Hip Fracture Incidence Over Twenty Years in Poland: The HiPoL Study.

INTRODUCTION: In the previous report, we noted a significant increase in hip fracture incidence in the local study area. The aim of the study was the continuous observation of hip fracture incidence in the local community over the last 20 years and to estimate their projection for the next 30 years. METHODS: Medical records of the patients aged 50 years and older in the period 2002 - 2021 (local data - area of the district Tarnowskie Góry and the city of Piekary Slaskie) with diagnosis ICD-10: S72.0; S72.1; and S72.2 (only the fragility fractures) were taken into analysis. RESULTS: 2,723 fragility hip fractures in the local area were registered (72 % in women). The increase in the rate was constantly observed, even during the COVID - 19 pandemic. The incidence rate ratio for the local population increased to 1.41. The incidence rate in 2021 was for the total population 230.2 (men 151.3; women 294.2). For comparison in 2002, it was 129.0 (men 48.8; women 192.4). In 2050 the number of fractures according to our new estimation will increase. CONCLUSIONS: The number of fragility hip fractures in Polish men and women aged over 50 years in the local population increased. The epidemiological situation is still worsening. Therefore, especially due to the reduction of orthopedic beds and the aging population phenomenon the situation will be tragic to our patients.

Associations between the VDR Gene rs731236 (TaqI) Polymorphism and Bone Mineral Density in Postmenopausal Women from the RAC-OST-POL.

BACKGROUND: Postmenopausal osteoporosis is not only related to hormonal factors but is also associated with environmental and genetic factors. One of the latter is the polymorphism of vitamin D receptor (VDR). The aim of the reported study was to comprehensively analyze the VDR gene polymorphic variants rs731236 (TaqI), rs1544410 (BsmI) and rs7975232 (ApaI) in the Polish population of postmenopausal women. METHODS: The study group consisted of 611 women after menopause (their median age was 65.82 ± 6.29 years). Each of them underwent bone densitometry (DXA) of the non-dominant femoral neck and total hip with a biochemical analysis of vitamin D3 serum concentration and genotyping of the above-mentioned single nucleotide polymorphisms (SNPs); the obtained results were analyzed in the aspect of waist circumference (WC), body mass index (BMI) and past medical history. RESULTS: The genotype prevalence rates of all SNPs were compatible with Hardy-Weinberg equilibrium (p > 0.050). Out of the studied polymorphisms, only rs731236 genotype variants affected DXA, with AG heterozygotes showing the worst bone parameters. Neither patient age nor vitamin D3 concentration, BMI, WC or comorbidities was associated with rs731236 genotype. CONCLUSIONS: Out of the polymorphisms studied, only rs731236 genotypes differed among the DXA results, while the AG heterozygotes were characterized by the lowest median bone mineral density.

Height loss in postmenopausal women predicts multiple fractures in 10-year follow-up: results from the RAC-OST-POL study.

INTRODUCTION: In daily practice the diagnostic process for osteoporosis in elderly patients should also include physical assessment. The aim of the study was to verify the hypothesis that height loss (HL) predicts fracture incidence. MATERIAL AND METHODS: The study was performed in an epidemiological sample of postmenopausal women recruited in the RAC-OST-POL study. At baseline, data were collected in 978 postmenopausal women at a mean age of 66.48±7.6 years, and at 10-year follow-up 640 patients remained, with a mean age of 75.04 ± 6.95 years. Current height and HL were established in regard to maximal life height. Data on fracture incidence were gathered throughout the period of observation. RESULTS: During the follow-up period 190 osteoporotic fractures were noted. Ninety-one women had one fracture, and in 38 women, multiple fractures occurred. In the fractured and unfractured subgroups, HL was 5.45 ± 3.28 and 4.8 ± 3.56 cm, respectively, and differed significantly (p < 0.05). HL in subjects without fracture did not differ from those with one fracture (HL 4.8 ± 3.56 vs. 4.8 ± 2.66 cm, respectively). For patients with more than one fracture HL was 7.03 ± 4.06 cm and was significantly higher than in subjects with one or without any fracture (p < 0.01). Based on receiver operating characteristic (ROC) analysis, HL of 6 cm was identified as the cut-off point for high risk of multiple fractures. CONCLUSION: HL of at least 6 cm is the predictor of multiple fractures in a prospective observation of a representative epidemiological female sample. Therefore, the measurement of HL should always be included in patients' assessments.

Limited utility of salivary mineral content in prediction of fragility fractures among postmenopausal women.

BACKGROUND: Osteoporosis is a metabolic disease characterized by increased bone fragility. As it is characterized as a general skeletal disease, changes can also be seen in the stomatognathic system (edentulism, wrong fitting of dentures, etc.). The question is whether early changes in the salivary mineral content and acid-base balance may reflect skeletal status and risk of bone fracture. OBJECTIVES: The objective of the study was to evaluate whether minerals in the saliva were associated with skeletal fractures in a population of postmenopausal women. MATERIAL AND METHODS: In this observational study, dental examinations along with the collection of saliva were conducted in 117 randomly recruited women (mean age 64.6 ±5.9 years). The study group included 23 study participants with fractures, of which 10 had a history of osteoporotic fractures. Saliva samples for mineral content including copper (Cu), zinc (Zn), calcium (Ca), and phosphorus (P), as well as salivary pH were collected and analyzed to determine associations between salivary mineral content and fracture risk. RESULTS: As a result, the median pH value was 6.8, and the median levels for Cu (0.35 µmol/L), Zn (0.61 µmol/L), Ca (0.7 mmol/L), and P (6.64 mmol/L) were observed. No differences were noted in salivary mineral content and acid-basic balance between the fractured and non-fractured participants. CONCLUSIONS: The results of our study suggest that salivary mineral content has limited usability in predicting skeletal fragility in postmenopausal women when used alone.

OSTEOPOROSIS FROM YESTERDAY TO TODAY ­ A NARRATIVE REVIEW

Despite different lifestyles, humankind has suffered from osteoporosis for thousands of years. A literature review concerning the history of osteoporosis in the following databases: Index Medicus, Medline, PubMed, and PMC Citations was done. In the final analysis, 18 review articles and 31 original papers were included. The works were published during the period 1705-2020. Although there is evidence of the existence of osteoporosis for many centuries, it was first described as a disease at the beginning of the 18th century. It was first perceived as an unavoidable course of aging with no possibility to cure. This approach changed only in the 20th century thanks to sudden diagnostic and therapeutic progress. This paper presents the milestones and most important researchers in osteoporosis history. Rapid progress in diagnostic and therapeutic possibilities sheds new light on osteoporosis' nature. A comprehensive outlook on its history may help find answers for the still unsolved problems of this disease.

Height Loss Is an Independent Predictor of Fracture Incidence in Postmenopausal Women: The Results from the Gliwice Osteoporosis Study (GO Study).

BACKGROUND: The aim of a longitudinal, retrospective study was to establish variables predicting fracture incidence over a decade. METHODS: The study sample comprises a group of 457 postmenopausal women aged over 55 years, recruited from the database of an outpatient osteoporotic clinic. Several variables with potential influence on bone status, including the measurement of body height and hip bone densitometry, were collected. BMD at the femoral neck (FN BMD) was established using a Prodigy device (Lunar, GE, USA). Current body height was compared with the maximal historical body height in early adulthood, as reported by the patient. RESULTS: Three hundred and ninety-four women did not have fractures during the follow up, and 63 subjects presented fractures. Subjects with fracture had lower FN BMD with a T-score of -1.86 ± 1.04 compared to -1.44 ± 0.89 in those without fractures (p < 0.001). Mean height loss (HL) was 3.47 ± 2.11 cm in fractured subjects and 2.50 ± 2.47 cm in unfractured ones, and differed significantly, p < 0.01. Fracture incidence was significantly related to age, rheumatoid arthritis, falls, and previous fractures. In the multivariable analysis using logistic regression, FN BMD, baseline fracture, and HL were identified as the significant predictors of fractures of follow up. CONCLUSIONS: Osteoporotic fractures in postmenopausal women were predicted by FN BMD, prior fracture(s), and HL easily established during physical examination.

Functional status as a predictor of the incidence of falls in 10-year follow-up: results from the RAC-OST-POL study.

INTRODUCTION: The aim of this prospective study was to establish the influence of baseline functional status on the incidence of falls. MATERIAL AND METHODS: The study was performed in an epidemiological sample of postmenopausal women from the RAC-OST-POL study. At baseline there were 978 postmenopausal women with a mean age of 65.9 ± 7.6 years, and at the end of 10-year follow-up 640 patients with a mean age of 65.04 ± 6.95 years remained in observation. Functional status was established at baseline using a stand up and go test (SAG) and the Lawton Instrumental Activities of Daily Living (IADL) scale. Afterwards, data on fall incidence were updated annually using phone interviews. RESULTS: In a 10-year period of observation, in 384 (60%) women at least one fall occurred. At baseline, 90% of subjects achieved maximal value in the IADL scale (24 points). Although the difference between mean IADL score in those who fell and did not fall was noticeable (23.50 ± 1.68 vs. 23.65 ± 1.47, respectively), the category of any IADL score below 24 points was significantly more frequent in women with falls (71.9% vs. 28.1%; chi-square 4.2, p < 0.05). The SAG score in the subgroup with falls was (10.75 ± 3.39) and did not differ in comparison to subgroup without falls (10.27 ± 2.72). CONCLUSION: The baseline result of the IADL scale but not that of the SAG test are related to the incidence of falls in a 10-year prospective observation. Adequate correction of functional status may benefit patients and reduce the fall rate.

Assessment of Osteoporosis and Vitamin D3 Deficiency in Patients with Idiopathic Benign Paroxysmal Positional Vertigo (BPPV).

Background and objectives: Osteoporosis and vitamin D3 deficiency may be risk factors of benign paroxysmal positional vertigo (BPPV). The aim of this study was to assess the prevalence of osteoporosis and 25(OH) vitamin D3 deficiency in a group of patients with idiopathic benign paroxysmal positional vertigo. Materials and Methods: Thirty-five patients (twenty-eight women and seven men) with posterior semicircular canal BPPV were enrolled in the study. The subjects underwent hearing assessment (tonal audiometry and impedance audiometry) and the Dix-Hallpike maneuver. Serum 25(OH) vitamin D3 levels were determined and lumbar spine bone densitometry was performed. The relationships between sex, age, height, Body Mass Index (BMI), vitamin D3 levels and bone densitometry results were assessed. Results: The diagnosis of osteoporosis was confirmed in 1 patient (3%), 3 subjects were osteopenic (8.6%), and normal bone densitometry was found in 31 (88.6%) patients. Conclusions: We found no statistically significant relationships between age, BMI or vitamin D3 levels and bone densitometry results in patients with idiopathic BPPV.

POL-RISK: an algorithm for 10-year fracture risk prediction in postmenopausal women from the RAC-OST-POL study.

INTRODUCTION: Fragility fractures are the major consequence of osteoporosis. Thus, fracture risk assessment is an essential part of the diagnostic process in osteoporosis. OBJECTIVES: The aim of the study was to develop an algorithm for fracture risk prediction. PATIENTS AND METHODS: Bone status was evaluated in a population­basedcohort of postmenopausal women at a mean (SD) age of 66.4 (7.8) years. Subsequently, all participants were contacted by phone once a year (for 10 consecutive years) to update their history of fractures. At the end of the 10­year follow­up, the number of the study participants was 640, of whom 129 had a history of 190 osteoporotic fractures recorded during the study period. Statistical analysis included multistep data preprocessing, feature selection, identification of fracture risk factors, and design of the final model. Logistic regression models were fitted and used for the evaluation of variables from determined feature sets, including global fit measures, as well as individual parameters, such as the Wald statistic and P value, odds ratio, and 95% CI. RESULTS: The 10­year risk for any fracture depended on the age of the patient, the number of recorded fractures after the age of 40 years, femoral neck bone mass, and the occurrence of falls during the previous year. The achieved equation was incorporated into an algorithm, available at the www.fracture­risk.pl webpage. CONCLUSION: A fracture prediction algorithm was developed in a longitudinal study to enable calculation of the 10­year fracture risk. Identification of patients at a high risk of fracture should be followed by implementation of appropriate treatment strategy to reduce the number of future fractures.

Impaired Functional Status Increases Fracture Incidence in 10-year Follow-Up: The Results from RAC-OST-POL Study.

INTRODUCTION: The aim of study was to establish the influence of baseline functional status on fracture incidence. METHODOLOGY: In a prospective 10-years observation in epidemiological sample of postmenopausal women from RAC-OST-POL Study a thesis that affected functional status enhance fracture incidence was verified. At baseline, data were collected in 978 women at mean age 66.48±7.6 years and after 10 years of follow-up 640 subjects at mean age 75.04±6.95 years remained in the study. Functional status at baseline was established using Stand up and Go test (SAG) and Activity of Daily Living (IADL). Afterwards, annually data on fracture incidence were collected by phone interviews. RESULTS: In the period of observation 190 low-energy fractures in 129 women were noted. The whole group was divided into subgroups: without fracture (n=511), with one fracture (n=91) and those ones who had more than one fracture (n=38). In fractured and unfractured subgroup mean SAG results were 11.36±4.28 and 10.36±2.76, respectively and differed significantly (p<0.01). With increasing number of fractures the SAG time was longer - it was 11.15±4.49 in one fracture subgroup and 11.87±3.73 in multiple fractures subgroup, with both values significantly higher than in no fracture subjects. The mean value of IADL was 23.56±1.60. In 576 (90%) women IADL reached maximal value of 24 points. In the rest of them (n=64) IADL score was between 11 and 23 points. Mean value of IADL in fractured and unfractured subgroup were 23.27±1.97 and 23.64±1.47, respectively and differed significantly (p<0.01). CONCLUSION: The measures of functional status predict fractures in a prospective observation of representative epidemiological female sample.

Fracture risk and fracture prevalence in women from outpatient osteoporosis clinic and subjects from population-based sample: A comparison between GO Study and RAC-OST-POL cohorts.

BACKGROUND: The method of recruiting the study subjects is an important element of the study design. It can have a strong influence on the results. Different recruitment schedules can give a different picture of the studied phenomenon. OBJECTIVES: The aim of the study was to compare bone health in a group of female patients treated for osteoporosis with a population-based sample. MATERIAL AND METHODS: A cohort of women from GO Study from 1 outpatient osteoporotic clinic (n = 1442, mean age 65.8 ±6.7 years) and population-based female sample of RAC-OST-POL Study (n = 963, mean age 65.8 ±7.5 years) were studied. Mean age did not differ between groups. Mean weight, height and body mass index (BMI) in subjects from GO Study and RAC-OST-POL Study were 69.5 ±13.1 kg, 157.8 ±6.1 cm and 27.9 ±5.1 kg/m2, and 74.2 ±13.7 kg, 156.0 ±6.0 cm and 30.5 ±5.4 kg/m2, respectively, and differed significantly (p < 0.0001 for each variable). Data on clinical risk factors for osteoporosis and fractures were collected. Bone densitometry at hip was performed using a Prodigy or Lunar DPX device (GE Healthcare, Waukesha, USA). Fracture risk was established using FRAX, Garvan and POL-RISK. RESULTS: Mean values of T-score for femoral neck in subjects from GO Study and RAC-OST-POL Study were -1.67 ±0.91 and -1.27 ±0.91 and differed significantly (p < 0.0001). In GO Study and RAC-OST-POL Study, there were 518 (35.9%) and 280 (29.1%) subjects with fractures, respectively. The fracture frequency was significantly higher in the GO Study group (p < 0.001). Among clinical risk factors, only rheumatoid arthritis (p < 0.0001) secondary osteoporosis (p < 0.0001) and falls (p < 0.0001) were more frequent in RAC-OST-POL Study. Fracture risk established using FRAX, Garvan and POL-RISK calculators was significantly greater in patients enrolled in the GO Study than in subjects from the RAC-OST-POL population-based sample (p < 0.0001 for each variable). CONCLUSIONS: Differences noted between female patients treated for osteoporosis and population-based sample, especially in regard to fracture risk, reveal a strong influence of recruitment criteria on study results in the field of bone health and osteoporosis.

The Impact of Environmental and Genetic Factors on Bone Quality in Monozygotic and Dizygotic Twins.

The purpose of the research was to assess the genetic and environmental influences on bone properties. One hundred thirty-two pairs of twins (99/33 monozygotic/dizygotic) underwent anthropometric measurements and phalangeal quantitative ultrasound (DBM Sonic 1200, Igea, Italy) measuring the amplitude speed of sound (AD-SoS, m/s). The mean age was 16.78 ± 12.35 years for monozygotic twins and 14.30 ± 8 years for dizygotic. Interpair and intrapair correlations between twins were calculated. In the groups of monozygotic and dizygotic twins, Ad-SoS correlated significantly with age (r = 0.56−0.73, p < 0.05), weight (r = 0.73−0.78, p < 0.05), and height (r = 0.80−0.81, p < 0.05). The strongest intrapair correlation (r = 0.99−0.998) was noted in monozygotic females for Ad-SoS, weight, and height. There was a statistically significant correlation between the intrapair difference of Ad-SoS and age but only in the groups of monozygotic and dizygotic females (r = 0.281, r2 = 0.079, and p = 0.028; r = 0.544, r2 = 0.296, and p = 0.01, respectively). After age adjustment, it was estimated that 28.62% of Ad-SoS in women and 13.2% of Ad-SoS in men was explained by genetic influence, leading to the conclusion that Ad-SoS changed with age, weight, and height. The strongest correlation between pairs of twins was observed in monozygotic twins. The differences in bone values between female twins arose with age, which indicated the role of environmental factors.

Higher education and better knowledge of osteoporosis improve bone health in Polish postmenopausal women.

INTRODUCTION: The aim of the study was to establish the influence of knowledge of osteoporosis and educational level on bone health. MATERIAL AND METHODS: The study group consisted of 351 women, aged 50-88 years (mean 66.3 ± 8.6). None of them had had any previous personal experience with osteoporosis diagnosis and treatment. They filled in a questionnaire consisting of 10 questions assessing their knowledge about osteoporosis. All of them underwent femoral neck densitometry (GE Lunar, USA). RESULTS: The mean score in the knowledge questionnaire was 7.4 ± 1.6 points (range 2-10). The lowest percentage of correct answers was observed in the sentences regarding the possibility of successful cure of osteoporosis and the role of physical activity in osteoporosis treatment. The mean score in the osteoporosis questionnaire correlated negatively with the age of the participants (r = -0.2, p < 0.05) and was better among patients with higher educational degree (8.2 vs. 6.4 points, p < 0.001). Both the educational degree and the level of knowledge of osteoporosis correlated with bone mineral density (BMD) and T-score. CONCLUSIONS: Elderly and less educated women showed lower levels of knowledge about osteoporosis and its consequences. The study suggests that bone health in postmenopausal women may be indirectly improved by education concerning osteoporosis and its prevention.

Changes in osteoporosis therapy in postmenopausal women from the RAC­OST­POL study: a 10­year follow­up.

INTRODUCTION: Therapeutic regimens for osteoporosis are the key elements in the management of osteoporotic patients. OBJECTIVE: The aim of the study was to present data on changes in osteoporosis therapy in women during a 10­year follow­up. PATIENTS AND METHODS: We analyzed a population­based sample recruited in the RAC­OST­POL study. At baseline, the cohort included 978 women, of whom 541 remained in the follow­up. Mean (SD) age of the patients was 74.7 (6.6) years. RESULTS: The number of untreated women and those on alendronate decreased, while the number of patients receiving other forms of the antiresorptive therapy or calcium / vitamin D supplementation increased during the study. The percentage of untreated women in the rural areas and the urban areas was, respectively, 85% and 74.1% at baseline, and 74.3% and 63.3% at the end of the follow­up. The percentage of untreated women decreased significantly, both in rural and urban cohorts. It was accompanied by a significant increase in calcium / vitamin D supplementation in both subgroups. Regarding the antiresorptive therapy, there was a significant increase in the frequency of its use only in the rural cohort. The use of therapeutic strategies was determined by the level of education. The frequency of calcium and / or vitamin D supplementation increased significantly in all education-related categories during the follow­up. CONCLUSION: Changes in the therapy of postmenopausal women with osteoporosis, observed in a 10­year follow­up of the RAC­OST­POL study, indicated that the level of care did not improve in this group of patients.

One year of the COVID-19 pandemic in Poland-the incidence of osteoporotic forearm, arm, and hip fractures.

The study attempts to analyse whether the COVID-19 pandemic affected the incidence of forearm, arm, and hip fractures during a 1-year observation period. Additionally, changes in the overall treatment costs of those fractures were estimated. During the COVID-19 pandemic, the incidence of forearm, arm, and hip fractures remained statistically unchanged, neither were any significant changes observed in the expenditure, incurred for the treatment of the fracture cases. PURPOSE: The purpose of the study was to find out and evaluate if the consequences of COVID-19 pandemic (including lockdown and the fear of infection) influenced the incidence of osteoporotic forearm, arm, and hip fractures and to estimate the changes in the costs of their management during one-year observation period. METHODS: The incidence of forearm, arm, and hip fractures was collected for the population, aged ≥ 50, residing at the district of Tarnowskie Góry and the Town of Piekary Slaskie, Poland, during 1 year of COVID-19 pandemic (from March 16th 2020 to March 15th 2021). The obtained results were compared with the number of corresponding limb fractures, recorded before the pandemic during five consecutive yearly periods, each starting from 16th March and ending on the 15th March of a subsequent year, the entire period covering the years 2015-2020. The rates of the analysed fractures were calculated per 100,000 inhabitants together with their economic impact. RESULTS: The mean numbers and the incidence rates of upper extremity fractures were slightly lower during the COVID-19 pandemic than in the previous 5 years, whereas hip fracture figures remained almost stable. The observed changes were not statistically significant. That annual observation revealed a slight decrease in expenditure volumes, when compared to the analysed period before the pandemic (-0.33%). CONCLUSION: The decreased incidence rate of forearm, arm, and hip fractures, observed during the first months of the COVID-19 pandemic, was not statistically significant in the 1-year observation. After several weeks/months under the shock, caused by government limitations and the fear of infection, the number of patients remained unchanged during the one-year observation.

[The relationship between chemerin, bone metabolism, the RANKL/RANK/OPG system, and bone mineral density in girls with anorexia nervosa].

INTRODUCTION: Based on recent studies in humans, chemerin has been classified as an adipokine that might be associated with osteoporosis and BMD. Bone loss is common in adolescents with anorexia nervosa (AN). Moreover, dysfunction in the production of chemerin has also been shown. Therefore, we carried out a comparative analysis between chemerin, bone metabolism, the RANKL/RANK/OPG system, and BMD in girls with AN. MATERIAL AND METHODS: Plasma chemerin, OC, CTx, OPG, and sRANKL were determined by ELISA in 75 girls with AN aged 12.6-17.8 years. BMD was assessed by DXA and expressed as Z-score according to the lumbar spine (s) and total body (TB) sites. According to the s-BMD- and TB-BMD Z-score, girls with AN were divided into two subgroups with parallel analyses used: normal (Z-score > -2.0) and low (Z-score ≤ -2.0) s-BMD, and normal (Z-score > -2.0) and low (Z-score ≤ -2.0) TB-BMD. RESULTS: Mean OC and the OPG/sRANKL ratio were markedly lower in the low s-BMD subgroup compared to the normal s-BMD subgroup. The s-Z-score values (both low and normal) correlated significantly and positively with the OPG/sRANKL ratio. Only in the low s-BMD subgroup did chemerin correlate significantly and positively with all nutritional indices and the OPG/sRANKL ratio. In the low TB-BMD subgroup the mean OC and the OPG/sRANKL ratio were lower than in the normal TB-BMD subgroup. The TB-Z-score values (both normal and low) correlated significantly and positively with all nutritional indices and the OPG/sRANKL ratio. The low TB-Z-score values correlated significantly and positively also with chemerin. In the low TB-BMD subgroup chemerin correlated significantly and positively with weight and BMI (expressed as absolute values), Cole index, the duration of the disease, and OPG/sRANKL ratio while its correlation with age was negative. CONCLUSIONS: Undernutrition and associated deficit of adipose tissue may result in inadequate chemerin production and skeletal disorders in girls with AN. Chemerin acts as a coordinator of the dynamic balance between bone metabolism and the OPG/RANK/RANKL system and, in turn, may contribute to the loss of bone mass in girls with AN. The cortical bone site seems to be more severely responsive to chemerin actions than the trabecular bone site.

Glucocorticoids Increase Fracture Risk and Fracture Prevalence Independently from Bone Mineral Density and Clinical Risk Factors: Results from the Gliwice Osteoporosis (GO) Study.

The aim of the study was to establish the influence of glucocorticoids (GC) on fracture risk, probability, and prevalence. A set of 1548 postmenopausal women were divided into study group - treated with GC (n=114, age 66.48±7.6 years) and controls (n=1434, age 66.46±6.83 years). Data on clinical risk factors for osteoporosis and fractures were collected. Hip bone densitometry was performed using a device Prodigy (GE, USA). Fracture probability was established by FRAX, and fracture risk by Garvan algorithm and POL-RISK. Fracture risk and fracture probability were significantly greater for GC-treated women in comparison to controls. In the study group, there were 24, 3, 24, and 6 fractures noted at spine, hip, forearm, and arm, respectively. The respective numbers of fractures reported in controls at those skeletal sites were: 186, 23, 240, and 25. The use of GCs increased significantly prevalence of all major, spine and arm fractures. Also the number of all fractures was affected by GC use. Following factors significantly increased fracture probability: age (OR 1.04 per each year; 95% CI: 1.03-1.06), GC use (OR 1.54; 95% CI: 1.03-2.31), falls (OR 2.09; 95% CI: 1.60-2.73), and FN T-score (OR 0.62 per each unit; 95% CI: 0.54-0.71). In conclusion, in patients treated with GCs the fracture risk, probability, and prevalence were increased. This effect was evident regardless of whether GC therapy is included in the algorithm as a risk factor (FRAX, POL-RISK) or not taken into consideration (Garvan nomogram).
