Article Abstract
Introduction: Parvovirus B19V has been shown to be associated with end-stage renal disease (ESRD) with increased risk of post-infection anemia, especially in hemodialysis (HD) patients. This effect may be due to immunosuppression, insufficient erythropoietin, or short lifespan of red blood cells. Therefore, parvovirus infection should be investigated in this group of patients suffering from anemia or pancytopenia. We assessed the frequency of parvovirus B19 in HD patients attending Suez Canal University Hospital and analyzed the correlation of this infection with hematological parameters in those patients compared with normal individuals.
Methods: We recruited 80 ESRD patients on hemodialysis and 70 healthy controls. History-taking, full examination, and complete blood count (CBC) were performed for all study subjects. Parvovirus B19 detection was performed through polymerase chain reaction (PCR), which included the QIAamp DNA Mini Kit for extracting DNA, which was amplified using TaqMan Universal Master Mix and detected using TaqMan MGB probes by real-time PCR using Rotor Gene Analyzer (6000).
Findings: HD patients had a significantly higher frequency of B19V infection than the control group (p = .02). We also found that parvovirus B19-infected HD patients had significantly lower CBC values than uninfected patients.
Conclusion: The frequency of parvovirus B19 was significantly higher in HD patients and was associated with lower hematological parameters than in uninfected patients, suggesting a significant role of this virus in the pathogenesis of anemia and/or pancytopenia in ESRD.

The development of a protective HIV vaccine remains a challenge given the high antigenic diversity and mutational rate of the virus, which leads to viral escape and establishment of reservoirs in the host. Modern antigen design can guide immune responses towards conserved sites, consensus sequences or normally subdominant epitopes, thus enabling the development of broadly neutralizing antibodies and polyfunctional lymphocyte responses. Conventional epitope vaccines can often be impaired by low immunogenicity, a limitation that may be overcome by using a carrier system.

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.
