Suzuki H, et al. - Researchers gauged the serum amyloid A (SAA) levels in the blood of patients with atopic dermatitis (AD) and cutaneous T-cell lymphoma (CTCL). SAA levels in blood and the number of white blood cells in peripheral blood and serum sIL-2R levels in CTCL patients were seen to be significantly associated. Increased levels of SAA were demonstrated by the AD patients without topical steroid treatment and CTCL patients without narrowband ultraviolet B therapy, thereby suggesting that SAA levels may easily fluctuate with treatment. A possible contribution of SAA in the development of AD and CTCL was implied by these results.
