Changes of psychiatric parameters and their relationships by oral isotretinoin in acne patients.

J Dermatol. 2009 May; 36(5): 255-61Hahm BJ, Min SU, Yoon MY, Shin YW, Kim JS, Jung JY, Suh DHOral isotretinoin is a highly effective agent for the treatment of moderate to severe acne, but ever since oral isotretinoin was introduced as a modality for acne, the relationship between oral isotretinoin therapy and psychiatric problems, especially depression, has been controversial. The purposes of this study were to know the acute effects of oral isotretinoin therapy on psychiatric symptoms and to investigate the relationships among them, which have not been reported in the published work. This cohort study included 38 acne patients who started oral isotretinoin therapy. Individual patients were examined before administering oral isotretinoin and 2 and 8 weeks after commencement. Acne severity was graded using the Leeds revised acne grading system. Acute psychiatric effects of oral isotretinoin were assessed using a questionnaire authorized by two psychiatrists. This questionnaire included assessments of acne-related quality of life (Assessment of the Psychological and Social Effects of Acne [APSEA]), depression (Beck's depression inventory [BDI]), anxiety (Beck's anxiety inventory [BAI]) and psychopathology (Symptomchecklist-90-revised [SCL-90-R]). Acne grading and APSEA showed similar change patterns. Both improved after 8 weeks of oral isotretinoin treatment. On the other hand, the severity of depression decreased after 2 weeks of treatment. A significant correlation was found between BDI and APSEA, but no correlation was found between BDI and acne grade. These results indicate that oral isotretinoin therapy alleviates depressive symptoms. Improvements in depression are directly related to acne-related life quality improvements rather than to improvement in acne grade.

The efficacy of topical 2% green tea lotion in mild-to-moderate acne vulgaris.

J Drugs Dermatol. 2009 Apr; 8(4): 358-64Elsaie ML, Abdelhamid MF, Elsaaiee LT, Emam HMBACKGROUND: Botanical extracts and preparations have been used in different pathological conditions with success. An important group of phytochemical phenolic compounds are the catechins found in green tea. Acne is a widely occurring inflammatory condition that is estimated to affect 40 to 50 million Americans. Finding an effective, safe, cost-effective and well-tolerated treatment is the challenge. OBJECTIVE: To determine the efficacy of 2% green tea lotion in mild-to-moderate acne vulgaris. METHODS: Twenty patients fulfilling enrolment criteria were included. Green tea was given and applied twice daily for a period of 6 weeks. The patients were seen every 2 weeks to evaluate the lesions and any side effects. To determine efficacy on acne severity, the authors used both total lesion count (TLC) and their devised severity index (SI). Total lesions count (TLC) was calculated as papules + pustules while SI was scaled with numbers (1, 2 or 3) correlating to TLC in order of increasing intensity. TLC < 10 was given an SI of 1, TLC 10-20 was given an SI of 2 and TLC > 20 was given an SI of 3. RESULTS: The mean total lesion count (TLC) decreased from 24 before the treatment to 10 after 6 weeks after treatment, a reduction of 58.33%. The difference was statistically significant (P < 0.0001, 95% confidence interval [CI] of the difference = 8.58 - 19.42). The mean severity index (SI) decreased from 2.05 before treatment to 1.25 after 6 weeks treatment, a decrease of 39.02%. The difference was statistically significant (P < 0.0001, confidence interval [CI] of the difference = 0.54-1.26). Conclusion: Topical 2% green tea lotion is an effective, cost-effective treatment for mild-to-moderate acne vulgaris.

Increased interferon-gamma, interleukin-12p40 and IL-8 production in Propionibacterium acnes-treated peripheral blood mononuclear cells from patient with acne vulgaris Host response but not bacterial

J Dermatol Sci. 2009 Apr 16; Sugisaki H, Yamanaka K, Kakeda M, Kitagawa H, Tanaka K, Watanabe K, Gabazza EC, Kurokawa I, Mizutani HBACKGROUND: Acne vulgaris is a multifactorial inflammatory disease of the sebaceous follicles of the face and torso that frequently occurs in adolescence. Initially, acne starts as a non-inflammatory comedo. Subsequently, inflammatory reactions evolve to pustules, granulomas and cystic lesions. Many pathogenic mechanisms have been proposed including sebum excretion, obstruction of hair follicles, impaired keratinization of hair epithelium, bacterial overgrowth and immunological mechanisms; the role of Propionibacterium acnes (P. acnes) is particularly important. Facultative anaerobic gram-positive rods have been implicated in acne pathogenesis. However, the host immune response to P. acnes has not been as yet elucidated. OBJECTIVES: The aim of the present study is to evaluate the importance of the immune response to P. acnes and the bacteriological factor in the pathogenesis of acne. METHODS: P. acnes isolated from acne lesions and healthy volunteers skin were cultured. The peripheral blood mononuclear cells (PBMC) from acne patients or healthy volunteers were stimulated with viable P. acnes, and cytokine production was evaluated using RT-PCR and ELISA. RESULTS: IFN-gamma, IL-12p40, and IL-8 mRNA and protein production were significantly increased in PBMC from acne patients compared to that from normal donors. However, different P. acnes species isolated from acne lesions or normal subjects showed no difference in cytokines production from acne patients and normal subjects PBMC. CONCLUSIONS: The inflammatory response of acne appears to be attributable to P. acnes-induced host immune response rather than P. acnes strains from normal skin or acne lesions.
