Dear Sir,
Dengue is an important tropical infection that can have several clinical presentations. Cutaneous hypersensitivity is an important finding that is not frequently mentioned. According to the recent report by Karoli et al., cutaneous hypersensitivity can be seen in 16% of the infected cases. [1] The question is whether the dengue virus protein can act as an allergen or not. To answer this question, the author used the standard bioinformatics allergenicity testing, EVALLER (Uppsala Biomedical Centre, Uppsala, Sweden) [2] to test the genome polyprotein of dengue virus (Accession: P29990.1). The study revealed that the genome polyprotein of dengue virus was not an allergen. However, it had close similarity to the allergen vacuolar serine protease (Penicillium chrysogenum). [3] The mentioned allergen has a strong relationship with immunoglobulin E (IgE) hypersensitivity, and this might be an explanation for cutaneous hypersensitivity in dengue. This is a topic that should be further investigated.
