Effectiveness of pulse methylprednisolone in patients with non-human immunodeficiency virus pneumocystis pneumonia: a multicentre, retrospective registry-based cohort study
Abstract
A recent database study and meta-analysis reported that adjunctive glucocorticoid therapy reduces mortality in patients with non-human immunodeficiency virus-associated (non-HIV) Pneumocystis jirovecii pneumonia (PCP), having hypoxemia. However, the optimal glucocorticoid dose remains unclear. Our study aimed to evaluate the effectiveness of pulse methylprednisolone compared with mild-to-moderate steroid doses in patients with non-HIV PCP. This multicentre retrospective cohort study included adults with non-HIV PCP receiving adjunctive steroids at three Japanese tertiary care hospitals from June 2006 to March 2021. Patients were categorised into pulse methylprednisolone and mild-to-moderate dose groups. Pulse methylprednisolone involved an initial intravenous infusion of 500–1000 mg methylprednisolone daily, while the mild-to-moderate dose was lower. Primary and secondary outcomes were 30-day and 180-day mortality from treatment initiation. Patient characteristics were adjusted using propensity score analysis with overlap weighting. Subgroup analysis focused on patients with respiratory failure. The study included 139 patients with non-HIV PCP: 55 in the pulse methylprednisolone group and 84 in the mild-to-moderate dose group. After adjusting for patient background, 30-day mortality (14.2% vs. 15.5%, P = 0.850) and 180-day mortality (33.5% vs. 27.3%, P = 0.516) did not differ significantly between groups. Subgroup analysis revealed no significant associations among patients…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 139 participants or records.
