目的 探讨不同性别IgA肾病患者合并高尿酸血症的临床及肾脏病理特点。 方法 采用回顾性研究方法，将2008年1月－2010年12月收治的226例经肾活检确诊的原发性IgA肾病患者分为男性高尿酸血症组、男性尿酸正常组、女性高尿酸血症组及女性尿酸正常组4组，统计分析4组的临床指标及病理指标。 结果 高尿酸血症患病率男性（21.7%）高于女性（11.9%），差异有统计学意义（P＜0.01），尿检异常型患病率男性（14.6%）高于女性（4.0%），差异有统计学意义（P＜0.01），女性LeeⅢ级的患病率（7.1%）高于男性（5.8%），差异有统计学意义（P＜0.01）；男性高尿酸血症组的尿素氮高于尿酸正常组（P＜0.05），女性高尿酸血症组的血尿素氮、血肌酐、胱抑素C、舒张压、甘油三酯比尿酸正常者明显增高（P＜0.01），女性高尿酸血症组的高密度脂蛋白明显高于男性组（P ＜0.01）。 结论 高尿酸血症是IgA肾病的危险因素，可导致更严重的肾功能损害及肾脏病理损害，这种影响在不同性别中存在差异。
Objective To systematically review the efficacy of total glycosides extracted from Rehmannia glutinosa Libosch leaf in the treatment of diabetic nephropathy. Methods Databases including PubMed, EMbase, MEDLINE, The Cochrane Library, Web of Science, CNKI, WanFang Data and VIP were electronically searched to collect randomized controlled trials of total glycosides from Rehmannia glutinosa Libosch for diabetic nephropathy from inception to May 30th, 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. RevMan 5.4 software was then used to perform meta-analysis. Results A total of 7 RCTs involving 504 patients were included. The results of meta-analysis showed that there were no significant differences in creatinine levels (MD=−1.71, 95%CI −3.97 to 0.56, P=0.14) and urea (MD=−0.18, 95%CI −0.44 to 0.08, P=0.19) between the two groups. In terms of regulating proteinuria, the urinary albumin excretion rate (MD=−39.41, 95%CI −48.46 to −30.36, P<0.000 01), urinary microalbumin (MD＝−9.94, 95%CI −12.16 to −7.73, P<0.000 01), and 24-hour urinary protein (MD=−0.67, 95%CI −0.85 to −0.49, P<0.000 01) were all lower in the treatment group compared with control group. However, there were no differences between groups in terms of blood glucose metabolism as indicated by changes in levels of the long-term blood glucose metabolism indicator (HbA1c: MD=−0.16, 95%CI −0.67 to 0.35, P=0.53). Only one study suggested that short-term blood glucose metabolism indicators, fasting blood glucose and postprandial blood glucose levels were not different between groups. In terms of blood lipid metabolism, only one study suggested glycoside treatment produced lower serum levels of cholesterol and triglycerides compared with control group. Conclusions Current evidence suggests that adjunctive therapy with total Rehmannia glutinosa Libosch glycosides can benefit diabetic nephropathy patients more than angiotensin II receptor inhibitor or pancreatic kininogen by alleviating proteinuria and likely improving lipid metabolism. However, no benefit is observed in terms of renal function improvement or blood glucose metabolism. Due to limited quality and quantity of included studies, more high-quality studies are required to verify the above conclusions.
Objective To assess the efficacy and safety of okra capsule for IgA nephropathy. Methods All randomized or quasi-randomized controlled trials (RCTs or quasi-RCTs) of okra capsule for IgA nephropathy were collected from CENTRAL, MEDLINE, EMbase, PubMed, WanFang Data, CNKI and CBM. Two reviewers independently screened the included studies, extracted the data, assessed the quality, and cross-checked then. Then RevMan 5.07 software was used for meta-analysis. Results Five RCTs were included. The results of meta-analyses showed that: compared with the control group, okra capsule was more effective in decreasing urinary protein (P≥0.05), but had no significant difference in improving renal function, reducing urine red blood cells and blood lipid (Plt;0.05). No research reported the adverse effects of okra capsule. Conclusion Current evidence reveals that okra capsule can reduce urinary protein and improving therapeutic effect for IgA nephropathy. However, further studies are needed to test its safety. Because of the small sample size and low methodological quality of the included studies, these results require more high-quality RCTs for further verification.
目的 探讨抗核抗体（ANA）在IgA肾病中的阳性率及其对临床的意义。 方法 回顾性分析2007年1月－2009年12月间进行ANA检测的115例IgA肾病患者及59例非IgA肾病慢性肾炎患者的临床资料。统计分析ANA阳性与阴性的临床指标。 结果 IgA肾病患者中有12例（10.4%）存在ANA阳性，与非IgA肾病慢性肾炎中的阳性率比较差异无统计学意义（P＞0.05），ANA阳性的IgA肾病血浆IgG水平较高，病理改变较轻。 结论 IgA肾病ANA阳性的机体免疫有增强，肾功、尿蛋白及病理损害较轻，其对IgA肾病预后的影响仍需进一步研究。
