I read with interest a case report of Satoyoshi syndrome by Ashalatha et al.[1] The similarity with a 'jerking stiff-man syndrome' -a variant of stiff-man syndrome (SMS) is striking. Distal limb involvement, myoclonic jerking, board-like muscles, stimulus-evoked spasms, endocrinopathies, vitiligo, pernicious anemia and sicca syndrome can also be seen in jerking SMS.[2] Continuous motor unit activity (CMUA) is necessary to diagnose this variant but can sometimes be elusive and manifest only in the paraspinal muscles.[3] Earlier this year, anti-GAD antibodies were described with Satoyoshi syndrome.[4] This validates the auto-immune nature of this disorder and suggests that it might be a variant of stiff-man syndrome. In both cases, a partial response to immunomodulating agents such as immuno-globulin or high dose steroids may be seen. I wonder if anti-GAD antibodies could be tested in the described case as well.
