The accumulation of extracellular matrix (ECM) is one of the main causes of renal fibrosis. Emerging evidence suggests that the metabolic enzyme of ECM is associated with renal fibrosis. In this study, we applied randomly controlled trial to check the curative effect of Chinese herbs on patients with immunoglobulin A nephropathy (IgAN).
Twenty-six patients were randomly divided into group A (control group) treated with Western Medicine and group B (treatment group) treated with combination of Traditional Chinese Medicine (TCM) and Western Medicine. Blood and urine tests were done before treatment and after 8-week treatment.
The levels of the main composition of extracellular matrix (MC-ECM), the metabolic enzyme of ECM (ME-ECM) and some cytokines in group B decreased more obviously than those in group A after 8-week treatment. So did the level of 24-hour urine protein. However, Metal matrix protease (MMP)-2 and vascular endothelial growth factor in group B increased more obviously than those in group A after 8-week treatment. No effects on the renal function were found in both groups.
Our study provided important information on using the combination of TCM with Western Medicine to inhibit the progression of renal fibrosis in patients with IgAN.

    ABSTRACT: The worldwide medical literature was reviewed to determine whether the prevalence, clinical presentation, and immunohistologic findings of primary IgA nephropathy were related to geographic areas. A total of 68 reports containing detailed clinical histories and laboratory findings were analyzed. The selected articles were grouped according to their geographic origin: Asia, Australia, Europe, and North America (Canada and the United States). Analysis of the data showed that IgA nephropathy is more frequent in the Asian area than in Australia, Europe, and North America. The male/female ratio indicates that males are more likely to be affected by the disease, particularly in the second and third decade of life. The appearance of the disease is characterized by microscopic hematuria and mild proteinuria in Asians, whereas gross hematuria is more frequent in American and European patients. At the time of renal biopsy, fixed microscopic hematuria is detected in a high percentage of patients in Asia and Europe, whereas macroscopic hematuria is more frequent in American patients. Mild renal lesions occur more frequently in Asian patients, while severe renal lesions and a high frequency of immunoglobulin and complement deposits are present in American and European patients. Differences encountered in this retrospective analysis may be influenced by two important factors: (1) the absence of urinalysis screening programs in the schools of Europe and North America, and (2) the different approaches to renal biopsy in the eastern and western parts of the world. Due to the high rate of renal insufficiency and end-stage kidney disease in European and North American patients with IgA nephropathy, it is recommended that a program of urinalysis screening in schools and an appropriate renal biopsy policy be adopted in the western areas of the world.

    ABSTRACT: To analysis the pathological demography in Chinese patients undergoing renal biopsy from our nephrology center. Between January 1979 and October 2000 in Jinling Hospital, Nanjing, China, 10,002 attempts of percutaneous renal were performed in patients with renal disease from 33 provinces of China. The pathological classifications were made according to the WHO criteria of 1982 for renal pathology or the modified WHO criteria of 1995 by a panel of pathologists and nephrologists during routine clinical-pathological rounds. The pathological demography between those specimens collected from 1979 - 1989 and those from 1990 - 1999 was compared. The mean age of the 10,002 subjects undergoing renal biopsy was 31.4 +/- 13.0 years (ranging from 1 to 78 years), with a male to female ratio of 1.3:1; for the 592 renal transplant recipients, the mean age was 37.5 +/- 9.1 years (ranging from 16 to 66 years), with a male to female ratio of 2.36:1. Primary glomerular diseases (PGD) accounted for 71% of the total patients undergoing renal biopsies, secondary glomerular nephritis (SGN) 23%, tubular-interstitial diseases 3.2%, unclassified renal diseases 1.3%, hereditary and congenital renal diseases 1.0%, end stage renal diseases 0.96%, and recently realized or rare renal diseases 0.15%. IgA nephropathy (IgAN) was the most frequent pathological pattern (40%) of PGD, followed by mesangial proliferative lesion (MsPL) (30%), membranous nephropathy (MN) (10%), and focal segmental glomerulosclerosis (FSGS) (6%). Lupus nephritis (LN) was the most pathology common seen (74%) in SGN. During the 22 years of the study period, there was a steady increase in patients with SGN discovered during pathological evaluation of renal disorders. A rise in prevalence was found in IgA nephropathy, MN (both P < 0.001), crescentic glomerulonephritis (P < 0.0001), anti-GBM disease, and hemolytic-uremic syndrome/thrombotic thrombocytopenic purpura related renal damages (both P < 0.001). There was a decrease in endocapillary proliferative glomerulonephritis (P < 0.001) and IgM nephropathy (IgMN) (P < 0.01) from 1990 - 1999 as compared to 1979 - 1989. Infrequent renal pathological entities were also diagnosed in this group, including Niemann Pick disease, Fabry's disease, POEMS syndrome, and lipoprotein glomerulonephropathy. This is the largest series of renal biopsy data in China, and therefore may reflect the demographic picture of renal diseases in this country. Changes in prevalence of renal pathological entities were reflected in this group of patients over the last 22 years. In primary glomerular diseases, IgA nephropathy is still the most frequently observed pathological pattern. In SGN, LN appeared the most often. Increased prevalence was found in anti-GBM nephritis and HUS/TTP.
