The tumor necrosis factor-alpha-308 A/G genotype was overrepresented among whites with KD who had coronary artery abnormalities compared with those with normal echocardiograms (0.36 versus 0.09; p = 0.044).
These findings indicate that an excessive amount of MMP-9 is present in the plasma during the acute phase of KD, thus suggesting that circulating leucocytes may be a source of the MMP-9 secreted into the circulation.
Although Kawasaki disease (KD) patients demonstrate a drastic increase in serum interleukin-6 (IL-6) during the acute phase that parallels the duration of fever, there were no significant differences in the nucleotide sequence between the KD patients and normal control group.
Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is a dominantly inherited autoinflammatory syndrome that results from mutations in TNFRSF1A, the gene that encodes the 55-kdtumor necrosis factor receptor.

Results of this study showed that allele 1 of the 5' promoter (GT)n repeat in the SLC11A1 (formerly NRAMP1) gene, which endows the gene with a weak promoter activity, was highly represented in patients with KD.

CD40L expression on platelets from patients with KD was also significantly higher than in the FC group (8.20 +/- 0.41% vs 1.26 +/- 0.12%) and decreased after IVIG therapy. sCD40L levels were also significantly higher in KD patients with those of FC (9.69 +/- 0.45 ng/mL vs 2.25 +/- 0.19 ng/mL) but were not affected by IVIG treatment 3 days afterward (9.69 +/- 0.45 ng/mL vs 9.03 +/- 0.32 ng/mL).
The frequencies of the DRB1*04051, 0406, and 0901 were high, whereas that of the DRB1*1101 was low among patients with KD as compared with the healthy adults.

The percentage of T-cells bearing TCRBV2 and TCRBV6S5 was high in patients in the acute stage of KD. rSPE-C stimulation of PBMC from healthy donors induced expansion of TCRBV2 and TCRBV6S5-bearing T-cells.
The significantly elevated pro-MMP-9 enzyme and protein levels during the acute phase of KD may reflect vascular remodeling or an inflammatory response to a microbial agent, suggesting a pathophysiological role for MMP-9 in coronary aneurysm formation.
Furthermore, pro-MMP-9 and TIMP-1 protein levels were significantly elevated among KD patients, compared to those of febrile and afebrile non-KD controls.
Monocytes from acute inflammatory illnesses, such as Kawasaki disease and acute infectious diseases, viral or bacterial, produced significant levels of HO-1, as detected by flow cytometry, immunohistochemistry, and reverse transcription polymerase chain reaction.
