Detailed Description
Sepsis is recognized nowadays as one of the major causes of global morbidity and mortality. One analysis of global data revealed that 49 million of new cases are admitted to hospitals every year and that 11 million of the patients die. Sepsis is the life-threatening organ dysfunction which develops due to the dysregulated response of the host to an infection; mortality is ranging between 20 and 25%. The most common infections leading to sepsis are infections of the lower respiratory tract (LRTIs) mainly community-acquired pneumonia (CAP).
Numerous attempts have been done the last decades to decrease the substantial mortality of sepsis. Standard-of-care (SoC) therapy for sepsis is framed by the Surviving Sepsis Campaign (SSC) guidelines which are published every four years since 2004 (last publication 2021). The backbone of these guidelines is the early administration of intravenous antibiotics and fluids. In all editions of the SSC guidelines "early" means less than one hour from sepsis recognition. The experts recognize that the secret to decrease mortality is to intervene early before the dysregulated host response to the infection becomes exaggerated and impossible to withhold. The experts state that for every hour of delay in intervention the odds for survival decrease by relative 7.6%. Then the real ambiguity moves on how the initiation of the sepsis process can be recognized earlier than clinical deterioration appears.
The only way to achieve our current strategy is to implement a strategy linking the increase of a biomarker to an early intervention. This biomarker can be either a measured circulating protein or a bioscore. An example of how this strategy works is the biomarker-guided treatment of early COVID-19 (coronavirus disease 2019) recently approved by the European Medicines Agency (EMA). The biomarker suPAR (soluble urokinase plasminogen activator receptor) was used as a tool to recognize the patient at risk for severe respiratory failure and guided the start of the drug anakinra. This led to an overall 64% clinical benefit so as to become the first early precision intervention approved for infections by the EMA. The registered cut-off of suPAR which guides early intervention is 6 ng/ml or more.
The suPAR assay is not commercially available in the United States. However, all enrolled patients in SAVE-MORE trial were required to have a plasma soluble urokinase plasminogen activator receptor (suPAR) level ≥ 6 ng/mL. SAVE-MORE was double-blind, randomized controlled trial evaluated the efficacy and safety of anakinra, an IL-1α/β inhibitor, in 594 patients with COVID-19 at risk of progressing to respiratory failure as identified by plasma suPAR ≥6 ng ml-1, 85.9% (n = 510) of whom were receiving dexamethasone. In order to identify a comparable population as was studied in the SAVE-MORE trial, an alternative patient identification method was developed by the Food and Drug Administration (FDA) of the United States to select patients most likely to have suPAR ≥ 6 ng/mL based on commonly measured patient characteristics (Appendix I). This score contains eight clinical variable and patients meeting at least 3 of the variables should receive early anakinra treatment. Patients meeting at least three of the following eight criteria are considered likely to have suPAR ≥ 6 ng/mL at baseline: i) age 75 years or more; ii) need for oxygen supplementation; iii) current/previous smoking status; iv) Sequential Organ Failure Assessment (SOFA) score 3 or more; v) neutrophil-to-lymphocyte ratio (NLR) 7 or more; vi) blood hemoglobin 10.5 g/dL or less; vii) medical history of ischemic stroke; and viii) blood urea 50 mg/dL or more and/or medical history of renal disease. According to the SmPC, suPAR is a biomarker is used at the Emergency Department (ED) for the triage of patients for early discharge home or not; levels exceeding 6ng/ml advise for hosptialization.
With this precision-embedded approach adjunctive treatments may attenuate the exaggerated response of the host and improve outcomes. Macrolides are a unique class of drugs that combine both antibiotic and anti-inflammatory properties. Several meta-analyses have proven that addition of a macrolide to treatment decreases mortality by community-acquired pneumonia (CAP). However, the mortality benefit from macrolides treatment is coming from meta-analyses and no randomized clinical trial (RCT) has been published so far to demonstrate such a benefit. This is also heavily criticized in the recently published guidelines by the European Society of Intensive Care with the European Society of Clinical Microbiology and Infections Diseases (ESCMID) for the management of severe CAP where the recommendation for the co-administration of macrolides to β-lactams is characterized as low-quality evidence.
The only available RCT testing the value of early intervention with macrolides in patients with community-acquired pneumonia (CAP) is ACCESS (A randomized clinical trial of oral Clarithromycin in Community-acquired pneumonia to attenuatE inflammatory responseS and improve outcomeS) (EudraCT number 2020-004452-15; ClinicalTrials.gov NCT04724044). The inclusion criteria of the ACCESS trial have the characteristics of precision therapy i.e. participants were adults with CAP, meeting at least two of the criteria of the systemic inflammatory response syndrome, with SOFA (sequential organ failure assessment) score 2 or more and circulating procalcitonin 0.25 ng/ml or more. ACCESS had a composite primary endpoint pointing towards an early anti-inflammatory clinical benefit of clarithromycin. Patients achieving the endpoint should meet both two conditions A and B by day 4 since start of the study drug: condition A defined as at least 50% decrease of the respiratory symptoms score (RSS); and condition B defined as at least 30% decrease of the baseline SOFA score and/or favorable PCT kinetics (defined as at least 80% decrease of the baseline PCT or PCT less than 0.25 ng/ml). The study succeeded in the primary endpoint since this was met in 38.3% of patients randomized to the SoC + placebo group and in 67.9% of patients randomized to the SoC + clarithromycin group (p<0.0001). The ACCESS study also showed remarkable efficacy in all secondary endpoints and mainly to those endpoints pointing towards prevention of sepsis progression:
11.30% of patients treated with SoC and placebo progressed into sepsis during the 28-day follow-up compared to only 2.25% of patients treated with oral clarithromycin and placebo (hazard ratio 0.19; p: 0.009) 27.8% of patients treated with SoC and placebo developed a new sepsis episode during the 28-day follow-up compared to only 14.8% of patients treated with oral clarithromycin and placebo (hazard ratio 0.48; p: 0.009); and 65.4% of patients treated with SoC and placebo were discharged from hospital alive compared to 78.4% of patients treated with oral clarithromycin and placebo (hazard ratio 1.38; p: 0.027) Post-hoc analysis showed that 87.4% of study participants were meeting at least 3 of the FDA clinical score making the participants at high likelihood for suPAR 6 ng/ml or more. This means that use of suPAR can discriminate early patients with CAP who are at high likelihood to receive benefit towards prevention of progression into sepsis and organ dysfunction through early start of clarithromycin treatment.
Data from the ACCESS study also showed a significant effect of clarithromycin treatment on modulation of immune dysregulation taking place in CAP by day 4 when the primary endpoint was met. These data points towards improvement of the function of circulating monocytes towards better production of TNFα (tumour necrosis factor-alpha) after stimulation, decrease of circulating interleukin (IL)-10 and improvement of the IL-8/IL-10 ratio.
