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 inflammatory disease of the pilosebasea follicle. Although the cause of acne vulgaris is not known for certain but there are several pathogenesis suspected to have some effects on the occurrence of acne vulgaris, inter alia the increase in sebum production which is controlled by androgen hormones. Stimulation of androgen hormone production is associated with elevated level of insulin-like growth factor-1 (IGF-1). Increased IGF-1 is correlated positively with body mass index (BMI). In general, acne vulgaris begins at age 12-15 years and most occur in adolescents aged 15-18 years. This study was aimed to determine the relationship between BMI and the incidence rate of acne vulgaris in students at SMA Frater Don Bosco Manado (senior high school). This was an analytical survey observation with a cross sectional design. Subjects were 69 students obtained by using systematic random sampling. Of the 69 students suffered from acne vulgaris, there were 8 (11.6%) with thin BMI; 50 (72.5%) with normal BMI; and 11 (15.9%) with fat and obese BMI. Conclusion: There was no significant association between BMI and the incidence of acne vulgaris among the students at SMA Frater Don Bosco Manado.Keywords: body mass index, acne vulgaris Abstrak: Akne vulgaris adalah penyakit radang kronis pada folikel pilosebasea. Walaupun penyebab dari akne vulgaris belum diketahui pasti namun terdapat beberapa patogenesis yang diduga berpengaruh pada timbulnya akne vulgaris, salah satunya yaitu peningkatan produksi sebum di bawah kontrol hormon androgen. Stimulasi produksi hormon androgen berhubungan dengan peningkatan kadar insulin-like growth factor-1 (IGF-1). Peningkatan IGF-1 berkorelasi positif dengan indeks massa tubuh (IMT). Umumnya akne vulgaris dimulai pada usia 12-15 tahun dan terbanyak pada remaja usia 15-18 tahun. Penelitian ini bertujuan untuk mengetahui hubungan antara IMT dan angka kejadian akne vulgaris pada siswa-siswi di SMA Frater Don Bosco Manado. Jenis penelitian ialah observasi analitik survei dengan desain potong lintang. Subyek penelitian ialah siswa-siswi di SMA Frater Don Bosco Manado diperoleh dengan pengambilan sampel secara acak sistematis. Pada 69 subyek dengan akne vulgaris, terdapat 8 orang (11,6%) dengan IMT kurus; 50 orang (72,5%) dengan IMT normal; dan 11 orang (15,9%) dengan IMT gemuk dan obesitas. Simpulan: Tidak terdapat hubungan bermakna antara IMT dan angka kejadian akne vulgaris pada siswa-siswi di SMA Frater Don Bosco Manado.Kata kunci: indeks massa tubuh, akne vulgaris

Survivin, a member of the inhibitor of apoptosis protein family, has an important role in cell cycle regulation. Insulin-like growth factor-I (IGF-I) is a polypeptide hormone with wide range of biologic effects including stimulation of lipogenesis in sebaceous glands. Their overexpression in some fibrotic disorders suggests a possible implication of both IGF-I and survivin in the pathogenesis of acne and/or acne scars. The current study aimed to assess and correlate serum levels of IGF-I and survivin in patients with active acne vulgaris and postinflammatory acne scars and to evaluate their lesional expressions in comparison to healthy controls. Serum IGF-I and survivin were estimated using commercially available ELISA kits and their tissues expressions were investigated using Western blotting. Our findings suggest that IGF-I and survivin could play potential roles in the pathogenesis of active acne vulgaris and more importantly in postinflammatory acne scars with significant positive correlation coefficient between serum levels of IGF-I and survivin which support IGF-I-/PI3K-/AKT-mediated downregulation of nuclear expression of FoxO transcription factors resulting in enhanced survivin expression.
