Unlabelled: We report the course of dicygotic twins born preterm after 29 (4)/7 weeks of gestation due to congenital Parvovirus B19 infection causing fetal hydrops with severe anemia in one infant in whom intrauterine transfusion was impossible to perform and high levels of viremia in both infants. After being discharged, they were readmitted at 3 months of age with critical aplastic crisis. Therapy with intravenous immunoglobulin infusion resulted in decreasing viremia followed by stable hemoglobin levels in both infants.
Conclusion: Intravenous immunoglobulin treatment of congenital pure red cell aplasia due to Parvovirus B19 infection in preterm infants seems to be effective to introduce viral remission and to normalize erythropoiesis.

Human Parvovirus B19 (B19V) is rarely observed in patients with Guillain-Barré syndrome. We report the case of a patient with rapidly progressive functional impotence of the limbs. B19V was detected in both blood and CSF samples.

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.

Multiple sclerosis (MS) is a devastating autoimmune disease that leads to the destruction of the myelin sheath in the human central nervous system (CNS). Infection by viruses and bacteria has been found to be strongly associated with the onset of MS or its severity. We postulated that the immune system's attack on the myelin sheath could be triggered by viruses and bacteria antigens that resemble myelin sheath components.
