Effect of phototherapy on plasma 25(OH)-vitamin D in neonates. 1984

D R Gillies, and A Hay, and M J Sheltawy, and P J Congdon

The possibility that phototherapy may increase plasma levels of 25(OH)-vitamin D was assessed by measuring levels before and after 48 h continuous phototherapy using a standard phototherapy unit (Vickers, Basingstoke , England). There was no significant increase in plasma 25(OH)-vitamin D after 48 h phototherapy and it is concluded that such treatment does not stimulate photobiosynthesis of vitamin D.

D007567	Jaundice, Neonatal	Yellow discoloration of the SKIN; MUCOUS MEMBRANE; and SCLERA in the NEWBORN. It is a sign of NEONATAL HYPERBILIRUBINEMIA. Most cases are transient self-limiting (PHYSIOLOGICAL NEONATAL JAUNDICE) occurring in the first week of life, but some can be a sign of pathological disorders, particularly LIVER DISEASES.

D004872	Ergocalciferols	Derivatives of ERGOSTEROL formed by ULTRAVIOLET RAYS breaking of the C9-C10 bond. They differ from CHOLECALCIFEROL in having a double bond between C22 and C23 and a methyl group at C24.	Calciferols,Vitamin D 2,Ergocalciferol,Vitamin D2,D2, Vitamin

D014807	Vitamin D	A vitamin that includes both CHOLECALCIFEROLS and ERGOCALCIFEROLS, which have the common effect of preventing or curing RICKETS in animals. It can also be viewed as a hormone since it can be formed in SKIN by action of ULTRAVIOLET RAYS upon the precursors, 7-dehydrocholesterol and ERGOSTEROL, and acts on VITAMIN D RECEPTORS to regulate CALCIUM in opposition to PARATHYROID HORMONE.
D015652	25-Hydroxyvitamin D 2	9,10-Secoergosta-5,7,10(19),22-tetraene-3,25-diol. Biologically active metabolite of vitamin D2 which is more active in curing rickets than its parent. The compound is believed to attach to the same receptor as vitamin D2 and 25-hydroxyvitamin D3.	25-Hydroxyergocalciferol,25-Hydroxycalciferol,25-Hydroxyvitamin D2,9,10-Secoergosta-5,7,10(19),22-tetraene-3 beta,25-diol,Ercalcidiol,25 Hydroxycalciferol,25 Hydroxyergocalciferol,25 Hydroxyvitamin D 2,25 Hydroxyvitamin D2
