Antimicrobial resistance and over the counter use of drugs in Nepal

A Decade-Long Analysis of Trends in Antimicrobial Resistance in a Neurosurgical Hospital in Kathmandu, Nepal

Multidrug-resistant (MDR) bacteria cause infections with higher risks of morbidity, mortality, and financial burden. Understanding the antimicrobial resistance patterns of these pathogens is crucial for effective treatment and managing resistance. Therefore, this retrospective study examined the prevalence, causes, and trends in antimicrobial resistance in bacterial infections at a neurosurgical hospital in Nepal. We analyzed the demographics, bacteriological profiles, and antimicrobial susceptibility results in patients who visited Dirghayu Guru Hospital and Research Center, Kathmandu, Nepal, between January 2014 and January 2024, using SPSS, version 17.00. Among 4758 patients, 465 (9.77%) had infections caused by 571 bacteria. Of them, 435 (93.55%) patients had urinary tract infections, 89 (19.14%) had bloodstream infections, and 31 (6.67%) had respiratory tract infections. Klebsiella pneumoniae (n = 172, 30.12%) was the predominant bacteria. Proportions of drug-resistant Enterobacterales and gram-positive cocci among drug-resistant bacteria against tetracyclines were 83.33% and 45.83%, cephalosporins were 78.02% and 40.45%, quinolones were 72.25% and 50.00%, aminoglycosides were 65.14% and 43.53%, carbapenems were 62.96% and 30.00%, penicillins were 54.55% and 57.89%, and penicillin with beta-lactamase inhibitors (PwBLIs) were 40.54% and 42.31%, respectively. Proportions of drug-resistant nonfermenters among drug-resistant bacteria showed 100.00% resistance to these antimicrobials. MDR isolates (n = 118, 20.67%) were 100.00% susceptible to piperacillin-tazobactam and 83.33% to polymyxin B. Over the years, resistance increased for cephalosporins (48.15%-60.53%) but decreased for carbapenems (50.00%-33.33%), penicillins (64.29%-42.31%), PwBLIs (50.00%-12.50%), aminoglycosides (60.00%-49.12%), tetracyclines (100.00%-16.67%), and polymyxins (76.22%-16.67%). One-tenth of hospital-visiting patients had bacterial infections, with three-fourths involving Enterobacterales and one-fifth involving MDR bacteria. In recent years, resistance to cephalosporins has increased, whereas resistance to other beta-lactams, aminoglycosides, and polymyxins has decreased.

Antibiotic prescription patterns in the emergency department of a tertiary healthcare center in Nepal: a descriptive cross-sectional study

OBJECTIVE

To describe antibiotic prescription patterns in the emergency department (ED) of a tertiary healthcare center in Nepal.

METHODS

This was a descriptive cross-sectional study of hospital records of patients who visited the ED.

RESULTS

Of the 758 ED patients included in the study, 384 (50.6%) received a total of 536 antibiotic prescriptions. Common indications for antibiotic prescriptions included respiratory infection (37.5%), gastrointestinal infection (19.3%), urinary infection (10.4%), and prophylaxis (29.9%). Antibiotics listed as essential in the National List of Essential Medicines (NLEM) and generic formulations were used in 77.1% and 61.9% of the antibiotic prescriptions, respectively. Injectable antibiotics were prescribed to 54.9% of the 384 patients. Frequently prescribed antibiotics included ceftriaxone (34.1%), metronidazole (18.5%), amoxicillin + clavulanic acid (15.9%), and cefixime (14.3%). Bacterial culture testing was performed in 15.1% of the patients who received antibiotics.

CONCLUSIONS

This study showed that overuse of antibiotics, prescription of branded antibiotics, prescription of antibiotics not listed in the NLEM, prophylactic use of antibiotics, and empirical treatment of suspected infections without isolation of pathogens were all prevalent. We recommend more research to determine the causes underlying these practices and develop interventions to limit such practices.

Emergence of mcr-1 Gene in Colistin-Resistant Escherichia coli Isolates from Chicken in Chitwan, Nepal

The escalating prevalence of colistin-resistant Escherichia coli in poultry has emerged as a significant concern. This study aimed to assess the occurrence of the mcr-1 gene in colistin-resistant E. coli isolates from poultry samples. A cross-sectional study was conducted at National Avian Disease Investigation Laboratory, Nepal, on 210 chicken meat samples, including liver, heart, and spleen. E. coli was isolated and identified by conventional cultural methods. Antibiotic resistance pattern was assessed by the Kirby-Bauer disc diffusion method. The mcr-1 gene was detected by conventional polymerase chain reaction. The average viable count in chicken meat samples was log 6.01 CFU (colony-forming unit)/g, whereas the average coliform count was log 3.85 CFU/g. Coliforms were detected in at least one sample from 48.01% of total samples. The prevalence of E. coli in all meat samples was 39.52%. Liver accounted for the largest fraction of E. coli isolates (45.45%). Cefepime was the most effective antibiotic. Among all isolates, 45 (54.21%) were multidrug-resistant E. coli, 17 (20.48%) were colistin-resistant E. coli, and 11 (64.70%) harbored the mcr-1 gene. High prevalence of multidrug-resistant E. coli isolates, colistin-resistant isolates, and mcr-1 gene-carrying isolates indicates a serious concern, as it could potentially lead to colistin resistance in human pathogens through horizontal transfer of resistant genes from poultry to humans.

Point Prevalence Survey of Antimicrobial Prescription and Consumption in a Nigerian Tertiary Hospital: A Gateway to the Antimicrobial Stewardship Program

BACKGROUND

Antimicrobial stewardship is an important action plan for curbing the rising trend of antimicrobial resistance (AMR). Surveillance of antimicrobial use and consumption is needed as baseline data and for monitoring the impact of antimicrobial stewardship interventions. The survey was done to understand the burden of AMR, in view of establishing an antimicrobial stewardship program in our hospital.

METHODS

A point prevalence survey (PPS) of antimicrobial use and consumption was conducted on all inpatients admitted before 8.00 am on the days of the survey using a standardized questionnaire. The collected data were entered online into the Global PPS web-based application (www.global-pps.com), for analysis.

RESULT

Of the 178 patients admitted during the survey period, 50.6% were on one or more antimicrobial agents. All the patients in adult intensive care units were on antibiotics (100%), followed by neonatal intensive care units (83.3%), with the least being adult medical wards (39.4%). Beta-lactam antibiotics were the most frequently prescribed antimicrobial for various infections, especially skin and soft tissue infections, 41.3%, which were the most common diagnoses treated with antibiotics. The infection was mostly community-acquired (81.6%), of which 94.9% were treated empirically. There was no written guideline in existence.

CONCLUSION

The present study revealed a poor prescribing habit because of a high rate of empirical treatment. The need for antimicrobial stewardship cannot be overemphasized as it will help streamline and improve the prescribing pattern.

Drivers of antimicrobial resistance within the communities of Nepal from One Health perspective: a scoping review

Background

A major driver of antimicrobial resistance (AMR) is the inappropriate use of antimicrobials. At the community level, people are often engaged in behaviors that drive AMR within human, animal, and environmental (One Health) impacts. This scoping review consolidates research to determine (a) the community's knowledge, attitudes, and practices around AMR; (b) existing community-based interventions; and (c) barriers and enablers to addressing AMR in Nepal.

Methods

This scoping review follows the Joanna Briggs Institute scoping review methodology. Literature indexed in PubMed, Scopus, CINAHL, Global Index Medicus, HINARI-SUMMON, Embase (Ovid), Global Health (Ovid), CAB Abstracts (Ovid), Web of Science, and Google Scholar between January 2000 and January 2023 were reviewed for inclusion. Articles were included in the review if they considered the issues of AMR at the community level in Nepal; this excluded clinical and laboratory-based studies. A total of 47 studies met these criteria, were extracted, and analyzed to consolidate the key themes.

Results

A total of 31 (66%) articles exclusively included human health; five (11%) concentrated only on animal health; no studies solely focused on environmental aspects of AMR; and the remaining studies jointly presented human, animal, and environmental aspects. Findings revealed inadequate knowledge accompanied by inappropriate practice in both the human and animal health sectors. Four community interventions improved knowledge and practices on the appropriate use of antimicrobials among community people. However, various social and economic factors were found as barriers to the appropriate use of antimicrobials in the community.

Conclusion

Community engagement and One Health approaches could be key tools to improve awareness of AMR and promote behavioral change related to AM use in communities, as current studies have revealed inadequate knowledge alongside inappropriate practices shared in both human and animal health sectors.

Exploring knowledge, perceptions, and practices of antimicrobials, and their resistance among medicine dispensers and community members in Kavrepalanchok District of Nepal

BACKGROUND

Inappropriate use of antimicrobials is a global public health issue, particularly in developing countries, including Nepal, where over-the-counter sales and self-medication of antimicrobials are common.

OBJECTIVES

To explore knowledge, perceptions, and practices of antimicrobials and their resistance among medicine dispensers and community members in Nepal.

METHODS

The study was conducted in three rural and five urban municipalities of the Kavrepalanchok district from May 2021 to August 2021. Data were collected using two qualitative approaches: In-Depth Interviews (IDIs) and Focus Group Discussions (FGDs). Data were analyzed using thematic analysis that combined deductive and inductive approaches to identify codes under pre-specified themes.

RESULTS

A total of 16 In-depth interviews with medicine dispensers and 3 focus group discussions with community members were conducted. Knowledge regarding antimicrobial resistance varied among dispensers. Those with a prior educational background in pharmacy often had good knowledge about the causes and consequences of antimicrobial resistance. Meanwhile, consumers were less aware of antimicrobial resistance. Community members perceived antimicrobials as effective medicines but not long-term solution for treating diseases. They reported that dispensing without a prescription was common and that both consumers and dispensers were responsible for the inappropriate use of antimicrobials. On the contrary, several dispensers said that self-medication was common among the consumers, especially among more educated groups. The medicine dispensers and consumers expressed concerns about the weak enforcement of policies regarding pharmacy drug use and dispensing practices.

CONCLUSION

Promoting and strengthening the appropriate use of antimicrobials among medicine dispensers and community members is crucial. Bold policies and collective implementation of regulations could help combat antimicrobial resistance.

Exploring community insights on antimicrobial resistance in Nepal: a formative qualitative study

BACKGROUND

Antimicrobial resistance (AMR) is the process by which microbes evolve mechanisms to survive the medicines designed to destroy them i.e. antimicrobials (AMs). Despite being a natural process, AMR is being hastened by the abuse of AMs. In context of Nepal, there is limited information on drivers of AMR and barriers in addressing it from a community perspective. This study explores the local language and terminology used around AMs in the community, commonly used AMs and reasons for their usage, how these AMs are sourced, and the perceived barriers to addressing AMR via One Health approach.

METHODS

A phenomenological study design was utilized with applied qualitative research theoretically framed as pragmatism. Twelve in-depth interviews and informal discussions with a One Health focus, were purposively conducted with wide range of stakeholders and community resident of Kapilvastu municipality of Nepal during April 2022. The acquired data was analyzed manually via a thematic framework approach. The study obtained ethical approval from ethical review board of Nepal Health Research Council and University of Leeds.

RESULTS

Nepali and Awadhi languages does not have specific words for AMs or AMR, which is understandable by the community people. Rather, community use full explanatory sentences. People use AMs but have incomplete knowledge about them and they have their own local words for these medicines. The knowledge and usage of AMs across human and animal health is impacted by socio-structural factors, limited Government regulation, inadequate supply of AMs in local government health facilities and the presence of various unregulated health providers that co-exist within the health system. Novel ideas such as the use of visual and smart technology, for instance mobile phones and social media exposure, can enable access to information about AMs and AMR.

CONCLUSION

This study shows that terminology that is understandable by the community referring to AMs and AMR in Nepali and Awadhi languages does not exist, but full explanatory sentences and colloquial names are used. Despite regular utilisation, communities have incomplete knowledge regarding AMs. Since, knowledge alone cannot improve behaviour, behavioural interventions are required to address AMR via community engagement to co-produce their own solutions.

Clinical utility of procalcitonin in implementation of procalcitonin-guided antibiotic stewardship in the South-East Asia and India: evidence and consensus-based recommendations

INTRODUCTION

The South-East Asian (SEA) region and India are highly susceptible to antibiotic resistance, which is caused due to lack of antimicrobial stewardship (AMS) knowledge, uncontrolled use of antibiotics, and poor infection control. Nonadherence to national/local guidelines, developed to combat antimicrobial resistance, is a major concern. A virtual advisory board was conducted to understand the current AMS standards and challenges in its implementation in these regions.

AREAS COVERED

Procalcitonin (PCT)-guided antibiotic use was discussed in various clinical conditions across initiation, management, and discontinuation stages. Most experts strongly recommended using PCT-driven antibiotic therapy among patients with lower respiratory tract infections, sepsis, and COVID-19. However, additional research is required to understand the optimal use of PCT in patients with organ transplantation and cancer patients with febrile neutropenia. Implementation of the solutions discussed in this review can help improve PCT utilization in guiding AMS in these regions and reducing challenges.

EXPERT OPINION

Experts strongly support the inclusion of PCT in AMS. They believe that PCT in combination with other clinical data to guide antibiotic therapy may result in more personalized and precise targeted antibiotic treatment. The future of PCT in antibiotic treatment is promising and may result in effective utilization of this biomarker.

Extended-spectrum β-lactamases producing Enterobacteriaceae (ESBL-PE) prevalence in Nepal: A systematic review and meta-analysis

An alarming increase in the occurrence of extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-PE) has threatened the treatment and management of bacterial infections. This systematic review and meta-analysis aimed to provide a quantitative estimate of the prevalence of ESBL among the members of the Enterobacteriaceae family by analyzing the community-based and clinical studies published between 2011 and 2021 from Nepal and determine if ESBL-PE correlates with multidrug resistance (MDR). The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed for systematic review and meta-analysis and the articles' quality was assessed using the Newcastle-Ottawa scale. Of the 2529 articles screened, 65 articles were systematically reviewed, data extracted, and included in in-depth meta-analysis. The overall pooled prevalence of ESBL-producers in Enterobacteriaceae was 29 % (95 % CI: 26-32 %) with high heterogeneity (I2 = 96 %, p < 0.001). Escherichia coli was the predominant ESBL-producing member of the Enterobacteriaceae family, followed by Citrobacter spp. and Klebsiella spp. The prevalence of ESBL-PE increased from 18.7 % in 2011 to 29.5 % in 2021. A strong positive correlation (r = 0.98) was observed between ESBL production and MDR in Enterobacteriaceae. ESBL-PE isolates showed high resistance to ampicillin, cephalosporins, and amoxicillin-clavulanic acid, and blaCTX-M type was the most reported gene variant among ESBL-PE. In conclusion, this study demonstrated an increased prevalence of ESBL-PE in Nepal over the last decade, and such isolates showed a high level of MDR against the β-lactams and non-β-lactam antibiotics. Tackling the rising antibiotic resistance (AR) and MDR in ESBL-PE would require concerted efforts from all stakeholders to institute effective infection control programs in the community and clinical settings.

Use of antimicrobials during the COVID-19 pandemic: A qualitative study among stakeholders in Nepal

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.

Exploring the potential for children to act on antimicrobial resistance in Nepal: Valuable insights from secondary analysis of qualitative data

This study explores the perceived roles of children in antimicrobial resistance (AMR) in two sites across Nepal. AMR is a global challenge and underpinned by many complex behavioural drivers including how antimicrobial medicines are sourced and used. Because of this social dynamic, several research groups are using community engagement (CE) approaches to understand AMR at community level. However, most data negate the importance of children in behaviours linked to, and potentially driving AMR. In this study, authors apply secondary analysis methods to 10 transcripts representing the views of 23 adults engaged in an AMR-focused film-making project. By focusing on participants' reference to children, we reveal that antimicrobial usage and adherence to health providers' messages can be influenced by the age of the patient. Secondly that children are involved in some of the behaviours which are known to drive antimicrobial resistance such as purchasing over-the-counter antibiotic drugs. Finally, community members discuss that, with careful creation of resources, AMR could be meaningfully presented in educational settings with a view to children acting as agents of change around AMR-driving behaviours. Findings suggest that age-inclusive community engagement projects could be effective in tackling AMR at community level in Nepal and other low resource settings.

Urogenital pathogens in urine samples of clinically diagnosed urinary tract infected patients in Tanzania: A laboratory based cross-sectional study

Background

Urogenital pathogens such as Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium and Trichomonas vaginalis have been reported to cause pyuria, however they are not routinely cultured from urine samples of patients clinically diagnosed to have urinary tract infections (UTI). In this study, pathogen specific PCR was done to identify the urogenital pathogens in the urine samples among clinically diagnosed UTI patients with negative routine urine culture.

Methods

A cross-sectional study was conducted involving 227 archived urine samples from clinically diagnosed UTI patients with positive leucocyte esterase but negative urine culture results. The urogenital pathogens were detected using pathogen specific singleplex PCR. Data were cleaned and analyzed using STATA version 15.

Results

The median age of patients was 31[IQR 23 - 51] years and the majority (174, 76.7%) were females. Two thirds of patients had history of antibiotic use two weeks prior to recruitment (154, 67.8%). A total of 62(27.3%) urine samples were positive for at least one urogenital pathogen. Of 62 positive samples, 9 had two urogenital pathogens and 1 had three urogenital pathogens. The most predominant urogenital pathogen detected was Neisseria gonorrhoeae 25(34.2%) and Trichomonas vaginalis 24(32.9%). Being female (aOR 2.4; 95% CI: 1.04 - 5.49; p-value 0.039) and having history of using antibiotics in the past two weeks (aOR 1.9; 95%CI: 1.04 - 3.60; p-value 0.036) was independently associated with the presence of urogenital pathogens.

Conclusion

More than a quarter of female patients with clinical symptoms of UTI and routine urine culture negative results were infected with urogenital pathogens mainly Neisseria gonorrhoeae and Trichomonas vaginalis. Further research with a larger sample set in a range of settings is required to understand the implications of these finding generally.

Antibiotics Prescription, Dispensing Practices and Antibiotic Resistance Pattern in Common Pathogens in Nepal: A Narrative Review

Antimicrobial resistance (AMR) is increasing and it is a serious public health problem worldwide. Nepal is considered as one of the contributors for rising AMR due to the most prevalent irrational use of antibiotics. In this review, we have assessed the practices of antibiotic prescription and dispensing, and antibiotic resistance of commonly encountered bacteria in Nepal. There is exponential increase of therapeutic consumption of antibiotics either without clinician's prescription or irrational prescription. Almost half of the population in Nepal was found to purchase antibiotics easily from the nearby pharmacies without clinician's prescription. Irrational prescription is exceeded in remote areas which could be due to lack of access with health posts and hospitals. The third generation cephalosporins, which are considered as the last resort antibiotics were found to be relatively prescribed and dispensed higher as compared to other classes of antibiotics. Despite the existing limited functional surveillance system, antibiotic resistance among bacteria is increasing in Nepal because of irrational prescription, dispensing and consumption of antibiotics without prescription.

Antimicrobial resistance in bacteria isolated from the poultry production system in Nepal

SETTING

Twenty poultry farms in five provinces of Nepal were selected for studying bacterial pathogens and their antimicrobial resistance (AMR) patterns.

OBJECTIVE

To document the proportion of cloacal swabs collected from 3,230 broiler and 3,230 layer chickens from September to December 2021 that grew isolates of Escherichia coli, Enterococcus spp. and Salmonella spp. along with their AMR patterns.

DESIGN

This was a cross-sectional descriptive study.

RESULTS

In broiler birds, Enterococcus spp., Salmonella spp. and E. coli were identified in respectively 36%, 39% and 63% of swabs. In layer birds, Enterococcus spp., Salmonella spp. and E. coli were identified in respectively 31%, 48% and 60% of swabs. For both bird types, there was variation in bacterial prevalence between the regions. For all three bacterial isolates, the lowest antimicrobial resistance was found with amikacin. For the other nine antibiotics tested, >50% of bacterial isolates showed resistance; between 60% and 90% of isolates showed resistance to ciprofloxacin and trimethoprim-sulfamethoxazole. Multidrug resistance ranged from 45% to 46% for Salmonella spp., 37-44% for E. coli and 13-17% for Enterococcus spp.

CONCLUSION

This study shows that a large proportion of poultry in Nepal are infected with potentially pathogenic bacteria, and these are frequently resistant to commonly used antibiotics. Nepal urgently needs to implement corrective measures.

One Health approaches adapted in low resource settings to address antimicrobial resistance

Inter-disciplinary collaborations are now considered as key factors for integrated health system strengthening. Its application in the domain of One Health needs more milestones to achieve. Other than the human health sector, the antimicrobials are used in food animals and aquaculture for therapy, prophylaxis and growth promotion which significantly contributes to the development of antimicrobial resistance. It is the high time to develop a sustainable collaboration between the concerned sectors of One Health for a resilient health system. The domain of One Health not only mitigates the emergence of antimicrobial resistance but also helps in realizing the surveillance and epidemiology of zoonotic diseases, and the control of public health emergencies such as COVID-19. The review identified the key One Health strategies adapted by India, the exemplary low resource settings, to address antimicrobial resistance and zoonosis.

Detection of NDM Variants (bla NDM-1, bla NDM-2, bla NDM-3) from Carbapenem-Resistant Escherichia coli and Klebsiella pneumoniae: First Report from Nepal

Background

Increasing burden of carbapenem resistance among Enterobacterales is attributable to their ability to produce carbapenemase enzymes like metallo-beta-lactamase (MBL), Klebsiella pneumoniae carbapenemase (KPC), and OXA-type. This study aimed to determine the prevalence of carbapenemases and MBL genes ((bla_NDM-1,bla_NDM-1 and bla_NDM-3) among E. coli and K. pneumoniae isolates.

Methods

A total of 2474 urine samples collected during the study period (July–December 2017) were processed at the microbiology laboratory of Kathmandu Model Hospital, Kathmandu. Isolates of E. coli and K. pneumoniae were processed for antimicrobial susceptibility testing (AST) by disc diffusion method. Carbapenem-resistant isolates were subjected to Modified Hodge Test (MHT) for phenotypic confirmation, and inhibitor-based combined disc tests for the differentiation of carbapenemase (MBL and KPC). MBL-producing isolates were screened for NDM genes by polymerase chain reaction (PCR).

Results

Of the total urine samples processed, 19.5% (483/2474) showed the bacterial growth. E. coli (72.6%; 351/483) was the predominant isolate followed by K. pneumoniae (12.6%; 61/483). In AST, 4.4% (18/412) isolates of E. coli (15/351) and K. pneumonia (3/61) showed resistance towards carbapenems, while 1.7% (7/412) of the isolates was confirmed as carbapenem-resistant in MHT. In this study, all (3/3) the isolates of K. pneumoniae were KPC-producers, whereas 66.7% (10/15), 20% (3/15) and 13.3% (2/15) of the E. coli isolates were MBL, KPC and MBL/KPC (both)-producers, respectively. In PCR assay, 80% (8/10), 90% (9/10) and 100% (10/10) of the isolates were positive for bla_NDM-1, bla_NDM-2 and bla_NDM-3, respectively.

Conclusion

Presence of NDM genes among carbapenemase-producing isolates is indicative of potential spread of drug-resistant variants. This study recommends the implementation of molecular diagnostic facilities in clinical settings for proper infection control, which can optimize the treatment therapies, and curb the emergence and spread of drug-resistant pathogens.

"AMR Dialogues": a public engagement initiative to shape policies and solutions on antimicrobial resistance (AMR) in Thailand

Background: The use of antimicrobials in Thailand has been reported as one of the highest in the world in both the human and animal sectors. The objectives of this project are: (1) to improve understanding of the issue of antimicrobial resistance (AMR) among adult Thai communities and (2) to drive change through the national AMR policy to include context-specific and locally-driven solutions. Methods: The project contains two components conducted in parallel: the "AMR Dialogues" public engagement project and the embedded evaluation of the project. We will bring together AMR stakeholders and members of the public through a series of conversation events to co-create an AMR stakeholder map, engagement strategy, and context-specific solutions to reduce the burden of AMR. There will be a combination of regional in-person events ('regional conversations') and national online events ('national conversations') with members of the public and AMR stakeholders. The conversations will follow this sequence: introduce and explore issues related to AMR, brainstorm solutions and finally propose promising/feasible solutions to take forward. Evaluation of the project will be conducted to assess if the AMR Dialogues objectives have been achieved using feedback forms and qualitative methods. Ethics: Approval of the evaluation component of the project has been obtained from the ethics committee of the Thailand Institute for the Development of Human Subject Protection (IHRP2021059) and the Oxford University Tropical Research Ethics Committee (OxTREC 529-21). Dissemination: The results of these conversation events will inform the next Thailand National Strategic Plan on AMR. The learning and outcomes will be disseminated to AMR policy makers, academic audiences, and participants of all the conversation events.

Prevalence of methicillin-resistant Staphylococcus aureus in a tertiary hospital in Nepal

SETTING:

Patan Hospital, Lalitpur, Nepal.

OBJECTIVES:

To describe 1) the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and its antibiotic sensitivity pattern; 2) the demographic and clinical characteristics associated with MRSA infections; and 3) the treatment outcomes of in-patients with MRSA infection among patients with S. aureus infection between January 2018 and December 2020.

DESIGN:

This was a cross-sectional study using electronic and paper-based hospital records of patients with S. aureus infection.

RESULTS:

Of the 1,804 patients with S. aureus infection, 1,027 patients (57%, 95% CI 55–59) had MRSA. The MRSA were susceptible to vancomycin (100%), linezolid (96%), doxycycline (96%), chloramphenicol (86%) and cotrimoxazole (70%), and resistant to erythromycin (68%), clindamycin (56%), gentamycin (58%), ciprofloxacin (92%) and ofloxacin (91%). The prevalence of MRSA was higher in 2019, among out-patients, and in respiratory samples, and lower in blood samples. Of the 142 in-patients with MRSA, 93% had a successful clinical outcome (cured/improved).

CONCLUSION:

More than 50% of patients with S. aureus infection had MRSA that were resistant to commonly available antibiotics. This calls for strengthening surveil-lance and good infection control practices in this hospital.

The burden and characteristics of nosocomial infections in an intensive care unit: A cross-sectional study of clinical and nonclinical samples at a tertiary hospital of Nepal

Background

Patients at intensive care units (ICUs) are vulnerable to acquiring nosocomial infections. The main objective of this study was to explore and characterize the burden of nosocomial infections from an ICU of National Medical College and Teaching Hospital (NMCTH), Birgunj, Nepal.

Methods

A prospective hospital-based study was conducted between April and December 2018 at NMCTH, Birgunj, Province 2, of Nepal. A total of 374 specimens including clinical specimens (n = 190) from patients admitted in an ICU and animate and inanimate environmental samples (n = 184) from the ICU were collected. Collected specimens were cultured in specific microbiological media, and microbial isolates were identified and subjected to antibiotic susceptibility test.

Results

Altogether, 374 specimens (190 clinical specimens and 184 nonclinical) of an ICU were analyzed. Out of 190 clinical specimens, 51% (97/190) showed bacterial growth. Isolated bacteria were Staphylococcus aureus (33%; 32/97), Escherichia coli (20.6%; 20/97), Klebsiella spp. (15.5%; 15/97), Pseudomonas spp. (11.3%; 11/97), and Acinetobacter spp. (11.3%; 11/97). Out of 184 nonclinical specimens, 51.6% (95/184) of the samples showed microbial growth. Among the isolates, Klebsiella spp. predominated (30.6%; 26/85) the growth, followed by S. aureus (22.4%; 19/85), Acinetobacter spp. (21.2%; 18/85), and Pseudomonas spp. (17.6%; 15/85). Among all clinical and nonclinical isolates, 61.9% (60/97) of the clinical specimens and 65.9% (56/85) of the nonclinical specimens showed multidrug resistance (MDR).

Conclusion

Two-thirds of the specimens from both clinical and nonclinical specimens showed MDR. Urgent actions are required to address the augmented rate of nosocomial infections and MDR bacteria among ICUs in Nepal.

Why do people purchase antibiotics over-the-counter? A qualitative study with patients, clinicians and dispensers in central, eastern and western Nepal

Introduction

Over-the-counter (OTC) use of antibiotics contributes to the burgeoning rise in antimicrobial resistance (AMR). Drawing on qualitative research methods, this article explores the characteristics of OTC sales of antibiotic in Nepal, its drivers and implications for policy.

Methods

Data were collected in and around three tertiary hospitals in eastern, western and central Nepal. Using pre-defined guides, a mix of semi-structured interviews and focus group discussions were conducted with dispensers at drug stores, patients attending a hospital and clinicians. Interviews were audio-recorded, translated and transcribed into English and coded using a combination of an inductive and deductive approach.

Results

Drug shops were the primary location where patients engaged with health services. Interactions were brief and transactional: symptoms were described or explicit requests for specific medicine made, and money was exchanged. There were economic incentives for clients and drug stores: patients were able to save money by bypassing the formal healthcare services. Clinicians described antibiotics as easily available OTC at drug shops. Dispensing included the empirical use of broad-spectrum antibiotics, often combining multiple antibiotics, without laboratory diagnostic and drug susceptibility testing. Inappropriately short regimens (2–3 days) were also offered without follow-up. Respondents viewed OTC antibiotic as a convenient alternative to formal healthcare, the access to which was influenced by distance, time and money. Respondents also described the complexities of navigating various departments in hospitals and little confidence in the quality of formal healthcare. Clinicians and a few dispensers expressed concerns about AMR and referred to evadable policies around antibiotics use and poor enforcement of regulation.

Conclusions

The findings point to the need for clear policy guidance and rigorous implementation of prescription-only antibiotics.

Use of antimicrobials and antimicrobial resistance in Nepal: a nationwide survey

Nepal suffers from high burden of antimicrobial resistance (AMR) due to inappropriate use of antibiotics. The main objective of this study was to explore knowledge, attitude and practices of antibiotics uses among patients, healthcare workers, laboratories, drug sellers and farmers in eight districts of Nepal. A cross-sectional survey was conducted between April and July 2017. A total of 516 individuals participated in a face-to-face interview that included clinicians, private drug dispensers, patients, laboratories, public health centers/hospitals and, livestock and poultry farmers. Out of 516 respondents, 62.8% (324/516) were patients, 16.9% (87/516) were clinicians, 6.4% (33/516) were private drug dispensers. A significant proportion of patients (42.9%; 139/324) thought that fever could be treated with antibiotics. Majority (79%; 256/324) of the patients purchased antibiotics over the counter. The knowledge of antibiotics used among patients increased proportionately with the level of education: literate only [AOR = 1.4 (95% Cl = 0.6-4.4)], versus secondary education (8-10 grade) [AOR = 1.8 (95% Cl = 1.0-3.4)]. Adult patients were more aware of antibiotic resistance. Use of antibiotics over the counter was found high in this study. Knowledge, attitude and practice related to antibiotic among respondents showed significant gaps and need an urgent effort to mitigate such practice.

Bacterial Profile and Antibiotic Resistance among Cancer Patients with Urinary Tract Infection in a National Tertiary Cancer Hospital of Nepal

Cancer patients are at high risk of antibiotic resistant bacterial urinary tract infections (UTIs). In this study, we assessed the bacterial profile and antibiotic resistance among cancer patients suspected of UTI in B.P. Koirala Memorial Cancer Hospital in Nepal through a cross-sectional study with routinely collected data. All cancer patients who had a recorded urine culture between July 2018-June 2019 were included in the study. Out of 308 patients who had undergone culture, 73 (24%) of samples had bacterial growth. The most common organisms isolated were E. coli (58%), Staphylococcus (11%) and Klebsiella (10%). These bacteria had undergone susceptibility testing to 27 different antibiotics in various proportions. Of the limited antibiotic testing levels, nitrofurantoin (54/66, 82%) and amikacin (30/51, 59%) were the most common. Among those tested, there were high levels of resistance to antibiotics in the "Access" and "Watch" groups of antibiotics (2019 WHO classification). In the "Reserve" group, both antibiotics showed resistance (polymyxin 15%, tigecycline 8%). Multidrug resistance was seen among 89% of the positive culture samples. This calls for urgent measures to optimize the use of antibiotics in UTI care at policy and health facility levels through stewardship to prevent further augmentation of antibiotic resistance among cancer patients.

Detection of TEM and CTX-M Genes in Escherichia coli Isolated from Clinical Specimens at Tertiary Care Heart Hospital, Kathmandu, Nepal

Background: Antimicrobial resistance (AMR) among Gram-negative pathogens, predominantly ESBL-producing clinical isolates, are increasing worldwide. The main aim of this study was to determine the prevalence of ESBL-producing clinical isolates, their antibiogram, and the frequency of ESBL genes (bla_TEM and bla_CTX-M) in the clinical samples from patients. Methods: A total of 1065 clinical specimens from patients suspected of heart infections were collected between February and August 2019. Bacterial isolates were identified on colony morphology and biochemical properties. Thus, obtained clinical isolates were screened for antimicrobial susceptibility testing (AST) using modified Kirby–Bauer disk diffusion method, while ESBL producers were identified by using a combination disk diffusion method. ESBL positive isolates were further assessed using conventional polymerase chain reaction (PCR) to detect the ESBL genes bla_TEM and bla_CTX-M. Results: Out of 1065 clinical specimens, 17.8% (190/1065) showed bacterial growth. Among 190 bacterial isolates, 57.4% (109/190) were Gram-negative bacteria. Among 109 Gram-negative bacteria, 40.3% (44/109) were E. coli, and 30.2% (33/109) were K. pneumoniae. In AST, 57.7% (n = 63) Gram-negative bacterial isolates were resistant to ampicillin and 47.7% (n = 52) were resistant to nalidixic acid. Over half of the isolates (51.3%; 56/109) were multidrug resistant (MDR). Of 44 E. coli, 27.3% (12/44) were ESBL producers. Among ESBL producer E. coli isolates, 58.4% (7/12) tested positive for the bla_CTX-M gene and 41.6% (5/12) tested positive for the bla_TEM gene. Conclusion: Half of the Gram-negative bacteria in our study were MDR. Routine identification of an infectious agent followed by AST is critical to optimize the treatment and prevent antimicrobial resistance.

Antibiotics' Use in Thailand: Community Pharmacists' Knowledge, Attitudes and Practices

Thailand spends $203 million on antibiotics every year, and patients can still access antimicrobials over the counter without a prescription. Community pharmacy plays a pivotal role in improving access and ensuring the appropriate use of antimicrobials. However, little is known about current practices in this setting. This study aims to assess Thai community pharmacists’ knowledge, attitudes and practices (KAP) regarding antimicrobials’ use and resistance. A cross-sectional study was conducted in Bangkok and Chonburi province in 2017 using an online self-administered questionnaire. The questionnaire was completed by 372 community pharmacists (71.4% response rate). The most commonly encountered infections in the community were upper and lower respiratory tract infections. The most commonly dispensed antimicrobials were broad-spectrum antibiotics including aminopenicillins and fluoroquinolones. Thai pharmacists have a good knowledge, attitude, and practice regarding antimicrobials’ use and resistance. They dispense anti-microbials in line with local guidelines, although international guidelines may not indicate anti-biotics for viral self-limiting infections. While community pharmacy in Thailand could be the most accessible healthcare resource for patients, inappropriate provision of antimicrobials for self-limiting viral infections by pharmacists will increase antimicrobial resistance. This highlights the need for updated guidance and improved pharmacists’ training.

Plasmid-Mediated AmpC β-Lactamase CITM and DHAM Genes Among Gram-Negative Clinical Isolates

Background

Antibiotic resistance mediated by the production of extended-spectrum β-lactamases (ESBLs) and AmpC β-lactamases is posing a serious threat in the management of the infections caused by Gram-negative pathogens. The aim of this study was to determine the prevalence of two AmpC β-lactamases genes, bla_CITM and bla_DHAM, in Gram-negative bacterial isolates.

Materials and Methods

A total of 1151 clinical samples were obtained and processed at the microbiology laboratory of Annapurna Neurological Institute and Allied Science, Kathmandu between June 2017 and January 2018. Gram-negative isolates thus obtained were tested for antimicrobial susceptibility testing (AST) using Kirby–Bauer disk diffusion method. AmpC β-lactamase production was detected by disk approximation method using phenylboronic acid (PBA). Confirmed AmpC β-lactamase producers were further screened for bla_CITM and bla_DHAM genes by conventional polymerase chain reaction (PCR).

Results

Out of 1151 clinical specimens, 22% (253/1152) had bacterial growth. Of the total isolates, 89.3% (226/253) were Gram-negatives, with E. coli as the most predominant species (n=72) followed by Pseudomonas aeruginosa (n=41). In the AST, 46.9% (106/226) of the Gram-negative isolates were multidrug resistant (MDR). In disk diffusion test, 113 (50%) isolates showed resistance against cefoxitin, among which 91 isolates (83 by disk test and Boronic acid test, 8 by Boronic test only) were confirmed as AmpC β-lactamase-producers. In PCR assay, 90.1% (82/91) and 87.9% (80/91) of the isolates tested positive for production of bla_CITM and bla_DHAM genes, respectively.

Conclusions

High prevalence of AmpC β-lactamase-producers in our study is an alarming sign. This study recommends the use of modern diagnostic facilities in the clinical settings for early detection and management which can optimize the treatment therapies, curb the growth and spread of the drug-resistant pathogens.

Antimicrobial use in food animals and human health: time to implement 'One Health' approach

The use of antimicrobials in animals for growth promotion and infection prevention significantly contributes to the development of antimicrobial resistance (AMR), a growing public health threat. While the World Health Organization (WHO), the United Nations (UN) and the European Union (EU) have taken steps towards reducing and restricting the use of antimicrobials in animals, initiatives are insufficient in developing countries where the demands for food animals continue to rise over the years. The inter-sectoral acknowledgment of inextricable link between animal health, human health and the environment (One Health approach) is critical. Concerted and collaborative efforts among all the stakeholders are essential to deal with this complex problem of resistance.

Plasmid mediated colistin resistant mcr-1 and co-existence of OXA-48 among Escherichia coli from clinical and poultry isolates: first report from Nepal

Background

Plasmid-mediated resistance to the last-resort drugs: carbapenems and colistin is an emerging public health threat. The studies on the prevalence and co-expression of resistant genes among livestock and human pathogens are rare in Nepal. This is the first study in Nepal exploring the prevalence and co-existence of colistin resistance gene, mcr-1 along with carbapenemase resistance gene, OXA-48 in Escherichia coli isolated from poultry and clinical specimens.

Methods

A total of 240 rectal swabs from chickens of five different poultry farms of Kathmandu valley and 705 mid-stream urine samples from human subjects attending Kantipur Hospital, Kathmandu were collected between August, 2018 and March, 2019. Rectal swabs and urine specimens were cultured. E. coli isolated from the specimens were screened for antimicrobial susceptibility testing (AST) using disk diffusion method’. Minimum inhibitory concentration (MIC) of colistin was determined by agar dilution method using 0.5 µg/ml to 32 µg/ml. The E. coli isolates were first screened for mcr-1 followed by screening for OXA-48 genes using conventional Polymerase chain reaction (PCR).

Results

Of the total samples analyzed, E. coli was isolated from 31.7% (76/240) of poultry and 7.9% (56/705) of clinical specimens. In AST, 80% (61/76) of E. coli from poultry and 79% (44/56) from clinical specimens were MDR. The phenotypic prevalence of colistin resistance in poultry specimens were 31.6% (24/76) and clinical specimens were 21.4% (12/56). In PCR assay, 27.6% (21/76) of poultry and 19.6% (11/56) of clinical isolates had colistin resistant mcr-1 gene. MICs value of E. coli isolates ranged from 4 to 32 (µg/ml) in both clinical and poultry isolates. Prevalence of co-existing carbapenem resistance gene, OXA-48, among colistin resistant mcr-1 positive isolates was 38% (8/21) in poultry specimens and 18.2% (2/11) in clinical specimens.

Conclusions

The high prevalence of colistin and carbapenem resistant genes, and their co-existence in plasmid DNA of E. coli isolates in this study suggests the possible spread to other animal, human and environmental pathogens. Molecular methods in addition to the conventional diagnostics in laboratories can help in early diagnosis, effective management and control of their potential transmission.

Setting the standard: multidisciplinary hallmarks for structural, equitable and tracked antibiotic policy

There is increasing concern globally about the enormity of the threats posed by antimicrobial resistance (AMR) to human, animal, plant and environmental health. A proliferation of international, national and institutional reports on the problems posed by AMR and the need for antibiotic stewardship have galvanised attention on the global stage. However, the AMR community increasingly laments a lack of action, often identified as an 'implementation gap'. At a policy level, the design of internationally salient solutions that are able to address AMR's interconnected biological and social (historical, political, economic and cultural) dimensions is not straightforward. This multidisciplinary paper responds by asking two basic questions: (A) Is a universal approach to AMR policy and antibiotic stewardship possible? (B) If yes, what hallmarks characterise 'good' antibiotic policy? Our multistage analysis revealed four central challenges facing current international antibiotic policy: metrics, prioritisation, implementation and inequality. In response to this diagnosis, we propose three hallmarks that can support robust international antibiotic policy. Emerging hallmarks for good antibiotic policies are: Structural, Equitable and Tracked. We describe these hallmarks and propose their consideration should aid the design and evaluation of international antibiotic policies with maximal benefit at both local and international scales.

Health system's readiness to provide cardiovascular, diabetes and chronic respiratory disease related services in Nepal: analysis using 2015 health facility survey

BACKGROUND

The burgeoning rise of non-communicable diseases (NCDs) is posing serious challenges in resource constrained health facilities of Nepal. The main objective of this study was to assess the readiness of health facilities for cardiovascular diseases (CVDs), diabetes and chronic respiratory diseases (CRDs) services in Nepal.

METHODS

This study utilized data from the Nepal Health Facility Survey 2015. General readiness of 940 health facilities along with disease specific readiness for CVDs, diabetes, and CRDs were assessed using the Service Availability and Readiness Assessment manual of the World Health Organization. Health facilities were categorized into public and private facilities.

RESULTS

Out of a total of 940 health facilities assessed, private facilities showed higher availability of items of general service readiness except for standard precautions for infection prevention, compared to public facilities. The multivariable adjusted regression coefficients for CVDs (β = 2.87, 95%CI: 2.42-3.39), diabetes (β =3.02, 95%CI: 2.03-4.49), and CRDs (β = 15.95, 95%CI: 4.61-55.13) at private facilities were higher than the public facilities. Health facilities located in the hills had a higher readiness index for CVDs (β = 1.99, 95%CI: 1.02-1.39). Service readiness for CVDs (β = 1.13, 95%CI: 1.04-1.23) and diabetes (β = 1.78, 95%CI: 1.23-2.59) were higher in the urban municipalities than in rural municipalities. Finally, disease-related services readiness index was sub-optimal with some degree of variation at the province level in Nepal. Compared to province 1, province 2 (β = 0.83, 95%CI: 0.73-0.95) had lower, and province 4 (β =1.24, 95%CI: 1.07-1.43) and province 5 (β =1.17, 95%CI: 1.02-1.34) had higher readiness index for CVDs.

CONCLUSION

This study found sub-optimal readiness of services related to three NCDs at the public facilities in Nepal. Compared to public facilities, private facilities showed higher readiness scores for CVDs, diabetes, and CRDs. There is an urgent need for policy reform to improve the health services for NCDs, particularly in public facilities.

Detection of OXA-48 Gene in Carbapenem-Resistant Escherichia coli and Klebsiella pneumoniae from Urine Samples

INTRODUCTION

Resistance to carbapenem in Gram-negative bacteria is attributable to their ability to produce carbapenemase enzymes. The main objective of this study was to detect the presence of blaOXA-48 genes in carbapenem-resistant uropathogenic Escherichia coli and Klebsiella pneumoniae isolated from urine samples from patients attending Alka Hospital, Jawalakhel, Lalitpur, Nepal.

METHODS

A total of 1013 mid-stream urine samples were collected from patients with suspected urinary tract infection (UTI) between April and September 2018. The identified isolates underwent antibiotic susceptibility testing using the modified Kirby-Bauer disc-diffusion method. Phenotypic carbapenemase production was confirmed by the modified Hodge test, and the blaOXA-48 gene was detected using conventional polymerase chain reaction.

RESULTS

Out of 1013 urine samples, 15.2% (154/1013) had bacterial growth. Among the isolates, 91.5% (141/154) were Gram-negative bacteria, and E. coli was the most common bacterial isolate (62.9%; 97/154), followed by K. pneumoniae 15.6% (24/154). Among 121 bacterial isolates (97 E. coli isolates and 24 K. pneumoniae isolates), 70.3% (52/121) were multidrug-resistant E. coli and 29.7% (22/121) were multidrug-resistant K. pneumoniae. In addition, 9.1% (11/121) were carbapenem resistant (both imipenem and meropenem resistant). Development of multidrug resistance and development of carbapenem resistance were significantly associated (p<0.05). Of the 11 carbapenem-resistant isolates, only seven were carbapenemase producers; of these, 28.6% (2/7) were E. coli, 72.4% (5/7) were K. pneumoniae and 42.8% (3/7) had the blaOXA-48 gene. Of the three bacterial isolates with the blaOXA-48 gene, 33.3% (1/3) were E. coli and 66.7% (2/3) were K. pneumoniae.

CONCLUSION

One in ten isolates of E. coli and K. pneumoniae were carbapenem resistant. Among carbapenem-resistant isolates, one-third of E. coli and two-thirds of K. pneumoniae had the blaOXA-48 gene. OXA-48 serves as a potential agent to map the distribution of resistance among clinical isolates.
