Alcon to extend eye drop product lines
HUENENBERG, Switzerland Alcon recently announced that it is releasing two new line extensions this summer across its Systane Lubricant Eye Drops product line.
The product expansions include a dry eye drop for contact lens wearers and a preservative-free, single unit dose product.
Systane Contacts Lubricating Eye Drops, the new moisturizing drop for contact lens wearers, will be shipped in May and is designed to keep eyes comfortable while wearing contacts.
Systane Ultra Preservative Free Vials will launch in August, the company reported. The dry-eye therapy provides extended protection to the ocular surface and increased comfort from the symptoms of dry eye.
“There are over 60 million Americans who suffer from dry eye, and we know they all have different needs,” stated Elyse Dickerson, product manager for Systane. “Expanding our product offering gives consumers more choices for effectively relieving their symptoms with a product designed for their specific needs.”
Study finds link between vitamin D deficiency, bacterial vaginosis
BETHESDA, Md. There may be a link between vitamin D deficiency and bacterial vaginosis, a vaginal infection that is common among pregnant women and can lead to complications.
According to data to be published in the June 2009 issue of the Journal of Nutrition, researchers tracking 469 pregnant women found that 41% of those women had BV, and that the prevalence of BV decreased as vitamin D concentration increased.
Researchers concluded that vitamin D insufficiency is associated with BV in the first four months of pregnancy. Further, poor vitamin D status may contribute to the strong racial disparity in the prevalence of BV in U.S. women. Controlled intervention trials will be needed to confirm this hypothesis, the researchers suggested.
Vitamin D intake can help asthma, COPD patients
SAN DIEGO Vitamin D may slow the progressive decline in the ability to breathe that can occur in people with asthma, as a result of human airway smooth muscle proliferation, according to researchers at the University of Pennsylvania in a study released Wednesday.
The group found that calcitriol, a form of vitamin D synthesized within the body, reduced growth-factor-induced HASM proliferation in cells isolated from both persons with asthma and from persons without the disease. The proliferation is a part of process called airway remodeling, which occurs in many people with asthma, and leads to reduced lung function over time.
The researchers believe that by slowing airway remodeling, they can prevent or forestall the irreversible decline in breathing that leaves many asthmatics even more vulnerable when they suffer an asthma attack.
“Calcitriol has recently earned prominence for its anti-inflammatory effects,” stated Gautam Damera, who presented the research at the American Thoracic Society’s 105th International Conference on Wednesday. “But our study is the first to reveal the potent role of calcitriol in inhibiting ASM proliferation.”
The investigators have also conducted experiments to determine whether calcitriol, which is currently used to treat psoriasis, could be an effective therapy for COPD.
Although preliminary, their data shows that calcitriol appears to reduce pro-inflammatory cytokine secretions in COPD. As with asthma, the researchers believe, calcitriol may also have the added benefit of slowing, if not stopping, the progression of airway remodeling. Others in the field believe calcitriol may also have the potential to inhibit the development and growth of several types of cancer.
