Correlation of plasma monocyte chemoattractant protein-1 (MCP-1) and monocyte inflammatory protein-1alpha (MIP-1alpha) levels with disease activity and clinical course of sarcoidosis

Clin Exp Immunol. 1998 Mar;111(3):604-10. doi: 10.1046/j.1365-2249.1998.00519.x.


MCP-1 and MIP-1alpha exhibit chemotactic activity toward macrophages/monocytes and induce the production of inflammatory cytokines affecting granuloma formation. Up-regulated expression of MCP-1 and MIP-1alpha in the affected organ of sarcoidosis has been shown; however, the relationship between their plasma levels and the clinical course of this disease has not been determined. In the present study we measured plasma MCP-1 and MIP-1alpha levels in 26 patients with active sarcoidosis by ELISA in order to assess the state of MCP-1 and MIP-1alpha in this disease. Most patients in this study (21/26) had clinical evidence of extrathoracic disease in addition to pulmonary involvement. In addition, a high proportion of patients (n = 15) showed spontaneous remission of disease, whereas five patients showed no spontaneous remission and six patients were treated with corticosteroids over the 2-year period of study. At the time of diagnosis, both plasma MCP-1 and MIP-1alpha levels in patients with active sarcoidosis were significantly higher than in the normal controls. The levels of these cytokines in patients with extrathoracic disease were compatible with those in patients without extrathoracic disease. A longitudinal evaluation of plasma MCP-1 and MIP-1alpha levels showed that the changes in both cytokines were closely related to the clinical course of sarcoidosis. These results suggest that plasma MCP-1 and MIP-1alpha may be useful parameters for monitoring the clinical course of sarcoidosis. In addition, plasma MCP-1 and MIP-1alpha may reflect subclinical evidence of extrathoracic sarcoidosis and may play a role in initiating monocyte migration into the tissue.
