Hemophagocytic Lymphohistiocytosis Associated With Parechovirus 3 Infection Academic Article uri icon

abstract

  • Hemophagocytic lymphohistiocytosis (HLH) denotes the common final pathway of a potentially fatal hyperinflammatory condition of diverse etiologies. We describe the first case of documented HLH associated with human parechovirus 3. A monoallelic Ala91Val mutation was found in the PRF1 gene, but the contribution of this mutation to HLH remains controversial. The diagnosis, based on accepted criteria, was established early in the course of the disease and led to successful treatment and complete recovery. The awareness of this new association is clinically important in facilitating early treatment, preventing organ damage, and increasing the likelihood of complete recovery.
