Suzuki H, et al. - Researchers examined the serum amyloid A (SAA) levels in the blood of patients with atopic dermatitis (AD) and cutaneous T-cell lymphoma (CTCL). Findings suggested the SAA levels in blood and the number of white blood cells in peripheral blood and serum sIL-2R levels in CTCL patients to be significantly correlated. Increased levels of SAA were demonstrated by the AD patients without topical steroid treatment and CTCL patients without narrowband ultraviolet B therapy, which suggested that SAA levels may easily fluctuate with treatment. In development of AD and CTCL, a possible contribution of SAA is implied by the findings.
