Abstract

Background

Pneumocystis jiroveci pneumonia (PJP) is a severe and lethal opportunistic infection in the immunocompromised patients. As the increasing usage of immunosuppressants, the incidence of non-HIV related PJP has increased in recent years. Still, there is little research regarding children with PJP. The aim of this study is to understand PJP more among pediatric population.

Methods

We reviewed the medical records of the patients with PJP in National Taiwan University Hospital from 2014 to 2017. Diagnosis was made if the patient met all of the criteria: presence of relevant pulmonary symptoms and signs, pulmonary infiltrates on images, detection of Pneumocystis jiroveci from respiratory specimens via polymerase chain reaction (PCR), and received antibiotics for PJP.

Results

Twenty children and 132 adults were enrolled in this study. The most common underlying diseases among children included malignancy (40%), post-transplantation (30%), and primary immunodeficiency (20%). The major underlying diseases in adults included malignancy (36%), HIV with acquired immunodeficiency syndrome (AIDS) (31%), and autoimmune diseases (24%). There is no significant difference in the clinical manifestations, mortality, and complication between children and adults, but children tended to have less chance of using alternative antibiotics, methylprednisolone and inhaled nitric oxide (NO). The chance of concomitant cytomegalovirus disease was also significantly lower in pediatric patients.

Conclusion

No significant difference was found in the clinical manifestations, mortality, and complication between children and adults, but children tended to have lesser chance of using alternative antibiotics, methylprednisolone and inhaled NO. The chance of associated cytomegalovirus (CMV) disease was also significantly lower in children.
