Biomonitoring of prenatal analgesic intake and correlation with infantile anti-aeroallergens IgE.

An association between prenatal acetaminophen or ibuprofen intake and an increased risk of asthma and increased IgE level in children is discussed in various epidemiological studies. Although the molecular mechanistic link is still unknown, the question whether or not acetaminophen and/or ibuprofen are safe pain medications during pregnancy arose. In this study, we associate maternal acetaminophen and ibuprofen intake during pregnancy and breastfeeding to infantile asthma phenotypes and elevated IgE level.

Assessment of maternal drug intake by urinary bio monitoring during pregnancy and postpartally until the third perinatal year.

Purpose: Although sales of prescribed and over-the-counter (OTC) medication are rising, little is known about individual drug intake. This study was aimed to obtain complementary information about drug intake.

Method: Information on drug utilization was obtained in a female cohort for five different time points (TP): 36th week of pregnancy (n = 622), 7th perinatal week (n = 533), 3rd perinatal month (n = 340), and 1st perinatal (n = 534) and 3rd perinatal year (n = 324) by a validated urine screening method.

Monitoring of drug intake during pregnancy by questionnaires and LC-MS/MS drug urine screening: evaluation of both monitoring methods.

Various studies pointed towards a relationship between chronic diseases such as asthma and allergy and environmental risk factors, which are one aspect of the so-called Exposome. These environmental risk factors include also the intake of drugs. One critical step in human development is the prenatal period, in which exposures might have critical impact on the child's health outcome.
