[The role of bone turnover markers in the diagnosis and therapy of osteoporosis]


MARCH 30, 2013

LAM KID - 2013;3(01)

[Osteoporosis is a metabolic bone diseasecharacterised by decreased bone mass andimpaired bone turnover, which leads to anincreased risk of fractures and significantmorbidity and mortality. Its social and pub-lic health impact and the importance of itsearly and accurate diagnosis are indis-putable. The aim of timely and efficienttherapy is to improve bone quality as wellas to prevent the dreaded complications ofbone fractures. In clinical practice, labora-tory diagnosis of biochemical bone mark-ers are particularly important for therapeu-tic monitoring. In this article, reviewing lit-erature data, we discuss bone-specificmarkers from the clinician’s perspective,and highlight their importance in everydayclinical practice. ]

[A dogma of histochemistry that seems to be refuted - histological detectability of urate crystals]

BÉLY Miklós, KRUTSAY Miklós

[In medical practice there are a number of “truths etched in stone” that are passed on from textbook to textbook and learned by generations before they become obsolete. This short study aims to eliminate a misbelief from the diagnosis of gout that is related to the histological detectability of urate deposits. According to the generally accepted thesis, urate crystals obtained from patients with gout are dissolved in formalin solution, therefore, tissue samples should be fixated in alcohol. The authors have found that urate crystals can be detected on conventionally mounted, native (unstained) sections, despite formalin fixation, whereas the great majority of urate crystals are dissolved during haematoxylin-eosin staining. Therefore, for the detection of urate crystals the tissue samples should be examined on native, unstained sections.]

[Osseal and extraosseal effects of vitamin D]

GAÁL János

[The author reviews the literature on the osseal and extraosseal effects of vitamin D, discussing the role of vitamin D sufficiency in the maintenance of normal bone structure and bone mass, in fracture prevention and in the efficacy on antiporotic treatment. The effects of vitamin D on hemopoiesis, tumours, muscles, articular cartilage, lungs, cardiovascular system, central nervous system, skin and certain metabolic disorders are also discussed. The paper particularly emphasises and describes on a cellular level the immune-modulating effect of vitamin D and its influence on autoimmune disorders.]

[Osteoporosis poses a major public health problem worldwide due to the extreme number of patients and to the deterioration of quality of life, disability, excess mortality and costs associated with consequent fractures. Representative studies of the author’s group have previously shown that the average bone mineral density values of the Hungarian population are among the lowest in Europe while the prevalence of vertebral fractures is among the highest in international comparison. This revelation has led to the development of a National Osteoporosis Programme, the key element of which being the setting up of a network of osteoporosis centres that are based on the collaboration of various medical specialists, the availability of advanced diagnostic tools and outstanding therapeutic opportunities. On describing the 10-year activity of the centres, the main diagnostic, prevention and management approaches of osteoporosis are discussed. According to the WHO classification the diagnosis of osteoporosis is based on a low bone mineral density finding supported by the laboratory and radiological exclusion of other metabolic bone diseases and secondary forms of osteoporosis. According to the up-to-date treatment guidelines of osteoporosis, when considering medical treatment, preference should be given to patients with high fracture risk in giving drugs with extensive antifracture efficacy that has been confirmed by studies of evidencebased medicine. Among these drugs the most important are the antiresorptive bisphosphonates that have widely been used in Hungary and the bone forming teriparatide that is expected to gain wider use in the near future with the introduction of public health insurance financing. The efficacy of these specific antiosteoporotics is increased by supplementation with calcium and vitamin D. The internationally acknowledged Hungarian osteoporosis management system offers to Hungarian patients outstanding standards for the prevention and management of osteoporosis.]

[Percutaneous procedure for treatment of diseased vertebral bodies with different etiology: vertebroplasty]


[Percutaneous vertebroplasty is a radiologically guided invasive technique consisting of the injection of surgical cement into the diseased vertebral body. The procedure results in immediate pain relief and strengthening of the bone due to the polymerization process of the filling material hardening the vertebral body and preventing further collapse. This method is suitable for the treatment of osteoporotic vertebral fractures and of osteolytic vertebral body metastases without neurological signs, in multiple appearance as well. Authors present technical details of the procedure performed by bi-directional fluoroscopy and combined CT-fluoroscopy control as well as short-term experience obtained by treatment of 17 patients.]


[A magnézium és csonthatásai]


[Since 1932, a number of animal studies have demonstrated the correlation of hypomagnesaemia and hypocalcaemia, and the variety of skeletal abnormalities resulting from low magnesium (Mg) intake. Several studies have shown that patients with osteoporosis have a decreased serum magnesium level, which is related to decreased bone mineral content and increased bone fragility. Mg has multiple physiological effects, thus it is not surprising that dozens of hypomagnesaemia-related diseases and symptoms have been reported. Adequate Mg concentration is necessary for the secretion of parathormone and its effect on target organs, activation of vitamin D in the kidney, the maintenance of calcium homeostasis, bone mineralisation and regeneration. Mild hypomagnesaemia is associated with general, atypical symptoms, whereas severe Mg deficiency is a life-threatening condition. Its concentration should be measured in serum and urine. Mg metabolism is determined by its absorption from the intestines and reabsorption in the kidneys. Recently revealed details of these processes give some insights into the mechanisms underlying a number of Mg deficient conditions related to genetic or medical reasons. Mg supplementation may be indicated for patient populations with the highest risk of hypomagnesaemia. For supplementation, the recommended total Mg dose is 350 mg, first in higher doses, several times per day for a longer period, complemented with Ca and K supplementation. Overdosing can only occur in patients with impaired renal function, which necessitates careful monitoring. Adequate Mg supplementation is an inexpensive, safe and effective preventive and therapeutic option for many diseases.]


[Adherence of Hungarian postmenopausal women with osteoporosis]

LAKATOS Péter, TÓTH Emese, LANG Zsolt, NAGY Bence, SZEKERES László, TAKÁCS István

[INTRODUCTION - Osteoporosis is defined as a loss of bone tissue and bone mass that leads to a compromised trength and quality of bones and thus to an increased risk of fractures. In many women, menopausal hormonal changes are associated with an increased bone loss. This population has postmenopausal osteoporosis. The essence of osteporosis treatment is the adequate calcium and vitamin D supplementation, which, if needed, might be combined with drug therapy to inhibit the process of bone loss. METHODS - We assessed the adherence to therapy of Hungarian patients and its effect on the risk of bone fractures, using data recorded by the National Health Insurance Fund Administration between 2004 and 2010 (n=223068, mean age: 69.9 years). We performed a statistical analyses of the available data. Medication possession ratio (MPR) for each treatment and the ratio of patients receiving continuous treatment in the study period (for 12, 18 and 24 months) were estimated. Medication persistence was investigated using Kaplan-Meier survival analysis. A multivariate Cox proportional hazard model was used to determine the factors influencing the risk of fracture. RESULTS, CONCLUSION - The results of our study show that medication adherence to treatment is low among Hungarian patients [mean MPR: 57.9%; 95% CI (57.7%- 58.0%) and persistence rate: 32.4%; 95% CI (32.2%-32.6%) in the first year]. These parameters are substantially influenced by the administration route and the frequency of treatments [mean MPR ranged 41.5%- 100% and persistence rates ranged 18.8%- 100% in the first year, differences between subgroups were significant (p<0,05)]. Our compliance as well as persistance studies showed that parenteral administration had more beneficial effects. Confirming our preliminary hypotheses, the improvement of patient compliance significantly reduced fracture risk (good compliance was defined as MPR>80%, which was associated with RR: 0.57, p<0.05 for fracture risk). Further improvement might be achieved by parenteral administration [RR for fracture risk 0.60 compared with non-compliant patients and 0.44 compared with compliant subgroups treated with oral and parenteral medications (p<0.05)].]


[MOOT-COMP study - Compliance of patients with antiporotic treatment]

BORS Katalin, BOROS Erzsébet

[INTRODUCTION - Several studies prove the importance of the lack of compliance in the ineffectiveness of drugs which have been tested by clinical studies. In our study we finded the reasons of leaving off the antiporotic treatment. PATIENTS AND METHODS - 1067 osteoporotic patients (91% women, 9% men) were enrolled to examine compliance and to find explanation of non-compliance. We asked the patients about medications, exercises, electrotherapy and medical aids. RESULTS - Medications were recommended for most patients and exercise was the secondary most common therapeutic method. Electrotherapy was prescribed for one third and medical aids were recommended for one fifth of the recruited patients. Two third of patients reported to take all pills, most of them suffered from bone fracture. More than one fifth of patients sometimes or often forgot to take the treatment. 10% more patients did exercises than it was recommended by the practitioner. However, only 25% of all patients did exercises appropriate frequency and at least 20 minutes per day. Electrotherapy was not prescribed by the doctors for more than half of patients on this treatment. Medical aids were not used by 10% of patients despite the recommendations. Almost one third of the enrolled patients reported a fact which disturbed keeping recommendations of the doctors. These facts were financial problems, long waiting lists and low motivation of patients for keeping recommendations. The compliance did not correlate with education and social status. The patients with multiple fractures were more comply with medications and exercises. CONCLUSION - Drawing the informed patient into decision making and knowing the therapeutic outcome are important factors for keeping therapeutic recommendations. The high fracture rate in Hungary attracts our attention for enhance patient compliance.]
