Rosacea: an update on medical therapies.

Rosacea: an update on medical therapies. Skin Therapy Lett. 2014 Jun;19(3):1-4 Authors: Chang BP, Kurian A, Barankin B Abstract Rosacea is a common, chronic cutaneous condition that affects the face. Two topicals and one oral medication are currently approved for the treatment of rosacea, including azelaic acid, metronidazole, and sub-antimicrobial dose of doxycycline. Identification of subtypes can help guide treatment strategies. It is essential for psychosocial implications of rosacea to be considered and conservative management, such as nonpharmacologic routine skin care, must form an important part of the overall care. Recently, new insights into the pathophysiology of rosacea have led to the emergence of etiologically oriented treatments. Ivermectin, an acaricidal agent that has been shown to be effective against rosacea refractory to other therapies, is currently in Phase 3 trials. Brimonidine, which was US FDA approved last year and recently sanctioned by Health Canada, has filled an essential therapeutic void in the targeted treatment of diffuse facial erythema.

Skin is the largest peripheral endocrine organ and functions as a hormone target and endocrine gland. A cutaneous hypothalamus-pituitary-adrenal (HPA)-like axis enables the skin to respond to stress and regulates its steroidogenic activity. The pilosebaceous unit is a site for production and metabolism of a number of steroid hormones, including stress and sex hormones. This is an overview of the important role that the cutaneous HPA-like-axis plays in the pathogenesis and treatment of inflammatory pilosebaceous disorders, including acne, rosacea, seborrheic dermatitis, and hidradenitis suppurativa.

Conclusions: RCM enables anti-inflammatory effect monitoring of topical ivermectin by determining mite presence. Quantifying exact mite number, and inflammatory and vascular characteristics is challenging due to device limitations. In its current form, RCM seems of limited value for noninvasive follow-up of rosacea in clinical practice. PMID: 32189533 [PubMed - as supplied by publisher]

Abstract Rosacea is a chronic and relapsing inflammatory cutaneous disorder with highly variable prevalence worldwide that adversely affects the health of patients and their quality of life. However, the molecular characterization of each rosacea subtype is still unclear. Furthermore, little is known about the role of long noncoding RNAs (lncRNAs) in the pathogenesis or regulatory processes of this disorder. In the current study, we established lncRNA-mRNA coexpression networks for three rosacea subtypes (erythematotelangiectatic, papulopustular, and phymatous) and performed their functional enrichment analyses us...

Rosacea is a common, chronic inflammation of sebaceous gland-rich facial skin characterized by severe skin dryness, elevated pH, transepidermal water loss, and decreased hydration levels. Until now, there has been no thorough molecular analysis of permeability barrier alterations in the skin of rosacea patients. Thus, we aimed to investigate the barrier alterations in papulopustular rosacea (PPR) samples compared to healthy sebaceous gland-rich (SGR) skin, using RNASeq analysis (n=8). Pathway analyses by Cytoscape ClueGo revealed 15 significantly enriched pathways related to skin barrier formation.

Public health authorities are advising frequent hand washing and social distancing, especially in the absence of confirmatory testing for COVID-19. I don’t have any wisdom to add to these practices. Vaccines are in the works, as are anti-viral drugs—nothing to add here, either. But let me reiterate what we do in the Wheat Belly and Undoctored lifestyles. In general, we do not treat diseases; we correct the factors that allow disease to emerge in the first place—a big difference. Take rheumatoid arthritis, for example. In conventional healthcare, the joint pain and swelling of rheumatoid arthritis are...

AbstractPurpose of ReviewOngoing investigations of the human skin microbiome strongly suggest a connection to skin diseases and skin health. This review provides an overview of recent literature on the skin microbiome in relation to skin diseases, with a specific focus on common inflammatory skin conditions, such as atopic dermatitis, psoriasis, hidradenitis suppurativa, acne, and rosacea.Recent FindingsIn healthy subjects, the skin microbiome mediates fundamental processes involving the immune response and epidermal development and differentiation. Microbiome characteristics in inflammatory skin diseases differ depending ...

ABSTRACT Purpose: To compare the impact of ocular changes between systemic treatment with doxycycline and low-dose oral isotretinoin in patients with moderate-to-severe papulopustular rosacea. Methods: Patients were randomized to receive either isotretinoin 0.3-0.4 mg/kg (group A) or doxycycline 100 mg/day (group B) for 16 weeks. Ocular symptoms were searched and evaluated, including best-corrected visual acuity (BCVA), Schirmer test, breakup time, rose bengal staining score, and meibomian gland dysfunction grading. The patients were retested at the end of treatment. Results: The present study included 39 patients (30 fema...
