Elevated Liver Enzymes With Positive Hepatitis B Serology After Intravenous Immunoglobulin Treatment of Guillain-Barré Syndrome.

Intravenous immunoglobulin (IVIG) is used to treat multiple conditions, one of which is Guillain-Barré syndrome. Despite its multiple benefits, IVIG can cause a wide variety of side effects, most of which resolve with supportive care. We present a case in which a patient with new-onset Guillain-Barré syndrome was treated with IVIG and subsequently developed an acute elevation in liver enzymes with positive hepatitis B serology.

Bowel perforation in morbid obesity secondary to COVID-19 infection.

The pathophysiology of SARS-CoV-2 is unique in the different pathways the virus utilizes to induce severe systemic inflammation, leading to a higher potential for critical care requirements and a poorer prognosis. Although there are several risk factors for the development of severe infection, one associated with poorer outcome is obesity. In this report, we present a case of bowel perforation in an obese patient with severe COVID-19 infection.

endocarditis in an immunocompetent host.

This case describes an 83-year-old immunocompetent woman who presented to the emergency department with complaints of nausea, vomiting, and dizziness. She was found to have evidence of embolic stroke secondary to endocarditis. This case emphasizes the challenge of diagnosing fungal endocarditis, as it can be difficult to culture, and the importance of broad differentials even in patients with no obvious risk factors.
