A novel nonpsychotropic cannabinoid, HU-211, in the treatment of experimental pneumococcal meningitis.

Abstract

“Typical features of pneumococcal meningitis have been demonstrated in rats inoculated with Streptococcus pneumoniae. HU-211, a novel noncompetitive N-methyl-D-aspartate antagonist recently demonstrated to inhibit tumor necrosis factor-alpha production under various conditions, improves recovery in some experimental models of brain injury. The present study tested the efficacy of HU-211 in combination with antimicrobial therapy in reducing brain damage in experimental pneumococcal meningitis. S. pneumoniae-infected rats were treated with saline alone, ceftriaxone alone, or with combination of ceftriaxone and HU-211 18 h after inoculation of the bacteria. Brain edema and blood-brain barrier impairment 48 h after infection were significantly (P<.05) reduced suggest that HU-211 when given concomitantly with antibiotics attenuates brain damage in the rat model of pneumococcal meningitis.”

Cannabidiol reduces host immune response and prevents cognitive impairments in Wistar rats submitted to pneumococcal meningitis.

 European Journal of Pharmacology “Pneumococcal meningitis is a life-threatening disease characterized by an acute infection affecting the pia matter, arachnoid and subarachnoid space. The intense inflammatory response is associated with a significant mortality rate and neurologic sequelae, such as, seizures, sensory-motor deficits and impairment of learning and memory.

The aim of this study was to evaluate the effects of acute and extended administration of cannabidiol on pro-inflammatory cytokines and behavioral parameters in adult Wistar rats submitted to pneumococcal meningitis.

The extended administration of cannabidiol at different doses reduced the TNF-α level in frontal cortex. Prolonged treatment with canabidiol, 10mg/kg, prevented memory impairment in rats with pneumococcal meningitis.

Although descriptive, our results demonstrate that cannabidiol has anti-inflammatory effects in pneumococcal meningitis and prevents cognitive sequel.”  https://www.ncbi.nlm.nih.gov/pubmed/23085269

“Although descriptive, our results demonstrate that chronic treatment with CBD plays an anti-inflammatory role in pneumococcal meningitis. Furthermore, it prevents cognitive damage, possibly representing a new pharmacological approach towards pneumococcal meningitis.” https://www.sciencedirect.com/science/article/pii/S0014299912008485?via%3Dihub
