RESUMO
PURPOSE: The aim of this study was to assess respiratory function at the time of clinical recovery, 6 weeks, 6 months, and 12 months after discharge in patients surviving to COVID-19 pneumonia. METHODS: Our case series consisted of 13 hospitalized patients with COVID-19 pneumonia. RESULTS: Baseline pulmonary function tests were 55.7 ± 15.6 for FEV1%, 68.6 ± 16.0 for FVC%, and 1.2 ± 0.1 for FEV1/FVC%. Although pulmonary function showed a small improvement after 6 weeks, patients experienced a more significant improvement after 6 and 12 months in FEV1% (95.4 ± 13.7 and 107.2 ± 16.5, respectively; p < 0.001), FVC% (91.3 ± 14.5, and 105.9 ± 15.6, respectively; p < 0.001), and FEV1/FVC% values (1.04 ± 0.04, and 1.01 ± 0.05, respectively; p < 0.001). CONCLUSION: COVID-19 pneumonia may result in significant alterations in lung function, with a mainly restrictive pattern, partly persisting at 6 weeks after recovery from acute phase, but significantly improving during a 12-month follow-up period.

The IL-1 receptor antagonist, anakinra, may represent a therapeutic option for acute respiratory distress syndrome (ARDS) associated with coronavirus disease 2019 (COVID-19). In this study, COVID-19 ARDS patients admitted to the Azienda Socio Sanitaria Territoriale of Lecco, Italy, between March 5th to April 15th, 2020, and who had received anakinra off-label were retrospectively evaluated and compared with a cohort of matched controls who did not receive immunomodulatory treatment. The primary end point was survival at day 28. The population consisted of 112 patients (56 treated with anakinra and 56 controls). Survival at day 28 was obtained in 69 patients (61.6%) and was significantly higher in anakinra-treated patients than in the controls (75.0 versus 48.2%, p = 0.007). When stratified by continuous positive airway pressure support at baseline, anakinra-treated patients' survival was also significant compared with the controls (p = 0.008). Univariate analysis identified anakinra usage (odds ratio, 3.2; 95% confidence interval, 1.47-7.17) as a significant survival predictor. This was not supported by multivariate modeling. The rate of infectious-related adverse events was similar between groups. In conclusion, anakinra improved overall survival and invasive ventilation-free survival and was well tolerated in patients with ARDS associated with COVID-19.

PURPOSE: The aim of our study was to assess respiratory function at the time of clinical recovery and 6 weeks after discharge in patients surviving to COVID-19 pneumonia. METHODS: Our case series consisted of 13 patients with COVID-19 pneumonia. RESULTS: At the time of clinical recovery, FEV1 (2.07 ± 0.72 L) and FVC (2.25 ± 0.86 L) were lower compared to lower limit of normality (LLN) values (2.56 ± 0.53 L, p = 0.004, and 3.31 ± 0.65 L, p < 0.001, respectively), while FEV1/FVC (0.94 ± 0.07) was higher compared to upper limit of normality (ULN) values (0.89 ± 0.01, p = 0.029). After 6 weeks pulmonary function improved but FVC was still lower than ULN (2.87 ± 0.81, p = 0.014). CONCLUSION: These findings suggest that COVID-19 pneumonia may result in clinically relevant alterations in pulmonary function tests, with a mainly restrictive pattern.
