Lupus pneumonitis as the initial presentation of systemic lupus erythematosus: case series from a single institution

Abstract

Objective

The aim of this study was to examine the clinical features, treatment and outcome of systemic lupus erythematosus (SLE) patients in our centre who presented with lupus pneumonitis as the initial manifestation.

Methods

We performed a retrospective review of all patients who presented with lupus pneumonitis during the initial SLE manifestation from March 2006 to March 2015.

Results

There were a total of five patients in our study who presented with fever and cough as the main clinical features. All patients had pulmonary infiltrates on chest radiographs. High-resolution computed tomography, which was performed in two patients, showed ground glass opacities with patchy consolidations bilaterally. All patients received high-dose steroids, 80% received intravenous cyclophosphamide and 60% received intravenous immunoglobulin. Two patients died from severe lupus pneumonitis within 2 weeks of admission despite treatment with ventilation, steroids, cyclophosphamide and intravenous immunoglobulin.

Conclusions

Acute lupus pneumonitis is an uncommon presentation of SLE. Mortality in this case series is 40%.
