RESULTS: Among forty-one patients who received lung transplant, 3 children patients and 2 patients with concurrent liver transplant were excluded. Among 36 patients, 24 (67%) were steroid group and remaining 12 (33%) were non-steroid group. Male-to-female ratio was 1.43 and median age was 44.5 years old (range: 18-62). Bilateral lung transplantation was performed in 14 cases. Most common cause for Lung transplantation was ILD (41%), followed by ARDS due to toxic material (humidifier cleaning solution), pneumonia, and near-drowning. Rare causes were BO after HSCT and pulmonary hypertension. Median APACHE II score at ICU admission was 17.5 (median 10-41). During median follow-up of 32 months, there were 7 mortalities. There were no differences in sex, age, type of transplant, and cause of transplant between steroid group and non-steroid group, while there were tendency of increased APACHE II score in steroid group compared to non-steroid group (15.0 vs 5.5, p=0.054). Post-transplant ICU stay and postoperative hospital stay were longer in steroid group compared to non-steroid group (18.5 vs 10.0 p=0.026, 83.0 vs 46.8 p=0.009, respectively). While infection-related mortality was higher in steroid group (7 vs 0%, p=0.041), there was no difference in overall mortality (p=0.104).
