Carbohydrate vaccines in cancer: immunogenicity of a fully synthetic globo H hexasaccharide conjugate in man.

The complex carbohydrate molecule globo H hexasaccharide has been synthesized, conjugated to keyhole limpet hemocyanin, and administered with the immunologic adjuvant QS-21 as a vaccine for patients with prostate cancer who have relapsed after primary therapies such as radiation or surgery. Globo H is one of several candidate antigens present on prostate cancer cells that can serve as targets for immune recognition and treatment strategies. The vaccine, given as five subcutaneous vaccinations over 26 weeks, has been shown to be safe and capable of inducing specific high-titer IgM antibodies against globo H. Its immunogenicity was confirmed in prostate cancer patients with a broad range of stages and tumor burdens. Observations of several patients who had evidence of disease relapse restricted to a rising biochemical marker, prostate-specific antigen (PSA), indicated that a treatment effect could occur within 3 months after completion of the vaccine therapy. This effect was manifested as a decline of the slope of the log of PSA concentration vs. time plot after treatment compared with values before treatment. Five patients continue to have stable PSA slope profiles in the absence of any radiographic evidence of disease for more than 2 years. The concept of using PSA slope profiles in assessing early treatment effects in biological therapies such as vaccines awaits further validation in phase II and III trials. The use of a variety of lesser known candidate glycoprotein and carbohydrate antigens in prostate cancer serves as a focus for the development of a multivalent vaccine of the treatment of relapsed prostate cancer in patients with minimal tumor burden.

Neonatal infrared axillary thermometry.

The authors compared axillary skin temperatures (AT) measured with an infrared (IR) thermometer (Lightouch Neonate, Exergen Corp) with rectal temperatures (RT) in 16 newly born term infants under radiant warmers (RW) and in cribs. Twelve stable, growing premature infants in incubators were also studied. This new device may be useful because of safety and rapid results (1 second), but clinical accuracy is unknown. For term infants, mean (SD) RT-AT difference was 0.1 (0.48) degree C under RW and 0.25 (0.17) degree C 2 hours later in cribs. For premature infants in incubators the mean RT-AT difference was 0.09 (0.16) degree C. Axillary temperatures measured by IR thermometer approximate RT for newly born term infants in cribs and stable premature infants in incubators. For newly born term infants under RW, RT-AT differences vary more widely, limiting clinical usefulness in this setting. The device, the unique age of this population, and the RW environment may play a role.
