pulmicort and Bronchiolitis-Obliterans

Systemic steroids are the standard treatment for bronchiolitis obliterans syndrome (BOS) after allogeneic hematopoietic stem cell transplantation (HSCT) despite their poor efficacy and disabling side effects.. To evaluate the effectiveness and tolerance of budesonide/formoterol as an alternative treatment for BOS after HSCT.. In this randomized, double-blind, placebo-controlled study, we randomly assigned 32 HSCT recipients with mild/severe BOS to receive budesonide/formoterol or placebo for 6 months. The primary outcome was the change in the FEV1 after 1 month of treatment (M1) compared with the baseline value. Patients were unblinded at M1 if there was no improvement in the FEV1. Those who had initially received placebo were switched to budesonide/formoterol. Intention-to-treat analysis was performed to assess the primary outcome. Additional analyses took scheduled treatment contamination into account.. At M1, the median FEV1 increased by 260 ml in the budesonide/formoterol arm compared with 5 ml in the placebo arm (P = 0.012). The median increases in the FEV1 at M1 relative to the baseline value for the treated and placebo groups were 13 and 0%, respectively (P = 0.019). Twenty-five patients received budesonide/formoterol during the study. The median difference in the FEV1 between the baseline and after 1 month of treatment for these patients was +240 ml (P = 0.0001). The effect of budesonide/formoterol on the FEV1 was maintained in the 13 patients who completed 6 months of treatment.. Budesonide/formoterol administration led to a significant improvement in the FEV1 in patients with mild/severe BOS after allogeneic HSCT. Clinical trial registered with www.clinicaltrials.gov (NCT00624754).

Bronchiolitis obliterans syndrome (BOS) is the lung manifestation of chronic graft-versus-host disease after hematopoietic stem cell transplantation (HSCT). We assessed whether inhaled tiotropium add-on to the combination regimen including budesonide/formoterol improve pulmonary function and the chronic obstructive pulmonary disease assessment test (CAT) scores in patients with BOS.. Post-HSCT patients diagnosed as BOS in Seoul St. Mary's Hospital were reviewed retrospectively. Patients defined as BOS and treated with budesonide/formoterol/tiotropium combination therapy after budesonide/formoterol therapy from January 2011 to June 2019 were enrolled.. Total of 86 patients were evaluated. After tiotropium add-on, the absolute FEV1 increased significantly from 1.47 ± 0.49 to 1.53 ± 0.57 L (p = 0.023) and the % predicted FEV1 from 45.0 ± 12.8 to 46.8 ± 14.5% (p = 0.031). The % predicted DLCO increased significantly after tiotropium add-on (from 61.6 ± 16.7 to 64.3 ± 16.3%, p = 0.028). Among 56 patients with complete CAT scores, no significant change was present in total CAT scores. In all, 30 of the 72 patients (41.7%) evidenced FEV1 increases > 100 mL, and 20 of 56 patients (35.7%) had CAT score decreases of ≥ 2 points. When the FEV1 and CAT scores were combined, the overall response rate to tiotropium add-on was 56.2% (41/73). The response group evidenced a significantly greater FVC increase, and a significant decrease in the RV/TLC ratio compared to the no-response group.. Inhaled tiotropium add-on to combination budesonide/formoterol significantly improved lung function, but not respiratory symptoms, in patients with post-HSCT BOS.

To evaluate the safety and effectiveness of a novel therapeutic regimen for bronchiolitis obliterans sydrome (BOS) affter hematopoietic stem cell transplantation (HSCT).. Seven patients who had received HSCT and had been diagnosed as BOS were enrolled in this study. They received weekly intravenous injection of umbilical cord-derived mesenchymal stem cells (MSC) at a dose of 1 × 10(6)/kg for 4 weeks. Budesonide was given orally at a daily dose of 0.25 g, and salmeterol was inhaled at a dose of 4.5 µg for 3 times per day. Methylprednisolone was given at a dose of 1 mg/(kg·d) for 2 weeks when respiratory failure occured. The dose of methylprednisolone was tapered to 0.25 mg/(kg·d) after 4 weeks and was adjusted according to the occurrence and severity of chronic graft-versus-host disease (cGVHD).. The therapy was generally safe and no severe acute toxicity was observed. One patient died of heart failure during the treatment, the other 6 patients were alive and the pulmonary function parameters including FEV1, FEV1/FVC, PaO2 and AaDO2 were significantly improved after 6 months as compared with the baseline parameters (P < 0.05).. MSC combined with budesonide, almeterol and azithromycin has been confirmed to be generally safe and can reduce the dose of glucocorticoid in treatment of BOS after HSCT.

Bronchiolitis obliterans (BO) is a potentially life-threatening complication following allogeneic stem cell transplantation (SCT) and usually carries a poor prognosis. Immunosuppressive medications are the main treatment, but are rarely effective, especially when the disease is severe. Thus, both early detection and alternative therapeutic approaches of post SCT BO are needed. We report our experience with Budesonide/Formoterol, an inhaled steroid and long-acting bronchodilatator combination, in a group of patients with mild to moderately severe BO after SCT whose systemic immunosuppressive treatment had not been modified. Thirteen patients were treated. The diagnosis of BO was based on the presence of respiratory symptoms and air-trapping on expiratory lung high-resolution computed tomography in all patients, associated with irreversible airflow obstruction in seven cases. The median follow-up was 12.8 months (range: 5-29 months). All patients improved clinically, and both forced expiratory volume in 1 (FEV(1)) and mean expiratory flow values increased significantly during follow-up (534+/-268 ml in absolute values and 36+/-27% compared to pretreatment values for FEV(1); P<0.02). These encouraging results provide new insights in the therapeutic approach of BO after SCT and require confirmation in a larger group of patients with a longer follow-up.
