Bladder and bowel dysfunction affect quality of life. A cross sectional study of 60 patients with aquaporin-4 antibody positive Neuromyelitis Optica spectrum disorder

- Extensive myelitis associated in NMO causes significant bladder and bowel problems.
- Affects physical, psychological and social well-being lowering quality of life.
- Feeling worn out and restrictions upon travel were main effect of urinary symptoms.
- Early identification and management by multi-disciplinary healthcare is essential.

BackgroundTransverse myelitis (TM) associated with Neuromyelitis Optica (NMO) can be severe and is well known to reduce mobility early in the disease. However the burden of bladder and bowel dysfunction is unknown and overlooked. We studied the frequency of bladder and bowel dysfunction and their impact on quality of life.MethodsA cross-sectional study of 60 patients who had AQP4-IgG positive NMO associated TM was performed using the Bladder Control Scale, Lower Urinary Tract Quality of Life, Bowel Control Scale and Neurogenic Bowel Score, Short-Form-36 Health Survey and EDSS. The relationships between the variables were analysed with multiple linear regression.ResultsFifty women and 10 men participated. 78% (47/60) patients reported bladder symptoms and a similar number reported bowel problems. 87% (52/60) patients reported either bladder or bowel dysfunction. 65% (39/60) developed residual symptoms after the first episode of myelitis and the remaining by the second episode. Both bladder and bowel dysfunction reduced quality of life and required modification of lifestyle in 83% (39/47) and 70% (33/47) respectively.ConclusionBladder and bowel dysfunction is very common in NMO associated myelitis developing early in the disease and significantly affects quality of life.
