The BMI, obstruction, dyspnea, and exercise capacity (BODE) score is used to inform prognostic considerations for lung transplantation for COPD, but it has not been validated in this context. A large proportion of mortality in COPD is attributable to comorbidities that could preclude transplant candidacy. We hypothesized that patients with COPD who are selected as transplant candidates experience better survival than traditional interpretation of BODE scores might indicate. ⋯ Extrapolation of prognosis based on the BODE score overestimates mortality risk in lung transplantation candidates with COPD. This is likely due to a lower prevalence of comorbid conditions attributable to the lung transplantation evaluation screening process.

Obesity is common among individuals with COPD and associated with increased COPD morbidities. However, little is known about the impact of weight reduction on COPD-related outcomes in patients who are obese. ⋯ The risk of an ED visit or hospitalization for AECOPD substantially decreased after bariatric surgery in patients who are obese. This observation suggests the effectiveness of substantial weight reduction on COPD morbidity.

It has been difficult to determine the individual impact of prenatal and postnatal tobacco smoke exposure (TSE) on childhood lung function, as children are often exposed to both. ⋯ Current TSE was not independently associated with airflow obstruction in school-aged children. Prenatal TSE was associated with airflow obstruction in children with asthma. Repeated studies into potential mediators and confounders of this relationship are needed.

Previously, we and other investigators have described reversible loss of lung elastic recoil in patients with acute and persistent, moderate-to-severe, chronic, treated asthma who never smoked, and its adverse effect on maximal expiratory airflow. In four consecutive autopsies, we reported the pathophysiologic mechanism(s) has been unsuspected mild, diffuse, middle and upper lobe centrilobular emphysema. ⋯ As documented now in five cases, unsuspected microscopic mild centrilobular emphysema is the sentinel cause of loss of lung elastic recoil. This contributes significantly to expiratory airflow obstruction in never-smoking patients with asthma, with normal diffusing capacity and near-normal lung CT scan results.

Interstitial lung disease (ILD) is a significant complication of Sjögren syndrome (SS) associated with increased morbidity and mortality. The mainstay of treatment remains corticosteroid administration, with or without additional immunosuppressive therapies. ⋯ Topical tacrolimus has been effective for ocular symptoms in SS, but systemic therapy has not been reported. We describe the first case, to our knowledge, of the successful use of a combination of systemic tacrolimus and abatacept in severe refractory SS and related ILD.
