A single-centre experience of post-renal transplant lymphoproliferative disorder

Post-transplant lymphoproliferative disorder (PTLD) complicates 1 to 10% of all transplantations. Previous clinicopathological studies of PTLD have been limited by small numbers, short follow-up times, outdated data, heterogeneity of pooled solid-organ transplant results, and selective inclusion of early-onset disease. We therefore undertake here a retrospective analysis and identify all cases of PTLD that complicated renal transplantation at the Princess Alexandra Hospital between 30 June 1969 and 31 May 2001. Tumour samples were subsequently retrieved for pathological review and for Epstein-Barr virus-encoded RNA in situ hybridisation (EBER-ISH). Of 2,030 renal transplantation patients, 29 (1.4%) developed PTLD after a median period of 0.5 years (range 0.1 to 23.3 years). PTLD patients were more likely to have received cyclosporine (76% versus 62%, P

Functional memory CD8+ T cells can be generated in vivo without evident T help

Synthetic cytotoxic T cell (CTL) epitope peptides provide an effective and safe means of vaccination against cancers and viruses, as these peptides can induce specific CD8+ effector T cells in vivo. However, the effector CD8+ T cells induced by the minimal CTL epitope peptides do not last past about 3 weeks after the induction and no functional memory CD8+ T cells are generated. It is held that simultaneous induction of CD4+ T cells by incorporating peptides containing T-helper epitopes in the vaccine at the time of primary vaccination are necessary for the induction of long-lived functional memory CD8+ T cells. We now report that, surprisingly, incorporation of medium length (>20 AA) peptides devoid of detectable T-helper epitopes in a minimal CTL epitope-based vaccine can also induce long-lasting! functional rumour antigen specific memory CD8+ T cells that are capable of promoting protection against tumour challenge. This observation may have implications for the formulation of therapeutic anti-cancer and anti-virus peptide vaccines where a strong induction of CD4 T help would be undesirable.

Phase 1 study of HPV16-specific immunotherapy with E6E7 fusion protein and ISCOMATRIX (TM) adjuvant in women with cervical intraepithelial neoplasia

Purpose: Persistent infection of cervical epithelium with high risk human papillomavirus (HPV) results in cervical intraepithelial neoplasia (CIN) from which squamous cancer of the cervix can arise. A study was undertaken to evaluate the safety and immunogenicity of an HPV 16 immunotherapeutic consisting of a mixture of HPV16 E6E7 fusion protein and ISCOMATRIX(TM) adjuvant (HPV16 Immunotherapeutic) for patients with CIN. Experimental design: Patients with CIN (n = 3 1) were recruited to a randomised blinded placebo controlled dose ranging study of immunotherapy. Results: Immunotherapy was well tolerated. Immunised subjects developed HPV16 E6E7 specific immunity. Antibody, delayed type hypersensitivity, in vitro cytokine release, and CD8 T cell responses to E6 and E7 proteins were each significantly greater in the immunised subjects than in placebo recipients. Loss of HPV16 DNA from the cervix was observed in some vaccine and placebo recipients. Conclusions : The HPV16 Immunotherapeutic comprising HPV16E6E7 fusion protein and ISCOMATRIX(TM) adjuvant is safe and induces vaccine antigen specific cell mediated immunity. (C) 2004 Elsevier Ltd.

ISCOMATRIX (TM) adjuvant: An adjuvant suitable for use in anticancer vaccines

Human Papillomavirus type 16 (HPV16) E6 and E7 oncoproteins are associated with cervical cancer development and progression and can therefore be used as target antigens for cancer immunotherapy. In this study we evaluated the immunogenicity in mice, of different vaccine formulations using recombinant HPV16 derived E6E7 or E7GST fusion proteins. When co-administered with ISCOMATRIX(TM) adjuvant, these E6E7 proteins consistently induced E7 specific CTL, in vivo tumor protection, antibody and DTH responses. ISCOMATRIX(TM) adjuvant has been developed for use in the formulation of novel human vaccines and has been evaluated for safety and toxicity in human trials. A formulation containing aluminum hydroxide (Al(OH)(3)) gave a lesser degree of E7 specific antibody, and no local E7 specific CTL response but similar DTH and tumor protection. These findings demonstrate the potential of ISCOMATRIX(TM) adjuvant to stimulate both cellular and humoral immune responses to endogenously processed target antigens, and hence is the preferred adjuvant when CTL responses are desirable.
