Risk Factors For Osteoporosis Research Articles

The impact of chronic obstructive pulmonary disease on bone strength.

Chronic obstructive pulmonary disease (COPD) is a lifestyle-related disease that develops in middle-aged and older adults, often due to smoking habits, and has been noted to cause bone fragility. COPD is a risk factor for osteoporosis and fragility fracture, and a high prevalence of osteoporosis and incidence of vertebral fractures have been shown in patients with COPD. Findings of lung tissue analysis in patients with COPD are primarily emphysema with a loss of alveolar septal walls, and the severity of pulmonary emphysema is negatively correlated with thoracic spine bone mineral density (BMD). On the other hand, epidemiological studies on COPD and fracture risk have reported a BMD-independent increase in fracture risk; however, verification in animal models and human bone biopsy samples has been slow, and the essential pathogenesis has not been elucidated. The detailed pathological/molecular mechanisms of musculoskeletal complications in patients with COPD are unknown, and basic research is needed to elucidate the mechanisms. This paper discusses the impacts of COPD on bone strength, focusing on findings in animal models in terms of bone microstructure, bone metabolic dynamics, and material properties.

Pre-existing osteoporosis and serum vitamin D levels in patients with distal radius fractures: are we missing something?

IntroductionGiven the significant therapeutic gap for osteoporosis, this study aims to investigate the most common osteoporosis-related fracture. The analysis will also consider patients’ serum vitamin D levels and the indications for basic osteoporosis diagnostic tests and osteoporosis therapy prior to fracture.Materials and methodsThis prospective clinical trial included patients with distal radius fractures who underwent surgery at our hospital between 1 April 2021 and 7 April 2022. Blood samples were taken from all participants and existing risk factors for osteoporosis were recorded. In addition, the indication for a guideline-based osteoporosis diagnosis was assessed and the risk of another future fracture with FRAX® was calculated. This information was used to decide whether there was an indication for specific osteoporosis therapy.ResultsA diagnosis gap of 53% and a treatment gap of 84% were identified among the 102 patients investigated. The patients’ ages ranged from 46 to 91 years, with an average vitamin D level of 57 nmol/l, which was below the recommended level of 75 nmol/l. It was noted on a monthly basis that the vitamin D level (without substitution) never exceeded the recommended value of 75 nmol/l in any month. Three-quarters of patients had indications for a baseline osteoporosis diagnosis, yet less than 50% received one. According to FRAX® data, 57% of patients had indications for specific osteoporosis treatment before experiencing the fracture.ConclusionEven without a previous distal radius fracture, many patients are in need of osteoporosis diagnosis or treatment. Our research suggests that patients with distal radius fractures should have their vitamin D levels checked via a blood test and be evaluated for osteoporosis. As endogenous vitamin D levels are often inadequate, year-round vitamin D supplementation should be considered for the prevention of osteomalacia and as a basis for the treatment of osteoporosis.German clinical trial register IDDRKS00028085.

The evaluation of the effect of long-term antihypertensive drug usage on bone density with dental volumetric tomography.

HT is a systemic disease that presents with persistent high blood pressure, which has become an important health problem due to its cause of serious complications and high prevalence in the community. Aim: This study aims to examine the bone mineral density (BMD) of male patients using different groups of antihypertensive drugs for long terms with dental volumetric tomography. The study was carried out using the data of patients who applied to the Dicle University Faculty of Dentistry and underwent the Dental Volumetric Tomography (DVT) scan for any reason. The patients included in the study were divided into 4 groups according to their antihypertensive use; Group 1: 60 patients who never used hypertensive medication before, Group 2: 60 patients who received Calcium Channel Blocker treatment for over 5 years, Group 3: 60 patients who received Beta Blocker treatment for over 5 years, Group 4: 60 patients who received ACE inhibitor treatment for over 5 years. Radiomorphometric measurements were made on the DVT data and the DVT-Mandibular Index Inferior, DVT-Cortical Index, Hounsfield Unit-Cortical and Hounsfield Unit-Spongios values were calculated. The Kruskal-Wallis test, the Mann Whitney test with Bonferroni correction, the One-Way ANOVA and Post-Hoc Tukey test were used in the study. A significant increase in DVT-CI and a significant decrease in HU-CORTIKAL, HU-SPONGIOS and DVT-MII values were observed in the patients using Calcium Channel Blocker medication. These findings pointed to osteoporosis. In addition, no statistically significant difference in the use of antihypertensive drugs in the Beta Blocker and ACE Inhibitor groups compared to the Control Group were found. The long term use of Calcium Channel Blocker group antihypertensive drugs should be considered as a risk factor for osteoporosis in men. Key words:Antihypertensive drug, Osteoporosis, Radiomorphometric index, Mandible, Dental volumetric tomography, Bone mineral density.

Comparison of bone mineral density between female amateur triathletes and nonathletes: A cross-sectional study.

Physical inactivity is considered an important risk factor for osteoporosis, however, some athletes performing extremely high training volumes can also develop bone mass loss. Moreover, the effect of total body mass or body surface area on bone mineral density remains controversial. Therefore, the aim of this study was to compare the absolute bone mineral density and bone mineral density adjusted to body surface area between amateur triathletes and nonactive women. Forty-two healthy women (23 amateur triathletes and 19 nonactive individuals) were evaluated for body composition using a dual-energy X-ray absorptiometry system. Compared to nonactive women, amateur triathletes exhibited lower body mass index (p < 0.001), lower bone mineral density (p < 0.001), and body surface area (p < 0.001). However, bone mineral density adjusted by body surface area in the triathletes was higher than in the nonactive women (p = 0.03). These findings showed that amateur triathles presented lower absolute bone mineral density, but higher bone mineral density adjusted to body surface area. Future studies are recommended to identify if the higher bone mineral density adjusted to body surface area are associated with a lower bone fragility.

Probability of the 10-year Risk of Hip and Major Osteoporotic Fracture in Non-radiographic Axial Spondyloarthritis.

Fracture risk in non-radiographic spondyloarthritis is underestimated. A reliable tool such as the Fracture Risk Assessment tool (FRAX) may assess this risk probability. This study aimed to assess the fracture risk by the FRAX score in patients with nr-axSpA and to determine factors associated with high fracture risk. We conducted a retrospective study of nr-axSpA patients meeting the Assessment of SpondyloArthritis International Society (ASAS) classification criteria for spondyloarthritis. All patients had Bone Mineral Density (BMD) by dual-energy X-ray absorptiometry (DEXA). The 10- year probability of major osteoporotic fracture (MOF) and hip fracture (HF) was calculated using the Fracture Risk Assessment Tool (FRAX). Among 40 patients with nr-axSpA, 27 were women (67.5%). Their mean age was 43.7 ± 12.1 years. The mean disease duration was 3.15 ± 2.7 years. Eighteen patients (45%) had osteopenia, and 12 patients (30%) had osteoporosis. The median HF FRAX was 0% [0-1.2]. The median MOF FRAX was 0.5% [0.3-1.8]. MOF FRAX was positively correlated with age (p = 0.002), disease onset age (p = 0.006), disease duration (p = 0.024), and the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) (p < 0.0001), and negatively correlated with daily calcium intake (p < 0.0001). HF FRAX was positively correlated with mSASSS (p < 0.0001) and negatively correlated with daily calcium intake (p = 0.005). Our study confirmed the frequency of bone loss during nr-axSpA and showed that osteoporotic risk fracture was related not only to traditional risk factors for osteoporosis but also to disease-related factors.

Comparison of the prevalence of osteoporosis in people with spinal cord injury according to bone mineral density reference values for the diagnosis of osteoporosis: a retrospective, cross-sectional study

BackgroundSpinal cord injury (SCI) is a complex cause of rapid low bone mass that easily predisposes the affected individuals to osteoporosis-induced fractures. Several studies have investigated osteoporosis pathophysiology in SCI; however, those associated with its diagnosis in SCI are limited. Additionally, errors in osteoporosis diagnosis and its prevalence vary based on the bone mineral density (BMD) reference values (BMDRV), and no studies have reported BMDRV application for osteoporosis diagnosis in individuals with SCI. Therefore, this study aimed to compare the prevalence of osteoporosis among Korean adults aged ≥ 50 years with SCI according to BMDRV for diagnosing osteoporosis.MethodsOverall, 855 patients with SCI who underwent BMD tests of the lumbar spine, femoral neck, and total hip at the National Rehabilitation Center (NRC) in Korea between 2010 and 2020 were included in this retrospective cross-sectional study. Osteoporosis was diagnosed in patients with SCI by comparing the differences in prevalence, diagnostic consistency, and risk factors according to the region-based BMDRV of the dual-energy x-ray absorptiometry (DXA) manufacturer and international BMDRV based on the Third National Health and Nutrition Examination Survey (NHANES III) data of females aged 20–29 years.ResultsThe prevalence of osteoporosis according to the T-score provided by a single reference population of the NHANES III (TNHA) (PONHA) (males: 26.69%; females: 69.35%) was significantly higher in females and males than that according to the T-scores provided by the DXA manufacturer (TDXA) (PODXA) (males: 15.32%; females: 43.15%). The lumbar spine and femoral neck were major osteoporosis diagnosis sites for the PODXA and PONHA, respectively. Risk factors for osteoporosis differed based on the probability of osteoporosis (also known as the OZ ratio) according to the BMD criteria; however, the risk factors were similar according to old age, female sex, low body mass index (BMI), and long SCI period. No significant relationship was noted between the different SCI-related clinical factors (p > 0.05).ConclusionsThe osteoporosis diagnostic site and prevalence in SCI differed according to the regional-based TDXA and international standards of the TNHA. Therefore, further studies on BMDRV are warranted to establish accurate diagnostic criteria for osteoporosis prevention in patients with SCI.

Potentially inappropriate prescriptions and potential prescription omissions in older people living with HIV.

This study aimed to determine the prevalence of potentially inappropriate prescriptions (PIPs) and potential prescription omissions (PPOs) in a Spanish cohort of people living with HIV (PLWH) aged ≥65 years and to identify risk factors for the presence of PIPs and PPOs. This retrospective cross-sectional study was conducted across 10 public hospitals in the Autonomous Community of Madrid, Spain. Clinical and demographic data were cross-checked against hospital and community pharmacy dispensation registries. PIPs and PPOs were assessed using the American Geriatrics Society (AGS)/Beers and Screening Tool of Older Persons' Prescriptions (STOPP)/Screening Tool to Alert Doctors to Right Treatment (START) criteria. Risk factors for PIPs and PPOs and agreement between AGS/Beers and STOPP/START criteria were statistically analysed. This study included 313 PLWH (median age 72 years), of whom 80.5% were men. PIP prevalence rates were 29.4% and 44.4% based on the AGS/Beers and STOPP criteria, respectively. The concordance between AGS/Beers and STOPP criteria was moderate. Benzodiazepines and proton pump inhibitors were the chronic comedications most commonly involved in PIPs. PPOs were observed in 61.4% of the patients. The leading omissions were insufficient influenza and pneumococcal vaccine coverage and inadequate bone health-related treatments. The number of chronic comedications, female sex, neuropsychiatric disorders, and cancer diagnosis were risk factors for PIPs, whereas osteopenia and osteoporosis were risk factors for PPOs. A high prevalence of PIPs and PPOs was observed in our cohort of older PLWH. These findings emphasize the importance of comprehensive medication reviews in this population to reduce inappropriate medication use and address their specific and underserved therapeutic needs.

Smoking, alcohol consumption, drug abuse, and osteoporosis among older adults: a cross-sectional study on PERSIAN cohort study in Fasa

BackgroundWith increasing life expectancy and a growing population of older adults, the prevalence of osteoporosis has risen, resulting in a higher incidence of bone fractures, which necessitate extended treatment and specialized medical care. This study investigates the relationship between smoking, alcohol consumption, drug abuse, and osteoporosis among older adults in southern Iran, utilizing cohort data.MethodsThis cross–sectional study is derived from the Fasa Adult Cohort Study (FACS), which included 10,133 individuals. From this cohort, we selected 1,631 older adults using census sampling methods. Our study aimed to explore the correlation between smoking, alcohol consumption, and drug abuse among older adults and the incidence of osteoporosis. We collected demographic information, nutritional indexes, medical history, glucocorticoid usage, and self-reported data on smoking, alcohol consumption, drug abuse, and osteoporosis through questionnaires. To investigate the relationship between smoking, alcohol, and drug use with osteoporosis while accounting for confounding factors, we employed logistic regression analysis.ResultsThe average age of the study participants was 64.09 ± 3.8 years, with a majority (898 (55.1%)) being female. Osteoporosis prevalence among the subjects was 25.20%. The results did not reveal a significant correlation between smoking, alcohol consumption, drug abuse, and osteoporosis (p > 0.05). Regression analysis identified gender, recent history of fractures within the past five years, history of using glucocorticoids, and physical activity as significant predictive risk factors for osteoporosis within the study population (p < 0.05).ConclusionThe study underscores the significance of addressing osteoporosis risk factors in older adults. Healthcare policymakers and administrators can use these findings to identify and mitigate influential factors contributing to osteoporosis in this demographic.

Treatment of patients with chronic periodontitis on the background of vitamin D deficiency

Lack of response to the treatment of periodontal disease depends on systemic disturbances, one of which is vitamin D deficiency. Vitamin D deficiency is an absolute risk factor for osteopenia and osteoporosis for adult and aged patients. The analysis of clinical and laboratory studies results revealed a positive dynamic of the treatment given. The obtained data prove the necessity of vitamin D status correction in the combined treatment of the periodontal profile patients.

Association of serum osteocalcin with bone microarchitecture and muscle mass in Beijing community-dwelling postmenopausal women.

Osteoporosis is a systemic skeletal disease with increasing bone fragility and prone to fracture. Osteocalcin (OC), as the most abundant non collagen in bone matrix, has been extensively used in clinic as a biochemical marker of osteogenesis. Two forms of OC were stated on circulation, including carboxylated osteocalcin (cOC) and undercarboxylated osteocalcin (ucOC). OC was not only involved in bone mineralization, but also in the regulation of muscle function. This study explored the relationship between serum OC, cOC, ucOC levels and bone mineral density (BMD), bone microarchitecture, muscle mass and physical activity in Chinese postmenopausal women. 216 community-dwelling postmenopausal women were randomized enrolled. All subjects completed biochemical measurements, including serum β-isomer of C-terminal telopeptides of type I collagen (β-CTX), N-terminal propeptide of type 1 procollagen (P1NP), alkaline phosphatase (ALP), OC, cOC and ucOC. They completed X-ray absorptiometry (DXA) scan to measure BMD, appendicular lean mass (ALM) and trabecular bone score (TBS). They completed high resolution peripheral quantitative CT (HR-pQCT) to assess peripheral bone microarchitectures. Serum OC, cOC and ucOC were elevated in osteoporosis postmenopausal women. In bone geometry, serum ucOC was positively related with total bone area (Tt.Ar) and trabecular area(Tb.Ar). In bone volumetric density, serum OC and ucOC were negatively associated with total volume bone mineral density (Tt.vBMD) and trabecular volume bone mineral density (Tb.vBMD). In bone microarchitecture, serum OC and ucOC were negatively correlative with Tb.N and Tb.BV/TV, and were positively correlated with Tb.Sp. Serum OC and ucOC were positively associated with Tb.1/N.SD. Serum OC was negatively related with Tb.Th. Serum ucOC was positively associated with ALM. The high level of serum OC was the risk factor of osteoporosis. ALM was the protective factor for osteoporosis. All forms of serum OC were negatively associated with BMD. Serum OC and ucOC mainly influenced microstructure of trabecular bone in peripheral skeletons. Serum ucOC participated in modulating both bone microstructure and muscle mass.

Rapamycin does not alter bone microarchitecture or material properties quality in young-adult and aged female C57BL/6 mice.

Advancing age is the strongest risk factor for osteoporosis and skeletal fragility. Rapamycin is an FDA-approved immunosuppressant that inhibits the mechanistic target of rapamycin (mTOR) complex, extends lifespan, and protects against aging-related diseases in multiple species; however, the impact of rapamycin on skeletal tissue is incompletely understood. We evaluated the effects of a short-term, low-dosage, interval rapamycin treatment on bone microarchitecture and strength in young-adult (3 mo old) and aged female (20 mo old) C57BL/6 mice. Rapamycin (2mg/kg body mass) was administered via intraperitoneal injection 1×/5d for a duration of 8wk; this treatment regimen has been shown to induce geroprotective effects while minimizing the side effects associated with higher rapamycin dosages and/or more frequent or prolonged delivery schedules. Aged femurs exhibited lower cancellous bone mineral density, volume, trabecular connectivity density and number, higher trabecular thickness and spacing, and lower cortical thickness compared to young-adult mice. Rapamycin had no impact on assessed microCT parameters. Flexural testing of the femur revealed that both yield strength and ultimate strength were lower in aged mice compared to young-adult mice. There were no effects of rapamycin on these or other measures of bone biomechanics. Age, but not rapamycin, altered local and global measures of bone turnover. These data demonstrate that short-term, low-dosage interval rapamycin treatment does not negatively or positively impact the skeleton of young-adult and aged mice.

Особенности современных методов диагностики остеопороза (обзор литературы)

Abstract. Currently, osteoporosis is one of the most common diseases that significantly reduce the quality of life of patients, leading to their disability and death from related complications. The growing prevalence of osteoporosis in the population over the years, both among people over 60 years of age and among children under 18 years of age, as well as the high prevalence of osteoporotic fractures and their projected increase, requires improvement in the organization of care for patients, which primarily implies timely diagnosis with determination of the risk of low-energy fractures and timely treatment. Purpose: based on an analysis of the literature, to evaluate the current state of the problem and the effectiveness of modern methods for diagnosing osteoporosis. Materials and methods: a search was conducted in the open electronic scientific databases PubMed and the databases of the Russian scientific electronic library eLibrary using keywords and phrases: osteoporosis, osteodensitometry, bone mineral density, osteoporotic fracture. The results were obtained using the equipment of the Center for Collective Use of Scientific Equipment at Derzhavin Tambov State University. Results. The research presents data on risk factors for osteoporosis, possible clinical manifestations and existing methods for diagnosing this disease, indicating the advantages and disadvantages of each of the presented methods. The standard research method, if there is reason to assume a diagnosis, will be osteodensitometry. Ultrasound osteodensitometry serves as an indirect method for assessing bone tissue density. To determine bone mineral density it is recommended to use single energy X-ray absorptiometry (SXA), dual energy X-ray absorptiometry (DXA), radiographic absorptiometry (RA) and quantitative computed tomography. The standard radiographic method of radiation visualization of bone structures is the most accessible and widespread in the Russian Federation; however, for the purpose of diagnosing osteoporosis, this technique in most cases is not the method of choice, since radiographs can reveal reliable, but rather late signs of this disease. Conclusion. Each of the diagnostic methods has its own individual advantages, unique to it; to identify this disease in the early stages of its development, there is a need to use several methods for quantitative determination of bone density simultaneously.

Osteoporosis in psoriatic arthritis: Risk factors, insufficiency fractures and its association with the disease activity

ObjectiveThe prevalence of osteoporosis (OP) and insufficiency fractures in psoriatic arthritis (PsA) remains controversial. The aim of this study was to describe the prevalence of OP and insufficiency fractures in a representative cohort of patients with PsA, and to analyse its association with general risk factors and characteristics of the psoriatic disease in our geographical area. MethodsMulti-centric, descriptive study of patients with PsA. We recorded clinical characteristics, as well as protective and risk factors for OP and insufficiency fractures. Hip and lumbar densitometry and lateral X-ray of the spine were evaluated. Descriptive statistics for OP and risk factors were calculated. The patients with OP were compared to those without by univariate analyses, and results were adjusted by age and sex. The association of OP and fractures with clinical characteristics was analysed by logistic regression. Results166 patients (50 men; 116 women) were included. OP was present in 26.5%, and it was more frequent in women and patients above 50 years old. Insufficiency fractures occurred in 5.4% of the total sample. In the logistic regression, OP was associated with age over 50 [OR 3.7; 95% CI (1.2–11.6); p=.02]. No association with clinical parameters was found. The most frequent risk factors among patients with OP were vitamin D insufficiency, sedentary behaviour, low calcium intake, and active smoking. In the logistic regression, OP was associated with early menopause [OR 11.7; 95% CI (1.29–106.0); p=.029] and sedentary behaviour [OR 2.3; 95% CI (1.0–5.2); p=.049]. ConclusionsIn patients with PsA, OP is more frequent in women and patients over 50 years old. A sedentary lifestyle and early menopause may add extra risk for OP. Type, duration disease, and treatments are not associated with OP or insufficiency fractures.

Prevalence of Common Metabolic Bone Diseases Diagnosed by Dual-Energy X-Ray Absorptiometry Scanning and Blood Test in Outpatients With Osteoarthritis the Knee.

Osteoarthritis of the knee (OA knee) is a common geriatric disease that require total knee arthroplasty. Periprosthetic fracture is one of the common complications, which is strongly related to metabolic bone disease. We conducted a prospective study on 291 outpatients with OA knee between November 2020 and April 2021. Baseline characteristics, dual-energy X-ray absorptiometry and blood test results were analysed using logistic regression analysis and expressed as odds ratio, 95% confidence intervals and P-values. Overall metabolic bone diseases were found in 82.91% of patients. Vitamin D insufficiency (53.38%) was the most prevalent, followed by osteopenia (44.38%), impaired renal function (26.69%), and osteoporosis (17.45%). Risk factors of vitamin D insufficiency are age ≥71 years (OR 0.33, P = 0.003) and bilateral affected side (OR 1.99, P = 0.007). For osteopenia and osteoporosis, risk factors were age, body mass index, affected side, and chronic kidney disease (P < 0.05). In the aspect of Vit D insufficiency, age>70 and bilateral OA knee were significantly related in many ways, such as reduction in cutaneous synthesis and daily exposure to sunlight and various diseases, including CKD and GI malabsorption. The risk factors of osteopenia and osteoporosis can be explained throughout several mechanisms. For instance, abnormality in hormone and cytokines metabolism will lead to the increase in adipocyte differentiation and fat accumulation. And that situation may lead to the decrease in osteoblast differentiation and increased osteoclast activity which could lead to negative impact on bone strength. Metabolic bone diseases were common in most patients with OA knee, and the insufficiency in amount of vitamin D(serum 25-hydroxyvitamin D), osteoporosis, and osteopenia conditions were mainly identified. These preventable conditions have risk factors that are mostly correctable These preventable conditions have risk factors that are mostly correctable, for example gain more outdoor activities, consume vitamin D supplement or start osteoporosis treatment program. Further analysis is necessary to establish solid evidence in the comparison of risk factors between the OA and non-OA groups.

Knowledge, Attitudes, and Practices of Patients with Knee Osteoarthritis Regarding Osteoporosis and Its Prevention: A Cross-Sectional Study in China.

Older age and female sex are risk factors for osteoarthritis and osteoporosis (OP). This study evaluated the knowledge, attitudes, and practices of patients with knee osteoarthritis (KOA) in China regarding OP and its prevention. This cross-sectional, questionnaire-based study enrolled patients with KOA at four grade-A tertiary hospitals in Shandong Province between 1st September and 20th November 2022. The administered questionnaire contained 55 items across four dimensions (demographic information, knowledge, attitude, and practice). Logistic regression analyses were performed to identify factors associated with an overall questionnaire score ≥70% of the maximum possible score. SPSS 26.0 was used for the analyses; P<0.05 was considered significant. The analysis included 434 participants (261 females). The median knowledge, attitude, and practice scores were 7 (interquartile range: 5-10) (possible range, 0-17 points), 44 (interquartile range: 42-49) (possible range, 11-55 points), and 43 (interquartile range: 38-47) (possible range, 13-65 points), respectively. Multivariable logistic regression indicated that female sex (odds ratio [OR], 2.421; 95% confidence interval [95% CI] 1.558-3.762; P<0.001), age 56-65 years-old (OR, 4.222; 95% CI, 1.763-10.109; P=0.001 vs ≤55 years-old), age >65 years-old (OR, 4.358; 95% CI, 1.863-10.195; P=0.001 vs ≤55 years-old), middle/high/technical secondary school education (OR, 1.853; 95% CI, 1.002-3.428; P=0.049 vs primary school or below), and having KOA for 4-5 years (OR, 2.682; 95% CI, 1.412-5.094; P=0.003 vs ≤3 years) were independently associated with a high KAP score. There is room for improvement in the knowledge and practices of patients with osteoarthritis in China regarding OP. The findings of this study may facilitate the design and implementation of education programs to increase awareness about OP prevention among patients with KOA.

Osteoporosis in Chronic Obstructive Pulmonary Disease

The common risk factors for Chronic Obstructive Pulmonary Disease (COPD) and Osteoporosis are age, smoking and inactivity

Денситометрическая оценка минеральной плотности костной ткани у пациентов молодого возраста с лимфомой Ходжкина

Hodgkin’s lymphoma is more often diagnosed in young patients. One of the late complications of pathogenetic therapy of Hodgkin’s lymphoma is osteopenia/osteoporosis and the increased risk of low-energy fractures. Conducting densitometry in young patients in order to assess the bone tissue condition is advisable, but its clinical assessment remains difficult. At the same time, early diagnosis and prevention of bone mineral density decrease in patients with Hodgkin’s lymphoma who received antitumor therapy are very relevant. The purpose — to study the features of densitometric indicators for the verification of osteopenia / osteoporosis in young patients with Hodgkin’s lymphoma. Material and methods. 63 people were included in the study, 33 of them were patients with Hodgkin’s lymphoma who received pathogenetic therapy, and 30 people the control group — healthy volunteers. Bone mineral density was measured in all patients using the HOLOGIC (Hologic Inc., Bedford) in the lumbar spine (L1–L4) and in the hip area (the total area of the hip and hip neck). Criteria such as minimum bone mineral density, T-criteria and Z-criteria for young patients with Hodgkin’s lymphoma were determined. Results. In the group of patients with Hodgkin’s lymphoma, a decrease in bone mineral density is significantly more often recorded in all measurement areas, as well as the Z-criterion in the lumbar spine. Regretfully, in young patients the T-criterion can only be used given a more intensive mineralization of bone tissue than in older people and the presence of additional risk factors for osteoporosis (PCTs, glucocorticosteroids, decreased androgenic and fertile function). In patients with HL who received pathogenetic therapy, a decrease in the T-criterion to osteopenia is more often observed in the proximal femur. Conclusion. In many cases, modern capabilities for osteoporosis diagnostic allow correcting mineral metabolism in bone tissue and preventing the development of complications in young patients with Hodgkin’s lymphoma.

Investigating β Thalassemia Patients and Their Growth: A Brief Review and Our Clinical Experience

Background: The prevalence of short stature was reported high in thalassemia major patients. It causes mental and social problems for them. As different cut-off points for growth retardation are suggested in these patients, it is desirable to find a careful cut-off age using statistical analysis to help patients before it is too late. Methods: Data from 803 thalassemia major patients was extracted from questionnaires completed in person by the operator. They contained demographic data, family, medical, and drug history. Height and weight measurements were conducted by only one device. The mean age was 20±7 years and there were 420 females in the sample. Children (&lt;20 years of age) constituted 47% of the participants. Patients who reported a major risk factor for osteoporosis were omitted from this study. The SPSS software, version 16 was used for the statistical analysis Results: Short stature was found in 32% of patients. Being 10 to 11 years old or above increased the risk of short stature, 28.5 and 21.4 times, respectively compared to younger patients (P&lt;0.001). On the other hand, after 7 years of age up to 18 years of age, similar to 10 years of age and 11 years of age, increases the risk of short stature. Also being 27 years old and 30 years old and above increases the risk of short stature 1.4 and 1.7 times, respectively, compared to younger patients (P=0.042 and &lt;0.018, respectively). Conclusions: Awareness of short stature and monitoring it in thalassemic patients should be done in their childhood. Accordingly, being 7 years old or above increases the risk of short stature; therefore, we suggest the start of monitoring as early as 5 years of age.

The Level of Knowledge, Awareness, and Practice Regarding Osteoporosis among Female Adults in Hail city, Saudi Arabia

This is a cross-sectional study conducted on the adult female population of Hail city. Informed consent was obtained from the participants through the electronic survey. The sample size needed to enroll was 384, estimated from the total female population of Hail city 267,113 by Raosoft sample size calculator, with a 95% confidence interval and 5% margin of error (General Authority for statistics). All Saudi females in Hail city constituted the study population. However, all non-Saudi females and males, Saudi or otherwise, were excluded from the study population. We used the Osteoporosis Knowledge Assessment Tool (OKAT) which was pre-validated, translated to Arabic, and self-answered questionnaire. The OKAT survey is a valid measurement of knowledge of risk factors for osteoporosis, (Tania M Winzenberg et al, 2003). It consists of 20 statements; the first 12 assess the knowledge of osteoporosis, 4 questions assess the attitude towards osteoporosis and the last 4 questions assess the preventive factors of osteoporosis. Each statement has three choices, true, false, and I do not know. The OKAT survey was translated into Arabic language which is found to be reliable and acceptable according to Sayed-Hassan et al. The questionnaire was distributed randomly through social media platforms during the period from March to May 2020. Keywords: Knowledge, awareness, practice, osteoporosis, Saudi Arabia

Оптимизация восстановления костной ткани у больных ревматоидным артритом и остеопорозом, осложненным переломами

The article provides a brief summary of bone remodeling, including its stages, disorders, and correction. Osteoporosis (OP) is a systemic skeletal disease in which bone resorption predominates over bone formation. OP is characterized by a decrease in bone mass and density, as well as a disturbance of bone microarchitecture. This leads to a decrease in bone strength and an increased risk of fractures. This paper describes a case of a woman with rheumatoid arthritis (RA) and OP complicated by low-trauma fractures. The authors emphasize that OP is a multifactorial disease and one of the most common bone diseases, particularly among the elderly. OP in RA is an immune- mediated secondary osteopathy and is considered both a comorbidity and complication of the underlying disease. Patients with RA have a higher bone mineral density (BMD) and a higher rate of fractures than the general population. Fractures can occur in individuals with osteopenia or normal BMD values. Therefore, it is important to carefully analyze the risk factors for OP and fractures when planning RA therapy. The ‘treat to target' strategy aims to achieve RA remission or reduce disease activity while also preventing complications, such as osteoporotic fractures. To manage bone metabolism disorders in patients with RA who also have osteoporosis and fractures, it is necessary to control RA activity and prescribe basic therapy for osteoporosis, such as ossein-hydroxyapatite complex and alfacalcidol, as well as pathogenic drugs that prevent bone resorption. Additionally, patients with osteoporosis and fractures require pain-reducing measures, restorative treatment, and rehabilitation. Effective management requires a multidisciplinary approach involving physicians from various specialties.
