‘Bleach bath’ benefit for eczema

Child with eczema

Eczema causes red, itchy, inflamed patches on the skin

Adding bleach to the bath may be an effective treatment for chronic eczema, US researchers say.

In a study of 31 children, there was significant improvement in eczema in those who had diluted bleach baths compared with normal baths.

The Pediatrics study also showed improvements were only on parts of the body submerged in the bath.

UK experts stressed the treatment could be extremely dangerous and should only be done under the care of a specialist.

Children with bad eczema suffer from chronic skin infections, most commonly caused by Staphylococcus aureus, which worsen the eczema that can be difficult to treat.

Some children get resistant MRSA infections.

Studies have shown a direct correlation between the number of bacteria on the skin and the severity of the eczema.

It has been shown that bacteria cause inflammation and further weaken the skin barrier.

In the study, researchers randomly assigned patients who had infection with Staphylococcus aureus to baths with half a cup of sodium hypochlorite per full tub or normal water baths for five to 10 minutes twice a week for three months.

They also prescribed a topical antibiotic ointment or dummy ointment for them to put into their nose – a key site for growth of the bacteria.

Eczema severity in patients reduced five times as much as those on placebo.

But there was no improvement in eczema on the head and neck – areas not submerged in the bath.

Rapid improvement

“We’ve long struggled with staphylococcal infections in patients with eczema,” said study leader Dr Amy Paller, from Northwestern University in Chicago.

She added they saw such rapid improvement in the children having bleach baths that they stopped the study early.

“The eczema kept getting better and better with the bleach baths and these baths prevented it from flaring again, which is an ongoing problem for these kids.

“We presume the bleach has antibacterial properties and decreased the number of bacteria on the skin, which is one of the drivers of flares.”

Professor Mike Cork, head of dermatology research and a consultant at Sheffield Children’s Hospital, said antiseptic baths had been used as a treatment for eczema for quite a while but the trial was important because it highlights the benefits from reducing bacteria.

“But people should not start putting bleach in their children’s bath.

“Bleach used incorrectly could cause enormous harm to a child with atopic eczema while, in the hands of an expert, it can as this trial indicates lead to benefit.”

He added the trial highlighted the need for children with uncontrolled eczema to be referred to a specialist for treatment.

Patients Using Retinoid Cream More Likely To Die

How scratching can stop an itch

Itching

Nerve cells play a key role in itching

Scientists have shown scratching helps relieve an itch as it blocks activity in some spinal cord nerve cells that transmit the sensation to the brain.

However, the effect only seems to occur during itchiness itself – scratching at other times makes no difference.

While it is widely-known scratching relieves an itch, the physiological mechanisms for how this works are little understood.

The University of Minnesota study appears in Nature Neuroscience.

We all know that scratching helps alleviate itch, but this elegant study helps to show how this mechanism works
Professor Patrick Haggard

Previous research has suggested that a specific part of the spinal cord – the spinothalamic tract – plays a key role.

Nerve cells in this area have been shown to be more active when itchy substances are applied to the skin.

Blocks activity

The latest work, in primates, found that scratching the skin blocks activity of nerve cells in the spinothalamic tract during itchiness – preventing the spinal cord from transmitting signals from the scratched area of skin to the brain.

ITCHING
There are many causes of itch, including more than 50 diseases including shingles, Aids, gallbladder problems and Hodgkin’s Disease
The itch produced by many diseases can greatly affect quality of life and can not be treated currently
For many types of itch, it is not clear that itch serves any clear purpose

Researcher Dr Glenn Giesler hopes the work could lead to ways to relieve chronic itch effectively for the first time. However, he said more information was still needed about the chemistry underpinning the effect.

Professor Gil Yosipovitch, an expert on itching from Wake Forest University in North Carolina, said the finding was “potentially significant”.

He said: “Although there is a long way to go, methods that can induce a pleasurable scratch sensation without damaging the skin, via mechanical stimuli or drugs that can inhibit these neurons, could be developed to treat chronic itch.”

However, Professor Yosipovitch stressed that scratching and itching were complex phenomena involving factors such as emotions as well as physiology.

“The main open question is what happens in patients who suffer from chronic itch where scratching may actually aggravate itch perception.”

Professor Patrick Haggard, of University College London, said: “We all know that scratching helps alleviate itch, but this elegant study helps to show how this mechanism works.

“It’s an interesting illustration of a very general principle of the brain controlling its own inputs, in this case by making movements that triggers an interaction between scratchy touch and itch.”

Dr Paul Bays, based at UCL’s Institute of Cognitive Neuroscience, agreed that the study provided an important part of a physiological explanation for how the sensation of itch is reduced.

“However, it is still unclear why scratching should have this effect, or why it is only effective for itches and not for painful sensations – which are transmitted to the brain through the same pathway.”


A clinical trial was halted when it was found that patients who use a cream containing tretonoin – a retinoid used for treating acne and other skin conditions – had a higher chance of dying, compared to patients who used a placebo, according to an article in Archives of Dermatology. However, evidence does not seem to suggest that the therapy caused the extra deaths.


Psoriasis Patients May Gain Valuable Support From Virtual Communities

Tuesday 20 January 2009 1:00 am

According to Archives of Dermatology, psoriasis patients receive valuable educational, psychological and social support from online support communities. Archives of Dermatology is a JAMA (Journal of the American Medical Association) journal. The article explains that about 0.6% to 4.8% of the world’s population is currently affected by psoriasis.
