Abstract Cytokines are involved in the mediation and regulation of immunity, inflammation, and haematopoiesis. Secretion patterns may reflect the pathology or etiology of different diseases. In an attempt to increase our understanding of immunopathology during different forms of tuberculosis, and identify potential biological markers that may differentiate between forms of tuberculosis, we investigated the levels of 29 cytokines and KL-6 in the plasma of HIV uninfected patients with active pulmonary tuberculosis (TB) without pleural effusions and in pleural TB with and without HIV-co-infection. Healthy individuals with latent Mycobacterium tuberculosis infection and patients with non-TB pleural effusions were used as controls, We showed that pleural TB patients had increased levels of markers associated with systemic inflammation compared to pulmonary TB (EGF, G-CSF, IL-1beta IL-6, IL-8, IL-10, MCP-1, MIP-1alpha, MIP-1beta, TNF-alpha and VEGF), whereas pulmonary TB patients without effusions had higher levels of factors involved in cell-mediated immunity (IL-12p40 and sCD40L). Plasma levels of cytokines may therefore contribute to biosignatures of diseases like TB but the data also highlight systemic differences between pulmonary TB, pleural TB and other form of pleural effusion diseases.
