  Abstract

  Type III interferons have been touted as promising therapeutics in outpatients with coronavirus disease 2019 (COVID-19). We conducted a randomized, single-blind, placebo-controlled trial (NCT04331899) in 120 outpatients with mild to moderate COVID-19 to determine whether a single, 180 mcg subcutaneous dose of Peginterferon Lambda-1a (Lambda) within 72 hours of diagnosis could shorten the duration of viral shedding (primary endpoint) or symptoms (secondary endpoint). In both the 60 patients receiving Lambda and 60 receiving placebo, the median time to cessation of viral shedding was 7 days (hazard ratio [HR] = 0.81; 95% confidence interval [CI] 0.56 to 1.19). Symptoms resolved in 8 and 9 days in Lambda and placebo, respectively, and symptom duration did not differ significantly between groups (HR 0.94; 95% CI 0.64 to 1.39). Both Lambda and placebo were well-tolerated, though liver transaminase elevations were more common in the Lambda vs. placebo arm (15/60 vs 5/60; p = 0.027). In this study, a single dose of subcutaneous Peginterferon Lambda-1a neither shortened the duration of SARS-CoV-2 viral shedding nor improved symptoms in outpatients with uncomplicated COVID-19.

• Impact of Sepsis Mandates on Sepsis Care: Unintended Consequences. The Journal of infectious diseases Swenson, K. E., Winslow, D. L. 2020; 222 (Supplement_2): S166–S173

  Abstract

  The creation of dedicated sepsis guidelines and their broad dissemination over the past 2 decades have contributed to significant improvements in sepsis care. These successes have spurred the creation of bundled care mandates by major healthcare payers, such as the Center for Medicare and Medicaid Services. However, despite the likely benefits of guideline-directed sepsis bundles, mandated treatments in sepsis may lead to unintended consequences as the standard of care in sepsis improves. In particular, the heterogeneous spectrum of presentation and disease severity in sepsis, as well as the complexity surrounding the benefits of specific interventions in sepsis, argues for an individualized and titrated approach to interventions: an approach generally not afforded by care mandates. In this review, we review the risks and benefits of mandated care for sepsis, with particular emphasis on the potential adverse consequences of common bundle components such as early empiric antibiotics, weight-based fluid administration, and serum lactate monitoring. Unlike guideline-directed care, mandated care in sepsis precludes providers from tailoring treatments to heterogeneous clinical scenarios and may lead to unintended harms for individual patients.

N., Masur, H., Septimus, E. J., Sweeney, D. A., Strich, J. R., Winslow, D. L., Klompas, M. 2020

  Abstract

  The Centers for Medicare & Medicaid Services' Severe Sepsis and Septic Shock Early Management Bundle (SEP-1) measure has appropriately established sepsis as a national priority. However, the Infectious Diseases Society of America (IDSA and five additional endorsing societies) is concerned about SEP-1's potential to drive antibiotic overuse because it does not account for the high rate of sepsis overdiagnosis and encourages aggressive antibiotics for all patients with possible sepsis, regardless of the certainty of diagnosis or severity of illness. IDSA is also concerned that SEP-1's complex "time zero" definition is not evidence-based and is prone to inter-observer variation. In this position paper, IDSA outlines several recommendations aimed at reducing the risk of unintended consequences of SEP-1 while maintaining focus on its evidence-based elements. IDSA's core recommendation is to limit SEP-1 to septic shock, for which the evidence supporting the benefit of immediate antibiotics is greatest. Prompt empiric antibiotics are often appropriate for suspected sepsis without shock, but IDSA believes there is too much heterogeneity and difficulty defining this population, uncertainty about the presence of infection, and insufficient data on the necessity of immediate antibiotics to support a mandatory treatment standard for all patients in this category. IDSA believes guidance on managing possible sepsis without shock is more appropriate for guidelines that can delineate the strengths and limitations of supporting evidence and allow clinicians discretion in applying specific recommendations to individual patients. Removing sepsis without shock from SEP-1 will mitigate the risk of unnecessary antibiotic prescribing for noninfectious syndromes, simplify data abstraction, increase measure reliability, and focus attention on the population most likely to benefit from immediate empiric broad-spectrum antibiotics.

• Infectious Diseases Society of America (IDSA) POSITION STATEMENT: Why IDSA Did Not Endorse the Surviving Sepsis Campaign Guidelines CLINICAL INFECTIOUS DISEASES Kalil, A. C., Gilbert, D. N., Winslow, D. L., Masur, H., Klompas, M., IDSA Sepsis Task Force 2018; 66 (10): 1631–35

  Abstract

  IDSA did not endorse the 2016 Surviving Sepsis Campaign Guidelines despite being represented in the working group that drafted the guidelines document. Leadership from the IDSA, the Surviving Sepsis Campaign Guidelines, and the Society of Critical Care Medicine had numerous amicable discussions primarily regarding the bolded, rated guidelines recommendations. Our societies had different perspectives, however, regarding the interpretation of the major studies that informed the guidelines' recommendations, thus leading us to different conclusions and different perspectives on the recommendations. IDSA consequently elected not to endorse the guidelines. IDSA nonetheless hopes to be able to continue collaborating with the Surviving Sepsis Campaign and the Society of Critical Care Medicine to resolve our differences and to develop further strategies together to prevent sepsis and septic shock as well as reduce death and disability from these conditions both nationally and globally.

• Efavirenz Plasma Concentrations and Cytochrome 2B6 Polymorphisms ANNALS OF PHARMACOTHERAPY Lindfelt, T., O'Brien, J., Song, J. C., Patel, R., Winslow, D. L. 2010; 44 (10): 1572-1578

  Abstract

  Interpatient variability in efavirenz concentrations may be due to CYP2B6 genetic polymorphisms. Efavirenz concentration and pharmacogenomic data are scarce in Latino patients.To evaluate the difference in trough and midpoint efavirenz plasma concentrations between HIV-positive Latino and white patients. In addition, this study evaluated the association between efavirenz concentrations and CYP2B6 polymorphisms in Latino and white HIV-positive subjects.This pilot study included 10 Latinos and 10 whites. Two efavirenz blood concentrations were determined: a trough and a midpoint. CYP2B6 genetic polymorphisms were analyzed at the 516 (G to T) and 785 (A to G) codons. The Mann-Whitney test was used to determine whether efavirenz concentrations varied with ethnicity. The Kruskal-Wallis test was used to determine whether efavirenz concentrations varied with CYP2B6 genetic polymorphisms. Efavirenz concentrations were expressed as medians (minimum, maximum).Midpoint concentrations were 1.58 μg/mL (1.36, 6.02) and 3.14 μg/mL (1.74, 7.72) for whites and Latinos, respectively (p < 0.05). Trough concentrations did not vary as a function of ethnicity. Ten percent of Latinos and whites tested positive for homozygous variants of CYP2B6-516 and CYP2B6-785. One white subject tested positive for the homozygous variant of CYP2B6-1459. Trough concentrations for 516TT, 516GT, and 516GG (wild type) were 5.13 μg/mL (4.13, 6.12), 2.13 μg/mL (1.33, 3.37), and 1.44 μg/mL (0.59, 2.92), respectively (p < 0.05). Trough concentrations for 785GG, 785AG, and 785AA (wild type) were 5.12 μg/mL (4.13, 6.12), 1.98 μg/mL (1.33, 3.37), and 1.27 μg/mL (0.59, 2.92), respectively (p < 0.05). None of the patients took concomitant medications that impacted CYP2B6 metabolism.Trough efavirenz concentrations were significantly higher in patients with the 785 (A to G) and 516 (G to T) variants. Midpoint efavirenz concentrations in Latinos were significantly higher than those of whites.

• Efavirenz-induced hypersensitivity reaction manifesting in rash and hepatitis in a Latino male ANNALS OF PHARMACOTHERAPY Leung, J. M., O'Brien, J. G., Wong, H. K., Winslow, D. L. 2008; 42 (3): 425-429

  Abstract

  To report a case of hypersensitivity manifesting in a rash, fever, and life-threatening hepatitis in a patient initiated on efavirenz therapy.A 30-year-old Latino male newly diagnosed with HIV was started on efavirenz-based highly active antiretroviral therapy (HAART) using tenofovir 300 mg, emtricitabine 200 mg, and efavirenz 600 mg once daily. Eleven days after beginning therapy, he developed a hypersensitivity reaction manifesting in rash and fever preceding severe drug-induced hepatitis. Liver enzyme peak values were aspartate transaminase 3410 U/L and alanine transaminase 2132 U/L. Hepatitis resolved with discontinuation of the HAART. The patient was rechallenged with tenofovir and emtricitabine one year later; no adverse reactions occurred.The Naranjo probability scale demonstrated a probable relationship between this adverse reaction and efavirenz. A MEDLINE search (2004 to September 2007) revealed 2 cases of rash preceding hepatitis with the initiation of efavirenz. Both cases were in women; there were no prior reported cases of efavirenz hypersensitivity in men. Although the mechanism of this reaction is unknown, a few factors may have contributed to this reaction. The half-life and the auto-induction of efavirenz may explain the continued rise in liver enzymes and severe hepatitis that continued to occur once the drug was discontinued. Another cause that may have contributed is the metabolism of the medication. CYP2B6 is responsible for almost 90% of the clearance of efavirenz. Data from a recent pharmacokinetic study showed that efavirenz concentrations were higher in both black and Latino patients when compared with those of white patients. In addition, it is highly probable that this patient's liver function was impaired when transaminase levels peaked, resulting in decreased clearance of efavirenz.Although such a hypersensitivity reaction is rare, efavirenz is the most probable cause of the erythematous maculopapular rash and acute hepatitis in this patient. Monitoring of liver function in patients who present with a rash following initiation of efavirenz-based HAART is recommended. In addition, clinicians should exercise caution in patients presenting with rash, fever, and increased liver enzymes (> 3 times the upper limit of normal or patient baseline). It is strongly recommended that efavirenz therapy be withheld in such cases and reevaluated once liver enzyme levels stabilize.

• Wind, rain, flooding, and fear: Coordinating military public health in the aftermath of Hurricane Katrina CLINICAL INFECTIOUS DISEASES Winslow, D. L. 2005; 41 (12): 1759-1763

  Abstract

  On 29 August 2005, a category 4 hurricane struck the Gulf Coast of Mississippi and southeast Louisiana, resulting in widespread destruction caused by winds in excess of 190 km/h (120 miles/h), heavy rain, and flooding. Communication, electricity, and fresh water supplies were disrupted throughout the region, rendering much of the area uninhabitable. Despite tremendous obstacles, the US military spearheaded the eventually successful rescue, recovery, and relief operations. This article describes the challenges of protecting the health and safety of these personnel in the immediate aftermath of Hurricane Katrina.

• HIV-1 protease and reverse transcriptase mutation patterns responsible for discordances between genotypic drug resistance interpretation algorithms JAIDS-JOURNAL OF ACQUIRED IMMUNE DEFICIENCY SYNDROMES Ravela, J., Betts, B. J., Brun-Vezinet, F., Vandamme, A. M., Descamps, T., Van Laethem, K., Smith, K., Schapiro, J. M., Winslow, D. L., Reid, C., Shafer, R. W. 2003; 33 (1): 8-14

  Abstract

  Several rules-based algorithms have been developed to interpret results of HIV-1 genotypic resistance tests. To assess the concordance of these algorithms and to identify sequences causing interalgorithm discordances, we applied four publicly available algorithms to the sequences of isolates from 2,045 individuals in northern California. Drug resistance interpretations were classified as S for susceptible, I for intermediate, and R for resistant. Of 30,675 interpretations (2,045 sequences x 15 drugs), 4.4% were completely discordant, with at least one algorithm assigning an S and another an R; 29.2% were partially discordant, with at least one algorithm assigning an S and another an I, or at least one algorithm assigning an I and another an R; and 66.4% displayed complete concordance, with all four algorithms assigning the same interpretation. Discordances between nucleoside reverse transcriptase inhibitor interpretations usually resulted from several simple, frequently occurring mutational patterns. Discordances between protease inhibitor interpretations resulted from a larger number of more complex mutation patterns. Discordances between nonnucleoside reverse transcriptase inhibitor interpretations were uncommon and resulted from a small number of individual drug resistance mutations. Determining the clinical significance of these mutation patterns responsible for interalgorithm discordances will improve interalgorithm concordance and the accuracy of genotypic resistance interpretation.

• Accuracy of the TRUGENE HIV-1 genotyping kit JOURNAL OF CLINICAL MICROBIOLOGY Grant, R. M., Kuritzkes, D. R., JOHNSON, V. A., Mellors, J. W., Sullivan, J. L., Swanstrom, R., D'Aquila, R. T., van Gorder, M., Holodniy, M., Lloyd, R. M., Reid, C., Morgan, G. F., Winslow, D. L. 2003; 41 (4): 1586-1593

  Abstract

  Drug resistance and poor virological responses are associated with well-characterized mutations in the viral reading frames that encode the proteins that are targeted by currently available antiretroviral drugs. An integrated system was developed that includes target gene amplification, DNA sequencing chemistry (TRUGENE HIV-1 Genotyping Kit), and hardware and interpretative software (the OpenGene DNA Sequencing System) for detection of mutations in the human immunodeficiency virus type 1 (HIV-1) protease and reverse transcriptase sequences. The integrated system incorporates reverse transcription-PCR from extracted HIV-1 RNA, a coupled amplification and sequencing step (CLIP), polyacrylamide gel electrophoresis, semiautomated analysis of data, and generation of an interpretative report. To assess the accuracy and robustness of the assay system, 270 coded plasma specimens derived from nine patients were sent to six laboratories for blinded analysis. All specimens contained HIV-1 subtype B viruses. Results of 270 independent assays were compared to "gold standard" consensus sequences of the virus populations determined by sequence analysis of 16 to 20 clones of viral DNA amplicons derived from two independent PCRs using primers not used in the kit. The accuracy of the integrated system for nucleotide base identification was 98.7%, and the accuracy for codon identification at 54 sites associated with drug resistance was 97.6%. In a separate analysis of plasma spiked with infectious molecular clones, the assay reproducibly detected all 72 different drug resistance mutations that were evaluated. There were no significant differences in accuracy between laboratories, between technologists, between kit lots, or between days. This integrated assay system for the detection of HIV-1 drug resistance mutations has a high degree of accuracy and reproducibility in several laboratories.

• Clinical resistance patterns and responses to two sequential protease inhibitor regimens in saquinavir and reverse transcriptase inhibitor-experienced persons 5th Conference on Retroviruses and Opportunistic Infections Lawrence, J., Schapiro, J., Winters, M., Montoya, J., Zolopa, A., Pesano, R., Efron, B., Winslow, D., Merigan, T. C. UNIV CHICAGO PRESS. 1999: 1356–64

  Abstract

  The efficacy of sequential protease inhibitor therapy was studied in 16 human immunodeficiency virus (HIV) 1-infected persons in whom saquinavir with multiple nucleoside reverse transcriptase (RT) inhibitors (NRTI) had failed. Nelfinavir plus two NRTIs (new or continued) resulted in minimal (0.59 log RNA copies/mL) and transient (8 weeks) suppression of plasma HIV RNA levels. Rapid failure was surprisingly associated with baseline presence of protease gene mutation L90M (P=.04) in the absence of D30N and with RT mutations D67N (P<.01), K70R/S (P=.02), and K219Q/W/R/E (P<.01). Ten patients were subsequently switched to indinavir plus nevirapine and 2 NRTIs, resulting in a median 1.62 log reduction in plasma HIV RNA, with 3 patients maintaining 400 copies/mL for 24 weeks. These results suggest that nelfinavir may have limited utility after saquinavir failure, particularly without potent concomitant therapy. Combining an NRTI with a new protease inhibitor for rescue may improve response.
