[Higher bone fracture prevalence in postmenopausal pollen allergic women]


FEBRUARY 14, 2007

Ca&Bone - 2007;10(01)

[Our aim was to investigate whether pollen allergy can affect bone mass and fractures in postmenopausal women. A total of 125 postmenopausal pollen allergic women (mean age 61.26 years) were split into four groups: treated neither with H1 histamine receptor (H1R) antagonist nor with inhaled corticosteroid (n=43), treated only with H1R antagonist (n=53), treated both with H1R antagonist and inhaled corticosteroid (n=17), treated only with inhaled corticosteroid (n=12) for at least five years, seasonally. One-hundred non-allergic postmenopausal subjects matched for age, body mass index (BMI) and age at menopause served as controls. Overweight and obesity (25 kg/m2 ≤ BMI) were common among allergic women (76%). Allergic patients without treatment had a slightly lower bone density than their non-allergic mates. Untreated allergic had almost triple the rate of prevalent low-energy fractures (distal forearm, hip and clinical vertebral fractures: 34.9%) compared to non-allergic women (13%, χ2 p=0.003). Bone fracture occurred more often in H1R-only treated patients (30.19%) than in controls (χ2 p=0.01), however, clinical vertebral or hip fractures developed neither in those treated only with H1R antagonist nor in those who received both H1R antagonist and inhaled corticosteroid. Bone fractures were more frequent among patients with inhaled steroid treatment than among patients with a combined treatment of inhaled steroid and antihistamine (50% vs. 29.4%). BMI predicted prevalent fractures at 1.278 (95% CI, 1.047 to 1.559, p=0.016) for 1 kg/m2 increase among untreated allergic patients. In conclusion we found a high prevalence of low-energy fractures among pollen-allergic postmenopausal women, which was associated with obesity. It is possible that the H1R antagonists compensate for the negative effect of pollen-allergy and the adverse effect of inhaled corticosteroid treatment on bone fracture risk.]

[The increase of fracture risk in type 1 and type 2 diabetes mellitus]


[Studies in the last couple of years found more and more convincing evidence about the fact that impaired glucose metabolism leads to structural changes in the skeletal system leading toward osteoporosis. While patients with type 1 diabetes mellitus have decreased bone density, measurement showed increased bone mineral density in patients with type 2 diabetes mellitus. Despite these differences, risk of vertebral and nonvertebral fractures is increased in both groups of diabetic patients. Decreased pancreatic beta cell function is accompanied by several hormonal disturbances leading to decreased bone formation even in the early stage of diabetes. Peak bone mass of diabetic children is lower than found in nondiabetic children. Late complications of diabetes, vascular and neuronal impairments, impaired renal function, and secondary hormonal disturbances are added to this process. IGF-1 may have a crucial role in the pathogenesis of osteoporosis in diabetes. The structure of the molecule is similar to insulin. IGF-1 has effect on normal bone formation, inhibits the apoptosis and interferes with several other metabolic pathways. IGF-1 mediates the effect of growth hormone to the muscular and skeletal system. IGF-1 level decreases with age, and lower level of IGF-1 is found in diabetic patients. Long term complications of diabetes can also occur, which may enhance the process of bone resorption. Although the evidence is growing that fracture risk is higher in diabetic patiens, there are still scientists who question the association between the two disorders.]


[The influence of menopause-related obesity and related changes of body fat distribution on the severity of sleep apnea]


[INTRODUCTION - The menopause is associated with an enhanced risk of obesity. During the postmenopausal period changes in the distribution of body fat lead to a variety of disorders. Obesity is among the major risk factors for Obstructive Sleep Apnea Syndrome (OSAS). The prevalence of OSAS increases after the menopause. This study was intended to explore the relationship between the severity of sleep apnea and the quantity, as well as the distribution of body fat in postmenopausal women with this condition. PATIENTS AND METHODS - Sixty-two postmenopausal women (aged 58.6±7.4 years) were studied. Patients suffering from OSAS - established by cardiorespiratory polygraphy - were enrolled. None of the subjects received hormone replacement therapy during the trial. Total and regional quantity of body fat was determined by dualenergy X-ray absorptiometry (DXA). The distribution of body fat, the ratio of android-to-gynoid regional fat, as well as body mass index were automatically calculated by the software of the DXA machine. A specific region was defined to measure the fat content of the cervical region, extending from the mental protuberance to the clavicular plane. The reliability coefficient of the test method was calculated to check the accuracy of regional body fat measurement. The severity of obstructive sleep apnea was determined by cardiorespiratory polygraphy and expressed using the apnea/hypopnea index. RESULTS - Testing for independence in this population revealed the lack of independence between android-type obesity and severe OSAS. Specifically, 74% of patients with severe OSAS were obese (BMI>30 kg/m2). As with the android-type, the khi square test similarly refuted the independence between obesity and the severity of OSAS. Fat content of the cervical region was 25.2% in mild and moderate, and 30.2% in severe OSAS. Two-Sample t-test demonstrated the significant influence of cervical fat content on OSAS severity. CONCLUSION - Elevated BMI, android-type obesity, and higher relative fat content of the cervical region all aggravate obstructive sleep apnea in postmenopausal women.]

[Evaluation of bone mineral density in renal form of primary hyperparathyroidism]


[INTRODUCTION - The most frequent manifestations of primary hyperparathyroidism are renal stones or calcipenic osteopathy. The aim of authors was to examine how bones are affected (change of bone mineral density and frequency of fractures) in the renal form of primary hyperparathyroidism. METHODS - Mean age of the patients was 57 years (26 -81 years), (4 men, 33 women). Bone mineral density was measured in the lower third of the radius, femoral neck and lumbar 2-4 vertebrae by densitometers. Moreover, occurrence of fractures and biochemical parameters characteristic for hyperparathyroidism (serum parathyroid hormone levels, calcium, phosphorus, alkaline phosphatase, urinary calcium/ creatinine) were examined. RESULTS - Bone mineral density was normal in 6 cases, osteopenic in 10 patients and 21 patients had osteoporosis. Altogether five patients had fractures. Bone mineral density and biochemical parameters were not different in patients with or without fractures. CONCLUSIONS - Bone mineral density decreases in renal form of primary hyperparathyroidism even if there is no bone disease in the clinical picture. Therefore, bone mineral density measurement is advisable for every patient with hyperparathyroidism.]


[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.]

[Relationship between adipokinome and lipid parameters in Hungarian obese patients]

LŐRINCZ Hajnalka

[Since the prevalence of obesity has been dramatically increasing worldwide, a better understanding of obesity-related comorbidities leading to carbohydrate and lipid metabolism disorders has become essential. As an active endocrine organ, white adipose tissue secretes adipokines with diverse biological functions. We have found strong correlations between serum chemerin level and atherogenic lipoprotein sub-fractions in obese non-diabetic patients. To better characterize obese patients with and without manifest insulin resistance, we plan to determine serum levels of novel adipokines (omentin-1, vaspin, visfatin, lipocalin-2 and plasminogen activator inhibitor-1) and various oxidative stress markers including paraoxonase-1 activity, tumor necrosis factor-alfa and interleukin-6 levels, as well as low- and high-density lipoprotein subfractions in them and compare their data with lean individuals. We plan to determine correlations between the levels of novel adipokines and oxidative stress markers and lipoprotein subfractions. Furthermore, based upon our previous observations, we plan to study the potential alterations in the adipokine profile and the ratios of lipoprotein subfractions during a 5-year follow-up in obese patients. Our expected results may help to characterize the involvement of the adipokine profile in the regulation of lipoprotein metabolism. Early screening and treatment of lipid abnormalities may help to reduce the risk of cardiovascular events in obesity. ]

[Changing dietary guidelines in obesity. MOMOT recommendation]


[In the 70s and 80s due to the heart attack „epidemic” the low fat diet was encouraged based on the cholesterol theory, with moderate success. At the same time, the consumption of carbohydrates increased with the frequency of obesity rising from 1971 to 30% in the USA. Foods with high glicemic index and rich in carbohydrates result in a fast increase in glucose level, insuline actions also leading to glucose – fatty acid transformation and weight gain. Over the last decades several comparative trials have proven that with the low carb diet one can lose about 3- more than with the low fat diet in half a year. The excessive low carbohydrate Atkins diet over 1 year (), was superior even to ZONE (), LEARN (), ORNISH () diet, in another trial, over two years also the „low fat” diet. International Association for the Study of Obesity (IASO) recommends an increased protein intake (15 → 25%) along with carbohydrate with low glicemic index (GI). According to the summarized guidelines of the Hungarian Society of Obesitology and Excercise Therapy (MOMOT) low calorie (1200-1500 kcal / day), low-carb (<45%) – low-GI, high-protein (≥ 25%), low-fat (38→30%) diet is recommended, by witch a weight loss of 10 kg/half year can be expected. After half a year patient compliance deteriorates and they can hardly keep even the low-carb diet, whose significant advantage diminishes by this. We hope that patient compliance can be helped with two new appetite decreasing drugs, namely lorcaserin and a combination of phentermin and topiramat. Future dietary recommendations may be influenced by the new guideline issued in November 2013 by AHA/ACC, and the Obesity Society the final approval of which by NHLBI can be expected by June 2014.]

[The effect of obesity on cardiovascular diseases and the significance of the obesity paradox]


[Obesity represents a major health burden worldwide. Besides its growing prevalence, obesity contributes to the development of many cardiovascular diseases and thus increases the incidence of hypertension, diabetes, cardiomyopathy, heart failure, myocardial infarction, arrhythmias and stroke. Surprisingly, however, recent studies showed that in some cases obesity might improve survival and decrease the risk of mortality. This phenomenon has been named the obesity paradox. In this paper, we discuss the findings regarding this phenomenon and its possible biological explanations. We also draw the attention to the beneficial effects of individually tailored weight reduction therapy.]
