Gene Sequence

Sequence Code 146838

The sequence is quoted from: *****

COVID-19 pneumonia manifests among others with a thick bronhial secretion. It contains an increased number of neutrophil extracellular traps (NETs), formed during netosis. DNA is a major component in NETs. DNAse alfa (Pulmozyme®, Roche) is a recombinant human enzyme, registered for inhalations in patients with Cystic fibrosis, in which NETs are also a typical characteristic. DNAse alfa inhalations are typically well tolerated and with no major side effects. Some initial reports exist of using DNAse alfa inhalations in COVID-19 patients, that had benefitial effects. There are some trials registered with ClinicalTrials, investigating the usufulness of DNAse alfa in intubated patients, but the investigators have no knowledge of a trial, investigating the usufulness of this drug in patients receiving High Flow Nasal Oxygen therapy.

The Effect of PEGylation on Drugs’ Pharmacokinetic Parameters; from Absorption to Excretion

Review

Author: Javadzadeh, Yousef ; Khajeei, Ali ; Gholikhani, Tooba ; Masoomzadeh, Salar

Abstract:Until the drugs enter humans life, they may face problems in transportation, drug delivery, and metabolism. These problems can cause reducing drug’s therapeutic effect and even increase its side effects. Together, these cases can reduce the patient's compliance with the treatment and complicate the treatment process. Much work has been done to solve or at least reduce these problems. For example, using different forms of a single drug molecule (like Citalopram and Escitalopram); slight changes in the drug’s molecule like Meperidine and α-Prodine, and using carriers (like Tigerase®). PEGylation is a recently presented method that can use for many targets. Poly Ethylene Glycol or PEG is a polymer that can attach to drugs by using different methods and resulting sustained release, controlled metabolism, targeted delivery, and other cases. Although they will not necessarily lead to an increase in the effect of the drug, they will lead to the improvement of the treatment process in certain ways. In this article, the team of authors has tried to collect and carefully review the best cases based on the PEGylation of drugs that can help the readers of this article.

ANNOTATIONDornase alfa (Pulmozyme, Tigerase) is a purified solution of recombinant human DNase, clinically developed for the treatment of pulmonary diseases in patients with cystic fibrosis (CF). The action of the drug is aimed at destroying the viscous secretion, rich in DNA strands of neutrophils, through their fragmentation, the density of the secretion decreases, and the aeration of the lower respiratory tract improves. The similarity of pathological processes with the formation of viscous exudate on the surface of the mucous membrane in diseases of the upper respiratory tract and ear initiated studies on the use of Dornase alpha in otorhinolaryngology.MATERIAL AND METHODSThe analysis of materials of domestic and foreign authors on the effectiveness of the use of the drug Dornase alfa in otorhinolaryngology was carried out.RESULTSThe review included 132 patients (10 studies) in whom Dornase alfa was used to treat CF-associated nasal and paranasal sinus diseases. Analysis of the literature revealed only 3 studies, one of which consisted of two parts, examining the effect of Dornase alpha on middle ear exudate: two studies were demonstrated in an animal model; one - in vitro on samples of middle ear effusion which were aspirated through a myringotomy incision from patients with recurrent acute otitis media; and one in clinical 40 patients (40 ears) for hydrolysis of exudate in the tympanostomy tubes.CONCLUSIONAnalysis of studies on the use of Dornase alfa demonstrates an improvement in clinical symptoms in all patients with CF and chronic rhinosinusitis. In experimental studies on an animal model, as well as in vitro research on exudate from the middle ear, Dornase alfa has demonstrated high efficacy and safety. Dornase alfa is a drug with high potential, further research is needed for wider use in ENT practice, especially in otiatrics.

The article presents the results of studies of the drug Tigerase® (inhalation solution manufactured by JSC GENERIUM, Russia), conducted to obtain evidence of its similarity (comparability) to the reference drug Pulmozyme® (inhalation solution, manufactured by Hoffmann-La Roche Ltd., Switzerland). Both drugs contain human recombinant deoxyribonuclease I (dornase alfa) as an active substance and are intended for the treatment of cystic fibrosis with pulmonary manifestations (mucoviscidosis). The enzymatic activity of dornase alfa, contained in the studied drugs, was investigated in vitro and ex vivo on samples of purulent sputum of patients. The pharmacokinetic parameters of the drugs in the blood serum, bronchi, and lungs, as well as the main physiological parameters (body weight and temperature, the state of the cardiovascular, respiratory, excretory systems, hematological and biochemical blood parameters, pathomorphological changes in internal organs (including the state of the cornea), and mortality rates) were investigated in comparative studies of subchronic toxicity in juvenile and mature rats with 28-day inhalation at doses of 0.2 mg/kg for mature animals and 0.26 mg/kg for juvenile animals (the dose was 6 times higher than the dose recommended for clinical use). The results of the studies allow us to conclude that the drugs are comparable in enzymatic, mucolytic (secretolytic) DNase activity, safety profile and main pharmacokinetic parameters.
