ObjectiveTo discuss the relationship between microalbuminuria (MAU) and antioxidant activity of plasma hyper density lipoprotein (HDL) in hypertensive patients, and investigate whether MAU could be a predictor of HDL antioxidant activity. MethodFrom December 2007 to March 2009, sixty consecutive primary hypertensive patients from the inpatient and outpatient departments of West China Hospital and Sichuan Electric Power Central Hospital were included in the study, and 30 healthy volunteers served as controls. MAU, plasma HDL and paraoxonase (PON1) activity were tested. ResultsPON1 activity was lower in hypertensive patients than the controls (P<0.05), and this degree of decline was positively related to MAU (P<0.05). ConclusionMAU reflects PON1 activity in hypertensive patients and can be a predictor to judge plasma HDL function in patients with hypertension.
Objective To formulate an evidence-based treatment plan for a patient with type 2 diabetes and microalbuminuria. Methods According to the patient’s clinical conditions, we put forward 5 clinical problems. We searched the Cochrane Library (Issue 4, 2005), ACP Journal Club (1991 to 2005), and MEDLINE (1991 to 2005) databases. Systematic review, meta-analysis and randomized controlled trials about the treatment of diabetic nephropathy were included. The treatment plan was developed accordingly. Results Thirteen eligible studies were included. Evidence indicated that an intensive intervention aimed at the multiple potential risk factors could be applied to delay or prevent the progression of diabetic nephropathy, which included intensive blood glucose control, tight blood-pressure control, lipid modulation, restriction of protein intake and smoking cessation. The individualized treatment plan was based on the high quality evidence as well as the patient’s specific condition. The patient is still being followed-up. Conclusion Interventions for risk factors of type 2 diabetes like changing living style, decreasing serum glucose, blood pressure, and level of blood fat help to release the clinical symptom and better the long-term living quality of patients.
目的：分析小儿紫癜性肾炎的临床特点。方法：回顾分析两院儿科最近8年收治的小儿紫癜性肾炎180例的临床表现、实验室检查结果，治疗和预后等方面的资料。结果(1)临床以血尿蛋白尿型最多见(61/180)，其次为急性肾炎型(36/180)、肾病综合征型(31/180)和单纯血尿或蛋白尿型(25/180)。(2)重症病儿短期使用激素可改善肾脏损害。(3)所有病例均有必要长期随访。结论：小儿紫癜性肾炎绝大多数预后良好，但病情反复不愈者可发展为终末期肾脏损害，故需要长期随访。
目的：探讨银屑病合并蛋白尿患者的临床特点。方法：回顾性分析1996年1月～2005年8月收治的银屑病合并蛋白尿者临床资料，并与银屑病非蛋白尿者的临床特点比较。结果：银屑病合并不明原因蛋白尿48例，皮肤受累面积与蛋白尿程度无相关关系（P＞0.05），但银屑病合并蛋白尿组的银屑病病程更短,肾脏病理荧光表现为IgA沉积为主。蛋白尿组皮肤受累面积与非蛋白尿组皮肤受累面积比较，无统计学意义（P＞0.05），蛋白尿组和非蛋白尿组的病程也无统计学差异（P＞0.05）。结论：银屑病合并不明原因蛋白尿值得重视，有必要对其发病机制、临床特点、病理特征进行深入的研究。
Objective To make individualized evidence-based treatment for patients with diabetic nephropathy with albuminuria. Methods Based on the clinical questions we raised, evidence was collected and critically assessed. Patients’ willingness was also taken into consideration in the decision-making treatment Results Seventy studies were retrieved and finally 14 randomized controlled trials, 2 systematic reviews, 2 meta-analyses and 41 clinical guidelines were considered eligible. The evidence indicated that albuminuria was an independent cardiovascular risk factor of diabetic patients; angiotensin receptor antagonists might decrease the level of urinary albumin excretion in patients with type 2 diabetic nephropathy; and such patients might benefit from blood glucose and blood pressure control. The individualized treatment plans were developed based on the available evidence. After 1 month of treatment, the serum creatinine returned to normal and albuminuria became negative. Conclusion The individualized treatment plans based on the high quality evidence were optimal in reducing cardiovascular complications and urinary albumin excretion. However, long-term prognostic benefits need to be confirmed by further follow-up.
ObjectiveTo observe whether proteinuria is relate to the decline of residual renal function (RRF) in peritoneal dialysis (PD) patients. MethodsThis is a prospective cohort study including 45 PD patients (underwent PD between January 2011 and January 2013) with a 12-month follow-up. All the patients were divided into 2 groups with respect to the initial proteinuria level: massive proteinuria group A (n=20) and non-massive proteinuria group B (n=25) at baseline. We established regression models to do univariate analysis and multivariate analysis of the relationship between the decline of RRF≥50% of baseline and the indices of age, sex, PD-associated peritonitis, baseliner residual glomerular filtration rate (rGFR), initial proteinuria, and use of ACEI/ARB. ResultsThe primary outcome (RRF>50% of baseline) at 12 months was 65% in group A, and 80% in group B (P<0.05). Based both on the results of univariate and multivariate Cox regression analysis, non-massive proteinuria and higher rGFR at baseline were factors to protect RRF from decline (P<0.05). ConclusionThe study demonstrates that massive proteinuria and lower rGFR at baseline may be associated with a rapid decline of RRF in PD patients. Treatment aimed at reducing albuminuria may lead to protect RRF and improve life quality of patients.
