RESUMEN
OBJECTIVE: This study aimed to develop and assess the feasibility of an online communication skills training intervention to increase cultural competence amongst oncology nurses working with individuals from minority backgrounds. METHODS: The intervention provided examples of communication strategies using vignette-based, professionally produced videos, developed through an iterative process with input from a large multidisciplinary team. Fifty-three oncology nurses completed all three questionnaires at baseline, within 2 weeks and then 3 months after accessing the programme. RESULTS: The online intervention was well received by the majority of participants, and was endorsed as clearly presented, informative, relevant and useful by more than 90% of participants. Eighty-seven percent of participants reported increased confidence in communicating with patients via an interpreter, and 93% agreed that skills they gained would be useful in providing better patient care. Participants reported significant improvements in practice while interacting with people with limited English proficiency 2 weeks and 3 months after accessing the website (X2 = 13.66, P < 0.001). CONCLUSION: This online communication training programme can now be tested for its utility in improving patient care for oncology nurses working with patients from minority backgrounds.

AIM: To characterize HIV-1 Gag p24-specific CD4 cell responses in HIV-exposed-seronegative (ES) individuals. METHODOLOGY: Twelve ES individuals, of diverse ethnicity and wild type for the CCR5 Delta-32 mutation, were identified. Controls were HIV-negative blood donors. Gag p24-specific and total Vbeta+ CD4 cells that expressed MIP-1beta, IFN-gamma and IL-2 were enumerated by intracytoplasmic cytokine staining. beta-Chemokine expression was correlated with susceptibility to R5 HIV-1 infection, as measured by polymerase chain reaction for integrated HIV-1 and by p24 enzyme-linked immunosorbent assay. RESULTS: Similar numbers of mitogen-stimulated and Vbeta+ MIP-1beta+, IFN-gamma+ and IL-2+ T cells were found in ES and HIV-negative control subjects. However, all ES subjects tested had an HIV Gag p24-specific MIP-1beta+, IFN-gamma+ and IL-2+ CD4 T-cell response that was rare in controls. p24-Specific cells of all ES but no control subjects could be expanded by in-vitro Ag/IL-2 stimulation, and when re-stimulated with an overlapping peptide series showed evidence of a broad CD4 cell memory response directed against multiple regions of Gag p24. Mitogen-stimulated ES CD4 cells were as susceptible to HIV infection as those from control subjects, but p24-specific IFN-gamma+ CD4 cells of six out of seven ES subjects tested were less susceptible to R5 HIV-1 infection than the counterpart fraction depleted of p24-specific IFN-gamma+ cells. The addition of blocking anti-beta-chemokine antibodies did not promote R5 HIV-1 infection of p24-specific IFN-gamma+ cells. CONCLUSION: Specific CD4 cell immunity, characterized by a broadly directed memory Gag-p24 CD4 cell response and reduced susceptibility of specific CD4 cells to R5 HIV-1 infection, is a likely correlate of non-transmission.

BACKGROUND: The clinical treatment of patients with HIV and adverse drug events may be enhanced by an understanding of the underlying mechanisms. About 4% of patients with HIV receiving the potent antiretroviral drug abacavir develop a hypersensitivity reaction. This idiosyncratic reaction appears to have an immunologic component that has yet to be defined. Given that the T-cell type 2 cytokine IL-4 may be overproduced by patients with allergy or other immunologic dysregulation, an index cytokine profile could help elucidate the character of a drug-specific hypersensitivity reaction. OBJECTIVE: Quantitation of the production of the type 2 IL-4 and the counterregulatory type 1 cytokine IFN-gamma in patients with abacavir-related hypersensitivity. METHODS: Intracellular cytokines were enumerated in blood T cells by flow cytometry. Subjects were grouped for evaluation as patients with a hypersensitive response after abacavir treatment, patients initiating abacavir who also were evaluated again after 1 month on abacavir, patients on abacavir for 6 months without hypersensitivity, and HIV-naive control individuals. RESULTS: There was a significant association between increased IL-4 production by CD4 and CD8 T lymphocytes and hypersensitivity reactions to abacavir. Lymphocytes from hypersensitive subjects expressed CD28 and the anti-HIV chemokine macrophage inflammatory protein 1beta with a frequency comparable with HIV-naive control cells, suggesting the possibility that the activated T cells from patients with hypersensitivity are functional. CONCLUSION: The expansion of type 0 and type 2 T cells phenotyped by IL-4 production may correlate with abacavir-associated hypersensitivity. The data suggest a cytokine bias that may facilitate B-cell differentiation and downregulate T-cell cytotoxic responses.
