Web-scale pharmacovigilance: listening to signals from the crowd
” Using data drawn from queries entered into Google, Microsoft and Yahoo search engines, scientists at Microsoft, Stanford and Columbia University have for the first time been able to detect evidence of unreported prescription drug side effects before they were found by the Food and Drug Administration’s warning system. ”
Adverse drug events cause substantial morbidity and mortality and are often discovered after a drug comes to market. We hypothesized that Internet users may provide early clues about adverse drug events via their online information-seeking. We conducted a large-scale study of Web search log data gathered during 2010. We pay particular attention to the specific drug pairing of paroxetine and pravastatin, whose interaction was reported to cause hyperglycemia after the time period of the online logs used in the analysis. We also examine sets of drug pairs known to be associated with hyperglycemia and those not associated with hyperglycemia. We find that anonymized signals on drug interactions can be mined from search logs. Compared to analyses of other sources such as electronic health records (EHR), logs are inexpensive to collect and mine. The results demonstrate that logs of the search activities of populations of computer users can contribute to drug safety surveillance.

Covering DiEthylStilbestrol worldwide drug disaster
Over the past few days, there has been an unprecedented flurry of media attention on DES related health issues. This come after a long-awaited DES study was published on October 06th in the New England Journal of Medicine (MEJM) which carefully documents elevated risk for women exposed to diethylstilbestrol (DES in short) for a host of medical problems including cancer, infertility, ectopic pregnancies, preterm labour, …. As yet, there has been no coverage from the UK press despite a call on UK journalists to make this information available to the public.
DES prescribed to women in the 1940s, 1950s, and 1960s to prevent miscarriages, had serious, untoward effects in daughters of these women, including the development of a rare type of cancer of the uterus. There has been renewed interest in light of a recent report in the New England Journal of Medicine documenting lifelong health complications facing daughters of women given DES.
Reproductive tissues are not the only targets of DES. The immune system is also known to be a target for estrogens. Dr. S. Ansar Ahmed, professor of immunology at Virginia Tech, led a National Institutes of Health study in the 1990s on how exposure to DES in utero affects the immune system later in life using a mouse model.
