title: Angiotensin-converting enzyme gene polymorphism is correlated to the progression of disease in patients with IgA nephropathy: a meta-analysis.
abstract: Angiotensin-converting enzyme (ACE) displays potent vasoconstrictive effects, attenuation of fibrinolysis, and platelet activation and aggregation. Recently it was mentioned that the insertion/deletion polymorphism of the ACE gene is associated with ESRD. The lengthy course of IgA Nephropathy (IgAN) and the possibility of good outcomes without therapy suggest nontoxic therapies such as ACE inhibitors and angiotensin receptor blockers (ARBs). However, the correlation between the ACE gene polymorphism and progression of IgAN still requires further approval. Here, the author performs a summative analysis on the recent previous reports on the ACE gene polymorphism and its correlation to progression of IgAN. The meta-analysis was performed to assess the correlation between the pattern of ACE gene polymorphism and progression of IgAN. From five available studies, 346 and 555 patients with (group 1) and without (group 2) the progression of disease are evaluated. According to this study, the frequency of DD genotype in group 1 is significant higher than group 2 (p < 0.05). In addition, the author first reports a non-significant correlation between the ethnicity and the ACE gene polymorphism.
