Pregnancy and Birth in HypoKPP

Part Two Case Studies - HypoKPP

Patient #1 Three Pregnancies:

Familial HypoKPP Symptoms began at age of 13 years with three paralytic episodes of 48-72 hour duration.

Are your symptoms worse with your menses? No

Pregnancy No 1: Age 20

Diagnosed at time of this pregnancy: Yes

Episodes consisted of minor weakness and fatigue once or twice a month. No medications during pregnancy. Maintained normal activity. Uncomplicated labour with forceps delivery of 7 lb. healthy male child three weeks short of due date.

Pregnancy and Birth in the Periodic Paralysis Patient

Part One

There is little available medical literature to guide the physician in the care of the pregnant patient who has periodic paralysis. The first part of this packet consists of abstracts and quotations drawn from current literature. But this information is limited. Because Periodic Paralysis International has a number of clients who have given birth we felt it might be helpful to survey them about their experiences. The second, third and forth parts of this packet consists of case studies of women with periodic paralysis who have given birth.

Myoclonus Survey Part 2

Description of Myoclonus

Myoclonus Survey in Periodic Paralysis Patients Part 1

Myoclonus is the sudden, involuntary jerking of a muscle or group of muscles. Myoclonic jerks may occur alone or in sequence, in a pattern or without pattern. They may occur infrequently or many times each minute. Myoclonus sometimes occurs in response to an external event or when a person attempts to move. The twitching cannot be controlled by the person experiencing it.

Paramyotonia Congenita & Paramyotonia Syndromes

Paramyotonia Congenita (PMC) is one of the periodic paralyses caused by mutations in the sodium channel. PMC causes muscle stiffness (myotonia) which is made worse by chilling or activity. Myotonia usually eases when the patients moves about, or "warms up" through physical activity. In PMC myotonia develops during activity, which is paradoxical or self-contradictory. This is where Paramyotonia Congenita gets its name, from the paradoxical nature of the myotonia.

Pain in the Periodic Paralyses

Pain Often Overlooked

Pain is an often overlooked component of the periodic paralyses. Patients who report muscle pain in association with their episodes are too often told that the periodic paralyses are not painful despite many authoritative reports to the contrary. In fact the pain which accompanies the periodic paralyses is described in some of the literature as prominent or constant.

Emergency Treatment of the Hypokalemic Paralytic Attack

First Actions:

  • Respiratory and cardiac arrest are possible.
  • Check vitals - cardiac diliatation may cause hypotension and low pulse pressure
  • Call for Cardiac Monitoring/EKG
  • Draw electrolytes to determine serum K+
  • Provide 02 - thimble may not reflect 02 saturation due to cardiac dilitation
  • Lie patient in coma position to avoid aspiration.

How to Determine What Triggers Attacks of Periodic Paralysis

What happens during an attack of Periodic Paralysis?

People with Periodic Paralysis (PP) have episodes in which their muscles become weak or paralyzed in response to variations in the amount of potassium in their blood. These variations occur during sleep, they may result from food the person has eaten, from a sudden change in a person's activity level, from rest after activity, emotional stress, from becoming chilled, or a number of other factors. Potassium levels vary all the time.

Thyrotoxic Hypokalemic Periodic Paralysis FAQ

What is Thyrotoxic Hypokalemic Periodic Paralysis?

Thyrotoxic Hyperkalemic Periodic Paralysis (TPP) is an uncommon disorder with three characteristics which occur at the same time:  

  1. too much thyroid hormone

  2. low levels of potassium in the blood (hypokalemia)

  3. muscle weakness or paralysis
