RESUMO
BACKGROUND: Japanese guidelines recommend triple inhaled corticosteroid (ICS)/long-acting muscarinic antagonist (LAMA)/long-acting ß2-agonist (LABA) therapy in patients with chronic obstructive pulmonary disease (COPD) and no concurrent asthma diagnosis who experience frequent exacerbations and have blood eosinophil (EOS) count ≥ 300 cells/mm3, and in patients with COPD and asthma with continuing/worsening symptoms despite receiving dual ICS/LABA therapy. These post-hoc analyses of the KRONOS study in patients with COPD and without an asthma diagnosis, examine the effects of fixed-dose triple therapy with budesonide/glycopyrronium/formoterol fumarate dihydrate (BGF) versus dual therapies on lung function and exacerbations based on blood EOS count - focusing on blood EOS count 100 to < 300 cells/mm3 - as a function of exacerbation history and COPD severity. METHODS: In KRONOS, patients were randomized to receive treatments that included BGF 320/14.4/10 µg, glycopyrronium/formoterol fumarate dihydrate (GFF) 14.4/10 µg, or budesonide/formoterol fumarate dihydrate (BFF) 320/10 µg via metered dose inhaler (two inhalations twice-daily for 24 weeks). These post-hoc analyses assessed changes from baseline in morning pre-dose trough forced expiratory volume in 1 s (FEV1) over 12-24 weeks and moderate or severe COPD exacerbations rates over 24 weeks. The KRONOS study was not prospectively powered for these subgroup analyses. RESULTS: Among patients with blood EOS count 100 to < 300 cells/mm3, least squares mean treatment differences for lung function improvement favored BGF over BFF in patients without an exacerbation history in the past year and in patients with moderate and severe COPD, with observed differences ranging from 62 ml to 73 ml across populations. In this same blood EOS population, moderate or severe exacerbation rates were reduced for BGF relative to GFF by 56% in patients without an exacerbation history in the past year, by 47% in patients with moderate COPD, and by 50% in patients with severe COPD. CONCLUSIONS: These post-hoc analyses of patients with moderate-to-very severe COPD from the KRONOS study seem to indicate clinicians may want to consider a step-up to triple therapy in patients with persistent/worsening symptoms with blood EOS count > 100 cells/mm3, even if disease severity is moderate and there is no recent history of exacerbations.

INTRODUCTION: Use of propellants with high global warming potential (such as HFA-134a) for pressurised metered-dose inhalers (pMDIs) is being phased down. Switching to dry-powder inhalers may not be clinically feasible for all patients; an alternative is reformulation using propellants with low global warming potential. The combination of beclometasone dipropionate/formoterol fumarate/glycopyrronium bromide (BDP/FF/GB) is available for asthma or chronic obstructive pulmonary disease via pMDI using HFA-134a as propellant. This is being reformulated using the low global warming potential propellant HFA-152a. This manuscript reports three studies comparing BDP/FF/GB pharmacokinetics delivered via pMDI using HFA-152a vs HFA-134a. METHODS: The studies were four-way crossover, single-dose, randomised, double-blind, in healthy volunteers. In Studies 1 and 2, subjects inhaled four puffs of BDP/FF/GB (Study 1: 100/6/12.5 µg [medium-strength BDP]; Study 2: 200/6/12.5 µg [high-strength]), ingesting activated charcoal in two of the periods (once per propellant). In Study 3, subjects inhaled medium- and high-strength BDP/FF/GB using a spacer. All three studies compared HFA-152a vs HFA-134a in terms of lung availability and total systemic exposure of beclometasone-17-monopropionate (B17MP; active metabolite of BDP), BDP, formoterol and GB. Bioequivalence was concluded if the 90 % confidence intervals (CIs) of the ratios between formulations of the geometric mean maximum plasma concentration (Cmax) and area under the plasma concentration-time curve between time zero and the last quantifiable timepoint (AUC0-t) for the analytes were between 80 and 125 %. RESULTS: In Studies 1 and 2, systemic exposure bioequivalence (i.e., comparisons without charcoal block) was demonstrated, except for GB Cmax in Study 2 (upper 90 % CI 125.11 %). For lung availability (i.e., comparisons with charcoal block), B17MP and formoterol demonstrated bioequivalence in both studies, as did BDP in Study 2; in Study 1, BDP upper CIs were 126.96 % for Cmax and 127.34 % for AUC0-t). In Study 1, GB AUC0-t lower CI was 74.54 %; in Study 2 upper limits were 135.64 % for Cmax and 129.12 % for AUC0-t. In Study 3, the bioequivalence criteria were met for BDP, B17MP and formoterol with both BDP/FF/GB strengths, and were met for GB AUC0-t, although not for Cmax. Both formulations were similarly well tolerated in all three studies. CONCLUSIONS: Overall, while formal bioequivalence cannot be concluded for all analytes, these data suggest therapeutic equivalence of the new formulation with the existing BDP/FF/GB pMDI formulation, therefore supporting reformulation using a propellant with low global warming potential.

BACKGROUND: Helicobacter pylori (H. pylori) is strongly associated with peptic ulcer disease and gastric cancer. We evaluated two triple therapy regimens comprising esomeprazole, high dose bismuth, and different doses of amoxicillin for first-line H. pylori eradication. MATERIALS AND METHODS: Two hundred patients with dyspepsia and naive H. pylori infection were randomly assigned into two groups (n = 100). Both groups were treated for 14 days similarly with esomeprazole (40 mg, twice daily) and bismuth subcitrate (240 mg, three times daily), but the dose of amoxicillin was varied between Groups A (750 mg) and B (1000 mg) three times daily. Treatment compliance and side effect were evaluated following the therapies and after 8 weeks, a negative test of stool H. pylori antigen confirmed eradication. RESULTS: The two groups were comparable with respect to sex and age. According to intention to treat analysis, eradication rates were 80% (95% CI: 77.2%-82.8%) and 90% (95% CI: 84.1%-95.9%) in A and B groups, respectively (p = 0.22). Per-protocol eradication rates were 87% (95% CI: 80.4%-93.6%) and 92.8% (95% CI: 87.7%-97.9%), respectively (p = 0.23). Severe adverse effects were 3% and 2%, respectively (p = 0.34). CONCLUSION: High dose esomeprazole, amoxicillin and bismuth achieved 92.8% cure rates per protocol in a country with a high background rate of resistance. Additional studies are needed to ascertain whether this therapy can be further improved. Until then, it can be recommended as a first-line H. pylori eradication in north of Iran.

PURPOSE OF THE REVIEW: Antiphospholipid syndrome (APS) is a rare systemic autoimmune disorder that can escalate into a 'thrombotic storm' called the catastrophic antiphospholipid syndrome (CAPS), frequently requiring ICU admission for multiple organ failure. This review aims to offer insight and recent evidence on critically-ill APS patients. RECENT FINDINGS: The CAPS classification criteria define this condition as the involvement of at least three organs/systems/tissues within less than a week, caused by small vessel thrombosis, in patients with elevated antiphospholipid antibodies levels. These criteria do not encompass the full spectrum of critically-ill thrombotic APS patients and they need to be cautiously used for the bedside diagnosis of CAPS. Thrombocytopenia is the laboratory hallmark of CAPS, sometimes dropping below 20G/L, but a complete thrombotic microangiopathy pattern is infrequent. Anticoagulation is the pivotal treatment for APS and CAPS, associated with improved outcome. Triple therapy - the combination of anticoagulation, high-dose corticosteroids, and either plasma exchange or intravenous immunoglobulins - remains the standard treatment for CAPS patients. Eculizumab, an anti-C5 monoclonal antibody, may be useful in refractory patients. Despite significant progress, CAPS mortality rate remains high. Its diagnosis and management are complex, requiring a close multidisciplinary cross talk between APS specialists and intensivists.

OBJECTIVE: In Japan, the optimal initiation timing and efficacy of single-inhaler triple therapy (SITT) in asthma management remain unexplored. This study investigated SITT initiation timing following an asthma exacerbation, and examined patient demographics and clinical characteristics. METHODS: Observational, retrospective cohort study in patients with asthma aged ≥15 years who initiated SITT following their earliest observed asthma exacerbation (February-November 2021), using data from Japanese health insurance claims databases (JMDC and Medical Data Vision [MDV]). The study period ended May 2022 for JMDC and September 2022 for MDV. Descriptive analyses were performed independently by database. Variables evaluated included timing of SITT initiation post exacerbation (prompt, delayed and late, ≤30, 31-180 and >180 days post index, respectively), patient demographics, clinical characteristics, and pre-index treatment. RESULTS: Of patients in the JMDC and MDV databases, most initiated SITT promptly after an asthma exacerbation, 60.8% (n = 951/1565) and 44.4% (n = 241/543), respectively. Delayed initiation occurred in 22.6% (n = 354/1565) and 26.3% (n = 143/543) of patients, and late initiation occurred in 16.6% (n = 260/1565) and 29.3% (n = 159/543), respectively. Most patients were indexed on a moderate asthma-related exacerbation, 97.1% (n = 1519/1565) and 68.7% (n = 373/543), respectively. CONCLUSION: Most patients with asthma initiated SITT promptly following a moderate exacerbation, with delayed and late initiation more common among patients with complex clinical profiles. The findings underscore the necessity for future research to examine the interaction between patient characteristics, clinical outcomes, and the timing of SITT initiation to optimize treatment strategies, as clinical practice may vary by exacerbation severity.
RESUMO
PURPOSE: This study aimed to examine reports of cardiovascular adverse events (CV AEs) observed in the real-world during treatment with aclidinium, tiotropium, glycopyrronium, and umeclidinium alone or in combination with a LABA and, in the context of triple therapy, with the addition of an ICS, and submitted to the food and drug administration adverse event reporting system (FAERS). METHODS: A retrospective disproportionality analysis was conducted utilizing CV AE reports submitted to the FAERS from January 2020 to 30 September 2023. Disproportionality was measured by calculating the reporting odds ratio. RESULTS: Compared with ipratropium, tiotropium was associated with fewer reports of CV AEs. Compared with tiotropium, other LAMAs were more likely to be associated with reports of CV AEs. Combinations of glycopyrronium with indacaterol or formoterol and umeclidinium with vilanterol significantly reduced reports of CV AEs compared with the respective LAMA. The addition of an ICS to these combinations further reduced the risk of CV AE reports. CONCLUSION: Our study suggests that inhaled LAMAs are not free from cardiac AE risks. This risk may be more evident when the newer LAMAs are used, but it is generally significantly reduced when COPD patients are treated with dual bronchodilators or triple therapy. However, these results do not prove that LAMAs cause CV AEs, as FAERS data alone are not indicative of a drug's safety profile. Given the frequency with which COPD and cardiovascular disease co-exist, a large study in the general population could shed light on this very important issue.

BACKGROUND: Randomized controlled trials described beneficial effects of inhaled triple therapy (LABA/LAMA/ICS) in patients with chronic obstructive pulmonary disease (COPD) and high risk of exacerbations. We studied whether such effects were also detectable under continuous treatment in a retrospective observational setting. METHODS: Data from baseline and 18-month follow-up of the COPD cohort COSYCONET were used, including patients categorized as GOLD groups C/D at both visits (n = 258). Therapy groups were defined as triple therapy at both visits (triple always, TA) versus its complement (triple not always, TNA). Comparisons were performed via multiple regression analysis, propensity score matching and inverse probability weighting to adjust for differences between groups. For this purpose, variables were divided into predictors of therapy and outcomes. RESULTS: In total, 258 patients were eligible (TA: n = 162, TNA: n = 96). Without adjustments, TA patients showed significant (p < 0.05) impairments regarding lung function, quality of life and symptom burden. After adjustments, most differences in outcomes were no more significant. Total direct health care costs were reduced but still elevated, with inpatient costs much reduced, while costs of total and respiratory medication only slightly changed. CONCLUSION: Without statistical adjustment, patients with triple therapy showed multiple impairments as well as elevated treatment costs. After adjusting for differences between treatment groups, differences were reduced. These findings are compatible with beneficial effects of triple therapy under continuous, long-term treatment, but also demonstrate the limitations encountered in the comparison of controlled intervention studies with observational studies in patients with severe COPD using different types of devices and compounds.

BACKGROUND: Medication non-adherence is a significant problem in patients with Chronic Obstructive Pulmonary Disease (COPD). Efforts to address this issue are receiving increased attention. Simplifying treatment by prescribing single-inhaler triple therapy (SITT) as an alternative to multi-inhaler triple therapy (MITT) or with smart inhalers are often considered potential solutions. However, the actual impact of these innovations on adherence and clinical outcomes is unclear. METHODS: To address this knowledge gap we first conducted a literature review focusing on two research questions: 1) the difference in adherence between SITT and MITT users in COPD, and 2) the effect of smart inhalers on adherence in COPD. Separate searches were conducted in PubMed and two authors independently assessed the articles. In addition, we present a protocol for a study to acquire knowledge for the gaps identified. RESULTS: To address the first research question, 8 trials were selected for further review. All trials were observational, i.e. randomized controlled trials were lacking. Seven of these trials showed higher adherence and/or persistence in patients on SITT compared with patients on MITT. In addition, four studies showed a positive effect of SITT on various clinical outcomes. For the second research question, 11 trials were selected for review. While most of the studies showed a positive effect of smart inhalers on adherence, there was considerable variation in the results regarding their effect on other clinical outcomes. The TRICOLON (TRIple therapy COnvenience by the use of one or multipLe Inhalers and digital support in ChrONic Obstructive Pulmonary Disease) trial aims to improve understanding regarding the effectiveness of SITT and smart inhalers in enhancing adherence. This open-label, randomized, multi-center study will enroll COPD patients requiring triple therapy at ten participating hospitals. In total, 300 patients will be randomized into three groups: 1) MITT; 2) SITT; 3) SITT with digital support through a smart inhaler and an e-health platform. The follow-up period will be one year, during which three methods of measuring adherence will be used: smart inhaler data, self-reported data using the Test of Adherence to Inhalers (TAI) questionnaire, and drug analysis in scalp hair samples. Finally, differences in clinical outcomes between the study groups will be compared. DISCUSSION: Our review suggests promising results concerning the effect of SITT, as opposed to MITT, and smart inhalers on adherence. However, the quality of evidence is limited due to the absence of randomized controlled trials and/or the short duration of follow-up in many studies. Moreover, its impact on clinical outcomes shows considerable variation. The TRICOLON trial aims to provide solid data on these frequently mentioned solutions to non-adherence in COPD. Collecting data in a well-designed randomized controlled trial is challenging, but the design of this trial addresses both the usefulness of SITT and smart inhalers while ensuring minimal interference in participants' daily lives.

BACKGROUND: Quadruple therapy is recommended for the management of patients with heart failure (HF) and reduced ejection fraction (HFrEF). In order to provide background and identify barriers to quadruple therapy, in this study, the aim was to explore the time to initiation of triple therapy in a population-based cohort of patients with de novo HF. METHODS: Adult patients with de novo hospital or emergency department (ED) diagnosis of HF between April 1, 2008, and March 31, 2018, in Alberta, Canada, were included and were linked to echocardiography data to identify patients with HFrEF (EF ≤ 40%). Any treatment with angiotensin-converting enzyme inhibitors/ angiotensin receptor blockers/ angiotensin receptor neprilysin inhibitors, beta-blockers, and mineralocorticoid receptor antagonists was captured if prescribed for ≥ 28 days and filled at least once during the 12 months after the index episode. RESULTS: Among 14,092 patients with de novo HF and available echocardiography data, 54.9% had HFrEF. By 1 year after diagnosis, of those in the HFrEF cohort, 9.5% had received no therapy, 27.5% monotherapy, 41.6% dual therapy, and 21.4% triple therapy. The median (interquartile range) of time to mono-, dual- and triple therapy in patients with HFrEF were 1 (0, 26), 8 (0, 44), and 14 (0, 52) days, respectively. Patients who received triple therapy were younger, more likely to be male and to have higher frequencies of coronary artery disease, higher glomerular filtration rates and lower left ventricular ejection fraction levels compared to their counterparts. Patients with triple therapy had lower rates of clinical outcomes compared to those on no, mono or dual therapy (adjusted hazard ratio 0.15, 95% confidence interval 0.13, 0.17 for the composite outcome of death, hospitalization due to HF, or ED visit due to HF). CONCLUSION: Despite guideline recommendations, triple therapy is underused and is slowly deployed in patients with HFrEF, even after hospitalization and ED presentation.

BACKGROUND: Small airways disease plays a key role in the pathogenesis of chronic obstructive pulmonary disease (COPD) and is a major cause of obstruction; therefore, it is a critical pharmacotherapy target. This study evaluated lung deposition of two inhaled corticosteroid (ICS)/long-acting ß2-agonist/long-acting muscarinic antagonist single-inhaler triple therapies using in silico functional respiratory imaging (FRI). Deposition was assessed using real-world inhalation profiles simulating everyday use where optimal inhalation may be compromised. METHODS: Three-dimensional airway models were produced from 20 patients with moderate-to-very severe COPD. Total, central, and regional small airways deposition as a percentage of delivered dose of budesonide/glycopyrronium/formoterol fumarate dihydrate (BGF) 160/7.2/5 µg per actuation and fluticasone furoate/umeclidinium/vilanterol (FF/UM/VI) 100/62.5/25 µg were evaluated using in silico FRI based on in vitro aerodynamic particle size distributions of each device. Simulations were performed using multiple inhalation profiles of varying durations and flow rates representing patterns suited for a pressurized metered-dose inhaler or dry-powder inhaler (four for BGF, two for FF/UM/VI, with one common profile). For the common profile, deposition for BGF versus FF/UM/VI was compared post-hoc using paired t-tests. RESULTS: Across inhalation profiles, mean total lung deposition was consistently higher with BGF (47.0-54.1%) versus FF/UM/VI (20.8-22.7%) and for each treatment component, with greater deposition for BGF also seen in the central large airways. Mean regional small airways deposition was also greater across inhalation profiles with BGF (16.9-23.6%) versus FF/UM/VI (6.8-8.7%) and for each treatment component. For the common profile, total, central, and regional small airways deposition were significantly greater for BGF versus FF/UM/VI (nominal p < 0.001), overall and for treatment components; notably, regional small airways deposition of the ICS components was approximately five-fold greater with budesonide versus fluticasone furoate (16.1% vs. 3.3%). CONCLUSIONS: BGF was associated with greater total, central, and small airways deposition for all components versus FF/UM/VI. Importantly, using an identical inhalation profile, there was an approximately five-fold difference in small airways deposition for the ICS components, with only a small percentage of the ICS from FF/UM/VI reaching the small airways. Further research is needed to understand if the enhanced delivery of BGF translates to clinical benefits.

BACKGROUND: Vonoprazan-containing Helicobacter pylori eradication is reliably effective in Japan. Its effectiveness in other countries remains unclear. Here, we examined vonoprazan-H. pylori therapies in Thailand. MATERIALS AND METHODS: This was pilot study of four different vonoprazan containing therapies. Subjects were randomized to: 14-day dual therapy (500 mg amoxicillin q.i.d. plus 20 mg vonoprazan b.i.d.), 14-day triple therapy (amoxicillin 1 g b.i.d., slow release clarithromycin-MR, 1 g daily plus vonoprazan 20 mg b.i.d.), 7-day high-dose vonoprazan triple therapy (amoxicillin 1 g b.i.d., clarithromycin-MR 1 g daily and 60 mg vonoprazan once daily), and 14-day vonoprazan triple therapy plus bismuth (amoxicillin 1 g b.i.d., clarithromycin-MR 1 g daily, vonoprazan 20 mg b.i.d., and bismuth subsalicylate 1048 mg b.i.d.). Eradication was confirmed 4 weeks after therapy. Antimicrobial susceptibility and CYP3A4/5 genotyping were performed. RESULTS: One hundred H. pylori-infected patients (mean age 54.3 ± 13 years, 51% men) were randomized. All were CYP3A4 extensive metabolizers. Cure rates with both 14-day vonoprazan dual therapy and 14-day triple therapy were low: 66.7%; 95% CI = 43-85% (14/21), and 59.3%; 95% CI = 39-78%) (16/27), respectively. In contrast, 7-day high-dose vonoprazan triple therapy and 14-day vonoprazan triple plus bismuth proved effective 92.3%; 95% CI = 75%-99% (24/26) and 96.2%; 95% CI = 80%-100% (25/26), respectively. CONCLUSION: Both 14-day vonoprazan dual and triple therapy were ineffective for H. pylori eradication in Thailand. Higher dosage of vonoprazan, and/or the addition of bismuth may be required to achieve high H. pylori eradication rates. High-dose vonoprazan triple therapy and vonoprazan triple therapy adding bismuth might be used as first-line treatments in some regions with high efficacy irrespective of CYP3A4/5 genotype and clarithromycin resistance.

OBJECTIVE: To review the evidence for the use of open-inhaler (inhaled corticosteroid [ICS] plus long-acting ß2-agonist [LABA] with separate add-on long-acting muscarinic antagonist [LAMA]) versus single-inhaler triple therapy (ICS/LABA/LAMA combination) and the merits of add-on LAMA to ICS/LABA in patients with uncontrolled asthma. DATA SOURCES: Original research articles were identified from PubMed using the search term "triple therapy asthma." Information was also retrieved from the ClinicalTrials.gov website. STUDY SELECTIONS: Articles detailing the use of add-on LAMA to ICS plus LABA (open-inhaler triple therapy), and closed triple therapy compared with ICS plus LABA dual therapy, addressing patient symptoms, exacerbations, and health-related quality of life. RESULTS: Open-inhaler triple therapy was associated with a significantly reduced incidence of hospitalizations and emergency department visits and a decrease in ICS dose, oral corticosteroids use, and antibiotics use. Exacerbations and acute respiratory events were also reduced. Single-inhaler triple therapy showed a greater improvement in lung function, asthma control, and health status and was noninferior to open-inhaler triple therapy for Asthma Quality of Life Questionnaire scores. Single-inhaler triple therapy may also lead to improved therapy adherence. CONCLUSION: Add-on LAMA to ICS plus LABA (open- or single-inhaler triple therapy) improves the response in patients who remain symptomatic and provides a reasonable alternative to ICS dose escalation in treatment-refractory patients.

INTRODUCTION: Helicobacter pylori infects a large percentage of the world's population and is etiologically related to gastric cancer. The U.S. Food and Drug Administration recently approved two 14-day vonoprazan-containing regimens (vonoprazan-amoxicillin with or without clarithromycin) for H. pylori infections in the United States/Europe. METHODS: We critically reviewed the trial methods to discover why the results were unacceptable low [i.e., no regimen achieved clinically acceptable (≥ 90%) or even conditionally acceptable cure rates (≥ 85%)]. Cure rates with antibiotic susceptible strains were 84.7 for vonoprazan triple therapy, 78.5 for vonoprazan-amoxicillin, and 78.7 for lansoprazole triple therapy, respectively. As was previously shown in Japan, the benefit from adding clarithromycin to vonoprazan-amoxicillin was minimal and the majority of the clarithromycin administered was unnecessary. RESULTS: The possible reasons for failure to achieve high cure rates discussed include (a) reduced intragastric antibiotic concentrations, (b) an increase in heteroresistance, and (c) failure to achieve an intragastric pH conducive for amoxicillin to eradicate the infection. In addition, there was no pilot study or other attempt to optimize any regimen. CONCLUSION: The most likely reason for failure was failure to achieve high intragastric concentrations of antibiotics or to achieve an intragastric pH conducive for amoxicillin to be active. Importantly, vonoprazan triple therapy resulted in > 10 tons of unneeded clarithromycin/million courses of vonoprazan triple therapy. Antibiotic misuse combined with low cure rates suggest that vonoprazan-clarithromycin triple therapies should not be prescribed for H. pylori infection. Dual vonoprazan-amoxicillin therapy has proven effective elsewhere and after optimization may eventually prove useful in the U.S./Europe.

BACKGROUND: The fracture risk of patients with chronic obstructive pulmonary disease (COPD) treated with inhaled corticosteroids is controversial. And some large-scale randomized controlled trials have not solved this problem. The purpose of our systematic review and meta-analysis including 44 RCTs is to reveal the effect of inhaled corticosteroids on the fracture risk of COPD patients. METHODS: Two reviewers independently retrieved randomized controlled trials of inhaled corticosteroids or combinations of inhaled corticosteroids in the treatment of COPD from PubMed, Embase, Medline, Cochrane Library, and Web of Science. The primary outcome was a fracture event. This study was registered at PROSPERO (CRD42022366778). RESULTS: Forty-four RCTs were performed in 87,594 patients. Inhaled therapy containing ICSs (RR, 1.19; 95%CI, 1.04-1.37; P = 0.010), especially ICS/LABA (RR, 1.30; 95%CI, 1.10-1.53; P = 0.002) and triple therapy (RR, 1.49; 95%CI, 1.03-2.17; P = 0.04) were significantly associated with the increased risk of fracture in COPD patients when compared with inhaled therapy without ICSs. Subgroup analyses showed that treatment duration ≥ 12 months (RR, 1.19; 95%CI, 1.04-1.38; P = 0.01), budesonide therapy (RR, 1.64; 95%CI., 1.07-2.51; P = 0.02), fluticasone furoate therapy (RR, 1.37; 95%CI, 1.05-1.78; P = 0.02), mean age of study participants ≥ 65 (RR, 1.27; 95%CI, 1.01-1.61; P = 0.04), and GOLD stage III(RR, 1.18; 95%CI, 1.00-1.38; P = 0.04) were significantly associated with an increased risk of fracture. In addition, budesonide ≥ 320 ug bid via MDI (RR, 1.75; 95%CI, 1.07-2.87; P = 0.03) was significantly associated with the increased risk of fracture. CONCLUSION: Inhalation therapy with ICSs, especially ICS/LABA or triple therapy, increased the risk of fracture in patients with COPD compared with inhaled therapy without ICS. Treatment duration, mean age of participants, GOLD stage, drug dosage form, and drug dose participated in this association. Moreover, different inhalation devices of the same drug also had differences in risk of fracture.

BACKGROUND: Despite the evidence-based guidelines promoted by the Global Initiative for Chronic Obstructive Lung Disease (GOLD), the overuse of prescription drugs to manage COPD, particularly inhaled corticosteroids (ICS), remains a persistent challenge. In this real-world study, we evaluated how patients with COPD were divided into ABCD groups based on the 2017 GOLD guidelines, determined the rate of adherence to the GOLD treatment recommendations, described the rate of ICS usage, and determined the rate of triple therapy (TT) prescription. METHODS: The charts of 2291 patients diagnosed with COPD were retrospectively analyzed, of which 1438 matched the eligibility criteria. RESULTS: The average patient age was 69.6 ± 10.9 years; 52% of patients were female. The average COPD assessment test (CAT) score was 18.3 ± 9.1. The ABCD breakdown was as follows: group A 19.5%, group B 64.1%, group C 1.8%, and group D 14.6%. All groups, except group D, showed discordance in COPD treatment relative to the proposed GOLD guidelines. Only 18.9% of group A and 26% of group B were treated in concordance with the guidelines. TT was primarily used in group D (63.3%) and overused in groups A (30.6%) and B (47.8%). ICS was overused in all groups, particularly in groups A (56.2%) and B (67.3%). CONCLUSION: Studies from the last decade have consistently revealed a lack of conformity between what physicians prescribe and what GOLD guidelines recommend. The excessive usage of ICS, which continues despite all the associated adverse effects and the attributable costs, is concerning. The awareness of GOLD guidelines among primary care physicians (PCPs) and respiratory specialists needs to be improved.

In evidence-based medicine, N-of-1 trials are increasingly attractive for rare and heterogeneous conditions. A recent French study illustrates this convincingly in the field of cystic fibrosis. A highly effective triple therapy (ETI) is currently available in Europe, which will eventually help the 85 % of Belgian patients carrying at least one copy of the F508del mutation. Most other 2.000 or so putative mutations of this gene are poorly characterised and very rare or private. To predict the efficacy of ETI at the individual level in currently ineligible patients, sophisticated tools are advocated, but they are expensive, not widely available, often partially standardised and there still remains a «grey area¼ concerning their reliability in this context. With-out using them, the French study suggests that more than half of these patients show clinically meaningful responses to a 4-6 weeks trial of ETI. What makes this pragmatic, cost-effective, non-invasive and simplified approach possible (type 2 N-of-1 trials) is the dramatic and rapid efficacy of a life-saving treatment without alternative and the fact that it can be assessed using simple and robust clinical and paraclinical outcomes. Here, we describe one such trial and discuss the value and limitations of this approach.
Dans la médecine basée sur les preuves, les essais de taille 1 suscitent un intérêt croissant dans les affections rares et hétérogènes. Une récente étude française l'illustre de manière convaincante dans la mucoviscidose. Une trithérapie extrêmement efficace (ETI) est actuellement disponible en Europe, concernant à terme en Belgique les 85 % de patients porteurs d'au moins une copie de la mutation F508del. La majorité des quelque 2.000 autres mutations putatives de ce gène sont mal caractérisées et rarissimes. Des techniques sophistiquées sont évoquées pour prédire, à l'échelle individuelle, l'efficacité d'ETI chez les patients actuellement non éligibles, mais elles sont peu disponibles, coûteuses, souvent imparfaitement standardisées et leur interprétabilité conserve une «zone grise¼. Sans y recourir, l'étude française montre que plus de la moitié de ces patients répondent d'une manière évidente à un essai d'ETI pendant quelques semaines seulement. Ce qui permet cette approche pragmatique, économique, non invasive et simplifiée (essai de taille 1, de type 2), c'est l'efficacité spectaculaire et rapide d'un traitement salvateur sans alternative et le fait qu'elle puisse être appréhendée à partir de critères cliniques et paracliniques simples et robustes. Nous rapportons ici un essai de ce type et discutons l'intérêt et les limites de cette approche.

Fibroblast growth factor 21 (FGF21) is increased acutely by carbohydrate ingestion and is elevated in patients with type 2 diabetes (T2D). However, the physiological significance of increased FGF21 in humans remains largely unknown. We examined whether FGF21 contributed to the metabolic improvements observed following treatment of patients with T2D with either triple (metformin/pioglitazone/exenatide) or conventional (metformin/insulin/glipizide) therapy for 3 yr. Forty-six patients with T2D were randomized to receive either triple or conventional therapy to maintain HbA1c < 6.5%. A 2-h 75-g oral glucose tolerance test (OGTT) was performed at baseline and following 3 years of treatment to assess glucose tolerance, insulin sensitivity, and ß-cell function. Plasma total and bioactive FGF21 levels were quantitated before and during the OGTT at both visits. Patients in both treatment arms experienced significant improvements in glucose control, but insulin sensitivity and ß-cell function were markedly increased after triple therapy. At baseline, FGF21 levels were regulated acutely during the OGTT in both groups. After treatment, fasting total and bioactive FGF21 levels were significantly reduced in patients receiving triple therapy, but there was a relative increase in the proportion of bioactive FGF21 compared with that observed in conventionally treated subjects. Relative to baseline studies, triple therapy treatment also significantly modified FGF21 levels in response to a glucose load. These changes in circulating FGF21 were correlated with markers of improved glucose control and insulin sensitivity. Alterations in the plasma FGF21 profile may contribute to the beneficial metabolic effects of pioglitazone and exenatide in human patients with T2D.NEW & NOTEWORTHY In patients with T2D treated with a combination of metformin/pioglitazone/exenatide (triple therapy), we observed reduced total and bioactive plasma FGF21 levels and a relative increase in the proportion of circulating bioactive FGF21 compared with that in patients treated with metformin and sequential addition of glipizide and basal insulin glargine (conventional therapy). These data suggest that FGF21 may contribute, at least in part, to the glycemic benefits observed following combination therapy in patients with T2D.

BACKGROUND: Multiple inhaler triple therapy (MITT), comprising inhaled corticosteroids (ICS), long-acting beta-agonists (LABA), and long-acting muscarinic antagonists (LAMA), has been used as an escalation treatment for patients with chronic obstructive pulmonary disease (COPD). However, real-world use of MITT has not been investigated in Asia, including South Korea. This study reports baseline characteristics of patients with COPD initiated on MITT in South Korea, and their treatment patterns. Healthcare resource utilization (HRU) and costs associated with COPD exacerbations following MITT initiation were also assessed. METHODS: This was a retrospective cohort study using the South Korea National Health Insurance database (2014-2018). Included patients were ≥ 40 years, had a COPD diagnosis, were newly initiated on MITT and had ≥ 12 months' data both before (baseline) and after index date (the first day with overlapping supply of all MITT components). Treatment immediately before initiation and immediately following discontinuation of MITT were identified, and proportion of days covered (PDC) by MITT was calculated. HRU and costs (per person per year [PPPY]) associated with exacerbations were identified following MITT initiation; costs were calculated using the average 2020 exchange rate (0.0008 USD/KRW). RESULTS: Among 37,400 patients, the mean age was 69 (SD 10) years and 73% were males; 56% had ≥ 1 COPD exacerbation during the baseline period, with a mean of 2 (SD 5) events/year. ICS/LABA was the most frequent regimen prescribed immediately before initiation (37%) and immediately following discontinuation (41% of 34,264 patients) of MITT. At 3, 6, and 12 months from treatment initiation, mean PDC was 81%, 63% and 49%, respectively; median treatment duration was 102 days. The mean (95% confidence interval [CI]) number of total visits for severe COPD exacerbations was 0.77 PPPY (0.75-0.78); mean PPPY total healthcare costs were 2093 USD. CONCLUSIONS: Patients with COPD in South Korea experienced frequent exacerbations prior to MITT, and PDC by MITT was low. Patients may benefit from early optimization of COPD therapy, and greater emphasis on adherence to inhaled COPD therapy. Severe exacerbations were found to incur substantial costs; treatment alternatives that can reduce the rate of severe exacerbations are likely to minimize healthcare costs.

OBJECTIVE: Lymphatic filariasis is a serious public health issue. Recent studies showed that a single dosage of triple therapy (Ivermectin, Diethylcarbamazepine, and Albendazole) is more effective than dual therapy (Ivermectin plus Albendazole or Diethylcarbamazepine plus Albendazole) for clearing microfilaria from the blood. We aimed to evaluate the efficacy and safety of triple therapy versus dual therapy in patients infected with microfilaria and communities endemic to lymphatic filariasis. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, EMBASE, SCOPUS, Cochrane Central Register of Controlled Trials, and Web of Science until 24th June 2021. We included randomized control trials that compared triple with dual therapy given to patients with lymphatic filariasis or endemic communities. This study was registered with PROSPERO (CRD42021266724). RESULTS: We included eight articles after the screening process. Triple therapy caused more clearance of microfilaria in the blood (RR: 1.52; 95% CI: 1.15, 2.02; p = 0.003), while dual therapy caused more clearance of the circulating filariae antigen in the blood (RR: 0.76; 95% CI: 0.65, 0.88; p = 0.0003), both 12 months after drug administration. The triple therapy had a similar adverse effect compared with the dual therapy group. CONCLUSION: Based on the greater efficacy in the clearance of microfilaria and the safety of triple therapy, it constitutes a better strategy for the eradication programs of lymphatic filariasis in endemic regions. However, further studies are needed to confirm our results.

BACKGROUND: Helicobacter pylori (H. pylori) is a highly prevalent organism that can induce an inflammatory state in the upper gastrointestinal tract and lead to complications such as peptic ulcer and gastric cancer. The treatment regime is complicated, and mild-to-moderate adverse effects are common, making patient compliance a key determinant of successful eradication. One attractive strategy is to leverage on technology-enhanced communication (TEC) strategies. However, the current data on the efficacy of TEC modalities in improving H. pylori eradication are limited. This is the first meta-analysis evaluating its effectiveness to the best of our knowledge. Thus, it is essential to evaluate the current body of evidence to learn the impact of TEC initiatives. METHODS: A literature search was done on PubMed, World of Science, and Embase. A total of 9 studies variably reported on compliance rate, eradication rate, adverse effect rate, symptom relief, patient satisfaction, treatment cost, patient disease awareness, and follow-up rates. RESULTS: This meta-analysis showed that TEC initiatives significantly improve patient compliance (OR 4.52, 95% CI 2.09 - 9.77, p < .01) and eradication rate (OR 1.98, 95% CI 1.34 - 2.93, p < .01) but not adverse effect rate (OR 0.65, 95% CI [0.27 - 1.57], p = .34). Due to the small number of studies and population sample, patient satisfaction, symptom relief, treatment costs, disease awareness, and follow-up rates were assessed qualitatively. CONCLUSION: TEC initiatives effectively improve compliance to the H. pylori eradication regime and increase the eradication rate.
