- AB Polymorphonuclear leukocytes (PMN) are the predominant inflammatory
- cells recruited in acute lung injury. This study compares the
- concentration of interleukin-8 (IL-8) to those of GRO alpha, both of
- which are CXC chemokines, in bronchoalveolar lavage fluid (BALF) in
- three acute pathologic states: bacterial pneumonia (BPN); adult
- respiratory distress syndrome (ARDS); and Pneumocystis carinii pneumonia
- (PCP). Levels of both IL-8 and GRO alpha were below 5 pg/ml in 16
- nonsmoking volunteers who served as controls. Despite more than twice as
- many neutrophils in the BALF of the BPN group (n = 12) than in the group
- with ARDS (n = 13), both groups had similar levels of IL-8, of 569 +/-
- 120 pg/ml and 507 +/- 96 pg/ml, respectively. The GRO alpha
- concentrations in the BPN and ARDS patients were respectively 3.3 and
- 3.4 times those of IL-8, reaching 1,870 +/- 314 pg/ml for the BPN and
- 1,699 +/- 377 for the ARDS patients. In the PCP group (n = 48, 45 human
- immunodeficiency virus [HIV]-positive, 3 HIV-negative), GRO alpha levels
- (897 +/- 172 pg/ml) were sevenfold higher than IL-8 levels (123 +/- 40
- pg/ml). In all pathologic states there was a good correlation between
- GRO alpha and IL-8 (r = 0.53, p = 0.0001). GRO alpha or IL-8 both
- correlate with the absolute neutrophil number/ml when all groups were
- studied together (r = 0.52, p = 0.0001). Only in the PCP and ARDS groups
- did IL-8 correlate with the PMN number.(ABSTRACT TRUNCATED AT 250 WORDS)
