Soon we will have cancer vaccines created under genomic guidance: Dr Pramod K Srivastava

Soon we will have cancer vaccines created under genomic guidance: Dr Pramod K Srivastava

In an interview with ETHealthworld, Dr Pramod K Srivastava, Prof & Director of the Centre for Immunotherapy of Cancer & Infectious Diseases, Connecticut, US, talks about the role and opportunities in genomic research and the making of cancer vaccine.

You have been associated with clinical research right from the 90s. Tell us about the opportunities that genomics offers today?

Around 1990's there was no genomics in cancer immunology or cancer immunotherapy. The whole idea of genomics coming into it has come about only in the last 5 or 6 years because only then could we look at the entire genome of a patient.

What we can do today is to take the cancer of a patient, take their normal tissues and read the entire genome both normal and the cancerous within a week and we can compare how it is different within another week. So basically in two weeks time in surgery or from biopsy we can pinpoint all the positions where this cancer is different from the normal tissue.

This capacity didn't exist in a practical way until 2008-2009 but now sequenced genome is pretty much at the cost of a MRI scan, little more than that. Today, it is like a whole different world with different languages, different level of precision and different levels of possibilities.

Can cancer vaccine be a reality today?

Cancer vaccines are certainly not a reality today but it could they be a reality in 10 years time. It is not a question of if but it is a question of when and how and where. The way we treat cancer today is not very effective.

Today in terms of outcome there isn't much of difference and the reason is that the things that we use for these treatments like chemotherapy and surgery they don't discriminate between normal tissues and cancers in any real way. It kills cancers and normal tissues also and the whole goal is to traverse that very normal lane and damage the cancer more than damaging the normal tissue.

Isotretinoin in India: A tragedy in the offing

Isotretinoin in India: A tragedy in the offing

Isotretinoin is the drug of choice for severe calcitrant cystic acne vulgaris, which often causes scarring and depression from disfigurement. Isotretinoin has been called "the greatest medical advance of the 1980's." A majority of patients with acne are permanently cleared after a four to five months course of treatment. It has also been used off-label for a variety of oncology uses including: cervical cancer, head and neck cancer, squamous cell cancer of the skin, juvenile chronic myelogenous leukemia (CML), and neuroblastoma. However, the drug is a proved teratogen and carries a significant risk of birth defects, if it taken during pregnancy. Birth defects, which have been documented following isotretinoin exposure include abnormalities of the face, eyes, ears, skull, central nervous system, cardiovascular system, and thymus and parathyroid glands. There is an increased risk …

FDA Restricts Use of Diabetes Drug Avandia

FDA Decides Not to Ban Avandia, but Puts Restrictions on How It’s Used.

WebMD Health News

Sept. 23, 2010 -- The FDA will not ban Avandia -- but stringent restrictions will make it far harder for doctors to prescribe the safety-troubled diabetes drug.

The European Medicines Agency took harsher action. European sales of Avandia-containing drugs will be suspended over the next few months, although the agency did not formally withdraw approval.

The 600,000 U.S. patients currently taking Avandia can continue to take the drug only if their doctors officially attest that their patients understand the risks, that the drug is helping them, and that no other diabetes drug can keep their blood sugar under control.

New Avandia prescriptions can only be written for patients who, for medical reasons, cannot take Actos. Actos, a diabetes medication in the same class as Avandia, does not cause the heart problems linked to Avandia.

"Avandia will be available to new pat…

The Connection Between Sedatives and Fractures in Elderly Patients

The Connection Between Sedatives and
Fractures in Elderly Patients
All drugs have potential side effects. Indeed, at some point you've probably squinted down the laundry list of possible side effects on the package insert of your medications. Common drug-related side effects include blurred vision, drowsiness, dizziness, dry mouth, heart palpitations, erectile dysfunction, memory impairment, and nervousness. Fortunately, many of these drug side effects occur in only small numbers of people. Now researchers have called into question the connection between sedatives which can cause dizziness and the potential for falls in elderly patients. They point out that well-meant policies discouraging sedative use in older people to prevent falls and fractures may not be necessary. Starting in 1989, New York State required doctors to fill out prescriptions in triplicate for benzodiazepines, the most widely used class of sedatives. Tw…
