ABSTRACT
Supraglottitis is a potentially life-threatening condition. It is now uncommon due to the Haemophilus influenzae type B vaccination and is more recently caused by Streptococcus pneumoniae, S. pyogenes, H. influenzae non-type B, H. parainfluenzae, Staphylococcus aureus and Pasteurella multocida Very rarely, it can cause necrotising supraglottitis/epiglottitis, and this has been reported in immunocompromised individuals. We present a unique case of multipathogenic supraglottitis causing laryngeal fibrinoid necrosis in an immunocompetent patient. During his admission, the patient was critically unwell and required surgical intervention and tracheostomy. However, he made a full recovery with no persisting morbidity. We believe that this was owed to the aggressive antimicrobial therapy, timely surgical management of the disease process and the patientâ™s immunocompetency.

Acute supraglottitis is a medical emergency as it can rapidly lead to airway compromise. With routine pediatric immunization for Hemophilus influenzae serotype b, supraglottitis is now more prevalent in adults, with a shift in the causative organisms and a change in the natural history of this disease. Here, we present a case of supraglottitis due to group B streptococcus that occurred in an adult with previously undetected immunoglobulin 4 (IgG4) and complement protein C2 deficiency.

BACKGROUND: In England and Wales, the incidence of invasive meningococcal disease has been declining for more than a decade, but meningococcal group W (MenW) cases have been increasing since 2009. METHODS: Public Health England conducts enhanced national surveillance of invasive meningococcal disease in England and Wales. Detailed clinical information was obtained for all laboratory-confirmed MenW cases diagnosed during 3 epidemiologic years (2010-2011 to 2012-2013), alongside whole-genome sequencing analysis of the clinical isolates. RESULTS: The year-on-year increase in invasive MenW disease across all age groups since 2009-2010 was due to rapid endemic expansion of a single clone belonging to the sequence type 11 complex (cc11). In 2013-2014, MenW was responsible for 15% of all invasive meningococcal disease. All but 1 of the recent MenW:cc11 isolates were very closely related, consistent with recent clonal expansion. Clinical follow-up of all 129 MenW cases diagnosed during 2010-2011 to 2012-2013 revealed that most patients were previously healthy (n = 105 [81%]), had not travelled abroad prior to illness and the majority presented with septicemia (n = 63 [49%]), meningitis (n = 16 [12%]) or both (n = 21 [16%]); however, one-quarter had atypical presentations including pneumonia (n = 15 [12%]), septic arthritis (n = 9 [7%]), and epiglottitis/supraglottitis (n = 5 [4%]). Forty-eight (37%) required intensive care and 15 (12%) died. There was no association between infecting strain, clinical disease, or outcome. CONCLUSIONS: The recent increase in invasive MenW disease in England and Wales is due to rapid endemic expansion of a single clone belonging to cc11 and is associated with severe disease with unusual clinical presentations. This increase will require careful monitoring in the coming years.

OBJECTIVE: We report the first UK case of supraglottitis secondary to Neisseria 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 grew N 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 to N meningitidis is 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 to N meningitidis. This case highlights the important clinical, diagnostic and therapeutic interventions required to prevent complications associated with this potentially fatal condition.
