More infoThere are physiological changes in the hepatobiliary system during pregnancy. However, there are also pregnancy-related liver diseases, which occur in up to 3% of all pregnancies and can have potentially serious consequences for the mother and fetus. The most frequent are hyperemesis gravidarum, preeclampsia/eclampsia, elevated liver enzymes and low platelet count syndrome (HELLP), intrahepatic cholestasis of pregnancy (ICP) and acute fatty liver of pregnancy (AFLP). The prognosis depends on timely diagnosis and treatment. This study aimed to report the epidemiological characteristics of liver diseases in a Mexican population of pregnant women.
Materials and PatientsA retrospective descriptive observational study that included information collected from the electronic file of pregnant patients treated at UMAE HGO No. 3, of CMN La Raza, assessed by the Gastroenterology service of HE CMN “La Raza” in the period March 2021- May 2023.
Results142 patients were included, the mean age was 30 years, 54% were multiparous women, 8.4% of the patients were in the first trimester, 27% in the second trimester and 64% in the third trimester. In our total sample, alterations in liver biochemistry that met clinical and biochemical criteria for pregnancy-associated liver disease were analyzed, where 49% reported hypertransaminasaemia due to etiologies such as preeclampsia, HELLP syndrome, metabolic dysfunction associated fatty liver disease (MAFLD) and biliary pathology, 41% met criteria for ICP, 6% hyperemesis gravidarum, 1.4% were diagnosed with portal hypertension and liver cirrhosis, only 0.7% were diagnosed with autoimmune hepatitis and AFLP.
ConclusionsBased on solicited assessments over a 2-year period of women at any stage of pregnancy, hospitalized due to changes in liver biochemistry, most changes occurred In the third trimester of pregnancy, the most frequent disorder was intrahepatic cholestasis of the pregnancy, the rest of the pathologies were included in the hypertransaminasaemia group, where the most frequent causes were: MAFLD and cholelithiasis, less frequently: preeclampsia, HELLP syndrome or intrahepatic bile duct disorders.
