Periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome is the most common periodic fever syndrome during early childhood period with regular febrile attacks of sterile upper airway inflammation. The cessation of attacks following tonsillectomy points to fundamental role of tonsil tissue on etiopathogenesis of disease, which is not clarified satisfactorily. The aim of this study is to explore the immunological basis of PFAPA by evaluating the cellular properties of tonsils, and microbial exposition such as Helicobacter pylori on tonsillectomy materials. The paraffinized tonsil samples of 26 PFAPA and 29 control patients with obstructive upper airway disorder were compared in terms of immunohistochemical staining features including CD4, CD8, CD123, CD1a, CD20, and H. pylori. The median number of CD8+ cells was 1485 (1218-1287) in PFAPA while it was 1003 (852-1261.5) in control group and the difference was statistically significant (p=0.001). Similarly, CD4+ cell counts were statistically higher in PFAPA group than control (833.5 vs 622). The ratio of CD4/CD8 did not differ between two groups; also, there was no statistically difference in terms of the other immunohistochemical staining results, such as CD20, CD1a, CD123 and H. pylori. This is the largest number of pediatric tonsillar tissue study of PFAPA patients in current literature and we emphasized the triggering effects of CD8+ and CD4+ T-cells on PFAPA tonsils. • The cessation of attacks following tonsillectomy points to fundamental role of tonsil tissue on etiopathogenesis of disease, which is not clarified satisfactorily. • In current study, 92.3% of our patients did not experience any attacks following operation similarly with literature. • We observed the increased number of CD4+ and CD8+ T cell counts on PFAPA tonsils compared to control group and emphasized the active role of both CD4+ and CD8+ cells localized on PFAPA tonsils in immune dysregulation. • Some other cell types evaluated in this study such as CD19+ (B cells), CD1a (dendritic cells), and CD123 (IL-3 receptors, for pluripotent stem cells) and H. pylori did not differ in PFAPA patients compared to the control group.

A novel assessment tool for clinical care of patients with autoinflammatory disease: juvenile autoinflammatory disease multidimensional assessment report.

To develop and test a new multidimensional questionnaire for assessment of children with auto-inflammatory disease (AID) such as FMF, PFAPA, HIDS, TRAPS in standard clinical care. The juvenile auto-inflammatory disease multidimensional assessment report (JAIMAR) includes 16 parent or patient-centered measures and four dimensions that assess functional status, pain, therapeutic compliance and health-related quality of life (physical, social, school, emotional status) with disease outcome. It is proposed for use as both a proxy-report and a patient self-report, with the suggested age range of 8-18 years for use as a self-report. 250 children with FMF were included in the study. Total of 179 forms were filled up by parents and patients, and 71 forms were filled up by parents having children less than 8 years. Completing and scoring the JAIMAR can be done in 15 minutes. For the JAIMAR's dimensions, the Cronbach's alpha coefficient for internal consistency was between 0.507-0.998. There was a significant and a positive correlation between the test-retest scale scores (ICC=0.607-0.966). Concerning construct validity, all factors loadings were above 0.30. For the criterion validity, the correlation level between each dimension and the related scale ranged from medium (r=0.329, p<0.0001) to large (r=0.894, p<0.0001). The parents' proxy-reported and children's self-reported data were outstandingly concordant (r=0.770-0.989). The development of the JAIMAR introduces a new and multi-dimensional approach in paediatric rheumatology practice. It is a new tool for children with auto-inflammatory dis-ease and it may help enhance their quality of care.
