Abstract

The associations of ACE I/D and PAI-1 4G/5G polymorphisms with recurrent pregnancy loss (RPL) in Iranian women have yielded controversial results. Thus, we conducted a meta-analysis to obtain more certain results. A comprehensive literature search was performed in the PubMed, Web of Sciences, Scopus, MedRxiv, SID, and CNKI databases up to January 1st, 2021, using the appropriate terms. All case-control studies were included. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to estimate the strength of associations. A total of 14 studies including eight studies with 783 patients and 761 healthy subjects on ACE I/D and six studies with 1.155 patients and 699 healthy subjects on PAI-1 4G/5G were included. Combined data revealed that ACE I/D polymorphism was significantly associated with RPL risk in Iranian women under three models i.e., allele [OR=0.744, 95% CI: (0.640-0.864); p≤0.001], dominant [OR=0.774, 95% CI: (0.601-0.996); p=0.047], and recessive [OR=0.767, 95% CI: (0.611-0.963); p=0.022]. Moreover, the pooled data showed a significant association between the PAI-1 4G/5G polymorphism and RPL risk under all five models i.e., allele [OR=2.352, 95% CI: (1.623-3.408); p≤0.001], heterozygote [OR=8.364, 95% CI: (4.744-14.756); p≤0.001), homozygote [OR=2.192, 95% CI: (1.093-4.394); p=0.027), dominant [OR=2.354, 95% CI: (1.309-4.235); p=0.004], and recessive [OR=5.208, 95% CI: (3.005-9.025); p≤0.001]. Stratification analysis revealed that these polymorphisms were associated with RPL risk by the number of miscarriages. Our pooled data indicated that ACE I/D and PAI-1 4G/5G polymorphisms were significantly associated with an increased risk of RPL in Iranian women. These significant findings showed that the investigation might be adequate for ACE I/D and PAI-1 4G/5G polymorphisms in the Iranian population.

Özet

İranlı kadınlarda ACE I/D ve PAI-1 4G/5G polimorfizmlerinin tekrarlayan gebelik kaybı (TGK) ile ilişkisi tartışmalı sonuçlar vermiştir. Bu yüzden, daha güvenilir sonuçlar almak için bir meta-analiz gerçekleştirdik. PubMed, Web of Sciences, Scopus, MedRxiv, SID ve CNKI veritabanlarında uygun terimler kullanılarak 01 Ocak 2021 tarihine kadar kapsamlı bir literatür taraması gerçekleştirildi. Tüm olgu kontrol çalışmaları dahil edildi. İlişkilerin gücünü tahmin etmek için olasılık oranları (OO’lar) ve %95 güven aralıkları (GA) kullanıldı. Meta-analize ACE I/D ile ilgili 783 hasta ve 761 sağlıklı denek içeren 8 çalışma ve PAI-1 4G/5G ile ilgili 1.155 hasta ve 699 sağlıklı denek içeren 6 çalışma dahil olmak üzere toplam 14 çalışma dahil edildi. Birleşik veriler, ACE I/D polimorfizminin; allel (OO=0,744, %95 GA: 0,640-0,864, p≤0,001), dominant (OO=0,774, %95 GA: 0,601-0,996, p=0,047) ve resesif (OO=0,767, %95 GA: 0,611-0,963, p=0,022) olmak üzere üç model altında İranlı kadınlarda TGK riski ile önemli ölçüde ilişkili olduğunu ortaya koymuştur. Ayrıca,havuzlanmış veriler, PAI-1 4G/5G polimorfizmi ile TGK riski arasında, beş modelin tümünde, yani allel (OO=2,352, %95 GA: 1,623-3,408, p≤0,001), heterozigot (OO=8,364, %95 GA: 4,744-14,756, p≤0,001), homozigot (OO=2,192, %95 GA: 1,093-4,394, p=0,027), dominant (OO=2,354, %95 GA: 1,309-4,235, p=0,004) ve resesif (OO=5,208, %95 GA: 3,005-9,025, p≤0,001) modellerinde anlamlı ilişkinin varlığını göstermiştir. Tabakalaşma analizi, bu polimorfizmlerin düşük sayısına göre TGK riski ile ilişkili olduğunu ortaya çıkarmıştır. Birleştirilmiş verilerimiz, ACE I/D ve PAI-1 4G/5G polimorfizmlerinin, İranlı kadınlarda artmış TGK riski ile önemli ölçüde ilişkili olduğunu gösterdi. Bu önemli bulgular bizi, İran popülasyonunda ACE I/D ve PAI-1 4G/5G polimorfizmleri açısından araştırmanın yeterli olabileceği kararına götürdü.
