Аннотация
PURPOSE: Cerebrotendinous xanthomatosis (CTX) is a rare, autosomal recessive bile acid synthesis disorder. Biallelic pathogenic variants in CYP27A1, encoding for sterol 27-hydroxylase, impair cholic acid (CA) and chenodeoxycholic acid (CDCA) synthesis and lead to accumulation of cholestanol and C27 bile alcohols. Treatment with CDCA decreases the accumulation of these harmful metabolites and slows disease progression. Currently, CDCA is contraindicated for use during pregnancy based on animal studies that showed that high-dose CDCA may cause fetal harm when administered to pregnant animals. Data regarding the safety of CDCA treatment in humans are lacking.
METHODS: We present a case series of 19 pregnancies in 9 women with CTX who either received CDCA treatment throughout pregnancy or did not.
RESULTS: In 11 pregnancies where mothers continued CDCA treatment, no complications were reported, and newborns were born at or near full term, with normal birth weight and Apgar scores. In 8 pregnancies where mothers did not receive CDCA, 2 newborns experienced elevated bilirubin soon after birth. One woman who stopped treatment during her pregnancy deteriorated neurologically while off treatment.
CONCLUSION: The data we present support the benefit of continued CDCA treatment in pregnant women with CTX for both the affected women and their offspring.
