Dalbavancin vs standard of care for Staphylococcus aureus bacteraemia in patients unable to receive outpatient parenteral antimicrobial therapy.

BACKGROUND: This study compared dalbavancin with standard of care (SOC) for patients with Staphylococcus aureus bacteraemia (SAB) who were unable to receive outpatient parenteral antimicrobial therapy (OPAT). METHODS: This retrospective cohort compared re-admission rates related to the index infection between patients treated with dalbavancin or SOC for SAB. Patients aged ≥18 years seen by the infectious diseases consult service who had received at least one dose of dalbavancin or at least 1 week of SOC parenteral antibacterials as directed therapy for SAB at the time of discharge were included. The SOC group consisted of patients transferred from the main hospital to one of the post-acute care facilities to complete parenteral antibacterials. The primary outcome was re-admission rate within 30 days of completion of therapy. Secondary outcomes included re-admission rate within 90 days of completion of therapy and adherence to the antibacterial regimen. RESULTS: Twenty-seven patients received dalbavancin and 27 patients received SOC. Baseline demographics were comparable between groups, although more patients in the SOC group had indwelling prostheses or hardware (4% vs 22%). The majority of SAB was caused by methicillin-susceptible S. aureus (56% vs 59%). Re-admission rates for the dalbavancin group were similar to those for the SOC group within 30 days (15% vs 22%; P=0.484) and 90 days (19% vs 22%; P=0.735) of completion of therapy. Adherence to the antibacterial regimen was significantly higher among patients treated with dalbavancin compared with SOC (85% vs 44%; P<0.001). CONCLUSIONS: Dalbavancin offers similar clinical outcomes to SOC for patients with SAB who are unable to receive OPAT.

Clinical Severity on Hospital Admission for COVID-19: An Analysis of Social Determinants of Health From an Early Hot Spot in the Southeastern U.S.

INTRODUCTION: Disparities in COVID-19 infection, illness severity, hospitalization, and death are often attributed to age and comorbidities, which fails to recognize the contribution of social, environmental, and financial factors on health. The purpose of this study was to examine relationships between social determinants of health (SDOH) and COVID-19 severity. METHODS: This multicenter retrospective study included adult patients hospitalized with COVID-19 in Southwest Georgia, U.S. The primary outcome was the severity of illness among patients on hospital admission for COVID-19. To characterize the effect of biological and genetic factors combined with SDOH on COVID-19, we used a multilevel analysis to examine patient-level and ZIP code-level data to determine the risk of COVID-19 illness severity at admission. RESULTS: Of 392 patients included, 65% presented with moderate or severe COVID-19 compared to 35% with critical disease. Compared to moderate or severe COVID-19, increasing levels of Charlson Comorbidity Index (OR 1.15, 95% CI 1.07-1.24), tobacco use (OR 1.85, 95% CI 1.10-3.11), and unemployment or retired versus employed (OR 1.91, 95% CI 1.04-3.50 and OR 2.17, 95% CI 1.17-4.02, respectively) were associated with increased odds of critical COVID-19 in bivariate models. In the multi-level model, ZIP codes with a higher percentage of Black or African American residents (OR 0.94, 95% CI 0.91-0.97) were associated with decreased odds of critical COVID-19. CONCLUSION: Differences in SDOH did not lead to significantly higher odds of presenting with severe COVID-19 when accounting for patient-level and ZIP code-level variables.

Missed opportunities to identify cryptococcosis in COVID-19 patients: a case report and literature review.

SARS-CoV-2 may activate both innate and adaptive immune responses ultimately leading to a dysregulated immune response prompting the use of immunomodulatory therapy. Although viral pneumonia increases the risk of invasive fungal infections, it remains unclear whether SARS-CoV-2 infection, immunomodulatory therapy, or a combination of both are responsible for the increased recognition of opportunistic infections in COVID-19 patients. Cases of cryptococcosis have previously been reported following treatment with corticosteroids, interleukin (IL)-6 inhibitors, and Janus kinase (JAK) inhibitors, for patients with autoimmune diseases, but their effect on the immunologic response in patients with COVID-19 remains unknown. Herein, we present the case of a patient with COVID-19 who received high-dose corticosteroids and was later found to have cryptococcosis despite no traditional risk factors. As our case and previous cases of cryptococcosis in patients with COVID-19 demonstrate, clinicians must be suspicious of cryptococcosis in COVID-19 patients who clinically deteriorate following treatment with immunomodulatory therapies.
