目的:研究分别用肌酐和渗透压校正随机尿、晨尿中的常规生化指标与24 h尿中对应指标含量的相关性。方法:收集患者同一天内的24 h尿、晨尿和随机尿,分别测定三种不同类型尿液中的蛋白、电解质(钾、钠、氯)、和尿酸UA的含量,其中晨尿和随机尿的结果分别以肌酐比值和渗透压比值表示,用SPSS11.5软件进行数据处理和秩相关分析。结果:随机尿、晨尿尿蛋白/尿肌酐比值和尿蛋白/尿渗透压比值与24 h尿蛋白定量结果相关性良好(P<0.05),相关系数约为0.8;随机尿、晨尿尿电解质/尿肌酐比值和尿电解质/尿渗透压比值与24 h尿电解质的相关性较差;随机尿、晨尿尿酸校正后没有相关性。结论:晨尿和随机尿尿蛋白/尿肌酐比值代替24 h尿蛋白的测定有标本收集方便易行的优势;用肌酐校正随机尿、晨尿尿电解质的临床评价有待进一步的研究;尿酸的测定仍须采用24 h尿标本。而晨尿、随机尿用渗透压做校正效果与肌酐校正一致。  相似文献

BACKGROUND: The protein:creatinine ratio in random, untimed urine samples correlates with 24-h protein excretion in pregnant women with and without hypertension. Nevertheless, whether this ratio is appropriate as a screening test for proteinuria is still unclear, in part because of the paucity of large studies. METHODS: We measured protein:creatinine ratios in random urine samples and protein contents of 24-h urine samples in a cross-sectional study of 927 hospitalized pregnant women at >/=20-weeks of gestational age and in a 2nd cohort of 161 pregnant women. In the 2nd group, urine specimens were obtained before and after completion of the 24-h collections, avoiding 1st-morning void specimens. RESULTS: Protein excretion was >/=300 mg/24 h in 282 patients (30.4%). The urine protein:creatinine ratio and the 24-h protein excretion were significantly correlated (r = 0.98, P <0.001). The protein:creatinine ratio as an indicator of protein excretion >/=300 mg/24 h was >/=0.3. The sensitivity and specificity were 98.2% and 98.8%, respectively. Positive and negative predictive values were 97.2% and 99.2%, respectively, and positive and negative likelihood ratios were 79.2 and 0.02, respectively. The diagnostic accuracy of the urinary protein:creatinine ratio was corroborated in the 2nd cohort of patients, which also showed no statistically significant difference in protein:creatinine ratio between samples obtained >24 h apart. CONCLUSIONS: Random urinary protein:creatinine ratio is a reliable indicator of significant proteinuria (>300 mg/day) in nonambulatory pregnant women, irrespective of sampling time during the daytime. The protein:creatinine ratio may be reasonably used as an alternative to the 24-h urine collection method.  相似文献

Abstract:
Objective To evaluate the spot urine sample collection method and value of urinary albumin measurement in population survey. Methods Six hundred and fifty-nine Beijing residents were requested to collect 24 h urine for detection of UAER, as well as random spot urine samples and morning urine samples in the next day. Rapid semi-quantitative urinary albumin-specific dipstick and ACR were measured in each spot urine specimen. The 24 h UAER was measured as golden standard to generate ROC curves and evaluate the sensitivity, specificity and AUC of each method. Results The value of ACR in the morning spot urine samples and random spot urine samples were 9. 36(5. 12-33.29) mg/g and 11.29(6. 34-41.29) mg/g respectively and there was no significant difference between these two groups (t = - 1. 382,P>0.05). The correlation was significant in the two groups (r = 0.932, P < 0.01). The correlation coefficient between ACR in the morning spot urine samples and UAER was 0. 853 (P < 0. 01). The correlation coefficient between ACR in the random spot urine samples and UAER was 0. 874 (P <0. 01).The sensitivity and specificity of ACR for diagnosis of albuminuria in the random urine samples were 77. 9% and 91.0%. The sensitivity and specificity of ACR for diagnosis of albuminuria in the morning urine samples were 78. 4% and 95.7%. Concerning the semi-quantitative urinary albumin-specific dipstick, sensitivity and specificity were 90. 3% and 41.1% , respectively. The specificity was much lower than that of ACR. The area under the ROC curves of ACR in the random urine specimens and the morning urine specimens was 0. 918 ±0. 012, 0. 929 ± 0. 015, respectively. There was no statistical difference between these two groups (χ2 =2. 13, P>0. 05). The area under the ROC curves of semi-quantitative urinary albumin-specific dipstick in the random urine specimens was 0.661 ±0.021, lower than that of ACR (χ2 = 248.41, P<0.01).Conclusion Measurement of ACR in random urine samples is a reasonable method with simplicity and accuracy for the detection of albuminuria in general population screening program.  相似文献

Total protein, albumin, alpha1-microglobulin, and immunoglobulin G (IgG) were analyzed in 1,622 urine samples without Bence-Jones proteinuria or gross hematuria. There was correlation with the histological picture obtained on renal biopsy in 61 patients. We established 24-h reference intervals for alpha1-microglobulin and IgG on 659 urine samples with total protein and albumin excretion rates below 100 mg/24 h and 30 mg/24 h, respectively, and creatinine clearance above 80 ml/min. The central 95% reference interval was found to be between 4 and 17 mg/24 h for alpha1-microglobulin and between 3 and 8.5 mg/24 h for IgG. In 80 urine samples with albumin excretion rate above 30 mg/24 h and alpha1-microglobulin and IgG within their reference intervals, we analyzed the 95% central interval of the distribution of the IgG/albumin ratios, and it was found to be within 0.01 and 0.20 (0.90 confidence interval: 0.17-0.24). Proteinuria was considered to be of the selective glomerular type if the albumin excretion rate was abnormal and the IgG/albumin ratio was under 0.20, even when the IgG excretion was within a pathological range. For the classification of proteinuria as predominantly tubular, we estimated the alpha1-microglobulin/albumin ratio in 173 urine samples with normal excretion rates of albumin and IgG and pathological excretion of alpha1-microglobulin. The discriminating value of 0.91 (0.90 confidence interval: 0.78-1.08) was accepted in order to define proteinuria of a tubular origin in the presence of a pathological albumin excretion rate. The association between albumin and IgG excretion rates and tubular reabsorption of the alpha1-microglobulin normally filtered by the glomerulus was studied in 33 urine samples from patients with no histologically significant tubulo-interstitial or vascular disease and a serum creatinine concentration below 141 pmol/l. The optimal curve-fitting function between albumin plus IgG and alpha1-microglobulin excretion rates was of the quadratic type (r = 0.927). Mixed proteinuria was considered when both, albumin and alpha1-microglobulin excretion rates were pathological and could not be included in the previously described groups.  相似文献

BACKGROUND: Normal individuals usually excrete very small amounts of protein in the urine. Persistently increased protein excretion is usually a marker of kidney damage. Quantifying protein in urine is commonly used in the diagnosis of kidney diseases, detection of treatment effects and evaluation of prognosis. We evaluated the use of the total protein-to-creatinine ratio (P/C) in spot urine specimens as a predictor of urine protein excretion in 24-h collections. METHODS: The correlation between P/C in first morning and random urine specimens and urinary protein excretion in 24-h collections were analyzed. The cutoff value of P/C in first morning urine specimens for screening urinary protein excretion of 1 and 3 g in 24-h collections was determined by receiver operating characteristics (ROC) curve. RESULTS: For patients with Ccr 10 ml/min, the correlation was highly significant. Similar results were obtained for random urine specimens. By ROC curve analysis, the P/C of 0.94 and 2.84 g/gcr in first morning urine specimens represent the best threshold to detect urine protein excretion of 1 and 3 g in 24-h collections, respectively. There is a good correlation between P/C in first morning urine specimens and random urine specimens from inpatients and outpatients. But the P/C in random specimens is significantly higher than that in first morning specimens in outpatients. CONCLUSION: The P/C in spot urine samples could be used as an alternative to urine protein excretion in 24-h collections in patients with Ccr>10 ml/min. The P/C in first morning urine samples is better than that in random specimens, especially for outpatients.  相似文献
