    Acne vulgaris is a common inflammatory skin condition that presents management difficulties to cosmetic surgeons. Acute management and treatment focuses on early diagnosis as well as treatment with topical agents, oral antibiotics, hormonal therapy,and nonablative chemical peel and laser applications. The treatment of postinflammatory scarring must be individualized to address potential macular dyschromia, cystic lesions,epithelial bridges, or deep pitted scars. A review of interventional options is presented to apply to the spectrum of acne scarring as well as a review of the literature to address objectively published reports on efficacy.

    The strong bactericidal properties of lauric acid (C12:0), a middle chain-free fatty acid commonly found in natural products, have been shown in a number of studies. However, it has not been demonstrated whether lauric acid can be used for acne treatment as a natural antibiotic against Propionibacterium acnes (P. acnes), which promotes follicular inflammation (inflammatory acne). This study evaluated the antimicrobial property of lauric acid against P. acnes both in vitro and in vivo. Incubation of the skin bacteria P. acnes, Staphylococcus aureus (S. aureus), and Staphylococcus epidermidis (S. epidermidis) with lauric acid yielded minimal inhibitory concentration (MIC) values against the bacterial growth over 15 times lower than those of benzoyl peroxide (BPO). The lower MIC values of lauric acid indicate stronger antimicrobial properties than that of BPO. The detected values of half maximal effective concentration (EC50) of lauric acid on P. acnes, S. aureus, and S. epidermidis growth indicate that P. acnes is the most sensitive to lauric acid among these bacteria. In addition, lauric acid did not induce cytotoxicity to human sebocytes. Notably, both intradermal injection and epicutaneous application of lauric acid effectively decreased the number of P. acnes colonized with mouse ears, thereby relieving P. acnes-induced ear swelling and granulomatous inflammation. The obtained data highlight the potential of using lauric acid as an alternative treatment for antibiotic therapy of acne vulgaris. PMID:19387482

    Acne vulgaris is a disease of the pilosebaceous unit that affects nearly all persons to some degree during the teenage years. It is a disease that should be treated because of the anxiety and disfigurement it causes in the affected patient. Acne therapy is directed against the three probable pathogenic processes in acne: (1) abnormal keratinization of the sebaceous follicle, (2) excessive production of sebum, and (3) proliferation of bacteria in the follicle. Superficial acne consisting of comedones and small papulopustules will frequently respond to topical therapy such as retinoic acid, benzoyl peroxide, and topical antibiotics. Deeper lesions require systemic antibiotics of which tetracycline is the drug of choice. Severe, recalcitrant cystic acne usually responds well to the oral retinoid, isotretinoin. The severe teratogenic effects of isotretinoin on a developing fetus make this a risky drug to prescribe for women with childbearing potential. In such cases the greatest precautions should be taken to avoid pregnancy during a course of isotretinoin. Such precautions include pregnancy testing, contraceptive counseling, and the use of at least two effective forms of birth control in sexually active women.

    Acne may present in neonates, infants, and small children. Neonatal and infantile acne vulgaris are not considered to be rare. The presentation of acne in this patient population sometimes represents virilization and may portend later development of severe adolescent acne. Neonatal and infantile acne vulgaris must be distinguished from other cutaneous disorders seen in newborns and infants. Infantile acne tends to be more pleomorphic and inflammatory, thus requiring more vigorous therapy than neonatal acne.

    Nicotinamide and clindamycin gels are two popular topical medications for acne vulgaris. This study aimed to compare efficacy of the topical 4% nicotinamide and 1% clindamycin gels in these patients. In this randomized, double-blind clinical trial, patients with moderate inflammatory facial acne vulgaris were randomly allocated to receive either topical 4% nicotinamide (n = 40) or 1% clindamycin gels (n = 40) twice daily. In each group, they were further categorized in two subgroups with oily and non-oily types of facial skin. The Cook's acne grade was determined at baseline and at weeks 4 and 8 post treatment. Acne grade decreased from an average of 5.93 ± 0.83 at baseline to 4.03 ± 1.33 at week 4 and 2.08 ± 1.59 at week 8 in nicotinamide receivers, and from an average of 5.70 ± 0.94 at baseline to 3.85 ± 1.66 at week 4 and 2.03 ± 1.53 at week 8 in the clindamycin group (within-group P < 0.001, between-group P > 0.05). Comparing with each other, nicotinamide and clindamycin gels were significantly more efficacious in oily and non-oily skin types, respectively. No major side effect was encountered by any patient. Skin type is a significant factor in choosing between topical nicotinamide and clindamycin in patients with acne vulgaris.

    Androgens play an important part in the development of acne vulgaris. Androgen levels in patients with acne are higher than those in controls and people with the androgen insensitivity syndrome do not develop acne. Local factors other than androgen plasma levels, also play a part in the development of acne. The skin contains enzymes that convert precursor hormones to the more potent androgens such as testosterone and dihydrotestosterone. Androgen synthesis can therefore be regulated locally. The effects of androgens on the skin are the result of circulating androgens and enzyme activity in local tissues and androgen receptors. Acne is a clinical manifestation of some endocrine diseases. The polycystic ovary syndrome has the highest prevalence. In women with acne that persists after puberty, in 10-200% of cases polycystic ovary syndrome is later diagnosed. The mechanism of hormonal anti-acne therapy may work by blocking the androgen-production (oestrogens) or by blocking the androgen receptor (cyproterone, spironolactone).

    Azelaic acid (AzA) 15% gel is approved for the treatment of rosacea in the US, but also has approval for the treatment of acne vulgaris in many European countries where it has demonstrated success. Two randomized, multicenter, controlled clinical trials compared the effects of AzA 15% gel with those of topical benzoyl peroxide 5% or topical clindamycin 1%, all using a twice-daily dosing regimen. The primary endpoint in the intent-to-treat analysis was a reduction in inflammatory papules and pustules. AzA 15% gel resulted in a 70% to 71% median reduction of facial papules and pustules compared with a 77% reduction with benzoyl peroxide 5% gel and a 63% reduction with clindamycin. AzA 15% gel was well-tolerated. In addition, a 1-year European observational study conducted by dermatologists in private practice evaluated the safety and efficacy of AzA 15% gel used as monotherapy or in combination with other agents in more than 1200 patients with acne. Most physicians (81.9%) described an improvement in patients' symptoms after an average of 34.6 days, and 93.9% of physicians reported patient improvement after an average of 73.1 days. Both physicians and patients assessed AzA 15% gel to be effective with 74% of patients being "very satisfied" at the end of therapy. AzA 15% gel was considered "well-tolerated" or "very well-tolerated" by 95.7% of patients. The majority of patients were more satisfied with AzA than with previous therapies. AzA 15% gel represents a new therapeutic option for the treatment of acne vulgaris.

    Background This study was conducted to evaluate the immunohistochemical (IHC) expression of interleukin 8 (IL-8) in skin biopsies of inflammatory acne vulgaris (IAV) in an attempt to understand the disease pathogenesis. Materials and methods A total of 58 biopsies, 29 from lesional IAV and 29 normal non lesional sites were immunostained for IL-8. The intensity of staining was evaluated in the epidermis and dermis and was scored as mild, moderate and severe. The expression was correlated with the clinical grade, disease course and histological changes. Results IL-8 immunoreactivity was expressed in lesional IAV compared to non lesional skin biopsies (p < 0.001). Increased expression was significantly associated with epidermal hyperplasia and follicular hyperkeratosis (p < 0.001). In addition, the more pronounced IL-8 expression of the dermal endothelial cells and neutophilic inflammatory infiltrate correlated with dermal angiogenesis and the extent of dermal inflammatory response (p < 0.001). Moreover, increased dermal immunoreactivity paralleled progressive course (p = 0.02) but not the duration of the disease. Conclusion We were able to demonstrate altered immunoreactivity of IL-8 in IAV compared to normal skin. Targeted therapy to block IL-8 production may hold promise in limiting the deleterious effects of IL-8-mediated inflammatory response and angiogenesis. PMID:17263887

    The 1450-nm diode laser has been found to be effective for the treatment of inflammatory acne in USA, Europe and Japan. However, there is no report on its efficacy in Chinese acne vulgaris patients. We conduct this pilot study to evaluate the efficacy and safety of the 1450-nm diode laser in the treatment of inflammatory facial acne vulgaris in Chinese patients. Nineteen patients with inflammatory facial acne were treated with the 1450-nm diode laser at 4- to 6-week intervals. Clinical photographs and lesion counts were obtained at baseline and after each treatment. Subjective evaluation of response to treatment and pain was assessed using a questionnaire. In our study, clinical improvement was seen in all patients and was generally dramatic. Lesion counts decreased 34% after one treatment (p<0.01), 56% after two treatments (p<0.01), and 81% after three treatments (p<0.01). However, the treatment-related pain was comparatively hard to be tolerated in Chinese patitents, and the other main adverse effect was the hyper-pigmentation after treatments (36.84%, 7/19).

    Acne vulgaris, a multi-factorial disease, is one of the most common skin diseases, affecting an estimated 80% of Americans at some point during their lives. The gram-positive and anaerobic Propionibacterium acnes (P. acnes) bacterium has been implicated in acne inflammation and pathogenesis. Therapies for acne vulgaris using antibiotics generally lack bacterial specificity, promote the generation of antibiotic-resistant bacterial strains, and cause adverse effects. Immunotherapy against P. acnes or its antigens (sialidase and CAMP factor) has been demonstrated to be effective in mice, attenuating P. acnes-induced inflammation; thus, this method may be applied to develop a potential vaccine targeting P. acnes for acne vulgaris treatment. This review summarizes reports describing the role of P. acnes in the pathogenesis of acne and various immunotherapy-based approaches targeting P. acnes, suggesting the potential effectiveness of immunotherapy for acne vulgaris as well as P. acnes-associated diseases.

    Background Acne vulgaris is a chronic skin disorder leading to inflammation as a result of the production of reactive oxygen species due to the active involvement of Propionibacterium acnes (P. acnes) in the infection site of the skin. The current study was designed to assess the potential of the leaf extract of Syzygium jambos L. (Alston) and its compounds for antibacterial and anti-inflammatory activity against the pathogenic P. acnes. Methods The broth dilution method was used to assess the antibacterial activity. The cytotoxicity investigation on mouse melanocyte (B16-F10) and human leukemic monocyte lymphoma (U937) cells was done using sodium 3’-[1-(phenyl amino-carbonyl)-3,4-tetrazolium]-bis-[4-methoxy-6-nitrobenzene sulfonic acid hydrate (XTT) reagent. The non-toxic concentrations of the samples was investigated for the suppression of cytokines interleukin 8 (IL 8) and tumour necrosis factor (TNF α) by testing the supernatants in the co-culture of the human U937 cells and heat killed P. acnes using enzyme immunoassay kits (ELISA). The statistical analysis was done using the Graph Pad Prism 4 program. Results Bioassay guided isolation of ethanol extract of the leaves of S. jambos led to the isolation of three known compounds namely; squalene, an anacardic acid analogue and ursolic acid which are reported for the first time from this plant. The ethanol extract of S. jambos and one of the isolated compound namely, anacardic acid analogue were able to inhibit the growth of P. acnes with a noteworthy minimum inhibitory concentration (MIC) value of 31.3 and 7.9 μg/ml, respectively. The ethanol extract and three commercially acquired compounds namely; myricetin, myricitrin, gallic acid exhibited significant antioxidant activity with fifty percent inhibitory concentration (IC50) ranging between 0.8-1.9 μg/ml which was comparable to that of vitamin C, the reference antioxidant agent.

    Stickl's method of oral treatment of acne vulgaris with antigens has been carried out on 26 test persons. During the treatment the number of comedones increased significantly and the number of papules decreased significantly. Biochemically, a significant increase of the free fatty acids and a significant decrease of the triglycerides could be demonstrated in the skin surface lipids, the total amount remaining unchanged. The following important conclusions for the pathogenesis of acne may be drawn: 1. The living conditions for Corynebacterium acnes on the surface of the skin or in the ducts of sebaceous glands respectively are influenced by the immunological system of the host. 2. The free fatty acids have a comedogenic effect in vivo. 3. The free fatty acids are not responsible for the development of inflammatory acne efflorescences.

    trials in two meta-analyses, with two trials in each meta-analysis. The categories of CAM included herbal medicine, acupuncture, cupping therapy, diet, purified bee venom (PBV), and tea tree oil. A pharmaceutical company funded one trial; the other trials did not report their funding sources. Our main primary outcome was ’Improvement of clinical signs assessed through skin lesion counts’, which we have reported as ’Change in inflammatory and non-inflammatory lesion counts’, ’Change of total skin lesion counts’, ’Skin lesion scores’, and ’Change of acne severity score’. For ’Change in inflammatory and non-inflammatory lesion counts’, we combined 2 studies that compared a low- with a high-glycaemic-load diet (LGLD, HGLD) at 12 weeks and found no clear evidence of a difference between the groups in change in non-inflammatory lesion counts (mean difference (MD) −3.89, 95% confidence interval (CI) −10.07 to 2.29, P = 0.10, 75 participants, 2 trials, low quality of evidence). However, although data from 1 of these 2 trials showed benefit of LGLD for reducing inflammatory lesions (MD −7.60, 95% CI −13.52 to −1.68, 43 participants, 1 trial) and total skin lesion counts (MD −8.10, 95% CI −14.89 to −1.31, 43 participants, 1 trial) for people with acne vulgaris, data regarding inflammatory and total lesion counts from the other study were incomplete and unusable in synthesis. Data from a single trial showed potential benefit of tea tree oil compared with placebo in improving total skin lesion counts (MD −7.53, 95% CI −10.40 to −4.66, 60 participants, 1 trial, low quality of evidence) and acne severity scores (MD −5.75, 95% CI −9.51 to −1.99, 60 participants, 1 trial). Another trial showed pollen bee venom to be better than control in reducing numbers of skin lesions (MD −1.17, 95% CI −2.06 to −0.28, 12 participants, 1 trial).

    Appropriate cosmetics for skin cleansing are capable of contributing to a reduction of especially inflammatory lesions in acne-prone patients and to support pharmacological intervention in patients with manifest acne. Cleansing of acne-prone skin should employ acidified synthetic cleansers with a pH of 5.5 rather than soap. Furthermore, the ingredients of certain skin care products, i.e. nicotinamide, lactic acid, triethyl acetate/ethyllineolate, and prebiotic plant extracts, affect different mechanisms of acne pathogenesis and therefore may contribute to a decrease in acne lesions. At least some of these ingredients underscore the concept of evidence-based cosmetics. In contrast, the problem of acne lesions caused by comedogenic ingredients in cosmetics today is negligible.

    Propionibacterium acnes is an anaerobic bacterium that plays an important role in the pathogenesis of acne. Certain antibiotics that can inhibit P acnes colonization also have demonstrated anti-inflammatory activities in the treatment of acne, rosacea, and other noninfectious diseases. Decreased sensitivity of P acnes to antibiotics, such as erythromycin and tetracycline, has developed and may be associated with therapeutic failure. Benzoyl peroxide (BPO) is a nonantibiotic antibacterial agent that is highly effective against P acnes and for which no resistance against it has been detected to date. Retinoids are important components in combination therapy for acne, including use with antibiotics, and can serve as an alternative to these agents in maintenance therapy. By increasing our understanding of the multifaceted actions of antibiotics and the known clinical implications of antibiotic resistance, physicians can improve their decision making in prescribing these agents.

    Photodynamic therapy (PDT) with topical 5-aminolevulinic acid (ALA) was tested for the treatment of acne vulgaris. Patients with acne were treated with ALA plus red light. Ten percent water solution of ALA was applied with 1,5-2 h occlusion and then 18-45 J/cm2 630 nm light was given. Bacterial endogenous porphyrins fluorescence also was used for acne therapy. Treatment control and diagnostics was realized by fluorescence spectra and fluorescence image. Light sources and diagnostic systems were used: semiconductor laser (λ=630 nm, Pmax=1W), (LPhT-630-01-BIOSPEC); LED system for PDT and diagnostics with fluorescent imager (λ=635 nm, P=2W, p=50 mW/cm2), (UFPh-630-01-BIOSPEC); high sensitivity CCD video camera with narrow-band wavelength filter (central wavelength 630 nm); laser electronic spectrum analyzer for fluorescent diagnostics and photodynamic therapy monitoring (LESA-01-BIOSPEC). Protoporphyrin IX (PP IX) and endogenous porphyrins concentrations were measured by fluorescence at wavelength, correspondingly, 700 nm and 650 nm. It was shown that topical ALA is converted into PP IX in hair follicles, sebaceous glands and acne scars. The amount of resulting PP IX is sufficient for effective PDT. There was good clinical response and considerable clearance of acne lesion. ALA-PDT also had good cosmetic effect in treatment acne scars. PDT with ALA and red light assist in opening corked pores, destroying Propionibacterium acnes and decreasing sebum secretion. PDT treatment associated with several adverse effects: oedema and/or erytema for 3-5 days after PDT, epidermal exfoliation from 5th to 10th day and slight pigmentation during 1 month after PDT. ALA-PDT is effective for acne and can be used despite several side effects.

    Background: Regardless of the overall association between diet and acne which cannot be easily ignored, there might be an association between specific nutrients and acne development or improvement. Objectives: The aim of this study was to assess the effect of dietary intake of sunflower seeds on acne severity and the pattern of acne lesions. Patients and Methods: In a randomized controlled trial, 50 patients aged 15 - 30 years old with acne vulgaris were enrolled through consecutive convenient sampling, in a dermatology clinic in Ardabil, Iran. They were randomly allocated into two trial arms. Those in the control group were asked to stop eating sunflower seeds if they did before. In the intervention group, they consumed 25 g sunflower-containing food daily for seven days. The primary outcome of interest was 10% increase/decrease in the baseline acne severity index (ASI), sustained to the end of the follow-up period on day 14. Results: The mean ASI did not change significantly through the study period in the control group, but it increased in the sunflower group from 62 at the baseline to 86.8 after two weeks (P < 0.001). The ASI mean change was 24.8 in the sunflower group compared to 4.9 in the control group (P < 0.001). The global acne grading score (GAGS) did not significantly change in any of the groups and the difference in the change of GAGS was not significant between the groups (2.4 in the sunflower group versus 1.6 in the control group). Twenty two subjects (88%) in the sunflower group versus 9 (36%) in the control group had at least 10% increment in ASI throughout the follow-up period (P < 0.001). The relative risk of developing the primary outcome in taking the sunflower seed intervention was 2.4 (95% CI: 1.4 - 4.2). The observed risk difference was 0.52 (95% CI: 0.29 - 0.75). Conclusions: Sunflower seed intake appears to aggravate acne vulgaris; however, further evidence is needed to ban sunflower seed intake in patients with acne. Considering the

    The management of acne vulgaris in the setting of pregnancy raises important clinical considerations regarding the efficacy and safety of acne treatments in this special patient population. Particular challenges include the absence of safety data, discrepancy in safety data between different safety rating systems, and lack of evidence-based recommendations for the treatment of acne during pregnancy. Nonetheless, many therapeutic options exist, and the treatment of acne in pregnant women can be safely and often effectively accomplished. For mild or moderate disease, patients can be treated with topical antimicrobial agents, anti-inflammatory agents, as well as glycolic and salicylic acid. Several topical agents, notably benzoyl peroxide, previously viewed as potentially dangerous are cited by many sources as being considered safe. When necessary, systemic therapies that can be safely added include penicillins, amoxicillin, cephalosporins, erythromycin, clindamycin, and tetracyclines or sulfonamides, depending on the stage of fetal development. Adjunct therapy may include phototherapy or laser treatments. Physicians should work with this often highly motivated, safety-conscious patient population to tailor an individualized treatment regimen. This treatment regimen will likely shift throughout the different stages of fetal development, as distinct safety considerations are raised prior to conception as well as during each of the trimesters of pregnancy. Important considerations regarding acne management in breast-feeding mothers is also discussed.

    Background: Acne vulgaris causes erythematous papulopustular lesions in active stage and often leave behind residual scarring and pigmentation. Its onset in adolescence may add to the emotional and psychological challenges experienced during this period. Aims: To assess the impact of acne on the various psychosocial domains of daily life. Materials and Methods: This was a prospective, cross-sectional study done in the dermatology out-patient department of a tertiary care hospital from January to March 2015. A total of 100 consecutive, newly diagnosed patients of acne vulgaris, aged 15 years and above were included in this study. The relationship between acne vulgaris and its sequelae was analyzed with ten different domains of daily life by using dermatology life quality index (DLQI) questionnaire. Results: Females (56%), 15–20 year olds (61%), facial lesions (60%), and Grade II acne (70%) were most common. Acne scars were noted in 75% patients, whereas 79% cases had post-acne hyperpigmentation. Thirty-seven percent patients had DLQI scores of (6–10) interpreted as moderate effect on patient's life. Statistically significant correlation (P < 0.05) found were as follows: Physical symptoms with grade of acne; embarrassment with site and grade of acne; daily activities with grade of acne and post-acne pigmentation; choice of clothes with site of acne; social activities with gender, site and grade of acne; effect on work/study with grade of acne; interpersonal problems with site and post-acne pigmentation; sexual difficulties with grade of acne. Limitation: It was a hospital-based study with small sample size. Conclusion: Significant impact of acne and its sequelae was noted on emotions, daily activities, social activities, study/work, and interpersonal relationships. Assurance and counseling along with early treatment of acne vulgaris is important to reduce disease-related psychosocial sequelae and increase the efficacy of treatment. PMID:27688440

    Fractional radiofrequency microneedling is a novel radiofrequency technique that uses insulated microneedles to deliver energy to the deep dermis at the point of penetration without destruction of the epidermis. It has been used for the treatment of various dermatological conditions including wrinkles, atrophic scars and hypertrophic scars. There have been few studies evaluating the efficacy of fractional radiofrequency microneedling in the treatment of acne, and none measuring objective parameters like the number of inflammatory and non-inflammatory acne lesions or sebum excretion levels. The safety and efficacy of fractional radiofrequency microneedling in the treatment of acne vulgaris was investigated. In a prospective clinical trial, 25 patients with moderate to severe acne were treated with fractional radiofrequency microneedling. The procedure was carried out three times at 1-month intervals. Acne lesion count, subjective satisfaction score, sebum excretion level and adverse effects were assessed at baseline and at 4, 8 and 12 weeks after the first treatment as well as 4, 8 and 12 weeks after the last treatment. Number of acne lesions (inflammatory and non-inflammatory) decreased. Sebum excretion and subjective satisfaction were more favorable at every time point compared with the baseline values (P < 0.05). Inflammatory lesions responded better than non-inflammatory lesions (P < 0.05). Adverse effects such as pinpoint bleeding, pain and erythema were noted, but were transient and not severe enough to stop treatment. Fractional radiofrequency microneedling is a safe and effective treatment for acne vulgaris.

    Dapsone 7.5% gel (Aczone(®)) is indicated for the once-daily topical treatment of acne vulgaris in patients aged ≥12 years. Dapsone is a sulfone antibacterial with anti-inflammatory actions, which are thought to be largely responsible for its efficacy in treating acne vulgaris. In two phase III trials of 12 weeks' duration in patients aged ≥12 years with moderate acne vulgaris, once-daily dapsone 7.5% gel reduced acne severity (as per the Global Acne Assessment Score) and lesion counts versus vehicle. The benefits of dapsone 7.5% gel over vehicle were seen as early as week 2 for inflammatory lesion counts, and from week 4 or 8 for other outcomes. Dapsone 7.5% gel was well tolerated, with a low incidence of treatment-related adverse events, with the majority of adverse events being administration-site related and mild or moderate in severity. Thus, dapsone 7.5% gel is an effective and well tolerated option for the topical treatment of acne vulgaris in patients aged ≥12 years, with the convenience of once-daily application.

    The near-infrared (NIR) laser radiation due to its high penetration depth is widely used in phototherapy. In application to skin appendages a high selectivity of laser treatment is needed to prevent light action on surrounding tissues. Indocyanine Green (ICG) dye may provide a high selectivity of treatment due to effective ICG uploading by a target and its narrow band of considerable absorption just at the wavelength of the NIR diode laser. The goal of this study is to demonstrate the efficacy of the NIR diode laser phototherapy in combination with topical application of ICG suggested for soft and thermal treatment of acne vulgaris. 28 volunteers with facile or back-located acne were enrolled. Skin sites of subjects were stained by ICG and irradiated by NIR laser-diode light (803 or 809 nm). Untreated, only stained and only light irradiated skin areas served as controls. For soft acne treatment, the low-intensity (803 nm, 10 - 50 mW/cm2, 5-10 min) or the medium-intensity (809 nm, 150 - 190 mW/cm2, 15 min) protocols were used. The single and multiple (up to 8-9) treatments were provided. The individual acne lesions were photothermally treated at 18 W/cm2 (803 nm, 0.5 sec) without skin surface cooling or at 200 W/cm2 (809 nm, 0.5 sec) with cooling. The results of the observations during 1-2 months after the completion of the treatment have shown that only in the case of the multiple-wise treatment a combined action of ICG and NIR irradiation reduces inflammation and improves skin state during a month without any side effects. At high power densities (up to 200 W/cm2) ICG stained acne inflammatory elements were destructed for light exposures of 0.5 sec. Based on the concept that hair follicle, especially sebaceous gland, can be intensively and selectively stained by ICG due to dye diffusion through pilosebaceous canal and its fast uptake by living microorganisms, by vital keratinocytes of epithelium of the canal and sebaceous duct, and by rapidly proliferating

    Lipids are important constituents of the human epidermis. Either free and organized into broad lipid bilayers in the intercorneocytes spaces, or covalently bound to the corneocyte envelope, they play a crucial role in permeability barrier function and are major contributors to cutaneous anti-microbial defense. Free sphingoid bases are a recent addition to this family of active lipids, which emerged from studies of breakdown products from ceramides. Phytosphingosine (PS) is a lipid occurring naturally in the stratum corneum, both in its free form and as a part of the major fraction of ceramides. The biotechnological production of PS patented by Degussa yields to PS with the correct configuration present in the skin. So, application of a PS containing formulation leads to its integration into the natural lipid structures of the skin. In acne, different pathogenetic factors contribute to the inflammation process, defect in keratinization, increased sebaceous gland activity and increased colonization of Propionibacterium acnes. The results of in vitro and in vivo studies confirm the previous reports on strong anti-microbial effectiveness of skin-identical PS produced by Degussa in vitro and in vivo. In addition, PS shows excellent clinical results in the context of skin care in acne, based on both anti-inflammatory and anti-microbial activity. These results demonstrate the potential of PS to enhance or complement existing acne therapies acting as an active cosmetic ingredient.

    Acne vulgaris, commonly termed acne, is an extremely common disease. It can be found in nearly all teenagers to some degree as well as in women in their 30s. Regardless of severity, acne often has a greater psychologic effect than cutaneous effect. Indeed, most patients overestimate the severity of their disease, while most physicians underestimate its impact on their patients. Studies have shown that people with severe acne as teens are less employable as adults and that self-esteem is low. When combined with other adolescent tensions, acne can be a difficult disease to treat. Rosacea, which usually starts in the late 20s, may affect the eyes as well as the skin. This article describes the pathogenesis of acne and rosacea and treatment approaches the primary care physician can use.

    In brief: The treatment of acne is basically the same for athletes and nonathletes. However, certain aspects of sports can affect acne adversely, and in some cases treating athletes may require a cautious approach. The best treatments are topical tretinoin for comedonal acne, benzoyl peroxide or topical antibiotics and tretinoin for comedonal and mild pustular acne, and a combination of oral antibiotics and long-term benzoyl peroxide or topical antibiotics (with the eventual aim of stopping the oral antibiotics in three to five months) for moderate to severe pustular acne. For severe cystic/nodular acne, highdose oral antibiotics and intralesional steroid injections or oral isotretinoin should be considered.

    Introduction Acne vulgaris is a pilosebaceous gland disease that usually affects people from puberty to young adulthood. It is seen especially on the face, neck, trunk and arms. Its severity differs from patient to patient and its pathogenesis is multifactorial. The main pathogenic factors of acne are high sebaceous gland secretion, follicular hyperproliferation, high androgen effects, propionibacterium acnes colonization and inflammation. Diet is always thought a probable reason for acne and many studies are done about acne and diet. Aim To determine the effect of insulin resistance in severe acne vulgaris. Material and methods Two hundred and forty-three acne vulgaris patients and 156 healthy controls were enrolled into the study. The blood levels of insulin and glucose were measured. Homeostasis Model Assessment (HOMA) Index was calculated. The values were compared with the control group. Results All of the patients were in the severe acne group according to their scores on the global acne scoring scale. While fasting blood glucose levels were not different between the groups (p > 0.05, 82.91 ±9.76 vs. 80.26 ±8.33), the fasting insulin levels were significantly higher in the patient group than in the control group (p < 0.001, 14.01 ±11.94 vs. 9.12 ±3.53). Additionally, there was a highly significant difference between the patient and control groups in terms of HOMA values (p < 0.001, 2.87 ±2.56 vs. 1.63 ±0.65). Conclusions These results suggest that insulin resistance may have a role in the pathogenesis of acne. PMID:26366152

    A total of 120 consecutive patients with pustular and cystic acne vulgaris were selected for study. Patients were assigned a placebo and a tetracycline medication in a random method. Of the 53 patients who were given tetracycline, 45 showed some response, which was fair in 19 and excellent in 26. Of the 55 patients who received placebo, 24 showed no response while 31 showed some improvement. No side effects were reported. The difference in response between the two groups is statistically significant. It is concluded that administration of 250 mg. tetracycline four times daily, even for periods as short as two weeks, enhances the likelihood of improvement of cystic or pustular acne vulgaris.

    Acne vulgaris is a common skin condition associated with multiple factors. Although mostly presenting alone, it can likewise present with features of hyperandrogenism and hormonal discrepancies. Of note, hormonal therapies are indicated in severe, resistant-to-treatment cases and in those with monthly flare-ups and when standard therapeutic options are inappropriate. This article serves as an update to hormonal pathogenesis of acne, discusses the basics of endocrinal evaluation for patients with suspected hormonal acne, and provides an overview of the current hormonal treatment options in women.

    Acne vulgaris is one of the common dermatological diseases and its pathogenesis is multifactorial. In this study, we aim to determine the effects of oxidative stress in acne vulgaris. Forty-three consecutive acne patients and 46 controls were enrolled. The parameters of oxidative stress such as catalase (CAT), glucose-6-phosphate dehydrogenase (G6PD), superoxide dismutase (SOD), and malondialdehyde (MDA) in the venous blood of cases were measured spectrophotometrically. The values compared with control group, the relation between the severity and distribution of acne, and the correlation of each enzyme level were researched. CAT and G6PD levels in patients were found to be statistically decreased, and SOD and MDA levels were found to be statistically increased (P < .001). However, any statistical difference and correlation could not be found between the severity and distribution of lesions and the mean levels of enzymes. In addition, we found that each enzyme is correlated with one another. Our findings show that oxidative stress exists in the acne patients. It will be useful to apply at least one antioxidant featured drug along with the combined acne treatment. PMID:16489259

    Acne Vulgaris is one of the most common skin disorders which dermatologists have to treat. It mainly affect adolescent, though may present at any age. In recent years, due to better understanding of the pathogenesis of acne, new therapeutic modalities and various permutation and combinations have been designed. In topical agents; benzoyl peroxide, antibiotics, retinoids, etc are the mainstay of treatment; can be given in combinations. While systemic therapy includes oral antibiotics, hormonal therapy, and isotretinoin, depending upon the need of patients it has to be selected. Physical treatment in the form of lesion removal, photo-therapy is also helpful in few of them. Since various old and new topical and systemic agents are available to treat acne, it sometime confuse treating dermatologist. To overcome this, panel of physicians and researchers worked together as a global alliance and task force to improve outcomes in acne treatment. They have tried to give consensus recommendation for the treatment of acne. Successful management of acne needs careful selection of anti-acne agents according to clinical presentation and individual patient needs. PMID:21572783

    Objective: Comparatively little attention has been paid to the role of free radical oxidation in acne vulgaris. Here, using the traditional abnormalities cited for acne, the authors address the role of free radical oxidation throughout the pathogenesis by detailing the chemistry that may contribute to clinical changes. To probe the effects of free radical oxidation and test an antioxidant, they conducted a preliminary study of topically applied vitamin E. Methods: Seventeen patients with mild-to-moderate acne vulgaris were evaluated over an eight-week period in two private dermatology practices in this open-label study. All patients enrolled were on the same baseline regimen of salicylic acid and benzoyl peroxide. This regimen was then supplemented with topical vitamin E in sunflower seed oil. Results: At the end of the eight-week period, all patients demonstrated clinical improvement, as indicated by a reduction in the number of lesions and global mean difference. A statistically significant reduction was noted as early as Week 2. Enrolled patients also expressed a positive experience due to good tolerability and easy application. Conclusion: Although the exact pathogenesis of acne vulgaris remains unknown, the presence of excessive reactive oxygen species can be implicated in each of the major abnormalities involved. This presence, along with the positive results of the authors’ preliminary study, demonstrates the need for more exploration on the use of topical antioxidants in limiting free radical oxidation in the acne model. This paper is designed to stimulate academic discussion regarding a new way of thinking about the disease state of acne. PMID:26962389

    Dermcidin (DCD), an antimicrobial peptide with a broad spectrum of activity against bacteria such as Propionibacterum acnes, is expressed constitutively in sweat in the absence of stimulation due to injury or inflammation. The aim of this study was to determine the relationship between DCD expression and acne vulgaris associated with P. acnes. The antimicrobial activity of recombinant full-length DCD (50 μg/ml) was 97% against Escherichia coli and 100% against Staphylococcus aureus. Antimicrobial activity against P. acnes ranged from 68% at 50 μg/ml DCD to 83% at 270 μg/ml DCD. DCD concentration in sweat from patients with acne vulgaris (median 9.8 μg/ml, range 6.9-95.3 μg/ml) was significantly lower than in healthy subjects (median 136.7 μg/ml, range 45.4-201.6 μg/ml) (p = 0.001). DCD demonstrated concentration-dependent, but partial, microbicidal activity against P. acnes. These results suggest that reduced DCD concentration in sweat in patients with inflammatory acne may permit proliferation of P. acnes in pilosebaceous units, resulting in progression of inflammatory acne.

    Until recently, with the exception of oral isotretinoin for the treatment of severe recalcitrant nodular acne, systemic therapy for acne vulgaris and rosacea has been based on anecdotal support, clinical experience, and small clinical trials. Tetracycline derivatives are the predominant systemic agents that have been used for both disease states, prescribed in dose ranges that produce antibiotic activity. Anti-inflammatory dose doxycycline, a controlled-release (CR) 40-mg capsule formulation of doxycycline that is devoid of antibiotic activity when administered once daily, was US Food and Drug Administration (FDA)-approved for the treatment of inflammatory lesions (papules and pustules) of rosacea, based on large-scale phase 3 pivotal trials and long-term microbiologic and safety data. Also, an extended-release (ER) tablet formulation of minocycline was approved by the FDA for the treatment of inflammatory lesions of moderate to severe acne vulgaris in patients 12 years and older based on large-scale phase 3 clinical trials that evaluated efficacy and safety, dose-response analysis, and long-term data. This article discusses the studies and clinical applications related to the use of these agents.

    Acne vulgaris is a common dermatosis affecting 80% of the population. To date, different treatments have been used to manage this condition. Antibacterials and retinoids are currently the mainstay of treatment for acne, but their success rate varies. Phototherapy is emerging as an alternative option to treat acne vulgaris. Studies examining the role of different wavelengths and methods of light treatment have shown that phototherapy with visible light, specifically blue light, has a marked effect on inflammatory acne lesions and seems sufficient for the treatment of acne. In addition, the combination of blue-red light radiation seems to be superior to blue light alone, with minimal adverse effects. Photodynamic therapy has also been used, even in nodular and cystic acne, and had excellent therapeutic outcomes, although with significant adverse effects. Recently, low energy pulsed dye laser therapy has been used, and seems to be a promising alternative that would allow the simultaneous treatment of active acne and acne scarring. Further studies are needed to clarify the role of phototherapy as a monotherapy or an adjuvant treatment in the current management of acne vulgaris.

    Although acne is not an infectious disease, oral antibiotics have remained a mainstay of treatment over the last 40 years. The anti-inflammatory properties of oral antibiotics, particularly the tetracyclines, are efficacious in treating inflammatory acne lesions. Common prescribing practices in Dermatology exert significant selection pressure on bacteria, contributing to the development of antibiotic resistance. Antibiotic use for acne not only promotes resistance in Propionibacterium acnes, but also affects other host bacteria with pathogenic potential. This review will summarize the commonly used treatments for acne vulgaris, and how they should be combined as rational treatment. The indications for using oral antibiotics in acne will be highlighted. Strategies described in the literature to conserve the utility of oral antibiotics will be summarized. These include limiting the duration of antibiotic therapy, concomitant use of a topical non-antibiotic agent, use of subantimicrobial dose doxycycline, and the introduction of topical dapsone.

    The near-infrared (NIR) laser radiation due to its high penetration depth is widely used in phototherapy and photothermolysis. In application to skin appendages a high selectivity of laser treatment is needed to prevent light action on surrounding tissues. Indocyanine Green (ICG) dye may provide a high selectivity of treatment due to effective ICG uploading by a target and its narrow band of considerable absorption just at the wavelength of the NIR diode laser. The goal of this study is to demonstrate the efficacy of the NIR diode laser photothermolysis in combination with topical application of ICG suggested for treatment of acne vulgaris. Two volunteers with back-located acne were enrolled. Skin sites of subjects were stained by ICG and irradiated by NIR laser-diode light (803 or 809 nm). The individual acne lesions were photothermally treated at 18 W/cm2 (803 nm, 0.5 sec) without skin surface cooling or at 200 W/cm2 (809 nm, 0.5 sec) with cooling. The results of the observations during a month after the treatment have shown that ICG stained acne inflammatory elements were destructed for light exposures of 0.5 sec.

    The relationship between diet and acne is highly controversial. Several studies during the last decade have led dermatologists to reflect on a potential link between diet and acne. This article presents the latest findings on a potential impact that diet can have on pathogenesis of acne vulgaris. The association between diet and acne can no longer be dismissed. Compelling evidence shows that high glycemic load diets may exacerbate acne. Dairy ingestion appears to be weakly associated with acne and the roles of omega-3 fatty acids, dietary fiber, antioxidants, vitamin A, zinc and iodine remain to be elucidated. The question of what the impact of diet is on the course of acne vulgaris still remains unclear. PMID:27279815

    In acne vulgaris, antimicrobial peptides (AMPs) could play a dual role; i.e., protective by acting against Propionibacterium acnes, pro-inflammatory by acting as signalling molecules. The cutaneous expression of 15 different AMPs was investigated in acne patients; furthermore, the impact of isotretinoin therapy on AMP expression was analysed in skin biopsies from 13 patients with acne vulgaris taken before, during and after a 6-month treatment cycle with isotretinoin using quantitative real-time polymerase chain reaction. Cutaneous expression of the AMPs cathelicidin, human β-defensin-2 (HBD-2), lactoferrin, lysozyme, psoriasin (S100A7), koebnerisin (S100A15), and RNase 7 was upregulated in untreated acne vulgaris, whereas α-defensin-1 (HNP-1) was downregulated compared to controls. While relative expression levels of cathelicidin, HBD-2, lactoferrin, psoriasin (S100A7), and koebnerisin (S100A15) decreased during isotretinoin treatment, only those of cathelicidin and koebnerisin returned to normal after 6 months of isotretinoin therapy. The increased expression of lysozyme and RNase 7 remained unaffected by isotretinoin treatment. The levels of granulysin, RANTES (CCL5), perforin, CXCL9, substance P, chromogranin B, and dermcidin were not regulated in untreated acne patients and isotretinoin had no effect on these AMPs. In conclusion, the expression of various AMPs is altered in acne vulgaris. Isotretinoin therapy normalizes the cutaneous production of distinct AMPs while the expression of others is still increased in healing acne. Considering the antimicrobial and pro-inflammatory role of AMPs, these molecules could serve as specific targets for acne therapy and maintenance of clinical remission.

    Acne vulgaris is a common skin disorder that can affect individuals from childhood to adulthood, most often occurring in the teenage years. Acne can have a significant physical, emotional, and social impact on an individual. Many different treatment options are available for the treatment of acne vulgaris. Commonly used topical treatments include benzoyl peroxide, antibiotics, sulfur and sodium sulfacetamide, azelaic acid, and retinoids. Systemic treatment is frequently used and includes the use of systemic antibiotics, oral contraceptives, antiandrogens, and retinoids. Other treatment modalities exist such as the use of superficial chemical peels as well as using laser and light devices for the treatment of acne. With the multitude of treatment options and the rapidly expanding newer technologies available to clinicians, it is important to review and be aware of the current literature and studies regarding the treatment of acne vulgaris.

    Acne vulgaris may be improved by dietary factors that increase insulin sensitivity. We hypothesized that a low-glycemic index diet would improve facial acne severity and insulin sensitivity. Fifty-eight adolescent males (mean age ± standard deviation 16.5 ± 1.0 y and body mass index 23.1 ± 3.5 kg/m(2)) were alternately allocated to high or low glycemic index diets. Severity of inflammatory lesions on the face, insulin sensitivity (homeostasis modeling assessment of insulin resistance), androgens and insulin-like growth factor-1 and its binding proteins were assessed at baseline and at eight weeks, a period corresponding to the school term. Forty-three subjects (n = 23 low glycemic index and n = 20 high glycemic index) completed the study. Diets differed significantly in glycemic index (mean ± standard error of the mean, low glycemic index 51 ± 1 vs. high glycemic index 61 ± 2, p = 0.0002), but not in macronutrient distribution or fiber content. Facial acne improved on both diets (low glycemic index -26 ± 6%, p = 0.0004 and high glycemic index -16 ± 7%, p = 0.01), but differences between diets did not reach significance. Change in insulin sensitivity was not different between diets (low glycemic index 0.2 ± 0.1 and high glycemic index 0.1 ± 0.1, p = 0.60) and did not correlate with change in acne severity (Pearson correlation r = -0.196, p = 0.244). Longer time frames, greater reductions in glycemic load or/and weight loss may be necessary to detect improvements in acne among adolescent boys.

    Polyphenols are antioxidant molecules found in many foods including nuts, fruits, vegetables, chocolate, wine, and tea. Polyphenols have antimicrobial, anti-inflammatory, and antineoplastic properties. Recent studies suggest that tea polyphenols may be used for reducing sebum production in the skin and for treatment of acne vulgaris. This review examines the evidence for use of topically and orally ingested tea polyphenols against sebum production and for acne treatment and prevention. The PubMed database was searched for studies on tea polyphenols, sebum secretion, and acne vulgaris. Of the 59 studies found, eight met the inclusion criteria. Two studies evaluated tea polyphenol effects on sebum production; six studies examined tea polyphenol effects on acne vulgaris. Seven studies evaluated topical tea polyphenols; one study examined systemic tea polyphenols. None of the studies evaluated both topical and systemic tea polyphenols. Tea polyphenol sources included green tea (six studies) and tea, type not specified (two studies). Overall, there is some evidence that tea polyphenols in topical formulation may be beneficial in reducing sebum secretion and in treatment of acne. Research studies of high quality and with large sample sizes are needed to assess the efficacy of tea polyphenols in topical and oral prevention of acne vulgaris and lipid synthesis by the sebaceous glands.

    There is no topical antiacne medication that acts against all four of the major pathophysiologic features of acne: hyperkeratinization, sebum production, bacterial proliferation, and inflammation. Topical azelaic acid cream helps both to normalize keratinization and to reduce the proliferation of Propionibacterium acnes, and has proven to be effective against both noninflammatory and inflammatory lesions. The results of a recent study now demonstrate that its efficacy can be enhanced, and patient ratings of overall impression improved, when it is used in combination with other topical medications such as benzoyl peroxide 4% gel, clindamycin 1% gel, tretinoin 0.025% cream, and erythromycin 3%/benzoyl peroxide 5% gel. Furthermore, another study has shown that azelaic acid plus benzoyl peroxide achieves greater efficacy and higher patient ratings of convenience than monotherapy with erythromycin-benzoyl peroxide gel.

    Acne vulgaris is one of the most common chronic inflammatory skin disorders among adolescents and young adults. It is associated with substantial morbidity and, rarely, with mortality. The exact worldwide incidence and prevalence are currently unknown. Current challenges involve improving understanding of the underlying pathophysiology of acne vulgaris and developing a practical treatment consensus. Expert panel discussions were held in 2013 and 2014 among a group of scientists and clinicians from the Omani and United Arab Emirate Dermatology Societies to ascertain the current optimal management of acne vulgaris, identify clinically relevant end-points and construct suitable methodology for future clinical trial designs.

    Importance Acne vulgaris is the most common skin condition affecting late adolescents across the globe. Although prior studies have evaluated epidemiologic patterns of acne vulgaris in various ethnicities and regions, adequate understanding of the worldwide burden of the disease associated with patients in their late adolescence (15–19-year olds) remains lacking. Objective To assess the global burden of the disease associated with acne vulgaris for late adolescents (15–19-year olds) and provide an overview of the epidemiology, pathophysiology, and treatment options for acne in this population. Design Database summary study. Setting Global Burden of Disease Study 2010 database. Participants Global Burden of Disease regions comprised countries with prevalence of acne vulgaris between the ages of 15 and 19 years. Main outcomes and measures Geographic region-level disability-adjusted life year rates (per 100,000 persons) associated with acne vulgaris in years 1990 through 2010. Median percentage change in disability-adjusted life year rates was estimated for each region across the specified study period. Conclusion and relevance Acne vulgaris-associated disease burden exhibits global distribution and has continued to grow in prevalence over time within this population. This continued growth suggests an unmet dermatologic need worldwide for this disorder and potential opportunities for improved access and delivery of dermatologic care. Our analysis of the literature reveals numerous opportunities for enhanced patient care. To that end, we highlight some of the effective and promising treatments currently available and address important factors, such as sex, nationality, genetics, pathophysiology, and diet, as they relate to acne vulgaris in late adolescence.

    Intense pulsed light (IPL) has been used for years in treatment of acne vulgaris. However, quantitative evaluation of histopathological changes after its use as a sole therapy was poorly investigated. Accordingly, this study aims to objectively evaluate inflammatory infiltrate and sebaceous glands in acne vulgaris after IPL. Twenty-four patients of acne were treated with six IPL sessions. Clinical evaluation was done at 2 weeks after last session by counting acne lesions. Patient satisfaction using Cardiff Acne Disability Index (CADI) was recorded at baseline, 2 weeks and 3 months after IPL. Using histopathological and computerized morphometric analysis, quantitative evaluation of inflammatory infiltrate and measurement of surface area of sebaceous glands were performed for skin biopsies at baseline and 2 weeks after last session. After IPL, there was significant reduction of all acne lesions especially inflammatory variety with significant decrease of CADI score at 2 weeks and 3 months after IPL (p < .05). Microscopically, there was significant decrease in density of inflammatory infiltrate and surface area of sebaceous glands (p < .05). So, IPL is fairly effective therapy in acne vulgaris especially inflammatory variety. The results suggest that IPL could improve acne lesions through targeting both inflammation and sebaceous glands.

    Acne vulgaris is the most common cutaneous disorder affecting adolescents and young adults. Some studies have reported an association between serum zinc levels and acne vulgaris. We aimed to evaluate the serum zinc level in patients with acne vulgaris and compare it with healthy controls. One hundred patients with acne vulgaris and 100 healthy controls were referred to our clinic. Acne severity was classified according to Global Acne Grading System (GAGS). Atomic absorption spectrophotometry was used to measure serum zinc levels. Mean serum level of zinc in acne patients and controls was 81.31 ± 17.63 μg/dl and 82.63 ± 17.49 μg/dl, respectively. Although the mean serum zinc level was lower in acne group, it was not statistically significant (P = 0.598). There was a correlation between serum zinc levels with severity and type of acne lesions. The results of our study suggest that zinc levels may be related to the severity and type of acne lesions in patients with acne vulgaris. Relative decrease of serum zinc level in acne patients suggests a role for zinc in the pathogenesis of acne vulgaris.

    Sebum production is the key factor in the pathophysiology of acne. Studies in sebocyte and human sebaceous gland biology indicate that agonists of peroxisome proliferator-activated receptors (PPARs) alter sebaceous lipid production. Our objective was to detect the expression of PPARβ/δ in acne lesions and find its contribution to disease pathogenesis. Twenty five acne vulgaris patients (14 males, 11 females) were included. In addition, 12 healthy volunteers (6 males, 6 females) served as controls. Punch biopsies (3mm) were taken from lesional skin of all patients, non-lesional skin in 12 patients, and from the healthy controls. The biopsies were estimated quantitatively for the level of PPARβ/δ mRNA using reverse transcriptase-polymerase chain (RT-PCR) technique. PPARβ/δ mRNA levels were significantly higher in patients than controls (p=0.00) and in patients' lesional than non-lesional skin (p=0.00). No significant difference however, was found between inflammatory and non-inflammatory lesions. Age and disease duration had no influence on mean PPAR mRNA levels in lesional skin. PPARβ/δ is over expressed-in inflammatory and non-inflammatory acne vulgaris and may well be considered as a candidate target in future acne therapy. However, elucidation of its functional role is recommended.

    BACKGROUND Acne vulgaris has high prevalence, disturbing quality of life during adolescence. OBJECTIVES To measure dissastifaction and acne in 18-year-old male individuals and its associated factors. METHODS A questionnaire was applied by trained interviewers to all boys during selection for the military service. Dissatisfaction and acne was evaluated using a self-administered face scale. Facial, prestrernal and dorsal acne were evaluated separately. RESULTS A total of 2,200 adolescents, aged 18 years, were interviewed. Among these, 1,678 had acne on the face and 974 (54.05%) showed some degree of dissatisfaction. Regarding the impact of acne located on the chest, 326 out of 686 adolescents (47.52%) reported dissatisfaction. For acne located on the back, 568 out of 1,103 affected individuals (51.50%) showed dissatisfaction. Facial / dorsal acne and dissatisfaction were statistically associated with lower income, lower education levels and with non-whites. Presternal acne and dissatisfaction were statistically asssociated with lower income and lower education levels. CONCLUSION This population-based study found a high prevalence of acne on the face, back and chest, with high rates of dissatisfaction. PMID:25054743

    Acne vulgaris is a pervasive inflammatory disorder of the skin, with multiple etiologies and treatment options. Although first-line therapies exist, it is often the case that a patient will present with an underlying disorder that prohibits the use of most currently accepted treatment modalities. We present a patient with severe acne vulgaris and a history of retinitis pigmentosa who was treated with 595 nanometer pulsed dye laser therapy, in conjunction with therapeutic alternatives to first-line acne medications. Our patient exhibited a significant and sustained improvement with the combined use of 595 nanometer pulsed dye laser, Yaz (drospirenone-ethinyl estradiol), dapsone, topical metronidazole, sodium-sulfacetamide wash, and topical azelaic acid. The positive results in this case, suggest that this combined treatment modality may serve as an example of a safe and effective treatment alternative in the management of acne vulgaris complicated by medical co-morbidities that contraindicate the use of most first-line treatment options.

    Acne vulgaris is a common dermatological disorder, one that is frequently associated with depression, anxiety and other psychological sequelae. In recent years there has been an increasing focus on the extent to which oxidative stress is involved in the pathophysiology of acne. Emerging studies have shown that patients with acne are under increased cutaneous and systemic oxidative stress. Indeed, there are indications that lipid peroxidation itself is a match that lights an inflammatory cascade in acne. The notion that lipid peroxidation is a 'starter gun' in acne is not a new one; here we review the nearly 50-year-old lipid peroxidation theory and provide a historical perspective to the contemporary investigations and clinical implications.In addition, we present a novel hypothesis in which lipid peroxidation may be priming an increased susceptibility to co-morbid depression and anxiety in those with acne. The emerging research on the systemic burden of oxidative stress in acne sheds further light on the brain-skin axis. The recent findings also suggest potential avenues of approach for the treatment of acne via specific nutrients, dietary modifications, oral and topical interventions.

    Acne is a common skin condition with sebum overproduction, hyperkeratosis, Propionibacterium acnes (P. acnes) and Staphylococcus aureus, and inflammation. Punica granatum (pomegranate) is well-known for its anti-inflammatory effects; however, few studies have discussed the anti-acne effects of pomegranate. In this study, we found that pomegranate extract (PG-E) significantly reduced P. acnes-induced edema in Wistar rat ears. Therefore, an evaluation platform using multiple pathogenic mechanisms of acne was established to explore the anti-acne effects of pomegranate. Results showed that PG-E inhibited bacterial growth and lipase activity. Through a bioguided-fractionation-isolation system, four hydrolysable tannins, punicalagin (1), punicalin (2), strictinin A (3), and granatin B (4), were isolated. Compounds 1 and 2 had greater anti-bacterial activities and anti-testosterone-induced HaCaT proliferative effects than the others. Compounds 1, 3, and 4 displayed lipase inhibitory effects. Compound 4 decreased cyclooxygenase-2 expression and downregulated prostaglandin E2 production in heat-killed P. acnes-treated RAW 246.7 cells. In conclusion, PG-E is abundant in hydrolysable tannins that display multiple anti-acne capacities, including anti-bacterial, anti-lipase, anti-keratinocyte proliferation, and anti-inflammatory actions. Hence, PG-E has great potential in the application of anti-acne and skin-care products, and punicalagin (1), the most effective component in PG-E, can be employed as a quality control marker.

    Androgenic stimulation of sebaceous glands is necessary for development of acne. If hyperandrogenaemia were a major determinant of acne in women, the frequency of other clinical markers of androgenicity should increase with acne severity. To investigate this, 268 female subjects (aged 12-44 years) were studied. Subjects were divided into groups on the basis of acne severity: physiological, moderate, and severe. With exclusion of women taking oral contraceptives or anti-androgen therapy, subjects in each group were similar with respect to age at menarche and incidence of menstrual irregularity of amenorrhoea. Reports of excessive body hair, and clinical hirsutes on examination were few and there were no significant differences between acne severity groups. No correlation was observed between acne and hirsutes grades in all subjects (rank correlation coefficient = 0.096). Mild male pattern androgenic alopecia occurred in similar proportions of subjects in the three groups. Female pattern androgenic alopecia was observed in only two subjects. We have shown no correlation between acne severity and clinical markers of androgenicity in women. This suggests that in most cases factors other than hyperandrogenaemia are necessary for the development of acne.

  20. The rationale for using a topical retinoid for inflammatory acne.

    PubMed

    Millikan, Larry E

    2003-01-01

    Both comedogenesis and the development of inflammatory lesions in acne vulgaris appear to be related to genetic as well as immune processes. The key regulatory cytokine, interleukin-1alpha, has recently been documented as playing a major role in both the hypercornification and the orchestration of immune factors, ultimately resulting in noninflammatory and inflammatory lesions. Topical retinoids, such as tretinoin, and topical retinoid analogs, such as adapalene and tazarotene, help normalize the abnormal follicular keratinocyte desquamation - a key pathophysiologic factor in comedogenesis. This normalization also helps mitigate against the development of a propitious microenvironment for Propionibacterium acnes. Preclinical data suggest that topical retinoids and retinoid analogs may also have direct anti-inflammatory effects. A wealth of clinical data confirms that topical retinoids and retinoid analogs significantly reduce inflammatory lesions. Comparative clinical trials also demonstrate that adapalene has the best cutaneous tolerability profile of all these agents. Optimal therapy for inflammatory acne would involve the use of topical retinoids or retinoid analogs combined with oral or topical antibacterials.

    Acne is a common disorder affecting the pilosebaceous unit. Despite many advances in the treatments of acne vulgaris the best option is still controversial as the pathogenesis of acne is rather complex, necessitating various combination therapies. The objective of this study is to compare the clinical efficacy of intense pulsed light therapy (IPL) versus benzoyl peroxide 5% for the treatment of inflammatory acne. Fifty patients of both sexes, (15 males and 35 females) aged (18-27 years), with mild-to-severe acne and Fitzpatrick skin phototype IV were enrolled in this study. The patients were equally divided into two groups. The first group was treated by benzoyl peroxide while the second group was treated by IPL. For both therapies, patients experienced a significant reduction in the mean of the inflammatory lesion counts over the treatment period. Comparing the effects of both therapies, BP produced better results than IPL. The difference in the results was statistically significant at the midpoint of the study. However, this difference was insignificant at the end of study. Treatment with both benzoyl peroxide and IPL resulted in considerable improvement of the acne after 5 weeks of treatment. Comparing the effects of both therapies, BP produced better results than IPL. The difference in the results was statistically significant at the midpoint of the study. However, this difference was insignificant at the end of study.

    INTRODUCTION: Although acne vulgaris is common in adolescents, information on their understanding of acne is minimal. OBJECTIVES: To evaluate the perceptions and beliefs of Saudi youth on acne. MATERIALS AND METHODS: Three hundred twenty-nine male students (aged 13–22 years) from 6 secondary schools in the Eastern Saudi Arabia completed a self-reported questionnaire on knowledge, causation, exacerbating and relieving factors of acne. Data were analyzed by SPSS version 15.0. Results of subjects with acne, a family history of acne, and parents' educational levels were compared. Differences between the analyzed groups were assessed by a Chi-square test; p ≤ 0.05 was considered statistically significant. RESULTS: Over half (58.9%) of the participants considered acne a transient condition not requiring therapy. Only 13.1% knew that the proper treatment of acne could take a long time, even several years. Over half (52%) thought acne can be treated from the first or after few visits to the doctor. Popular sources of information were television/radio (47.7%), friends (45.6%), and the internet (38%). Only 23.4% indicated school as a source of knowledge. Reported causal factors included scratching (88.5%) and squeezing (82.1%) of pimples, poor hygiene (83.9%), poor dietary habits (71.5%), and stress (54.1%). Ameliorating factors included frequent washing of the face (52.9%), exercise (41.1%), sunbathing (24.1%), and drinking of mineral water (21%). The correlations of these facts are discussed. CONCLUSION: Results of this study point out that misconceptions of acne are widespread among Saudi youth. A health education program is needed to improve the understanding of the condition.

    Acne is an easily recognizable abnormality which may cause some adverse psychosocial consequences. We aimed to determine the social phobia frequency, social anxiety level, and disease related disability in a group of acne vulgaris patients. One-hundred and forty acne vulgaris patients and 98 healthy control subjects were included in the study. Acne severity was determined by the Global Acne Grading System (GAGS). A psychiatrist interviewed each participant and the Liebowitz Social Anxiety Scale (LSAS) was administered to all participants, who also completed the Hospital Anxiety and Depression Scale (HADS) and Sheehan Disability Scale (SDS). Social phobia was diagnosed in 45.7% of acne vulgaris patients and in 18.4% of control subjects. Acne vulgaris patients demonstrated higher performance avoidance and total avoidance scores in LSAS than controls. Acne vulgaris patients without social phobia had higher scores in HADS and LSAS than the acne vulgaris patients with social phobia. They were more disabled in their occupational, social, and familial lives. Social phobia diagnosis predicted disability at work, whereas education level predicted the disability in family life of acne vulgaris patients. Social phobia seems to be a common psychiatric comorbidity which may give rise to some additional disability among acne vulgaris patients.

    An inevitable condition for the pharmacist is a basic knowledge of dermatological changes which are prominent in acne and solar impairment of the skin to be able to recommend in a qualified manner an effective and safe treatment to the patient. However, sufferers of the more serious forms of acne should always be referred to their general practitioner, or preferentially a dermatologist. Acne vulgaris is an androgen-induced disorder, but three major mechanisms for the development of the disease have been identified: hypertrophy of the sebaceous gland, hyperkatosis of the follicular epithelium, and proliferation of microbial flora, particularly Propionibacterium acnes. The basis of all lesions is the microcomedone which is developed into the ripe comedone. Inflammatory lesions are thought to be due to proliferation of P. acnes. In the selfmedication of common acne, benzoyl peroxide, which in a 5-10% lotion exerts antimicrobial and keratolytic properties, proved to be useful. Patients appreciate a lot its instant effect which is visible after just one day of treatment. Salicylic acid is another effective drug, which, when used on the long-term basis, has comedolytic properties; it reduces the number of microcomedones and counteracts plugging of the follicles. In addition, in healthy young women who take oral contraception, a triphasic combined oral preparations of contraceptives with newer progestins, notably with norgestimmate, which is practically free of androgenic effects, are recommended with advantage for the treatment of moderate acne vulgaris without any adverse effects. Solar impairment of the skin, the so-called solar ageing, is clinically indistinguishable from biological ageing. Changes connected with solar impairment appear mostly in the dermis, where solar elastosis develops, the skin gets drier and wrinkle formation appears. For the treatment, hydroxy acids are recommended, namely salicylic acid, which is very effective, because in combination with a

    The therapeutic value of various ultraviolet treatments was assessed in patients with moderately severe papulopustular acne. The results did not verify the common belief that ultraviolet radiation is highly beneficial. In no instance was the comedo count appreciably reduced. Modest improvement was observed with sunburn rays (UV-B) and slightly more with the combination of long ultraviolet radiation (UV-A) and UV-B. UV-A alone had the least effect. Photosensitization with coal tar and UV-A greatly aggravated acne and was notably comedogenic. Photosensitization with methoxsalen (8-methoxypsoralen) applied topically was neither harmful nor helpful.

    Immune reconstitution disease (IRD) has been widely reported following the commencement of antiretrovirals. We report a case series from a cohort of HIV-1-infected patients of whom four developed acne vulgaris and one developed acne rosacea after the initiation of antiretroviral therapy. Acne vulgaris, as part of IRD, has been reported only once in the literature, whereas acne rosacea has not, to our knowledge, previously been described. This serves as a reminder not to overlook dermatological manifestations of disease in patients with HIV infection after starting antiretrovirals.

    It is known that effectiveness of acne treatment increases when the lesions are detected earlier, before they could progress into mature wound-like lesions, which lead to scarring and discoloration. However, little is known about the evolution of acne from early signs until after the lesion heals. In this work we computationally characterize the evolution of inflammatory acne lesions, based on analyzing cross-polarized images that document acne-prone facial skin over time. Taking skin images over time, and being able to follow skin features in these images present serious challenges, due to change in the appearance of skin, difficulty in repositioning the subject, involuntary movement such as breathing. A computational technique for automatic detection of lesions by separating the background normal skin from the acne lesions, based on fitting Gaussian distributions to the intensity histograms, is presented. In order to track and quantify the evolution of lesions, in terms of the degree of progress or regress, we designed a study to capture facial skin images from an acne-prone young individual, followed over the course of 3 different time points. Based on the behavior of the lesions between two consecutive time points, the automatically detected lesions are classified in four categories: new lesions, resolved lesions (i.e. lesions that disappear completely), lesions that are progressing, and lesions that are regressing (i.e. lesions in the process of healing). The classification our methods achieve correlates well with visual inspection of a trained human grader.

    Acne vulgaris is an extremely common skin condition. It often leads to negative psychological consequences. Photodynamic therapy (PDT) using intense pulsed light has been introduced for effective treatment of acne. The objective was to study the effect of PDT in truncal acne vulgaris using liposomal methylene blue (LMB) versus IPL alone. Thirty-five patients with varying degrees of acne were treated with topical 0.1 % LMB hydrogel applied on the randomly selected one side of the back, and after 60 min the entire back was exposed to IPL. The procedure was done once weekly for three sessions and patients were re-evaluated 1 month after the third session by two independent dermatologists. Acne severity was graded using the Burton scale. Patient satisfaction using Cardiff Acne Disability Index (CADI) was recorded before and after treatment. On LMB-pretreated side, inflammatory acne lesion counts were significantly decreased by 56.40 % compared with 34.06 % on IPL alone. Marked improvement was seen on LMB-pretreated side in 11.5 % of patients compared with 2.8 % on IPL alone. There was a correlation between CADI score and overall improvement. Our study concluded that LMB-IPL is more effective than IPL alone, safe with tolerable pain in the treatment of acne vulgaris on the back.

    Androgenic stimulation of sebaceous glands is an important factor in the development of acne. We examined 36 females (aged 14-34 years), selected because none had received oral contraceptives, anti-androgen therapy, or systemic antibiotics during the previous year, or isotretinoin therapy, prior to their participation in the study. Subjects were divided into groups on the basis of acne severity, as follows: physiological, mild and moderate. Only two patients had polycystic ovaries on ultrasound examination. Seven patients had irregular menses; none had evidence of hirsutism. We found that the severity of acne, based on the acne grade, was highly correlated with the inflammatory lesion count, and less correlated with the sebum excretion rate. Either acne grade or inflammatory lesion count could be related to some of the five androgenic hormone determinants; free testosterone (TESTOS), delta 4 androstenedione (DELTA 4), sex hormone binding globulin (SHBG), dehydroepiandrostenedione sulphate (DHEAS) and dihydrotestosterone (DHT). Multiple linear regression analysis determined the best model for predicting ACNE scores as involving DELTA 4 and DHEAS (positive effects), and SHBG (negative effect), P < 0.005, R2 = 0.36). In none of the patients were the levels of DHEAS or SHBG outside the normal range. The findings in the two patients with polycystic ovaries did not differ significantly from those in the remainder of the patients.

    This review summarizes clinically important findings from 3 systematic reviews, 1 updated guideline and a selection from the 62 randomized controlled trials (RCTs) published between February 2007 and January 2009 on the topic of acne vulgaris. Low glycaemic-load diets might reduce acne severity but this remains unproven. Written patient information leaflets have not been surpassed by other communication methods. New combination topical treatments have not shown convincing advantages over current combination products such as clindamycin/benzoyl peroxide. Topical dapsone is superior to placebo but has yet to be compared with standard topical treatments. Long-term topical tretinoin to prevent nonmelanoma skin cancer in elderly men was associated with higher all-cause mortality, but there is currently no evidence of increased mortality for topical retinoid use when treating acne. All oral tetracyclines have similar efficacy, yet minocycline is the most costly. Oral isotretinoin monotherapy remains the gold-standard treatment for severe acne. Flutamide plus the oral contraceptive pill is beneficial for acne associated with polycystic ovary syndrome. Photodynamic therapy, phototherapy and laser therapy cannot be recommended universally for acne until minimal postinflammatory pigmentation and longer-term benefit can be shown, especially with current high costs. Development of non-antibiotic therapies is preferable to minimize the risk of community antibiotic resistance. Future trials should use active comparators at optimum doses and avoid noninferiority comparisons unless appropriately powered. Trials need to shift from using multiple, unvalidated outcome measures to including patient-reported and quality-of-life outcomes, and all trials should be registered on a public clinical-trials database.

    As the pathophysiology of acne is complex and multifactorial, the continued influx of new basic science and clinical information requires careful analysis before drawing conclusions about what truly contributes to the development and progression of this chronic disease. Our objective is to review the latest evidence and highlight a number of important perspectives on the pathophysiology of acne. An improved understanding of acne pathogenesis should lead to more rational therapy and a better understanding of the role of P acnes opens new perspectives for the development of new treatments and management. Further research may be directed at targeting receptors, adhesion molecules, cytokines, chemokines or other pro-inflammatory targets implicated in the activation of immune detection and response (i.e., toll-like receptors [TLRs], protease-activated receptors [PARs]) that appear to contribute to the pathophysiology of acne. Therapeutic options that reduce the need for topical and/or oral antibiotic therapy for acne are welcome as bacterial resistance to antibiotics is a clinically relevant concern both in the United States and globally.

    Objective: To evaluate the clinical characteristics and epidermal barrier function of papulopustular rosacea by comparing with acne vulgaris. Methods: Four hundred and sixty-three papulopustular rosacea patients and four hundred and twelve acne vulgaris patients were selected for the study in Xiangya Hospital of Central South University from March 2015 to May 2016. They were analyzed for major facial lesions, self-conscious symptoms and epidermal barrier function. Results: Erythema, burning, dryness and itching presented in papulopustular rosacea patients were significantly higher than that in acne vulgaris patients (P<0.001). The clinical scores of erythema, burning, dryness and itching in papulopustular rosacea patients were significantly higher than those in acne vulgaris patients (P<0.001). The water content of the stratum cornuem and skin surface lipid level were both significantly lower in papulopustular rosacea patients than that of the acne vulgaris patients (P<0.001) and healthy subjects (P<0.001); Water content of the stratum cornuem and skin surface lipid level were higher in acne vulgaris patients in comparison with that of healthy subjects (P>0.05, P<0.001; respectively). Transepidermal water loss was significantly higher in papulopustular rosacea patients than that of acne vulgaris patients and healthy subjects (P<0.001); transepidermal water loss was lower in skin of acne vulgaris patients than that of healthy subjects (P<0.001). Conclusion: Erythema, burning, dryness and itching are the characteristics of papulopustular rosacea, which makes it different from acne vulgaris. The epidermal barrier function was damaged in papulopustular rosacea patients while not impaired in that of acne vulgaris patients. PMID:28083023

    The cutaneous inflammation associated with acne vulgaris is caused by the anaerobic bacterium Propionibacterium acnes through activation of the innate immune system in the skin. Current standard treatments for acne have limitations that include adverse effects and poor efficacy in many patients, making development of a more effective therapy highly desirable. In the present study, we demonstrate the protective effects of a novel customized α-helical cationic peptide, P5, against P. acnes-induced inflammatory responses in vitro and in vivo. Application of P5 significantly reduced expression of two inflammatory cytokines IL-8 and TNF-α in P. acnes-treated primary human keratinocytes, where P5 appeared to act in part by binding to bacterial lipoteichoic acid, thereby suppressing TLR2-to-NF-κB signaling. In addition, in a mouse model of acne vulgaris, P5 exerted both anti-inflammatory and antimicrobial effects against P. acnes, but exerted no cytotoxic effects against skin cells. These results demonstrate that P5, and perhaps other cationic antimicrobial peptides, offer the unique ability to reduce numbers P. acnes cells in the skin and to inhibit the inflammation they trigger. This suggests these peptides could potentially be used to effectively treat acne without adversely affecting the skin. PMID:26197393

    Interleukin-8 (IL-8) is a well-known inflammatory chemokine and suggested to be involved in the development of acne vulgaris. This study investigates IL-8 plasma levels in acne patients and healthy controls and the molecular basis for the regulation of the IL-8 gene in a Pakistani population. Patients with acne vulgaris (n = 264) and healthy individuals (n = 264) were enrolled in this investigation. Plasma IL-8 levels were determined by enzyme-linked immunosorbent assay (ELISA). The genotyping for IL-8 gene was performed by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). Our data showed a statistically significant increase in IL-8 levels from acne patients compared with healthy subjects (154.2 ± 52.1 pg/mL in patients vs. 101.6 ± 33.5 pg/mL in controls, p<0.0001). The IL-8-251T>A (rs4073) polymorphism was significantly higher in patients with acne compared with the control group (p=0.013). There was a significant difference between the T and A alleles from acne cases and controls (odds ratio OR=1.6,95 % CI= 1.16-2.19, p=0.003). Logistic-regression analysis showed that the increased IL-8 levels, and the IL-8-251T>A polymorphism were significantly associated with acne. Our data suggest that the elevated IL-8 levels and the IL-8-251T>A polymorphism may be associated with acne vulgaris in the study population.

    Isotretinoin is the strongest, most effective oral treatment for patients with severe acne vulgaris, with remission rates of 89% and higher. Because of its potency, isotretinoin causes many adverse reactions. This article reviews common and severe adverse reactions to isotretinoin and how providers can best manage these reactions. Because of inconclusive research on the correlation between isotretinoin and depression and irritable bowel syndrome, providers should ask patients about symptoms monthly. Prescribing micronized isotretinoin and starting at the lowest dose with gradual upward titration also can help reduce the incidence of adverse reactions.

    Acne vulgaris is the most common skin disease, causing significant psychosocial problems such as anxiety and depression similar to a chronic illness for those afflicted. Currently, obtainable agents for acne treatment have limited use. Thus, development of novel agents to treat this disease is a high medical need. The anaerobic bacterium Propionibacterium acnes has been implicated in the inflammatory phase of acne vulgaris by activating pro-inflammatory mediators such as the interleukin-8 (IL-8) via the NF-κB and MAPK pathways. Talaromyces wortmannii is an endophytic fungus, which is known to produce high bioactive natural compounds. We hypothesize that compound C but also the crude extract from T. wortmannii may possess both antibacterial activity especially against P. acnes and also anti-inflammatory properties by inhibiting TNF-α-induced ICAM-1 expression and P. acnes-induced IL-8 release. Treatment of keratinocytes (HaCaT) with P. acnes significantly increased NF-κB and activator protein-1 (AP-1) activation, as well as IL-8 release. Compound C inhibited P. acnes-mediated activation of NF-κB and AP-1 by inhibiting IκB degradation and the phosphorylation of ERK and JNK MAP kinases, and IL-8 release in a dose-dependent manner. Based on these results, compound C has effective antimicrobial activity against P. acnes and anti-inflammatory activity, and we suggest that this substance or the crude extract are alternative treatments for antibiotic/anti-inflammatory therapy for acne vulgaris.

    Background Dermatological diseases, among which acne vulgaris, have psychological impact on the affected generating feelings of guilt, shame and social isolation. Objectives To compare quality of life, self-esteem and other psychosocial variables amongst adolescents with and without acne vulgaris, and between levels of severity. Methods Cross-sectional observational study in a sample of 355 high school students from the city of João Pessoa. Data collection was performed with questionnaires and clinical-dermatological evaluation. The primary variables were the incidence of AV; quality of life, set by the Children's Dermatology Quality of Life Index and Dermatology Quality of Life Index; and self-esteem, measured by the Rosenberg Self-Esteem Scale. For calculation of statistical tests, we used the SPSS 20.0 software, considering p=0.05. Results The sample, with an average age of 16, showed 89.3% prevalence of acne vulgaris. The most prevalent psychosocial issue was "afraid that acne will never cease", present in 58% of affected youth. The median score of Quality of Life in Children's Dermatology Index was different amongst students with and without acne vulgaris (p=0.003), as well as the Quality of Life in Dermatology (p=0.038) scores, so that students with acne vulgaris have worse QoL. There was a correlation between the severity of acne vulgaris and worse quality of life. Self-esteem was not significantly associated with the occurrence or severity of acne vulgaris. Conclusions acne vulgaris assumes significance in view of its high prevalence and the effect on quality of life of adolescents, more severe at the more pronounced stages of disease (p<0.001). The psychosocial impact of acne vulgaris should be valued in the management of patients with this condition. PMID:26560206

    Acne vulgaris is the most common dermatologic disorder seen in American black patients (ie, African Americans and African Caribbeans, Fitzgerald skin types IV through VI). Despite its prevalence, there is a lack of data on the effects of treatments, such as the use of topical retinoids and retinoid analogs, in this patient population. Adapalene is a topical retinoid analog that has demonstrated efficacy in the reduction of noninflammatory and inflammatory lesions, along with excellent cutaneous tolerability. Most clinical studies of this agent have involved predominantly white patient populations. This meta-analysis of 5 randomized US and European studies was designed to evaluate the efficacy and safety of adapalene in black versus white patients. The percentage reduction in the number of inflammatory lesions was significantly greater among black patients compared with white patients (P=.012). The percentage reductions in total inflammatory and noninflammatory lesion counts were similar in the 2 groups (P>.3). There were significantly less erythema and scaling in black patients compared with white patients (P<.001 and P=.026 for worst scores for erythema and scaling, respectively). Although the incidence of dryness was similar in both groups, a smaller percentage of black than white patients had moderate or severe scores for dryness (7% vs 18%, respectively). In summary, adapalene appears to be a viable treatment for black patients with acne vulgaris.

    Until now, etiology of acne vulgaris is still uncertain. Although clinicians usually deny the association between Demodex infestation and acne vulgaris, it has been proved in some clinical practices. To confirm the association between Demodex infestation and acne vulgaris, a meta-analysis was conducted. Predefined selection criteria were applied to search all published papers that analyzed the association between Demodex infestation and acne vulgaris (January 1950 to August 2011) in ISI Web of Knowledge, MEDLINE, and China National Knowledge Infrastructure (CNKI) databases. A meta-analysis was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs) based on fixed effects models or random effects models. We enrolled the 60 Chinese and 3 English papers in this meta-analysis, which covered Turkey and 25 different provinces/municipalities in China and 42130 participants including students and residents, aged from 1 to 78 years. The pooled OR in random effects models is 2.80 (95% CI, 2.34-3.36). Stability is robust according to sensitivity analysis. The fail-safe number is 18477, suggesting that at least 18477 articles with negative conclusions would be needed to reverse the conclusion that acne vulgaris was related to Demodex infestation. So the effect of publication bias was insignificant and could be ignored. It was concluded that acne vulgaris is associated with Demodex infestation. This indicates that when regular treatments for acne vulgaris are ineffective, examination of Demodex mites and necessary acaricidal therapies should be considered.

    The delayed-type immune reactivities of 39 patients suffering from moderate to severe papulopustular or nodulo-cystic forms of Acne vulgaris were compared with healthy acne-free controls. In vivo reactivity was assessed by skin testing with four common recall antigens. In vitro the afferent arm of the immune system was assayed by antigen and mitogen simulated lymphocyte transformation and the efferent arm by granulocyte random migration and by granulocyte responsiveness to a standard migration inhibitory lymphokine preparation. Spontaneous lymphocyte transformations were also evaluated. In acne patients the skin test reactivities were in general only slightly decreased. Their lymphocytes showed relatively normal responses to mitogen stimulation, but antigen responsiveness was significantly diminished. Furthermore the patients' lymphocytes showed increased spontaneous transformation. All these changes correlated, to some extent, with the severity of the disease. The granulocytes of acne patients showed increased random migration, of borderline significance, but the granulocyte responses to the lymphokine preparation were completely normal. The results suggest that immunologic abnormalities are mild and probably secondary to the inflammatory process.

    The treatment of acne vulgaris poses a challenge to the dermatologist, and the disease causes emotional anxiety for the patient. The treatment of acne vulgaris may be well-suited to home-use applications, where sufferers may be too embarrassed to seek medical treatment. This randomized controlled study is designed to quantify the effectiveness of using a blue light device in a therapy combined with proprietary creams, in the investigation of a self-treatment regimen. A total of 41 adults with mild-to-moderate facial inflammatory acne were recruited. The subjects were randomly assigned to combination blue light therapy (n = 26) or control (n = 15). Photography was used for qualitative assessment of lesion counts, at weeks 1, 2, 4, 8, and 12. All subjects in the treatment cohort achieved a reduction in their inflammatory lesion counts after 12 weeks. The mean inflammatory lesion counts reduced by 50.02% in the treatment cohort, and increased by 2.45% in the control cohort. The reduction in inflammatory lesions was typically observable at week-3, and maximal between weeks 8 and 12. The treatment is free of pain and side-effects. The blue light device offers a valuable alternative to antibiotics and potentially irritating topical treatments. Blue light phototherapy, using a narrow-band LED light source, appears to be a safe and effective additional therapy for mild to moderate acne.

    Background and Aims: Acne vulgaris affects about 85% of adolescents, often extending into adulthood. Psychosocial impact of acne on health-related quality of life (QoL) has been identified, but it remains under-evaluated, especially in Indian patients. This study was aimed to assess the impact of acne and its sequelae on the QoL. Materials and Methods: This was a hospital-based, prospective, cross-sectional study done between June and November 2014 on 114 consenting patients above 15 years of age with acne vulgaris. Acne vulgaris and its sequelae were graded, and QoL was assessed by using Dermatology Life Quality Index (DLQI) questionnaire. Results: Most cases (64%) were between 15 and 20 years. Females (57%) outnumbered males. Facial lesions (61.4%) and grade II acne were most common. Mean DLQI score was 7.22. DLQI scores were statistically influenced by the age of the patient, duration and grade of acne, acne scar, and postacne hyperpigmentation. Conclusion: This study showed significant impairment of QoL in acne patients. Assurance and counseling along with early treatment of acne vulgaris are important to reduce disease-related psychosocial sequelae and increase the efficacy of treatment. PMID:27057015

    Acne vulgaris is the most common skin disorder affecting millions of people worldwide and inflammation resulting from the immune response targeting Propionibacterium acnes plays a significant role in its pathogenesis. In this study, we have demonstrated that P. acnes is a potent inducer of Th17 and Th1, but not Th2 responses in human PBMCs. P. acnes stimulated expression of key Th17-related genes, including IL-17A, RORα, RORc, IL-17RA and IL-17RC, and triggered IL-17 secretion from CD4+, but not CD8+ T cells. Supernatants from P. acnes-stimulated PBMCs were sufficient to promote the differentiation of naïve CD4+CD45RA T cells into Th17 cells. Furthermore, we found that the combination of IL-1β, IL-6 and TGF-β neutralizing antibodies completely inhibited P. acnes-induced IL-17 production. Importantly, we showed that IL-17-expressing cells were present in skin biopsies from acne patients but not from normal donors. Finally, vitamin A (all-trans retinoic acid) and vitamin D (1,25-dihydroxyvitamin D3) inhibited P. acnes-induced Th17 differentiation. Together, our data demonstrate that IL-17 is induced by P. acnes and expressed in acne lesions and that both vitamin A and vitamin D could be effective tools to modulate Th17-mediated diseases such as acne.

    Sera from 23 patients with acne vulgaris of varying degrees and sera from 15 patients with skin diseases other than acne were tested for antibody levels to Staphylococcus epidermidis by use of bacterial agglutination and agar-gel immunodiffusion. Antibody levels to S epidermidis varied from 0 to 1:160 in both the patients with acne and in the control groups. There was no correlation between the antibody level to S epidermidis and the degree of acne. In a previous investigation it was found that antibody levels to Corynebacterium acnes are significantly increased in serum from patients with papulopustular and cystic acne. Both S epidermidis and C acnes can frequently be isolated from lesions in acne. The fact that antibody levels are increased to C acnes but not to S epidermidis may indicate that the mere presence of an organism in the acne lesion is not sufficient stimulation for antibody formation. The increase of antibody to C acnes which was demonstrated previously in patients with severe acne vulgaris may therefore reflect a direct involvement of the organism in the acne process.

    Oral spironolactone has been used for over two decades in the dermatological setting. Although it is not generally considered a primary option in the management of female patients with acne vulgaris, the increase in office visits by post-teenage women with acne vulgaris has recently placed a spotlight on the use of this agent in this subgroup of patients. This article reviews the literature focusing on the use of oral spironolactone in this subset of women with acne vulgaris, including discussions of the recommended starting dose, expected response time, adjustments in therapy, potential adverse effects, and patient monitoring.

    Acne vulgaris is a very common skin disorder. Previous studies have indicated that genetic background factors play key roles in the onset of acne. Our previous investigation implicated several genes in the androgen metabolism pathway with acne vulgaris in the Han Chinese population. Thus, we further investigated genes and genetic variants that play important roles in this pathway for their relationship with the pathology of acne. In this study, a total of 610 subjects, including 403 acne patients and 207 healthy controls, were genotyped for 15 single-nucleotide polymorphisms in HSD3B1 and HSD17B3 genes. This study shows that rs6428829 in HSD3B1 was associated with acne vulgaris in Han patients from Southwest China, even after adjusting for age and sex. The GG genotype was associated with an increased risk of acne vulgaris (p < 0.05) and G allele carriers were associated with an increased risk of acne vulgaris (p < 0.05). In addition, the haplotype AAT in HSD3B1 significantly increased the risk of acne vulgaris in the case-control study (p < 0.05). Furthermore, for another gene in this pathway, HSD17B3, the haplotype H8 was significantly associated with an increased risk of acne vulgaris. Based on these analyses, our study indicates that the cutaneous androgen metabolism-regulated genes HSD3B1 and HSD17B3 increase the susceptibility to acne vulgaris in Han Chinese from Southwest China.

    Acne vulgaris is the most common skin disease treated by physicians. Current topical and oral treatments may have short- and long-term negative consequences. Since radiofrequency (RF) energy has been shown to reduce sebum production and 410-nm blue light has been shown to kill Propionibacterium acnes (P. acnes) cells, these modalities in combination should be a highly effective treatment of acne vulgaris with little or no downtime or risk. This case report describes the efficacy and safety of RF energy (Accent, Alma Lasers Inc, Buffalo Grove, IL) and blue light (BLU-U, Dusa Pharmaceuticals, Inc, Wilmington, MA) used in combination to treat grade 4 cystic acne and acne scars in an Asian woman of skin type IV. The results were considered excellent by both investigators and the patient, with improvement in the skin tone as an added cosmetic benefit.

    Introduction Isotretinoin has been successfully used for the treatment of acne vulgaris. Aim To investigate the effects of isotretinoin on body mass index (BMI), to determine whether isotretinoin causes any changes in serum adiponectin, leptin, and ghrelin levels in acne vulgaris patients, and to correlate variables. Material and methods Thirty-two patients were included in this study. Oral isotretinoin was begun at a dose of 0.5–0.6 mg/kg and raised to 0.6–0.75 mg/kg. Pretreatment and posttreatment third-month BMI and adiponectin, leptin, and ghrelin serum levels were measured. Results The pre- and posttreatment BMI values were not significantly different. In addition, serum adiponectin and leptin levels were significantly increased following isotretinoin therapy while serum ghrelin levels were not different. Conclusions Isotretinoin may exert its anti-inflammatory activity by increasing leptin and adiponectin levels. PMID:27605902

    Background: Acne vulgaris of the face is a common dermatological disease with a significant impact on the quality of life, psychosocial development as well as self-esteem of the patients. Nano emulsion gel formulations are said to have various advantages over the conventional formulations. Aim: The present study was conducted to assess the comparative efficacy and safety of a nano-emulsion gel formulation of clindamycin with its conventional formulation in the treatment of acne vulgaris of the face. Materials and Methods: This prospective, active controlled, multicentric, phase IV clinical trial evaluated the treatment of patients with acne vulgaris of the face by a nano emulsion gel formulation or conventional gel formulation of clindamycin (as phosphate) 1% locally applied twice daily for 12 weeks as per random allocation. Acne lesion counts (inflammatory, non-inflammatory and total) and severity grading were carried out on the monthly scheduled visits along with tolerability assessments. Results: A total of 200 patients (97 males) were included for Intention to Treat analysis in the trial with 100 patients in each group. Reductions in total (69.3 vs. 51.9%; p<0.001), inflammatory (73.4 vs. 60.6%; p<0.005) and non inflammatory (65.1 vs. 43.7%; p<0.001) acne lesions were reported to be significantly greater with the nano-emulsion gel formulation as compared to the conventional gel formulation. Significantly more reduction in the mean acne severity score was noticeable with the nano-emulsion gel formulation (-1.6 ± 0.9 vs. -1.0 ± 0.8; p<0.001) than the comparator. A trend towards better safety profile of the nano emulsion gel formulation was reported. Conclusion: In the treatment of acne vulgaris of the face, clindamycin nano emulsion gel formulation appears to be more effective than the conventional gel formulation and is also well tolerated.

    This study aimed to determine circulating levels of polyunsaturated fatty acids (PUFAs), secretory phospholipase A2 (sPLA2), lipoprotein lipase (LPL) and measure circulating protein levels of angiopoietin-like protein 3 (ANGPTL3), ANGPTL4, cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2) in patients with acne vulgaris. Serum from 21 control subjects and 31 acne vulgaris patients were evaluated for levels of arachidonic acid (AA, C20:4n- 6), dihomo-gamma-linolenic acid (DGLA, C20:3n-6), eicosapentaenoic acid (EPA, C20:5n-3) and docosahexaenoic acid (DHA, C22:6n-3). PUFA levels were determined by an optimized multiple reaction monitoring (MRM) method using ultra fast-liquid chromatography (UFLC) coupled with tandem mass spectrometry (MS/MS). Lipid profile, routine biochemical and hormone parameters were assayed by standard kit methods Serum EPA levels were significantly decreased while AA/EPA and DGLA/EPA ratio were significantly increased in acne vulgaris patients compared to controls. Serum levels of AA, DGLA and DHA showed no significant difference while activity of sPLA2 and LPL were significantly increased in acne vulgaris compared to controls. Results of this study reveal the presence of a proinflammatory state in acne vulgaris as shown by significantly decreased serum EPA levels and increased activity of sPLA2, AA/EPA and DGLA/EPA ratio. Increased LPL activity in the serum of acne vulgaris patients can be protective through its anti-dyslipidemic actions. This is the first study reporting altered EPA levels and increased sPLA2 activity in acne vulgaris and supports the use of omega-3 fatty acids as adjuvant treatment for acne patients.

  14. Cosmeceuticals based on Rhealba(®) Oat plantlet extract for the treatment of acne vulgaris.

    PubMed

    Fabbrocini, G; Saint Aroman, M

    2014-12-01

    Recent evidence suggests that acne vulgaris begins as an inflammation in and around the sebaceous gland and alterations in the lipid content of sebum, which drive hyperproliferation and increased desquamation of keratinocytes within sebaceous follicles. This prevents sebum drainage, causing the formation of microcomedones, which spontaneously regress or become acne lesions when the pilosebaceous unit is further blocked by the accumulation of corneocytes. These conditions are favourable for the proliferation of Propionibacterium acnes, which further aggravates acne by enhancing abnormal desquamation, sebum production and inflammation. Also, skin fragility due to inflammation or irritation by anti-comedogenic agents can worsen the situation. Rhealba(®) Oat plantlet extract (Pierre Fabre Dermo Cosmetique) soothes and restores fragile skin in acne by reducing inflammation and inhibits bacterial adhesion of Propionibacterium acnes. Cosmeceuticals combining Rhealba(®) Oat plantlet extract and hydro-compensating actives, which are available with or without anti-comedogenic hydroxy acids, provide a balanced, multifaceted approach for acne patients.

    Acne vulgaris is a common dermatological disorder with a multifactorial pathogenesis. Oxidative status has been implicated in the pathogenesis of several skin diseases, including acne. This study was aimed to investigate the levels of oxidative stress biomarkers in acne vulgaris patients with varying severities. The study involved 156 patients with acne and 46 healthy human controls. Based on clinical examination, patients were grouped into 3 subgroups as follows: mild, moderate, and severe acne. Oxidative stress was examined by measuring plasma levels of catalase (CAT), superoxide dismutase (SOD), total antioxidant capacity (TAC), and malondialdehyde (MDA). Plasma levels of MDA in acne patients were significantly higher as compared with that of the controls, whereas activities of the antioxidant enzymes SOD and CAT were lower. Moreover, TAC was also low in acne patients as compared with that of the controls. Higher MDA levels in the severe acne subgroup as compared with that of the mild and moderate subgroups were also observed. Furthermore, in the severe acne subgroup, a significant negative correlation was observed between MDA and CAT levels. The data suggests that oxidative stress plays a key role in acne progress and may be employed as a biomarker index to assess the disease's activity and to monitor its treatment.

    Context: Acne vulgaris affects about 85% of teenagers and may continue to adulthood. There are about two million visits to physicians per year for teenagers and the direct cost of acne treatment in the US exceeds $1 billion per year. Evidence Acquisition: A wide variety of treatment regimens exist for acne vulgaris including benzoil peroxide, retinoids, isotretinoids, keratolytic soaps, alpha hydroxy acids, azelaic acid, salicilic acid as well as hormonal, anti-androgen or antiseborrheic treatments. However, none of these methods is free of side effects and their exact role in therapy is not clear. In this paper apart from presenting the possible causes of acne vulgaris and its available drugs, recently published papers about medicinal plants used in the treatment of acne vulgaris were reviewed. Results: Consumption of alternative and complementary medicine, including medicinal plants, is increasing and is common amongst patients affected by acne and infectious skin diseases. Medicinal plants have a long history of use and have been shown to possess low side effects. These plants are a reliable source for preparation of new drugs. Conclusions: Many plants seem to have inhibitory effects on the growth of bacteria, fungi and viruses in vitro. However, there are a few clinical evidences about the effectiveness and safety of these plants in the treatment of acne and other skin infections. PMID:26862380

    The possible relationship between plasma androgenic activity and acne vulgaris was investigated. Plasma testosterone and sex hormone binding globulin (SHBG) levels were determined in healthy girls during different stages of puberty, in healthy adult women and in women with acne vulgaris. Testosterone increase during puberty, whereas SHBG decreased during the early stages before it increased and stabilized plasma concentrations of testosterone and SHBG. Women with severe acne vulgaris had testosterone levels in the same range but the SHBG levels were significantly lower than those of healthy women and women with mild acne. These results show a high androgenic activity in the intermediate stages of puberty, when acne vulgaris is a common complaint and an increased androgenic activity in adult women with severe acne vulgaris.

    Ozenoxacin, a novel non-fluorinated topical quinolone, was assessed for in vitro antimicrobial activity against clinical isolates of propionibacteria and staphylococci according to the broth microdilution method recommended by the Clinical and Laboratory Standards Institute. The isolates used in this study were collected from Japanese patients with acne vulgaris during a period from 2012 to 2013. The MIC90s of ozenoxacin against Propionibacterium acnes (n=266), Propionibacterium granulosum (n=10), Staphylococcus aureus (n=23), Staphylococcus epidermidis (n=229) and other coagulase-negative staphylococci (n=82) were ≤0.06, ≤0.06, ≤0.06, 0.125 and ≤0.06 µg ml-1, respectively. The antimicrobial activity of ozenoxacin against the clinical isolates of propionibacteria and staphylococci was greater than that of five reference antimicrobial agents which have been used for the treatment of acne vulgaris. The MICs of ozenoxacin were correlated with those of nadifloxacin in P. acnes and S. epidermidis isolates. However, the MICs of ozenoxacin were 0.25-0.5 µg ml-1 and 0.5-8 µg ml-1 against nadifloxacin-resistant P. acnes (MIC: ≥8 µg ml-1; n=8) and S. epidermidis (MIC: ≥64 µg ml-1; n=10), respectively. These results indicated the potent antimicrobial activity against P. acnes and S. epidermidis isolates resistant to nadifloxacin. Topical ozenoxacin could represent an alternative therapeutic drug for acne vulgaris based on its potent antimicrobial activity against the isolates of propionibacteria and staphylococci from acne patients.

    Acne vulgaris may be effectively treated with combination oral contraceptive pills (COCs) in women. COCs may be useful in any woman with acne in the absence of known contraindications. When prescribing a COC to a woman who also desires contraception, the risks of the COC are compared with the risks associated with pregnancy. When prescribing a COC to a woman who does not desire contraception, the risks of the COC must be weighed against the risks associated with acne. COCs may take 3 cycles of use to show an effect in acne lesion count reductions.

    Acne vulgaris alters the normal skin physiology, impairing stratum corneum and transepidermal water loss. A male's normal skin physiologic state is different than a female's and may have implications when choosing treatment when the skin is altered in a disease state. Transepidermal water loss, pH, and sebum production are different between the sexes. Several underlying conditions present in male acne patients at several ages that may require a more in-depth evaluation. As knowledge of the pathogenesis of acne expands, the differences in skin physiology between the sexes may alter the manner in which male patients with acne medications are approached.

    Allergen Inc has launched Aczone, a topical gel formulation of the antibacterial, anti-inflammatory agent dapsone, for the potential treatment of acne vulgaris. Oral dapsone has demonstrated efficacy in acne, but was associated with severe side effects such as anemia, which was particularly serious in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency. Aczone was developed to overcome this limitation, and is formulated using solvent-microparticle technology for improved absorption and action and for fewer side effects. In a phase I clinical trial, systemic exposure to dapsone was 126-fold lower following treatment with Aczone compared with oral dapsone. Aczone significantly reduced lesion counts in patients with acne in phase III trials, and was particularly effective in reducing inflammatory lesions. In a phase IV trial, Aczone was safely applied to patients with G6PD deficiency without inducing anemia. Phase IV trials in patients with acne were ongoing at the time of publication to assess safety and to compare Aczone monotherapy with combinations of Aczone and other anti-acne therapeutics. At the time of publication, Allergen was also developing Aczone for the treatment of rosacea; the drug was undergoing phase II trials for this indication. Aczone appears to be a novel promising anti-acne therapeutic option, particularly for patients with inflammatory acne.

    Background We believe that instances of neuroticism and common psychiatric disorders are higher in adults with acne vulgaris than the normal population. Objective Instances of acne in adults have been increasing in frequency in recent years. The aim of this study was to investigate personality traits and common psychiatric conditions in patients with adult acne vulgaris. Methods Patients who visited the dermatology outpatient clinic at Bozok University Medical School with a complaint of acne and who volunteered for this study were included. The Symptom Checklist 90-Revised (SCL 90-R) Global Symptom Index (GSI), somatization, depression, and anxiety subscales and the Eysenck Personality Questionnaire-Revised Short Form (EPQ-RSF) were administered to 40 patients who fulfilled the inclusion criteria before treatment. The results were compared with those of a control group. Results Of the 40 patients included in this study, 34 were female and 6 were male. The GSI and the somatization, depression, and anxiety subscales of the SCL 90-R were evaluated. Patients with adult acne had statistically significant higher scores than the control group on all of these subscales. In addition, patients with adult acne had statistically significantly higher scores on the neuroticism subscale of the EPQ-RSF. Conclusion Our results show that common psychiatric conditions are frequent in adult patients with acne. More importantly, neurotic personality characteristics are observed more frequently in these patients. These findings suggest that acne in adults is a disorder that has both medical and psychosomatic characteristics and requires a multi-disciplinary approach. PMID:25673931

  5. Management of acne vulgaris with hormonal therapies in adult female patients.

    Acne vulgaris is a very common condition affecting up of 93% of adolescents. Although rare, this disease may persist in adulthood. In adult women with acne (those older than 25 years old), this condition is particularly relevant because of the refractory to conventional therapies, which makes acne a challenge for dermatologists in this group of patients. In order to its potential risk for chronicity and the involvement of visible anatomical sites such as face and upper torso, acne has been associated with a wide spectrum of psychological and social dysfunction such as depression, anxiety, suicidal ideation, somatization, and social inhibition. In particular, adult women with acne have been shown to be adversely impacted by the effect of acne on their quality of life. For the last four decades, dermatologists have used hormonal therapies for the management of acne vulgaris in adult women, which are considered a rational choice given the severity and chronicity of this condition in this group of patients. The aim of this work is to review the hormonal drugs for management of acne.

  6. Ovulatory patterns in women with juvenile and late-onset/persistent acne vulgaris.

    The ovulatory patterns in women with acne vulgaris were evaluated in order to understand their relationship with androgenic levels. Ovulation disturbances were found in 58.3% of patients with prevalence of anovulation in the juvenile acne and of luteal insufficiency in the late-onset/persistent acne. Significant negative correlation was found between T free and P in the late-onset/persistent group (r: -0.629; p = 0.016): This may be interpreted as a rather steady endocrine status in which the raised androgenic levels, probably due to peripheral conversion, are concomitant to absent or insufficient ovulations. In the younger patients both the androgen excess and the ovulation disturbances could be due to an abnormal or delayed maturation of the hypothalamus-pituitary ovarian axis. The evaluation of the ovarian function in women with acne vulgaris may be useful to detect ovulatory disturbances in view of a possible resolution of both the problems by specific endocrine management.

    Antibiotics are commonly prescribed in dermatology practice for a variety of disorders, including acne vulgaris and rosacea. Importantly, they often are used long-term for these inflammatory dermatoses. Changes in bacterial ecology related to antibiotic prescribing have led to the decreased sensitivity of some bacterial organisms, such as Propionibacterium acnes, to antibiotics commonly prescribed by dermatologists. The potential clinical outcomes of altered bacterial sensitivities may vary among specific disease states and include decreased therapeutic response and the need to alter approaches in disease management. Additionally, changing patterns of antibiotic sensitivity and the emergence of more virulent pathogens, such as community-acquired methicillin-resistant Staphylococcus aureus, macrolide-resistant staphylococci and streptococci, and mupirocin-resistant S aureus, have led to marked changes in how clinicians use antibiotics in clinical practice. This article reviews antibiotic prescribing in dermatology practice and provides important clinical perspectives and recommendations to preserve the therapeutic value of antibiotics based on a thorough review of current literature and clinical experience.

    Topical treatments, such as adapalene and benzoyl peroxide (BPO), are popular in mild-to-moderate acne vulgaris. This study aimed to compare the efficacy, safety and tolerability of adapalene and BPO in mild acne vulgaris. In this single-center, randomized, double-blind, clinical trial, 60 patients with mild acne vulgaris received either topical adapalene 0.1% gel or topical BPO 2.5% gel on their face once daily for two months. The changes of acne lesion count (efficacy), any adverse effect (safety), and the patients' overall satisfaction (tolerability) were compared after 3 months of follow-up. In both groups the mean number of noninflammatory, inflammatory and total lesions decreased significantly from baseline (10.77±5.54, 9.73±5.09, and 20.50±7.54, respectively in adapalene group; 11.50±5.92, 8.43±5.45, and 19.93±9.01, respectively in BPO group) to the third month (1.70±1.68, 0.33±0.66, and 0.50±0.78, respectively in adapalene group; 4.23±4.14, 0.33±0.71, and 4.13±4.44, respectively in BPO group; P<0.001 for all), posttreatment. Although the mean number of inflammatory lesions was significantly lower in BPO receivers only at first month (P =0.001), the mean number of noninflammatory and total lesions was significantly lower in adapalene group at second (P = 0.04 and 0.03, respectively) and third (P =0.02 and <0.001, respectively) months, posttreatment. The adverse events were minimal and self-limited (26.7% in adapalene group, 20% in BPO group, p=0.54). The patients' overall satisfaction was good to excellent in 93.3% of adapalene receivers vs. 73.3% in BPO group (P=0.08). Both topical adapalene 0.1% and BPO 2.5% gels seem safe and effective in mild acne vulgaris, with a marginal tendency toward the former.

    A significant number of clinical practice guidelines (CPGs) about the treatment of acne vulgaris in adolescents and adults have been published worldwide. However, little is known about the quality of CPGs in this field. The aim of this study was to appraise the methodological quality of published acne vulgaris CPGs. We performed a systematic review of published CPGs on acne vulgaris therapy from July 2002 to July 2012. Three reviewers independently assessed each CPG using the AGREE II instrument. A standardized score was calculated for each of the six domains. Our search strategy identified 103 citations but just six met our inclusion criteria. Agreement among reviewers was very good: 0.981. The domains that scored better were: "scope and purpose" and "clarity and presentation". Those that scored worse were "stakeholder involvement", "rigor of development", and "applicability". The European and the Malaysian CPGs were the only recommended with no further modifications. In addition, the Mexican, Colombian and the United States guidelines were recommended with provisos, with lower scores regarding stakeholder involvement, rigor of development and applicability. Only two guidelines clearly reported outcome measures for evaluating efficacy or included quality of life outcomes. CPGs varied regarding the consideration of light/laser therapy or consideration of complementary/alternative medicines. None of them included cost considerations of drugs such as systemic isotretinoin. In conclusion, published acne vulgaris CPGs for acne therapy vary in quality with a clear need to improve their methodological rigor. This could be achieved with the adherence to current CPGs development standards.

    Propionibacterium acnes is a key pathogen involved in the progression of acne inflammation. The development of a new agent possessing antimicrobial and anti-inflammatory activity against P. acnes is therefore of interest. In this study, we investigated the inhibitory effect of rosemary (Rosmarinus officinalis) extract on P. acnes-induced inflammation in vitro and in vivo. The results showed that ethanolic rosemary extract (ERE) significantly suppressed the secretion and mRNA expression of proinflammatory cytokines, including interleukin (IL)-8, IL-1β, and tumor necrosis factor-α in P. acnes-stimulated monocytic THP-1 cells. In an in vivo mouse model, concomitant intradermal injection of ERE attenuated the P. acnes-induced ear swelling and granulomatous inflammation. Since ERE suppressed the P. acnes-induced nuclear factor kappa-B (NF-κB) activation and mRNA expression of Toll-like receptor (TLR) 2, the suppressive effect of ERE might be due, at least partially, to diminished NF-κB activation and TLR2-mediated signaling pathways. Furthermore, three major constituents of ERE, carnosol, carnosic acid, and rosmarinic acid, exerted different immumodulatory activities in vitro. In brief, rosmarinic acid significantly suppressed IL-8 production, while the other two compounds inhibited IL-1β production. Further study is needed to explore the role of bioactive compounds of rosemary in mitigation of P. acnes-induced inflammation.

    2015-01-01

    Background: Acne vulgaris (AV) is the commonest skin disorder, whereas soybean isoflavone had been proved as antiandrogen that is it can inhibit the enzyme 3ß-hydroxysteroid dehydrogenase,17ß-hydroxysteroid dehydrogenase and 5α-reductase. The purpose of this study is to prove the advantage of soybean isoflavone as antiandrogen on AV. Methods: this study is a clinical study using randomized pretest-posttest control group design. This study is a study with 40 samples randomized into 2 groups, i.e. placebo group and 160 mgs of isoflavone group, the duration is 12 weeks, conducted a double-blind manner. The dependent variabel is total of AV lesion, whereas the intermediate variable is DHT that will be examined using ELISA. Defferential test and multivariate analysis were performed on dependent, independent and intermediate variables. Results: This study found that the difference in mean of total AV lesion before treatment was not significant (p: 0.099), whereas after treatment it differed significantly (p: 0.000), with significant delta difference (p: 0.000). Difference of mean DHT level before treatment was not significant (p: 0.574), whereas after treatment it differed significantly (p: 0.000), with significant delta difference (p: 0.000). Delta of DHT (p: 0.003) (r: 0.736) had significant influence on delta of total AV lesion (P < 0.05). Conclusion: This study concludes that supplementation with 160 mgs/day of soybean isoflavone can reduce total AV lesion as a result of decreased DHT level. PMID:26413190

    Propionibacterium acnes and Staphylococcus epidermidis are normal skin inhabitants that are frequently isolated from lesions caused by acne, and these micro-organisms are considered to contribute to the inflammation of acne. In the present study, we examined the antimicrobial susceptibilities and resistance mechanisms of P. acnes and S. epidermidis isolated from patients with acne vulgaris in a university hospital in Japan from 2009 to 2010. Additionally, we analysed the relationship between the antimicrobial resistance of P. acnes and the severity of acne vulgaris. Some P. acnes strains (18.8 %; 13/69) were resistant to clindamycin. All strains had a mutation in the 23S rRNA gene, except for one strain that expressed erm(X) encoding a 23S rRNA methylase. Tetracycline-resistant P. acnes strains were found to represent 4.3 % (3/69) of the strains, and this resistance was caused by a mutation in the 16S rRNA gene. Furthermore, three strains with reduced susceptibility to nadifloxacin (MIC = 16 µg ml(-1)) were detected. When analysing the correlation between the antimicrobial resistance of P. acnes and S. epidermidis, more than 80 % of the patients who carried clindamycin-resistant P. acnes also carried clindamycin-resistant S. epidermidis. However, no epidemic strain that exhibited antimicrobial resistance was detected in the P. acnes strains when analysed by PFGE. Therefore, our results suggest that the antimicrobial resistance of P. acnes is closely related to antimicrobial therapy. Additionally, those P. acnes strains tended to be frequently found in severe acne patients rather than in mild acne patients. Consequently, the data support a relationship between using antimicrobial agents and the emergence of antimicrobial resistance.

    Increasing evidence demonstrates that commensal microorganisms in the human skin microbiome help fight pathogens and maintain homeostasis of the microbiome. However, it is unclear how these microorganisms maintain biological balance when one of them overgrows. The overgrowth of Propionibacterium acnes (P. acnes), a commensal skin bacterium, has been associated with the progression of acne vulgaris. Our results demonstrate that skin microorganisms can mediate fermentation of glycerol, which is naturally produced in skin, to enhance their inhibitory effects on P. acnes growth. The skin microorganisms, most of which have been identified as Staphylococcus epidermidis (S. epidermidis), in the microbiome of human fingerprints can ferment glycerol and create inhibition zones to repel a colony of overgrown P. acnes. Succinic acid, one of four short-chain fatty acids (SCFAs) detected in fermented media by nuclear magnetic resonance (NMR) analysis, effectively inhibits the growth of P. acnes in vitro and in vivo. Both intralesional injection and topical application of succinic acid to P. acnes-induced lesions markedly suppress the P. acnes-induced inflammation in mice. We demonstrate for the first time that bacterial members in the skin microbiome can undergo fermentation to rein in the overgrowth of P. acnes. The concept of bacterial interference between P. acnes and S. epidermidis via fermentation can be applied to develop probiotics against acne vulgaris and other skin diseases. In addition, it will open up an entirely new area of study for the biological function of the skin microbiome in promoting human health.

    Objective: Assess efficacy and safety of once-daily topical dapsone gel, 7.5% compared with vehicle for treating acne vulgaris (acne). Design: A pooled analysis of data from two identically designed, randomized, double-blind, vehicle-controlled, multicenter, 12-week clinical trials. Setting: Study sites in the United States and Canada. Participants: overall, 4,340 patients were randomized 1:1 to dapsone and vehicle. Criteria included age 12 years or older with acne diagnosis, 20 to 50 facial inflammatory lesions (papules and pustules), 30 to 100 facial noninflammatory lesions (open and closed comedones), and acne grade of 3 (moderate) on the Global Acne Assessment Score scale. Measurements: Efficacy assessments included the Global Acne Assessment Score success rate (proportion of patients with Global Acne Assessment Score of 0 [none] or 1 [minimal]) and percentage change from baseline in inflammatory and noninflammatory lesions at Week 12. Results: Global Acne Assessment Score success rates were 29.8 percent and 21.1 percent for patients who received dapsone gel, 7.5% and vehicle, respectively (p<0.001). Patients receiving dapsone gel, 7.5% had greater percentage change in lesion counts than patients receiving vehicle (inflammatory lesions: -54.6% vs. -48.1%; p<0.001; -45.1 %; noninflammatory lesions: -39.4%; p<0.001). Most adverse events were mild to moderate in severity. Mean dermal tolerability scores for stinging/burning, dryness, scaling, and erythema were similarly low with dapsone gel, 7.5% and vehicle. Conclusion: Dapsone gel, 7.5%, with a 50-percent greater dapsone concentration than twice-daily dapsone gel, 5% formulation, is applied topically once daily for acne, is effective, safe, and well-tolerated over 12 weeks, and has local tolerability similar to that of vehicle. www.clinicaltrials.gov identifiers: NCT01974141 and NCT01974323 PMID:27847545

This report examines childhood and current attention-deficit/hyperactivity disorder symptoms in a clinical sample of female adults. Ninety-one women with acne vulgaris and 53 controls were included in this study. The aforementioned symptoms were measured in participants. No significant differences were found between patients and controls in any of the measurements. Contrary to the findings of epidemiological studies, this study did not uncover a link between acne vulgaris and attention-deficit/hyperactivity disorder.

The benefits of this agent include reduction in Propionibacterium acnes (P. acnes) with decrease in inflammatory lesions, efficacy as both "leave on" and cleanser formulations and reduced emergence of antibiotic-resistant P. acnes strains. As the effect of benzoyl peroxide on P. acnes is a direct toxic effect rather than as a "true" antibiotic, resistance to benzoyl peroxide does not occur and has never been reported. Benzoyl peroxide in hydrophase base (Brevoxyl Creamy Washes and Gels) has shown significant efficacy in the treatment of acne, with lower irritancy than other benzoyl peroxide preparations. It is felt that the low irritancy of this product is related to a unique delivery vehicle containing dimethyl isosorbide, which dissolves benzoyl peroxide crystals on the skin. Clinical studies demonstrating the efficacy and safety of benzoyl peroxide in hydrophase base will be reviewed.

  19. Cyproterone acetate in the treatment of acne vulgaris in adult females.

    22 adult females with therapy-resistant acne vulgaris were treated for 12 months with Diane, a drug containing cyproterone acetate and ethinylestradiol. Treatment was withdrawn in 7 patients because of side-effects of lack of of effect. In the remaining 15 patients, the treatment had extremely promising results, from 70 to 90% improvement of the acne. In a remarkably high number of patients, the androgen production, measured by the urinary excretion of fractional 17-ketosteroids, was elevated. None of these patients had signs of endocrinological diseases, in particular no cases of hirsutism of Stein-Leventhal syndrome were found. The current concept of the course of acne is that the conversion in the skin of testosterone to dehydrotestosterone is increased. The finding of an elevated urinary excretion of androgenic substances in this group of acne patients indicates that the pathogenesis is far more complicated.

    Introduction: Pulsed dye laser (PDL) has been used to treat acne lesions and scar erythema by interrupting superficial vasculature. Salicylic acid chemical peels are employed chiefly due to their lipophilic, comedolytic, and anti-inflammatory properties. Although studies have looked at peels and laser therapy independently in acne management, we examined these treatments in combination. Our primary objective was to evaluate the safety and efficacy of concurrent use of salicylic acid peels with PDL versus salicylic acid peels alone in the treatment of moderate to severe acne vulgaris. Methods: Adult patients with moderate to severe acne were included. Subjects received a total of 3 treatments at 3-week intervals. Per randomized split-face treatment, at week 0, one half of the subject’s face was treated with PDL (595 nm) followed by whole face application of a 30% salicylic acid peel. At weeks 3 and 6, the treatments were repeated. At 0 and 9 weeks, patients were assessed with the Global Evaluation Acne (GEA) scale and Dermatology Life Quality Index (DLQI) questionnaire. Results: Nineteen subjects were enrolled, and 18 completed the study. Significant improvement in acne was seen in both the combined (laser and peel) and chemical peel alone treatment arms (P < .0005 and P = .001). Using the GEA scale score, compared to week 0, the mean difference in acne improvement at week 9 was -1.61 in the combination therapy group versus -1.11 in the peel only group. Based on the GEA scale scoring, a statistically significant greater difference in acne improvement was seen, from week 0 to week 9, in the combination treatment group compared with the peel only group (P = .003). Conclusion: While acne subjects had significant benefit from the salicylic acid peel alone, they experienced greater significant benefit from PDL treatment used in conjunction with salicylic acid peels. The adjunctive utilization of PDL to salicylic acid peel therapy can lead to better outcomes in acne

    Background: Conventional topical tretinoin formulation is often associated with local adverse events. Nanogel formulation of tretinoin has good physical stability and enables good penetration of tretinoin into the pilo-sebaceous glands. Aim: The present study was conducted to assess the efficacy and safety of a nanogel formulation of tretinoin as compared to its conventional gel formulation in the treatment of acne vulgaris of the face. Materials and Methods: This randomized, active controlled, multicentric, phase IV clinical trial evaluated the treatment of patients with acne vulgaris of the face by the two gel formulations locally applied once daily at night for 12 wk. Acne lesion counts (inflammatory, non-inflammatory & total) and severity grading were carried out on the monthly scheduled visits along with the tolerability assessments. Results: A total of 207 patients were randomized in the study. Reductions in the total (72.9% vs. 65.0%; p = 0.03) and inflammatory (78.1% vs. 66.9%; p = 0.02) acne lesions were reported to be significantly greater with the nanogel formulation as compared to the conventional gel formulation. Local adverse events were significantly less (p = 0.04) in the nanogel group (13.3%) as compared to the conventional gel group (24.7%). Dryness was the most common adverse event reported in both the treatment groups while peeling of skin, burning sensation and photosensitivity were reported in patients using the conventional gel only. Conclusion: In the treatment of acne vulgaris of the face, tretinoin nanogel formulation appears to be more effective and better tolerated than the conventional gel formulation. PMID:25738069

    Three women developed severe acne vulgaris within several weeks to a few months after either insertion of a levonorgestrel IUD (two women, 27 and 33 years of age) or subcutaneous implantation of an etonogestrel implant (26-year-old woman). The first woman had had acne previously; her IUD was removed and she was transferred to oral contraception with cyproterone-ethinyloestradiol. The second woman was treated with a peeling cream. The third woman changed to an oral anticonceptive and was treated with isotretinoin. The acne disappeared in all three patients. Progestagens have androgenic activity, even in low doses, and it is well known that androgenic stimulation of the sebaceous glands can cause acne vulgaris. The possibility that acne vulgaris may be an adverse reaction is probably not always considered. When asking the patient about her use of drugs, one should therefore ask specifically about an IUD or a subcutaneous implant.

    Although many cytokines have been implicated in the development and persistence of inflammatory immune responses, it is unknown if any of these are important in inflammatory acne. This study investigated the production of the proinflammatory cytokines interleukin-8 (IL-8), IL-1 beta, and tumor necrosis factor alpha (TNF-alpha) by human monocytic cell lines, ThP-1 and U937, and by freshly isolated peripheral blood mononuclear cells from acne patients. Both Propionibacterium acnes and supernatants obtained from 72-h P. acnes cultures could induce significant concentrations of IL-1 beta, TNF-alpha, and IL-8 by both cell lines and by peripheral blood mononuclear cells as determined by enzyme-linked immunosorbent assay. There was no significant difference between acne and non-acne subjects. Endotoxin quantification and addition of polymyxin B to assays indicated no lipopolysaccharide (LPS) contamination. P. acnes supernatant was fractionated into components with molecular weights of < 3,000, < 10,000, and < 30,000 and assayed for the ability to induce IL-8 and TNF production in ThP-1 cells. Nearly 90% of the original activity was found in the < 30,000-molecular-weight fraction, 50% was in the < 10,000-molecular-weight fraction, and only 15% remained in the < 3,000-molecular-weight fraction. The effluent from the < 3,000-molecular-weight fraction contained about 70% activity, indicating that the inducing factor was not retained in the membrane. Incubation of P. acnes supernatant with various concentrations of mutanolysin or lysozyme resulted in a loss of 60% of the original activity. The addition of jimson lectin, which binds peptidoglycan, resulted in a loss of 70% of the activity in a dose-response manner, whereas peanut lectin had little or no effect on the activity. Heating of the P. acnes supernatant to 65 degrees C also had no effect on the activity. Blocking of CD14, a receptor for both LPS and peptidoglycan, reduced cytokine production by > 50%, suggesting that

    Acne vulgaris can represent a therapeutic challenge in terms of managing ongoing symptoms and preventing scar formation. While the copious variations of available treatments address milder forms of the disease, until recently, therapies for resistant or moderate-to-severe forms were limited to systemic agents that were accompanied by potentially severe side-effects. With the addition of lasers, light sources, and aminolevulinic acid-photodynamic therapy (ALA-PDT) therapies, dermatologists may now have viable new alternatives for treating all grades of acne severity that circumvent the negative side-effects associated with many conventional options.

    Acne vulgaris is a very common skin disorder affecting human beings. There is a paucity of report on the role of heavy metals-lead (Pb) and cadmium (Cd)-globally, and trace metals-zinc (Zn) and copper (Cd)-particularly in Nigeria in the development/severity of acne vulgaris. This study is aimed to determine the blood levels of some heavy metals-cadmium and lead-and trace metals-zinc and copper-in acne vulgaris sufferers in a Nigerian population. Venous blood samples were collected from a total number of 90 non-obese female subjects consisting of 30 mild, 30 moderate and 30 severe acne vulgaris sufferers for blood Cd, Pb, Cu and Zn determination. They were age-matched with 60 females without acne vulgaris who served as the control subjects. Acne sufferers had significantly higher blood Cd and Pb (P = 0.0143 and P = 0.0001 respectively) and non-significantly different blood levels of Cu and Zn (P = 0.910 and P = 0.2140 respectively) compared to controls. There were significant progressive increases in blood levels of Cd and Pb (P = 0.0330 and P = 0.0001 respectively) and non-significant differences in the mean blood level of Cu and Zn (P = 0.1821 and P = 0.2728 respectively) from mild to moderate and severe acne vulgaris sufferers. Increases in blood Cd and Pb may play critical roles in the pathogenesis/severity of acne vulgaris, while Cu and Zn seem to play less significant roles in the development of this disorder in this environment.

    Of 1,203 patients who received radiation treatment for acne vulgaris between 1940 and 1968, 302 patients were recalled and examined, 121 at Geisinger Medical Center and the remainder by their local physicians. Radiation records were reviewed on all patients. Lead-rubber and cones had been used as shielding. Mean age at the time of exposure was 21 years and mean total exposure was 692 R. Palpable nodular thyroid disease was found in eight patients (2.6%). Of these, thyroid carcinoma was detected in two patients (0.66%). Although the number of patients examined was small, the incidence of carcinomas was unexpectedly high. We conclude that follow-up examination is worthwhile for patients previously treated by irradiation for acne vulgaris.

    The objective of this study was to evaluate the effects of isotretinoin on muscle strength, fatigue, and endurance in patients with acne vulgaris. The study included 27 patients with acne vulgaris who underwent treatment with isotretinoin as well as 26 control patients for comparison. Participants in the treatment group received oral isotretinoin 0.5 mg/kg once daily for 1 month followed by an increased dose of 1 mg/kg once daily for 2 months. Isokinetic measurements were obtained from the hamstrings and quadriceps on the nondominant side of the body at baseline and 3-month follow-up using an isokinetic dynamometer. Results indicated that systemic isotretinoin did not significantly alter muscle strength, fatigue, and endurance.

    Background and Objectives: Buthūr-i-Labaniyya (Acne vulgaris) is affecting up to 80% of adolescents and many adults at different stages of life. It is one of the commonest skin disorders which appears on cheeks and nose as white eruptions that seems like solidified milk drops. These eruptions are treated by drugs having properties of tajfīf wa taḥlīl (desiccant and resolving), as mentioned by Ibne Sina. Daood Antaki in his book Tazkira Oolulalbab recommends the local application of a paste of Shonīz (nigella sativa), Naushādar (ammonium chloride) and Būra Armani mixed with Sirka (vinegar) for effective treatment of Acne vulgaris. Methods: The study was observational self comparison before and after treatment, conducted in the OPD of the hospital which is part of the National Institute of Unani Medicine, Bangalore. The duration of study was one year. 40 Female patients with combination of comedones, papules, pustules and nodules were recruited for this purpose. The test drug, Shonīz, Būra Armani, Naushadar powder, mixed with sirka were applied locally for one month with taqlīl-i-ghidhā tadābīr (low calorie index diet). All subjects were assessed on the basis of changes in subjective and objective parameters. Results: The response of test drugs was statistically highly significant (P < 0.01) by using ANOVA repeated measure test, there was also relief in subjective parameters. Subjects reported a reduction of 82.6%, 80.9%, 66.6% in tenderness, itching and irritation respectively. Interpretation and Conclusion: The present study reveals that the test drug formulation is safe and effective in treating Acne vulgaris if used along with low calorie index diet. No side effects of drugs were reported, therefore the trial formulation can be recommended to manage Acne vulgaris of mild to severe degree as a therapy. PMID:26865747

    This study was undertaken to evaluate the clinical efficacy, safety, and histological changes induced by dietary omega-3 fatty acid and γ-linoleic acid in acne vulgaris. A 10-week, randomised, controlled parallel dietary intervention study was performed in 45 participants with mild to moderate acne, which were allocated to either an omega-3 fatty acid group (2,000 mg of eicosapentaenoic acid and docosahexaenoic acid), a γ-linoleic acid group (borage oil containing 400 mg γ-linoleic acid), or a control group. After 10 weeks of omega-3 fatty acid or γ-linoleic acid supplementation, inflammatory and non-inflammatory acne lesions decreased significantly. Patient subjective assessment of improvement showed a similar result. Heamatoxylin & eosin staining of acne lesions demonstrated reductions in inflammation and immunohistochemical staining intensity for interleukin-8. No severe adverse effect was reported. This study shows for the first time that omega-3 fatty acid and γ-linoleic acid could be used as adjuvant treatments for acne patients.

    Misconceptions exist in the community regarding factors that exacerbate acne vulgaris. In particular stress, diet, lifestyle and personal hygiene are often erroneously claimed to be important factors. In order to investigate whether these common misconceptions persist in medical graduates, we analysed the answers of 215 sixth year medical students, who all subsequently graduated from The University of Melbourne, to a short-answer question on acne management and exacerbating factors in one of their final year examination papers. With respect to exacerbating factors, 67% of students identified stress, 10% identified lifestyle factors (smoking and alcohol consumption), and 25% claimed poor facial hygiene exacerbated acne. Diet was stated to be an important factor by 41% of students, of whom 12% specifically mentioned chocolate. Persistence of these misconceptions among medical graduates is likely to perpetuate misinformation in the community.

    The authors administered to 20 patients with acne vulgaris (14 patients with the papulopustulous form of acne, 6 patients with the indurative or cystic form of acne) the preparation STAVA inj. After treatment they evaluated the therapeutic effect of the preparation and the state of immunity of the patient. Treatment failed in three patients with the cystic form where there was a severe deficiency of the cellular immunity component. In six patients, where the cellular immunity was deficient treatment was satisfactory and it was almost restored to normal after treatment. In 11 patients the authors recorded an excellent therapeutic effect already after three weeks' administration and after treatment they recorded complete recovery of cellular immunity. The authors recommend this immunomodulating treatment when other treatment is not effective or contraindicated. In the conclusion they emphasize that STAVA inj. are an excellent immunostimulating preparation when cellular immunity is deficient. The therapeutic effect is good and so is the tolerance; there are no side-reactions.

    Background: Acne vulgaris, a common human skin condition, is an inflammatory disease characterized by comedones, papules, nodules and possibly scarring. This study aimed to evaluate the efficacy of a combination of 5% dapsone gel plus oral isotretinoin in the treatment of acne vulgaris. Materials and Methods: A randomized, placebo-controlled, study was carried out on patients with moderate to severe acne. The patients were randomly divided in two groups: (dapsone gel and vehicle gel). All Patients were administered oral isotretinoin 20 mg daily and topical gel twice a day for 8 weeks. The Global Acne Assessment Score (GAAS), the number lesions and side-effects were documented at base line and weeks 4, 8 and 12. Results: A total of 58 patients (age range: 18-25 years) were included in our study. The number of lesions was significantly lower in the dapsone-treated group at all follow-up visits (P < 0.001). The mean GAAS score in the dapsone-treated group and in the Placebo-treated group decreased, but there was no statistical difference in two groups (P < 0.001). The side-effects on the dapsone-treated group were a mild burning sensation in 7 patients (24.13%), mild erythema of the skin and mild dryness in 4 (13.79%) and 3 (10.34%) cases respectively (P < 0.001). In our study, adverse effects were common but they were minor and tolerable. No clinically significant changes in laboratory parameters were observed (P < 0.001). Conclusions: Dapsone gel was an effective medication for patients who received isotretinoin for acne vulgaris treatment resulting in a significant reduction of the number of lesions. PMID:25250291

    Acne is one of the most common dermatological diseases, and obsessive compulsive disorder is among the most frequent psychiatric conditions seen in dermatology clinics. Comorbidity of these conditions may therefore be expected. The aim of this study was to measure obsessive compulsive symptoms and quality of life in patients with acne vulgaris, compare them with those of healthy control subjects, and determine whether there is any predictive value of obsessive compulsive symptoms for quality of life in patients with acne. Obsessive compulsive symptoms and quality of life measurements of 146 patients with acne vulgaris and 94 healthy control subjects were made using the Maudsley Obsessive Compulsive Questionnaire and Short Form-36 in a cross-sectional design. Patients with acne vulgaris had lower scores for physical functioning, physical role dysfunction, general health perception, vitality, and emotional role dysfunction. They also had higher scores for checking, slowness, and rumination. The only predictor of physical functioning and vitality dimensions of health-related quality of life in these patients was rumination score. Obsessive compulsive symptoms in patients with acne vulgaris are higher than in controls, and this may correlate with both disease severity and quality of life for patients.

  17. Is switching retinoids a sound strategy for the treatment of acne vulgaris?

    Gold, Linda Stein; Colón, Luz E; Johnson, Lori A; Gottschalk, Ronald W

    2008-06-01

    Topical retinoids, such as adapalene gel and tazarotene cream, are considered first-line therapy for the treatment of acne vulgaris. Dermatologists often initiate adapalene gel treatment first, due to its good tolerability, followed by a switch to tazarotene cream in an effort to improve or hasten efficacy outcomes. The goal of this study was to compare the efficacy and safety of 2 daily regimens for the treatment of acne: adapalene 0.1% gel for 12 weeks and adapalene 0.1% gel for 6 weeks followed by tazarotene 0.1% cream for 6 weeks. The primary efficacy outcome was the percent of reduction in total lesion counts posttreatment. Subjects ages 12 to 35 years with acne vulgaris were selected to participate in a 12-week, randomized, evaluator-blind study of once-daily therapy with adapalene 0.1% gel (n=101) or "switch therapy," adapalene 0.1% gel followed by tazarotene 0.1% cream (n=100). Adapalene-treated subjects achieved similar percent reductions in total lesion counts at week 12 compared to subjects receiving switch therapy, demonstrating the noninferiority of adapalene gel treatment (median difference: -3.57%; lower confidence limit [LCL]: -11.25). Adapalene gel was associated with fewer reports of cutaneous irritation, particularly for scaling and stinging/burning, and fewer treatment-related adverse events compared to switch therapy. The results of this study indicate that daily therapy with adapalene 0.1% gel for 12 weeks was noninferior to switch therapy.

  18. Selection of therapy for acne vulgaris: balancing concerns about antibiotic resistance.

    PubMed

    Del Rosso, James Q

    2008-11-01

    The widespread use of long-term antibiotics to treat acne and rosacea has resulted in increased Propionibacterium acnes resistance to antibiotics. Although resistance may decrease treatment effectiveness in some cases, it also is clear that antimicrobial activity is not the only role antibiotics play in acne management. The anti-inflammatory activity of antibiotics contributes to antipropionibacterial efficacy. In addition, the use of benzoyl peroxide (BPO) in combination with antibiotics to reduce resistant populations of propionibacteria is widely advocated, as P acnes has not developed resistance to it. P acnes now is known to form biofilms, which are bacterial communities that live encased in a glycocalyx polymer that aids in adherence to surfaces, thereby delaying antibiotic penetration. In addition to drug resistance, patient compliance with acne treatment is an important issue. Because compliance is a function of tolerability and convenience, new moisturizing noncomedogenic vehicles and fixed BPO-antibiotic combinations can be expected to improve compliance. Better efficacy has been noted with BPO-antibiotic combination therapy.

    Objectives: To evaluate the effectiveness of topical 5-aminolevulinic acid (ALA)- medicated photodynamic therapy (ALA PDT) for the treatment of moderate to severe acne vulgaris. Methods: Sixteen Chinese patients with moderate to severe facial acne were treated with 1-3 courses of ALA PDT. ALA cream (3%) was freshly prepared and applied to acne lesions for 3-4 h. The lesions were irradiated by a 635 nm diode laser at dose levels of 60 - 80 J/cm2 at 100 mW/cm2. Clinical assessments were conducted before and after treatment up to 3 months. Results: All patents showed response to ALA PDT. Complete clearance was seen in 10 patients (62.5%) and partial clearance in 6 patients (37.5%). One case showed recurrence after complete clearance at 2 months and another two showed recurrence after complete clearance at 3 months. However, the number of new lesions were significantly reduced. Adverse effects were minimal. Conclusions: The results of this preliminary clinical study is encouraging. ALA PDT is a simple, safe and useful therapeutic option for the treatment of moderate to severe acne. Further studies to evaluate the treatment with a larger number of patients and for a longer period of follow-up are needed.

  20. Acne vulgaris, probiotics and the gut-brain-skin axis: from anecdote to translational medicine.

    PubMed

    Bowe, W; Patel, N B; Logan, A C

    2014-06-01

    Acne vulgaris has long been postulated to feature a gastrointestinal mechanism, dating back 80 years to dermatologists John H. Stokes and Donald M. Pillsbury. They hypothesised that emotional states (e.g. depression and anxiety) could alter normal intestinal microbiota, increase intestinal permeability, and contribute to systemic inflammation. They were also among the first to propose the use of probiotic Lactobacillus acidophilus cultures. In recent years, aspects of this gut-brain-skin theory have been further validated via modern scientific investigations. It is evident that gut microbes and oral probiotics could be linked to the skin, and particularly acne severity, by their ability to influence systemic inflammation, oxidative stress, glycaemic control, tissue lipid content, and even mood. This intricate relationship between gut microbiota and the skin may also be influenced by diet, a current area of intense scrutiny by those who study acne. Here we provide a historical background to the gut-brain-skin theory in acne, followed by a summary of contemporary investigations and clinical implications.

    2015-01-01

    Acne vulgaris is a common and chronic skin disease, and is a frequent source of morbidity for affected patients. Treatment of acne vulgaris is often difficult due to the multifactorial nature of this disease. Combination therapy, such as that containing clindamycin and benzoyl peroxide, has become the standard of care. Several fixed formulations of clindamycin 1% and benzoyl peroxide of varying concentrations are available and have been used with considerable success. The major limitation is irritation and dryness from higher concentrations of benzoyl peroxide, and a combination providing optimal efficacy and tolerability has yet to be determined. Recently, a clindamycin and benzoyl peroxide 3.75% fixed combination formulation was developed. Studies have suggested that this formulation may be a safe and effective treatment regimen for patients with acne vulgaris. Here, we provide a brief review of acne pathogenesis, benzoyl peroxide and clindamycin, and profile a new Clindamycin-BP 3.75% fixed combination gel for the treatment of moderate-to-severe acne vulgaris.

    Background: Oral isotretinoin is highly effective in all forms and grades of acne, even in lower dosages (<0.5 mg/kg/day). There is a paucity of comparative data on the various low-dose regimens of oral isotretinoin in the Indian literature. Objectives: To assess and compare the efficacy and tolerability of two low-dose oral isotretinoin treatment regimens (20 mg daily and 20 mg alternate days) in moderate to severe acne vulgaris. Materials and Methods: A total of 240 patients with moderate to severe acne vulgaris were selected and randomized into two groups and treated with a fixed dose of 20 mg of isotretinoin (Group A - daily and Group B - alternate days) for 24 weeks and followed up for 12 weeks post therapy. Results: A total of 234 patients completed the study. At the end of therapy, decrease in the total acne loads up to 98.99% (Group A) and 97.69% (Group B) was achieved from the baseline (P < 0.01), excellent response was observed in 98.3% (Group A) and 93.96% (Group B) patients (P = 0.166). In the severe acne, Group A performed significantly better than Group B until the end of 36 weeks. While in the moderate acne, significant difference in the response between both groups was observed only up to 12 weeks. No serious side effect was observed. Conclusion: Both isotretinoin regimens were well tolerated and found to be an effective treatment for moderate to severe acne vulgaris. However, in moderate acne 20 mg alternate day regimen may be preferred. A 20 mg daily regimen is a better choice for severe acne in terms of response. Limitation: Small sample size and short follow-up period. PMID:27730033

    Bilateral 2.5 and 3.0 mm nasal bone osteophytes developed five weeks following the initiation of oral isotretinoin therapy (50 mg daily) for severe cystic acne vulgaris in a healthy 30-year-old white woman who had undergone uneventful rhinoplasty 12 years earlier. Histologically mature bone fragments were removed at surgery. Vitamin A and its analogs have been reported to cause hyperostosis of the vertebrae and long bones, but no known reports link them to nasal bone changes. Clinically significant nasal bone osteophytosis may be another adverse reaction to oral isotretinoin therapy.

    The management of acne in South-East Asia is unique, as Asian skin and local variables require a clinical approach unlike that utilized in other parts of the world. There are different treatment guidelines per country in the region, and a group of leading dermatologists from these countries convened to review these guidelines, discuss current practices and recent advances, and formulate consensus guidelines to harmonize the management of acne vulgaris in the region. Emphasis has been placed on formulating recommendations to impede the development of antibiotic resistance in Propionibacterium acnes. The group adopted the Acne Consensus Conference system for grading acne severity. The group recommends that patients may be treated with topical medications including retinoids, benzoyl peroxide (BPO), salicylic acid, a combination of retinoid and BPO, or a combination of retinoids and BPO with or without antibiotics for mild acne; topical retinoid with topical BPO and a oral antibiotic for moderate acne; and oral isotretinoin if the patient fails first-line treatment (a 6- or 8-week trial of combined oral antibiotics and topical retinoids with BPO) for severe acne. Maintenance acne treatment using topical retinoids with or without BPO is recommended. To prevent the development of antibiotic resistance, topical antibiotics should not be used as monotherapy or used simultaneously with oral antibiotics. Skin care, comprised of cleansing, moisturizing and sun protection, is likewise recommended. Patient education and good communication is recommended to improve adherence, and advice should be given about the characteristics of the skin care products patients should use.

    Today acne vulgaris is a disease which can be well controlled using a combination of topical, systemic, and physical therapeutic modalities. However, successful acne management depends to a large extent on physician interest and the ability of the physician to apply therapy to the evolutionary stage of the disease and to the disturbed pathogenetic mechanisms. It is this author's opinion that grades I and II comedonal and papulopustular acne can be effectively treated solely with topical preparations, particularly the concurrent use of tretinoin with benzoyl peroxide or topical antibiotics. The majority of patients with grades III and IV inflammatory disease require oral antibiotics in addition to aggressive topical treatments. Intralesional steroids can be effective in all grades of acne when lesions develop an inflammatory nodulocystic quality. The physician should consider the use of estrogen (in females) or oral vitamin A in the small group of patients with grades III and IV inflammatory-cystic acne that has been unresponsive to conventional therapy. Combined systemic therapies of high-dose antibiotics, systemic corticosteroids, and sulfones clearly take precedence over topical preparations in conglobate acne and acne fulminans. Finally, oral isotretinoin, alone and perhaps in combination with more conventional modalities, should play an important role in the future management of severe inflammatory-cystic acne.

    We evaluated the short-term and long-term effects of the 1550 nm erbium:glass (Er:glass) fractional laser in the treatment of facial acne vulgaris. Forty-five (9 male and 36 female) acne patients were treated 4 times at 4-week intervals with the following parameters: 169 spot density and 15-30 mJ/cm(2) fluence. There was no control group. The laser spots were adjustable (maximum overlap: 20%) according to the treatment area, and delivered in rows in order to cover all the face. Clinical photographs were taken. The IGA scores and lesion counts were performed for each treatment. Their current state was obtained by phone call follow-up to determine the long-term effect and photographs were offered by themselves or taken in hospital. After four treatments, all patients had an obvious reduction of lesion counts and IGA score and the peak lesion counts decreased to 67.7% after the initial four treatment sessions. For long-term effect, 8 patients lost follow-up, hence 37 patients were followed-up. 8 patients were 2-year follow up, 27 at the 1-year follow-up, and all patients at the half-year follow-up. The mean percent reduction was 72% at the half-year follow-up, 79 at the 1-year follow-up and 75% at the 2-year follow-up. Side effects and complications were limited to transient erythema and edema, and few patients suffered from transient acne flare-ups and sensitivity. All patients responded that their skin was less prone to oiliness. In conclusion, acne can be successfully treated by 1550 nm Er:glass fractional laser, with few side effects and prolonged acne clearing.

    Importance Describing the relationship between the availability of free prescription drug samples and dermatologists’ prescribing patterns on a national scale can help inform policy guidelines on the use of free samples in a physician’s office. Objective To investigate the relationships between free drug samples and dermatologists’ local and national prescribing patterns and between the availability of free drug samples and prescription costs. Design, Setting, and Participants Cross-sectional study investigating prescribing practices for acne, a common dermatologic condition for which free samples are often available. The settings were, first, the offices of a nationally representative dermatologists from the National Disease and Therapeutic Index (an IMS Health Incorporated database) and, second, an academic medical center clinic without samples. Participants were ambulatory patients who received a prescription from a dermatologist for a primary initial diagnosis of either acne vulgaris or acne rosacea in 2010. Main Outcome Measures National trends in dermatologist prescribing patterns, the degree of correlation between the availability of free samples and the prescribing of brand-name medications, and the mean cost of acne medications prescribed per office visit nationally and at an academic medical center without samples. Results On a national level, the provision of samples with a prescription by dermatologists has been increasing over time, and this increase directly correlates with the use of the branded generic drugs promoted by these samples. Branded and branded generic drugs comprised most of the prescriptions written nationally (79%), while they represented only 17% at an academic medical center clinic without samples. Because of the increased use of branded and branded generic drugs, the national mean total retail cost of prescriptions at an office visit for acne was conservatively estimated to be 2 times higher (approximately $465 nationally vs

  9. Interaction and efficacy of Keigai-rengyo-to extract and acupuncture in male patients with acne vulgaris: A study protocol for a randomized controlled pilot trial

    2011-01-01

    Background In consideration of patients seeking to use traditional Chinese medicine, an evidence-based potentiality for safe and effective use of herbal medicine and acupuncture in treatment of acne vulgaris has been suggested. However, despite common use of a combination of herbal medicine and acupuncture in clinical practice, the current level of evidence is insufficient to draw a conclusion for an interaction and efficacy of herbal medicine and acupuncture. Therefore, considering these methodological flaws, this study was designed to assess the interaction and efficacy of an available herbal medicine, Keigai-rengyo-to extract (KRTE), and acupuncture for treatment of acne using the 2 × 2 factorial design and the feasibility of a large clinical trial. Methods/Design A randomized, assessor single blinded, 2 × 2 factorial pilot trial will be conducted. Forty four participants with acne vulgaris will be randomized into one of four groups: waiting list group (WL), KRTE only group (KO), acupuncture only group (AO), and KRTE and acupuncture combined treatment group (KA). After randomization, a total of 8 sessions of acupuncture treatment will be performed twice a week in the AO- and KA groups, respectively. Patients in the KO- and KA groups will be prescribed KRTE 3 times a day at a dose of 7.4 g after meals for 4 weeks. The following outcome measurements will be used in examination of subjects: the mean percentage change and the count change of inflammatory and non-inflammatory acne lesions, the Skindex 29, visual analogue scale (VAS) and investigator global assessment (IGA) from baseline to the end of the trial. Trial Registration The trial is registered with the Clinical Research Information Service (CRiS), Republic of Korea: KCT0000071. PMID:21418585

    Topical retinoids are the cornerstone of therapy for acne vulgaris. Nevertheless, the adjunctive use of other anti-acne agents can help enhance the efficacy of topical retinoids still further. Given that tazarotene 0.1 percent gel has previously shown significantly greater efficacy than tretinoin 0.025 percent gel, it is likely that tazarotene plus clindamycin offers superior efficacy to tretinoin plus clindamycin, which has recently become available as a combination product. A total of 150 patients with facial acne vulgaris were randomly assigned to receive either tazarotene 0.1 percent cream plus clindamycin 1 percent gel, or tretinoin 0.025 percent gel plus clindamycin 1 percent gel. Each medication was applied once daily in the evening (clindamycin followed by the retinoid 5-10 minutes later) for up to 12 weeks. At week 12, the reduction from baseline in lesion counts was greater with tazarotene/clindamycin than tretinoin/clindamycin for both the non-inflammatory lesion count (71% vs. 52%, p< or =.01) and the inflammatory lesion count (77% vs. 67%, P=.053). Tazarotene/clindamycin also resulted in a significantly higher incidence of patients achieving > or = 50 percent global improvement (incidence of 88% vs. 75% at week 12; p< or =.05). Both regimens were similarly well tolerated. In the treatment of facial acne vulgaris, tazarotene plus clindamycin offers significantly greater efficacy than tretinoin plus clindamycin and has comparable tolerability.

    Objective: To compare efficacy, tolerability, and safety of two concentrations of topical SB204 and vehicle twice daily for 12 weeks in the treatment of acne vulgaris. Design: Randomized, double-blind, placebo-controlled, three-arm, Phase 2 study. Setting: Dominican Republic, Panama, and Honduras. Participants: Subjects with acne, age 12 to 40, with 25 to 70 noninflammatory lesions, 20 to 40 inflammatory lesions, and a baseline Investigator’s Global Assessment score of mild, moderate, or severe. Measurements: The primary efficacy assessment was the absolute change in noninflammatory lesion counts. Other assessments included inflammatory lesion counts, success on dichotomized Investigator’s Global Assessment, reported adverse events, physical examinations, laboratory testing, and tolerability. Results: One hundred fifty-three subjects were randomized to vehicle (n=52), SB204 1% (n=51), or SB204 4% (n=50). When compared to vehicle, subjects treated with SB204 1% and SB204 4% had significantly greater mean percent reduction in noninflammatory lesions from baseline and subjects treated with SB204 4% had a significantly greater mean percent reduction in inflammatory lesion count from baseline at Week 12. There were no significant differences in the IGA success rates between groups. Both concentrations of SB204 were safe and well-tolerated. Conclusions: When compared to vehicle, both SB204 1% and SB204 4% significantly decreased the percentage of noninflammatory lesions and SB204 4% also significantly decreased the percentage of inflammatory lesions in subjects with acne vulgaris treated for 12 weeks. Treatment with SB204 1% and SB204 4% was safe and well-tolerated. Registry: clinicaltrials.gov (NCT01844752). PMID:27672413

    Adapalene 0.1%/benzoyl peroxide 2.5% gel (Epiduo™, Tactuo™) is the only fixed-dose combination product available that combines a topical retinoid with benzoyl peroxide; it targets three of the four main pathophysiologic factors in acne. This article reviews the therapeutic efficacy and tolerability of topical adapalene 0.1%/benzoyl peroxide 2.5% gel in the treatment of patients aged ≥ 12 years with acne vulgaris, as well as summarizing its pharmacologic properties. In three 12-week trials in patients aged ≥ 12 years with moderate acne, success rates were significantly higher with adapalene 0.1%/benzoyl peroxide 2.5% gel than with adapalene 0.1% gel or benzoyl peroxide 2.5% gel alone, and combination therapy had an earlier onset of action. In addition, significantly greater reductions in total, inflammatory, and noninflammatory lesion counts were seen in patients receiving adapalene 0.1%/benzoyl peroxide 2.5% gel than in those receiving adapalene 0.1% gel or benzoyl peroxide 2.5% gel alone. Adapalene 0.1%/benzoyl peroxide 2.5% gel did not significantly differ from clindamycin 1%/benzoyl peroxide 5% gel in terms of the reduction in the inflammatory, noninflammatory, or total lesion counts in patients with mild to moderate acne, according to the results of a 12-week trial. Twelve-week studies showed that topical adapalene 0.1%/benzoyl peroxide 2.5% gel in combination with oral lymecycline was more effective than oral lymecycline alone in patients with moderate to severe acne, and topical adapalene 0.1%/benzoyl peroxide 2.5% gel in combination with oral doxycycline hyclate was more effective than oral doxycycline hyclate alone in patients with severe acne. In patients with severe acne who responded to 12 weeks' therapy with topical adapalene 0.1%/benzoyl peroxide 2.5% gel plus oral doxycycline hyclate or oral doxycycline hyclate alone, an additional 6 months' therapy with adapalene 0.1%/benzoyl peroxide 2.5% gel was more effective than vehicle gel at

    In the course of producing the 2009 NHS Evidence--skin disorders Annual Evidence Update on Acne Vulgaris, 25 randomised controlled trials were examined. From these, at least 12 potentially serious problems of trial reporting were identified. Several trials concluded no effect of a treatment yet they were insufficiently powered to exclude potentially useful benefits. There were examples of duplicate publication and "salami publication", as well as two trials being combined and reported as one. In some cases, an incorrect "within-groups" statistical comparison was made and one trial report omitted original efficacy data and included only P values. Both of the non-inferiority studies examined failed to pre-specify a non-inferiority margin. Trials reported as "double-blind" compared treatments that were dissimilar in appearance or had differing adverse effect profiles. In one case an intention-to-treat analysis was not performed and there was a failure to account for all of the randomized participants. Trial results were made to sound more impressive by selective outcome reporting, emphasizing the statistical significance of treatment effects that were clinically insignificant, and by the use of larger-sounding odds ratios rather than rate ratios for common events. Most of the reporting problems could have been avoided by use of the CONSORT guidelines and prospective trial registration on a public clinical trials database.

    Acne vulgaris is a common skin disorder that affects most individuals at some point in their lives. It may result in significant morbidity, including cutaneous scarring and psychological impairment. Current treatments include topical retinoids, benzoyl peroxide, topical and systemic antibiotics, and systemic isotretinoin. There are growing concerns of rising antibiotic resistance, significant side effects of isotretinoin therapy, and lack of safe and effective treatment for pregnant females. Recent advances in the pathogenesis of acne have led to a greater understanding of the underlying inflammatory mechanisms and the role the Propionibacterium acnes and biofilms. This has led to the development of new therapeutic targets. This article reviews emerging treatments of acne, including topical picolinic acid, topical antibiotic dapsone, systemic zinc salts, oral antibiotic lymecycline, new formulations of and synergistic combinations of benzoyl peroxide, photodynamic therapy with topical photosensitizers and potential acne vaccines.

    Although acne vulgaris is common in preadolescents (<13 yrs), few acne treatments are currently approved for children. This study assessed the safety and efficacy of tretinoin microsphere gel (TMG) 0.04% pump in children aged 9-11 with acne vulgaris. In this multicenter, randomized, double-blind, vehicle-controlled pilot study, patients applied TMG 0.04% pump or vehicle once daily to the face for 12 weeks. Efficacy measures were changes in facial lesion counts, Investigator Global Evaluation of acne severity using two scales, and Investigator Global Assessment of Improvement from baseline to week 12. Of the 110 patients enrolled, 55 received TMG 0.04% pump, and 55 received vehicle. At week 12, there was significantly greater improvement in the least-squares mean change in noninflammatory lesions with TMG 0.04% than with vehicle (-19.9 vs -9.7, p = 0.04) and a significant difference in Investigator Global Assessment of improvement at week 12 between the children treated with TMG 0.04% pump and those treated with vehicle (p = 0.02), but there were no discernible differences in static acne severity scales. Change from baseline in signs and symptoms of cutaneous irritation were similar between the active and vehicle arms at week 12. This study demonstrated statistically significant differences in the reduction of noninflammatory lesions between TMG 0.04% pump and vehicle in patients aged 9-11 with acne vulgaris. Additional studies are warranted to further characterize the safety and efficacy of TMG 0.04% pump for the treatment of acne in the preadolescent population.

    Background Acne vulgaris (acne) is the most common skin disorder producing physical and emotional scars that can persist for years. An estimated 83% of acne sufferers self-treat, but there is lack of studies documenting the effectiveness of over-the-counter (OTC) acne treatment products. Objective This study was conducted to determine the effectiveness of an OTC, 3-step, anti-acne skincare regimen in treating acne and improving the appearance of red/inflamed facial skin. Methods This 6-week, open-label clinical study included both genders aged between 12 and 35 years with mild-to-moderate acne. All subjects were required to have an acne score of 1–3 (Cook’s acne grading scale: 0=clear to 7=very severe) and a moderate redness score of ≥2 (0=none and 4=severe). Subjects completed a 3-step facial treatment regimen every morning and evening using an OTC cleanser, toner, and acne treatment. Evaluations for effectiveness and safety were done at baseline and weeks 2, 4, and 6 using digital photographs (Visia-CR® digital imaging system) of the face and analyzed using Image-Pro® software for the grading of acne, red/inflamed skin, and the number and type of lesions. Results Thirty subjects (12 males and 18 females) were enrolled (mean age of 19 years; range 12–34 years). This skincare regimen resulted in statistically significant improvements in acne grading scores after 2 weeks of use, with mean scores continuing to improve after 4 and 6 weeks of use (P<0.001). Statistically significant improvements from baseline in red/inflamed skin, open and closed comedones, and papules were detected at all time points and for nodules at week 6, compared to their respective baselines (P<0.05). Conclusion This clinical study demonstrated the effectiveness of an OTC 3-step, anti-acne skincare regimen in significantly improving acne and the overall appearance of skin in the majority of subjects who had mild-to-moderate acne.

    Antibiotics are widely applied in management of acne vulgaris, which raises the issue of antibiotic resistance. Due to improper application and supervision of antibiotics, antibiotic resistance has become a serious problem in China. So, the efficacy of antimicrobial therapy in acne is unclear without an objective monitor of antibiotic resistance of Propionibacterium acnes. This cross-sectional, multicenter observational study is aimed at understanding the status of antibiotic resistance in P. acnes, investigating the measures of acne management in China and analyzing the genotypes of antibiotic-resistant strains of P. acnes. Altogether, 312 strains of P. acnes were collected from patients in five medical centers across central China after reviewing the corresponding medical history in detail. The samples underwent antibiotic susceptibility assays by agar dilution method with a total of 11 classes of antibiotics being tested. The antibiotic-resistant strains were screened and further analyzed by investigation of the genotypes regarding 23S rRNA, 16S rRNA and erm(X). The predominant resistance occurred in macrolides and lincomycin with an overall resistance rate of 47.8%. The resistance to tetracyclines was scarce with only two cases identified. The emergence of minimum inhibitory concentration elevation for tetracyclines is associated with its application history (P < 0.005). The genotypes of the reported macrolide-lincosamide-streptogramin B resistance strains were also spotted in Chinese subjects while other resistance determinants may also exist. The tetracyclines have been proved to be vastly susceptible while macrolides and lincomycin face a serious resistance status in China.

    Glycolic acid chemical peeling is effective for treating comedones, and some clinical data show that it also improves inflammatory eruptions. The purpose of this study was to identify the mechanism of glycolic acid chemical peeling to improve inflammatory acne. To assess growth inhibitory and bactericidal effects of glycolic acid on Propionibacterium acnes in vitro, we used an agar diffusion method and a time-kill method. To reveal bactericidal effects in vivo, we established an agar-attached method which correlated well with the ordinary swab-wash method, and we used the agar-attached method to compare the numbers of propionibacteria on the cheek treated with glycolic acid chemical peeling. Our results show that 30% glycolic acid (at pH 1.5, 3.5 and 5.5) formed growth inhibitory circles in the agar diffusion method, but the diameters of those circles were smaller than with 1% nadifloxacin lotion or 1% clindamycin gel. In the time-kill method, 30% glycolic acid (at pH 1.5 and 3.5) or 1% nadifloxacin lotion reduced the number of P. acnes to less than 100 CFU/mL within 5 min. In contrast, in 30% glycolic acid (at pH 5.5) or in 1% clindamycin gel, P. acnes survived for more than 4 h. Chemical peeling with 35% glycolic acid (at pH 1.2) decreased the number of propionibacteria on the cheeks of patients compared with untreated controls (P < 0.01). Our results demonstrate that glycolic acid has moderate growth inhibitory and bactericidal effects on P. acnes, and that chemical peeling with glycolic acid works on inflammatory acne via those effects.

    As the first barrier to environmental exposures, human skin has developed an integrated immune system to protect the inner body from chemical, physical or microbial insults. Microorganisms inhabiting superficial skin layers are known as skin microbiota and include bacteria, viruses, archaea and fungi. The microbiota composition is crucial in the instruction and support of the skin's immune system. Changes in microbiota can be due to individual, environmental or behavioral factors, such as age, climate, hygiene or antibiotic consumption, which can cause dysbiosis. The contribution of skin microbiota to disease development is known in atopic dermatitis, where there is an increase in Staphylococcus aureus. Culture-independent studies have enabled more accurate descriptions of this complex interplay. Microbial imbalance is associated with the development of various diseases. This review focuses on microbial imbalances in acne vulgaris and rosacea.

    Topical therapy is the first choice for the treatment of mild to moderate acne and all-trans retinoic acid is one of the most used drugs. The combination of retinoids and antimicrobials is an innovative approach for acne therapy. Recently, lauric acid, a saturated fatty acid, has shown strong antimicrobial activity against Propionibacterium acnes. However, topical application of retinoic acid is followed by high incidence of side-effects, including erythema and irritation. Solid lipid nanoparticles represent an alternative to overcome these side-effects. This work aims to develop solid lipid nanoparticles loaded with retinoic acid and lauric acid and evaluate their antibacterial activity. The influence of lipophilic stearylamine on the characteristics of solid lipid nanoparticles was investigated. Solid lipid nanoparticles were characterized for size, zeta potential, encapsulation efficiency, differential scanning calorimetry and X-ray diffraction. The in vitro inhibitory activity of retinoic acid-lauric acid-loaded solid lipid nanoparticles was evaluated against Propionibacterium acnes, Staphylococcus aureus and Staphylococcus epidermidis. High encapsulation efficiency was obtained at initial time (94 ± 7% and 100 ± 4% for retinoic acid and lauric acid, respectively) and it was demonstrated that lauric acid-loaded-solid lipid nanoparticles provided the incorporation of retinoic acid. However, the presence of stearylamine is necessary to ensure stability of encapsulation. Moreover, retinoic acid-lauric acid-loaded solid lipid nanoparticles showed growth inhibitory activity against Staphylococcus epidermidis, Propionibacterium acnes and Staphylococcus aureus, representing an interesting alternative for the topical therapy of acne vulgaris.

    To clarify the influence of the fatty acid composition of sebum in acne vulgaris, we investigated the amounts and fatty acid compositions of triglycerides (TG) and free fatty acids (FFA), and the amounts of cutaneous superficial Propionibacterium acnes in acne patients and healthy subjects. The foreheads of 18 female patients, 10 male patients, 10 healthy females and 10 healthy males were studied in a Japanese population. There were significant differences in the amounts of sebum, TG and cutaneous superficial P. acnes, as well as the fatty acid compositions of TG and FFA between acne patients and healthy subjects in females. Their fatty acid compositions were correlated with the amount of TG with or without acne. It was clarified that the fatty acid compositions of TG and FFA depended on the amount of TG, and there were no differences in the fatty acid composition in the presence and absence of acne.

    Seven naturally derived components from hop plant (Humulus lupulus L.) extracts were tested for evaluation of biological activities affecting acne vulgaris. Five strains, Propionibacterium acnes, Staphylococcus epidermidis, Staphylococcus aureus, Kocuria rhizophila and, Staphylococcus pyogenes, were selected as the main acne-causing bacteria. Hop extracts xanthohumol and the lupulones showed strong inhibitory activities against all of the strains. Although hydrogenated derivatives did not show the same level of activity, naturally occurring xanthohumol, humulones, and lupulones all showed moderate to strong anticollagenase inhibitory activities. Antioxidant capacity was also evaluated with seven different methods based on different reactive oxygen species. Xanthohumol showed the highest activity in total oxygen radical absorbance capacity as well as singlet oxygen absorbance capacity.

    Acne vulgaris is a debilitating disorder and requires proper treatment. This work evaluates the clinical efficacy, side effects, and laboratory changes of serum lipids and liver function during oral isotretinoin therapy for acne vulgaris, comparing single versus twice daily dose. Fifty-eight patients with acne vulgaris were included and randomized into group I (26 patients), who received once daily dose, and group II (32 patients), who received twice daily dose of oral isotretinoin. Global acne scoring system was used to evaluate acne severity and post-treatment improvement. Both regimens resulted in highly significant clinical improvement of acne with no significant difference. However, side effects were significantly more common among patients of group I. Both regimens caused mild rise of serum cholesterol, alanine transaminase (ALT), and aspartate aminotransferase (AST) with more prominent rise of triglycerides especially with twice daily dose. Oral isotretinoin is a very effective treatment for acne vulgaris with no statistically significant difference in clinical efficacy between once and twice daily doses. However, dividing dose to twice per day might cause fewer incidence of side effects without reducing clinical efficacy. The drug causes mild clinically insignificant rise of serum cholesterol, triglycerides, AST, and ALT.

    The cause of acne is still obscure, but genetic predisposition, sebaceous overactivity, overgrowth of bacterial flora and exposure to comedogenic substances are all significant factors. Acne lesions occur mainly in sebaceous follicles, which are characterized by deep follicular canals and large sebaceous glands. The associated seborrhea is not due to a circulatory excess of androgens but may be caused by a local amplification of androgenic activity. This, in turn, may be due to large numbers of androgen receptors and a high concentration of enzymes such as 17beta-hydroxysteroid dehydrogenase, within the sebaceous gland itself. Hyperkeratosis of the retention type in the pilary infrainfundibulum obstructs the outflow of sebum and keratin flakes. This favors the proliferation of Propionibacterium acnes which may initiate inflammation in microcomedos and lead to formation of pustules, papules or nodules. Topical therapy with tretinoin, benzoyl peroxide and antibiotics such as clindamycin is widely used today. Oral tetracyclines and other chemotherapeutic agents remain necessary in severe cases.

    Patients often perceive the cause of their acne to be related to a lack of proper cleansing, therefore many patients attempt to treat their acne either alone or with prescription therapy by frequent aggressive cleansing with harsh cleansing agents. Altered epidermal barrier function, inflammation, and Propionibacterium acnes are related to acne vulgaris (AV) pathophysiology; proper cleansing can favorably modulate the development of AV. The available clinical studies support gentle cleansing in AV by showing the ability to contribute to improving AV lesion counts and severity and minimizing the irritation seen with topical AV therapies such as retinoids and BP.

    Objective: To evaluate the efficacy and tolerance of a combined 445nm/630nm light therapy mask for the treatment of mild-to-moderate acne vulgaris with and without topical 1% salicylic acid with retinol versus 2.5% benzoyl peroxide. Design: A 12-week evaluator-blinded, randomized study. Subjects were randomized to be treated with the 445nm/630nm light therapy mask alone, benzoyl peroxide, or 445nm/630nm light therapy mask with topical 1% salicylic acid with retinol. Participants: Healthy male and female subjects 12 to 35 years old with Fitzpatrick skin types I to VI and mild-to-moderate facial acne vulgaris. Measurements: The primary endpoint was the change in the number of inflammatory acne lesions after 12 weeks of treatment. Secondary endpoints included the change in noninflammatory acne lesions, change in total acne lesions, change in Investigator Global Acne Assessments, and overall responder rate. Results: 445nm/630nm light therapy mask-treated subjects showed a 24.4-percent improvement in inflammatory acne lesions (p<0.01) versus 17.2 percent (p<0.05) and 22.7 percent (p<0.01) in benzoyl peroxide and 445nm/630nm light therapy mask with topical 1% salicylic acid with retinol, respectively, a 19.5-percent improvement in noninflammatory lesions (p<0.001) versus 6.3 and 4.8 percent for benzoyl peroxide and 445nm/630nm light therapy mask with topical 1% salicylic acid with retinol, respectively. Subjects in the 445nm/630nm light therapy mask group also achieved a 19.0-percent improvement in the Investigator Global Acne Assessment (p<0.001) versus 4.7 percent in benzoyl peroxide and 13.9 percent in 445nm/630nm light therapy mask with topical 1% salicylic acid with retinol (p<0.01). Treatments were well-tolerated overall with trends toward less early irritation in the 445nm/630nm light therapy mask group. Conclusion: 445nm/630nm light therapy mask appears to be a safe and effective therapy for mild-to-moderate acne. PMID:27354885

    Summary Background Since vitamin D is a recent known immunoregulatory factor in some diseases which are addressed in immune system disorders such as SLE, [psoriasis] and others. Objective To determine the serum levels of 25-hydroxy vitamin D3 [25(OH)D] in patients with acne vulgaris and its association with clinical features. Methods This cross-sectional study was conducted over months. This study included 39 patients with acne vulgaris and 40 healthy controls. Subjects who did not use alcohol, vitamin D supplements, oral steroids or PUVA and/or NBUVB for more than three months were included. Serum 25(OH)D levels were measured. Baseline demographics, family history and comorbidities like PCO were recorded. Statistical analyses were performed using SPSS 16.0.0. Results The median concentration of 25(OH)D was 8.4 ng/mL (range: 1.4–99) in patients and 10.4 ng/mL (range: 3.1–56.7) in controls, with no statistical significant difference. PCOS was a significant predictor of the occurrence of acne vulgaris (OR=6.25; 95% CI: 1.52–25.66; p=0.01). There were no significant associations between severity of disease and serum 25(OH)D levels (rs=−0.12, p=0.45), age (rs=−0.28, p=0.09), BMI (rs=−0.12, p=0.46), age at onset of disease (rs=−0.08, p=0.63) and duration of disease (rs=−0.10, p=0.54). Conclusion Based on the previous studies this is highly suspected that vitamin D would be a prominent factor in acne patients and more performances with bigger sample size could be useful to get positive results.

    The effect of gestodene 75 micrograms (GTD) versus desogestrel 150 micrograms (DSG) combined with 30 micrograms of ethinylestradiol (EE) on acne lesions and plasma androstenedione (A), total testosterone (T), sex hormone binding globulin (SHBG) and "free androgen index" (FAI) was evaluated in an open study on 19 patients aged 18-35 years affected with postpubertal or persistent non-severe acne vulgaris. The patients were randomly allocated into two groups receiving EE-GTD (n = 8) and EE-DSG (n = 11), 21 tablets per cycle for 9 consecutive cycles. Clinical and hormonal evaluations were made between days 17-21 in the cycle before treatment and between days 17-21 of the cycle 3, 6 and 9 of treatment. During treatment, acne improved in most patients, reaching at cycle 9 a low score (absent or minimal) in 62% of the cases in the GTD group (mean acne score = 1.25) and in 90% of the cases in the DSG group (mean acne score = 0.90). Before treatment, about 75% of the patients showed one or more signs of biochemical hyperandrogenism, including elevated FAI (57%), elevated A (15%), elevated total T (15%) and decreased SHBG (21%), and there was evidence of inverse correlation between SHBG and acne scores (p < 0.05). The echogenic texture of the ovaries was multifollicular in 55% of the cases. By the end of the third cycle of treatment, the hormonal changes observed in both groups included significant decreases, with normalization of individual elevated levels of T, and a 3-fold rise of the initial values of plasma SHBG, which showed a further gradual increase at cycle 9 of EE-DSG administration. At cycle 9, normalization of the echogenic ovarian texture was observed. Acne improvement under treatments with estrogen and progestin (EP) could be significantly correlated with the normalization of biochemical hyperandrogenism. In conclusion, the biochemical and clinical efficacy of EE-GTD and EE-DSG indicate that both these preparations can be a good choice in the therapy of acne

    Acne vulgaris is a very common facial skin disorder accounting for approximately 10 percent of all visits to ambulatory dermatology practices across the United States annually. Over time, greater attention has been directed to the roles of multiple epidermal barrier functions in various dermatological disorders, especially the stratum corneum permeability barrier and antimicrobial barrier. As a result, it has become readily apparent that professional direction of skin care is very important in the overall management of acne vulgaris. This article discusses several reasons that support the importance of incorporating specified skin care recommendations and instructions into the overall management plan for acne vulgaris. In addition, the article reviews formulation characteristics and some of the scientific data on two commercially available products that are recommended for use as a skin care regimen in patients with acne-prone and acne-affected skin, a foam wash and a moisturizer with a sun protection factor 30 broad spectrum photoprotection rating. The rationale for inclusion of specific ingredients are discussed along with an overview of research results including use in patients with acne vulgaris. PMID:24765221

    IMPORTANCE Effective patient education is necessary for treating patients with acne vulgaris. Automated online counseling simulates face-to-face encounters and may be a useful tool to deliver education. OBJECTIVE To compare the effectiveness of a standard educational website with that of an automated-counseling website in improving clinical outcomes and quality of life among adolescents with acne. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial conducted between March 27, 2014, and June 27, 2014, including a 12-week follow-up in a local inner-city high school. Ninety-eight students aged at least 13 years with mild to moderate acne were eligible for participation. A per-protocol analysis of the evaluable population was conducted on clinical outcome data. INTERVENTIONS Participants viewed either a standard educational website or an automated-counseling website. MAIN OUTCOMES AND MEASURES The primary outcome was the total acne lesion count. Secondary measures included the Children’s Dermatology Life Quality Index (CDLQI) scores and general skin care behavior. RESULTS Forty-nine participants were randomized to each group. At baseline, the mean (SD) total acne lesion count was not significantly different between the standard-website group and the automated-counseling–website group (21.33 [10.81] vs 25.33 [12.45]; P = .10). Improvement in the mean (SD) acne lesion count was not significantly different between the standard-website group and the automated-counseling–website group (0.20 [9.26] vs 3.90 [12.19]; P = .10). The mean (SD) improvement in CDLQI score for the standard-website group was not significantly different from that of the automated-counseling–website group (0.17 [2.64] vs 0.39 [2.94]; P = .71). After 12 weeks, a greater proportion of participants in the automated-counseling–website group maintained or adopted a recommended anti-acne skin care routine compared with the standard-website group (43% vs 22%; P = .03).

    Proper skin care is considered to be an important component of the total management plan for patients with acne vulgaris. A 28-day, open-label study provided both practical and scientific information on a designated skin care regimen in subjects with acne vulgaris. The cutaneous tolerability overall performance, and assessment of objective parameters evaluating the epidermal permeability barrier were documented with use of a specific foaming skin cleanser and a moisturizer with an SPF 30 broad spectrum rating in actively treated subjects with acne vulgaris. The results were favorable overall with the regimen shown to be nonirritating based on investigator and subject assessments, with high subject satisfaction and cosmetic acceptability ratings reported for both the foaming skin cleanser and the moisturizer with an SPF 30 broad spectrum rating. Objective instrumental testing of transepidermal water loss and epidermal hydration support that this skin care regimen assists in correcting epidermal permeability barrier dysfunctions that are innately present in acne vulgaris, worsened during a flare, and are known to be associated with many medications used to treat acne vulgaris. The recommendation of a specified skin care regimen incorporated into the overall management of acne vulgaris simplifies and standardizes the program for the patient, demonstrates a high level of interest by the clinician, and reduces the risk of the patient self-acquiring facial skin care products that may increase skin irritation.

    An 18-year-old Japanese girl had received oral minocycline 200mg daily for treatment of acne vulgaris since 16 years old. She had a fever three months before admission, followed by joint pains in her knees, elbows and several proximal interphalangeal joints one month before admission. She was referred to our hospital because of a high serum level of anti-DNA antibody. She had already discontinued oral minocycline five weeks before admission, because she missed her medication refilled. On admission, the arthralgia and fever spontaneously resolved, and there were no laboratory evidence of hypocomplementemia and cytopenia. She had neither erythema nor internal organ involvements. Because her symptoms subsided spontaneously after the cessation of minocycline, she was considered to have drug-induced lupus. Both the arthralgia and fever did not relapse, and anti-ds DNA antibody returned to normal during a follow-up period without treatment. There are few reports of drug-induced lupus caused by minocycline in Japan. This case highlights the importance of considering minocycline-induced lupus.

    Introduction Acne vulgaris is the most frequently diagnosed dermatosis in patients aged between 11 and 30. It is believed that it affects about 80% of persons in this age group or even, taking into account lesions of low intensity, 100% of young people. The role of cytokines in the pathogenesis of acne is not fully known. The TLR2 receptors play a role in the aetiology of acne. Stimulation of TLR2 by Propionibacterium acnes makes the IL-8 and IL-12 concentrations increase. Aim The aim of this work was to determine IL-1β, IL-1α, IL-8 and TNF-α levels in patients’ sera used to test response to TLR2 stimulation. A decrease in the levels of the above mentioned cytokines together with a decrease in sebum production were defined as an indication of efficient treatment with isotretinoin. Material and methods The tests were performed in 155 patients treated for different clinical forms of acne with an oral isotretinoin preparation in the Dermatology Clinic of the Silesian Medical University in Katowice in 2009–2011 – I group and the patients treated with oral isotretinoin 2 and 5 years ago – II group. The control group consisted of 40 healthy individuals. Conclusions Measurements of IL-1α, IL-1β and TNF-α sera concentrations could be assessed in parallel to the improvement of the clinical condition and can constitute a good indication of the efficiency of the isotretinoin treatment.

    Acne vulgaris is a skin disorder of the sebaceous follicles that commonly occurs in adolescence and in young adulthood. The major pathogenic factors involved are hyperkeratinization, obstruction of sebaceous follicles resulting from abnormal keratinization of the infundibular epithelium, stimulation of sebaceous gland secretion by androgens, and microbial colonization of pilosebaceous units by Propionibacterium acnes, which promotes perifollicular inflammation. The clinical presentation of acne can range from a mild comedonal form to severe inflammatory cystic acne of the face, chest, and back. At the ultrastructural level, follicular keratinocytes in comedones can be seen to possess increased numbers of desmosomes and tonofilaments, which result in ductal hypercornification. The increased activity of sebaceous glands elicited by androgen causes proliferation of P. acnes, an anaerobe present within the retained sebum in the pilosebaceous ducts. The organism possesses a ribosome-rich cytoplasm and a relatively thick cell wall, and produces several biologically active mediators that may contribute to inflammation, for instance, by promoting leukocyte migration and follicular rupture. In inflamed lesions, numerous neutrophils and macrophages infiltrate around hair follicles and sometimes phagocytose P. acnes. To examine the participation of neurogenic factors in the pathogenesis of acne, we quantitatively assessed the effects of neuropeptides on the morphology of sebaceous glands in vitro using electron microscopy. Substance P, which can be elicited by stress, promoted the development of cytoplasmic organelles in sebaceous cells, stimulated sebaceous germinative cells, and induced significant increases in the area of sebaceous glands. It also increased the size of individual sebaceous cells and the number of sebum vacuoles for each differentiated sebaceous cell, all of which suggests that substance P promotes both the proliferation and the differentiation of sebaceous

    Spironolactone (SP) known as an anti-androgen drug, has been proven to be effective in treatment of acne. The quest to minimize the unnecessary systemic side effects associated with the oral drug administration of spironolactone, has led to a growing interest of loading SP on lipid nanoparticles to deliver the drug in a topical formulation. The aim of the current investigation was to prepare and compare the performance of SP loaded nanostructured lipid carrier (SP-NLC) and SP alcoholic gels (SP-ALC) on two groups of respective patient populations, group A and group B in the treatment of mild to moderate acne vulgaris. The results showed that SP-NLCs were spherical in shape with an average diameter of ∼240nm. The polydispersity index (PI) and zeta potential of these nanoparticles were 0.286 and -21.4 respectively. The gels showed non-Newtonian independent pseudoplastic and shear thinning behavior. The SP-NLCs was not toxic to fibroblast cell strains at the 24 and 48h periods. Results showed that the mean number of total lesions (37.66±9.27) and non-inflammatory lesions (29.26±7.99) in group A significantly decreased to 20.31±6.58 (p<0.05) and to 13.95±5.22 (p<0.05) respectively. A similar pattern was observed for group B where the mean number of total lesions and non-inflammatory lesions reduced from 33.73±9.40 to 19.13±5.53 (p<0.05) and from 25.65±8.12 to 13.45±4.48 (p<0.05) respectively. The total lesion count (TLC) was significantly decreased from 37.16±9.28 to 19.63±6.36 (for group A; p<0.071) and 32.60±9.32 to 18.33±5.55 (for group B; p<0.05) respectively. After treatment with SP-NLC for 8 weeks, the water content of the skin significantly (p<0.05) increased from 37.44±8.85 to 45.69±19.34 instrumental units. Therefore, the SP-NLC gel may help in controlling acne vulgaris with skin care benefits.

    Acne is one of the most common skin diseases in the general population, especially among adolescents. Acne tarda (adult acne) is defined as acne that develops (late-onset acne) or continues (persistent acne) after 25 years of age. The disease is more common in women. The clinical features are quite specific: inflammatory acne in the lower facial region or macrocomedones (microcysts) spread over the face. Involvement of the trunk is much more common in men. The etiology of acne tarda is still controversial, as cosmetics, drugs, smoking, stress, diet, and endocrine abnormalities have been implicated. Women with acne tarda and other symptoms of hyperandrogenism have a high probability of endocrine abnormalities such as polycystic ovary syndrome. Treatment is similar to that of acne in adolescence. Long-term treatment over years or decades may be required.

    A placebo-controlled, randomized, double-blind, parallel-group, comparative, multicenter study was conducted to investigate the efficacy and safety of benzoyl peroxide (BPO) gel, administrated once daily for 12 weeks to Japanese patients with acne vulgaris. Efficacy was evaluated by counting all inflammatory and non-inflammatory lesions. Safety was evaluated based on adverse events, local skin tolerability scores and laboratory test values. All 609 subjects were randomly assigned to receive the study products (2.5% and 5% BPO and placebo), and 607 subjects were included in the full analysis set, 544 in the per protocol set and 609 in the safety analyses. The median rates of reduction from baseline to the last evaluation of the inflammatory lesion counts, the primary end-point, in the 2.5% and 5% BPO groups were 72.7% and 75.0%, respectively, and were significantly higher than that in the placebo group (41.7%). No deaths or other serious adverse events were observed. The incidences of adverse events in the 2.5% and 5% BPO groups were 56.4% and 58.8%, respectively; a higher incidence than in the placebo group, but there was no obvious difference between the 2.5% and 5% BPO groups. All adverse events were mild or moderate in severity. Most adverse events did not lead to study product discontinuation. The results suggested that both 2.5% and 5% BPO are useful for the treatment of acne vulgaris.

    Acne vulgaris, the most common disease of the skin, can be manifested in a wide variety of clinical presentations. As a result of this clinical variation, there are almost as many classifications of acne as there are clinicians with particular interest in the disease. Thus acne has been classified as types I-IV, inflammatory versus noninflammatory, comedonal, comedopapular, papular, papulopustular, pustular, and "cystic" or nodular (even nodular-cystic). For those who are enamored of classification, there are subdivisions of the various categories, including "sandpaper comedones" and microcysts. There is even disagreement as to what constitutes a papule versus a nodule. The classic textbook definition of a nodule refers to lesions 1 cm or larger, but the early investigators of oral isotretinoin defined nodules as 4 mm or larger, and this definition has creeped into many texts, recently clarified by Bologna.(1)

    Background The role of dietary factors in the pathophysiology of acne vulgaris is highly controversial. Hence, the aim of this study was to determine the association between dietary factors and acne vulgaris among Malaysian young adults. Methods A case–control study was conducted among 44 acne vulgaris patients and 44 controls aged 18 to 30 years from October 2010 to January 2011. Comprehensive acne severity scale (CASS) was used to determine acne severity. A questionnaire comprising items enquiring into the respondent’s family history and dietary patterns was distributed. Subjects were asked to record their food intake on two weekdays and one day on a weekend in a three day food diary. Anthropometric measurements including body weight, height and body fat percentage were taken. Acne severity was assessed by a dermatologist. Results Cases had a significantly higher dietary glycemic load (175 ± 35) compared to controls (122 ± 28) (p < 0.001). The frequency of milk (p < 0.01) and ice-cream (p < 0.01) consumptions was significantly higher in cases compared to controls. Females in the case group had a higher daily energy intake compared to their counterparts in the control group, 1812 ± 331 and 1590 ± 148 kcal respectively (p < 0.05). No significant difference was found in other nutrient intakes, Body Mass Index, and body fat percentage between case and control groups (p > 0.05). Conclusions Glycemic load diet and frequencies of milk and ice cream intake were positively associated with acne vulgaris. PMID:22898209

    BACKGROUND The current options for the treatment of acne vulgaris present many mechanisms of action. For several times, dermatologists try topical agents combinations, looking for better results. OBJECTIVES To evaluate the efficacy, tolerability and safety of a topical, fixed-dose combination of adapalene 0.1% and benzoyl peroxide 2.5% gel for the treatment of acne vulgaris in the Brazilian population. METHODS This is a multicenter, open-label and interventionist study. Patients applied 1.0 g of the fixed-dose combination of adapalene 0.1% and benzoyl peroxide 2.5% gel on the face, once daily at bedtime, during 12 weeks. Lesions were counted in all of the appointments, and the degree of acne severity, overall improvement, tolerability and safety were evaluated in each visit. RESULTS From 79 recruited patients, 73 concluded the study. There was significant, fast and progressive reduction of non-inflammatory, inflammatory and total number of lesions. At the end of the study, 75.3% of patients had a reduction of >50% in non-inflammatory lesions, 69.9% in inflammatory lesions and 78.1% in total number of lesions. Of the 73 patients, 71.2% had good to excellent response and 87.6% had satisfactory to good response. In the first week of treatment, erythema, burning, scaling and dryness of the skin were frequent complaints, but, from second week on, these signals and symptoms have reduced. CONCLUSION The fixed-dose combination of adapalene 0.1% and benzoyl peroxide 2.5% gel is effective, safe, well tolerated and apparently improves patient compliance with the treatment. PMID:27168522

    An open-label, randomized, multicenter study was conducted to evaluate the safety and efficacy of long-term use of 2.5% and 5% benzoyl peroxide (BPO) gels administrated once daily for 52 weeks to Japanese patients with acne vulgaris. The efficacy of the study drugs was evaluated by counting inflammatory lesions and non-inflammatory lesions. Safety was evaluated based on adverse events, local skin tolerability scores and laboratory test values. In total, 458 subjects were included in the efficacy and safety analyses. The total lesion count, the efficacy end-point, was similarly changed both in the 2.5% and 5% BPO groups over the course of the study. The median rates of reduction from baseline to week 12 were approximately 65%. Thereafter, the counts were maintained at a reduced level without increasing until week 52. The median rates at week 52 were approximately 80%. Similar trends were observed for inflammatory and non-inflammatory lesion counts. Bacteriological evaluation indicated similar distribution of the minimum inhibitory concentration of each of the antibacterial drugs against Propionibacterium acnes between the values at baseline and at week 52, suggesting that long-term use did not result in changes in the drug sensitivity. The incidence of adverse events was 84.0% in the 2.5% BPO group and 87.2% in the 5% BPO group. Many of the adverse events occurred within the first month and were mild or moderate in severity and transient. The results suggest that both 2.5% and 5% BPO gels are effective and safe for long-term treatment of patients with acne vulgaris.

    Background To treat moderate to severe acne vulgaris, we developed an optical fiber imported intra-tissue photodynamic therapy: the optical fiber irradiation 5-aminolevulinic acid photodynamic therapy (OFI-ALA-PDT). The aim of this study was to compare the treatment effect and tolerability of OFI-ALA-PDT versus traditional ALA-PDT in the treatment of moderate to severe acne vulgaris. Material/Methods 60 patients with facial acne enrolled into this study were randomly divided into an OFI-ALA-PDT group and a traditional ALA-PDT group, with 30 patients in each group. The difference between these 2 groups was the red light irradiation methods used. In the OFI-ALA-PDT group we used intra-tissue irradiation (import the red light directly into the target lesion with optical fiber) for 5 min, while the traditional ALA-PDT group received whole-face irradiation for 20 min. All patients received 1 irradiation every 7 to 10 days for a total of 6 irradiations. Treatment effects and adverse reactions were recorded after the 4th and 6th irradiation, and at 4, 8, 16 weeks after the entire treatment. Results After the 4th irradiation, significantly different effective rates were observed in these groups (90.0% for the OFI-ALA-PDT group and 66.7% for the control group). However, no significant difference in effective rate was recorded in the later observations. There were 182 adverse reactions in the OFI-ALA-PDT group and 497 in the control group, which showed a significant difference (P<0.05). Conclusions OFI-ALA-PDT showed improved treatment effective rate in the early stage of irradiation, and it had fewer adverse reactions. PMID:26839152

    BACKGROUND Based on personal observations of dermatologists, nutritionists and patients, a new problem emerges in the gyms: development and exacerbation of acne in users of whey protein, which is a protein derived from cow's milk. Whey Protein extract contains growth factors that may be related to acne. Its purity and composition are not fully known and there is no scientific research on its potential to cause acne. OBJECTIVES Assess the relationship between the use of proteincalorie supplements and onset or exacerbation of acne vulgaris in young adults in the city of João Pessoa. METHODS Descriptive observational study conducted in gyms and in a dermatology clinic. Each participant was examined for acne on three occasions and followed for 60 days. RESULTS 30 patients were examined. Onset or exacerbation of acneiform lesions were observed (p <0.0005). The effect was more prominent in females and in individuals without current acne and no family history of acne. CONCLUSION This study showed the onset of acne with the progressive use of protein-calorie supplementation, in a two-month period. It is suggested that this type of supplementation be discouraged.

    Acne vulgaris is a common chronic inflammatory cutaneous disease involving the pilosebaceous unit. Its pathophysiology is multifactorial and complex, including obstruction of the pilosebaceous unit due to increased sebum production, abnormal keratinization, proliferation of Propionibacterium acnes (P. acnes), and inflammation. Topical agents are the most commonly used therapy for acne. First generation topicals mainly consist of single agent retinoids, benzoyl peroxide (BPO) and antibacterials that target comedones, P. acnes, and inflammation. Novel topical therapies include combination products with advanced vehicle formulations that target multiple acne pathophysiologies and offer simplified treatment regimes. For example, the combination of clindamycin and tretinoin in a unique vehicle formulation allows for progressive follicle penetration and decreased irritation, resulting in increased efficacy. Furthermore, adapalene or clindamycin with BPO combinations target comedones, inflammation, and P. acnes synergistically. These newer combination products have the potential to increase both efficacy and patient adherence when compared with single agent treatment.

    Background Propionibacterium acnes (P. acnes) is an anaerobic, Gram-positive bacteria encountered in inflammatory acne lesions, particularly in the pilosebaceous follicle. P. acnes triggers a strong immune response involving keratinocytes, sebocytes and monocytes, the target cells during acne development. Lipoteicoic acid and peptidoglycan induce the inflammatory reaction, but no P. acnes surface protein interacting with Toll-like receptors has been identified. P. acnes surface proteins have been extracted by lithium stripping and shown to induce CXCL8 production by keratinocytes. Methodology and principal findings Far-western blotting identified two surface proteins, of 24.5- and 27.5-kDa in size, specifically recognized by TLR2. These proteins were characterized, by LC-MS/MS, as CAMP factor 1 devoid of its signal peptide sequence, as shown by N-terminal sequencing. Purified CAMP factor 1 induces CXCL8 production by activating the CXCL8 gene promoter, triggering the synthesis of CXCL8 mRNA. Antibodies against TLR2 significantly decreased the CXCL8 response. For the 27 P. acnes strains used in this study, CAMP1-TLR2 binding intensity was modulated and appeared to be strong in type IB and II strains, which produced large amounts of CXCL8, whereas most of the type IA1 and IA2 strains presented little or no CAMP1-TLR2 binding and low levels of CXCL8 production. The nucleotide sequence of CAMP factor displays a major polymorphism, defining two distinct genetic groups corresponding to CAMP factor 1 with 14 amino-acid changes from strains phylotyped II with moderate and high levels of CAMP1-TLR2 binding activity, and CAMP factor 1 containing 0, 1 or 2 amino-acid changes from strains phylotyped IA1, IA2, or IB presenting no, weak or moderate CAMP1-TLR2 binding. Conclusions Our findings indicate that CAMP factor 1 may contribute to P. acnes virulence, by amplifying the inflammation reaction through direct interaction with TLR2. PMID:27902761

    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.

  13. Acne vulgaris, probiotics and the gut-brain-skin axis - back to the future?

    PubMed Central

    2011-01-01

    Over 70 years have passed since dermatologists John H. Stokes and Donald M. Pillsbury first proposed a gastrointestinal mechanism for the overlap between depression, anxiety and skin conditions such as acne. Stokes and Pillsbury hypothesized that emotional states might alter the normal intestinal microflora, increase intestinal permeability and contribute to systemic inflammation. Among the remedies advocated by Stokes and Pillsbury were Lactobacillus acidophilus cultures. Many aspects of this gut-brain-skin unifying theory have recently been validated. The ability of the gut microbiota and oral probiotics to influence systemic inflammation, oxidative stress, glycemic control, tissue lipid content and even mood itself, may have important implications in acne. The intestinal microflora may also provide a twist to the developing diet and acne research. Here we provide a historical perspective to the contemporary investigations and clinical implications of the gut-brain-skin connection in acne. PMID:21281494

    Optimal management of acne vulgaris requires incorporation of several components including patient education, selection of a rational therapeutic regimen, dedicated adherence with the program by the patient, and integration of proper skin care. Unfortunately, the latter component is often overlooked or not emphasized strongly enough to the patient. Proper skin care may reduce potential irritation that can be associated with topical acne medications and prevents the patient from unknowingly using skin care products that can actually sabotage their treatment. This article reviews the effectiveness, skin tolerability, safety, and patient satisfaction of an open label study in which a specified skin care regimen is used in combination with topical therapy. The study was designed to mirror “real world” management of facial acne vulgaris clinical practice. The skin care regimen used in this study included a brand foam wash and a brand moisturizer with SPF 30 photoprotection, both of which contain ingredients that are included to provide benefits for acne-prone and acne-affected skin.

    Acne vulgaris is a common disease of the pilosebaceous unit and affects adolescents and adults. Because high-quality guidelines regarding treatment of acne in pregnancy are scarce, management of this condition can be challenging. We describe the safety profile of common therapies and outline approaches based on available evidence. Topical azelaic acid or benzoyl peroxide can be recommended as baseline therapy. A combination of topical erythromycin or clindamycin with benzoyl peroxide is recommended for inflammatory acne. Oral erythromycin or cephalexin is generally considered safe for moderate to severe inflammatory acne when used for a few weeks. A short course of oral prednisolone may be useful for treating fulminant nodular cystic acne after the first trimester. In general, topical and oral antibiotics should not be used as monotherapy, but combined with topical benzoyl peroxide to decrease bacterial resistance. Oral retinoids are teratogenic and absolutely contraindicated for women who are pregnant or considering pregnancy. Although some complementary therapies including micronutrients and nonpharmacologic treatments seem to be well tolerated, limited data exist regarding their safety and efficacy, and they are not currently recommended during pregnancy. The risk-to-benefit ratio, efficacy, acceptability, and costs are considerations when choosing a treatment for acne in pregnancy.

    Acne vulgaris significantly affects patients' quality of life (QOL) and their lives in various ways, including social behavior and body dissatisfaction. This may be heightened by acne's typical involvement of the face. We investigated whether the use of skin care and makeup could influence the QOL of affected patients without deteriorating conventional acne treatments. Fifty female patients with acne were recruited for our study. Twenty-five patients were instructed how to use skin care and cosmetics, while 25 patients received no specific instructions from dermatologists. Both groups received conventional topical and/or oral medication for acne during the study period for 4 weeks. Both groups did not show any significant difference in clinical improvement of acne severity. Two validated QOL questionnaires, World Health Organization (WHO)QOL26 and the Dermatology Life Quality Index (DLQI) were administered to all patients at first visit and 4 weeks later. The mean scores of psychological and overall domains in WHOQOL26 for patients with instructions were improved significantly, while only the overall score was significantly improved for patients without instructions. The total mean scores and all domains except work/school in DLQI for patients with instructions were improved significantly, while the total scores and all domains except discomfort for treatment in DLQI were significantly improved for patients without instructions. Thus, instructions on the use of skin care and cosmetics for female acne patients did not deteriorate acne treatment and influenced patients' QOL effectively. We therefore suggest that instructions for using skin care and cosmetics complement conventional medical treatments for acne.

    Current concepts of testosterone metabolism in the human skin are reviewed, and the role of dihydrotestosterone in the pathophysiology of androgenetic alopecia, acne vulgaris, and idiopathic hirsutism is discussed. The hypothesis is submitted that a temporary, increased dihydrotestosterone formation at specific skin target sites at different ages causes the normal development of certain sexual characteristics, as well as the androgen-dependent skin disorders. Future treatment of these conditions is discussed in light of recent studies with antiandrogens.

    Acne is a very common dermatosis with characteristic clinical features. It is a polymorphic disease. The clinical expression ranges from non-inflammatory closed and open comedones to inflammatory papules, pustules, and nodules. Most patients have a mixture of non-inflammatory and inflammatory lesions, although some have predominantly one or the other. Acne varies in severity from a very distressing, socially disabling disorder to a state that has been regarded as physiological by some authors. The most severe forms of acne are acne fulminans and acne inversa. Although acne may occur in all age groups, it is most prevalent during adolescence. It is not known why acne subsides in most patients but persists into adulthood in some. Certain medications may be associated with provocation, perpetuation, or exacerbation of pre-existing acne or with acneiform eruptions. Acne-like disorders include rosacea, pseudofolliculitis barbae, and other conditions that share clinical features with acne.

    2015-05-01

    Oral antibiotics have been used for the treatment of acne vulgaris for six decades. Among dermatologists, tetracyclines represent at least three-fourths of the oral antibiotics prescribed in clinical practice. Unlike other specialties, antibiotic use in dermatology is predominantly for the treatment of noninfectious disorders, such as acne vulgaris and rosacea, which usually involves prolonged therapy over several weeks to months as compared to short courses used to treat cutaneous infections. At the present time, doxycycline and minocycline are the most commonly prescribed tetracyclines in dermatology, used primarily for treatment of acne vulgaris with a long overall favorable track record of effectiveness and safety. Although both are commonly used, doxycycline may be chosen by clinicians more readily as there is a lower risk of rare yet potentially serious adverse reactions, although doxycycline does warrant preventative measures to reduce the risks of esophagitis and phototoxicity reactions. This article reviews data with a new double-scored small 150mg tablet of doxycycline hyclate that has proven functional scoring, exhibits bioavailability similar to enteric-coated doxycycline, and has been shown to be associated with a low potential for gastrointestinal adverse reactions very comparable to what is achieved with enteric-coated tablets.

    Context: Medical journals have allowed researchers to share their latest discoveries, especially in the most common diseases affecting patients worldwide. Objective: To analyze trends in the frequency of original research into common dermatologic diseases from 1970 to 2010. Design: A retrospective review of the Journal of the American Academy of Dermatology and the Archives of Dermatology was performed using the MEDLINE database. All original research articles published between 1970 and 2010, by quinquennium, dealing with acne vulgaris, rosacea, skin cancer, dermatitis, psoriasis, or skin infections were included. Main Outcome Measure: Total number of publications dealing with each dermatologic topic considered. Results: The frequency of research into acne vulgaris and rosacea decreased from 24% in 1970 to 5.1% in 2010. Psoriasis research increased in frequency from 17.6% to 26.5% from 2000 to 2010, and skin cancer research increased from 4% in 1970 to 48% in 2010. Conclusions: Topics that experienced early advancements in research, such as acne vulgaris and rosacea, demonstrated a decreasing trend in the frequency of publication. Published psoriasis research has increased in frequency since 2000, most likely because of the discovery of biologics. Finally, skin cancer research has continued to increase in frequency of publication, paralleling the increasing incidence of skin cancer. PMID:25663204

    Acne treatment by a mid-infrared laser may be unsatisfactory due to deeply situated acne-affected sebaceous glands which serve as its target. Skin manipulation by vacuum and contact cooling may improve laser-skin interaction, reduce pain sensation, and increase overall safety and efficacy. To evaluate the safety and efficacy of acne treatment using an integrated cooling-vacuum-assisted 1540-nm erbium:glass laser, a prospective interventional study was conducted. It included 12 patients (seven men and five women) suffering from mild-to-moderate acne vulgaris. The device utilizes a mid-infrared 1540-nm laser (Alma Lasers Ltd. Caesarea, Israel), which is integrated with combined cooling-vacuum-assisted technology. An acne lesion is initially manipulated upon contact by a vacuum-cooling-assisted tip, followed by three to four stacked laser pulses (500-600 mJ, 4 mm spot size, and frequency of 2 Hz). Patients underwent four to six treatment sessions with a 2-week interval and were followed-up 1 and 3 months after the last treatment. Clinical photographs were taken by high-resolution digital camera before and after treatment. Clinical evaluation was performed by two independent dermatologists, and results were graded on a scale of 0 (exacerbation) to 4 (76-100 % improvement). Patients' and physicians' satisfaction was also recorded. Pain perception and adverse effects were evaluated as well. All patients demonstrated a moderate to significant improvement (average score of 3.6 and 2.0 within 1 and 3 months, respectively, following last treatment session). No side effects, besides a transient erythema, were observed. Cooling-vacuum-assisted 1540-nm laser is safe and effective for the treatment of acne vulgaris.

    Systemic isotretinoin has been used to treat severe acne vulgaris for 20 years. However, isotretinoin also represents a potentially useful choice of drugs in many dermatologic diseases other than acne vulgaris. Diseases such as psoriasis, pityriasis rubra pilaris, condylomata acuminata, skin cancers, rosacea, hidradenitis suppurativa, granuloma annulare, lupus erythematosus and lichen planus have been shown to respond to the immunomodulatory, anti-inflammatory and antitumor activities of the drug. Isotretinoin also helps prevent skin cancers such as basal cell carcinoma or squamous cell carcinoma. A combination of systemic isotretinoin and interferon-alpha-2a may provide a more potent effect than isotretinoin alone in the prevention and treatment of skin cancers.Systemic isotretinoin may be considered as an alternative drug in some dermatologic diseases unresponsive to conventional treatment modalities. However, randomized clinical trials aimed at determining the role of systemic isotretinoin therapy in dermatologic diseases other than acne vulgaris are required.

    2003-01-01

    Acne vulgaris and rosacea present therapeutic challenges due to their chronicity, potential for disfigurement, and psychosocial impact. Although pathophysiologically distinct, both conditions have major inflammatory components. Consequently, topical and systemic antimicrobial agents are routinely prescribed for extended periods. Emergence of resistant strains of Propionibacterium acnes, adverse events, and compliance issues associated with chronic systemic tetracycline use have led to new treatment approaches. At subantimicrobial doses, tetracyclines reduce inflammation via anticollagenolytic, antimatrix-degrading metalloproteinase, and cytokine down-regulating properties. Subantimicrobial dose (SD) doxycycline (Periostat 20 mg) has clinical utility in periodontitis and has been investigated in a double-blind, placebo-controlled trial in the treatment of moderate facial acne as well as in an open label study in the treatment of rosacea. The results of subantimicrobial dose doxycycline treatment in early trials support its benefits and further investigation in acne and rosacea.

    The multiple etiologic factors involved in acne vulgaris make the use of several medications necessary to treat the condition. Use of a fixed combination of clindamycin phosphate 1.2% and tretinoin 0.025% in conjunction with a benzoyl peroxide (BPO) wash 4% targets several pathologic factors simultaneously and mitigates the potential for clindamycin-induced Propionibacterium acnes-resistant strains. New formulations may allow such regimens to be effectively used without overly reduced tolerability resulting from the irritation potential of tretinoin and BPO. This randomized, single-blind study investigated the local tolerability, irritation potential, and safety of an aqueous-based gel (clindamycin phosphate 7.2%-tretinoin 0.025% [CT gel]) when used in conjunction with a BPO wash 4% in participants with mild to moderate acne vulgaris. Participants applied the CT gel once daily in the evening for 4 weeks in conjunction with once-daily morning use of either BPO wash 4% or nonmedicated soap-free cleanser lotion (SFC). Local tolerability and irritation potential were assessed by participants and investigators using separate 6-point scales. The frequency and severity of dryness, scaling, erythema, burning/stinging, and itching increased during the first week of treatment in both treatment arms but decreased thereafter. Local tolerability reactions were slightly more frequent in the CT gel + BPO wash group versus the CT gel + SFC group at week 1 but were generally mild and improved within 1 to 2 weeks. In conclusion, therapy with CT gel + BPO wash appears safe and well-tolerated in participants with mild to moderate acne vulgaris.

    This study evaluated the antimicrobial activity of lauric acid (LA) and its liposomal derivatives against Propionibacterium acnes (P. acnes), the bacterium that promotes inflammatory acne. First, the antimicrobial study of three free fatty acids (lauric acid, palmitic acid and oleic acid) demonstrated that LA gives the strongest bactericidal activity against P. acnes. However, a setback of using LA as a potential treatment for inflammatory acne is its poor water solubility. Then the LA was incorporated into a liposome formulation to aid its delivery to P. acnes. It's demonstrated that the antimicrobial activity of LA was not only well maintained in its liposomal derivatives but also enhanced at low LA concentration. In addition, the antimicrobial activity of LA-loaded liposomes (LipoLA) mainly depended on the LA loading concentration per single liposomes. Further study found that the LipoLA could fuse with the membranes of P. acnes and release the carried LA directly into the bacterial membranes, thereby killing the bacteria effectively. Since LA is a natural compound that is the main acid in coconut oil and also resides in human breast milk and liposomes have been successfully and widely applied as a drug delivery vehicle in the clinic, the LipoLA developed in this work holds great potential of becoming an innate, safe and effective therapeutic medication for acne vulgaris and other P. acnes associated diseases.

A number of 20 patients with papular, pustular or nodular acne and another 20 patients with seborrheic dermatitis were available for our study. We removed bioptic material from all of them and we perform histochemical and immunohistochemical processing within the Laboratory of Histology, Histopathology and Immunohistochemistry of the University of Medicine and Pharmacy of Craiova. In acne, we could reveal a positive CD45.Ro immunomarking in rare lymphoid cells situated in the middle derma at a distance from the affected pilosebaceous follicle and in the inflammatory infiltrate subepidermically, and also a negative immunomarking in the inflammatory cells from the proximity of the affected pilosebaceous follicle. In patients with seborrheic dermatitis we noticed a positive immunomarking infiltrate of the papillary derma and a positive immunomarking of membrane for CD45.Ro in many lymphoid cells of the inflammatory infiltrate situated in the papillary derma predominantly disposed perivasculary. Conclusions. The absence of the cells marked with CD45.Ro in the proximity of the pilosebaceous follicle interested in acne excludes the direct participation of B- and T-lymphocytes in the perifollicular inflammatory process, though the T-lymphocytes can be revealed in a small number at a distance from the affected follicle. The inflammatory infiltrate from the seborrheic dermatitis proved to be rich in positive CD45.Ro cells and poorer in positive CD20 cells.

    Objective: To assess the effect of chocolate on acne exacerbation in males between the ages of 18 and 35 with a history of acne vulgaris. Design: Double-blind, placebo-controlled, randomized, controlled trial. Setting: Single-site, outpatient, research, clinical facility at an academic research institution. Participants: Fourteen men between the ages of 18 and 35 were assigned to swallow capsules filled with either unsweetened 100-percent cocoa, hydrolyzed gelatin powder, or a combination of the two, at baseline. Measurements: Lesions were assessed and photographs were taken at baseline, Day 4, and Day 7. Results: Of the 14 subjects, 13 completed this Institutional Review Board approved study. A statistically significant increase in the mean number of total acneiform lesions (comedones, papules, pustules, nodules) was detected on both Day 4 (p=0.006) and Day 7 (p=0.043) compared to baseline. A small-strength positive Pearson’s correlation coefficient existed between the amount of chocolate each subject consumed and the number of lesions each subject developed between baseline and Day 4 (r=0.250), while a medium-strength positive correlation existed between baseline and Day 7 (r=0.314). No serious adverse events occurred. Conclusion: It appears that in acne-prone, male individuals, the consumption of chocolate correlates to an increase in the exacerbation of acne. PMID:24847404

    Aminolevulinic acid (ALA) photodynamic therapy (PDT) is an emerging modality in the treatment of acne. While ablative fractional lasers have been used to enhance drug delivery into the epidermis, recent evidence suggests that non-ablative fractional photothermolysis may also improve uptake of ALA. We explored the use of non-ablative 1550 nm laser as a safe alternative in the delivery of ALA prior to red-light PDT for refractory inflammatory and cystic acne. Subjects referred for treatment of acne refractory to several topical and oral regimens, including isotretinoin, were pre-treated with non-ablative fractional photothermolysis (NAFP). This was followed by 20 % ALA application with an incubation time of 1-3 h and then exposure to 50-100 J/cm(2) red light. Follow-up was at 1, 3, and 6 months. In all three cases, patients demonstrated marked reduction in inflammatory lesions. Two subjects had remission of acne after a single combination treatment. Non-ablative fractional laser applied immediately prior to PDT may be used in the treatment of acne with minimal side effects and fewer sessions needed than PDT alone. This may be due to enhanced delivery of ALA from pre-treating the skin with non-ablative fractional photothermolysis.

    Introduction Acne vulgaris is a common chronic inflammatory disease of the pilosebaceous unit triggered by Propionibacterium acnes. A bakuchiol, Ginkgo biloba extract, and mannitol (BGM) complex has been developed to provide patients with acne with a specific dermocosmetic to be used adjunctively with conventional treatments. Objective The aim of these studies was to assess the antibacterial, anti-inflammatory, and antioxidative potential of BGM complex and its individual compounds as well as its impact on sebum composition. Methods The antibacterial, anti-inflammatory, and antioxidative potential of BGM complex and its compounds was assessed through in vitro, ex vivo, and clinical studies. The clinical benefit of BGM complex formulated in a cream was assessed in subjects prone to acne through sebum composition analysis and photometric assessments. Results Results from the studies showed that the BGM complex has significant antibacterial, anti-inflammatory, and antioxidative properties. At similar concentrations, bakuchiol has up to twice the antioxidative potential than vitamin E. In subjects, BGM complex regulated the sebum composition in acne patients by increasing the level of sapienic and linolenic acid and reducing the level of oleic acid. The reduced number of porphyrins on the skin surface showed that it is also effective against P. acnes. Conclusion BGM complex provides a complete adjunctive care in patients with acne by targeting etiopathogenic factors of acne: dysseborrhea, inflammation, and P. acnes proliferation. PMID:27621660

    Popular brands of soaps and shampoos were assayed for comedogenicity in the rabbit ear. Only a small number produced hyperkeratosis when applied at a 25% concentration. Bacteriostatic substances, especially hexachlorophene, were mildly comedogenic. Conventional soaps include salts of fatty acids; the latter are known comedogens. The obsessive use of soaps by patients with acne vulgaris may aggravate the disease and result in its extension to unusual locations.

    Acne is the most common disease of the skin. It affects 85% of teenagers, 42.5% of men, and 50.9% of women between the ages of 20 and 30 years.96,97 The role of hormones, particularly as a trigger of sebum production and sebaceous growth and differentiation, is well known. Excess production of hormones, specifically androgens, GH, IGF-1, insulin, CRH, and glucocorticoids, is associated with increased rates of acne development. Acne may be a feature in many endocrine disorders, including polycystic ovary disease, Cushing syndrome, CAH, androgen-secreting tumors, and acromegaly. Other nonendocrine diseases associated with acne include Apert syndrome, SAPHO syndrome, Behçet syndrome and PAPA syndrome. Acne medicamentosa is the development of acne vulgaris or an acneiform eruption with the use of certain medications. These medications include testosterone, progesterone,steroids, lithium, phenytoin, isoniazid, vitamins B2, B6, and B12, halogens, and epidermal growth factor inhibitors. Management of acne medicamentosa includes standard acne therapy. Discontinuation of the offending drug may be necessary in recalcitrant cases. Basic therapeutic interventions for acne include topical therapy, systemic antibiotics,hormonal agents, isotretinoin, and physical treatments. Generally, the severity of acne lesions determines the type of acne regimen necessary. The emergence of drug-resistant P acnes and adverse side effects are current limitations to effective acne management.

    Isotretinoin is a revolutionary medicine for the treatment of acne vulgaris, with new studies showing evidence of excellent clinical outcomes in treating rosacea. After 30 years of clinical experience, new insights are being gained into dosing strategies, recurrence prevention, and dose-related side effects. Previous controversial associations with inflammatory bowel diseases and mood disorders have hampered the use of this medication in some clinical situations, with new evidence disproving these claims. The teratogenicity of this medication mandates iPLEDGE compliance with government regulations. Clinicians should be knowledgeable about this medication including its side effects, teratogenicity, and its controversies in order to adequately counsel patients, dissuade fears, and obtain the best clinical outcome when treating acne and rosacea.

    To clarify the relationship between major cutaneous microorganisms (Propionibacterium, Staphylococcus and Malassezia spp.) and acne vulgaris (acne), we examined the microbiota quantitatively in the follicular contents of inflammatory acne and on the facial skin of patients with acne. Fifteen Japanese untreated acne outpatients were studied. The follicular contents from inflammatory acne lesions of the face were collected using a comedo extractor. The skin surface samples were obtained by the swab method from 10 cm(2) of facial skin. The microbiota was analyzed using polymerase chain reaction. The microbiota in follicular contents was similar to that on the skin surface, namely, there were large populations of Propionibacterium spp., Staphylococcus spp. and Malassezia spp. Moreover, the number of Malassezia spp. on the skin surface was correlated with that of inflammatory acne and that in follicular contents. This study clarified that there are large populations of Propionibacterium spp., Staphylococcus spp. and Malassezia spp. in follicular contents. These results suggest the possibility that not only Propionibacterium acnes but also other cutaneous resident microorganisms are related to acne. Particularly, we considered that Malassezia spp. is closely related.

    Background The purpose of the current survey was to evaluate how teenagers and adults view teens with acne as compared to those with smooth, clear skin. We also surveyed teens and adults about their experiences with acne. Methods We hypothesized that teens with acne would be perceived in a more negative fashion as compared to teens with smooth, clear skin. We presented digitally altered photographs to our responders and asked how they perceived the two groups. No mention was made of acne. In the first survey (n = 1,002), both adults and teens provided their impressions on photo images of teenagers with either clear skin or acne. In the second survey (n = 1,006), the adults and teens also answered questions about their own experiences with acne. Results Survey 1. With respect to impressions of photo images, the first thing teens and adults noticed about a person with acne was their skin (65% and 75%, respectively). Teenagers with acne were perceived most often by other teens and adults (teen responder %, adult responder %) as being shy (39%, 43%), nerdy (31%, 21%), stressed (24%, 20%), lonely (23%, 22%), boring (15%, 6%), unkempt (13%, 7%), unhealthy (12%, 8%), introverted (9%, 23%), and rebellious (7%, 5%). Survey 2. Most teenagers with acne (64%) felt embarrassed by it and thought that getting acne was the most difficult aspect of puberty (55%). Teenagers with acne reported lower self-confidence or shyness (71%); difficulty finding dates (43%), problems making friends (24%), challenges with school (21%), and trouble getting a job (7%). Conclusions Teens with smooth, clear skin were rated higher on every favorable characteristic and lower on every unfavorable characteristic by both teens and adults. In most cases, the first thing that respondents noticed was the skin of teens with acne. Teenagers and adults alike perceived other teens with acne as generally being shy, less socially active, more likely to be bullied, and less successful in terms of finding a job

    The effects of chocolate on acne exacerbations have recently been reevaluated. For so many years, it was thought that it had no role in worsening acne. To investigate whether 99% dark chocolate, when consumed in regular daily amounts, would cause acne to worsen in acne-prone male subjects, twenty-five acne prone male subjects were asked to consume 25 g of 99% dark chocolate daily for 4 weeks. Assessments which included Leeds revised acne scores as well as lesion counts took place weekly. Food frequency questionnaire was used, and daily activities were recorded. Statistically significant changes of acne scores and numbers of comedones and inflammatory papules were detected as early as 2 weeks into the study. At 4 weeks, the changes remained statistically significant compared to baseline. Dark chocolate when consumed in normal amounts for 4 weeks can exacerbate acne in male subjects with acne-prone skin.

    The chemoattraction of Propionibacterium acnes lipase for neutrophils and the effect of lipase inhibitor and two antibiotic agents on the chemotaxis were evaluated. Of the various fractions tested, partially purified lipase (fraction 2c) was the most active cytotaxin produced by P. acnes. Serum mediators were not required for the generation of chemotaxis by lipase in vitro. Diisopropyl phosphofluoridate at low concentration (10(-4) mM) completely inhibited lipase activity as well as polymorphonuclear leukocyte chemotaxis generated by lipase. Tetracycline hydrochloride and erythromycin base at concentrations of 10(-1) mM and 1 mM, respectively, caused 100% inhibition of PMN migration toward lipase or zymosan-activated serum. The inhibiting activity of the antibiotics was directed against cells independently of any effect on lipase. Chemotaxis by P. acnes lipase suggests a wider role for this enzyme in the inflammatory process and the pathogenesis of acne vulgaris. Images PMID:7054130

    Objective: The aim of this study was to determine the in vitro anti-inflammatory activities of solvent fractions from Chlorella vulgaris by inhibiting the production of pro-inflammatory mediators and cytokines. Methods: Methanolic extracts (80%) of C. vulgaris were prepared and partitioned with solvents of increasing polarity viz., n-hexane, chloroform, ethanol, and water. Various concentrations of the fractions were tested for cytotoxicity in RAW 264.7 cells using 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, and the concentrations inducing cell growth inhibition by about 50% (IC50) were chosen for further studies. Lipopolysaccharide (LPS) stimulated RAW 264.7 cells were treated with varying concentrations of C. vulgaris fractions and examined for its effects on nitric oxide (NO) production by Griess assay. The release of prostaglandin E2 (PGE2), tumor necrosis factor-α (TNF-α), and interleukin 6 (IL-6) were quantified using enzyme-linked immunosorbent assay using Celecoxib and polymyxin B as positive controls. Results: MTT assay revealed all the solvent fractions that inhibited cell growth in a dose-dependent manner. Of all the extracts, 80% methanolic extract exhibited the strongest anti-inflammatory activity by inhibiting NO production (P < 0.01), PGE2 (P < 0.05), TNF-α, and IL-6 (P < 0.001) release in LPS induced RAW 264.7 cells. Both hexane and chloroform fractions recorded a significant (P < 0.05) and dose-dependent inhibition of LPS induced inflammatory mediators and cytokines in vitro. The anti-inflammatory effect of ethanol and aqueous extracts was not significant in the study. Conclusion: The significant inhibition of inflammatory mediators and cytokines by fractions from C. vulgaris suggests that this microalga would be a potential source of developing anti-inflammatory agents and a good alternate for conventional steroidal and nonsteroidal anti-inflammatory drugs.

    A 19-year-old Japanese man had been treated for ulcerative colitis for 2 years. He was admitted to our hospital with nodulocystic inflammatory papules and pustules on his face and chest, high-grade fever, arthralgia and general malaise. A biopsy specimen from a pustule showed prominent infiltration of neutrophils in the epidermis and dermis, particularly around hair follicles. We made a diagnosis of acne fulminans. The systemic administration of prednisolone at 30 mg daily for 1 week immediately improved his skin lesions and other symptoms; however, during tapering of prednisolone at 20 mg daily, skin lesions flared up. The addition of oral diaminodiphenylsulfone improved the skin lesions. Although there have been a few reports of acne fulminans associated with Crohn's disease, this is the first case report of acne fulminans in a patient with ulcerative colitis. It is noteworthy that the addition of diaminodiphenylsulfone was effective for treating the relapse of acne fulminans in this case.

    Thyme (Thymus vulgaris L., Lamiaceae) is an aromatic and medicinal plant that has been used in folk medicine, phytopharmaceutical preparations, food preservatives, and as an aromatic ingredient. The effect of Thymus vulgaris essential oil (TEO) and its isolated constituents thymol and cavacrol (CVL) were studied in the following experimental models: ear edema, carrageenan-induced pleurisy, and chemotaxis in vitro. In the pleurisy model, TEO, CVL, and thymol significantly inhibited inflammatory edema. However, only TEO and CVL inhibited leukocyte migration. In the in vitro chemotaxis experiment, CVL inhibited leukocyte migration, whereas thymol exerted a potent chemoattractant effect. In the ear edema model, CVL (10 mg/ear), applied topically, reduced edema formation, exerting a topical anti-inflammatory effect. Thymol did not reduce edema formation but rather presented an irritative response, probably dependent on histamine and prostanoid release. Our data suggest that the antiinflammatory effects of TEO and CVL are attributable to the inhibition of inflammatory edema and leukocyte migration. PMID:22919415

    Result of Monte Carlo simulations of skin optical clearing is presented. The model calculations were carried out with the aim of studying of spectral response of skin under immersion liquids action and calculation of enhancement of light penetration depth. In summary, we have shown that: 1) application of glucose, propylene glycol and glycerol produced significant decrease of light scattering in different skin layers; 2) maximal clearing effect will be obtained in case of optical clearing of skin dermis, however, absorbed light fraction in skin dermis changed insignificantly, independently on clearing agent and place it administration; 3) in contrast to it, the light absorbed fraction in skin adipose layer increased significantly in case of optical clearing of skin dermis. It is very important because it can be used for development of optical methods of obesity treatment; 4) optical clearing of superficial skin layers can be used for decreasing of power of light radiation used for treatment of acne vulgaris.

    We compared the efficacy and safety of lymecycline 300 mg od vs lymecycline 150 mg bid or placebo in the treatment of moderate to severe acne. 271 patients received either oral lymecycline 300 mg od + placebo od, lymecycline 150 mg bid, or placebo bid, for 12 weeks. Reduction in inflammatory lesion counts at week 12 was the primary efficacy variable (global improvement was a primary efficacy parameter vs placebo) and safety was assessed by adverse events. Lymecycline 300 mg od was non-inferior to lymecycline 150 mg bid at all time points and superior to placebo throughout the study. Drug-related adverse events were similar for all treatment groups. Lymecycline 300 mg od is as effective and safe as lymecycline 150 mg bid in the treatment of moderate to severe acne. This new, once daily formulation could potentially contribute towards improved compliance rates with oral tetracyclines.

    Androgens stimulate sebum production which is necessary for the development of acne. Acne in women may thus be considered as a manifestation of cutaneous androgenization. Most of acnes may be related to an idiopathic skin hyperandrogenism due to in situ enzyme activity and androgen receptor hypersensitivity, as also noted in idiopathic hirsutism. Some acne may correspond to elevated ovarian or adrenal androgen secretion. The presence of acne in women may lead to a diagnosis of functional hyperandrogenism, either polycysticovary syndrome or nonclassical 21-hydroxylase deficiency. Plasma level assays for testosterone, delta 4 androstenedione and 17-OH progesterone and ovarian echography are necessary to determine the possibility for an ovarian or adrenal hyperandrogenism, but not to better treat acne. The goal of hormonal therapy in acne is to oppose the effects of androgens on the sebaceous gland. Hormones may be used in female acne in the absence of endocrine abnormalities. Antiandrogens (cyproterone acetate or aldactone) may be useful in severe acne, hormonal contraceptives with cyproterone acetate or non androgenic progestins in mild or common acne often in association with other anti-acneic drugs. Glucocorticoids have to be administered in acne fulminans and other forms of acute, severe, inflammatory acne, for their anti-inflammatory properties.

    This 12-week, single-center, investigator-blinded, randomized, parallel-design study assessed the safety and efficacy of tretinoin microsphere gel 0.04% delivered by pump (TMG PUMP) to tazarotene cream 0.05% (TAZ) in mild-to-moderate facial acne vulgaris. Efficacy measurements included investigator global assessment (IGA), lesion counts, and subject self-assessment of acne signs and symptoms. Efficacy was generally comparable between treatment groups, although TMG PUMP provided more rapid results in several parameters. IGA showed a more rapid mean change from baseline at week 4 in the TMG PUMP group (-0.18 versus -0.05 in the TAZ subjects). TMG PUMP yielded more rapid improvement in papules. At week 4, the mean percentage change from baseline in open comedones was statistically significant at -64% in the TMG PUMP group (P=0.0039, within group) versus -19% in the TAZ group (not statistically significant within the group; P=0.1875). Skin dryness, peeling and pruritus were significantly less in the TMG PUMP group as early as week 4. Adverse events related to study treatment were rare in both groups and all resolved upon discontinuation of study medication.

    Acne vulgaris affects most people at some time in their life. This common condition can have devastating effects on a person's quality of life and may leave permanent scars. Treatment options, which are designed to disrupt one or more of the pathogenic features that characterize acne, include topical therapies (e.g., antibiotics, retinoids, benzoyl peroxide and combination products), systemic treatments (e.g., oral antibiotics, hormonal therapies and oral retinoids, which are indicated for severe recalcitrant nodulocystic acne), and, to a lesser extent, light-based and physical treatments. Combination oral contraceptives (COCs) represent one type of hormonal treatment. Their mode of action is to reduce the availability of free testosterone, which stimulates the sebaceous glands to produce sebum. Most COCs used in the United States contain progestins derived from 19-nortestosterone, giving them at least some degree of androgenic activity. Of the 3 COCs with an FDA indication for the treatment of moderate acne, only YAZ contains drospirenone, a progestin that combines no androgenic activity with antiandrogenic activity. This drospirenone-containing COC has been shown to be effective in reducing both inflammatory and noninflammatory acne lesions.

    The objective of this article is to investigate the effectiveness and safety of photodynamic therapy (PDT) with 3.6 % topical aminolevulinic acid (ALA) and a short incubation time with red light in moderate to severe acne. One hundred and thirty-six patients with moderate to severe acne were treated with 3.6 % topical ALA-PDT for three sessions with an interval of 2 weeks. Patients were evaluated for efficacy and safety on week 2, 4, 6, 8, and 12 after the initial treatment. Most patients showed apparent clearance of acne lesions at the treated site after three sessions. The effective treatment rates were increased after the multiple therapies. The clinical outcomes are the best at 4 weeks after the final treatment. The total effectiveness rate and cure rate of the low-dose ALA-PDT procedure is 92.65 and 47.06 %, respectively. Thirty-one patients and nineteen patients showed apparent exacerbation of acne lesions before the 2nd and 3rd treatment, respectively, but all of them showed good or excellent improvement after a three-course treatment. A few patients showed mild relapse including papules and comedos at 8 weeks after the final treatment. No significant differences are found in the effects of different acne severity and different genders. Adverse reactions are mild and transient. A 3.6 % topical ALA-PDT with a short time incubation with red light is a simple and an effective treatment option for moderate to severe acne with mild side effects in Chinese people.

    Twelve known triterpenoids (1-12) and two steroids (13 and 14) have been isolated from the spike of the plant Prunella vulgaris. Among them, 2α,3α,23-trihydroxyursa-12,20(30)-dien-28-oic acid (10) was isolated for the first time from this plant. All isolates were evaluated for their inhibitory effect on the gene expression of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), and release of histamine in human mast cells. β-Amyrin (5), 10, and euscaphic acid (12) showed suppression of histamine release with percentage inhibitions of 46.7, 57.9, and 54.2%, respectively. In addition, 5 and 10 showed strong inhibition of TNF-α and IL-6 in the test for pro-inflammatory cytokines. Our results suggest that compounds 5 and 10 largely contribute to the anti-allergic inflammatory effect of P. vulgaris.

    Photodynamic therapy (PDT), consisting of photosensitizer, light, and oxygen has been used for the treatment of various diseases including cancers, microbial infections and skin disorders. In this study, we examined the anti-inflammatory effect of chlorin e6-mediated PDT in P. acnes-infected HaCaT cells using photosensitizer chlorin e6 (Ce6) and halogen light. The live and heat-killed P. acnes triggered an upregulation of inflammatory molecules such as iNOS, NO, and inflammatory cytokine in HaCaT cells and mouse model. Ce6-mediated PDT notably downregulated the expression of these inflammatory molecules in vitro and in vivo. Similarly, chlorin e6-mediated PDT was capable of regulating inflammatory response in both live and heat killed S. epidermidis exposed HaCaT cells. Moreover, phosphorylation of p38, JNK, and ERK were reduced by Ce6-mediated PDT. Ce6-mediated PDT also reduced the phosphorylation of IKKα/β, IĸBα and NFκB p65 in P. acnes-stimulated HaCaT cells. In addition, the dramatic increase in the nuclear translocation of NFκB p65 observed upon stimulation with P. acnes was markedly impaired by Ce6-based PDT. This is the first suggestion that Ce6-mediated PDT suppresses P. acnes-induced inflammation through modulating NFκB and MAPKs signaling pathways. PMID:28118375

    Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive aged women. It is typically characterized by hyperandrogenism, chronic anovulation, and polycystic ovaries. Women with PCOS often experience dermatologic manifestations of hyperandrogenism, including hirsutism, acne vulgaris, and androgenic alopecia. This article will review the treatments for acne due to androgen excess in PCOS women.

    Objective. To evaluate the clinical benefit in adolescents of a three-step acne system containing solubilized benzoyl peroxide. Design. Patients in this multicenter, investigator-blind trial were randomly assigned to receive 10 weeks of treatment with either the three-step acne system for normal-to-oily skin (proprietary 2% salicylic acid cleanser twice daily + proprietary 2% salicylic acid toner once daily + solubilized 5% benzoyl peroxide gel twice daily) or with control cleanser + 5% benzoyl peroxide/1% clindamycin gel twice daily. Setting. Patients seeking acne treatment from a dermatologist. Pediatric subgroup analysis from a larger trial. Participants. Eighty-two adolescents with mild-to-moderate facial acne vulgaris. Measurements. Noninflammatory and inflammatory lesion counts, erythema, dryness, peeling, burning/stinging, and itching. Results. The three-step acne system was significantly more effective than benzoyl peroxide/clindamycin in reducing the noninflammatory lesion count at Weeks 2 and 4. The antibiotic-free acne system was also comparably effective to benzoyl peroxide/clindamycin in reducing the inflammatory lesion count at all timepoints. Both regimens were generally well tolerated with mean levels of erythema, dryness, peeling, burning/stinging, and itching less than mild in both groups at all timepoints. Conclusions. The three-step acne system is an effective antibiotic-free acne treatment. Relative to benzoyl peroxide/clindamycin, its ability to achieve comparable reductions in inflammatory lesions, and significantly greater reductions in noninflammatory lesions in the early weeks of treatment is likely attributable to the solubilization of the benzoyl peroxide enhancing the bioavailability and intrafollicular penetration of the benzoyl peroxide.

    The purpose of the present study was to investigate hypolipidemic and anti-inflammatory effects of Artemisia vulgaris extract in hypercholesterolemic rats. Hypercholesterolemia was induced by feeding of rats with high fat diet containing 3% cholesterol in olein oil, for 8 weeks. Feeding of rats with high fat diet for 8 weeks, leading to a significant increase in serum triglycerides, total cholesterol, low density lipoprotein cholesterol, malondialdehyde and nitric oxide, tumor necrosis factor-α levels and a significant decrease in serum high density lipoprotein cholesterol level, liver hydroxymethylglutaryl-CoA reductase activity and paraoxonase-1 activities as compared to the normal control group. Treatment of high fat diet rats with Artemisia vulgaris extract for 4 weeks at a dose of 100 mg/kg per day, resulted in normalized serum lipid profile, a significant increase in paraoxonase-1 activity and decrease in serum malondialdehyde, nitric oxide and tumor necrosis factor-α level as compared to high fat diet-treated animals. Also the extract caused a significant decrease in hydroxymethylglutaryl-CoA reductase activity as compared with both high fat diet-treated animals and control ones. In conclusion, Artemisia vulgaris extract has hypolipidemic, anti-inflammatory, antioxidant properties; it may serve as a source for the prevention of atherosclerosis and cardiovascular diseases.

    The time until a patient achieves a relevant improvement during the treatment of a skin disease is important for selecting a therapy, but has been largely neglected in reviews and guidelines. The aim of this systematic review was to determine the time until the onset of action (TOA) of topical acne treatments. The primary outcome was the TOA defined as the time until a 25% reduction in the mean number of inflammatory lesions had been achieved. A systematic literature search in Medline and Embase was carried out. Clinical trials that evaluated head-to-head comparisons of treatments in patients suffering from mild-to-moderate papulopustular acne were included. Abstract and full-text screening and data extraction were done independently by two investigators. With respect to inflammatory lesions, different concentrations of benzoyl peroxide (BPO) or adapalene did not seem to influence the TOA. BPO seemed to act more quickly than isotretinoin and tretinoin. Adapalene showed a shorter TOA than isotretinoin. Conflicting results were seen when comparing adapalene with tretinoin, with a tendency for adapalene to be faster. Clindamycin/BPO seemed to act more quickly than adapalene. Inconsistent results were seen for the comparison of clindamycin/BPO and BPO alone with a slight indication of a shorter TOA for clindamycin/BPO. Adapalene/BPO and clindamycin/BPO showed comparable TOA. When interpreting the data, the different study designs and the limited study quality need to be taken into account. Further research is needed to identify treatments that offer an early onset of action and possibly help to optimize patients' adherence. TOA should be considered as an additional outcome in acne trials.

    This review summarizes important clinical developments in acne vulgaris identified from 17 systematic reviews published between February 2011 and August 2012. Regarding causes, Demodex mites have been shown to be associated with both acne vulgaris and rosacea, although it is unclear if their eradication improves either disease. Some weak evidence has emerged that suggests a possible link between dairy produce and acne, which warrants further research. With reference to the effects of acne, there is good evidence that acne negatively affects quality of life, self-esteem and mood in adolescents. Acne is also associated with an increased risk of anxiety, depression and suicidal ideation, highlighting the importance of asking patients with acne directly about psychological issues in order to identify those who might benefit from early psychiatric support. Regarding treatment, there seems to be no additional benefit to using higher strengths of benzoyl peroxide, and lower strengths such as 2.5% have fewer side effects. Despite earlier concerns of increased mortality in those using topical tretinoin for skin cancer prevention, a systematic review on this topic has not found any convincing evidence of a link between such non-cutaneous events and once-daily application of 0.02-0.05% tretinoin. Combined oral contraceptives are of benefit in both inflammatory and non-inflammatory acne. Current surveys suggest that implementation of the pregnancy prevention programme for isotretinoin may not be stringent, and a high level of monitoring and audit is recommended. Ablative and non-ablative laser resurfacing for the treatment of acne scars may be beneficial, but further studies with a longer follow-up period are required.

    2014-01-01

    Objective: Acne vulgaris is a chronic inflammatory disease, and hormonal influences, follicular plugging and follicular hyperkeratinization, increased sebum secretion, Propionibacterium acnes colonization, and inflammation are involved in its pathogenesis. Recently, a significant body of evidence has accumulated that describes the comedolytic properties of vitamin D and its roles as a modulator of the immune system, a regulator of the proliferation and differentiation of sebocytes and keratinocytes, and as an antioxidant. In this study, we aimed to compare serum vitamin D levels in a group of patients with nodulocystic acne with vitamin D levels in a group of control subjects to determine whether there was any relationship between the vitamin D and acne. Methods: Levels of 25-hydroxyvitamin D (25[OH]D) were measured in 43 patients with newly diagnosed nodulocystic acne and in 46 healthy control subjects, and participants were grouped according to their 25[OH]D levels as follows: normal/sufficient (>20 ng/mL) or insufficient/deficient (<20 ng/mL). Serum concentrations of calcium (Ca), phosphorus (P), alkaline phosphatase (ALP), and parathyroid hormone (PTH) were measured. Results: Forty-three patients and 46 control individuals, with mean ages of 23.13 (± 5.78) years and 25.23 (± 4.73) years, respectively, were included in this study. There were no significant differences between the groups in relation to their body mass indices and Ca, P, ALP, and PTH levels. However, the patients with nodulocystic acne had significantly lower 25[OH]D levels than the subjects in the control group (P< 0.05). Conclusion: The patients with nodulocystic acne had relatively low serum vitamin D levels compared with the subjects in the control group. The findings from this study suggest that there is a connection between low vitamin D levels and acne. Larger epidemiologic studies are needed to confirm the status of vitamin D levels in patients with acne. PMID:26413187

    Objective: To assess the efficacy and safety of a topical gel containing clindamycin 1.2% and tretinoin 0.025% for the treatment of acne and acne-induced postinflammatory hyperpigmentation (PIH) in darker skinned patients. Design: Randomized, double-blind, placebo-controlled study. Setting: Two United States clinical sites. Participants: Thirty-three patients 12 years of age or older with skin types IV to VI, mild-to-moderate facial acne, and PIH were enrolled. Measurements: Patients applied clindamycin phosphate/tretinoin gel or a nonmedicated vehicle each evening and a sun protection factor 30 sunscreen daily. Changes in skin erythema and hyperpigmentation were measured using a chromameter and photographic images. Efficacy was assessed using the Evaluators Global Acne Severity Scale, lesion counts, Post-inflammatory Hyperpigmentation Severity Scales and Patient’s Global Assessment Scale. Safety and tolerability were assessed by adverse event reports and a Safety Assessment Scale. Results: The mean (SD) baseline inflammatory lesion count was 11.9 (11.1) in clindamycin/tretinoin-treated patients, decreasing by 5.5 (6.56) after 12 weeks while the mean baseline inflammatory lesion count was 13.6 (11.15) in placebo-treated patients, decreasing by 4.1 (11.36) (p=0.05 for change from baseline, clindamycin/tretinoin vs. placebo). Clindamycin/tretinoin-treated patients generally demonstrated superior efficacy versus placebo treatment. The clindamycin/tretinoin topical gel was well tolerated, causing little or no irritation, although one patient withdrew due to periorbital edema of moderate severity possibly related to clindamycin/tretinoin gel. Conclusion: Although limited by small sample size, the results of this pilot study suggest clindamycin phosphate 1.2% and tretinoin 0.025% topical gel is a safe and effective option for treating mild-to-moderate acne in patients with skin of color.

    Approximately 95% of the population suffers at some point in their lifetime from acne vulgaris. Acne is a multifactorial disease of the pilosebaceous unit. This inflammatory skin disorder is most common in adolescents but also affects neonates, prepubescent children, and adults. Topical conventional systems are associated with various side effects. Novel drug delivery systems have been used to reduce the side effect of drugs commonly used in the topical treatment of acne. Topical treatment of acne with active pharmaceutical ingredients (API) makes direct contact with the target site before entering the systemic circulation which reduces the systemic side effect of the parenteral or oral administration of drug. The objective of the present review is to discuss the conventional delivery systems available for acne, their drawbacks, and limitations. The advantages, disadvantages, and outcome of using various carrier-based delivery systems like liposomes, niosomes, solid lipid nanoparticles, and so forth, are explained. This paper emphasizes approaches to overcome the drawbacks and limitations associated with the conventional system and the advances and application that are poised to further enhance the efficacy of topical acne formulations, offering the possibility of simplified dosing regimen that may improve treatment outcomes using novel delivery system.

    The objectives of the current investigation are (1) to prepare and characterize (particle size, surface charge (potential zeta), surface morphology by transmission electron microscopy, drug content, and drug release) the azithromycin (AZM, 100 mg)-loaded oil-in-water (o/w) macroemulsion, (2) to assess the toxicity of macroemulsion with or without AZM using RBC lysis test in comparison with AZM in phosphate buffer solution of pH 7.4, (3) to compare the in vitro antimicrobial activity (in Escherichia coli using zone inhibition assay) of AZM-loaded macroemulsion with its aqueous solution, and (4) to assess the in vitro anti-inflammatory effect (using egg albumin denaturation bioassay) of the AZM-loaded macroemulsion in comparison with diclofenac sodium in phosphate buffer solution of pH 7.4. The AZM-loaded macroemulsion possessed the dispersed oil droplets with a mean diameter value of 52.40 ± 1.55 μm. A reversal in the zeta potential value from negative (-2.16 ± 0.75 mV) to positive (+6.52 ± 0.96 mV) was noticed when AZM was added into the macroemulsion. At a 1:5 dilution ratio, 2.06 ± 0.03 mg of drug was released from macroemulsion followed by 1.01 ± 0.01 and 0.25 ± 0.08 mg, respectively, for 1:10 and 1:40 dilution ratios. Antimicrobial activity maintenance and significant reduction of RBC lysis property were noticed for AZM after loaded in the macroemulsion. However, an increment in the absorbance values for emulsion-treated samples in comparison to the control samples was noticed in the anti-inflammatory test. This speculates the potential of the AZM-loaded emulsion to manage inflammatory conditions produced at Acne vulgaris.

    Acne is a chronic inflammatory disease of the pilosebaceous unit that affects almost all teenagers. Different treatments offer different modes of action, but aim to target acne pathology. Topical therapies, such as benzoyl peroxide, retinoids, antibiotics with alcohol-based preparations, and salicylic acid, can cause skin irritation resulting in a lack of patient adherence. Some physicians recommend patients use moisturizers as adjunctive treatment of acne, especially when either topical benzoyl peroxide or a retinoid is prescribed. Furthermore, some evidence shows that moisturizers can contribute independently to improve signs and symptoms of acne. Moisturizers contain three main properties, which are occlusive, humectant, and emollient effects. Currently, many moisturizers claim to be suitable for acne treatment. This article aims to provide a review of the active ingredients and properties of those moisturizers. Fifty-two moisturizers for acne were included for analysis. Most of the products (92%) have anti-inflammatory properties apart from occlusive, humectant, and emollient effects. Anti-acne medications, including salicylic acid, benzoyl peroxide, and retinol, were found respectively in 35, 10, and 8 percent of the moisturizer products containing anti-inflammatory properties. More than half of the products contain dimethicone and/or glycerin for its moisturizer property. Aloe vera and witch hazel are botanical anti-inflammatories that were commonly found in this study. Scientific data regarding some ingredients are discussed to provide a guide for physicians in selecting moisturizers for acne patients. PMID:24847408

    Making accurate diagnoses when certain lesions are in a relatively young stage can prove challenging, as their "textbook descriptions" are often not fully apparent, and may in fact be markedly different. The authors present three interesting cases of early lesions that were clinically difficult to differentiate from one another: a cystic variation of a keratoacanthoma squamous cell carcinoma, a basal cell carcinoma, and an excoriated facial acne vulgaris. The subtle clinical nuances found in each of these cases demonstrated the importance of a careful clinical evaluation; however, this was not sufficient for adequate assessment of whether or not to biopsy. With early lesions such as these, the use of the noninvasive imaging modalities of dermoscopy and optical coherence tomography becomes critical in order to avoid unnecessary biopsy. The discussion of the clinically and dermoscopically challenging features is both instructive and enlightening. Oftentimes, "textbook descriptions" of lesions focus on the description of an already mature stage of growth, despite the fact that we continue to strive toward earlier detection of potential malignancies. With this in mind, the features found with optical coherence tomography proved essential to the elucidation of these difficult lesions. These three interesting cases illustrated the challenges encountered when dealing with early lesions specifically. The authors bring to light features in each of these cases that are often not thought of as being the "typical" presentation in each lesion category and demonstrate the clinical utility of noninvasive devices in difficult-to-diagnose cases such as these.

    There is compelling evidence that oral contraceptives (OCs) are effective in the management of mild-moderate acne vulgaris, as well as cumulative evidence that elevated levels of androgens in acne patients, relative to appropriate controls, are an underlying pathophysiological factor in acne. All low dose OCs reduce serum free testosterone (T) to a similar extent, which is contrary to the traditional concept that a patient who has acne should not use an OC containing a progestin with androgenic properties. The efficacy of various OCs to improve acne has been reported in transverse, cohort and comparative studies, and more recently in multicenter, randomized, placebo-controlled trials. Recently, an ultra-low dose OC (Alesse, Wyeth) was shown to effectively reduce non-inflammatory and inflammatory lesions in mild-to-moderate acne, while having a profile of side-effects similar to that of a placebo. Besides its contraceptive efficacy, an ultra-low dose OC represents an attractive alternative as a single or associated medication in the management of acne.

    Acne, one of the most common skin diseases, affects approximately 85% of the adolescent population, and occurs most prominently at skin sites with a high density of sebaceous glands such as the face, back, and chest. Although often considered a disease of teenagers, acne is occurring at an increasingly early age. Rosacea is a chronic facial inflammatory dermatosis characterized by flushing (or transient facial erythema), persistent central facial erythema, inflammatory papules/pustules, and telangiectasia. Both acne and rosacea have a multifactorial pathology that is incompletely understood. Increased sebum production, keratinocyte hyper-proliferation, inflammation, and altered bacterial colonization with Propionibacterium acnes are considered to be the underlying disease mechanisms in acne, while the multifactorial pathology of rosacea is thought to involve both vasoactive and neurocutaneous mechanisms. Several advances have taken place in the past decade in the research field of acne and rosacea, encompassing pathogenesis and epidemiology, as well as the development of new therapeutic interventions. In this article, we provide an overview of current perspectives on the pathogenesis and treatment of acne and rosacea, including a summary of findings from recent landmark pathophysiology studies considered to have important implications for future clinical practice. The advancement of our knowledge of the different pathways and regulatory mechanisms underlying acne and rosacea is thought to lead to further advances in the therapeutic pipeline for both conditions, ultimately providing a greater array of treatments to address gaps in current management practices.

  5. Lymphocyte transformation in subjects with nodulo cystic acne.

    PubMed

    1977-08-01

    Patients with severe nodulo-cystic acne are known to have elevated serum antibody levels and increased immediate hypersensitivity reactions to Propionibacterium acnes. This organism is the predominant bacterium in normal pilosebaceous follicles of human skin, and can be consistently isolated from pustular lesions in acne. Previously it had been observed that delayed cutaneous hypersensitivity reactions to P. acnes were negative in patients with acne. The present study investigated the proliferative response of lymphocytes from patients with nodulo-cystic acne to phytohaemagglutinin (PHA) and P. acnes antigen stimulation. The response to PHA stimulation was within normal limits. The response to P. acnes antigen showed a significant increase over control values obtained by testing lymphocytes from acne-free subjects. Thus cell mediated immunity to P. acnes may be present in subjects with severe inflammatory acne. These findings raise the possibility that reactions to P. acnes may contribute to intensifying the inflammatory response in acne lesions.

    Background. Post-adolescent acne is an inflammatory disorder, whose cause is unknown. Contrasting data are available on correlation between acne and smoking habit. Objectives. To verify the frequency of clinically non-inflammatory (atypical) post-adolescent acne (APAA) among women, a possible correlation with cigarette smoking, possible differences in sebum composition in a group of female smokers with acne compared to healthy smokers and non-smokers. Method and results. 1046 randomly selected women (25–50-years-old) participated at the study. In 60 selected female subjects we analyzed sebum composition for α-tocopherol, squalene and squalene monohydroperoxide. We found a high prevalence of APAA among women (74.6%), a strong correlation with smoking habit (p < 0.0001), as well as an increase in the grade of sebum peroxidation (p < 0.05) with a reduction in vitamin E (p = 0.02), in the subjects with acne compared to the controls. Conclusions. Clinical evidence and experimental data showed a straight correlation between smoking habit and post-pubertal acne in which the clinically non-inflammatory type—APAA—is the most frequent. In the more severe cases we could consider APAA as a new entity (smoker’s acne). PMID:20436880

Erythema, papules, pustules and telangiectases, the main clinical manifestations of the disease are located on the face. Currently opinions dealing with pathogenesis and clinical forms of rosacea are presented. As the clinical picture might be confusing, similar to other illnesses, differential diagnosis with other dermatoses like acne vulgaris, erysipelas, seborrhoeic and contact eczema as well as systemic diseases like lupus erythematosus, dermatomyositis, scleroderma, sarcoidosis and leukemia were discussed.

    Conventional acne treatment presents several challenges such as intolerable side effects and antibiotic resistance. Dermocosmetic products may be used to reduce these unwanted effects. Dermocosmetics include skin cleansers, topical sebum-controllers, skin antimicrobial/anti-inflammatory agents, moisturizers, sunscreens, and camouflage products. Appropriate use of these products may help augment the benefit of acne treatment, minimize side effects, and reduce the need for topical antibiotics. In Asia, there is currently limited scientific data on the application and recommendations for dermocosmetic use in acne vulgaris (AV). This article reviews the evidence on dermocosmetics for AV and provides practice recommendations as discussed during the 4th Asia-Pacific Acne Leaders' Summit held in Bangkok, Thailand, on 7 and 8 February 2015. Through a premeeting survey, a series of plenary lectures, a stepwise program of discussion sessions, and Medline article review, the Expert Panel set forth relevant recommendations on the role of dermocosmetics as adjunct for treating AV in Asian patients.

  10. Linking diet to acne metabolomics, inflammation, and comedogenesis: an update

    PubMed Central

    Melnik, Bodo C

    2015-01-01

    Acne vulgaris, an epidemic inflammatory skin disease of adolescence, is closely related to Western diet. Three major food classes that promote acne are: 1) hyperglycemic carbohydrates, 2) milk and dairy products, 3) saturated fats including trans-fats and deficient ω-3 polyunsaturated fatty acids (PUFAs). Diet-induced insulin/insulin-like growth factor (IGF-1)-signaling is superimposed on elevated IGF-1 levels during puberty, thereby unmasking the impact of aberrant nutrigenomics on sebaceous gland homeostasis. Western diet provides abundant branched-chain amino acids (BCAAs), glutamine, and palmitic acid. Insulin and IGF-1 suppress the activity of the metabolic transcription factor forkhead box O1 (FoxO1). Insulin, IGF-1, BCAAs, glutamine, and palmitate activate the nutrient-sensitive kinase mechanistic target of rapamycin complex 1 (mTORC1), the key regulator of anabolism and lipogenesis. FoxO1 is a negative coregulator of androgen receptor, peroxisome proliferator-activated receptor-γ (PPARγ), liver X receptor-α, and sterol response element binding protein-1c (SREBP-1c), crucial transcription factors of sebaceous lipogenesis. mTORC1 stimulates the expression of PPARγ and SREBP-1c, promoting sebum production. SREBP-1c upregulates stearoyl-CoA- and Δ6-desaturase, enhancing the proportion of monounsaturated fatty acids in sebum triglycerides. Diet-mediated aberrations in sebum quantity (hyperseborrhea) and composition (dysseborrhea) promote Propionibacterium acnes overgrowth and biofilm formation with overexpression of the virulence factor triglyceride lipase increasing follicular levels of free palmitate and oleate. Free palmitate functions as a “danger signal,” stimulating toll-like receptor-2-mediated inflammasome activation with interleukin-1β release, Th17 differentiation, and interleukin-17-mediated keratinocyte proliferation. Oleate stimulates P. acnes adhesion, keratinocyte proliferation, and comedogenesis via interleukin-1α release. Thus, diet

    A 12-week double-blind randomized study was performed to compare benzoyl peroxide 5% (BP) gel and chloroxylenol 0.5% plus salicylic acid 2% (PCMX + SA) cream (Nisal cream) for efficacy and adverse reactions. Thirty-seven volunteers participated in the study, 19 in the BP group and 18 in the PCMX + SA group. The patients applied the medication twice daily to the entire face. Clinical evaluation and lesion counts were obtained at 0, 3, 6, 9 and 12 weeks. At week 12 both groups showed a marked improvement in both inflammatory and noninflammatory lesions (60% and 54% for the BP group and 62% and 56% for and 56% for the PCMX + SA group, respectively). Although PCMX + SA showed a slightly stronger keratolytic effect throughout the study period, there was no statistically significant difference in the reduction of the papulopustules or comedones between the two groups. Adverse effects such as erythema and photosensitivity were significantly fewer in the PCMX + SA group at week 12 (p = 0.0002 and p = 0.05, respectively). These results suggest that PCMX + SA cream is as effective as BP gel in the treatment of papulopustular and comedonal acne and that it is better tolerated.

  12. A review of the safety and efficacy of benzoyl peroxide (5.3%) emollient foam in the management of truncal acne vulgaris.

    This article reviews findings of studies regarding the treatment of truncal acne with benzoyl peroxide formulations and, in particular, studies utilizing a 5.3% benzoyl peroxide foam. Its formulation of micronized benzoyl peroxide particles in an emollient foam vehicle offers significant clinical and bioavailability advantages that enhance follicular penetration and skin moisturization. A key consideration for topical management of truncal acne is whether the treatment application method allows adequate skin contact time to reduce Propionibacterium acnes colony counts. The foam formulation has demonstrated significant reduction in Propionibacterium acnes on the back when used either as a leave-on or as short-contact therapy for five minutes. Short-contact therapy with a benzoyl peroxide foam is a novel approach to minimize the risk of benzoyl peroxide bleaching of clothing in truncal acne patients.

  13. Female acne - a different subtype of teenager acne?

    Above all, acne is considered an adolescent affection. However, in literature as in daily life, female acne is becoming more and more common. According to the articles that cover this subject, the prevalence is estimated from 40% to 50%. The objective of our work was to make an overview of new data about female acne at the clinical and epidemiological level to be precise if female acne has to be considered as a subtype of acne different from teenager acne. This review shows that the most frequently recognized age when speaking about female acne is 25 years old. Most commonly it is a light to moderate acne that mainly affects the face. Two clinical forms can be identified: an inflammatory form, the most frequent, made up of papulo-pustules and nodules on the lower part of the face and a retentional form made up of blackheads and micro cysts with hyperseborrhoea. Concerning its evolution, it is characterized by three subtypes of which two are predominant: the most frequent form called 'continue acne' from adolescence to adult age and the less frequent form called 'late onset acne' that starts after 25 years of age. On a physiopathological level two main hypotheses can be proposed. Specific global assessment and therapeutic algorithm would be necessary for female acne, which in addition, in future would have to be considered separately from teenagers for the evaluation of a new drug.

    Propionibacterium acnes (P. acnes), one of the anaerobic bacterium, causes inflammatory acne. To find a novel medication for treating the inflammation caused by P. acnes, we investigated the anti-bacterial and anti-inflammatory activities of several herbal extracts against P. acnes. The aqueous extracts from five dried herbs, Phellodendron amurense Rupr., Paeonia lactiflora Pallas., Houttuynia cordata Thunb., Agrimonia pilosa Ledeb. and Glycyrrhiza uralensis Fisch., were prepared and mixed. In this experiment, 1 mg/ml of the herbal extract mixture caused a decrease in the growth of P. acnes and reduced the production of pro-inflammatory cytokines, TNF-α, IL-8, IL-1β and IL-6, in human monocytic THP-1 cells treated with heat-killed P. acnes. Therefore, this herbal extract mixture may possess both anti-bacterial and anti-inflammatory activities against P. acnes and can be a novel therapeutic agent for treating inflammatory acne.

  16. Lipid Mediators in Acne

    Ottaviani, Monica; Camera, Emanuela; Picardo, Mauro

    2010-01-01

    Multiple factors are involved in acne pathogenesis, and sebum secretion is one of the main ones. The role sebum plays in acne development has not been completely elucidated yet; however, increasing amounts of data seem to confirm the presence of alterations in sebum from acne patients. Altered ratio between saturated and unsaturated fatty acids has been indicated as an important feature to be considered in addition to the altered amount of specific fatty acids such as linoleic acid. Furthermore, particular attention has been focused on squalene peroxide that seems to be able to induce an inflammatory response beyond cytotoxicity and comedones formation. Moreover, recent data suggest that lipid mediators are able to interfere with sebocytes differentiation and sebogenesis through the activation of pathways related to peroxisome proliferators-activated receptors. Understanding the factors and mechanisms that regulate sebum production is needed in order to identify novel therapeutic strategies for acne treatment. PMID:20871834

    Introduction The pathogenesis of acne is complex, multifactorial and not well understood. The genetic background of this dermatosis is well documented. Aim To assess the frequency of –34 T > C single nucleotide polymorphism in the promoter of the CYP17 gene as well as m1 (+6,235 T > C) and m2 (+4,889 A > G) mutation in the coding region CYP1A1 gene acne patients from the Northern Polish population. Material and methods The study included 115 acne patients and 94 healthy controls (aged over 20) without acne in anamnesis. The CYP1A1 polymorphism was analyzed by polymerase chain reaction (PCR). The restriction fragment length polymorphism (RFLP) was used to analyze m1 mutation and allele-specific PCR in the case of m2 mutation. The CYP17 polymorphism was analyzed by RFLP. The results were evaluated by the Pearson's χ2 test. Results There were no statistically significant associations between allele and genotype frequencies between the acne and the control group. Conclusions We did not confirm the role of the CYP1A1 and CYP17 gene as predictor factors for acne development in the Polish population. PMID:26759538

  18. New developments in acne treatment: role of combination adapalene–benzoylperoxide

    2016-01-01

    The fixed-dose combination adapalene 0.1%/benzoylperoxide 2.5% (A/BPO) was introduced as an acne vulgaris therapeutic in 2007. It combines anti-inflammatory, keratolytic, comedolytic, and antibacterial properties. Thus, it addresses several pathophysiological factors involved in the pathophysiology of acne. This review highlights the rationale for the use of this fixed-dose combination product, its therapeutic efficacy including effects on adherence and quality of life, its use for different forms of acne, and the side-effect profile. In summary, the fixed-dose combination of A/BPO gel can be regarded as a highly effective and safe formulation. It is not associated with antibiotic resistance. It reduces factors that cause nonadherence and has positive effects on the quality of life of affected patients. The tolerance is good. The initial mild irritation potential can be addressed by adequate counseling. A/BPO can be used for all forms of inflammatory acne, including severe forms, as part of a combination with systemic antibiotics. Finally, it can also be used for the long-term treatment of chronic acne. Thus, it is a very valuable therapeutic option in daily practice, which is reflected by its strong recommendation in the “European S3-guidelines”. PMID:27757036

    Background. Although isotretinoin orally is commonly used for moderate to severe or scarring acne, it is not a cure. Unfortunately recurrence is unpredictable and varies within the acne population. Objectives. Using a proof of concept study, determine the recurrence of acne after isotretinoin use in male patients. Methods. Twenty males aged 18-45 years old were enrolled. Subjects successfully completed a treatment of acne vulgaris with oral isotretinoin (120-150 mg/kg/course). Subjects were randomized 1 to 1. The study duration was 24 weeks. The primary endpoint measured was the absolute change in lesion counts from baseline to weeks 16 and 24. Local tolerability assessments were measured. Results. There were favorable changes in all outcomes measured. Overall, there was a 38.7% lower lesion count with tretinoin 0.04% microsphere gel use versus vehicle. The active product was well tolerated with great patient satisfaction. There were no significant safety issues. The limitations included the low number of patients enrolled, average age, and percentage of patients lost to follow-up. Conclusion. In summary, the results favored tretinoin 0.04% microsphere gel in the prevention of recurrent acne after isotretinoin use in male patients over 18 years old over a six-month period.

    Certain bacteria are able to synthesize metal-free fluorescent porphyrins and can therefore be detected by sensitive autofluorescence measurements in the red spectral region. The porphyrin-producing bacterium Propionibacterium acnes, which is involved in the pathogenesis of acne vulgaris, was localized in human skin. Spectrally resolved fluorescence images of bacteria distribution in the face were obtained by a slow-scan CCD camera combined with a tunable liquid crystal filter. The structured autofluorescence of dental caries and dental plaque in the red is caused by oral bacteria, like Bacteroides or Actinomyces odontolyticus. `Caries images' were created by time-gated imaging in the ns-region after ultrashort laser excitation. Time-gated measurements allow the suppression of backscattered light and non-porphyrin autofluorescence. Biopsies of oral squamous cell carcinoma exhibited red autofluorescence in necrotic regions and high concentrations of the porphyrin-producing bacterium Pseudomonas aerigunosa. These studies suggest that the temporal and spectral characteristics of bacterial autofluorescence can be used in the diagnosis and treatment of a variety of diseases.

    2010-01-01

    Acne vulgaris is one of the most common conditions for which all patients, including those with skin of color (Fitzpatrick skin types IV–VI), seek dermatological care. The multifactorial pathogenesis of acne appears to be the same in ethnic patients as in Caucasians. However, there is controversy over whether certain skin biology characteristics, such as sebum production, differ in ethnic patients. Clinically, acne lesions can appear the same as those seen in Caucasians; however, histologically, all types of acne lesions in African Americans can be associated with intense inflammation including comedones, which can also have some degree of inflammation. It is the sequelae of the disease that are the distinguishing characteristics of acne in skin of color, namely postinflammatory hyperpigmentation and keloidal or hypertrophic scarring. Although the medical and surgical treatment options are the same, it is these features that should be kept in mind when designing a treatment regimen for acne in skin of color. PMID:20725545

    Propionibacterium acnes is associated with purulent skin infections, and it poses a global problem for both patients and doctors. Acne vulgaris (acne) remains a problem due to its chronic character and difficulty of treatment, as well as its large impact on patients' quality of life. Due to the chronic course of the disease, treatment is long lasting, and often ineffective. Currently there are data regarding isolation of P. acnes phages, and there have been numerous studies on phage killing of P. acnes, but no data are available on phage application specifically in acne treatment. In this review, we have summarized the current knowledge on the phages active against P. acnes described so far and their potential application in the treatment of acne associated with P. acnes. The treatment of acne with phages may be important in order to reduce the overuse of antibiotics, which are currently the main acne treatment. However, more detailed studies are first needed to understand phage functioning in the skin microbiome and the possibility to use phages to combat P. acnes. PMID:28228751

  4. Objective assessment of acne.

    A precise and reliable assessment of acne severity is unarguably the most essential clinical method when it comes to monitoring and choosing optimal treatment in the daily practice. Since the early 1960s, different severity assessment systems have been described in the literature. The two commonly used concepts are global gradings and lesion counting. Both systems have been controversially discussed as to which is more reliable and providing an objective outcome measurement tool; however, both have some subjectivity involved. More objective methods for assessing the severity of acne vulgaris include photography, fluorescence photography, polarized light photography, video microscopy, and multispectral imaging. Such techniques have limitations such as high cost, complex and sophisticated apparatus, and a sometimes time-consuming imaging process. There are newly developed technologies that could avoid the problems of inter- and intrarater subjectivity.

    The treatment of acne and acne scarring with lasers and light-based and energy-based technologies has become an integral component of our therapeutic arsenal. Lasers including infrared wavelengths and pulsed dye lasers; light devices including blue light, red light, and broadband light; and photodynamic therapy with aminolevulinic acid and methylaminolevulinic acid have been shown to be effective in the treatment of acne vulgaris. The optimal outcomes are achieved with photodynamic therapy combined with medical therapy. Acne scarring has been best treated with lasers, including nonablative infrared lasers, fractional nonablative and ablative laser resurfacing, and most recently needle-based radiofrequency devices.

    The antibacterial and anti-inflammatory potential of natural, plant-derived compounds has been reported in many studies. Emerging evidence indicates that plant-derived essential oils and/or their major compounds may represent a plausible alternative treatment for acne, a prevalent skin disorder in both adolescent and adult populations. Therefore, the purpose of this study was to develop and subsequently analyze the antimicrobial activity of a new multi-agent, synergic formulation based on plant-derived antimicrobial compounds (i.e., eugenol, β-pinene, eucalyptol, and limonene) and anti-inflammatory agents for potential use in the topical treatment of acne and other skin infections. The optimal antimicrobial combinations selected in this study were eugenol/β-pinene/salicylic acid and eugenol/β-pinene/2-phenoxyethanol/potassium sorbate. The possible mechanisms of action revealed by flow cytometry were cellular permeabilization and inhibition of efflux pumps activity induced by concentrations corresponding to sub-minimal inhibitory (sub-MIC) values. The most active antimicrobial combination represented by salycilic acid/eugenol/β-pinene/2-phenoxyethanol/potassium sorbate was included in a cream base, which demonstrated thermodynamic stability and optimum microbiological characteristics.

    Background: Acne is a self limiting condition that often results in scarring and disfigurement disproportionate to its clinical severity. Isotretinoin is considered the gold standard in the medical management of severe form of acne vulgaris. Salicyclic acid (SA) peels, a β- hydroxy acid peel has got sebosuppressive effect and helps in faster resolution of acne with minimal scarring. It also decreases the post inflammatory hyperpigmentation. Combining both the modalities is usually not advocated because of expected excessive dryness and irritation Aims: To compare the efficacy of oral isotretinoin and oral isotretinoin with 20% SA peels in patients with moderate to severe acne. Materials and Methods: 60 consecutive patients with moderate to severe facial acne attending the skin department were randomized in to 2 groups. 1st group received 20mg oral isotretinoin once daily for 16 weeks and 2nd group received 20mg oral isotretinoin once daily along with 20% SA peels every two weeks for 16 weeks. Baseline grading of acne was done with Michelsons Acne severity index (MASI).Right and left sides of the face were scored separately and total score was taken. Severity score was assessed monthly .Clinical photographs were obtained for evaluation every month. Patients were asked to follow up once every 2 weeks or earlier in case of any adverse events. Results: Patients in both the groups revealed a reduction in the number of lesions. The 1st group showed a reduction of approximately 73.4% after receiving 20mg oral isotretinoin for 16 weeks. The 2nd group showed a reduction of approximately 92.5 % after receiving 20mg oral isotretinoin along with 20% SA peel once every 2 weeks for 16 weeks. Conclusion: Both oral isotretinoin and combination of oral isotretinoin with 20% SA peels once every 2 weeks are effective in treating moderate to severe acne but the combination showed significantly better clearance of acne than monotherapy with isotretinoin.

    Scutellariae radix, the root of Scutellaria baicalensis, has long been applied in traditional formulations and modern herbal medications. Propionibacterium acnes (P. acnes) in follicles can trigger inflammation and lead to the symptom of inflammatory acnes vulgaris. This study was aimed at evaluating the effect of Scutellariae radix extract and purified components isolated from it on inflammation induced by P. acnes in vitro and in vivo. The results showed the ethyl acetate (EA) soluble fraction from the partition of crude ethanolic extract from Scutellariae radix inhibited P. acnes-induced interleukin IL-8 and IL-1β production in human monocytic THP-1 cells. Seven flavones were isolated from the EA fraction by repeated chromatographies, and identified as 5,7-dihydroxy-6-methoxyflavone (FL1, oroxylin), 5,7-dihydroxy-8-methoxyflavone (FL2, wogonin), 5-hydroxy-7,8-dimethoxyflavone (FL3, 7-O-methylwogonin), 5,6'-dihydroxy-6,7,8,2'-tetramethoxy flavone (FL4, skullcapflavone II), 5,7,4'-trihydroxy-8-methoxyflavone (FL5), 5,2',6'-trihydroxy-7,8-dimethoxyflavone (FL6, viscidulin II), and 5,7,2',5'-tetrahydroxy-8,6'-dimethoxyflavone (FL7, ganhuangenin). They all significantly suppressed P. acnes-induced IL-8 and IL-1β production in THP-1 cells, and FL2 exerted the strongest effect with half maximal inhibition (IC50) values of 8.7 and 4.9 μM, respectively. Concomitant intradermal injection of each of the seven flavones (20 μg) with P. acnes effectively attenuated P. acnes-induced ear swelling, and decreased the production of IL-6 and tumor necrosis factor-α in ear homogenates. Our results suggested that all the seven flavones can be potential therapeutic agents against P. acnes-induced skin inflammation.

    Acne rosacea is a chronic skin disorder that requires long-term therapy. Oral azithromycin has been used successfully to treat acne vulgaris. an observation that suggested an infectious agent may play an active role in the etiology of this disorder. Ten adults (not previously reported) with acne rosacea were selected to be treated with oral azithromycin. Nine of the 10 subjects received 250 mg 3 times weekly for periods ranging from 5 to 19 weeks, at which time follow-up examinations were performed on 8 of the 9 treated subjects: 1 subject was lost to follow-up. Prior to therapy. C pneumoniae antigen was detected in malar biopsy specimens in 4 of 10 subjects by immunoperoxidase technique (using monoclonal antibody to C pneumoniae). Serum antibodies against C pneumoniae were detected in 8 of 10 intent-to-treat subjects. Using polymerase chain reaction, C pneumoniae was not detected in peripheral blood mononuclear cells. The inflammatory response in tissues was characterized by a widespread infiltration of polymorphonuclear neutrophil cells, lymphocytes, and plasma cells, which support the clinical diagnosis of acne rosacea. Nine of 10 subjects treated with azithromycin showed moderate to marked improvement of their acne rosacea. No adverse reactions to azithromycin occurred. and the drug appeared to be safe and effective. These preliminary data suggest the need for further investigation with clinical trials to study long-term tolerability and efficacy and also strongly implicate C pneumoniae in the pathogenesis of acne rosacea.

    Benzoyl peroxide (BPO) as an anti-acne medication is not yet approved in Japan. This study evaluated the efficacy and safety of a once-daily topical application of BPO 3% gel versus an inert vehicle gel in Japanese acne patients. Three hundred and sixty patients were randomized to receive BPO 3% or vehicle for 12 weeks. The primary efficacy end-point was absolute change in number of total lesions (TL) from baseline to week 12 to demonstrate the superiority of BPO 3% versus vehicle. Secondary efficacy end-points were absolute and percent change in TL, inflammatory lesions (IL), non-inflammatory lesions (non-IL) and Investigator's Static Global Assessment (ISGA). Change in TL counts from baseline to week 12 for BPO 3% was superior to vehicle (difference, -21.0; P < 0.001). Absolute and percent reductions in TL, IL and non-IL counts were greater for BPO 3% at all study visits. The proportion of patients with improvement in ISGA scores was significantly higher with BPO 3% than with vehicle from week 2. All adverse events were mild or moderate. Adverse drug-related reactions were higher for BPO 3% (30%) than with vehicle (5%). Local tolerability scores of grade 1 or more (slight to moderate) were more frequent with BPO 3% than vehicle with the most significant differences observed in dryness (56% vs 27% at week 1-4), peeling (19% vs 9% at week 1-2) and burning/stinging (58% vs 15% at week 1-12). These results indicate that BPO 3% is effective while maintaining a favorable safety and tolerability profile in Japanese acne patients.

    Acne vulgaris is usually considered as a skin disorder that primarily affects adolescents reaching a peak at the age of 14–17 years in females and 16–19 years in males. However, recent epidemiologic studies have shown that a significant number of female patients aged >25 years experience acne. As it is regarded as a disease of teenagers, adults are more apprehensive and experience social anxiety. Hence, adult onset acne has become a matter of concern. PMID:27512185

    Background: Acne vulgaris is a chronic inflammatory disease of the pilosebaceous follicles and one of the most common skin diseases. The peeling method has been recently found to be effective for acne treatment. This study aimed to compare the efficacy of pyruvic acid 50% and salicylic acid 30% peeling in the treatment of mild to moderate acne. Materials and Methods: In a prospective single-blinded clinical trial, 86 patients with acne were randomly assigned into two groups. In both groups, the routine treatment of acne (topical solution of erythromycin 4%, triclorocarban soap, and sunscreen) were used twice a day for 8 weeks. In addition, salicylic acid 30% for the control group and pyruvic acid 50% for the case group were used. In both groups, acne severity index (ASI) was calculated before and at week 2, 4, 6, and 8 of the treatment. Patient satisfaction was assessed at the end of the treatment. Side effects were recorded using a checklist. Results: In both groups, the reduction in the number of comedones, papules, and ASI were statistically significant (P < 0.001) in the course of treatment. However, it was not significant regarding the number of pustules (P = 0.09). None of the number of comedone, papules, pustules, and ASI was statistically different between study groups. Both treatment groups had similar side effects except for scaling in the fifth session, which was significantly lower in salicylic acid – treated patients (P = 0.015). Conclusion: Both pyruvic acid 50% and salicylic acid 30% are effective in the improvement of mild to moderate acne with no significant difference in efficacy and side effects. PMID:27904577

    Acne vulgaris is a common reason why adult women present to dermatologists and can be a clinical challenge to treat. It may also be an important sign of an underlying endocrine disease such as Polycystic Ovary Syndrome (PCOS). Although standard acne therapies can be successfully used to treat acne in adult female patients, hormonal treatment is a safe and effective therapeutic option that may provide an opportunity to better target acne in this population, even when other systemic therapies have failed. In this article, a practical approach to the adult female patient with acne will be reviewed to enhance the dermatologist's ability to use hormonal acne therapies and to better identify and evaluate patients with acne in the setting of a possible endocrine disorder.

    2009-01-01

    Tissue inflammation is a major component of the acne process. Leukotriene B4 (LTB4) is considered to be a major player in the development of tissue inflammation. Synthesis of LTB4 is controlled by the enzyme 5-lipoxygenase. Since Zileuton blocks the activity of 5-lipoxygenase, experimental and clinical studies have been conducted to test mode of function, as well as efficacy and safety of this compound in the treatment of acne vulgaris. Human SZ95 sebocytes and inflammatory cells in vitro express the enzymes of the leukotriene pathway at mRNA and protein levels and enzymes involved in the biosynthesis of LTB4 are activated in sebaceous glands of acne lesions. Pre-treatment of SZ95 sebocytes with Zileuton partially prevented short-term arachidonic acid-induced effects, such as induction of LTB4, increase of neutral lipid content and stimulation of interlekin-6 release. Long-term treatment with Zileuton directly reduced the content of neutral lipids and interleukin-6 release from SZ95 seb ocytes. PPAR mRNA levels were not regulated by Zileuton. In a first pilot clinical study with 10 patients with papulopustular acne Zileuton 4 × 600 mg/d p.o. for 3 months decreased the acne severity index in a time-dependent manner being 41% of the initial score at week 12 (p < 0.05). This was mostly due to a decrease of the number of inflammatory lesions of 29% (p < 0.01). In addition, total sebum lipids significantly decreased (35%, p < 0.05) and the pro-inflammatory free fatty acids (22%) and lipoperoxides (26%) were markedly diminished in patients’ sebum under treatment. The magnitude of clinical improvement strongly correlated with the reduction of total sebum lipids (p = 0.0009, r2 = 0.81) and free fatty acids (p = 0.0003, r2 = 0.82). In a further study, a 40-year-old female with mild disseminated sebaceous gland hyperplasia and seborrhea, responded with normalization of the casual skin surface lipids and similar reduction of facial sebum synthesis under treatment with

    Acne vulgaris is the most common skin disorder, and is caused by Propionibacterium acnes (P. acnes) and can induce inflammation. Antibiotic therapy often needs to be administered for long durations in acne therapy, which results in extensive antibiotic exposure. The present study investigated a new treatment model for evaluating the antibacterial effects of lysozyme (LY)-shelled microbubbles (MBs) and ultrasound (US)-mediated LY-shelled MBs cavitation against P. acnes both in vitro and in vivo, with the aims of reducing the dose and treatment duration and improving the prognosis of acne vulgaris. In terms of the in vitro treatment efficacy, the growth of P. acnes was inhibited by 86.08 ± 2.99% in the LY-shelled MBs group and by 57.74 ± 3.09% in the LY solution group. For US power densities of 1, 2, and 3 W/cm(2) in the LY-shelled MBs group, the growth of P. acnes was inhibited by 95.79 ± 3.30%, 97.99 ± 1.16%, and 98.69 ± 1.13%, respectively. The in vivo results showed that the recovery rate on day 13 was higher in the US group with LY-shelled MBs (97.8 ± 19.8%) than in the LY-shelled MBs group (90.3 ± 23.3%). Our results show that combined treatments of US and LY-shelled MBs can significantly reduce the treatment duration and inhibit P.-acnes-induced inflammatory skin diseases.

    Acne is a chronic inflammatory disease of the pilosebaceous unit that affects almost all teenagers. Different treatments offer different modes of action, but aim to target acne pathology. Topical therapies, such as benzoyl peroxide, retinoids, antibiotics with alcohol-based preparations, and salicylic acid, can cause skin irritation resulting in a lack of patient adherence. Some physicians recommend patients use moisturizers as adjunctive treatment of acne, especially when either topical benzoyl peroxide or a retinoid is prescribed. Furthermore, some evidence shows that moisturizers can contribute independently to improve signs and symptoms of acne. Moisturizers contain three main properties, which are occlusive, humectant, and emollient effects. Currently, many moisturizers claim to be suitable for acne treatment. This article aims to provide a review of the active ingredients and properties of those moisturizers. Fifty-two moisturizers for acne were included for analysis. Most of the products (92%) have anti-inflammatory properties apart from occlusive, humectant, and emollient effects. Anti-acne medications, including salicylic acid, benzoyl peroxide, and retinol, were found respectively in 35, 10, and 8 percent of the moisturizer products containing anti-inflammatory properties. More than half of the products contain dimethicone and/or glycerin for its moisturizer property. Aloe vera and witch hazel are botanical anti-inflammatories that were commonly found in this study. Scientific data regarding some ingredients are discussed to provide a guide for physicians in selecting moisturizers for acne patients.

    Background: Scarring following acne vulgaris is common and can be of profound psychosocial consequence. Aims and Objectives: We have clinically noted a variant of acne scarring, overlooked by previous categorisation schemes, which we have denominated as papular acne scars of the nose and chin. We sought to characterise these novel entities further. Materials and Methods: Initially, we identified 14 patients with papular acne scars of the nose and chin in a cosmetic dermatology clinic, of whom two were female and rest were male. We then prospectively evaluated 100 consecutive patients attending our tertiary referral acne isotretinoin clinic and 49 patients attending a general dermatology clinic. Results: Amongst 149 patients, from a general dermatology and tertiary acne clinic, soft papular scars were noted in four patients, distributed on the nose and chin. Three of the four patients were male, three patients had additional acne scars and the median age was 23.5. Conclusions: We have identified 18 patients with papular acne scars of the nose and chin and propose that this new category should be added to acne scarring classification schemes. Future work should be directed at corroborating the epidemiology of such lesions and describing effective treatment modalities. PMID:28163455

    Acne has a prevalence of over 90% among adolescents and persists into adulthood in approximately 12%–14% of cases with psychological and social implications. Possible outcomes of the inflammatory acne lesions are acne scars which, although they can be treated in a number of ways, may have a negative psychological impact on social life and relationships. The main types of acne scars are atrophic and hypertrophic scars. The pathogenesis of acne scarring is still not fully understood, but several hypotheses have been proposed. There are numerous treatments: chemical peels, dermabrasion/microdermabrasion, laser treatment, punch techniques, dermal grafting, needling and combined therapies for atrophic scars: silicone gels, intralesional steroid therapy, cryotherapy, and surgery for hypertrophic and keloidal lesions. This paper summarizes acne scar pathogenesis, classification and treatment options. PMID:20981308

  4. Oral contraceptives in the treatment of acne.

    PubMed

    Tan, J K; Degreef, H

    2001-02-01

    Oral contraceptives (OCs) can reduce acne by lowering the production of adrenal and ovarian androgens, by inhibiting 5-alpha-reductase, which in turn, reduces the levels of dihydrotestosterone, and by stimulating sex hormone binding globulin (SHBG), thus reducing the levels of free testosterone. In newer OCs, such as Tricyclen and Diane-35, the progestin component is minimally androgenic and anti-androgenic respectively, thereby enhancing the favorable profile of these products in the treatment of hyperandrogenic disorders, including acne. The efficacy of these agents and their long-term safety profile supports their use in various grades of acne in females: * As adjunctive therapy to topical agents for women with mild non-scarring acne desiring oral contraception * As primary therapy for patients with moderate non-scarring acne in combination with topical therapy and systemic antibiotics * As one of two preferred methods of contraception in patients with scarring and severe inflammatory acne being treated with systemic isotretinoin.

    Clindamycin 1%/benzoyl peroxide 5% (BenzaClin) is a combination gel indicated for use twice daily, or as directed by a physician, for the topical treatment of inflammatory and noninflammatory lesions of acne vulgaris. In well designed clinical trials in patients with mild to moderately severe acne, the efficacy of once- or twice-daily clindamycin/benzoyl peroxide in the reduction of inflammatory lesion counts was greater than that of benzoyl peroxide alone, clindamycin alone, or tretinoin plus clindamycin, and not significantly different from that of erythromycin/benzoyl peroxide. In the reduction of noninflammatory lesion counts, the efficacy of once- or twice-daily clindamycin/benzoyl peroxide was greater than that of clindamycin alone, but not significantly different to that observed with benzoyl peroxide, tretinoin plus clindamycin, or erythromycin/benzoyl peroxide. Clindamycin/benzoyl peroxide has a fairly rapid onset of action, with acne improvement usually recorded within 2-4 weeks. Despite widespread use, bacterial resistance is not associated with clindamycin/benzoyl peroxide. The product is generally well tolerated, and the main treatment-related adverse events in clinical trials were application-site dryness, irritation, peeling, and erythema. Thus, clindamycin/benzoyl peroxide is an effective and well tolerated option for the management of mild to moderately severe acne.

Prevention is a very important part of comedone treatment, especially avoidance of picking, moisturizers and harsh soaps. Instruments are also very important: even the finest may be too thick and may have to be filed down. Acne surgery is only an adjunct of good medical therapy.

    The moisture content present in human skin makes it look young and the use of moisturizer results in fastening the moisture with a surface film of oil. Acne vulgaris is one of the most commonly seen diseases among the youth. The present study is focused on the use of herbs as moisturizer for acne treatment. The anti-acne moisturizer was formulated from herbal crude extracts and investigated the physico-chemical parameters as well as antibacterial activity of the formulation. The study revealed that ethanol extract of Andrographis paniculata, Glycyrrhiza glabra, Ocimum sanctum, Azadiracta indica and Green tea possessed the potential for inhibiting acne. It was observed that the optimal formula of anti-acne moisturizer was satisfactorily effective to control acne inducing bacteria i.e., Staphylococcus epidermis and Propionibacterium. The physico-chemical parameters of the formulation were also optimal with no signs of irritation.

    Propionibacterium acnes has been implicated as a cause of infection following shoulder surgery, may occur up to 2 years after the index operation and has been shown to be responsible for up to 56% of shoulder infections after orthopedic implant. Male patients within the population undergoing shoulder surgery are particularly at risk, especially if their shoulder surgery involved prosthesis or was posttraumatic. P. acnes infection can be difficult to diagnose clinically and laboratory techniques require prolonged and specialized cultures. Usual inflammatory markers are not raised in infection with this low virulence organism. Delayed diagnosis with P. acnes infection can result in significant morbidity prior to prosthesis failure. Early diagnosis of P. acnes infection and appropriate treatment can improve clinical outcomes. It is important to be aware of P. acnes infection in shoulder surgery, to evaluate risk factors, to recognize the signs of P. acnes infection, and to promptly initiate treatment. The signs and symptoms of P. acnes infection are described and discussed. Data were collected from PubMed™, Web of Science, and the NICE Evidence Healthcare Databases - AMED (Ovid), BNI (Ovid), CINAHL (EBSCO), Embase (Ovid), HMIC: DH-Data and Kings Fund (Ovid), Medline (Ovid), and PsycINFO (Ovid). The search terms used were “P. acnes,” “infection,” “shoulder,” and “surgery.” In this review, we summarize the current understanding of the prevention and management of P. acnes infection following shoulder surgery.

    The recent innovative interventions in the acnes (acne vulgaris, acne rosacea and acne inversa) have not occurred in their management; rather the major changes are occurring in how the disorders and the individual lesions are seen to originate and develop. To finalize the optimal management of each of the acnes will ultimately require that every step in the aetiopathogenesis described and postulated here will need to be tested, validated, and then appropriately countered with environmental and lifestyle adjustments that will lead ultimately to prevention of 'the blight of youth' and its variants.

  13. The mechanisms of action of nicotinamide and zinc in inflammatory skin disease.

    PubMed

    2006-01-01

    Nicotinamide (niacinamide), a physiologically active form of niacin (nicotinic acid), in combination with zinc is being assessed in clinical studies for the treatment of inflammatory skin diseases such as acne vulgaris and bullous pemphigoid. The basis for these investigations is the variety of potential mechanisms of action of nicotinamide and zinc, including an anti-inflammatory effect via inhibition of leukocyte chemotaxis, lysosomal enzyme release, lymphocytic transformation, mast cell degranulation, bacteriostatic effect against Propionibacterium acnes, inhibition of vasoactive amines, preservation of intracellular coenzyme homeostasis, and decreased sebum production. Other possible mechanisms involve suppression of vascular permeability and inflammatory cell accumulation, as well as protection against DNA damage. The goal of this paper is to review the pathophysiology of inflammatory skin diseases and discuss the role, mechanisms of action, and safety of nicotinamide and zinc as therapeutic options for these disorders.

  14. Nanoparticle Stabilized Liposomes for Acne Therapy

    NASA Astrophysics Data System (ADS)

    Fu, Victoria

    Acne vulgaris is a common skin disease that affects over 40 million people in the United States alone. The main cause of acne vulgaris is Propionibacterium acnes (P. acnes), resides deep in the pores and follicles of the skin in order to feed on oil produced by the sebaceous glands. The liposome is a lipid based nanoparticle with numerous advantages over free drug molecules as an acne treatment alternative. Bare liposomes loaded with lauric acid (LipoLA) were found to show strong antimicrobial activity against P. acnes while generating minimal toxicity. However, the platform is limited by the spontaneous tendency of liposomes to fuse with each other. Attaching nanoparticles to the surface of liposomes can overcome this challenge by providing steric repulsion and reduce surface tension. Thus, carboxyl-functionalized gold nanoparticles (AuC) were attached to the surface of liposomes (AuC-liposomes) loaded with doxycycline, a general tetracycline antibiotic. These particles were found to have a diameter of 120 nm and a zeta potential of 20.0 mV. Both fluorescent and antimicrobial studies demonstrated that based on electrostatic interaction, negatively charged AuC attached to the liposome's positively charged surface and stabilized liposomes in a neutral pH environment (pH = 7.4). Upon entering the skin's acidic environment (pH = 4), AuC detached from the liposome's surface and liposomes could fuse with P. acnes residing in the pores. Furthermore, toxicity studies showed that AuC-liposomes did not induce any significant toxicity, while two of the leading over-the-counter therapies, benzoyl peroxide and salicylic acid, generated substantial skin irritation.

    Acne fulminans is a syndrome of sudden onset hemorrhagic and ulcerative acne involving the back, chest, and face combined with systemic symptoms. It can be the dermatologic manifestation of the synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome. Current therapy for acne fulminans consists of wound care, topical and systemic corticosteroids, isotretinoin, and nonsteroidal anti-inflammatory drugs (NSAIDs). Infliximab, a recently developed monoclonal antibody against tumor necrosis factor-alfa, has shown efficacy in the treatment of psoriatic arthritis and ankylosing spondylitis both of which share clinical similarities to the SAPHO syndrome. We report the case of a patient with the SAPHO syndrome and acne fulminans who was treated with infliximab. Ten months after initiating therapy with infliximab, the area of the patient's ulcerative lesions was reduced by 70%. Infliximab might be considered as a treatment option for patients with acne fulminans unresponsive to conventional therapies.

    The human skin harbors a diverse community of bacteria, including the Gram-positive, anaerobic bacterium Propionibacterium acnes. P. acnes has historically been linked to the pathogenesis of acne vulgaris, a common skin disease affecting over 80% of all adolescents in the US. To gain insight into potential P. acnes pathogenic mechanisms, we previously sequenced the complete genome of a P. acnes strain HL096PA1 that is highly associated with acne. In this study, we compared its genome to the first published complete genome KPA171202. HL096PA1 harbors a linear plasmid, pIMPLE-HL096PA1. This is the first described P. acnes plasmid. We also observed a five-fold increase of pseudogenes in HL096PA1, several of which encode proteins in carbohydrate transport and metabolism. In addition, our analysis revealed a few island-like genomic regions that are unique to HL096PA1 and a large genomic inversion spanning the ribosomal operons. Together, these findings offer a basis for understanding P. acnes virulent properties, host adaptation mechanisms, and its potential role in acne pathogenesis at the strain level. Furthermore, the plasmid identified in HL096PA1 may potentially provide a new opportunity for P. acnes genetic manipulation and targeted therapy against specific disease-associated strains.

    Atrophic scarring is often an unfortunate and permanent complication of acne vulgaris. It has high prevalence, significant impact on quality of life, and therapeutic challenge for dermatologists. The treatment of atrophic acne scars varies depending on the types of acne scars and the limitations of the treatment modalities in their ability to improve scars. Therefore, many options are available for the treatment of acne scarring, including chemical peeling, dermabrasion, laser treatment, punch techniques, fat transplantation, other tissue augmenting agents, needling, subcision, and combined therapy. Various modalities have been used to treat scars, but limited efficacy and problematic side effects have restricted their application. In order to optimally treat a patient’s scar, we need to consider which treatment offers the most satisfactory result. There are also promising procedures in the future, such as stem cell therapy. In this article, the authors review the different treatment options of atrophic acne scars. This may be useful for selecting the best therapeutic strategy, whether it be single or combined therapy, in the treatment of atrophic acne scars while reducing or avoiding the side effects and complications.

    Results of clinical trials have shown that tazarotene cream used as monotherapy effectively reduces the number of both inflammatory and noninflammatory lesions in patients with acne vulgaris. The efficacy of tazarotene cream in clinical practice, however, has not been reported. To evaluate the benefits of tazarotene cream in everyday clinical practice, an uncontrolled observational study was conducted in a large population of patients with facial acne vulgaris; 243 investigators enrolled 1118 patients for treatment with once-daily tazarotene 0. 1% cream as monotherapy, or in combination with other agents, for up to 12 weeks. Tazarotene efficacy was well rated by both investigators and patients and had a rapid onset of action. Reduction in comedone counts was greatest when tazarotene 0.1% was used as first-line therapy. The incidence of adverse events (almost exclusively peeling, erythema, dryness, or burning) was low and typically declined with continued use of the medication. The combination of tazarotene 0.1% cream and clindamycin-benzoyl peroxide was the best tolerated of all the treatment regimens. Patients and investigators reported high levels of treatment satisfaction with topical tazarotene 0.1% cream.

At the end of the test period there was no significant difference in the reduction of inflammatory and noninflammatory lesion counts achieved by Nels cream and benzoyl peroxide. Both creams proved superior to the vehicle. Efficacy grading by subjects and investigators showed no significant difference between Nels cream and benzoyl peroxide. However, side-effects such as peeling and dryness caused by the treatment were significantly less in the Nels cream group.

    Zouboulis, Christos C; Piquero-Martin, Jaime

    2003-01-01

    Systemic treatment is required in patients with moderate-to-severe acne, especially when acne scars start to occur. Antibiotics with anti-inflammatory properties, such as tetracyclines (oxytetracycline, tetracycline chloride, doxycycline, minocycline and limecycline) and macrolide antibiotics (erythromycin and azithromycin) are the agents of choice for papulopustular acne, even though the emerging resistant bacterial strains are minimizing their effect, especially regarding erythromycin. Systemic antibiotics should be administered during a period of 8-12 weeks. In severe papulopustular and in nodulocystic/conglobate acne, oral isotretinoin is the treatment of choice. Hormonal treatment represents an alternative regimen in female acne, whereas it is mandatory in resistant, severe pubertal or post-adolescent forms of the disease. Compounds with anti-androgenic properties include estrogens combined with progestins, such as ethinyl estradiol with cyproterone acetate, chlormadinone acetate, desogestrel, drospirenone, levonogestrel, norethindrone acetate, norgestimate, and other anti-androgens directly blocking the androgen receptor (flutamide) or inhibiting androgen activity at various levels, corticosteroids, spironolactone, cimetidine, and ketoconazole. After 3 months of treatment control of seborrhea and acne can be obtained. Low-dose corticosteroids (prednisone, prednisolone, or dexamethasone) are indicated in patients with adrenal hyperandrogenism or acne fulminans. New developments and future trends represent low-dose long-term isotretinoin regimens, new isotretinoin formulations (micronized isotretinoin), isotretinoin metabolites, combination treatments to reduce toxicity, insulin-sensitizing agents, 5alpha-reductase type 1 inhibitors, antisense oligonucleotide molecules, and, especially, new anti-inflammatory agents, such as lipoxygenase inhibitors.

    Acne is a chronic inflammatory disease whose psychosocial effects can greatly impair quality of life. Various scales are used to classify the severity of acne, and several treatment algorithms are currently applied: no consensus on a common scale or treatment guidelines has been reached. A group of Spanish experts therefore met to identify a scale the majority could accept as the most appropriate for classifying severity and treating accordingly. The group chose the following classifications: comedonal acne, mild or moderate papulopustular acne, severe papulopustular acne, moderate nodular acne, and nodular-cystic acne (or acne tending to leave scars). Consensus was reached on first- and second-choice treatments for each type and on maintenance treatment. The experts also issued specific recommendations on antibiotic use (starting with mild or moderate papulopustular acne), always in combination with retinoids and/or benzoyl peroxide. The use of isotretinoin (starting at severe papulopustular or moderate nodular acne) was also covered.

  4. The Role of Inflammation in the Pathology of Acne

    PubMed Central

    2013-01-01

    The conventional perspective of acne pathogenesis holds that Propionibacterium acnes colonizes the duct of the sebaceous follicle, causing an innate immune response and the progression from a so-called noninflammatory comedo to an inflammatory papule, pustule, or nodule. However, this viewpoint has come under increasing scrutiny over the last decade, as evidence has emerged supporting a role for inflammation at all stages of acne lesion development, perhaps subclinically even before comedo formation. The immunochemical pathways underlying the initiation and propagation of the inflammation in acne are complex and still being elucidated, but may involve Propionibacterium acnes as well as several inflammatory mediators and their target receptors, including cytokines, defensins, peptidases, sebum lipids, and neuropeptides. This review presents evidence to support the notion that acne is primarily an inflammatory disease, challenging the current nomenclature of noninflammatory versus inflammatory acne lesions and suggesting that the nomenclature is outdated and incorrect. The evidence in support of acne as an inflammatory disease also has clinical implications, in that anti-inflammatory drugs used to treat the disease can be expected to exert effects against all lesion stages, albeit via distinct mechanisms of anti-inflammation.

    Acne, one of the most common dermatological diseases, is characterized by inflammatory and noninflammatory lesions that may progress to scars. Starting from pubertal age groups, it can affect adults in the age group 35-40 or more. The conventional therapies for treatment of acne are facing roadblocks because of the antibiotic resistance developing against Propionibacterium acnes. This has led to trying new therapies, of which photodynamic therapy (PDT) seems to be the one under intensive study. Promising results have been observed with PDT use in acne treatment, but it still has some more way to go to acquire the FDA approval for use in acne treatment. This is a review of the literature of use of PDT in treatment of acne, providing a starting point for dermatologists seeking to treat their patients with acne safely and effectively with this new method.

    It is well known that nitric oxide (NO) plays an important role in the pathogenesis of inflammatory diseases. Eucalyptus globulus Labill. and Thymus vulgaris L. have been used in traditional medicine in the treatment of bronchitis, asthma and other respiratory diseases. The present study focuses on the effects of these two extracts on NO production induced by lipopolysaccharide (LPS) and interferon-gamma (IFN-gamma) in the murine macrophage cell line J774A.1. In addition, cell viability, scavenging activity and inducible nitric oxide synthase (iNOS) mRNA expression were evaluated. E. globulus and T. vulgaris extracts significantly inhibited the enhanced production of NO induced by LPS and IFN-gamma in a dose-dependent manner. Treatment with these two extracts did not reduce cell viability at any dose used. Both plant extracts showed significant scavenging of NO radicals released by an NO donor, PAPA-NONOate. Results also show that pre-treatment with E. globulus and T. vulgaris extracts significantly inhibits iNOS mRNA expression. This study thus suggests that the inhibition of net NO production by these two extracts may be due to their NO scavenging activity and/or their inhibitory effects on iNOS gene expression.

    The authors have studied the androgenic patterns in 29 women with late-onset persistent acne vulgaris. Clinical evaluation of acne, menstrual history and serum determinations of SHBG, total-T, free-T, DHEAS, delta 4A have been carried out. A mild and heterogeneous hyperandrogenism was found in 70% of women, thus, a greater steroid bioavailability for peripheral conversion and/or a direct stimulation of the pilosebaceous unit can be postulated. Androgenic evaluation in women with late-onset or persistent acne vulgaris is useful, mainly for hormonal management.

    Acne is a genetic, hormonal disease characterized by overproduction of oil by the sebaceous glands, plugging of the sebaceous glands to form micro- and macro- comedons and, finally, action of skin bacteria on oil trapped underneath the skin to red inflammatory cystic lesions. It was shown, that Propionibacterium acnes, the bacteria responsible for acne, was rather subjected to action of red and infrared radiation. The effect of the given radiation amplified at this bacteria by various solutions of photosensitizes.

    Calluna vulgaris L. (Ericaceae) is used for the treatment of various inflammatory ailments in traditional medicines. In order to evaluate this ethnobotanical information, its anti-inflammatory and antinociceptive activities were studied using in vivo experimental models in mice. The ethanolic extract of the plant was first fractionated into five extracts; namely, n-hexane, chloroform, ethyl acetate (EtOAc), n-butanol, and water fractions. Among them, the EtOAc Fr. was found to be the most effective and was further subjected to bioassay-guided fractionation and isolation procedures. After successive column chromatography applications, on Sephadex LH-20 and silica gel, a component, which is responsible for the above-mentioned activities of this species of Turkish origin, was isolated and its structure was elucidated as kaempferol-3-O-beta-D-galactoside, a common flavonol derivative by means of spectral techniques.

    Acne vulgaris (acne) is a common affliction in adolescence and is a growing problem in adult women. Despite an increasing awareness of acne in the adult female population, there is a lack of good prospective studies assessing the severity, distribution, and differential response to treatment in this group. The long-held dogma that acne in adult women develops on the lower one-third of the face has been recently challenged, and here the authors critically review data from available literature. Moreover, while adult female acne has traditionally been defined as disease in women over age 25, it is the authors’ experience that this group is subdivided into women ages 25 to 44 years, separate from perimenopausal patients, ages 45 years and up. While there is no data specifically comparing these two groups, the authors will review the existing data and provide practical recommendations based on our experience in treating these groups of patients. Finally, while there is a lack of data on this subject, it is the group’s opinion that adherence to medication regimens is likely higher in women than men, which influences therapeutic outcomes.

    We report on photodynamically induced inactivation of the skin bacterium Propionibacterium acnes (P. acnes) using endogenous as well as exogenous photosensitizers and red light sources. P. acnes is involved in the pathogenesis of the skin disease acne vulgaris. The skin bacterium is able to synthesize the metal-free fluorescent porphyrins protoporphyrin IX (PP) and coproporphyrin (CP) as shown by in situ spectrally-resolved detection of natural autofluorescence of human skin and bacteria colonies. These naturally occurring intracellular porphyrins act as efficient endogenous photosensitizers. Inactivation of P. acnes suspensions was achieved by irradiation with He-Ne laser light in the red spectral region (632.8 nm). We monitored the photodynamically-induced death of single bacteria using a fluorescent viability kit in combination with confocal laser scanning microscopy. In addition, the photo-induced inactivation was calculated by CFU (colony forming units) determination. We found 633 nm-induced inactivation (60 mW, 0.12 cm2 exposure area, 1 hour irradiation) of 72% in the case of non-incubated bacteria based on the destructive effect of singlet oxygen produced by red light excited endogenous porphyrins and subsequent energy transfer to molecular oxygen. In order to achieve a nearly complete inactivation within one exposure procedure, the exogenous photosensitizer Methylene Blue (Mb) was added. Far red exposure of Mb-labeled bacteria using a krypton ion laser at 647 nm and 676 nm resulted in 99% inactivation.

    Differentiating inflammatory and non-inflammatory acne lesions and obtaining lesion counts is pivotal part of acne evaluation. Manual lesion counting has reliably demonstrated the clinical efficacy of anti-acne products for decades. However, maintaining assessment consistency within and across acne trials is an important consideration since lesion counting can be subjective to the individual evaluators, and the technique has not been rigorously standardized. VISIA-CR is a multi-spectral and multi-modal facial imaging system. It captures fluorescence images of Horn and Porphyrin, absorption images of Hemoglobin and Melanin, and skin texture and topography characterizing broad-spectrum polarized and non-polarized images. These images are analyzed for auto-classification of inflammatory and non-inflammatory acne lesion, measurement of erythema, and post-acne pigmentation changes. In this work the accuracy of this acne lesion auto-classification technique is demonstrated by comparing the auto-detected lesions counts with those counted by expert physicians. The accuracy is further substantiated by comparing and confirming the facial location and type of every auto-identified acne lesion with those identified by the physicians. Our results indicate a strong correlation between manual and auto-classified lesion counts (correlation coefficient >0.9) for both inflammatory and non inflammatory lesions This technology has the potential to eliminate the tedium of manual lesion counting, and provide an accurate, reproducible, and clinically relevant evaluation of acne lesions. As an aid to physicians it will allow development of a standardized technique for evaluating acne in clinical research, as well as accurately choosing treatment options for their patients according to the severity of a specific lesion type in clinical practice

    Acne and rosacea compromise a substantial portion of the dermatology clinical practice. Over the past century, many treatment modalities have been introduced with antibiotics playing a major role. Today, both oral and topical antibiotics are used in the management of acne and rosacea, with several novel formulations and/or combination regimens recently introduced. The latest studies suggest anti-inflammatory actions to be the most likely mechanism of antibiotics in acne and rosacea, shifting the focus to subantimicrobial-dose oral antibiotics and/or topical antibiotic regimens as the preferred first-line agents. Here we will discuss the most recent oral and topical antibiotic therapies available for treatment of acne and rosacea, with special focus on efficacy data, indication, dosing, and mechanism of action.

    There are four central factors that contribute to acne physiopathology: the inflammatory response, colonization with Propionibacterium acnes, increased sebum production and hypercornification of the pilosebaceous duct. In addition, research in the areas of diet and nutrition, genetics and oxidative stress is also yielding some interesting insights into the development of acne. In this paper we review some of the most recent research and novel concepts revealed in this work, which has been published by researchers from diverse academic disciplines including dermatology, immunology, microbiology and endocrinology. We discuss the implications of their findings (particularly in terms of opportunities to develop new therapies), highlight interrelationships between these novel factors that could contribute to the pathology of acne, and indicate where gaps in our understanding still exist.

    Benzoyl peroxide is one of the most widely used topical agents for acne. It has potent antibacterial and mild anti-inflammatory and comedolytic effects. To treat mild to moderate acne, it can be used alone or in combination with topical antibiotics and topical retinoids. The combination of benzoyl peroxide with either erythromycin or clindamycin is synergistic and well-tolerated. In more severe acne, when oral antibiotics are required, benzoyl peroxide can contribute to suppressing the emergence of resistant strains of Propionibacterium acnes.

    Acne is a common skin condition present predominantly in the adolescent population, but may continue into adulthood. Scarring occurs commonly as a sequel to severe inflammatory acne. The presence of acne and resultant scars are more than cosmetic, with a significant potential to alter quality of life and even job prospects. The psychosocial effects of acne and scars can be disturbing and may be a risk factor for serious psychological concerns. Treatment efficacy is generally determined based on an invalidated gestalt by the physician and patient. However, the validated assessment of acne can be challenging and time consuming. Acne can be classified into several morphologies including closed comedones (whiteheads), open comedones (blackheads), papules, pustules, cysts (nodules) and scars. For a validated assessment, the different morphologies need to be counted independently, a method that is far too time consuming considering the limited time available for a consultation. However, it is practical to record and analyze images since dermatologists can validate the severity of acne within seconds after uploading an image. This paper covers the processes of region-ofinterest determination using entropy-based filtering and thresholding as well acne lesion feature extraction. Feature extraction methods using discrete wavelet frames and gray-level co-occurence matrix were presented and their effectiveness in separating the six major acne lesion classes were discussed. Several classifiers were used to test the extracted features. Correct classification accuracy as high as 85.5% was achieved using the binary classification tree with fourteen principle components used as descriptors. Further studies are underway to further improve the algorithm performance and validate it on a larger database.

    Combination therapy using medications with complementary mechanisms of action is the standard of care in treating acne. We report results of a clinical trial evaluating the use of a fixed-dose tretinoin 0.025%/clindamycin phosphate 1.2% (T/CP) gel in combination with a benzoyl peroxide 6% foaming cloth compared with T/CP alone for facial acne. At week 12, the combination therapy group showed a trend toward greater efficacy compared with T/CP alone. There was a high success rate observed in the study, which may be attributable to the large percentage of adult female acne patients enrolled. Cutaneous adverse events were not statistically different in using combination therapy compared with T/CP alone.

    Acne is affecting an increasing number of adult females and so can no longer be considered as a disease of adolescence. The disease has a greater negative impact on the quality of life of adult females than their younger counterparts. Adult female acne may persist from adolescence or may have its first occurrence once adulthood has been reached. The clinical presentation and pathogenesis of adult female acne may be somewhat different to that of adolescent acne and this may require a different treatment approach. Genetic and hormonal factors are thought to play key roles in the pathogenesis of adult female acne and the disease is characterized by a chronic evolution with frequent relapses requiring long-term maintenance therapy. Fixed-dose retinoid/antimicrobial combinations may be of interest for the treatment of adult female acne given that subgroup analysis of clinical trials has indicated that they are effective against both inflammatory and non-inflammatory lesions in these patients. These treatments may also be of interest, given the chronic course of the disease in adult females, the high likelihood of the presence of antibiotic-resistant P. acnes and the poor adherence of patients to other long-term therapies. Oral hormonal treatment or isotretinoin may be required in patients with severe acne or disease that is refractory to other treatments. Additional clinical studies of acne treatments specifically conducted in adult female patients are required to increase the evidence base on which future treatment recommendations can be based.

    In severe cystic acne we found low levels of high density lipoprotein-cholesterol (HDL-C) and apolipoprotein A (Apo-A) in the presence of normal total lipids. In a larger number of patients, we always observed significantly lower levels of HDL-C and Apo-A than in either age-matched controls or subjects with acne vulgaris. Since lipoprotein lipase is one major determinant of HDL concentration, we assayed the lipase activity in liver and extra-hepatic tissues by the method of Krauss et al. There was highly significant less total and hepatic lipase activity than in age-matched controls. HDL distribution was examined by zonal ultracentrifugation and a decrease in the HDL2 subclass was discovered. Since HDL are inversely correlated to atherosclerosis, cystic acne is one risk factor for atherosclerosis. The linkage between low HDL levels and severe cystic acne should be further investigated.

    Acne vulgaris is a chronic inflammatory disease, and its treatment is challenging due to the multifactorial etiology and emergence of antibiotic-resistant Propionibacterium acnes strains. This study was focused to reduce antibiotics usage and find an alternate therapeutic source for treating acne. Lipid extracts of six Chlorella species were tested for inhibition of lipase, reactive oxygen species (ROS) production, cytokine production using P. acnes (Microbial Type Culture Collection 1951). Lipase inhibitory assay was determined by dimercaprol Tributyrate - 5, 5'- dithiobis 2-nitrobenzoic acid method and ROS production assay was performed using nitro-blue tetrazolium test. The anti-inflammatory activity of algal lipid extracts was determined by in vitro screening method based on inhibition of pro-inflammatory cytokines, tumor necrosis factor-alpha (TNF-α) produced by human peripheral blood mononuclear cells. Minimum inhibitory concentration (MIC) values of lipid extracts were determined by microdilution method, and the fatty acid methyl esters (FAME) were analyzed by gas chromatography-mass spectroscopy. Chlorella ellipsoidea has the highest lipase inhibitory activity with 61.73% inhibition, followed by Chlorella vulgaris (60.31%) and Chlorella protothecoides (58.9%). Lipid extracts from C. protothecoides and C. ellipsoidea has significantly reduced the ROS production by 61.27% and 58.34% respectively. Inhibition of pro-inflammatory cytokines TNF-α showed the inhibition ranging from 58.39% to 78.67%. C. vulgaris has exhibited the MICvalue of 10 μg/ml followed by C. ellipsoidea, C. protothecoides and Chlorella pyrenoidosa (20 μg/ml). FAME analysis detected 19 fatty acids of which 5 were saturated fatty acids, and 14 were unsaturated fatty acids ranging from C14 to C24. The results suggest that lipid extracts of Chlorella species has significant inhibitory activity on P. acnes by inhibiting lipase activity. Further, anti-inflammatory reaction caused by the

    Acne vulgaris is the most common skin diseases that people experience during their lives. Thirteen rhizosphere isolates were screened against Propionibacterium acnes. The bacterium exhibited the highest activity against P. acnes was identified as Bacillus methylotrophicus YML008 by 16S rRNA gene sequencing. Scanning electron microscopy was used to assess the changes in morphology of P. acnes. Preliminary studies on the antimicrobial substance demonstrated the hydrophilic nature of compound with MIC of 0.17mg/ml and MBC of 0.3mg/ml. The cytotoxic effect of the extract was least (80% survival) as compared to benzyperoxide (40% survival). These results suggest YML008 as a promising bioresource and may be useful as a lead bacterium to develop a new type of anti-acne skin care prep to cure or prevent acne. Further, mechanism of action and proper clinical trials may be promising for this research.

    2006-01-01

    Various skin disorders with an inflammatory component often have been treated with steroids and/or oral antibiotics. However, long-term use of these agents has drawbacks: steroids may induce numerous serious side effects such as hypertension, immunosuppression, and osteoporosis, and overuse of oral antibiotics may contribute to the development of bacterial resistance, as well as to a host of nuisance side effects such as diarrhea, yeast infections, and photosensitivity. As a result, alternative oral treatments, such as nicotinamide, have been investigated. During the past 50 years, many clinical reports have identified nicotinamide as a beneficial agent in the treatment of a variety of inflammatory skin disorders; what's more, its exceptional safety profile at pharmacologic doses makes it a potentially ideal long-term oral therapy for patients with inflammatory skin diseases. A recent large study evaluating nicotinamide for the treatment of acne or rosacea has confirmed the potential benefits of oral nicotinamide as an alternative approach to managing inflammatory lesions associated with acne vulgaris and acne rosacea. This article reviews the substantial number of reports published over the past 50 years that document the clinical utility and safety of oral and topical formulations of nicotinamide for the treatment of a variety of inflammatory skin conditions.

    Skin is an important interface between the host and its environment. Inflammatory dermatoses often have disrupted skin barrier function, rendering patients more susceptible to allergenic triggers leading to an exaggerated immune response. The skin surface lipid film, an important component of the skin barrier, comprises a mixture of keratinocyte and sebaceous gland-derived lipids. Recent evidence demonstrated that defective keratinocyte lipid synthesis predisposes for the development of atopic dermatitis. However, the important role of sebaceous gland-derived lipids in skin inflammatory diseases may be underrecognized. This overview focuses on the importance of the contribution of sebaceous glands to barrier function. Sebaceous gland alteration may play a role in the pathogenesis of common skin diseases including acne vulgaris, atopic dermatitis, psoriasis, rosacea, and seborrheic dermatitis.

    Background Although, melasma is most prevalent among Asian young women, and also darkly pigmented individuals are particularly prone to developing post inflammatory hyperpigmentation, to the best of our knowledge, there are rare or no studies about the association of melasma and Post inflammatory hyperpigmentation. Objectives The aim of this study was to investigate how likely is a melasma patient to developed post inflammatory hyperpigmentation when compared to patients with inflammatory acne lesions who do not have melasma. Patients and Methods This comparative study was conducted on 400 participants, 200 subjects involved with pigmented lesions of melasma and inflammatory acne lesions and200 involved only with inflammatory Acne lesions without melasma. Melasma, acne and post inflammatory hyper pigmentation, if existed, were assessed by a dermatologist, and pigmentation depth was assessed by wood's lamp. Multivariate logistic regression analysis suitable for study design was used to assess the association between melasma and post-acne pigmentation. Results We found out that 24.1% of patients without melasma had post-acne pigmentation compared to 66.8% in melasma group (P < 0.001). The likelihood of observing post-acne pigmentation was found to be nearly six times more in melasma patients versus those without melasma. Association existed after controlling for possible confounders such as melanin score and time length of self-reported sun exposure, and acne severity score. Conclusions Melasma appears to increase the likelihood of post-acne pigmentation. PMID:24349727

    Benzoyl peroxide (BPO), a therapeutic agent for acne vulgaris, was assessed for in vitro antimicrobial activity against Propionibacterium acnes using a novel broth microdilution testing that improved BPO solubility. We searched for a suitable culture medium to measure the minimum inhibitory concentration (MIC) of BPO against P. acnes and finally found the Gifu anaerobic medium (GAM) broth supplemented with 0.1(v/v)% glycerol and 2(v/v)% Tween 80, in which BPO dissolved up to 1250 μg/mL and P. acnes grew well. The MICs and minimum bactericidal concentrations (MBCs) of BPO against 44 clinical isolates of P. acnes collected from Japanese patients with acne vulgaris were determined by our testing method using the supplemented GAM broth. The MICs of BPO were 128 or 256 μg/mL against all isolates of P. acnes regardless of susceptibility to nadifloxacin or clindamycin. The MBCs of BPO were also 128 or 256 μg/mL against the same isolates. Moreover, BPO at the MIC showed a rapid bactericidal activity against P. acnes ATCC11827 in time-kill assay. In conclusion, we could develop a novel assay for the MIC and MBC determinations of BPO against P. acnes, which is reliable and reproducible as a broth microdilution testing and the present results suggest that BPO has a potent bactericidal activity against P. acnes.

    Although acne is not usually considered to be a disorder that affects the elderly, the disorder occurs sufficiently often in mature individuals to be noteworthy. The variety known as 'persisting acne' is, as its name suggests, ordinary acne that continues into adult life. 'Chin acne' is a curious type that occurs premenstrually in mature women, while 'sporadic acne' describes the sudden development of significant acne in later life for no apparent reason. When acne develops in an individual outside the usual susceptible age group precipitating causes such as exposure to comedogenic substances or drugs must be excluded. Similarly, endocrine causes such as androgen-secreting tumors and the administration of anabolic steroids need to be considered. All inflammatory processes are decreased in the elderly and this may be one reason for the persistence and intransigence of acne lesions in older age groups. The principles of treatment of acne in the elderly do not differ from those in other age groups, although the emphasis during counseling needs to focus on explanation and reassurance rather than prognosis. Topical retinoids and benzoyl peroxide easily irritate elderly skin, so azelaic acid and even sulfur preparations are preferable. Low-dose systemic isotretinoin is reported to be helpful to patients in this age group and is certainly worth a trial.

    Acne is treated according to the clinical picture and the pathophysiologically relevant mechanisms, such as seborrhea, follicular hyperkeratosis, P. acnes colonisation,and inflammation. In mild forms of acne, topical therapy is most appropriate. Comedonal acne can be treated with topical retinoids; papulopustular acne with a combination of retinoids and topical antimicrobial substances (benzoyl peroxide, antibiotics, or azelaic acid). Moderate forms or those with extrafacial involvement can be treated with oral antibiotics combined with topical retinoids or benzoyl peroxide. Acne conglobata and other severe manifestations are treated with oral isotretinoin. Women are also treated with oral contraceptives containing anti-androgenic progestins. If inflammation is prominent, initial short term treatment with oral glucocorticoids is helpful. Second-line agents include oral zinc or dapsone. Following successful treatment, topical retinoids are suitable for maintenance therapy.

    Acne is a common skin disease involving colonization with Propionibacterium acnes (P. acnes), hyperproliferation of the follicular epithelium and inflammatory events. Valrubicin is a second-generation anthracycline, non-toxic upon contact, and available in a topical formulation. Valrubicin’s predecessor doxorubicin possesses antibacterial effects and previously we demonstrated that valrubicin inhibits keratinocyte proliferation and skin inflammation suggesting beneficial topical treatment of acne with valrubicin. This study aims to investigate valrubicin’s possible use in acne treatment by testing valrubicin’s antibacterial effects against P. acnes and P. acnes-induced skin inflammation in vitro and in vivo. Valrubicin was demonstrated not to possess antibacterial effects against P. acnes. Additionally, valrubicin was demonstrated not to reduce mRNA and protein expression levels of the inflammatory markers interleukin (IL)-1β, IL-8, and tumor necrosis factor (TNF)-α in vitro in human keratinocytes co-cultured with P. acnes. Moreover, in vivo, valrubicin, applied both topically and intra-dermally, was not able to reduce signs of inflammation in mouse ears intra-dermally injected with P. acnes. Taken together, this study does not support beneficial antibacterial and anti inflammatory effects of topical valrubicin treatment of acne. PMID:26734122

    Acne dysbiosis happens when there is a microbial imbalance of the over-growth of Propionibacterium acnes (P. acnes) in the acne microbiome. In our previous study, we demonstrated that Staphylococcus epidermidis (S. epidermidis, a probiotic skin bacterium) can exploit glycerol fermentation to produce short-chain fatty acids (SCFAs) which have antimicrobial activities to suppress the growth of P. acnes. Unlike glycerol, sucrose is chosen here as a selective fermentation initiator (SFI) that can specifically intensify the fermentation activity of S. epidermidis, but not P. acnes. A co-culture of P. acnes and fermenting S. epidermidis in the presence of sucrose significantly led to a reduction in the growth of P. acnes. The reduction was abolished when P. acnes was co-cultured with non-fermenting S. epidermidis. Results from nuclear magnetic resonance (NMR) analysis revealed four SCFAs (acetic acid, butyric acid, lactic acid, and succinic acid) were detectable in the media of S. epidermidis sucrose fermentation. To validate the interference of S. epidermidis sucrose fermentation with P. acnes, mouse ears were injected with both P. acnes and S. epidermidis plus sucrose or phosphate buffered saline (PBS). The level of macrophage-inflammatory protein-2 (MIP-2) and the number of P. acnes in ears injected with two bacteria plus sucrose were considerably lower than those in ears injected with two bacteria plus PBS. Our results demonstrate a precision microbiome approach by using sucrose as a SFI for S. epidermidis, holding future potential as a novel modality to equilibrate dysbiotic acne. PMID:27834859

    The severity of acne and rate of excretion of sebum were assessed in 243 patients with epilepsy taking various anticonvulsants who were in hospital long term and in matched controls derived from a normal population of 2176 people. Neither the prevalence of acne nor the sebum excretion rate significantly increased in the patients compared with the controls or in patients taking phenytoin compared with those not. It is concluded that anticonvulsant treatment does not cause acne. PMID:6227369

    We report 2 patients with the association of Crohn's disease and acne inversa (= hidradenitis suppurativa). A 50-year-old woman with a 10-year-history of Crohn's disease developed suppurative nodules and abscesses in the genitoanal region. Over several years these lesions were hidden from everybody including the family physician. In a 42-year-old female patient abscesses appeared in the axilla 4 years after the diagnosis of Crohn's disease. During the next years these draining lesions also developed in both groins and the perineum. The differential diagnosis included cutaneous manifestations of Crohn's disease in both cases. The clinical picture with draining abscesses and sinuses with communicating channels, cystic nodules, hypertrophic scars and foul-smelling discharge were typical findings of acne inversa. In the last years this entity was reported several times in patients with Crohn's disease. Acne inversa starts with a compact hyperkeratosis of the infundibulum in terminal hair follicles, followed by a segmental rupture of the follicular epithelium and a spreading inflammatory reaction. As pathogenic factors genetic disposition and smoking were discussed. The only curative therapy is excision of the affected area. The reported association should be known in order to recognize the disease and institute the right therapy.

    Acne is a disfiguring disease, occurring mainly in adolescence. It is a common disorder, affecting above 80% of adolescents in some degree. 50% wish to have treatment for the condition. Acne appears in many forms; from the more common comedonal and papulopustular types to the often devastating cystic and fulminant acne. Some patients develop disfiguring scarring and keloidal reactions, which persist for the rest of their lives. With the treatment facilities available in modern medicine, acne problems can be eliminated through topical and/or systemic treatment options.

    The treatment of acne is based upon simple pathogenic arguments, but needs to be adapted to the type of acne. Patients must always be informed that it is long and difficult and that no significant response will be expected before 2 to 3 months of regular treatment. The authors present the different therapeutic agents and strategies. Isotretinoin should be used only in severe acne after failure of at least 3 months of a well conducted classical treatment and in nodulo-cystic acne; because of its major side effect of teratogenicity its use in adolescent girl's requires pregnancy testings before and during treatment and an effective contraception.

    Underlying hormone imbalances may render acne unresponsive to conventional therapy. Relevant investigations followed by initiation of hormonal therapy in combination with regular anti-acne therapy may be necessary if signs of hyperandrogenism are present. In addition to other factors, androgen-stimulated sebum production plays an important role in the pathophysiology of acne in women. Sebum production is also regulated by other hormones, including estrogens, growth hormone, insulin, insulin-like growth factor-1, glucocorticoids, adrenocorticotropic hormone, and melanocortins. Hormonal therapy may also be beneficial in female acne patients with normal serum androgen levels. An understanding of the sebaceous gland and the hormonal influences in the pathogenesis of acne would be essential for optimizing hormonal therapy. Sebocytes form the sebaceous gland. Human sebocytes express a multitude of receptors, including receptors for peptide hormones, neurotransmitters and the receptors for steroid and thyroid hormones. Various hormones and mediators acting through the sebocyte receptors play a role in the orchestration of pathogenetic lesions of acne. Thus, the goal of hormonal treatment is a reduction in sebum production. This review shall focus on hormonal influences in the elicitation of acne via the sebocyte receptors, pathways of cutaneous androgen metabolism, various clinical scenarios and syndromes associated with acne, and the available therapeutic armamentarium of hormones and drugs having hormone-like actions in the treatment of acne.

    Acne scars can be improved with various treatments such as topical creams, chemical peels, dermal fillers, microdermabrasion, laser, and radiofrequency devices. Some of these treatments especially lasers and deep chemical peels can have significant side effects such as post inflammatory hyperpigmentation in darker skin types. Fraxelated RF Laser devices have been reported to have lower incidence of side effects in all skin phototypes. Nine patients between ages 18 and 35 of various skin phototypes were selected from a private practice and treated with a RF fraxelated device (E-matrix) for acne scars. Outcomes were measured by physician observation, subjective feedback received by patients, and comparison of before and after photographs. In this small group of patients with various skin phototypes, fraxelated radiofrequency device improved acne scars with minimal side effects and downtime.

    Acne is characterized by primary lesions on the face, chest, and back, and by a variety of other signs and symptoms. In particular, acne inflammatory lesions result from Propionibacterium acnes colonization and are of particular relevance as they can cause permanent scarring. Acne also causes significant psychological morbidity in affected patients. Products currently available for the treatment of acne include systemic and topical treatments. As these products can cause severe side effects, new, innovative therapies are needed. Farmaka Acne Cream (FAC) is a novel, film-forming cream developed to treat mild and moderate acne. In vitro studies have demonstrated that FAC is as effective as 5% benzoyl peroxide in inhibiting growth of P. acnes. In 32 subjects with mild or moderate acne, FAC reduced all the major signs and symptoms of the disease. These included itching, erythema, and scaling, as well as reductions in the numbers of papules, pustules, and open and closed comedones. Acne severity improved in 38% of subjects, while none worsened. FAC was found to be effective in controlling sebum secretion, and was non-comedogenic. Most subjects (90%) reported tolerability as good or very good, while clinical efficacy and cosmetic acceptability were judged as good. For assessment of contact sensitization and photosensitization, FAC was applied daily to the backs of 29 subjects in two symmetric areas for 10 days. Using a solar stimulator, one minimal erythema dose was delivered to one side of the back from days 11 to 13. The four different subareas of treated/untreated and irradiated/nonirradiated and combinations thereof were compared. No cases of contact sensitization or photosensitization were observed, and FAC is considered safe for use in intense sunlight. In vitro and in vivo studies provide evidence for the safety and clinical benefits of FAC, a promising candidate for the treatment of mild and moderate acne.

    Acne is a common skin disease in society and often leads to scarring. In this paper, we demonstrate the capabilities of swept-source optical coherence tomography (SS-OCT) in detecting specific features of acne lesion initiation and scarring on human facial skin in vivo over 30 days. Optical microangiography (OMAG) technique made it possible to image 3D tissue microvasculature changes up to 1 mm depth in vivo without the need of exogenous contrast agents in ~10 seconds. The presented results show promise to facilitate clinical trials of treatment and prognosis of acne vulgaris by detecting cutaneous microvasculature and structural changes within human skin in vivo.

    BACKGROUND: Scars appear as a result of skin damage during the process of the skin healing. There are two types of acne scars, depending on whether there is a loss or accumulation of collagen: atrophic and hypertrophic. In 80-90% it comes to scars with loss of collagen compared to smaller number of hypertrophic scars and keloids. AIM: The aim of the study was to determine efficiency and safety of fractional carbon dioxide laser in the treatment of acne scars. MATERIAL AND METHODS: The study was carried out in Acibadem Sistina Clinical Hospital, Skopje at the Department of Dermatovenerology, with a total of 40 patients treated with fractional carbon dioxide laser (Lutronic eCO2). The study included patients with residual acne scars of a different type. RESULTS: Comedogenic and papular acne in our material were proportionately presented in 50% of cases, while the other half were the more severe clinical forms of acne - pustular inflammatory acne and nodulocystic acne that leave residual lesions in the form of second, third and fourth grade of scars. CONCLUSION: The experiences of our work confirm the world experiences that the best result with this method is achieved in dotted ice pick or V-shaped acne scars. PMID:27275326

    Acne vulgaris is the most common condition treated by physicians worldwide. Though most acne patients remit spontaneously, for the ones that do not or are unresponsive to conventional therapy or have obvious cutaneous signs of hyperandrogenism, hormonal therapy is the next option in the therapeutic ladder. It is not strictly indicated for only those patients who have cutaneous or biochemical evidence of hyperandrogenism, but can be used even without any evidence of hyperandrogenism, for therapy-resistant acne. It can be prescribed as monotherapy, but when used in combination with other conventional therapies, it may prove to be more beneficial. Hormonal evaluation is a prerequisite for hormonal therapy, to identify the cause behind hyperandrogenism, which may be ovarian or adrenal. This article reviews guidelines for patient selection and the various available hormonal therapeutic options, their side-effect profile, indications and contraindications, and various other practical aspects, to encourage dermatologists to become comfortable prescribing them.

    Acne vulgaris is classically considered a disease of adolescence. Although it most commonly occurs and has been best studied in that age group, it can develop at any time during childhood. It is important that health care practitioners recognize the manifestations of neonatal, infantile and childhood acne, as well as the differential diagnosis and best therapeutic approach in the younger child. Acneiform eruptions in infants and toddlers can occasionally be associated with scarring or with other significant disorders that may be life-threatening. In this article, the authors draw on their own clinical experience as well as the available literature to suggest an age-based approach to managing acne in children from the neonatal period through age 11 years.

  8. Role of FGFR2-signaling in the pathogenesis of acne

    PubMed Central

    2009-01-01

    It is the purpose of this review to extend our understanding of the fibroblast growth factor (FGF) receptor-2b-signaling network in the pathogenesis of acne. A new concept of the role of FGFR2b-signaling in dermal-epithelial interaction for skin appendage formation, pilosebaceous follicle homeostasis, comedogenesis, sebaceous gland proliferation and lipogenesis is presented. The FGFR2-gain-of-function mutations in Apert syndrome and unilateral acneiform nevus are most helpful model diseases pointing the way to androgen-dependent dermalepithelial FGFR2-signaling in acne. Androgen-mediated upregulation of FGFR2b-signaling in acne-prone skin appears to be involved in the pathogenesis of acne vulgaris. In organotypic skin cultures, keratinocyte-derived interleukin-1α stimulated fibroblasts to secrete FGF7 which stimulated FGFR2b-mediated keratinocyte proliferation. Postnatal deletion of FGFR2b in mice resulted in severe sebaceous gland atrophy. The importance of FGFR2b in sebaceous gland physiology is further supported by the mode of action of anti-acne agents which have been proposed to attenuate FGFR2b-signaling. Downregulation of FGFR2b-signaling by isotretinoin explains its therapeutic effect in acne. Downregulation of FGFR2b-signaling during the first trimester of pregnancy disturbs branched morphogenesis and explains retinoid embryotoxicity. Insulin-like growth factor-1 (IGF-1), the mediator of growth hormone during puberty, intracts with androgen-dependent FGFR2b-signaling and links androgen- and FGF-mediated signal transduction important in sebaceous gland homeostasis. The search for a follicular defect in the dermalepithelial regulation of growth factor-signaling in acne-prone skin appears to be a most promising approach to clarify the pathogenesis of acne.

    This review is an update of the literature accumulated over the past 6 years following the original observation that topically applied azelaic acid, a non-toxic C9 dicarboxylic acid, has a beneficial therapeutic effect on acne vulgaris. These studies have shown that azelaic acid has a modulating influence on the process of keratinization, and that it acts as a keratolytic and anti-comedogenic agent. There is evidence that it inhibits mitochondrial and microsomal oxido-reductases, including 5-alpha-reductase, and that it may interfere with the process of sebogenesis. It has a spectrum of antimicrobial activity, both in vitro and in vivo, against aerobic microorganisms and is effective against the anaerobic Propionibacterium acnes. Extensive multi-centre clinical trials have established that topical azelaic acid (a 20% cream) is an effective treatment for all types of acne. It compares well with other agents, such as topical tretinoin or benzoyl-peroxide, or oral tetracycline. It is non-irritant, and does not give rise to allergic or photo-toxic reactions. Its use is not associated with teratogenicity, possible endocrine unbalance, or the disadvantages of antibiotic treatment. It can be applied for long periods, in recurrences, and as maintenance "spot" therapy against individual lesions.

  10. Sex hormones and acne.

    Ju, Qiang; Tao, Tao; Hu, Tingting; Karadağ, Ayşe Serap; Al-Khuzaei, Safaa; Chen, WenChieh

    The skin is an endocrine organ with the expression of metabolizing enzymes and hormone receptors for diverse hormones. The sebaceous gland is the main site of hormone biosynthesis, especially for androgens, and acne is the classical androgen-mediated dermatosis. In sebocytes, conversion of 17-hydroxyprogesterone directly to dihydrotestosterone bypassing testosterone has been demonstrated, while type II 17β-hydroxysteroid dehydrogenase can inactivate the action of testosterone and dihydrotestosterone. The androgen receptor-dependent genomic effect of dihydrotestosterone on sebocytes is confirmed. Further evidence supports the PI3 K/Akt/FoxO1/mTOR signaling in the involvement of the interplay between androgens, insulin, insulin-like growth factor, and hyperglycemic diet in acne. Androgens not only regulate embryology and lipogenesis/sebum synthesis in sebocytes but also influence inflammation in acne. Genetic studies indicate that regulation of the androgen receptor is an important factor in severe acne. Further studies are required to understand the effect of estrogen and progesterone on sebaceous gland and comedogenesis, considering the change of acne in pregnancy and postmenopausal acne. Special attention should be paid to nonobese patients with polycystic ovarian syndrome and hyperandrogenism-insulin resistance-acanthosis nigricans syndrome. In spite of extensive gynecologic experience in the use of combined oral contraceptives for acne, evidence based on dermatologic observation should be intensified.

    We have recently developed betalain-rich beetroot (Beta vulgaris) dye (betalain) to be used in food products. Betalain (30-300 mg/kg) intraperitoneal (i.p.) treatment diminished carrageenan (100 µg/paw)-induced paw edema and neutrophil migration to the paw skin tissue. Betalain (100 mg/kg) treatment by subcutaneous or per oral routes also inhibited the carrageenan-induced paw edema. Importantly, the post-treatment with betalain (100 mg/kg, i.p.) significantly inhibited carrageenan- and complete Freund's adjuvant (10 µl/paw)-induced paw edema. Betalain (100 mg/kg) also reduced carrageenan (500 µg/cavity)-induced recruitment of total leukocytes, including mononuclear cells and neutrophils, as well as increasing vascular permeability in the peritoneal cavity. Furthermore, betalain significantly reduced carrageenan-induced superoxide anion, tumor necrosis factor-alpha (TNF-α) and interleukin (IL)-1β levels in the peritoneal fluid, as well as augmenting IL-10 levels. Therefore, this compound presents prominent anti-inflammatory effect on carrageenan-induced paw edema and peritonitis by reducing the production of superoxide anion and the cytokines TNF-α and IL-1β, in addition to increasing IL-10 levels. These results suggest that betalain shows therapeutic potential that could be utilized in the treatment of inflammation-associated diseases.

    Fractional microneedling radiofrequency (FMR) is one of the promising methods in acne treatment. Moreover, bipolar radiofrequency (BR) generates heat thereby which induces neocollagenosis. FMR may have the potential to be a safe and effective treatment for the patients both with acne and acne scar. This study was performed to compare the efficacy and safety of FMR and BR in acne and acne scar treatment. Furthermore, mechanism of the FMR treatment was investigated through skin tissues obtained from subjects. Twenty subjects with mild-to-moderate acne and acne scars were treated in a split-face manner with FMR and BR. Two sessions of treatment was done 4 weeks apart in a total 12-week prospective single-blind, randomized clinical trial. Clinical assessment and sebum measurement were carried out for the evaluation of efficacy and safety. Skin tissues were acquired for investigation of molecular changes. FMR was more effective for acne scar especially in icepick and boxcar scar compared to BR. Both inflammatory and non-inflammatory acne lesions decreased by 80 and 65 % in the FMR-treated side at the final visit of 12 weeks, respectively. FMR treatment resulted in significant reduction of sebum excretion. Both treatments showed no severe adverse effects other than erythema. The FMR showed superior efficacy in acne and acne scar compared with BR. Increased expression of TGFβ and collagen I and decreased expression of NF-κB, IL-8 are suggested to involve in the improvement of acne scar and acne lesion by FMR.

    2011-06-01

    Rosacea and acne are chronic inflammatory skin conditions that share an inflammatory pathogenesis, but clinically remain quite distinct. Although many have long assumed that these conditions are primarily infectious, emerging evidence suggests that inflammation plays a critical role in the pathogenesis of these disorders. Part of the innate immune system, the antimicrobial and proinflammatory cathelicidins, may be downregulated by both azelaic acid and sub antimicrobial doxycycline. In acne, the creation of papules, pustules and nodules is clearly mediated through immune mechanisms, and the antiinflammatory effects of retinoids play a key role in management. Recent observations help us understand in greater detail the role that inflammation plays in these two diseases, and the mechanisms by which commonly used medications exert their effect by modulating inflammatory processes. This review will present and synthesize recently acquired information as it relates to inflammatory acne and rosacea pathogenesis and clinical management.

    Viruses specifically infecting bacteria, or bacteriophages, are the most common biological entity in the biosphere. As such, they greatly influence bacteria, both in terms of enhancing their virulence and in terms of killing them. Since the first identification of bacteriophages in the beginning of the 20th century, researchers have been fascinated by these microorganisms and their ability to eradicate bacteria. In this review, we will cover the history of the Propionibacterium acnes bacteriophage research and point out how bacteriophage research has been an important part of the research on P. acnes itself. We will further discuss recent findings from phage genome sequencing and the identification of phage sequence signatures in clustered regularly interspaced short palindromic repeats (CRISPRs). Finally, the potential to use P. acnes bacteriophages as a therapeutic strategy to combat P. acnes-associated diseases will be discussed.

  2. Acne: endocrinologic aspects.

    PubMed

    Pochi, P E

    Acne is dependent for its development on several factors, one of which is hormonal. The principal and possibly sole mechanistic link between hormones and acne is sebum, the secretory product of the sebaceous glands which is highly androgen-sensitive. Some but not all, patients with acne can be shown to have systemic androgen abnormalities. In addition, there is evidence to suggest that androgens are metabolized abnormally in the skin, possibly resulting in excessive sebaceous gland secretion. Systemic endocrine therapy of acne is designed to reduce the androgenic stimulation of the sebaceous gland. Such treatment includes the peroral cyclic administration of estrogen for ovarian inhibition and the use of low-dosage glucocorticoid for adrenocortical androgen suppression. Combined estrogen-glucocorticoid treatment induces the most telling effect in reducing sebaceous gland activity.

  3. The role of antimicrobial peptides in chronic inflammatory skin diseases

    Antimicrobial peptides (AMPs) are effector molecules of the innate immune system of the skin. They present an activity against a broad spectrum of Gram-positive and Gram-negative bacteria as well as some fungi, parasites and enveloped viruses. Several inflammatory skin diseases including psoriasis, atopic dermatitis, acne vulgaris and rosacea are characterized by a dysregulated expression of AMPs. Antimicrobial peptides are excessively produced in lesional psoriatic scales or rosacea in contrast to the atopic skin that shows lower AMP levels when compared with psoriasis. The importance of the AMPs contribution to host immunity is indisputable as alterations in the antimicrobial peptide expression have been associated with various pathologic processes. This review discusses the biology and clinical relevance of antimicrobial peptides expressed in the skin and their role in the pathogenesis of inflammatory skin diseases. PMID:26985172

    Propionibacterium acnes is a skin commensal that occasionally acts as an opportunistic pathogen. The population structure of this species shows three main lineages (I–III). While type I strains are mainly associated with sebaceous follicles of human skin and inflammatory acne, types II and III strains are more often associated with deep tissue infections. We investigated the occurrence and distribution of the clustered regularly interspaced short palindromic repeats (CRISPR) in P. acnes, assessed their immunological memory, and addressed the question if such a system could account for type-specific properties of the species. A collection of 108 clinical isolates covering all known phylotypes of P. acnes was screened for the existence of CRISPR/cas loci. We found that CRISPR loci are restricted to type II P. acnes strains. Sequence analyses of the CRISPR spacers revealed that the system confers immunity to P. acnes-specific phages and to two mobile genetic elements. These elements are found almost exclusively in type I P. acnes strains. Genome sequencing of a type I P. acnes isolate revealed that one element, 54 kb in size, encodes a putative secretion/tight adherence (TAD) system. Thus, CRISPR/cas loci in P. acnes recorded the exposure of type II strains to mobile genetic elements of type I strains. The CRISPR/cas locus is deleted in type I strains, which conceivably accounts for their ability to horizontally acquire fitness or virulence traits and might indicate that type I strains constitute a younger subpopulation of P. acnes.

    Background: Acne vulgaris is the most common skin disease. Local and systemic antimicrobial drugs are used for its treatment. But increasing resistance of Propionibacterium acnes to antibiotics has been reported. Materials and Methods: In a double-blind clinical trial, 40 patients with mild to moderate acne vulgaris were recruited. one side of the face was treated with Clindamycin Gel 1% and the other side with Azithromycin Topical Gel 2% BID for 8 weeks and then they were assessed. Results: Average age was 21. 8 ± 7 years. 82.5% of them were female. Average number of papules, pustules and comedones was similarly reduced in both groups and, no significant difference was observed between the two groups (P > 0.05, repeated measurs ANOVA). The mean indexes of ASI and TLC also significantly decreased during treatment in both groups, no significant difference was observed between the two groups. (P > 0.05, repeated measurs ANOVA). Also, impact of both drugs on papules and pustules was 2-3 times greater than the effect on comedones. Average satisfaction score was not significant between the two groups (P = 0.6, repeated measurs ANOVA). finally, frequency distribution of complications was not significant between the two groups (P > 0.05, Fisher Exact test). Conclusion: Azithromycin gel has medical impact at least similar to Clindamycin Gel in treatment of mild to moderate acne vulgaris, and it may be consider as suitable drug for resistant acne to conventional topical therapy.

  6. The role of benzoyl peroxide in the new treatment paradigm for acne.

    2013-06-01

    Bacterial resistance became a true clinical concern for dermatologists in the 1980s, when the first reports emerged of the resistance of Propionibacterium acnes to oral antibiotics. Subsequent studies have documented acne treatment failure associated with resistance to topical antibiotics. Beyond dermatology practice, antibiotic resistance has now become recognized as a worldwide health concern. In contrast to antibiotics commonly used in the treatment of acne, benzoyl peroxide (BP)'s mechanism of action is different. Benzoyl peroxide is a bactericidal agent. Combining BP with a topical antibiotic in a stable formulation has been proven in clinical trials to reduce total P acnes count by 99.7% after 1 week of therapy, eliminating both susceptible and resistant strains of P acnes. However, we have recently noticed BP's benefits as monotherapy in the treatment of acne. Benzoyl peroxide works rapidly on P acnes without causing antibiotic resistance. Hence, we may have to reconsider the role of topical antibiotics such as clindamycin in the treatment paradigm of acne vulgaris.

    Today, as 40 years ago, we still rely on a limited number of antibiotics and benzoyl peroxide to treat inflammatory acne. An alternative way of suppressing the growth of Propionibacterium acnes is to target the environment in which it thrives. We conjecture that P. acnes colonises a relatively “extreme” habitat especially in relation to the availability of water and possibly related factors such as ionic strength and osmolarity. We hypothesise that the limiting “nutrient” within pilosebaceous follicles is water since native sebum as secreted by the sebaceous gland contains none. An aqueous component must be available within colonised follicles, and water may be a major factor determining which follicles can sustain microbial populations. One way of preventing microbial growth is to reduce the water activity (aw) of this component with a biocompatible solute of very high water solubility. For the method to work effectively, the solute must be small, easily diffusible, and minimally soluble in sebaceous lipids. Xylose and sucrose, which fulfil these criteria, are nonfermentable by P. acnes and have been used to reduce water activity and hence bacterial colonisation of wounds. A new follicularly targeted topical treatment for acne based on this approach should be well tolerated and highly effective. PMID:23762853

    Background: Acne is the most common skin disease, affecting nearly 85% of the population as well as their lives. Acne can severely affect social and psychological functioning. Patients with acne may have anxiety, depression, decreased self-esteem, interpersonal difficulties, unemployment, social withdrawal, and even suicidal intent. Aims: The aim of this study was to evaluate the temperament and character inventory (TCI) of patients with acne and to compare the results with those of healthy controls. Study Design: Case-control study Methods: The study population consisted of 47 patients with acne, and 40 healthy control subjects. All participants were instructed to complete a self-administered 240-item TCI and the Hospital Anxiety and Depression Scale. Results: In this study, the scores for the temperament properties Worry and pessimism (HA1) and Dependence (RD4) and the character properties Social acceptance (C1) and Integrated conscience (C5) were found to be higher in acne patients than in healthy controls (p<0.05). Compared to the controls, depression and anxiety scores were found to be markedly higher in the patients with acne. Acne type correlated positively with the Disorderliness (NS4) subscale of Novelty seeking (NS) and anxiety. Additionally, acne type correlated negatively with the Attachment (RD3) subscale of Reward Dependence (RD), with the Transpersonal identification (ST2) and Spiritual acceptance (ST3) subscales of Self-Trancendence (ST), and with the Compassion (C4) sub-scale of Cooperativeness (C). Conclusion: Studies in this area may lead to the development of specific and focused interventions for TCI in patients with acne vulgaris. We suggest that the evaluation and treatment of acne should also include psychosomatic approaches in clinical practice. PMID:25207094

    Atrophic facial scars which commonly occur after inflammatory acne vulgaris can be extremely disturbing to patients both physically and psychologically. Treatment with fractional laser devices has become increasingly popular, but there has been disappointment in terms of effectiveness. The objective of this study was to assess the safety and efficacy of ablative full-face resurfacing on atrophic acne scars in the Korean population. A total of 22 patients, aged 25-44 years, underwent a new modality of resurfacing combining both short-pulsed and dual-mode erbium:yttrium-aluminum garnet (Er:YAG) laser. The patients had Fitzpatrick skin types ranging from III to V. Photographs were taken before and up to 6 months after treatment. Results were evaluated for the degree of clinical improvement and any adverse events. Degree of improvement was graded using a four-point scale: poor (1) = <25%, fair (2) = 25-50%, good (3) = 51-75%, and excellent (4) = >75%. Based on the blinded photo assessments by two independent reviewers, clinically and statistically significant mean improvement of 3.41 was observed (one-sample Wilcoxon signed rank test, P < 0.001). Complete wound healing occurred between 6 and 9 days. Erythema occurred in all patients and lasted longer than 3 months in two patients (9.1%). Postinflammatory hyperpigmentation occurred in ten patients (45.5%) and lasted longer than 3 months in one patient (4.5%). One patient experienced mild hypopigmentation (4.5%). Mild to moderate acne flare-up occurred in five patients (22.7%). No other adverse effects were observed. A new modality of Er:YAG laser resurfacing combining short-pulsed and dual-mode Er:YAG laser is a safe and very effective treatment modality for atrophic facial acne scars in Asians with darker skin tones.

  10. Oral contraceptives as anti-androgenic treatment of acne.

    PubMed

    Lemay, André; Poulin, Yves

    2002-07-01

    Although acne is seldom associated with high serum levels of androgens, it has been shown that female acne patients have definite increases in ovarian and adrenal androgen levels when compared to appropriate controls. As shown in several pilot and in multiple open and comparative studies, oral contraceptives (OCs) are effective in causing a significant regression of mild to moderate acne. These results have been confirmed by multicentre randomized trials where low-dose OCs did not cause side effects different from those of the placebo-controlled group. The beneficial effect of OCs is related to a decrease in ovarian and adrenal androgen precursors; to an increase in sex hormone-binding globulin (SHBG), which limits free testosterone; and to a decrease in 3a-androstenediol glucuronide conjugate, the catabolite of dihydrotestosterone (DHT) formed in peripheral tissues. The estrogen-progestin combination containing cyproterone acetate (CPA) is particularly effective in treating acne, since this progestin also has a direct peripheral anti-androgenic action in blocking the androgen receptor. Only two open studies and one randomized study on small numbers of patients have reported some efficacy of spironolactone used alone or in combination with an OC in the treatment of acne. The new non-steroidal anti-androgens flutamide and finasteride are being evaluated for the treatment of hirsutism. Oral antibiotics are prescribed to patients with inflammatory lesions, where they are effective in decreasing the activity of microbes, the activity of microbial enzymes, and leukocyte chemotaxis. Concomitant intake of an OC and an antibiotic usually prescribed for acne does not impair the contraceptive efficacy of the OC. A second effective contraceptive method should be used whenever there would be decreased absorption or efficacy of the OC (digestive problems, breakthrough bleeding), lack of compliance and use of a type or dose of antibiotic different from that usually prescribed

  11. The effect of benzoyl peroxide 9.8% emollient foam on reduction of Propionibacterium acnes on the back using a short contact therapy approach.

    Benzoyl peroxide (BP) exerts its therapeutic effect for acne vulgaris through reduction of Propionibacterium acnes. A 1.0 to 2.0 log reduction in P acnes has been demonstrated primarily on the face with use of "leave-on" BP formulations, but also with some BP cleansers. In addition to use for facial acne vulgaris, cleanser formulations of BP are commonly used for truncal acne vulgaris due to ease of use on a large body-surface area and to avoid bleaching of fabric. To date, evaluation of P acnes reduction on the trunk has not been well studied with BP formulations, especially with the use of recognized and standardized methods to accurately determine P acnes colony counts. A previous study demonstrated that a BP 8% cleanser did not reduce counts of P acnes on the back when subjects were instructed to apply the cleanser in the shower, allow it to dry for 20 seconds on the skin, and then rinse off the cleanser. Evaluation of specified time intervals between application on the back and rinsing with BP formulations would help to better define the necessary skin contact time associated with high reductions of P acnes (>90%), recognizing also the potential roles of BP concentration and vehicle. This 2 week study using quantitative bacteriologic cultures evaluates the effectiveness of BP 9.8% emollient foam in reducing P acnes levels on the back with 2 minutes of skin contact time and compares results with a BP 5.3% "leave-on" emollient foam formulation. Short contact therapy utilizing a 2 minute skin contact time with BP 9.8% emollient foam used once daily over a 2 week duration was highly effective in reducing the quantity of P acnes organisms on the back and provided comparable colony count reduction to "leave on" therapy using BP 5.3% emollient foam.

    Cosmetic products contribute to the efficacy of anti-acneic treatment. Cleaning bars without soap and lotions are to be preferred to soaps. Morning application of moisturizing creams compensate for dryness and irritation induced by topical treatment. Some of these cosmetic products may have a limited efficacy of the shiny appearance and/or acne lesions. Scrubs, abrasive sponges, masks and patches have a very limited usefulness. Make up and camouflage techniques are authorized, provided that the products have been tested non comedogenic and non acne-genic.

    2015-01-01

    Acne inversa (hidradenitis suppurativa) is a potentially severe and chronic inflammatory disease with a significant negative influence on the quality of life. Usually, lesions are located in the areas of skin folds and it is characterized by the presence of painful nodules and fistulas with a tendency to tissue fibrosis. Currently, it is suggested that follicular occlusion by infundibular hyperkeratosis plays a crucial role in pathogenesis and an occupation of apocrine sweat glands is a secondary phenomenon. Most often, it refers to men after puberty. This article tries to present the latest theory concerning the etiology of inverted acne and methods of its treatment. It also describes the most common errors in diagnostic and therapeutic procedures, which are mainly connected with repeated and long antibiotic therapy and not radical surgical treatment.

  14. Importance of vehicles in acne therapy.

    PubMed

    Kircik, Leon H

    2011-06-01

    Topiucal drug therapy is an intuitively sound approach to the management of skin diseases. Depositing medication at the site of disease involvement is potentially effective and reduces systemic exposure. Topical drugs are absorbed usually by passive diffusion. In clinical practice, the choice of an optimized formulation that will be effective and well tolerated is essential. Data confirm that patient adherence with therapy leads to better outcomes and lower long-term treatment costs, while poor adherence is directly linked to poor treatment outcomes and and patient dissatisfaction. Local cutaneous irritation, which may be linked to components of the formulation and/or to the active drug itself, is a common cause of non-adherence. Well-designed drugs are important in the management of acne vulgaris and acne rosacea. Formulators have sought to improve treatment efficacy and tolerability by several different techniques, such as delayed release of the active drug, fixed combinations of two different molecules, or incorporating ingredients into the formulation vehicle that improve epidermal barrier function and offset the irritating effects of the active drugs.

    The aim of this study was to investigate the ocular surface disorders and tear function changes in patients with nodulo-cystic acne. Eighty-seven patients with nodulo-cystic acne vulgaris and 50 healthy subjects were included in the study. All subjects underwent full ocular examinations. Subjective ocular complaints were recorded. Corneal staining with fluorescein, tear film break-up time (BUT), and Schirmer test were applied. Abnormal tear film BUT and abnormal Schirmer scores were significantly more common in the acne group than in the control group. The tear film BUT was abnormal in 18 (20.7%) cases in the patient group and in 2 (4%) subjects in the control group (p=0.007). The mean Schirmer score was abnormal in 7 (8%) and decreased in 18 (20.7%) acne patients, and it was decreased in only 3 (6%) control subjects (p=0.005). Corneal punctuate epithelial erosions were detected in 3 (3.4%) acne patients, but not any of the control subjects. However, the difference between the groups was not statistically significant (p=0.184). Subjective ocular complaints were present in 28 cases (32.2%) in the patient group. Five (10%) subjects in the control group had such complaints (p=0.003). Tear function tests are also significantly altered in patients with nodulo-cystic acne. Our data suggest that severe acne patients should be referred to an ophthalmologist.

    2011-03-15

    Acne vulgaris continues to be a challenge to dermatologists and primary care physicians alike. The available treatments reflect the complex and multifactorial contributors to acne pathogenesis, with topical retinoids as first-line therapy for mild acne, topical retinoids in combination with anti-microbials for moderate acne, and isotretinoin for severe nodular acne. Unfortunately, these conventional therapies may not be effective against refractory acne, can lead to antibiotic resistance, and is associated with adverse effects. With the rise of new technologies and in-office procedures, light and laser therapy, photodynamic therapy, chemical peels, and comedo extraction are growing in popularity as adjunctive treatments and may offer alternatives to those who desire better efficacy, quicker onset of action, improved safety profile, reduced risk of antibiotic resistance, and non-systemic administration. Whereas adjunctive therapies are generally well-tolerated, the number of randomized controlled trials are few and limited by small sample sizes. Furthermore, results demonstrating efficacy of certain light therapies are mixed and studies involving photodynamic therapy and chemical peels have yet to standardize and optimize application, formulation, and exposure times. Nevertheless, adjunctive therapies, particularly blue light and photodynamic therapy, show promise as these treatments also target factors of acne pathogenesis and may potentially complement current conventional therapy.

    Infantile acne is a rare and poorly understood disorder. The objective of this study was to improve our knowledge about the epidemiology and clinical course of infantile acne, and evaluate approaches to treatment. This two-center retrospective study covered the period between 1985 and 2007. Inclusion criteria were: (i) age less than 24 months when lesions appeared; (ii) presence of both inflammatory and noninflammatory lesions; (iii) persistence of lesions for at least 2 months. The data were drawn from clinical and photographic records, followed by administration of a telephone questionnaire to parents. It was proposed that each case be reviewed on the basis of the child's appearance and score on an acne scar clinical grading scale. Sixteen children were included. Nine had a family history of severe adolescent acne. The average duration of disease was 22 months. Two patients had been effectively treated with oral isotretinoin. More than half of the patients exhibited scars. We re-examined five children (average acne scar clinical grading scale score = 12/540). On the basis of the frequency of scarring, and the severity and average duration of lesions, the use of oral retinoids in severe infantile acne warrants evaluation.

  18. Differential diagnosis of facial acne on black skin.

    PubMed

    Poli, Florence

    2012-11-01

    The diagnosis of acne is usually easy, but there are some pitfalls to be avoided. 'Keloid acne of the neck' and beard folliculitis are not acnes in the usual sense: both are inflammatory and fibrous reactions of the hair follicles and frizzy hair; no retentional lesions, blackheads and microcysts--are visible. Gram negative folliculitis classically occurs in acneic male subjects who have undergone extensive treatment with general antibiotics or local antiseptics, but 'de novo' cases do exist. On black skin, this condition is not exceptional, it occurs in both sexes and usually takes the nodular form. The diagnosis should be considered if there is any aggravation of acne which is resistant to classic treatment, with painful nodules on the cheeks. Treatment is based on appropriate antibiotherapy for several weeks and possibly, in a second phase, on Isotretinoin. Pityrosporum folliculitis occurs mainly on the trunk. More frequent in men than in women, it is chiefly observed in subjects living in a hot, humid climate. Demodicidosis is manifested by outbreaks of papular or papulopustular lesions of the face. On black skin the principal differential diagnosis is acne. The presence of numerous parasites is necessary for diagnosis. Clinically speaking, an important sign is when the eyelids are affected. Ivermectin is effective. Acneiform dermatitis may be induced by depigmenting preparations containing powerful dermocorticoids. It is therefore important, in cases of very inflammatory acne, to look for the other clinical signs of voluntary depigmentation. In countries where it is endemic, lepromatous leprosy should be considered. Other common dermatitis may simulate acne or else be associated with it, such as eruptive hidradenoma or molluscum contagiosum. Analysis of the different elementary lesions and the absence of retentional lesions generally enable a diagnosis to be established.

    Acne is a common skin condition in adolescents. It is not uncommon in childhood and it persists into adulthood. A broad range of acne treatments are available and have been shown to be safe and effective in adolescents and adults. However, there is limited literature regarding acne treatment in childhood and its available therapeutic options. It seems reasonable to extrapolate findings of the various studies reported on treatment of acne in the adolescent and adult age group, with the exclusion of the use of tetracycline derivatives. As clinicians, we must be more familiar with the clinical presentation of acne and available treatment options in our younger patients. Early recognition of acne with prompt and appropriate initiation of therapy in childhood will help prevent severe scarring in children.

    Background Acne is a prominent skin condition affecting >80% of teenagers and young adults and ~650 million people globally. Isotretinoin, a vitamin A derivative, is currently the standard of care for treatment. However, it has a well-established teratogenic activity, a reason for the development of novel and low-risk treatment options for acne. Objective To investigate the effectiveness of Zolav®, a novel antibiotic as a treatment for acne vulgaris. Materials and methods Minimum inhibitory concentration of Zolav® against Propionibacterium acnes was determined by following a standard protocol using Mueller-Hinton broth and serial dilutions in a 96-well plate. Cytotoxicity effects on human umbilical vein endothelial cells and lung cells in the presence of Zolav® were investigated by determining the growth inhibition (GI50) concentration, total growth inhibition concentration, and the lethal concentration of 50% (LC50). The tryptophan auxotrophic mutant of Escherichia coli strain, WP2 uvrA (ATCC 49979), was used for the AMES assay with the addition of Zolav® tested for its ability to reverse the mutation and induce bacterial growth. The in vivo effectiveness of Zolav® was tested in a P. acnes mouse intradermal model where the skin at the infection site was removed, homogenized, and subjected to colony-forming unit (CFU) counts. Results Susceptibility testing of Zolav® against P. acnes showed a minimum inhibitory concentration of 2 µg/mL against three strains with no cytotoxicity and no mutagenicity observed at the highest concentrations tested, 30 µM and 1,500 µg/plate, respectively. The use of Zolav® at a concentration of 50 µg/mL (q8h) elicited a two-log difference in CFU/g between the treatment group and the control. Conclusion This study demonstrates the potential of Zolav® as a novel treatment for acne vulgaris. PMID:27042015

    Acne conglobata (AC) is a chronic, severe, inflammatory variant of acne characterized by development of cystic nodules, abscesses and sinus tracts. AC may prove resistant to conventional acne therapy. The off-label use of adalimumab for the treatment of AC has been reported recently. We present a 26-year-old man with AC resistant to conventional treatment, who was treated with 40 mg adalimumab every other week, with significant clinical improvement. We review the evidence for the use of tumour necrosis factor antagonists in AC and related conditions. This case provides further evidence supporting the role of adalimumab in the treatment of AC.

    Chlorophyllin (CHL), a chlorophyll-derivative, exhibits several beneficial properties, including antibacterial, antioxidant, and anticancer activities. However, its antibacterial and anti-inflammatory activities against Propionibacterium acnes have not been described. The antibacterial activity of this compound was evaluated in vitro using the broth microdilution method. CHL had an inhibitory effect on the growth of P. acnes (MIC = 100 μM). In a real-time reverse transcription-polymerase chain reaction and an enzyme-linked immunosorbent assay, CHL significantly decreased interleukin-8 (IL-8) and monocyte chemoattractant protein-1 (MCP-1) production in a dose-dependent manner, decreasing both mRNA and protein levels for these chemokines in THP-1 cells indicating the anti-inflammatory effects of it. To investigate the molecular mechanisms underlying the anti-inflammatory properties of CHL in THP-1 cells stimulated by P. acnes, we used western blotting to analyze the effect of CHL on activation of the nuclear factor (NF)-κB. CHL inhibited P. acnes-induced IL-8 and MCP-1 production via blockade of NF-κB activation in THP-1 cells. Therefore, based on these results, we suggest that CHL is a useful agent to control the growth of P. acnes involved in acne inflammation and prevent acne.

Film-forming solution bases and film-forming solutions containing AM were prepared by using Eudragit RL PO or Klucel LF or combinations of them as film-forming polymers. Rheological properties, pH values of the solutions, and mechanical properties of the dry films were investigated. An optimized formulation was selected and evaluated for the film surface, in vitro AM release, an anti-P. acnes activity, and potential for being a skin irritant. It was found that mechanical properties of the dry films were affected by total polymer contents, ratios of Klucel LF/Eudragit RL PO, AM, and contents of triethyl citrate. The film-forming solutions containing AM had pH values around 7.0. Their flow curves exhibited Newtonian flow behaviors. The optimized formulation provided films possessing smooth and nonporous surfaces. These films showed greater anti-P. acnes activity than their base films without toxicity to skin fibroblasts. Furthermore, AM released from the film matrix obeyed Higuchi's equation. In conclusion, the film-forming solutions containing AM had potential for treatment of acne vulgaris caused by P. acnes. However, further in vivo study is necessary to determine their efficacy and safety for using in patients suffering from acne vulgaris.

    ABSTRACT Propionibacterium acnes is an important skin commensal, but it is also considered a pathogenic factor in several diseases including acne vulgaris, the most common skin disease. While previous studies have revealed P. acnes strain-level differences in health and disease associations, the underlying molecular mechanisms remain unknown. Recently, we demonstrated that vitamin B12 supplementation increases P. acnes production of porphyrins, a group of proinflammatory metabolites important in acne development (D. Kang, B. Shi, M. C. Erfe, N. Craft, and H. Li, Sci. Transl. Med. 7:293ra103, 2015, doi:10.1126/scitranslmed.aab2009). In this study, we compared the porphyrin production and regulation of multiple P. acnes strains. We revealed that acne-associated type IA-2 strains inherently produced significantly higher levels of porphyrins, which were further enhanced by vitamin B12 supplementation. On the other hand, health-associated type II strains produced low levels of porphyrins and did not respond to vitamin B12. Using a small-molecule substrate and inhibitor, we demonstrated that porphyrin biosynthesis was modulated at the metabolic level. We identified a repressor gene (deoR) of porphyrin biosynthesis that was carried in all health-associated type II strains, but not in acne-associated type IA-2 strains. The expression of deoR suggests additional regulation of porphyrin production at the transcriptional level in health-associated strains. Our findings provide one potential molecular mechanism for the different contributions of P. acnes strains to skin health and disease and support the role of vitamin B12 in acne pathogenesis. Our study emphasizes the importance of understanding the role of the commensal microbial community in health and disease at the strain level and suggests potential utility of health-associated P. acnes strains in acne treatment.

  6. Chemical peels in active acne and acne scars.

    PubMed

    Kontochristopoulos, Georgios; Platsidaki, Eftychia

    Chemical peeling is a widely used procedure in the management of acne and acne scars. It causes controlled destruction of a part of or the entire epidermis, with or without the dermis, leading to exfoliation and removal of superficial lesions, followed by regeneration of new epidermal and dermal tissues. The most frequently used peeling agents are salicylic acid, glycolic acid, pyruvic acid, lactic acid, mandelic acid, Jessner solution, trichloroacetic acid, and phenol. The appropriate peel is chosen based on the patient's skin type, acne activity, and type of acne scars. Combination peels minimize side effects. In acne scars, chemical peels may be combined with other procedures to achieve better clinical results. A series of chemical peels can lead to significant improvement over a short period, leading to patient satisfaction and maintenance of clinical results. © 2016 Elsevier Inc. All rights reserved.

    Many drugs have been shown to induce pemphigus, including thiol and nonthiol drugs. We present a case of pemphigus vulgaris where a nonsteroidal anti-inflammatory medication, diclofenac in suppositories and topical gel preparations, is suspected of having triggered the disease. The temporal relationship between drug and outbreak of disease together with the positive migration inhibition factor test to diclofenac point to the possible involvement of this drug in triggering pemphigus vulgaris.

    We examined the possible correlation between biotypes of Propionibacterium acnes, lipase activity, and rash degree in acne patients. Among 5 P. acnes biotypes, P. acnes biotype 3 (B3) was the most common, followed by P. acnes biotypes 1, 2 and 4; P. acnes biotype 5 was not found. P. acnes B3 was isolated from more severe skin rashes than those of the other biotypes. Production of propionic acid (PA) and butyric acid (BA) by P. acnes B3 was higher than those by the other P. acnes biotypes. As the rash degree in acne patients was more severe, the production of PA and BA elevated. Although only a few P. acnes strains were examined in the present study, P. acnes B3 had the highest lipase activity and might have the greatest influence on skin rash in acne patients.

    Environmental pollutants can result in a variant of acne called 'chloracne'. Chloracne is caused by systemic exposure to certain halogenated aromatic hydrocarbons 'chloracnegens', and is considered to be one of the most sensitive indicators of systemic poisoning by these compounds. Dioxin is the most potent environmental chloracnegen. Most cases of chloracne have resulted from occupational and non-occupational exposures, non-occupational chloracne mainly resulted from contaminated industrial wastes and contaminated food products. Non-inflammatory comedones and straw-colored cysts are the primary clinical manifestation of chloracne. Increasing of cysts in number is a signal of aggravation of chloracne. Generalized lesions can appear on the face, neck, trunk, exterimities, genitalia, axillary and other areas. Course of chloracne is chronic. Severity of chloracne is related to dosage of exposed chloracnegens, chloracnegenic potency and individual susceptibility. Histopathology of chloracne is characterized mainly by hyperplasia of epidermal cell, while follicular and sebaceous gland are taken placed by keratinized epidermal cell. The pathogenesis of chloracne maybe related to the imbalance of epidermal stem cell. Chloracne appears to be resistant to all tested forms of treatment. The only way to control chloracne is to prevent exposure to chloracnegens.

    Acne and body hair are both cutaneous responses to androgenic stimulation. They are normal events in adolescent girls. There is considerable variation in the evolution of the two conditions. The sebaceous gland is exquisitely sensitive to androgens, and acne appears with the onset of puberty, peaks in prevalence in the teenage years and gradually improves thereafter. Hair growth on the face, trunk and limbs develops more slowly and generally peaks in the 20s. Indications for endocrine investigation include very severe acne, onset of acne and hirsuties in the very early stage of puberty (Tanner stage 3) and systemic virilism. Treatment for acne and hirsuties can be either topical or systemic. The choice of therapy is based on the severity of the disease rather than the results of endocrine investigation. Further, since PCO is related to impaired glucose tolerance, advice relating to lifestyle changes should be offered to prevent the development of diabetes.

    Acne is a common skin disorder of the pilosebaceous unit. In addition to genetic, hormonal and environmental factors, abnormal colonization by Propionibacterium acnes has been implicated in the occurrence of acne via the induction of inflammatory mediators. To gain more insight into the role that sebocytes play in the innate immune response of the skin, particularly in acne, we compared the antimicrobial peptide and proinflammatory cytokine/chemokine expression at mRNA and protein levels, as well as the viability and differentiation of SZ95 sebocytes in response to co-culture with representative isolates of P. acnes type IA and type IB as well as Escherichia coli-derived lipopolysaccharide (LPS). We found that, in vitro, P. acnes type IA and IB isolates and LPS induced human beta-defensin-2 and proinflammatory cytokine/chemokine expression, and influenced sebocyte viability and differentiation. Our results provide evidence that sebocytes are capable of producing proinflammatory cytokines/chemokines and antimicrobial peptides, which may have a role in acne pathogenesis. Furthermore, since P. acnes types IA and IB differentially affect both the differentiation and viability of sebocytes, our data demonstrate that different strains of P. acnes vary in their capacity to stimulate an inflammatory response within the pilosebaceous follicle.

    Although antibiotics are a common treatment for acne, the difficulties inherent to effective antimicrobial penetration in sebum and selective antimicrobial action in skin are compounded by increasing resistance of Propionibacterium acnes clinical isolates. To address these problems, we engineered Pentobra, a peptide-aminoglycoside molecule which has multiple mechanisms of antibacterial action, and investigated whether it can be a potential candidate for the treatment of acne. Pentobra combines the potent ribosomal activity of aminoglycosides with the bacteria-selective membrane-permeabilizing abilities of antimicrobial peptides (AMPs). Pentobra demonstrated potent and selective killing of P. acnes, but not against human skin cells in vitro. In direct comparison, Pentobra demonstrated bactericidal activity and drastically outperformed free tobramycin (by 5–7 logs) against multiple P. acnes clinical strains. Moreover, EM studies showed that Pentobra had robust membrane activity, as treatment with Pentobra killed P. acnes cells and caused leakage of intracellular contents. Pentobra may also have potential anti-inflammatory effects as demonstrated by suppression of some P. acnes-induced chemokines. Importantly, the killing activity was maintained in sebaceous environments as Pentobra was bactericidal against clinical isolates in comedones extracts isolated from human donors. Our work demonstrates that equipping aminoglycosides with selective membrane activity is a viable approach for developing antibiotics against P. acnes that are effective in cutaneous environments.

    Atopic dermatitis (AD) and acne vulgaris are among the most-prevalent skin diseases in children. Both have been well documented in the literature to have significant negative effects on quality of life. Herein, we discuss the results of a comprehensive literature review aimed at assessing the impact of acne and AD on self-esteem and identity. We highlight clinical tools for their assessment and offer coping strategies for patients and families. Multiple factors including relationships with parents and classmates, sports participation, and the sex of the patient contribute to the development of self-esteem and identity in individuals with AD and acne. Atopic dermatitis was found to have significant behavioral effects on children, ultimately resulting in a lack of opportunity to develop proper coping. AD had a more-prominent role in identity formation and gender roles in girls. Acne vulgaris was found to have a more direct effect on self-esteem, self-confidence and identity, especially in girls. The Cutaneous Body Image Scale is reviewed and offered as an easy and reliable tool to evaluate a patient's mental perception of the appearance of their skin. Coping strategies that may be offered to patients and families include empowerment and cognitive adaptation.

    Isotretinoin (13-cis retinoic acid) is an effective treatment for severe cystic or recalcitrant acne vulgaris; however, concerns have been raised regarding its potential association with depression and suicidal behavior. We sought to explore the proposed relationship between isotretinoin use and the risk of depression and attempted and completed suicide in patients with acne vulgaris by performing a systematic literature search for studies reporting primary data on depression and suicidal behavior in patients treated with isotretinoin for acne vulgaris. Nine studies met the qualifying criteria for our analysis. Rates of depression among isotretinoin users ranged from 1% to 11% across studies, with similar rates in oral antibiotic control groups. Overall, studies comparing depression before and after treatment did not show a statistically significant increase in depression diagnoses or depressive symptoms. Some, in fact, demonstrated a trend toward fewer or less severe depressive symptoms after isotretinoin therapy. This decrease was particularly evident in patients with pretreatment scores in the moderate or clinical depression range. No correlation between isotretinoin use and suicidal behavior was reported, although only one retrospective study presented data on this topic. Although the current literature does not support a causative association between isotretinoin use and depression, there are important limitations to many of the studies. The available data on suicidal behavior during isotretinoin treatment are insufficient to establish a meaningful causative association.

    Background Vitamin D plays an important role in the immune system, and its deficiency has been implicated in various skin diseases, including atopic dermatitis and psoriasis. Acne is a common inflammatory skin disease; however, the association with vitamin D remains unclear. Objectives We evaluated vitamin D levels in patients with acne to determine the effect of vitamin D supplementation. Methods This study included 80 patients with acne and 80 healthy controls. Serum 25-hydroxyvitamin D (25(OH)D) levels were measured, and demographic data were collected. Vitamin D-deficient patients were treated with oral cholecalciferol at 1000 IU/day for 2 months. Results Deficiency in 25(OH)D was detected in 48.8% of patients with acne, but in only 22.5% of the healthy controls. The level of 25(OH)D was inversely associated with the severity of acne, and there was a significant negative correlation with inflammatory lesions. In a subsequent trial, improvement in inflammatory lesions was noted after supplementation with vitamin D in 39 acne patients with 25(OH)D deficiency. Limitations Limitations of the study include the small number of patients in the supplementation study and the natural fluctuation of acne. Conclusions Vitamin D deficiency was more frequent in patients with acne, and serum 25(OH)D levels were inversely correlated with acne severity, especially in patients with inflammatory lesions.

    Acne vulgaris is a nearly universal cutaneous disease characterized by multifactorial pathogenic processes. Because current acne medications have various side effects, investigating new pharmacologically active molecules is important for treating acne. As natural products generally provide various classes of relatively safe compounds with medicinal potentials, we performed activity-guided purification after a series of screenings from the extracts of five medicinal plants to explore alternative acne medications. Lupeol, a pentacyclic triterpene, from the hexane extract of Solanum melongena L. (SM) was identified after instrumental analysis. Lupeol targeted most of the major pathogenic features of acne with desired physicochemical traits. It strongly suppressed lipogenesis by modulating the IGF-1R/phosphatidylinositide 3 kinase (PI3K)/Akt/sterol response element-binding protein-1 (SREBP-1) signaling pathway in SEB-1 sebocytes, and reduced inflammation by suppressing the NF-κB pathway in SEB-1 sebocytes and HaCaT keratinocytes. Lupeol exhibited a marginal effect on cell viability and may have modulated dyskeratosis of the epidermis. Subsequently, histopathological analysis of human patients' acne tissues after applying lupeol for 4 weeks demonstrated that lupeol markedly attenuated the levels of both the number of infiltrated cells and major pathogenic proteins examined in vitro around comedones or sebaceous glands, providing solid evidence for suggested therapeutic mechanisms. These results demonstrate the clinical feasibility of applying lupeol for the treatment of acne.

    Eucalyptus bridgesiana, Cymbopogon martinii, Thymus vulgaris, Lindernia anagallis, and Pelargonium fragrans are five species of herbs used in Asia. Their essential oils were analyzed by GC-MS, and a total of 36 components were detected. The results of our study indicated that, except for the essential oil of P. fragrans, all of the essential oils demonstrated obvious antimicrobial activity against a broad range of microorganisms. The C. martinii essential oil, which is rich in geraniol, was the most effective antimicrobial additive. All of the essential oils demonstrated antioxidant activities on 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay, β-carotene/linoleic acid assay, and nitric oxide radical scavenging assay. Furthermore, the T. vulgaris essential oil, which possesses plentiful thymol, exhibited the highest antioxidant activity. For P. acnes-induced secretion of pro-inflammatory cytokines, the essential oils of P. aeruginosa, C. martinii, and T. vulgaris reduced the TNF-α, IL-1β, and IL-8 secretion levels of THP-1 cells.

    Propionibacterium. acnes is a Gram positive, microaerophilic bacterium which takes a part in the pathogenesis of inflammatory acne. P. acnes is capable to produce high amounts endogenic porphyrins with no need of any trigger molecules. Light in the violet-blue range (407-420 nm) has been shown to exhibit a phototoxic effect on Propionibacterium acnes when irradiated in vitro. The purpose of our study was to test the clinical effects of a high intensity narrowband blue light source on papulo pustular acne. A total of 35 patients in 3 centers were treated twice a week with a high intensity metal halide lamp illuminating the entire face (20x20 cm2) or the back with visible light in the 407-420 nm range at an intensity of 90 mW/cm2 (CureLight Ltd.) for a total of 4 weeks. UV is totally cut off. In each treatment the patient was exposed to light for 8-15 minutes. After 8 treatments, 80% of the patients with mild to moderate papulo-pustular acne showed significant improvement at reducing the numbers of non- inflammatory, inflammatory and total facial lesions. Inflammatory lesion count decrease by a mean of 68%. No side effects to the treatment were noticed. In conclusion, full face or back illumination with the high intensity pure blue light we used exhibits a rapid significant decrease in acne lesions counts in 8 biweekly treatments.

    Acne is the most common skin disease, with a relative prevalence of 85%-100% among young individuals. It affects the cosmetic appearance of the patients provoking severe distress. A number of different topical treatments have been used for the treatment of acne. In this study, we investigated the efficacy and safety of the topical treatment with 5% benzoyl peroxide and 3% erythromycin gel in patients with papulopustular acne. One hundred and ninety-one patients with inflammatory acne completed the study. The patients included 54 males and 137 females, mean age 22.3 ± 8.1 years. Topical gel was applied on the face once daily for 3 months. The mean number of non-inflammatory and inflammatory lesions after 3 months of therapy decreased significantly with respect to baseline, with a mean percentage reduction of the non-inflammatory and inflammatory lesions by 42.2% and 57.5%, respectively. In conclusion, topical 5% benzoyl peroxide and erythromycin 3% as monotherapy is efficient for the treatment of papulopustular acne.

    Chronic inflammation in the prostate, seen as infiltration of inflammatory cells into the prostate gland in histological samples, affects approximately half the male population without indication of prostate disease, and is almost ubiquitous in patients diagnosed with benign prostate hyperplasia and cancer. Several studies have demonstrated the gram-positive bacterium Propionibacterium acnes to be frequently present in prostate tissue from men suffering from prostate disease. P. acnes has been shown to be associated with histological inflammation in human prostatectomy specimens, and also to induce strong inflammatory response in prostate-derived tissue culture models. The present paper describes a rat model for assessment of the pathogenic potential of P. acnes in prostate. Prostate glands of Sprague Dawley rats (n = 98) were exposed via an abdominal incision and live P. acnes or, in control rats, saline were injected into the ventral and dorso-lateral lobes. Rats were sacrificed 5 days, 3 weeks, 3 months and 6 months post infection, and prostate tissue was analyzed for bacterial content and histological inflammation. Rat sera were assessed for levels of CRP and anti-P. acnes IgG. Live P. acnes could be recovered from the dorso-lateral lobes up to 3 months post infection, while the ventral lobes were cleared from bacteria at that time. In samples up to 3 months post infection, the dorso-lateral lobes exhibited intense focal inflammation. CRP and IgG levels were elevated throughout the span of the experiment, and reached maximum levels 3 weeks and 3 months post infection, respectively. We show that P. acnes have the potential to cause chronic infection in previously healthy prostate, and that the infection has potential to cause chronic histological inflammation in the infected tissue. The high prevalence of P. acnes in human prostate tissue calls for resolution of pathogenic details. The present rat model suggests that complications such as chronic

    Acne inversa (AI, hidradenitis suppurativa, Velpeau’s disease, Verneuil’s disease) is a severe, chronic inflammatory dermatosis of unknown etiology, detected on the basis of clinical symptoms more frequently in women than in men. Purulent lesions in the form of nodules and inflammatory tumors, fistulas and scars are present in the areas with hair follicles and apocrine glands, most commonly on the armpits, groin, around the anus and pubic region. Acne inversa can lead to physical and mental disorders. Unfortunately, it is often misdiagnosed and ineffectively treated. The paper presents a case of a 46-year-old patient who was successfully treated surgically for AI around the anus and buttocks by excision of the changes and closure of the wound with local flaps and split-thickness skin grafts, taken with dermatome from the rear surface of the thighs. Surgical treatment is the method of choice in the treatment of severe AI. PMID:24278084

    We have recently reported that patients with severe nodular cystic acne have much lower levels of HDL-cholesterol, apolipoprotein A and hepatic lipoprotein lipase than healthy controls or subjects with acne vulgaris. Since isotretinoin is very effective in the treatment of the nodular cystic acne but has been shown to increase blood lipid levels, we decided to compare its clinical effectiveness and its effects on lipid metabolism with those of minocycline in patients with nodular cystic acne. After 20 weeks, the number and mean diameter of the cysts were definitely decreased in both groups, but the improvement was more striking in the isotretinoin-treated group. At the end of the treatment, the HDL-C and hepatic lipoprotein lipase levels in this group were increased toward normal, but not in the minocycline-treated group. Our study showed a significant remission in the acne of patients treated with isotretinoin but not in that of the minocycline-treated patients. Furthermore isotretinoin can also correct the altered lipid metabolism in these patients.

    Propionibacterium acnes is implicated in the pathogenesis of acne vulgaris, which impacts >85% of teenagers. Novel therapies are in high demand and an ethnopharmacological approach to discovering new plant sources of anti-acne therapeutics could contribute to filling this void in effective therapies. The aims of our study were two-fold: (1) To determine if species identified in ethnopharmacological field studies as having traditional uses for skin and soft tissue infection (SSTI) exhibit significantly more activity against P. acnes than species with no such reported use; and (2) Chemically characterize active extracts and assess their suitability for future investigation. Extracts of Italian medicinal (for acne and other skin infection) and randomly collected plants and fungi were screened for growth-inhibitory and anti-biofilm activity in P. acnes using broth microdilution methods. Bioactive extracts were chemically characterized by HPLC and examined for cytotoxicity against human keratinocytes (HaCaTs). Following evaluation of 157 extracts from 10 fungi and 58 plants, we identified crude extracts from seven species exhibiting growth inhibitory activity (MICs 64–256 μg mL−1). All active extracts were examined for cytotoxicity against HaCaTs; extracts from one fungal and one plant species were toxic (IC50 256 μg mL−1). HPLC analysis with chemical standards revealed many of these extracts contained chlorogenic acid, p-coumaric acid, ellagic acid, gallic acid, and tannic acid. In conclusion, species used in traditional medicine for the skin exhibited significantly greater (p < 0.05) growth inhibitory and biofilm eradication activity than random species, supporting the validity of an ethnobotanical approach to identifying new therapeutics. The anti-acne activity of three extracts is reported for the first time: Vitis vinifera leaves, Asphodelus microcarpus leaves, and Vicia sativa aerial parts. PMID:27891094

    Background Acne vulgaris is a pilosebaceous follicle disorder affecting over 85% of adolescents to some degree. It frequently causes psychological distress that may persist into adulthood due to scarring. Little information about post-acne scarring epidemiology is available. Objectives To describe prevalence, distribution patterns and associated factors of acne scarring in young males, drawing on a representative population sample from a southern Brazilian city. Methods A cross-sectional study was undertaken during presentation for military service, which is compulsory for all 18-year-old males. A questionnaire was applied, covering topics like diet, smoking habits, ethnicity, family structure, socio-economic level, as well as specific questions about active acne and resulting scars. Dermatologists conducted the clinical examination. Results A total of 2,201 male adolescents were interviewed and examined. The overall prevalence of acne scarring was 22%. The malar region was the most frequently involved, present in 80% of affected individuals, followed by the frontal region (31.5%), back (17%), anterior chest (8.2%) and mentonian region (6.4%). Correlation between the intensity of clinical acne and the presence of scars was found, but no association was observed with educational level, smoking, ethnicity, obesity or socio-economic status. Conclusions There is a high prevalence of acne scars among this population. This is the first study to ascertain a correlation between acne scarring and factors such as socio-economic status and educational level. The direct relation between acne severity and scarring indicates that prompt and effective treatment is the best way to reduce scarring. PMID:27438194

    The identification of Propionibacterium acnes in cultures of bone and joint samples is always difficult to interpret because of the ubiquity of this microorganism. The aim of this study was to propose a diagnostic strategy to distinguish infections from contaminations. This was a retrospective analysis of all patient charts of those patients with >or=1 deep samples culture-positive for P. acnes. Every criterion was tested for sensitivity, specificity, and positive likelihood ratio, and then the diagnostic probability of combinations of criteria was calculated. Among 65 patients, 52 (80%) were considered truly infected with P. acnes, a diagnosis based on a multidisciplinary process. The most valuable diagnostic criteria were: >or=2 positive deep samples, peri-operative findings (necrosis, hardware loosening, etc.), and >or=2 surgical procedures. However, no single criterion was sufficient to ascertain the diagnosis. The following combinations of criteria had a diagnostic probability of >90%: >or=2 positive cultures + 1 criterion among: peri-operative findings, local signs of infection, >or=2 previous operations, orthopaedic devices; 1 positive culture + 3 criteria among: peri-operative findings, local signs of infection, >or=2 previous surgical operations, orthopaedic devices, inflammatory syndrome. The diagnosis of P. acnes osteomyelitis was greatly improved by combining different criteria, allowing differentiation between infection and contamination.

    Background Laser/light-based devices may provide an alternative to conventional acne therapeutics in some patients with nonresponsive acne. Objective We investigated the efficacy of red or infrared light-emitting diode (LED) devices in a mouse model of Propionibacterium acnes-induced inflammation through clinical examination and histopathological and immunohistochemical studies. Methods A human-derived Propionibacterium acnes suspension (109 colony-forming units /µl) was injected into the back of an HR-1 mouse. Then, a 28.9 J/cm2 650-nm red LED or 9.3 J/cm2 830-nm infrared LED was applied to the mouse with P. acnes-induced inflammation once daily for 2 weeks. Two weeks after treatment, histological findings with hematoxylin and eosin staining and expression levels of inflammatory biomarkers (integrin α6, neutrophils, interleukin [IL]-1β, and matrix metalloproteinase [MMP]-2/9) were evaluated in tissue specimens using immunohistochemical staining. Results Mice treated with red and infrared LED showed clinical improvement in inflammatory nodules compared to mice in the control group. Red LED was much more effective than infrared LED. Epidermal hyperplasia, comedone-like cysts, and integrin α6 expression improved to a similar extent in the red and infrared LED treatment groups and control group. Neutrophil, IL-1β, MMP-2, and MMP-9 expression after treatment with red and infrared LED decreased considerably compared to expression in the control group. Conclusion In a mouse model of P. acnes-induced inflammatory nodules, red and infrared LED devices may be an alternative to conventional acne therapies. In addition, a mouse model of P. acnes-induced inflammatory nodules is helpful for laboratory research of acne. PMID:27081265

    Magrey, Marina; Khan, Muhammad A

    2009-10-01

    In 1987, synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome was proposed as an umbrella term for a group of diseases with similar musculoskeletal manifestations, in particular hyperostosis of anterior chest wall, synovitis, and multifocal aseptic osteomyelitis, observed in association with dermatologic conditions such as palmoplantar pustulosis, severe acne, and hidradenitis suppurativa. Despite recent advances in our understanding of the epidemiologic, pathophysiologic, and immunogenetic mechanisms involved in SAPHO syndrome, etiopathogenesis remains poorly understood. Propionibacterium acnes, the microorganism associated with acne, has been recovered on bone biopsy in some patients, but the possible pathogenetic role of an infectious agent in a genetically predisposed individual, resulting in exaggerated inflammatory response as "reactive osteitis," is a largely unproven hypothesis. The newly available whole-body MRI will assist early diagnosis by detecting multifocal osteitis lesions, some of them asymptomatic, in axial (anterior chest wall, spine, and jaws) and nonaxial sites. Moreover, outcomes are vastly improved by treatment with bisphosphonates and tumor necrosis factor-alpha antagonists.

    Introdução: A acne, apesar de caraterística no adolescente, afeta frequentemente o adulto. Em Portugal, não são conhecidos estudos sobre a prevalência da acne no adulto, nomeadamente observada nos grandes centros populacionais. Os objetivos deste estudo foram estimar a prevalência da acne nos utentes dos serviços de cuidados de saúde primários, as suas características, incluindo fatores de risco para início e/ou agravamento, além de coletar informação relacionada com a automedicação e/ou tratamento prescrito. Material e Métodos: Aplicação de questionário e exame físico a amostra composta por adultos entre os 20 - 60 anos de idade que visitaram, em dias aleatórios, cinco centros de saúde da área do Grande Porto. Resultados: Dos 1 055 adultos avaliados, a prevalência estimada de acne foi de 61,5%. Apenas 36,8% dos portadores estavam cientes da sua condição e somente 25% afirmou ter procurado tratamento. Mais de metade dos fumadores (62,3%) apresentavam acne. A zona mais afetada foi a região malar, diferindo da forma adolescente da doença. Discussão: A prevalência encontrada de acne foi mais elevada do que em outros estudos. A acne aparentou estar relacionada com a ingestão calórica aumentada, tabagismo, consumo de leite gordo ou meio gordo, hirsutismo, alopécia e seborreia. Conclusão: No contexto dos cuidados de saúde primários, mais de metade dos adultos eram portadores de acne. Estes números demonstram o quão importante pode ser a prevenção e intervenção pelos profissionais dos cuidados de saúde primários, tanto para a redução de eventuais factores de risco como para a intervenção terapêutica e consequências psicossociais relacionadas com a acne.

    The Gram-positive anaerobic bacterium Propionibacterium acnes is a prevalent member of the normal skin microbiota of human adults. In addition to its suspected role in acne vulgaris it is involved in a variety of opportunistic infections. Multi-locus sequence-typing (MLST) schemes identified distinct phylotypes associated with health and disease. Being based on 8 to 9 house-keeping genes these MLST schemes have a high discriminatory power, but their application is time- and cost-intensive. Here we describe a single-locus sequence typing (SLST) scheme for P. acnes. The target locus was identified with a genome mining approach that took advantage of the availability of representative genome sequences of all known phylotypes of P. acnes. We applied this SLST on a collection of 188 P. acnes strains and demonstrated a resolution comparable to that of existing MLST schemes. Phylogenetic analysis applied to the SLST locus resulted in clustering patterns identical to a reference tree based on core genome sequences. We further demonstrate that SLST can be applied to detect multiple phylotypes in complex microbial communities by a metagenomic pyrosequencing approach. The described SLST strategy may be applied to any bacterial species with a basically clonal population structure to achieve easy typing and mapping of multiple phylotypes in complex microbiotas. The P. acnes SLST database can be found at http://medbac.dk/slst/pacnes. PMID:25111794

    Acne, one of the most common skin disorders, is also a cardinal component of many systemic diseases or syndromes. Their association illustrates the nature of these diseases and is indicative of the pathogenesis of acne. Congenital adrenal hyperplasia (CAH) and seborrhoea-acne-hirsutism-androgenetic alopecia (SAHA) syndrome highlight the role of androgen steroids, while polycystic ovary (PCO) and hyperandrogenism-insulin resistance-acanthosis nigricans (HAIR-AN) syndromes indicate insulin resistance in acne. Apert syndrome with increased fibroblast growth factor receptor 2 (FGFR2) signalling results in follicular hyperkeratinization and sebaceous gland hypertrophy in acne. Synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) and pyogenic arthritis-pyoderma gangrenosum-acne (PAPA) syndromes highlight the attributes of inflammation to acne formation. Advances in the understanding of the manifestation and molecular mechanisms of these syndromes will help to clarify acne pathogenesis and develop novel therapeutic modalities.

    2012-01-01

    Chemical peeling is a widely used procedure in the management of acne and acne scars, but there are very few studies on Asian populations who are more prone to develop hyper pigmentation. This article aims to summarize and evaluate the existing studies on the role of chemical peels in the treatment of acne and acne scars among Asians. An online search was conducted to identify prospective studies published in English that evaluated the use of chemical peels in active acne and acne scars in Asian populations. There were six studies for acne and eight studies for acne scars that were identified using our search parameters. Most were single-centre, open label and with small sample sizes. Acne severity was not uniformly reported and the objective outcome measures of some studies were not explicitly reported as well. The general trend of the results of the studies support the safety and efficacy of chemical peels for acne and acne scars including those of darker skin types. The existing studies support the use of chemical peels in the treatment of acne and acne scars in Asians. Further clinical trials with better study design and more subjects are needed to further establish the role of chemical peels in Asian acne patients. PMID:23378705

    Acne is the most common skin disorder. In the majority of cases, acne is a disease that changes its skin distribution and severity over time; moreover, it can be a physically (scar development) and psychologically damaging condition that lasts for years. According to its clinical characteristics, it can be defined as a chronic disease according to the World Health Organization criteria. Acne is also a cardinal component of many systemic diseases or syndromes, such as congenital adrenal hyperplasia, seborrhea-acne-hirsutism-androgenetic alopecia syndrome, polycystic ovarian syndrome, hyperandrogenism-insulin resistance-acanthosis nigricans syndrome, Apert syndrome, synovitis-acne-pustulosis-hyperostosis-osteitis syndrome, and pyogenic arthritis-pyoderma gangrenosum-acne syndrome. Recent studies on the Ache hunter gatherers of Paraguay detected the lack of acne in association with markedly lower rates of obesity, diabetes mellitus, hyperlipidemia, and cardiovascular diseases, a finding that indicates either a nutritional or a genetic background of this impressive concomitance.

    A 27-year-old man presented with a 10-year history of scarring alopecia on the vertex of the scalp associated with follicular crusting and pustule formation, and a papular eruption on the posterior neck. Additionally, there was keratosis pilaris on the cheeks, eyebrows and thighs. Histology from the vertex showed scarring with a mixed perifollicular inflammatory infiltrate and foci of acute suppurative folliculitis. With clinical correlation, the diagnosis of keratosis follicularis spinulosa decalvans and concurrent acne keloidalis nuchae was made. The association of keratosis follicularis spinulosa decalvans with acne keloidalis nuchae has not previously been described. The patient responded to treatment with oral isotretinoin 20 mg (0.25 mg/kg) daily for 12 months.

    Objective: Acne vulgaris is a dynamic, complex condition that is notoriously difficult to evaluate. The authors set out to critically evaluate currently available measures of acne severity, particularly in terms of suitability for use in clinical trials. Design: A systematic review was conducted to identify methods used to measure acne severity, using MEDLINE, CINAHL, Scopus, and Wiley Online. Each method was critically reviewed and given a score out of 13 based on eight quality criteria under two broad groupings of psychometric testing and suitability for research and evaluation. Results: Twenty-four methods for assessing acne severity were identified. Four scales received a quality score of zero, and 11 scored ≤3. The highest rated scales achieved a total score of 6. Six scales reported strong inter-rater reliability (ICC>0.75), and four reported strong intra-rater reliability (ICC>0.75). The poor overall performance of most scales, largely characterized by the absence of reliability testing or evidence for independent assessment and validation indicates that generally, their application in clinical trials is not supported. Conclusion: This review and appraisal of instruments for measuring acne severity supports previously identified concerns regarding the quality of published measures. It highlights the need for a valid and reliable acne severity scale, especially for use in research and evaluation. The ideal scale would demonstrate adequate validation and reliability and be easily implemented for third-party analysis. The development of such a scale is critical to interpreting results of trials and facilitating the pooling of results for systematic reviews and meta-analyses. PMID:27672410

    We measured hormone levels in 59 women and 32 men with longstanding cystic acne resistant to conventional therapy. Affected women had higher serum levels of dehydroepiandrosterone sulfate, testosterone, and luteinizing hormone and lower levels of sex-hormone-binding globulin than controls. Affected men had higher levels of serum dehydroepiandrosterone sulfate and 17-hydroxyprogesterone and lower levels of sex-hormone-binding globulin than controls. To lower dehydroepiandrosterone sulfate, dexamethasone was given to men, and dexamethasone or an oral contraceptive pill, Demulen (or both), was given to women. Of the patients treated for six months, 97 per cent of the women and 81 per cent of the men had resolution or marked improvement in their acne. The dose of dexamethasone required to reduce dehydroepiandrosterone sulfate levels was low, rarely exceeding the equivalent of 20 mg of hydrocortisone per day. We conclude that most patients with therapeutically resistant cystic acne have androgen excess and that lowering elevated dehydroepiandrosterone sulfate results in improvement or remission of acne in most instances.

    Virulence enzymes and biofilm a play crucial role in the pathogenesis of Propionibacterium acnes, a major causative agent of acne vulgaris. In the present study, the effects of rhodomyrtone, a pure compound identified from Rhodomyrtus tomentosa (Aiton) Hassk. leaves extract against enzyme production and biofilm formation production by 5 clinical isolates and a reference strain were evaluated. The degree of hydrolysis by both lipase and protease enzymes significantly decreased upon treatment with the compound at 0.125-0.25 μg/mL (p < 0.05). Lipolytic zones significantly reduced in all isolates while decrease in proteolytic activities was found only in 50% of the isolates. Rhodomyrtone at 1/16MIC and 1/8MIC caused significant reduction in biofilm formation of the clinical isolates (p < 0.05). Percentage viability of P. acnes within mature biofilm upon treated with the compound at 4MIC and 8MIC ranged between 40% and 85%. Pronounced properties of rhodomyrtone suggest a path towards developing a novel anti-acne agent.

    This review examines the efficacy and safety of fractional CO2 lasers for the treatment of atrophic scarring secondary to acne vulgaris. We reviewed 20 papers published between 2008 and 2013 that conducted clinical studies using fractional CO2 lasers to treat atrophic scarring. We discuss the prevalence and pathogenesis of acne scarring, as well as the laser mechanism. The histologic findings are included to highlight the ability of these lasers to induce the collagen reorganization and formation that improves scar appearance. We considered the number of treatments and different laser settings to determine which methods achieve optimal outcomes. We noted unique treatment regimens that yielded superior results. An overview of adverse effects is included to identify the most common ones. We concluded that more studies need to be done using uniform treatment parameters and reporting in order to establish which fractional CO2 laser treatment approaches allow for the greatest scar improvement.

    The management of acne vulgaris is a long-term process that must be individualized to each patient. Relevant factors influencing treatment include the age and gender of the patient, the severity and extent of disease, the efficacy and tolerability of prior interventions, and the degree of compliance with recommended therapies. The follow-up phase of acne management requires a framework for approaching treatment modification that may include concepts such as up-titration, add-on, or switching of available agents to improve efficacy and tolerability. Whenever oral antibiotics are used, abrupt discontinuation in favor of topical maintenance therapy rather than gradual tapering is recommended. Strategies for assessing and optimizing medical adherence are reviewed.

    Various methods of photodynamic therapy (PDT) for acne have been introduced. However, comparative studies among them are still needed. We performed this study to compare the effect of methyl aminolevulinate (MAL) PDT for acne between red light and intense pulsed light (IPL). Twenty patients were enrolled in this eight-week, prospective, split-face study. We applied MAL cream over the whole face with a three-hour incubation time. Then patients were irradiated with 22 J/cm(2) of red light on one-half of the face and 8-10 J/cm(2) of IPL on the other half during each treatment session. We performed three treatment sessions at two-week intervals and followed-up patients until four weeks after the last session. Inflammatory and non-inflammatory acne lesions were reduced significantly on both sides. The red light side showed a better response than the IPL side after the first treatment. Serious adverse effects after treatment were not observed. MAL-PDT with red light and IPL are both an effective and safe modality in acne treatment. Red light showed a faster response time than IPL. After multiple sessions, both light sources demonstrated satisfactory results. We suggest that reducing the total dose of red light is desirable when performing MAL-PDT in Asian patients with acne compared with Caucasians.

    Staphylococcus aureus might amplify symptoms in chronic inflammatory skin diseases. This study evaluates skin and mucosal colonization with S. aureus in patients with psoriasis, acne and rosacea. A systematic literature search was conducted. Both odds ratios (OR) for colonization in patients versus controls and the prevalence of colonization in patients are reported. Fifteen articles about psoriasis and 13 about acne (12 having a control group) were included. No study in rosacea met our inclusion criteria. For psoriasis, one study out of three controlled studies showed increased skin colonization (OR 18.86; 95 % confidence interval [CI] 2.20-161.99). Three out of the five studies that reported on nasal colonization showed significant ORs varying from 1.73 (95 % CI 1.16-2.58) to 14.64 (95 % CI 2.82-75.95). For acne one of the three studies that evaluated skin colonization reported a significant OR of 4.16 (95 % CI 1.74-9.94). A relation between nasal colonization and acne was not found. Limitations in study design and low sample sizes should be taken into consideration when interpreting the results. Colonisation with S. aureus seems to be increased in patients with psoriasis. This bacterial species, known for its potential to induce long-lasting inflammation, might be involved in psoriasis pathogenesis. Information on acne is limited. Prospective controlled studies should further investigate the role of S. aureus in chronic inflammatory skin diseases.

    PubMed

    Perry, Alexandra; Lambert, Peter

    2011-12-01

    Propionibacterium acnes is a Gram-positive bacterium that forms part of the normal flora of the skin, oral cavity, large intestine, the conjunctiva and the external ear canal. Although primarily recognized for its role in acne, P. acnes is an opportunistic pathogen, causing a range of postoperative and device-related infections. These include infections of the bones and joints, mouth, eye and brain. Device-related infections include those of joint prostheses, shunts and prosthetic heart valves. P. acnes may play a role in other conditions, including inflammation of the prostate leading to cancer, SAPHO (synovitis, acne, pustulosis, hyperostosis, osteitis) syndrome, sarcoidosis and sciatica. If an active role in these conditions is established there are major implications for diagnosis, treatment and protection. Genome sequencing of the organism has provided an insight into the pathogenic potential and virulence of P. acnes.

    Laser Doppler flowmetry discovered microcirculatory disorders in acne patients. Affected are arterioles as well as capillaries and venules. Combination of magnetotherapy with medication improves microcirculation in acne patients. More marked positive changes occurred in the microcirculatory system due to combined treatment compared to medication therapy only. Thus, laser Doppler flowmetry is a new, noninvasive method of assessing microcirculation in acne patients and can serve an objective criterion of treatment efficacy.

    2016-11-01

    Multifocal osteomyelitis and synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome constitute a spectrum of disease that includes inflammatory bone lesions and dermatologic findings. Radiographic features resemble those of the spondyloarthropathies with anterior chest wall involvement. Early radiographic findings are osteodestructive with lytic lesions. Bone scintigraphy of the sternoclavicular region classically yields a 'bull's head' pattern of radionuclide uptake. Magnetic resonance imaging (MRI) can demonstrate corner lesions of vertebral bodies. Ultrasound often reveals peripheral enthesitis. Late radiographic features are usually osteoproliferative. PET/CT can identify chronic lesions. Differential diagnostic considerations include osteomyelitis and malignancy, which often prompt bone biopsy.

    2012-01-01

    Acne is a common dermatological disorder that most frequently affects adolescents; however, individuals may be affected at all ages. Many people who suffer from acne seek treatment from both prescription and over-the-counter acne medications. Due to convenience, lower cost, and difficulty getting an appointment with a dermatologist, the use of over-the-counter acne treatments is on the rise. As the plethora of over-the-counter acne treatment options can be overwhelming, it is important that dermatologists are well-versed on this subject to provide appropriate information about treatment regimens and potential drug interactions and that their patients see them as well-informed. This article reviews the efficacy of various over-the-counter acne treatments based on the current literature. A thorough literature review revealed there are many types of over-the-counter acne treatments and each are designed to target at least one of the pathogenic pathways that are reported to be involved in the development of acne lesions. Many of the key over-the-counter ingredients are incorporated in different formulations to broaden the spectrum and consumer appeal of available products. Unfortunately, many over-the-counter products are not well-supported by clinical studies, with a conspicuous absence of double-blind or investigator-blind, randomized, vehicle-controlled studies. Most studies that do exist on over-the-counter acne products are often funded by the manufacturer. Use of over-the-counter acne treatments is a mainstay in our society and it is important that dermatologists are knowledgeable about the different options, including potential benefits and limitations. Overall, over-the-counter acne therapies can be classified into the following five major groups: cleansers, leave-on products, mechanical treatments, essential oils, and vitamins. PMID:22808307

    Acne is a problem of the pilo-sebaceous follicle caused by the conjunction of three factors: seborrhea, follicle obstruction, and follicle inflammation. The key element, seborrhea, is under androgenic control. Acne in women is also influenced by developments and modifications in genital life, as well as by hormonal contraceptive and replacement therapies. Acne is rare prior to puberty, when it may indicate endocrine disease. At puberty, acne is quasi-physiological, because of the relative hyperandrogenism induced by the andrenarche preceding pubarche, as well as by the relative shortage of estrogens and progesterone during the first menstrual cycles. Other signs of hyperandrogenism, such as menstrual cycle difficulties and excess weight, which favor a hormonal origin, must be sought in cases of persistent or late-onset acne in adults. There is a mirror image of puberty during the peri-menopausal period, but with decreased seborrhea, so acne is rare. Finally, a tumoral origin must be sought in the rare cases of acne occurring after menopause. Hormonal investigation of acne should not be systematic, but is justified during prepuberty when other symptoms are associated with acne that resists well-conducted dermatological treatment. The therapeutic approach should be primarily dermatological, but hormone-oriented treatment should be considered when such therapy fails, or in the presence of other signs of hyperandrogenism. Sometimes the association of isotretinoin and an anti-androgen treatment are necessary to effectively treat such acne. Finally, particular attention must be paid to contraceptive therapies and hormone treatments, which can induce or aggravate acne, especially during the peri-menopausal period.

    Acne is an intriguing model for the study of interactions between hormones, innate immunity, inflammation and wound healing (scarring). The manifestations and involvement of acne in different systemic diseases and some rare syndromes demonstrate its multifaceted nature. Synovitis-Acne-Pustulosis-Hyperostosis-Osteitis (SAPHO) and Pyogenic Arthritis-Pyoderma gangrenosum-Acne (PAPA) syndromes, both regarded as autoinflammatory diseases, highlight the attributes of inflammation in acne. While SAPHO syndrome can be used to explore the pathogenic role of Propionibacterium acnes in acne, PAPA syndrome and Apert syndrome can help understand the genetic influence on acne. The genetic defects in the gain-of-function of FGFR2 mutations in Apert syndrome and acne nevus of Munro lend further support to the hypothesis that the interaction of forkhead box class O (FoxOs)-mediated transcriptional regulation with androgen receptor transactivation and insulin/insulin like growth factor-1(IGF-1)-signaling is crucial in acne pathogenesis. Novel biologics, such as tumor necrosis factor (TNF) blockers and IL-1 inhibitors, appear promising in opposing the inflammation associated with SAPHO and PAPA syndromes, but it remains to seen if they can also improve severe acne particularly in the long term.

    Infantile acne is a rare occurrence. It is more common in boys and predominately occurs on the cheeks in infants between the ages of 1 and 16 months. Clinically, the lesions range from comedones to inflammatory papulopustules to cysts. Successful therapies include topical tretinoin, benzoyl peroxide and topical and oral erythromycin. For more serious cases, oral isotretinoin (Accutane) has been reported to successfully treat recalcitrant infantile cystic acne. We describe two additional patients with infantile cystic acne treated successfully with oral isotretinoin. The dose of isotretinoin used ranged from 0.2 mg/kg/day to 1.5 mg/kg/day. The treatment duration varied from 5 to 14 months. Careful monthly monitoring is recommended because of the many side effects reported with isotretinoin. Practical tips for the administration of oral isotretinoin in infants are reviewed.

  19. An update on the role of the sebaceous gland in the pathogenesis of acne

    The pathogenesis of acne, a disease of the pilosebaceous follicle and one of the most common chronic skin disorders, is attributed to multiple factors such as increased sebum production, alteration of the quality of sebum lipids, inflammatory processes, dysregulation of the hormone microenvironment, interaction with neuropeptides, follicular hyperkeratinisation and the proliferation of Propionibacterium acnes within the follicle. In particular, the sebaceous gland plays an exquisite role in the initiation of the disease as it possesses all the enzyme machinery for the production of hormones and cytokines. In addition, in response to the altered tissue environment in the pilosebaceous follicle as well as in answer to emotional fret, stress response system mechanisms with induction of central and local expression of neuropeptides, are also initiated. This review summarises the latest advances in understanding the role of sebaceous gland cells in the pathomechanism of acne. PMID:21519409

    2004-05-01

    Common acne is steatorrhoeic chronic disease, to which specific is, among others, the presence of blackheads, papulopustular eruptions, purulent cysts and cicatrices. Such hormonal factors belong to elements inherent in etiology of the affection. Sebaceous glands have cell receptors on their surface for androgens. In etiopathogenesis of common/simple acne, a decisive role is played by a derivative of testosterone, i.e. 5-alpha-dihydrotestosterone (DHT). However, some experts are of opinion that there is no correlation between the increased intensity of common acne and other symptoms of hyperandrogenism. Numerous authors assume, however, that common acne-affected patients may be sometimes subjected to intense reactions caused by sebaceous glands against physiological androgens concentrations. Naturally, estrogens can inhibit release of such androgens. Under physiological conditions, natural progesterone does not conduct to intensification of the seborrhea, but the activity of sebum secretion may be triggered off by its synthetic counterparts. Hormonal etiology can be very distinctly visible in the steroid, androgenic, premenstrual, menopausal acne, as well as in juvenile acne and acne neonatorum. In case of females affected by acne, hormonal therapy should be persistently supported and consulted with dermatologists, endocrinologists and gynecologists. Antiandrogenic preparations are applied, such as: cyproterone acetate concurrently administered with estrogens and, as well as not so frequently with chlormadinone acetate (independently or during estrogenic therapy).

    Background. Prosthetic joint infections (PJIs) significantly complicate joint arthroplasties. Propionibacterium acnes is an increasingly recognized PJI pathogen, yet limited clinical and therapeutic data exist. We sought to examine characteristics of P. acnes shoulder PJIs and compare surgical and nonsurgical management outcomes. Methods. A retrospective analysis of P. acnes shoulder PJIs was conducted at an academic center in Baltimore, Maryland from 2000 to 2013. Results. Of 24 cases of P. acnes shoulder PJIs, 92% were diagnosed after extended culture implementation; 42% in the delayed and 46% in the late postsurgical period. Joint pain and diminished function were the predominant presenting clinical signs. Erythrocyte sedimentation rate and C-reactive protein elevations occurred in 47% and 44%, respectively. All tested isolates were susceptible to β-lactams, moxifloxacin, vancomycin, and rifampin. Clindamycin resistance was identified in 6%. Of the antibiotic-only treated cases, 67% had a favorable clinical outcome compared with 71% (P = 1.0) of cases with a combined antibiotic-surgical approach. Favorable outcome with and without rifampin therapy was 73% and 60% (P = .61), respectively. Conclusions. Propionibacterium acnes PJI diagnoses increased with extended culture. Inflammatory markers were elevated in a minority of cases. Isolates maintained broad antimicrobial susceptibility. Compared to combined antibiotic-surgical approaches, antibiotic-only approaches were similarly successful in selected cases. PMID:26933665

    Background Lipid peroxide (LPO) in comedones, which are produced as a result of sebum oxidation, might potentially induce interleukin-1α (IL-1α) and exacerbate comedogenesis and inflammatory changes in comedones. Objective To investigate the relationship of proinflammatory cytokines and LPO levels in the extracts of comedones with the acne of clinical difference between smokers and non-smokers, and with the severity and distribution of the acne lesions. Methods Twenty-two non-smoking and 21 smoking adult acne patients were evaluated by comedone extraction and measurement of proinflammatory cytokines and LPO levels. Acne severity and distribution of the lesions were also analyzed. Results Relative to the non-smoking group, smokers had significantly higher levels of IL-1α and LPO in comedones. Their levels showed a positive correlation. However, there were no statistically significant difference between the severity or distribution of the disease and the levels of LPO and IL-1α in comedones. Conclusion Smoking may be involved in the pathogenesis of adult acne by increasing the oxidative stress that results in subsequent accumulation of LPO in comedones. PMID:24648681

    Chemical peeling implies the application of a chemical agent to the skin, which causes controlled destruction of a part or the entire epidermis, with or without the dermis, leading to exfoliation and removal of superficial lesions, followed by regeneration of new epidermal and dermal tissues. The present study was directed toward safety concerns associated with superficial chemical peeling with glycolic acid (GA) in different concentrations at patients with acne tip I. A sample of 90 patients of either sex, aged between 17 to 21 years, were included in the study and submitted to superficial chemical peeling for acne vulgaris. The study lasted eight weeks and peeling sessions were carried out in each patient. Tolerance to the procedure and any undesirable effects noted during these sessions were recorded. For data statistical analysis and interpretation of results, software program "SPSS version 13" was used. Results were expressed through the descriptive statistics, as simple frequencies and percentages, while for establishing of statistically significant differences, in use was Friedman's test of significance. Almost all the patients tolerated the procedure well. Of totally 90 patients, only six, at the end of therapy experienced hard erythema, only ten, at the end of therapy experienced hard desquamation and only eleven, at the end of therapy experienced hard sensation of pulling of facial skin. Chemical peeling with glycolic acid is a well tolerated and safe treatment modality in acne type I.

    Background Evidence regarding what comprises effective education for acne vulgaris patients is lacking. Internet-based education may improve patient knowledge of this condition. Objectives Our objective was to compare the effectiveness of standard web-based education and an automated counseling website in improving acne knowledge. Design In a randomized trial, participants visited either a standard website or an automated counseling website to learn about acne. Multiple-choice questions were administered at baseline and after 12 weeks to assess change in acne knowledge. Results A total of 97 high school students were enrolled, and 95 completed the study. The standard website group had a significant increase in knowledge from baseline (3.61 ± 1.22) to 12-week follow-up (5.46 ± 1.31, p < 0.001). Similarly, the automated counseling website group had a significant increase in knowledge between both time points (3.53 ± 1.50 vs. 6.49 ± 1.06, p < 0.001). After 12 weeks, mean improvement in knowledge was higher in the automated counseling group (2.96 ± 1.85) than in the standard website group (1.85 ± 1.46, d = 0.67, p = 0.002). The number of website visits was positively correlated with improvement in knowledge in both groups. Finally, the automated counseling website group rated their educational material more useful (p = 0.004) and more enjoyable to view (p = 0.003) than did the standard website group. Limitations This study is limited to adolescents with mild-to-moderate acne vulgaris. Conclusion Internet-based patient education appears to be an effective method of improving acne knowledge among adolescents. PMID:25502610

    In a recent study, prostatectomy specimens from which Propionibacterium acnes was cultured were more likely to have inflammation than culture-negative specimens or specimens positive for other bacteria, leading the authors to hypothesize that P. acnes-mediated inflammation may contribute to prostate carcinogenesis. To indirectly explore associations between P. acnes and prostate cancer, we investigated severe acne, as measured by tetracycline use for 4 or more years, in relation to incident prostate cancer in the Health Professionals Follow-up Study. On the 1992 follow-up questionnaire, participants were asked whether they had ever used "tetracycline for at least 2 months at a time (e.g., for acne or other reason)" and their duration of use. Prostate cancer diagnoses were ascertained on each subsequent biennial questionnaire and confirmed by medical record review. Between 1992 and 2002, 2,147 cases of prostate cancer were reported among 34,629 eligible participants. Men who used tetracycline for 4 or more years had a significantly higher risk of prostate cancer (16 cases, 1,569 person-years) than men who did not use tetracycline (2,071 cases, 304,822 person-years, multivariable-adjusted RR = 1.70, 95% CI: 1.03-2.80). Although intriguing, this finding should be viewed cautiously because of the small number of exposed cases, indirect assessment of severe acne, and complex etiology of acne, which is not limited to P. acnes infection. Therefore, additional biologic and epidemiologic studies are necessary to determine and elucidate the possible role of P. acnes infection in prostate carcinogenesis.

    The human skin microbiome has important roles in skin health and disease. However, bacterial population structure and diversity at the strain level is poorly understood. We compared the skin microbiome at the strain level and genome level of Propionibacterium acnes, a dominant skin commensal, between 49 acne patients and 52 healthy individuals by sampling the pilosebaceous units on their noses. Metagenomic analysis demonstrated that although the relative abundances of P. acnes were similar, the strain population structures were significantly different in the two cohorts. Certain strains were highly associated with acne, and other strains were enriched in healthy skin. By sequencing 66 previously unreported P. acnes strains and comparing 71 P. acnes genomes, we identified potential genetic determinants of various P. acnes strains in association with acne or health. Our analysis suggests that acquired DNA sequences and bacterial immune elements may have roles in determining virulence properties of P. acnes strains, and some could be future targets for therapeutic interventions. This study demonstrates a previously unreported paradigm of commensal strain populations that could explain the pathogenesis of human diseases. It underscores the importance of strain-level analysis of the human microbiome to define the role of commensals in health and disease.

    Acne vulgaris is the chronical, multifactorial and complex disease of the pilosebaceous unit in the skin. The main goal of the topical therapy in acne is to target the drug to epidermal and deep dermal regions by minimizing systemic absorption . Isotretinoin, a retinoic acid derivative, is the most effective drug in acne pathogenesis. Because systemic treatment may cause many side effects, topical isotretinoin treatment is an option in the management of acne. However, due to its high lipophilic character, isotretinoin tends to accumulate in the upper stratum corneum, thus its penetration into the lower layers is limited, which restricts the efficiency of topical treatment. Microemulsions are fluid, isotropic, colloidal drug carriers that have been widely studied as drug delivery systems. The percutaneous transport of active agents can be enhanced by microemulsions when compared with their conventional formulations. The purpose of this study was to evaluate microemulsions as alternative topical carriers for isotretinoin with an objective to improve its skin uptake. After in vitro permeation studies, the dermal penetration of isotretinoin from microemulsions was investigated by tape stripping procedure. Confocal laser scanning microscopy provided insight about the localization of the drug in the skin. The interaction between the microemulsion components and stratum corneum lipids is studied by ATR-FTIR spectroscopy. The relative safety of the microemulsions was assessed in mouse embryonic fibroblasts using MTT viability test. The results indicate that microemulsion-based novel colloidal carriers have a potential for enhanced skin delivery and localization of isotretinoin.

    2010-01-01

    Early acne can be defined as the occurrence of acne at its onset, primarily in preteens, or as acne at its earliest severity (ie, mild to moderate). Although the majority of patients with acne are treated by dermatologists, most, particularly mild to moderate cases, could be successfully managed by primary care physicians. Therefore, it is important for physicians to understand the benefits of treating all types of acne, not just the most severe. Awareness of the emotional impact of acne, particularly in adolescence, as well as recognition of possible scarring are important considerations. To achieve optimal results, physicians should be familiar with classification and severity grading of acne. Also, in-depth knowledge of available acne medications will streamline and optimize treatment regimens. Recognizing, treating, and monitoring the progress of early acne may lead to quicker, better clinical outcomes and improved quality of life.

    Dermabrasion offers cosmetic improvement of acne pits and scars, but only well-adjusted patients should be selected for this esthetic improvement. In the dermabrasion operation the deep cup-shaped pits are made shallow by saucerization, for the deep sharp shadows are eliminated as the pits are shallowed. It is the elimination of the shadow effect which is so gratifying to the patient. Although dermabrasion is a superficial skin operation, it involves dangerous instruments and thousands of minute incisions. The procedure is a surgical operation, whether done in an office or in a hospital. The author performs the operation entirely as a hospital procedure, using pentothal anesthesia with meperidine added in small increments during the operation.

    Pyoderma gangrenosum, cystic acne, and aseptic arthritis are clinically distinct disorders within the broad class of inflammatory diseases. Although this triad of symptoms is rarely observed in a single patient, a three-generation kindred with autosomal-dominant transmission of these three disorders has been reported as "PAPA syndrome" (MIM 604416). We report mapping of a disease locus for familial pyoderma gangrenosum-acne-arthritis to the long arm of chromosome 15 (maximum two-point LOD score, 5.83; recombination fraction [straight theta] 0 at locus D15S206). Under the assumption of complete penetrance, haplotype analysis of recombination events defined a disease interval of 10 cM, between D15S1023 and D15S979. Successful identification of a single disease locus for this syndrome suggests that these clinically distinct disorders may share a genetic etiology. These data further indicate the role of genes outside the major histocompatibility locus in inflammatory disease.

    Background: Oral isotretinoin treatment might influence the levels of vitamin B12 and folic acid. Aims and Objectives: The aim of this study is to compare vitamin B12 and folic acid levels in patients with moderate and severe acne vulgaris with those of the healthy control group and to investigate the effect of isotretinoin treatment on these vitamins. Materials and Methods: Patients who completed 6 months of isotretinoin therapy for moderate and severe forms of acne vulgaris and a control group consisting of healthy individuals between February 2011 and March 2012 were included in the study. Before isotretinoin therapy and at 6.- months of the therapy, serum vitamin B12 and folic acid levels were measured. In the healthy control group, vitamin B12 and folic acid levels were assessed only once. Results: In total, 120 patients with moderate and severe acne vulgaris who completed 6 months isotretinoin therapy and 100 healthy individuals who constituted the control group were included in the study. Pre-treatment vitamin B12 values of the patient group were found to be statistically significantly higher (P = 0.002), but any statistically significant difference was not detected in folic acid measurements (P = 0.566). A statistically significant decrease was detected in post-treatment vitamin B12 and folic acid levels (P < 0.05). Conclusion: Vitamin B12/folic acid treatment should be given under medical surveillance before and during isotretinoin therapy. Supplementation of these vitamins should be recommended in cases of their deficiency, so as to decrease the risks of neuropsychiatric and occlusive vascular diseases. PMID:25484410

    Objective: Treatment of acne scarring is always a challenge. Microneedling therapy or percutaneous collagen induction is a new addition to the treatment modalities for such scars and has been reported to be simple and effective in atrophic acne scar treatment. The aim of this study is to evaluate the clinical effect and objectively quantify the histological changes of acne scarring in response to skin microneedling. Design: A prospective clinical study. Participants: Ten patients with different types of atrophic acne scars were subjected to three months of skin microneedling treatment (six sessions at two-week intervals). Measurements: Patients were photographed, and skin biopsies were obtained at baseline as well as one and three months from the start of treatment. Histometry for epidermal thickness and quantitative evaluation of total elastin; newly synthesized tropoelastin; collagen types I, III, and VII; and newly synthesized collagen were performed for all biopsies. Results: Compared to the baseline, patients’ evaluations revealed noticeable clinical improvement in atrophic post-acne scars in response to skin microneedling. There was a statistically significant increase (p<0.05) in the mean of collagen types I, III, and VII and newly synthesized collagen, while total elastin was significantly decreased (p<0.05) after the end of treatment. Conclusions: Multiple minimally invasive sessions of skin microneedling are an effective treatment for post-acne atrophic scars as it stimulates the repair processes with the advantage of being a relatively risk-free, in-office procedure with minimal patient recovery time.

    Propionibacterium acnes induction of IL-1 cytokines through the NLRP3 inflammasome was recently highlighted as a dominant etiological factor for acne vulgaris. Therefore, therapeutics targeting both the stimulus and the cascade would be ideal. Nitric oxide (NO), a potent biological messenger, has documented broad-spectrum antimicrobial and immunomodulatory properties. To harness these characteristics to target acne, we utilized an established nanotechnology capable of generating/releasing nitric oxide over time (NO-np). P. acnes was found to be highly sensitive to all concentrations of NO-np tested, though human keratinocyte, monocyte, and embryonic zebra fish assays revealed no cytotoxicity. NO-np significantly suppressed IL-1β, TNF-α, IL-8 and IL-6 from human monocytes and IL-8 and IL-6 from human keratinocytes respectively. Importantly, silencing of NLRP3 expression by small interfering RNA did not limit NO-np inhibition of IL-1 β secretion from monocytes, and neither TNF-α, nor IL-6 secretion nor inhibition by NO-np was found to be dependent on this pathway. The observed mechanism by which NO-np impacts IL-1β secretion was through inhibition of caspase-1 and IL-1β gene expression. Together, these data suggest that NO-np can effectively prevent P. acnes induced inflammation by both clearing the organism and inhibiting microbial stimulation of the innate immune response.

    2016-11-01

    Acne fulminans (AF) is a rare manifestation and the most severe form of the entire clinical spectrum of acne. The disease is destructive and is characterized by the sudden onset of painful and ulcerative pustules and systemic symptoms including high fever, hepatomegaly, polyarthralgia, leukocytosis, plaquetose, and increased inflammatory markers and transaminases. Osteolytic lesions in multiple skeletal sites could also be associated. The use of isotretinoin is considered a related trigger, as well as the use and cessation of testosterone, although a bacterial infection, a drug-induced disease, or an intake of anabolic androgenic steroids has been suggested. The treatment of AF is challenging and controversial. The recommended treatment is aggressive and consists of a combination of oral steroids and low doses of isotretinoin, with no consensus at this time. The patient may require several weeks of hospitalization to control the eruption. The cutaneous lesions usually leave scars and milia. We report on two boys and two girls presenting with AF, triggered by isotretinoin in three patients and by an antibiotic in one patient. All the patients treated with corticosteroids and isotretinoin with success.

    We describe the case of a 63-year-old female who presented with severe inflammatory spondylitis, refractory to various antibiotics. Mycobacterial and fungal osteomyelitis were unlikely. Although asymptomatic, she also had osteomyelitis in the sternocostoclavicular region, and was suspected of having synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome, against which minocycline showed marked efficacy. The presence of severe inflammatory SAPHO, albeit rare, together with the marked efficacy of tetracycline, should be noted.

    Tuberculosis is a major public health problem in both developing and developed countries. Cutaneous Tuberculosis constitutes a minor proportion of extra-pulmonary manifestations of Tuberculosis. Lupus Vulgaris (LV) is one of the clinical variants of Cutaneous Tuberculosis. A case of a large plaque type psoriasiform lesion of lupus vulgaris on the thigh, of 15 years' duration, in an 18-year-old girl is reported. This case highlights the ignorance level among the patients and consequent failure to avail proper anti-tuberculous treatment despite campaign in print and audio visual media.

    Tyrell Inc., a Houston-based medical technologies company, was able to access engineering support in redesigning a heating element for a hand-held acne-fighting device through SATOP, NASA's Space Alliance Technology Outreach Program. SATOP put Tyrell in contact with The Boeing Company, which assessed the design and made several major contributions. The product, named Zeno, is now the highest selling over-the-counter medical device for the treatment of acne, and in 2006, Zeno was named the "SATOP Texas, Success Story of the Year." Zeno employs proprietary ClearPoint technology to provide relief of mild to moderate inflammatory acne by delivering a precisely controlled low-level dosage of heat to the blemish, causing the bacteria at the root of more than 90 percent of acne to self-destruct. Within its first year on the market, Zeno was cited by various publications for several awards, including Allure's 2005 "Best of Beauty," Marie Claire's "10 Best Gadgets for Girls," and Popular Science's 2005 "Best of What's New." A variation of the Zeno for use in treating herpetic lesions such as cold sores, by killing the virus that causes them, is currently undergoing FDA trials.

    Acne is a chronic inflammatory skin disease pilosebaceous follicle, where the oil- producing glands are clogged and contaminated by bacteria. Propionibacterium acne is one of the bacteria that contributes to the pathogenesis of acne. Acne treatment was done by reducing the population of bacteria using an antibacterial. One of the plants that have antibacterial activity is white plumeria. The ethanol extract of white plumeria leaves contains antibacterial secondary metabolites, which are alkaloids and saponins. The aim of this study is to formulate white plumeria leaves extract into the water leached ointment base. Characteristics of the ointment were determined by evaluating the stability of the ointment including organoleptic, adhesion test, dispersive power test, determination of pH, and the antibacterial activity test. The results showed that the ointment of ethanol extract of white plumeria leaves has some characteristics, semisolid form, white, has distinctive smell of ointment, homogeneous but not protective, has a pH of 4.57 - 6.10, dispersive power of 5.10 - 6.06 cm, the adhesiveness of 1.67 - 3 seconds, and optimum antibacterial activity at concentrations of 5 ppm providing inhibition zone of 24.00 mm.

  5. Differential inflammatory response to acrylonitrile in rat primary astrocytes and microglia.

    Acrylonitrile (ACN) is extensively used in the production of plastics, resins, nitriles and other commercial products. Chronic low dose exposures to ACN cause glial cell tumors in rats, primarily microglial in origin. Recently it has been determined that astrocytes and microglia respond to ACN-induced oxidative stress differently, which may influence cell-specific activation of inflammatory and carcinogenic pathways. This study was conducted to compare the inflammatory responses of astrocytes and microglia following ACN treatment in vitro to further characterize differential sensitivities and adaptive responses in these cell types. Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and p53 levels were measured along with levels of 12 different cytokines and chemokines in primary rat microglia and astrocytes. Additionally levels of cytochrome P450 2E1 (CYP2E1) were measured to evaluate the cells' ability to metabolize ACN. Results indicate that while both cells upregulate p53 and NF-κB, the cytokines and chemokines produced differ between the cell types. Astrocytes, but not microglia, upregulated CYP2E1 in response to ACN, which may be due to the astrocytes accumulating more ACN than the microglia. Altogether our data implicate the inflammatory response as an important event in ACN-induced neurotoxicity.

    Psoriasis vulgaris is an autoimmune chronic inflammatory skin disease, but its association with other typical autoimmune disease such as systemic lupus erythematosus has only occasionally been reported. We presented a 25-year-old female who developed systemic lupus erythematosus associated with psoriasis vulgaris. Her conditions were in good control after she got administration of prednisolone (5 mg/day) and Tripterygium Wilfordii Hook (20 mg/day). It is necessary to integrate past history and physical examination to diagnose coincident SLE and psoriasis, and combined treatment with prednisolone and Tripterygium Wilfordii Hook proves effective.

    We examined the relationship between Propionibacterium acnes biotypes and Jumi-haidoku-to (JHT). In all the P. acnes strains tested, the production of propionic acid (PA) and butyric acid (BA) was suppressed in a medium containing 1 mg/ml JHT compared with the control medium without JHT. There were no significant differences in the rates of decreased PA and BA production between P. acnes biotype 3 (B3) and the other biotypes or between isolates from mild skin rash and more severe skin rash. P. acnes B3 was the most commonly identified biotype. The clinical effects on acne due to the anti-P. acnes lipase activity of JHT did not seem to be influenced by the degree of acne rash or the P. acnes biotype.

    A pilot study was conducted to compare lipid components of sebum from unaffected and acne-affected individuals. Nine males, 15–20 years old, with no acne, or with moderate to severe acne, were recruited. Facial images were taken with regular, polarized and fluorescent lights for each subject. Skin surface lipids were analyzed following collection of sebum using sebutapes. As expected, the subjects with acne had more (59%) sebum than the control subjects. Free fatty acids were the only lipid group that was reduced in the sebum of acne subjects. The specific lipid that differed the most between the two groups was squalene, which was upregulated in acne subjects by 2.2-fold on a quantitative basis. Squalene also represented a significantly greater proportion of the total sebaceous lipids in acne patients compared to controls (20% vs. 15%). The increase in the amount of squalene could represent a lipid marker for acne prone skin. PMID:20436883

    Acne and rosacea are common skin diseases which may present similarly and both involve inflammation. Both can result in significant cosmetic impairment and lead to quality of life decrements if not optimally treated. The conventional approach for both diseases involves the use of topical therapy to treat inflammatory lesions in combination, when needed, with a systemic or topical antibiotic. An important issue in the management of both diseases at present is the need to reduce antibiotic usage due to the increasing problem of bacterial resistance. One of the emerging treatment paradigms that is becoming increasingly useful as an antibiotic-sparing strategy is the use of procedural therapies in combination with medical management. Such procedural modalities include lasers, intense pulsed light (IPL), and photodynamic therapies (PDT). Topical regimens are used pre-treatment and following physical modalities for maintenance of remission.

    Autoinflammatory disorders are a group of Mendelian disorders characterized by seemingly unprovoked inflammatory bouts without high-titer autoantibodies or antigen-specific T-cells and are probably due to defects in the innate immunity. We here report on a 4-year-old Arabic boy with the clinical presentation of an autoinflammatory disorder, namely Pyogenic Arthritis, Pyoderma Gangrenosum and Acne (PAPA) syndrome. The presentation includes abscess formation after immunization and recurrent mono-articular acute arthritis in various joints that responded favourably to systemic glucocorticosteroids, albeit without acne or pyoderma gangrenosum. The mutation analysis of the boy identified a novel de novo mutation in PSTPIP1, the gene responsible for PAPA syndrome. We recommend that the diagnosis of PAPA syndrome should be entertained in the differential diagnosis of patients with recurrent sterile pyogenic arthritis prior to the development of pyoderma gangrenosum or acne in order to initiate a timely management of the disorder.

  19. Identification of AcnR, a TetR-type repressor of the aconitase gene acn in Corynebacterium glutamicum.

    PubMed

    Krug, Andreas; Wendisch, Volker F; Bott, Michael

    2005-01-07

    In Corynebacterium glutamicum, the activity of aconitase is 2.5-4-fold higher on propionate, citrate, or acetate than on glucose. Here we show that this variation is caused by transcriptional regulation. In search for putative regulators, a gene (acnR) encoding a TetR-type transcriptional regulator was found to be encoded immediately downstream of the aconitase gene (acn) in C. glutamicum. Deletion of the acnR gene led to a 5-fold increased acn-mRNA level and a 5-fold increased aconitase activity, suggesting that AcnR functions as repressor of acn expression. DNA microarray analyses indicated that acn is the primary target gene of AcnR in the C. glutamicum genome. Purified AcnR was shown to be a homodimer, which binds to the acn promoter in the region from -11 to -28 relative to the transcription start. It thus presumably acts by interfering with the binding of RNA polymerase. The acn-acnR organization is conserved in all corynebacteria and mycobacteria with known genome sequence and a putative AcnR consensus binding motif (CAGNACnnncGTACTG) was identified in the corresponding acn upstream regions. Mutations within this motif inhibited AcnR binding. Because the activities of citrate synthase and isocitrate dehydrogenase were previously reported not to be increased during growth on acetate, our data indicate that aconitase is a major control point of tricarboxylic acid cycle activity in C. glutamicum, and they identify AcnR as the first transcriptional regulator of a tricarboxylic acid cycle gene in the Corynebacterianeae.

  20. Autoreactive T cells in the immune pathogenesis of pemphigus vulgaris.

    PubMed

    2013-11-01

    Pemphigus vulgaris is a life-threatening autoimmune blistering disease caused by anti-desmoglein IgG autoantibodies that finally lead to acantholysis presenting clinically as progressive blistering. Whilst the production of pathogenic antibodies is key to the development of pemphigus vulgaris, many immunological steps are required prior to autoantibody induction. We review advances in the understanding of these immunologic processes with a focus on human leucocyte antigen polymorphisms and antigen recognition, epitope spreading, central and peripheral tolerance, T helper differentiation, induction of pro- and anti-inflammatory cytokines and T-cell regulation of B cells. Targeting autoaggressive T cells as regulators and stimulators of B-cell antibody production should allow for more specific therapeutic immune interventions, avoiding the global immunosuppression seen with many commonly used immunosuppressants in pemphigus vulgaris.

    Prednisolone combined with erythromycin was given to 6 patients with cystic acne. The treatment responses were compared to those in 6 patients with cystic acne receiving isotretinoin and erythromycin and also to those in 3 patients with acne fulminans treated with prednisolone and erythromycin. During the first 4 weeks cystic acne showed a clear improvement in 5 out of 6 patients in both treatment groups. A similar improvement occurred in all 3 patients with acne fulminans. When corticosteroid was stopped, 2 out of 5 patients with cystic acne had a relapse and needed isotretinoin for complete control. In the isotretinoin-treated group, one patient with cystic acne needed prednisolone because the acne worsened to an ulcerative form. Slightly elevated liver enzymes, possibly due to erythromycin treatment, were observed in 2 patients with cystic acne and in one patient with acne fulminans. The present results show that prednisolone combined with erythromycin is an effective treatment during the early stages of cystic and febrile acne, but isotretinoin is needed for long-term control.

    Photodynamic therapy (PDT) is an attractive alternative treatment for patients with acne because of its efficiency and few side effects. Propionibacterium acnes (P.acnes) are bacteria present in the skin, which produce endogenous porphyrins that act as photosensitisers. In addition, application of aminolaevulinic acid or its methyl ester (mALA) results in increased accumulation of porphyrins in the pilosebaceous units. This makes it possible to treat acne with PDT. This initial study investigates the possibility of fluorescence imaging as assessment tool in adjunct to PDT of patients with acne. Twenty-four patients with acne on the cheeks have been treated with PDT with and without mALA. Fluorescence images have been obtained before and after treatment. The clinical acne score was assessed as base line before PDT, and at every follow up visit. Additionally the amount of P.acnes was determined. The clinical evaluation showed a general improvement of acne, even though no difference between treatment with and without mALA was observed. By performing texture analysis and multivariate data analsysis on the fluorescence images, the extracted texture features were found to correlate with the corresponding clinical assessment (67%) and amount of P.acnes (72%). The analysis showed that features describing the highly fluorescent pores could be related to the clinical assessment. This result suggests that fluorescence imaging can be used as an objective assessment of acne, but further improvement of the technique is possible, for example by including colour images.

    Acne necrotica is a disorder of adults of obscure aetiology, featuring repeated cropping of inflammatory papulonodules which rapidly necrotise, leaving varying degrees of superficial scarring with pathological features in early lesions of a necrotising lymphocytic folliculitis. A perceived diminishing interest in this entity in recent years prompted a prospective study of patients presenting to a dermatology practice over a 3-year period to reassess the prevalence of this disorder in general dermatological patients, leading to the identification of 47 patients (35 female) with features of acne necrotica, with histopathology undertaken in atypical cases. We identified the importance of the recognition of primary lesions (1-2 mm umbilicated erythematous papules), often difficult to find in excoriated areas, as being paramount in the diagnosis both clinically and histologically in our study, which reveals a significantly more prevalent and clinically diverse disorder than featured in previous textbook and academic journal descriptions.

    Lupus vulgaris is chronic, postprimary, paucibacillary cutaneous tuberculosis found in individuals with moderate immunity and high degree of tuberculin sensitivity. Eighty percent of the lesions are on the head and neck. We present the case of a 38 year old lady who was admitted with complaints of worsening breathlessness and low grade fever of one month duration. Examination showed multiple, nontender skin ulcers on bilateral lumbar areas, two oozing serosanguinous discharge and others scarred in the centre. Respiratory system examination and chest X-ray revealed right sided pleural effusion. On investigation, pleural fluid was tuberculous in nature. Skin biopsy from the edge of ulcer was also suggestive of tuberculosis. Patient is doing well on antituberculous drugs. This case highlights the importance of cutaneous manifestations of systemic disease and is an example of the unusual presentation of lupus vulgaris in a case of pleural effusion.

    2004-01-01

    Pemphigus is a chronic disease with an outcome that is not without risk. It is characterised by loss of the intraepithelial cell-cell relationship (acantholysis). Underlying the disease is an autoimmune disorder in which the desmosomes are damaged by antibodies directed against particular molecules called desmogleins (particularly 3 and 1). Various types of pemphigus have been described with different antibody profiles and clinical signs. In the present paper, a case of pemphigus vulgaris associated with the medication cefaclor monohydrate is reported. Histological and immunological evaluation of the biopsy sample led to a diagnosis of pemphigus vulgaris. The patient, who was not hospitalised, was treated with corticosteroids and systemic immunosuppressors. At present she is being controlled by low doses of systemic corticosteroids. Early diagnosis and the timely introduction of the therapeutic protocol permitted complete remission of the lesions observed at the level of the oral and conjunctival mucosa, preventing the involvement of other locations.

    We report the case of a 34-year-old woman who was diagnosed with pemphigus vulgaris (PV) during pregnancy. The patient presented with widespread blistering dermatitis and associated burning and pruritus. At 6 weeks' gestation the patient was admitted to the hospital to expedite her diagnosis and initiate treatment. A skin biopsy revealed suprabasal acantholysis, and direct immunofluorescence demonstrated diffuse intercellular IgG in the epidermis and basal intercellular C3, which confirmed the diagnosis of PV. Treatment with corticosteroids was instituted after discussions with the patient about possible adverse effects to the fetus. Pemphigus vulgaris is rare in pregnancy and active PV presents potential threats of fetal spread and transient lesion production, which is associated with increased mortality and morbidity in the fetus. Our patient had active PV and required treatment throughout her pregnancy. The pregnancy progressed to premature delivery of the neonate without skin lesions or apparent complications.

    Background Adherence to acne medication is poor and is a major reason why treatment plans are ineffective. Recognizing solutions to nonadherence is critical. Objective The purpose of this study is to describe the hurdles associated with acne nonadherence and to provide mechanisms on how to ameliorate them. Methods PubMed database was searched. Of the 419 search results, 29 articles were reviewed to identify hurdles to adherence and corresponding solutions. Results Hurdles to primary nonadherence where the medication is not even started, include lack of knowledge, confusion about usage, weak physician–patient relationship, fear of adverse reactions, and cost. Secondary nonadherence hurdles where the medication is started but is not taken as directed include lack of results, complex regimens, side effects, busy lifestyle, forgetfulness, inconvenience, and psychiatric comorbidity. Solutions to these hurdles include treatment simplification, technology, and dynamic education. Limitations Adherence is affected by numerous factors, but available literature analyzing acne adherence and interventions to improve adherence to treatment is limited. Conclusion There are several hurdles in adhering to acne treatment. Recognition of these hurdles and finding appropriate solutions may be as important to treatment outcomes as choosing the right medication to prescribe. PMID:27784999

  10. Hormonal correlates of acne and hirsutism.

    PubMed

    Lucky, A W

    1995-01-16

    Acne is a multifactorial disorder reflecting the role of infection, abnormal keratinization and immunologic reaction, as well as hormonal influences, on the pilosebaceous unit. Clinical studies have correlated elevated levels of androgens, originating in both the adrenal glands and ovaries, with acne. These include total and free testosterone, delta 4-androstenedione, dehydroepiandrosterone and its sulfate, and low levels of sex hormone binding globulin. The pathogenesis of acne initiation in childhood has been linked to rising serum levels of dehydroepiandrosterone sulfate. Hirsutism has been more directly correlated with increased levels of serum androgens, notably free testosterone. Underlying causes of elevated androgens in both disorders include very rare tumors, partial or late-onset forms of congenital adrenal hyperplasia, developmental adrenal abnormalities and, most commonly, polycystic ovary syndrome. Early acne treatment may include topical benzoyl peroxide, antibiotics, and tretinoin. More severe disease can be treated systemically (with antibiotics and/or isotretinoin). Very-low-dose corticosteroids can be used to eliminate the adrenal component of hyperandrogenism. Oral contraceptives, especially those that contain low-androgenic progestins, can reduce excessive androgens from any source and specifically suppress the ovary in polycystic ovary syndrome. Gonadotropin-releasing hormone agonists, with or without estrogen supplementation, and systemic or topical antiandrogens may play a more important role in the future.

    2009-12-01

    Treatment options for acne vulgaris have expanded considerably in the past decade. The main goals of treatment continue to be reducing acne lesions while maintaining patient satisfaction and adherence to treatment. As dermatologists, the art of treatment is to develop, fine-tune, and utilize combinations of agents to increase compliance, thereby optimizing patient outcomes. In acne management, one strategy involves concomitant use of topical retinoids with benzoyl peroxide or a fixed combination of topical antibiotic/benzoyl peroxide. This strategy requires application of one product in the morning and one in the evening due to concerns of benzoyl peroxide-induced degradation of retinoid activity. Presented are two cases in which a topical retinoid and a topical fixed combination of clindamycin/benzoyl peroxide were used concomitantly in patients with mild-to-moderate acne. Research-based and practical rationale on the simultaneous use of newer-generation retinoids and benzoyl peroxide-based products, without concern of retinoid degradation, is discussed.

  13. Recent advances in the use of adapalene 0.1%/benzoyl peroxide 2.5% to treat patients with moderate to severe acne.

    PubMed

    Leyden, James

    2016-01-01

    The central role of inflammation in acne is now more clearly understood. Adapalene, a third-generation topical retinoid, down-regulates toll-like receptor 2 expression and inhibits activator protein-1 activity. In a fixed-dose combination, adapalene and benzoyl peroxide (BPO) act synergistically on inflammatory patterns through regulation of innate immunity. In addition to reducing inflammatory and non-inflammatory lesions, adapalene/BPO helps prevent lesion and microcomedone formation. The combination of a topical retinoid and antimicrobial agent remains the preferred approach for almost all patients with acne. In cases of more severe disease, there is a clinical benefit in combining adapalene/BPO with an oral antibiotic for 12 weeks. Most recently, adapalene/BPO plus doxycycline 200 mg was found to be highly effective when compared with isotretinoin in the treatment of patients with severe acne with nodules. Long-term maintenance therapy is needed for most patients. Retinoids are the preferred agents, with BPO added in patients with more severe disease if needed. Adapalene is anticomedogenic, reduces comedones and has anti-inflammatory properties, while BPO is a unique antimicrobial agent not shown to induce microbial resistance after more than 50 years of use. Maintenance therapy for 6 months with adapalene/BPO prevents relapse among patients with severe acne and continues to reduce disease symptoms.
