Soluble CD30 levels in plasma and cerebrospinal fluid in multiple sclerosis, HIV infection and other nervous system diseases.
The CD30 molecule, a member of tumor necrosis factor superfamily, has been suggested to be preferentially expressed and released in soluble form by activated T cells that produce T helper 2 type (Th2) cytokines. To evaluate whether determination of soluble CD30 (sCD30) levels could have a diagnostic value in diseases associated with Th1 and Th2 cytokine involvement, we investigated sCD30 in plasma and cerebrospinal fluid (CSF) from patients with multiple sclerosis (MS), HIV infection and other nervous system diseases. There was no statistically significant difference for plasma sCD30 levels in these clinical groups. However, patients with HIV infection had higher levels of sCD30 in CSF than MS patients. The mean sCD30 values were 3 to 6 folds higher in plasma than in CSF in all patient groups. No relationships were found between sCD30 levels and different clinical variables of MS and HIV infection, except that higher plasma sCD30 levels in HIV-infected patients were found in those with higher CD4+ T cell counts (> 200 x 10(6)) compared to the group with lower cell counts. The findings indicate that determinations of plasma and CSF sCD30 levels in MS and HIV infection have limited or no value as diagnostic or prognostic indicator.
