Fewer thymic changes in MuSK antibody-positive than in MuSK antibody-negative MG.

In generalized myasthenia gravis (MG) patients without detectable acetylcholine receptor (AChR) antibodies (SNMG), the thymus is often reported as "normally involuted." We analyzed thymic compartments in 67 patients with generalized MG, with AChR antibodies (AChR+, n = 23), with muscle-spe...

description In generalized myasthenia gravis (MG) patients without detectable acetylcholine receptor (AChR) antibodies (SNMG), the thymus is often reported as "normally involuted." We analyzed thymic compartments in 67 patients with generalized MG, with AChR antibodies (AChR+, n = 23), with muscle-specific kinase (MuSK) antibodies (MuSK+, n = 14) or with neither (MuSK-, n = 30), and in 11 non-MG controls. Four of 14 MuSK+ thymi had rare small germinal centers, but overall they were not different from age-matched controls. However, approximately 75% MuSK- samples showed lymph node-type infiltrates similar to those in AChR+ patients, but with fewer germinal centers. These variations may explain some apparent differences in responses to thymectomy in SNMG.
