Background:
Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist used
for the treatment of type 2 diabetes mellitus (T2DM). So far, few severe side effects have been
reported for it.
Case Presentation:
A 41-year-old woman was admitted to the Emergency Room with diffuse
abdominal pain. The patient had a known case of T2DM, fatty liver disease, and hypertension
and was treated with Metformin, Liraglutide, and Losartan. Her liver functional test (LFT) was
consistent with hepatocellular injury; however, laboratory tests and abdominal ultrasound were
used to rule out autoimmune hepatitis. Due to concerns for drug-induced liver injury (DILL),
liraglutide was discontinued and N-acetyl cysteine was prescribed. On the fifth day of hospitalization, the patient's symptoms resolved and his LFT started to decrease on the sixth day after 2
months, the patient's liver enzyme levels returned to normal.
Conclusion:
Liraglutide is one of the most important drugs in the treatment of T2DM.The most
common side effects of this drug are constipation, nausea, vomiting, diarrhea, indigestion, and
loss of appetite. In rare cases, symptoms of thyroid cancer, pancreatitis, and hypoglycemia have
been reported, however, DILL is one of the extremely rare side effect of Liraglutide. It is important to increase the awareness of physicians about the liver injury of Liraglutide.
