Increased Oxidative Stress and Decreased Citrulline in Blood Associated with Severe Novel Coronavirus Pneumonia in Adult Patients. Int J Mol Sci 2024; 25:8370. [PMID: 39125944 PMCID: PMC11313210 DOI: 10.3390/ijms25158370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2024] [Revised: 07/28/2024] [Accepted: 07/29/2024] [Indexed: 08/12/2024] Open
Abstract
This study investigated the correlation between oxidative stress and blood amino acids associated with nitric oxide metabolism in adult patients with coronavirus disease (COVID-19) pneumonia. Clinical data and serum samples were prospectively collected from 100 adult patients hospitalized for COVID-19 between July 2020 and August 2021. Patients with COVID-19 were categorized into three groups for analysis based on lung infiltrates, oxygen inhalation upon admission, and the initiation of oxygen therapy after admission. Blood data, oxidative stress-related biomarkers, and serum amino acid levels upon admission were compared in these groups. Patients with lung infiltrations requiring oxygen therapy upon admission or starting oxygen post-admission exhibited higher serum levels of hydroperoxides and lower levels of citrulline compared to the control group. No remarkable differences were observed in nitrite/nitrate, asymmetric dimethylarginine, and arginine levels. Serum citrulline levels correlated significantly with serum lactate dehydrogenase and C-reactive protein levels. A significant negative correlation was found between serum levels of citrulline and hydroperoxides. Levels of hydroperoxides decreased, and citrulline levels increased during the recovery period compared to admission. Patients with COVID-19 with extensive pneumonia or poor oxygenation showed increased oxidative stress and reduced citrulline levels in the blood compared to those with fewer pulmonary complications. These findings suggest that combined oxidative stress and abnormal citrulline metabolism may play a role in the pathogenesis of COVID-19 pneumonia.

Abstract
Background & objectives High expression of arginase gene and its elevated level in serum and bronchial lavage reported in animal models indicated an association with the pathogenesis of asthma. This study was undertaken to assess the serum arginase activity in symptomatic asthma patients and healthy controls and to correlate it with cytokine levels [interleukin (IL)-4 and IL-13] and arginase I (ARG1) gene polymorphism. Methods Asthma was confirmed by lung function test according to the GINA guidelines in patients attending Allergy and Pulmonology Clinic, Bhagwan Mahavir Hospital and Research Centre, Hyderabad, India, a tertiary care centre, during 2013-2015. Serum arginase was analyzed using a biochemical assay, total IgE and cytokine levels by enzyme-linked immunosorbent assay and genotyping of ARG1 for single-nucleotide polymorphisms (SNPs) rs2781666 and rs60389358 using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results There was a significant two-fold elevation in the arginase activity in asthmatics as compared to healthy controls which correlated with disease severity. Non-atopic asthmatics showed elevated activity of arginase compared to atopics, indicating its possible role in intrinsic asthma. Levels of serum IL-13 and IL-4 were significantly high in asthma group which correlated with disease severity that was assessed by spirometry. A positive correlation was observed between arginase activity and IL-13 concentration. Genetic analysis of ARG1 SNPs revealed that rs2781666 G/T genotype, T allele and C-T haplotype (rs60389358 and rs2781666) were associated with susceptibility to asthma. Interpretation & conclusions This study indicated that high arginase activity and IL-13 concentration in the serum and ARG1 rs2781666 G/T genotype might increase the risk of asthma in susceptible population. Further studies need to be done with a large sample to confirm these findings.

Abstract
BACKGROUND Asthma is a complex lung disease resulting from the interplay of genetic and environmental factors. To understand the molecular changes that occur during the development of allergic asthma without genetic and environmental confounders, an experimental model of allergic asthma in mice was used. Our goals were to (1) identify changes at the small molecule level due to allergen exposure, (2) determine perturbed pathways due to disease, and (3) determine whether small molecule changes correlate with lung function. METHODS In this experimental model of allergic asthma, matched bronchoalveolar lavage (BAL) fluid and plasma were collected from three groups of C57BL6 mice (control vs sensitized and/or challenged with ovalbumin, n=3-5/group) 6 hour, 24 hour, and 48 hour after the last challenge. Samples were analyzed using liquid chromatography-mass spectrometry-based metabolomics. Airway hyper-responsiveness (AHR) measurements and differential cell counts were performed. RESULTS In total, 398 and 368 dysregulated metabolites in the BAL fluid and plasma of sensitized and challenged mice were identified, respectively. These belonged to four, interconnected pathways relevant to asthma pathogenesis: sphingolipid metabolism (P=6.6×10-5 ), arginine and proline metabolism (P=1.12×10-7 ), glycerophospholipid metabolism (P=1.3×10-10 ), and the neurotrophin signaling pathway (P=7.0×10-6 ). Furthermore, within the arginine and proline metabolism pathway, a positive correlation between urea-1-carboxylate and AHR was observed in plasma metabolites, while ornithine revealed a reciprocal effect. In addition, agmatine positively correlated with lung eosinophilia. CONCLUSION These findings point to potential targets and pathways that may be central to asthma pathogenesis and can serve as novel therapeutic targets.

Abstract
This study evaluated the associations between job strain and arginase I in 378 healthy Japanese factory workers by a cross-sectional study measuring nitric oxide (NO)-related parameters (arginase I, L-arginine, exhaled nitric oxide (FeNO), and NOx), clinical parameters, and job strain using a Japanese version of the Job Content Questionnaire by Karasek. Arginase I and FEV1% were negatively correlated with job strain and positively correlated with job control and social support. FeNO and hs-CRP were negatively correlated with job strain. Multiple regression analysis showed negative association of arginase I with job strain and positive association with job control and social support in females. It is concluded that serum levels of arginase I may be useful biomarkers for the diagnosis of job stress in healthy female workers, although many factors can be influencing the data.

Abstract
The relationship between exercise training and nitric oxide-related parameters was examined in a cross-sectional study and an intervention study. A cross-sectional study using 184 employees was conducted to observe the association of exercise habits with serum arginase (ELISA and activity), l-arginine, l-citrulline, l-ornithine, NOx, exhaled nitric oxide, blood pressure, FEV1%, hs-CRP, HDL-cholesterol, IgE, and life style factors. An intervention study was also conducted to evaluate the changes of serum arginase I, nitric oxide-related parameters, and mRNA levels of anti-oxidant enzymes in blood monocytes before and after 1 h of aerobic exercise training per day for a month. Exercise habits were associated with increased arginase activity and a moderate alcohol drinking habit, after adjustment with several covariates. Aerobic exercise training induced a decrease in l-arginine and diastolic blood pressure and induced an increase in NO2− and urea. Moreover, mRNA expression of anti-oxidant enzymes, such as catalase and GPX1, and a life elongation enzyme, SIRT3, were significantly increased after aerobic exercise. The results that aerobic exercise training increased NO generation, reduced blood pressure, and induced anti-oxidant enzymes via SIRT3 suggest that exercise training may be an important factor for the prevention of disease by inducing intrinsic NO and anti-oxidant enzymes.

Abstract
The relationship between serum arginase I and serum l-arginine or fractional exhaled nitric oxide (FENO) was evaluated cross-sectionally in asthmatic patients. No sex difference was observed in the serum mean levels of arginase I and l-arginine or FENO. Arginase I and FENO were higher in patients 60 or younger years than in those over 60 years. Asthmatic patients were divided into three groups: no steroid therapy, inhalation steroid therapy, and oral steroid therapy. Arginase I, FENO and high-sensitivity-C-reactive protein (hs-CRP) were significantly lower in the inhalation steroid therapy group than in the no steroid therapy group. Correlations were observed between arginase I and FENO, l-arginine, hs-CRP, WBC, and age, and also between FENO and IgE, WBC, and age. A logistic regression analysis revealed the positive association of arginase I with FENO, and the negative association of l-arginine. FENO was positively associated with arginase I and IgE. These results indicated that serum arginase I might influence serum levels of l-arginine and FENO, and that IgE might influence FENO in asthmatic patients.

Abstract
Changes in l-arginine metabolism, including increased arginase levels and decreased nitric oxide production, are involved in the pathophysiology of asthma. In this study, using an intranasal mite-induced NC/Nga mouse model of asthma, we examined whether administration of l-arginine ameliorated airway hyperresponsiveness and inflammation by altering l-arginine metabolism. Experimental asthma was induced in NC/Nga mice via intranasal administration of mite crude extract (50 µg/day) on 5 consecutive days (days 0-4, sensitization) and on day 11 (challenge). Oral administration of l-arginine (250 mg/kg) was performed twice daily on days 5-10 for prevention or on days 11-13 for therapy. On day 14, we evaluated the inflammatory airway response (airway hyperresponsiveness, the number of cells in the bronchoalveolar lavage fluid, and the changes in pathological inflammation of the lung), arginase expression and activity, l-arginine bioavailability, and the concentration of NOx, the end products of nitric oxide. Treatment with l-arginine ameliorated the mite-induced inflammatory airway response. Furthermore, l-arginine administration attenuated the increases in arginase expression and activity and elevated the NOx levels by enhancing l-arginine bioavailability. These findings indicate that l-arginine administration may contribute to the improvement of asthmatic symptoms by altering l-arginine metabolism.

Abstract
The associations of serum arginase I with serum L-arginine, serum 3-nitrotyrosine, and fractional exhaled nitric oxide (FENO) were evaluated cross-sectionally in healthy Japanese workers. The serum median (minimum-maximum) levels of arginase I, 3-nitrotyrosine, and FENO in healthy people (n = 130) were 14.6 (0.94-108.1) ng/mL, 81.0 (0.27-298.6) pmol/mg protein, and 14.0 (5.0-110.0) parts per billion, respectively. Significant correlations of arginase I with FENO, L-arginine, 3-nitrotyrosine, and percent predicted forced expiratory volume in 1 s (FEV1 (% predicted)) were observed, and correlations of FENO with immunoglobulin E (IgE), NOx, arginase I, and sex and allergy were also observed. By multiple regression analysis, arginase I showed positive associations with FENO and 3-nitrotyrosine, and a negative association with L-arginine; and FENO showed positive associations with IgE and NO2(-) + NO3(-) (NOx), and a negative association with L-arginine, as well as an association with sex. Moreover, logistic regression analysis showed linear inverse associations of arginase I and 3-nitrotyrosine with L-arginine, and showed linear positive associations of FENO with IgE and NOx. It was concluded that serum arginase I might regulate serum L-arginine and 3-nitrotyrosine via L-arginine, and that IgE or NOx might regulate FENO in a healthy Japanese population.

Abstract
OBJECTIVE We reported previously that serum arginase I increased in asthmatic patients and was associated with oxidative stress in a small healthy population. However, the exact association of arginase I with oxidative stress is not known. The present study aimed to analyze the association of arginase I with oxidative stress in a larger healthy population by a newly established ELISA. DESIGN AND METHODS The new ELISA for the measurement of human arginase I was established by generating recombinant arginase I protein in human arginase I gene-transfected Escherichia coli via an ARG1 cDNA fragment-inserted vector and -specific antibody in rabbits. Serum arginase I was evaluated in a cross-sectional study on a healthy population (n=721) by comparing a commercial ELISA kit with the new ELISA. RESULTS The mean levels of serum arginase I were 20.3 ± 0.7 ng/mL and 4.7 ± 0.2 ng/mL using the commercial ELISA kit and the new ELISA, respectively. Arginase I was correlated with WBC, RBC, hs-CRP, 8-OHdG, HDL-c, ALT, and BMI. Logistic regression analysis showed independent positive associations of arginase I with WBC, RBC, and urinary 8-OHdG and inverse independent associations with serum insulin and age. The association of arginase I with hs-CRP was not independent. CONCLUSION The independent associations of arginase I with urinary 8-OHdG and serum insulin may reflect its involvement in oxidative stress and diabetes mellitus.

Kuo L, Hein TW. Vasomotor regulation of coronary microcirculation by oxidative stress: role of arginase. Front Immunol 2013; 4:237.

Abstract
Overproduction of reactive oxygen species, i.e., oxidative stress, is associated with the activation of redox signaling pathways linking to inflammatory insults and cardiovascular diseases by impairing endothelial function and consequently blood flow dysregulation due to microvascular dysfunction. This review focuses on the regulation of vasomotor function in the coronary microcirculation by endothelial nitric oxide (NO) during oxidative stress and inflammation related to the activation of L-arginine consuming enzyme arginase. Superoxide produced in the vascular wall compromises vasomotor function by not only scavenging endothelium-derived NO but also inhibiting prostacyclin synthesis due to formation of peroxynitrite. The upregulation of arginase contributes to the deficiency of endothelial NO and microvascular dysfunction in various vascular diseases by initiating or following oxidative stress and inflammation. Hydrogen peroxide, a diffusible and stable oxidizing agent, exerts vasodilator function and plays important roles in the physiological regulation of coronary blood flow. In occlusive coronary ischemia, the release of hydrogen peroxide from the microvasculature helps to restore vasomotor function of coronary collateral microvessels with exercise training. However, excessive production and prolonged exposure of microvessels to hydrogen peroxide impairs NO-mediated endothelial function by reducing L-arginine availability through hydroxyl radical-dependent upregulation of arginase. The redox signaling can be a double-edged sword in the microcirculation, which helps tissue survival in one way by improving vasomotor regulation and elicits oxidative stress and tissue injury in the other way by causing vascular dysfunction. The impact of vascular arginase on the development of vasomotor dysfunction associated with angiotensin II receptor activation, hypertension, ischemia-reperfusion, hypercholesterolemia, and inflammatory insults is discussed.

Anti-inflammatory effect of arginase inhibitor and corticosteroid on airway allergic reactions in a Dermatophogoides farinae-induced NC/Nga mouse model. Inflammation 2013; 36:141-51.

Abstract
The present study was aimed to investigate the effect of an arginase inhibitor, N-hydroxy-nor-L-arginine (nor-NOHA) and a corticosteroid, prednisolone, in an intranasal mite-induced NC/Nga mouse model of asthma. The treatment with nor-NOHA and prednisolone inhibited the increase in airway hyperresponsiveness, the number of bronchoalveolar lavage fluid cells, protein expression of arginase I and arginase II, messenger RNA (mRNA) expression of nitric oxide synthase (NOS)2 and Th2 cytokines such as interleukin (IL)-4, IL-5, and IL-13, and the pathological inflammatory changes of the lung. NOx levels in the lung were not changed in mice treated with prednisolone and elevated in mice treated with nor-NOHA or prednisolone plus nor-NOHA despite suppressed NOS2 mRNA expression. The study concluded that anti-inflammatory effect by nor-NOHA might be dependent on NO supply from depleted NO by downregulated arginine availability of arginase and was not related with the anti-inflammatory mechanisms by prednisolone.

Abstract
PURPOSE OF REVIEW Many physiologic and pathophysiologic processes are modulated by arginine availability, which can be regulated by arginase. An understanding of the conditions that result in elevated arginase activity as well as the consequences of arginine deficiency is essential for design of effective nutritional support for disease. This review will emphasize recent findings regarding effects of plasma arginase and arginine deficiencies in disease. RECENT FINDINGS Elevations in plasma arginase, derived primarily from hemolysis of red blood cells or liver damage, that are associated with arginine deficiency have been identified in an increasing number of diseases and conditions. Arginine insufficiency not only can activate a stress kinase pathway that impairs function of T lymphocytes but it also can inhibit the mitogen-activated protein kinase signaling pathway required for macrophage production of cytokines in response to bacterial endotoxin/lipopolysaccharide. SUMMARY There are at least two broad categories of arginine deficiency syndromes, involving either T-cell dysfunction or endothelial dysfunction, depending on the disease context in which arginine deficiency occurs. There is limited information regarding the safety and efficacy of supplementation with arginine or its precursor citrulline in ameliorating arginine deficiency in specific diseases, indicating the need for further studies.
