Presentation
More rarely, patients may present with a “rigid spine syndrome (RSS)”, as in other myopathic disorders. Facial and bulbar weakness are also present in LOPD patients. [ncbi.nlm.nih.gov]
In one patient, the disease presented with fatigue and an increased serum CK-level. [ojrd.biomedcentral.com]
Entire Body System
- Fatigue
It is not uncommon for patients to experience muscle aches and cramps, as well as headaches and fatigue. [pompediseasenews.com]
Decreased pulmonary function may also contribute to the level of fatigue. In conclusion, the combination of muscle aches, fatigue, exercise intolerance and/or hyperCKemia may constitute a presymptomatic stage of LOPD. [ncbi.nlm.nih.gov]
In one patient, the disease presented with fatigue and an increased serum CK-level. [ojrd.biomedcentral.com]
- Difficulty Climbing Stairs
She had difficulty climbing stairs and standing from a seated position. She had undergone evaluation that included a muscle biopsy of the left thigh at age 46 demonstrating denervation atrophy. [ncbi.nlm.nih.gov]

- Underweight
Nutrition Patients with adult Pompe disease, particularly with juvenile disease onset, are prone to underweight or even cachexia which may add to respiratory muscle dysfunction [79]. [ncbi.nlm.nih.gov]

- Dyspnea
Clinical Presentation Daytime symptoms suggestive of respiratory muscle weakness include dyspnea on exertion or rest, dyspnea on immersion in water, and reduced physical capacity. [ncbi.nlm.nih.gov]
Gastrointestinal
- Chronic Diarrhea
Recent reports have pointed out to the GI symptoms including severe chronic diarrhea, intestinal incontinence, abdominal pain, lack of appetite, early satiety and vomiting that are underevaluated in the late onset form (51). [ncbi.nlm.nih.gov]
- Fecal Incontinence
Two of the patients reported fecal incontinence while the other reported synchronous vomiting and diarrhea; however all GI symptoms were reported to be resolved within the first 6 months of ERT. [ncbi.nlm.nih.gov]
Cardiovascular
- Heart Failure
Contraindications for I/E devices, HFCWO, and IPV include emphysema, chest wall instability, uncontrolled asthma or heart failure, pneumothorax, and pneumomediastinum. Table 3 Practical recommendations for cough assistance in patients with LOPD. [ncbi.nlm.nih.gov]
- Tachycardia
Rhythm disturbances have been also reported in LOPD, especially as sinus arrhythmias, supraventricular tachycardia, Wolff-Parkinson-White syndrome or atrio-ventricular block that required pacemaker implantation (7,38). [ncbi.nlm.nih.gov]
Musculoskeletal
- Muscle Weakness
Keywords: neuromuscular disorders, Pompe disease, respiratory muscle weakness, mechanical ventilation, cough assistance 1. Introduction Empirical data on the management of respiratory muscle weakness in adults with Pompe disease are scarce. [ncbi.nlm.nih.gov]
As muscle weakness is progressive, facial muscles, muscles supporting the spine, and those involved in breathing and eating can also be affected. [pompediseasenews.com]
- Myopathy
In muscle biopsy, the abnormalities found were: type 1 and 2 fiber atrophy (2), type 1 fiber atrophy (1), type 2 fiber atrophy (4), recent and chronic denervation (3), chronic myopathy (5), active myopathy (4), chronic and active myopathy (2), and myopathy [scielo.br]

- Confusion
In our case, absence of affected male and a similarly affected daughter on family history further contributed to confusion about inheritance, leading to an erroneous working diagnosis of autosomal limb girdle dystrophy. [ncbi.nlm.nih.gov]
Urogenital

Some authors suggested that urinary incontinence is less frequent than bowel incontinence (55), whereas others (56) reported a higher number of patients with lower urinary tract symptoms (LUTS), with specific differences related to gender. [ncbi.nlm.nih.gov]

Workup
Our patients demonstrate key diagnostic features that should lead the clinician to consider adult-onset Pompe disease early in the workup of a myopathy. This is important as enzyme replacement therapy is available. [ncbi.nlm.nih.gov]
Treatment
All of the secondary and tertiary endpoints favored the treatment group, but only the MEP results reached statistical significance.18 Patients in the treatment and placebo groups had similar frequencies of adverse events, serious adverse events, and treatment-related [ncbi.nlm.nih.gov]

Prognosis
Prognosis and management While late-onset Pompe disease is incurable, levels of the acid alpha-glucosidase enzyme can be replenished with enzyme replacement therapy, generally given patients every two weeks throughout their lives. [pompediseasenews.com]
