AAN 2023: Muscle symptoms not always caused by granulomas

Only about half of sarcoidosis patients showing signs of muscle disease, or myopathy, have the small clumps of immune cells in their muscles that characterize sarcoidosis, a study showed. When these clumps, called granulomas, weren’t present with muscle symptoms, myopathy was most often linked to inclusion body myositis (IBM),…

Earlier moves to specialist, better therapies welcome, patients say

People with pulmonary sarcoidosis believe earlier referrals to specialists could improve the diagnostic process and call for new treatment approaches leading to a better quality of life, according to findings from a discussion with patients from six countries. They also questioned the “concept of remission” in a multiorgan disease…

LAS system may not reflect risks for lung transplant patients

The Lung Allocation Score (LAS) system, which is used to prioritize patients awaiting lung transplant, may not accurately reflect disease severity risks for people with pulmonary sarcoidosis, a new study reports. Results showed that several factors accounted for in the LAS remain significant predictors of mortality for patients on…

Abnormal activation of immune cells, fibroblasts seen in granulomas

Researchers have uncovered a network of abnormally activated immune cells and fibroblasts — the primary active cell of connective tissue — within granulomas, the clumps of cells that cause sarcoidosis. The key players in granuloma formation include metabolically reprogrammed immune macrophages, immune T-helper (Th) cells producing pro-inflammatory molecules, and…
