Among these patients, 63.5% (33 patients) experienced plaque psoriasis flare-ups, 19.2% (10 patients) developed guttate psoriasis, 11.5% (6 patients) progressed to erythroderma, 3.8% (2 patients) presented with plaque psoriasis and pustules, and one patient (1.9%) had an acute generalized pustular psoriasis flare-up. Overall, 63.5% of patients experienced moderate dengue, 30.8% had mild dengue, and 5.8% had severe dengue. Among the 19 patients receiving biologic treatments, 84.2% experienced moderate dengue, while 15.8% had mild dengue. Importantly, none of these patients required hospitalization for severe dengue. In the methotrexate-treated group, comprising seven patients, four experienced mild dengue and three had moderate dengue. Psoriasis flare-ups in this group included two severe cases, five moderate cases, one erythroderma, and six cases of plaque psoriasis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions: and Relevance<\/jats:title>\n                    <jats:p>Dengue infection appears to trigger psoriasis flare-ups in affected individuals. The most commonly observed type was plaque psoriasis. Our findings suggest systemic therapies for psoriasis may not exacerbate dengue severity and could be considered safe.
