The authors point out a case of intrahepatic cells overload of PAS positive, globules and resistant to amylase digestion in a young Tunisian women of 26 years old with an hepatopathy looking like the one encountered in phenotype Pi Z subjects and a recently appeared total bilateral cataract. The patient and also 4 of the 5 members of her family have a lowered alpha 1 antitrypsin rate serum but the whole family is homozygote phenotype Pi M. The association alpha 1 antitrypsin deficiency bilateral cataract has not been described to our knowledge. The literature review pointing out similar globules in phenotype Pi M subjects and our observation remind us of the possibility of more complicated metabolic trouble of liver, the alpha 1 antitrypsin intrahepatic cells overload of which should be one of its clinical mode of expression.
作者指出,一名26岁的突尼斯年轻女性出现了肝内细胞中PAS阳性、呈小球状且对淀粉酶消化有抗性的情况,她患有类似Pi Z表型患者所患的肝病,且最近出现了双侧完全性白内障。该患者及其家族5名成员中的4人血清α1抗胰蛋白酶水平降低,但整个家族均为Pi M纯合子表型。据我们所知,α1抗胰蛋白酶缺乏与双侧白内障的关联尚未有过描述。文献综述指出Pi M表型患者中存在类似的小球状物质,我们的观察结果提醒我们,可能存在更复杂的肝脏代谢问题,α1抗胰蛋白酶在肝内细胞中的过载可能是其临床表达模式之一。
