Q: 32 years old female is admitted to ICU with aplastic crisis with a recent history of intrauterine fetal demise. Subsequent workup leads to the diagnosis of Parvovirus B19. All of the following are considered among the five major syndromes of Parvovirus B19 EXCEPT?
A) Fifth disease (in children)
C) Transient aplastic crisis
D) Fetal infection
E) Pure red blood cell aplasia
Parvovirus B19 continues to be an important discussion in medicine as 50 percent of child-bearing age women worldwide lack measurable IgG to parvovirus B19.
There are five established syndromes associated with parvovirus B19, which are
- Fifth disease/erythema infectiosum in children
- Transient aplastic crisis, occurs usually in patients with chronic hemolytic disorders
- Fetal infection manifesting as non-immune hydrops fetalis, intrauterine fetal death, miscarriage, or cardiomyopathy
- Pure red blood cell aplasia in immunocompromised hosts
Myocarditis manifesting as dilated cardiomyopathy or left heart failure has been reported but not established as a definite syndrome.
