AI Article Synopsis

  • The text introduces the concept that viral cytopathic changes in sputum cytology have been noted for several viruses, but human metapneumovirus (hMPV) is not well-documented in this context.
  • It presents a case study of a 63-year-old male patient with hMPV, detailing specific cytopathic changes observed in his sputum, like multinucleation and nuclear inclusions.
  • The conclusion highlights the need to recognize hMPV's role in causing these changes and stresses the importance of distinguishing them from similar features caused by other viruses, as this can affect clinical management.

Article Abstract

Introduction: Viral cytopathic changes seen in sputum cytology have been described in association with infection by viruses such as cytomegalovirus (CMV), herpes simplex virus (HSV), adenovirus, and even measles. However, viral cytopathic changes due to human metapneumovirus (hMPV) have not yet been well described in cytology. hMPV is a relatively new entity, discovered in 2001. It is known to cause upper and lower respiratory tract infections in children, the elderly, and immunocompromised patients.

Case Presentation: We describe the viral cytopathic changes seen in sputum in a 63-year-old male patient with known hMPV. These changes include multinucleation, nuclear enlargement, homogenised nuclei, basophilic nuclear inclusions with perinuclear halos, and small eosinophilic cytoplasmic inclusions.

Conclusion: We aim to raise awareness that hMPV can cause viral cytopathic changes and to describe these cytological features, which have been elucidated in only 1 case report thus far. Distinction from other viruses with similar changes, such as HSV and CMV, is important due to their differing clinical implications.

Herpes viruses are highly contagious agents affecting all classes of vertebrates, thus causing serious health, social, and economic losses. Within the One Health concept, novel therapeutics are extensively studied for both veterinary and human control and management of the infection, but the optimal strategy has not been invented yet. Lactic acid bacteria are key components of the microbiome that are known to play a protective role against pathogens as one of the proposed mechanisms involves compounds released from their metabolic activity.

The emergence of RNA viruses driven by global population growth and international trade highlights the urgent need for effective antiviral agents that can inhibit viral replication. Nucleoside analogs, which mimic natural nucleotides, have shown promise in targeting RNA-dependent RNA polymerases (RdRps). Starting from protected 5-iodouridine, we report the synthesis of -substituted-(1,3-diyne)-uridines nucleosides and their phosphoramidate prodrugs.

Photodynamic inactivation (PDI) has been revealed as a valuable approach against viral infections because of the fast therapeutic effect and low possibility of resistance development. The photodynamic inhibition of the infectivity of human herpes simplex virus type 1 (HSV-1) strain Victoria at different stages of its reproduction was studied. PDI activity was determined on extracellular virions, on the stage of their adsorption to the Madin-Darby bovine kidney (MDBK) cell line and inhibition of the viral replication stage by application of two tetra-methylpyridiloxy substituted gallium and zinc phthalocyanines (ZnPcMe and GaPcMe) upon 660 nm light exposure with a light-emitting diode (LED 660 nm).
