A renal transplant recipient presented with bleeding esophageal varices. Needle biopsy, later confirmed by operative wedge biopsy, showed slight periportal fibrosis but no cirrhosis or hepatitis. No etiology for his liver disease could be determined and he could not be differentiated from other reported patients with idiopathic noncirrhotic portal hypertension (IPH). His liver biopsy did show massive hepatic iron deposition. He had received about 115 units of blood while on hemodialysis and had taken oral iron supplementation for 8 years. IPH has been associated with toxin exposure, especially arsenic and vinyl chloride. This case suggests that excessive iron deposition may also lead to IPH and the indiscriminate use of iron supplementation in hemodialysis or renal transplant patients should be avoided.
一名肾移植受者出现食管静脉曲张出血。针吸活检(后经手术楔形活检证实)显示门静脉周围有轻微纤维化,但无肝硬化或肝炎。其肝病病因无法确定,且无法将他与其他报道的特发性非肝硬化门静脉高压症(IPH)患者区分开来。他的肝活检显示有大量肝铁沉积。他在血液透析期间接受了约115单位的血液,并口服铁补充剂8年。IPH与接触毒素有关,尤其是砷和氯乙烯。该病例表明,铁过度沉积也可能导致IPH,应避免在血液透析或肾移植患者中滥用铁补充剂。
