摘要
Serum adenosine deaminase (ADA) activity and peripheral lymphocyte subsets of patients with myasthenia gravis (MG) were simultaneously measured. The ADA activity in MG (n = 30) was significantly higher as compared with normal control (n = 150) and multiple sclerosis (n = 12) (P < 0.05). The ADA activity of generalized MG was higher than that of ocular MG, while a significant elevation of ADA activity was observed in grade IIB as compared with grade I of Osserman's classification (P < 0.05). A trend of high ADA activity was demonstrated in those whose disease had advanced to a severe degree associated with unstable clinical features (P < 0.05). In addition, there was a significant elevation of ADA activity in patients who disclosed positive anti-Ach-receptor-antibody as compared with negative one (P < 0.05). There was no specific trend among the proportions of the subsets of peripheral lymphocytes which could reflect the severity of MG, however, the proportion of OK Ia1 + tended to be higher with advancing the grade of MG. Interestingly enough, a close correlation was found between the ADA activity and the proportion of OK Ia1 + cells (P < 0.05). From the above results, it was concluded that high ADA may be responsible for the pathophysiology of MG through the alteration of peripheral lymphocyte function.
