    • Front Pharmacol. 2023 Mar 1;14:1092473. doi: 10.3389/fphar.2023.1092473. eCollection 2023. ABSTRACT Background: Rosacea is a common facial skin inflammatory disease featured by hyperactivation of mTORC1 signaling in the epidermis. Due to unclear pathogenesis, the effective treatment options for rosacea remain limited. Methods: Weighted gene co-expression network analysis (WGCNA) analyzed the relationship between epidermis autophagy and mTOR pathways in rosacea, and further demonstrated it through immunofluorescence and qPCR analysis. A potential therapeutic agent for rosacea was predicted based on the key genes of the WGCNA module. In vivo and in vitro experiments were conducted to verify its therapeutic role. Drug-target prediction (TargetNet, Swiss, and Tcmsp) and molecular docking offered potential pharmacological targets. Results: WGCNA showed that epidermis autophagy was related to the activation of mTOR pathways in rosacea. Next, autophagy was downregulated in the epidermis of rosacea, which was regulated by mTOR. In addition, the in vivo experiment demonstrated that autophagy induction could be an effective treatment strategy for rosacea. Subsequently, based on the key genes of the WGCNA module, epigallocatechin-3-gallate (EGCG) was predicted as a potential therapeutic agent for rosacea. Furthermore, the therapeutic role of EGCG on rosacea was confirmed in vivo and in vitro. Finally, drug-target prediction and molecular docking revealed that AKT1/MAPK1/MMP9 could be the pharmacological targets of EGCG in rosacea. Conclusion: Collectively, our findings revealed the vital role of autophagy in rosacea and identified that EGCG, as a therapeutic agent for rosacea, attenuated rosacea-like inflammation via inducing autophagy in keratinocytes.

    • Cureus. 2023 Feb 15;15(2):e35011. doi: 10.7759/cureus.35011. eCollection 2023 Feb. ABSTRACT The most common cutaneous manifestations of alcoholism include urticarial reaction, flushing, porphyria cutanea tarda, psoriasis, rosacea, seborrheic dermatitis, and pruritus. Here, we present a case of a young male with a history of alcohol abuse who presented with non-blanching, petechial, and perifollicular macular rash secondary to vitamin C deficiency in view of poor oral intake. The rash improved significantly with vitamin C supplementation. Although rare in developed countries, clinicians should keep vitamin C deficiency as a differential diagnosis for skin rash in alcohol consumers.
