Assessment of Quality of Life and Pain Severity in Older Men with Osteoporosis: Cross-Sectional Study

Association between serum soluble α-klotho and bone mineral density (BMD) in middle-aged and older adults in the United States: a population-based cross-sectional study

BACKGROUND

Osteoporosis is a degenerative disease defined by low bone mineral density, has a high prevalence, and causes fractures at multiple sites throughout the body, greatly affecting the quality of patients. α-Klotho is an endocrine factor involved in the regulation of various metabolic processes in humans, and its role in bone metabolism has attracted widespread attention. The relationship between α-klotho and bone mineral density has not been uniformly recognized, and no large-scale correlation analysis has been conducted in the middle-aged and elderly population.

OBJECTIVE

To determine the relationship between α-klotho and bone mineral density in middle-aged and elderly people.

METHODS

Population data of 3120 individuals aged 40-79 years were obtained from the NHANES database for the period 2011-2016. Regression analysis was performed using a general linear model with serum α-klotho as the independent variable and total bone mineral density, thoracic bone mineral density, lumbar bone mineral density, pelvic bone mineral density, and trunk bone mineral density as the dependent variables, respectively. The generalized additive model was also used for smoothing curve fitting and threshold effect analysis.

RESULTS

Serum α-klotho was positively correlated with total bone mineral density at lg (Klotho) < 2.97 and with thoracic bone mineral density at lg (Klotho) > 2.69 (β = 0.05, p = 0.0006), and negatively correlated (β = -0.27, p = 0.0341) with lumbar bone mineral density at lg (Klotho) < 2.69. It also positively correlated with trunk bone mineral density (β = 0.027, p = 0.03657) and had no segmental effect but did not correlate with pelvic bone mineral density. The positive association of serum α-klotho with those aged 40-49 years, female, non-Hispanic White, and without hypertension was clearer. In the population with diabetes, a significantly positive association between total (β = 0.15, p = 0.01), thoracic (β = 0.23, p = 0.0404), and lumbar (β = 0.22, p = 0.0424) bone mineral density and α-klotho was observed.

CONCLUSIONS

α-Klotho has different relationships with total, thoracic, lumbar, and trunk bone mineral density. Among them, the positive correlation between α-klotho and trunk bone mineral density is more valuable for predicting osteoporosis. The significant effect of α-klotho on bone mineral density in diabetes patients suggests its potential as a predictive marker of diabetes progression.

Impact of Cross-Linking Procedure on Perioperative Quality of Life in Keratoconus Patients

BACKGROUND

To evaluate the effect of crosslinking (CXL) with riboflavin for keratoconus (KC) therapy on quality of life (QoL): comparison of keratoconus patients with and without treatment.

METHODS

Prospective monocentric study. We recruited patients with progressive KC and with stable disease. Patients with progressive disease received cross-linking treatment; patients with stable disease were monitored. We compared QoL in both groups over 6 months and detected the influence of cross-linking treatment on QoL. QoL was assessed by NEI-VFQ-25, EQ-5D 5L, and EQ-Visual analog scale (VAS). In the evaluation of the Nei VFQ, the subgroups LFVFS and LFSES were calculated.

RESULTS

We enrolled 31 eyes of 31 patients in the intervention group and 37 eyes of 37 patients in the control group. Medians with standard deviations (SD) were calculated. All QoL-tests showed equal scores at baseline in both groups. At V2, one day after the treatment, EQ-VAS (56.4), LFVFS (57.4), and EQ5D5L (0.59) were significantly reduced. At V3 (one week after treatment), all results returned to baseline level. LFSES was not affected by the treatment. It remained stable (V2 85.4, V3 84.3). Comparing the baseline scores with the follow-up scores at month 6, we found a significant increase in QoL in all tests in the intervention group. Otherwise, the quality of life in the control group did not change over time.

CONCLUSIONS

Cross-linking led only to a short-term reduction in QoL. Although the treatment is painful for a few days, no effect on general quality of life LVSES has been demonstrated. QoL already returned to baseline after one week and the patients were not limited anymore.

Health-related quality of life of men with primary osteoporosis and its changes after bisphosphonates treatment

INTRODUCTION

Osteoporosis leads to more serious consequences in men than in women, but less is known about its impacts on health-related quality of life (HRQoL) of men, and whether the anti-osteoporosis treatment can improve HRQoL of men with osteopenia/osteoprosis.

METHODS

We enrolled men with primary osteoporosis and age-matched healthy controls. We collected medical history, serum levels of carboxyl-terminal type I collagen telopeptide, procollagen type I propeptides, and bone mineral density of patients. All patients and controls completed the short-form 36 (SF-36) questionnaires. Changes in HRQoL of osteopenia/osteoporosis men were prospectively evaluated after alendronate or zoledronic acid treatment.

RESULTS

A total of 100 men with primary osteoporosis or osteopenia and 100 healthy men were included. The patients were divided into three subgroups: osteopenia (n = 35), osteoporosis (n = 39) and severe osteoporosis (n = 26). Men with osteoporosis or severe osteoporosis had impaired HRQoL in domains of physical health compared to healthy controls. HRQoL scores in physical health related domains of patients with severe osteoporosis were significantly lower compared to healthy controls, and were the poorest among the three subgroups of patients. Fragility fracture history was correlated with lower SF-36 scores about physical health. In 34 men with newly diagnosed osteoporosis receiving bisphosphonates treatment, HRQoL scores were significantly improved in domains of physical health after treatments.

CONCLUSIONS

The HRQoL is significantly impaired in men with osteoporosis, and the more severe the osteoporosis, the poorer the HRQoL. Fragility fracture is an important influencing factor of deteriorated HRQoL. Bisphosphonates treatment is beneficial to improve HRQoL of osteopenia/osteoporosis men.

Dietary Behaviors, Serum 25(OH)D Levels and Quality of Life in Women with Osteoporotic Disorders

Data obtained in recent years clearly demonstrate the aging process of European populations. Consequently, the incidence of osteoporosis has been rising. The aim of this study is to assess the quality of life (QoL) of women with osteoporosis. A total of 260 women participated in this study. The patient group consisted of 170 women with osteoporotic disorders. The control group consisted of 90 healthy women. Participants' quality of life was measured with the Qualeffo-41 Questionnaire. The total 25(OH)D concentration level was assessed with an assay using the chemiluminescent immunoassay. To assess the pain level, the Visual Analogue Scale (VAS) was used. To assess dietary behaviors, data were obtained by a 13-item Food Frequency Questionnaire. To assess the nutrition knowledge of participants, the Beliefs and Eating Habits Questionnaire was used. Based on the frequency of food intake, participants were classified into three patterns of behavior, i.e., Prudent, Western, and Not Prudent-Not Western. The patients assessed their quality of life as average (36.6 ± 19.9 points). The most favorable scores were obtained in the domains of "Ability to do jobs around the house" and "Mobility". The worst rated domain among the respondents was "Mental function". There were significant differences identified in quality of life depending on diet, nutritional knowledge, comorbidities and occurrence of fractures in the subjects. The individuals in the "Prudent" group reported a significantly higher quality of life as compared to the "Not Prudent-Not Western" and "Western" groups and those with high nutritional knowledge as compared to those with moderate and low. Lower quality of life was also observed among women with comorbidities and with bone fractures. Depending on serum 25(OH)D levels, poorer quality of life was characterized women with vitamin D deficiency. Patient education, implementation of effective methods aimed at alleviating pain and maintaining the optimal concentration of vitamin D can help improve the quality of life in patients with osteoporotic disorders.

Assessment of the Quality of Life of Women after Osteoporotic Vertebral Fracture with Consideration of Socio-Demographic Characteristics and Selected Factors Concerning the State of Health

Introduction: Fractures of the vertebral bodies are a frequent complication of osteoporosis, hospitalization, decline in physical fitness and, in consequence, deterioration in the quality of life. Objective: The aim of the study was assessment of the quality of life according to the QUALEFFO-41 questionnaire in patients who had undergone fractures of the vertebral bodies, and presentation of the relationships between the quality of life, socio-demographic characteristics, and selected factors concerning the state of health. Materials and Method: The study included 243 women with osteoporotic vertebral fractures, and was conducted in the Outpatient Departments for the Treatment of Osteoporosis in the city of Lublin (eastern Poland). For the purposes of the study, the Quality of Life Questionnaire (QUALEFFO-41) and the author's questionnaire were employed, and Spearman's rank correlation coefficient, t-Student test, and Tukey test were used, along with analysis of variance (ANOVA). The level of statistical significance was set at α = 0.05. Results: The quality of life of woman with vertebral compression fractures remains on a mediocre level. Significant relationships were observed between the respondents' quality of life and certain socio-demographic characteristics, duration of the disease, and complaints related with osteoporosis. Conclusions: It is important to implement appropriate therapy and provide comprehensive, holistic care to women after fractures.
