 AB    OBJECTIVE: Determination of the correlation of cellular and serological
       parameters including sICAM 1 by long term analysis from HIV positive non
       progressors versus progressors to AIDS. METHODS: 44 patients were
       studied at 512 visits (mean: 11), 15 patients developed AIDS within the
       observation period (1-73 months, mean 26) (progr.), 29 remained stable
       (non progr.). Parameters measured: ELISA: sICAM 1, beta 2-microglobulin
       (beta 2m), serum neopterin; flow cytometry: CD4+, CD8+38+, CD3+HLADR+.
       Statistics: Comparison of parameters at enrollment, during observation
       period and at the end of the follow up (Wilcoxon, Mann-Whitney),
       rankcorrelation of sICAM 1 with all parameters (Spearman). RESULTS:
       sICAM 1 displayed significant correlation with beta 2m (p < 0.01) and
       CD8+38+ (p < 0.001). Comparison of the initial visit (progr. vs. non
       progr.) showed differences only within the CD4+ (p < 0.01) and the
       CD8+38+ (p < 0.05) cells. Long term observations of non progr. showed
       distinct changes of CD8+38+ (p < 0.05), whereas the other parameters
       remained stable. Observation of progr. demonstrated clear shifts of all
       parameters. CONCLUSIONS: Among the growing number of cellular and
       serological factors, currently investigated for their predictive value
       in the natural course of HIV-infection, low CD4+ numbers and high
       CD8+38+ values seem to have the most importance. The definite value of
       sICAM 1, beeing enhanced and correlating well to beta 2m and CD8+38+,
       for the prediction of the clinical course is not yet clear.
