RESUMEN
BACKGROUND: Hematopoietic cell transplant (HCT) or chimeric antigen receptor (CAR) T-cell therapy recipients have high morbidity from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. There are limited data on outcomes from SARS-CoV-2 infection shortly before cellular therapy and uncertainty whether to delay therapy. METHODS: We conducted a retrospective cohort study of patients with SARS-CoV-2 infection within 90 days before HCT or CAR-T-cell therapy between January 2020 and November 2022. We characterized the kinetics of SARS-CoV-2 detection, clinical outcomes following cellular therapy, and impact on delays in cellular therapy. RESULTS: We identified 37 patients (n = 15 allogeneic HCT, n = 11 autologous HCT, n = 11 CAR-T-cell therapy) with SARS-CoV-2 infections within 90 days of cellular therapy. Most infections (73%) occurred between March and November 2022, when Omicron strains were prevalent. Most patients had asymptomatic (27%) or mild (68%) coronavirus disease 2019 (COVID-19). SARS-CoV-2 positivity lasted a median of 20.0 days (interquartile range, 12.5-26.25 days). The median time from first positive SARS-CoV-2 test to cellular therapy was 45 days (interquartile range, 37.75-70 days); 1 patient tested positive on the day of infusion. After cellular therapy, no patients had recrudescent SARS-CoV-2 infection or COVID-19-related complications. Cellular therapy delays related to SARS-CoV-2 infection occurred in 70% of patients for a median of 37 days. Delays were more common after allogeneic (73%) and autologous (91%) HCT compared to CAR-T-cell therapy (45%). CONCLUSIONS: Patients with asymptomatic or mild COVID-19 may not require prolonged delays in cellular therapy in the context of contemporary circulating variants and availability of antiviral therapies.

As the infectious disease (ID) workforce encounters increasing demand for services with fewer physicians entering the field, advanced practice providers (APPs) in infectious disease offer a unique ability to enhance high-quality patient care. However, little is known about their incorporation into ID, their utilization in immunocompromised settings, or their future use. This article reviews currently known data on APPs in ID including how some groups have used APPs and provides a framework for thoughtful, deliberate steps to incorporate APPs into the ID medical team, including transplant infectious disease. Highlighted specifically are education and mentorship opportunities with ideas for curriculum development and onboarding approaches. Strategic steps must be taken for APP inclusion as the medical landscape continues to change, patient complexity increases, and the ID team of the future takes shape.

BACKGROUND: There are limited data on clinical outcomes associated with the use of bebtelovimab for the treatment of coronavirus disease 2019 (COVID-19) among cancer patients. We aimed to define the clinical characteristics and outcomes among patients receiving bebtelovimab as part of the COVID-19 therapeutics program at our cancer center. METHODS: This is a retrospective cohort study of immunosuppressed adult patients who received bebtelovimab at Fred Hutchinson Cancer Center between March 2022, and November 2022. We reviewed medical records to capture the date of the first positive COVID-19 test, clinical characteristics, outcomes, and follow-up COVID-19 testing for 60 days after the first positive. Persistent infection was defined as a positive test beyond day 30; these patients were reviewed beyond day 60. RESULTS: Among 93 patients who received bebtelovimab, 64 (69%) had hematologic malignancy. Sixty-nine (74%) patients received bebtelovimab within 2 days after diagnosis. Two (2%) patients were hospitalized, none required ICU care, and one patient died on day 52; although it is unknown if death was directly related to COVID-19. Ten (11%) patients had persistent COVID-19 infection; of these, four received additional COVID-19 therapy with either nirmatrelvir/ritonavir or remdesivir, and five out of six patients with sequencing data available had spike protein mutations associated with bebtelovimab resistance. CONCLUSION: A coordinated systems-based approach led to prompt initiation of bebtelovimab within two days of testing positive in most patients. We observed few hospitalizations or deaths. Persistent infection was noted in 11% of patients with four requiring additional therapies, highlighting a need for novel strategies to manage immunosuppressed patients.

RESUMEN
Persistent symptomatic coronavirus disease 2019 (COVID-19) is a distinct clinical entity among patients with hematologic cancer and/or profound immunosuppression. The optimal medical management is unknown. We describe 2 patients who had symptomatic COVID-19 for almost 6 months and were successfully treated in the ambulatory setting with extended courses of nirmatrelvir-ritonavir.
RESUMEN
A patient with B-cell acute lymphoblastic leukemia (ALL) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had persistent, progressive pneumonia with viremia after 5 months of infection despite monoclonal antibodies, intravenous (IV) remdesivir and prolonged oral steroids. Twenty days of nirmatrelvir/ritonavir and 10 days of IV remdesivir led to full recovery.

RESUMEN
Pneumonia due to cytomegalovirus and herpes simplex virus-1 caused substantial morbidity after hematopoietic cell transplantation before the institution of preventative approaches. End-organ disease from herpesviruses is poorly described after chimeric antigen receptor-modified T-cell immunotherapy. We report 2 cases of cytomegalovirus pneumonia and 1 case of herpes simplex virus-1 gingivostomatitis, esophagitis, and pneumonia after chimeric antigen receptor-modified T-cell immunotherapy for the treatment of hematologic malignancies.

BACKGROUND: High morbidity and mortality have been observed in patients with cancer and coronavirus disease 2019 (COVID-19); however, there are limited data on antimicrobial use, coinfections, and viral shedding. METHODS: We conducted a retrospective cohort study of adult patients at the Seattle Cancer Care Alliance diagnosed with COVID-19 between February 28, 2020 and June 15, 2020 to characterize antimicrobial use, coinfections, viral shedding, and outcomes within 30 days after diagnosis. Cycle threshold values were used as a proxy for viral load. We determined viral clearance, defined as 2 consecutive negative results using severe acute respiratory syndrome coronavirus 2 reverse-transcription polymerase chain reaction results through July 30, 2020. RESULTS: Seventy-one patients were included with a median age of 61 years; 59% had a solid tumor. Only 3 patients had documented respiratory bacterial coinfection. Empiric antibiotics for pneumonia were prescribed more frequently early in the study period (February 29-March 28, 2020; 12/34) compared to the later period (March 29-June 15, 2020; 2/36) (Pâ =â .002). The median number of days from symptom onset to viral clearance was 37 days with viral load rapidly declining in the first 7-10 days after symptom onset. Within 30 days of diagnosis, 29 (41%) patients were hospitalized and 12 (17%) died. Each additional comorbidity was associated with 45% lower odds of days alive and out of hospital in the month following diagnosis in adjusted models. CONCLUSIONS: Patients at a cancer center, particularly those with multiple comorbidities, are at increased risk of poor outcomes from COVID-19. Prolonged viral shedding is frequently observed among cancer patients, and its implications on transmission and treatment strategies warrant further study.
RESUMEN
Patients with hematologic malignancy or bone marrow failure are typically required to achieve radiographic improvement or stabilization of invasive fungal infection (IFI) before hematopoietic cell transplantation (HCT) owing to a concern for progression before engraftment. Refractory IFI with a mixture of improvement and progression on serial imaging (ie, mixed response) poses a clinical dilemma, because a delay in HCT may allow for a hematologic relapse or other complications. Furthermore, HCT itself may yield the immune reconstitution necessary for clearance of infection. We sought to describe the characteristics and outcomes of patients who underwent HCT with mixed response IFI. We performed a chart review of all patients who underwent HCT between 2014 and 2020 in whom imaging within 6 weeks before HCT indicated a mixed response to treatment of a diagnosed IFI. Fourteen patients had evidence of a mixed response in low-to-moderate burden of diagnosed IFI by imaging before HCT, including 9 with pulmonary aspergillosis, 2 with hepatosplenic candidiasis (1 also with aspergillosis), and 4 with pulmonary nodules of presumed fungal etiology. Five had refractory severe neutropenia at evaluation for HCT (median, 95 days). All 14 patients showed radiographic stability or improvement in imaging following engraftment; no IFI-related surgeries were required, and no IFI-related deaths occurred. For patients without relapse who underwent HCT more than 1 year earlier, 7 of 8 (88%) were alive at 1 year. Our findings suggest that low-to-moderate burden IFI with mixed response is unlikely to progress on appropriate therapy before engraftment during allogeneic HCT.

Background: Shortages of infectious disease (ID) physicians is an identified workforce problem. The COVID-19 pandemic has exacerbated this care gap, leaving many communities without access to an ID physician. More advanced practice providers (APPs), specifically nurse practitioners and physician assistants, work as healthcare extenders, yet are not well described in ID. Purpose: Evaluate collaboration between ID physicians and APPs, and potential barriers to utilization of APPs. Methods: Anonymous and voluntary surveys; one for physicians, another for APPs. We collected experience, practice setting, familiarity regarding APPs in ID, use of APPs, and perceived barriers/concerns for utilization of APPs. Discussion: Nationwide, 218 ID physicians and 93 APPs in ID responded. 71% (155) of ID physicians use APPs. Of APPs, 53% (49) had > 5 years ID experience. Responses highlighted opportunities for dedicated ID education, collaboration, and clarification of practice scope. Conclusion: APPs are an experienced group who provide ID care, working alongside physicians to meet ID workforce needs.
RESUMEN
PURPOSE: Some fetuses with sacrococcygeal teratoma (SCT) develop hydrops, but there is no consensus on an appropriate prognostic marker for poor prognosis. The purpose of this study is to establish predictors of poor prognosis in fetuses with SCT. METHODS: A retrospective review of patients with prenatally diagnosed SCT from 1986 to 2011 was performed. Patients with outcome data and ultrasound exams before 32 weeks gestational age (GA) were included (n=37). Tumor volume-to-fetal weight ratio (TFR) and tumor morphology were assessed as sonographic predictors of poor prognosis. RESULTS: Twelve patients (32%) had good prognosis, and twenty-five patients (68%) had poor prognosis. All patients with poor prognosis had a morphology score ≥ 3, which is a significant predictor of poor prognosis (p <0.0001). TFR was assessed, and a receiver operating characteristic (ROC) analysis identified a cutoff value of 0.12 before 24 weeks GA and 0.11 before 32 weeks GA as predictors for poor prognosis. TFR is a significant predictor of poor prognosis (p<0.0001). CONCLUSIONS: Patients with cystic SCT all had good prognosis. TFR >0.12 was validated as a sonographic predictor of poor prognosis. TFR and tumor morphology can be used to counsel expectant families with prenatally diagnosed SCT regarding prognosis.
