A lyophilized bovine-human rotavirus reassortant pentavalent vaccine (BRV-PV, Rotasiil®) was licensed in 2016. A liquid formulation of this vaccine (LBRV-PV, Rotasiil - Liquid) was subsequently developed and was tested for non-inferiority to Rotasiil® and for lot-to-lot consistency.This Phase II/III, open label, randomized study was conducted at seven sites across India from November 2017 to June 2018. Participants were randomized into four arms; Lots A, B, and C of LBRV-PV and Rotasiil® in 1:1:1:1 ratio. Three doses of study vaccines were given at 6, 10, and 14 weeks of age. Blood samples were collected four weeks after the third dose to assess rotavirus IgA antibody levels. Non-inferiority of LBRV-PV to Rotasiil was proven if the lower limit two-sided 95% confidence interval (CI) of geometric mean concentration (GMC) ratio was at least 0.5. Lot-to-lot consistency was proven if 95% CI of the GMC ratios of three lots were between 0.5 and 2. Solicited reactions were collected by using diary cards.Of the 1500 randomized infants, 1436 infants completed the study. The IgA GMC ratio of LBRV-PV to Rotasiil® was 1.19 (95% CI 0.96, 1.48). The corresponding IgA seropositivity rates were 60.41% (57.41, 63.35) and 52.75% (47.48, 57.97). The IgA GMC ratios among the three LBRV-PV lots were: Lot A versus Lot B: 1.34 (1.03, 1.75); Lot A versus Lot C: 1.22 (0.93, 1.60); and Lot B versus Lot C: 0.91 (0.69, 1.19). The 95% CIs for the GMC ratios were between 0.69 and 1.75. The incidence of solicited reactions was comparable across the four arms. Only one serious adverse event of gastroenteritis event in the Rotasiil® group was causally related.The immunological non-inferiority of LBRV-PV against Rotasiil® as well as lot-to-lot consistency of LBRV-PV was demonstrated. LBRV-PV had safety profile similar to Rotasiil®.Clinical Trials.Gov [NCT03474055] and Clinical Trial Registry of India [CTRI/2017/10/010104].

Objective Vitamin B12 is not synthesized in the body and its only dietary sources are non-vegetarian. The breast milk of mothers in resource poor countries who are on predominantly vegetarian diets is deficient in vitamin B12. Hence exclusive breast feeding (EBF) may result in B12 deficiency in the infant, which can affect the neurodevelopmental outcome. Our aim was to study the serum vitamin B12 levels among EBF infants and identify the risk factors for B12 deficiency. Method This cross-sectional study was done among EBF, term, otherwise healthy infants, 1–6 month of age in the well-baby clinic .The sociodemographic data of mother and the infants’ anthropometric measurements were noted and blood samples were sent for complete blood count and serum vitamin B12 levels. The data were analysed using SPSS software version 16. Results We enrolled 149 EBF infants, aged 1–6 months and the mean age was 3.1 (±1.03) months. The mean serum vitamin B12 level was 199.91 (±112.523) pg/ml. Low serum vitamin B12 levels ( Conclusion The prevalence of vitamin B12 deficiency among EBF infants is 63.7%. Because of its importance in neurological development during infancy, there is an urgent need to address this issue while promoting exclusive breast feeding.

This retrospective study was done to compare the nutrition status as assessed by the Revised IAP 2015 and CDC 2000 growth charts in 4011 school children from the lower socioeconomic class, 5 to 16 y of age in Chennai, Tamil Nadu. The anthropometric measurements taken as per standard guidelines were retrieved from the school health records. The data were converted to Z scores and agreement between the two charts was assessed by kappa coefficient using SPSS version 16. The prevalence of overweight/obesity, thinness and stunting was 12.2%, 9.8% and 9% respectively with IAP 2015 charts. The corresponding values are 7.3%, 41.7% and 23% respectively with CDC 2000 charts. Minimal agreement was found for body mass index (BMI) for age (kappa 0.314) and weak agreement for height for age (kappa 0.497). Revised IAP 2015 growth charts diagnose more Indian children with overweight and obesity than CDC 2000 growth charts. The CDC growth chart diagnoses more stunting and thinness.

A newly developed bovine-human reassortant pentavalent vaccine (BRV-PV, ROTASIIL®) was tested for its potential effect on the immunogenicity of concomitantly administered EPI vaccines in infants in a randomized controlled study in India.In this Phase III, multicenter, open label, randomized, controlled study, three doses of BRV-PV or two doses of Rotarix® and one dose of placebo were given to healthy infants at 6, 10, and 14 weeks of age. Subjects also received three doses of DTwP-HepB-Hib (diphtheria, tetanus, whole-cell pertussis, hepatitis B, and haemophilus influenzae type b conjugate - pentavalent vaccine) and oral polio vaccine concomitantly at 6, 10, and 14 weeks of age and a single dose of inactivated polio vaccine at 14 weeks of age. Blood samples were collected four weeks after the final vaccination to assess immune responses to all the vaccines administered. For diphtheria, tetanus, hepatitis B, Hib, polio type 1, and polio type 3 antibodies, non-interference was to be supported if the lower limit of the two-sided 90% confidence interval (CI) for the seroprotection rate difference for the BRV-PV group minus the Rotarix® group was10.0%. For pertussis antibodies, non-interference was to be supported if the lower limit of the two-sided 90% CI for the ratio of geometric mean concentrations (GMCs) was0.5.A total of 1500 infants were randomized to either BRV-PV (1125 infants) or Rotarix® (375 infants), of which 1341 completed the study as per the protocol. More than 97% of subjects achieved seroprotective antibody titres against diphtheria, tetanus, hepatitis B, Hib, polio type 1, and polio type 3 in both groups. The difference in seroprotection rates between the BRV-PV group and the Rotarix® group for all these antibodies was less than 1%. The ratio of GMCs of anti-pertussis IgG concentrations for the BRV-PV group versus Rotarix® was 1.04 [90% CI: 0.90; 1.19].BRV-PV does not interfere with the immunogenicity of concomitantly administered routine infants vaccines.

Background: Cleft lip and palate is one of the most frequent birth defects and is associated co-morbidities such as facial abnormalities, difficulty in feeding, speech impairments and hearing difficulties. The psychological consequences of this anomaly are often not addressed effectively resulting in silent suffering for these individuals. The dissatisfaction with surgical outcome as well as the stigma and discrimination may affect the quality of life for both patients and their family. The study evaluates the self-perceived quality of life in children with repaired cleft lip/palate . Methods: Adolescents between the age of 11-18 years who were operated for cleft lip and palate in their early years were administered the WHO QOL-BREF questionnaire and their response were analysed in 4 domains, Physical health, Psychological, Social relationship and environmental. Results: Among the 46 children enrolled, 29 were boys and 17girls. The mean scores across each domain were as follows: Physical health-68.5, psychological-66, social relationship-88.5 and environmental-79.1. The psychological stressors frequently encountered were: teasing by their peer group, unattractive physical appearance and dissatisfaction with facial features post-surgery . Conclusions: Among the 4 domains, the mean value of domain 3 (Social relationship) was the highest-88.5 and the mean value of domain 2 (Psychosocial) is the lowest-66. Continued psychological counselling and support during the turbulent adolescent years will help these children face the challenge of integrating with the society.
