Abstract
Pneumocystis jirovecii pneumonia (PCP) is classified as PCP with human immunodeficiency virus (HIV) and non-HIV PCP, and the two forms differ in progression and prognosis. Although early treatment is necessary, the diagnosis of non-HIV PCP is often difficult because of the underlying diseases. However, the outcome with treatment delay remains unclear because there are no concrete data indicating a worsened clinical situation or increased complications related to delayed therapy initiation. We retrospectively examined patients with non-HIV PCP admitted to Tokyo Women's Medical University Hospital from November 2008 to October 2010. The relationship between intubation with mechanical ventilation (within 1 week after starting treatment) and treatment delay was investigated. Treatment delay was defined as the period, in days, from onset to therapy initiation. In total, 24 confirmed non-HIV PCP cases were included. Median treatment delay was 7 ± 4.83 days (1-20 days). Twelve of 24 cases (50 %) were intubated, and 11 (45.8 %) died of their underlying diseases within 90 days. Treatment delay was more than 7 days in the intubation group, but was within 7 days in 9 of 12 nonintubation cases. The difference in treatment delay was significant (p = 0.0071) between the intubation and nonintubation groups, but there were no significant differences in survival rate at 90 days or other findings. We conclude that starting treatment within 7 days after onset is important because intubation and mechanical ventilation may be avoided in many cases.
