may be a good marker for monitoring disease activity of interstitial pneumonia. This study was designed to ascertain the clinical significance of serum KL-6 levels in interstitial pneumonia associated with anti-neutrophil cytoplasmic antibody (ANCA)-related vasculitis. Methods. Serum KL-6 levels were determined by an enzyme-linked immunosorbent assay. Patients. We examined 20 healthy subjects, 13 patients with perinuclear (myeloperoxidase, MPO) ANCA-related vasculitis and 12 dermatomyositis (DM)/polymyositis (PM) patients as disease controls in this study. Six out of 13 patients with ANCA-related vasculitis had interstitial pneumonia. Results. Serum levels of KL-6 in ANCA-positive patients with interstitial pneumonia were significantly elevated, while they remained as low as those of healthy subjects in ANCA- positive patients without interstitial pneumonia. Similarly, KL-6 levels in sera were higher in 12 dermatomyositis/polymyositis patients with interstitial pneumonia, while they remained low in DM/PM patients without interstitial pneumonia. Moreover, the elevated serum KL-6 level was reduced during the convalescence induced by glucocorticoid therapy and reflected the disease activity of interstitial pneumonia associated with ANCA-related vasculitis. Conclusion. These data suggest that the measurement of serum KL-6 levels may be a good monitoring system for the diagnosis and follow-up of interstitial pneumonia of patients with ANCA-related vasculitis.

概要:
金沢大学附属病院神経内科<br />We report two cases of superficial siderosis (SS) of the central nervous system (CNS), which is caused

by chronic haemorrhaging into the subarachnoid space with haemosiderin deposition in the superficial portion of the CNS. Patient 1 had fluid collection in the spinal canal, which was reported as the source of the chronic bleeding. Patient 2 was bleeding from thickened dura at the level of the sacral vertebrae. Both of the patients had xanthochromic cerebrospinal fluid. We surgically repaired the sources of bleeding. Subsequently the cerebrospinal fluid (CSF) cleared and their symptoms were not aggravated for about 1 year. We measured several CSF markers of SS before and after surgery. Total tau protein (CSF-t-tau), phosphorylated tau protein (CSF-p-tau), iron (CSF-iron) and ferritin (CSF-ferritin) in the CSF were highly elevated at diagnosis. After surgery, the levels of CSF-t-tau and CSF-p-tau were markedly reduced while CSF-iron and CSF-ferritin had not decreased. It is suggested that CSF-t-tau and CSF-p-tau reflected the neural damage in SS and were useful to evaluate the effectiveness of SS therapies. © 2009 Elsevier B.V. All rights reserved.
