Abstract
BACKGROUND Accumulating evidence suggests that oxidative stress is involved in the inflammatory process of atopic dermatitis (AD). Biopyrrins are the end products of the oxidative reaction of bilirubin with reactive oxygen species. The aim of our study was to explore the correlation between urinary biopyrrin levels and AD severity as well as to assess the possible modification of them in AD patients during biologic therapy with human monoclonal antibody dupilumab. METHODS For this purpose, 25 adult patients with moderate-severe AD who were candidates for dupilumab therapy independently from the study, and 15 healthy control subjects, matched by sex and age, were enrolled. Morning urine samples were collected from all study participants. For AD patients, a collection was planned before starting therapy with dupilumab (WO), after 8, 16, 52 weeks (W8, W16, W52, respectively), and two years (Y2) of treatment. The analysis of urinary levels of biopyrrins was performed by ELISA assay. RESULTS Our results demonstrated that urinary biopyrrin levels were significantly augmented in AD patients, and interestingly they correlated with disease severity. Furthermore, dupilumab therapy decreased levels of urinary biopyrrins in AD patients after eight and 16 weeks, maintaining the result after 52 weeks as well as after two years of treatment. The correlation analysis showed a statistically significant positive correlation between the urinary concentration of biopyrrins and EASI Index, circulating total IgE as well as plasma C reactive protein levels. CONCLUSIONS Dupilumab therapy was able to ameliorate oxidative state in AD patients.

Abstract
Bilirubin is the principal product of heme catabolism. High concentrations of the pigment are neurotoxic, yet slightly elevated levels are beneficial. Being a potent antioxidant, oxidative transformations of bilirubin occur in vivo and lead to various oxidized fragments. The mechanisms of their formation, intrinsic biological activities, and potential roles in human pathophysiology are poorly understood. Degradation methods have been used to obtain samples of bilirubin oxidation products for research. Here, we report a complementary, fully synthetic method of preparation. Our strategy leverages repeating substitution patterns in the parent tetracyclic pigment. Functionalized ready-to-couple γ-lactone, γ-lactam, and pyrrole monocyclic building blocks were designed and efficiently synthesized. Subsequent modular combinations, supported by metal-catalyzed borylation and cross-coupling chemistries, translated into the concise assembly of the structurally diverse bilirubin oxidation products (BOXes, propentdyopents, and biopyrrins). The discovery of a new photoisomer of biopyrrin A named lumipyrrin is reported. Synthetic bilirubin oxidation products made available in sufficient purity and quantity will support future in vitro and in vivo investigations.

Abstract
Oxidative stress is important in the pathogenesis of atopic dermatitis (AD); it can damage keratinocytes, increase dermal inflammation, and reduce skin barrier function, the hallmarks of atopic dermatitis pathogenesis. Measuring oxidative stress is possible by identifying peripheral markers, which could have a predictive value of disease severity, disease progression and response to therapy, with a potentially significant impact on patient management. Our review explored this fascinating field of research, focusing on old and new possible biomarkers that may represent an effective tool to investigate the inflammatory-oxidative axis in AD, adding clinically important information to patient care.

Abstract
OBJECTIVES The aims of the study are to measure the prevalence and level of occupational stress (OS) and to explore its association with oxidative stress among some brickfield workers. METHODS Eighty-six brickfield workers and 90 administrative controls were assessed using the Arabic validated version of the Occupational Stress Index. The urinary levels of oxidative biomarkers; 8-hydroxy-2'-deoxyguanosine and biopyrrins were also measured. RESULTS The prevalence of moderate and severe OS in addition to the urinary levels of both oxidative biomarkers was significantly higher among the brickfield workers compared with their controls. Both biomarkers levels were significantly and positively correlated with scores of Occupational Stress Index, duration of employment, and with each other. The receiver operating characteristic analysis showed significant specificity and sensitivity of both biomarkers for determining the level of OS. CONCLUSIONS A significant association between occupational and oxidative stresses was detected in brickfield workers.

[PMID: 35204165 PMCID: PMC8868066 DOI: 10.3390/antiox11020282] [Citation(s) in RCA: 30] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2022] [Revised: 01/26/2022] [Accepted: 01/28/2022] [Indexed: 02/04/2023] Open
Abstract
Psoriasis is a chronic, immune-mediated inflammatory dermatosis characterized by the appearance of erythematous plaques, covered by white scales, occasionally pruritogenic, and distributed mainly on the extensor areas. Oxidative stress is defined as an imbalance or a transient or chronic increase in the levels of free oxygen/nitrogen radicals, either as a result of the exaggerated elevation in their production or the decrease in their ability to be eliminated by antioxidant systems. Although the pathogenesis of psoriasis remains far from elucidated, there are studies that delineate an involvement of oxidative stress in this skin disorder. Thus, a systematic search was computed in PubMed/Medline, Web of Science and SCOPUS and, in total, 1293 potentially eligible articles exploring this research question were detected. Following the removal of duplicates and the exclusion of irrelevant manuscripts based on the screening of their titles and abstracts (n = 995), 298 original articles were selected for full-text review. Finally, after we applied the exclusion and inclusion criteria, 79 original articles were included in this systematic review. Overall, the data analyzed in this systematic review point out that oxidative stress markers are elevated in psoriasis and share an association with the duration and severity of the disease. The concentrations of these biomarkers are impacted on by anti-psoriasis therapy. In addition, the crosstalk between psoriasis and oxidative stress is influenced by several polymorphisms that arise in genes encoding markers or enzymes related to the redox balance. Although the involvement of oxidative stress in psoriasis remains undisputable, future research is needed to explore the utility of assessing circulating serum, plasma, urinary and/or skin biomarkers of oxidative stress and of studying polymorphisms in genes regulating the redox balance, as well as how can these findings be translated into the management of psoriasis, as well in understanding its pathogenesis and evolution.

Abstract
Background Biopyrrins are end products of oxidation reactions of bilirubin with reactive oxygen, and urinary biopyrrin (UBP) levels might increase under oxidative stress. The authors examined the reference UBP level for healthy adults and its physiological variation in 40 healthy volunteers recruited from among students of our university (20 students each from third-year and fourth-year), and compared the results with data on 8-hydroxy-2-deoxyguanosine (8OHdG). Methods UBP and 8OHdG levels could be considered as oxidative stress markers. The UBP levels were measured with a competitive ELISA kit using biopyrrin antibody 24G7, according to the manufacturer's protocol. 8OHdG levels were measured with a Highly Sensitive 8-OHdG Check kit. UBP and 8OHdG measurements were performed in triplicate and means values calculated. For both parameters, creatinine (Cr) correction was performed using urinary creatinine levels measured by an enzymatic method. Results A comparison of the UBP levels between different grades revealed that the third-year students under high stress from clinical training and other course work tended to have a higher UBP level than fourth-year students. Therefore, we compared the current UBP levels in fourth-year students (samples collected in 2018) with their UBP level when they were in the third-year (samples collected in 2017) to examine the annual change. We found that the UBP level in 2017 samples was significantly higher than that in 2018 samples (P < 0.05). No difference in the 8OHdG level. Additionally, no effect of menstrual stress on the UBP level was observed. Conclusions These results suggest that the UBP levels may be related to school-related stress and menstruation has no effects on urinalysis results.
