Research progress of vimentin in lupus nephritis

Systemic lupus erythematosus is an autoimmune disease involving multiple organs of the body. Lupus nephritis is one of the most serious organ manifestations of systemic lupus erythematosus. Vimentin, a member of the intermediate filament protein family, is involved in the pathogenesis of many autoimmune diseases, including lupus nephritis. More and more studies have shown that vimentin plays an important role in the pathogenesis of lupus nephritis, and has an important influence on the disease development, treatment and prognosis of lupus nephritis. This review focuses on the structure, function and post-translational modification of vimentin, the relationship between vimentin and the pathogenesis of lupus nephritis, and the significance of vimentin expression levels in renal tissues, serum and urine, in order to provide theoretical basis for future mechanism research and clinical application.

小管间质性肾炎-葡萄膜炎综合征

小管间质性肾炎-葡萄膜炎综合征是一种新发现的疾病，多发生于青少年女性。其全身表现主要有乏力、体重减轻、发热、恶心呕吐、腹痛或腰痛，眼部一般表现为双眼非肉芽肿性前葡萄膜炎，葡萄膜炎和间质性肾炎发生的时间间隔一般在１年内。实验室检查发现贫血、红细胞沉降率增高、肾功能不全、尿beta;2-微球蛋白升高，肾活检显示肾间质炎症细胞浸润。细胞免疫可能在其发病中起重要作用。治疗以局部和全身应用糖皮质激素为主，预后较好，肾炎一般不复发，而葡萄膜炎易复发。 (中华眼底病杂志, 2002, 18: 325-326)

Mycophenolate Mofetil for Proliferative Lupus Nephritis: A Systematic Review

Objective　To assess the effectiveness and safety of mycophenolate mofetil (MMF) in the treatment of proliferative lupus nephritis. Methods　We searched CBM (November 1979 to February 2006), Chinese Cochrane Centre Database (2005), The Cochrane Library (Issue 4, 2005), MEDLINE (November 1966 to February 2006) and EMBASE (1975 to February 2006) for randomize controlled trials. Data were extracted and analyzed using The Cochrane Collaboration’s RevMan 4.2.7. Results　Nine randomize controlled trials involving 512 patients met the inclusion criteria. The meta-analysis showed that the total clinical effective rate and complete remission rate were not significantly higher for MMF than for cyclophosphamide, azathioprine, or both. Renal survival rate and relapse rate of MMF were not significantly different from those for cyclophosphamide, azathioprine, or both. Patient survival rate and safety of MMF were significantly improved compared with cyclophosphamide, azathioprine, or both. Conclusion　More large-scale multi-center randomized trials are needed to investigate the role of MMF in the treatment of proliferative lupus nephritis.

Research progress on immunoglobulin A nephropathy with positive anti-neutrophil cytoplasmic antibody

In recent years, with the improvement and popularization of anti-neutrophil cytoplasmic antibody (ANCA) detection technology, more and more patients with immunoglobulin A nephropathy (IgAN) have been tested positive for serum ANCA. The clinical value of ANCA is still unclear, and there is a lack of consensus on diagnosis and treatment strategies. This article reviews the clinical and pathological characteristics, diagnosis, and treatment features of IgAN patients with serum ANCA positivity through literature reading and analysis, aiming to provide a reference for standardized diagnosis and individualized management of this type of patient.

Efficacy and Safety of Mycophenolate Mofetil for Henoch-Schonlein Purpura Nephritis: A Systematic Review

ObjectiveTo systematically review the efficacy and safety of mycophenolate mofetil (MMF) for Henoch-Schonlein purpura nephritis (HSPN). MethodsDatabases such as PubMed, EMbase, CENTRAL, VIP, CNKI, CBM and WanFang Data were electronically searched for comprehensively collecting the randomized controlled trials (RCTs) on the efficacy and safety of MMF for HSPN from inception to December, 2013. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the methodological quality of the included studies. Then meta-analysis was performed using RevMan 5.1 software. ResultsA total of 10 RCTs involving 426 patients (231 in the trial group and 195 in the control group) were included. The trial group was treated with MMF and corticosteroids, and the control group was treated with corticosteroids monotherapy or combined with cyclophosphamide (CTX), leflunomide (LEF), or azathioprine (AZA). The results of meta-analysis showed that, as for efficacy, no significant difference was found between the two groups after six-mouth treatment (OR=1.36, 95%CI 0.67 to 2.73, P=0.85), while after twelve-mouth treatment, MMF was superior to CTX with a significant difference (OR=6.58, 95%CI 2.45 to 17.33, P=0.002). In addition, the efficacy of MMF was still superior to the azathioprine group, but not better than either LEF or prednisone monotherapy. Lower incidence of side effects were found in the MMF group, compared with the CTX group (OR=0.25, 95%CI 0.13 to 0.45, P < 0.000 01) and the prednisone monotherapy group (OR=0.26, 95%CI, 0.09 to 0.79, P=0.02), while there was no significant difference between the MMF group and the LEF group in side effects. ConclusionBased on the current evidence, the efficacy of MMF for HSPN is better than CTX, and its side effects are less than those of CTX and prednisone.

Characteristics and diagnostic value of temporal retinal thinning in young patients with Alport syndrome

ObjectiveTo observe the features of temporal macular thinning and its value for the diagnosis of Alport syndrome (AS) in young patients.MethodsEighty-one young patients with AS (81 eyes) from Peking University First Hospital during January 2016 and July 2017 were included in this study. There were 67 males (67 eyes) and 14 females (14 eyes),the aged from 3 to 17 years, with the mean age of 9.6 years. Among 81 patients (81 eyes), there were 64 patients with X-linked AS (XLAS, including 53 males and 11 females), 17 patients with autosomal recessive AS (ARAS, including 14 males and 3 females). One hundred healthy subjects aged 4 to 17 years were included as controls. Clinical data were retrospectively evaluated, including visual acuity, slit-lamp microscopy, dilated fundus photography, and OCT. Retinal thickness was measured with an OCT scan and the temporal thinning index (TTI) was calculated as stated in a previous study. The TTI values of each group was compared by One-way ANOVA or independent sample t test. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic effectiveness for AS.ResultsThe TTI of the control group, XLAS and ARAS patients were 6.46±1.58, 10.93±3.77, 12.14±4.05, respectively. Compared with the control group, the TTI value of males were larger in the XLAS and ARAS group (F=45.056, P＜0.001), the TTI value of females were larger in the ARAS group (F=26.541, P＜0.001). The difference of TTI value in females was significant between the XLAS and ARAS groups (F=26.541, P＜0.001). In males, the area under the ROC curve was 0.896 (95%CI 0.837−0.955, P＜0.001). The optimal cutoff value of the TTI was determined as 9.47, with a sensitivity of 73.1% and a specificity of 100%.ConclusionsTTI is a common ocular finding in young patients with AS. In males, a TTI ＞ 9.47 may differentiate AS from normal males.
