Pregnancy Complications
Pre-eclampsia
and fetal growth retardation, both caused by blockages of the blood vessels of the placenta, are two of the commonest complications
of pregnancy – there are 50,000 cases of pre-eclampsia in Britain a year. In a trial involving more than 9000 women
in 16 countries, a daily dose of 60mg aspirin reduced the risk of pre-eclampsia by 13 per cent. Earlier research suggested
that the benefits were even greater.
colorectal 50%, lung 33%
The results are even more significant when it is done for those taking aspirin daily for 10 or more years. A large number of people are on daily aspirin either because they are in the high-risk coronary group or
for arthritis. Since cancer results from the slow accumulation of cellular changes
over many years, a drug which slows the accumulation of changes would be more significant in preventing cancer when taken
over a longer time-frame.--jk
Evidence
is mounting that regular aspirin usage may reduce the risk of many of today's commonest cancers. First indications of this
were in colon cancer. In a long term study of 90,000 US nurses between 1976 and 1995 those who took 4-6 tablets of aspirin
per week had a greatly reduced incidence of colorectal cancer compared with nurses who did not take aspirin. The longer the
nurses had been taking aspirin the greater the protection they gained.
More recently, a study involving
14,000 women has shown that those who had reported using aspirin 3 or more times per week for at least 6 months were one third
less likely to develop lung cancer compared with women who had taken no aspirin. The risk reduction was even greater for non-small
cell lung cancer.
Also recently published is
a study of the effect of aspirin usage in pancreatic cancer incidence in 28,000 post-menopausal women. In those individuals
who took aspirin 2-5 times per week, the risk of developing pancreatic cancer was 53% lower than in those women who had never
taken aspirin. The more often the women took aspirin, the lower their risk of cancer.
What dose of aspirin to use,
how frequently to use it and even exactly how it works are still unknown but more work is being done to clarify these issues.
What is clear from the accumulating evidence is that regular use of aspirin really does seem to reduce the risk of a growing
range of the commonest and most serious cancers.
Diabetes
Blindness, coronary artery disease, stroke and kidney failure are all common complications of diabetes resulting
from impaired blood circulation. The benefits of taking one aspirin a day are now so widely accepted that it is considered
unethical to perform placebo controlled trials to prove the case.
Dementia
(including Alzheimer’s disease)
Some forms of dementia affects about one in four people aged 70 years or above. There is some evidence that aspirin
may help prevent both the condition resulting from impaired blood flow and the most serious form of dementia, Alzheimer’s
disease. The latter is believed to be an inflammatory condition similar to arthritis.
Aspirin is a highly effective
anti-inflammatory drug and a preliminary study found a lower than expected incidence in patients with rheumatoid arthritis,
who frequently have to take aspirin over a prolonged period. An important trial in South Wales is following the fortunes of
400 men and studying the factors (including aspirin consumption) that may determine the incidence of dementia. However, volunteers
are still being signed up for the trial and conclusive results will not be ready for some time.
New Study Reveals Aspirin’s benefits for Prostate Cancer Patients
Aspirin may increase prostate cancer survival

ATLANTA – Oct. 4, 2004 – Men with prostate cancer might survive longer by regularly taking aspirin,
a new study suggests.
While there have been other studies showing regular use of aspirin or other non-steroidal
anti-inflammatory drugs (NSAIDs) seems to reduce the risk of developing various cancers, including prostate cancer, this is
one of the first to suggest that such drugs may help men with prostate cancer live longer.
The study led by Dr. K
Khanh H. Nguyen, a radiation oncologist at Fox Chase Cancer Center was presented today at the 46th Annual Meeting of the American
Society for Therapeutic Radiology and Oncology (ASTRO).
"Pretreatment NSAID use was associated with significant delays
in distant metastases, decreased rates of second cancers and improvement in overall survival," lead author Nguyen said in
a news release. "Our data suggest a potential benefit of NSAIDs in managing prostate cancer."
The Fox Chase study
involved 1,206 men who had definitive radiation therapy for localized prostate cancer. The researchers compared long-term
treatment outcomes of 232 patients who had used NSAIDs regularly before treatment with the outcomes of the 974 men with no
history of regular NSAID use. Other characteristics, such as smoking, were balanced between the two groups. The follow-up
period averaged more than four and a half years.
After taking into account other variables such as age, Gleason score
and radiation dose, the use of anti-inflammatory drugs remained a predictor for improved overall survival.
Laboratory
studies have suggested that by inhibiting the COX-1 and COX-2 enzymes, NSAIDs may enhance programmed cell death (apoptosis)
and inhibit the development of blood vessels (angiogenesis) that feed a tumor. The Fox Chase researchers concluded that inhibiting
these COX enzymes holds promise in prostate cancer treatment and warrants further studies.

New Study Quantifies Coronary Benefits of Aspirin
An Update on Aspirin in the Primary Prevention of Cardiovascular Disease
Rachel Eidelman, Patricia Herbert, Steven Weisman, & Charles Hennekens, from Arch Intern Med, vol.
163, Sept. 22, 2003.
A meta-study using 5 published trials from 1988 to present, totaling 55,580 randomized participants.
Results:
Among the 55,580
randomized participans (11,466 women) aspirin was associated with a statistically signficiant 32% reduction in the risk of
a first MI and a significant 15% reduction in the risk of all important vascular events, but hand no significant effects on
non-fatal stroke or vascular death.
LONG TERM ASPIRIN USAGE REDUCES ALZHEIMERS DISEASE
Neurology, 2002;59:880-886
Method: In 1995 to 1996 elderly (age 65+) county residents
were assessed for dementia, with current and former use of NSAID, aspirin, and H2RA as well as three other “control”
medication classes also noted. Three years later, interval medication histories
were obtained and 104 participants with incident AD were identified among the 3,227 living participants.
Results: By contrast, former NSAID users showed substantially
reduced incidence (estimated hazard ration = 42), with a trend towards greatest risk reduction among those with extended exposure. Similar patterns appreared with aspirin but not with any other medicines.
