Albuterol Use in Children Hospitalized with Human Metapneumovirus Respiratory Infection

الملخص EN

Introduction.

Human metapneumovirus (HMPV) is a paramyxovirus from the same subfamily as respiratory syncytial virus (RSV) and causes similar acute lower respiratory tract infection.

Albuterol in the setting of acute RSV infection is controversial and has not yet been studied in HMPV.

We sought to determine the frequency of albuterol use in HMPV infection and the association between albuterol administration and patient outcomes.

Methods.

We conducted a retrospective cohort study identifying all patients hospitalized in a tertiary care children’s hospital with laboratory-confirmed HMPV infection between January 2010 and December 2010.

Results.

There were 207 patients included in the study; 57% had a chronic medical condition.

The median hospital length of stay was 3 days.

Only 31% of patients in the study had a documented wheezing history, while 69% of patients received at least one albuterol treatment.

There was no difference in length of stay between patients who received albuterol and those who did not.

Conclusion.

There is a high frequency of albuterol use in children hospitalized with HMPV infection.

As with RSV, evidence may not support routine use of bronchodilators in patients with acute HMPV respiratory infection.

Research involving additional patient outcomes and illness severity indicators would be useful in future studies.
