Skeletal muscle sodium current is reduced in hypokalemic periodic paralysis.
H periodic paralysis (HypoPP), described a recent issue of PNAS by Jurkat-Rott and colleagues (1), has great scientific and clinical interest because its pathophysiology touches on several important properties of skeletal muscle. Besides providing the force for movement, skeletal muscle is an electrically excitable tissue and an important endocrine target organ as the largest protein store for ...
متن کاملPrimary hypokalemic periodic paralysis.
Primary hypokalemic periodic paralysis (PHPP) is a rare entity first described by Shakanowitch in 1882. Only a few cases of PHPP have been reported in Indian literature in adults(l). In children hypokalemic paralysis secondary to gastroenteritis and chronic renal disease is much more common than primary disease(2). We hereby report a case of PHPP in a child, successfully managed with acetazolam...
متن کاملHyperthyroid hypokalemic periodic paralysis
Hyperthyroid periodic paralysis (HPP) is a rare life threatening complication of hyperthyroidism commonly occurring in young Asian males but sporadically found in other races. It is characterised by hypokalemia and acute onset paraparesis with prevalence of one in one hundred thousand (1 in 100000). The symptoms resolve promptly with potassium supplementation. Nonselective beta blockers like pr...
متن کاملAcetazolamide-induced muscle weakness in hypokalemic periodic paralysis.
A 46-year-old man with hypokalemic periodic paralysis (HypoPP) and diabetes mellitus (DM) had worsened muscle weakness after acetazolamide (ACZ) treatment. During the paralytic episode, serum potassium levels were reduced, and serum chloride and insulin levels were increased. The data suggested proximal renal tubular acidosis due to ACZ. We determined arterial-venous concentrations of potassium...
متن کاملImpairment of skeletal muscle adenosine triphosphate-sensitive K+ channels in patients with hypokalemic periodic paralysis.
The adenosine triphosphate (ATP)-sensitive K+ (KATP) channel is the most abundant K+ channel active in the skeletal muscle fibers of humans and animals. In the present work, we demonstrate the involvement of the muscular KATP channel in a skeletal muscle disorder known as hypokalemic periodic paralysis (HOPP), which is caused by mutations of the dihydropyridine receptor of the Ca2+ channel. Mus...
