Infants have the most severe form of Pompe disease known as ‘Infantile Onset‘, and can develop symptoms anytime within the first twenty four months of life. These can include the following:
Poor weight gain
The ‘infantile’ form of Pompe Disease will progress very quickly and, without treatment, these babies may not live longer than twelve months.
‘Juvenile Onset‘ Pompe disease also has the potential to progresses quickly and requires urgent treatment. Juvenile Pompe disease presents anytime between the age of 2 years to 18 years.
‘Adult Onset‘ Pompe disease is the result of a partial deficiency of the enzyme acid alpha glucosidase. If a patients symptoms present after 18 years of age they are considered to have ‘adult onset’ Pompe disease.
Symptoms for juvenile & adult onset Pompe disease will vary from patient to patient and may include the following:
Progressive muscle weaknessss
Walking with a distinct leaning-back (lordosis) and, or a hip swinging gait
Problems with walking
Unable to run
Poor balance and often falling for no apparent reason
Struggling, or being unable to climb steps or stairs, even with the support of a hand rail
Struggling to rise from a seated position
Struggle to straighten up from a bent-over position
Difficulty rolling over when in bed
Difficulty in raising arms, as in combing hair or hanging washing on the line
Struggling to get into, or out of, a car
Difficulties with eating
Shortness of breath
Restlessness in sleep and waking up many times through the night
Waking with headaches
The level of progression is different for each adult onset patient, however the average life expectancy for a patient not treated is 55 years of age (Orphanet Journal of Rare Disease 2011 6:34). Treatment for Pompe disease for all Australians is government funded subject to treatment guidelines.
