Neonatal and Maternal Ichthyosiform Dermopathy in Association with Kava Use during Pregnancy.

INTRODUCTION

Kava, a substance derived from the Piper methysticum plant, is enjoying a surge in popularity in the United States due to its purported anxiolytic and analgesic effects. Though ichthyosiform dermopathy is a known adverse effect associated with chronic kava exposure in adults, dermopathy in a newborn due to maternal kava use has not yet been described.

CASE REPORT: This is a case of a 41-year-old woman who was taking a combination kava/kratom product throughout her pregnancy. She developed an ichthyosiform dermopathy that resolved after she stopped using the product postpartum. Her male infant had a neonatal course complicated by both neonatal opioid withdrawal syndrome, attributed to maternal kratom and buprenorphine use, as well as a diffuse ichthyosiform rash similar to descriptions of kava ichthyosiform dermopathy in adults. His neonatal course was complicated by Group B streptococcus and Serratia marscecens bacteremia (treated with antibiotics) and seizures (treated with lorazepam and phenobarbital). His rash resolved completely by day of life 22. At 9-month outpatient follow-up, he had no dermatologic abnormalities or rash recurrence.

DISCUSSION: Maternal kava use during pregnancy may cause fetal dermopathy presenting as an acquired ichthyosis. More public education is needed about the potential consequences of kava use, particularly during pregnancy.
