Invasive pneumococcal disease in children aged younger than 5 years in India: a surveillance study.

BACKGROUND: Invasive pneumococcal disease continues to be a major cause of morbidity and mortality among children younger than 5 years of age in India. We aimed to provide nationally representative data for the pattern of disease due to Streptococcus pneumoniae, trends in the serotype of invasive pneumococci, and invasive pneumococci antimicrobial resistance patterns, in India. METHODS: In this prospective hospital-based and retrospective laboratory-based surveillance study, we prospectively enrolled children aged younger than 5 years with suspected or proven invasive pneumococcal disease from 18 hospitals or institutional centres and retrospectively included laboratory-confirmed pneumococcal isolates from ten sentinel laboratories, together representing 11 states in India. Eligibility criteria were fever higher than 38°C without localising symptoms, clinical presentation of suspected meningitis or pneumonia, and evidence of radiographic pneumonia. We cultured blood and other normally sterile body fluids, reconfirmed and serotyped pneumococcal isolates, and established antimicrobial susceptibility using standard study protocols. FINDINGS: Between Jan 1, 2011, and June 30, 2015, we enrolled 4377 patients. Among 361 (8%) patients with culture-proven pneumococcal disease, all clinical data were known for 226 (63%); among these patients, 132 (58%) presented with pneumonia, 78 (35%) presented with meningitis, and 16 (7%) had other clinical conditions. 131 (3%) died overall and 29 (8%) patients with invasive pneumococcal disease died. Serotypes 14 (52 [14%] of 361), 1 (49 [14%]), 5 (37 [10%]), and 19F (33 [9%]) were the most common. Penicillin non-susceptibility occurred in isolates from 29 (8%) patients, co-trimoxazole resistance occurred in 239 (66%), erythromycin resistance occurred in 132 (37%), and chloramphenicol resistance occurred in 33 (9%). We found multidrug resistance in 33 (9%) of 361 patients. INTERPRETATION: The proportion of positive blood cultures, number of isolates, geographical representation, and data generated over the 4·5 years of the study are representative of data for most of India. Continued surveillance is warranted as the decision to introduce protein conjugated vaccine in India is made. FUNDING: GlaxoSmithKline India.

Global Polio Eradication,The Journey So Far.

The Global Polio Eradication Initiative (GPE I), since its launch in 1988 has achieved more than 99% reduction in polio cases globally, using oral polio vaccine (OPV). Currently only two countries (Pakistan and Afghanistan) have not been able to stop transmission of wild poliovirus (wPV). In this article, we discuss some of the challenges faced by these two countries. The lessons learnt from the tremendous public health success stories of India and Nigeria are also highlighted. Reintroduction of wPV in the polio-free areas remains a valid risk globally and some recent examples are discussed. Inactivated polio vaccine (IPV) is the most accepted risk-mitigation strategy to secure a polio-free world from both wPV and circulating vaccine derived poliomyelitis (VDPV). The challenges related to switch from trivalent to bivalent OPV and introduction of IPV in 156 countries using trivalent OPV, are also highlighted.

Antibiotics Use and Misuse in Children: A Knowledge, Attitude and Practice Survey of Parents in India.

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.

IAP Position Paper on Burden of Mumps in India and Vaccination Strategies.

JUSTIFICATION: Mumps, despite being a widely prevalent disease in the country, is considered as an insignificant public health problem mainly because of poor documentation of clinical cases and lack of published studies. In the absence of adequate published data on disease burden, Government of India has recently decided to introduce measles-rubella (MR) vaccine in its National Immunization Program and neglected mumps component. PROCESS: Following an IAP ACVIP meeting on December 6 and 7, 2014, a detailed review of burden of mumps in India along with vaccination strategies to control the disease was prepared. The draft was circulated amongst the members of the committee for review and approval. Revised final draft was later approved by IAP executive board in January 2015. OBJECTIVES: To provide a review of community burden of mumps in India; and to discuss the vaccination strategies to impress upon policymakers to include mumps vaccination in National immunization program. RECOMMENDATIONS: A total of 14 studies and two media reports on mumps outbreak were retrieved. The outbreaks were reported from all the regions of the country. Mumps meningoencephalitis was responsible for 2.3% to 14.6% of all investigated hospitalized acute encephalitis syndrome or viral encephalitis cases in different studies. Data from Infectious Disease Surveillance (ID Surv) portal of IAP and Integrated Disease Surveillance Program (IDSP) of Government of India (GoI) were also reviewed. While a total of 1052 cases were reported by the IDSurv, IDSP had investigated 72 outbreaks with 1564 cases in 14 states during different time periods. Genotypes G (subtype G2) and C were found to be main genotypes of the mumps virus circulating in the country. Three studies studied serological status of young children and adolescents against mumps, and found susceptibility rates ranging from 32% to 80% in different age groups. CONCLUSIONS: Mumps poses a significant disease burden in India. This calls for inclusion of mumps vaccine in the National immunization program.

Indian Academy of Pediatrics (IAP) recommended immunization schedule for children aged 0 through 18 years--India, 2014 and updates on immunization.

JUSTIFICATION: There is a need to review/revise recommendations about existing vaccines in light of recent developments in the field of vaccinology. PROCESS: Following an IAP ACVIP meeting on April 19 and 20, 2014, a draft of revised recommendations for the year 2014 and updates on certain vaccine formulations was prepared and circulated among the meeting participants to arrive at a consensus. OBJECTIVES: To review and revise recommendations for 2014 Immunization timetable for pediatricians in office practice and issue statements on certain new and existing vaccine formulations. RECOMMENDATIONS: The major changes in the 2014 Immunization Timetable include two doses of MMR vaccine at 9 and 15 months of age, single dose recommendation for administration of live attenuated H2 strain hepatitis A vaccine, inclusion of two new situations in high-risk category of children in context with pre-exposure prophylaxis of rabies, creation of a new slot at 9-12 months of age for typhoid conjugate vaccine for primary immunization, and recommendation of two doses of human papilloma virus vaccines with a minimum interval of 6 months between doses for primary schedule of adolescent/preadolescent girls aged 9-14 years. There would not be any change to the committee's last year's (2013) recommendations on pertussis vaccination and administration schedule of monovalent human rotavirus vaccine. There is no need of providing additional doses of whole-cell pertussis vaccine to children who have earlier completed their primary schedule with acellular pertussis vaccine-containing products. A brief update on the new Indian Rotavirus vaccine, 116E is also provided. The committee has reviewed and offered its recommendations on the currently available pentavalent vaccine (DTwP+Hib+Hepatitis-B) combinations in Indian market. The comments and footnotes for several vaccines are also updated and revised.

IAP perspectives on measles and rubella elimination strategies.

The Academy's Expert group on Immunization has discussed various issues pertaining to rubella vaccine introduction in to the Universal Immunization Program. Though the move to introduce rubella vaccine in to the UIP is laudable, the decision to overlook mumps seems inexplicable and illogical. Logistics also support the use of measles-mump and rubella (MMR) vaccine instead of measles-rubella (MR) vaccine. Regarding the timing of administration of MMR/MR vaccine, the academy recommends that the vaccine should be given early to have much higher coverage than introducing it late at the time of 1st booster of DPT. According to available evidence, both these vaccines (MMR/MR) can be given safely at different ages including at 9 months of age. The second dose should also be of the same antigen (MMR/MR) and be given along with 1st DPT booster at 16-24 months of age.

Treatment of iron deficiency anemia in children: a comparative study of ferrous ascorbate and colloidal iron.

OBJECTIVE: To compare the efficacy of ferrous ascorbate and colloidal iron in the treatment of iron deficiency anemia in children. METHODS: Eighty one children, aged 6 mo to 12 y, were screened for iron deficiency anemia (IDA) and those diagnosed with IDA were randomized to receive ferrous ascorbate or colloidal iron for a period of 12 wk, such that each child received elemental iron 3 mg/kg body weight/d. Increase in hemoglobin (Hb) level was the primary outcome measure. Assessment was performed at baseline, wk 4, wk 8 and wk 12. RESULTS: Of 81 children screened, 73 were included in the study. The mean rise in Hb at the end of the 12 wk was significantly higher in ferrous ascorbate group than the colloidal iron group [3.59 ± 1.67 g/dl vs. 2.43 ± 1.73 g/dl; P < 0.01]. Significantly higher proportion of children receiving ferrous ascorbate (64.86 % vs. 31.03 %; P < 0.01) became non-anemic in comparison to colloidal iron. CONCLUSIONS: Ferrous ascorbate provides a significantly higher rise in hemoglobin levels in comparison to colloidal iron. The study supports the use of ferrous ascorbate in the pediatric age group, providing evidence for its role as an efficient oral iron supplement in the treatment of iron deficiency anemia.

Indian Academy of Pediatrics (IAP) recommended immunization schedule for children aged 0 through 18 years, India, 2013 and updates on immunization.

JUSTIFICATION: There is a need to review/revise recommendations about existing vaccines in light of recent developments in the field of vaccinology where new developments are taking place regularly at short intervals. PROCESS: Following an IAP ACVIP meeting on 3rd and 4th August, 2013, a draft of revised recommendations for the year 2013 and updates on certain new vaccine formulations was prepared and circulated among the meeting participants to arrive at a consensus. OBJECTIVES: To review and revise recommendations for 2013 Immunization timetable for pediatricians in office practice and issue statements on new vaccine formulations. RECOMMENDATIONS: The major change in the 2013 Immunization timetable was made in the recommendations pertaining to pertussis immunization. Taking in to the consideration of recent outbreaks of pertussis in many industrialized countries using acellular pertussis (aP) vaccines and subsequent finding of faster waning of the same in comparison to whole-cell pertussis (wP) vaccines and superior priming with wP vaccines than aP vaccines, the committee has now recommended wP vaccines for the primary series of infant vaccination. Guidelines are now also issued on the preference/selection of a particular aP vaccine in case it is not feasible to use wP vaccine, and use of Tdap vaccine during pregnancy. The administration schedule of monovalent human rotavirus vaccine, RV1 has been revised to 10 and 14 weeks from existing 6 and 10 weeks. Recommendation is made for the need of booster dose of live attenuated SA-14-14-2 JE vaccine. Updates and recommendations are issued on new typhoid conjugate vaccine, inactivated vero-cell culture derived SA-14-14-2 JE vaccine, inactivated vero-cell derived Kolar strain, 821564XY JE vaccine, and new meningococcal conjugate vaccines. This year the recommended immunization schedule with range for persons aged 0 through 18 years is being published together instead of two separate schedules. A subcategory of general instruction is added in footnotes. The comments and footnotes for several vaccines are revised and separate instructions for routine vaccination and catch-up vaccination are added in the footnotes section wherever applicable.

Promoting appropriate use of drugs in children.

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.
