A cure for HIV? Case studies show feasible treatments not yet realised

Image
This week a team of scientists and physicians from the U.K. published news of a second HIV positive man, in London, who is in long-term (18-month) HIV remission after undergoing treatment for Hodgkins lymphoma. The unexpected success has launched a new round of discussion about a potential cure for HIV. Since 2008, scientists have been trying to replicate the treatment that cured the “Berlin patient” of HIV. At the time, many in the field of HIV research were excited to learn that this man, who tested positive for the human immunodeficiency virus in Berlin and had recently undergone treatment for acute myeloid leukemia, appeared to have been cured of his HIV. Until now, success in replicating that cure has been limited. What is HIV? HIV is the virus that causes AIDS . Since the virus was first discovered in the 1980s, more than 75 million people worldwide have been infected with HIV. Today, almost 37 million people live with HIV. Of these, about 1.1 million live in the U.S.

Major breakthrough in treatment of AIDS: Second patient cured of HIV

Image
Researchers say a London man appears to be free of the AIDS virus after a stem cell transplant. It's the second such success including "Berlin patient" Timothy Ray Brown. Such transplants are dangerous and have failed in other patients. The new findings were published online Monday by the journal Nature. The London patient has not been identified. He was diagnosed with HIV in 2003. He developed cancer and agreed to a stem cell transplant to treat the cancer in 2016. His doctors found a donor with a gene mutation that confers natural resistance to HIV . The transplant changed the London patient's immune system, giving him the donor's HIV resistance.

Marijuana edibles pose major risk to elderly patients with cardiovascular disease

Image
With marijuana being legalised across North America, there is a changing perception that sees people believing that weed is the safest recreational drug. However, those assumptions are now challenged in an article in the Canadian Journal of Cardiology that examine the story of a patient who developed chest pain and myocardial ischemia after consuming most of a marijuana lollipop. Speaking about it, expert Alexandra Saunders said, "Marijuana can be a useful tool for many patients, especially for pain and nausea relief . At the same time, like all other medications, it does carry risk and side effects. In a recent case, inappropriate dosing and oral consumption of marijuana by an older patient with stable cardiovascular disease resulted in distress that caused a cardiac event and subsequent reduced cardiac function." According to the report, a 70-year-old man with stable coronary artery disease, taking appropriate cardiac medications at most of a lollipop infused w

'HIV counselling, test centres in Delhi lack privacy'

Image
Privacy of patients who go for HIV testing and counselling in the national capital's government hospitals remains a prime concern as many of them don't have separate counselling rooms for males and females, a study has found. The study, titled "Integrated Counselling and HIV Testing Centres of Delhi: An Evaluation", by Dr Anita Khokhar, Director Professor, Community Medicine, Vardhman Mahavir Medical College and Safdarjung Hospital, along with Dr Vinoth Gnana Chellaiyan of the Department of Community Medicine at Chettinad Hospital and Research Institute, Kelambakkam, Chennai, revealed that a majority of the Integrated Counseling and HIV Testing Centres (ICTCs) in the national capital lacked separate rooms for male-female counselling and nor was there adequate space inside the allocated room. According to the National AIDS Control Organisation (NACO), 93 medical facilities under the Centre and the state governments in Delhi have ICTCs. Eleven medical fac

World's first gene-edited babies? Premature, dangerous and irresponsible

Image
A scientist in China claims to have produced the world’s first genome-edited babies by altering their DNA to increase their resistance to HIV . Aside from the lack of verifiable evidence for this non peer-reviewed claim, this research is premature, dangerous and irresponsible. He Jiankui from the Southern University of Science and Technology in Shenzhen (which has reportedly since suspended him) said he edited the DNA of seven embryos being used for fertility treatment, so far resulting in the birth of one set of twin girls. He says he used the tool known as CRISPR to delete the embryos’ CCR5 gene (C-C motif chemokine receptor 5), mutations in which are linked to resistance to HIV infection . If true, this is a significant advance in genetic science, but there are some very serious problems with this news. First, the research has not yet been published in a peer-reviewed journal so we cannot be sure of the exact details of what has been done. Instead, the scientist made

Blood not needed if you're gay: The stigma attached to Mumbai blood banks

Image
Despite a landmark verdict on Section 377 by the Supreme Court, which decriminalised gay sex in the country, the Maharashtra arm of National Blood Transfusion Council (NBTC) recently issued a newly-updated blood donor screening questionnaire to Mumbai-based blood banks. The new questionnaire, designed on the lines of developed nations, will now mandate the blood collectors to ask the male donors about their sexual behaviour and whether they have multiple partners or engaged in the male-to-male sexual activity. For decades, the ban on homosexuals to donate blood exists in India and those who are at high risk of suffering from prolonged diseases such as cancer, allergies, respiratory ailments and organ failure are also not allowed to donate blood.

India sees major reduction in HIV infections but challenges remain: UN

The report underscored the public health benefits of decriminalising sex work Health News : India saw a major reduction in the number of new HIV infections, AIDS-related deaths and people living with HIV from 2010 to 2017 on the back of sustained and focussed efforts, according to a UN report which warned that the epidemic was growing in Pakistan. The Joint UN Agency on AIDS (UNAIDS) report titled 'Miles to go closing gaps, breaking barriers, righting injustices' said Asia and the Pacific regions have made strong inroads with its HIV response. Sustained and focused efforts to reach key populations have led to major reductions in HIV infections in Cambodia, India, Myanmar, Thailand and Vietnam between 2010 and 2017. The report, however, warned that the global new HIV infections were not declining fast enough. It also noted that the epidemics were expanding in Pakistan and the Philippines. In India, new HIV infections dropped from 120,000 in 2010 to 88,
