Acute Hepatitis in Pregnancy: A Case Report

Introduction: Several changes occur in women’s body during pregnancy, as well as several pathologies can arise at this period, such as hepatitis. It is very important to have the correct diagnosis and proper treatment for pregnant women because liver diseases can increase maternal and/or fetal morbidity and mortality rates. Case Report: Patient in the age group 32 years, G2P0A1, thrombophilic, using ASA, enoxaparin, folate, and B-complex, reported jaundice, low fever, and pruritus in the 32nd week of pregnancy. Laboratory exams showed high levels of direct hyperbilirubinemia and aminotransferases, with negative serology results for the most common viruses and autoimmunity markers. Hypervitaminosis B12 was an additional finding; it was canceled. The patient had a satisfactory recovery after support treatment. Discussion: Hepatitis has several etiologies; it is caused by infections, medications, or triggered by the immune system. The main infectious agents causing hepatitis A, B, C, and E; Dengue, Zika, HTLV, cytomegalovirus, toxoplasmosis, rubella, and brucellosis were screened in the reported case – the patient was negative for all of them. Other possible diagnoses, such as acute liver steatosis of pregnancy, portal thrombosis, and autoimmune hepatitis were excluded. Hepatitis caused by medicines was not confirmed because clinical and laboratory exams showed improvement in the patient’s clinical condition even with ASA and enoxaparin administration. The patient had high vitamin B12 level, which can be a liver damage marker. Transaminases and bilirubin showed a progressive decrease after the treatment; both patient and newborn had a satisfactory recovery. The reported condition was caused by a combination of factors, such as pregnancy hormone levels, unidentified infection, and possible predisposition to develop the disease. The patient remains under hematological and hepatological follow up, but there is no record of relapse, so far.
