Background: Bronchiolitis obliterans syndrome (BOS) is a rare, progressive and irreversible airway disease associated with significant mortality after allogeneic hematopoietic stem-cell transplantation (HSCT). In this study, we investigated the therapeutic effect of high-dose budesonide/formoterol (320/9 µg bid) in patients with BOS after HSCT already using low-dose budesonide/formoterol (160/4.5 µg bid). Methods: After a retrospective chart review, patients who were initially treated with budesonide/formoterol 160/4...

OBJECTIVE: To study the value of anti-neutrophil cytoplasmic antibody (ANCA) in assessing the severity of bronchiolitis obliterans (BO) in children. METHODS: A prospective analysis was performed on 59 children who were diagnosed with BO from June 2009 to October 2014. ELISA was used to measure the concentrations of myeloperoxidase (MPO)-ANCA and proteinase 3 (PR3)-ANCA in serum. According to the results of ELISA, the children were divided into three groups: double-negative ANCA (n=22), single-positive ANCA (n=17), and double-positive ANCA (n=20)...

Left-unilateral single-lobe lung transplantation from a living donor was performed in a 4-year-old boy who suffered from severe respiratory failure caused by bronchiolitis obliterans (BO) as a result of graft versus host disease (GVHD) after peripheral blood stem cell transplantation (PBSCT). The patient grew well during his early childhood years, with an excellent lung allograft function. However, severe thoracic scoliosis occurred 7 years after lung transplantation, which ultimately resulted in compression of the lung allograft followed by severe respiratory dysfunction, and the patient became dependent on mechanical ventilation support...

Serum creatinine (SCr) and estimated glomerular filtration rate (eGFR) are standard biomarkers of contrast-induced nephropathy (CIN). However, recent studies suggest that serum neutrophil gelatinase-associated lipocalin (sNGAL) and urine neutrophil gelatinase-associated lipocalin (uNGAL) may be better predictors, particularly within 24 hours of contrast medium exposure.We conducted a prospective, observational cohort study of 107 consecutive patients diagnosed with arteriosclerosis obliterans between February 2016 and October 2018...

Arterial occlusive disease of the limb is very rare in children. Buerger's disease (BD) is a nonatherosclerotic, segmental inflammatory arteritis affecting the small and medium-sized vessels of the extremities. We report BD in a 16-year-old male presenting with arterial insufficiency of left foot and history of smoking cigarettes and cannabis for 2 years. BD was diagnosed based on history of smoking in combination with clinical, laboratory, and radiologic findings. Pediatric hemato-oncologists should consider BD in the differential diagnosis in adolescents who smoke cigarettes and/or cannabis and present with vascular insufficiency of the hands and/or feet...

BACKGROUND: Phenotyping chronic lung allograft dysfunction (CLAD) in single lung transplant (SLTX) recipients is challenging. The aim of this study was to assess the diagnostic and prognostic value of longitudinal lung function tests in SLTX recipients with CLAD. METHODS: A total of 295 SLTX recipients were analyzed and stratified according to native lung physiology. In addition to spirometry, measurements of static lung volumes and lung capacities were used to phenotype patients and to assess their prognostic value...

Bronchiolitis obliterans syndrome (BOS) after allogeneic hematopoietic cell transplantation (allo-HCT) usually confers poor prognosis and high mortality. Currently, therapeutic options are limited. Here we report an 18-year-old man with acute myeloid leukemia developed BOS after allo-HCT and responded poorly to inhaled corticosteroids and short-acting β-agonist, azithromycin, montelukast, and immunosuppressants. Then he started nintedanib treatment, and the symptoms of nonproductive cough and dyspnea were alleviated gradually...

BACKGROUND: Chronic lung allograft dysfunction (CLAD), is a major hurdle for long-term lung allograft survival after lung transplant and roughly 50% of lung transplant recipients (LTxRs) develop CLAD within 5 years. The mechanisms of CLAD development remain unknown. Donor-specific immune responses to human leukocyte antigen (HLA) and lung self-antigens (SAgs) are vital to the pathogenesis of CLAD. Reduction in Club cell secretory protein (CCSP) has been reported in bronchoalveolar lavage (BAL) fluid samples from LTxRs with bronchiolitis obliterans syndrome (BOS)...

Organizing pneumonia (OP), previously known as bronchiolitis obliterans OP, is a diffuse parenchymal lung disease affecting the distal bronchioles, alveolar ducts, and alveolar walls. Pulmonary infections, especially bacterial and viral diseases, are known to be associated with the secondary form of OP. OP secondary to fungal infections is less common. Here, we report a case of OP associated with pneumocystis pneumonia (PCP) in a kidney transplant recipient on tacrolimus-based triple immunosuppression. The index case had developed new lung consolidation toward the end of trimethoprim-sulfamethoxazole therapy for PCP...

REVIEW
Nobuyuki Yoshiyasu, Masaaki Sato
Chronic lung allograft dysfunction (CLAD) following lung transplantation limits long-term survival considerably. The main reason for this is a lack of knowledge regarding the pathological condition and the establishment of treatment. The consensus statement from the International Society for Heart and Lung Transplantation on CLAD in 2019 classified CLAD into two main phenotypes: Bronchiolitis obliterans syndrome and restrictive allograft syndrome. Along with this clear classification, further exploration of the mechanisms and the development of appropriate prevention and treatment strategies for each phenotype are desired...

PURPOSE: Survivors of allogeneic hematopoietic stem cell transplantation (allo-HSCT) are at risk for cardiopulmonary adverse events. Data on long-term effects on cardiorespiratory fitness are limited. To address the gap in knowledge, we aimed to determine peak oxygen uptake (V̇O2 peak) and identify associations between cardiorespiratory fitness and clinical characteristics, self-reported physical activity, cardiac, and pulmonary function. METHODS: In a nationwide, single-center cross-sectional study, 90 survivors [aged median (range) 35 (17-54) years, 56% females] were examined, 17 (6-26) years after allo-HSCT...

Bronchiolitis obliterans is a clinical entity which results from a variety of etiologies and has a detrimental impact on patients' quality of life when it remains undiagnosed and untreated. Due to its non-pathognomic clinical symptoms and signs, physicians often proceed to radiological examination, especially with high resolution chest tomography. Histological examination reveals constrictive bronchiolitis, the pathological definition of bronchiolitis obliterans. Due to an almost normal aspect of the lung parenchyma this condition can be missed...
