Serum immunoglobulins in brain tumours and lumbar disc diseases.

Changes of serum immunoglobulin (Ig) concentrations may occur in both brain tumours and lumbar disc diseases (LDD). The purpose of this study was to investigate the changes of pre- and post-operative serum Ig levels in brain tumours and LDDs. Serum IgG, IgA and IgM levels were measured in 127 patients with brain tumour, 100 patients with LDD and 20 healthy subjects without neurological disease.
