Objective: We investigated the effects of testosterone replacement therapy (TRT) on bone mineral density (BMD) among hypogonadal men with osteopenia/osteoporosis.Methods: From our previous EARTH study population, 74 patients with a clinical diagnosis of osteopenia or osteoporosis and hypogonadism were included in this study, as the TRT (n?=?35) and control (n?=?34) groups. The TRT group was administered 250?mg of testosterone enanthate injection every 4 weeks for 12 months. The BMD, waist circumference, body mass index, body fat percentage, and muscle volume were measured at baseline and at 12 months. Blood biochemical data, including total cholesterol, triglycerides, HDL-cholesterol, hemoglobin A1c, and adiponectin values were also evaluated.Results: At the 12-month visit, BMD significantly increased in both groups. However, comparisons on changes of parameter values from baseline to the 12-month visit between the TRT and control groups were significantly different in BMD (5.0?±?5.0 vs. 3.0?±?3.2; p?=?.0434) and in adiponectin value (?0.90?±?3.33 vs. 0.10?±?2.04; p?=?.0192). There were no significant changes in other parameters.Conclusions: TRT for 12 months could improve BMD with a decrease in adiponectin levels among hypogonadal men with osteopenia/osteoporosis. 相似文献

Objective.?To test the relationship between gonadal status and objective measures and determinants of physical performance in older men and their determinants.Methods.?The study included 455?≥?65 year older men of InCHIANTI study, Italy, with complete data on testosterone levels, hand grip strength, cross-sectional muscle area (CSMA), short physical performance battery (SPPB). Linear models were used to test the relationship between gonadal status and determinants of physical performance.Results.?Three different groups of older men were created: (1) severely hypogonadal (N?=?23), total testosterone levels ≤230?ng /dl; (2) moderately hypogonadal (N?=?88), total testosterone >230 and?350?ng/dl) and (3) eugonadal (N?=?344), testosterone levels ≥350?ng/dl. With increased severity of hypogonadal status, participants were significantly older while their BMI was substantially similar. In the age and BMI adjusted analysis, there was a significant difference in haemoglobin levels, hand grip strength and SPPB score (p for trend?0.001) among three groups, with severely hypogonadal men having lower values of haemoglobin, muscle strength and physical performance. We found no association between testosterone group assignment and calf muscle mass and 4?m walking speed. In the multivariate analysis grip strength (p for trend?=?0.004) and haemoglobin (p for trend?0.0001) but not SPPB and other determinants of physical performance were significantly different between the three groups.Conclusions.?In older men, gonadal status is independently associated with some determinants (haemoglobin and muscle strength) of physical performance. 相似文献

Objective: To investigate associations between cardiovascular disease risk factors, including fasting glucose, cholesterol, high density lipoprotein cholesterol (HDL-c), LDL-c, blood pressure, body mass index (BMI), C-peptide, creatinine kinase, smoking, alcohol use, physical activity, C-reactive protein as well as homocysteine levels and cardiovascular events.Methods: Data from 1545 men aged ≥40?years, with testosterone deficiency (TD) (<300?ng/dL) and non-TD (≥300?ng/dL) which were extracted from the National Health and Nutrition Examination Survey database 2011–2012 and analyzed.Results: Multivariate logistic regression analysis showed positive associations between TD and BMI (≥35 vs.?18.5: OR?=?2.51, 95% CI: 1.19–5.32, p?=?.016), HDL-c (<0.91 vs. ≥0.91: OR?=?1.60, 95% CI: 1.14–2.24, p?=?.006) and diabetes (diabetes vs. non-diabetes: OR?=?1.48, 95% CI: 1.14–1.92, p?=?.004) as well as negative associations between TD and metabolic equivalent scores (≥12 vs. <12: OR?=?0.69, 95% CI: 0.52–0.91, p?=?.009) and smoking (Ever vs. never: OR?=?0.69, 95% CI: 0.51–0.94, p?=?.018). Furthermore, total serum testosterone levels were lower in patients with heart failure (p?=?.04) and angina/angina pectoris (p?=?.001) compared with subjects without these cardiac problems.Conclusion: Low serum testosterone was associated with multiple risk factors for CHD. 相似文献

AbstractEffects of testosterone (T) on the cardiovascular system of men remain controversial. The impact of T-replacement therapy (TRT) in men with functional hypogonadism and type 2 diabetes mellitus (T2DM) has to be elucidated. This study included 80 men (mean age 51.5?±?6.3 years) with newly diagnosed T2DM (according to ADA criteria) and functional hypogonadism (according to EAU criteria). Randomization: Group1 (n?=?40): TRT using 1%-transdermal T-gel (50?mg/day), Group2 (n?=?40) no TRT (controls). Dietary treatment applied to both. Parameters at baseline/after 9?months: anthropometric parameters, lipids and indicators of carbohydrate metabolism (fasting glucose, insulin, HbA1c, HOMA-IR), markers of adipose tissue and EnD (leptin, resistin, p- and e-selectin, ICAM- 1, VCAM- 1 and CRP). ANCOVA for repeated measurements revealed TRT to cause a significant decrease in waist circumference (WC), HOMA-IR and HbA1c vs controls (p?<?.001, p?=?.002, p?=?.004, respectively). Leptin declined in subjects receiving TRT vs controls (p?=?.04). Concentrations of resistin, ICAM-1, p-selectin and CRP decreased significantly vs controls (all p?<?.001); no effects for e-selectin and VCAM-1. Advanced age attenuated effects, higher delta testosterone levels augmented effects. Decrement of WC was related to decreasing markers of adipose tissue secretion/EnD. TRT in men with functional hypogonadism and T2DM improved carbohydrate metabolism and markers of endothelial dysfunction. 相似文献

Objective: This study set out to assess effects of testosterone replacement therapy (TRT) on parameters of metabolic syndrome and vascular function in obese hypogonadal males with type 2 diabetes mellitus (DM2).Study design: Fifty-five obese hypogonadal diabetic males on oral hypoglycemic treatment were enrolled into this one-year, double-blind, randomized, placebo-controlled clinical study. Group T (n?=?28) was treated with testosterone undecanoate (1000?mg i.m. every 10?weeks) while group P (n?=?27) received placebo.Methods: Anthropometrical and vascular measurements – flow-mediated dilatation (FMD) and intima media thickness (IMT) – biochemical and hormonal blood sample analyses were performed at the start of the study and after one year. Derived parameters (BMI, HOMA-IR, calculated free testosterone (cFT) and bioavailable testosterone (BT)) were calculated.Results: TRT resulted in reduction of HOMA-IR by 4.64?±?4.25 (p?.001), HbA1c by 0.94?±?0.88% points (p?.001), and an increase in FMD by 2.40?±?4.16% points (p?=?.005).Conclusion: TRT normalized serum testosterone levels, improved glycemic control and endothelial function while exerting no ill effects on the study population. 相似文献

Background Because of the great controversy over the role of androgens in the pathogenesis of atherosclerosis, we investigated the relationship between serum sex hormone levels and angiographically confirmed coronary artery disease in men.Material and methods We investigated 86 men aged 40–60 years, 56 with coronary artery disease and 30 healthy men, matched by age, as a control group. Body mass index and waist to hip ratio were calculated and total body fat mass and percentage of abdominal deposit were investigated by dual-energy X-ray absorptiometry (Dpx (?+?) Lunar, USA). The serum levels of sex hormones and insulin were measured using commercial radioimmunoassay and IRMA (by SHBG) kits (DPC, USA). The serum levels of lipids and glucose were assessed by means of enzymatic methods.Results Men with coronary artery disease had lower total testosterone levels (17.01?±?6.42 vs. 19.37?±?6.58?nmol/l; p?<?0.05), testosterone/estradiol ratio (228.5?±?88.5 vs. 289.8?±?120.1; p?<?0.05) and free androgen index (FAI) (59.49?±?14.79 vs. 83.03?±?25.81; p?<?0.0001), and higher levels of estrone (49.5?±?27.7 vs. 36.6?±?12.7?pg/ml) than men in the control group. Moreover, men with coronary artery disease were more insulin-resistant than controls and had an atherogenic lipid profile. There was an inverse correlation (p?<?0.05) between testosterone level and serum level of glucose (r?=??0.29), triglycerides (r?=??0.37), body mass index (r?=??0.55), waist (r?=??0.43), total body fat mass (r?=??0.3) and fasting insulin resistance index. A significant positive association (p?<?0.05) was found between testosterone and the quantitative insulin sensitivity check index and high density lipoprotein cholesterol level in serum (r?=?0.26).Conclusions Low levels of total testosterone, testosterone/estradiol ratio and free androgen index and higher levels of estrone in men with coronary artery disease appear together with many features of metabolic syndrome and may be involved in the pathogenesis of coronary atherosclerosis. 相似文献

The accurate measurement of testosterone remains a challenge. The determination of the blood testosterone concentrations in serum by conventional immunoassays is inaccurate in men and even more so in females and children. A new luminescence enzyme immunoassay (LIA) has been developed and validated. The high analytical (8.7 pmol/L) and functional (17.3 pmol/L) sensitivity allows the quantification of the very low concentration in saliva, as well as in serum, after 1/40 dilution. This study measured salivary testosterone levels and compared the results with the free levels calculated from total testosterone and sex hormone-binding globulin in eugonadal and hypogonadal men. Salivary testosterone concentrations in healthy men in morning hours were 369 pmol/L (mean), range 263–544 pmol/L, which was statistically significantly higher than that in men with androgen deficiency, 215 pmol/L (mean), range 51–249 pmol/L.Repetitive determination of free testosterone concentrations in saliva (once a week for 5 weeks) showed high stability of results over time, with coefficient of variation 9% (range 5–23%).In this study we showed that free salivary testosterone levels in morning samples correlated well with calculated free testosterone in blood, both in healthy men (R = 0.754, P = 0.001), and in patients with androgen deficiency (R = 0.889, P = 0.0001), though in cases with very low testosterone, salivary concentrations were systematically higher than calculated free testosterone levels in blood. 相似文献

Objective: The association of caffeine intake with testosterone remains unclear. We evaluated the association of caffeine intake with serum testosterone among American men and determined whether this association varied by race/ethnicity and measurements of adiposity.Methods: Data were analyzed for 2581 men (≥20?years old) who participated in the cycles of the NHANES 1999–2004 and 2011–2012, a cross-sectional study. Testosterone (ng/mL) was measured by immunoassay among men who participated in the morning examination session. We analyzed 24-h dietary recall data to estimate caffeine intake (mg/day). Multivariable weighted linear regression models were conducted.Results: We identified no linear relationship between caffeine intake and testosterone levels in the total population, but there was a non-linear association (pnonlinearity?.01). Similarly, stratified analysis showed nonlinear associations among Mexican-American and Non-Hispanic White men (pnonlinearity?≤?.03 both) and only among men with waist circumference <102?cm and body mass index <25?kg/m2 (pnonlinearity?.01, both).Conclusion: No linear association was identified between levels of caffeine intake and testosterone in US men, but we observed a non-linear association, including among racial/ethnic groups and measurements of adiposity in this cross-sectional study. These associations are warranted to be investigated in larger prospective studies. 相似文献

Objective: Interleukin 18 (IL-18) is an adipokine associated with obesity. Data about the relationship of IL-18 to the metabolic syndrome (MS) are still scarce. Low testosterone (T) levels are common in men with MS, but we did not find data about the levels of IL-18 in men with low T. The aim of this study was to determine the levels of IL-18 in men with MS with or without low T. Patients and methods: A total of 251 men were included in the study. Of them 218 had MS (IDF 2005) and they were divided according to their morning total testosterone (TT) level (cutoff 10.4?nmol/l) into two groups: MS-low T (N?=?84) and MS-normal T (N?=?134). The control group consisted of 33 men without MS and low T. IL-18 was determined in serum using enzyme-linked immunosorbent assay. A small group of eight men with MS and low T levels received testosterone therapy for three months and physical and laboratory parameters were monitored at the end of that period.Results: MS men were at mean age (±SD)?=?53.77?±?9.59 years; body mass index (BMI)?=?34.0?±?6.3?kg/m2; and TT?=?12.59?±?5.66?nmol/l. The control group was at age?=?52.12?±?5.2 years (NS); BMI?=?25.6?±?2.4?kg/m2 (p?.001); and TT?=?17.8?±?5.68?nmol/l (p?.001), respectively. The levels of IL-18 were higher in the MS group – 345?pg/ml compared to the control one – 264?pg/ml (p?.01). There was no significant difference between MS-low T (330.6?pg/ml) and MS-normal T (350.2?pg/ml) subgroups. The MS-normal T differed more significantly from the control group (p?.001). Significant correlation of testosterone with IL-18 levels was not found. IL-18 correlated with parameters of obesity, lipids, fasting blood sugar (p?.05) and the number of criteria for MS (p?.001). Three months on T treatment showed improvement in obesity parameters and only in one patient IL-18 had clear reduction while the rest showed no change.Conclusions: In this study, higher IL-18 levels were found in the presence of MS compared to healthy men, but they did not differ between men having MS with or without LOH. 相似文献

AbstractEstradiol (E2) is, apart from its role as a reproductive hormone, also important for cardiac function and bone maturation in both genders. It has also been shown to play a role in insulin production, energy expenditure and in inducing lipolysis. The aim of the study was to investigate if low circulating testosterone or E2 levels in combination with variants in the estrogen receptor alpha (ESR1) and estrogen receptor beta (ESR2) genes were of importance for the risk of type-2 diabetes. The single nucleotide polymorphisms rs2207396 and rs1256049, in ESR1 and ESR2, respectively, were analysed by allele specific PCR in 172 elderly men from the population-based Tromsø study. The results were adjusted for age. In individuals with low total (≤11?nmol/L) or free testosterone (≤0.18?nmol/L) being carriers of the variant A-allele in ESR1 was associated with 7.3 and 15.9 times, respectively, increased odds ratio of being diagnosed with diabetes mellitus type 2 (p?=?0.025 and p?=?0.018, respectively). Lower concentrations of E2 did not seem to increase the risk of being diagnosed with diabetes. In conclusion, in hypogonadal men, the rs2207396 variant in ESR1 predicts the risk of type 2 diabetes. 相似文献

Purpose.?We performed a randomised controlled study regarding the effects of androgen replacement therapy (ART) on lower urinary tract symptoms (LUTS) in hypogonadal men with benign prostate hypertrophy (BPH).Methods.?Fifty-two patients with hypogonadism and BPH were randomly assigned to receive testosterone (ART group) as 250?mg of testosterone enanthate every 4 weeks or to the untreated control group. We compared International Prostate Symptom Score (IPSS), uroflowmetry data, post-voiding residual volume (PVR) and systemic muscle volume at baseline and 12 months after treatment.Results.?Forty-six patients (ART group, n?=?23; control, n?=?23) were included in the analysis. At the 12-month visit, IPSS showed a significant decrease compared with baseline in the ART group (15.7?±?8.7 vs. 12.5?±?9.5; p?<?0.05). No significant changes were observed in the control group. The ART group also showed improvement in maximum flow rate and voided volume (p?<?0.05), whereas no significant improvements were observed in the controls. PVR showed no significant changes in either group. In addition, the ART group showed significant enhancement of mean muscle volume (p?<?0.05), whereas no significant changes were seen in the controls.Conclusion.?ART improved LUTS in hypogonadal men with mild BPH. 相似文献

Objective.?We examined baseline data from a lipid treatment study to assess the relationship between testosterone (T) and the cardiovascular inflammatory marker, high sensitivity C-reactive protein (hsCRP).Methods.?The baseline T, hsCRP, lipid, glycemic, and anthropometric data were obtained from 467 men (mean age: 52 years). Inclusion criteria included low-density lipoprotein cholesterol ≥?3.4 to 4.9?mmol/l and triglycerides?≤?4.0?mmol/l. The baseline hsCRP levels were examined across the following T subgroups: <6.9?nmol/l (moderate to severe hypogonadism), 6.9 to <10.4?nmol/l (mild to moderate hypogonadism), 10.4 to <15?nmol/l (low-normal T), and?≥?15?nmol/l (normal T).Results.?The median hsCRP levels were significantly (p?=?0.041) different across the four T subgroups; patients in the lower T subgroups had higher median hsCRP levels than patients in the higher T subgroups. The percentage of men with elevated hsCRP (>2?mg/l) was also significantly (p?=?0.038) different across the four T subgroups; 83% of men with T < 6.9?nmol/l had elevated hsCRP compared with 40% with T ≥ 15?nmol/l.Conclusions.?This analysis demonstrated an inverse relationship between serum T and hsCRP in aging men. Urologists need to be aware that low T levels may not only adversely affect sexual function but also may worsen cardiovascular risk in aging, hypogonadal men. 相似文献

The purpose of this study was to evaluate plasma cytokine levels after treatment with saikokaryukotsuboreito (SKRBT), which is a herbal medicine, or androgen replacement treatment (ART), for patients with late-onset hypogonadism (LOH)-related symptoms. Thirty-one patients over 40 years of age with LOH-related symptoms were included in this study. SKRBT was given orally three times daily to a total of 7.5 g/day for 15 eugonadal patients and ART was give to 16 hypogonadal patients by intramuscular injection of testosterone enanthate at 125?mg each time every 2 weeks. Plasma levels of testosterone and 18 cytokines, as well as LOH-related symptoms scored according to the Aging Males' Symptoms (AMS) scale, were compared before and more than 2 months after treatment. In the ART group, the total AMS score was decreased and testosterone was increased significantly after treatment. No cytokine variables were altered significantly after the treatment. In the SKRBT group, although the total AMS score was significantly decreased, testosterone did not change. From the evaluation of cytokines, a significant increase was found in interleukin (IL)- 8, IL-13, interferon-γ and tumour necrosis factor-α. We conclude that SKRBT might improve LOH-related symptoms in eugonadal patients through the beneficial effect of cytokines, a mechanism that is quite different from ART. 相似文献

AbstractObjective: To evaluate the relationship between testosterone levels and the metabolic syndrome (MS) in men older than 45 years.Methods: Six hundred and sixty men (45–70 years) selected from 2906 participants of a population screening for prostate cancer were included in this study. Testosterone and the components of MS were assessed in all men. MS was diagnosed according to NCEP-ATP III criteria. Triglycerides (TG)/HDL-cholesterol (chol) index was calculated.Results: The presence of MS was inversely associated with testosterone (χ2, p?<?0.001), independently of age (OR 0.802, CI 95%: 0.724–0.887, p?<?0.0001). Hypertension was the most frequent abnormality observed followed by elevated TG and waist circumference (WC). Testosterone correlated positively with HDL-chol (r: 0.14, p?<?0.0001) and negatively with body mass index (BMI)(r: ?0.29, p?<?0.0001), WC (r: ?0.26, p?<?0.0001), TG (r: ?0.20, p?<?0.0001), TG/HDL-chol (r: ?0.20, p?<?0.0001), glucose (r: ?0.11, p?=?0.005) and MS score (r: ?0.23, p?<?0.0001).Conclusions: Our results show that in men older than 45 years, as long as testosterone levels decline, the prevalence of MS increases, independently of age. The correlations found between testosterone and four of the five components of MS, as well as with BMI and TG/HDL-chol ratio, a surrogate marker of insulin resistance, suggest considering male hypogonadism as a determinant of developmental abnormalities typical of MS. 相似文献

Introduction: The clinical significance of low to low-normal testosterone (T) levels in men remains debated. Aim: To analyze the effects of raising serum T on lean body mass (LBM), fat mass (FM), total body mass, and health-related quality-of-life (HRQoL). Methods: Randomized, double-blind, placebo-controlled study. Men, aged 50–80 years, with serum total T<15 nmol/L and bioavailable T < 6.68 nmol/L, and a Aging Males’ Symptoms (AMS) total score >36, received 6 months treatment with transdermal 1% T gel (5–7.5?mg/day; n =183) or placebo gel (n =179), followed by 12 months open-label with T in all. Results: After 6 months, LBM increased in T- treated patients by 1.28?±?0.15?kg (mean ± SE) and FM decreased by 1.16?±?0.16?kg, with minor changes with placebo (LBM +0.02?±?0.10?kg and FM ?0.14?±?0.12?kg; all p < 0.001, T group vs. placebo). Changes were largely similar across subgroups of age, baseline total testosterone, and baseline BMI. Total HRQoL improved compared with placebo (p < 0.05, T group vs. placebo). Conclusions: Six months 1% T gel improved body composition and HRQoL in symptomatic men with low to low-normal T, with further improvements over the following 12 months. 相似文献

Objective.?The aim of this study was to evaluate the association between serum levels of testosterone and free testosterone to lifestyle in aging males.Methods.?Men between 45 and 85 years were assessed regarding body mass index (BMI), nicotine and alcohol consumption, stress level, physical and social activity, and sleeping quality by a self-administered questionnaire. In parallel, serum levels of testosterone (T), free testosterone (fT), LH, FSH, DHEA-S, E2 and SHBG were obtained.Results.?In total, 375 men with a mean age of 59.9 years (9.2 ± SD) entered this study; 25.4% and 27.4% had hypogonadal testosterone or free testosterone serum levels, respectively. Nicotine consumption (smokers had higher levels of T and fT; p < 0.01), BMI (negative correlation to T; p < 0.01) and age (negative correlation to fT; p < 0.001) correlated with serum levels of testosterone or free testosterone. Physical and social activity, nicotine and alcohol consumption, stress level and sleep quality did not show a significant association with serum androgen levels.Conclusion.?This prospective study of 375 men aged 45 to 85 years confirms the correlation between age, BMI and smoking with serum levels of testosterone and free testosterone, whereas the investigated variety of lifestyle factors did not show a significant association to serum androgen levels. 相似文献

Background and aim: Vitamin D deficiency and oxidative stress were suggested to be related to prostate cancer risk. We aimed to investigate the association of serum PSA concentration with vitamin D and total oxidant/antioxidant levels.Materials and methods: A total of 95 healthy men were enrolled for the cross sectional study. Serum PSA, 25(OH)D, serum total oxidant status, and total antioxidant status were measured.Results: Serum PSA was significantly negatively correlated with serum total oxidant status (r=??0.309, p?=?.003) but there was no significant correlation between PSA and 25(OH)D (p?=?.383) or total antioxidant levels (p?=?.233). After adjustment for age BMI and smoking status with multiple regression analysis, there was no significant association between serum PSA and total oxidant status.Conclusion: We find no evidence for an association between PSA and vitamin D levels or serum total oxidant/antioxidant levels. 相似文献

Objectives: To assess the association between triglyceride (TG)/high density lipoprotein (HDL) ratio and benign prostate hyperplasia/lower urinary tract symptoms (BPH/LUTS).Methods: Four hundred patients who were admitted to the Urology Clinic between January and December 2014 with complaints of BPH/LUTS were enrolled in this cross-sectional study. Patients were divided into two groups according to their International Prostate Symptom Score and prostate volume (PV). They were compared in terms of age, body mass index (BMI), PV, PSA, post micturional residual volume, uroflowmetry Q max value, fasting blood sugar, TG and high density lipoprotein-cholesterol (HDL-C) level and TG/HDL ratio.Results: Although univariate analyses reveal that age, BMI, waist circumference (WC), FBS, TG, HDL-C level, and TG/HDL ratio were correlated with PV, only age [1.125 OR (1.088–1.164), p?=?.00001], BMI [1.119 OR (1.040–1.204), p?=?.003], TG [(1.043 OR (1.016–1.071), p?=?.002], HDL-C [(0.923 OR (0.860–0.990), p?=?.025], and TG/HDL ratio [(1.224 OR (1.130–1.315), p?=?.014] were statistically significant in multivariate analysis. The calculated area under the curve (AUC) for PV of 30?ml, 40?ml, and 50?ml was 0.668 (0.608–0.727), 0.617 (0.561–0.673), and 0.592 (0.530–0.654), respectively.Conclusions: Our results indicate that the TG/HDL ratio correlates with enhancement in PV. Further studies are warranted to better evaluate this relationship. 相似文献

Background: The prevalence of chronic kidney disease (CKD) in the elderly is high. Serum cystatin C is an accurate marker of kidney function and it also has prognostic utility in CKD patients. The aim of our study was to determine the prediction of serum cystatin C and other markers of kidney function on long-term survival in elderly CKD patients.Methods: Fifty eight adult Caucasian patients, older than 65 years, without known malignancy, thyroid disease and/or not on steroid therapy were enrolled in the study. In each patient, 51CrEDTA clearance, serum creatinine, serum cystatin C, and estimated glomerular filtration rate using different equations were determined on the same day and patients were then followed for 11 years or until their death.Results: The means are as follows: 51CrEDTA clearance 53.3?±?17.4?ml/min/1.73?m2, serum creatinine 1.62?±?0.5?mg/dl, serum cystatin C 1.79?±?0.5?mg/l, Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine equation 40.1?±?14?ml/min/1.73?m2, Berlin Initiative Study 2 (BIS2) equation 38.9?±?10.7?ml/min/1.73?m2, full age spectrum (FAS) creatinine equation 43.8?±?13.8?ml/min/1.73?m2, FAS cystatin C equation 40.1?±?11.7?ml/min/1.73?m2. In the follow up period, 47 (81%) patients died. Cox regression analysis showed different hazard ratios (HRs) for death: for 51CrEDTA clearance HR 1.022 (95% CI 1.004–1.042; p?=?.015), serum creatinine HR 1.013 (95% CI 1.006–1.019; p?=?.001), serum cystatin C HR 2.028 (95% CI 1.267–3.241; p?=?.003), CKD-EPI creatinine equation HR 1.048 (95% CI 1.019–1.076; p?=?.001), BIS2 equation HR 1.055 (95% CI 1.021–1.088; p?=?.001), FAS creatinine equation HR 1.046 (95% CI 1.017–1.074; p?=?.001), FAS cystatin C equation HR 1.039 (95% CI 1.010–1.071; p?=?.009).Conclusions: Our results showed the highest HR for serum cystatin C among kidney function markers for prediction of outcome in elderly CKD patients. 相似文献
