Combination of ganciclovir and trifluridine prevents drug-resistance emergence in HSV-1
Antimicrob Agents Chemother. 2024 Apr 15:e0011024. doi: 10.1128/aac.00110-24. Online ahead of print.ABSTRACTOcular herpes simplex virus 1 (HSV-1) infections can lead to visual impairment. Long-term acyclovir (ACV) prophylaxis reduces the frequency of recurrences but is associated with drug resistance. Novel therapies are needed to treat drug-resistant HSV-1 infections. Here, we describe the effects of trifluridine (TFT) in combination with ACV or ganciclovir (GCV) on HSV-1 replication and drug-resistance emergence. Wild-type HSV-1 was grown under increasing doses of one antiviral (ACV, GCV, or TFT) or combinations thereof ...

Management of Oral Manifestations of Herpes Simplex Virus, Varicella Zoster Virus, and Human Papillomavirus
Compend Contin Educ Dent. 2024 Apr;45(4):192-197; quiz 198.ABSTRACTHuman herpes virus is a family of DNA viruses that includes herpes simplex virus (HSV) and varicella zoster virus (VZV). HSV-1 and HSV-2 are fairly common and result in oral and genital lesions. Recurrent infections of herpes include lesions on the lips resulting in pain and possibly societal stigma, making adequate treatment of these conditions crucial. VZV is the cause of chicken pox and shingles. Acyclovir and other nucleoside analogues have been the gold standard of treatment for HSV and VZV, but newer, more effective treatments are being developed, whi...

Herpes simplex keratitis: A brief clinical overview
World J Virol. 2024 Mar 25;13(1):89934. doi: 10.5501/wjv.v13.i1.89934.ABSTRACTThe aim of our minireview is to provide a brief overview of the diagnosis, clinical aspects, treatment options, management, and current literature available regarding herpes simplex keratitis (HSK). This type of corneal viral infection is caused by the herpes simplex virus (HSV), which can affect several tissues, including the cornea. One significant aspect of HSK is its potential to cause recurrent episodes of inflammation and damage to the cornea. After the initial infection, the HSV can establish a latent infection in the trigeminal ganglion, ...

Machine Learning Exploration of the Relationship Between Drugs and the Blood –Brain Barrier: Guiding Molecular Modification
ConclusionsThe machine learning models developed can accurately predict BBB permeability, and many drug molecules are likely to have increased BBB penetration if the number of Hydrogen Bond Donors and Acceptors are reduced. These findings suggest that molecular modifications can enhance the efficacy of CNS drugs and provide practical strategies for drug design and development. This is particularly relevant for improving drug penetration of the BBB.Graphical Abstract (Source: Pharmaceutical Research)

CNS Viral Infections —What to Consider for Improving Drug Treatment: A Plea for Using Mathematical Modeling Approaches
AbstractNeurotropic viruses may cause meningitis, myelitis, encephalitis, or meningoencephalitis. These inflammatory conditions of the central nervous system (CNS) may have serious and devastating consequences if not treated adequately. In this review, we first summarize how neurotropic viruses can enter the CNS by (1) crossing the blood-brain barrier or blood-cerebrospinal fluid barrier; (2) invading the nose via the olfactory route; or (3) invading the peripheral nervous system. Neurotropic viruses may then enter the intracellular space of brain cells via endocytosis and/or membrane fusion. Antiviral drugs are currently ...
