Show Abstract · Added March 31, 2018
Patent ductus arteriosus (PDA) is a frequent, complex, and difficult to treat clinical syndrome among preterm infants in the neonatal intensive care unit. In addition to known clinical risk factors, there are emerging data about genetic predisposition to PDA in both animal and human models. Clinical response and toxicity from drugs used to treat PDA are highly variable. Developmental and genetic aspects of pharmacokinetics and pharmacodynamics influence exposure and response to pharmacologic therapies. Given the variable efficacy and toxicity of known drug therapies, novel therapeutic targets for PDA treatment offer the promise of precision medicine. This review addresses the known genetic contributions to prolonged ductal patency, variability in response to drug therapy for PDA, and potential novel drug targets for future PDA treatment discovery.

Cell-Free Hemoglobin-mediated Increases in Vascular Permeability. A Novel Mechanism of Primary Graft Dysfunction and a New Therapeutic Target.
Shaver CM, Wickersham N, McNeil JB, Nagata H, Sills G, Kuck JL, Janz DR, Bastarache JA, Ware LB
(2017) Ann Am Thorac Soc 14: S251-S252
MeSH Terms: Acetaminophen, Capillary Permeability, Endothelial Cells, Hemoglobins, Humans, Lung, Lung Transplantation, Primary Graft Dysfunction
Show Abstract · Added May 31, 2018
RATIONALE - Cell-free hemoglobin (CFH) is a potent oxidant associated with poor clinical outcomes in a variety of clinical settings. Recent studies suggest that acetaminophen (APAP), a specific hemoprotein reductant, can abrogate CFH-mediated oxidative injury and organ dysfunction. Preoperative plasma CFH levels are independently associated with primary graft dysfunction (PGD) after lung transplant ( 1 ).
OBJECTIVES - Our objectives were to determine whether CFH would increase lung vascular permeability in the isolated perfused human lung and whether APAP would limit these effects.
METHODS - Human lungs declined for transplant were inflated and perfused with Dulbecco's modified Eagle medium/5% albumin at a pulmonary artery pressure of 8-12 mm Hg. After steady state was achieved, CFH (100 mg/dl) was added to the perfusate ± APAP (15 μg/ml). Lung permeability was measured by continuous monitoring of lung weight gain and by extravasation of Evans blue dye-labeled albumin from the vasculature into bronchoalveolar lavage. To test the mechanism of increased permeability, human pulmonary microvascular endothelial cells were exposed to CFH (0.5 mg/ml) ± APAP (160 μM) for 24 hours and permeability was assessed by electrical cell-substrate impedance sensing.
MEASUREMENT AND MAIN RESULTS - In the isolated perfused human lung, CFH increased lung permeability over 2 hours compared with control lungs (12% vs. 2% weight gain from baseline, P = 0.03). Increased vascular permeability was confirmed by a 4.8-fold increase in Evans blue dye-labeled albumin in the airspace compared with control lungs. Pretreatment with APAP prevented lung weight gain (P = 0.06 vs. CFH). In human pulmonary microvascular endothelial cells, CFH increased monolayer permeability (P = 0.03 vs. control), and this was attenuated by APAP (P = 0.045 vs. CFH).
CONCLUSIONS - Circulating CFH increases vascular permeability in the isolated perfused human lung and paracellular permeability in lung microvascular endothelial cells. These effects may explain the association of plasma CFH levels with PGD. The hemoprotein reductant APAP attenuates the effects of CFH and merits further exploration as a potential therapy for PGD prevention.

Show Abstract · Added April 18, 2017
BACKGROUND - Nonsteroidal anti-inflammatory drugs (NSAIDs) have been associated with improved survival in some cancers, but evidence for ovarian cancer is limited.
METHODS - Pooling individual-level data from 12 Ovarian Cancer Association Consortium studies, we evaluated the association between self-reported, pre-diagnosis use of common analgesics and overall/progression-free/disease-specific survival among 7694 women with invasive epithelial ovarian cancer (4273 deaths).
RESULTS - Regular analgesic use (at least once per week) was not associated with overall survival (pooled hazard ratios, pHRs (95% confidence intervals): aspirin 0.96 (0.88-1.04); non-aspirin NSAIDs 0.97 (0.89-1.05); acetaminophen 1.01 (0.93-1.10)), nor with progression-free/disease-specific survival. There was however a survival advantage for users of any NSAIDs in studies clearly defining non-use as less than once per week (pHR=0.89 (0.82-0.98)).
CONCLUSIONS - Although this study did not show a clear association between analgesic use and ovarian cancer survival, further investigation with clearer definitions of use and information about post-diagnosis use is warranted.

Show Abstract · Added January 2, 2017
BACKGROUND - Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used and have been linked to acute kidney injury (AKI), chronic kidney disease (CKD) and cardiovascular disease (CVD). Patients who survive an AKI episode are at risk for future adverse kidney and cardiovascular outcomes. The objective of our study was to examine the prevalence and predictors of NSAID use among AKI survivors.
METHODS - The Southern Community Cohort Study is a prospective study of low-income adults aged 40-79 in the southeastern US. Through linkage with Centers for Medicare and Medicaid Services, 826 participants with an AKI diagnosis (ICD-9 584.5-584.9) at any age prior to cohort enrollment were identified. At baseline, data were collected on regular use of prescription and over-the-counter NSAIDs, as well as demographic, medical and other characteristics. Additional comorbidities were ascertained via linkage with CMS or the US Renal Data System.
RESULTS - One hundred fifty-four AKI survivors (19%) reported regular NSAID use at cohort enrollment (52 prescription, 81 OTC, 21 both) and the percentage of NSAID users did not vary by time since AKI event. Over 58% of users were taking NSAIDS regularly both before and after their AKI event. Hypertension (83%), arthritis (71%), heart failure (44%), CKD (36%) and diabetes (35%) were prevalent among NSAID users. In a multivariable model, history of arthritis (OR: 3.00; 95% CI: 1.92, 4.68) and acetaminophen use (OR: 2.43; 95% CI: 1.50, 3.93) were significantly associated with NSAID use, while prevalent CKD (OR: 0.63; 95% CI: 0.41, 0.98) and diabetes (OR: 0.44; 95% CI: 0.29, 0.69) were significantly inversely associated.
CONCLUSIONS - NSAID use among AKI survivors is common and highlights the need to understand physician and patient decision-making around NSAIDs and to develop effective strategies to reduce NSAID use in this vulnerable population.

Show Abstract · Added September 19, 2017
Drug-induced acute kidney injury (AKI) is often encountered in hospitalized patients. Although serum creatinine (SCr) is still routinely used for assessing AKI, it is known to be insensitive and nonspecific. Therefore, our objective was to evaluate kidney injury molecule 1 (KIM-1) in conjunction with microRNA (miR)-21, -200c, and -423 as urinary biomarkers for drug-induced AKI in humans. In a cross-sectional cohort of patients (n = 135) with acetaminophen (APAP) overdose, all 4 biomarkers were significantly (P < .004) higher not only in APAP-overdosed (OD) patients with AKI (based on SCr increase) but also in APAP-OD patients without clinical diagnosis of AKI compared with healthy volunteers. In a longitudinal cohort of patients with malignant mesothelioma receiving intraoperative cisplatin (Cp) therapy (n = 108) the 4 biomarkers increased significantly (P < .0014) over time after Cp administration, but could not be used to distinguish patients with or without AKI. Evidence for human proximal tubular epithelial cells (HPTECs) being the source of miRNAs in urine was obtained first, by in situ hybridization based confirmation of increase in miR-21 expression in the kidney sections of AKI patients and second, by increased levels of miR-21, -200c, and -423 in the medium of cultured HPTECs treated with Cp and 4-aminophenol (APAP degradation product). Target prediction analysis revealed 1102 mRNA targets of miR-21, -200c, and -423 that are associated with pathways perturbed in diverse pathological kidney conditions. In summary, we report noninvasive detection of AKI in humans by combining the sensitivity of KIM-1 along with mechanistic potentials of miR-21, -200c, and -423.

Cardiolipin fatty acid remodeling regulates mitochondrial function by modifying the electron entry point in the respiratory chain.
Vergeade A, Bertram CC, Bikineyeva AT, Zackert WE, Zinkel SS, May JM, Dikalov SI, Roberts LJ, Boutaud O
(2016) Mitochondrion 28: 88-95
MeSH Terms: Acetaminophen, Antipyretics, Cardiolipins, Cell Respiration, Cells, Cultured, Electron Transport, Fatty Acids, Humans, Mitochondria, Myeloid Progenitor Cells, Quinones
Show Abstract · Added April 25, 2016
Modifications of cardiolipin (CL) levels or compositions are associated with changes in mitochondrial function in a wide range of pathologies. We have made the discovery that acetaminophen remodels CL fatty acids composition from tetralinoleoyl to linoleoyltrioleoyl-CL, a remodeling that is associated with decreased mitochondrial respiration. Our data show that CL remodeling causes a shift in electron entry from complex II to the β-oxidation electron transfer flavoprotein quinone oxidoreductase (ETF/QOR) pathway. These data demonstrate that electron entry in the respiratory chain is regulated by CL fatty acid composition and provide proof-of-concept that pharmacological intervention can be used to modify CL composition.

(2016) Clin Chem 62: 77-83
MeSH Terms: Acetaminophen, Biological Products, Computational Biology, Databases, Genetic, Humans, Liver, Mass Spectrometry
Show Abstract · Added December 17, 2018
BACKGROUND - Untargeted multiomics data sets are obtained for samples in systems, synthetic, and chemical biology by integrating chromatographic separations with ion mobility-mass spectrometry (IM-MS) analysis. The data sets are interrogated using bioinformatics strategies to organize the data for identification prioritization.
CONTENT - The use of big data approaches for data mining of massive data sets in systems-wide analyses is presented. Untargeted biological data across multiomics dimensions are obtained using a variety of chromatography strategies with structural MS. Separation timescales for different techniques and the resulting data deluge when combined with IM-MS are presented. Data mining self-organizing map strategies are used to rapidly filter the data, highlighting those features describing uniqueness to the query. Examples are provided in longitudinal analyses in synthetic biology and human liver exposure to acetaminophen, and in chemical biology for natural product discovery from bacterial biomes.
CONCLUSIONS - Matching the separation timescales of different forms of chromatography with IM-MS provides sufficient multiomics selectivity to perform untargeted systems-wide analyses. New data mining strategies provide a means for rapidly interrogating these data sets for feature prioritization and discovery in a range of applications in systems, synthetic, and chemical biology.

(2015) PLoS One 10: e0117625
MeSH Terms: Acetaminophen, Aged, Coronary Artery Bypass, Double-Blind Method, Female, Humans, Infusions, Intravenous, Lipid Peroxidation, Male, Middle Aged, Placebos, Prospective Studies
Show Abstract · Added February 22, 2016
BACKGROUND - Cardiopulmonary bypass (CPB) lyses erythrocytes and induces lipid peroxidation, indicated by increasing plasma concentrations of free hemoglobin, F2-isoprostanes, and isofurans. Acetaminophen attenuates hemeprotein-mediated lipid peroxidation, reduces plasma and urine concentrations of F2-isoprostanes, and preserves kidney function in an animal model of rhabdomyolysis. Acetaminophen also attenuates plasma concentrations of isofurans in children undergoing CPB. The effect of acetaminophen on lipid peroxidation in adults has not been studied. This was a pilot study designed to test the hypothesis that acetaminophen attenuates lipid peroxidation in adults undergoing CPB and to generate data for a clinical trial aimed to reduce acute kidney injury following cardiac surgery.
METHODS AND RESULTS - In a prospective double-blind placebo-controlled clinical trial, sixty adult patients were randomized to receive intravenous acetaminophen or placebo starting prior to initiation of CPB and for every 6 hours for 4 doses. Acetaminophen concentrations measured 30 min into CPB and post-CPB were 11.9 ± 0.6 μg/mL (78.9 ± 3.9 μM) and 8.7 ± 0.3 μg/mL (57.6 ± 2.0 μM), respectively. Plasma free hemoglobin increased more than 15-fold during CPB, and haptoglobin decreased 73%, indicating hemolysis. Plasma and urinary markers of lipid peroxidation also increased during CPB but returned to baseline by the first postoperative day. Acetaminophen reduced plasma isofuran concentrations over the duration of the study (P = 0.05), and the intraoperative plasma isofuran concentrations that corresponded to peak hemolysis were attenuated in those subjects randomized to acetaminophen (P = 0.03). Perioperative acetaminophen did not affect plasma concentrations of F2-isoprostanes or urinary markers of lipid peroxidation.
CONCLUSIONS - Intravenous acetaminophen attenuates the increase in intraoperative plasma isofuran concentrations that occurs during CPB, while urinary markers were unaffected.

Show Abstract · Added January 28, 2015
OBJECTIVES - This trial evaluated the efficacy of acetaminophen in reducing oxidative injury, as measured by plasma F2-isoprostanes, in adult patients with severe sepsis and detectable plasma cell-free hemoglobin.
DESIGN - Single-center, randomized, double-blind, placebo-controlled phase II trial.
SETTING - Medical ICU in a tertiary, academic medical center.
PATIENTS - Critically ill patients 18 years old or older with severe sepsis and detectable plasma cell-free hemoglobin.
INTERVENTIONS - Patients were randomized 1:1 to enteral acetaminophen 1 g every 6 hours for 3 days (n = 18) or placebo (n = 22) with the same dosing schedule and duration.
MEASUREMENTS AND MAIN RESULTS - F2-Isoprostanes on study day 3, the primary outcome, did not differ between acetaminophen (30 pg/mL; interquartile range, 24-41) and placebo (36 pg/mL; interquartile range, 25-80; p = 0.35). However, F2-isoprostanes were significantly reduced on study day 2 in the acetaminophen group (24 pg/mL; interquartile range, 19-36) when compared with placebo (36 pg/mL; interquartile range, 23-55; p = 0.047). Creatinine on study day 3, a secondary outcome, was significantly lower in the acetaminophen group (1.0 mg/dL; interquartile range, 0.6-1.4) when compared with that in the placebo (1.3 mg/dL; interquartile range, 0.83-2.0; p = 0.039). There was no statistically significant difference in hospital mortality (acetaminophen 5.6% vs placebo 18.2%; p = 0.355) or adverse events (aspartate aminotransferase or alanine aminotransferase > 400; acetaminophen 9.5% vs placebo 4.3%; p = 0.599).
CONCLUSIONS - In adults with severe sepsis and detectable plasma cell-free hemoglobin, treatment with acetaminophen within 24 hours of ICU admission may reduce oxidative injury and improve renal function. Additional study is needed to confirm these findings and determine the effect of acetaminophen on patient-centered outcomes.

Show Abstract · Added April 9, 2015
BACKGROUND - We evaluated the clinical effectiveness of variable courses of paracetamol on patent ductus arteriosus (PDA) closure and examined its effect on the in vitro term and preterm murine ductus arteriosus (DA).
METHODS - Neonates received one of the following three paracetamol regimens: short course of oral paracetamol (SCOP), long course of oral paracetamol (LCOP), and intravenous paracetamol (IVP) for 2-6 d. Pressure myography was used to examine changes in vasomotor tone of the preterm and term mouse DA in response to paracetamol or indomethacin. Their effect on prostaglandin synthesis by DA explants was measured by mass spectroscopy.
RESULTS - Twenty-one preterm infants were included. No changes in PDA hemodynamics were seen in SCOP infants (n = 5). The PDA became less significant and eventually closed in six LCOP infants (n = 7). PDA closure was achieved in eight IVP infants (n = 9). On pressure myograph, paracetamol induced a concentration-dependent constriction of the term mouse DA, up to 30% of baseline (P < 0.01), but required >1 µmol/l. Indomethacin induced greater DA constriction and suppression of prostaglandin synthesis (P < 0.05).
CONCLUSION - The clinical efficacy of paracetamol on PDA closure may depend on the duration of treatment and the mode of administration. Paracetamol is less potent than indomethacin for constriction of the mouse DA in vitro.
