This study retrospectively investigated the clinical characteristics and treatment efficacy of Japanese children with PFAPA syndrome. The results showed that pharyngitis is the most frequent symptom associated with fever, and cimetidine is a safe and effective initial treatment option.
Background Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome is an autoinflammatory disease occurring in children. Although PFAPA is the most common periodic fever syndrome found in children, there are only a few studies defining the clinical characteristics and the efficacy of treatment strategies among Japanese children. This study aimed to clarify the demographic characteristics and clinical features of patients with PFAPA syndrome and to evaluate treatment efficacy. Methods We retrospectively reviewed the clinical features of children with PFAPA who visited Saitama Children's Medical Center between January and December 2019. We also evaluated treatment strategies and their efficacy; abortive treatment with corticosteroids, prophylaxis with cimetidine or colchicine, and surgical management with tonsillectomy. Results A total of 100 Japanese children (61% male) with PFAPA were included. Median age of onset was 3 years, median duration of fever episodes was 5 days, and median interval between episodes was 4 weeks. The symptoms (frequencies) were pharyngitis (89%), exudate on tonsils (71%), cervical adenitis (50%), and aphthous stomatitis (49%). Approximately 37% of patients took prednisolone for aborting fever attacks, showing a 100% response; 93% were treated with cimetidine, showing an 79.6% response, and 18% were treated with colchicine, showing a 66.7% response. Only one patient underwent tonsillectomy. Conclusions Among Japanese children with PFAPA, 28% of them were >= 5 years with a male predominance. Pharyngitis is the most frequent symptom associated with fever. Cimetidine is suitable for initial therapy because of its safety and efficacy.
