Efficacy of Daily IV Administration of Dornase Alfa Up to 14 Days Post Subarachnoid Hemorrhage on Functional Independence At 6 Months: a PROBE Multicenter Open-label Randomized Controlled Trial

Subarachnoid hemorrhage due to aneurysm rupture (SAH) results in high mortality, while survivors frequently suffer reduced quality of life and even loss of autonomy, particularly in the active population. A significant proportion of this morbidity and mortality is linked to the occurrence of delayed cerebral ischemia (DCI), defined as a new focal neurological deficit or reduced level of consciousness unrelated to the treatment of the aneurysm or a concomitant condition.
DCI mainly occurs between days 4 and 14 after SAH, with an estimated incidence of 30%, and is significantly associated with an unfavorable functional prognosis at 3 months. Currently, the only treatment for post-SAH DCI is to prevent or reverse the onset of vasospasm, with limited efficacy, for example through nimodipine administration or hemodynamic optimization. However, according to existing data, vasospasm is not the only cause of DCI, as it may occur elsewhere than in the arterial territory affected by vasospasm, or even in the absence of any vasospasm at all. Recent reviews of the literature highlight the role of microvascular thrombo-inflammation in the pathophysiology of DCI.
This phenomenon begins as soon as SAH occurs, with the appearance of multiple microvascular obstructions responsible for ischemia of downstream territories and loss of distal autoregulatory capacity. Among the effectors of thrombo-inflammation, the NETose phenomenon (production of NETs - Neutrophil Extracellular Traps or extracellular DNA network) has recently been associated with the onset of DCI. Indeed, the concentration of NETs increases in the cerebrospinal fluid (CSF) and blood of SAH patients, and correlates with the severity of the hemorrhage. Furthermore, intravenous or intraperitoneal administration of DNAse in an animal model of SAH has been shown to reduce NET concentration and improve functional prognosis by acting directly on cerebral perfusion through the reduction of micro-thrombosis.
In humans, recombinant DNAse (dornase alfa, Pulmozyme®) has marketing authorization for inhaled administration in cystic fibrosis. The toxicology report accompanying the marketing authorization demonstrates the absence of serious side effects following administration of high IV doses of Pulmozyme® in monkeys and rats. Other studies evaluating IV administration of bovine DNAse at high doses report no complications.
In 1999, a study was published evaluating intravenous (IV) Pulmozyme® in lupus patients, reporting no serious adverse events (SAEs) among the 14 patients receiving the treatment. We are currently conducting a clinical trial of the same molecule in IV administration in patients treated with mechanical thrombectomy and IV thrombolysis for ischemic stroke (NCT04785066).
This study is the first randomized clinical trial to target NETs as effectors of the thrombo-inflammation responsible for post-HSA DCI.

Advances in preparation of acellular human dermis for tissue banking and transplantation

Article

Author: Barrera, Valentina ; Randles, Michael ; Stern, Irit ; Rooney, Paul

Abstract:

Non-healing wounds cost the National Health Service over £5.6 billion annually in wound management. Skin allografts are used to treat non-healing wounds, ulcers and burns, offering the best protection against infection. In order to allow host cells to repopulate and to avoid immunogenicity, cell components are removed through decellularisation. Decellularisation of human dermis has so far been performed in NHS Blood and Transplant using a combination of two enzymes (RNase T1 and the recombinant human DNase Pulmozyme)®. This study aims at validating a new method to remove DNA from donated dermis via the use of a single enzyme, Benzonase, known for its effectiveness of DNA digestion. Skin samples were decellularised by removing the epidermis, lysing of dermal cells, removal of cellular fragments by a detergent wash and removal of nucleic acids by a nuclease incubation with either Benzonase or Pulmozyme + RNase T1. DNA quantification with PicoGreen, as well as histology on wax-embedded biopsies, stained with DAPI and haemotoxylin and eosin, were performed. In vitro toxicity test on human osteosarcoma immortalised cells and skin fibroblasts, and biomechanical (tensile) testing, were also performed. The effectiveness of DNA digestion with the new methodology was comparable to previous procedure. Mean DNA removal percentage following decellularisation with Pulmozyme + RNase was 99.9% (3.83 ng/mg). Mean DNA removal percentage with Benzonase was 99.8% (9.97 ng/mg). Histology staining showed complete decellularisation following either method. Benzonase was proven to be non-toxic to both cell lines used, and a one-way Anova test showed no significant difference in neither stress nor strain between acellular dermal matrix decellularised with either Benzonase or Pulmozyme + RNase T1. Benzonase was able to effectively decellularise dermis after prior removal of epidermis. It performed just as well as the combination of Pulmozyme + RNase T1, but represents significant advantages in terms of cost effectiveness, procurement and storage; Benzonase has been successfully used in the decellularisation of other tissues, thus would be better for Tissue Banking use. Switching to this combined DNase/RNase can have far-reaching consequences in the production of acellular human dermal matrix by NHSBT and in the treatment of patients requiring it.

Neutrophil Extracellular Traps Regulate Surgical Brain Injury by Activating the cGAS-STING Pathway

Article

Author: Xu, Lixia ; Wu, Qiaoli ; Cui, Yang ; Li, Bingbing ; Shi, Qi ; Wang, Zhengang ; Tong, Xiaoguang ; Fan, Weijia ; Yan, Hua

Abstract:

Surgical brain injury (SBI), induced by neurosurgical procedures or instruments, has not attracted adequate attention. The pathophysiological process of SBI remains sparse compared to that of other central nervous system diseases thus far. Therefore, novel and effective therapies for SBI are urgently needed. In this study, we found that neutrophil extracellular traps (NETs) were present in the circulation and brain tissues of rats after SBI, which promoted neuroinflammation, cerebral edema, neuronal cell death, and aggravated neurological dysfunction. Inhibition of NETs formation by peptidylarginine deiminase (PAD) inhibitor or disruption of NETs with deoxyribonuclease I (DNase I) attenuated SBI-induced damages and improved the recovery of neurological function. We show that SBI triggered the activation of cyclic guanosine monophosphate–adenosine monophosphate synthase stimulator of interferon genes (cGAS-STING), and that inhibition of the cGAS-STING pathway could be beneficial. It is worth noting that DNase I markedly suppressed the activation of cGAS-STING, which was reversed by the cGAS product cyclic guanosine monophosphate–adenosine monophosphate (cGMP-AMP, cGAMP). Furthermore, the neuroprotective effect of DNase I in SBI was also abolished by cGAMP. NETs may participate in the pathophysiological regulation of SBI by acting through the cGAS-STING pathway. We also found that high-dose vitamin C administration could effectively inhibit the formation of NETs post-SBI. Thus, targeting NETs may provide a novel therapeutic strategy for SBI treatment, and high-dose vitamin C intervention may be a promising translational therapy with an excellent safety profile and low cost.Graphical AbstractThe schematic diagram shows the formation of NETs activated cGAS-STING pathway after SBI, leading to increased microglia activation, accompanied with elevation of inflammatory factors, which in turn aggravated brain injury.

Qingxin Jieyu Granule alleviates myocardial infarction through inhibiting neutrophil extracellular traps via activating ANXA1/FPR2 axis

Article

Author: Kong, Xiangying ; Bai, Ruina ; Su, Xiaohui ; Liu, An ; Zhang, Xinzhuo ; Wang, Jingbo ; Huang, Helan ; Gao, Zhuye ; Qi, Mingzhu ; Huang, Fengyu ; Li, Zhuohang ; Chen, Peiping ; Quan, Jianye ; Chen, Chang

BACKGROUND:

Myocardial infarction (MI), representing the most severe manifestation of coronary artery disease (CAD), stands as a primary concern in the prevention and management of cardiovascular diseases. Clinical evidence demonstrates that Qingxin Jieyu Granule (QXJYG) is efficacious in treatment of MI patients. However, the mechanisms underlying its therapeutic effects remain to be elucidated.

PURPOSE:

This study aimed to evaluate the effects of QXJYG on MI and investigate its underlying mechanisms.

MATERIALS AND METHODS:

The MI model in rats was developed through ligating the left anterior descending (LAD) artery. The effect of QXJYG on cardiac function impairment in MI rats was assessed by echocardiography, while the improvement of cardiomyocyte morphology and myocardial fibrosis after treatment with QXJYG was evaluated through hematoxylin-eosin (H&E) staining and Masson staining. The chemical constituents of QXJYG in blood were identified by using the UPLC-Q-TOF/MS technique. Furthermore, the molecular mechanism underlying the QXJYG therapeutic effect in MI was postulated based on the disease gene-drug target network analysis. Other technical methods such as ELISA, immunohistochemical staining, Western Blot analysis and application of pharmacological inhibitors were employed to verify the effectiveness of QXJYG in treating MI and explore its potential molecular targets.

RESULTS:

The cardiac function in experimental rats post-MI was significantly impaired, as evidenced by an enlarged infarction area, disordered arrangement of cardiomyocytes, and aggravated myocardial fibrosis. QXJYG treatment significantly enhanced the cardiac function and reduced the pathological damage of the cardiac tissue in MI rats. Through the network pharmacology analysis, we identified that FPR2 might be a potential target of QXJYG in its cardiac protection role. QXJYG markedly downregulated the level of neutrophil extracellular traps (NETs) in MI rats, specifically manifested as a significant reduction in the Histone-DNA level and expression of myeloperoxidase (MPO) and citrullinated histone H3 (CitH3) proteins. Furthermore, QXJYG upregulated the levels of ANXA1 and FPR2 proteins in MI rats. The level of FPR2 was markedly reduced in MI rats upon administration of WRW4, a specific inhibitor of FPR2, which was associated with exacerbated MI injury and an elevated level of NETs. When WRW4 was co-administered with QXJYG, the cardioprotective effects of QXJYG on MI were significantly diminished. However, the addition of DNase I did not result in significant changes of the outcomes in MI rats after QXJYG intervention.

CONCLUSION:

QXJYG treatment alleviates cardiac tissue injury in MI rats by inhibiting NETs through activating the ANXA1/FPR2 axis. The findings extend our understanding of the therapeutic effectiveness of QXJYG and offer a scientific foundation for the clinical utilization of QXJYG.
