Antimicrobial Stewardship Pearl
- A recent consensus statement from the Society for Healthcare Epidemiology of America provides recommendations for hospitals and healthcare personnel to improve antimicrobial stewardship and antibiotic use during infectious disease public health emergencies such as outbreaks, epidemics, and pandemics. The statement encourages leveraging the expertise of Antimicrobial Stewardship Programs to limit inappropriate antibiotic prescribing practices by facilitating evidence-based care.
- This report summarizes all recommendations from CDC’s Advisory Committee on Immunization Practices (ACIP) for the use of lyophilized CVD 103-HgR vaccine (Vaxchora) in the US. CVD 103-HgR, a single-dose, live attenuated oral cholera vaccine derived from V. cholerae O1, is the only cholera vaccine licensed for use in the US (MMWR Recomm Rep 2022;71:1-8). PDF available here.
- Updated recommendations for the use of 15-valent pneumococcal conjugate vaccine (PCV15, Vaxneuvance) in US children (MMWR Morb Mortal Wkly Rep 2022;71:1174). PDF available here.
Pentavalent Antimonials for Leishmaniasis
- Stibogluconate sodium (Pentostam) has been discontinued by GSK worldwide and is no longer available from CDC.
- Meglumine antimoniate (Glucantime) is available from Sanofi after obtaining an IND from FDA. Click here for instructions.
CDC Discontinues Distribution of Artesunate
- CDC has discontinued distribution of intravenous artesunate for treatment of severe malaria in the US. Commercial IV artesunate is available in adequate supply from major drug distributors. Click here for more details.
ZeNix Trial for Highly Drug-Resistant Tuberculosis
- The six-month oral regimen of bedaquiline-pretomanid-linezolid has 90% efficacy against highly drug-resistant tuberculosis. Unfortunately, peripheral neuropathy and myelosuppression associated wtih linezolid (1200 mg po once daily) in this regimen are problematic. In the ZeNix trial, different doses and durations of linezolid were investigated for efficacy and safety. The regimen employing linezolid 600 mg once daily for 26 weeks appeared to have the most favorable risk-benefit profile (N Engl J Med 2022;387:810).
ART in Pregnancy
- A dolutegravir (DTG)-based regimen is preferred as first-line antiretroviral therapy (ART) in pregnant persons infected with HIV. However, safety and efficacy data for other INSTI-based, PI-based, and NNRTI-based regimens compared to DTG-based ART are lacking. In this US multisite cohort study, DTG-based ART was superior to regimens based on atazanavir/r, raltegravir, and elvitegravir/cobicistat, and similar to regimens based on darunavir/r and rilpivirine, in achieving viral suppression at delivery. No clear differences in risk of adverse birth outcomes with DTG-based ART compared to other ART regimens were observed (N Engl J Med 2022;387:799).
Ceftaroline and CNS Infection
Ceftaroline is a possible option for CNS infection due to MRSA, but supportive data are scant. In a population pharmacokinetic model, an inverse relationship was found between CSF glucose concentration and intercompartmental clearance into the CSF. Model simulations showed a median ceftaroline penetration into the CSF of 4% in the group with uninflamed meninges, 19% in the group with mildly inflamed meninges, and 62% in the group with inflamed meninges. These differences in CSF exposure result in marked differences in probability of target attainment for specific microbes. The authors suggest that a dose of 600 mg IV q8h should be further evaluated for treatment of CNS infection (Antimicrob Agents Chemother 2022;66: e0074122).
