Beta-2-microglobulin was determined in 147 patients admitted to hospital because of suspicion of CNS disease. Patients with meningism were chosen as control group. The concentration of beta-2-microglobulin in the spinal fluid of control patients was correlated with age. Reference values for 0-40 years were 0.34-1.58 mg/l. Above 40 years of age the values were 0.46-3.14 mg/l. CSF beta-2-microglobulin levels of patients with meningism, aseptic and bacterial meningitis overlap too much to be relevant in distinguishing between these entities. Five patients with herpes simplex encephalitis had markedly elevated levels ranging from 4.4 to 9.0 mg/l. Ten patients with herpes zoster-associated encephalitis had values from 1.1 to 6.1 mg/l. In the patient groups with CNS infections, the ratio of serum to spinal fluid beta-2-microglobulin was significantly more frequently less than 1 as compared with the meningism group, indicating intrathecal production of the protein. Further studies on the clinical relevance of CSF beta-2-microglobulin in the diagnosis of encephalitis seem warranted.
