[Association between glutathione peroxidase levels and clinical manifestations of dengue].

Aim: To evaluate the association between the levels of glutathione peroxidase (GP) and the manifestations and complications of dengue.

[Hemophagocytic syndrome associated with dengue hemorrhagic fever].

The haemophagocytic syndrome is characterised by systemic proliferation of non-neoplastic histiocytes showing haemophagocytosis resulting in blood cytopenia. It has been described in relation to several viruses earlier. We present three patients with haemophagocytic syndrome (HFS) secondary to dengue haemorrhagic fever (DHF) confirmed by standard laboratory tests.
