hungary to EU, travel medicine could play an important role in the improvement of the Hungarian travellers’ attitude to their health care status, the prevention against the emerged infectious diseases, and in the medical assistance for the international tourism. Travel medicine also a good guideline for the fit-for-travel considerations, made by the GPs. Hungary with its advantageous geographical position appears to be an excellent stopover for any medical evacuation from East European or other surrounding countries. That is why we would like to establish a first travel medicine facility in central Europe. It is expectable that the Hungarian travellers require more and more information regarding to their health care possibilities and prevention during their trip. The first authentic person is being asked by the patients’ are GPs. The GP’s tasks are: diagnosis and the treatment of travel related diseases, the pre-travel advices. All the mentioned factors are a new challenge for the GPs in Hungary.]

[Identifying osteoporosis in a primary care setting with quantitative ultrasound]

HIRDI Henriett Éva, SZOBOTA Lívia

[Osteoporosis is one of the most under-diagnosed and under-treated health conditions. In recent decades, several risk indices have been developed to identify women at risk for low bone mineral density (BMD) who require a BMD test. This study aimed to demonstrate that quantitative ultrasound bone density measurement can indeed be performed simply by nurses working in primary care, which can significantly facilitate early detection of osteopenic and osteoporotic conditions. Method: The medical records of all patients who had an ultrasound of the left heel using the quantitative heel ultrasound machine between March 2021 through December 2021 were reviewed retrospectively. The subjects were 20-64-year-old adults (N=1032). Calcaneal quantitative ultra­sound parameters were registered with Sonost-2000 bone densitometer. The body composition was measured using a multi-frequency segmental body composition analyzer. The measurement results were evaluated with SPSS 22.0 statistical program and descriptive statistics. The mean age of the population studied was 43.12±9.6 years; 29.7% were men and 70.3% were women. Of the women in our study, 2.4% were osteoporotic (T ≤ −2.5), and 49.86% were classified as osteopenic according to the WHO operational definition. Osteopenic values were measured in 32.35% of men. A total of 273 subjects (26.45%) in the study sample were in the 50-64 age group (223 women and 50 men). 4% of women over the age of 50 had osteoporosis and 63.7% had osteopenia. Rating of the OST score no one was placed in the high-risk group. Of the 9 women with osteoporosis, 8 were classified as low-risk and 1 as medium based on OST. Nurses in primary care are able to identify key risk factors for osteoporosis, examine the measurement with quantitative ultrasound, and identify individuals with the disease. ]

Management of bone metabolism in epilepsy

UÇAN TOKUÇ Ezgi Firdevs , FATMA Genç, ABIDIN Erdal, YASEMIN Biçer Gömceli

Many systemic problems arise due to the side effects of antiepileptic drugs (AEDs) used in epilepsy patients. Among these adverse effects are low bone mineral density and increased fracture risk due to long-term AED use. Although various studies have supported this association with increased risk in recent years, the length of this process has not been precisely defined and there is no clear consensus on bone density scanning, intervals of screening, and the subject of calcium and vitamin D supplementation. In this study, in accordance with the most current recommendations, our applications and data, including the detection of possible bone mineralization disorders, treatment methods, and recommendations to prevent bone mineralization disorders, were evaluated in epilepsy patients who were followed up at our outpatient clinic. It was aimed to draw attention to the significance of management of bone metabolism carried out with appropriate protocols. Epilepsy patients were followed up at the Antalya Training and Research Hospital Department of Neurology, Epilepsy Outpatient Clinic who were at high risk for osteoporosis (use of valproic acid [VPA] and enzyme-inducing drugs, using any AED for over 5 years, and postmenopausal women) and were evaluated using a screening protocol. According to this protocol, a total of 190 patients suspected of osteoporosis risk were retrospectively evaluated. Four patients were excluded from the study due to secondary osteoporosis. Of the 186 patients who were included in the study, 97 (52.2%) were women and 89 (47.8%) were men. Prevalence of low bone mineral density (BMD) was 42%, in which osteoporosis was detected in 11.8% and osteopenia in 30.6% of the patients. Osteoporosis rate was higher at the young age group (18-45) and this difference was statistically significant (p=0.018). There was no significant difference between male and female sexes according to osteoporosis and osteopenia rates. Patients receiving polytherapy had higher osteoporosis rate and lower BMD compared to patients receiving monotherapy. Comparison of separate drug groups according to osteoporosis rate revealed that osteoporosis rate was highest in patient groups using VPA+ carbamazepine (CBZ) (29.4%) and VPA polytherapy (19.4%). Total of osteopenia and osteoporosis, or low BMD, was highest in VPA polytherapy (VPA+ non-enzyme-inducing AED [NEID]) and CBZ polytherapy (CBZ+NEID) groups, with rates of 58.3% and 55.1%, respectively. In addition, there was no significant difference between drug groups according to bone metabolism markers, vitamin D levels, and osteopenia-osteoporosis rates. Assuming bone health will be affected at an early age in epilepsy patients, providing lifestyle and diet recommendations, avoiding polytherapy including VPA and CBZ when possible, and evaluating bone metabolism at regular intervals are actions that should be applied in routine practice.

[Evaluation of quality of life following treatment with calcitonin nasal spray in patients with osteoporosis: preliminary results of the MERLIN study]

BORS Katalin, KÓSA József, BORBÉLY Judit, TABÁK Ádám, HORVÁTH CSABA

[INTRODUCTION - MERLIN (Management of Osteoporosis in Elderly with Calcitonin) is an open-label, multicenter, prospective, follow-up study conducted in Hungary, part of which is to assess the impact of treatment with Miacalcic, - an intranasal salmon calcitonin, on the quality of life (QoL) among patients with osteoporosis. In this paper we report the preliminary results of the MERLIN study. PATIENTS - The study initially involved 1949 senior patients (aged >65 years) to whom calcitonin was prescribed for osteoporosis according to the application instructions. Patients presented at outpatient clinics and consisted of two groups; they were either newly diagnosed or they had been receiving a therapy for osteoporosis other than calcitonin. METHODS - This latter group discontinued their previous treatment and all patients received 200 IU intranasal salmon calcitonin (SCT) once daily for three months. Patient and physician questionnaires were used to collect information on the patients' QoL (EQ-5D VAS) and their general well-being at baseline and at follow-up visits at week 4 and week 12. RESULTS - Calcitonin use was associated with improvements in all EQ-5D domains and component scores as well as in VAS. Patients with previously known osteoporosis who, switched to calcitonin therapy achieved better results (0,046 QALY), than the newly diagnosed patients (0,0405 QALY). CONCLUSIONS - We conclude that intranasal SCT 200 IU daily is safe and effective in improving QoL of both, male and female patients with low bone mineral density.The conclusions that can be drawn from this study are limited due to the lack of a control group and to the unblinded design. Further placebo-controlled studies are needed to confirm these results. Nevertheless, our study was the first in Hungary to evaluate the quality of life impact of an osteoporosis treatment, and hopefully it will be followed by more such studies directed to other osteoporosis treatments.]

[Evaluation of arterial stiffness in children. Guidelines for the practice]

CSEPREKÁL Orsolya, KIS Éva, SZABÓ J. Attila, REUSZ György

[Assessment of early atherosclerosis and decreased arterial elasticity to recognise the cardiovascular dysfunction in high-risk patients has gained importance in the past decade. Since 1990, more than 630 papers have been published in the adult and pediatric literature. Methods of early risk assessment in adults are well determined in international recommendations. The aim of the present work is to review the suggestions of the American Heart Association helping us to find the most appropriate method for the non invasive methods of cardiovascular assessment of young adults and children. Furthermore, multicentric studies should be conducted to create a Framingham like score system for pediatric patients, to render cardiovascular risk assessment much easier for the every day routine.]

[Bone metabolism and body mass index in postmenopausal women]

TÁRCZY Csaba, TOLDY Erzsébet, SZERB János, VARGA László

[INTRODUCTION - In addition to several other causes constitutional factors play an important role in the development of osteoporosis.Various aspects of bone metabolism were examined to explain the differences in bone density between women with low and high body mass index (BMI). PATIENTS AND METHOD - One hundred and ninetytwo postmenopausal women were included in the study. Bone density was measured by forearm densitometry.To assess bone formation, serum osteocalcin levels were measured, while the rate of bone absorption was estimated from C-terminal telopeptide levels of collagen type I measured in urine and blood. RESULTS - The prevalence of osteoporosis was higher in women with low BMI than in those with normal or higher BMI. Bone metabolism - both formation and absorption - was increased in both groups, however, in women with low BMI this increase was more pronounced and bone metabolism tended to be shifted to absorption compared to patients with normal or higher BMI. CONCLUSION - Postmenopausal lean women have accelerated bone metabolism compared to obese women. This fact and the shift to absorption may be the main reasons for the higher frequency of osteoporosis found by densitometry in women with low BMI than in those with higher BMI.]
