SUMMARY BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections can affect the nervous system, triggering problems such as the Guillain-Barre Syndrome (GBS), an association that can bring complications to the patient. OBJECTIVE: This scoping review aimed to clarify the clinical features and analyze patients with GBS associated with SARS-CoV-2 infection, looking at morbidity, mortality, and neurological outcomes. SEARCH STRATEGY: The search was conducted through Medline, Web of Science, Embase, CINAHAL, Latin-American and Caribbean Literature in Health Sciences (LILACS), clinicaltrials.gov, SCOPUS, and the Cochrane Central Register of Controlled Trials. SELECTION CRITERIA: Observational studies, published after 2019, describe patients with GBS associated with SARS-CoV-2 infection. There were no language restrictions while selecting the studies. DATA COLLECTION AND ANALYSIS: Three authors, Kleyton Santos de Medeiros, Luíza Thomé de Araújo Macêdo, and Wederson Farias de Souza, independently screened the search results using titles and abstracts. Duplicate studies were excluded. The same authors then went through the entire text to determine whether the studies met the inclusion criteria. Discrepancies were resolved by other reviewers, Ana Paula Ferreira Costa, Ayane Cristine Sarmento, and Ana Katherine Gonçalves. Finally, the selection of the studies was summarized in a PRISMA flow diagram. MAIN RESULTS: Main manifestations were fever, coughing, dyspnea, sore throat, ageusia, anosmia, and respiratory failure, in addition to paresthesia of the upper and lower limbs, tetraparesis, facial diplegia, areflexia, asthenia, mastoid pain, acute ataxia, fatigue, numbness, swallowing disorder, and moderate low back pain. CONCLUSION: Coronavirus disease 2019 (COVID-19) can trigger the GBS, despite the few studies on this topic. Patients had clinical manifestations of COVID-19 infection and neurological manifestations characterizing GBS.

SUMMARY BACKGROUND: Although much has been studied about the SARS-Cov-2 virus, its effects, and the effectiveness of possible treatments, little is known about its interaction with other infectious diseases. OBJECTIVE: The aim is to study its clinical features and morbidity, and mortality outcomes of COVID-19 patients with HIV/AIDS coinfection. DATA SOURCES: MEDLINE, Web of Science, Embase, CINAHL, LILACS, Scopus, ClinicalTrials.gov, and Cochrane. STUDY ELIGIBILITY CRITERIA: Atudies in any language, published after 2019, were describing COVID-19 patients with HIV/AIDS. STUDY APPRAISAL: JBI Levels of Evidence, Joanna Briggs Institute. SYNTHESIS METHODS: As shown in the PRISMA flow diagram, two authors separately screened the search results from the obtained titles and abstracts. RESULTS: Chest CT was observed in patients with pneumonia by SARS-CoV-2 with findings of multiple ground-glass opacities (GGO) in the lungs, there is a need for supplemental oxygenation. One patient developed encephalopathy and complicated tonic-clonic seizures; four patients were transplanted (two, liver; two, kidneys), one patient developed severe SARS-CoV-2 pneumonia and 30 patients died (mortality rate, 11%). CONCLUSION: HIV did not show any relevance directly with the occurrence of COVID-19. Some studies suggest that HIV-1 infection through induction levels of IFN-I, may to some extent, stop the apparent SARS-CoV-2 infection, thus leading to undetectable RNA. Moreover, some authors suggest retroviral therapy routinely used to control HIV infection could be used to prevent COVID-19 infection.
