J. Killestein et al., TNF alpha production by CD4(+) T cells predicts long-term increase in lesion load on MRI in MS, NEUROLOGY, 57(6), 2001, pp. 1129-1131
Reliable laboratory prognostic factors for MS are still lacking. The predic
tive value of markers of T-cell activation for long-term disease progressio
n was investigated. Flow cytometry measurements were correlated to changes
in Expanded Disability Status Scale and MR T2 lesion load over 36 months in
14 patients with secondary progressive MS, A correlation was found between
the percentage of tumor necrosis factor-a-producing CD4(+) T cells at base
line and the change in T2 lesion load during 3-year follow-up (r = 0.79, ad
justed r(2) = 0.59, p = 0.001).
