摘要: Among 49 patients with carcinoid tumors given long term therapy (mean, 8 months; range, 3-36) human leukocyte-derived interferon-a (huLe-IFNa), hypothyroidism occurred in 5 andthyrotoxicosis 2. Antibodies against thyroid microsomal antigen and/or thyroglobulin were found 13 patients. In 7 of these, 3 whom developed hypothyroidism, the antibodies appeared aferthe start therapy. During treatment, an increase proportions circulating activated surface HLA-DR-positive T-helper and T-suppressor cells after 3-4 days, remained elevated at 6 months. Incubation T normal individuals vitro withthe huLe-IFNa preparation induced a rise cells. This effect was mimicked by recombinant IFN7 (r-IFN7), but not r-IFNa. Further, employed HLA-DR expression on tissue culture as did T-IFNY, r-IFNa, suggesting presence bioactive hu...
