The PAF-AH levels were significantly higher (p = 0.01) in those with DHF (median 112.6, IQR 88.35 to 151.1 ng/ml) when compared to those with DF (median 85.35, IQR 73.2 to 98.3 ng/ml) (Fig. 1B) suggesting that high PAF values were not due to reduced breakdown of PAF. Here, PCLAF is linked to Dengue hemorrhagic fever.
