Abstract

INTRODUCTION

We evaluated the association between genetic polymorphisms in exon 1 (A/O alleles) and promoter regions at positions -550 (H/L variant, rs11003125) and -221 (X/Y variant, rs7096206) MBL2 and periportal fibrosis regression.

METHODS

This was a retrospective cohort study involving 114 Brazilians infected with Schistosoma mansoni, who were subjected to follow-up for three years after specific treatment for schistosomiasis to estimate the probability of periportal fibrosis regression.

RESULTS

A risk association was observed between polymorphism at the exon 1 MBL2 and periportal fibrosis regression.

CONCLUSIONS

This study suggests that the polymorphism of exon 1 MBL2 may potentially be used to predict periportal fibrosis regression in this population.

摘要

简介

我们评估了 MBL2 外显子 1（A/O 等位基因）和启动子区域-550（H/L 变体，rs11003125）和-221（X/Y 变体，rs7096206）的遗传多态性与门脉周围纤维化消退之间的关联。

方法

这是一项回顾性队列研究，涉及 114 名感染曼氏血吸虫的巴西人，他们在接受针对血吸虫病的特定治疗后进行了三年的随访，以估计门脉周围纤维化消退的概率。

结果

MBL2 外显子 1 的多态性与门脉周围纤维化消退之间存在风险关联。

结论

本研究提示 MBL2 外显子 1 的多态性可能有助于预测该人群的门脉周围纤维化消退。
