[Forgotten agent: raloxifene]


[The largest group of the patients with osteoporosis is postmenopausal women characterized by a state of menopausal hormone deficiency which is results in accelerated bone loss. This increased bone resorption significantly elevates the risk of bone fractures including the most common type, i.e. vertebral fractures. In addition to the increased risk of fractures, estrogen deficiency affects other organs, thus, increasing the incidence of cardiovascular diseases, cancers, mood disorders and the symptoms of menopausal syndrome in women after menopause. In postmenopausal osteoporosis, the primary objective is to maintain the existing bone mass, a priority for the prevention and treatment of bone fractures. Hormone deficiency may be prevented by the administration of estrogen but the treatment may have adverse effects such as increased risk of endometrial cancer. An etiological therapy is desirable where the compound used for treatment exerts effects similar to that of estrogen to prevent postmenopausal bone loss as well as reduces the risk of cardiovascular disease without the stimulation of reproductive tissues.]


[Investigation of vitamin D supply in hospitalized patients]


[Recent studies have shown that adequate vitamin D level is essential in the maintenance of normal immunological status and presumably, it has a remarkable role even in the healing of some diseases. Vitamin D deficiency is a common phenomenon worldwide. Presently, the accepted marker of vitamin-D status is the total-25-hydroxy- D-vitamin [t-25(OH)D], its level depends on the specific (DBP) and aspecific (albumin) binding proteins. As known, the level of binding proteins may change in the hospitalised patients therefore, the presently used marker could not be reliable for the vitamin status in these cases. Our aim was to measure the D-vitamin supply among hospitalized patients, taking into account the level of binding proteins. METHODS - 401 cases (average age 70±14 years) were sorted from Internal Medicine (IM; 68), Intensiv Care Unit (ICU; 58), Traumatology (203 patients suffered hip fracture) and Dialysis Center (72 patients with end stage renal disease). 127 age and sex matched persons with active lifestyle served as control group. We determined t-25(OH)D, DBP, parathormon (PTHi), albumin and the albumin corrected Ca level. The bioavailable and free vitamin fractions and the free index were calculated. RESULTS - Based on the measured t- 25(OH)D, patients have more frequently suboptimal D-vitamin levels, compared to the control group (66% vs. 97%). Severe Dvitamin deficiency occured nearly 8 times more likely (6% vs. 47%) in the hospitalized patients. Chronic renal failure and malignant diseases seem to be significantly negative influencing factors in the metabolism of the vitamin D. The level of DBP, albumin, t-25(OH)D, Bio-25(OH)D was significantly lower in the patients who died. CONCLUSION - In most cases, t-25(OH)D levels show similar results about the vitamin- D supply than other calculated 25(OH)D fraction ,except for the patients of ICU and IM . The t-25(OH)D, the Bio- 25(OH)D, the DBP and the albumin levels seem to be a good prognostic marker of the outcome.]


[Role of patient clubs in successful treatment of osteoporotic patients]

SOMOGYI Péter, GAÁL János, SPEER Gábor

[The significance of osteoporosis is well known, however, the number of patients receiving treatment is only a small fraction of ideal. Besides, the fact that the population is uninformed, the difficulties of making an appointment with a specialist and the unsatisfactory communication of the doctor all play a part in the fact that a high proportion of patients receiving mediation give up treatment prematurely. The Inter - na tional Osteoporosis Foundation supports the establishment of public patient clubs with regular training courses and grants and by doing so it also acknowledges their importance in the prevention and treatment of osteoporosis. The publication, based on the questionnaire filled in by the members of the first Hungarian patient club, the Hungarian Society of Osteopo - rosis Patients in district 3rd, introduces the Hungarian results and points out how important patient clubs are in increasing the success of treatment and it also draws attention to the necessity of establishing further patient clubs in the future.]

[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.

[A new approach to renal osteodystrophy in the diagnosis and treatment of]

MÁCSAI Emília, SZLOVÁK Edina, DOLGOS Szilveszter

[Treatment of renal osteodystrophy (ROD) is one of the new osteoporosis recommendations requires a rethink of the current therapeutic approach. Addressing vitamin D deficiency and reducing quality of life deterioration caused by bone fractures it is also an important professional challenge in the renal insufficiency population. ROD is a classic nephrological treatment to improve the results of the newer molecular expected from better understanding of pathomechanisms and better imaging methods. Associated associations with vascular calcification are cardiovascular can help our efforts to prevent complications, a relationship with periodontal disease the importance of regular monitoring supports. In addition to phosphorus binders, vitamin D agonists and calcimimetics in the future is expected to be the resorption inhibitor denosumab, the bone-building processes supporting PTH analogues and the wider clinical use of romosozumab application.]


[Quality of life of patients with osteoporosis in Hungary]

VOKÓ Zoltán, INOTAI András, HORVÁTH CSABA, BORS Katalin, SPEER Gábor, KALÓ Zoltán

[AIM - The aim of our study was to estimate the loss of quality of life due to osteoporotic fractures. We performed a cross-sectional study including 840 patients in 21 centers that specialise in the care of patients with osteoporosis and in acute care of fractures. METHODS - Patients were selected randomly and stratified for the location of and time elapsed since the fracture. Quality of life (QoL) was assessed by the Qualeffo-41 and the EuroQol-5D questionnaires. RESULTS - Patients with morphometric fractures of more than one vertebra had the lowest median EQ-5D index value (0.59). Symptomatic vertebral, hip and arm fractures also considerably decreased QoL. Patients with morphometric fractures of more than one vertebra had the lowest total Qualeffo-41 score. When controlled for age and gender, patients with hip fracture or morphometric vertebral fracture had at least 0.2 less mean utility values than had osteoporotic patients without history of fracture. Patients with more than a oneyear history of hip fracture had QoL scores as low as had patients with an acute fracture. In case of wrist and arm fractures, the acute loss of QoL somewhat decreased with time. CONCLUSION - In conclusion, osteoporotic fractures, especially hip and vertebral fractures result in a significant loss of patients’ quality of life. Our results show that physicians need to pay a close attention to morphometric vertebral fractures, which contribute to a great loss of human capital.]
