Constrictive bronchiolitis is relatively unresponsive to corticosteroids and is frequently progressive. Corticosteroids are effective in two-thirds of patients with proliferative bronchiolitis, and improvement can be prompt. Therapy is initiated with prednisone at 1 mg/kg/day orally for 1-3 months. The dose is then tapered slowly to 20-40 Bronchiolitis is a generic term applied to varied inflammatory processes that affect the bronchioles, which are small conducting airways less than 2 mm in diameter. In infants and children, bronchiolitis is common and usually caused by viruses (most commonly respiratory syncytial virus, but other viruses include rhinovirus, parainfluenza Bronchiolitis obliterans (BO), also known as obliterative bronchiolitis, constrictive bronchiolitis and popcorn lung, is a disease that results in obstruction of the smallest airways of the lungs (bronchioles) due to inflammation. Symptoms include a dry cough, shortness of breath, wheezing and feeling tired. These symptoms generally get worse over weeks to months. Background: Post-infectious bronchiolitis obliterans (PIBO) is a rare, severe chronic lung disease without optimal treatment. Currently, treatment in children mainly relies on systemic corticosteroids, but long-term use of these drugs may lead to adverse reactions. This study aimed to evaluate the short-term efficacy of the Chronic graft-versus-host disease (cGVHD) of the lung, or bronchiolitis obliterans syndrome (BOS), is a high-risk disease manifestation associated with poor outcomes. Currently available treatments have demonstrated limited clinical efficacy in this setting. Lung transplantation is an important treatment option for patients with advanced lung disease. Survival rates for lung transplant recipients have improved; however, the major obstacle limiting better survival is bronchiolitis obliterans syndrome (BOS). In the last decade, survival after lung retransplantation has improved for transplant recipients with BOS. This manuscript reviews BOS along BOOPthan bronchiolitis obliterans.

InEpler's original series50of57 cases(88%) Bronchiolitis obliterans syndrome (BOS) is a progressive, insidious lung disease affecting allogeneic hematopoietic stem cell transplantation recipients. Unfortunately, there is no standardized approach for treatment of BOS in post-hematopoietic stem cell transplantation patients. Pulmonary rehabilitation is a standard treatment in emphysema, an irreversible obstructive lung disease bronchiolitis Last edited 08/2021 and last reviewed 08/2021 Bronchiolitis is an inflammation of the bronchioles. Epidemics occur in winter, when bronchiolitis may account for half of paediatric hospital admissions (1). It is rarer in the tropics. Bronchiolitis is the most common disease of the lower respiratory tract during the first year of
