Evaluation of safety and effectiveness of remdesivir in treating COVID-19 patients after emergency use authorization study.

Background: This study aimed to determine the real-world safety and effectiveness of remdesivir in hospitalized adult COVID-19 patients with moderate-to-critical disease in Indonesia. Methods: A multicenter, retrospective cohort study was conducted at four COVID-19 referral hospitals in Jakarta. A total of 587 patients were included, of whom 243 received remdesivir within 72 h of admission. The safety endpoints were the proportions of patients with any adverse event (AE), any grade 3 AE, and AE of each system organ class. The effectiveness endpoints were ICU admission >24 h from baseline, live discharge and mortality at day 14, live discharge and mortality at day 28, and virologic conversion. Patients who received remdesivir within 72 h of admission were considered the treatment group, and those who did not were the control group. Multivariate adjustments were performed using a modified Poisson regression. Results: The study found no significant differences in safety endpoints between the two groups. However, the effectiveness endpoints showed that remdesivir was associated with a decreased risk of ICU admission >24 h from baseline (RR 0.71, 95% CI 0.52-0.96), an increased probability of live discharge at day 14 (RR 1.37, 95% CI 1.08-1.74), and an increased probability of live discharge at day 28 (RR 1.28, 95% CI 1.05-1.57). The rate of virologic conversion was not significantly different between the two groups. Conclusion: The study concludes that remdesivir is safe and effective in the treatment of moderate-to-critical COVID-19 in a real-world setting in Indonesia.

Severe acute respiratory syndrome coronavirus-2 antibody response after Moderna vaccine booster on healthcare providers.

INTRODUCTION: As an endeavor to control SARS-CoV-2 infection, the Moderna vaccine booster was given to healthcare workers to prevent reinfection and reduce the risk of complications from COVID-19. A heterologous booster vaccine is also thought to provide better protection against the current SARS-CoV-2 variants of concern. However, research that evaluates the effectiveness of the Moderna vaccine booster and the resulting SARS-CoV-2 antibody concentration is needed. OBJECTIVE: To evaluate the concentration of SARS-CoV-2 antibodies after the Moderna vaccine booster and the severity of SARS-CoV-2 infection before and after the Moderna vaccine booster. RESULTS: A total of 93 healthcare providers who received Moderna vaccine booster were included in the study. Examination of antibody concentration 3 months after the booster showed an average concentration of 10081.65 U/mL. There was an increase in antibody concentration before the booster and 3 months after, from a median of 1.7 U/mL to 9540 U/mL. Every subject showed a statistically significant increment of antibody concentration 3 months after the booster (p < 0.01). Thirty-seven (39.8%) subjects received two doses of the Sinovac vaccine and were confirmed to have COVID-19 with the Delta variant. After the booster, 26 (28%) subjects were infected with the Omicron Variant. Among the subjects who received two doses of the Sinovac vaccine and were confirmed with COVID-19, 36 (30.1%) had mild symptoms, and 1 (1.1%) was asymptomatic. CONCLUSIONS: Heterologous Moderna vaccine booster effectively increases antibody response against SARS-CoV-2 variants and shows mild symptoms of COVID-19 infection.

Clinical characteristics and quality of life of persistent symptoms of COVID-19 syndrome in Indonesia.

Introduction: Coronavirus disease-2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) manifests in a broad clinical spectrum. COVID-19 survivors report various symptoms up to several months after being infected. The purpose of this study was to determine the prevalence of persistent COVID-19 syndrome in Indonesia, the factors that influence the incidence, and the quality of life. Methods: This was a cross-sectional study with an online questionnaire conducted in January 2021. Inclusion criteria were: adult Indonesian citizens who had recovered from COVID-19, and were confirmed negative by RT-PCR of nasal swabs or had undergone an isolation period for a minimum of 14 days. Data analysis was performed by the Chi-square test, followed by multivariate analysis with the backward likelihood ratio method. Results: From a total of 385 respondents, 256 (66.5%) experienced persistent COVID-19 syndrome. The most prevalent symptoms were fatigue (29.4%), cough (15.5%), and muscle pain (11.2%). Of the five aspects of quality of life, the most commonly reported aspects were pain/discomfort and anxiety/depression. The risk of persistent COVID-19 syndrome was significantly higher in subjects with older age, comorbidities, higher clinical severity, previous treatment in hospital, presence of pneumonia, and those who had required oxygen therapy. In the multivariate analysis, the most influential factor for the incidence of persistent COVID-19 syndrome was pneumonia (aOR 2.31, 95% CI 1.29-4.11, p<0.002). Conclusions: The prevalence of the persistent COVID-19 syndrome in Indonesia was high, which affects the quality of life of COVID-19 survivors. Pneumonia was the main factor that influenced the incidence of persistent COVID-19 syndrome. Further research with a larger sample size and a longer study time is recommended to control COVID-19 and its impact on the health and quality of life of COVID-19 survivors.

Lung Fibrosis Sequelae After Recovery from COVID-19 Infection.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus that causes coronavirus diseases 2019 (COVID-19). The SARS-CoV-2 is very contagious and nobody is known to be immune to it. The post-infected lung would leave a scar known as fibrosis, a scar tissue. A study from Wuhan, China suggested the development of fibrosis, though it was too early to label these lung changes as irreversible fibrosis in a time range of 3 weeks. The occurrence of fibrosis indicates a chronic infection which greatly contributes to the hallmark symptom of COVID-19 induced ARDS such as shortness of breath and chest pain. However, many of those studies have not yet explained the condition of the patient's lung after total recovery from the COVID-19. This report demonstrates the clinical symptoms, chest CT scan, spirometry, and blood gas analysis of patient after total recovery from the COVID-19 with appearance lung fibrosis.

A multicentre surveillance study on the characteristics, bacterial aetiologies and in vitro antibiotic susceptibilities in patients with acute exacerbations of chronic bronchitis.

BACKGROUND AND OBJECTIVE: Antimicrobial resistance is a global problem and the prevalence is high in many Asian countries. METHODS: A prospective observational study of the prevalence of bacterial pathogens and their antimicrobial susceptibilities in patients with acute exacerbations of chronic bronchitis (AECB) was conducted in Indonesia, Philippines, Korea, Thailand, Malaysia, Taiwan and Hong Kong from August 2006 to April 2008. The diagnosis of AECB was based on increased cough and worsening of two of following: dyspnoea, increased sputum volume or purulence. Patients who had taken antibiotics within 72 h of presentation were excluded. All bacterial strains were submitted to a central laboratory for re-identification and antimicrobial susceptibility testing to 16 antimicrobial agents according to Clinical and Laboratory Standards Institute. RESULTS: Four hundred and seven isolates were identified among 447 patients of AECB. The most frequent organisms isolated were Klebsiella pneumoniae and associated species (n = 91 + 17), Haemophilus influenzae (n = 71), Pseudomonas aeruginosa (n = 63), Streptococcus pneumoniae (n = 32), Acinetobacter baumannii (n = 22) and Moraxella catarrhalis (n = 21). According to Clinical and Laboratory Standards Institute susceptibility breakpoints, 85.7% and >90% of these pathogens were susceptible to levofloxacin and cefepime respectively. Other options with overall lower susceptibilities include imipenem, ceftazidime, ceftriaxone and amoxicillin/clavulanate. CONCLUSIONS: Gram-negative bacteria including Klebsiella spp., P. aeruginosa and Acinetobacter spp. constitute a large proportion of pathogens identified in patients with AECB in some Asian countries. Surveillance on the local prevalence and antibiotic resistance of these organisms is important in guiding appropriate choice of antimicrobials in the management of AECB.

Clinical course of avian influenza A(H5N1) in patients at the Persahabatan Hospital, Jakarta, Indonesia, 2005-2008.

BACKGROUND: Limited understanding of the presentation and course of influenza A(H5N1) infection in humans hinders evidence-based management. METHODS: We reviewed the case records of patients admitted to the Persahabatan Hospital (RSP), Jakarta, Indonesia, with influenza A(H5N1) confirmed by real-time polymerase chain reaction. RESULTS: Twenty-two previously well patients, aged 3 to 47 years (median 24.5 years), were identified. All attended a clinic or hospital after a median of 2 days of illness (range 0-7). Times to first dose of oseltamivir (three died before receiving oseltamivir) were 2 to 12 days (median 7 days), administered mostly (n = 15) at RSP. Nineteen patients required mechanical ventilation. Deaths numbered 18 (case fatality = 82%) occurring within hours to 6 days of RSP admission, corresponding to 6 to 16 days of illness. Admission hyperglycemia ( >or= 140 mg/dL), unrelated to steroids or known underlying diabetes mellitus, and elevated D-dimer levels (0.81-5.2 mg/L, upper limit of normal < 0.5 mg/L) were present in 14/21 (67%) and 20/21 (95%) patients, respectively. Fibrinogen concentrations were mostly low/normal at 129.9 to 517.9 mg/dL (median 241.1, normal 200-400 mg/dL), whereas C-reactive protein (9/11) and ferritin (6/8) levels were increased. Risk factors for death (univariate analysis) included: (1) increased D-dimers, (2) hyperglycema, (3) increased urea, (4) more extensive chest radiograph shadowing, and (5) lower admission oxygen saturation. CONCLUSIONS: Early diagnosis and effective treatment of human influenza A(H5N1) infection remains challenging. Most patients were referred late with advanced disease. Oseltamivir had limited clinical impact. Elevated D-dimer levels, consistent with fibrinolysis, and hyperglycemia warrant more research to determine their underlying mechanisms and optimal treatment.
