Bronchiolitis Obliterans Syndrome: Understanding

Bronchiolitis Obliterans Syndrome: Overview

Bronchiolitis obliterans is also known as obliterative bronchiolitis or constrictive bronchiolitis. When it occurs after lung transplantation or hematopoietic stem cell transplantation (HSCT), it is called bronchiolitis obliterans syndrome. Bronchiolitis obliterans is a type of obstructive lung disease of the small airways. It is a rare disease with characteristic features of fibrosis of terminal and distal bronchioles and spirometry showing airflow obstruction. It usually leads to a progressive decline in lung function and has variable outcomes.

Bronchiolitis obliterans can develop due to a variety of risk factors. It is one of the most common noninfectious complications after lung transplant and hematopoietic stem cell transplantation. Other etiologies include exposure to inhaled toxins and gases, such as sulfur mustard gas, nitrogen oxides, diacetyl (used as popcorn flavoring), fly ash, and fiberglass. Bronchiolitis obliterans is also associated with autoimmune disorders, especially rheumatoid arthritis, systemic lupus erythematosus (SLE), and less commonly with inflammatory bowel disease. It is known to occur after a respiratory viral infection, particularly adenovirus and respiratory syncytial virus, especially in children. Other infections associated with bronchiolitis obliterans are HIV, mycoplasma, bacteria, fungi, and Human Herpes Virus (HHV) 8. Rare conditions like Castleman disease and paraneoplastic pemphigus have also been linked to bronchiolitis obliterans. Other associations include microcarcinoid tumorlets and cryptogenic constrictive bronchiolitis.

The most common symptoms of bronchiolitis obliterans include a dry cough, shortness of breath, wheezing, and feeling tired. These symptoms generally start gradually and worsen over weeks to months. Patients often experience exercise intolerance and may feel extremely short of breath and exhausted after moderate physical exertion. The symptoms are usually persistent and unrelated to factors such as weather, unlike asthma. In some cases, symptoms can occur suddenly. Bronchiolitis obliterans can also cause other associated symptoms depending on the underlying cause, such as a skin rash due to toxin exposure or complications from chemotherapy following a lung or bone marrow transplant.

The treatment of bronchiolitis obliterans syndrome (BOS) after lung transplantation involves a combination of therapies. First-line treatment includes systemic corticosteroids, calcineurin inhibitors (cyclosporine or tacrolimus), and azithromycin. Other therapies that may be used include extracorporeal photopheresis, montelukast, and re-transplantation in selected cases. Prompt treatment of complications, such as infections, is also important in managing patients with BOS.

Bronchiolitis Obliterans Syndrome Emerging Drugs Chapters

This segment of the Bronchiolitis Obliterans Syndrome report encloses its detailed analysis of various drugs in different stages of clinical development, including phase III, II/III, II, I, preclinical and discovery. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Bronchiolitis Obliterans Syndrome Emerging Drugs

• Liposomal Cyclosporine A: Zambon

Liposomal Cyclosporine A for Inhalation (LCsAi) is a novel liposomal formulation of cyclosporine A developed for inhaled delivery to the lungs. Calcineurin inhibitors (CNIs), like cyclosporine A, are highly potent immunosuppressive drugs and a cornerstone of lung transplant medicine. LCsAi is administered via a drug-specific investigational eFlow technology nebulizer system (PARI Pharma GmbH). The investigational drug-device combination is designed to deliver LCsAi to the site of disease in the lung. LCsAi received orphan drug designation for the treatment of BOS from the US Food and Drug Administration and European Medicines Agency. The drug is currently being evaluated under Phase III clinical trial for the treatment of patients with Bronchiolitis Obliterans Syndrome.
