Multicenter Study Observational Study
SARS-CoV-2 Detection on Bronchoalveolar Lavage: An Italian Multicenter experience.
Bronchoscopy with bronchoalveolar lavage (BAL) during the SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) pandemic should be reserved to a limited number of clinical indications. The yield of BAL for the diagnosis of suspected or confirmed pulmonary SARS-CoV-2 infection is still unknown. ⋯ In our centers, the rate of detection of SARS-CoV-2 on BAL in patients with suspected infection was 37.2%. The agreement of BAL with nasopharyngeal swabs was high; CT alterations could predict the pretest probability of SARS-CoV-2 infection, but suspicion of viral infection should be always considered.

Practice Guideline
Position Paper for the State-of-the-Art Application of Respiratory Support in Patients with COVID-19.
Against the background of the pandemic caused by infection with the SARS-CoV-2 virus, the German Respiratory Society has appointed experts to develop therapy strategies for COVID-19 patients with acute respiratory failure (ARF). Here we present key position statements including observations about the pathophysiology of (ARF). In terms of the pathophysiology of pulmonary infection with SARS-CoV-2, COVID-19 can be divided into 3 phases. ⋯ Under CPAP/NIV, a patient can deteriorate rapidly. For this reason, continuous monitoring and readiness for intubation are to be ensured at all times. If the ARF progresses under CPAP/NIV, intubation should be implemented without delay in patients who do not have a "do not intubate" order.

Observational Study
Characteristics of Pulmonary Auscultation in Patients with 2019 Novel Coronavirus in China.
Effective auscultations are often hard to implement in isolation wards. To date, little is known about the characteristics of pulmonary auscultation in novel coronavirus (COVID-19) pneumonia. ⋯ The abnormal breath sounds in COVID-19 pneumonia had some consistent distributive characteristics and to some extent correlated with the radiologic features. Such evidence suggests that electronic auscultation is useful to aid diagnosis and timely management of the disease. Further studies are indicated to validate the accuracy and potential clinical benefit of auscultation in detecting pulmonary abnormalities in COVID-19 infection.

Coronavirus disease 2019 (COVID-19) has become a global emerging infectious disease. ⋯ Patients with severe forms of this disease were more likely to get positive results. Age and organ dysfunction were associated with a greater risk of death.

Observational Study
Use of Intravenous Immunoglobulin (Prevagen or Octagam) for the Treatment of COVID-19: Retrospective Case Series.
Treatment with immunomodulators, such as intravenous immunoglobulin (IVIG), may attenuate inflammatory responses observed in the severe stages of acute respiratory distress syndrome (ARDS) caused by coronavirus disease 19 (COVID-19). We retrospectively evaluated the clinical courses of 12 COVID-19 patients who received IVIG at various stages of their illness, including within the first 72 h of clinical presentation, after initiation of mechanical ventilation, and after prolonged ventilation and ICU stay. The patients included 9 men and 3 women with a median age of 50 years (range 23-74), median Charlson Comorbidity Score of 2 (range 0-7), and median Acute Physiology and Chronic Health Evaluation Score of 13 (range 5-33) at the time of IVIG. ⋯ Despite very high illness severity scores, all patients survived hospital discharge. No thrombotic events occurred and IVIG was well tolerated, despite most cases demonstrating very elevated D-dimer suggestive of active intravascular fibrinolysis. We believe that IVIG warrants immediate clinical trial evaluation in COVID-19 to confirm its role as a mainstay treatment of moderate to severe COVID-19 infection as a means to reduce hospital stay and utilization of ICU resources, including mechanical ventilation, and potentially reduce mortality.
