Parvovirus B19 (B19V) is a significant pathogen responsible for a wide range of clinical manifestations, particularly in children and pregnant women. While B19V is most commonly recognized as the cause of Fifth disease, a mild erythematous illness in children, its clinical impact extends far beyond this condition. B19V can lead to severe complications, including transient aplastic crisis in individuals with chronic hemolytic anemias, arthralgia, and more severe joint diseases.

Several cases of glomerulonephritis occurring after infection with human parvovirus B19 (PVB19) have been reported. However, the pathogenesis and clinicopathological features of PVB19-related glomerulonephritis remain elusive. We describe the case of a 34 year-old woman who showed nephrotic syndrome and microscopic hematuria 10 days after PVB19 infection.

Human parvovirus B19 typically causes erythema infectiosum, but unusual exanthems and hemorrhagic manifestations, such as purpuric-petechial rashes, have also been reported. PVB19-associated purpuric-petechial eruption (PAPPE) should be recognized as a distinct clinical feature of primary parvovirus B19 infection and considered in the differential diagnosis of patients with febrile purpura. This report aims to highlight several scenarios of B19V-associated petechial and purpuric rashes, which may present to pediatric departments during outbreaks.

Myasthenia gravis (MG) is a rare autoimmune disorder characterised by muscle weakness resulting from autoantibody-mediated disruption of the neuromuscular junction. Notably, it is also frequently associated with thymic pathology. This study explores the relationship between MG and DNA viruses in the thymus, employing targeted NGS and qPCR to analyse thymic tissue samples from both MG patients and healthy controls.

Introduction: parvovirus B19 (B19V) infection during pregnancy can be transmitted to the fetus and cause serious complications such as fetal hydrops and stillbirth. The preexistence of specific IgG prevents vertical transmission. Seroprevalence in fertile age is variable (50-70%) and depends on the region/viral circulation, in addition to factors such as maternal age and frequent exposure to children.
