Compassionate Use of Remdesivir in Pregnant Women With Severe Coronavirus Disease 2019.

BACKGROUND: Remdesivir is efficacious for severe coronavirus disease 2019 (COVID-19) in adults, but data in pregnant women are limited. We describe outcomes in the first 86 pregnant women with severe COVID-19 who were treated with remdesivir. METHODS: The reported data span 21 March to 16 June 2020 for hospitalized pregnant women with polymerase chain reaction-confirmed severe acute respiratory syndrome coronavirus 2 infection and room air oxygen saturation ≤94% whose clinicians requested remdesivir through the compassionate use program. The intended remdesivir treatment course was 10 days (200 mg on day 1, followed by 100 mg for days 2-10, given intravenously). RESULTS: Nineteen of 86 women delivered before their first dose and were reclassified as immediate "postpartum" (median postpartum day 1 [range, 0-3]). At baseline, 40% of pregnant women (median gestational age, 28 weeks) required invasive ventilation, in contrast to 95% of postpartum women (median gestational age at delivery 30 weeks). By day 28 of follow-up, the level of oxygen requirement decreased in 96% and 89% of pregnant and postpartum women, respectively. Among pregnant women, 93% of those on mechanical ventilation were extubated, 93% recovered, and 90% were discharged. Among postpartum women, 89% were extubated, 89% recovered, and 84% were discharged. Remdesivir was well tolerated, with a low incidence of serious adverse events (AEs) (16%). Most AEs were related to pregnancy and underlying disease; most laboratory abnormalities were grade 1 or 2. There was 1 maternal death attributed to underlying disease and no neonatal deaths. CONCLUSIONS: Among 86 pregnant and postpartum women with severe COVID-19 who received compassionate-use remdesivir, recovery rates were high, with a low rate of serious AEs.

Do Positive Anaerobic Culture Results Affect Physicians' Clinical Management Decisions?

BACKGROUND: Aerobic and anaerobic cultures from body fluids, abscesses, and wounds are ordered routinely. Prior studies have shown that the results of anaerobic blood cultures do not frequently lead to changes in patient management. METHODS: We performed a retrospective chart review to determine whether positive results of anaerobic tissue and fluid cultures (excluding blood) affect physicians' treatment approaches. Of 3234 anaerobic cultures, 174 unique patient admissions had positive cultures and met inclusion criteria. RESULTS: Only 18% (n = 31) of patient charts with positive cultures had documented physician acknowledgment (90.3% of acknowledgments by infectious diseases physicians), with 9% (n = 15) leading to change in antibiotic regimens based on results. Seventy percent of all patients received initial empiric antibiotics active against anaerobes. Of the remaining 30% (inappropriate, unknown, or no empiric coverage), 1 regimen change was documented after culture results were known. CONCLUSIONS: Given the lack of management change based on results of anaerobic wound cultures, the value of routine anaerobic culturing is of questionable utility.

Diagnosis of Extrapulmonary Legionellosis in Allogeneic Hematopoietic Cell Transplant Recipients by Direct 16S Ribosomal Ribonucleic Acid Sequencing and Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry.

Identifying extrapulmonary legionellosis is difficult due to the lack of clinical suspicion and limitations of conventional microbiologic methods. We present a case series of hematopoietic cell transplant recipients with extrapulmonary legionellosis diagnosed via molecular diagnostics: 16S ribosomal ribonucleic acid gene Sanger sequencing and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.
