title: Evaluation of procollagen-III peptide as a marker for veno-occlusive disease after bone marrow transplantation.
abstract: Procollagen-III peptide (PIIIP) has been suggested as a marker for hepatic veno-occlusive disease (VOD) after bone marrow transplantation (BMT). Using the RIA-gnost PIIIP assay, we examined frozen plasma samples from three groups of patients. The groups included (A) four patients with clinically proven VOD, (B) nine patients with remarkably uneventful post-BMT courses, and (C) patients with either early complications other than VOD or pulmonary fibrosis in their later course. In group A, PIIIP levels increased parallel to the clinical course, with maximum values of 2.7-5.5 units/ml. In group B, values did not exceed 1.4 units/ml. In group C, higher values were occasionally observed. In one patient with early relapse of a lymphoma PIIIP peaks correlated with episodes of fever and graft versus host disease (GVHD). In another patient mild VOD seems possible retrospectively. The highest levels ( > 15 units/ml) occurred in one patient with ileus. Several patients with interstitial pneumonia (IP), adult respiratory distress syndrome (ARDS), or lung fibrosis showed increases in PIIIP levels corresponding to the clinical course; most of these events occurred later than day 30 after BMT. One patient with severe GVHD of the liver showed a maximum of only 1.4 units/ml. PIIIP elevation correlated with clinical VOD and may help to differentiate it from hepatic GVHD. In the presence of other complications (pulmonary, gastrointestinal), some caution in interpreting the results may be advisable.
