The evaluation of renal hemodynamics changes in Familial Mediterranean fever with color Doppler sonography

Background: Renal resistive index (RRI) scanned through renal Doppler is a practical marker employed in measuring blood flow in renal and intrarenal arteries and in noninvasive evaluation of renal vascular resistance. We aimed to investigate the renal hemodynamic variations in patients with Familial Mediterranean Fever (FMF).

Material and methods: Seventy-nine FMF patients and 51 healthy subjects suitable for age and sex were included. Patients were divided into two groups according to their urinary albumin excretion. Fifty-two patients with 0–29?mg/day albuminuria were included in the normoalbuminuric group while 27 patients with 30–299?mg/day albuminuria were included in the microalbuminuric group.

Results: RRI values were higher in patients with FMF compared to the healthy subjects (p?p?=?0.002, p?microalbuminuria in patients was 0.63, sensitivity of 66%, specificity of 60%, and p?=?0.013.

Conclusion: RRI may be a marker that may be used in assessing resistance to renal blood flow, early renal damage, and progression of renal damage in FMF patients.     

Microalbuminuria and the metabolic syndrome and its components in the Chinese population

BACKGROUND: Microalbuminuria and the metabolic syndrome (MetS) have both been linked to chronic kidney disease and cardiovascular disease. This study investigated the association between urinary albumin-to-creatinine ratio (ACR) and MetS and its components. MATERIALS AND METHODS: A total of 2311 subjects aged 40 years and over were recruited in 2004 in a metropolitan city in Taiwan. The biochemical indices, such as fasting glucose levels, urinary albumin, urinary creatinine and anthropometric indices, were measured. We defined microalbuminuria as a urinary ACR ranging from 30 to 300 mg g(-1) creatinine. MetS was defined using the American Heart Association and the National Heart, Lung and Blood Institute (AHA/NHLBI) and the International Diabetes Federation (IDF) definitions. The relationship between MetS and microalbuminuria was examined using multiple logistical regression analysis. RESULTS: Subjects with microalbuminuria had higher age, body mass index (BMI), waist circumference, blood pressure, fasting plasma glucose, triglycerides, total cholesterol (TCHOL)/high-density lipoprotein cholesterol (HDL-C) ratio, prevalence of diabetes mellitus and hypertension and lower HDL-C than subjects with normoalbuminuria. After adjusting for age and BMI, microalbuminuria was associated with the individual components of MetS, except in central obesity in women and elevated fasting glucose in men. After adjusting for age, BMI, smoking and alcohol consumption status, multiple logistical regressions revealed that microalbuminuria is strongly associated with MetS in both genders and according to both definitions. The odds ratio of having MetS using the AHA/NHLBI and IDF definition was 1.76 (1.16-2.67) and 1.73 (1.06-2.83) in men and 2.19 (1.38-3.50) and 2.09 (1.24-3.51) in women, respectively. CONCLUSIONS: Microalbuminuria was strongly associated with MetS and its components. There is an increased likelihood of having MetS if subjects have microalbuminuria.     

杞菊地黄丸联合环丙沙星治疗慢性肾盂肾炎的疗效观察

目的探讨杞菊地黄丸联合环丙沙星治疗慢性肾盂肾炎的临床效果。方法选取日照市妇幼保健院在2015年12月—2016年12月收治的慢性肾盂肾炎患者141例,随机分成对照组(70例)和治疗组(71例)。对照组患者口服盐酸环丙沙星片,1片/1次,3次/d;治疗组在对照组的基础上口服杞菊地黄丸,8丸/次,3次/d。所有患者均经过规律治疗4周。观察两组患者临床疗效,比较治疗前后两组患者主要症状积分、肾功能指标和不良反应情况。结果治疗后,对照组患者临床总有效率为85.71%明显低于治疗组的98.59%,停药半年内对照组和治疗组的重新感染率分别为12.86%、2.82%,两组比较差异具有统计学意义(P0.05)。治疗后,两组主要症状积分明显降低(P0.05);且治疗组积分明显低于对照组(P0.05)。治疗后,两组患者的血清肌酐、血尿素氮和尿微量白蛋白水平均显著降低(P0.05);且治疗组患者肾功能指标水平明显低于对照组(P0.05)。治疗期间,治疗组患者不良反应发生率为4.23%,明显低于对照组患者的17.14%,两组比较差异具有统计学意义(P0.05)。结论杞菊地黄丸联合环丙沙星治疗慢性肾盂肾炎疗效显著,可降低停药半年内重新感染率,具有一定的临床推广应用价值。     

Haptoglobin phenotype and diabetic nephropathy

Abstract Aims/hypothesis. To determine if the haptoglobin 2 allele is associated with an increased risk for the development of diabetic nephropathy. Methods. This study included 110 consecutive normotensive subjects with Type I (insulin-dependent) diabetes mellitus and Type II (non-insulin-dependent) diabetes mellitus seen in two outpatient clinics in Israel. Diabetes duration was greater than 10 years for Type I diabetes and more than 5 years for Type II diabetic subjects. Microalbuminuria was defined as urinary protein excretion of 30 to 300 mg/24 h, and macroalbuminuria was defined as urinary protein excretion of greater than 300 mg/24 h. Serum was taken from subjects for haptoglobin typing by gel electrophoresis. Results. Of the participating subjects 54 had Type I and 56 had Type II diabetes. None (0/18) of the subjects homozygous for the haptoglobin 1 allele (1–1) showed any sign of diabetic nephropathy, as compared with 34 % (19/55) of subjects homozygous for the haptoglobin 2 allele (2–2) and 27 % (10/37) of heterozygous subjects (2–1) (p < 0.04). Of the subjects 29 showed macroalbuminuria. The risk of developing macroalbuminuria was found to be greater in subjects with two haptoglobin 2 alleles (22 %) (12/55) as compared with one haptoglobin 2 allele (8 %) (3/37) or no haptoglobin 2 alleles (0 %) (0/18) (p < 0.03). Conclusion/interpretation. By showing a graded risk relation to the number of haptoglobin 2 alleles in Type I and Type II diabetic subjects, these studies further support our hypothesis that the haptoglobin phenotype is a major susceptibility gene for the development of diabetic nephropathy.

Continuous subcutaneous insulin infusion is more effective than multiple daily insulin injections in preventing albumin excretion rate increase in Type 1 diabetic patients

Aims To compare the effect of continuous subcutaneous insulin infusion (CSII) and multiple daily insulin injections (MDI) on albumin excretion rate (AER) in Type 1 diabetic patients. Methods In a 3‐year multicentre retrospective observational study, 110 Type 1 diabetic patients treated with CSII were compared with 110 patients treated with MDI matched at baseline for age, sex, diabetes duration and HbA_1c. At entry, 90 patients in each group had normal AER and 20 persistent microalbuminuria. AER, estimated glomerular filtration rate (eGFR), HbA_1c, lipids and blood pressure were assessed. Results HbA_1c was lower in the CSII than in the MDI group (8.1 ± 0.9 vs. 8.4 ± 1.3%; P < 0.005 after 3 years). Blood pressure and eGFR were similar during the study. AER [median (95% confidence interval)], similar at baseline [6.0 μg/min (9, 21) in the CSII group vs. 4.4 (8, 16) in the MDI group, NS] was significantly lower in the patients treated with CSII both at year 2 and at year 3 of follow‐up [4.7 μg/min (6, 12) vs. 6.4 (13, 29), P < 0.002]. This difference was observed even when normo‐ and microalbuminuric patients were analysed separately. Nine patients progressed to microalbuminuria in the MDI group and only one in the CSII group. Nine patients regressed to normoalbuminuria in the CSII group, whereas only two regressed to normoalbuminuria in the MDI group. Conclusions Despite a small benefit in terms of improved glycaemic control, CSII therapy may be useful in decreasing the progressive increase in AER in Type 1 diabetic patients.     

社区老年原发性高血压患者尿微量清蛋白与动脉粥样硬化状况分析

目的探讨社区老年原发性高血压患者微量清蛋白尿(MA)与动脉粥样硬化间的关系。方法测定社区112例老年原发性高血压患者(根据血压水平分3组)的MA和颈动脉内膜-中层厚度(IMT)值,并设立健康对照组作对照。结果老年原发性高血压组的尿MA及颈动脉IMT水平均高于健康对照组(P<0.01),并且随着血压升高,MA和IMT有增高趋势;MA水平与颈动脉IMT值呈正相关:r=0.52,P<0.01。结论老年原发性高血压患者MA与动脉粥样硬化相关,MA可作为动脉粥样硬化的预测因子之一。
