Nepeta nuda ssp. nuda L. water extract: Inhibition of replication of some strains of Human Alpha herpes virus (genus Simplex virus) in vitro, mode of action and NMR-based metabolomics

Publication date: Available online 20 January 2020Source: Journal of Herbal MedicineAuthor(s): Anton Hinkov, Petia Angelova, Andrey Marchev, Yordan Hodzhev, Venelin Tsvetkov, Daniela Dragolova, Daniel Todorov, Kalina Shishkova, Veneta Kapchina-Toteva, Renald Blundell, Stoyan Shishkov, Milen GeorgievAbstractNepeta nuda L. has been used in traditional folk medicine for its diuretic, anti-asthmatic, antioxidant, spasmolytic, sedative and analgesic properties (attributed to the nepetalactones). In the present study, water extract from Nepeta nuda ssp. nuda L. was tested in order to study its’ effect on the replication of Human Alpha herpes virus (HHV) type 1, strain F (ACV-sensitive) and type 2, strain DD (ACV-resistant) in vitro. Toxicity was measured at 48 hours (CC50 = 7.35 mg/ml ±0.06) and 72 hours (CC50 = 4.488 mg/ml ±0.308) after infection. The extract showed potent anti-herpesvirus activity in both antiviral tests performed (MTT-based colorimetric assay and yield reduction assay). By the time the extract was added, two experimental arrangements were applied. The antiviral activity increased when water extract was added simultaneously with the inoculation of the cell monolayer (EC50 of 0.66 mg/ml ±0.04 and 0.788 mg/ml ±0.009 for the F and the DD strains, respectively, measured via colorimetric assay). The IC50 value was 0.181 mg/ml ±0.073 and 0.0888 mg/ml ±0.014 for the F...

This study was carried out on 59 subjects, 16 patients with mild persistent asthma,11 patients with moderate persistent asthma, 13 patients with severe persistent asthma, and 19 age and gender matched healthy controls. The HVEM mRNA expressions of all subjects were determined by real time PCR. Correlations between HVEM mRNA expression and fractional exhaled nitric oxide (FeNO), pulmonary function test values, total blood white cell count and differential, total immunoglobulin E (IgE) level, and Asthma Control Test (ACT) score were analyzed respectively. The discrimination abilities of HVEM mRNA between different groups wer...

Mepolizumab is a monoclonal antibody that inhibits IL-5 indicated as a maintenance treatment for severe eosinophilic asthma. Reactivation of the herpes zoster virus is a known adverse reaction of the drug. Here we present a patient who developed HSV transverse myelitis secondary to his mepolizumab treatment for severe asthma.

The patient presented twice with atypical Kawasaki disease (KD) with testing positive for adenovirus, Epstein-Barr virus (EBV) on first presentation with significant neutropenia. Second presentation also had significant neutropenia and testing positive for herpes simplex virus (HSV) with viremia triggering concern for immunodeficiency. Work-up revealed reduced natural killer (NK) cell function.

ConclusionsThe majority of signals regarding asthma therapy in children were already known, but we also identified new signals. We showed that signals can be masked if age stratification is not conducted. Further exploration is needed to investigate the risk and causality of the newly found signals.

Discussion Facial nerve palsy has been known for centuries, but in 1821 unilateral facial nerve paralysis was described by Sir Charles Bell. Bell’s palsy (BP) is a unilateral, acute facial paralysis that is clinically diagnosed after other etiologies have been excluded by appropriate history, physical examination and/or laboratory testing or imaging. Symptoms include abnormal movement of facial nerve. It can be associated with changes in facial sensation, hearing, taste or excessive tearing. The right and left sides are equally affected but bilateral BP is rare (0.3%). Paralysis can be complete or incomplete at prese...

Conclusion: 16 of 19 studies treated by CHM granules only showed positive result in 7 diseases and negative result in 1 disease. 17 of 21 studies treated by combination therapy against conventional therapy showed positive result in 6 diseases and negative result in 3 diseases. However, both the absolute and relative effectiveness of CHM formula granules compared with placebo need to be considered clinically. PMID: 31110552 [PubMed]

AbstractBackgroundPatients with moderate-to-severe atopic dermatitis (AD) have increased infection risk, including skin infections and systemic infections. Immunomodulators (e.g., anti-tumor necrosis factors, anti-interleukin [anti-IL]-23, anti-IL-17, Janus kinase inhibitors) increase risk of infections. Dupilumab (a monoclonal antibody blocking the shared receptor component for IL-4 and IL-13) is approved for inadequately controlled moderate-to-severe AD and for moderate-to-severe eosinophilic or oral corticosteroid-dependent asthma.ObjectiveThe aim was to determine the impact of dupilumab on infection rates in patients w...
