Celiac disease (CD) is a chronic inflammatory intestinal disorder. Different immunological factors, including inflammatory cytokines, may play an important role in disease susceptibility.
To investigate the relationship between -174G/C and -572G/C gene polymorphisms and the serum level of interleukin 6 (IL-6) and susceptibility to CD in the Iranian population.
In this case-control study blood samples were collected of 105 patients with CD and 106 healthy subjects randomly in 2016 and evaluated by polymerase chain reaction-restriction fragments length polymorphism (PCR-RFLP) method. A sequence was also used to confirm the results of both polymorphisms. The IL-6 concentration was measured using ELISA.
The results showed a significant relationship between polymorphism -572G in CD patients when compared with control subjects by genotype ( = 0.001) and alleles ( = 0.022), respectively. There was no significant relationship between polymorphism 174G and frequency of genotype, but an association of this polymorphism with the frequency of alleles ( = 0.034), age ( = 0.001), and body mass index ( = 0.003) was seen. The serum level of interleukin-6 was significantly associated only with rs1800796 ( < 0.001).
The results confirm previous studies in different parts of the world and indicate that IL-6 (572G/C) polymorphism may play a role in susceptibility to CD in the Iranian population.
乳糜泻（CD）是一种慢性炎症性肠道疾病。不同的免疫因素，包括炎性细胞因子，可能在疾病易感性中起重要作用。
研究-174G/C和-572G/C基因多态性与伊朗人群血清白细胞介素6（IL-6）水平及乳糜泻易感性之间的关系。
在这项病例对照研究中，于2016年随机收集了105例乳糜泻患者和106例健康受试者的血样，并采用聚合酶链反应-限制性片段长度多态性（PCR-RFLP）方法进行评估。还使用了一种测序方法来确认两种多态性的结果。采用酶联免疫吸附测定法（ELISA）测量IL-6浓度。
结果显示，与对照组相比，CD患者中-572G多态性在基因型（P = 0.001）和等位基因（P = 0.022）方面均存在显著相关性。174G多态性与基因型频率之间无显著相关性，但该多态性与等位基因频率（P = 0.034）、年龄（P = 0.001）和体重指数（P = 0.003）存在关联。白细胞介素-6的血清水平仅与rs1800796显著相关（P < 0.001）。
结果证实了世界不同地区先前的研究，并表明IL-6（572G/C）多态性可能在伊朗人群乳糜泻易感性中起作用。
