PFAPA syndrome in a young adult with a history of tonsillectomy.
ABSTRACT Since its clinical definition in 1987, the syndrome called, "periodic fever, aphtous stomatitis, pharyngitis and cervical adenitis" syndrome (PFAPA) has been considered peculiar to pediatric age. In the recent literature there are a few case reports of PFAPA in adults. We describe a case of a 21-year-old female affected by PFAPA who presented a history of tonsillectomy at the age of four. To our knowledge this is the fourth case described with a diagnosis of PFAPA in an adult with a history of tonsillectomy during childhood. Although the role of tonsillectomy in the treatment of PFAPA is still controversial, due to the lack of definitive data in literature, this case suggests that fever episodes may relapse several years after surgery.

ABSTRACT: To investigate clinical presentation, genetic background and cytokine profile of Japanese sporadic cases of periodic fever, aphthous stomatitis, pharyngitis and adenitis (PFAPA) syndrome. Nine PFAPA syndrome patients were recruited. DNA sequence analysis of auto inflammatory disorder susceptibility genes, MEFV, MVK, NLRP3, and TNFRSF1A, were performed. Serum cytokine levels and monocyte IL-1β levels were measured by ELISA. The study population consisted of six males and three females (mean age of onset 26.8 months). Febrile episodes lasted 3-6 days with symptom-free intervals ranging from 2 to 12 weeks. Fever was accompanied by pharyngitis (n = 8), aphthous stomatitis (n = 4), and cervical adenitis (n = 5). White blood cells and C-reactive protein were increased during the attack phase. Mean IgD serum levels were 7.32 ± 9.51 mg/dl during the attack phase, and were mildly elevated in two patients. Heterozygous MEFV, NLRP3 and TNFRSF1A variants were detected in four, one and three cases, respectively. Serum TNF-α and IL-18 levels were elevated during the attack-free and attack periods compared with controls. Other cytokines, IL-1β, IL-1ra, IL-6, and sTNFR1, were only increased during the attack phase. Oral prednisolone was administered to eight patients and immediately reduced fever. Tonsillectomy performed in five patients induced cessation of fever in four patients. One case with repeated fever attacks after tonsillectomy showed increased monocyte IL-1β production, similar to the other active case with genetic variants of auto inflammatory disorder-associated genes. Japanese PFAPA syndrome patients may have cytokine regulation dysfunction as a result of genetic variants of auto inflammatory disorder-associated genes.Journal of Clinical Immunology 04/2014; · 2.65 Impact Factor

ABSTRACT: Autoinflammatory disorders (AIDs) are a novel class of diseases elicited by mutations in genes regulating the homeostasis of innate immune complexes, named inflammasomes, which lead to uncontrolled oversecretion of the proinflammatory cytokine interleukin-1β. Protean inflammatory symptoms are variably associated with periodic fever, depicting multiple specific conditions. Childhood is usually the lifetime in which most hereditary AIDs start, though still a relevant number of patients may experience a delayed disease onset and receive a definite diagnosis during adulthood. As a major referral laboratory for patients with recurrent fevers, we have tested samples from 787 patients in the period September 2007-March 2014, with a total of 1,328 AID-related genes evaluated and a gene/patient ratio of 1.69. In this report, we describe our experience in the clinical approach to AIDs, highlight the most striking differences between child and adult-onset AIDs, and shed an eye-opening insight into their diagnostic process.Clinical Rheumatology 06/2014; · 1.77 Impact Factor
