RESUMEN

<p><b>BACKGROUND</b>High expressions of galectin-3 were identified recently in the end stage of amyotrophic lateral sclerosis (ALS) patients, which suggested that immune reactivity and inflammatory mechanisms might play an important role in the pathogenesis of ALS. The purpose of this study was to investigate plasma galectin-3 levels in different groups and stages of ALS patients and the association with related clinical characteristics.</p><p><b>METHODS</b>A total of 51 patients with ALS and 60 normal controls (NCs) were recruited in this study. Plasma galectin-3 levels were determined using the enzyme-linked immunosorbent assay. Patients with ALS were divided into several groups according to their clinical characteristics: gender, type of disease onset, duration of disease, and clinical conditions of disease. Statistical analyses of the differences of galectin-3 levels between groups and the association with the clinical characteristics of disease were performed.</p><p><b>RESULTS</b>As compared with the NCs (201.64 [22.35-401.63] ng/ml), plasma galectin-3 levels were significantly elevated in the patients with duration >12 months (341.17 [69.12-859.22] ng/ml, P< 0.05), and the patients with limb onset of disease (254.14 [69.12-859.22] ng/ml, P< 0.05); however, no difference was found in the patients with duration ≤12 months (250.62 [109.77-334.92] ng/ml, P > 0.05), and the patients with bulbar onset of disease (251.79 [109.20-404.76] ng/ml, P > 0.05). In addition, galectin-3 levels were significantly increased in the female patients (263.27 [123.32-859.22] ng/ml, P< 0.05) while no difference was found in the male patients (220.39 [69.12-748.73] ng/ml, P > 0.05). The further statistical analyses showed that plasma galectin-3 levels were positively correlated with the duration of disease (r = 0.293, P = 0.037).</p><p><b>CONCLUSIONS</b>Plasma galectin-3 levels were significantly increased in ALS patients with limb onset of disease, especially in ALS female patients, and positively correlated with the duration of disease, which suggested that plasma galectin-3 might be an interesting and useful factor associated with ALS.</p>

RESUMEN

<p><b>OBJECTIVE</b>To assess the value of cerebral spinal fluid (CSF) and serum myelin basic protein (MBP) levels in the diagnosis of multiple sclerosis (MS).</p><p><b>METHODS</b>Enzyme-linked immunosorbent assay was used to detect the CSF and serum levels of MBP in patients with MS (n=45), patients with Guillain-Barre syndrome (GBS) (n=36) and control subjects (control) (n=33). The sensitivity and specificity of MBP in CSF and serum in the diagnosis of MS were evaluated using the receiver-operating characteristic (ROC) curves.</p><p><b>RESULTS</b>The MBP levels in CSF and serum both increased significantly in MS group as compared with those in GBS (P<0.01) and control groups (P<0.01). The area under the curve (AUC) of the ROC curve of MBP in CSF was 0.853-/+0.037 for MS diagnosis, and with the optimal cut-off value of 0.87 pg/ml, CSF MBP showed a diagnostic sensitivity of 83.7% and specificity of 78.3%. The AUC of the ROC curve of serum MBP was 0.761-/+0.046, and the optimal cut-off value of 0.25 pg/ml resulted in a diagnostic sensitivity of 62.8% and specificity of 73.9%. No statistically significant difference was found between the two AUCs (P>0.05).</p><p><b>CONCLUSION</b>Evaluation of CSF and serum MBP levels allows accurate diagnosis of MS, and MBP level in the CSF has greater diagnostic sensitivity than serum MBP. The combination of both CSF and serum MBP levels may serve as a sensitive index for the diagnosis of MS.</p>
