Abstract
Background and objective Acute lung injury (ALI)/ acute respiratory distress syndrome (ARDS) was increasingly recognized as one of the most severe acute hyperimmune response of coronavirus disease 2019 (COVID-19). Clofazimine (CFZ) has attracted attention due to its anti-inflammatory property in immune diseases as well as infectious diseases. However, the role and potential molecular mechanism of CFZ in anti-inflammatory responses remain unclear. Methods We analyze the protein expression profiles of CFZ and LPS from Raw264.7 macrophages using quantitative proteomics. Next, the protective effect of CFZ on LPS-induced inflammatory model is assessed, and its underlying mechanism is validated by molecular biology analysis. Results LC–MS/MS-based shotgun proteomics analysis identified 4746 (LPS) and 4766 (CFZ) proteins with quantitative information. The key proteins and their critical signal transduction pathways including TLR4/NF-κB/HIF-1α signaling was highlighted, which was involved in multiple inflammatory processes. A further analysis of molecular biology revealed that CFZ could significantly inhibit the proliferation of Raw264.7 macrophages, decrease the levels of TNF-α and IL-1β, alleviate lung histological changes and pulmonary edema, improve the survival rate, and down-regulate TLR4/NF-κB/HIF-1α signaling in LPS model. Conclusion This study can provide significant insight into the proteomics-guided pharmacological mechanism study of CFZ and suggest potential therapeutic strategies for infectious disease.

[PMID: 29748073 DOI: 10.1016/j.bjps.2018.03.013] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2017] [Revised: 02/16/2018] [Accepted: 03/10/2018] [Indexed: 12/01/2022]
Abstract
BACKGROUND Post-surgical pyoderma gangrenosum (PSPG) is a rare inflammatory skin disorder of unknown aetiology. Given its similar presentation to wound infection and lack of reliable diagnostic tests as well as pathognomonic clinical features, PSPG is difficult to diagnose. The aim of this review was to identify factors contributing to PSPG to aid with timely diagnosis and appropriate therapy. METHODS A systematic literature review was performed by following PRISMA guidelines, focusing on PSPG after reconstructive and aesthetic breast surgery. The online databases PubMed, Medline, EMBASE, Scopus, and Cochrane were used, and additionally, a Google© search was performed. RESULTS A total of 68 articles describing 87 cases of PSPG following aesthetic and reconstructive breast surgery were found. The majority of PSPG (44%) occurred after breast reduction surgery and microsurgical breast reconstruction (16%). The most common associated conditions were malignancies in 37% and autoimmune deficiencies in 17%. Microbiological examinations were found to have a negative result in 90%. The median time from initial presentation with symptoms to correct diagnosis of PG was on average 12.5 days, with unsuccessful first-line therapy on average for 20.0 days. After the diagnosis of PG, medical therapy most commonly involved steroids in 84% and/or Cyclosporine A in 22% of the cases. On average, the duration of this therapy was 4.7 months. CONCLUSION The diagnosis of PSPG remains a challenging issue. However, according to the presented review, several distinct clinical signs in combination with lack of treatment response should prompt further investigation to promote timely diagnosis and correct treatment of this potentially debilitating disease.
