Effectiveness of 3-Day Amoxycillin vs. 5-Day Co-trimoxazole in the Treatment of Non-severe Pneumonia in Children Aged 2-59 Months of Age: A Multi-centric Open Labeled Trial

This cluster randomized, open labeled trial was conducted to compare the effectiveness of 3 days of oral amoxycillin and 5 days of co-trimoxazole treatment in terms of clinical failure in children with World Health Organization (WHO) defined non-severe pneumonia in primary health centers in rural India. Participants were children aged 2-59 months with WHO defined non-severe pneumonia, with or without wheeze, who were accessible to follow up. From seven primary health centers in each arm, 2009 cases were randomized, 993 and 1016 in treatment with amoxycillin and co-trimoxazole, respectively. Fever was present in 1247 (62.1%) and wheeze in 443 (22.1%). There was good adherence and low loss to follow-up. Clinical failure on amoxycillin and co-trimoxazole on intention to treat analysis was 137 and 97, respectively (absolute difference = 0.04, 95% confidence interval: - 0.035-0.12). We conclude that there was no difference in effectiveness of oral co-trimoxazole or amoxycillin in treating non-severe pneumonia.

Effectiveness of Indigenous Ready-to-Use Therapeutic Food in Community-based Management of Uncomplicated Severe Acute Malnutrition: a Randomized Controlled Trial from India

A randomized controlled trial was conducted in Chandigarh, India (2011), to determine the effectiveness of indigenous ready-to-use therapeutic food (RUTF) in community-based management of uncomplicated severe acute malnutrition (SAM). Intervention was through outpatient therapeutic program site (OTP). Study and control group children (6 months-5 years) were followed up weekly for 12 weeks, in OTP and at home. All children received supplementary nutrition through anganwadis under integrated child development scheme. Study children, in addition, received therapeutic dose of RUTF in OTP. Primary outcome, 115% of baseline weight, was attained in 6 of 13 (46.2%) and 1 of 13 (7.7%) children among study and control group, respectively [odds ratio: 10.28, 95% confidence interval (CI): 1.02-103.95]. Compared with control group, addition of RUTF in study group resulted in average additional increase in weight by 13 g/kg of baseline weight/week/child (95% CI: 2-23). Indigenous RUTF was effective in community-based management of uncomplicated SAM.

Burden of invasive pneumococcal disease in children aged 1 month to 12 years living in South Asia: a systematic review.

Objective The primary objective was to estimate the burden of invasive pneumococcal disease (IPD) in children aged 1 month to 12 years in South Asian countries. Methods We searched three electronic databases (PubMed, Embase and the Cochrane Library) using a comprehensive search strategy, we manually searched published databases (Index Medicus and Current Contents) and we also searched the bibliographies of the included studies and retrieved reviews. The searches were current through June 2013. Eligible studies (community-based and hospital-based) were pooled and a separate analysis for India was also completed. A meta-regression analysis and heterogeneity analysis were performed. The protocol was registered with PROSPERO registration number CRD42013004483. Results A total of 22 studies surveying 36,714 children were included in the systematic review. Hospital-based prospective studies from South Asia showed that 3.57% of children had IPD, and 15% of all bacterial pneumonia cases were due to Streptococcus pneumoniae. Indian studies showed that the incidence of IPD was 10.58% in children admitted to hospitals with suspected invasive bacterial diseases, and 24% of all bacterial pneumonia cases were due to S. pneumonia. Population-based studies from South Asian countries showed that 12.8% of confirmed invasive bacterial diseases were caused by S. pneumonia whereas retrospective hospital-based studies showed that 28% of invasive bacterial diseases were due to S. pneumoniae. Meta-regression showed that there was a significant influence of the antigen testing method for diagnosing IPD on IPD prevalence. Conclusion S. pneumoniae is responsible for a substantial bacterial disease burden in children of South Asian countries including India despite the presence of high heterogeneity in this meta-analysis. Treatment guidelines must be formulated, and preventive measures like vaccines must also be considered.

Prevalence and Treatment Gap in Childhood Epilepsy in a North Indian City: A Community-Based Study

BACKGROUND Epilepsy is one of the most common neurological disorders prevalent in childhood period. There is scarcity of epidemiological data, required to plan services in resource constrained developing nations. OBJECTIVE To study the prevalence and treatment gap in childhood epilepsy in north Indian city, in the age group of 1-18 years. METHODS A two stage stratified cluster sampling; probability proportionate to size (PPS) was employed. A ten question screening questionnaire was employed to identify the presence of epilepsy. Definitions provided by International League against Epilepsy (ILAE) were used to classify screen positive subjects as epilepsy and to calculate the treatment gap. RESULTS The prevalence rate for epilepsy was 6.24/1000 population. Febrile seizures and neurocysticercosis were most common causes of symptomatic seizures in childhood. CONCLUSION This study of epidemiology of epilepsy provides valuable aid in optimizing effective community approach, thereby improving outcomes of childhood epilepsy.

Association of fungal sepsis and galactosemia

Galactosemia is one of the rare inborn errors of metabolism, which if detected early can be treated effectively. Galactosemic infants have a significant increased risk of developing sepsis. E. coli sepsis is a known entity, and also an important cause of early mortality in these children. But fungal sepsis in these patients is rarely reported. Here is a case of 45 day-old child who presented with fungal sepsis, which on investigation turned out to be galactosemia.

Measles in a hilly hamlet of northern India

Objective : To ascertain the epidemiological links and risk factors responsible for the epidemic of measles in the village Astani in Himachal Pradesh.Methods : All the children less than twelve years who were present on 27th July 1997 were evaluated. A questionnaire requesting data on vaccination history and symptoms of measles was administered and complete physical examination including anthropometry was recorded in each child by the authors. The data also included complications (including that of death) secondary to measles infection.Results : A total of 48 children less than 12 years, present in the hamlet on 27th July 1997, were examined, out of which 28 (58%) were affected and 20 (42%) were unaffected. The immunization coverage in the affected children was 33% in contrast to 70% coverage in the unaffected group. Vaccine efficacy in the present epidemic was 51 %. The complication rate was 59%, which included one death. The anthropometric data showed that 92% of the affected children were malnourished. All the children were given age appropriate dose of Vitamin A and children of the nearby villages were vaccinated against measles as a part of outbreak control.Conclusion : This study clearly highlights the need to achieve and sustain high immunization coverage along with strengthening of the routine surveillance systems in remote village of India.

Vaccine Related Reactogenicity for Primary Immunization: A Randomized Controlled Trial of 23(Wider) vs. 25(Narrower) Gauge Needles with Same Lengths

ObjectivesTo compare vaccine related reactogenicity during primary immunization in healthy infants using 23 vs. 25 gauge needles.MethodsThis randomized controlled trial was conducted in Vaccination Room of the Advanced Pediatrics Center. 155 participants for primary immunization were assigned to two intervention groups (23 vs. 25 gauge). Parent-reported local and systemic reactions were recorded daily for three days after the immunization.ResultsSwelling (24%) and tenderness (21%) were the two most common parent-reported local symptoms followed by restriction of movements (18%) and redness (10%) on day 1. Any local reaction on day 1 was statistically similar in 25 gauge vs. 23 gauge group (RR 0.77; 95% CI: 0.32 to 1.82) (P = 0.54), but fever (day 1) showed higher trend in 23 gauge needle group (RR 2.24; 95% CI: 0.92–5.47) (P = 0.07). Furthermore, on analysis of serially reported local and systemic reactions for 3 consecutive days by generalized estimating equations, odds of redness, swelling, tenderness, restricted movement and fever were statistically similar between two needle groups. On the other hand, median (±SE) crying time (in seconds) was significantly prolonged in the 25 gauge needle (39 ± 2) as compared to 23 gauge group (30 ± 1.3) (log rank test, P = 0.001).ConclusionsThe use of same length needles with narrower (25) or wider (23) gauge did not show significant differences in local reactogenicity during primary immunization. Fever, however, was reduced marginally in 25 gauge group whereas crying duration was significantly shorter with 23 gauge needle. Finally, larger studies are needed to further evaluate objectively the outcome of reactogenicity.

Comparative analysis of virulence determinants, antibiotic susceptibility patterns and serogrouping of atypical enteropathogenic Escherichia coli versus typical enteropathogenic E. coli in India.

The epidemiology of enteropathogenic Escherichia coli (EPEC) and the significance of isolation of atypical EPEC (aEPEC) in childhood diarrhoea have not been well studied in an Indian context. A comparative study was undertaken to investigate virulence determinants, antibiotic susceptibility patterns and serogrouping of typical EPEC (tEPEC) versus aEPEC causing diarrhoea in children. A total of 400 prospective and 500 retrospective E. coli isolates were included. PCR was performed for eae, bfpA, efa, nleB, nleE, cdt, ehxA and paa genes. The Clinical and Laboratory Standards Institutes disc diffusion test was used to determine the antimicrobial susceptibility. Phenotypic screening of extended spectrum β-lactamases (ESBLs), AmpC and Klebsiella pneumoniae carbapenemase (KPC) production, and molecular detection of bla(NDM-1), bla(VIM), bla(CTX-M-15), bla(IMP) and bla(KPC) were performed. aEPEC (57.6 %) were more common as compared with tEPEC (42.3 %). The occurrence of virulence genes was observed to be three times higher in aEPEC as compared with tEPEC, efa1 (14.7 % of aEPEC, 4 % of tEPEC) being the most common. Most of the isolates did not belong to the classical EPEC O-serogroups. The highest resistance was observed against amoxicillin (93.22 %) followed by quinolones (83 %), cephalosporins (37.28 %), cotrimoxazole (35.59 %) and carbapenems (30.5 %). Overall equal numbers of aEPEC (41.17 %) and tEPEC (40 %) were observed to be multidrug-resistant. Fifteen EPEC strains demonstrated presence of ESBLs, five produced AmpC and four each produced metallo-β-lactamases and KPC-type carbapenemases; eight, seven and one isolate(s) each were positive for bla(VIM), bla(CTX-M-15) and bla(NDM-1), respectively. Here, to the best of our knowledge, we report for the first time on carbapenem resistance and the presence of bla(NDM-1) and bla(CTX-M-15) in EPEC isolates from India.

A Community-Based Cluster Randomized Controlled Trial of “Directly Observed Home-Based Daily Iron Therapy” in Lowering Prevalence of Anemia in Rural Women and Adolescent Girls

In a community-based cluster randomized controlled trial, we randomly assigned clusters of anemic women and adolescent girls to either “directly observed home-based daily iron therapy” (DOHBIT; n = 524 in 16 villages) or unsupervised self-treatment at home (n = 535 in 16 villages) for a period of 90 days. Those in the DOHBIT group, when compared with those in the unsupervised self-treatment group, had significantly lower relative risk (RR) of anemia (16.8% vs 35.3%, RR = 0.47 [95% confidence interval (CI) = 0.33-0.65]; P < .0001), higher hemoglobin (Hb) rise of ≥2 g/dL (70.2% vs 42.2%, RR = 1.56 [95% CI = 1.31-1.87]; P <.0001), and nonsignificant trend for lower side effects (3.5% vs 6.7%, RR = 0.49 [95% CI = 0.22-1.08; P < .08) on intention-to-treat analyses. On linear mixed model analysis, the subjects in the intervention group demonstrated higher mean Hb levels (13.01 vs 12.32 g/dL; P < .0001) and higher adherence to iron therapy (93% vs 60%; P < .0001). DOHBIT is effective in lowering the prevalence of anemia in rural women and adolescent girls.
