Hyperkalemic Periodic Paralysis; Hypp

Description

The 2 dominantly inherited, clinically similar types of episodic flaccid generalized weakness, HOKPP and HYPP, are distinguished by the changes in serum potassium levels during paralytic attacks. An important clinical difference between the 2 entities is represented by the triggers of attacks of weakness, e.g., HYPP can be provoked by oral potassium administration, whereas this is a remedy for HOKPP. Concurrence of myotonia is found in HYPP but usually not in HOKPP patients (Jurkat-Rott et al., 2000).Jurkatt-Rott and Lehmann-Horn (2007) provided a review of the clinical features, pathogenesis, and therapeutic options for HYPP.
