Analysis of the influenza A (H1N1) 2009 pandemic infection in Japanese asthmatic patients: using a questionnaire-based survey. Allergol Int 2014; 63:67-74. [PMID: 24457814 DOI: 10.2332/allergolint.13-oa-0609] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2013] [Accepted: 09/09/2013] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Influenza infection is known to be an exacerbating factor in the control of asthma, therfore its prevention is critical in managing asthma. The aim of this study was to investigate the influenza A H1N1 2009 pandemic virus (H1N1 pdm09) infection in adult asthmatic patients. METHODS Data were obtained from a questionnaire-based survey of asthmatic patients conducted from September to October 2010 in Niigata Prefecture. Patient background, H1N1 pdm09 infection, vaccination status, and asthma exacerbation due to influenza infection were analyzed. RESULTS In total, 2,555 cases were analyzed. The incidence of the infection was 6.7% (95% confidence interval [CI]: 5.7-7.6), and the rate of vaccination was 63.9% (95% CI: 62.1-65.8). The odds ratio (OR) for vaccination against the infection among adult patients and younger patients (≤ the median age) were 0.61 (95% CI: 0.45-0.84) and 0.62 (95% CI: 0.42-0.90), respectively. However, OR among the older patient (> median age) were 1.38 (95%CI: 0.66-2.89). The rate of infection-induced asthma exacerbation was 23.2% (95% CI: 18.6-29.6), and the OR for vaccination against the infection-induced asthma exacerbation was 1.42 (95% CI: 0.69-2.92). CONCLUSIONS The effectiveness of the vaccination against the H1N1 pdm09 virus was confirmed during the first pandemic season, but it was limited. Further investigation on H1N1 pdm09 virus infection in asthmatics will be required.

The Asthma Control Test, Japanese version (ACT-J) as a predictor of Global Initiative for Asthma (GINA) guideline-defined asthma control: analysis of a questionnaire-based survey. Allergol Int 2013; 62:323-330. [PMID: 23793506 DOI: 10.2332/allergolint.13-oa-0535] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2013] [Accepted: 02/19/2013] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND The 2006 Global Initiative for Asthma (GINA 2006) guidelines emphasize the importance of evaluating the control rather than the severity of asthma. The Asthma Control Test (ACT) is well known to be an excellent tool for evaluating asthma control in the clinical setting. This study aimed to evaluate the ACT, Japanese version (ACT-J) as a predictor of asthma control as defined by the GINA 2006 guidelines in actual clinical practice. METHODS A cross-sectional analysis comparing the ACT-J score and GINA classification of asthma control among 419 patients of primary care physicians and specialists was performed using the data from a 2010 questionnaire-based survey conducted by the Niigata Asthma Treatment Study Group. RESULTS The optimal cut-off point of the ACT-J score for predicting GINA-defined asthma control was 23, with ACT-J scores of ≥23 and ≤22 predicting controlled and uncontrolled asthma with area under the receiver operating characteristics curve values of 0.76 [95% confidence interval (CI): 0.72-0.81] and 0.93 [95% CI: 0.90-0.97], respectively. CONCLUSIONS ACT scores of ≥23 and ≤22 are useful for identifying patients with controlled and uncontrolled asthma, respectively, as defined by GINA 2006, and the latter is more strongly predictive than the former. The reason for the higher cut-off point of the ACT-J relative to other versions of the ACT is unclear and warrants further investigation.

Abstract
BACKGROUND The Asthma Control Test (ACT) is frequently used for the evaluation of asthma control in clinical care setting because it does not require the use of pulmonary function tests, which can be difficult for general practitioners to use. However, few large-scale studies have investigated the efficacy of the Japanese version ACT (J-ACT) in actual use during clinical care. METHODS The aim of this study was to analyze the efficacy of the J-ACT in a clinical care setting. Using data from a 2008 questionnaire survey including the J-ACT by the Niigata Asthma Treatment Study Group, we compared the ACT scores of 2233 patients with respect to multiple parameters, including the severity by Japanese Society of Allergology and the attack frequency. Using the definition of asthma control partially referred to Global Initiative for Asthma (GINA) guidelines from the survey data, the accuracy screening and determination of optimal ACT cutpoints were performed by retrospective analysis. RESULTS Cronbach's α for the J-ACT was 0.785. Patients with more severe asthma and more frequent asthma attacks had lower ACT scores than did patients with less severe, less frequent attacks. The optimal ACT cutpoints were 24 for the controlled asthma and 20 for the uncontrolled asthma. CONCLUSIONS Our study, the first large-scale investigation of the efficacy of the J-ACT, determined that this evaluation tool is highly efficacious in establishing the level of asthma control. However, the determination of accurate cutpoints for the J-ACT will require more clear definitions of asthma control in future prospective studies.

Abstract
BACKGROUND Although the association between asthma control and body mass index (BMI) has been thoroughly investigated, most of this work has focused on the influence on asthma incidence or the effect of obesity on asthma control. To date, there have been no published studies on the influence of underweight on asthma control. METHODS The aim of this study was to investigate the influence of underweight, as defined by the Japan Society for the Study of Obesity (JASSO), on asthma control in Japanese asthmatic patients. Using data from questionnaire surveys administered by the Niigata Asthma Treatment Study Group, we compared asthma control, as measured by the Asthma Control Test (ACT), between a normal weight group (18.5kg/m2 =< BMI < 25kg/m2) and an underweight group (BMI < 18.5kg/m2). RESULTS Of the asthmatic patients who completed the 2008 and 2010 surveys, 1464 and 1260 cases were classified as being in the normal weight group, and 174 and 155 cases were classified as being in the underweight group. The ACT score (median, [interquartile range]) in the underweight group in 2008 (22, [19-24]) and 2010 (23, [19-25]) was significantly lower than that in the normal group in 2008 (23, [20-25]) and in 2010 (24, [21-25]). CONCLUSIONS This study is the first, large-scale investigation of the influence of underweight on asthma control, and we have confirmed an adverse influence in a clinical setting. A potential mechanism for this interaction was unknown. Further investigation will be required.

Abstract
BACKGROUND Previous studies show that depression plays an important role in asthma. However, the association between asthma control and severity, and depression is inconclusive. METHODS To investigate the association between asthma control and severity, and depression, we assessed differences in asthma control and asthma severity between groups with various grades of depressive state as defined by the PHQ-9 score using data from the Japanese version of Patient Health Questionnaire-9 (J-PHQ-9) and a questionnaire survey including the Asthma Control Test (ACT). RESULTS The ACT scores in the symptom-screen positive (SP) and major/other depressive disorder (MDD/ODD) group were significantly lower than those in the symptom-screen negative (SN) and non-MDD/ODD groups, respectively. The rate of step1 and of step 3 and 4 in the SP group were significantly lower and higher than those in the SN group, respectively. When the SP group was divided into three, that is minimal, mild, and more than mild (MTM) depressive state subgroups, the ACT scores in the mild and MTM depressive state subgroups were significantly lower than those in the minimal depressive state subgroup. When the MTM subgroup was divided into moderate, moderate-severe and severe depressive state groups, however, there was no significant variation in ACT score and asthma severity among these three depressive state groups. CONCLUSIONS This study is the first, large-scale investigation of the use of the J-PHQ-9 in asthma patients. Using the J-PHQ-9 and the questionnaire, there was a clear association between asthma control and severity, and depression. As the depression became more severe, the existence of other depression-associated factors unrelated to asthma control and severity might be assumed, although further investigation will be required.

Abstract
BACKGROUND Despite the advances of asthma management and the accompanying improved asthma control, many problems related to asthma management still remain. The Niigata Asthma Treatment Study Group has been regularly collecting information via surveys since 1998 using a questionnaire, on problems related to asthma management; various studies on asthma management have been reported using data from the questionnaire. METHODS The aim of this study was to investigate the changes in asthma control and management for every two-year period using the data from 1998 to 2008; future problems requiring resolution were extracted and discussed. RESULTS The number of cases surveyed each year was about 3,000 (2,593-3,347 cases). The changes in the data from 1998 to 2008, including asthma attacks and symptoms rate, indicated the improvement of asthma control with the spread of medication according to the guidelines; of particular note, there was a 24.1% increase in the usage rate of inhaled corticosteroids during the study period. From 2002 to 2008, however, some asthmatic conditions seemed to show no improvement with regards to asthma control related to the rates of changes in peak flow meter use, leukotriene receptor antagonist use and oral sustained-released theophylline use. Moreover, there was no decrease in the occurrence of emergency episodes related to asthma deaths. CONCLUSION In the actual clinical setting, asthma control seems to be progressing well with the appropriate changes of medication according to the guidelines, and in part due to inhaled corticosteroid use. However, there were two problems which need to be addressed: 1) no improvement in some asthmatic conditions and 2) the occurrence of emergency episodes related to asthma deaths. In the future, it will be necessary to manage asthma in view of these points.

Abstract
BACKGROUND Despite the use of inhaled corticosteroid (ICS) becoming increasingly widespread, many problems related to asthma management still need to be addressed. One of them, obesity, has been reported to exert a harmful influence on asthma control. However, there have been few reports focusing not only on both obesity and its influence on Japanese asthma patients but also on the Japanese definition of obesity, as defined by the Japan Society for the Study of Obesity (JASSO). AIMS & METHODS The aim of this study was to confirm the influence of obesity, as defined by the JASSO, on asthma management in Japanese asthmatic patients. Using data from the Niigata Asthma Treatment Study Group 2008 questionnaire survey, differences between the "normal" group (18.5 kg/m(2) ≤ BMI <25 kg/m(2)) and the "obese" group (25 kg/m(2) ≤ BMI) were analyzed. RESULTS There was a significantly lower step 1 rate (19.4% v.s. 26.8%) and a higher proportion of patients using inhaled salmeterol (43.6% v.s. 35.8%) and leukotriene receptor antagonist (49.8% v.s. 40.8%) in the obese group relative to the normal group, although there were no significant differences in indicators of asthma control, including asthma control test scores. CONCLUSION This study investigated influences of JASSO-defined obesity on asthma severity and management in a clinical setting in Japan. It is possible that there are strong interactions between asthma and obesity, such as obesity causing decreased ICS therapy efficacy and leukotriene (LT)-related inflammation, although further investigation is necessary.

Abstract
BACKGROUND Inhaled corticosteroid (ICS) has played an important role in the management of asthma. Although several kinds of ICSs are currently available, there is no established strategy for ICS selection. METHODS Using the data from the 2004 questionnaire surveys by the Niigata Asthma Treatment Study Group, we analyzed relationships between each patient and the ICS employed on the basis of patient background, asthma control and treatment, and indicated characteristics of ICS selection by the physician. RESULTS Of 2852 cases, 2279 (79.9%) were ICS users, and 1513 (66.4% of ICS users) were classified as being in the fluticasone propionate (FP) group, 438 (19.2%) in the budesonide (BUD) group, and 240 (10.5%) in the hydrofluoroalkane-beclomethasone (HFA-BDP) group, indicating that FP was a standard ICS in this study. The mean age was significantly lower in the BUD group (52.3+/-18.2 years) and was significantly higher in the HFA-BDP group (59.9+/-17.0 years) than that in the FP group (55.8+/-16.6 years). The proportion of female patients was significantly higher not in the HFA-BDP (46.5%) but in the BUD group (59.0%) than in the FP group (51.1%). These results indicated that BUD was frequently prescribed to young female and HFA-BDP was employed in the elderly patients irrespective of gender compared with FP. CONCLUSIONS Our study indicates that ICS selection is reasonably adapted to each patient's background at least in the surveyed area. We need to elucidate the characteristics of ICS selection further in the future as new ICS and devices are developed.

Abstract
BACKGROUND Perimenstrual asthma (PMA) has been documented in 30% to 40% of asthmatic women; the characteristics of PMA have also been well described. However, there have been few epidemiological investigations of PMA in practice. In this study, we analyzed PMA based on a questionnaire survey carried out in Japan and compared the results with those of studies reported previously. METHODS For 8 weeks from September through October 2004, a questionnaire survey was administered to patients with bronchial asthma and their attending physicians. The questionnaire surveyed asthma control, asthma-related emergencies and satisfaction in daily life. The attending physicians were questioned about patient profiles and medications. All female patients who were menstruating during the survey period and who were known to have asthma exacerbation related to menstruation were allocated to the PMA group; those who were not were allocated to the non-PMA group. RESULTS The rate of PMA in female patients who were menstruating during the survey period was 11.3% in this study. Characteristic features of the PMA group (n = 54) included more severe disease, worsened disease control and more aggressive patient management, including increased oral corticosteroid use compared with the non-PMA group. The rates of emergency episodes in the PMA group were higher than in the non-PMA group. There was a significant increase in aspirin intolerant asthma (AIA, 25.5%) in the PMA group compared with the non-PMA group (8.4%). CONCLUSIONS Attention should be paid to the lack of knowledge regarding PMA in patients with asthma in actual clinical settings. The low rate of PMA reported in this study may be due to the study method using self-reports of PMA by patients without sufficient knowledge, and may not be an accurate representation of the actual incidence of the disease. The clinical similarity of PMA to AIA in this study may also provide a new insight into the mechanism of PMA.

Abstract
OBJECTIVE Prevention of deaths due to asthma is one of the most important issues in asthma management. However, there are few epidemiological studies of asthma deaths in Japan. METHODOLOGY Over an 8-week period in Niigata Prefecture, Japan, a questionnaire on asthma control and emergency episodes was administered to adult asthmatic patients. A questionnaire was also given to the patients' physicians to obtain further clinical information. Patients who became unconscious during episodes of asthma, or who required intubation and ventilation, were allocated to a near-fatal asthma group (NFA). Patients who did not fulfill these criteria were allocated to the non-NFA group. The NFA group was divided into two subgroups, based on the date of their last NFA episode (old NFA>or= 5 years and recent NFA<4 years). RESULTS Characteristic features of the NFA group included severe disease (23.1%vs 7.6%) with more aggressive patient management, including inhaled corticosteroid use (84.3%vs 72.0%). Multiple regression analysis confirmed that aspirin-intolerant asthma (AIA) was strongly associated with NFA. There was no difference in the incidence of AIA between the recent and old NFA patients. This suggests the incidence of AIA in NFA did not improve over time. CONCLUSIONS A history of AIA may be a useful indicator of potential NFA and allow preventative methods to be introduced. It is therefore important to obtain a history of AIA and to be aware of the risk of NSAID administration to these patients.
