Elevation of Serum Levels of High-Sensitivity Procalcitonin, C-reactive Protein, and Amyloid A in a Prepubertal Child with Mumps Orchitis.

BACKGROUND: Serum CRP concentrations are significantly elevated at the acute phase in patients with mumps orchitis, but little is known currently about other inflammatory biomarkers.

METHODS: We report the measurements of serum inflammatory biomarkers [high-sensitivity procalcitonin (hs-PCT), C-reactive protein (CRP) and amyloid A] in a child with mumps orchitis.

RESULTS: The patient's serum levels of CRP, hs-PCT, and amyloid A were highly increased at the acute phase, but returned to normal levels at convalescence.

CONCLUSIONS: This case suggests that hs-PCT and amyloid A may not be useful for distinguishing between mumps orchitis accompanied by highly elevated serum concentrations of CRP and systemic bacterial infections.
