    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 a chronic inflammatory disease - rather than a natural part of the life cycle as colloquially viewed - of the pilosebaceous unit (comprising the hair follicle, hair shaft and sebaceous gland) and is among the most common dermatological conditions worldwide. Some of the key mechanisms involved in the development of acne include disturbed sebaceous gland activity associated with hyperseborrhoea (that is, increased sebum production) and alterations in sebum fatty acid composition, dysregulation of the hormone microenvironment, interaction with neuropeptides, follicular hyperkeratinization, induction of inflammation and dysfunction of the innate and adaptive immunity. Grading of acne involves lesion counting and photographic methods. However, there is a lack of consensus on the exact grading criteria, which hampers the conduction and comparison of randomized controlled clinical trials evaluating treatments. Prevention of acne relies on the successful management of modifiable risk factors, such as underlying systemic diseases and lifestyle factors. Several treatments are available, but guidelines suffer from a lack of data to make evidence-based recommendations. In addition, the complex combination treatment regimens required to target different aspects of acne pathophysiology lead to poor adherence, which undermines treatment success. Acne commonly causes scarring and reduces the quality of life of patients. New treatment options with a shift towards targeting the early processes involved in acne development instead of suppressing the effects of end products will enhance our ability to improve the outcomes for patients with acne.

    Acne vulgaris is a chronic inflammatory disease of the pilosebaceous unit and it is observed equally in both sexes and nearly all races. It generally begins at puberty, but the healing period is variable. There is no known etiological factor, except genetic tendency. Androgens play a very limited role in some female patients. The effects of cosmetics, foods and drinks are also discussible and too limited. There are four factors in acne pathogenesis: Increase of the sebum excretionKeratinization of infrainfundibulumBacterial colonization of the follicleInflammation It is mainly observed on the face and back, shoulders and chest. Initial lesions are comedons. Papules, pustules and cysts of severe types follow it. The most important factor in treatment is a very good patient-physician communication. Topical or systemic treatment or both can be used depending on the severity of acne. Benzoyl peroxyde, azelaic acid, AHA’s antibiotics, retinoic acid and derivatives are the topical choices. For systemic treatment antibiotics are the most commonly used medicines, but isotretinoine has a very spesific place with the possibility of permanent healing. All kind of treatments need approximately six months for a good result. PMID:26078626

    Acne vulgaris is a common inflammatory chronic disease of the pilosebaceous unit. It often requires long-term treatment, resulting in increased demand for topical medications that are popular with patients in order to achieve long-term compliance. Tazarotene foam 0.1% is a novel formulation of tazarotene. We review efficacy and tolerability studies of the new formulation, and suggest a possible place for the product in the management of acne vulgaris. PMID:24920932

    Acne is a chronic inflammatory disease of the pilosebaceous unit resulting from androgen-induced increased sebum production, altered keratinisation, inflammation, and bacterial colonisation of hair follicles on the face, neck, chest, and back by Propionibacterium acnes. Although early colonisation with P acnes and family history might have important roles in the disease, exactly what triggers acne and how treatment affects the course of the disease remain unclear. Other factors such as diet have been implicated, but not proven. Facial scarring due to acne affects up to 20% of teenagers. Acne can persist into adulthood, with detrimental effects on self-esteem. There is no ideal treatment for acne, although a suitable regimen for reducing lesions can be found for most patients. Good quality evidence on comparative effectiveness of common topical and systemic acne therapies is scarce. Topical therapies including benzoyl peroxide, retinoids, and antibiotics when used in combination usually improve control of mild to moderate acne. Treatment with combined oral contraceptives can help women with acne. Patients with more severe inflammatory acne usually need oral antibiotics combined with topical benzoyl peroxide to decrease antibiotic-resistant organisms. Oral isotretinoin is the most effective therapy and is used early in severe disease, although its use is limited by teratogenicity and other side-effects. Availability, adverse effects, and cost, limit the use of photodynamic therapy. New research is needed into the therapeutic comparative effectiveness and safety of the many products available, and to better understand the natural history, subtypes, and triggers of acne.

    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. PMID:24807263

    The multifactorial etiology of acne vulgaris makes it challenging to treat. Current treatments include topical retinoids, benzoyl peroxide, topical and systemic antibiotics, azelaic acid, and systemic isotretinoin. Adjunctive and/or emerging approaches include topical dapsone, taurine bromamine, resveratrol, chemical peels, optical treatments, as well as complementary and alternative medications. The purpose of this paper is to discuss the therapies available for acne and their latest developments, including new treatment strategies (i.e. re-evaluation of the use of oral antibiotics and avoidance of topical antibiotic monotherapy, use of subantimicrobial antibiotic dosing, use of low-dose isotretinoin, optical treatments), new formulations (microsponges, liposomes, nanoemulsions, aerosol foams), new combinations (fixed-combination products of topical retinoids and topical antibiotics [essentially clindamycin] or benzoyl peroxide), new agents (topical dapsone, taurine bromamine, resveratrol) and their rationale and likely place in treatment. Acne vaccines, topical natural antimicrobial peptides, and lauric acid represent other promising therapies. PMID:22920095

    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.

    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 multiple etiologic factors involved in acne make the use of various medications necessary to treat the condition. This study aimed to determine the efficacy of mupirocin and rifampin used with standard treatment in the management of acne vulgaris. In a multicentre, randomized controlled, triple-blinded study, a total of 105 acne patients, with a clinical diagnosis of moderate to severe acne,were randomizedly divided into three groups (35 per group), for treatment of acne. The first group was treated with standard treatment alone, the second group received mupirocin plus standard treatment and the third group received rifampin plus standard treatment.There were three study visits according to Global Acne Grading System (GAGS): at baseline and weeks 6 and 12. The absolute changes of GAGS score from baseline to week 6 and 12 demonstrated a reduction in the mean score of GAGS in the three treatment groups (p < 0.001). Due to the difference between GAGS score at the baseline of study, the data were adjusted using the general linear model. The findings showed that all of the treatments significantly improved acne lesions. Nevertheless, none of the treatments was shown to be more effective than the others (p = 0.9). The three treatments were well tolerated, and no serious adverse events were reported. These findings provide evidence on the efficacy of combining mupirocin and rifampin with standard treatment in the management of acne vulgaris, although none of the treatments had superior efficacy compared with the others.

    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). PMID:16821451

    Background/purpose Conventional treatment methods for acne vulgaris have various side effects such as the development of bacterial resistance, phototoxicity, vertigo, gastro-intestinal problems, and drug eruptions. To minimize such side effects, light and thermal methods have been alternately suggested. This study characterized a new acne vulgaris treatment device (AVTD) that combines both light and thermal methods and evaluated its clinical efficacy. Methods We characterized the thermal and light properties of the AVTD itself and evaluated its thermal characteristics in ex vivo porcine skin samples. The Arrhenius equation was used to calculate the skin thermal injury coefficient to confirm the skin safety of the AVTD. Finally, the clinical efficacy of the AVDT was evaluated by analyzing cross-polarization and erythema index images, which were obtained from 13 volunteers undergoing treatment with the AVTD. Results The temperature of the AVTD itself was maintained at 49.1 °C on the tip and 39.7 °C in the porcine skin samples. The peak intensity of the light-emitting diode (LED) light was observed at 468 nm. The skin safety of the AVTD was confirmed and 84.2% of the volunteers presented positive treatment results. Conclusion The treatment of acne using the AVTD resulted in a high treatment rate in a clinical study, minimizing side effects. On the basis of these results, we can be sure that the AVTD may be effectively used for the treatment of acne vulgaris. PMID:21585558

    Despite acne being an almost universal condition in younger people, relatively little is known about its epidemiology. We sought to review what is known about the distribution and causes of acne by conducting a systematic review of relevant epidemiological studies. We searched Medline and Embase to the end of November 2011. The role of Propionibacterium acnes in pathogenesis is unclear: antibiotics have a direct antimicrobial as well as an anti-inflammatory effect. Moderate-to-severe acne affects around 20% of young people and severity correlates with pubertal maturity. Acne may be presenting at a younger age because of earlier puberty. It is unclear if ethnicity is truly associated with acne. Black individuals are more prone to postinflammatory hyperpigmentation and specific subtypes such as 'pomade acne'. Acne persists into the 20s and 30s in around 64% and 43% of individuals, respectively. The heritability of acne is almost 80% in first-degree relatives. Acne occurs earlier and is more severe in those with a positive family history. Suicidal ideation is more common in those with severe compared with mild acne. In the U.S.A., the cost of acne is over 3 billion dollars per year in terms of treatment and loss of productivity. A systematic review in 2005 found no clear evidence of dietary components increasing acne risk. One small randomized controlled trial showed that low glycaemic index (GI) diets can lower acne severity. A possible association between dairy food intake and acne requires closer scrutiny. Natural sunlight or poor hygiene are not associated. The association between smoking and acne is probably due to confounding. Validated core outcomes in future studies will help in combining future evidence. PMID:23210645

    Acne affects approximately 95% of the population at some point during their lifetime.1 This common disorder can range from mild to severe forms, cause sometimes extensive scarring, and can last well into the fourth and fifth decades. Effective therapeutic agents are available to both treat acne and prevent ongoing disease. Despite this, dermatologists frequently see patients with significant acne scarring because many patients delay seeking medical attention for acne and many practitioners procrastinate over using effective antiscarring options. In patients who already demonstrate scarring, repeated courses of antibiotics only result in recurring acne and additional scarring. This, in turn, exacerbates the despair and other adverse psychosocial effects of the disease. There are a variety of agents and devices to help acne patients with scarring. However, successful treatment cannot be guaranteed, and in most cases residual scarring will be evident. Thus, the most effective way of managing acne scarring is to prevent its occurrence in the first place. Although we currently have a number of effective antiacne agents to control the disease, such as antibiotics and hormonal agents, isotretinoina is the only agent that has been shown to induce long-term drug-free remission and curative potential.

    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

    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.

    Taurine bromamine (TauBr), the product of taurine and hypobromous acid (HOBr), exerts anti-inflammatory and antibacterial properties. Recently we have shown that Propionibacterium acnes, a potential pathogenic agent of acne, is extremely sensitive to TauBr. As topical antibiotics are associated with the emergence of resistant bacteria, TauBr seems to be a good candidate for topical therapy for acne vulgaris. In our double blind investigation, the efficacy and safety of 3.5 mM TauBr cream was evaluated. 1% Clindamycin gel (Clindacin T), one of the most common topical agents in the treatment of acne vulgaris, was used as a control. Forty patients with mild to moderate inflammatory facial acne vulgaris were randomly treated with either TauBr or clindamycin for 6 weeks, twice-a-day. More than 80% of the patients markedly improved with both treatments, without any adverse effects observed. Both TauBr and clindamycin produced a significant reduction in inflammatory skin lesion counts (papules/ pustules). After 6 weeks, comparable reductions of acne lesions, 65% and 68%, were observed in the TauBr and clindamycin groups, respectively. In conclusion, these data support our concept that TauBr can be used as a topical agent in the treatment of acne vulgaris, especially in patients who have already developed antibiotic resistance.

    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. PMID:18575221

    Introduction Numerous plant products described in the scientific literature show distinct activities on the skin, such as moisturizing, antioxidant, sunscreen, anti-acne and depigmentation. Aim The main objective of this study was to compare the effectiveness of emulsion formulations containing plant extracts (Hippophae rhamnoides and Cassia fistula) and placebo (without plant extracts) on acne patients. Material and methods A single-blind, randomized, placebo-controlled, split-face study was designed. Two groups of 25 patients each (aged 18–37 years) with grade I and grade II acne vulgaris received active formulations on the left side of their cheeks and placebo on the right side of their cheeks twice daily for 12 weeks. Prior to the study, signed consent was obtained from each patient. The anti-bacterial activity of the extracts and formulations was tested in vitro. The skin sebum contents of patients were evaluated by the sebumeter® and subjectively using a clinical evaluation before and after treatment of 12 weeks. One way ANOVA and Kruskal-Wallis tests were used in the statistical analysis. Results A significant (p ≤ 0.05) decrease in the level of sebum contents was observed in both groups who used formulations (F1 and F2) containing the plant extract. The difference between pre- and post-treatment levels of sebum contents was statistically significant (p ≤ 0.05). Formulations containing plant extracts were found effective in the reduction of skin sebum contents (anti-acne effects) sebumetrically as well as clinically when compared to placebo (F3). Conclusions Formulations with 5% plant extracts could be effective, safe, and well-tolerated topical medications for grade I and grade II acne vulgaris. PMID:25254008

    Acne vulgaris is a very common inflammatory skin disease originating from the pilosebaceous unit. Peak incidence is at puberty, but acne can affect all age groups. Prepubertal acne is rare, but important to recognize as diagnostic and therapeutic procedures differ from pubertal acne. Acne neonatorum is a mild, self-limiting disease, whereas acne infantum commonly presents with moderate to severe lesions and high risk of scarring thus requiring early intervention. Mid-childhood or prepubertal acne raises the suspicion of hyperandrogenemia, further investigations are indicated to rule out underlying disease. The same applies to any patient with very severe acne, acne not responding to therapy or unusual clinical presentation. Etiopathogenesis of acne is not yet fully understood. Familiy history is the most important risk factor to develop severe acne and scarring. The relevance of life style factors such as smoking or diet is controversial. Lately high carbohydrate diet and dairy products have been implicated as aggravating factors. Mild acne normally responds to topical monotherapy, in moderate disease combination of two synergistically acting substances (e.g. benzoyl peroxid plus antibiotic, benzoyl peroxid plus retinoid, retinoid plus antibiotic, benzoyl peroxid plus azelaic acid) will improve clinical response. Retinoids and/or benzoylperoxid have been shown to be effective in maintenance therapy. In patients with severe disease or high risk of scarring systemic therapy with antibiotics, oral contraceptives with antiandrogenic properties and in particularly isotretinoin as most effective acne treatment should be considered early to avoid physical and emotional scars.

    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.

    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.

    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. LMB-IPL is more effective than IPL alone, safe with tolerable pain in the treatment of acne vulgaris on the back. PMID:26993345

    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

    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).

    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. PMID:25594129

    Background Acne is a chronic skin disease characterised by inflamed spots and blackheads on the face, neck, back, and chest. Cysts and scarring can also occur, especially in more severe disease. People with acne often turn to complementary and alternative medicine (CAM), such as herbal medicine, acupuncture, and dietary modifications, because of their concerns about the adverse effects of conventional medicines. However, evidence for CAM therapies has not been systematically assessed. Objectives To assess the effects and safety of any complementary therapies in people with acne vulgaris. Search methods We searched the following databases from inception up to 22 January 2014: the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL; 2014, Issue 1), MEDLINE (from 1946), Embase (from 1974), PsycINFO (from 1806), AMED (from 1985), CINAHL (from 1981), Scopus (from 1966), and a number of other databases listed in the Methods section of the review. The Cochrane CAM Field Specialised Register was searched up to May 2014. We also searched five trials registers and checked the reference lists of articles for further references to relevant trials. Selection criteria We included parallel-group randomised controlled trials (or the first phase data of randomised cross-over trials) of any kind of CAM, compared with no treatment, placebo, or other active therapies, in people with a diagnosis of acne vulgaris. Data collection and analysis Three authors collected data from each included trial and evaluated the methodological quality independently. They resolved disagreements by discussion and, as needed, arbitration by another author. Main results We included 35 studies, with a total of 3227 participants. We evaluated the majority as having unclear risk of selection, attrition, reporting, detection, and other biases. Because of the clinical heterogeneity between trials and the incomplete data reporting, we could only include four

    Available for more than 5 decades, benzoyl peroxide has been a "workhorse" of acne therapy. 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. PMID:16673802

    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

    Acne vulgaris is considered as a therapeutic challenge in terms of managing ongoing symptoms and preventing scar formation. Although there are many available treatments for alleviating acne, therapies for resistant or moderate-to-severe forms have been limited to systemic agents that are accompanied by potentially severe side-effects. While, aminolevulinic acid (ALA) photodynamic therapy (PDT) has increasingly been used as a simple and safe therapeutic option of acne vulgaris, the clinical efficacy requires confirmation in further studies. The aim of this study was to investigate the efficacy and safety of 5-ALA-PDT in the treatment of moderate-to-severe facial acne vulgaris. A total of 50 patients with moderate-to-severe facial acne were enrolled in the study and randomly divided equally into a therapy group and a control group. In the therapy group, the patients were treated with 5% 5-ALA for 1.5 h, followed by three 20-min doses of infrared radiation once a week; in the control group, the patients were treated with three 20 min doses of infrared radiation without 5-ALA once a week. Both treatments lasted for 3 weeks. The clinical efficacy was determined by evaluating acne lesion counts at weeks 0, 2, 4 and 6. Total efficacy rate (TER) was the primary endpoint of the study, and was defined as the proportion of the patients whose treatment effectiveness evaluation was cured (≥90% of skin lesions improved) and excellent (60–89% improvement). Adverse effects were recorded throughout the study. The study was completed by 24 patients in the therapy group and 23 patients in the control group. The numbers of acne lesions significantly decreased. The TER of the therapy group was significantly higher than that of the control group at weeks 4 and 6. Adverse effects were observed in 12 patients of the therapy group and 2 patients of the control group. In the therapy group the most common adverse effect was a burning sensation (n=7), followed by transient

    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.

    In situations where acne has proved resistant to other systemic agents or they are not indicated and isotretinoin is not desired by patients, the authors find amoxicillin, TMP-SMX, and spironolactone, alone or in combination, useful alternatives. In women who have acne, spironolactone can be used, and in patients who have sulfa allergy, amoxicillin can be used. It is important to continue alternate topical therapy along with these interventions to augment the improvement and to assist in the eventual discontinuance of oral medication. All of the authors' patients were using topical therapy concomitantly and, although this may have contributed to improvement, the authors believe the addition of amoxicillin, TMP-SMX, or spironolactone contributes to the majority of improvement. Tetrospective chart analysis provides supportive data for amoxicillin, TMP-SMX, and spironolactone in the treatment of refractory acne vulgaris. PMID:18159900

    Background: Isotretinoin is indicated for moderate to severe cases of acne which are unresponsive to conventional therapy. The classical recommended dose is 0.5 to 1.0 mg/kg/day. As the side effects are dose related, low-dose isotretinoin therapy for acne is an attractive option; however, but little data exists on the safety and efficacy of this strategy. Materials and Methods: In this prospective, non-comparative study, 50 participants, both male and female, having moderate to severe acne vulgaris were enrolled and treated with isotretinoin at a dose of 20 mg/day (approximately 0.3-0.4 mg/kg/day), for a period of 3 months. Participants were evaluated by means of clinical and laboratory investigations before starting isotretinoin. Investigations were repeated at the end of the first and third months following completion of treatment, and participants were followed up for 6 months to look for any relapse. Results: At the end of the treatment, very good results were observed in 90% of participants. Cheilitis was the most common among the side effects observed and was seen in 98% of the participants. One participant developed vitiligo as a side effect, which is a new finding, and has not reported in literature before. Elevated serum lipid levels were observed in 6% of the participants, and relapse occurred in 4% of the participants over a 6 month follow up period. Conclusion: Three months of treatment with low-dose isotretinoin (20 mg/day) was found to be effective in the treatment of moderate to severe acne vulgaris, with a low incidence of serious side effects. This dose also was more economical than the higher doses. PMID:24891681

    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.

    Acne vulgaris is an epidemic inflammatory skin disease of multi-factorial origin, frequently seen in adolescents and often persisting or occurring through to adulthood. Acne vulgaris is a nearly universal skin disease afflicting 79-95% of the adolescent population in westernized societies and is a significant cause of psychological morbidity in affected patients. Despite the various treatment options available for acne, there is still a need for a safe and effective option. The aim of the study was to investigate the efficacy and tolerability of Dr Michaels® (Zitinex®) product family in the treatment of papulo-pustular acne. 25 patients (17 female/8 male), aged 15-22, with a mild to moderate papulo-pustular acne, localized on the face and on the trunk, were included in this study. None of the patients had used any other kind of treatment in the 3 months prior to commencing this study. All of the patients were treated with Dr Michaels® (Zitinex®) facial exfoliating cleanser, activator formula, a cream, PSC 200 and PSC 900 oral supplements. Application time of Dr Michaels® (Zitinex®) products was 12 weeks. The treatment was been evaluated clinically at 0, 4, 8 and 12 weeks. All of the patients showed an improvement in all parameters of their acne (comedones, papules, pustules, hyperpigmentation and scars). The acne lesions and erythema had mostly resolved. The hyperpigmentation and pitted scarring had significantly reduced also, with the skin appearing smoother. The treatment was well tolerated and no side effects have been described. Our study demonstrates that the Dr Michaels® (Zitinex®) facial exfoliating cleanser, activator formula, cream and oral supplements PSC 200 and PSC 900 are an effective therapeutic option for the treatment of moderately severe acne vulgaris. Moreover, it highlights the safety profile of the Dr Michaels® (Zitinex®) product family in a case of acne compared to traditional first-line treatments. PMID:27498658

    Background: Acne vulgaris is considered one of the most common disorders for which patients seek dermatologic care. In the current study, we evaluated efficacy of the 5% nicotinamide gel versus 2% clindamycin gel in the treatment of the mild-moderate acne vulgaris. Materials and Methods: This was a randomized, controlled clinical trial that was performed in 2009-2010. Sixty female patients with mild or moderate acne vulgaris were recurited to be treated either with 5% nicotinamide or 2% clindamycin gel for 8 weeks. Acne severity index (ASI) was used to evaluate response to treatment and SPSS software was used to analyze the data. Results: The mean of ASI at the baseline was 16.85 ± 8.5 and 18.2 ± 12.27 in nicotinamide gel and clindamycin gel, respectively (P > 0.05). The mean of ASI was significantly decreased compared with baseline ASI during the time in both groups (P < 0.0001). However, there was not a significant difference regarding reduction of ASI between the nicotinamide and clindamycin gel (P = 0.583). Conclusion: Five percent nicotinamide gel is as effective as 2% clindamycin gel for treatment of mild to moderate acne vulgaris. No side effect was observed during the treatment. PMID:23914212

    Efficacy and safety of azithromycin and doxycycline for the treatment of moderate acne vulgaris were evaluated (240 patients) in both intention-to-treat and per-protocol populations. The evaluation of clinical efficacy was based on the change in the number of facial inflammatory lesions from baseline to the end of treatment, and noninferiority was defined by the upper 95% confidence limit of the difference between two treatments being less than 9. Reduction in the number of lesions was similar with both azithromycin and doxycycline treatments (27 +/- 12 and 30 +/- 12, respectively) in both groups. Also, the upper 95% confidence limit of 5 inflammatory lesions has satisfied the noninferiority criterion. The incidence of adverse events did not differ between the two treatment groups. The shorter and simpler treatment schedule of azithromycin had similar efficacy and safety as doxycycline in the treatment of moderate acne vulgaris, confirming noninferiority of azithromycin as compared with doxycycline.

    PubMed

    Del Rosso, James Q

    2016-06-01

    Antibiotics, both oral and topical, have been an integral component of the management of acne vulgaris (AV) for approximately 6 decades. Originally thought to be effective for AV due to their ability to inhibit proliferation of Propionibacterium acnes, it is now believed that at least some antibiotics also exert anti-inflammatory effects that provide additional therapeutic benefit. To add, an increase in strains of P acnes and other exposed bacteria that are less sensitive to antibiotics used to treat AV have emerged, with resistance directly correlated geographically with the magnitude of antibiotic use. Although antibiotics still remain part of the therapeutic armamentarium for AV treatment, current recommendations support the following when used to treat AV: 1) monotherapy use should be avoided; 2) use benzoyl peroxide concomitantly to reduce emergence of resistant P acnes strains; 3) oral antibiotics should be used in combination with a topical regimen for moderate-to-severe inflammatory AV; and 4) use oral antibiotics over a limited duration to achieve control of inflammatory AV with an exit plan in place to discontinue their use as soon as possible. When selecting an oral antibiotic to treat AV, potential adverse effects are important to consider. PMID:27416309

    Introduction Laser and light-based procedures provide a good and safe modality for treatment of active acne lesions when used properly. Aim To compare the clinical efficacy of intense pulsed light (IPL) versus 1,064 long-pulsed Neodymium:Yttrium–Aluminum– Garnet (Nd: YAG) in treatment of facial acne vulgaris. Materials and Methods Seventy four patients recruited between June 2013 and August 2014 was enrolled in this controlled, single-blind, split-face clinical trial. All participants received 3 sessions of IPL on the right side of the face and 1,064-nm Nd:YAG on the left side of the face at 4-weeks intervals. Final assessment was made by comparison of the changes in the count of inflammatory acne lesions (inflammatory papules, pustules, nodules and cyst) and non-inflammatory acne lesions (Comedones) and the acne severity score between both therapies, based on standardized photography. Results At the final visit, the inflammatory acne lesions were reduced on the IPL and 1,064-nm Nd:YAG treated sides by 67.1% and 70.2% respectively (p<0.05 for each), while non inflammatory acne lesions were reduced by 18.3% and 19.3% respectively (p>0.05 for each). For both therapies, there was significant difference in the improvement on inflammatory acne lesions in comparison to non-inflammatory lesions (p<0.05 for each). There was no significant difference in the efficacy of the two therapies in reducing the percentage of both types of acne lesions count from baseline to the end of the study (p>0.05 for each). Conclusion Both IPL and 1,064-nm Nd:YAG laser are effective in treatment of inflammatory facial acne vulgaris. There is no significant difference between the effects of both therapies on facial acne lesions.

    Few long-term treatment regimens for severe acne vulgaris have been investigated in clinical trials. Data were combined from two consecutive, randomized, double-blind, controlled studies to evaluate the efficacy, safety and subject satisfaction of four nine-month regimens in severe acne vulgaris treatment. Subjects were first randomized to receive doxycycline (DCN) and adapalene 0.1% - benzoyl peroxide 2.5% (A/BPO) or vehicle once daily for 12 weeks. Subjects who had at least 50% global improvement were subsequently randomized to receive A/BPO or its vehicle once daily for 24 weeks. Over nine months, there were four regimens: A/BPO and DCN followed by A/BPO, vehicle and DCN followed by A/BPO, A/BPO and DCN followed by vehicle, and vehicle and DCN followed by vehicle. Among the four regimens, A/BPO and DCN followed by A/BPO led to the highest percentage of subjects rated "clear" or "almost clear" (50.0% vs. 40.4%, 26.2% and 25.0%, respectively), biggest reduction in total lesion counts (76% vs. 70%, 51% and 47%, respectively) and greatest subject satisfaction (85.0% vs. 75.5%, 63.3% and 52.4%, respectively) at week 36. It provided a faster onset of action compared to groups started with vehicle and DCN (P<.05 at week 2). Subjects receiving A/BPO and DCN followed by vehicle experienced deterioration once the active treatment was discontinued. All regimens were safe and well-tolerated. In conclusion, efficacious initial therapy and long-term treatment are both important. An initial combination therapy with adapalene-BPO and DCN followed by longer-term adapalene-BPO treatment is an efficacious and satisfactory new regimen for severe acne subjects. PMID:22270198

    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

    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

    The efficacy of combined therapy with a retinoid and antibiotic for Japanese patients with acne vulgaris remains to be established. Further, maintenance strategies limiting the use of topical retinoids must be identified. The objectives of this study are to determine the efficacy of sequential application of topical adapalene and clindamycin phosphate and to assess the impact of this regimen on patients' quality of life. Sixty-six patients were recruited. The regimen comprised two phases. For the 4-week initial treatment, 1% clindamycin phosphate gel was applied twice daily and 0.1% adapalene gel, once. In the 4-week maintenance phase, patients were randomly assigned to the OD group (adapalene applied once daily) or the TW group (adapalene applied once daily on 2 days per week). The acne severity score, lesion counts, microcomedone count, and sebum amount were measured. Quality of life (QOL) was assessed using Skindex-16. All parameters improved significantly by week 4 of initial treatment. No statistically significant differences were found in the improvement of clinical findings between the groups. All QOL scores improved significantly and did not significantly differ between the groups. Our regimen may enable clinical control of acne in Japanese patients and improve their QOL. For limiting retinoid use, weekly application of adapalene during maintenance is suitable. PMID:21254867

    Background An antibiotic-free, fixed-dose combination gel with adapalene (A) 0.1% and benzoyl peroxide (BPO) 2.5% has been developed for treatment of acne vulgaris. Objective To compare the clinical outcomes of A-BPO combination gel with vehicle gel for treatment or maintenance therapy of patients with acne vulgaris. Methods An electronic search of the database PubMed (1966 to September 2012), Embase (1984 to September 2012), and Cochrane Controlled Trials Register (CENTRAL; 3rd Quarter, 2012) was undertaken to identify relevant studies. Main clinical outcomes were success rate, treatment-related adverse events (AEs), AEs leading to discontinuation, satisfaction with the effectiveness, and overall satisfaction. Results Six studies were finally included in this meta-analysis. The A-BPO group yielded better clinical outcomes regarding the success rate (p<0.00001), satisfaction with the effectiveness of treatment (p=0.005), and overall satisfaction (p=0.005) compared to the vehicle group. The incidence of treatment-related AEs in the A-BPO group was comparable with that of vehicle group (p=0.09), while the A-BPO group was associated with a slightly increase in the incidence of AEs leading to discontinuation when compared with the vehicle group (p=0.02). Conclusion A-BPO combination gel yields better clinical outcomes including success rate, satisfaction with the effectiveness, and overall satisfaction compared to vehicle gel, despite an increased incidence of AEs leading to discontinuation. The A-BPO combination agent most likely contributes to the treatment of moderate acne vulgaris rather than severe acne vulgaris, but it may be useful in maintenance therapy of patients with severe acne vulgaris.

    Background: The efficacy of isotretinoin at 0.5 to 1.0 mg/kg per day in the treatment of acne is well established and considered safe, although it is sometimes not easily tolerated because of its cutaneous side effects. Objective: The purpose of this study was to determine the efficacy of low-dose isotretinoin in the treatment of acne. Methods: In this prospective, non comparative, open-label study, 50 patients, both male and female, with moderate acne were enrolled and treated with isotretinoin at 20 mg/d (approximately 0.3-0.4 mg/kg per day) for 3 months. The patients were divided into two age groups: 12 to 20 and 21 to 35 years old. Patients were evaluated at 2-month intervals by means of clinical and laboratory examinations. A 4-year follow-up was also carried out. Results: At the end of the treatment phase, good results were observed in 90.8% of the patients aged 12 to 20 years, and in 89.6% of the patients aged 21 to 35 years. Failure of the treatment occurred in 5.2% and 7.4% of the two groups, respectively. Three patients dropped out of the study because of lack of compliance, and another patient discontinued participation because of a laboratory side effect. During the 2-year follow-up period, relapses of the acne occurred in 3.9% of the patients aged 12 to 20 years and in 5.9% of the patients aged 21 to 35 years. Elevated serum lipid levels (up to 20% higher than the upper limit of normal value) were found in 4.2% of the patients and abnormal (treatment with low-dose isotretinoin (20 mg/d) was found to be effective in the treatment of moderate acne, with a low incidence of severe side effects and at a lower cost than higher doses.

    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

    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

    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

    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.

    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.

    Topical retinoids, benzoyl peroxide, azelaic acid, and topical and oral antibiotics remain the milestone of treatment for mild to moderate acne vulgaris. Oral isotretinoin is useful for the treatment of severe nodular acne, treatment-resistant acne, and acne with a risk of physical or psychological scarring. Hormonal treatment in female acne is useful in resistant or late-onset acne. With increasing concerns regarding teratogenicity of isotretinoin and increasing antibiotic resistance, there is a clear need for therapeutic alternatives to these long-used treatments. Research in the pathogenesis of acne has allowed for new therapies and future perspectives regarding acne to evolve. They include low-dose long-term isotretinoin regimens, insulin-sensitizing agents, 5alpha-reductase type 1 inhibitors, topical photodynamic therapy, new combination formulations, dietary interventions, and antiinflammatory agents such as lipoxygenase inhibitors.

    A designed peptide named LZ1 with 15 amino acid residues containing strong antimicrobial activity against bacteria pathogens of acne vulgaris including Propionibacterium acnes, Staphylococcus epidermidis and S. aureus. Especially, it exerted strong anti-P. acnes ability. The minimal inhibitory concentration against three strains of P. acnes was only 0.6 µg/ml, which is 4 times lower than that of clindamycin. In experimental mice skin colonization model, LZ1 significantly reduced the number of P. acnes colonized on the ear, P. acnes-induced ear swelling, and inflammatory cell infiltration. It ameliorated inflammation induced by P. acnes by inhibiting the secretion of inflammatory factors including tumor necrosis factor-α (TNF-α) and interleukin (IL)-1β. LZ1 showed little cytotoxicity on human keratinocyte and hemolytic activity on human blood red cells. Furthermore, LZ1 was very stable in human plasma. Combined with its potential bactericidal and anti-inflammatory properties, simple structure and high stability, LZ1 might be an ideal candidate for the treatment of acne. PMID:24013774

    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

    Background Acne vulgaris is a distressing condition that affects the majority of adolescents, but the impact of acne vulgaris on the psychological aspects in this age group is poorly understood. Objective The purpose of this study was to determine the prevalence of acne, and the level of emotional, social, and functional impairments among Korean adolescents with acne. Methods Five hundred four middle school students (13~16 years) participated. The severity of acne was graded by visual examination using the Korean Acne Grading System. Self-reported questionnaires, including subjective acne severity rating, the Self Image Questionnaire, the Rosenberg Self-Esteem Questionnaire, the Index of Peer Relations, and the Beck Depression Inventory were used to assess psychologic status. Results There was a prevalence of acne in 78.9% of the study samples, with 10.2% of students having moderate-to-severe acne. Acne was more prevalent and severe in boys than girls. Participants with severe acne and girls had higher levels of emotional and social impairments. The longer the acne persisted, the more stress the students felt. The degree of stress and extent of self-image impairment were related to subjective severity more than objective grading. Conclusion Acne is a common disorder among Korean adolescents and appears to have a considerable impact on mental health. Dermatologists should be aware of the importance of basic psychosomatic treatment in conjunction with early medical, educational intervention in the management of acne. PMID:20523769

    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

    The Global Alliance to Improve Outcomes in Acne Group recommends retinoid-based combination therapy as first-line therapy and the preferred treatment approach for almost all acne patients except those with the most severe disease. Clindamycin 1% (as clindamycin phosphate 1.2%)/tretinoin 0.025% (Clin-RA) is a new fixed-dose retinoid-based combination therapy. The aqueous-based gel formulation of Clin-RA was designed to minimize skin irritation and optimize adherence with the therapy. It contains both solubilized and crystalline tretinoin which allows the retinoid to be slowly released onto the skin surface and decreases the potential for cutaneous irritation. A pooled analysis of three pivotal studies involving 4550 acne patients showed that Clin-RA is well tolerated and effective at treating both inflammatory and non-inflammatory acne lesions. The onset of action of Clin-RA is rapid occurring within 2 weeks of treatment initiation. It is not associated with acne flaring or an increase in clindamycin-resistant Propionibacterium acnes counts. Clin-RA is considered as effective as adapalene 0.1%/benzoyl peroxide (BPO) 2.5%, whereas Clin-RA has a more favourable tolerability profile. Clin-RA may be more effective than clindamycin 1%/BPO 5% at treating non-inflammatory acne lesions since the latter does not contain a retinoid to target comedones. Clin-RA is also easy for patients to handle and apply, and has the advantage of not containing BPO which can bleach hair and fabrics. Taken together, the profile of Clin-RA suggests Clin-RA to be a first-line treatment for patients with facial acne. PMID:26059820

    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. PMID:26957383

    Desmosomes contribute towards adhesion between adjacent keratinocytes. In acne vulgaris, increased intercellular adhesion is thought to contribute to the retention of keratinocytes within the follicular lumen during comedogenesis. Therefore, the distribution of different desmosomal components was investigated in normal and acne subjects. Biopsies were cryostat-sectioned (6 microns), and stained with antibodies to different desmosomal components: desmoplakin 1/2, desmoglein 1, desmocollin 3a/3b, and a late desmosomal antigen, G36-19. Desmoplakin 1/2, desmoglein 1 and desmocollin 3a/3b shared a similar distribution in follicles from control skin, from acne-affected skin, and in non-inflamed lesions. All three proteins were expressed around the periphery of keratinocytes of all the intrafollicular epidermis, except the basal lamina and the upper stratum corneum. In inflamed lesions, the expression of desmoglein 1 and desmocollin 3a/3b was diminished; in 12.5%, staining for these two proteins was completely abolished, and in 81.25% of the lesions investigated the staining was patchy. The antibody G36-19 bound to an antigen in the upper granular layer in the infundibular epidermis. No differences were noted in the staining pattern of the follicular epithelia of controls, non-inflamed, and inflamed lesions. This study, using monoclonal antibodies, did not identify any changes in the desmosomal components which might explain the increased adhesion between follicular keratinocytes during comedogenesis.

    Objective To assess relationship between alexithymia and acne vulgaris in young people. Methods A hundred and eleven subjects between 15 and 25 years of age referred to out-patient clinic of dermatology with acne and 78 subjects applied to family physician for complaints other than acne were included in patient and control groups of the study, respectively. A questionnaire to determine demographic characteristics, an acne classification to determine severity of acne and Toronto Alexithymic Scale (TAS) to assess alexithymia were used. Results The mean scores of TAS were 52.7±10.8 and 51.7±10.7 in patient and control groups, respectively. Alexitymia was determined in 23.4% of the subjects in acne group and in 24.4% of control group. No significant differences were found between groups in terms of alexithymia, intermediate alexitymia and three-factors of TAS. Conclusion Alexithymia does not appear to be related to acne vulgaris.

    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

    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.

    Background: Acne vulgaris is commonplace and can be difficult to manage. Providing an effective and well-tolerated treatment may lead to improved adherence, increased patient satisfaction, and improved clinical outcomes. Methods: A review of efficacy, safety, and cutaneous tolerability of clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel in 498 patients with moderate-to-severe acne vulgaris enrolled in a multicenter Phase III study randomized to receive active or vehicle once daily for 12 weeks, including the most recent post-hoc analyses. Results: Significantly superior reductions in lesion counts were observed with clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel from Week 4, with median percent reductions in inflammatory and noninflammatory lesions from baseline of 68.4 and 57.9 percent, respectively (bothp<0.001 versus vehicle). More than half (55.1%) of the severe acne vulgaris patients treated with clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel achieved ≥2-grade improvement from baseline in their Evaluator’s Global Severity Score, and almost a third of the adolescent acne vulgaris patients (32.4%) achieved at least a marked improvement in their acne vulgaris as early as Week 2. In adult female acne overall treatments success was achieved in 52.7 percent of patients treated with clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel. Overall, and in the specific subpopulations, clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel was well-tolerated with a similar adverse event profile to vehicle. Limitations: Post-hoc analyses from a single clinical trial with demographic imbalances that could potentially confound the results. Conclusion: Clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel appears to be effective in treating acne across various clinically relevant sub-groups. PMID:26705445

    Propionibacterium acnes (P. acnes) bacteria play a key role in the pathogenesis of acne vulgaris. Although our previous studies have demonstrated that vaccines targeting a surface sialidase or bacterial particles exhibit a preventive effect against P. acnes, the lack of therapeutic activities and incapability of neutralizing secretory virulence factors motivate us to generate novel immunotherapeutics. In this study, we develop an immunotherapeutic antibody to secretory Christie-Atkins-Munch-Peterson (CAMP) factor of P. acnes. Via agroinfiltration, P. acnes CAMP factor was encapsulated into the leaves of radishes. ICR mice intranasally immunized with whole leaves expressing CAMP factor successfully produced neutralizing antibodies that efficiently attenuated P. acnes-induced ear swelling and production of macrophage-inflammatory protein-2. Passive neutralization of CAMP factor enhanced immunity to eradicate P. acnes at the infection site without influencing bacterial growth elsewhere. We propose that CAMP factor is a novel therapeutic target for the treatment of various P. acnes-associated diseases and highlight the concept of neutralizing P. acnes virulence without disturbing the bacterial commensalism in human micorbiome.

    Acne vulgaris is a distressing skin condition which can carry with it significant psychological disability. Patients with acne are more likely to experience anger and are at increased risk of depression, anxiety, suicidal ideation. Certain nutrients which have been implicated as influencing the pathophysiology of acne have also been identified as important mediators of human cognition, behavior and emotions. Zinc, folic acid, selenium, chromium and omega-3 fatty acids are all examples of nutrients which have been shown to influence depression, anger and/or anxiety. These same nutrients, along with systemic oxidative stress and an altered intestinal microflora have been implicated in acne vulgaris. It is our contention that certain nutritional factors, a weakened antioxidant defense system and altered intestinal microflora may interplay to increase the risk of psychological sequelae in acne vulgaris.

    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. PMID:27015780

    2015-01-01

    Objective: To determine whether the response to dapsone 5% gel was similar in adolescent girls and adult women with facial acne vulgaris. Design and setting: Subgroup analysis of female subjects with acne vulgaris receiving active treatment enrolled in two randomized, double-blind Phase 3 clinical trials. Treatment: Twice-daily applications of dapsone 5% gel over 12 weeks. Participants: Adolescent (12-17 years of age) and adult (≥18 years of age) females. Measurements: At baseline and at Weeks 2,4,6,8, and 12, subjects were evaluated using the global acne assessment score and by counts of inflammatory, noninflammatory, and total acne vulgaris lesions. Adverse events were monitored. Results: A total of 347 adolescent and 434 adult women were included in the subgroup analysis. At Week 12, dapsone 5% gel significantly reduced mean global acne assessment score in both subgroups (p<0.001); however, the proportion of subjects with clinical success (no or minimal acne based on global acne assessment score) at Week 12 was greater in adult women (53.5%) versus adolescent females (45.3%, p=0.022). Significantly greater percentage reductions in both noninflammatory (p<0.0001) and total lesion counts (p=0.0008) were observed in the adult group as compared to the adolescent group. Percentage reductions from baseline in inflammatory lesions were similar in both groups. No major safety issues and no previously unrecognized safety signals were noted. Conclusion: This subgroup analysis of female patients indicates that dapsone 5% gel twice daily is effective in reducing inflammatory and noninflammatory acne vulgaris lesions in both adolescent and adult women, and is safe in these subgroups. Overall, these data suggest that efficacy of dapsone 5% gel twice daily for facial acne vulgaris may be greater in the adult female population. PMID:25610522

    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 is a common inflammatory skin disease which affects the pilosebaceous units of the skin. It can have severe psychological effects and can leave the patient with severe skin scarring. There are four well-recognized pathological factors responsible for acne which is also the target for acne therapy. In this review, different treatment options are discussed, including topical (i.e., retinoids, and antibiotics) and systemic (i.e., retinoids, antibiotics, and hormonal) treatments. Since the general public has been showing an increasing interest in more natural and generally safer treatment options, the use of complementary and alternative medicines (CAM) for treating acne was also discussed. The use of physical therapies such as comedone extraction, cryoslush therapy, cryotherapy, electrocauterization, intralesional corticosteroids and optical treatments are also mentioned. Acne has been extensively researched with regards to the disease mechanism as well as treatment options. However, due to the increasing resistance of Propionibacterium acnes towards the available antibiotics, there is a need for new treatment methods. Additionally, the lack of necessary evidence on the efficacy of CAM therapies makes it necessary for researchers to investigate these treatment options further. PMID:27529209

    Acne scarring is common but surprisingly difficult to treat. Scars can involve textural change in the superficial and deep dermis, and can also be associated with erythema, and less often, pigmentary change. In general, treatment of acne scarring is a multistep procedure. First, examination of the patient is necessary to classify the subtypes of scarring that are present. Then, the patient's primary concerns are elicited, and the patient is offered a menu of procedures that may address the various components of the scarring process. It is important to emphasize to the patient that acne scarring can be improved but never entirely reversed. PMID:17180246

    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. PMID:27248464

    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. PMID:25157359

    Acne vulgaris is a chronic condition affecting more than 85% of adolescents and young adults. It is one of the most common diseases affecting humanity and its impact on quality of life (QoL) is important. The impact of acne on QoL in Indian patients remains undocumented. The study was undertaken to detect the impact of acne vulgaris and related factors that may influence the QoL. Materials and Methods: This was a hospital-based, prospective, cross-sectional, prestructured, questionnaire-based study done on 140 consenting individuals, who attended the Dermatology outpatient department. Acne vulgaris was graded using simple grading system. QoL was measured using a combination of skin disease-specific (Dermatological Life Quality Index (DLQI)) and acne-specific (Cardiff Acne Disability Index (CADI)) questionnaires. Results: Majority of our study population were students (103, 73.6%). Face (139, 99.3%) was the commonest site of acne and comedones 133, 95% were the commonest type of lesion. Most of the individuals 66, 47.1% were observed to have grade 1 acne. The mean DLQI score was 6.91 and the mean CADI score was 5.2. Association between the scores was statistically significant. Age, occupation, marital status, family, and treatment history played a role in affecting the QoL. Diet, smoking, and alcohol did not influence the QoL. Conclusion: Though acne had impact on patient's QoL, it was less severe in our study. It is important for health professionals to incorporate QoL measurements when managing acne patients to provide better and appropriate care. PMID:25657394

    2005-01-01

    Acne vulgaris is a common disorder that affects 40-50 million people in the USA alone. The pathogenesis of acne is multifactorial, including hormonal, microbiological and immunological mechanisms. One of the factors that contributes to the pathogenesis of acne is Propionibacterium acnes; yet, the molecular mechanism by which P. acnes induces inflammation is not known. Recent studies have demonstrated that microbial agents trigger cytokine responses via Toll-like receptors (TLRs). TLRs are pattern recognition receptors that recognize pathogen-associated molecular patterns conserved among microorganisms and elicit immune responses. We investigated whether TLR2 mediates P. acnes-induced cytokine production in acne. Using transfectant cells we found that TLR2 was sufficient for NF-kappaB activation in response to P. acnes. In addition, peritoneal macrophages from wild-type, TLR6 knockout and TLR1 knockout mice, but not TLR2 knockout mice, produced IL-6 in response to P. acnes.P. acnes induced activation of IL-12 and IL-8 production by primary human monocytes, and this cytokine production was inhibited by anti-TLR2-blocking antibody. Finally, in acne lesions, TLR2 was expressed on the cell surface of macrophages surrounding pilosebaceous follicles. These data suggest that P. acnes triggers inflammatory cytokine responses in acne by activation of TLR2. As such, TLR2 may provide a novel target for the treatment of this common skin disease.

    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.

    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. PMID:12053795

    Inflammation plays an important role in acne pathogenesis, and pro-inflammatory cytokines are key factors in these events. Tumor necrosis factor alpha (TNFα) is a central molecule coded by a gene that shows high level of genetic polymorphisms especially in its promoter region. Single nucleotide polymorphisms (SNPs) of the TNFα gene have been shown to be associated with an increased risk to develop chronic inflammatory diseases. In order to find out if known TNFα regulatory SNPs (-1031T>C, -857C>T, -863C>A, -308G>A, -238G>A) have a role in the development of the inflammatory reactions in acne vulgaris, we analyzed our genomic collection in a retrospective case-control study using the PCR-RFLP method, and we compared the resulting genotype and allele frequencies. There were no significant differences in the observed genotype or allele frequencies between the control and acne group in case of the -1031, -863, -238 SNPs; however, the TNFα -857 minor T allele was found to act as a protective factor in our study population in acne, and a higher occurrence of the minor -308 A allele in female acne patients was also noted. Genetic variants of the TNFα gene may affect the risk of acne vulgaris. Our results can help to elucidate the molecular events leading to acne development. PMID:20386917

    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.

    Skin care products are recognized by dermatologists as critical adjunctive therapeutic modalities for patients suffering from acne vulgaris (AV). Prescribing an acne medication without reviewing a patient's skin care regimen can lead to poor compliance, intolerable side effects, and resulting patient and physician frustration. Striking that delicate balance between maintaining the skin barrier while controlling oil and shine has always been a challenge when treating this chronic inflammatory condition, and it necessitates a unique set of ingredients and formulation. Cetaphil® DermaControl™ Moisturizer SPF 30 (Galderma Laboratories, L.P., Fort Worth, Texas) is a new generation of skin care specifically designed for acne-prone skin and acne-affected skin. Both Cetaphil® DermaControl™ Foam Wash and Cetaphil DermaControl Moisturizer SPF 30 incorporate pharmacologically tested, state-of-the-art ingredients and technologies that studies have shown impart substantial benefits to AV patients.

    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

  17. Clinical implications of lipid peroxidation in acne vulgaris: old wine in new bottles

    PubMed Central

    2010-01-01

    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. PMID:21143923

    Psychosocial outcome measures, which attempt to examine acne from the patient's perspective, have become increasingly important in dermatology research. One such measure is the Body Image Disturbance Questionnaire. The authors' primary aim was to determine the validity and internal consistency of the Body Image Disturbance Questionnaire in patients with acne vulgaris. The secondary aim was to investigate the relationship between body image disturbance and quality of life. This cross-sectional investigation included 52 consecutive acne patients presenting to an outpatient dermatology clinic. Subjects completed the Body Image Disturbance Questionnaire, Skindex-16, and other body image and psychosocial functioning measures. An objective assessment of acne was performed. The Body Image Disturbance Questionnaire was internally consistent and converged with other known body image indices. Body Image Disturbance Questionnaire scores also correlated with Skindex-16 scores, confirming that quality of life and body image are related psychosocial constructs. The Body Image Disturbance Questionnaire appears to be an accurate instrument that can assess appearance-related concern and impairment in patients with acne vulgaris. Limitations include a small sample size and the cross-sectional design. PMID:21779418

    The adverse effects of acne on the psyche have been established in patients from 'first world' countries. There has been no in depth study in predominantly black patients from Africa addressing this issue. This was a prospective cross-sectional study of acne patients attending a dermatology unit in KwaZulu-Natal, South Africa. A questionnaire was completed and acne graded by the Global Acne Grading scale. Psychological morbidity and quality of life (QOL) were assessed by the General Health Questionnaire and Dermatology Specific Quality of Life Questionnaires, respectively. We found that clinical severity was not associated with patient perception or psychological distress. The QOL measures such as feelings, social activities, performance at work or school, activities of daily living and overall mental health were found to be associated with distress with associated P-values of 0.0002, 0.0168, 0.0032, 0.033 and < 0.0001, respectively. The severity of acne was not associated with psychological distress. Painful and bleeding lesions were associated with distress levels; P = 0.042 and P = 0.019, respectively. In conclusion, South African patients with acne vulgaris suffer significant psychological distress, which affects the quality of their lives. PMID:15663491

    Berberis vulgaris L. (barberry) is a very well-known herb in traditional medicine. Apart from its anti-inflammatory and antibacterial properties, the antilipogenic effect of barberry on the sebaceous glands in animals may further suggest it could be employed as an anti-acne agent. This study examined the effect of oral aqueous extract of barberry on acne vulgaris. Adolescents aged 12-17 years with moderate to severe acne vulgaris were randomly given oral gelatin capsules containing either aqueous extract of dried barberry (600 mg daily for 4 weeks, n = 25) or placebo (n = 24). Counts of facial noninflamed, inflamed, and total acne lesions, as well as the Michaelson's acne severity score were documented at baseline and at weeks 2 and 4. Both groups were comparable in terms of the patients' characteristics and baseline variables. After 4 weeks, the mean number of noninflamed, inflamed, and total lesions as well as mean Michaelson's acne severity score declined significantly by 43.25 ± 10.88% (median: 42.11%), 44.53 ± 11.78% (median: 45.45%), 44.64 ± 8.46% (median: 46.15%), and 44.38 ± 8.25% (median: 44.07%), respectively, among the extract receivers (p <.001 for all the changes). Similar changes were not significant in the placebo group. No notable complication or side effect was reported in relation to barberry. In conclusion, oral aqueous extract of dried barberry is a safe, well-tolerated, and effective choice in teenagers with moderate to severe acne vulgaris. PMID:23038982

    Acne vulgaris suppresses an individual's self-confidence by causing distress with regard to physical appearance, which affects a significant number of individuals during puberty and is delineated by adolescence. Several treatments have been introduced to decrease the aesthetic and psychological problems caused by acne. The topical application of therapeutic agents has been found to be more feasible than hormonal treatment and laser therapy. The ingredients in topical acne treatments, particularly herbs and naturally derived compounds, have received considerable interest as they have fewer adverse effects than synthetic agents.

    Acne treatment regimens have changed due to the recent over-the-counter (OTC) switch of all prescription benzoyl peroxide (BPO) topical preparations. The elimination of prescription single-agent BPO products means that dermatologists must select from a variety of OTC formulations to utilize the time-tested efficacy of BPO in the treatment of mild to moderate acne. Our research compared the efficacy and safety of an OTC BPO 5.5% formulation with lipohydroxy acid and tretinoin cream 0.025% with prescription clindamycin 1%-BPO 5% gel and tretinoin cream 0.025%. Parity was demonstrated between the 2 treatment regimens at 12 weeks. PMID:22838094

    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.

    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

    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

    BACKGROUND Acne vulgaris can severely affect social and psychological functioning. OBJECTIVE The aim of this study was to investigate the impact of acne vulgaris and its severity on Quality of Life of young adolescents in Greece. METHODS We conducted a questionnaire based survey among 1560 adolescent between the ages of 11 and 19 years old and 1531 of these were completed. Adolescents with acne filled all the questions including the Children Dermatology Life Quality Index. Adolescents without acne filled the questions about age, family history of acne, stress and smoking. Data were analyzed with Pearson Chi Square test. RESULTS Acne prevalence was 51.2% affecting both sexes equally. Self reported mild acne was present in 71.2% and moderate-severe acne in 28.8% of the study population. The mean age of the study population was 15.77y. The median score of Children Dermatology Life Quality Index was 4.02. The impact of acne on quality of life is associated with the severity of the acne (p<0.0001). Patients with moderate/severe acne experience greater psychosocial and emotional impairment (p<0.0001). Body image is modified proportionally to the severity of acne (p<0.0001). Symptoms and treatment of acne are factors that also influence their quality of life. Girls and boys are equally affected. Stress and heredity are correlated with acne and its severity (p<0.0001). We didn't find any correlation between smoking and acne. CONCLUSION Acne affects Quality of Life of young adolescents in Greece. The impact is proportional to the severity of acne. More severe acne is associated with greater effect on quality of life with implications for self esteem, body image and relationships with others. PMID:23197205

    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. PMID:26211507

    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

    Acne is a common chronic inflammatory disease and treatment modalities based on acne severity are well established. The role of dermocosmetics in dermatology, and in particular acne, is becoming more important as more research elucidates the mechanisms of action of products in the pathogenesis of acne. Dermocosmetics have the potential to be used as monotherapy or in combination with medical treatment. Therefore, it has become important for dermatologists to understand dermocosmetics to effectively and appropriately advise patients on their use. The objective of this review was to provide new insights into the role of traditional and novel ingredients in dermocosmetics for the treatment of acne, based on the authors' objective assessment of the published literature. The type of products discussed include: those which have a sebostatic effect, such as topical antioxidants and niacinamide; agents targeting abnormal keratinization, such as salicylic acid, lipo-hydroxy acid, alpha-hydroxy acids, retinol-based products and linoleic acid; agents targeting Propionibacterium acnes, such as lauric acid; and anti-inflammatory agents such as nicotinamide, alpha-linolenic acid and zinc salts. Despite the scientific advances in understanding these cosmetic ingredients, there still remains a lack of rigorous controlled studies in this area. PMID:26916232

    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

Methodology/Principal Findings We have demonstrated in the present study that the Christie, Atkins, Munch-Peterson (CAMP) factor of P. acnes is a secretory protein with co-hemolytic activity with sphingomyelinase that can confer cytotoxicity to HaCaT keratinocytes and RAW264.7 macrophages. The CAMP factor from bacteria and acid sphingomyelinase (ASMase) from the host cells were simultaneously present in the culture supernatant only when the cells were co-cultured with P. acnes. Either anti-CAMP factor serum or desipramine, a selective ASMase inhibitor, significantly abrogated the P. acnes-induced cell death of HaCaT and RAW264.7 cells. Intradermal injection of ICR mouse ears with live P. acnes induced considerable ear inflammation, macrophage infiltration, and an increase in cellular soluble ASMase. Suppression of ASMase by systemic treatment with desipramine significantly reduced inflammatory reaction induced by intradermal injection with P. acnes, suggesting the contribution of host ASMase in P. acnes-induced inflammatory reaction in vivo. Vaccination of mice with CAMP factor elicited a protective immunity against P. acnes-induced ear inflammation, indicating the involvement of CAMP factor in P. acnes-induced inflammation. Most notably, suppression of both bacterial CAMP factor and host ASMase using vaccination and specific antibody injection, respectively, cooperatively alleviated P. acnes-induced inflammation. Conclusions/Significance These findings envision a novel infectious mechanism by which P. acnes CAMP factor may hijack host ASMase to amplify bacterial virulence to degrade and invade host cells. This work has identified both CAMP factor and ASMase as potential molecular targets for the development of drugs and vaccines against

    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/m2) 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. PMID:22253996

    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.

    Background The -308 G/A polymorphism in the tumor necrosis factor (TNF) gene has been implicated in the risk of acne vulgaris, but the results are inconclusive. The present meta-analysis aimed to investigate the overall association between the -308 G/A polymorphism and acne vulgaris risk. Methods We searched in Pubmed, Embase, Web of Science and CNKI for studies evaluating the association between the -308 G/A gene polymorphism and acne vulgaris risk. Data were extracted and statistical analysis was performed using STATA 12.0 software. Results A total of five publications involving 1553 subjects (728 acne vulgaris cases and 825 controls) were included in this meta-analysis. Combined analysis revealed a significant association between this polymorphism and acne vulgaris risk under recessive model (OR = 2.73, 95% CI: 1.37–5.44, p = 0.004 for AA vs. AG + GG). Subgroup analysis by ethnicity showed that the acne vulgaris risk associated with the -308 G/A gene polymorphism was significantly elevated among Caucasians under recessive model (OR = 2.34, 95% CI: 1.13–4.86, p = 0.023). Conclusion This meta-analysis suggests that the -308 G/A polymorphism in the TNF gene contributes to acne vulgaris risk, especially in Caucasian populations. Further studies among different ethnicity populations are needed to validate these findings. PMID:24498378

    The Dermatology-specific Quality of Life (DSQL) instrument is a new tool which has been developed to address the effects of skin disease and its treatment on physical and social functioning and self-perceptions. Previous reports have demonstrated its cross-sectional validity. The current study examines the DSQL's responsiveness to 12 weeks of acne treatment in a placebo-controlled randomized clinical trial. The DSQL change scores were moderately correlated (r = 0.18 to 0.37) with treatment efficacy parameters including: dermatologist's rating of improvement of acne and a skin irritation score, and highly correlated with patient's global rating of acne severity. Within treatment groups, the DSQL discriminated clinically meaningful changes associated with small and moderate effect sizes. The DSQL total score showed statistically significant differences on nearly all comparisons with placebo. The DSQL dimension scores were sensitive to the most effective therapy compared to placebo. Responsiveness benchmarks are provided for small and moderatesized treatment effects. As a comprehensive instrument, the DSQL is a practical and psychometrically sound tool for use in clinical trials in dermatology. PMID:10097621

    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.

    Background. Androgenetic Alopecia in Women (AGA) occurs due to an underlying susceptibility of hair follicles to androgenic miniaturization, caused by androgens. Clinically, AGA is characterized by progressive hair loss, with a marked hair thinning in the fronto-parietal area so that the scalp can be easily seen. Acne vulgaris is androgen-dependent and often affects the skin that has an increased number of oil glands: face, back and chest. Although the sebaceous glands are present on the scalp too, it is very rare to get acne at this site, as the hair acts as a wig and allows the sebum to drain and does not block the pores. Both AGA and Acne Vulgaris are signs of hyperandrogenism. Cyproterone acetate/ethinyl estradiol (2mg/0.035mg) products are authorized for the treatment of androgenetic symptoms in women, such as acne, seborrhea, mild forms of hirsutism and androgenetic alopecia. Our study had a double purpose: - To evaluate the result of the study regimen Melleva 35 (one pill per day, for 3 consecutive months) in patients with moderate to severe acne, suffering also from Androgenetic Alopecia;- To establish the efficacy of the drug on acne and alopecia improvement, both from the doctor’s and patient’s point of view. Patients and methods. After being informed of the aims and procedures of the study, participants provided a written informed consent. A number of 35 female subjects with moderate to severe acne vulgaris remained in the study. The subjects had also been diagnosed as suffering from AGA, on the basis of clinical criteria, including the pattern of hair loss and trichoscopy assessment. Results 83% of study subjects reported that their hair did not continue to fall after 3 months of antiandrogen therapy. The females were evaluated using trichoscopy and the doctor noticed hair regrowth in 77% of the cases. Regarding the improvement of acne lesions after the treatment, 40% of study subjects recorded good improvement and 26% recorded excellent results

  20. Extended-release Formulation of Minocycline in the Treatment of Moderate-to-severe Acne Vulgaris in Patients Over the Age of 12 Years

    2013-01-01

    Oral antibiotics continue to play an important role in the treatment of moderate-to-severe acne. Minocycline is widely used in moderate-to-severe acne. Minocycline has anti-inflammatory properties, activity against Propionibacterium acnes and lipophilicity. An extended-release formulation of minocycline has been introduced. Extended-release minocycline is not bioequivalent to nonmodified release minocycline products and exhibits dose-proportional pharmacokinetics. Food or dairy products did not influence absorption. Efficacy is not dose-dependent, while the incidence of acute vestibular adverse events increases with dose suggesting an optimal dose of 1mg/kg. In two Phase 3 clinical trials, mean percent improvement in inflammatory lesions after 12 weeks of treatment with extended-release minocycline was 43.1 and 45.8 percent compared to 31.7 and 30.8 percent with placebo (P=0.001 and P<0.001, respectively) while the incidence of acute vestibular adverse events was comparable to placebo.

    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. PMID:26796708

    Many therapies exist in the arsenal of drugs available to dermatologists for the treatment of acne vulgaris. Among them, hormonal therapy stands out as a unique and highly efficacious treatment modality. Although some dermatologists may be hesitant to prescribe hormonal therapies, they can be safely and appropriately used in eligible female patients to treat acne vulgaris. Herein, current issues regarding the hormonal treatment of acne in the form of combined oral contraceptives (COCs) are presented, and a practical method for implementing this therapy is proposed. Specifically, drug selection, associated risks, benefits, monitoring, and counseling are discussed, with emphasis on the practicality of use in the clinical setting. PMID:22988652

    Background Acne vulgaris is a common skin condition, which affects most adolescents at some point in their lives. It has been found to have a significant impact on their psychological well-being and has been associated with depression and suicide ideation. Many studies have assessed the impact of acne vulgaris on the quality of life (QoL) in different population subgroups around the world, but there is a dearth of reports from the African subcontinent. This study thus seeks to assess the severity of acne vulgaris and determine its effect on the QoL of adolescents in Lagos, Nigeria. Methods In a cross-sectional survey employing a two-stage sampling method, the severity of acne vulgaris and its impact on the QoL of adolescents attending a senior secondary school in Lagos, Nigeria was assessed using the Global Acne Grading Scale (GAGS) and the Cardiff Acne Disability Index (CADI), respectively. The correlation between the results of the GAGS and CADI was also determined. Results One hundred and sixty adolescent students with acne were recruited, with males accounting for 51.9% and females 48.1%. The mean and standard deviation of the GAGS severity scores were 11.3±5.4 for males and 11.9±5.4 for females. Only one student had severe acne vulgaris (GAGS, 31–38), 10% moderate (GAGS, 19–30), and 89.4% mild (GAGS, 1–18). The overall CADI score was 3.4±3.0, which suggests mild impairment in QoL; however, the solitary student with severe acne had severe QoL impairment. There was a weak positive correlation between the GAGS and the CADI score. Conclusion Most adolescents in our study had mild acne vulgaris, and the overall impact on their QoL was mild. However, the correlation between the psychosocial impact and acne severity was weak. There is a need for similar studies in other parts of the country and for further studies to determine the adequacy of the existing instruments in assessing the impact of acne vulgaris in Nigerian adolescents.

    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. PMID:27015775

    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.

    Recent studies have suggested that dietary factors, specifically glycaemic load, may be involved in the pathogenesis of acne. The aim of this study was to determine the clinical and histological effects on acne lesions of a low glycaemic load diet. A total of 32 patients with mild to moderate acne were randomly assigned to either a low glycaemic load diet or a control group diet, and completed a 10-week, parallel dietary intervention trial. Results indicate successful lowering of the glycaemic load. Subjects within the low glycaemic group demonstrated significant clinical improvement in the number of both non-inflammatory and inflammatory acne lesions. Histopathological examination of skin samples revealed several characteristics, including reduced size of sebaceous glands, decreased inflammation, and reduced expression of sterol regulatory element-binding protein-1, and interleukin-8 in the low glycaemic load group. A reduction in glycaemic load of the diet for 10 weeks resulted in improvements in acne. PMID:22678562

    Acne vulgaris is an exceptionally common, chronic, and recurring disease. It involves multiple etiological factors including follicular hyperkeratinization, increased sebum production, Propionibacterium acnes proliferation, and inflammation. Presently, oral isotretinoin is the only single agent that is effective against all 4 major pathophysiologic features. However, this drug is also responsible for several serious side effects, including teratogenicity. Therefore, it should be used in only the most severe cases and alternative treatment approaches for inflammatory acne, such as initial combination therapy, should be considered first. Combination therapy in inflammatory acne simultaneously targets multiple pathogenic factors. Current guidelines recommend early initiation of combination therapy with a topical retinoid and antimicrobials for mild to moderate inflammatory acne and topical retinoids with oral antibiotics (with or without the use of benzoyl peroxide) for moderate to severe cases of acne, followed by maintenance therapy with topical retinoids. This review evaluates the rationale and clinical evidence for the use of adapalene in combination therapy for inflammatory acne. PMID:16989194

    Few clinical studies have examined the utility of bipolar fractional radiofrequency (FRF) therapy as a treatment for atrophic acne scars and active acne in people with darker skin. This study was designed to compare the safety and efficacy of bipolar FRF therapy as a treatment for atrophic acne scars and acne vulgaris. Twenty-three Japanese patients with atrophic acne scars and mild to severe acne on both cheeks were treated with a bipolar FRF system (eMatrix; Syneron, Yokneam Illit, Israel). Five treatment sessions were carried out at 1-month intervals, and the patients were followed up for 3 months after the final treatment. Assessments of scar severity and the number of acne lesions and 3-D in vivo imaging analysis were performed. Evaluations of the treatment outcomes and their effects on the patients' quality of life (QOL) were also carried out. We demonstrated that the improvement in scar volume was marked in the patients with mild scars and was at least moderate in 23 (57.5%) of the treated areas. With regard to the number of acne lesions, the treated areas exhibited significantly fewer lesions compared with the baseline at each time point (P < 0.05). The patients' assessments of the treatment outcomes and their QOL indicated that both had improved significantly by the end of the study. Furthermore, significant reductions in the patients' sebum levels, skin roughness and scar depth were observed. Bipolar FRF treatment significantly improved the atrophic acne scars and acne of Japanese patients and had minimal side-effects. PMID:25855397

    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

    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. PMID:25845307

    A rich residential microflora is harboured by the distal outer root sheath of the hair follicle and the hair canal - normally without causing skin diseases. Although the basic mechanisms involved in the development of inflammation during acne vulgaris remain unclear, microbial agents might play an important role in this process. In this study we have analyzed by in situ hybridization and immunohistochemistry the expression patterns of two antimicrobial peptides, human beta defensin-1 and human beta defensin-2, in healthy human hair follicles as well as in perilesional and intralesional skin of acne vulgaris lesions such as comedones, papules, and pustules. Strong defensin-1 and defensin-2 immunoreactivity was found in all suprabasal layers of the epidermis, the distal outer root sheath of the hair follicle, and the pilosebaceous duct. Marked defensin-1 and defensin-2 immunoreactivity was also found in the sebaceous gland and in the basal layer of the central outer root sheath including the bulge region. The majority of acne biopsies displayed a marked upregulation of defensin-2 immunoreactivity in the lesional and perilesional epithelium - in particular in pustules - and a less marked upregulation of defensin-1 immunoreactivity. The upregulation of beta-defensin expression in acne vulgaris lesions compared to controls suggests that beta-defensins may be involved in the pathogenesis of acne vulgaris. PMID:11710922

    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. PMID:14708455

    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

    Acne vulgaris is a common skin condition, one that is associated with significant psychological disability. The psychological impairments in acne include higher rates of depression, anxiety, anger and suicidal thoughts. Despite a paucity of clinical research, patients with skin conditions and/or mental health disorders are frequent consumers of dietary supplements. An overlap may exist between nutrients that potentially have both anti-acne and mood regulating properties; examples include omega-3 fatty acids from fish oil, chromium, zinc and selenium. Here we report on five cases of acne treated with eicosapentaenoic acid and antioxidant nutrients. Self-administration of these nutrients may have improved inflammatory acne lesions and global aspects of well-being; the observations suggest a need for controlled trials. PMID:18851733

    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

    Tazarotene is a synthetic retinoid that, depending on the concentration and vehicle, is approved by the US Food and Drug Administration for the topical treatment of acne vulgaris (AV) and plaque psoriasis. Tazarotene is also used as adjunctive treatment for specified clinical manifestations of chronically photodamaged skin (facial fine wrinkling, mottled facial hypopigmentation and hyperpigmentation, and benign facial lentigines), along with comprehensive skin care and photoprotection from sunlight. The gel formulation was released in the United States in 1997, with the cream formulation made available in 2000. Multiple studies are available supporting the effective and safe use of topical tazarotene for each of its indications. This article provides an overview of the pharmacology of topically applied tazarotene, discussing in particular up-to-date information on the efficacy, tolerability, and safety of topical tazarotene for AV, including monotherapy and combination therapy studies. Topical tazarotene 0.1% in both formulations is highly effective in reducing both inflammatory and noninflammatory acne lesions, and can be used in combination with other topical agents, including formulations containing benzoyl peroxide or dapsone 5% gel. Although many patients tolerate the use of topical tazarotene without significant issues or concerns, some patients experience application-site tolerability reactions, which can usually be managed with proper skin care and are less frequent with the cream formulation.

    Acne vulgaris is adebilitating dermatologic disease, and is conventionally treated by laser therapy using a microring resonator system. An evolving understanding of laser-tissue interactions involving Propioni bacterium acneproducing porphyrins, and the development of lasers to target the sebaceous glands, has led to the development of an escalating number of laser light for acne treatment. The results show that the full width at half maximum of the proposed laser pulse of 0.15 nm can be generated using a microring resonator system. The power of the laser is 200 W and the wavelength laser is 1,032 nm, which is proposed as a treatment of acne vulgaris diseases. PMID:22991968

    The psychological impact of acne is determined by various factors including age, sex, personality, grade of disease, scarring, and environmental and ethnic background. Apart from managing the clinical manifestations of acne, clinicians also have to deal with the psychological aspects of the disease by assessing patients' quality of life (QOL) and self-esteem. These measures will aid in better management of acne patients. This study examined the relationship between acne and QOL and self-esteem. The results showed that acne severity may have a considerable adverse impact on QOL and self-esteem. Dermatologists need to emphasize the psychosocial sequelae of acne through awareness programs and encourage medical treatment along with basic psychosomatic remedies in the management of acne.

    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 vulgaris impairs the appearance of an individual and causes psychological irritation. Inflammatory acne lesion is caused by multifactor incorporates in each step of acne pathogenesis. In an attempt to archive inflammatory lesion treatment with the promise of prevention of acne vulgaris, randomized and double-blind studies on the comparison of the efficacies of topical formulations containing 5% sodium ascorbyl phosphate (SAP) and 0.2% retinol, separately as well as in combination application, were conducted. The resulting data showed that SAP reduced the inflammatory lesion by 20.14% and 48.82% within 4 and 8 weeks respectively. Application of the formulation containing retinol slightly improved the treatment efficacy as the lesion reduced by 21.79% and 49.50% after 4 and 8 weeks respectively. The combination treatment significantly reduced the inflammatory lesion by 29.28% after 4 weeks and 63.10% after 8 weeks of application. The most effective treatment was by using the combination of 5% SAP and 0.2% retinol, which incorporated the synergistic effects on lipid peroxidation and sebaceous gland function in addition to the enhancement of SAP permeability by the desquamation of stratum corneum influenced by retinol, keratin plug removal and anti-inflammatory effect of retinol. This study promises for the development of cosmetic products to overcome aesthetic and psychological problems caused by acne vulgaris. PMID:19134126

    Drospirenone 3mg with ethinylestradiol 20microg (Yaz) is a low-dose combined oral contraceptive (COC) administered in a regimen of 24 days of active tablets followed by a short hormone-free interval (4 days; 24/4 regimen). Drospirenone, unlike other synthetic progestogens used in COCs, is a 17alpha-spirolactone derivative and a 17alpha-spironolactone analogue with antimineralocorticoid and antiandrogenic properties. Drospirenone/ethinylestradiol 3mg/20microg (24/4) is approved in the US for the prevention of pregnancy in women, for the treatment of the symptoms of premenstrual dysphoric disorder (PMDD) and for the treatment of moderate acne vulgaris in women who wish to use an oral contraceptive for contraception.Drospirenone/ethinylestradiol 3mg/20microg (24/4) provided 99% contraceptive protection over 1 year of treatment in two large studies. The same treatment regimen over three treatment cycles also significantly improved the emotional and physical symptoms associated with PMDD, and improved moderate acne vulgaris over six treatment cycles in double-blind trials. It was generally well tolerated, with adverse events generally typical of those experienced with other COCs and which were most likely to occur in the first few cycles. Clinical trials indicate that drospirenone/ethinylestradiol 3mg/20microg (24/4) is a good long-term contraceptive option, and additionally offers relief of symptoms that characterise PMDD and has a favourable effect on moderate acne vulgaris.

    Topical retinoids are currently approved by the US Food and Drug Administration for the treatment of acne vulgaris in nonpregnant, nonlactating patients 12 years of age and older. Their efficacy, safety, and tolerability are well documented for inflammatory and noninflammatory acne with studies repeatedly demonstrating a decrease in the number of lesions, significant improvement in acne severity, improvement in the cosmetic appearance of acne, and the prevention of acne lesions through microcomedone formation. There is some variability between prescription retinoid products regarding efficacy, safety, and tolerability; with erythema, peeling, and dryness being common, potential side effects. Due to their efficacious and safe profile, topical retinoids remain the first-line treatment for acne vulgaris. PMID:27416308

    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. PMID:26428932

    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

    Although entrapment of nanoparticles of appropriate sizes at hair follicles has been clarified, there is no report on specific clinical application of this finding. Since sebaceous gland is associated with hair follicle, we hypothesize that effective acne vulgaris treatment/prevention can be achieved by depositing anti-acne agent in nanoparticle form at the hair follicles. Challenge of this strategy, however, lies at the finding of effective anti-acne particles with minimal skin irritation. Here using cellulose-based nanoparticles as nano-reservoir and α-mangostin (an active component isolated from the edible Garcinia mangostana Linn. fruit) as anti-acne agent, we prepare nanoparticles highly loaded with α-mangostin. Ability of the obtained particles to sustained release α-mangostin into synthetic sebum is demonstrated. The obtained mangostin particles are verified for their insignificant skin irritation through the two-week, twice-daily open application test in 20 healthy human volunteers. Excellent entrapment and sustainment of the mangostin nanoparticles at the hair follicles are elucidated in six human volunteers by detecting the presence of α-mangostin at the roots of hairs pulled from the treated skin area. The 4-week-randomized, double-blind, placebo-controlled, split-face study in 10 acne patients indicates significant improvement in acne vulgaris condition on the side twice daily applied with mangostin nanoparticles.

    Aim. The aim of this study was to evaluate the platelet counts and the mean platelet volume in patients who received isotretinoin for the treatment of acne vulgaris. Method. A total of 110 patients were included in this retrospective study. Complete blood count parameters were recorded prior to and three-months following the treatment. Results. Both platelet counts and the mean platelet volume were significantly decreased following the treatment. No significant differences were noted on the levels of hemoglobin, hematocrit, and white blood cell count. Conclusion. Platelet counts and mean platelet volume significantly decreased following isotretinoin treatment. Since the decrease of platelet counts and the mean platelet volume was seen concomitantly, it is concluded that the effect of isotretinoin was through the suppression of bone marrow. PMID:24605049

    Acne vulgaris (AV) is an inflammatory skin disease characterized by the presence of comedones, papules, pustules, and nodules. Consensus guidelines recommend the use of combination therapy using different drugs with complementary mechanisms of action to best address as many acne pathogenic factors as possible at the same time. Topical acne medications exist as individual agents that may be combined in physician-recommended regimens or as pre-formulated fixed-dose combination products. In addition, there are several new and promising topical therapies currently being developed that work by different mechanisms of action from traditionally used acne therapies. The following review will cover commonly used drugs, newcomers to the market, and what the future holds for the topical treatment of AV. PMID:26741391

    Acne is the most common disease of the skin, yet only a fraction of acne sufferers are treated with prescription products by physicians. There is, however, a large and expanding market for over-the-counter (OTC) medications, many of which are not only effective but also well tolerated and cosmetically elegant. Given the presence of OTC acne medications on the television, the Internet, and store shelves, patients will be acutely aware of these OTC remedies and will have questions. Patients will expect dermatologists to advise them regarding products to use either as a sole therapy or in combination with prescription drugs. Recently, combinations of OTC acne medications in treatment regimens or "kits" have gained popularity and appear to have increased patient compliance. Quality-of-life outcomes from OTC medication use, in at least one study, have demonstrated good benefit. The most common OTC ingredients include benzoyl peroxide, a potent antibacterial agent, and salicylic acid, a mild comedolytic and antiinflammatory medication. Other, less-common OTC ingredients include sulfur, sodium sulfacetamide, and alpha hydroxy acids. Zinc, vitamin A, tea tree oil, and ayurvedic therapies also are available OTC for acne. Additional and better studies are needed to clarify the benefit of these latter medications. PMID:18786494

    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. PMID:23886975

    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. PMID:19738184

    2016-01-01

    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 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. PMID:19932324

A total of 17,345 inhabitants were included in this study. Of these, 1,399 were found to have acne. No acne was found in subjects under 10 years of age, and only 1.6% in the 10-year-old group had acne. Prevalence then increased rapidly with age, up to 46.8% in the 19-year-old group. After that, it declined gradually with age. Acne was rare in people over 50 years of age. In subjects in their late teens and 20s, acne was more prevalent in males, while in those over 30 years of age it was more prevalent in females. In subjects with acne, 68.4% had mild; 26.0% had moderate and 5.6% had severe acne. In adult acne, persistent acne was much more common (83.3%) than late-onset acne (16.7%). Smoking and drinking were found to be associated with adolescent acne, while no association was found between diet and acne. These results suggest that the prevalence of acne in the Chinese population is lower than that in Caucasian populations, and that adult acne is not uncommon in Chinese subjects. PMID:21710106

    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. PMID:24553997

    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. PMID:21284283

    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.

    The purpose of our studies was to verify efficacy and skin compatibility of a medical face care system containing 2% lactic acid (LA) as active ingredient in a specially designed vehicle (Follicle Targeting System) in adult subjects with mild acne vulgaris. The first study (46 patients) demonstrated superiority of 2% LA in comparison to 2% salicylic acid with respect to number of comedones and inflammatory lesions. The second study evaluated 90 patients receiving distinct combinations of face care products (Eucerin) Impure Skin, Hamburg, Germany), i.e. cleansing gel, facial tonic (2% LA) and cream gel (2% LA). All treatments were performed twice daily over a 12 weeks period. Lesion counts, cyanoacrylate biopsies and determination of quality of life by questionnaires were performed at different timepoints. A reduction of comedones by 56% corresponding to an 46% increase of quality of life index was demonstrated in patients applying cleansing gel, facial tonic and cream gel. For the first time we were able to show a significant improvement concerning the quality of life after using a new face care line. Especially adults with mild forms of acne may benefit from this effective skin care regimen. PMID:18492134

    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.

    Context: Acne vulgaris (AV) is a common disease affecting all ages and ethnic groups. Androgens, skin and serum lipids, inflammatory signaling and regulatory neuropeptides seem to be involved in this multi-factorial process. Aim: The aim of this work was to determine hormonal levels and lipid profile in non-obese, non-hirsute females with AV. Subjects and Methods: A total of 60 non-obese, non-hirsute female cases with different grades of AV and 60 age- and gender-matched healthy volunteers were included. Measurement of serum total and free testosterone, sex hormone binding globulin (SHBG), estradiol and progesterone and blood lipids was done during the luteal phase of the menstrual cycle. Results: Total testosterone, free testosterone (FT) and progesterone levels were significantly higher (P < 0.001 for all) while estradiol levels (P < 0.001) and SHBG (P < 0.01) were significantly lower in cases than controls. Total cholesterol and low density lipoprotein cholesterol (LDL-C) levels were significantly higher (P < 0.001 for both) while high density lipoprotein cholesterol (HDL-C) and apolipoprotein A-1 (ApoA-1) levels were significantly lower (P < 0.001 for both) in cases than controls. Higher values of FT (P = 0.03) and SHBG (P = 0.02) and lower values of estradiol (P = 0.04) levels were significantly in favor of severe acne. Higher values of cholesterol (P < 0.001) and LDL-C (P = 0.03) and lower values of HDL-C (P = 0.01) and ApoA-1 (P = 0.02) levels were significantly associated with severe acne. Conclusion: Changes in hormone levels and lipid profile in non-obese and non-hirsute females with AV should be considered in disease pathogenesis and in treatment prescription of these patients.

    Background: Traditional Persian medicine (TPM) is based on humors theory. Temperament or mizaj is the result of a combination of four fundamental humors called blood, phlegm, yellow bile, and black bile. Like any other diseases, acne is the result of humoral imbalance. Acne is a highly prevalent dermatological problem, which has both physical and psychological effects on patients. The aim of this study was to determine the etiology of acne formation and natural remedies from the perspective of Persian scientists. Methods: The etiology and treatment of acne were collected and analyzed from selected TPM medical textbooks. Some selected plants in these books were assessed in tabular format and their anti-acne activities were compared with modern medicine’s databases. Results: In the acne treatment, considering six essential schemes for health, diet and herbal remedies as well as manipulation are recommended. Although the mentioned herbs in acne treatment have antibacterial, anti-inflammatory, and antioxidant effects; however, some have special proven effects on the acne formation process. There is also a strong relationship between the digestive system and skin. This paper was rendered to show ancient Persian scholar’s viewpoints on acne and its treatment. Conclusion: Some reported remedies might be beneficial towards further studies on acne treatment. PMID:26722141

    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

    Hormones and androgens play an important role in the pathogenesis of acne. Multiple hormonal modulators are now available for the treatment of acne. The efficacies and side effects of currently available hormonal agents are reviewed here including the use of oral contraceptives, spironolactone, flutamide, cyproterone acetate, finasteride, and cortexolone 17α-propionate. Hormonal therapies are an efficacious treatment option for acne among females. With the growing need to reduce antibiotic exposures, hormonal therapies should be more widely studied and incorporated into acne treatment strategies. PMID:27416311

    Background Acne vulgaris is an inflammatory disorder of the pilosebaceous unit. Aim To confirm that BGM (bakuchiol, Ginkgo biloba extract, and mannitol) complex increases the established clinical efficacy of adapalene 0.1% gel in patients with acne. Methods A clinical trial was conducted in acne patients. A total of 111 subjects received adapalene 0.1% gel and BGM complex or vehicle cream for 2 months. Assessments comprised Investigator Global Assessment (IGA), global efficacy, seborrhea intensity, inflammatory and non-inflammatory lesions, and subject perception, as well as overall safety and local tolerance and quality of life. Results At the end of the trial, inflammatory and non-inflammatory lesions, IGA, global efficacy, and seborrhea intensity had significantly improved in both treatment groups. Differences were statistically significant (P<0.05) in favor of BGM complex for inflammatory lesions as well as IGA and seborrhea intensity. Global efficacy assessments and subject perception confirmed the superiority of BGM complex-including treatment over the comparative combination. Quality of life had improved more with the active combination than with the vehicle combination. In the active group, four subjects had to interrupt temporarily BGM complex and 12 adapalene compared to seven subjects interrupting the vehicle and eleven adapalene in the vehicle group. One subject withdrew from the trial due to an allergy to adapalene. The majority of all events were mild. Conclusion BGM complex improves the treatment outcome of adapalene 0.1% gel in patients with acne vulgaris. Overall, safety and local tolerance of BGM complex were good. PMID:25914553

    Little is known about the altered lipid metabolism-related transcriptional events occuring in sebaceous glands of patients with acne vulgaris. Peroxisome proliferator-activated receptor (PPAR)γ, a lipid-activated transcription factor, is implicated in differentiation and lipid metabolism of sebocytes. We have observed that PPARγ and its target genes, ADRP (adipose differentiation related protein) and PGAR (PPARγ angioprotein related protein) are expressed at lower levels in sebocytes from patients with acne than in those from healthy controls (HCs) Furthermore, endogenous PPARγ activator lipids such as arachidonic acid-derived keto-metabolites (e.g. 5KETE, 12KETE) are increased in acne-involved and nonacne-involved skin of patients with acne, compared with skin from healthy individuals. Our findings highlight the possible anti-inflammatory role of endogenous ligand-activated PPARγ signaling in human sebocyte biology, and suggest that modulating PPARγ- expression and thereby signaling might be a promising strategy for the clinical management of acne vulgaris.

    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 4(th) 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.

    Combination therapy is an effective approach to simultaneously target multiple pathogenic factors of acne. International consensus guidelines recommend the use of topical retinoids and benzoyl peroxide (BPO) for acne treatment. These drugs are often prescribed as a free combination without any safety concern associated with antibiotic use. A 3-week, randomized, controlled, investigator-blinded, single-center, bilateral (split-face), dose-assessment study was conducted comparing the cutaneous tolerability of 2 adapalene-BPO fixed-dose combination products versus various concentrations of BPO monotherapy applied once daily. Sixty healthy participants were randomized to one of the following treatment groups: adapalene 0.1%-BPO 2.5% combination product versus BPO 2.5% monotherapy; adapalene 0.1%-BPO 2.5% combination product versus BPO 5% monotherapy; adapalene 0.1%-BPO 5% combination product versus BPO 5% monotherapy; and adapalene 0.1%-BPO 5% combination product versus BPO 10% monotherapy. Assessments included total sum score (TSS) of irritation signs/ symptoms (erythema, scaling/desquamation, dryness, pruritus, stinging/burning) averaged over all postbaseline visits, individual irritation signs/symptoms (worst score), and adverse events. The overall cutaneous tolerability profile of the adapalene 0.1%-BPO 2.5% combination product was better than the combination with BPO 5% and similar to BPO 2.5% or 5% monotherapy. The combination product with BPO 5% induced significantly more irritation than BPO 5% monotherapy (P < .001) or BPO 10% monotherapy (P = .001). In conclusion, the new fixed-dose adapalene 0.1%-BPO 2.5% combination product provided the best overall cutaneous tolerability profile relative to BPO monotherapy. PMID:18441854

    The objective of the present study was to develop a nanocarrier based formulation of nadifloxacin and to investigate its in vitro antimicrobial effect against Propionibacterium acnes. Nanocarrier based microemulsion formulations were prepared by aqueous titration method, using oleic acid as oil phase, Tween-80 as surfactant and ethanol as co-surfactant in different ratios. This procedure yielded monodisperse microemulsions exhibiting a mean droplet size in the range of 95-560 nm. This range of particle size is good to treat follicle related disorders like acne vulgaris because the size of follicles is in the range of 50-100 microm. Furthermore the optimized formulations were characterized for surface morphology by transmission electron microscopy and refractive index. The permeation studies were carried out using rat skin mounted in Franz diffusion cells. Flux of the optimised formulation was 2.24 times that of control. The diameter of inhibition zone of the microemulsion was found good but smaller than that of a clindamycin disc because of the higher therapeutic efficacy of clindamycin against P. acnes. The results indicated that the developed microemulsion shows promising results against P. acnes bacteria and may be a good approach for acne treatment. PMID:21434572

    Acne vulgaris is an inflammatory disorder of the pilosebaceous follicle. It is well established that androgen hormones play a major role in sebum production and excretion, and are vital in the pathogenesis of acne. Isotretinoin notwithstanding, hormonal therapies such as combined oral contraceptives (COCs) and spironolactone are the only treatments that can affect sebum production and the androgen component of acne. Contraceptives are also used during isotretinoin therapy for pregnancy prevention. It is important for a dermatologist to be familiar with all the available methods of contraception to provide essential counseling to patients. The aim of this paper is to review the role of hormones in acne pathogenesis, discuss the use of hormonal therapies for acne, and detail various alternative contraceptive methods in relation to isotretinoin treatment and pregnancy prevention.

    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. PMID:25914552

    Acne vulgaris is a common and distressing condition that typically presents in adolescents and young adults. The aim of this split-face, single-blind, randomized, controlled study was to determine if combination therapy with pneumatic broadband light (PBBL) plus adapalene gel 0.3% is superior to adapalene gel 0.3% monotherapy in the treatment of acne. Results indicated that the addition of PBBL to topical regimens may lead to quicker results and therefore may improve treatment adherence to topical therapies in acne patients. PMID:27529709

    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.

    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 pathophysiology of acne vulgaris depends on active sebaceous glands, implying that selective destruction of sebaceous glands could be an effective treatment. We hypothesized that light-absorbing microparticles could be delivered into sebaceous glands, enabling local injury by optical pulses. A suspension of topically applied gold-coated silica microparticles exhibiting plasmon resonance with strong absorption at 800 nm was delivered into human pre-auricular and swine sebaceous glands in vivo, using mechanical vibration. After exposure to 10-50 J cm(-2), 30 milliseconds, 800 nm diode laser pulses, microscopy revealed preferential thermal injury to sebaceous follicles and glands, consistent with predictions from a computational model. Inflammation was mild; gold particles were not retained in swine skin 1 month after treatment, and uptake in other organs was negligible. Two independent prospective randomized controlled clinical trials were performed for treatment of moderate-to-severe facial acne, using unblinded and blinded assessments of disease severity. Each trial showed clinically and statistically significant improvement of inflammatory acne following three treatments given 1-2 weeks apart. In Trial 2, inflammatory lesions were significantly reduced at 12 weeks (P=0.015) and 16 weeks (P=0.04) compared with sham treatments. Optical microparticles enable selective photothermolysis of sebaceous glands. This appears to be a well-tolerated, effective treatment for acne vulgaris. PMID:25748556

    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

    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).

    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 17β-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.

    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

    Acne vulgaris, a disorder of the pilosebaceous unit, is one of the most commonly encountered conditions in dermatology practice. Effective treatment of acne vulgaris is important in that it can prevent psychosocial distress and physical scarring. Systemic therapeutic options are available for moderate to severe acne. It is imperative that the safe and effective treatment revolves around the health care provider's familiarity of side effects of various treatments. In this article, the side effects and monitoring guide for the most commonly prescribed systemic agents for acne vulgaris are reviewed. PMID:27015778

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

    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

    Despite the common recommendation to wash the face twice daily with a mild cleanser, there is little published evidence to support the practice. Indeed, while the general public believes that cleaner skin will result in fewer blemishes, dermatologists often warn that overwashing and scrubbing can exacerbate the condition. To clarify the effect of frequency of face washing on acne vulgaris, we designed a single-blinded, randomized, controlled clinical trial to be conducted on males with mild to moderate acne vulgaris. Subjects washed their faces twice daily for 2 weeks with a standard mild cleanser before being randomized to one of three study arms, in which face washing was to be done once, twice, or four times a day for 6 weeks. At the end of the study no statistically significant differences were noted between groups. However, significant improvements in both open comedones and total noninflammatory lesions were observed in the group washing twice a day. Worsening of acne condition was observed in the study group washing once a day, with significant increases in erythema, papules, and total inflammatory lesions. We concluded that slight support exists, both in terms of efficacy and convenience, for the recommendation to wash the face twice daily with a mild cleanser. However, excessive face washing may not be as culpable as previously thought. PMID:17014635

    Boehncke et al. suggested that decorative cosmetics can improve the quality of life (QOL) of skin diseases. But dermatologists sometimes discourage female acne patients from applying make-up since decorative cosmetics are considered one of the aggravating factors for acne eruptions. The purpose of this study is to assess whether make-up application interferes with acne treatments and how QOL changes when the make-up items are designed for acne patients and used in order to disguise acne eruptions. Eighteen female acne patients were trained by a make-up artist and advised to apply acne-designed basic and decorative cosmetics for 2 to 4 weeks while their acne was appropriately treated. The acne-severity and QOL of patients were assessed before and after the study. The results revealed that the number of acne eruptions decreased even though patients were applying make-up. The QOL scores of Skindex-16, GHQ30 and anxiety state index greatly improved. Our results suggest that dermatologists should encourage acne patients to utilize appropriate make-up to improve their QOL. PMID:16048760

    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

    Acne vulgaris is one of the most common skin diseases in adolescents. In the present study, we aimed to evaluate the effectiveness and safety of topical 5-aminolevulinic acid (ALA)-mediated photodynamic therapy (PDT) for the treatment of severe acne in Chinese adolescent patients. Twenty-one Chinese adolescent patients aged 12-18 years with Pillsbury III-IV severe facial acne were treated with three courses of ALA-PDT. A 5% ALA lotion was applied topically for 60 min followed by irradiation with light-emitting diode light at 633 nm with a light intensity of 75-80 mW/cm(2) and a light dose of 90-96 J/cm(2) . Clinical assessment was conducted before and after each treatment, and at each follow-up session. The total effective rates were 85.71%, 90.48%, and 95.23% after the three PDT sessions, and at the 4- and 8-week follow ups, respectively. ALA-PDT is an effective treatment for severe adolescent acne vulgaris, and is associated with mild and reversible side-effects. PMID:25772520

    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.

    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.

    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. PMID:23576169

    Background and Aims: Recent reports indicate that a variety of light-based devices have been used for acne treatment and skin rejuvenation. A new technology combining intense pulsed light with negative pressure, photopneumatic technology, has recently attracted interest. The present study assessed acne treatment and skin rejuvenation with this novel approach Subjects and Methods: Acne, 450 nm tip. Five Japanese volunteers (1 male, 4 female; mean age 28.6 yr; skin type III) with mild to moderate/moderate active acne participated. The face was treated with 2 sessions, 2 weeks apart. Biopsies were obtained immediately after the first session and 1 week after the second session, and routinely processed for transmission electron microscopy (TEM). Rejuvenation, profusion tip with topical preparation. In 5 Japanese volunteers (3 male, 2 female; mean age 37.6 yr, skin type III), the volar aspect of both forearms was treated with the 530 nm head at P6 (around 12 J/cm2). The left arm was then treated with a pre-infused profusion tip and vacuum only. Four sessions were given, 14-day intervals. Biopsies were taken from both arms 2 weeks after the 2nd session and 3 weeks after the 4th session. One-half of each biopsy was assessed with histo-and immunohistochemistry, and the other with TEM. Results Acne trial: A combination of physical extraction of comedones, mild photothermal damage of the follicle and damage to identified bacilli was noted post-treatment, with macroscopic improvement of the skin. Rejuvenation with profusion: Significant morphological and immunohistochemical differences were seen between the control and profusion-treated arms at the first assessment. These differences became less significant at the 2nd assessment. Conclusions Macroscopically and histologically, photopneumatic technology improved acne lesions, suggesting a synergistic effect between the components of the technology.

    Acne vulgaris affects up to 80% of people 11 to 30 years of age, and scarring can occur for up to 95% of these patients. Scarring may be pitted or hypertrophic in nature, although in most cases it is atrophic. Atrophic acne scarring follows dermal collagen and fat loss after moderate to severe acne infection. Injectable poly-L-acid (PLLA) is a biocompatible, biodegradable, synthetic polymer device that is hypothesized to enhance dermal volume via the endogenous production of fibroblasts and, subsequently, collagen. The gradual improvements in cutaneous volume observed after treatment with injectable PLLA have been noted to last up to 2 years. The case studies presented describe the use of injectable PLLA to correct dermal fat loss in macular atrophic acne scarring of the cheeks. Two female patients underwent three treatment sessions with injectable PLLA over a 12-week period. At each treatment session, the reconstituted product was injected into the deep dermis under the depressed portion of the scar. Both patients were extremely pleased with their results at, respectively, 1- and 4-year follow-up evaluations. Patients experienced minimal swelling and redness after injection and no product-related adverse events such as papule and/or nodule formation. The author believes these data suggest that injectable PLLA is a good treatment option for the correction of macular atropic scarring with thin dermis (off-label use), particularly compared with other injectable fillers currently used for this indication that have shorter durations of effect.

    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

    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. PMID:25903443

    Treatment options for acne vulgaris are enhanced by laser and light therapy. Both visible and laser light are effective treatments for acne. Visible light and many lasers target Propionibacterium acnes porphyrins while others act as anti-inflammatory mediators or reduce sebaceous gland activity. Compared with topical and systemic therapies, laser and light therapies have few if any side effects and appear to be safe during pregnancy. If patients prefer at home light treatments, several devices are currently available and have been shown to have efficacy. Ultimately, combining laser and light with topical therapy may well become the mainstay of acne treatment. PMID:27015782

    Propionibacterium acnes (P. acnes) is a Gram-positive bacterium strongly associated with acne infection. While many antimicrobial agents have been used in clinic to treat acne infection by targeting P. acnes, these existing anti-acne agents usually produce considerable side effects. Herein, we report the development and evaluation of liposomal lauric acids (LipoLA) as a new, effective and safe therapeutic agent for the treatment of acne infection. By incorporating lauric acids into the lipid bilayer of liposomes, we observed that the resulting LipoLA readily fused with bacterial membranes, causing effective killing of P. acnes by disrupting bacterial membrane structures. Using a mouse ear model, we demonstrated that the bactericidal property of LipoLA against P. acne was well preserved at physiological conditions. Topically applying LipoLA in a gel form onto the infectious sites led to eradication of P. acnes bacteria in vivo. Further skin toxicity studies showed that LipoLA did not induce acute toxicity to normal mouse skin tissues, while benzoyl peroxide and salicylic acid, the two most popular over-the-counter acne medications, generated moderate to severe skin irritation within 24 h. These results suggest that LipoLA hold a high therapeutic potential for the treatment of acne infection and other P. acnes related diseases. PMID:23495239

    The majority of adolescents with skin of color in the United States and other westernized civilizations develop acne vulgaris. Indigenous populations of children and teenagers with skin of color may not develop acne when raised on a paleolithic diet, suggesting the Western diet is the rudiment of acne vulgaris. Differences exist in the presentation of and therapy for acne in teenagers with skin of color, largely due to the increased risk for hyperpigmentation, scarring, and keloid formation, as well as style- and skin care-related exacerbating factors. The primary goal of acne therapy in adolescents with skin of color is the prevention of long-term sequelae such as keloid formation. This article provides a brief overview of the treatment of acne vulgaris in adolescents with skin of color. PMID:23961520

    Many medications are available for the management of acne. The armamentarium includes topical retinoids (ie, adapalene, tazarotene, tretinoin), antimicrobial and antibacterial agents (ie, benzoyl peroxide, clindamycin, erythromycin, sulfacetamide with or without sulfur), oral antibiotics (ie, doxycycline, minocycline, tetracycline), hormonal agents (ie, oral contraceptives, spironolactone), and systemic retinoids (ie, isotretinoin). Acne usually is treated with combination therapy to address its multifactorial pathophysiology. The combination of clindamycin 1%-benzoyl peroxide 5% gel, available as a stable formulation in a single tube, is efficacious and well-tolerated. The product's excipients, glycerin and dimethicone, minimize treatment-related irritation, thereby increasing patient compliance. Clindamycin-benzoyl peroxide may be well-tolerated when applied with topical retinoids, creating a more targeted and complete treatment strategy. PMID:17966494

    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 42 130 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 18 477, suggesting that at least 18 477 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. PMID:22374611

    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 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.

    Acne is a chronic disease of the pilosebaceous unit which is most common during adolescence. Four factors are believed to play a key role in the development of acne lesions: excess sebum production, disturbed keratinization within the follicle, colonization of the pilosebaceous duct by Propionibacterium acnes, and the release of inflammatory mediators into the skin. Consequently, in order to effectively and rapidly reduce acne lesions, treatments need to address as many of these underlying factors as possible. Currently, about half of patients have poor adherence to acne treatments. To overcome this limitation, treatments need to be developed which are well tolerated by patients, and easy for them to use, handle and apply. Topical monotherapies for acne such as retinoids and antimicrobials by themselves have a restricted range of actions against the pathogenic factors of acne. Instead, the Global Alliance to Improve Outcomes in Acne Group recommends combination therapy with a topical retinoid and an antimicrobial agent as the preferred approach for almost all acne patients. The principal advantage of such combinations is that they target more of the underlying pathogenic factors of acne than individual monotherapies and this results in faster and more complete clearing of acne lesions. Fixed-dose combinations are also more convenient than applying two medications separately, which leads to improved adherence with the regimen. By normalizing desquamation, the retinoid component of these combinations allows entry of the antimicrobial agent into the pilosebaceous unit resulting in faster clearance of P. acnes. In conclusion, topical retinoid/antimicrobial fixed-dose combinations represent a rational approach for the treatment of acne. They should be considered as the cornerstone of acne management and should be used much more in the future. PMID:26059819

    Acne vulgaris is a prevalent skin condition that can cause disfiguring residual scarring. While the complete removal of acne scars is unlikely, several treatments exist that can improve the appearance of acne scars. Dermal fillers offer a simple, nonsurgical corrective procedure that can provide improved skin texture. Dermicol-P35 (Evolence [Ortho Dermatologics, Skillman, NJ]) is a new, highly purified, ribose cross-linked, porcine collagen-based dermal filler that has demonstrated low immunogenicity and results that persist for at least 12 months. This article presents the aesthetic results of a male patient treated with Dermicol-P35 for severe facial acne scars. PMID:19577176

    Background Acne vulgaris is a chronic skin disease with a high prevalence. Left untreated or inadequately treated, acne vulgaris can lead to psychological and physical scarring, as well as to unnecessary medical expenses. Oral isotretinoin is an effective treatment for severe resistant nodular and conglobate acne vulgaris. A regimen consisting of a fixed-dose combination of adapalene and benzoyl peroxide gel, 0.1%/2.5% (A-BPO) with oral doxycycline 100 mg (A-BPO/D) has been demonstrated to be efficacious and well tolerated in patients with severe acne and may be an alternative to oral isotretinoin for some patients with severe acne. Objective The objective of this analysis was to compare the relative efficacy and associated costs of A-BPO/D versus oral isotretinoin. Methods In this analysis, comparisons of relative efficacy were made using previously published studies involving similar patient populations with severe acne that warrant the use of oral isotretinoin. The pricing for oral doxycycline and oral isotretinoin was estimated based on the maximum allowable cost from 9 states, and the pricing for A-BPO was calculated as the range between the average wholesale price and the wholesale acquisition cost. For this analysis, 2 treatment models were generated to compare costs: (1) a basic treatment model that examined the costs of an initial regimen of either A-BPO/D or oral isotretinoin without considering probable outcomes, and (2) a long-term model that factored in likely treatment outcomes and subsequent treatments into associated costs. The basic treatment model assumed that patients would be prescribed a single regimen of A-BPO/D for 12 weeks or oral isotretinoin for 20 weeks. The long-term model considered the probability of each treatment successfully managing patients' acne, as well as likely additional regimens of A-BPO monotherapy or an additional regimen of oral isotretinoin. As a result of different treatment durations, the costs for each treatment were

    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. PMID:23010007

    Background: Various treatment modalities including non-invasive methods such as chemical peels, topical retinoids, microdermabrasion, minimally invasive techniques such as microneedling, fractional lasers, microneedling radiofrequency devices and invasive procedures such as acne scar surgeries and ablative lasers are used for acne scars, each with its own unique advantages and disadvantages. This study is a retrospective assessment of efficacy and safety of microneedling fractional radiofrequency in the treatment of acne scars. Methods: Thirty one patients of skin types III-V with moderate and severe facial acne scarring received four sequential fractional radiofrequency treatments over a period of 6 months with an interval of 6 weeks between each session. Goodman & Baron's acne scar grading system was used for assessment by a side by side comparison of preoperative and post- operative photographs taken at their first visit and at the end of 3 months after the last session. Results: Estimation of improvement with Goodman and Baron's Global Acne Scarring System showed that by qualitative assessment of 31 patients with grade 3 and grade 4 acne scars, 80.64% showed improvement by 2 grades and 19.35% showed improvement by 1 grade. Quantitative assessment showed that 58% of the patients had moderate, 29% had minimal, 9% had good and 3% showed very good improvement. Adverse effects were limited to transient pain, erythema, edema and hyperpigmentation. Conclusion: Microneedling fractional radiofrequency is efficacious for the treatment of moderate and severe acne scars. PMID:25136209

    The use of fixed combinations in acne vulgaris (acne) is very common, however comparative clinical trial data are limited. Cutaneous tolerability can influence patient compliance, and concerns about skin irritation with topical acne treatments have lead to a number of comparative split-face studies.
    Recently, a new fixed combination product was introduced (clin 1.0%-BP 3.75% gel) that was shown to be effective in reducing both inflammatory and noninflammatory lesions in moderate to severe acne. Here, we assess the tolerability of clin 1.0%-BP 3.75% gel compared with adap 0.1%-BP 2.5% gel in healthy volunteers with no apparent facial redness or dryness over 21-days, using a split-face methodology.
    Especially over the first two weeks of treatment, clin 1.0%-BP 3.75% gel was more tolerable than adap 0.1%-BP 2.5% gel, with statistically significant differences in cumulative change from baseline starting as early as day 8 (dryness) and day 9 (erythema), and composite index on days 8-12 and 16. Transepidermal water loss was less with clin 1.0%-BP 3.75% gel, although the difference was not statistically significant.

    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

    Objective To examine recent studies on the effect of mobile and electronic (ME)-health technology on adherence to acne treatment. Background With emerging use of ME-health technology, there is a growing interest in evaluating the effectiveness of the tools on medication adherence. Examples of ME-health technology-based tools include text message-based pill reminders and Web-based patient education. Methods MEDLINE, Cochrane Library, and Web of Science were searched for articles on adherence to acne treatment published through November 2013. A combination of search terms such as “acne” and “adherence” or “compliance” were used. Results Adherence to oral acne medication was higher than for topical acne medication. The frequency of office visits was also an influencing factor for acne treatment adherence. The telephone-based reminders on a daily basis did not improve acne patients’ medication adherence, whereas the Web-based educational tools on a weekly basis had a positive effect on medication adherence in acne treatment. Conclusion In using ME-health interventions, factors such as medication dosage forms, frequency of intervention, and patients’ preferences should be taken into consideration. Developing disease-specific text message reminders may be helpful to increase adherence rates. In addition, a combination of text message reminders with another type of intervention may improve medication adherence. PMID:24600239

    PubMed

    Harper, Julie C

    2009-01-01

    ABSTRACT One of the primary factors contributing to the development of acne vulgaris is excess sebum. Sebaceous glands and sebum excretion are regulated, at least in part, by androgen hormones. Acne treatments that block this androgen effect include spironolactone and combination oral contraceptives (COC). Three COC are now FDA approved to treat moderate acne. Dermatologists must become experts at prescribing these hormonal contraceptives. Likewise, it is vital to be aware of contraindications to hormonal contraceptive therapy. Proper patient selection relies on an appropriate medical history and an assessment of blood pressure. A pelvic exam and/or Papanicolaou smear are not required prior to initiating therapy with a COC. It is important to counsel patients about potential adverse effects of COC pills and to establish appropriate expectations concerning acne improvement. PMID:19845722

    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.

    Acne is a common affliction among many teens and some adults that usually resolves over time. However, the severe sequela of acne scarring can lead to long-term psychological and psychiatric problems. There exists a multitude of modalities to treat acne scars such as more invasive surgical techniques, subcision, chemical peels, ablative lasers, fractional lasers, etc. A more recent technique for the treatment of acne scars is nonablative radiofrequency (RF) that works by passing a current through the dermis at a preset depth to produce small thermal wounds in the dermis which, in turn, stimulates dermal remodeling to produce new collagen and soften scar defects. This review article demonstrates that out of all RF modalities, microneedle bipolar RF and fractional bipolar RF treatments offers the best results for acne scarring. An improvement of 25%–75% can be expected after three to four treatment sessions using one to two passes per session. Treatment results are optimal approximately 3 months after final treatment. Common side effects can include transient pain, erythema, and scabbing. Further studies are needed to determine what RF treatment modalities work best for specific scar subtypes, so that further optimization of RF treatments for acne scars can be determined.

    Propionibacterium acnes is the primary pathogenic agent responsible for acne vulgaris on the skin and hair follicles. Overgrowth of this bacterium inhibits growth and promotes follicular inflammation, with an associated increase in pro-inflammatory cytokine production. P. acnes has therefore been considered the main target for the prevention and medical treatment of acne vulgaris. The aim of this study was to evaluate the in vitro anti-P. acnes and anti-inflammatory properties of 6 compounds isolated from Nostoc commune. One of these compounds, nostocionone (Nost), and one of its derivatives, NostD3 [(1E,4E)-1-(3,4-dihydroxyphenyl)-5-(2,6,6-trimethylcyclohex-1-enyl)penta-1,4-dien-3-one], significantly inhibited P. acnes growth. Furthermore, we investigated the effects of Nost and NostD3 on heat-killed (hk) P. acnes-induced inflammation in macrophages. Both Nost and NostD3 suppressed hk P. acnes-induced nitric oxide (NO) production through the suppression of inducible NO synthase expression, following inactivation of nuclear factor kappa B. Taken together, our findings suggested that both Nost and NostD3 were promising agents for the treatment of acne vulgaris, and that NostD3 showed higher efficacy than Nost. PMID:24699048

    Most patients with acne have some degree of facial scarring even after their acne resolves, extending the period of psychosocial distress. Unfortunately, management of acne scars remains challenging. Many treatments for post-acne scarring including chemical peels, skin needling, laser resurfacing, surgical repair, subcision lifting, and punch elevation lifting, are limited by moderate and unpredictable results, significant morbidity, and substantial patient investments in time and money. The most recent addition to the armamentarium is tissue augmentation with soft tissue fillers, including a recently approved polymethylmethacrylate-collagen filler. Matching individual patient needs to the appropriate treatment is crucial. While many patients with acne scars have unrealistic expectations about treatment outcomes, open, honest, and realistic dialogue regarding their treatment options and concerns can facilitate realistic expectations. This article is based on a consensus discussion by the authors, who all have experience managing post-acne scarring, as well as the content of a series of live CME-accredited symposia in connection with major dermatology meetings.

    We conducted a randomized controlled trial in patients with acne vulgaris with moderate to severe inflammatory lesions. The patients were assigned to the following three treatment groups: group A received monotherapy with 0.1% topical adapalene gel for 4 weeks; group B received combination therapy with 0.1% topical adapalene gel and 600 mg oral faropenem for 2 weeks followed by 0.1% topical adapalene gel alone for 2 weeks; and group C received combination therapy with 0.1% topical adapalene gel and 600 mg oral faropenem for 4 weeks. The result of the analysis indicated that the percentage reduction in inflammatory lesion counts after 2 weeks of treatment was significantly higher in groups B and C than in group A (P < 0.05). After 4 weeks of treatment, group C showed significantly higher percentage reduction in inflammatory lesion counts than in groups A and B (P < 0.05), whereas no significant difference was noted between the latter two groups. Adverse reactions included dryness and irritation at the adapalene application sites that were observed in 10.1% of cases (16/158 patients) and diarrhea and loose stool because of oral faropenem that were observed in 7.5% of cases (8/106 patients). Taken together, our results suggest that combination therapy with oral antibiotics and adapalene results in earlier improvement in patients with moderate to severe inflammatory acne compared to the application of adapalene alone, and that 4 weeks of the combination therapy is preferable to 2 weeks of treatment.

    Acne vulgaris, a multifactorial condition often conferring significant psychosocial morbidity, affects an estimated 40 million people in the United States. The majority of these individuals are adolescents and young adults. The pathophysiology of the condition is still not fully known, but it is believed to be related in part to excess sebum production, follicular hyperkeratinization, microbial colonization by P acnes, and inflammation. Prior to initiating treatment in a female patient, a hyperandrogenic state must be considered and ruled out through history, physical exam, and laboratory evaluation if necessary. Treatment options are vast and include hormonal therapy among others. Hormonal therapies have long been noted to reduce acne lesions and offer a valuable adjuvant to standard therapy. Hormonal agents are thought to improve acne by blocking the androgen receptor and/or decreasing circulating androgens which leads to decreased sebum production. Hormonal treatment options include spironolactone, other antiandrogens, and oral contraceptives. The use of these agents to effectively treat acne has been demonstrated in several randomized, placebo-controlled clinical trials. Optimal results are often achieved with combination therapy with the goal of targeting multiple pathogenic pathways in acne development. PMID:18656070

    Background: Treatment of acne is an important issue for reducing the cosmetic and psychological burden of disease. Regarding the inflammatory effect of LT-B4 in acne lesions and action mechanism of Montelukast, this study was performed to determine the efficacy of Montelukastin acne treatment comparison with doxycycline. Materials and Methods: In a randomized clinical trial that was performed in Dermatology Clinic in a Training Tertiary Health Care Center in Tehran, Iran since January 2012 to May 2014, 52 patients with moderate acne were evaluated. The included patients were randomly assigned to receive doxycycline 100 mg/day plus 1% Clindamycin solution (Group 1) or Montelukast 5 mg daily plus 1% clindamycin solution (Group 2). The acne severity index was measured and compared between two groups at baseline (on admission), 1-month and 3 months later. Independent-Sample-T, Chi-Square, and Repeated-Measure ANOVA tests were used and were considered statistically significant at P < 0.05. Results: The mean age was 26.8 ± 7.1 in Group 1 and25 ± 4.8 in Group 2 (P = 0.1). 73% women and 26.7% 4 men in Group 1 and 86.7% women, and 13.3% men in Group 2 (P = 0.01). The mean acne severity index at baseline was 18.2 ± 6.1 and 19 ± 4.2 in Montelukast and doxycycline group, respectively (P = 0.679). The mean acne severity index after 1-month was 10.5 ± 6.2 and 12.9 ± 3.3 in Montelukast and doxycycline group, respectively (P = 0). Finally, the mean acne severity index after 3 months follow-up was 8.6 ± 4.8 and 8.2 ± 1.2 in Montelukast and doxycycline group, respectively (P = 0.01). There was no significant difference between two groups regarding the amount of decrease in acne severity index across the study (P = 0.186). However, each groups showed a significant reduction in the acne severity index, separately (P = 0.001). Conclusion: It may be concluded that Montelukast is an effective and safe medication for moderate-level acne treatment. PMID:26109994

    There are few clinical studies which compare the efficacy and patient satisfaction for oral antibiotics to treat inflammatory acne. To clarify the difference between oral antibiotics, acne patients with moderate to severe inflammatory eruptions were randomized into three groups, and each patient was given minocycline (MINO), roxithromycin (RXM) or faropenem (FRPM) for 4 weeks, followed by 4 weeks of observation without any oral antibiotics. We estimated the reduction rate of inflammatory lesion counts, the scale of Skindex-16 which represents patient quality of life (QOL), and minimum inhibitory concentrations required to inhibit the growth of 90% of Propionibacterium acnes isolated from acne patients (MIC(90) ). In all three groups, inflammatory lesion counts, and emotional and total score of Skindex-16 were significantly improved (P<0.05) after 4 weeks treatment, and these effects were maintained for the following 4 weeks. Dizziness/nausea in two patients (4.1%) of the MINO group and diarrhea in three patients (5.9%) of the FRPM group were observed. There was no significant difference of percentage reduction in inflammatory lesion counts and incident rates of side-effects between these three oral antibiotics. MIC(90) of MINO was 0.25 μg/mL before and after treatment, but MIC(90) of RXM had increased from 0.25 μg/mL to more than 32 μg/mL after treatment. MIC(90) of FRPM was 0.06 μg/mL or less for all strains before and after treatment. Our randomized controlled clinical trial suggested that MINO, RXM and FRPM were efficient to improve inflammatory acne and patient QOL, and there was no significant difference between them.

    Background Limited data are available on acne treatment patterns, expectations, and satisfaction in the adult female subpopulation, particularly among different racial and ethnic groups. Objective Describe acne treatment patterns and expectations in adult females of different racial/ethnic groups and analyze and explore their potential effects on medication compliance and treatment satisfaction. Methods A cross-sectional, Web-based survey was administered to US females (25–45 years) with facial acne (≥25 visible lesions). Data collected included sociodemographics, self-reported clinical characteristics, acne treatment use, and treatment expectations and satisfaction. Results Three hundred twelve subjects completed the survey (mean age, 35.3±5.9 years), comprising black (30.8%), Hispanic (17.6%), Asian/other (17.3%), and white (34.3%). More than half of the subjects in each racial group recently used an acne treatment or procedure (black, 63.5%; Hispanic, 54.5%; Asian/other, 66.7%; white, 66.4%). Treatment use was predominantly over-the-counter (OTC) (47.4%) versus prescription medications (16.6%). OTC use was highest in white subjects (black, 42.7%; Hispanic, 34.5%; Asian/other, 44.4%; white, 59.8%; P<0.05). The most frequently used OTC treatments in all racial/ethnic groups were salicylic acid (SA) (34.3%) and benzoyl peroxide (BP) (32.1%). Overall, compliance with acne medications was highest in white versus black (57.0±32.4 vs 42.7±33.5 days, P>0.05), Hispanic (57.0±32.4 vs 43.2±32.9 days, P>0.05), and Asian/other (57.0±32.4 vs 46.9±37.2 days, P>0.05) subjects. Most subjects expected OTC (73.7%) and prescription (74.7%) treatments to work quickly. Fewer than half of the subjects were satisfied with OTC treatment (BP, 47.0%; SA, 43.0%), often due to skin dryness (BP, 26.3%; SA, 44.3%) and flakiness (BP, 12.3%; SA, 31.1%). No statistically significant differences were observed among racial/ethnic groups in their level of satisfaction with OTC or

    Background. Acne is a dermatosis that involves an altered sebum pattern. Objectives. (1) To evaluate if a treatment based on antibiotics (lymecycline) can alter fatty acids contents of the sebum of patients with acne; (2) to evaluate if oral supplementation of fatty acids can interfere with fatty acids contents of the sebum of patients with acne; (3) to evaluate if there is any interaction in fatty acids contents of the sebum of patients with acne when they use both antibiotics and oral supplementation of fatty acids. Methods. Forty-five male volunteers with inflammatory acne vulgaris were treated with 300 mg of lymecycline per day, with 540 mg of γ-linolenic acid, 1,200 mg of linoleic acid, and 510 mg of oleic acid per day, or with both regimens for 90 days. Every 30 days, a sample of sebum from the forehead was collected for fatty acids' chromatographic analysis. Results. Twelve fatty acids studied exhibited some kind of pattern changes during the study: C12:0, C14:0, C15:0, C16:1, C18:0, C18:1n9c+C18:1n9t, C18:2n6t, C18:3n6, C18:3n3, C20:1, C22:0, and C24:0. Conclusions. The daily administration of lymecycline and/or specific fatty acids may slightly influence some fatty acids levels present in the sebum of patients with inflammatory acne vulgaris.

  4. 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 is a chronic inflammatory human skin disease, characterized by areas of skin with seborrhoea, comedones, papules, nodules, pimples, and possibly scarring with lesions occurring on face, neck, and back. Nanotechnological approaches such as particulate (solid lipid nanoparticles and microspheres), vesicular (liposomes and niosomes), colloidal drug delivery systems (micro-emulsion and nano-emulsion), and miscellaneous systems (aerosol foams and micro-sponges) have an important place in acne therapy. These approaches have an enormous opportunity for the designing of a novel, low-dose and effective treatment systems to control acne disease. In this review, we specially focus on the different nanotechnological approaches for an effective treatment of acne. PMID:24844191

    2016-07-01

    Acne vulgaris (AV) is a common skin disease that is challenging to successfully treat due to its complex underlying pathophysiology and chronicity. Unrealistic expectations based on the desire for rapid and complete clearance or local tolerability reactions related to topical medications often lead to incomplete adherence with therapy, premature treatment cessation, and poor therapeutic outcomes. Despite stressing to patients the importance of compliance and the lag time of several weeks before visible improvement may be noted with treatments for AV, data on evaluation of the time taken to achieve a clinically meaningful improvement of AV that may be perceived by clinicians and patients are limited. Clindamycin phosphate 1.2%-benzoyl peroxide 3.75% (clindamycin-BP 3.75%) gel has been shown in pivotal trials to be effective and well tolerated in patients with moderate to severe AV. This article reviews a new concept referred to as time to onset of action (TOA), which is described in detail and illustrated using the pivotal trial data with clindamycin-BP 3.75% gel for treatment of AV.

    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.

    Objective To investigate the efficacy of Honevo, a topical 90% medical-grade kanuka honey, and 10% glycerine (honey product) as a treatment for facial acne. Design Randomised controlled trial with single blind assessment of primary outcome variable. Setting Outpatient primary care from 3 New Zealand localities. Participants Of 136 participants aged between 16 and 40 years with a diagnosis of acne and baseline Investigator's Global Assessment (IGA) for acne score of ≥2.68, participants were randomised to each treatment arm. Interventions All participants applied Protex, a triclocarban-based antibacterial soap twice daily for 12 weeks. Participants randomised to the honey product treatment arm applied this directly after washing off the antibacterial soap, twice daily for 12 weeks. Outcome measures The primary outcome was ≥2 point decrease in IGA score from baseline at 12 weeks. Secondary outcomes included mean lesion counts and changes in subject-rated acne improvement and severity at weeks 4 and 12, and withdrawals for worsening acne. Results 4/53 (7.6%) participants in the honey product group and 1/53 (1.9%) of participants in the control group had a ≥ 2 improvement in IGA score at week 12, compared with baseline, OR (95% CI) for improvement 4.2 (0.5 to 39.3), p=0.17. There were 15 and 14 participants who withdrew from the honey product group and control group, respectively. Conclusions This randomised controlled trial did not find evidence that addition of medical-grade kanuka honey in combination with 10% glycerine to standard antibacterial soap treatment is more effective than the use of antibacterial soap alone in the treatment of acne.

    In this multi-site case series, the efficacy of high intensity focused radiofrequency (RF) delivered to the dermis was evaluated for treating acne scars. A novel delivery system that uses insulated microneedles to deliver a desired thermal effect to multiple depths of the dermis while sparing the epidermis from RF injury was used. Four (4) healthy subjects from four different practices were evaluated and used in this case report. The subjects were treated between 3 or 4 times depending on the severity of the acne scars presented. The depth of thermal delivery was adjusted before each pass and all subjects received at a minimum, three passes to the treated area. Before and after photographs along with adverse effects were recorded. The theory behind the use of insulated needles with the active RF delivery at the distal tip is to allow for significant thermal injury to several layers of the dermis while avoiding thermal injury to the epidermis. This case report demonstrates significant improvement on acne scars and that all skin types should be safely treatable with minimum downtime realized. PMID:26355629

    2010-01-01

    Acne is a common disorder affecting the majority of adolescents and often extends into adulthood. The central pathophysiological feature of acne is increased androgenic stimulation and/or end-organ sensitivity of pilosebaceous units leading to sebum hypersecretion and infundibular hyperkeratinization. These events lead to Propionibacterium acnes proliferation and subsequent inflammation. Hormonal therapy, including combined oral contraceptives (OCs), can attenuate the proximate androgenic trigger of this sequence. For many women, hormonal therapy is a rational option for acne treatment as it may be useful across the spectrum of severity. Drospirenone (DRSP) is a unique progestin structurally related to spironolactone with progestogenic, antimineralocorticoid, and antiandrogenic properties. It is available in 2 combined OC preparations (30 μg EE/3 mg DRSP; Yasmin(®) in a 21/7 regimen; and 20 μg EE/3 mg DRSP; Yaz(®) in a 24/4 regimen). These preparations are bereft of the fluid retentional side effects typical of other progestins and their safety has been demonstrated in large epidemiological studies in which no increased risk of vascular thromboembolic disease or arrhythmias was observed. In acne, the efficacy of DRSP-containing OCs has been shown in placebo-controlled superiority trials and in active-comparator non-inferiority trials. PMID:21072290

    Acne is one of the most prevalent skin conditions affecting teenagers. It is a disease of the pilosebaceous unit. Blockage of sebaceous glands and colonisation with Proionobacterium acnes leads to acne. Grading the severity of acne helps to determine the appropriate treatment. Treatment of acne should be started as early as possible to minimise the risk of scarring and adverse psychological effects. It should be tailored to the individual patient, the type of acne, its severity, the patient's ability to use the treatment, and the psychological state. Topical agents are the mainstay for treatment of mild acne. Moderate acne is treated with oral antibiotics. Resistance to antibiotics may be reduced by subsequent use of non‐antibiotic topical medications. Severe acne is treated with isotretinoin, and this can lead to permanent remission. With better education and care given by medical profession, acne treatment could be significantly improved. PMID:16891439

    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

    Background: While laser resurfacing remains the most effective treatment option for atrophic acne scars, the high incidence of post-treatment adverse effects limits its use. Fractional laser photothermolysis attempts to overcome these limitations of laser resurfacing by creating microscopic zones of injury to the dermis with skip areas in between. Aim: The aim of the present study is to assess the efficacy and safety of fractional CO2 laser resurfacing in atrophic facial acne scars. Materials and Methods: Sixty patients with moderate to severe atrophic facial acne scars were treated with 3-4 sessions of fractional CO2 laser resurfacing at 6-week intervals. The therapeutic response to treatment was assessed at each follow up visit and then finally 6 months after the last laser session using a quartile grading scale. Response to treatment was labelled as ‘excellent’ if there was >50% improvement in scar appearance and texture of skin on the grading scale while 25-50% response and <25% improvement were labelled as ‘good’ and ‘poor’ response, respectively. The overall satisfaction of the patients and any adverse reactions to the treatment were also noted. Results: Most of the patients showed a combination of different morphological types of acne scars. At the time of final assessment 6 months after the last laser session, an excellent response was observed in 26 patients (43.3%) while 15 (25%) and 19 patients (31.7%) demonstrated a good and poor response respectively. Rolling and superficial boxcar scars responded the best while pitted scars responded the least to fractional laser monotherapy. The commonest reported adverse effect was transient erythema and crusting lasting for an average of 3-4 and 4-6 days, respectively while three patients developed post-inflammatory pigmentation lasting for 8-12 weeks. Conclusions: Fractional laser resurfacing as monotherapy is effective in treating acne scars especially rolling and superficial boxcar scars with minimal

    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.

    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.

    The aim of this study was to develop ethosomes loaded with cryptotanshinone (CPT) and formulate them as a topical gel for the treatment of acne. Ethosomes were prepared and evaluated for vesicle size, CPT loading and encapsulation efficiency. Optimized ethosomes were formulated as Carbomer 974 gels and compared with conventional hydroethanolic gels for transdermal permeation and skin deposition in vitro. The anti-acne activity and skin irritation of the gel was investigated in rabbits. Optimized ethosomes had an average vesicle size of 69.1 ± 1.9 nm with CPT loading and encapsulation efficiency of 0.445 ± 0.007 mg/mL and 40.31 ± 0.67%, respectively. The transdermal flux and skin deposition of the optimized ethosomal gel were 2.5- and 2.1-times those of conventional gels. The ethosomal gel revealed better anti-acne effect with only slight skin irritation. This study demonstrates that ethosomal formulation is an effective dermal delivery system for CPT, and that CPT ethosomal gels are promising future acne treatments. PMID:27441661

    2015-01-01

    Background: Acne is commonplace in adolescents and can be difficult to manage. Providing an effective and well-tolerated treatment may lead to improved adherence, increased patient satisfaction, and improved clinical outcomes. Methods: A post hoc analysis of efficacy and cutaneous tolerability in 289 adolescents (age range, 12 to <18 years) with moderate-to-severe acne who had been enrolled in a multicenter study and were randomized to receive either clindamycin phosphate 1.2%/benzoyl peroxide 3.75% gel or vehicle once daily for 12 weeks. Results: Significantly superior reductions in lesion counts were observed in the clindamycin phosphate 1.2%/benzoyl peroxide 3.75% gel group compared to vehicle from Week 4, with mean percent reductions in inflammatory and noninflammatory lesions from baseline of 59.9 percent and 50.5 percent, respectively (both P<0.001 versus vehicle). One-third of patients treated with clindamycin phosphate 1.2%/benzoyl peroxide 3.75% gel achieved ≥2-grade improvement from baseline in their Evaluator’s Global Severity Score (compared to 8.5% with vehicle, P<0.001) and 35 percent of patients reported clear or almost clear skin at Week 12 (compared to 12.8% with vehicle, P<0.001). Cutaneous tolerability was excellent with all mean scores ≤0.2 at Week 12 (where 1=mild). Conclusions: Clindamycin phosphate 1.2%/benzoyl peroxide 3.75% gel is an effective, safe, well-tolerated treatment for adolescents with moderate-to-severe acne. PMID:26029332

    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

    This review focuses on the subject of acne in women, a disease that is increasingly common and that can also affect men. Adult acne differs from the type of acne that occurs in teenagers, and it may persist beyond adolescence or have its onset at an older age (adult-onset acne or late acne). Acne can have a negative impact on the quality of life of patients at any age, leading to a negative body image and decrease in self-esteem, and in older patients it can result in discrimination in the workplace and in other social environments. Acne in women must be understood as a specific problem, and here we discuss the pathogenesis, clinical presentation, psychology and treatment of this very prevalent problem. PMID:25597414

    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.

    Introduction: There is a paucity of studies on the use of chemical peels for acne scars among the Asian population. A trichloroacetic acid (TCA) and Jessner's combination chemical peel, originally described by Monheit, is said to be better than a TCA peel alone. Aims: The aim of the study was to compare the efficacy of 20% TCA and Jessner's solution versus 20% TCA alone for the treatment of acne scars. Materials and Methods : The patients were divided into two groups of 25 patients each. Chemical peeling was done in both the groups. In Group I, chemical peeling with Jessner's peel followed by 20% TCA was done and in Group II patients chemical peeling with 20% TCA peel alone was done. Results: In Group I (Jessner's peel and 20% TCA), mild improvement of acne scars was seen in 8% cases, moderate improvement in 32% cases and marked improvement of acne scars was seen in 60% patients. In Group II (20% TCA), mild improvement of acne scars was seen in 32% cases, moderate improvement in 40% cases and marked improvement of acne scars was seen in 28% patients. But, the difference in improvement of acne scars was not statistically significant in both the groups (P value > 0.05). PMID:25949022

    There is limited information available regarding patient preferences and attributes of topical product formulations for specific dermatologic conditions. This study focused on product attributes that were most desirable for 3 dermatologic conditions: acne, atopic dermatitis (AD), and plaque psoriasis (PP). Six focus groups were conducted with participants self-reporting 1 of these conditions and use of 2 or more topical treatments. Discussion focused on symptoms, treatments tried, and vehicle attributes. Fifty-four subjects participated: acne, n=19; AD, n=18; and PP, n=17. The most commonly reported prescription medication vehicles were creams and ointments, followed by lotions, gels, and foams. Itching and redness were the only symptoms spontaneously reported across all 6 focus groups. The attributes considered most important across all conditions included: moisturizing, absorbs/disappears/dries quickly, available in various formulations, does not bleach or stain skin/hair/clothing, is not greasy or oily, is not sticky or tacky, is long lasting/long acting, is fragrance or odor free, is easy to apply/simple to use, and can use all the time. Preferences attributable to acne included: easy to dispense/dispenses right amount, nondrying, product goes on/spreads smoothly, container is not easily broken/does not leak, and creamy. Preferences attributable to AD included: not noticeable to others/conceals area, good consistency, and cooling. Patient preference for product vehicle is relevant to adherence as compliance is a major factor for high rates of failure for dermatologic treatments. PMID:25101344

    Acne scars are common and stigmatizing for the affected patients. Besides surgery, chemical peels, microdermabrasion, and microneedling, the treatment with fractional laser is a standard therapy. The results of reducing acne scars treated either with a fractional Er:YAG (erbium-doped yttrium-aluminum-garnet [Er:Y3Al5O1]) or a carbon dioxide (CO 2 ) laser at different wavelengths were compared and evaluated in the pilot study presented here. Fourteen patients with severe scars on both cheeks were treated four times in a random split-face approach: on one side with Er:YAG laser and on the contralateral side with CO2 laser following a standardized protocol. Therapeutic success was evaluated through the use of a high-resolution, 3D small-field capture system (PRIMOS), digital photography, and the Patient and Observer Scar Assessment Scale (POSAS) questionnaire. The evaluation was performed by a blinded investigator. Treatment results displayed a higher efficacy of the fractional CO2 laser compared with the Er:YAG laser as displayed by digital photographs. Additionally, objective (high-resolution, 3D small-field capture; PRIMOS) and subjective (POSAS) measuring results correlated positively in certain qualities (color, stiffness, thickness, surface, overall opinion). Using a novel scientific approach, we evaluated the therapeutic efficacy of different fractional lasers on acne scars using a rater-blinded approach. Compared with an Er:YAG laser, better skin smoothening was achieved by fractional CO2 laser treatment. PMID:26579867

    Background and objectives: Most people who experience the acne suffer from damage under the surface of their skin which causes saucer-like depressions or pits on their skin. Sometimes the skin loses its underlying support and develops fibrous bands of tissue between the skin and subcutaneous layer, which pull on the epidermis and cause a wavy texture called as rolling scar. Treatment of acne scars is a therapeutic challenge that may require multiple modalities. Subcision is a procedure that has been reported as a beneficial method in the treatment of rolling acne scars. Although Subcision is a valuable method, its efficacy is mild to moderate because of the high recurrence rate and patients dissatisfaction due to some side effects include post procedure inflammation. Materials and methods: This pilot study is a clinical trial. The 8 patients suffered from mild to severe rolling acne scars on their face with symmetrical distribution of lesions, underwent Subcision with the Cannula No 18 and 21 and followed-up for 3 months. Outcomes of Subcision procedures were assessed by 3 board certified dermatologists (blind) after 2 session of treatment. The patients’ satisfaction was considered to compare with dermatologist’s opinions. The degree of improvement and satisfaction of the treatment estimated with these points: poor: 0, fine: 1-3, good: 4-6, and very good: 7-9. The data were finally analyzed with SPSS-18 software. Results: Subcision with the Cannula showed good and very good improvement in about 88% of patient with a satisfaction good and very good improvement in all of patients (100%). Assessment of photographic data showed 100% improvement in scar depth, topography and overall appearance of acne scars. The average numbers of lesions before the treatment were 24.8 ± 12.1 and after treatment it was reduced to 12.8 ± 2.1 (p<0.05). Conclusion: Subcision with the Cannula appears to be a safe method with high efficacy in the treatment and high satisfaction in

    Objectives The Acne Priority Setting Partnership (PSP) was set up to identify and rank treatment uncertainties by bringing together people with acne, and professionals providing care within and beyond the National Health Service (NHS). Setting The UK with international participation. Participants Teenagers and adults with acne, parents, partners, nurses, clinicians, pharmacists, private practitioners. Methods Treatment uncertainties were collected via separate online harvesting surveys, embedded within the PSP website, for patients and professionals. A wide variety of approaches were used to promote the surveys to stakeholder groups with a particular emphasis on teenagers and young adults. Survey submissions were collated using keywords and verified as uncertainties by appraising existing evidence. The 30 most popular themes were ranked via weighted scores from an online vote. At a priority setting workshop, patients and professionals discussed the 18 highest-scoring questions from the vote, and reached consensus on the top 10. Results In the harvesting survey, 2310 people, including 652 professionals and 1456 patients (58% aged 24 y or younger), made submissions containing at least one research question. After checking for relevance and rephrasing, a total of 6255 questions were collated into themes. Valid votes ranking the 30 most common themes were obtained from 2807 participants. The top 10 uncertainties prioritised at the workshop were largely focused on management strategies, optimum use of common prescription medications and the role of non-drug based interventions. More female than male patients took part in the harvesting surveys and vote. A wider range of uncertainties were provided by patients compared to professionals. Conclusions Engaging teenagers and young adults in priority setting is achievable using a variety of promotional methods. The top 10 uncertainties reveal an extensive knowledge gap about widely used interventions and the relative merits

    Acne affects more than 40 million people, of which more than half are women older than 25 years of age. These women frequently fail traditional therapy and have high relapse rates even after isotretinoin. Recent advances in research have helped to delineate the important role hormones play in the pathogenesis of acne. Androgens such as dihydrotestosterone and testosterone, the adrenal precursor dehydroepiandrosterone sulfate, estrogens, growth hormone, and insulin-like growth factors may all contribute to the development of acne. Hormonal therapy remains an important part of the arsenal of acne treatments available to the clinician. Women dealing with acne, even those without increased serum androgens, may benefit from hormonal treatments. The mainstays of hormonal therapy include oral contraceptives and antiandrogens such as spironolactone, cyproterone acetate, or flutamide. In this article, we discuss the effects of hormones on the pathogenesis of acne, evaluation of women with suspected endocrine abnormalities, and the myriad of treatment options available.

    Background and Objectives: Post-acne scarring is a common and well-known sequelae of acne vulgaris. We aim to study the impact of post-acne scarring on the quality of life (QOL) among young adults in Singapore. Settings and Design: This was a non-interventional prospective study. Materials and Methods: Patients aged 21-40 years with atrophic and hypertrophic acne scars who attended the National Skin Centre, Singapore were recruited in the study. They answered a simple questionnaire and the clinical severity of their acne scars were assessed by the doctor. Statistical Analysis Used: Descriptive analyses using absolute and percentage frequencies were performed on all data. The test of significance was two-sided and was set at 5% (P ≤ 0.05). Differential analyses were conducted using the parametric, independent two-sample t-test and non-parametric Mann–Whitney U-test. The statistical assessments were performed using SPSS version 18.0. Results: A total of 100 patients were studied. The mean patients’ subjective self-scoring on the severity of their post-acne scars was 5.78/10 and the mean Dermatology Life Quality Index (DLQI) for post-acne scars was 5.61. Many (36%, n = 36) were self-conscious of their acne scars and 24%, (n = 24) felt that their acne scars was affecting their social activities. Conclusions: Our study showed that post-acne scars have a significant negative effect on the QOL of young adults. It highlights the need to increase public awareness of acne vulgaris and its sequelae through education programs and advocating early treatment to reduce the risk of scarring. PMID:26644739

    Acne is a common and complex skin disease, with a very complex pathogenesis. Although in women the relationship between acne and insulin resistance is well known, in particular in women with PCOS, in males this relationship has been poorly investigated. In total, 20 subjects with an altered metabolic profile were considered for this study and randomized as follows: 10 patients were treated with metformin plus a hypocaloric diet for 6 months (group A), while 10 patients did not receive any treatment with metformin and were only followed up (group B). All patients of group A, after 6 months of metformin therapy, had a statistically significant improvement compared with patients in group B. Our study reveals the importance of diet and insulin resistance in acne pathogenesis, and underlines the possible use of metformin and diet as possible adjuvant therapy for male patients with acne.

    Objective: To investigate the cutaneous safety and tolerability of clindamycin phosphate 1.2%/benzoyl peroxide 3.75% gel in moderate-to-severe acne patients. Methods: A safety assessment of 498 patients with moderate-to-severe acne receiving clindamycin phosphate 1.2%/benzoyl peroxide 3.75% gel or vehicle for 12 weeks. Results: The vast majority (80-95%) of patients reported no cutaneous safety or tolerability problems throughout the study. Mean scores for both active and vehicle were all <1 (where l=mild) and reduced over the duration of the study. When scaling, erythema, itching, burning, or stinging was reported it was generally mild. Moderate or severe reactions to clindamycin phosphate 1.2%/benzoyl peroxide 3.75% gel were rare and generally seen early in treatment. There were eight reports (3.3%) of moderate erythema, four reports (1.7%) of moderate scaling, three reports (1.2%) of moderate itching, and one report of moderate burning (0.4%) at Week 4. There was one report (0.4%) of severe erythema and one report (0.4%) of severe burning (both at Week 4), with one report (0.4%) of severe stinging at Week 12. There were no substantive differences seen in cutaneous tolerability among treatment groups and younger patients tended to have milder reactions. Limitations: It is not possible to determine the contributions of the individual active ingredients. Conclusion: Clindamycin phosphate 1.2%/benzoyl peroxide 3.75% gel has a favorable safety and tolerability profile with very low incidence of moderate or severe reactions. PMID:26345297

    Several treatment modalities are used for the treatment of acne scars with variable results. Recent studies showed that fractional radiofrequency may be an effective treatment modality for acne scars. The objective of this study was to assess the efficacy, safety, tolerability and patient satisfaction of fractional bipolar radiofrequency (RF), the eTwo™ system (Syneron Candela Ltd., Yokneam, Israel) for treating acne scars. Twelve patients with moderate to severe acne scars received 3-5 treatments with the Sublative fractionated bipolar RF applicator of the eTwo device at 1-month intervals. Patients were evaluated clinically and photographically at each visit and 3 months after the final treatment. Very good improvement (at least one scale) was seen after completing the five treatments. The patient satisfaction survey (Global Aesthetic Improvement Scale scores) revealed that half (6 out of 12) of the patients reported to be satisfied with treatment results, while the other half reported to be very satisfied. Beyond the expected erythema and minimal scab formation in the treated areas, which was mild and transient, none of the participants reported any adverse events. The data presented here support the high efficacy and safety of fractionated bipolar RF for the aesthetic improvement of moderate to severe acne scars. PMID:26279170

    Acne inversa (AI) is a disabilitating chronic inflammatory disease with major negative impact on quality of life and significant co-morbidities. This is an important link to insights into immune dysfunction, which stimulated therapeutic approaches like tumor necrosis-α inhibitor therapy. This new off-label drug treatment is particularly beneficial when used in combination with wide excision of inflamed skin and subcutaneous tissue. Retinoids have been reported to be helpful in secondary prevention. The standard of therapy in advanced cases is surgery with wide excisions and healing by secondary intention. This treatment results in significant reduction of complaints and achieves satisfactory body contouring. PMID:23439959

    Three patients with chronic osteoma cutis secondary to acne vulgaris were treated with the dermabrasion-Loo-punch-excision technique. Under regional nerve block with lidocaine-bipuvacaine (50:50) a uniform dermabrasion was performed across the entire face, including the hairline and 1 cm below the jawline. This exposed the foci of osteoma cutis. Then the appropriate sized Loo punch (usually the 2.0- or the 2.5-mm punch) was used to excise the bluish-gray miliary lesions. The majority of the foci were removed in one operation. Following excision, the lesions were closed with 7-0 prolene suture. To prevent crust formation postoperatively, Aloe-vera-soaked polyethylene oxide gel dressings (Vigilon) were changed twice daily following an ice water compress. Sutures were removed rapidly in 5 to 7 days to prevent the appearance of suture lines. Although one patient required an additional procedure, the cosmetic results were excellent. Only a few small residual blue "dot" lesions remained in these three cases. PMID:2953769

    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

    Post-inflammatory erythema is a common result of acne inflammation and is cosmetically unacceptable without effective treatment. Fractional microneedling radiofrequency (FMR) has potential for treatment of post-inflammatory erythema. The aim of this study was to evaluate the efficacy and safety of this treatment. A retrospective chart review was undertaken of 25 patients treated with 2 sessions of radiofrequency at 4-week intervals and 27 patients treated with oral antibiotics and/or topical agents. Efficacy was assessed through an investigator's global assessment of photographs, and the analysis of erythema with image analysis software and photometric devices. Histological changes resulting from the treatment were evaluated by skin biopsy. FMR treatment resulted in significant improvements in erythema with no severe adverse effects. Histological study revealed a reduction in vascular markers and inflammation. FMR is a safe and effective treatment for post-inflammatory erythema, with potential anti-inflammatory and anti-angiogenetic properties. PMID:26059315

    In the given research the new method of fluorescent diagnostics (FD) and photodynamic therapy (PDT) control of acne disease is submitted. Method is based on simultaneous diagnostics in natural and fluorescent light. PDT was based on using 5-ALA (5- aminolevulinic acid) preparation and 600-730 nanometers radiation. If the examined site of a skin possessed a high endogenous porphyrin fluorescence level, PDT was carried out without 5-ALA. For FD and treatment control a dot spectroscopy and the fluorescent imaging of the affected skin were used.

    Hormones, in particular androgen hormones, are the main cause of acne in men, women, children and adults, in both normal states and endocrine disorders. Therefore, the use of hormonal therapies in acne is rational in concept and gratifying in practice. Although non-hormonal therapies enjoy wide usage and continue to be developed, there is a solid place for hormonal approaches in women with acne, especially adult women with persistent acne. This review covers the physiological basis for hormonal influence in acne, the treatments that are in use today and those that show promise for the future. The main treatments to be discussed are oral contraceptives androgen receptor blockers like spironolactone and flutamide, inhibitors of the enzyme 5 alpha-reductase and topical hormonal treatments.

    Background Scarring is a very common complication of severe acne and is difficult to treat by conventional methods. 5-Aminolevulinic acid (ALA) photodynamic therapy (PDT) is a novel treatment for improving acne lesions. Fractional laser resurfacing is a promising treatment for scar treatment because of its unique ability to stimulate the wound healing response and its depth of penetration. Objective To evaluate the efficacy of combination therapies of ALA-PDT and ablative fractional Er:YAG laser (2,940 nm) for scarring lesions in severe acne patients. Methods A prospective, single-arm, pilot study. Forty subjects with severe acne were treated with 15% ALA-PDT for four times at 10-day intervals. They then received ablative fractional Er:YAG laser treatment five times at 4-week intervals. Three independent investigators evaluated subject outcomes at 1, 3, 6, and 12 months post-treatment (primary outcome); patients also provided self-assessments of improvement (secondary outcome). Results Significant reductions in acne score (P<0.01) were obtained at follow-up visits after 1, 3, 6, and 12 months. After 6 month, the lesions showed overall improvement in all of subjects (good to excellent in acne inflammatory lesions), 80% overall improvement in acne scars. After 12 months, most of subjects had improved hypertrophic/atrophic scars (good to excellent in 85%) and no one had recurrent acne inflammatory lesions. Patient self-evaluation also revealed good to excellent improvements (on average) in acne lesions and scarring, with significant improvements in self-esteem after 6 months post-treatment. Conclusions PDT can control the inflammation and improve the severity of acne lesions. Fractional resurfacing is a promising new treatment modality for scars by stimulating wound healing and remodeling. The combination therapy is a promising option for severe acne to prevent and improve car formation. PMID:24391075

    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

    Acne in the adult female often presents as a chronic condition that can have a considerable negative psychological, social and emotional impact on the affected individual. Estimated prevalence rates of adult female acne vary widely according to study type. Case reports and clinical examinations estimate the prevalence of clinical acne at 10-12%, while survey estimates of physiological disease states are as high as 54%. Two subtypes of adult female acne may be defined according to time of onset: 'persistent' and 'late-onset', accounting for approximately 80 and 20% of cases, respectively. Postadolescent acne is generally mild-to-moderate in severity and presents with more inflammatory lesions and fewer comedones compared to adolescent acne. Furthermore, the impact of acne on the quality of life is often greater in adult females than in younger individuals. Despite these important differences, the key principles of acne treatment in the adult female do not differ significantly from those of other age groups. However, specific characteristics relating to the adult female should be considered when selecting a treatment regimen. PMID:24280643

    Acne vu lgaris is a multifactorial inflammatory skin disease causing social stigma and psychological effect on patients. We hypothesized that the genes that can affect both lipid metabolism and inflammation may be central for acne formation and present targets for treatment. Pro-inflammatory adipokine resistin, one such likely target, activates NFkB and JNK pathways inducing TLR-2, IL-1, IL-6, and TNFα genes. The polymorphisms in promoter and intron region of the resistin gene affect its expression levels. Therefore, we explored the association of resistin polymorphisms (RETN +299G > A and -420C > G) with pathogenesis of acne vulgaris. We used PCR-RFLP method to genotype at the two single nucleotide polymorphisms at RETN promoter in 530 acne patients vs. 550 age- and sex-matched control subjects. We also measured serum lipid levels in acne patients and associated these with RETN genotypes. We found that the RETN gene polymorphisms are strongly associated with acne vulgaris and the severity of acne symptoms. In females the variant allele frequencies of both SNPs are statistically higher in patients than in controls; in males frequency distribution does not reach significance. The haplotype containing both variant alleles is significantly more common in patients than in controls. We find no association of RETN SNPs with the acne types. Importantly, we found that the levels of HDL-C were significantly decreased in variant genotype of RETN. Our results show that the RETN polymorphisms expected to boost resistin expression increase the risk of developing acne. We suggest that resistin may provide an attractive target for treatment.

    The aim of this work was to optimize polymeric nano-sized micellar carriers of the anti-acne compound benzoyl peroxide (BPO) and to examine the ability of these carriers to deposit into hair follicles with the objective of improving skin delivery of BPO. BPO loaded polymeric micelles composed of Pluronic(®) F127 were prepared by the thin film hydration method and characterized in terms of size, loading capacity, morphology and physical stability. The optimized micelle formulation was then selected for skin delivery studies. The penetration of BPO loaded micellar carriers into skin and skin appendages across full thickness porcine skin was examined in vitro. Confocal microscopy images confirmed the penetration of Nile Red into hair follicles, which was loaded into micellar carriers as a model fluorescent compound. The relative safety of the polymeric micelles was evaluated with the MTT viability test using mouse embryonic fibroblasts. The results indicated that nano-sized polymeric micelles of BPO composed of Pluronic(®) F127 offer a potential approach to enhance skin delivery of BPO and that targeting of micelles into hair follicles may be an effective and safe acne treatment.

    Propionibacterium acnes is a Gram-positive commensal bacterium thought to be involved in the pathogenesis of acne vulgaris. Although the ability of P. acnes in the initiation of pro-inflammatory responses is well documented, little is known about adaptive immune responses to this bacterium. The observation that infiltrating immune cells consist mainly of CD4(+) T cells in the perifollicular space of early acne lesions suggests that helper T cells may be involved in immune responses caused by the intra-follicular colonization of P. acnes. A recent report showing that P. acnes can induce IL-17 production by T cells suggests that acne might be a T helper type 17 (Th17)-mediated disease. In line with this, we show in this work that, in addition to IL-17A, both Th1 and Th17 effector cytokines, transcription factors, and chemokine receptors are strongly upregulated in acne lesions. Furthermore, we found that, in addition to Th17, P. acnes can promote mixed Th17/Th1 responses by inducing the concomitant secretion of IL-17A and IFN-γ from specific CD4(+) T cells in vitro. Finally, we show that both P. acnes-specific Th17 and Th17/Th1 cells can be found in the peripheral blood of patients suffering from acne and, at lower frequencies, in healthy individuals. We therefore identified P. acnes-responding Th17/Th1 cells as, to our knowledge, a previously unreported CD4(+) subpopulation involved in inflammatory acne. PMID:25010142

    Background: Pemphigus is a group of autoimmune blistering diseases of the skin and mucous membranes caused by the presence of antibodies against adhesion molecules on the cell surface of keratinocytes. The possible role of herpes simplex virus infection in the pathogenesis of pemphigus vulgaris (PV) has been suggested. In this study, we evaluated the impact of a course of acyclovir in improvement of the pemphigus patients and reduction of the hospitalization duration. Materials and Methods: A total of 30 patients with definitive diagnosis of PV were recruited in study. They were randomized in two groups. One group received routine treatment and another received the routine plus 2 week course of oral acyclovir (1200 mg/day). The improvement was defined as a more than 50% change in baseline severity score of the disease. All data was registered at the checklists and after follow-up period, the statistical analyses were performed by aid of t-test and Fisher's exact test. Results: There was no statistically significant difference in mean severity score and improvement rates between two groups at the end of study (P > 0.05). Meanwhile, there was no statistical difference in duration of hospitalization in two groups (P > 0.05) though the severity score and hospitalization duration were apparently less in acyclovir-group than control group. Neither of the patients (in acyclovir group) showed any side effect. Conclusion: We did not observe any difference between response to treatment and hospitalization period in the group that was treated with acyclovir as compared with control group. However, the partial and complete remissions were higher in patients on acyclovir therapy compared to controls. In those pemphigus patients who do not respond to sufficient immunosuppressive regimen or show a sudden relapse after reaching partial or complete clinical remission, a trial of oral acyclovir therapy may have promising result.

    Topical dapsone 5% gel for the treatment of mild to moderate acne has been shown to be effective in randomized controlled studies. A total of 101 adult women with mild to moderate facial inflammatory acne participated in a 12-week cohort study to evaluate the efficacy, tolerability, and safety of dapsone gel 5% in this specific group who often complain of sensitive skin. The women were instructed to apply dapsone 5% gel twice daily after washing their face with a standard noncomedogenic soap-free cleanser. Treatment outcome was evaluated using physician-scored Global Acne Assessment Scale (GAAS) and patient-reported facial skin condition. Ninety-three women completed the study (6 were lost to follow-up and 2 had mild skin irritation). At 12 weeks, significant physician GAAS scores (t55 = 8.85, P = .001) and patient-reported lesion reductions were shown. Treatment success (GAAS 0 or 1) at 12 weeks was achieved in 69.4% (n = 75) of women (t94 = 4.17, P = .001), improving patient-reported quality-of-life aspects. Topical dapsone gel 5% was shown to be safe, minimally irritating, and effective in the treatment of mild to moderate inflammatory facial acne in adult women with sensitive skin. PMID:24720080

    Background. Photodynamic therapy (PDT) has been used for acne, with various combinations of photosensitizers and light sources. Objective. We evaluated the effectiveness and safety of indocyanine green (ICG) and intense pulsed light (IPL) in the treatment of acne. Materials and Methods. A total of 1,213 patients with facial acne were retrospectively reviewed. Patients received three or five treatments of ICG and IPL at two-week intervals. Clinical response to treatment was assessed by comparing pre- and posttreatment clinical photographs and patient satisfaction scores. Results. Marked to excellent improvement was noted in 483 of 1,213 (39.8%) patients, while minimal to moderate improvement was achieved in the remaining 730 (60.2%) patients. Patient satisfaction scores revealed that 197 (16.3%) of 1,213 patients were highly satisfied, 887 (73.1%) were somewhat satisfied, and 129 (10.6%) were unsatisfied. There were no significant side effects. Conclusion. These results suggest that PDT with ICG and IPL can be effectively and safely used in the treatment of acne. PMID:26558274

    The objective of this study was to study the effect of formulation compositions on physicochemical properties and anti-Propionibacterium acnes activity of film-forming solutions containing alpha-mangostin-rich extract (AM). 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. PMID:24327275

    While radiofrequency has been used medically for decades to treat a wide variety of conditions, its use therapeutically to target conditions affecting the skin is relatively new. With the development of fractional radiofrequency, which allows for the heat energy to be delivered in a more targeted manner through the use of needles as electrodes, this technique is now the preferred medical treatment option for many skin conditions given the reduction in recovery time and fewer number of reported side effects. The current study examined the clinical effectiveness of SmartScan(TM) Nano-Fractional RFTM treatment. Participants included 12 healthy female volunteers who reported varying degrees of rhytides, hyperpigmentation, or acne redness. Participants each received one treatment of SmartScan Nano-Fractional RF. The areas receiving treatment were photographed in a standardized way, using high-resolution macrophotography, at baseline (prior to receiving the treatment) and one month after treatment. Baseline and post-treatment photographs were then visually compared for treatment effects and analyzed through software-assisted quantification of variation in pigmentation and skin texture. The results indicated that this SmartScan technique for Nano-Fractional RF is effective in improving skin texture, and pigmentation. PMID:26580880

    2016-06-01

    The traditional disease model of acne has been one of follicular plugging due to 'sticky epithelial cells' associated with increased sebum production with deep follicular anaerobic conditions favoring P. acnes- generated inflammation. P. acnes biofilms have been found more frequently in patients with acne than controls. Biofilms are genetically coded to create adhesion to the pilosebaceous unit followed by production of a mucopolysaccharide coating capable of binding to lipid surfaces. Traditional therapies for acne have involved mixtures of oral and topical antibiotics admixed with topical keratolytics and retinoids, which are aimed at traditional bacterial reduction as well as downregulating the inflammatory cascade. These approaches are limited by side effect and compliance/tolerability issues. As the P. acnes biofilm may, in fact, be the instigator of this process, we studied the use of a topical agent designed to reduce the P. acnes biofilm to see if reducing the biofilm would be therapeutically efficacious. We present data of a proprietary topical non-prescription agent with a novel pharmaco mechanism designed to attack the biofilm produced by P. acnes. Our data shows a decrease of inflammatory lesions by 44% and non-inflammatory lesions by 32% after 12 weeks and also provided for a meaningful improvement in the quality of life of the patients in the study. These improvements were achieved with a product that was not associated with burning, chafing, irritation, or erythema, which can be seen with topical treatments. It is apparent from this study that by addressing the biofilm which protects the P. acnes bacteria through the use of the Acne Gel, the incidence of acne symptoms can be greatly reduced, while having no negative impacts on the patients' skin (ClinicalTrials.gov registry number NCT02404285).

    Acne keloidalis nuchae (AKN) is a chronic inflammatory condition that leads to fibrotic plaques, papules and alopecia on the occiput and/or nape of the neck. Traditional medical management focuses on prevention, utilization of oral and topical antibiotics, and intralesional steroids in order to decrease inflammation and secondary infections. Unfortunately, therapy may require months of treatment to achieve incomplete results and recurrences are common. Surgical approach to treatment of lesions is invasive, may require general anesthesia and requires more time to recover. Light and laser therapies offer an alternative treatment for AKN. The present study systematically reviews the currently available literature on the treatment of AKN. While all modalities are discussed, light and laser therapy is emphasized due to its relatively unknown role in clinical management of AKN. The most studied modalities in the literature were the 1064-nm neodymium-doped yttrium aluminum garnet laser, 810-nm diode laser, and CO2 laser, which allow for 82-95% improvement in 1-5 sessions. Moreover, side effects were minimal with transient erythema and mild burning being the most common. Overall, further larger-scale randomized head to head control trials are needed to determine optimal treatments. PMID:27432170

    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. PMID:25647437

    Ataxia-Telangiectasia is a rare multisystem autosomal recessive disorder [OMIM 208900], caused by mutations in Ataxia-Telangiectasia Mutated gene. It is characterized by neurological, immunological and cutaneous involvement. Granulomas have been previously reported in Ataxia-Telangiectasia patients, even if acne rosacea has not been described.We report a case of a young Ataxia-Telangiectasia patient with a severe immunological and neurological involvement, who developed granulomatous skin lesions diagnosed by skin biopsy as acne rosacea. Considering the severe clinical picture and the lack of improvement to multiple topic and systemic therapies, treatment with Isotretinoin was started and the skin lesions disappeared after five months. However the therapy was stopped due to drug-hepatotoxicity.Systemic treatment with Isotretinoin should be carefully considered in patient with Ataxia-Telangiectasia for the treatment of multi-drug resistant acne rosacea, however its toxicity may limit long-term use and the risk/benefit ratio of the treatment should be evaluated.

    Background: Despite advances in acne therapy in recent years, treatment failure is common. Isotretinoin is the only drug that affects almost all factors in acne pathogenesis, but side-effects are common at the doses reported in published studies in the literature. The aim of this study was to investigate the efficacy of low daily dose isotretinoin in moderate to severe acne patients. The secondary objective was to measure the rate of relapse 5 years after the completion of therapy. Materials and Methods: In this retrospective, noncomparative study, 146 patients with moderate to severe scare prone acne. Treatment regimen consisted of isotretinoin, fixed 20 mg daily, and duration of treatment-based on the weight of patient, until total cumulative dose of 120 mg/kg of body weight is achieved. No topical or other systemic therapy was allowed during the trial. Liver function tests (serum glutamic-oxalocetic transaminase, serum glutamate pyruvate transaminase, direct and total bilirubin), and lipid profiles (total cholesterol, low-density lipoprotein, high-density lipoprotein, triglyceride) were evaluated for all patients, before the initiation of treatment and again after the 2nd month of treatment. All data analyzed by Microsoft Office Excel 2007; in descriptive statics frequency and SPSS.18 software. Results: At the end of treatment course, (96.4%) demonstrated complete clearing of their acne, defined as no acne or occasional isolated lesions. In 5-year follow-up, relapse accrued in 11 (7.9%) of patients. All adverse effects were mild, and discontinuation of treatment was not necessary. Conclusion: Low dose isotretinoin was found to be a safe and effective choice for patients with moderate to severe scar prone acne vulgaris. PMID:24804178

  1. Strain-Level Differences in Porphyrin Production and Regulation in Propionibacterium acnes Elucidate Disease Associations.

    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.

    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.

    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

    Hidradenitis suppurativa/acne inversa (HS) is a chronic, inflammatory, recurrent, debilitating skin disease of the hair follicle that usually presents after puberty with painful, deep-seated, inflamed lesions in the apocrine gland-bearing areas of the body, most commonly the axillae, inguinal and anogenital regions. A mean disease incidence of 6.0 per 100,000 person-years and an average prevalence of 1% has been reported in Europe. HS has the highest impact on patients' quality of life among all assessed dermatological diseases. HS is associated with a variety of concomitant and secondary diseases, such as obesity, metabolic syndrome, inflammatory bowel disease, e.g. Crohn's disease, spondyloarthropathy, follicular occlusion syndrome and other hyperergic diseases. The central pathogenic event in HS is believed to be the occlusion of the upper part of the hair follicle leading to a perifollicular lympho-histiocytic inflammation. A highly significant association between the prevalence of HS and current smoking (Odds ratio 12.55) and overweight (Odds ratio 1.1 for each body mass index unit) has been documented. The European S1 HS guideline suggests that the disease should be treated based on its individual subjective impact and objective severity. Locally recurring lesions can be treated by classical surgery or LASER techniques, whereas medical treatment either as monotherapy or in combination with radical surgery is more appropriate for widely spread lesions. Medical therapy may include antibiotics (clindamycin plus rifampicine, tetracyclines), acitretin and biologics (adalimumab, infliximab). A Hurley severity grade-relevant treatment of HS is recommended by the expert group following a treatment algorithm. Adjuvant measurements, such as pain management, treatment of superinfections, weight loss and tobacco abstinence have to be considered. PMID:25640693

    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

    The term acne mechanica designates local exacerbations due to pressure, friction, rubbing, squeezing, or stretching. Examples are given of various physical traumata that provoke lesions in acne patients. The precipitating causes of stress are diverse, they include articles of clothing (tight straps and belts), recreational accouterments (football shoulder pads), or occupational pressure (rubbing of back in truck drivers). Sealing acne-bearing skin under adhesive for two weeks regularly induced new inflammatory lesions, which derived from the rupture of microcomedones that are not visible to the naked eye. PMID:123732

    Purpose. Macrophages serve as sweepers of microbes and inflammation-derived wastes and regulators of inflammation. Some traditional Japanese medicines are reported to have adjuvant effects by modifying macrophages. Our aim was to characterize the actions of jumihaidokuto (JHT) for treatment of skin inflammations including acne vulgaris, in which Propionibacterium acnes has pathogenic roles. Methods. Dermatitis was induced in rat ears by intradermal injection of P. acnes. JHT or prednisolone (PDN) was given orally, and ear thickness and histology were evaluated. The effects of constituents and metabolites of JHT on monocytes were tested by cell-based assays using the human monocytic THP-1 cell. Results. JHT and PDN suppressed the ear thickness induced by P. acnes injection. Histological examinations revealed that JHT, but not PDN, promoted macrophage accumulation at 24 h after the injection. PDN suppressed the macrophage chemokine MCP-1 in the inflamed ears, while JHT did not affect it. The JHT constituents liquiritigenin and isoliquiritin increased expression of CD86 (type-1 macrophage marker) and CD192 (MCP-1 receptor) and enhanced phagocytosis by THP-1. Conclusions. JHT suppressed dermatitis, probably by enhancing type-1 macrophage functions, with an action different from PDN. JHT may be a beneficial drug in treatment of skin inflammation induced by P. acnes.

    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

    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.

    Food waste contains large amount of organic matter that may be troublesome for handing, storage and transportation. A microbial fuel cell (MFC) was successfully constructed with different inoculum densities of Chlorella vulgaris for promoting food waste treatment. Maximum COD removal efficiency was registered with 44% and 25 g CODL(-1)d(-1) of substrate degradation rate when inoculated with the optimal initial density (150 mg L(-1)) of C. vulgaris, which were 2.9 times and 3.1 times higher than that of the abiotic cathode. With the optimum inoculum density of C. vulgaris, the highest open circuit voltage, working voltage and power density of MFC were 260 mV, 170 mV and 19151 mW m(-3), respectively. Besides the high biodiesel quality, promoted by MFC stimulation the biomass productivity and highest total lipid content of C. vulgaris were 207 mg L(-1)d(-1) and 31%, which were roughly 2.7 times and 1.2 times higher than the control group.

    Strongylus vulgaris is the most pathogenic helminth parasite of horses, causing verminous endarteritis with thromboembolism and infarction. A serum enzyme-linked immunosorbent assay (ELISA) has been validated for detection of antibodies to an antigen produced by migrating larvae of this parasite. The aim was to evaluate ELISA responses to anthelmintic treatment in cohorts of naturally infected horses. Fifteen healthy horses harboring patent S. vulgaris infections were turned out for communal grazing in May 2013 (day 0). On day 55, horses were ranked according to ELISA titers and randomly allocated to the following three groups: no treatment followed by placebo pellets daily; ivermectin on day 60 followed by placebo pellets daily; or ivermectin on day 60 followed by daily pyrantel tartrate. Fecal and serum samples were collected at ∼28-day intervals until study termination on day 231. Increased ELISA values were observed for the first 53 days following ivermectin treatment. Titers were significantly reduced 80 days after ivermectin treatment. Horses receiving daily pyrantel tartrate maintained lower ELISA values from 137 days post ivermectin treatment until trial termination. These results illustrate that a positive ELISA result is indicative of either current or prior exposure to larval S. vulgaris infection within the previous 5 months. PMID:25358238

    The effect of pulsed electric field (PEF) treatments of different intensities on the electroporation of the cytoplasmatic membrane of Chlorella vulgaris, and on the extraction of carotenoids and chlorophylls were investigated. Staining the cells with propidium iodide before and after the PEF treatment revealed the existence of reversible and irreversible electroporation. Application of PEF treatments in the range of 20-25 kV cm(-1) caused most of the population of C. vulgaris to be irreversibly electroporated even at short treatment times (5 pulses of 3 µs). However, at lower electric field strengths (10 kV cm(-1)), cells that were reversibly electroporated were observed even after 50 pulses of 3 µs. The electroporation of C. vulgaris cells by PEF higher than 15 kV cm(-1) and duration is higher than 15 µs increased significantly the extraction yield of intracellular components of C. vulgaris. The application of a 20 kV cm(-1) for 75 μs increased the extraction yield just after the PEF treatment of the carotenoids, and chlorophylls a and b 0.5, 0.7, and 0.8 times, respectively. However, further increments in electric field strength and treatment time did not cause significant increments in the extraction yield. The extraction of carotenoids from PEF-treated C. vulgaris cells after 1 h of the application of the treatment significantly increased the extraction yield in comparison to the yield obtained from the cells extracted just after the PEF treatment. After PEF treatment at 20 kV cm(-1) for 75 µs, extraction yield for carotenoids, and chlorophylls a and b increased 1.2, 1.6, and 2.1 times, respectively. A high correlation was observed between irreversible electroporation and percentage of yield increase when the extraction was conducted after 1 h of the application of PEF treatment (R: 0.93), but not when the extraction was conducted just after PEF treatment (R: 0.67).

    Objective: This study evaluated the safety and efficacy of sublative fractional bipolar radiofrequency and bipolar radio frequency combined with diode laser for the treatment of both superficial and deep acne scars in patients with skin types II to V. Design: Prospective, single-center study. Subjects received up to five treatments with sublative fractional bipolar radiofrequency and bipolar radiofrequency combined with diode laser. Treatments were directed to at least two facial (forehead, perioral, cheeks) and/or neck areas with acne scars at four-week intervals. Treatment parameters on each subject were based on skin type and on skin responses to test spots on the target area just before treatment. Setting: Physician office. Participants: Subjects (n=20, aged 40.7±10.5 years [mean ± SD], skin types II–V) with acne scars and without acne lesions enrolled in this prospective study. Measurements: Results were evaluated just before each treatment and at four and 12 weeks after the final treatment using the Goodman Scar Scale, a quantitative method of evaluating scars that attempts to reduce grading subjectivity, as well as by patient satisfaction. Results: Acne scars improved significantly one month after three treatments and improvement persisted for at least 12 weeks after the fifth treatment. Improvement was not affected by skin type. Adverse effects were limited to transient erythema and edema. Conclusion: The combination of diode laser and bipolar radiofrequency energy device in addition to fractionated sublative radiofrequency is a safe and statistically significantly effective combined modality for the treatment of both superficial and deep acne scars in patients with skin types II to V with minimal downtime and no significant side effects.

    Background: Antibiotic resistance is a worldwide problem in acne patients due to regional prescription practices, patient compliance, and genomic variability in Propionibacterium acnes, though the effect of treatment on the resistance has not been comprehensively analyzed. Aims: Our primary objective was to assess the level of antibiotic resistance in the Indian patients and to assess whether there was a difference in the resistance across common treatment groups. Subjects and Methods: A cross-sectional, institutional based study was undertaken and three groups of patients were analyzed, treatment naïve, those on antibiotics and patients on benzoyl peroxide (BPO) and/isotretinoin. The follicular content was sampled and the culture was verified with 16S rRNA polymerase chain reaction, genomic sequencing, and pulsed-field gel electrophoresis. Minimum inhibitory concentration (MIC) assessment was done for erythromycin (ERY), azithromycin (AZI), clindamycin (CL), tetracycline (TET), doxycycline (DOX), minocycline (MINO), and levofloxacin (LEVO). The four groups of patients were compared for any difference in the resistant strains. Results: Of the 52 P. acnes strains isolated (80 patients), high resistance was observed to AZI (100%), ERY (98%), CL (90.4%), DOX (44.2%), and TETs (30.8%). Low resistance was observed to MINO (1.9%) and LEVO (9.6%). Statistical difference was seen in the resistance between CL and TETs; DOX/LEVO and DOX/MINO (P < 0.001). High MIC90 (≥256 μg/ml) was seen with CL, macrolides, and TETs; moreover, low MIC90 was observed to DOX (16 μg/ml), MINO (8 μg/ml), and LEVO (4 μg/ml). Though the treatment group with isotretinoin/BPO had the least number of resistant strains there was no statistical difference in the antibiotic resistance among the various groups of patients. Conclusions: High resistance was seen among the P. acnes strains to macrolides-lincosamides (AZI and CL) while MINO and LEVO resistance was low. PMID:26955094

    Chlorella vulgaris, a marine microalgae strain adaptable to 0-50 g L(-1) of salinity, was selected for studying the coupling system of saline wastewater treatment and lipid accumulation. The effect of total nitrogen (T N) concentration was investigated on algal growth, nutrients removal as well as lipid accumulation. The removal efficiencies of TN and total phosphorus (TP) were found to be 92.2-96.6% and over 99%, respectively, after a batch cultivation of 20 days. To illustrate the response of lipid accumulation to nutrients removal, C. vulgaris was further cultivated in the recycling experiment of tidal saline water within the photobioreactor. The lipid accumulation was triggered upon the almost depletion of nitrate (<5 mg L(-1)), till the final highest lipid content of 40%. The nitrogen conversion in the sequence of nitrate, nitrite, and then to ammonium in the effluents was finally integrated with previous discussions on metabolic pathways of algal cell under nitrogen deficiency.

    Impacts of Chlorella vulgaris with or without co-existing bacteria on the removal of nitrogen, phosphorus and organic matter from wastewaters were studied by comparing the wastewater treatment effects between an algae-bacteria consortium and a stand-alone algae system. In the algae-bacteria system, C.vulgaris played a dominant role in the removal of nitrogen and phosphorus, while bacteria removed most of the organic matter from the wastewater. When treating unsterilized wastewater, bacteria were found to inhibit the growth of algae at >231 mg/L dissolved organic carbon (DOC). Using the algae-bacteria consortium resulted in the removal of 97% NH4(+), 98% phosphorus and 26% DOC at a total nitrogen (TN) level of 29-174 mg/L. The reaction rate constant (k) values in sterilized and unsterilized wastewaters were 2.17 and 1.92 mg NH4(+)-N/(mg algal cell ·d), respectively. PMID:23973976

    Modalities for the treatment of atrophic facial acne scars have been studied extensively. One, an erbium:yttrium-aluminum garnet (Er:YAG) laser device that generates both short, ablative pulses of high fluence and long, coagulative pulses of low fluence, has been shown to achieve tissue contraction, control intraoperative bleeding and deliver energy quickly and uniformly. The investigators were able to achieve significant depth and ablation with repetitive pulses at the same site and remove the epidermis with a single pass. Subsequent studies showed that facial acne scars of patients with dark skin types could be treated with a similar device. This report reviews the development of the Er:YAG laser and the preliminary results of a study in which moderate-to-severe facial acne scars of 180 Asian patients (skin types III-IV) were treated successfully with a dual-mode Er:YAG laser device.

    Acne is a common skin disease characterized by elevated sebum production and inflammation of the sebaceous glands. We have previously shown that a non-psychotropic phytocannabinoid ((-)-cannabidiol [CBD]) exerted complex anti-acne effects by normalizing 'pro-acne agents'-induced excessive sebaceous lipid production, reducing proliferation and alleviating inflammation in human SZ95 sebocytes. Therefore, in this study we aimed to explore the putative anti-acne effects of further non-psychotropic phytocannabinoids ((-)-cannabichromene [CBC], (-)-cannabidivarin [CBDV], (-)-cannabigerol [CBG], (-)-cannabigerovarin [CBGV] and (-)-Δ(9) -tetrahydrocannabivarin [THCV]). Viability and proliferation of human SZ95 sebocytes were investigated by MTT and CyQUANT assays; cell death and lipid synthesis were monitored by DilC1 (5)-SYTOX Green labelling and Nile Red staining, respectively. Inflammatory responses were investigated by monitoring expressions of selected cytokines upon lipopolysaccharide treatment (RT-qPCR, ELISA). Up to 10 μm, the phytocannabinoids only negligibly altered the viability of the sebocytes, whereas high doses (≥50 μm) induced apoptosis. Interestingly, basal sebaceous lipid synthesis was differentially modulated by the substances: CBC and THCV suppressed it, and CBDV had only minor effects, whereas CBG and CBGV increased it. Importantly, CBC, CBDV and THCV significantly reduced arachidonic acid (AA)-induced 'acne-like' lipogenesis. Moreover, THCV suppressed proliferation, and all phytocannabinoids exerted remarkable anti-inflammatory actions. Our data suggest that CBG and CBGV may have potential in the treatment of dry-skin syndrome, whereas CBC, CBDV and especially THCV show promise to become highly efficient, novel anti-acne agents. Moreover, based on their remarkable anti-inflammatory actions, phytocannabinoids could be efficient, yet safe novel tools in the management of cutaneous inflammations. PMID:27094344

    Bipolar fractional radiofrequency (FRF) device was firstly FDA-approved for treating atrophic acne scar in 2008 through the process of dermal coagulation and minimal epidermal ablation. The average energy at 60 mJ/pin was widely used to treat atrophic acne scars. However, the higher energy was delivered, the deeper ablation and coagulation were found. At present, the new generation of a device with bipolar FRF technology with electrode-pin tip was developed to maximize ability to deliver energy up to 100 mJ/pin. The objective of the study was to explore and compare the efficacy of utilizing high energy (100 mJ/pin) and moderate energy (60 mJ/pin) of bipolar fractional radiofrequency in treatment of atrophic acne scar in Asians. This is a split-face, double-blinded, randomized control trial, pilot study by using parallel group design technique. Thirty healthy subjects with Fitzpatrick skin phototype III-IV diagnosed as atrophic acne scares were enrolled. All subjects received four monthly sessions of bipolar FRF treatment. Left and right facial sides of individual patients were randomly assigned for different energy (high energy at 100 mJ/pin versus moderate energy at 60 mJ/pin). Acne scars improvement was blinded graded by dermatologist using global acne scarring score (GASS) which was subjectively evaluated at baseline, 1-, 3-, and 6-month follow-up. Objective scar analysis was also done using UVA-light video camera to measure scar volume, skin smoothness, and wrinkle at baseline, 3-, and 6-month follow-up after the last treatment. Side effects including pain, erythema, swelling, and crusting were also recorded. Thirty subjects completed the study with full 4-treatment course. The mean GASS of high energy side and moderate energy side was significantly reduced at 1-, 3-, and 6-month follow-up visits. At 1 month follow-visit, high energy side demonstrated significant improvement compared with moderate energy side (p = 0.03). Postinflammatory hyperpigmentation

    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.

    Acne is a common disease in Westernized nations, particularly among adolescents and young adults. Acne has substantial effects on quality of life, making treatment essential. Medical nutrition therapy as a potential treatment for acne is not new, although the literature examining diet and acne during the past 100 years is mixed. During the late 1800s and early 1900s, diet was commonly used as an adjunct treatment for acne. During the 1960s, however, the diet-acne connection fell out of favor. In recent years, dermatologists and registered dietitians have revisited the idea and become increasingly interested in the role of medical nutrition therapy in acne treatment. This article reviews the history and existing literature examining the association between diet and acne. Although the total number of studies conducted within the past 40 years is relatively small, the growing body of epidemiologic and experimental evidence suggests a relationship between diet and acne. Compared with other dietary factors, more research examines dietary glycemic load. The evidence is more convincing for high glycemic load diets, compared with other dietary factors. To date there are no randomized controlled trials investigating the relationship between frequent dairy or milk consumption and acne. Similarly, the number of research studies examining the relationship between dietary fat and/or n-3 fatty acids is sparse and the evidence is less robust. Taken together, several methodologic limitations need to be addressed, and additional research, preferably randomized controlled trials, is warranted before comprehensive evidence-based guidelines can be established. While dermatologists and registered dietitians continue to debate and research the potential relationship between diet and acne, the best dietary approach is to address each acne patient individually, carefully considering the possibility of dietary counseling.

    Topical therapy of acne vulgaris (acne) is very common, however cutaneous tolerability can influence patient adherence, and concerns about skin irritation have lead to a number of comparative split-face studies. Advances in formulation technology have provided new fixed combinations with lower concentrations of potentially irritating ingredients without compromising efficacy. These developments now afford the opportunity to formulate fixed combinations with higher concentrations of active ingredients that may provide the greater efficacy needed in more severe disease with good tolerability.
    Here, we compare the tolerability of two such developments, clindamycin-BP 3.75% gel and adapalene 0.3%-BP 2.5% gel, in healthy volunteers with no apparent facial redness or dryness over 21-days, using a split-face methodology.
    Clindamycin-BP 3.75% gel was more tolerable than adapalene 0.3%-BP 2.5% gel over the duration of the two studies, with statistically significant differences in cumulative change from baseline starting as early as day 4 (stinging), day 5 (erythema, dryness, and scaling), day 6 (burning), and day 8 (itching); and in composite irritation index (stinging, erythema, dryness, scaling, burning, and itching) from day 4. Transepidermal water loss was less with clindamycin-BP 3.75% gel (statistically significant from day 8). Adverse events were twice as common with adapalene 0.3%-BP 2.5% gel.
    These data suggest that clindamycin-BP 3.75% gel is likely to be better tolerated than adapalene 0.3%-BP 2.5% gel in moderate-to-severe acne.

    1985-01-01

    Treatment of acne prior to referral was recorded retrospectively in 72 patients alleged to have responded inadequately; 60% had used benzoyl peroxide (BP) but most applied it to lesions only. Although 86% had used tetracycline, most did not take it correctly for maximum absorption and took less than 1 g/day. Most patients used both drugs for less than three months. Eight-two patients referred because of inadequate response were treated with: (I) 5% benzoyl peroxide (BP) (23 patients); (II) 5% BP and 0.5 g/day oxytetracycline (OTC) (24 patients); (III) 5% BP and 1 g/day OTC (18 patients); (IV) 5% BP and 1.5 g/day OTC (17 patients). BP was applied incrementally from 30 min up to 8-10 hours daily to the entire area affected and OTC taken as a single morning dose. Median grade of severity (0-10 analogue scale) fell by 2 in Groups I and II (P less than 0.05), by 2.5 in Group III (P less than 0.05) and by 3 in Group IV (P less than 0.05); number of lesions fell by 56% +/- 7% (s.e.), (P less than 0.001) 70% +/- less than 10% (P less than 0.001), 75% +/- 8% (P less than 0.001) and 78% +/- 10% (P less than 0.001) respectively and treatment was well tolerated. Thus, although effective drugs are frequently prescribed in acne, method of use, dose and duration are likely to determine response. PMID:2941583

    Pemphigus vulgaris is a rare, potentially fatal, autoimmune blistering disease of the skin and mucous membranes. Treatment of this disease is problematic because of a lack of high-grade, evidence-based recommendations, the side-effect profiles of the therapies available, and the extensive supportive care that afflicted patients require. The authors present the unfortunate course of a patient with severe pemphigus vulgaris who was admitted to the U.S. Army Institute of Surgical Research Burn Center, to demonstrate the potential complications of therapy. Given the patient's complex course, the authors reviewed the literature and share in this article the most up-to-date treatment recommendations for patients with pemphigus vulgaris. The authors' review of the literature supports using conventional therapy consisting of high-dose corticosteroids and an adjuvant immunosuppressant for mild to moderate cases of pemphigus vulgaris. The immunosuppresants recommended are mycophenolate mofetil, azathioprine, and cyclophosphamide, in order of preference, based on their side-effect profiles and steroid-sparing effects. For severe or recalcitrant cases of pemphigus vulgaris, the authors recommend adding rituximab as early as possible. If increased risk of infection is of particular concern, the use of intravenous immunoglobulin in place of rituximab is advised. PMID:24572296

    The production of chondroitin sulfatase, hyaluronidase, deoxyribonuclease, gelatinase, phosphatase, lecithinase, and hemolysins was examined in 95 strains of Propionibacterium acnes and four related species of anaerobic, respectively, microaerophilic coryneform bacteria (P. avidum, P. lymphophilum, P. granulosum, and Corynebacterium minutissimum). All enzymes could be demonstrated in at least one representative of the species tested. Those Propionibacterium species most frequently found in acne vulgaris lesions, i.e., P. acnes and P. granulosum, proved to be the most active organisms concerning the production of the enzymes tested. P. avidum, on the other hand, showed the highest rate of hemolytic activity. PMID:201661

    Physical modalities provide an important adjunct to medical treatment of acne and rosacea. In patients who cannot tolerate or fail medical treatments, physical modalities offer an alternative approach. For cases of acne scarring, phymatous changes of rosacea, and rosacea-associated telangiectasia, physical modalities such as laser and light treatments represent the treatment of choice. We will review the use of laser and light treatments, photodynamic therapy, and other physical modalities such as targeted therapies for the treatment of acne and rosacea. PMID:27416315

    While daylight photodynamic therapy (PDT) is a simpler and more tolerable treatment procedure for both clinicians and patients, it has never been applied for acne treatment. In this study, we evaluated efficacy, safety and histological changes of facial acne after application of the novel variant of 5-aminolevulinate (ALA)-ester, 1.5% 3-butenyl ALA-bu gel, using daylight only as the potential visible light source. Forty-six acne patients were randomly assigned to either ALA-bu or vehicle application group in a double-blind fashion. Both groups applied the allocated gel to facial acne lesions every other day for 12 weeks. At the final 12 week, both inflammatory and non-inflammatory acne lesions had decreased significantly by 58.0% and 34.1% in the ALA-bu group, respectively. Only a few patients expressed mild adverse effects. In the histopathological analysis, attenuated inflammatory cell infiltrations were observed and immunostaining intensities for interleukin-8, interleukin-1β, matrix metalloproteinase-9 and phosphorylated nuclear factor-κB were reduced concomitantly. Changes of their mRNA expression demonstrated comparable patterns. In conclusion, this ambulatory PDT was effective, very well tolerated and convenient for treating inflammatory acne lesions. Experimental results correlated well with clinical results. This novel regimen would provide a viable option for acne therapy. PMID:26660491

    Topical therapies are effective in managing acne vulgaris but are associated with local adverse effects such as irritation and dryness. This 4-week pilot study compared skin hydration in 36 healthy adult women randomized to treatment with 1 of 4 topical therapies: 2 different (jar and tube) clindamycin 1%/benzoyl peroxide 5% gels, sodium sulfacetamide 10% lotion, or over-the-counter (OTC) moisturizing cream. Subjects treated with OTC moisturizer or sodium sulfacetamide exhibited decreased water loss, increased water retention, similar or improved levels of skin hydration, and decreased desorption rates. In contrast, subjects treated with jar or tube clindamycin/benzoyl peroxide had increased water loss, decreased water retention, decreased hydration, and increased desorption rates. Skin dryness decreased slightly in the moisturizer group. No serious adverse events occurred. Overall, the OTC moisturizer had the best skin hydration profile. Sodium sulfacetamide demonstrated some moisturizing characteristics, and no clinically relevant differences were noted between jar and tube clindamycin/benzoyl peroxide gels. PMID:17763612

    Pemphigus is an autoimmune disease that results from the interaction between predisposing genetic factors and exogenous agents, mainly drugs and viruses. Herein we report the case of a 66-year-old woman referred to our department for the onset of painful oral erosions and bullous lesions on the torso. Clinical, laboratory and histopathological investigations led to the diagnosis of pemphigus vulgaris. Two weeks before the outbreak of the lesions, the patient had suffered from a viral pharyngitis, subsequently diagnosed as herpangina, and had been taking an oral cephalosporin (cefixime) for 1 week to prevent possible bacterial complications. A relationship between the onset of pemphigus and coxsackievirus infection or cefixime administration or both was supposed. The case may represent a peculiar paraviral eruption, where a predisposing pemphigus-prone genetic background paved the way for the acantholytic autoimmune disorder as a consequence of the combined effect of the coxsackievirus infection and the cephalosporin treatment.

    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

    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

    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.

    Cosmetic tattoos are becoming increasingly popular. Elimination of cosmetic tattoos is sought because of misplacement or migration of tattoo pigment, allergic reactions to the various pigments or dissatisfaction of the customer for various reasons. Removal of unwanted pigment is a domain of laser surgery using various Q-switched laser systems, such as the ruby, alexandrite, pulsed dye and Nd:YAG lasers. Dark colours are easily removed by these lasers, whereas red, pink and skin-toned pigment may turn black if exposed to Q-switched laser light. This ink-blackening occurs because Q-switched lasers heat up the pigments, which consist of ferric oxide, and reduce them into ferrous oxide, which is black. Laser-induced black ink is not always readily removed. A successful ruby laser-removal of laser-induced blackened cosmetic tattoos for acne scar camouflage is reported. The advantageous outcome in this case contrasts with other published cases where laser-darkened pigment had to be removed by other measures, or was permanent. Test site treatment can limit the problem to some degree but, in addition to test-treating, some kind of 'tattoo identification card' could help to prevent problems in this field and allow 'in vitro' test treatment.

    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.

    Background Although described by Hippocrates in 400 B.C., pemphigus disease still needs a safe therapeutical approach, given that the currently used therapies (i.e. corticosteroids and immunosuppressive drugs) often provoke collateral effects. Here we present preliminary data on the possible use of a proteomics derived desmoglein peptide which appears promising in halting disease progression without adverse effects. Methods The low-similarity Dsg349–60REWVKFAKPCRE peptide was topically applied for 1 wk onto a lesion in a patient with a late-stage Pemphigus vulgaris (PV) complicated by diabetes and cataract disease. The peptide was applied as an adjuvant in combination with the standard corticosteroid-based immunosuppressive treatment. Results After 1 wk, the treated PV eroded lesion appeared dimensionally reduced and with an increased rate of re-epithelization when compared to adjacent non-treated lesions. Short-term benefits were: decrease of anti-Dsg antibody titer and reduction of the corticosteroid dosage. Long-term benefits: after two years following the unique 1-wk topical treatment, the decrease of anti-Dsg antibody titer persists. The patient is still at the low cortisone dosage. Adverse effects: no adverse effect could be monitored. Conclusion With the limits inherent to any preliminary study, this case report indicates that topical treatment with Dsg349–60REWVKFAKPCRE peptide may represent a feasible first step in the search for a simple, effective and safe treatment of PV.

    Psoriasis vulgaris is a common and chronic inflammatory skin disease which has the potential to significantly reduce the quality of life in severely affected patients. The incidence of psoriasis in Western industrialized countries ranges from 1.5 to 2%. Despite the large variety of treatment options available, patient surveys have revealed insufficient satisfaction with the efficacy of available treatments and a high rate of medication non-compliance. To optimize the treatment of psoriasis in Germany, the Deutsche Dermatologische Gesellschaft and the Berufsverband Deutscher Dermatologen (BVDD) have initiated a project to develop evidence-based guidelines for the management of psoriasis. The guidelines focus on induction therapy in cases of mild, moderate, and severe plaque-type psoriasis in adults. The short version of the guidelines reported here consist of a series of therapeutic recommendations that are based on a systematic literature search and subsequent discussion with experts in the field; they have been approved by a team of dermatology experts. In addition to the therapeutic recommendations provided in this short version, the full version of the guidelines includes information on contraindications, adverse events, drug interactions, practicality, and costs as well as detailed information on how best to apply the treatments described (for full version, please see Nast et al., JDDG, Suppl 2:S1–S126, 2006; or http://www.psoriasis-leitlinie.de).

    Psoriasis vulgaris is a common chronic, inflammatory, multisystem disorder that affects approximately 1.5% to 3.4% of the population in the Middle East. The disease has an impact on the quality of life in a significant number of affected patients. The majority of patients (approximately 70%) have mild to moderate psoriasis that is manageable with topical agents, which generally show a high efficacy to safety ratio. Topical agents can be used alone when treating patients with limited disease or may be used as adjunctive therapy for patients with more extensive psoriasis undergoing systemic treatment. Treatment should also be customized to meet individual patients' needs. To optimize the topical treatment of psoriasis in the Levant and Iraq area, dermatology experts from Iraq, Jordan, Lebanon, Palestine, and Syria met and initiated a project to develop guidelines and recommendations for the topical management of psoriasis. The guidelines are based on literature evidence and experts' opinions. We present recommendations for the use of topical corticosteroids, vitamin D analogues, calcineurin inhibitors, tazarotene, salicylic acid, anthralin, and coal tar, as well as combination therapy, based on their efficacy and safety profiles.

    Historically, the relationship between diet and acne has been highly controversial. Before the 1960s, certain foods were thought to exacerbate acne. However, subsequent studies dispelled these alleged associations as myth for almost half a century. Several studies during the last decade have prompted dermatologists to revisit the potential link between diet and acne. This article critically reviews the literature and discusses how dermatologists might address diet when counseling patients with acne. Dermatologists can no longer dismiss the association between diet and acne. Compelling evidence exists 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, antioxidants, zinc, vitamin A, and dietary fiber remain to be elucidated. This study was limited by the lack of randomized controlled trials in the literature. We hope that this review will encourage others to explore the effects of diet on acne. PMID:20338665

    Background Acne keloidalis nuchae (AKN) is a chronic scarring folliculitis with fibrotic papules on the occipital scalp. Its treatment is limited and unsatisfactory. Objectives To determine if targeted ultraviolet B (tUVB) phototherapy will (1) improve the clinical appearance of AKN and (2) induce extracellular matrix remodeling in affected lesions. Methods Eleven patients with AKN were enrolled in a prospective, randomized, split-scalp comparison study. One randomly selected side of the scalp was treated with tUVB up to three times weekly for eight weeks. After week 8, both sides were treated for eight additional weeks. Assessment included lesion counts in two 3×3 cm regions of interest (ROI), one on each side of the scalp (ROI-1: tUVB week 0–16, ROI-2: tUVB week 9–16), patient self-assessment, and analysis of MMP-1, MMP-9, TGF-β1, and Col1a1 mRNA expression by qRT-PCR. Results Before treatment, the mean lesion count was similar between tUVB-treated and untreated sides (14.8 vs. 15.0). After eight weeks of tUVB, the mean lesion count decreased significantly to 9.4±1.2 (P=0.03), with no change on the untreated side. With continued treatment, the mean lesion count in ROI-1 decreased further to 7±1.5 (P=0.04) after 16 weeks of tUVB. Conclusion Targeted UVB significantly improved clinical appearance of AKN, led to patient satisfaction, and was well tolerated. PMID:24863570

    Background: Therapeutic success in acne patients not only depends on the appropriate selection of drugs but also on the patient’s treatment adherence or compliance. Lack of adherence is an important problem both in general medicine and in dermatologic practice. Objective: To evaluate the impact of oral and written counseling on treatment adherence among acne patients. Patients and Methods: Eighty patients were randomized into two groups of 40 patients each. The intervention group received a patient information leaflet (apart from oral counseling), and instructions were reinforced by a telephone call within 15 days of treatment onset. The second group (control group) received treatment indications as usual (oral counseling in-office only). Both groups were followed up with a phone call, evaluating adherence to treatment according to self-reporting of patients at 30, 60, 90 days, and 6 months. Results: Better adherence to treatment was observed in the intervention group. This difference was significant only within the first month of treatment (80% versus 62%, p = 0.043). The beneficial effect of written counseling plus a phone call decreased in subsequent months. Conclusion: Written counseling significantly improves adherence within the first month of treatment. These results suggest that it is reasonable to spend time and resources in written counseling in order to optimize adherence to treatment. PMID:26693083

    Acne is a very widespread cosmesis problem. Isotretinoin, a synthetic oral retinoid is used to treat acne, which is androgen dependent. Numerous side-effects occur from this treatment. 5-alpha-Reductase plays a critical role in normal and pathological androgen-dependent processes. We have taken the approach to develop a selective, effective, topically-applied 5-alpha-reductase inhibitor to modify unwanted or pathological processes in the pilosebaceous unit such as acne. Toward this goal, we have previously developed a selective liposome hair follicle targeting system. We demonstrate in this report that the 5-alpha-reductase inhibitor N,N-diethyl-4-methyl-3-oxo-4-aza-5alpha-androstane-17beta-carboxamide (4-MA) incorporated into liposomes induces apoptosis and inhibits growth of the dihydrotestosterone (DHT)-dependent hamster flank organ sebaceous gland. We have compared topical application of liposome 4-MA and solvent-formulated 4-MA and observed selective efficacy of topical application of liposome 4-MA by the reduction of size and induction of apoptosis only in the treated hamster flank organ. Apoptosis induced by liposome 4-MA in the treated flank organ sebaceous gland cells was observed both by assays for DNA fragments (transferase deoxytidyl uridine end labeling) and by observation of condensed and fragmented nuclei. When 4-MA was topically applied formulated in ethanol and glycerol without liposomes, the selective efficacy was lost. Liposome 4-MA did not significantly affect prostate weight, testosterone/DHT ratios or bodyweight gain compared to controls indicating safety as well as efficacy of topical application of liposome 4-MA for pathological processes such as acne.

    1985-01-01

    Acne is the result of excessive grease on the skin. The successful treatment of acne depends essentially on the degreasing of the skin to an extent which produces peeling, which is the observable index of adequate treatment. The use of antibiotics is supplementary to degreasing and peeling. Degreasing is best achieved by thrice daily washing with Neutrogena acne cleansing soap, followed by the application of a benzoyl peroxide preparation of a suitable strength. If necessary, further degreasing can be achieved by cleansing with isopropyl alcohol after washing with the Neutrogena soap. PMID:2941579

    Biofuels from algae are considered a technically viable energy source that overcomes several of the problems present in previous generations of biofuels. In this research high pressure steaming (HPS) was studied as a hydrothermal pre-treatment for extraction of lipids from Chlorella vulgaris, and analysis by response surface methodology allowed finding operational points in terms of target temperature and algae concentration for high lipid and glucose yields. Within the range covered by these experiments the best conditions for high bio-crude yield are temperatures higher than 174°C and low biomass concentrations (<5 g/L). For high glucose yield there are two suitable operational ranges, either low temperatures (<105°C) and low biomass concentrations (<4 g/L); or low temperatures (<105°C) and high biomass concentrations (<110 g/L). High pressure steaming is a good hydrothermal treatment for lipid recovery and does not significantly change the fatty acids profile for the range of temperatures studied. PMID:24852645

    Objective: This study aims to compare the differences of clinical efficacy and safety of treatment of stable psoriasis vulgaris with calcipotriene ointment in combination with 308 nm excimer laser to 308 nm excimer laser alone. Methods: Randomized, open and self-control trial was conducted in 36 selected patients. The skin lesions from these patients with stable psoriasis vulgaris were divided into two sides along the midline of torso, one side was treated with 308 nm excimer laser, 2 times/week, at meantime Calcipotriene was applied externally, 2 times/day (treatment group); the other side was given 308 nm excimer laser alone, 2 times/week, the treatment period was 6 weeks (control group). Skin lesion area, PASI scores and cumulative doses of 308 nm excimer laser in patients with psoriasis were assessed before treatment and on weeks 2, 4 and 6 after treatment. Results: 32 of 36 patients with stable psoriasis vulgaris completed study, effective rates in two groups were better on week 6 (84.37%, 56.25%) than on week 4 (53.12%, 37.5%) and on week 2 (31.25%, 18.75%) (P < 0.05). Effective rate on week 6 in control group (56.25%) was lower than treatment group (84.37%) (P < 0.05). The two groups showed that PASI scores on weeks 2 and 4 after treatment were significantly lower than before treatments (P < 0.05), and PASI scores on week 6 in treatment group was significantly lower than control group (P < 0.05). The average cumulative laser doses in treatment group at the end of trial was 4.69 (2.03) J/cm2, which was significantly lower than in control group 8.41 (2.42) J/cm (P < 0.05). Treatment efficacies in the head, folds, back, abdomen and limbs were similar and no serious adverse effects, however the number of treatment and irradiation doses in the head and folds were significantly less than in back, abdomen and limbs (P < 0.05). Conclusions: Treatment of psoriasis vulgaris with 308 nm excimer laser in combination with external application of Calcipotriene ointment

    Background Psoriasis is an autoimmune, inflammatory, and chronic disease. Recent studies have evaluated serum endocan and nesfatin-1 levels in patients with inflammatory disorders. The neutrophil-to-lymphocyte ratio (NLR) is an inflammatory marker currently used in many diseases. The aim of the present study was to evaluate NLR, serum endocan, and nesfatin-1 levels in psoriasis vulgaris before and after narrow-band ultraviolet B (NB-UVB) phototherapy treatment and compared to healthy controls. Material/Methods This study was conducted on a total of 88 cases, 39 of which had psoriasis vulgaris and 49 were healthy volunteers. Thirty-nine psoriasis vulgaris patients underwent NB-UVB phototherapy treatment for 3 months. NLR, serum endocan, and nesfatin-1 levels were measured in all psoriasis patients before and after NB-UVB phototherapy and in the control group. Results Compared with the control group, neutrophil count and NLR were significantly higher (p<0.001) in psoriasis patients before NB-UVB phototherapy. Serum endocan levels were significantly correlated with disease activity before treatment. There was no significant difference in NLR, serum endocan, and nesfatin-1 levels in psoriasis patients before and after NB-UVB phototherapy (p>0.05). Conclusions The current study shows that NLR was higher in psoriasis vulgaris patients when compared with the control group, whereas serum endocan and nesfatin-1 levels were not significantly different. In addition, NB-UVB phototherapy did not affect NLR, serum endocan, or nesfatin-1 levels. Further larger-scale studies are required on this subject. PMID:27070789

    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.

    Introduction Acne and hirsutism are common manifestations of hyperandrogenism. Aim To investigate whether or not acne is present in women with hirsutism, associated with different clinical, endocrine and ultrasonographic features. Material and methods The prospective study included 135 women with hirsutism, aged 14–46 years. We measured the levels of hormones with radioimmunoassay/immunoradiometric assay methods. Results Acne were present in 63 (47.6%) women with hirsutism. Sixty women had mild forms of acne, including: whiteheads, blackheads, papules and pustules. Only 3 women had moderate to severe acne, including nodules. In a group of women with hirsutism and acne, 6 (9.5%) were obese. In our study we found a high prevalence of androgen excess among hirsute women with acne: total testosterone was increased in 79%, free testosterone in 20.6%, androstenedione in 69.8%, dehydroepiandrosterone sulfate (DHEAS) in 30.1%, 17-OH-progesterone 68.2% and sex hormone-binding globulin (SHBG) was decreased in 33.3% of women. Women with hirsutism and acne have received oral contraceptives for a year, without or in a combination with other medication. Thirty-four (53.9%) women have shown improvement in hirsutism and acne. Conclusions In this study we found a high prevalence of acne in hirsute women. The prevalence of acne was higher in polycystic ovarian syndrome. Since these women have associated endocrine changes it is important to correct them with hormonal therapy. PMID:25610349

  16. Proteomic identification of secreted proteins of Propionibacterium acnes

    PubMed Central

    2010-01-01

    Background The anaerobic Gram-positive bacterium Propionibacterium acnes is a human skin commensal that resides preferentially within sebaceous follicles; however, it also exhibits many traits of an opportunistic pathogen, playing roles in a variety of inflammatory diseases such as acne vulgaris. To date, the underlying disease-causing mechanisms remain ill-defined and knowledge of P. acnes virulence factors remains scarce. Here, we identified proteins secreted during anaerobic cultivation of a range of skin and clinical P. acnes isolates, spanning the four known phylogenetic groups. Results Culture supernatant proteins of P. acnes were separated by two-dimensional electrophoresis (2-DE) and all Coomassie-stained spots were subsequently identified by MALDI mass spectrometry (MALDI-MS). A set of 20 proteins was secreted in the mid-exponential growth phase by the majority of strains tested. Functional annotation revealed that many of these common proteins possess degrading activities, including glycoside hydrolases with similarities to endoglycoceramidase, β-N-acetylglucosaminidase and muramidase; esterases such as lysophospholipase and triacylglycerol lipase; and several proteases. Other secreted factors included Christie-Atkins-Munch-Petersen (CAMP) factors, glyceraldehyde 3-phosphate dehydrogenase (GAPDH), and several hypothetical proteins, a few of which are unique to P. acnes. Strain-specific differences were apparent, mostly in the secretion of putative adhesins, whose genes exhibit variable phase variation-like sequence signatures. Conclusions Our proteomic investigations have revealed that the P. acnes secretome harbors several proteins likely to play a role in host-tissue degradation and inflammation. Despite a large overlap between the secretomes of all four P. acnes phylotypes, distinct differences between predicted host-tissue interacting proteins were identified, providing potential insight into the differential virulence properties of P. acnes isolates

    Ascending urinary tract infections with stone formation have been produced experimentally in rats, using a modification of the method of Vermuelen & Goetz (1954a, b). A zinc disc infected with a culture of Proteus vulgaris was inserted into the bladder by suprapubic cystotomy under ether anaesthesia. The pH of the urine rises from 6.9 to 8 or 9 and calculi develop in the bladder within a few days of infection. The bladder and ureters become swollen, distended and inflamed, and renal abscesses develop. Death from renal failure generally occurs within 10 days of infection. Oral treatment with nitrofurantoin was commenced three days after infection and continued for one month. This arrested the initial rise in urine alkalinity and stone formation, and few, if any, macroscopic lesions were found at post-mortem examination. Of nine nitrofuran derivatives examined for activity against this infection several showed slight activity, but only one, N-(5-Nitrofurfurylidene)-γ-butyric acid, was as active as nitrofurantoin when given at four times the dose, but it was also one-third as toxic. It is concluded that this technique is suitable for the examination of potential urinary antiseptics. ImagesFig. 1 PMID:13964160

    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. PMID:21342143

    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.

    Background: Postinflammatory hyperpigmentation (PIH) is a common sequela seen in the Indian population following affliction by acne. It is psychologically extremely disturbing for the patients and can severely affect the quality of life. Very few therapeutic modalities have proved to be really efficacious in this condition. Aims: The aim was to review our experience with 1,064-nm Q-switched neodymium-doped yttrium aluminum garnet (QSNY) laser in the treatment of PIH. Materials and Methods: Seventy-eight patients with postacne hyperpigmentation were included in the study. They were treated with six sessions at two weekly intervals using a 1,064-nm QSNY laser. Patient and physician scores were assessed at 1 month and 3 months after the last treatment. Clinical photographs also were reviewed to determine the efficacy. Adverse effects were noted. Results: Seventy percent of the patients reported significant improvement in hyperpigmentation as compared to the baseline. The majority of the adverse events were limited to mild, brief erythema. Conclusion: The 1,064-nm QSNY laser is an effective modality for the treatment of PIH caused by acne. PMID:26865787

    2006-01-01

    Oral contraceptives (OCs) have been shown to effectively treat acne. Clinical trials of various doses of ethinyl estradiol (EE) combined with progestins such as levonorgestrel, desogestrel, norgestimate, gestodene, cyproterone acetate and drospirenone in monophasic, triphasic and combiphasic formulations used to treat acne in women are reviewed here. Open-label and comparative studies beginning in the 1980s were the first to demonstrate objective and subjective reductions in the incidence of acne, severity of existing acne and seborrhea. Placebo-controlled trials have corroborated these findings with a trend toward effective acne treatment with declining doses of EE. Significant reductions in total, inflammatory and noninflammatory lesions compared with placebo have been demonstrated with an OC containing the low dose of 20 microg of EE. Collectively, these findings support the use of low-dose OCs for the treatment of acne. PMID:16371290

    Acne is a multifactorial chronic dermatosis that can be effectively treated with adjuvant medications. The objective of our study was to compare the tolerability and efficacy of 2 adjuvant therapies combining clindamycin phosphate 1.2%-benzoyl peroxide 5% (CLNP-BPO5) or clindamycin phosphate 1.2%-benzoyl peroxide 2.5% (CLNP-BPO2.5) fixed-dose gels with tazarotene (TZ) cream 0.1% (CLNP-BPO5/TZ vs CLNP-BPO2.5/TZ) when applied topically once daily for 12 weeks in participants with moderate to severe facial acne. Forty participants were randomized to receive CLNP-BPO5/TZ or CLNP-BPO2.5/TZ in a parallel-group study and were evaluated at baseline as well as weeks 1, 2, 4, 8, and 12 (or at early termination). In both groups, tolerability assessments increased by week 1 but gradually returned toward baseline levels by week 12. At week 4, the mean change in burning/stinging was significantly higher in the CLNP-BPO5/TZ group compared with the CLNP-BPO2.5/TZ group (P<.05). No other significant differences were observed for the tolerability, efficacy, quality of life (QOL), or participant preference assessments. Our study shows that CLNP-BPO5 or CLNP-BPO2.5 fixed-dose gels in combination with TZ cream 0.1% are generally well-tolerated and effective treatments of moderate to severe facial acne when applied once daily for up to 12 weeks.

    2015-06-01

    Acne has long been understood to have a complex physiological basis involving several main factors: hormonally-stimulated sebum production, abnormal keratinization of the pilosebaceous duct, and an inflammatory immune response to Propionibacterium acnes. Recent studies at the molecular and cellular level have begun clarifying how all of these factors interact, and the role of the innate immune system is better appreciated. Inflammation has been demonstrated in all acne lesions - the preclinical microcomedo, comedones, inflammatory lesions, 'post-inflammatory' erythema or hyperpigmentation, and scarring. Inflammation localized to the pilosebaceous unit can be considered the defining feature of acne and should be addressed via multiple therapeutic pathways. Clinicians tend to think oral antibiotics should be used to 'calm' inflammatory acne, but there is good evidence showing that topical retinoids also have anti-inflammatory properties as a class effect. For best therapeutic outcomes, most patients with acne should be treated first line with a topical retinoid plus an antimicrobial agent, as has been demonstrated in thousands of patients involved in clinical trials and recommended by the Global Alliance to Improve Outcomes in Acne for more than a decade. Moving away from reliance on antibiotic therapy for acne is particularly important in an era of worsening antimicrobial resistance and worldwide calls to reduce antibiotic use. Improved understanding about the role of P. acnes and the innate immune system in acne should help clinicians in designing efficacious treatment strategies. PMID:26059728

    Introduction There is a growing tendency towards herbal medicines for treatment of vaginitis. Antibacterial and antifungal effects of Myrtus communis L and Berberis vulgaris have been demonstrated invitro and invivo. Aim This study aimed to compare the therapeutic effects of the vaginal gel of Berberis vulgaris 5% (in metronidazole base) and Myrtus communis L 2% (in metronidazole base) with only metronidazole vaginal gel 0.75% on bacterial vaginosis. Materials and Methods This study was a randomized clinical trial research on 120 married women aged 18-40 years affected by bacterial vaginosis attended for treatment to gynaecology clinic of Hajar Hospital (Shahrekord, Iran). They were randomly divided into three groups of 40 participants. Diagnostic criteria were Amsel’s criteria. Myrtus communis L, Berberis vulgaris vaginal gel or metronidazole vaginal gel for five-night usage were prescribed to each group, and after 7 days therapeutic effects were assessed. Data analysis was performed using ANOVA and Chi-square tests. Results A statistically significant difference was observed with regard to treatment response among the study groups (p<0.001), with Myrtus communis L and Berberis vulgaris groups having a better response than metronidazole gel alone. Moreover, there was no significant difference between Myrtus communis L and Berberis vulgaris groups (p= 0.18). The patients in groups of Myrtus communis L or Berberis vulgaris in metronidazole base did not experience any relapse, but in metronidazole group, 30% of patients experienced relapse during three weeks follow up. Conclusion Findings of the study showed that treatment with a combination of Myrtus communis L or Berberis vulgaris in metronidazole base improve the efficacy of bacterial vaginosis therapy.

    Pemphigus vulgaris is an autoimmune disease characterized by suprabasal blisters with acantholysis, which has a fatal course in a large number of untreated patients. Systemic corticosteroid therapy is considered first-line therapy. Adjuvant treatment with the goal of sparing corticosteroids include, among others, dapsone. This drug is not without side effects and its use requires clinical and laboratory control. We present a patient with PV initially managed with suboptimal dose of prednisone, evolving into drug-induced hepatitis after introduction of dapsone. PMID:26312673

    In a comparative study, 20 ambulatory patients suffering from chronic psoriasis vulgaris with plaques were treated with preparations containing either dithranol (0.1/0.2%) plus urea (17%) or desoximetasone (0.25%). In the two groups, 7 and 8 courses, resp., could be evaluated. Both modalities led to significant improvement of the skin lesions. During the course of treatment, there were no significant differences between the two regimens with regard to both the area of skin involvement and the scores of semiquantitative evaluation of infiltration, erythema, and scaling.

    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 a very common disease of the pilosebaceous unit of the human skin. The pathological processes of acne are not fully understood. To gain further insight sebaceous follicular casts were extracted from 18 healthy and 20 acne-affected individuals by cyanoacrylate-gel biopsies and further processed for mass spectrometry analysis, aiming at a proteomic analysis of the sebaceous follicular casts. Human as well as bacterial proteins were identified. Human proteins enriched in acne and normal samples were detected, respectively. Normal follicular casts are enriched in proteins such as prohibitins and peroxiredoxins which are involved in the protection from various stresses, including reactive oxygen species. By contrast, follicular casts extracted from acne-affected skin contained proteins involved in inflammation, wound healing and tissue remodeling. Among the most distinguishing proteins were myeloperoxidase, lactotransferrin, neutrophil elastase inhibitor and surprisingly, vimentin. The most significant biological process among all acne-enriched proteins was ‘response to a bacterium’. Identified bacterial proteins were exclusively from Propionibacterium acnes. The most abundant P. acnes proteins were surface-exposed dermatan sulphate adhesins, CAMP factors, and a so far uncharacterized lipase in follicular casts extracted from normal as well as acne-affected skin. This is a first proteomic study that identified human proteins together with proteins of the skin microbiota in sebaceous follicular casts. PMID:25238151

    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. PMID:26705192

    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.

  15. 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.

    Standard systemic therapeutic agents used in acne include oral antimicrobials, isotretinoin, and hormonal agents. Appropriate patient selection is the key to decide when to use hormonal agents as first-line therapy as well as to achieve optimal results. Indications of hormonal therapy in acne in girls and women include proven ovarian or adrenal hyperandrogenism, recalcitrant acne, acne not responding to repeated courses of oral isotretinoin, acne tarda, polycystic ovary syndrome, or the presence of clinical signs of hyperandrogenism such as androgenic alopecia or the presence of the seborrhea, acne, hirsutism, alopecia syndrome. We describe the hormonal agents currently available for acne treatment, discuss their indications and contraindications, and address the question of whether they may be used as a first-line therapy in acne.

    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. PMID:23691509

    Propionibacterium acnes is a key pathogenic factor in the development of acne. Antibiotics are the first choice of treatment for mild-to-moderate, mixed, papular/pustular, and moderate nodular acne, and an alternative choice in severe, nodular/conglobate acne. The emergence of resistance to the currently available antibiotics poses a serious set-back to this algorithm, and the reduced arsenal can diminish efficacy of treatment. This emerging situation should catalyze innovations in dermatology; for example, newer drugs and technologies such as next-generation antibiotics with excellent potency and low propensity to develop resistance, rapid diagnostic platforms to select responders and nonresponders, and delivery technologies that target the bacteria. Such innovations can dramatically expand the arsenal for dermatologists in the management of acne. PMID:27416310

He presented 6 months after the second surgery with persistent intraocular inflammation in both eyes. Cultures from both eyes grew Propionibacterium acnes and he responded well to treatment. Suspicion for delayed-onset post-operative endophthalmitis must remain high in uveitis cases that fail to resolve with anti-inflammatory treatments. The authors believe this is the first reported case of bilateral sequential P. acnes exogenous endophthalmitis. PMID:27220771

    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. PMID:26472097

    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.

    Forbidden foods? "The first law of dietetics seems to be: If it tastes good, it's bad for you" (Isaac Asimov, Russian-born biochemist and science fiction writer). This was essentially the Magna Carta for dermatologists of the 1950s: anything coveted by the teenage palate was suspect for morning after acne. Today, half a century later, although the slant has shifted away for this line of thinking in our dermatologic textbooks, several articles on the beliefs and perceptions of acne patients showed that nothing much has changed and that they expect us to give them detailed instructions of what "acne-related" foods they should avoid. In one such study(1), diet was the third most frequently implicated factor (after hormones and genetics) as the cause of the disease, with 32% of the respondents selecting diet as the main cause, and 44% thinking that foods aggravate acne. In another study that analyzed knowledge about causes of acne among English teenagers, 11% of the responders blamed greasy food as the main cause of the disease(2), whereas in another study found that 41% of final-year medical students of the University of Melbourne chose diet as an important factor of acne exacerbation on a final examination.(3) PMID:15556724

    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

    Severe nodular acne, defined as grade 4 or 5 acne on the Investigator's Static Global Assessment scale, is a skin condition characterized by intense erythema, inflammation, nodules, cysts, and scarring. Both the well known risk of physical scarring and the more recent recognition that acne can be a chronic, psychologically distressing disease with significant adverse effects on a patient's quality of life, have prompted earlier, more aggressive treatment with more effective medications, in the hope of preventing progression to more severe, nodular forms of the disease. Oral antibacterials, primarily tetracyclines, have long been the first-line therapy for severe nodular acne, which frequently remained refractory to therapy. However, concerns of antibacterial adverse effects, patient adherence, and antimicrobial resistance prompted the search for alternate therapies and combinations thereof in order to target the multifactorial pathogenesis of the disease. Isotretinoin, an oral retinoid introduced in 1982, has since become the gold standard therapy in severe acne and has revolutionized its treatment. Several adjunctive agents exist. Oral antibacterials are indicated as an alternative for patients with severe acne who cannot tolerate oral retinoids, or for whom a contraindication exists. In order to prevent bacterial resistance, antibacterials should always be used in combination with benzoyl peroxide, a nonantibiotic antimicrobial agent with anti-inflammatory activity. Topical retinoids are often added to this regimen. In women, hormonal agents, which include oral contraceptives, spironolactone, and oral corticosteroids, and, in Europe, cyproterone acetate, may be used as monotherapy or concomitantly with isotretinoin. For rapid treatment of inflammatory nodules, intralesional corticosteroids are effective. These treatment modalities have been studied, refined, and combined in novel ways in order to target the multifactorial pathogenesis of the disease, and in this

    The synergistic effect of temperature (25-65 °C) and total specific energy input (0.55-1.11 kWh kgDW(-1)) by pulsed electric field (PEF) on the release of intracellular components from the microalgae Chlorella vulgaris was studied. The combination of PEF with temperatures from 25 to 55 °C resulted in a conductivity increase of 75% as a result of cell membrane permeabilization. In this range of temperatures, 25-39% carbohydrates and 3-5% proteins release occurred and only for carbohydrate release a synergistic effect was observed at 55 °C. Above 55 °C spontaneous cell lysis occurred without PEF. Combined PEF-temperature treatment does not sufficiently disintegrate the algal cells to release both carbohydrates and proteins at yields comparable to the benchmark bead milling (40-45% protein, 48-58% carbohydrates).

    Affecting over 80% of adolescents, acne is a widespread condition with substantial negative physical and emotional effects, and significant societal cost. Cleansing the acne patient involves several considerations, including matching skin type to the right type of cleanser, optimal times and methods of cleansing, treating parts of the body other than the face, and patient perceptions of the cause and treatment of acne. Moisturizing prevents and alleviates skin irritation, soothing the skin by slowing the evaporation of water. Many liquid face cleansers also moisturize, which may be all that is needed for a patient with oily skin. Protection from sun and environmental damage is important for all patients. While sunscreens are often irritants, the best options for young, oily, acne-prone skin tend to have a water or light liquid base. Moisturizing sunscreens are appropriate for patients with dry, sun-damaged skin, as well as those who wear makeup, have other skin diseases, or are easily irritated by products. Overall, treating acne patients should include education in patient-friendly terms and promoting healthy daily skin care practices, including cleansing and protection against environmental damage.

    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 benefits from a series of treatments. The introduction of isotretinoin was a therapeutic breakthrough which considerably improved both the evolution and the prognosis of the disease. Indications of this retinoid kept changing over the past twenty years. New clinical conditions emerged including the management of disease recurrences. The daily dosages must be selected according to the type of acne, the gender of the patient and the pharmaco-economical implications. Teratogenicity must never be neglected as it represents the dreadful adverse event of the drug. A European Directive currently marks out the way to use this retinoid. PMID:18561765

    Background: Elevation of C-reactive protein (CRP) has been reported to occur in psoriasis, urticaria, acne, rosacea and many other dermatological and nondermatological conditions. Chronic systemic inflammation has been implicated in the development of neuropsychiatric/degenerative disorders, atherosclerosis, coronary artery disease, diabetes mellitus and even carcinogenesis. The present study is designed to determine whether the level of inflammation created by acne vulgaris could be high enough to raise the serum levels of high-sensitive CRP. Materials and Methods: Forty-two patients with moderate and severe acne vulgaris were enrolled, along with 44 age and sex matched healthy blood donors as controls. Hypersensitive-CRP (Hs-CRP) was measured in both groups. Results: Hypersensitive-C-reactive protein levels in the case group varied between 0 and 28.1 μg/ml with an average of 2.24 ± 4.87 μg/ml (mean ± standard deviation) and a median of 0.6 μg/ml (interquartile range [IQR] =0.3, 1.4 μg/ml). Hs-CRP levels of the control group varied between 0 and 14 μg/ml with an average of 3.12 ± 3.67 μg/ml and a median of 1.5 μg/ml (IQR = 0.55, 5.0 μg/ml). No significant difference of Hs-CRP level between the two groups was seen (t = –0.961, 95% confidence interval: Lower = –2.6942, upper = 0.9377; P = 0.339). Additionally, no significant difference in the level of Hs-CRP was noted between the moderate and severe acne groups (95% confidence interval: Lower = –5.2495, upper = 1.6711; P = 0.165). Conclusion: Acne vulgaris, even in its severe grades (excluding acne fulminans and acne conglobata), does not induce significant inflammation at the systemic level. PMID:26225329

    Phytohemagglutin (PHA), purified from red kidney beans (Phaseolus vulgaris) by Affi-Gel blue affinity chromatography, was subjected to ultrahigh-pressure (UHP) treatment (150, 250, 350, and 450 MPa). The purified PHA lost its hemagglutination activity after 450 MPa treatment and showed less pressure tolerance than crude PHA. However, the saccharide specificity and α-glucosidase inhibition activity of the purified PHA did not change much after UHP treatment. Electrophoresis staining by periodic acid-Schiff (PAS) manifested that the glycone structure of purified PHA remained stable even after 450 MPa pressure treatment. However, electrophoresis staining by Coomassie Blue as well as circular dichroism (CD) and differential scanning calorimetry (DSC) assay proved that the protein unit structure of purified PHA unfolded when treated at 0-250 MPa but reaggregates at 250-450 MPa. Therefore, the hemagglutination activity tends to be affected by the protein unit structure, while the stability of the glycone structure contributed to the remaining α-glucosidase inhibition activity.

    Common warts (verruca vulgaris) are one of the most common problems encountered in dermatology and may present a difficult treatment dilemma, as no particular therapy has demonstrated complete efficacy. Intralesional injection of purified Candida antigen has produced impressive treatment results in small prospective and retrospective studies and is thought to produce its effect through stimulation of a cell-mediated immune response. We report a retrospective study of adult and pediatric patients treated with Candida antigen therapy in clinical practice. Of the 100 patients treated, 80% responded to therapy: 39% demonstrated a complete response and 41% demonstrated a partial response. In addition, 6 out of 7 immunocompromised patients who were treated demonstrated a partial or complete response. Injections were generally well-tolerated and adverse events were minimal and short-lived. Our data indicate that intralesional Candida antigen therapy for cutaneous warts is an efficacious option in a clinical practice setting. The treatment may also be effective in immunosuppressed patients with cutaneous warts. Our results add to the literature one of the largest retrospective series reported to date and treatment outcomes are similar to previously reported studies evaluating this therapeutic modality.

    Hormonal therapy is an important component in the treatment of women with acne who may or may not have elevated serum androgens. The mainstays of hormonal therapy include oral contraceptives and antiandrogens such as cyproterone acetate, flutamide or spironolactone. Recent research over the past several years has unraveled some of the details regarding the way that the skin and sebaceous glands synthesize and metabolize hormones. The knowledge gained from this work may provide an impetus for future drug discovery in the hormonal treatment of acne and lead to improvements in the care of our patients with acne. PMID:12566806

    This research was conducted to investigate two main aims; the first aim was to find if there is a relationship between insulin resistance (IR) and retinol binding protein 4 (RBP4). The second aim was to use berberis vulgaris extract and vitamin A as protective and/or curative agents against insulin resistance. IR was developed by feeding the female rats a high fat diet (HFD) for six weeks then treating or protecting them with b. vulgaris extract (0.2 g/Kg body weight) or vitamin A (12.8μg/Kg/day) for two weeks. HFD intake elevated insulin level and RBP4 expression that associated with hyperglycemia and hyperlipidemia. Co-administration of vitamin A and B. vulgaris extracts reduced blood glucose level, insulin, body weight and RBP4 expression before, during and after HFD. Furthermore, vitamin A reduced the blood glucose, triglycerides (TG) and cholesterol levels. IR syndrome associated with the RBP 4 alteration that gives high indication about the role of RBP4 expression in the IR progression and development. Furthermore, the treatment with vitamin A and/or b. vulgaris alleviated the IR syndrome through the action on RBP4 and Insulin secretion. On the other hand, vitamin A must be avoided for the predisposed IR and prediabetic patients. PMID:24191325

    Acne vulgaris is a chronic dermatological disorder that affects the majority of teenagers in the Western world. Topical therapy is widely used to treat mild-moderate acne and is known as well-tolerated thanks to its low systemic toxicity, although associated to skin adverse effects. Acne seems to be associated also to an intrinsic alteration of the epidermal barrier, regarding both the upper and the follicular stratum corneum that promotes the onset of such local side effects. The commonest one is irritant contact dermatitis, an event of frequent observation occurring with erythema, burning, dryness, scaling, and itching, usually characterized by low severity and limited duration. Among topical acne drugs, retinoids are the most irritating ones. Another side effect is allergic contact dermatitis: it is rare and mainly associated to benzoyl peroxide. PMID:26302055

    Salicylic acid (SA) is a beta hydroxy acid and has multifunctional uses in the treatment of various diseases in skin such as acne, psoriasis, and photoaging. One problem often cited as associated with salicylic acid is that it can be quite irritating at pH 3-4, where it exhibits the highest activity in the treatment of skin diseases. We have identified strategies to control the irritation potential of salicylic acid formulations and have focused on hydroalcoholic solutions used in acne wipes. One strategy is to control the penetration of SA into the skin. Penetration of the drug into various layers of skin, i.e., epidermis, dermis, and receptor fluid, was measured using a modified Franz in vitro diffusion method after various exposure times up to 24 hours. A polyurethane polymer (polyolprepolymer-15) was found to be an effective agent in controlling delivery of SA. In a dose-dependent fashion it targeted delivery of more SA to the epidermis as compared to penetration through the skin into the receptor fluid. It also reduced the rapid rate of permeation of a large dose of SA through the skin in the first few hours of exposure. A second strategy that proved successful was incorporation of known mild nonionic surfactants like isoceteth-20. These surfactants cleanse the skin, yet due to their inherent mildness (because of their reduced critical micelle concentration and monomer concentration), keep the barrier intact. Also, they reduce the rate of salicylic acid penetration, presumably through micellar entrapment (either in solution or on the skin surface after the alcohol evaporates). Cumulative irritation studies showed that targeting delivery of SA to the epidermis and reducing the rapid early rate of penetration of large amounts of drug through the skin resulted in a reduced irritation potential. In vivo irritation studies also showed that the surfactant system is the most important factor controlling irritancy. SA delivery is secondary, as formulations with less

    Isotretinoin is a remarkably effective drug for severe, recalcitrant acne vulgaris. Soon after the drug's release in the early 1980s, a number of important adverse effects were reported subsequently leading to a variety of medical and medicolegal controversies. Three of these controversies will be highlighted concerning the putative role of isotretinoin in (1) depression and suicide, (2) inflammatory bowel disease, and (3) iPledge and pregnancy prevention programs. It appears that a very small subset of patients receiving isotretinoin for acne are at risk for depression, which is very manageable provided there is adequate patient awareness of the possibility, maximum communication between the patient and physician, and cessation of therapy if clinically important depression occurs (after which the depression rapidly resolves in a week or less). Multiple controlled studies actually suggest a very favorable effect of isotretinoin on depression and anxiety common in the population requiring isotretinoin. With regard to inflammatory bowel disease, in just one study, only ulcerative colitis association with isotretinoin reached statistical significance. The actual incidence of this association is strikingly low. Finally, it is clear that even the most recent pregnancy prevention program (iPledge) is no more successful than prior programs; there will likely always be a small number of female patients becoming pregnant while receiving isotretinoin for acne vulgaris.

    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. PMID:25372257

    BACKGROUND Inflammation is commonly observed in radical prostatectomy specimens, and evidence suggests that inflammation may contribute to prostate carcinogenesis. Multiple microorganisms have been implicated in serving as a stimulus for prostatic inflammation. The pro-inflammatory anaerobe, Propionibacterium acnes, is ubiquitously found on human skin and is associated with the skin disease acne vulgaris. Recent studies have shown that P. acnes can be detected in prostatectomy specimens by bacterial culture or by culture-independent molecular techniques. METHODS Radical prostatectomy tissue samples were obtained from 30 prostate cancer patients and subject to both aerobic and anaerobic culture. Cultured species were identified by 16S rDNA gene sequencing. Propionibacterium acnes isolates were typed using multilocus sequence typing (MLST). RESULTS Our study confirmed that P. acnes can be readily cultured from prostatectomy tissues (7 of 30 cases, 23%). In some cases, multiple isolates of P. acnes were cultured as well as other Propionibacterium species, such as P. granulosum and P. avidum. Overall, 9 of 30 cases (30%) were positive for Propionibacterium spp. MLST analyses identified eight different sequence types (STs) among prostate-derived P. acnes isolates. These STs belong to two clonal complexes, namely CC36 (type I-2) and CC53/60 (type II), or are CC53/60-related singletons. CONCLUSIONS MLST typing results indicated that prostate-derived P. acnes isolates do not fall within the typical skin/acne STs, but rather are characteristic of STs associated with opportunistic infections and/or urethral flora. The MLST typing results argue against the likelihood that prostatectomy-derived P. acnes isolates represent contamination from skin flora. PMID:23184509

    We present a case of Farmer's lung with antibodies to Thermoactinomyces vulgaris and Aspergillus fumigatus. A 56-year-old male patient with an atopic family medical history came to our hospital complaining of cough, dyspnea, fever, asthenia and anorexia. His condition worsened after being exposed to cereal powder, becoming symptomatic after 20 minutes or on occasion after 6 hours. Physical examination showed basal crepitant rales in lung auscultation. The radiograph of the thorax showed a bilateral interstitial reticulo-nodular pattern. An obstructive pattern was found on functional respiratory examination. There was also a slight restriction along with the decrease of the VC and a significant reversal of the M.M.E.F. with anticholinergics. The tests for intradermal cutaneous allergies were positive after 20 minutes and for Aspergillus fumigatus Niger and Terreus (Bencard) after 6 hours. With immunoelectrophoresis and double diffusion, precipitation bands in the presence of Aspergillus fumigatus and Thermoactinomyces, were detected. IgG and IgE were high-1570 mg% and 1000 U/ml respectively. The histological study of the transbronchial biopsy showed dilatation of the alveolar septum caused by a lymphocytic infiltration with fragments of collagenous fibres. In bronchoalveolar lavage there was a predominance of lymphocytes and histiocytes. After exertion, arterial blood gases showed desaturation with hypoxemia. The static lung volumes and the flow and diffusion of carbon monoxide (CO) showed a moderate decrease of vital capacity, with the total lung capacity being below normal. Diffusion was markedly attenuated. The provocation test by indirect bronchial inhalation using cereal powder (Alfalfa) was positive. After six hours dyspnea, cough and leukocytosis appeared with an outbreak of fever and an increase in the erythrocyte sedimentation rate.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3909794

    Propionibacterium acnes (P. acnes) cause inflammatory acne and play an important role in the pathogenesis of acne by inducing inflammatory mediators. P. acnes contributes to the inflammatory responses of acne by activating inflammatory cells, keratinocytes and sebocytes to secrete pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and IL-8. Bee venom has traditionally been used in the treatment of certain immune-related diseases. However, there has not yet been a robust trial to prove the therapeutic effect of bee venom in skin inflammation. The aim of the present study was to investigate anti-inflammatory properties of bee venom in skin inflammation induced by P. acnes using keratinocytes (HaCaT) and monocytes (THP-1). P. acnes is known to stimulate the production of pro-inflammatory cytokines such as IL-1, IL-8, IL-12 and TNF-α. In the present study, the production of interferon-γ (IFN-γ), IL-1β, IL-8 and TNF-α was increased by P. acnes treatment in HaCaT and THP-1 cells. By contrast, bee venom effectively inhibited the secretion of IFN-γ, IL-1β, IL-8 and TNF-α. Furthermore, P. acnes treatment activated the expression of IL-8 and toll-like receptor 2 (TLR2) in HaCaT cells. However, bee venom inhibited the expression of IL-8 and TLR2 in heat-killed P. acnes. Based on these results, it is concluded that bee venom has an effective anti-inflammatory activity against P. acnes in HaCaT and THP-1 cells. Therefore, we suggest that bee venom is an alternative treatment to antibiotic therapy of acne. PMID:25872535

    Objectives To determine the frequency of Staphylococcus aureus colonization among patients with acne and to compare the susceptibility patterns between the patients who are using antibiotics and those who are not using antibiotics. Design Survey (cross-sectional) study of patients treated for acne. Setting Dermatology outpatient office practice Participants The study included 83 patients who were undergoing treatment and evaluation for acne. Main Outcome Measure Colonization of the nose or throat with S aureus. Results A total of 36 of the 83 participants (43%) were colonized with S aureus. Two of the 36 patients (6%) had methicillin-resistant S aureus; 20 (56%) had S aureus solely in their throat; 9 (25%) had S aureus solely in their nose; and 7 (19%) had S aureus in both their nose and their throat. When patients with acne who were antibiotic users were compared with nonusers, the prevalence odds ratio for the colonization of S aureus was 0.16 (95% confidence interval [CI], 0.08–1.37) after 1 to 2 months of exposure and increased to 0.52 (95% CI, 0.12–2.17) after 2 months of exposure (P =.31). Many of the S aureus isolates were resistant to treatment with clindamycin and erythromycin (40% and 44%, respectively), particularly the nasal isolates. Very few showed resistance rates (<10%) to treatment with tetracycline antibiotics. Conclusion Unlike current dogma about the long-term use of antimicrobial agents, the prolonged use of tetracycline antibiotics commonly used to treat acne lowered the prevalence of colonization by S aureus and did not increase resistance to the tetracycline antibiotics.

    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. PMID:7825645

    Acne is one of the most frequent skin disorders that occurs in puberty, but often adults also have acne. The most important factors responsible for acne are elevated production of sebum by hyperactive sebaceous glands and blockage of the follicle because of hyperkeratosis [14]. The third etiopathogenic factor of acne is excessive microflora reproduction [8]. The most significant bacterium that is responsible for formation of skin lesions is Propionibacterium acnes, a rod-shaped Gram-positive and aerotolerant anaerobic bacterium. It is estimated that P. acnes is responsible for acne in approximately 80% of people aged 11 to 30 [27,40]. Even healed skin lesions can often cause skin discolorations and scar formation [51]. Exfoliating chemical substances that are commonly used in dermatology and cosmetology are organic acids. Exfoliating treatment using organic acids is called "chemical peeling" and consists of controlled application of those substances on the skin [38]. The depth of exfoliation depends on organic acid concentration, type of substance and contact time with the skin [41]. Using exfoliating agents seems to be helpful in excessive keratinization - one of several factors responsible for acne. Moreover, epidermis exfoliation is a popular method of removing skin discoloration [22]. Considering chemical structure, exfoliating substances that are most often used in cosmetology contain alpha-hydroxyacids (glycolic acid, lactic acid, mandelic acid and citric acid), beta-hydroxyacids (salicylic acid) and other organic acids, such as trichloroacetic acid and pyruvic acid [47]. In this article, a literature review of use of organic acids in acne and skin discoloration therapy is presented. PMID:25811473

  10. Dietary intervention in acne

    PubMed Central

    Melnik, Bodo

    2012-01-01

    The purpose of this paper is to highlight the endocrine signaling of Western diet, a fundamental environmental factor involved in the pathogenesis of epidemic acne. Western nutrition is characterized by high calorie uptake, high glycemic load, high fat and meat intake, as well as increased consumption of insulin- and IGF-1-level elevating dairy proteins. Metabolic signals of Western diet are sensed by the nutrient-sensitive kinase, mammalian target of rapamycin complex 1 (mTORC1), which integrates signals of cellular energy, growth factors (insulin, IGF-1) and protein-derived signals, predominantly leucine, provided in high amounts by milk proteins and meat. mTORC1 activates SREBP, the master transcription factor of lipogenesis. Leucine stimulates mTORC1-SREBP signaling and leucine is directly converted by sebocytes into fatty acids and sterols for sebaceous lipid synthesis. Over-activated mTORC1 increases androgen hormone secretion and most likely amplifies androgen-driven mTORC1 signaling of sebaceous follicles. Testosterone directly activates mTORC1. Future research should investigate the effects of isotretinoin on sebocyte mTORC1 activity. It is conceivable that isotretinoin may downregulate mTORC1 in sebocytes by upregulation of nuclear levels of FoxO1. The role of Western diet in acne can only be fully appreciated when all stimulatory inputs for maximal mTORC1 activation, i.e., glucose, insulin, IGF-1 and leucine, are adequately considered. Epidemic acne has to be recognized as an mTORC1-driven disease of civilization like obesity, type 2 diabetes, cancer and neurodegenerative diseases. These new insights into Western diet-mediated mTORC1-hyperactivity provide a rational basis for dietary intervention in acne by attenuating mTORC1 signaling by reducing (1) total energy intake, (2) hyperglycemic carbohydrates, (3) insulinotropic dairy proteins and (4) leucine-rich meat and dairy proteins. The necessary dietary changes are opposed to the evolution of

    Background: Acne is typically regarded as an adolescent disease. A significant body of literature suggests a post-adolescent or adult form of acne. Female patients are known to experience perimenstrual acne flares, the exact prevalence of which is unknown. Objective: To establish a pattern of perimenstrual acne flare in adult women in order to better characterize the disorder. Methods: Subjects aged 18 and over were recruited during previously scheduled visits with their dermatologist at Mount Sinai Hospital in New York. An anonymous survey was distributed to women who reported their first menses at least six months earlier and had a complaint of acne within the last 30 days. Women <18 years of age and postmenopausal women were excluded from the study population. Results: Participants included women 18- to 29-years old (67%) and women 30- to 49-years old (33%). The ethnicity of respondents was Caucasian (50%), African American (20%), Latino (19%), Asian (5%), and Other (6%). The majority of participants with perimenstrual acne reported the onset of acne between the ages of 12 and 18 years. Sixty-five percent of participants reported that their acne symptoms were worse with their menses. Of those who reported perimenstrual acne symptoms, 56 percent reported worsening symptoms in the week preceding their menses, 17 percent reported worsening symptoms during their menses, three percent reported worsening symptoms after their menses, and 24 percent reported worsening symptoms throughout their cycle. Thirty-five percent of patients with perimenstrual acne reported oral contraceptive pill use. Conclusion: A significant number of adult women have perimenstrual acne symptoms. This study has proven to be useful in characterizing perimenstrual acne flare and is one of the first qualitative documentations of the presence and degree of this disorder. PMID:25161758

    Background Psychological stress is an important factor of acne pathogenesis. Stress related production of hormones, cytokines and neuropeptides may result in the chronic course and exacerbations of the disease. Objective The aim of the study was to evaluate the relationship between acne severity, intensity of emotional stress and serum concentration of substance P (scSP), to compare the intensity of adversities, psychological stress and scSP in acne patients with healthy controls and to compare coping techniques for stress. Methods The study consisted of 80 patients. Emotional stress was analyzed with the use of social readjustment rating scale, whereas the methods of coping with stress were assessed with the coping inventory for stressful situation questionnaire. The blood concentration of substance P was analyzed by enzyme-linked immunosorbent assay method in a group of 40 patients with acne vulgaris and in control subjects. Results There was no statistically significant difference between the severity of acne and the intensity of stress. Acne patients presented a higher average scSP than the controls. No statistically significant correlation was observed between the severity of acne and scSP; however, the intensity of stress correlated with scSP in the control group. The evaluation of methods of coping with stress showed significantly higher rate for the avoidance-oriented coping among acne patients. Conclusion The number of stressful events is not a factor that determines the severity of acne. The course of the disease may depend on tolerance to stress and methods of coping with stress.

    Staphylococcus epidermidis (S. epidermidis) plays a critical role in modulating cutaneous inflammatory responses in skin. Although S. epidermidis has been shown to co-colonize with Propionibacterium acnes (P. acnes) in acne lesions, it is unclear whether S. epidermidis is involved in the regulation of P. acnes-induced inflammatory responses. In this study, we demonstrated that S. epidermidis inhibited P. acnes-induced inflammation in skin. P. acnes induced the expression of interleukin-6 and tumor necrosis factor-α via the activation of toll-like receptor (TLR) 2 in both keratinocytes and mouse ears. Staphylococcal lipoteichoic acid activated TLR2 to induce miR-143 in keratinocytes, and miR-143, in turn, directly targeted 3' UTR of TLR2 to decrease the stability of TLR2 mRNA and then decreased TLR2 protein, thus inhibiting P. acnes-induced proinflammatory cytokines. The inhibitory effect of miR-143 was further confirmed in vivo as the administration of miR-143 antagomir into mouse ears abrogated the inhibitory effect of lipoteichoic acid on P. acnes-induced inflammation in skin. Taken together, these observations demonstrate that staphylococcal lipoteichoic acid inhibits P. acnes-induced inflammation via the induction of miR-143, and suggest that local modulation of inflammatory responses by S. epidermidis at the site of acne vulgaris might be a beneficial therapeutic strategy for management of P. acnes-induced inflammation.

Compared, with teenage acne, severe acne can be distinguished by its late out break, its monstrous nature and its larger surface area. Amineptine has been found (or its metabolites) in the plasma, the urine. The treatment consists in the stopping of the drug addiction, combined with the prescription of isotretinoin. PMID:1839203

    In industrialized countries acne presents as an epidemic disease of civilization affecting sebaceous follicles of adolescents and young adults, associated with increased body mass index and insulin resistance. "Western style" diet, characterized by high glycaemic load and increased consumption of insulinotropic milk proteins, plays an important role in acne pathogenesis. On the cellular level, nutrient-derived metabolic signals are sensed by the metabolic transcription factor FoxO1 and integrated by the regulatory kinase mTORC1. mTORC1, the central hub of protein- and lipid biosynthesis, cell growth and proliferation, is activated by insulin, IGF-1 and branched-chain essential amino acids, especially leucine. The understanding of Western diet-mediated nutrient signalling with over-activated mTORC1 offers a reasonable approach for dietary intervention in acne by lowering glycaemic load and consumption of milk and milk products. A suitable diet attenuating increased mTORC1 activity is a Palaeolithic-like diet with reduced intake of sugar, hyperglycaemic grains, milk and milk products but enriched consumption of vegetables and fish.

  19. Acne: effect of hormones on pathogenesis and management.

    In the pathogenesis of acne, androgen hormones play a crucial role. In the treatment of acne, hormonal therapies provide valuable alternatives to standard modalities in selected women. Although numerous factors contribute to the development of acne, the requirement for androgens is absolute and is one that allows for effective treatments in women through inhibition of androgen expression. The two prerequisites for androgen expression at the level of the pilosebaceous unit are the presence of androgen in the form of either testosterone or dihydrotestosterone; and functioning androgen receptors. A third component may be the metabolism of androgen precursors to active androgens within pilosebaceous units. Hormonal treatment of hyperandrogenism (acne, hirsutism, androgenetic alopecia) such as that seen in polycystic ovary syndrome, centers on reduction of circulating androgen levels and androgen receptor blockade. Combination oral contraceptives represent the primary treatment modality for reducing circulating androgens from ovarian and, to a lesser degree, adrenal sources. Newer formulations may also have clinically significant androgen receptor blocking and 5alpha-reductase inhibiting effects. Newer oral contraceptives have high safety profiles and are used widely internationally for this purpose. Androgen receptor blockers currently in use include spironolactone, cyproterone acetate, and flutamide. Androgen receptor blockers are frequently combined with oral contraceptives to achieve optimal results in selected women. In women with adrenal hyperplasia, low-dose corticosteroids may be added to reduce adrenal androgen precursors. Inhibition of enzymes of androgen metabolism in the pilosebaceous unit remain largely investigational in the treatment of acne, although the benefit of 5alpha-reductase (type 2) inhibition is established in androgenetic alopecia in men. This article reviews the essentials of hormonal influence in acne pathogenesis, discusses the hormonal

    When administered intramuscularly, the designer antibacterial peptide dimer A3-APO is highly efficacious in mouse models of Acinetobacter baumannii and Staphylococcus aureus burn infections. Here we compared the efficacy of A3-APO and its monomeric metabolite in mouse models of S. aureus and Propionibacterium acnes intradermal infections following administration as intramuscular (i.m.) or topical treatments. In the animal models, either (i) the ears of CD-1 mice were infected with P. acnes or (ii) S. aureus was injected into burn wounds inflicted to the back. A3-APO or the monomer were injected intramuscularly at 5 mg/kg one to three times or were applied three times as 1% local treatment in phosphate-buffered saline or Vaseline(®). Despite being inactive against the strains in vitro, in vivo the skin conditions of the mice were dramatically improved upon peptide treatment regardless of dosing frequency, administration mode or drug valency. In the P. acnes study, A3-APO statistically significantly reduced ear thickness and ear bacterial counts. The amount of ear connective tissue and epithelial macrophages correlated with therapeutic success. Bacterial load in the lesions was more representative of physical improvement than ear dimensions. In the S. aureus model, both peptides eliminated wound bacteria from >10(7) CFU/mg to almost background levels, with monomer treatment being somewhat more successful. In conclusion, A3-APO and its monomeric metabolite very efficiently ameliorate resistant aerobic and anaerobic intradermal infections, but the protection is apparently not due to direct bacterial killing. Immunostimulatory and anti-inflammatory actions are likely involved. Nevertheless, topical and i.m. administrations are equally effective. PMID:24074727

    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.

    Background Acne is a chronic disease of the pilosebaceous unit that mainly affects adolescents. It is the most common dermatological problem, affecting approximately 80% of teenagers between 12 and 18 years of age. Diagnosis is clinical and is based on the patient’s age at the time the lesions first appear, and on its polymorphism, type of lesions, and their anatomical location. The right treatment for the right patient is key to treating acne safely. The aim of this investigational survey was to evaluate how Brazilian dermatologists in private practice currently manage acne. Materials and methods Dermatologists practicing in 12 states of Brazil were asked how they manage patients with grades I, II, III, and IV acne. Each dermatologist completed a written questionnaire about patient characteristics, acne severity, and the therapy they usually prescribe for each situation. Results In total, 596 dermatologists were interviewed. Adolescents presented as the most common acneic population received by dermatologists, and the most common acne grade was grade II. The doctors could choose more than one type of treatment for each patient, and treatment choices varied according to acne severity. A great majority of dermatologists considered treatment with drugs as the first alternative for all acne grades, choosing either topical or oral presentation depending on the pathology severity. Dermocosmetics were chosen mostly as adjunctive therapy, and their inclusion in the treatment regimen decreased as acne grades increased. Conclusion This survey illustrates that Brazilian dermatologists employ complex treatment regimens to manage acne, choosing systemic drugs, particularly isotretinoin, even in some cases of grade I acne, and heavily prescribe antibiotics. Because complex regimens are harder for patients to comply with, this result notably raises the question of adherence, which is a key factor in successful treatment. PMID:26609243

    Background: Acne vulgaris is known to impair many aspects of the quality of life (QoL) of its patients. Aim: To translate the Cardiff Acne Disability Index (CADI) from English into Hindi and to assess its validity and reliability in Hindi speaking patients with acne from India. Methods: Hindi version of CADI, translated and linguistically validated as per published international guidelines, along with a previously translated Hindi version of dermatology life quality index (DLQI) and a demographic questionnaire were administered to acne patients. The internal consistency reliability of the Hindi version of CADI and its concurrent validity were assessed by Cronbach's alpha co-efficient and Spearman's correlation co-efficient respectively. Construct validity was examined by factor analysis. Statistical analysis was carried out using the Statistical Package for the Social Sciences (SPSS) version 20 (SPSS Inc., Chicago, IL, USA) for Windows. Results: One hundred Hindi speaking patients with various grades of acne participated in the study. Hindi version of CADI showed high internal consistency reliability (Cronbach's alpha co-efficient = 0.722). Mean item-to-total correlation co-efficient ranged from 0.502 to 0.760. Concurrent validity of the scale was supported by a significant correlation with the Hindi DLQI. Factor analysis revealed the presence of two dimensions underlying the factor structure of the scale. Conclusion: Hindi CADI is equivalent to the original English version and constitutes a reliable and valid tool for clinical assessment of the impact of acne on QoL. PMID:26288422

    We report the in vitro inhibition of Propionibacterium acnes (P. acnes) by a bacteriocin-like inhibitory substance (BLIS-like substance) produced by Streptococcus salivarius (S. salivarius). Bacteriocins are proteinaceous substances produced by bacteria that are capable of inhibiting the growth of similar bacterial strains. Unlike classical antibiotics, they have a relatively narrow spectrum of killing activity, resulting in a reduction in the intensity of selection for resistance. These findings suggest that BLIS may potentially be used for its anti-P. acnes activity in the treatment of acne. PMID:17039652

    The psychological consequences of acne have been the subject of many studies. As a particularly visible skin disorder, acne complicates the daily lives of adolescents who are undergoing multiple transformations: physical, intellectual and emotional. While it is well established that acne can be responsible for depression and low self-esteem, it is likely that this impact is aggravated by the sociological evolution of adolescents in the 21st century. Understanding the codes of adolescents today (who can be characterized as being more concerned by their appearance than previous generations at the same age) allows us to optimize our medical approach to acne and facilitates treatment compliance and adherence.

    From the first reliable descriptions of acne in the early 19th century, dermatologists recognized it as a disease of the pilosebaceous follicle. Until the middle of the 20th century, they hypothesized that seborrhoea, follicular keratosis and microorganisms could be individually responsible for the acne lesions. Inflammation was only regarded as the final and inescapable step of the acne process. Although the importance of these factors has been reevaluated, recent works still regarded them as mandatory. In the 1970s, the onset of isotretinoin dramatically improved acne management. It also provided great opportunities for a better understanding of the pathogenic factors of acne. This study analyzes their genesis and development from the seminal contributions until recent advances. PMID:25228295

    The treatment of acne with combination therapy is commonplace with treatment aimed at sustained efficacy with minimal side effects, maximum adherence, and the avoidance of bacterial resistance. Combinations containing clindamycin and benzoyl peroxide have been shown to be effective, but the irritation caused by the concentration of benzoyl peroxide 5% in the more commonly used, fixed combinations can be limiting. In addition, surfactants, preservatives, and high levels of organic solvents, including alcohols, often used in combination with benzoyl peroxide, are potential irritants. An optimized formulation of clindamycin and benzoyl peroxide using a lower concentration of benzoyl peroxide (clindamycin-benzoyl peroxide 2.5% gel) has been developed without the use of surfactants or alcohol. It was recently introduced for the once-daily treatment of inflammatory and noninflammatory lesions in moderate-to-severe acne. Following a clinical program that studied more than 2,800 patients, clindamycin-benzoyl peroxide 2.5% was found to be highly effective and well tolerated. This review highlights the development of clindamycin-benzoyl peroxide 2.5% gel and the data from clinical trials.(J Clin Aesthetic Dermatol. 2009;2(5):44-48.). PMID:20729964

    Background: Increased reactive oxygen species (ROS) and lipid peroxidation are seen in many dermatologic disorders, for example, atopic dermatitis, psoriasis, vitiligo, acne vulgaris, pemphigus vulgaris (PV), lichen planus, and alopecia areata. ROS has an important role in the inflammation process. In PV, increased production of ROS leads to decline of antioxidants in plasma and red blood cells which results in oxidative stress. We aimed to evaluate the level of these antioxidants in PV patients and compare it to the controls. Materials and Methods: Among patients attending the dermatology clinics, 30 patients with PV, who had never been on treatment, were enrolled to the study. The control group consisted of 30 age- and sex-matched healthy non-smoker individuals. Venous blood was collected from the subjects for the evaluation of plasma levels of glutathione peroxidase, vitamin C, selenium, bilirubin, and uric acid. Results: Age mean and standard deviation of the patients (40.83, 12.74) was comparable to the controls (41.96, 13.08). Mean level of uric acid was significantly lower in PV patients compared to the controls (P = 0.006). Other antioxidants were not different between the two groups. Uric acid of the patients with mucosal involvement was significantly lower than patients with mucocutaneous involvement (P = 0.049). Limitations: The blood level of other antioxidants (e.g. malondialdehyde) was not evaluated. Conclusions: Uric acid as an antioxidant in our study had similar changes to previous studies in the field of other diseases but selenium, bilirubin, and glutathione peroxidase did not differ between patients and controls.

    Acne is a common disease especially among teenagers. It has a considerable psychological impact on affected individuals. The aim of this paper was to assess if the effect of acne on acne-related quality of life is correlated to acne clinical severity. 112 university female students attending the university medical clinics with acne complaints were examined. Cardiff Acne Disability Index (CADI) was used to assess acne-related quality of life, and global acne grading system (GAGS) was used to assess clinical severity of acne. There was no correlation between acne severity (GAGS scoring system) and quality of life impairment as assessed by CADI score (r = 0.145, P = .127). Additionally, CADI score did not correlate with disease duration or age of patients. We therefore conclude that acne clinical severity alone does not affect acne-related quality of life changes. Many other factors might play a role. PMID:20706683

    BACKGROUND Psoriasis is a common, chronic, recurrent, immune-mediated disorder of the skin and joints. It can have a significant negative impact on the physical, emotional and psychosocial wellbeing of affected patients. OBJECTIVES To measure improvement in health-related QoL (HRQoL) in Greek patients with psoriasis vulgaris after a month of treatment with calcipotriol-betamethasone dipropionate gel; and evaluate adherence to treatment parameters. METHODS The study included 394 psoriasis vulgaris patients from 16 private dermatological practices in Greece, all treated with calcipotriol-betamethasone dipropionate gel. They were evaluated at the first visit and after 4 weeks. Moreover, they completed the Dermatology Life Quality Index (DLQI), while other data such as disease severity, subjective symptoms and adherence, were collected. RESULTS At week 4, the DLQI median was reduced by 3.5 points from the baseline (p<0.001; baseline and week 4 median: 4.5 and 1.0 respectively). Pruritus and sleep disorders also improved (p<0.001). Furthermore, 90.1% of the subjects fully adhered to treatment, with a 97.1% mean level of compliance. CONCLUSIONS The convincing clinical results, with a distinct improvement in HRQoL, plus the high level of adherence due to its advantageous physical properties, make the calcipotriol-betamethasone dipropionate gel formulation an important, effective and well-tolerated topical therapy to treat psoriasis.

    Curcumin is a complementary therapy that may be helpful for the treatment of psoriasis due to its anti-inflammatory, antiangiogenic, antioxidant, and antiproliferative effects. In the present study we performed a randomized, double-blind, placebo-controlled clinical trial to assess the effectiveness of a bioavailable oral curcumin in the treatment of psoriasis. Sixty-three patients with mild-to-moderate psoriasis vulgaris (PASI < 10) were randomly divided into two groups treated with topical steroids and Meriva, a commercially available lecithin based delivery system of curcumin, at 2 g per day (arm 1), or with topical steroids alone (arm 2), both for 12 weeks. At the beginning (T0) and at the end of the therapy (T12), clinical assessment and immunoenzymatic analysis of the serum levels of IL-17 and IL-22 were performed. At T12, both groups achieved a significant reduction of PASI values that, however, was higher in patients treated with both topical steroids and oral curcumin than in patients treated only with topical steroids. Moreover, IL-22 serum levels were significantly reduced in patients treated with oral curcumin. In conclusion, curcumin was demonstrated to be effective as an adjuvant therapy for the treatment of psoriasis vulgaris and to significantly reduce serum levels of IL-22. PMID:26090395

    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. PMID:27001316

    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.

    The interdependencies of the two main processing parameters affecting "electroporation" (electric field strength and pulse duration) while using pulse duration in the range of milliseconds and microseconds on the permeabilization, inactivation, and extraction of pigments from Chlorella vulgaris was compared. While irreversible "electroporation" was observed above 4 kV/cm in the millisecond range, electric field strengths of ≥10 kV/cm were required in the microseconds range. However, to cause the electroporation of most of the 90 % of the population of C. vulgaris in the millisecond (5 kV/cm, 20 pulses) or microsecond (15 kV/cm, 25 pulses) range, the specific energy that was delivered was lower for microsecond treatments (16.87 kJ/L) than in millisecond treatments (150 kJ/L). In terms of the specific energy required to cause microalgae inactivation, treatments in the microsecond range also resulted in greater energy efficiency. The comparison of extraction yields in the range of milliseconds (5 kV, 20 ms) and microseconds (20, 25 pulses) under the conditions in which the maximum extraction was observed revealed that the improvement in the carotenoid extraction was similar and chlorophyll a and b extraction was slightly higher for treatments in the microsecond range. The specific energy that was required for the treatment in the millisecond range (150 kJ/L) was much higher than those required in the microsecond range (30 kJ/L). The comparison of the efficacy of both types of pulses on the extraction enhancement just after the treatment and after a post-pulse incubation period seemed to indicate that PEF in the millisecond range created irreversible alterations while, in the microsecond range, the defects were a dynamic structure along the post-pulse time that caused a subsequent increment in the extraction yield.

    Benzoyl peroxide (BPO) was introduced in the treatment of acne in 1934. Despite the fact that only few randomized trials have been published, BPO is considered the standard in topical acne treatment. Anaerobic bacteria are reduced by oxidative mechanisms and the induction of resistant strains is reduced. Topical formulations are available at concentrations of 2.5, 5, 10 and 20 %. The effect is dose-dependent, but the irritation increases with higher concentrations. Usually 5 % BPO is sufficient to control acne grade I-II. Due to its strong oxidative potential, patients should be advised that BPO may bleach colored and dark clothing, bedding and even hair. BPO is safe for use in pregnant and lactating females because it is degraded to benzoic acid. It is a cost-effective treatment for acne grade I-II. Patients with papulopustular acne grade I-II, particularly with marked inflammation, show satisfactory improvement with topical antibiotic treatment. The following compounds are available and effective: erythromycin, clindamycin and tetracycline (the latter being less frequently used). A review in 1990 suggested that topical tetracycline was ineffective in the treatment of acne. Along with eliminating Propionibacterium acnes, the main mechanism of topical antibiotics is their antiinflammatory effect. All three penetrate the epidermal barrier well and are similarly efficacious. Randomized trials have shown that in concentrations of 2-4 %, their effects are comparable to oral tetracycline and minocycline. Combination therapy with retinoids or benzoyl peroxide (BPO) increases efficacy. Retinoids increase penetration and reduce comedones, while topical antibiotics primarily address inflammation. One side effect of topical antibacterial treatment is an increase in drug-resistant resident skin flora with gram-negative microorganisms prevailing, which can lead to gram-negative folliculitis. All three antibiotics fluoresce under black light which may produce interesting

    Benzoyl peroxide was introduced as a basic treatment already in acne therapy 1934. The mechanism of action is the reduction of anaerobe bacteria by strong oxidation processes. No resistancies have been ever reported. BPO is available in 2.5, 5 and 10 % formulations. Its efficacy is slightly related to the strength of concentrations, but the side effect profile with burning, erythema and desquamation is increasing with concentrations. BPO 5% mostly is efficient enough to control acne of grades I to II according to the Kligman & Plewig classification. BPO my bleach clothes and hair. It is the most costeffective topical drug in acne of grades I-II. Inflammatory acne of the papular-pustular type I-II can also be treated by topical antibiotics such as erythromycin, clindamycin, and, less frequent and today not anymore recommended tetracyclines. Mechanism of action is not alone an antibacterial but anti inflammatory effect. The efficacy and penetration of the topical antibiotics between the groups are similar. Randomized studies have shown that concentrations of 2-4% are equivalent to oral tetracycline and minocycline in mild to moderate acne. Combinatory formulations with BPO and with retinoids enhance the efficacy significantly. Topical antibiotics plus BPO show less bacterial resistancies as topical antibiotics alone. Antibiotics should therefore not be used as monotherapy. Moreover gram negative folliculitis may develop. Azelaic acid is acting as an antimicrobial and can also reduce comedones. It can also be used in pregnancy and during the lactation period. PMID:20482689

    Aims To isolate and characterise phage which could lyse P. acnes and to formulate the phage into a delivery form for potential application in topical treatment of acne infection. Methods and Results Using standard phage isolation techniques, ten phage capable of lysing P. acnes were isolated from human skin microflora. Their genomes showed high homology to previously reported P. acnes phage. These phage were formulated into cetomacrogol cream aqueous at a concentration of 2.5x108 PFU per gram, and shown to lyse underlying P. acnes cells grown as lawn cultures. These phage formulations remained active for at least 90 days when stored at four degrees Celsius in a light protected container. Conclusions P. acnes phage formulated into cetomacrogol cream aqueous will lyse surrounding and underlying P. acnes bacteria, and are effective for at least 90 days if stored appropriately. Significance and Impact of the Study There are few reports of phage formulation into semi solid preparations for application as phage therapy. The formulation method described here could potentially be applied topically to treat human acne infections. The potential exists for this model to be extended to other phage applied to treat other bacterial skin infections. PMID:26964063

    Acne is a common inflammatory disease. Scarring is an unwanted end point of acne. Both atrophic and hypertrophic scar types occur. Soft-tissue augmentation aims to improve atrophic scars. In this review, we will focus on the use of dermal fillers for acne scar improvement. Therefore, various filler types are characterized, and available data on their use in acne scar improvement are analyzed. PMID:26491364

    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 presenting in adult women is commonly encountered in clinical practice. Many affected women have had acne during their teenaged years, have tried several therapies in the past, and are seeking effective treatment. Others are frustrated by the inexplicable emergence of acne as an adult when they never had it as a teenager. Both groups seek an explanation of why they have acne, are often psychosocially affected by its effects on appearance and self-esteem, and all are wanting effective and safe treatment. Clinicians are encouraged to connect favorably with each patient through careful history and physical examination and to consider underlying causes of androgen excess. Practical approaches to examination and laboratory evaluation are discussed. PMID:26682286

    The clinical and neuroimaging characteristics of brain infections related to Propionibacterium acnes are not well-characterized, making early diagnosis and treatment a challenge. More recently, life-threatening central nervous system infections with P. acnes are being reported with increasing frequency as complications of neurointerventional procedures. We present a rare case of P. acnes cerebritis that occurred as a sequela of bare platinum aneurysm coiling and a contaminant of percutaneous angiographic intervention. We include an extensive review of the literature describing the pathogenesis of P. acnes and neuro-radiological signs of brain infections related to this pathogen. PMID:25762004

    Benzoyl peroxide (BPO) is a widely used over-the-counter (OTC) topical acne treatment often used in combination with salicylic acid (SA) to achieve better comedone control than that achieved with BPO alone. MaxClarity™ is an OTC acne treatment system comprising BPO and SA in an aqueous foam delivery vehicle, VersaFoam AF™. This paper describes 2 open-label, single-arm studies conducted to assess the efficacy, safety, tolerability, and patient preference of MaxClarity in the treatment of mild, moderate, and severe acne. Subjects applied MaxClarity twice daily for 8 weeks in study 402 and for 12 weeks in study 405. Reductions in all lesion types were seen throughout both studies. At week 8 (study 402), there was a mean reduction from baseline of -56.9 ± 32.7% in total lesions in subjects with mild, moderate, or severe acne. At week 12 (study 405), there was a reduction from baseline of -61.6 ± 22.0% in total lesions in subjects with moderate or severe acne. Overall, both studies demonstrated that MaxClarity is a generally well tolerated and effective treatment for mild, moderate, and severe acne. PMID:23545906

    The authors report, for the first time in Bulgarian literature, a case of acne tetrad syndrome in a family. The patients were sisters who were found to have three of the four components of the syndrome: hidradenitis suppurativa, acne conglobata, and cysta pillaris. There was no evidence or anamnestic data for perifolliculitis capitis abscedens et suffodiens. In one of the sisters the syndrome showed a more precipitate clinical picture and was combined with other skin disorders (lichen ruber planus, neurodermitis circumscripta, hirsutismus). The patients had a familial predisposition to acne and pilar cycts. The complete blood analysis, all biochemical parameters, the cytogenetic analysis and hormonal status (testosterone and estrogens) showed no deviation from normal values. The patients did not report any disturbances during their menstrual cycles. The cellular immunity in one of the sisters was depressed. The patients and their children will be closely monitored.

    The anti-CD20 peripheral B-cell depleting monoclonal antibody, rituximab, has been shown to be a safe and effective treatment for refractory pemphigus vulgaris (PV), a potentially fatal autoimmune blistering disease. We report a patient who developed skin nodules and arthralgias following successful treatment of refractory PV with rituximab. Clinical, serological and histological findings were consistent with a diagnosis of sarcoidosis. The nodules promptly responded to treatment with corticosteroids, and resolved without recurrence when the medication was tapered several months later. The temporal onset of sarcoidosis following treatment with rituximab and the eventual resolution, coupled with the remarkable similarities between the B-cell immunological environment expected in our patient during the post-rituximab period and the immunological environment described in patients with idiopathic sarcoidosis, strongly implicates exposure to rituximab as the trigger for sarcoidosis development in our patient. We propose that rituximab-induced sarcoidal granulomas may be a rare adverse effect of treatment with this medication, providing further support for an important role of B cells in the pathogenesis of sarcoidosis. With better understanding of the circumstances surrounding sarcoidosis development following rituximab administration, this medication could potentially be used to induce sarcoidosis in animal research models to study the immunopathogenesis of this disease.

    Objective The purpose of this study was to assess the impact of acne on the quality of life. Its secondary objective was to assess the influence of gender of students and severity of symptoms on the quality of life.  Methods A cross sectional study was conducted on 100 students at Sultan Qaboos University (SQU) (40 males and 60 females) diagnosed with acne who attended the Student Clinic during a period of three months from September to December 2009. The Acne Quality Of Life index (Acne-QoL) questionnaire was used to assess the patient’s quality of life in four different domains: self-perception, social, emotional, and acne symptoms.  Results Acne affected all areas of the patients, quality of life with the emotional domain found to be the most affected. Overall, female patients reported more adverse QoL effects. The mean score for self-perception for female students was 2.5 and 2.8 for males (p=0.300). The role-social domain approached a significant difference between genders (p=0.078). There was a statistically significant correlation between severity of acne symptoms and the other three domains. The correlation was highest between acne symptoms score and self-perception score.  Conclusion This study showed that acne affects the quality of life of affected SQU students treated by primary care physicians at the Student Clinic. Therefore, physicians should take into account the effect of acne on the persons’ quality of life when individualizing treatment. PMID:25830000

    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. PMID:21198949

    Retinoids are used in the treatment of inflammatory skin diseases and malignancies, but studies characterizing the in vivo actions of these drugs in humans are lacking. Isotretinoin is a pro-drug for all-trans retinoic acid that can induce long-term remissions of acne; however, its complete mechanism of action is unknown. We hypothesized that isotretinoin induces remission of acne by normalizing the innate immune response to the commensal bacterium P. acnes. Compared to normal subjects, peripheral blood monocytes from acne patients expressed significantly higher levels of TLR-2 and exhibited significantly greater induction of TLR-2 expression following P. acnes stimulation. Treatment of patients with isotretinoin significantly decreased monocyte TLR-2 expression and subsequent inflammatory cytokine response to P. acnes by one week of therapy. This effect was sustained six months following cessation of therapy, indicating that TLR-2 modulation may be involved in the durable therapeutic response to isotretinoin. This study demonstrates that isotretinoin exerts immunomodulatory effects in patients and sheds light on a potential mechanism for its long-term effects in acne. The modulation of TLR-2 expression on monocytes has important implications in other inflammatory disorders characterized by TLR-2 dysregulation. PMID:22513780

    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.

    Current evidence suggests that post-adolescent acne in women is on the rise. Acne in this subgroup of patients commonly follows a specific pattern that can often be treatment resistant and/or prone to relapse, including after oral isotretinoin therapy. With a plethora of medications to choose from for acne treatment, many of which have been used in the past by patients without success, dermatology practitioners often find oral contraceptives and spironolactone to be of benefit in otherwise healthy adult females. Also, some of these patients may have concurrent hormonal anomalies such as polycystic ovarian syndrome or other underlying endocrine disorders, which should also be appropriately worked up by the clinician and managed accordingly. This article reviews some of the underlying pathophysiological factors, available treatment options, and screening guidelines to assist clinicians in the management of acne in adult females.

    A chemical derivative of the thiopeptide GE2270A, designated NAI003, was found to possess a substantially reduced antibacterial spectrum in comparison to the parent compound, being active against just a few Gram-positive bacteria. In particular, NAI003 retained low MICs against all tested isolates of Propionibacterium acnes and, to a lesser extent, against Enterococcus faecalis. Furthermore, NAI003 showed a time- and dose-dependent killing of both a clindamycin-resistant and a clindamycin-sensitive P. acnes isolate. Gel shift experiments indicated that, like the parent compound, NAI003 retained the ability to bind to elongation factors Tu (EF-Tus) derived from Escherichia coli, E. faecalis, or P. acnes, albeit with reduced efficiency. In contrast, EF-Tus derived from the NAI003-insensitive Staphylococcus aureus or Streptococcus pyogenes did not bind this compound. These results were confirmed by in vitro studies using a hybrid translation system, which indicated that NAI003 can inhibit most efficiently protein synthesis driven by the P. acnes EF-Tu. P. acnes mutants resistant to NAI003 were isolated by direct plating. With one exception, all analyzed strains carried mutations in the tuf gene, encoding EF-Tu. Because of its selective effect on P. acnes in comparison to resident skin flora, NAI003 represents a promising candidate for the topical treatment of acne, which has already completed a phase 1 clinical study.

    Objective: Typically regarded as an adolescent condition, acne among adult females is also prevalent. Limited data are available on the clinical characteristics and burden of adult female acne. The study objective was to describe clinical characteristics and psychosocial impact of acne in adult women. Design: Cross-sectional, web-based survey. Setting: Data were collected from a diverse sample of United States females. Participants: Women ages 25 to 45 years with facial acne (≥25 visible lesions). Measurements: Outcomes included sociodemographic and clinical characteristics, perceptions, coping behaviors, psychosocial impact of acne (health-related quality of life using acne-specific Quality of Life questionnaire and psychological status using Patient Health Questionnaire), and work/productivity. Results: A total of 208 women completed the survey (mean age 35±6 years), comprising White/Caucasian (51.4%), Black/African American (24.5%), Hispanic/Latino (11.1%), Asian (7.7%), and Other (5.3%). Facial acne presented most prominently on cheeks, chin, and forehead and was characterized by erythema, postinflammatory hyperpigmentation, and scarring. Average age of adult onset was 25±6 years, and one-third (33.7%) were diagnosed with acne as an adult. The majority (80.3%) had 25 to 49 visible facial lesions. Acne was perceived as troublesome and impacted self-confidence. Makeup was frequently used to conceal acne. Facial acne negatively affected health-related quality of life, was associated with mild/moderate symptoms of depression and/or anxiety, and impacted ability to concentrate on work or school. Conclusion: Results highlight the multifaceted impact of acne and provide evidence that adult female acne is under-recognized and burdensome. PMID:24578779

    2011-12-01

    Atrophic facial acne scarring is a widely prevalent condition that can have a negative impact on a patient's quality of life. The appearance of these scars is often worsened by the normal effects of aging. A number of options are available for the treatment of acne scarring, including chemical peeling, dermabrasion, ablative or nonablative laser resurfacing, dermal fillers, and surgical techniques such as subcision or punch excision. Depending on the type and extent of scarring, a multimodal approach is generally necessary to provide satisfactory results. Resurfacing techniques correct surface irregularities, long-lasting dermal fillers address the volume loss resulting from acne, and sub-superficial musculoaponeurotic system (SMAS) face-lift procedures counter the soft tissue laxity and ptosis associated with aging. This article briefly reviews the evolution of individual approaches to treating atrophic acne scarring, followed by case examples illustrating results that can be achieved using a multimodal approach. Representative cases from patients in their 30s, 40s, and 50s are presented. In the author's clinical practice, multimodal approaches incorporating fractionated laser, injectable poly-L: -lactic acid, and sub-SMAS face-lift procedures have achieved optimal aesthetic outcomes, high patient satisfaction, and durability of aesthetic effect over time.

    Acne is a common skin disorder characterized by follicular hyperkeratinization and obstruction of the pilosebaceous follicles, androgen stimulated sebum production, colonization of the follicles by Propionibacterium acne, and inflammation. A large number of epidemiological studies have shown a low incidence of acne in non-Western societies, suggesting that diet might be an important factor in acne pathogenesis, particularly in mediating inflammation, oxidative stress and androgen stimulation in the acne process. Consequently, it has been hypothesized that diet might have a preventive or therapeutic effect in this skin disorder. Since the majority of recent data have not been consistent, the aim of this article is to present current knowledge and scientific assumptions on the relationship between diet and acne.

    Nicotinamide, also known as niacinamide, is the amide form of vitamin B3. It is a precursor of essential coenzymes for numerous reactions in the body including adenosine triphosphate (ATP) production. Nicotinic acid, also known as niacin, is converted into nicotinamide in the body. The use of topical nicotinamide in the treatment of acne vulgaris; melasma; atopic dermatitis; rosacea; and oral nicotinamide in preventing nonmelanoma skin cancer is discussed. The possible side effects and consequences of excessive nicotinamide exposure are reviewed, including suggestions nicotinamide might have a role in the development of diabetes, Parkinson's disease, and liver damage.

    This review highlights clinically important findings about acne treatment identified in nine systematic reviews published or indexed in the period March 2009 to February 2010. A systematic review of dietary influences on acne suggested that a possible role of dietary factors in acne cannot be dismissed, as the studies to date have not been sufficiently large or robust. Another review looked at benzoyl peroxide, which may be enjoying a comeback because of increasing bacterial resistance to antibiotics, and suggested that there was a lack of evidence that stronger preparations were more effective than weaker ones. The same team also carried out a systematic review addressing the question of whether topical retinoids cause an initial worsening of acne. They found no evidence to suggest initial worsening of acne severity, although there was evidence of skin irritation that typically settled by 8-12 weeks. A review of oral isotretinoin and psychiatric side-effects reinforced a possible link between the two, although it pointed out that the better-quality primary studies were still inconclusive. An updated Cochrane Review confirmed the efficacy of combined oral contraceptives (COCs) in reducing acne lesion counts. It also found that the evidence to support COCs containing cyproterone acetate over others was very limited. Another Cochrane Review failed to show any benefit of spironolactone for acne, based on limited studies. Three reviews examined laser and light therapies, and found some evidence of superiority only for blue or blue/red light treatment over placebo light, but a general absence of comparisons against other acne treatments. Photodynamic therapy had consistent benefits over placebo but was associated with significant side-effects and was not shown to be better than topical adapalene. PMID:20738323

    The kidneys are important organs which have many functions in the body, including the production of hormones, absorbtion of minerals and the filtration of blood, producing urine. Their failure can be fatal, therefore, to focus the study of such herbs which may be useful in treating renal disease is the need of hour. In Pakistan, Cucumis melo and Berberis vulgaris has been commonly used for renal problems. In both of these plants were found flavonoids, alkaloids and terpenes, which may stand for their renal protective properties. Their reported vitamin E contents and antioxidant potentials also provide a base for their defensive mechanism, may be due to their free radical scavenging properties. Further, their diuretic and urinary tract anti-ulcer properties also support their traditional use in renal diseases. Their anti-histaminic and anti-cholinergic properties also provide symptomatic treatment by decreasing prostaglandin level and due to antispasmodic properties. Concluding, both of these plants can be used for renal problems, especially Cucumis melo, which have both the nutritive and medicinal properties. Therefore, the renal disease patients are advised to take much of this particular fruit, especially their seeds to make their kidneys healthy. PMID:26647620

    Effects of soaking, cooking and autoclaving on changes in polyphenols, phytohaemagglutinating activity, phytic acid, hydrogen cyanide (HCN), oligosaccharides and in vitro protein digestibility were investigated in seeds of Dolichos lablab var. vulgaris. Both distilled water and NaHCO3 solution soaking and autoclaving significantly reduced the contents of total free phenolics (85-88%) compared to raw seeds. Autoclaving (45 min) reduced the content of tannins by upto 72%. Soaking seemed to have limited effect in eliminating phytohaemagglutinating activity, whereas autoclaving (45 min) seemed to eliminate the haemagglutinating activity completely. The reduction in content of phytic acid was found to be some what greater in distilled water soaking (28%) compared to NaHCO3 solution soaking (22%). Only a limited loss in content of phytic acid was observed under cooking as well as autoclaving. Loss of HCN was greater under autoclaving (87%) compared to the other processes studied. Of the three sugars analysed, soaking reduced the level of verbascose more than that of stachyose and raffinose. Autoclaving reduced the content of oligosaccharides more efficiently (67-86%) than ordinary cooking (53-76%). Autoclaving improved the in vitro protein digestibility (IVPD) significantly (13%). Of all the different water and hydrothermal treatments studied autoclaving seemed to be the most efficient method in improving IVPD and eliminating the antinutrients investigated except phytic acid.

    Propionibacterium acnes is the most abundant bacterium on human skin, particularly in sebaceous areas. P. acnes is suggested to be an opportunistic pathogen involved in the development of diverse medical conditions but is also a proven contaminant of human clinical samples and surgical wounds. Its significance as a pathogen is consequently a matter of debate. In the present study, we investigated the presence of P. acnes DNA in 250 next-generation sequencing data sets generated from 180 samples of 20 different sample types, mostly of cancerous origin. The samples were subjected to either microbial enrichment, involving nuclease treatment to reduce the amount of host nucleic acids, or shotgun sequencing. We detected high proportions of P. acnes DNA in enriched samples, particularly skin tissue-derived and other tissue samples, with the levels being higher in enriched samples than in shotgun-sequenced samples. P. acnes reads were detected in most samples analyzed, though the proportions in most shotgun-sequenced samples were low. Our results show that P. acnes can be detected in practically all sample types when molecular methods, such as next-generation sequencing, are employed. The possibility of contamination from the patient or other sources, including laboratory reagents or environment, should therefore always be considered carefully when P. acnes is detected in clinical samples. We advocate that detection of P. acnes always be accompanied by experiments validating the association between this bacterium and any clinical condition. PMID:26818667

    Propionibacterium acnes subsp. acnes subsp. nov. and Propionibacterium acnes subsp. elongatum subsp. nov. are described. These emanate from the three known phylotypes of P. acnes, designated types I, II and III. Electron microscopy confirmed the filamentous cell shape of type III, showing a striking difference from types I/II, which were short rods. Biochemical tests indicated that, in types I/II, either the pyruvate, l-pyrrolidonyl arylamidase or d-ribose 2 test was positive, whereas all of these were negative among type III strains. Matrix-assisted laser-desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) spectra, which profile mainly their ribosomal proteins, were different between these two groups. Surface-enhanced laser-desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS) spectra of all phylotypes revealed a specific protein biomarker that was overexpressed in type III strains compared with types I/II only when grown aerobically. Reference strains had high whole-genome similarity between types I (>91 %) and II (>75 %), but a considerably lower level of 72 % similarity with type III. recA and gyrB sequence dendrograms confirmed the distant relatedness of type III, indicating the presence of two distinct centres of variation within the species P. acnes. On the other hand, cellular fatty acid profiles and 16S rRNA gene sequence relatedness (>99.3 %) circumscribed the species. Thus, we propose two subspecies, Propionibacterium acnes subsp. acnes subsp. nov. for types I/II and Propionibacterium acnes subsp. elongatum subsp. nov. for type III. The type strain of Propionibacterium acnes subsp. acnes is NCTC 737T ( = ATCC 6919T = JCM 6425T = DSM 1897T = CCUG 1794T), while the type strain of Propionibacterium acnes subsp. elongatum is K124T ( = NCTC 13655T = JCM 18919T).

    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

    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.

    Physical-mechanical exfoliation with the nonwoven polyester fiber web sponge is an effective adjunct to the treatment of comedonal and pustular acne. Precisely controlled epidermabrasion is achieved by varying pressure, velocity, duration and frequency of use. Side effects are negligible and patient acceptance is high. Effectiveness is not dependent upon erythema and scaling since the web sponge mechanically removes keratin excrescences and trapped hairs in pilosebaceous ducts. PMID:138554

    New compounds are needed to treat acne and superficial infections caused by Propionibacterium acnes and Staphylococcus aureus due to the reduced effectiveness of agents used at present. Long-chain polyunsaturated fatty acids (LC-PUFAs) are attracting attention as potential new topical treatments for Gram-positive infections due to their antimicrobial potency and anti-inflammatory properties. This present study aimed to investigate the antimicrobial effects of six LC-PUFAs against P. acnes and S. aureus to evaluate their potential to treat infections caused by these pathogens. Minimum inhibitory concentrations were determined against P. acnes and S. aureus, and the LC-PUFAs were found to inhibit bacterial growth at 32-1024 mg/L. Generally, P. acnes was more susceptible to the growth inhibitory actions of LC-PUFAs, but these compounds were bactericidal only for S. aureus. This is the first report of antibacterial activity attributed to 15-hydroxyeicosapentaenoic acid (15-OHEPA) and 15-hydroxyeicosatrienoic acid (HETrE), while the anti-P. acnes effects of the six LC-PUFAs used herein are novel observations. During exposure to the LC-PUFAs, S. aureus cells were killed within 15-30 min. Checkerboard assays demonstrated that the LC-PUFAs did not antagonise the antimicrobial potency of clinical agents used presently against P. acnes and S. aureus. However, importantly, synergistic interactions against S. aureus were detected for combinations of benzoyl peroxide with 15-OHEPA, dihomo-γ-linolenic acid (DGLA) and HETrE; and neomycin with 15-OHEPA, DGLA, eicosapentaenoic acid, γ-linolenic acid and HETrE. In conclusion, LC-PUFAs warrant further evaluation as possible new agents to treat skin infections caused by P. acnes and S. aureus, especially in synergistic combinations with antimicrobial agents already used clinically.

    Background: Acne is the most common disorder treated by dermatologists. As many as 80-90% of all adolescents have some type of acne and 30% of them require medical treatment. It is an inflammatory disease of the pilosebaceous unit characterized by the formation of open and closed comedones, papules, pustules, nodules, and cysts. Aims: The present study was conducted to investigate the in vitro anti-acne activity of two Unani single drugs Darchini (Cinnamomum zeylanicum Bl.) and Tukhm Khashkhash (Papaver somniferum L. seeds). Materials and Methods: The antibacterial activity of aqueous, ethanolic and hydroalcoholic extracts of both drugs were investigated against two acne causing bacteria, i.e., Propionibacterium acne and Staphylococcus epidermidis using well diffusion method. Results: The result showed that both drugs were active against the two bacteria. Against P. acne aqueous and ethanolic extract of Darchini and Tukhm Khashkhash showed the zone of inhibition of 18 ± 1.02 mm and 18 ± 1.6 mm and 13 ± 1.04 mm and 14 ± 1.8 mm, respectively. Against S. epidermidis aqueous, hydroalcoholic and ethanolic extracts of Darchini showed 22 ± 1.7 mm, 22 ± 1.2 mm and 15 ± 1.8 mm zone of inhibition respectively. Hydroalcoholic and ethanolic extracts of Tukhm Khashkhash showed 15 ± 1.09 mm and 13 ± 1.6 mm zone of inhibition respectively. Conclusion: This suggests that C. zeylanicum and P. somniferum have potential against acne causing bacteria and hence they can be used in topical anti-acne preparations and may address the antibiotic resistance of the bacteria.

    2014-01-01

    SUMMARY Propionibacterium acnes is known primarily as a skin commensal. However, it can present as an opportunistic pathogen via bacterial seeding to cause invasive infections such as implant-associated infections. These infections have gained more attention due to improved diagnostic procedures, such as sonication of explanted foreign materials and prolonged cultivation time of up to 14 days for periprosthetic biopsy specimens, and improved molecular methods, such as broad-range 16S rRNA gene PCR. Implantassociated infections caused by P. acnes are most often described for shoulder prosthetic joint infections as well as cerebrovascular shunt infections, fibrosis of breast implants, and infections of cardiovascular devices. P. acnes causes disease through a number of virulence factors, such as biofilm formation. P. acnes is highly susceptible to a wide range of antibiotics, including beta-lactams, quinolones, clindamycin, and rifampin, although resistance to clindamycin is increasing. Treatment requires a combination of surgery and a prolonged antibiotic treatment regimen to successfully eliminate the remaining bacteria. Most authors suggest a course of 3 to 6 months of antibiotic treatment, including 2 to 6 weeks of intravenous treatment with a beta-lactam. While recently reported data showed a good efficacy of rifampin against P. acnes biofilms, prospective, randomized, controlled studies are needed to confirm evidence for combination treatment with rifampin, as has been performed for staphylococcal implant-associated infections.

    Red kidney beans were subjected to high hydrostatic pressure (HHP) treatment (50, 150, 250, 350, 450 MPa) and phytohaemagglutinin (PHA) was then extracted by affinity chromatography. It appeared that HHP treatment could increase crude extract yield and decrease its haemagglutination activity. For purified samples, PHA yield was not affected at pressures <450 MPa while the haemagglutination activity was noticeably reduced at 450 MPa. The structural changes were investigated using electrophoresis, size exclusion chromatography (SEC), Fourier transform infrared (FTIR) and differencial scanning calorimetry (DSC). Electrophoresis and SEC profiles revealed a new high molecular weight polymer after 450 MPa treatment. At pressures <450 MPa, FTIR showed an increase in β-sheet structure and a decrease in α-helix. At 450 MPa, the bands at 1688 cm(-1), representing aggregate strands and random coils, increased. The conclusions are that pressures <450 MPa can cause PHA unfolding and induce PHA aggregation at 450 MPa. PMID:23194535

    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

    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
