Resumen
IBARGUENGOITIA-OCHOA, Francisco et al. Perinatal outcomes of patients with intrahepatic cholestasis of pregnancy in a third level center in Mexico. Ginecol. obstet. Méx. [online]. 2021, vol.89, n.10, pp.760-769. Epub 04-Abr-2022. ISSN 0300-9041. https://doi.org/10.24245/gom.v89i10.5664.
OBJECTIVE:
To describe the care, treatment, perinatal outcomes and complications associated with intrahepatic cholestasis of pregnancy.
MATERIALS AND METHODS:
A retrospective and observational case series study of pregnant patients with a diagnosis of intrahepatic cholestasis seen at the National Institute of Perinatology between January 2016 and December 2020. Obstetric characteristics, demographic, clinical, biochemical and treatment data, pregnancy termination and perinatal outcomes were evaluated.
RESULTS:
Sixty-seven cases of intrahepatic cholestasis were analyzed, yielding an incidence of 0.57%. The mean age of the patients was 29.0 ± 6.8 years, 30 of 67 were primigravidases, 12 had a history of intrahepatic cholestasis in the previous pregnancy and 7 had an abortion. The onset of the disease was in the third trimester in 41 of 67 patients. In biochemistry studies 32 of 67 had bile acid values between 10 and 39 μM/L; 12 of 67: 40-99 μM/L and 23 more than 100 (μM/L). Treatment with ursodeoxycholic acid was administered to 63 of 67 and rifampicin to 4 patients. The mean number of weeks of gestation was 35.6 ± 2.0 weeks with a mean weight of 2397 ± 572 g. Amniotic fluid with meconium was found in 10 neonates and growth restriction in 20 of 67; there were 2 recorded abortions.
CONCLUSIONS:
This is the first study carried out in Mexico in which the incidence of the disease is described, and the determination of bile acids is used to establish the diagnosis. Perinatal outcomes coincide with those reported in the literature.
