Some studies have assessed the association between angiotensin-converting enzyme (ACE) I/D polymorphism and acute respiratory distress syndrome (ARDS) risk. However, the results have been inconclusive and contradictory. Therefore, we performed a meta-analysis to investigate the association between ACE I/D polymorphism and ARDS risk.
All relevant studies were searched using PubMed and EMBASE. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were estimated using random-effects models or fixed-effects models.
A total of 14 studies with 5218 subjects were included in this meta-analysis. We found that ACE I/D polymorphism significantly associated with an increased ARDS risk (OR=1.57; 95% CI 1.30-1.89; P<0.00001). In the subgroup analysis by race, Caucasians with ACE I/D polymorphism showed increased ARDS risk (OR=1.63; 95% CI 1.32-2.02; P<0.00001). However, Asians with this polymorphism did not show significantly increased ARDS risk (OR=1.31; 95% CI 0.90-1.90; P=0.95). In the subgroup analysis by age group, adults showed increased ARDS risk (OR=1.60; 95% CI 1.32-1.93; P<0.00001), while pediatric patients did not have increased ARDS risk (OR=1.15; 95% CI 0.57-2.30; P=0.70).
This meta-analysis suggested that ACE I/D polymorphism might contribute to the susceptibility for ARDS.
一些研究评估了血管紧张素转换酶（ACE）I/D多态性与急性呼吸窘迫综合征（ARDS）风险之间的关联。然而，结果尚无定论且相互矛盾。因此，我们进行了一项荟萃分析以研究ACE I/D多态性与ARDS风险之间的关联。
使用PubMed和EMBASE检索所有相关研究。采用随机效应模型或固定效应模型估计比值比（OR）及相应的95%置信区间（CI）。
本荟萃分析共纳入14项研究，涉及5218名受试者。我们发现ACE I/D多态性与ARDS风险增加显著相关（OR=1.57；95%CI 1.30-1.89；P<0.00001）。在按种族进行的亚组分析中，具有ACE I/D多态性的白种人ARDS风险增加（OR=1.63；95%CI 1.32-2.02；P<0.00001）。然而，具有这种多态性的亚洲人ARDS风险并未显著增加（OR=1.31；95%CI 0.90-1.90；P=0.95）。在按年龄组进行的亚组分析中，成年人ARDS风险增加（OR=1.60；95%CI 1.32-1.93；P<0.00001），而儿科患者ARDS风险未增加（OR=1.15；95%CI 0.57-2.30；P=0.70）。
这项荟萃分析表明，ACE I/D多态性可能与ARDS易感性有关。
