RESUMO
To the Editor An elegant study reported dysmorphic cells and syncytia in the deceased's lungs for COVID-19. The authors reasonably considered that most of these syncytia-forming cells were pneumocytes, as identified by specific biomarkers. However, cellular dysmorphism and syncytia are pathological features common in other respiratory infections caused by different viruses, including the human respiratory syncytial virus (HRSV) and Epstein-Barr virus (EBV), as correctly documented...

Objective: This study compared three severity measures for chronic rhinosinusitis with nasal polyps (CRSwNP). The outcome was to identify patients who are eligible for biological therapy. Methods: 330 adult patients with CRSwNP were examined. Nasal polyp score (NPS), sinonasal outcome test (SNOT-22) and clinical-cytological grading (CCG) were compared. Clinical history, past surgery and asthma control test were also considered. Results: Only 45 (13.6%) patients had a contextual positivity to the three severity measures. The concordance among tests was slight/fair. Patients with severe disease (all tests positive) had more impaired parameters. The mixed cytotype (OR = 4.07), nasal obstruction (OR = 10.06), post-nasal drip (OR = 1.98), embarrassment (OR = 2.53) and difficulty falling asleep (OR = 1.92) were significantly associated with severe CRSwNP. Conclusions: To identify candidates for biological therapy, the contextual use of NPS, SNOT-22 and CCG is preferable. In this way, global assessment of CRSwNP, including morphology, inflammation, comorbidity, symptoms and quality of life is possible.
