ABSTRACT

Objective:To investigate the diagnosis of dual-energy X-ray absorptiometry(DXA)for osteoporosis(OP)of postmenopausal patients with rheumatoid arthritis(RA)in Qinghai region and the risk factors of them.Methods:A total of 200 postmenopausal female RA patients who admitted to Qinghai Hospital of Traditional Chinese Medicine from May 2022 to April 2023 were selected.All patients were tested for bone mineral density(BMD)after admission,and lumbar spines L1-L4,whole lumbar,large trochanter,Ward's triangle area,whole body and whole forearm were measured by DXA.According to the results of BMD test,patients whose BMD T values of all body parts-2.5 SD were less or equal to-2.5 were included in the OP group(121 cases),and patients whose BMD T value of all body parts were larger than-2.5 SD were included in the non-OP group(79 cases).The BMD T value of different body parts between two groups of RA patients were compared and analyzed.The area under curve(AUC)of receiver operating characteristic(ROC)curve was used to analyze the diagnostic efficiency of BMD T value for OP.The logistic regression method was adopted to analyze the risk factors that postmenopausal RA patients of Qinghai region occurred OP.Results:The BMD T values of L1,L2,L3,L4,whole lumbar,large trochanter,Ward's triangular area,whole body and whole forearm of OP group were obviously lower than those of the non-OP group.In analysis of ROC curve,the sensitivities of BMD T values of L1,L2,L3,L4,whole lumbar,large trochanter,Ward's triangle area,whole body and forearm were respectively 96.20%,95.22%,90.16%,96.03%,92.01%,89.36%,99.26%,90.02% and 96.03% in diagnosing OP,and the specificities of them were respectively 81.00%,82.19%,85.22%,83.06%,83.06%,90.22%,80.06%,86.23%,83.09%,and the AUC values of them were respectively 0.908,0.905,0.896,0.906,0.903,0.879,0.918,0.901 and 0.906.The results of the logistic-regression analysis showed that advanced age,long disease course,rheumatic activity scores of 28 joints,erythrocyte sedimentation rate and Calcium supplementation were the risk factors of occurring OP in postmenopausal RA patients in Qinghai region.Conclusion:The DXA method that detects BMD of RA patients who occur OP can be used as gold standard to assess OP,and there are many risk factors that affect the occurrence of OP in postmenopausal RA patients of Qinghai region.The clinical work should combine with relative factors to formulate reasonable measure so as to reduce the incidence of OP.

ABSTRACT

Objective To investigate the present state of mineral metabolism and its related factors in elderly patients with maintenance hemodialysis (MHD),in order to improve the quality of life and survival rate in elderly patients with MHD in Xinxiang.Methods Clinical data of 466 patients with treatment of MHD for over 3 months in 4 hospitals in Xinxiang district were enrolled from January 2012 to August 2013 in this study,and the patients were divided into the elderly group (n=159,aged ≥ 60 years) and the non-elderly group (n =307,aged < 60 years).The evaluation indexes for mineral metabolism were determinated,such as serum levels of calcium,phosphorus,intact parathyroid hormone (iPTH) and alkaline phosphatase (ALP).The present state of mineral metabolism and its relationships with anemia,dialysis ages,adequacy of dialysis,malnutrition and inflammatory factors were analyzed in elderly patients with MHD.Results Among 466 patients,the serum levels of calcium,phosphorus and iPTH in MHD patients were (1.95 ± 0.34) mmol/L,(2.54±1.38) mmol/L and (409.5±345.6) ng/L respectively,and their control rates were 34.3%,20.4% and 25.5% respectively.And in patients with hemodialysis three times a week,the control rates were 50.8%,31.4% and 32.2% respectively.The serum levels of phosphorus,iPTH,ALP,albumin and transferrin saturation were lower in elderly group than in non-elderly group (all P<0.01),and the serum levels of pre-albumin,hemoglobin and feritin were lower in elderly group than in non-elderly group (all P<0.05).But the serum levels of calcium and C-reactive protein (CRP)were higher in elderly group than in non-elderly group (all P<0.05).Conclusions The elderly patients with MHD exhibit unique clinical manifestations of abnormal mineral metabolism,and low bone transformation osteopathy is the main manifestation.The micro-inflammation,malnutrition and anemia are more severe in elderly patients than in non elderly patients.
