AB A wide range of immunological abnormalities have been described in
renal-cell carcinoma (RCC). The only constant one was the decrease of
CD4/CD8 ratio, reversible following radical nephrectomy in the absence
of metastases. Alpha-interferon was administered with variable benefit
to patients with metastatic RCC. The aim of this study was to document
whether the treatment of patients with metastatic RCC, with unpurified
human alpha-interferon, induced any change in the number and functional
properties of peripheral blood T lymphocytes and monocytes. Fifteen
patients were included in the study; all were treated with IFN 2,000,000
IJ/24h x 15 days, with an intercycle interval of 15 days during at least
4 cycles. The immunological analyses included the percentage and
absolute number of E-rosette forming cells, CD3+, CD4+, CD8+ and CD4/CD8
ratio as well as the percentage and absolute number of monocytes and
their phagocytic index toward the yeast particles. The analyses were
done before the treatment and after the 4th cycle of the IFN therapy and
compared toward the same analyses done in 22 healthy controls. Following
IFN treatment two significant changes were noted: a decrease in CD4/CD8
ratio (mean 1.050 fall for 19% to 44%, mean 27.25% from the initial
value) as well as a marked decrease in monocyte phagocytic index (p <
0.005). These data point to either disease-related or treatment-related
decrease in the phagocytic properties of monocytes and the decrease of
CD4/CD8 ratio.
