CABRERA-LIMPIAS, Sergio et al. Oligoclonal bands in cerebrospinal ñuid of patients with multiple sclerosis at the Hospital Militar Central- Bogotá DC. Acta Neurol Colomb. [online]. 2012, vol.28, n.2, pp.80-84. ISSN 0120-8748.

INTRODUCTION: multiple sclerosis is the most common disabling neurological disease in youth adults. So far there is no accurate test for diagnosis. The laboratory tests have become very important because include assessment of intrathecal antibody production in the diagnosis of this disease. OBJETIVE: describe the behavior of cerebrospinal fluid oligoclonal bands in a group of patients MATERIAL AND METHODS: a descriptive case series, with the population of MS patients currently receiving specific treatment in the Hospital Militar Central in Bogota. The absolute frequencies and measures of central tendency of the variables studied were calculated. RESULTS: among the population described there are 26 patients with MS, with a mean age of 43 years old (SD +/- 8.542). 75.1% (19) were females and 26.9% (7) male. 50% (13) of patients had positive oligoclonal bands.. CONCLUSION: with a standardized technique for determining oligoclonal bands in cerebrospinal fluid, as the high-resolution agarose gel electrophoresis the authors obtained similar results as reported in the international literature. It should make all efforts to introduce the detection of BO with the internationally recommended technique named "isoelectric focusing", who simultaneously compared serum and cerebrospinal fluid, that can get a great sensitivity and a high negative predictive value.
