Objective. To investigate the relationship between neutrophil to lymphocyte ratio (NEU/LY), monocyte to lymphocyte ratio (MO/LY), platelet to lymphocyte ratio (PLT/LY), mean platelet volume to lymphocyte ratio (MPV/LY), mean platelet volume to platelet ratio (MPV/PLT), plateletcrit to platelet ratio (PCT/PLT) and postmenopausal osteoporosis. Materials and Methods. The data of the patients who were admitted to Ümraniye Training and Research Hospital between January 2017 and July 2020 and had both bone mineral densitometry and hemogram tests on the same day were retrospectively scanned. A number of 177 patients who had been in natural menopause for at least one year and did not have any chronic disease nor used any medication were first divided into 3 groups: a number of 48 patients with osteoporosis, 103 with osteopenia and 26 patients included in the control group. Later on, 177 patients were divided into two groups: 151 patients with low bone mineral density and 26 patients were included in the control group. Results. There was no difference between the three groups in terms of NEU/LY, MPV/LY, MPV/PLT and PCT/PLT. The MO/LY ratio and PLT/LY ratio were statistically significantly higher in the osteoporosis group (p = 0.002, p <0.001, respectively). The MO/LY ratio was significantly higher in the group with low bone mineral density compared to the control group (p = 0.011), while there was no statistical difference between the two groups in terms of PLT/LY ratio (p = 0.281). Conclusions. This study shows that MO/LY and PLT/LY are quite simple and cheap markers that can be used in the diagnosis of postmenopausal osteoporosis and MO/LY in the diagnosis of postmenopausal low bone mineral density.

Inflammatory Status

Objectives: Postmenopausal osteoporosis is a progressive metabolic bone disease resulting from estrogen deficiency. However, due to the silent nature of the disease, there is an urgent need for a simple, early predictive marker. This study, conducted between January 2017 to December 2019, aimed to assess the potential of three factors—specifically, the neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR)—as inflammatory markers of bone mineral density (BMD) loss. Methods: A retrospective cross-sectional study was conducted among 450 postmenopausal Omani women undergoing dual-energy X-ray absorptiometry at the Sultan Qaboos University Hospital, Muscat, Oman. Participants were allocated into groups based on lumbar spine BMD t-score values. A receiver-operating characteristic curve was used to find the area under the curve (AUC). Multivariate logistic regression was performed to identify independent predictors of low BMD. Results: A total of 65 (14.4%), 164 (36.4%), and 221 (49.1%) women were allocated to the control, osteopenia, and osteoporosis groups, respectively. No significant differences in PLR, MLR, and NLR values were observed based on group allocation. BMD t-score values were reversely correlated with age (P = 0.007) and PLR (P = 0.004), and positively correlated with body mass index (BMI) (P <0.001). The AUC was 0.59. However, the only independent predictors of low BMD were age (>65 years) and BMI (<25 kg/m2). Conclusion: None of the three inflammatory biomarkers studied were found to be useful prognostic indicators of bone loss. Further research is recommended to reject or support theories regarding the role of inflammatory status in the pathogenesis.

AbstractObjective:There is evidence for a strong correlation between low bone mineral density and hearing loss. Furthermore, premature hair greying has been associated with low bone mineral density. Hence, this study aimed to investigate, for the first time, the relationship between premature hair greying and hearing impairment.Methods:Fifty patients with premature hair greying (20 women and 30 men), aged under 40 years (mean, 30.1 ± 4.9 years), who had onset of hair greying in their twenties, were recruited, along with 45 age- and sex-matched healthy control subjects (17 women and 28 men; mean age, 28.7 ± 5.1 years). Each participant was tested with low frequency audiometry at 0.125 to 2 kHz, high frequency audiometry at 4 to 8 kHz, and extended high frequency audiometry at 9 to 20 kHz.Results:Hearing thresholds were similar at all frequencies from 0.25 to 4 kHz (p > 0.05); however, significant hearing loss was observed at all frequencies from 8 to 20 kHz in the premature hair greying group compared with the control group (p < 0.05).Conclusion:Patients with premature hair greying had hearing impairment at extended high frequencies. Premature hair greying may be an important risk factor for hearing loss.

As women go through menopause, serum estrogen decreases, and ferritin increases. Ferritin is an essential component of the body, but many studies have stated that ferritin, which exceeds the normal physiological range, may potentially cause health problems in women. The aim of this study is to investigate the relationship between bone mineral density and serum ferritin levels in post-menopausal women and to evaluate serum ferritin levels as a potential biomarker for postmenopausal osteoporosis. Serum ferritin levels were measured in 62 postmenopausal women with low bone mineral density, and in 18 postmenopausal healthy control women using a standardized Enzyme-Linked Immune Sorbent Assay (ELISA) kit. Bone mineral density BMD was assessed at the lumbar spine and femoral neck. The mean serum ferritin level was significantly higher in the postmenopausal women with low BMD group (group 1) than in the normal control group (group 2), respectively (mean=262.69 vs. 181.44 ng/ml, (P<0.05), and serum ferritin level was negatively correlated with BMD among low BMD postmenopausal women's group (R= -0.628, P=0.0001), and in the healthy postmenopausal group (R= -0.052, P=0.838). A comparison of the BMD between spine and femur neck sites shows that the frequency of low BMD in the spine site is higher than the femur neck site. Our findings show that increased serum ferritin levels were associated with low bone mineral density in postmenopausal osteoporosis.

Background and Objective. Variation of osteoporosis in the population is the result of an interaction between the genotype and the environment, and the genetic causes of osteoporosis are being widely investigated. The aim of this study was to analyze the association between the polymorphisms of the vitamin D receptor (VDR), type I collagen (COL1A1), and lactase (LCT) genes and severe postmenopausal osteoporosis as well as bone mineral density (BMD). Material and Methods. A total of 54 women with severe postmenopausal osteoporosis and 77 controls (mean age, 58.3 years [SD, 6.2] and 56.7 years [SD, 7.42], respectively) were included into the study. The subjects were recruited at the City Center for Osteoporosis Prevention (Minsk, Belarus). Dual-energy x-ray absorptiometry was used to measure bone mineral density at the lumbar spine and the femoral neck. Severe osteoporosis was diagnosed in the women with the clinical diagnosis of postmenopausal osteoporosis and at least 1 fragility fracture. The control group included women without osteoporosis. Polymorphic sites in osteoporosis predisposition genes (ApaI, BsmI, TaqI, and Cdx2 of the VDR gene, G2046T of the COL1A1 gene, and T-13910C of the LCT gene) were determined using the polymerase chain reaction on the deoxyribonucleic acid isolated from dried bloodspots. Results. The data showed that the ApaI and BsmI polymorphisms of the VDR gene and T- 13910C of the LCT gene were associated with severe postmenopausal osteoporosis in the analyzed Belarusian women (P<0.01). A statistically significant positive correlation between the VDR risk genotypes ApaI and TaqI and bone mineral density was found (P<0.05). Conclusions. The findings of this study suggest that at least the ApaI and BsmI polymorphisms of the VDR gene and T-13910C of the LCT gene are associated with the risk of postmenopausal osteoporosis in our sample of the Belarusian women.

Low Bone Mineral Density

Chronic inflammation affects bone metabolism and accelerates bone loss. This study is aimed at analyzing the prevalence of low bone mineral density (LBMD) in patients with untreated Takayasu’s arteritis (TA) and risk factors. Forty untreated TA patients were enrolled, including 38 premenopausal women and 2 men before 50 years old. The control group included 60 age- and gender-matched healthy persons. Bone mineral density (BMD) of lumbar vertebrae and hip in patients with TA and the control group was measured by the dual-energy X-ray method. Serum 25OHD and β-CTX were also measured. The lumbar BMD of TA patients ( 0.89 ± 0.11  g/cm2) was significantly lower than that of the healthy control ( 0.97 ± 0.11  g/cm2). The prevalence of LBMD at the lumbar spine (17.50%) was significantly higher than that of the control group (3.33%). However, there was no significant difference at the hip. The 25OHD of TA patients was lower than that of healthy controls, while the level of β-CTX was higher. The levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) in patients with LBMD were higher than those in patients with normal BMD. According to univariate correlation analysis, there was a significant negative correlation between LDL-C and lumbar BMD. Binary logistic regression analysis showed that LDL-C was an important factor affecting the occurrence of LBMD in patients with TA ( OR = 25.269 , P = 0.02 ). Our result reveals bone loss in TA patients, which hints the relationship among inflammation, lipid metabolism, and bone metabolism.

Cross Sectional Studies

Abstract Context: HIV infection has been associated with low bone mineral density (BMD) in many cross-sectional studies, although longitudinal studies have not demonstrated accelerated bone loss. The cross-sectional studies may have been confounded by the failure to control for low body weight in HIV-infected patients. Objective: Our objective was to determine whether low body weight might explain the association of HIV infection with low BMD. Data Sources: MEDLINE and EMBASE were searched for English language studies published from 1966 to March 2007, and conference abstracts prior to 2007 were hand-searched. Study Selection: All studies reporting BMD and weight or body mass index in adult patients with HIV and a healthy age- and sex-comparable control group were included. Nine of 40 identified studies and one of 68 identified abstracts were eligible. Data Synthesis: We adjusted for the between-groups weight differences using regression coefficients from published cohorts of healthy men and women. On average, HIV-infected patients were 5.1 kg [95% confidence interval (CI), −6.8, −3.4; P &lt; 0.001] lighter than controls. At all skeletal sites, unadjusted BMD was lower by 4.4–7.0% in the HIV-infected groups than the controls (P &lt; 0.01). After adjustment for body weight, residual between-groups differences in BMD were small (2.2–4.7%) [lumbar spine, −0.02 (95% CI, −0.05, 0.01) g/cm2; P = 0.12; total hip, −0.02 (95% CI, −0.04, 0.00) g/cm2; P = 0.031; femoral neck, −0.04 (95% CI, −0.07, −0.01) g/cm2; P = 0.013; and total body, −0.03 (95% CI, −0.07, 0.01) g/cm2, P = 0.11]. Conclusion: HIV-infected patients are lighter than controls and low body weight may largely account for the high prevalence of low BMD reported in HIV-infected patients. However, in the setting of current treatment practice, HIV infection per se is not a risk factor for low BMD.
