Hg-CATH and Pb-CATH4 are cathelicidins from and that have been previously identified as potent antibacterial peptides. However, their antiviral properties were not previously investigated. In this study, their activity against the herpes simplex virus (HSV)-1 was evaluated during primary human keratinocyte infection. Both of them significantly reduced HSV-1 DNA replication and production of infectious viral particles in keratinocytes at noncytotoxic concentrations, with the stronger activity of Pb-CATH4. These peptides did not show direct virucidal activity and did not exhibit significant immunomodulatory properties, except for Pb-CATH4, which exerted a moderate proinflammatory action. All in all, our results suggest that Hg-CATH and Pb-CATH4 could be potent candidates for the development of new therapies against HSV-1.

Background: Herpes simplex encephalitis (HSE), caused by herpes simplex virus (HSV) is the most common cause of sporadic encephalitis that often presents as an emergency case of acute or sub-acute nature associated with poor prognosis. Early suspicion and prompt diagnostic testing with adequate antiviral therapy can only reduce morbidity and mortality associated with the disease. This study aims to evaluate the role of serological and molecular diagnosis of encephalitis caused by HSV 1 and 2 for timely detection of the disease.

We report a case of a 49-year-old female with a history of HIV infection for 12 years. The patient had excellent compliance with antiretroviral medications, raltegravir 400 mg twice daily and truvada once daily for HIV. Over the years, she maintained an undetectable viral load with a CD4+ count >200 cells/μL.

Fetal limb anomaly presentation varies greatly. It can present as amelia (complete absence of skeletal part of one or more limb), meromelia (partial absence of skeletal part of one or more limb), phocomelia (only rudimentary limb formed), and minor limb disorders like polydactyly. The complete absence of the four fetal limbs is extremely rare.
