Viagra 'a possible solution' to treat oxygen-deprived newborns: Study

Published

on

Toronto, Feb 16 (IANS) Viagra, primarily known as an erectile dysfunction drug, may also help treat babies who run out of oxygen during pregnancy or at birth (neonatal encephalopathy), according to a study.

Options to treat oxygen-deprived newborns are limited. Therapeutic hypothermia is the only option used to prevent brain damage in such cases, but 29 per cent of babies who receive it still develop significant neurological sequelae.

A team of researchers at the Montreal Children’s Hospital (MCH) in Canada, in a new clinical study showed that the administration of sildenafil, marketed under the brand name Viagra, could be a possible solution.

“This is the first proof-of-concept study to attempt to repair the brain damage caused by neonatal encephalopathy,” said the team.

Using sildenafil in babies with such sequelae despite therapeutic hypothermia was found “feasible and safe”.

“Currently, when a baby has brain damage, there is little we can offer other than supportive care such as physiotherapy, occupational therapy or specialised care. If we had a drug that could repair the brain, it could change the future of these babies. It would be a victory for them, for their family and for society in general,” said Pia Wintermark, neonatologist at the MCH.

Previous research in rat models showed that sildenafil can have neurorestorative properties in adult stroke patients. The team therefore thought of experimenting its effects on the brains of newborn babies.

The first phase of the clinical study involved 24 babies born at 36 weeks of gestation or more, with moderate to severe neonatal encephalopathy, who had been placed on therapeutic hypothermia and had brain damage despite treatment.

Of the group, eight received sildenafil starting on the second or third day of life, twice a day for seven days (total of 14 doses). A placebo was administered to three other babies.

In two of the eight babies, blood pressure slightly decreased after the first dose of sildenafil, but this did not recur thereafter, while no child in the placebo group died.

“The study therefore concludes that sildenafil is safe and well absorbed by babies who have developed brain damage due to neonatal encephalopathy and in whom therapeutic hypothermia has proved ineffective,” the team said.

Further, in an exploratory analysis, five newborns treated with sildenafil showed partial healing of injury, fewer signs of brain volume loss and an increase in deep gray matter at 30 days of age. Nothing of the kind was noted in the placebo group.

Nine out of ten patients were also seen at 18 months for neurodevelopmental evaluation.

In the sildenafil group, one baby in six developed cerebral palsy, compared to three babies in three in the placebo group. Global developmental and fine motor delays were noted in two out of six children given the drug, while all children in the placebo group (3/3) suffered from them.

“All neonates enrolled in this study had significant brain damage at baseline. As such, it was expected that they would develop poorer neurodevelopmental outcomes compared with a general population of neonates with neonatal encephalopathy treated with therapeutic hypothermia,” Wintermark said.

“Sildenafil is inexpensive and easy to administer. If it holds its promise in the next phases of the study, it could change the lives of babies suffering from neonatal encephalopathy all over the world,” the researcher said.

Mice with functional humanised immune system shows promise

Published

on

By

New Delhi, July 6 (IANS) A first-of-its-kind mice model with a fully functional human immune system and a human-like gut microbiome has shown promise of mounting specific antibody responses.

To date, researchers have not developed a fully functional human immune system, but only those with a brief lifespan that do not mount efficient immune responses, making them unsuitable for the development of in vivo human immunotherapies, human disease modelling, or human vaccine development.

Developed by scientists at The University of Texas in the US, the new model will overcome limitations of currently available in vivo human models and is a breakthrough for biomedical research and promises new insight into immunotherapy development and disease modelling.

Detailed in the journal Nature Immunology, the new humanised mice, called TruHuX (for truly human, or THX), possess a fully developed and fully functional human immune system, including lymph nodes, germinal centres, thymus human epithelial cells, human T and B lymphocytes, memory B lymphocytes, and plasma cells making highly specific antibody and autoantibodies identical to those of humans.

THX mice mount mature neutralising antibody responses to Salmonella Typhimurium and SARS-CoV-2 virus Spike S1 RBD after vaccination with Salmonella flagellin and the Pfizer Covid-19 mRNA vaccine, respectively.

It is also amenable to developing full-fledged systemic lupus autoimmunity after an injection of pristane — an oil that triggers an inflammatory response.

“THX mice provide a platform for human immune system studies, development of human vaccines, and testing of therapeutics,” said Paolo Casali, Professor at the University of Texas School of Medicine in San Antonio, US.

They do this “by critically leveraging oestrogen activity to support human stem cell and human immune cell differentiation and antibody responses”, he added.

Mobile tariff hike: Centre responds to misleading claims

Published

on

By

New Delhi, July 6 (IANS) The government has responded to misleading claims regarding recent mobile services tariff hike, saying with three private and one public sector player, the current mobile services market operates through the market forces of demand and supply.

The Telecom Regulatory Authority of India (TRAI) said the rates of telecommunication services are decided by market forces, within the regulatory framework notified by the independent regulator.

“The government does not intervene in the free market decisions as the functionality is under the domain of TRAI and tariffs are under forbearance,” said the regulator.

The TRAI said the telecom service providers (TSPs) have increased the prices of mobile services after more than two years.

“In the last two years, some of the TSPs have invested heavily in rolling out the 5G services across the country. This has resulted into a significant increase in median mobile speed to the level of 100 Mbps and jump in India’s international rank from 111, in October 2022, to 15 today,” the TRAI explained.

While protecting the interests of subscribers, for the orderly growth of the telecommunication sector, which includes investments in latest technologies like 5G, 6G, IoT/ M2M for Industry 4.0 etc., “the financial viability of the sector is important,” said the TRAI.

Before last 10 years, the telecommunication sector was mired in controversies, lack of transparency and therefore, growth of mobile services was stagnant.

“During the last 10 years, due to progressive policies of the government, the rates of telecommunication services be it voice or data, have fallen exponentially,” said the telecom regulatory body.
