Abstract
OBJECTIVE AND DESIGN The present study aimed to investigate the neurochemical and behavioral effects of the acute consequences after coronavirus infection through a murine model. MATERIAL Wild-type C57BL/6 mice were infected intranasally (i.n) with the murine coronavirus 3 (MHV-3). METHODS Mice underwent behavioral tests. Euthanasia was performed on the fifth day after infection (5 dpi), and the brain tissue was subjected to plaque assays for viral titration, ELISA, histopathological, immunohistochemical and synaptosome analysis. RESULTS Increased viral titers and mild histological changes, including signs of neuronal degeneration, were observed in the cerebral cortex of infected mice. Importantly, MHV-3 infection induced an increase in cortical levels of glutamate and calcium, which is indicative of excitotoxicity, as well as increased levels of pro-inflammatory cytokines (IL-6, IFN-γ) and reduced levels of neuroprotective mediators (BDNF and CX3CL1) in the mice brain. Finally, behavioral analysis showed impaired motor, anhedonia-like and anxiety-like behaviors in animals infected with MHV-3. CONCLUSIONS In conclusion, the data presented emulate many aspects of the acute neurological outcomes seen in patients with COVID-19. Therefore, this model may provide a preclinical platform to study acute neurological sequelae induced by coronavirus infection and test possible therapies.

[PMID: 39492176 DOI: 10.1016/j.yebeh.2023.109501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 10/17/2023] [Accepted: 10/18/2023] [Indexed: 11/05/2024]
Abstract
Seizures may be one of the neurological consequences of COVID-19. The present study aims to review the prevalence of seizures in COVID-19 patients considering sex and geographical origin. A review protocol was submitted to the PROSPERO database (CRD42021281467). PRISMA statement was used to report the meta-analysis. The authors selected studies for the meta-analysis by searching the principal databases. Studies were eligible if they reported seizures in COVID-19 patients, regardless of study design. Data were analyzed by proportion meta-analysis with a 95 % confidence interval (95 % CI). Cochran's Q and Higgins' I2 were used to measure heterogeneity. R software was used for meta-analysis. Subgroup analyses were carried out for sex, geographical origin of the subjects, and illness severity. A checklist for prevalence studies was used to assess the risk of bias in the included studies. A total of 32 studies (n = 251,997 analyzed patients) were included in this meta-analysis. A prevalence of 1.03 % (95 % CI 0.73 to 1.37, I2 = 93 %, p < 0.001) was found. No statistically significant differences were found in the analysis by geographical subgroups. Men were found to be less likely to had COVID-19 seizures (OR = 0.75, 95 % CI 0.21-2.74), while mildly ill patients were found to be more likely to had COVID-19-induced seizures (OR = 2.08, 95 % CI 0.86-5.06). Our results show a slight prevalence of seizures in COVID-19 patients. In addition, we found that the groups analyzed had differences in the odds of having COVID-19-induced seizures.
