    • Skin Appendage Disord. 2022 Nov;8(6):462-468. doi: 10.1159/000525024. Epub 2022 Jun 7. ABSTRACT INTRODUCTION: The present study aimed to obtain fundamental data, including climate conditions and Demodex mites, on rosacea and similar diseases in the situation where the wearing of face masks is mandatory due to the coronavirus disease 2019 pandemic. METHODS: We enrolled 86 Japanese patients habitually wearing face masks with rosacea and similar diseases. Disease severity was assessed using the Investigator Global Assessment. The presence of Demodex mites was examined microscopically. Treatment involved acaricidal and antibiotic agents. RESULTS: The numbers of male and female patients enrolled were 11 and 75, respectively. Among these patients, 85 (98.8%), 57 (66.3%), and 76 (88.4%) had rosacea, rosacea-like dermatitis (RLD), and demodicosis, respectively. The monthly number of patients with rosacea and demodicosis showed two peaks from May to June and in October, during which monthly mean temperature was approximately 20°C (68°F). Improvement rates in rosacea, RLD, and demodicosis were significantly higher when Demodex mites were no longer detected after treatment. CONCLUSION: The present results suggest that a season with a mean temperature of approximately 20°C is a risk factor for rosacea and similar diseases in individuals wearing face masks in Japan, and a decrease in Demodex mites is associated with the attenuation of symptoms.

    • J Cosmet Laser Ther. 2022 Nov 17:1-6. doi: 10.1080/14764172.2022.2147953. Online ahead of print. ABSTRACT A chemical peel is chemexfoliation, a process of application of a chemical substance to the skin that causes controlled chemical destruction of the epidermis with or without part of the dermis leading to skin regeneration and remodeling. It can be classified depending upon the depth of penetration into superficial, medium, and deep peels. Among various indications, peels can be used to enhance treatment within a variety of conditions including skin- rejuvenation, inflammatory disorders like acne, rosacea, acne scar, and pigmentary disorders like melasma, freckles, lentigens, dyschromia, and post-inflammatory pigmentation. We did a chemical peel for six patients with facial melanosis, diagnosed with Riehl melanosis. All patients had visible clinical improvement. Detailed history and informed consent were taken both for photographs and procedures from all patients. PMID:36384385 | DOI:10.1080/14764172.2022.2147953 {url} = URL to article
    • J Clin Aesthet Dermatol. 2022 Nov;15(11):69-74. ABSTRACT OBJECTIVE: Subantibiotic dose doxycycline (SDD40), formulated as a modified-release 40mg capsule administered once daily, is used to treat inflammatory lesions of rosacea. In order to investigate whether the patient's weight or lesion severity impacts clinical outcomes with using SDD40, the efficacy and safety of SDD40 in treating rosacea were evaluated in randomized controlled studies (RCTs). METHODS: Phase II, III, and IV RCTs, and a subsequent meta-analysis were described. For all studies, the primary efficacy endpoint was the change in total inflammatory lesion count (papules, pustules, and nodules) from baseline to Week 16. For one of the studies, body weights were categorized by BMI (body mass index). Secondary efficacy endpoints included the change in Investigator's Global Assessment (IGA). Safety was assessed by monitoring adverse events (AEs). RESULTS: The efficacy of SDD40 was consistent across the studies (two trials including n=72 and n=91 subjects) and meta-analysis (n=127 and n=142). SDD40 remained effective regardless of baseline disease severity and weight (with a weak correlation coefficient below 0.75); overweight or obese subjects with severe rosacea cleared at least as well if not better than those with a normal BMI and mild disease. The treatment was well tolerated with no to minimal gastrointestinal-related AEs. LIMITATIONS: Retrospective analyses have methodological limitations. CONCLUSION: Consistency between study results including the meta-analysis supports the effectiveness and safety of SDD40, irrespective of the weight of the patient or rosacea severity based on inflammatory lesion count at baseline.

    • Transl Vis Sci Technol. 2022 Nov 1;11(11):13. doi: 10.1167/tvst.11.11.13. ABSTRACT PURPOSE: Dry eye disease (DED) is a heterogeneous condition with poorly characterized subtypes. The DREAM study was a large multicenter randomized clinical trial that did not find omega-3 to be more effective than placebo in treating symptomatic DED. We performed secondary analysis of DREAM data to characterize DED subtypes and their omega-3 response. METHODS: A total of 535 patients with moderate-to-severe DED were randomized to omega-3 or placebo treatment for one year. We used latent profile analysis to identify subtypes based on baseline Ocular Surface Disease Index, tear break-up time (TBUT), anesthetized Schirmer's test, corneal and conjunctival staining, and meibomian gland dysfunction (MGD). We evaluated omega-3's effect for each subtype using generalized linear regression. RESULTS: Five clinically meaningful DED subtypes were identified. They differed significantly in sex (P < 0.001) and race (P = 0.02). Subtype 1 had the most severe DED signs yet milder symptoms and was associated with more Sjögren's syndrome (21%, P < 0.001). Subtype 2 had the mildest DED signs except MGD. Subtype 3 had the most severe symptoms, out of proportion to DED signs. Subtype 4 had relatively milder symptoms and MGD. Subtype 5 had severe MGD and TBUT and was associated with rosacea (29%, P = 0.04). Omega-3 was not significantly more beneficial than placebo for any subtype. CONCLUSIONS: Five clinically meaningful DED subtypes differed significantly in demographics, symptoms, signs, and systemic disease associations. Omega-3 was not significantly more effective than placebo for any subtype. TRANSLATIONAL RELEVANCE: T3 translational research identifying subtypes in the DREAM study can improve DED clinical classification and targeted management.

    • J Cosmet Dermatol. 2022 Nov 14. doi: 10.1111/jocd.15492. Online ahead of print. ABSTRACT BACKGROUND: Rosacea may contribute to the development of cardiovascular (CV) diseases by causing endothelial dysfunction (ED), which is known to be the initial step of atherosclerosis, due to its inflammatory features. OBJECTIVE: This study aimed to assess ED in rosacea patients using the flow-mediated dilatation (=dilation) (FMD) method. METHODS: Seventy-three rosacea patients and 73 age, gender-matched healthy volunteers were enrolled. Individuals with cardiac risk factors, pregnant, and lactating women were excluded. Demographic, clinical data and anthropometric measurements were recorded. FMD measurement was performed ultrasonographically by a cardiologist. Systolic and diastolic blood pressures (BP) were measured and hemogram, erythrocyte sedimentation rate (ESR), C-Reactive Protein (CRP), total cholesterol, triglyceride, low-density lipoprotein (LDL), high-density lipoprotein (HDL), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), mean platelet volume (MPV), and fasting blood glucose values were assessed. RESULTS: The FMD value was statistically lower in rosacea patients compared with healthy controls (p = 0.000). Metabolic syndrome, systolic and diastolic BPs, and plasma NLR were higher in the rosacea group (p = 0.009, p = 0.000, p = 0.000, p = 0.000, respectively). According to the multivariate linear regression analysis, rosacea type significantly predicted FMD. CONCLUSIONS: Rosacea is not only a disease limited to the skin, but it may also have systemic involvement. A significant difference was found between FMD values measured in between the case and control groups, suggesting rosacea may have an atherogenic effect. Possible cardiac risks should be considered in rosacea patients, and further evaluation could be warranted. PMID:36374628 | DOI:10.1111/jocd.15492 {url} = URL to article
    • J Eur Acad Dermatol Venereol. 2022 Nov 11. doi: 10.1111/jdv.18725. Online ahead of print. ABSTRACT BACKGROUND: Rosacea is a chronic inflammatory skin disease with increased macrophage infiltration. However, the molecular mechanism remains unclear. OBJECTIVES: To determine the significance of macrophage infiltration, and correlation between Guanylate binding protein 5 (GBP5) and polarization of macrophages in rosacea-like inflammation. METHODS: Here we tested hypothesis that Guanylate binding protein 5 (GBP5) aggravate rosacea-like skin inflammation by promoting the polarization of the M1 macrophages through the NF-κB signaling pathway. We depleted macrophage by injecting clodronate-containing liposomes. We next explored the association between GBP5 and macrophage in rosacea tissue through transcriptome analysis and immunofluorescence analysis. We evaluated the severity of rosacea-like skin inflammation when BALB/c mice was injected GBP5 siRNA intradermally daily for three consecutive days. At last, to study the causality of knocking down GBP5-blunted M1 macrophages polarization, THP-1 cell was treated with GBP5 siRNA. RESULTS: Macrophage depletion ameliorated rosacea-like skin inflammation in mice, implying the important role of macrophages in the rosacea. Basing on transcriptome analysis, Guanylate binding protein 5 (GBP5) was identified as hub genes that was associated with the macrophage infiltration in rosacea. Next, we found that GBP5 expression was significantly upregulated in rosacea tissues and positively correlated with the macrophage infiltration, the immunofluorescence analysis revealed the colocalization between GBP5 and macrophages. In vivo, silencing of GBP5 attenuated rosacea-like skin inflammation in the LL-37-induced mouse model and suppressed the expression of M1 signature genes such as IL-6, iNOS, and TNF-a. In vitro, knocking down GBP5 significantly blunted the polarization of the M1 macrophages partly by repressing the activation of the NF-κB signaling pathways. CONCLUSIONS: Together, our study revealed the important role of macrophages in rosacea, and identified GBP5 as a key regulator of rosacea by inducing M1 macrophages polarization via NF-κB signaling pathways.

    • Pharmaceutics. 2022 Oct 28;14(11):2322. doi: 10.3390/pharmaceutics14112322. ABSTRACT In the present investigation, a nanoemulgel of minocycline was formulated and optimized for an improved drug delivery and longer retention time in the targeted area. Combining eucalyptus oil, Tween 20, and Transcutol HP, different o/w nanoemulsions were formulated by the oil phase titration method and optimized by pseudo-ternary phase diagrams. The morphology, droplet size, viscosity, and refractive index of the thermodynamically stable nanoemulsion were determined. Furthermore, optimized nanoemulsion was suspended in 1.0% w/v of Carbopol 940 gel to formulate the nanoemulgel, and for this, pH, viscosity, and spreadability were determined and texture analysis was performed. To compare the extent of drug penetration between nanoemulsion and nanoemulgel, ex vivo skin permeation studies were conducted with Franz diffusion cell using rat skin as the permeation membrane, and the nanoemulgel exhibited sustained-release behavior. It can be concluded that the suggested minocycline-containing naoemulgel is expected to treat acne rosacea more effectively. PMID:36365140 | DOI:10.3390/pharmaceutics14112322 {url} = URL to article
    • Front Bioeng Biotechnol. 2022 Oct 21;10:1053679. doi: 10.3389/fbioe.2022.1053679. eCollection 2022. ABSTRACT Background: Recent studies have reported that the incidence of sensitive skin is increasing. Skin sensitivity and skin barrier functions were related to many skin diseases including atopic dermatitis, psoriasis, rosacea, and so on. Mesenchymal stem cell (MSC)-derived exosomes (hMSC) might be considered as a new effective therapeutic scheme. Aims: This study aims to investigate the safety and efficacy of hMSC exosomes as a novel topical treatment for sensitive skin. Patients/Methods: Exosomes were extracted from primary hMSC via ultracentrifugation method. The morphology of hMSC exosomes was studied via transmission electron microscope. Expression of exosome specific surface marker was detected via Western blot. 22 subjects (female, aged 18-55) diagnosed with sensitive skin were enrolled. Follow-up was conducted before, 7-day, 14-day, and 28-day after hMSC exosomes use. Transepidermal water loss (TEWL), surface hydration, sebum secretion, and L*a*b* value were simultaneously tested at the same time point in an environment-controlled room. Results: Under transmission electron microscopy, the extracted hMSC exosomes were circular or elliptical with intact membrane structure, and their diameters ranged mainly from 40 to 80 nm. Western blot showed that the expression of markers CD63, CD9, and Tsg101 was positive. Brownian motion based nanoparticle trajectory analysis (NTA) showed that the main peak of particle size distribution occurred around 96 nm, the average particle size was 122 nm, and the main peak accounted for 96.7%. All this conformed to the biological characteristics of exosomes standardized by the International Society for Extracellular Vesicles. In the clinical trial, scores of objective symptoms including roughness, scales, erythema, and subjective symptoms including tension, burning, or itching, were improved after 7-, 14-, and 28- day using hMSC-exosomes. TEWL, hydration, sebum, pH, and a* values were tended to return to the level of healthy skin. Conclusion: The hMSC-exosomes, with the advantages of biocompatibility and biodegradability, could improve clinical symptoms and eruptions in sensitive skin patients, and might be as an MSC cell-free novel therapy in sensitive skin-related disease treatment.

ABSTRACT BACKGROUND: An overlap between the skin disease rosacea and the headache disease migraine has been established; however, the magnitude of this overlap and the distribution between subtypes/phenotypes remains unclear. OBJECTIVE: The aim was to determine the magnitude of the overlap between rosacea and migraine, and to determine which subtypes/phenotypes were present in patients with concomitant rosacea and migraine. METHODS: In this cross-sectional study, 604 patients with a diagnosis of either rosacea or migraine were phenotyped through a face-to-face interview with clinical examination, to determine prevalence and phenotype of rosacea, and prevalence and subtype of migraine. RESULTS: We found a prevalence of migraine of 54% in patients with rosacea, and a prevalence of rosacea of 65% in patients with migraine. Concomitant migraine was significantly associated with the rosacea features flushing (odds ratio = 2.6, 95% confidence interval = 1.4-4.7, p = 0.002), ocular symptoms (odds ratio = 2.4, 95% confidence interval = 1.5-3.9, p < 0.001), and burning (odds ratio = 2.1, 95% confidence interval = 1.3-3.4, p = 0.002), whereas papules/pustules were inversely related with concomitant migraine (odds ratio = 0.5, 95% confidence interval = 0.3-0.8, p = 0.006). No association was found between concomitant migraine and centrofacial erythema, rhinophyma, telangiectasia, edema, or dryness. Concomitant rosacea was not associated with any specific migraine subtype in patients with migraine. CONCLUSION: This study highlights a substantial overlap between rosacea and migraine, particularly in patients with certain rosacea features. Individuals with rosacea should be asked about concomitant migraine, and comorbidities should be considered when choosing between treatments.

    • Inflamm Res. 2022 Nov 3. doi: 10.1007/s00011-022-01635-6. Online ahead of print. ABSTRACT BACKGROUND: Rosacea, a chronic inflammatory disorder of the facial skin, is effectively treated by intense pulsed light (IPL). OBJECTIVE: To explore the potential molecular mechanism underlying the photobiomodulation effect of IPL for rosacea treatment. METHODS: Skin samples from patients with rosacea were subjected to histological and immunohistological staining. Ten patients were followed up after IPL treatment using the VISIA® skin analysis system, and the severity was assessed. In vivo, skin changes in mice with rosacea-like inflammation induced by intradermal injection of 320 μM LL-37 with or without IPL treatment were evaluated using L*a*b colorimetry as well as histological and immunological staining. In vitro, LL-37-stimulated mast cells (MCs) with or without IPL treatment were evaluated for protein expression of matrix metalloproteinase (MMP)-9, kallikrein-related peptidase 5 (KLK5), and cathelicidin using western blotting and qRT-PCR. RESULTS: Profound infiltration of inflammatory cells and evident MC degranulation were found in rosacea skin lesions. The expression of rosacea-related biomarkers and inflammatory cytokines was higher in lesional areas than in non-lesional areas, as demonstrated via immunochemical staining. In all patients, rosacea severity reduced after IPL therapy. In vivo, IPL alleviated inflammation in mice with rosacea-like inflammation, as demonstrated by the significantly decreased MMP-9, KLK5, and cathelicidin expression and reduced percentage of degranulating MCs. In vitro, IPL decreased MMP-9, KLK5, and cathelicidin expression in P815 cells, reducing the release of inflammatory cytokines and inhibiting rosacea-like inflammatory reactions. CONCLUSION: The photobiomodulation effect of IPL for rosacea treatment may inhibit MC degranulation and alleviate inflammatory reactions.

    • Expert Opin Pharmacother. 2022 Nov 5:1-10. doi: 10.1080/14656566.2022.2142907. Online ahead of print. ABSTRACT INTRODUCTION: Rosacea is a chronic and relapsing facial dermatosis that encompasses a wide spectrum of clinical phenotypes (transient/persistent erythema, telangiectasias, papules/pustules, edema, phymatous changes, and ocular symptoms) often with uncomfortable symptoms such as flushing, pain, burning, edema, and dryness. Current pharmacological treatment includes topical agents, spanning from several conventional (azelaic acid, metronidazole, sodium sulfacetamide) to new ones (brimonidine, oxymetazoline, ivermectine, minocycline), and systemic agents (doxycycline 40 mg modified-release), all Food and Drug Administration approved. AREAS COVERED: The aim of our article is to review the state of art of pharmacological treatment, either as monotherapy or in combination therapy, tailored to the most common rosacea phenotypes (persistent erythema, inflammatory papules/pustules). Other off-label topical or systemic drugs and several adjuvant phytotherapeutic agents are considered. EXPERT OPINION: Combined therapies to target different phenotypes, when present in the same patient, represent one of the major achievements in the management of vascular and inflammatory papules and pustules of rosacea. Future investigations should be addressed to early inflammatory phyma or ocular rosacea, which have actually been neglected. Finally, there is still an ongoing need for therapeutic interventions able to relieve symptoms and social burden, all factors that greatly contribute to improve rosacea quality of life.

    • J Eur Acad Dermatol Venereol. 2022 Nov 4. doi: 10.1111/jdv.18721. Online ahead of print. ABSTRACT BACKGROUND: Rosacea is a common chronic inflammatory facial skin disorder. Standardized evaluation of the severity and extent of rosacea is important for baseline assessment and treatment effect. The currently used Investigator's Global Assessment (IGA) is unspecific and fails to consider subtypes/phenotypes of rosacea and area involvement. The Rosacea Area and Severity Index (RASI) was developed to give a more nuanced evaluation of rosacea features in four facial skin areas adjusted to the relative importance of each area of the face to obtain an overall severity score. OBJECTIVES: To validate RASI against the IGA and to assess the inter- and intraobserver reliability for RASI. METHODS: Sixteen dermatologists evaluated photos of 60 adult patients with rosacea (3 photos pr patient, one from the front and one from each side). IGA and RASI scores were performed for interobserver reliability assessment. To determine intraobserver reliability, 14 dermatologists evaluated 10 other patients twice with at least one week interval. RESULTS: The IGA and RASI correlated well (Spearman Correlation Coefficient (SCC) = 0.75, 95% confidence interval (CI) = 0.72 - 0.78). Interobserver reliability was moderate for RASI and poor to moderate for IGA. Reliability was strongest for rhinophyma, followed by papules/pustules and erythema, and rather weak for telangiectasia. For area scores, interobserver reliability was strongest for cheeks, followed by nose, chin and forehead. We found a moderate-to-strong intraobserver agreement both for IGA and RASI. CONCLUSIONS: We have designed a new practical tool to examine clinical severity of rosacea. RASI proved simple and reliable in scoring clinical severity of rosacea with an agreement comparable to the currently used IGA although RASI will provide a more nuanced view of the current rosacea extent and severity. We suggest that RASI is used in the daily clinical setting as well as in clinical studies assessing the efficacy of rosacea therapies. PMID:36331365 | DOI:10.1111/jdv.18721 {url} = URL to article

ABSTRACT BACKGROUND: Ocular rosacea is a chronic inflammatory disorder with periods of exacerbation and remission, often underdiagnosed in children. When diagnosed, its management is challenging because of a lack of effective long-term treatment options. OBJECTIVE: To report our experience in cases of pediatric ocular rosacea treated with moist heat therapy and topical azithromycin 1.5%. METHODS: The medical records of six children diagnosed with ocular rosacea based on a careful medical history and slit-lamp examination of the eyelids and ocular surface were reviewed. Previous treatments were discontinued, and children/parents were instructed to use the eyelid-warming device for 1 or 2 sessions of 10minutes each day, followed by eyelid massage and cleansing, in combination with azithromycin 1.5% eye drops. RESULTS: The diagnosis of ocular rosacea in these children was delayed for several months or years from the first identifiable clinical sign or symptom. All the children presented with corneal sequelae and decreased vision. Ocular manifestations included meibomian gland disease, recurrent chalazia, and phlyctenular keratoconjunctivitis. Cutaneous signs were not always associated with the condition. Ocular rosacea was usually resistant to initial treatments with antibiotics and topical corticosteroids. Treatment with the eyelid-warming device in combination with azithromycin 1.5% led to a rapid improvement in the clinical signs and was well tolerated by all patients. CONCLUSIONS: Childhood ocular rosacea is potentially sight threatening. Practitioners should consider this condition in order to minimise diagnostic delay and subsequent complications. Combined therapy of eyelid hygiene (including an eyelid warming device) and azithromycin 1.5% eye drops was effective in treating ocular rosacea in children.

    • Dermatology. 2022 Oct 28:1-20. doi: 10.1159/000526296. Online ahead of print. ABSTRACT BACKGROUND: Demodex mites are related to some inflammatory diseases such as rosacea and blepharitis and could be harmful in patients with immunodeficiency or immunosuppression, especially notable in patients using biologic like dupilumab. In order to have an objective observation of different anti-Demodex strategies, we conducted this study, based on interventional clinical evidence with quantified Demodex mite data. METHODS: We used the PubMed, Embase, ClinicalTrials.gov, Medline, and International Clinical Trials Registry Platform (ICTRP) as databases. To assess the risk of bias, the RoB2 and ROBINS-I tools were used. The certainty of evidence was assessed following the GRADE guideline. Furthermore, the effect sizes (ESs) of different strategies were compared in different time periods (0-1, 1-2, 2-3, >3 months), as well as Demodex decrease rates. RESULTS: 1,618 studies were identified in the databases, with 21 of which included in the final quantitative synthesis. Interventions in these studies included ivermectin, tea tree oil (TTO), permethrin, crotamiton, metronidazole, light therapies, combined therapies, and other therapies. During 0-1 month, the ES varied from 0.07 (cleanser) to 1.95 (systemic ivermectin-metronidazole). During 1-2 months, the ES varied from 0.88 (topical permethrin) to 4.40 (topical ivermectin). During 2-3 months, the ES varied from 0.79 (topical permethrin) to 8.37 (topical ivermectin). During the time of 3 months, the ES varied from 0.59 (topical permethrin) to 2.25 (intense pulsed light [IPL]). In terms of Demodex decrease rates, topical ivermectin, TTO, permethrin, IPL, and baby shampoo had achieved a nearly 100% decrease. The reported adverse events were mostly mild, without severe adverse events reported in any of the studies. CONCLUSIONS: We found ivermectin (topical and systemic), ivermectin-metronidazole (topical), and TTO (topical) are promising anti-Demodex interventions. In addition to traditional pharmacotherapy, light therapies, especially IPL and skin cleansing, could also be considered as effective methods to control Demodex mite infestation.

ABSTRACT Isolated pigmentation of the nails induced by minocycline therapy is an uncommon occurrence that has only been reported in a handful of cases. In the reported cases of isolated nail discoloration, it has been suggested that nail discoloration may occur preceding other sites of pigmentary changes. As certain types of minocycline-induced pigmentation can be permanent, it is important for clinicians to be aware of this association and discontinue therapy as soon as pigmentary changes are noticed. In this report, we present a case of isolated nail discoloration in the setting of prolonged minocycline therapy for the treatment of rosacea.

    • Biomedicines. 2022 Oct 9;10(10):2523. doi: 10.3390/biomedicines10102523. ABSTRACT The skin harbors a huge number of different microorganisms such as bacteria, fungi and viruses, and it acts as a protective shield to prevent the invasion of pathogens and to maintain the health of the commensal microbiota. Several studies, in fact, have shown the importance of the skin microbiota for healthy skin. However, this balance can be altered by intrinsic and extrinsic factors, leading to the development of skin disease, such as acne vulgaris (AV), atopic dermatitis (AD) and rosacea(RS). Although these diseases are widespread and affect both adolescents and adults, the scientific correlation between these disorders and the skin microbiota and physiological parameters (TEWL, hydration and lipid composition) is still unclear. This review aims to investigate the current literature regarding the correlation between the skin microbiota and its imbalance underlying microbiological aspects, how the skin microbiota changes over the course of the disease and the current possible treatments. The following reported studies show a general imbalance of the bacterial flora. For this reason, more in-depth studies are necessary to explore the different subspecies and strains involved in all three diseases.

    • Eur J Dermatol. 2022 Jul 1;32(4):505-515. doi: 10.1684/ejd.2022.4301. ABSTRACT BACKGROUND: Ocular rosacea is a common skin condition leading to dry eye that is difficult to manage. OBJECTIVES: To estimate the efficacy and safety of a new intense pulsed light device, Thermaeye Plus, for meibomian gland dysfunction and blepharitis due to ocular rosacea. MATERIALS & METHODS: This prospective, longitudinal study included 74 eyes of 37 consecutive patients with ocular rosacea, with mean age of 45.6±11.7 years. Four consecutive sessions were undertaken, including14 flashes with 10 J/cm² on the periocular area and facial cheeks on Day 1, 14, 28, and 49. Clinical evaluation was based on: ocular surface disease index (OSDI) and symptom score questionnaires, quality of live and facial severity degree, non-invasive tear meniscus height, non-invasive tear break up time, corneal fluorescein staining and eyelid margin and meibomian gland assessment. Adverse effects on the eye and periocular area, and systemic complications were evaluated. RESULTS: The OSDI questionnaire showed a decrease in symptoms, achieving normal values in 91.9% of patients. The symptom score showed amelioration, with the most significant changes relating to dryness, foreign body sensation, light sensitivity, and pain. Longitudinal analysis showed the most significant improvement between baseline at Day 1 and 49. All eyelid signs improved, most significantly for telangiectasia/vascularity and blepharitis, leading to a 78% clearance of facial rosacea and 81.1% reduction of flushing. In total, 100% of the patients reported an improvement in their quality of life after treatment and 94.6% a very significant improvement (p<0.001). CONCLUSION: These results demonstrate that Thermaeye Plus is an effective and safe treatment for ocular rosacea. PMID:36301756 | DOI:10.1684/ejd.2022.4301 {url} = URL to article
    • JAMA Dermatol. 2022 Oct 26. doi: 10.1001/jamadermatol.2022.3911. Online ahead of print. ABSTRACT IMPORTANCE: Acne and rosacea have substantial implications for quality of life, and it is therefore important to ensure the patient's voice is being captured in pivotal randomized clinical trials (RCTs). Although patient-reported outcome measures (PROMs) are a valuable tool to capture the patient perspective, little is known about use of PROMs in RCTs on acne and rosacea. OBJECTIVE: To characterize the use of PROMs in RCTs on acne and rosacea. EVIDENCE REVIEW: A systematic literature search was conducted using the search terms acne vulgaris and rosacea in the following databases: MEDLINE through PubMed, Embase, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews. A modified search hedge for RCTs from the McGill Library was applied. All phase 2, 3, and 4 RCTs published between December 31, 2011, through December 31, 2021, that evaluated the efficacy and safety of therapies for acne and rosacea vs any comparator were eligible for inclusion. FINDINGS: A total of 2461 publications describing RCTs were identified, of which 206 RCTs met the inclusion criteria (163 trials [79%] on acne and 43 [21%] on rosacea). At least 1 PROM was used in 53% of trials (110) included; PROM use was more common in rosacea RCTs (67% [n = 29]) compared with acne RCTs (50% [n = 81]). At least 1 dermatology-specific (13% [n = 27]) or disease-specific (14% [n = 28]) PROM was included in the RCTs analyzed. Only 7% of trials (14) included a PROM as a primary outcome measure. There was no statistically significant increase in PROM inclusion over the study period (11 of 21 trials in 2011 vs 5 of 12 trials in 2021). CONCLUSIONS AND RELEVANCE: In this systematic review, PROMs were included in approximately one-half of acne and rosacea RCTs performed over the study period. In addition, PROMs were rarely used as a primary outcome measure, and inclusion of PROMs has not increased substantially over the past 10 years. Increasing use of PROMs in RCTs can ensure that the patient's perspective is captured during the development of new treatments for acne and rosacea.

ABSTRACT BACKGROUND: Rosacea is a common and complex chronic inflammatory skin disorder, the pathophysiology and etiology of which remain unclear. Recently, significant new insights into rosacea pathogenesis have enriched and reshaped our understanding of the disorder. A systematic analysis based on current studies will facilitate further research on rosacea pathogenesis. OBJECTIVE: To establish an international core outcome and knowledge system of rosacea pathogenesis and develop a challenge, trend and hot spot analysis set for research and clinical studies on rosacea using bibliometric analysis and data mining. METHODS: A search of the WoS, and PubMed, MEDLINE, Embase and Cochrane collaboration databases was conducted to perform visual bibliometric and data analysis. RESULTS: A total of 2,654 studies were used for the visualization and 302 of the 6,769 outcomes for data analysis. It reveals an increased trend line in the field of rosacea, in which its fast-growing pathogenesis attracted attention closely related to risk, comorbidity and therapeutic strategies. The rosacea pathogenesis has undergone the great development on immunology, microorganisms, genes, skin barriers and neurogenetics. The major of studies have focused on immune and microorganisms. And keyword visualization and data analyses demonstrated the cross-talk between cells or each aspect of pathogenesis, such as gene-gene or gene-environment interactions, and neurological mechanisms associated with the rosacea phenotype warrant further research. LIMITATIONS: Inherent limitations of bibliometrics; and reliance on research and retrospective studies. CONCLUSIONS: The understanding of rosacea's pathogenesis has been significantly enhanced with the improved technology and multidisciplinary integration, but high-quality, strong evidence in favor of genomic and neurogenic requires further research combined with a better understanding of risks and comorbidities to guide clinical practice.

ABSTRACT Metronidazole (MNZ) is a nitroimidazole derivative antibiotic that has been generally used in the treatment of rosacea. However, it has low molecular weight and lipophilicity, limiting the effectiveness of MNZ in the topical treatment of rosacea. This study reports an MNZ-loaded solid lipid microparticle (SLM) gel formulation with sustained drug release effects required in the treatment of rosacea. SLM was formulated using the double emulsification method with five different concentrations of glyceryl monostearate (GMS) as a solid lipid used to encapsulate MNZ. All the MNZ-loaded SLM formulas were extensively characterized by various analytical tools. After optimized MNZ-loaded SLM formulation was obtained, then formulated into gel preparation. To obtain a gel formula with good physical characteristics and drug release in the development of topical therapy, the SLM-loaded gel was further evaluated, covering various parameters such as pH, viscosity, rheology, spreadability, extrudability, skin occlusivity, gel strength, permeation and retention ex vivo, as well as hemolysis tests and antioxidant activity. The evaluation results showed that the SLM formulations had desired properties with optimum encapsulation efficiency. Moreover, the gels prepared from carbomer possessed desired characteristics and were found to be hemocompatible. In addition, the gel formula with a carbomer concentration of 1.25% can provide better drug release with the highest MNZ retention after 24 hours of 2.35 ± 0.05 mg. Notably, the formulation of MNZ into SLM and hydrogel did not affect the antioxidant activity. Thus, it can provide continuous drug release, which could potentially be useful in increasing efficacy in rosacea therapy. The results obtained also showed a significant difference (p < 0.05) compared to the control formula and other formulas. Therefore, this study has proven a new approach to developing drug delivery systems for rosacea treatment. PMID:36280218 | DOI:10.1016/j.ijpharm.2022.122327 {url} = URL to article
    • image courtesy of the TEA non profit organization Erythromelagia (EM) is one possible diagnosis to differentiate from rosacea. What is it? According to the TEA web site: "Erythromelalgia is a rare and frequently devastating disorder that typically affects the skin of the feet or hands, or both, and causes visible redness, intense heat and burning pain. The term erythromelalgia describes the syndrome: erythros (redness), melos (extremity) and algia (pain). An alternate name is “erythermalgia” that emphasizes the thermos (heat) – an essential part of the syndrome. While usually affecting the lower extremities (legs and feet) and upper extremities (arms and hands) other body parts like faces or just ears or the nose may be involved. It usually affects both sides of the body, but can affect just one. The associated pain and burning sensations can be extremely severe. People with EM often make major adjustments to their lifestyles to avoid flare-ups. Even in mild-to-moderate cases, normal functioning such as walking, standing, working, socializing, exercising, and sleeping may be impaired." What is EM? "In 2004 erythromelalgia became the first human disorder in which it has been possible to associate an ion channel mutation with chronic neuropathic pain, when its link to the SCN9A gene was initially published in the Journal of Medical Genetics." Wikipedia EM can involve the face.[5] Diagnosis "Experts indicate that the intermittent nature of erythromelalgia in some cases may potentially lead to difficulties or delays in its diagnosis. Therefore, because symptoms may be reduced or absent until late in the day, for example, physicians may recommend that affected individuals take pictures of the involved regions during flaring and/or schedule clinical examinations late in the day if possible. In addition, during diagnostic assessment, physicians may possibly recommend exercise or immersion of an affected region in hot water for a certain period (e.g., approximately 10 to 30 minutes), to provoke a flare so a diagnosis may be made." [7] Treatmentt "In this informal survey, the use of high oral doses of magnesium produced good and sometimes dramatic results in 8 of 13 patients who had been unresponsive to many other treatments. These results suggest a possible role for high-dose oral magnesium in the treatment of EM and, perhaps, other vascular disorders." [1] "We tried oral mexiletine, a class Ib antiarrythmic agent, in view of its reported role in various chronic painful conditions. Dramatic improvement was observed with its use. Both patients improved after several weeks of use, and there were fewer soaking episodes. We observed no adverse effects with mexilitine therapy." [2] "Lumbar sympathetic block and TSB are useful methods for treatment of primary erythromelalgia." [3] "We conclude that thalamic stimulation was successful in this case of primary erythromelalgia." [4] Ketamine 0.5% and Amitriptyline 1% has been used as a treatment not only for EM but also for rosacea.  "Even when the correct diagnosis of erythromelalgiais made, treatment is difficult, with no single therapy consistently effective." [5] "One clinical study has demonstrated the efficacy of IV lidocaine or oral mexilitine, though differences between the primary and secondary forms were not studied. Another trial has shown promise for misoprostol, while other have shown that gabapentin, venlafaxine and oral magnesium may also be effective, but no further testing was carried out as newer research superseded this combination. Strong anecdotal evidence from EM patients shows that a combination of drugs such as duloxetine and pregabalin is an effective way of reducing the stabbing pains and burning sensation symptoms of erythromelalgia in conjunction with the appropriate analgesia. In some cases, antihistamines may give some relief. Most people with erythromelalgia never go into remission and the symptoms are ever present at some level, whilst others get worse, or the EM is eventually a symptom of another disease such as systemic scleroderma."

If only the members of the RRDi would follow the example of TEA. We can only hope our members see the need to volunteer and make donations for rosacea as TEA members have done.

    • First off, if you don't know what Erythromelalgia is, it is listed as a rosacea mimic and should be ruled out in a differential diagnosis of rosacea.  Someone kindly pointed out to me that The Erythromelalgia Association website is very user friendly and was impressed with the free Guide it offers on its website indicating to me that the RRDi needs to be more 'user friendly' and offering such a guide. So I decided to investigate and contacted TEA and asked for a copy of the latest Form 990 which was emailed to me and I have given a cursory investigation and am very impressed with how this 501 c 3 non profit organization spends its donations.  Form 990 First off, the board of directors are all volunteers. TEA has 2000 members, is a grassroots patient advocacy 501 c 3 non profit organization, and more importantly in 2018 received over $50K in donations which were 100% public (no private donations).  They spent $103K which breaks down to this:  $75,000 for Grants and similar amounts paid (list in Schedule O) "Gift for research directly related to erythromelalgia" $13,398 for Professional fees and other payments to independent contractors $14,230 for Printing, publications, postage, and shipping (newsletter) $884 for other expenses Total Expenses $103,512 Download Form 990 EZ for 2018 and read it yourself: Form990Package.2018.pdf The RRDi Imitates the TEA So the TEA is definitely how a non profit organization should be run and I give the highest marks (4 stars) possible to TEA for how it is helping Erythromelalgia sufferers. We wish that the members of the RRDi would be interested in imitating the TEA and help make the RRDi just like how TEA is run. The RRDi is very similar in how the board of directors are volunteers. We just need volunteers to step up to plate like the TEA volunteers are doing. It would be good for members of the RRDi to ask questions about the above or comment on this post. Just like the RRDi whose board of directors all suffer from rosacea, TEA's board of directors have at least five who suffer from EM. In 2018 these volunteers donated $50K for EM research, and actually spent $75K on 'research directly related to erythromelalgia.' Isn't that the way a non profit organization should work? Compare that with the three other non profits for rosacea who spend most of the donations on private contractors owned by one of the board of directors or spend most of the donations on the members who are mostly dermatologists for meetings and conventions, and very little, around ten percent on rosacea research. The three other non profit organizations for rosacea are run by business professionals or dermatologists and not one of the board members suffer from rosacea which explains why and how these three other non profit organizations for rosacea spend the donations. Will rosaceans ever be united and support a non profit organization like TEA? Hope.
    • Acta Derm Venereol. 2022 Oct 17. doi: 10.2340/actadv.v102.2563. Online ahead of print. ABSTRACT The association between rosacea and skin cancer remains inconclusive, with conflicting reports. The aim of this nationwide population-based cohort study was to determine the risk of skin cancer in patients with rosacea. A rosacea cohort (n = 11,420) was formulated and evaluated from 2010 to 2019. The incidence rate ratios of actinic keratosis, cutaneous melanoma, keratinocyte carcinoma and gastric, colorectal, and liver cancer were analysed in comparison with a matched control group, and multivariable stratified Cox proportional hazards model analysis was performed. The risk of actinic keratosis and keratinocyte carcinoma was increased in the rosacea group compared with the control group, with adjusted hazard ratios of 6.05 (95% confidence interval 3.63-10.09) and 2.66 (1.53-4.61), respectively. The risk of cutaneous melanoma and gastric, colorectal and liver cancer was not increased, with adjusted hazard ratios of 1.69 (0.25-11.37), 0.81 (0.59-1.10), 0.91 (0.69-1.18) and 1.32 (0.89-1.95), respectively. These results reveal an increased risk of actinic keratosis and keratinocyte carcinoma in patients with rosacea. PMID:36250731 | DOI:10.2340/actadv.v102.2563 {url} = URL to article
    • J Cosmet Dermatol. 2022 Oct 13. doi: 10.1111/jocd.15467. Online ahead of print. ABSTRACT BACKGROUND: Facial persistent erythema is recognized as difficult feature to treat in rosacea. Topical Oxymetazoline cream 1% has been used to treat persistent facial erythema in rosacea patients for some years. OBJECTIVE: To quantitatively synthesize the benefits and harms of Oxymetazoline cream 1% in real-world clinical management of treatment response and adverse events. METHODS: The clinical researches before june1st ,2022 published on online databases including PubMed, Web of Science, Embase and Cochrane Library were meta-analyzed. RESULTS: A total of 2298 participants were included, and the improvement rate of two-grade Clinician Erythema Assessment score (CEA) and Subject Self-Assessment for rosacea facial redness score (SSA) in Oxymetazoline group was 38% (95%CI 28-48) and 25% (95%CI 22-27), respectively at the 4th week of the dosing. The comprehensive rate of treatment-related TEAEs in Oxymetazoline group was 7% (95%CI 5-8). The rate of stinging/burning was 15% (95%CI 10-19), pruritus was 15% (95%CI 9-22), dryness was 23% (95%CI 18-28), and scaling was 17% (95%CI 12-22) in analysis of dermal tolerability. And topical Oxymetazoline cream 1.0% presented a very low rebound rate of erythema (1%, 95%CI 0-2). CONCLUSIONS: These real-world data on Oxymetazoline cream 1% in rosacea associated erythema may help making clinic decision and informing treatment expectations, and more clinic trials on longer-term dosing or the combination treatment with oral medication and energy-based therapy are worth exploring.

    • J Cosmet Dermatol. 2022 Oct 13. doi: 10.1111/jocd.15470. Online ahead of print. ABSTRACT BACKGROUND: Aging remains a common influencing factor for many diseases. Previous studies have shown that age is significantly associated with rosacea among female cases and that the incidence of rosacea increases with age. However, previous studies did not specifically analyze the clinical characteristics of different age groups. OBJECTIVE: This study aimed to analyze and compare the clinical characteristics of female patients of rosacea among different age groups. METHODS: We conducted a retrospective study of 840 female rosacea subjects and compared cutaneous features, aggravating factors, systemic diseases, and psychological states across age groups. The patients were divided into three groups according to their age at diagnosis:≤ 30years,31-44 years,≥45 years. RESULTS: In our study, the mean age of subjects was 35.9±10.23 years. The common symptoms included telangiectasia(82.6%), persistent erythema(82.0%), burning/stinging sensation(89.3%), dry sensation(74.0%) and pruritis(41.9%). Hot temperature(89.9%),emotional changes(67.3%), spicy food(55.6%) and sun exposure(50.7%) were the common aggravating factors. Some patients had comorbidities of systemic disorders (20.4%). 48.8% of patients presented with anxiety and 35.2% with depression. The clinical characteristics were found to be significantly different among the different age groups. Middle-aged and older patients (≥45 years)were more likely to have more serious persistent erythema, telangiectasia. And these patients were relatively less affected by some of the influencing factors, and had more systemic diseases of the digestive system, endocrine metabolic system, and cardiovascular system(p<0.05). CONCLUSION: We revealed the impact of age on the characteristics of rosacea, which indicated that the clinical features of rosacea are more complex and more difficult to treat in females over the age of 45.
