Effect of rotavirus vaccination on the burden of rotavirus disease and associated antibiotic use in India: A dynamic agent-based simulation analysis. Vaccine 2024; 42:126211. [PMID: 39137492 PMCID: PMC11385704 DOI: 10.1016/j.vaccine.2024.126211] [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: 05/21/2024] [Revised: 07/29/2024] [Accepted: 08/05/2024] [Indexed: 08/15/2024]
Abstract
BACKGROUND Rotavirus is a leading cause of diarrhea in infants and young children in many low- and middle-income countries. India launched a childhood immunization program for rotavirus in 2016, starting with four states and expanding it to cover all states by 2019. The objective of this study was to estimate the effects of the rotavirus vaccination program in India on disease burden and antibiotic misuse. METHODS We built a dynamic agent-based model of rotavirus progression in children under five within each district in India. Simulations were run for various scenarios of vaccination coverage in the context of India's Universal Immunization Programme. Population data were obtained from the National Family Household Surveys and used to calibrate the models. Disease parameters were obtained from published studies. We estimated past and projected future reduction of disease burden and antibiotic misuse due to full vaccination nationwide, by state, and by wealth quintile. RESULTS We estimate that rotavirus vaccination in India has reduced the prevalence of rotavirus cases by 33.7% (prediction interval: 30.7-36.0%), total antibiotic misuse due to rotavirus by 21.8% (18.6-25.1%), and total deaths due to rotavirus by 38.3% (31.3-44.4%) for children under five. We estimate total antibiotic misuse due to rotavirus infection to be 7.6% (7.5-7.9%) of total antibiotic consumption in this demographic versus 9.6% (9.4-9.9%) in the absence of vaccination. We project rotaviral prevalence to drop to below one case for every 100,000 individuals in those below five if vaccination coverage is increased by 50.3% (45.2-58.5%) to 68.1% (63.1-76.4) nationwide. CONCLUSION Universal coverage of childhood rotavirus vaccination can substantially reduce inappropriate antibiotic use in India.

Abstract
The present study aimed to determine the presence of Klebsiella pneumoniae and Escherichia coli with extended-spectrum β-lactamase (ESBL)s property from treated wastewater effluents. Treated effluent samples were collected from two major water treatment plants which located at Avaniyapuram and Sakkimangalam, Madurai, Tamil Nadu, India. Among the 51 isolates, 56.86 % represented E. coli (18 from Avaniyapuram and 11 from Sakkimangalam) and 43.14 % were K. pneumoniae (7 from Avaniyapuram and 15 from Sakkimangalam). Based on the ESBL propensity, E. coli was overrepresented in the present study. All the isolates turned positive for ESBL, while 5.88 % of K. pneumoniae and 7.84 % of E. coli were positive for carbapenemases. Further, K. pneumoniae isolates from both sites showed 100 % resistance to beta-lactams, with resistance to other antibiotics such as tetracycline and meropenem. E. coli isolates were 100 % resistant to ceftazidime and cefuroxime, and 88.9 % were resistant to amoxicillin/clavulanate and ceftriaxone. The MAR indices observed in the present study for E. coli and K. pneumoniae were above the threshold value of 0.2 suggested a high risk of environmental contamination. These findings highlighted the need for routine surveillance at appropriate intervals for the presence of ESBL producing pathogens and other MDR pathogens in the environment to provide proper clinical management, develop various counter measures and policies to address and halt the spread of such potential threats.

Abstract
The current study explored the resistomes and viromes of three Indian ethnic populations: Jaisalmer, Khargone, and Ladakh. These three groups had different dietary habits and antibiotic consumption rates. A resistome analysis indicated that compared to the Jaisalmer (n = 10) group, the burden of antibiotic resistance genes in the gut microbiome was higher in the Khargone (n = 12) and Ladakh (n = 9) groups. However, correlational analysis factoring in food habits, healthcare, and economic status was not statistically significant due to the limited number of samples. A considerable number of antibiotic resistance genes (ARGs) were present in well-known gut commensals such as Bifidobacteriaceae, Acidomonococcaceae, etc., as retrieved directly by mapping to the Resfinder database using the Groot tool. Further, the raw reads were assembled using MEGAHIT, and putative bacteriophages were retrieved using the VIBRANT tool. Many of the classified bacteriophages of the virome revealed that bacteria belonging to the families Bifidobacteriaceae and Enterocococcaceae were their hosts. The prophages identified in these groups primarily contained auxiliary metabolic genes (AMGs) for primary amino acid metabolism. However, there were significantly fewer AMGs in the Ladakh group than in the Jaisalmer group (p < 0.05). None of the classified bacteriophages or prophages contained ARGs. This indicates that phages do not normally carry antibiotic resistance genes.

Abstract
Being a macrolide antibiotic, the antiviral and anti-inflammatory properties of azithromycin (AZM) were taken advantage of during the COVID-19 pandemic which led to the overuse of AZM resulting in excessive release and accumulation in the waterways and ecosystem causing unpleasant threats to humankind. This demands the necessity for a highly sensitive material being capable of recognizing AZM in wastewater. Mindful of the optical attributes of organic ligand structures, we have constructed a hybrid material by chelating Zn2+ with pyridyl benzimidazole (PBI). The prepared sensor material ZnPBI was characterized using various microscopic and spectroscopic techniques including XRD, FT-IR, HR-SEM, HR-TEM, etc. The proposed sensor material exhibited proficient detection performance selectively towards AZM with a very low detection limit of 72 nM. Two linear ranges between 0 - 70 μM and 70-100 μM were observed corresponding to two different mechanistic pathways. To the best of our knowledge, the utilization of a metal-organic complex (MOC) for the fluorometric detection of AZM has not been explored so far. It is creditworthy to cite that the long-term structural stability of the sensor material was maintained for 100 days in water and it can be reused three times without any depreciation in the sensing activity. A combination of energy transfer routes, adsorption and electrostatic interactions for AZM detection are described experimentally and theoretically which provides insights into the role of MOC as sensing probes.

Abstract
The consumption of antibiotics varies between and within countries. However, our understanding of the key drivers of antibiotic consumption is largely limited to observational studies. Using Indian data that showed substantial differences between states and changes over years, we conducted a quasi-experimental fixed-effects regression study to examine the determinants of private-sector antibiotic consumption. Antibiotic consumption decreased by 10.2 antibiotic doses per 1000 persons per year for every ₹1000 (US$12.9) increase in per-capita gross domestic product. Antibiotic consumption decreased by 46.4 doses per 1000 population per year for every 1% increase in girls' enrollment rate in tertiary education. The biggest determinant of private sector antibiotic use was government spending on health-antibiotic use decreased by 461.4 doses per 1000 population per year for every US$12.9 increase in per-capita government health spending. Economic progress, social progress, and increased public investment in health can reduce private-sector antibiotic use.

Abstract
Background Consumption of injectable antibiotics is not widely studied, despite injectables constitute a major share of antibiotic cost. This study aimed to understand the share of oral and injectable antibiotic consumption and cost at the national level in India, and the public and private sector shares in the provision and cost of injectables in Kerala state. Methods We used the PharmaTrac private sector sales dataset and the Kerala Medical Services Corporation public sector procurement dataset. Using WHO Access, Watch, Reserve (AWaRe) and Anatomical Therapeutic Chemical (ATC) Classifications, we estimated the annual total and per-capita consumption, and the annual total, per defined daily dose (DDD), and per-capita spending on injectables. Results Although 94.9% of total antibiotics consumed at the national level were oral preparations, 35.8% of total spending were on injectables. In Kerala , around 33% of total antibiotic spending in the private sector were for injectables, compared to around 25% in the public sector. The public sector used fewer injectable antibiotic formulations (n=21) compared the private sector (n=69). The cost per DDD was significantly higher in the private sector as compared to the public sector. Despite only accounting for 6.3% of the cost share, the public sector provided 31.4% of injectables, indicating very high efficiency. Across both sectors, Watch group antibiotics were significantly more consumed and at a significantly higher cost than Access group antibiotics, for example in nearly double the quantity and at 1.75 times the price per DDD in the private sector. Reserve group antibiotics made up the lowest consumption share (0.61% in the private sector), but at the highest cost per DDD (over 16 times that of Access). Conclusions Public sector showed higher cost efficiency in antibiotic provisioning compared to private sector. Appropriate antibiotic use cannot be achieved through drug price control alone but requires extensive engagement with private providers through structured stewardship programs.

Ten-year trends of antibiotic prescribing in surgery departments of two private sector hospitals in Central India: a prospective observational study. BMC Public Health 2024; 24:310. [PMID: 38281052 PMCID: PMC10821557 DOI: 10.1186/s12889-024-17817-2] [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: 11/02/2023] [Accepted: 01/19/2024] [Indexed: 01/29/2024] Open
Abstract
BACKGROUND Inappropriate antibiotic use contributes to the global rise of antibiotic resistance, prominently in low- and middle-income countries, including India. Despite the considerable risk of surgical site infections, there is a lack of antibiotic prescribing guidelines and long-term studies about antibiotic prescribing in surgery departments in India. Therefore, this study aimed to analyse 10 years' antibiotic prescribing trends at surgery departments in two tertiary-care hospitals in Central India. METHODS Data was prospectively collected from 2008 to 2017 for surgery inpatients in the teaching (TH-15,016) and the non-teaching hospital (NTH-14,499). Antibiotics were classified based on the World Health Organization (WHO) Access Watch Reserve system and analysed against the diagnoses and adherence to the National List of Essential Medicines India (NLEMI) and the WHO Model List of Essential Medicines (WHOMLEM). Total antibiotic use was calculated by DDD/1000 patient days. Time trends of antibiotic prescribing were analysed by polynomial and linear regressions. RESULTS The most common indications for surgery were inguinal hernia (TH-12%) and calculus of the kidney and ureter (NTH-13%). The most prescribed antibiotics were fluoroquinolones (TH-20%) and 3rd generation cephalosporins (NTH-41%), and as antibiotic prophylaxis, norfloxacin (TH-19%) and ceftriaxone (NTH-24%). Access antibiotics were mostly prescribed (57%) in the TH and Watch antibiotics (66%) in the NTH. Culture and susceptibility tests were seldom done (TH-2%; NTH-1%). Adherence to the NLEMI (TH-80%; NTH-69%) was higher than adherence to the WHOMLEM (TH-77%; NTH-66%). Mean DDD/1000 patient days was two times higher in the NTH than in the TH (185 vs 90). Overall antibiotic prescribing significantly increased in the TH (β1 =13.7) until 2012, and in the NTH (β2 =0.96) until 2014, and after that decreased (TH, β2= -0.01; NTH, β3= -0.0005). The proportion of Watch antibiotic use significantly increased in both hospitals (TH, β=0.16; NTH, β=0.96). CONCLUSION Total antibiotic use decreased in the last three (NTH) and five years (TH), whereas consumption of Watch antibiotics increased over 10 years in both hospitals. The choice of perioperative antibiotic prophylaxis was often inappropriate and antibiotic prescribing was mostly empirical. The results of this study confirmed the need for antibiotic prescribing guidelines and implementation of antimicrobial stewardship programs.

Phenotypic Detection of Carbapenemase and AmpC-β-Lactamase Production among Extended Spectrum β-Lactamase (ESBL)-Producing Escherichia coli and Klebsiella spp. Isolated from Clinical Specimens. Antibiotics (Basel) 2023; 13:31. [PMID: 38247589 PMCID: PMC10812623 DOI: 10.3390/antibiotics13010031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 12/18/2023] [Accepted: 12/21/2023] [Indexed: 01/23/2024] Open
Abstract
Introduction: Data on antimicrobial resistance (AMR) are sparse across numerous African countries, as microbiological analyses are not routinely conducted and surveillance data are not collected. Accordingly, clinical samples are not routinely tested for carbapenem-resistant bacteria and, therefore, the general understanding of their prevalence in the region remains limited. Methods: Between January 2020 and June 2022, we collected extended spectrum β-lactamase (ESBL)-producing Enterobacterales (ESBL-PE) isolates from five hospitals in Burkina Faso. After an initial culture on ESBL-selective media, the species were identified using API20E and isolates were tested against 13 antimicrobial agents using the disc diffusion method on Mueller-Hinton (MH) agar. ESBL production was confirmed via a double-disc synergy test. Production of carbapenemases and AmpC-β-lactamases and phenotypic co-resistance were determined. Results: Among the 473 ESBL-PE, 356 were ESBL-E. coli (ESBL-Ec) and 117 were Klebsiella spp. (ESBL-K). Of these isolates, 5.3% were carbapenemase and 5.3% were AmpC-β-lactamase-positive. Three types of carbapenemases were identified: 19 NDM, 3 OXA-48-like and 1 VIM. Two isolates produced both NDM and OXA-48-like carbapenemases. Carbapenemase producers were detected at all levels of healthcare. Co-resistance rates were up to 85% for aminoglycosides, 90% for sulfonamides, 95% for fluoroquinolones and 25% for chloramphenicol. Fosfomycin resistance was 6% for ESBL-Ec and 49% for ESBL-K (49%). Conclusions: Some of the ESBL-Ec and ESBL-K co-produced carbapenemases and/or AmpC-β-lactamases at all healthcare levels and in various sample types with high co-resistance rates to non-betalactams. Carbapenem resistance is no longer rare, calling for testing in routine diagnostics, a comprehensive resistance surveillance system and infection control within healthcare.

Abstract
A survey on antibiotic literacy in terms of the use and abuse of antibiotics to track and understand antibiotic consumption is crucial to optimize the use of antibiotics and minimizing antimicrobial resistance (AMR). Purposive random sampling, using the snow-ball questionnaire technique, was adopted to ensure that the respondents distributed across India, coming from rural and urban settings, were adolescents as well as adults and had completed at least the higher secondary school level of education. Respondents were divided into five subcategories. The questionnaire was distributed between April 2021 and July 2021, during the second COVID-19 wave in India. The survey questionnaire included 34 questions, comprising multiple-choice and 5-point Likert scale-type questions. This study composed of 972 respondents. Most respondents considered antibiotics safe and frequently failed to discriminate between the symptoms of bacterial and viral infections, most often leading to self-prescription. About 34% of the rural participants and 50% of the urban participants considered antibiotic resistance a serious health concern. Antibiotic prescriptions by the medical or paramedical practitioner were largely empirical. At least 95% of participants acknowledged having heard about antibiotics; nearly 20% of antibiotic consumption came from nonprescription users, while 30% had not completed their antibiotic therapy for a variety of reasons. Sixty-two percent consumed antibiotics to treat cold and flu symptoms. Results from the survey suggest the presence of a crucial gap between the respondents' perception of antibiotics and levels of information regarding antibiotic use and misuse. The present study may serve as a benchmark that strongly recommends a financially feasible policy, which includes educating society regarding the spread of AMR and its severe consequences by incorporating AMR into the curriculum at the levels of senior secondary school and higher education.

Abstract
The challenge of emerging contaminants (ECs) in global surface water bodies and particularly in low- and middle-income countries such as India, Pakistan, Bangladesh, and Sri Lanka, is evident from the literature. The complexity arises from the high costs involved in EC analysis and the extensive list of ECs, which complicates the selection of essential compounds for scientific and regulatory investigations. Consequently, monitoring programs often include ECs that may have minimal significance within a region and do not pose known or suspected ecological or human health risks. This study aims to address this issue by employing a multi-risk assessment approach to identify priority ECs in the surface waters of the aforementioned countries. Through an analysis of occurrence levels and frequency data gathered from published literature, an optimized risk quotient (RQ) was derived. The findings reveal a priority list of 38 compounds that exhibit potential environmental risks and merit consideration in future water quality monitoring programs. Furthermore, the majority of antibiotics in India (12 out of 17) and Pakistan (7 out of 17) exhibit a risk quotient for antimicrobial resistance selection (RQAMR) greater than 1, highlighting the need for devising effective strategies to mitigate the escalation of antibiotic resistance in the environment.

Smout E, Palanisamy N, Valappil SP. Prevalence of vancomycin-resistant Enterococci in India between 2000 and 2022: a systematic review and meta-analysis. Antimicrob Resist Infect Control 2023; 12:79. [PMID: 37605268 PMCID: PMC10441759 DOI: 10.1186/s13756-023-01287-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Accepted: 08/10/2023] [Indexed: 08/23/2023] Open
Abstract
BACKGROUND Vancomycin-resistant Enterococci (VRE) infections are recurrently reported in different parts of India in the last two decades. However, an up-to-date, countrywide information concerning the prevalence and the rate of VRE in India is limited and hence this study aimed to estimate the pooled prevalence of VRE in India. METHODS A literature search was performed using various databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed throughout. Cross-sectional studies reporting the prevalence of VRE in India from human samples whereby at least two Enterococci were isolated between 1 January 2000 and 31 December 2022 were sought for inclusion. Data were extracted and analysed using Microsoft Excel and Comprehensive Meta-analysis version 4, respectively. RESULTS Nineteen studies were included in the analyses. A collective total of 3683 Enterococci isolates were examined, of which 368 were VRE strains. The pooled prevalence of VRE in India was calculated at 12.4% (95% CI: 8.6-17.5; Q = 189.69; I2 = 90.51%; p = < 0.001). E. faecalis was the most frequently isolated species (1450 [39.37%]) followed by E. faecium (724 [19.66%]). Amongst the VRE strains, E. faecium was the most prevalent (214 [58.15%]) followed by E. faecalis (134 [36.41%]). An upsurge in the rate of VRE infections was observed in India over time: VRE prevalence was estimated at 4.8% between 2000 and 2010 and 14.1% between 2011 and 2020. CONCLUSION This study presents the most up-to-date information on the rate of VRE infections in India. Though lower than the findings for some less developed countries, VRE prevalence in India is notable and on the rise.

Avatsingh AU, Sharma S, Kour S, Arora Y, Sharma S, Joshi D, Chaudhary PP, Perveen K, Kamal MA, Singh N. Prevalence of antibiotic-resistant Gram-negative bacteria having extended-spectrum β-lactamase phenotypes in polluted irrigation-purpose wastewaters from Indian agro-ecosystems. Front Microbiol 2023; 14:1227132. [PMID: 37608947 PMCID: PMC10440439 DOI: 10.3389/fmicb.2023.1227132] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Accepted: 07/25/2023] [Indexed: 08/24/2023] Open
Abstract
Antibiotic resistance in bacteria has emerged as a serious public health threat worldwide. Aquatic environments including irrigation-purpose wastewaters facilitate the emergence and transmission of antibiotic-resistant bacteria and antibiotic resistance genes leading to detrimental effects on human health and environment sustainability. Considering the paramount threat of ever-increasing antibiotic resistance to human health, there is an urgent need for continuous environmental monitoring of antibiotic-resistant bacteria and antibiotic resistance genes in wastewater being used for irrigation in Indian agro-ecosystems. In this study, the prevalence of antibiotic resistance in Gram-negative bacteria isolated from irrigation-purpose wastewater samples from Sirmaur and Solan districts of Himachal Pradesh was determined. Bacterial isolates of genera Escherichia, Enterobacter, Hafnia, Shigella, Citrobacter, and Klebsiella obtained from 11 different geographical locations were found to exhibit resistance against ampicillin, amoxyclav, cefotaxime, co-trimoxazole, tobramycin, cefpodoxime and ceftazidime. However, all the isolates were sensitive to aminoglycoside antibiotic gentamicin. Enterobacter spp. and Escherichia coli showed predominance among all the isolates. Multidrug-resistance phenotype was observed with isolate AUK-06 (Enterobacter sp.) which exhibited resistant to five antibiotics. Isolate AUK-02 and AUK-09, both E. coli strains showed resistant phenotypes to four antibiotics each. Phenotypic detection revealed that six isolates were positive for extended-spectrum β-lactamases which includes two isolates from Enterobacter spp. and E. coli each and one each from Shigella sp. and Citrobacter sp. Overall, the findings revealed the occurrence of antibiotic resistant and ESBL-positive bacterial isolates in wastewaters utilized for irrigation purpose in the study area and necessitate continuous monitoring and precautionary interventions. The outcomes of the study would be of significant clinical, epidemiological, and agro-environmental importance in designing effective wastewater management and environmental pollution control strategies.
