Effect of neonatal phototherapy on interleukins

Sedigheh Jahanshahifard, Mousa Ahmadpour-Kacho, Yadollah Zahed Pasha
OBJECTIVE: Phototherapy is the most common treatment used for severe jaundice. There is increasing evidence that phototherapy can directly affect the expression and function of cell surface receptors including adhesion molecules, cytokines, and growth factor receptors. The aim of this study is to investigate the effect of phototherapy use on the levels of interleukin (IL)-1α, IL-6, and tumor necrosis factor (TNF)-α as cytokine expressions from keratinocytes, and also white blood cell counts in the treatment of neonate with hyperbilirubinemia...

BACKGROUND: Most studies regarding the influence of ultraviolet radiation on levels of inflammatory cytokines were conducted mainly in cultures of human keratinocytes or in laboratory animals. Few studies were also performed in human subjects. OBJECTIVES: To investigate the influence of the use of phototherapy on the levels of tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, IL-6, IL-8 such as cytokines expressed from keratinocytes and on the expression of some lymphocyte subsets in the prevention or treatment of neonatal hyperbilirubinemia...

The capacity of peripheral blood mononuclear cells (PBMC) to produce interleukin (IL) IL-1beta, IL-2, IL-3, IL-6, IL-10 and tumor necrosis factor-alpha (TNFalpha) was examined in term newborns with hyperbilirubinemia after 24 hours' exposure to phototherapy (wave length 425-475 nm). The results were compared with those from untreated neonates. Fifty newborns spontaneously delivered at term were included in the study. Blood samples were collected from 20 newborns before and 24 h after phototherapy. The control group consisted of 30 neonates examined on two consecutive days...
