Enterococci have evolved resistance mechanisms to protect their cell envelopes against bacteriocins and host cationic antimicrobial peptides (CAMPs) produced in the gastrointestinal environment. Activation of the membrane stress response has also been tied to resistance to the lipopeptide antibiotic daptomycin. However, the actual effectors mediating resistance have not been elucidated. Here, we show that the MadRS (formerly YxdJK) membrane antimicrobial peptide defense system controls a network of genes, including a previously uncharacterized 3-gene operon (madEFG) that protects the Enterococcus faecalis cell envelope from antimicrobial peptides. Constitutive activation of the system confers protection against CAMPs and daptomycin in the absence of …

Hemophagocytic Lymphohistiocytosis Due To Ehrlichiosis: A Case Series, Ajay Iyer, Mattias D'Anna, Shruti Verma, Thomas Pritchard, Vladimir Begilman, Himal Bajracharya, Kaveh Naemi

HCA Healthcare Journal of Medicine

Background

Hemophagocytic lymphohistiocytosis (HLH) is an immunologic syndrome characterized by excessive inflammation and tissue injury due to uncontrolled activation of the phagocytic system. The underlying mechanism is a lack of downregulation of activated macrophages and lymphocytes by natural killer and T cells. Unfortunately, the diagnosis is often delayed or missed due to the rarity of the disease, decreased awareness, and clinical picture variability. Ehrlichiosis is becoming a more prevalent tick-borne illness in endemic regions and a relatively uncommon but increasingly considered cause of HLH.

Case Presentation

We describe the cases of 2 patients diagnosed with secondary HLH as per the …

Background: Upregulation of IL-6 has been associated with worse prognosis in COVID-19 patients. Impact on IL-6 signalling has mostly been limited to clinical outcomes in IL-6 receptor antagonist trials. Methods: We performed a phase 2, randomised, double-blind, placebo-controlled trial (NCT04380961) of US-based hospitalised adults (< 85 years) with laboratory-confirmed SARS-CoV-2 infection and severe (low levels of supplemental oxygen) or critical disease (high levels of oxygen supplementation). Patients received sirukumab 5 mg/kg or placebo single dose IV on Day 1 plus standard of care. The primary endpoint was time to sustained clinical improvement up to Day 28 based on an ordinal scale. Secondary endpoints included clinical improvement, all-cause mortality, and safety. Following an interim analysis, the protocol was amended to only recruit patients with critical COVID-19. Findings: From May 2020 to March 2021, 209 patients were randomised; 112 had critical disease (72 sirukumab, 40 placebo) at baseline. Median time to sustained clinical improvement in critical patients was 17 and 23 days in the sirukumab and placebo groups (HR, 1∙1; 95% CI, 0∙66–1∙88; p > 0∙05). At Day 28, 59∙4% versus 55∙0% of patients achieved clinical improvement with sirukumab versus placebo and rates of all-cause mortality were 24∙6% versus 30∙0%, respectively. Rates of grade ≥ 3 adverse events were comparable between the sirukumab and placebo groups (25∙9% vs 32∙9%; all patients). Interpretation: In critical COVID-19 patients who received sirukumab, there …
