Objective: To investigate the morbidity due to the mumps epidemic in Navi Mumbai region of Maharashtra during 2023-24 and identify the preventive strategies., Methods: An outbreak investigation was carried by pediatricians in Navi Mumbai, Maharashtra, India, between December 2023 and February 2024. A clinical case of mumps was defined as any person with acute onset of unilateral or bilateral, tender, swelling of the parotid or other salivary gland(s), lasting at least two days., Results: 217 documented cases of mumps were investigated. Among them 197 (90.78%) had never received mumps vaccine, and 20 had received Measles-Mumps-Rubella vaccine (MMR) in the private sector. 185 children had been immunized with Measles-Rubella Vaccine (MR) in the National Immunization programme. The opportunity to vaccinate with the additional component of mumps had been missed during immunization with MR vaccine., Conclusion: This outbreak investigation highlights the need to establish a Public Health Division in the Government for monitoring all contagious diseases in the community and the timely detection and control of all outbreaks.

International spread of polio continues to be a Public Health Emergency of International Concern since its declaration by the World Health Organization in 2014 and its reiteration in 2024. In 2023 and 2024, two countries remained endemic for wild poliovirus (WPV) but 20 countries reported polio outbreaks due to vaccine-derived polioviruses (VDPVs) in 2023 and 10 countries in 2024 (up to mid-June). Guidelines from various agencies recommend polio vaccination before travelling to or from polio-affected countries, or attending mass gatherings anywhere in the world, particularly if the crowd is international. Immunity protects against polio paralysis but not against poliovirus re-infection, irrespective of which vaccine was involved - live attenuated oral polio vaccine (OPV) or inactivated poliovirus vaccine (IPV). Infection with WPV or circulating VDPV in the vast majority of non-immune individuals (first infection) is asymptomatic, while they are efficient virus transmitters. Re-infections in immune individuals are always asymptomatic, but they are also infectious and may act as source for further transmission, although less efficiently than the former. Thus, travellers can become transmission vectors, illustrated by many episodes of importations of WPV or VDPVs into polio-free countries in recent years. The route of poliovirus transmission remains controversial, with many believing it to be faecal-oral, but epidemiological analysis is consistent with respiratory route and not faecal-oral. Transmission occurs person-to-person during social contact. Travellers must ensure they are adequately immunised to avoid polio, and becoming vectors of virus importation. The vaccine efficacy (VE) of OPV is highly variable - high in temperate climate countries, particularly rich countries, but low or very low in tropical low-income countries. On the other hand, VE of IPV is excellent everywhere irrespective of geography., (© The Author(s), 2024.)

Aims: The route of transmission of wild and circulating vaccine-derived polioviruses remains controversial, between respiratory and faecal-oral, and we aim to identify the most plausible one to settle the controversy., Methods: We explored available epidemiological clues and evidence in support of either route in order to arrive at an evidence-based conclusion., Results: Historically the original concept was respiratory transmission based on epidemiological features of age distribution, which was later revised to faecal-oral as the rationale for popularising the live attenuated oral polio vaccine in preference to the inactivated poliovirus vaccine. Through epidemiological logic, we find no evidence for the faecal-oral route from available studies and observations, but all available information supports the respiratory route., Conclusions: The route is respiratory, not faecal-oral. The global polio eradication initiative assumed it was faecal-oral - and its gargantuan efforts based on this assumption have failed in two ways: eradication remains pending and circulating vaccine-derived polioviruses have seeded widely. With clarity on the route of transmission the choice of vaccine is also clear - it can only be the inactivated poliovirus vaccine.

In 2018, the Navi Mumbai Municipal Corporation implemented phase 1 of a public sector typhoid conjugate vaccine campaign in Navi Mumbai, India, targeting all children aged 9 months to 14 years within its administrative boundaries. To assess associations with receipt of vaccine in phase 1, we used generalized estimating equations to calculate estimates of vaccination by child-, household-, and community-level demographics (child education and age; household head education, income, and occupation; community informal settlement percent). Campaign vaccine receipt was most associated with children enrolled in school (odds ratio [OR] = 3.84, 95% CI: 2.18-6.77), the lowest household income tertile when divided into three equal parts (OR = 1.64, 95% CI: 1.43-1.84), and lower community-level socioeconomic status (OR = 1.06, 95% CI: 1.04-1.08 per 10% informal settlement proportion). The campaign was successful in reaching the most underserved populations of its target communities.

Typbar-TCV®, a typhoid conjugate vaccine (TCV), was prequalified by the World Health Organization in 2017. We evaluated its effectiveness in a mass vaccination program targeting children 9 months to 14 years in Navi Mumbai, India, from September 2018 to July 2020. We compared laboratory-confirmed typhoid cases from six clinical sites with age-matched community controls. Of 38 cases, three (8.6%) received TCV through the campaign, compared with 53 (37%) of 140 controls. The adjusted odds ratio of typhoid fever among vaccinated children was 0.16 (95% CI: 0.05-0.55), equivalent to a vaccine effectiveness of 83.7% (95% CI: 45.0-95.3). Vaccine effectiveness of Typbar-TCV in this large public sector vaccine introduction was similar to prior randomized controlled trials, providing reassurance to policymakers that TCV effectiveness is robust in a large-scale implementation.

Aims: To explore if intestinal immunity induced by infection with live viruses in the oral poliovirus vaccine (OPV) is essential, necessary or even helpful in interrupting transmission of wild poliovirus (WPV) for global polio eradication., Methods: We reviewed the biology of virus-host interactions in WPV infection and its alterations by OPV-induced immunity for direct evidence of the usefulness of intestinal immunity. We also explored indirect evidence by way of the effect of the inactivated poliovirus vaccine (IPV) on the biology and on transmission dynamics of WPV., Results: Immunity, systemic and intestinal, induced by infection with WPV or vaccine viruses, does not prevent re-infection with WPV or vaccine viruses respectively, when exposed. Such re-infected hosts shed virus in the throat and in faeces and are sources of further transmission. Immunity protects against polio paralysis-hence reinfection always remain asymptommatic and silent., Conclusion: Vaccine virus-induced intestinal immunity is not necessary for polio eradication. The continued and intensive vaccination efforts using OPV under the assumption of its superiority over IPV have resulted in the well-known undesirable effects, namely vaccine associated paralytic polio and the emergence of de-attenuated circulating vaccine-derived polioviruses, in addition to the delay in completing global WPV eradication.

An outbreak of Hand Foot and Mouth Disease (HFMD) which occurred in August-September, 2022 in Navi Mumbai, India was prospectively investigated, to delineate the clinical manifestations and identify the etiological agent. Molecular characterization at ICMR-National Institute of Virology (NIV), Mumbai unit reported 69 (88.5%) cases out of 78 clinically diagnosed HFMD cases positive for enteroviruses. Thirty-nine (56.5%) children were positive for CVA6, 11 (15.9%) for CVA16, and one for CVA4 (1.4%). One case of co-infection (CVA16, CVA6) was reported. Fourteen (17.9%) cases had recurrent disease in the same season. CVA6 was associated with unusual extension of the rash beyond the conventional areas of hands, feet, and mouth, with involvement of body areas including face, axillae and trunk. Whole genome sequencing classified CVA6 as group D3 and CVA16 isolates as group B1c. Co-infection and recurrence of disease with atypical symptoms observed in this study highlight the need for continued vigilance of the evolutionary clinical characteristics of the enteroviruses causing HFMD., (© 2024.

In the continued battle against one of the oldest enemies known to mankind, Mycobacterium tuberculosis (MTB) , the emergence of drug resistance to antituberculosis drugs among children poses multiple challenges for early detection and treatment. Molecular diagnostics and newer drugs like bedaquiline and delamanid have strengthened the armamentarium and helped design convenient, safe, and child-friendly therapeutic regimens against drug-resistant tuberculosis (TB). Preventive strategies like treatment of TB infection among children living in close contact with patients with drug-resistant TB and effective vaccines against TB are currently in the investigative stages of development and implementation. In addition to the implementation of recent novel diagnostics and treatment modalities, effective psychosocial and nutritional support, as well as dedicated monitoring for compliance and adverse effects, are crucial determinants for successful treatment outcomes in these children.

We performed whole-genome sequencing of 174 Salmonella Typhi and 54 Salmonella Paratyphi A isolates collected through prospective surveillance in the context of a phased typhoid conjugate vaccine introduction in Navi Mumbai, India. We investigate the temporal and geographical patterns of emergence and spread of antimicrobial resistance. We evaluated the relationship between the spatial distance between households and genetic clustering of isolates. Most isolates were non-susceptible to fluoroquinolones, with nearly 20% containing ≥3 quinolone resistance-determining region mutations. Two H58 isolates carried an IncX3 plasmid containing bla SHV-12 , associated with ceftriaxone resistance, suggesting that the ceftriaxone-resistant isolates from India independently evolved on multiple occasions. Among S . Typhi, we identified two main clades circulating (2.2 and 4.3.1 [H58]); 2.2 isolates were closely related following a single introduction around 2007, whereas H58 isolates had been introduced multiple times to the city. Increasing geographic distance between isolates was strongly associated with genetic clustering (odds ratio [OR] = 0.72 per km; 95% credible interval [CrI]: 0.66-0.79). This effect was seen for distances up to 5 km (OR = 0.65 per km; 95% CrI: 0.59-0.73) but not seen for distances beyond 5 km (OR = 1.02 per km; 95% CrI: 0.83-1.26). There was a non-significant reduction in odds of clustering for pairs of isolates in vaccination communities compared with non-vaccination communities or mixed pairs compared with non-vaccination communities. Our findings indicate that S . Typhi was repeatedly introduced into Navi Mumbai and then spread locally, with strong evidence of spatial genetic clustering. In addition to vaccination, local interventions to improve water and sanitation will be critical to interrupt transmission. IMPORTANCE Enteric fever remains a major public health concern in many low- and middle-income countries, as antimicrobial resistance (AMR) continues to emerge. Geographical patterns of typhoidal Salmonella spread, critical to monitoring AMR and planning interventions, are poorly understood. We performed whole-genome sequencing of S . Typhi and S . Paratyphi A isolates collected in Navi Mumbai, India before and after a typhoid conjugate vaccine introduction. From timed phylogenies, we found two dominant circulating lineages of S . Typhi in Navi Mumbai-lineage 2.2, which expanded following a single introduction a decade prior, and 4.3.1 (H58), which had been introduced repeatedly from other parts of India, frequently containing "triple mutations" conferring high-level ciprofloxacin resistance. Using Bayesian hierarchical statistical models, we found that spatial distance between cases was strongly associated with genetic clustering at a fine scale (<5 km). Together, these findings suggest that antimicrobial-resistant S . Typhi frequently flows between cities and then spreads highly locally, which may inform surveillance and prevention strategies., Competing Interests: The authors declare no conflict of interest.

Background: The World Health Organization recommends vaccines for prevention and control of typhoid fever, especially where antimicrobial-resistant typhoid circulates. In 2018, the Navi Mumbai Municipal Corporation (NMMC) implemented a typhoid conjugate vaccine (TCV) campaign. The campaign targeted all children aged 9 months through 14 years within NMMC boundaries (approximately 320 000 children) over 2 vaccination phases. The phase 1 campaign occurred from 14 July 2018 through 25 August 2018 (71% coverage, approximately 113 420 children). We evaluated the phase 1 campaign's programmatic effectiveness in reducing typhoid cases at the community level., Methods: We established prospective, blood culture-based surveillance at 6 hospitals in Navi Mumbai and offered blood cultures to children who presented with fever ≥3 days. We used a cluster-randomized (by administrative boundary) test-negative design to estimate the effectiveness of the vaccination campaign on pediatric typhoid cases. We matched test-positive, culture-confirmed typhoid cases with up to 3 test-negative, culture-negative controls by age and date of blood culture and assessed community vaccine campaign phase as an exposure using conditional logistic regression., Results: Between 1 September 2018 and 31 March 2021, we identified 81 typhoid cases and matched these with 238 controls. Cases were 0.44 times as likely to live in vaccine campaign communities (programmatic effectiveness, 56%; 95% confidence interval [CI], 25% to 74%; P = .002). Cases aged ≥5 years were 0.37 times as likely (95% CI, .19 to .70; P = .002) and cases during the first year of surveillance were 0.30 times as likely (95% CI, .14 to .64; P = .002) to live in vaccine campaign communities., Conclusions: Our findings support the use of TCV mass vaccination campaigns as effective population-based tools to combat typhoid fever., Competing Interests: Potential conflicts of interest.

Pediatric guidelines vary in their recommended amoxicillin dosing for common respiratory infections. It would help program delivery if there was harmonization of dosing and formulation of amoxicillin across multiple clinical respiratory infections, considering the pharmacokinetics, common targets, drug resistance, availability, cost effectiveness, and ease of administration. The World Health Organization EML AWaRe Book recommends higher dose amoxicillin given twice daily for five days for all uncomplicated respiratory infections where an antibiotic is indicated. The WHO AWaRe Book amoxicillin dosing guidance can be achieved for infants and older children using only scored 250 mg and 500 mg dispersible tablets (DTs), the WHO recommended child formulation. There is a clear need for wider availability of 250 mg/500 mg dispersible tablets of amoxicillin in both public and private health care sectors, to improve access to essential antibiotics.

Genetic variants of vaccine poliovirus type 2, imported from an unknown source, were detected in waste waters in Jerusalem, London and New York in early 2022. Wild poliovirus type 2 was globally eradicated in 1999, but vaccine virus type 2 continued for 16 more years; routine use of the vaccine was discontinued in 2016 and reintroduced occasionally on purpose. As an unintended consequence, type 2 vaccine virus variants (circulating vaccine-derived polioviruses, cVDPVs) that mimic wild viruses' contagiousness and neurovirulence, have been emerging and spreading. To illustrate, in just the past four years (2018-2021), 2296 children developed cVDPV polio in 35 low-income countries. Many assume that virus transmission is via the faecal-oral route. Sustained virus transmission was documented in London and New York, in spite of high standards of sanitation and hygiene. Here, virus transmission cannot be attributed to faecal contamination of food or drinking water (for faecal-oral transmission). Hence, contagious transmission can only be explained by inhalation of droplets/aerosol containing virus shed in pharyngeal fluids (respiratory transmission), as was the classical teaching of polio epidemiology. If transmission efficiency of VDPV is via the respiratory route where hygiene is good, it stands to reason that it is the same case in countries with poor hygiene, since poor hygiene cannot be a barrier against respiratory transmission. By extrapolation, the extreme transmission efficiency of wild polioviruses must also have been due to their ability to exploit respiratory route transmission. These lessons have implications for global polio eradication. It was as a result of assuming faecal-oral transmission that eradication was attempted with live attenuated oral polio vaccine (OPV), ignoring its safety problems and very low efficacy in low-income countries. Inactivated poliovirus vaccine (IPV) is completely safe and highly efficacious in protecting children against polio, with just three routine doses. Protecting all children from polio must be the interim goal of eradication, until poliovirus circulation dies out under sustained immunisation pressure. OPV should be discontinued under cover of immunity induced by IPV to stop the emergence of new lineages of VDPVs, not only type 2, but also types 1 and 3, to expedite the completion of polio eradication.

Rising antimicrobial resistance (AMR) is causing therapeutic failures with antibiotics. Inappropriate use is a contributing factor. One such antibiotic on the radar is faropenem, a broad spectrum antibiotic approved in 2005 in India. Recently, faropenem sodium suspension was approved for use in children. There is a potential danger of overuse due to the convenience of oral administration. Other carbapenems such as meropenem are used parenterally. Overuse of faropenem may promote cross-resistance with other carbapenems making them ineffective.

Earlier we, TJJ and DD, had written in IJME, that during the pandemic with high case-fatality in those above 65 and younger adults with chronic lung, heart or kidney diseases or diabetes, vaccination must be administered early as a life-saving procedure (1). It was pointed out that protection delayed may be protection denied to drive home the urgency of vaccination for saving lives. At that time, Phase III vaccine trials were in progress and we had adequate data on safety, but efficacy had yet to be measured. Good immunogenicity had already been documented in Phases I and II in which there were no signals of safety problems. Efficacy was "on promise" when we argued for early vaccination of those at risk of death.

The coronavirus disease 2019 (COVID-19) pandemic will transition into endemic phase with perpetual risk of severe disease and high mortality in vulnerable people - the elderly and those with co-morbidities, unless eradicated. Although several vaccines are already available to rich countries, low-income countries face gross vaccine inequity. We propose COVID-19 eradication to address both problems. An eradication program will ensure vaccine equity and international cooperation to establish public health surveillance and high quality laboratory diagnostic services in all countries. Eradication is biologically and technically feasible. We hope the World Health Organization will accept the proposition and design the necessary strategy without delay.

Preoperative extensive PV thrombosis can pose a technical challenge during liver transplantation surgery. Several strategies adopted to mitigate this problem include creation of a superior mesenteric vein-PV jump graft, use of a polytetrafluoroethylene graft, renoportal anastomosis, or cavoportal hemitransposition. Extensive and diffuse thrombosis of the splanchnic venous system may even necessitate multivisceral transplantation. We describe the case of a pediatric patient with Budd-Chiari syndrome and decompensated cirrhosis, who developed extensive thrombosis of the porto-spleno-mesenteric venous system prior to liver transplantation. We used a combination technique of thrombus aspiration by a novel trans-TIPPS approach followed by thrombolysis. Complete preoperative resolution of the extensive thrombosis was achieved. This allowed the creation of a brief window to enable planned LDLT. In prudently selected patients, performing an early mechanical and chemical thrombolysis of an extensive acute splanchnic venous thrombosis can thus help expedite a planned LDLT., (© 2020 Wiley Periodicals LLC.)

Background: While there have been studies in adults reporting discordant empiric antibiotic treatment associated with poor outcomes, this area is relatively unexplored in children and neonates despite evidence of increasing resistance to recommended first-line treatment regimens., Methods: Patient characteristics, antibiotic treatment, microbiology, and 30-day all-cause outcome from children <18 years with blood-culture-confirmed bacterial bloodstream infections (BSI) were collected anonymously using REDCap™ through the Global Antibiotic Prescribing and Resistance in Neonates and Children network from February 2016 to February 2017. Concordance of early empiric antibiotic treatment was determined using European Committee on Antimicrobial Susceptibility Testing interpretive guidelines. The relationship between concordance of empiric regimen and 30-day mortality was investigated using multivariable regression., Results: Four hundred fifty-two children with blood-culture-positive BSI receiving early empiric antibiotics were reported by 25 hospitals in 19 countries. Sixty percent (273/452) were under the age of 2 years. S. aureus, E. coli, and Klebsiella spp. were the most common isolates, and there were 158 unique empiric regimens prescribed. Fifteen percent (69/452) of patients received a discordant regimen, and 7.7% (35/452) died. Six percent (23/383) of patients with concordant regimen died compared with 17.4% (12/69) of patients with discordant regimen. Adjusting for age, sex, presence of comorbidity, unit type, hospital-acquired infections, and Gram stain, the odds of 30-day mortality were 2.9 (95% confidence interval: 1.2-7.0; P = 0.015) for patients receiving discordant early empiric antibiotics., Conclusions: Odds of mortality in confirmed pediatric BSI are nearly 3-fold higher for patients receiving a discordant early empiric antibiotic regimen. The impact of improved concordance of early empiric treatment on mortality, particularly in critically ill patients, needs further evaluation., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2020 Wolters Kluwer Health, Inc.

The Covid-19 pandemic is raging, taking heavy toll of lives and livelihoods. The need for safe and effective vaccine(s) is urgent. Vaccine research has progressed rapidly and a few vaccine candidates have passed trial Phases 1 and 2, confirming reasonable safety and immunogenicity parameters. They are ready for large scale Phase 3 trials to quantify protective efficacy, if any, and to detect uncommon but serious adverse effects, if any. These developments present unprecedented opportunities and challenges, scientific and ethical. Globally hundreds die every day due to Covid-19, and emergency/compassionate use of vaccine candidates that are ready for Phase 3 trials are likely to save lives. We perceive an ethical imperative to allow such vaccination for those at high risk of death and voluntarily make such informed choice - for them protection delayed will be tantamount to protection denied.

Influenza continues to baffle humans by its constantly changing nature. The twenty-first century has witnessed considerable advances in the understanding of the influenza viral pathogenesis, its synergy with bacterial infections and diagnostic methods. However, challenges continue: to find a less expensive and more reliable point-of-care test for use in developing countries, to produce more efficacious antiviral drugs, to explore ways to combat emerging antiviral resistance and to develop vaccines that can either be produced in a shorter production time or can overcome the need for annual matching with the circulating influenza strains. Most importantly for India, as a nation that suffered the highest mortality in the influenza pandemic 1918, there is an urgent need to gear up our existing preparedness for the next pandemic which is capable to hit at any moment in time.

An outbreak of Hand, Foot and Mouth Disease (HFMD) was reported in Navi Mumbai in July-October 2018. Of 15 HFMD cases, two had recurrences within a month while three had lesions extending to trunk. Coxsackie virus A6 and A16 were detected from 13 cases (CV-A6 from 10 cases and CV-A16 from 3 cases) indicating co-circulation of these viruses. The present study highlights an urgent need of HFMD surveillance.

During the last five years, globally, cases of polio caused by vaccine viruses have outnumbered those of polio caused by natural (wild) polioviruses, posing a moral dilemma. Public health ethics should ensure the best interests of the community, with equity in sharing benefits and risks irrespective of socioeconomic disparities. Vaccine viruses in oral polio vaccine (OPV) cause vaccine-associated paralytic polio (VAPP), while paralytic polio is also caused by vaccine-derived polioviruses (VDPVs). By its policy of the use of OPV in low and middle-income countries, while rich countries use the safe inactivated polio vaccine (IPV), the Global Polio Eradication Programme has been responsible for social injustice. In 2017 and 2018, there were outbreaks of polio in Syria and Papua New Guinea due to circulating VDPVs, after many years of these countries remaining free of polio due to wild polioviruses. The only ethical way forward for global polio eradication is to replace OPV with IPV in all countries.

Medical ethics is invoked for immunisation of children as it involves an interaction between a healthcare professional and the child. Immunisation under the national immunisation programme is a public health intervention and the common belief is that ethics is not relevant. Two vaccines with contrasting safety and efficacy profiles were available against polio before the national immunisation programme was launched: the inactivated poliovirus vaccine (IPV) and the live attenuated oral poliovirus vaccine (OPV). India chose OPV and excluded IPV. We carried out an ethical appraisal of that choice. Principles of medical ethics comprising four elements-non-maleficence, beneficence, autonomy and justice-was already in vogue at the time. Applying each of them, a head-to-head comparison between IPV and OPV is made. The results clearly show that the choice of vaccine was made without using ethical principles, resulting in serious adverse effects in hundreds of thousands of children. We recommend that medical ethics must be applied to all choices of public health interventions.

Background: Information about antimicrobial use is scarce and poorly understood among neonatal intensive care units (NICUs) in India. In this study, we describe antimicrobial use in eight NICUs using four point prevalence surveys (PPSs)., Methods: As part of the Global Antimicrobial Resistance, Prescribing, and Efficacy in Neonates and Children (GARPEC) study, one-day, cross-sectional, hospital-based PPSs were conducted four times between 1 February 2016 and 28 February 2017 in eight NICUs. Using a standardized web-based electronic data entry form, detailed data were collected for babies on antimicrobials., Results: A total of 403 babies were admitted to NICUs across all survey days, and 208 (51.6%) were prescribed one or more antimicrobials. Among 208 babies, 155 (74.5%) were prescribed antimicrobials for treatment of an active infection. Among 155 babies with an active infection, treatment was empiric in 109 (70.3%). Sepsis (108, 49.1%) was the most common reason for prescribing antimicrobials. Amikacin (17%) followed by meropenem (12%) were the two most commonly prescribed antimicrobials. For community-acquired sepsis, piperacillin-tazobactam (17.5%) was the most commonly prescribed drug. A combination of ampicillin and gentamicin was prescribed in only two babies (5%)., Conclusions: The recommended first-line antimicrobial agents, ampicillin and gentamicin, were rarely prescribed in Indian NICUs for community acquired neonatal sepsis., (Copyright © 2018 The Author(s).

Streptococcus pyogenes , belonging to group A streptococcus (GAS), causes over 600 million infections annually being a predominant human pathogen. Lack of genomic data on GAS from India is one limitation to understand its virulence and antimicrobial resistance determinants. The genome of GAS isolates from clinical samples collected at Navi Mumbai, India was sequenced and annotated. Sequencing was performed on Ion Torrent PGM platform. The size of annotated S. pyogenes genomes ranged from ~1.69 to ~1.85 Mb with coverage of 38× to 189×. Most of the isolates had msr(D) and mef(A) , and four isolates had erm(B) gene for macrolide resistance. The genome harboured multiple virulence factors including exotoxins in addition to phage elements in all GAS genomes. Four isolates belonged to sequence type ST28, 7 were identified as ST36 and 1 as ST55.

The prevalence of antimicrobial resistance in India is among the highest in the world. Antimicrobial use in inpatient settings is an important driver of resistance, but is poorly characterized, particularly in hospitalized children. In this study, conducted as part of the Global Antimicrobial Resistance, Prescribing, and Efficacy in Neonates and Children (GARPEC) project, we examined the prevalence of and indications of antimicrobial use, as well as antimicrobial agents used among hospitalized children by conducting four point prevalence surveys in six hospitals between February 2016 and February 2017. A total of 681 children were hospitalized in six hospitals across all survey days, and 419 (61.5%) were prescribed one or more antimicrobials (antibacterials, antivirals, antifungals). Antibacterial agents accounted for 90.8% (547/602) of the total antimicrobial prescriptions, of which third-generation cephalosporins (3GCs) accounted for 38.9% (213/547) and penicillin plus enzyme inhibitor combinations accounted for 14.4% (79/547). Lower respiratory tract infection (LRTI) was the most common indication for prescribing antimicrobials (149 prescriptions; 24.8%). Although national guidelines recommend the use of penicillin and combinations as first-line agents for LRTI, 3GCs were the most commonly prescribed antibacterial agents (55/149 LRTI prescriptions; 36.9%). In conclusion, 61.5% of hospitalized children were on at least one antimicrobial agent, with excessive use of 3GCs. Hence there is an opportunity to limit their inappropriate use., Competing Interests: The authors declare no conflict of interest. The funding sponsors had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript, and in the decision to publish the results.

Background: There is real shortage of national data on antimicrobial resistance rates in Indian neonates and children. A descriptive review was conducted to determine the patterns of antimicrobial resistance in isolates of blood stream infection among hospitalized children in India., Methods: Published and gray literature on antibiotic resistance in children was searched using "Google Scholar", "Scopus", and "PubMed" databases between January 2000 and July 2015. Studies were included if they were original articles that reported a minimum of 10 pathogenic bacterial isolates from the bloodstream within a pediatric population in India, and studies were excluded if they reported studies done during an outbreak or epidemic., Results: A total of 1179 studies were screened, and 82 papers were identified as eligible for inclusion. Most studies (78.7%) were reported from neonatal intensive care units. Among a total of 50545 reported blood cultures, 14704 (29.1%) were positive. Staphylococcus aureus (median, 14.7%; IQR, 7.4%-25.6%) and Klebsiella pneumoniae (median, 26%; IQR, 16.7%-35.4%) were the commonest reported Gram-positive and Gram-negative pathogens, respectively. Approximately half of all S aureus isolates were reported as methicillin-resistant S aureus (median, 50%; IQR, 31.4%-65.1%). After age stratification, the median rate of resistance of common Gram-negative pathogens to ampicillin and gentamicin/amikacin were extremely high (K pneumoniae/ampicillin 95.9%; K pneumoniae/gentamicin 75%; Escherichia coli/ampicillin 92.9%; E coli/gentamicin 55.6%). Likewise, the median resistance of common Gram-negative blood stream isolates to cephalosporins were also high (K pneumoniae/cefotaxime 62.6%; E coli/cefotaxime 47.5%)., Conclusions: High rates of resistance to World Health Organization-recommended first-line treatment options for neonates and children have been identified in blood stream infections across India. There is an urgent need to both enhance antibiotic stewardship and infection prevention and control measures and consider urgently how to repurpose older antibiotics back into routine care in India., (© The Author 2017.

Introduction: Antibiotic resistance is a topic of global concern these days. Irrational, excessive use of antibiotics by the general public is one of the key factors responsible for this., Aim: Through this study, we aim to analyse the knowledge, attitude and practices of antibiotics use among parents of children presenting to a tertiary care hospital in India. Also, correlate it with the gender, education level and previous use of antibiotics by the parents., Materials and Methods: A cross sectional study was conducted at a tertiary care hospital in Navi Mumbai, India from September to November 2014 and a total of 1000 parents were interviewed using a questionnaire designed by the authors. Descriptive statistics were used for the analysis of data., Results: A total of 872 parents were included in the study. Around one in every four (28%) parents correctly identified that antibiotics are used against bacterial infections while only 15.5% parents knew the meaning of the term antibiotic resistance. Majority of the respondents appreciated that unnecessary use of antibiotics could harm the child (73.6%). It was noteworthy that 85.2% parents stated that they don't use leftover antibiotics from the previous prescription for the next time without doctor's consult. Males, parents with higher level of formal education and use of antibiotics previously were found to have more knowledge regarding antibiotics and lesser misconceptions (p<0.05)., Conclusion: Overall, in this study it was found that misconceptions exist about the use and indications of antibiotics. Lack of knowledge regarding antibiotic resistance was prevalent. But participants were aware of the risks associated with use of excessive antibiotics. More interaction with paediatricians and involvement of mass media may help to improve the antibiotics knowledge and practices among parents and consequently, control the problem of antibiotic resistance.

Promotion of appropriate and safe drugs in children is the need of the hour globally. Pediatric population by itself is a spectrum of different physiologies with significant variation in pharmacodynamics and pharmacokinetics. Unfortunately, 50-90% of drugs used in children today have never been actually studied in this population, and the results of drug studies done in adults are often extrapolated for use in children. Many medicines in pediatrics are off label or unlicensed. There is a spurt in drug resistance due to the overzealous prescription of antimicrobials not indicated, such as, using inadequate dosage or duration of drug regime leading to partially treated infections, using the wrong antimicrobial due to ignorance of causative organism, and finally using indigenous, irrational combinations. Availability of properly labeled and safe pediatric formulations, regular audit by pharmacists, judicious prescriptions, proper counseling about drug administration, surveillance of adverse effects, and pediatric drug trials can be the best possible interventions to offer appropriate medicines to children and thereby save millions of lives.
