Multifaceted highly targeted sequential multidrug treatment of early ambulatory high-risk SARS-CoV-2 infection (COVID-19).

The SARS-CoV-2 virus spreading across the world has led to surges of COVID-19 illness, hospitalizations, and death. The complex and multifaceted pathophysiology of life-threatening COVID-19 illness including viral mediated organ damage, cytokine storm, and thrombosis warrants early interventions to address all components of the devastating illness. In countries where therapeutic nihilism is prevalent, patients endure escalating symptoms and without early treatment can succumb to delayed in-hospital care and death. Prompt early initiation of sequenced multidrug therapy (SMDT) is a widely and currently available solution to stem the tide of hospitalizations and death. A multipronged therapeutic approach includes 1) adjuvant nutraceuticals, 2) combination intracellular anti-infective therapy, 3) inhaled/oral corticosteroids, 4) antiplatelet agents/anticoagulants, 5) supportive care including supplemental oxygen, monitoring, and telemedicine. Randomized trials of individual, novel oral therapies have not delivered tools for physicians to combat the pandemic in practice. No single therapeutic option thus far has been entirely effective and therefore a combination is required at this time. An urgent immediate pivot from single drug to SMDT regimens should be employed as a critical strategy to deal with the large numbers of acute COVID-19 patients with the aim of reducing the intensity and duration of symptoms and avoiding hospitalization and death.

Retrospective evaluation of antithrombin III supplementation in neonates and infants receiving enoxaparin for treatment of thrombosis.

BACKGROUND: Thromboembolic events are occurring at increasing rates in neonates and infants. At Children's Mercy Hospitals and Clinics, antithrombin III (AT3) concentrates are often used in combination with enoxaparin to supplement physiologically low AT3 levels. Theoretically, AT3 enhances the anticoagulant activity of enoxaparin and results in decreased time to therapeutic anti-Xa levels. No data exist on use of AT3 for this indication. PROCEDURE: This retrospective study compared time to therapeutic anti-Xa levels in patients <1 year of age receiving enoxaparin with AT3 (Group 1) and without AT3 (Group 2) for treatment of thrombosis. Primary objective was to compare time to therapeutic anti-Xa levels (0.5-1 U/ml) between groups. Secondary objectives included comparison of the initial and therapeutic dose of enoxaparin, enoxaparin dose changes, AT3 supplementation, and level monitoring. Bleeding events and cost were also evaluated. Statistical tests included Schuirmann's two one-sided tests for equivalence and general linear models/logistic regression for independent effects of age, critical illness, and timing of AT3. RESULTS: Mean time to therapeutic anti-Xa levels were not equivalent between Groups 1 and 2 (80.7 vs. 65.2 hours; P = 0.28). Initial enoxaparin dose and number of dose changes were equivalent. Group 1 required higher doses of enoxaparin to achieve therapeutic anti-Xa levels. Age, critical illness, and timing of AT3 had no effect on time to therapeutic anti-Xa levels. Bleeding events were not equivalent between Groups 1 and 2 (14.3% vs. 3.9%; P = 0.55). CONCLUSION: Supplementation with AT3 did not decrease time to therapeutic anti-Xa levels, added significant cost, and was associated with increased bleeding events.

Caregiver survey results related to handling of oral chemotherapy for pediatric patients with acute lymphoblastic leukemia.

BACKGROUND: Oral chemotherapy is commonly administered in the home; however, there may be harmful effects on healthy individuals who handle these medications. Caregivers of pediatric patients were surveyed to establish educational needs for safe handling of oral chemotherapy agents. METHODS: An 11-question self-report survey was developed to characterize handling practices for patients in maintenance therapy for acute lymphoblastic leukemia related to caregiver education, use of protective gear, preparation, and disposal of oral chemotherapy agents. RESULTS: Fifty questionnaires were collected. Seventy-two percent of responders reported receiving instruction on safe handling of oral chemotherapy. Ninety percent of responders reported that they did not utilize protective gear during preparation of oral chemotherapy. Although tablet crushers were designated for use with oral chemotherapy by 61% of responders, 22% used the same device to crush other nonchemotherapy medications. The majority of responders disposed of medication waste with regular garbage or poured the remainder down the sink. CONCLUSIONS: Caregiver survey responses demonstrated that personal safeguards were not routinely utilized by pediatric caregivers while handling oral chemotherapy. Future educational efforts should be directed to improve caregiver understanding related to the use of protective equipment, designation of supplies for use with chemotherapy agents, and safe disposal.
