Abstract

Background. The standard treatment of acute cellular rejection after lung transplantation (LTx) is a high-dose steroid pulse therapy. In our center, this therapy is also the standard of care for LTx recipients with acute loss of forced expiratory volume in 1 second (FEV1), after excluding specific causes such as acute rejection on biopsy. The aim of this retrospective study was to evaluate the safety and efficacy of steroid pulse therapy. Methods. From 2015 to 2018, 33 consecutive patients (17 male patients, mean age +/- SD, 50.5 +/- 12.5 years) were included. All patients underwent routine examinations to exclude acute cellular rejection and other specific causes. FEV1 was routinely measured after 5 days, and 1, 3, and 6 months. Positive response to steroid pulse therapy was defined by increase of FEV1 > 10%. Results. The mean decrease +/- SD from baseline in FEV1 at the start of steroid pulse therapy was 380 +/- 630 mL (P = .02). FEV1 changed after 5 days by 170 +/- 180 mL (P = .0007), and after 1 month by 140 +/- 230 mL (P = .70), 3 months by -60 +/- 240 mL (P = .15), and 6 months by -80 +/- 290 mL (P = .73). A positive response was observed in 21% of patients after 3 months and 12% after 6 months. High bronchoalveolar lavage (BAL) eosinophil count correlated with a higher FEV1 after steroid pulse therapy. Serious complications were observed in 4 out of 33 patients (12%) with 1 fatal event (pneumonia). Conclusions. Only a minority of patients after LTx with loss of FEV1 after exclusion of acute cellular rejection benefit from steroid pulse therapy. Patients with BAL eosinophilia are more likely to respond. However, severe complications were observed.
