Review of published studies of kidney, liver, and gastrointestinal birth defects in fetal alcohol spectrum disorders.

OBJECTIVE

Review of published studies of birth defects of the renal, liver, and gastrointestinal organ systems in subjects with fetal alcohol spectrum disorders (FASD).

METHOD

We searched PubMed (http://www.pubmed.gov) using the following terms: fetal alcohol syndrome and: gastrointestinal tract, kidney, liver, and congenital abnormalities for all years and English only citations.

RESULTS

We located 12 studies of FASD and defects of or functional impairments for the liver, 12 of renal abnormalities, and only two with gastrointestinal defects. We did not identify specific patterns of malformations or functional deficits for any of the three organ systems. The existing literature suggests a series of nonspecific outcomes in FASD.

CONCLUSIONS

Fetal alcohol spectrum disorder includes a diagnostic category of alcohol-related birth defects which is clinically difficult to apply. This study adds to the existing literature on birth defects in FASD which is still very limited. The categorical diagnosis of alcohol-related birth defects requires additional research to determine if a specific pattern of organ specific abnormalities or functional deficits emerges in subjects with FASD.
