Intrathecal vs. intramuscular administration of human antitetanus immunoglobulin or equine tetanus antitoxin in the treatment of tetanus: a meta-analysis.

چکیده
BACKGROUND Mortality caused by tetanus is still a serious health problem in developing countries. Apart from immunization, early treatment with equine antitetanus serum (ATS) or human tetanus immunoglobulin (TIG) is the real treatment that can avoid death. On pathophysiological grounds intrathecal administration would be preferred because of high concentrations of the antiserum in cerebrospinal fluid and thus around the nerve roots. Many studies concluded on its effectiveness whereas others did not find any superiority of this method. However, most of those studies were not random and/or had no sufficient weight. OBJECTIVE To assess the efficacy of intrathecal therapy with ATS in neonates and adults. METHODS Meta-analysis: Clinical trials were identified by searching Medline, the Cochrane library and Current Contents. Published randomized studies in English or French comparing intrathecal therapy and intramuscular therapy (IMS) were analysed with Revman, R, and Stata software. Treatment effects were evaluated by relative risk (RR) between intrathecal vs. intramuscular administration. RESULTS A total of 942 patients were included in 12 trials, 484 in the intrathecal group and 458 in the intramuscular one. The combined RR of mortality for intrathecal vs. IMS was 0.71 (95% CI, 0.62-0.81). The superiority of intrathecal therapy also emerged when the analysis was performed in subcategories of both adults and neonates and for high and low dose of intrathecal serotherapy. Intrathecal administration of ATS or TIG is more beneficial than intramuscular administration in the treatment of tetanus.

In a prospective study, 161 infants with neonatal tetanus were randomised to receive (a) standard treatment, or (b) standard treatment together with intrathecal equine antitetanus serum, or (c) intrathecal antitetanus serum with systemic betamethasone. There was no difference in survival between the three treatment groups in infants with severe tetanus, but in mild tetanus those who received st...

Pharmacological management of tetanus: an evidence-based review
Tetanus is becoming rarer in both industrialized and developing nations due to an effective vaccination program. In 2010, the World Health Organization estimated there was a 93% reduction in newborns dying from tetanus worldwide, compared to the situation in the late 1980s. Due to its rarity, many diagnostic delays occur as physicians may not consider the diagnosis until the manifestations beco...
