ABSTRACT

BACKGROUND: Alcohol use disorder (AUD) is the most common substance use disorder and is characterized by heavy alcohol use and the inability to control drinking. This study sought to compare the rate, timing, length, and total costs of hospital readmissions among cancer survivors with and without AUD. METHODS: We used the Nationwide Readmissions Database in 2017 and 2018 in this cohort study. Cancer survivors with an AUD diagnosis during their index hospitalization were included in the exposure group. Propensity score matching was used to identify cancer survivors without AUD for the control group. The primary outcome was all-cause readmission, and secondary outcomes included days to, length of, and total cost of readmission. Outcomes were measured after 90 and 180 days of follow-up. Logistic regression was used to measure the likelihood of readmission, and negative binomial regression and gamma regression were used for the other outcomes. RESULTS: Of 485,962 cancer survivors, 13,953 (2.9%) had co-occurring AUD. Cancer survivors with AUD had slightly higher odds of 90-day (odds ratio, 1.14; 95% CI, 1.06-1.22) and 180-day (odds ratio, 1.11; 95% CI, 1.05-1.18) readmission compared with those without AUD. Cancer survivors with AUD who were readmitted after 90 days also had higher readmission costs ($3,785 vs $3,376; P=.03). No differences in time to and length of readmission were observed between groups. The odds of readmission were higher among cancer survivors with AUD irrespective of age and type of cancer. Male, but not female, cancer survivors with AUD were more likely than those without AUD to be readmitted in both follow-up periods. CONCLUSIONS: This population-based cohort study of cancer survivors in the United States found that AUD is associated with higher 90- and 180-day readmission rates and higher related health care costs after 90 days of follow-up. Hospitalized cancer survivors with AUD may benefit from addiction treatment and discharge planning that addresses their co-occurring AUD.

ABSTRACT

Importance: Sulfonylureas are frequently used as add-on to metformin in type 2 diabetes (T2D), and individual sulfonylurea agents carry different risks of cardiovascular disease. Sulfonylureas' different affinities to cardiac mitochondrial adenosine triphosphate-sensitive potassium (mitoKATP) channels have been speculated to account for the intraclass difference in cardiovascular risk from in vitro and ex vivo studies; however, this hypothesis has not been assessed in a general population with diabetes receiving sulfonylureas added to metformin. Objective: To compare the risk of myocardial infarction (MI), ischemic stroke, or cardiovascular death in patients with T2D treated with mitoKATP channel high-affinity sulfonylureas and low-affinity sulfonylureas as add-on to metformin. Design, Setting, and Participants: This is a new-user, active-comparator, and propensity score-matched cohort study with analysis of the Taiwanese Diabetes Mellitus Health Database from 2006, to 2017. Data analysis was performed from August 2020 to July 2021. Exposures: Cardiac mitoKATP channel high-affinity (glyburide and glipizide) and low-affinity (gliclazide and glimepiride) sulfonylureas combined with metformin. Main Outcomes and Measures: Primary outcome was major adverse cardiovascular events (MACEs), a composite of cardiovascular death or hospitalization for either MI or ischemic stroke. Secondary outcomes included individual MACE components, heart failure, arrhythmia, all-cause mortality, and severe hypoglycemia. Cox proportional hazards models were used to estimate adjusted hazard ratios (aHRs). Results: Each sulfonylurea group comprised 53 714 patients (mean [SD] age, 54.7 [12.1] years; 31 962 men [59.5%]). MitoKATP channel high-affinity sulfonylureas vs low-affinity sulfonylureas when combined with metformin were associated with an increased risk of MACE (aHR, 1.18; 95% CI, 1.03-1.34), MI (aHR, 1.34; 95% CI, 1.04-1.73), all-cause mortality (aHR, 1.27; 95% CI, 1.03-1.57), and severe hypoglycemia (aHR, 1.82; 95% CI, 1.58-2.10), but not with increased risks of ischemic stroke, cardiovascular death, arrhythmia, and heart failure. The duration analyses revealed the highest MACE risk during 1 to 90 days after initiation of mitoKATP channel high-affinity sulfonylureas (aHR, 6.06; 95% CI, 4.86-7.55). Conclusions and Relevance: Use of mitoKATP channel high-affinity sulfonylureas vs low-affinity sulfonylureas was associated with an increased MACE risk in patients with T2D concomitantly receiving metformin, suggesting that high-affinity blockage of the mitoKATP channels could account for sulfonylurea-associated MACEs.

ABSTRACT

OBJECTIVE: Previous studies have revealed an intraclass difference in major adverse cardiovascular events (MACE) among sulfonylureas. In vitro and ex vivo studies reported several sulfonylureas to exhibit high-affinity blockage of cardiac mitochondrial ATP-sensitive potassium (mitoKATP) channels and could interfere with ischemic preconditioning, the most important mechanism of self-cardiac protection. However, no studies have examined whether these varying binding affinities of sulfonylureas could account for their intraclass difference in MACE. We compared mitoKATP channel high-affinity versus low-affinity sulfonylureas regarding the MACE risk in real-world settings. RESEARCH DESIGN AND METHODS: Using the Taiwan nationwide health care claims database, patients with type 2 diabetes initiating sulfonylurea monotherapy between 2007 and 2016 were included in the cohort study. A total of 33,727 new mitoKATP channel high-affinity (glyburide and glipizide) and low-affinity (gliclazide and glimepiride) sulfonylurea users, respectively, were identified after 1:1 propensity score matching. Cox proportional hazard models were used to estimate adjusted hazard ratios (aHRs) and 95% CI. RESULTS: MitoKATP channel high-affinity sulfonylureas were associated with a significantly increased risk of three-point MACE (aHR 1.21 [95% CI 1.03-1.44]), ischemic stroke (aHR 1.23 [95% CI 1.02-1.50]), and cardiovascular death (aHR 2.61 [95% CI 1.31-5.20]), but not with that of myocardial infarction (aHR 1.04 [95% CI 0.75-1.46]). The duration-response analyses revealed the highest MACE risk to be within 90 days of therapy (aHR 4.67 [95% CI 3.61-6.06]). CONCLUSIONS: Cardiac mitoKATP channel high-affinity sulfonylureas were associated with an increased MACE risk compared with low-affinity sulfonylureas in a nationwide population with diabetes.

ABSTRACT

BACKGROUND: Despite multiple available fixed-dose combinations (FDCs) of inhaled long-acting ß2-agonists (LABAs) plus long-acting muscarinic antagonists (LAMAs) and LABAs plus inhaled corticosteroids (ICS) for COPD, uncertainty remains regarding their comparative effects. RESEARCH QUESTION: Can comparative effectiveness and safety of LABA plus LAMA (LABA/LAMA) and LABA plus ICS (LABA/ICS) FDCs vary by different individual components of the dual combinations in COPD? STUDY DESIGN AND METHODS: We conducted a new user, propensity score-inverse probability of treatment weighting cohort study to compare the effectiveness and safety of two frequently used LABA/LAMA FDCs (indacaterol plus glycopyrronium [IND/GLY] and vilanterol plus umeclidinium [VI/UMEC]) vs three commonly prescribed LABA/ICS FDCs (salmeterol plus fluticasone propionate [SAL/FP], formoterol fumarate plus budesonide [FF/BUD], and formoterol fumarate plus beclomethasone dipropionate [FF/BDP]) using the Taiwanese nationwide health care claims from 2014 through 2017. The primary effectiveness outcome was the annual moderate to severe exacerbation rate, and safety outcomes included risks of severe pneumonia and cardiovascular disease requiring hospitalization. Weighted generalized linear mixed models and Cox proportional hazard models were used to assess the effectiveness and safety outcomes, respectively. RESULTS: Patients with COPD initiating IND/GLY and VI/UMEC showed an 11% (incidence rate ratio [IRR], 0.89; 95% CI, 0.80-0.98) and 20% (IRR, 0.80; 95% CI, 0.71-0.90) reduced annual rate of moderate to severe exacerbations, respectively, than those initiating SAL/FP, but showed a similar rate as those initiating FF/BUD or FF/BDP. Both LABA/LAMA FDCs, compared with SAL/FP and VI/UMEC vs FF/BDP, were associated with a 27% (hazard ratio [HR], 0.73; 95% CI, 0.59-0.90) to 42% (HR, 0.58; 95% CI, 0.48-0.70) reduced pneumonia risk. Cardiovascular risk was comparable in five groups. An intraclass difference existed in rates of moderate to severe COPD exacerbation and risks of pneumonia among LABA/ICS FDCs, but not between LABA/LAMA FDCs. INTERPRETATION: Both LABA/LAMAs vs SAL/FP are associated with a lower exacerbation rate and pneumonia risk, but exhibit similar effectiveness and safety outcomes compared with FF/BDP or FF/BUD, suggesting that comparative effects may differ by individual components of the dual therapies in COPD.

ABSTRACT

BACKGROUND: Exacerbation of chronic obstructive pulmonary disease (COPD) severely impacts the quality of life and causes high mortality and morbidity. COPD is involved with systemic and pulmonary inflammation, which may be attenuated with antidiabetic agents exerting anti-inflammatory effects. Real-world evidence is scant regarding the effects of antidiabetic agents on COPD exacerbation. Accordingly, we conducted a disease risk score (DRS)-matched nested case-control study to systemically assess the association between each class of oral hypoglycemic agents (OHAs) and risk of severe COPD exacerbation in a nationwide COPD population co-diagnosed with diabetes mellitus (DM). METHODS: We enrolled 23,875 COPD patients receiving at least one OHA for management of DM by analyzing the Taiwan National Health Insurance claims database between January 1, 2000, and December 31, 2015. Cases of severe exacerbation were defined as those who had the first hospital admission for COPD. Each case was individually matched with four randomly-selected controls by cohort entry date, DRS (the estimated probability of encountering a severe COPD exacerbation), and COPD medication regimens using the incidence density sampling approach. Conditional logistic regressions were performed to estimate odds ratios (OR) of severe COPD exacerbation for each type of OHAs. RESULTS: We analyzed 2700 cases of severe COPD exacerbation and 9272 corresponding controls after DRS matching. Current use of metformin versus other OHAs was associated with a 15% (adjusted OR [aOR], 0.85; 95% confidence interval [CI] 0.75-0.95) reduced risk of severe COPD exacerbation, whereas the reduced risk was not observed with other types of antidiabetic agents. When considering the duration of antidiabetic medication therapy, current use of metformin for 91-180 and 181-365 days was associated with a 28% (aOR, 0.72; 95% CI 0.58-0.89) and 37% (aOR, 0.63; 95% CI 0.51-0.77) reduced risk of severe COPD exacerbation, respectively. Similarly, 91-180 days of sulfonylureas therapy led to a 28% (aOR, 0.72; 95% CI 0.58-0.90) lower risk, and longer treatments consistently yielded 24-30% lower risks. Current use of thiazolidinediones for more than 181 days yielded an approximately 40% decreased risk. CONCLUSIONS: Duration-dependent beneficial effects of current metformin, sulfonylurea, and thiazolidinedione use on severe COPD exacerbation were observed in patients with COPD and DM.

ABSTRACT

PURPOSE: To evaluate whether concomitant use of amiodarone and sulfonylureas is associated with an increased risk of serious hypoglycemia. METHODS: We conducted two nested case-control studies by analyzing the Taiwan National Health Insurance Research Database from 2008 to 2013 among diabetic patients continuously receiving sulfonylureas. Cases were defined as patients with severe hypoglycemia and those with a composite outcome of severe hypoglycemia, altered consciousness, and fall-related fracture in the first and second study, respectively. In both studies, each case was individually matched up to 10 randomly-selected controls. Conditional logistic regressions were employed to estimate odds ratios (ORs). RESULTS: We identified 1343 cases and 11 597 controls as well as 2848 cases of composite events and 24 808 controls among 46 317 sulfonylurea users. Concurrent use of amiodarone with sulfonylureas was associated with a 1.56-fold (95% CI: 0.98-2.46) increased risk of severe hypoglycemia, despite not statistically significant. Notably, an approximately 2-fold increased risk of severe hypoglycemia was observed with amiodarone therapy lasting for >180 days (adjusted OR: 2.08; 95% CI: 1.01-4.30) or at a daily dose greater than 1 defined daily dose (adjusted OR: 2.21; 95% CI: 1.25-3.91) when concurrently administrating sulfonylureas. A significantly increased risk of hypoglycemia-related composite events was also found with amiodarone concurrently used with sulfonylureas (adjusted OR: 1.59; 95% CI: 1.13-2.24). CONCLUSIONS: Concurrent use of amiodarone and sulfonylureas is associated with an increased risk of serious hypoglycemia among diabetic patients, with an elevated risk for amiodarone used in a long-term or at a high daily dose.

ABSTRACT

AIMS: Evidence on acute respiratory failure (ARF) from antipsychotics is scant, and only 1 population-based study examined this drug safety issue in chronic obstructive pulmonary disease patients. Antipsychotics have been frequently prescribed off-label in adults, but whether antipsychotic use carries an increased ARF risk among adult patients is uncertain. METHODS: We adopted a nested case-control study analysing 716 493 adults aged ≥20 years, identified from the Taiwan nationwide healthcare claims records between January 2000 and December 2013. Among the study cohort, 7084 adults with ARF and 12,785 disease risk scored-matched randomly selected controls were analysed. Multivariable logistic regression models were employed to estimate odds ratios of ARF with antipsychotic usages. RESULTS: Current, recent, and recent past use of antipsychotics was associated with a 2.33-fold (95% confidence interval [CI] = 2.06-2.64), 1.79-fold (95% CI = 1.43-2.25) and 1.41-fold (95% CI = 1.20-1.66) increased risk of ARF, respectively, compared with nonuse, while antipsychotics discontinued >90 days carried no risk. A dose-dependent association was observed with current therapy of antipsychotics (test for trend, P < .001), in which antipsychotic use at >1 defined daily dose yielded the highest risk of 6.53-fold (95% CI = 3.33-12.79). The findings were robust to using carbamazepine as an active comparator. CONCLUSION: Antipsychotic use was associated with an increased risk of ARF in adult patients. The risk was dose-dependent and markedly higher with current use of antipsychotic agents at doses of 1 defined daily dose and above, <10% of this cohort. Physicians should be vigilant about any respiratory symptoms in patients currently receiving antipsychotics at such dose.

ABSTRACT

Inhaled long-acting bronchodilators, including long-acting ß2 agonists (LABAs) and long-acting muscarinic antagonists (LAMAs) are the mainstay therapy in the treatment of chronic obstructive pulmonary disease (COPD), a disease that poses a heavy burden on morbidity and mortality worldwide. Use of LABAs and LAMAs in patients with COPD, however, has been concerned about an increased risk of adverse cardiovascular events, despite inconsistent findings reported from randomized controlled trials (RCTs) and observational studies. In this review, we detailed the relevant evidence generated from RCTs and observational studies with respect to the risk of cardiovascular disease with use of LABAs and LAMAs in management of COPD, and analyzed the contradictory findings in the literature, as well as recommended future research directions to clear the air regarding the cardiovascular safety of inhaled long-acting bronchodilators.

ABSTRACT

OBJECTIVE: To examine the risk of cardiovascular disease (CVD) from tiotropium added to inhaled long-acting ß2 agonists (LABAs) and inhaled corticosteroids (ICSs) in a nationwide population with chronic obstructive pulmonary disease (COPD). PATIENTS AND METHODS: This nested case-control study included 65,966 patients with COPD treated with LABAs and ICSs identified from the Taiwan nationwide health care claims database from January 1, 2007, through June 30, 2011. Cases were all patients with a first primary diagnosis of ischemic heart disease, heart failure, stroke, or arrhythmia from inpatient or emergency care settings during follow-up, and each was matched with 4 disease risk score-matched controls from risk sets. The use of tiotropium in the year before the index/event date was measured, stratified by duration since therapy initiation, concomitant COPD medications, and dosage form. Conditional logistic regression models were used to estimate odds ratios of the CVD risk from add-on tiotropium therapy. RESULTS: From the study cohort, with a mean age of 70.3 years (interquartile range, 61.8-79.4 years), 3188 CVD cases (incidence rate, 6.2 [95% CI, 6.0-6.4] cases per 100 person-years) and 12,349 matched controls were identified. The new use of tiotropium was associated with a 1.88-fold (95% CI, 1.44-2.46) increased CVD risk within 30 days of therapy initiation, and the association was sustained up to 60 days after treatment initiation (adjusted odds ratio, 1.71; 95% CI, 1.08-2.70). The risk persisted across all tiotropium regimens, with a case-crossover analysis, and in comparison with new add-on theophylline therapy. CONCLUSION: Tiotropium newly added to LABA/ICS combination therapy was associated with an increased cardiovascular risk in patients with COPD.

ABSTRACT

Importance: The associations between cardiovascular disease (CVD) and inhaled long-acting ß2-agonists (LABAs) or long-acting antimuscarinic antagonists (LAMAs) in chronic obstructive pulmonary disease (COPD) are greatly debated. Pivotal and relevant randomized clinical trials included prior LABA or LAMA users and excluded patients with baseline CVD; therefore, cardiovascular events arising from first-time LABA or LAMA use, if any, could not be observed. There is an urgent need to examine whether new use of and duration since initiating LABAs and LAMAs could act as important determinants of cardiovascular events. Objective: To investigate risk of CVD associated with LABAs and LAMAs, focusing on the initiation and duration of LABA and LAMA therapies. Design, Setting, and Participants: This nested case-control study included 284 220 LABA-LAMA-naïve patients with COPD at least 40 years old (mean age, 71.4 years; 68.9% men), retrieved from the Taiwan National Health Insurance Research Database for health care claims from 2007 to 2011. Exposure: LABA or LAMA use was measured in the year preceding the event or index date, stratified by duration since initiation of LABA or LAMA treatment, new and prevalent users, concomitant COPD medications, and individual agents. Main Outcomes and Measures: Cases with inpatient or emergency care visits for coronary artery disease, heart failure, ischemic stroke, or arrhythmia were identified and individually matched to 4 randomly selected controls. Conditional logistic regressions were performed to estimate odds ratios of CVD from LABA and LAMA treatment. Results: During a mean follow-up of 2.0 years, 37 719 patients with CVD (mean age, 75.6 years; 71.6% men) and 146 139 matched controls (mean age, 75.2 years; 70.1% men) were identified. New LABA and LAMA use in COPD was associated with a 1.50-fold (95% CI, 1.35-1.67; P < .001) and a 1.52-fold (95% CI, 1.28-1.80; P < .001) increased cardiovascular risk within 30 days of initiation, respectively, whereas the risk was absent, or even reduced with prevalent use. Individual LABA agents, LAMA dosage forms, and concomitant COPD regimens did not differ in the CVD risks. The risk persisted in an alternative case-crossover study and remained across subgroups without CVD history or prior exacerbations. Conclusions and Relevance: New initiation of LABAs or LAMAs in patients with COPD is associated with an approximate 1.5-fold increased severe cardiovascular risk, irrespective of prior CVD status and history of exacerbations.
