Blood clotting (thrombosis) in the capillary vessels of the lungs is one of the first consequences of severe Covid-19, even preceding the respiratory distress caused by diffuse alveolar damage, according to a study. The study, published in the Journal of Applied Physiology, described autopsies of nine patients who died after developing the severe form of the disease showed a clearly typified condition involving alterations to lung vascularisation and thrombosis. For the first time, the [...]

Ageing is known to increase the production of an immune protein that may harmfully react with a person's own tissues or organs. But researchers have now found that Covid-19 infection can exacerbate their production, explaining why old age raises the odds of developing severe Covid. Increases in the immune protein, known as auto-antibodies, may also lead to blood clotting disorders such as thrombosis, showed the study, published in the journal npj Aging. "These findings open the [...]

A team of Brazilian researchers has discovered that a gene can protect people, even those aged 90 and above, from the deadly Covid disease. Two research papers found that the frequency of variants of the gene 'MUC22' was twice as high in the mild Covid-19 group as in severe patients, and higher still in resilient super-agers. This gene belongs to the "mucin" family and is associated with the production of mucus, which lubricates and protects the airways. On the other [...]

Sao Paulo, Aug 18: Patients with the most severe post-Covid smell and taste disorders are likely to perform worst in cognitive tests, especially when these involve memory, finds a study strengthening the hypothesis that loss of smell could be an early sign of the impending onset of Alzheimer’s disease. In the study, a group of Brazilian researchers analysed clinical data from 701 patients hospitalised for moderate or severe Covid-19. The results, reported in European Archives of [...]

Sao Paulo, June 24 (Ajit Weekly News) In a rare case, Brazilian scientists used breast milk to treat Covid-19 in a woman with a rare genetic disease that makes her immune system unable to combat viruses and other pathogens. The patient who was diagnosed with Covid-19, in March 2021, tested positive for 124 days by RT-PCR. She was advised by the team from the University of Campinas (UNICAMP) in Sao Paulo, to take 30 millilitres of breast milk every three hours for a week. The breast milk was [...]
