A Comparison of Bone Mineral Density in Elderly Female Patients with COPD and Bronchial Asthma.

Background : Chronic renal disease changes both quality and quantity of bone through multifactorial influences on bone metabolism, leading to osteopenia, osteoporosis and increased risk of fracture. The objectives of this cross sectional study are to determine the mean bone mineral density (BMD) and to identify osteopenia and osteoporosis in patients of CKD on maintenance hemodialysis. Methods: Twenty three male and 18 female patients with age between 18 and 50 years were enrolled in this study. The BMD of the lumbar vertebral spine (LV) and the neck of femur (FN) were measured in all patients. Data were analyzed using SPSS version 20.0 software and the level of significance was considered as P <0.05. Results: The mean BMD in the LV (L2-L4) was 1.18 ± 0.19 gm/cm2 in male and 1.04 ± 0.13 gm/cm2 in female patients (P =0.011). The mean BMD in the FN was 0.90 ± 0.19 gm/cm2 in male and 0.77 ± 0.15 g/cm2 in female patients (P = 0.022). Based on the World Health Organization criteria, 26.0% of the male and 22.2% of the female patients in our study had normal BMD; 39.2% male and 38.9%female patients had osteopenia, while 34.8% male and 38.9% female patients had osteoporosis .This study showed a marked decrease in mean BMD in the cortical bone (FN) compared with trabecular bone (LV) (P = 0.001) as well as in female patients on maintenance hemodialysis compared with male patients . Significant negative correlation (r= -0.480; p=0.001) was found between duration of hemodialysis and bone mineral density (BMD) in lumbar spine and femoral neck. Conclusion: The measurement of BMD is a good non-invasive screening test for renal bone disease and that a high number of patients with CKD stage 5 on maintenance hemodialysis have markedly decreased BMD.

Abstract Objectives: This study is to explore the prevalence of different stages of bone loss and the potential risk factors in rheumatic patients.Method: A cross-sectional study recruits 1,398 rheumatic patients and 302 healthy subjects. Demographic data, blood, and bone mineral density (BMD) tests are collected. Risk factors for bone loss in rheumatic patients are analyzed by logistic regression.Results: (1) Rheumatic patients are consisted of 40.0% rheumatoid arthritis (RA), 14.7% systemic lupus erythematosus (SLE), 14.2% osteoarthritis (OA), 9.2% ankylosing spondylosis (AS), 7.9% gout, 7.0% primary Sjogren syndrome (pSS), 3.8% systemic sclerosis (SSc), and 3.2% mixed connective tissue disease (MCTD). (2) In male patients aged under 50 and premenopausal female patients, the bone mineral density score of AS (53.9%, P<0.001) and SLE (39.6%, P=0.034) patients is lower than the healthy controls (18.2%). (3) Osteopenia and osteoporosis are more prevailing in male patients aged or older than 50 and postmenopausal female patients with RA (P<0.001), OA (P=0.02) and SLE (P =0.011) than healthy counterparts. (4) Those with SLE, RA and AS gain the highest odd ratio of ‘score below the expected range for age’, osteopenia and osteoporosis, respectively. (5) Age, female, low BMI and hypovitaminosis D are found negatively associated with bone loss. Dyslipidemia and hyperuricemia could be protective factors.Conclusion: Young patients with AS and SLE have a significant higher occurrence of bone loss, and older patients with RA, OA and SLE had higher prevalence than healthy counterparts. SLE, RA, SSc and AS were founded significant higher risks to develop into bone loss after adjustment. Age, BMI and gender were commonly-associated with bone loss in all age-stratified rheumatic patients. These findings were not markedly different from those of previous studies.
