Soak in salt water bath to ease arthritis

Scientists have a simple way to battle the agony of arthritis - soaking in a bath of salt water.

They say the saline solution reduces painful inflammation of the joints.

Even ordinary table salt in high concentrations can be used and, unlike conventional drugs, there are no unpleasant side effects.

"This research opens up exciting opportunities. What we've identified has the potential to be used to help so many patients," the Daily Express quoted Vincent Compan, of Manchester University's Faculty of Life Sciences, as saying.

Dr Compan and Dr Pablo Pelegrin found cells in the bodies of arthritis sufferers expand but salt water can reduce the swelling by dehydrating them. The salt worked the same whether it was injected into the body or absorbed through the skin via bandages soaked in saline or bathing.

"We have found that hypotonic solutions (low in salt) strongly activate inflammation at molecular level. Conversely, the use of hypertonic solutions (high in salt) was a potent inhibitor of such inflammatory signals at molecular level," Dr Pelegrin said.

"Therefore, osmotherapy (dehydration) with hypertonic solutions could be beneficial in the management of inflammatory joint diseases, such as rheumatoid arthritis, either by prolonged soaking or by vapour pressure techniques," he noted.

The results were published in the journal Immunity.

Men and women different when it comes to illness

Men and women do not have the same propensity to develop certain diseases, researchers have shown.

Everyone is not the same when it comes to illness. In fact, the risk of developing a disease such as diabetes or heart disease varies from one individual to another.

A study led by Emmanouil Dermitzakis, Louis-Jeantet Professor at the Faculty of Medicine of the University of Geneva (UNIGE), reveals that the genetic predisposition to develop certain diseases may differ from one individual to another depending on their sex.

Together with his collaborators, the professor has shown that genetic variants have a different impact on the level of gene expression between men and women.

For decades geneticists have been interested in genetic variants that affect the level of gene expression. These variants spark the interest of researchers because they play a role in the predisposition to certain diseases.  Professor Dermitzakis' team from UNIGE, in collaboration with Oxford University, focused on the fundamental differences in the genetics of gene expression between men and women.

After analyzing the impact of genetic variants on the level of gene expression in women, and then in men, the scientists have found that the effect of certain variants affecting gene expression and the genetic risk of developing a disease resulting from these genetic variants is different depending on the sex of the individual.

The researchers found that even with the same DNA mutation in men and in women, the impact on the level of gene expression will be different. Of all the genetic variants that have an impact on the level of gene expression, about 15 per cent work differently depending on whether they are acting upon a man or a woman.

"We already knew that certain environmental factors like diet had a variable impact depending on the sex of an individual," Professor Dermitzakis said.

"Today, we are able to confirm that genetic variants have a different impact on the level of gene expression in men and women; that is to say that although two individuals of opposite sex both have a same variant predisposing them to a disease, they will not have the same propensity to develop it," Professor Dermitzakis added.

The study has been published in the scientific journal Genome Research.
