A recent NRS-supported study in twins has found a significant correlation between severity of rosacea and facial bacterial dysbiosis, potentially providing a basis for future research into what causes rosacea and how to treat it.

While avoidance of trigger factors, gentle cleansing and a variety of medical therapies are among today’s options for controlling ocular rosacea, continuing research on its pathophysiology is uncovering potential avenues for the development of important new advances in its treatment, according to Dr. Edward Wladis, associate professor and vice-chairman of ophthalmology at Albany Medical College, in a recent article in the medical journal Survey of Ophthalmology.¹

The National Rosacea Society (NRS) has awarded funding for three new studies, in addition to continuing support for three ongoing studies.

A recent study in the European Journal of Dermatology investigated the possible connection between rosacea and insulin resistance.

Researchers conducting a nationwide study in Denmark found that rosacea may be associated with increased risk of certain gastrointestinal (GI) diseases, but whether there is a cause-and-effect relationship is unknown.

The National Rosacea Society has awarded funding for three new studies, in addition to continuing support for two ongoing studies, as part of its research grants program. The purpose of the grant program is to increase knowledge and understanding of the causes and other key aspects of rosacea that may lead to improvements in its management, prevention or potential cure.

Two recent small studies on ocular rosacea yielded new findings that help in understanding its manifestations as well as the disease process.

Researchers at Kirikkale University in Turkey found that despite a high incidence of dry eye in individuals with rosacea, corneal and conjunctival sensitivity were not significantly different from those of the eyes of individuals without the disorder. This is the first time to their knowledge that such a study has been conducted.¹

The surge of scientific studies linking rosacea and a wide variety of other medical disorders, called comorbidities, may have been inspired by similar findings about another skin disorder, according to Dr. Sewon Kang, chairman of dermatology at Johns Hopkins School of Medicine and a member of the NRS Medical Advisory Board.

Physicians and researchers may soon have a new computer-based process to help objectively assess the redness of subtype 1 (erythematotelangiectatic) rosacea, according to a recent report by researchers from the University of California-Davis.

Right now, the redness of rosacea is typically assessed visually by dermatologists using various scales to evaluate severity, such as the Clinician’s Erythema Assessment, a standard scale that has been demonstrated to be reliable in determining agreement among visual evaluations. Current assessments may also be assisted by photography.

Kallikrein-related peptidases (KLKs), a family of proteases recently identified as having a possible role in the development of rosacea, may help provide a pathway to controlling rosacea’s signs and symptoms, according to an article by Drs. Jan Fischer and Ulf Meyer-Hoffert of the University Hospital Schleswig-Holstein in Germany in the journal Thrombosis and Haemostasis.
