Sarcoidosis-associated lung bleeding may be more common than known

A lung bleeding condition called diffuse alveolar hemorrhage (DAH) may develop secondary to sarcoidosis more frequently than previously reported, a small study suggests. Considering the frequency of DAH associated with sarcoidosis reported in the study, “it is essential to consider sarcoidosis in the differential diagnosis of immune-mediated DAH,” the researchers…

Sleep Apnea a Potential Protective Factor Against Sarcoidosis: Study

The chance of developing sarcoidosis is nearly halved in those with obstructive sleep apnea (OSA), a sleeping disorder wherein breathing slows or stops repeatedly and for short times during sleep, according to a large study involving U.S. veterans. The findings point to OSA as a protective factor for sarcoidosis.

Worse Lung Function, Higher BMI Linked to Lower Quality of Life

Poorer lung function and a higher body mass index (BMI), a measure indicating obesity, are significantly associated with a lower self-reported quality of life in people with sarcoidosis, a German study found. Of note, the tool used to assess quality of life — called the King’s Sarcoidosis Questionnaire or…

Obesity May Increase Risk of Sarcoidosis, While Smoking Linked to Slightly Lower Risk

Obesity is linked to an increased risk of sarcoidosis, while smoking was associated with a lower risk, according to a study reviewing medical records of nearly 350 patients. Although the study, “Smoking, obesity and risk of sarcoidosis: A population-based nested case-control study,” published in the journal…
