Global Pandemic

Community-acquired pneumonia is an acute infection of lung parenchyma which causes local and systemic inflammatory changes via cytokines. Several bacteria and viruses are responsible for this type of pneumonia, and the most common bacterial cause is Streptococcus pneumoniae. The classic symptoms are cough, fever, and pleuritic chest pain. In the Winter of 2020, a new strain of coronavirus known as SARS-CoV-2 spread throughout the world and was responsible for a global pandemic that transformed the way we live our lives. A 93-year old female presented to the hospital with respiratory distress and was found to have not only COVID-19 pneumonia but also superimposed Methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa pneumonia. Following the most up-to-date guidelines, she was determined to have community-acquired pneumonia. Methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa are uncommon causes of communityacquired pneumonia. She was treated with the standard of care at the time, which included vancomycin, piperacillin-tazobactam, and hydroxychloroquine. This case highlights the rarity of this specific presentation of community acquired pneumonia in regards to microbial etiology. It showcases that patients may develop certain diseases despite not having any risk factors. A major takeaway point is that apt decision making is a critical and time sensitive matter when determining whether a bacterial co-infection is present since it can affect patient outcomes. Since co-infections are relatively infrequent, antibiotic use in COVID-19 positive patients needs to be tailored accordingly. At the same time, it is crucial to keep in mind that co-infections are associated with increased severity of COVID-19 as well as poorer outcomes.

BACKGROUND: The high infection of methicillin-resistant Staphylococcus aureus (MRSA) accompanied by increased resistance to many groups of antibiotics is a major concern in the field of infection. This study aims to evaluate the prevalence of MRSA isolates and antimicrobial susceptibility to MRSA isolates in Indonesia. METHODS: We did searches in Pubmed, Proquest, DOAJ, GARUDA, and google scholar for studies published in 2006-2020. Study in Indonesian (Bahasa) and English with the keywords "methicillin-resistant Staphylococcus aureus", "MRSA" and "Indonesia". More than 30 S.aureus isolates derived from human samples were included. RESULTS: A total of 738 articles based on the search results, 13 studies were included in this systematic review. The prevalence of MRSA reported from all studies is 0.3%-52%. The study with the largest prevalence of MRSA was found in Jakarta. The susceptibility of vancomycin antibiotics to MRSA isolates is known to range from 87%-100%. Based on all studies, Linezolid, Tigecycline, Nitrofurantoin, and quinupristin/dalfopristin were reported to have 100% susceptibility. CONCLUSIONS: The prevalence of MRSA is still found high in one of the cities in Indonesia. Surveillance of antibiotic use, monitoring of antimicrobial susceptibility patterns, and antibiotic resistance control programs need to be optimized. MRSA screening is based on a rapid diagnosis when an inpatient admission is also necessary.

Abstract Objective To evaluate nasal carriage, antibiotic susceptibility and molecular characteristics of methicillin-resistant Staphylococcus aureus (MRSA), as well as the risk factors of MRSA colonization, in human immunodeficiency virus (HIV)-infected patients in northern Taiwan. Methods From September 2014 to November 2015, HIV-infected patients seeking outpatient care at four hospitals were eligible for this study. A nasal specimen was obtained from each subject for the detection of S. aureus and a questionnaire was completed by each subject. MRSA isolates once identified were characterized. Results Of 553 patients surveyed, methicillin-susceptible S. aureus (MSSA) was detected in 119 subjects (21.5%) and MRSA in 19 subjects (3.4%). Female gender, injection drug use, smoking, hepatitis C virus carrier, cancer and antibiotic use within one year were positively associated with MRSA colonization. By multivariate analysis, only cancer (adjust odds ratio (aOR) 7.78, [95% confidence interval (CI), 1.909-31.731]) and antibiotic use within one year (aOR 3.89, [95% CI, 1.219-12.433]) were significantly associated with MRSA colonization. Ten isolates were characterized as sequence type (ST) 59/staphylococcal chromosome cassette (SCC) IV or V T , endemic community strains in Taiwan, four isolates as ST 8/SCC mec IV (USA 300) and one isolate as ST 239/SCC mec IIIA, a hospital strain. All the community-associated MRSA isolates were susceptible to trimethoprim-sulfamethoxazole (TMP-SMX). Conclusions Nasal MRSA carriage in HIV-infected patients seeking outpatient care was low (3.4%) in northern Taiwan. Most of the colonizing isolates were genetically endemic community strains and exhibited high susceptibility to TMP-SMX and fluoroqinolones. Cancer and antibiotic use within one year were associated with MRSA colonization.

ABSTRACT We performed secondary analyses of a postdischarge decolonization trial of MRSA carriers that reduced MRSA infection and hospitalization by 30%. Hospitalized MRSA infection was associated with 7.9 days of non-MRSA antibiotics and CDI in 3.9%. Preventing MRSA infection and associated hospitalization may reduce antibiotic use and CDI incidence.

Methicillin-resistant Staphylococcus aureus (MRSA) causes purulent skin and soft tissue infections as well as other life-threatening diseases. Recent guidelines recommend screening for MRSA at the time of admission. However, few studies have been conducted to determine the prevalence and risk factors for MRSA colonization. A prospective data collection and retrospective analysis was performed. MRSA screening tests were performed using nasal swabs in patients enrolled between January 2017 and July 2018. Demographic data, socio-economic data, medical comorbidities, and other risk factors for MRSA carriage were evaluated among 1577 patients enrolled in the study. The prevalence of MRSA nasal carriage was 7.2%. Univariate regression analysis showed that colonization with MRSA at the time of hospital admission was significantly related to patient age, body mass index, smoking, alcohol, trauma, recent antibiotic use, and route of hospital admission. Multiple logistic regression analysis for the risk factors for positive MRSA nasal carriage showed that being under- or overweight, trauma diagnosis, antibiotic use one month prior to admission, and admission through an emergency department were related to MRSA colonization. This study highlights the importance of a preoperative screening test for patients scheduled to undergo surgery involving implant insertion, particularly those at risk for MRSA.
