Rotavirus infection is a major cause of gastroenteritis, which occurs mainly in children. Liver dysfunction due to rotavirus gastroenteritis has been reported; however, acute hepatitis due to this disease is very rare. We present a rare case in which rotavirus gastroenteritis led to sequential diagnosis of acute hepatitis and systemic primary carnitine deficiency (CDSP) in a 1-year-old girl. The patient's symptoms (hypoglycemia, hepatomegaly, and elevated levels of serum transaminases and creatinine kinase) suggested a steatosis causing liver dysfunction. She was initially considered to have a beta oxygenation defect or secondary carnitine deficiency caused by pivalic acid-containing antibiotics; however, repetitive carnitine analysis and free carnitine clearance measurement confirmed primary carnitine deficiency (carnitine transporter deficiency). Children with severe liver dysfunction due to rotavirus infection and presenting with liver steatosis should undergo blood acyl carnitine analysis to detect potential carnitine or other beta oxidation deficiencies, especially if newborn screening for these diseases is not available.
