    The purpose of the Rosacea Research & Development Institute [RRDi] is to fund research and development for finding a cure for rosacea by establishing a Medical Advisory Committee [MAC] of the best available minds on rosacea and to publish the results of this endeavor to the public and professional groups. This MAC will provide the direction of the research. Research may also include studying various treatments for the control of rosacea in multi-center, double blind, placebo controlled clinical trial studies. The RRDi is commited to support patient advocacy for those suffering from rosacea. This organization is open to the public and membership is free and has been organized by rosaceans for rosaceans. This organization is a non-profit corporation registered in the State of Hawaii and 501 (c) (3) tax-exempt status approval has been obtained from the IRS effective June 7, 2004. The Articles of Incorporation, the Bylaws, and the Conflict of Interest Policy are available for the public.

    Membership is open to the public and is free for volunteers. Rosaceans are specially invited to join. All who join providing contact information become members of the corporation and for now this number is not limited but may be revised in the future by the institute. There are two categories of members: 

    Voting Member (a member who choses voluntarily to provide contact information, i.e., first and last name, mailing address and phone number, email addresses) and has a diagnosis of rosacea. 

    Non Voting Member (a member who only provides one email address).

    An Active Member is one who has posted within the last thirty days and has full access to the RRDi website. An Inactive Member is one who has not posted in the last thirty days and is therefore restricted to guest privlieges of access to the site until such time as the member becomes active again and full access to the site is restored. Any SUBSCRIBED member is not restricted to post within thirty days and may or may not post as long as the subscription is active. Volunteer Active Members may waive the subscription fee as long as they post at least once a month.  

    A rosacean is anyone who is diagnosed by a physician as having rosacea. All that is necessary to be designated a voting member is a statement from the member that a diagnosis of rosacea has been obtained from a physician as well as the contact information mentioned above for voting members. Voting members should be rosacea sufferers (rosaceans). 

    Non-rosaceans are permitted to join and should identify themselves as such upon demand from the institute. Non-rosaceans are those who have not obtained a diagnosis of rosacea by a physician. 

    Any member of the institute may be removed from the membership at any time at the sole discretion of the institute. Rules of the institute are published and available to the public. Violation of the rules may be grounds for termination as a member of the institute. Membership in the institute is a privilege and not a right. 

    Funding will provide a rosacea MAC of the best available minds on finding a cure for this disease. The selection of who is chosen to be in this MAC will be based on not only the qualifications of the individual but also from nominations by both rosacean and non rosaceans voting members of the institute.

    Sources of funding to the institute will be publicized including the name of the donor unless the donor requests anonymity. Expenses of the institute will be publicized down to the last cent, showing where all the spending went and for what purpose since transparency is a core principle of our non profit organization. 

    The philosophy and spirit of this institute is that funding should predominately be used for research and development and not for the administration of the institute. Volunteers are an integral part of this spirit and we hope to include member rosaceans and non-rosaceans who are willing to help the purpose of the institute become a reality. We need your help to find a cure for rosacea, to research rosacea, to publish the findings of this research and provide a MAC of the best available minds on rosacea. The views and suggestions of rosaceans will be an integral part in directing the research on rosacea, in choosing the MAC and the directors of the institute. Voting members of the institute will have a voice in the decision making of the institute, although directors of the institute will make all final decisions.

    Members of the institute will not profit from the institute however the Medical Advisory Committee members or members may be compensated for services rendered to the institute.

    Voting members will elect a board of directors that includes:

    Director, Assistant Director, Secretary, Treasurer and/or other board members. The board of directors will decide all matters of the institute and will be volunteers.

    Funding on rosacea research by the RRDi will not be used on animal testing.

ABSTRACT Rosacea is a chronic inflammatory disorder primarily affecting the facial skin, prominently involving the cheeks, nose, chin, forehead, and periorbital area. Cutaneous manifestations encompass persistent facial erythema, phymas, papules, pustules, telangiectasia, and flushing. The pathogenesis of rosacea is associated with various exacerbating or triggering factors, including microbial infestation, temperature fluctuations, sunlight exposure, physical exertion, emotional stress, consumption of hot beverages and spicy foods, and exposure to airborne pollen. These environmental factors interact with genetic predispositions in the development of rosacea. The roles of the lipophilic microbiome, ultraviolet radiation, nociceptive responses, and vascular alterations have been proposed as significant factors in the pathogenesis. These insights contribute to understanding the anatomical specificity of facial involvement and the progressive nature of rosacea. East Asian skin, predominantly classified as Fitzpatrick skin phototypes III to IV, is characterized by relatively diminished skin barrier function and increased sensitivity to irritants. Airborne pollen exposure may particularly act as a trigger in East Asian individuals, possibly mediated through toll-like receptors. The lack of specificity in objective clinical and histopathological findings leads to diagnostic challenges for individuals with colored skin, including East Asians, particularly when erythema is the sole objective manifestation. An alternative diagnostic scheme may thus be necessary. A diagnostic approach emphasizing vascular manifestations and nociceptive symptoms potentially holds promise for individuals with darker skin tones. More research focusing on potential variations in skin physiology across different racial groups is essential to establish more effective diagnostic schemes applicable to both dark and light skin colors.

    • Indian J Dermatol. 2024 May-Jun;69(3):232-237. doi: 10.4103/ijd.ijd_470_23. Epub 2024 Jun 26. ABSTRACT BACKGROUND: Rosacea is a chronic inflammatory skin disease. Previous studies have determined that IL-36, IL-37, and IL-38 may play a role in the pathogenesis of various inflammatory diseases. AIMS AND OBJECTIVES: The present study aims to evaluate the relationship of these cytokines with rosacea. MATERIALS AND METHODS: A total of 100 individuals, including 50 patients with rosacea and 50 healthy controls, were included in the study. IL-36, IL-37, and IL-38 levels were measured using the ELISA method by taking serum samples from all participants. RESULTS: The mean serum levels of IL-36, IL-37, and IL-38 in the patient group were 52.17 ± 24.07 pg/ml, 18.46 ± 8.18 pg/ml, and 25.74 ± 8.36 ng/l, respectively. The mean serum levels of IL-36, IL-37, and IL-38 in the control group were 32.99 ± 19.90 pg/ml, 44.61 ± 22.27 pg/ml, and 45.61 ± 17.32 ng/l, respectively. The difference between the serum levels of IL-36, IL-37, and IL-38 in the patient and control groups was statistically significant (P < 0.001). CONCLUSION: Based on these findings, an increase in IL-36 and a decrease in IL-37 and IL-38 may contribute to the pathogenesis of rosacea. Future rosacea treatments could target and/or interact with these possible steps in the pathogenesis of rosacea. PMID:39119329 | PMC:PMC11305503 | DOI:10.4103/ijd.ijd_470_23 {url} = URL to article
    • Skin Res Technol. 2024 Aug;30(8):e13875. doi: 10.1111/srt.13875. ABSTRACT BACKGROUND: Recent studies increasingly suggest that microbial infections and the immune responses they elicit play significant roles in the pathogenesis of chronic inflammatory skin diseases. This study uses Mendelian randomization (MR) and Bayesian weighted Mendelian randomization (BWMR) to explore the causal relationships between immune antibody responses and four common skin diseases: psoriasis, atopic dermatitis (AD), rosacea, and vitiligo. METHODS: We utilized summary statistics from genome-wide association studies (GWAS) for antibody responses to 13 infectious pathogens and four skin diseases. Single nucleotide polymorphisms (SNPs) were selected as instrumental variables (IVs) to assess causal relationships using multiple MR methods, including inverse variance weighted (IVW), MR Egger, and weighted median. BWMR was also employed to confirm findings and address potential pleiotropy. RESULTS: The IVW analysis identified significant associations between specific antibody responses and the skin diseases studied. Key findings include protective associations of anti-Epstein-Barr virus (EBV) IgG seropositivity and Helicobacter pylori UREA antibody levels with psoriasis and AD. anti-chlamydia trachomatis IgG seropositivity, anti-polyomavirus 2 IgG seropositivity, and varicella zoster virus glycoprotein E and I antibody levels were negatively associated with rosacea, while EBV Elevated levels of the early antigen (EA-D) antibody levels and HHV-6 IE1B antibody levels were positively associated with rosacea. H. pylori Catalase antibody levels were protectively associated with vitiligo, whereas anti-herpes simplex virus 2 (HSV-2) IgG seropositivity was positively associated with vitiligo. The BWMR analysis confirmed these associations. CONCLUSION: This study underscores the significant role of H. pylori and other pathogens in these skin diseases, suggesting both protective and exacerbating effects depending on the specific condition. Understanding these pathogen-immune interactions can lead to the development of more effective, personalized treatments and preventative strategies, ultimately improving patient outcomes and quality of life.

ABSTRACT Numerous recent evidence highlights epidemiological connections between rosacea and metabolic disorders. However, the precise path through which metabolic factors impact rosacea risk is still unclear. Therefore, this study aims to investigate the role of adiponectin, a crucial adipokine that regulates metabolic homeostasis, in the pathogenesis of rosacea. We elucidated a detrimental feedback loop between rosacea-like skin inflammation and decreased levels of skin adiponectin. To elaborate, rosacea lesional skin exhibits diminished adiponectin expression compared to non-lesional areas in the same patients. Induction of rosacea-like inflammation reduced adiponectin levels in the skin by generating inflammatory cytokines that suppress adiponectin production from subcutaneous adipocytes. Conversely, complete depletion of adiponectin exacerbated rosacea-like features in the mouse model. Mechanistically, adiponectin deficiency led to heightened S6 phosphorylation, a marker of the mTORC1 signaling pathway, in the epidermis. Adiponectin significantly inhibited S6 phosphorylation in cultured keratinocytes. Notably, replenishing adiponectin whole protein or topically applying an agonist for adiponectin receptor 1 successfully improved rosacea-like features in mice. This study contributes to understanding the role of adiponectin in skin inflammation associated with rosacea pathophysiology, suggesting that restoring adiponectin function in the skin could be a potential therapeutic strategy.

    • Cutan Ocul Toxicol. 2024 Aug 8:1-5. doi: 10.1080/15569527.2024.2383242. Online ahead of print. ABSTRACT BACKGROUND/ OBJECTIVES: Rosacea is a common chronic inflammatory skin disorder. Endocrinedisrupting chemicals (EDC) are toxic substances, that may gain entry through the skin and subsequently interfere with hormonal and immune functions. Bisphenol A (BPA) and pentachlorophenol sodium (PCS) are two of these EDCs, incriminated in the pathogenesis of certain inflammatory skin disorders. We aimed to test the hypothesis that exposure to BPA and PCS might be involved in the pathogenesis of rosacea. METHODS: This prospective cross-sectional study involved 34 patients with rosacea (18F/16 M; mean age 48.5 ± 11 years) and 34 age and sex-matched healthy controls (20 F/14 M; mean age 48.2 ± 10.2 years). Main anthropometric measures, fasting plasma glucose (FPG), insulin, HOMA-IR, lipids, C-reactive protein (CRP), BPA, and PCS levels were quantified and recorded. RESULTS: Serum CRP (9.6 ± 3.4 vs. 3.7 ± 1.6 mg/L, respectively, p0.05 for all). Serum BPA levels were 55.8 ± 14.4 and 51.9 ± 19.2 ng/mL, and PCS levels were 63.3 ± 45.9 ng/mL and 68.6 ± 40.8 ng/mL for patients and healthy controls, respectively. There was no significant difference in BPA and PCS levels between the two groups (p > 0.05 for both). No significant association was found among HOMAIR, CRP, BPA, and PCS levels (p > 0.05 for all). CONCLUSIONS: Although the present study fails to provide presumptive evidence for the role of BPA and PCS in rosacea, the question as to other EDCs might be involved in its etiopathogenesis remains. This hypothesis requires confirmation in large-scale future prospective trials. PMID:39113570 | DOI:10.1080/15569527.2024.2383242 {url} = URL to article
