[Relation between the level of serum CA19-9 and glucose control in inpatients with diabetes].
OBJECTIVE
To investigate the effect of hemoglobin A1c (HbA1c) and glycated albumin (GA) on serum CA199 in diabetic patients.


METHODS
29 NGT matched control subjects and 371 hospitalized diabetic patients were enrolled. Diabetic patients were divided into satisfactory group (< 6.5%), general group (6.5%-7.5%) and dissatisfactory group (> 7.5%) by the level of HbA1c. The levels of serum CA199 among three groups were compared. The relationship between HbA1c and CA199, GA and CA199 was analysed. Multiple stepwise regression analysis was performed to compare the effect of different variables on CA199 as the independent variables were sex, age, duration, TC, TG, HDL, LDL, FBG, PBG, HbA1c and GA.


RESULTS
(1) CA199 level of the group of HbA1c above 7.5% was significantly higher than the group of HbA1c between 6.5% and 7.5% and the group of HbA1c less than 6.5%. (2) The coefficient of correlation between HbA1c and CA199 was 0.394 (P = 0.000), and that was 0.381 between GA and CA199 (P = 0.000). (3) Multiple stepwise regression analysis show standard regression coefficient of HbA1c is 0.364 (P = 0.000).


CONCLUSIONS
(1) CA199 level of diabetic patient in poor glucose control was significantly higher than the patient in good control. (2) CA199 was positively correlated with FBG, PBG, HbA1c and GA. (3) HbA1c is the independent risk factor of CA199. The elevated CA199 in diabetic patient has close relationship with poor glucose control in a long period.
