RESUMO
Sarcoidosis can be presented as cardiac sarcoidosis (CS), which is challenging to diagnose due to its clinical silence. Ventricular arrhythmias and atrioventricular blocks can be fatal and cause sudden death in patients with cardiac sarcoidosis. Five percent of sarcoidosis patients have clinically evident cardiac sarcoidosis. However, autopsy reports and imaging studies have shown a higher prevalence of cardiac involvement. Early recognition is important to prevent such detrimental consequences. Cardiac sarcoidosis is increasingly being diagnosed owing to increased awareness among physicians and new diagnostic tools like MRI and positron emission tomography (PET) scan replacing traditional endomyocardial biopsy. A definitive diagnosis of CS remains challenging due to the non-specific clinical findings that can present similar symptoms of common cardiac disease; therefore, the imaging and biopsies are substantial for diagnosis confirmation. Pharmacological and Implantable devices are two main therapeutic approaches in cardiac sarcoidosis, in which steroids and pacemaker therapy have shown better outcomes. This review summarizes the available data related to the prevalence, prognosis, diagnosis, and management of cardiac sarcoidosis.
RESUMO
Background: There is an increased trend of e-cigarette but the toxic effects of e-cigarette metabolites are not widely studied especially in liver disease. Hence, we aimed to evaluate the prevalence and patterns of recent e-cigarette use in a nationally representative sample of US adults and adolescents and its association amongst respondents with liver disease. Methods: We conducted a retrospective cross-sectional study using National Health and Nutrition Examination Survey (NHANES) database from 2015 to 2018. The self-reported NHANES questionnaire was used to assess liver disease (MCQ160L, MCQ170L and MCQ 510 (a-e)), e-cigarette use (SMQ900) and traditional smoking status (SMQ020 or SMQ040). We conducted univariate analysis and multivariable logistic regression models to predict the association of e-cigarette use, traditional smoking and dual smoking amongst the population with liver disease. Results: Out of total 178,300 respondents, 7,756 (4.35%) were e-cigarette users, 48,625 (27.27%) traditional smoking, 23,444 (13.15%) dual smoking and 98,475 (55.23%) non-smokers. Females had a higher frequency of e-cigarette use (49.3%) compared to dual (43%) and traditional smoking (40.8%) (P < 0.0001). Respondents with a past history of any liver disease have lower frequency of e-cigarette use compared to dual and traditional smoking, respectively (2.4% vs. 6.4% vs. 7.2%; P < 0.0001). In multivariate logistic regression models, we found that e-cigarette users (odds ratio (OR): 1.06; 95% confidence interval (CI): 1.05 - 1.06; P < 0.0001) and dual smoking (OR: 1.50; 95% CI: 1.50 - 1.51; P < 0.0001) were associated with higher odds of having history of liver disease compared to non-smokers. Conclusion: Our study found that despite the low frequency of e-cigarette use in respondents with liver disease, there was higher odds of e-cigarette use amongst patients with liver disease. This warrants the need for more future prospective studies to evaluate the long-term effects and precise mechanisms of e-cigarette toxicants on the liver.
