Plasmapheresis for Suspected Drug-Induced Liver Injury During Pregnancy: A Multidisciplinary Diagnostic and Therapeutic Challenge

Résumé fourni par la source

Acute liver injury during pregnancy is rare and predominantly associated with pregnancy-related conditions including acute fatty liver of pregnancy; Hemolysis, Elevated Liver Enzymes and Low Platelets syndrome; intrahepatic cholestasis of pregnancy; and preeclampsia. Drug-induced liver injury (DILI) is a less common and often overlooked cause of acute liver injury in pregnant patients. A literature search on acute liver injury during pregnancy and therapeutic plasma exchange was conducted, revealing the most common causative factors and syndromes. A 39-year-old woman was diagnosed with acute liver injury in the 23rd week of her third pregnancy and, upon extensive differential diagnoses, a suspicion of DILI occurred after the use of methyldopa. Methyldopa, the drug of choice for the treatment of hypertensive disorders of pregnancy, has a high safety profile for the developing fetus and is well tolerated by pregnant women, yet, in susceptible individuals, a hepatotoxic effect may occur. The drug was discontinued and symptomatic treatment with ursodeoxycholic acid and prednisone was implemented with marginal effect. Upon a multidisciplinary joint consultation, plasmapheresis procedures were introduced, granting a significant improvement in the patient's liver function and enabling the continuation of the pregnancy. Plasmapheresis treatment was safely and effectively used for the first time in the therapeutic process in a pregnant patient with DILI. Interdisciplinary cooperation of specialists with gastroenterology, nephrology, and obstetrics expertise is crucial to achieving a timely diagnosis and begin effective treatment for pregnant patients with acute liver injury.
