Flu and diabetes linked

Pubblicato il 05/11/2012Read time: 1 min

A link between influenza A virus and type 1 diabetes has been discovered by the research team led by Ilaria Capua, group leader of the World Organisation for Animal Health reference laboratory for avian flu in Legnaro, Italy.

Type 1 diabetes often appears suddenly after an infection and is caused by an inflammatory response that targets the pancreatic cells that produce insulin, destroying them. For these reasons, a connection between this disease and a viral trigger has been hypothesized in the last 40 years, but nobody managed to demonstrate it.

Capua’s team tested this hypothesis in vivo on an avian model and in vitro on human pancreatic cell lines; they found that influenza infection may lead to pancreatitis and diabetes in humans and other mammals. A further confirmation of these results seems to come from several reports from Japan and Italy of many newly diagnosed cases of type 1 diabetes in people who had recently had flu, and an increase in type 1 diabetes after the 2009 swine flu pandemic.

The embarrassing Covid

di Stefania Salmaso

Pubblicato il 02/10/2023

There's a certain discomfort in having to talk about Covid-19 again, as demanded by the increase in cases that is also recorded in Italy. The reason, writes epidemiologist Stefania Salmaso, might perhaps be identified in the lack of a transparent process that allows understanding on what basis the health authority formulates recommendations, leading to reliance on pundits.

Epidemiology

“An embarrassing Covid-19”: It could be the title of a short story by Calvino or a rhyme by Rodari, but it's what we're witnessing these days. The increasing frequency of SARS-CoV-2 infections in various areas of the world, including Italy, has forced mainstream media to address it again. However, it's often discussed with a sort of embarrassment and only for the sake of reporting. When discussing possible countermeasures, the discomfort becomes even more apparent.
