Abstract:

Although serum Krebs von den Lungen-6 (KL-6) levels are reported to increase in pulmonary tuberculosis (PTB) patients according to disease activity, the relationship between serum KL-6 levels and prognosis remains unclear. In this study, we prospectively examined serum KL-6 levels in 188 PTB patients and assessed 60-day mortality. Univariate and multivariate logistic regression analysis demonstrated that serum KL-6 levels were not significantly associated with prognosis. For receiver operating characteristic analysis, the area under the curve had low accuracy for predicting mortality. These findings indicate that serum KL-6 levels do not perform adequately for use as a prognostic marker in patients with PTB.
