The long term survival of human lung allograft is hampered by the occurrence of chronic rejection, Bronchiolitis Obliterans Syndrome (BOS). This end-stage disease is normally diagnosed clinically by using the pulmonary function tests. This results in delay of BOS diagnosis and consequently prevents early intervention. It is generally accepted that alloimmunity plays an important role in chronic rejection of the allograft. In this study we analyzed serial serum samples from BOS+ and BOS- patients for sCD30 levels to determine the role of sCD30 to predict the onset of BOS. In contrast to BOS negative patients and normal subjects, 6 out of 9 BOS+ patients (p<0.05) studied had an increase in the sCD30 levels. Significantly, the rise was noted 7.57+/-2.63 months before the clinical diagnosis was evident. Therefore, we propose that the rise in serum sCD30 levels can be used as a marker for the detection of patients who are at risk of development of BOS.

Bronchiolitis obliterans (BO) is a disease characterized by airway obstruction and fibrosis that can occur in all age groups. Bronchiolitis obliterans syndrome (BOS) is a clinical manifestation of BO in patients who have undergone lung transplantation or hematopoietic stem cell transplantation. Persistent inflammation and fibrosis of small airways make the disease irreversible, eventually leading to lung failure.

Objective: Bronchoscopy plays a critical role in the diagnosis and management of lung transplant recipients. We retrospectively evaluated the safety, complications, and efficacy of transbronchial biopsy (TBB) in detecting and grading early rejection.
Materials And Methods: We retrospectively assessed the complications associated with TBB and the adequacy of pathological diagnoses in patients who underwent lung transplantation at Koşuyolu Yüksek İhtisas Training and Research Hospital from December 1, 2016, to April 30, 2023.

Background: Bronchiolitis obliterans syndrome (BOS) is one of the most devastating outcomes of chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This remains an area of unmet clinical need for optimal therapy for BOS patients partly due to the limited understanding of pathogenic mechanisms.
Methods: We collected blood samples from 22 patients with cGVHD and 11 patients without cGVHD following allo-HSCT.

Currently, the barrier to successful lung transplantation is ischemia and reperfusion injury, which can lead to the development of bronchiolitis obliterans. Paclitaxel and methotrexate are drugs known to inhibit cell proliferation and have anti-inflammatory effects, and the association of these drugs with cholesterol-rich nanoparticles has been shown to be beneficial in the treatment of other transplanted organs. Thirty-three male Sprague Dawley rats were divided into 3 groups: Basal group, no intervention; Control group, received only nanoparticles; Drug group, paclitaxel and methotrexate treatment.

After the cancellation of COVID-19 epidemic control measures in 2023, cases of pediatric bronchiolitis caused by Mycoplasma pneumoniae (MP) have been reported successively, with some children experiencing residual bronchiolitis obliterans (BO). Currently, the diagnosis of bronchiolitis Mycoplasma pneumoniae pneumonia (MPP) primarily relies on high-resolution computed tomography (HRCT). To establish a predictive model for bronchiolitis MPP, a retrospective analysis was conducted.
