Abstract

Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of global mortality, primarily driven by an abnormal inflammatory response to harmful particles and gases. This review explores the epigenetic mechanisms underlying COPD pathogenesis and their therapeutic implications. A comprehensive literature review was conducted, analyzing recent findings on DNA methylation, histone modifications, and noncoding RNAs (ncRNAs) in COPD. Key studies highlighting the impact of these epigenetic changes on inflammation, cellular responses, and disease progression were evaluated. Our review highlights that epigenetic modifications, such as DNA methylation and histone modifications, significantly impact gene expression without altering the DNA sequence. Cigarette smoking has been shown to influence both DNA methylation and histone acetylation, leading to inflammatory responses and the the exacerbation of COPD. These modifications contribute to chronic inflammation and disease progression, with alterations in histone acetylation, methylation, and phosphorylation playing critical roles in COPD pathogenesis. The interplay between epigenetic changes and environmental factors, particularly tobacco smoke, reveals a complex mechanism driving COPD progression. Aberrant gene expression linked to these epigenetic modifications suggests potential disease severity and progression biomarkers. Targeting these alterations offers novel therapeutic strategies. Emerging treatments, such as quercetin and theophylline, promise to restore normal cellular functions and effectively manage COPD. Future research should focus on elucidating these mechanisms further and developing targeted therapies to mitigate the impact of epigenetic modifications on COPD.

Abstract

Abstract: Tocilizumab is an anti-IL-6 which is recommended as cytokine release syndrome therapy in the treatment of Covid-19. One of the side effects of tocilizumab that can occur is hepatotoxicity, from mild elevated transaminases to severe drug-induced liver injury (DILI). Currently, research related to tocilizumab hepatotoxicity and the risk factors affecting Covid-19 patients is limited and still needs to conduct. This research is an observational study with cross-sectional design. Data collection was carried out retrospectively using secondary data obtained from medical records department, patients with Covid-19 at Universitas Indonesia Hospital in 2020-2021. Patients confirmed with positive Covid-19 receiving Tocilizumab therapy in medical record were included in this study. Patient demographics, clinical diagnoses, laboratory examinations, history of others medication were also reviewed. Patients with less than 18 years old, incomplete medical record data, and referred to other hospitals were excluded. The sampling technique used was total sampling, namely all patients who met the inclusion criteria were taken as subject in this research. Chi-square test was used to analyze the relationship between each risk factors and the incidence of elevated transaminases. The results of Chi-square test showed that several risk factors significantly increased the incidence of elevated transaminases in patients given tocilizumab therapy, including age, obesity, diabetes mellitus, and ceftriaxone as antibiotic therapy.

Abstract

Introduction: After completion of pulmonary tuberculosis (TB) treatment, some people may continue to experience respiratory issues that can progress into post-TB lung disease (PTLD). Individuals with PTLD exhibit suboptimal nutritional status. The loss of appetite is a significant factor influencing nutritional status. Zinc plays a role in hunger control.  Lack of zinc reduces taste sensitivity and food intake. This study examined the relationship between zinc intake and appetite in patients with PTLD at Persahabatan National Respiratory Referral Hospital, Jakarta. Methods: This cross-sectional study was conducted at Persahabatan National Respiratory Referral Hospital, Jakarta, from November 2024 to March 2025. Eighty-five adult patients with PTLD were included. Zinc intake was assessed by a semi-quantitative food frequency questionnaire (SQ-FFQ) and analyzed by NutriSurvey software. Appetite was measured using the visual analog scale (VAS) for appetite. Results: A total of 85 subjects participated in the study, comprising 78.8% males and 21.2% females. The average daily zinc intake was 4.4 mg/day, and 92.9% of the subjects had zinc intake below the recommended dietary allowance (RDA). The average VAS appetite score was 70 mm. A significant positive correlation was found between zinc intake and appetite, indicating that a decrease in zinc intake might result in a reduced appetite (r=0.266, p=0.014). Conclusion: Zinc intake is positively associated with appetite in patients with PTLD. Therefore, zinc intake monitoring is essential for supporting nutritional recovery and lung function in PTLD.
