RESUMO
BACKGROUND: Uncomplicated urinary tract infections (uUTIs) are one of the most common community-acquired infections, particularly among women. Common symptoms of UTI include dysuria, urinary urgency and increased frequency, and lower abdominal pain. With appropriate treatment, symptoms may resolve in a few days. However, there is a lack of research on the emotional impact of this disease. We conducted a qualitative, interview-based study to gain a greater understanding of the emotional impact of uUTIs in women in China and Japan. METHODS: A qualitative, exploratory, in-depth, interview-based study was conducted between 19 November 2020 and 25 February 2021. Women aged ≥ 18 years who experienced ≥ 1 uUTI and received antibiotic treatment in the past year were eligible for inclusion. Participants must have experienced ≥ 1 of the following symptoms during a uUTI episode: urinary urgency, frequency, dysuria, or lower abdominal/suprapubic pain. Participants who reported back pain or fever (indicative of complicated UTI) were excluded. Participants with recurrent or sporadic UTIs were included, with specific screening criteria used to ensure capture of both groups. Following a screening call, a structured, in-depth telephone interview (~ 30 min in duration) was conducted by three female external moderators trained in qualitative interviewing, assisted by an interview guide. Interviews were analysed individually and thematically, with the results presented within the identified themes. RESULTS: A total of 65 women with uUTI completed the in-depth telephone interview: 40 (62%) from China and 25 (38%) from Japan. Participants reported that the symptoms of uUTI affected multiple aspects of their lives, and described feelings of embarrassment, frustration, guilt, dread, and loneliness associated with symptoms that interfered with relationships, work and daily activities, and sleep. Participants reported seeking healthcare from several different points of contact, from local pharmacies to hospitals. CONCLUSIONS: Our analysis highlights the profound emotional impact of uUTIs in women in China and Japan, and the journey these participants take before their initial interaction with a healthcare professional. These insights emphasise the need to better understand the full impact of uUTI, and the role of healthcare professionals in improved patient education and support.

BACKGROUND: While many studies address the clinical management of participants with uncomplicated urinary tract infection (uUTI), the emotional impact of uUTIs has been investigated less often. The aim of this qualitative study was to understand the emotional experience of women with uUTIs. METHODS: This was a qualitative, exploratory, in-depth interview-based study conducted among women in the United States (US) and Germany. Women aged ≥ 18 years with at least one uUTI treated with antibiotics in the past year were recruited through a patient community panel and physician referrals. Participants were recruited using purposive sampling to include an equal split of those with 1 or ≥ 2 antibiotics, and an equal split of those treated for a single or recurrent uUTIs (≥ 2 uUTIs in the past year). A structured telephone interview included questions about symptoms, diagnosis, treatment, and retreatment (if any). Each participant was queried about her emotions and the impact of the uUTI on life activities. Thematic analysis of responses was carried out to identify common themes. RESULTS: A total of 65 participants completed the interview, 40 (61.5%) from the US and 25 (38.5%) from Germany. Major themes that emerged from the analyses included (1) a wide range of negative emotions were experienced due to uUTI symptoms, interference with activities of daily life, and effects on relationships and sleep; (2) varied emotions and understanding related to uUTI treatment and management approaches; (3) treatment failure caused frustration, worry, and anger; and (4) the prospect of recurrent uUTIs provoked dread and helplessness. CONCLUSION: Our research uncovered emotions of helplessness and dread experienced by women in the context of uUTI clinical treatment failure and recurrent uUTIs. Knowing patients' perspectives on UTI management will help guide the development of patient education and improve shared decision-making.

BACKGROUND: Uncomplicated urinary tract infection (uUTI) is predominantly caused by Escherichia coli, which has increasing antimicrobial resistance (AMR) at the United States (US)-community level. As uUTI is often treated empirically, assessing AMR is challenging, and there are limited contemporary data characterizing period prevalence in the US. METHODS: This was a retrospective study of AMR using Becton, Dickinson and Company Insights Research Database (Franklin Lakes, New Jersey, US) data collected 2011-2019. Thirty-day, nonduplicate Escherichia coli urine isolates from US female outpatients (agedâ ≥12 years) were included. Isolates were evaluated for nonsusceptibility (intermediate/resistant) to trimethoprim-sulfamethoxazole, fluoroquinolones, or nitrofurantoin, and assessed for extended-spectrum ß-lactamase production (ESBL+) and for ≥2 or ≥3 drug-resistance phenotypes. Generalized estimating equations were used to model AMR trends over time and by US census region. RESULTS: Among 1 513 882 E. coli isolates, the overall prevalence of isolates nonsusceptible to trimethoprim-sulfamethoxazole, fluoroquinolones, and nitrofurantoin was 25.4%, 21.1%, and 3.8%, respectively. Among the isolates, 6.4% were ESBL+, 14.4% had ≥2 drug-resistance phenotypes, and 3.8% had ≥3. Modeling demonstrated a relative average yearly increase of 7.7% (95% confidence interval [CI], 7.2-8.2%) for ESBL+ isolates and 2.7% (95% CI, 2.2-3.2%) for ≥3 drug-phenotypes (both Pâ <â .0001). Modeling also demonstrated significant variation in AMR prevalence between US census regions (Pâ <â .001). CONCLUSIONS: Period prevalence of AMR among US outpatient urine-isolated E. coli was high, and for multidrug-resistance phenotypes increased during the study period with significant variation between census regions. Knowledge of regional AMR rates helps inform empiric treatment of community-onset uUTI and highlights the AMR burden to physicians.

Antibiotic resistance is a threat to public health, and uncomplicated urinary tract infections (uUTIs) are an example of this concern. This systematic review (International Prospective Register of Systematic Reviews [PROSPERO] ID: CRD42020156674) is the first to determine the prevalence of Escherichia coli resistance to fluoroquinolones in women with community-acquired uUTI. PubMed and Embase searches were conducted; 38 studies fulfilled eligibility criteria and were included in the systematic review. Within Europe, ciprofloxacin resistance in E. coli isolates varied between countries and increased in some from 2006 to 2008 and 2014 to 2016, specifically in the United Kingdom (0.5% to 15.3%), Germany (8.7% to 15.1%), and Spain (22.9% to 30.8%), although methodologies and settings were often not comparable. In Asia, there was a substantial increase in ciprofloxacin resistance during 2008 to 2014 from 25% to more than 40%. In North America, resistance to ciprofloxacin also increased between 2008 and 2017, from 4% to 12%. Data exploring different age groups did not show a consistent relationship with resistance, whereas two studies found that fluoroquinolone resistance was higher in postmenopausal women than premenopausal women. One study indicated a link between fluoroquinolone resistance and uUTI recurrence. These findings may have implications for the empirical treatment of uUTI with fluoroquinolones globally, but more data are needed to fully understand regional situations and impact patient management.

INTRODUCTION: Urinary tract infections (UTIs) caused by antimicrobial-resistant Enterobacterales are a global health threat. There are limited surveillance data available to characterize the prevalence of antimicrobial resistance among outpatients in the United States (US). METHODS: This retrospective cohort (database) study investigated co-resistance among Escherichia coli and Klebsiella pneumoniae urinary isolates from US female outpatients aged ≥ 12 years with presumed uncomplicated UTI (uUTI), ≥ 3 months of data (2011-2019), and antimicrobial susceptibility testing results. Eligible isolates were the first urinary E. coli or K. pneumoniae isolate per patient collected within 30 days; classified as not susceptible (NS) if antimicrobial susceptibility testing results were intermediate or resistant to each antibiotic tested. Four resistance phenotypes were identified: NS to fluoroquinolones (FQ), trimethoprim/sulfamethoxazole (SXT), nitrofurantoin (NTF), and extended-spectrum ß-lactamase+/third-generation cephalosporin (ESBL+/3GC NS). Co-resistance phenotypes included all possible combinations of resistance to ≥ 2 drug classes. RESULTS: Of 1,513,882 E. coli isolates and 250,719 K. pneumoniae isolates, 856,918 and 187,459 isolates with ≥ 1 resistance phenotype were included in the analysis, respectively. The most common resistance phenotypes were SXT NS for the E. coli isolates (44.8%) and NTF NS for the K. pneumoniae isolates (75.5%), while ESBL+/3GC NS comprised 11.2 and 5.9%, respectively. Among ESBL+/3GC NS E. coli isolates, 72.4, 56.7, and 46.6% were co-resistant to FQ, SXT, and FQ + SXT, respectively. For ESBL+/3GC NS K. pneumoniae isolates, 65.7 and 45.7% were co-resistant to SXT and FQ + SXT. CONCLUSION: Both species exhibited high rates of co-resistance, emphasizing the need to raise awareness of co-resistance and of the unmet need for effective treatment options for uUTI.
RESUMO
OBJECTIVE: To assess the relative likelihood of antimicrobial resistance (AMR) and multi-drug resistance (MDR) among E. coli isolates from outpatients with recurrent versus non-recurrent uncomplicated urinary tract infection (uUTI). METHODS: In this retrospective observational US cohort study, female outpatients (≥12 years) with uUTI, positive E. coli culture, and treated with ≥1 oral antibiotic within ±5 days of diagnosis were grouped into recurrent and non-recurrent uUTI cohorts per their UTI history (past 12 months). AMR to specific drug classes was evaluated at index. Univariable and multivariable logistic regression models estimated the likelihood of not-susceptible E. coli isolates (AMR/MDR) among patients with recurrent uUTI versus non-recurrent uUTI. RESULTS: Recurrent (Nâ¯=â¯12,234) and non-recurrent (Nâ¯=â¯68,033) uUTI cohorts had similar distributions (race, ethnicity, region). Patients with recurrent uUTI had a higher prevalence of E. coli resistance to trimethoprim-sulfamethoxazole (21.8% vs 18.7%) and fluoroquinolones (14.2% vs 8.6%), and more isolates were extended-spectrum ß-lactamase-producing (5.9% vs 4.1%) compared to non-recurrent uUTI patients. Patients with recurrent uUTI had a higher likelihood (odds ratio [95% confidence interval]) of any AMR (1.28 [1.22-1.34]), single drug-class resistance (1.18 [1.12-1.24]), and resistance to 2 (1.53 [1.41-1.67]) or ≥3 drug classes (1.70 [1.48-1.96]) (all Pâ¯<.001). CONCLUSION: This study delineated the likelihood of AMR and MDR among E. coli isolates from patients with recurrent versus non-recurrent uUTI. While some treatment guidelines support empiric therapy in recurrent uUTI, the increased likelihood of resistance among these patients suggests that culture and susceptibility testing should be undertaken to inform recurrent uUTI treatment.

BACKGROUND: Antimicrobial resistance research in uncomplicated urinary tract infection typically focuses on the main causative pathogen, Escherichia coli; however, little is known about the antimicrobial resistance burden of Klebsiella species, which can also cause uncomplicated urinary tract infections. This retrospective cohort study assessed the prevalence and geographic distribution of antimicrobial resistance among Klebsiella species and antimicrobial resistance trends for K. pneumoniae in the United States (2011-2019). METHODS: K. pneumoniae and K. oxytoca urine isolates (30-day, non-duplicate) among female outpatients (aged ≥ 12 years) with presumed uUTI at 304 centers in the United States were classified by resistance phenotype(s): not susceptible to nitrofurantoin, trimethoprim/sulfamethoxazole, or fluoroquinolone, extended-spectrum ß-lactamase-positive/not susceptible; and multidrug-resistant based on ≥ 2 and ≥ 3 resistance phenotypes. Antimicrobial resistance prevalence by census division and age, as well as antimicrobial resistance trends over time for Klebsiella species, were assessed using generalized estimating equations. RESULTS: 270,552 Klebsiella species isolates were evaluated (250,719 K. pneumoniae; 19,833 K. oxytoca). The most frequent resistance phenotypes in 2019 were nitrofurantoin not susceptible (Klebsiella species: 54.0%; K. pneumoniae: 57.3%; K. oxytoca: 15.1%) and trimethoprim/sulfamethoxazole not susceptible (Klebsiella species: 10.4%; K. pneumoniae: 10.6%; K. oxytoca: 8.6%). Extended-spectrum ß-lactamase-positive/not susceptible prevalence was 5.4%, 5.3%, and 6.8%, respectively. K. pneumoniae resistance phenotype prevalence varied (p < 0.0001) geographically and by age, and increased over time (except for the nitrofurantoin not susceptible phenotype, which was stable and > 50% throughout). CONCLUSIONS: There is a high antimicrobial resistance prevalence and increasing antimicrobial resistance trends among K. pneumoniae isolates from female outpatients in the United States with presumed uncomplicated urinary tract infection. Awareness of K. pneumoniae antimicrobial resistance helps to optimize empiric uncomplicated urinary tract infection treatment.

Background: Current US Food and Administration (FDA) guidance recommends that the primary efficacy endpoint for uncomplicated urinary tract infection (uUTI) clinical trials be a composite of clinical and microbiological responses. We applied these criteria to a previous clinical trial to determine the impact on treatment outcomes. Methods: We conducted a patient-level reanalysis of a randomized clinical trial of nitrofurantoin versus fosfomycin for treatment of uUTI in nonpregnant adult women. Women were included in the reanalysis if they had 2 or more signs/symptoms of uUTI and a single bacterial species isolated from baseline urine culture at ≥105â colony-forming units (CFU)/mL. The applied primary efficacy endpoint-therapeutic response-required both clinical resolution of signs/symptoms and reduction of the infecting bacterial pathogen to <103â CFU/mL at day 14 post-treatment completion. Results: Two hundred eleven of 513 (41%) patients were eligible for inclusion in the reanalysis. Among these patients, 74% (76/103) and 69% (75/108) in the nitrofurantoin and fosfomycin groups, respectively, achieved clinical resolution by day 14. Similarly, 70% (72/103) and 67% (72/108) in each group achieved microbiological success at day 14. As such, 59% (61/103) and 57% (62/108) of women in each group met the primary efficacy endpoint-therapeutic success-at day 14. In comparison, 75% and 66% of patients in each group achieved clinical resolution at day 14 in the initial clinical trial. Conclusions: Applying current FDA guidance resulted in lower composite efficacy rates than clinical resolution alone as observed in the initial clinical trial. This may limit the ability to compare antibiotic treatment effects between historical and future clinical trials.
RESUMO
Real-world data were collected to examine antimicrobial resistance (AMR) prevalence, treatment patterns, and clinical outcomes among female patients with uncomplicated urinary tract infection (uUTI) in Germany. Data were from a retrospective physician-based chart review completed by physicians treating patients with uUTI. Non-pregnant women aged ≥ 12 years, with a uUTI diagnosis, an E. coli-positive urine culture between January 2017-December 2019, and susceptibility test results for ≥ 4 drug classes were eligible. Patients were stratified into three cohorts by drug class susceptibility: susceptible to all (SUS), resistant to one or two drug classes (DR1/2), and resistant to ≥ 3 (MDR) drug classes tested. Among 386 eligible patients [SUS (67.1%); DR1/2 (29.0%); MDR (3.9%)], AMR prevalence was highest for FMIs (18.3%) and lowest for fluoroquinolones (5.2%). The most prescribed drugs were fosfomycin in SUS (44.0%), DR1/2 (41.4%), and fluoroquinolones in MDR (40.0%). Treatment for uUTI failed for 8.8% of patients; failure was more likely in MDR versus SUS [adjusted odds ratio [95% CI] = 4.21 [1.14-1.50]; P = 0.031); incidence of recurrent infection in the 6-months post-index period was higher in DR1/2 versus SUS. These findings may have implications for empiric prescribing, suggesting an unmet need for new treatments.

BACKGROUND: Increasing prevalence of antimicrobial resistance (AMR), including multidrug resistance (MDR), among Escherichia coli (E. coli) makes treatment of uncomplicated urinary tract infection (uUTI) difficult. We assessed risk factors for fluoroquinolone (FQ)-not-susceptible (NS) and MDR E. coli among US female outpatients. METHODS: This retrospective cohort study utilized data from female outpatients aged ≥ 12 years with E. coli positive urine culture and oral antimicrobial prescription ± 1 day from index. We assessed patient-level factors within 90 and 91-360 days prior to index as predictors of FQ NS (intermediate/resistant) and MDR (NS to ≥ 1 drug across ≥ 3 classes) E. coli: age, prior oral antimicrobial dispensing, prior AMR phenotypes, prior urine culture, and prior hospitalization. RESULTS: Among 1,858 outpatients with urine-isolated E. coli, 369 (19.9%) had FQ NS and 59 (3.2%) had MDR isolates. After multivariable adjustment, independent risk factors (p < 0.03) for FQ NS E. coli were older age, prior FQ NS isolates, prior dispensing of FQ, and dispensing of any oral antibiotic. Independent risk factors (p < 0.02) for MDR were prior extended-spectrum ß-lactamase-producing isolates (ESBL+), prior FQ dispensing, and prior oral antibiotic dispensing. CONCLUSIONS: In women with uUTI due to E. coli, prior dispensing of FQ or any oral antibiotic within 90 days predicted FQ NS and MDR urine E. coli. Prior urine culture with FQ NS isolates and older age were predictive of FQ NS E. coli. Prior ESBL+ was predictive of MDR E. coli. These data could help identify patients at risk for AMR E. coli and inform empiric prescribing.

Background: Antimicrobial resistance is an urgent global healthcare concern. Beyond carbapenems as broad-spectrum, often 'last resort' antibiotics, oral penem antibiotics currently are approved only in Japan and India, used for the treatment of indications including urinary tract infections (UTIs). Exploring oral penem use to better understand the impact of antibiotic resistance on public health would help inform the management of infectious diseases, including UTIs. Scoping Review Methodology: This scoping review investigated the impact of faropenem and other oral penems on Enterobacterales infection treatment and evaluated evidence for faropenem resistance and cross-resistance to carbapenems. PubMed, Embase, J-STAGE and CiNii were searched for relevant English- or Japanese-language articles published between 1 January 1996 and 6 August 2021. Key Findings: From 705 unique publications, 29 eligible articles were included (16 in vitro studies; 10 clinical trials; 2 in vitro and in vivo studies; and 1 retrospective medical chart review). Limited evidence described faropenem to treat infectious disease; only four randomized clinical trials were identified. Faropenem dosing regimens varied broadly within and between indications. One study indicated potential dependence of penem efficacy on underlying antibiotic resistance mechanisms, while several studies reported UTI persistence or recurrence after faropenem treatment. In vitro MIC data suggested some potential bacterial resistance to faropenem, while limited clinical data showed resistance emergence after faropenem treatment. Preliminary in vitro evidence suggested faropenem resistance might foster cross-resistance to carbapenems. Overall, very limited clinical evidence describes faropenem for treating infectious diseases. Preclinical and clinical research investment and dedicated community surveillance monitoring is crucial for understanding faropenem treatment patterns, resistance and potential cross-resistance to carbapenems.
RESUMO
Background: Increasing antimicrobial resistance makes treating uncomplicated urinary tract infections (uUTIs) difficult. We compared whether adverse short-term outcomes among US female patients were more common when initial antimicrobial therapy did not cover the causative uropathogen. Methods: This retrospective cohort study used data from female outpatients aged ≥12â years, with a positive urine culture and dispensing of an oral antibiotic ±1â day from index culture. Isolate susceptibility to the antimicrobial initially dispensed, patient age, and history of antimicrobial exposure, resistance, and all-cause hospitalization within 12â months of index culture were evaluated for associations with adverse outcomes during 28-day follow up. Outcomes assessed were new antimicrobial dispensing, all-cause hospitalization, and all-cause outpatient emergency department/clinic visits. Results: Of 2366 uUTIs, 1908 (80.6%) were caused by isolates susceptible and 458 (19.4%) by isolates not susceptible (intermediate/resistant) to initial antimicrobial treatment. Within 28â days, patients with episodes caused by not susceptible isolates were 60% more likely to receive a new antimicrobial versus episodes with susceptible isolates (29.0% vs 18.1%; 95% confidence interval, 1.3-2.1; P < .0001). Other variables associated with new antibiotic dispenses within 28â days were older age, prior antimicrobial exposure, or prior nitrofurantoin-not-susceptible uropathogens (P < .05). Older age, prior antimicrobial-resistant urine isolates, and prior hospitalization were associated with all-cause hospitalization (P < .05). Prior fluoroquinolone-not-susceptible isolates or oral antibiotic dispensing within 12â months of index culture were associated with subsequent all-cause outpatient visits (P < .05). Conclusions: New antimicrobial dispensing within the 28-day follow-up period was associated with uUTIs where the uropathogen was not susceptible to initial antimicrobial treatment. Older age and prior antimicrobial exposure, resistance, and hospitalization also identified patients at risk of adverse outcomes.
RESUMO
BACKGROUND: In China, the prevalence of allergic rhinitis (AR) and asthma has increased in the past decade. As these two diseases frequently coexist, the Asia-Pacific Survey of Physicians on Asthma and Allergic Rhinitis (ASPAIR) study aimed to assess physicians' beliefs and treatment patterns of coexistent asthma-AR across six Asian countries. This analysis presents the results from China. METHODS: The 200 hospital-based general physicians and pediatricians were interviewed from five cities in China. Physicians were questioned in-person about their knowledge, beliefs and management practices for patients with coexistent asthma-AR. RESULTS: Approximately 70% of the physicians interviewed routinely evaluated their patients with asthma or AR for signs of coexistent disease. While the majority of physicians (>90% of physicians) recognized the increased burden of coexistent asthma-AR vs. one condition alone and that coexistent disease requires additional treatment, most physicians (96%) also believed that patients with coexistent asthma-AR were well managed if either condition alone improved. Similarly, although 71% of physicians selected a combination of intranasal and inhaled corticosteroids as their preferred treatment for coexistent asthma-AR, in line with treatment guidelines, two fifths of physicians indicated that treatment for coexistent disease requires too much medication and that their patients prefer oral medications and a third of physicians believed that corticosteroids should be delayed in children. CONCLUSIONS: This survey demonstrates that physicians interviewed in China have a broad understanding of coexistent asthma-AR and its impact on patients. A holistic approach to patient management with informed decisions regarding patients' overall treatment will benefit patients who suffer from coexistent disease.

BACKGROUND: Underdiagnosis and undertreatment of allergic rhinitis (AR) in patients with asthma can worsen treatment outcomes. There is limited evidence of clinical practices for management of coexistent AR-asthma in Thailand. METHODS: A multicountry, cross-sectional study (Asia-pacific Survey of Physicians on Asthma and allergic Rhinitis) to evaluate physician perceptions and management practices related to AR-asthma overlap in 6 Asian countries was conducted. For Thailand specifically, AR-asthma linkage questionnaires were developed and translated to Thailaland. General physicians (GPs) or pediatricians, randomly selected from hospitals in urban cities, routinely treating >10 asthma patients/month were interviewed. Here we present the results for Thailand. RESULTS: Two hundred physicians (100 GPs and 100 pediatricians), of whom 70% worked in government hospitals, were interviewed. In their experience, 50% of asthma patients had AR and 28% of AR patients had asthma. Among diagnosed asthma patients, 65% of physicians routinely asked for any AR symptoms at every visit. Among diagnosed AR patients, 63% of physicians routinely asked for any asthma symptoms at every visit. In patients with coexisting AR-asthma, 91% of physicians treated both diseases simultaneously, while 6% of physicians treated asthma as a chronic disease but managed AR symptomatically. The most preferred treatment options for patients with AR-asthma were inhaled corticosteroids with intranasal steroids (46% in GPs, 71% in pediatricians). CONCLUSION: The physicians interviewed in Thailand are aware about coexistent asthma-AR. There is a need to increase the awareness further for coexistent AR-asthma and to educate nonspecialist physicians in the proper management of AR-asthma patients.
RESUMO
Mild asthma is present in 50-75% of patients with asthma and is defined by the Global Initiative for Asthma as asthma that can be well controlled with low-intensity treatments (Steps 1 and 2). Despite this definition, 'mild' asthma is often not well controlled in reality, and can have a significant impact on an individual's symptom burden and quality of life. We performed a PubMed literature search to investigate the burden of 'mild' asthma in the lives of patients, including future risk and asthma control, and the current management strategies. While clinical guidelines recommend long-term, daily, low-dose inhaled corticosteroids (ICS) for 'mild' asthma, published data suggest that ICS are often under-prescribed or used intermittently as symptoms arise. Furthermore, patients and physicians tend to overestimate disease control, impacting the accuracy of diagnosing 'mild asthma' and subsequent management. This disconnect may be amplified by miscommunication between patients and physicians, limited objective assessment of control, and differences in guidelines. As with moderate and severe asthma, current evidence supports early initiation of regular ICS in 'mild' asthma to address the underlying inflammation, achieve symptom control and reduce risk of exacerbations. Adherence to ICS treatment is key and can be improved by educating both patients and healthcare professionals. The results of this literature search challenge the term 'mild' asthma and suggest strategies to improve the proactive management of the disease to enable patients to live symptom-free.

Exercise-induced bronchoconstriction (EIB) can occur in individuals with and without asthma, and is prevalent among athletes of all levels. In patients with asthma, symptoms of EIB significantly increase the proportion reporting feelings of fearfulness, frustration, isolation, depression and embarrassment compared with those without symptoms. EIB can also prevent patients with asthma from participating in exercise and negatively impact their quality of life. Diagnosis of EIB is based on symptoms and spirometry or bronchial provocation tests; owing to low awareness of EIB and lack of simple, standardised diagnostic methods, under-diagnosis and mis-diagnosis of EIB are common. To improve the rates of diagnosis of EIB in primary care, validated and widely accepted symptom-based questionnaires are needed that can accurately replicate the current diagnostic standards (forced expiratory volume in 1 s reductions observed following exercise or bronchoprovocation challenge) in patients with and without asthma. In patients without asthma, EIB can be managed by various non-pharmacological methods and the use of pre-exercise short-acting ß2-agonists (SABAs). In patients with asthma, EIB is often associated with poor asthma control but can also occur in individuals who have good control when not exercising. Inhaled corticosteroids are recommended when asthma control is suboptimal; however, pre-exercise SABAs are also widely used and are recommended as the first-line therapy. This review describes the burden, key features, diagnosis and current treatment approaches for EIB in patients with and without asthma and serves as a call to action for family physicians to be aware of EIB and consider it as a potential diagnosis.

BACKGROUND: Asthma and allergic rhinitis (AR) frequently coexist, and having both asthma and AR is associated with uncontrolled asthma and a heavier disease burden. The Asia-Pacific Survey of Physicians on Asthma and Allergic Rhinitis (ASPAIR) aimed to assess physicians' perceptions and their management practices for patients with coexistent disease. MATERIALS AND METHODS: A total of 1,204 general physicians and pediatricians from six countries in Asia, who routinely treat asthma patients, were interviewed in-person. Physicians were questioned about their attitudes and beliefs of coexistent asthma-AR, how they diagnose and treat patients, and their knowledge of international guideline recommendations. RESULTS: Physicians reported that 45% of their patients with asthma have coexistent AR and 37% of their patients with AR have coexistent asthma. Most physicians (77%) agreed that coexistent asthma-AR is a genuine condition and that patients suffer worse symptoms with both the conditions vs one alone (86%). Although nearly all agreed that both asthma and AR should be treated (91%) and that intranasal (INS) and inhaled corticosteroids (ICS) could be given concurrently to these patients, 40% also thought that treating both conditions effectively at the same time is difficult, and approximately a quarter believed that corticosteroid therapy should be delayed in children for both asthma and AR. While there was universal recognition and acceptance that guidelines provide sufficient information for treating uncontrolled coexistent disease (≥80% physicians in all countries), physicians revealed that 41% of their asthma patients are treated with short-acting rescue medications alone, and only 47% responded that treatment with concurrent INS and ICS, as recommended in the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines, was their preferred treatment for coexistent disease. CONCLUSION: The ASPAIR survey demonstrates a widespread acceptance of coexistent asthma-AR, and the associated burden, but highlights the need for increased healthcare practitioner communication and awareness to improve appropriate treatment and management of these coexistent conditions.
RESUMO
INTRODUCTION: Spacers offer a multitude of benefits by reducing the requirement to coordinate inhalation with actuation and improving inhaler technique in patients using a pressurized metered dose inhaler (pMDI). Spacers improve drug targeting by retaining within the spacer large particles normally deposited in the oropharynx, and by creating a prolonged aerosol cloud of fine particles to give the user increased time to inhale after actuation. This is particularly important in young children and the elderly to effectively deliver medication to the airways. AREAS COVERED: By investigating the history and features of spacers, we demonstrate that the advantages of using spacers far outweigh their limitations. We also discuss the optimal characteristics of spacers in terms of shape, volume, presence of valve and static charge, and present a detailed discussion of the VENTOLIN™ Mini Spacer. EXPERT OPINION: Generally, the shape and size of spacers makes them inherently inconvenient. Consideration of human factors and modern design may make them more attractive to patients. However, the incentive to use spacers should be their ability to help patients correctly use inhaled medications delivered by pMDIs. Understanding of these principles through education is key to their acceptance by patients.
