The distribution of CD3+, CD4+, CD8+, CD19+, CD16+, and CD25+ lymphocyte populations in peripheral blood as well as the plasma concentrations of interleukin-1 alpha (IL-1 alpha), and IL-2 and tumor necrosis factor alpha (TNF-alpha) were investigated in 25 children with acute rheumatic fever (ARF) at the time of admission and after 3 months and in 15 children with chronic rheumatic heart disease (CRHD) and in 15 children with streptoccocal pharyngitis (SP) in order to determine changes in lymphocyte subsets and cytokine concentrations occurring during different stages of the disease. The percentages and absolute counts of CD4+, CD16+, CD25+ cells, the ration of CD4/CD8 and plasma concentrations of IL-1 alpha and IL-2 in patients with ARF were significantly higher at admission than 3 months later. These levels were also significantly higher than in patients with CRHD, SP, or normal controls. Production of IL-2 in ARF and CRHD patients directly correlated with the percentages of CD4+ and CD25+ cells. According to our results, the evidences of increased cellular immune response in ARF are increased percentages CD4+ and CD25+ cells, CD4/CD8 ratio, and increased plasma concentrations of IL-1 alpha and IL-2. Furthermore, activation of cellular immune response was not present throughout all stages of rheumatic heart disease and also in SP.

PFAPA syndrome is characterized by periodic episodes of high fever, aphthous stomatitis, pharyngitis, and/or cervical adenitis. It is of unknown etiology and manifests usually before 5 years of age. We determined serum and intracellular cytokine levels in six PFAPA patients (4 males, 2 females, mean age 8 years (+/- 1.2 SEM), range 4-13) during the symptom-free period as well as 6-12 hours and 18-24 hours after fever onset. Values were compared to age-matched, healthy controls. Febrile PFAPA attacks led to a significant increase in IL-6 and IFN-gamma serum concentrations compared to symptom-free periods and to controls, with IL-1beta, TNF-alpha and IL-12p70 levels being significantly higher than in controls. Lymphocytic IFN-gamma and CD8+ IL-2 production was consistently significantly elevated compared to healthy children. During the asymptomatic period, serum concentrations of IL-1beta, IL-6, TNF-alpha and IL-12p70 were significantly increased compared to controls. Intracellular TNF-alpha synthesis was not elevated at any time point. Soluble TNFRp55 levels were even lower in between febrile episodes, reaching values comparable to controls during attacks, whereas soluble TNFRp75 levels increased during attacks compared to healthy children. Anti-inflammatory IL-4 in serum was at all times lower in PFAPA patients compared to controls with no difference in levels of intracellular IL-4 and IL-10 or serum IL-10. The observed increase of pro-inflammatory mediators, even between febrile attacks, suggests a dysregulation of the immune response in PFAPA syndrome, with continuous pro-inflammatory cytokine activation and a reduced anti-inflammatory response.
