CHELATION THERAPY IN THE NEONATAL PERIOD: D-PENICILLAMINE CAN EXERT NEUROPROTECTIVE EFFECTS IN KERNICTERUS AND RETINOPATHY OF PREMATURITY
AbstractThis review covers of the results of previously conducted retrospective and prospective clinical trials and data of Cochrane reviews to examine the effects of D-penicillamine (DPA) for neonatal hyperbilirubinemia and associated low incidence of retinopathy of prematurity (ROP). In the ABO- and Rh-Hemolytic Disease of the Newborn (HDN) DPA significantly reduced the need for both initial and repeated exchange transfusions (ET). In Rh-HDN, almost the half of cases, no ET was performed in the DPA-treated group. Furthermore, this treatment was associated with elimination of all stages of ROP in two trials conducted between 1984 and 1986 in the Department of Pediatrics, Medical University of Debrecen. DPA-therapy of newborn infants may have significant neuroprotective effects in cases jeopardized by bilirubin-induced neurologic dysfunction (BIND) or ROP, which may be related to its capability to alter the nitric oxide (NO) system and to its strong antioxidant effects. It can be assumed that in preventing and treating hyperbilirubinemia, ROP and oxygen toxicity, the mechanism of action of DPA is identical: the protection of biomembranes against lipid peroxidation caused by free oxygen radical. Conclusion: It is important to note that there was no intolerance or short- or long-term toxicity of the medication, in spite of the fact that in the newborn period DPA was used 10-20 times higher doses than those in adult
