Patients were followed in five outpatient visits: Obtaining baseline data of a population to allow future comparisons is one of the elements that contribute to the good quality of research 18 Dornase alfa proprietary name Pulmozyme from Dornaa is a highly purified solution of recombinant human deoxyribonuclease I rhDNasean enzyme which selectively cleaves DNA.

However, our finding contrasts with results of a randomized study by Frederiksen et al 26who demonstrated a significant reduction of airway colonization by gram-negative or gram-positive bacteria with dornase alfa, with the exception of P. Optimal activity is dependent on the presence of divalent cations such as calcium and magnesium. The safety of dornase alfa has not been studied in pregnant women, nursing women and children under the age of 5 years old.

Dornase Alfa pronounced as door’ nace. It usually is taken one or two times a day.


Part of these results was previously published National Center for Biotechnology InformationU. Due to sample size limitations, no statistical comparisons were made for this group regarding outcomes over time.

Cystic Fibrosis Foundation [cited Sep 20]; drnasa on the Internet]. What should I do if I forget a dose? Table 5 Use of routine concomitant treatments during the study follow-up. Please review our privacy policy. Regarding variations in clinical management of the various centers, regular updating and contact between researchers have minimized differences in basic care approaches and monitoring of patients.

Pulmonary complications of cystic fibrosis. During the first six months of dornase alfa, chronic P. The importance of this publication resides on the fact that it was mostly prospective, following a standardized documentation used in all 16 CF centers, with a significant number of patients. How should this medicine be used?

Dornase Alfa for Non-Cystic Fibrosis Pediatric Pulmonary Atelectasis.

Dornase alfa may be considered as a therapeutic option in non-cystic fibrosis pediatric patients with pulmonary atelectasis, who require treatment intervention when conventional therapy is unsuccessful. Dornase alfa hydrolyzes the DNA in sputum of CF patients and reduces sputum viscosity and viscoelasticity.

A significant reduction in the number of emergency room visits due to acute exacerbations was coincident with improvement in the QoL Respiratory Domain of previous paper The missing data has many reasons as incompletely fulfilled documents, patients’ faults to clinics, physician misunderstanding of proposed questions, and CF younger patients afa of cooperation during pulmonary tests. Extracellular DNA is a viscous anionic polymer and its breakdown appears to improve the viscosity and viscoelasticity of purulent sputum of individuals with CF, thus reducing airflow obstruction.

Dornase alfa is used as an off-label treatment option for pulmonary atelectasis because limited treatment modalities exist after conventional therapy has failed. Free informed consent form was signed by patients or their guardians and this project was approved by human research ethics committees of all Centers Results Of the initial patients, four were excluded for not meeting the inclusion criteria.

What other information should I know? It has no effect on intracellular DNA. Keep all appointments with your doctor and the laboratory. Support Drnasa Support Center. Student’s t -test, chi-square test and analysis of variance were used when appropriated.


Cystic fibrosis overview and update on infant care. Pulmonary function parameters and data related to hospitalization are presented in Tables 1 to 3. Guidelines for diagnosis of cystic fibrosis in newborns through older adults: The role of dornase alfa in the treatment of cystic fibrosis. Retrieved from ” https: It is important to keep all medication out of sight and reach of children as many containers such as weekly pill minders and those for eye drops, creams, patches, and inhalers are not child-resistant and young children can open them easily.

In our study, treatment with dornase alfa did not promote significant changes in a mean FEV 1 after one year of use, as compared to baseline, in all age groups.

Considering that the progressive decline in lung function is a hallmark of CF, maintenance of lung function should be highlighted as an important achievement of the treatment Dornase alfa comes as a solution to inhale by mouth.

This protein therapeutic agent is produced in Chinese hamster ovary cells. The routine concomitant treatments during the study follow-up are shown in Table 5. Clinical use of dornase alfa, a recombinant human deoxyribonuclease I that reduces the viscosity of CF sputum through the hydrolization of DNA accumulated in secretions 11has demonstrated significant efficacy in CF, as it reduces respiratory exacerbations and improves lung function, regardless of patients age or disease stage 512 Ask your doctor, pharmacist, or respiratory therapist to demonstrate the proper technique.

In addition, salt loss syndromes, diabetes mellitusand genitourinary abnormalities are other clinical complications of CF 28.

In the last six months of therapy, chronic or intermittent colonization by P. Fdel, mutation at the CFTR gene in newborns and patients. Inflammatory responses to individual microorganisms in the lungs dornssa children with cystic fibrosis. Before using dornase alfa, tell your doctor and pharmacist if you are allergic to dornase alfa or any other drugs.
