Introduction: Antineutrophil cytoplasmic autoantibodies associated vasculitis (AAV) is characterized by antibodies against antigens in cytoplasmic granules of neutrophils and predominantly affects small vessels. AAV after COVID-19 mRNA vaccination has been reported.
Case Presentation: We report a rare case of AAV in a patient who presented with rapidly progressive glomerulonephritis (RPGN) after Johnson & Johnson COVID-19 vaccine administration.
Discussion: The temporal causal association between autoimmune manifestations like AAV and COVID-19 vaccines can be explained by hypothesized mechanisms like molecular mimicry, defective neutrophilic apoptosis, polyclonal activation, and systemic proinflammatory cytokine response. These mechanisms are likely to trigger autoimmune responses in genetically susceptible individuals. Still there are many research going on to fill the research gap on the development of ANCA associated with COVID-19 vaccines.
Conclusion: Increasing reports of rare adverse effects like AAV following COVID-19 vaccination warrants the further study and evaluation of immune responses induced by those vaccines. Considering the potential severity of COVID-19 and the rarity of the above-mentioned adverse effects, COVID-19 vaccination should not be withheld.

Acute hepatitis of unknown aetiology in children: evidence for and against causal relationships with SARS-CoV-2, HAdv and AAV2.
BMJ Paediatr Open

Background: The cause of acute paediatric hepatitis of unknown aetiology (2022) has not been established despite extensive investigation.
Objective: To summarise the evidence for and against a causal role for human adenovirus (HAdv), adeno-associated virus 2 (AAV-2) and SARS-CoV-2 in outbreaks of paediatric hepatitis in 2022.
Methods: We appraised and summarised relevant evidence for each of the Bradford Hill criteria for causality using quantitative (statistical modelling) and qualitative (narrative coherence) approaches.
SARS-CoV-2 Nsp7 plays a role in cognitive dysfunction by impairing synaptic plasticity.

It has been reported that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can result in long-term neurological symptoms such as cognitive dysfunction, however the specific mechanisms underlying this phenomenon remain unclear. Initially, we confirmed a reduction in the level of synaptic proteins in SH-SY5Y neurons following SARS-CoV-2 infection. SARS-CoV-2 Nsps are crucial for the efficient replication of the virus and play important roles in the interaction between virus and host cell.

Article Synopsis
- Vasculitis is a potential complication of COVID-19, where the virus can trigger or worsen autoimmune diseases like systemic vasculitis.
- The case of an elderly patient with multiple health issues highlighted the connection, as doctors diagnosed vasculitis due to renal function decline and positive antinuclear antibodies.
- A kidney biopsy confirmed focal necrotizing and crescentic glomerulonephritis, emphasizing the need for awareness of COVID-19 related complications and a broad differential diagnosis in recovering patients.
The Association Between Male Viral Infections and Infertility: A Systematic Review and Meta-Analysis.

Infertility affects approximately one-sixth of couples worldwide, with male factors contributing to half of all cases. However, infections, particularly those of reproductive tract, are increasingly recognized as important contributors to male infertility. Therefore, in this meta-analysis, we focused on the impact of various viral infections on male infertility.

Article Synopsis
- Antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV) primarily targets small- and medium-sized arteries, leading to conditions like rapidly progressive glomerulonephritis, particularly affecting the kidneys.
- Infections are known triggers for this autoimmune disorder, and recent studies suggest a link between SARS-CoV-2 infection and acute kidney injury (AKI).
- The text presents a specific case of a 61-year-old man who developed new-onset diffuse proliferative ANCA-associated glomerulonephritis following COVID-19.
