          Abstract

          Background/Aims: IgA nephropathy (IgAN) is a common form of primary glomerulonephritis worldwide. Previous studies indicated that IL-10 single nucleotide polymorphisms (SNP) play an important role in IgAN pathogenesis, but the results were controversy. This study aimed to investigate the association between IL-10 SNPs (rs1800872, rs1800871, and rs1800896) with IgAN in a Chinese Han population. Methods: We conducted a case–control study that included 351 patients with IgAN and 310 age-, gender- and ethnicity-matched healthy controls. Three promoter SNPs (rs1800872, rs1800871, and rs1800896) of IL-10 were genotyped by Sequenom MassARRAY. Odds ratios (ORs) with 95% confidence intervals (CI) were used to assess the relationship with IgAN. Results: We found that the rs1800896 did not correlate with IgAN risk, whereas rs1800872 and rs1800871 were significantly associated with increased IgAN risk in all genetic models. The haplotype analysis indicated that the CCA haplotype was associated with increased IgAN risk (OR = 1.36; 95% CI = 1.05–1.75). Moreover, there were no associations between these SNPs and blood pressure or gender, whereas the rs1800896 variant was correlated with higher 24-hour urine protein in patients with IgAN. Conclusion: Taken together, these results suggest that IL-10 is a susceptibility gene in patients with IgAN.

          High-throughput oncogene mutation profiling in human cancer.

          Systematic efforts are underway to decipher the genetic changes associated with tumor initiation and progression. However, widespread clinical application of this information is hampered by an inability to identify critical genetic events across the spectrum of human tumors with adequate sensitivity and scalability. Here, we have adapted high-throughput genotyping to query 238 known oncogene mutations across 1,000 human tumor samples. This approach established robust mutation distributions spanning 17 cancer types. Of 17 oncogenes analyzed, we found 14 to be mutated at least once, and 298 (30%) samples carried at least one mutation. Moreover, we identified previously unrecognized oncogene mutations in several tumor types and observed an unexpectedly high number of co-occurring mutations. These results offer a new dimension in tumor genetics, where mutations involving multiple cancer genes may be interrogated simultaneously and in 'real time' to guide cancer classification and rational therapeutic intervention.

              Natural history of idiopathic IgA nephropathy: role of clinical and histological prognostic factors.

              G D'Amico (2000)
              Idiopathic immunoglobulin A nephropathy is characterized by an extreme variability in clinical course and sometimes by the unpredictability of the ultimate outcome. Among the numerous studies published in the last 15 years that have calculated the actuarial renal survival and tried to individuate the prognostic role of the clinical and histological features present at the onset of the disease or the time of biopsy, we chose to analyze critically the results of the most valid (30 studies). Actuarial renal survival at 10 years in adults was between 80% and 85% in most of the European and Asian studies, but it was less in studies from the United States and exceeded 90% in the few studies of children. Concordance existed in this selected literature that impairment of renal function, severe proteinuria, and arterial hypertension are the strongest and more reliable clinical predictors of an unfavorable outcome. However, analysis of the prognostic value of morphological lesions was more difficult because they have been characterized in some studies using an overall score or histological classes of progressively more severe involvement and, in others, using a semiquantitative grading of individual glomerular, tubular, interstitial, and vascular changes. In adult patients, a high score of glomerular and tubulointerstitial lesions, corresponding to classes IV and V of the Lee or Haas classifications, predicted a more rapid progression. When single lesions were analyzed separately, glomerulosclerosis and interstitial fibrosis appeared to be the strongest, most reliable predictors of unfavorable prognosis. More controversial was the role of crescents and capsular adhesions. None of the immunohistological features was found to be a risk factor for progression in the more accurate statistical analyses. The same histological features predicted outcome in children, although the severity of lesions at the time of biopsy was usually less than that in adults. However, in the single patient, even the evaluation of these prognostic markers sometimes fails to correctly predict outcome, probably because of the heterogeneity of the disease and the discontinuous activity of some injuring mechanisms during its course.
