29 Jan 01 - Medicine - FDA Approves Drug for Deadly Fungus

Staff Reporter

Guardian- Monday 29 January 2001


WASHINGTON (AP) - The government approved a new drug called Cancidas on Monday for immune-weakened patients suffering an often fatal fungal infection.

The intravenous drug is the first in a new family of anti-fungal medicines called echinocandins that work by attacking fungal cell walls.

The Food and Drug Administration approved Cancidas to treat infections known as invasive aspergillosis in seriously ill patients for whom other therapies have failed.

The Aspergillus fungus is very common and doesn't harm most healthy people. But it can kill people with weak immune systems, such as cancer and AIDS patients and organ transplant recipients.

Manufacturer Merck & Co. gave Cancidas, known chemically as caspofungin acetate, to 63 patients. All had failed or couldn't tolerate other treatments, so the FDA didn't demand that Cancidas be compared with an alternate drug or dummy pill.

Half of the 52 patients who received more than seven days of IV Cancidas significantly improved or saw the infection resolve.

The most common side effects were fever, infused vein complications, nausea, flushing and vomiting.

Cancidas is not a first-line treatment for newly diagnosed patients, nor should it be used together with cyclosporin, a common drug among organ recipients, FDA warned.

Merck said Cancidas will be available in 10 days, and cost $288 per daily IV infusion.


29 Jan 01 - Medicine - Cancer risk falls if women extend breast feeding

By David Derbyshire, Medical Correspondent

Telegraph- Monday 29 January 2001


Women who continue to breast feed long after their children have started on solid foods may be protecting themselves against breast cancer, a study suggests.

Researchers have found that mothers who breast feed past a child's second birthday are half as likely to develop the disease as those who stop at 12 months. The study is the latest to show benefits from extended breast feeding.

Dr Tongzhang Zheng, of Yale School of Medicine, New Haven, Connecticut, chose to study China for its long-term traditional breast feeding. "In Chinese society, it is socially acceptable to breast feed for a long time and it is considered good for the child."

He investigated the relationship between breast cancer risk and lactation between 1997 and 1999 in Shandong Province hospitals. He took into account the number breast fed, duration of breast feeding per child, how many years women were breast feeding and the age at which they began.

Dr Zheng found 404 women with breast cancer and compared their lifestyles with a sample of women without the disease. Mothers who breast fed each child for more than two years were half as likely to develop breast cancer compared to women who breast fed for less than 12 months.

Long-term breast feeding also appeared to reduce the risk of breast cancer among post-menopausal women. The age of first breast feeding and the total number of children breast fed did not seem to make any difference.

Dr Zheng said: "This is a crucial time to do a study in China because of the country's one child policy. If we do not take the opportunity to do this study now, the opportunity will be lost."

Studies in Western countries found that breast feeding was not significant in reducing breast cancer risk. Some have suggested that the effect is limited to pre-menopausal women, but that could be explained by few women in the West breast feeding for more than a year.

Dr Zheng said: "We probably will never be able to resolve this issue in cultures where they do not have long-term breast feeding history. Our findings in China are clear. The longer duration of lactation - whether it is based on breast feeding of a first child or breast feeding over a lifetime - leads to a significantly reduced risk of breast cancer."

His research, published in the American Journal of Epidemiology, followed three studies conducted in the early Eighties in Shanghai, Beijing and Tianjin. Then, scientists found a 50 per cent reduction in breast cancer among women who breast fed for more than 109 months in total compared to women who never breast fed.


28 Jan 01 - Medicine - Ulster develops mobile heart test

Vincent Kearney

Sunday Times- Sunday 28 January 2001


Scientists in Northern Ireland are developing a mobile phone that will double up as a heart monitor. The handset, designed by researchers at the University of Ulster, will allow doctors to assess patients' health remotely.

It is expected to reduce hospital waiting lists by allowing some patients to be sent home shortly after surgery.

Patients will attach electrodes to their chest and plug a special device into the phone socket currently used for hands-free sets. The sensors will then monitor their heart rate and body temperature, and store the information in the attachment. A computer will then call the phone at set intervals, transmitting its data to a receiver at the clinic or hospital. If problems are identified, doctors will contact their patients.

The team is also developing a remote diagnostic system. This will allow surgeons to instruct ambulance staff on emergency treatment to heart-attack victims using information transmitted from the sensors.

Northern Ireland has the highest rate of coronary deaths in western Europe. More than 4,000 people died from heart disease there last year, a death rate 20% higher than in the rest of Britain. The republic also has a high incidence of heart disease.

Cardiac surgery in Northern Ireland is carried out at the Royal Victoria hospital in west Belfast, but operations are restricted because there are only 10 intensive care beds for adults and three for children.

Andrew Dougal, chief executive of the Northern Ireland Chest, Heart and Stroke Association, said: "Being able to diagnose the condition of a heart-attack victim remotely would be an asset, because the first few minutes of treatment are absolutely vital. The chances of survival would be increased if a cardiac surgeon were able to supervise the work of paramedics at the scene.

"The ability to monitor a patient's health from a distance would greatly reduce the anxiety for people waiting for surgery, as well as providing peace of mind afterwards. It would also tackle the problem of bed shortages, the main reason why 230 people in Northern Ireland had cardiac surgery postponed last year."

Dougal warned that the waiting lists for heart surgery were set to grow because of delays in replacing the senior cardiac surgeon in the province. Hugh O'Kane, the senior consultant surgeon at the Royal, retired in November, but his replacement is not expected to take up his post for another three months.

Dr Noel Evans,who has been researching telemedicine for 20 years, said the system would have built-in safeguards. The cable carrying data from sensors would also fit land lines, and short-range radio links would boost signals where cellular reception was poor.

"This will be of particular benefit to people who have undergone surgery and are well enough to be released but are kept in hospital because their condition needs monitoring. It will also provide reassurance for people on waiting lists who are considered to be at risk."

Researchers plan to improve the system to enable it to alert doctors to changes in patients' heart rate or temperature.

Royal Victoria hospital's cardiology centre, which helped to develop the world's first cardiac ambulance in 1967, is collaborating on the project and clinical trials are under way. The research is being funded by charities, private donations, Northern Ireland's Engineering and Physical Research Council and Orange, the telecoms company.

The university has been at the forefront of telemedicine research for a number of years. It developed body-surface mapping, which uses electrodes to produce a colour image identifying the cause of chest pain in the early stages of a heart attack. Meridian Technologies, an American company, manufactures the equipment in Belfast and sells it to hospitals around the world.

Professor John Anderson, head of the school of electrical and mechanical engineering at the university, says bodymapping data and other diagnostic information will be relayed by mobile phones. "It is the sensor technology that will make the decisions and that is what we are developing," he said. "The next move will be to integrate all the sensory technology into phones.

"That means the phone could transmit data on potassium and chlorine levels in addition to heart rate, blood pressure and temperature. That will enable doctors to identify problems and begin introducing treatment at a much earlier stage."

The development will be embraced by the medical profession if it reduces waiting lists. Dr Brian Patterson, chairman of the GPs' committee of the British Medical Association in Northern Ireland, said the health service was in crisis.

"Politicians keep telling us that the health service is improving rapidly, but that does not match what I am seeing clinically. We are heading for a nightmare scenario unless something is done quickly," he said.

How mobiles can provide a health check

The handsets, developed by the University of Ulster, come with a special attachment to store the information

1 Patient will have electrodes attached to chest to monitor heart rate, along with heat sensors inside a wound or under the armpit

2 The electrodes would be connected to a mobile phone. This could be worn on a belt, the connections being concealed by clothes

3 A computer in a hospital is programmed to call the phone at regular intevals to receive data

4 If evidence of problems exists, a doctor will be alerted and the patient will be called on the phone asking them to report for treament or take medication


28 Jan 01 - Medicine - Man's germs wiped out mammoths

Robin McKie, science editor

Guardian- Sunday 28 January 2001


Disease can kill off whole species - including ours

They were some of the most remarkable creatures to roam the Earth. For aeons, mammoths, mastodons, giant armadillos, dog-sized rodents, sloths as big as giraffes, and sabre-toothed tigers ruled the plains and forests of North and South America.

Then, 11,000 years ago, they vanished from the face of the Earth, a disappearance that still provokes fierce arguments among scientists.

But now a leading palaeontologist believes he has found the cause of the extinctions: these great animals died because they caught coughs and colds from human beings. And the implications for our planet could be catastrophic. 'Upward of 130 species disappeared in a time period of maybe half a millennium or less,' said Dr Ross MacPhee, of the American Museum of Natural History in New York. 'Disease is the only thing that I know of that could do that.'

The disappearance of the great mammals was originally described by Charles Darwin. 'It is impossible to reflect on the state of the American continent without astonishment,' he noted. 'Formerly, it must have swarmed with great monsters; now we find mere pygmies.'

For the next 100 years, scientists struggled to make sense of the disappearance of the mammoth, mastodon and giant sloth. Then they began to date the bones of these creatures and found they had all been wiped out within a few hundred years of each other. Crucially, it was at this time that humans first travelled to America, from Asia across a land bridge that joined Siberia and Alaska, leaving signs of their progress in the form of carved stone arrowheads and spearpoints. These early Americans were clearly great hunters, and were quickly fingered as the eradicators of America's mammoths and mastodons.

'Large animals disappeared not because they lost their food supply but because they became one,' says Dr Paul Martin of Arizona University, protagonist of the 'overkill hypothesis'.

But the theory suffers from a major drawback, scientists have realised: there is little evidence to support it. Despite a plethora of fossil remains, only six mammoth bones have been found with spearpoints in them. As for the other 130 species wiped out, not one has been found near an arrow or with a sign of having been butchered.

'People were hunting but not on a scale that could have made any difference to the survival of the species,' says MacPhee. 'You'd have to be killing things all the time and you'd have to be doing it for some purpose. It's unimaginable that the people concerned would be interested merely in killing, especially large, dangerous animals like mammoths.'

Instead MacPhee believes America's great creatures were victims, not of human aggression, but of diseases introduced by us, or possibly by animals such as dogs or rats travelling with us. 'You can imagine a situation, especially for herding animals, where the pathogen could be passed through a population in days,' he argues. 'They would be falling all over the place, without any clear threat at hand.'

MacPhee points to recent epidemics introduced by humans that have wiped out species of toads and frogs in North America, and populations of birds such as the Hawaiian honeycreeper. Similarly, African wild dogs in the Serengeti have been killed off by canine distemper transferred from domestic dogs, while rinderpest - introduced into Africa 100 years ago - eradicated millions of wildebeest, hartebeest and others.

Such outbreaks are trivial compared with those that could have been triggered by humans leaving Africa and Asia and entering America for the first time. 'All kinds of organisms could have been brought to places where humans had never been previously resident,' says MacPhee, whose ideas will be outlined in next month's Scientific American. In a bid to prove this idea, MacPhee is probing tissue of mammoths found in permafrost. He aims to extract the DNA of bacteria, viruses or protozoa, and provide crucial evidence for his theory.

If he succeeds, he believes he will have demonstrated that our planet and all its species, including humans, will always be highly vulnerable to disease. Just as we infected and killed off the mammoth, so the animal world has given us ailments ranging from flu, which originated in poultry, to Aids, which we got from apes. One disease could mutate with effects as final as the one that killed off the giant sloth. Consider the flu epidemic of 1918, he says. 'This was the worst killer plague in recent times - it killed between 20 and 40 million people in a year and a half. Yet this novel flu evidently gained its lethality through a couple of substitutions in a couple of its genes.

'These things are going on in the disease pool we all share in all the time. I suggest we should be very, very frightened by these facts.'


28 Jan 01 - Medicine - Couch-potato children fall victim to diabetes epidemic

Mark Gould

Guardian- Sunday 28 January 2001


Anita Ellis became part of Britain's most worrying medical puzzle one night in May last year, when she woke with agonising stomach pains. Her doctor gave her a painkiller. Over the next few days she had a series of tests and was diagnosed as having adult-onset diabetes. The doctors were surprised because Anita was only 15.

But she is not alone. The Observer has learnt that doctors in other parts of the country have seen nine-year-olds with the same type of diabetes, which is normally seen in people 30 years older.

With more than a million under-16s in the UK classed as overweight or obese - double the number in the mid-Eighties - doctors are becoming convinced a junk food and couch-potato lifestyle is speeding their bodies into a disease of middle age.

In obese diabetics, the cells producing insulin to control blood sugar wear-out, fighting a losing battle to maintain the body's equilibrium. Undiagnosed diabetes can lead to infertility and eye damage, or even fatal kidney or heart disease.

Anita has come to accept that she has a condition that is a symptom of cellular middle-aged burn-out. 'At first I didn't want to tell my friends because they would think I was strange. They were very understanding when it was explained what they would have to do if I had a funny turn. And they understood that I would have to do a blood sugar test four times a day, take tablets and change what I eat,' said Anita, who lives in Romsey, Hampshire.

Since her diagnosis Anita, now 16, has lost over a stone in weight and is taking tablets and regular exercise, which it is hoped will stave off early health problems. 'The doctors were really surprised and at first I was really scared when it was diagnosed.

'I used to love my chips and crisps, but now I only have chips once a week and have cut out crisps and chocolate altogether and take fruit to school. And I do feel a lot healthier and happier since I was diagnosed.'

Doctors Sarah Ehtisham, Nick Shaw and Tim Barrett uncovered the first-ever British cases of type 2 diabetes in eight obese children in Leicester and the West Midlands. The youngest was nine when diagnosed. She had to have eye surgery after developing a cataract - a classic complication of diabetes.

'These are the first cases of type 2 diabetes in children in the UK, although this has become a well-recognised problem in other parts of the world, notably the US,' said Barrett. 'The onset of this form of diabetes at a young age means there will be more time for complications to develop over the lifetime of the individual.'

The World Health Organisation and the charity Diabetes UK estimate that there are a million 'hidden' diabetics in the UK. Doctors fear many are children who will not be diagnosed until serious damage is done. They want to raise awareness among doctors because medical training doesn't recognise type 2 diabetes in children. In Japan, type 2 is now the most common form in children. In the US, where nearly half of child diabetics are type 2, there is routine screening.


27 Jan 01 - Medicine - Dentist cures severe case of tusk ache

From Allan Hall In Berlin

Times- Saturday 27 January 2001


An English dentist was called upon to operate yesterday on an Indian elephant that had lost part of its right tusk at a German zoo.

Dr Peter Kertesz was told that the eight-year-old patient, Chamundi, had been in agony for several months after fighting with other elephants at the zoo in Münster, northwest Germany. His remaining 20in stump was in danger of infection.

Dr Kertesz, who spends most of his time at a London dental surgery, was asked to help because he is the founder of an organisation called Zoodent and has operated on many animals.

"An elephant with toothache is not a very happy creature," a Münster Zoo spokesman said. "But he is back on his feet after the operation and feeling a little groggy but otherwise fine."

Dr Kertesz and his team of five, including Dr John Lewis, an anaesthetist, made the elephant unconscious with a drug called etorphine, which has 10,000 times the tranquillising power of morphine.

Once on his side, Chamundi was fed gas as Dr Kertesz set to work with an industrial drill in a four-hour operation.

"We tried rotating the tusk and pulling it, but it wasn´t coming out," he said. "In the end we drilled down through the tusk - it is just like a tooth, only a long curved cylinder - and began hollowing it out at its base until I could cut it in four sections and extract each one."

Zoo officials said that Chamundi might later be fitted with a false tusk.


27 Jan 01 - Medicine - Diabetics 'freed from tyranny of daily jabs'

By Lorna Duckworth, Social Affairs Correspondent

Independent- Saturday 27 January 2001


A potential "cure" for thousands of people suffering from the most serious form of diabetes is to be tested in Britain. The pioneering technique, which ends the daily routine of life-saving insulin injections, was developed by a British-born surgeon in Canada.

Cell clusters that produce insulin are transplanted into the livers of diabetics so they can create the hormone that regulates blood glucose levels themselves. Thirteen of the 15 patients who have had the ground-breaking cell transplants in Canada have been "effectively cured" and no longer require daily injections.

The charity Diabetes UK is funding seven centres at British hospitals where the technique developed by James Shapiro will be tested. Britain has about 1.4 million known sufferers of diabetes, a condition in which the body cannot convert blood glucose into energy because insulin is not produced or does not work properly.

Half a million diabetics rely on daily injections of insulin to maintain their glucose levels, and 50,000 of these have the most serious Type 1 form of the disease.

In a £300,000 pilot this summer, 10 British patients will receive cell transplants and, if successful, the project could be expanded to treat up to 400sufferers each year. These patients would have to spend the rest of their lives on a cocktail of drugs to prevent the bodyrejecting the pancreatic cell clusters.

Because of the potential and as yet unknown dangers of long-term immuno-suppression drugs, the treatment is considered suitable only for people with Type 1 diabetes.

At the launch of the project yesterday, Moira Murphy, director of research at Diabetes UK, said: "It is early days yet, but this may well lead to a cure for diabetes. If this research proves successful, it could revolutionise the lives of people who currently need to take daily insulin injections just to stay alive."

Scientists warn that several years will be needed to see whether the transplants have worked and the technique is a definite cure. But one of the Canadian patients, who has had more than 40,000 insulininjections since he was diagnosed 40 years ago, said his life had been transformed.

Bob Tesky, 54, of Alberta, said: "In the past year I have seen a miracle happen in my life. Even in my wildest dreams, I never expected there would be a day when I would no longer need to go through the routine of insulin, blood tests, all of the anxiety that accompanies this disease. I always expected that sooner or later things would get worse, I never expected things could be so dramatically better.

"I have not taken an insulin injection since last August. Amazingly, all of the key tests show I am functioning as a normal non-diabetic."

The British centres are at King's College Hospital and the Royal Free Hospital in London, Oxford Transplant Centre and Nuffield Department of Surgery, Southmead Hospital in Bristol, Worcestershire's Acute Hospital NHS Trust, Addenbrooke's Hospital, Cambridge and the University Hospitals of Leicester.


27 Jan 01 - Medicine - Diabetes 'cure' to undergo test

Ananova

PA News- Saturday 27 January 2001


A potential cure for diabetes is to be tested in the UK.

The pioneering technique involves transplanting cells into the livers of diabetes victims and puts an end to the need for daily insulin injections.

The transplantation technique has been developed in Canada by British-born surgeon James Shapiro and has so far led to 13 patients being effectively "cured".

About 1.4 million people in the UK are diagnosed with diabetes and an estimated million more have the condition but are not aware of it.

Diabetes stops the body converting the glucose in its blood into energy because the hormone insulin is either not produced or does not work properly.

Half a million diabetes sufferers have to give themselves daily injections of insulin to maintain their glucose levels, and 50,000 of these have the most serious Type 1 form of the disease.

In Type 1 diabetes, the islet cells in the pancreas which produce insulin are for some reason destroyed by the body's own immune system.

Mr Shapiro has developed a technique where islet cells are taken from a donor and injected into the diabetes sufferer's liver.

The process can be completed in half a day and is done under local anaesthetic. After two injections, the cells kick-start the body's insulin production, although patients have to take anti-rejection drugs for the rest of their lives.

So far 13 of the 15 patients who have had islet cell transplantation in Canada no longer have any need for daily insulin injections but scientists warn it will take several years to see whether the transplants have worked and the technique is a "cure".


26 Jan 01 - Medicine - Alternative to stem cell therapy developed

By Nigel Hawkes

Times- Friday 26 January 2001


British scientists have developed a way of using immortal human cells to repair bone and renew the brain. The method offers an alternative to stem cell therapy which they believe will work better and will raise no ethical issues.

Normal cells divide only a limited number of times before they die, but the new technology, developed by Dr Bradley Stringer of Sheffield University and Dr George Foster of Cardiff University, cancels out this process, enabling an infinite number of cells to be generated from the original source.

Clinical trials of the new bone-repair material could begin within 12 to 18 months at Sheffield University, with a possible treatment for Parkinson's disease to follow a year or two later.

The cells are not stem cells - research into which was approved by the House of Lords after a debate on Monday - but specialised cells that can be multiplied indefinitely in culture dishes.


26 Jan 01 - Medicine - Thalidomide is used in cancer treatment

By Jeremy Laurance, Health Editor

Independent- Friday 26 January 2001


Thalidomide, the most feared drug of the last century, is to be tested on 30 lung cancer 30 patients in London and Leeds. The once-notorious drug was banned in 1962 after pregnant women who took it to quell morning sickness gave birth to an estimated 12,000 deformed babies worldwide. But thalidomide is making a gradual comeback.

Scientists have discovered properties unrecognised 40 years ago, and are harnessing them to treat a range of diseases. Its dangerous teratogenic effects, causing birth defects, apply only if it is taken by women who are pregnant.

Thalidomide has been shown to be a highly effective treatment for a form of bone cancer called multiple myeloma and has been used to treat HIV, rheumatoid arthritis and Bechet's syndrome, which causes ulceration of the eyes, mouth and nose. It is also licensed in the US for the treatment of severe ulceration and leprosy. In Britain, it has been used to treat brain cancer, kidney cancer and Kaposi's sarcoma, a cancer involving the blood vessels of the skin common in patients with HIV.

The Cancer Research Campaign is backing the latest trial of the drug in patients with small-cell lung cancer, the most deadly form of the disease, that kills around 9,000 people a year. Professor Gordon McVie, the director-general, said: "This is preliminary work and highly speculative. It is early days but we are excited by the potential."

The researchers, led by Dr Siow Ming Lee from University College, London, hope to harness the same property that caused birth defects, by limiting blood flow to developing limbs, to attack the cancer by starving the tumour of the oxygen it needs to grow. Thalidomide is thought to inhibit the growth of blood vessels that feed tumours and maystabilise the blood flow.


26 Jan 01 - Medicine - Doctors attack research on MMR

by Zoe Morris, Health Reporter

Evening Standard - Friday 26 January 2001


The controversy over the combined measles, mumps and rubella jab continued today, as two London doctors attacked a third's research which linked the vaccine with autism and bowel disease.

The latest twist in the saga over the triple vaccine, which has left parents confused over what is the safest way to protect their children, adds weight to the Government line that MMR is safe.

Dr David Elliman, of St George's, and Dr Helen Bedford, of Great Ormond Street Hospital, today publish an editorial in the British Medical Journal in which Dr Andrew Wakefield is accused of publishing "incomplete" research and not taking an "impartial" approach to the debate.

Dr Wakefield, a gastroenterologist at the Royal Free Hospital, claims to have identified a distinct syndrome among children affected by MMR - featuring autism and bowel disease. He also raised doubts about trials of the vaccine in the Seventies, suggesting they were not long enough and that some of the children involved experienced side-effects.

However, the BMJ article states: "We have reviewed the latest developments in this saga and are convinced that such confusion and anxiety about MMR vaccine are unfounded."

It adds: "However weak the scientific evidence

which triggers vaccine safety scares, they provoke anxiety among parents and health professionals which can lead to a decline in vaccine uptake."

In some parts of London the uptake of MMR has fallen to less than 75 per cent - sparking fears of reemergence of measles, which claimed the lives of two children in Dublin last summer.

The doctors say Dr Wakefield's latest research added "nothing new" and other studies of the vaccine over the past 30 years have proved it to be safe.

Dr Bedford told the Standard parents need to be reassured about the vaccine. "I keep imagining I'm a parent waking up on the morning when my child is supposed to have their MMR and there are all these stories in the papers and safety fears," she said. "It is not appropriate that people are making decisions based on what they read in the newspaper."

Dr Wakefield was not available for comment. The Government has launched a £3million campaign aimed at convincing parents the triple vaccine is safe, but 2,000 families are preparing legal cases, claiming children developed autism after the jab.

Meanwhile, Sarah Dean, director of the Direct Health 2000 clinic which has been giving children separate doses of the vaccines, has renewed calls for the Government to lift restrictions on importing the unlicensed vaccines. Currently, the Medicines Control Agency has to be notified about any imports and shipments are limited to 25 doses at a time.


23 Jan 01 - Medicine - Downs syndrome may hold cure to lung cancer cure

Ananova

PA News- Tuesday 23 January 2001


Scientists think victims of Down's syndrome may hold a vital new weapon against lung cancer in their genes .

Researchers found that people with the genetic disorder, which affects about one in 600 newborn babies, have an extra copy of a gene that appears to protect against lung cancer .

In most people genes come in pairs, but Down's sufferers have three copies of the newly identified gene, called USP25. The same gene is often missing from the tumour cells of people with lung cancer.

Scientists believe the discovery may help them develop new drugs or gene therapies that can fight or prevent the disease, which affects about 40,000 people a year in the UK.

A team from the Cancer Research Campaign charity made the connection after noticing that people with Down's syndrome were much less likely than the rest of the population to develop common cancers, including lung cancer.

Down's sufferers are less than half as likely than the rest of the population to develop many solid tissue cancers. But they are 10 to 20 times more likely to develop childhood leukaemia.

Dr Dean Nizetic, from the University of London's Centre for Applied Molecular Biology, who led the research, said: "This gene could be an important part of the body's complex protective mechanism that stops people from developing lung cancer.

"When cells lose their protective genes, that's when they're likely to turn cancerous.

"People with Down's syndrome are resistant to many forms of cancer. Thanks to this, we may now find new ways of preventing these types of the disease, including lung cancer, potentially saving many lives. Progress will also be a tribute to the scientists who decoded the genetic information responsible for Down's syndrome."

The scientists now hope to find out for certain whether USP25 protects against lung cancer and exactly how it works.


23 Jan 01 - Medicine - Peers back cloned stem cell research

By Melissa Kite And Roland Watson

Times- Tuesday 23 January 2001


Controversial new research on human embryos was given the go-ahead last night after peers backed government legislation to allow testing on cloned stem cells.

Scientists and government supporters defeated an attempt by religious leaders and pro-life campaigners to delay the research for several years by 212 votes to 92.

An amendment paving the way for a select committee inquiry to monitor the initial stages of the new research was agreed by peers unopposed. The parliamentary order, which extends scientific research using cloned embryos that can at the moment be used only for fertility treatment, comes into effect at the end of the month.

The Government's opponents, led by Lord Alton of Liverpool, had argued that a select committee should study the issues in greater detail before the order was given parliamentary approval. That would have wrecked the Government's proposed change, forcing ministers to return to the issue afresh in the next Parliament.

The decision came at the end of an impassioned debate in which opponents of so-called "therapeutic cloning" of human embryos argued the move ignored the sanctity of life. Lord Alton said it would allow human embryos to be treated as "just another accessory to be created, bartered, frozen or destroyed".

Other critics included the Archbishop of Canterbury, the Roman Catholic archbishops of Glasgow and Westminster, the Chief Rabbi and the President of the Muslim College.

But supporters, including the eminent neurosurgeon Lord Walton of Detchant, said that there were people suffering from a range of illnesses who did not have time to wait.

Lord Hunt, the Health Minister, said that embryo research could prove critical those suffering from Parkinson's disease, cancers, strokes, heart disease and other serious conditions. The science was clear that stem cell research had the potential to provide the answers to many debilitating illnesses.

He said: "The human embryo has a special status and we owe a measure of respect to the embryo. We also owe a measure of respect to the millions of people living with these devastating illnesses and the millions who have yet to show signs of them."


23 Jan 01 - Medicine - Down's gene may help cancer fight

By Celia Hall, Medical Editor

Telegraph- Tuesday 23 January 2001


People with Down's syndrome hold the key to finding a gene that may help to protect against lung cancer, scientists believe.

Research has shown sufferers with the syndrome have three copies of the gene, which is one more than the rest of the population. The gene, USP25, is often missing from cancer cells of people who develop lung cancer. The researchers believe that the loss of the gene could play an important part in developing the disease.

A team run by Dr Dean Nizetic at the School of Pharmacy, London University, has been working with Dr Denise Sheer of the Imperial Cancer Research Fund. Dr Nizetic said: "This gene may be an important part of the body's protective mechanism that stops people from developing lung cancer. When cells lose their protective genes, that's when they are likely to turn cancerous. People with Down's syndrome are resistant to many cancers. Thanks to this we may find ways of preventing these types of the disease."

The gene is similar to others which are known to have protective effects against cancer. Prof Gordon McVie, director-general of the Cancer Research Campaign, said: "The work is vital because if we know how people with Down's syndrome are better protected from cancer then perhaps we can protect the rest of us as well."

Carol Boys, of the Down's Syndrome Association, welcomed any further research especially if it helped to understand why people with the syndrome were more likely to have other health problems.


22 Jan 01 - Medicine - Campaign to promote MMR vaccine

Staff reporter

Times- Monday 22 January 2001


A £3 million publicity campaign to reassure parents about the safety of the controversial MMR vaccine was announced by the Government today.

A massive newspaper and television advertising offensive will be launched in the next two weeks, aimed at encouraging parents to get their children vaccinated.

It comes in response to the latest claims that the combined measles, mumps and rubella jab was not adequately tested before being launched in the UK and may be linked to autism and bowel disease.

Immunisation levels have fallen dramatically since fears over the jab were first raised three years ago.

Yesterday Dr Andrew Wakefield, the expert who originally raised concerns over the jab, repeated claims that trials of the vaccine were not adequate and that there could be a link to autism.

Today the chief medical officers for England, Wales, Scotland and Northern Ireland met to discuss how to allay growing concerns.

Professor Liam Donaldson, the chief medical officer for England, said: "Whenever there is a health scare parents are left confused.

"They should be left in no doubt after today's summit that the advice from doctors, nurses and every major health organisation is that they should have their child vaccinated with MMR."

The newspaper campaign will begin on Thursday and a month-long television advertising push aimed at mothers of young children will be launched in February.

Information packs will also be sent to 30,000 GPs, health visitors and nurses to persuade them that the jab is safe for children.


22 Jan 01 - Medicine - Experts try to ease fears over MMR jab

Telegraph- Monday 22 January 2001


Medical experts will hold a summit meeting today to draw up a strategy aimed at reassuring the public about the safety of the measles, mumps and rubella (MMR) vaccine.

The move follows yesterday's publication of research that raises doubts about the vaccine's safety. A Department of Health spokesman said: "The purpose of the summit is to reassure the public about the safety of the vaccine and explain why it is much better than the alternative of having single vaccines. We all agree about this. The only person who doesn't is this man Dr Andrew Wakefield."

Dr Wakefield, a consultant gastroenterologist at the Royal Free Hospital in London, criticised trials of the jab in an article in the medical journal Adverse Drug Reactions. He claims the trials were too small and did not follow children up for a long enough period to gauge problems.

Dr Wakefield's report said there was evidence more than 20 years ago that combining three live viruses in one jab could be dangerous. His study concluded that there were indications that the triple jab was linked to autism and inflammatory bowel disease.

But the Department of Health and the Medicines Control Agency accused researchers of scaremongering and "totally rejected" that MMR vaccines were licensed prematurely. The British Medical Association insisted that the vaccine was safe, although Dr Dr Wakefield's research links it to nearly 170 cases of autism and bowel disease.

In parts of the country the vaccination rates have dropped from 92 per cent to 75 per cent, a level that experts say could lead to a fatal measles epidemic. About 500 parents are taking action against the Government, claiming their children developed Crohn's disease after receiving the jab.


22 Jan 01 - Medicine - Health chiefs act to shore up confidence in MMR vaccine

By Jeremy Laurance, Health Editor

Independent- Monday 22 January 2001


The government wheeled out the heavy guns of the medical establishment yesterday to counter the growing crisis of confidence in the MMR vaccination programme, which threatens a measles epidemic.

Liam Donaldson, the chief medical officer, drew on the support of several medical organisations to declare MMR safe and effective and to reject calls for it to be separated into three single vaccines.

Reflecting the Government's frustration at the growing controversy over the MMR vaccine's supposed risks, Professor Donaldson announced a £3m publicity campaign, to be launched on Thursday, to bolster public confidence.

Many parents have been alarmed at reports of its alleged links with bowel disease and autism, and private clinics offering the single vaccines have been overwhelmed. National vaccination rates have fallen from 93 per cent to 88 per cent - and in some areas as low as 74 per cent - raising the risk of an outbreak of the diseases.

More than 1.5 million leaflets and 40,000 posters will be distributed, backed by a four-week television advertising campaign in February. A video will be provided for parents at GPs' surgeries and information packs will be sent to health workers.

At a conference on the crisis called by the Health Department yesterday, medical organisations including the Royal Colleges of Paediatrics, GPs and Nurses threw their support for the campaign behind the chief medical officer.

Professor Donaldson said: "Every single one agrees the vaccine is the safest and best way to protect children against measles, mumps and rubella. MMR is used successfully in over 30 countries. On each occasion these health scares are raised, MMR has been given a clean bill of health."

The latest flurry of alarm was triggered by new claims by Dr Andrew Wakefield, of the Royal Free Hospital, London, that it was not properly tested before its introduction in Britain more than 20 years ago.

Dr Wakefield, a specialist in gastro-enterology, triggered the original scare about the vaccine with research papers in 1995 and 1998 suggesting it could be linked with bowel disease and autism. Although he has become more of a lone voice, his warnings have chimed with some parents of autistic children convinced the vaccine caused the mental and physical deterioration.

That concern caused vaccination rates to fall from their peak but nine out of 10 parents still have their children vaccinated with MMR and there were signs the rate was rising again before the latest scare.

Professor Donaldson, with representatives from the Public Health Laboratory Service, the Medicines Control Agency and the British Medical Association, said there was no new evidence in Dr Wakefield's latest report, published in the Journal of Adverse Drug Reactions, to change the view that the vaccine was safe.

Asked why he would not let parents choose single vaccines, he said it would mean abandoning a very effective, safe vaccine that had virtually eliminated the diseases for a strategy which, because of the spacing of separate vaccines, may allow outbreaks of measles, mumps or rubella. Japan, the only country to recommend single vaccines, has had repeated outbreaks of measles with 79 deaths since 1992, compared with none in the UK.

"The evidence is if you introduce single vaccines you place children at risk and I don't want to be responsible as chief medical officer for the deaths of children," Professor Donaldson said.


22 Jan 01 - Medicine - New claims of vaccine danger rebutted

Sarah Boseley, health editor

Guardian- Monday 22 January 2001


New salvoes were fired yesterday in the war between a scientist who believes there is a link between the MMR vaccination and autism and the medical establishment, which has consistently rebutted the hypothesis.

Andrew Wakefield, a consultant gastroenterologist at the Royal Free hospital in London, is now alleging that the combined measles, mumps and rubella vaccination was not tested thoroughly enough for safety before it was introduced in Britain in 1988. In a paper shortly to be published in the medical journal Adverse Drug Reactions, he claims that children given the combined jab were not followed up for long enough to be sure that there were no side-effects.

The renewed battle over the MMR will dismay public health officials, who have warned that there is the danger of a potentially fatal measles outbreak if parents do not take their children for vaccination. Only 88% of children are now being vaccinated because of public uncertainty. In Ireland and the Netherlands, low vaccination coverage last year led to deaths from measles. The World Health Organisation says 95% coverage is advisable to prevent an outbreak.

Yesterday the Department of Health produced a long and detailed rebuttal of Mr Wakefield's latest allegations, based on reviews of his work carried out by independent scientists on the joint committee on vaccination and immunisation and the committee on the safety of medicines.

The paper by Mr Wakefield claims that children given the MMR jab in the pre-licensing trials were not followed up for longer than 28 days and therefore long-term side effects of the vaccinations would not have been picked up.

The Department of Health said yesterday that this was "factually incorrect". Most of the trials followed children for four to six weeks, one particular trial monitored them for six to nine weeks and a minority of children in the trials were followed up for a year. The department accused Mr Wakefield of biased reporting. "Studies that fail to support the author's views are not mentioned," it said.

Mr Wakefield's thesis, which caused a furore when published in the Lancet in 1998, is that the MMR jab can trigger Crohn's disease, a bowel disease, in certain susceptible children, which in turn can lead to autism. He claims in the new paper that some small trials in the US showed that significant numbers of chil dren developed stomach bugs, but that in spite of this, the follow-up period was reduced to 21 days from 28 days.

His original work was on just 12 children whose parents said they showed no signs of autism until after their MMR jab. Mr Wakefield's opponents point out that the vaccination takes place at around 18 months, the same time that autism is usually noticed. A study of all the autistic children in part of north London was commis sioned by the Department of Health, which concluded that there was the same rate of autism in children who had been vaccinated with the MMR and those who had not.

Mr Wakefield and colleagues claimed to have found signs of the measles virus in the gut of autistic children. But nobody has been able to replicate this finding. A panel of top scientists, convened by the medical research council at the request of the Department of Health, reviewed Mr Wakefield's data and found no evidence to substantiate his claim of the link between MMR and either bowel disease or autism.

But many parents of autistic children, searching to understand and explain what has happened to them, are convinced the MMR vaccination must be to blame. Mr Wakefield said yesterday that he now has 170 children on his books, instead of the original 12, and that in most cases the parents could show the autism appeared after the MMR.

Professor Brian Duerden, medical director of the public health laboratory service, said yesterday that he could find "no hard scientific basis at all" for Mr Wakefield's claims. "He is a fervent believer in his views on this," said Prof Duerden. "One person's idiosyncrasy and interpretation puts the vaccination programme and the need to protect children at risk."


22 Jan 01 - Medicine - £3m campaign against the MMR doubters

By Nigel Hawkes, Health Editor

Times- Monday 22 January 2001


The Government is beginning a £3 million publicity campaign to reassure parents about the safety of the MMR vaccine.

Desperate to reverse the decline in the take-up of the vaccine after fears of a link to autism were raised, the Department of Health yesterday organised a "summit" at which leading organisations declared their support for the vaccine, and agreed a joint statement.

The statement rejects claims by Dr Andrew Wakefield, of the Royal Free Hospital, North London, that MMR was introduced before its safety was assured.

Dr Wakefield's reading of the scientific literature is "highly selective" and does not present an accurate picture, the department said. His suggestion that the three vaccines - for measles, mumps, and rubella - should be given separately rather than together raises "real concern" because it would expose children unnecessarily to these potentially serious diseases.

The fear is that if the MMR vaccination rate falls, children will again catch measles, and some will die. In some parts of the country only 75 per cent of children are immunised, far below the World Health Organisation's recommendations that at least 90 per cent must be vaccinated in order to protect the whole population.

Professor Liam Donaldson, the Chief Medical Officer, said after the meeting that the publicity campaign would begin on Thursday with newspaper advertising aimed at the public and professionals.

A month-long television advertising push aimed at mothers of young children will go ahead next month, and information packs will be sent to 30,000 GPs, health visitors and nurses, to persuade them that the jab is safe for children.Professor Donaldson denied that the Government was losing the PR battle over MMR. There was, he said, "a very solid base of parents" - overall, nearly nine out of ten - who had confidence in the vaccine.

"There is a lot of certainty about the safety of the vaccine" he said. "It has been around for decades, millions of children have been vaccinated. It is wrong to focus on a small number of people's claims, against the views of a large number of people who have failed to replicate the results and who are prepared to back MMR.

"We have had discussions today with all of the major health organisations in this country about the MMR vaccination programme.

"Every single one of them agrees that the MMR vaccine is the safest and best way to protect children against measles, mumps and rubella.

"Whenever there is a health scare, parents are left confused. They should be left in no doubt after today's summit that the advice from doctors, nurses and every major health organisation is that they should have their child vaccinated with MMR."

The MMR vaccine is used in the US, Canada, and more than 30 European countries. Dr Liz Miller of the Public Health Laboratory Service told the summit that since 1990, just over a year after introduction of MMR in Britain, there have been no measles deaths, and no cases of meningitis caused by mumps.

A condition related to measles, called SSPE (sub-acute sclerosing pan-encephalitis), whose symptoms are similar to those of CJD, had also disappeared.

By contrast in Japan, where the single measles and rubella vaccines are used, there are still many cases of measles and between 1992 and 1997, 79 children died from the disease.
