巴西村庄多人患“吸血鬼病” 阳光照射患皮肤癌

2015-08-20 10:49:42   中国新闻网

据香港《东方日报》8月20日报道,巴西南部一个住有约800人的农村,有三分之二的居民受罕见的遗传皮肤病基因影响,对紫外光非常敏感,易于患上皮肤癌。医生由于暂时没有治疗方案,故建议他们要完全与阳光隔绝,还指出患病机率如此高,与村民通婚有关。

据报道,该村位于距离圣保罗约110公里的阿拉拉斯市,村民体内有名为着色性干皮症(XerodermaPigmentosum,简称XP)的基因,患者的皮肤未能抵挡紫外线,容易被晒伤,且不能自行修复,因此极易患上皮肤癌,病况更会迅速恶化。由于患者不能照射阳光,只能在晚上出外,该病又被称为“吸血鬼病”。

目前,村内还有20人确诊患上XP,患者的皮肤一旦受损就会溃烂,外表看起来相当吓人。其中确诊村民、38岁的雅尔丁(DjalmaJardin)早前接受纪录片访问,透露自9岁起,脸部长出大量雀斑及肿块,并因此病而毁容,只剩下一只眼睛完好,但因眼睑受损,致睡觉时不能闭上眼睛。他在受访后不久病情恶化,不幸身故。还有患者因病发要切除右侧下颚骨,须依赖“假体”才可说话。

XP须父母同时拥有导致这病的基因,诞下的子女方会患上此症。专家估计,该农村最初有数个家庭,XP的基因分别存在不同成员身上,他们其后集中与村内人通婚,故农村患XP的比率高于寻常。村民本来是务农维生,但专家警告,XP病人不能被阳光照射,即使只是数分钟,也会令癌细胞扩散,加上现时没有治疗方法,令失去生计的患者感绝望。
