Periodic fever syndrome with aphthous stomatitis, pharyngitis and cervical adenopathy treated with ketotifen – a case report
Background The pathogenesis of PFAPA syndrome is unknown. According to Stojanov et al. cytokine profile in PFAPA syndrome suggests Th1 mediated inflammatory process resulting in continuous inflammation and reduced Th2 anti-inflammatory response. Interferon γ might be responsible for suppressing the production of IL-4 and IL10. Hung et al. showed suppressive effects of ketotifen on the expression of Th1 and Th2 related chemokines of human monocytes.
