Successful treatment of stiff person syndrome with sequential use of tacrolimus.

چکیده
Stiff person syndrome (SPS) is a rare neurological disease with features of an autoimmune disease. SPS is characterised by severe progressive muscle stiffness of the spine and lower extremities with superimposed muscle spasms triggered by external stimuli such as noise, touch and emotional distress. Patients with SPS respond to high doses of muscle relaxants, such as diazepam and baclofen, several anticonvulsants, and gabapentin. Previous studies have reported that several causal treatments with corticosteroids, plasmapheresis, intravenous immunoglobulin (Ig) and new immunomodulating agents can reduce stiffness and lower sensitivity to stimuli and stress in patients with SPS. 3 Because SPS is a chronic disease, patients generally require long-term treatments, which may be effective but difficult to take for long periods. Tacrolimus (Prograf, FK506) is a macrolide molecule belonging to the same immunosuppressant class as cyclosporine. Tacrolimus has a lower molecular weight and is 100-fold more potent in inhibiting T cell proliferation than cyclosporine. It acts through inhibition of the calciumcalcineurin (CaN) pathway and exerts its immunosuppressive effect by reducing the proliferation of activated T cells. We now report the successful treatment of patients with SPS using tacrolimus as the immunosuppressive agent.

Stiff person case misdiagnosed as conversion disorder: A case report
Background: Stiff person syndrome (SPS) is a rare neurological disease resulting in stiffness and spasm of muscles. It initially affects the axial muscles and then spread to limb muscles. Emotional stress exacerbated the symptoms and signs of the disease. The pathophysiology of the disease is caused by the decreased level of the glutamic acid decarboxylase (GAD) activity due to an autoantibody ...

We reported a 27-year-old man presenting with progressive muscle rigidity and intermittent spasms for six years. The diagnosis of stiff-person syndrome was based on the clinical features and neuroelectrophysiologic findings of continuous motor unit activities. Autoantibody against glutamic acid decarboxylase in our patient was absent either in serum or in cerebrospinal fluid. The patient was su...
متن کاملStiff Person Syndrome with Good Treatment Response to Intrathecal Baclofen
Stiff person syndrome is a rare disorder affecting the musculoskeletal system due to an underlying autoimmune process. Our case describes a 36 year old female who presented with painful, distressing, intermittent muscular rigidity and a possible associated seizure disorder. The key highlight of our case is the misdiagnosis of her disease in the early stage and the successful management of stiff...
متن کاملThe use of tacrolimus in the management of minimal change disease.
Kim et al [1] showed interesting results that tacrolimus and low-dose prednisolone therapy induced complete remission rapidly and effectively in adult patients with minimal change disease (MCD). MCD has been regarded as an immunological disorder. Recent works, however, have dramatically enhanced the understanding of podocyte biology, which may be the mainstay involved in the pathogenesis of MCD...
