LAM KID - 2012;2(02)

[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.]

[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.]

[Practical questions regarding the use of teriparatide]

TAKÁCS István

[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.]

[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.]

[Efficiency and safety of the vaccination against H1N1 influenza virus in inflammatory bowel disease]

FARKAS Klaudia, JANKOVICS István, MELLES Márta, NAGY Ferenc, SZEPES Zoltán, WITTMANN Tibor, MOLNÁR Tamás

[INTRODUCTION - Inactivated influenza and H1N1 vaccination is recommended yearly for patients with inflammatory bowel disease receiving immunosuppressive therapy; however, immunomodulator and biological therapy might impair the immune response to the vaccination. In our study, we assessed whether immunity can develop in response to H1N1 influenza vaccination in patients receiving immunomodulator and/or biological therapy. We also assessed the occurrence of side effects after the immunisation in these patients. PATIENTS AND METHODS - In our prospective study, blood samples were obtained from 24 patients (12 Crohn’sdisease, 12 ulcerative colitis) one month after immunisation against influenza A/California/ 07/2009 (H1N1) virus. At the time of vaccination, all patients have been receiving immunomodulator and/or biological therapy for at least three month. Antiviral antibodies were detected by using microneutralisation assay. The safety of the vaccination was assessed by questionnaires. RESULTS - Every patient developed complete immunity against influenza A (H1N1) virus, independently from the type of immunosuppressive therapy. Regarding side effects, local symptoms occurred in six patients and systemic symptoms in another six patients. Mild diarrhea occurred in five patients. Moderate exacerbation of the disease was observed in 2 patients with Crohn’s disease and in one patient with ulcerative colitis. CONCLUSIONS - According to our results, immunocompromised patients with IBD can be safely advised to receive the vaccination. In our study, all patients developed adequate immunity according to microneutralisation titers.]

[THE GENETICS OF INFLAMMATORY BOWEL DISEASE]

LAKATOS Péter László

[The pathogenesis of inflammatory bowel disease is only partly understood; various environmental and host factors (e.g., genetic, epithelial, immune and non-immune) are involved. It is a multifactorial polygenic disease probably with genetic heterogeneity; some genes confer susceptibility to IBD in general, while others specifically increase the risk of ulcerative colitis or Crohn's disease or affect location (localized or extensive) and/or behaviour (e.g., mild, severe, aggressive). This review presents recent advances in the genetics of inflammatory bowel disease including chromosome segments newly recognized to be involved in inflammatory bowel disease as well as the role of NOD2/CARD15, SLC22A4/A5 and DLG5. The increasing genetic information provides, for the time being, a better understanding of the pathogenesis of the disease thus setting a basis for potential targets for therapeutic intervention. In the future, however, genetics may also help in refining the diagnosis or predicting disease course.]
