title: Increased frequency of chromosome aberrations in long-term cultured cerebrospinal fluid lymphocytes of patients with multiple sclerosis.
abstract: A method employing long-term lymphocyte culturing was developed to study chromosome aberrations in samples with very few cells. It was used to examine lymphocytes from the cerebrospinal fluid (CSF) and peripheral blood (PB) in 23 patients with clinically definite multiple sclerosis (MS), nine patients with other neurological diseases (OND), and eight healthy individuals. MS patients had significantly more aberrations in CSF lymphocytes than in PB lymphocytes (6.4 vs 4.1; P = 0.003). In contrast, no such difference was noted among patients with OND (3.8 vs. 3.7; P = 0.89) or healthy controls (3.6 vs 3.5; P = 0.90). CSF lymphocytes from MS patients had more aberrations than CSF lymphocytes from healthy controls (P = 0.012), but there was no difference between PB lymphocytes from MS patients and controls (P = 0.58). The patients with OND were similar to healthy controls both in CSF (3.8 vs 3.6; P = 0.91) and PB lymphocytes (3.7 vs 3.5; P = 0.90).
