NsaiD use in Chicken Pox James Harper Chris Phillips Tom Hutchinson
Clinical Scenario-------------------------------- • Paediatric placement week • Nine year old with chicken pox, some infected lesions. • Patient was admitted for intravenous antibiotics. • Paediatric consultant asked me if I would advise giving ibuprofen to a child with chicken pox in the community? Leading Question No?
Why?-------------------------- • There are approximately 700,000 cases of chicken pox a year in England and Wales1 • Over 90% of people in the UK will contract chicken pox before adolescence2 • In children younger than 5 years of age, bacterial skin infection is the most common complication5 • But it is rare: 2.8 per 10004 • Anecdotally Ibuprofen is very commonly used in paediatric patients for fever both as an over the counter and as a prescribed medication. • Ibuprofen is better at bringing down a temperature than paracetamol6
Possible Underlying Mechanism---------------------------------------------- • In vitro studies • Decreases in neutrophil function after exposure to NSAIDs • Specifically aggregation, adherence and degranulation of neutrophils10 • Inhibition of prostaglandin synthesis9 • In vivo • Neutrophils from subjects taking therapeutic doses of ibuprofen, indomethacin, or piroxicam showed profiles of inhibited responses to an infective stimulant8 • Ibuprofen study in rats showed decreased survival from surgical wounds and in a cecal ligation and punction model11 • Suggestion that NSAIDs may play a role, not only in the cause of varicella-associated skin infections, but also in the general worsening of infections.
PICO---------------------------------------------- • Population: • Intervention: • Comparator: • Outcome: • Paediatric Patients with Varicella Zoster • The use of NSAIDs • The use of a placebo/avoidance of NSAIDs • Development of secondary streptococcal skin infections
Search Strategy---------------------------------------------- • PubMed/Cochrane Library • [varicella] AND [ibuprofen OR NSAID] • 140 results of which 14 were relevant and related to skin infections • Removed one in French, one in Spanish, one in Portuguese • 2 BMJ letters • 3 duplicates • 1 retrospective cohort study • 3 case control studies • 1 prospective cohort study • 1 commentary

Dubos F1, Hue V, Grandbastien B, Catteau B, Martinot A. • Multi centre prospective study • 159 children admitted with varicella. 43 of whom developed superadded infections. • NSAIDs were associated with onset of superadded infection (p 0.005)

Durand Let al • International Journal of Clinical Pharmacy • Article summarises that whilst no causal relationship has been definitively demonstrated, an association between NSAID use in varicella and superadded infection, has been found. • Advocates that paracetamol remains the safest antipyretic to use in varicella
The Bottom line---------------------------------------------- • There is evidence of ibuprofen being an independent risk factor for skin infections. • There is evidence of a possible underlying mechanism to support that. • However a persistent high fever after varicella infection may lead to ibuprofen use which itself is probably a sign of incipient soft tissue infection. • Excess fear of ibuprofen can lead to excess use of paracetamol, which in overdose and especially in children can be hepatotoxic7 • Should prescription of NSAIDs be limited in VZV infections?
