Concentrations and ex vivo production of interleukin‐1β (IL‐1β), tumour necrosis factor‐α (TNF), interleukin‐6 (IL‐6), interleukin‐1 receptor antagonist (IL‐1RA) and TNF soluble receptors were followed in bronchoalveolar lavage (BAL) fluid and blood from 10 HIV‐seronegative patients with Pneumocystis carinii pneumonia (PCP) and compared with values found in healthy volunteers. During the acute phase of PCP, TNF but not IL‐6 or IL‐1β was detectable in BAL fluid. At that time, plasma concentrations of the proinflammatory cytokines were low, whereas plasma concentrations of the anti‐inflammatory cytokines were high. The ex vivo production capacity of proinflammatory cytokines was suppressed in the acute phase, in the blood as well as at the site of infection. During convalescence the production capacity of the blood cells normalized. The IL‐1RA production capacity of the alveolar cells was also suppressed in the acute phase, but preserved in blood cells.
