title: [Serum soluble interleukin-2 receptor in patients with pulmonary mycobacterial diseases].
abstract: Serum soluble interleukin-2 receptor (sIL-2R) levels were measured in patients with untreated pulmonary tuberculosis (24 cases), patients with multidrug-resistant intractable pulmonary tuberculosis (7 cases) and patients with pulmonary non-tuberculous mycobacteriosis (27 cases). Serum sIL-2R levels were elevated in patients with pulmonary mycobacterial diseases and were elevated in untreated pulmonary tuberculosis patients than in other patients. In patients with new tuberculosis, serum sIL-2R levels were higher in patients with extensive lesions. Serum sIL-2R level showed significant positive correlation with serum C-reactive protein level and erythrocyte sedimentation rate, and significant negative correlation with serum albumin level. In patients with intractable tuberculosis and patients with non-tuberculous mycobacteriosis, serum sIL-2R levels were lower than in patients with new tuberculosis. Even in patients with extensive lesions, serum sIL-2R levels were not elevated. Lower levels of serum sIL-2R, marker of immunocompetent cell activity, suggested that immunocompetent cell activity was suppressed in intractable tuberculosis and in non-tuberculous mycobacteriosis.
