September’s Current Opinion in Pulmonary Medicine has 4-5 review articles each on sarcoidosis (how to handle calcium problems; cardiac sarcoid); interstitial lung disease (biologics for connective-tissue disease related ILD; LAM therapies; stem cell therapy for pulmonary fibrosis), and pulmonary vascular disease. Curr Opin Pulm Med 2011;17.
Unimpressed by the unimpressive results of the CAPACITY trials testing pirfenidone for idiopathic pulmonary fibrosis, the FDA bucked its advisory panel (which had recommended approval) and insisted on another randomized trial in order to reconsider the drug. In July 2011 InterMune started enrollment for ASCEND, which plans to provide results on pirfenidone vs. placebo in [... read more]
King et al report a series of 80 otherwise healthy young vets who failed a 2-mile run fitness test due to dyspnea at Fort Campbell, KY. Many had been exposed to sulfur fires or other inhalational exposures. Among 49 who underwent open lung biopsy, 38 had constrictive bronchiolitis, an extremely rare condition in otherwise healthy [... read more]

After 25 years of declines in coal workers’ pneumoconiosis (thanks to federal regulation of tolerable concentrations of coal dust and radiographic surveillance of miners), CWP and progressive massive fibrosis have been on the upswing since 2001, killing or disabling dozens of relatively young miners. Wade et al describe the trend in a cohort of 138 [... read more]
Pulmonary rehabilitation, realities in clinical practice. Birnbaum S, CHEST 2011;139:1498-1502. Having trouble finding a pulmonary rehab program to refer your COPD patient into? That may be because in 2011, according to Mr. Birnbaum, Medicare paid outpatient centers $28 per rehabilitation session, per patient.
Due to its characteristic brain tumors causing intellectual delay and seizures, TSC-LAM usually presents in childhood. Seibert et al report a series of 79 adult women with TSC-LAM, 45 of whom were diagnosed in adulthood. 15 did not meet diagnostic criteria until after age 18. Ann Intern Med 2011;154:806-813.
Lung vasculitis and alveolar hemorrhage. Ten articles in 103 pages. Semin Resp Crit Care Med 2011;32:243-346. Review.
Taveira-DaSilva reports an observational series of 19 women treated with sirolimus for lymphangioleiomyomatosis. Of 12 women with chylous pleural effusions, most had a large improvement or resolution in their effusions. Ann Intern Med 2011;154:797-805. In a randomized trial of 89 LAM patients published in NEJM March 2011, sirolimus reduced decline of lung function.

Song et al retrospectively reviewed 461 cases of IPF (269 biopsy-proven) in Korea. More than a third of patients were hospitalized for respiratory deteriorations over a 2-year period. About half the deteriorations were attributed to acute exacerbations of IPF, with most of the rest attributed to infections (half the patients had BAL and/or ET aspirates [... read more]
McCormack et al randomized 89 women with lymphangioleiomyomatosis to receive 2 mg rapamycin or placebo daily for 12 months, followed by 12 months of drug-free observation. Women receiving sirolimus had stable lung function on spirometry, fewer symptoms, fewer “respiratory events,” and better quality of life during the treatment period. This was tempered by GI, dermatologic, [... read more]
