Background: In the ACCESS trial, the addition of clarithromycin to standard-of-care antibiotics (SoC) enhanced early clinical response and attenuated the inflammatory burden in adults with community-acquired pneumonia (CAP) requiring hospitalisation. A post-hoc analysis was performed to investigate the benefit in specific subgroups.

Methods: The primary endpoint comprised two conditions to be met during the first 72 h: ≥50% decrease in respiratory symptom severity score; and any of ≥30% decrease in sequential organ failure assessment score and favourable change in the kinetics of procalcitonin (PCT, defined as ≥80% PCT decrease or PCT <0.

Article Synopsis
  • Researchers classified sepsis into four clinical phenotypes using a simplified algorithm based on six admission parameters in a study involving 1498 patients, including those with bacterial sepsis and severe COVID-19.
  • The analysis found distinct characteristics and outcomes for the phenotypes, with Phenotype α showing low mortality risk and Phenotype δ having the highest mortality.
  • The study concludes that this phenotyping method is effective for predicting outcomes in both bacterial sepsis and severe COVID-19, suggesting it could have important prognostic applications.

Objectives: It is suggested that sepsis may be classified into four clinical phenotypes, using an algorithm employing 29 admission parameters. We applied a simplified phenotyping algorithm among patients with bacterial sepsis and severe COVID-19 and assessed characteristics and outcomes of the derived phenotypes.

Design: Retrospective analysis of data from prospective clinical studies.

We aimed to evaluate heparin-binding protein (HBP) as a marker of prognosis of unfavorable outcome in COVID-19 pneumonia. This was a post hoc analysis of the SAVE clinical trial investigating anakinra treatment, guided by suPAR (soluble urokinase plasminogen activator receptor) levels ≥6 ng/mL, for the prevention of severe respiratory failure in hospitalized patients with COVID-19 pneumonia. Baseline HBP plasma levels were measured in 534 patients by fluorescence dry quantitative immunoassay using the Jet-iStar 800 analyzer.

Article Synopsis
  • Researchers studied how different immune endotypes affect responses to anakinra treatment in patients with severe pneumonia caused by COVID-19 during the SAVE-MORE trial.
  • The study found that many patients transitioned between immune endotypes during treatment, with anakinra helping those with the adaptive endotype to maintain better outcomes.
  • Anakinra also reduced the risk of severe respiratory failure in patients with a coagulopathic endotype compared to placebo, indicating its potential benefits in managing sepsis-related conditions.

Article Synopsis
  • The study examines whether adding the macrolide antibiotic clarithromycin to β-lactam antibiotics can improve early clinical responses in hospitalized patients with community-acquired pneumonia, based on previous observational studies rather than randomized trials.
  • Conducted as a phase 3 double-blind randomized controlled trial in Greece, the research involved adult patients with severe pneumonia who were given either standard care plus a placebo or standard care plus clarithromycin for seven days.
  • The primary outcome measured included a significant improvement in respiratory symptoms and reduction in inflammatory response after 72 hours of treatment, with both groups being kept unaware of their allocated treatment for unbiased results.

Article Synopsis
  • The study aimed to evaluate a blood test that measures MxA and CRP levels to differentiate between viral and bacterial respiratory infections in adults.
  • A total of 537 patients were analyzed, leading to the development of a diagnostic equation with high sensitivity for bacterial infections (91.6%).
  • The findings suggest that using MxA and CRP measurements can effectively identify the type of respiratory infection, helping guide appropriate treatment.

The long-term impact of the coronavirus disease 2019 (COVID-19) pandemic is a critical public health concern. The presence of residual symptoms in COVID-19 survivors has been investigated with various results; however, there is limited data documenting outcomes longer than 6 months post-hospitalization. We aimed to investigate the 12-month lasting effects of COVID-19 in hospitalized patients.

Indolent systemic mastocytosis (ISM) represents the most common form of SM, typically following a slow clinical course. While anaphylactic reactions may come up in the life course of an ISM patient, these are often moderate and do not pose a threat to patient's health. Here, we present an undiagnosed case of ISM with recurrent severe anaphylactic episodes following consumption of food and emotional stress.

Since the outbreak of COVID-19, research has been focused on establishing effective treatments, especially for patients with severe pneumonia and hyperinflammation. The role and dose of corticosteroids remain obscure. We evaluated 58 patients with severe COVID-19 during two periods.

Objectives: Interstitial pneumonia with autoimmune features (IPAF) refers to patients with interstitial lung disease and autoimmune features not fulfilling the classification criteria for a specific connective tissue disease. We sought to study the characteristics, disease progression, response to treatment and complications of patients with IPAF in 1-year follow-up period.

Methods: Clinical and laboratory findings, comorbidities, medications, pulmonary function tests (PFTs), chest HRCT and complications during the one-year follow-up period were documented for each of the 39 enrolled patients with IPAF.

Unlabelled: We describe a case of a 40-year-old woman who was admitted to the intensive care unit with a rapid onset of dyspnea and orthopnea. She presented progressive weakness, weight loss and secondary amenorrhea during last year, while intermittent fever was present for the last two months. Initial biochemical evaluation showed anemia, hyponatremia and increased C-reactive protein levels.

Background: Statin treatment is considered as first line therapy in patients with atherosclerotic disease. We evaluated the effect of pre-treatment with statins on carotid plaque infiltration by macrophages and on the circulating levels of proinflammatory cytokines in patients who underwent carotid endarterectomy.

Patients And Methods: One hundred fourteen patients were enrolled; 89 men and 25 women (mean age 67+/-8 years; range 42-83 years).

Background: Treatment with statins is considered a first line therapy in atherosclerotic disease. Intraplaque angiogenesis is involved in plaque progression and instability. It remains unclear whether the beneficial effect of statin treatment in humans is achieved through reduced intraplaque angiogenesis.

Antibodies to beta2-glycoprotein I (anti-beta2GPI) have been associated with recurrent thrombosis and pregnancy morbidity. However, the prevalence of anti-beta2GPI in children suffering from cerebral infarction is unknown. We report on a 20-month-old boy who had an ischemic stroke, secondary to antiphospholipid syndrome with high titers of immunoglobulin G anti-beta2GPI (first titer: 132 U; second titer 6 weeks later: 350 U; normal range: 0-100 U).
