In a study of the urinary excretion of haem precursors in patients with rheumatoid arthritis, iron-deficiency anaemia, and in healthy controls, certain differences were found. In iron-deficiency anaemia the excretion of both porphobilinogen and delta-aminolevulinic acid was increased, whereas in patients with rheumatoid arthritis only the porphobilinogen excretion was increased.A further study on the erythrocyte activity of delta-aminolevulinic acid dehydrase showed a higher activity in the erythrocytes from patients with rheumatoid arthritis compared with healthy controls.
在一项关于类风湿性关节炎患者、缺铁性贫血患者及健康对照者血红素前体尿排泄的研究中,发现了某些差异。在缺铁性贫血中,胆色素原和δ-氨基-γ-酮戊酸的排泄均增加,而在类风湿性关节炎患者中,仅胆色素原排泄增加。另一项关于δ-氨基-γ-酮戊酸脱水酶红细胞活性的研究表明,与健康对照者相比,类风湿性关节炎患者红细胞中的该酶活性更高。
