Episodic Viral Wheeze and Multiple Trigger Wheeze in preschool children: A useful distinction for clinicians?

Classification and pharmacological treatment of preschool wheezing: changes since 2008

“…First, the distinction between EVW and MTW does not take severity or frequency of episodes into account. In clinical practice, however, these play a major role in deciding which affected children are prescribed daily controller therapy, although the evidence that any controller therapy affects the frequency or severity of wheeze with viral colds in preschool children is scant [5]. Second, it has been argued that the distinction between EVW and MTW is more a marker of disease severity than of different clinical phenotypes [14].…”

Assessment of Controversial Pediatric Asthma Management Options Using GRADE

“…32 The distinction between episodic viral and multiple trigger wheeze does not take severity and frequency of episodes into account, although this is the main driver for starting maintenance therapy. 33 Finally, it has been shown that 90% of wheezing episodes in preschool children are associated with viral infection. 34 According to the working group, this invalidates the concept of viral versus multiple trigger wheeze to an important extent, and it was felt that making the difference on clinical grounds is probably not feasible.…”

“…Det synes å vaere enighet om at den viktigste enkeltfaktoren som indikerer at barn med luftveisobstruksjon har astma, er påvis-ning av allergisk sensibilisering, målt ved hudprikktest eller blodprøver (3,6,7). Sensibilisering indikerer at barnet er atopisk, og det er dermed mer sannsynlig at aktuelle symptomer er debut av tidlig astma (6).…”
