J Glob Antimicrob Resist 2024; 38:363-367. [PMID: 39117143 DOI: 10.1016/j.jgar.2024.07.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2024] [Revised: 07/10/2024] [Accepted: 07/29/2024] [Indexed: 08/10/2024] Open
Abstract
OBJECTIVES The emergence of multidrug-resistant (MDR) Acinetobacter baumannii has become a serious worldwide medical problem. This study was designed to clarify the genetic and epidemiological properties of MDR A. baumannii clinical isolates. METHODS A total of 66 MDR A. baumannii isolates were obtained from 66 inpatients between May 2019 and February 2020 in a university hospital in Nepal. Whole genomes of these isolates were sequenced using next-generation sequencing. Phylogenetic trees were constructed from single nucleotide polymorphism concatemers. Multilocus sequence typing (MLST) and clonal complex (CC) analysis were conducted, and drug-resistance genes were identified. RESULTS Of the 66 isolates, 26 harboured a gene encoding NDM-type metallo-β-lactamase, and 55 harboured a gene encoding the 16S rRNA methyltransferase, ArmA. All isolates had point mutations in the quinolone-resistance-determining regions of gyrA and parC. Phylogenetic analysis showed that 55 isolates harboured armA, 26 harboured blaNDM-1, and14 harboured blaPER-7. Multilocus sequence typing and CC analysis revealed that 34 isolates belonged to CC2 (ST2), 10 to CC1 (nine ST1 and one ST623), and eight to CC149 (ST149). Compared to our previous study on MDR A. baumannii in Nepal in 2012, the isolation rate of CC2 increased, whereas that of CC149 decreased between 2012 and 2020. CONCLUSIONS This study indicates that MDR A. baumannii producing carbapenemase and 16S rRNA methyltransferase, with high resistance to carbapenems and/or aminoglycosides, are spreading in medical settings in Nepal. The genetic backgrounds of MDR A. baumannii isolates have shifted to international clone 2 over several years.

Acute and post-acute respiratory complications of SARS-CoV-2 infection: population-based cohort study in South Korea and Japan. Nat Commun 2024; 15:4499. [PMID: 38802352 PMCID: PMC11130304 DOI: 10.1038/s41467-024-48825-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Accepted: 05/13/2024] [Indexed: 05/29/2024] Open
Abstract
Considering the significant burden of post-acute COVID-19 conditions among patients infected with SARS-CoV-2, we aimed to identify the risk of acute respiratory complications or post-acute respiratory sequelae. A binational population-based cohort study was conducted to analyze the risk of acute respiratory complications or post-acute respiratory sequelae after SARS-CoV-2 infection. We used a Korean nationwide claim-based cohort (K-COV-N; n = 2,312,748; main cohort) and a Japanese claim-based cohort (JMDC; n = 3,115,606; replication cohort) after multi-to-one propensity score matching. Among 2,312,748 Korean participants (mean age, 47.2 years [SD, 15.6]; 1,109,708 [48.0%] female), 17.1% (394,598/2,312,748) were infected with SARS-CoV-2. The risk of acute respiratory complications or post-acute respiratory sequelae is significantly increased in people with SARS-CoV-2 infection compared to the general population (acute respiratory complications: HR, 8.06 [95% CI, 6.92-9.38]; post-acute respiratory sequelae: 1.68 [1.62-1.75]), and the risk increased with increasing COVID-19 severity. We identified COVID-19 vaccination as an attenuating factor, showing a protective association against acute or post-acute respiratory conditions. Furthermore, while the excess post-acute risk diminished with time following SARS-CoV-2 infection, it persisted beyond 6 months post-infection. The replication cohort showed a similar pattern in the association. Our study comprehensively evaluates respiratory complications in post-COVID-19 conditions, considering attenuating factors such as vaccination status, post-infection duration, COVID-19 severity, and specific respiratory conditions.

Predictors and patterns of empirical antibiotic therapy and associated outcomes in COVID-19 patients: a retrospective study in a tertiary care facility in South India. Expert Rev Anti Infect Ther 2024; 22:333-341. [PMID: 38189087 DOI: 10.1080/14787210.2024.2303019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 12/19/2023] [Indexed: 01/09/2024]
Abstract
BACKGROUND The coronavirus disease (COVID-19) led to a global health crisis. Inappropriate use of antibiotics in COVID-19 patients has been a concern, leading to antimicrobial resistance. This study evaluated the patterns and predictors of empirical antibiotic therapy in COVID-19 patients and associated outcomes. METHODS A hospital-based retrospective study was conducted with 525 patients admitted to Kasturba Hospital, Manipal, India, with moderate and severe COVID-19 from 1 March to 1 August 2021. They were divided based on empirical therapy, and predictors of antibiotic usage were assessed by logistic regression. RESULTS Four hundred and eighty (91.4%) COVID-19 patients received at least one course of antibiotics, with 440 (83.8%) initiating empirical therapy. Patients with severe COVID-19 manifestations were more likely to be prescribed empirical antibiotics. Multivariable analysis showed that patients initiated on empirical antibiotics had significantly elevated levels of procalcitonin [OR: 3.91 (95% CI: 1.66-9.16) (p = 0.001)], invasive ventilation [OR: 3.93 (95% CI: 1.70-9.09) (p = 0.001)], shortness of breath [OR: 2.25 (95% CI: 1.30-3.89) (p = 0.003)] and higher CRP levels [OR: 1.01 (95% CI: 1.00-1.01) (p = 0.005)]. Most antibiotics (65.9%) were prescribed from the 'Watch' group, the highest being ceftriaxone. Only 23.8% of the patients had microbiologically confirmed infections. CONCLUSION The study identified predictors for initiating empirical antibacterial therapy in our setting.

Availability of access, watch, and reserve (AWaRe) group of antibiotics in community pharmacies located close to a tertiary care hospital in Lalitpur, Nepal. PLoS One 2023; 18:e0294644. [PMID: 37983218 PMCID: PMC10659150 DOI: 10.1371/journal.pone.0294644] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Accepted: 11/06/2023] [Indexed: 11/22/2023] Open
Abstract
INTRODUCTION The access, watch, and reserve (AWaRe) classification of antibiotics was developed in 2019 by the WHO Expert Committee on the Selection and Use of Essential Medicines as a tool to support antibiotic stewardship efforts at local, national, and global levels. The objectives of this study were to assess the availability of antibiotics as per WHO AWaRe classification at community pharmacies located around a tertiary care hospital in Lalitpur and to compare these antibiotics with the national essential medicine list of Nepal. METHOD The cross-sectional study was conducted at community pharmacies located within a two-kilometer radius of a teaching hospital from August to November 2022. A total of 82 community pharmacies registered with the Nepal Chemist and Druggists Association and the Department of Drug Administration were studied. Data was collected using a standard proforma containing the names of the antibiotics classified as per the WHO's AWaRe classification. RESULTS Access group of antibiotics, Ampicillin, (82;100%), Amoxycillin, (82;100%), Flucloxacillin, (82;100%), and Metronidazole, (82;100%) were available in all community pharmacies. Results from the watch group showed that Azithromycin, (80; 97.6%) was available in all pharmacies followed by Cefixime, (80; 97.6%), Ciprofloxacin, (73; 89%), Levofloxacin, (74; 90.2%)and Ofloxacin, (74; 90.2%). Linezolid, (24; 29.3%) was the most common antibiotics available from the reserve group of antibiotics. Colistin was the second commonly available antibiotic. The most available antibiotic from the not recommended group were Ampicillin/Cloxacillin (82; 100%), followed by Piperacillin/Sulbactam, (39; 47.6%). There were differences in the classification of antibiotics between the WHO AWaRe list and the Essential Medicines list of Nepal in terms of numbers of antibiotics listed. CONCLUSION Antibiotics from the not recommended and reserve groups were commonly available in community pharmacies. The implementation of antibiotic guidelines should be emphasized along with strict monitoring of the sale of antibiotics without a prescription in community pharmacy settings.

Use of antimicrobials during the COVID-19 pandemic: A qualitative study among stakeholders in Nepal. PLOS GLOBAL PUBLIC HEALTH 2023; 3:e0002166. [PMID: 37963156 PMCID: PMC10645294 DOI: 10.1371/journal.pgph.0002166] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Accepted: 10/05/2023] [Indexed: 11/16/2023]
Abstract
The COVID-19 pandemic was a major public health threat and the pressure to find curative therapies was tremendous. Particularly in the early critical phase of the pandemic, a lot of empirical treatments, including antimicrobials, were recommended. Drawing on interviews with patients, clinicians and drug dispensers, this article explores the use of antimicrobials for the management of COVID-19 in Nepal. A total of 30 stakeholders (10 clinicians, 10 dispensers and 10 COVID-19 patients) were identified purposively and were approached for an interview. Clinicians and dispensers in three tertiary hospitals in Kathmandu assisted in the recruitment of COVID-19 patients who were undergoing follow-up at an out-patient department. Interviews were audio recorded, translated and transcribed into English, and were analyzed thematically. The respondents report that over-the-counter (OTC) use of antibiotics was widespread during the COVID-19 pandemic in Nepal. This was mostly rooted in patients' attempts to mitigate the potential severity of respiratory illnesses, and the fear of the stigmatization and social isolation linked to being identified as a COVID-19 patient. Patients who visited drug shops and physicians reportedly requested specific medicines including antibiotics. Clinicians reported uncertainty when treating COVID-19 cases that added pressure to prescribe antimicrobials. Respondents from all stakeholder groups recognized the dangers of excessive use of antimicrobials, with some referring to the development of resistance. The COVID-19 pandemic added pressure to prescribe, dispense and overuse antimicrobials, accentuating the pre-existing OTC use of antimicrobials. Infectious disease outbreaks and epidemics warrant special caution regarding the use of antimicrobials and specific policy response.

Abstract
BACKGROUND During the initial stages of the coronavirus disease 2019 (COVID-19) pandemic, the administration of antibiotics to patients was prevalent in numerous countries. Despite this, the rising threat of antimicrobial resistance (AMR) presents a significant public health concern. The escalation of AMR has been exacerbated by the ongoing COVID-19 pandemic. Against this backdrop, the primary aim of this study was to conduct a bibliometric and visual analysis of research pertaining to the use of antibiotics in COVID-19. METHODS This study examined documents indexed in Scopus between 2020 and 2022. To visualize the trends and hotspots of research related to antibiotics and COVID-19, as well as collaborative networks, the researcher utilized version 1.6.18 of the VOSviewer software. Scopus data were analysed to extract information on the types of publications, annual research output, countries, institutions, funding agencies, journals, citations, and highly cited references. Microsoft Excel 2019 was used to process and organize the extracted data. RESULTS This study analysed 1137 documents related to COVID-19 and antibiotics and found that the number of publications increased from 130 in 2020 to 527 in 2022. These publications included 777 (68.34%) articles and 205 (18.03%) reviews. The top five countries in terms of scientific production were the United States (n = 231; 20.32%), the United Kingdom (n = 156; 13.72%), China (n = 101; 8.88%), India (n = 100; 8.8%), and Italy (n = 63; 5.54%), and the leading institutions were Imperial College London (n = 21; 1.85%), University of Oxford (n = 20; 1.76%), and University College London (n = 15; 1.32%). The National Natural Science Foundation of China provided funding for the highest number of articles (n = 48; 4.22%), followed by the National Institutes of Health (n = 32; 2.81%). The most productive journals were Antibiotics (n = 90; 7.92%), Journal of Antimicrobial Chemotherapy (n = 30; 2.64%), and Infection Control and Hospital Epidemiology (n = 26; 2.29%). Finally, the research hotspots identified in this study were 'antimicrobial stewardship during the COVID-19 outbreak' and 'implications of the COVID-19 pandemic on the emergence of antimicrobial resistance.' CONCLUSIONS This is the first bibliometric analysis of COVID-19-related research on antibiotics. Research was carried out in response to global requests to increase the fight against AMR and awareness of the issue. More restrictions on the use of antibiotics are urgently needed from policy makers and authorities, more so than in the current situation.
