THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2023; 11:3076-3083.e3. [PMID: 37169286 DOI: 10.1016/j.jaip.2023.04.036] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 04/10/2023] [Accepted: 04/17/2023] [Indexed: 05/13/2023]
Abstract
BACKGROUND Bronchial thermoplasty (BT) has been shown to be effective in randomized controlled trials of patients with severe asthma who failed to achieve disease control with high-dose inhaled corticosteroids combined with bronchodilators. However, the effectiveness of BT in real-world clinical settings, especially among the Asian population, has not been determined. OBJECTIVE To evaluate the effectiveness of BT using a nationwide database. METHODS Using the inpatient and outpatient data from the Japanese Diagnosis Procedure Combination database, we applied a self-controlled case series design to evaluate changes in the composite outcome of hospital admissions and emergency department visits, as well as systemic corticosteroid dose, between 1 year before and after BT. We also conducted subgroup analyses based on patients' profiles. RESULTS Among the 561 patients with asthma who underwent BT treatment between September 2014 and March 2020, 102 patients with at least 1 outcome were analyzed. Bronchial thermoplasty was significantly associated with an improvement in the composite outcome of hospital admission and emergency department visits (incidence rate ratio 0.53; 95% CI 0.44-0.64). Systemic corticosteroid use was reduced after BT sessions (1931.5 mg [1,341.2-3,725.3 mg] to 641.3 mg [134.2-1,691.1 mg] per person-year; P < .001). Although all groups showed a significant improvement in the composite outcome in the subgroup analyses, BT tended to be less effective among people older than 65 years and those with higher body mass index (>25 kg/m2). CONCLUSIONS The present study using real-world data suggests that BT may improve asthma control; however, the effectiveness of BT can vary depending on patient baseline profiles.

Abstract
BACKGROUND Validating the information recorded in administrative databases is essential. However, no study has comprehensively validated the accuracy of Japanese Diagnosis Procedure Combination (DPC) data on various respiratory diseases. Therefore, this study aimed to evaluate the validity of diagnoses of respiratory diseases in the DPC database. METHODS We conducted chart reviews of 400 patients hospitalized in the departments of respiratory medicine in two acute-care hospitals in Tokyo, between April 1, 2019 and March 31, 2021, and used them as reference standards. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of DPC data on 25 respiratory diseases were determined. RESULTS Sensitivity ranged from 22.2% (aspiration pneumonia) to 100% (chronic eosinophilic pneumonia and malignant pleural mesothelioma) and was <50% for eight diseases, while specificity was >90% for all diseases. PPV ranged from 40.0% (aspiration pneumonia) to 100% (coronavirus disease 2019, bronchiectasis, chronic eosinophilic pneumonia, pulmonary hypertension, squamous cell carcinoma, small cell carcinoma, lung cancer of other histological types, and malignant pleural mesothelioma) and was >80% for 16 diseases. Except for chronic obstructive pulmonary disease (82.9%) and interstitial pneumonia (other than idiopathic pulmonary fibrosis) (85.4%), NPV was >90% for all diseases. These validity indices were similar in both hospitals. CONCLUSIONS The validity of diagnoses of respiratory diseases in the DPC database was high in general, thereby providing an important basis for future studies.

Corticosteroid use with extracorporeal cardiopulmonary resuscitation for out-of-hospital cardiac arrest: A nationwide observational study. Resusc Plus 2022; 12:100308.

Abstract
Aim Several studies have reported that corticosteroid administration for cardiac arrest patients may improve outcomes. However, these previous studies have not examined the effect of corticosteroid use in out-of-hospital cardiac arrest (OHCA) patients administered extracorporeal cardiopulmonary resuscitation (ECPR). Therefore, we aimed to examine the effectiveness of corticosteroids in OHCA patients administered ECPR. Methods Using the Japanese Diagnosis Procedure Combination inpatient database, we included OHCA patients who were administered ECPR on the day of admission between July 2010 and March 2019. The patients were categorized into the corticosteroid and control groups according to whether they received corticosteroids on the day of admission or not. The primary outcome was in-hospital mortality and the secondary outcomes included percentages of neurologically favorable survival, major bleeding complications, and infection-related complications. We compared the outcomes using a propensity score matching analysis. Results We identified 6,142 eligible patients (459 vs 5,683, the corticosteroid and control group, respectively). One-to-four propensity score matching analysis (457 vs 1,827) showed in-hospital mortality was significantly higher in the corticosteroid group compared with the control group (82.1% vs 76.6%; risk difference, 5.5%; 95% CI, 1.5 to 9.5%). Neurologically favorable outcomes did not differ between the two groups (13.6% vs 16.9%; risk difference, −3.3%; 95% CI, −6.9 to 0.3%). The percentage of major bleeding complications and infection-related complications did not significantly differ between the two groups. Conclusions The results of this study demonstrated that administration of corticosteroids on the day of admission to OHCA patients administered ECPR was associated with increased in-hospital mortality.

Abstract
INTRODUCTION As of today, there is still a need to determine which COPD patients may benefit from ICS therapy, whether ICSs are useful in COPD patients without chronic bronchitis, and whether long-acting bronchodilators can reduce the risk of exacerbations in frequent exacerbators even if ICSs are not used, and whether combination therapy including ICSs is helpful in infrequent exacerbators to optimise the use of ICSs in COPD. Nevertheless, in recent years, a fair amount of evidence has been produced that, at least in part, can help define the role of ICSs in COPD better. AREAS COVERED Herein, the authors provide an overview of current use of ICS in COPD and discuss their value to the current treatment armamentarium. The article includes discussion of which patients will benefit best from the use of ICSs, their potential uses and adverse effects. EXPERT OPINION There is growing agreement on why, in whom, and when ICS therapy can be used in COPD, although the consensus is still lacking because of the heterogeneity of COPD. The use of blood eosinophil counts (BECs) is only helpful in T2 inflammation, while there is a lack of biomarkers indicating the presence of T1 and T17 immunity, which is poorly responsive to ICS. Identifying ICS-sensitive endotypes using specific biomarkers that have yet to be identified and validated is likely to demonstrate that ICSs can influence the natural course of COPD in at least a subset of patients.

Abstract
The anti-DIC biological agent, recombinant human soluble thrombomodulin (rhTM), is being used clinically for DIC treatment in Japan. Patients with acute cholangitis associated with DIC are severe and require improved treatment. In addition, although clinical efficacy of rhTM in patients with acute cholangitis and DIC is expected, its efficacy is controversial. Thus, it is useful to evaluate rhTM in patients with acute cholangitis with DIC. This study aimed to validate the hypothesis that rhTM use improves in-hospital mortality in patients with acute cholangitis with DIC. A propensity score-matching analysis using a nationwide administrative database, the Japanese Diagnosis Procedure Combination Inpatient Database from April 2012 to March 2018, was performed. This database includes administrative claims data for all inpatients discharged from more than 1,000 participating hospitals, covering 92% of all tertiary-care emergency hospitals in Japan. Eligible patients (n = 2,865) were categorized into the rhTM (n = 1,636) or control groups (n = 1,229). Propensity score-matching created a matched cohort of 910 pairs with and without rhTM. In-hospital mortality between the groups in the unmatched analysis showed no significant difference (rhTM vs. control; 10.8% vs. 12.2%; p = 0.227). However, in-hospital mortality between the groups in the propensity score-matched analysis showed a significant difference (rhTM vs. control; 9.5% vs. 12.9%; p = 0.021). These results demonstrated that the rhTM group had significantly lower in-hospital mortality for patients with acute cholangitis with DIC. We propose that rhTM should be used for the treatment of patients with acute cholangitis with DIC.

Abstract
BACKGROUND Inhaled corticosteroids (ICS) are indicated for prevention of exacerbations in patients with COPD, but they are frequently overprescribed. ICS withdrawal has been recommended by international guidelines in order to prevent side effects in patients in whom ICS are not indicated. METHOD Observational comparative effectiveness study aimed to evaluate the effect of ICS withdrawal versus continuation of triple therapy (TT) in COPD patients in primary care. Data were obtained from the Optimum Patient Care Research Database (OPCRD) in the UK. RESULTS A total of 1046 patients who withdrew ICS were matched 1:4 by time on TT to 4184 patients who continued with TT. Up to 76.1% of the total population had 0 or 1 exacerbation the previous year. After controlling for confounders, patients who discontinued ICS did not have an increased risk of moderate or severe exacerbations (adjusted HR: 1.04, 95% confidence interval (CI) 0.94-1.15; p = 0.441). However, rates of exacerbations managed in primary care (incidence rate ratio (IRR) 1.33, 95% CI 1.10-1.60; p = 0.003) or in hospital (IRR 1.72, 95% CI 1.03-2.86; p = 0.036) were higher in the cessation group. Unsuccessful ICS withdrawal was significantly and independently associated with more frequent courses of oral corticosteroids the previous year and with a blood eosinophil count ≥ 300 cells/μL. CONCLUSIONS In this primary care population of patients with COPD, composed mostly of infrequent exacerbators, discontinuation of ICS from TT was not associated with an increased risk of exacerbation; however, the subgroup of patients with more frequent courses of oral corticosteroids and high blood eosinophil counts should not be withdrawn from ICS.
