Inflammation-Associated Tubulopathy in Patients with Acute Bacterial Infections.

Background: Acute kidney injury associated with the underlying inflammatory process of an acute bacterial infection affects patient morbidity and mortality. Clinicians use creatinine and estimated glomerular filtration rate (EGFR) to assess this renal injury, however, these measures may lag behind and change only once significant kidney injury has occurred. Neutrophil gelatinase-associated lipocalin (NGAL) is up-regulated by inflammation and infection and may serve as an early detection biomarker of kidney injury.

Early signaling of inflammation in patients following traumatic injury with accurately estimated time of injury by profiling C-reactive protein levels.

Background: Despite its widespread use, the precise dynamics of CRP response in clinical practice remain poorly defined. We employed a novel quadratic model to explore the time-course analysis of CRP values in trauma patients with known precise time of injury.

Methods: Relevant data on all adult patients admitted to our hospital following traumatic incidents between January 1st 2010 to December 31, 2020 were retrospectively collected.

Normoferremia in Patients with Acute Bacterial Infections-A Hitherto Unexplored Field of the Dichotomy between CRP and Ferritin Expression in Patients with Hyper Inflammation and Failure to Increase Ferritin.

Ferritin is an acute phase response protein, which may not rise as expected in acute bacterial infections. This could be due to the time required for its production or to a lack of response of ferritin to the bacterial inflammatory process. Medical records of hospitalized patients with acute hyper inflammation were retrieved and studied, looking closely at two acute phase proteins: C-reactive protein (CRP) and ferritin.

Impact of care bundles on the occurrence and outcomes of acute kidney injury among patients with ST-segment elevation myocardial infarction.

Background: Several reports suggested that compliance with acute kidney injury care bundles among hospitalized patients resulted in improved kidney and patient outcomes. We investigated the effect of acute kidney injury care bundle utilization on the incidence of acute kidney injury and renal outcomes in a large cohort of myocardial infarction patients treated with percutaneous coronary intervention.

Methods: We included patients with myocardial infarction admitted following percutaneous coronary intervention between January 2008 and December 2020.

Detection of Renal Injury Following Primary Coronary Intervention among ST-Segment Elevation Myocardial Infarction Patients: Doubling the Incidence Using Neutrophil Gelatinase-Associated Lipocalin as a Renal Biomarker.

Background: A subgroup of patients with acute kidney injury (AKI) do not fulfil the functional criteria for AKI diagnosis but show elevated levels of new biomarkers reflecting tubular injury, suggesting that these patients suffer "subclinical AKI". We investigated the incidence and possible implications of "subclinical AKI", compared to no and clinical AKI among ST elevation myocardial infarction patients (STEMI) treated with primary coronary intervention (PCI).

Methods: We included 223 patients with STEMI treated with PCI.

Neutrophil Gelatinase-Associated Lipocalin for the Early Prediction of Acute Kidney Injury in ST-Segment Elevation Myocardial Infarction Patients Treated with Primary Percutaneous Coronary Intervention.

Introduction And Objective: Neutrophil gelatinase-associated lipocalin (NGAL), a glycoprotein released by renal tubular cells, can be used as a marker of early tubular damage. We evaluated plasma NGAL level utilization for the identification of acute kidney injury (AKI) among ST-elevation myocardial infarction (STEMI) patients undergoing primary coronary intervention (PCI).

Methods: 131 STEMI patients treated with PCI were prospectively included.

Elevated Neutrophil Gelatinase-Associated Lipocalin for the Assessment of Structural versus Functional Renal Damage among ST-Segment Elevation Myocardial Infarction Patients.

Background: Neutrophil gelatinase-associated lipocalin (NGAL) is an early marker of renal tubular damage. We investigated the incidence and possible implications of elevated NGAL levels (suggesting renal damage) compared to both functional and damage markers (manifested as serum creatinine [sCr] elevation) and no NGAL/sCr change, among -ST-elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PCI).

Methods: We included 131 patients with STEMI treated with PCI.

Elevated neutrophil gelatinase-associated lipocalin levels before contrast media administration among ST-segment elevation myocardial infarction patients treated with primary percutaneous coronary intervention.

Background: Neutrophil gelatinase-associated lipocalin (NGAL) is a glycoprotein released by renal tubular cells upon nephrotoxic or ischemic events and is considered an early marker of tubular damage. We aimed to demonstrate the presence of early renal injury detected by elevated NGAL levels taken before contrast administration in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI).

Patients And Methods: We prospectively included 88 patients with STEMI treated with PCI.

Induced sputum eosinophilia in ulcerative colitis patients: the lung as a mirror image of intestine?

Background: Ulcerative colitis (UC) is a systemic disease of unknown etiology with extra-intestinal manifestation. Induced sputum (IS) non-invasively assesses extrapulmonary involvement in Crohn's disease. We sought to determine whether there is a cellular marker of lung injury in UC patients detectable by IS.

Hydrogen peroxide in exhaled breath condensate (EBC) vs eosinophil count in induced sputum (IS) in parenchymal vs airways lung diseases.

We compared exhaled breath condensate (EBC) and induced sputum (IS) for assessing inflammation in pulmonary diseases in patients with obstructive lung disease (n = 20), persistent cough >6 months (n = 20), interstitial lung disease (n = 25) and controls (n = 10). EBC was collected by suspending a Teflon perfluoroalkoxy tube installed in an ice-filled container and connected to a polypropylene test tube. IS was recovered after 20' inhalation of 3% saline with an ultrasonic nebulizer, and 300 cells were differentially counted in cytospin Giemsa-stained slides.
