摘要
目的探讨遗传因素在白癜风发病中的作用。方法采用问卷调查形式对815例白癜风患者进行调查,有家族史者与无家族史者两组进行比较,用SPSS10.软件包对资料进行分析。结果①所调查的815例白癜风先证者中,有家族史与无家族史者比例为128:687。②与父母都不发病者比较,父亲患白癜风时子女患白癜风的危险性为132倍;母亲患病时子女患病危险性为72倍。先证者各一级亲属患病相对危险性为12~28倍不等。③父系遗传与母系遗传后代发病年龄及临床表型均无统计学差异。④有家族史和无家族史两组性别和发病年龄均无统计学差异。⑤有家族史者以散发、双侧、进展期居多,与无家族史组比较差异有统计学意义。⑥环境因素中,平均每天日照时间对白癜风遗传者的发病有显著性影响。结论白癜风患者的发病及严重程度与遗传因素有一定关系。
Objective To investigate family history, sex, age of onset, disease severity and environmental predisposing factors in vitiligo patients. Methods Eight hundred and fifteen vitiligo patients were investigated by questionnaires. Patients with family history were compared with those without such history. SPSS 10.0 software package was applied for data analysis. Results Of 815 vitiligo probands, 128 had family history and 687 did not. The heritability rate was 15.7%. Compared with general population, vitiligo probands with affected fathers or mothers had a relative risk (RR) of 132 or 72, respectively. The RRs of those with affected first-degree relatives varied from 12 to 28. There was no significant difference of mean age of onset and disease severity between patients of paternal inheritance and maternal inheritance. No significant difference was found regarding sex and mean age of onset between the groups with and without family history. However, the patients with family history were more likely to have scattered, bilateral distributed and progressive vitiligo. Of the environmental predisposing factors, the mean daily sun-exposure time was closely related to vitiligo in patients with family history. Conclusion Genetic factors may play an important role in the pathogenesis and disease severity of vitiligo.
