[Calcium intake is considered the base therapy of osteoporosis treatment. It is known that in case of inadequate calcium intake, specific anti-osteoporotic drugs are inefficient. In the present study, we aimed to investigate the alimentary and supplementary calcium intake among Hungarian osteoporotic patients, using a nationwide representative survey. Patients with osteoporosis were enrolled in the study. We determined the total alimentary calcium intake and the average supplementary dose. In some cases, total calcium intake was lower than recommended, in other cases it was significantly higher than that. In some cases, bone density showed a positive correlation with calcium intake. Vitamin D supplementation complied with current recommendations.]

[The pathogenic and clinical significance of the RANK-RANKL-osteoprotegerin system in rheumatoid arthritis]

SZENTPÉTERY Ágnes, VÁNCSA Andrea, SZABÓ Zoltán, SZEKANECZ Zoltán

[Rheumatoid arthritis (RA) is characterised by increased local and generalised bone resorption, which manifests in the develoment of marginal erosions and generalised osteoporosis, respectively. An increasing number of data suggest that lymphocytes, proinflammatory cytokines and other mediators involved in inflammation contribute to arthritic bone resorption. Therefore, the term ‘osteoimmunology’ has also become widely used. In RA, Receptor Activator of Nuclear Factor kappa B (RANK) and its ligand (RANKL) play a crucial role in bone resorption. These proteins, which belong to the tumor necrosis factor a (TNF-a) receptor and TNF ligand superfamilies, respectively, activate osteoclasts while interacting with T cells, synovial fibroblasts and other cytokines (e.g. IL-1, IL-17), which results in bone resorption. Osteoprotegerin (OPG) is a decoy receptor that also belongs to the TNF receptor family and inhibits RANK-RANKL interactions. There is increased RANKL production and decreased OPG production in RA. The interaction of RANKL with IL-17 is particularly important. Regarding therapy, sulfasalazine, methotrexate and biological agents, especially TNF inhibitors suppress RANKL-mediated bone resorption and thus the development of joint erosions. RANKL-RANK interaction can be directly inhibited by recombinant OPG or anti-RANKL antibody (denosumab). Among these agents, denosumab gave promising results in experiments performed in animal models of arthritis. These were followed by a phase II human RA trial, which proved that denosumab decreased MRI erosion scores in RA.]

[The relationship of coronary heart disease and bone from a different point of view: is lumbar vertebral density a positive predictor of coronary heart disease in women?]

KISS József, BUDAY BARBARA, LITERÁTI-NAGY Botond, FALUKÖZI József, FOGARASSY György, APRÓ Dezső, VECSEI Istvánné, FÉK A. Attila, VERESS Gábor, KORÁNYI LÁSZLÓ

[BACKGROUND - A number of international data demonstrate the relationship between cardiovascular disease and bone density, osteoporosis and osteopenia. It is possible that bone formation/remodeling and vascular calcification are influenced by common pathogenetic factors (adipocytokines, inflammatory processes). Our aim was to assess this relationship among Hungarian patients. PATIENTS AND METHODS - We examined 82 patients (49 men and 33 women). The patients underwent a DEXA measurement and fasting blood sampling with full metabolic profiling within one month following an elective coronarography. Coronary state was characterised by the Gensini-score. RESULTS - Femur neck T-score values showed significant decreases in the CHD+ group (patients having at least one significant coronary stenosis), compared with the CHD- group (patients with no history of significant coronary stenosis) (-0.22 vs. -0.85, p<0.05) when the two genders were examined together. In women, lumbar BMD showed a significant positive correlation (r=+0.37, p=0.03), and the levels of adiponectin and HDL-cholesterol showed significant negative correlations (r=-0.311, p=0.04, és r=-0.38, p=0.03) with the Gensini-score. Neither the HOMA-index that characterises insulin resistance, nor the majority of conventional lipid and lipoprotein risk factors showed any association with the severity of coronary heart disease. CONCLUSION - On the basis of our results, the relationships between femur and lumbar regions and coronary heart disease are opposite in nature, which is probably explained by the different regulatory mechanisms in these two regions. Adiponectin may have an important role in the regulation of this relationship, which is independent of insulin resistance.]

[Osteonecrosis of the jaws: real and unreal scares]

VASZILKÓ Mihály

[Osteonecrosis caused by bisphosphonates has been known for a long time, but it is still not widely known. Some people overestimate the danger caused by this disease, whereas others underrate it. In this paper, we summerise data from the international literature and our experiences concerning 93 patients treated at our clinic. We discuss the already known details of the pathomechanism of this disease, its risk factors, the diagnostic methods, the specific stages of the disease and the treatment approaches. Considering the difficulties of treatment, we can't emphasise enough the importance of prevention, since the development of this complication can be minimised even in patients at risk with dental sanation before the bisphosphonate therapy and/or with further intervention performed with antibiotic preventive therapy. We must also point out the importance of early diagnosis and of directing these patients to the appropriate specialist units.]

[Localised and generalised osteoporosis in autoimmune polyarthritis]

TÓTH EDIT

[In this article, recent data are summarised on the osteoporosis occurring in autoimmune polyarthritis. Involvement of the bone in patients with autoimmune diseases occurs in two forms: localised (around inflamed joints) and generalised. Paraarticular osteoporosis has been known for a long time but new methods of bone measurements highlight the rate and cause of bone loss. Generalised skeletal changes in rheumatoid arthritis, in systemic lupus erythematosus and juvenile chronic arthritis have been proved by epidemiological studies. At present, there is no evidence supporting generalised bone loss in other chronic inflammatory diseases. Despite the fact that clinically apparent osteoporosis in autoimmune diseases is associated with severe health impairment and reduced survival rates, osteoporosis is still underdiagnosed and prophylactic strategies have yet to be found for this group of patients. These facts indicate calling specialists’ attention to the importance of osteoporosis in inflammatory diseases.]

[The risk factors of osteoporosis and osteoporotic fractures in Hungarian women: the results of the NOKK study]

MEZŐ Tibor, TABÁK Ádám, BHATTOA Harjit Pál, LAKATOS Péter

[INTRODUCTION - It is widely accepted from Western European and the US studies that race and geography significantly affect the risk for osteoporosis. Less is known about similar associations in Eastern European subjects. Our aim was to describe the risk factors for osteoporotic fractures and osteoporosis in a selected female population in a cross-sectional, multi-center study performed under the guidance of the Hungarian Society for osteoporosis and Osteoarthrology. MATERIAL AND METHOD - From 10 randomly selected regional osteoporosis centers, altogether 2602 women >18 years of age, referred with any osteoarthrological reason, participated. During their visit data on risk factors, blood pressure, anthropometry, and bone mineral density were collected. RESULTS - Using multiple regression we found that older age, lower diastolic blood pressure, family history of bone fracture, fall in previous year and lower T-score were independently related to fractures. Independent risk factors for femoral osteoporosis included older age, lower weight, family history of fracture, less physical activity, fall in the previous year and glucocorticoid treatment. DISCUSSION - Our study is the first large-scale epidemiological survey describing risk factors of osteoporosis and fractures in a Hungarian female population. Our data may suggest that lower diastolic blood pressure might be related to osteoporotic fractures.]

[We conducted a multicentre, prospective, single cross-sectional, 12-month, open-label study for the assessment of treatment satisfaction using TSQM (Treatment Satisfaction Questionnaire for Medication) for zoledronic acid therapy used in patients with osteoporosis, who suffered minor traumatic fractures. PATIENTS AND METHODS - In total 1736 patients from 94 centers completed the study and filled in the TSQM questionnaire at both visit 1 and visit 2. TSQM is suitable for measuring the patient’s satisfaction with a treatment, by evaluating side-effects, efficacy and convenience of the treatment and the patient’s overall satisfaction rated on a scale of 0 to 100. RESULTS - Patients included in the study previously received a mean of 1.58 other therapies for osteoporosis and their case history included a mean of 1.24 fractures. This real-life study demonstrated that even one year of zoledronate treatment significantly (p<0.0001) improved the satisfaction of patients regarding efficacy (a mean change from a score of 56.15 to 70.89) as well as the occurrence of side-effects on a TSQM score. Regarding the convenience of treatment, the mean score increased from 62.96 to 79.34 (p<0.0001), whereas the overall treatment satisfaction changed from 59.3 to 75.48 by visit 2 (p<0.0001). CONCLUSIONS - Our study demonstrated beneficial TSQM results associated with zoledronic acid treatment, which is a basic requirement for appropriate adherence as well. ]

[SECONDARY OSTEOPOROSIS IN GASTROINTESTINAL DISEASES]

FUSZEK Péter

[Gastrointestinal disease is often overlooked or simply forgotten as a cause of osteoporosis. In a number of gastrointestinal diseases, sometimes because of the medicines used for their treatment, malabsorption syndrome may occur. Malabsorption might lead to insufficient absorption of calcium, phosphate, magnesium, vitamin D, vitamin K and proteins, which can cause osteopenia, osteoporosis and osteomalacia. In this paper, we aim to review the gastroenterological diseases that can lead to osteoporosis and treatment strategies.]

[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.]
