The level of serum KL-6 antigen has been reported to be a sensitive indicator of various interstitial pneumonitis, but in patients with hematological malignancies who were accompanied by infective interstitial pneumonitis like Pneumocystis carinii or cytomegalovirus (CMV) pneumonia, it is still unknown whether serum KL-6 level is useful as a good marker for the diagnosis or disease activity. In this study, the serum levels of KL-6 and soluble intercellular adhesion molecule 1 (sICAM-1) were evaluated in five patients with malignant lymphoma or adult T-cell leukemia. Serum KL-6 and sICAM-1 levels at the time of diagnosis of P. carinii or CMV pneumonia were 1220+/-323 U/ml (mean+/-SD) and 1246+/-485 ng/ml, respectively. These levels were apparently high, when compared with standard value of serum KL-6 (<520 U/ml) and that of sICAM-1 (115-306 ng/ml). In patients without P. carinii or CMV pneumonia, who had hematological malignancies or AIDS, serum level of KL-6 was not high (299+/-122 U/ml), but sICAM-1 was high (651+/-495 ng/ml) because of the elevation of sICAM-1 in four of five cases. These findings suggest that, in patients with hematological malignancies, serum level of KL-6 antigen rather than sICAM-1 may be useful in the evaluation of CMV or P. carinii pneumonia.
