[Forgotten agent: raloxifene]

BENKŐ Ágota

[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.]

[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.]

[Vitamin D receptor gene BsmI polymorphism in rheumatoid arthritis and associated osteoporosis - Experimental data]

RASS Péter és munkatársai

[AIM: Rheumatoid arthritis (RA) is commonly associated with secondary osteoporosis.The BsmI polymorphism of the vitamin D receptor (VDR) gene has been implicated in the pathogenesis of osteoporosis. However, little data is available on the relationship between rheumatoid arthritis and the BsmI polymorphism. In this study, Hungarian frequencies of BsmI polymorphism genotypes were compared with those found in other countries. METHODS: In this study, 64 RA patients and 40 healthy controls were tested for VDR gene BsmI polymorphism genotypes.The frequencies of the B and b alleles were correlated with densitometric and laboratory markers of bone metabolism as well as with laboratory markers of arthritis. RESULTS: Among control subjects, the frequency of the BB genotype (27,5%) was relatively higher than in other European populations. In RA patients with secondary osteopenia/osteoporosis the BB genotype was rarer, while the bb was more common than in control subjects. Markers of bone metabolism showed that the presence of the B allele in RA patients was associated with a lower bone mineral density and an increased bone loss, while the bb genotype was associated with a higher bone mineral content. An increased osteoclast and osteoblast activity was observed in patients with the B allele, as determined by biochemical markers of bone metabolism. Rheumatoid factor titer, an important laboratory marker of disease progression in RA, was significantly higher in bb patients compared to patients carrying the B allele. CONCLUSION: Our data suggest that the imbalance in B and b allele expression may be involved in the pathogenesis of osteoporosis and perhaps of rheumatoid arthritis.]

[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.]

[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.]

[Epilepsy in the elderly]

NIKL János

[The incidence of epilepsy is higher among the elderly, the most rapidly growing segment of the population, than in any other age group. New-onset seizures in elderly patients are typically symptomatic or cryptogenic partial seizures that require long-term treatment. Epilepsy in the elderly is a frequently occuring pathology, differing in etiology, clinical presentation and prognosis from those of young people. Establishing the diagnosis of epilepsy in old age can be more difficult than in younger patients due to the extensive range of differential diagnoses and a higher prevalence of concomitant disease. Beyond a certain age physiological and pathophysiological changes can affect the pharmacokinetics and pharmacodynamics of antiepileptic drugs(AEDs), increasing the risk of pharmacological interactions due to polypharmacy. Furthermore, the elderly people are sensitive to advers events of AEDs, as for example, to cognitive disturbances, osteoporosis. Several of newer AEDs have good safety and cognitive effect profiles and have no interactions with other drugs. The treatment strategies are demanding: they must take into consideration the co-morbidity, co-medication, alterations in drug metabolism, and the effects on aging body. These factors make the management of epilepsy in the elderly particulary challenging, but with appropiate pharmacological treatment most elderly people with epilepsy will remain seizurefree.]
