    In January 2005 the Board of Directors chose me as the director of the RRDi, and Warren Stuart as the Assistant Director. In 2010 we were again voted to serve another five years on the board. Same for 2015 and in 2020. The board decided to make me the treasurer in 2020 and Apurva Tathe as the director. 

    Warren was instrumental in forming and establishing the RRDi, helping out with our web site and setting up our member forum. Warren also established a sister site relationship with his Rosacea Forum. Sadly, Warren passed away in 2012 (for more info click here).

    You might be interested in a more detailed history of the RRDi

    An article was written on why I formed the RRDi. You should carefully investigate the other non profit organizations for rosacea and compare how they are run with the RRDi. The big difference is that this non profit is run with a volunteer spirit by rosacea sufferers, a grassroots, patient advocacy effort. The other non profit organizations for rosacea are run by non rosaceans who are businessmen and dermatologists. 


    Volunteers
    This is the driving force behind this non profit organization for rosacea founded by rosacea sufferers. For more information

    Spending
    The one thing you can be sure of is that any donations will NOT be spent on private contractors or salaries at this point since everyone associated with the RRDi are volunteers. This can be done because of the volunteer spirit with which this institute was set up. Can you help? When you join, in the comment box let us know you want to volunteer. If you simply join that would increase our numbers. Any small donation helps us keep going. However, volunteering is what makes this non profit different from the other rosacea non profits (read this post). 

    Research
    A database of research suggestions is being accumulated which you may access or make suggestions by clicking here.

    Who Serves on the Board of Directors
    The RRDi is the only non profit that allows rosaceans any say in determining who is on the board of directors. The other non profits are closed board of directors and if you aren't happy with the direction there is nothing you can do about it. Whatever the direction the RRDi takes, whether to research the cause, or the cure, or whatever is done you can at least know that rosaceans had a say into what research the RRDi will engage in. While the board of directors have the final say on this, you can change who serves on the board of directors who are all rosacea sufferers. Try doing this with the other non profit organizations for rosacea. 

    Transparency
    We believe in transparency. How the RRDi is run is public knowledge. You can clearly review all our financial records. All the other non profits keep their articles of incorporation a deep secret. Their financial records are cryptically revealed in only an IRS Form 990 report that is confusing and difficult to read. That is a big difference. You have a say if you join and become a corporate member. You can vote who is on the board of directors. Can you do that with any other rosacea non profit organization? I have always felt that rosaceans should have a say in what is being done and not leave that up totally to those who may have their own agenda or leave the decision to private contractors. The MAC at the RRDi is just that; a medical ADVISORY committee. The board of directors who are rosaceans make the final decision on the research and all matters. And if you desire, you as a rosacean, if you join the RRDi as a corporate member, can determine who serves on the board of directors.

    Non Profit Organization
    501 (c) (3) tax-exempt status has been approved by the IRS effective June 7, 2004. This means your donation is tax deductible. With such a legacy, you can see the RRDi is a solid non profit organization for rosaceans you can trust. Please join

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
