Parvovirus B19 infection is asymptomatic in the majority of cases, but the are several well-known clinical manifestation. In adults transient aplastic crisis, chronic anemia, arthropathy, meningitis, encephalitis, myocarditis and acute hepatitis have been described. In this paper the Authors report two cases - arthropathy and acute hepatitis - of Parvovirus B19 infection in adults.

Background: Nonenveloped viruses, such as hepatitis A virus (HAV) and parvovirus B19 (B19V), are not inactivated by detergents and solvents commonly used to manufacture plasma derivatives. Cases of transfusion-transmitted HAV and B19V have already been described in several countries. This study aimed to determine the incidence of HAV and B19V asymptomatic infections in blood donors from Rio de Janeiro and evaluate the residual risk of transmission to blood derivative recipients.

Parvovirus B19 (B19V) presents a significant concern in the context of blood transfusion safety, given its potential for transmission through contaminated blood products, and the increased viral circulation recently reported across Europe. This study examines the recent epidemiological trends of B19V in Italy, where a notable increase in B19V-positive plasma units was observed during early 2024. While routine NAT testing for B19V in individual blood donations is not currently justified, the existing screening protocols for plasma intended for industrial fractionation are crucial to ensure the safety of plasma-derived medicinal products.

Collapsing glomerulopathy (CG) has a severe course typically associated with viral infections, especially HIV and parvovirus B19, systemic lupus erythematosus (SLE), among other etiologies. A 35-year-old woman with recent use of a JAK inhibitor due to rheumatoid arthritis presented with a 2-week history of fever, cervical adenopathy, and facial erythema. After admission, anemia, hypoalbuminemia, proteinuria, and severe acute kidney injury were noted.
