Antenatal Allopurinol in Intrauterine Growth Restriction

2014-08-27 03:43:43 | BioPortfolio


Growth retardation in utero may be caused by uteroplacental vascular insufficiency. When Doppler ultrasound studies of the umbilical artery are abnormal pathological intrauterine growth restriction (IUGR) can be diagnosed. IUGR fetuses have a higher mortality and morbidity, both perinatally and on the longer term. This is probably due to chronic malnourishment and hypoxia due to placental insufficiency. This placental dysfunction causes generation of harmful free oxygen radicals in the fetus. The IUGR fetus has a diminished antioxidative capacity which means these free radicals cannot be buffered sufficiently. This leads to fetal oxidative stress.

Previous studies have shown that allopurinol can inhibit the cascades that lead to generation of free radicals. High dosed allopurinol also scavenges radicals and binds free iron without adverse effects on the fetus or mother.

As IUGR is associated with placental insufficiency and excessive production of free radicals we hypothesize that antenatal allopurinol administration could lead to a decrease in oxidative stress in the mother and fetus and subsequent improvement of the maternal and/or neonatal outcome.

Medical and Biotech [MESH] Definitions

The failure of a FETUS to attain its expected FETAL GROWTH at any GESTATIONAL AGE.

A condition occurring in FETUS or NEWBORN due to in utero ETHANOL exposure when mother consumed alcohol during PREGNANCY. It is characterized by a cluster of irreversible BIRTH DEFECTS including abnormalities in physical, mental, and behavior development (such as FETAL GROWTH RETARDATION; MENTAL RETARDATION; ATTENTION DEFICIT AND DISRUPTIVE BEHAVIOR DISORDERS) with varied degree of severity in an individual.

A condition of abnormally low AMNIOTIC FLUID volume. Principal causes include malformations of fetal URINARY TRACT; FETAL GROWTH RETARDATION; GESTATIONAL HYPERTENSION; nicotine poisoning; and PROLONGED PREGNANCY.

A condition occurring in untreated or partially treated females with PHENYLKETONURIA when they become pregnant. This may result in damages to the FETUS, including MICROCEPHALY; MENTAL RETARDATION; congenital heart disease; FETAL GROWTH RETARDATION; and CRANIOFACIAL ABNORMALITIES. (From Am J Med Genet 1997 Mar 3;69(1):89-95)

An umbrella term used to describe a pattern of disabilities and abnormalities that result from fetal exposure to ETHANOL during pregnancy. It encompasses a phenotypic range that can vary greatly between individuals, but reliably includes one or more of the following: characteristic facial dysmorphism, FETAL GROWTH RETARDATION, central nervous system abnormalities, cognitive and/or behavioral dysfunction, BIRTH DEFECTS. The level of maternal alcohol consumption does not necessarily correlate directly with disease severity.
