Effect of Tetanus Toxoid Vaccine on Neonatal Tetanus

Effect of Tetanus toxoid Vaccine on neonatal TetanusEvaluation of the magnetic core of Tetanus toxoid vaccinum on neonatal lockjawClinical scenarioTetanus is a vaccinum preventable disease caused by a ubiquitous spore-forming bacteria called Clostridium tetani (reference need). Due to its ubiquity, the disease cannot be eradicated (Roper et al. 2007). Tetanus that occurs in neonates between 3-28 days of life is termed neonatal tetanus (CDC, 1997) and the most common focal point of infection in neonates is through the freshly cut umbilical cord (Bennett et al. 1996 Roper et al. 2007). Substantial relegate has been made towards the excreting of maternal and neonatal tetanus (MNT) by the WHO initiative, although it still remains a major(ip) problem in more than 30 developing countries (figure 1) (WHO, 2015).Figure 1. The global map sowing the advancement towards the elimination of maternal and neonatal tetanus.Source WHO. (2015). Online.http//www.who.int/immunization/diseases/MNT E_initiative/en/index4.htmlDeveloped countries such as the United States of America, England and Denmark, incur long ago eliminated tetanus linked neonatal deaths compared to developing countries (Pascual et al. 2003 Simonsen et al. 1987 Rushdy et al. 2003). Haws et al. (2007) mentivirtuosod that in areas where the prevalence of neonatal tetanus is common, vaccinating women against tetanus during pregnancy is likely to prevent the disease. Neonatal tetanus still remains one of the leading causes of infant mortality in many developing countries despite the fact that tetanus vaccine has been available for years (Stanfield et al. 1984). Hence, the aim of this critical judgement is to evaluate the effect of tetanus toxoid vaccine take a leakn to pregnant women to provide effective protection and reduce deaths from neonatal tetanus in analogy to no vaccine.Focused Clinical QuestionTable 1 Search StrategyInclusion and forcing out CriteriaTable 2 search and book binding resultsTotal number of studies = 3 (Blencowe et al., 2010 Maral et al., 2001 and Demicheli et al., 2013). Table 3 CASP screening tool for the appraisal of two Systematic Reviews and one Cross-sectional think over*A cross-sectional appraisal tool does not exist, therefore Maral et al., 2001 was appraised using the systematic review appraisal tool.ExclusionsSummary of best depict Blencowe et al., 2010 Systematic reviewAim/Objective of the Systematic reviewTo evaluate the effect of Tetanus Toxoid vaccination of pregnant women or women of child bearing age on neonatal tetanus mortality.Study DesignSearch StrategyA range of appropriate databases were used such as PubMed, EMASE, Cochrane Libraries and knowledge domain Health Organisation Regional Databases. Suitable search terms were used such as Neonatal Tetanus, Tetanus Toxoid, Neonatal Mortality and Women. Publications in any language were also included.Selection Criteria for comprehension of studiesThe PICO fix up (Patient, hindrance, Compa rison and Outcome) was used in this review to identify the studies to be included as followsPopulation NeonatesIntervention At least two Tetanus Toxoid vaccine dosesComparison Neonates born without Tetanus Toxoid vaccinationOutcome Mortality from Neonatal TetanusRandomised trails and observational studies brush the above criterias were considered in this review.MethodsA systematic review of various databases was carried out to identify suitable studies meeting inclusion criteriaStandardised abstraction forms were used for each outcome of interest for studies meeting the inclusion criteriaStudies not meeting the inclusion criteria, studies which only reported serological outcomes and duplicate reports of studies or trails were all excludedQuality of individual studies and leaven were evaluated according to the CHERG version of the GRADE method to generate an approximate calculation of the effects in cut neonatal mortalityA meta-analysis was carried out using STATA version 10.0 statistic software and stated the mantel-haenszel pooled relative take chances and corresponding 95% assurance intervals (CI)FindingsTwo studies which had no heterogeneity between them (p=0.16) i.e. a high-quality randomised controlled outpouring and a well-designed cohort study with adjustment for publication bias in its analysis, were joined into one meta-analysis to give an estimate of relative risk (RR)= 0.06 (95% CI 0.02-0.2) (Fig. 1). While, three case-control studies each with adjustment for publication bias showed a protective effect of two tetanus toxoid injections during pregnancy (odd ratio (OR) = 0.05 (0.005-0.4) OR=0.1 (0.03_0.4) OR=0.2 (0.03-0.7). overall resultA 94% reduction in neonatal tetanus mortality (95% CI 80-98%). The confidence interval of 95% for these results appear to be accurate.
