未经治疗的肾功能衰竭通常是以高磷酸盐、低血钙和不同程度的继发性甲状旁腺机能亢进为特征。控制血清磷酸盐可帮助维持钙离子浓度,并调节甲状旁腺素的分泌程度。血清中磷酸盐的控制是靠摄入蛋白质与阳离子铝结合的药物来实现的。目前,一些临床事实表明:组织内铝的蓄积和中毒是由于胃肠道吸收了暴露在普通含有高水平铝元素的透析液中的铝。通常进行性脑病是最大的铝发症而 Untreated renal failure is usually characterized by hyperphosphatemia, hypocalcemia and varying degrees of secondary hyperparathyroidism. Controlling serum phosphate helps maintain calcium levels and regulates parathyroid hormone secretion. Phosphate control in serum relies on the intake of protein and cationic aluminum drugs to achieve. At present, some clinical facts indicate that the accumulation and poisoning of aluminum in tissues is due to the absorption of aluminum in the gastrointestinal tract in dialysate which normally contains high levels of aluminum. Usually progressive encephalopathy is the largest aluminum disease
