When pregnant women take kratom, their babies may suffer

Toxicology screens don’t detect kratom, but it can cause withdrawal in newborns

 

BUFFALO, N.Y. — In 2018, two newborn babies in Buffalo experienced withdrawal as a result of their exposure to kratom in utero.

One was described in a case report by University at Buffalo physicians, published earlier this month in the Journal of Neonatal-Perinatal Medicine. It was titled “Natural drugs, not so natural effects: neonatal abstinence syndrome secondary to ‘kratom.’”

“We published this because many physicians are unaware of this new supplement, known as kratom, and how many people—including pregnant women—are using it,” said Praveen Chandrasekharan, MD, lead author, assistant professor of pediatrics at the Jacobs School of Medicine and Biomedical Sciences at UB and attending neonatologist at UBMD Pediatrics and John R. Oishei Children’s Hospital.

Kratom is poorly understood

Derived from the coffee plant and traditionally used in parts of Asia at low doses as a stimulant, not unlike caffeine, kratom (the scientific name is mitragyna speciosa) has become increasingly popular as a supposedly “safe” and natural painkiller. Widely available in health food stores, drugstores and even vending machines without a prescription, the effects of kratom on people who take it are poorly understood.

Few studies have been done on its medicinal properties and how it affects chronic users, said Chandrasekharan. But what is known is a reason for concern. For one thing, the U.S. Drug Enforcement Administration lists kratom as a drug of concern. In addition, the paper describes what the U.S. Food and Drug Administration (FDA) found when it studied kratom using a methodology that predicts biological function based on a compound’s molecular structure.

“The test developed by FDA known as the Public Health Assessment via Structural Evaluation (PHASE) methodology—a tool to help simulate molecular structure— revealed that 22 of the 25 most prevalent compounds found in kratom can bind to opioid receptors, confirming that kratom acts as an opioid,” said Chandrasekharan.

He noted that kratom is becoming more widely used at a time when more pregnant women are using illicit drugs in general. According to the paper, the incidence of newborns going through withdrawal, known as neonatal abstinence syndrome, has been on the rise. But, Chandrasekharan said, it is usually caused primarily by pain medications and antidepressants that are readily detected by standard urine toxicology screening tests.

“The potential for kratom to cause withdrawal in newborns exposed to it may come as a surprise to many pediatricians and neonatologists,” he noted.

UB physicians have already treated two cases of neonatal withdrawal syndrome secondary to (meaning after exposure to) chronic maternal kratom use and have reported one.

Babies undergo withdrawal

Based on the available reports and evidence, typically babies who withdraw after exposure to maternal kratom use during pregnancy exhibit clinical signs associated with opiate withdrawal, including reduced appetite, jitteriness, sneezing and excessive crying. And unless multiple medications were used during pregnancy, results of standard urine toxicology screens could come out normal.

In Buffalo, the babies admitted to Oishei Children’s Hospital were treated with morphine and then gradually weaned off until their signs and symptoms subsided. They were monitored for an additional 48 hours for any signs of withdrawal before being discharged home.

“The fact that kratom doesn’t show up in toxicology screens makes taking a careful medical history all that much more important,” Chandrasekharan stressed. “As of now, there are no screening toxicology tests for kratom. The increasing number of reports, including ours, of neonatal withdrawal syndrome after exposure to chronic maternal kratom makes increased awareness of this condition critical for health care providers.”

Co-authors on the paper are Munmun Rawat, MD, neonatologist and research assistant professor in the Department of Pediatrics in the Jacobs School, Lauren Davidson, DO, former neonatology fellow at UB and Oishei Children’s Hospital; and Sasko Stojanovski, PharmD, clinical staff pharmacist at the hospital.
