Abstract
A semi-quantitative ELISA, using variable surface glycoprotein of T.b. gambiense as antigen, was developed for the detection of antibodies of different immunoglobulin isotypes in serum and cerebrospinal fluid of sleeping sickness patients. Using the assay, the antibody profiles of paired serum and cerebrospinal fluid samples of 28 patients have been studied. Total concentrations of various Ig isotypes were determined as well. In serum and cerebrospinal fluid a drastic increase in IgG, basically IgG1, as a ell as in IgM levels was observed. The concentration of IgA remained relatively normal. The antitrypanosomal antibodies detected in serum and cerebrospinal fluid were mainly of the IgG (IgG1 and IgG3) and IgM isotypes. Measurement of immunoglobulin and trypanosome specific antibody concentrations in serum and CSF allows calculation of intrathecal antibody synthesis and is a possible tool for determining the clinical stage of sleeping sickness.
