A lethal case of generalized tetanus

Tetanus in a vaccinated soil expert - a case report

BACKGROUND

Tetanus is a life-threatening vaccine-preventable disease found more commonly in tropical climates. It accounted for up to 60 deaths annually until the introduction of the tetanus toxoid. It is now rare in Canada by immunization. This study aims to describe a case of tetanus in Saskatchewan with possible occupational exposure.

CASE REPORT

We describe the case of a vaccinated soil expert with tetanus resulting from skin abrasions. This report highlights the early diagnosis, atypical presentation with possible vaccine attenuation and management approach, including acute care, intensive care unit referral, surgical management and physical rehabilitation. We also describe the public health management provided in this case. Despite the severity, the patient returned to his previous home environment with minimal motor sequelae.

CONCLUSION

Occupational exposure to tetanus is an important risk, even in regions where the disease is rare. Prevention through vaccination is a key public health intervention that must be encouraged to avoid health complications that are often fatal.

Generalized tetanus in a landscaper without obvious wounds

Tetanus is rare and potentially fatal infection in the US. Its incidence has declined dramatically over the years in developed countries due to robust immunization programs. We describe a case of generalized tetanus in a 66-year-old inadequately vaccinated landscaper who presented with classical symptoms but did not have any open wounds leading to delay in initial diagnosis but was successfully managed once the diagnosis was established.

A systematic review of tetanus in individuals with previous tetanus toxoid immunization

Objectives

To assess the characteristics of tetanus in previously immunized individuals.

Methods

A systematic literature search was undertaken using Ovid MEDLINE(R) and EMBASE databases for articles published between 1946 and September 3, 2013. The search strategy was developed using MESH terms for "tetanus", "immunization" and "vaccination". Inclusion criteria were articles in English or French that described at least one case of tetanus, immunization history and/or the results of anti-tetanus antibodies. Articles were reviewed for relevant references.

Results

51 unique articles published from1946-2013 were included in the review. The articles described 359 cases of clinical tetanus in individuals with prior receipt of one or more doses of tetanus toxoid vaccine and/or levels of tetanus antibody titres generally considered protective. Of the 210 cases that reported patient status at discharge, 180 (85.7%) survived with only three cases reporting residual deficits.

Conclusion

Tetanus spores are ubiquitous and this report clearly documents that tetanus cases can occur in individuals previously immunized with tetanus toxoid vaccine. Clinicians should not rule out tetanus when clinical symptoms suggest it, regardless of the vaccination history. When treated, the prognosis for tetanus is good. Further research is needed to assess the incidence of tetanus in partially- and fully-immunized populations and determine whether this is due to waning immunity of vaccine failure.

Tetanus is still a deadly disease: a report of six tetanus cases and reminder of our knowledge

We analysed the data in the medical records of six patients admitted for tetanus in the intensive care unit (ICU) of the anaesthesia department in the Medical Faculty of Ataturk University from 1 January 2010 to 31 December 2012. All patients received the generalized form of treatment for tetanus in the ICU. The average age of the patients was 65.33 ± 13.45 years. Treatment modalities were administered to the patients in accordance with the literature. Four patients died despite all therapeutic interventions and two patients were discharged uneventfully. All those who died had chronic disease and infected wounds on their head, but only one patient had an infected wound on his leg. The surviving patients had no chronic illnesses but did have injuries on their legs. The presence of chronic disease increases tetanus-related mortality. More information about the disease must be made available in order to make it preventable with regular vaccinations.
