| Popis: | Effectiveness of enzyme replacement therapy (ERT) in reverting hematologic, skeletal, and visceral symptoms in Gaucher disease (GD) has been demonstrated, although, its efficacy in neurologic involvement is still debated.We evaluated the extent of neuro-cognitive dysfunction using brain stem evoked potential in GD3 patients, age-matched controls, and GD1 patients without neurological manifestations served as disease control group.Study included 56 GD (36 had type 1, 20 had type 3) under ERT. Investigations included complete blood count, beta glucosidase assay in peripheral leucocytes, plasma chitotriosidase and bone marrow examination, electroencephalography, brain stem auditory (AEP), somatosensory (SSEP) and visual evoked potentials (VEP) as well as IQ testing.Both types of GD showed significantly higher mean latency at 75 on left eye, lower PP amplitude ratio, higher latency at 75, 100, 145, lower amplitude, and higher Lat Diff LT-RT ms and Lt-Rt % compared to controls (p0.05) with no difference between both groups in other values of VEP. Both groups showed significantly prolonged latency of N 13-19 compared to controls (p0.05) with positive correlation between age and duration of therapy with parameters of SSEP (p0.01). Both groups of GD had significantly prolonged latency of the mean waves of AEP compared to controls (p0.05) with no significant difference between both groups. There was a negative correlation between age and waves II, III, I-III, I-V and threshold values of AEP. IQ level was positively correlated with AEP values. Severity scoring tool was positively correlated with AEP and SSEP values.Electrophysiological abnormalities were present in both types of GD and have been correlated to cognitive function and disease characteristics. |
