LAM KID - 2012;2(03)

[This risk of osteoporosis-related fractures is influenced by a number of well-known risk factors. Among the approaches to quantify bone fracture risk, the FRAX questionnaire is the most widespread in everyday practice. However, this method only provides a probability percentage for the physician, and it is unable to specify or weigh the factors that may have a particular importance in evaluating individual fracture risk, or choosing the appropriate therapy in patients with previous osteoporotic fracture. This summary aims to provide practical help for the evaluation of individual fracture risk in patients who have had bone fractures.]

[Efficiency of osteoporosis treatment in Hungary - An analysis of the Hungarian National Insurance Company’s data]

LAKATOS Péter, TÓTH Emese, SZEKERES László, POÓR Gyula, HÉJJ Gábor, TAKÁCS István

[The treatment of osteoporosis and its consequences place a significant burden on the health care of developed countries. Modern therapeutical approaches are able to efficiently decrease the risk of osteoporotic bone fractures. However, we do not know whether the interventions introduced in the past 15 years have significantly reduced the number of osteoporotic fractures in real life, and if they have, how cost-effective this effect was. To answer these questions, we have analysed data of the Hungarian National Insurance Company collected between 2004-2010. During these 7 years, the number of bone fractures among patients treated for osteoporosis continuously decreased. This was also observed in the incidence of hip fractures. Interestingly, the mortality of osteoporotic patients was significantly lower than that of the same age group in the average population. Besides the efficient treatment of osteoporosis, this finding is also due to the outstanding general care provided by the specialised osteoporosis centers of the country. As a consequence of the reduction in fractures, 3.4 billion HUF was saved per year by the insurance company, which is approximately equal to the 3.5 billion HUF spent on the reimbursement of medicines used for the treatment of osteoporosis, which means that the investments show a return. The calculation of the quality- adjusted life years, which is the internationally accepted method of the WHO for the study of cost-effectiveness, shows that the above results were achieved in a remarkably cost-efficient way. At the same time, it is noteworthy and calls for caution that the decrease in reimbursement by the insurance company in 2007 resulted in a 51% drop in the number of patients receiving treatment, which radically reduced the observed efficiency.]

[The effect of nonsteroidal anti-inflammatory drugs on articular cartilage]

GÁTI Tamás, JUHÁSZ István, ROJKOVICH Bernadette

[In developed countries, the treatment of osteoarthritis costs up to 1-2% of the GNP. The poor hygroscopy of hyaline cartilage and of glycosaminoglycan (GAG) molecules that are components of proteoglycans plays a key role in the development of the disease. Age-related osteoarthritis mostly affects the weight-bearing joints of the lower extremities, the hips and knees, and - more frequently than the former ones - the small joints of the hands, causing chronic pain and disability. Nonsteroidal anti-inflammatory drugs (NSAIDs) used for the treatment of osteoarthritis-related pain influence not only pain but also cartilage metabolism, and - among others - GAG molecules. NSAIDs diminish the biosynthesis of prostaglandins (PG) that have a role in inflammatory processes, and influence oxygen free radicals, the levels of interleukins (ILs) and the function of metalloproteinases. The ideal NSAID for the joints stimulates cartilage formation, reduces cartilage resorption, and the level of katabolic cytokines. Aceclofenac was found to have the most beneficial effect on multiple aspects of cartilage metabolism.]

[Vitamin D deficiency and infections]

LUDWIG Endre, KRIVÁN Gergely

[Studies performed in the past few years have confirmed that vitamin D is essential for maintaining the optimal immune defense, and its immunomodulatory effect has a role in the defense against infections as well. A lot of data suggest that low serum 25-(OH)-D concentration is associated with an increased frequency of certain infections and it adversely influences pathological processes. Data on this adverse effect are available mostly in case of Mycobacterium tuberculosis, respiratory viral infections in general, HIV, hepatitis C and sepsis. The outcomes of severe infections are usually influenced by a number of factors and it seems that vitamin D deficiency is one of those factors that shift the process towards an unfavourable outcome. Further studies should evaluate the significance of this role and the influence of vitamin D supplementation on pathological processes.]

[Why twins are different? - About twin research]

ERDŐS Edina, BÁLINT Bálint László

[Twin studies had an important role in the development of medicine. In this review, we present the available data of Hungarian twin studies and the number of twins in Hungary on the basis of statistical data. Comparing these data with international ones and taking into account probable prevalences, we aim to provide an estimation of the number of twins in Hungary who have cancerous diseases. Our estimation suggests that creation of a national database for such twins is feasible and could provide a great help for a better understanding of the causes and mechanisms of cancerous diseases.]

[Association between osteoporosis and nutrition during the history of human evolution]

KISS Zoltán, KISS István, JÓZSA László

[From the Palaeolithic age to the twentieth century, nutritional habits as well as the quality and composition of nutritients changed dramatically. The protein-based calorie intake of former Homo species had been replaced by a carbohydrate-based nutrition since the Neolithic revolution (the transition to agriculture). The start of food production also changed the range of nutrients and the start of sedentary lifestyle. At the same time, approximately five thousand years ago osteoporosis appeared. In this paper, the authors give a short review of eating habits and foods of early Homo species in the Palaeolithic Age and of Homo sapiens in Neolithic Age, Antiquity, Middle Ages and Modern Age, and discuss the possible relationship of nutrition and osteoporosis.]

[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.

[New findings in the cortical bone biology and its role in bone fractures]

BALOGH Ádám, BHATTOA Harjit Pál

[The authors surveyed the already known factors responsible for the osteoporotic bone fragility. Then the results of using modern imaging techniques (micro-CT, high-resolution peripheral computed quantitative tomograph - HR-pQCT) and advanced computer analytic methods (finite element analysis, FEA) are presented. These data - beyond the already known fracture risk factors (age, risk of falling, bone mineral density - BMD, and fine structure damage of trabecular bone) are stressing the importance of the (micro)damage of cortical bone as a fracture risk factor, which has been still underrated. The cortical thickening and increased porosity - verified on various population samples - are increasing the risk of fractures in certain subgroups of subjects having identical BMD values, even among those, who are considered only osteopenic by the earlier classification based on BMD values. Backed with modern software batteries, the new imaging techniques are expected to enter clinical application in the near future. Pharmacologic agents with stronger cortical effect are already available and research is continuing to find new drugs to use in the management of osteoporotic patients of high fracture risk.]

[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.]

[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.]
