Abstract
Objective:
Meta-analysis was performed in the current study to evaluate the relationship
of the angiotensin-converting enzyme insertion/deletion polymorphism with
the risk of the incidence of Henoch–Schönlein purpura.
Methods:
The electronic databases, including Embase, PubMed and Google scholar, were
systemically retrieved to search for related articles. Meanwhile,
statistical analysis was performed using the odds ratio and the
corresponding 95% confidence interval.
Results:
A total of six articles enrolling 504 patients and 706 healthy controls was
enrolled into the current meta-analysis. Results of the meta-analysis
suggested that the angiotensin-converting enzyme D allele was markedly
correlated with the risk of the incidence of Henoch–Schönlein purpura among
the general population (deletion (D) vs. insertion (I): odds ratio (OR)
1.42, 95% confidence interval (CI) 1.05–1.93; DD vs. II: OR 2.23, 95% CI
1.06–4.70; DI vs. II: OR 1.36, 95% CI 1.00–1.85; dominant model: OR 1.56,
95% CI 1.00–2.42; recessive model: OR 1.83, 95% CI 1.06–3.16). Moreover,
such a polymorphism was found to correlate with the susceptibility to
Henoch–Schönlein purpura when studies were stratified according to the
sample size of over 200. In addition, such a polymorphism was recognised to
be remarkably associated with the susceptibility to Henoch–Schönlein purpura
in the Caucasian population, which was not found in the Asian
population.
Conclusions:
The results of the current meta-analysis indicate that the
angiotensin-converting enzyme D allele might be a risk factor against the
risk of Henoch–Schönlein purpura, especially in Caucasians.
