OBJECTIVE To examine in vivo levels of BAFF (B-cell activating factor of the tumor necrosis factor family) and APRIL (a proliferation-inducing ligand) in both the cerebrospinal fluid (CSF) and serum of 30 naïve MS patients and 79 subjects affected by acute or chronic inflammatory or non-inflammatory neurological diseases. METHODS Case-control study. RESULTS No difference among groups was evidenced in serum BAFF or APRIL levels. By contrast, CSF levels of BAFF in MS (mean 144.3 pg/ml+/-141.2), although not significantly different from those observed in NIND (164.2 pg/ml+/-92.0), acute peripheral OIND (243.1 pg/ml+/-139.0) or chronic OIND (240.2 pg/ml+/-122.5), were significantly higher in acute central OIND patients (1274.0 pg/ml+/-803.8; p<0.001 vs. all groups). Similarly, CSF APRIL levels in MS (1541.0 pg/ml+/-1071.0), NIND (2629.0 pg/ml+/-1669.0), acute peripheral OIND (2834.0 pg/ml+/-1118.) or chronic OIND (2764.0 pg/ml+/-659.7) were not significantly different, while they were significantly higher in acute central OIND (6218.0 pg/ml+/-3790.0; p<0.001 vs. MS and NIND; and p<0.05 vs. acute peripheral OIND). CONCLUSIONS Our results strongly suggest that further investigation is warranted to elucidate the role of BAFF and APRIL in MS and that serum levels of BAFF and APRIL do not reflect CSF levels.

D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D009103 Multiple Sclerosis An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur.

D011237 Predictive Value of Tests In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
