LAM KID - 2012;2(02)

[Teriparatide has become one of the most important drug in the treatment of osteoporosis in Hungary. Although this is not a new drug, a number of questions arise regarding its use in everyday practice. When should we use it as first-line treatment? When should we change the used therapy to teriparatide? What kind of effect can we expect after the start of teriparatide therapy? What are the potential side effects? Financing rules limit, but do not fully control our therapeutic decisions, as these are mostly based on scientific data. In this review, we summarise new and older scientific data regarding teriparatide from practical aspects.]

[Bone status in praediabetic state - Relationship of bone density and energy homeostasis before the manifestation of type 2 diabetes mellitus]

BUDAY BARBARA, VITAI Márta, PACH Péter, LITERÁTI Nagy Botond, PÉTERFAI Éva, BEZZEGH Katalin, PAUER József, KORÁNYI LÁSZLÓ

[INTRODUCTION - All forms of diabetes are associated with increased fracture risk. In type 2 diabetes, bone mineral density is increased. In order to determine whether increased bone density is a consequence of diabetes-related metabolic changes or rather a primary alteration independent of these changes, we examined women and men with the following characteristics: normal glucose tolerance; genetically determined risk of T2DM but healthy on the basis of detailed metabolic tests; or incipient glucose intolerance, praediabetic state. PATIENTS AND METHODS - We included 72 men with normal glucose tolerance; seven men with normal glucose tolerance and first-degree relative(s) with diabetes; 64 body fat mass adjusted and BMI-adjusted men with glucose intolerance; 36 healthy women with normal glucose tolerance; 12 women with normal glucose tolerance and first-degree relative(s) with T2DM and 88 women with glucose intolerance. Muscle glucose uptake was measured by hyperinsulinaemic-normoglycaemic clamp, and bone density was measured by DEXA. RESULTS - In healthy men, the connection between leptin and BMDL1-4 is positive and the relationship between testosterone and BMDL1-4 is negative, but both correlations disappear in the early praediabetic stage. In the whole female study population, negative correlations were found between total BMD and adiponectin (r=-0.318, p<0.0001), and osteocalcin (r=-0.412, p<0.0000), which stayed significant after adjustments for body fat percent and age in case of impaired glucose tolerance. CONCLUSION - In women with healthy glucose metabolism who have first-degree relative(s) with diabetes, increased bone density is not related to changes in glucose metabolism. Our study emphasizes the substantial gender differences in the relationship between density of the femur and vertebrae and metabolism. Our data question the mediatory role of adiponectin shown in animal studies in the insulin-sensitizing, glucose metabolism improving effect of osteocalcin in men.]

[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.]

[Novelties in the management of Hodgkin lymphoma]

ILLÉS Árpád, MOLNÁR Zsuzsa, MILTÉNYI Zsófia

[Hodgkin lymphoma is a lymphoproliferativ disease, it is about 12-18% of all lymphomas. It has typical morphologic, clinical and therapeutic features, which can distinguish from other lymphoma types. Due to risk- and PET/CT adapted treatment Hodgkin lymphoma is a curable lymphoma with an 80-90% long-term survival, however, refracter- and relapsed patients’ therapy is a great challange. Cure rate can increase due to the development of the diagnostic and treatment modalities, but the use of standard recommendation is necessary. The aim of this review is to show new WHO 2016 lymphoma classifi cation, role of the new diagnostic options, especially 18FDG-PET/CT, Lugano classifi cation and fi rst-line and salvage therapeutic possibilities and to introduce the immunotherapy, like brentuximab vedotin and PD1 inhibitors. Certain points of hemopoietic stem cell transplantation will be also covered.]

[PREVALENCE OF OSTEOPOROSIS IN PATIENTS WITH COLLES’ FRACTURE]

NAGY József, BÁLINT Géza, TAKÁCS Katalin, WINKLER Valéria, RATKÓ István, BÁLINT Péter

[INTRODUCTION - Studies suggest that Colles’ fracture is the earliest of the osteoporotic fractures, and thus may be the first indication of the disease. PATIENTS AND METHODS - Fifty-seven consecutive patients with Colles’ fracture who presented between 1st of October 2003 and 1st of February 2004 at the traumatology out-patient clinic of Semmelweis Hospital, Kiskunhalas were screened for osteoporosis. RESULTS - Of the 43 postmenopausal women, 41 was found to have osteoporosis by DEXA scan, but only one was aware of her disease and received treatment. Out of these 41 patients 15 had fractures previously, 9 of whom had more than one. None of the four premenopausal women had osteoporotic DEXA measurement values. All of the 10 male patients had osteoporosis, 6 had previous fractures, 5 of them more then once. One patient required surgery, there was a prolonged fracture healing in 10 cases, and reflex sympathetic dystrophy developed in 3 patients. CONCLUSION - Since in this study more than 95% of postmenopausal women with Colles’ fracture had underlying osteoporosis, the authors conclude that DEXA scanning of these patients is recommended. Based on the results, it seems that screening for osteoporosis is indicated for both men and women after radius fracture.]

[VITAMIN D TREATMENT: HORMONE THERAPY FOR PATIENTS WHO NEED IT OR SIMPLY A SUPPLEMENTATION FOR EVERYONE?]

SPEER Gábor

[Various medical associations issue different recommendations for the prevention and treatment of vitamin D deficiency. These significant differences are partly explained by the different definition of normal vitamin D level and the use of completely different mathematical models to predict the increase in vitamin D level as a response to therapy. According to the Institute of Medicine (IOM), the target vitamin D level is 20 ng/ml, whereas the Endocrine Society (ES) recommends 30 ng/m as the miminum target value. According to the ES, a 1 ng/ml increase of vitamin D level can be reached by a daily intake of 100 NE, while the IOM recommends 3.6 ng/ml. Moreover, the IOM states that the effect of therapy on serum level is nonlinear. These differences show that the ES and IOM have different views on the risk of adverse effects. The IOM recommends 400 IU vitamin D daily for children younger than 1 year, 800 IU for those above 70 years and 600 IU/per day for everyone else. The ES recommend 400-1000 IU daily for all infants and 1500- 2000 IU for adults. Screening, however, is not recommended by either society. To decrease uncertainty concerning the side effects of higher-dose vitamin D treatment, it is important to understand, use and support the function of the pharmacovigilance system of the pharmaceutical industry that manufactures and markets various (prescription, over-the-counter) preparations. This is what the author aims to highlight in the second part of this article. Using this system, both the doctor and the patient can help support and accept the justification of higher-dose vitamin D therapy.]

[Osteoporotic patient’s use of prescription drugs - pilot study]

BATKA Gábor, SZENTANDRÁSSY Andrea Éva, SZEKERES László

[BACKGROUND - In Hungary, the number of the highest mortality hip fractures is between 12 000-15 000 per year. The cost of treating hip fractures is several times higher than that of preventive medical therapy. Thus, the compliance of patients with osteoporosis is of great importance. METHODS - Using the informatical database of St. András Rheumatology Hospital at Héviz, we collected one year’s prescription drugs for osteoporosis and compared them with the number of drugs obtained by the patients, determined from National Health Insurance data. RESULTS - In general, the patients obtained 75% of prescription drugs. From the 4354 boxes of prescribed antiporotics, 3637 contained bisphosphonate (not considering vitamin D and calcium). Within this group, 88% of combination preparations were obtained, which is a greater ratio than that of non-combination bisphosphonates (84%). CONCLUSIONS - On the basis of our results, we posit that prescription of a combination preparation somewhat improves the patients’ compliance. The low concordance of vitamin D and calcium preparations is worrying.]
