    Rosacea Research

    Rosaceans can make a difference in rosacea research by joining the RRDi as a corporate member. Please join and VOLUNTEER

    The RRDi could engage in some novel rosacea research. You can become involved with this volunteer movement of rosaceans making a difference in the direction of rosacea research. Never underestimate the power of rosaceans volunteering. For example, you could volunteer as a grant writer (if you have no experience you could learn how). If you are a professional grant writer, or would like to learn how to write grants for rosacea research, please click here.

    Joel T. Bamford, M.D., wrote an article in the Journal of the RRDi entitled, "Is it possible for rosaceans to do research?" The answer to that question is joining our cause and making this possible. The RRDi is in the forefront of the medical digital revolution which you can be a part of. For more information click here.

    "However, as another important outcome, their analyses also highlighted the need for better-quality studies evaluating treatments for rosacea....The reviewers also found there were no randomized, controlled trials evaluating other treatments commonly used for rosacea, including doxycycline, minocycline, isotretinoin, laser therapy, erythromycin, dapsone and topical tretinoin." [1]

    According to Michael Detmar, M.D., in 2003, only one paper was published for every 144,000 rosacea patients in the United States, compared to a 1-to-11 ratio for melanoma and 1 to 4,900 for psoriasis. [Source]

    RRDi Education Grants

    The RRDi has funded educational grants sponsored by Galderma. For more information click here.

    Volunteer

    If you want to become involved as a volunteer you can begin to educate yourself with the following subjects on rosacea research:

    Rosacea Research in Perspective of Idiopathic Diseases

    Rosacea Research in Perspective of Funding

    Rosacea Research Forum

    Rosacea RRDi Research Articles

    Call For Papers - Journal of the RRDi. Volume 2, No. 1

    Rosaceans Funding Rosacea Research
    Could 10K members of the RRDi get together and each donated one dollar and fund a double blind, placebo controlled, peer reviewed clinical study research paper on rosacea? Only if you become involved. That is what volunteering is all about. Donate.

    • "Rosacea is a common inflammatory skin disorder mediated by the dysregulation of both keratinocytes and T cells. Here, we report that aquaporin 3 (AQP3), a channel protein that mediates the transport of water/glycerol, was highly expressed in the epidermis and CD4+ T cells of both rosacea patients and experimental mice....Our findings reveal that AQP3-mediated activation of NF-κB in keratinocytes and activation of STAT3 in CD4+ T cells acted synergistically and contributed to the inflammation in rosacea." [1] "Aquaporin 3 (AQP-3) is the protein product of the human AQP3 gene." [2] "Aquaporins (AQPs) are water channels that facilitate transepithelial water transport across plasma membranes following an osmotic gradient [3]. AQPs are glycosylated integral membrane proteins and widely expressed in bacteria (for review [4]), yeast [5], plants [6] (for review [7]), and mammals..." [3] Obviously we need more rosacea research on this subject. Do you want to support such targeted research? Join the RRDi and post in this thread.

    • "In fact, rosacea might be underreported and underdiagnosed in populations with skin of color because of the difficulty of discerning erythema and telangiectasia in dark skin. The susceptibility of persons with highly pigmented skin to dermatologic conditions like rosacea, whose triggers include sun exposure, is probably underestimated. Many people with skin of color who have rosacea might experience delayed diagnosis, leading to inappropriate or inadequate treatment; greater morbidity; and uncontrolled, progressive disease with disfiguring manifestations, including phymatous rosacea."

    • In  2004, it has been stated that "The economic burden of skin disease on the US healthcare was approximately $96 billion in 2004. [1] "In 2013, more than 85 million Americans were seen by a medical professional for skin diseases. The United States healthcare system alone is estimated to spend approximately 75 billion dollars annually to treat skin diseases. Additionally, the prevalence of skin disease increases to almost 50% in Americans 65 years of age or older). Moreover, it is estimated that the population over the age of 65 will almost double in the United States in the next 30 years, leading to an inevitable increase in annual healthcare costs for skin disease treatment." [2] This expenditure is on all skin conditions. A "Data Bridge Market Research analyses that the rosacea treatment market, which was USD 1.8 billion in 2022, would rocket up to USD 2.6 billion by 2030 and is expected to undergo a CAGR of 6.1% during the forecast period of 2023 to 2030." - Global Rosacea Treatment Market, DBMR  How much is spent on rosacea in the USA?  Rosacea How many of those billions are spent on rosacea? As the above figures shows it is in the millions of dollars.  "In 2013, the costs associated with the treatment and lost productivity among those who sought medical care for rosacea was $243 million." [2] Between 2002 and 2005, for an individual patient, "Of the total healthcare costs, annual rosacea-related expenditures were $276; approximately 70% of rosacea-related expenditures were due to prescription drugs. [3]  In 2013, "The treatment of rosacea incurred primarily pharmacy rather than medical costs. The median annual pharmacy costs, by type of therapy, were: $285 for combination therapy $142 for a topical medication $63 for an oral antibiotic agent." [4] In 2014, the NRS states, "The lack of health insurance or the amount of the required co-pay kept 47 percent of the survey respondents from obtaining medical care for their rosacea at some point.  And 56 percent reported they had paid out-of-pocket for a rosacea-related medication or procedure not covered by their insurance policy.  Of those answering the survey, the amount paid out of pocket was less than $100 for 33 percent, between $100 and $500 for 35 percent, between $500 and $1,000 for 12 percent and greater than $1,000 for 11 percent."
