RESUMO
Of the patients with asthma, 20% to 25% progress to severe symptoms, resulting in poor quality of life and increased episodes of exacerbation. There is a broad range of drugs used for asthma; the most used medications for severe asthma are inhaled glucocorticoids with or without long-acting ß-agonists. Systemic glucocorticoids and other treatments as add-on therapies are also given as needed. Chronic glucocorticoid use is associated with numerous adverse effects, including diabetes mellitus, osteoporosis, anxiety, depression, and cataracts. The occurrence of these side effects has been reduced because of the emergence of new biological therapies. One such treatment is dupilumab, which helps in the reduction of type 2 inflammation involved in the pathophysiology of asthma. We conducted a literature review to assess the efficacy, adverse effects, and pharmacological benefits of dupilumab in glucocorticoid-dependent asthma. In most randomized controlled trials, dupilumab has shown significant efficacy and safety profile in patients with severe asthma with corticosteroid dependence. Associated adverse effects such as injection site reaction and transient eosinophilia have been reported. Our review of the literature indicates that dupilumab has proven to improve lung function, reduce the rate of asthma exacerbations, and reduce the use of corticosteroids.

PURPOSE: Cardiovascular adverse events (CVAEs) are common adverse effects of first-generation Bruton tyrosine kinase inhibitors (BTKis) and limit their use considerably. This led to the development of second-generation BTKis-acalabrutinib and zanubrutinib-which are more selective, potent, and presumed to have better safety profiles than the previous group of medications. However, there have been sporadic reports of CVAEs associated with second-generation BTKis in clinical practice. To address this issue, a comprehensive meta-analysis to pool the documented CVAEs was performed, including major hemorrhage, any bleeding, atrioventricular block, atrial fibrillation/flutter, pericardial effusion, pericarditis, heart failure, cardiac arrest, myocardial infarction, hypertension, hypotension, and stroke. This meta-analysis incorporated 8 studies. Among these, 6 were Phase III trials and 2 were Phase II trials. These studies collectively enrolled a total of 2938 patients. METHODS: Multiple databases, including PubMed, MEDLINE, Cochrane Library, Scopus, and EMBASE, were systematically searched for relevant clinical trials from inception through January 14, 2023. The effect measure used was odds ratio (OR) and 95% CI. FINDINGS: Of a total of 1774 studies identified during the initial database search, 8 were included in the meta-analysis. The incidence of overall and cardiovascular mortality was comparable between the 2 groups. There were no significant differences observed for cardiovascular mortality (OR = 0.36; 95% CI, 0.08-1.65; n = 2588; I2 = 45%; P = 0.19). Similar results were found for all-cause mortality (OR = 0.85; 95% CI, 0.67-1.07), any bleeding (OR = 1.90; 95% CI, 0.88-4.09), major bleeding (OR = 1.07; 95% CI, 0.65-1.76), atrioventricular block (OR = 0.74; 95% CI, 0.15-3.68), atrial fibrillation/flutter (OR = 0.74; 95% CI, 0.37-1.50), and other CVAEs associated with second-generation BTKis. IMPLICATIONS: Based on the available evidence, there is no indication of worse cardiovascular outcomes or superiority of second-generation BTKis compared with standard treatments in terms of safety profile. However, additional large-scale controlled trials are needed to provide robust support for the superior tolerability of new-generation BTKis.

BACKGROUND: Chronic steroid (CS) therapy was reportedly linked to increased vascular complications following percutaneous coronary intervention. However, its association with vascular complications after transcatheter aortic valve replacement (TAVR) remained uncertain, with conflicting results being reported. OBJECTIVE: The authors aimed to compare the rate of vascular complications and outcomes between patients with and without CS use after TAVR. METHODS: The authors conducted a comprehensive literature search in PubMed, Embase, and Cochrane databases from their inception until 18th April 2022 for relevant studies. Endpoints were described according to Valve Academic Research Consortium-2 definitions. Effect sizes were pooled using DerSimonian and Laird random-effects model as risk ratio (RR) with 95% CI. RESULTS: Five studies with 6136 patients undergoing TAVR were included in the analysis. The included studies were published between 2015 and 2022. The mean ages of patients in both study groups were similar, with the CS group averaging 80 years and the nonsteroid group averaging 82 years. Notably, a higher proportion of patients in the CS group were female (56%) compared to the nonsteroid group (54%). CS use was associated with a significantly higher risk of major vascular complications (12.5 vs. 6.7%, RR 2.32, 95% CI: 1.73-3.11, P <0.001), major bleeding (16.8 vs. 13.1%, RR 1.61, 95% CI: 1.27-2.05, P <0.001), and aortic annulus rupture (2.3 vs. 0.6%, RR 4.66, 95% CI: 1.67-13.01, P <0.001). There was no significant difference in terms of minor vascular complications (RR 1.43, 95% CI: 1.00-2.04, P =0.05), in-hospital mortality (2.3 vs. 1.4%, RR 1.86, 95% CI: 0.74-4.70, P =0.19), and 30-day mortality (2.9 vs. 3.1%, RR 1.14, 95% CI: 0.53-2.46, P =0.74) between both groups. CONCLUSION: Our study showed that CS therapy is associated with increased major vascular complications, major bleeding, and annulus rupture following TAVR. Further large multicenter studies or randomized controlled trials are warranted to validate these findings.

BACKGROUND: Leadless pacemakers (LP) and transvenous pacemakers (TVP) are two stable pacing platforms currently available in clinical practice. Observational data show mixed results with regards to their comparative safety. This meta-analysis was aimed to evaluate the comparative safety of LP over TVP. METHODS: The study protocol was registered in PROSPERO registry (CRD42022325376). Six databases were searched for published literature from inception to April 12, 2022. RevMan 5.4.1 was used for statistical analysis. Odds ratio (OR) and mean difference were used to estimate the outcome with a 95% confidence interval (CI). RESULTS: A total of 879 studies were imported from the databases. Among these, 41 papers were screened for full text and 17 meet the inclusion criteria. Among them, pooled results showed 42% lower odds of occurrence of complications in the LP group (OR 0.58, CI 0.42-0.80) compared to TVP group. Notably, 70% lower odds of device dislodgment (OR 0.30, CI 0.21-0.43), 46% lower odds of re-intervention (OR 0.54, CI 0.45-0.64), 87% lower odds of pneumothorax (OR 0.13, CI 0.03-0.57), albeit, 2.65 times higher odds of pericardial effusion (OR 2.65, CI 1.49-4.70) were observed in the LP group. CONCLUSIONS: This meta-analysis showed LP to be a significantly safer modality compared to TVP, in terms of re-intervention, device dislodgment, pneumothoraxes, and overall complications. However, there were higher rates of pericardial effusion in the LP group. There was a diverse number of patients included, and all studies were observational. Randomized trials are needed to validate our findings.

Transthyretin amyloid cardiomyopathy disease burden is increasing daily due to advancements in diagnostic and imaging modalities in the modern world. Tafamidis is one of many therapeutic options. The main objective of this review is to study the role of Tafamidis in slowing the progression of transthyretin cardiomyopathy (TTR-CM) by analyzing randomized controlled trials (RCTs) and non-RCTs of Tafamidis. We searched for published papers of Tafamidis in the English language in electronic databases like Google Scholar, PubMed, Cochrane Library, and PubMed Central. We imported the resulting articles from our search to Mendeley software. Four reviewers removed the duplicates and performed title and abstract screening of the articles. The same reviewers obtained the full-text of relevant articles and did full-text screening based on eligibility criteria. Finally, five reviewers performed a quality assessment of RCTs using the Cochrane risk of bias assessment and of non-RCTs by a checklist prepared by Downs and Black. Any disagreements about any process were resolved by a discussion with other authors. One RCT and five non-RCTs of Tafamidis were included in this systematic review. From the non-RCTs, stability was observed in different parameters like echocardiographic findings, cardiac biomarkers, and ECG in patients with transthyretin cardiomyopathy during the study duration with Tafamidis. ATTR-ACT (Tafamidis in Transthyretin Cardiomyopathy Clinical Trial) trial demonstrated reduction of cardiovascular events and all-cause mortality in the Tafamidis group in comparison to placebo. In both RCT and non-RCTs, Tafamidis was established as a safe and tolerable drug for patients with TTR-CM. Our study proved the role of Tafamidis in reducing cardiovascular events, all-cause mortality, and the progression of cardiac disease in TTR-CM patients. In addition to five non-RCTs, current evidence is based on the findings of only one RCT of Tafamidis. Hence, evidence from additional RCTs is required to strongly support the stability of parameters like echocardiographic findings, cardiac biomarkers, and ECG with Tafamidis use.
