[Among fractures attributable to osteoporosis, hip fractures are associated with the most severe consequences and the greatest costs. Surgical therapy for this condition is continuing to improve. Increasingly recent implants and techniques are being developed and introduced to successfully control postoperative adverse events. The authors briefly outline actual practice in Hungary and present some results of the follow-up of their patients in the last decade. These show that, in order to improve outcomes of hip fracture patients, all domains of management need to be addressed.]

[RANKL-specific denosumab in the treatment of osteoporosis - Possible adverse effects of long-term use]

TANKÓ László

[According to the results of a recent clinical trial, the antiresorptive effect of a single 60-mg injection of denosumab, a monoclonal antibody specific to RANKL (receptor activator of NFκB ligand) substantially exceeds the effect of alendronate (70 mg weekly). Despite these differences, 1-year increases in bone density at the lumbar spine are virtually identical for both agents. The author summarizes experimental and clinical observations illustrating potential consequences of osteoclast deficiency and a constantly low rate of bone resorption for osteoblast function, bone mineralization, bone quality parameters, and mechanical properties, which all may have important implications for bone fragility. These observations also raise the question whether treatment efficiency is truly improved by aggressively pushing the limits of antiresorptive action.]

[Denosumab - pharmacokinetic and clinical evidences]

MÉSZÁROS SZILVIA

[Denosumab is a fully human monoclonal antibody to RANKL modifying bone resorption in a rapid, sustained and reversible way. In postmenopausal women with low bone mineral density, denosumab 60 mg every 6 months increased mineral density, and reduced bone turnover. In postmenopausal women, it reduced the risk of vertebral, hip, and non-vertebral fractures. Increase in body mass index and reduction in bone turnover was more pronounced with denosumab than with alendronate. In patients who were switched from alendronate to denosumab, positive effects on bone were more pronounced than in those continuing alendronate. Denosumab was safe and well tolerated, and it holds the promise of becoming an efficacious therapy for postmenopausal osteoporosis.]

[Rehabilitation of patients with osteoporotic bone fractures]

BORS Katalin

[Consequences of osteoporotic bone fractures are increased mortality, decreased quality of life, and increased direct and indirect costs. After the assessment of remaining function and the level of independence, the goal of rehabilitation is to reach the highest level of function and independence possible, thus decreasing morbidity and mortality, improving the overall quality of life, and decreasing costs.]

[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.]

[Bone mineral density and diabetes mellitus - First results]

TÕKE Judit, TAMÁS GYULA, STELLA Péter, NAGY Erzsébet, NÁDASDI Ágnes, VARGA Piroska, KERÉNYI ZSUZSA

[INTRODUCTION - Data on bone mineral density (BMD) in diabetes mellitus are contradictory in the literature. Early studies described a decreased bone mineral density in type 1 diabetes mellitus (T1DM), but recent studies report no osteopenia in T1DM.The BMD may depend on the quality of treatment for diabetes mellitus and on the presence of chronic complications. In type 2 diabetes mellitus (T2DM) the BMD is not decreased, occasionally it can even be increased. PATIENTS AND METHODS - Bone mineral density was measured in 122 regularly controlled diabetic patients (T1DM: n=73, mean age: 43.6±11.1 years,T2DM: n=49, mean age: 61.8±9.8 years) by dual energy X-ray absorptiometry at the lumbar spine and at the femur. Results were compared to those of 40 metabolically healthy control persons with a mean age of 47.5±11.9 years.The patients’ carbohydrate metabolism was assessed by the average HbA1c level of the last three years.These values were 7.9±1.4 % in T1DM, and 7.5±1.7 % in T2DM. BMDs were classified based on the T-score and Z-score using the WHO criteria. RESULTS - There was no significant difference in T1DM or in T2DM compared to the reference group in the prevalence of either osteoporosis or of osteoporosis and osteopenia combined. CONCLUSION - BMD was not found to be decreased in patients with well-controlled metabolism compared to healthy controls.]

[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. ]

[Once again on adherence - Is it just fashionable or indeed a timely issue?]

VALKUSZ Zsuzsanna

[Nonadherence to pharmacological treat-ment in osteoporosis is a well-recognised problem not only in Hungary but all over the world. As in other chronic diseases, adherence to osteoporosis treatment is poor, which results in serious problems affecting patients as well as health care resources. Low adherence rates consistent-ly result in increased rates of fractures. Some approaches aimed to improve com-plience and persistence, such as extension of dosing intervals, might improve patients’ adherence to therapy. International clinical studies have demonstrated that the number of fractures cannot be reduced without suf-ficient adherence. Improving patient edu-cation, enhancing interactions between health care providers and patients, taking into account patients’ preferences and involving them in treatment decisions may all improve adherence.]
