    Notes: We conducted a retrospective study to assess the reasons for admission to the intensive care unit, and subsequent outcome, in patients infected with the human immunodeficiency virus (HIV). Four hospitals in the south of England participated, all with specialist HIV units. Data were collected on 127 patients admitted to ICU on 133 separate occasions between June 1993 and October 1997. The mean age on admission was 38 years (range 23–60 years). Ninety-four patients (70.7%) were documented HIV-positive before admission and 36 (27%) were diagnosed HIV-positive for the first time during admission; 36.1% were admitted with Pneumocystis carinii pneumonia. Overall ICU mortality was 33%, in-hospital mortality was 56% and the eventual mortality at the end of follow-up (March 1998) was 72%. Survival was highest in those admitted with respiratory HIV-related disease or HIV-unrelated illness. Associations with poor outcome included a prior AIDS-defining illness, a CD4 cell count of less than 100 cells.ml−1 and admission secondary to sepsis.

    Restoration of Human Immunodeficiency Virus-1-Specific Responses in Patients Changing from Protease to Non-Nucleoside Reverse Transcriptase Inhibitor-Based Antiretroviral Therapy (2003)

    Notes: The effect of altering antiretroviral therapy (ART) on responses to viral, recall and human immunodeficiency virus (HIV)-1-specific recombinant antigens and interleukin-2 (IL-2) in HIV-1-infected patients was assessed. A longitudinal cohort study in eight HIV-1 infected individuals following a clinically indicated therapy change (seven for drug intolerance and one for virological failure) from protease inhibitor (PI) to non-nucleoside reverse transcriptase inhibitor (NNRTI)-based antiretroviral regimens was performed. CD4 T-cell counts, viral loads, lymphoproliferative responses, cytokine production and latent proviral deoxyribonucleic acid (DNA) were measured at baseline and at weeks 12 and 24 after therapy substitution. Following therapy-switch there was a 33% proportional increase in mitogen response (95% confidence interval (CI), 3–33%) and a 31% increase (95% CI, 15–48%) in viral and recall-antigen responses. Six patients developed proliferative responses to low concentration IL-2 stimulation. All patients demonstrated an increase in median HIV-1-specific responses, as three had detectable virus at baseline (two being viral rebound); this may reflect an autovaccination effect. Proviral DNA changes largely reflected plasma HIV-1 ribonucleic acid (RNA). In conclusion, NNRTI substitution for a PI may favour immune reconstitution with an improvement in HIV-1-specific responses, which may reflect differential effects on antigen processing and presentation, an autovaccination effect or alternatively a potential suppressive effect of the PI.

    Notes: Summary The phenotypes of seed progeny (R2 generation) of Oryza sativa L. cv. Taipei 309, which carried the neomycin phosphotransferase II (npt II) gene, were compared with those of non-transformed, protoplast-derived plants of the same generation and non-transformed, seed-derived plants under field and glasshouse conditions. Under both conditions the transgenic plants were generally smaller, took longer to flower and had reduced fertility. Significant differences were observed between individuals within the group of transgenic plants. The npt II gene was present in most of the transgenic plants, but NPT II activity was only detected in a minority of individuals.
