Abstract/OtherAbstract:
OBJECTIVE: To measure urinary nerve growth factor (uNGF, essential in nerve growth and regeneration) levels in patients with a cerebrovascular accident (CVA), to determine whether uNGF could be a biomarker for predicting the neurological deficits in CVA, as the level of uNGF increases in patients with idiopathic detrusor overactivity (DO) and incontinence. PATIENTS, SUBJECTS AND METHODS: uNGF levels were measured using an enzyme-linked immunosorbent assay in normal subjects and patients with CVA and different severities of neurological impairment. Total uNGF levels were normalized to the concentration of urinary creatinine (uNGF/Cr). RESULTS: The median (interquartile range) uNGF/Cr levels were significantly higher in patients, at 0.13 (0-1.04), than in normal subjects (undetectable). The uNGF/Cr levels correlated well with the severity of neurological impairment. Patients with none/minimal neurological impairment had no detectable uNGF/Cr level, like the controls. Patients with mild/moderate impairment had levels of 0.27 (0.09-0.8) and with severe impairment level of 1.53 (0.5-3.0) (both P < 0.001), significantly greater than that of none/minimal impairment or controls. However, uNGF/Cr levels were not correlated with age, location of CVA, multiplicity of CVA, duration of CVA, urodynamic findings or the presence of urge urinary incontinence. CONCLUSIONS: The uNGF level is correlated with the severity of neurological impairment in patients with CVA but not with urge symptoms or urodynamic findings, suggesting elevated uNGF might be a result of the neurological lesion rather than lower urinary tract dysfunction in CVA.
