Thirty-two patients with myelomatosis (3 with a solitary plasmocytoma and 29 with multiple myeloma) and neurological complications, from a group of 110 unselected patients with myelomatous disease were recorded. Spinal cord compression was the most frequent complication seen in 12 cases. In 9 subjects, it was the presenting symptom, and in 11 cases was caused by extradural plasmocytoma of the thoracic spine. Early decompressive laminectomy was curative in 3 cases, but in the rest, delay in diagnosis resulted in only partial recovery even with radiotherapy. Of the 6 patients with nerve root involvement, radiotherapy led to full recovery in 2 of 3 cases, and laminectomy resulted in complete improvement in 2 other cases. Peripheral polyneuropathy was seen in 8 cases, 2 related to systemic amyloidosis and 6 unassociated with amyloidosis. Both forms of neuropathy shared a slow progression, independent of the course of the myeloma. Acute encephalopathy, found in 6 cases, was due to hypercalcemia and/or serum hyperviscosity, and led to a significant shortening of mean survival. One patient had third cranial nerve palsy due to the overlying lesion of the skull base, and another suffered acute bacterial meningitis.

Serum amyloid A protein (SAA), a putative precursor of the AA protein which constitutes amyloid fibrils in secondary amyloidosis, is evaluated as a sensitive acute-phase reactant in serum. At present, SAA concentration in serum is determined by latex nephelometry, but this assay cannot detect SAA in the low concentration range lower than 10 ng/ml. We have developed a sensitive enzyme immunoassay (EIA) for determining low concentrations of SAA. The assay is reproducible, reliable and requires no pretreatment of specimen prior to assay. We measured levels of SAA by this EIA in both cerebrospinal fluid (CSF) and serum of patients with suspected meningitis, measured also levels of albumin, alpha 2 macroglobulin and C-reactive protein (CRP) to investigate if these protein levels are useful for differential diagnoses of meningitis and for indicators damage of blood-CSF barrier. The SAA reference value in CSF is 3.99 +/- 1.74 ng/ml (mean +/- SD for nonmeningitis patients). The CRP concentration in CSF in bacterial meningitis was much higher than in viral meningitis, but CRP in CSF was also high in bacterial infection other than meningitis. On the other hand, SAA concentration in CSF in these patients with any meningitis are significantly higher than the reference values of SAA (p < 0.001). However, the differences in SAA concentrations among the three types (bacterial, viral and mycotic meningitis) of meningitis were not significant.
