title: Role of a proprietary propolis-based product on the wait-and-see approach in acute otitis media and in preventing evolution to tracheitis, bronchitis, or rhinosinusitis from nonstreptococcal pharyngitis.
abstract: Antipyretics and/or anti-inflammatory drugs along with a wait-and-see approach are the only treatments recommended in early acute otitis media (AOM) or viral pharyngitis. Propolis has been widely investigated for its antibacterial, antiviral, and anti-inflammatory properties and could perhaps be administered as an add-on therapy during watchful waiting in AOM or for better control of symptoms in nonstreptococcal pharyngitis. However, propolis has well-known problems of poor solubility and low oral bioavailability. We therefore analyzed a proprietary propolis-based product (Propolisina®) developed to overcome these limitations, in a retrospective, open-label, controlled study ofStreptococcus pyogenes-negative children with a diagnosis of AOM or pharyngitis. Our results show that the use of propolis supplement for 72 hours lessens the severity of AOM and viral pharyngitis, reduces the use of antipyretics and anti-inflammatory drugs, and decreases the rate of evolution to tracheitis, bronchitis, and rhinosinusitis. Our study shows that propolis could be used as a safe add-on therapy in case of AOM and/or viral pharyngitis.
