Curing the common cold?October 25, 2005Folk and herbal remedies are often used in the hope that they will prevent the common cold or reduce the severity and duration of symptoms. Yet, few of these compounds are evaluated scientifically. In this study Predy and colleagues randomized 323 study subjects to receive a proprietary ginseng ( Panax quinquefolius ) preparation or a placebo and followed them for 4 months during the winter (September to April). Using predetermined criteria to determine if subject-reported symptoms were "colds," the authors found that ginseng reduced the frequency of colds. Subjects in the ginseng group reported having 2 or more colds less often than subjects in the placebo group (10% v. 23%). Symptom severity and duration were also lessened. In a related commentary, Ronald Turner of the University of Virginia School of Medicine recently evaluated Echinacea angustifolia as a preventive herbal product for the common cold (and found it did not work). He cautions physicians and the public about the difficulties of doing clinical studies of common viral infections, especially when the specific viruses are not identified.

Study offers insights into failed HIV-1 vaccine trial Following the disbandment of the STEP trial to test the efficacy of the Merck HIV-1 vaccine candidate in 2007, the leading explanation for why the vaccine was ineffective - and may have even increased susceptibility to acquiring the virus - centered on the hypothesis that high levels of baseline Ad5-specific neutralizing antibodies may have increased HIV-1 acquisition among the study subjects who received the vaccine by increasing Ad5-specific CD4+ T-cells that were susceptible to HIV-1 infection. Fruit and vegetable intake in pregnant women reduces risk of upper respiratory tract infection Boston University School of Medicine researchers (BUSM) have observed in a study of pregnant women that consumption of at least seven servings per day of fruits and vegetables moderately reduced the risk of developing an upper respiratory tract infection (URTI). Preventing spread of infectious diseases is everyone's responsibility According to a report published today, we must all share responsibility for preventing the spread of diseases such as swine flu, SARS, avian influenza, diarrhoeal and skin diseases, and even the common cold. Bacteria create aquatic superbugs in waste treatment plants For bacteria in wastewater treatment plants, the stars align perfectly to create a hedonistic mating ground for antibiotic-resistant superbugs eventually discharged into streams and lakes. Findings uncover new details about mysterious mimivirus An international team of researchers has determined key structural features of the largest known virus, findings that could help scientists studying how the simplest life evolved and whether the unusual virus causes any human diseases. Matrix protein key to fighting viruses Researchers from Durham University's Centre for Bioactive Chemistry are developing methods that show how proteins interact with cell membranes when a virus strikes. The structure of a giant virus The mimivirus is the largest virus known to scientists, about half of a micrometre (0.0005 millimeter) in diameter. It is more than 10 times larger than the virus that causes the common cold and - unlike other viruses - is large enough to be seen with a light microscope.
