Background Severity of illness in COVID-19 is consistently lower in women. Focus on sex as a biologic factor may suggest a potential therapeutic intervention for this disease. We assessed whether adding progesterone to standard of care would improve clinical outcomes of hospitalized men with moderate to severe COVID-19. Research Question Does short-term subcutaneous administration of progesterone safely improve clinical outcome in hypoxemic men hospitalized with COVID-19? Study Design and Methods We conducted a pilot, randomized, open-label, controlled trial of subcutaneous progesterone in men hospitalized with confirmed moderate to severe COVID-19. Patients were randomly assigned to receive standard of care (SOC) plus progesterone (100 mg subcutaneously twice daily for up to five days) or SOC alone. In addition to assessment of safety, the primary outcome was change in clinical status at day 7. Length of hospital stay and number of days on supplemental oxygen were key secondary outcomes. Results Forty-two patients were enrolled from April - August 2020; 22 were randomized to the control group and 20 to the progesterone group. Two patients from the progesterone group withdrew from the study prior to receiving progesterone. There was a 1.5-point overall improvement in median clinical status score on a seven-point ordinal scale from baseline to Day 7 in patients in the progesterone group as compared to controls (95%CI:0.0-2.0; P=0.024). There were no serious adverse events attributable to progesterone. Patients treated with progesterone required 3 fewer days of supplemental oxygen (median of 4.5 vs 7.5 days) and were hospitalized for 2.5 fewer days (median of 7.0 vs 9.5 days) as compared to controls. Interpretation Progesterone at a dose of 100 mg, twice daily by subcutaneous injection in addition to SOC may represent a safe and effective approach for treatment in hypoxemic men with moderate to severe COVID-19.

; on behalf of the RENEW Study Group * BACKGROUND: The Lung Volume Reduction Coil Treatment in Patients With Emphysema (RENEW) trial reported improvements in quality of life, pulmonary function, and exercise performance following endobronchial coil treatment. OBJECTIVES: The purpose of this post hoc analysis was to identify baseline predictors, including quantitative CT measures, that identify patients most likely to significantly benefit from endobronchial coil therapy. METHODS: Quantitative CT analysis by an independent radiology laboratory and a qualitative evaluation by five blinded experts of the baseline thoracic CT imaging were performed. Univariate and multivariate logistic regression analyses were performed to elucidate characteristics associated with clinical response. RESULTS: In total, 125 patients underwent coil treatment and had evaluable 12-month followup results. Of these, 78 patients received treatment of lobes with the highest emphysematous destruction determined by quantitative CT analysis (quantitative visual match [QVM]þ), and 47 received treatment in at least one lobe that was not the most destroyed (QVM-). From the 78 patients with QVMþ treatment, a subgroup of 50 patients (64%) was identified with baseline residual volume > 200% predicted, emphysema score > 20% low attenuation area, and absence of airway disease. In this subgroup, greater lobar residual volume reduction in the treated lobes was achieved, which was associated with significant mean AE SE improvement in FEV 1 (15.2 AE 3.1%), St. George's Respiratory Questionnaire (-12 AE 2 points), and residual volume (-0.57 AE 0.13 L). DISCUSSION: This post hoc analysis found that both significant hyperinflation (residual volume $ 200% predicted) and CT analysis are critical for patient selection and treatment planning for endobronchial coil therapy. Quantitative CT analysis is important to identify optimal lobar treatment and to exclude patients with insufficient emphysema (< 20% low attenuation area), whereas visual assessment identifies patients with signs of airway disease associated with worse outcomes.
Background and objective: The RENEW trial demonstrated that bronchoscopic lung volume reduction using endobronchial coils improves quality of life, pulmonary function and exercise performance. In this post hoc analysis of RENEW, we examine the mechanism of action of endobronchial coils that drives improvement in clinical outcomes. Methods: A total of 78 patients from the RENEW coiltreated group who were treated in one or both lobes that were deemed as the most destroyed were included in this retrospective analysis. Expiratory and inspiratory HRCT scans were used to assess lobar volume change from baseline to 12 months post coil treatment in treated and untreated lobes. Results: Reduction in lobar RV in treated lobes was significantly associated with favourable clinical improvement. Independent predictor of the change in RV and FEV 1 was the change in lobar RV reduction in the treated lobes and for change in 6MWD the absence of cardiac disease and the change in SGRQ, while the independent predictor of change in SGRQ was the change in 6MWD. Conclusion: Our results suggest that residual lobar volume reduction in treated lobes measured by QCT is the driving mechanism of action of endobronchial coils leading to positive clinical outcomes. However, the improvement in exercise capacity and quality of life seems to be affected by the presence of cardiac disease.

Problem:We evaluated eculizumab, a complement protein C5 inhibitor, for treatment of severe COVID-19 in pregnant and postpartum individuals. Method ofStudy: Protocol ECU-COV-401 (clinicaltrials.gov NCT04355494) is an open label, multicenter, Expanded Access Program (EAP), evaluating eculizumab for treatment of severe COVID-19. Participants enrolled at our center from August 2020 to February 2021. Hospitalized patients were eligible if they had severe COVID-19 with bilateral pulmonary infiltrates and oxygen requirement. Eculizumab was administered on day 1 (1200 mg IV) with additional doses if still hospitalized (1200 mg IV on Days 4 and 8; 900 mg IV on Days 15 and 22; optional doses on Days 12 and 18). The primary outcome was survival at Day 15. Secondary outcomes included survival at Day 29, need for mechanical ventilation, and duration of hospital stay. We evaluated pharmacokinetic and pharmacodynamic data, safety, and adverse outcomes. Results: Eight participants were enrolled at the Cedars-Sinai Medical Center, six during pregnancy (mean 30 ± 4.0 weeks) and two in the postpartum period. Baseline oxygen requirement ranged from 2 L/min nasal cannula to 12 L/min by non-rebreather mask. The median number of doses of eculizumab was 2 (range 1-3); the median This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.
