ABSTRACT
COVID-19 is a multisystem disease with considerable heterogeneity of manifestations, including neurological. Neurological manifestations occur in up to 2/3 of patients in the acute phase and include non-specific, central nervous system and peripheral nervous system disorders. This is potentially explained because the SARS-CoV-2 virus has neuroinvasive properties, either directly by retrograde transport via nerve terminations or hematogenous dissemination, and induces neuroinflammation. The persistence of the SARS-CoV-2 in the nervous tissue for an extended period combined with secondary changes determined by neuroinflammation and hypoxia could be potential explanatory mechanisms for the longCOVID neurological manifestations, which occur even more often than those in the acute phase of COVID-19. Since available specialized therapies against neurological manifestations are still lacking, existing treatment options directed against viral invasiveness, the effects of immune dysregulation and hypercoagulable state, along with supportive measures to combat hypoxia, could serve as an efficient treatment for patients with COVID-19 and neurological manifestations. By preventing the SARS-CoV-2 from affecting the nervous tissue in the acute phase, it could also be possible to avoid longCOVID neurological impairment and probably the potential development of neurodegenerative diseases.

ABSTRACT
Cytokine storm seems to be one of the main culprits for developing a severe form of COVID-19, IL-6 being one of its basic components. Therefore, currently, tocilizumab is widely studied as a powerful treatment in patients with severe forms of COVID-19. Our aim was to determine whether it could potentiate a favourable outcome in such patients. We conducted a retrospective observational study including all consecutive admitted patients with confirmed SARS-CoV-2 infection that received treatment with tocilizumab in the period between 01.05-23.08.2020 in Matei Bals National Institute for Infectious Diseases and Neurology Department of the Colentina Clinical Hospital in Bucharest, Romania. 22 patients were enrolled with a severe form of COVID-19, predominantly women, with an average age of of 61.72 ± 14.5 years. The fatality rate was 31.81%. It was observed that following tocilizumab administration, patients presented improvement in the majority of the studied parameters, statistically significant in the case of fibrinogen, C reactive protein and blood oxygen level (p < 0.05). Tocilizumab might be regarded as a valuable drug in the management of severe SARS-CoV-2 infection. © 2020, Romanian Society for Pharmaceutical Sciences. All rights reserved.
ABSTRACT
The novel coronavirus has generated the Coronavirus Disease 2019 (COVID-19) pandemic, which has become the new challenge for the healthcare systems, since there is no etiological treatment and the infectiousness of SARS-CoV2 is exceeding the expectations. Therefore, various treatments have been tried in an attempt to stop the spread of the virus and to enhance the early recovery of the patients. Hydroxychloroquine, an antimalarial drug used for decades, has been one of the first drugs tried to reduce the infectivity of the virus. First data were promising, but afterwards, adverse events and long-term evolution of patients outweighed the potential benefits, and its utility was questioned. In this article we are reviewing literature regarding the use of Hydroxychloroquine during the COVID-19 pandemic and we present the experience of its use in the Neurology Department in Colentina Clinical Hospital, Bucharest, Romania.
