Demodex mites, the microscopic parasites that are normal inhabitants of facial skin, have long raised the question, "Which comes first, Demodex or rosacea?" as medical experts debate whether their increased numbers on rosacea patients are a cause or a result of the disorder. Now there may be some evidence that the "chicken" — Demodex mites — and not the "egg" comes first, according to a recent scientific report.
Some patients who have red scaly faces may in reality have an increased reaction to the Demodex mite rather than rosacea, according to Dr. Joseph Bikowski, clinical assistant professor of dermatology, Ohio State University.
Dr. Bikowski noted that he has treated more than 100 patients with this condition, which involved reaction to these microscopic mites that are normal inhabitants of human skin. In these cases, he reported that patients treated with a topical medication for Demodex cleared within two to four weeks and remained clear for one to two years.
A new study has found there may be a link between ocular rosacea and bacteria associated with Demodex mites, microscopic inhabitants of normal skin that tend to occur in much greater numbers in those with rosacea.
In the recently published study of 59 rosacea patients, Dr. Jianjing Li and colleagues at the Ocular Surface Center in Miami found a significant correlation between facial rosacea, infestation of the eyes with Demodex mites and reaction to certain mite-related organisms previously shown to stimulate an immune response in rosacea sufferers.1
Results of research funded by donations from members of the National Rosacea Society (NRS) are not only increasing medical understanding of the disorder, but are now revealing potential causes that may lead scientists toward important new advances in therapy.
Although they are normal inhabitants of human skin and cannot be seen, microscopic mites known as Demodex folliculorum may actually be something to blush about, as a new study funded by the National Rosacea Society demonstrated for the first time that these invisible organisms may be a cause or exacerbating factor in rosacea.1
In a preliminary study presented during a poster session at the American Academy of Dermatology annual meeting this year, Dr. Richard Burroughs and colleagues of Walter Reed Army Medical Center noted antibiotics may be effective in treating rosacea because of their action against yet-to-be identified bacteria.
The National Rosacea Society (NRS) has awarded funding for six new studies as part of its research grants program to advance scientific knowledge of potential causes and other key aspects of this chronic and often life-disruptive disorder that affects an estimated 14 million Americans.
Five new studies of rosacea have been awarded funding as part of the National Rosacea Society's research grants program to advance scientific and medical understanding of this widespread but poorly understood facial disorder, estimated to affect 14 million Americans.
Researchers reported on continuing progress in the study of potential causes and other key aspects of rosacea during the National Rosacea Society's fourth annual research workshop, held in conjunction with the annual meeting of the Society for Investigative Dermatology.
A severe infestation of microscopic skin mites may mimic rosacea but fail to respond to standard therapy, according to a presentation by Dr. Martin Schaller, assistant professor of dermatology at Ludwig-Maximilians University in Munich, Germany, during the annual meeting of the American Academy of Dermatology.
The tiny mites, known as Demodex folliculorum, are normal inhabitants of human skin. Studies have found an elevated incidence of Demodex in rosacea patients, but it is uncertain whether this is a contributing factor or a result of the disorder.
