OBJECTIVE: To explore the diagnostic value of protein induced by vitamin K absence or antagonist -II(PIVKA-II) in non-infant with acquired deficiency of vitamin K-dependent coagulation factors(ADVKCF).
METHODS: PIVKA-II levels were measured by ELISA in 50 patients with ADVKCF on day 0, 3, 7 after vitamin K treatment. Prothrombin time(PT), APTT, FII: C, FVII: C, FIX: C, and FX: C were analyzed simultaneously. Twenty healthy subjects were enrolled as controls.
RESULTS: The average level of PIVKA-II in ADVKCF group was (3.83 ± 1.40)µg/L, while (1.30 ± 0.54) µg/L in the control group (P < 0.05). The PIVKA-II levels on day 0 and 3 did not show significant difference [(3.83 ± 1.40) µg/L vs (3.79 ± 0.66) µg/L, P > 0.05], but decreasing significantly on day 7 compared to the control group(P < 0.05). The PIVKA-II level was (3.78 ± 1.30) µg/L in patients receiving plasma transfusion, while (3.91 ± 1.49)µg/L in no-plasma-transfusion group (P > 0.05). Coagulation factors II, VII, IX and X activity which decreased significantly before treatment returned to normal range after one week use of vitamin K, leading to complete correction of prolonged APTT and PT (>100 seconds).
CONCLUSIONS: The PIVKA-II level in ADVKCF patients is significantly higher than that of healthy subjects within one week treatment of vitamin K, which is not influenced by plasma transfusion. This study suggests that PIVKA-II is a more sensitive parameter than APTT, PT and the activity of coagulation factor, which could be a valuable factor in the early diagnosis of ADVKCF.
