Propionibacterium acnes ATCC 11827 and Methicillin-Resistant Staphylococcus aureus ATCC BAA-1683 are bacteria that cause skin infections, namely acne vulgaris and skin and soft tissue infection/SSTI. The increase in the number of resistant bacterial strains, such as MRSA,  requires the search for alternative antibiotics, including using natural ingredients. Red yeast rice is a product of rice fermentation by Monascus purpureus, which is known to have antibacterial, antifungal, antitumor, antioxidant, anti-inflammatory, anti-cholesterol and immunomodulator. This study aims to determine the antibacterial activity of several red yeast rice extracts against these bacteria that cause skin infections. The research was carried out through the stages of collecting materials and identifying the yeast isolates, extracting of red yeast rice, phytochemical screening of red yeast rice extract, confirmation of bacterial test, preparation of bacterial test suspension, testing for bacterial resistance, testing for antibacterial activity of red yeast rice extract and determining the value of Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) of the most active extract. The results showed that the ethyl acetate and ethanol extracts had antibacterial activity against P. acnes ATCC 11827 and MRSA ATCC BAA-1683. Both extracts contain compounds from the polyphenols, flavonoids, quinones and saponins group. Ethyl acetate extract was the most active extract with MIC values against P. acnes ATCC 1182 and MRSA ATCC BAA-1683 of 50 mg/mL and 12.5 mg/mL. The MBC values of ethyl acetate extract against these bacterial tests were 100 mg/mL and 25 mg/mL. The ethyl acetate extract is more active against MRSA ATCC BAA-1683 than against P. acnes ATCC 11827. From the results of this study it is known that red yeast rice has activity against bacteria that cause skin infections, especially against MRSA

Acne vulgaris é uma das patologias dermatológicas mais comuns na população geral, principalmente em adolescentes e jovens adultos. Esta patologia afeta os folículos pilossebáceos através de processos de hiperqueratose, hipersecreção sebácea, colonização microbiana (Propionibacterium acnes e Malassezia furfur) e mecanismos imunológicos e pode ser descrita tanto como inflamatória (pápulas, pústulas ou nódulos) ou não inflamatória (comedões abertos ou fechados). Apesar de não existir mortalidade associada, existe normalmente significativa morbilidade física e psicológica, como cicatrizes permanentes, baixa autoestima, depressão e ansiedade. A fisiopatologia desta doença é multifatorial, sendo que vários estudos provam a importância de vários fatores genéticos e não genéticos, como diversos mecanismos reguladores endócrinos e a dieta, no aparecimento da acne. Estudos associam a dieta ocidental (carbohidratos hiperglicémicos, leite e lacticínios e gorduras saturadas) e o índice de massa corporal excessivo (excesso de peso e obesidade) ao aparecimento de Acne Vulgaris, sendo que existe evidência do papel da hiperinsulinémia e da resistência à insulina nesta associação. Será assim avaliada nesta dissertação a atual literatura que aborda a fisiopatologia da Acne Vulgaris, com especial foco na relação entre os reguladores endócrinos (androgénios e insulin-like growth factor 1) e reguladores celulares (Forkhead box protein 01, kinase proteica Akt) e os diferentes alimentos da dieta, dando relevância às peculiaridades da dieta ocidental e do seu papel no aparecimento de acne nas diferentes pool´s genéticas mundiais. Será também explorada a relação entre o índice de massa corporal e o aparecimento de acne, bem como a importância das adipocinas na etiologia da acne. O objetivo deste trabalho é contribuir para o melhor conhecimento da fisiopatologia desta interessante e frequente patologia. Sendo uma área muito estudada, torna-se fulcral a existência de artigos de revisão, que compilem, sintetizem e ao mesmo tempo analisem criticamente a literatura científica existente.

Abstract: Acne vulgaris is a chronic skin condition involving inflammation of the pilosebaceous follicle. The highest prevalence of acne vulgaris is at the age of 16-17 years. Pathogenic factors contributing to the development of acne vulgaris include increased sebum production, pilosebaceous follicular blockage, and increased colonization of Propionibacterium acnes. Personal hygiene is suggested as an important factor that needs to be maintained in acne prevention. Males tend to lack of awareness to seek information and health services in dealing with acne problems. This study was aimed to evaluate the relationship between facial washing and the incidence of acne vulgaris in adolescent males in Manado. This was an analytical and observational study using a cross-sectional design. Subjects were male students of 3rd grade at SMA Negeri 9 Manado, aged 16-19 years old, and met the inclusion and exclusion criteria, with a total number of 95 students. Subjects who washed their faces 2-3 times a day were 38 students (40%) while those who washed their faces less than twice or more than thrice a day were 57 students (60%). Subjects with no or mild acne vulgaris were 39 students (41.1%), while those with moderate to severe acne vulgaris were 56 students (58.9%). The chi-square showed a p-value of 0.004 for the relationship between the frequency of facial washing and the incidence of acne vulgaris. In conclusion, there was a significant relationship between facial washing and the incidence of acne vulgaris in adolescent males in Manado.Keywords: facial washing, acne vulgaris Abstrak: Akne vulgaris merupakan peradangan kronis folikel pilosebasea dengan prevalensi tertinggi pada usia 16-17 tahun. Faktor yang memengaruhi terjadinya akne vulgaris antara lain peningkatan produksi sebum, penyumbatan folikel pilosebasea, dan peningkatan kolonisasi bakteri Propionibacterium acnes. Kebersihan diri merupakan faktor penting yang perlu dijaga sebagai salah satu usaha untuk mencegah timbulnya akne. Laki-laki cenderung kurang memiliki kesadaran untuk mencari informasi dan pelayanan kesehatan dalam menangani masalah akne.

Background Global reports show that the antimicrobial-resistance of Propionibacterium acnes isolated from patients with acne vulgaris is becoming a large problem, making it necessary to find new therapeutic drugs. Methods In this study, 23 clinical isolates of P. acnes have been identified by MaldiToff and specific PCR. The susceptibility of theses strains to antibiotics (clindamicin, erytromycin and tetracicline) and to bacteriocin (AS-48) has been established, using the CECT 5684 strain as reference. Moreover, we have investigated the potential of several chemical compounds to bolster the activity of AS-48. Finally, the effectivity of four different formulations containing AS-48 and lysozyme have been evaluated on the surface of swine-ear skin previously inoculated with P. acnes CECT5684 strain. Results. The results presented in this work probe that AS-48 has a significant bactericidal activity against the 23 clinical isolates of P. acnes, including isolates resistant to one or more common antibiotics used in the treatment of acne. Antibacterial synergy of AS-48 with other chemical compounds has been demonstrated, as was the effect of lysozyme and to a lesser extent with palmitic acid. Likewise, the use of a combination therapy into a cream formulation, resulted in large decrease in the number of viable P. acnes counts in an experiemental model. Conclusion. Once more these studios support that compositions comprising bacteriocins displaying antibacterial activity, must be considered an approach for medical and pharmaceutical purposes. These applications are particularly promising in light of emerging antibiotic resistance across bacteria involved in treatment of dermatological disease as acne vulgaris.
