A small cadre of antimicrobials are commonly used and regarded as effective and safe, as systemic and topical treatments of acne vulgaris. These include oral tetracycline, doxycycline, minocycline and topical clindamycin and erythromycin. Topical antimicrobials work via both antimicrobial and non-antimicrobial mechanisms: the former due to suppression of the growth of propionibacterial species (especially Propionibacterium acnes and P. granulosum). Clindamycin appears to be superior in efficacy compared with erythromycin and tetracycline. However, the emergence and spread of resistance among propionibacteria to both erythromycin and clindamycin calls into question their long-term viability as topical anti-acne therapies. Only through judicious use of combination topical therapies (e.g., topical retinoid, benzoyl peroxide or azelaic acid plus clindamycin or erythromycin) and the practice of effective infection control (i.e., handwashing between seeing patients in the clinic) can both clindamycin's and erythromycin's widespread utility be preserved in this disorder. 相似文献

Topical acne therapies are widely used for the treatment of mild to moderately severe acne vulgaris. However, many available treatments have limitations associated with their use, including lengthy time to response, cosmetic acceptability, and photosensitivity. Combinations of topical antibiotics and comedolytics are especially useful, but some formulations have stability challenges. A new combination formulation that contains 1% clindamycin and 5% benzoyl peroxide (BenzaClin Topical Gel) is currently available. In clinical trials, clinical improvement occurred at the first two follow-up visits and continued throughout treatment. In addition, combination therapy with clindamycin/benzoyl peroxide gel rapidly reduces Propionibacteria acnes counts and suppresses the emergence of clindamycin-resistant P. acnes. This formulation is stable at room temperature for up to 2 months after compounding. The aqueous gel vehicle is less drying, and there is no photosensitivity associated with its use. This study compares the combination treatment of 1% clindamycin and 5% benzoyl peroxide topical gel with other therapeutic options for mild to moderately severe acne vulgaris. 相似文献

Context and objective: Acne vulgaris, an inflammatory skin disease with different clinical appearances, is a common problem in most adolescents. It seems that using combinations of topical agents can decrease resistance to the treatment and improve the efficacy. Therefore, we evaluated the effects of azelaic acid (AA) 5% and clindamycin (Clin) 2% combination (AA-Clin) on mild-to-moderate acne vulgaris. Materials and methods: The efficacy and safety of 12-week treatment with AA-Clin in patients with mild-to-moderate facial acne vulgaris were evaluated by a multicenter, randomized, and double-blind study. A total of 88 male and 62 female patients were randomly assigned to one of these treatments: AA 5%, Clin 2%, and combination of them. Every 4 weeks, total inflammatory and noninflammatory lesions were counted, acne severity index (ASI) was calculated, and patient satisfaction was recorded. Results: Treatment for 12 weeks with combination gel significantly reduced the total lesion number compared with baseline ( p?<?0.01), as well as Clin 2% or AA 5% treatment groups ( p?<?0.05 or p?<?0.01). The percentage of reduction in ASI in combination treated group (64.16?±?6.01) was significantly more than those in the Clin 2% (47.73?±?6.62, p?<?0.05) and 5% AA (32.46?±?5.27, p?<?0.01) groups after 12 weeks. Among the patients in the AA-Clin group, 75.86% of males were satisfied or very satisfied and 85.71% of females were satisfied or very satisfied. This trend was significant in comparison to the number of patients who were satisfied with AA 5% or Clin 2% treatment ( p?<?0.01). Seven patients in AA-Clin group (incidence?=?22%) showed adverse effects that were not statistically significant compared to treatment with individual active ingredients. Discussion and conclusion: The profound reduction in lesion count and ASI by combination therapy with AA-Clin gel in comparison to individual treatment with 5% AA or Clin 2% suggested the combination formula as an effective alternative in treatment of acne vulgaris. 相似文献

Clindamycin phosphate is the most widely used topical antibacterial agent for acne treatment. Treatment of patients with mild to moderate acne vulgaris with a new foam formulation (clindamycin foam, CF) for 12 weeks was at least as effective as clindamycin gel (CG) based on the Investigator's Static Global Assessment (ISGA) score. CF was superior to CG based on the reduction from baseline in total (P = .0014), inflammatory (P = .0478), and noninflammatory (P = .0037) acne lesion counts. Additionally, CF achieved efficacy that was superior to that of vehicle foam based on ISGA score (P = .0025) and all 3 lesion counts (all P < .05). Adverse experiences in the active treatment groups were mild or moderate and transient in nature. Thus the foam formulation of clindamycin is a safe and effective acne treatment; the unique foam delivery vehicle may offer cosmetic benefits to the patient and thus increase compliance. 相似文献

BACKGROUND: Achieving an effective management of acne vulgaris with minimal complications remains a difficult challenge for physicians. Moreover, the rise in antibiotic-resistant strains reduce the future usefulness of current mainstay therapies, and accordingly, the need for alternative therapies is mandatory. Phototherapy has been shown to be an effective treatment for acne, and there has been a renewed interest in photodynamic therapy as a treatment modality for this condition. OBJECTIVES: To evaluate the effectiveness of pulsed dye laser (PDL), intense pulsed light (IPL) and light-emitting diode (LED) phototherapy for the treatment of moderate to severe acne vulgaris. METHODS: Forty-five patients with moderate to severe acne were randomly divided into 3 equal groups. Group 1 was treated with a PDL, group 2 was treated with IPL, and group 3 was treated with a blue-red combination LED. Treatment was continued until a > or = 90% clearance of patient lesions was achieved. Clinical assessments were conducted before starting treatment, at 1 month as a midpoint evaluation, and after the final treatment session. RESULTS: Patients treated with the PDL reached a > or = 90% clearance of their inflammatory lesions after a mean of 4.1 +/- 1.39 sessions, while patients treated with IPL required a mean of 6 +/- 2.05 sessions. Patients treated with the LED required a mean of 10 +/- 3.34 sessions. At the mid-point evaluation, the percent reduction in acne lesions treated with the PDL was 90% or more, in cases of IPL and the LED, the percent reductions were 41.7% and 35.3%, respectively. Laser and light phototherapy sessions were well tolerated with minimal adverse events experienced as being mild and usually self-limiting. CONCLUSIONS: The encouraging results of the present study contributes evidence of phototherapy as useful therapeutic option for treatment of moderate to severe acne, and validates further studies to evaluate treatments with a larger number of patients and for a longer period of follow-up. 相似文献

In the treatment of mild to moderate acne vulgaris, the combination of an antibiotic and benzoyl peroxide provides enhanced efficacy over the individual agents, with the potential to decrease the emergence of resistant strains of P. acnes. To evaluate treatment regimens combining the daily use of a clindamycin/benzoyl peroxide gel, a tretinoin gel, and a clindamycin gel, the current randomized, evaluator-blind study was conducted. Results demonstrate that once-daily administration of clindamycin/benzoyl peroxide gel (combination formulation) was as effective as clindamycin/benzoyl peroxide gel + tretinoin gel + clindamycin gel. Both of these regimens provided greater efficacy than tretinoin + clindamycin. Treatment with clindamycin/benzoyl peroxide demonstrated a significant benefit over other treatments at Week 2, highlighting its rapid onset of action. All regimens were safe and generally well tolerated, with less severe peeling seen in patients who received clindamycin/benzoyl peroxide. In conclusion, the regimens that included clindamycin/benzoyl peroxide were more effective than tretinoin + clindamycin in the treatment of acne vulgaris, with no clinical advantage of adding tretinoin + clindamycin to once-daily clindamycin/benzoyl peroxide treatment. 相似文献

Healthy skin protects us against a multitude of insults, but injured or maladapted skin can lead to infection, inflammation, or worse. Fortunately, naturally occurring bioactive products, many commonly found in olive oil and other plant and vegetable extracts, have shown utility in treating skin and related diseases as well as conditioning the skin to maintain its healthy function. Powerful agents targeting nuclear regulatory pathways continue to hold promise as new or repurposed therapies for a wide variety of ills and skin conditions. Epigenetic approaches that activate Nrf2 to effect detoxification, redox balance, DNA repair, and mitochondrial function are noteworthy. Some of the disease applications being actively investigated range from eczema and psoriasis to skin cancer and diabetes-related wound healing to name just a few. 相似文献

OBJECTIVE: Treatment of acne vulgaris with light sources necessitates multiple targets including Propionibacterium acnes and sebaceous glands. Traditional light sources such as blue light capitalize on P acnes bacteria as targets while infrared lasers and radiofrequency devices target the sebaceous gland. A novel device combining vacuum and a unique broadband light source was designed to combine multiple targets for the effective treatment of acne. The objective of this study was to demonstrate the safety and efficacy of a novel device that uses a combination of broadband light and pneumatic energy for the treatment of acne vulgaris. METHODS: In a retrospective multicenter study, clinical data were collected from 56 patients with mild to severe acne. Patients had been treated 2 to 4 times with a portable photopneumatic device (Aesthera PPx, Aesthera Corporation, Pleasanton, CA) that delivers broadband light (400 to 1200 nm) to the treatment site via a hand piece. For 11 of the 56 patients, 3 independent physicians blinded to the study treatment or duration evaluated PPx efficacy by comparing photographs taken before and after PPx treatment. RESULTS: For the 56 patients, the median physician-rated clearance increased from 50% after a single treatment to 90% after the fourth treatment, whereas the median patient-rated clearance improved from 50% after a single treatment to 78% after the fourth treatment. On a 4-point scale, both physician-rated and patient-rated median overall satisfaction levels increased from a 3 after a single treatment, to 4 after the second, third, and fourth treatments. Clinically significant adverse events were not observed. For the 11 patients evaluated by photography, the median papule and pustule lesion counts decreased from 8 to 3 and from 2 to 0, respectively. Median acne severity (Burton scale) decreased from 4 before treatment to 2 after the final treatment, and the median improvement was 4.5 (scale 1-5). The median erythema rating decreased from 2 before treatment to 1 after the final treatment (scale 1-4). Adverse events were limited to mild erythema. The median acne clearance was 3 (scale 1-4). CONCLUSION: Photopneumatic technology provides a safe and effective treatment of mild to severe acne vulgaris. 相似文献

The successful treatment of acne still remains problematic. Conventional therapies often prove inconsistent with unacceptable side effects and recurrence rates, leading to patient noncompliance. A thermal phototherapy treatment using a combination of blue light and red light has recently attracted much attention and seems to offer an effective alternative. The objective of this study was to evaluate the efficacy of blue light (415 nm) in combination with red light (633 nm) in the reduction of inflammatory lesions on the face of subjects (n=21) with mild to moderate acne vulgaris after a course of 8 20-minute (blue) or 30-minute (red) alternated light treatments, self-administered by a handheld unit over a period of 4 weeks. Lesion counts progressively reduced throughout the 4-week light therapy period and continued to reduce up to 8 weeks posttherapy, with a final average reduction of 69% seen 8 weeks after the treatment course (P>.001). This pattern is similar to previously reported studies. 相似文献

Topical retinoids offer highly effective treatment for both inflammatory and non-inflammatory acne, with tazarotene demonstrating greater efficacy than other topical retinoids. A multicenter, double-blind, randomized, parallel-group trial has been performed to evaluate whether the adjunctive use of clindamycin/benzoyl peroxide could enhance the efficacy of tazarotene still further. Patients with moderate to severe inflammatory acne applied tazarotene 0.1% cream each evening and were randomly assigned to morning applications of vehicle gel or a ready-to-dispense formulation of clindamycin 1%/benzoyl peroxide 5 % gel containing 2 emollients. Tazarotene/clindamycin/benzoyl peroxide achieved a significantly greater reduction in comedo count than tazarotene monotherapy and, among patients with a baseline papule plus pustule count of > or =25 (the median value), a significantly greater reduction in inflammatory lesion count. The combination therapy was also at least as well-tolerated as tazarotene monotherapy. The adjunctive use of clindamycin/benzoyl peroxide gel with tazarotene cream promotes greater efficacy and may also enhance tolerability. Any improvements in tolerability could be due to the emollients in the clindamycin/benzoyl peroxide gel formulation. 相似文献

Clindamycin phosphate 1.2% and tretinoin 0.025% gel (CLIN/RA gel [ZIANA Gel]) is a novel topical combination agent approved by the FDA for the treatment of acne vulgaris in patients 12 years of age or older. A solution of clindamycin phosphate 1.2% combined with partially solubilized and crystalline tretinoin 0.025% suspended in an aqueous-based, alcohol-free gel formulation, CLIN/RA gel was studied in 2 randomized, vehicle-controlled trials involving more than 4,500 patients. Efficacy results from these studies showed that treatment with the combination significantly reduced lesion counts and improved patients' overall appearance to a greater extent than the individual components. Individual ingredients and the combination were well-tolerated. Among those treated with the combination formulation, discontinuation rates due to adverse events were 1% or less. 相似文献

Introduction: Acne vulgaris is the most common skin disease worldwide, yet current treatment options, although effective, are associated with unwanted side effects, chronicity, relapses and recurrences. The adequate control of the four pathogenic mechanisms involved in the appearance of acne lesions is key to treatment success. This paper aims to discuss the novel treatment modalities that have surfaced in consequence of new knowledge obtained in acne pathogenesis. Areas covered: Pathogenic pathways are evaluated and discussed throughout the paper in relation to the mechanisms of action of novel molecules being investigated for the treatment of acne vulgaris. A comprehensive search was made in PubMed and Clinicaltrial.gov using a different combination of keywords, which included acne vulgaris, treatment, therapy, and therapeutic. Expert opinion: In the near future, more effective treatments with less side effects are expected. The use of topical anti-androgens, coenzyme-A carboxylase inhibitors, and insulin growth factor-1inhibitors to control sebum production seem promising. Selective RAR-agonists have the potential of becoming an alternative to the currently available retinoid therapy in the management of infundibular dyskeratosis with a better safety profile. Antibiotic use will probably decline as more effective options for controlling Cutinebacterium acnes colonization and the inflammation cascade emerge. 相似文献
