Acute epiglottitis in the adult caused by Neisseria meningitidis

Meningococcal serogroup W135 epiglottitis in an adolescent patient

Acute epiglottitis is a severe and potentially life-threatening condition. Since the implementation of Haemophilus influenzae vaccination, the number of cases of epiglottitis has decreased and the proportion of other infectious causes has increased. We report a case of acute epiglottitis in a teenager caused by Neisseria meningitidis, an unusual pathogen.

Case and Literature Review: Adult Acute Epiglottitis – Rising Incidence or Increasing Awareness?

Objective

The prevalence of adult acute epiglottitis is probably more common than is generally appreciated. A retrospective case review in a district hospital and a medical literature search may provide baseline information to guide future strategies.

Methods

Cases of acute epiglottitis in a period of 3 years and 4 months were traced from the hospital computer systems. Medical records were reviewed. Medical literature on “adult acute epiglottitis” was searched through Medline and EMBASE. Relevant full text articles were retrieved through hospital library network.

Results

From February 1998 to June 2001, 11 cases of acute epiglottitis were identified. The age range was 34–78 (mean 47.5, median 41). There was no paediatric case. The male to female ratio was 9:2. Eight presented with fever, sore throat and dysphagia, one presented with dyspnoea and two presented as foreign body in throat. Nine were treated successfully conservatively. Two were intubated prophylactically. There was no case fatality.

Conclusion

Adult acute epiglottitis has become much commoner than its paediatric counterpart. Acute epiglottitis should be suspected in all patients with a sore throat and dysphagia, especially if symptoms are out of proportion to the pharyngeal inflammation.

A new era in supraglottitis? An isolated UK case of supraglottitis secondary toNeisseria meningitidis

Objective:

We report the first UK case of supraglottitis secondary toNeisseria meningitidis.

Method:

Case report with review of the current literature on supraglottitis and its aetiology.

Results:

An 89-year-old woman was referred with worsening symptoms of dysphagia, hoarseness and neck discomfort. After nasopharyngoscopy and neck X-ray, supraglottitis was diagnosed. Prompt treatment comprised nebulised adrenaline, oxygen therapy and intravenous antibiotics. Microbiology samples grewN meningitidis, a notifiable disease in the UK. Public health officials were informed, and full precautions and prophylactic treatment initiated for those at risk. The patient made excellent progress and was discharged several days later.

Discussion and conclusion:

Supraglottitis occurs in <4 per 100 000 population. Following a successful UK childhood immunisation programme, most cases occur in adults. Supraglottitis secondary toN meningitidisis exceptionally rare, with only seven other reported cases worldwide. Morbidity is exceptionally high; over 60 per cent of patients require airway intervention. To our knowledge, this is the first reported UK case of supraglottitis secondary toN meningitidis. This case highlights the important clinical, diagnostic and therapeutic interventions required to prevent complications associated with this potentially fatal condition.

Viral supraglottitis in an adult: a case presentation and literature update

Viral epiglottitis (supraglottitis) is a rare entity but its presentation can mimic that of bacterial epiglottis. Regardless of the causative agent, supraglottitis is a serious disease mostly affecting children and rarely seen in adults. Early suspicion and proper evaluation are mandatory to prevent a life-threatening crisis. In both children and adults the infectious aetiology in supraglottitis is predominantly bacterial while viruses are rare, especially in adults. We describe a case of supraglottitis in an adult in which the symptoms were insidious and blood indices suggested a bacterial aetiology. However, laryngoscopic examination revealed an ulcer over the left aryepiglottic fold and serology was positive for Herpes simplex virus (HSV) IgM. Because supraglottitis due to HSV is a rare entity with few reported cases in the literature, this case is presented to highlight the viral involvement in this disease and its management.

Fulminant meningococcal supraglottitis: An emerging infectious syndrome?

We report a case of fulminant supraglottitis with dramatic external cervical swelling due to associated cellulitis. Blood cultures were positive for Neisseria meningitidis. The patient recovered completely after emergency fiberoptic intubation and appropriate antibiotic therapy. We summarize five other cases of meningococcal supraglottitis, all reported since 1995, and discuss possible pathophysiologic mechanisms.
