ABSTRACT
The frequency of oligoclonal bands (OCB) restricted to the cerebrospinal fluid (CSF) from patients with multiple sclerosis (MS) varies widely in different populations. The objective of this study was to determine the frequency of these OCB in a group of MS patients in the city of São Paulo. Techniques used to detect OCB consisted of isoelectric focusing followed by immunoblotting. Oligoclonal bands were found in 49 (54.4 percent) out of 90 patients with clinically definite MS; in (31.2 percent) of the 16 patients with clinically isolated syndrome; in 7 (17.9 percent) of 39 patients with inflammatory disorders of the central nervous system (IDCNS), and in none of the individuals with no neurological condition (control group). The specificity of the method was 100 percent when compared to the control group and 82.1 percent when compared to the IDCNS group. These results suggest that the frequency of CSF OCB is much lower in Brazilian MS patients from São Paulo city than that reported in MS series from Caucasian populations.
RESUMO
A frequência da detecção de bandas oligoclonais (BOC) restritas ao líquido cerebrorraquidiano (LCR) em pacientes com esclerose múltipla (EM) varia amplamente em diferentes populações. O objetivo deste estudo foi determinar a frequência destas BOC em pacientes com EM em amostra de população da cidade de São Paulo. A técnica utilizada para a detecção das BOC foi a focalização isoelétrica, seguida do immunoblotting. BOC foram detectadas em 49 (54,4 por cento) de 90 pacientes com EM clinicamente definida; em 5 (31,2 por cento) de 16 pacientes com síndrome clínica isolada; em 7 (17,9 por cento) de 30 pacientes com doenças inflamatórias do sistema nervoso central (DISNC); e em nenhum indivíduo sem doença neurológica. A especificidade do método foi 100 por cento quando comparada ao grupo controle e 82,1 por cento quando comparada ao grupo de DISNC. Estes resultados sugerem que a freqüência de BOC no LCR é mais baixa em pacientes da cidade de São Paulo portadores de EM do que aquelas descritas em populações caucasianas.
