As prognosticator of DHF other studies had recommended some host factors i.e.
(a) soluble vascular cell adhesion molecule 1,
(b) dengue-virus non-structural protein and
(c) soluble tumor necrosis factor-receptors [25,26].
In this study PAIgM level increased was highly specific (92.5%) although its sensitivity was relatively low (32%), for the development of DHF throughout acute secondary phase infection.
