Gender and age risks for hoarseness and dysphonia with use of a dry powder fluticasone propionate inhaler in asthma

The Association Between Work-related Stress, Indoor Air Quality and Voice Problems Among Teachers - Is There a Trend?

INTRODUCTION

Hoarseness and other voice problems are common in occupations where the person has to speak, sing or shout in a work environment containing dust, noise, gaseous or particulate irritants. In recent years, stress has often been associated with voice problems.

OBJECTIVE

The aim of this study was to examine trends over a period of time of the prevalence of voice problems and reported stress in Finnish school buildings.

STUDY DESIGN

School buildings from different parts of the country were studied for ten years using a similar questionnaire (N = 1721). Five schools participated before and after the remediation of an indoor air problem in the school buildings (n = 315).

RESULTS

In the pilot study (2007-2008), the reported work-related stress was on a very low level (3%) and the prevalence of hoarseness was 10%. After the economic crisis in 2008, the stress was observed to have increased. During the follow-up (2008-2017), the reported stress had continued to increase and in the latest surveys it was 21% and the prevalence of hoarseness 34%. Indoor air factors correlated significantly with hoarseness even when controlling for age, gender, owning pets and job satisfaction in a logistic regression model. In the school buildings where the remediation of the building was completed, the prevalence of hoarseness decreased but the level of stress increased. In general, the proportion of respondents reporting stress was lower than the proportion of respondents with hoarseness. Additionally, the reported stress also correlated with factors other than health in the education branch, especially economic resources and major changes in the core curriculum.

CONCLUSION

Hoarseness and work-related stress have, to a large extent, different risk factors. Over time, the proportion of individuals with stress has been at a lower level than the proportion of respondents with voice problems; hence, we conclude that it is quite unlikely that stress would be a causative risk factor for hoarseness. We recommend that irritant dust and gases should be reduced from the work environment of teachers to enable recovery from hoarseness and other voice problems. Coping with work-related stress should be alleviated with other measures.

The prevalence and risk factors of hoarseness among pupils in elementary schools in the South of Finland

Purpose: Hoarseness and voice problems are one of the chronic conditions experienced by children. The aim of this study was to investigate the prevalence of hoarseness, possible risk factors and effects of the remediation of school buildings to the prevalence of hoarseness among school children.Methods: The material was gathered from all the schools in a large city in the south of Finland and the collection method used was an e-mail survey sent to the parents of the pupils and a simultaneous survey sent to the personnel in the schools.Results: All 51 schools participated, and 5889 pupils returned the questionnaire (39%). The exposure data was obtained from two building experts who knew the repair history of the schools. A subjective estimation of the quality of the indoor air was obtained from teachers and the parents. The overall prevalence of hoarseness among pupils was 6.3%; prevalence being higher in unrepaired school buildings than in schools in a good condition or buildings with a thorough remediation. Hoarseness was associated with asthma and allergies, several respiratory symptoms, and respiratory infections. Exposure to tobacco smoke increased the risk, and consumption of caffeine containing drinks seemed to reduce the risk. Noise, stuffiness of the indoor air and microbial smells correlated strongly with the occurrence of hoarseness in a logistic regression model when controlled for age, gender, asthma, passive smoking, and caffeine consumption.Conclusions: We recommend renovations in school buildings with the aim of providing better acoustics, sufficient ventilation, and a reduction in exposure to moisture damage microbes.

A new formulation of fluticasone propionate/salmeterol in a metered-dose inhaler (MDI HFA) allows for the reduction of a daily dose of corticosteroid and provides optimal asthma control - A randomized, multi-center, non-inferiority, phase IV clinical study

BACKGROUND

Improvement of the delivery method of inhaled corticosteroids and subsequent dose reduction can minimize the risk of unfavorable outcomes while providing optimal asthma control.

OBJECTIVE

This randomized, multi-center, non-inferiority, phase IV clinical study compared the efficacy and safety of a new formulation of fluticasone propionate/salmeterol (250 μg/50 μg, twice daily) administered in a metered-dose inhaler hydrofluoroalkane (MDI HFA) with a dry-powder inhaler (DPI) containing fluticasone propionate/salmeterol (500 μg/50 μg, twice daily).

METHODS

Adults with asthma (n = 231) were randomly assigned to either the study group (treated for 12 weeks with fluticasone propionate/salmeterol MDI HFA) or a control group (treated for 12 weeks with fluticasone propionate/salmeterol DPI). Asthma symptoms, exacerbations, short-acting β₂-agonist (SABA) use, physical activity, lung function, and general health status were assessed during four study visits.

RESULTS

Compared with the reference drug, the study drug decreased the incidence of daytime and night-time asthma symptoms, asthma exacerbations, self-administration of SABA, and the limitation of physical activity. Comparable improvement in peak expiratory flow ([MDI HFA] from 6.2 ± 0.2 to 6.6 ± 0.2 l/s vs. [DPI] from 6.0 ± 0.2 to 6.9 ± 0.2 l/s; p > 0.05), forced expiratory volume in one second, and forced vital capacity were obtained in both groups. Significantly lower incidence of hoarseness was observed in the study group ([MDI HFA] 0.0% vs. [DPI] 2.8%; p = 0.0267); no major differences were found for other adverse events.

CONCLUSIONS

Fluticasone propionate/salmeterol (250 μg/50 μg, twice daily) MDI HFA provides optimal asthma control and is non-inferior to fluticasone propionate/salmeterol (500 μg/50 μg, twice daily) DPI.

Effects of Particle Size of Inhaled Corticosteroid on the Voice

OBJECTIVES

The purpose of this study was to determine if inhaled corticosteroid (ICS) particle size influences the development of laryngitis including candida laryngitis, dysphonia, or vocalis muscle atrophy in asthmatic patients.

STUDY DESIGN

Retrospective analysis.

METHODS

Medical records of patients from a quaternary care laryngology practice who have asthma were reviewed retrospectively. Subjects were divided into two groups determined by the particle size of their ICS, small or standard. Each patient only used one type of inhaler. All subjects had been seen in the office for dysphonia evaluation. Statistical analysis was performed on the collected data using χ2 analysis with Yate's Correction for categorical data and a student t-test for means. A P value of less than 0.05 was considered significant.

RESULTS

There was a significant difference in vocal fold atrophy rate between groups.

CONCLUSION

Routine use of standard particle size ICS is associated with more atrophy than small size ICS.

Clinical Practice Guideline: Hoarseness (Dysphonia) (Update)

Objective

This guideline provides evidence-based recommendations on treating patients who present with dysphonia, which is characterized by altered vocal quality, pitch, loudness, or vocal effort that impairs communication and/or quality of life. Dysphonia affects nearly one-third of the population at some point in its life. This guideline applies to all age groups evaluated in a setting where dysphonia would be identified or managed. It is intended for all clinicians who are likely to diagnose and treat patients with dysphonia.

Purpose

The primary purpose of this guideline is to improve the quality of care for patients with dysphonia, based on current best evidence. Expert consensus to fill evidence gaps, when used, is explicitly stated and supported with a detailed evidence profile for transparency. Specific objectives of the guideline are to reduce inappropriate variations in care, produce optimal health outcomes, and minimize harm. For this guideline update, the American Academy of Otolaryngology—Head and Neck Surgery Foundation selected a panel representing the fields of advanced practice nursing, bronchoesophagology, consumer advocacy, family medicine, geriatric medicine, internal medicine, laryngology, neurology, otolaryngology–head and neck surgery, pediatrics, professional voice, pulmonology, and speech-language pathology.

Action Statements

The guideline update group made strong recommendations for the following key action statements (KASs): (1) Clinicians should assess the patient with dysphonia by history and physical examination to identify factors where expedited laryngeal evaluation is indicated. These include, but are not limited to, recent surgical procedures involving the head, neck, or chest; recent endotracheal intubation; presence of concomitant neck mass; respiratory distress or stridor; history of tobacco abuse; and whether the patient is a professional voice user. (2) Clinicians should advocate voice therapy for patients with dysphonia from a cause amenable to voice therapy. The guideline update group made recommendations for the following KASs: (1) Clinicians should identify dysphonia in a patient with altered voice quality, pitch, loudness, or vocal effort that impairs communication or reduces quality of life (QOL). (2) Clinicians should assess the patient with dysphonia by history and physical examination for underlying causes of dysphonia and factors that modify management. (3) Clinicians should perform laryngoscopy, or refer to a clinician who can perform laryngoscopy, when dysphonia fails to resolve or improve within 4 weeks or irrespective of duration if a serious underlying cause is suspected. (4) Clinicians should perform diagnostic laryngoscopy, or refer to a clinician who can perform diagnostic laryngoscopy, before prescribing voice therapy and document/communicate the results to the speech-language pathologist (SLP). (5) Clinicians should advocate for surgery as a therapeutic option for patients with dysphonia with conditions amenable to surgical intervention, such as suspected malignancy, symptomatic benign vocal fold lesions that do not respond to conservative management, or glottic insufficiency. (6) Clinicians should offer, or refer to a clinician who can offer, botulinum toxin injections for the treatment of dysphonia caused by spasmodic dysphonia and other types of laryngeal dystonia. (7) Clinicians should inform patients with dysphonia about control/preventive measures. (8) Clinicians should document resolution, improvement or worsened symptoms of dysphonia, or change in QOL of patients with dysphonia after treatment or observation. The guideline update group made a strong recommendation against 1 action: (1) Clinicians should not routinely prescribe antibiotics to treat dysphonia. The guideline update group made recommendations against other actions: (1) Clinicians should not obtain computed tomography (CT) or magnetic resonance imaging (MRI) for patients with a primary voice complaint prior to visualization of the larynx. (2) Clinicians should not prescribe antireflux medications to treat isolated dysphonia, based on symptoms alone attributed to suspected gastroesophageal reflux disease (GERD) or laryngopharyngeal reflux (LPR), without visualization of the larynx. (3) Clinicians should not routinely prescribe corticosteroids for patients with dysphonia prior to visualization of the larynx. The policy level for the following recommendation about laryngoscopy at any time was an option: (1) Clinicians may perform diagnostic laryngoscopy at any time in a patient with dysphonia.

Voice Assessment After Treatment of Subacute and Chronic Cough With Inhaled Steroids

INTRODUCTION

Inhaled steroids are widely used for persistent cough treatment. Although the side effects of long-term inhaled steroids have been well described in the literature, their laryngeal side effects after short-term use have not yet been defined. The aim of this study was to evaluate the effect of 1 month application of inhaled steroid treatment on voice parameters in patients with subacute or chronic cough. Furthermore, the efficacy of inhaled steroids on cough was investigated, as well.

MATERIAL AND METHODS

This study included 46 patients (27 females and 19 males) with a persistent cough lasting at least 3 weeks and treated with inhaled steroids. All patients were examined by a pulmonologist and lung auscultation where a posteroanterior chest X-ray and spirometry were performed. The patients were also examined by an otolaryngologist. Anterior rhinoscopy, flexible fiberoptic nasopharyngoscopy, and laryngostroboscopy were performed. Also, the patients' acoustic voice analyses were performed and recorded using a multidimensional voice program. Cough symptom index (CSI) scores were used to evaluate the response to treatment. Patients with an underlying disease that was unresponsive to inhaled steroids were excluded from study. The 46 patients were administered inhaled budesonide 400 mcg twice a day, for 1 month, and their acoustic voice analyses were performed again at the end of the treatment. In addition, CSI scores were determined after stopping medication.

RESULTS

When pretreatment and posttreatment acoustic voice analysis parameters (Fo, Jita, Jitt, Shim, APQ, vAm, and NHR) were compared, statistically significant differences were detected for vAm (P = 0.001) and F0 (P0.003). After treatment with inhaled steroids, the CSI score reduced from 3 to 1 (median), and the difference was statistically significant.

CONCLUSIONS

Inhaled budesonide treatment in the proper dose seems to be an effective treatment for persistent cough, in the selected patient group. In addition, short-term budesonide application did not cause any negative effects on the voice parameters in these patients. These findings may be related to the steroid formulation used, the application method, and the duration of treatment. Further studies are needed on a larger group of patients with different formulations of inhaled steroids to clarify aforementioned issues.

Dry mouth as a novel indicator of hoarseness caused by inhalation therapy

OBJECTIVE

To investigate the influence of dry mouth on the incidence and severity of inhalation therapy-induced hoarseness.

METHODS

The volume of saliva secreted without stimulation was measured in patients with asthma or chronic obstructive pulmonary disease (COPD) who also answered a questionnaire on subjective ratings for hoarseness. The relationship between salivary secretion and hoarseness was analyzed by the Pearson correlation and multiple linear regression. The prediction accuracy of salivary secretion for the grade of hoarseness was evaluated using a receiver-operating characteristic (ROC) analysis.

RESULTS

A total of 232 patients participated in this study. The subjective rating score of hoarseness was negatively correlated with the volume of saliva secreted (r = -0.273, p < 0.001). A stepwise multiple linear regression analysis revealed that salivary secretion (p < 0.001) and the dose of fluticasone administered (p < 0.05) were significant variables for predicting hoarseness. The ROC analysis for predicting severe hoarseness by salivary secretion showed significant prediction accuracy (AUC = 0.690, 95% CI: 0.614-0.766, p < 0.001) and was higher in patients administered fluticasone (AUC = 0.732, 95% CI: 0.644-0.821, p < 0.001).

CONCLUSIONS

Hyposalivation is a significant prediction factor of hoarseness induced by inhaled corticosteroids (ICS). The prediction accuracy was higher in patients administered fluticasone than in those administered another inhalation drug. Although the pharmaceutical efficacy of fluticasone is high, patients with hyposalivation should be prescribed other inhalation drugs.

Risk factors of local oropharyngeal and laryngeal adverse effects from use of single inhaled corticosteroids and long-acting beta-agonists

BACKGROUND

Single inhaled corticosteroids and long-acting beta-agonists (ICS/LABA) are clinically effective and safe. However, if local oropharyngeal and laryngeal adverse effects (LOLAE) appear, adherence to the use of ICS is impaired. To minimize the development of adverse effects, it is essential to identify the underlying risk factors.

METHODS

The study included 481 asthmatic patients who were prescribed ICS/LABA for the first time in their life between January and September of 2010. Patients ranged in age from 14 to 86 years old and consisted of 281 never smokers and 200 smokers. All data were collected retrospectively by respirologists.

RESULTS

Seventy-three out of 481 patients suffered from one or more adverse effects, with 54 of these exhibiting LOLAE. Patients with LOLAE (51.4 ± 16.2 yrs) were significantly older than those without LOLAE (43.7 ± 15.9 yrs) (p = 0.0011) and were also prescribed a significantly higher dose of ICS. The pack-years of patients with LOLAE (2.1 ± 4.9) were significantly lower than those without LOLAE (6.0 ± 13.0) (p = 0.0087). The type of administered ICS was also significantly associated with a risk of developing LOLAE.

CONCLUSIONS

Our survey indicated that a greater age, a higher dose of ICS, and the type of ICS were potential risk factors of LOLAE. The identified factors should be considered in a clinical setting in order to prevent the development of LOLAE and provide optimal treatment to patients.

Age-dependent deterioration of peak inspiratory flow with two kinds of dry powder corticosteroid inhalers (Diskus and Turbuhaler) and relationships with asthma control

BACKGROUND

Inhaled corticosteroid (ICS) therapy has improved the quality of life (QOL) for many asthmatics and reduced mortality rates associated with asthma. However, some patients do not obtain therapeutic benefit despite satisfactory adherence.

OBJECTIVES

To determine whether asthmatic patients were using ICS devices appropriately, and to clarify relationships between these results and QOL.

SUBJECTS AND METHODS

We studied 100 adult asthmatics, divided into two groups: 50 patients consecutively registered as using Diskus (fluticasone; D-group) and 50 consecutively registered as using Turbuhaler (budesonide; T-group). We measured peak inspiratory flows (PIFs) using the In-Check Dial device. Subjects also completed the Asthma Control Test for evaluation of QOL.

RESULTS

In the D-group, no patients showed PIF below the optimal range (30-90 L/min), whereas 52% of patients had PIF≥91 L/min. In the T-group, 6% of patients showed PIF over the optimal range (60-90 L/min), and 44% had PIF≤59 L/min. When patients in the T-group were required to deliberately make a maximal inhalation, 14% still had PIF≤59 L/min. The proportion of patients with poor control was significantly greater in the T-group than in the D-group. According to univariate logistic regression analyses, low PIF tended to be associated with poor asthma control in the T-group. No significant correlation was found between PIF and age in the D-group, but PIF decreased significantly with age in the T-group.

CONCLUSIONS

Appropriate measures for patients in whom PIF has been judged as lower than optimal include adequate education for inhalation and/or changing to a different inhalation device. These measures should be kept in mind for elderly asthma patients in particular, where appropriate selection of a corticosteroid inhalation device in the early stages of therapy would also be important.

Gender-specific asthma treatment

Because genetic characteristics vary among subjects, the therapeutic effects of a certain drug differ among patients with the same disease. For this reason, special interest has focused on tailored treatments. Although it is well known that sex is genetically determined, little attention has been paid to sex differences in the clinical features and treatment of asthma. Females are more likely to suffer allergic asthma, to have difficulty controlling asthma symptoms, and to show adverse effects to drugs. As asthma symptoms show cyclic changes depending on female hormone levels in many women of child-bearing age, the use of contraceptives may specifically help to treat female patients with asthma such as those with perimenstrual asthma and severe asthma. Generally, testosterone seems to suppress asthma, and dehydroepiandrosterone (DHEA), a less virilizing androgen, may be effective for treating asthma. Evidence exists for a therapeutic and steroid-sparing effect of DHEA. However, further studies on the optimal dose and route of DHEA for each sex are needed. Monitoring of the serum DHEA-S level is necessary for patients with asthma on inhaled steroid treatment, and at minimum, replacement therapy for patients with a low level of DHEA may be helpful for treating their asthma.

Evidence for adverse phonatory change following an inhaled combination treatment

PURPOSE

Voice problems are reported as a frequent side effect of inhaled combination (IC) treatments. The purpose of this experimental study was to investigate whether IC treatments are detrimental to phonation. We hypothesized that IC treatment would significantly increase phonation threshold pressure (PTP) and perceived phonatory effort (PPE), whereas sham treatment would not.

METHOD

Fourteen healthy adults participated in a repeated-measures design in which they received IC and sham treatments in counterbalanced order. PTP and PPE were measured prior to treatments, immediately following treatments, and at 1 and 2 hr following treatments.

RESULTS

IC treatment increased PTP, but sham treatment did not. The increase in PTP was maintained for a 2 hr period following administration. PPE ratings were not significantly correlated with PTP.

CONCLUSIONS

IC treatments can have acute, adverse effects on phonation. Detrimental phonatory effects were elicited in participants with no self-reported voice problems. IC treatments are being increasingly prescribed across the lifespan. The current data increase our understanding of the nature of phonatory deterioration associated with IC treatment and lay the groundwork for increased research effort to develop IC treatments that effectively control respiratory disease while minimizing an adverse effect on phonation.

Clinical Practice Guideline: Hoarseness (Dysphonia)

Objective:

This guideline provides evidence-based recommendations on managing hoarseness (dysphonia), defined as a disorder characterized by altered vocal quality, pitch, loudness, or vocal effort that impairs communication or reduces voice-related quality of life (QOL). Hoarseness affects nearly one-third of the population at some point in their lives. This guideline applies to all age groups evaluated in a setting where hoarseness would be identified or managed. It is intended for all clinicians who are likely to diagnose and manage patients with hoarseness.

Purpose:

The primary purpose of this guideline is to improve diagnostic accuracy for hoarseness (dysphonia), reduce inappropriate antibiotic use, reduce inappropriate steroid use, reduce inappropriate use of anti-reflux medications, reduce inappropriate use of radiographic imaging, and promote appropriate use of laryngoscopy, voice therapy, and surgery. In creating this guideline the American Academy of Otolaryngology—Head and Neck Surgery Foundation selected a panel representing the fields of neurology, speech-language pathology, professional voice teaching, family medicine, pulmonology, geriatric medicine, nursing, internal medicine, otolaryngology–head and neck surgery, pediatrics, and consumers.

Results

The panel made strong recommendations that 1) the clinician should not routinely prescribe antibiotics to treat hoarseness and 2) the clinician should advocate voice therapy for patients diagnosed with hoarseness that reduces voice-related QOL. The panel made recommendations that 1) the clinician should diagnose hoarseness (dysphonia) in a patient with altered voice quality, pitch, loudness, or vocal effort that impairs communication or reduces voice-related QOL; 2) the clinician should assess the patient with hoarseness by history and/or physical examination for factors that modify management, such as one or more of the following: recent surgical procedures involving the neck or affecting the recurrent laryngeal nerve, recent endotracheal intubation, radiation treatment to the neck, a history of tobacco abuse, and occupation as a singer or vocal performer; 3) the clinician should visualize the patient's larynx, or refer the patient to a clinician who can visualize the larynx, when hoarseness fails to resolve by a maximum of three months after onset, or irrespective of duration if a serious underlying cause is suspected; 4) the clinician should not obtain computed tomography or magnetic resonance imaging of the patient with a primary complaint of hoarseness prior to visualizing the larynx; 5) the clinician should not prescribe anti-reflux medications for patients with hoarseness without signs or symptoms of gastroesophageal reflux disease; 6) the clinician should not routinely prescribe oral corticosteroids to treat hoarseness; 7) the clinician should visualize the larynx before prescribing voice therapy and document/communicate the results to the speech-language pathologist; and 8) the clinician should prescribe, or refer the patient to a clinician who can prescribe, botulinum toxin injections for the treatment of hoarseness caused by adductor spasmodic dysphonia. The panel offered as options that 1) the clinician may perform laryngoscopy at any time in a patient with hoarseness, or may refer the patient to a clinician who can visualize the larynx; 2) the clinician may prescribe anti-reflux medication for patients with hoarseness and signs of chronic laryngitis; and 3) the clinician may educate/counsel patients with hoarseness about control/preventive measures.

Disclaimer:

This clinical practice guideline is not intended as a sole source of guidance in managing hoarseness (dysphonia). Rather, it is designed to assist clinicians by providing an evidence-based framework for decision-making strategies. The guideline is not intended to replace clinical judgment or establish a protocol for all individuals with this condition, and may not provide the only appropriate approach to diagnosing and managing this problem.

Demographic data in asthma clinical trials: a systematic review with implications for generalizing trial findings and tackling health disparities

The prevalence of asthma, and the morbidity, adverse events, mortality and healthcare utilisation of asthmatic patients vary widely among racial/ethnic and other socio-demographic groups. Debates over the meanings of race and ethnicity and the strategic need to resolve health inequalities have prompted extensive recommendations for reporting and analyzing racial/ethnic and demographic information in clinical trials. We conducted a systematic review to determine the extent to which race/ethnicity, socio-economic status and other demographic variables are analyzed and reported in publications from randomized controlled trials of asthma interventions. Randomized controlled trials of inhaled corticosteroids and long-acting beta-agonists in asthmatic patients were identified by systematically searching 12 electronic bibliographic databases. We identified peer-reviewed papers reporting 87 relevant trials published during 1985-2006, from which we extracted data on patients' race/ethnicity, ancestry, gender, socio-economic variables and geographical attributes. The proportion of the papers reporting the race/ethnicity of their participants was lower than would be expected by chance and has recently declined. None of the papers included race/ethnicity or gender in statistical analyses or reported socio-economic variables, ancestry, or genetic data for their participants, and few discussed the generalizability of their findings. The frequency of reporting race/ethnicity was statistically significantly lower in trials conducted in the UK than in the US, but 23 of the 87 papers did not identify countries. Despite extensive recommendations in the literature, guidance from health agencies on analyzing and reporting demographic data in clinical trials still appears inconsistent and vague. There remains a need to improve guidance on the representation and analysis of minority populations in asthma clinical trials, in order to encourage transparent reporting of population selection, analysis approaches, and trial generalizability. To assist this process, asthma clinical trials should be based on clear hypotheses that link both to existing demographic evidence and to demographic healthcare goals.
