Improvement in delayed hypersensitivity in Hodgkin's disease with transfer factor: lymphapheresis and cellular immune reactions or normal donors.

Passive transfer of delayed hypersensitivity was achieved, with normal transfer factor, in patients with Hodgkin's disease in remission. The cellular immune responses of the recipients improved. It is suggested that, in addition to specific effect the transfer factor (or factors) has a nonspecific effect causing improvement in the state of delayed hypersensitivity of the recipient in general. The average number of E-rosette T lymphocytes was 46.3% after the transfer factor treatment in Hodgkin's disease. The control patients with Hodgkin's disease, not receiving transfer factor, had a value of 37.8%. Removal of 4.9 X 10(9) to 1.08 X 10(10) lymphocytes did not diminish the delayed hypersensitivity of the donor. Side effects attributable to transfer factor were not seen.

Tuberculous brain abscess. Case report.

The authors describe a case of tuberculous cerebral abscess of the frontal lobe that developed 1 year after an episode of acute miliary tuberculosis. The development of such a lesion indicates a persistence of infection and an immunological breakdown which may partly have been due to protein malnutrition.

Atopic hypersensitivity to cis-dichlorodiammineplatinum(II) and other platinum complexes.

Allergic reaction to an antitumor agent, cis-dichlorodiammineplatinum(II) (DDP) was investigated. A 15-year-old white male with pulmonary metastases from embryonal carcinoma of testis was treated with a combination of DDP, bleomycin, and vinblastine. The dose of DDP varied from 2 to 2.25 mg/kg given i.v. He received 7 doses of DDP in 9 months. An anaphylactic reaction was seen within 3 min of the initiation of i.v. infusion of the 8th dose of DDP. The reaction was due to atopic hypersensitivity, as confirmed by an immediate wheal and flair reaction and increased histamine release from leukocytes with DDP. His serum IgE level was elevated. Neither the presence of chloride nor the amine grouping in DDP was essential for reactivity. The replacement of platinum with palladium abrogated the reactivity. There was no cross-reactivity with 3 other platinum complexes of known antitumor activity (platinum blue, platinum(II) 1,2-diaminocyclohexane malonate, and platinum(II) ethylenediamine malonate). This was also confirmed by the lack of reaction to subsequent i.v. administration of platinum(II) 1,2-diaminocyclohexane malonate (10 mg/kg) in this patient.
