Myasthenia gravis: steroid-induced effects on lymphocyte subpopulations in myasthenia gravis. 1977

L Hammarström, and E Smith

Lymphocyte subpopulations from patients with myasthenia gravis were evaluated during chronic steroid therapy. A marked lymphocytopenia (10-70%) was initially (day 3-21) noticed as well as a preferential depletion of thymus-derived cells which paralleled the clinical deterioration. Thus there was a relative increase in B cells, although their absolute number remained rather constant. These changes were reverted within 2-4 weeks in spite of continuous treatment. These findings are compatible with a release of myasthenic factors (anti-acetylcholine receptor antibodies?) during the initial steroid-induced cell damage, the long-term beneficial effects being due to loss or suppression of autoreactive helper t cells.

D009157 Myasthenia Gravis A disorder of neuromuscular transmission characterized by fatigable weakness of cranial and skeletal muscles with elevated titers of ACETYLCHOLINE RECEPTORS or muscle-specific receptor tyrosine kinase (MuSK) autoantibodies. Clinical manifestations may include ocular muscle weakness (fluctuating, asymmetric, external ophthalmoplegia; diplopia; ptosis; and weakness of eye closure) and extraocular fatigable weakness of facial, bulbar, respiratory, and proximal limb muscles. The disease may remain limited to the ocular muscles (ocular myasthenia). THYMOMA is commonly associated with this condition.

D011950 Receptors, Cholinergic Cell surface proteins that bind acetylcholine with high affinity and trigger intracellular changes influencing the behavior of cells. Cholinergic receptors are divided into two major classes, muscarinic and nicotinic, based originally on their affinity for nicotine and muscarine. Each group is further subdivided based on pharmacology, location, mode of action, and/or molecular biology.

D003348 Cortisone A naturally occurring glucocorticoid that has been used in replacement therapy for ADRENAL INSUFFICIENCY and as an anti-inflammatory agent. Cortisone itself is inactive; it is converted in the liver to the active metabolite HYDROCORTISONE.
