3 Year Follow up on ANO5 Patients

Active, not recruiting
Conditions
Limb Girdle Muscular Dystrophy
Neuromuscular Diseases
Interventions
Other: No intervention - pure observational study
Registration Number
NCT05206617
Lead Sponsor
Rigshospitalet, Denmark
Brief Summary

The aim of the study is to investigate progression in muscle affection in patients with pathogenic variants in the anoctamin 5 gene to:

1. investigate possible progression of disease over time

2. investigate good and reliable outcome measures

Detailed Description

Muscles of patients with pathogenic variants in the anoctamin 5 gene will over time be infiltrated with fat. This is especially visible on MRI and can be seen even before any symptoms appear. MRI is thus used increasingly to investigate muscle affection in neuromuscular disorders. Together with functional measurements it is possible to describe how patients are affected clinically and subclinically. There are still many things that need covering - rate of progression is undertermined and good outcome measures are still needed for future clinical trials.

Muscles of the whole body in patients with neuromuscular disorders will be investigated 3 times through a 3 year follow-up study.

Primary Outcome Measures
NameTimeMethod
Change in fat fraction during 3 years40 minutes

Change in fat fraction (%) during 3 years in muscles from the whole body measured from Dixon MRI.

Secondary Outcome Measures
NameTimeMethod
Change in quality of life during 3 years15 minutes

Change in quality of life during 3 years measured through the questionnaire SF36. 36 questions. Higher score means higher quality of life.

Change in fatigue during 3 years5 minutes

Change in fatigue during 3 years measured through the questionnaire 'fatigue severity score', FSS. 9 questions scoring from 1-7 where 7 correlates to "strongly agree". Higher score means more fatigue.

Change in balance during 3 years20 minutes

Change in balance during 3 years measured using a biosway

Change in pain and function during 3 years10 minutes

Change in pain and function in lower limbs during 3 years measured through the questionnaire 'low back pain rating scale ', LBPRS. 6 questions rated from 0-10 with 0 meaning no pain. Higher score means more pain.

Change in handgrip during 3 years10 minutes

Change in handgrip during 3 years measured using a handgrip dynamometer.

Change in motor function during 3 years30 minutes

Change in motor function during 3 years measured using the test the Motor Function Measure 32. 32 tasks to do, each task score 0-3. Higher score means better motor function.

Change in whole body muscle strenght during 3 years30 minutes

Change in muscle strenght in whole body during 3 years measured using the technique 'manual muscle testning (MMT)' and the 'manual rating scale (MRC) '

Change in muscle strenght during 3 years30 minutes

Change in muscle strenght in knee, hip and back during 3 years measured using a staionary dynamometer (a biodex dynamometer)
