Council leader backs campaign to help sick baby

By RACHEL HAWTHORN
THE leader of Portsmouth City Council today called on city residents to join the bone marrow donor register.
Councillor Gerald Vernon- Jackson is the latest person to pledge his support for our campaign to find baby Jasmine Andrew a bone marrow match.

As soon as he heard about the three-month-old’s plight he said he would join the register himself and actively try to recruit people as well.

Cllr Vernon-Jackson said: ‘It seems the least I can do.

‘I’ve carried an organ donor card round for years. What I don’t need, they can have. This is the same. ‘ He added: ‘I will be encouraging everyone I talk to join the register now.

‘The more people we can get to sign up to donate, the better.

‘This is something I really hope lots of people will do.’

The News launched a campaign last week to help tiny tot Jasmine, who has a rare and potentially life-threatening immune system deficiency called Severe Combined Immunodeficiency (SCID). She is constantly vulnerable to infections and viruses and the only cure for her condition is a bone marrow transplant.

Her family made a desperate plea for readers of the News to join the register and see if they are a potential match.

Cllr Vernon-Jackson is now joining the likes of Linvoy Primus and pop duo Same Difference, in pledging his support. He is also helping us to find a venue for a special session in Portsmouth for readers to attend and become donors.

‘I will do whatever I can to help,’ said Cllr Vernon-Jackson.

Jasmine is still at Great Ormond Street Hospital in London being treated by specialists.

She is still trying to recover from a bout of gastroenteritis.

Meanwhile, The News is working with Anthony Nolan – a charity which specialises in finding bone marrow donor matches, to organise sessions across the area.

During the sessions people will be asked to give saliva samples. Dates and venues of sessions will be announced soon.

Linvoy steps in to help in Jasmine’s bone marrow plea

By Unknown
FOOTBALL legend Linvoy Primus is proving he’s a hero off the pitch as well as on it.
The former Pompey favourite is set to join the bone marrow donor register in a bid to help baby Jasmine Andrew.

The three-month-old has a potentially life-threatening immune system deficiency and the only cure is a bone marrow transplant.

As soon as Linvoy heard about the tot’s plight he jumped at the chance to help her and immediately pledged his support for our campaign to find her a bone marrow match.

And now the football star is urging readers of The News to do the same.

He said: ‘I’m more than happy to join the register.

‘If you’ve got an opportunity to help someone, you’ve got to take that. You could literally be a life saver here.

‘I’d definitely encourage News readers to join the register too.’

The News launched a campaign earlier this week to help find Jasmine a bone marrow match.

The tot was born with Severe Combined Immunodeficiency (SCID) and is constantly at risk of infections.

Anthony Nolan – a charity which specialises in finding matches – is backing our campaign to help her.

Together we are set to organise sessions in the area for people to attend and join the register. Linvoy will be joining us at one.

During the events, Anthony Nolan representatives will be on hand to take saliva samples from those willing to join the register.

That sample will then be sent to a laboratory in London where the tissue type will be noted and the person added to the donor register.

If you are found to be a match for Jasmine, or for any other patient in need of a transplant, Anthony Nolan will then contact you.

Linvoy said: ‘I think when you realise how easy and simple it is to do and how effective and life changing it can be, you just can’t say no.’

Details of the bone marrow donor sessions we are organising will be announced soon.

In the meantime, Anthony Nolan are inviting people to sign up online or by calling the charity.

MSD’s Vaccine, ROTATEQ®, Reduced Severe Rotavirus Gastroenteritis in Infants in Asia and Africa

MSD’s Vaccine, ROTATEQ®, Reduced Severe Rotavirus Gastroenteritis in Infants in Asia and Africa

2010-08-06 01:23:02 –

In a study published today in The Lancet, ROTATEQ® (rotavirus vaccine, live, oral, pentavalent), MSD’s rotavirus vaccine, reduced the number of cases of severe rotavirus gastroenteritis by nearly half (48 percent) in infants evaluated in developing countries in Asia (Bangladesh and Vietnam) and by 39 percent in infants evaluated in developing countries in Africa (Ghana, Kenya, and Mali) through nearly two years of follow-up. This is the first study demonstrating efficacy for any rotavirus vaccine in developing countries in Asia and the first study to show efficacy for ROTATEQ in developing countries of Asia and Africa.

“We are encouraged by the data,” said study investigator Dr. Khalequz Zaman, International Centre for Diarrhoeal Disease Research, Dhaka, Bangladesh. “In this study, ROTATEQ prevented severe rotavirus gastroenteritis in infants in regions in Africa and Asia where the disease burden is quite high and rotavirus vaccines are needed the most.”

ROTATEQ is an oral pentavalent vaccine indicated for the prevention of rotavirus gastroenteritis in infants and children caused by the serotypes G1, G2, G3, G4, and G-serotypes that contain P1A[8] (e.g., G9). ROTATEQ may be administered as early as 6 weeks of age. The first dose should be administered at 6 to 12 weeks of age, with the subsequent doses administered at a minimum interval of four weeks between each dose.

ROTATEQ should not be administered to infants with a demonstrated history of hypersensitivity to any component of the vaccine. Infants with Severe Combined Immunodeficiency Disease (SCID) should not receive ROTATEQ. Cases of gastroenteritis associated with vaccine virus have been reported post-marketing in infants with SCID.

Rotavirus gastroenteritis is the leading cause of diarrheal disease mortality among children under 5 years of age, resulting in an estimated 527,000 deaths per year globally, mostly in Asia and Africa. It is highly prevalent and highly contagious, infecting nearly all children by age 5, often more than once in both developed and developing countries.

“Given the impact of rotavirus gastroenteritis in the developing world, reduction in severe rotavirus disease represents a critically important public health goal,” said Mark Feinberg, M.D., Ph.D., vice president, Medical Affairs and Policy, Merck Vaccines. “Merck is committed to advancing global health by improving access to ROTATEQ in areas most affected by the severe consequences of rotavirus disease.”

In 2009, the World Health Organization’s (WHO) Strategic Advisory Group of Experts recommended to expand rotavirus vaccine use to all regions of the world. The efficacy data for ROTATEQ in Asia and Africa, along with effectiveness data in Nicaragua, helped inform the WHO’s recommendation for expansion of the rotavirus vaccine to all regions. This recommendation led to global WHO-pre-qualification of ROTATEQ, accelerating the availability of vaccines in the developing world.

About the Study

More than 7,500 infants between 4 and 12 weeks of age from five developing countries in Asia (Bangladesh and Vietnam) and Africa (Ghana, Kenya, and Mali) were enrolled in the two-year randomized, double-blind, placebo-controlled clinical trial. The trial was designed to evaluate the efficacy of three doses of ROTATEQ (n=3,751) against severe rotavirus gastroenteritis versus placebo (n=3,753) in low income countries with high incidence of diarrheal disease mortality.

The study was coordinated through a partnership between Merck and the Rotavirus Vaccine Program (RVP), a collaboration between PATH, an international non-profit organization, WHO and the U.S. Centers for Disease Control and Prevention. Clinical trial investigators in Asia and Africa partnered with Merck and RVP to conduct the trial. The Merck and RVP partnership was initiated by the GAVI Alliance in an effort to introduce rotavirus vaccine in the developing world. The study was funded by RVP with a grant from the GAVI Alliance and was co-sponsored by Merck.

In this study, infants received ROTATEQ or placebo at approximately 6, 10, and 14 weeks of age with routine infant vaccines. Infants between 4 and 12 weeks of age who were free of symptoms of active gastrointestinal disease and could be adequately followed for safety were eligible. The primary endpoint was rotavirus gastroenteritis, irrespective of serotype, occurring 14 days or more after the third dose of ROTATEQ or placebo until the end of the study. Gastroenteritis was defined as three or more watery or looser than normal stools within a 24 hour period or forceful vomiting. Severity of rotavirus gastroenteritis was defined by a 20 point clinical scoring system (modified Vesikari system), with those cases with a score of 11 or more being classified as severe.

In Asia, 1,018 infants were randomly assigned to receive ROTATEQ and 1,018 infants received placebo; median follow-up time in both groups, from 14 days after the third dose of vaccine or placebo until final disposition, was 498 days. Over the entire study period, there were 38 cases of severe rotavirus gastroenteritis in the vaccine group, compared with 71 cases reported in the placebo group, resulting in a vaccine efficacy of 48.3 percent (95 percent CI 22.3, 66.1 percent) at sites in Asia. Through nearly two years of follow up, vaccine efficacy was 42.7 percent (95 percent CI 10.4, 63.9 percent) in Bangladesh and 63.9 percent (95 percent CI 7.6, 90.9 percent) in Vietnam.

In Africa, 2,733 infants were randomly assigned to receive ROTATEQ and 2,735 infants received placebo; median follow-up time in both groups was 527 days starting 14 days after the third dose of vaccine or placebo.
Over the entire study period, there were 79 cases of severe rotavirus gastroenteritis reported in the vaccine group, compared with the 129 cases reported in the placebo group, resulting in a vaccine efficacy of 39.3 percent (95 percent CI 19.1, 54.7 percent) at sites in Africa.

Efficacy was 55.5 percent (95 percent CI 28.0, 73.1 percent) in Ghana, 63.9 percent (95 percent CI < 0, 89.8 percent) in Kenya, and 17.6 percent (95 percent CI < 0, 45.0 percent) in Mali through nearly two years of follow up.

In post-hoc analyses, overall efficacy against severe rotavirus gastroenteritis in Asian infants was 51 percent (95 percent CI 12.8, 73.3 percent) in the first year of life and 45.5 percent (95 percent CI 1.2, 70.7 percent) in the second year of life. Efficacy in Bangladesh was 45.7 percent (95 percent CI < 0, 71.8 percent) in the first year of life and 39.3 percent (95 percent CI < 0, 69.7 percent) in the second year of life. Efficacy in Vietnam was 72.3 percent (95 percent CI < 0, 97.2 percent) in the first year of life and 64.6 percent (95 percent CI < 0, 93.9 percent) in the second year of life.

Overall efficacy against severe rotavirus gastroenteritis in African infants was 64.2 percent (95 percent CI 40.2, 79.4 percent) in the first year of life and 19.6 percent (95 percent CI < 0, 44.4 percent) in the second year of life. Efficacy in Ghana was 65.0 percent (95 percent CI 35.5, 81.9 percent) in the first year of life and 29.4 percent (95 percent CI < 0, 70.7 percent) in the second year of life. Efficacy in Kenya was 83.4 percent (95 percent CI 25.5, 98.2 percent) in the first year of life and less than 0 percent (95 percent CI < 0, 82.3 percent) in the second year of life. Efficacy in Mali was 1.0 percent (95 percent CI < 0, 81.6 percent) in the first year of life and 19.2 percent (95 percent CI < 0, 47.3 percent) in the second year of life. The surveillance system in the study protocol was designed to detect participants presenting to healthcare facilities. However, in Mali, for cultural reasons, many cases of severe diarrhea were preferentially taken to traditional healers during the first year of the study. Strengthening of the surveillance system after the first year of the study resulted in a 12-fold increase in detection of severe rotavirus gastroenteritis in Mali in the second year of life, and a higher point estimate of efficacy in the second year than in the first year. The proportion of subjects with reported serious adverse events (SAEs) was comparable between the vaccine and placebo groups in Asia (2.5 percent in ROTATEQ group, 2.0 percent in placebo group) and Africa (1.5 percent in ROTATEQ group, 1.7 percent in placebo group). The most frequent serious adverse event was pneumonia in Asia (1.2 percent in ROTATEQ group, 1.5 percent in placebo group) and gastroenteritis in Africa (0.6 percent in either ROTATEQ or placebo group). One confirmed case of intussusception (in Vietnam), in the placebo group (at Day 97 post-Dose 3), was reported during the clinical trial. “This study provided insights into how vaccine immune responses and efficacy varied in developing countries,” said Max Ciarlet, Ph.D., associate director, Merck Research Laboratories. “Several factors may adversely affect immune response and efficacy of vaccines in these regions, including poor nutrition, the presence of other intestinal bacteria and viruses, and co-infections in the digestive system.” Select Safety Information about ROTATEQ No safety or efficacy data are available from clinical trials regarding the administration of ROTATEQ to immunocompromised patients such as individuals with malignancies or who are otherwise immunocompromised; individuals receiving immunosuppressive therapy; individuals infected with HIV; or individuals who received a blood transfusion or blood products, including immunoglobulins within 42 days. More than 71,000 infants were evaluated in three Phase 3, placebo-controlled clinical trials. Parents/guardians were contacted on days 7, 14, and 42 after each dose regarding intussusception and any other serious adverse events. In the Rotavirus Efficacy and Safety Trial (REST) of more than 69,000 infants, ROTATEQ did not increase the risk of intussusception relative to placebo. There were no confirmed cases of intussesception during the 42-day period after dose one and no clustering of cases among vaccine recipients at any time period after any dose. Four cases of intussusception were reported in children who had received placebo following the one-year safety follow-up period. In a subset of more than 11,000 infants in these trials, the presence of adverse events was reported for 42 days after each dose. The most commonly reported adverse experiences with ROTATEQ (frequency >1/10) include upper respiratory infection, diarrhea, vomiting, pyrexia, otitis media, irritability, and cough.

The following adverse experiences have been spontaneously reported during post-approval use of ROTATEQ: urticaria and gastroenteritis with vaccine viral shedding in infants with SCID. Because these experiences were reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency or to establish a causal relationship to vaccine exposure.

In a prospective post-marketing observational study conducted using a large medical claims database, the risks of intussusception or Kawasaki disease resulting in emergency department visits or hospitalizations during the 30 days following any dose of vaccine were analyzed among 85,150 infants receiving one or more doses of ROTATEQ.

During the 0-30 day follow-up period after vaccination, there were no statistically significant differences in the rates of intussusception or Kawasaki disease compared with the expected background rates. In addition, there was no statistically significant increased risk of these adverse events during the 0-30 day follow-up period when comparing the 17,433 person-years of follow-up among infants receiving ROTATEQ (n equals 85,150) with the 12,339 person-years of follow up among a concurrent control group of infants who received DTaP, but not ROTATEQ (n equals 62,617).

There were six confirmed cases of intussusception among infants vaccinated with ROTATEQ compared with five among the concurrent controls vaccinated with DTaP (relative risk equals 0.8, 95 percent CI 0.22-3.52). There was one chart-confirmed case of Kawasaki disease identified among infants vaccinated with ROTATEQ and one chart-confirmed case of Kawasaki disease among concurrent DTaP controls (relative risk equals 0.7, 95 percent CI 0.01-55.56). In the general safety analyses, the Safety Monitoring Committee did not identify any specific safety concerns.

Cannabis is firm’s ‘gateway drug’

Cannabis is firm’s ‘gateway drug’

Medical pot Has also designed a plant to produce a therapeutic enzyme

Postmedia News August 2, 2010

A reputation of any kind, even for a business, is hard to shake.

And when your company is the only federally licensed medical marijuana producer in Canada, that’s the first thing people think of when they hear the company’s name, says Brent Zettl, Prairie Plant Systems Inc.’s president and CEO.

But providing cannabis to patients authorized by Health Canada isn’t the Saskatoonbased company’s only focus, even if sales of the CanniMed herbal treatment account for between 60 and 65 per cent of its revenue, Zettl says.

“It’s kind of like our gateway drug, if I can use that term,” he says in an interview. “It’s our gateway drug to these other compounds that we’re planning to have produced in plants.”

For nearly 10 years, PPS has produced medical marijuana on a contract basis for the federal government. Originally grown in the deep depths of a decommissioned mine in Flin Flon, Man. -known unofficially as the Ganja Mine -PPS moved its hydroponic operation out of the town on the Saskatchewan border when the contract with the mine’s owner ended last summer.

PPS is still growing the marijuana for the government, but the location of the operation must remain confidential under federal regulations,

Zettl says.

“North of the 49th and in between the Atlantic and the Pacific and Arctic oceans, that’s where it is,” he says.

Although the high-profile, legal and still-controversial practice of growing medical marijuana is what PPS is best known for, Zettl hopes the distinction will change over time.

“I think a lot of people forget this is a contract we bid on,” he says. “But we had a bigger purpose in mind. … Although it’s our reputation at this point, we’re trying to change that.”

The company, along with the Plant Biotechnology Institute, has designed a plant to produce a therapeutic enzyme known as adenosine deaminase, or ADA. The enzyme, Zettl explains, is part of the body’s immune system and is deficient in people with severe combined immunodeficiency disease, a condition often referred to as bubble-boy syndrome.

People with the disease must undergo enzyme-replacement therapy, Zettl says, and at the moment, most of the ADA used in the treatment is purified from cow spleens.

PPS’s ADA takes the animal out of the equation.

The cannabis side of the business, he adds, has helped PPS move forward with its therapeutic enzyme studies, with growing conditions, industry standards and pharmaceutical credibility supporting its scientific work.
