Infectious Disease Compendium

Hepatitis

Diagnosis

Inflammation of the liver.

Epidemiologic Risks

Depends on the etiology, many infections can involve the liver, the main ones being viral.

Microbiology

Brucellosis, Cytomegalovirus, Epstein-Barr virus, Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, Hepatitis E, Herpes simplex virus, Leptospirosis, Lyme disease, Q fever, Syphilis (esp in HIV), Yellow fever at a minimum, the number of infections that can acutely involve the liver is, well, all of them. Just about.

Empiric Therapy

Depends on the infection.

Pearls

In HIV patients with unexplained increased ALT, chronic Hepatitis E was found in 2.6%, so it wasn't so unexplained, was it?

Rants

Do not forget your damn vaccines. Have you had your A? Your B? No? Moron.
