About this study
There are consistent evidences through epidemiologic studies in different places, reinforced by occupational asthma records studies, that cleaning workers have a high risk in developing asthma. These risk determinants are not totally known. The air around the worker may have some higher and lower molecular weight with different concentration peaks from removed dust of the cleaning process and volatile substances from cleaning products. Cleaning activities may occur in different places. Although the relationship between rhinitis and asthma is already established, there are not many studies about occupational rhinitis-related work place. This study aimed to investigate airway inflammation and respiratory symptoms of cleaning workers from different workplaces.
Read the detailed description
Were recruited to participate in the study individuals from four different workplaces: Hospital; University; Housekeeper and Control (office workers). The research was performed in Cacoal city, Rondonia, Brazil. Smokers (active), pregnant, lactating, and individuals at continuing therapy for treating disorders of the airways were excluded.
Clinical profile and respiratory symptoms employees evaluation were performed using the European Community Respiratory Health Survey for occupational diseases evaluation (ECRHS), and the International Study of Asthma and Allergies in Childhood (ISAAC) - Asthma module.
Nasal swab was collected for evaluation of upper airways inflammation, according to Ronchetti et al protocol, using a sterile swab that was moistened with 1mL saline solution; both nostrils were scraped using this swab. Twenty minutes after this, laminas were stained using May-Grunwald-Giemsa to eosinophils, neutrophils, lymphocytes, macrophages and epithelial cells identification. Cells were analyzed using a Nikon E600 optical microscope (Nikon, Canada), of 1.000 x magnitude. Whenever possible a total of 200 cells were counted in two slides.
Statistical analysis were performed using Anova variance (Kruskal-Wallis) and Dunn's test for comparisons between groups. To evaluate the association between the qualitative variables we used the chi-square, Statistical software Sigma Plot 12.0 and SPSS 21.0. The confidence interval was 95% (p <0.05).

The air around the worker may have some higher and lower molecular weight with different concentration peaks from removed dust of the cleaning process and volatile substances from cleaning products. Cleaning activities may occur in different places. Although the relationship between rhinitis and asthma is already established, there are not many studies about occupational rhinitis-related work place.

Questions about this trial
What is this clinical trial studying?
A study testing Nasal swab and Questionnaires in people with Inflammation and Work Related Illnesses, run by University of Sao Paulo at 1 site in Brazil.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 30 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
