OBJECTIVE: Direct hemoperfusion with polymyxin B-immobilized fiber columns (PMX-DHP) has been used for the treatment of septic shock. It was recently suggested that PMX-DHP may also be effective in acute exacerbations of idiopathic pulmonary fibrosis (IPF). However, all previous reports are case series without controls. The aim of the study was to determine the effects of PMX-DHP on the prognosis of the patients with rapidly progressive interstitial lung diseases (ILDs) in a case-control setting. METHODS: We herein retrospectively examined the clinical records of consecutive patients with acute exacerbation of IPF or rapidly progressive ILDs treated in our institute. We excluded those who had been treated with steroid pulse therapy for lung diseases, including those who had been taking more than 15 mg of oral prednisolone daily, or had undergone an operation within one month before the onset of acute respiratory failure. We compared the results of the laboratory tests and survivals between patients treated with and without PMX-DHP. RESULTS: Twenty-six patients were enrolled in the study. Among them, 13 patients were treated with PMX-DHP in addition to immunosuppressive therapy, including steroid pulse therapy. The mean survival time of patients treated with PMX-DHP tended to be longer than patients not treated with PXM-DHP (p=0.067). Six patients who underwent PMX-DHP on the first day of steroid pulse therapy had significantly longer survival times than those who were treated with standard medication alone (p<0.01). CONCLUSION: These results suggest that PMX-DHP performed on the first day of steroid pulse therapy may improve the prognosis of patients with rapidly progressive ILDs.
