OBJECTIVES: To describe a cohort of pediatric patients diagnosed with periodic fever aphthous stomatitis, pharyngitis and adenitis (PFAPA) and familial Mediterranean fever (FMF) and compare them with children diagnosed solely with PFAPA (sPFAPA).
STUDY DESIGN: Clinical, laboratory, and genetic data of all pediatric patients diagnosed with sPFAPA or PFAPA/FMF were retrospectively collected from 2 primary Israeli medical referral centers and compared.
RESULTS: Of 270 patients with PFAPA, more than one-half were of Mediterranean ancestry. Among patients with PFAPA, 51 (18.9%) also were diagnosed with FMF (PFAPA/FMF). Genetic data on the 9 most common MEFV variants were available for 45 children (88%) in the PFAPA/FMF group. Two variants were found in 15 children (33.3 %), 1 variant was found 27 patients (60%), and 3 patients (6.6%) had no variants. Abdominal pain, myalgia, and arthralgia each were more commonly reported in the PFAPA/FMF group compared with the sPFAPA group (90% vs 49% [P < .0001]; 46% vs 23% [P = .02]; and 30% vs 17% [P = .049], respectively). Colchicine was more commonly prescribed for the PFAPA/FMF group compared with the sPFAPA group (82% vs 29%; P < .0001), but alleviation of PFAPA symptoms with colchicine was similar between groups (75% vs 63%; P = .23).
CONCLUSION: We show a strong association between 2 common autoinflammatory syndromes, PFAPA and FMF, in patients from Mediterranean ancestry. Clinicians should be aware that presentation of 1 disease may clinically evolve into another. The association between PFAPA and FMF poses the question similar pathogenesis and genetic influence of the MEFV gene on PFAPA.
