In order to evaluate the S-100 concentration in cerebrospinal fluid from subjects with nonischemic brain damage, a total of 33 samples were analyzed: 11 from subjects in whom no organic disease could be found; 14 from patients with a diagnosis of lymphocytic or bacterial-fungal meningitis, and 8 from patients with acute lymphatic leukemia but no demonstrable signs of meningeal involvement. In all cases, the subjects considered had no previous history of melanoma or ischemic brain damage. The mean levels +/- SEM found for each study group were 1.00 +/- 0.11, 1.67 +/- 0.23 and 1.17 +/- 0.14 microg/l, respectively. Significant differences appeared between the groups when applying the Kruskal-Wallis nonparametric test (p = 0.035). The highest levels were found in the meningitis group and were significantly different from those of the control group (p = 0.015). No significant differences were found with regard to age or sex. Based on the pathophysiology of meningitis and on previous studies, the results suggest the existence of brain damage caused by an infection as a possible cause of increased S-100 levels.
