RESUMO

Posterior reversible encephalopathy cases are increasingly being reported in patients affected by COVID-19, but the largest series so far only includes 4 patients. We present a series of 6 patients diagnosed with PRES during COVID-19 hospitalized in 5 Centers in Lombardia, Italy. 5 out of the 6 patients required intensive care assistence and seizures developed at weaning from assisted ventilation. 3 out of 6 patients underwent cerebrospinal fluid analysis which was normal in all cases, with negative PCR for Sars-CoV-2 genome search. PRES occurrence may be less rare than supposed in COVID-19 patients and a high suspicion index is warranted for prompt diagnosis and treatment.

RESUMO

Recently WHO has declared novel coronavirus disease 2019 (COVID-19) outbreak a pandemic. Acute respiratory syndrome seems to be the most common manifestation of COVID-19. Besides pneumonia, it has been demonstrated that SARS-CoV-2 infection affects multiple organs, including brain tissues, causing different neurological manifestations, especially acute cerebrovascular disease (ischemic and hemorrhagic stroke), impaired consciousness and skeletal muscle injury. To our knowledge, among neurological disorders associated with SARS-CoV2 infection, no Posterior Reversible Encephalopathy Syndrome (PRES) has been described yet. Herein, we report a case of a 64-year old woman with COVID19 infection who developed a PRES, and we suggest that it could be explained by the disruption of the blood brain barrier induced by the cerebrovascular endothelial dysfunction caused by SARS-CoV-2.

RESUMO

OBJECTIVE: The introduction of monoclonal antibody (mAb) therapies represents a promising treatment for refractory chronic rhinosinusitis (CRS). We assessed the effects of selected mAbs (omalizumab, mepolizumab, benralizumab) on CRS in severe asthmatic patients in a real-life setting. METHODS: A prospective observational study on severe asthmatic patients, treated with 3 different mAb (omalizumab, mepolizumab, benralizumab), and comorbid CRS was conducted. All patients were followed for 52 weeks. The degree of nasal control, SinoNasal Outcome Test (SNOT) 22, Nasal Polyp Score (NPS), Lund Kennedy Score (LKS) were collected at baseline and at 52-week. RESULTS: 40 patients (33 with nasal polyps) were studied. 33 patients (82.5%) had uncontrolled nasal disease at baseline, and 15 (37.5%) were uncontrolled after 52 weeks. Significant improvement was observed for SNOT 22 (P < 0.001), SNOT 1-12 (P < 0.001) and degree of nasal control (P < 0.001). Differences in NPS (P = 0.130) and LKS (P = 0.124) were not significant. Net change in the above-mentioned parameters among the three treatment groups was not significantly different. CONCLUSIONS: The study shows an improvement of nasal symptoms after 52 weeks of mAb treatment, which was not associated with significant improvement of endoscopic findings. Larger studies are needed to assess the real-life efficacy of mAbs in CRS.
