RESUMO
To demonstrate clinical value of clavulanic acid/amoxicillin (CVA/AMPC) 1:14 combination dry syrup for acute bacterial rhinosinusitis (ABRS), the efficacy and safety were evaluated in a multicenter, open-label, uncontrolled study in 27 children with ABRS. The proportion of subjects who were 'cured' at the test of cure as the primary endpoint was 88.5%. In subjects with a major pathogenic bacteria at baseline (i.e., Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis) bacterial eradication was achieved in ≥ 80% of the subjects with the exception of ß-lactamase non-producing ampicillin resistant H. influenzae: BLNAR and ß-lactamase producing ampicillin resistant H. influenzae: BLPAR (ß-lactamase producing amoxicillin/clavulanic acid resistant H. influenzae: BLPACR). The MIC of CVA/AMPC (1:14) was not higher than 4 µg/mL for all pathogens except one strain each of BLNAR and BLPAR (BLPACR). Drug-related adverse events were reported in 19% of patients (5/27 patients). All of the reported drug-related adverse events were classified as gastrointestinal disorders that have been commonly reported with antibacterial drugs. These results indicate that CVA/AMPC (1:14) was clinically useful for the treatment of ABRS and is also suggested that was effective especially for the treatment of ABRS in children caused by beta-lactamase-producing bacteria including M. catarrhalis.

BACKGROUND: Real-world data assessing characteristics of patients with asthma initiating inhaled corticosteroid/long-acting muscarinic antagonist/long-acting ß2-agonist (ICS/LAMA/LABA) triple therapy in Japan are limited. METHODS: Descriptive, observational study of patients with asthma aged ≥15 years newly initiating single- or multiple-inhaler triple therapy (SITT: fluticasone furoate/umeclidinium/vilanterol [FF/UMEC/VI], SITT: indacaterol/glycopyrronium bromide/mometasone furoate [IND/GLY/MF] or MITT) or ICS/LABA using JMDC/Medical Data Vision (MDV) health insurance databases from February 2021-February 2022 (first prescription date: index date). Patients were assigned to three non-mutually exclusive cohorts: A) new FF/UMEC/VI initiators; B) new FF/UMEC/VI, IND/GLY/MF, or MITT initiators; C) new FF/UMEC/VI, IND/GLY/MF, MITT or ICS/LABA initiators as initial maintenance therapy (IMT). Patient characteristics were assessed descriptively for 12-months pre-treatment initiation (baseline period). RESULTS: Cohort A: among new FF/UMEC/VI initiators, 12.8% and 0.1% (JMDC) and 21.7% and 0.9% (MDV) of patients had ≥1 moderate and severe exacerbation; 52.0% (JMDC) and 79.2% (MDV) had ICS/LABA use. Cohort B: most patients initiated FF/UMEC/VI and IND/GLY/MF over MITT (JMDC: 91.3% vs 8.7%; MDV: 67.8% vs 32.2%), with fewer exacerbations and lower rescue medication use. Cohort C: a greater proportion of FF/UMEC/VI initiators as IMT experienced a moderate exacerbation at index versus ICS/LABA initiators as IMT (JMDC: 17.8% vs 10.7%; MDV: 8.0% vs 5.1%). CONCLUSIONS: Patient characteristics were generally similar between treatment groups; SITT initiators had fewer exacerbations and lower rescue medication use than MITT initiators, represented by the greater proportion of IMT among SITT versus MITT initiators. Physicians may have prescribed triple over dual therapy as IMT in response to an exacerbation.

Purpose: There is currently limited evidence for the optimal timing of triple therapy initiation in Japan, which is crucial for optimizing strategies for the effective treatment of chronic obstructive pulmonary disease (COPD). This study assessed the impact of prompt vs delayed initiation of triple therapy following a COPD exacerbation on clinical and economic outcomes in patients in Japan. Patients and Methods: Retrospective cohort study of patients in the Medical Data Vision Co., Ltd. database initiating triple therapy as single-inhaler triple therapy (fluticasone furoate/umeclidinium/vilanterol or budesonide/glycopyrronium/formoterol) or multiple-inhaler triple therapy within 180 days of a moderate-to-severe exacerbation (index). For the main analysis, patients were categorized as prompt or delayed initiators, initiating triple therapy within 0-30 days or 31-180 days of index, respectively. Inverse probability of treatment weighting based on propensity scores was used to adjust for measured confounders between prompt and delayed cohorts. Results: For the main analysis, 610 (60.3%) and 402 (39.7%) patients were prompt and delayed initiators, respectively. The rate of subsequent moderate-to-severe exacerbations following index exacerbation was numerically lower in prompt vs delayed initiators (weighted rate ratio 0.95, 95% confidence interval [CI]: 0.74-1.21; P = 0.6603). Time-to-first subsequent moderate-to-severe exacerbation increased significantly in prompt vs delayed initiators (weighted hazard ratio 0.77, 95% CI: 0.64-0.93; P = 0.0053). In patients indexed on a severe exacerbation, delayed initiation resulted in significantly higher 90-day all-cause readmissions vs prompt initiation (42.1% vs 30.6%; P = 0.0329 [weighted estimates]). Weighted healthcare resource utilization rates were numerically lower in prompt vs delayed initiators, and weighted direct costs (all cause and COPD-related) were significantly lower in prompt initiators. Conclusion: This real-world study demonstrated that earlier initiation of triple therapy resulted in several benefits in clinical outcomes for COPD and may also reduce the economic burden of COPD management in Japan.

OBJECTIVE: The preventive effects of mood stabilizers on recurrence/relapse in bipolar disorders have been investigated mostly in bipolar I disorder (BPI) patients, with limited reports on bipolar II disorder (BPII) patients. Here, we conducted an explorative data analysis to investigate whether the preventive effect of lamotrigine on recurrence /relapse in BPII is better than in BPI. METHODS: Data from Japanese patients with a diagnosis of BPI or BPII according to DSM-IV-TR were analyzed in an open-label, noninterventional, naturalistic, prospective postmarketing surveillance study of lamotrigine. This study was carried out from October 2011 to November 2014, and each patient was observed for 1 year. The time to recurrence/relapse of mood episodes after commencement of lamotrigine treatment was evaluated as a primary endpoint. Kaplan-Meier curves were generated to compare the time to recurrence/relapse of mood episodes in BPI with in BPII using a log-rank test. RESULTS: Lamotrigine was associated with a significantly longer time to recurrence/relapse of mood episodes in BPII than in BPI (log-rank test, P = .0103). Lamotrigine also prolonged time to recurrence/relapse of mania-related episodes, including hypomanic episodes, more in BPII than in BPI (P = .0110). CONCLUSIONS: Although the preventive effect of lamotrigine on recurrence/relapse of mood episodes in BPI has been established in a variety of clinical studies, the present study suggests that lamotrigine may be more suitable for maintenance treatment in BPII than in BPI.
