Bizarre birth defect is on the rise, the CDC reports

  • COURTESY CENTERS FOR DISEASE CONTROL AND PREVENTION / NATIONAL CENTER ON BIRTH DEFECTS AND DEVELOPMENTAL DISABILITIES

    In gastroschisis, the intestines, and sometime other visceral organs such as the liver and stomach, protrude through a hole next to a newborn’s belly button.

Physicians are seeing more instances of a birth defect in which infants are born with their intestines extruding from the stomach wall. The increase has been driven by a sharp rise in the defect among babies born to young African-American mothers, says a new report by the Centers for Disease Control and Prevention.

Over the 18 years leading up to 2012, the CDC has documented a 263 percent increase in the birth defect among children born to young black mothers, said a report released today by the agency.

Coleen Boyle, director of the CDC’s National Center on Birth Defects and Developmental Disabilities, said it was urgent that researchers find the cause of the defect and determine which women are at greater risk for having babies with the affliction.

In gastroschisis, the intestines, and sometime other visceral organs such as the liver and stomach, protrude through a hole next to a newborn’s belly button.

Though the abnormality can be life-threatening, it can often be fixed soon after birth with surgery to return the organs inside the abdomen and repair the abdominal wall. But because the affected organs are irritated by their exposure to amniotic fluid inside a mother’s uterus, they can twist, swell, shorten and become infected.

As a result, babies born with the defect can have ongoing digestive and feeding problems. Some also have difficulty staying hydrated and absorbing nutrients from food, which can increase the risk for a range of medical problems, including stunted growth and malnutrition.

If the number of exposed internal organs is large, surgery must sometimes be done in stages. Recovery times can be long. Many babies born with the condition, which can be diagnosed during pregnancy by ultrasound, do not leave the hospital for six weeks or more, and their care in neonatal intensive units is costly.

Roughly 2,000 babies are born each year with gastroschisis.

The rise in the defect affected babies born to women across the spectrum of age and ethnicity. But most cases of gastroschisis occur in babies born to mothers younger than 20. The CDC said this fact was unchanged by a notable decline in live births among teen mothers.

Although researchers do not know what causes gastroschisis, they suspect that environmental factors — a mother’s diet, medicines used during pregnancy or exposures to some toxin — may influence the development of a weak abdominal wall sometime early in pregnancy. What those harmful exposures might be, and whether babies born with the defect have some genetic vulnerability, remains a mystery.

CDC epidemiologist Suzanne Gilboa said “we’re really trying to dig into the ‘why’” of gastroschisis in a number of federal-supported studies tracking pregnant women and their babies. Researchers have just a few clues to guide their hunt, Gilboa added. Mothers who consumed alcohol or used tobacco during pregnancy are at greater risk of having a baby with gastroschisis, as are women who had a sexually transmitted disease during pregnancy or who were underweight before pregnancy.

To discern the trend seen in the latest report, epidemiologists analyzed data from 14 states: Arizona, Arkansas, California, Colorado, Georgia, Iowa, Kentucky, New Mexico, New York, North Carolina, Oklahoma, Rhode Island, Texas and Utah. They compared rates of gastroschisis in the 1995-2005 period with rates seen during the 2006-2012 period.

    • One cup of OJ contains 75 mcg of folic acid. Daily requirement is 400 mcg. So need supplementation. My Centrum Senior contains 300 mcg so a cup of OJ plus a vitamin is sufficient. Can also eat folic acid rich foods like legumes, whole-grain products, dark greens, liver, poultry, pork and shellfish.

      The Food and Nutrition Board of the Institute of Medicine recommends 400 micrograms of the nutrient every day from the age of 14 years through adulthood. The intake for younger people ranges from 65 micrograms to 300 micrograms.

      Interesting that the mothers who suffer this disorder are predominantly black. Poor self discipline in personal health care.
